Abstract Background Arsenic is a toxic metalloid element frequently found in the environment. Chronic arsenic exposure is a critical public health issue in many countries since the identification of arsenic and its compounds as human carcinogens by the World Health Organization. After absorption, inorganic arsenic (iAs) is mainly methylated into monomethylated and dimethylated compounds (MMA, DMA), which are then excreted through the kidney together with unmethylated iAs. Whether the methylation process is to detoxify or potentiate arsenic toxicity, however, remains an ongoing debate. The purpose of this systematic review was to conduct a comprehensive meta-analysis to estimate the association between arsenic exposure and urothelial cancer. Methods 10 observational studies met the inclusion criteria and were included in the systematic review. IAs%, MMA% and DMA% were extracted from each paper. Weighted Mean Differences with 95% confidence intervals were defined according to Cases minus Controls. Pooled risk estimates from individual studies were assessed using random effects models. Meta-regression analysis was performed to estimate the extent of urothelial cancer risk as a function of iAs%, MMA% and DMA%. Results Results showed as patients with urothelial cancer presented higher level of urinary iAs% (WMD 2.70, 95%CI 0.64-4.76), MMA% (WMD 2.81, 95%CI 1.43-4.20) and DMA% (WMD-3.44, 95%CI-6.57–0.30). Conclusions These findings suggest that higher level of iAs% and MMA% and lower level of DMA% were associated with an increased risk of urothelial cancer. Additional population based studies are needed to understand the role of arsenic in cancer development. Understanding the meaning of arsenic metabolism could improve the risk assessment of arsenic toxicity and provide a potential tool for disease prediction and prevention. Key messages Higher level of iAs%, MMA% and DMA% were associated with an increased risk of urothelial cancer. Understanding the meaning of arsenic metabolism could improve the risk assessment of arsenic toxicity.

Background: Arsenic is a toxic metalloid element widely distributed throughout the environment. Arsenic contaminated water has become an ongoing public health issue affecting hundred million people worldwide. The aim of this paper was to summarize the evidence in the association between arsenic metabolites and urinary tract cancer risk. Methods: A systematic review was conducted searching for observational studies that evaluated the association of arsenic metabolites and urinary tract cancer. Risk estimates from individual studies were pooled by using random effects models. Results: All the metabolites considered in this study resulted to be significantly associated to urothelial cancer, respectively: IA% 3.51 (1.21–5.82) (p = 0.003), MMA with WMD = 2.77 (1.67–3.87) (p < 0.001) and DMA with WMD = −4.56 (−7.91–1.22) (p = 0.008). Conclusions: Arsenic metabolites are significantly associated to urothelial cancer. Future studies will help to verify the independent association(s) between arsenic metabolites and urothelial cancer.

BackgroundHarmful alcohol use leads to a large burden of disease and disability which disportionately impacts LMICs. The World Health Organization and the Lancet have issued calls for this burden to be addressed, but issues remain, primarily due to gaps in information. While a variety of interventions have been shown to be effective at reducing alcohol use in HICs, their efficacy in LMICs have yet to be assessed. This systematic review describes the current published literature on alcohol interventions in LMICs and conducts a meta analysis of clinical trials evaluating interventions to reduce alcohol use and harms in LMICs.MethodsIn accordance with PRISMA guidelines we searched the electronic databases Pubmed, EMBASE, Scopus,Web of Science, Cochrane, and Psych Info. Articles were eligible if they evaluated an intervention targeting alcohol-related harm in LMICs. After a reference and citation analysis, we conducted a quality assessment per PRISMA protocol. A meta-analysis was performed on the 39 randomized controlled trials that evaluated an alcohol-related outcome.ResultsOf the 3,801 articles from the literature search, 87 articles from 25 LMICs fit the eligibility and inclusion criteria. Of these studies, 39 randomized controlled trials were included in the meta-analysis. Nine of these studies focused specifically on medication, while the others focused on brief motivational intervention, brain stimulation, AUDIT-based brief interventions, WHO ASSIST-based interventions, group based education, basic screening and interventions, brief psychological or counseling, dyadic relapse prevention, group counseling, CBT, motivational + PTSD based interview, and health promotion/awareness. Conclusion Issues in determining feasible options specific to LMICs arise from unstandardized interventions, unequal geographic distribution of intervention implementation, and uncertain effectiveness over time. Current research shows that brain stimulation, psychotherapy, and brief motivational interviews have the potential to be effective in LMIC settings, but further feasibility testing and efforts to standardize results are necessary to accurately assess their effectiveness.

