Colorectal cancer (CRC) is a common cancer with a huge impact on international public health. This review discusses recent evidence on modifiable and non-modifiable risk factors for CRC using a systematic review method. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines on systematic reviews and meta-analyses of observational studies. The literature search was performed on the Ovid MEDLINE database and included publications from 2015 to 2017, followed by a quality assessment and a narrative synthesis. Of the 90 identified articles, there were 13 meta-analyses with statistically significant results. Seven articles discussed modifiable risk factors and six articles discussed non-modifiable risk. The modifiable risk factors with the highest risk were radiotherapy of prostate cancer (pooled odds ratio 1.68; 95% confidence interval [CI] 1.33–2.12). The non-modifiable risk factors with the highest risk was Lynch syndrome (hazard ratio 135.49; 95% CI 111.55–164.57). This review discovered new and previously known risk factors for CRC. Recent evidence shows that research on CRC risk factors is continuing to grow indicating that more studies on risk factors are needed to optimize CRC prevention and early detection.

BackgroundInterpersonal violence is a leading cause of morbidity and mortality. The strength and population effect of modifiable risk factors for interpersonal violence, and the quality of the research evidence is not known.AimsWe aimed to examine the strength and population effect of modifiable risk factors for interpersonal violence, and the quality and reproducibility of the research evidence.MethodWe conducted an umbrella review of systematic reviews and meta-analyses of risk factors for interpersonal violence. A systematic search was conducted to identify systematic reviews and meta-analyses in general population samples. Effect sizes were extracted, converted into odds ratios and synthesised, and population attributable risk fractions (PAF) were calculated. Quality analyses were performed, including of small study effects, adjustment for confounders and heterogeneity. Secondary analyses for aggression, intimate partner violence and homicide were conducted, and systematic reviews (without meta-analyses) were summarised.ResultsWe identified 22 meta-analyses reporting on risk factors for interpersonal violence. Neuropsychiatric disorders were among the strongest in relative and absolute terms. The neuropsychiatric risk factor that had the largest effect at a population level were substance use disorders, with a PAF of 14.8% (95% CI 9.0–21.6%), and the most important historical factor was witnessing or being a victim of violence in childhood (PAF = 12.2%, 95% CI 6.5–17.4%). There was evidence of small study effects and large heterogeneity.ConclusionsNational strategies for the prevention of interpersonal violence may need to review policies concerning the identification and treatment of modifiable risk factors.Declarations of interestJ.R.G. is an NIHR Senior Investigator.

IntroductionAtrial fibrillation (AF) is a common arrhythmia in the critical care environment. New-onset AF is associated with increased mortality and intensive care unit (ICU) length of stay. Observational studies have identified several epidemiological and disease severity-related factors associated with developing new-onset AF on the ICU. However, there are limited data on the modifiable risk factors in the general adult ICU population.We describe a protocol for a systematic review of modifiable and non-modifiable risk factors for new-onset AF in the general adult ICU population. The results of this review will aid the development of risk prediction tools and inform future research into AF prevention on the ICU.Methods and analysisMedical Literature Analysis and Retrieval System Online, Excerpta Medica database and the Cochrane Library, including Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials will be searched for studies that assess the association of patient variables, investigation results, interventions and diagnoses associated with subsequent new-onset AF on the ICU.Only studies involving adult patients admitted to non-service-specific ICUs will be included. We will extract data relating to the statistical association between reversible and non-reversible factors and AF, the quality of the studies and the generalisability of the results. This systematic review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.Ethics and disseminationThis proposed systematic review will be based on published data, and therefore ethical approval is not required. The findings of this study will be disseminated through publication in a peer reviewed journal and will be presented at conferences.PROSPERO registration numberCRD42017074221.

