Anthropological perspectives on alcohol and drugs at the turn of the new millennium.

This introduction to the collection provides our thoughts on where alcohol and drug studies in anthropology are going as we enter the new millennium. After commenting briefly on each of the papers that comprise the rest of the volume, we discuss what we see as the most important and exciting issues in the future and give our views on what alcohol and drug studies can offer to medical anthropology, anthropology writ large, interdisciplinary and multidisciplinary research, and the realm of public policy and practical affairs. We call for a continued study by anthropologists of the whole array of pharmacologically active substances used by humans in different parts of the world, whether or not such studies are situated within medical anthropology. We note that many of these substances have received little attention from anthropologists to date, quite strikingly so in the cases of substances such as marijuana and methamphetamines. We emphasize that most scholars working in the anthropology of alcohol and drugs are concerned with the application of their findings to social problems, and we note that this has been especially true of research on alcoholic beverages and injection drugs. This leads us to a discussion of anthropology's involvement in public health intervention and policy work in a variety of settings. Such involvement is shown to have informed anthropological theory (notably political economic approaches) and to have enriched the methodological toolkits and forms of data analysis anthropologists use. Perhaps more importantly, we argue that such multidisciplinary involvement in applied work is most likely to eventuate in theoretical progress in alcohol and drug studies, since theory in the social sciences is not bound to singular disciplinary approaches. Thus we advocate for a "hybrid vigor" in this specialty area in the years ahead.

Erdheim-chester disease.

Erdheim-Chester disease (ECD) is a rare histiocytic infiltrative disease, characterized by long bone sclerosis. We describe two confirmed cases of ECD, both of which demonstrate non-malignant retroperitoneal and peri-renal infiltration causing dilatation of the upper renal tracts. The cases are illustrated with contrast studies, computed tomography (CT) and magnetic resonance imaging (MRI). Typical sclerosis of the long bones was apparent on radiography. Both cases have been treated conservatively to date.A brief review of the literature regarding the manifestations of ECD is included. In cases of non-malignant retroperitoneal infiltration, ECD should be considered as a diagnosis and radiographs of the long bones performed.

Influence of patient posture on oxygen saturation during fibre-optic bronchoscopy.

This study was designed to investigate the effect of posture on oxygen saturation during fibre-optic bronchoscopy (FOB). Thirty-eight consecutive patients requiring diagnostic FOB were randomized into two groups according to the initial posture in which the FOB was performed. In group 1 (20 patients), FOB was commenced supine, and in group 2 (18 patients) in a semi-recumbent position (45 degrees from horizontal). Sedation with midazolam was titrated according to clinical response. All patients received atropine 0.6 mg intravenously and topical lignocaine. Observations of peak, trough and plateau oxygen saturation and pulse rate were recorded during six study periods, each lasting 3 min. Periods 1 and 2 were pre- and post-sedation without supplemental oxygen, respectively. The bronchoscope was then inserted into the distal end of the trachea and observations taken during periods 3 and 4 (no supplemental oxygen) and periods 5 and 6 (2 l oxygen by nasal cannulae). In group 1, posture was changed from supine to semi-recumbent from periods 3-4 and reversed in periods 5 and 6. In group 2, posture changes were in reverse sequence. Patients with initial oxygen saturation of less than 90% or showing a fall below 85% during FOB were excluded. Five patients from each group were withdrawn because of hypoxia. In both groups, oxygen saturation fell significantly (P<0.001) following sedation. There was no significant change in saturation (peak, trough or plateau) with change in posture from supine to semi-recumbency (group 1) or the reverse (group 2). These correspond to periods 3-4 and 5 6 in both groups. Supplemental oxygen was associated with a significant rise in oxygen saturation in both postures, attaining levels close to presedation levels.

A method to assess predominant energies of exposure in a nuclear research centre--Saclay (France).

