Defining oligometastatic pancreatic cancer: a systematic review and critical synthesis of consensus.

BACKGROUND: Small retrospective series suggest that local consolidative treatment (LCT) may improve survival in oligometastatic pancreatic ductal adenocarcinoma (PDAC). However, no uniform definition of oligometastatic disease (OMD) in PDAC exists; this impedes meaningful conclusions. PATIENTS AND METHODS: A systematic literature search using PubMed, Web of Science, and Cochrane CENTRAL registries for studies and protocols reporting on definitions and/or LCT of OMD in PDAC was performed. The primary endpoint was the definition of OMD. Levels of agreement were categorized as consensus (≥75% agreement between studies), fair agreement (50%-74%), and absent/poor agreement (<50%). RESULTS: After screening of 5374 abstracts, the full text of 218 studies was assessed, of which 76 were included in the qualitative synthesis. The majority of studies were retrospective (n = 66, 87%), two were prospective studies and eight were study protocols. Studies investigated mostly liver (n = 38, 51%) and lung metastases (n = 15, 20%). Across studies, less than one-half (n = 32, 42%) reported a definition of OMD, while 44 (58%) did not. Involvement was limited to a single organ (consensus). Additional criteria for defining OMD were the number of lesions (consensus), metastatic site (poor agreement), metastatic size (poor agreement), treatment possibilities (poor agreement), and biomarker response (poor agreement). Liver OMD could involve three or fewer lesions (consensus) and synchronous disease (fair agreement), while lung metastases could involve two or fewer lesions and metachronous disease (consensus). The large majority of studies were at a high risk of bias or did not include any control groups. CONCLUSION: Definitions of OMD were not used or varied widely between studies hampering across-study comparability and highlighting an unmet need for a consensus. The present study is part of a multistep process that aims to develop an interdisciplinary consensus on OMD in pancreatic cancer.

Detection of a knockdown mutation in the voltage-sensitive sodium channel associated with permethrin tolerance in Sarcoptes scabiei var. hominis mites.

BACKGROUND: Increasing evidence has sparked a debate on the loss of sensitivity of scabies mites to conventional permethrin therapy. Mutations in the voltage-sensitive sodium channels (VSSC) were associated with knockdown resistance (kdr) in many arthropods, but have never been identified in Sarcoptes scabiei variatio (var.) hominis mites. OBJECTIVES: To identify factors contributing to therapy failure. METHODS: Sixty-seven mites were collected from 64 scabies-infested patients in Vienna, Austria, of whom 85.9% were refractory to prior permethrin-based treatments, and genotyped for the presence of nucleotide polymorphisms in Domain II of the VSSC, known to be associated with kdr. Information regarding previous antiscabietic therapies, decontamination procedures and possible re-infestations by contacts as well as the response to re-imposed therapies were obtained. RESULTS: Sequence alignment comparisons revealed previously unidentified mutations in the coding region of Domain II of the VSSC. A novel A1663T transversion was detected in 97.0% of the mites, resulting in a non-synonymous substitution from methionine to leucine, M918L, a mutation known to confer kdr in other arthropods. In addition, a synonymous G1659A transition was identified in one mite, which otherwise showed a nucleotide sequence identical to the wild-type reference. No major inconsistencies were observed within the previous therapeutic and decontamination procedures, which could have accounted for the observed non-responsiveness to permethrin-based therapies. Subsequent cure of infestation was achieved in 65.6% of the participants, predominantly by combination therapies with topical permethrin and systemic ivermectin. However, in 14.6% of the cured cases, permethrin monotherapy sufficed for eradication of scabies, albeit in some cases prolonged exposure was necessary. CONCLUSIONS: The kdr-associated M918L mutation in the VSSC gene has now emerged in S. scabiei var. hominis mites. Hence, loss of sensitivity to permethrin due to kdr-type resistance may be more prevalent than anticipated and may be decisive for the therapy responsiveness of scabies-infested patients.

International development of a patient-centered core outcome set for assessing health-related quality of life in metastatic breast cancer patients.

PURPOSE: For patients living with metastatic breast cancer (MBC), achieving best possible health-related quality of life, along with maximizing survival, is vital. Yet, we have no systemic way to determine if we achieve these goals. A Core Outcome Set (COS) that allows standardized measurement of outcomes important to patients, but also promotes discussing these outcomes during clinical encounters, is long overdue. METHODS: An international expert group (EG) of patient advocates, researchers, medical specialists, nurse specialists, and pharmaceutical industry representatives (n = 17) reviewed a list of relevant outcomes retrieved from the literature. A broader group (n = 141: patients/patient advocates (n = 45), health care professionals/researchers (n = 64), pharmaceutical industry representatives (n = 28), and health authority representatives (n = 4)) participated in a modified Delphi procedure, scoring the relevance of outcomes in two survey rounds. The EG finalized the COS in a consensus meeting. RESULTS: The final MBC COS includes 101 variables about: (1) health-related quality of life (HRQoL, n = 26) and adverse events (n = 24); (2) baseline patient characteristics (n = 9); and (3) clinical variables (n = 42). Many outcome that cover aspects of HRQoL relevant to MBC patients are included, e.g. daily functioning (including ability to work), psychosocial/emotional functioning, sexual functioning, and relationship with the medical team. CONCLUSION: The COS developed in this study contains important administrative data, clinical records, and clinician-reported measures that captures the impact of cancer. The COS is important for standardization of clinical research and implementation in daily practice and has received accreditation by the International Consortium for Health Outcomes Measurement (ICHOM).

