The validity and reliability of the Swedish version of the Satisfaction with appearance scale for individuals with systemic sclerosis. JOURNAL OF SCLERODERMA AND RELATED DISORDERS 2023; 8:53-63. [PMID: 36743814 PMCID: PMC9896191 DOI: 10.1177/23971983221107858] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 05/27/2022] [Indexed: 11/16/2022]
Abstract
Background Systemic sclerosis (SSc) can lead to visible changes in appearance which could generate concerns among patients. Thus, valid questionnaires that capture these concerns are valuable to identify and communicate appearance concerns. Objective To determine aspects of the validity and reliability of the Swedish version of the Satisfaction with Appearance scale for individuals with SSc (SWAP-Swe in SSc). Methods Content validity was assessed by interviews. In a cross-sectional design, construct validity was evaluated by comparing the self-reported questionnaire SWAP-Swe in SSc to the Scleroderma Health Assessment Questionnaire (SSc HAQ), Patient Health Questionnaire-8 (PHQ-8), RAND-36, modified Rodnan skin score (mRSS), disease duration and age using Spearman's rank correlations (rs ). Internal consistency was evaluated by Cronbach's alpha coefficient and corrected item-to-total correlations. Test-retest reliability was investigated using the intraclass correlation coefficient (ICC). Results Eleven patients and 10 health professionals participated in the assessment of content validity. For the other aspects of validity and reliability 134 patients (median age 62 years, women 81%, limited cutaneous SSc 75%) participated. Overall, the content validity was satisfactory. The SWAP-Swe in SSc correlated with SSc HAQ (HAQ-DI rs = 0.50, visual analogue scales rs = 0.24-0.41), PHQ-8 (rs = 0.46), RAND-36 (rs = -0.21 to -0.47), mRSS (rs = 0.28), disease duration (rs = -0.01) and age (rs = -0.15). The Cronbach's alpha coefficient was 0.92, corrected item-to-total correlations ⩾ 0.45 and the ICC 0.82. Conclusion The SWAP-Swe in SSc showed satisfactory content validity, sufficient and good internal consistency and sufficient test-retest reliability. It was more strongly associated with self-reported questionnaires than with physician-assessed skin involvement and age, indicating that appearance concerns in SSc seem to be multidimensional as earlier reported. Our study contributes with a thorough investigation of validity and reliability including aspects that have not been investigated before. However, evaluation of more validity aspects of the SWAP-Swe in SSc is suggested.

Exploring the effects of a combined exercise programme on pain and fatigue outcomes in people with systemic sclerosis: study protocol for a large European multi-centre randomised controlled trial. Trials 2022; 23:962.

Abstract
Abstract
Background
Pain, related to Raynaud’s phenomenon or digital ulceration, has been identified as very prevalent and debilitating symptoms of systemic sclerosis (SSc), both significantly affecting patients’ quality of life (QoL). Pharmacological therapeutic strategies were found not to be sufficiently effective in the management of SSc-induced pain and fatigue, and evidence for exercise is scarce. As yet, the effects of a long-term, tailored exercise programme on pain and fatigue in patients with SSc have not been explored. In addition to pain and fatigue, this study aims to evaluate the effects of exercise on QoL, physical fitness, functional capacity, and vascular structure in people with SSc (PwSSc).
Methods
This will be a multicentre (n = 6) randomised controlled clinical trial to assess the effect of a previously established, supervised 12-week combined exercise programme on pain and fatigue as compared to no exercise in PwSSc. The study will recruit 180 patients with SSc that will be allocated randomly to two groups. Group A will perform the exercise programme parallel to standard usual care and group B will receive usual care alone. Patients in the exercise group will undertake two, 45-min sessions each week consisting of 30-min high-intensity interval training (HIIT) (30-s 100% peak power output/30-s passive recovery) on an arm crank ergometer and 15 min of upper body circuit resistance training. Patients will be assessed before as well as at 3 and 6 months following randomisation. Primary outcomes of the study will be pain and fatigue assessed via questionnaires. Secondary outcomes include quality of life, structure of digital microvasculature, body composition, physical fitness, and functional capacity.
Discussion
Data from this multi-centre research clinical trial will primarily be used to establish the effectiveness of a combined exercise protocol to improve pain and fatigue in SSc. In parallel, this study will be the first to explore the effects of long-term exercise on potential microvascular alterations assessed via NVC. Overall, this study will provide sufficient data to inform current clinical practice guidelines and may lead to an improvement of QoL for patients with SSc.

