Effects of an exercise intervention for older heart failure patients on caregiver burden and emotional distress.

BACKGROUND: The impact of exercise programmes for heart failure on those close to the patient is largely unknown. We examined the effect of a hospital and home-based exercise intervention on burden, anxiety and depression of informal caregivers. DESIGN: The study was a randomized, controlled trial. Heart failure patients were randomized to a seated 12-week hospital-based exercise programme. Caregiver measures were gathered at baseline, 3 months later and 6 months following baseline. METHODS: Sixty caregivers (mean age 63.4 years, 65% female) of heart failure patients (n = 82, mean age 80.5 years, 44% female) participating in a trial of an exercise intervention were recruited. Caregiver burden, anxiety and depression were assessed. RESULTS: There were no differences in caregiver burden, depression or anxiety between the two groups of caregivers at baseline (caregiver burden, patient control 33.1 versus patient exercise 34.1; anxiety 4.1 versus 5.5; depression 2.8 versus 3.8). At 3 months there were no differences between caregivers in the two groups on outcomes. At 6-month follow-up caregivers of heart failure patients in the exercise group had burden scores that were significantly worse than the control group. There were no differences between the carers of exercise and control groups in anxiety and depression. Levels of anxiety and depression in the entire carer sample were marginally higher than reference values in a healthy non-clinical sample. CONCLUSION: The present exercise interventions for frail older patients did not benefit caregivers and was associated with an increase in caregiver burden. We suggest that future exercise interventions for heart failure patients should actively incorporate informal caregivers into research designs.     

亚低温治疗颅脑损伤延长翻身间隔时间与压疮关系的研究

[目的]探讨颅脑损伤病人应用亚低温治疗仪时具体间隔多长时间翻身不发生压疮.[方法]随机选择45例颅脑损伤应用亚低温治疗的病人,采取3 h后开始翻身,侧卧位时每次均为1 h,以后平卧位时间每次逐渐递增1/2 h.[结果]在应用亚低温治疗期间除3例病人在不同时段内发生轻微紫色冻伤外,所有病例均未发生压疮,平均翻身间隔时间为11.31 h,应用单样本统计学处理,有统计学意义(t=8.867,P<0.005).[结论]颅脑损伤病人在使用亚低温治疗过程中翻身间隔时间可以延长至8 h不发生压疮.     

Immunological responses to pneumococcal vaccine in frail older people

Advanced age has been associated with a wide range of defects in both the innate and adaptive immune systems including diminished specific antibody responses that increase the risk of invasive pneumococcal disease (IPD) and limit the effectiveness of vaccines. However, the elderly are a heterogeneous group and measures of overall frailty may be a better indicator of disease susceptibility (or vaccine response) than chronological age alone.

国人胎儿胸腺的生长发育

称量了14—38周共56例引产胎儿胸腺的重量并观察了6—38周共25例引产胎儿胸腺的组织结构,认为胸腺在胚胎时期生长速度较快。光镜观察,6周已出现胸腺的始基,第9周开始出现淋巴细胞,12周开始分叶,13周以后,皮质髓质渐趋分明并出现胸腺小体,15周后胸腺小叶增多变宽,新小叶形成旺盛,胸腺小体增多,至28周后结构已近似成熟。     

Extragastrointestinal stromal tumor possibly originating from the prostate

We report a case of extragastrointestinal stromal tumor possibly originating from the prostate. The patient underwent radical prostatectomy because of no metastatic evidence. No recurrence and metastasis have been found during 14 months of follow up. To our knowledge, this may be the third such case published in a report in terms of pathological type.     

CT引导下颈侧入路舌咽神经毁损术

目的探讨CT引导下颈侧入路舌咽神经毁损术对舌咽神经痛及舌咽神经支配区顽固性疼痛的疗效. 方法 A组16例舌咽神经痛及B组12例舌咽神经支配区顽固性疼痛,采用CT引导经皮穿刺定位于茎突前缘第2颈椎水平,注入局麻药仅阻滞舌咽神经,注入7%苯酚甘油溶液0.8 ml. 结果 A组完全缓解率87.5%(14/16),总有效率100%(16/16),随访6个月无复发;B组完全缓解率50%(6/12),总有效率83.3%(10/12),随访6个月,复发6例(50.0%).2组均无严重并发症. 结论 CT介导下颈侧入路舌咽神经毁损术具有疗效可靠,定位准确,操作安全的特点,并有效减少严重并发症的发生.
