Abstract
Carvedilol (BM14190) is a new compound with combined properties of nonselective beta-adrenoceptor blockade, devoid of ISA, and precapillary vasodilatation. Its acute hemodynamic effects were studied with invasive technique (dye-dilution using Cardio-Green) in 10 patients taking 25 mg orally and noninvasive (fore-arm plethysmography) in 10 patients taking 25 mg and in 10 patients taking 50 mg orally, all with essential hypertension. Significant reductions of systolic and diastolic blood pressures (p less than 0.05 - 0.001) were observed in all groups. TPR did not change acutely whereas resistance in the fore-arm was reduced by 16% (p less than 0.05). When a comparison with propranolol (80 mgx2) was made in a randomized, double-blind placebo controlled trial comprising 30 patients with essential hypertension, carvedilol acutely reduced blood pressure significantly 13/6 mm Hg (25 mg) and 17/10 mm Hg (50 mg) in contrast to propranolol. Resistance in the fore-arm (plethysmography) fell significantly with carvedilol 50 mg whereas propranolol caused a significant rise. After 4 weeks both compounds had reduced blood pressure significantly and to the same extent. Blood flow was still reduced with propranolol in contrast to the findings with carvedilol. We conclude that carvedilol given orally has a useful antihypertensive effect both acutely and during prolonged treatment. It has an attractive hemodynamic profile.

Abstract
Blood pressure at rest and cardiovascular response to "stress" were studied in 27 girls and 33 boys 11-16 years old. One group (HT, n = 23) had hypertensive mothers with a previous hypertensive pregnancy, another group (NT, n = 20) had normotensive mothers with a previous hypertensive pregnancy and the control group (C, n = 17) had normotensive mothers with normotensive pregnancies. Resting blood pressure was 124/71 mmHg (HT), 117/67 mmHg (NT) and 112/65 mmHg in the 3 groups. Systolic pressure was significantly different in all 3 groups (p less than 0.05 - p less than 0.001). Responses to noise stimulation (100 dBA) were identical in all groups with increases in diastolic and mean arterial blood pressure and cardiac output. During a video game session increases in blood pressure and heart rate were equal in the groups but during physical exercise a slight decrease in diastolic blood pressure was seen in the NT and C groups only. Differences in blood pressure in children with varying maternal history of hypertension do not seem to reflect alterations in the cardiovascular response pattern to "stress".

Abstract
Blood flow resistance was studied in two peripheral vascular beds in 15 patients with previous malignant hypertension and in matched groups of patients with "benign" hypertension and control subjects. Both hypertensive groups had significantly higher resistance in the hands (skin vessel bed) at maximal dilatation (2.5 and 2.5 U, respectively) than the normotensive group (1.9 U) (p less than 0.01). This increase indicates structural changes in the arteriolar wall in both hypertensive groups. It indicates a similar degree of adaptation of the vascular changes to the present blood pressure level in both hypertensive groups, although the initial blood pressure had been much higher in the group with previous malignant hypertension than in the group with "benign" hypertension. Different findings were made in the calves (muscle vessel bed), and the most severe changes were found in patients with previous malignant hypertension. Resistance at maximal dilatation was 2.4 U compared to 1.9 U in the group with "benign" hypertension (p less than 0.05) and 1.6 U in the control group (p less than 0.001 and p less than 0.05, respectively).

Abstract
Arterial pressure and other hemodynamic variables (stroke volume (SV), cardiac output and total peripheral resistance) were studied in 18 healthy males before and during exposure to recorded industrial noise. All measurements took place under strictly standardized conditions in a noise laboratory. the frequency distribution and level of noise used for stimulation were continuously monitored and kept constant within close limits throughout the experiments. SV was measured with impedance cardiography. Indirect blood pressure (BP) in the brachial artery was measured with an automatic device and the derived parameters, cardiac output and total peripheral resistance, were calculated from these measurements. Compared with resting conditions at 40 dBA, stimulation with industrial noise at 95 dBA caused significant increases in diastolic BP, mean arterial pressure and total peripheral resistance. Minor but statistically significant reductions of SV and cardiac output were seen. Heart rate and systolic BP did not change. These alterations of the hemodynamic variables persisted throughout 20 min of noise stimulation and were maintained for 5 min following cessation of noise stimulation. All variables had returned to their initial levels 10 min after discontinuation of noise stimulation. This study suggests that exposure to industrial noise at levels prevailing during several industrial processes may cause acute elevations of arterial BP and peripheral vascular resistance. In animal studies, repeated elevations of BP due to exposure to noise have been shown to cause a permanent elevation of BP. Therefore, we suggest that noise may be one of several external stimuli contributing to the development of arterial hypertension in man.

