Conducting multicenter randomized controlled trials (RCTs) in pediatric surgery for rare congenital anomalies presents unique challenges, including low patient recruitment, complex regulatory landscapes, and variability in care standards. This paper reflects on the experiences and lessons learned from the MUC-FIRE and STEPS-EA trials, supported by the European Reference Network for Rare Inherited and Congenital Anomalies (ERNICA), to provide guidance for future studies.A retrospective review was conducted on the design and execution of these trials, focusing on team composition, endpoint selection, patient recruitment strategies, regulatory compliance, and adaptive methodologies. Insights were derived from study protocols, monitoring reports, and the authors' experiences.Key factors contributing to trial success included multidisciplinary collaboration, leveraging existing research networks, and defining clear, measurable endpoints. Challenges such as recruitment delays, regulatory hurdles, and variations in care were mitigated through flexible protocols, proactive amendments, and stakeholder engagement. The COVID-19 pandemic amplified these difficulties, necessitating innovative strategies and extended timelines.The MUC-FIRE and STEPS-EA trials underscore the critical importance of international collaboration, adaptive strategies, and patient-centered approaches in overcoming the complexities of multicenter RCTs. Lessons from these experiences can inform the design and implementation of future trials, ultimately enhancing evidence generation and improving outcomes for children with rare congenital anomalies.

To inform an efficient development of new investigational anti-amyloid beta (anti-Aβ) monoclonal antibodies (mAbs), a modeling-and-simulation-based strategy was proposed. A general modeling framework that links drug exposures to the time course of amyloid plaque removal and amyloid-related imaging abnormalities characterized by edema and effusion (ARIA-E) was developed based on publicly available data on aducanumab, lecanemab, and donanemab. A non-linear mixed effect model with shared model parameters described the dose response data from aducanumab, lecanemab, and donanemab studies after adjusting for different potency for different antibodies, which allowed the rate of amyloid plaque removal to vary by drug. A time-to-event model was developed to describe ARIA-E incidence. The model assumes that ARIA-E incidence rate is dependent on the rate of amyloid plaque removal with a drug-dependent scaling factor linking amyloid plaque removal rate and treatment-dependent hazard. Simulations of amyloid plaque removal and ARIA-E for a hypothetical anti-Aβ mAb based on certain assumptions and scenarios provided insights into possible outcomes. Overall, the meta-analysis of published data on existing anti-Aβ mAbs could be utilized to model exposure-response relationships and the time course of amyloid plaque removal and ARIA-E incidence of new anti-Aβ mAbs and to inform the design of early clinical trials for them.

This pre-registered (#CRD42024509947) systematic review synthesized evidence on cognitive behavioral interventions (CBTs) for youths with school attendance problems (SAPs). The PsycINFO, PubMed, ERIC, and Scopus databases were searched through 1985-2024 for randomized controlled trials (RCTs), non-RCTs, and open trials (OTs) evaluating SAP-focused CBT. Data were synthesized narratively and through meta-analysis. Four RCTs and eleven OTs met eligibility criteria, including 932 youths. Meta-analyses revealed small to large uncontrolled pre- to post-intervention effects for school attendance (g = 1.02), anxiety (g = - 0.57), depression (g = - 0.66), and behavioral problems (g = - 0.40), which were maintained at follow-up. When compared to a control, CBT had a medium effect on school attendance (g = 0.44) but non-significant effects on anxiety (g = - 0.09) and depression (g = - 0.14). While the results hold promise for SAP-focused CBTs, evidence was limited by study heterogeneity, bias risks, methodological limitations, and inconsistent outcome measures, highlighting the needed for further RCTs.

The aim of this systematic review was to determine the processes and forms of participation in Otago Exercise Program (OEP) and Aquatic exercise(AE) for the prevention of falls in older adults, and to compare the effectiveness of the two exercises as interventions for the prevention of falls in older adults.

Using electronic databases such as PubMed, Web of Science, Embase, Scopus, and Google Scholar, we searched for relevant domestic and foreign papers in the last 15 years, and evaluated the methodology and quality of the report by both AMSTAR 2 and PRISMA scales to evaluate the methodology and reporting quality.

A total of 33 papers were included by searching various literatures related to the topic of this study and carefully reviewed by the researcher.

This systematic review confirms that OEP and AE effectively prevent falls in older adults by improving cognitive function, lower limb muscle strength, and balance. OEP significantly enhances muscle strength, while AE shows slight superiority in improving balance-related abilities like gait stability. These findings highlight the need for optimized training cycles in OEP and AE to maximize muscle adaptation. Both programs are safe and effective, with potential to reduce falls and enhance physical and cognitive functions. Tailored interventions, aligned with home health care guidelines and specific living environments, can improve quality of life. Future research should explore the optimal exercise modalities and intensities, and conduct longitudinal studies to assess long-term outcomes, particularly for older adults with specific health conditions.

A growing number of meta-analyses (MA) have investigated the use of spinal cord stimulation (SCS) as a treatment modality for chronic pain. The quality of these MAs has not been assessed by validated appraisal tools.

To examine the methodological characteristics and quality of MAs related to the use of SCS for chronic pain syndromes.

An online literature search was conducted in Ovid MEDLINE(R), Ovid EMBASE, Ovid Cochrane Database of Systematic Reviews, and Scopus databases (January 1, 2000 through June 30, 2023) to identify MAs that investigated changes in pain intensity, opioid consumption, and/or physical function after SCS for the treatment of chronic pain. MA quality was assessed using A Measurement Tool to Assess Systematic Reviews (AMSTAR-2) critical appraisal tool.

Twenty-five MAs were appraised in the final analysis. Three were considered "high" quality, three "low" quality, and 19 "critically low" quality, per the AMSTAR-2 criteria. There was no association between the publication year and AMSTAR-2 overall quality (β 0.043; 95% CI -0.008 to 0.095; p=0.097). There was an association between the impact factor and AMSTAR-2 overall quality (β 0.108; 95% CI 0.044 to 0.172; p=0.002), such that studies published in journals with higher impact factors were associated with higher overall quality. There was no association between the effect size and AMSTAR-2 overall quality (β -0.168; 95% CI -0.518 to 0.183; p=0.320).According to our power analysis, three studies were adequately powered (>80%) to reject the null hypothesis, while the remaining studies were underpowered (<80%).

The study demonstrates a critically low AMSTAR-2 quality for most MAs published on the use of SCS for treating chronic pain. Future MAs should improve study quality by implementing the AMSTAR-2 checklist items.

Amongst the main perspectives when evaluating the results of medical studies are statistical significance (following formal statistical testing) and clinical significance. While statistical significance shows that a factor's observed effect on the study results is unlikely (for a given alpha) to be due to chance, effect size shows that the factor's effect is substantial enough to be clinically useful. The essence of statistical significance is "negative" - that the effect of a factor under study probably did not happen by chance. In contrast, effect size and clinical significance evaluate whether a clinically "positive" effect of a factor is effective and cost-effective. Medical diagnoses and treatments should never be based on the results of a single study. Results from numerous well-designed studies performed in different circumstances are needed, focusing on the magnitude of the effects observed and their relevance to the medical matters being studied rather than on the p-values. This paper discusses statistical inference and its relevance to clinical importance of quantitative testing in clinical laboratories. To achieve this, we first pose questions focusing on fundamental statistical concepts and their relationship to clinical significance. The paper also aims to provide examples of using the methodological approaches of superiority, equivalence, non-inferiority, and inferiority studies in clinical laboratories, which can be used in evidence-based decision-making processes for laboratory professionals.

Historically, ferns have been described as underutilized by insects. However, studies have shown a diversity of insects interacting with ferns, although the evolutionary and ecological drivers of these interactions are still to be untangled. To fill these gaps, we compiled more than 100 yr of global data on insect-fern interactions from the literature comprising 374 fern and 649 insect species. With this database we assessed how fern trophic specialization, phylogenetic relationships and climate have shaped their interactions with insects. Our findings showed that interactions between ferns and insects can be explained by the phylogenetic relations among them. We observed that insect orders part of the Endopterygota clade tend to interact with similar fern species, which might be a result of the inheritance of Endopterygota ancestors probably due to phylogenetic niche conservationism. Under an ecological context, fern specialization increased with temperature, precipitation, and climatic stability. Our results show that climate might be one of the main factors explaining the spatial variation of insect-fern interactions, postulate also supported by the observed phylogenetic clustering of the studied ferns species. Our study highlights the intricate and multifaceted nature of insect-fern interactions, where evolutionary history and ecological factors converge to shape these relationships.