A study of dosimetric errors is under way within an international collaborative study of cancer risk among workers in the nuclear industry. The objective is to quantify errors in the estimated photon doses to individual organs used for cancer risk estimation. One source of errors is the response of old dosemeters in workplace exposure conditions. As these conditions are not well known, the International Study must rely on expert estimations. This paper describes a method to assess the proportion of the dose from photons in three energy ranges (< 100, 100-300, > or = 300 keV) using the responses under filters of a multi-element dosemeter. The method was tested on experimental and simulated data and provides a good estimate of the proportion of dose from photons below 100 keV, the most critical for dosemeter response. It was applied to personnel readings in one facility, confirming the experts' estimation. Beyond the International Study, the method has implication for the monitoring and protection of workers.

Public release of information on quality of care: how are health services and the public expected to respond?

Public disclosure of the comparative performance of health care providers has been proposed as one mechanism of improving the quality of care. Performance data have been made public in the USA for over a decade and the provision of comparative information about quality of care is a central feature of current UK government health policy. The balance between the advantages and risks of pursuing such a policy in publicly funded health service is largely unknown. Advocates of public disclosure cite the role that comparative data can play in ensuring accountability, shifting the ownership of information (and therefore power) from professionals to service users and encouraging improvements in the processes and outcomes of care. However, these expectations are not necessarily realistic. There is some evidence that the public make little use of comparative data and there is a risk that public release may result in a loss of confidence in the health system and demoralisation of health service staff. In addition, there is a legitimate doubt that any early impact of disclosure will not be sustained and that the outcomes will not justify the necessary expenditure. In conclusion, we suggest that the theoretical benefits of promoting public disclosure as voiced by advocates of the policy may not be realised in practice.

Predictive value of impaired evacuation at proctography in diagnosing anismus.

OBJECTIVE: We aimed to determine the positive predictive value of impaired evacuation during evacuation proctography for the subsequent diagnosis of anismus. SUBJECTS AND METHODS: Thirty-one adults with signs of impaired evacuation (defined as the inability to evacuate two thirds of a 120 mL contrast enema within 30 sec) during evacuation proctography underwent subsequent anorectal physiologic testing for anismus. A physiologic diagnosis of anismus was based on a typical clinical history of the condition combined with impaired rectal balloon expulsion or abnormal surface electromyogram. RESULTS: Twenty-eight (90%) of the 31 patients with impaired proctographic evacuation were found to have anismus at subsequent physiologic testing. Among the 28 were all 10 patients who evacuated no contrast medium and all 11 patients with inadequate pelvic floor descent, giving evacuation proctography a positive predictive value of 90% for the diagnosis of anismus. A prominent puborectal impression was seen in only three subjects during proctography, one of whom subsequently showed no physiologic sign of anismus. CONCLUSION: Impaired evacuation during evacuation proctography is highly predictive for diagnosis of anismus.

The combination of zidovudine and interferon alpha-2B in the treatment of adult T-cell leukemia/lymphoma.

Adult T-cell leukemia/lymphoma (ATL) is frequently a very aggressive malignancy with a poor survival despite aggressive multiagent chemotherapy. The combination of the antiretroviral drug zidovudine (AZT) and interferon alpha (IFNalpha) has been reported to induce remissions in patients with ATL. The purpose of this study was to evaluate the clinical response and toxicity following administration of a combination of IFNalpha-2b and AZT in patients with human T-cell lymphotropic virus type I (HTLV-I)-associated ATL. Eighteen patients with ATL (chronic. crisis, acute or lymphoma type) were treated with the combination of AZT (50 - 200 mg orally 5 times a day) and IFNalpha-2b (2.5 - 10 million units subcutaneously daily). Three patients had objective responses lasting more than one month. One patient had a clinical complete remission, lasting 21.6 months and two patients had partial remissions lasting 3.7 and 26.5 months. Six patients were not considered evaluable for response due to short and/or interrupted periods of treatment. Seventeen patients have died with a median survival time after initiation of therapy of 6 months. Neutropenia and thrombocytopenia were the dose limiting toxicities. In conclusion, the response rate in this study was lower than noted in the two previous published series. This may be due to the amount and type of prior treatment our patients had received.

