ABSTRACT

Reducing the mortality rate is of a great economic importance for pig farming. Therefore, it is necessary to define the conditions in the farrowing unit based on the performance of the piglets, and specific hematological and biochemical parameters. Therefore, the aim of this paper is to examine the importance of using skin moisture absorbent and its influence in preventing hypothermia, which causes great economic losses in pig production. The experiment was set up on a commercial farm in Serbia and included 92 pigs divided into the experimental and control group. Body temperature values, body weight and blood parameters were monitored. The obtained values indicate that there is a significantly positive correlation of body temperature change and body weight values, and body temperature showed a significantly higher increase in the experimental group compared to the control group. The results obtained from hematological and biochemical parameters provide a clearer picture of the metabolic processes in piglets in the farrowing unit and can be used to further improve pig production and as a complement to genetic enhancement.(AU)


A redução da taxa de mortalidade é de grande importância econômica para a suinocultura. Portanto, é necessário definir as condições na unidade de parto com base no desempenho dos leitões, para serem parâmetros hematológicos e bioquímicos específicos. Portanto, o objetivo deste trabalho é examinar a importância do uso de absorvente de umidade na pele e sua influência na prevenção da hipotermia, que causa grandes perdas econômicas na produção de suínos. A experiência foi montada em uma fazenda comercial na Sérvia, e incluiu 92 porcos divididos no grupo experimental e de controle. Os valores de temperatura corporal, pesos corporais e parâmetros sanguíneos foram monitorados. Os valores obtidos indicam que existe uma correlação significativamente positiva entre os valores da temperatura corporal e dos pesos corporais, e a temperatura corporal mostrou um aumento significativamente maior no grupo experimental em comparação com o grupo de controle. Os resultados obtidos a partir de parâmetros hematológicos e bioquímicos fornecem uma imagem mais clara dos processos metabólicos em leitões na unidade de parto e podem ser usados para melhorar ainda mais a produção de suínos e como um complemento ao melhoramento genético.(AU)

ABSTRACT

The objective of this study was to determine the scrotal thermographic profile and to verify the influence of temperature and humidity of the humid tropical climate on testicular temperature and seminal quality of Mangalarga Marchador stallions. The thermal profiles of the proximal, middle, and distal zones of the testicles and total surface temperature (TSTT) were recorded using an FLIR E60bx thermal imager. The average air temperature (°C) and relative humidity (%) were obtained 1, 5, 9, 33, and 66 days before semen collection and showed a mean value of 26.5±2.4 and 80.4±6.0 respectively. The scrotal surface temperature was close to 34°C and there was no variation with the age of the stallion, reproductive activity, and characteristics of the ejaculate (P>0.05). The only significant correlations obtained were between TSTT and minor defects (R = 0.41; P<0.05), between TSTT and total defects (R = 0.46; P<0.01), and between TSTT and percentage of morphologically normal sperm (R = -0.46; P<0.05). It was concluded that the Mangalarga Marchador stallions maintained the testicular temperature within favorable conditions for spermatogenesis, demonstrating the efficiency of testicular thermoregulation mechanisms in the Atlantic Forest biome.


O objetivo deste estudo foi determinar o perfil termográfico escrotal e verificar a influência da temperatura e da umidade do clima tropical úmido na temperatura testicular e na qualidade seminal de garanhões Mangalarga Marchador. Os perfis térmicos das zonas proximal, média e distal dos testículos e a temperatura da superfície total (TSTT) foram registrados usando-se um termovisor FLIR E60bx. A temperatura média do ar (° C) e a umidade relativa (%) foram obtidas um, cinco, nove, 33 e 66 dias antes da coleta de sêmen e apresentaram valor médio de 26,5 ± 2,4 e 80,4 ± 6,0, respectivamente. A temperatura da superfície escrotal foi próxima a 34°C, e não houve variação com a idade do garanhão, a atividade reprodutiva e as características do ejaculado (P>0,05). As únicas correlações significativas obtidas foram entre TSTT e defeitos menores (R=0,41; P<0,05), entre TSTT e defeitos totais (R=0,46; P<0,01), e entre TSTT e porcentagem de espermatozoides morfologicamente normais (R=-0,46; P<0,05). Concluiu-se que os garanhões Mangalarga Marchador mantiveram a temperatura testicular dentro de condições favoráveis para a espermatogênese, demonstrando a eficiência dos mecanismos de termorregulação testicular no bioma Mata Atlântica.

