Leptospirosis is one of the most common zoonotic diseases in the world and endemic in the Caribbean Islands. Bovine leptospirosis is an important reproductive disease. Globally, cattle are recognized as a reservoir host for serovar Hardjo, which is transmitted urine, semen, and uterine discharges, and can result in abortion and poor reproductive performance. The dairy industry in Puerto Rico comprises up to 25% of agriculture-related income and is historically the most financially important agricultural commodity on the island. In this study, we report the isolation of two different pathogenic species, from two different serogroups, from urine samples collected from dairy cows in Puerto Rico: serogroup Sejroe serovar Hardjo and serogroup Pyrogenes. Recovered isolates were classified using whole-genome sequencing, serotyping with reference antisera and monoclonal antibodies, and immunoblotting. These results demonstrate that dairy herds in Puerto Rico can be concurrently infected with more than one species and serovar of , and that bacterin vaccines and serologic diagnostics should account for this when applying intervention and diagnostic strategies.

Plant botanical extracts are recognized for being a source of biologically active phytochemicals that potentially have diverse applications. The phytochemical composition, potential cytotoxicity, and insecticidal effectiveness of three leaf extracts from the folkloric medicinal plant L. (Calophyllaceae) were investigated.

Purpose: The prevalence of obesity, a crucial risk factor for breast cancer, is markedly higher among Hispanic women. The interaction between ethnic enclaves and neighborhood socioeconomic status (SES) as a determinant of this disparity warrants further research. We aimed to identify neighborhood profiles based on ethnic enclaves and socioeconomic status to evaluate the association with obesity among Hispanic women in the metropolitan Chicago region.

Background: Dengue virus, a major global health threat, consists of four serotypes (DENV1-4) that cause a range of clinical manifestations from mild to severe and potentially fatal disease.
Methods: This study, based on 19 years of data from the Pediatric Dengue Cohort Study and Pediatric Dengue Hospital-based Study in Managua, Nicaragua, investigates the relationship of serotype and immune status with dengue severity. Dengue cases were confirmed by molecular, serological, and/or virological methods, and study participants 6 months to 17 years old were followed during their hospital stay or as ambulatory patients.

Autonomic dysfunction is a common and early complication among patients with systemic sclerosis, suggesting that it may play a role in the pathogenesis of the disease and be a potential target for therapeutic interventions. Although the true prevalence of autonomic dysfunction among patients with systemic sclerosis is still unclear, it is estimated that as many as 80% of patients may be affected. Autonomic dysfunction may lead to widespread multi-organ dysfunction through its effects on the cardiovascular system, gastrointestinal tract, urinary tract, sweat and salivary glands, and pupils.
