Spatio-temporal GAMLSS modeling of the incidence of schistosomiasis in the central region of the State of Minas Gerais, Brazil. / Modelagem GAMLSS espaçotemporal da incidência de esquistossomose na região central do Estado de Minas Gerais, Brasil.

In Brazil, millions of people live in areas with risk of schistosomiasis, a neglected chronic disease with high morbidity. The Schistosoma mansoni helminth is present in all macroregions of Brazil, including the State of Minas Gerais, one of the most endemic states. For this reason, the identification of potential foci is essential to support educational and prophylactic public policies to control this disease. This study aims to model schistosomiasis data based on spatial and temporal aspects and assess the importance of some exogenous socioeconomic variables and the presence of the main Biomphalaria species. Considering that, when working with incident cases, a discrete count variable requires an appropriate modeling, the GAMLSS modeling was chosen since it jointly considers a more appropriate distribution for the response variable due to zero inflation and spatial heteroscedasticity. Several municipalities presented high incidence values from 2010 to 2012, and a downward trend was observed until 2020. We also noticed that the distribution of incidence behaves differently in space and time. Municipalities with dams presented risk 2.25 times higher than municipalities without dams. The presence of B. glabrata was associated with the risk of schistosomiasis. On the other hand, the presence of B. straminea represented a lower risk of the disease. Thus, the control and monitoring of B. glabrata snails is essential to control and eliminate schistosomiasis; and the GAMLSS model was effective in the treatment and modeling of spatio-temporal data.

No Brasil, milhões de pessoas vivem em áreas de risco para a esquistossomose, uma doença negligenciada, de caráter crônico e com elevada morbidade. O helminto Schistosoma mansoni está presente em todas as macrorregiões, incluindo o Estado de Minas Gerais, um dos mais endêmicos. Por essa razão, a identificação de potenciais focos é fundamental para subsidiar políticas públicas de cunho educativo e profilático no controle desse desfecho. Nesse contexto, o objetivo do trabalho consiste em modelar dados de esquistossomose em relação aos aspectos espaciais e temporais, além de avaliar a importância de algumas variáveis exógenas socioeconômicas e a presença das principais espécies de Biomphalaria. Como trabalhar com casos incidentes, uma variável discreta de contagem, exige uma modelagem apropriada, foi escolhida a modelagem GAMLSS por considerar conjuntamente uma distribuição mais adequada à variável resposta devido à inflação de zeros e à heterocedasticidade espacial. Verificaram-se valores elevados de incidência em diversos municípios de 2010 a 2012 e uma tendência de queda até 2020. Também foi identificado que a distribuição da incidência se comporta de maneira diferente no espaço e no tempo. Municípios com barragem apresentaram risco 2,25 vezes maior do que os que não a continham. A presença de B. glabrata foi relacionada ao risco de ocorrência da doença. Por outro lado, a presença de B. straminea refletiu em menor risco de ocorrência da esquistossomose. Conclui-se que o controle e o acompanhamento dos caramujos da B. glabrata podem ser fundamentais para a contenção e a eliminação da esquistossomose e o modelo GAMLSS foi eficaz para tratamento e modelagem de dados espaçotemporais.

Por ello, la identificación de potenciales brotes es fundamental para promover políticas públicas de carácter educativo y profiláctico en el control de este desenlace. En este contexto, el objetivo de este trabajo es modelar datos sobre esquistosomiasis con respecto a aspectos espaciotemporales, además de evaluar la importancia de algunas variables socioeconómicas exógenas y la presencia de las principales especies de Biomphalaria. Dado que en el trabajo con casos incidentes una variable de conteo discreta requiere un adecuado modelado, se eligió el modelo GAMLSS, ya que en conjunto considera una distribución más adecuada para la variable de respuesta debido a la inflación de ceros y la heterocedasticidad espacial. Se encontraron valores de alta incidencia en varios municipios en el periodo evaluado de 2010 a 2012 y una tendencia a descenso hasta 2020. También se verificó que existe una distribución de incidencia de manera diferente en el espacio y el tiempo. Los municipios con represas presentaban 2,25 veces más riesgo que los que no las tenían. La presencia de B. glabrata estuvo relacionada con el riesgo de la enfermedad. Por otro lado, la presencia de B. straminea ocasionaba un menor riesgo de padecer la enfermedad. Se concluye que el control y seguimiento de caracoles B. glabrata puede ser fundamental para el control y eliminación de la esquistosomiasis y que el modelo GAMLSS resultó ser efectivo para el tratamiento y modelado de datos espaciotemporales.

