Vitamins are probably the best-selling dietary supplements in the United States, in which an estimated 35% of the population take multivitamin and mineral supplements. Data relating microconstituents to carcinogenesis are extremely limited, as explained in the first report. A striking feature of many of the compounds in the three groups mentioned above is their capacity to prevent or retard the occurrence of neoplasia. However, there is a paucity of data concerning the conditions under which inhibition occurs, the mechanisms of inhibition, and the precise impact of these microconstituents on humans. A literature review was conducted in the electronic databases PubMed and Google Scholar using the index terms "carcinogenesis" and "cancer" and "vitamin D" All types of studies were included for this study, such as randomized controlled trials, systematic reviews, literature reviews, and pilot studies published between 2010 and 2021. Articles which not written in English were excluded from the study. This search resulted in 10 papers. Many of the mechanisms proposed for vitamin D and cancer prevention have been studied only in the context of one tissue or one type of cancer and so further studies must be conducted to determine if these mechanisms can be generalized. For example, while higher serum (25(OH)D3) is associated with reduced cancer risk, and CYP27B1 is expressed in non-renal cells, there is no evidence that the low-level expression of CYP27B1 in tissues leads to meaningful local production of 1a,25(OH)2D3 or calcitriol, and that this mediates the protection from cancer provided by high vitamin D status. In conclusion, we suggest that vitamin D compounds to be employed in the treatment of, alone or in combination with other anticancer agents. solar UV-B radiation, acting through the production of vitamin D, is a risk reduction factor for over a dozen forms of cancer.

The authors present a stereotypical case presentation of X-linked hypophosphatemia (XLH) and provide a review of the pathophysiology and related pharmacology of this condition, primarily focusing on the FDA-approved medication burosumab. XLH is a renal phosphate wasting disorder caused by loss of function mutations in the PHEX gene (phosphate-regulating gene with homologies to endopeptidases on the X chromosome). Typical biochemical findings include elevated serum levels of bioactive/intact fibroblast growth factor 23 (FGF23) which lead to (i) low serum phosphate levels, (ii) increased fractional excretion of phosphate, and (iii) inappropriately low or normal 1,25-dihydroxyvitamin D (1,25-vitD). XLH is the most common form of heritable rickets and short stature in patients with XLH is due to chronic hypophosphatemia. Additionally, patients with XLH experience joint pain and osteoarthritis from skeletal deformities, fractures, enthesopathy, spinal stenosis, and hearing loss. Historically, treatment for XLH was limited to oral phosphate supplementation, active vitamin D supplementation, and surgical intervention for cases of severe bowed legs. In 2018, the United States Food and Drug Administration (FDA) approved burosumab for the treatment of XLH and this medication has demonstrated substantial benefit compared with conventional therapy. Burosumab binds circulating intact FGF23 and blocks its biological effects in target tissues, resulting in increased serum inorganic phosphate (Pi) concentrations and increased conversion of inactive vitamin D to active 1,25-vitD.

Background: Vitamin D has several roles, namely physiological function of calcium and bone metabolism, cell growth and differentiation, immune and cardiovascular function. Vitamin D deficiency can cause the risk of cancer. Head and neck cancer is one of the cancers that occur due to vitamin D deficiency in the body. This literature review was to asses and evaluate the impact and benefits of vitamin D supplementation for head and neck cancer.Discussion: A study found an association between vitamin D supplementation and a low risk of recurrence in conditions of high total vitamin D levels. Another study found a significant increase in quality of life (QOL). The primary mechanism of vitamin D action is mediated through binding of either 1,25(OH)2D3 (active form) or 25(OH)D (less active form) to the VDR, which is a member of the nuclear receptor superfamily of steroid and thyroid hormones with gene-regulatory and consequent anti-proliferative properties.Conclusions: Vitamin D supplementation provides a role in improving the condition of patients with head and neck cancer. Both in terms of suppressing recurrence and in terms of increasing quality of life

Women diagnosed with gestational diabetes mellitus (GDM) are more likely to later develop diabetes. Evidence from some previous reviews suggests that low vitamin D status during pregnancy increases the risk of developing GDM, but whether vitamin D during pregnancy also influences the risk of diabetes post GDM is less well studied. Thus, the aim of this systematic literature review was to summarize the current available literature on that topic. This review considered observational studies and randomized controlled trials (RCTs). Five databases were searched. The risk of bias of the included studies was assessed. A total of six studies were included: three observational studies and three RCTs. Findings were inconsistent across the six included studies. However, when considering RCTs only, the findings more strongly suggested that vitamin D supplementation during and after pregnancy did not have an influence on markers of diabetes development or diabetes development post GDM. This systematic review highlights inconsistent findings on the associations between vitamin D supplementation or concentration during and after pregnancy and markers of diabetes development or diabetes development post GDM; and although results from randomized interventional studies more strongly suggested no associations, the conclusion holds a high degree of uncertainty.

