Impact of Chinese herbal medicine on sarcopenia in enhancing muscle mass, strength, and function: A systematic review and meta-analysis of randomized controlled trials

Sarcopenia has become important to the public health with the increase in the aging population in society. However, the therapeutic effects of conventional approaches, including pharmacotherapy, exercise, and nutritional intervention, are far from satisfactory. Chinese herbal medicine is a new treatment format with interesting possibilities in sarcopenia has been widely practiced. The study aims to explore the effectiveness of Chinese herbal medicine in sarcopenia. We comprehensively searched the following electronic databases: Medline, EMBASE, APA PsycInfo, Cochrane Library, Web of Science, PubMed, and Chinese database from the establishment of the database to December 2022 (no language restrictions). Randomized controlled clinical studies on the use of Chinese herbal medicine in sarcopenia were selected in compliance with PRISMA guidelines. Review Manager and Stata were used for statistical analysis and the mean difference and standardized mean difference were adopted. Of 277 identified studies, 17 were eligible and included in our analysis (N = 1440 participants). The results showed that Chinese herbal medicine can improve total efficiency (RR = 1.29, 95% CI [1.21, 1.36], p < 0.00001) in sarcopenia and enhance muscle mass (SMD = 1.02, 95% CI [0.55, 1.50], p < 0.0001), and muscle strength measured by grip strength (SMD = 0.66, 95% CI [0.36, 0.96], p < 0.0001), measured by 60°/s knee extension peak TQ (MD = 5.63, 95% CI [-0.30, 11.57], p = 0.06) and muscle function measured by 6-meter walking speed (SMD = 1.34, 95% CI [0.60, 2.08], p = 0.0004), measured by the short physical performance battery of 1.50%, 95% CI (1.05, 1.95), measured by the EuroQoL 5-dimension of (SMD = 0.27, 95% CI [-0.10, 0.65], p = 0.16), suggesting that Chinese herbal medicine alone or combined with conventional treatment has ameliorating effect on sarcopenia. Chinese herbal medicine is a potential therapeutic strategy in sarcopenia. The funnel plot and Egger's test indicated publication bias. To confirm our conclusions, further high-quality studies should be conducted.

The experiences of having a sibling with an eating disorder: A systematic review of the literature

OBJECTIVE

Research on carers in the context of eating disorders (EDs) has predominantly focused on parents and offspring, overlooking the adverse effects EDs have on the lives of siblings. This study aims to shift the paradigm by reviewing the literature in this area. To the authors' knowledge, this is the first review of the literature that broadly captured the lived experiences of siblings without being limited by specific search terms such as coping strategies and levels of psychopathology.

METHOD

Six databases (ERIC, MEDLINE, PsycInfo, Pubmed, Scopus, and Web of Science) were searched using predetermined search strings. Quantitative, qualitative, and mixed methods studies were included as long as they were focused on siblings' experiences of having a brother or sister with an ED. No publication date restrictions were applied, and thorough quality assessments were initially carried out before a qualitative analysis of the data was conducted.

RESULTS

Twenty-one studies were eligible for inclusion, thematic synthesis yielded six core themes, and 17 subthemes related to the inter- and intrapersonal impacts of the ED on siblings' lives. These themes and sub-themes include fragmentation in family relationships, parentification, and competition and jealousy.

CONCLUSION

It is of utmost importance to gain a better understanding of siblings' experiences and needs in relation to EDs. The findings are discussed in relation to the existing literature and theoretical and clinical implications, for example, tailored approaches accounting for siblings' experiences.

Global air pollution exposure and congenital anomalies: an updated systematic review and meta-analysis of epidemiological studies

A systematic review and meta-analysis was conducted to evaluate recent epidemiological evidence on the association of air pollution with congenital anomalies (CAs). Of 11,014 records, 49 were finally included in this meta-analysis. Per 10 μg/m3 increase in air pollutant, PM10 exposure during the 1st month of pregnancy and at the first trimester (T1) was associated with increased overall CAs. Further, exposure to PM10 was associated with congenital heart disease (OR = 1.055, 95% CI: 1.035, 1.074) and patent ductus arteriosus (OR = 1.094, 95% CI: 1.020, 1.168) at T1, with chromosomal anomalies during the entire pregnancy and with nervous system anomalies when exposure occurred 3 months prior to pregnancy, during the 1st, 2nd months of pregnancy and at T1. Besides, a significant association with overall CAs was observed for a combined exposure of PM10 and SO2 during the 1st month of gestation (OR: 1.101, 95% CI: 1.023, 1.180). A combined exposure of PM10 and CO was also associated with tetralogy of Fallot during 3-8 weeks of gestation (OR: 1.016, 95% CI: 1.005, 1.027). No significant associations were observed between PM2.5, NO2, and O3 exposure and CAs.

Effectiveness of family centred interventions for family caregivers: A systematic review and meta-analysis of randomized controlled trials

AIMS AND OBJECTIVES

To examine the effectiveness of family-centred interventions among family caregivers.

BACKGROUND

Family-centred interventions are an emerging form of intervention that can be effective at improving physical and mental health outcomes for patients and family caregivers. To date, no reviews have examined the effectiveness of family-centred interventions for family caregivers.

DESIGN

A systematic review, including a meta-analysis, was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA 2020) checklist.

METHODS

Seven English and two Chinese electronic databases were compressively searched from the outset to March 2023. Two researchers independently reviewed the abstracts and full texts, extracted the data and assessed the risk of bias independently by using the Cochrane 'Risk of bias assessment tool'.

RESULTS

This systematic review and meta-analysis included 20 articles. The results of the meta-analysis showed that family-centred interventions could significantly improve caregiver burden (p=0.003), quality of life (p = 0.007), depression (p = 0.0002), and stress (p < 0.0001) but not anxiety or family functioning. According to our subgroup analysis, the family-centred empowerment model (p = 0.009) was superior to the other family intervention (p=0.004) in reducing caregiver burden. Family-centred interventions are more effective at reducing the burden of caregiving on family caregivers of adolescent patients (SMD=-0.79, 95% CI[-1.22,-0.36], p = 0.0003) than on adult patients (SMD=-0.37, 95% CI [-0.61,-0.12], p = 0.004).

CONCLUSIONS

Family-centred interventions could enhance family caregivers' burden, quality of life, stress and depression but had no significant impact on anxiety or family functioning.

RELEVANCE TO CLINICAL PRACTICE

Family-centred interventions have the potential to improve the health status and caregiving burden of family caregivers. Rigorous and high-quality evidence is needed to confirm the long-term effects of these interventions on family caregivers.

TRIAL REGISTRATION DETAILS

The protocol has been registered in the PROSPERO international prospective register of systematic reviews (Protocol registration ID: CRD42023453607).

Effectiveness of interventions for school-aged-children and adolescents with fetal alcohol spectrum disorder: a systematic review and meta-analysis

PURPOSE

To describe allied health and educational interventions and their effectiveness for children and adolescents with fetal alcohol spectrum disorder (FASD). To appraise the quality and strength of studies.

METHODS

Electronic databases were searched between 2005 and March 2022, identifying non-pharmacological studies supporting function, activity, or participation for FASD participants aged 5-18 years using any quantitative research design. Outcomes were coded using International Classification of Functioning, Disability and Health, family of Participation Related Constructs and behaviour categories. Multi-level random-effects meta-analysis examined intervention effects. Study methodological quality was evaluated using Cochrane risk of bias tools, RoBiNT, AMSTAR 2 and NHMRC Hierarchy levels of evidence. Certainty of findings were synthesised using GRADE approach.

RESULTS

The systematic review included 25 studies with 735 participants, 10 of which were analysed by meta-analysis. Body function and structure, activity, behaviour, and sense of self outcomes were pooled. A small, positive effect favouring interventions was found (g = 0.29, 95% CI = 0.15-0.43), however the GRADE certainty was rated as low. No participation outcomes were identified.

CONCLUSIONS

Some interventions targeting body function and structure, activity and behaviour outcomes were effective. Evidence of interventions that support children's and adolescent's participation as an outcome is lacking.

A Systemic Review of the Difference Between Diets for Preterm Infants Containing Raw Mother's Own Milk and Frozen or Pasteurized Mother's Own Milk

BACKGROUND

Raw, never stored or pasteurized mother's own milk (MOM) is not always available to feed preterm infants; however, storage and pasteurization of MOM diminishes some bioactive components. It can be difficult to feed raw MOM to preterm infants due to transportation and storage of small volumes that might be pumped away from the infant, and a concern that they might harbor bacteria. However, the higher availability of bioactive components in raw MOM may provide benefits to preterm infants compared to frozen or pasteurized MOM.

RESEARCH AIM

To systematically review and summarize the results of studies on feeding raw MOM versus frozen or pasteurized MOM to preterm infants born at less than 37 weeks of gestation.

METHODS

Four databases were searched (Cochrane, Embase, Ovid MEDLINE, and Web of Science) for this systematic review. Of 542 studies identified, nine met inclusion criteria and were critically evaluated using the quality assessment tool for quantitative studies by the Effective Public Health Practice Project. Studies were organized using the Breastfeeding Challenges Facing Preterm Mother-Infant Dyads theoretical framework.

RESULTS

Included studies evaluated the outcomes of preterm infants fed raw versus pasteurized MOM (n = 7, 77.8%) or raw versus frozen MOM (n = 2, 22.2%). Researchers found that raw MOM did not increase infant infections and may have improved health and growth outcomes for study participants.

CONCLUSION

There is laboratory evidence supporting the safety and efficacy of the use of raw MOM for preterm infants. A raw MOM diet is recommended for preterm infants by professional organizations. Despite this, it may not be universally prioritized and could require purposeful implementation by each institution. Further research is needed to pursue the potential benefits of a raw MOM diet for preterm infants.