The Experiences of Functioning and Health of Patients With Primary Sjögren's Syndrome: A Multicenter Qualitative European Study. Front Med (Lausanne) 2021; 8:770422. [PMID: 34869487 PMCID: PMC8637170 DOI: 10.3389/fmed.2021.770422] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 10/05/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: To identify a spectrum of perspectives on functioning and health of patients with primary Sjögren's syndrome (pSS) from the five European countries in order to reveal commonalities and insights in their experiences. Methods: A multicenter focus group study on the patients with pSS about their perspectives of functioning and health was performed. Focus groups were chaired by trained moderators based on an interview guide, audiotaped, and transcribed. After conducting a meaning condensation analysis of each focus group, we subsequently combined the extracted concepts from each country and mapped them to the International Classification of Functioning, Disability and Health (ICF). Results: Fifty-one patients with pSS participated in 12 focus groups. We identified a total of 82 concepts meaningful to people with pSS. Of these, 55 (67%) were mentioned by the patients with pSS in at least four of five countries and 36 (44%) emerged in all the five countries. Most concepts were assigned to the ICF components activities and participation (n = 25, 30%), followed by 22 concepts (27%) that were considered to be not definable or not covered by the ICF; 15 concepts (18%) linked to body structures and functions. Participants reported several limitations in the daily life due to a mismatch between the capabilities of the person, the demands of the environment and the requirements of the activities. Conclusion: Concepts that emerged in all the five non-English speaking countries may be used to guide the development and adaption of the patient-reported outcome measures and to enhance the provision of treatment options based on the aspects meaningful to patients with pSS in clinical routine.

Abstract
ObjectiveTo investigate aspects of validity and reliability of the Swedish version of the Self-Efficacy for Managing Chronic Disease (SEMCD-Swe) scale in systemic sclerosis (SSc).Method: A forward-backward translation procedure was used. Content validity was assessed through interviews with 11 people with SSc and 10 healthcare professionals. Construct validity, internal consistency, test-retest reliability, and floor and ceiling effects were evaluated in 104 SSc patients.Results: The content validity of the SEMCD-Swe was interpreted as satisfactory, but some adjustments were made to increase the understanding. Confirmatory factor analysis supported a single-factor structure. Moderate to strong correlations between the SEMCD-Swe and Scleroderma Health Assessment Questionnaire; Multidimensional Assessment of Fatigue; Patient Health Questionnaire-8 (rs = -0.4 to -0.7), and RAND-36 subscales (rs = 0.5 to 0.7) were found. Weak correlations were found between SEMCD-Swe and modified Rodnan skin score; and disease severity of peripheral vascular and lung (rs = -0.1 to -0.2) and kidney (rs = 0.1) systems (Medsger severity scale). Cronbach's alpha was sufficient (0.85) and corrected item-to-total correlations were good (≥ 0.50). The intraclass correlation coefficient for the total score was sufficient (0.82). No floor or ceiling effects were found.Conclusion: Support for construct validity was indicated, as the SEMCD-Swe in SSc show a single-factor structure and is more strongly associated with pain, fatigue, depressive symptoms, interferences with daily activities, disability, and quality of life than with disease severity. Our results also indicate support for content validity and reliability. However, the responsiveness of the SEMCD-Swe needs to be tested.

Abstract
INTRODUCTION Systemic sclerosis (SSc; scleroderma) is a rare, chronic, autoimmune disease with a high level of burden, a significant impact on the ability to carry out daily activities, and a considerable negative impact on health-related quality of life. Non-pharmacological interventions could be provided to potentially improve mental and physical health outcomes. However, the effectiveness of non-pharmacological interventions on health and well-being among individuals with SSc has not been well established. The proposed living systematic review aims to identify and evaluate randomised controlled trial (RCT) evidence on the effectiveness of non-pharmacological and non-surgical interventions on mental and physical health outcomes and on the delivery of such services in SSc. METHODS AND ANALYSIS Eligible studies will be RCTs that examine non-pharmacological and non-surgical interventions aimed at improving health outcomes among individuals with SSc or the delivery of services intended to improve healthcare or support of people with SSc (eg, support groups). All RCTs included in a previous systematic review that sought studies published between 1990 and March 2014 will be evaluated for inclusion. Additional trials will be sought from January 2014 onwards using a similar, augmented search strategy developed by a health sciences librarian. We will search the MEDLINE, Embase, CINAHL, PsycINFO, Cochrane Library and Web of Science databases and will not restrict by language. Two independent reviewers will determine the eligibility of identified RCTs and will extract data using a prespecified standardised form in DistillerSR. Meta-analyses will be considered if ≥2 eligible RCTs report similar non-pharmacological interventions and comparable health outcomes. We will conduct a qualitative synthesis for interventions that cannot be synthesised via meta-analysis. ETHICS AND DISSEMINATION We will post initial and ongoing results via a website, publish results periodically via peer-reviewed journal publication, and present results at patient-oriented events. PROSPERO REGISTRATION NUMBER CRD42020219914.

