Methodological quality (risk of bias) assessment tools for primary and secondary medical studies: what are they and which is better?

Ultrasound screening of paediatric non-alcoholic fatty liver disease (NAFLD): A critical literature review

INTRODUCTION

Paediatric NAFLD is an increasing global health concern, which can be effectively managed with early detection. Screening, using accurate, affordable, and accessible tests is recommended, however, there is currently no consensus on the most appropriate tests. Although ultrasound techniques are widely used, their performance against reference tests have not been fully assessed.

METHODS

A literature search of related databases for peer-reviewed original articles published from January 2010-March 2024 was conducted. Appropriate tools were used to systematise and document the search results and selected studies were quality assessed and critically appraised. Extracted data was subjected to thematic analysis and narrative synthesis.

RESULTS

Eighteen articles met the inclusion criteria. B-mode and Quantitative ultrasound techniques were compared against MR spectroscopy, MRI-PDFF and Liver biopsy.

CONCLUSION

Liver echogenicity and Steato-scores were the B-mode methods used. The former was less effective, with a maximum reported sensitivity of 70%. The latter reached up to 100% sensitivity, and >80% specificity. Ultrasound performed better with moderate-severe steatosis. There was not enough evidence to support steatosis grading, possibly due to small sample sizes and lack of established cut-off values. QUS (Quantitative Ultrasound)) methods including Continuous Attenuation Parameter (CAP), Attenuation Coefficient (AC), Ultrasound derived fat fraction (UDFF), Tissue Scatter Imaging (TSI) Hepato-Renal Index (HRI), Heterogeneity Index (HIA), Computer Assisted Ultrasound (CAUS) and Picture Archiving and Communication System (PACS-based Image analysis performed better than B-mode methods. Although QUS demonstrated excellent performance, with sensitivity and specificity of up to 100%, this will require further verification before implementation in practice.

PRACTICE IMPLICATIONS

Ultrasound techniques can effectively be used for paediatric NAFLD screening, especially in higher-risk subjects. The steato-scores method is currently recommendable for this, with excellent potential for the use of QUS, after cut-off values and validation requirements have been addressed.

Growth monitoring and promotion service utilization and its associated factors among mothers of children under two years in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Growth monitoring and promotion (GMP) is a nutritional intervention designed to identify and address growth faltering before a child's nutritional status deteriorates into severe malnutrition. Despite GMP being recognized as a priority in Ethiopia's national nutrition program, there is no national aggregated figure to show the extent of GMP service utilization. Therefore, this systematic review and meta-analysis aimed to assess GMP service utilization and associated factors in Ethiopia.

METHODS

A systematic literature search was conducted using PubMed/MEDLINE, CINAHL, Hinari, EMBASE, Scopus, and grey literature sources like Google Scholar, WorldCat, and Institutional repository. The Joanna Briggs Institution (JBI) quality assessment tool was used to appraise the quality of the articles, and articles scoring > 50% were included in the analysis. The pooled prevalence and odds ratio of associated factors with 95%CI was computed using STATA version 16. A random-effect model was employed to estimate the effect size, and I-squared statistics and Egger's test were used to assess heterogeneity and identify potential publication bias, respectively. Subgroup analysis was conducted with publication year, sample size, and region to identify the source of heterogeneity.

RESULTS

Nine studies with 4,768 study participants were included in this meta-analysis. The overall pooled utilization of GMP service among children under two years of age in Ethiopia was 23.21% (95% CI: 16.02, 30.41, I2 = 97.27% & P = 0.0001). Mothers who received counselling on GMP service (OR = 3.16 (95%CI: 2.49-4.00), parents who use family health card (FHC) (OR = 3.29 (95%CI: 1.49-7.28), and mother who use postnatal care (OR = 3.93 (95%CI: 2.40-6.42), and Anti natal care (OR = 3.15 (95%CI: 1.29-7.69) were the factors associated with GMP service utilization among children under two years of age.

CONCLUSIONS

The utilization of GMP services among children under the age of two in Ethiopia remains inadequate. Therefore, it is crucial to provide health education and counselling focusing on GMP to the mothers/caregivers of the child and encourage utilization of FHC. In addition, integrating GMP with other maternal health services should be promoted.

Prophylactic pancreatic duct stenting to reduce the risk of post-ampullectomy pancreatitis: a comprehensive review and meta-analysis of 1858 patients

BACKGROUND

The effectiveness of prophylactic pancreatic duct stenting (PPDS) in preventing post-ampullectomy pancreatitis (PAP) at the time of endoscopic ampullectomy (EA) has been reported, however, results are conflicting. We conducted a systematic review and meta-analysis looking at the use of PPDS in reducing PAP as well as overall post-ampullectomy complications.

METHODS

Multiple databases were searched through May 2023 for studies reporting on EA. Meta-analysis was performed to determine pooled proportions and relative risk (RR) with 95% confidence intervals (CI) of PAP, with and without PPDS. Pooled rates of adverse events including perforation, delayed bleeding, cholangitis, and procedure related mortality were assessed. Random effects model was used for our meta-analysis and heterogeneity was assessed using the I2 statistics.

RESULTS

Thirty-four studies (14 case series, 18 cohort studies and 2 randomized controlled trials) with 1868 patients were included. The overall pooled rate of PAP was 12.3% (CI 10.3-14.5). We found no statistically significant difference in rates of PAP among patients with PPDS, 11.9% (CI 8.9-15.7) and without PPDS, 16.6% (CI 13.4-20.4), RR 0.8 (CI 0.51-1.28), p = 0.4. In terms of severe PAP, we found no difference between the two groups. The overall pooled rates of successful en-bloc and piecemeal resection were 74.8% (CI 67.3-81.1) and 25.1% (CI 19-32.4). Additionally, pooled rates of ampullary stenosis, post procedural bleeding, perforation, cholangitis, and procedure related mortality were 3.6%, 11.1%, 4.2%, 3.5%, and 1.3%, respectively.

CONCLUSIONS

Our analysis shows that PPDS at the time of EA does not offer a significant protective effect against PAP. While the incidence of PAP was higher among the no PPDS group, it is plausible that this is more likely due to variation among studies in terms of lesion size, length/size of pancreatic stent used and etiology of ampullary lesions. Future well-designed randomized controlled trials are needed to validate our findings.

Mortality rate and predictors of colorectal cancer patients in Ethiopia: a systematic review and meta-analysis

INTRODUCTION

The incidence of colorectal cancer (CRC) has been increasing in Sub-Saharan countries, including Ethiopia. However, the real mortality rate for CRC patients in Ethiopia has not been established. Therefore, this systematic review and meta-analysis aimed to determine the overall mortality rate and identify predictors among CRC patients in Ethiopia.

METHODS

PubMed, EMBASE, Web of Science, Scopus, Science Direct, and Google Scholar were searched to identify relevant articles. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) were followed. The quality of the included studies was assessed using the Newcastle-Ottawa Scale Critical Appraisal checklist. A random effect model was used to estimate the pooled mortality rate and adjusted hazard ratio (AHR). Publication bias was assessed using funnel plots and Egger's regression test, while heterogeneity was evaluated through the Cochran Q test and I2 statistics.

RESULTS

After reviewing 74 articles, only 7 studies met the criteria and were included in the analysis. The analysis revealed that the overall mortality rate among CRC patients in Ethiopia was 40.5% (95% confidence interval [CI]: 32.05, 48.87) while the survival rates at 1 year, 3 years, and 5 years were 82.3% (95% CI: 73.33, 91.31), 48.8% (95% CI: 43.35, 54.32), and 26.6% (95% CI: 21.26, 31.91) respectively. Subgroup analysis indicated that studies conducted after 2017 had higher mortality rates compared to those studied earlier (43.0% vs. 38.2%). Older age (AHR: 1.89, 95% CI: 1.27, 2.82); being married (AHR: 2.53, 95% CI: 1.79, 3.57); having comorbidities (AHR: 1.84, 95% CI: 1.45, 2.35); having high CEA levels (AHR: 2.06, CI: 1.35, 3.13); being in stage II (AHR: 4.13, 95% CI: 1.85, 9.22), III (AHR: 8.62, 95% CI: 3.88, 19.15), and IV (AHR: 8.06, CI: 2.89, 22.49) were the most important predictors.

CONCLUSION

In Ethiopia, the mortality rate among individuals diagnosed with CRC is high, with two out of five patients dying from this disease. Age, marital status, CEA level, comorbidities, and cancer stage were identified as predictors of mortality in CRC patients. Therefore, early detection and screening should be prioritized, particularly for older patients, those who are married, have comorbidities, elevated CEA levels, and advanced cancer stages.

Echocardiographic assessment of left ventricular mechanics in individuals with mitral valve prolapse: a systematic review and meta-analysis

PURPOSE

During the last decade, a number of echocardiographic studies have employed speckle tracking echocardiography (STE) for assessing myocardial deformation properties in individuals with mitral valve prolapse (MVP), reporting not univocal results. Accordingly, we performed a systematic review and meta-analysis to summarize the main findings of these studies and to examine the overall influence of MVP on left ventricular (LV) global longitudinal strain (GLS).

METHODS

All echocardiographic studies assessing conventional echoDoppler parameters and myocardial strain indices in MVP individuals vs. controls without MVP, selected from PubMed and EMBASE databases, were included. The risk of bias was assessed by using the National Institutes of Health (NIH) Quality Assessment of Case-Control Studies. Continuous data (LV-GLS) were pooled as a standardized mean difference (SMD) comparing MVP group with healthy controls. The overall SMD of LV-GLS was calculated using the random-effect model.

RESULTS

The full-texts of 15 studies with 1088 individuals with MVP and 591 healthy controls were analyzed. Average LV-GLS magnitude was significantly, even though modestly, reduced in MVP individuals in comparison to controls (19.4 ± 3.4% vs. 21.1 ± 2.8%, P < 0.001). The overall effect of MVP on LV-GLS was small-to-medium (SMD - 0.54, 95%CI -0.76,-0.32, P < 0.001). Substantial heterogeneity was detected for the included studies, with an overall I2 statistic value of 75.9% (P < 0.001). Egger's test for a regression intercept gave a P-value of 0.58, indicating no publication bias. On meta-regression analysis, none of the moderators (the age, the percentage of females among MVP individuals, body mass index, heart rate and systolic blood pressure of MVP individuals, the degree of mitral regurgitation, the type of ultrasound machine employed for strain echocardiographic imaging and finally the beta blocker treatment) was significantly associated with effect modification (all P < 0.05). Regional strain analysis, performed by two-third of the studies, highlighted a more enhanced reduction in myocardial strain parameters at level of the LV basal infero-lateral segments in all directions (longitudinal, circumferential and radial), with apical sparing.

