ABSTRACT

A incidência da dengue, doença viral transmitida pelo mosquito Aedes aegypti, vem crescendo em Porto Alegre ao longo dos anos, com recorde de casos registrados em 2022. Epidemias da doença parecem ocorrer de forma cíclica no município, com registros a cada três anos. Dada a influência de fatores climáticos no ciclo de vida do vetor, este trabalho buscou analisar a influência de determinantes meteorológicos na periodicidade de epidemias de dengue na capital gaúcha entre 2010 e 2022. Análises descritivas foram realizadas para averiguar o padrão dos indicadores climáticos e dos casos de dengue ao longo dos anos, ao passo que análises estatísticas foram feitas para avaliar a correlação entre os fatores climáticos e os casos autóctones registrados entre 2016 e 2022. Os resultados obtidos não apontaram padrões meteorológicos que se repetem a cada três anos e que poderiam explicar a ciclicidade observada. Ainda, não foram constatadas correlações entre temperatura, umidade e pluviosidade com casos autóctones de dengue no município, ao menos em nível quadrimestral. Para além destas análises, constatou-se expressivo aumento de casos em 2022, apesar dos esforços de controle desempenhados pelo poder público, o que aponta a necessidade de maior investimento em educação em saúde para a população.

The incidence of dengue, a viral disease transmitted by the Aedes aegypti mosquito, has been increasing in Porto Alegre over the years, with a record number of cases reported in 2022. Epidemics of the disease seem to occur cyclically in the city, with reports every three years. Given the influence of climatic factors on the vector's life cycle, this study aimed to analyze the influence of meteorological determinants on the periodicity of dengue epidemics in Porto Alegre between 2010 and 2022. Descriptive analyses were used to investigate the pattern of climatic indicators and dengue cases over the years, while statistical analyses were performed to evaluate the correlation between climatic factors and autochthonous cases registered between 2016 and 2022. The results did not point out meteorological patterns that repeat every three years and could explain the observed cyclicity. Furthermore, no correlations were found between temperature, humidity and rainfall and autochthonous dengue cases in the city, at least on a four-monthly basis. Beyond these analyses, a significant increase in dengue cases was observed in 2022, despite the efforts of the public authorities to control the disease, which highlights the need for greater investment in health education for the population.

ABSTRACT

BACKGROUND@#It is crucial to understand the seasonal variation of Metabolic Syndrome (MetS) for the detection and management of MetS. Previous studies have demonstrated the seasonal variations in MetS prevalence and its markers, but their methods are not robust. To clarify the concrete seasonal variations in the MetS prevalence and its markers, we utilized a powerful method called Seasonal Trend Decomposition Procedure based on LOESS (STL) and a big dataset of health checkups.@*METHODS@#A total of 1,819,214 records of health checkups (759,839 records for men and 1,059,375 records for women) between April 2012 and December 2017 were included in this study. We examined the seasonal variations in the MetS prevalence and its markers using 5 years and 9 months health checkup data and STL analysis. MetS markers consisted of waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), fasting plasma glucose (FPG).@*RESULTS@#We found that the MetS prevalence was high in winter and somewhat high in August. Among men, MetS prevalence was 2.64 ± 0.42 (mean ± SD) % higher in the highest month (January) than in the lowest month (June). Among women, MetS prevalence was 0.53 ± 0.24% higher in the highest month (January) than in the lowest month (June). Additionally, SBP, DBP, and HDL-C exhibited simple variations, being higher in winter and lower in summer, while WC, TG, and FPG displayed more complex variations.@*CONCLUSIONS@#This finding, complex seasonal variations of MetS prevalence, WC, TG, and FPG, could not be derived from previous studies using just the mean values in spring, summer, autumn and winter or the cosinor analysis. More attention should be paid to factors affecting seasonal variations of central obesity, dyslipidemia and insulin resistance.

ABSTRACT

Inner Mongolia autonomous region of China and Mongolia are the primary regions where Chinese and Mongolian medicine and its medicinal plant resources are distributed. In this study, 133 families, 586 genera, and 1 497 species of medicinal plants in Inner Mongolia as well as 62 families, 261 genera, and 467 species of medicinal plants in Mongolia were collected through field investigation, specimen collection and identification, and literature research. And the species, geographic distribution, and influencing factors of the above medicinal plants were analyzed. The results revealed that there were more plant species utilized for medicinal reasons in Inner Mongolia than in Mongolia. Hotspots emerged in Hulunbuir, Chifeng, and Tongliao of Inner Mongolia, while there were several hotspots in Eastern province, Sukhbaatar province, Gobi Altai province, Bayankhongor province, Middle Gobi province, Kobdo province, South Gobi province, and Central province of Mongolia. The interplay of elevation and climate made a non-significant overall contribution to the diversity of plant types in Inner Mongolia and Mongolia. The contribution of each factor increased significantly when the vegetation types of Inner Mongolia and Mongolia were broadly divided into forest, grassland and desert. Thus, the distribution of medicinal plant resources and vegetation cover were jointly influenced by a variety of natural factors such as topography, climate and interactions between species, and these factors contributed to and constrained each other. This study provided reference for sustainable development and rational exploitation of medicinal plant resources in future.

