Diagnostic Value of Chest Computed Tomography Scan for Identification of Foreign Body Aspiration in Children: A Systematic Review and Meta-analysis.

Introduction: Foreign body aspiration (FBA) is a common, life-threatening pediatric emergency and was shown to be associated with high risk of morbidity and mortality. This systematic review and meta-analysis aimed to investigate the diagnostic value of chest computed tomography (CT) scan for identification of FBA in children. Methods: From inception to May 2024, a systematic search was carried out across multiple databases including Medline, Scopus, and Web of Science, considering published papers in English language. Quality assessment of the included studies was performed using seven domains of Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). Results: The systematic literature search yielded 7203 articles. The pooled sensitivity and specificity of chest CT scan for identification of FBA were 0.99 (95% CI: 0.98-0.99) and 0.97 (95% CI: 0.96-0.98), respectively. The pooled positive likelihood ratio was 10.12 (95% CI: 4.59-22.20), and pooled negative likelihood ratio was 0.05 (95% CI: 0.02-0.1). Furthermore, the area under the summarized receiver operating characteristic (SROC) curve was 0.98. Conclusion: Our meta-analysis revealed that despite high heterogeneity, in the diagnostic characteristics of chest CT scan among studies, it has high diagnostic value in identifying FBA in suspected pediatric cases.

Assessing the Predictive Accuracy of the aMAP Risk Score for Hepatocellular Carcinoma (HCC): Diagnostic Test Accuracy and Meta-analysis.

Purpose: We aimed to perform a meta-analysis with the intention of evaluating the reliability and test accuracy of the aMAP risk score in the identification of HCC. Methods: A systematic search was performed in PubMed, Scopus, Cochrane, Embase, and Web of Science databases from inception to September 2023, to identify studies measuring the aMAP score in patients for the purpose of predicting the occurrence or recurrence of HCC. The meta-analysis was performed using the meta package in R version 4.1.0. The diagnostic accuracy meta-analysis was conducted using Meta-DiSc software. Results: Thirty-five studies 102,959 participants were included in the review. The aMAP score was significantly higher in the HCC group than in the non-HCC group, with a mean difference of 6.15. When the aMAP score is at 50, the pooled sensitivity, specificity, negative likelihood ratio, and positive likelihood ratio with 95% CI was 0.961 (95% CI 0.936, 0.976), 0.344 (95% CI 0.227, 0.483), 0.114 (95% CI 0.087, 0.15), and 1.464 (95% CI 1.22, 1.756), respectively. At a cutoff value of 60, the pooled sensitivity, specificity, negative likelihood ratio, and positive likelihood ratio with 95% CI was 0.594 (95% CI 0.492, 0.689), 0.816 (95% CI 0.714, 0.888), 0.497 (95% CI 0.418, 0.591), and 3.235 (95% CI 2.284, 4.582), respectively. Conclusion: The aMAP score is a reliable, accurate, and easy-to-use tool for predicting HCC patients of all stages, including early-stage HCC. Therefore, the aMAP score can be a valuable tool for surveillance of HCC patients and can help to improve early detection and reduce mortality.

Traumatic Dental Injuries' Prevalence across Diverse Healthcare Settings: A Systematic Review and Meta-Analysis.

Introduction: Traumatic dental injuries (TDI) are a global public health concern, impacting individuals of various age groups. This systematic review aimed to consolidate current evidence on TDI prevalence, providing insights for improved management and prevention strategies. Methods: A comprehensive search was conducted across PubMed/MEDLINE, Embase, and Scopus databases for studies published between January 1, 2000, and July 1, 2024. Studies reporting on the prevalence of TDI in various populations were included. We followed PRISMA guidelines in the review process. Descriptive statistics were used to summarize study characteristics, and a random-effects model was applied in the meta-analysis using STATA version 14 to pool prevalence rates, while accounting for inter-study variability. Begg's and Egger's tests were conducted to assess publication bias. Results: The review included data of 151,205 patients from 30 studies across diverse healthcare settings. The prevalence rates varied significantly across studies, ranging from as low as 1.88% to as high as 86.98%. The overall pooled prevalence of TDI, calculated using a random effects model, was 19.48% (95% CI: 11.21% to 27.74%), indicating substantial heterogeneity among the studies (I-squared = 100.0%, p < 0.001). The prevalence varied significantly across different healthcare settings and demographic groups. No evidence of publication bias was found (p > 0.05). Conclusions: This systematic review underscores the high prevalence of TDI and highlights the need for targeted preventive strategies and evidence-based interventions in dental trauma care.

