#1
Vlad Calin Radulescu
Venous thromboembolism (VTE) is very uncommon in children and adolescents compared with older adults, though its incidence has significantly increased over the past two decades. Given the rarity of the condition, the data on pediatric VTE lag behind the adult experience and consequently the management of VTE in children is, in large part, modeled on the adult strategies. This approach has certain limitations, given that young children have developmental particularities of the hemostatic system and differences in the pharmacokinetics and pharmacodynamics of various anticoagulant agents...

Direct oral anticoagulants (DOACs) exert similar anticoagulant effects to vitamin K antagonists and are increasingly used worldwide. Nevertheless, an evidence-based approach to patients receiving DOACs when any unplanned urgent surgery or bleeding (either spontaneous or traumatic) occurs is still missing. In this review, we investigate the role of point-of-care coagulation tests when other, more specific tests are not available. Indeed, thromboelastography and activated clotting time can detect dabigatran-induced coagulopathy, while their accuracy is limited for apixaban and rivaroxaban, mostly in cases of low drug plasma concentrations...

BACKGROUND: Metabolic syndrome (MetS) identifies subjects with increased risk of cardiovascular disease when they have a combination of insulin resistance, obesity, hypertension, hyperglycemia, low high-density lipoprotein cholesterol (HDL-C), and elevated triglycerides (TGs). Increasing evidence suggests that vitamin D deficiency could be associated with diabetes and MetS. The aim is to assess if 25-hydroxyvitamin D (25-OHD) is correlated with cardiovascular risk components of MetS. METHODS: A cross-sectional study involved 124 diabetic patients with MetS according to International Diabetes Federation definition...

Owing to its limited aqueous solubility, Phytomenadione (vitamin K) undergoes a low bioavailability (50%) with a large inter-individual variability after oral administration. Therefore, the aim of this work was to incorporate vitamine K into nanostructure lipid carrier systems to improve its aqueous solubility and bioavailability. Phytomenadione was used as a liquid lipid, Precirol ATO5, and Compritol ATO were used as solid lipids, Labrasol and Cremophore EL as water soluble surfactants, Capryol 90 and Lauroglycol as lipid soluble surfactants...

Injury to sensory afferents may contribute to the peripheral neuropathies that develop after administration of chemotherapeutic agents. Manipulations that increase levels of nicotinamide adenine dinucleotide (NAD) can protect against neuronal injury. This study examined whether nicotinamide riboside (NR), a third form of vitamin B3 and precursor of NAD, diminishes tactile hypersensitivity and place escape-avoidance behaviors in a rodent model of paclitaxel-induced peripheral neuropathy. Female Sprague-Dawley rats received 3 intravenous injections of 6...

Thiamin diphosphate (TPP, vitamin B1) is an essential coenzyme present in all organisms. Animals obtain TPP from their diets, but plants synthesize TPP de novo. We isolated and characterized an Arabidopsis pale green1 (pale1) mutant that contained higher concentrations of thiamin monophosphate (TMP) and less thiamin and TPP than the wild type. Supplementation with thiamin, but not the thiazole and pyrimidine precursors, rescued the mutant phenotype, indicating that the pale1 mutant is a thiamin-deficient mutant...

The vitamin D receptor is found on most cells, including active immune cells, implying that vitamin D has important biological functions beyond calcium metabolism and bone health. Although captive primates should be given a dietary source of vitamin D, under free-living conditions vitamin D is not a required nutrient, but rather is produced in skin when exposed to UV-B light. The circulating level of 25 hydroxyvitamin D (25-OH-D) considered adequate for humans is a topic of current controversy. Levels of circulating 25-OH-D sufficient for good health for macaques and other Old World anthropoids are assumed to be the same as human values, but data from free-living animals are scant...

BACKGROUND: Female athletes and active women require adequate nutrition for optimal health and performance. Nutrition assessments are needed to identify potential nutrients of concern. Folate, vitamin B6, and vitamin B12 function in important pathways used during physical activity and female athletes may be at risk for poor status of these micronutrients. This cross-sectional study described a comprehensive nutrition assessment of the B-vitamins (folate, vitamin B6, and vitamin B12) using both dietary (food and dietary supplements) and biochemical assessments among highly active and sedentary women...