CONCLUSIONS

The longitudinal strain impairment detected in MVP individuals is more regional than global, with peculiar involvement of the LV basal infero-lateral segments and relative apical sparing pattern.

A comprehensive picture of using standardized nursing languages in long-term care systems: An integrative review

PURPOSE

This integrative review was conducted to provide a comprehensive picture of the use of standardized nursing languages (SNLs) in long-term care (LTC) systems.

METHODS

A comprehensive search was performed with terminological variants of "standardized terminology" and "long-term care" in eight electronic databases up to December 2021. Eligible studies were further identified by screening the reference lists of publications that met the inclusion criteria. The quality of the included studies was appraised using the Joanna Briggs Institute checklists. The study findings were organized into themes, which represent the focus of the study.

FINDINGS

Eighty-one publications that studied 12 SNLs in 17 countries are presented in this review. The Omaha System, NANDA-I, NIC, and NOC were the most common SNLs. Study foci were classified into five themes: evaluating the applicability of 10 SNLs (n = 22), characterizing nursing care using six SNLs (n = 16), developing core sets and tools based on seven SNLs (n = 15), documenting nursing care by using four SNLs (n = 14), and implementing intervention programs based on six SNLs (n = 14).

CONCLUSIONS AND IMPLICATIONS FOR NURSING

SNLs can be used for various purposes, and the available evidence supports the expansion of their utilization. Further studies should continue to identify gaps in the existing versions of SNLs to reflect the LTC nursing process in multiple societies. Additionally, the successful use of SNLs requires background knowledge of nursing informatics; therefore, preparation should be started in the nursing curriculum and continued in healthcare facilities, including LTC settings. These research findings will assist healthcare managers, researchers, and policymakers in the LTC field in effectively utilizing SNLs.

A Systematic Review of the Quality of Perpetrator Programs' Outcome Studies: Toward A New Model of Outcome Measurement

This systematic review assessed whether studies on the outcomes of perpetrator programs comply with the model recommendations for outcome evaluation. Three databases (PsycINFO, Medline, and Scopus) were used to identify perpetrator program outcome studies from 1988 to 2021. The inclusion criteria were as follows: empirical studies with no time restriction; published in English or Spanish; evaluated interventions aimed at male perpetrators of any type of abuse toward women; evaluated the effectiveness of the intervention in a follow-up post-intervention; and provided an indicator of recidivism. The search and selection process resulted in 46 original studies. The results showed that studies did not include a thorough description of the study sample. Many approaches to psychological intervention are used, with cognitive behavioral therapy being the most widely used. Most studies did not describe the program content. Dropout rates varied greatly from one study to another (from 0% to 64%) and only eight studies provided dropout rates specified by each type of perpetrator. The follow-up period ranged from 3 months to 9 years. The recidivism rates (ranging from 5% to 72.5%), and their assessments were also very different. Only 12 of the 46 studies (26.1%) used more than one source to obtain recidivism rates. In terms of outcomes, few studies considered (ex-) partner accounts. Some studies had other measures of outcome, whereas a few included a pretest-posttest. In summary, these studies do not follow the recommendations of the model.

Antibiotic Prophylaxis and Infective Endocarditis Incidence Following Invasive Dental Procedures: A Systematic Review and Meta-Analysis

Importance

The association between antibiotic prophylaxis and infective endocarditis after invasive dental procedures is still unclear. Indications for antibiotic prophylaxis were restricted by guidelines beginning in 2007.

Objective

To systematically review and analyze existing evidence on the association between antibiotic prophylaxis and infective endocarditis following invasive dental procedures.

Data Sources

PubMed, Cochrane-CENTRAL, Scopus, Web of Science, Proquest, Embase, Dentistry and Oral Sciences Source, and ClinicalTrials.gov were systematically searched from inception to May 2023.

Study Selection

Studies on the association between antibiotic prophylaxis and infective endocarditis following invasive dental procedures or time-trend analyses of infective endocarditis incidence before and after current antibiotic prophylaxis guidelines were included.

Data Extraction and Synthesis

Study quality was evaluated using structured tools. Data were extracted by independent observers. A pooled relative risk (RR) of developing infective endocarditis following invasive dental procedures in individuals who were receiving antibiotic prophylaxis vs those who were not was computed by random-effects meta-analysis.

Main Outcomes and Measures

The outcome of interest was the incidence of infective endocarditis following invasive dental procedures in relation to antibiotic prophylaxis.

Results

Of 11 217 records identified, 30 were included (1 152 345 infective endocarditis cases). Of them, 8 (including 12 substudies) were either case-control/crossover or cohort studies or self-controlled case series, while 22 were time-trend studies; all were of good quality. Eight of the 12 substudies with case-control/crossover, cohort, or self-controlled case series designs performed a formal statistical analysis; 5 supported a protective role of antibiotic prophylaxis, especially among individuals at high risk, while 3 did not. By meta-analysis, antibiotic prophylaxis was associated with a significantly lower risk of infective endocarditis after invasive dental procedures in individuals at high risk (pooled RR, 0.41; 95% CI, 0.29-0.57; P for heterogeneity = .51; I2, 0%). Nineteen of the 22 time-trend studies performed a formal pre-post statistical analysis; 9 found no significant changes in infective endocarditis incidence, 7 demonstrated a significant increase for the overall population or subpopulations (individuals at high and moderate risk, streptococcus-infective endocarditis, and viridans group streptococci-infective endocarditis), whereas 3 found a significant decrease for the overall population and among oral streptococcus-infective endocarditis.

Conclusions and Relevance

While results from time-trend studies were inconsistent, data from case-control/crossover, cohort, and self-controlled case series studies showed that use of antibiotic prophylaxis is associated with reduced risk of infective endocarditis following invasive dental procedures in individuals at high risk, while no association was proven for those at low/unknown risk, thereby supporting current American Heart Association and European Society of Cardiology recommendations. Currently, there is insufficient data to support any benefit of antibiotic prophylaxis in individuals at moderate risk.

Measuring and increasing rates of self-isolation in the context of COVID-19: a systematic review with narrative synthesis

OBJECTIVES

This study aimed to investigate (1) definitions of self-isolation used during the COVID-19 pandemic; (2) measures used to quantify adherence and their reliability, validity, and acceptability; (3) rates of self-isolation adherence; and (4) factors associated with adherence.

STUDY DESIGN

This was a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Synthesis Without Meta-analysis (PRISMA) guidelines (PROSPERO record CRD42022377820).

METHODS

MEDLINE, PsycINFO, Embase, Web of Science, PsyArXiv, medRxiv, and grey literature sources were searched (1 January 2020 to 13 December 2022) using terms related to COVID-19, isolation, and adherence. Studies were included if they contained original, quantitative data of self-isolation adherence during the COVID-19 pandemic. We extracted definitions of self-isolation, measures used to quantify adherence, adherence rates, and factors associated with adherence.

RESULTS

We included 45 studies. Self-isolation was inconsistently defined. Four studies did not use self-report measures. Of 41 studies using self-report, one reported reliability; another gave indirect evidence for the lack of validity of the measure. Rates of adherence to self-isolation for studies with only some concerns of bias were 51%-86% for COVID-19 cases, 78%-94% for contacts, and 16% for people with COVID-19-like symptoms. There was little evidence that self-isolation adherence was associated with sociodemographic or psychological factors.

CONCLUSIONS

There was no consensus in defining, operationalising, or measuring self-isolation, resulting in significant risk of bias in included studies. Future definitions of self-isolation should state behaviours to be enacted and duration. People recommended to self-isolate should be given support. Public health campaigns should aim to increase perceived effectiveness of self-isolation and promote accurate information about susceptibility to infection.

Systematic review of MRI safety literature in relation to radiofrequency thermal injury prevention

INTRODUCTION

Magnetic resonance imaging (MRI) is a rapidly evolving modality, generally considered safe due to lack of ionising radiation. While MRI technology and techniques are improving, many of the safety concerns remain the same as when first established. Patient thermal injuries are the most frequently reported adverse event, accounting for 59% of MRI incidents to the Food and Drug Administration (FDA). Surveys indicate many incidents remain unreported. Patient thermal injuries are preventable and various methods for their mitigation have been published. However, recommendations can be variable, fragmented and confusing. The aim of this systematic review was to synthesise the evidence on MRI safety and associated skin injuries and offer comprehensive recommendations for radiographers to prevent skin thermal injuries.

METHODS

Four journal databases were searched for sources published January 2010-May 2023, presenting information on MRI safety and thermal injuries.

RESULTS

Of 26,801 articles returned, after careful screening and based on the eligibility criteria, only 79 articles and an additional 19 grey literature sources were included (n = 98). Included studies were examined using thematic analysis to determine if holistic recommendations can be provided to assist in preventing skin burns. This resulted in three simplified recommendations: Remove any electrically conductive items Insulate the patient to prevent any conductive loops or contact with objects Communicate regularly CONCLUSION: By implementing the above recommendations, it is estimated that 97% of skin burns could be prevented. With thermal injuries continuing to impact MRI safety, strategies to prevent skin burns and heating are essential. Assessing individual risks, rather than blanket policies, will help prevent skin thermal injuries occurring, improving patient care.

Impact of Immersive Virtual Reality on the Binocular and Accommodative Function: A Systematic Review About Literature and Its Current Limitations

The use of virtual reality (VR) is expected to increase exponentially in next years, and it is important to study whether VR can generate oculomotor, accommodative and binocular alterations in future users. Visual symptoms after the immersion inside VR have been widely reported, specifically in the case of simulator sickness, but the causes are still in study. Some authors have reported changes on accommodative and binocular parameters, but differences between studies made conclusions difficult.

PURPOSE

The aim of this study is to analyze the scientific literature about the effect of VR on the accommodative and binocular function of healthy subjects with both normal visual conditions and binocular anomalies assessing the quality of the existing studies to detect possible limitations and improve future study designs.

METHODS

A search was performed in PubMed, Web of Science and Scopus databases with the search equation (Virtual reality OR head-mounted displays) AND (accommodation OR accommodative) AND (vergence* OR convergence OR divergence OR binocular vision). A limitation was made in terms of the date of publication from 2010 onwards, identifying a total of 198 publications. Finally, 15 publications were included in the quality analysis. After a comprehensive analysis of the publications, a quality assessment was performed using a Quality Appraisal Checklist.

RESULTS

Research on effects of immersive VR on accommodative and binocular function to this date was focused on quasi-experimental pre-post studies well written and with results supporting their conclusions. Unfortunately, this scientific evidence provides heterogeneous outcomes, being the results in some cases even contradictory.

CONCLUSIONS

Information about the devices, its interpupillary distance adjustment, the software characteristics and type of task performed by users should be better controlled in future studies. Additionally, participants accommodative and binocular baseline characteristics should be better analyzed to obtain firm conclusions about the consequences of the proper immersive VR experience on visual function.