ABSTRACT

Human bocavirus is a novel pathogen first detected in respiratory tract samples in 2005. People of different ages can be infected by human bocavirus. Children are the susceptible population, especially the infants aged from 6-24 months old. The epidemic season varies in different regions due to the differences in climate and geographical location, and it mainly occurs in autumn and winter. It's demonstrated that human bocavirus-1 is closely related to respiratory system diseases and even causes life-threatening critical illness. Also, the severity of symptom is positively correlated with viral load. Co-infections between human bocavirus-1 and other viruses often present high frequency occurrence. Human bocavirus-1 interferes immune function of host by inhibiting interferon secrete pathway. Currently, it remains limited knowledge and understanding of the roles of human bocavirus 2-4 in diseases, but the gastrointestinal diseases should be paid more attention. Detection of human bocavirus DNA by traditional polymerase chain reaction (PCR) assay shouldn't be regarded as conclusive diagnostic basis. Instead, combined with mRNA and specific antigen detection, it is beneficial to improve the accuracy of diagnosis. Till now, the knowledge of human bocavirus remains poorly studied, which is deserved to further progress.

ABSTRACT

ABSTRACT Introduction A tennis match may last up to four hours with long intervals between moves of medium to high exercise intensity for 10 minutes and aerobic characteristic that requires specific sources of energy. Inappropriate diets can negatively impact sports performance and delay the recovery phase. Fortified wheat germ protein powder has the supplementation characteristics required in aerobic activities, although there are no practical studies on its impacts on the work performance of female tennis athletes. Objective Explore the influence of two weeks of training in a warm environment combined with nutritional intervention on the performance of female tennis players. Methods It was observed by testing the immunological indices of elite female tennis players while training their changes and their effects on nutritional intervention. Results The increase in serum CK activity was closely related to the amount of exercise. Many studies have shown that serum CK activity increased significantly after strenuous exercise, and the serum CK value of subjects in the test group was significantly lower than that of the control group, showing better adaptability to exercise. Compared with before the nutritional intervention, the athletes' weight decreased slightly, and the body fat percentage decreased significantly after the nutritional intervention. Compared with before nutritional intervention, sugar and salt supplements in athletes were significantly increased (P<0.05). Sweating rate, hydration rate, and hydration/sudden rate were also significantly increased (P<0.05). Conclusion Strengthening wheat germ protein supplementation may improve the nutritional albumin level in female tennis players, manifested in blood levels and immune function performance. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.


RESUMO Introdução Partidas de tênis podem durar até quatro horas com intervalos longos entre jogadas de intensidade de exercício média a alta por 10 minutos, características aeróbicas que requerem fontes específicas de energia. Dietas inapropriadas podem impactar negativamente o desempenho esportivo e retardar o período de recuperação. O pó de proteína de germe de trigo fortificado apresenta as características de suplementação requeridas nas atividades aeróbicas, embora não haja estudos práticos sobre seus impactos no desempenho profissional de atletas do tênis feminino. Objetivo Explorar a influência no treinamento de duas semanas em ambiente quente combinado com a intervenção nutricional sobre o desempenho das atletas tenistas. Métodos Ao testar os índices imunológicos das tenistas de elite durante o treinamento, observamos suas mudanças e seus efeitos na intervenção nutricional. Resultados O aumento da atividade de CK sérico esteve intimamente relacionado à quantidade de exercício. Muitos estudos mostraram que a atividade do soro CK aumentou significativamente após o exercício extenuante, e o valor sérico CK dos sujeitos no grupo de teste foi significativamente menor do que o do grupo controle, mostrando melhor adaptabilidade ao exercício. Em comparação com antes da intervenção nutricional, o peso dos atletas diminuiu ligeiramente e o percentual de gordura corporal diminuiu significativamente após a intervenção nutricional. Em comparação com antes da intervenção nutricional, os suplementos de açúcar e sal em atletas foram significativamente incrementados (P<0,05). A taxa de sudorese, a taxa de hidratação e a taxa de hidratação/sudorese também aumentaram significativamente (P<0,05). Conclusão Fortalecer a suplementação com proteína de germe de trigo pode melhorar o nível nutricional de albumina nas tenistas, manifestadamente nos níveis sanguíneos e desempenho da função imunológica. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

