“…A maioria dos óbitos ocorreram anteparto, tendo como umas das principais causas uma assistência inadequada a mulher gestante (Vieira;Kale;Fonseca, 2020). Diante disso, há uma necessidade de melhoria na assistência pré-natal, qualificação de profissionais e ao acesso aos cuidados realizados em todos os âmbitos para minimizar os riscos para a gestante e para o feto.…”

O óbito fetal é a expulsão ou extração completa do concepto pelo útero da mãe, possuindo peso superior ou igual a 500 gramas, ou idade gestacional maior que 22 semanas e/ou altura de 25 centímetros. No ano de 2020, cerca de 2,3 milhões de fetos foram à óbito no mundo. Devido ao grande número de morte fetal, é considerado um problema de saúde pública que necessita de uma análise criteriosa do perfil para compreensão dos fatores relacionados à ocorrência da mesma. O presente estudo busca caracterizar o perfil epidemiológico dos óbitos fetais no Estado do Piauí entre 2017 a 2021. Trata-se de um estudo epidemiológico descritivo, retrospectivo e quantitativo. Os dados foram retirados do Departamento de Informática do Sistema Único de Saúde (DATASUS) em novembro de 2023. Após a coleta dos dados, os mesmos foram dispostos em uma planilha do software Excel para análise e aplicação dos métodos estáticos tanto descritivos, como inferenciais. Entre os anos de 2017 a 2021 foram notificados 2.915 óbitos fetais no estado do Piauí, sendo mais frequente no ano de 2017 com 22,3% (n=650), na faixa-etária de 20 a 29 anos 40,85% (n=1191), de cor ou raça ignorada, com escolaridade de 8 a 11 anos estudados 36,5% (1065), tendo como local de ocorrência os hospitais 92,76% (n=2704). Uma prevalência maior de óbitos fetais tendo como causa as afecções originadas no período perinatal entre a 37 a 41 semanas (n=741), nesse período as gestantes acabam apresentando complicações que muitas vezes estavam silenciadas durante toda a gestação. Observa-se uma correlação não significante (p=0,220) entre o tipo de parto e idade materna, com a prevalência de gestantes na faixa etária de 20 a 29 anos 26,80% (n=781) e no período antes do parto 61,54% (n=1.794), que pode estar relacionado à falta de atenção dos profissionais para identificação precoce dos riscos da gestação. O Estado do Piauí, apesar dos objetivos traçados pela OMS ainda continua apresentando um elevado número de casos de óbitos fetais, sendo um problema de saúde que necessita de intervenções e mudanças de práticas tanto dos gestores como dos profissionais visando modificar o cenário em que se encontra.

“…The highest AST average was observed between 10:00 am and 1:00 pm, with 33.9 and 34.3°C, respectively, concomitant with the highest BGTHI average at 1:00 pm, with a value of approximately 80. For Vieira et al (2021) and Rodrigues et al (2021), the surface temperature depends directly on the environment's conditions: sudden changes in the meteorological variables in the place where the animal is found results in changes in the surface temperature. Similar results were obtained by Nascimento, Pereira, Nâãs, and Rodrigues (2011), who found a decrease in surface temperature with increasing age in male broilers raised under natural conditions of temperature and humidity.…”

The objective of this study was to evaluate the effect of threonine:digestible lysine ratio in the diet on the physiological variables and weight of organs of light laying hens. Two hundred and ten 47 week-old Dekalb White laying hens were distributed in a completely randomized design, with five levels of threonine (0.507; 0.552; 0.597; 0.642 and 0.677%) and seven replicates of six birds each. The experimental period was 10 weeks, totaling 62 days and more eight days for the animals to adapt. The physiological parameters of cloacal temperature (CT), respiratory rate (RR) and average surface temperature (AST) were recorded weekly (7:00 am, 10:00 am, 1:00 pm, 4:00 pm, and 7:00 pm); after solid and water fasting, the birds were slaughtered to assess the absolute weight of the organs. The time of day influenced (p < 0.05) the physiological parameters RR and AST, and CT showed a significant effect (p < 0.05) of increasing levels of digestible threonine. The total weight of the pancreas, proventriculus and lung showed a significant effect (p < 0.05) of the increase in the levels of digestible threonine. The respiratory rate is affected by the levels of threonine in the diet. The 0.687% level promoted hypertrophy of the pancreas, proventriculus and lung, promoting more significant activity of these organs.

“…With the importance that animal welfare has assumed in the most diverse fields of animal production and also in scientific research in the area, the use of non-invasive techniques and equipment has become essential. Infrared thermography technology is a non-invasive method used to indicate thermal biometric changes in animal metabolism, resulting from increased body temperature, surface temperature and changes in blood flow in response to environmental or physiological conditions, and is capable of detecting minimal variations in surface temperature and its gradientes (Souza Junior et al, 2013a;Vieira et al, 2022). When an animal becomes stressed, the hypothalamic-pituitary-adrenocortical axis is activated and heat is produced as a result of increased concentrations of catecholamines and cortisol, as well as blood puff responses, producing changes in the animal's heat production and loss (Silva et al, 2022).…”

The aim of this research was to evaluate the surface temperature and sensible heat emission of Japanese quails kept in a climate chamber at different temperatures: 24.0, 27.0, 30.0 and 33.0°C. The surface temperature was obtained using thermographic images collected in five regions (head, wings, back, legs and crest), calculating the average surface temperature (ST), the gradient between ST and air temperature (AT) and heat emissions by convection and radiation. The experimental design used was entirely randomised, with four treatments and six replications. Surface temperature in all regions of the birds' bodies and ST rose as air temperature rose, and the gradient between ST and AT decreased as AT rose, a fact which can make it difficult for the animals to exchange sensible heat with the environment. The crest and feet had the highest and lowest ST values, respectively. The heat emitted by the birds through convection and radiation decreases as the ambient temperature rises, and of the total heat emitted, there was a predominance of convection.
