Several interventions have been available for preventing and treating osteoporosis. The aim of this study was to systematically review and critically appraise studies that assessed cost-effectiveness of hip protectors for the prevention of hip fractures and to investigate the effects of age, gender and residence situation on cost-effectiveness. A systematic review was conducted in order to identify economic evaluation studies examining the hip protector solely or compared to no treatment according to the Preferred Reported Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. https://www.selleckchem.com/products/Vorinostat-saha.html Synthesis of results was performed to observe trends between the studies. Methodological quality of the studies was assessed by the use of the Quality of Health Economic Studies (QHES) instrument. A total of 15 economic evaluation studies were inclua geriatric ward in a hospital.Hyperkyhosis is thought to be a fall risk factor in older adults. This large study of older men found that fall risk increased with greater kyphosis measured with the blocks method, but did not find an association between kyphosis and falls when measured by the commonly used the Cobb angle method. INTRODUCTION Research suggests an association between hyperkyphosis and falls in community-dwelling older adults, though this has not been investigated within large, population-based studies. This study sought to determine whether two measures of kyphosis prospectively predict fall risk over 3 years among older men. METHODS Within the Osteoporotic Fractures in Men Study (MrOS), we conducted two 3-year prospective studies of 2346 and 2928 men. The first group had kyphosis measured by the Cobb angle at visit 1, while the second group had kyphosis assessed with the blocks method at visit 3; both groups then self-reported falls tri-annually for 3 years. Poisson regression with GEE was used to obtain relative risks (RR) of falls. RESULTS The fall rates over 3 years were 651/1000 person-years among the visit 1 sample (mean age 74 ± 6 years) and 839/1000 person-years among the visit 3 sample (mean age 79 ± 5 years). In adjusted models of the visit 3 sample, the risk of falls was increased by 12% for each standard deviation increase (1.4 blocks) in the number of blocks required to achieve a neutral head and neck position (RR = 1.12, 95% CI = 1.06, 1.18). The Cobb angle was not associated with falls in the visit 1 sample. CONCLUSIONS Although the Cobb angle did not predict falls in community-dwelling older men over 3 years, the blocks method of measuring kyphosis was predictive of falls in this population. This difference could be due to the Cobb angle's focus on thoracic kyphosis, whereas the blocks method may additionally capture abnormal cervical spine curvature.PURPOSE The purpose of this study was to establish a mouse model of proximal fibular osteotomy (PFO), and to determine if PFO could delay degeneration of the medial compartment of the knee joint in a mouse model. METHODS An animal model of destabilization of the medial meniscus (DMM) was used to induce post-traumatic knee osteoarthritis (OA). PFO was performed to examine the effectiveness of PFO on protection against medial compartment knee OA. Micro-CT was used to observe osteosclerosis development in the subchondral bone, and Safranin O-fast green staining was used to evaluate the progression of articular cartilage destruction. The condylar-plateau angle (CPA) and anatomical femorotibial angle (aFTA) were measured to determine whether knee alignment was changed after PFO. RESULTS PFO treatment could decrease osteophyte formation and osteosclerosis development in the subchondral bone, as observed by micro-CT. The value of the ratio of trabecular bone volume to total volume (BV/TV) of DMM+PFO group was lower than that of DMM group. PFO also inhibited the progression of articular cartilage destruction. DMM + PFO group displayed decreased maximal and summed OA scores, as compared with DMM group. Moreover, the change of knee alignment was reduced by PFO, which might be the mechanism of PFO alleviating medial compartment knee OA. CONCLUSION Our results indicated that PFO could alleviate medial compartment knee OA in a mouse model.PURPOSE The purpose of this study was to determine whether the measured size of active gastrointestinal hemorrhage was useful in predicting subsequent positive findings at catheter angiography. MATERIALS AND METHODS This was a single-institution retrospective study consisting of 32 patients with computed tomography angiography (CTA) positive for gastrointestinal bleeding who went on to receive catheter angiography. Each CTA was reviewed, with axial measurements of the anterior-posterior and transverse dimensions of the largest foci of hemorrhage recorded. Volumetric analysis was used to measure the volume of hemorrhage. These measurements were performed for both the arterial and portal venous phases. Additionally, the interval growth between the arterial and portal venous phase was also calculated. RESULTS There was a statistically significant difference in the absolute size of the maximum transverse dimension on portal venous phase imaging (mean = 19.8 mm, p less then 0.001), as well as an interval increase in transverse (mean = 8.5 mm, p less then 0.001) and anteriorposterior (mean = 5.4 mm, p = 0.027) size between arterial and portal venous phases in patients with positive catheter angiography versus negative catheter angiography. There was a statistically significant difference in the volume of hemorrhage on arterial (mean = 1.72 cm3, p = 0.020) and portal venous phases (mean = 5.89 cm3, p = 0.016), as well as an interval change in the size of hemorrhage between the two phases (mean = 4.17 cm3, p = 0.020) in patients with positive catheter angiography versus patients in the negative catheter angiography group. CONCLUSIONS The absolute axial size and volume of hemorrhage, as well as the interval change between the arterial and portal venous phases of CTA imaging is predictive of subsequent positive catheter angiography.