Profiling of donor-specific immune effector signatures in response to rituximab in a human whole blood loop assay using blood from CLL patients. Int Immunopharmacol 2021; 90:107226. [PMID: 33316742 DOI: 10.1016/j.intimp.2020.107226] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2020] [Revised: 11/04/2020] [Accepted: 11/18/2020] [Indexed: 12/27/2022]
Abstract
Rituximab is widely used in the treatment of haematological malignancies, including chronic lymphocytic leukaemia (CLL), the most common leukaemia in adults. However, some patients, especially those with high tumour burden, develop cytokine release syndrome (CRS). It is likely that more patients will develop therapy-linked CRS in the future due to the implementation of other immunotherapies, such as CAR T-cell, for many malignancies. Current methods for CRS risk assessment are limited, hence there is a need to develop new methods. To better recapitulate an in vivo setting, we implemented a unique human whole blood "loop" system to study patient-specific immune responses to rituximab in blood derived from CLL patients. Upon rituximab infusion, both complement-dependent cytotoxicity (CDC) and antibody-dependent cellular cytotoxicity (ADCC) profiles were evident in CLL patient blood, coincident with CLL cell depletion. Whereas B cell depletion is induced in healthy persons in the blood loop, only patients display B cell depletion coupled with CRS. With the exception of one donor who lacked NK cells, all other five patients displayed variable B cell depletion along with CRS profile. Additionally, inhibition of CDC or ADCC via either inhibitors or antibody Fc modification resulted in skewing of the immune killing mechanism consistent with published literature. Herein we have shown that the human whole blood loop model can be applied using blood from a specific indication to build a disease-specific CRS and immune activation profiling ex vivo system. Other therapeutic antibodies used for other indications may benefit from antibody characterization in a similar setting.

Abstract
Background Depressive symptoms are common in rheumatic diseases and influence patients’ quality of life. The Patient Health Questionnaire-9 (PHQ-9), which assesses symptoms of depression, is valid in English in patients with systemic sclerosis (SSc). However, the measurement properties of the PHQ-8 (short version of the PHQ-9) have not been evaluated in Swedish patients with SSc. Objective To investigate different aspects of validity and reliability of the PHQ-8 in Swedish (PHQ-8 Swe) for individuals with SSc. Methods A total of 101 patients with SSc participated. Content validity was evaluated via interviews of 11 patients and 10 health professionals. Construct validity, internal consistency test–retest reliability, and floor/ceiling effects were evaluated in 90 patients. Results Content validity was satisfactory, but some linguistic adjustments were made. Confirmatory factor analysis supported a better fit for a two-factor structure. Moderate-to-strong correlations were found between the PHQ-8 Swe and scleroderma HAQ including VAS (rs = 0.4–0.7); Multidimensional Assessment of Fatigue (rs = 0.7); RAND-36 subscales (rs = − 0.5 to − 0.8); and lung disease severity (Medsger scores) (rs = 0.4). There were weak correlations (rs = <0.4) between the PHQ-8 Swe and modified Rodnan skin score; and vascular, heart, and kidney disease severity. Cronbach’s alpha was 0.85, corrected item-to-total correlations were >0.40, and the ICC for the total score was 0.83. No floor/ceiling effects were found. Conclusion The PHQ-8 Swe has satisfactory content validity and sufficient reliability in patients with in majority limited SSc. It is more strongly associated with self-reported disability, pain, disease interferences with daily activities, fatigue, and quality of life than with disease severity, except for a moderate association with lung severity.

