Repellent activity of essential oils to the Lone Star tick, Amblyomma americanum

The Lone Star tick, Amblyomma americanum is important to human health because of a variety of pathogenic organisms transmitted to humans during feeding events, which underscores the need to identify novel approaches to prevent tick bites. Thus, the goal of this study was to test natural and synthetic molecules for repellent activity against ticks in spatial, contact and human fingertip bioassays.

Effectiveness of the fourth dose of COVID-19 vaccines against severe COVID-19 among adults 40 years or older in Brazil: a population-based cohort study

The emergence of COVID-19 variants with immune scape and the waning of primary vaccine schemes effectiveness have prompted many countries to indicate first and second booster COVID-19 vaccine doses to prevent severe COVID-19. However, current available evidence on second booster dose effectiveness are mostly limited to high-income countries, older adults, and mRNA-based vaccination schemes scenarios.

Perspectives Among Health Care Providers and People with HIV on the Implementation of Long-Acting Injectable Cabotegravir/Rilpivirine for Antiretroviral Therapy in Florida

Long-acting injectable (LAI) cabotegravir/rilpivirine (CAB/RPV) for antiretroviral therapy (ART) could benefit many people with HIV (PWH). However, its impact will largely be determined by providers’ willingness to prescribe it and PWH’s willingness to take it. This study explores the perceived barriers and facilitators of LAI CAB/RPV implementation among PWH and HIV care providers in Florida, a high prevalence setting.

New Genotypes of Phytophthora nicotianae Found on Strawberry in Florida

Phytophthora cactorum is the most common causal agent of Phytophthora crown rot and leather rot of strawberry, but P. nicotianae is also responsible for the disease in Florida. Studies of P. nicotianae populations have suggested that different groups of genotypes are associated with different hosts; however, it is not yet clear how many lineages exist globally and how they are related to different production systems.