Readability of Patient Education Materials in Head and Neck Cancer: A Systematic Review

Importance

Patient education materials (PEMs) can promote patient engagement, satisfaction, and treatment adherence. The American Medical Association recommends that PEMs be developed for a sixth-grade or lower reading level. Health literacy (HL) refers to an individual's ability to seek, understand, and use health information to make appropriate decisions regarding their health. Patients with suboptimal HL may not be able to understand or act on health information and are at risk for adverse health outcomes.

Objective

To assess the readability of PEMs on head and neck cancer (HNC) and to evaluate HL among patients with HNC.

Evidence Review

A systematic review of the literature was performed by searching Cochrane, PubMed, and Scopus for peer-reviewed studies published from 1995 to 2024 using the keywords head and neck cancer, readability, health literacy, and related synonyms. Full-text studies in English that evaluated readability and/or HL measures were included. Readability assessments included the Flesch-Kincaid Grade Level (FKGL grade, 0-20, with higher grades indicating greater reading difficulty) and Flesch Reading Ease (FRE score, 1-100, with higher scores indicating easier readability), among others. Reviews, conference materials, opinion letters, and guidelines were excluded. Study quality was assessed using the Appraisal Tool for Cross-Sectional Studies.

Findings

Of the 3235 studies identified, 17 studies assessing the readability of 1124 HNC PEMs produced by professional societies, hospitals, and others were included. The mean FKGL grade ranged from 8.8 to 14.8; none of the studies reported a mean FKGL of grade 6 or lower. Eight studies assessed HL and found inadequate HL prevalence ranging from 11.9% to 47.0%.

Conclusions and Relevance

These findings indicate that more than one-third of patients with HNC demonstrate inadequate HL, yet none of the PEMs assessed were developed for a sixth grade or lower reading level, as recommended by the American Medical Association. This incongruence highlights the need to address the readability of HNC PEMs to improve patient understanding of the disease and to mitigate potential barriers to shared decision-making for patients with HNC. It is crucial to acknowledge the responsibility of health care professionals to produce and promote more effective PEMs to dismantle the potentially preventable literacy barriers.

The association between genetic factors and temporomandibular disorders: A systematic literature review

OBJECTIVE

This study aimed to investigate the correlation between genetic factors and the occurrence and progression of temporomandibular disorders (TMDs) using a comprehensive review and meta-analysis.

DESIGN

A comprehensive search was conducted using the ScienceDirect, PubMed, Cochrane Library, Dimensions, and Emerald databases. A reviewer selected the study using modified PICO criteria, considering human subjects with TMDs, comparing different genetic factors among TMD and non-TMD patients, and reporting TMD signs and symptoms as outcomes. The methodological standards of the eligible papers were assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Non-randomized Experimental Investigations. Information was collected methodically and examined.

RESULTS

The electronic database search yielded 851 articles, 19 of which were included in this study. The data analysis showed a significant influence of genetic factors, such as polymorphisms and gene differences, on the development of TMD signs and symptoms, such as myofascial pain, chronic pain, and disc displacement. In addition, gene polymorphism significantly influenced TMD development, with an odds ratio of 2.46 (1.93-3.14) and p of 0.00001.

CONCLUSIONS

Genetic factors significantly influenced TMD signs and symptoms, and genetic polymorphisms significantly influenced TMD onset and progression. Further research should be conducted in diverse settings with larger sample sizes to verify and validate these findings.

Association between language discordance and unplanned hospital readmissions or emergency department revisits: a systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Studies conflict about whether language discordance increases rates of hospital readmissions or emergency department (ED) revisits for adult and paediatric patients. The literature was systematically reviewed to investigate the association between language discordance and hospital readmission and ED revisit rates.

DATA SOURCES

Searches were performed in PubMed, Embase and Google Scholar on 21 January 2021, and updated on 27 October 2022. No date or language limits were used.

STUDY SELECTION

Articles that (1) were peer-reviewed publications; (2) contained data about patient or parental language skills and (3) included either unplanned hospital readmission or ED revisit as one of the outcomes, were screened for inclusion. Articles were excluded if: unavailable in English; contained no primary data or inaccessible in a full-text form (eg, abstract only).

DATA EXTRACTION AND SYNTHESIS

Two reviewers independently extracted data using Preferred Reporting Items for Systematic Reviews and Meta-Analyses-extension for scoping reviews guidelines. We used the Newcastle-Ottawa Scale to assess data quality. Data were pooled using DerSimonian and Laird random-effects models. We performed a meta-analysis of 18 adult studies for 28-day or 30-day hospital readmission; 7 adult studies of 30-day ED revisits and 5 paediatric studies of 72-hour or 7-day ED revisits. We also conducted a stratified analysis by whether access to interpretation services was verified/provided for the adult readmission analysis.

MAIN OUTCOMES AND MEASURES

Odds of hospital readmissions within a 28-day or 30-day period and ED revisits within a 7-day period.

RESULTS

We generated 4830 citations from all data sources, of which 49 (12 paediatric; 36 adult; 1 with both adult and paediatric) were included. In our meta-analysis, language discordant adult patients had increased odds of hospital readmissions (OR 1.11, 95% CI 1.04 to 1.18). Among the 4 studies that verified interpretation services for language discordant patient-clinician interactions, there was no difference in readmission (OR 0.90, 95% CI 0.77 to 1.05), while studies that did not specify interpretation service access/use found higher odds of readmission (OR 1.14, 95% CI 1.06 to 1.22). Adult patients with a non-dominant language preference had higher odds of ED revisits (OR 1.07, 95% CI 1.004 to 1.152) compared with adults with a dominant language preference. In 5 paediatric studies, children of parents language discordant with providers had higher odds of ED revisits at 72 hours (OR 1.12, 95% CI 1.05 to 1.19) and 7 days (OR 1.02, 95% CI 1.01 to 1.03) compared with patients whose parents had language concordant communications.

DISCUSSION

Adult patients with a non-dominant language preference have more hospital readmissions and ED revisits, and children with parents who have a non-dominant language preference have more ED revisits. Providing interpretation services may mitigate the impact of language discordance and reduce hospital readmissions among adult patients.

Climatic conditions and concentrations of BTEX compounds in atmospheric media

Climatic and meteorological conditions are among the factors affecting the ambient concentrations of BTEX compounds. This systematic review and meta-analysis aimed to interrogate the seasonal effect of climatic conditions on the concentrations of BTEX compounds. Three electronic bibliographic databases including Scopus, PubMed, and Web of Science were systematically searched up to November 14, 2023. The search algorithm followed PRISMA guidance and consisted of three groupings of keywords and their possible combinations. For various climatic conditions, the overall mean and 95% confidence interval (CI) of effect size related to BTEX concentrations were calculated using a random-effect model. In total, 104 articles were included for evaluation in this review. BTEX ambient concentration was higher in winter (ranging from 36 out of 79 relevant studies for xylene to 52 out of 97 relevant studies for benzene) followed by summer and autumn. For humidity conditions, the highest exposure values for BTEX were detected for rainy weather (ranging from 3 out of 5 relevant studies for toluene and xylene to 4 out of 5 relevant studies for benzene and ethyl benzene) compared to dry conditions. The pooled concentration (μg/m3) of benzene, toluene, ethyl benzene, and xylene were computed as 2.61, 7.12, 2.21, and 3.61 in spring, 2.13, 7.53, 1.61, and 2.75 in summer, 3.04, 9.59, 3.14, and 5.50 in autumn, and 3.56, 8.71, 2.35, and 3.91 in winter, respectively. Moreover, the pooled concentrations (μg/m3) of BTEX were measured as 2.98, 7.22, 1.90, and 3.03 in dry weather and 3.15, 6.30, 2.14, and 3.86 in rainy or wet weather, respectively. In most seasons, the ambient concentrations of BTEX were higher in countries with low and middle incomes and in Middle Eastern countries and East/Southeast Asia compared to those in other regions (P < 0.001). The increasing concentrations of BTEX in winter and autumn followed by the summer season and during rainy/wet weather appear to be reasonably consistent despite variations in study methods, quality, or geography. Therefore, it is recommended that more serious control measures are considered for decreasing exposure to BTEX in these climatic conditions.

The diagnostic accuracy of cone beam computed tomography in detecting temporomandibular joint bony disorders: a systematic review

Computed tomography (CT) has been recognized as a robust and dependable technique for delineating osseous alterations and anomalies within hard tissues. The necessity for accurate diagnosis and management of patients with temporomandibular disorders in dental practices has increasingly come to the forefront. There is ongoing scholarly debate regarding the equivalence of diagnostic outcomes yielded by cone beam computed tomography (CBCT), which offers greater accessibility in dental settings than traditional CT, in identifying bony changes within the temporomandibular joint (TMJ). Our principal aim was to conduct a systematic review of studies that compare the efficacy of CT and CBCT in the detailed assessment of bone conditions affecting the TMJ. An electronic search was conducted across databases: PubMed, Medline, Web of Science, Cochrane and Scopus. Two independent reviewers screened titles and abstracts against predefined inclusion criteria. The included articles underwent rigorous critical appraisal, during which relevant data were extracted and systematically presented in a tabular format. This systematic review incorporates 5 studies published between 2006 and 2015. In 3 studies, CBCT demonstrated comparable outcomes to CT, while 2 investigations revealed significantly enhanced accuracy for CBCT compared to CT, with reported accuracies of 0.95 ± 0.04, 0.77 ± 0.17, and 89-91% for CBCT. The aggregated evidence from the included studies indicates that CBCT offers comparable or superior accuracy in detecting osseous changes within TMJ structures. Owing to its lower radiation exposure and increased accessibility, CBCT emerges as the preferred choice over conventional CT for evaluating bony structures of the TMJ.

Community readiness and acceptance for the implementation of a novel malaria vaccine among at-risk children in sub-saharan Africa: a systematic review protocol

BACKGROUND

The World Health Organization novel malaria vaccine for at-risk children has the potential to greatly reduce the current malaria burden in sub-Saharan Africa. However, most studies have reported contradictory findings regarding community willingness for the vaccine, which could easily undermine the expected benefits of the vaccine. This study aims to ascertain the current state of community readiness and acceptance for the implementation of a novel malaria vaccine (RTS,S/ASO1) among at-risk children in sub-Saharan Africa, based on available evidence.