Systematic reviews of the effectiveness of day care for people with severe mental disorders: (1) acute day hospital versus admission; (2) vocational rehabilitation; (3) day hospital versus outpatient care.

UNLABELLED: ***ACUTE DAY HOSPITAL VERSUS ADMISSION FOR ACUTE PSYCHIATRIC DISORDERS*** BACKGROUND: Inpatient treatment is an expensive way of caring for people with acute psychiatric disorders. It has been proposed that many of those currently treated as inpatients could be cared for in acute psychiatric day hospitals. OBJECTIVE: The aim of this review was to assess the effectiveness and feasibility of day hospital versus inpatient care for people with acute psychiatric disorders. METHODS - STUDY SELECTION: Eligible studies were randomised controlled trials of day hospital versus inpatient care for people with acute psychiatric disorders. Studies were excluded if they were primarily concerned with elderly people, children, or patients with a diagnosis of organic brain disease or substance abuse. METHODS - DATA SOURCES: We searched the Cochrane Controlled Trials Register, MEDLINE, EMBASE, CINAHL, PsycLIT, and the reference lists of articles. Researchers were approached to identify unpublished studies. Trialists were asked to provide individual patient data. METHODS - DATA EXTRACTION: Data were extracted independently by two reviewers and cross-checked. METHODS - DATA SYNTHESIS: Relative risk (RR) and 95% confidence intervals (CIs) were calculated for dichotomous data. Weighted or standardised means were calculated for continuous data. Day hospital trials tend to present similar outcomes in slightly different formats, making it difficult to synthesise the data. Individual patient data were therefore sought so that outcomes could be re-analysed using a common format. RESULTS: Nine trials met the inclusion criteria (involving 1568 randomised patients and 2268 assessed for suitability of day hospital treatment). Individual patient data were obtained for four trials (involving 594 people). A sensitivity analysis of combined data suggested that day hospital treatment was feasible for at worst 23.2% (n = 2268; 95% CI, 21.2 to 25.2) and at best 37.5% (n = 1768; 95% CI, 35.2 to 39.8) of those currently admitted to inpatient care. Individual patient data from three trials showed no difference in the number of days in hospital (combining day hospital days and inpatient days) between day hospital patients and controls (n = 465; weighted mean difference (WMD) = -0.38 days/ month; 95% CI, -1.32 to 0.55). However, compared with controls, patients randomised to day hospital care spent significantly more days in day hospital care (n = 265; WMD = 2.34 days/month; 95% CI, 1.97 to 2.70) and significantly fewer days in inpatient care (n = 265; WMD = -2.75 days/month; 95% CI, -3.63 to -1.87). There was no difference between readmission rates for day hospital and control patients (n = 667; RR = 0.91; 95% CI, 0.72 to 1.15). Individual patient data from three trials showed a significant time-treatment interaction, indicating a more rapid improvement in mental state (n = 407; c2 = 9.66; p = 0.002), but not social functioning (n = 295; c2 = 0.006; p = 0.941) amongst day hospital patients. Four of five trials demonstrated that day hospital care was cheaper than inpatient care (with overall cost reductions ranging from 20.9% to 36.9%). CONCLUSIONS: Acute day hospitals are an attractive option in situations where demand for inpatient care is high and facilities exist that are suitable for conversion. They are a less attractive option when demand for inpatient care is low and where effective alternatives already exist. The interpretation of day hospital research would be enhanced if future trials made use of the common set of outcome measures used in this review. It is important to examine how acute day hospital care can be most effectively integrated into a modern community-based psychiatric service. ***VOCATIONAL REHABILITATION FOR PEOPLE WITH SEVERE MENTAL DISORDERS*** BACKGROUND: People who are disabled by severe mental disorders experience high rates of unemployment, but most want to work. Prevocational training (PVT) is the traditional approach to helping such people to return to work. PVT assumes that a period of preparation is required before those with a severe mental disorder can enter into competitive employment. Supported Employment (SEm) is a new approach that places clients in competitive employment without extended preparation. Both PVT and SEm are widely practised, but it is unclear which is the most effective. OBJECTIVES: The overall objective of this review was to assess the effectiveness of PVT and SEm relative to each other and to standard care (in hospital or the community) for people with severe mental disorders. In addition, the review examined the effectiveness of: (1) special types of PVT ("clubhouse" model) and SEm (individual placement and support model); and (2) modifications for enhancing PVT (e.g. payment or psychological interventions). METHODS - STUDY SELECTION: Eligible