International Prevalence of Technology-Facilitated Sexual Violence Against Women: A Systematic Review and Meta-Analysis of Observational Studies.

The aim of the present review was to systematically identify and examine current knowledge regarding the frequency of any form of technology-facilitated sexual violence (TFSV) perpetrated against women aged 16 years and older. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was applied when performing the present review. Observational studies reporting prevalence data for any form of TFSV against women aged 16 years and above were considered for inclusion. Four meta-analyses were conducted. One examined data pertaining to overall TFSV, while the other three each addressed a key dimension based on the type of victimization under study. Random-effects models were used to compute pooled estimate prevalences (95% CI). Included studies reported prevalence in 32 different countries at different time points, with 28,220 women being interviewed (16-97 years). A total of 1,437 potential articles were gathered from 8 databases and 17 studies were selected for analysis. Included studies exhibited a low risk of bias (12 strong methodological quality-5 medium). Rates of TFSV ranged from 2.2% to 84%. Global estimated prevalence was 30.60% (95% CI [24.08, 37.12]). The most frequently reported behaviors pertained to "digital sexual harassment" (28.54%) followed by "technology-facilitated aggression and coercion" (16.93%) and "image-based sexual abuse" (6.48%). Present findings shed light on a significant gap in understanding the experiences of adult women. The wide range of reported frequencies underscores the importance of unifying terms and standardizing measurement instruments, emphasizing the need for a cohesive approach to better comprehend and address the multifaceted nature of TFSV.

Chronic pain in European adult populations: a systematic review of prevalence and associated clinical features

Abstract Chronic pain (CP) is a multifaceted and severely disabling persistent condition that affects individuals worldwide. A synthesis of epidemiological data is still lacking. The present systematic review aims at presenting point, period, and lifetime prevalence estimates of CP in the European adult population, as well as relevant features associated with it. Following PRISMA guidelines, a systematic search in PubMed, Web of Science, Embase, and Cochrane library was run from inception to May 2024, resulting in 39,832 hits. Among those, 132 full-text articles were assessed, and 23 studies comprising 862,013 participants with CP were included. The Joanna Biggs Institutes' Critical Appraisal Checklist for Studies Reporting Prevalence Data (JBI) was used for quality assessment. Findings showed a point prevalence ranging from 12% to 48%, a 6-month prevalence of 17.5% to 49.8%, a 12-month prevalence ranging from 8.1% to 44.6%, and a lifetime prevalence ranging from 12.7% to 33.7% independently from sex. Sociodemographic factors (eg, female sex, higher age, no partnership, lower education, unemployment) and clinical features (eg, medical diseases, mental disorders and burdens, healthcare utilization, functional impairment) were identified as being associated with CP. The variability in prevalence estimates can be reduced by applying consistent diagnostic criteria (eg, ICD-11) and by using standardized assessment tools (eg, scales, clinical interview). The high prevalence and the characteristics of the associated features support the need for adequate, multicomponent care paths to manage CP based on a comprehensive biopsychosocial model.

Prevalence and genotype distribution of human papillomavirus (HPV) in penile cancer in Brazil

Objective: To estimate the prevalence and genotypic distribution of Human Papillomavirus (HPV) in penile cancer in Brazil. Methods: This is a systematic review and meta-analysis of studies published from 2000 to 2021, that investigated the prevalence and genotypic distribution of HPV in penile cancer in different geographical regions in Brazil, using molecular methods. The review was registered in the International Prospective Register of Systematic Reviews (PROSPERO), conducted in accordance with the Preferred Reporting of Systematic Reviews and Meta-Analysis Statement (PRISMA) and the quality of included studies was assessed by the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Studies Reporting Prevalence Data. Results: 15 studies were included, comprising 1,250 cases. The combined prevalence of HPV in penile cancer was 52.0% and the highest prevalence was observed in the Northeast region (79%), followed by the North region (54%), Southeast (44%) and Central-West region (31%). HPV16 was the most prevalent genotype, followed by HPV6, HPV11, HPV18, HPV51, HPV59, HPV74, HPV31, HPV35 and HPV68. Final considerations: Our results confirm the association of HPV with penile cancer and highlight the presence of viral genotypes not covered by the tetravalent prophylactic vaccine distributed by the public health system in Brazil.

