Risk factors associated with stillbirth in sows / Fatores de risco associados à natimortalidade em fêmeas suínas

In this study, the risk factors associated with stillbirth in sows were identified and their odds ratio assessed. For this purpose, 587 farrowings on Farm A and 929 on Farm B were monitored, and the sow parity, body condition score, farrowing duration, total number of piglets born, numbers of live births, stillbirths, and mummified piglets, obstetric interventions, and piglet sex and weight were recorded. At the end of farrowing, piglets classified as stillborn were necropsied to confirm the diagnosis. Consequently, 5.49% of the piglets on Farm A and 5.10% of those on Farm B were stillborn. On both farms, sows with a high parity, prolonged farrowing, and a large litter size had the highest odds ratio of stillbirths. On Farm B, farrowing intervention through the use of vaginal palpation and oxytocin increased the odds of stillbirth by 1.7 and 2.5 times, respectively. Heavy litters increased the odds of stillbirth by 1.4 times. Additionally, low-birth-weight piglets were 2.3 and 3.1 times more likely than their medium-birth-weight and high-birth-weight counterparts, respectively, to be stillborn. In conclusion, on both farms, the risk factors associated with stillbirth were a high parity, a large litter size, and prolonged farrowing.

O objetivo deste estudo foi avaliar os fatores de risco associados ao nascimento de natimortos em fêmeas suínas e a razão de chance para a sua ocorrência. Foram acompanhados 587 partos na granja A e 929 na granja B onde foram registrados: ordem de parto, escore de condição corporal, duração do parto, total de nascidos, nascidos vivos, natimortos, mumificados, intervenções ao parto, peso e o sexo dos leitões. Ao final do parto foi realizada necropsia dos leitões classificados como natimortos a fim de confirmar o diagnóstico. A ocorrência de leitões natimortos foi de 5,49% e 5,10% na granja A e B, respectivamente. Fêmeas de maior ordem de parto, com partos prolongados e leitegadas mais numerosas apresentaram maior chance da ocorrência de leitões natimortos em ambas as granjas. Na granja B a necessidade de intervenção ao parto através do uso de ocitocina e palpação vaginal aumentaram a chance da presença de leitões natimortos em 1,7 e 2,5 vezes, respectivamente. Leitegadas pesadas aumentaram em 1,4 vezes as chances de ocorrência de leitões natimortos. No entanto, leitões com menor peso ao nascer aumentam em 2,3 vezes as chances de natimortos, quando comparadas a leitões de peso intermediário, e 3,1 vezes em relação a leitões com maior peso de nascimento. Os fatores de risco associados à ocorrência de natimortos nas duas granjas foram a ordem de parto elevada, leitegadas numerosas e partos prolongados.

Evaluation of potential ecological risk assessment of toxic metal (lead) in contaminated meadows in the vicinity of suburban city: soil vs forages vs livestock / Avaliação de risco ecológico em potencial avaliação de metal tóxico (chumbo) em prados contaminados nas proximidades da cidade suburbana: solo x forragens x gado

Heavy metal toxicity is becoming an increasing concern for environmental, human and animal health. The current research analyzed the lead (Pb) contamination in the food chain under three different irrigation sources (ground, canal, and wastewater). Soil, plant and animal samples were collected from the Jhang district of Pakistan and processed with an atomic absorption spectrophotometer. Lead concentration varied in the samples as: 5.22-10.73 mg/kg in soil, 2.46-10.34 mg/kg in forages and 0.736-2.45 mg/kg in animal samples. The observed lead concentration in forage and animal blood samples was higher than the standard limits. The pollution load index (0.640-1.32) in soil showed that lead contamination mainly took place at the wastewater irrigating sites. Bio-concentration factor values (0.313-1.15) were lower than one in all samples except Zea mays, showing that lead metal was actively taken up by Zea mays tissues from the soil. Enrichment factor values ranged from 0.849-3.12, showing a moderate level of lead enrichment. Daily intake and health risk index varied between 0.004-0.020 mg/kg/day and 0.906-4.99, respectively. All the samples showed maximum lead concentration at the wastewater irrigating site compared to the ground or canal water application sites. These results recommended that consistent application of wastewater for forage irrigation must be avoided to prevent health hazards associated with lead in the animal and human food chain. Government must implement adequate strategies to protect the animal and human health from the harms of toxic heavy metals.