ABSTRACT

ABSTRACT Objective Humidity and temperature are fundamental for the balance in the life cycle of living beings and, consequently, for maintaining the well-being of the human population and reducing the prevalence of infectious diseases. Thus, in order to mitigate the impact of climate change, especially in the period when humidity is not the ideal, it is necessary to adopt some assistance measures. The present experimental study aims to elucidate what would be the recommended option to improve the quality of life of the human being and to clarify which resources (air humidifier, bucket of water or wet towel) will be effective to improve the humidity of the air in times of drought and low moisture. Methods The experimental study was carried out with INKBIRD hygrometers allowing the analysis of the variation of air humidity throughout the day. Three forms of treatment were established: humidifier, wet towel and bucket of water. In each room, two hygrometers were placed equidistant from the occupant of the room and their respective treatment that varied between 1m and 2m away from the headboard indoor each room. In addition, two environments were used as controls, one being an external environment and the other an internal closed environment, totaling five rooms for the study. The rooms were monitored between the end of July and the end of August 2019 in Goiania (GO). Results Although assistance measures are used to significantly improve air pollution in times of extreme drought, there was a significant difference between them. The humidifier and a wet towel had 7.50% and 5.71% more humidity in the external relation (external control), respectively, more efficient. The volume of water, however, did not show significant difference (p>0.05) and, therefore, there was no variation. Conclusion The humidifier and the towel are treatments considered more efficient, and that there was a significant effect of distance on humidity. Therefore, 1m of distance is more efficient in increasing and/or maintaining air humidity, inducing improvements in the populations' health.


RESUMO Objetivo A umidade e a temperatura são fundamentais para o equilíbrio no ciclo da vida dos seres vivos e, consequentemente, para manter o bem-estar da população humana e diminuir a prevalência de doenças infecciosas. Visando mitigar o impacto das alterações climáticas, principalmente no período em que a umidade não é a ideal, é preciso adotar algumas medidas assistencialistas. O presente estudo visa elucidar qual seria a opção mais indicada para melhorar a qualidade de vida do ser humano e esclarecer qual melhor recurso (umidificador de ar, balde com água ou toalha molhada) é eficaz para melhorar a umidade do ar em épocas de seca e baixa umidade. Métodos Estudo experimental realizado com higrômetros INKBIRD que permitiram a análise da variação da umidade do ar ao longo do dia. Foram estabelecidas três formas de tratamento: umidificador, toalha molhada e balde com água. Em cada quarto, foram colocados dois higrômetros equidistantes do ocupante do quarto e seu respectivo tratamento, que variava entre 1m e 2m de distância da cabeceira da cama dentro de cada cômodo. Além disso, dois ambientes foram utilizados como controle, sendo um externo e outro fechado interno, totalizando cinco cômodos para o estudo. Os cômodos foram monitorados entre o final do mês de julho até final do mês de agosto de 2019 em Goiânia (GO). Resultados Apesar de as medidas assistencialistas serem utilizadas para melhora significativa da umidade do ar em épocas de extrema seca, há uma diferença significativa entre elas. O umidificador e a toalha molhada possuíram 7,50% e 5,71% a mais de umidade em relação à área externa (controle externo), respectivamente, sendo considerados mais eficientes. Já o balde de água não se diferenciou significativamente (p>0,05), não havendo variação. Conclusão O umidificador e a toalha foram os tratamentos considerados mais eficientes, com efeito significativo da distância sobre a umidade. Portanto, 1m de distância é mais eficiente no aumento e/ou na manutenção da umidade do ar, induzindo melhorias na saúde da população.