Systematic Review and Meta-Analysis: Iron Deficiency and Iron Deficiency Anemia Among Military Recruits Undergoing Basic Combat Training

ABSTRACT Introduction The first period of military service consists of a physically and mentally challenging basic combat training (BCT) program. Factors like demanding physical exercise, limited recovery time, and restricted diet choice and food intake may challenge iron intake and homeostasis in recruits undergoing BCT. Iron-deficient individuals may experience reduced work capacity, fatigue, weakness, frequent infections, and increased injury risk. Limited knowledge is available on the extent of this potential health risk among military recruits. The aim of the present study was to systematically review published studies on the prevalence and change in prevalence of anemia, iron deficiency (ID), and ID anemia (IDA) among recruits undergoing BCT. Materials and Methods Electronic searches were conducted in the databases Medline (Ovid), Embase (Embase.com), and Web of Science (Clarivate Analytics) from database inception up until April 16, 2024. Inclusion criteria were observational studies with both cross-sectional and observational longitudinal designs that examined the effects of BCT (intervention) on iron status (outcome) in military recruits (population). Extracted data were the number of participants (n), age, sex, country/population, BCT duration, and relevant measures of prevalence and changes in prevalence of anemia, ID, and IDA (primary outcome) and physical performance, mood state, stress fractures, attrition rate, and nutritional supplements (secondary outcomes). The study quality and risk of bias were assessed using the JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data and The National Institutes of Health Quality Assessment Tool for Before-After (Pre-Post) Studies With No Control Group. Meta-analyses were performed using restricted maximum-likelihood models, and the effect size was calculated as Cohen’s h with 95% CI. Results Twenty-two articles were systematically reviewed (n = 111,764 men and 12,650 women), and six of these papers (n = 388 men and 773 women) were included in the meta-analysis. There was a varying prevalence of anemia, ID, and IDA among military recruits at the start of BCT. Results from meta-analyses showed negligible and nonsignificant effects of BCT on the prevalence of anemia, ID, and IDA. The quality of the included cross-sectional studies ranging from fair to good, whereas a large proportion of the included longitudinal studies were classified as poor. No sign of publication bias was found. Conclusions The prevalence of anemia, ID, and IDA in military recruits seems not to be affected by the completion of BCT shorter than 16 weeks, whereas the effects of longer BCT durations remain unclear. Even though body iron homeostasis seems unaffected, adequate energy and nutritional intake should remain a priority. Future research could focus on dietary interventions to determine the optimal diet among female recruits in specifically exposed populations.

Prevalence and factors associated with transfusion-transmissible infections (HIV, HBV, HCV and Syphilis) among blood donors in Gabon: Systematic review and meta-analysis.

Transfusion-transmissible infections (TTIs) remain a major public health problem in countries with limited resources, particularly in Gabon. Complete information on the prevalence in Gabon of the main TTIs among blood donors is still lacking in the national context. The purpose of this systematic review and meta-analysis was to determine the prevalence and factors associated with TTIs among blood donors in Gabon. This systematic review and meta-analysis was reported in accordance with the PRISMA 2020 guidelines. It was the result of data from several comprehensive studies published between 2014 and 2022, the purpose of which focused on the prevalence and factors associated with TTIs among blood donors in Gabon. The quality of the articles was assessed using the Joanna Briggs Institute critical appraisal checklist for studies reporting prevalence data. The overall prevalence of TTIs among blood donors was determined using the random effects model. Heterogeneity between studies was assessed using I2 statistics. Publication bias was assessed by visual inspection of the funnel plot and Egger's statistics. A total of 175,140 blood donors from the nine eligible studies were admitted to this study. The combined prevalence of HIV, HBV, HCV and syphilis obtained in the random effects model was 3.0%, 6.0%, 4.0% and 3.0%, respectively. Moreover, being a male blood donor and aged between 25 and 44 years was significantly associated with HBV infection and being a female blood donor and aged 35 years and over was significantly associated with HIV infection. Family or replacement blood donors had a high infection burden for all four TTIs of study. The overall prevalence of transfusion-transmissible infections remains high in the country's blood banks. Improving current prevention (selection criteria) and screening strategies may be necessary in a global approach.

