“…The tool provides reviews of a general level of high, medium, or low quality based on a score that has a maximum of 11 points. Studies scoring between 9 and 11 were considered high quality, studies scoring between 6 and 8 were considered medium quality, and studies scoring between 0 and 5 were regarded as low quality ( 13 ).…”

Background: In humanitarian crises, water, sanitation and hygiene interventions are critical for the survival of people. However, strong evidence-based information is still limited. In order to describe the quantity and quality of current evidence, we conducted an evidence gap map provides a visual overview, highlighting areas lacking evidence. Methods: According to developed inclusion and exclusion criteria, a systematic literature search was conducted to find related systematic reviews and meta-analyses. The databases, including PubMed, Web of Science, SCOPUS and Cochrane were searched using search strings from 2000 until 2021. Characteristics of the included reviews were extracted and summarized. Two persons evaluated methodological quality independently using the AMSTAR tool. Invite a third person to solve any discrepancies. Results: This study revealed seven systematic reviews, including one meta-analysis. One study was of high quality, four of medium, and two of low quality. A total of 272 primary studies were included with a median value of 38.8 (range, 6-106) which deeply analyzed for data extraction. Cross-sectional, case-control, and qualitative case studies were the most used study designs. Diarrheal diseases were the most reported outcomes representing 46% of the impact evaluations. Cholera outbreaks account for 43% of a crisis context. The research gaps were insufficient reporting of some interventions with related outcomes and the geographical distribution of current evidence. Conclusion: There is a limitation in current evidence represented by a lack of high-quality and experimental studies investigate the impact of water, sanitation and hygiene (WaSH) interventions on health and behavioral outcomes in humanitarian sittings.

“…We searched ClinicalTrials.gov for ongoing FMT trials and conducted an umbrella review following Cochrane living review guidelines (Elliott et al, 2017;Hunt et al, 2018). An umbrella review provides an overview of evidence from systematic reviews and metaanalyses; a living review is continually updated (Aromataris et al, 2015;Neuenschwander et al, 2019;Zhang et al, 2020). As FMT develops, new evidence could emerge affecting findings, so we will update our review.…”

BackgroundGut microbiome dysbiosis has been implicated in various gastrointestinal and extra-gastrointestinal diseases, but evidence on the efficacy and safety of fecal microbiota transplantation (FMT) for therapeutic indications remains unclear.MethodsThe gutMDisorder database was used to summarize the associations between gut microbiome dysbiosis and diseases. We performed an umbrella review of published meta-analyses to determine the evidence synthesis on the efficacy and safety of FMT in treating various diseases. Our study was registered in PROSPERO (CRD42022301226).ResultsGut microbiome dysbiosis was associated with 117 gastrointestinal and extra-gastrointestinal. Colorectal cancer was associated with 92 dysbiosis. Dysbiosis involving Firmicutes (phylum) was associated with 34 diseases. We identified 62 published meta-analyses of FMT. FMT was found to be effective for 13 diseases, with a 95.56% cure rate (95% CI: 93.88–97.05%) for recurrent Chloridoids difficile infection (rCDI). Evidence was high quality for rCDI and moderate to high quality for ulcerative colitis and Crohn’s disease but low to very low quality for other diseases.ConclusionGut microbiome dysbiosis may be implicated in numerous diseases. Substantial evidence suggests FMT improves clinical outcomes for certain indications, but evidence quality varies greatly depending on the specific indication, route of administration, frequency of instillation, fecal preparation, and donor type. This variability should inform clinical, policy, and implementation decisions regarding FMT.

“…But the evidence was often conflicting, complicating the making of dietary recommendations. (Zhang et al, 2020) Further, most of the studies investigating the risks of egg consumption are conducted in middle and high-income countries. Below we summarize the risks of egg consumption that might be relevant for LMICs.…”

Eggs like other animal-source foods (ASFs), contain an array of macro and micronutrients that promote physical and cognitive growth, nutrition, and health outcomes. Hence, they can be used to reduce rampant undernutrition in low-and middle-income countries (LMICs). Yet consumption of eggs remains low in such countries for various reasons. Given their potential as a tool for reducing malnutrition, this paper reviews the literature on the benefits, risks, and barriers to egg consumption in LMICs. Research indicates that egg consumption is associated with several nutritional and health benefits in newborns, young children, and pregnant and lactating women, but few studies on other groups exist. Effects of egg consumption on diet-related chronic diseases seem to be inconclusive, and early introduction of eggs to infants has reduced allergy risk of eggs later in life in several studies. Some main barriers to egg consumption in LMIC include unaffordability and unavailability, partly due to low poultry productivity, high poultry feed prices, cultural beliefs, and social taboos, many of which disproportionately restrict egg consumption among children and pregnant women. The evidence supports egg intake as a mechanism for meeting nutrient recommendations and a healthy diet in LMIC.