Abstract
AIM The long-term effects of reconstructions of the gastrointestinal tract after gastrectomy on plasma levels of gastrointestinal hormones that contribute to food intake controls were evaluated. MATERIALS AND METHODS Domestic pigs were randomly assigned to sham-surgery or total gastrectomy followed by reconstruction with oesophagojejunostomy on a Roux-en-Y loop (OJRY), jejunal interposition between the oesophagus and the duodenum (OJD), or an oesophagojejunostomy with a jejunal pouch reservoir (J-pouch) on a Roux-en-Y loop. Plasma levels of peptides were analysed by radioimmunoassay (RIA). RESULTS Ten weeks after surgery, levels of cholecystokinin (CCK) and pancreatic polypeptide (PP) were significantly lowered (79.6% and 67.0%, respectively) in animals with a J-pouch, but not in sham-operated animals or animals with OJRY or OJD, as compared to preoperative levels. The levels of neuropeptide Y (NPY) and peptide YY (PYY) remained unchanged, irrespective of the mode of reconstruction. CONCLUSION J-pouch, but not preservation of duodenal passage after total gastrectomy, lowers levels of CCK and PP, peptides that reduce food intake.

Abstract
AIM The long-term effects of gastrectomy and various reconstructions of the gastrointestinal tract on fasting plasma levels of gastrointestinal hormones known to contribute to the control of gastrointestinal motor function were evaluated in pigs. MATERIALS AND METHODS Domestic pigs were randomly selected to sham surgery or total gastrectomy (TG) followed by reconstruction with oesophago-jejunostomy on a Roux-en-Y loop (OJRY), jejunal interposition between the oesophagus and the duodenum (OJD), or an oesophagojejunostomy with a proximal jejunal pouch reservoir (J-pouch) on a Roux-en-Y loop. Blood was collected just before surgery and ten weeks later and peptide levels were analysed by radioimmunoassay. RESULTS Somatostatin levels were sustained at a high level after TG, regardless of the mode of reconstruction, but were significantly lower in sham-operated animals. Levels of vasoactive intestinal peptide (VIP), neurotensin and motilin were unchanged. CONCLUSION TG by itself leads to high levels of somatostatin long term, however, somatostatin, motilin, neurotensin and VIP are unaffected by the mode of reconstruction.

Abstract
OBJECTIVE An intervention to structure patient-key worker communication has been tested in a randomized controlled trial. The aim of this paper was to investigate effectiveness of the intervention in terms of moderators of effectiveness. METHOD A total of 507 patients with schizophrenia were included. Moderators of effectiveness were investigated using two-way anovas. RESULTS Patients with a better relationship with their key worker and a shorter duration of illness at baseline benefited more from the intervention in terms of quality of life. Patients who received the intervention who were in competitive employment or had a shorter duration of illness showed greater reduction of unmet needs. Older patients receiving the intervention had better treatment satisfaction. CONCLUSION Outcome of the intervention was moderated by patient characteristics. Moreover, the moderating characteristics varied depending on the specific outcome. Evidence on moderators is very limited, even though, they are significant for understanding, targeting and implementing complex interventions.

Abstract
Evidence for the existence of CLL-specific antigens recognized by the immune system can be gathered from the observation that many patients display monoclonal or oligoclonal expansions and skewed repertoire of T cells. In vitro functional studies have shown that tumor-specific T-cells are able to lyse the leukemic cells. Antileukemic cellular immunity may be boosted in vivo using dendritic cell-based immunotherapy. Our preclinical studies provide evidence that DC that had endocytosed apoptotic CLL cells (Apo-DC) were superior to fusion hybrids, tumor lysate or RNA in eliciting antileukemic T-cell responses in vitro. We have validated a method for enriching the small number of monocyte precursors present in the peripheral blood of CLL patients and utilize them for generating individualized, Apo-DC cellular vaccines. In most cases, a minimum of 50 x 10(6) Apo-DC could be generated, beginning with immunomagnetically enriched monocytes from a single leukapheresis product containing at least 1% CD14+ cells. Cryopreservation and thawing did not affect the phenotype or the T cell stimulatory function of Apo-DC. A phase I/II, open label clinical trial examining the feasibility, safety and immunogenicity of Apo-DC vaccination has been initiated. CLL patients receive 10(7) Apo-DC for at least five immunizations and monitored clinically and immunologically for 52 weeks. Three cohorts are accrued stepwise. Cohort I receives Apo-DC alone; Cohort II: Apo-DC+ repeated doses of low-dose GM-CSF; Cohort III: low-dose cyclophosphamide followed by Apo-DC + GM-CSF.

