Low serum hepcidin levels in women with polycystic ovary syndrome: evidence from meta-analysis

BACKGROUND

Iron metabolism plays a significant role in the development of metabolic disorders in women with polycystic ovary syndrome (PCOS). Despite the importance of hepcidin, a key iron regulator, current research on serum hepcidin levels in PCOS patients shows conflicting results.

METHODS

PubMed, Embase, Web of Science, Cochrane Library and the China National Knowledge Infrastructure (CNKI) database were systematically searched from their inception to 9 September 2023. The search aimed to identify studies in English and Chinese that examined hepcidin levels in women with PCOS compared to healthy control subjects. Standardized mean differences (SMDs) with corresponding 95% confidence intervals (95% CIs) were calculated to evaluate the difference in serum hepcidin levels between women with and without PCOS.

RESULTS

The meta-analysis included a total of 10 eligible studies, which encompassed 499 PCOS patients and 391 control subjects. The pooled analysis revealed a significant reduction in serum hepcidin levels among the PCOS patients compared to the healthy controls (SMD = -3.49, 95% CI: -4.68 to -2.30, p < .05). There was no statistically significant difference in serum hepcidin levels between PCOS patients with a body mass index (BMI) < 25 and those with a BMI ≥ 25 (p > .05).

CONCLUSION

The serum hepcidin levels of women with PCOS were significantly lower than those of healthy controls, which suggests that serum hepcidin could be a potential biomarker for PCOS.

Fermented Ophiocordyceps sinensis mycelium products for preventing contrast-associated acute kidney injury: a systematic review of randomized controlled trials

BACKGROUND

To evaluate the efficacy, effectiveness and safety of fermented Ophiocordyceps sinensis mycelium (FOSM) products for preventing contrast-associated acute kidney injury (CA-AKI).

METHODS

Randomized controlled trials were searched from four Chinese and four English electronic databases and three clinical trial registries up to July 2023. Methodological quality was assessed by using the Cochrane risk-of-bias tool 2.0. Risk difference (RD) or risk ratio (RR) and mean difference (MD) were calculated along with the 95% confidence intervals (CIs).

RESULTS

Fourteen trials testing three types of FOSM products (Bailing, Zhiling, and Jinshuibao capsules) involving 1271 participants injected contrast agents were included. For the risk of bias, all trials were rated as some concerns. Compared with routine preventive procedure (RPP) (saline hydration and alprostadil), FOSM products plus RPP showed beneficial effects in reducing the incidence of CA-AKI (14.62% and 5.35%, respectively; RD -0.06, 95% CI -0.09 to -0.03). Subgroup analysis showed that Bailing/Jinshuibao plus RPP demonstrated lower incidence of CA-AKI compared to RPP. However, there was no statistically significant difference between Zhiling with RPP and RPP in the incidence of CA-AKI. Additionally, only when FOSM products were taken before injection of the contrast, it was superior to RPP in reducing the incidence of CA-AKI. There was no statistical difference in adverse events between these two groups.

CONCLUSIONS

Low certainty evidence suggests that preventive oral use of FOSM products as an adjuvant agent was safe and might decrease the incidence of CA-AKI. However, high-quality placebo-controlled trials are needed to confirm its benefit.

The global seroprevalence of Toxoplasma gondii infection in workers occupationally exposed to animals (1972-2023): a systematic review and meta-analysis

Toxoplasma gondii, a ubiquitous zoonotic parasite infecting warm-blooded animals, poses a significant health threat to workers with occupational animal exposure (WOEA) due to their frequent contact with potential reservoirs. Existing data on T. gondii seroprevalence in the WOEA exhibits substantial global variation. This systematic review and meta-analysis, adhering to PRISMA guidelines, aimed to quantify the global seroprevalence of T. gondii infection among WOEA over the past five decades (1972-2023). We identified 66 eligible studies through a comprehensive search strategy encompassing English publications, with a total sample size of 15,279. A random-effects model with the Freeman-Tukey transformation in STATA v16.0 accounted for the high heterogeneity observed. We estimated the pooled global seroprevalence of T. gondii infection in WOEA at 41% (95% CI: 36-47%). Subgroup analyses revealed significant variations by gender: males (63%) vs. females (37%) (p < 0.05), occupation: non-livestock workers (54%), livestock workers (47%), slaughterhouse workers (44%), and veterinary personnel (27%) (p < 0.05). Geographic trends showed the highest prevalence in Africa (51%), followed by South America (49%), Europe (47%), Australia (43%), Asia (36%), and North America (23%; p < 0.05). Lower prevalence was observed in high-income (39%) and upper-middle-income (38%) countries compared to lower-middle-income (44%) and low-income (48%) countries (p < 0.05). This analysis underscores the high global seroprevalence of T. gondii in the WOEA, highlighting the need for targeted interventions in this high-risk population.

Efficacy of astragalus combined with renin-angiotensin-aldosterone system blockers in the treatment of stage III diabetic nephropathy: a systematic review and meta-analysis

OBJECTIVE

To determine the efficacy and safety of Astragalus combined with renin-angiotensin-aldosterone system (RAAS) blockers in treating stage III diabetic nephropathy (DN) by meta-analysis.

METHODS

PubMed, Embase, Cochrane Library, Wiley, and Web of Science databases were searched for articles published between August 2007 and August 2022. Clinical studies on Astragalus combined with RAAS blockers for the treatment of stage III DN were included. Meta-analysis was performed by RevMan 5.1 and Stata 14.3 software.

RESULTS

A total of 32 papers were included in this meta-analysis, containing 2462 patients from randomized controlled trials, with 1244 receiving the combination treatment and 1218 solely receiving RAAS blockers. Astragalus combined with RAAS blockers yielded a significantly higher total effective rate (TER) (mean difference [MD] 3.63, 95% confidence interval [CI] 2.59-5.09) and significantly reduced urinary protein excretion rate (UPER), serum creatinine (Scr), blood urine nitrogen (BUN) and glycosylated hemoglobin (HbAlc) levels. In subgroup analysis, combining astragalus and angiotensin receptor blocker significantly lowered fasting plasma glucose (FPG) and 24 h urinary protein (24hUTP) levels, compared with the combined astragalus and angiotensin-converting enzyme inhibitor treatment. Meanwhile, the latter significantly decreased the urinary microprotein (β2-MG). Importantly, the sensitivity analysis confirmed the study's stability, and publication bias was not detected for UPER, BUN, HbAlc, FPG, or β2-MG. However, the TER, SCr, and 24hUTP results suggested possible publication bias.

CONCLUSIONS

The astragalus-RAAS blocker combination treatment is safe and improves outcomes; however, rigorous randomized, large-scale, multi-center, double-blind trials are needed to evaluate its efficacy and safety in stage III DN.

Meta-analysis of efficacy and safety of pembrolizumab for the treatment of advanced or recurrent cervical cancer

BACKGROUND

This meta-analysis seeks to assess the efficacy and safety of pembrolizumab in individuals with advanced or recurrent cervical cancer.

METHODS

Databases from PubMed, Embase, and the Cochrane Library were all thoroughly searched for pertinent research. Outcomes include complete response (CR), partial response (PR), stable disease (SD), disease progression (PD), overall response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), median overall survival (mOS), and adverse events (AEs) were retrieved for further analysis.

RESULTS

Ten trials with 721 patients were included in this meta-analysis. The pooled results for patients with cervical cancer receiving pembrolizumab were as follows: CR (0.06, 95%CI: 0.02-0.10), PR (0.15, 95%CI: 0.08-0.22), SD (0.16, 95%CI: 0.13-0.20), PD (0.50, 95%CI: 0.25-0.75), ORR (0.26, 95%CI: 0.11-0.41) and DCR (0.42, 95%CI: 0.13-0.71), respectively. Regarding survival analysis, the pooled mPFS and mOS were 3.81 and 10.15 months. Subgroup analysis showed that pembrolizumab in combination was more beneficial in CR (0.16 vs. 0.03, p = 0.012), PR (0.24 vs. 0.08, p = 0.032), SD (0.11 vs. 0.19, p = 0.043), ORR (0.42 vs. 0.11, p = 0.014), and mPFS (5.54 months vs. 2.27 months, p < 0.001) than as single agent. The three most common AEs were diarrhoea (0.25), anaemia (0.25), and nausea (0.21), and the incidence of grade 3-5 AEs was significantly lower, rarely surpassing 0.10.

CONCLUSIONS

For patients with advanced or recurrent cervical cancer, this systematic review and meta-analysis demonstrated that pembrolizumab had a favourable efficacy and tolerability. Future research will primarily focus on optimising customised regiments that optimally integrate pembrolizumab into new therapies and combination strategies. Designed to maximise patient benefit and efficiently control adverse effects while maintaining a high standard of living.

Elucidation of critical chemical moieties of metallo-β-lactamase inhibitors and prioritisation of target metallo-β-lactamases

The urgent demand for effective countermeasures against metallo-β-lactamases (MBLs) necessitates development of novel metallo-β-lactamase inhibitors (MBLIs). This study is dedicated to identifying critical chemical moieties within previously developed MBLIs, and critical MBLs should serve as the target in MBLI evaluations. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), a systematic literature analysis was conducted, and the NCBI RefSeq genome database was exploited to access the abundance profile and taxonomic distribution of MBLs and their variant types. Through the implementation of two distinct systematic approaches, we elucidated critical chemical moieties of MBLIs, providing pivotal information for rational drug design. We also prioritised MBLs and their variant types, highlighting the imperative need for comprehensive testing to ensure the potency and efficacy of the newly developed MBLIs. This approach contributes valuable information to advance the field of antimicrobial drug discovery.

