RESUMO
BACKGROUND: The Brazilian Amazon faces overlapping socio-environmental, sanitary, and climate challenges, and is a hotspot of concern due to projected increases in temperature and in the frequency of heat waves. Understanding the effects of extreme events on health is a central issue for developing climate policies focused on the population's health. OBJECTIVES: We investigated the effects of heat waves on mortality in the Brazilian Amazon, examining effect modification according to various heat wave definitions, population subgroups, and causes of death. METHODS: We included all 32 Amazonian municipalities with more than 100,000 inhabitants. The study period was from 2000 to 2018. We obtained mortality data from the Information Technology Department of the Brazilian Public Healthcare System, and meteorological data were derived from the ERA5-Land reanalysis dataset. Heat waves were defined according to their intensity (90th; 92.5th; 95th; 97.5th and 99th temperature percentiles) and duration (≥2, ≥3, and ≥4 days). In each city, we used a time-stratified case-crossover study to estimate the effects of each heat wave definition on mortality, according to population subgroup and cause of death. The lagged effects of heat waves were estimated using conditional Poisson regression combined with distributed lag non-linear models. Models were adjusted for specific humidity and public holidays. Risk ratios were pooled for the Brazilian Amazon using a univariate random-effects meta-analysis. RESULTS: The pooled relative risks (RR) for mortality from total non-external causes varied between 1.03 (95% CI: 1.01-1.06), for the less stringent heat wave definition, and 1.18 (95% CI: 1.04-1.33) for the more stringent definition. The mortality risk rose as the heat wave intensity increased, although the increase from 2 to 3, and 3-4 days was small. Although not statistically different, our results suggest a higher mortality risk for the elderly, this was also higher for women than men, and for cardiovascular causes than for non-external or respiratory ones. CONCLUSIONS: Heat waves were associated with a higher risk of mortality from non-external causes and cardiovascular diseases. Heat wave intensity played a more important role than duration in determining this risk. Suggestive evidence indicated that the elderly and women were more vulnerable to the effects of heat waves on mortality.

OBJECTIVE: To investigate the correlation between dispositional mindfulness, emotional regulation and perceived stress and to verify factors associated with dispositional mindfulness among nursing students. METHOD: A correlational, cross-sectional study with public undergraduate students. The following instruments were used: Mindful Attention Awareness Scale, Emotional Regulation Questionnaire and Perceived Stress Scale. Analyzes were performed using t tests, Pearson's correlation and multiple linear regression. RESULTS: The study included 330 students. There was no correlation between dispositional mindfulness and general emotional regulation score and/or perceived stress and a weak correlation with the emotional regulation dimension emotional suppression. Being in psychological treatment and psychoactive substance use were associated with decreased dispositional mindfulness. Age, sufficient sleep hours and emotional suppression were associated with an increase in this variable. CONCLUSION: There was a relationship between dispositional mindfulness only with emotional suppression, in addition to the connection of this variable with the perception of sufficient sleep hours, age, use of alcohol or psychoactive substances, undergoing psychological/psychiatric follow-up and emotional suppression.

The objective was to analyze the association of changes in pre-dialysis systolic and diastolic blood pressure with air temperature in a municipality in the Brazilian Pantanal, a tropical climate area. Longitudinal panel study, with analysis of mixed effects models of 133 hemodialysis patients in the city of Cáceres-Mato Grosso in 2014. Air temperature showed an inverse association with pre-dialysis systolic and diastolic blood pressure. With each increase of 1 °C in the mean air temperature, the pre-dialysis systolic blood pressure decreases -0.730mmHg (p ≤ 0.000) and the pre-dialysis diastolic blood pressure decreases -0.280mmHg (p ≤ 0.000). The estimated effect was greater for systolic blood pressure, but both pre-dialysis blood pressure measures are reduced with an increase in lag (up to two days), even when adjusted for relative air humidity. Air temperature is determinant for changes in pre-dialysis systolic and diastolic blood pressure in hemodialysis patients. The temperature effect was greater for systolic blood pressure than for diastolic blood pressure.
RESUMO
Introdução: Blastocystis sp. é o parasito mais comum encontrado nos estudos de prevalência de parasitas intestinais em diferentes populações. Objetivo: determinar a prevalência do parasita intestinal Blastocystis sp. em moradores da comunidade quilombola Distrito Nossa Senhora Aparecida do Chumbo localizada em uma área rural do Município de Poconé-MT. Método: Trata-se de um estudo epidemiológico descritivo e quantitativo que determinou a prevalência do parasita intestinal Blastocystis sp. que ocorreu nos meses de dezembro de 2021 a maio de 2022. A amostra final foi composta por 114 participantes. Na identificação das formas evolutivas dos parasitas intestinais nas amostras fecais foi empregado o método de Hoffman. As amostras foram analisadas com auxílio do microscópio óptico e as lâminas foram coradas com lugol, para identificação das formas evolutivas dos parasitos. Para análise descritiva foi realizado a frequência absoluta e percentual. Foram realizados cálculos para determinar a prevalência total de parasitos intestinais e a prevalência por tipo de parasitas. Resultados: A prevalência total foi de 75%, deste a maior ocorrência foi apresentada por Blastocystis sp. Conclusão: Sugerimos, que a alta prevalência deste parasito que tem por via de contaminação fecal- oral, esteja associada à falta de um saneamento adequado, bem como ao acesso da água de qualidade.
Introduction: Blastocystis sp. is the most common parasite found in studies of intestinal parasite prevalence in different populations. Objective: To determine the prevalence of the intestinal parasite Blastocystis sp. in residents of the quilombola community of Distrito Nossa Senhora Aparecida do Chumbo located in a rural area of the Municipality of Poconé-MT. Method: This is a descriptive and quantitative epidemiological study that determined the prevalence of the intestinal parasite Blastocystis sp. that occurred in the months from December 2021 to May 2022. The final sample consisted of 114 participants. The Hoffman method was used to identify the evolutionary forms of the intestinal parasites in the fecal samples. The samples were analyzed with the aid of an optical microscope and the slides were stained with lugol to identify the evolutive forms of the parasites. For descriptive analysis, absolute and percentage frequency was performed. Calculations were performed to determine the total prevalence of intestinal parasites and the prevalence by type of parasites. Results: The total prevalence was 75%, of this the highest occurrence was presented by Blastocystis sp. Conclusion: We suggest, that the high prevalence of this parasite that has a fecal-oral contamination route, is associated with the lack of proper sanitation, as well as access to quality water.

