Objective: To limit the regulation of antibiotherapy in neonatal early infections by improving the tracking and the diagnosis of infected newborns.
Patients And Method: First part: analysis of procalcitonin (PCT) in the cord. Method of tracking: 87 cases. Cut-off PCT=0.5 ng/mL. Measurement of CRP at 24 h if PCT>0.5 ng/mL. Second part: analysis of the PCT between 4 h and 6 h in the event of infectious risk; 47 cases over 6 months. Cut-off PCT=2 ng/mL. Measurement of CRP at 12 h and/or 24 h.
Results: In 2012, there were 10 antibiotherapies prescribed per 1000 births versus 30/1000 in 2011. A reduction in two thirds of the indications was seen.
Conclusion: Markers of inflammation, i.e., the PCT (good specificity and good negative predictive value from 0 to 6 h of life) and CRP (good sensitivity and good positive predictive value from 12 to 24 of life) should be combined in time.

Vitamin D status and its determinants in German elite athletes.
Eur J Appl Physiol
January 2025
Department of Exercise Physiology and Sports Therapy, Institute of Sports Science, Justus Liebig University Giessen, Kugelberg 62, 35394, Giessen, Germany.
Purpose: This study investigated elite German athletes to (1) assess their serum 25(OH)D levels and the prevalence of insufficiency, (2) identify key factors influencing serum 25(OH)D levels, and (3) analyze the association between serum 25(OH)D levels and handgrip strength.
Methods: In this cross-sectional study, a total of 474 athletes (231 female), aged 13-39 years (mean 19.3 years), from ten Olympic disciplines were included.

This study aimed to identify the correlation of serum 25(OH)D level with sarcopenia and its components in Chinese elderly aged 65 years and above from rural areas. A total of 368 Chinese elderly aged 65 years and above in rural areas were enrolled. Indicators of muscle mass and strength, including the appendicular skeletal muscle mass (ASM), skeletal muscle index (SMI) and hand grip strength (HGS) were measured.

Objective: This investigation aimed to compare MMP-9 levels and ocular surface parameters in diabetic patients with and without DED.
Synthesis of GO-SiO/ZnO/FeO nano adsorbent for preconcentration of aflatoxins in food samples using SPE-HPLC-FLD method.
Food Chem
December 2024
Department of Food Safety and Quality Control, Research Institute of Food Science and Technology (RIFST), Mashhad, Iran.
This study demonstrates a new extraction method for determination of aflatoxins (AFs) in food samples by a GO-SiO/ZnO/FeO nanocomposite as new and effective sorbent. The nanocomposite structure was confirmed by FT-IR, XRD, EDX, FE-SEM, TEM, and mapping techniques. Optimization of the extraction process was conducted by investigating pH, adsorbent amount, sample volume, and solvent volume using central composite design (CCD).

Division of Clinical Pharmacology, Department of Medicine, University of Cape Town, Cape Town, South Africa. Electronic address:
A robust LC-MS/MS method was developed to quantify total and unbound doravirine in plasma samples from patients receiving daily doses of 100 mg doravirine, in combination with lamivudine and tenofovir disoproxil fumarate, in a phase 3 clinical trial. The trial is ongoing, and sample analysis is planned to commence once all samples have been collected. The method was validated to quantify both total and unbound doravirine using a single calibration curve.
