Vitamin D Roles Across Developmental Stages in Pediatric Pneumonia: Linking Genetics, Microbiome, Maternal Status and Immunity

Health Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background Pneumonia remains a leading cause of morbidity and mortality among children globally, especially in low‐ and middle‐income countries, where poor nutrition and limited access to healthcare increase vulnerability. Vitamin D deficiency is common among children and has emerged as a significant risk factor associated with respiratory ...

Delayed diagnosis of 3β‐HSD7 deficiency in adolescence: Two case reports and review of the literature

JPGN Reports, Volume 7, Issue 2, Page 236-241, May 2026.
Abstract Congenital bile acid synthesis defects (BASD), the most common of which is 3β‐hydroxy‐Δ5‐C27‐steroid dehydrogenase oxidoreductase (3β‐HSD7) deficiency, are a rare cause of fat‐soluble vitamin malabsorption. We describe a 14‐year‐old girl who presented at 14 months with a left distal femur fracture and failure to thrive.

Unusual presentation of vitamin D-dependent rickets type II in a kitten

Journal of Feline Medicine and Surgery Open Reports, 2020
Case summary A 15-week-old kitten presented with a 1-month history of intermittent generalised tremors and abdominal distension. Hypocalcaemia associated with increased 1,25-vitamin D 3 was consistent with vitamin D 3 -dependent rickets type II. The bone

Carrier screening in the reproductive setting—Are there medical implications for the heterozygote?—A guide for clinicians

Pregnancy, Volume 2, Issue 3, May 2026.
Abstract Carrier screening for genetic conditions performed preconception or during pregnancy allows identification of fetal risk for inherited autosomal recessive and X‐linked conditions. The goal is to identify at‐risk patients/couples and offer them reproductive options such as preimplantation genetic diagnosis, prenatal testing, or targeted newborn

Synergistic Tuning of Conformational Dynamics, Electron Tunneling, and Substrate Positioning Enhances Electron Transfer in a P450 Chimera for Calcifediol Biosynthesis

Advanced Science, Volume 13, Issue 22, 17 April 2026.
A synergistic electron transfer (ET) optimization strategy modulating conformational dynamics, ET pathway, and substrate orientation is proposed for self‐sufficient cytochrome P450s. Guided by this strategy, a P450 variant with improved ET and catalytic efficiency was identified, and the underlying molecular basis was revealed by computational analysis.

Cortical Bone Loss in Barcelona Across Time (1st Century CE–18th Century CE) and Its Potential Relationship With Linear Enamel Hypoplasia

American Journal of Biological Anthropology, Volume 189, Issue 4, April 2026.
ABSTRACT Objectives The purpose of this study is to conduct a diachronic analysis of cortical bone loss in Barcelona, spanning from the 1st to 18th century CE, assessing the relationship between cortical bone loss and early‐life stressors, as indicated by linear enamel hypoplasia (LEH) across Roman, Late Antiquity, Medieval, and Modern periods and ...