studies were randomised controlled trials (RCTs) examining the effectiveness of vocational rehabilitation approaches (PVT and SEm or modifications) for people of working age and suffering from a severe mental disorder. METHODS - DATA SOURCES: Relevant trials were identified from searches of the Cochrane Schizophrenia Group's specialised register, MEDLINE, EMBASE, CINAHL and PsycLIT, and the reference lists of all identified studies and review articles. Researchers who were active in the field were approached in order to identify unpublished studies. METHODS - DATA EXTRACTION: All data were extracted independently by two reviewers and cross-checked. Continuous data were excluded if they were collected by using an unpublished scale or were based on a subset of items from a scale. METHODS - DATA SYNTHESIS: For all comparisons, the primary outcome was the number of clients who were in competitive employment at various time points. Secondary outcomes were: other employment outcomes, clinical outcome and costs. The relative risk (RR) and number-needed-to-treat (NNT) were calculated for the relevant categorical outcomes. Continuous data were either presented as in the original trial reports or, where possible, combined across trials as a standardised mean difference score. RESULTS: Eighteen RCTs of reasonable quality were identified: PVT versus hospital controls, three RCTs, n = 172; PVT versus community controls, five RCTs, n = 1204; modified PVT, four RCTs, n = 423; SEm versus community controls, one RCT, n = 256; and SEm versus PVT, five RCTs, n = 491). The main finding was that, on the primary outcome (number in competitive employment), SEm was significantly more effective than PVT at all time points (e.g. at 12 months, SEm 34% employed, PVT 12% employed; RR of not being in competitive employment = 0.76, 95% confidence interval 0.69 to 0.84, NNT = 4.5). Clients in SEm also earned more and worked more hours per month than those in PVT. CONCLUSIONS: The main finding was that SEm was more effective than PVT for patients suffering from a severe mental disorder who wanted to work. There was no evidence that PVT was more effective than standard community care or hospital care. The implication of these findings is that people suffering from mental disorders who want to work should be offered the option of SEm. Commissioning agencies would be justified in encouraging vocational rehabilitation (VR) providers to develop more SEm schemes. From a research perspective, the cost-effectiveness of SEm should be examined in larger multicentre trials, both within and outside the USA. There is a case for countries outside the USA to survey their existing VR services to determine the extent to which the most effective interventions are being offered. ***DAY HOSPITAL VERSUS OUTPATIENT CARE FOR PATIENTS WITH PSYCHIATRIC DISORDERS*** BACKGROUND: This review considers the use of day hospitals as an alternative to outpatient care. Two typesof day hospital provision are covered: "day treatment programmes" and "day care centres". Day treatment programmes are day hospitals that are used to enhance the treatment of patients with anxiety or depressive disorders who have failed to respond to outpatient care. Day care centres are day hospitals that offer structured support to patients with long-term severe mental disorders who would otherwise be treated in an outpatient clinic. OBJECTIVES: There were two objectives: first, to assess the effectiveness of day treatment programmes versus outpatient care for people with non-psychotic disorders; and, secondly, to assess the effectiveness of day care centres versus outpatient care for people with severe long-term disorders. METHODS - STUDY SELECTION: Eligible studies were randomised controlled trials comparing day hospital care (either a day treatment programme or a day care centre) with outpatient care. Studies were ineligible if they were largely restricted to patients who were aged under 18 or over 65 years or who had a primary diagnosis of substance abuse or organic brain disorder. METHODS - DATA SOURCES: Relevant trials were identified from searches of the Cochrane Controlled Trials Register, MEDLINE, EMBASE, CINAHL, PsycLIT, and the reference lists of all identified studies and review articles. Researchers were approached to identify unpublished studies. Trialists were asked to provide individual patient data. METHODS - DATA EXTRACTION: All data were extracted independently by two reviewers and cross-checked. METHODS - DATA SYNTHESIS: Relative risks and 95% confidence intervals were calculated for dichotomous data. Standardised mean differences were calculated for continuous data. RESULTS: There was evidence from two of the five trials identified suggesting that day treatment programmes were superior to continuing outpatient care in terms of improving psychiatric symptoms. There was no evidence to suggest that day treatment programmes were better or worse than outpatient care on any other clinical or social outcome variable or on costs. (ABSTRACT TRUNCATED)

