Gravidez na adolescência: perfil sociodemográfico de adolescentes grávidas no período de 2015 até 2019

Objective: to analyze the sociodemographic profile of pregnant adolescents in Brazil between 2015 and 2019. Method: descriptive cross-sectional study, with a quantitative approach, coming from the Information Technology Department of the Unified Health System. Data analysis used absolute and relative frequencies (%). Results: 2,405,248 pregnant adolescents were registered. The majority of pregnancies occurred in girls aged 15 to 19 years (95.2%), of a brown color (65.4%), single (64.9%), with 8 to 11 years of maternal education (66.9%). As for the characteristics of pregnancy, 98.7% were single pregnancy, lasting 37 to 41 weeks (81.7%) and vaginal type of delivery (61.2%). The temporal analysis showed a drop from 2015 to 2019. Conclusion: teenage pregnancy is a complex event in which attention must address a biopsychosocial context.  Thus, delineating the sociodemographic profile of these adolescents is necessary, as it makes it possible to get to know the population under study and its vulnerability conditions.Objetivo: analizar el perfil sociodemográfico de las adolescentes embarazadas en Brasil entre los años 2015 y 2019. Método: estudio descriptivo transversal, con enfoque cuantitativo, del Departamento de Informática del Sistema Único de Salud. En el análisis de los datos se utilizaron frecuencias absolutas y relativas (%). Resultados: se registraron 2.405.248 adolescentes embarazadas. La mayoría de los embarazos se produjeron en chicas de entre 15 y 19 años (95,2%), morenas (65,4%), solteras (64,9%), con entre 8 y 11 años de educación materna (66,9%). En cuanto a las características del embarazo, el 98,7% fueron embarazos únicos, con una duración de 37 a 41 semanas (81,7%) y tipo de parto vaginal (61,2%). El análisis temporal mostró un descenso de 2015 a 2019. Conclusión: el embarazo en la adolescencia constituye un evento complejo en el que se debe prestar atención a un contexto biopsicosocial.  Por lo tanto, es necesario delinear el perfil sociodemográfico de los adolescentes, ya que permite conocer a la población en estudio y sus condiciones de vulnerabilidad.Objetivo: analisar o perfil sociodemográfico de adolescentes grávidas no Brasil entre os anos de 2015 até 2019.

Hipertermia maligna en Brasil: análisis de la actividad del hotline en 2009

BACKGROUND AND OBJECTIVES: Malignant hyperthermia (MH) is a pharmacogenetic disease that causes abnormal hypermetabolic reaction to halogenated anesthetics and/or depolarizing muscle relaxants. In Brazil, there is a hotline telephone service for MH since 1991, available 24 hours a day in São Paulo. This article analyzes the activity of the Brazilian hotline service for MH in 2009. METHODS: Prospective analysis of all phone calls made to the Brazilian hotline service for MH from January to December 2009. RESULTS: Twenty-two phone calls were received: 21 from the South/Southeast region of Brazil and one from the North region. Fifteen calls were requests for general information about MH. Seven were about suspected MH acute episodes, two of which were not considered as MH. In five episodes compatible with MH, all patients received halogenated volatile anesthetics (2, isoflurane; 3, sevoflurane) and one also used succinylcholine; there were four men and one woman, with a mean age of 18 years (2-27). The problems described in the five MH episodes were tachycardia (5), increased expired carbon dioxide (4), hyperthermia (3), acidemia (1), rhabdomyolysis (1), and myoglobinuria (1). One patient received dantrolene. All five patients with MH episodes were follow-up in the intensive care unit and recovered without sequelae. Susceptibility to MH was later confirmed in two patients by in vitro muscle contracture test. CONCLUSIONS: The number of calls per year in the Brazilian hotline service for MH is still low. The characteristics of MH episode were similar to those reported in other countries. The knowledge of MH in Brazil needs to be increased.JUSTIFICATIVA Y OBJETIVOS: La Hipertermia Maligna (HM) es una enfermedad farmacogenética, con una reacción hipermetabólica anormal a los anestésicos halogenados y/o relajantes musculares despolarizantes. Desde 1991 existe un servicio hotline de atención telefónica para la HM en Brasil a disposición las 24 horas del día en São Paulo. Este artículo analiza la actividad del servicio brasileño de hotline para la HM en el 2009. MÉTODOS: Análisis prospectivo de todas las llamadas telefónicas realizadas al servicio brasileño de hotline para la HM, desde enero a diciembre de 2009. RESULTADOS: Se recibieron 22 llamadas; 21 provenientes del Sur y Sudeste de Brasil y una del Norte. Quince eran solicitudes de informaciones generales sobre la HM. Siete fueron sobre sospechas de crisis agudas de HM, de las cuales dos no fueron consideradas como HM. En las cinco crisis compatibles con la HM, todos los pacientes recibieron anestésicos inhalatorios halogenados (2 isoflurano, 3 sevoflurano) y uno también usó succinilcolina. Había cuatro hombres y una mujer, con un promedio de edad de 18 años (2-27). Los problemas descritos en las cinco crisis de HM: taquicardia (cinco), aumento del gas carbónico espirado (cuatro), hipertermia (tres), acidemia (uno), rabdomiólisis (uno) y mioglobinuria (uno). Un paciente recibió dantrolene. Todos los cinco pacientes con crisis de HM recibieron acompañamiento en la unidad de cuidados intensivos y se recuperaron sin secuelas. La susceptibilidad a la HM fue posteriormente confirmada en dos pacientes por medio del test de la contractura muscular in vitro. CONCLUSIONES: El número de llamadas por año al servicio brasileño de hotline para la HM todavía es pequeño. Las características de las crisis fueron similares a las descritas en otros países. Es necesario aumentar el conocimiento que se tiene sobre la HM en Brasil.JUSTIFICATIVA E OBJETIVOS: Hipertermia maligna (HM) é doença farmacogenética, com reação hipermetabólica anormal a anestésicos halogenados e/ou relaxantes musculares despolarizantes.

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

The application of omics in ruminant production: a review in the tropical and sub-tropical animal production context

The demand for animal products (e.g. dairy and beef) in tropical regions is expected to increase in parallel with the public demand for sustainable practices, due to factors such as population growth and climate change. The necessity to increase animal production output must be achieved with better management and production technologies. For this to happen, novel research methodologies, animal selection and postgenomic tools play a pivotal role. Indeed, improving breeder selection programs, the quality of meat and dairy products as well as animal health will contribute to higher sustainability and productivity. This would surely benefit regions where resource quality and quantity are increasingly unstable, and research is still very incipient, which is the case of many regions in the tropics. The purpose of this review is to demonstrate how omics-based approaches play a major role in animal science, particularly concerning ruminant production systems and research associated to the tropics and developing countriesinfo:eu-repo/semantics/acceptedVersio