The outcome of Low Flow-Low Gradient (LF-LG) severe aortic stenosis (AS) patients who underwent Transcatheter Aortic Valve Replacement (TAVR) procedure is not well defined. We conducted a systematic review of the literature to compare the outcomes of TAVR in LF-LG AS patients to the more traditional high gradient (HG) aortic stenosis.

We comprehensively searched for controlled randomized and non-randomized studies from 4 online databases. We are presenting the data using risk ratios (95 % confidence intervals) and measuring heterogeneity using Higgins' I2 index.

Our analysis included 4380 patients with 3425 HG patients and 955 LF-LG patients from 6 cohort (5 retrospective and 1 prospective) studies. When compared to LFLG; TAVR was associated with significantly lower 30 days mortality in HG patients (5.1 % vs 7.4 %; relative risk [RR]: 0.55; 95 % confidence interval [CI]: 0.35 to 0.86; p < 0.01). Similar findings were also observed in 12-month cardiovascular (CV) mortality (5.5 % vs. 10.4 %; RR: 0.47; 95 % CI: 0.38 to 0.60; p < 0.01 and 12-month all-cause mortality (15.9 % vs 20.9 %; RR: 0.70; 95 % CI: 0.49 to 1.00; p < 0.05). There was no significant difference in myocardial infarction (MI) after TAVR between HG and LF-LG at 30 days (0.16 % vs. 0.95 %; p < 0.09) or 12 months (0.43 % vs. 0.95 %; p = 0.20). Similarly, there was no difference in stroke rates at 30 days (2.9 % vs. 2.86 %) or at 12 months (3.6 % vs. 3.06 %).

Patients with LF-LG severe AS who underwent TAVR had worse 1-year all-cause mortality, 30-day all-cause, and 1-year CV mortality when compared to TAVR in HG severe AS. There was no difference in MI or stroke rates. Therefore, with heart team discussion and informed patient decision regarding the risk and benefit, TAVR would still offer better outcomes in LFLG AS compared to conservative medical management.

Machine learning-based computer vision techniques using depth cameras have shown potential in physiotherapy movement assessment. However, a comprehensive understanding of their implementation, effectiveness, and limitations remains needed. Following PRISMA guidelines, we systematically reviewed studies from 2020 to 2024 across Web of Science, Scopus, PubMed, and Astrophysics Data System to explore recent advancements. From 371 initially identified publications, 18 met the inclusion criteria for detailed analysis. The analysis revealed three primary implementation scenarios: local (50%), clinical (33.4%), and remote (22.3%). Depth cameras, particularly the Kinect series (65.4%), dominated data collection methods. Data processing approaches primarily utilized RGB-D (55.6%) and skeletal data (27.8%), with algorithms split between traditional machine learning (44.4%) and deep learning (41.7%). Key challenges included limited real-world validation, insufficient dataset diversity, and algorithm generalization issues, while machine learning-based computer vision systems demonstrated effectiveness in movement assessment tasks, further research is needed to address validation in clinical settings and improve algorithm generalization. This review provides a foundation for enhancing computer vision-based assessment tools in physiotherapy practice.

A systematic review is a type of literature review that uses rigorous methods to synthesize evidence from multiple studies on a specific topic. It is widely used in academia, including medical and social science research. Social science is an academic discipline that focuses on human behaviour and society. However, consensus regarding the standards and criteria for conducting and reporting systematic reviews in social science is lacking. Previous studies have found that the quality of systematic reviews in social science varies depending on the topic, database, and country.

This study evaluates the completeness of reporting and methodological quality of intervention and non-intervention systematic reviews in social science in China. Additionally, we explore factors that may influence quality.

We searched three major Chinese electronic databases-CNKI, VIP, and Wangfang-for intervention and non-intervention reviews in social science published in Chinese journals from 1 January 2009 to 2 December 2022.

We included intervention and non-intervention reviews; however, we excluded overviews, qualitative syntheses, integrative reviews, rapid reviews, and evidence syntheses/summaries. We also excluded meta-analyses that used advanced methods (e.g., cross-sectional, cumulative, Bayesian, structural equation, or network meta-analyses) or that focused on instrument validation.

We extracted data using a coding form with publication information and study content characteristics. This study conducted pilot extraction and quality assessment with four authors and formal extraction and assessment with two groups of four authors each. PRISMA2020 and MOOSE were used to evaluate the reporting completeness of intervention and non-intervention reviews. AMSTAR-2 and DART tools were adopted to assess their methodological quality. We described the characteristics of the included reviews with frequencies and percentages. We used SPSS (version 26.0) to conduct a linear regression analysis and ANOVA to explore the factors that may influence both completeness of reporting and methodological quality.

We included 1176 systematic reviews with meta-analyses published in Chinese journals between 2009 and 2022. The top three fields of publication were psychology (417, 35.5%), education (388, 33.0%), and management science (264, 22.4%). Four hundred and thirty-two intervention reviews were included. The overall completeness of reporting in PRISMA and compliance rate of the methodological process in AMSTAT-2 were 49.9% and 45.5%, respectively. Intervention reviews published in Chinese Social Science Citation Index (CSSCI) journals had lower reporting completeness than those published in non-CSSCI journals (46.7% vs. 51.1%), similar to methodological quality (39.6% vs. 47.9%). A few reviews reported the details on registration (0.2%), rationality of study selection criteria (1.6%), sources of funding for primary studies (0.2%), reporting bias assessment (2.8%), certainty of evidence assessment (1.2%), and sensitivity analysis (107, 24.8%). Seven hundred and forty-four non-intervention reviews were included. The overall completeness of reporting in MOOSE and compliance rate of the methodological process in DART were 51.8% and 50.5%, respectively. Non-intervention reviews published in CSSCI journals had higher reporting completeness than those published in non-CSSCI journals (53.3% vs. 50.3%); however, there was no difference in methodological quality (51.0% vs. 50.0%). Most reviews did not report the process and results of selection (80.8%), and 58.9% of reviews did not describe the process of data extraction; only 9.5% assessed the quality of included studies; while none of the reviews examined bias by confounding, outcome reporting bias, and loss to follow-up. An improving trend over time was observed for both intervention and non-intervention reviews in completeness of reporting and methodological quality (PRISMA: β = 0.24, p < 0.01; AMSTAR-2: β = 0.17, p < 0.01; MOOSE: β = 0.34, p < 0.01; DART: β = 0.30, p < 0.01). The number of authors and financial support also have a positive effect on quality.

Completeness of reporting and methodological quality were low in both intervention and non-intervention reviews in Chinese social sciences, especially regarding registration, protocol, risk of bias assessment, and data and code sharing. The sources of literature, number of authors, publication year, and funding source declarations were identified as factors that may influence the quality of reviews. More rigorous standards and guidelines for conducting and reporting reviews are required in social science research as well as more support and incentives for reviewers to adhere to them.

The aim of this study was to perform a systematic literature review of the purpose, design, and use of family trees by family physicians (FPs).

Family trees offer a valuable contribution to understanding the relevance of the patient's family history in comprehensive primary healthcare provision. There is little research on the role of family trees in the everyday practice of FPs. Studies often focus on specific diseases and their context: however, a comprehensive exploration of the usefulness of family trees is crucial for FPs.

A systematic literature review was conducted through a keyword search in the PubMed and Cochrane databases. Based on the inclusion and exclusion criteria selected, 24 studies were identified and a qualitative analysis was performed.

A total of 369 publications were identified across 32 fields. Twenty-four studies were included in the final analysis according to the QUOROM statement. The results underscore the role of family trees and highlight the value of this tool's multidimensionality. The use of this tool directs FPs to consider a genetic cause and a possible referral to a geneticist. The value of a family tree lies in the personalized patient-oriented treatment in connection with hereditary risks for chronic diseases. For FPs, the greatest challenge in treating patients is determining their risk of developing a chronic disease or cancer. Using a family tree can improve the quality of their healthcare.

Postoperative complications are often associated with the severity and duration of intraoperative hypotension. However, the optimal approach for managing intraoperative hypotension remains controversial. The aim of this meta-analysis of randomized controlled trials was to compare the incidence of common postoperative complications with different treatment threshold of hypotension.