Therapeutic effects of acupuncture therapy for kidney function and common symptoms in patients with chronic kidney disease: a systematic review and meta-analysis

Purpose: The number of clinical reports of acupuncture therapy in chronic kidney disease (CKD) is gradually increasing. This systematic review and meta-analysis aim to examine the therapeutic role of acupuncture therapy in kidney function and common symptoms in CKD patients.Methods: We searched Embase, PubMed, Scopus, Web of Science, China National Knowledge Infrastructure, WanFang, and WeiPu for randomized controlled trials comparing acupuncture treatment with control or placebo groups. We assessed the effect of acupuncture therapy in CKD patients using a meta-analysis with the hartung-knapp-sidik-jonkman random effects model. In addition, we visualized keyword co-occurrence overlay visualization with the help of VOSviewer software to describe the research hotspots of acupuncture therapy and CKD.Results: A total of 24 studies involving 1494 participants were included. Compared to the control group, acupuncture therapy reduced serum creatinine levels (standardized mean difference [SMD]: -0.57; 95% CI -1.05 to -0.09) and relieved pruritus (SMD: -2.20; 95% CI -3.84, -0.57) in patients with CKD, while the TSA showed that the included sample size did not exceed the required information size. The included studies did not report acupuncture-related adverse events.Conclusions: Acupuncture is an effective and safe treatment for improving kidney function and relieving pruritic symptoms in patients with CKD, but the very low evidence may limit this conclusion. The TSA suggests that high-quality trials are needed to validate the efficacy of acupuncture therapy.

Management of primary snoring in adults: A scoping review examining interventions, outcomes and instruments used to assess clinical effects

While various treatment options for primary snoring are available, evidence-based recommendations to determine the optimal intervention remain unestablished. To inform future directions of research to guide clinical decision-making, this scoping review was conducted to map the existing evidence on interventions for primary snoring, the outcomes and instruments used to assess their clinical effects in adults. The feasibility of conducting further systematic reviews and comparing outcomes across these therapies using network meta-analysis was also assessed. Of the 1673 records identified, 38 interventional studies met the inclusion criteria with three-fifths of them being before-after studies. The most common reason for study exclusion was results being reported for patients with primary snoring and obstructive sleep apnoea (OSA) combined. Interventions were surgical (73 %), behavioural and the use of devices/medications. Twenty-six common outcomes were identified and categorised into six domains. Fifty-nine instruments were used to assess the outcomes and based mainly on non-validated questionnaires. Our findings indicated (1) the need for randomised controlled trials with strict discrimination between patients with primary snoring and OSA, (2) further network meta-analyses using some outcomes is feasible, and (3) a core outcome set to inform standardised reporting for future research should be developed.

Cognitive behavioral therapy for insomnia in people with chronic musculoskeletal pain. A systematic review and dose-response meta-analysis

The aims were (i) to determine the effects of Cognitive behavioral therapy for insomnia (CBT-I) on sleep disturbances, pain intensity and disability in patients with chronic musculoskeletal pain (CMP), and (ii) to determine the dose-response association between CBT-I dose (total minutes) and improvements in sleep disorders, pain intensity and disability in patients with CMP. A comprehensive search was conducted in PubMed/MEDLINE, Web of Science, CINAHL, and SCOPUS until December 17, 2023. Randomized clinical trials (RCTs) using CBT-I without co-interventions in people with CMP and sleep disorders were eligible. Two reviewers independently extracted data and assessed risk of bias and certainty of the evidence. A random effects meta-analysis was applied to determine the effects on the variables of interest. The dose-response association was assessed using a restricted cubic spline model. Eleven RCTs (n = 1801 participants) were included. We found a significant effect in favor of CBT-I for insomnia (SMD: -1.34; 95%CI: -2.12 to -0.56), with a peak effect size at 450 min of CBT-I (-1.65, 95%CI: -1.89 to -1.40). A non-significant effect was found for pain intensity. A meta-analysis of disability was not possible due to the lack of data. This review found benefits of CBT-I for insomnia compared to control interventions, with a large effect size. In addition, it was estimated that a 250-min dose of CBT-I had a large effect on reducing insomnia and that the peak effect was reached at 450 min. These novel findings may guide clinicians in optimizing the use of CBT-I in people with CMP and insomnia.

Biocultural heritage of the Caatinga: a systematic review of Myrtaceae and its multiple uses

The Caatinga, an exclusively Brazilian biome, stands as a reservoir of remarkable biodiversity. Its significance transcends ecological dimensions, given the direct reliance of the local population on its resources for sustenance and healthcare. While Myrtaceae, a pivotal botanical family within the Brazilian flora, has been extensively explored for its medicinal and nutritional attributes, scant attention has been directed towards its contextual relevance within the Caatinga's local communities. Consequently, this inaugural systematic review addresses the ethnobotanical roles of Myrtaceae within the Caatinga, meticulously anchored in the PRISMA 2020 guidelines. We searched Scopus, MEDLINE/Pubmed, Scielo, and LILIACS. No date-range filter was applied. An initial pool of 203 articles was carefully scrutinized, ultimately yielding 31 pertinent ethnobotanical studies elucidating the utility of Myrtaceae amongst the Caatinga's indigenous populations. Collectively, they revealed seven distinct utilization categories spanning ~54 species and 11 genera. Psidium and Eugenia were the genera with the most applications. The most cited categories of use were food (27 species) and medicinal (22 species). The importance of accurate species identification was highlighted, as many studies did not provide enough information for reliable identification. Additionally, the potential contribution of Myrtaceae fruits to food security and human health was explored. The diversity of uses demonstrates how this family is a valuable resource for local communities, providing sources of food, medicine, energy, and construction materials. This systematic review also highlights the need for more ethnobotanical studies to understand fully the relevance of Myrtaceae species in the Caatinga, promoting biodiversity conservation, as well as support for local populations.

Platelet-rich plasma for de Quervain’s tenosynovitis: A systematic review and meta-analysis

BACKGROUND

Platelet-rich plasma (PRP) injection is used as an alternative non-operative management for de Quervain’s tenosynovitis (DQT) to regenerate tendon healing.

AIM

To assess and conclude the research-based study systematically to analyse the efficacy of PRP on DQT.

METHODS

This systematic review used the Cochrane Handbook for Systematic Reviews and the guideline of preferred reporting items for systematic review and meta-analysis. A systematic literature search was applied to 11 databases. The authors assessed the study quality and risk of bias of each included study. Results of the meta-analysis were presented using mean difference (MD)/standardized mean difference (SMD) and 95% confidence interval (CI).

RESULTS

The authors evaluated 275 studies found in the literature search; 12 studies met the criteria for this review, and then the study quality and risk of bias were assessed. Pooled analysis of data from two studies involving 194 subjects with DQT showed that, compared with conservative treatment, PRP injection was associated with a greater reduction in visual analog scale pain in one month and six months after treatment (MD: -0.67, P value < 0.00001; MD: -1.16, P value < 0.00001) and the increase of Mayo’s wrist score in one month and six months after treatment (SMD: 3.72, P value < 0.00001; SMD: 4.44, P value < 0.00001).

CONCLUSION

PRP can be used as an alternative non-operative treatment for DQT due to the tissue regenerative effect of PRP.

Impact of Biological Sex on Emotional Perception Among Adults With Schizophrenia Spectrum Disorders: Protocol for a Systematic Review

BACKGROUND

It is well established that individuals with schizophrenia experience deficits in emotional perception that can impact long-term social and occupational functioning. Understanding the factors that impact these impairments is important for targeting interventions to improve recovery. In the general population, compared with males, females tend to show greater perception of emotions. Whether this sex difference persists in schizophrenia is less clear. In contrast to males, females diagnosed with schizophrenia tend to have a higher age of disease onset and better premorbid functioning but do not necessarily have better outcomes. Effective treatments for social cognitive impairments are highly relevant to long-term functional rehabilitation. A greater understanding of the cognitive deficits in emotional perception within females and males living with schizophrenia may assist interventions to be better tailored to individuals.

OBJECTIVE

This systematic review aims to collate, synthesize, and critically appraise evidence considering the influence of biological sex (female and male) on the emotional perception of individuals with schizophrenia.

METHODS

This is a systematic review protocol based on the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols) guidelines. The electronic databases MEDLINE, Embase, CENTRAL, CINAHL, and PsycINFO will be systematically searched. To be included in this review, studies must compare the emotional perceptions of male and female participants older than 18 years who have a primary diagnosis of a schizophrenia spectrum disorder. Qualitative studies, case reports, case series, unpublished manuscripts, and studies not reported in English will be excluded. Key search strategies will include combinations of the following terms: "men," "male," "man," "female," "women," "woman," "sex," "gender," "emotional perception," "emotional processing," "schizophrenia," "schizophren," "psychotic disorders," "psychosis," "psychoses," "psychotic," "schizoaffective," "schizotypal personality disorder," and "schizotyp." Identified studies will be uploaded to the web-based Covidence systematic review management software. The risk of bias for individual studies will be assessed using the relevant Joanna Briggs Institute checklist tools. The GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system will also be used to evaluate the strength of the evidence base. Findings will be synthesized to provide a systematic summary of the existing literature. If sufficiently comparable data to permit meta-analysis emerges, a random-effects meta-analysis will be performed.

RESULTS

This systematic review was registered with the PROSPERO (International Prospective Register of Systematic Reviews) in October 2023. The search and screening of study titles and abstracts are currently underway. Data are expected to be extracted and analyzed in July 2024.

CONCLUSIONS

Results will contribute to an improved understanding of the social cognitive profiles of males and females with schizophrenia. This knowledge is expected to inform the adaptation of interventions to improve functional outcomes.

N-of-1 trials in epilepsy: A systematic review and lessons paving the way forward

OBJECTIVE

Defined as prospective single-patient crossover studies with repeated paired cycles of active and control intervention, N-of-1 trials have gained attention as an option to obtain high-quality evidence of efficacy, particularly for patients with rare epilepsies in whom conduction of well-powered randomized controlled trials can be challenging. The objective of this systematic review is to provide an appraisal of the literature on N-of-1 trials in individuals with epilepsy.

METHODS

We searched PubMed and Embase on January 12, 2024, for studies meeting the following criteria: prospectively planned, within-patient, multiple-crossover design in individuals with epilepsy and outcomes related to comorbidities. Information on design, outcome measurements, intervention, and analyses was retrieved. Risk of bias assessment was performed using the Risk of Bias in N-of-1 Trials (RoBiNT) scale. We highlighted methodological aspects of the N-of-1 trials identified and discuss future recommendations.