Utilization and Reporting of Patient-Reported Outcome Measures in Randomized Clinical Trials of Acute Stroke (2010-2020)

BACKGROUND

Patient-reported outcome measures (PROMs) describe health status from the perspective of the patient. There is growing interest in incorporating PROMs into clinical trials, but the extent that such measures are used in contemporary stroke trials is uncertain. We sought to determine how often acute stroke trials included PROMs as outcome measures and assessed the completeness of methodological reporting.

METHODS

We searched MEDLINE for randomized controlled trials published in 9 high-impact journals between 2010 and 2020. Eligible studies were phase 2 or 3 trials that tested therapeutic interventions within 1 month of stroke onset. Using the trial's primary publication and protocol, we abstracted key study characteristics including all primary and secondary outcome measures. We defined PROMs as self-reported measures of quality of life, symptoms, or function collected without interpretation of an external party.

RESULTS

Of 116 trials that met eligibility, 57 (49%) included at least 1 PROM. Of these, 41 trials (35%) included a PROM in its primary publication, while 16 (14%) identified a PROM in its protocol. Only 1 trial used a PROM as a primary outcome. Among the 57 total trials, the most commonly used measures were Euro-QOL (n=41, 72%), Stroke Impact Scale (n=10, 18%), and Short-Form 36 (n=6, 11%). Trials were more likely to include a PROM if they were published after 2016, were phase 3, or included only hemorrhagic stroke. Of the 41 trials that included a PROM in the primary publication, 40 (97%) provided PROM results, but only 9 (22%) found statistically significant differences between treatment groups. Quality of methodological reporting was generally poor.

CONCLUSIONS

Half of contemporary acute stroke trials published in high-impact journals listed at least 1 PROM as a secondary outcome, but they played a minor role in the presentation of the final trial results. Inclusion of PROMs in acute stroke trials requires greater attention during both the design and reporting phases of the trial.

Connor-Davidson Resilience Scale: a systematic review psychometrics properties using the COSMIN

Background

Psychometrical evaluation of persons of diverse contexts and different populations, including general or clinical.

Objective

This review study aimed to evaluate the psychometrics quality of resilience scales.

Methods

International and Iranian databases were searched with MESH terms, including "psychometric", "validity", "reliability", "Connor-Davidson resilience scale", "Resilience scale", for published articles up to 1 February 2023. For each of the selected studies, the risk of bias was evaluated using the COSMIN Risk of Bias Checklist. Then the COSMIN checklist was used to evaluate the entire text of the article for methodological quality.

Results

Considering the inclusion criteria, 80 documents were evaluated. According to the COSMIN's criteria for evaluating the risk of bias, the current study findings revealed the included studies' limitations in assessing the three versions of CD-RISC cross-cultural and content validity as well as their stability (e.g. conducting test re-test), whereas the majority of psychometric studies of CD-RISC-25, and CD-RISC-2 rated as very good or adequate in terms of structural validity. In terms of quality assessment of the included studies, the current study indicated that investigating the structural validity of the CD-RISC was mainly done based on exploratory factor analysis (EFA), and confirmatory factor analysis was absent.

Conclusion

The general result indicates the acceptability of the quality of the studies. However, concerns for measurement properties such as responsiveness and criterion validity as well as the standard error of measurement have been neglected.

Experience of stigma among persons with type 2 diabetes in Africa: a systematic review

Diabetes stigma is a pervasive social phenomenon with significant impacts on individuals living with type 2 diabetes mellitus (T2DM). Despite the negative health impact of diabetes stigma, little is known about the experience of this phenomenon in Africa. This review aimed to synthesize existing quantitative and qualitative studies that examine the experiences and outcomes of T2DM stigma in Africa. A mixed studies review methodology was utilized to conduct this research. Relevant articles were identified by searching the Cumulative Index to Nursing and Allied Health Literature, PubMed, MEDLINE and PsycINFO databases. The mixed method appraisal tool was used to assess the quality of included studies. Of 2626 records identified, 10 articles met the inclusion criteria. The prevalence of diabetes stigma was as high as 70%. The results of the review indicate that individuals with T2DM in Africa are labelled as 'having HIV', 'nearing their death' and 'wasting resources'. These experiences were associated with low quality of life, disease concealment and avoidance of self-management behaviours. The findings highlight the urgent need for further stigma-centric studies to fully understand how T2DM stigma is experienced in Africa. The evidence from such studies would inform the development and evaluation of effective interventions to address this social consequence of T2DM.

A systematic review of procedural modalities in the treatment of notalgia paresthetica

BACKGROUND

Notalgia paresthetica (NP) is a rare condition characterized by localized pain and pruritus of the upper back, associated with a distinct area of hyperpigmentation. Given the lack of standardized treatment and the uncertain efficacy of available options, applying procedural methods is of growing interest in treating NP.

AIMS

We sought to comprehensively evaluate the role of procedural treatments for NP.

METHODS

We systematically searched PubMed/Medline, Ovid Embase, and Web of Science until November 14th, 2023. We also performed a citation search to detect all relevant studies. Original clinical studies published in the English language were included.

RESULTS

Out of 243 articles, sixteen studies have reported various procedural modalities, with or without pharmacological components, in treating NP. Pharmacological procedures, including injections of botulinum toxin, lidocaine, and corticosteroids, led to a level of improvement in case reports and case series. However, botulinum toxin did not show acceptable results in a clinical trial. Moreover, non-pharmacological procedures were as follows: physical therapy, exercise therapy, kinesiotherapy, acupuncture and dry needling, electrical muscle stimulation, surgical decompression, and phototherapy. These treatments result in significant symptom control in refractory cases. Physical therapy can be considered a first-line choice or an alternative in refractory cases.

CONCLUSION

Procedural modalities are critical in the multidisciplinary approach to NP, especially for patients who are refractory to topical and oral treatments. Procedural modalities include a spectrum of options that can be applied based on the disease's symptoms and severity.

Association between visual impairment and suicide: A systematic review and meta-analysis

Visual impairment severely impacts the life of the patients. In this study, we systematically reviewed studies on the potential relationship between visual impairment and suicidal behaviour, and conducted meta-analyses on the risk estimates. We searched 11 literature databases on 20 October 2022 and identified a total of 10 eligible studies with 5.8 million participants. Suicide behaviour was investigated according to three domains: suicide ideation, suicide attempt and suicide death. In the 10 eligible studies, seven reported data on suicide ideation, five reported data on suicide attempt, and three reported data on suicide death. All summary estimates extracted for use in the meta-analyses were adjusted estimates of association since we acknowledged that depression as well as other confounding factors may play an important role. We found that visual impairment was a significant risk factor of suicide ideation (OR 1.83; 95% CI: 1.40-2.40; p = 0.000012), suicide attempt (OR 2.62; 95% CI: 1.29-5.31; p = 0.0077) and suicide death (OR 7.00; 95% CI: 2.30-21.4; p = 0.000063). These high increases in risk of suicide from visual impairment underscore the importance of eye health on the overall mental health, and the potential devastating consequences of insufficient access to eye care, lack of treatment possibilities for any reason or low political priority of eye care.

Utilising interactive technology for stroke patient education: a systematic review

PURPOSE

As a leading cause of death and disability worldwide, how to effectively manage and prevent stroke is a key consideration for health care systems. Throughout the world stroke management recommendations include education; however, not all patients receive this intervention. Advances in technology have provided health professionals with a range of innovative, effective, and modern tools that may be useful in delivering stroke education. This study aimed to systematically review the current evidence for the use of interactive technology in stroke patient education, and whether this was effective for increasing patients' stroke knowledge and behaviours that lower stroke risk.

METHODS AND MATERIALS

The protocol was registered with PROSPERO (#225223) and a literature search undertaken in Embase (including MEDLINE and PubMed), PsycInfo and CINAHL from inception until August 2022. The Mixed Methods Appraisal Tool was used to assess the methodological quality of the included articles.

RESULTS

From an initial yield of 760 articles, 10 articles met the study inclusion criteria. The articles explored a range of interactive technologies, with none of them includes articles using the same technology. All of the articles reported at least one positive effect from the technology. Two articles reported on stroke incidence post-intervention. The methodological quality of the articles varied, but was largely medium to high.

CONCLUSION

The paucity of evidence highlights a need for future studies to provide insights into the benefits of quality interactive technology-based stroke education and to identify options for optimal delivery modes in stroke education.

Me, myself, and I: A systematic review of cystic fibrosis and self-concept

Given extensive pertinent disease factors and evolving medical treatments, this systematic review explores qualitative and quantitative cystic fibrosis (CF) research surrounding self-concept, an overarching perception of self. Research methodologies, self-concept dimensions, prominent self-concept findings and clinical recommendations are identified. Preferred Reporting Items for Systematic Review and Meta-analyses guidelines were applied. PubMed, Scopus, Medline, Psycinfo, CINAHL (ebsco), and CENTRAL Cochrane electronic databases were searched from 2012 to 2022. Methodological quality was assessed using the critical appraisal skills program. Data-based convergent synthesis was applied to analyze and report on qualitative and quantitative studies in parallel. Thirty-seven publications met the inclusion criteria, most of which employed a cross-sectional, single-center design within an adolescent and adult population. Self-efficacy, self-esteem, and self-identity studies were dimensions of self-concept identified, with studies relating to self-efficacy surrounding physical health management most prevalent. All three dimensions were positively associated with improved treatment adherence and psychosocial health. Efficacy tested intervention programs to enhance self-concept are limited; however, an extensive range of clinical recommendations are offered, highlighting the importance of clinician self-concept awareness, quality clinician-patient conversations and online CF peer-support. Self-concept is an important mechanism to optimize patient outcomes. Further CF self-concept research is required, particularly multicenter, longitudinal, and interventional studies. Early childhood, post lung transplant and the older adult CF population in particular, lack research attention. Given the potential impact of rapidly evolving CF transmembrane conductance regulator modulator drugs on many aspects of self, future self-concept research beyond the dimension of self-efficacy may be beneficial.