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

During the high-temperature and rainy season from June to October in 2017-2019,serious southern blight broke out in the Cynanchum stauntonii planting area in Tuanfeng county,Hubei province,which had a great impact on the yield and quality of medicinal materials. In this study,the pathogen of C. stauntonii was isolated,purified,and identified,and the pathogenicity was tested according to Koch's postulates. Meanwhile,the biological characteristics of the pathogen were analyzed. On this basis,the effective fungicides were screened in laboratory. Finally,the pathogen( BQ-1) was identified as Athelia rolfsii( Deuteromycotina,Basidiomycota,anamorph: Sclerotium rolfsii). The optimum growth conditions for BQ-1 were 25-30 ℃,p H 5-8,and alternating light and dark.The effective chemical fungicides were lime-sulphur-synthelic-solution( LSSS) and flusilazole,and the effective botanical fungicide was osthole. BQ-1 was highly homologous to the pathogen HS-1 of peanut southern blight,with the similarity of 18 S r DNA and TEF sequences at 99. 09%. The southern blight in C. stauntonii might be resulted from that in peanut. In the production of C. stauntonii,the following measures should be taken: avoiding rotation or neighboring with peanut,draining water from June to October to reduce humidity,and reasonably applying fungicides.

ABSTRACT

Fish and fish products are an outstanding source of essential protein and micronutrients. In cured meats, such as pâté, the technological characteristics are fundamental to the final quality of the product. The present study aimed to evaluate the effect of the addition of manioc starch, water and inulin on moisture, water holding capacity (WHC) and texture profile in pâtés using the underutilized marine fish bicuda (barracuda, Sphyraenatome) with total fat replacement by inulin. A Rotational Central Composite Design (RCCD) was used with the independent variables inulin, manioc starch, and water. Water, inulin, and manioc starch significantly influenced (p<0.05) the moisture content of pâtés, WHC, and texture, hardness, gumminess, and chewiness parameters. The technological action of inulin as a substitute for fat used in the formulations (3% to 6%) was underestimated. The percentages used were below perecentages of at least 20% of fat reported in the literature.Current legislation does not recommend WHR values and hardness parameters, only values for humidity. There is a need for revision of legislation to meet the characteristics of the identity pattern and quality of fish pâté.


El pescado y los productos pesqueros son una fuente excepcional de proteínas esenciales y micronutrientes. En embutidos (carne curada) como el paté, las características tecnológicas son fundamentales para la calidad final del producto. El presente estudio tuvo como objetivo evaluar el efecto de la adición de almidón de mandioca, agua e inulina sobre la humedad, la capacidad de retención de agua (WHC) y el perfil de la textura en patés fabricados con peces marinos subutilizados (barracuda, Sphyraena tome) con reemplazo total de grasa por inulina. Se utilizó un diseño compuesto central rotatorio (RCCD) con las variables independientes inulina, almidón de mandioca y agua. El agua, la inulina y el almidón de mandioca influyeron significativamente (p<0.05) en el contenido de humedad de los patés, WHC, y los parámetros de textura, dureza, gomosidad y masticabilidad. Se subestimó la acción tecnológica de la inulina como sustituto de la grasa en los contenidos utilizados en las formulaciones (3% a 6%). Los porcentajes utilizados estaban por debajo de lo que informa la literatura de al menos un 20% de grasa. La legislación actual no recomienda valores de WHR y parámetros de dureza, solo valores de humedad. Es necesario revisar la legislación para cumplir con las características del patrón de identidad y la calidad del paté de pescado.

ABSTRACT

Elephant grass silages have high moisture content, causing nutrient loss, mainly by effluent production. The use of moisture absorbent additives, such as patauá, Oenocarpus bataua meal, can be a strategy to reduce losses in these silages. The aim of this study was to determine the fermentation losses, microbiological composition, fermentative characteristics, and chemical composition of elephant grass silage with increasing levels of inclusion of patauá meal. The experiment was conducted in a completely randomized design, with four concentrations of patauá meal (7%, 14%, 21%, and 28%, based on fresh matter) and a control without patauá, and five replicates. The elephant grass was collected manually after 60 days of growth. After chopping, the grass was homogenized, mixed with the patauá meal according to the established treatments, and ensiled in experimental silos of 15 L. The inclusion of patauá meal in elephant grass silage had positive effects on the chemical composition and effluent loss. It significantly increased dry matter, organic matter, crude protein, nitrogen insoluble in neutral detergent and acid, ethereal extract, lignin, and non-fibrous carbohydrates of the silages. It also reduced effluent losses, neutral and acid detergent fiber contents, and cellulose. Our findings contribute towards reducing the environmental impact caused by the production of effluents during ensilage of tropical grasses and providing a potential use for the residue from the production of patauá oil, thus avoiding disposal in the environment.

