Sero-prevalence and risk factors of leptospirosis in commercial cattle herds of Rupandehi district, Nepal

AbstractNepal has an agrarian-based economy where the livestock sector contributes about 12 percent to the national GDP. Rupandehi district is one of the largest dairy pocket areas in the nation, but the disease, such as leptospirosis, posed a negative impact on their production and productivity. Despite the economic importance of cattle leptospirosis, the disease is concerned for the people’s occupational risk and food safety. Although leptospirosis is a priority zoonosis in Nepal, the effective implementation of the control program lacks both in animal and human health. A cross-sectional study was conducted to estimate the prevalence and identify associated risk factors of cattle leptospirosis from March 2019 to April 2020. Altogether, 206 cattle herds located in all the sixteen local levels of the district were visited. The owners were interviewed to record the cattle management system’s information and their knowledge of the zoonotic diseases. A total of 383 cattle serum samples were collected, and an indirect antibody ELISA was performed to estimate the infection status of leptospirosis in the cattle herds. All the data were analyzed by Open epi and R software for the descriptive and analytical study. Bivariate and multivariable logistic regression was applied to assess the potential herd level and animal level risk factors. Out of seven potential herd-level risk factors, the purchased cattle herds (OR: 7.2, 95% CI: 1.24-136.5, p=0.025) and cattle with herd size >10 (OR: 14.92, 95% CI: 2.61-283.38, p=0.025) were identified as significant risk factors for leptospirosis. At the animal level, the cattle taken for grazing in pastureland accessed by the community dog was a significant risk factor (OR: 4.16, 95% CI: 1.13-14.06, p=0.034). Surprisingly, none of the farmers had heard about leptospirosis before. The outcome of this research could be an epidemiological insight in control of priority zoonosis to protect the livestock economy and reduce their negative impact on public health.

Abstract Background Brucellosis is a zoonotic disease caused by Brucella spp. In Nepal, the presence of brucellosis in small ruminants, namely sheep and goats, has impacted farmers’ livelihood and the food safety of consumers. A cross-sectional study was conducted in Rupandehi district of Nepal during January to March 2020 to investigate the seroepidemiology and associated risk factors of brucellosis in the sheep and goat population. Altogether, 19 sheep and 60 goat farms in the district were visited. Owners were interviewed to get information on animals, including their management and movement patterns. Three hundred fifty-seven samples (80 sheep and 277 goat samples) were collected proportionately based on farm sizes. Each serum sample was tested with Rose Bengal Test and ELISA to estimate the seropositivity of brucellosis. Logistic regression was carried out to calculate corresponding odds ratios of each variable associated with detection of brucellosis. Results At the farm level, 31.6% (6/19; 95% CI: 12, 54%) of sheep farms and 3.3% (2/60, 95% CI: 0.9, 11.4%) of goat farms were seropositive to brucellosis. Out of 80 sheep serum samples, 12 (15%; 95% CI: 8.79–24.41%) and out of 277 goat serum samples, three (1.1%; 95% CI: 0.37–3.14%) were seropositive to brucellosis. Age greater than 1.5 years (OR = 5.56, 95% CI: 1.39, 29.38; p = 0.02) and herd size of greater than 100 (OR = 4.74, 95% CI: 1.23, 20.32, p = 0.03) were identified as significant risk factors for seropositivity of brucellosis in the sheep population. While in the goat population, none of the variables was identified as a significant risk factor. Conclusion The study provides evidence that the older sheep and the sheep from the large herds were at higher risk of brucellosis. A control program should be put in place immediately in the sheep population because they may transmit infections to other livestock as they were regularly moved for grazing and selling purposes. Also, strict biosecurity measures should be implemented among pastoralists to prevent brucellosis transmission in them. We suggest further one health-based study to reveal the transmission dynamics of brucellosis between animals and humans.