[Lay version of the 2018 EULAR recommendations for physical activity in people with inflammatory arthritis and osteoarthritis : Translation into German and linguistic validation in German-speaking countries with people affected]. / Die laienverständliche Version der 2018 EULAR Empfehlungen zu körperlicher Aktivität von Menschen mit entzündlich-rheumatischen und degenerativen Erkrankungen : Übersetzung ins Deutsche und sprachliche Validierung im deutschsprachigen Raum mit Betroffenen.

BACKGROUND: Physical activity and exercise are beneficial for people with rheumatic diseases; however, recommendations for the management of rheumatoid arthritis (RA), spondyloarthritis (SpA) and hip- and knee osteoarthritis (HOA/KOA) are usually unspecific with respect to mode and dose of exercise. This is why the 2018 EULAR recommendations for physical activity in people with inflammatory arthritis and osteoarthritis were formulated. The recommendations consist of 4 overarching principles and 10 recommendations. These were also published as a lay version in the English language. AIM: Translation of the lay version into German and its linguistic validation in Austria, Germany and Switzerland. METHODS: A professional translation was reviewed by the authors, including people with, RA, SpA, HOA/KOA from the three German-speaking countries, which provided a prefinal lay version. Subsequently, eight interviews with people with RA, SpA, HOA/KOA were conducted in each country to evaluate understandability, wording, completeness and feasibility of the prefinal lay version. Finally, the authors, i.e. those with RA, SpA, and osteoarthritis, anonymously rated their agreement to the final lay version on a 0-10 scale. RESULTS: The professional translation was substantially revised by the authors and based on the interviews. Formulations were adapted to increase readability and understandability and specify statements. Comments that would have changed content or structure were not considered. Average agreement with the particular recommendations was between 10 (SD 0) and 7.6 (SD 1.67). DISCUSSION: For people with RA/SpA/HOA/KOA the EULAR physical activity recommendations should be available in their mother language. The final German lay version is valid and accepted across all three German-speaking countries. Thus, the physical activity recommendations can be provided to people with rheumatic diseases in an understandable and feasible way.

RECOMMENDATIONS FOR USE AND SCORING OF ORAL HEALTH IMPACT PROFILE VERSIONS.

BACKGROUND: OHIP's original seven-domain structure does not fit empirical data, but a psychometrically sound and clinically more plausible structure with the four OHRQoL dimensions Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact has emerged. Consequently, use and scoring of available OHIP versions need to be revisited. AIM: We assessed how well the overall construct OHRQoL and its four dimensions were measured with several OHIP versions (20, 19, 14, and 5 items) to derive recommendations which instruments should be used and how to score them. METHODS: Data came from the "Dimensions of OHRQoL Project" and used the project's learning sample (5,173 prosthodontic patients and general population subjects with 49-item OHIP data). We computed correlations among OHIP versions' summary scores. Correlations between OHRQoL dimensions, on one hand, and OHIP versions' domain scores or OHIP-5's items, on the other hand, were also computed. OHIP use and scoring recommendations were derived for psychometrically solid but also practical OHRQoL assessment. RESULTS: Summary scores of 5-, 14-, 19- and 49-item versions correlated highly (r = 0.91-0.98), suggesting similar OHRQoL construct measurement across versions. The OHRQoL dimensions Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact were best measured by the OHIP domain scores for Physical Disability, Physical Pain, Psychological Discomfort, and Handicap, respectively. CONCLUSION: Recommendations were derived which OHIP should be preferably used and how OHIP versions should be scored to capture the overall construct and the dimensions of OHRQoL. Psychometrically solid and practical OHRQoL assessment in all settings across all oral health conditions can be achieved with the 5-item OHIP.

Increased risk of death associated with the use of proton-pump inhibitors in patients with dementia and controls - a pharmacoepidemiological claims data analysis.