Prognostic value of cardiac deceleration capacity in patients with atrial fibrillation after catheter ablation: A systematic review and meta-analysis

INTRODUCTION

Cather ablation (CA) is a well-recognized treatment alternative for atrial fibrillation (AF) patients despite more than 20% ablation-treated patients suffering from AF recurrence. The underlying mechanism of AF recurrence postablation is probably associated with high cardiac parasympathetic activity, which can be assessed with deceleration capacity (DC) of heart rate. Given that the relationship between DC and AF recurrence is still controversial, this systematic review and meta-analysis was performed to investigate the characteristics of DC in patients with and without AF recurrence, evaluating the prognostic value of DC in AF patients after CA.

METHODS

A literature search was systematically performed in the Embase, PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang databases until October 01, 2023. The observational studies reporting either the pre- and postablation DC in both recurrence and non-recurrence groups or the ratios based on DC for predicting AF recurrence were mainly included. Weighted mean differences (WMD) or odds ratios (OR) based on DC would be calculated with a random-effect model, if heterogeneity estimated with the I2 index and Q statistic was significant (I2 > 50% or p < .05); otherwise, a fixed-effect model would be utilized.

RESULTS

A total of eight observational studies involving 914 AF patients treated with radiofrequency or cryoballoon ablation were included in this study. Ablation-treated patients with AF recurrence had the higher DC postablation in relation to those without recurrence (WMD, 1.00; 95% confidence interval [CI], 0.33-1.67; p < .01), which was present up to 3 months of follow-up (WMD, 1.54; 95% CI, 1.11-1.96; p < .01), whereas there was no statistical significance in DC before ablation between recurrence and non-recurrence groups (WMD, 0.34; 95% CI, -0.12 to 0.79; p = .15). The high DC postablation was a risk factor for AF recurrence in ablation-treated patients (OR, 2.17; 95% CI, 1.44-3.25; p < .01).

CONCLUSION

The high DC postablation was associated with the risk of AF recurrence, suggesting that DC may act as a prognostic indicator in AF patients treated with CA.

Addressing misinformation about the Dietary Guidelines for Americans

The Dietary Guidelines for Americans (DGA) provides science-based advice on dietary intake to promote health, reduce risk of chronic disease, and meet nutrient needs. It is jointly published by the United States Departments of Health and Human Services and Agriculture (USDA) every 5 y. As chronic diseases continue to rise to pervasive levels, helping the United States population follow the DGA is especially important for improving the health of our nation. The DGA is developed using a rigorous and transparent scientific process, and with the advice of an independent, external committee of leading scientists. Career federal nutrition scientists who manage the process ensure that the methods used to develop the DGA remain state of the art. Unfortunately, misinformation about the scientific basis, transparency, and relevance of the DGA for the United States population threatens its credibility. The main objective of this article is to correct this misinformation with factual information about the process used to develop the DGA. The DGA provides guidelines for the general public, and its primary audience includes policymakers and nutrition and health professionals who help individuals and families consume a healthy dietary pattern. Providing accurate information may bolster trust in the recommendations among these audiences while improving implementation across sectors to promote better adherence to the DGA, thereby improving diet quality among the United States population.

Fracture of femoral neck in modular total hip arthroplasty: a systematic review of the literature

BACKGROUND

Modular femoral stems have the advantage of anatomic hip reconstruction by restoring the femoral offset thus minimising the bearing surface wear, implant loosening and dislocation.

AIM

This study aims to investigate the existing literature on modular neck fractures, to identify predisposing factors and guide the decision-making process in the management of these difficult cases.

METHODS

A systematic literature review was conducted until July 2022. PRISMA guidelines were followed, eligibility criteria were set, and methodology assessment of included studies was conducted based on MINORS criteria, size and primary outcome. Data were extracted and analysed thoroughly.

RESULTS

5657 studies were initially screened; the full texts of 124 records were assessed and finally, 32 reports were included. There were 7 clinical studies and 25 case reports. A total of 4825 patients (5204 hips) with a mean age 62.38 years and a mean BMI 29.06 kg/m2 were analysed in the 7 clinical studies. The reported overall weighted revision rate was 0.86%, while the weighted mean modular neck fracture rate was 0.26%. The usual history was sudden experience of hip pain and instability. The average time interval to neck fracture was 4.57 (range 3-4.7) years and a long modular neck was identified in 91.17% of them. Data from case reports showed a mean age and average BMI of 55.85 and 31.63 kg/m2. 82.35% of the patients were male. Necks were fractured after an average time interval of 64.5 ± 8.8 months.

CONCLUSIONS

The incidence of modular neck fracture is significant. The profile of a male, obese patient with a long modular neck increased risk of neck fracture. Microstructural investigation of the retrieved implants demonstrated a higher incidence of fracture line in the base of the neck junction and at its anterolateral distal part. Surgeons should be aware of this complication while using or revising such protheses.

Effect of proanthocyanidins on blood lipids: A systematic review and meta-analysis

Proanthocyanidins (PCs) are natural antioxidant polyphenols and their effect on the regulation of blood lipids is still controversial. This study was conducted to evaluate the effect of PCs on lipid metabolism. We searched PubMed, Embase, Web of Science, Chinese biomedical literature service system, China National Knowledge Internet, and Wanfang Data with no time restriction until March 18, 2022, using various forms of "proanthocyanidins" and "blood lipid" search terms. Randomized controlled trials investigating the relationship between PCs and lipid metabolism were included. The standard system of Cochrane Collaboration was used to assess the quality of studies. We standardized mean differences (SMDs) with 95% confidence interval (CI) using the random-effects model, Cohen approach. Seventeen studies (17 trials, N = 1138) fulfilled the eligibility criteria. PCs significantly reduced triglyceride, and increased recombinant apolipoprotein A1. Subgroup analysis showed a significant reduction in triglycerides in older adults (≥60 years) and total cholesterol for participants who were not overweight or obese (body mass index <24). An intervention duration of greater than 8 weeks reduced triglyceride and low-density lipoprotein cholesterol levels but increased high-density lipoprotein cholesterol. Different doses of PCs could regulate triglycerides, high-density lipoprotein cholesterol and total cholesterol. PCs have beneficial effects on circulating lipids and may represent a new approach for treating or preventing lipid metabolism disorders. However, more high-quality studies are needed to confirm these results.

Global and regional seroprevalence of coxiellosis in small ruminants: A systematic review and meta-analysis

BACKGROUND

Coxiellosis is a neglected zoonosis for occupationally exposed people in many parts of the world. Sheep and goats are two important small ruminants that act as reservoirs for human contamination; however, there is a lack of comprehensive data on the epidemiological aspects of coxiellosis in sheep and goats at regional and global levels. The aim of this study was to systematically review the available articles on seroprevalence of coxiellosis in sheep and goats and estimate the overall seroprevalence in different regions.

METHODS

A systematic search strategy was performed in five electronic repositories for articles published until December 2021. Relevant data were extracted from the selected articles based on the inclusion criteria. A random effect meta-analysis model was used to analyse the data. Results are presented as the prevalence of seropositivity as a percentage and 95% confidence intervals.

RESULTS

The global pooled seroprevalence of coxiellosis in sheep was 17.38% (95% confidence interval [CI]: 15.59%-19.17%). Overall, the regional level pooled prevalence estimates in sheep ranged from 15.04% (95% CI: 7.68%-22.40%) to 19.14% (95% CI: 15.51%-22.77%), depending on region. The global pooled seroprevalence of coxiellosis in goats was 22.60% (95% CI: 19.54%-25.66%). Overall, the regional level pooled prevalence estimates in goats ranged from 6.33% (95% CI: 2.96%-9.71%) to 55.13% (95% CI: 49.61%-60.65%), depending on the region. The prevalence estimates also varied significantly in both sheep and goats depending on age, sex, and rearing systems of the animals (p < 0.001).

CONCLUSION

Seroprevalence of coxiellosis in both sheep and goats is considerable. Routine monitoring of the sheep and goat populations is needed to prevent spillover infection in other livestock and humans.

Comparative efficacy of telehealth interventions on promoting cancer screening: A network meta-analysis of randomized controlled trials

BACKGROUND

Cancer screening is a pivotal method for reducing mortality from disease, but the screening coverage is still lower than expected. Telehealth interventions demonstrated significant benefits in cancer care, yet there is currently no consensus on their impact on facilitating cancer screening or on the most effective remote technology.

DESIGN

A network meta-analysis was conducted to detect the impact of telehealth interventions on cancer screening and to identify the most effective teletechnologies.

METHODS

Six English databases were searched from inception until July 2023 to yield relevant randomized controlled trials (RCTs). Two individual authors completed the literature selection, data extraction, and methodological evaluations using the Cochrane Risk of Bias tool. Traditional pairwise analysis and network meta-analysis were performed to identify the overall effects and compare different teletechnologies.

RESULTS

Thirty-four eligible RCTs involving 131,644 participants were enrolled. Overall, telehealth interventions showed statistically significant effects on the improvement of cancer screening. Subgroup analyses revealed that telehealth interventions were most effective for breast and cervical cancer screening, and rural populations also experienced benefits, but there was no improvement in screening for older adults. The network meta-analysis indicated that mobile applications, video plus telephone, and text message plus telephone were associated with more obvious improvements in screening than other teletechnologies.

CONCLUSION

Our study identified that telehealth interventions were effective for the completion of cancer screening and clarified the exact impact of telehealth on different cancer types, ages, and rural populations. Mobile applications, video plus telephone, and text message plus telephone are the three forms of teletechnologies most likely to improve cancer screening. More well-designed RCTs involving direct comparisons of different teletechnologies are needed in the future.

CLINICAL RELEVANCE

Telehealth interventions should be encouraged to facilitate cancer screening, and the selection of the optimal teletechnology based on the characteristics of the population is also necessary.