Evaluating the Efficacy of Immune Checkpoint Inhibitors in Elderly Patients: A Systematic Review and Meta-analysis.

In this chapter, we outline the steps for designing and conducting a rigorous systematic review and meta-analysis, focusing on the efficacy of immune checkpoint inhibitors (ICIs) in elderly patients. ICIs have improved survival rates in advanced cancers, yet their effectiveness in older populations remains unclear. We detail the essential processes involved in both systematic reviews and meta-analyses. We can evaluate the efficacy of ICIs in elderly patients with advanced cancer, examining outcomes such as overall survival and progression-free survival.

Food insecurity and body mass index among older people: A systematic review and meta-analysis.

Food insecurity, characterized by inadequate access to sufficient and nutritious food, poses a significant challenge to the health and well-being of older adults. This systematic review and meta-analysis was aimed to examine the association between food insecurity and body mass index (BMI) in older people, i.e., aging 60 and above. PRISMA 2020 guidelines were followed. The protocol was registered in PROSPERO in advance (ID CRD 42024543271). PubMed/MEDLINE, and Scopus were searched up to February 2024. Out of 5834 retrieved article, a total of 13 studies met the inclusion criteria, encompassing diverse geographic regions and socioeconomic contexts. The meta-analysis revealed a significant association between food insecurity and higher BMI (both obesity and overweight) in older adults. Pooled estimates indicated that food-insecure older individuals were more likely to be overweight or obese (combined) compared to their food-secure counterparts [OR= 1.29 (95% CI= 1.28-1.30), p<0.001; I2= 94.92]. Results were also confirmed for overweight or obesity alone. Notably, food insecurity was linked to increased consumption of energy-dense, nutrient-poor foods, contributing to higher BMI. These findings underscore the complex relationship between food insecurity and BMI among older adults, emphasizing the need for targeted interventions to address food access and nutritional quality.

Factors associated with cognitive impairment in patients with atrial fibrillation: A systematic review and meta-analysis.

BACKGROUND: Atrial fibrillation (AF) is associated with an increased risk of cognitive impairment. Therefore, exploring factors which may be associated with cognitive impairment is important. Correspondingly, this study aimed to systematically evaluate factors associated with cognitive impairment in AF patients by synthesizing relevant evidence. METHODS: A database search of the PubMed, Embase, Cochrane Library, Web of Science, CBM, CNKI, Wanfang, and VIP databases was conducted from inception until December 21, 2023. The effect size was expressed as a combined odds ratio (OR) and 95 % confidence interval (95 % CI). The heterogeneity was qualitatively analyzed by Cochran's Q test and quantified by the I2 statistic. RESULTS: A total of 7,128 studies were identified from the 8 databases, and 39 studies of 3,491,423 participants were included. A meta-analysis was performed on 19 influencing factors. Advanced age (OR=1.38, 95 % CI: 1.11-1.71), female sex (OR=2.19, 95 % CI: 1.18-4.06), smoking (OR=2.44, 95 % CI: 1.24-4.80), hypertension (OR=1.61, 95 % CI: 1.27-2.03), diabetes (OR=1.42, 95 % CI: 1.20-1.67), and hearing impairment (OR=1.37, 95 % CI: 1.05-1.81) were risk factors for cognitive impairment. A higher education level (OR=0.57, 95 % CI: 0.46-0.72), oral anticoagulants (OR=0.61, 95 % CI: 0.48-0.78), novel oral anticoagulants (OR=0.63, 95 % CI: 0.54-0.73), warfarin (OR=0.55, 95 % CI: 0.39-0.79), novel oral anticoagulants relative to warfarin (OR=0.88, 95 % CI: 0.81-0.97), catheter ablation (OR=0.74, 95 % CI: 0.58-0.94) and exercise (OR=0.66, 95 % CI: 0.61-0.72) were protective factors for cognitive impairment. CONCLUSIONS: Age, sex, education level, smoking, exercise, hypertension, diabetes, hearing impairment, anticoagulation therapy, and catheter ablation were associated with cognitive impairment in AF patients.

Overview of the prevalence of loneliness and associated risk factors among older adults across six continents: A meta-analysis.

