We conducted a systematic review and meta-analysis to characterize the epidemiology and burden of HZ in LAC. Bibliographic databases and grey literature sources were consulted to find studies published (January 2000-February 2020) with epidemiological endpoints: cumulative incidence and incidence density (HZ cases per 100,000 personyears), prevalence, case-fatality rates, HZ mortality, hospitalization rates, and rates of each HZ complication. Twenty-six studies were included with most studies coming from Brazil. No studies reported the incidence of HZ in the general population. In population at higher risk, the cumulative incidence ranged from 318-3,423 cases of HZ per 100,000 persons per year of follow-up. The incidence density was 6.4-36.5 cases per 1,000 person-years. Age was identified as a major risk factor towards HZ incidence which increase significantly in people >50 years of age. Hospitalization rates ranged from 3%-35.7%. The in-hospital HZ mortality rate ranged from 0%-36%. Overall, HZ mortality rates were found to be higher in females across all age groups and countries. The incidence of HZ complications (such as post-herpetic neuralgia, ophthalmic herpes zoster, and Ramsay Hunt syndrome) was higher in the immunosuppressed compared to the immunocompetent population. Acyclovir was the most frequently used therapy. Epidemiological data from Ministry of Health databases (Argentina, Brazil, Colombia, Chile y Mexico) and Institute for Health Metrics and Evaluation's Global Burden of Disease project reported stable rates of hospitalizations and deaths over the last 10 years. High-risk groups for HZ impose a considerable burden in LAC. They could benefit from directed healthcare initiatives, including adult immunization, to prevent HZ occurrence and its complications.

Short-term exposure (from one hour to days) to selected air pollutants has been associated with human mortality. This systematic review was conducted to analyse the evidence on the effects of short-term exposure to particulate matter with aerodynamic diameters less or equal than 10 and 2.5 µm (PM 10, PM 2.5), nitrogen dioxide (NO 2), and ozone (O 3), on all-cause mortality, and PM 10 and PM 2.5 on cardiovascular, respiratory, and cerebrovascular mortality. Methods: We included studies on human populations exposed to outdoor air pollution from any source, excluding occupational exposures. Relative risks (RRs) per 10 µg/m 3 increase in air pollutants concentrations were used as the effect estimates. Heterogeneity between studies was assessed using 80% prediction intervals. Risk of bias (RoB) in individual studies was analysed using a new domain-based assessment tool, developed by a working group convened by the World Health Organization and designed specifically to evaluate RoB within eligible air pollution studies included in systematic reviews. We conducted subgroup and sensitivity analyses by age, sex, continent, study design, single or multicity studies, time lag, and RoB. The certainty of evidence was assessed for each exposure-outcome combination. The protocol for this review was registered with PROSPERO (CRD42018087749). Results: We included 196 articles in quantitative analysis. All combinations of pollutants and all-cause and cause-specific mortality were positively associated in the main analysis, and in a wide range of sensitivity analyses. The only exception was NO 2 , but when considering a 1-hour maximum exposure. We found positive associations between pollutants and all-cause mortality for PM 10 (RR: 1.0041; 95% CI: 1.0034-1.0049), PM 2.5 (RR: 1.0065; 95% CI: 1.0044-1.0086), NO 2 (24-hour average) (RR: 1.0072; 95% CI: 1.0059-1.0085), and O 3 (RR: 1.0043; 95% CI: 1.0034-1.0052). PM 10 and PM 2.5 were also positively associated with cardiovascular, respiratory, and cerebrovascular mortality. We found some degree of heterogeneity between studies in three exposure-outcome combinations, and this heterogeneity could not be explained after subgroup analysis. RoB was low or moderate in the majority of articles. The certainty of evidence was judged as high in 10 out of 11 combinations, and moderate in one combination. Conclusions: This study found evidence of a positive association between short-term exposure to PM 10 , PM 2.5 , NO 2 , and O 3 and all-cause mortality, and between PM 10 and PM 2.5 and cardiovascular, respiratory and cerebrovascular mortality. These results were robust through several sensitivity analyses. In general, the level of evidence was high, meaning that we can be confident in the associations found in this study.