Abstract
The remarkable clinical heterogeneity in chronic lymphocytic leukaemia (CLL) has highlighted the need for prognostic and predictive algorithms that can be employed in clinical practice to assist patient management and therapy decisions. Over the last 20 years, this research field has been rewarding and many novel prognostic factors have been identified, especially at the molecular genetic level. Whilst detection of recurrent cytogenetic aberrations and determination of the immunoglobulin heavy variable gene somatic hypermutation status have an established role in outcome prediction, next-generation sequencing has recently revealed novel mutated genes with clinical relevance (e.g. NOTCH1, SF3B1 and BIRC3). Efforts have been made to combine variables into prognostic indices; however, none has been universally adopted. Although a unifying model for all groups of patients and in all situations is appealing, this may prove difficult to attain. Alternatively, focused efforts on patient subgroups in the same clinical context and at certain clinically relevant 'decision points', that is at diagnosis and at initiation of first-line or subsequent treatments, may provide a more accurate approach. In this review, we discuss the advantages and disadvantages as well as the clinical applicability of three recently proposed prognostic models, the MD Anderson nomogram, the integrated cytogenetic and mutational model and the CLL-international prognostic index. We also consider future directions taking into account novel aspects of the disease, such as the tumour microenvironment and the dynamics of (sub)clonal evolution. These aspects are particularly relevant in view of the increasing number of new targeted therapies that have recently emerged.

Abstract
BACKGROUND Systemic sclerosis (SSc) is an autoimmune disease where thickening of the skin can lead to reduced body function and limitations in activities. Severe forms can also affect and seriously damage inner organs. Patient-centred rehabilitation emphasises considerations of patients' background, experience and behavior which highlights the need to know if patient-reported outcome measures (PROMs) include such personal factors. AIM To identify and describe personal factors in the experiences of functioning and health of persons with SSc and to examine if and to what extent PROMs in SSc research cover these factors. DESIGN Data from a qualitative study with focus group interviews were analysed. PROMs in SSc research were identified in a literature review between 2008-2013. SETTING Participants were recruited from outpatient clinics at rheumatology department. POPULATION Sixty-three patients with SSc from four European countries participated. METHODS Data from interviews were analysed using a structure of personal factors developed by Geyh et al. Identified PROMs were analysed and linked to main concepts, related to the personal factors, found in the interview data. RESULTS Nineteen main concepts were related to the area "patterns of experience and behaviour" in the personal factor structure, 16 to "thoughts and beliefs", nine to "feelings", one to "motives" and one to "personal history and biography", respectively. Among the 35 PROMs identified, 15 did not cover any of the identified concepts. Concepts within the area "feelings" were mostly covered by the PROMs. Five of the PROMs covered "patterns of experience and behaviour", while "motives" and "personal history and biography" were not covered at all. Four of the identified PROMs covered concepts within the areas "feelings", "thoughts and beliefs" and "patterns of experience and behaviour" in the same instrument. The Illness Cognition Questionnaire and Illness Behaviour Questionnaire were such PROMs. CONCLUSION Patterns of experience and behaviour had the highest number of concepts related to personal factors, but few of the PROMs in SSc research covered these factors. Only a few PROMs covered several personal factors areas in the same instrument. CLINICAL REHABILITATION IMPACT The results would be of value when developing core sets for outcome measurements in SSc.

Abstract
Background Personal factors (PFs) are internal factors that determine functioning and the individuals’ experience of disability. Their coverage by patient-reported outcome measures (PROMs) has not been examined in rheumatoid arthritis (RA) so far. The aims of this study were to identify PFs important in the life stories of people with RA and to determine their coverage by PROMs used in RA. Methods The qualitative data of people with RA was explored to identify PFs. Additionally a systematic literature search was conducted to find PROMs used in RA. PROMs items were linked to the components, domains and categories of the International Classification of Functioning, Disability and Health (ICF) to determine the coverage of important PFs by PROMs. Results Twelve PFs were found to be important in the life stories of people with RA. The PFs coping and reflecting about one’s life in an optimistic way were covered most frequently, each by 14 of the 42 explored PROMs, while job satisfaction was not covered at all. The London Coping with Rheumatoid Arthritis Questionnaire, General Self-Efficacy Scale, Arthritis Self-Efficacy Scale, Rheumatoid Arthritis Self-Efficacy Questionnaire and Revised Ways of Coping Inventory covered most PFs. Nineteen PROMs did not cover any of the PFs. Conclusion Several PFs were identified as important in the life stories of people with RA, but only 55% of the PROMS covered some of these PFs. When evaluating PFs important to people with RA, health professionals should be alert on which PROMs can be used to assess which PFs.

