AIM: To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan. METHODS: We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient’s characteristics at PEG using log-rank tests and Cox proportional hazard models. RESULTS: Nine hundred and thirty one patients were followed up for a median of 468 d. A total of 502 deaths were observed (mortality 53%). However, 99%, 95%, 88%, 75% and 66% of 931 patients survived more than 7, 30, 60 d, a half year and one year, respectively. In addition, 50% and 25% of the patients survived 753 and 1647 d, respectively. Eight deaths were considered as PEG-related, and were associated with lower serum albumin levels (P = 0.002). On the other hand, among 28 surviving patients (6.5%), PEG was removed. In a multivariate hazard model, older age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.00-1.03; P = 0.009], higher C-reactive protein (HR, 1.04; 95% CI: 1.01-1.07; P = 0.005), and higher blood urea nitrogen (HR, 1.01; 95% CI: 1.00-1.02; P = 0.003) were significant poor prognostic factors, whereas higher albumin (HR, 0.67; 95% CI: 0.52-0.85; P = 0.001), female gender (HR, 0.60; 95% CI: 0.48-0.75; P < 0.001) and no previous history of ischemic heart disease (HR, 0.69; 95% CI: 0.54-0.88, P = 0.003) were markedly better prognostic factors. CONCLUSION: These results suggest that more than half of geriatric patients with PEG may survive longer than 2 years. The analysis elucidated prognostic factors.

为了提高商业纯钛(CP)的疲劳和摩擦两种性能,开发了低温渗氮工艺。冷轧作为离子渗氮的前处理,能获得细晶粒,加速氮向材料中扩散。用显微维氏硬度计、光学显微镜、扫描电镜(SEM)、X射线衍射(XRD)和背散射电子衍射技术(EBSD)表征冷轧前处理的渗氮样品的显微组织。在大于600℃渗氮的表面上形成钛氮化合物(TiN和Ti2N)。在冷轧预处理的CP钛渗氮后生成的化合物层比单一渗氮的更厚,因此有更高的硬度。低温渗氮(600℃)的试样以应力比R=0.1,室温下做4点弯曲疲劳试验,能抵制晶粒粗化。此外,根据观察显微组织和断裂表面探讨了渗氮CP钛的疲劳断裂机制。
