Evidence That Increasing Serum 25(OH)D Concentrations to 30 ng/mL in the Kingdom of Saudi Arabia and the United Arab Emirates Could Greatly Improve Health Outcomes
Biomedicines. 2023 Mar 23;11(4):994. doi: 10.3390/biomedicines11040994.ABSTRACTAccumulating evidence supports the potential protective effects of vitamin D against chronic diseases such as Alzheimer's disease, autoimmune diseases, cancers, cardiovascular disease (ischaemic heart disease and stroke), type 2 diabetes, hypertension, chronic kidney disease, stroke, and infectious diseases such as acute respiratory tract diseases, COVID-19, influenza, and pneumonia, as well as adverse pregnancy outcomes. The respective evidence is based on ecological and observational studies, randomized controlled trials, mechanistic studies, ...

Assessment of Vitamin D Deficiency in Patients with Neurological Disorders (P03.271)
CONCLUSIONS: The results of the present study may have been biased by the type of the study population (hospital-based) and the small size of the sample. However, the frequent association between Vitamin D deficiency and neurologic disorders indicates that this vitamin may have a fundamental role in physiologic and pathological processes of the Nervous System, particularly in patients over 65 years of age. Vitamin D deficiency should be investigated routinely in clinical practice as the detection of this parameter may have important therapeutic implications.Disclosure: Dr. Triggiani has nothing to disclose.

Vitamin D, arterial hypertension & cerebrovascular disease.
Vitamin D, arterial hypertension & cerebrovascular disease. Indian J Med Res. 2013 Apr;137(4):669-679 Authors: Kienreich K, Grubler M, Tomaschitz A, Schmid J, Verheyen N, Rutters F, Dekker JM, Pilz S Abstract Vitamin D is mainly derived from endogenous ultraviolet-B induced vitamin D synthesis in the skin, and the current high prevalence of vitamin D deficiency can, therefore, largely be attributed to lifestyle related low sunlight exposure. Regulation of bone and mineral metabolism is a classic vitamin D effect, but the identification of the vitamin D receptor (VDR) in almost all human cells suggests ...

Lack of vitamin D may 'raise dementia risk'
Conclusion This cohort study of more than 1,650 elderly people has found that over 5.6 years, severe vitamin D deficiency is associated with approximately twice the risk of developing dementia or Alzheimer's disease. It also found moderate deficiency is associated with a 50% increase in risk compared with healthy levels of vitamin D. With this being a cohort study, it was not able to show that low levels of vitamin D caused dementia or Alzheimer's disease – it was simply able to show an association. Other factors that can increase the risk of developing dementia, such as a poor diet, lack of activity and general poor h...

Normocalcaemic, vitamin D sufficient hyperparathyroidism ‐ high prevalence and low morbidity in the general population A long‐term follow‐up study, the WHO MONICA project, Gothenburg, Sweden
ConclusionsThis small random population study showed that nHPT was common, 11% at follow‐up. Only one individual developed mild hypercalcaemia in 13 years. Previous S‐PTH was predictive of nHPT and hypertension was prevalent, but no increase in hard end points was seen over a 17‐year period.This article is protected by copyright. All rights reserved.

Low vitamin D status in relation to cardiovascular disease and mortality in Swedish women – Effect of extended follow-up
Conclusion Low 25D status increased the risk for all endpoints, but a lengthy follow-up diminished these risks towards the null. The impact of follow-up depends on the outcome. Future studies of 25D and disease should use repeated 25D assessments.

Editorial: Telomeres and Epigenetics in Endocrinology
This study was hypothesis-driven; the genetic variants were selected for being previously and substantially genotyped. The big sample size and the rich panel of other biomarkers allowed the authors to conduct much more detailed analyses on this topic. The third article by Provenzi et al. proposed their perspectives on the role of telomeres in premature birth and discussed the potential implications for early adversity and care in the neonatal intensive care unit (Pavanello et al.). Indeed, the speculation of telomeres in aging begins in the premature aging syndrome. It is thus interesting to examine if telomeres also play...

