Infant mortality in southern Brazil: a population based study of causes of death.

SARS-CoV-2 is an RNA virus, responsible for causing an acute respiratory syndrome, which became known worldwide for its rapid spread and for causing the pandemic of a new disease: COVID-19. Thus, epidemiological studies have been developed in order to determine the extent of the problems and the magnitude of the disease. The present study aimed to evaluate the seroprevalence of SARS-CoV-2 infection and its relationship with socio-demographic and clinical-epidemiological factors in the city of Chapecó, Santa Catarina, Brazil. It was a quantitative, epidemiological, observational, cross-sectional, population-based study with 2179 participants. Socio-demographic, associated behavioral, aggravating and comorbid parameters were evaluated, relating them to positivity or not in the rapid test implemented. The rapid test identified 22.2% of the diagnosed seroprevalence of COVID-19 in the municipality in question. A higher incidence of cases was observed in people living with other people, in people who had contact with positive cases, and in symptomatic patients, corroborating with current studies. The results highlight the importance of clinical-epidemiological studies for the understanding and control of COVID-19.

Abstract Background Infant-mortality rates have been declining in many low- and middle-income countries, including Brazil. Information on causes of death and on socio-economic inequalities is scarce. Methods Four birth cohorts were carried out in the city of Pelotas in 1982, 1993, 2004 and 2015, each including all hospital births in the calendar year. Surveillance in hospitals and vital registries, accompanied by interviews with doctors and families, detected fetal and infant deaths and ascertained their causes. Late-fetal (stillbirth)-, neonatal- and post-neonatal-death rates were calculated. Results All-cause and cause-specific death rates were reduced. During the study period, stillbirths fell by 47.8% (from 16.1 to 8.4 per 1000), neonatal mortality by 57.0% (from 20.1 to 8.7) and infant mortality by 62.0% (from 36.4 to 13.8). Perinatal causes were the leading causes of death in the four cohorts; deaths due to infectious diseases showed the largest reductions, with diarrhoea causing 25 deaths in 1982 and none in 2015. Late-fetal-, neonatal- and infant-mortality rates were higher for children born to Brown or Black women and to low-income women. Absolute socio-economic inequalities based on income—expressed in deaths per 1000 births—were reduced over time but relative inequalities—expressed as ratios of mortality rates—tended to remain stable. Conclusion The observed improvements are likely due to progress in social determinants of health and expansion of health care. In spite of progress, current levels remain substantially greater than those observed in high-income countries, and social and ethnic inequalities persist.

Abstract Introduction The study aims to assess the changes in prevalence and mortality of gastroschisis, and to identify associated anomalies. Materials and Methods It is a population-based nationwide study. All gastroschisis cases were identified in the Finnish Register of Congenital Malformations and the Care Register for Health Care from 1993 to 2014 including live births, stillbirths, and terminations of pregnancy due to fetal anomalies. Associated anomalies were recorded, and analyzed, and prevalence and infant mortality were calculated. Results There were 320 cases of gastroschisis; 235 (73%) live births, 16 (5%) stillbirths, and 69 (22%) terminations of pregnancy. Live birth prevalence of gastroschisis in Finland was lower than generally reported (1.73 in 10,000). However, due to relatively high rates of abortion, our total prevalence of 2.57/10,000 was similar with other reports. The most common risk factor was young maternal age. Babies with gastroschisis were born prematurely, on average on the 36th week and most are delivered by caesarean section. There was a significant increasing trend in live birth prevalence (p = 0.0018). Overall infant mortality was 7.7% (18/235), 7.2% (16/222) in simple gastroschisis and 15% (2/13) in complex gastroschisis. Associated anomalies were rare both in aborted fetuses and neonates, and there was only one case with a chromosomal abnormality. Conclusion Gastroschisis is usually an isolated anomaly with increasing birth prevalence and excellent survival rates. Regardless of the good prognosis, the abortion rates in Finland are higher than previously reported, and we hypothesize this to be due to lack of appropriate antenatal counselling.
