Assessment of long-term quality of life after laparoscopic and open surgery for Crohn''s disease

OBJECTIVE: Surgery for Crohn's disease (CD) is associated with a high recurrence rate and quality of life (QOL) in these patients is controversial. The aim of this study was to assess QOL in patients after laparoscopic and open surgery for CD by two different validated instruments, a generic nonspecific score and a specific gastrointestinal QOL index. PATIENTS AND METHODS: Patients with CD who underwent elective laparoscopic or open ileocaecal resection with primary anastomosis between 1992 and 2000 were followed for recurrence and surgery-related complications. QOL was assessed by the SF-36 Health Survey containing a mental (MCS) and a physical (PCS) component summary score and by the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch. RESULTS: Thirty-seven patients with a mean age of 48.8 +/- 18.4 years including 23 females and 14 males were evaluated at a mean follow-up of 42.6 +/-25.8 months (minimum of 8 months). Twenty-one (57%) patients underwent laparoscopic resection and 16 (43%) open surgery. Both groups were well matched for age, gender, ASA class and body mass index. Fourteen (38%) patients developed recurrent disease and 3 (8%) had postoperative incisional hernias. Overall, QOL scores were 103 +/- 26.8 for the GIQLI, 47.2 +/- 11.8 for the PCS, and 49.2 +/- 11.5 for the MCS. The GIQLI correlated well with the SF36, correlation coefficient = 0.68 for GIQLI vs PCS (95% CI, 0.41,0.95) and 0.67 for GIQLI vs MCS (95%CI, 0.39, 0.95), respectively. When compared to the general US population, mean GIQLI scores (-13.8, P = 0.002) and mean PCS scores (-4.7, P = 0.001) were significantly lower in these patients than in healthy individuals. In a multivariate analysis of impact factors on QOL, recurrence within the follow-up period was the single significant determinant reducing the PCS (-35.1, P = 0.026) and the GIQLI (-36.1, P = 0.018). CONCLUSION: QOL is significantly reduced in patients with CD at long-term follow-up after both laparoscopic and open surgery. Recurrence is the only factor adversely affecting QOL of CD patients in remission irrespective of the operative technique applied.     

Early assessment of renal resistance index after kidney transplant can help predict long-term renal function.

BACKGROUND: Color Doppler ultrasonography of intrarenal arterial resistance index (RI), performed early after kidney transplant, has proven to reliably predict short-term allograft function. The aim of this study was to assess whether it could also predict long-term renal function. METHODS: We retrospectively analysed 76 kidney transplant patients who underwent RI assessment within 1 month after the transplant, subdivided into two groups according to RI values, lower (group A) or higher (group B) than its median value (0.635). RESULTS: Compared with group A subjects, the patients of group B were older at the time of transplant (42 +/- 9 vs 35 +/- 8 years; P = 0.001), the donor age was also older (41 +/- 16 vs 33 +/- 13 years; P = 0.02) and had a slightly higher proteinuria (0.54 +/- 0.5 vs 0.32 +/- 0.2 g/24 h; P = 0.02). Serum creatinine, ciclosporin or tacrolimus trough level, arterial blood pressure, number of human leukocyte antigen (HLA) mismatches, anti-hypertensive medications and incidence of delayed graft function were not significantly different between the two groups. By univariate analysis, RI turned out to directly correlate with the recipient age, donor age and daily proteinuria (P = 0.007, P = 0.0007 and P = 0.02, respectively). Multivariate analysis showed that only donor and recipient age maintained their independent predictive value on RI. Kaplan-Meier analysis, considering a serum creatinine increase >50% as the endpoint of the study, showed a statistically significant different graft survival in the two groups (log-rank test = 5.489; P = 0.01). The univariate relative risk of deterioration of graft function among patients with higher RI was 3.77. Proteinuria and recipient age increased the risk as well. CONCLUSIONS: Our data seem to suggest that early determination of RI can help predict long-term graft function in kidney transplant recipients.     

寡克隆区带及IgG指数在多发性硬化中的临床意义

目的研究寡克隆区带（OCB）和IgG指数在多发性硬化（MS）中的临床意义。方法收集MS患者54例和其他神经系统疾病（OND）患者271例,包括中枢神经系统感染性疾病62例及非感染性疾病209例的脑脊液和血清标本,分别进行OCB检测（聚丙烯酰胺凝胶电泳）和IgG指数的计算（免疫火箭电泳法）。结果MS组OCB阳性率为35.2%;OND组为8.9%,其中感染组为24.2%,非感染组为4.5%。MS与OND组整体比较OCB阳性率有显著性差异（P〈0.05）,但与感染组相比无显著性差异（P〉0.05）。MS组IgG指数阳性率为83.3%,OND组为78.2%（P〉0.05）。结论OCB对MS有一定的辅助诊断价值,但需除外CNS感染性疾病。IgG指数阳性可作为参考。     

不同分级肝硬化患者血清甲状腺素水平的意义

目的探讨肝硬化患者血清中甲状腺素水平的变化与肝硬化病变程度及其临床实验室检查之间的相关性。方法用放免法测定肝硬化患者血清FT3、FT4、PC-Ⅲ、Ⅳ-C、LN及HA，并按Child—Pugh方法将肝功能分为A、B、C三级。结果随着肝硬化病变程度的加重，血清肝纤维化指标逐渐增高，甲状腺素呈下降趋势，同时血清甲状腺素水平与肝硬化的低蛋白血症、腹水及凝血酶原时间密切相关。结论肝硬化患者体内存在不同程度的甲状腺素水平紊乱，紊乱程度与肝功能受损程度有明显相关性，联合检测血清FT3、FT4、PC-Ⅲ、Ⅳ—C、LN及HA对估计肝硬化病变程度及判断预后有十分重要的临床价值。     

