SUMMARYThe rapid spread of the Zika virus (ZIKV) in the Americas and its potential association with thousands of suspected cases of microcephaly in Brazil and higher rates of Guillain-Barré syndrome meet the conditions for a Public Health Emergency of International Concern, as stated by the World Health Organization in February 2016. Two months later, the Centers for Disease Control and Prevention (CDC) announced that the current available evidence supports the existence of a causal relationship between prenatal Zika virus infection and microcephaly and other serious brain anomalies. Microcephaly can be caused by several factors, and its clinical course and prognosis are difficult to predict. Other pathogens with proven teratogenicity have been identified long before the current ZIKV epidemic. Despite the growing number of cases with maternal signs of infection and/or presence of ZIKV in tissues of affected newborns or fetuses, it is currently difficult to assess the magnitude of increase of microcephaly prevalence in Brazil, as well as the role of other factors in the development of congenital neurological conditions. Meanwhile, health agencies and medical organizations have issued cautious guidelines advising health care practitioners and expectant couples traveling to, returning from, or living in affected areas. Analogous to dengue virus (DENV) epidemics, ZIKV has the potential to become endemic in all countries infested byAedesmosquitoes, while new mutations could impact viral replication in humans, leading to increased virulence and consequently heightened chances of viral transmission to additional naive mosquito vectors. Studies are urgently needed to answer the questions surrounding ZIKV and its role in congenital neurological conditions.

“…A prenatal care allows for early diagnosis of fetal or maternal problems that may place the fetus in risk, and can therefore prevent complications and incidents that may lead to an early labor [23]. Therefore prenatal care must be even more encompassing among women at greater risk of preterm birth, such as multiple pregnancies and fetuses with congenital malformations [16, 24]. …”

BackgroundPreterm birth is a serious public health problem, as it is linked to high rates of neonatal and child morbidity and mortality. The prevalence of premature births has increased worldwide, with regional differences. The objective of this study was to analyze the trend of preterm births in the state of Paraná, Brazil, according to Macro-regional and Regional Health Offices (RHOs).MethodsThis is an ecological time series study using preterm births records from the national live birth registry system of Brazil’s National Health Service - Live Birth Information System (Sinasc), for residents of the state of Paraná, Brazil, between 2000 and 2013. The preterm birth rates was calculated on a yearly basis and grouped into three-year periods (2000–2002, 2003–2005, 2006–2008, 2009–2011) and one two-year period (2012–2013), according to gestational age and mother’s Regional Health Office of residence. The polynomial regression model was used for trend analysis.ResultsThe predominance of preterm birth rate increased from 6.8 % in 2000 to 10.5 % in 2013, with an average increase of 0.20 % per year (r2 = 0.89), and a greater share of moderate preterm births (32 to <37 weeks), which increased from 5.8 % to 9 %. The same pattern was observed for all Macro-regional Health Offices, with highlight to the Northern Macro-Regional Office, which showed the highest average rate of prematurity and average annual growth during that period (7.55 % and 0.35 %, respectively). The trend analysis of preterm birth rates according to RHO showed a growing trend for almost all RHOs – except for the 7th RHO where a declining trend was observed (−0.95 a year); and in the 20th, 21st and 22nd RHOs which remained unchanged. In the last three-year of the study period (2011–2013), no RHO showed preterm birth rates below 7.3 % or prevalence of moderate preterm birth below 9.4 %.ConclusionsThe results show an increase in preterm births with differences among Macro-regional and RHOs, which indicate the need to improve actions during the prenatal period according to the specificities of each region.

“…Pregnant adolescents or older women from unfavorable social classes and with low education levels are more likely to develop more severe complications during pregnancy. Intercurrences such as hypertension, pre-eclampsia, urinary tract infection (UTI), premature labor and fetal growth restriction are described as the main causes of hospitalization for the treatment and prevention of undesirable consequences (4)(5)(6)(7) such as maternal, fetal and infant morbidity and mortality.…”

Objective To analyze the occurrence, profile and main causes of hospitalization during pregnancy according to the type of childbirth financial coverage. Method A cross-sectional population-based study carried out with puerperal women through a stratified sample, calculated according to the hospital and the type of childbirth financial coverage source: public sector (SUS) or private (not SUS). The sociodemographic profile, the rate of obstetric complications and the causes of hospitalization were analyzed, coded according to International Classification of Diseases. Results A total of 928 postpartum women were interviewed, of whom 32.2% reported at least one hospitalization during pregnancy. Those with childbirth covered by SUS were less favored because they were the majority among hospitalized women (57.2%), with a higher percentage of adolescents (18.1%), lower education level (91.8%), low family income (39.3%) and fewer prenatal consultations (25.3%). The most frequent causes of hospitalization were "other maternal diseases that complicate pregnancy" (24.6%) (with emphasis on anemia and influenza), urinary tract infection (13.1%), preterm labor (8.7%) and hypertension (7.2%). Conclusion Anemia, influenza, urinary tract infection, preterm labor and hypertension should especially be prevented and treated to avoid hospital admissions during pregnancy, especially among pregnant women covered by SUS.