BACKGROUND: Globally, loneliness is a growing public health concern associated with poor mental and physical health among older adults. Therefore, we performed a meta-analysis to explore the prevalence of loneliness and associated risk factors among older adults across six continents. METHODS: Web of Science, PubMed, Embase, CINAHL, Cochrane Library, and references lists were comprehensively searched until April 2024. Data analysis was performed using Logit Transformation model in R-Software for pooled prevalence and DerSimonian-Lard random-effects model in Comprehensive Meta-Analysis for associated factors of loneliness. Heterogeneity was quantified by I2 and τ2 statistics. The funnel plot and Egger's regression test assessed publication bias. RESULTS: A total of 70 studies with 462,083 older adults were included. The pooled prevalence of loneliness was 26 % (95 %CI, 23 %-30 %) with 38 % for North America, 34 % for Africa, 32 % for Asia and South America, 23 % for Europe, and 13 % for Oceania. Cognitive impairment (2.98; 95 %CI, 1.30-6.81), poor health (2.35; 95 %CI, 1.59-3.45), female (1.92; 95 %CI, 1.53-2.41), depression (1.74; 95 %CI, 1.40-2.16), widowed (1.67; 95 %CI, 1.13-2.48), single (1.51; 95 %CI, 1.06-2.17), institutionalization (2.95; 95 %CI, 1.48-5.88), rural residency (1.18; 95 %CI, 1.04-1.34) were associated with increased risk of loneliness. Being married (0.51; 95 %CI, 0.31-0.82), male (0.55; 95 %CI, 0.43-0.70), and non-institutionalization (0.34; 95 %CI, 0.17-0.68) were associated with lower risk of loneliness. CONCLUSION: Approximately, three among ten older adults aged ≥ 60 years are lonely worldwide. Early detection, prevention, and management of loneliness among older adults should consider diverse needs using gender-specific approaches.

Influence of different exercise types on vascular endothelial function in middle-aged and older adults - A systematic review and network meta-analysis.

STUDY OBJECTIVES: Against the current backdrop of population ageing, the correlation between cardiovascular diseases and endothelial dysfunction is increasingly important. Exercise, a simple and accessible method of preventing and ameliorating numerous diseases, has been demonstrated to significantly enhance endothelial function. This study aimed to assess the effects of aerobic exercise (AE), resistance exercise (RE), combined exercise (CE) and high-intensity interval training (HIIT) on vascular endothelial function in middle-aged and older adults. Flow-mediated dilation (FMD) is a non-invasive ultrasound technique used to measure endothelial function. Direct and indirect comparisons were used to determine which exercise modality most effectively improved vascular endothelial function in this demographic. METHODS: This comprehensive systematic review and network meta-analysis examined randomised controlled trials (RCTs) comparing the effects of four different exercise interventions (AE, RE, CE and HIIT) to a control intervention on FMD in middle-aged and older adults. RESULTS: The analysis included 20 RCTs involving 1,123 participants. The surface under the cumulative ranking curve (SUCRA) analysis indicated that AE was the most effective in improving FMD (SUCRA = 68.9 %), followed by HIIT (SUCRA = 62.5 %), RE (SUCRA = 58.8 %), CE (SUCRA = 54.9 %) and CON (SUCRA = 4.9 %). CONCLUSIONS: This network meta-analysis of various interventions for FMD in middle-aged and older adults found that AE was the most effective in improving FMD (SUCRA = 68.9 %). These findings suggest that AE could be a valuable intervention in clinical practice for enhancing vascular health in this population.

Optimal strategies for exercise intervention in older people diabetic patients: The impacts of intensity, form, and frequency on glycemic control: An exercise prescription for older people with diabetes.