Targeted Muscle Reinnervation and Regenerative Peripheral Nerve Interfaces Versus Standard Management in the Treatment of Limb Amputation: A Systematic Review and Meta-Analysis

Introduction: Painful neuromas are a common postoperative complication of limb amputation often treated with secondary reinnervation. Surgical reinnervation include Targeted Muscle Reinnervation (TMR) and Regenerative Peripheral Nerve Interface (RPNI), and can be primary and secondary. The aim of this review is to assess the effects of primary TMR/RPNI at the time of limb amputation on the incidence and intensity of post-operative neuroma and pain. Methods: This review was registered a priori on PROSPERO (CRD42021264360). A search of the following databases was performed in June 2021: Medline, EMBASE, and CENTRAL. Unpublished trials were searched using clinicaltrials.gov. All randomized and non-randomized studies assessing amputation with a reinnervation strategy (TMR, RPNI) were included. Outcomes evaluated included the incidences of painful neuroma, phantom limb pain (PLP), residual limb pain (RLP), as well as severity of pain, and Pain intensity, behavior, and interference (PROMIS). Results: Eleven studies were included in this systematic review, and five observational studies for quantitative synthesis. Observational study evidence suggests that TMR/RPNI results in a statistically significant reduction in incidence, pain scores and PROMIS scores of PLP and RLP. Decreased incidence of neuromas favored primary TMR/RPNI, but this did not achieve statistical significance (p = 0.07). Included studies had moderate to critical risk of bias. Conclusion: The observational data suggests that primary TMR/RPNI reduces incidence, pain scores and PROMIS scores of PLP and RLP. Going forward, randomized trials are warranted to evaluate this research question, particularly to improve the certainty of evidence.

Multimodal exercise programs may improve posttraumatic stress disorders symptoms and quality of life in adults with PTSD: An overview of systematic reviews with meta-analysis

OBJECTIVE

This overview of reviews aimed to summarize the effectiveness of exercise, regular physical activity or mind-body exercises on posttraumatic stress disorder (PTSD) symptoms and comorbidities associated with PTSD (e.g. depression symptoms) among individuals without age, gender, race, ethnicity or setting restrictions.

DATA SOURCES

The CINAHL, Embase, PubMed and SPORTDiscus databases were searched from inception to November 16, 2023.

REVIEW METHODS

Systematic reviews with meta-analysis of randomized clinical trials evaluating exercise, regular physical activity or mind-body exercises were considered. Control groups and outcome measures were not restricted. AMSTAR 2 assessed the methodological quality of reviews. The overlap between reviews was calculated.

RESULTS

A total of 14 systematic reviews were included meta-analyzing 23 distinct randomized clinical trials. There was a very high overlap between reviews (corrected covered area = 16%). PTSD symptoms, depression symptoms, anxiety symptoms, sleep quality, substance abuse and quality of life were meta-analyzed. No reviews meta-analyzed the effects of regular physical activity. Overall, the meta-analyses found multicomponent exercise programs may have positive results in reducing PTSD symptoms and improving quality of life. In addition, the results of yoga were inconsistent across the meta-analyses for PTSD symptoms, and no differences between groups were found in favor of yoga for depression symptoms. Finally, no specific conclusions could be made about anxiety symptoms, sleep quality and substance abuse.

CONCLUSION

A multicomponent exercise program may be effective in improving PTSD symptoms and quality of life, whereas yoga may be ineffective for depression symptoms in adults with PTSD.

Vasovasostomy: A systematic review and meta-analysis comparing macroscopic, microsurgical, and robot-assisted microsurgical techniques

BACKGROUND AND OBJECTIVES

Vasovasostomy is a cost-effective procedure for the reversal of vasectomy. A water-tight adequately blood-supplied mucosal anastomosis is required for better outcomes. This review aimed to compare the outcome of vasovasostomy performed by three different techniques: macroscopic, pure microsurgical, and robot-assisted microsurgical techniques.

METHODS

Scopus, Web of Science, PubMed, Embase, and Cochrane library databases were searched for relevant studies from January 1901 to June 2023. We conducted our quantitative syntheses using the inverse variance method in OpenMeta software. The study's protocol was registered on PROSPERO.

RESULTS

This review involved 95 studies of different designs, with a total sample size of 48,132. The majority of operations were performed bilaterally, and participants were monitored for up to 10 years. The pooled patency rate was the highest following robot-assisted vasovasostomy (94.4%), followed by pure microsurgical vasovasostomy (87.5%), and macroscopic vasovasostomy (83.7%). The pooled pregnancy rate following purely microsurgical vasovasostomy was higher than that of macroscopic vasovasostomy (47.4 vs. 43.7%). Definitive pregnancy rates in robotic vasovasostomy are yet to be determined.

CONCLUSION

Patency outcomes for vasovasostomy were best with robot-assisted microsurgical technique, followed by pure microsurgical technique, and conventional macroscopic technique. Further investigations of robot-assisted microsurgical vasovasostomy outcomes and randomized control trials are required to support this evidence.

Intravenous fluid rate of 250 mL/h versus 125 mL/h in nulliparous women: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Evidence regarding the type and rate of intravenous (IV) fluid administration during labor is still inconclusive and the studies assessing the impact of IV fluids had mixed results.

OBJECTIVES

To evaluate the effects of IV fluids at an infusion rate of 250 mL/h as compared with 125 mL/h on labor outcomes in nulliparous women.

SEARCH STRATEGY

We searched six databases for relevant studies through a search strategy containing the relevant keywords "IV hydration", "IV fluids", and "labor" from the inception of these databases to May 1, 2023, without any applied restrictions.

SELECTION CRITERIA

Search results were imported to Covidence for screening of eligible articles for this review. Randomized controlled trials (RCTs) assessing the impact of IV fluids at 250 mL/h on the outcomes of labor in nulliparous women at term (>37 weeks) as compared with 125 mL/h were included only.

DATA COLLECTION AND ANALYSIS

Data regarding the characteristics of included studies, participant's baseline characteristics, and concerned outcomes were collected in an Excel spreadsheet and all the concerned outcomes were pooled as risk ratios (RR) or mean difference (MD) with 95% confidence interval (CI) in the meta-analysis models using RevMan 5.4.

MAIN RESULTS

Pooled data from 11 RCTs with 1815 patients showed that 250 mL/h infusion rate had a significant reduction in cesarean section rate (RR 0.70, 95% CI 0.56-0.88, P = 0.002), the first stage of labor duration (MD -46.97, 95% CI -81.79 to -12.14, P = 0.008), the second stage of labor duration (MD -2.69, 95% CI -4.34 to -1.05, P = 0.001), prolonged labor incidence (RR 0.72, 95% CI 0.58-0.89, P = 0.003), as compared with 125 mL/h. Also, the vaginal delivery rate (RR 1.07, 95% CI 1.02-1.12, P = 0.009) was higher with a 250 mL/h infusion rate.

CONCLUSION

IV fluids at an infusion rate of 250 mL/h during labor in nulliparous women decreased the cesarean delivery rate, increased the vaginal delivery rate, shortened the first and second-stage labor duration, decreased the incidence of prolonged labor as compared with 125 mL/h. These findings suggest enhanced labor progression and a lower risk of labor complications with higher infusion rates. However, future research involving a more diverse population and exploring the potential benefits of combining IV infusion rates with other interventions, such as adding dextrose or less restrictive oral intake during labor, is needed.

What works in peer support for breast cancer survivors: A qualitative systematic review and meta-ethnography

Breast cancer is associated with adverse physical and psychological consequences. Although research has identified the various benefits linked to psychosocial interventions, mixed results have been found in relation to peer support. The aim of the present systematic review and meta-ethnography is to explore the qualitative evidence on the experience of breast cancer survivors in peer support. A systematic search of the literature was conducted until June 2023, and a meta-ethnographic approach was used to synthesize the included papers. Eleven articles were included, collecting the experience of 345 participants. The following four core areas involved in peer support implementation were identified from the synthesis: Peer support can create understanding and a mutual therapeutic and emotional connection; peer support can facilitate an educational and supportive patient-centered journey; peer support should monitor group members for unpleasant emotional experiences; peer support should have professional supervision of recruitment and training to prioritize quality. These results can be used as patient-centered insights by healthcare professionals to provide evidence-informed peer support programs and address current limitations in the field.

Post-diagnosis physical activity and sedentary behaviour and colorectal cancer prognosis: A Global Cancer Update Programme (CUP Global) systematic literature review and meta-analysis

Low physical activity and high sedentary behaviour have been clearly linked with colorectal cancer development, yet data on their potential role in colorectal cancer survival is limited. Better characterisation of these relationships is needed for the development of post-diagnosis physical activity and sedentary behaviour guidance for colorectal cancer survivors. We searched PubMed and Embase through 28 February 2022 for studies assessing post-diagnosis physical activity, and/or sedentary behaviour in relation to all-cause and cause-specific mortality and recurrence after colorectal cancer diagnosis. Total and recreational physical activity were assessed overall and by frequency, duration, intensity, and volume using categorical, linear, and non-linear dose-response random-effects meta-analyses. The Global Cancer Update Programme (CUP Global) independent Expert Committee on Cancer Survivorship and Expert Panel interpreted and graded the likelihood of causality. We identified 16 observational studies on 82,220 non-overlapping patients from six countries. Physical activity was consistently inversely associated with colorectal cancer morbidity and mortality outcomes, with 13%-60% estimated reductions in risk. Sedentary behaviour was positively associated with all-cause mortality. The evidence had methodological limitations including potential confounding, selection bias and reverse causation, coupled with a limited number of studies for most associations. The CUP Global Expert panel concluded limited-suggestive evidence for recreational physical activity with all-cause mortality and cancer recurrence. Total physical activity and its specific domains and dimensions, and sedentary behaviour were all graded as limited-no conclusion for all outcomes. Future research should focus on randomised trials, while observational studies should obtain objective and repeated physical activity measures and better adjustment for confounders.

Risk factors for recurrence in patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative early breast cancer in Japan: a systematic literature review and meta-analysis

BACKGROUND

The clinicopathological factors indicating risk of recurrence are used to guide the choice of perioperative therapy in patients with breast cancer. Although several risk factors for recurrence have been reported in patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) early breast cancer in Japan, there has been no systematic review quantifying potential risk factors.