ABSTRACT

A pandemia de COVID-19 deu ao mundo uma imagem clara do que é uma crise multidimensional em escala planetária, revelando o papel central que ocupa o setor de saúde e as profundas desigualdades no acesso aos cuidados em saúde que existem entre os diferentes países, e dentro de cada um deles. Melhorar os efeitos ambientais do setor e reduzir as emissões de gases de efeito estufa pode não apenas melhorar a saúde de todos, mas também reduzir os custos com os cuidados em saúde. O setor de saúde de cada país libera direta e indiretamente gases de efeito estufa ao fornecer seus serviços e ao comprar produtos, serviços e tecnologias em uma cadeia de fornecimento de carbono intensivo. Educar os profissionais de saúde mais profundamente sobre os efeitos das mudanças climáticas pode levar a práticas clínicas mais sustentáveis, melhorando os resultados para os pacientes e fornecendo um impulso substancial para aumentar os esforços para reduzir as emissões de carbono. O setor da saúde deve assumir a responsabilidade por sua pegada climática respondendo à crescente emergência climática, não apenas prestando assistência aos doentes, feridos ou moribundos como resultado da crise climática e suas causas, mas também fazendo a prevenção primária e reduzindo drasticamente suas próprias emissões.


The COVID-19 pandemic has painted a clear picture of what a multidimensional planetary crisis is, revealing the central role played by the health sector and the deep inequalities in access to health care that exist between and within each country. Decreasing the environmental effects of the health sector and reducing greenhouse gas emission may not only improve people's health, but also reduce health care costs. The health care sectors around the world directly and indirectly release greenhouse gases by providing their services and purchasing products, services, and technologies within a carbon-intensive supply chain. Further educating health care professionals about the effects of climate change may lead to more sustainable clinical practices, improving patient outcomes and providing substantial impetus to increased efforts to reduce carbon emission. The health sector must take responsibility for its climate footprint by responding to the growing climate emergency not only by assisting the sick, injured, or dying from the climate crisis, but also by doing primary prevention and drastically reducing its own carbon emission.

ABSTRACT

Paeonia lactiflora is an important medicinal resource in China. It is of great significance for the protection and cultivation of P. lactiflora resources to find the suitable habitats. The study was based on the information of 98 distribution sites and the data of 20 current environmental factors of wild P. lactiflora in China. According to the correlation and importance of environmental factors, we selected the main environmental factors affecting the potential suitable habitats. Then, BCC-CSM2-MR model was employed to predict the distribution range and center change of potential suitable habitat of wild P. lactiflora in the climate scenarios of SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5 during 2021-2100. The ensemble model combined with GBM, GLM, MaxEnt, and RF showed improved prediction accuracy, with TSS=0.85 and AUC=0.95. Among the 20 environmental factors, annual mean temperature, monthly mean diurnal range of temperature, temperature seasonality, mean temperature of the warmest quarter, precipitation of the wettest month, precipitation seasonality, precipitation of the driest quarter, and elevation were the main factors that affected the suitable habitat distribution of P. lactiflora. At present, the potential suitable habitats of wild P. lactiflora is mainly distributed in Inner Mongolia, Heilongjiang, Jilin, Liaoning, Hebei, Beijing, Shaanxi, Shanxi, Shandong, Gansu, Xinjiang, Tibet, and Ningxia, and concentrated in the northeastern Inner Mongolia, central Heilongjiang, and northern Jilin. Under future climate conditions, the highly sui-table area of wild P. lactiflora will shrink, and the potential suitable habitat will mainly be lost to different degrees. However, in the SSP5-8.5 scenario, the low suitable area of wild P. lactiflora will partially increase in the highlands and mountains in western China including Xinjiang, Tibet, and Qinghai during 2061-2100. The distribution center of wild P. lactiflora migrated first to the northeast and then to the southwest. The total suitable habitats were stable and kept in the high-latitude zones. The prediction of the potential geo-graphical distribution of P. lactiflora is of great significance to the habitat protection and standardized cultivation of this plant in the future.