Methods: A systematic search was carried out in MEDLINE, EMBASE, CENTRAL, SOCINDEX, and LILACS databases. Studies from LAC published from January 1989 to December 2015 were included and were analyzed by subgroups disaggregated by decade of data, country, bias risk, sex, and age group. Results: Of 1 254 studies evaluated by full text, 29 articles were included, of which 25 were chosen for meta-analysis. All included studies were cross-sectional or surveillance, primarily from Brazil and Mexico.Low income was associated with higher prevalence of active smoking (odds ratio [OR] 1.62; 95% confidence interval [95%CI] 1.34-1.96) than high income (reference). A dose-response effect trend was observed: middle income (OR 1.23; 95%CI 1.00-1.52) and low income (OR 1.64; 95%CI 1.17-2.30). This association was greater in men (OR 2.22; 95%CI 1.77-2.78) than in women (OR 1.6; 95%CI 1.11-2.47). Conclusions: An inverse relationship was observed between income and tobacco-use prevalence. Further efforts are required to determine this relationship in special populations, such as adolescents and pregnant women. This research can be useful for policymakers by improving tobacco control strategies and for characterizing public health equity issues.

HIV and AIDS may also have substantial impacts on the workforce in sectors other than health. Workplace programmes aim to improve access for health workers and other workers to HIV prevention, treatment and support.

Search strategy We searched in MEDLINE, EMBASE, Cochrane Library, LILACS, Clinical Trials.gov, International Clinical Trials Registry Platform, reference lists and contacted field experts. Selection criteria, data collection and analysis Randomized controlled trials comparing any corticosteroids against each other or against placebo. Three researchers independently selected, extracted data and assessed the risk of bias of the included studies by using EROS and COVIDENCE software. We performed a pairwise meta-analysis and Bayesian network meta-analysis. Main results We included 45 trials (11227 women, 11878 infants). There was no important difference between corticosteroids in neonatal death (odds ratio[OR] 1.05; 95% confidence interval 0.62-1.84; moderate-certainty evidence[CE]), neurodevelopmental disability (OR 1.03; 0.80-1.33; moderate-CE), intraventricular haemorrhage (OR 1.04; 0.56-1.78); low-CE) and birthweight (+5.29 gr; -49.79 to 58.97; high-CE). Compared with betamethasone, dexamethasone may reduce chorioamnionitis (OR 0.70; 0.45-1.06; moderate-CE), foetal death (OR 0.81; 0.24-2.41; low-CE) while may increase puerperal sepsis (OR 2.04; 0.72-6.06; low-CE) and respiratory distress syndrome (OR 1.34; 0.96-2.11; moderate-CE), however, the confidence interval indicates both beneficial and detrimental effects. Conclusions We found no important difference on neonatal death, neurodevelopmental disability, intraventricular haemorrhage and birthweight between corticosteroids. Compared with betamethasone, dexamethasone may reduce chorioamnionitis and foetal death, but may increase endometritis/puerperal sepsis and respiratory distress syndrome. Further research is warranted to improve the certainty of evidence. Keywords preterm birth, antenatal corticosteroids, dexamethasone, betamethasone, systematic review, network meta-analysis

There is no information summarizing the complete body of evidence about IBD in developing regions, including Latin America. To estimate the burden of IBD in Latin America. We conducted a systematic review searching published and unpublished studies on major international and regional databases from January 2000 to September 2015. Outcomes considered were incidence, prevalence, mortality, hospitalization attributable, treatment patterns, comparative effectiveness, patient-reported outcomes, and adherence to treatment. Pairs of reviewers independently selected, extracted, and assessed the risk of bias of the studies. Discrepancies were solved by consensus. We retrieved 3445 references, finally including 25 studies. Only 19% of the observational studies had a low risk of bias for participant selection and 60% were based on ...