OBJECTIVE: This study aims to investigate the optimal exercise intensity, type, and weekly duration for improving glycated haemoglobin (HbA1c) and fasting blood glucose (FBG) levels in older people individuals with diabetes. MATERIALS AND METHODS: PubMed, EMBASE, Web of Science and other databases were searched to identify randomised controlled trials (RCTs) starting from January 2000 to February 2024 that reported improved effects on fasting glucose and glycated haemoglobin after different exercises in middle-aged and elderly diabetic patients. Meta-analyses Review Manager V.5.3 was used. RESULTS: Meta-analysis showed that moderate- and high-intensity exercise had a significant effect on HbA1c levels, with a mean difference (MD) of -0.34 (95 % CI: -0.44 ∼ -0.24, p < 0.01) for moderate-intensity exercise and -0.54 (95 % CI: -0.78 ∼ -0.3, p < 0.001) for high-intensity exercise.. Both moderate-intensity and high-intensity exercise demonstrated statistical significance in lowering fasting blood glucose levels (p < 0.001). Additionally, there was no significant difference between aerobic and resistance exercise forms (p= 0.72). Furthermore, for reducing HbA1c levels, engageing in weekly exercise for at least 2.5 hours showed a MD of-0.44(95 % CI:-0.63∼0.25;p<0.001). CONCLUSIONS: In summary, in terms of exercise intensity, medium and high-intensity exercise can significantly reduce HbA1c and FBG levels in middle-aged and older people diabetic patients; in terms of exercise form, the effects of different exercise forms within medium and high-intensity on HbA1c and FBG are not statistically significant; and in terms of exercise time, in moderate-intensity aerobic exercise, older people exercising for more than 2.5 h per week are more beneficial.

Cognitive functioning and falls in older people: A systematic review and meta-analysis.

OBJECTIVE: To identify which cognitive functions and specific neuropsychological assessments predict falls in older people living in the community. METHODS: Five electronic databases were searched until 30/08/2022 for studies assessing the association between specific cognitive functions and faller status (prospective and retrospective), in community-dwelling older people. Risk of bias was assessed with the Newcastle-Ottawa Scale. Meta-analyses synthesised the evidence regarding the associations between different neurocognitive subdomains and faller status. RESULTS: Thirty-eight studies (20 retrospective, 18 prospective) involving 37,101 participants were included. All but one study was rated high or medium quality. Meta-analyses were performed with data from 28 studies across 11 neurocognitive subdomains and four specific neuropsychological tests. Poor cognitive flexibility, processing speed, free recall, working memory and sustained attention were significantly associated with faller status, but poor verbal fluency, visual perception, recognition memory, visuo-constructional reasoning and language were not. The Trail Making Test B was found to have the strongest association with faller status. CONCLUSION: Poor performance in neurocognitive subdomains spanning processing speed, attention, executive function and aspects of memory are associated with falls in older people, albeit with small effect sizes. The Trail Making Test, a free-to-use, simple assessment of processing speed and mental flexibility, is recommended as the cognitive screening test for fall risk in older people.

Prevalence of successful aging in older adults: A systematic review and meta-analysis.

BACKGROUND: Successful aging (SA) describes the multidimensional aspects of achieving optimal physical and mental health and social well-being combinations in old age. Recent years have seen increasing interest in understanding SA prevalence. This study systematically evaluates the current state of SA globally, defined as multidimensional outcomes. OBJECTIVE: To systematically evaluate the global prevalence of SA in older adults. METHODS: We searched PubMed, Embase, Web of Science, Cochrane Library, China Biomedical Database, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and Weipu Database from inception to February 14, 2024. Two researchers independently conducted literature screening, data extraction, and quality evaluation. Meta-analysis was performed using Stata 16.0. RESULTS: Thirty studies comprising 250,460 older adults were included. Meta-analysis showed the overall global prevalence of SA was 24.0 % [95 % CI (20.7 %, 27.3 %)]. Prevalence rates were 25.1 % in Asia, 21.5 % in Europe, 20.6 % in the Americas; 16.8 % in developed and 27.1 % in developing countries. Subgroup analyses indicated higher SA rates among male older adults, married/cohabiting, living in urban areas, and having higher education levels. CONCLUSIONS: The global prevalence of SA among older adults is low, with variations across age groups, regions, and education levels. Due to the limitations of the included studies, further high-quality research is needed to validate these findings.