ABSTRACT

Forest Red Gum eucalypt provides a versatile wood and is converted into different purposes. However, such wood is somewhat limited in structural ends, which highlights the need to exploit this gap through diffusion of mechanical properties of suchtimber. This study aimed to evaluate the effect of moisture content reduction, from 30 to 12%, in physical and mechanical properties of Eucalyptus tereticornis, using Brazilian and American documents, to reinforce the structural potential wood and assisting engineers and architects in decision-making for its best building application. We evaluated two physical and fourteen mechanical properties of Eucalyptus tereticornis at two different moisture contents, following the prescriptions of Brazilian (ABNT NBR 7190: 1997) and North American (ASTM D-143-14: 2014) standards. Thus, 1091 repeats were carried out for all properties. By a moisture reduction, the bulk density and eleven strength properties statistically showed changes such as modulus of rupture (static bending, parallel and perpendicular compressions), modulus of elasticity (perpendicular compression and static bending), shear stress, tangential cleavage, and parallel and perpendicular hardnesses. Then, the Eucalyptus tereticornis timber could be better usable if is further applied for structural construction uses.


Eucalipto de goma vermelha prove uma madeira versátil e é convertido para diferentes propósitos. Porém, essa madeira é um pouco limitada para fins estruturais, o que destaca a necessidade de explorar essa lacuna mediante à difusão das propriedades mecânicas de tal madeira. Os resultados obtidos deverão auxiliar os engenheiros e arquitetos na tomada de decisão para a sua melhor aplicação construtiva. Esse artigo estudou a avaliação de duas propriedades físicas e catorze propriedades mecânicas do Eucalyptus tereticornis em dois teores de umidade, seguindo as prescrições dos documentos normativos brasileiro (ABNT NBR 7190: 1997) e norte-americano (ASTM D-143-14: 2014). Assim, 1091 repetições foram conduzidas para todas essas propriedades. Pela redução de umidade de 30% para 12%, a densidade aparente e onze propriedades de resistência demonstraram estatisticamente mudanças, tais como módulos de ruptura (flexão estática ecompressões paralela e perpendicular), módulos de elasticidade (compressão perpendicular e flexão estática), cisalhamento, fendilhamento e as durezas perpendicular e paralela. Então, a madeira de Eucalyptus tereticornispoderia ser melhor utilizável se for também aplicada para usos construtivos estruturais.

ABSTRACT

Abstract Beauveria bassiana is a promising fungus for the biological control of insect pests. The growing costs of conidia production have raised the need to ascertain the efficiency of some low cost substrates. The aim of this study was to analyze the potential use of different raw substrates without nutritional supplement for B. bassiana conidiogenesis. Growth and sporulation were evaluated using 30 g of substrate and 0.3 μL of a conidia suspension (1 x 106 conidia/mL). After 10 days of incubation (70 ± 10% humidity and temperature (T) = 29 ± 1 °C), rice (2.00 x 106 conidia/g substrate), algaroba (2.36 x 106 conidia/g), malt A (1.22 x 106 conidia/g) and malt B (1.75 x 106 conidia/g) showed the highest levels of conidia production. The resulting conidia showed insecticidal activity higher than 80% on coconut termites. These new raw substrates may represent viable alternatives for the production of entomopathogenic fungi for use in the biological control of various insect pests.


Resumo Beauveria bassiana é um fungo promissor no controle biológico de insetos-praga. As crescentes despesas na produção de conídios levantam a necessidade de averiguar a eficiência de alguns substratos de baixo custo. O objetivo deste trabalho foi analisar o potencial de utilização de diferentes substratos brutos para a conidiogênese de B. bassiana. O crescimento e esporulação foram realizados utilizando 30 g do substrato e 0,3 µL da suspensão de conídios (1 x 106 conídios/mL). Após 10 dias de incubação (umidade 70 ± 10% e temperatura T = 29 ± 1° C), o arroz (2,00 x 106 conídios/g de substrato), algaroba (2,36 x 106 conídios/g), malte A (1,22 x 106 conídios/g) e B (1,75 x 106 conídios/g), apresentaram maior produção de conídios. Os conídios produzidos mostraram atividade inseticida sobre o cupim do coqueiro acima de 80% de mortalidade. Estes novos substratos brutos podem representar uma alternativa viável para produção de fungos entomopatogênicos para uso no controle biológico de vários insetos praga.