METHODS

We performed a systematic literature review and meta-analysis using the MEDLINE, Embase, Cochrane CENTRAL, and Japan Medical Abstract Society databases to identify risk factors for recurrence in HR+/HER2- early breast cancer in Japan. The primary outcome was relapse-free or disease-free survival (RFS/DFS), and the secondary outcomes were overall survival and breast cancer-specific survival (BCSS).

RESULTS

Searches identified 42 eligible publications. Meta-analyses identified lymph node metastasis (hazard ratio: 2.76 [95% confidence interval: 1.97-3.88]), large tumor size (1.67 [1.24-2.23]), high histological grade (1.50 [1.04-2.16]), and high nuclear grade (2.02 [1.61-2.54]) as risk factors for RFS/DFS. Lymph node metastasis (2.43 [1.28-4.63]), large tumor size (1.80 [1.24-2.62]), and high histological grade (2.02 [1.44-2.84]) were also risk factors for overall survival, and high progesterone status was a possible favorable prognostic factor for BCSS (0.20 [0.10-0.42]).

CONCLUSIONS

Identified risk factors were consistent with the previous reports, and this study provides quantitative summary of risk factors for HR+/HER2- early breast cancer recurrence in Japan. (PROSPERO Registration ID, CRD42022338391.).

Association between Diabetes and Exfoliation Syndrome

Topic

This systematic review and meta-analysis summarizes the existing evidence for the association of diabetes mellitus (DM) and exfoliation syndrome (XFS).

Clinical Relevance

Understanding and quantifying these associations may aid clinical guidelines or treatment strategies and shed light on disease pathogenesis. The role of DM in determining XFS risk may also be of interest from an individual or public health perspective.

Methods

The study protocol was preregistered on the International Prospective Register of Systematic Reviews with registration number CRD42023429771. We systematically searched PubMed and Embase from inception to June 15, 2023. Screening and full-text review were conducted by 2 independent reviewers. All observational studies reporting an age-adjusted odds ratio (OR) and 95% confidence interval (CI) for the association between DM and XFS among adults were included. Quantitative synthesis involved a random-effects meta-analysis using the DerSimonian-Laird method to generate a pooled OR. Risk of bias was evaluated using the Newcastle-Ottawa Scale.

Results

Fourteen studies (9 cross-sectional and 5 case-control) comprising 47 853 participants were included in the systematic review and meta-analysis. Random-effects meta-analysis indicated no overall association between DM and XFS (OR 0.94; 95% CI, 0.73–1.21; I 2  = 68.5%). However, subgroup analysis revealed a significant inverse association among individuals ≥ 65 years (OR 0.71; 95% CI, 0.54–0.93) versus individuals < 65 years (OR 1.22; 95% CI, 0.80–1.87; P effect modification  = 0.04). The relation between DM and XFS was also inverse in case-control studies (OR 0.75; 95% CI, 0.58–0.97) but was nonsignificant in cross-sectional studies (OR 1.17; 95% CI, 0.83–1.66; P effect modification  = 0.04). Overall risk of bias was low, with tests for publication bias showing P  ≥ 0.06.

Conclusion

This meta-analysis suggests no association between DM and XFS overall, with possible inverse associations of DM with XFS in older populations. However, given the substantial heterogeneity and borderline significance for publication bias, these findings should be interpreted with caution. Our results give insight into the unique etiology and clinical relevance of XFS while proposing the need for larger longitudinal and genetic biomarker studies.

Clinical role of the long non‑coding RNA, EGFR‑AS1, in patients with cancer: A systematic review and meta‑analysis

The novel long non-coding RNA, EGFR-AS1, is expressed in various types of solid tumour, and its oncogenic role has been fully identified. In the present study, several articles were screened following an electronic search of the PubMed database. In total, 8 studies were included in the present systematic review. For each analysis indicator risk ratios (RRs) with 95% confidence intervals (CIs) or hazard ratios (HRs) with standard errors and 95% CIs were estimated using Review Manager 5.3. The pooled RR of high EGFR-AS1 expression among patients with or without vascular invasion was 1.81 with a 95% CI of 1.22-2.69; the pooled HR of high EGFR-AS1 expression for patient overall survival rate was 1.74 with a 95% CI of 1.39-2.18. Therefore, EGFR-AS1 was identified as an oncogene and the upregulated EGFR-AS1 expression was significantly associated with advanced tumour progression and poor prognosis.

Topical non-steroidal anti-inflammatory drugs for central serous chorioretinopathy: A systematic review and meta-analysis

Central serous chorioretinopathy (CSC) is a prevalent exudative maculopathy and the ongoing verteporfin shortage restricts current treatment possibilities. Topical non-steroidal anti-inflammatory drugs (NSAID) have previously been proposed as a treatment for CSC, although its exact efficacy remains unclear. In this systematic review and meta-analysis, we outlined the efficacy of topical NSAIDs for the treatment of CSC. We searched 11 literature databases on 13 December 2022, for any study describing topical NSAID treatment for CSC. Thirteen eligible studies were included with a total of 1001 eyes of 994 patients with CSC. Six studies were case reports, two were cohort studies and five were non-randomized comparative studies. Where specified, topical NSAIDs used were bromfenac 0.09%, diclofenac 0.1%, ketorolac 0.4% and 0.5%, pranoprofen 0.1%, and nepafenac 0.1% and 0.3%. Studies were predominantly of cases with acute CSC and several case studies reported treatment outcomes simultaneously with discontinuation of corticosteroid use, which complicated treatment evaluation. Meta-analyses of comparative studies revealed a statistically significant but clinically irrelevant best-corrected visual acuity improvement of -0.04 logMAR (95% CI: -0.07 to -0.01 logMAR; p = 0.01) at 1-month follow-up, which became statistically insignificant at 3-month follow-up (-0.03 logMAR; 95% CI: -0.06 to 0.003 logMAR; p = 0.08). Further, we found no benefit in complete subretinal fluid resolution at 1-month follow-up (OR: 1.20; 95% CI: 0.81-1.76; p = 0.37) or 3-month follow-up (OR: 1.17; 95% CI: 0.86 to 1.59; p = 0.33). Taken together, available evidence does not support the use of topical NSAIDs for the treatment of CSC.

Return to Sport After Pediatric Anterior Cruciate Ligament Reconstruction: A Systematic Review of the Criteria

BACKGROUND

Postoperative rehabilitation is an important component of recovery after anterior cruciate ligament (ACL) reconstruction (ACLR), facilitating successful return to sport (RTS) by reducing risk factors for repeat injury.

PURPOSE

This systematic review aimed to determine the best protocol for RTS after ACLR in children.

STUDY DESIGN

Systematic review; Level of evidence, 4.

METHODS

PubMed, Embase, PEDro, SPORTDiscus, and Web of Science databases were searched from October 3, 2014, to November 3, 2022. The inclusion criteria were the pediatric population (<18 years old) after ACLR with clear RTS criteria and/or mean/median time to RTS. Multiligament knee injuries were excluded from this study. The methodologic quality of the included articles was assessed using the methodological index for non-randomized studies (MINORS). The highest possible score was 24 points for comparative studies (ie, a study comparing 2 protocols or more). Noncomparative studies or studies with a single protocol could score a maximum of 16 points as assessed by the MINORS score.

RESULTS

The search yielded 1816 titles, and 24 were retained based on the inclusion and exclusion criteria. Every study was published between 2015 and 2022. Among the 24 studies included, 13 were retrospective and 11 were prospective. The mean MINORS score for the noncomparative studies was 13 of 16 (n = 23) and 23 of 24 for the comparative study (n = 1). The studies were categorized into unspecified clearance (n = 10), milestone based (n = 13), and combined time and milestone (n = 1). A total of 1978 patients (57% female) were included in the review. The mean age at ACLR was 14.7 years. The most common endpoint used was graft rupture (0% to 35%). In the unspecified group, the quickest RTS was 5.8 months and the longest was 9.6 months. Statistically significant risk factors for ACL reinjury included younger age and earlier RTS. The latter was a significant contributor to graft failure for combined time-based and milestone-based RTS. In the milestone-based group, the most common criteria were ≥90% limb symmetry measured using hamstring strength, quadriceps strength, and/or hop tests. The mean RTS time was 6.8 to 13.5 months.

CONCLUSION

RTS should be delayed, when possible, especially in the younger population. A combination of quantitative tests and qualitative tests is also recommended. However, optimal RTS criteria have yet to be determined. Future prospective studies should focus on comparing the different times and milestones currently available.

Outcomes After Revision Arthroscopic Rotator Cuff Repair: A Systematic Review

BACKGROUND

Arthroscopic rotator cuff repair (ARCR) is one of the most commonly performed orthopaedic procedures; however, it is unclear how to manage patients with symptomatic retears.

PURPOSE

To perform a systematic review to evaluate the outcomes of revision ARCR in the literature.

STUDY DESIGN

Systematic review; Level of evidence, 4.

METHODS

A systematic literature search based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed utilizing the Embase, MEDLINE, and Cochrane Library databases. Eligible for inclusion were clinical studies reporting on revision rotator cuff repair. Clinical outcomes were recorded.

RESULTS

The 17 included studies were composed of 888 shoulders in 885 patients. The mean age of the 885 patients was 58.6 ± 9.1 years, with a mean follow-up of 28.1 ± 22.1 months. The mean visual analog scale score was 2.1 ± 1.8, the mean American Shoulder and Elbow Surgeons score was 75.0 ± 18.3, and the mean Constant score was 67.4 ± 16.6. The overall rate of retears after revision was 25.3%, with an 8.0% reoperation rate including 2.7% undergoing reverse shoulder arthroplasty and 2.0% undergoing subsequent rotator cuff repair. Finally, the complication rate was 8.6%.

CONCLUSION

Revision ARCR improved patient-reported outcomes, with 92% of patients free from reoperations at a mean follow-up of 2 years. Overall, 78.4% of patients were satisfied at final follow-up; however, the rate of retears was found to be higher than after primary ARCR.

