Background: Low vitamin D (vit D) serum levels have been linked to various diseases such as multiple sclerosis, cardiovascular diseases, and diabetes. Maintenance of optimal vit D level should be supported by foods and supplements. Limited food sources of vit D made researchers focus on food fortification in recent years. Methods: A systematic review of randomized controlled trials reporting the impact of vit D food fortification on 25-hydroxy vitamin D [25(OH)D] level was conducted on PubMed, Scopus, ISI Web of Science and Google Scholar from inception up to August 2017. Results: Sixteen studies met the inclusion criteria and most of them (n =14) have represented the significant effect of food fortification on the improvement of vit D status of the participants. However, two studies failed to find any reasonable associations. Furthermore, it was observed that vit D food fortification has a greater impact on the people with lower 25(OH)D serum levels. Conclusions: Fortification of foods with vit D has a significant impact on serum 25(OH)D concentrations. Therefore, food enrichment is an economical and effective approach for different populations to prevent vit D deficiency.

Abstract Background Intimate partner violence (IPV) is a population health problem linked to a myriad of negative psychological, physical, emotional, sexual and reproductive health outcomes for women. The movement towards working with boys and men over the past couple of decades has increased the number of interventions specifically directed at men who perpetrate violence against a female partner. There is little evidence-based research on key characteristics of effective interventions directed at men to reduce or prevent IPV against female partners. The objective of this systematic review is to identify interventions specifically directed at males , as the perpetrators of violence against women, that have proven to be effective in preventing or reducing intimate partner violence. Methods The following electronic databases will be used to search for peer-reviewed studies: MEDLINE (OVID), Embase (OVID), PsycInfo (OVID), CINAHL (EBSCO), Global Health (EBSCO), Gender Watch (ProQuest), Web of Science (Web of Knowledge), PROSPERO, Cochrane Central Register of Controlled Trials Database (Ovid) and SCOPUS. We will include randomized control trials, non-randomized studies of interventions published in peer-reviewed journals and relevant unpublished manuscripts, books/chapters and clinical or programme study reports. Studies have to demonstrate direction of effect (i.e. pre-post intervention/difference between groups) in terms of prevention or reduction in the outlined outcomes. Primary outcomes include change in behaviour and knowledge of male perpetrator regarding the impact of IPV on women as well as women’s experience of IPV. Secondary outcomes include change in behaviours around substance use and social activities, decrease in negative mental health outcomes and interactions with law enforcement. Studies will be screened, appraised and extracted by two reviewers; any conflicts will be resolved through discussion. Narrative synthesis will be used to analyse and present findings. If sufficient and comparable data is available, a meta-analysis will be conducted. Discussion This review will provide synthesized evidence on interventions directed at males to reduce or prevent their perpetration of intimate partner violence against female partners. Implications for practice will include key characteristics of interventions proven to be effective based on evidence synthesis and certainty of findings. Recommendations for further research will also be considered. Systematic review registration This protocol was submitted for registration in the International Prospective Register of Systematic Reviews (PROSPERO) on September 4, 2020.

IntroductionCombinations of unhealthy lifestyle factors are strongly associated with mortality, cardiovascular disease (CVD) and cancer. It is unclear how socioeconomic status (SES) affects those associations. Lower SES groups may be disproportionately vulnerable to the effects of unhealthy lifestyle factors compared with higher SES groups via interactions with other factors associated with low SES (eg, stress) or via accelerated biological ageing. This systematic review aims to synthesise studies that examine how SES moderates the association between lifestyle factor combinations and adverse health outcomes. Greater understanding of how lifestyle risk varies across socioeconomic spectra could reduce adverse health by (1) identifying novel high-risk groups or targets for future interventions and (2) informing research, policy and interventions that aim to support healthy lifestyles in socioeconomically deprived communities.Methods and analysisThree databases will be searched (PubMed, EMBASE, CINAHL) from inception to March 2020. Reference lists, citations and grey literature will also be searched. Inclusion criteria are: (1) prospective cohort studies; (2) investigations of two key exposures: (a) lifestyle factor combinations of at least three lifestyle factors (eg, smoking, physical activity and diet) and (b) SES (eg, income, education or poverty index); (3) an assessment of the impact of SES on the association between combinations of unhealthy lifestyle factors and health outcomes; (4) at least one outcome from—mortality (all cause, CVD and cancer), CVD or cancer incidence. Two independent reviewers will screen titles, abstracts and full texts of included studies. Data extraction will focus on cohort characteristics, exposures, direction and magnitude of SES effects, methods and quality (via Newcastle-Ottawa Scale). If appropriate, a meta-analysis, pooling the effects of SES, will be performed. Alternatively, a synthesis without meta-analysis will be conducted.Ethics and disseminationEthical approval is not required. Results will be disseminated via peer-reviewed publication, professional networks, social media and conference presentations.PROSPERO registration numberCRD42020172588.