Irisin effects on bone: systematic review with meta-analysis of preclinical studies and prospects for oral health.

Bone quality is an important issue in dentistry. Low bone density may be associated with more severe periodontitis, and may influence implant therapy success. Recent evidence suggests that physical activity can improve alveolar bone quality. Irisin is an exercise-mediated peptide that might be involved in this process. We assessed the effect of exercise and that of intra-peritoneal irisin administration on bone quality in healthy and osteoporosis-induced rodents. This study was registered at PROSPERO (CRD42020184140), and followed PRISMA guidelines. A search by two independent examiners was conducted in five databases and gray literature up to July 2021, without restrictions regarding language or date of publication. Initially, they analyzed retrieved titles and abstracts (n=3,844) based on eligibility criteria. Of this total, 19 studies remained for full-text reading, and 16 proceeded to the data extraction and quality assessment phases. Meta-analyses were conducted (n= 6 studies) to establish the effects of irisin administration on cancellous bone mineral density (BMD). Exercise or irisin administration enhanced bone quality, but the meta-analysis showed that BMD increased only slightly in osteoporotic rodents (BMD: mean difference 0.03 mg/cm3 - 95% CI 0.01-0.05). This indicates that they had no significant benefits on the bones of healthy animals. Implications of key findings evidence the potential of irisin as an agent able to mitigate bone loss caused by osteoporosis, an outcome that could favor dental rehabilitation. More studies investigating the effect of irisin on alveolar bone are needed to elucidate its therapeutic viability and implications.

Impacts of quaker beans over sensory characteristics and volatile composition of specialty natural coffees.

The objective of this study was to evaluate the volatile composition and the sensory effect of the presence of Quaker beans in natural specialty coffee beverage and, consequently, to confront the requirement of the Specialty Coffee Association regarding the total absence of Quaker beans in a natural specialty coffee batch. Sensory analysis and volatile composition were performed for three different colorations of Quaker beans, added separately to natural specialty coffee samples at seven different concentrations. Beans with color equal to or above Agtron 82.8 negatively affected the sensory characteristics of natural specialty coffee only from the presence of 7 Quaker beans in one cup (65 beans). Through the analysis of volatile composition, volatile compounds formed during roasting were identified in Quaker beans from precursors present in raw immature beans. Therefore, the color and sensory characteristics of Quaker are a consequence of the chemical composition of an immature bean.

Embryo yield and quality are associated with progestogen treatment during superovulation protocol in lactating Lacaune ewes.

This study assessed the effect of progestogen treatment length on ovarian parameters and embryo yield in superovulated Lacaune ewes collected by nonsurgical embryo recovery. Twenty-three lactating ewes were superovulated 30 d apart using a cross-over design. All ewes received 60 mg of MAP intravaginal sponges for 6 (G-6 group) or 9 (G-9 group) d. A total dose of 133 mg pFSH was given in six decreasing doses (twice a day) starting at 60 h before device removal. Ultrasound examination of the ovaries was performed at the first pFSH injection and one day before embryo recovery, which was performed 6-7 d after the onset of estrus. Embryo recovery was conducted only in ewes that expressed estrus and were mated. There was no difference (P > 0.05) in the total number of follicles between G-6 (15.7 ± 1.0) and G-9 (15.6 ± 0.8) at the time of the first pFSH treatment. The percentage of responding donors with ≥3 corpora lutea (CL; 78.2% [18/23] vs 69.5% [16/23]), mean (±SEM) CL number (7.0 ± 1.2 vs 8.1 ± 1.6), transcervical passage rate (94.4% [17/18] vs 83.3% [15/18], and ova/embryo recovery rate (54.5% [60/110] vs 68.0% [83/122]) were not different (P > 0.05) between the G-6 and G-9 groups. However, the mean number of viable embryos was lower (P < 0.05) in the G-6 group (1.8 ± 0.7) than in the G-9 group. (3.5 ± 1.1). In conclusion, treatment with an intravaginal MAP sponge for 9 d during a superovulation protocol is beneficial for viable embryo yield in Lacaune ewes out of the breeding season.

Ovarian follicular development, hormonal and metabolic profile in prepubertal ewe lambs with moderate dietary restriction and lipid supplementation.