ABSTRACT

Existe uma limitação de trabalhos na literatura acerca da sazonalidade da tuberculose (TB) no hemisfério sul, o que torna necessário o preenchimento dessa lacuna de conhecimento para a região. O estudo objetiva analisar se existe sazonalidade da incidência de TB nas capitais brasileiras do Brasil e no Distrito Federal, por meio de um estudo ecológico de série temporal (2001-2019) dos casos da doença. Utilizou-se a base de 516.524 casos de TB do Ministério da Saúde. As capitais e o Distrito Federal foram distribuídos em cinco grupos, com base em indicadores sociais, carga da doença e classificação climática de Koppen. Avaliou-se a variação sazonal das notificações de TB e a amplitude sazonal por grupo. Identificou-se a presença da sazonalidade da TB no Brasil ao nível de significância de 1% em todos os grupos de capitais (teste de estabilidade assumida e Krusall-Wallis, p < 0,01) e, no teste combinado de sazonalidade, os grupos A, D e E de capitais mostraram presença de sazonalidade; e, provavelmente presentes, os grupos B e C. Os achados mostraram que é um desafio levantar os fatores sazonais subjacentes à sazonalidade da TB nas regiões tropicais do Hemisfério Sul: o clima pode não ser o fator subjacente mais relevante encontrado na sazonalidade da TB, mas sim a oferta e/ou procura por serviços de saúde.


The literature has few studies on the seasonality of tuberculosis (TB) in the southern hemisphere, entailing the fill of this knowledge gap. This study aims to analyze whether TB incidence in Brazilian capitals and the Federal District is seasonal. This is an ecological study of a time series (2001-2019) of TB cases, conducted with 26 capitals and the Federal District. The Ministry of Health database, with 516,524 TB cases, was used. Capitals and the Federal District were divided into five groups based on social indicators, disease burden, and the Koppen climate classification. The seasonal variation of TB notifications and group amplitude were evaluated. We found TB seasonality in Brazil with a 1% significance in all capital groups (Stability assumption and Krusall-Wallis tests, p < 0.01). In the combined seasonality test, capital groups A, D, and E showed seasonality, whereas groups B and C, its probability. Our findings showed that health service supply and/or demand - rather than climate - may be the most relevant underlying factor in TB seasonality. It is challenging to raise the other seasonal factors underlying TB seasonality in tropical regions in the Southern Hemisphere.


Son limitados los estudios que tratan de la estacionalidad de la tuberculosis (TB) en el hemisferio Sur, por lo que se hace necesario llenar esta laguna. Este estudio tiene como objetivo analizar si existe una estacionalidad en la incidencia de TB en las capitales brasileñas y en el Distrito Federal, Brasil. Estudio ecológico de series de tiempo (2001-2019) de casos de TB, realizado en 26 capitales brasileñas y el Distrito Federal. Se utilizó una base de datos con 516.524 casos de TB del Ministerio de Salud. Las capitales y el Distrito Federal se dividieron en cinco grupos, con base en indicadores sociales, carga de enfermedad y clasificación climática de Koppen. Se evaluaron la variación estacional de las notificaciones de TB y la amplitud estacional por grupo. La presencia de estacionalidad de la TB en Brasil fue identificada con un nivel de significación del 1% en todos los grupos de capitales (prueba de estabilidad supuesta y Kruskal-Wallis, p < 0,01), en la prueba de estacionalidad combinada, los grupos A, D y E de las capitales tuvieron la presencia de estacionalidad; y también es probable que haya estado presente en los grupos B y C. Los hallazgos demostraron que el clima puede no ser el factor subyacente más relevante encontrado en la estacionalidad de la TB, pero sí la oferta y/o demanda de servicios de salud, lo que muestra que es un desafío plantear los demás factores estacionales subyacentes a la estacionalidad de la TB en las regiones tropicales del Hemisferio Sur.

ABSTRACT

Resumen Introducción: Los estudios dendrocronológicos en México se han basado principalmente en las coníferas, mientras que las especies de madera dura han sido poco estudiadas. Este ha sido el caso del género Quercus, con una alta diversidad taxonómica en el país pero que no ha sido estudiado con fines dendrocronológicos, a pesar de los valores ecológicos y económicos de sus especies. Objetivo: En la presente investigación se determinó el potencial dendroclimático de Quercus sideroxyla en el noroeste de México, y su relación con variables climáticas como precipitación y temperatura. Métodos: La investigación se desarrolló en el estado de Durango en el ejido Chavarría Viejo en las coordenadas (23º43' N & 105º33' W), se recolectaron muestras de 5 a 7 cm en dos sitios bajo aprovechamiento forestal y se procesaron mediante técnicas dendrocronológicas convencionales. Resultados: Se desarrolló una cronología de ancho de anillo total, la cual se compuso por 30 muestras de 16 árboles para el período de 1917 a 2018 (101 años). Se obtuvieron valores de intercorrelación entre series de 0.43, de sensibilidad media de 0.36, relación señal-ruido de 3.53 y autocorrelación de primer orden (0.58). En cuanto a la relación clima-crecimiento, los valores de índice de ancho de anillo se correlacionaron con datos de la estación climática más cercana al sitio de estudio; donde la precipitación invierno-primavera (enero-mayo) fue la variable de mayor influencia en el crecimiento de la especie. Conclusiones: Con base en los parámetros dendrocronológicos se demuestra el alto potencial de la especie para ser empleada en estudios dendroclimáticos en la región, la respuesta de la especie a la precipitación es similar al de las coníferas con las que cohabita.


