Purpose: Children with epilepsy (CWE) are at risk of vitamin D deficiency. Single nucleotide polymorphisms (SNPs) affecting the vitamin D pathway are potentially important risk factors for serum 25-hydroxyvitamin D [25(OH)D] concentration. The aims of our study were to evaluate the association of vitamin d-related SNPs to serum 25(OH)D concentrations in Malaysian CWE.
Methods: Cross-sectional study of Malaysian ambulant CWE on antiseizure medication for >1 year. Sixteen SNPs in 8 genes (GC, VDR, CYP2R1, CYP24A1, CYP27B1, CYP27A1, CYP3A4, NADSYN1/DHCR7) were genotyped. Linear and logistic regression models and co-variates adjusted analyses were used. SNPs with significant associations were further analysed in a group of ethnically-matched healthy Malaysian children.
Results: 239 CWE were recruited (52.7% Malay, 24.3% Chinese and 23.0% Indian) with mean serum 25(OH)D of 58.8 nmol/L (SD 25.7). Prevalence of vitamin D deficiency (≤37.5 nmol/L) was 23.0%. Minor allele of GC-rs4588-A was associated with lower serum 25(OH)D in the meta-analysis of both CWE (β -8.11, P = 0.002) and Malaysian healthy children (β -5.08, P < 0.001), while VDR-rs7975232-A was significantly associated with reduced odds of vitamin D deficiency in Malay subgroup of CWE (OR: 0.16; 95% CI: 0.06-0.49; P = 0.001) and this association was not found in the healthy children group.
Conclusions: Our results suggest that GC-rs4588 is associated with lower serum 25(OH)D concentration in both Malaysian CWE and healthy children, while VDR-rs7975232A is associated with lower risk of vitamin D deficiency in Malaysian CWE of Malay ethnicity. Our findings may assist in the genetic risk stratification of low vitamin D status among CWE.

The diagnosis of hemolysis is still based on straightforward biochemical parameters: haptoglobin (the most sensitive), lactate dehydrogenase (LDH), and unconjugated bilirubin. Anemia is not always present. Reticulocyte counts typically exceed 120×10/L, except in cases of associated vitamin deficiency or during the very early phase of acute hemolysis.

Symptoms of bleeding caused by vitamin K-dependent coagulation factor deficiency (VKCFD) are rare in adults. We present two Japanese cases of adult-onset VKCFD, in which the cause of vitamin K deficiency remains unknown despite comprehensive evaluation. Both patients showed markedly decreased levels of coagulation factors (F) VII, FIX, FX, FII, protein C (PC), and protein S (PS), along with elevated levels of protein induced by vitamin K absence/antagonist II (PIVKA-II).

Fatal infections with the rare COUG strain of the zoonotic parasite Toxoplasma gondii were recently detected for the first time in four southern sea otters (Enhydra lutris nereis) exhibiting severe protozoal steatitis. The objectives of this study were to describe new COUG strain infections in sea otters, investigate the potential contributory role of a recently discovered parasite-infecting narnavirus (Apocryptovirus odysseus) in these infections, assess the potential contribution of vitamin E deficiency in the development of systemic steatitis, and explore the utility of serotyping for strain-specific diagnosis of T. gondii infections in sea otters.

Background: Sunscreen reduces vitamin D production in experimental studies. It is uncertain whether this translates to 'real-world' settings.
Objectives: We aimed to dtermine if routinely applying high-SPF sunscreen for one year reduces serum 25-hydroxyvitamin D [25(OH)D] concentration.
