Antibiotic resistance and biofilm formation in Klebsiella spp. isolates from Intensive Care Units in the Brazilian Amazon.

Klebsiella spp. is an opportunistic pathogen which poses a significant threat to public health, especially due to antimicrobial resistance and biofilm formation. This study aimed to determine the antibiotic resistance profile, biofilm formation and β-lactamases production in Klebsiella spp.

Nandrolone decanoate impairs gastrointestinal motility and duodenal morphometry in moderately exercised rats.

The misuse of anabolic androgenic steroid associated or not with physical workouts disrupts gastrointestinal (GI) function homeostasis. Our goal was to investigate the effects of nandrolone decanoate (ND) and moderate swimming on the GI transit of solid meals, GI motor contractility, and intestinal histology in rats. Male Wistar rats were allocated to four groups that received intramuscular injections of ND (5.

A New Murine Undernutrition Model Based on Complementary Feeding of Undernourished Children Causes Damage to the Morphofunctional Intestinal Epithelium Barrier.

Background: Complementary feeding is critical in establishing undernutrition. However, experimental undernourished diets do not represent the amount of nutrients in the complementary diets of undernourished children.

Objectives: To develop, validate, and evaluate the impact of a new murine model of undernutrition on the intestinal epithelium, based on the complementary diet of undernourished children from 7 countries with low-socioeconomic power belonging to the Malnutrition-Enteric Diseases (MAL-ED) cohort study.

'Children awaken by playing: a qualitative exploration of caregivers' norms, beliefs and practices related to young children's learning and early childhood development in rural Burkina Faso.

Introduction: Evidence suggests that responsive caregiving and early learning activities positively impact developmental outcomes, with positive effects throughout the life course. Early childhood development interventions should align with local values, beliefs and resources but there has been little research of caregiver beliefs and perspectives on development and learning, especially in sub-Saharan Africa. This qualitative study explored norms, beliefs, practices and aspirations around child development of caregivers of young children in rural Burkina Faso.

Combined antibiofilm activity of synthetic peptides and antifungal drugs against spp.

and are biofilm-forming drug-resistant yeasts that cause bloodstream infections that can lead to death. nystatin and itraconazole were combined with two synthetic peptides, PepGAT and PepKAA, to evaluate the synergistic effect against biofilms. Additionally, scanning electron and fluorescence microscopies were employed to understand the mechanism behind the synergistic activity.
