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

BackgroundThe relationship between asthma and vitamin D deficiency has been known for some time. However, interventional studies conducted in this regard have shown conflicting results.ObjectiveTo evaluate the efficacy of vitamin D supplementation in asthmatic patients in improving the degree of control of asthma.MethodsRandomised, triple-blind, placebo-controlled, parallel-group study in adult asthmatic patients with serum 25-hydroxyvitamin-D3 <30 ng/mL. The intervention group received oral supplementation with 16 000 IU of calcifediol per week, and the control group had placebo added to their usual asthma treatment. The study period was 6 months. The primary endpoint was the degree of asthma control as determined by the asthma control test (ACT). Secondary endpoints included quality of life measured using the mini Asthma Quality of Life Questionnaire, the number of asthma attacks, oral corticosteroid cycles, the dose of inhaled corticosteroids, number of emergency visits, unscheduled consultations with the primary care physician and hospitalisations for asthma.ResultsOne hundred and twelve patients were randomised (mean age 55 years, with 87 (78%) being women). Of the 112 patients, 106 (95%) completed the trial. Half the patients (56) were assigned to the intervention group and the other half to the control group. A statistically significant clinical improvement was observed in the intervention group (+3.09) compared with the control group (−0.57) (difference 3.66 (95% CI 0.89 to 5.43); p<0.001) as measured using ACT scores. Among the secondary endpoints, a significant improvement in the quality of life was found in the intervention group (5.34), compared with the control group (4.64) (difference 0.7 (95% CI 0.15 to 1.25); p=0.01).ConclusionAmong adults with asthma and vitamin D deficiency, supplementation with weekly oral calcifediol compared with placebo improved asthma control over 6 months. Further research is needed to assess long-term efficacy and safety.Trial registration numberNCT02805907.

Background: Intermittent claudication (IC) is traditionally managed with risk factor modification, best medical treatment (BMT), and exercise training. Comorbidities such as diabetes and ischemic heart disease affect both results of invasive treatment and health-related quality of life (HRQoL) negatively. It is unknown how chronic widespread pain (CWP) influences the results of invasive treatment. We evaluated the influence of CWP on HRQoL in patients undergoing invasive (open surgery or endovascular treatment) and noninvasive BMT of IC. Methods: A total of 242 patients with IC treated with invasive or noninvasive methods responded to the validated HRQoL questionnaires Short Form 36 Health Survey, EuroQoL 5-dimensions, and distribution of pain with the Epipain questionnaire at baseline and after 12 months. Results: Invasively treated patients without CWP improved in all primary outcome measures. Patients with CWP reported significant improvements in most of the HRQoL-related outcome measures after invasive treatment, but patients with CWP in the noninvasive treatment group did not improve in any HRQoL-related outcome measure. Conclusions: The presence of CWP not should be a cause to withhold invasive treatment in patients with IC.