To evaluate the effects of moderate dietary restriction and lipid supplementation on ovarian follicular development, hormonal and metabolic profile, thirty-five prepuberal ewe lambs were blocked by body weight and randomly assigned to treatments: ALUS (control) - unsupplemented-diet ad libitum (3.5% ether extract, n = 9); R-US - intake restricted to 85% of the ALUS diet (n = 9); AL-LS - lipid-supplemented-diet ad libitum (9.8% ether extract, n = 8); R-LS - intake restricted to 85% of the ALLS diet (n = 9), from 95 ± 8 days of age until estrus or 7 months of age. Lipid supplementation did not reduce dry matter intake. Daily weight gain was greater in lambs fed ad libitum. Plasma glucose was greater in the RLS treatment group, while serum insulin was less with lipid supplementation. There was a treatment by age interaction on total cholesterol, HDL cholesterol and triglyceride serum concentrations. Estrus was detected in 43% of the animals and the overall ovulation rate was 60%. The number of follicles, diameter of the largest follicle, body weight, age and serum progesterone at puberty did not differ among treatment groups. The mean diameter of the largest follicle was greater in lambs having than in those not having ovulations and increased with age in both groups. There was an interaction between the effects of occurrence of ovulation and age on the number of follicles between 3 and 5 mm and > 5 mm. Lipid supplementation and dietary restriction altered the metabolic profile in ewe lambs with no concomitant changes in values for reproductive variables.

Economic evaluation and efficacy of strategic-selective treatment of gastrointestinal parasites in dairy calves.

In the Experimental Farm of the Universidade Federal de Lavras (EF-UFLA), state of Minas Gerais, Brazil, on their day of birth, female Holstein calves were randomly selected and placed into two groups containing fifteen animals each: Strategic-Selective Treatment (S-ST) or Conventional Treatment (CT). In the S-ST, calves were treated after coproparasitological examinations according to criteria established previously by the researchers. Calves in the CT were treated according to the opinion of the veterinarian of EF-UFLA. For statistical analysis, the frequency (%) of fecal samples with count of eggs per gram of feces (EPG) ≥300, count of oocysts per gram of feces (OoPG) ≥500 and fecal samples with count of cysts of Giardia spp. ≥1 were conducted. The overall average frequency of fecal samples with EPG ≥300, OoPG ≥500 and Giardia spp. cysts ≥1, respectively, was similar (p >0.05) between S-ST (20.3%; 17.3%; and 31.5%) and CT (26.4%; 23.9%; and 37.3%). The effective operational cost, per animal, in 12 months, was of R$ 784.58 (US$ 241.41) and R$ 83.90 (US$ 25.81) in S-ST and CT, respectively. The S-ST requires adjustments to be used as a technically efficient and economically viable alternative for the control of gastrointestinal parasitosis in female Holstein calves.

Resumo Na Fazenda Experimental da Universidade Federal de Lavras (FE-UFLA), Minas Gerais, Brasil, no dia do nascimento, bezerras da raça holandesa foram sorteadas de forma aleatória para compor um dos dois grupos, formados por 15 animais cada: Tratamento Estratégico-Seletivo (TE-S) ou Tratamento Convencional (TC). No TE-S, as bezerras foram tratadas após exames coproparasitológicos de acordo com critérios previamente estabelecidos pelos pesquisadores. No TC, as bezerras foram tratadas conforme orientação do veterinário da FE-UFLA. Em ambos grupos, as bezerras foram monitoradas a cada 14 dias, do nascimento até os 12 meses de idade, por meio de exames coproparasitológicos. Para análise estatística, considerou-se a frequência (%) de amostras fecais com contagem de ovos por grama de fezes (OPG) ≥300, contagem de oocistos por grama de fezes (OoPG) ≥500, e amostras fecais com contagem de cistos de Giardia spp. ≥1. A frequência média global de amostras fecais com contagem de OPG ≥300, OoPG ≥500 e cistos de Giardia spp. ≥1, respectivamente, foi similar (p >0,05) entre TE-S (20,3%; 17,3%; e 31,5%) e TC (26,4%; 23,9%; e 37,3%). O custo operacional efetivo, por animal, em 12 meses, foi R$ 784,58 (US$ 241.40) e R$ 83,90 (US$ 25.81) para TE-S e TC, respectivamente. O TE-S necessita de ajustes para que possa ser indicado como uma alternativa, tecnicamente eficiente e economicamente viável, no controle das parasitoses gastrointestinais em bezerras leiteiras.

