To study vitamin D status before and after bariatric surgery in women categorized by age: those of childbearing age (under 45 years) and those of non-childbearing age (over 45 years).
Key Findings:
Significant weight loss observed post-surgery with no significant difference in BMI between Wu45 and Wo45 at 24 months.
Serum vitamin D levels increased significantly within 4 months post-surgery but were lower in Wu45 compared to Wo45 at 12 and 24 months.
Baseline vitamin D levels were similar between groups, but Wu45 had lower levels at follow-up, indicating a trend that warrants further investigation.
Interpretation:
Vitamin D levels in women under 45 years of age after bariatric surgery are lower than in those over 45, indicating a need for targeted monitoring and supplementation to address potential deficiencies.
Limitations:
Retrospective, observational nature may introduce bias, affecting the generalizability of results.
Missing data handling could affect the robustness of results, particularly in longitudinal analyses.
Conclusion:
Bariatric surgery significantly impacts vitamin D levels, with younger women experiencing lower levels postoperatively, necessitating careful nutritional management and monitoring.
Machine-learning models distinguished healthy knees from those with osteoarthritis-related cartilage damage, but age and BMI performed as well as or better than the vibration-based models.