METHODS

This study will follow the Preferred Reporting Items for Systematic Reviews and Meta-analyses protocol (PRISMA-P) guidelines. Relevant studies will be comprehensively searched from PubMed, ScienceDirect, Web of Science, Google Scholar, and African journals online, in accordance with the Cochrane search guidelines. Two independent reviewers will screen titles, abstracts and full texts of eligible studies based on some specified eligibility criteria. When it is feasible to conduct a meta-analysis, a random effects model will be employed to estimate the common effect due to anticipated high heterogeneity of the data. The effect measure for readiness or acceptance will be reported as a pooled proportion with corresponding 95% confidence interval. Additionally, odds ratios with 95% confidence interval will be estimated to assess factors associated with readiness. These will be presented on a forest plot.

DISSEMINATION PLANS

The findings of the study will be peer-reviewed and published in a scientific journal. Conference presentations will also be made to the different stakeholders in the malaria vaccination campaigns.

Global prevalence of anxiety and depression among medical students during the COVID-19 pandemic: a systematic review and meta-analysis

PURPOSE

As future physicians, medical students have experienced tremendous pressure during the ongoing COVID-19 pandemic, which is associated with a high risk of depression and anxiety. We aimed to investigate an overview of the prevalence of anxiety and depression among medical students in various countries during the global COVID-19 pandemic, and discuss associated stressors.

METHODS

We systematically searched CINAHL, EMBASE, MEDLINE, PubMed, and Web of Science for relevant articles from December 1, 2019 to March 15, 2023. We performed meta-analysis using a random-effects model with REML method to calculate the pooled prevalence of anxiety and depression. Begg's and Egger's tests were used to identify the potential risk of publication bias. Meta-regression was used to explore potential sources of heterogeneity.

RESULTS

We identified 130 studies reporting anxiety and depression among 132,068 medical students during the COVID-19 pandemic. Eight screening tools were identified for anxiety and six for depression. The pooled prevalence of mental health outcomes for anxiety and depression was 45% (95% confidence interval [CI], 40%-49%) and 48% (95% CI, 43%-52%), respectively. The pooled prevalence of mental health outcomes for moderate and severe anxiety and moderate and severe depression was 28% (95% CI, 24%-32%) and 30% (95% CI, 26%-35%), respectively. There was high heterogeneity between studies, with I2 ranging from 99.58%-99.66%. Continent and survey date were included in the meta-regression model. The results of meta-regression revealed that medical students in Asia had a lower prevalence of anxiety, and depression than those in other regions. The survey date (from February to June, 2020) showed a significantly positive correlation with the prevalence of anxiety and depression.

CONCLUSIONS

We demonstrated the global prevalence of anxiety and depression among medical students during the COVID-19 pandemic. The data highlight that medical students worldwide are at high risk of experiencing anxiety and depression. The reported stressors can be categorized into personal, academic, environmental and cultural, and pandemic factors. Schools and institutions should ensure optimal alternative learning environments for uninterrupted provision of medical education. The appropriate authorities should prioritize the provision of adequate protection for medical students and establish policies to promote new methods of training and education during a disaster, such as via distance learning.

Natriuretic peptides and C-reactive protein in in heart failure and malnutrition: a systematic review and meta-analysis

BACKGROUND

Heart failure (HF) and malnutrition exhibit overlapping risk factors, characterized by increased levels of natriuretic peptides and an inflammatory profile. The aim of this study was to compare the differences in plasma brain natriuretic peptide (BNP), N-terminal-pro B-type natriuretic peptide (NT-proBNP), and C-reactive protein (CRP) in patients with HF and malnutrition versus normal nutrition.

METHODS

From inception until July 2023, the databases, PubMed, Scopus, Web of Science, and Cochrane Library were searched. To examine the association among malnutrition [controlling nutritional status (CONUT) score ≥2; Geriatric Nutritional Risk Index (GNRI) score <92] with BNP, NT-proBNP and CRP in patients with HF, a meta-analysis using a random-effects model was conducted (CRD42023445076).

RESULTS

A significant association of GNRI with increased levels of BNP were demonstrated [mean difference (MD): 204.99, 95% confidence interval (CI) (101.02, 308.96, I2 = 88%, P < 0.01)], albeit no statistically significant findings were shown using CONUT [MD: 158.51, 95% CI (-1.78 to 318.79, I2 = 92%, P = 0.05)]. GNRI [MD: 1885.14, 95% CI (1428.76-2341.52, I2 = 0%, P < 0.01)] and CONUT [MD: 1160.05, 95% CI (701.04-1619.07, I2 = 0%, P < 0.01)] were associated with significantly higher levels of NT-proBNP. Patients with normal GNRI scores had significantly lower levels of CRP [MD: 0.50, 95% CI (0.12-0.88, I2 = 87%, P = 0.01)] whereas significantly higher levels of CRP were observed in those with higher CONUT [MD: 0.40, 95% CI (0.08-0.72, I2 = 88%, P = 0.01)]. Employing meta-regression, age was deemed a potential moderator between CRP and GNRI.

CONCLUSIONS

Normal nutrition scores in patients with HF are linked to lower BNP, NT-proBNP, and CRP levels compared with malnourished counterparts. Despite the significant link between CRP and malnutrition, their relationship may be influenced in older groups considering the sensitivity of GNRI due to ageing factors.

Clinical Performance of Implant-Supported Prostheses in the Rehabilitation of Patients Previously Treated for Medication-Related Osteonecrosis of the Jaws (MRONJ): A Systematic Review

There is a lack of consensus on managing resultant bone and soft tissue defects or on restoring oral function and aesthetics following medication-related osteonecrosis of the jaws (MRONJ) lesion healing. This clinical challenge presents a dilemma for practitioners. Removable prostheses pose a recurrence risk if poorly fitted and may inadequately restore function or aesthetics in cases of significant bone defect. Dental implant-supported prostheses could enhance function and quality of life, though their risks and indications are not well-defined. This systematic review examines the clinical outcomes and complications associated with implant-supported rehabilitations post-MRONJ surgery. This study was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement recommendations and it was pre-registered in the Prospective Register of Systematic Reviews (PROSPERO) (CRD42023492539).

The Role of Working Memory and Short-Term Memory in Sentence Comprehension: A Systematic Review and Meta-Analysis in Probable Alzheimer's Disease

The role of either short-term memory (STM) or working memory (WM) in sentence comprehension is a matter of debate. Although it is commonly accepted that memory resources are necessary for sentence comprehension, there is no agreement regarding the nature of their role. The aim of this review is to investigate and synthesize assessment tools and correlation data between STM or WM and sentence comprehension in probable Alzheimer's disease (AD). To this aim, a systematic review and meta-analysis of the literature was conducted according to the PRISMA guidelines. PubMed, Web of Science, Scopus, PsycInfo, and LLBA databases were searched. Two independent authors selected peer-reviewed articles published in English and focused on the relationship between STM or WM and sentence comprehension in probable AD. A total of 11 case-control studies were included at the end of the selection process. Most studies adopted offline tasks to evaluate sentence comprehension, while a small number of authors applied online experimental tasks. The digit span forward and backward were the most employed standardized tests to evaluate phonological STM and WM, respectively. The meta-analysis results supported the association between performance on STM and WM and comprehension tasks. However, moderate heterogeneity was found, mainly due to the small number of included studies, especially for STM, and the substantial variability of the adopted tasks. Therefore, in order to clarify the specific source of language comprehension deficits, new and sophisticated experiments should be conducted using adequate material.

Mental Health in Elite Athletes: A Systematic Review of Suicidal Behaviour as Compared to the General Population

BACKGROUND AND OBJECTIVE

Previous systematic reviews on mental health in athletes have found athletes to be at a potentially increased risk for mental health diagnoses compared to the public. Multiple cross-sectional studies have examined suicide behaviour within different athlete populations, but there is a need for a comprehensive review to synthesize and identify risk factors and epidemiology regarding suicide behaviour in the elite athlete population, especially as it compares to the general population.

METHODS

A systematic literature search was performed in MEDLINE, EMBASE, Scopus, and Web of Science from 1990 to January 2023. Inclusion criteria included original peer-reviewed research articles examining suicidal ideation, suicide attempt, or suicide completion within elite athlete populations. Exclusion criteria included athletes participating in high-school or Paralympic level sports, studies that did not report results regarding elite athletes and non-athletes separately, and non-peer reviewed work. All studies were screened for inclusion by two independent reviewers. The primary outcome variables extracted from included studies included rates, risk factors, and protective factors for suicide behaviour. The study quality and risk of bias was evaluated for each study using the Joanna-Briggs Institute (JBI) critical appraisal tools.

RESULTS

Of the 875 unique studies identified, 22 studies, all of which were cross-sectional in nature, met the inclusion criteria. Seven studies evaluated previous athletes, 13 studies evaluated current athletes, and two studies included a combination of previous and current athletes. Seven studies involved varsity college athletes, nine involved professional athletes of various sports, and six focused on international or Olympic level athletes. The rate of suicidal ideation in professional athletes ranged from 6.9 to 18% across four studies, while the rate in collegiate athletes ranged from 3.7 to 6.5% across three studies. Ten studies compared athletes to the general population, the majority of which found athletes to be at reduced risk of suicidal ideation, suicide attempt, and suicide completion. Only one study found athletes to have increased rates of suicide compared to matched non-athletes. Risk factors for suicide behaviour identified across multiple studies included male sex, non-white race, older age, and depression. Player position, athletic level, sport played, and injuries showed trends of having limited effect on suicide behaviour risk.

CONCLUSION

This review suggests that elite athletes generally demonstrate reduced risk of suicidal ideation, suicide attempt, and suicide completion compared to the general population. Coaches should remain aware of specific factors, such as male sex, non-white race, and higher athletic level, in order to better identify at-risk athletes. Limitations of this review include the heterogeneity in the methodology and athlete populations across the included studies. Therefore, future targeted research is essential to compare suicide behaviour between sports and identify sport-specific suicide risk factors.

Long-term outcomes of converting fused hips to total hip arthroplasty are satisfactory: a systematic review and meta-analysis

Background

Although conversion arthroplasty of fused hips can relieve pain and provide patient satisfaction, long-term outcomes of total hip arthroplasty (THA) after hip fusion remain a subject of debate. This meta-analysis aimed to assess the effectiveness of THA for fused hips over a long period with concerns over potential complications.

Methods

A systematic search of five databases from 2000 until 2023 identified English studies evaluating THA for fused hips with at least 100 months of follow-up. Meta-analyses were conducted using random-effect models via the comprehensive meta-analysis software. Sensitivity analysis, in-depth meta-regression, Egger's test, and the trim-and-fill method were performed appropriately.

Results

The meta-analysis assessed 790 patients and 889 hips with a mean follow-up of 11 years. At the final follow-up, the mean Harris Hip Score (HHS) and leg length discrepancy (LLD) improved by 34.755 and 2.3 cm from the baseline, respectively. Regarding survival of hip fusion conversion to THA, most studies (88.8%) reported a 5-year implant survival rate of at least 90%, and the 15-year and 20-year implant survival rates, ranged between 80-90% and 70-90%, respectively. Subjective dissatisfaction with the conversion of hip fusion to THA was only 5.3%. Composite rates of revision, instability, and aseptic loosening were 13.6%, 3.8%, and 8.8%, respectively.