We searched PubMed, the Cochrane Database, and Embase from August 2014 to August 2024 for studies comparing different treatment threshold of hypotension (low [mean arterial pressure < 60 mmHg], moderate [60-75 mmHg], and high [> 75 mmHg]). Only randomized controlled trials conducted during 2014-2024 were included in this meta-analysis without language restrictions. Studies with the following characteristics were included: randomized controlled study; involved non-cardiac, non-obstetric surgery; included different blood pressure management strategies; evaluated major postoperative complications; and included acute kidney injury, myocardial injury, altered consciousness, or infection. Data included patient age, type of surgery, group criteria, and adverse events. Mantel-Haenszel method was used for analysis. The primary outcomes were postoperative complications, including acute kidney injury. The secondary outcomes included length of hospital stay and all-cause mortality.

Of the 2160 studies identified, eight randomized controlled trials with 9108 participants were included. No significant differences in postoperative complications were observed between the moderate and high mean arterial pressure treatment threshold groups (risk ratio = 1.0, 95% confidence interval = 0.86-1.18, P = 0.96). Sensitivity analysis confirmed these findings. Length of hospitalization was not significantly different between the groups (standardized mean difference = -0.39; 95% confidence interval = -0.69 to 1.31; P = 0.03). Limited data prevented meta-analysis of mean arterial pressure management at lower treatment thresholds.

The results of this meta-analysis suggest no significant differences in postoperative complications between moderate and high mean arterial pressure management.

Individual identification of unknown deceased is a vital function carried out by medical professionals, thus many tools have been developed or tested towards its end. One of the tools tested and still being tested is post-mortem computed tomography [PMCT]. This review aims to summarise the current state of using PMCT for personal identification beyond odontology. We found that most medicolegal researchers had a positive view of using PMCT for individual identification or for disaster victim identification. They have shown PMCT scans can be compared with a wide range of AM material - ante-mortem computed tomography [AMCT] scans, AM radiographs, or even textual AM medical history - for a successful identification. The use of textual medical history suggests the potential to create an artificial intelligence model that could quickly highlight areas of comparison. Anatomical body structures, pathological changes, or foreign bodies provide bases of comparison when using PMCT for individual identification. We found most (79 %) researchers have used qualitative methods to compare PMCT with AM material. Likewise, researchers so far have focussed on the axial skeleton (sans pelvis) when testing the viability of comparing specific body structures between AM material and PMCT scans. More body structures remain to be tested for their viability in personal identification, especially using quantitative methods.

While women tend to experience more severe psychiatric and neurobehavioral symptoms following traumatic brain injury (TBI), the connection between sex and post-TBI depression remains poorly understood. To explore the potential association between sex and post-TBI depression, we conducted a systematic review and meta-analysis, including studies with participants who had no prior diagnosis of depression. Thirteen studies met the criteria for inclusion, collectively investigating a cohort of 449,471 individuals with TBI. The median age of the subjects was 49.9 years (≥7 years old). All participants were observed across a spectrum of TBI severities, encompassing mild, moderate, and severe cases. A pooled analysis of 449,471 subjects, revealed a statistically significant difference in the risk of developing post-TBI depression between male and female patients, with females at a significantly higher risk compared to males (RR = 1.4 [95 % CI, 1.29-1.52], P <.0001; I2 = 90.8 %, P <.0001). This significance also appeared in mild TBI/concussion cases (RR = 1.44 [95% CI, 1.36-1.52], P < .0001; I2 = 0%, P = .9), and in depression after a longer period (≥ 24 months) following the TBI (RR = 1.6 [95% CI, 1.59-1.66], P < .0001; I2 = 0%, P = 1). These findings identify TBI as a consistent risk factor for depression, regardless of its severity or type.

The incidence and mortality of lung cancer is the highest among malignant tumors worldwide, and it seriously threatens human life and health. Surgery is the primary radical treatment for lung cancer. However, patients often experience discomfort, changes in social roles, economic pressures, and other postsurgical challenges. These factors frequently cause various psychological disorders such as anxiety and depression, significantly diminishing the quality of life and elevating the risks of recurrence, metastasis, and mortality. Therefore, effective strategies for mental function rehabilitation should be urgently developed. Traditional Chinese medicine can significantly improve psychological function and physical symptoms after lung cancer surgery, and prolong patient survival. However, its effectiveness for mental function rehabilitation after lung cancer surgery remains unclear. This study aimed to investigate the effects of Chinese medicine on mental function recovery after lung cancer surgery through a systematic review and meta-analysis.

This study will systematically search the following databases: PubMed, Cochrane Library, EMBASE, Web of Science, ClinicalTrials.gov, China National Knowledge Infrastructure, Wanfang database, VIP database, and Chinese BioMedical Literature database. Search for studies published from the inception of each database until April 22, 2024. This study will be limited to clinical randomized controlled trials (RCTs). The primary outcome will be depression or anxiety, as indicated by the scale score. Data analysis will be performed using RevMan 5. The Cochrane Risk of Bias Assessment Tool will be used to evaluate the quality of included studies. Finally, the quality of the evidence will be classified using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) System.

This meta-analysis aims to offer comprehensive evidence of the effectiveness of traditional Chinese medicine in mental function rehabilitation after lung cancer surgery. The study will assess the quality of the reports and conduct a subgroup analysis based on various postoperative stages, intervention measures, intervention duration, and sex to gather more evidence to fill the gap in psychological function rehabilitation after lung cancer surgery. These data can be used to guide clinical practice and inform future studies. More importantly, the results of this study will provide evidence to support the development of expert consensus and clinical guidelines in the field of mental function rehabilitation after lung cancer surgery.

Coronary artery disease (CAD) is a main cause of morbidity and mortality. The effectiveness of coronary revascularization in chronic coronary syndromes (CCS) is still debated. Our recent study showed the superiority of coronary revascularization over optimal medical therapy (OMT) in reducing cardiovascular (CV) mortality and myocardial infarction (MI). The recent publication of the ORBITA-2 trial suggested superiority of percutaneous coronary revascularization (PCI) in reducing angina and improving quality of life. Therefore, we aimed to provide an updated meta-analysis evaluating the impact of PCI on both clinical outcomes and angina in CCS.

Relevant studies were screened in PubMed/Medline until 08/01/2024. Randomized controlled trials (RCTs) comparing PCI to OMT in CCS were selected. The primary outcome was CV death. Secondary outcomes were MI, all-cause mortality, stroke, major bleeding and angina severity.

Nineteen RCTs involving 8616 patients were included. Median follow-up duration was 3.3 years. Revascularization significantly reduced CV death (4.2% vs. 5.5%; OR = .77; 95% CI .62-.96, p = .02). Subgroup analyses favoured revascularization in patients without chronic total occlusions (CTOs) (p = .052) and those aged <65 years (p = .02). Finally, a follow-up duration beyond 3 years showed increased benefit of coronary revascularization (p = .04). Secondary outcomes analyses showed no significant differences, except for a lower angina severity in the revascularization group according to the Seattle Angina Questionnaire (SAQ) (p = .04) and to the Canadian Cardiovascular Society (CCS) classification (p = .005).

PCI compared to OMT significantly reduces CV mortality and angina severity, improving quality of life in CCS patients. This benefit was larger without CTOs, in patients aged <65 years and with follow-up duration beyond 3 years.

Family medicine, vital for patient care but underfunded, prompts an evaluation of how family medicine journals endorse, require, and advocate for reporting guidelines (RGs), clinical trial, and systematic review registration.

Assess endorsement and requirement of RGs, and the stance on registration of clinical trials and systematic reviews in family medicine journals, impacting research quality and transparency.

A cross-sectional analysis of 43 'family practice' journals, identified through the 2021 Scopus CiteScore, was undertaken. Editors-in-chief were contacted to confirm article types. Data extracted from 'instructions to authors' pages focused on recommendations or requirements for use of RGs, and for trial registration.

To ensure confidentiality and prevent bias, authors independently extracted data on the requirement or recommendation for use of RGs and clinical trial registration to provide an overview of research standards.

From the 43 journals, the most recommended guidelines were CONSORT (69%), PRISMA (58%), and STROBE (60%). The most required were PRISMA (16%) and CONSORT (11%). Clinical trial registration was recommended or required by 67% of journals. Additionally, 40 out of the 43 (93%) journals cited at least one reporting guideline in their instructions to authors.

