Background: Previous studies reported that vitamin B-12 deficiency is associated with an increased risk of stroke. However, studies examining the association between excessive vitamin B-12 and stroke risk are limited. Our study aimed to investigate the relationship between excessive vitamin B-12 concentrations and risk of stroke and explore whether this association varies according to sex.
Methods: Utilizing the Korean Genome Epidemiology Study (KoGES) prospective cohort data, our primary exposure variables were vitamin B-12 plasma concentration and sex. The occurrence of stroke served as the main outcome of interest. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox regression analysis. An interaction analysis was conducted to assess the interaction effect of vitamin B-12 and sex on stroke incidence.
Results: Cox proportional logistic regression analysis, adjusting for confounders, showed that excessive vitamin B-12 did not significantly alter stroke risk (HR: 1.22, 95% CI: 0.82, 1.71) and revealed no significant sex-based differences in stroke risk (HR: 0.90, 95% CI: 0.75, 1.04). However, interaction analysis indicated that excessive vitamin B-12 was linked to a significant increase in stroke risk in males (HR: 1.81, 95% CI: 1.10, 2.99) but not in females (HR: 1.04, 95% CI: 0.66, 1.60), with statistically significant interaction effect (P < 0.01).
Conclusions: Our study demonstrated that although excessive vitamin B-12 alone does not significantly increase stroke risk, it increases risk in males when considering the interaction with sex.

Zhejiang Cancer Hospital, Hangzhou, Zhejiang, China.
Objective: To observe the clinical efficacy of Dendrobium officinale in the treatment of radiotherapy-induced oral mucositis in nasopharyngeal carcinoma patients, and to explore its regulating effect on immune function and oral microbiota by comparing immune-related factors and oral microbiota before and after the intervention.
Methods: We conducted a randomized double-blinded controlled trial in Zhejiang Cancer Hospital. Sixty patients with nasopharyngeal cancer combined with radiotherapy-induced oral mucositis were randomly divided into a study group and control group, with 30 cases in each group The study group used compound vitamin B12 solution and Dendrobium tea drink, and the control group simply used compound vitamin B12 solution rinse.

Diabetic cognitive dysfunction (DCD) refers to the cognitive impairment observed in individuals with diabetes. Epidemiological studies have suggested that supplementation with n-3 polyunsaturated fatty acid (PUFA) or B vitamins may prevent the development of diabetic complications. Post hoc studies indicate a potential synergistic effect of n-3 PUFA and B vitamins in preventing cognitive impairment.

Background: Vitamin B is an essential micronutrient, aids in synthesis of neurotransmitters, and vital for cognitive function. In the current younger population with more of electronic gadgets and scientific world seems to slow down critical thinking and impairs the trick of comprehensive subjective learning. Vitamin B deficiency has been linked to insulin-resistant state and future cardiovascular risk.

Micronutrient deficiencies (MNDs) are commonly reported after bariatric and metabolic surgery, including laparoscopic sleeve gastrectomy (LSG). Nevertheless, the micronutrient status changes over time and the influence of sex or initial body mass index (BMI) on these changes are less explored. This study aims to investigate the changes in micronutrient levels at 6 and 12 months after LSG and the potential influence of sex or baseline BMI (≥40 kg/m) on these changes in patients submitted to LSG.
