Background: Benedict's test for the screening of galactosemia presents a high false-positive rate, which puts into question its usefulness.
Methods: We evaluated the results of Benedict's test as screening strategy for galactosemia, and the patients' definite diagnosis in our hospital in the last 25 years. We also assessed the most prevalent clinical conditions among the false-positive cases.
Results: Apart from glycosuria, many non-galactosemic newborns with heart alterations, prematurity, icterus and sepsis usually lead to false-positive results using Benedict's. No false-negative case for Benedict's test was reported in our hospital.
Conclusions: A better approach in terms of cost-effectiveness, sensitivity and specificity is needed for an effective screening of galactosemia.

Evaluating the effects of continuous veno-venous hemodiafiltration on O and CO removal and energy expenditure measurement using indirect calorimetry.
Ann Intensive Care

Department of Intensive Care Medicine, Universitaire Ziekenhuis Brussel (UZ Brussel), Vrije Universiteit Brussel (VUB), Brussels, Belgium.
Background: Continuous veno-venous hemodiafiltration (CVVHDF) is used in critically ill patients, but its impact on O₂ and CO₂ removal, as well as the accuracy of resting energy expenditure (REE) measurement using indirect calorimetry (IC) remains unclear. This study aims to evaluate the effects of CVVHDF on O₂ and CO₂ removal and the accuracy of REE measurement using IC in patients undergoing continuous renal replacement therapy.
Design: Prospective, observational, single-center study.
Battlefield Acupuncture Does Not Provide Additional Improvement in Pain When Combined With Standard Physical Therapy After Shoulder Surgery: A Randomized Clinical Trial.

Introduction: Shoulder stabilization surgery is common among military personnel, causing severe acute postoperative pain that may contribute to the development of chronic pain, thereby reducing military readiness. Battlefield Acupuncture (BFA) has shown promise as a non-pharmaceutical intervention for acute postoperative pain. The purpose of this study was to determine the effectiveness of BFA combined with standard physical therapy on pain, self-reported mood, self-reported improvement, and medication use in patients after shoulder stabilization surgery.

Purpose: This study's purpose was to investigate whether self-efficacy is a risk factor for musculoskeletal injury in an initial military training environment and compare it to other known risk factors.
Association of Demographic Disparities in Maternal Oral Hygiene Status, Caries Experience, and Oral Health Behavior Toward Children in Chengalpattu District, India: A Cross-Sectional Study.

Department of Public Health Dentistry, Chettinad Dental College and Research Institute, Chennai, IND.
Background And Objective: Mothers are the primary caregivers throughout early childhood, playing a vital role in developing their child's oral health behavior, as oral conditions in primary teeth can have a considerable negative impact on the child's growth. This study aims to assess the association between maternal oral hygiene status, caries experience, and oral health behavior (OHB) toward their children.
Methodology: A cross-sectional study was conducted among 226 mothers of children aged nine months to three years visiting the primary health centers (PHCs) in urban (n = 113) and rural (n = 113) areas of Chengalpattu district, India.
PD-1 and CD73 on naive CD4 T cells synergistically limit responses to self.

Vaccination with self- and foreign peptides induces weak and strong expansion of antigen-specific CD4 T cells, respectively, but the mechanism is not known. In the present study, we used computational analysis of the entire mouse major histocompatibility complex class II peptidome to test how much of the naive CD4 T cell repertoire specific for self-antigens was shaped by negative selection in the thymus and found that negative selection only partially explained the difference between responses to self and foreign. In naive uninfected and unimmunized mice, we identified higher expression of programmed cell death protein 1 (PD-1) and CD73 mRNA and protein on self-specific CD4 T cells compared with foreign-specific CD4 T cells.