Family medicine journals exhibit a variety of endorsement and requirement patterns for RGs and clinical trial registration. While guidelines like CONSORT, PRISMA, and STROBE are acknowledged, caution is needed in presuming a direct link between mention of these RGs and enhanced research quality. A nuanced approach, promoting diverse RGs and rigorous study registration, is essential for elevating transparency and advancing research standards in family medicine.

Research waste is present in all study designs and can have significant consequences for science, including reducing the reliability of research findings and contributing to the inefficient use of resources. Estimates suggest that as much as 85% of all biomedical research is wasted. However, it is uncertain how avoidable research waste is assessed in specific types of study designs and what methods could be used to examine different aspects of research waste. We aimed to investigate which methods, systematic reviews, scoping reviews, and overviews of reviews discussing research waste, have used to assess avoidable research waste.

We published a protocol in the Open Science Framework prospectively (https://osf.io/2fbp4). We searched PubMed and Embase with a 30-year limit (January 1993-August 2023). The concept examined was how research waste and related synonyms (e.g., unnecessary, redundant, duplicate, etc.) were assessed in reviews with a systematic search: systematic, scoping, or overviews of reviews. We extracted data on the method used in the review to examine for research waste and for which study design this method was applied.

The search identified 4,285 records of which 93 reviews with systematic searches were included. The reviews examined a median of 90 (range 10-6,781) studies, where the study designs most commonly included were randomized controlled trials (48%) and systematic reviews (33%). In the last ten years, the number of reports assessing research waste has increased. More than 50% of examined reviews reported evaluating methodological research waste among included studies, typically using tools such as one of Cochrane Risk of Bias tools (n = 8) for randomized controlled trials or AMSTAR 1 or 2 (n = 12) for systematic reviews. One fourth of reviews assessed reporting guideline adherence to e.g., CONSORT (n = 4) for randomized controlled trials or PRISMA (n = 6) for systematic reviews.

Reviews with systematic searches focus on methodological quality and reporting guideline adherence when examining research waste. However, this scoping review revealed that a wide range of tools are used, which may pose difficulties in comparing examinations and performing meta-research. This review aids researchers in selecting methodologies and contributes to the ongoing discourse on optimizing research efficiency.

Bleeding after cardiac surgeries holds risk of mortality and morbidity in pediatrics. This systematic review aimed to evaluate postoperative blood loss and blood transfusion requirements for pediatric patients undergoing cardiac surgery with fresh frozen plasma (FFP) priming.

In 2024, the search reviewed four databases on randomized trials (RCTs) examining the impact of FFP prime intervention on 24-h postoperative blood loss and transfusion requirements in pediatric cardiac surgeries. The journals were appraised using Grading of Recommendation Assessment, Development, and Evaluation checklists, and random effects models estimated the effect size with a 95% confidence interval. Significance and study heterogeneity were indicated by p-values and I2.

Of the screened 2070 articles, one high-quality and four moderate-quality RCTs involving 354 children were identified. No significant reduction in 24-h mean postoperative blood loss was found following FFP priming (mean difference MD: -0.78, 95% CI [-3.3 to 1.75], p = .55) in general pediatric cardiac surgeries. However, subgroup analysis showed significant decrease in blood loss for younger children (<7 months) or those with lower body weight (<6 kg). There was no significant difference between groups in FFP (MD: -0.19, 95% CI [-0.42 to 0.05], p = .13) or red blood cell transfusion (MD: -0.25, 95% CI [-0.51 to 0.02], p = .07).

Administering FFP as prime fluid in cardiac surgery did not reduce postoperative bleeding in general pediatric patients, but younger children (<7 months) and those with lower weight (<6 kg) were the subjects who benefited from the FFP priming before surgery.

In the 2021 Transcatheter Valve Therapy (TVT) registry, 8.9 % of patients underwent TAVR via access sites other than the femoral artery. Transthoracic approaches may be contraindicated in some patients and may be associated with poorer outcomes. Therefore other alternative access routes are increasingly being performed. We conducted a systematic review of the literature on transcarotid transcatheter aortic valve replacement (TC-TAVR) and meta-analysis comparing outcomes of TC-TAVR and other access routes.

We comprehensively searched for controlled randomized and non-randomized studies from 4 online databases. We presented data using risk ratios (95 % confidence intervals) and measured heterogeneity using Higgins' I2.

Sixteen observational studies on transcarotid TAVR were included in the analysis; 4 studies compared TC-TAVR vs TF-TAVR. The mean age and STS score for patients undergoing TC-TAVR were 80 years and 7.6 respectively. For TF-TAVR patients, mean age and STS score were 81.2 years and 6.5 respectively. There was no difference between patients undergoing TC-TAVR and TF-TAVR in the following 30-day outcomes: MACE [8.4 % vs 6.7 %; OR 1.32 (95 % CI 0.71-2.46 p = 0.38) I2 = 0 %], mortality [5.6 % vs 4.0 %; OR 0.42 (95 % CI 0.60-3.37, P = 0.42) I2 = 0 %] and stroke [0.7 % vs 2.3 %; OR 0.49 (95 % CI 0.09-2.56, P = 0.40) I2 = 0 %]. There was no difference in 30-day major vascular complications [0.7 % vs 3 %; OR 0.55 (95 % CI 0.06-5.29, P = 0.61) I2 = 39 %], major bleeding [0.7 % vs 3.8 %; OR 0.39 (95 % CI 0.09-1.67, P = 0.21) I2 = 0 %], and moderate or severe aortic valve regurgitation [8.6 % vs 9.9 %; OR 0.89 (95 % CI 0.48-1.65, P = 0.72) I2 = 0 %].

There are no significant differences in mortality, stroke MACE and major or life-threatening bleeding or vascular complications when TC-TAVR is compared to TF-TAVR approaches.

Neuroimaging plays a crucial role in understanding brain structure and function, but the lack of transparency, reproducibility, and reliability of findings is a significant obstacle for the field. To address these challenges, there are ongoing efforts to develop reporting checklists for neuroimaging studies to improve the reporting of fundamental aspects of study design and execution. In this review, we first define what we mean by a neuroimaging reporting checklist and then discuss how a reporting checklist can be developed and implemented. We consider the core values that should inform checklist design, including transparency, repeatability, data sharing, diversity, and supporting innovations. We then share experiences with currently available neuroimaging checklists. We review the motivation for creating checklists and whether checklists achieve their intended objectives, before proposing a development cycle for neuroimaging reporting checklists and describing each implementation step. We emphasize the importance of reporting checklists in enhancing the quality of data repositories and consortia, how they can support education and best practices, and how emerging computational methods, like artificial intelligence, can help checklist development and adherence. We also highlight the role that funding agencies and global collaborations can play in supporting the adoption of neuroimaging reporting checklists. We hope this review will encourage better adherence to available checklists and promote the development of new ones, and ultimately increase the quality, transparency, and reproducibility of neuroimaging research.

To assess the effects of antibiotics delivered via the respiratory tract in preventing ventilator-associated pneumonia (VAP).

We searched PubMed, Scopus, the Cochrane Library, and ClinicalTrials.gov for studies published in English up to October 25, 2023.

Adult patients with mechanical ventilation of over 48 h and receiving inhaled or instilled antibiotics (with control group) to prevent VAP were included.

Two independent groups screened studies, extracted the data, and assessed the risk of bias. The Grading of Recommendations Assessment, Development, and Evaluation approach was used to assess the certainty/quality of the evidence. Results of a random-effects model were reported for overall and predefined subgroup meta-analyses. The analysis was primarily conducted on randomized controlled trials, and observational studies were used for sensitivity analyses.

Seven RCTs with 1445 patients were included, of which six involving 1283 patients used nebulizers to deliver antibiotics. No obvious risk of bias was found among the included RCTs for the primary outcome. Compared with control group, prophylactic antibiotics delivery via the respiratory tract significantly reduced the risk of VAP (risk ratio [RR], 0.69 [95% CI, 0.53-0.89]), particularly in subgroups where aminoglycosides (RR, 0.67 [0.47-0.97]) or nebulization (RR, 0.64 [0.49-0.83]) were used as opposed to other antibiotics (ceftazidime and colistin) or intratracheal instillation. No significant differences were observed in mortality, mechanical ventilation duration, ICU and hospital length of stay, duration of systemic antibiotics, need for tracheostomy, and adverse events between the two groups. Results were confirmed in sensitivity analyses.

