RATIONALE, AIMS AND OBJECTIVES: The increasing number of diagnostic tests requests all over the world is a problem that can partially be explained by inappropriate testing. Impact on the total costs of health systems becomes relevant when tests are performed in a large amount. In this paper, retesting of total cholesterol, ferritin, vitamin B12 , vitamin D, and folate is assessed. METHODS: The Quality Unit of Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico di Milano (Fondazione) decided to perform a first assessment of the appropriate use of the laboratory tests cholesterol, ferritin, vitamin B12 , vitamin D, and folate focusing on the retesting interval for the same patient in the time period January 1, 2012, to December 31, 2014, in every care setting...

REVIEW
Harendran Elangovan, Sarinder Chahal, Jenny E Gunton
Consistent with its multifaceted nature, growing evidence links vitamin D with hepatic disease. In this review, we summarise the roles of vitamin D in different liver pathologies and explore the clinical utility of vitamin D-based treatments in hepatology. We find that the small number of clinical trials coupled with the profound heterogeneity of study protocols limits the strength of evidence needed to ascribe definite clinical value to the hormone in liver disease. Nevertheless, the experimental data is promising and further bench and bedside studies will likely define a clearer role in hepatic therapeutics...

Non-alcoholic fatty liver disease (NAFLD) is characterized by the accumulation of triglycerides, cholesterol and toxic free fatty acids and is related to low vitamin D levels. In an analysis of specific gene sets we elucidate to what extent NAFLD associates to epigenetic and related transcriptional changes in gene networks regulating lipid, energy and vitamin D balance. Two gene clusters responsible for lipid homeostasis (74 genes) and vitamin D and energy balance (31 genes) were investigated with regard to average epigenetic shifts within the first 1500bp next to the transcriptional start site...

PURPOSE: Some research findings suggest that calcium plus vitamin D (VitD) might have a preventive effect on nonalcoholic fatty liver disease development. Moreover, contradictory evidence also exists regarding calcium and VitD deficient diets. This study aimed to evaluate the effect of four different dietary calcium and VitD3 (cholecalciferol) levels on the development of high-fat, high-fructose (HFHFr) diet-induced nonalcoholic fatty liver disease and AMP-activated protein kinase (AMPK) phosphorylation...

Non alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease and liver enzymes abnormalities worldwide. NAFLD is reported to be associated with other extra-hepatic diseases including cardiovascular disease, diabetes mellites and thyroid gland abnormalities. Liver is also the source of many proteins involved in bone metabolism and is the regulator of several bone metabolism pathways. Although underlying pathogenesis is not clear, the association between NAFLD and low bone mineral density (BMD) in the forms of osteoporosis and osteopenia have been recently reported...

Many wildlife populations are declining at rates higher than can be explained by known threats to biodiversity. Recently, thiamine (vitamin B1) deficiency has emerged as a possible contributing cause. Here, thiamine status was systematically investigated in three animal classes: bivalves, ray-finned fishes, and birds. Thiamine diphosphate is required as a cofactor in at least five life-sustaining enzymes that are required for basic cellular metabolism. Analysis of different phosphorylated forms of thiamine, as well as of activities and amount of holoenzyme and apoenzyme forms of thiamine-dependent enzymes, revealed episodically occurring thiamine deficiency in all three animal classes...

In cattle, there are 2 significant forms of vitamin D: ergocalciferol (ERG) from fungi on roughage and cholecalciferol (CHO) from vitamin supplements or endogenous synthesis in the skin. The hypothesis of the present study is that vitamin D from the 3 sources is transported in different plasma fractions in the body. This is hypothesized to explain the lower efficiency of ERG compared to CHO in securing a sufficient plasma status of 25-hydroxyvitamin D and explain the inefficient excretion of dietary CHO into milk compared to endogenous CHO...

