Objective: To systematically analyze the relationship between maternal anemia and low birth weight. Methods: A search of studies was conducted in the main databases (Medline, Embase, Scopus, Web of Science, SciELO, and Lilacs), the gray literature, and the reference lists of selected articles. Cohort and case-control studies that met the eligibility criteria were included in the review. There was no limitation on the language or date of publication. Article selection and data extraction were performed by two independent reviewers. Meta-analyses with random effects, subgroup analyses and meta-regressions were performed. Publication bias was measured using Egger regression and visual funnel plot inspection. Results: A total of 7243 articles were found, of which 71 comprised the systematic review and 68 were included in the meta-analyses. Maternal anemia was associated with low birth weight with an adjusted OR: 1.23 (95% CI: 1.06–1.43) and I2: 58%. The meta-regressions confirmed that the sample size and the methodological quality may partially explain the statistical heterogeneity. Conclusions: Maternal anemia was considered a risk factor for low birth weight.

BackgroundCountries in Latin America and the Caribbean (LAC) have experienced a rapid increase in their proportion of older people. This region is marked by a high prevalence of chronic diseases and disabilities among aging adults. Frailty appears in the context of LAC negatively affecting quality of life among many older people.AimTo investigate the prevalence of frailty among community-dwelling older people in LAC through a systematic review and meta-analysis.MethodsA literature search was performed in indexed databases and in the grey literature. Studies investigating the prevalence of frailty with representative samples of community-dwelling older people in Latin America and the Caribbean were retrieved. Independent investigators carried out the study selection process and the data extraction. A meta-analysis and meta-regression were performed using STATA 11 software. The systematic review was registered at the International Prospective Register of Systematic Reviews under the number CRD42014015203.ResultsA total of 29 studies and 43,083 individuals were included in the systematic review. The prevalence of frailty was 19.6% (95% CI: 15.4–24.3%) in the investigated region, with a range of 7.7% to 42.6% in the studies reviewed. The year of data collection influenced the heterogeneity between the studies.ConclusionFrailty is very common among older people in LAC. As a result, countries in the region need to adapt their health and social care systems to demands of an older population.

A previous search of the major electronic databases revealed that no studies appear to have been conducted to summarize the association between maternal active smoking during pregnancy and low birth weight within the Americas. Therefore, this systematic review may help to fill the information gap. The region of the Americas contains some of the most populous countries in the world; therefore, this study may provide useful data from this massive segment of the world's population.

This prospective, controlled, but not formally randomized study investigates the feasibility and efficiency of an alternative to standard hospitalization for patients with exacerbated chronic obstructive pulmonary disease (COPD), based upon supported discharge with nurse supervision at home.Over a 12-month period, emergency physicians, not directly involved in the study, admitted 205 patients with exacerbated COPD to the authors' respiratory unit. Patients were included in the supported discharge group (n=105) if they voluntarily chose to participate in the programme and lived in the city of Palma de Mallorca (where adequate home support could be provided). Patients not fulfilling these criteria (mainly residents outside the city) served as controls (n=100). Inpatient treatment was standardized in all patients and included oxygen therapy, bronchodilators, antibiotics and steroids.Both groups were comparable in terms of age (mean±sd: 70±10versus65±11 yr for supported discharge and control group, respectively), severity of airflow obstruction (forced expiratory volume in one second 45±18% referenceversus46±19% ref.), comorbidity and socioeconomic status. Length of hospital stay (LOS) in the supported discharge group was shorter (5.9±2.8versus8.0±5.1 days, p<0.001). After discharge, a respiratory nurse visited supported discharge patients at home during 7.3±3.8 days. Only one patient (1%) required hospital readmission during this period of time. The reduced LOS resulted in a lower utilization of hospital beds at any given point in time throughout the study period.Within the framework and potential limitations of this study, the results indicate that the supported discharge programme in Spain: 1) allows a significant reduction in the length of hospital stay of patients hospitalized because of an exacerbation of chronic obstructive pulmonary disease; 2) does not result in an inappropriately increased rate of hospital readmissions; and 3) reduces the utilization of hospital resources.

This study aimed to understand stigma in relation to people living with dementia in São Paulo, Brazil. A critical narrative inquiry methodology was used. Home-based semi-structured interviews were conducted between January and March 2020 with six people living with dementia and 15 family carers. Data analysis was conducted using inductive and deductive techniques. The latter was informed by Link and Phelan's sociological theory of stigma. We found that dementia was commonly viewed by people living with dementia as part of ageing and carers reported low levels of knowledge and awareness about the condition. To avoid negative reactions from people, people living with dementia managed the negative views of dementia by minimising and normalising the condition, by expressing their ability to live an active life, and by emphasising the positive impacts of dementia in their lives. Fear of negative reactions appeared to lead to a selective disclosure of their diagnosis. Among carers, stigmatising attitudes coincided with a strong willingness to provide good care, to protect the person cared for, as well as to understand and validate their own caring experiences, rather than to cause any harm. In doing so, however, carers ended up depersonalising and infantilising people living with dementia, underestimating their capacities, demanding ‘obedience’ and restricting the person's freedom. There is a need to increase awareness about dementia and to provide support and training on person-centred and ethical care for carers in Brazil.
