RESUMEN
OBJECTIVES: To evaluate the support from the available guidance on reporting of health equity in research for our candidate items and to identify additional items for the Strengthening Reporting of Observational studies in Epidemiology-Equity extension. STUDY DESIGN AND SETTING: We conducted a scoping review by searching Embase, MEDLINE, CINAHL, Cochrane Methodology Register, LILACS, and Caribbean Center on Health Sciences Information up to January 2022. We also searched reference lists and gray literature for additional resources. We included guidance and assessments (hereafter termed "resources") related to conduct and/or reporting for any type of health research with or about people experiencing health inequity. RESULTS: We included 34 resources, which supported one or more candidate items or contributed to new items about health equity reporting in observational research. Each candidate item was supported by a median of six (range: 1-15) resources. In addition, 12 resources suggested 13 new items, such as "report the background of investigators". CONCLUSION: Existing resources for reporting health equity in observational studies aligned with our interim checklist of candidate items. We also identified additional items that will be considered in the development of a consensus-based and evidence-based guideline for reporting health equity in observational studies.

There are an increasing number of studies on the effect of cassava (Manihot esculenta Crantz) on performance of laying hens with inconsistent outcomes. This study, therefore, used a meta-analytic approach to examine the effect of cassava-based diets on feed intake (FI), feed conversion ratio (FCR) end production data such as hen day egg production (HDEP), egg weight (EW), egg mass (EM), Haugh unit (HU), shell weight (SW) and shell thickness (ST) in laying hens. Two hundred and three studies were identified in a search performed in PubMed, Scopus and Google Scholar databases of which thirteen studies were suitable for the meta-analysis. Subgroup and meta-regression analyses were performed to explore the responses of laying hens to dietary cassava and sources of heterogeneity, respectively using the following moderators: study continent, cassava type, cassava processing methods, inclusion level, layer strain, feeding durations, number of layers and hen's age. Data were pooled using a random-effects model and statistical analyses were performed in OpenMEE software. Results show that cassava increased FI (mean difference MD = 0.97 g/d; 95% confidence intervals (CI) 0.05, 1.90) and reduced egg weight (MD = -0.72 g; 95% CI -1.26, -0.19) and SW (MD = -0.11 g; 95% CI -0.18, -0.04) when compared to control. Laying hens fed cassava diets had HDEP, FCR, EM, ST and HU values that compared favourably with the controls. Subgroup analysis demonstrated that inclusion of cassava at ≤ 25% in layer diets had no deleterious effects on measured outcomes taking cognizance of significant heterogeneity. However, meta-regression results showed that most of the sources of heterogeneity were explained by the studied moderators. In conclusion, ≤25% of cassava (CRM and CPM) can be included in layer diets without adverse effects on feed intake, feed conversion ratio and egg production characteristics, indicating that cassava has a very bright future as an energy source in the diets of laying hens.
RESUMEN
Background: Due to lack of targeted treatment options and inconsistent utilization of histologic endpoints among clinical trials, identifying efficacious pharmacotherapies for nonalcoholic steatohepatitis [NASH] has proven challenging. Methods: A thorough systematic review and frequentist random-effects network meta-analysis was performed across all randomized clinical trials reporting a pharmacotherapeutic intervention on biopsy-proven NASH. Primary outcomes were based on the most current, up-to-date recommended histologic endpoints. Results: A total of 40 RCTs were identified including 6593 total patients. The most effective and statistically significant treatment interventions for minimum two-point improvement in NAFLD Activity Score were aldafermin 1 mg [RR 7.69, 95% CI 2.00; 29.57], vitamin E 800 IU in combination with pioglitazone 45 mg [RR 3.38, 95% CI 1.88; 6.07], pioglitazone 45 mg [RR 3.29, 95% CI 1.74; 6.22], vitamin E 800 IU [RR 2.06, 95% CI 1.33; 3.18], resmetirom 80 mg [RR 1.74, 95% CI 1.03; 2.94], obeticholic acid 25 mg [RR 1.63, 95% CI 1.32; 2.01], and obeticholic acid 10 mg [RR 1.31, 95% CI 1.02; 1.67]). The most robust pharmacotherapies for NASH resolution without worsening fibrosis were found to be aldafermin 1 mg [RR 5.77, 95% CI 1.48; 22.51], pioglitazone 45 mg [RR 2.65, 95% CI 1.43; 4.91], vitamin E 800 IU in combination with pioglitazone 45 mg [RR 2.64, 95% CI 1.36; 5.12], pioglitazone 30 mg [RR 2.46, 95% CI 1.56; 3.88], vitamin E 800 IU [RR 1.90, 95% CI 1.20; 3.00], and obeticholic acid 25 mg [RR 1.52, 95% CI 1.03; 2.23]). Obeticholic acid had a significant improvement on fibrosis. Multiple interventions were found to improve individual histologic scores across secondary outcome analyses and are detailed below. Conclusion: This novel systematic review and network meta-analysis represents the most comprehensive investigation to date regarding the pharmacotherapeutic options for biopsy-proven NASH using current recommended histologic endpoints.
RESUMEN
BACKGROUND: Atopic dermatitis (AD) is a chronic, inflammatory skin disorder characterised by intense itch and eczematous lesions. Rising prevalence of AD has been observed worldwide including in Asia. Understanding the risk factors associated with AD may explain its pathogenicity and identify new preventive strategies and treatments. However, AD-associated risk factors and comorbidities specific to Asia have not been systematically reviewed. METHODS: We performed a systematic review in accordance with the Preferred Reporting Item for Systematic Review and Meta-Analyses (PRISMA) guidelines and summarised epidemiological studies investigating personal, family, and environmental factors and comorbidities associated with AD in Asia. Significant factors were assessed if they can be altered through lifestyle practices and further classified into non-modifiable and modifiable factors. Meta-analysis using the random-effect model was also conducted to provide an overall estimate for several significant factors. RESULTS: We identified a total of 162 epidemiological studies conducted in Asia. Among non-modifiable factors, a family history of atopic diseases was the most reported, suggesting the involvement of genetics in AD pathogenesis. Among modifiable factors, the results of meta-analyses revealed maternal smoking as the strongest risk factor with a pooled odds ratio (OR) of 2.95 (95% CI, 2.43-3.60), followed by active smoking (pooled OR, 1.91, 95% CI, 1.41-2.59). CONCLUSION: While a family history may aid clinicians in identifying high-risk individuals, literature has long suggested the importance of gene-environment interaction. This review identified several modifiable factors including medical treatments, indoor and outdoor environmental exposure, and personal and family lifestyle specific to Asia. Based on the meta-analyses performed, prevention strategies against AD may start from changing personal and family lifestyle choices, especially smoking habits.