Abstract
OBJECTIVE No method has yet been established to summarise different objective indicators of social outcomes into one score. The study aimed to develop and test a simple, brief and meaningful index of social outcomes that can be used across a broad range of mental health studies and is potentially obtainable from routine documentation. METHOD An index capturing employment, accommodation and living situation (range from 0 to 6; SIX) was devised and tested in three longitudinal datasets of patients with severe mental illness from Germany, Sweden and the UK. RESULTS SIX showed an almost normal distribution cross-sectionally in all three datasets. Between 58 and 78% of patients changed scores over time. Change scores were weakly associated with change scores of symptoms, quality of life, global functioning and disability. CONCLUSION A simple method to summarise different indicators of social outcomes provides meaningful results. It can be widely used in research and routine care.

Abstract
The aim of this study was to develop and investigate psychometric properties of the Health Promotion Intervention Questionnaire, a newly developed instrument intended to measure patients' subjective experiences of health promotion interventions in the mental health services. Health promotion practice has often been contested; therefore, it is important to produce convincing evidence that health promotion initiated by the health-care services actually works. A cross-sectional study was performed in order to investigate health promotion interventions among mental health service outpatients. A sample of 135 patients was used to test the psychometric properties of a new questionnaire designed to measure subjective experiences of health promotion interventions carried out by the mental health services. The factor structure of the questionnaire was tested by means of principal component factor analysis with varimax rotation. Reliability was measured in terms of internal consistency of the factors and test-retest reliability in a subsample of patients. The final scale contained 19 items derived from four factors: alliance, empowerment, educational support, and practical support. In terms of internal consistency, reliability was found to be good, both for the overall scale and the subscales. Test-retest reliability was moderate or higher in 13 out of 19 items and poor in only one item. This questionnaire, developed to evaluate patients' experiences of health promotion interventions in mental health services, may be used as an alternative in further empirical studies. With additional testing, the questionnaire could facilitate the work of defining and evaluating health promotion interventions conducted by the mental health services.

Abstract
Mental health services have been lacking systematic health-promoting activities, and health is often perceived as the absence of disease from a biomedical perspective. It is vital to develop methods to assess perceived health among patients in a broader perspective. The aim of the study was to investigate construct validity of a newly developed health questionnaire intended to measure subjectively experienced health among patients in mental health services. A cross-sectional study, including a randomly selected sample of 139 outpatients in contact with the mental health services, was performed in order to explore the relationship between perceived health and self-reported levels of self-esteem, symptoms, empowerment, quality of life and experiences of stigmatization. Self-esteem, symptoms, empowerment and quality of life altogether accounted for 70% of the variation in overall perceived health. Overall perceived health showed positive associations to self-esteem, empowerment and quality of life and negative associations to psychiatric symptoms, discrimination and rejection experiences. The findings suggest that perceived health as measured by the health questionnaire can be a meaningful and valid construct that may be useful for measuring health in clinical mental healthcare practice and in mental health services research.

Abstract
Transcript accumulation of the 3C glue protein gene Sgs-4 was induced in cultured salivary glands of Drosophila third instar larvae by supplementing the culture medium with 20-OH-ecdysone. The salivary glands were isolated from hormone-deficient larvae of the temperature-sensitive mutant l(1)su(f)ts67g, which were shifted from permissive (25 degrees C) to restrictive temperature (30 degrees C) at 60 h after oviposition. At the permissive temperature the glue protein are expressed during the latter half of the third instar. At the restrictive temperature there is no detectable or an extremely reduced accumulation of the 3C glue protein gene transcripts in these larvae. Induction of transcript accumulation was demonstrated by increased amounts of glue gene RNAs in the 20-OH-ecdysone supplemented salivary glands. Maximum accumulation was reached within 1 h after supplementation. The induction of accumulation was inhibited by a concentration of cycloheximide that repressed total protein synthesis, suggesting that 20-OH-ecdysone acts indirectly on the 3C glue gene by inducing synthesis of a protein(s) required transcript accumulation. We also show that there is a more rapid disappearance of 3C transcripts from salivary glands cultured in the presence of 20-OH-ecdysone than from glands cultured in its absence. This hormone-induced disappearance is, in contrast to the 68C transcripts, not inhibited by cycloheximide.