Abstract
UNLABELLED Systemic lupus erythematosus (SLE) is a chronic disease which can affect any organ, and the impact of the condition will affect each person differently. There are few qualitative studies including the experiences of both women and men with a diagnosis of SLE corresponding to the American College of Rheumatology (ACR) criteria where both negative and positive impacts of the disease have been presented. PURPOSE The aim was to describe how patients with established SLE experience their illness in everyday life, including both negative and positive aspects. METHOD Four focus group interviews were conducted with 16 women and three men with SLE according to ACR criteria, with varied disease activity and no or little organ damage. The interviews were tape recorded, transcribed verbatim and analysed using qualitative content analysis. RESULTS Two themes emerged: multifaceted uncertainty contained the categories 'an unreliable body', 'obtrusive pain and incomprehensible fatigue', 'mood changes and worries', 'reliance on medication and health care'; Focus on health and opportunities included 'learning process implying personal strength', 'limitations and possibilities in activities and work', 'a challenge to explain and receive support' and 'living an ordinary life incorporating meaningful occupations'. CONCLUSIONS While we expected to find a mainly negative impact, positive aspects were also described. Our findings were complex and showed that patients with established SLE can experience both uncertainty and opportunities. This highlights the importance for healthcare professionals of gaining a better understanding of patients' uncertainty, to enable them to support patients, allowing them to focus on health and opportunities. Measurement instruments that capture different aspects of uncertainty and opportunities needs to be developed.

Abstract
UNLABELLED Several studies have found that indoor air quality (IAQ) in schools is often poor and may affect the health of the pupils. Building ventilation is a means to reduce pollutants indoors, but different designs should be evaluated for their effectiveness in different environments. In a field experiment performed at four classrooms in one school building, air was supplied either in the mixing or in the displacement mode, and we collected information on exposures, pupils' perception of IAQ and climate, and health symptoms and performed clinical examinations. The room temperature, relative humidity, concentration of CO₂, and cat allergen were measured at the breathing height and were similar during each ventilation mode. The children perceived IAQ were similar in the two ventilation regimes, and there were few differences in symptom reports or clinical parameters. However, the pupils reported more eye symptoms during displacement ventilation. PRACTICAL IMPLICATIONS Both mixing and displacement ventilation may be appropriate in school classrooms as long as the overall design, ventilation rates, and maintenance of systems are satisfactory.

Abstract
Objective To describe the experiences of people with systemic sclerosis (SSc) in different European countries of functioning and health and to link these experiences to the WHO International Classification of Functioning, Disability and Health (ICF) to develop a common understanding from a bio-psycho-social perspective. Method A qualitative multicentre study with focus-group interviews was performed in four European countries: Austria, Romania, Sweden and Switzerland. The qualitative data analysis followed a modified form of ‘meaning condensation’ and the concepts that emerged in the analysis were linked to the ICF. Results 63 people with SSc participated in 13 focus groups. In total, 86 concepts were identified. 32 (37%) of these were linked to the ICF component body functions and structures, 21 (24%) to activities and participation, 26 (30%) to environmental factors, 6 (7%) to personal factors and 1 (1%) to the health condition itself. 19 concepts (22%) were identified in all four countries and included impaired hand function, household activities, paid work, drugs, climate and coldness, support from others and experiences with healthcare institutions, non-pharmacological treatment, social security and benefits. Conclusion Concepts identified in all four countries could be used for guiding clinical assessment, as well as interdisciplinary team care and rheumatological rehabilitation for patients with SSc. For a full understanding of the aspects of the disease that were most relevant to people with SSc, people with SSc from multiple countries needed to be involved.

Abstract
Despite much effort to positively affect long-term outcome in psychosis and schizophrenia many patients are still facing a poor outcome with persistent psychotic symptoms and decline in social functioning. the aim of this study was to examine the relationship between financial strain and social network and five-year outcome of first episode psychosis (FEP). FEP patients were divided into recovered (n = 52) and non-recovered (n = 19). Each personwas matched according to age and gender with fourpersons (n = 284) from a longitudinal populationbasedstudy. All persons had answered an extensivequestionnaire including social network, quantitative and qualitative, financial strain and mental health. Linear regression analysis showed that both financial strain and social network were associated, and had a unique contribution, to outcome. the results indicate that FEP patients might benefit from interventions that reduce financial strain thus facilitating daily life and cultural and social activities.