Equações de predição de valores energéticos de alimentos obtidas utilizando meta-análise e componentes principais / Prediction equations of energetic values of feedstuffs obtained using meta-analysis and principal components

Neste estudo, foi proposta a utilização da análise de componentes principais, na formação de grupos homogêneos de artigos científicos, a serem considerados em uma meta-análise. Nessa meta-análise, foram utilizados resultados referentes à composição química e energia metabolizável aparente corrigida pelo balanço de nitrogênio (EMAn) de alimentos para aves, na obtenção de equações de predição da EMAn. Foram considerados 293 experimentos com resultados já publicados. Dados provenientes de ensaios metabólicos foram utilizados na validação das equações de predição obtidas, sendo que estas apresentaram resultados semelhantes às disponíveis na literatura. No procedimento de meta-análise, a formação de grupos homogêneos de resultados experimentais, que é uma das maiores dificuldades, foi facilitada com a utilização de componentes principais, uma vez que não houve a necessidade de determinar variáveis ou fatores a serem considerados nessa classificação. Assim, tem-se uma forma rápida e eficiente de definir tais grupos.

The purpose of this study was to develop a meta-analysis study by using the principal components analysis to obtain homogeneous groups of experimental results. In the process of the meta-analysis, it was considered data from 293 experiments carried out in Brazil. Prediction equations were obtained to estimate the nitrogen-corrected apparent metabolizable energy (AMEn) of poultry feedstuffs. Data from metabolic trials were used to validate the prediction equations obtained, which were similar than other available equations in the literature. One of the problems in meta-analysis is the determination of the homogeneous groups of experiments and, this problem was eliminated by using principal components, since there was no need to establish variables or factors to be considered in this classification.

Predição do índice de temperatura do globo negro e umidade e do impacto das variações climáticas em galpões avícolas climatizados / Prediction of black globe humidity index and of the impact of climate changes on acclimatized broiler houses

Objetivou-se, com o presente trabalho, adaptar e validar um modelo para predição do índice de temperatura de globo negro e umidade (ITGU) no interior de galpões climatizados e analisar o efeito das variações climáticas sobre o ambiente térmico de produção por meio de cenários futuros. Os dados experimentais utilizados para o ajuste e validação do modelo matemático foram coletados em dois galpões avícolas climatizados, equipados com sistema de ventilação em modo túnel negativo e sistemas de resfriamento evaporativo do tipo material poroso umedecido e nebulização. Predições dos valores de ITGU foram estatisticamente iguais às observadas (teste t, P>0,05), com erro de 1,55±1,08 por cento. Considerando o sistema analisado, observou-se que as mudanças climáticas previstas pelos cenários futuros tornarão os ambientes menos propícios à produção de frangos de corte, especialmente nas estações de primavera e verão, nas quais os valores de ITGU foram acima do limite de conforto.

The goal of this work was to adapt and to validate a model to predict black globe humidity index (BGHI) inside of acclimatized broiler houses, and analyzing the effect of climate changes on the thermal environment of production through the future scenarios. The experimental data used to adjust and validate of mathematical model were measured in two acclimatized broiler houses equipped with negative tunnel ventilation system coupled to pad and mist cooling systems. Prediction of BGHI values were statically equal to the observed (t test, P>0.05), with error of 1.55±1.08 percent. Considering the system analyzed, the climate change foreseen by the future scenarios will turn the environment unsuitable for broiler chicken production, especially during spring and summer that presented BGHI values above to the comfort limit.

Avaliação da qualidade de vida em pacientes idosos um ano após o tratamento cirúrgico de fraturas transtrocanterianas do fêmur / Functional outcomes and quality of life one year after surgical management of trochanteric fractures