Intestinal parasitic infections are common among children worldwide. This study was aimed at determining risk factors for infection with soil transmitted helminths, Cryptosporidium spp., and Giardia duodenalis, among children in preschools. The study was in two parts: a cross-sectional study in which data were collected from 403 children from 10 preschools and a longitudinal study in which 100 children from four preschools from the previous 10 were selected. Prevalence of Ascaris lumbricoides was 12.0%, while that of hookworm was 8.3%. Overall prevalence of Cryptosporidium and G. duodenalis was 28.0% and 29.0%, respectively. Low education level of parent/guardian was a significant risk factor for A. lumbricoides (OR = 2.35, 95% CI: 1.02–5.41; P=0.04), while roofing types other than corrugated iron sheets were found to be protective for G. duodenalis infection in both bivariate and multivariate analyses (multivariate: OR = 0.67, 95% CI: 0.45–0.99; P=0.04). Low socioeconomic level was found to be protective for Cryptosporidium spp. infection in multivariate analysis (OR = 0.59, 95% CI: 0.35–0.99; P=0.04). In the longitudinal study, none of the factors were associated with either infection. These findings may have implications for other preschools in other districts in Zambia.

Background Thrombocytopenia is the most common hematological abnormality in the neonatal period. Hemorrhagic manifestations are found in 10% cases of thrombocytopenia. Neonatal thrombocytopenia commonly assumed due to sepsis, despite many risk factors that may caused thrombocytopenia.Objective To obtain incidence and risk factors of neonatal thrombocytopenia.Methods A cross sectional study was conducted in April 2009. Complete blood counts investigation was performed before age of 24 hours, medical conditions and risk factors of mothers and subjects were noted, as well as hemorrhagic manifestations. Subjects with thrombocytopenia were followed for 2 weeks. The risk factors consisted of hypertension in pregnancy, pre-eclampsia, eclampsia, intrauterine growth retardation, gestational diabetes mellitus, perinatal infection, asphyxia, sepsis, and necrotizing enterocolitis.Results Neonatal thrombocytopenia was found 17 (12.1%) of 140 subjects, consisted of 88.2% early onset and 11.8% late onset. Significant risk factor of mother was pre-eclampsia (PR 3.97, 95%CI 1.70 to 9.25), while significant risk factors of neonates were asphyxia (PR 5.66, 95%CI 2.49 to 12.86), sepsis (PR 5.33, 95%CI 2.33-12.19) and necrotizing enterocolitis (p=0.014; PR 9.2 95% CI 5.17 to14.84). We found 29.4% hemorrhagic cases of neonatal thrombocytopenia (i.e.,. skin, gastrointestinal, intracranial hemorrhage).Conclusions The incidence of neonatal thrombocytopenia was 12.2%. Significant risk factor of mother that caused thrombocytopenia was pre-eclampsia, while risk factors of neonates were asphyxia, sepsis and necrotizing enterocolitis.[Paediatr Indones. 2010;50:31-7].

Animal agglomerations at commercial events such as trade fairs represent an important facilitator in infectious disease transmission. Thus, it is crucial to understand the epidemiology of infectious diseases in small ruminants. The objective of this study was to examine lentiviral presence in goats and sheep traded at the animal fair of Tabira city (Sertão region of Pernambuco) and identify possible risk factors associated with infection. We collected serum samples from 233 crossbred goats and 119 crossbred sheep, belonging to 12 breeders, at the Tabira livestock fair from November 2014 to June 2015. An epidemiological questionnaire was used to analyze the risk factors. Agar gel immunodiffusion (AGID) and western blotting (WB) were performed to diagnose small ruminant lentivirus (SRLV) infection. In the AGID test, we used maedi-visna virus (MVV) antigens for sheep and caprine arthritis/encephalitis virus (strain Cork) (CAEV-Co) antigen for goats. The WB analysis used CAEV-Co antigen for both species. Variables from the questionnaire were analyzed with univariate and multivariate statistics. One seropositive goat but no sheep was identified via AGID. According to the WB results, 15/233 goats (6.44%; CI95% = 3.94 - 10.35%) and 8/119 sheep (6.72%; CI95% = 3.45 - 12.71%) were seropositive, totaling 23/352 reactive animals (6.53%; CI95% = 4.39 - 9.61%) from 12 herds. Annual vermifugation of the animals was a significant risk factor (odds ratio = 5.9; CI95% = 1.7-19.8; p = 0.04) for disease in goats, but no variables associated with infection risks were identified in sheep. We concluded that SRLV was present in goats and sheep at the animal fair. Western blots were more sensitive than AGID for SRLV diagnosis. Practices aiming to improve sanitary management may reduce the risk of infection in goats. All studied herds included animals identified as seropositive for SRLV. Therefore, we recommend adopting measures that increase disease diagnosis while intensifying traffic control and surveillance of animal agglomerations.