Guideline Recommendations on Behavioral and Psychological Symptoms of Dementia: A Systematic Review

OBJECTIVE

To synthesize recommendations on assessing and managing behavioral and psychological symptoms of dementia (BPSDs) in existing clinical practice guidelines on dementia care to learn from and adapt recommendations to a Canadian context and language for describing BPSDs.

DESIGN

Systematic review.

SETTING AND PARTICIPANTS

Moderate to high-quality clinical practice guidelines on dementia care that made 1 or more recommendations on BPSD assessment or management.

METHODS

We searched MEDLINE, Embase, JBI EBM, PsycINFO, AgeLine, and gray literature for clinical practice guidelines on dementia care making recommendations on BPSD, published between January 1, 2011, and October 13, 2022. Two independent reviewers conducted study screening and data abstraction. Four independent reviewers completed quality appraisal using the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool; included guidelines had a mean overall AGREE II score ≥4.

RESULTS

Our systematic review identified 23 moderate to high-quality clinical practice guidelines (264 recommendations). The mean overall quality score on the AGREE II tool ranged from 4 to 6.5. Recommendations were clearly presented (mean clarity of presentation score 73.5%), but guideline applicability was not consistently addressed (mean applicability score 39.3%). BPSD was the most prevalent term describing neuropsychiatric symptoms (number of guidelines [n] = 14). People with lived experience contributed to 6 guidelines (26.1%). Ten guidelines (43.5%) described 1 or more health equity considerations. Guidelines made recommendations for assessing and managing agitation (n = 12), aggression (n = 10), psychosis (n = 11), depression (n = 9), anxiety (n = 5), apathy (n = 6), inappropriate sexual behavior (n = 3), nighttime behavior (n = 5), and eating disturbances (n = 3). There was substantial variability in recommendation statements, evidence quality assigned to each statement, and strength of recommendations.

CONCLUSIONS AND IMPLICATIONS

There are several moderate to high-quality clinical practice guidelines making recommendations on BPSD assessment and management, but variability in recommendation statements across guidelines and insufficient consideration of guideline applicability may hamper guideline dissemination and implementation in clinical practice.

A systematic review and meta-analysis of extra-intestinal manifestation of inflammatory bowel disease in the Eastern Mediterranean Region (EMRO) countries

Background

Inflammatory bowel disease which is subgrouped mainly to ulcerative colitis and Crohn's disease is thought to be a multi-organ disease. Most organs can be involved in the disease course in addition to gastrointestinal tract involvement. In this systematic review we aimed to assess the prevalence of these manifestations in Eastern Mediterranean Regional Office (EMRO) countries.

Method

The present systematic review and meta-analysis study was performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guideline. Joanna Briggs Institute (JBI) Critical Appraisal Checklist was admired for the quality evaluation of the included studies. For determining the heterogeneity, we used Cochran test and I2 statistics.

Result

Finally, 12 studies were included in our study. Based on the results of our study the prevalence of arthritis in ulcerative colitis and Crohn's disease patients was 7.1% (95% CI: 2.6-18.2%) and 13.5% (95% CI: 2.6-47.3%), respectively. Prevalence of arthralgia in ulcerative colitis patients was 18.4% (95% CI: 14.3-23.3%). skin involvement prevalence was 9.9% (95% CI 4.7-19.6%) in inflammatory bowel disease (IBD) patients. ocular involvement prevalence was 7.2% (95% CI 17-25.8%) in IBD patients. PSC prevalence in ulcerative colitis and Crohn's disease patients was 3.5% (95% CI: 1.7-7.3%) and 2.7% (95% CI: 1.3-5.5%), respectively.

Conclusion

Based on the results of this study arthralgia and arthritis were the most common extra-intestinal manifestation of IBD followed by dermatologic and ocular involvements. This extra-intestinal manifestation can challenge the patients' management and identifying their pattern is important during the disease course.

Prevalence and predictors of traditional medicine use among persons with diabetes in Africa: a systematic review

The utilization of traditional medicine (TM) is prevalent among the general population in Africa; however, its use among individuals with diabetes in the region remains underdocumented. This review aimed to synthesize the available literature to identify the prevalence and predictors of TM use among persons with diabetes in Africa. A systematic search was conducted across multiple databases, including MEDLINE, Embase, CINAHL, and AMED, covering studies published from 2000 to April 2023. Of 1560 records identified, 24 articles met the inclusion criteria. The prevalence of TM use varied significantly, ranging from 12.4% to 77.1%, with a median prevalence of 50%. TM was commonly used concurrently with conventional medicine (CM) (35.4-88.4%), with a majority (63.8-91.3%) not disclosing TM use to healthcare providers. Female gender, long diabetes duration, use of oral antiglycaemic medication and family history of diabetes emerged as the most common factors that predicted the use of TM. This review highlights the widespread use of TM among individuals with diabetes in Africa, often in conjunction with CM. The high prevalence of undisclosed TM use emphasizes the urgent need for healthcare providers to actively inquire about TM use during clinical consultations to address potential herb-drug interactions and adverse effects.

Tendon Transfers, Nerve Grafts, and Nerve Transfers for Isolated Radial Nerve Palsy: A Systematic Review and Analysis

BACKGROUND

Isolated radial nerve palsy is a debilitating injury that may potentially be reconstructed with either tendon transfers, nerve grafts, or nerve transfers. Currently, there is no consensus on the optimal technique for reconstruction. We performed a systematic review and analysis to determine which surgical intervention provides the best clinical outcomes.

METHODS

A systematic review was conducted according to PRISMA guidelines. Twenty-nine papers met inclusion criteria. Grading scales of function and strength were converted into a tripartite scoring system to compare outcomes between techniques. χ2 analyses were performed with a P value < .05.

RESULTS

Seven hundred fifty-four patients were analyzed. Tendon transfers resulted in the highest percentage of good outcomes (82%) and the lowest percentage of poor outcomes (9%). Tendon transfers were superior to nerve grafts and nerve transfers for restoration of wrist extension. Nerve transfers for wrist extension were superior to nerve transfers for finger extension. Nerve grafts and nerve transfers had equivalent rates of good and poor clinical outcomes.

CONCLUSIONS

This study analyzed reported outcomes of tendon transfers, nerve grafts, and nerve transfers for reconstruction of isolated radial nerve palsy. On pooled analysis, tendon transfers had higher rates of superior clinical outcomes as compared with nerve transfers and nerve grafts. Tendon transfers should be considered first-line reconstruction for isolated radial nerve palsy as nerve-based reconstruction is less predictable and reproducible.

Structural barriers to help-seeking in first-episode psychosis: A systematic review and thematic synthesis

AIM

Access to timely treatment is key to early intervention in psychosis. Despite this, barriers to treatment exist. In this review, we aimed to understand the structural barriers that patients and caregivers face in help-seeking for first-episode psychosis, and the recommendations provided to address these.

METHODS

We conducted a systematic review (PROSPERO: CRD42021274609) of qualitative studies reporting structural barriers to help-seeking from the patient or caregiver perspective. Searches were performed in September 2023, restricted to studies published from 2001. Study quality was appraised using Critical Appraisal Skills Programme. Data were analysed using thematic synthesis.

RESULTS

Nineteen papers from 11 countries were included. Across all papers, participants reported experiencing structural barriers to receiving healthcare. For many patients and caregivers, the process of accessing healthcare is complex. Access requires knowledge and resources from parents, caregivers and healthcare providers, yet too often there is a misalignment between patients' needs and service resources. Expertise amongst healthcare providers vary and some patients and caregivers experience negative encounters in healthcare. Patients highlighted earlier caregiver involvement and greater peer support as potential routes for improvement.

CONCLUSION

Patients and caregivers face multiple structural barriers, with legislative practices that discourage family involvement, and healthcare and transport costs found to be particularly problematic. Understanding these barriers can facilitate the co-design of both new and existing services to provide easier access for patients and caregivers. Further research is needed focusing not only on the perspectives of patients and caregivers who have accessed professional help but also crucially on those who have not.

Attitudes and perceptions of cancer patients and healthcare providers towards prehabilitation: A thematic synthesis

PURPOSE

Prehabilitation, which is the process of enhancing functional capacity before undergoing surgery or other treatments, has been shown to improve cancer patients' outcomes. Patient and healthcare provider attitudes and perceptions are essential factors in the successful implementation of prehabilitation. The purpose of this systematic review is to synthesize qualitative evidence and explore the barriers and facilitators to prehabilitation implementation.

METHODS

From the earliest available date to October 2023, 7 databases (PubMed, Web of Science, Cochrane Library, Embase, CINAHL, PsycINFO, and MEDLINE) were searched for a systematic review. Data were extracted, thematically analysed, and mapped onto the Capability, Opportunity, and Motivation Model of Behaviour (COM-B). The Critical Appraisal Skills Programme (CASP) tool was used to assess the quality of the studies.

RESULTS

A total of 26 studies were included, involving 377 patients, 51 caregivers, and 156 healthcare providers. 16 factors were identified and mapped onto the COM-B model: reflective/automatic motivation, physical/social opportunity, physical/ psychological capability.

CONCLUSIONS

Patients and healthcare provides identified a lack of reflective motivation and physical opportunities as the most significant barriers to engagement in prehabilitation. Personalized approaches, social support, and healthcare providers' engagement are key factors for prehabilitation. Future research should focus on developing effective interventions to enhance the uptake and sustainability of prehabilitation.

Procedures and measurement properties of the 6-min step test: A systematic review with clinical recommendations

OBJECTIVE

To provide information regarding the procedures, safety, tolerability, and measurement properties of the 6-min step test.

DATA SOURCES

MEDLINE, EMBASE, CINAHL, and SPORTDiscus (from inception until January 2024).

REVIEW METHODS

Studies that examined adults with acute or chronic diseases, and outcomes related to procedures, safety, tolerability, or measurement properties of the 6-min step test were included. Outcome data were summarized and combined in meta-analyses. The quality of included studies was assessed by the Consensus-based Standards for the selection of health Measurement Instruments checklist, and the quality of evidence was determined according to the Grading of Recommendations Assessment, Development, and Evaluation system.