Strain and sex differences in the morphology of the medial preoptic nucleus of mice.

The medial preoptic nucleus (MPO), which is involved in sexual and maternal behaviors, contains neuronal clusters that have been described as being sexually dimorphic in size and neuropeptide content in a variety of species. A subnucleus in DBA/2J (D2) inbred mice, called the pars compacta of the MPO (MPOpc), is absent in C57BL/6J (B6) inbred mice (Robinson et al. [1985] J. Neurogenet. 2:381-388). We report here on experiments that further characterize strain and sex differences in medial preoptic morphology in D2 and B6 inbred mice. A prominent MPOpc, located within the caudal part of the MPO and dorsal to the suprachiasmatic nucleus, was present in both male and female D2 animals but was absent from B6 animals. MPOpc neurons were darkly stained for Nissl substance and larger than neurons in the surrounding MPO. In D2 brains, galanin-immunoreactive (-ir), oxytocin-ir, vasopressin-ir, and NADPH diaphorase-positive neurons were concentrated within the MPOpc. Fewer similar neurons in the comparable region of the MPO of B6 mice suggests that the absence of the MPOpc is due to absence of these neurons rather than a less compact organization. In D2 animals, the density of galanin-ir neurons in the MPOpc was sexually dimorphic, with higher numbers of galanin-ir neurons in females. Strain differences in galanin-ir, oxytocin-ir, vasopressin-ir, and NADPH diaphorase staining appeared to be limited to the MPOpc. Cholecystokinin-immunoreactive neurons, which have been reported to be numerous in the sexually dimorphic central subdivision of the MPO of rats, were sparse in the MPO of D2 and B6 mice. Confirmation of the MPOpc as an accessory magnocellular neurosecretory nucleus was obtained by finding labeling of MPOpc neurons after injection of DiI into the posterior pituitary.

Size reduction of small bowels from adult cadaveric donors to alleviate the scarcity of pediatric size-matched organs: an anatomical and feasibility study.

BACKGROUND: Small bowel transplantation in children weighing less than 10 kg is hindered by the lack of size-matched donors. The ability to create reduced size small bowel grafts from adult cadaveric donors suitable for use in young children has been studied. METHODS: Volumetric assessment of computed tomography scans were used to evaluate abdominal cavity and small bowel volumes in children. Small bowels were retrieved from adult cadaveric donors and reduced in size. RESULTS: Computed tomography studies of the abdominal cavity showed that the mean volume available for a small bowel graft was 260 ml in children less than 5 kg (n = 5) and 460 ml in children weighing 5-10 kg (n = 5). Fifteen small bowels were successfully reduced to provide an ileal graft of one meter while keeping the whole length of the superior mesenteric artery and vein after their dissection in the proximal part of the mesentery. The mean volume of the grafts created was 270 ml in seven thin patients (body mass index [BMI] <25), 390 ml in five preobese patients (25< BMI<30), and 490 ml in three obese patients (BMI>30). Mesenteric transillumination in thin donors allowed safe dissection and complete hemostasis. No diameter reduction was required. Technical modifications permitted the creation of two grafts, one ileal and the other jejunal from a single donor. Volumetric and surgical data show that implantation of up to two meters of ileum from a thin adult weighing up to 80 kg is feasible in children weighing less than 10 kg. CONCLUSION: Size reduction of adult cadaveric small bowels can provide suitable grafts for children of less than 10 kg and could expand the potential pool of donors for these patients.