OBJECTIVE: To evaluate surveillance of contacts of new tuberculosis cases in the state of Mato Grosso from 1999 to 2004. METHODS: This was a descriptive epidemiological study based on data from the Tuberculosis Case Registry Database. The number of new tuberculosis cases, the number of contacts (estimated, investigated, and uninvestigated), and the tuberculosis incidence rate were analyzed by age bracket. The mean rate of contacts investigated for each case of tuberculosis by age bracket was calculated per year of study. The cases of pulmonary tuberculosis with and without contacts investigated were analyzed by sputum smear microscopy results. RESULTS: In 2004, there were 41.3 cases of tuberculosis per 100,000 inhabitants in the state of Mato Grosso. The south-central region presented the highest incidence rate (57 cases/100,000 inhabitants) and a 15% rate of contacts investigated. Among those younger than 15 years, 63 contacts (60.5%) were investigated, whereas among those aged 15 or older, 389 (8.9%) were investigated. In 1999, the mean rate of contacts investigated statewide was 0.02 (0.5%), and, in 2004, it reached 0.42 (10.5%). The percentage of contacts investigated was 40% higher among the contacts of contagious cases (OR = 1.4; 95% CI: 1.08-1.83). CONCLUSIONS: The percentage of contacts investigated is very low, principally among adults. The adoption of the standards for investigation of tuberculosis contacts proposed by the Brazilian National Ministry of Health Department of Health Surveillance has not ensured that this group at highest risk of developing active tuberculosis be given priority at health care facilities in the state of Mato Grosso.

OBJETIVO: Avaliar as ações de vigilância de contatos de casos novos de tuberculose em Mato Grosso no período de 1999 a 2004. MÉTODOS: Estudo epidemiológico descritivo baseado em dados do Sistema de Informação de Agravos de Notificação-Tuberculose. O número de casos novos de tuberculose, o número de contatos (estimados, examinados e não examinados) e a taxa de incidência de tuberculose foram analisados segundo a faixa etária. Calculou-se, por ano de estudo, a média de contatos examinados para cada caso de tuberculose segundo a faixa etária. Os casos de tuberculose pulmonar com e sem contatos examinados foram analisados segundo o resultado da baciloscopia. RESULTADOS: Em 2004, Mato Grosso apresentou 41,3 casos de tuberculose por 100 mil habitantes. A mesorregião centro-sul apresentou a maior taxa de incidência (57 casos/100 mil habitantes) e uma taxa de 15 por cento de contatos examinados. Entre os menores de 15 anos, examinaram-se 63 contatos (60,5 por cento), enquanto entre aqueles com 15 anos ou mais, examinaram-se 389 contatos (8,9 por cento). Em 1999, a média de contatos examinados em Mato Grosso foi de 0,02 (0,5 por cento), e, em 2004, ela alcançou 0,42 (10,5 por cento). O percentual de contatos examinados foi 40,0 por cento maior entre os contatos de casos bacilíferos (OR = 1,4; IC95 por cento: 1,08-1,83). CONCLUSÕES: O percentual de contatos examinados é muito baixo, principalmente entre os adultos. A normatização do exame de contatos de tuberculose pela Secretaria de Vigilância em Saúde do Ministério da Saúde não tem sido suficiente para garantir que esse grupo de maior risco de adoecimento seja priorizado pelos serviços de saúde de Mato Grosso.
