The severe surge of coronavirus disease 2019 (COVID-19) cases on the Indian subcontinent in early 2021 was marked by an unusually high number of COVID-19-associated mucormycosis (CAM) cases reported during this same period. This is significantly higher than predicted based on available data about prevalence and risk factors for this condition. This may be due to an unusual alignment of multiple risk factors for this condition. There is high background prevalence of mucormycosis in India likely from a high prevalence of risk factors, including undiagnosed or poorly controlled diabetes. COVID-19-induced immune dysregulation and immune suppression from steroid therapy increase the risk. The role of environmental exposure is unclear. System factors such as lack of access to healthcare during a pandemic may result in delayed diagnosis or suboptimal management with potentially poor outcomes. Here, we review currently identified risk factors and pathogenesis of CAM in a pandemic surge.

The protozoan parasite Neospora caninum is an important cause of abortion in cattle. Infection occurs horizontally by ingestion of oocysts shed by canids or vertically, from an infected dam to the foetus, and may result in abortion, stillbirth, or the birth of subclinically infected offspring. We estimated the occurrence of N.

Background: Real-world COVID-19 vaccine effectiveness (VE) studies are investigating exposures of increasing complexity accounting for time since vaccination. These studies require methods that adjust for the confounding that arises when morbidities and demographics are associated with vaccination and the risk of outcome events. Methods based on propensity scores (PS) are well-suited to this when the exposure is dichotomous, but present challenges when the exposure is multinomial.

Background: Research has shown that engaging in a range of healthy lifestyles or behavioral factors can help reduce the risk of developing dementia. Improved knowledge of modifiable risk factors for dementia may help engage people to reduce their risk, with beneficial impacts on individual and public health. Moreover, many guidelines emphasize the importance of providing education and web-based resources for dementia prevention.

Center for Management, University of Münster, Münster, Germany.
Background: Telemedicine is transforming health care by enabling remote diagnosis, consultation, and treatment. Despite rapid adoption during the COVID-19 pandemic, telemedicine uptake among health care professionals (HCPs) remains inconsistent due to perceived risks and lack of tailored policies. Existing studies focus on patient perspectives or general adoption factors, neglecting the complex interplay of contextual variables and trust constructs influencing HCPs' telemedicine adoption.