Abstract Introduction: Dendrochronological studies in Mexico have been mainly based on conifers, while hardwood species have been little studied. This has been the case of the genus Quercus, which has a high taxonomic diversity in the country but has not been previously studied for dendrochronological issues, despite the ecological and economic values of oak species. Objective: In the present investigation, the dendroclimatic potential of Quercus sideroxyla in Northwestern Mexico was determined, as well as its relationship with climatic variables such as precipitation and temperature. Methods: The research was carried out in the state of Durango, Chavarría Viejo with coordinates (23º43' N & -105º33' W). Samples of 5 cm to 7cm were collected in two sites under forest exploitation and processed by conventional dendrochronological techniques. Results: A chronology of total ring width was developed, which was composed of 30 samples from 16 trees for the period from 1917 to 2018 (101 years). Inter-series intercorrelation values of 0.43, mean sensitivity of 0.36, signal-to-noise ratio of 3.53 and first-order autocorrelation (0.58) were obtained. Regarding the climate-growth relationship, the ring width index values were correlated with data from the climatic station nearest to the study site, where winter-spring precipitation (January-May) was the variable with the greatest influence on the growth of the species. Conclusions: Based on the dendrochronological parameters, the high potential of the species that were used in dendroclimatic studies in the region has demonstrated that the response of the species to precipitation is similar to that of the conifers with which the Quercus sideroxyla shares its habitat with.

ABSTRACT

The objective of this study was to evaluate the spatial distribution of purebred Bos taurus taurus bovine breeds raised in Brazil in association with climatic, physical and socioeconomic variables. The breeds Aberdeen Angus, Ayrshire, Braford, Brangus, Charolais, Devon, Flemish, Hereford, Pinzgauer, Shorthorn and Simental were classified according to their aptitude (milk, meat or dual-purpose). They were spatialized according to their aptitude using state and municipal information. The milk breeds were found in the states of Rio Grande do Sul and Santa Catarina, while the dual-purpose breeds were found in Minas Gerais and Rio Grande do Sul states and the beef breeds were concentrated in the southern region. Only the Aberdeen Angus meat breed showed higher dispersion in other regions. Meat and dual-purpose breeds tended to be raised in regions with lower maximum temperature, average temperature, thermal amplitude and temperature-humidity index. Dual-purpose breeds were found in municipalities with high humidity and altitude, but with a low gross domestic product, little technical guidance received from cooperatives and the government, low control of diseases and parasites, as well as low use of pasture rotation systems. The spatial distribution of Brazilian bovine taurine breeds, regardless of aptitude, was related to climatic, physical and socioeconomic factors.(AU)


O objetivo deste estudo foi avaliar a distribuição espacial de raças bovinas puras Bos taurus taurus criadas no Brasil, associadas a variáveis climáticas, físicas e socioeconômicas. As raças Aberdeen Angus, Ayrshire, Braford, Brangus, Charolês, Devon, Flamenga, Hereford, Pinzgauer, Shorthorn e Simental foram classificadas de acordo com sua aptidão (leite, carne ou duplo-propósito). Elas foram espacializadas de acordo com sua aptidão a partir de informações estaduais e municipais. As raças leiteiras foram encontradas nos estados do Rio Grande do Sul e de Santa Catarina, enquanto as raças de duplo-propósito foram encontradas nos estados de Minas Gerais e Rio Grande do Sul, e as raças de carne concentraram-se na região Sul. Apenas a raça de carne Aberdeen Angus apresentou maior dispersão nas demais regiões. As raças de carne e de duplo-propósito tendem a ser criadas em regiões com menores temperatura máxima, temperatura média, amplitude térmica e índice de temperatura e umidade. As raças de duplo-propósito foram encontradas em municípios com alta umidade e altitude, mas com baixo produto interno bruto, pouca orientação técnica recebida de cooperativas e do governo, baixo controle de doenças e de parasitas e baixo uso de sistema de rotação de pastagens. A distribuição espacial das raças taurinas bovinas brasileiras, independentemente da aptidão, foi relacionada a fatores climáticos, físicos e socioeconômicos.(AU)

