- ItemRisk Factors Associated With Mastitis in Smallholder Dairy Farms in Southeast Brazil(MDPI (Basel, Switzerland), 2021-07-14) Silva AC; Laven R; Benites NR; Persson Y; Rahman MMThe aim of this study was to investigate the potential risk factors for clinical and subclinical mastitis in smallholder dairy farms in Brazil. A prospective, repeated cross-sectional study was carried out between May 2018 and June 2019 on 10 smallholder dairy farms. Potential risk factors for subclinical and clinical mastitis at the herd and cow level were recorded through interviewing the owner and by observation. A combination of clinical udder examination and the Tamis (screened mug with a dark base) test (Tadabras Indústria e Comércio de Produtos Agrovetereinário LTDA, Bragrança Paulista, SP, Brazil) were applied to observe clinical mastitis, and the California Mastitis Test (Tadabras Indústria e Comércio de Produtos Agrovetereinário LTDA, Bragrança Paulista, SP, Brazil) was used to determine subclinical mastitis. A total of 4567 quarters were tested, 107 (2.3%) had clinical mastitis, while 1519 (33.2%) had subclinical mastitis. At the cow level, clinical mastitis risk was highest in mid-lactation (50-150 days in milk) with OR 2.62 with 95% confidence interval (CI) of 1.03-6.67, while subclinical mastitis was highest in late lactation (> 150 days in milk) with OR 2.74 (95% CI 2.05-3.63) and lower in primiparous (OR 0.54, 95% CI 0.41-0.71) than multiparous cows. At the herd level, using dry-cow treatment (OR 4.23, 95% CI 1.42-12.62) was associated with an increased risk of clinical mastitis. Milking clinical (OR 0.37, 95% CI 0.24-0.56) and subclinical cases last (OR 0.21, 95% CI 0.09-0.47) and cleaning the milking parlor regularly (OR 0.27, 95% CI 0.15-0.46) had decreased odds for subclinical mastitis, while herds with optimized feed had greater odds (OR 9.11, 95% CI 2.59-31.9). Prevalence of clinical mastitis was at its lowest at the first visit in June/July and highest at the last visit in April/June (OR 3.81, 95% CI 1.93-7.52). Subclinical mastitis also presented increased odds in the last visit (OR 2.62, 95% CI 2.0-3.36). This study has identified some risk factors for mastitis on smallholder farms but further research on more farms across more areas of Brazil is required to develop a targeted mastitis control program for smallholder farms.
- ItemThe United Nations (UN) Card, Identity, and Negotiations of Health among Rohingya Refugees(MDPI (Basel, Switzerland), 2023-02-15) Rahman MM; Dutta MJ; Plaza Del Pino FJ; Ugarte-Gurruxaga MIBeing persecuted and expelled from Myanmar, Rohingya refugees are now distributed throughout the world. The Southeast Asian nation of Malaysia has been a preferred destination for Rohingyas fleeing Myanmar's state-sponsored genocide and more recently in a bid to change their fates from the refugee camps in Bangladesh. Refugees are one of the most vulnerable groups in Malaysia and often face dire circumstances, in which their health and wellbeing are compromised. Amidst a plethora of structural challenges, Rohingya refugees try to claim some of their rights with the aid of the UN card (UNHCR ID cards) in Malaysia. Guided by the culture-centered approach (CCA), this study examined the perspectives and experiences of healthcare among Rohingya refugees while living in Malaysia, now resettled in Aotearoa, New Zealand. The participants' narratives showed that the UN card not only materialized their refugee status in Malaysia but also offered them a way of living in a world where documents anchor the materiality of health.