RESULTS

Fourteen studies, involving 847 participants, were included. All studies performed the 6-min step test in 6 min; however, some studies varied the step height and the use of upper limb support. The test appears to be safe and well tolerated by individuals. Moderate- to high-quality evidence demonstrated appropriate results for test-retest reliability (4 studies; Intraclass correlation coefficient 0.96; 95% CI 0.91-0.98; n = 125), criterion validity (4 studies; r = 0.53; 95% CI 0.30-0.71; n = 307), and construct validity (4 studies; r = 0.63; 95% CI 0.52-0.73; n = 233).

CONCLUSION

This review provides recommendations for applying the 6-min step test in clinical and research settings. No adverse events were reported, and the test appears to be well tolerated. Adequate results were found for test-retest reliability, criterion validity, and construct validity.

The impact of different states of type 2 diabetes when stratified by baseline HbA1c on the periodontal outcomes of non-surgical periodontal treatment: A systematic review and network meta-analysis

BACKGROUND

Type 2 diabetes mellitus (T2DM) has been considered by many studies to have a bidirectional relationship with periodontitis. This systematic review and network meta-analysis aimed to investigate the impact of different states of T2DM when stratified by baseline HbA1c on the clinical outcomes of non-surgical periodontal treatment (NSPT).

METHODS

This study followed the Preferred Reporting Items for Meta-Analyses (PRISMA) guidelines and involved an electronic literature search (from inception to the 2nd of January 2023). The study included at least two groups of patients: chronic periodontitis only (No-DM) or periodontitis and well-controlled/poorly controlled type 2 diabetes mellitus (WC/PC-T2DM). Clinical outcomes included probing depth (PD) reduction, bleeding on probing reduction, and clinical attachment level (CAL) gain. Direct and indirect comparisons between groups were assessed by network meta-analysis, thus allowing us to establish a treatment ranking.

RESULTS

Ten prospective cohort studies (11 data sets) were included for qualitative analysis and network meta-analysis. The data included in this study had high consistency; in addition, a funnel plot and Egger's test showed that the articles had low publication bias. Network meta-analysis showed that the effect of NSPT in the No-DM group was significantly better than the WC-T2DM group [weighted mean difference (WMD) = 0.09, 95% confidence interval (CI) (0.01, 0.18)] and the PC-T2DM group [WMD = 0.09, 95% CI (0.01, 0.18)] in terms of CAL gain and better than the PC-T2DM group [WMD = 0.15, 95% CI (0.02, 0.28)] in terms of PD reduction. According to the surface under the cumulative ranking value, the No-DM group had the highest probability of achieving the best outcome following NSPT.

CONCLUSIONS

Collectively, our analyses show that T2DM exerts significant effects on the outcomes of NSPT.

Diagnostic value of HPV E6/E7 mRNA in screening for cervical intraepithelial neoplasia grade 2 or worse: A systematic review and meta‑analysis

Histology is considered the gold standard for diagnosing the pathological progress of cervical cancer development, while cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) is the cutoff for intervention in clinical practice. The diagnostic value of human papillomavirus (HPV) E6/E7 mRNA in screening for CIN2+ has not been systematically summarized. A meta-analysis was conducted as part of the present study conducted to explore the diagnostic value of HPV E6/E7 mRNA in screening for CIN2+, aiming to provide a new marker for earlier clinical diagnosis of cervical cancer. The PubMed, Embase and Cochrane Library databases were searched from inception to May 2023. Studies reporting the true positive, false positive, true negative and false negative values in differentiating between CIN2+ and CIN2- were included, while duplicate publications, studies without full text, incomplete information or inability to conduct data extraction, animal experiments, reviews and systematic reviews were excluded. STATA software was used to analyze the data. A total of 2,224 patients were included of whom there were 1,274 patients with CIN2+ and 950 patients with CIN2-. The pooled sensitivity and specificity of the studies overall were 0.89 (95% CI, 0.84-0.92) and 0.59 (95% CI, 0.46-0.71), respectively; the positive likelihood ratio (LR) and the negative LR of the studies overall were 2.31 (95% CI, 1.61-3.32) and 0.21 (95% CI, 0.14-0.30), respectively. The pooled diagnostic odds ratio of the studies overall was 11.53 (95% CI, 6.85-19.36). Additionally, the area under the curve was 0.88. The analysis indicated that HPV E6/E7 mRNA has high diagnostic efficacy for CIN2+. HPV E6/E7 mRNA is highly sensitive in the diagnosis of CIN2+, which helps to reduce the rate of missed diagnoses. However, lower specificity may lead to a higher number of misdiagnoses in healthy patients.

Is more always better? Effectiveness of constraint-induced movement therapy in children with high-risk or unilateral cerebral palsy (0-6 years): Systematic review and meta-analysis

BACKGROUND

While constraint-induced movement therapy is strongly recommended as an intervention for infants with unilateral cerebral palsy, the optimal dosage remains undefined. This systematic review aims to identify the most effective level of intensity of constraint-induced movement therapy to enhance manual function in infants at high risk of asymmetric brain lesions or unilateral cerebral palsy diagnosis.

METHODS

This systematic review with meta-analysis encompassed a comprehensive search across four electronic databases to identify articles that met the following criteria: randomised controlled trials, children aged 0-6 with at high risk or with unilateral cerebral palsy, and treatment involving constraint-induced movement therapy for upper limb function. Studies with similar outcomes were pooled by calculating the standardised mean difference score for each subgroup, and subgroups were stratified every 30 h of total intervention dosage (30-60, 61-90, >90 h). Risk of bias was assessed with Cochrane Collaboration's tool.

RESULTS

Seventeen studies were included. Meta-analyses revealed significant differences among subgroups. The 30-60 h subgroup showed a weak effect for spontaneous use of the affected upper limb during bimanual performance, grasp function, and parents' perception of how often children use their affected upper limb. Additionally, this subgroup demonstrated a moderate effect for the parents' perception of how effectively children use their affected upper limb.

CONCLUSIONS

Using a dosage ranging from 30 to 60 h when applying a constraint-induced movement therapy protocol holds promise as the most age-appropriate and cost-effectiveness approach for improving upper limb functional outcomes and parent's perception.

Effects of robotic rehabilitation using the Erigo® device on patients with neurological injury: a systematic review and meta-analysis of randomized clinical trials

OBJECTIVE

To systematically review the effects of robotic rehabilitation with the Erigo® device on patients with neurological injury on safety, spasticity, muscle strength, functionality, gait/balance, and changes in the level of consciousness.

METHODS

MEDLINE, SciELO, EMBASE, The Cochrane Library - CENTRAL and PEDro databases were consulted without the restriction of date and language. Randomized controlled trials that evaluated the robotic rehabilitation and compared it to conventional or placebo therapy, isolated or in association with other therapy, were selected. Studies in which the treatment time was less than 10 sessions were excluded. The risk of bias was assessed with the use of the RoB 2.0 tool.

RESULTS

Nine studies were included, totaling 347 patients. The robotic rehabilitation performed by the Erigo® device proved to be safe for neurological patients. The meta-analysis showed an improvement for spasticity (MD = 0.29; 95% CI = -0.49 to -0.08; I2 = 0%), but there was no significant increase in muscle strength in patients with stroke (MD = 0.25; CI 95% = -0.22 to -0,71; I2 = 0%). Erigo® showed inconclusive effects on functionality, gait/balance and level of consciousness in patients with severe acquired brain injury and vegetative or minimally conscious state. All studies present some concerns for the risk of bias.

CONCLUSION

Erigo® as a robotic rehabilitation strategy is safe for patients with acquired brain injury and appears to reduce spasticity in patients with stroke. The effects on muscle strength, functionality, gait and balance and level of consciousness remain uncertain and the methodological quality of the clinical trials included in this review is limited.

Perinatal outcomes following fetoscopic laser surgery for early twin-to-twin transfusion syndrome: Systematic review and meta-analysis

INTRODUCTION

Our objective was to investigate outcomes in twin-to-twin transfusion syndrome (TTTS) treated with fetoscopic laser surgery (FLS) at <18 weeks vs ≥18 weeks, and to conduct subgroup analysis of TTTS with FLS at <16 weeks vs 16-18 weeks.

MATERIAL AND METHODS

PubMed, Scopus and Web of Science were searched systematically from inception until May 2023. Primary outcome was survival, and secondary outcomes included preterm premature rupture of membranes (PPROM), preterm birth and gestational age (GA) at delivery.

RESULTS

Nine studies encompassing 1691 TTTS pregnancies were included. TTTS stage III was significantly more common in TTTS pregnancies treated with FLS at <18 weeks (odds ratio [OR] 2.84, 95% confidence interval [CI] 1.24-6.54), and procedure duration was shorter at <18 weeks (MD -5.27 minutes, 95% CI -9.19 to -1.34). GA at delivery was significantly earlier in TTTS pregnancies treated with FLS at <18 weeks (MD -3.12 weeks, 95% CI -6.11 to -0.13). There were no significant differences in outcomes, including PPROM, PPROM at <7 days post-FLS, preterm birth at <28 and <32 weeks, delivery at <7 days post-FLS, and survival outcomes, including fetal demise, live birth and neonatal survival. Similarly, TTTS stage III was more common in TTTS with FLS at <16 weeks than at 16-18 weeks (OR 2.95, 95% CI 1.62-5.35), with no significant differences in the aforementioned outcomes.

CONCLUSIONS

In early TTTS treated with FLS, outcomes were comparable between those treated at <18 weeks compared with ≥18 weeks except for GA at delivery, which was 3 weeks earlier. In the subset treated at <16 weeks vs 16-18 weeks, the procedure was feasible without an increased risk of very early preterm birth or perinatal mortality.