Prevalence of adherence to oral antidiabetic drugs in patients with type 2 diabetes: A systematic review and meta-analysis.

The treatment of type 2 diabetes requires multidimensional management, with medication adherence a crucial aspect of diabetes control. However, recent rigorous estimates of adherence to oral antidiabetic drugs (OAD) are lacking. The objective of this study is to determine the prevalence of adherence to OAD in type 2 diabetes patients. A systematic search was performed in PubMed, EMBASE, PsycINFO, and CINAHL from July 2013 to April 2023. Cross-sectional studies published in English were included if they met the following criteria: (1) reported the adherence to OAD using a validated measure; and (2) had a sample size of at least 385 patients with type 2 diabetes. The Joanna Briggs Institute critical appraisal for studies reporting prevalence data was used to assess the quality of the included studies. Pooled estimates of the prevalence of adherence to OAD were calculated as a percentage together with 95% confidence interval (95% CI) using a random-effect model. All analyses were conducted using STATA 17.0; PROSPERO (CRD42023414264). Twenty-six studies involving a total of 69,366 patients met the selection criteria and were included in the meta-analysis. The overall estimated prevalence of adherence to OAD was 55.53% (95%CI: 44.22%-66.85%). Among the included studies, nine were deemed to be of high quality. A sensitivity analysis conducted using only the high-quality studies revealed a prevalence of adherence to OAD at 52.24% (95% CI: 39.63%-64.85%). The overall prevalence of adherence to OAD was remarkably low among type 2 diabetes patients worldwide. Healthcare practitioners and policy makers should employ appropriate approaches to improve adherence to OAD.

Monitoring Global Progress in Core Diabetes Control Metrics: Protocol for a Systematic Review of Prevalence (2015–2023)

Background The Global Diabetes Compact is a WHO-sponsored initiative that aims to improve diabetes care and prevention, and to reduce the global burden of diabetes. This includes the goal of monitoring the progress and achievement of country-level diabetes metrics and targets. The objective of this systematic review is to examine population-based studies from 2015–2023 to determine the status of core diabetes control metrics: glycaemic (HbA1c), blood pressure and lipid control (low-density lipoprotein and non-high-density lipoprotein cholesterol), and statin use. This review will describe regional and country-level variation in attainment gaps concerning these indicators. Methods This review will follow the JBI methodological approach to systematic reviews of prevalence, and will be reported using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. We will include population-based observational studies, conducted in all geographic settings that report data on adult populations (≥18 years) with diagnosed Type 1 or Type 2 diabetes, with no language restrictions. We will search the following databases: Ovid MEDLINE, Embase, Scopus, Cochrane Library, and WHO Global Index Medicus. Using Covidence, two reviewers will independently screen titles and abstracts against eligibility criteria, review potentially relevant full-text articles, and extract data from eligible studies. A third reviewer will resolve any conflicts. Reviewers will use a standardised data extraction form to extract study population, methodological, and outcome data. Primary outcomes are levels of glycaemic, blood pressure, and lipid control, and statin use. Methodological quality of included studies will be assessed using the JBI Critical Appraisal tool for studies reporting prevalence data. Extracted data will be synthesised using descriptive statistics and summarised narratively. Dissemination Findings will be used to inform global diabetes surveillance, prevention, and treatment initiatives. The completed review will be submitted for publication in a peer-reviewed journal, and presented at national and international conferences.