ABSTRACT

Introducción: Aedes spp. y la dinámica del virus del dengue está altamente influenciada por factores ambientales. Una relación detallada entre el clima y la enfermedad en los períodos inter e intra-epidémicos podrían beneficiar la vigilancia del dengue para optimizar la preparación y las políticas adecuadas de control de vectores. Métodos: se analizaron los informes de casos de dengue y las variables climáticas en Santo Domingo, República Dominicana, para determinar la correlación del período 2012- 2018 y los diferentes tiempos de retraso. Se llevó a cabo un análisis de regresión de dichas variables para comprender mejor las relaciones entre las tasas de incidencia del dengue y los cambios climáticos. Resultados: durante los brotes epidémicos, la temperatura (r = 0.73, p <0.001) y la humedad relativa (r = -0.2, p = 0.009) se correlacionan significativamente con la incidencia del dengue con un retraso de 9 semanas, el análisis de regresión muestra que la temperatura media (b = 62.401, p < 0.001), precipitación (b = 2.810, p <0.001) y humedad relativa (b = -5.462, p = 0.025) fueron predictores significativos. Durante los períodos inter-epidémico, la temperatura (r = 0.23, p <0.001) tuvo una correlación significativa con la incidencia del dengue con un retraso de 7 semanas, la humedad relativa (b = 1.454, p <0.05) y la temperatura media (b = 5.14, p <0.01) son predictores significativos de la cantidad de casos de dengue. La precipitación no se correlacionó significativamente con la incidencia del dengue. Conclusiones: existe una relación no lineal entre los factores climáticos y la incidencia del dengue. La infección por dengue depende del clima, y la temperatura parece jugar un papel importante en los factores climáticos.


Introduction: Aedes spp. and Dengue Virus dynamics are highly influenced by environmental factors. A detailed relationship between climate and disease in inter and intra-epidemic periods may benefit dengue surveillance, preparedness, and adequate vector control policies. Methods: Dengue case reports and climatic variables in Santo Domingo, Dominican Republic, were analyzed for climate variables correlation from the period 2012-2018 and varying lag times. Regression analysis of climatic variables was carried out to better understand significant correlations between dengue incidence rates and changes in climate. Results: During epidemic outbreaks, temperature (r = 0.73, p < 0.001) and relative humidity (r = -0.22, p = 0.009) demonstrated a significant correlation with dengue incidence. Our regression analysis demonstrates an increase 62.4 cases for each degree Celsius increased with a 9-week-lag. Regression analysis also demonstrated mean temperature (b= 62.401, p < 0.001), precipitation (b = 2.810, p < 0.001), and relative humidity (b = -5.462, p = 0.025) to be significant predictors. During inter-epidemic periods, temperature (r = 0.23, p < 0.001) had a significant correlation with dengue incidence with a 7-week-lag, which demonstrates that relative humidity (b = 1.454, p < 0.05), and mean temperature (b = 5.14, p < 0.01) are significant predictors of the quantity of dengue cases. Precipitation did not significantly correlate with dengue incidence. Conclusions: A non-linear relationship between climatic factors and dengue incidence exists in the Dominican Republic. Dengue infection is climate-dependent and temperature seems to play a significant role in climatic factors

INTRODUCTION: Varicella is a vaccine-preventable disease with marked seasonality. Few studies incorporate climatic variables to understand the epidemiological characteristics of this disease. The aim was to evaluate the relationship between varicella incidence and climatic variables in Tucumán (a province with temperate subtropical climate) during 2005-2019. METHODS: The relationship in pre- (2005-2014) and post-vaccination (2015-2019) periods was analyzed, identifying the associated climatic variables and the cut-off point where the risk of transmission increased. An observational ecological study was carried out with secondary data sources. R software was used. The information was split into three time series: 2005-2009, 2010-2014 and 2015-2019. For each period, a description of the time series was performed and generalized additive models (GAMs) were built using a negative binomial distribution. RESULTS: A seasonal behavior was observed, with peak incidence during spring in all periods. In the post-vaccination period, the peak occurred later (epidemiological week [EW] 46) than in the pre-vaccination periods (EW 43 and 42). Maximum temperature and relative humidity were associated during the first two periods, while minimum temperature, wind and thermal amplitude were associated in the third one. DISCUSSION: This study helped establish the relationship between climatic variables and varicella in Tucumán.