Conclusions

Conversion of fused hips to THA results in favourable long-term outcomes regarding HHS, LLD, survival rates, and subjective satisfaction, leading to improved quality of life in properly selected patients. However, the presence of complications should be considered when evaluating the overall success of the procedure.

Efficacy and Safety of Venous Sac Embolization With or Without Feeding Artery Embolization Versus Feeding Artery Embolization Alone in the Management of Pulmonary Arteriovenous Malformations: A Systematic Review and Meta-analysis

PURPOSE

To evaluate by meta-analysis the safety and efficacy of venous sac embolization (VSE) with or without feeding artery embolization versus feeding artery embolization (FAE) alone in the management of pulmonary arteriovenous malformations (PAVMs).

METHODS

This systematic review and meta-analysis was performed and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic literature search was performed in MEDLINE, Embase, and Scopus till August 31, 2021 to identify studies comparing the safety and efficacy of VSE with or without FAE versus FAE alone in PAVMs. The success of treatment was assessed by comparing the number of PAVMs with ≥70% decrease in the size of draining vein/sac between the 2 groups. The pooled odds ratio (OR) and 95% confidence interval (95% CI) were calculated using the random-effects inverse-variance model and were used to compare pooled therapeutic efficacy between the groups.

RESULTS

Three studies were found eligible for the meta-analysis. The included studies had a total of 169 patients (119 females and 50 males). The total number of PAVMs was 298, and hereditary hemorrhagic telangiectasia was present in 119 patients. The success of treatment was higher with VSE as compared to FAE (OR=3.54, 95% CI=1.66-7.56). The minor complications were similar in both groups, and one major complication occurred in the FAE group. More coils were used in the VSE group.

CONCLUSIONS

The present systematic review and meta-analysis has consolidated the evidence that VSE with or without FAE is more efficacious than FAE alone in the management of PAVMs without any increase in the associated risk of sac rupture or coil migration.

CLINICAL IMPACT

Until high-quality data from a prospective, multicentric, randomized controlled trial becomes available, the evidence consolidated by the present systematic review and meta-analysis showing the efficacy of venous sac embolization (with or without feeding artery embolization) over feeding artery embolization alone, can be used for clinical decision-making in the management of pulmonary arterio-venous malformations.

Quality of life, cognitive and behavioural impairment in people with motor neuron disease: a systematic review

PURPOSE

Motor neuron disease (MND) is a neurodegenerative disease, progressively impacting function and self-perceived quality of life (QoL). Up to 50% of people with MND can present with cognitive and behavioural impairment, with an associated increase in caregiver burden or strain. However, there has been no systematic exploration of the relationship between QoL and cognitive or behavioural impairment in MND. The aim was to determine if there is a relationship between QoL and cognitive/behavioural impairment in MND, while also supplementarily looking to determine the types of cognitive/behavioural and QoL measures utilised in these studies.

METHODS

A systematic search was performed across multiple databases (PsychINFO, Embase, Medline, AMED) for research published up to the date of February 22, 2023. Studies utilising quantitative methods of measuring QoL, cognitive/behavioural functioning/impairment were included. Findings examining relationships between QoL-cognitive/behavioural impairment were extracted and synthesised.

RESULTS

A total of 488 studies were identified, with 14 studies included in the systematic review. All 14 studies were observational (11 cross-sectional, 3 longitudinal). 13 studies utilised MND non-specific measures, particularly in relation to QoL and cognitive impairment. Of 8 studies measuring behavioural impairment 62.5% (N = 5) found either a lower QoL difference or association. Only 33.3% (N = 4) of 12 studies measuring cognitive impairment found a lower QoL difference or association.

CONCLUSIONS

This systematic review shows that behavioural impairment may have an impact on QoL in MND. There is variability in types of assessments used to measure QoL and also cognitive/behavioural impairment, most of which are disease-non-specific. Recommendations for future research are to use comprehensive disease-specific, multidomain measures to further elucidate the QoL-cognitive/behavioural impairment relationship.

Potential Therapeutic Role of Respiratory Muscle Training in Dyspnea Management of Cancer Survivors: A Narrative Review

Dyspnea is a disabling symptom presented in approximately half of all cancer survivors. From a clinical perspective, despite the availability of pharmacotherapies, evidence-based effective treatments are limited for relieving dyspnea in cancer survivors. Preliminary evidence supports the potential of respiratory muscle training to reduce dyspnea in cancer survivors, although large randomized controlled studies are warranted. The aims of this article were to review the relevant scientific literature on the potential therapeutic role of respiratory muscle training in dyspnea management of cancer survivor, and to identify possible mechanisms, strengths and limitations of the evidence as well as important gaps for future research directions.

Interventions and Hospital Characteristics Associated With Patient Experience: An Update of the Evidence

Patient experience is a key hospital quality measure. We review and characterize the literature on interventions, care and management processes, and structural characteristics associated with better inpatient experiences as measured by the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. Prior reviews identified several promising interventions. We update these previous efforts by including more recent peer-reviewed literature and expanding the review's scope to include observational studies of HCAHPS measures with process measures and structural characteristics. We used PubMed to identify U.S. English-language peer-reviewed articles published in 2017 to 2020 and focused on hospital patient experience. The two HCAHPS domains for which we found the fewest potential quality improvement interventions were Communication with Doctors and Quietness. We identified several modifiable processes that could be rigorously evaluated in the future, including electronic health record patient engagement functionality, care management processes, and nurse-to-patient ratios. We describe implications for future policy, practice, and research.

Oligella spp.: A systematic review on an uncommon urinary pathogen

BACKGROUND

Oligella is an uncommon Gram-negative coccobacillus that was first thought to belong to the urogenital tract. The genus Oligella comprises two species that were recovered from various samples worldwide.

METHODS

We perform a systematic review focusing on Oligella microbiological characteristics, habitat, role in Human microbiome and infection, and antimicrobial susceptibility.

RESULTS

In humans, Oligella is mainly found as part of the microbiome of individuals with predisposing conditions. Oligella were also associated with invasive infections in patients with underlying diseases. Nevertheless, their prevalence remains to determine. Oligella culture requires up to 48 h on agar media in vitro, while urinary samples are usually incubated for 24 h. Consequently, microbiologists should be prompt to prolong the incubation of agar media when the direct examination showed Gram-negative coccobacilli. Oligella is accurately identified using MALDI-TOF mass spectrometry, but biochemical methods often provided inconsistent results. Specific guidelines for antimicrobial susceptibility testing of Oligella lack but the incubation could require up to 48 h of incubation. In contrast to O. urethralis, which is susceptible to third-generation cephalosporin, O. ureolytica is likely resistant to numerous antimicrobials. Genectic determinants of resistance were identified for beta-lactams and aminoglycosides.

CONCLUSION

Oligella is an uncommon pathogen that can be underrecognized. Microbiologists should be prompt to prolong the incubation of agar media plated with urines when the direct examination showed Gram-negative coccobacilli. Carbapenems should probably be given for the empirical treatment.

Does insecure attachment lead to psychosis via dissociation? A systematic review of the literature

PURPOSE

Insecure attachment may constitute a vulnerability factor for psychosis, and dissociation may be a key mechanism in the development of auditory hallucinations specifically. While there is good evidence for the role of these processes in isolation, it is unclear whether dissociation accounts for the association between insecure attachment and psychosis. This systematic review takes a theory-driven approach to examine proposed causal relationships across the clinical and nonclinical literature.

METHODS

We searched five databases (PubMeD, Web of Science, PsycINFO, CINAHL and ETHOS) for published and unpublished research examining attachment, dissociation and psychosis. Two independent reviewers extracted the data and assessed the quality of all included studies.

RESULTS

We identified 242 potential articles and included 13 in the final review (2096 participants). We found that (1) disorganised attachment was consistently associated with dissociation and inconsistently associated with voices and paranoia, (2) dissociation was associated with voices and paranoia, and these links were stronger in clinical samples, and (3) dissociation played a role in the impact of insecure attachment on voice hearing and paranoia in clinical groups.

CONCLUSIONS

This is the first review to synthesise the research examining attachment, dissociation, and psychosis. The evidence is consistent with proposed causal hypotheses and raises conceptual and measurement issues, for example, the need to clarify the relative contributions of different insecure attachment styles, and utilise behavioural/observational measures to strengthen study designs. Most importantly, we need experimental and longitudinal studies to confirm causal links and targets for treatment.

Diagnosis and treatment of acute inflammatory sacroiliitis in pregnant or post-partum women: a systematic review of the current literature

The aim of the present study is to systematically review the current literature about diagnosis and treatment of acute inflammatory sacroiliitis in pregnant or post-partum women. A systematic search was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data about clinical presentation, diagnosis methods and treatment strategies were retrieved from included studies and reported in a table. After screening, five studies on 34 women were included; they were all affected by acute inflammatory sacroiliitis. Clinical examination and magnetic resonance imaging were used to confirm diagnosis. In four studies, patients were treated with ultrasound-guided sacroiliac injections of steroids and local anesthetics, while one study used only manual mobilization. Clinical scores improved in all patients. Ultrasound-guided injections proved to be a safe and effective strategy for inflammatory sacroiliitis treatment during pregnancy or post-partum.

The Cochrane risk of bias assessment tool 2 (RoB 2) versus the original RoB: A perspective on the pros and cons

Background and Aims

Critical appraisal or risk of bias assessment is a fundamental part of systematic reviews that clarifies the degree to which included research articles are qualified and reliable. Version 2 of the Cochrane tool for assessing the risk of bias in randomized trials (RoB 2), the updated version of the first tool, was released in 2019. Here, we have compared these two versions of Cochrane risk of bias assessment tools and highlighted the pros and cons of RoB 2.

Methods

Statistical analysis and methodology is not applicable to this article as no new data were created or analyzed in this study.

Results

The overall approach in RoB 2 is that by answering some signaling questions after the specification of results, effects of interest, and sources of information, an overall judgment for the quality of each study is reached. Accordingly, in the original version of the Cochrane RoB tool, the judgment can be in three different conclusions, including low, unclear, and high risk of bias. The most prominent difference in bias domains is the removal of "other bias" domain being replaced by "overall bias" judgment. Also, the most common presentation types of Cochrane risk of bias assessments are the "summary" and "graph" which are generated by Review Manager, web-based applications, or packages in R software.