A toxicidade de metais pesados está se tornando uma preocupação crescente para a saúde ambiental, humana e animal. A pesquisa atual analisou a contaminação por chumbo (Pb) na cadeia alimentar sob três diferentes fontes de irrigação (solo, canal e águas residuais). Amostras de solo, plantas e animais foram coletadas no distrito de Jhang, no Paquistão, e processadas com um espectrofotômetro de absorção atômica. A concentração de chumbo nas amostras variou em: 5,22-10,73 mg/kg no solo, 2,46-10,34 mg/kg nas forragens e 0,736-2,45 mg/kg nas amostras de animais. A concentração de chumbo observada nas amostras de forragem e sangue animal foi superior aos limites padrão. O índice de carga de poluição (0,640-1,32) no solo mostrou que a contaminação por chumbo ocorreu principalmente em locais de irrigação de águas residuais. Os valores do fator de bioconcentração (0,313-1,15) foram menores que um em todas as amostras, exceto Zea mays, mostrando que o chumbo metálico foi ativamente absorvido pelos tecidos de Zea mays do solo. Os valores do fator de enriquecimento variaram de 0,849-3,12, mostrando um nível moderado de enriquecimento de chumbo. A ingestão diária e o índice de risco à saúde variaram entre 0,004-0,020 mg/kg/dia e 0,906-4,99, respectivamente. Todas as amostras mostraram concentração máxima de chumbo no local de irrigação de águas residuais em comparação com os locais de aplicação de água no solo ou no canal. Esses resultados recomendam que a aplicação consistente de águas residuais para irrigação de forragem deve ser evitada para evitar riscos à saúde associados ao chumbo na cadeia alimentar animal e humana. O governo deve implementar estratégias adequadas para proteger a saúde animal e humana dos danos dos metais pesados tóxicos.

Canine visceral leishmaniasis: risk factors and spatial analysis in an endemic area of Northeastern Brazil / Leishmaniose visceral canina: fatores de risco e análise espacial em uma área endêmica do Nordeste do Brasil

Canine visceral leishmaniasis is a disease caused by the protozoon Leishmania infantum, an important agent of zoonotic concern. In this study we determined the seroprevalence, risk factors and spatial distribution of infection by L. infantum among dogs in the Pajeú microregion of the Sertão region of Pernambuco, Brazil. Canine serum samples (n = 247) were tested using the Dual Path Platform (DPP®) rapid screening test and ELISA/S7® confirmatory test; and risk factors were assessed through univariate analysis and logistical regression. The spatial distribution of reactive dogs was analyzed by drawing a map using QGIS. Seroprevalence of 13.7% (34/247) was detected, with cases predominating in the municipality of Tabira (26.4%; 9/34). Age above 10 years was considered to be a risk factor associated with the presence of anti-L. infantum antibodies. The high overall prevalence and spatial distribution of positive cases showed wide dispersion of reagents dogs in the study area. Therefore, preventive measures are needed in order to reduce the risk of infection for animals and humans.(AU)

Leishmaniose Visceral Canina é uma doença causada pelo protozoário Leishmania infantum, importante agente zoonótico. O objetivo deste estudo foi determinar a soroprevalência, avaliar os fatores de risco e a distribuição espacial da infecção por L. infantum em cães da microrregião do Pajeú, Sertão de Pernambuco, Brasil. Amostras de soro canino (n=247) foram testadas ("Dual Path Platform Rapid Test" - TR DPP® (triagem); ELISA/S7 (confirmatório)), e os fatores de risco avaliados por meio de análise univariada e regressão logística. A distribuição espacial dos cães reagentes foi analisada por meio de mapas confeccionados no programa QGIS. Detectou-se soroprevalência de 13,7% (34/247), com predominância dos casos no município de Tabira (26,4%; 9/34). A idade acima de 10 anos foi considerada fator de risco associado à presença de anticorpos anti-L. infantum. A alta prevalência e distribuição espacial dos casos positivos revelou ampla dispersão de cães reagentes na área de estudo. Portanto, medidas preventivas são necessárias a fim de reduzir o risco de infecção para os animais e humanos.(AU)

Comparative Study on the Predominance of Lactobacillus spp. and Escherichia Coli in Healthy vs Colibacillosis Diseased Broilers

