Unlabelled: To evaluate the accuracy of the lung ultrasound score (LUS) in predicting ventilatory weaning failure during neonatal hospitalization in the NICU and to identify factors associated with weaning failure, including corrected gestational age (CGA). This prospective, longitudinal, pragmatic and observational cohort study included neonates on mechanical ventilation for at least 48 h. The primary outcome was the accuracy of lung ultrasound in predicting 3-day weaning failure, with the ROC curve used to determine the best LUS cutoff (sensitivity and specificity).

Laboratório de Materiais Magnéticos Nanoestruturados (LaMMaN), Universidade Franciscana (UFN), Santa Maria, RS, Brazil.

The contamination of seas, rivers, lakes, and groundwater by industrial, hospital, and domestic effluents is a global health problem. Scientific approaches are needed to assess and mitigate the impacts of those pollutants, seeking more sustainable alternatives that meet established environmental standards. Among the various contaminants that are released into water sources, phenobarbital (PHEN), a long-acting barbiturate, applied as a hypnotic, sedative, and in the treatment of seizures is an aquatic pollutant, raises significant concerns for human health and the environment.

Article Synopsis
  • * The study compared these electrodes to traditional Ag/AgCl reference electrodes, finding that while Ag/AgCl showed greater charge transfer resistance, the carbon/graphene electrodes maintained comparable sensitivity and performance when lactate oxidase was used in the setup.
  • * Future investigations are necessary to address the reduction in electric current observed with human plasma, indicating potential issues with analyte detection sensitivity due to biological interferents.

Article Synopsis
  • The study evaluated the effectiveness of telemedicine, specifically nurse phone calls, in managing type 2 diabetes for patients transitioning to primary care after discharge from a tertiary clinic.
  • In a randomized clinical trial with 147 patients, there was no significant difference in HbA1c levels (a marker of blood sugar control) after 12 months between those who received telemedicine support and those who underwent standard care.
  • Overall, both groups maintained reasonable glycemic control, indicating that transitioning to primary care, with or without additional telemedicine support, was effective and safe for managing type 2 diabetes.