脑电双频指数指导老年病人异丙酚麻醉诱导用量

[目的]通过监测老年病人麻醉诱导时脑电双频指数(BIS)的变化,探讨既能维持足够麻醉深度又能避免严重低血压的异丙酚诱导用量。[方法]40例ASA II～I级的老年病人(65～85岁),随机分成两组。A组静脉注射异丙酚1.6 mg/kg;B组静脉注射异丙酚,其用量是使BIS下降到40～50时的用量。两组均复合维库溴铵0.1 mg/kg和瑞芬太尼1ug/kg诱导后行气管插管分别记录基础值、插管前、插管后1 min、5 min和10 min时的收缩压(SBP)、舒张压(DBP)、平均动脉压(MAP)、心率(HR),同时记录诱导异丙酚用药量和BIS的变化。[结果]A组异丙酚诱导用药量(99.7±18.05)mg,平均(1.64±0.7)mg/kg,B组(82.9±12.5)mg,平均(1.35±0.5)mg/kg,差异有统计学意义(P﹤0.05)。A组血压(BP)和BIS比B组明显降低。[结论]老年病人异丙酚麻醉诱导的合适用量为(1.35±0.5)mg/kg;既能维持老年人足够的麻醉深度又能避免严重低血压的发生。     

血液分析仪红细胞指数质控方法的探讨

目的 探讨血液分析仪红细胞指数的质控方法。方法 利用L-J质控空图和某全血质控物提供的有关数据,推理论证红细胞指数[MCV、MCH、MCHC]在控时对其有关测定参数值的新的质控要求。结果 红细胞指数有关测定参数值的质控范围应分别为HGB:(?)±1.7 s,HCT:(?)±1.06 s,RBC:(?)±1.06s。超出此范围判定为失控。结论 执行该质控判定标准可以实现对红细胞指数实施质控的目的。     

踝肱指数异常增高的糖尿病患者心血管病危险因素研究

目的 分析踝肱指数（ABI）增高的糖尿病患者的心血管病危险因素。方法采用多普勒血流探测仪测定解放军第306医院2003--2005年门诊及病房收治的493例2型糖尿病患者的ABI，以ABI〈0．90为低ABI组（n=39），0．90≤ABI≤1．40为正常组（n=353），ABI〉1．40为高ABI组（n=101）；同时对心血管病危险因素进行分析。结果高ABI与正常ABI组比较，腰围、腰臀比、C反应蛋白、尿酸显著增高，吸烟率及高血压合并症发生率显著增加。结论ABI〉1．40的糖尿病患者有更多的动脉硬化危险因素，需要将这些患者与ABI〈0．90的患者同样重视。     

体表面积、体质量指数对老年骨质疏松的影响

目的探讨体表面积（BS）、体质量、体质量指数（BMI）对老年人骨密度（BMD）的影响。方法用双能X线骨密度仪测定1794例老年人腰椎、髋关节的BMD值，并对其与BS等指标进行相关回归分析。结果BS大的老年人其BMD大于BS小者，有显著性差异。在各种指标与BMD的相关性比较中，BS与BMD的相关性最好，其后依次为：体质量、身高、OSTA得分（亚洲人自我骨质疏松筛查工具）、BMI。结论BS比BMI等指标更能反映出人体体型对老年人BMD的影响。     

Intentional mis-reporting of food consumption and its relationship with body mass index and psychological scores in women

BACKGROUND: The reasons for mis-reporting food consumption warrant investigation. OBJECTIVE: To document intention to mis-report food consumption and its associations with psychological measures in women. DESIGN: A total of 184 female volunteers aged 18-65 years, comprising 50 seeking help in primary care to lose weight with a body mass index (BMI) >/=30 kg m(-2) (obese-clinical group) and 134 nurses (nonclinical groups) (BMI <25 kg m(-2), n = 52; BMI 25-29.9 kg m(-2), n = 45; BMI >/=30 kg m(-2), n = 37) were studied. A questionnaire was administered containing three psychological tests (self-esteem, psychological well-being and Stunkard's three-factor eating questionnaire) and new items to address food intake mis-reporting. RESULTS: Overall, 68% of participants declared an inclination to mis-report (64% nonclinical, 78% clinical). Inclination to under-report was 29, 33 and 51% in the three nonclinical groups; and 46% among the obese clinical patients. Among the same groups, inclination to over-report were 39, 29, 11 and 32%. After adjusting for social deprivation and BMI, women inclined to mis-report had higher hunger (P = 0.008) and disinhibition (P = 0.005) scores than those intending to report accurately. These variables were associated with current dieting, frequency of dieting, self-reported bingeing and dissatisfaction with body weight. CONCLUSIONS: These findings indicate that intentional under-reporting and over-reporting of food consumption are common in women of all BMI categories and are associated with eating behaviour. Current dieting, frequency of dieting in the past, self-reported bingeing and dissatisfaction with body weight seem to mediate this relationship.