Aims To investigate the association between TBI and stroke risk. Summary of review We undertook a systematic review of MEDLINE, EMBASE, CINAHL, and The Cochrane Library from inception to 4th December 2020. We used random-effects meta-analysis to pool hazard ratios (HR) for studies which reported stroke risk post-TBI compared to controls. Searches identified 10,501 records; 58 full texts were assessed for eligibility and 18 met the inclusion criteria. The review included a large sample size of 2,606,379 participants from four countries. Six studies included a non-TBI control group, all found TBI patients had significantly increased risk of stroke compared to controls (pooled HR 1.86; 95% CI 1.46-2.37). Findings suggest stroke risk may be highest in the first four months post-TBI, but remains significant up to five years post-TBI. TBI appears to be associated with increased stroke risk regardless of severity or subtype of TBI. There was some evidence to suggest an association between reduced stroke risk post-TBI and Vitamin K antagonists and statins, but increased stroke risk with certain classes of antidepressants. Conclusion TBI is an independent risk factor for stroke, regardless of TBI severity or type. Post-TBI review and management of risk factors for stroke may be warranted.

IntroductionPrisons are places with high vulnerability and high risk for the development of sexually transmitted infections. World Health Agencies recommend establishing intervention measures, such as information and education, on the prevention of diseases. Thus, technologies as tools for health education have been used to reduce sexually transmitted infections. However, no systematic review has investigated the effectiveness of these interventions. Therefore, this review’s objective is to examine the effect of educational technologies used for preventing sexually transmitted infections in incarcerated women.Methods and analysisPreferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines will be strictly followed. The following electronic databases will be searched: Scopus; Cumulative Index of Nursing and Allied Health, Education Resources Information Center, Embase, PsycINFO, PubMed/Medline, Web of Science and Google Scholar. Randomised clinical trials of interventions that used educational technologies to prevent sexually transmitted infections in incarcerated women will be searched in the databases from the beginning of 2020 until December by two researchers independently. A narrative synthesis will be constructed for all included studies, and if there are sufficient data, a meta-analysis will be performed using the Review Manager software (V.5.3). Continuous results will be presented as the weighted mean difference or the standardised mean difference with 95% CIs. Under the heterogeneity of the included studies, a random-effects or fixed-effects model will be used. The studies’ heterogeneity will be assessed by the I2 method. The sensitivity analysis will be carried out to examine the magnitude of each study’s influence on the general results. A significance level of p≤0.05 will be adopted.Ethics and disclosureEthical approval is not required because no primary data will be collected. The results will be published in journals reviewed by peers.PROSPERO registration numberCRD42020163820.