This study aims to identify relative proportions of beneficial and pathogenic bacteria in the gut of broilers and risk factors that may be contributing to the development of colibacillosis disease in broiler farms of District Kasur, Punjab, Pakistan. For this, 10 healthy and 10 colibacillosis affected broiler farms were surveyed for ileum and blood sample collection along with data regarding farm management, antibiotic use and hygiene practices. Lactobacillus and Escherichia coli number was estimated using Miles and Misra method and colibacillosis was confirmed by Congo red dye assay. Lactobacillus and E. coli were identified biochemically. For risk factors analysis chi-square analysis was performed to find any significant association between the health status of the farm and risk factors. Results showed during disease and healthy conditions Lactobacillus and Escherichia coli counts differ significantly (p<0.05). E. coli counts (106-108 to 107-109) increased (p<0.05) about three folds and Lactobacillus counts decrease (106-108 to 105-107) about four folds in disease conditions. Risk factor analysis showed colibacillosis disease was significantly associated (p<0.05) with non-vaccinated flocks, natural ventilation systems, rodent presence and the lack of outfit disinfection or change by workers when moving between different houses. It is concluded that E. coli and Lactobacillus work antagonistically to each other. However, further research is necessary to determine the exact mechanisms by which E. coli and Lactobacillus influence the development of colibacillosis. While Lactobacillus as probiotic may help with prevention, good hygiene and management practices are still crucial in preventing the spread of disease.(AU)

Trypanosoma evansi in horses from Colombia - associated infection factors

Background: Trypanosoma evansi is the most common protozoan in tropical and subtropical regions of the world, due to its ability to maintain and be transmitted by vectors such as Stomoxys spp. and Tabanus spp. This protozoan causes high morbidity and mortality rates in horses in African, American and Asian countries. In the years 2021 and 2022, a high mortality rate was reported among horses with symptoms associated with Trypanosoma spp. in the municipality of Arauca, department of Arauca, Colombia. The investigation described here was therefore carried out, seeking to identify the pathogens and risk factors that led to the death of the horses in this region of Colombia. Cases: Blood samples were collected from Colombian criollo horses and dogs, as were samples of ticks, flies and horseflies that infested the horses. A variety of tissue samples were removed from the horses a few min after their death for histopathological analysis. Two questionnaires were applied to obtain information about the horses and the environment in which they live. The results of the clinical examination revealed pale mucous membranes, jaundice, high fever, dehydration and lethargy. The horses were also infested with Amblyomma mixtum (17.6%) and Dermacentor nitens (82.4%) ticks, and with Tabanus pungens (74%), Tabanus spp. (26%), and Stomoxys calcitrans flies (100%), while the dogs were infested with Rhipicephalus sanguineus s.l. (77.7%) and Amblyomma mixtum (22.2%) ticks. The blood smear test results revealed the presence of Trypanosoma spp. in 66.6% (n = 4) of the horse blood samples, and in 50% (n = 1) of the dog blood samples. PCR performed to identify the Trypanosoma species confirmed the presence of T. evansi. Histological examination of the spleen revealed the involvement and dissemination of T. evansi in the tissues. The horses also showed the presence of Equine Infectious Anemia Virus (EIAV). Discussion: This is the first updated specific report of T. evansi in criollo horses in the savannah flood zone of the municipality of Arauca, Colombia. The main risk associated with T. evansi infection in horses was found to be infestation with the natural vector T. pungens and the mechanical vector S. calcitrans, which are efficient ectoparasites for the transmission of this parasite. The presence of T. evansi in dogs represents a constant risk to horses, because dogs may serve as a reservoir for the maintenance of the hemoparasite in the population under study. Another risk factor for horses could be the presence of vampire bats (Desmodus rotundus), a species of bat that has been described as a vector and reservoir of T. evansi in Colombia. The presence of EIAV antibodies in the horses under study can be attributed to the exposure of sick horses to vectors of this virus, such as Tabanus spp., S. calcitrans and inanimate needle-shaped fomites. This is the first study that identifies the coinfection of T. evansi and EIAV in horses in the floodplain region of Colombia. In view of the importance of these 2 pathologies to the health of horses, a greater number of tests and a larger animal population will be required to determine if this coinfection is the cause of the death of criollo horses in this region of Colombia. Lastly, the owners reported that pharmacological control with trypanocides has not been successful in most of the outbreaks that occurred during the years 2021 and 2022. This may suggest that Trypanosoma evansi is developing resistance to these drugs; therefore, specific studies will be required in the future to test this hypothesis.

