认知矫正治疗对慢性精神分裂症患者临床症状和社会功能的影响

目的:观察认知矫正治疗对慢性精神分裂症患者临床症状和社会功能的改善作用。方法:选择2003-01/08在北京回龙观医院住院的慢性精神分裂症患者104例。均符合CCMD-Ⅲ及DSM-Ⅳ关于精神分裂症诊断标准;年龄25～55岁;病程≥2年;病情稳定,处于迁延、残留或部分缓解状态;药物治疗状况稳定,近期无换药打算;纳入对象或家属同意入组并签署知情同意书。应用随机数字表法将患者分认知矫正治疗组和对照组,每组52例。在相近药物治疗的基础上,认知矫正治疗组以Ann Delahunty和Rodney Morice等制定的神经认知矫正手册(汉化)为治疗工具,在治疗师的指导下进行认知作业练习,内容包括认知灵活性、工作记忆、计划执行功能3大功能模块。对照组予以相同时间的工娱治疗,主要包括有治疗师指导的操作性音乐治疗和舞蹈治疗。治疗前后两组患者分别进行PANSS、住院精神患者社会功能缺陷量表和护士观察量表的评定。结果:实验共纳入慢性精神分裂症患者104例,认知矫正治疗组44例,对照组46例进入结果分析,14例脱落。①治疗前后两组患者PANSS量表总分以及阴性症状量表、复合量表、一般精神病理量表、反应缺乏量表4个分量表的评分均有下降,组内比较差异有显著性意义(t=2.12～4.59,P<0.05);减分情况在两组间差异不明显(P>0.05)。②两组患者的社会功能缺陷量表总分在治疗后均有下降,与治疗前比较,差异有显著性意义(t=3.89,2.04,P<0.05);两组间比较,差异无显著性意义(P>0.05)。认知矫正治疗组治疗后护士观察量表的总病情以及总消极、迟滞2个分量表评分下降,与治疗前比较差异有显著性意义(t=1.49,1.19,2.81,P<0.05);其中迟滞项的减分在两组间比较,差异具有显著性意义(F=4.97,P<0.05)。③社会功能量表的改善与词语流畅性的改善呈正相关(R2=0.36,P<0.05),护士观察量表中总病情与积极两项评分的改善也与言语流畅性测验的改善正相关(R2=0.37,0.34,P<0.05)。结论:认知矫正治疗能在一定程度上改善精神分裂症患者的社会功能,并与部分认知功能的改善相关,但对临床症状无明显改善作用。     

The Novel Electrophysiology of Complex Fractionated Atrial Electrograms: Insight from Noncontact Unipolar Electrograms

Unipolar Characteristics of CFAEs. Background: The noncontact mapping (NCM) system possesses the merit of global endocardial recording for unipolar and activation mapping. Objective: We aimed to evaluate the unipolar electrogram characteristics and activation pattern over the bipolar complex fractionated atrial electrogram (CFAE) sites during atrial fibrillation (AF). Methods: Twenty patients (age 55 ± 11 years old, 15 males) who underwent NCM and ablation of AF (paroxysmal/persistent = 13/7) were included. Both contact bipolar (32–300 Hz) and NCM virtual unipolar electrograms (0.5–300 Hz) were simultaneously recorded along with the activation pattern (total 223 sites, 11 ± 4 sites/patient). A CFAE was defined as a mean bipolar cycle length of ≤ 120 ms with an intervening isoelectric interval of more than 50 ms (Group 1A, n = 63, rapid repetitive CFAEs) or continuous fractionated activity (Group 1B, n = 59, continuous fractionated CFAEs), measured over a 7.2‐second duration. Group 2 consisted of those with a bipolar cycle length of more than 120 ms (n = 101). Results: The Group 1A CFAE sites exhibited a shorter unipolar electrogram cycle length (129 ± 11 vs 164 ± 20 ms, P < 0.001), and higher percentage of an S‐wave predominant pattern (QS or rS wave, 63 ± 13% vs 35 ± 13%, P < 0.001) than the Group 2 non‐CFAE sites. There was a linear correlation between the bipolar and unipolar cycle lengths (P < 0.001, R = 0.87). Most of the Group 1A CFAEs were located over arrhythmogenic pulmonary vein ostia or nonpulmonary vein ectopy with repetitive activations from those ectopies (62%) or the pivot points of the turning wavefronts (21%), whereas the Group 1B CFAEs exhibited a passive activation (44%) or slow conduction (31%). Conclusions: The bipolar repetitive and continuous fractionated CFAEs represented different activation patterns. The former was associated with an S wave predominant unipolar morphology which may represent an important focus for maintaining AF.

Retreatment of hepatitis C patients with pegylated interferon combined with ribavirin in non-responders to interferon plus ribavirin. Is it different in real life?