Abstract
OBJECTIVE The aim was to translate, test, and describe aspects of reliability and validity of the Fatigue Severity Scale (FSS) in Swedish (FSS-Swe) in patients with systemic lupus erythematosus (SLE). METHODS Patients with stable SLE, low or moderate disease activity, and low organ damage were included. Forward and back translations of the FSS were performed. Construct validity was tested with 32 women using a first Swedish translation. Feasibility, ceiling and floor effects, internal consistency, test-retest reliability, and content validity were tested on a slightly modified final version of the FSS-Swe in a non-selected group of patients (n = 23). RESULTS There were correlations (p< or =0.05) between the FSS-Swe and overall disease activity according to the Systemic Lupus Activity Measure (SLAM) (r(s) = 0.48) and the SLAM Visual Analogue Scale (SLAM-VAS) (r(s) = 0.46); between the FSS-Swe and eight subscales of the Swedish 36-Item Medical Outcomes Study Short-Form Health Survey (SF-36) (r(s) = -0.41 to -0.65) and between the FSS-Swe and age (r(s) = -0.35). All patients answered all FSS-Swe questions at both test and retest. There was one ceiling effect in one question on one occasion. The Kolmogorov-Smirnov test indicated normal distribution. Cronbach's alpha was 0.94 and corrected item-to-total correlation exceeded 0.3. There were no significant systematic test-retest differences, and the median-weighted kappa coefficient was 0.75. Twenty patients understood the questions in FSS-Swe, 18 considered they were relevant, reflected their fatigue, and that none should be excluded. Five items were suggested to be included. CONCLUSIONS The FSS-Swe supports construct validity, is feasible, has no important ceiling or floor effects, has satisfactory internal consistency, substantial test-retest reliability, and satisfactory content validity in the SLE patients studied. However, its sensitivity to change needs to be tested.

Abstract
OBJECTIVE To evaluate "need-specific treatment" of first episode schizophrenia syndrome patients. METHOD Sixty-one consecutive first episode schizophrenia syndrome patients were followed over 3 years. They were compared with a Historical "treatment as usual" group (n = 41) and a Prospective group from a high quality social and biological psychiatry centre (n = 25). RESULTS Symptomatic and functional outcome was significantly better compared with the Historical group and equal with the Prospective group. During the first year, the direct costs for in- and out-patient care per patient in the Parachute project were less than half of those in the Prospective group. CONCLUSION The study confirms the feasibility, clinically and economically, with a large scale application of "need-specific treatments" for first episode psychotic patients.

Abstract
OBJECTIVE Implementing a system designed to treat first episode psychotic (FEP) patients. METHOD Every FEP patient (n=253) from a catchment area of 1.5 million inhabitants were asked to participate in this 5-year project. One historical (n=71) and one prospective (n=64) FEP group were used for comparisons. RESULTS A total of 175 patients (69%) were followed up through the first year of treatment. Global Assessment of Functioning (GAF) values were significantly higher than in the historical comparison group but similar to the prospective group. Psychiatric in-patient care was lower as was prescription of neuroleptic medication. Satisfaction with care was generally high in the Parachute group. Access to a small overnight crisis home was associated with higher GAF. CONCLUSION It is possible to successfully treat FEP patients with fewer in-patient days and less neuroleptic medication than is usually recommended, when combined with intensive psychosocial treatment and support.

Abstract
Much controversy exists about whether or not NH(+)(4) is translocated in the xylem from roots to shoots. In this paper it is shown that such translocation can indeed take place, but that interference from other metabolites such as amino acids and amines may give rise to large uncertainties about the magnitude of xylem NH(+)(4) concentrations. Elimination of interference requires sample stabilization by, for instance, formic acid or methanol. Subsequent quantification of NH(+)(4) should be done by the OPA-fluorometric method at neutral pH with 2-mercaptoethanol as the reducing agent since this method is sensitive and reliable. Colorimetric methods based on the Berthelot reaction should never be used, as they are prone to give erroneous results. Significant concentrations of NH(+)(4), exceeding 1 mM, were measured in both xylem sap and leaf apoplastic solution of oilseed rape and tomato plants growing with NO(-)(3) as the sole N source. When NO(-)(3) was replaced by NH(+)(4), xylem sap NH(+)(4) concentrations increased with increasing external concentrations and with time of exposure to NH(+)(4). Up to 11% of the translocated N was constituted by NH(+)(4). Glutamine synthetase (GS) incorporates NH(+)(4) into glutamine, but root GS activity and expression were repressed when high levels of NH(+)(4) were supplied. Ammonium concentrations measured in xylem sap sampled just above the stem base were highly correlated with NH(+)(4) concentrations in apoplastic solution from the leaves. Young leaves tended to have higher apoplastic NH(+)(4) concentrations than older non-senescing leaves. The flux of NH(+)(4) (concentration multiplied by transpirational water flow) increased with temperature despite a decline in xylem NH(+)(4) concentration. Retrieval of leaf apoplastic NH(+)(4) involves both high and low affinity transporters in the plasma membrane of mesophyll cells. Current knowledge about these transporters and their regulation is discussed.

