Objective: Anti-Müllerian Hormone (AMH) concentration is high at birth in males, demonstrating the presence of functional testicular tissue in the prepubertal period, and acting as a useful marker in the investigation of paediatric reproductive disorders. AMH also provides a tool in the investigation of female virilization, premature ovarian failure and polycystic ovarian syndrome in childhood. Robust, assay-specific paediatric AMH reference intervals are therefore required for clinical interpretation of results. The aim of this study was to derive age-specific AMH reference intervals for males and females aged 0-18 years.
Design And Patients: Plasma samples were obtained from patients at Royal Manchester Children's Hospital and analysed for AMH using the automated Beckman Coulter Access AMH Assay. Patients under investigation for paediatric reproductive or endocrine disorders were excluded from the study.
Measurements: Seven hundred and 2 patient plasma samples (465 male, 237 female) were subject to AMH measurement, and results were analysed in order to derive continuous and discrete reference intervals for the paediatric age range.
Results: Clear discrimination between male and female AMH results was evident in the prepubertal age range, with some overlap between the genders following pubertal onset.
Conclusions: We have derived age-related reference intervals for plasma AMH in the paediatric age range (0-18 years) using the automated Beckman Coulter Access AMH assay which will aid in the investigation of paediatric endocrine disorders such as disorders of sexual development.

Department of Obstetrics and Gynecology, Tohoku University Graduate School of Medicine, Sendai, Miyagi, Japan.
Aims: This study investigated the association between maternal age and early and late gestational diabetes mellitus (GDM).
Methods: In total, 72,270 pregnant women were included in this prospective birth cohort study. Associations between maternal age and early GDM (diagnosed at <24 gestational weeks) and late GDM (diagnosed at ≥24 gestational weeks) were evaluated using a multinomial logistic regression model with possible confounding factors.
Vitamin D Supplementation in Critically Ill-Narrative Review.

Department of Anesthesiology, Reanimatology and Intensive Care, University Hospital Split, 21000 Split, Croatia.
Background: Studies have shown a high prevalence of vitamin D deficiency in critically ill patients, and these patients are at higher risk for pneumonia and have increased incidence of sepsis and mortality. In this study, we reviewed available literature from randomized controlled trials (RCTs) on vitamin D supplementation in critically ill patients and summarized the evidence in this narrative review.
Methods: Randomized controlled trials that included vitamin D supplementation as an intervention were eligible for inclusion.
The Influence of Rice Types and Boiling Time on Glycemic Index: An In Vivo Evaluation Using the ISO 2010 Method.

Effective blood glucose management is essential for individuals with type 1 diabetes, particularly when dietary adjustments involve staple foods like rice. As a primary carbohydrate worldwide, rice significantly influences the glycemic index (GI) based on its type and cooking method. This study investigated the impact of rice type and boiling duration on the GI in healthy adults using an in vivo approach aligned with ISO 2010 standards.

: The current gold standards for diagnosing acute kidney injury (AKI) are an increase in serum creatinine and a decrease in urine output, which are inadequate for rapid diagnosis. Neutrophil gelatinase-associated lipocalin (NGAL) is a 25-kDa protein produced and secreted by injured kidney tubule epithelial cells, and can serve as an early urinary biomarker for AKI. ProNephro AKI (NGAL) is an immunoassay for the quantitative determination of NGAL in urine (uNGAL) that recently received FDA clearance.

Several studies have highlighted the essential role of taurine in maintaining the health of small animals, particularly dogs. Taurine deficiency has been linked to various health issues, especially in certain dog breeds. Therefore, accurately assessing taurine levels in canine blood is crucial for diagnosing and monitoring these conditions.