Conclusion

The RoB 2 tool, compared to the original RoB, has improved and is the recommended version by the Cochrane Collaboration for quality assessment of randomized controlled trials. It is recommended to consider funding source, duration of follow-up, declaration of data availability, the status of baseline characteristics between groups, and sample size calculation methods in further revisions of the Cochrane risk of bias assessment tools.

The effects of combined transcranial direct Current stimulation with physiotherapy for physical function in subjects with knee osteoarthritis: a systematic review and meta-analysis

BACKGROUND

Transcranial Direct Current Stimulation (tDCS) emerges as a promising therapeutic intervention for knee osteoarthritis (KOA), yet its impact on physical function remains insufficiently explored.

OBJECTIVES

To evaluate the relative effects of tDCS for physical function in patients with KOA.

METHODS

Pubmed, Web of Science, Scopus and Cochrane Database were explored as of August 2023 to identify studies to be included in the current systematic review and metaanalysis. Randomized controlled trials in patients with KOA comparing tDCS with placebo were included. The outcomes defined were measures of physical function (questionnaires, gait, or physical performance). The Risk of Bias tool was used to assess bias in the randomized controlled trials, whereas the PEDro scale was applied for methodological quality, and the certainty of evidence for each outcome was assessed through GRADE. Results for each outcome were synthesized using meta-analysis (random-effects model, I2-test for heterogeneity) and a subgroup analysis was performed to improve the sensitivity of the results and to explore potential moderating factors of the effect sizes.

RESULTS

Ten studies with good to excellent quality were included, analyzing a total of 628 participants. Regarding physical function, tDCS showed a favorable effect (ES: -0.58; 95%CI -0.82, -0.33; I2: 52.1%) with a low risk of bias and low to moderate certainty of evidence. The concurrent application of physiotherapy interventions and tDCS improved the effects on pain and function. Applying physiotherapy interventions, as well as adding peripheral currents, increased the effect sizes (ES: -0.95, k = 3, p = .018; ES: -0.95, k = 4 p = .001, respectively). The pattern of application of the tDCS, either daily or in alternate days, did not moderate the effect size (p = .619). Meta-regression revealed that the number of tDCS sessions did not moderate the effect size either (p = .242).

CONCLUSION

The tDCS might be a promising therapeutic approach to enhance physical function in subjects affected with KOA. However, further systematic reviews with meta-analyses should be performed with standardized and proven-efficacy physiotherapy programs, as well as with long-term results, to ascertain whether the improvement may be sustained over time. This study provides valuable insights into optimizing tDCS interventions for enhanced outcomes in the management of KOA.Protocol available via PROSPERO [CRD42023440676].

Universal online self-help ACT interventions for youth: A systematic review

Previous reviews of online self-help have not exclusively focussed on universally delivered Acceptance and Commitment Therapy (ACT). This systematic review aimed to evaluate the effectiveness of universal online self-help ACT interventions for young people. Relevant databases were searched for studies examining ACT interventions that were delivered universally, online and as self-help (guided and unguided) to young people aged 10 to 25-years-old. Eleven studies met inclusion criteria. These were assessed for quality and findings summarised using a narrative synthesis. Outcomes on mental health, well-being and ACT processes were reviewed, and results across studies were mixed. Most studies found significant improvements in mental health and well-being outcomes following the ACT intervention; however less than half found improvements in ACT process measures. Subgroups, such as those with elevated mental health symptoms, had better outcomes. There were no changes in measures of psychological inflexibility. However, methodological issues limited the interpretation of findings. Heterogeneity between studies and methodological issues made it difficult for this review to draw conclusions regarding the effectiveness of universal online self-help ACT interventions for young people. Future research with consistent approaches is needed across these types of interventions to improve methodological rigour to determine whether these interventions are effective.

A systematic review of users experiences of using digital interventions within psychosis: a thematic synthesis of qualitative research

PURPOSE

Although the development of digital mental health support for people with psychosis has been increasing, the development and opportunities to access this have been more limited compared to other mental health conditions. Qualitative research exploring the experiences of using digital interventions amongst people with psychosis is even less well developed; however, such research is crucial in capturing the experiences of using digital interventions to ensure they are meeting the needs of people with psychosis. This paper aimed to synthesise qualitative data related to the experiences of people with psychosis who have used digital interventions.

METHODS

A systematic literature search was conducted of articles published between 1992 and October 2023 using PubMed, MBase, PsycINFO, & OVID Medline. Two reviewers independently reviewed and screened 268 papers. Papers that met inclusion criteria were quality assessed using The Critical Appraisal Skills Programme (CASP) qualitative studies checklist. The Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) checklist was used to guide the structure of the report.

RESULTS

A thematic synthesis of 19 studies revealed six overarching themes which related to different aspects and features of the digital interventions: participants' relationship with technology; the accessibility of the interventions; how the interventions could impact on individuals' awareness and management of mental health; enhanced communication and relationships; and opportunities for reflection.

CONCLUSIONS

Benefits of using digital interventions are discussed. Areas for development and improvements are highlighted. Finally, recommendations for stakeholders who develop and implement digital interventions for psychosis are made.

Association of body mass index with rapid eye movement sleep behavior disorder in Parkinson's disease

Background

The association between body mass index (BMI) and rapid eye-movement (REM) sleep-related behavioral disorder (RBD) in Parkinson's disease (PD) remains unknown. Our study was to investigate the association of BMI with RBD in PD patients.

Methods

In this cross-sectional study, a total of 1,115 PD participants were enrolled from Parkinson's Progression Markers Initiative (PPMI) database. BMI was calculated as weight divided by height squared. RBD was defined as the RBD questionnaire (RBDSQ) score with the cutoff of 5 or more assessed. Univariable and multivariable logistic regression models were performed to examine the associations between BMI and the prevalence of RBD. Non-linear correlations were explored with use of restricted cubic spline (RCS) analysis. And the inflection point was determined by the two-line piecewise linear models.

Results

We identified 426 (38.2%) RBD. The proportion of underweight, normal, overweight and obese was 2.61, 36.59, 40.36, and 20.44%, respectively. In the multivariate logistic regression model with full adjustment for confounding variables, obese individuals had an odds ratio of 1.77 (95% confidence interval: 1.21 to 2.59) with RBD compared with those of normal weight. In the RCS models with three knots, BMI showed a non-linear association with RBD. The turning points of BMI estimated from piecewise linear models were of 28.16 kg/m2, 28.10 kg/m2, and 28.23 kg/m2 derived from univariable and multivariable adjusted logistic regression models. The effect modification by depression on the association between BMI and RBD in PD was also found in this study. Furthermore, the sensitivity analyses linked with cognition, education, and ethnic groups indicated the robustness of our results.

Conclusion

The current study found a significant dose-response association between BMI and RBD with a depression-based difference in the impact of BMI on RBD in PD patients.

Use of digital media by adolescents for sexual and reproductive health and rights communication in sub-Saharan Africa: a protocol for systematic review

BACKGROUND

Within the sub-Saharan African region, there is a growing concern for sexual and reproductive health and rights communication, and more particularly, for adolescents. Given the existing barriers associated with face-to-face access, the need to use digital media to access information and services has become desirable and imperative, especially so due to the COVID-19 pandemic. However, in sub-Saharan Africa, a synthesis of evidence that informs adolescents' digital media engagements for sexual and reproductive health and rights (SRHR) communication is limited. This systematic review therefore aims to examine and synthesize evidence on use of digital media for sexual and reproductive health and rights communication by adolescents in sub-Saharan Africa.

METHODS

A search for peer-reviewed articles will be conducted in PubMed, ScienceDirect, Scopus, Embase, Web of Science, PsychINFO and Google Scholar with emphasis on those published between 2000 and 2023. Only observational and qualitative studies will be included. Quality assessment of included articles will be done using standardized checklists from the Joanna Briggs Institute. Both descriptive and narrative summaries will be used to appraise evidence from included studies.

DISCUSSION

This review will be essential in providing information on the types of digital media adolescents use, the various SRHR issues they use this platform to address and their reasons for using it and associated challenges. It will also contribute to the advocacy for the inclusion of these technologies in the teaching and learning, provision of and access to SRHR information and services by teachers, public health providers and peer educators in the subregion.

Association between clinical biomechanical metrics of cervical spine function and pain or disability in people with neuromusculoskeletal neck pain: Protocol for a systematic review and planned meta-analysis

INTRODUCTION/BACKGROUND

Neck pain is a burdensome condition associated with pain, disability, and economic cost. Neck pain has been associated with observable changes in neuromuscular function and biomechanics. Prior research shows impairments in kinematic control, including reduced mobility, velocity, and smoothness of cervical motion. However, the strength of association between these impairments and patient-reported pain and disability is unclear rendering development of novel and relevant rehabilitation strategies difficult. The aim of this systematic review is to synthesize existing evidence on the strength of association between clinical biomechanical metrics of neck function (ROM, strength, acceleration, accuracy, smoothness, etc.) and patient-reported neck pain and disability.

METHODS/ANALYSIS

This protocol follows Cochrane guidelines and adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P). MEDLINE, EMBASE, CINAHL, SPORTDiscus, Web of Science and Scopus will be searched, along with the gray literature, up to 20 November 2023, using terms and keywords derived from initial scoping searches. Observational studies, including cohorts and cross-sectional studies, that explore associations between clinical biomechanics of the neck and patient-reported outcomes of neck pain or disability will be included. Two reviewers will independently perform study selection, data extraction, and risk of bias assessment (National Institute of Health tool). Data will be synthesized using either a random effects meta-analytic approach or qualitatively using a modified Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, dependent on the homogeneity of data available.

DISCUSSION AND RELEVANCE

This review addresses a gap in the literature by systematically synthesizing findings on the relationship between neck function impairments and patient-reported outcomes. It will identify priorities for neck pain rehabilitation and gaps in current knowledge.

DISSEMINATION

The results of this review will be disseminated through a peer-reviewed publication, conference presentation, and lay language summaries posted on an open-access website.

Proportions and determinants of successful surgical repair of obstetric fistula in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Obstetric fistula is a serious and debilitating problem resulting from tissue necrosis on the reproductive and urinary and/or lower gastrointestinal tract organs due to prolonged labor. Primary studies of the treatment of obstetric fistulae report significantly variable treatment outcomes following surgical repair. However, no systematic review and meta-analysis has yet estimated the pooled proportion and identified the determinants of successful obstetric fistula surgical repair.

OBJECTIVE

To estimate the proportion and identify the determinants of successful surgical repair of obstetric fistulae in low- and middle-income countries.

METHODS

The protocol was developed and registered at the International Prospective Register of Systematic Reviews (ID CRD42022323630). Searches of PubMed, Embase, CINAHL, Scopus databases, and gray literature sources were performed. All the accessed studies were selected with Covidence, and the quality of the studies was examined. Finally, the data were extracted using Excel and analyzed with R software.

