AI Article Synopsis
- A study of 255 cattle farms in England and Wales aimed to identify risk factors for verocytotoxin-producing E. coli O157 (VTEC) among young cattle.
- Key findings indicated that farms with access to springs had a lower risk of VTEC infection, while less frequent checks of bedding wetness increased risk significantly.
- For young-stock housed in pens, factors like wet bedding, group size, and feeding straw were associated with a higher likelihood of VTEC presence.
Article Abstract
We conducted a cross-sectional study on 255 cattle farms in England and Wales to identify risk factors for verocytotoxin-producing E. coli O157 (VTEC). Exposure variables were collected at the levels of the farm and of the group of young-stock within the farms. On each farm a group of young-stock (6-18 months of age) was sampled to establish VTEC status. In our multiple logistic regression, farm VTEC status was associated with access to springs (OR: 0.31, CI95%: 0.12, 0.78) and assessing the wetness of the bedding material less frequently than daily (OR: 3.89 CI95%: 1.5, 10.2). At group-level we found no associated risk factors for animals housed outdoors in fields. Significant for groups housed in pens were wet bedding (wet OR: 3.43, CI95%: 1.3, 9.4; very wet OR: 4.24, CI95%: 1.2, 14.6), number of animals in the group (10-15 OR: 2.72, CI95%: 0.75, 9.9, 16-24, OR: 3.78, CI95%: 1.2, 12.3; >25 OR: 3.78, CI95%: 1.1, 12.7) and feeding straw (OR: 2.29, CI95%: 1.2, 5.5).

Among the most pressing problems societies face today are economic inequality and the erosion of democratic norms and institutions. In fact the two problems-inequality and democratic erosion-are linked. In a large cross-national statistical study of risk factors for democratic erosion, we establish that economic inequality is one of the strongest predictors of where and when democracy erodes.

Objective: Aneurysmal subarachnoid hemorrhage (SAH) is associated with high morbidity and mortality rates. In particular, functional outcomes of SAH caused by large or giant (≥ 10 mm) ruptured intracranial aneurysms are worsened by high procedure-related complication rates. However, studies describing the risk factors for poor functional outcomes specific to ruptured large/giant aneurysms are sparse.

Objective: To assess factors influencing Neonatal Respiratory Distress Syndrome (RDS) risk, incorporating maternal demographics, behaviors, medical conditions, pregnancy-related factors, and PM2.5 speciation pollutants exposures.
Methods: Using Florida de-identified birth records, logistic regression analyses were conducted to assess associations between maternal exposure to PM2.

Objective: Hand function, an important component of daily functioning, declines with age, yet the degree to which occupation modifies such declines is largely unknown.Methods: Older adults (≥65) completed an online cross-sectional survey containing a standardized hand function questionnaire, occupation-related questions, and demographic information. Participants were then categorized by their longest-held occupation as Blue Collar or White Collar.