ABSTRACT

BACKGROUND@#For the reason that many studies have been inconclusive on the effect of humidity on respiratory disease, we examined the association between absolute humidity and respiratory disease mortality and quantified the mortality burden due to non-optimal absolute humidity in Guangzhou, China.@*METHODS@#Daily respiratory disease mortality including total 42,440 deaths from 1 February 2013 to 31 December 2018 and meteorological data of the same period in Guangzhou City were collected. The distributed lag non-linear model was used to determine the optimal absolute humidity of death and discuss their non-linear lagged effects. Attributable fraction and population attributable mortality were calculated based on the optimal absolute humidity, defined as the minimum mortality absolute humidity.@*RESULTS@#The association between absolute humidity and total respiratory disease mortality showed an M-shaped non-linear curve. In total, 21.57% (95% CI 14.20 ~ 27.75%) of respiratory disease mortality (9154 deaths) was attributable to non-optimum absolute humidity. The attributable fractions due to high absolute humidity were 13.49% (95% CI 9.56 ~ 16.98%), while mortality burden of low absolute humidity were 8.08% (95% CI 0.89 ~ 13.93%), respectively. Extreme dry and moist absolute humidity accounted for total respiratory disease mortality fraction of 0.87% (95% CI - 0.09 ~ 1.58%) and 0.91% (95% CI 0.25 ~ 1.39%), respectively. There was no significant gender and age difference in the burden of attributable risk due to absolute humidity.@*CONCLUSIONS@#Our study showed that both high and low absolute humidity are responsible for considerable respiratory disease mortality burden, the component attributed to the high absolute humidity effect is greater. Our results may have important implications for the development of public health measures to reduce respiratory disease mortality.

ABSTRACT

This paper explored the ecologically suitable areas for growing Scutellaria baicalensis using Geographic Information System for Global Medicinal Plants(GMPGIS), to figure out the resource distribution of S. baicalensis worldwide and provide a scientific basis for its scientific introduction. A total of 349 S. baicalensis sampling sites were selected all over the world for GMPGIS-based analy-sis of the ecologically suitable areas with six ecological factors including annual average temperature, average temperature during the coldest season, average temperature during the warmest season, average annual precipitation, average annual relative humidity, and annual average illumination and soil type as the ecological indexes. The results demonstrated that the ecologically suitable areas for growing S. baicalensis were mostly located in the Northern hemisphere, and the suitable areas in the United States, China, and Russia accounted for 19.25%, 18.66%, and 13.15% of the total area worldwide, respectively. In China, the Inner Mongolia, Heilongjiang province, and Yunnan province occupied the largest proportions of the total area, namely 14.28%, 8.72%, and 6.18%, respectively. As revealed by ecological factors of each sampling site, S. baicalensis was resistant to low temperature but not to high temperature. The adaptive range of average annual precipitation is narrower than that of average annual air humidity. The suitable soils were mainly inceptisol, alfisol, and fluvisol. High temperature and rainy climate or excessively high soil bulk density was not conducive to the growth of S. baicalensis. The adoption of GMPGIS enabled to obtain areas with the greatest ecological similarity for S. baicalensis, which were reliable data supporting the exploration of resource distribution and reasonable introduction of S. baicalensis.

ABSTRACT

Background: Although scorpionism is recorded worldwide, some regions such as Iran present a higher incidence. Due to the great prevalence of scorpion stings in Khuzestan province, southwestern Iran, the present study examined the relationship between different climate parameters and the scorpion sting rate in this area from April 2010 to March 2015. Methods: In this cross-sectional descriptive-analytical study, we considered all scorpion sting cases recorded in the Department of Infectious Diseases, Ahvaz Jundishapur University of Medical Sciences. Data were analyzed using statistics, frequency distribution and Pearson's correlation coefficient. Results: A total of 104,197 cases of scorpion stings was recorded from 2010 to 2015. The cumulative incidence of scorpion sting was 2.23%. The spatial distribution of scorpion stings showed that most cases occurred in the Dehdez district (4,504 scorpion stings/100,000 inhabitants) and the Masjed Soleyman county (4,069 scorpion stings/100,000 inhabitants). A significant association was found between climate factors (temperature, evaporation rate, sunshine duration, humidity, and precipitation) and the scorpion sting rate. An increase in rainfall and humidity coincided with a reduction in scorpion stings whereas an increase in temperature, evaporation, and sunshine duration was accompanied by a growth of scorpion stings. No significant correlation was found between wind velocity/direction and the incidence rate of stings. Moreover, the seasonal peak incidence of scorpion stings was recorded in summer (an average of 8,838 cases) and the lowest incidence was recorded during winter (an average of 1,286 cases). The annual trend of scorpion sting cases decreased during the period from 2010 to 2015. Conclusion: Climate variables can be a good index for predicting the incidence of scorpion stings in endemic regions. Since they occur mostly in the hot season, designing preventive measures in the counties and districts with a high incidence of scorpion stings such as Dehdez and Masjed Soleyman can minimize mortality and other burdens.(AU)

