Summary
This study examined whether physical performance and bone and joint diseases were risk factors for falls in 745 men and 1,470 women from the Research on Osteoarthritis/osteoporosis Against Disability (ROAD) study (mean, 69.7 years). Slower walking speed was a risk factor for falls in men and women. Knee pain was a risk factor for falls in women.Introduction
The objective of the present study was to clarify the incidence of falls by sex and age and to determine whether physical performance and bone and joint diseases are risk factors for falls in men and women using a large-scale population-based cohort of the ROAD.Methods
A total of 745 men and 1,470 women were analyzed in the present study (mean age, 68.5 years). A questionnaire assessed the number of falls during 3 years of follow-up. Grip strength and walking speed were measured at baseline. Knee and lumbar spine radiographs were read by Kellgren–Lawrence (KL) grade; radiographic knee osteoarthritis and lumbar spondylosis were defined as KL?=?3 or 4. Knee and lower back pain were estimated by an interview.Results
During a mean follow-up of 3 years, 141 (18.9 %) men and 362 (24.6 %) women reported at least one fall. Slower walking speed was a risk factor for falls in men (0.1 m/s decrease; odds ratio [OR], 1.15; 95 % confidence interval [CI], 1.09–1.23) and women (0.1 m/s decrease; OR, 1.05; 95 % CI, 1.01–1.10). Knee pain was also a risk factor for falls (OR, 1.38; 95 % CI, 1.03–1.84) in women, but lower back pain was not.Conclusion
We examined the incidence and risk factors for falls in men and women. Slower walking speed was a risk factor for falls in men and women. Knee pain was a risk factor for falls in women. 相似文献43.

A 31-year-old woman was transferred to our hospital for treatment of a right pneumothorax. She had presented initially with moderate dyspnea and coughing at a local clinic, where a chest radiograph showed a collapsed right lung. Chest computed tomography showed overinflation of the middle lobe and a large bulla. We diagnosed congenital lobar emphysema of the middle lobe with pneumothorax and performed middle lobectomy by video-assisted thoracic surgery via four ports (5–12 mm in size). The patient had an uneventful postoperative course and was discharged from hospital 5 days after surgery. 相似文献

The aim of the present study was to assess the bone regeneration process in defects introduced into rabbit long bones, which were regenerated with controlled release of recombinant bone morphogenetic protein‐2 (rBMP‐2). The orientation of the biological apatite (BAp) c‐axis and bone mineral density (BMD) were compared as predictors of bone mechanical function. A 20‐mm‐long defect was introduced in rabbit ulnas, and 17 µg of rBMP‐2 was controlled‐released into the defect using a biodegradable gelatin hydrogel as the carrier. In the bone regeneration process, two characteristic phases may have been governed by different factors. First, new bone formation actively occurred, filling the bone defect with newly formed bone tissue and increasing the BMD. This process was regulated by the strong osteoinductive capacity of rBMP‐2. Second, after filling of the defect and moderate BMD restoration, preferential BAp c‐axis orientation began to increase, coincident with initiation of remodeling. In addition, the BAp c‐axis orientation, rather than BMD, was strongly correlated with Young's modulus, an important index of bone mechanical function, particularly in the later stage of bone regeneration. Thus, preferential BAp c‐axis orientation is a strong determinant and predictor of the mechanical function of tissue‐engineered bone. Therefore, analysis of BAp preferential c‐axis orientation in addition to measurement of BMD is crucial in assessment of bone mechanical function. © 2013 American Society for Bone and Mineral Research © 2013 American Society for Bone and Mineral Research 相似文献

Background
Minimal change disease (MCD) is the most common cause of nephrotic syndrome in children and is associated with the expression of CD80 in podocytes and the increased excretion of CD80 in urine. We hypothesized that serum from patients with MCD might stimulate CD80 expression in cultured podocytes.Methods
Sera and peripheral blood mononuclear cells (PBMCs) were collected from subjects with MCD in relapse and remission and from normal controls. Immortalized human podocytes were incubated with culture media containing patient sera or supernatants from patient and control PBMC cultures. CD80 expression was measured by quantitative PCR and western blot analysis.Results
Sera collected from patients with MCD in relapse, but not in remission, significantly increased CD80 expression (mean ± standard deviation: 1.8?±?0.7 vs. 0.8?±?0.2; p?<?0.004) and CD80 protein secretion by podocytes (p?<?0.05 between relapse and normal controls). No such CD80 increase was observed when podocytes were incubated with supernatants of PBMC cultures from patients in relapse.Conclusions
Sera from MCD patients in relapse, but not in remission, stimulated CD80 expression in cultured podocytes. Identifying this factor in sera could provide insights into the pathogenesis of this disorder. No role in CD80 expression by podocytes was found for cytokines released by PBMCs. 相似文献46.