Abstract
Chlorinated fatty acids represent a recently discovered group of potentially hazardous organochlorine pollutants in the environment. The ability of human cells to incorporate and metabolise this type of fatty acids has never been investigated. The aim of the present study was, therefore, to investigate if two human cell lines, INT 407 and SH-SY5Y, incorporate and metabolise extracellular dichlorostearic acid. Cells were incubated with 9,10-dichlorostearic acid for 24 hr, and the amounts of chlorinated fatty acids in cells and culture medium analysed every two days for up to 6 or 10 days. Lipids were separated by solid phase extraction, transesterified to fatty acid methyl esters, and analysed by gas chromatography in combination with a halogen specific detector (GC/XSD). Dichlorostearic acid, dichloropalmitic acid and dichloromyristic acid were found in phospholipids and in neutral lipids of the INT 407 cells. Both cell lines secreted considerable amounts of dichloromyristic acid into the culture medium. Cellular or secreted metabolites shorter than dichloromyristic acid were not found. Taken together, the results suggest that human cells may (1) incorporate chlorinated fatty acids into membrane lipids and storage lipids, (2) metabolise cellular dichlorostearic acid to dichloropalmitic acid and dichloromyristic acid by B-oxidation; but that further metabolism is hindered, possibly because of the chlorine atoms, and (3) remove formed dichloromyristic acid by secretion. The removal of cellular dichloromyristic acid might represent an important cellular defence mechanism and deserves further investigations.

Abstract
A 3-year follow-up study was performed aimed at describing the outcome for severely affected stroke survivors who had undergone geriatric in-patient rehabilitation. Living conditions, psychological well-being, and changes in functions were assessed in 55 survivors. Twenty-five people were living in the community, 15 in apartment hotels or homes for the aged and 15 in nursing homes. From discharge to follow-up 11 people had had to move to an accommodation offering more support. Living alone, recurrent strokes and functional decline were associated with moving. Many of those living in the community were supported by relatives or home help services. Home adjustments and assistive devices were common and in most cases were aimed at facilitating transfers and bathroom activities. Motor function had deteriorated from discharge to follow-up, otherwise no statistically significant changes were seen in the survivors' abilities and functions. Most survivors had in fact been able to maintain their functions or to make further improvements. Also, their psychological well-being seemed quite good. These results should encourage rehabilitation efforts for elderly people severely affected by stroke.

Abstract
Mutants of barley (Hordeum vulgare L. cv Maris Mink) with 47 or 66% of the glutamine synthetase (GS) activity of the wild type were used for studies of NH3 exchange with the atmosphere. Under normal light and temperature conditions, tissue NH4+ concentrations were higher in the two mutants compared with wild-type plants, and this was accompanied by higher NH3 emission from the leaves. The emission of NH3 increased with increasing leaf temperatures in both wild-type and mutant plants, but the increase was much more pronounced in the mutants. Similar results were found when the light intensity (photosynthetic photon flux density) was increased. Compensation points for NH3 were estimated by exposing intact shoots to 10 nmol NH3 mol-1 air under conditions with increasing temperatures until the plants started to emit NH3. Referenced to 25[deg]C, the compensation points were 5.0 nmol mol-1 for wild-type plants, 8.3 nmol mol-1 for 47% GS mutants, and 11.8 nmol mol-1 for 66% GS mutants. Compensation points for NH3 in single, nonsenescent leaves were estimated on the basis of apoplastic pH and NH4+ concentrations. These values were 0.75, 3.46, and 7.72 nmol mol-1 for wild type, 47% GS mutants, and 66% GS mutants, respectively. The 66% GS mutant always showed higher tissue NH4+ concentrations, NH3 emission rates, and NH3 compensation points compared with the 47% GS mutant, indicating that NH4+ release was curtailed by some kind of compensatory mechanism in plants with only 47% GS activity.

Abstract
Depression is a common and serious complication after stroke. According to epidemiological studies, at least 30% of stroke patients experience depression, both early and late after stroke. However, in clinical practice only a minority of the patients are diagnosed and even fewer are treated. There are several studies confirming the magnitude of the problem but the main conclusion which can be drawn from the few treatment studies published is that tricyclic antidepressants cannot be recommended for the treatment of post-stroke depression, mainly because of the high frequency of contraindications and adverse effects. Until now there has only been 1 double-blind, placebo-controlled treatment study from which some general conclusions can be drawn. The study evaluated a selective serotonin reuptake inhibitor (citalopram) and concluded that the drug was well tolerated and effective for the treatment of post-stroke depression. However, when treatment was initiated very early, both the treatment group and the placebo group improved equally during the first 7 weeks after stroke. This finding could indicate diagnosis difficulties during the first few weeks after stroke. A recent study, although small, comparing the combination of drugs with either noradrenergic (desipramine plus mianserin) or noradrenergic and serotonergic effects (imipramine plus mianserin) for post-stroke depression, indicated that drugs with the dual effect may be more effective. Many more double-blind placebo-controlled treatment studies and studies comparing the efficacy and adverse effects of various antidepressants in patients with post-stroke depression need to be conducted. According to 3 small studies, electroconvulsive therapy (ECT) seems to be quite well tolerated and therefore ECT may also be considered in the treatment of post-stroke depression. Future studies should also address the long term efficacy of treatment for post-stroke depression.