Retrograde intrarenal surgery with or without ureteral access sheath: a systematic review and meta-analysis of randomized controlled trials

ABSTRACT Introduction: The ureteral access sheath (UAS) is a medical device that enables repeated entrance into the ureter and collecting system during retrograde intrarenal surgery (RIRS). Its impact on stone-free rates, ureteral injuries, operative time, and postoperative complications remains controversial. Therefore, we performed a systematic review and meta-analysis comparing RIRS with versus without UAS for urolithiasis management. Purpose: To compare outcomes from retrograde intrarenal surgery (RIRS) for stone extraction with or without ureteral access sheath (UAS); evaluating stone-free rate (SFR), ureteral injuries, operative time, and postoperative complications. Materials and Methods: We systematically searched PubMed, Embase, and Cochrane Library in June 2024 for randomized controlled trials (RCTs) evaluating the efficacy and safety outcomes of UAS use in RIRS for urolithiasis treatment. Articles published between 2014 and 2024 were included. Pooled risk ratios (RRs) and mean differences (MDs) were calculated for binary and continuous outcomes, respectively. Results: Five RCTs comprising 466 procedures were included. Of these, 246 (52.7%) utilized UAS. The follow-up ranged from 1 week to 1 month. UAS reduced the incidence of postoperative fever (RR 0.49; 95% confidence interval [CI] 0.29-0.84; p=0.009), and postoperative infection (RR 0.50; 95% CI 0.30-0.83; p=0.008). There were no significant differences between groups in terms of SFR (RR 1.05; 95% CI 0.99-1.11; p=0.10), ureteral injuries (RR 1.29; 95% CI 0.95-1.75; p=0.11), operative time (MD 3.56 minutes; 95% CI −4.15 to 11.27 minutes; p=0.36), or length of stay (MD 0.32 days; 95% CI −0.42 to 1.07 days; p=0.40). Conclusion: UAS leads to a lower rate of post-operative fever and infection. However, UAS did not significantly reduce or increase the SFR or the rate of ureteral injuries during RIRS for patients with urolithiasis. The use of UAS should be considered to decrease the risk of infectious complications, particularly in those who may be at higher risk for such complications.

Efectos de la terapia manual en personas con fibromialgia: Revisión sistemática y metaanálisis / Effects of Manual Therapy in People with Fibromyalgia: Systematic Review and Meta-Analysis

Resumen Objetivo: El objetivo de esta revisión sistemática con metaanálisis es sintetizar la evidencia científica disponible sobre los efectos de la terapia manual aplicada de forma aislada en comparación a otras intervenciones en el dolor, la capacidad funcional, la impresión global de mejoría y severidad de síntomas autopercibida en personas con fibromialgia. Metodología: Se realizó una revisión sistemática y metaanálisis con búsqueda electrónica en MEDLINE, WoS, SCOPUS, PEDro, CENTRAL y LILACS. Resultados: Once estudios cumplieron con los criterios de selección y seis fueron incluidos en una síntesis cuantitativa. El dolor al terminar el tratamiento tuvo una diferencia de medias de -0.42 (IC al 95% -1.14, 0.30, p = 0.25), el estado funcional al terminar el tratamiento tuvo una diferencia de medias de -0.15 (IC al 95% -0.69, 0.40, p = 0.60), la impresión global de salud al terminar el tratamiento tuvo una diferencia de media de -1.13 (IC al 95% -1.68, -0.57 p = <0.00) y posterior a doce meses una diferencia de media de -0.48 (IC al 95% -0.78, -0.19 p = <0.00), la impresión global de severidad después de la intervención tuvo una diferencia de medias de -0.62 (IC al 95% -1.22, -0.03, p = 0.04) y posterior a doce meses una diferencia de medias de -0.43 (IC al 95% -1.18, 0.32, p = 0.26). Conclusiones: La terapia manual aislada es una intervención que podría mejorar significativamente la autopercepción del estado global de mejoría y severidad de síntomas a corto plazo en comparación a agentes físicos placebo. Sin embargo, no es mejor que otras intervenciones para disminuir el dolor y mejorar la capacidad funcional.

Abstract Objective: The aim of this systematic review with meta-analysis is to synthesize the available scientific evidence on the effects of manual therapy applied in isolation in comparison to other interventions on pain, functional capacity, global impression of improvement, and self-perceived severity of symptoms in people with fibromyalgia. Methodology: A systematic review with meta-analysis was conducted with electronic search of MEDLINE, WoS, SCOPUS, PEDro, CENTRAL, and LILACS. Results: Eleven studies met the selection criteria and six were included in a quantitative synthesis. Pain at the end of treatment had a mean difference of -0.42 (95% CI -1.14, 0.30, p = 0.25), functional status at the end of treatment had a mean difference of -0.15 (95% CI - 0.69, 0.40, p = 0.60), the global impression of health at the end of treatment had a mean difference of -1.13 (95% CI -1.68, -0.57 p = <0.00) and a mean difference of -0.48 after twelve months (95% CI -0.78, -0.19 p = <0.00), the global impression of severity after the intervention had a mean difference of -0.62 (95% CI -1.22, -0.03, p = 0.04 ) and a mean difference of -0.43 after twelve months (95% CI -1.18, 0.32, p = 0.26). Conclusions: Isolated manual therapy is an intervention that could significantly improve the self-perception of the global state of improvement and severity of symptoms in the short term compared to sham physical agents. However, it is not better than other interventions to reduce pain and improve functional capacity.