Background  

More than 50% of hepatitis C viruses (HCV)-infected patients do not respond to the classical Interferon (IFN)/Ribavirin (RBV) combination therapy. The aim of this study was to evaluate the efficacy of retreatment with Peg-Interferon alpha-2b (PEG-IFN alpha-2b) plus RBV, in patients with HCV, genotypes 1 or 3, who were non-responders to the previous standard treatment with IFN/RBV.

Experience of maintenance infliximab therapy for refractory ulcerative colitis from six centres in England

Background  Infliximab is used for treatment of Crohn's disease and, following the Active Ulcerative Colitis Trials (ACT) 1 and 2, it has been used as rescue and maintenance therapy in moderate and severe ulcerative colitis (UC).
Aim  To report on English experience with maintenance infliximab in terms of response and colectomy rates and side-effect profile in UC.
Methods  A retrospective audit conducted by using a web-based questionnaire filled in by 12 gastroenterologists from six English centres.
Results  Of the 38 patients receiving induction with infliximab, 28 (73.6%) maintained an ongoing response (8-weekly infusions 5 mg/kg) for a mean duration of 16.8 months (range 4–59), with 21 (55.3%) being in remission. Three of 38 patients (7.9%) who also responded had a secondary loss of response after an average of 10 months (range 8–13); seven of 38 patients (18.4%) showed no response. The colectomy rate was seven of 38 (18.4%, five non-responders and two with secondary loss of response). Adverse effects occurred in five patients (13.2%). Two discontinued infliximab (alopecia, invasive breast cancer). The three less-severe adverse effects were acute and delayed-type hypersensitivity reactions and one persistent otitis media.
Conclusion  Our experience suggests acceptable response rates, colectomy rates and side-effect profile of maintenance therapy with infliximab in moderate and severe UC.     

Acculturation,collectivist orientation and organisational commitment among Asian nurses working in the US healthcare system

liou s.-r., tsai h.-m. & cheng c.-y. (2013) Journal of Nursing Management  21 , 614–623 Acculturation, collectivist orientation and organisational commitment among Asian nurses working in the US healthcare system Aim To examine the relationships between acculturation, collectivist orientation and organisational commitment among Asian nurses in US hospitals. Background Few studies have explored these three variables together in the same study and examined their statuses and mutual relationship among Asian nurses in Western hospitals. Method The study was a cross-sectional design using snowball sampling. A total of 195 Asian nurses participated. The collectivist orientation scale, organisational commitment questionnaire and acculturation factors were used to collect data. Pearson correlation, anova and regression were used to analyse the data. Results Most participants were female Filipinos with a mean age of 39.92 and a bachelor’s degree and stayed in the USA for 13.35 years. They used and preferred to use both their mother language and English, identified themselves as Oriental or Asian and culturally, viewed themselves as very or mostly Asian. Participants scored high on collectivism and commitment. Collectivism was significantly correlated with commitment but did not mediate acculturation factors and commitment. Conclusion To increase Asian nurses’ commitment, it is important that administrators understand their cultural values and provide them with a cultural competent and sensitive environment. Implications for nursing management Healthcare administrators can increase Asian nurses’ commitment through understanding their needs and attitudes toward their job and organisation.

Prevalence of anti-HCV among Chinese patients with acute and chronic liver disease

To assess whether the hepatitis C virus plays an important role in Chinese patients with acute and chronic liver disease, antibodies to HCV (anti-HCV) were measured by enzyme immunoassay in 67 patients with type A and B acute viral hepatitis, 165 patients with non-A, non-B (NANB) hepatitis, 438 patients with chronic hepatitis, 200 patients with postnecrotic liver cirrhosis, 72 patients with alcoholic liver disease, 55 patients with non-alcoholic fatty liver, 24 patients with toxic and drug-induced hepatitis, and 20 patients with other chronic liver diseases. Anti-HCV was not detected in sera from patients with type A and B acute viral hepatitis, toxic and drug-induced hepatitis, primary biliary cirrhosis, Wilson's disease, or lupoid hepatitis. The anti-HCV prevalence was found to be highest in patients with NANB hepatitis (59% in sporadic and 73.2% in transfusion-associated), 16.4% in non-alcoholic fatty liver, 5.6% in alcoholic liver disease, 6.8% in chronic hepatitis, and 16% in postnecrotic liver cirrhosis. In patients with chronic hepatitis, the anti-HCV prevalence was significantly higher in HBsAg-negative (15/34, 44.1%) than in HBsAg-positive cases (15/404, 3.7%; P less than 0.0001). The results indicate that HCV is a major agent of NANB hepatitis and plays an important role in HBsAg-negative chronic liver disease in Taiwan.