ABSTRACT

Objective: To analyze the correlation between weather, population size and cases of COVID-19 in the capitals of Brazil. Methods: All confirmed cases of COVID-19 infection, from the first confirmed case from February 26 until May 01, 2020 were included. For weather variables, average temperature (°C), dew point (°C), average humidity (%) and wind speed (m s-1) were extracted from the Instituto de Meteorologia database. The population size of each capital was used as a control variable, with data obtained from Instituto Brasileiro de Geografia e Estatística. Spearman rank correlation tests were utilized to examine the correlation between variables. Results: The analysis showed a significant and strong positive correlation between the total cases of COVID-19 and the population size (p<0,01). There was a significant positive correlation with the average humidity of the air and cumulative cases (p<0,05). There was no significant correlation with other climate variables. Conclusion: Our results confront some expectations commented around the world about a possible seasonality of COVID-19 during periods of low humidity and can assist government and health authorities in decision making to control the pandemic. Studies in other regions are important to strengthen the findings.

ABSTRACT

Abstract INTRODUCTION: Snakebites represent a serious global public health problem, especially in tropical countries. In Brazil, the incidence of snakebites ranges from 19 to 22 thousand cases per 100000 persons annually. The state of Rondônia, in particular, has had an increasing incidence of snakebites. METHODS: A retrospective cross-sectional study on snakebites was conducted from January 2007 to December 2018. Brazil's Information System for Notifiable Diseases was queried for all snakebites reported in Porto Velho, Ariquemes, Cacoal, and Vilhena. Data on land surface temperatures during the day and night, precipitation, and humidity were obtained using the Google Earth Engine. A Bayesian time series model was constructed to describe the pattern of snakebites and their relationship with climate data. RESULTS: In total, 6326 snakebites were reported in Rondônia. Accidents were commonly caused by Bothrops sp. (n=2171, 81.80%). Snakebites most frequently occurred in rural areas (n=2271, 85.5%). Men, with a median age of 34 years (n=2101, 79.1%), were the most frequent bitten. Moderate clinical manifestation was the most common outcome of an accident (n=1101, 41.50%). There were clear seasonal patterns with respect to rainfall, humidity, and temperature. Rainfall and land surface temperature during the day or night did not increase the risk of snakebites in any city; however, changes in humidity increased the risk of snakebites in all cities. CONCLUSION: This study identified the population exposed to snakes and the influence of anthropic and climatic factors on the incidence of snakebites. According to climate data, changes in humidity increased the risk of snakebites.

ABSTRACT

Pectin industry generates a citrus pulp residue compounded by peduncle, endocarp, juice vesicles, columella, seeds and tiny fractions of epicarp and mesocarp of citrus fruits, denominated Wet Citrus Pulp (WCP), which has not yet been tested as food for lamb's nutrition. Thus, this study aimed to determine the effect of partial replacement of ground corn by WCP in high-concentrate diets on the performance and hepatic enzyme concentration of feedlot lambs. Forty-two male lambs (15 Santa Inês and 27 ½ Dorper × Santa Inês), with 24.7 ± 1.5 kg of BW and 60 ± 5 d of age was assigned to a randomized complete block design. Within blocks (n = 14), lambs were randomly assigned to 1 of 3 treatments: 0WCP (control) ­ diet containing 75.5% ground corn without WCP; 20WCP ­ diet containing 20% WCP in replacement of ground corn, and 40WCP ­ diet containing 40% WCP in replacement of ground corn. The experiment lasted 70 days, which was split in 3 experimental periods (14 days of diets' adaptation and 2 sub-periods of 28 days each). Statistical analyses were performed using the MIXED procedure of the SAS. Orthogonal polynomials for diet response were determined by linear and quadratic effects. There was a quadratic effect for DM, CP, ash, ether extract and NFC intake The highest DM and CP intake was observed for lambs fed 20WCP, however, the control diet increased the ash, ether extract and NFC intake. The increased levels of WCP decreased the ADG and feed efficiency (FE) during the adaptation period, however, did not affect the ADG and FE on periods 1 and 2. Consequently, the increased levels of WCP inclusion decreased linearly the BW. There was no effect of WCP inclusion in diets on Gamma-Glutamyl Transferase (GGT) concentration. However, there was a linear increase for Aspartate Aminotransferase (AST) concentration during the adaptation period, but without difference in other periods. In conclusion, adding up to 40% of WCP in finishing diets for feedlot lambs decrease performance during adaptation period, compromising the final body weight, but without damages effects on liver enzymes.(AU)