Living systematic review and comprehensive network meta-analysis of ALS clinical trials: study protocol.

INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a fatal neurogenerative disease with no effective treatment to date. Despite numerous clinical trials, the majority of studies have been futile in their effort to significantly alter the course of the disease. However, these studies may still provide valuable information for identifying patient subgroups and generating new hypotheses for future research. Additionally, synthesising evidence from these studies may help overcome the limitations of individual studies. Network meta-analysis may refine the assessment of efficacy in specific patient subgroups, evaluate intervention characteristics such as mode of administration or biological mechanisms of action, and rank order promising therapeutic areas of interest. Therefore, we aim to synthesise the available evidence from ALS clinical trials. METHODS AND ANALYSIS: We will conduct a systematic review to identify all clinical trials that assessed disease-modifying pharmaceutical therapies, cell therapies, or supplements in patients with ALS. Outcomes of interest are clinical disease progression outcomes and survival. We will conduct this search in the period Q4 2024 in three databases: PubMed, Embase and ClinicalTrials.gov for studies from 1999 to 2023. Individual patient data and aggregate data will be collected and subsequentially synthesised in meta-analytical models. The final model will be presented as an open-source web application with biannual updates of the underlying data, thereby providing a 'living' overview of the ALS clinical trial landscape. ETHICS AND DISSEMINATION: No ethics approvals are required. Findings will be presented at relevant conferences and submitted to peer-reviewed journals. Data will be stored anonymously in secure repositories.

Augmentation of cognitive-behavioural therapy for obsessive-compulsive and anxiety disorders: a protocol for a systematic review and meta-analysis.

INTRODUCTION: While cognitive-behavioural therapy (CBT) for obsessive-compulsive disorder (OCD) and anxiety disorders (ADs) has been proven to be effective and is commonly recommended, a considerable proportion of patients remain symptomatic, do not respond to treatment or discontinue it. Thus, augmentation strategies aimed at enhancing CBT outcomes are essential to reduce the burden of OCD and ADs on patients and society. Various augmentation strategies for CBT in OCD and ADs have been investigated, yet it remains unclear if they show robust beneficial effects beyond first-line CBT. With this systematic review and meta-analysis, we will provide an overview and critically assess the efficacy of non-pharmacological augmentation strategies in addition to first-line CBT treatment for symptom reduction, response rates and dropout rates in individuals with OCD or ADs. METHODS AND ANALYSIS: We will screen PubMed, Embase, PsycArticles, PsycInfo, CINAHL, PSYNDEX and Cochrane Register of Controlled Trials without restrictions on publication dates or languages. Additionally, forward, and backward searches of included studies and systematic reviews will be conducted. Two reviewers will independently screen the studies, extract data and assess the methodological quality of the studies. We will exclusively include randomised controlled trials. The primary outcomes will be symptom severity and response rates. Dropout rates will serve as a secondary outcome. Moreover, we will provide a narrative review of the results. We will use subgroup and meta-regression analyses to identify potential moderators and sources of between-study heterogeneity. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the overall quality of evidence. ETHICS AND DISSEMINATION: Ethical approval is not required. Results will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42024561027.

Effectiveness of non-pharmacological interventions for pain management in patients with cancer:a protocol for systematic review and network meta-analysis.

