Supportive employment for individuals with chronic schizophrenia: the case for a National Health Service community-based sheltered workshop

A pilot project was established from 1992 to 1994 to provide people with chronic schizophrenia living in Dundee, Scotland, with a National Health Service sheltered workshop that would be fully integrated into the local business community. Of the 43 clients who attended the sheltered workshop, 38 agreed to take part in the project. Typical attenders were single, middle-aged men with schizophrenia. Twenty-five per cent had spent more than two years in hospital; 75% had been unemployed for more than five years. The clients' use of National Health Service day facilities more than halved while attending the workshop. Their hospital readmission rates were low (16%) compared with the local readmission rates for people with schizophrenia in Dundee (86%). A training approach based on the general principles of social skills training contributed to positive vocational outcomes for one-third of the workshop clients. The findings suggest that the onus of responsibility for providing work for many individuals with schizophrenia remains with the National Health Service, and in particular, occupational therapy. Occupational therapy staff must assess their clients effectively and provide quality training leading to opportunities for paid employment. These results have implications for the training of occupational therapy staff and also for the staffing structure in sheltered workshops. Copyright © 1997 Whurr Publishers Ltd.     

肝癌术后监测血清AFP的临床意义(附70例报告)

为探讨肝癌术后监测血清甲胎蛋白(AFP)的临床意义，回顾性分析1996年2月至2002年3月间肝癌根治切除术后定期监测发现血清AFP阳性的70例患者AFP升高与肿瘤残留、复发或转移的关系。肝癌术后血清AFP升高可见于肝癌的残留或早期转移、肝癌的复发或转移、肝癌的再发以及晚期肝硬变4种情况。对肝癌患者术后定期作AFP检查，有助于检出AFP阳性肝癌患者的肿瘤残留及亚临床期复发转移，不仅适用于术前AFP阳性，而且适用于术前AFP阴性的肝癌患者。肝癌患者术后AFP下降，但不能降至正常，可能与晚期肝硬变肝脏内干细胞-卵圆形细胞代偿性增生有关。     

Factors associated with recovery and recurrence of depression in older people: A prospective study

The Liverpool Continuing Health in the Community Study has followed up 1070 elderly community subjects over 6 years. In the first year 123 subjects had case-level depression. Three years later 49 (39.8%) of the previously depressed were recovered, 33 (26.8%) were depressed, 16 (13%) were not available for interview and 25 (20.3%) were dead. This study looks at factors associated with the 3-year outcome of patients who were depressed at year 0. Two outcome groups that were compared were a recovered depression group and a recurrent/persistent depression group. The factors that were significantly associated with a recurrence of depression (or persistent depression) at year 3 were bereavement of a close figure in the 6 months before interview, loneliness and life dissatisfaction at year 3. A variety of traditional risk factors for depression (including age, marital status, physical ill-health and incapacity) failed to attain significance in predicting recurrent or persistent depression. When combined, both recovered and recurrently depressed groups at year 3 had significantly higher levels of pain and a higher number of serious upsets in the past 6 months and 6 weeks compared to a compared to a control group. The depressed at year 0 were more likely to have entered more dependent forms of accommodation by year 3.     

Do discrepancies in interpersonal perception predict relapse?: A comparison of remitted depressed patients and collaterals

In an effort to examine whether disturbed interpersonal relationships are associated with relapse in depression, discrepancies in self-ratings provided by formerly depressed patients and their collateral informants were compared. Thirty-eight remitted depressed patients and their collateral informants were asked to monitor moods, life events, and stress levels on a bimonthly basis for a 1-year period. It was hypothesized that patient/collateral dyads displaying a greater discrepancy in interpersonal perception would have a higher risk of relapse than dyads who showed more agreement in their ratings. Results indicated that while discrepancies in the perceptions of patients' life events were associated with the duration of a relapse once it occurred, discrepancies were generally not related to the emergence of new episodes of depressive disorder. The implications of these findings for models seeking to integrate cognitive and interpersonal models of depression, through the study of environmentally determined and personally appraised adversity, is discussed.This research was supported by grants to the first and third authors from the Canadian Psychiatric Research Foundation and the Laidlaw Foundation.     