ABSTRACT

In this eight-year retrospective study, we evaluated the associations between climatic variations and the biological rhythms in plasma lipids and lipoproteins in a large population of Campinas, São Paulo state, Brazil, as well as temporal changes of outcomes of cardiovascular hospitalizations. Climatic variables were obtained at the Center for Meteorological and Climatic Research Applied to Agriculture (University of Campinas - Unicamp, Brazil). The plasma lipid databases surveyed were from 27,543 individuals who had their lipid profiles assessed at the state university referral hospital in Campinas (Unicamp). The frequency of hospitalizations was obtained from the Brazilian Public Health database (DATASUS). Temporal statistical analyses were performed using the methods Cosinor or Friedman (ARIMA) and the temporal series were compared by cross-correlation functions. In normolipidemic cases (n=11,892), significantly different rhythmicity was observed in low-density lipoprotein (LDL)- and high-density lipoprotein (HDL)-cholesterol (C) both higher in winter and lower in summer. Dyslipidemia (n=15,651) increased the number and amplitude of lipid rhythms: LDL-C and HDL-C were higher in winter and lower in summer, and the opposite occurred with triglycerides. The number of hospitalizations showed maximum and minimum frequencies in winter and in summer, respectively. A coincident rhythmicity was observed of lower temperature and humidity rates with higher plasma LDL-C, and their temporal series were inversely cross-correlated. This study shows for the first time that variations of temperature, humidity, and daylight length were strongly associated with LDL-C and HDL-C seasonality, but moderately to lowly associated with rhythmicity of atherosclerotic outcomes. It also indicates unfavorable cardiovascular-related changes during wintertime.

ABSTRACT

ABSTRACT BACKGROUND: Dengue is an arbovirus that has caused serious problem in Brazil, putting the public health system under severe stress. Understanding its incidence and spatial distribution is essential for disease control and prevention. OBJECTIVE: To perform an analysis on dengue incidence and spatial distribution in a medium-sized, cool-climate and high-altitude city. DESIGN AND SETTING: Ecological study carried out in a public institution in the city of Garanhuns, Pernambuco, Brazil. METHODS: Secondary data provided by specific agencies in each area were used for spatial analysis and elaboration of kernel maps, incidence calculations, correlations and percentages of dengue occurrence. The Geocentric Reference System for the Americas (Sistema de Referência Geocêntrico para as Américas, SIRGAS), 2000, was the software of choice. RESULTS: The incidence rates were calculated per 100,000 inhabitants. Between 2010 and 2019, there were 6,504 cases and the incidence was 474.92. From 2010 to 2014, the incidence was 161.46 for a total of 1,069 cases. The highest incidence occurred in the period from 2015 to 2019: out of a total of 5,435 cases, the incidence was 748.65, representing an increase of 485.97%. Population density and the interaction between two climatic factors, i.e. atypical temperature above 31 °C and relative humidity above 31.4%, contributed to the peak incidence of dengue, although these variables were not statistically significant (P > 0.05). CONCLUSION: The dengue incidence levels and spatial distribution reflected virus and vector adjustment to the local climate. However, there was no correlation between climatic factors and occurrences of dengue in this city.

ABSTRACT

Introduction: Triatoma recurva is a Trypanosoma cruzi vector whose distribution and biological development are determined by factors that may influence the transmission of trypanosomiasis to humans. Objective: To identify the potential spatial distribution of Triatoma recurve, as well as social factors determining its presence. Materials and methods: We used the MaxEnt software to construct ecological niche models while bioclimatic variables (WorldClim) were derived from the monthly values of temperature and precipitation to generate biologically significant variables. The resulting cartography was interpreted as suitable areas for T. recurva presence. Results: Our results showed that the precipitation during the driest month (Bio 14), the maximum temperature during the warmest month (Bio 5), and the altitude (Alt) and mean temperature during the driest quarter (Bio 9) determined T. recurva distribution area at a higher percentage evidencing its strong relationship with domestic and surrounding structures. Conclusions. This methodology can be used in other geographical contexts to locate potential sampling sites where these triatomines occur.


Introducción. Triatoma recurva es un vector de Trypanosoma cruzi cuya existencia y desarrollo biológico están determinados por factores que pueden influir en la transmisión de la tripanosomiasis a los seres humanos. Objetivo. Determinar una posible distribución espacial de Triatoma recurva y algunos factores sociales que determinan su presencia. Materiales y métodos. El modelado de nicho ecológico se hizo con el programa MaxEnt empleando las variables bioclimáticas (WorldClim) derivadas de los valores mensuales de temperatura y precipitación para generar variables biológicamente significativas. La cartografía resultante evidenció áreas adecuadas para la presencia de T. recurva. Resultados. Los resultados indicaron que la precipitación del mes más seco (Bio 14), la temperatura máxima del mes más cálido (Bio 5), y la altitud (Alt) y la temperatura media del trimestre más seco (Bio 9), determinaron en mayor porcentaje el área de distribución de T. recurva, observándose que es una especie con una acentuada relación con las estructuras domésticas y circundantes. Conclusión. Esta metodología puede emplearse en otros contextos geográficos para localizar posibles sitios de muestreo de estos triatominos.