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

BackgroundThere is a high prevalence of mental illness in nursing home residents compared to older adults living in the community. This was highlighted in the most recent comprehensive systematic review on the topic, published in 2010. In the context of a rapidly aging population and increased numbers of older adults requiring residential care, this study aims to provide a contemporary account of the prevalence of mental illness among nursing home residents.MethodsThis protocol was prepared in line with the PRISMA-P 2015 Statement. Systematic searches will be undertaken across six electronic databases: PubMed, Embase, Web of Science, PsycNET, CINAHL, and s in Social Gerontology. Peer-reviewed studies published from 2009 onwards which report the prevalence of mental illness within nursing home populations will be included. Database searches will be supplemented by forward and backward citation searching. Titles and abstracts of records will be screened using a semi-automated process. The full text of selected records will be assessed to confirm inclusion criteria are met. Study selection will be recorded in a PRISMA flowchart. A pilot-tested form will be used to extract data from included studies, alongside the JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data. A study characteristics and results table will be prepared to present key details from each included study, supported by a narrative synthesis. Random-effects restricted maximum likelihood meta-analyses will be performed to compute pooled prevalence estimates for mental illnesses represented in the identified studies. Heterogeneity will be assessed using Cochran’s Q and Higgins’ I2 statistics. A Funnel plot and Egger’s test will be used to assess publication bias. The GRADE approach will be used to assess the quality of the body of evidence identified.DiscussionThe study will provide a comprehensive and contemporary account of the prevalence of mental illness among nursing home residents. Meta-analyses will provide robust prevalence estimates across a range of presentations. Key insights will be highlighted, including potential sources of heterogeneity. Implications for residents, researchers, care providers, and policymakers will be noted.Systematic review registrationPROSPERO: CRD42023456226.

Prevalence and incidence of cancer amongst adults with intellectual disability — a systematic review and meta-analysis protocol

Background People with intellectual disabilities have poorer health and die earlier than their peers without identified disabilities. This difference represents a significant inequality. Until recently, it was considered that cancer was less common in this population, mainly because they did not live long enough to develop age-related cancers. However, recent evidence has identified that people with intellectual disabilities may be at an increased risk of developing cancer but more likely to present for medical treatment at a later stage when cancer has spread. Nonetheless, the evidence is lacking and there is a need to understand the prevalence and incidence of cancer and subtypes of cancer in adults with intellectual disabilities. Methods A systematic review and meta-analysis will be undertaken to investigate the prevalence and incidence of cancer and subtypes of cancer in adults with an intellectual disability. The JBI Systematic reviews of prevalence and incidence and the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to develop this protocol. Electronic databases will be searched using predefined search terms to identify relevant studies using the Condition Context Population (CoCoPop) framework. Eligible studies should be observational and have published baseline data that have estimated or presented data on the prevalence or incidence of cancer in adults with intellectual disabilities. To assess the methodological quality of studies included in this review a modified version of the JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data will be used. Prevalence and incidence proportions will be analysed separately with individual study data being pooled using the DerSimonian-Laird proportion method and a random effects meta-analysis will be undertaken. Discussion This review will advance the epidemiological evidence to identify where targeted cancer care interventions are needed to help reduce the inequalities that this population experiences.

Systematic Review and Meta-Analysis of Global Neuroma Incidence in Upper Extremity Amputees.

Neuromas substantially decrease a patient's quality of life and obstruct the use of prosthetics. This systematic review and meta-analysis aimed to determine the global incidence of neuroma formation in upper extremity amputees. A literature search was performed using 3 databases: Web of Science, MEDLINE, and Cochrane. Inclusion criteria for the systematic review were those studies investigating only upper extremity amputees and reported postamputation neuroma. A random-effects, inverse-variance analysis was conducted to determine the pooled proportion of neuromas within the upper extremity amputation population. Critical appraisal using the JBI Checklist for Studies Reporting Prevalence Data of each individual article were performed for the systematic review. Eleven studies met the inclusion criteria collating a total of 1931 patients across 8 countries. More than three-fourth of patients are young men (77%; age range, 19-54 years) and had an amputation due to trauma. The random-effects analysis found the pooled combined proportion of neuromas to be 13% (95% confidence interval, 8%-18%). The treatment of neuroma is highly variable, with some patients receiving no treatment. The pooled proportion of neuroma incidence in the 1931 patients was 13%. With the known global prevalence of upper extremity amputees, this translates to nearly 3 million amputees suffering from a neuroma globally. Increasing training in preventative surgical methods could contribute to lowering this incidence and improving the outcomes of this patient population.

Epidemiology and clinical features of paroxysmal hemicrania: Asystematic review and meta-analysis.

