Advancing Nanotechnology: Targeting Biofilm-Forming Bacteria with Antimicrobial Peptides.

Nanotechnology offers innovative solutions for addressing the challenges posed by biofilm-forming bacteria, which are highly resistant to conventional antimicrobial therapies. This review explores the integration of pharmaceutical nanotechnology with antimicrobial peptides (AMPs) to enhance the treatment of biofilm-related infections. The use of various nanoparticle systems-including inorganic/metallic, polymeric, lipid-based, and dendrimer nanostructures-provides promising avenues for improving drug delivery, targeting, and biofilm disruption.

Gestational autoantibody exposure impacts early brain development in a rat model of MAR autism.

Maternal autoantibody-related autism (MARA) is a subtype of autism characterized by the maternal production of specific patterns of autoantibodies during pregnancy, which significantly increases the likelihood of an autism diagnosis in their children. Multiple patterns of MARA autoantibodies (MARA-ABS) have been identified, and differences in the severity of the autism phenotype associated with each autoantibody pattern have been described. In this study, we utilized preclinical rat models to further elucidate the differential effects of MARA-AB exposure based on the known clinical patterns, including the originally reported pattern of lactate dehydrogenase A and B (LDHA/B) + collapsin response mediator protein 1 (CRMP1) + stress-induced phosphoprotein 1 (STIP1), as well as the more recently described patterns of CRMP1+CRMP2, CRMP1 + guanine deaminase (GDA), and STIP1+ neuron-specific enolase (NSE).

Rate estimation and trend analysis of new HIV infections among the international migrant population in Chile from 2013 to 2022.

Background: International migrants are central to HIV research, but comparative data on their infection rates versus resident populations, including in Chile, are scarce. This study compares HIV incidence rates between international migrants and Chileans.

Methods: A longitudinal study was conducted.

The Association of Food Security With Hypertensive Disorders of Pregnancy: A National Health Interview Survey Analysis.

Food security is one of the most researched social determinants of health (SDoH), however, there is a lack of literature on the impact of food security on cardiovascular disease in pregnancy. The primary objective was to examine the association between food security with hypertensive disorders of pregnancy. We performed a cross-sectional analysis of 2019-2022 data from the National Health Interview Survey.

Neighborhood disadvantage and general anesthesia utilization in cesarean delivery: a retrospective analysis.

Background: Neighborhood disadvantage, a social driver of health (SDOH), has been associated with adverse perinatal outcomes; yet little is known about its association with anesthetic choice.

Objective: The purpose of this study is to assess the association of neighborhood disadvantage and anesthetic choice for cesarean deliveries. We hypothesize that people from the most disadvantaged neighborhoods are more likely to receive general anesthesia for cesarean deliveries compared to those from the most advantaged neighborhoods.