Outcome of surgery in patients with hematological malignancies: A 12-year retrospective analysis

Background: Surgical intervention in patients with malignant hematological disorders is a major undertaking due to the expected risks of bleeding, infection and poor wound healing. Methods and materials: A retrospective study of patients treated at the Riyadh Armed Forces Hospital, Saudi Arabia between January 1991 and December 2002 was conducted. The results of patients with acute leukemia and lymphoma who underwent surgical procedures (study group) were compared with those of a control group composed of patients with the same spectrum of disorders treated over the same period of time and given the same treatment protocols but never required any surgery. Results: No single death occurred intraoperatively or in the immediate postoperative period due to surgical therapy per se. However, follow up of both groups of patients revealed a shorter long‐term survival and higher rates of relapse and severe invasive infections in the surgical group compared to the control group of patients. The mean survival for the study group was 1871 ± 307 days versus 3094 ± 279 days for the control group of patients (P = 0.0027). Thirty (75%) study patients suffered relapses of their malignant hematological disorders versus 23 (37.1%) control patients. Forty‐five relapses were encountered in the study group of patients (1.5 relapses per relapsed patient) versus 26 relapses in the control group (1.13 relapses per relapsed patient). Various infections occurred in 37 (92.5%) study patients and 32 (51.6%) control patients. Recurrent infections developed in 30 (75%) study patients and 22 (35.5%) control patients (P = 0.00008). Infections causing tissue invasion were encountered in 29 (72.5%) study patients and 22 (35.5%) control patients. Conclusion: Even major surgical procedures can be performed in patients with leukemia or lymphoma provided enough preparatory measures are made to minimize bleeding and infectious complications. Surgery may, however, be associated with long‐term complications such as a high incidence of relapse of the primary malignant hematological disorder and an increased rate of severe and invasive infections.     

Aripiprazole blocks reinstatement of cocaine seeking in an animal model of relapse.

BACKGROUND: Aripiprazole (Abilify) is an atypical antipsychotic drug primarily characterized by partial agonist activity at dopamine (DA) D2 receptors and low side effects. Based on pharmacologic properties that include a stabilization of mesocorticolimbic DA activity, a pathway implicated in addiction, aripiprazole was tested for its ability to prevent relapse to cocaine seeking in rats. METHODS: We assessed the dose-dependent effects of aripiprazole on conditioned cue-induced and cocaine-primed reinstatement of drug-seeking behavior following chronic intravenous cocaine self-administration in an animal model of relapse. RESULTS: Aripiprazole potently and dose-dependently attenuated responding on the previously cocaine-paired lever during both reinstatement conditions, with slightly greater efficacy at reducing conditioned-cued reinstatement. Aripiprazole was effective at doses that failed to alter cocaine self-administration, food self-administration, reinstatement of food-seeking behavior, or basal locomotor activity, suggesting selective effects of aripiprazole on motivated drug-seeking behavior. CONCLUSIONS: These results in a relapse model show that aripiprazole can block cocaine seeking without affecting other behaviors. The D2 partial agonist properties of aripiprazole likely account for the blockade of reinstatement of cocaine-seeking behavior. Given its established efficacy and tolerability as a treatment for psychosis, aripiprazole may be an excellent therapeutic choice for reducing craving and preventing relapse in people with cocaine dependency.     

Optimising Hormone Therapy in Advanced Disease

Although most prostate cancer (PCa) patients nowadays are diagnosed at an early stage of disease, unfortunately still a significant number of patients will develop advanced PCa or will be diagnosed at an advanced (or metastatic) stage of disease. The group of patients showing the highest increase in incidence are those with rising prostate specific antigen (PSA) after radical therapy.In the last quarter of 2004, a Medline search has been performed targeting publications on patients diagnosed with advanced PCa, as well as with PSA relapse after previous radical therapy. This review aims at providing guidance to optimise hormone therapy in those selected groups of patients by addressing three pivotal questions; (i) who should receive hormonal treatment, (ii) what type of hormonal therapy should the patient be offered and (iii) what is the best timing of starting hormonal treatment.In patients relapsing after radical therapy, the PSA doubling time (PSA DT) has become a critical instrument to distinguish patients to have innocuous PSA evolution from patients at high risk for disease progression. A PSA DT of 3 months seems to be the cut-off point for identifying patients at risk. Therefore patients with a PSA DT of less than 3 months should be advised to initiate hormonal therapy. Antiandrogen monotherapy may be considered in this setting as it has been shown to delay progression; however, significant survival data are not yet available. Whether luteinising hormone releasing hormone (LHRH) agonists should be given continuously or intermittently (IHT) remains subject of debate.Surgical castration has been the standard of care in patients diagnosed with advanced PCa. Currently, LHRH agonists have become the preferred way of suppressing testosterone.Combination of an antiandrogen and a LHRH agonist (CAB) shows a modest benefit over LHRH agonist monotherapy. As CAB leads to increased side effects and costs, LHRH agonist monotherapy is preferred in the majority of patients.Conflicting data have been published concerning the optimal timing of LHRH agonist therapy. So it is not clear whether LHRH agonist therapy should be started immediately or deferred until appearance of symptoms. When initiating continuous hormone therapy, patients should be carefully monitored for the risk of long term androgen deprivation (anaemia, osteopenia and osteoporosis).     

