Suboptimal vitamin D status is well reported in sickle cell disease (SCD) patients and associated with a negative impact on health-related quality of life (HRQL). The investigators enrolled 42 SCD patients and 42 healthy controls, subjects within each group received monthly oral vitamin D3 dose according to the baseline status of vitamin D as follows: sufficient: 100,000 IU, insufficient: 150,000 IU, and deficient: 200,000 IU. The investigators assessed safety and efficacy on normalization of vitamin D level, bone mineral density (BMD), hand grip strength (HGS), and HRQL.
This research was designed in accordance to the Method for Efficacy Assessment of Health Food for Bone Heath. Changes to bone density were measured to evaluate the effectiveness of amorphous calcium carbonate in maintaining bone health.
Femur amputated patients often suffer from several problems with conventional socket prosthesis. Some experience changes in gait, discomfort when sitting, altered skin conditions (infection, irritation, rashes, sweat), phantom pain or lack of stabilization between the prosthesis and the residual limb. Many have a low score on "health-related quality of life" questionnaires (HRQL). Some femur amputated patients may be a candidate to osseointegrated prosthesis. Osseointegrated prosthesis is an implant, where the fixture is inserted into the femur canal and an abutment screw, on which the leg-prostheses is inserted, protrudes the skin. By this procedure the patient have a high score on HRQL and experience fewer problems. They have improved gait, reduced discomfort when sitting, increased prosthetic use, and experience fewer skin and pain problems. Femur amputee patients formerly mobilized on socket prosthesis have a reduced bone mineral density in the affected femur and pelvis. The Phd-theses compromise of three studies. The aim of the first study is to follow patients with oosseointegrated prosthesis before and after surgery with DXA-scans to monitor the BMD. In the second study patients will be randomised to receive medical treatment with an RANKL-inhibitor, approved for treatment of osteoporosis, and monitored with DXA, microdialysis and radiostereometry. Depending on the DXA-results patients in the third study may receive fast track rehabilitation. The hypothesis is that patients with osseointegrated prosthesis will have an increased BMD after surgery, 2 years follow up. Patients receiving RANKL inhibitor will have increased BMD, stability of the prosthesis, and some receive fast-track rehabilitation due to high BMD.
This study is to investigate whether the alternating use of Prolia (Denosumab) and Aclasta (Zoledronic acid) can continue to increase bone density.
The study was performed as a prospective, single center study at the Department of Orthopedics, Sacred Heart of Jesus Hospital Vienna, Austria. 117 patients were enrolled in a from January 2016 to May 2017. 53 patients received an isoelastic monoblock cup (RM Pressfit vitamys® Mathys) and 64 patients received a metal- backed modular cup (ANA.NOVA® ImplanTec). Dual-energy x-ray absorptiometry scans according to DeLee and Charnley Zones were performed at time points 0, 3, 6, 12, and 24 months after surgery. The aim of thise study was to compare changes in BMD between an isoelastic monoblock cup and a titanium modular cup. We hypothesized that the more elastic monoblock cup performs better than the more rigid modular cup with regard to changes in BMD.
Dislocated femoral neck fractures are routinely treated with cemented hemiartroplasty and the direct lateral approach (Hardinge) has commonly been used in Norway. The investigators have lately witnessed a significant change in the prefered surgical approaches in total hip arthroplasty (THA) in favor of the posterior and anterior approaches. The direct lateral approach has in THA, more or less, been abandoned in Norway. Numerous studies have reported superior results using the posterior and anterior approahes compared to the lateral approach.
Low bone mineral density affects 77% of children with severe cerebral palsy (GMFCS IV & V) with an increased fracture risk of 4%. One strategy supposed to improve bone mineral density is verticalisation with static devices. Nowadays there is no time recommendation of verticalisation however high intensity verticalisation has been shown to be effective in improving bone mineral density in childrens with cerebral palsy, but difficult to apply in real life due to lack of qualified therapists, device's complexity, and severe impairment in those children. The investigators aim to compare bone mineral density and bone remodelling factors of verticalized and non verticalized childrens with severe cerebral palsy as achieved in everyday life. The investigators conduced a retrospective study comparing bone mineral density and factors who influence bone remolling in severe cerebral palsy's according to whether they are verticalized or not.
Risk-Reducing Salpingo-Oophorectomy (RRSO) at the age of 35 to 45 years is recommended for women with a high genetic risk for ovarian cancer. While this procedure decreases the risk of ovarian cancer by 80-96%, it also results in an immediate menopause. Current research on potential adverse effects of premenopausal risk-reducing salpingo-oophorectomy, such as increased risk of cardiovascular disease, compromised bone health, cognitive dysfunction and reduced quality of life, is limited, mostly due to short follow up. The investigators will conduct a multicenter cross-sectional study nested in a cohort of BRCA mutation carriers from 8 Dutch centers for hereditary cancer. Eligible participants are women who underwent RRSO before the age of 45. The participants will be frequency-matched on current age with women above the age of 55 without RRSO or with RRSO after the age of 55. Participants will complete an online questionnaire containing various questions about lifestyle, medical history, risk factors for cardiovascular disease, bone health, cognition and quality of life. Participants will be asked to visit one of the participating hospitals for a blood test, a cardiovascular assessment and a DEXA scan for determining bone mineral density. Afterwards participants will be requested to perform the online Amsterdam Cognition Scale.
Periprosthetic bone remodeling in femoral neck fracture patients: a 5-year follow up study addressing the influence of surgical approach on periprosthetic bone mineral density.