RESULTS

Five studies met our inclusion criteria. An additional multiple-crossover trial that evaluated treatment effects exclusively at group level was also included because of its relevance to N-of-1 study methodology. The studies enrolled individuals with focal seizures, absences or cognitive impairement and electrographic discharges. Treatments included established or investigational antiseizure medications, off-label medications, neurostimulation or lifestyle intervention. Three of the five N-of-1 trials reported on individual cases. The studies' strengths were the use of individualized treatment dosages and symptom-specific patient-reported outcomes. Limitations were related to minimal reporting of baseline characteristics and seizure burden.

SIGNIFICANCE

The trials identified by our search exemplify how the N-of-1 design can be applied to assess interventions in individuals with epilepsy-related disorders. Future N-of-1 trials of antiseizure interventions should take into account baseline seizure frequency, should apply statistical models suited to capture seizure frequency changes reliably and make predefined interim assessments. Non-seizure outcome measures evaluable over short periods should be considered. Tailored N-of-1 methodology could pave the way to evidence-based, treatment selection for patients with rare epilepsies.

Neural bases of reading fluency: A systematic review and meta-analysis

Reading fluency, the ability to read quickly and accurately, is a critical marker of successful reading and is notoriously difficult to improve in reading disabled populations. Despite its importance to functional literacy, fluency is a relatively under-studied aspect of reading, and the neural correlates of reading fluency are not well understood. Here, we review the literature of the neural correlates of reading fluency as well as rapid automatized naming (RAN), a task that is robustly related to reading fluency. In a qualitative review of the neuroimaging literature, we evaluated structural and functional MRI studies of reading fluency in readers from a range of skill levels. This was followed by a quantitative activation likelihood estimate (ALE) meta-analysis of fMRI studies of reading speed and RAN measures. We anticipated that reading speed, relative to untimed reading and reading-related tasks, would harness ventral reading pathways that are thought to enable the fast, visual recognition of words. The qualitative review showed that speeded reading taps the entire canonical reading network. The meta-analysis indicated a stronger role of the ventral reading pathway in rapid reading and rapid naming. Both reviews identified regions outside the canonical reading network that contribute to reading fluency, such as the bilateral insula and superior parietal lobule. We suggest that fluent reading engages both domain-specific reading pathways as well as domain-general regions that support overall task performance and discuss future avenues of research to expand our understanding of the neural bases of fluent reading.

Efficacy and Safety of Testosterone Replacement in Testicular Cancer Survivors With Treatment-Influenced Hypogonadism: A Systematic Review

OBJECTIVE

The objective is to evaluate the efficacy and safety of testosterone supplementation in testicular cancer survivors with treatment-related hypogonadism.

DATA SOURCES

This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards and used Embase, PubMed/MEDLINE, Cochrane Central, Web of Science Core Collection, Korean Journal Index, SciELO, and Global Index Medicus to obtain data in June of 2024.

STUDY SELECTION AND DATA EXTRACTION

Analyses evaluating testosterone supplementation in testicular cancer survivors with treatment-induced hypogonadism were included. Any analyses not assessing supplementation in this population or deemed unretrievable were excluded.

DATA SYNTHESIS

Ten analyses were included for analysis. A total of 332 bilateral or unilateral testicular cancer survivors with treatment-influenced hypogonadism were reviewed, with 238 patients receiving testosterone replacement. Eight of the 10 analyses assessed participants without poor quality-of-life (QOL) metrics, metabolic factors, and bone mineral density (BMD) at baseline and only found a significant benefit in fat distribution metrics with testosterone supplementation. Two analyses evaluated participants with poor QOL metrics or BMD at baseline and showed improvements in QOL or BMD with testosterone supplementation.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE

There is robust evidence regarding the efficacy and safety of testosterone replacement in hypogonadal individuals but limited evidence specifically evaluating supplementation in testicular cancer survivors with treatment-influenced hypogonadism.

CONCLUSIONS

The results suggest testosterone replacement may be beneficial in patients with impaired QOL metrics, metabolic factors, and BMD at baseline; the results also suggest that routine supplementation for all individuals in this patient population lacks efficacy.

Stem cell-derived extracellular vesicles in premature ovarian failure: an up-to-date meta-analysis of animal studies

BACKGROUND

There has been a significant surge in animal studies of stem cell-derived extracellular vesicles (EVs) therapy for the treatment of premature ovarian failure (POF) but its efficacy remains unknown and a comprehensive and up-to-date meta-analysis is lacking. Before clinical translation, it is crucial to thoroughly understand the overall impact of stem cell-derived EVs on POF.

METHODS

PubMed, EMBASE, Cochrane Library, Web of Science were searched up to February 18, 2024. The risk of bias was evaluated according to Cochrane Handbook criteria, while quality of evidence was assessed using the SYRCLE system. The PRISMA guidance was followed. Trial sequential analysis was conducted to assess outcomes, and sensitivity analysis and publication bias analysis were performed using Stata 14.

RESULTS

Data from 25 studies involving 339 animals were extracted and analyzed. The analysis revealed significant findings: stem cell-derived EVs increase ovary weight (SMD = 3.88; 95% CI: 2.50 ~ 5.25; P < 0.00001; I2 = 70%), pregnancy rate (RR = 3.88; 95% CI: 1.94 ~ 7.79; P = 0.0001; I2 = 0%), count of births (SMD = 2.17; 95% CI: 1.31 ~ 3.04; P < 0.00001; I2 = 69%) and counts of different types of follicles. In addition, it elevates the level of AMH (SMD = 4.15; 95% CI: 2.75 ~ 5.54; P < 0.00001; I2 = 88%) and E2 (SMD = 2.88; 95% CI: 2.02 ~ 3.73; P < 0.00001; I2 = 80%) expression, while reducing FSH expression (SMD = -5.05; 95% CI: -6.60 ~ -3.50; P < 0.00001; I2 = 90%). Subgroup analysis indicates that the source of EVs, animal species, modeling method, administration route, and test timepoint affected efficacy. Trial sequential analysis showed that there was sufficient evidence to confirm the effects of stem cell-derived EVs on birth counts, ovarian weights, and follicle counts. However, the impact of stem cell-derived EVs on pregnancy rates needs to be further demonstrated through more animal experimental evidence.

CONCLUSIONS

Stem cell-derived EVs demonstrate safety and efficacy in treating POF animal models, with potential improvements in fertility outcomes.

Evidence library of meta-analytical literature assessing the sustainability of agriculture - a dataset

In the last two decades, an exponentially growing number of meta-analyses (MAs) synthesize thousands of peer-reviewed studies on the environmental impacts of farming practices (FPs). This paper describes the iMAP-FP evidence library, a comprehensive dataset on the effects of 34 categories of FPs (such as agronomic practices, cropping and livestock systems, land management options and mitigation techniques) on 34 impacts including climate mitigation, soil health, environmental pollution, water use, nutrients cycling, biodiversity, and agricultural productivity. Through systematic screening, 570 MAs published since 2000 were selected and categorized according to the type of FP. We assessed their impacts, the geographic regions covered, and their quality. We extracted 3,811 effects and their statistical significance associated with sustainable FPs (intervention) compared to a control (typically conventional agriculture) across 223 different intervention-control pairs. Our dataset is accompanied with an online free-access library, which includes a catalogue of synthetic reports summarizing the available evidence on each evaluated FP.

An Integrative Review of the Literature Examining Sexual Relationship Power, Depressive Symptoms, Silencing the Self, and HIV Vulnerability for Women in the United States

ABSTRACT

The purpose of our integrative review was to synthesize the literature examining relationships between depressive symptoms, silencing the self (STS), sexual relationship power (SRP), and HIV vulnerability among women in the United States. Literature searches were conducted through CINAHL, MEDLINE, PsycINFO, SCOPUS, Sociological Abstracts, and SocINDEX. Integrative review methodology of Whittemore and Knafl guided the review process, and 37 articles met inclusion criteria. The Theory of Gender and Power, modified by Wingood and DiClemente, was the guiding framework to organize and synthesize findings. Primary findings suggest that depressive symptoms, STS, and SRP in relationships may individually influence women's vulnerability for acquiring HIV, yet research lags behind. Evidence documenting relationships between these factors is insufficient to draw generalizable conclusions. Findings suggest that the current literature on this topic does not reflect those women most highly affected by HIV and those who identify as African American or Black in the Southeast region of the United States.

Efficacy of different analgesic strategies combined with conventional physiotherapy program for treating chronic shoulder pain: a systematic review and network meta-analysis

BACKGROUND

This study aims to investigate the efficacy of five analgesic strategies combined with conventional physiotherapy program (CPT) in managing chronic shoulder pain.

METHODS

Two authors independently screened studies, extracted data using a pre-formatted chart, and assessed bias using the Cochrane Risk of Bias tool. A network meta-analysis was performed by the Stata 17.0 and R 4.3.2 software.

RESULTS

A total of 14 studies with 862 subjects were identified. These analgesic strategies included extracorporeal shock wave therapy (ESWT), suprascapular nerve block (SSNB), corticosteroid injection (CSI), hyaluronic acid injection (HAI), and kinesio taping (KT). ESWT plus CPT was the most efficient intervention in alleviating pain intensity and improving physical function. SSNB plus CPT was the optimal intervention in improving shoulder mobility. Compared to CPT alone, CSI + CPT only significantly improved the SPADI total score, but showed no difference in pain intensity or shoulder mobility. HAI + CPT showed no significant difference in improving pain intensity, physical function, or shoulder mobility compared to CPT alone. Adding KT to CPT did not yield additional benefits in improving shoulder mobility.

CONCLUSION

Overall, in managing chronic shoulder pain, ESWT + CPT was the most effective intervention for reducing pain intensity and improving physical function. SSNB + CPT was optimal for enhancing shoulder mobility. Future rigorous clinical trials with larger sample sizes and higher methodological rigor are strongly required to confirm the current results.