Introduction: Metabolic syndrome as one of the risk factors for cardiovascular diseases has recently been the focus of clinical studies. This study was conducted to determine the prevalence of metabolic syndrome in hemodialysis patients in Iran. Methods: The present systematic review was done using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Case-control, cohort and crosssectional studies conducted in Iran were included. Clinical trials, case reports, letters to editors, systematic reviews, study protocols, narrative reviews, and case series were excluded. Subgroup analysis was conducted for determining the heterogeneity based on the participants as well as their gender. Meta-analysis was conducted using STATA version 14.0. Results: The prevalence of metabolic syndrome among 799 patients was 50% (95% CI: 47.0, 53.0, I2=50.6). The analysis of subgroups was conducted for determining the heterogeneity based on the participants as well as their gender. Based on the analysis of the subgroups using a random effects model, the prevalence of metabolic syndrome was found to be 44% and 55% in Iranian men and women undergoing hemodialysis, respectively. Conclusion: Given the high prevalence of metabolic syndrome in hemodialysis patients, it is advisable and logical that patients with chronic renal failure should be regularly evaluated for metabolic syndrome and cardiovascular risk factors both at the diagnosis time and afterwards.

ObjectivesTo assess the communicative quality of colorectal cancer patient decision aids (DAs) about treatment options, the current systematic review was conducted.DesignSystematic review.Data sourcesDAs (published between 2006 and 2019) were identified through academic literature (MEDLINE, Embase, CINAHL, Cochrane Library and PsycINFO) and online sources.Eligibility criteriaDAs were only included if they supported the decision-making process of patients with colon, rectal or colorectal cancer in stages I–III.Data extraction and synthesisAfter the search strategy was adapted from similar systematic reviews and checked by a colorectal cancer surgeon, two independent reviewers screened and selected the articles. After initial screening, disagreements were resolved with a third reviewer. The review was conducted in concordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. DAs were assessed using the International Patient Decision Aid Standards (IPDAS) and Communicative Aspects (CA) checklist.ResultsIn total, 18 DAs were selected. Both the IPDAS and CA checklist revealed that there was a lot of variation in the (communicative) quality of DAs. The findings highlight that (1) personalisation of treatment information in DAs is lacking, (2) outcome probability information is mostly communicated verbally and (3) information in DAs is generally biased towards a specific treatment. Additionally, (4) DAs about colorectal cancer are lengthy and (5) many DAs are not written in plain language.ConclusionsBoth instruments (IPDAS and CA) revealed great variation in the (communicative) quality of colorectal cancer DAs. Developers of patient DAs should focus on personalisation techniques and could use both the IPDAS and CA checklist in the developmental process to ensure personalised health communication and facilitate shared decision making in clinical practice.

IntroductionChildren are one of the most vulnerable groups in disasters. Improving students’ knowledge and skills to prepare for disasters can play a major role in children’s health. School as a place to teach children can make a significant contribution to provide the necessary skills. This study aims to identify the effects, strengths and weaknesses of interventions in schools to prepare children for disasters.Methods and analysisWe use Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to develop a protocol for this systematic review. The included studies will report on the results of interventions targeting ‘schoolchildren’ defined as individuals between 4 and under 18 years old studying in schools. Different electronic databases will be used for a comprehensive literature search, including MEDLINE, Web of Science, CINAHL, PsycINFO, Cochrane Register of Controlled Trials and EMBASE to identify the records that match the mentioned inclusion criteria published till December 2020. The main search terms are ‘disaster’, ‘preparedness’, ‘children’ and ‘school’. Four types of data will be extracted from the qualified studies including study characteristics (study design, year of publication and geographical region where the study was conducted), participant characteristics (sample size, age and gender), intervention characteristics (aim of intervention, intervention facilitators and barriers) and intervention outcomes. The quality appraisal of the selected papers will be conducted using Cochrane Collaboration’s Risk of Bias for quantitative studies and Critical Appraisal Skills Programme checklist for qualitative studies. We use a narrative synthesis for this systematic review. The narrative synthesis refers to an approach to systematic reviews which focuses mostly on applying words and texts to summarise and explain findings.Ethics and disseminationThis paper is a part of a Ph.D. thesis of Hamed Seddighi at University of Social welfare and Rehabilitation Sciences with ethics code IR.USWR.REC.1399.008 approved by the Ethics Committee of the above-mentioned university.PROSPERO registration numberCRD42020146536.