Abstract
The present paper aims at describing historical features, developmental trends and key concepts in psychiatric physiotherapy (PPT). PPT was offered as an additional treatment to conventional psychiatric care and the aim was to examine the possibility of carrying out PPT with ten unselected patients (n = 10) in an out-patient psychiatric clinic. Symptoms presented: anxiety and phobic states, depression and crisis reactions. The purpose of four individual sessions was to stimulate curiosity and offer exercises concerning body-mind interactions. In examination of data qualitative research methods were used. All patients accepted the offer of PPT and participated in all sessions. Nine reported great or moderate symptom reduction. Of greatest importance for relief of symptoms was the patient's level of 'engagement'. PPT implies physical proximity and an encounter on an existential level. The impact of a complementary physical approach in psychiatric care needs to be further elucidated.

Effects of bicarbonate and oxygen concentration on photoinhibition of thylakoid membranes. PHOTOSYNTHESIS RESEARCH 1992; 34:263-270.

Abstract
The effects of bicarbonate and oxygen on photoinhibition of thylakoid membranes were investigated by varying their concentrations independently of each other. A pretreatment of the thylakoid suspension which lowered the bicarbonate concentration of the medium without affecting its oxygen content, increased the degree of photoinhibition upon illumination. This showed that the normal bicarbonate content of a thylakoid suspension, originating from dissolved carbondioxide from the air, protects against photoinhibition. The resistance against photoinhibition was further increased by addition of extra NaHCO3 up to about 5 mM. The normal oxygen content can be decreased profoundly without affecting the degree of photoinhibition; in contrast, even small changes from the normal bicarbonate content affected photoinhibition.At oxygen concentrations approximately below 25 μM, added NaHCO3 not only did not protect, but caused a more severe PS 2 inactivation. This was due to a blockage by added NaHCO3 of the recovery from a reversible photoinhibited state.Furthermore, it is shown that if the bicarbonate ions bound to high-affinity sites in PS 2 were replaced by formate ions, the thylakoid membranes became less susceptible to photoinhibition under normal oxygen tension.

Abstract
Cultured human SH-SY5Y neuroblastoma cells could be induced to differentiate morphologically and biochemically followed by growth inhibition, by treatment with 12-O-tetradecanoyl-phorbol-13-acetate (TPA). The cells showed a limited differentiation when treated with substances known to increase the intracellular concentration of cyclic AMP. When these substances were combined with TPA, morphological differentiation and growth inhibition of the cells were potentiated. In contrast, these substances inhibited the TPA-induced increase in noradrenaline concentration and the relative activity of neuron-specific enolase. Both the intracellular concentration of cyclic AMP and the cytosolic level of cyclic AMP-binding components were similar in control and TPA-treated cells. It is suggested that cyclic AMP has a limited and non-regulatory role in the initiation of differentiation of SH-SY5Y cells. The effect of cyclic AMP is probably coupled mainly to the polymerization of microtubules, thus enhancing the morphological differentiation of the cells.

Abstract
The dipeptide His-Phe, earlier shown to inhibit mammalian histidine decarboxylase, was analysed concerning its effect in vivo on pentagastrin-induced gastric acid secretion. Chronic gastric fistula rats were used and the effectors in saline were given as continuous i.v. infusions while acid was collected from the fistula. Addition of pentagastrin to the infusion solution resulted in an immediate increase in the acid output of the control runs. In the His-Phe experiments the dipeptide was introduced one hour before pentagastrin. A significant decrease in the acid output was obtained. This effect was optimal at a dose of about 6 mg/h and during the first few hours of the experiments. In spite of the continuous His-Phe infusion the acid secretion increased with time to the control values. These results are discussed in relation to preliminary observations on effects of alpha-fluoromethyl histidine on gastric acid secretion and the effect of this and His-Phe on gastric histamine content and histidine decarboxylase activity.