To assess the prevalence or relative frequency of paroxysmal hemicrania and its clinical features in the adult general population and among adult patients evaluated for headache in tertiary care. Paroxysmal hemicrania is a rare trigeminal autonomic cephalalgia with characteristic attacks of headache, associated cranial autonomic symptoms and signs, and an absolute response to indomethacin. Its epidemiological burden remains unknown in both the adult general population and among adult patients evaluated for headache in a tertiary care setting. Moreover, the frequencies of the clinical features associated with paroxysmal hemicrania have not been well established. A literature search of PubMed and Embase was conducted from January 1, 1988, to January 20, 2023. Eligible for inclusion were observational studies reporting the point prevalence or relative frequency of paroxysmal hemicrania or its clinical features in the adult general population or among adult patients evaluated for headache in tertiary care. Two independent investigators (M.J.H. and J.G.L.) performed the title, abstract, and full-text article screening. Each included study's risk of bias was critically appraised using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. Estimates of prevalence or relative frequency were calculated using a random-effects meta-analysis. The between-study heterogeneity was assessed using the I2 statistic and further explored with meta-regression. This study was pre-registered on PROSPERO (identifier: CRD42023391127). A total of 17 clinic-based studies and one population-based study met the eligibility criteria. Importantly, an overall high risk of bias was observed across the eligible studies. The relative frequency of paroxysmal hemicrania was estimated to be 0.3% (95% CI, 0.2%-0.5%) among adult patients evaluated for headache in tertiary care with considerable heterogeneity (I2 = 76.4%). No cases with paroxysmal hemicrania were identified among 1,838 participants in a population-based sample. Moreover, the most prevalent cranial autonomic symptoms were lacrimation (77.3% [95% Cl, 62.7%-87.3%]), conjunctival injection (75.0% [95% Cl, 60.3%-85.6%]), and nasal congestion (47.7% [95% Cl, 33.6%-62.3%]). Our findings suggest that paroxysmal hemicrania is a rare disorder among adults evaluated for headache in tertiary care, while its prevalence in the general population remains unknown. Further studies focusing on the clinical features of paroxysmal hemicrania are warranted.

Psychiatric Morbidities After Stroke in Asia: A Systematic Review

Background: Stroke is currently the second leading cause of death worldwide and is one of the leading causes of long-term disability . Mood disorders are prevalent after a stroke and may hinder physical, functional, and cognitive recovery; hence, it is undeniably necessary to recognize them early. Stroke mortality is generally higher in Asia as most of the countries therein are in economic transition . Socioeconomic status is a major contributor to stroke burden as greater odds of disability are found in patients with lower educational status and income. Objectives: The primary objective of this study is to identify the psychiatric morbidities commonly seen after a stroke in Asia. Search Methods: The following databases were utilized for extensive literature search: PubMed (January 2002 to June 2022), Cochrane Library (January 2002 to June 2022), and EBSCO (January 2002 to June 2022). The search made use of keyword combinations, Boolean operators "AND" and "OR," truncations, and field tags last October 2022. Selection Criteria: Articles on the prevalence and cross-sectional studies were included if they involved stroke survivors who developed post-stroke psychiatric morbidities in Asia. Additional inclusion criteria consisted of studies that have to be written in the English language and having free full texts available. Data Collection and Analysis: This systematic review made use of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards and guidelines. The JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data was used in the assessment for the quality of articles to be included in this systematic review. Results and Conclusion: Affective disorders and generalized anxiety disorder were the common psychiatric morbidities identified post-stroke. The Hospital Anxiety and Depression Scale (HADS) may be used to diagnose post-stroke depression and anxiety. Males in their middle to late adulthood with higher National Institutes of Health Stroke Scale (NIHSS) scores and poor stroke outcomes (higher scores in the Modified Rankin Scale) were associated with a higher likelihood of developing the aforementioned psychiatric morbidities. Keywords: post-stroke, depression, anxiety, mania, psychosis, Asia

Prevalence of awake bruxism in the adult population: a systematic review and meta-analysis.