Hyperhomocysteinemia as an Independent Risk Factor for Coronary Heart Disease. Comparison with Conventional Risk Factors / Hiper-homocisteinemia como fator de risco independente para doença coronariana: comparação com fatores de risco convencionais

Abstract The present study was designed to evaluate the strength of association of raised plasma homocysteine concentration as a risk factor for coronary heart disease independent of conventional risk factor. It was a case control study conducted at Punjab Institute of Cardiology Lahore. A total of 210 subjects aged 25 to 60 years comprising of 105 newly admitted patients of CHD as cases and 105 age and sex matched healthy individuals with no history of CHD as control were recruited for the study. Fasting blood samples were obtained from cases and controls. Plasma homocysteine was analyzed by fluorescence polarization immunoassay (FPIA) method on automated immunoassay analyzer (Abbott IMX). Total cholesterol, triglyceride and HDL cholesterol were analyzed using calorimetric kit methods. The concentration of LDL cholesterol was calculated using Friedewald formula. The patients were also assessed for traditional risk factors such as age, sex, family history of CVD, hypertension, smoking and physical activity, and were compared with control subjects. The collected data was entered in SPSS version 24 for analysis and interpretation.The mean age in controls and experimental groups were 43.00± 8.42 years and 44.72± 8.59 years with statistically same distribution (p- value= 0.144). The mean plasma homocysteine for cases was 22.33± 9.22 µmol/L where as it was 12.59±3.73 µmol/L in control group. Highly significant difference was seen between the mean plasma level of homocysteine in cases and controls (p˂0.001).Simple logistic regression indicates a strong association of coronary heart disease with hyperhomocysteinemia (OR 7.45), which remained significantly associated with coronary heart disease by multivariate logistic regression (OR 7.10, 95%C1 3.12-12.83, p=0.000). The present study concludes that elevated levels of Plasma homocysteine is an independent risk factor for coronary heart disease independent of conventional risk factors and can be used as an indicator for predicting the future possibility for the onset of CVD.

Resumo O presente estudo foi desenhado para avaliar a força da associação da concentração elevada de homocisteína no plasma como um fator de risco para doença cardíaca coronária independente do fator de risco convencional. Foi um estudo de caso-controle realizado no Punjab Institute of Cardiology Lahore. Um total de 210 indivíduos com idade entre 25 e 60 anos, compreendendo 105 pacientes recém-admitidos de CHD como casos e 105 indivíduos saudáveis ​​pareados por idade e sexo sem histórico de CHD como controle, foi recrutado para o estudo. Amostras de sangue em jejum foram obtidas de casos e controles. A homocisteína plasmática foi analisada pelo método de imunoensaio de polarização de fluorescência (FPIA) em analisador de imunoensaio automatizado (Abbott IMX). Colesterol total, triglicerídeos e colesterol HDL foram analisados ​​usando métodos de kit calorimétrico. A concentração de colesterol LDL foi calculada pela fórmula de Friedewald. Os pacientes também foram avaliados para fatores de risco tradicionais, como idade, sexo, história familiar de DCV, hipertensão, tabagismo e atividade física, e foram comparados com indivíduos de controle. Os dados coletados foram inseridos no SPSS versão 24 para análise e interpretação. A média de idade nos grupos controles e experimentais foi de 43,00 ± 8,42 anos e 44,72 ± 8,59 anos com distribuição estatisticamente igual (p-valor = 0,144). A homocisteína plasmática média para os casos foi de 22,33 ± 9,22 µmol / L, enquanto no grupo controle foi de 12,59 ± 3,73 µmol / L. Diferença altamente significativa foi observada entre o nível plasmático médio de homocisteína em casos e controles (p ˂ 0,001). A regressão logística simples indica uma forte associação de doença cardíaca coronária com hiper-homocisteinemia (OR 7,45), que permaneceu significativamente associada com doença cardíaca coronária por multivariada regressão logística (OR 7,10, 95% C1 3,12-12,83, p = 0,000). O presente estudo conclui que níveis elevados de homocisteína plasmática são fator de risco independente para doença cardíaca coronária, independentemente dos fatores de risco convencionais, e pode ser usado como um indicador para prever a possibilidade futura de aparecimento de DCV.

