No significant effect on bone mineral density by high doses of vitamin D3 given to overweight subjects for one year

<p>Abstract</p> <p>Background</p> <p>In meta-analyses supplementation with vitamin D appears to reduce incidence of fractures, and in cross-sectional studies there is a positive association between serum 25-hydroxyvitamin D (25(OH)D) levels and bone mineral density (BMD). However, the effect of supplementation with high doses of vitamin D on BMD is more uncertain and could in theory have both positive and negative effects.</p> <p>Methods</p> <p>The study was a one year, double blind placebo-controlled intervention trial performed at the University Hospital of North Norway. 421 subjects, 21 - 70 years old, were included and 312 completed the study. The subjects were randomized to vitamin D₃40.000 IU per week (DD group), vitamin D₃20.000 IU per week (DP group), or placebo (PP group). All subjects were given 500 mg calcium daily. Serum 25(OH)D, osteoprotegrin (OPG), receptoractivator of nuclear factor-kappaB ligand (RANKL), and BMD at the lumbar spine and the hip were measured before and at the end of the study.</p> <p>Results</p> <p>At baseline the mean serum 25(OH)D levels were 58 nmol/L (all subjects) and increased to 141 and 100 nmol/L in the DD and DP groups, respectively. After one year, no significant differences were found between the three groups regarding change in BMD, serum OPG or RANKL.</p> <p>Conclusions</p> <p>Supplementation with high doses of vitamin D for one year does not appear to have a negative effect on BMD in healthy subjects. In order to disclose a positive effect, subjects with low BMD and/or low serum 25(OH)D levels need to be studied.</p> <p>Trial registration</p> <p>The trial was registered at ClinicalTrials.gov (NCT00243256).</p

Which factors influence the prevalence of institution‐acquired falls? Results from an international, multi‐center, cross‐sectional survey

Purpose: Falls are a highly prevalent problem in hospitals and nursing homes with serious negative consequences such as injuries, increased care dependency, or even death. The aim of this study was to provide a comprehensive insight into institution-acquired fall (IAF) prevalence and risk factors for IAF in a large sample of hospital patients and nursing home residents among five different countries. Design: This study reports the outcome of a secondary data analysis of cross-sectional data collected in Austria, Switzerland, the Netherlands, Turkey, and the United Kingdom in 2017 and 2018. These data include 58,319 datapoints from hospital patients and nursing home residents. Methods: Descriptive statistics, statistical tests, logistic regression and generalised estimating equation (GEE) models were used to analyse the data. Findings: IAF prevalence in hospitals and nursing homes differed significantly between the countries. Turkey (7·7 %) had the highest IAF prevalence rate for hospitals and Switzerland (15·8 %), for nursing homes. In hospitals, our model revealed that IAF prevalence was associated with country, age, care dependency, number of medical diagnoses, surgery in the last two weeks, and fall history factors. In nursing homes, care dependency, diseases of the nervous system, and fall history were identified as significant risk factors for IAF prevalence. Conclusions: This large-scale study reveals that the most important IAF risk factor is an existing history of falls, independent of the setting. Whether a previous fall has occurred within the last 12 months is a simple question that should be included on every (nursing) assessment at the time of patient or resident admission. Our results guide the development of tailored prevention programs for persons at risk of falling in hospitals and nursing homes

Bone mineral density and body composition in postmenopausal women with psoriasis and psoriatic arthritis

