Dengue is a mosquitoborne viral disease common in regions with tropical climates. Worldwide annual dengue incidence is estimated at [approximately equal to]100 million diagnosed and [approximately equal to]300 million asymptomatic [...]

Despite several guidelines for preventing potentially inappropriate medication (PIM) use in older, their prescription rates remain high (25%). The aim of this study was to determine the impact of medication reviews (MRs) on the drug‐related problems (DRPs) in older patients in Elderly Residential Care Homes (nursing homes [NHs]). DRP was defined as an event or circumstance involving drug therapy that actually or potentially interferes with desired health outcomes. We conducted a retrospective study on 2819 residents of the 46 NHs between 1 January 2017 and 31 December 2018. Drug prescription was analysed according to European EU(7)‐PIM list and START/STOPP list. We then linked each PIM to an appropriate type of DRP. Three months later, we requested the 'updated' drug prescriptions to assess whether the recommendations had been followed. A total of 17 850 prescription lines were registered. A DRP was identified for 25% of them. Following the second request, 13 NHs (28%) responded. About 26% (n = 1188) of the overall prescriptions lines identified as a DRP involved these 13 NHs, which resulted in a recommendation being made during the first MR. Data from the second MR suggested that 53.9% (n = 640) of recommendations were followed with the requested change: 32.0% involved drug withdrawal (n = 381), 9.7% concerned dose adjustment (n = 115) and 6.5% required drug changes (n = 77). Our results show the benefit impact of MR on the quality of drug prescription in older NH residents. MRs should be one of the tools used to improve drug prescriptions in the elderly.

Introduction: Can vitamin D deficiency be predicted by patient questionnaire? Does it lead to secondary hyperparathyroidism that may cause excessive bone resorption? We studied non-osteoporotic subjects in their fifties, in whom vitamin D levels are often tested., Patients and Methods: Patients hospitalised for degenerative osteoarthritis or consulting for assessment of menopause, without renal failure and not treated with vitamin D, completed a questionnaire on sun exposure and underwent measurement of serum calcium, creatinine, 25OH vitamin D, PTH and CTX., Results: Five hundred and twenty-six subjects, mean age 54.6 years (71% women), were investigated throughout the year. 25OH vitamin D levels were correlated with sun exposure and varied according to the month of the year, unlike PTH and CTX levels. From November to May, over 90% of subjects had 25OH vitamin D levels<30ng/mL. Of the subjects who did not expose their face, arms and legs to the sun for at least 20min/day, 94% had 25OH vitamin D levels<30ng/mL. PTH levels were negatively correlated with those of 25OH vitamin D. Serum CTX levels were not correlated with PTH or 25OH vitamin D. Only 13% of subjects presented with secondary hyperparathyroidism, characterised by serum calcium<2.55mmol/L and PTH>65pg/mL, associated with increased CTX levels., Conclusion: Vitamin D deficiency can be predicted by patient questionnaire. It very rarely leads to secondary hyperparathyroidism., (Copyright © 2015. Published by Elsevier Masson SAS.)