Abstract
BACKGROUND Circulating myeloma cells (CMC), exhibiting the same immunoglobulin heavy-chain gene rearrangements as the plasma cells, are part of the myeloma clone. In this study, we evaluated the effect of idiotype (Id) vaccination on CMC. PATIENTS AND METHODS Eleven patients were immunized with the autologous Id in combinations with granulocyte-macrophage colony-stimulating factor and interleukin 12, and followed for CMC by quantitative real-time allele-specific PCR. Id-specific T cells were monitored by proliferation assay, enzyme-linked immunospot (interferon-gamma) assay, and quantitative real-time PCR for cytokines. Regulatory T (T(reg)) cells were analyzed by flow cytometry. RESULTS CMC were detected in 9 of 11 patients at start of vaccination. In four patients, CMC declined and two had a complete molecular remission. Further two patients had stable levels of CMC during follow-up, while in three patients CMC progressively increased. Six patients had a vaccine-induced Id-specific T-cell response. A significant correlation was observed between reduced/stable levels of CMC and the Id-specific T cells (P < 0.02). The frequency of T(reg) cells was decreased in immune responders, but increased in immune nonresponders (P < 0.05). No significant change in the serum M-protein concentration was, however, observed in any patient. CONCLUSION Id vaccination reduced CMC, which correlated with vaccine-induced Id-specific T cells. Further studies are warranted to analyze the clinical significance of CMC and clinical effects of Id vaccination.

Abstract
Even though the concept of health and its importance has been widely discussed in health care during recent decades, mental health services have been criticised for adopting a biomedical perspective, which does not sufficiently consider the concept of health. The aim of the present study was to investigate the psychometric properties of the Health Questionnaire, a newly developed questionnaire to measure patients' subjective experience of health in mental health services. A cross sectional study was performed using a sample of 139 outpatients in mental health services. A principal component analysis with varimax rotation was used to test the factor structure of the questionnaire. Cronbach's alpha was employed to test internal consistency and Cohen's Kappa assessed test-retest reliability. The final scale, which contained 22 items, derived from three factors (autonomy, social involvement, and comprehensibility) and showed a good reliability in terms of internal consistency. Test-retest reliability was moderate or better for 17 out of 22 items. The Health Questionnaire may enable further empirical studies on subjectively experienced health in mental health services and serve as a measure of outcome and to monitor quality of care.

Abstract
BACKGROUND Studies investigating the importance of social network, empowerment and experiences of stigma on subjective quality of life among persons with mental illness are rare. AIM This study aimed to investigate beliefs of devaluation/discrimination, actual rejection experiences, empowerment, social network and the relationship of these factors to subjective quality of life among subjects with mental illness. METHODS A cross-sectional study assessing beliefs of devaluation/discrimination, actual rejection experiences, empowerment, social network and subjective quality of life was performed on 150 subjects with mental illness. RESULTS The factors most prominently related to subjective quality of life were overall empowerment and overall social network. For a subgroup of subjects suffering from psychotic disorders there was a significant negative relationship between subjective quality of life and rejection experiences. This group also reported more frequent rejection experiences. CONCLUSION The findings indicate that persons with mental illness are a heterogeneous group with regard to the influence of social network, stigma and empowerment on subjective quality of life. The negative impact of actual rejection experiences might express that, in order to increase subjective quality of life, stigma must be addressed as a separate and important factor in its own right.

Abstract
BACKGROUND Patient-clinician communication is central to mental healthcare but neglected in research. AIMS To test a new computer-mediated intervention structuring patient-clinician dialogue (DIALOG) focusing on patients' quality of life and needs for care. METHOD In a cluster randomised controlled trial, 134 keyworkers in six countries were allocated to DIALOG or treatment as usual; 507 people with schizophrenia or related disorders were included. Every 2 months for 1 year, clinicians asked patients to rate satisfaction with quality of life and treatment, and request additional or different support. Responses were fed back immediately in screen displays, compared with previous ratings and discussed. Primary outcome was subjective quality of life, and secondary outcomes were unmet needs and treatment satisfaction. RESULTS Of 507 patients, 56 were lost to follow-up and 451 were included in intention-to-treat analyses. Patients receiving the DIALOG intervention had better subjective quality of life, fewer unmet needs and higher treatment satisfaction after 12 months. CONCLUSIONS Structuring patient-clinician dialogue to focus on patients' views positively influenced quality of life, needs for care and treatment satisfaction.

Abstract
Health promotion has become a widespread concept, although little empirical research as to its importance and outcome has been performed in the mental health field. The aim of the present study was to investigate the construct validity of a newly developed Health Promotion Intervention Questionnaire, intended to measure patients' subjectively experienced health-promoting interventions within mental health services. A total of 135 participants responded to the questionnaire and to validation measures assessing psychiatric symptoms, empowerment, helping alliance and satisfaction with care. Bivariate correlations showed that overall perceived health-promoting interventions were positively correlated to, helping alliance, client satisfaction with care and empowerment. Stepwise multiple regression analysis showed that the strongest relationship was found between perceived health promotion intervention and helping alliance. In conclusion, the construct validity of the scale was satisfactory, except for one of its subscales where further investigations are needed.