Introduction: the aim of the present study was to compare bone mineral density (BMD) and body composition (BC) measurements as well as identify risk factors for low BMD and osteoporotic fractures in postmenopausal women with psoriasis (Ps) and psoriatic arthritis (PsA).Methods: A cross-sectional study was carried out in 45 PsA women, 52 Ps women and 98 healthy female controls (HC). Clinical risk factors for low bone density and osteoporotic fracture were evaluated by a specific questionnaire. An X-ray absorptiometry (DXA) at the lumbar spine, total femur and total body was performed on all patients. Skin and joint outcomes were measured by specific tools (PASI, HAQ and DAS28). Morphometric vertebral fractures were evaluated by lumbar and thoracic spine X-ray, according to Genant's method.Results: There were no significant differences in age, body mass index (BMI), total lean mass and bone mineral density among the groups. However, the PsA group had a significantly higher body fat percentage (BF%) than the Ps and HC groups. Osteoporotic fractures were more frequently observed in PsA and Ps groups than in the HC group (P = 0.01). Recurrent falls and a longer duration of disease increased the risk of fracture (odds ratio (OR) = 18.3 and 1.08, respectively) in the PsA group (P = 0.02). Disability was the main factor related to osteoporotic fracture in the Ps group (odds ratio (OR) = 11.1) (P = 0.02).Conclusions: Ps and PsA patients did not present lower BMD. However, they had a higher prevalence of osteoporotic fractures and higher risk of metabolic syndrome. Patients with a longer duration of disease, disability and recurrent falls need preventive measures.Rheumatology Division at UNIFESP/EPMUniversidade Federal de São Paulo, UNIFESP Paulista Sch Med, Div Rheumatol, EPM, BR-04023900 São Paulo, BrazilUniversidade Federal de São Paulo, UNIFESP Paulista Sch Med, Div Rheumatol, EPM, BR-04023900 São Paulo, BrazilWeb of Scienc

Urinary incontinence prevalence and management in nursing homes in Austria, the Netherlands, Turkey and the United Kingdom:A multi-site, cross-sectional study

OBJECTIVES: The aim of this study is to describe and compare the prevalence rates of urinary incontinence as well as the management of urinary incontinence in the nursing home setting in Austria, the Netherlands, Turkey and the UK.METHODS: This study is a secondary analysis of the 2017 and 2018 data from a multi-site, cross-sectional study which is performed annually in the nursing home setting in Austria, the Netherlands, Turkey and the UK.RESULTS: A total of 23,334 nursing home residents was included in this study, most of whom were female. The urinary incontinence prevalence rates ranged from 13.8% in Turkey to 35.1% in Austria. In all countries, the most frequently used intervention for urinary incontinence management was the use of absorbent products and/or catheters (ranging from 81% in Turkey to 94.5% in Austria). The countries differed with regard to the methods used to assess the type of urinary incontinence, scheduled individual bathroom visits and medication evaluation. In the UK (77.1%), scheduled individual bathroom visits were a more frequent measure than in Austria (51.3%), the Netherlands (24.4%) and Turkey (10.2%).CONCLUSION: The most frequently used nursing intervention in all countries was the use of absorbent products and/or catheters. Future studies on the over- or misuse of these products are warranted. In order to avoid the over- or misuse of these products in the nursing home setting, the use of the evidence- and consensus-based algorithm provided by the Wound, Ostomy and Continence Nurses Society™ is recommended.</p

Secukinumab treatment in new-onset psoriasis: aiming to understand the potential for disease modification – rationale and design of the randomized, multicenter STEPIn study

Background: To date, biological treatments have been assessed in subjects with a long-term history of psoriasis and previous failures to systemic and topical therapies. In rheumatoid arthritis and other immune-mediated inflammatory diseases, early intensive systemic treatment prolongs treatment-free remission. We hypothesize that, by treating patients with psoriasis early with an effective systemic therapy, we may be able to alter the clinical outcome and the natural course of the disease. The STEPIn study (NCT03020199) investigates early intervention with secukinumab versus narrow-band ultraviolet B (nb-UVB) phototherapy in subjects with new-onset psoriasis. Objective: To determine whether early intervention with either nb-UVB treatment or secukinumab in subjects with new-onset plaque psoriasis might modify the natural course of the disease. Methods: One hundred and sixty subjects aged 18–50 years with new-onset (≤12 months) moderate-to-severe plaque psoriasis and naïve to systemic treatment and phototherapy will be randomized to secukinumab 300 mg or nb-UVB. The Main Study has two treatment arms: Arm A1, subcutaneous secukinumab 300 mg at baseline, Weeks 1, 2, 3 and 4, and every 4 weeks thereafter until and including Week 52; Arm B1, one/two cycles of nb-UVB for 12 weeks each (maximum 28-week break between cycles). After treatment discontinuation, patients will be followed up and monitored for disease activity up to Week 208. A Mechanistic Sub-study will assess immunological changes and pathogenic tissue-resident memory T cells in skin biopsies. Conclusions: STEPIn is the first study to investigate whether early intensive treatment in new-onset psoriasis can modify the long-term natural course of the disease and thus become a novel treatment strategy for patients with psoriasis