OBJETIVO: Avaliar o impacto que as fraturas transtrocanterianas produzem sobre a qualidade de vida de pacientes idosos, tratados cirurgicamente, durante o período de um ano de acompanhamento. MATERIAL E MÉTODO: Foram selecionados 73 idosos com fratura transtrocanterina, com idade igual ou superior a 65 anos de ambos os sexos. Foi aplicado questionário padronizado, para se obter informações quanto aos hábitos de vida, atividade física, funcionalidade, deambulação e estado cognitivo. Foram excluídos os óbitos ocorridos durante o estudo, pacientes que não deambulavam, com doenças neurológicas ou fraturas patológicas. RESULTADOS: A média de idade foi 80,17 ± 7,2, sendo 75 por cento do sexo feminino. Ao comparar as somatórias das atividades de vida diária (p=0,04) e instrumentais da vida diária (p=0,004), obtidas na pré e pós-fratura, os pacientes tornaram-se mais dependentes pós-fratura. Atividades de vida diária que apresentaram piora pós-fratura foram: tomar banho (p=0,04), ir ao banheiro (p=0,02) e vestir-se (p=0,04). Todas as atividades instrumentais da vida diária apresentaram diferença significativa, apresentando maior dependência funcional pós-fratura, assim como aumento da necessidade de auxílio a deambulação (p=0,00002), idade avançada (p=0,01) e não realizar atividades domésticas (p=0,01). A baixa pontuação no teste Minimental estava associada com uma maior dependência para realizar as atividades da vida diária na pré-fratura (p=0,00002) e pós-fratura (p=0,01). CONCLUSÃO: Após um ano, as atividades de vida diária que dependiam dos membros inferiores pioraram significativamente, todas as atividades instrumentais de vida diária apresentaram piora significativa em mais de 50 por cento dos pacientes e mais da metade dos pacientes que andavam sem apoio perderam esta capacidade.

OBJECTIVE: Evaluate the impact that trochanteric hip fractures produce on life quality of elderly patients, treated surgically, during one year of monitoring. METHODS: Were selected 73 elderly with transtrochanteric femur fracture, aged equal or over than 65 years and of both sexes. All participants underwent a standardized questionnaire which obtained information on lifestyle habits, functionality, physical activity, ambulation and cognitive state. Were excluded patients who died, not walking, with neurological diseases and pathological fractures. RESULTS: The average age was 80.17 ± 7.2 years and 75 percent was female. When comparing the summation of activities of daily living (p = 0.04) and instrumental daily living (p = 0.004) obtained before and after fracture, the patients become more dependent after fracture. Activities of daily living that worsened after fracture were bathing (p = 0.04), toileting (p = 0.02) and dressing (p = 0.04). All instrumental activities of daily living showed a significant difference, with functional dependence after fracture, increased need for walking aid (p = 0.00002), aged (p = 0.01) and not doing housework (p = 0.01). The low score on the test Minimental was associated with a greater dependence to perform activities of daily living before (p = 0.00002) and after (p = 0.01) fracture. CONCLUSION: After a year, activities of daily living that depended on the lower limbs worsened significantly, all instrumental activities of daily living were significantly worse in more than 50 percent of patients and more than half of patients who walked without support lost this ability.

Avaliação do bem-estar de frangos de corte em dois galpões comerciais climatizados / Evaluation of poultry well-being in two commercial climatized poultry houses

Objetivou-se, com esta pesquisa, avaliar as condições do ambiente interno em dois galpões comerciais de frangos de corte equipados com dois sistemas de resfriamento diferentes: placas porosas umedecidas de celulose associadas à nebulização (SRPN) e placas umedecidas de sombrite associadas à nebulização (SRSN). Nos galpões estudados, situados em Itaberaí, GO, foram avaliadas quatro variáveis térmicas (temperatura, índice de temperatura de globo negro e umidade, carga térmica de radiação e entalpia), três respostas fisiológicas (temperaturas retal e da pele, e frequência respiratória) e três índices de desempenho produtivo (ganho de peso, consumo de ração e conversão alimentar) das aves. Os resultados indicaram que os sistemas avaliados não foram suficientemente adequados para promover condições de conforto às aves, não sendo observada diferença estatística significativa entre o desempenho das aves neles alojados. A taxa de mortalidade no galpão SRSN foi 15 por cento maior em relação ao galpão SRPN, porém, ambas são inferiores àquelas sugeridas para as aves em estudo.

The main goal of this study was to evaluate the environmental conditions inside two commercial broiler houses equipped with different cooling systems: wet cellulose pads associated with misting (SRPN) and wet black screen pads associated with misting (SRSN). In the studied broiler houses, located in Itaberaí, Goiás, Brazil, four thermal variables (temperature, black globe temperature and humidity indices, thermal radiation load and enthalpy), three physiological responses (rectal temperature, skin temperature and respiration frequency), and three productivity performance indexes (weight gain, feed intake and feed conversion) for broiler chickens were evaluated. The results indicate that the evaluated systems were not sufficient to promote thermal comfort conditions for the birds and in general, no significant statistical difference was noticed between the performances of the birds raised in the two broiler houses. The mortality rate in the SRSN system was 15 percent higher than in the SRPN system, however, both are lower than those suggested for the birds under study.