Vestibular stimulation for promoting development and preventing morbidity in preterm infants

OBJECTIVES

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of vestibular stimulation compared to standard care or non-vestibular stimulation for physical and neurological development in preterm infants. To assess whether the effects of vestibular stimulation differ according to gestational age at birth; the type, frequency, and duration of the intervention; and settings, such as the country where the study is conducted.

Entrustable professional activities, emergency medicine and medical education: a systematic review

INTRODUCTION

Entrustable professional activities (EPAs) are one way to assess competencies, and are designed to bridge the gap between theoretical competencies and real world clinical practice.

AIMS

This was a systematic review which aims to answer the question: "Which EPAs related to Emergency Medicine are described for medical schools?".

METHODS

We included original qualitative, interventional and observational studies (cross-sectional, case-control, and cohort studies) that described EPAs relevant to Emergency Medicine for Medical School. The search strategy was created using a combination of keywords and standardized index terms related to EPAs and Emergency Medicine.

RESULTS

The search strategy identified 991 citations. After screening the titles and abstracts, we identified 85 potentially relevant studies. After the full-text review, a total of 11 reports met the criteria for inclusion.

CONCLUSION

Recognizing a patient requiring urgent or emergent care and initiating evaluation and management is the most common EPA related to Emergency Medicine described at Medical Schools. Use of EPAs is associated with increased student satisfaction and improved competences. However, there is a lack of undergraduate EM specific EPAs being systematically developed and published, and this should be an area to be explored in future studies.

Acupuncture for migraine: A systematic review and meta-regression of randomized controlled trials

OBJECTIVES

This meta-analysis aimed to explore the relationship between the dose of acupuncture sessions, acupuncture frequency, and acupuncture duration and its effects on migraine.

METHODS

Eight databases were searched for randomized controlled trials (RCTs) evaluating the efficacy of penetrating manual acupuncture for migraine published in English and Chinese from inception to June 20, 2024. The robust-error meta-regression (REMR) approach and non-linear meta-regression with restricted cubic spline (RCS) were used to investigate the dose-response association between acupuncture sessions, acupuncture frequency, and acupuncture duration and the frequency of migraine attacks. The potential nonlinear relationships was tested by restricting the regression coefficient to zero and a P value＜0.1. The statistical analysis was conducted using Stata 17.0. The risk of bias was independently assessed by two reviewers using the Cochrane tool. The reporting quality for acupuncture procedures was evaluated by STRICTA criteria.

RESULTS

Thirty-two RCTs involving 1562 participants were included, and the results showed a J-shaped dose-response association between acupuncture sessions, acupuncture frequency, and acupuncture duration and migraine attack frequency. After 16 acupuncture sessions, the change in the frequency of migraine attacks was 3.95 (95%CI: 3.13 to 4.77). Three sessions of acupuncture a week resulted in a significant decrease in the frequency of migraine attacks, reaching 4.04 (95% CI: 2.49 to 5.58). After two months of acupuncture, the frequency of migraine attacks decreased significantly, showing a difference of 4.05 (95% CI: 3.61 to 4.49). Subsequently, the improvement trend gradually flattened, yielding diminishing benefits to patients. The risk of bias showed that seven studies were rated as "low risk", two were rated as "high risk", and the others were rated as "unclear risk". The reporting quality of RCTs of acupuncture for migraine remain suboptimal.

CONCLUSIONS

A non-linear dose-response relationship was found between acupuncture sessions, acupuncture frequency, and acupuncture duration and migraine attack frequency. The results of our study recommend 16 sessions of acupuncture with a frequency of 3 sessions/week and a treatment duration of 1.5 to 2 months.

The Effect of Chia Seed on Blood Pressure, Body Composition, and Glycemic Control: A GRADE-Assessed Systematic Review and Dose-Response Meta-Analysis of Randomized Controlled Trials

CONTEXT

Numerous studies have demonstrated the positive effects on metabolic factors of consuming chia seeds. However, the results of clinical trials have been inconsistent.

OBJECTIVE

The aim of this study was to conduct a systematic review and meta-analysis of available randomized controlled trials to explore the effects of chia seed consumption on body weight (BW), body composition, blood pressure, and glycemic control.

DATA SOURCES

A comprehensive search was conducted on the Scopus, PubMed, Medline via Ovid, ISI Web of Science, and Scholar Google databases up to August 2023.

DATA EXTRACTION

The outcomes of interest included systolic blood pressure (SBP), diastolic blood pressure (DBP), BW, body mass index (BMI), body fat percentage, waist circumference (WC), fasting blood glucose (FBG), and hemoglobin A1c (HbA1c).

DATA ANALYSIS

Weighted mean difference (WMD) and 95% CIs were used to determine the effect size.

RESULTS

A total of 8 eligible studies were included in the analysis. The findings revealed a significant reduction in SBP (WMD: -7.19 mmHg; 95% CI, -10.63 to -3.73; P < .001) and DBP (WMD: -6.04 mmHg, 95% CI, -9.58 to -2.49; P = .001). However, no significant effects were observed on BW, body fat percentage, WC, BMI, FBG, and HbA1c. Subgroup analysis indicated that the effect of chia seed on SBP was significant in participants with a baseline SBP of less than 140 mmHg, but the effect was not dependent on the administered dose.

CONCLUSION

Chia seed consumption has positive effects on SBP and DBP but does not significantly impact BW, body composition, or glycemic parameters. However, the limited amount of data from included studies should be considered as a limitation while interpreting these findings.

Effect of Unna's boot on venous ulcer healing: a systematic review and meta-analysis

OBJECTIVE

To analyze the effect of Unna's Boot on the healing of venous ulcers compared to other therapies.

METHODS

Systematic Review carried out in the databases Scopus, Embase, Cochrane Library, Web of Science, PubMed, Cumulative Index of Nursing and Allied Health Literature, Latin American and Caribbean Literature in Health Sciences, and grey literature. Population - adult patients with venous ulcers; Intervention- Unna's Boot (UB); Control - other compression therapies (CT); Outcome- healing; Designs- randomized clinical trial, cohort study, and case control, published from 2001 to 2024. The effect of the intervention, risk of bias, and quality of evidence were evaluated. Registered with PROSPERO (CRD42021290077).

RESULTS

A total of 39 studies were included, with 5.151 patients. The majority (71.8%) were randomized controlled trials (RCT). UB was used as intervention/control in eight studies. When comparing CTs, only 1 study with UB showed a superior effect (p < .001) in healing, compared with high compression elastic bandage. In the quality of evidence analysis, 27 studies were assessed as having a high risk of bias.

CONCLUSION

No superiority of UB was found in the healing of venous ulcers when compared to other CTs.

Effectiveness and safety of continuous subcutaneous hydrocortisone infusion in managing adrenocortical insufficiency in adult patients: a systematic review

Oral hormone replacement therapy has been and continues to be the cornerstone of adrenocortical insufficiency management. However, the introduction of continuous subcutaneous hydrocortisone infusion (CSHI) shows great potential for advancing the management of adrenocortical insufficiency. It resembles the circadian rhythm of physiological cortisol secretion and was shown to have a promising outcome in terms of quality of life (QOL) and clinical outcomes in the literature. We conducted a systematic search strategy including MEDLINE, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and the online trials registers at ClinicalTrials.gov without geographic restrictions. Research investigations where self-reported quality of life (QOL) was assessed as a variable in adult individuals with confirmed adrenal disease, treated by CSHI, and results were presented in English. All articles included were published between 2014 and 2023, even though we had no timeframe limitations in our inclusion criteria. A total of six studies were included, with 63 subjects enrolled, and the average age was 40 years, a study showed a significant reduction in the average total daily dose of HC from 47.5 mg to 31.4 mg on CSHI, while other two studies estimated a reduction in the hospitalization rate due to adrenal crisis from 2.6 to 1.3 admissions per year on CSHI. Most of the studies on subjective well-being and quality of life have shown significant improvement. Overall, CSHI shows great potential as a treatment method for Adrenal insufficiency. It improves the quality of life and lowers hospitalization rates, resulting in increased patient satisfaction and acceptance. Additional comprehensive research is necessary to strengthen these discoveries, gain a deeper understanding of the effectiveness and safety of this treatment approach, and provide guidance for medical practitioners.

Systemic steroids and bronchopulmonary dysplasia: a systematic review and meta-analysis

IMPORTANCE

It is unclear if systemic steroids decrease the risk of Bronchopulmonary Dysplasia (BPD) while increasing the risk of neurodevelopmental impairment (NDI).

OBJECTIVE

Conduct a systematic review of randomized controlled trials of systemic steroids to evaluate the risk of BPD, mortality, and NDI in premature infants ≤30 weeks.

DATA SOURCES

MEDLINE, EBSCOhost, Web of Science, Cochrane Library, Embase, and CINAHL.

STUDY SELECTION

Randomized clinical trials of Dexamethasone (DEX) or Hydrocortisone (HC) to prevent BPD in premature infants ≤ 30 weeks.

DATA EXTRACTION AND SYNTHESIS

Data were extracted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Random-effects meta-analyses and multivariable meta-regression were conducted.

MAIN OUTCOMES AND MEASURES

Primary outcomes were BPD, mortality, and NDI. Secondary outcomes were hypertension, hyperglycemia, sepsis, intestinal perforation, necrotizing enterocolitis (NEC), and retinopathy of prematurity (ROP). The a priori hypothesis was that steroids would reduce the risk of BPD without increasing NDI.