In adult patients with mechanical ventilation for over 48 h, prophylactic antibiotics delivered via the respiratory tract reduced the risk of VAP, particularly for those treated with nebulized aminoglycosides.

Journals have experienced a significant rise in submissions of systematic reviews and other types of reviews that often fall short of acceptable quality standards. These shortcomings typically stem from insufficient rigor in their methodology, reporting, or critical appraisal. As a result, these submissions are frequently rejected raising concerns about the standards authors are following when preparing such work. This growing trend of low-quality reviews not only places a burden on editorial teams but also poses a risk to the scientific community by potentially disseminating flawed or unreliable conclusions. Ensuring that articles maintain high standards is crucial for preserving the integrity of the scientific literature and facilitating evidence-based decision-making. In an effort to address this problem, this viewpoint editorial aims to offer concepts and recommendations on available tools for future authors to improve the quality of their reviews, as well as to guide readers and potential journal reviewers on how to critically interpret these articles.

This meta-analysis aimed to evaluate the effectiveness and adverse effects of specific immunotherapy (SIT) in the management of respiratory allergens, including allergic asthma, rhinitis, and related disorders, based on a review of current literature up to November 8, 2022.

We conducted a search of databases, including PubMed, Embase, Cochrane, and Web of Science, to identify relevant randomized controlled trials (RCTs) assessing respiratory allergy-specific immunotherapy. We employed the Consolidated Standards of Reporting Trials (CONSORT) Statement to select RCTs that adhered to rigorous reporting standards. Specifically, we focused on double-blind placebo-controlled (DBPC) trials and open studies involving both adults and children, considering factors such as dosage, inclusion criteria, allergens, and primary outcome measurements.

A total of 25 meta-analyses were included in this study. Among them, 14 evaluated sublingual-specific allergen immunotherapy (SLIT), 4 assessed subcutaneous allergen immunotherapy (SCIT), 4 explored both sublingual and subcutaneous immunotherapy, and 3 investigated intralymphatic immunotherapy. The outcomes of these meta-analyses indicated a reduction in medication scores in 20 cases and a decrease in symptom scores in 23 cases. Additionally, six studies reported on changes in IgE levels, seven studies focused on IgG4, four studies examined FEV1 (forced expiratory volume in 1 s), and eight studies reported on symptom and medication scores. Furthermore, 11 studies reported on differences in adverse reactions.

The results of our meta-analysis suggest that specific immunotherapy, while associated with some adverse effects, effectively reduces the symptoms of asthma and rhinitis. Therefore, we recommend its use in the treatment of respiratory allergies.

Initiation of feeding after percutaneous endoscopic gastrostomy (PEG) placement has been debated. Randomized controlled trials (RCTs) have been performed on early feeding compared with delayed feeding after PEG placement with varying results. Therefore, a meta-analysis was conducted examining early vs delayed feeding after placement of a PEG.

A comprehensive search of databases was conducted in January 2024. Peer-reviewed published RCTs comparing early feeding (≤4 h) with delayed feeding (>4 h) were identified and included in the meta-analysis. Meta-analysis was completed using pooled estimates of overall complications, individual complications, mortality ≤72 h, and number of day 1 significant gastric residual volumes.

Six RCTs (n = 467) were included in the analysis. Comparison of early feeding with delayed feeding after PEG showed no statistically significant differences for overall complications (P = 0.18), mortality ≤72 h (P = 0.3), and number of day 1 significant gastric residual volumes (P = 0.05). No differences were also noted for individual complications, including vomiting, wound infection, bleeding, or diarrhea.

Feeding ≤4 h after PEG have no differences in minor and major complications compared with that of delayed feeding. Early feeding ≤4 h is safe and should be recommended in future guidelines.

Periodontitis is a chronic infectious-inflammatory pathology, with a high prevalence, which destroys the dental support and, if left untreated, leads to tooth loss. It is associated with other pathologies, particularly diabetes mellitus.

Our objective was to conduct a review of systematic reviews with meta-analyses to determine the evidence for periodontal treatment on periodontitis and diabetes. Second, we assessed the risk of bias and methodological quality using the AMSTAR-2 and ROBIS tools.

We performed bibliographic searches in PubMed/Medline, Embase, Cochrane Central, Dentistry & Oral Sciences Source databases and in the Web of Science (WOS) scientific information service to identify systematic reviews with meta-analyses from the last five years.

Eighteen studies that met the inclusion criteria and evaluated 16,247 subjects were included. The most studied parameters were probing pocket depth, clinical attachment level, bleeding on probing and the glycated hemoglobin. Most of the included meta-analyses evaluated adult patients with periodontitis and type 2 diabetes mellitus (T2DM). Most of the meta-analyses considered and assessed by AMSTAR-2 showed significant methodological errors. The risk of bias was the domain with the worst assessment with the ROBIS tool.

Despite the weaknesses of the included meta-analyses in terms of methodological quality and the risk of bias, periodontal treatment and DM treatment appear to contribute to improved clinical outcomes in a bidirectional manner between periodontitis and DM.

To investigate the efficacy of platelet-rich plasma (PRP) as an augmentation in meniscus repair.

A comprehensive search of PubMed, Medline (via EBSCO), ProQuest, and ScienceDirect from January to February 2023 was conducted using the terms "meniscus repair," "PRP," and "meniscus tear." Meta-analyses that investigated the rate of failure after meniscus repair were included. Studies before 2003, not in English, associated procedures during surgery, and animal studies were excluded. The included studies underwent quality appraisal and risk of bias assessment. Data were extracted from each study's text, figures, tables, and associated supplementary files and then analyzed qualitatively.

The failure rate is lower in the PRP augmentation group compared with the group without augmentation, with a mean difference of 0.42, 0.50, and 0.43. Visual analog scale score was also found to be significantly lower in the treatment group, with a mean difference of 0.40, 0.76, and 6.69. However, only mean differences in Lysholm score in one of the included studies were found significant regarding functional outcomes, which can be found in the Xie et al. study with a mean difference of 3.06.

In this study, we found that meniscal repairs augmented with PRP have a lower failure rate.

Level IV, systematic review of Level III-IV studies.

Despite significant advances in surgical techniques and perioperative care, people undertaking cardiac surgery due to cardiovascular disease are more prone to the development of postoperative adverse events. Statins (5-hydroxy-3-methylglutaryl-co-enzyme A (HMG-CoA) reductase inhibitors) are well-known for their anti-inflammatory and antioxidant effects and are established for primary and secondary prevention of coronary artery disease. In addition, statins are thought to have clinical benefits in perioperative outcomes in people undergoing cardiac surgery. This review is an update of a review that was first published in 2012 and updated in 2015.

To evaluate the benefits and harms of preoperative statin therapy in adults undergoing cardiac surgery compared to standard of care or placebo.

We performed a search of the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 9, 2023), Ovid MEDLINE (1980 to 14 September 2023), and Ovid Embase (1980 to 2023 (week 36)). We applied no language restrictions.

We included all randomised controlled trials (RCTs) comparing any statin treatment before cardiac surgery, for any given duration and dose, versus no preoperative statin therapy (standard of care) or placebo. We excluded trials without a registered trial protocol and trials without approval by an institutional ethics committee.

We used standard Cochrane methodology. Primary outcomes were short-term mortality and major adverse cardiovascular events. Secondary outcomes were myocardial infarction, atrial fibrillation, stroke, renal failure, length of intensive care unit (ICU) stay, length of hospital stay and adverse effects related to statin therapy. We reported effect measures as risk ratios (RRs) or mean differences (MDs) with corresponding 95% confidence intervals (CIs). We used the RoB 1 tool to assess the risk of bias in included trials, and GRADE to assess the certainty of the evidence.