Case management for people with severe mental disorders.

BACKGROUND: Since the 1960s, in many parts of the world, large psychiatric were closed down and people were treated in outpatient clinics, day centres or community mental health centres. Rising readmission rates suggested that this type of community care may be less effective than anticipated. In the 1970s case management arose as a means of co-ordinating the care of severely mentally ill people in the community. OBJECTIVES: To determine the effects of case management as an approach to caring for severely mentally ill people in the community. Case management was compared against standard care on four main indices: (i) numbers remaining in contact with the psychiatric services; (ii) extent of psychiatric hospital admissions; (iii) clinical and social outcome; and (iv) costs. SEARCH STRATEGY: Electronic searches of CINAHL (1997), the Cochrane Schizophrenia Group's Register of trials (1997), EMBASE (1980-1995), MEDLINE (1966-1995), PsycLIT (1974-1995) and SCISEARCH (1997) were undertaken. References of all identified studies were searched for further trial citations. SELECTION CRITERIA: The inclusion criteria were that studies should be randomised controlled trials that (i) had compared case management to standard community care; and (ii) had involved people with severe mental disorder mainly between the ages of 18-65. Studies of case management were defined as those in which the investigators described the intervention as 'case' or 'care' management rather than 'Assertive Community Treatment' or 'ACT'. DATA COLLECTION AND ANALYSIS: A study was carried out to test the reliability of the inclusion criteria. Categorical data were extracted twice and then cross-checked, any disagreements being resolved by discussion. Odds ratios and the number needed to treat were estimated. Continuous data collected by a measuring instrument was only included if the instrument (i) had been described in a peer-reviewed journal; (ii) was a self-report or had been completed by an independent rater; and (iii) provided a summary score for a broad area of functioning. Normally distributed continuous data were included if means and standard deviations were available. Non-normal data were included if analysed either after transformation or using non-parametric methods. Tests for heterogeneity were conducted. MAIN RESULTS: Case management increased the numbers remaining in contact with services (for case management odds ratio = 0.70; 99%CI 0.50-0. 98; n=1210). Case management approximately doubled the numbers admitted to psychiatric hospital (OR 1.84; 99% CI 1.33-2.57; n=1300). Except for a positive finding on compliance, from one study, case management showed no significant advantages over standard care on any psychiatric or social variable. Cost data did not favour case management but insufficient information was available to permit definitive conclusions. REVIEWER'S CONCLUSIONS: Case management ensures that more people remain in contact with psychiatric services (one extra person remains in contact for every 15 people who receive case management), but it also increases hospital admission rates. Present evidence suggests that case management also increases duration of hospital admissions, but this is not certain. Whilst there is some evidence that case management improves compliance, it does not produce clinically significant improvement in mental state, social functioning, or quality of life. There is no evidence that case management improves outcome on any other clinical or social variables. Present evidence suggests that case management increases health care costs, perhaps substantially, although this is not certain. In summary, therefore, case management is an intervention of questionable value, to the extent that it is doubtful whether it should be offered by community psychiatric services. It is hard to see how policy makers who subscribe to an evidence-based approach can justify retaining case management as 'the cornerstone' of community mental hea

Assertive community treatment for people with severe mental disorders.