IntroductionForgetting to take a medication is the most common reason for non-adherence to self-administered medication. Dose administration aids (DAAs) are a simple and common solution to improve unintentional non-adherence for oral tablets. DAAs can be in the form of compartmentalised pill boxes, automated medication dispensing devices, blister packs and sachets packets. This protocol aims to outline the methods that will be used in a systematic review of the current literature to assess the impact of DAAs on adherence to medications and health outcomes.Methods and analysisRandomised controlled trials will be identified through electronic searches in databases including EMBASE, MEDLINE, CINAHL and the Cochrane Library, from the beginning of each database until January 2020. Two reviewers will independently screen studies and extract data using the standardised forms. Data extracted will include general study information, characteristics of the study, participant characteristics, intervention characteristics and outcomes. Primary outcome is to assess the effects of DAAs on medication adherence. Secondary outcome is to evaluate the changes in health outcomes. The risk of bias will be ascertained by two reviewers in parallel using The Cochrane Risk of Bias Tool. A meta-analysis will be performed if data are homogenous.Ethics and disseminationEthics approval will not be required for this study. The results of the review described within this protocol will be disseminated through publication in a peer-reviewed journal and relevant conference presentations.PROSPERO registration numberCRD42018096087

BACKGROUNDMortality associated with infections caused by carbapenem-resistantEnterobacteriaceae(CRE) is higher than mortality due to carbapenem-sensitive pathogens.OBJECTIVETo examine the association between mortality from bacteremia caused by carbapenem-resistant (CRKP) and carbapenem-sensitiveKlebsiella pneumoniae(CSKP) and to assess the impact of appropriate initial antibiotic therapy (IAT) on mortality.DESIGNSystematic review and meta-analysisMETHODSWe searched MEDLINE, EMBASE, CINAHL, and Wiley Cochrane databases through August 31, 2016, for observational studies reporting mortality among adult patients with CRKP and CSKP bacteremia. Search terms were related toKlebsiella, carbapenem-resistance, and infection. Studies including fewer than 10 patients per group were excluded. A random-effects model and meta-regression were used to assess the relationship between carbapenem-resistance, appropriateness of IAT, and mortality.RESULTSMortality was higher in patients who had CRKP bacteremia than in patients with CSKP bacteremia (15 studies; 1,019 CRKP and 1,148 CSKP patients; unadjusted odds ratio [OR], 2.2; 95% confidence interval [CI], 1.8–2.6; I2=0). Mortality was lower in patients with appropriate IAT than in those without appropriate IAT (7 studies; 658 patients; unadjusted OR, 0.5; 95% CI, 0.3–0.8; I2=36%). CRKP patients (11 studies; 1,326 patients; 8-year period) were consistently less likely to receive appropriate IAT (unadjusted OR, 0.5; 95% CI, 0.3–0.7; I2=43%). Our meta-regression analysis identified a significant association between the difference in appropriate IAT and mortality (OR per 10% difference in IAT, 1.3; 95% CI, 1.0–1.6).CONCLUSIONSAppropriateness of IAT is an important contributor to the observed difference in mortality between patients with CRKP bacteremia and patients with CSKP bacteremia.Infect Control Hosp Epidemiol2017;38:1319–1328