RESULTS

There were 6377 preterm infants in the 44 (32 DEX, 13 HC) selected studies. DEX significantly reduced the risk of BPD, RR = 0.66, (95% CI, 0.56-0.78). The most effective DEX regimen was medium cumulative dose (2 to 3 mg/kg), RR = 0.43 (95% CI, 0.29-0.65); day of initiation <8 days: RR = 0.68, (95% CI, 0.59-0.79); and treatment for ≥14 days: RR = 0.67 (95% CI, 0.55-0.80). HC did not significantly decrease the risk of BPD, RR = 0.98, (95% CI, 0.87-1.10). Neither DEX, (RR = 0.92, 95% CI, 0.78-1.09) nor HC (RR = 0.83, 95% CI, 0.68-1.01) decrease the risk of mortality. The risk of CP was not increased by either DEX (RR = 1.09, 95% CI, 0.55-2.17) or HC (RR = 1.18, 95% CI, 0.75-1.87). There were no significant differences between steroids and placebo for MDI/PDI scores. Multivariable meta-regression models showed that DEX significantly reduced the risk of BPD without increased risk of CP. DEX increased the risk of hypertension and hyperglycemia. Studies showed high heterogeneity, differing treatment regimen, missing data and different rates of follow-up.

CONCLUSION AND RELEVANCE

DEX, but not HC, significantly decreased the risk of BPD. Neither steroid showed an increased risk of NDI or mortality.

School-Based Occupational Therapists' Roles Supporting Transitions Into and Throughout Kindergarten to Grade 12: A Scoping Review

IMPORTANCE

Large educational transitions occur when students enter and exit school or move between grades or divisions within the kindergarten to Grade 12 (K-12) school system. For students with disabilities, the quality of large educational transitions affects academic and postschool outcomes, which is germane to school-based occupational therapists.

OBJECTIVE

To explore the school-based occupational therapy literature to describe the roles of occupational therapists in supporting large educational transitions and to identify relevant terminology.

DATA SOURCES

We searched six databases (CINAHL, EMCare, Embase, ERIC, MEDLINE, and PsycINFO) for peer-reviewed publications in English with no date limitations.

STUDY SELECTION AND DATA COLLECTION

We included articles focused on children and youth with disabilities and school-based occupational therapy services supporting large transitions within K to 12 education. Using directed content analysis, we reported on publication characteristics, occupational therapy roles, and terminology.

FINDINGS

We included 46 publications spanning 37 yr that addressed transitions into school (n = 3), within K to 12 grades or divisions (n = 10), or to exit secondary education (n = 33). Occupational therapists assumed many roles in supporting large transitions, some much more frequently than others; 125 transition terms were used across included articles with few terms explicitly defined.

CONCLUSIONS AND RELEVANCE

School-based occupational therapists' involvement in educational transitions is extensive, with potential for expansion. Consistency in terminology would support future research and practice. Plain-Language Summary: A large educational transition occurs when students move between a school, grade, or division as part of their K to 12 education. For students with disabilities, the quality of a large educational transition affects their academic and postschool outcomes. This review provides an understanding of how school-based occupational therapists support educational transitions for youth with disabilities. The review found that occupational therapists took on many roles, with the potential for expanding their roles. The review also identified 125 transition terms that were used across the literature review and found that few terms were explicitly defined. Consistency in terminology would support future research and expanded occupational therapy practice in this area.

Pyodermatitis-pyostomatitis vegetans: a case report and systematic review focusing on oral involvement

BACKGROUND

Pyodermatitis-pyostomatitis vegetans (PPV) is a rare mucocutaneous disease characterized by multiple pustules and it is considered a marker for inflammatory bowel disease (IBD). The oral manifestations of this condition are referred to as pyostomatitis vegetans (PSV).

PURPOSE

To investigate which features could help in establishing the diagnosis of PSV, with or without cutaneous lesions, based on information retrieved from all cases of PSV described in the literature. A case of PV from the authors was also included in the analysis.

METHODS

An electronic search was undertaken, last updated in August 2022. Inclusion criteria included publications reporting cases of PSV, with the diagnosis confirmed by the pathological examination of oral or skin lesions, and presence of IBD.

RESULTS/CONCLUSIONS

Sixty-two publications with 77 cases of PSV and an associated IBD were included. Features that are helpful in establishing the diagnosis of PSV are snail track appearance of oral lesions, an associated IBD (which is not always symptomatic), evidence of intraepithelial clefting on microscopic examination of oral lesions, and peripheral blood eosinophilia. A gold standard for the management of PSV does not exist and high-level evidence is limited. There is no established therapeutic protocol for PSV and management primarily consists of topical and/or systemic corticosteroids, antirheumatic drugs (sulfasalazine, mesalazine), monoclonal antibody (infliximab, adalimumab) immunosuppressives (azathioprine, methotrexate), antibiotics (dapsone), or a combination of these. The risk of recurrence of oral lesions is considerable when the medication dose is decreased or fully interrupted.

Effects of mass casualty incidents on anxiety, depression, and post-traumatic stress disorder among doctors and nurses: a systematic review

OBJECTIVES

Doctors and nurses suffer different mental health conditions following traumatic incidents. We systematically synthesized existing evidence on the prevalence of anxiety, depression, and post-traumatic stress disorder (PTSD) and their associated risk factors among doctors and nurses following mass casualty incidents (MCIs).

STUDY DESIGN

Systematic review.

METHODS

Seven databases were searched (2010-2022) with peer-reviewed articles in English using the predefined keywords. Two reviewers screened the titles, abstracts, and full texts using the eligibility criteria and extracted data independently. We used the National Institutes of Health Quality Assessment Tools (NIH-QAT) and the Critical Appraisal Skills Programme checklist (CASP) to measure the quality appraisal of the included studies.

RESULTS

A total of 5170 articles were retrieved, and 2512 articles were assessed by title and abstract (53 were eligible for full-text review). Finally, we included 19 studies. Most were assessed as of fair quality with a considerable risk of bias. PTSD was the highest-reported mental health condition. Nurses reported higher mental conditions, particularly PTSD. Two sets of risk factors (personal and workplace) are associated with anxiety, depression, and PTSD were found.

CONCLUSIONS

MCIs have a significant impact on the mental health outcomes of emergency health workers. Preventive measures should be designed considering the high-risk group, personal, and organizational risk factors of mental health outcomes.

Predicting Recovery After Concussion in Pediatric Patients: A Meta-Analysis

CONTEXT

Prognostic prediction models (PPMs) can help clinicians predict outcomes.

OBJECTIVE

To critically examine peer-reviewed PPMs predicting delayed recovery among pediatric patients with concussion.

DATA SOURCES

Ovid Medline, Embase, Ovid PsycInfo, Web of Science Core Collection, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Google Scholar.

STUDY SELECTION

The study had to report a PPM for pediatric patients to be used within 28 days of injury to estimate risk of delayed recovery at 28 days to 1 year postinjury. Studies had to have at least 30 participants.

DATA EXTRACTION

The Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modeling Studies checklist was completed.

RESULTS

Six studies of 13 PPMs were included. These studies primarily reflected male patients in late childhood or early adolescence presenting to an emergency department meeting the Concussion in Sport Group concussion criteria. No study authors used the same outcome definition nor evaluated the clinical utility of a model. All studies demonstrated high risk of bias. Quality of evidence was best for the Predicting and Preventing Postconcussive Problems in Pediatrics (5P) clinical risk score.

LIMITATIONS

No formal PPM Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) process exists.

CONCLUSIONS

The 5P clinical risk score may be considered for clinical use. Rigorous external validations, particularly in other settings, are needed. The remaining PPMs require external validation. Lack of consensus regarding delayed recovery criteria limits these PPMs.

Root resorptions induced by genetic disorders: A systematic review

OBJECTIVES

Root resorption in permanent teeth is a common pathological process that often follows dental trauma or orthodontic treatment. More rarely, root resorption is a feature of genetic disorders and can help with diagnosis. Thus, the present review aims to determine which genetic disorders could induce pathological root resorptions and thus which mutated genes could be associated with them.

METHODS

We conducted a systematic review following the PRISMA guidelines. Articles describing root resorptions in patients with genetic disorders were included from PubMed, Embase, Web of Science, and Google Scholar. We synthesized the genetic disorder, the type, severity, and extent of the resorptions, as well as the other systemic and oral symptoms and histological features.

RESULTS

The synthetic analysis included 25 studies among 937 identified records. We analyzed 21 case reports, three case series, and one cohort study. Overall, we highlighted 14 different pathologies with described root resorptions. Depending on the pathology, the sites of resorption, their extent, and their severity showed differences.

CONCLUSION

With 14 genetic pathologies suspected to induce root resorptions, our findings are significant and enrich a previous classification. Among them, three metabolic disorders, three calcium-phosphorus metabolism disorders, and osteolysis disorders were identified.

Association between physical activity and risk of gastroesophageal reflux disease: A systematic review and meta-analysis

BACKGROUND

Lifestyle plays an important role in preventing and managing gastroesophageal reflux disease (GERD). In response to the conflicting results in previous studies, we performed a systematic review and meta-analysis to investigate this association.

METHODS

Relevant studies published until January 2023 were retrieved from 6 databases, and the prevalence of symptomatic gastroesophageal reflux (GER) or GERD was determined from the original studies. A random effects model was employed to meta-analyze the association by computing the pooled relative risk (RR) with 95% confidence intervals (95%CIs). Furthermore, subgroup and dose-response analyses were performed to explore subgroup differences and the association between cumulative physical activity (PA) time and GERD.

RESULTS

This meta-analysis included 33 studies comprising 242,850 participants. A significant negative association was observed between PA and the prevalence of symptomatic GER (RR = 0.74, 95%CI: 0.66-0.83; p < 0.01) or GERD (RR = 0.80, 95%CI: 0.76-0.84; p < 0.01), suggesting that engaging in PA might confer a protective benefit against GERD. Subgroup analyses consistently indicated the presence of this association across nearly all subgroups, particularly among the older individuals (RR<40 years:RR≥40 years = 0.85:0.69, p < 0.01) and smokers (RRsmoker:RRnon-smoker = 0.67:0.82, p = 0.03). Furthermore, a dose-response analysis revealed that individuals who engaged in 150 min of PA per week had a 72.09% lower risk of developing GERD.

CONCLUSION

Maintaining high levels of PA decreased the risk of GERD, particularly among older adults and smokers. Meeting the recommended PA level of 150 min per week may significantly decrease the prevalence of GERD.

