Influence of climate change on summer cooling costs and heat stress in urban office buildings

Indoor climatic conditions are strongly influenced by outdoor meteorological conditions. It is thus expected that the combined effect of climate change and the urban heat island effect negatively influences working conditions in urban office buildings. Since office buildings are particularly vulnerable to overheating because of the profound internal heat gains, this is all the more relevant. The overheating in office buildings leads to elevated cooling costs or, because additional work breaks are required by legislation in some countries, productivity losses. We have developed a methodology incorporating urban climate modelling and building energy simulations to assess cooling costs and lost working hours in office buildings, both for current-day and future climate, extending towards the end of the twenty-first century. The methodology is tailored to additionally assess the impact and benefits of adaptation measures, and it is designed to be transferable from one city to another. Results for a prototype building located in three different European cities (Antwerp, Bilbao and London) illustrate the challenge in keeping Western-European office buildings comfortable until the end of the twenty-first century without adaptation measures, and the beneficial effect of adequate adjustments. The results further illustrate the large decreases in cooling costs (up to 30%) caused by the introduction of (external) shading and increased night-time ventilation in actively cooled buildings, and the improvements in working conditions in free-running buildings caused by moving workers to cooler locations and splitting workdays in morning and evening shifts

Spatial distribution of leprosy in Brazil: a literature review

Abstract Leprosy remains a public health problem in developing countries. Among communicable diseases, it is one of the leading causes of permanent disability. Brazil had not reached the goal of reducing cases to less than 1 per 10,000 population. This study aimed to analyze the spatial distribution of leprosy cases in Brazil, using a literature review. The search strategy included the LILACS and MEDLINE databases with no language or period restriction. Ecological studies with spatial data analysis were considered as a criterion for the inclusion. We found 38 studies for review after the selection criteria. Among the epidemiological indicators of the disease, the most common was the new case detection rate. Several articles have explored the association between spatial distribution of leprosy and socioeconomic, demographic, and environmental factors. The most common unit of analysis was the municipality. The spatial distribution methods mostly used were: empirical Bayesian method, autocorrelation (Moran’s I index) and Kernel estimates. The distribution of leprosy was very heterogeneous, independent of the unit of analysis. There was a decrease in the rate of detection and among under-15-year-olds, but some regions maintained high endemicity during the study period. The distribution and risk of illness were directly related to living conditions of the population. Improved access to health services was associated with increased detection rate in some regions. Spatial analysis seems to be a very useful tool to study leprosy and to guide interventions and surveillance

Desigualdades na tendência da sífilis congênita no município de Niterói, Brasil, 2007 a 2016

Objetivo. Descrever a distribuição temporal e as características epidemiológicas da sífilis congênita (SC) em Niterói, Sudeste do Brasil, de 2007 a 2016. Métodos. Este estudo descritivo de série temporal da incidência de SC utilizou os dados do Sistema de Informação de Agravos de Notificação (SINAN) e do Sistema de Informações sobre Nascidos Vivos (SINASC). A amostra incluiu todos os casos notificados. Além disso, foi realizado um relacionamento probabilístico entre SINAN e SINASC para recuperar informações ignoradas. A série temporal foi estimada por regressão logarítmica, de acordo com variáveis sociodemográficas e de pré-natal. Resultados. Identificaram-se 754 casos de SC no período estudado (incidência média de 11,9 casos/1 000 nascidos vivos). A incidência foi mais elevada em jovens (10 a 19 anos; 20 a 24 anos), participantes de cor preta e naquelas com baixa escolaridade e sem pré-natal. Do total de mulheres, apenas 57,6% obtiveram o diagnóstico de sífilis durante o pré-natal. O tratamento foi inadequado em 87,7% das mulheres. Apenas 12,2% dos parceiros foram tratados. Houve tendência crescente do agravo (16%/ano), que atingiu 23,2 casos/1 000 nascidos vivos em 2016. O crescimento foi mais acentuado em adolescentes do sexo feminino (25,2%/ano), raça/cor parda (16,8%/ano), indivíduos com baixa escolaridade (57,1%/ano) e mulheres que realizaram pré-natal (17,3%/ano); e, no período de 2012 a 2016, em mulheres com informação ignorada para a cor da pele. Conclusões. As iniquidades sociais se destacaram na ocorrência de SC, com incidência crescente em jovens. É necessária a capacitação dos profissionais de saúde para o manejo da sífilis gestacional e uma atuação efetiva das políticas públicas sobre os determinantes sociais da sífilis.SimObjective. To describe the temporal distribution and epidemiologic characteristics of congenital syphilis (CS) cases in the city of Niterói, southeastern Brazil, from 2007 to 2016. Method. This descriptive time series analysis of the incidence of CS used data from the Notifiable Diseases Information System (SINAN) and the Live Birth Information System (SINASC). The sample included all notified cases. A probabilistic matching was performed between SINAN and SINASC data to recover ignored information. The time series was estimated using logarithmic regression according to sociodemographic and prenatal care variables. Results. There were 754 identified cases of CS in the study period (mean incidence: 11.9 cases/1 000 live births). The incidence was higher in younger women (10 to 19; 20 to 24 years) and in those with black skin, low schooling, and without prenatal care. Of the overall group, only 57.6% received a diagnosis of syphilis during prenatal care. Treatment was not adequate in 87,7%, and only 12.2% of partners were treated. SC incidence presented a growing trend of 16%/year, reaching 23.2 cases/1 000 living births in 2016. This growth was especially marked in female adolescents (25.2%/year), brown race/skin color (16.8%/year), women with low schooling (57.1%/year) and women who received prenatal care (17.3%/year); and, from 2012 to 2016, in women without information on skin color. Conclusions. Social inequalities were linked to CS in the present sample. Also, increasing CS incidence was detected in youth. Health care professionals must be trained to manage gestational syphilis, and public policies must effectively address the social determinants of this condition.Objetivo.

