Effects of vitamin D supplementation on serum lipid profile in women with polycystic ovary syndrome: A protocol for a systematic review and meta-analysis.

Medicine (Baltimore) 2020 Jun;99(23):e20621

Hospital of Chengdu University of Traditional Chinese Medicine, Chengdu, Sichuan Province, P.R. China.

Background: Polycystic ovary syndrome (PCOS) is the commonest endocrine disorder in reproductive-aged women. In addition to the reproductive consequences, PCOS is also characterized by a metabolic disorder, which may play a part in the etiology of anovulation and has important implications for long-term health as well. Vitamin D deficiency is prevalent in PCOS and there is a close relationship between metabolic dysfunction and vitamin D status in women with PCOS. Read More

Does Vitamin D play a role in the management of Covid-19 in Brazil?

Rev Saude Publica 2020 1;54:53. Epub 2020 Jun 1.

Faculty of Health and Medical Sciences, School of Biosciences and Medicine, University of Surrey, Guildford, Surrey, United Kingdom.

The study discusses the possible role of adequate vitamin D status in plasma or serum for preventing acute respiratory infections during the Covid-19 pandemic. Our arguments respond to an article, published in Italy, that describes the high prevalence of hypovitaminosis D in older Italian women and raises the possible preventive and therapeutic role of optimal vitamin D levels. Based on literature review, we highlight the findings regarding the protective role of vitamin D for infectious diseases of the respiratory system. Read More

Subacute combined degeneration induced by nitrous oxide inhalation: Two case reports.

Medicine (Baltimore) 2020 May;99(18):e19926

Department of Neurology, The Affiliated Hospital of Qingdao University, 16 Jiangsu Road, Qingdao, Shandong Province.

Rationale: Nitrous oxide (N2O), commonly known as "laughing gas," is being increasingly abused by young people as a recreational drug; this can subsequently result in myelopathy and peripheral neuropathy, however, in China, few cases of neurologic deterioration by N2O abuse have been reported.

Patient Concerns: Herein, we present 2 patients who developed progressive limb weakness, numbness, and ataxia. Both of them had recreationally inhaled N2O intermittently for a long time. Read More

Sex-Specific SARS-CoV-2 Mortality: Among Hormone-Modulated ACE2 Expression, Risk of Venous Thromboembolism and Hypovitaminosis D.

Int J Mol Sci 2020 Apr 22;21(8). Epub 2020 Apr 22.

Department of Clinical and Experimental Medicine, University of Catania, 95123 Catania, Italy.

Severe acute respiratory syndrome coronavirus (SARS-CoV-2) disease (COVID-19) appears to have a higher mortality rate in presence of comorbidities and in men. The latter suggests the presence of a possible sex-dependent susceptibility. An enzymatic system involved in this different predisposition could be represented by angiotensin converting enzyme 2 (ACE2). Read More

Department of Pediatric Dentistry, The University of Texas Health Science Center at Houston, School of Dentistry, Houston, Texas, USA.

Background: Scurvy, the disease resulting from vitamin C deficiency, is perceived as being rare and occurring predominantly in the past. However, scurvy continues to exist and may be encountered in children with medical/developmental conditions and/or restricted diet. Diagnosis can be challenging given the perceived rarity of the condition and nonspecific symptoms, including gingival disease. Read More

Subcell Biochem 2020 ;95:27-55

Department of Food Science, Rutgers Center for Lipid Research, New Jersey Institute for Food, Nutrition, and Health, Rutgers University, New Brunswick, NJ, 08901, USA.

The placenta, a hallmark of mammalian embryogenesis, allows nutrients to be exchanged between the mother and the fetus. Vitamin A (VA), an essential nutrient, cannot be synthesized by the embryo, and must be acquired from the maternal circulation through the placenta. Our understanding of how this transfer is accomplished is still in its infancy. Read More

Maine Medical Center Research Institute, 81 Research Drive, Scarborough, Maine, 04074, USA.

Vitamin A deficiency studies have been carried out since the early 1900s. Initially, these studies led to the identification of fat soluble A as a unique and essential component of the diet of rodents, birds, and humans. Continuing work established that vitamin A deficiency produces biochemical and physiological dysfunction in almost every vertebrate organ system from conception to death. Read More

Background: To determine the prevalence of subacute combined degeneration (SCD) patients with normal or elevated serum vitamin B12 level and to identify clinical characteristics of these patients.

Methods: We searched PubMed, EMBASE, and Cochrane library, without language restriction up to June 2019 and included studies with SCD patients who were diagnosed with normal or elevated serum vitamin B12 levels. Meta-analysis was performed to estimate the prevalence of SCD in patients with normal or elevated serum vitamin B12 levels and compare the differences of clinical data between patients with low and no-low serum vitamin B12 level.

Genetic predisposition for vitamin D deficiency is not associated with adverse outcome of very low birth weight infants: A cohort study from the German Neonatal Network.

PLoS One 2020 31;15(3):e0230426. Epub 2020 Mar 31.

Department of Pediatrics, University of Lübeck, Lübeck, Germany.

Objective: Postnatal vitamin D supplementation is standard of care in neonates and preterm infants. Despite routine supplementation of vitamin D, a wide range of complications related to vitamin D deficiency has been described in the literature. Since standard vitamin D supplementation might be not sufficient in preterm infants with a genetic predisposition for vitamin D deficiency, we investigated the outcome of preterm infants with regard to their genetic estimated vitamin D levels.

Low serum 25-hydroxyvitamin D status in the pathogenesis of stress fractures in military personnel: An evidenced link to support injury risk management.

PLoS One 2020 24;15(3):e0229638. Epub 2020 Mar 24.

Institute of Naval Medicine, Alverstoke, Hampshire, United Kingdom.

Stress fractures are common amongst healthy military recruits and athletes. Reduced vitamin D availability, measured by serum 25-hydroxyvitamin D (25OHD) status, has been associated with stress fracture risk during the 32-week Royal Marines (RM) training programme. A gene-environment interaction study was undertaken to explore this relationship to inform specific injury risk mitigation strategies. Read More

N-acetylcysteine (NAC), an anti-oxidant, does not improve bone mechanical properties in a rat model of progressive chronic kidney disease-mineral bone disorder.

PLoS One 2020 23;15(3):e0230379. Epub 2020 Mar 23.

Department of Anatomy, Cell Biology and Physiology, Indiana University School of Medicine, Indianapolis, IN, United States of America.

Individuals with chronic kidney disease have elevated levels of oxidative stress and are at a significantly higher risk of skeletal fracture. Advanced glycation end products (AGEs), which accumulate in bone and compromise mechanical properties, are known to be driven in part by oxidative stress. The goal of this study was to study effects of N-acetylcysteine (NAC) on reducing oxidative stress and improving various bone parameters, most specifically mechanical properties, in an animal model of progressive CKD.

Qinghai University Affiliated Hospital, Xining, Qinghai Province.

Background: The findings on the association between elevated plasma homocysteine levels and the risk of the trial of org 10172 in acute stroke treatment (TOAST) of ischemic stroke have been inconsistent in Chinese. So far, there is no meta-analysis about the association between Hcy and the TOAST subtypes of ischemic stroke in Chinese.