Insight into brain sex differences of typically developed infants and brain pathologies: A systematic review

The continually advancing landscape of neuroscientific and imaging research has broadened our comprehension of sex differences encoded in the human brain, expanding from the hypothalamus and sexual behaviour to encompass the entire brain, including its diverse lobes, structures, and functions. However, less is known about sex differences in the brains of neonates and infants, despite their relevance to various sex-linked diseases that develop early in life. In this review, we provide a synopsis of the literature evidence on sex differences in the brains of neonates and infants at the morphological, structural and network levels. We also briefly overview the present evidence on the sex bias in some brain disorders affecting infants and neonates.

Part II: animal trials

Background

Bone ring (BR) grafts have been introduced to reconstruct alveolar ridge defects with simultaneous implant placement, but their clinical effectiveness remains undetermined. The aim of the current systematic review was to critically appraise evidence from animal studies regarding the effectiveness of BR grafts in alveolar ridge reconstruction and their variations under different surgical protocols.

Methods

Electronic retrieval of six databases (MEDLINE, Embase, Cochrane Library, ScienceDirect, Web of Science, and Scopus) and citation search until 11 October 2023, for animal studies on bone augmentation employing BR grafts. The outcome variables were total bone area (BA), bone volume (BV), bone-implant contact (BIC), and histology. The protocol was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and prospectively registered with PROSPERO (CRD42023453949).

Results

Ten studies were included in the qualitative analysis according to the screening criteria. Two studies demonstrated favorable bone remodeling and osseointegration of the BR with both the implant and pristine bone. A comparative study between autogenous BRs and allogenic BRs reported a higher percentage of BA and BIC at 4 months of healing, but conflicting data were observed at 8 months. Another study indicated a significant advantage of autogenous BRs over bovine and biphasic ceramic BRs in terms of BA and BIC after 5 weeks. Three studies found that using collagen membranes did not significantly affect BA, BV, or BIC when used simultaneously with autogenous BRs during implant placement. Two studies evaluated one-stage and two-stage implant placement in conjunction with BR grafts, revealing similar levels of BA, BV, and BIC except for differences in total treatment time. Furthermore, one study found that the use of mucogingival junction incision and split-thickness flap significantly reduced the incidence of wound dehiscence compared with conventional incision and flap.

Conclusions

Vertical bone augmentation surgery utilizing BR grafts with one-stage implant placement yielded histological and histomorphometric outcomes comparable to those achieved with two-stage implant placement or the additional application of collagen membrane.

Key performance indicators to inform evaluation of wound care programmes for people with complex wounds: a protocol for systematic review

OBJECTIVE

The objective of the systematic review is to examine and summarise the available evidence in the literature of the use of key performance indicators (KPIs) to inform evaluation of wound care programmes and services for people with hard-to-heal (complex) wounds. The need for wound care is expected to grow with the continued ageing of the population and the resulting increased development of chronic conditions. This expected increase necessitates improvement of wound care programmes and services and their ability to deliver quality, evidence-based and cost-effective practice. The current literature lacks a systematic assessment of KPIs to inform evaluation of wound care services and programmes across various settings, and how the KPIs are used to improve the quality of wound care and achieve desired outcomes. This protocol sets out how the systemtic review will be undertaken.

METHOD

Primary studies will be screened from databases such as MEDLINE, CINAHL and Scopus, with unpublished studies and grey literature retrieved from Google Scholar and ProQuest Dissertations and Theses. The study titles and abstracts will be screened by two independent reviewers, using Covidence systematic review software to ensure they meet the inclusion criteria, who will then proceed with data extraction of the full-text using the standardised data extraction instrument. The reference lists of all studies selected for critical appraisal will be screened for additional publications. The two independent reviewers will critically appraise all studies undergoing full-text data extraction using the appropriate checklist from JBI SUMARI. At all stages, differences between reviewers will be resolved through discussion, with adjudication by a third, independent reviewer.

RESULTS

Data points will be analysed with descriptive statistics and grouped, based on programme characteristics and publication status. Grey literature and peer-reviewed publications will form separate analyses. To answer review questions, the data will be summarised in a narrative format. A meta-analysis is not planned. At the time of writing, this protocol has been implemented up to the preliminary literature search.

CONCLUSION

This review will address a current literature gap and systematically identify KPIs in wound care, allowing for programmes to evaluate their quality of care and improve their services in a methodical manner.

Spontaneous activity in peripheral sensory nerves: a systematic review

ABSTRACT

In the peripheral nervous system, spontaneous activity in sensory neurons is considered to be one of the 2 main drivers of chronic pain states, alongside neuronal sensitization. Despite this, the precise nature and timing of this spontaneous activity in neuropathic pain is not well-established. Here, we have performed a systematic search and data extraction of existing electrophysiological literature to shed light on which fibre types have been shown to maintain spontaneous activity and over what time frame. We examined both in vivo recordings of preclinical models of neuropathic pain, as well as microneurography recordings in humans. Our analyses reveal that there is broad agreement on the presence of spontaneous activity in neuropathic pain conditions, even months after injury or years after onset of neuropathic symptoms in humans. However, because of the highly specialised nature of the electrophysiological methods used to measure spontaneous activity, there is also a high degree of variability and uncertainty around these results. Specifically, there are very few directly controlled experiments, with less directly comparable data between human and animals. Given that spontaneous peripheral neuron activity is considered to be a key mechanistic feature of chronic pain conditions, it may be beneficial to conduct further experiments in this space.

Volumetric alterations in the basal ganglia in autism Spectrum disorder: A systematic review

INTRODUCTION

Recent research indicates that some brain structures show alterations in conditions such as Autism Spectrum Disorder (ASD). Among them, are the basal ganglia that are involved in motor, cognitive and behavioral neural circuits.

OBJECTIVE

Review the literature that describes possible volumetric alterations in the basal ganglia of individuals with ASD and the impacts that these changes have on the severity of the condition.

METHODOLOGY

This systematic review was registered in the design and reported according to the PRISMA Items and registered in PROSPERO (CRD42023394787). The study analyzed data from published clinical, case-contemplate, and cohort trials. The following databases were consulted: PubMed, Embase, Scopus, and Cochrane Central Register of Controlled Trials, using the Medical Subject Titles (MeSH) "Autism Spectrum Disorder" and "Basal Ganglia". The last search was carried out on February 28, 2023.

RESULTS

Thirty-five eligible articles were collected, analyzed, and grouped according to the levels of alterations.

CONCLUSION

The present study showed important volumetric alterations in the basal ganglia in ASD. However, the examined studies have methodological weaknesses that do not allow generalization and correlation with ASD manifestations.

The effects of pomegranate consumption on blood pressure in adults: A systematic review and meta-analysis

Considering the main component of cardiovascular disease and due to the high prevalence of hypertension, controlling blood pressure is required in individuals with various health conditions. Randomized clinical trials (RCTs) which studied the effects of pomegranate consumption on blood pressure have shown inconsistent findings. As a result, we intended to assess the effects of pomegranate consumption on systolic (SBP) and diastolic (DBP) blood pressure in adults. Systematic literature searches up to January 2024 were carried out using electronic databases, including PubMed, Web of Science, and Scopus, to identify eligible RCTs assessing the effects of pomegranate on blood pressure as an outcome. All the individuals who took part in our research were adults who consumed pomegranate in different forms as part of the study intervention. Heterogeneity tests of the selected trials were performed using the I2 statistic. Random effects models were assessed based on the heterogeneity tests, and pooled data were determined as the weighted mean difference (WMD) with a 95% confidence interval (CI). Of 2315 records, 22 eligible RCTs were included in the current study. Our meta-analysis of the pooled findings showed that pomegranate consumption significantly reduced SBP (WMD: -7.87 mmHg; 95% CI: -10.34 to -5.39; p < 0.001) and DBP (WMD: -3.23 mmHg; 95% CI: -5.37 to -1.09; p = 0.003). Individuals with baseline SBP > 130 mmHg had a significantly greater reduction in SBP compared to individuals with baseline SBP < 130 mmHg. Also, there was a high level of heterogeneity among studies (SBP: I2 = 90.0% and DBP: I2 = 91.8%). Overall, the results demonstrated that pomegranate consumption lowered SBP and DBP in adults. Although our results suggest that pomegranate juice may be effective in reducing blood pressure in the pooled data, further high-quality studies are needed to demonstrate the clinical efficacy of pomegranate consumption.

Effects of avoidance versus use of neuromuscular blocking agents for facilitation of tracheal intubation in children and infants

BACKGROUND

The European Society of Anesthesiology and Intensive Care recommends the use of neuromuscular blocking agents (NMBA) in adults, to facilitate tracheal intubation and reduce its associated complications. Children who undergo tracheal intubation may suffer some of the same complications, however, no consensus exists regarding the use of NMBA for tracheal intubation in the pediatric population. We will explore the existing evidence assessing the effects of avoidance versus the use of NMBA for the facilitation of tracheal intubation in children and infants.

METHODS

This protocol follows the preferred reporting items for systematic reviews and meta-analyses protocols recommendations. We will include all randomized controlled clinical trials assessing the effects of avoidance versus the use of NMBA for facilitation of tracheal intubation (oral or nasal) using direct laryngoscopy or video laryngoscopy in pediatric participants (<18 years). Our primary outcome is incidence of difficult tracheal intubation. Secondary outcomes include incidence of serious adverse events, failed intubation, events of upper airway discomfort or injury, and difficult laryngoscopy. We will conduct a thorough database search to identify relevant trials, including CENTRAL, MEDLINE, EMBASE, BIOSIS, Web of Science, CINAHL, and trial registries. Two review authors will independently handle the screening of literature and data extraction. Each trial will be evaluated for major sources of bias with the "classic risk of bias tool" used in the Cochrane Collaboration tool from 2011. We will use Review manager (RevMan) or R with the meta package to perform the meta-analysis. We will perform a trial sequential analysis on the meta-analysis of our primary outcome, providing an estimate of statistical reliability. Two review authors will independently assess the quality of the body of evidence using the grading of recommendations assessment, development, and evaluation (GRADE) approach. We will use GRADEpro software to conduct the GRADE assessments and to create "Summary of the findings" tables.