This cross-sectional study was conducted to evaluate the individual awareness, related risk factors and complications of diabetes with socio-demographic profiles of the study individuals in Noakhali region, Bangladesh during June to December, 2013. A total 250 participants were selected randomly and data were collected using structured questionnaire. Among the respondents 47.20% were found male and 52.80% were female and majorities (52.00%) of the respondents were urban people. Respondents completed secondary study level or below were the dominant group. 9.20%, 27.20%, 12.80% and 34.40% respondents were agriculturist, businessman and housewives respectively. Women showed better knowledge about overall diabetes (20.00%) and blood glucose level (9.60%), in case of causes, symptoms and management men (12.80%, 23.20% and 18.40% respectively) were found dominant than women (10.00%, 16.00% and 12.00% respectively). It was found that 13.20% respondents were suffering from impaired glucose tolerance and 79.20% had diabetes mellitus where female were more vulnerable than male. Family history was found the significant risk factor (p= 0.016; Ç2 = 5.849) for diabetes (total 62%, male 40.65% and female 59.35%), Other risk factors like age (67.20%), obesity (46.40%), hypercholesterolemia (82.00%), excess triglyceride (78.00%) and hypertension (29.60%) remained insignificant respectively and in every cases female were found more vulnerable than men. Study revealed that knowledge regarding diabetes was not up to the mark to the respondents though it is now one of the most pandemic diseases in the world.Bangladesh J Medicine Jan 2016; 27(1) : 8-15

Abstract Background: A cross-sectional study was undertaken in Australia to explore a wide range of risk factors associated with keratoconus. A questionnaire addressing age, gender, educational background, ocular and medical history, smoking and alcohol consumption, and physical examination comprising anthropometric measurements was collected; eye examination was undertaken. The associations between a range of risk factors and keratoconus was determined using univariate and multivariable linear regression analyses.Main Text: A total of 260 keratoconus subjects were included in this study. Mean age of subject was 35.5 (SD= 14.8) years and the majority of the subjects were European 171 (68.2%). Initial univariate regression analysis identified the following risk factors at the p<0.1 level with keratoconus: higher body mass index, smoking cigarettes, diabetes, rheumatoid arthritis and asthma were associated with increased severity of keratoconus, whereas eczema was associated with less severe keratoconus. Following multivariable regression analysis, only asthma remained as a significant risk factor associated with 2.2 diopters (D) steeper average mean keratometry compared to keratoconus subjects having no asthma [p = 0.03; β= 2.18; 95% confidence intervals: 1.22, 4.14].Conclusion: Our study describes the comprehensive assessment of all the known risk factors in a large keratoconus cohort recruited in Australia. Our study has reported asthma as the only risk factor found to be significantly associated with keratoconus. The results of this study allow us to better understand the aetiology of keratoconus and such a knowledge could be useful in instigate systemic management of patients to slow or prevent keratoconus.

SummaryThe practice of dowry is widespread in India and refers to the payment of cash/gifts by the bride's family to the bridegroom's family before marriage. Though prohibited by law, dowry is widely practised, and often contributes to severe injuries and even death of young brides. This study examined the prevalence and risk factors for dowry demand and dowry harassment and its psychosocial correlates across different social strata in India, and also by husband and mother-in-law characteristics. In a cross-sectional survey of 9938 women in rural, urban and urban non-slum sites across India conducted in 1998–99, dowry demand was found to be significantly higher (p<0.001) in the urban non-slum and rural areas (26% and 23% respectively) than in urban slum areas (18%). Overall, 17% of groom's families were not satisfied with the dowry, this being higher in rural areas (21%) than in urban slum and non-slum areas (about 14% in both). The overall prevalence of dowry harassment among this group of women was 13.3%. Mothers-in-law who had themselves experienced dowry demand were 14 (95% CI 5.0–40.4) and 5 (95% CI 1.3–18.9) times more likely to demand and harass daughters-in-law over dowry, respectively. Another significant risk factor for dowry-related harassment was mother-in law's status in the family. Interventions related to modifiable risk factors, such as increased social support at the community level, should help reduce dowry harassment.