A indústria de produção de pectina gera um resíduo composto por pedúnculo, endocarpo, vesículas de suco, columela, sementes e minúsculas frações de epicarpo e mesocarpo de frutas cítricas, denominada Polpa Cítrica Úmida (WCP), que ainda não foi testada como alimento na nutrição de ovinos. Sendo assim, este estudo teve como objetivo avaliar o efeito da substituição parcial do milho pela WCP em dietas contendo elevado teor de concentrado sobre o desempenho e a concentração de enzimas hepáticas de cordeiros confinados. Quarenta e dois cordeiros machos (15 Santa Inês e 27 ½ Dorper x Santa Inês), com 24,7 ± 1,5 kg de peso corporal e 60 ± 5 dias de idade foram distribuídos em delineamento de blocos completos casualizados. Dentro de cada bloco (n = 14), os cordeiros foram distribuídos aleatoriamente entre os tratamentos: 0WCP ­ dieta contendo 75,5% de milho moído, sem a inclusão de WCP; 20WCP ­ dieta contendo 20% de WCP em substituição ao milho moído; e 40WCP ­ dieta contendo 40% de WCP em substituição ao milho moído. O experimento teve duração de 70 dias, sendo dividido em 3 períodos experimentais (14 dias de adaptação as dietas e 2 períodos de 28 dias cada). As análises estatísticas foram realizadas utilizando o procedimento MIXED do SAS. Os polinômios ortogonais lineares e quadráticos foram utilizados para avaliar o efeito das dietas. Houve efeito quadrático para o consumo de matéria seca, PB, cinzas, extrato etéreo e CNF. A maior ingestão de MS e PB foi observada para os cordeiros alimentados com 20WCP, entretanto, a dieta controle aumentou o consumo de cinzas, extrato etéreo e CNF. O aumento na inclusão de WCP diminuiu o ganho médio diário e a eficiência alimentar durante o período de adaptação, entretanto, não afetou essas variáveis durante os períodos 1 e 2. Consequentemente, a inclusão de WCP reduziu o peso corporal ao final do período experimental. Não houve efeito das dietas na concentração de gama-glutamil transferase (GGT). Entretanto, houve aumento linear na concentração de aspartato aminotransferase (AST) durante o período de adaptação. Em conclusão, a inclusão de até 40% de WCP nas dietas de terminação para cordeiros confinados diminuiu o desempenho durante o período de adaptação, comprometendo o peso corporal ao final do período experimental, entretanto, não comprometeu a afetou as enzimas hepáticas.(AU)

ABSTRACT

@#Introduction: Dengue continues to be a major health concern in the Philippines. This study aimed to establish trends and correlations between the incidence of dengue and rainfall, humidity and temperature, respectively, in the different regions. Methods: Using 2018 records obtained from DOH and PAGASA, correlations were made between monthly measurements of climatic factors and the incidence of dengue using Pearson’s r, while maps and interpolations were generated using quantum geographical information system software. Results: There was a significant positive but weak correlation between the incidence of dengue and rainfall (r = 0.379, 95% CI 0.255, 0.491; p < 0.001) and humidity (r = 0.215, 95% CI 0.080, 0.342; p = 0.002). There was a significant negative but weak correlation between the incidence of dengue and temperature (r = -0.145, 95% CI -0.277, -0.008; p = 0.039). A strong positive correlation was noted between the incidence of dengue, and rainfall and humidity, respectively, in several regions. Multiple regression indicates that rainfall, humidity and temperature are poor predictors of the incidence of dengue (R2 = 0.1436, 0.0461 and 0.0209, respectively). Conclusion: This study showed overall a significant but weak correlation between an increased incidence of dengue and heavy rainfalls and high relative humidity, and a weak negative correlation for temperature. A high positive correlation of an increased incidence of dengue and heavy rainfalls and high relative humidity was observed in several regions.