Interventions for preventing bone disease in kidney transplant recipients.
CONCLUSIONS: Bisphosphonate therapy may reduce fracture and bone pain after kidney transplantation, however low certainty in the evidence indicates it is possible that treatment may make little or no difference. It is uncertain whether bisphosphonate therapy or other bone treatments prevent other skeletal complications after kidney transplantation, including spinal deformity or avascular bone necrosis. The effects of bone treatment for children and adolescents after kidney transplantation are very uncertain. PMID: 31637698 [PubMed - as supplied by publisher]

Vitamin D, Marine n-3 Fatty Acids, and Primary Prevention of Cardiovascular Disease Current Evidence.
Abstract Whether marine omega-3 fatty acid (n-3 FA) or vitamin D supplementation can prevent cardiovascular disease (CVD) in general populations at usual risk for this outcome is unknown. A major goal of VITAL (Vitamin D and Omega-3 Trial) was to fill this knowledge gap. In this article, we review the results of VITAL, discuss relevant mechanistic studies regarding n-3 FAs, vitamin D, and vascular disease, and summarize recent meta-analyses of the randomized trial evidence on these agents. VITAL was a nationwide, randomized, placebo-controlled, 2×2 factorial trial of marine n-3 FAs (1 g/d) and vitamin D3 (2000 IU...

Telling friend from foe in emergency vertigo and dizziness: does season and daytime of presentation help in the differential diagnosis?
The objective of the present study was to analyze frequency and distribution patterns of specific vestibular and non-vestibular diagnoses in an interdisciplinary university emergency room (ER), including data on daytime and season of presentation. A retrospective chart analysis of all patients seen in a one-year period was performed. In the ER 4.23% of all patients presented with VD (818 out of 19,345). The most frequent-specific diagnoses were BPPV (19.9%), stroke/transient ischemic attack (12.5%), acute unilateral vestibulopathy/vestibular neuritis (UVH; 8.3%), and functional VD (8.3%). Irrespective of the diagnosis, the...

The severity of vasomotor symptoms and number of menopausal symptoms in postmenopausal women and select clinical health outcomes in the Women's Health Initiative Calcium and Vitamin D randomized clinical trial
This study evaluated whether vasomotor symptom (VMS) severity and number of moderate/severe menopausal symptoms (nMS) were associated with health outcomes, and whether calcium and vitamin D (CaD) modified the risks. Methods: The Women's Health Initiative CaD study was a double blind, randomized, placebo-controlled trial, which tested 400 IU of 25-hydroxyvitamin-D and 1,000 mg of calcium per day in women aged 50 to 79 years. This study included 20,050 women (median follow-up of 7 y). The outcomes included hip fracture, colorectal cancer, invasive breast cancer, all-cause mortality, coronary heart disease, stroke, cardi...

Study: Fish Oil Doesn ’ t Seem To Prevent Heart Problems
This study is consistent with earlier trials. The US Food and Drug Administration approved the fish oil-based drug Vascepa for heart attack and stroke prevention in 2019. Nissen hopes the FDA will take a look at these studies and reconsider that decision. “But it’s hard to get something undone once the genie gets out of the bottle,” he said. An editorial in the journal that accompanies the study written by Dr. Gregory Curfman, assistant professor of medicine at Harvard Medical School, also suggested the FDA should require a postmarketing clinical trial of a high-dose of fish oil, such as Vascepa, vs. corn...

E-061 Moyamoya syndrome patients have low vitamin D
ConclusionOur data indicate a large proportion of moyamoya syndrome patients are deficient in vitamin D, which we hypothesize contributes to pathological severity. Future studies incorporating vitamin D supplementation may act as a novel intervention for this patient population that currently has few treatment options.Disclosures J. Fraser: None. L. Whitnel: None. J. Roberts: None.
