Psychosocial rehabilitation and satisfaction with life in adults with childhood-onset of end-stage renal disease

Little information is available on vocational rehabilitation and satisfaction with the quality of life in adult patients with early onset of end-stage renal disease (ESRD). A sample of 39 patients (mean age =26.7±6, range, 18 to 43 years, n =13 on dialysis, n =26 transplanted successfully) were required to report data on their vocational qualification and employment, and their degree of general and health-related satisfaction with life was surveyed. Data on psychosocial rehabilitation were collected by a structured questionnaire, whereas satisfaction with the quality of life was assessed with the standardized Questionnaire on Satisfaction in Life (FLZ). Fifty-eight percent of the patients had left school with certificates equivalent to high school graduation, 87% had completed vocational training and 67% were in paid employment. Forty-nine percent lived on their own or with a partner and 72% fully or partly earned their own living. The mean general and health-related satisfaction with life is significantly reduced compared to the general population. The patients were least satisfied in the areas partnership/sexuality and family life/offspring in general, as well as physical condition and ability to relax within health-orientated satisfaction. Final mean body height was 167.6±11.9 (SDS –1.54±1.59) for male and 153.77±8.29 for female patients (SDS –1.58±1.54). Thirty-six percent reported to be dissatisfied with their present body height compared to 4% of age-matched healthy controls. Positive perception of quality of life was significantly correlated to satisfaction with adult height ( r =0.41, P =0.008). Vocational rehabilitation of adult patients with early onset of ESRD achieves lower values than among the general population, however, more favorable percentages than among young adult patients or patients with adult onset of ESRD. The patients self-evaluation of both their general and health-related quality of life proves to be clearly muted, which is a clear indication of the physical and psychological strain of living with a chronic disease.     

10 November 2009: In-Depth Oral Presentations and Oral Communications

Background  To date, there have been no published studies of the degenerative changes in the cervical spine in adult idiopathic scoliosis patients with thoracic and lumbar curves severe enough to require major reconstructive surgery. Materials and methods  The primary study group was 48 adult patients who had previously undergone a fusion from T10 or higher to the sacrum as an adult for idiopathic scoliosis. These were compared to 38 adults with unfused idiopathic scoliosis of 30°–50° and to 42 symptomatic adults presenting with cervical pain. Cervical degeneration was assessed using a new cervical degenerative index (CDI). Results  The amount of degenerative change seen in the cervical spine in the long-fusion group was significantly higher at baseline (just prior to the fusion) than the two control populations and became much higher at a mean follow-up of 8.5 years. Conclusions  This unique subgroup of patients, those having fusion from the thoracic spine to the sacrum as adults for adolescent idiopathic scoliosis, had a high incidence and severity of degenerative changes in their cervical spine. Due to the presence of advanced cervical degenerative changes prior to the fusion, it is not possible to blame the fusion as the main cause for these findings. These changes are either related to the thoracic and lumbar deformities or are more likely due to this subgroup having a higher natural propensity for degenerative changes.

NADPH氧化酶介导的ROS在特发性炎性肌病动物模型骨骼肌组织中的表达及意义

目的 探讨NADPH氧化酶中的NOX2和NOX4介导的活性氧（ROS）在特发性炎性肌病（IIM）发病机制中的作用及意义。方法将14只健康雌性BALB/c小鼠随机分为对照组（n=6)和EAM组（n=8）,EAM组小鼠采用豚鼠骨骼肌匀浆蛋白免疫诱导实验性自身免疫性肌炎动物模型。观察小鼠的体重变化、临床表现,测定其血清肌酶水平、四肢肌力及骨骼肌组织病理改变;并采用免疫组织化学法、分光光度法和ELISA法分别检测各组小鼠骨骼肌组织中NOX2、NOX4、NADPH及ROS的表达情况或含量。结果 与对照组相比,末次免疫后1周EAM组小鼠体重下降,差异有统计学意义（P＜0.05）。HE染色结果显示,对照组小鼠骨骼肌纤维大小、形态、结构基本正常,有少量炎性细胞浸润,未见肌纤维萎缩、变性、坏死;EAM组小鼠骨骼肌纤维大小不一、粗细不等,有大量炎性细胞浸润,可见不同程度的萎缩、变性、坏死;EAM组小鼠骨骼肌组织HE染色病理学评分显著高于对照组（P＜0.05）。与对照组相比,EAM组小鼠骨骼肌组织中NADPH含量降低、ROS含量升高（P＜0.05）。免疫组化染色结果显示,NOX2和NOX4在EAM组小鼠骨骼肌组织中的表达均高于对照组（P＜0.05）。Pearson相关分析结果显示,EAM组小鼠骨骼肌组织中ROS的含量与NOX2、NOX4的免疫组化评分均呈正相关（P＜0.05）,而与NADPH的含量呈负相关（P＜0.05）;EAM组小鼠骨骼肌组织HE染色病理学评分与NOX2、NOX4的免疫组化评分及ROS的含量均呈正相关（P＜0.05）,而与NADPH的含量呈负相关（P＜0.05）。结论 NADPH氧化酶中的NOX2和NOX4可能通过消耗NADPH产生大量的ROS,导致组织细胞氧化性损伤并诱导铁死亡反应来参与IIM的发病;NADPH、NOX2、NOX4和ROS有望成为新的评价IIM肌肉组织损伤程度的指标。
