Summary: Laboratory evidence supports the benefits of vitamin D in COVID-19, with supplementation linked to reduced respiratory infection risk. Most clinical studies are observational, with a key limitation being confounding factors. While observational studies show potential benefits, randomized controlled trials are needed to confirm the effectiveness of vitamin D supplementation in COVID-19 patients.

Summary: This study investigates the association between vitamin D deficiency and COVID-19 severity among survivors. The findings show a correlation between vitamin D deficiency and severe cases, as well as the presence of post-acute sequelae of COVID-19 (PASC) among survivors. Gender and BMI are also found to be related to vitamin D levels, but not to the presence of PASC.

Summary: This study compared serum 25-hydroxyvitamin D (25(OH)D) levels in patients with Cushing's disease (CD) and controls, finding that CD patients had lower levels of vitamin D and that 25(OH)D levels were negatively correlated with urinary free cortisol. Cholecalciferol supplementation had a positive impact on insulin sensitivity and lipids.

Summary: The study found that cooking significantly increased the concentration of vitamin D in pork, with different cooking methods having minimal impact on the retention of vitamin D. Interestingly, the type of pork product had a greater influence on the concentration of vitamin D than the cooking method.

Summary: This study aimed to estimate the vitamin D status of participants residing in Malaysia. The results showed that despite being close to the equator, more than half of Malaysians have insufficient vitamin D levels. Higher proportions of vitamin D insufficiency were found in participants living in urban areas, females, and Malays and Malaysian Indians ethnicities.

Summary: There is a strong positive linear correlation between free 25(OH)D (f25(OH)D) and total 25(OH)D, making them useful for assessing vitamin D levels. The recommended threshold level for f25(OH)D is 8.499 pg/mL, corresponding to a target concentration of at least 30 ng/mL for t25(OH)D. The upper limit for vitamin D is still unclear, with most experts favoring a upper limit of 100 ng/mL for t25(OH)D.

Summary: The results of two studies suggest that vitamin D sufficiency can reduce the risk of upper respiratory tract infections during military training. Vitamin D supplementation strategies have similar effects in increasing vitamin D levels, significantly reducing the severity of respiratory infection symptoms and days with colds.

Summary: This study used a bidirectional two-sample Mendelian randomization (MR) design to investigate the causal association between polycystic ovary syndrome (PCOS) and 25-hydroxyvitamin D (25OHD) deficiency. The findings showed a negative association between genetically determined PCOS and 25OHD levels, but this causal effect disappeared when adjusting for obesity and insulin resistance. The study failed to find a substantial causal effect of 25OHD deficiency on the risk of PCOS. Further observational studies and clinical trials are needed.

Summary: This study confirms an inverse dose-dependent association between serum 25-hydroxyvitamin D levels and elevated intraocular pressure (EIOP) in a large sample of 15,338 individuals. Each unit increase in serum 25-hydroxyvitamin D is associated with a 3% decrease in the odds of having EIOP. Compared to individuals deficient in 25-hydroxyvitamin D, those with insufficiency and sufficiency have a 28% and 49% lower odds of EIOP, respectively. Therefore, clinical assessment of intraocular pressure may be helpful in the treatment and prevention of glaucoma in patients with insufficient 25-hydroxyvitamin D.

Summary: This study aimed to evaluate the association between dietary vitamin D intake and serum vitamin D concentrations with cognitive performance in older Americans. The results showed a positive association between dietary vitamin D intake, serum total 25-hydroxyvitamin D, and cognitive performance, with no significant gender differences in the associations. Further research is needed to clarify the effects of dietary vitamin D intake and specific serum D concentrations on cognitive performance.

Summary: This study evaluated the association between 25(OH)D (total, free, and bioavailable) with adiposity and metabolic traits. The findings suggest that free and bioavailable 25(OH)D do not offer additional advantages over total 25(OH)D regarding its association with adiposity and several metabolic traits in Mexican adults.

Summary: This study aimed to assess the effect of vitamin D supplementation at different doses on serum 25(OH)D concentrations in preschool children. After three months, there was a significant increase in serum concentrations of 25(OH)D and a decrease in the prevalence of vitamin D deficiency. No adverse effects were observed.

Summary: This post hoc analysis investigated the effects of vitamin D on blood pressure and found that vitamin D supplementation did not have an antihypertensive effect in individuals with vitamin D deficiency. However, there was a significant association between achieved 25(OH)D concentrations and blood pressure.

Summary: This study assessed the prevalence of 25(OH)D deficiency in UK-dwelling South Asians and found a significant proportion of the population had varying degrees of vitamin D deficiency. Important predictors of deficiency included gender, ethnicity, BMI, age, dietary habits, and seasonal factors.

Summary: The traditional approaches to measuring depression after traumatic brain injury (TBI) have limitations. This study adopted a symptom-oriented approach and found that post-TBI depression is highly heterogeneous. Different depressive symptoms have distinct associations with personal, injury-related, treatment, and outcome factors.

Summary: Despite rapid social changes in Hong Kong, marriage remains a strong protective factor against suicide for both men and women, particularly among younger individuals. Increasing suicide rates among divorced/separated, never-married, or widowed individuals suggest a need for more psychosocial support.

Summary: This study found that the experience of losing at least one night of sleep was associated with an increased risk of postpartum psychosis in women with bipolar disorder. Sleep quality in late pregnancy was not associated with postpartum psychosis, and perinatal sleep disruption was not associated with postpartum depression.

Summary: This study systematically reviewed the association between psychological pain and suicidality in patients with major depressive disorder (MDD). The results showed that psychological pain was a risk factor for suicidality in MDD patients, especially for those of advancing age. Reducing psychological pain in MDD patients is important for preventing suicidality.

Summary: This study examined the relationship among family accommodation (FA), posttraumatic stress symptoms (PTSS), and functional impairment. The results showed that FA was significantly associated with PTSS and functional impairment. Baseline FA partially mediated the relationship between baseline PTSS and functional impairment. Changes in FA from pre- to post-treatment were associated with relevant outcome variables at post-treatment and 12-month follow-up.