We identified eight RCTs (five new to this review) including 5592 participants. Pooled analysis showed that statin treatment before surgery may result in little to no difference in the risk of postoperative short-term mortality (RR 1.36, 95% CI 0.72 to 2.59; I2 = 0%; 6 RCTs, 5260 participants; low-certainty evidence; note 2 RCTs reported 0 events in both groups so RR calculated from 4 RCTs with 5143 participants). We are very uncertain about the effect of statins on major adverse cardiovascular events (RR 0.93, 95% CI 0.77 to 1.13; 1 RCT, 2406 participants; very low-certainty evidence). Statins probably result in little to no difference in myocardial infarction (RR 0.88, 95% CI 0.73 to 1.06; I2 = 0%; 5 RCTs, 4645 participants; moderate-certainty evidence), may result in little to no difference in atrial fibrillation (RR 0.87, 95% CI 0.72 to 1.05; I2 = 60%; 8 RCTs, 5592 participants; low-certainty evidence), and may result in little to no difference in stroke (RR 1.47, 95% CI 0.90 to 2.40; I2 = 0%; 4 RCTs, 5143 participants; low-certainty evidence). We are very uncertain about the effect of statins on renal failure (RR 1.04, 95% CI 0.80 to 1.34; I2 = 57%; 4 RCTs, 4728 participants; very low-certainty evidence). Additionally, statins probably result in little to no difference in length of ICU stay (MD 1.40 hours, 95% CI -1.62 to 4.41; I2 = 43%; 3 RCTs, 4528 participants; moderate-certainty evidence) and overall hospital stay (MD -0.31 days, 95% CI -0.64 to 0.03; I2 = 84%; 5 RCTs, 4788 participants; moderate-certainty evidence). No study had any individual risk of bias domain classified as high. However, two studies were at high risk of bias overall given the classification of unclear risk of bias in three domains.

In this updated Cochrane review, we found no evidence that statin use in the perioperative period of elective cardiac surgery was associated with any clinical benefit or worsening, when compared with placebo or standard of care. Compared with placebo or standard of care, statin use probably results in little to no difference in MIs, length of ICU stay and overall hospital stay; and may make little to no difference to mortality, atrial fibrillation and stroke. We are very uncertain about the effects of statins on major harmful cardiac events and renal failure. The certainty of the evidence validating this finding varied from moderate to very low, depending on the outcome. Future trials should focus on assessing the impact of statin therapy on mortality and major adverse cardiovascular events.

The safety and efficacy of endovascular coiling of ruptured tiny saccular intracranial aneurysms (IAs) (≤3 mm) remain unknown.

A comprehensive search of PubMed, Embase, Web of Science, and Scorpus databases up to November 15, 2023 was performed. Pooled prevalence was calculated for occlusion rates, recanalization, retreatment, long-term favorable outcome, and procedure-related complications and mortality. Pooled odds ratios were calculated to compare these outcomes between coiling and stent-assisted coiling (SAC).

Forty-two studies with 2166 ruptured tiny saccular IAs treated with coiling were included. The follow-up complete aneurysm occlusion rate was 83.9% (95% CI: 77.2-88.9%). The rates of recanalization and retreatment were 7.7% (95% CI: 5.7-10.2%) and 5.8% (95% CI: 4.5-7.5%). The range of median Hunt and Hess grades was 1.4-2.9 and the favorable outcome rate was 85.6% (95% CI: 81.1-89.2%). The rates of thromboembolism, intraprocedural rupture, and mortality were 4.6% (95% CI: 3.6-5.8%), 5.4% (95% CI: 4.1-7.0%), and 5.6% (95% CI: 4.4-7.2%), respectively. Comparison of coiling and SAC revealed no significant difference, except for a higher likelihood of follow-up complete aneurysm occlusion in SAC (odds ratio [OR] 0.37, 95% CI: 0.17-0.80) and recanalization in the coiling (OR, 3.21 [95% CI, 1.37-7.51]).

Our meta-analysis demonstrates that coiling for ruptured tiny saccular IA is a feasible, effective, and safe approach that is associated with favorable clinical outcomes in both the short and long term for patients with mild to moderate Hunt and Hess grades.

The increasing adoption of real-world studies in healthcare for decision making and planning has further necessitated the need for a specific quality assessment tool for evidence synthesis. This study aimed to develop a quality assessment tool for systematic reviews (SR) and meta-analysis (MA) involving real-world studies (QATSM-RWS) using a formal consensus method. Based on scoping review, the authors identified a list of items for possible inclusion in the quality assessment tool. A Delphi survey was formulated based on the identified items. A total of 89 experts, purposively recruited, with research experience in real-world data were invited to participate in the first round of Delphi survey. The participants who responded in the first Delphi round were invited to participate (n = 15) in the phrasing of the items. Strong level of agreement was found on the proposed list of items after the first round of Delphi. A rate of agreement ≥ 0.70 was used to define which items to keep in the tool. A list of 14 items emerged as suitable for QATSM-RWS. The items were structured under five domains: introduction, methods, results, discussions, and others. All participants agreed with the proposed phrasing of the items. This is the first study that has developed a specific tool that can be used to appraise the quality of SR and MA involving real-world studies. QATSM-RWS may be used by policymakers, clinicians, and practitioners when evaluating and generating real-world evidence. This tool is now undergoing validation process.

To provide a quantitative comparison between myocardial revascularization (REVASC) and optimal medical treatment (OMT) alone in patients with chronic coronary syndrome (CCS).

Pertinent studies were searched for in PubMed/Medline until 12/03/2023. Randomized controlled trials that compare REVASC to OMT reporting clinical outcomes were selected according to PRISMA guidelines. The primary outcome was cardiovascular death. Two investigators independently assessed the study quality and extracted data.

Twenty-eight randomized controlled studies (RCTs) including 20692 patients were included in this meta-analysis. The rate of cardiovascular mortality was significantly lower among patients treated with myocardial revascularization [risk ratio (RR) 0.79, 95% CI 0.69-0.90]. Age (p = 0.03), multivessel disease (p < 0.001), and follow-up duration (p = 0.001) were significant moderators of CV mortality. Subgroup analyses showed a larger benefit in patients treated with drug-eluting stents and those without chronic total occlusion. Among secondary outcomes, myocardial infarction was less frequent in the REVASC group (RR = 0.74; p < 0.001), while no significant difference was found for all-cause mortality (p = 0.09) nor stroke (p = 0.26).

The present analysis showed lower rates of CV mortality and myocardial infarction in CCS patients treated with myocardial revascularization compared to OMT. This benefit was larger with increasing follow-up duration. Personalized treatment based on patient characteristics and lesion complexity may optimize clinical outcomes in patients with CCS.

Left internal mammary artery (LIMA) to bypass left anterior descending artery has demonstrated to improve survival in multivessel coronary artery disease, but its routine angiography during index coronary angiography is seldom performed as LIMA is rarely diseased. A systematic literature review and meta-analysis was conducted using PubMed and Cochrane databases selecting the studies reporting prevalence of LIMA disease among patients undergoing coronary angiography and considered for CABG. Meta-regression analysis was performed to evaluate the prevalence of LIMA disease and the relative predictive value of canonical risk factors. After scrimmage, 9 studies for a total of 1365 patients were included. LIMA disease prevalence was 1.8 % (95 % CI; 1.2 %-2.8 %) in the entire cohort, whereas we reported a rate of subclavian artery disease of 7.6 % (95 % CI, 6-9.9 %). At univariate meta-regression analysis, only age (p = 0.031) and smoking habit (p = 0.035) were directly correlated with LIMA disease. In conclusion, LIMA angiographic assessment might be considered in selected patients that could undergo CABG, during index coronary angiography. However, prospective studies are needed to better evaluate the safety of routine selective LIMA angiography prior to CABG and whether the practice is associated with improved clinical outcomes among those individuals.

Transthoracic approaches may be contraindicated in some patients and may be associated with poorer outcomes. Therefore other alternative access routes are increasingly being performed. We conducted a systematic review of the literature on Transcarotid transcatheter aortic valve replacement (TC-TAVR) and meta-analysis comparing outcomes of TC-TAVR and other access routes.

We comprehensively searched for controlled randomized and non-randomized studies from 4 online databases. We presented data using risk ratios (95 % confidence intervals) and measured heterogeneity using Higgins' I2.

Sixteen observational studies on Transcarotid TAVR were included in the analysis; 4 studies compared 180 TC-TAVR patients vs 524 TT-TAVR patients. The mean age and STS score for patients undergoing TC-TAVR were 80 years and 7.6 respectively. For TT-TAVR patients, the mean age and STS score were 79.7 years and 8.7 respectively. TC-TAVR patients had lower 30-day MACE [7.8 % vs 13.7 %; OR 0.54 (95 % CI 0.29-0.99, P = 0.05)] and major or life-threatening bleeding [4.0 % vs 14.2 %; OR 0.25 (95 % CI 0.09-0.67, P = 0.006)]. There was no significant difference in 30-day: mortality [5.0 % vs 8.6 %; OR 0.61 (95 % CI 0.29-1.30, P = 0.20)], stroke or transient ischemic attack [2.8 % vs 4.0 %; OR 0.65 (95 % CI 0.25-1.73, P = 0.39)] and moderate or severe aortic valve regurgitation [5.0 % vs 4.6 %; OR 1.14. (95 % CI 0.52-2.52, P = 0.75)]. There was a trend towards fewer major vascular complications in TC-TAVR [3.0 % vs 7.8 %; OR 0.42 (95 % CI 0.16-1.12, P = 0.08)].