ABSTRACT

Abstract Introduction: The use of saline irrigation for nasal washes is a well established procedure in the treatment of sinonasal inflammation and infection. In addition to saline solutions, Ringer's lactate is also an efficient option for nasal washes and humidification. Objective: To assess the comfort, humidification and tolerance regarding stinging sensation, provided by sodium chloride nasal gel at the concentrations of 4.5 mg/g and 6.0 mg/g through questionnaires answered by the patients. Methods: A total of 60 patients, 56 females, aged between 22 and 66 years old (mean age of 47) and 4 males, aged between 36 and 66 years (mean age of 49), were included in the study for a period of 17 days (±2 days) treatment. The patients were monitored by a general practitioner throughout the study period. They were instructed to apply each product in both nostrils twice a day during a 7-day period (±2 days). The patients were evaluated prior to the use of the first product at visit 0 (V0), after 7 days of treatment (±2 days) at visit 1 (V1), after 3 days of product discontinuation at visit 2 (V2) and after 7 days (±2 days) of treatment with the second product, in visit 3 (V3). Results: A significant difference (5% significance) was observed regarding comfort and stinging sensation between the two different concentrations; comfort was higher and stinging was lower with the 6.0 mg/g concentration gel. No difference in humidification was observed between the two treatments. Conclusion: Ringer's lactate at the concentration of 6.0 mg/g was superior to that at 4.5 mg/g for parameters comfort and stinging sensation. No statistical difference was observed between the two products regarding nasal humidification.

ABSTRACT

Resumo O objetivo deste artigo é avaliar o impacto das emissões da queima da cana-de-açúcar sobre o número de internações hospitalares por doenças respiratórias em uma região canavieira. Registros de internações hospitalares por doenças respiratórias foram adquiridas a partir da base de dados referentes ao sistema de informações hospitalares do sistema único de saúde (SIH-SUS), no período de 28 de março de 2011 a 28 de dezembro de 2012. Níveis de MP10, NO2, O3, temperatura e umidade relativa foram registradas. Modelos de regressão logística foram construídos para analisar a associação entre o número total de internações, poluentes atmosféricos e variáveis meteorológicas. Foram registradas 1.179 internações, dentre elas a pneumonia mostrou aumento significativo no período de queima (p = 0,005). Neste mesmo período observou-se que o cluster MP10 e NO2 influenciou 67,9% (IC95%: 11,111-2,537), seguido do cluster MP10, NO2, O3 e temperatura que influenciou 91,1% (IC95%: 1,116; 3,271) no número total de internações. Durante o período de queima houve maior número de internações por doenças respiratórias, principalmente de pneumonia, quando foi observada a influência dos poluentes e temperatura no processo de adoecimento da população.


Abstract The scope of this article is to evaluate the impact of emissions from sugarcane burning on hospital admission numbers for respiratory diseases in a sugarcane region. Hospital admission records for respiratory diseases were acquired from the database of the Hospital Information System of the Unified Health System (SIH-SUS) in the period from March 28, 2011 to December 28, 2012. Levels of PM10, NO2, O3, Temperature and Relative Humidity were recorded. Logistic regression models were created to analyze the association between the total number of hospitalizations, atmospheric pollutants and meteorological variables. A total of 1,179 hospitalization admissions were recorded, with a significant increase in cases of pneumonia in the burning period (p = 0.005). Likewise, it was observed that the cluster of PM10 and NO2 was influenced 67.9% (95% CI: 11.111-2.537) followed by cluster PM10, NO2, O3 and Temperature that influenced 91.1% (95% CI: 1.116; 3.271) in the total number of hospitalization admissions. During the sugarcane burning period there were more hospitalization admissions due to respiratory tract diseases, mainly pneumonia, where the influence of air pollutants and temperature in the process of illness in the population was detected.