Background
Epidermal growth factor receptor (EGFR) signaling is one of the most promising targets for molecular-targeted therapies in esophageal squamous cell carcinoma (ESCC). Thus, the molecular diagnosis of KRAS and BRAF mutations is clinically important in therapeutic decision making. However, the frequency of KRAS and BRAF mutations in ESCCs remains inconclusive because of the limited sample sizes of previous studies (all N ≤ 80). Pyrosequencing is a nonelectrophoretic nucleotide extension sequencing technology that can be used for mutation testing.Methods
The frequency of KRAS and BRAF mutations was examined using a nonbiased database of 203 resected ESCCs and a high-throughput pyrosequencing assay.Results
The validity of the KRAS pyrosequencing method was initially demonstrated by detection of all 4 types of KRAS mutations [c.35G>T (codon 12 GGT>GTT), c.35G>A (codon 12 GGT>GAT), c.34G>T (codon 12 GGT>TGT), c.38G>A mutation (codon 13 GGC>GAC)], which had been previously diagnosed using Scorpion-ARMS technology, in 9 colon cancer tissues (9 of 9; 100 %). Similar results were demonstrated for BRAF mutational status in 3 colon cancer cell lines (HCT116, Colo201, and HT29), which were validated by Sanger dideoxy sequencing. Subsequently, the KRAS mutation was found to be extremely rare (1 of 203; 0.5 %), and the BRAF mutation was absent (0 of 203; 0 %), in the dataset of 203 ESCCs.Conclusions
These results suggest that KRAS and BRAF mutations play a limited role in the development of ESCC and that mutation analysis is not useful as a screening test for sensitivity to anti-EGFR therapy in ESCC.47.

We proposed a novel surface modification for an artificial hip joint stem from the viewpoint of maintenance and establishment of appropriate bone function and microstructure, represented by the preferred alignment of biological apatite (BAp) and collagen (Col). Oriented grooves were introduced into the proximal medial region of the femoral stem to control the principal stress applied to the bone inside the grooves, which is a dominant factor contributing to the promotion of Col/BAp alignment. The groove angle and the stem material were optimized based on the stress inside the grooves through a finite element analysis (FEA). Only the groove oriented proximally by 60° from the normal direction of the stem surface generated the healthy maximum principal stress distribution. The magnitude of the maximum principal stress inside the groove decreased with increasing the stem Young's modulus, while the direction of the stress did not largely changed. An in vivo implantation experiment showed that this groove was effective in inducing the new bone with preferential Col/BAp alignment along the groove depth direction which corresponded to the direction of maximum principal stress inside the groove. The anisotropic principal stress distribution and the oriented microstructure inside the groove are similar to those found in the femoral trabeculae; therefore, the creation of the oriented groove is a potent surface modification for optimizing implant design for a long-term fixation. 相似文献

Quantitative analysis of the orientational distribution of biological apatite (BAp) crystals is proposed as a new index of bone quality. This study aimed to analyze BAp c-axis orientation in ovariectomized (OVX) monkeys treated with amino-bisphosphonates minodronic acid and alendronate as reference. Sixty female monkeys aged 9–17 years were divided into five groups: one sham group and four OVX groups. The sham group and one OVX group were treated daily with vehicle for 17 months. The other three groups were treated daily with minodronic acid at doses of 0.015 and 0.15 mg/kg, and alendronate at 0.5 mg/kg orally, respectively. The seventh lumbar vertebrae were subjected to analysis of the preferential BAp c-axis orientation in the ventral cortical bone. The BAp c-axis orientation along the craniocaudal axis was significantly increased in the OVX monkeys. The high dose of minodronic acid suppressed the OVX-induced increase in the BAp c-axis orientation, whereas alendronate showed a non-significant tendency to suppress the increase in the orientation. In analysis with other parameters, the BAp c-axis orientation was positively correlated with bone formation indices in biochemical markers and bone histomorphometry and negatively correlated with the increase in lumbar bone mineral density. On the other hand, the BAp c-axis orientation was not correlated with bone resorption indices, except for the eroded surface. These results indicate that the increase in BAp c-axis orientation was ameliorated by minodronic acid treatment in OVX monkeys, mainly by suppression of bone formation increase. 相似文献