BACKGROUND: Assertive Community Treatment (ACT) was developed in the early 1970s as a response to the closing down of psychiatric hospitals. ACT is a team-based approach aiming at keeping ill people in contact with services, reducing hospital admissions and improving outcome, especially social functioning and quality of life. OBJECTIVES: To determine the effectiveness of Assertive Community Treatment (ACT) as an alternative to i. standard community care, ii. traditional hospital-based rehabilitation, and iii. case management. For each of the three comparisons the main outcome indices were i. remaining in contact with the psychiatric services, ii. extent of psychiatric hospital admissions, iii. clinical and social outcome and iv. costs. SEARCH STRATEGY: Electronic searches of CINAHL (1982-1997), the Cochrane Schizophrenia Group's Register of trials (1997), EMBASE (1980-1997), MEDLINE (1966-1997), PsycLIT (1974-1997) and SCISEARCH (1997) were undertaken. References of all identified studies were searched for further trial citations. SELECTION CRITERIA: The inclusion criteria were that studies should i. be randomised controlled trials, ii. have compared ACT to standard community care, hospital-based rehabilitation, or case management and iii. have been carried out on people with severe mental disorder the majority of whom were aged from 18 to 65. Studies of ACT were defined as those in which the investigators described the intervention as "Assertive Community Treatment" or one of its synonyms. Studies of ACT as an alternative to hospital admission, hospital diversion programmes, for those in crisis, were excluded. The reliability of the inclusion criteria were evaluated. DATA COLLECTION AND ANALYSIS: Three types of outcome data were available: i. categorical data, ii. numerical data based on counts of real life events (count data) and iii. numerical data collected by standardised instruments (scale data). Categorical data were extracted twice and then cross-checked. Peto Odds Ratios and the number needed to treat (NNT) were calculated. Numerical count data were extracted twice and cross-checked. Count data could not be combined across studies for technical reasons (the data were skewed) but all relevant observations based on count data were reported in the review. Numerical scale data were subject to a quality assessment. The validity of the quality assessment was itself assessed. Numerical scale data of suitable quality were combined using the standardised mean difference statistic where possible, otherwise the data were reported in the text or 'Other data tables' of the review. MAIN RESULTS: ACT versus standard community care Those receiving ACT were more likely to remain in contact with services than people receiving standard community care (OR 0.51, 99%CI 0.37-0.70). People allocated to ACT were less likely to be admitted to hospital than those receiving standard community care (OR 0.59, 99%CI 0.41-0.85) and spent less time in hospital. In terms of clinical and social outcome, significant and robust differences between ACT and standard community care were found on i. accommodation status, ii. employment and iii. patient satisfaction. There were no differences between ACT and control treatments on mental state or social functioning. ACT invariably reduced the cost of hospital care, but did not have a clear cut advantage over standard care when other costs were taken into account. ACT versus hospital-based rehabilitation services Those receiving ACT were no more likely to remain in contact with services than those receiving hospital-based rehabilitation, but confidence intervals for the odds ratio were wide. People getting ACT were significantly less likely to be admitted to hospital than those receiving hospital-based rehabilitation (OR 0.2, 99%CI 0.09-0.46) and spent less time in hospital. Those allocated to ACT were significantly more likely to be living independently (OR (for not living independently) 0.19, 99%CI 0.06-0. (A

Comparison of either norepinephrine-uptake inhibitors or phentermine combined with serotonergic agents on food intake in rats.

