AIM: Evaluation of secondary hyperparathyroidism (SHPT) and its prognostic impact on all-cause mortality in elderly males with heart failure (HF). METHODS: Seventy three males (67 ± 7 years old) with systolic HF were included. Baseline PTH was measured. Patients were grouped according to PTH cut-off levels of 65 pg/ml (>65 pg/ml = SHPT vs. normal PTH). All-cause mortality was evaluated at 6-year follow-up. RESULTS: SHPT was diagnosed in 43 (59 %) patients...

Neonatal chronic kidney disease (CKD) occurs with an estimated incidence of 1 in 10,000 live births, whereas the incidence of neonatal end-stage renal disease (ESRD) is about 7.1 per million age-related population. The most frequent etiologies are renal hypoplasia/dysplasia, posterior urethral valves, and other congenital anomalies of the kidney and urinary tract. Other etiologies include polycystic kidney disease, cortical necrosis, and renal vascular thrombosis. Management of CKD focuses primarily on replacing renal functions such as erythropoietin, 1,25-hydroxylation of vitamin D, electrolyte homeostasis/excretion, and, in ESRD, waste product removal...

BACKGROUND: Gastric diseases are a worldwide problem in modern society, as reported in the USA, in the range of 0.5-2 episodes/year/person and an incidence of 5-100 episodes/1000/week according to seasons and age. There is convincing evidence that oxidative stress is involved in the pathogenesis of acute gastric injury. Acid secreted from gastric parietal cells determines mucosal injuries which in turn cause inflammation and oxidative stress. Consequent inflammation produces free radicals by mitochondria thus causing lipid peroxidation, oxidative and acidic stress, which can lead to cell apoptosis...

The conversion of 7-dehydrocholesterol to cholesterol, the final step of cholesterol synthesis in the Kandutsch-Russell pathway, is catalyzed by the enzyme 7-dehydrocholesterol reductase (DHCR7). Homozygous or compound heterozygous mutations in DHCR7 lead to the developmental disease Smith-Lemli-Opitz syndrome, which can also result in fetal mortality, highlighting the importance of this enzyme in human development and survival. Besides serving as a substrate for DHCR7, 7-dehydrocholesterol is also a precursor of vitamin D via the action of ultraviolet light on the skin...

Huntington's disease is an autosomal dominant progressive neurodegenerative disease, which results in a decreased quality of life and an early death. A high prevalence of vitamin D deficiency was first described in a 2013 study in patients with manifest Huntington's disease, where serum vitamin D level was found to be associated with motor capabilities of the patients. Our objective was to investigate the effect of a high-dose vitamin D3 supplementation on a transgenic mouse model of Huntington's disease. Our study was performed on N171-82Q Huntington's disease transgenic mice in age- and gender-matched groups...

Currently, there have been few studies that have evaluated the incidence of vitamin D deficiency in adult burn patients or correlated vitamin D levels with burn-related outcomes. The primary objective of the study was to identify the incidence of vitamin D deficiency and insufficiency in an adult burn population. The secondary objective was to determine the impact of vitamin D deficiency and insufficiency on clinical outcomes in burn care. A single-center, retrospective, and observational cohort analysis of adult patients admitted for initial management of burn injury, who had a 25-hydroxyvitamin D (25D) level measured on admission, was performed...

In the last few decades a number of small, often largely unrecognized steps have fundamentally changed the management of systemic lupus erythematosus (SLE). The current goal is to stop all disease activity without long-term use of more than 5 mg prednisolone per day. Remission, i.e. absence of activity in the SLE activity score of choice, is the defined target in the treat to target approach. The essential basic measures include life-long hydroxychloroquine as well as protection from sunlight (UV) and vitamin D substitution...

Survival from melanoma is influenced by several, well-established clinical and histopathological factors, e.g. age, Breslow thickness and microscopic ulceration. We (the Section of Epidemiology and Biostatistics, University of Leeds) have carried out research to better understand the biological basis for these observations. Preliminary results indicated a protective role for vitamin D in melanoma relapse and that higher vitamin D was associated with thinner primary melanomas. Funding from the British Skin Foundation enabled JNB to establish a study of the effects of vitamin A in melanoma...

The aim of this study is to determine and critically evaluate the plausible relationships of vitamin D with extra-skeletal tissues in humans. Severe vitamin D deficiency results in rickets in children and osteomalacia in adults; these beneficial effects in the musculoskeletal system and certain physiological functions are well understood. Nevertheless, mounting reports support additional beneficial effects of vitamin D, outside the musculoskeletal system. This review explores the recent advances in knowledge about the non-skeletal effects of vitamin D...

We evaluated in the 7-year prospective study whether variants in vitamin D pathway genes and calcium-sensing receptor gene (CASR) are determinants of mortality in hemodialysis (HD) patients (n = 532). HRM analysis was used for GC rs2298849, GC rs1155563, RXRA rs10776909, RXRA rs10881578, and CASR rs7652589 genotyping. GC rs7041, RXRA rs749759, VDR rs2228570, and VDR rs1544410 were genotyped using PCR-RFLP analysis. The minor allele in GC rs2298849 was associated with all-cause mortality in univariate analysis (HR 1...

Over the last decades, several genetic disorders have been discovered in cattle. However, the genetic background of disorders in calves is less reported. Recently, German cattle farmers reported on calves from specific matings with chronic diarrhea and retarded growth of unknown etiology. Affected calves did not respond to any medical treatment and died within the first months of life. These calves were underdeveloped in weight and showed progressive and severe emaciation despite of normal feed intake. Hallmark findings of the blood biochemical analysis were pronounced hypocholesterolemia and deficiency of fat-soluble vitamins...

Previous studies with calves and other species have provided evidence that blood serum-derived proteins and fructooligosaccharides (FOS) may benefit intestinal health. We assessed the effects of supplementing products containing serum proteins as a component of arrival fluid support or serum proteins plus FOS (in addition to additional solids, minerals, and vitamins) in an early life dietary supplement on performance, morbidity, and mortality of stressed (transport, cold) male calves. Male Holstein calves (n = 93) <1 wk old were stratified by arrival body weight (BW) and plasma protein concentration, and then randomly assigned to 1 of 4 treatment groups in a 2 × 2 factorial arrangement of one-time administration of fluid support [either control electrolyte solution (E) or the serum protein-containing arrival formula (AF)] and 14 d of either no supplementation (NG) or supplementation with Gammulin (G; APC Inc...

Ipilimumab can induce long-term survival in 20% of patients with metastatic melanoma. Concurrent chronic medications may impact the patient's immune system, possess antimelanoma properties, and potentially affect clinical outcomes. This retrospective study sought to describe the efficacy and toxicity effects of 12 classes of chronic medications in metastatic melanoma patients treated with ipilimumab. A total of 159 adults who received ipilimumab for metastatic melanoma at Mayo Clinic (Rochester, Minnesota, USA) from 1 March 2011 through 31 December 2014 were included...