To evaluate the prevalence of awake bruxism (AB) in the adult population. Six main electronic databases and three sources of grey literature were searched to identify cross-sectional studies in which AB was assessed. The studies were independently selected by two reviewers in two phases, based on their eligibility criteria. The first one consisted of reading titles and abstracts, and the second one involved reading the full articles. The study quality assessment was obtained by using the "Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data", and the "R Statistics" software was used to perform meta-analyses. Seventeen out of 3086 identified studies were included. None of the studies scored high in methodological quality across all 9 items of the JBI checklist. However, "the use of valid methods to identify pathology" and "appropriate statistical analysis" were considered to have high methodological quality in all the studies. The overall pooled prevalence of the meta-analysis was 15.44% (99% confidence interval: 10.81 to 20.72%) and there was no difference for sex, sampling method and according to consensus-based classification. The prevalence of AB in adults was low. There was substantial methodological variability, which highlights the need for standardized guidelines. Prevalence data are useful for raising patients' and clinicians' awareness of the AB. Moreover, since AB can lead to possible pain and overload of the stomatognathic system, this knowledge can also guide dentists to achieve an early diagnosis of AB and to provide appropriate care management.

COVID-19 in hematopoietic stem-cell transplant recipients: A systematic review and meta-analysis of clinical characteristics and outcomes.

Patients who undergo hematopoietic stem-cell transplantation (HSCT) are more susceptible to developing severe forms of COVID-19 with an increased risk of mortality. The aim of this study was to analyze, by performing a systematic review and meta-analysis, all studies that evaluated COVID-19 in HSCT adult recipients and present clinical characteristics and outcomes. Studies were eligible for inclusion if they: (I) described the clinical characteristics of COVID-19 in adult (aged 18years old or above) HSCT recipients; (II) described outcomes of COVID-19 in this population, mainly lethality; (III) were full-text articles. We searched MedLine, Embase, SCOPUS, LILACS and Web of Science for full-text studies that evaluated COVID-19 in adult HSCT patients until 26 Apr 2023. Two independent reviewers screened the articles and extracted the data. The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Studies Reporting Prevalence Data was used to assess quality of the included studies. Meta-analysis was performed and the pooled prevalence of severe/critical disease and of death with a 95% CI was calculated with the random-effects model. Sixteen studies were included; seven (43.7%) were multicenter. Most of the studies were from Europe (37.5%). All of them had a low risk of bias using the JBI Checklist. A total of 1186 patients were included. Allogeneic HSCT patients were the majority in most studies, with a total of 861 patients (72.5%). The symptomatic rate was 79.4%. The pooled prevalence of severe/critical COVID-19 was 24.0% (95% CI 0.13-0.36; I2 =94%; n=334/990). The pooled prevalence of death for the entire population was 17% (95% CI 0.13-0.22; I2 =76%; n=221/1117), 17% (95% CI 0.12-0.23; I2 =67%; n=152/822) for allogeneic-HSCT and 14% (95% CI 0.08-0.22; I4 =65%; n=48/293) for autologous-HSCT. In conclusion, frequently the infection of SARS-CoV-2 in HSCT was symptomatic and lethality is higher than in general population. Thus, it is essential to focus on the implementation of measures to mitigate the risk of SARS-CoV-2 infection in this population, as well as to carefully assess HSCT recipients who develop COVID-19.

Epidemiology of insomnia disorder in older persons according to the Diagnostic and Statistical Manual of Mental Disorders: a systematic review and meta-analysis.

There is a scarcity of summarizing data on the epidemiology of insomnia in older persons, especially when diagnosed with international criteria. This study aimed to estimate the prevalence and correlates of insomnia disorder in older persons, according to the Diagnostic and Statistical Manual of Mental Disorders (DSM). Through PubMed/MEDLINE, EMBASE, and Web of Science (WoS), we searched for relevant articles published before June 28, 2023. The risk of bias was weighed using the Joanna Briggs Institute's (JBI's) critical appraisal checklist for studies reporting prevalence data. For our analyses, we used a random-effect model, with subgroup analyses, meta-regression, and sensitivity analyses to explore potential sources of heterogeneity. We followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement. We included 18,270 participants across 16 studies. The male/female ratio was 0.89 (12 studies), and the mean age varied from 65.9 to 83.1years (8 studies). The pooled prevalence of insomnia was 19.6% (95% CI = [12.3%; 28.3%]), with substantial heterogeneity. This prevalence fluctuated according to the sample size, the minimal age for inclusion, and the study quality, considering that the risk of bias was moderate for most of studies. There was a publication bias, with a very low level of certainty. Insomnia disorder was associated with the female gender, depression, anxiety, and somatic illnesses notably cardiovascular, respiratory, and painful ones. Nearly one in every five old individuals was considered to have insomnia disorder, which was associated with the gender and the existence of mental health and/or somatic conditions. We registered the protocol in the International Prospective Register of Systematic Reviews (PROSPERO) with registration number: CRD42022344675.