REVIEW
Guillaume Jean, Jean Claude Souberbielle, Charles Chazot
Vitamin D deficiency (<20 ng/mL) and insufficiency (20-29 ng/mL) are common among patients with chronic kidney disease (CKD) or undergoing dialysis. In addition to nutritional and sunlight exposure deficits, factors that affect vitamin D deficiency include race, sex, age, obesity and impaired vitamin D synthesis and metabolism. Serum 1,25(OH)₂D levels also decrease progressively because of 25(OH)D deficiency, together with impaired availability of 25(OH)D by renal proximal tubular cells, high fibroblast growth factor (FGF)-23 and decreased functional renal tissue...

BACKGROUND: Early-life factors can be associated with future health outcomes and are often measured by maternal recall. METHODS: We used data from the North Carolina Early Pregnancy Study and Follow-up to characterize long-term maternal recall. We used data from the Early Pregnancy Study as the gold standard to evaluate the accuracy of pre-pregnancy weight, early pregnancy behaviors, symptoms and duration of pregnancy, and child's birthweight reported at follow-up, for 109 women whose study pregnancies had resulted in a live birth...

PURPOSE OF REVIEW: Nonalcoholic steatohepatitis (NASH), the aggressive form of nonalcoholic fatty liver disease (NAFLD), can progress to cirrhosis and hepatocellular cancer in 5-15% of patients and is rapidly becoming the leading cause for end-stage liver disease. Dietary caloric restriction and exercise, currently the cornerstone of therapy for NAFLD, can be difficult to achieve and maintain, underscoring the dire need for pharmacotherapy. This review presents the agents currently used in managing NAFLD and their pharmacologic targets...

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder of women of reproductive age characterized by polycystic ovarian morphology, anovulation or oligomenorrhea, and hyperandrogenism. It is shown that disruption in the steroidogenesis pathway caused by excess androgen in PCOS is a critical element of abnormal folliculogenesis and failure in dominant follicle selection. Vitamin D plays an important role in the regulation of ovulatory dysfunction and can influence genes involved in steroidogenesis in granulosa cells...

BACKGROUND AND OBJECTIVE: Vitamin D-1,25(OH)2 D3 or 1,25D3-maintains healthy osseous tissue, stimulates the production of the antimicrobial peptide cathelicidin and has anti-inflammatory effects, but it can cause hypercalcemia. Evidence links diminished serum levels of 1,25D3 with increased gingival inflammation. Periodontitis progression is associated with increased local production of inflammatory mediators by immune cells and gingival fibroblasts. These include interleukin (IL)-6, a regulator of osteoclastic bone resorption, and the neutrophil chemoattractant IL-8, both regulated by signaling pathways, including NF-κB and MAPK/AP-1...

Vitamin D has a range of non-skeletal health effects and has been implicated in the response to respiratory infections. The aim of this study was to assess the effect of vitamin D on the response of epithelial cells, neutrophils and macrophages to lipopolysaccharide (LPS) stimulation. BEAS-2B cells (airway epithelial cell line) and primary neutrophils and macrophages isolated from blood samples were cultured and exposed to LPS with and without vitamin D (1,25(OH)2D). The production of IL-6, IL-8, IL-1β and TNF-α of all cells and the phagocytic capacity of neutrophils and macrophages to E...

Vitamin D deficiency affects a large part of the population of elderly people, especially women, who live in moderate climate countries due to a reduced amount of vitamin D in the diet (small sea fish consumption) and reduced content of 7-dehydrocholesterol, which causes decreased skin synthesis. The lowest seasonal concentration of 25(OH)D3 is usually observed during winter and spring. Sun exposure influences 25(OH)D3 concentration more strongly in men than in women. Sociodemographic factors that increase the risk of vitamin D deficiency in the elderly include poor environmental conditions, low economic status, lower educational level, drug exposure (smoking), reduced physical activity, overall poor health and obesity, which causes reduced skin exposure to sunlight...

Serum uric acid (SUA), a causative agent for gout among others, is affected by both genetic and dietary factors, perhaps differentially by sex. We evaluated cross-sectional (SUAbase) and longitudinal (SUArate) associations of SUA with a genetic risk score (GRS), diet and sex. We then tested the interactive effect of GRS, diet and sex on SUA. Longitudinal data on 766 African-American urban adults participating in the Healthy Aging in Neighborhood of Diversity across the Lifespan study were used. In all, three GRS for SUA were created from known SUA-associated SNP (GRSbase (n 12 SNP), GRSrate (n 3 SNP) and GRStotal (n 15 SNP))...