Abstract Objectives To assess existing evidence of the impact of vitamin D deficiency on reproductive success in infertile anovulatory females with polycystic ovary syndrome (PCOS) and evaluate the possible need for vitamin D supplementation. Methods A systematic literature review of published studies (2009–2019) on this topic was performed. One investigator independently reviewed primary research articles, extracted details, and determined the quality of each study. Results Of 64 peer-reviewed articles identified, 5 were reviewed, 5 were of plus/positive quality. Two studies assessed the prevalence of vitamin D deficiency in PCOS patients. One study assessed vitamin D administration effect on endometrial thickness, and two studies evaluated the effect of vitamin D status on ovulation and live birth rates after ovulation induction. Conclusions Vitamin D deficiency is prevalent in PCOS patients. Vitamin D status is an independent predictor of reproductive success in anovulatory patients with PCOS during ovulation induction. In such patients, vitamin D deficiency is associated with decreased ovulation and live birth rates, and vitamin D supplementation improves endometrial thickness. Based on the current data, further research is needed; meanwhile clinicians should monitor vitamin D status and recommend vitamin D supplementation to infertile anovulatory PCOS women with vitamin D deficiency.

The COVID-19 pandemic is having major economic and personal consequences for collegiate and professional sports. Sporting events have been canceled or postponed, and even when baseball and basketball seasons resumed in the United States recently, no fans were in attendance. As play resumed, several players developed COVID-19, disrupting some of the schedules. A hypothesis now under scientific consideration is that taking vitamin supplements to raise serum 25-hydroxyvitamin D [25(OH)D] concentrations could quickly reduce the risk and/or severity of COVID-19. Several mechanisms have been identified through which vitamin D could reduce the risks of infection and severity, death, and long-haul effects of COVID-19: (1) inducing production of cathelicidin and defensins to reduce the survival and replication of the SARS-CoV-2 virus; (2) reducing inflammation and the production of proinflammatory cytokines and risk of the “cytokine storm” that damages the epithelial layer of the lungs, heart, vascular system, and other organs; and (3) increasing production of angiotensin-converting enzyme 2, thus limiting the amount of angiotensin II available to the virus to cause damage. Clinical trials have confirmed that vitamin D supplementation reduces risk of acute respiratory tract infections, and approximately 30 observational studies have shown that incidence, severity, and death from COVID-19 are inversely correlated with serum 25(OH)D concentrations. Vitamin D supplementation is already familiar to many athletes and sports teams because it improves athletic performance and increases playing longevity. Thus, athletes should consider vitamin D supplementation to serve as an additional means by which to reduce risk of COVID-19 and its consequences.

For the past 15 years, cardiovascular disease (CVD) has been the leading cause of death for both men and women in the United States and worldwide. With an aging population, there has been increasing use of statin therapy to reduce the risk of CVD. However, statin-associated muscle symptoms (SAMS) remain an obstacle to this treatment, leading to discontinuation and nonadherence to statin therapy. Signs and symptoms of SAMS include muscle pain, tenderness, and increased serum creatine kinase. Despite the idiopathic pathophysiology of SAMS, some studies have shown an association between vitamin D deficiency and SAMS; the use of vitamin D supplements can lead to relief of these symptoms. The purpose of this review was to critique evidence for the association between low serum vitamin D and SAMS and the use of vitamin D supplementation for treatment.

Epidemiological evidence supports vitamin D deficiency as a risk factor for tuberculosis. Differences in solar ultraviolet B (UV-B) exposure, the major source of vitamin D, might therefore partially explain global variation in tuberculosis incidence.In a global country-based ecological study, we explored the correlation between vitamin D-proxies, such as solar UV-B exposure, and other relevant variables with tuberculosis incidence, averaged over the period 2004–2013.Across 154 countries, annual solar UV-B exposure was associated with tuberculosis incidence. Tuberculosis incidence in countries in the highest quartile of UV-B exposure was 78% (95% CI 57–88%, p<0.001) lower than that in countries in the lowest quartile, taking into account other vitamin D-proxies and covariates. Of the explained global variation in tuberculosis incidence, 6.3% could be attributed to variations in annual UV-B exposure. Exposure to UV-B had a similar, but weaker association with tuberculosis notification rates in the multilevel analysis with sub-national level data for large countries (highestversuslowest quartile 29% lower incidence; p=0.057).The potential preventive applications of vitamin D supplementation in high-risk groups for tuberculosis merits further investigation.