RATIONALE: We have shown previously that the anorectic effects of the catecholamine-releasing agent phentermine (PHEN) and the serotonin (5-HT)-releasing agent dexfenfluramine (DFEN) are greater than additive in rats. In the present study, we examined whether the norepinephrine-uptake inhibitors desmethylimipramine (DMI) and thionisoxetine (TNIX) have additive effects with either DFEN or with the 5-HT-uptake inhibitor fluoxetine (FLX). We also examined whether PHEN interacts with a postsynaptically acting 5-HT agonist. METHODS: Undeprived rats were trained to eat a daily sweet-milk dessert and on test days were systemically administered single or combination drugs and the intakes recorded. RESULTS: Both DMI and TNIX produced dose-related suppressions of food intake. However, by isobolographic analysis, they did not enhance the anorectic actions of either DFEN or FLX. In contrast, confirming and extending our previous work, PHEN had a greater potentiating effect on the anorectic actions of DFEN and FLX than TNIX. Further, the anorectic action of the 5-HT2c receptor agonist TFMPP was enhanced by PHEN. CONCLUSIONS: These and other data are consistent with the idea that 5-HT agents may work "upstream" of critical catecholaminergic synapses in the production of anorexia, and explain the diminished efficacy of norepinephrine-uptake inhibitors relative to PHEN. The implications for clinically useful anorectic agents are discussed briefly.

Rac2 stimulates Akt activation affecting BAD/Bcl-XL expression while mediating survival and actin function in primary mast cells.

Mast cells generated from Rac2-deficient (-/-) mice demonstrated defective actin-based functions, including adhesion, migration, and degranulation. Rac2(-/-) mast cells generated lower numbers and less mast cell colonies in response to growth factors and were deficient in vivo. Rac2(-/-) mast cells demonstrated a significant reduction in growth factor-induced survival, which correlated with the lack of activation of Akt and significant changes in the expression of the Bcl-2 family members BAD and Bcl-XL, in spite of a 3-fold induction of Rac1 protein. These results suggest that Rac2 plays a unique role in multiple cellular functions and describe an essential role for Rac2 in growth factor-dependent survival and expression of BAD/Bcl-XL.

Responses of family caregivers and family members with Alzheimer's disease to an activity kit: an ethnographic study.

This qualitative evaluation research focused on individuals with Alzheimer's disease cared for at home by a family caregiver. It aimed to assess the responses of family caregivers and family members to an activity kit containing 20 therapeutic activities (The BAG or 'Be Active with Games' kit). In-depth interviews with and observations of 21 caregiver/member dyads were analysed according to Spradley's ethnographic method. Responses to The BAG were contingent upon the family member's symptoms, prior experience, and time of day. For some caregivers The BAG was useful in filling time, inspiring additional activities, facilitating connections with the family member, and connecting family members with their past; for others it was an additional burden in an already frenetic life. The BAG engaged some family members with AD while it 'insulted' others. The value of activities for individuals with AD requires more theoretical and methodological exploration.

Molecular mechanism for the Shp-2 tyrosine phosphatase function in promoting growth factor stimulation of Erk activity.

We have previously shown that activation of extracellular signal-regulated kinase (Erk) by epidermal growth factor (EGF) treatment was significantly decreased in mouse fibroblast cells expressing a mutant Shp-2 molecule lacking 65 amino acids in the SH2-N domain, Shp-2(Delta46-110). To address the molecular mechanism for the positive role of Shp-2 in mediating Erk induction, we evaluated the activation of signaling components upstream of Erk in Shp-2 mutant cells. EGF-stimulated Ras, Raf, and Mek activation was significantly attenuated in Shp-2 mutant cells, suggesting that Shp-2 acts to promote Ras activation or to suppress the down-regulation of activated Ras. Biochemical analyses indicate that upon EGF stimulation, Shp-2 is recruited into a multiprotein complex assembled on the Gab1 docking molecule and that Shp-2 seems to exert its biological function by specifically dephosphorylating an unidentified molecule of 90 kDa in the complex. The mutant Shp-2(Delta46-110) molecule failed to participate in the Gab1-organized complex for dephosphorylation of p90, correlating with a defective activation of the Ras-Raf-Mek-Erk cascade in EGF-treated Shp-2 mutant cells. Evidence is also presented that Shp-2 does not appear to modulate the signal relay from EGF receptor to Ras through the Shc, Grb2, and Sos proteins. These results begin to elucidate the mechanism of Shp-2 function downstream of a receptor tyrosine kinase to promote the activation of the Ras-Erk pathway, with potential therapeutic applications in cancer treatment.