Prevalence and incidence of cancer amongst adults with intellectual disability — a systematic review and meta-analysis protocol

Background: People with intellectual disabilities have poorer health and die earlier than their peers without identified disabilities. This difference represents a significant inequality. Until recently, it was considered that cancer was less common in this population, mainly because they did not live long enough to develop age-related cancers. However, recent evidence has identified that people with intellectual disabilities may be at an increased risk of developing cancer but more likely to present for medical treatment at a later stage when cancer has spread. Nonetheless, the evidence is lacking and there is a need to understand the prevalence and incidence of cancer and subtypes of cancer in adults with intellectual disabilities. Methods A systematic review and meta-analysis will be undertaken to investigate the prevalence and incidence of cancer and subtypes of cancer in adults with an intellectual disability. The JBI Systematic reviews of prevalence and incidence and the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to develop this protocol. Electronic databases will be searched using predefined search terms to identify relevant studies using the Condition Context Population (CoCoPop) framework. Eligible studies should be observational and have published baseline data that have estimated or presented data on the prevalence or incidence of cancer in adults with intellectual disability. To assess the methodological quality of studies included in this review a modified version of the JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data will be used. Prevalence and incidence proportions will be analysed separately with individual study data being pooled using the DerSimonian-Laird proportion method and a random effects meta-analysis will be undertaken. Discussion: This review will advance the epidemiological evidence to identify where targeted cancer care interventions are needed to help reduce the inequalities that this population experiences.

Prevalence of ictal injuries in functional (psychogenic nonepileptic) seizures: A systematic review and meta-analysis.

Ictal injuries have long been considered typical signs of epileptic seizures. However, studies have shown that patients with functional seizures (FS)-also named psychogenic nonepileptic seizures-can also present these signs, misleading physicians and delaying a correct diagnosis. This systematic review aimed to assess the prevalence of injuries from FS. A literature search was performed in PubMed, Embase, LILACS (Latin American and Caribbean Health Sciences Literature), Scopus, Web of Science, PsycINFO, Google Scholar, OpenGrey, and ProQuest. Observational studies were included. The risk of bias was assessed using the Joanna Briggs Institute (JBI) checklist for studies reporting prevalence data. RStudio was used for meta-analyses. Cumulative evidence was evaluated according to Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria. From the 2607 identified records, 41 studies were included in the qualitative synthesis, and 28 were included in meta-analyses. A meta-analysis of 13 studies, including 1673 individuals, resulted in an overall lifetime prevalence of injuries due to FS per person of 25% (95% confidence interval [CI] = 19%-32%, I2 = 88%). Considering a limited period (video-electroencephalographic [VEEG] monitoring days), a meta-analysis of 13 studies, including 848 individuals, resulted in an injury prevalence due to FS per person of .7% (95% CI = 0%-3%, I2 = 73%). Also, a meta-analysis of eight studies, including 1000 individuals, resulted in a prevalence of injuries per FS of .1% (95% CI = 0%-.98%, I2 = 49%). The certainty in cumulative evidence assessed by GRADE was rated "very low" for lifetime prevalence of injuries per person, "low" for prevalence per person during VEEG monitoring, and "moderate" for prevalence per number of FS. Overall pooled lifetime prevalence of injuries due to FS per person was 25%. In comparison, the prevalence of injuries per person during VEEG monitoring and per functional seizure was .7% and .1%, respectively. [Correction added on 07 October 2023, after first online publication: In the preceding sentence, 'consecutively' was corrected to 'respectively'.] The evidence of the occurrence of injuries due to FS breaks the paradigm that epileptic seizures can cause injuries but FS cannot.