What do children aged 5 to 14 years die from in the state of Rio de Janeiro, Brazil? Trend analysis of the period 2000-2019

Abstract This study investigated the magnitude and trends of cause-specific mortality among children 5 to 14 years of age in the state of Rio de Janeiro (RJ) from 2000 to 2019. We performed an ecological study, using data from the Mortality Information System (MIS). We calculated mortality rates per 100,000 children by chapters, groups, and categories of causes of death (ICD-10). Trends were estimated by joinpoint regression. Mortality rates among children aged 10 to 14 years were higher than those among children 5 to 9. The five leading causes of death were the same in both age groups, but they ranked differently. The two leading ones were external causes and neoplasms (31% and 15% among children aged 5 to 9 years; 45% and 11% among children aged 10 to 14 years). Among children 5 to 9 years, the mortality trend showed an annual decline (8%) from 2011 to 2015. Among children aged 10 to 14 years, the annual decline was 1.3% from 2000 to 2019. Mortality due to external causes decreased in both age groups, except for the category “Assault by unspecified firearm” (boys, 10 to 14 years) and “Unspecified drowning and submersion” (boys, 5 to 9 years). Mortality caused by neoplasms remained steady in both age groups. Infectious and respiratory diseases decreased differently between the two groups. Most causes of death are preventable or treatable, indicating the need for health and intersectoral investments.</p

Effects of Moringa oleifera leaf meal on performance and carcass yield of broilers

This study evaluated the effects of including Moringa oleifera (moringa) leaf meal on performance, carcass yield and characteristics, and relative organ weights of broilers from 10 to 42 days of age. We distributed 420 male Cobb 500 chicks in a completely randomized design with five treatments and six replicates with 14 birds each. Treatments consisted of five experimental diets in which the moringa leaf meal was included at 0, 1.5, 3.0, 4.5, and 6.0% in the diets. The following performance variables were evaluated: weight gain, feed intake, and feed conversion; weights and yields of carcass, carcass traits, organs, and abdominal fat; and feet color. Significant differences between the treatment means were analyzed by Dunnett’s test. The meal inclusion levels did not affect performance, carcass characteristics and yield, or organs weight. However, feet pigmentation increased linearly, and abdominal fat was greater only at the 1.5% level when compared with the control group. Moringa leaf meal can be included in the diet of broilers from 10 to 42 days of age, up to the level of 6%, without compromising performance or carcass yield of these birds

Resposta do treinamento concorrente para pessoas com deficiência intelectual

The aim of the study was to evaluate the effects of a concurrent training program on overweight, obesity and improving functional autonomy in people with intellectual disability (ID). Six students with ID between the ages of 19 and 55 participated in the study. The period of intervention of the research occurred during 8 months, 2 for setting and 6 for training. The evaluation of overweight and obesity was performed by the analysis of the Body Mass Index (BMI) and the Hip Waist Ratio (WHR). The Functional Independence Scale and the Gross Motor Function Classification System (GMFCS) were evaluated for functional autonomy. For the muscle force training load used is between 50/60% of one repetition maximum resistance and cardiovascular training intensity was determined using the test 1600m. The results showed statistically significant improvements in the total GMFCS score in the upper and lower limbs of both genders (p <0.05). The results allow to conclude that the practice of the concurrent training improved the functional autonomy considering the general scope of people with intellectual disability.O objetivo do estudo foi avaliar os efeitos de um programa de treinamento concorrente acerca de sobrepeso, obesidade e melhoria da autonomia funcional em pessoas com deficiência intelectual (DI). Participaram do estudo 6 estudantes com DI com idade entre 19 e 55 anos. O estudo ocorreu durante 8 meses, sendo 2 para ambientação e 6 para o treinamento. A avaliação de sobrepeso e obesidade foi realizada pela análise do Índice de Massa Corporal (IMC) e da Relação Cintura Quadril (RCQ). A avaliação da autonomia funcional foi feita pela Escala de Independência Funcional e pelo Sistema de Classificação de Função Motora Grossa (GMFCS). Para o treinamento de força muscular, utilizaram-se cargas entre 50 e 60% de uma repetição máxima e para o treinamento de resistência cardiovascular a intensidade foi determinada por meio do teste de 1.600m. Os resultados apresentam melhorias estatisticamente significativas no escore total da escala GMFCS em membros superiores e inferiores de ambos os gêneros (p < 0,05). Os resultados possibilitam concluir que a prática do treinamento concorrente melhorou a autonomia funcional considerando o âmbito geral de pessoas com deficiência intelectual
