A recent European randomized trial – Tracheal Occlusion To Accelerate Lung Growth – demonstrated that fetoscopic endoluminal tracheal occlusion (FETO) is associated with increased postnatal survival among infants with severe congenital diaphragmatic hernia (CDH). However, this differs in middle-income countries such as Brazil, where abortion is illegal and neonatal intensive care is inadequate. This study evaluated the effects of FETO on improving the survival of infants with moderate-to-severe CDH in isolated and non-isolated cases. This retrospective cohort study selected 49 fetuses with CDH, a normal karyotype, and a lung-to-head ratio (LHR) of <1 from a single national referral center for fetal surgery in São Paulo, Brazil, between January 2016 and November 2019. FETO was performed between 26 and 29 weeks of gestation. The primary outcomes were infant survival until discharge from the neonatal intensive care unit and survival until six months of age. Forty-six women with singleton fetuses having severe CDH underwent prenatal intervention with FETO. Infant survival rates until discharge and at six months of age were both 38 %. The observed-to-expected LHR increased by 25 % after FETO in neonates who survived until discharge. Spontaneous intrauterine death occurred in four growth-restricted fetuses after FETO. Preterm birth in <37 weeks and preterm rupture of membranes in <34 weeks occurred in 56.5 % (26) and 26 % (12) cases, respectively. FETO may increase neonatal survival in fetuses with severe CDH, particularly in countries with limited neonatal intensive care. [ABSTRACT FROM AUTHOR]

Universities have been entrusted with the task of qualifying professionals for their future practice. In light of this, the present study analysed the competencies perceived by 80 physical education students of a public university in the state of Santa Catarina, Brazil, enrolled in the subject Outdoor Adventure Sports. An exploratory descriptive investigation was conducted with a qualitative approach. The content analysis technique was applied, and analysis categories were created according to a specific professional competence model. The findings indicate that the students perceived themselves as more competent in social/vocational, intra-professional, ethical and theoretical aspects of the profession, respectively. This study demonstrates that principles and values of outdoor adventure sports could contribute to the perception and development of some competencies, depending on the context and forms of mediation.

The presence of ochratoxin A (OTA) is evaluated using thin layer chromatography (TLC) with a charge-coupled detector (CCD) in 88 red wine samples (2009 vintage) from Brazil. Samples included 75 wines from Rio Grande do Sul, nine from Santa Catarina and four from Paraná state; 56 wines were Cabernet Sauvignon and 32 were Merlot varieties. The method included the analysis of fluorescent images, acquired under UV light, using ImageJ software. Mean recovery of OTA was 82.3% using immunoaffinity columns (IAC). The limits of quantification (LOQ) and detection (LOD) were 0.8 and 0.2 µg l−1, respectively. Results showed a 5.7% contamination of OTA, with five positive samples – three Cabernet Sauvignon and two Merlot. Santa Catarina and Paraná showed one positive sample each, although the concentrations were below the limit of quantification. The highest concentration found was 0.84 µg l−1 in one sample from Rio Grande do Sul. [ABSTRACT FROM PUBLISHER]

Abstract: A method has been developed to determine 10 elements in Brazilian red wines using high-resolution continuum source flame atomic absorption spectrometry, a technique that allows the fast sequential determination of an essentially unlimited number of elements per sample, each one under previously optimized conditions. All measurements were made without sample preparation, using aqueous standard solutions for calibration. The results were in agreement within 99% of confidence (t-test) with those obtained by inductively coupled plasma optical emission spectrometry. The same grape, Cabernet sauvignon, was used in all experiments, and the wines from each region were prepared especially for this investigation in order to avoid any confusion due to grapes from other regions, which are often used in commercial wines. The elements K, Mn, Rb and Sr were found to be the best indicators for the origin of the wines, based on a Principal Component Analysis. [Copyright &y& Elsevier]