Examining the use of alternative light sources in medico-legal assessments of blunt-force trauma: a systematic review

The ability to analyze blunt-force trauma is crucial for deciphering valuable clues concerning mechanisms of injury and as evidence for medico-legal investigations. The use of alternate light sources (ALS) has been studied over the past decade, and is proposed to outperform conventional white light (CWL) during bruise assessments. In response to the growing interest of the technology worldwide, a systematic review of the literature was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) to address the ability of ALS to detect and visualize bruising. From an initial 4055 records identified, ten studies met the eligibly criteria and were selected for this review. Evaluation also included a novel framework, referred to as SPICOT, to further systematically assess both scientific evidence and risk of bias in forensic literature. Analysis reveals that narrowband wavelengths within in the infrared or ultraviolet spectral ranges do not significantly outperform CWL in visualizing or detecting bruising. However, wavelengths within the visible spectrum, particularly 415 nm combined with longpass or bandpass yellow filters, are more effective. However, the majority of selected studies only address the sensitivity of ALS, and therefore, results may only be considered valid when the location of a bruise is known. Further investigation is required to understand the specificity of ALS, in particular how the use of topical cosmetic products, previous wounds/scar-tissue, tattoos, moles and freckles may affect detection. The ethical concern regarding the interpretation of enhanced visualized trauma should also be considered in prospect discussions prior to implementing ALS into routine practice. Nevertheless, this review finds that narrowband ALS within the visible spectrum demonstrates potential for improved injury documentation, outperforming CWL in the detection and visualization of bruising.

A critical and systematic literature review of epistemic justice applied to healthcare: recommendations for a patient partnership approach

Invalidation from healthcare practitioners is an experience shared by many patients, especially those marginalized or living with contested conditions (e.g., chronic pain, fibromyalgia, etc.). Invalidation can include not taking someone's testimony seriously, imposing one's thoughts, discrediting someone's emotions, or not perceiving someone's testimony as equal and competent. Epistemic injustices, that is, the disqualification of a person as a knower, are a form of invalidation. Epistemic injustices have been used as a theoretical framework to understand invalidation that occurs in the patient-healthcare provider relationship. However, to date, the different recommendations to achieve epistemic justice have not been listed, analyzed, nor compared yet. This paper aims at better understanding the state of the literature and to critically review possible avenues to achieve epistemic justice in healthcare. A systematic and critical review of the existing literature on epistemic justice was conducted. The search in four databases identified 629 articles, from which 35 were included in the review. Strategies to promote epistemic justice that can be applied to healthcare are mapped in the literature and sorted in six different approaches to epistemic justice, including virtuous, structural, narrative, cognitive, and partnership approaches, as well as resistance strategies. These strategies are critically appraised. A patient partnership approach based on the Montreal Model, implemented at all levels of healthcare systems, seems promising to promote epistemic justice in healthcare.

Contextual factors associated with subjective effects of cannabis: A systematic review and meta-analysis

BACKGROUND

Cannabis is consumed in various social and environmental settings, and such contexts may be important predictors of subjective effects. The aim of this systematic review and meta-analysis was to examine the relationship between contextual factors and subjective effects of cannabis.

METHODS

A PRISMA-guided search of MEDLINE, Embase, PsycINFO, Global Health, and Google Scholar yielded 29 studies.

RESULTS

Study type (Ecological Momentary Assessment or Experimental) was a significant predictor of intoxication effects, and experimental studies had a greater pooled effect size (z =.296,95 % CI [.132,.478], p=.004) than Ecological Momentary Assessment (EMA) studies (z =.071,95 % CI [.011,.130], p =.02). Contextual conditions (environment, social group, expectancy, time of day, day of week) were not significant predictors of cannabis effects.

CONCLUSION

Findings did not point to a significant association between contextual conditions and subjective effects. However, as current literature is methodologically weak, it may be premature to conclude that subjective effects are not shaped by contextual factors. In view of policy and therapeutic implications, replications and study refinements are recommended.

Management of impacted fetal head at cesarean birth: A systematic review and meta-analysis

INTRODUCTION

Despite increasing incidence of impacted fetal head at cesarean birth and associated injury, it is unclear which techniques are most effective for prevention and management. A high quality evidence review in accordance with international reporting standards is currently lacking. To address this gap, we aimed to identify, assess, and synthesize studies comparing techniques to prevent or manage impacted fetal head at cesarean birth prior to or at full cervical dilatation.

MATERIAL AND METHODS

We searched MEDLINE, Emcare, Embase and Cochrane databases up to 1 January 2023 (PROSPERO: CRD420212750016). Included were randomized controlled trials (any size) and non-randomized comparative studies (n ≥ 30 in each arm) comparing techniques or adjunctive measures to prevent or manage impacted fetal head at cesarean birth. Following screening and data extraction, we assessed risk of bias for individual studies using RoB2 and ROBINS-I, and certainty of evidence using GRADE. We synthesized data using meta-analysis where appropriate, including sensitivity analyses excluding data published in potential predatory journals or at risk of retraction.

RESULTS

We identified 24 eligible studies (11 randomized and 13 non-randomized) including 3558 women, that compared vaginal disimpaction, reverse breech extraction, the Patwardhan method and/or the Fetal Pillow®. GRADE certainty of evidence was low or very low for all 96 outcomes across seven reported comparisons. Pooled analysis mostly showed no or equivocal differences in outcomes across comparisons of techniques. Although some maternal outcomes suggested differences between techniques (eg risk ratio of 3.41 [95% CI: 2.50-4.66] for uterine incision extension with vaginal disimpaction vs. reverse breech extraction), these were based on unreliable pooled estimates given very low GRADE certainty and, in some cases, additional risk of bias introduced by data published in potential predatory journals or at risk of retraction.

CONCLUSIONS

The current weaknesses in the evidence base mean that no firm recommendations can be made about the superiority of any one impacted fetal head technique over another, indicating that high quality training is needed across the range of techniques. Future studies to improve the evidence base are urgently required, using a standard definition of impacted fetal head, agreed maternal and neonatal outcome sets for impacted fetal head, and internationally recommended reporting standards.

Midregional-proAdrenomedullin as a prognostic tool in sepsis and septic shock: A systematic review and meta-analysis

BACKGROUND

Midregional-proAdrenomedullin (MR-proADM) has been recently proposed as a tool in patients with sepsis and septic shock. Our aim was to evaluate the prognostic role of MR-proADM in hospitalized patients with sepsis and septic shock.

METHODS

PRISMA guideline was followed. MEDLINE and EMBASE were searched up to June 2023. Primary outcome was mean difference in MR-proADM among survivors and nonsurvivors, secondary outcome mean difference in MR-proADM according to infection severity and type. Risk of bias was evaluated using Newcastle-Ottawa scale for observational studies and Cochrane tool for randomized trials. Pooled mean differences (MD) with corresponding 95% confidence intervals (CIs) were calculated in a random-effects model.

RESULTS

Twenty-four studies included 6730 adult patients (1208 nonsurvivors and 5522 survivors) and three studies included 195 paediatric patients (30 nonsurvivors and 165 survivors). A total of 10, 4 and 13 studies included, respectively, patients with sepsis (3602 patients), septic shock (386 patients) and a mixed population (2937 patients). Twenty-one studies included patients with different source of infection, three with pneumonia and one with a catheter-related infection. Most studies (n = 12) had a follow-up of 28 days. In adult cohort, pooled mean difference between nonsurvivors and survivors of MR-proADM was 2.55 mmol/L (95% CI: 1.95-3.15) with higher values in patients with septic shock (4.25 mmol/L; 95% CI, 2.23-6.26 mmol/L) than in patients with sepsis (1.77 mmol/L; 95% CI: 1.11-2.44 mmol/L). In paediatric cohort, pooled mean difference was 3.11 mmol/L (95% CI: -0.02-6.24 mmol/L).

CONCLUSIONS

Higher values of MR-proADM are detectable in nonsurvivors adult and paediatric-hospitalized patients with sepsis or septic shock.

Prediabetes and the treatment outcome of tuberculosis: A meta-analysis

OBJECTIVES

Diabetes has been related to higher risk and poor prognosis of patients with tuberculosis, while the influence of prediabetes on the treatment outcome of patients with tuberculosis remains not determined. A meta-analysis was performed to evaluate the influence of prediabetes on treatment outcome of patients with tuberculosis.

METHODS

Relevant cohort studies were acquired through a search of Medline, Embase, and Web of Science databases. To minimise the influence of between-study heterogeneity, a randomised-effects model was used to pool the results.

RESULTS

Eight prospective cohort studies including 3001 patients with tuberculosis were available for the meta-analysis. Among them, 752 (25.1%) were with prediabetes at baseline, and the patients were followed for a mean duration of 17.7 months. It was shown that compared to patients with normoglycemia, those with prediabetes were associated with a higher incidence of unfavourable treatment outcome (risk ratio [RR]: 1.41, 95% confidence interval [CI]: 1.02 to 1.96, p = 0.04; I2 = 56%). Subgroup analysis did not support that difference in study country (Asian or non-Asian), diagnosis (pulmonary tuberculosis only or also with extrapulmonary tuberculosis), mean age, follow-up duration, or study quality score had significant influence on the results (p for subgroup difference all >0.05). However, prediabetes at baseline was not associated with an increased risk of all-cause mortality during follow-up (RR: 1.59, 95% CI: 0.75 to 3.38, p = 0.23; I2 = 54%).

CONCLUSIONS

Patients with tuberculosis and prediabetes may have a higher risk of unfavourable treatment outcome compared to patients with normoglycemia.