Conservatively Treated Breast Cancer: Outcome by Histologic Subtype

Abstract: Between 1970 and 1990, 1,008 patients with early-stage breast cancer were treated by conservative surgery without axillary dissection followed by radiation therapy to the intact breast in the Department of Therapeutic Radiology at Yale-New Haven Hospital. The patient population, broken down by histologic subtype, was as follows: 761 patients presented with infiltrating ductal carcinoma, 70 patients with pure intraductal, 38 intraductal with focal invasion, 54 infiltrating lobular, 21 tubular, 17 medullary, 16 mucinous, and 29 with other various histologic subtypes. Patients were followed on a regular basis by the referring physicians and radiation oncologists. Diagnostic studies for distant metastases were performed as clinically indicated. Annual mammography was a routine component of the follow-up program. As of 3/96, with a median follow-up of 10.5 years, 83 patients developed an ipsilateral breast tumor recurrence, and 109 patients developed distant metastases resulting in an overall 10-year breast recurrence-free rate of 84%, and a 10-year distant metastasis-free rate of 78%. There were significant differences in clinical stage, pathological nodal involvement, and administration of systemic therapy between various histologic subtypes. As expected, those patients with histologies of low metastatic potential (such as intraductal, tubular, and mucinous) had significantly superior distant recurrence-free survival rates. With respect to breast relapse rates, there were no statistically significant differences in the 5- and 10-year breast recurrence-free rates between any of the histologic subtypes. Patients with intraductal carcinoma with or without focal invasion had similar breast relapse rates as those with other histologic subtypes. Patients with lobular carcinoma in situ as a histologic component also had a similar overall breast relapse-free recurrence rate. In conclusion, long-term follow-up of conservatively treated breast cancer patients demonstrates no significant differences in ipsilateral breast tumor recurrence rates between various histologic subtypes. There are no histologies which had a statistically significantly higher breast-relapse rate than infiltrating ductal carcinomas and therefore no primary histologic subtype represents a relative contraindication to breast conservation therapy.     

Relapse rate and outcome of ANCA-associated small vessel vasculitis after transplantation.

BACKGROUND: Anti-neutrophil cytoplasm antibody-associated systemic vasculitis (AASV) is a rare disease and frequently leads to end-stage renal disease (ESRD). Potentially fatal disease activity can develop after the onset of ESRD or in transplanted patients despite the immunosuppressive effects of uraemia and rejection prophylaxis, respectively, leading to concern that such patients may have greater morbidity and mortality. METHODS: To assess the outcome of patients with AASV following kidney transplantation, a retrospective analysis was performed of nine patients with AASV at our unit who received renal transplants between 1987 and 2000. The renal survival of the patients was compared with a control population who received kidney transplants over the same period for causes other than AASV and diabetes mellitus. RESULTS: Nine patients with the diagnosis of AASV (five patients with Wegener's granulomatosis and four with microscopic polyangiitis) received eight cadaveric grafts and one live-related graft after a mean of 44 months from the start of dialysis. These patients had a mean age of 49.2 years at time of transplantation and they were followed up for a mean of 62 months post-transplantation. Two patients with Wegener's granulomatosis suffered a vasculitic relapse affecting the upper respiratory tract at 40 and 50 months post-transplantation, corresponding to a relapse rate of 0.04 per patient per year. The renal transplant function of vasculitis patients compared with 18 non-diabetic control patients who were transplanted at the same time was better in the vasculitis patients at some time points (P=0.054 at 6 months). CONCLUSIONS: There is a substantial relapse rate in the AASV population, especially affecting the upper respiratory tract and with increasing duration of follow-up. Nonetheless, renal transplantation is a good option for the treatment of vasculitis patients and their outcome compares favourably with that of other non-diabetic patients following transplantation.     

156例脑梗塞的临床分析

本文报道脑梗塞患者156例,就其发病情况,诱发因素,临床特点,治疗及预防进行了分析讨论。脑梗塞的发病高于脑出血,高血压动脉硬化是发生脑梗塞的主要危险因素。积极预防和治疗高血压有极其重要的意义。脑梗塞的治疗应根据脑水肿的情况进行,不宜普遍首先应用扩血管治疗。本病复发率高,反复发作可引起广泛性脑部损害,其病死率、病残率明显高于首次发病。小剂量阿斯匹林等药物应用对预防复发可能有一定作用。
