Sulfachloropyridazine (SCP) is an antimicrobial (AM) commonly used in the poultry industry. This drug is excreted as the original compound, which may accumulate in litter. This work was done to assess whether SCP residues from droppings of broiler chickens that were treated with therapeutic doses of this drug spread into the production environment and to determine if these events were associated with the selection of resistant bacteria.

October 2024
Habitat selection by aquatic organisms is dependent on the availability of adequate conditions to support life and the benefits that the habitat provides. Contaminated environments tend to be less attractive to organisms because reduced habitat quality leads to increased maintenance costs. Consequently, reduced colonization of such disturbed habitats is an expected response.

- Aquatic organisms like Daphnia magna rely on chemical cues in their environment for survival, and this study assessed their ability to avoid fipronil-contaminated areas after a short exposure to the insecticide.
- The HeMHAS system was used to evaluate the daphnids' swimming behavior and habitat preference, showing they favored less contaminated areas despite experiencing decreased swimming ability due to fipronil exposure.
- The research highlights the need for non-forced exposure methodologies in ecological studies, aiming to better understand the impact of contaminants on habitat selection and overall ecosystem health.
Effect of low dose Semaglutide in people with Type 1 Diabetes and excess weight.
Diabetes Res Clin Pract
March 2024
Obesity is a prevalent problem in people living with T1D (PwT1D), and it has been linked to cardiovascular disease in this population. The use of low dose weekly Semaglutide (0,5 mg) was evaluated in a cohort of PwT1D and excess weight.

Aims: The purpose of this study is to evaluate an AI software called RAPID NCCT Stroke (RAPID, iSchemaView, Menlo Park, CA) for ICH and LVO detection compared to expert readers.