The OHStat guidelines for reporting observational studies and clinical trials in oral health research: manuscript checklist

Adequate and transparent reporting is necessary for critically appraising published research, yet ample evidence suggests that the design, conduct, analysis, interpretation, and reporting of oral health research could be greatly improved. Accordingly, the Task Force on Design and Analysis in Oral Health Research, statisticians and trialists from academia and industry, identified the minimum information needed to report and evaluate observational studies and clinical trials in oral health: the OHStat guidelines. Drafts were circulated to the editors of 85 oral health journals and to Task Force members and sponsors and discussed at a December 2020 workshop attended by 49 researchers. The guidelines were subsequently revised by the Task Force writing group. The guidelines draw heavily from the Consolidated Standards for Reporting Trials (CONSORT), Strengthening the Reporting of Observational Studies in Epidemiology, and CONSORT harms guidelines, and incorporate the SAMPL guidelines for reporting statistics, the CLIP principles for documenting images, and the GRADE indicating the quality of evidence. The guidelines also recommend reporting estimates in clinically meaningful units using confidence intervals, rather than relying on P values. In addition, OHStat introduces seven new guidelines that concern the text itself, such as checking the congruence between abstract and text, structuring the discussion, and listing conclusions to make them more specific. OHStat does not replace other reporting guidelines; it incorporates those most relevant to dental research into a single document. Manuscripts using the OHStat guidelines will provide more information specific to oral health research.

Non-pharmacological interventions to reduce thirst in patients with heart failure or hemodialysis: A systematic review and meta-analysis

BACKGROUND

Thirst is a frequent and burdening symptom in many patients, especially in patients with chronic heart failure (CHF) and/or receiving hemodialysis (HD). As drug therapies are not feasible, non-pharmacological strategies are needed to reduce thirst and thirst-related burden.

OBJECTIVES

To identify non-pharmacological interventions aiming to reduce thirst in patients with CHF and/ or HD, to describe intervention components, and to evaluate the effectiveness of these interventions.

METHODS

In February 2024, we completed a systematic search in MEDLINE via PubMed, Livivo, CINAHL, Cochrane Library and Web of Science. Two reviewers independently screened titles, abstracts, and full texts, performed critical appraisal and data extraction. We checked risk of bias with the checklists of the Joanna Briggs Institute and the Cochrane Risk of Bias tool and calculated meta-analyses for sufficiently homogeneous studies using fixed-effects models.

RESULTS

We included 15 intervention studies applying non-pharmacological interventions including chewing gum (n = 8), low-sodium diet (n = 2), acupressure (n = 1), frozen strawberries (n = 1), fluid timetables (n = 1), ice cubes and mouthwash (n = 1), and a psychological intervention (n = 1). Sample sizes varied between 11 and 88 participants. Eleven intervention studies showed a reduction of thirst as intervention effect. Meta-analyses for chewing gum showed no significant effect on thirst using a visual analogue scale (IV: -2,32 [-10.37,5.73]; p = 0.57) or the dialysis thirst inventory (IV: -0.26 [- 1.83, 1.30]; p = 0.74). Quality of studies was moderate to low.

CONCLUSION

Results indicate that various non-pharmacological interventions could be helpful to reduce thirst in patients with CHF or HD, but important uncertainty remains.

Comparative efficacy of endoscopic ultrasound-guided biliary drainage versus endoscopic retrograde cholangiopancreatography as first-line palliation in malignant distal biliary obstruction: a systematic review and meta-analysis

Background

Malignant distal biliary obstruction (MDBO) is a challenging clinical condition commonly managed with endoscopic retrograde cholangiopancreatography (ERCP). However, endoscopic ultrasound-guided biliary drainage (EUS-BD) has emerged as an alternative, especially in complex cases where ERCP fails or is deemed risky. This study aimed to compare the efficacy, safety and cost-effectiveness of EUS-BD vs. ERCP in the palliation of MDBO.

Methods

We conducted a systematic review and meta-analysis, following PRISMA guidelines. Three databases were searched up to December 2023, including MEDLINE/PubMed, OVID and the Cochrane Central Register of Controlled Trials, for studies comparing EUS-BD with ERCP. Primary outcomes were technical and clinical success rates, while secondary outcomes included procedural times, hospital stay duration, 30-day mortality, reintervention rates, and adverse events such as pancreatitis.

Results

Seven studies involving 1245 patients met the inclusion criteria. The meta-analysis revealed that EUS-BD had a technical success rate of 92%, compared to 85% for ERCP. Clinical success rates were similar for both EUS-BD and ERCP, at approximately 89%. EUS-BD was associated with a significantly lower incidence of pancreatitis (2% vs. 10% for ERCP).

Conclusions

EUS-BD offers a viable and potentially superior alternative to ERCP for the primary palliation of MDBO, particularly in terms of technical success and a lower risk of pancreatitis. These findings support the adoption of EUS-BD in clinical settings equipped to perform this technique, though future research should focus on long-term outcomes and further economic analysis to solidify these recommendations.

Oral health indicators and bone mineral density disorders in older age: A systematic review

As we age, maintaining good oral health becomes increasingly crucial for performing daily tasks. Age-related physiological decline can disrupt various biological systems, causing a significant challenge for geriatric dentistry. A systematic review of the literature using six different electronic databases was conducted to investigate the relationship between oral health indicators and bone mineral density disorders in older adults. The study is registered as a priori protocol on PROSPERO (CRD42023403340). A minimum age of 60 years was the main inclusion criterion for all original research articles. Two independent researchers assessed the eligibility of 19,362 records against the inclusion criteria and found 12 articles fitting the eligibility requirements. Five different indicators of poor oral health [number of teeth, periodontal disease, general oral health (dental caries prevalence and dental treatment needs), masticatory function, and occlusal force)] were found related to three outcomes linked to bone mineral density disorders (osteoporosis, fractures, and decreased bone mineral density), regardless of the adopted assessment tools. The number of teeth was negatively associated with fractures and a decreased bone mineral density, while periodontal disease was positively associated with osteoporosis and a decreased bone mineral density. Masticatory function was associated only with osteoporosis, while general oral health was associated only with fractures and occlusal force only with bone mineral density. The oral health indicator most frequently associated with outcomes linked to bone mineral density disorders was the number of teeth. The present findings could help to assess the contribution of each oral health indicator to the development of bone mineral density disorders in older age.

FDG-PET in the diagnosis of primary progressive aphasia: a systematic review

Primary progressive aphasia (PPA) is a disease known to affect the frontal and temporal regions of the left hemisphere. PPA is often an indication of future development of dementia, specifically semantic dementia (SD) for frontotemporal dementia (FTD) and logopenic progressive aphasia (LPA) as an atypical presentation of Alzheimer's disease (AD). The purpose of this review is to clarify the value of 2-deoxy-2-[18F]fluoro-D-glucose (FDG)-positron emission tomography (PET) in the detection and diagnosis of PPA. A comprehensive review of literature was conducted using Web of Science, PubMed, and Google Scholar. The three PPA subtypes show distinct regions of hypometabolism in FDG-PET imaging with SD in the anterior temporal lobes, LPA in the left temporo-parietal junction, and nonfluent/agrammatic Variant PPA (nfvPPA) in the left inferior frontal gyrus and insula. Despite the distinct patterns, overlapping hypometabolic areas can complicate differential diagnosis, especially in patients with SD who are frequently diagnosed with AD. Integration with other diagnostic tools could refine the diagnostic process and lead to improved patient outcomes. Future research should focus on validating these findings in larger populations and exploring the therapeutic implications of early, accurate PPA diagnosis with more targeted therapeutic interventions.

Analysis and mapping of global research publications on point-of-care testing for infectious diseases

RATIONALE

This study presents the first comprehensive analysis and mapping of scientific research on point-of-care testing (POCT) in infectious diseases, filling a gap in understanding the evolving landscape of this field. The identification of research themes and global contributions offers valuable insights.

AIMS AND OBJECTIVES

This manuscript aims to analyse and map scientific research on POCT in the context of infectious diseases.

METHODS

The study employed a comprehensive search strategy using terms related to POCT and infectious diseases. The search was conducted on the Scopus database, refining results based on inclusion and exclusion criteria. The dataset of 1719 research articles was then subjected to descriptive analysis and mapping using VOSviewer.

RESULTS

The research findings indicate an exponential growth in POCT-related publications, with 46.8% published post the COVID-19 pandemic. Plos One journal led in publication frequency, and Biosensors and Bioelectronics received the highest citations per article. North America and Western Europe dominated contributions, with notable participation from China, South Africa, and India. The research landscape revealed the following research themes: detection technologies, human immunodeficiency virus (HIV)/sexually transmitted infection (STI) diagnosis, antibiotic optimisation, and schistosomiasis. Clinical trials focused on antibiotic prescribing, HIV, STIs, and specific infections. The findings suggest a shifting landscape towards POCT, emphasising the need for future planning and investment in healthcare systems. The research identifies areas for future exploration, such as the impact of POCT on antibiotic prescribing and its role in combating infectious diseases in low- and middle-income countries.

CONCLUSION

Implementation of POCT has the potential to revolutionise infectious disease management, improve patient outcomes, and reduce the global burden of diseases. Better public awareness, healthcare team management, and planning for POCT at entry points are crucial for societal benefit. Results demonstrated the evolving role of POCT in infectious disease management and prevention.

The relationship of social contacts with prisoners' mental health: a systematic review

OBJECTIVES

Prisoners' common mental disorders (CMDs) and their social contacts are a complex and significant concern. We have systematically investigated the relationship between social contacts (i.e. perceived, and objective social support, and loneliness) and prisoners' mental health.

STUDY DESIGN

This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA).

METHODS

A protocol was developed and registered in PROSPERO (CRD42023372942). A search strategy was applied across four databases (namely MEDLINE [via OVID SP], APA PsycINFO, Scopus, and Web of Science). The quality assessment entailed the critical appraisal skills program (CASP) Checklist for cohort studies. The data were presented through a narrative synthesis.

RESULTS

After screening, 32 studies that fulfilled the inclusion criteria were included in this review. Most were cross-sectional (k = 27), while five had a longitudinal design. The total number of study participants was 10,613. The majority of the studies reported negative correlations between perceived and objective social support and symptoms of common mental disorders (CMDs), specifically, depression, anxiety, and post-traumatic stress disorder (PTSD). The included studies appeared to indicate a correlation between loneliness and PTSD symptoms.