BACKGROUND: The Milan criteria are widely accepted for indicating liver transplantation in patients with hepatocellular carcinoma (HCC). However, a 7% to 20% possibility of HCC recurrence remains, even among patients who fulfill the Milan criteria. METHODS: We retrospectively reviewed 88 patients with HCC who underwent liver transplantation at Pusan National University Yangsan Hospital between May 2010 and December 2014. The risk factors for HCC recurrence were analyzed, and the overall survival and disease-free survival rates were calculated based on each risk factor...

Insulin-degrading enzyme (IDE, insulysin) is a rate-limiting enzyme in the insulin degradation process. It is an intracellular 110-kDa thiol zinc-metalloendopeptidase located in the cytosol, peroxisomes, endosomes and cell surface. IDE catalyzes degradation of several small proteins including insulin, amylin and β-amyloid protein. In addition, insulin clearance was expressed as a target in the treatment of type 2 diabetes given the role of hyperinsulinemia in the pathogenesis of insulin resistance. In this study, fourtyadult male Wistar albino rats were used, thirty rats received 20% fructose in drinking water (HFW) for six weeks to induce diabetes...

Traditional confinement practices limit exposure to sunlight and vitamin D synthesis, and vitamin insufficiency occurs even with dietary supplementation. The aim of this study was to determine the effect of limited sun exposure on serum concentration of vitamin D and the expression of vitamin D synthesizing enzymes in the liver and kidney of pigs on a vitamin D sufficient diet. White-pigmented grower pigs (29.7 ± 2.3 kg) fed 15% CP diet ad libitum providing >1,200 IU vitamin D3/kg of feed were exposed to sunlight for 1 h each day at solar noon for 14 d at the spring equinox (March pigs, n = 10) or summer solstice (June pigs, n = 5) and again before slaughter in June (March pigs) and September (June pigs)...

The association between vitamin D levels and nonalcoholic fatty liver disease (NAFLD) has been recognized. However, few studies showed independent associations between vitamin D deficiency and NAFLD after a sex-related adjustment for metabolic factors. We aimed to study whether vitamin D deficiency is an independent risk factor of NAFLD even after controlling for metabolic syndrome and visceral fat in both sexes. In this cross-sectional study, 7,514 Korean adults (5,278 men, 2,236 women) participated in a health check-up program...

Metabolic syndrome (MetS), characterized as obesity, insulin resistance, and non-alcoholic fatty liver diseases (NAFLD), is associated with vitamin D insufficiency/deficiency in epidemiological studies, while the underlying mechanism is poorly addressed. On the other hand, disorder of gut microbiota, namely dysbiosis, is known to cause MetS and NAFLD. It is also known that systemic inflammation blocks insulin signaling pathways, leading to insulin resistance and glucose intolerance, which are the driving force for hepatic steatosis...

Although aquatic organisms face multiple environmental stressors that may interact to alter adverse outcomes, our knowledge of stressor-stressor interaction on cellular function is limited. We investigated the combined effects of cadmium (Cd), hypoxia-reoxygenation (H-R) and temperature on mitochondrial function. Liver mitochondria from juvenile rainbow trout were exposed to Cd (0-20μM) and H-R (0 and 5min) at 5, 13 and 25°C followed by measurements of mitochondrial Cd load, volume, complex І active (A)↔deactive (D) transition, membrane potential, ROS release and ultrastructural changes...

The earliest record between sun exposure and skin disease goes back five millennia to the ancient Egyptians. The modern scientific era of medical light therapy and skin diseases started in 1877 when Downs and Blunt reported that exposure to light inhibited fungal growth in test tubes. Continuing research generated a growing medical interest in the potential the effects of light to treat and cure skin diseases considered as parasitic. This culminated in the awarding of the 1903 Nobel Prize in Medicine to Niels Finsen for his pioneering work showing that light could successfully treat cutaneous mycobacterium tuberculosis (lupus vulgaris), a disfiguring disorder common at the time...