RESULTS

This review included 79 studies out of 9337 following the screening process. The analysis reveals that 77.85% (95%CI: 75.14%; 80.56%) of surgical repairs in low and middle-income countries are successful. Women who attain primary education and above, are married, and have alive neonatal outcomes are more likely to have successful repair outcomes. In contrast, women with female genital mutilation, primiparity, a large fistula size, a fistula classification of II and above, urethral damage, vaginal scarring, a circumferential defect, multiple fistulae, prior repair and postoperative complications are less likely to have successful repair outcomes.

CONCLUSION

The proportion of successful surgical repairs of obstetric fistula in low and middle-income countries remains suboptimal. Hence, stakeholders and policymakers must design and implement policies promoting women's education. In addition, fistula care providers need to reach and manage obstetric fistula cases early before complications, like vaginal fibrosis, occur.

Burden of Antimicrobial Resistance in Japan: A Systematic Literature Review and Meta-Analysis

INTRODUCTION

Antimicrobial resistance (AMR) is one of the most serious public health challenges worldwide, including in Japan. However, there is limited evidence assessing the AMR burden in Japan. Thus, this systematic literature review (SLR) and meta-analysis (MA) were conducted to assess the clinical and economic burden of AMR in Japan.

METHODS

Comprehensive literature searches were performed on EMBASE, MEDLINE, the Cochrane Library, and ICHUSHI between 2012 and 2022 following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. MA estimated a pooled effect between the two comparative arms (AMR vs. non-AMR). The results were reported in measures of odds ratios (ORs) for in-hospital mortality and in standardized mean differences (SMDs) for length of stay (LOS) and direct medical costs.

RESULTS

Literature searches identified 1256 de-duplicated records, of which 56 observational studies (English, n = 35; Japanese, n = 21) were included. Of note, twenty-two studies (39.3%) compared the AMR group with non-AMR group. In the SLR, in-hospital mortality, LOS, and direct medical costs were higher in the AMR group compared to the non-AMR group. Eight studies were selected for the MA. In the AMR group, the pooled estimate showed a statistically higher in-hospital mortality [random effect (RE)-OR 2.25, 95% CI 1.34-3.79; I2 = 89%; τ2 = 0.2257, p < 0.01], LOS (RE-SMD 0.37, 95% CI  - 0.09-0.84; I2 = 99%; τ2 = 0.3600, p < 0.01), and direct medical cost (RE-SMD 0.53, 95% CI 0.43-0.62; I2 = 0.0%; τ2 = 0.0, p = 0.88) versus the non-AMR group.

CONCLUSION

Our study presents an overview of the clinical and economic burden of AMR in Japan. Patients with AMR infections experience significantly higher in-hospital mortality, LOS, and direct medical costs compared with patients without AMR infections.

Use of Biosimilars: A Systematic Review of Published Position Statements and Recommendations from Health Organisations and Societies

BACKGROUND

Hesitation about using biosimilars still exists among healthcare professionals (HCPs), despite extensive experience with their use. Globally, several health organisations and societies from various specialties have issued biosimilar position statements to guide the use of biosimilars in their specialties. However, it is uncertain how similar or different their positions or recommendations are or whether these positions have evolved with the increased experience and availability of new evidence.

OBJECTIVES

The study aimed to describe and assess the recommendations of published position statements regarding several aspects of biosimilars across specialties and determine whether these positions have changed with the emergence of new evidence.

METHODS

We systematically searched for published position statements of biosimilars in online databases and included statements written in English. The search was from the inception of the databases until May 2023. Two reviewers independently extracted the data. Only position statements that included recommendations to guide the use of biosimilars in clinical practice and were issued by health organisations and societies, including expert panels, were included. We synthesised recommendations on five aspects: prescribing practice, extrapolation of indication, interchangeability, treatment initiation with biosimilars in biologic-naïve patients, and pharmacovigilance.

RESULTS

The review included 25 papers involving eight specialties, 16 of which were from European countries, 1 from an international organisation representing 49 countries, and 6 from various countries. The papers were published between 2009 and 2020, with 19 published between 2015 and 2020. Of the five aspects of biosimilars assessed, nearly half (11 of 25) of the papers at the time they were published did not base their positions on a scientific or evidence-based approach. Only 4 of the 25 position papers were identified as revisions of their previous papers. With increasing experience in biosimilars and the emergence of new evidence, about 60% (16 of 25) of the papers contained outdated recommendations, particularly on two aspects. They were extrapolations of indications and interchangeability (including switching). The recommendations for most papers for three other aspects were still appropriate. These were prescribing biosimilars by their brand name and active ingredient, initiating treatment with biosimilars in biologic-naïve patients, and monitoring the long-term safety of biosimilars through pharmacovigilance. For four of the revised papers, their position evolved from opposing indication extrapolation for biosimilars to accepting it, while the position of two papers shifted from not recommending biosimilar switching to permitting the practice. Meanwhile, most papers were against automatic substitution by pharmacists because the evidence for this practice was still limited.

CONCLUSIONS

Across specialties, the variability among the position statements is seen for extrapolation of indications for biosimilars and interchangeability (including switching). This requires a revision, considering the latest evidence and growing experience with the use of biosimilars in extrapolated indications and with switching.

Association of future cancer metastases with fibroblast activation protein-α: a systematic review and meta-analysis

Introduction

Fibroblast activation protein-α (FAP-α) is a vital surface marker of cancer-associated fibroblasts, and its high expression is associated with a higher tumor grade and metastasis. A systematic review and a meta-analysis were performed to associate future metastasis with FAP-α expression in cancer.

Methods

In our meta-analysis, relevant studies published before 20 February 2024 were systematically searched through online databases that included PubMed, Scopus, and Web of Science. The association between FAP-α expression and metastasis, including distant metastasis, lymph node metastasis, blood vessel invasion, vascular invasion, and neural invasion, was evaluated. A pooled odds ratio (OR) with 95% confidence intervals (CI) was reported as the measure of association.

Results

A total of 28meta-analysis. The random-effects model for five parameters showed that a high FAP-α expression was associated with blood vessel invasion (OR: 3.04, 95% CI: 1.54-5.99, I 2 = 63%, P = 0.001), lymphovascular invasion (OR: 3.56, 95% CI: 2.14-5.93, I 2 = 0.00%, P < 0.001), lymph node metastasis (OR: 2.73, 95% CI: 1.96-3.81, I 2 = 65%, P < 0.001), and distant metastasis (OR: 2.59; 95% CI: 1.16-5.79, I 2 = 81%, P < 0.001). However, our analysis showed no statistically significant association between high FAP-α expression and neural invasion (OR: 1.57, 95% CI: 0.84-2.93, I 2 = 38%, P = 0.161).

Conclusions

This meta-analysis indicated that cancer cells with a high FAP-α expression have a higher risk of metastasis than those with a low FAP-α expression. These findings support the potential importance of FAP-α as a biomarker for cancer metastasis prediction.

Role of microRNAs in Diabetes-Associated Periodontitis: A Scoping Review

Aim

Diabetes mellitus (DM), a metabolic disorder, exhibits a bidirectional relationship with periodontitis (PD), and recently, microRNAs (miRNAs) were associated with their progression. This review aims to assess the role of miRNAs in the pathogenesis of DM-associated PD and their plausible application as a biomarker for PD in individuals with DM.

Materials and Methods

The search conducted until September 2023 on Medline (Pubmed), Scopus, Embase, and Web of Science using the keywords "microRNA," "miRNA," or "miR," combined with "Diabetes" and "PD" yielded 100 articles. Only research focusing on the role of miRNAs in the pathogenesis of DM-associated PD and their potential application as biomarkers for both conditions were included. Finally, 14 studies were assessed for any bias, and the collected data included study design, sample size, participant groups, age, sample obtained, PD severity, miRNAs examined, clinical and biochemical parameters related to DM and PD, and primary outcomes.

Results

In vivo studies indicated altered expression of miRNAs-146a, -146b, -155, -200b, -203, and -223, specifically in the comorbid subjects with both conditions. Animal, ex vivo, and in vitro studies demonstrated altered expression of miRNAs-126, -147, -31, -25-3p, -508-3p, -214, 124-3p, -221, -222, and the SIRT6-miR-216/217 axis. These miRNAs impact innate and adaptive immune mechanisms, oxidative stress, hyperglycemia, and insulin sensitivity, thereby promoting periodontal destruction in DM. miRNA-146a emerges as a reliable biomarker of PD in DM, whereas miRNA-155 is a consistent predictor of PD in subjects without DM.

Conclusions

miRNAs exert influence on immuno-inflammation in DM-associated PD. Although they can be biomarkers of PD and DM, their clinical utility is hindered by the absence of standardized tests to evaluate their sensitivity and specificity. Moreover, there has been limited exploration of the role of miRNAs in DM-associated PD through human studies. Future clinical trials are warranted to address this gap, focusing on standardizing sample collection, miRNA sources, and detection methods. This approach will enable the identification of specific miRNAs for DM-associated PD.

Covid-19 hotlines, helplines and call centers: a systematic review of characteristics, challenges and lessons learned

BACKGROUND

During the Covid-19 pandemic, a number of hotlines/helplines/call centers was implemented to provide remote services and support public health. The objective of this study was to investigate the characteristics, challenges and lessons learned of implementing Covid-19 hotlines/helplines/call centers during the pandemic.

METHODS

PubMed, Web of Science, Scopus, the Cochrane Library, IEEE Xplore, and ProQuest databases as well as Google Scholar were searched between 1st January 2020 and 31st December 2023 to retrieve relevant articles published in English. The quality and risk of bias of the studies were assessed using the Appraisal tool for Cross-Sectional Studies (AXIS), the Mixed Methods Appraisal Tool (MMAT), and Critical Appraisal Skills Programme (CASP) Checklist.

RESULTS

In total, 43 out of 1440 articles were included in this study. About half of the hotlines/helplines/call centers were launched in March 2020 (n = 19). Providing psychological support (n = 23), reliable information about Covid-19 (n = 10), healthcare advices about Covid-19 (n = 8), and triage (n = 7) were the most common purposes of implementing these services. The most common challenges included a lack of physical examination, unavailability of hotlines/helplines/call centers at the point of need, and delay in updating Covid-19 information. The most common lessons learned were employing qualified staff, providing proper training, and getting feedback from the callers and operators.

CONCLUSION

According to the results, most of the Covid-19 hotlines/helplines/call centers were launched in the early months of the pandemic, and about half of them were active seven days a week. Most of the operators were mental health providers and clinicians. The findings show the importance of continuous psychological support during crises, particularly when adequate information about the situation is not available. The challenges experienced by the callers and operators as well as the lessons learned by the service providers also need to be considered for future crises to increase the effectiveness of similar services.

