Microgeographical Variation in Prevalence in Dogs in Suburban and Urban Areas of Rio De Janeiro, Brazil.

Dirofilariosis, a mosquito-borne disease caused by and , affects canids, felids and occasionally humans. Recent evidence suggests that prevalence is rising in the canine populations in several areas of Brazil, even those historically considered to be non-endemic, highlighting the need for ongoing surveillance. However, prevalence studies are frequently based on inference from single diagnostic methods, and it is acknowledged that this may lead to biases and an underestimation of the disease situation.

Evaluating the tolerance of harmful algal bloom communities to copper.

Harmful algal blooms (HABs) cause severe economic and environmental impacts, including hypoxic events and the production of toxins and off-flavor compounds. Chemical treatments, such as copper sulfate pentahydrate (CuSO·5HO), are often used to mitigate the damaging effects of algal blooms. However, treatment effects are usually short-lived leading to waterbodies requiring repeated CuSO·5HO applications to control persistent algal blooms, particularly in highly eutrophic systems, such as aquaculture ponds or small agricultural impoundments.

New Directions For Women's Health: Expanding Understanding, Improving Research, Addressing Workforce Limitations.

In the United States, the field of women's health faces critical challenges. This article, part of the National Academy of Medicine's Vital Directions for Health and Health Care: Priorities for 2025 initiative, emphasizes the need for a holistic, lifespan approach to women's health that considers biological sex, gender, and intersecting social factors. We identify three key challenges: broadening the understanding of women's health beyond reproductive issues, improving the research ecosystem, and addressing workforce limitations.

SMAD4 and KRAS Status Shape Cancer Cell-Stromal Crosstalk and Therapeutic Response in Pancreatic Cancer.

Pancreatic ductal adenocarcinoma (PDAC) contains an extensive stroma that modulates response to therapy, contributing to the dismal prognosis associated with this cancer. Evidence suggests that PDAC stromal composition is shaped by mutations within malignant cells, but most previous work has focused on pre-clinical models driven by KrasG12D and mutant Trp53. Elucidation of the contribution of additional known oncogenic drivers, including KrasG12V mutation and Smad4 loss, is needed to increase understanding of malignant cell-stroma crosstalk in PDAC.

Unmet needs and lived experience of patients receiving CAR T-cell therapy.

Chimeric Antigen Receptor T-Cell (CAR-T) therapy is an effective therapy and promising frontier in the treatment of hematologic malignancies. However, this revolutionary treatment has led to new challenges for patients, caregivers, and the healthcare system. In this review article, we discuss the various difficulties patients face both in the acute and long-term period following CAR-T infusion.