Seroprevalence and risk factors associated with leukosis in cattle from Villlavicencio, Colombia / Soroprevalência e fatores de risco associados à leucose em bovinos de Villlavicencio, Colômbia

Bovine leukosis is caused by an oncogenic virus of the genus Deltaretrovirus, causing losses associated with decreased production indicators and restrictions on exports of cattle and cattle products. The disease has a prolonged incubation period of between 1-5 years and the antibodies can be detected 2-3 weeks post infection. The disease can present asymptomatically, and develop persistent lymphocytosis or lymphosarcoma. The objective of this study was to estimate the prevalence and risk factors associated with bovine leukosis in Villavicencio, Colombia. Blood samples were taken from 636 animals, and obtained randomly from 24 herds. The samples were analysed using a Competition ELISA kit for the detection of anti-gp51 antibodies. Information on possible risk factors was collected, then OR and X2 were calculated, and statistically significant with p < 0.05 variables were included in a linear regression multivariate analysis. The general seroprevalence was 24.6% and the herd seroprevalence was 83.3%. The seroprevalence was 21.3% in males and 25.0% in females. The risk factors identified were abortion, non-bearing cows, artificial insemination, and use of common needles, Creole breed and participation in cattle exhibitions. The study confirmed the presence of bovine leukosis associated with reproductive and management factors.(AU)

Nutritional assessment of servicemen in relation to area of duty and feeding habits: a Pakistani prospective / Avaliação nutricional de militares em relação à área de dever e hábitos alimentares: uma perspectiva paquistanesa

The present study was carried out to determine incidence of overweight and obesity in Pakistani servicemen with reference to their area of duty, feeding habits and also to identify risk factors. Accordingly, 2,501 servicemen selected from all over Pakistan using multiple stage stratified sampling protocol. Nutrition assessment performed using body mass index (BMI), waist to hip ratio (WHR) and dietary assessment using food frequency questionnaire. Collected data was analyzed using the SPSS version 25. Regression was used to find risk factors of obesity and WHR. Results indicated that about 1/4th of servicemen were smokers. Approximately, 1/5th of them were overweight and about one quarter were eating fruits and vegetables for <3 days/ week and <4 days/week, respectively. Only 1/3rd of them were physically active for at least <40 minutes per day. Age and fruits intake were significantly predicting BMI with a direct relation and vegetable intake was negatively correlated to BMI of the servicemen. Age and rank were significant predictors of WHR while, physical activity was negatively correlated to WHR. It is concluded and suggested from our study that there is a need to modify eating patterns and habits as well as improving physical activity on daily basis for healthy and long life of the servicemen.

O presente estudo foi realizado para determinar a incidência de sobrepeso e obesidade em militares paquistaneses com referência à sua área de serviço, hábitos alimentares e também para identificar fatores de risco. Assim, 2.501 militares selecionados de todo o Paquistão usando protocolo de amostragem estratificada de múltiplos estágios. Avaliação nutricional realizada por meio do índice de massa corporal (IMC), relação cintura-quadril (RCQ) e avaliação alimentar por meio de questionário de frequência alimentar. Os dados coletados foram analisados por meio do SPSS versão 25. A regressão foi usada para encontrar fatores de risco para obesidade e RCQ. Os resultados indicaram que cerca de 1/4 dos militares eram fumantes. Aproximadamente, 1/5 deles estava com sobrepeso e cerca de um quarto comia frutas e vegetais por <3 dias / semana e <4 dias / semana, respectivamente. Apenas 1/3 deles era fisicamente ativo por pelo menos <40 minutos por dia. Idade e ingestão de frutas foram preditores significativos do IMC com uma relação direta e ingestão de vegetais foi negativamente correlacionada com o IMC dos militares. Idade e posição foram preditores significativos de RCQ, enquanto a atividade física foi negativamente correlacionada com RCQ. Conclui-se e sugere-se a partir de nosso estudo que há necessidade de modificar os padrões e hábitos alimentares, bem como melhorar a atividade física no dia a dia para uma vida longa e saudável dos militares.