Prevalence of Complex Post-Traumatic Stress Disorder in Serving Military and Veteran Populations: A Systematic Review

Serving military personnel and veterans are known to be at elevated risk of post-traumatic stress disorder (PTSD), and some veterans have been shown to respond poorly to current standard treatments. Evidence so far suggests that according to the 11th edition of the International Classification of Diseases and Related Health Problems guidelines, complex PTSD (CPTSD) may be of higher prevalence in the general population than PTSD. The aim of the study was to investigate the prevalence of CPTSD compared to PTSD in serving and ex-serving military populations. A systematic review was conducted with the search criteria set to peer-reviewed English language journal articles, focusing on serving military or veteran populations, reporting on the prevalence of CPTSD, not restricted by year. Four comprehensive databases (Psycinfo, Pubmed, CINAHL, and Embase) were searched. Of the 297 identified articles, 16 primary studies were eligible for inclusion. The review was registered in the PROSPERO database (CRD42023416458), and results were reported based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Of the 16 studies, 13 demonstrated higher prevalence of CPTSD than PTSD. Studies were predominantly veteran focused. Prevalence of CPTSD ranged from 5% to 80.63%, while prevalence of PTSD ranged from 3.8% to 42.37%. There was high heterogeneity in study populations, preventing meta-analysis. This is the first systematic review to assess the prevalence of CPTSD in serving military and veteran populations, with the findings demonstrating a higher rate of CPTSD compared to PTSD. It is hoped that the review will assist clinicians and military and veteran health services with appropriate assessment, diagnosis, and intervention for those affected by CPTSD, as well as PTSD.

Optimizing Recovery: A Systematic Scoping Review of Upper Extremity Exercise Immediately after Cardiac Implantable Electronic Device Implantation

INTRODUCTION

Cardiac implantable electronic devices (CIEDs), including pacemakers, defibrillators, and resynchronization devices, significantly enhance patient outcomes, reduce sudden cardiac death, and improve health-related quality of life. CIED implantation is associated to persistent shoulder dysfunction in a considerable number of patients one-year post-implantation. This may result in disability, diminished quality of life, work absenteeism, and negative psychological effects. Restoring upper extremity function after CIED implantation should be a standard of cardiovascular care. Our systematic scoping review aimed to summarize available evidence, addressing vital questions about safety, effectiveness, exercise type, and time of exercise initiation immediately after CIED implantation.

METHODS

We conducted a comprehensive literature search in 5 electronic databases for original research in English, and a manual search on the references of included studies. We used Rayyan web application for study selection, and PRISMA-ScR to conduct and report the review. We assessed methodological quality using the Cochrane Risk of Bias Assessment Tool and Joanna Briggs Institute critical appraisal checklists.

RESULTS

This review included 6 studies that used upper extremity pendular, range of motion, stretching and strengthening exercises. Initiation time varied from the first postoperative day to the second postoperative week. All studies showed significant association between active upper extremity exercise and reduced dysfunction and disability after CIED implantation. There were no significant differences in complication rates between control and experimental groups.

CONCLUSION

A limited number of low-to-average quality studies suggest active upper extremity exercise immediately after CIED implantation is safe, effective at reducing dysfunction, and improves quality of life. Higher-quality studies are needed to validate these findings.

Protocol for a systematic review and meta-analysis of the prevalence of mental illness among nursing home residents

BACKGROUND

There is a high prevalence of mental illness in nursing home residents compared to older adults living in the community. This was highlighted in the most recent comprehensive systematic review on the topic, published in 2010. In the context of a rapidly aging population and increased numbers of older adults requiring residential care, this study aims to provide a contemporary account of the prevalence of mental illness among nursing home residents.

METHODS

This protocol was prepared in line with the PRISMA-P 2015 Statement. Systematic searches will be undertaken across six electronic databases: PubMed, Embase, Web of Science, PsycNET, CINAHL, and Abstracts in Social Gerontology. Peer-reviewed studies published from 2009 onwards which report the prevalence of mental illness within nursing home populations will be included. Database searches will be supplemented by forward and backward citation searching. Titles and abstracts of records will be screened using a semi-automated process. The full text of selected records will be assessed to confirm inclusion criteria are met. Study selection will be recorded in a PRISMA flowchart. A pilot-tested form will be used to extract data from included studies, alongside the JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data. A study characteristics and results table will be prepared to present key details from each included study, supported by a narrative synthesis. Random-effects restricted maximum likelihood meta-analyses will be performed to compute pooled prevalence estimates for mental illnesses represented in the identified studies. Heterogeneity will be assessed using Cochran's Q and Higgins' I2 statistics. A Funnel plot and Egger's test will be used to assess publication bias. The GRADE approach will be used to assess the quality of the body of evidence identified.

DISCUSSION

The study will provide a comprehensive and contemporary account of the prevalence of mental illness among nursing home residents. Meta-analyses will provide robust prevalence estimates across a range of presentations. Key insights will be highlighted, including potential sources of heterogeneity. Implications for residents, researchers, care providers, and policymakers will be noted.

Association of vitamin D and cognition in people with type 2 diabetes: a systematic review

CONTEXT

There is a high prevalence of vitamin D deficiency and impaired cognitive function in people with type 2 diabetes mellitus (T2DM).

OBJECTIVE

To critically and systematically review the literature on the association between vitamin D status and cognitive performance in people with type 2 diabetes.

DATA SOURCES

This review was conducted according to PRISMA recommendations. MEDLINE, SCOPUS, the Cochrane Library, and Web of Science databases were searched using the terms "Diabetes Mellitus, Type 2", "Cognitive Function", and "Vitamin D".

DATA EXTRACTION

Eight observational and 1 randomized study were included, containing data of 14 648 adult and elderly individuals (19-74 y). All extracted data were compiled, compared, and critically analyzed.

DATA ANALYSIS

There is no strong evidence that lower serum concentrations of vitamin D and vitamin D-binding protein are associated with worsening cognitive function in individuals with T2DM. Vitamin D supplementation (12 wk) improved the scores of some executive functioning tests, although there was no difference between low doses (5000 IU/wk) and high doses (50 000 IU/wk).

CONCLUSIONS

There is no high-quality evidence demonstrating an association between vitamin D status and cognitive function, or clinical benefits on cognition from vitamin D supplementation in individuals with T2DM. Future studies are needed. Systematic Review Registration: PROSPERO registration no. CRD42021261520.

Emotional and relational problems of adolescents with and without a migrant background in Europe: a systematic review

Mental health of migrant adolescents is a topic that has been widely studied in the past decades. Emotional and behavioural problems are amongst the most explored areas; however, little attention has been paid to the relational sphere, which represents another key aspect of mental health and is paramount during adolescence. This systematic review analysed the available evidence on emotional and relational problems comparing adolescents with and without a migrant background in Europe between 2010 and 2021. The search was conducted in four databases using a common search strategy composed of terms addressing adolescence, migrant population, and emotional and relational problems. Three rounds of screening produced 36 eligible studies. Factors affecting both types of problems were identified and categorised using thematic synthesis, dividing them into factors affecting both types of problems jointly or separately and analysing them according to three systemic levels affecting the adolescents' lives (intrapersonal, interpersonal and external). Critical analysis of the results pointed to mixed findings, with a mild tendency in migrant-background adolescents to portray more emotional problems than their native peers and a stronger tendency for relational problems in the same direction. Several limitations were identified and, along with the conclusions, point to suggestions for future research focusing on studying relational problems as a key component of mental health and its link to emotional problems. Further suggestions entail designing studies that target adolescents with different migrant-background profiles and cultural origins to establish differences between them and identify additional factors affecting emotional and relational problems during the pre-migration and transit phases of the migratory journey to help prevent the onset of these problems.

Immunogenicity and Safety of the Three-Dose COVID-19 Vaccine Regimen in Patients Receiving Renal Replacement Therapy: A Systematic Review and Meta-Analysis

Background

A three-dose regimen is the current standard for COVID-19 vaccination, but systematic data on immunogenicity and safety in chronic kidney disease patients remains limited.

Objectives

We conducted a meta-analysis on the immunogenicity and safety of three-dose COVID-19 vaccination in patients on renal replacement therapy (RRT).

Methods

Systematic literature search in four electronic databases yielded twenty eligible studies (2,117 patients, 94% of whom received mRNA vaccines) for meta-analysis.

Results

The overall seropositivity rate of anti-SARS-CoV-2 was 74.2% (95% CI: 65.0-83.4%) after three-dose COVID-19 vaccination. The seropositivity rate of anti-SARS-CoV-2 in kidney transplant recipients (KTRs) was 64.6% (95% CI: 58.7-70.5%), and 43.5% (95% CI: 38.5-48.6%) of non-responders after second dose became seropositive after third dose. The seropositivity rate of anti-SARS-CoV-2 was 92.9% (95% CI: 89.5-96.2%) in dialysis patients, and 64.6% (95% CI: 46.8-82.3%) of non-responders after second dose became seropositive after third dose. In KTRs, each year increase in transplant vintage was associated with 35.6% increase in anti-SARS-CoV-2 seropositivity (95% CI: 15.9-55.4%, p = 0.01). There were no serious adverse events attributed to vaccination in KTRs, and the commonest local and systemic adverse events were injection site pain and fatigue, respectively.

Conclusion

Three-dose COVID-19 vaccination regimen in patients on RRT is associated with reduced immunogenicity, especially in KTRs. There are no adverse events associated with third-dose COVID-19 vaccine in KTRs.

Personality traits and pre-treatment beliefs and cognitions predicting patient adherence to continuous positive airway pressure: A systematic review

Adherence to Continuous Positive Airway Pressure (CPAP) for obstructive sleep apnoea (OSA) can be improved by behavioural interventions which modify patients' beliefs and cognitions about OSA, CPAP, and themselves. We have conducted the first systematic review of the literature on beliefs and cognitions held before starting treatment, and personality (which influences the former) that predict the decision to purchase or start CPAP, or CPAP adherence one month or more after CPAP initiation. A systematic search and screen of articles identified 21 eligible publications from an initial 1317. Quality assessment performed using an adapted Newcastle-Ottawa Scale demonstrated that 13 (62%) studies were poor quality and only seven (33%) were high quality. Eighteen factors, such as self-efficacy (confidence) in using CPAP and value placed on health predicted CPAP adherence; however, for only six (33%), utility as an intervention target is known, from calculation of individual predictive power. Studies did not use new behavioural frameworks effective at explaining adherence behaviours, nor did they interview patients to collect in-depth data on barriers and facilitators of CPAP use. Future studies cannot have these limitations if high quality evidence is to be generated for intervention development, which is currently sparse as highlighted by this review.
