Objective: It is anticipated that an intake of vitamin D found acceptable by Endocrine Society Guidelines (10 000 IU/day) with co-administered calcium supplements may result in frequent hypercalciuria and hypercalcaemia. This combination may be associated with kidney stones. The objective of this study was to compare the episodes of hypercalciuria and hypercalcaemia from calcium supplements co-administered with 10 000 IU or 600 IU vitamin D daily. This design allows a comparison of the Institute of Medicine recommendation for the RDA of vitamin D along with the upper limit of calcium intake with the high intake of vitamin D suggested by the Endocrine Society., Context: Harms of currently recommended high intake of vitamin D have not been studied., Design: The design was a randomized controlled trial with 2 groups with evaluation every 3 months for one year: (a) CaCO 3 1200 mg/day with 10 000 IU vitamin D 3 /day or (b) CaCO 3 1200 mg/day with 600 IU vitamin D 3 /day., Patients: This study was conducted in an ambulatory research centre in healthy, white postmenopausal women., Measurements: Serum and 24-hour urine calcium were measured., Results: Hypercalcaemia and hypercalciuria occurred in both groups. At the final visit, 19/48 in the high dose D group had hypercalciuria. The odds of developing hypercalciuria were 3.6 [OR = 3.6(1.39, 9.3)] times higher in the high dose D group. The odds of developing hypercalcaemia did not differ between groups., Conclusions: The safe upper level of vitamin D recommended by the Endocrine Society when accompanied by calcium supplements results in frequent hypercalciuria. The risk of kidney stones at these levels should be investigated., (© 2018 John Wiley & Sons Ltd.)

Background: Though widely discussed, mindfulness-based interventions (MBI) to improve maternal mental health is limited by lack of studies with system incorporation. We evaluate the feasibility of incorporating a MBI program into routine antenatal care (ANC) in Sri Lanka. Methods: MBI included learning mindfulness concepts, practicing mindfulness sitting/reclining meditation, performing mindful movements and practicing mindfulness in daily life. Feedback from the participants were obtained through an anonymous, self-administered, semi-structured questionnaire to determine the program's cultural appropriateness, usefulness, and feasibility. Results: Participants reported that the training reduced the stress of their daily life, brought a sense of calmness to their mind and body, and improved their anger management. Participants felt strongly that this training would be very useful and a shortened version be included in the national ANC program. Conclusions: This pilot study suggests that an interventional study to evaluate system incorporation of a MBI to improve maternal mental health is feasible., Competing Interests: No competing interests were disclosed., (Copyright: © 2019 Agampodi T et al.)

Black Americans have lower levels of serum 25(OH)D but superior bone health compared to white Americans. There is controversy over whether they should be screened for vitamin D deficiency and have higher vitamin D requirements than recommended by the Institute of Medicine (IOM). The purpose of this trial was to determine whether Vitamin D supplementation in elderly black women prevents bone loss. A total of 260 healthy black American women, 60 years of age and older were recruited to take part in a two-arm, double-dummy 3-year randomized controlled trial (RCT) of vitamin D 3 versus placebo. The study was conducted in an ambulatory clinical research center. Vitamin D 3 dose was adjusted to maintain serum 25(OH)D above 75 nmol/L. Bone mineral density (BMD) and serum were measured for parathyroid hormone (PTH), C-terminal crosslink telopeptide (CTX), and bone-specific alkaline phosphatase (BSAP) every 6 months. Baseline serum 25(OH)D 3 was 54.8 ± 16.8 nmol/L. There was no group × time interaction effect for any BMD measurement. For all BMD measurements, except for total body and spine, there was a statistically significant negative effect of time (p < 0.001). An equivalency analysis showed that the treatment group was equivalent to the control group. Serum PTH and BSAP declined, with a greater decline of PTH in the treatment group. The rate of bone loss with serum 25(OH)D above 75 nmol/L is comparable to the rate of loss with serum 25(OH)D at the Recommended Dietary Allowance (RDA) of 50 nmol/L. Black Americans should have the same exposure to vitamin D as white Americans. © 2018 American Society for Bone and Mineral Research., (© 2018 American Society for Bone and Mineral Research.)