CONCLUSIONS

The lack of social support was linked to the development or exacerbation of CMDs in prisoners. Initiatives, such as reducing visitation barriers and providing access to technology for remote communication, can assist prisoners in strengthening their support systems and enhancing their opportunities for reintegration into society.

A Multimodal Approach to Measuring Listening Effort: A Systematic Review on the Effects of Auditory Task Demand on Physiological Measures and Their Relationship

OBJECTIVES

Listening effort involves the mental effort required to perceive an auditory stimulus, for example in noisy environments. Prolonged increased listening effort, for example due to impaired hearing ability, may increase risk of health complications. It is therefore important to identify valid and sensitive measures of listening effort. Physiological measures have been shown to be sensitive to auditory task demand manipulations and are considered to reflect changes in listening effort. Such measures include pupil dilation, alpha power, skin conductance level, and heart rate variability. The aim of the current systematic review was to provide an overview of studies to listening effort that used multiple physiological measures. The two main questions were: (1) what is the effect of changes in auditory task demand on simultaneously acquired physiological measures from various modalities? and (2) what is the relationship between the responses in these physiological measures?

DESIGN

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, relevant articles were sought in PubMed, PsycInfo, and Web of Science and by examining the references of included articles. Search iterations with different combinations of psychophysiological measures were performed in conjunction with listening effort-related search terms. Quality was assessed using the Appraisal Tool for Cross-Sectional Studies.

RESULTS

A total of 297 articles were identified from three databases, of which 27 were included. One additional article was identified from reference lists. Of the total 28 included articles, 16 included an analysis regarding the relationship between the physiological measures. The overall quality of the included studies was reasonable.

CONCLUSIONS

The included studies showed that most of the physiological measures either show no effect to auditory task demand manipulations or a consistent effect in the expected direction. For example, pupil dilation increased, pre-ejection period decreased, and skin conductance level increased with increasing auditory task demand. Most of the relationships between the responses of these physiological measures were nonsignificant or weak. The physiological measures varied in their sensitivity to auditory task demand manipulations. One of the identified knowledge gaps was that the included studies mostly used tasks with high-performance levels, resulting in an underrepresentation of the physiological changes at lower performance levels. This makes it difficult to capture how the physiological responses behave across the full psychometric curve. Our results support the Framework for Understanding Effortful Listening and the need for a multimodal approach to listening effort. We furthermore discuss focus points for future studies.

Estimated Doses to the Heart, Lungs and Oesophagus and Risks From Typical UK Radiotherapy for Early Breast Cancer During 2015-2023

PURPOSE

Breast cancer radiotherapy can increase the risks of heart disease, lung cancer and oesophageal cancer. At present, the best dosimetric predictors of these risks are mean doses to the whole heart, lungs and oesophagus, respectively. We aimed to estimate typical doses to these organs and resulting risks from UK breast cancer radiotherapy.

METHODS

A systematic review and meta-analysis was conducted of planned or delivered mean doses to the whole heart, lungs or oesophagus from UK breast cancer radiotherapy in studies published during 2015-2023. Average mean doses were summarised for combinations of laterality and clinical targets. Heart disease and lung cancer mortality risks were then estimated using established models.

RESULTS

For whole heart, thirteen studies reported 2893 doses. Average mean doses were higher in left than in right-sided radiotherapy and increased with extent of clinical targets. For left-sided radiotherapy, average mean heart doses were: 2.0 Gy (range 1.2-8.0 Gy) breast/chest wall, 2.7 Gy (range 0.6-5.6 Gy) breast/chest wall with either axilla or supraclavicular nodes and 2.9 Gy (range 1.3-4.7 Gy) breast/chest wall with nodes including internal mammary. For right-sided radiotherapy, average mean heart doses were: 1.0 Gy (range 0.3-1.0 Gy) breast/chest wall and 1.2 Gy (range 1.0-1.4 Gy) breast/chest wall with either axilla or supraclavicular nodes. There were no whole heart dose estimates from right internal mammary radiotherapy. For whole lung, six studies reported 2230 doses. Average mean lung doses increased with extent of targets irradiated: 2.6 Gy (range 1.4-3.0 Gy) breast/chest wall, 3.0 Gy (range 0.9-5.1 Gy) breast/chest wall with either axilla or supraclavicular nodes and 7.1 Gy (range 6.7-10.0 Gy) breast/chest wall with nodes including internal mammary. For whole oesophagus, two studies reported 76 doses. Average mean oesophagus doses increased with extent of targets irradiated: 1.4 Gy (range 1.0-2.0 Gy) breast/chest wall with either axilla or supraclavicular nodes and 5.8 Gy (range 1.9-10.0 Gy) breast/chest wall with nodes including internal mammary.

CONCLUSIONS

The typical doses to these organs may be combined with dose-response relationships to estimate radiation risks. Estimated 30-year absolute lung cancer mortality risks from modern UK breast cancer radiotherapy for patients irradiated when aged 50 years were 2-6% for long-term continuing smokers, and <1% for non-smokers. Estimated 30-year mortality risks for heart disease were <1%.

Inter-observer and intra-observer agreement of cervical vertebral maturation staging: A systematic review and meta-analysis

INTRODUCTION

The accurate assessment of active growth is pivotal for the correction of skeletal malocclusion in growing patients. Cervical vertebral maturation (CVM) staging is easy and devoid of unnecessary radiation, but its inter- and intra-observer agreement is still debatable.

OBJECTIVE

This study aims to assess inter-observer (reliability) and intra-observer agreement (reproducibility) for CVM staging.

METHODS

A comprehensive literature search across five databases up to October 2023 was conducted. Inclusion criteria comprised observational studies that specifically reported intra-rater, inter-rater, or both agreements as their primary objectives for cervical vertebral maturation (CVM) staging. Studies with a sample size exceeding 15 participants were considered for inclusion. After duplicate study selection, data extraction, and risk-of-bias assessment, random-effects meta-analyses of kappa (k)/correlation coefficient (r) and their 95% confidence intervals (CIs) were performed, followed by meta-regressions, sensitivity analyses, and subgroup analyses.

RESULTS

Seventeen observational studies (comprising 1437 lateral cephalograms and 110 assessors) were included. The reliability (8 studies; k=0.62 [95% CI: 0.44, 0.78]) and reproducibility (9 studies; k=0.708 [95% CI: 0.59, 0.82]) were substantial. The inter-observer correlation was almost perfect (in 9 studies; r=0.86 [95% CI: 0.82, 0.89]) while intra-observer correlation was substantial (in 2 studies; r=0.75 [95% CI: 0.62, 0.84]). Tracing of lateral cephalograms significantly increased inter-observer reliability (β=0.29 [0.57, 0.0031]) but cropping and time of assessment (initial vs. follow-up) had no significant impact. The reliability (P<0.001) and reproducibility (P=0.049) of high-quality studies were superior to those observed in low-quality studies.

CONCLUSION

Assessment of the CVM staging is accurate and reproducible to a satisfactory level. The accuracy and reproducibility of CVM are higher in studies utilizing traced cephalograms and those with a low-risk of bias.

Synchronous cemento-ossifying fibromas: a systematic review

BACKGROUND

This systematic review aimed to incorporate published data regarding synchronous cemento-ossifying fibromas (COF), with an analysis of their demographic and clinicopathological characteristics.

MATERIAL AND METHODS

Case reports and case series of synchronous COF were searched in PubMed, Web of Science, Scopus, EMBASE, and LILACS according to the PRISMA (2020) statement. Also, a manual search was carried out and the grey literature was assessed. A descriptive statistical analysis was performed.

RESULTS

Nineteen studies comprising 20 cases of synchronous COF were included. The mean age at diagnosis was 35 years (±13.8), with a predominance of female patients (n=12/60%). In 13 cases (65%) the mandible and the maxilla were affected simultaneously. In two cases (10%) first-degree relatives (parents or siblings) had been previously diagnosed with COF. The diagnostic hypotheses were reported in 8 cases (40%), with florid cemento-osseous dysplasia, ameloblastic fibroodontoma, calcifying cystic odontogenic tumor, osteoma and cementoblastoma being cited in the differential diagnosis. Among the cases with details about management (n=17), eleven were treated by surgical enucleation and/or excision (64.7%). Follow-up was provided for 10 cases (50%), with a mean period of 44.7±62.19 months. Recurrence occurred in three of informed cases.

CONCLUSIONS

Synchronous manifestation of COF is rare. Female patients around the 3rd decade of life are more commonly affected. Bilateral involvement of the mandible and maxilla is the most common clinical presentation.

A systematic review of Intensive Comprehensive Aphasia Programmes - who takes part, what is measured, what are the outcomes?

PURPOSE

This study synthesizes participant and outcome data from peer-reviewed Intensive Comprehensive Aphasia Programme (ICAP) studies.

METHODS

A systematic review was conducted following PRISMA guidelines. Study eligibility criteria were specified in relation to population, intervention, comparison, outcome, and design considerations. Data were extracted according to six research questions. Narrative synthesis was used.

RESULTS

Twenty-one studies were included covering 13 ICAPs (N = 485, aged 18-86 years, between 11 and 335 months post-stroke). Twenty-seven participant selection criteria were identified. Fifty-six outcome measures spanning the WHO-ICF were used, with the majority assessing the body function domain. Only eight studies employed an experimental design with data appropriate for analysis and synthesis. Risk of bias was noted across this sub-group. Participants improved in word-finding, communication, activity/participation, and communication-related quality of life, and maintained their gains; however, except for word finding, evidence of effect came from isolated studies. Factors influencing outcomes were rarely considered. Some drop-outs, missed sessions, and fatigue were noted. Some studies reported IPD alongside group analyses.

CONCLUSIONS

ICAP selection criteria need justification and should contribute to the understanding of candidacy for this treatment model. Rationalisation of ICAP treatment content and outcome measurement is required, spanning all WHO-ICF domains. Employment of the core outcome set for aphasia would enable data synthesis and facilitate comparisons between the ICAP and other therapy models.
