OBJECTIVES To validate the WHO maternal near-miss criteria and develop a benchmark tool for severe maternal morbidity assessments. METHODS In a multicenter cross-sectional study implemented in 27 referral maternity hospitals in Brazil, a one-year prospective surveillance on severe maternal morbidity and data collection was carried out. Diagnostic accuracy(More)
Menstrual blood loss (MBL) studies are relevant for developing world women as this could be an important cause of anemia. Whenever a contraceptive method is to be used by such women, consideration should be given to the method which least affects the volume of MBL. In 309 women considered as clinically healthy, MBL, serum ferritin, serum iron and hemoglobin(More)
OBJECTIVE This study was conducted to evaluate the effect of two types of IUDs on the amount of menstrual blood loss (MBL): the frameless copper-releasing intrauterine device (IUD) with copper surface area of 330 mm2 (GyneFix; Contrel Research, Ghent, Belgium) and the frameless levonorgestrel (LNG)-releasing intrauterine system (IUS) releasing 14 microg per(More)
BACKGROUND Over the past three decades, the World Health Organization expert panel proposed cesarean delivery rate of 10-15 percent was used as a doctrine for an optimal rate of cesarean delivery despite the lack of concrete evidence. We set out to compile cesarean delivery rates, socioeconomic indicators, and health outcomes by countries in the last three(More)
Increased menstrual blood loss (MBL) associated with intrauterine device (IUD) use may precipitate or aggravate iron deficiency anaemia, adversely affecting the health of women particularly those from developing countries. Studies were conducted to define the association of MBL and iron status in South American women; to determine the level of MBL induced(More)
Expiratory resistive loading (ERL) is used by chronic obstructive pulmonary disease (COPD) patients to improve respiratory function. We, therefore, used a noninvasive tension-time index of the inspiratory muscles (TT(mus) = I/PI(max) x TI/TT, where I is mean inspiratory pressure estimated from the mouth occlusion pressure, PI(max) is maximal inspiratory(More)
Inhaled corticosteroids are often used in the treatment of stable chronic obstructive pulmonary disease (COPD), however, studies of these agents have had mixed results. Previous trials have often excluded subjects with bronchodilator response, have failed to evaluate effect on gas exchange, and have usually looked at only post- rather than prebronchodilator(More)
BACKGROUND The aim of this study was to assess the burden of respiratory disease, considering the influenza A pandemic season (H1N1pdm09), within the Brazilian Network for Surveillance of Severe Maternal Morbidity, and factors associated with worse maternal outcome. METHODS A multicenter cross-sectional study, involving 27 referral maternity hospitals in(More)
Cebocephaly (hypotelorism, single-nostril nose) and ethmocephaly (hypotelorism, interorbital proboscis) lie in the middle of the spectrum of craniofacial changes associated with holoprosencephaly. Because these defects and thorough anatomic studies of them are rare, knowledge concerning morphologic as well as pathogenetic relationships is lacking. We report(More)
