Estimativa dos coeficientes específicos de mortalidade infantil segundo peso ao nascer no município de São Paulo (Brasil)

Foi estimada a distribuição do peso ao nascer da coorte dos recém-nascidos que deu origem aos óbitos infantis estudados pela Investigação Interamericana de Mortalidade na Infância no projeto de São Paulo (1968-70) e determinados os riscos de óbito associados a cada intervalo de peso de nascimento. Assim, foram apurados coeficientes de mortalidade infantil de 305,5, 50,2 e 34,4 para recém-nascidos de baixo peso, peso deficiente e peso superior a 3.000 g. A comparação destes coeficientes com os registrados na área americana incluída na investigação citada (Califórnia), revelou excesso de mortalidade, particularmente notável não para os recém-nascidos de baixo peso, mas para os recém-nascidos de peso superior a 3.000 g. O ajuste da mortalidade de São Paulo (Brasil) à distribuição do peso ao nascer observada na Califórnia foi capaz de explicar 15% do excesso da mortalidade infantil e 21% do excesso da mortalidade neonatal de São Paulo.By means of the birth-rate distribution found to exist during the Inter-American Investigation of Mortality in Childhood in S. Paulo (1968-70) the infant death rate association with each birth-weight interval was estimated. The infant mortality rates were 305.5, 50.2 and 34.4 respectively for low birth-weight, deficient weight and weight above 3,000 grams. Compared with the rates found in California, USA, by the same Investigation, the infant mortality rates in S. Paulo are higher, particularly for mortality associated with birth-weight of above 3,000 grams. The adjustment of infant mortality rates in S. Paulo according to the birth-weight distribution found in California led to the conclusion that, at that period, only 15% of the excess of the infant mortality of S. Paulo could be attributed exclusively to birth-weight. In the case of neonatal mortality, 21% of the mortality excess in S. Paulo could be attributed to birth-weight

Part I. What has happened in terms of some of the unique elements of shift in diet, activity, obesity, and other measures of morbidity and mortality within different regions of the world? Is obesity replacing or adding to undernutrition? Evidence from different social classes in Brazil

Objective: To describe time trends in under- and overnutrition in different regional and income strata of the child and adult population of Brazil. Design: Nation-wide surveys conducted in 1975, 1989 and 1996/7 in probabilistic samples of 1-4-year-old children and adults 20 years and over. Time trends refer to stunting, wasting and overweight prevalences among children and age-adjusted underweight and obesity prevalences among adults (95% confidence intervals included). Subjects: Individuals examined by each survey in each age group ranged from 1796 young children in 1996 to 78031 adults in 1975. Setting: North-eastern and south-eastern regions of Brazil. Results: Undernutrition indicators declined intensively and continuously among children and adults in all region and income strata. Obesity remained low and relatively stable among children, but increased intensively and continuously in all regions and income strata among adult males. Obesity also increased intensively and continuously among adult women from the less economically developed region of Brazil (the north-eastern region) and among lower-income women from the more developed region (the south-eastern region). Higher-income women from the more developed region had a significant increase in obesity from 1975 to 1989, followed by a significant decline from 1989 to 1997. Conclusions: Undernutrition in young children is being controlled in Brazil without evidence of increasing obesity. However, obesity is rapidly replacing undernutrition in most gender, region and income strata of the adult population. Adult obesity is already more frequent than adult undernutrition in the more economically developed region, among all higher-income groups, and also among lower-income women living in the more developed region. These lower-income women are significantly more exposed than their higher-income counterparts to both undernutrition and obesity

House dust fungal communities’ characterization: a double take on the six by sixty by six (6 × 60 × 6) project

Fungi are a group of microbes that are found with particular incidence in the indoor environment. Their direct toxicity or capability of generating toxic compounds has been associated with a large number of adverse health effects, such as infectious diseases and allergies. Given that in modern society people spend a large part of their time indoors; fungal communities’ characterization of this environmental compartment assumes paramount importance in the comprehension of health effects.

ASTEC -- the Aarhus STellar Evolution Code

The Aarhus code is the result of a long development, starting in 1974, and still ongoing. A novel feature is the integration of the computation of adiabatic oscillations for specified models as part of the code. It offers substantial flexibility in terms of microphysics and has been carefully tested for the computation of solar models. However, considerable development is still required in the treatment of nuclear reactions, diffusion and convective mixing.Comment: Astrophys. Space Sci, in the pres

Green manure in coffee systems in the region of Zona da Mata, Minas Gerais: characteristics and kinetics of carbon and nitrogen mineralization.

The use of green manure may contribute to reduce soil erosion and increase the soil organic matter content and N availability in coffee plantations in the Zona da Mata, State of Minas Gerais, in Southeastern Brazil. The potential of four legumes (A. pintoi, C. mucunoides, S. aterrimum and S. guianensis)to produce above-ground biomass, accumulate nutrients and mineralize N was studied in two coffee plantations of subsistence farmers under different climate conditions. The biomass production of C. mucunoides was influenced by the shade of the coffee plantation.C. mucunoides tended to mineralize more N than the other legumes due to the low polyphenol content and polyphenol/N ratio. In the first year, the crop establishment of A. pintoi in the area took longer than of the other legumes, resulting in lower biomass production and N2 fixation. In the long term, cellulose was the main factor controlling N mineralization. The biochemical characteristics, nutrient accumulation and biomass production of the legumes were greatly influenced by the altitude and position of the area relative to the sun

O papel da atenção primária à saúde no enfrentamento de IST

A atenção Primária à Saúde é considerada a porta de entrada preferencial do usuário no Sistema Único de Saúde (SUS). A partir dela é possível garantir, entre outros, o diagnóstico e tratamento precoces de doenças como as infecções sexualmente transmissíveis (IST), hepatite B e C, HIV e sífilis. Descrever a experiência de uma ação realizada com usuários em uma Unidade Básica de Saúde (UBS) sobre IST, com o intuito de melhorar a adesão da população ao cuidado com IST e minimizar seus riscos. Trata-se de um estudo descritivo do tipo relato de experiência, desenvolvido durante as atividades práticas dos estudantes da graduação de medicina na UBS de Jardim Brasil V, Olinda-PE, em setembro de 2020. Estiveram envolvidos 20 usuários da UBS de demanda espontânea, após divulgação prévia a esta ação, considerando os cuidados em tempos de pandemia. Foi realizada uma triagem com testes rápidos para sífilis, HIV, hepatite B e C, além de receberem informações sobre IST e da importância da investigação precoce. A maioria dos participantes foram do sexo feminino, 15% testaram positivo (sífilis). Nenhum deles tinham realizado estes testes antes. Apenas 15% dos voluntários tinham conhecimento dos testes de triagem das IST e compreendiam a importância desta realização. O atendimento imediato de uma pessoa com IST não é apenas uma ação curativa, mas também visa à interrupção da cadeia de transmissão, à prevenção de outras IST e complicações decorrentes destas infecções