INTRODUCTION: Pain management in patients with cancer is a critical aspect of oncological care, yet remains challenging with current pharmacological therapies. Non-pharmacological interventions, offering potential benefits without the adverse effects of drugs, have gained attention. However, the effectiveness of these diverse non-pharmacological interventions is not well understood, creating a gap in clinical practice. This study aims to conduct a systematic review and network meta-analysis (NMA) to evaluate the efficacy of various non-pharmacological interventions for pain management in patients with cancer, providing evidence-based guidance for clinicians and patients. METHODS AND ANALYSIS: A systematic review and Bayesian NMA will be performed. To assess the efficacy of interventions for cancer pain, we will search six electronic databases: Cochrane Library, Web of Science, PubMed, EMBASE, PsycINFO and the Cumulative Index to Nursing and Allied Health Literature, focusing on identifying randomised controlled trials. Literature screening should be independently performed by two reviewers. A NMA will evaluate the efficacy of various non-pharmacological interventions for cancer pain. A second NMA will compare the efficacy of different non-pharmacological interventions in relieving pain interference in patients with cancer pain. Bayesian 95% credible intervals will be used to estimate the pooled mean effect size for each treatment, and the surface under the cumulative ranking area will be employed to rank the effectiveness of the treatments. ETHICS AND DISSEMINATION: Ethical approval is not required for this systematic review of the published data. Findings will be disseminated via peer-reviewed publication. PROSPERO REGISTRATION NUMBER: CRD42024483025.

Safety of diagnostic hysteroscopy for the investigation of type II endometrial cancer: systematic review with meta-analysis.

AIM: The goal of this study is to evaluate the safety of diagnostic hysteroscopy (HSC) in type II endometrial cancer (EC). METHODS: We searched PubMed, the Cochrane Library and the Chinese Medical Journal Full-Text Database until December 2023. Eligible trials were all cohort studies in which patients were allocated to diagnostic HSC group or dilation and curettage (D&C) group. Quality assessments of eligible studies were performed using the Newcastle-Ottawa scales. Risk ratios (RRs) with 95% CIs were calculated as a measure of effects. RESULTS: Three trials were included in our analysis, which were all retrospective cohort studies. 696 patients with histologically proven type II EC were allocated to HSC or D&C before surgery. 257 patients underwent preoperative HSC, and 439 patients underwent D&C. The positive peritoneal cytology rate did not statistically differ between the groups (RR, 1.9; 95% CI, 1.00 to 3.61; p=0.05). There was no significant difference in the incidence of International Federation of Gynecology and Obstetrics (FIGO) stage between the HSC and D&C groups (stage I/II: RR, 1.08; 95% CI, 0.95 to 1.24; p=0.25; stage III/IV: RR, 0.82; 95% CI, 0.62 to 1.09; p=0.18). There was no significant difference in recurrence between the HSC and D&C groups (RR, 0.92; 95% CI, 0.66 to 1.32; p=0.66); the heterogeneity of the two included studies was acceptable (p=0.54, I2=0%). CONCLUSIONS: Preoperative HSC in patients with type II EC does not increase the risk for cancer cell dissemination within the peritoneal cavity. Preoperative HSC does not progress the FIGO staging in patients with type II EC and does not increase the risk of tumour recurrence. There is no reason to avoid HSC for the diagnosis of type II EC currently. However, type II tumours generally are less well differentiated and have poorer prognoses than type I tumours. More prospective and adequately powered trials are required to clarify whether preoperative HSC in patients with type II EC is safe.

Semi-automated title-abstract screening using natural language processing and machine learning.

BACKGROUND: Title-abstract screening in the preparation of a systematic review is a time-consuming task. Modern techniques of natural language processing and machine learning might allow partly automatization of title-abstract screening. In particular, clear guidance on how to proceed with these techniques in practice is of high relevance. METHODS: This paper presents an entire pipeline how to use natural language processing techniques to make the titles and abstracts usable for machine learning and how to apply machine learning algorithms to adequately predict whether or not a publication should be forwarded to full text screening. Guidance for the practical use of the methodology is given. RESULTS: The appealing performance of the approach is demonstrated by means of two real-world systematic reviews with meta analysis. CONCLUSIONS: Natural language processing and machine learning can help to semi-automatize title-abstract screening. Different project-specific considerations have to be made for applying them in practice.

The use of mindfulness-based stress reduction (MBSR) for breast cancer patients-meta-analysis.

