    The Strategy to Prevent and Regress the Vascular Calcification in Dialysis Patients.
    Biomed Res Int 2017 14;2017:9035193. Epub 2017 Feb 14.
    Division of Nephrology, Kaohsiung Veterans General Hospital, Kaohsiung, Taiwan; Department of Medicine, National Yang-Ming University School of Medicine, Taipei, Taiwan.
    The high prevalence of arterial calcification in end-stage renal disease (ESRD) is far beyond the explanation by common cardiovascular risk factors such as aging, diabetes, hypertension, and dyslipidemia. The finding relies on the fact that vascular and valvular calcifications are predictors of cardiovascular diseases and mortality in persons with chronic renal failure. In addition to traditional cardiovascular risk factors such as diabetes mellitus and blood pressure control, other ESRD-related risks such as phosphate retention, excess calcium, and prolonged dialysis time also contribute to the development of vascular calcification.

    Are Systematic Screening for Vitamin D Deficiency and Vitamin D Supplementation Currently Feasible for Ankylosing Spondylitis Patients?
    Int J Inflam 2017 1;2017:7840150. Epub 2017 Jan 1.
    Department of Medicine, Groote Schuur Hospital and University of Cape Town, Cape Town, South Africa.
    Beyond its role in calcium and phosphorus metabolism for healthy bone mineralization, there is increasing awareness for vitamin D contribution in modulation of immune reactions. Given that ankylosing spondylitis (AS) is a chronic inflammatory disease involving excess immune/inflammatory activity and posing great therapeutic challenges, it is conceivable to claim that vitamin D treatment may be a safe and effective treatment to influence or modify the primary disease and its related comorbidities. Nevertheless, consistent body of research supporting this hypothesis is still lacking. Read More

    J Korean Med Sci 2017 Jan;32(1):95-101
    Department of Family Medicine, Seoul National University Hospital, Seoul, Korea.
    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. Read More

    Gestational vitamin D deficiency and autism-related traits: the Generation R Study.
    Mol Psychiatry 2016 Nov 29. Epub 2016 Nov 29.
    Queensland Brain Institute, The University of Queensland, St Lucia, QLD, Australia.
    There is intense interest in identifying modifiable risk factors associated with autism-spectrum disorders (ASD). Autism-related traits, which can be assessed in a continuous fashion, share risk factors with ASD, and thus can serve as informative phenotypes in population-based cohort studies. Based on the growing body of research linking gestational vitamin D deficiency with altered brain development, this common exposure is a candidate modifiable risk factor for ASD and autism-related traits.

    Material And Methods: An observational prospective study in a tertiary children's University Hospital PICU conducted in two phases: i: cohorts study, and ii: prevalence study. The study included 340 critically ill children with ages comprising 6 months to 16 years old. Read More

    The Correlation Between Serum Vitamin D Deficiency and Preterm Birth.
    Med Sci Monit 2016 Nov 16;22:4401-4405. Epub 2016 Nov 16.
    Department of Nutrition and Food Hygiene, Guangdong Provincial Key Laboratory of Tropical Disease Research, School of Public Health, Southern Medical University, Guangzhou, Guangdong, China (mainland).
    BACKGROUND Preterm birth is an important cause of death and developmental disorder in neonates. Vitamin D deficiency has been shown to regulate body inflammatory factor levels that stimulate elevation of uterine contraction hormones, such as prostaglandin, thus causing preterm birth. However, current observations regarding the relationship between vitamin D and preterm birth are inconsistent. Read More

    Older Swedish Adults with High Self-Perceived Health Show Optimal 25-Hydroxyvitamin D Levels Whereas Vitamin D Status Is Low in Patients with High Disease Burden.
    Nutrients 2016 Nov 11;8(11). Epub 2016 Nov 11.
    Department of Medicine and Optometry, Linnaeus University, 392 34 Kalmar, Sweden.
    Controversy pervades the definition of adequate and optimal vitamin D status. The Institutes of Medicine have recommended serum 25(OH)D levels above 50 nmol/L based upon evidence related to bone health, but some experts, including the Endocrine Society and International Osteoporosis Foundation, suggest a minimum serum 25(OH)D level of 75 nmol/L to reduce the risk of falls and fractures in older adults. In a cross-sectional study, we compared vitamin D status in people ≥75 years selected from four groups with a frailty phenotype, combined with a control group free from serious illness, and who considered themselves completely healthy.

    Vitamin D3 Loading Is Superior to Conventional Supplementation After Weight Loss Surgery in Vitamin D-Deficient Morbidly Obese Patients: a Double-Blind Randomized Placebo-Controlled Trial.
    Obes Surg 2017 May;27(5):1196-1207
    Division of Endocrinology and Metabolism, Department of Internal Medicine III, Medical University of Vienna, Vienna, Austria.
    Background: Bariatric patients often suffer from vitamin D deficiency (VDD), and both, morbid obesity and VDD, are related to non-alcoholic fatty liver disease. However, limited data are available regarding best strategies for treating VDD, particularly, in bariatric patients undergoing omega-loop gastric bypass (OLGB). Therefore, we examined the efficacy and safety of a forced vitamin D dosing regimen and intervention effects in liver fibrotic patients. Read More

    Vitamin D (25(OH)D) in patients with chronic kidney disease stages 2-5.
    Colomb Med (Cali) 2016 Sep 30;47(3):160-166. Epub 2016 Sep 30.
    Universidad de Manizales, Manizales, Colombia.
    Objective: To establish the impact the chronic kidney disease stage has in the native vitamin D levels in patients not undergoing dialysis treatment.

    Methods: A study performed in Manizales, Colombia, a city located 2,200 meters above sea level, without important stational variations. Patients with 18 years of age or more, with chronic kidney disease stages 2 to 5 and not undergoing dialysis treatment were recruited for this study. Read More

    Decreased preoperative serum 25-Hydroxyvitamin D levels in colorectal cancer are associated with systemic inflammation and serrated morphology.
    Sci Rep 2016 Nov 7;6:36519. Epub 2016 Nov 7.
    Cancer and Translational Medicine Research Unit, University of Oulu, POB 5000, 90014 Oulu, Finland.
    Deficiency of vitamin D is associated with increased risk of several types of cancer including colorectal cancer (CRC). However, factors contributing to low levels of 25-hydroxyvitamin D [25(OH)D] in CRC are not clear. Therefore, in this study serum 25(OH)D levels in 117 CRC patients and 86 controls were analyzed and correlated with the clinicopathological data including morphological subtype (serrated or conventional), quantity of tumor infiltrating immune cells, levels of systemic inflammatory markers, and disease outcome.