ABSTRACT

The objective of the present study was to establish the bioclimatic zoning by the temperature and humidity index (THI), considering a historical period and a future scenario, in order to represent the thermal environment for broiler breeding in the State of Minas Gerais. A historical series (1976 - 2014) of THI minimum, average and maximum calculated based on data from 48 conventional meteorological stations was used, belonging to the National Institute of Meteorology of the State of Minas Gerais. The analysis of the temporal series was based on the Mann-Kendall test and linear regression. A geostatistical analysis was also carried out to determine the comfort zoning of broilers as a function of the THI intervals. In this way, the THI spatial mapping methodologies and trend analysis for the prediction of a possible future climate scenario can help in the development of risk maps for monitoring thermal comfort of broilers, being indispensable in the planning of actions for the mitigation of the climatic change impacts on the productive chain of the State of Minas Gerais.(AU)


O objetivo do presente trabalho foi estabelecer o zoneamento bioclimático por meio do índice de temperatura e umidade (ITU), considerando-se um período histórico e um cenário futuro, de forma a representar o ambiente térmico para criação de frangos de corte no estado de Minas Gerais. Foi utilizada uma série histórica (1976 - 2014) de ITU mínimo, médio e máximo, que foram calculados com base em dados oriundos de 48 estações meteorológicas convencionais, pertencentes ao Instituto Nacional de Meteorologia do Estado de Minas Gerais. A análise da série temporal se baseou no teste de Mann-Kendall e na regressão linear. Procedeu-se, também, à análise geoestatística para determinação do zoneamento do conforto de frangos de corte segundo os intervalos de ITU. Dessa forma, as metodologias de mapeamento espacial do ITU e a análise de tendência para predição de um possível cenário climático futuro podem auxiliar no desenvolvimento de mapas de risco para o monitoramento do conforto térmico de frangos de corte, sendo indispensáveis no planejamento de ações para mitigação dos impactos das mudanças climáticas sobre a cadeia produtiva do estado de Minas Gerais.(AU)

ABSTRACT

Resumo A morbimortalidade por doenças diarreicas infecciosas ainda representa um grave problema de saúde no Brasil e está altamente relacionada a fatores como condições climáticas, ambientais e de vida da população. O objetivo deste estudo foi analisar a associação das taxas de internações por doenças diarreicas infecciosas na população do município de Rio Branco/AC com a precipitação, o nível do rio, a umidade e a temperatura, entre os anos de 2000 e 2013. Os dados foram extraídos do Sistema de Informações Hospitalares do SUS, do Instituto Nacional de Meteorologia e da Agência Nacional das Águas. Foram ajustados modelos múltiplos de regressão de Poisson e binomial negativa. Os resultados mostram que existe uma associação positiva entre as internações por doenças diarreicas infecciosas e o nível do Rio Acre (RT:1,07; IC95%:1,04 a 1,1); houve um decréscimo de 14% nestas taxas de internações entre os anos de 2000 e 2013 (RT:0,86; IC95%:0,85 a 0,87); o grupo mais vulnerável pertence à faixa etária de menores de 1 ano de vida. Este estudo mostrou a vulnerabilidade de uma cidade na Amazônia quanto à variabilidade climática e a respectiva influência epidemiológica na incidência de internações por doenças diarreicas infecciosas.


Abstract Morbimortality due to infectious diarrheal diseases still is a serious health issue in Brazil and is highly related to factors such as weather, environment, and people's life conditions. This study aimed to analyze the relationship between hospitalization rates due to infectious diarrheal diseases among the population of the municipality of Rio Branco (AC), Brazil and precipitation, river level, humidity and temperature between 2000 and 2013. Data were retrieved from the Hospital Information System of the SUS (Unified Health System), the National Institute of Meteorology and the National Water Agency. Multiple Poisson and negative binomial regression models were adjusted. Results showed that there is a positive association between hospitalization due to infectious diarrheal diseases and the level of the Acre river (RR: 1.07; CI 95%: 1.04 to 1.1); these hospitalization rates fell 14% between 2000 and 2013 (RR: 0.86; CI 95%: 0.85 to 0.87). The most vulnerable group was the age group of less than 1 year of age. This study showed the vulnerability of an Amazonian city to climate variability and its respective epidemiological influence on the incidence of hospitalizations due to infectious diarrheal diseases.