Abstract
INTRODUCTION The study tested whether four commonly used patient-rated outcomes are explained by only one factor, reflecting a general appraisal tendency of patients. METHOD Quality of life, needs and symptoms were rated by 92 patients in community mental health care at baseline and after 18 months and 6 years follow-up periods. At follow ups treatment satisfaction was also assessed. Scores and change scores were subjected to factor analyses. We then tested which individual items predicted factor scores. RESULTS One factor explained between 55% and 66% of the variance of the tested patient-rated outcomes cross-sectionally and longitudinally. Only change scores of treatment satisfaction loaded on a separate factor. Seven items consistently explained more than 80% of the variance of the general factor. CONCLUSION Four important patient-rated outcomes are uniformly and substantially influenced by a general tendency for positive or negative appraisals. This tendency can be assessed more simply than using currently established methods.

Abstract
BACKGROUND Social interaction is crucial for whether a person will successfully accomplish important life tasks. AIM AND METHOD This study investigated the importance of sociodemographic, clinical and self-perceived health-related factors for social interaction among 103 individuals with persistent mental illness, mainly psychoses, visiting an outpatient unit. RESULTS Bivariate analyses pointed to several relationships, especially between the health-related variables and both quantitative and qualitative aspects of the social network. In multivariate analyses, higher levels of quality of life, self-esteem, being a cohabitant, and living in a house were related to higher ratings on different aspects of the social network. Older age was associated with fewer close relationships but more adequate social integration. CONCLUSIONS The social network appeared to be a function of both self-perceptions and sociodemographic influences. The influence is probably dynamic and, for example, just as a better quality of life may lead to more social interaction, a more developed social network probably promotes better quality of life. Therefore, interventions in mental health care that target social interaction constitute a powerful resource and should be part of the support for people with severe and persistent mental illness.

Abstract
The aim of this article is to present updated guidelines for the use of serum, tissue and faecal markers in colorectal cancer (CRC). Lack of specificity and sensitivity preclude the use of all existing serum markers for the early detection of CRC. For patients with stage II or stage III CRC who may be candidates for either liver resection or systemic treatment should recurrence develop, CEA should be measured every 2-3 months for at least 3 years after diagnosis. Insufficient evidence exists to recommend routine use of tissue factors such as thymidylate synthase, microsatellite instability (MSI), p53, K-ras and deleted in colon cancer (DCC) for either determining prognosis or predicting response to therapy in patients with CRC. Microsatellite instability, however, may be used as a pre-screen for patients with suspected hereditary non-polyposis colorectal cancer. Faecal occult blood testing but not faecal DNA markers may be used to screen asymptomatic subjects 50 years or older for early CRC.

Abstract
BACKGROUND A major goal in mental health research and policy is to identify ways to reduce stigma among persons with mental illness. AIMS The aims of the present study were to (1) investigate the prevalence of rejection and devaluation/discrimination in a cross-sectional sample of 200 individuals with experiences of mental illness and (2) investigate the relationship between sociodemographic and clinical, client characteristics and perceived devaluation/discrimination and experiences of rejection. METHODS A total of 200 subjects in current contact with mental health services or with earlier experiences of this were interviewed regarding beliefs about devaluation/discrimination and rejection experiences. RESULTS The results showed that subjects with a higher degree of global functioning perceived less devaluation/discrimination. With regard to rejections experiences associations were found between rejection experiences and global functioning, number of admissions to inpatient psychiatric care and current contact with social services. CONCLUSION Further research should investigate the causal relationship between stigma experiences and psychosocial functioning. To understand what consequences perceived devaluation/discrimination has for the afflicted, a psychological and social approach in the research must be taken into consideration.

Abstract
Marine organisms have evolved defence mechanisms to prevent epibiosis. This study investigated the anti-settlement properties of natural periostracal microtopographies of two mytilid species, Mytilus edulis (from North, Baltic and White Seas) and Perna perna (from the SW Atlantic). Resin replicas of shells were exposed to cyprids of the barnacle Semibalanus balanoides. Replicas with intact isotropic microtopographies and smooth controls were much less fouled than roughened anisotropic surfaces. This indicates that in both M. edulis and P. perna the periostracum possesses a generic anti-settlement property, at least against S. balanoides cyprids, which is not regionally adapted. Such a potential globally effective anti-settlement mechanism possibly contributes to the invasive success of Mytilidae.
