The trials were similar in design and collectively included over 50,000 generally vitamin D replete, older men and women. The mega-trials established that vitamin D supplementation with the equivalent of 2000 to 3300 IU/d of vitamin D<sub>3</sub> had no favorable effect on risk of falls or fractures. This review focuses on specific design elements of the trials and how they likely influenced these trial findings. While these trials were in progress, evidence emerged that circulating 25-hydroxyvitamin D levels have a U-shaped association with risk of falling, raising concern about a potential untoward effect of high dose supplementation. There is compelling evidence that in older, vitamin D- and calcium-insufficient nursing home residents, the combination of vitamin D and calcium in modest replacement doses dramatically reduces the risk of hip and other fractures. Community-dwelling older adults in many populous countries around the globe have widespread vitamin D and calcium insufficiency. It is time to follow the evidence trail and determine the effect of vitamin D and calcium replacement on their risk of falls and fractures.</p></div>","PeriodicalId":94141,"journal":{"name":"Metabolism open","volume":"23 ","pages":"Article 100300"},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S258993682400032X/pdfft?md5=465b81989f58807aa537e3f5f2347064&pid=1-s2.0-S258993682400032X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141636691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most clinical guidelines recommend prescribing statins to individuals with type 2 diabetes to reduce the chances of cardiovascular disease.

This systematic review and meta-analysis included articles that met specific inclusion criteria: observational studies such as cross-sectional, cohort, and case-control studies focusing on determinants, risk factors, or correlates associated with statin prescription within Africa. Only published articles up to June 2, 2024, published in English, and conducted in either community or healthcare facility settings were considered. Data import was initially conducted using Microsoft Excel, and statistical analysis was performed using STATA software.

We prospectively included 50 consecutive critically ill adult cases with new onset sepsis and 50 healthy controls matched for age and sex. PTH and 25(OH)D were determined in serum via electrochemiluminescence immunoassays at inclusion in the study in all cases and controls, and one week after sepsis onset in cases. Patients had reduced 25(OH)D compared to controls at sepsis onset (7.9 ± 3 vs 24.6 ± 6.7 ng/mL, p < 0.001), whilst PTH was similar (median (range): 34.5 (5.7–218.5) vs 44.2 (14.2–98.1) pg/mL, p = 0.35). In patients, 25(OH)D upon enrollment and one week after did not differ significantly (7.9 ± 3 vs 7 ± 4.3 ng/mL, p = 0.19).