BACKGROUND: Mindfulness-based stress reduction (MBSR) intervention has been widely used to reduce the burden of symptoms in cancer patients, and its effectiveness has been proven. However, the effectiveness of MBSR on depression, anxiety, fatigue, quality of life (QOL), posttraumatic growth (PTG), fear of cancer recurrence (FCR), pain, and sleep in breast cancer patients has not yet been determined. This study aims to determine the role of mindfulness-based stress reduction therapy in patients with breast cancer. OBJECTIVES: The objective was to systematically review the literature to explore the effect of MBSR on anxiety, depression, QOL, PTG, fatigue, FCR, pain, stress and sleep in breast cancer patients. To explore the effect of 8-week versus 6-week MBSR on the 9 indicators. Data were extracted from the original RCT study at the end of the intervention and three months after baseline to explore whether the effects of the intervention were sustained. METHODS: We conducted searches on PubMed, Web of Science, Embase, and China National Knowledge Infrastructure from inception to November 2023. Eligible studies included randomized controlled trials of breast cancer patients who received mindfulness stress reduction intervention, reporting outcomes for anxiety, depression, fatigue, QOL, PTG, FCR, pain, stress, and sleep. Two researchers conducted separate reviews of the abstract and full text, extracted data, and independently evaluated the risk of bias using the Cochrane 'Bias Risk Assessment tool'. The meta-analysis utilized Review Manager 5.4 to conduct the study, and the effect size was determined using the standardized mean difference and its corresponding 95% confidence interval. RESULTS: The final analysis included 15 studies with a total of 1937 patients. At the end of the intervention, the interventions with a duration of eight weeks led to a significant reduction in anxiety [SMD=-0.60, 95% CI (-0.78, -0.43), P < 0.00001, I2 = 31%], depression [SMD=-0.39, 95% CI (-0.59, -0.19), P = 0.0001, I2 = 55%], and QOL [542 participants, SMD = 0.54, 95% CI (0.30, 0.79), P < 0.0001, I2 = 49%], whereas no statistically significant effects were found in the intervention with a duration of six weeks. Similarly, in 3 months after baseline, the interventions with a duration of eight weeks led to a significant reduction in depression and QOL, however, no statistically significant effects were found at the 6-week intervention. MBSR led to a significant improvement in PTG at end of intervention [MD = 6.25, 95% CI (4.26, 8.25), P < 0.00001, I2 = 0%] and PTG 3 months after baseline. We found that MBSR reduced the fatigue status at end of intervention, but had no significant effect on fatigue status 3 months after baseline. There was no significant difference in improving pain, stress, and FCR compared to usual care. CONCLUSIONS: In terms of effects on QOL, anxiety, depression, and fatigue, the 8-week MBSR intervention showed better results than the 6-week MBSR intervention. The intervention of MBSR on PTG was effective, and the effect lasted until 3 months after baseline. Future studies could further identify the most effective intervention components in MBSR.

The risk of kidney dysfunction in metabolically healthy/unhealthy population with normal weight or overweight/obesity: a systematic review and meta-analysis.

BACKGROUND: Chronic kidney disease (CKD) is a major global health concern with increasing prevalence and associated complications. Obesity and obesity-related metabolic disorders have been linked to chronic kidney disease (CKD), although the evidence is still inconsistent. To investigate the relationship between different obesity phenotypes and the risk of CKD, we conducted a systematic review and meta-analysis. METHOD: We conducted a comprehensive search of databases for all relevant studies up to February 2024, without imposing a specific start date, for observational studies assessing the relationship between obesity phenotypes and incident kidney dysfunction. We used fixed and random effects models for the meta-analysis, subgroup analyses were carried out to explore heterogeneity, and Egger's and Begg's tests were used to assess publication bias. RESULT: This meta-analysis included 13 eligible observational studies with 492,829 participants. Pooling the studies regardless of the effect measure showed that individuals with metabolically unhealthy normal weight (MUNW) (ES = 1.58, 95% CI = 1.43-1.76), metabolically healthy obese (MHO) (ES = 1.20, 95% CI = 1.06-1.34), and metabolically unhealthy obese (MUO) (ES = 1.90, 95% CI = 1.63-2.20) phenotypes had a significantly increased risk for kidney dysfunction (KD) events. On the other hand, MUOW individuals did not significantly correlate with risk of CKD (ES = 1.63, 95% CI = 0.97-2.23) compared to the MHNW phenotype. CONCLUSION: Healthy overweight and obese individuals had higher risk for the incident KD events; refuting the notion that metabolically healthy overweight and obese phenotypes are benign conditions. LEVEL OF EVIDENCE: III Evidence obtained from well-designed cohort or cross-sectional studies.