Compared with transthoracic TAVR, TC-TAVR patients had lower odds of 30-day MACE and life-threatening bleeding and no differences in 30-day mortality, stroke or TIA, aortic valve regurgitation.

Virtual reality (VR) is an emerging method that can be used in many scenarios involving children. VR has been increasingly studied as it has become cheaper, more widely available, and of better quality. In this review of current meta-analyses on the use of VR in children in the medical setting, we examined its role in 5 broad settings where it is used to alleviate pain and anxiety as well as in therapeutic scenarios. The study scope was purposefully broad to highlight a wide range of cases. We searched the ScienceDirect, SpringerLink, Cochrane Library, PubMed, and PMC databases for meta-analyses using VR in pediatric populations in medical settings. The National Institutes of Health quality assessment tool and Quality of Reporting of Meta-analyses statement checklist were used to verify study quality. Six hundred fifty-three articles were retrieved; after the application of the inclusion and exclusion criteria, 11 remained. These meta-analyses included cerebral palsy (4 meta-analyses), attention deficit/hyperactivity disorder (2 meta-analyses), burn care (1 meta-analysis), preoperative anxiety (2 meta-analyses), and needle-involving procedures (2 meta-analyses). The meta-analyses showed broadly positive results, with VR being useful in the areas in which it was applied. This study had several limitations. The meta-analyses consistently highlighted a high level of heterogeneity, making it challenging to draw clear conclusions. Most meta-analyses across all fields yielded encouraging results. However, further studies are required to confirm these findings. Guidelines must be established for future experiments to provide a standard and uniform procedure for reducing the heterogeneity of experimental methods.

This is a protocol for a systematic review and meta-analysis of research on mental health outcomes of abortion. Does abortion increase the risk of adverse mental health outcomes? That is the central question for this review. Our review aims to inform policy and practice by locating, critically appraising, and synthesizing empirical evidence on associations between abortion and subsequent mental health outcomes. Given the controversies surrounding this topic and the complex social, political, legal, and ideological contexts in which research and reviews on abortion are conducted, it is especially important to conduct this systematic review and meta-analysis with comprehensive, rigorous, unbiased, and transparent methods. We will include a variety of study designs to enhance understanding of studies' methodological strengths and weaknesses and to identify potential explanations for conflicting results. We will follow open science principles, providing access to our methods, measures, and results, and making data available for re-analysis.

We explored the current evidence on coronary disease treatment comparing the survival of 2 therapeutic strategies: coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) with drug-eluting stent (DES).

PubMed, Embase, and Google Scholar were searched for randomized clinical trials comparing CABG versus PCI with DES. The end point was overall mortality. Two statistical approaches were used: the generic inverse variance method, which was used to pool the incident rate ratios, and the pooled meta-analysis of Kaplan-Meier-derived individual patient data.

Eight randomized clinical trials comparing 4975 patients undergoing CABG and 4992 patients undergoing PCI were included in our meta-analysis. Generic inverse variance method showed a statistically significant survival benefit of the CABG group (incident rate ratio, 1.21; 95% confidence interval, 1.09-1.35; P < .01). The Kaplan-Meier estimates of survival at 1, 5, and 10 years of the CABG group were 97.1%, 90.3%, and 80.3%, respectively. The Kaplan-Meier estimates of survival at 1, 5, and 10 years of the PCI group were 97.0%, 87.7%, and 76.4%, respectively. The log-rank analysis confirmed a statistically significant benefit in term of overall mortality of the CABG group (hazard ratio, 1.24; 95% confidence interval, 1.11-1.38; P = .0001).

The present meta-analysis suggests that CABG provides a consistent survival benefit over PCI with DES.

Our aims were to, first, identify and summarize the use of methods, frameworks, and tools as a conceptual basis for investigating dimensions of equity impacts of public health interventions in systematic reviews including an equity focus. These include PROGRESS-Plus, which identifies key sociodemographic characteristics that determine health outcomes. Second, we aimed to document challenges and opportunities encountered in the application of such methods, as reported in systematic reviews.

We conducted a methodological study, comprising an overview of systematic reviews with a focus on, or that aimed to assess, the equity impacts of public health interventions. We used electronic searches of the Cochrane Database of Systematic Reviews, the Database of Promoting Health Effectiveness Reviews (DoPHER), and the Finding Accessible Inequalities Research in Public Health Database, supplemented with automated searches of the OpenAlex dataset. An active learning algorithm was used to prioritize title-abstract records for manual screening against eligibility criteria. We extracted and analyzed a core dataset from a purposively selected sample of reviews, to summarize key characteristics and approaches to conceptualizing investigations of equity.

We assessed 322 full-text reports for eligibility, from which we included 120 reports of systematic reviews. PROGRESS-Plus was the only formalized framework used to conceptualize dimensions of equity impacts. Most reviews were able to apply their intended methods to at least some degree. Where intended methods were unable to be applied fully, this was usually because primary research studies did not report the necessary information. A general rationale for focusing on equity impacts was often included, but few reviews explicitly justified their focus on (or exclusion of) specific dimensions. In addition to practical challenges such as data not being available, authors highlighted significant measurement and conceptual issues with applying these methods which may impair the ability to investigate and interpret differential impacts within and between studies. These issues included investigating constructs that lack standardized operationalization and measurement, and the complex nature of differential impacts, with dimensions that may interact with one another, as well as with particular temporal, personal, social or geographic contexts.

PROGRESS-Plus is the predominant framework used in systematic reviews to conceptualize differential impacts of public health interventions by dimensions of equity. It appears sufficiently broad to encompass dimensions of equity examined in most investigations of this kind. However, PROGRESS-Plus does not necessarily ensure or guide critical thinking about more complex pathways, including interactions between dimensions of equity, and with wider contextual factors, and important practical, measurement and conceptual challenges remain. The findings from investigations of equity impacts in systematic reviews could be made more useful through more explicitly rationalized and considered approaches to the design, conduct and reporting of both primary research and the reviews themselves.

In recent years, meta-analysis has evolved to a critically important field of Statistics, and has significant applications in Medicine and Health Sciences. In this work we briefly present existing methodologies to conduct meta-analysis along with any discussion and recent developments accompanying them. Undoubtedly, studies brought together in a systematic review will differ in one way or another. This yields a considerable amount of variability, any kind of which may be termed heterogeneity. To this end, reports of meta-analyses commonly present a statistical test of heterogeneity when attempting to establish whether the included studies are indeed similar in terms of the reported output or not. We intend to provide an overview of the topic, discuss the potential sources of heterogeneity commonly met in the literature and provide useful guidelines on how to address this issue and to detect heterogeneity. Moreover, we review the recent developments in the Bayesian approach along with the various graphical tools and statistical software that are currently available to the analyst. In addition, we discuss sensitivity analysis issues and other approaches of understanding the causes of heterogeneity. Finally, we explore heterogeneity in meta-analysis for time to event data in a nutshell, pointing out its unique characteristics.

Publication bias describes a phenomenon in which significant positive results have a higher likelihood of being published compared to negative or nonsignificant results. Publication bias can confound the estimated therapeutic effect in meta-analyses and needs to be adequately assessed in the surgical literature.

A review of meta-analyses published in five plastic surgery journals from 2002 to 2022 was conducted. The inclusion criteria for meta-analyses were factors that demonstrated an obligation to assess publication bias, such as interventions with comparable treatment groups and enough power for statistical analysis. Acknowledgment of publication bias risk, quality of bias assessment, methods used in assessment, and individual article factors were analyzed.

318 unique meta-analyses were identified in literature search, and after full-text reviews, 143 met the inclusion criteria for obligation to assess publication bias. 64% of eligible meta-analyses acknowledged the confounding potential of publication bias, and only 46% conducted a formal assessment. Of those who conducted an assessment, 49% used subjective inspection of funnel plots alone, while 47% used any statistical testing in analysis. Overall, only 9/143 (6.3%) assessed publication bias and attempted to correct for its effect. Journals with a higher average impact factor were associated with mention and assessment of publication bias, but more recent publication year and higher number of primary articles analyzed were not.