Animal Milk

IntroductionPrevalence rates of breastfeeding remain low even though the World Health Organization (WHO) and the American Academy of Pediatrics recommend exclusive breast feeding for the first 6 months of life in combination with appropriate complementary feeding beyond six 6 months of age. There have been several studies that address the implication of drinking animal milk and/or infant formula on children’s health and development when breast feeding is not offered during the first year of life. Vast improvements have been made in infant formula design, which may increase its benefits compared with animal’s milk. The objective of this review is therefore to synthesise the most recent evidence on the effects of the consumption of animal milk compared with infant formula in non-breastfed or mixed breastfed infants aged 6–11 months.Methods and analysisWe will conduct a systematic review and meta-analysis of studies that assessed the effect of animal milk compared with formula or mixed-fed (breastmilk and formula) on infants aged 6–11 months. The primary outcomes of interest include anaemia, gastrointestinal blood loss, weight for age, height for age and weight for height. We will include randomised and non-randomised studies with a control group. We will use the Cochrane risk of bias tools to assess the risk of bias. We will use meta-analysis to pool findings if the identified studies are conceptually homogenous and data are available from more than one study. We will assess the overall quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach.Ethics and disseminationThis is a systematic review, so no patients will be directly involved in the design or development of this study. The findings from this systematic review will be disseminated to relevant patient populations and caregivers and will guide the WHO’s recommendations on formula consumption versus animal milk in infants aged 6–11 months.Trial registration numberCRD42020210925.

Abstract Objectives Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial disease with limited therapeutic options. The measurement of Krebs von den Lungen-6 (KL-6) glycoprotein has been proposed for evaluating the risk of IPF progression and predicting patient prognosis, but the robustness of available evidence is unclear. Methods We searched Medline and Embase databases for peer-reviewed literature from inception to April 2020. Original articles investigating KL-6 as prognostic marker for IPF were retrieved. Considered outcomes were the risk of developing acute exacerbation (AE) and patient survival. Meta-analysis of selected studies was conducted, and quantitative data were uniformed as odds ratio (OR) or hazard ratio (HR) estimates, with corresponding 95% confidence intervals (CI). Results Twenty-six studies were included in the systematic review and 14 were finally meta-analysed. For AE development, the pooled OR (seven studies) for KL-6 was 2.72 (CI 1.22–6.06; p=0.015). However, a high degree of heterogeneity (I2=85.6%) was found among selected studies. Using data from three studies reporting binary data, a pooled sensitivity of 72% (CI 60–82%) and a specificity of 60% (CI 52–68%) were found for KL-6 measurement in detecting insurgence of AE in IPF patients. Pooled HR (seven studies) for mortality prediction was 1.009 (CI 0.983–1.036; p=0.505). Conclusions Although our meta-analysis suggested that IPF patients with increased KL-6 concentrations had a significant increased risk of developing AE, the detection power of the evaluated biomarker is limited. Furthermore, no relationship between biomarker concentrations and mortality was found. Caution is also needed when extending obtained results to non-Asian populations.

AbstractThe aims of this systematic review and meta-analysis were to describe prevalence of cardiovascular disease in gout, compare these results with non-gout controls and consider whether there were differences according to geography. PubMed, Scopus and Web of Science were systematically searched for studies reporting prevalence of any cardiovascular disease in a gout population. Studies with non-representative sampling, where a cohort had been used in another study, small sample size (< 100) and where gout could not be distinguished from other rheumatic conditions were excluded, as were reviews, editorials and comments. Where possible meta-analysis was performed using random-effect models. Twenty-six studies comprising 949,773 gout patients were included in the review. Pooled prevalence estimates were calculated for five cardiovascular diseases: myocardial infarction (2.8%; 95% confidence interval (CI)s 1.6, 5.0), heart failure (8.7%; 95% CI 2.9, 23.8), venous thromboembolism (2.1%; 95% CI 1.2, 3.4), cerebrovascular accident (4.3%; 95% CI 1.8, 9.7) and hypertension (63.9%; 95% CI 24.5, 90.6). Sixteen studies reported comparisons with non-gout controls, illustrating an increased risk in the gout group across all cardiovascular diseases. There were no identifiable reliable patterns when analysing the results by country. Cardiovascular diseases are more prevalent in patients with gout and should prompt vigilance from clinicians to the need to assess and stratify cardiovascular risk. Future research is needed to investigate the link between gout, hyperuricaemia and increased cardiovascular risk and also to establish a more thorough picture of prevalence for less common cardiovascular diseases.