This review identified low rates of proper publication bias assessment in meta-analyses published in five major plastic surgery journals. Assessment of publication bias using objective statistical testing is necessary to ensure quality literature within surgical disciplines.

Introduction: Yoga is a mind-body practice often used to improve health. Systematic reviews (SRs) of randomized controlled trials on yoga for health are foundational to evidence-based yoga interventions and require rigorous and transparent methods, including preparation of a protocol (e.g., PROSPERO) and following SR reporting guidelines (e.g., Preferred Reporting Items for Systematic Reviews and Meta-Analyses [PRISMA]). Objective: To evaluate the availability of protocols and the completeness of reporting for SRs on yoga for health. Methods: We used a previously assembled database of SRs focused on the use of yoga for health. The authors independently extracted data on protocol availability, PROSPERO registration, and reporting for each PRISMA 2009 checklist item. Discrepancies were discussed or referred to a third author. We used Stata 10 software to produce descriptive statistics and tests for relationships between registration, reporting, and publication year, country, and journal type. Results: We included 147 reviews published between 2005 and 2019. The most common first author country was the United States or Germany (total 67/147; 46%), and the most common journal type was specialty journals (71/147; 48%). Most reviews (116/147; 79%) made no mention of a protocol or registration, and only 15/147 (10%) reviews were linked to an accessible protocol or registration. Most SRs published in 2010 or later mentioned or cited PRISMA (97/139; 70%), and individual PRISMA items were addressed between 10% and 100% of the time. PRISMA reporting improved; over time, but there was no relationship with country or journal type. Discussion: This study identifies a need for increased SR registration for yoga research. The assessment of PRISMA reporting did not evaluate the comprehensiveness with which each item was reported, and while trends are encouraging, there is likely room for improvement. We recommend registering all yoga SRs and following updated PRISMA and recent yoga-specific guidelines for reporting. This may increase transparency, minimize bias, and produce high-quality data to inform evidence-based yoga practices.

Based on past epidemiological investigations, the cardiovascular role of estrogen replacement therapy (ERT) in postmenopausal women has always been controversial. The real efficacy of ERT for heart failure (HF) among postmenopausal women remains to be further investigated. This article is based on research into European and American populations.

To determine the impact of estrogen replacement therapy on HF using meta-analysis.

Electronic literature was searched on Web of Science, PubMed, and Embase databases to identify randomized controlled trials (RCTs) comparing the hospitalization for heart failure between ERT users and non-users among postmenopausal women. Pairs of reviewers screened eligible articles independently, extracted data, and evaluated the risk of bias. Summary relative risks were estimated for the composite endpoint of first hospitalized heart failure and admission to the hospital for heart failure.

A pooled study of five randomized controlled trials found that estrogen replacement therapy had no significant effect on the composite endpoint in postmenopausal women, with a relative risk of 1.02 (95% CI 0.94-1.10).

This systematic review demonstrated that estrogen replacement therapy did not significantly change the risk of first hospitalized heart failure and admission to the hospital for heart failure in postmenopausal women.

Pillar pain is a recognized postoperative complication of carpal tunnel release (CTR). Minimally invasive and alternative surgical techniques can theoretically prevent pillar pain, and the aim of this review was to compare the incidence of pillar pain after standard open CTR and alternative surgical techniques.

MEDLINE, Embase, and Scopus databases were thoroughly searched. Randomized controlled trials comparing minimally invasive surgical techniques to standard open CTR were identified. Data, including surgical technique, number of hands, incidence of pillar pain, and follow-up intervals, were extracted. Odds ratios (OR) were expressed as pillar pain incidence in the intervention group relative to standard open CTR.

There were 12 studies included. No statistically significant differences were noted among endoscopic (OR = 0.53, P = .20), flexor retinaculum lengthening (OR = 1.00, P = 1.00), short incision (OR = 0.41, P = .07) or illuminated knife techniques (OR = 0.18, P = .16). There was a statistically significant decrease in pillar pain after minimally invasive CTR (OR = 0.41, 95% confidence interval 0.20-0.86, I2 = 0%, P = .02) between 3- and 6-months follow-up; however, analyses at all other follow-up periods failed to reach statistical significance.

Although our findings suggest that standard open CTR may be associated with an increased duration of pillar pain between 3 and 6 months postoperatively, our results suggest that minimally invasive CTR techniques do not affect either the initial development or persistence of pillar pain.

Our results illustrate the natural history of pillar pain with the majority of cases resolving after 6 months, highlighting the utility of symptomatic and conservative treatments and patient education in the management of pillar pain.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most widely used and prescribed medications because of their important role in reducing inflammation and pain, in addition to their non-addictive properties and safety profiles. However, some studies have documented an association between NSAIDs and delayed union or nonunion of joint arthrodesis procedures due to a potential inhibition of the bone's inflammatory healing response. As a result, some orthopedic surgeons hesitate to prescribe NSAIDs after an arthrodesis procedure. The purpose of this meta-analysis is to review all relevant literature regarding the effect of NSAIDs on union rates after arthrodesis and determine if NSAID therapy increases the risk of non-union in the setting of arthrodesis procedures. The study hypothesis was that NSAIDs would not have a significant effect on the risk of nonunion after arthrodesis. A thorough systematic review of Medline, Embase, the Cochrane Database of Systematic Reviews, and the Web of Science identified 3,050 articles to be screened. The variables of interest encompassed demographic factors, procedural details, type and administration of NSAIDs, the number of patients exposed to NSAIDs with and without successful union (case group), as well as the number of patients who did not receive NSAIDs with and without successful union (control group). All the data were analyzed using a maximum likelihood random-effects model. The number of non-union events versus routine healing from each study was used to calculate the odds ratio (OR) of successful healing after arthrodesis procedures with versus without NSAID therapy. Thirteen articles met the inclusion criteria for the meta-analysis. NSAID exposure showed an increased risk of nonunion, delayed union, or both following arthrodesis procedures; however, this did not meet statistical significance (OR, 1.48; confidence interval [CI], 0.96 to 2.30). A sub-analysis of pediatric and adult studies showed a significant increase in non-union risk in adults (OR, 1.717; CI, 1.012 to 2.914) when removing the pediatric cohort (p = 0.045). This meta-analysis provides evidence that NSAIDs can increase the risk of nonunion, delayed union, or both following arthrodesis procedures in adults. However, the study did not identify a risk of nonunion, delayed union, or both following arthrodesis procedures in the pediatric population.

The optimal revascularization strategy in patients with heart failure with reduced ejection fraction (HFrEF) remains to be elucidated. The aim of this paper is to compare the mid-term mortality rate among patients with severely reduced ejection fraction (EF) and complex coronary artery disease who underwent coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI) with Impella support, or without.

Randomized control trials and propensity-adjusted observational studies including patients with ischemic cardiomyopathy (ICM) and severe EF reduction undergoing revascularization were selected. Different revascularization strategies (CABG, supported PCI, and PCI without Impella) were compared in pairwise and network meta-analysis. The primary endpoint was mid-term mortality (within the first year after revascularization).

Fifteen studies, mostly observational (17,841 patients; 6779 patients treated with CABG, 8478 treated with PCI without Impella, and 2584 treated with Impella-supported PCI) were included in this analysis. The median age was 67.8 years (IQR 65-70.1), 21.2% (IQR 16.4-26%) of patients were female sex, and a high prevalence of cardiovascular risk factors was noted across the entire population. At pairwise analysis, CABG and PCI without Impella showed similar one-year all-cause mortality (10.6% [IQR 7.5-12.6%] vs 12% [IQR 8.4-11.5%]) RR 0.85 CI 0.67-1.09, while supported PCI reduced one-year all-cause mortality compared to PCI without Impella (9.4% [IQR 5.7-12.5%] vs 10.6% [IQR 8.9-10.7%]) RR 0.77 CI 0.6-0.89. At network meta-analysis, supported PCI showed better results (RR 0.75, 95% CI 0.59-0.94) compared to CABG.

Our analysis found that supported PCI may have a benefit over standard PCI in patients in direct comparison, and over CABG from indirect comparison, and with HFrEF undergoing revascularization. Further RCTs are needed to confirm this result. (PROSPERO CRD42023425667).