BACKGROUND AND PURPOSE: The use of proton-pump inhibitors (PPIs) was reported to be associated with increased mortality risk and has been proposed as a potential risk factor for neurodegenerative diseases. We aimed to assess the impact of PPI use on survival in patients with dementia as compared with controls. METHODS: This register-based control-matched cohort study included 28 428 patients with dementia ascertained by the prescription of antidementia drugs and two control individuals matched by sex, age and area of residence for each patient with dementia during the study period from 1 January 2005 to 30 June 2016. Cumulative defined daily doses (DDDs) of PPIs were extracted from the health insurance prescription registries. A multivariate Cox regression model for non-proportional hazards was used to analyse mortality risk in dependence of PPI exposure, which was limited to 1 year preceding the date of cohort entry (index date) in order to avoid immortal time bias. RESULTS: The PPI exposure of 100 DDDs in the year before the index date was associated with an increased mortality risk in patients with dementia (adjusted hazard ratio, 1.07; 95% confidence intervals, 1.03-1.12), but also in controls (adjusted hazard ratio, 1.47; 95% confidence intervals, 1.31-1.64). The mortality risk in relation to PPI use was significantly lower in patients with dementia as compared with controls (P < 0.0001) and highest in the first 2 years after the index date in both cohorts. CONCLUSIONS: Our findings promote more stringent pharmacovigilance strategies to avoid PPI use in cases lacking a clear indication for therapy or where potential risks outweigh the benefits.

Stressful life events are associated with striatal dopamine receptor availability in alcohol dependence.

Stress plays a key role in modulating addictive behavior and can cause relapse following periods of abstinence. Common effects of stress and alcohol on the dopaminergic system have been suggested, although the precise mechanisms are unclear. Here, we investigated 20 detoxified alcohol-dependent patients and 19 matched healthy controls and assessed striatal D2/D3 availability using [18F]-fallypride positron emission tomography and stressful life events. We found a strong association between striatal D2/D3 availability and stress in patients, but not in healthy controls. Interestingly, we found increased D2/D3 receptor availability in patients with higher stress levels. This mirrors complex interactions between stress and alcohol intake in animal studies and emphasizes the importance to investigate stress exposure in neurobiological studies of addiction. CLINICAL TRIAL REGISTRATION: NCT01679145.

Neural alterations of fronto-striatal circuitry during reward anticipation in euthymic bipolar disorder.

BACKGROUND: Bipolar disorder (BD), with the hallmark symptoms of elevated and depressed mood, is thought to be characterized by underlying alterations in reward-processing networks. However, to date the neural circuitry underlying abnormal responses during reward processing in BD remains largely unexplored. The aim of this study was to investigate whether euthymic BD is characterized by aberrant ventral striatal (VS) activation patterns and altered connectivity with the prefrontal cortex in response to monetary gains and losses. METHOD: During functional magnetic resonance imaging 20 euthymic BD patients and 20 age-, gender- and intelligence quotient-matched healthy controls completed a monetary incentive delay paradigm, to examine neural processing of reward and loss anticipation. A priori defined regions of interest (ROIs) included the VS and the anterior prefrontal cortex (aPFC). Psychophysiological interactions (PPIs) between these ROIs were estimated and tested for group differences for reward and loss anticipation separately. RESULTS: BD participants, relative to healthy controls, displayed decreased activation selectively in the left and right VS during anticipation of reward, but not during loss anticipation. PPI analyses showed decreased functional connectivity between the left VS and aPFC in BD patients compared with healthy controls during reward anticipation. CONCLUSIONS: This is the first study showing decreased VS activity and aberrant connectivity in the reward-processing circuitry in euthymic, medicated BD patients during reward anticipation. Our findings contrast with research supporting a reward hypersensitivity model of BD, and add to the body of literature suggesting that blunted activation of reward processing circuits may be a vulnerability factor for mood disorders.

Characterizing the concept of activity pacing as a non-pharmacological intervention in rheumatology care: results of an international Delphi survey.

OBJECTIVE: To develop a consensual list of the most important aspects of activity pacing (AP) as an intervention within the context of non-pharmacological rheumatology care. METHOD: An international, multidisciplinary expert panel comprising 60 clinicians and/or healthcare providers experienced in AP across 12 different countries participated in a Delphi survey. Over four Delphi rounds, the panel identified and ranked the most important goals of AP, behaviours of AP (the actions people take to meet the goal of AP), strategies to change behaviour in AP, and contextual factors that should be acknowledged when instructing AP. Additionally, topics for future research on AP were formulated and prioritized. RESULTS: The Delphi panel prioritized 9 goals, 11 behaviours, 9 strategies to change behaviour, and 10 contextual factors of AP. These items were integrated into a consensual list containing the most important aspects of AP interventions in non-pharmacological rheumatology care. Nine topics for future research on AP with the highest ranking were included in a research agenda highlighting that future research should focus on the effectiveness of AP interventions and on appropriate outcome measures to assess its effectiveness, as selected by 64% and 82% of the panellists, respectively. CONCLUSIONS: The diversity and number of items included in the consensual list developed in the current study reflect the heterogeneity of the concept of AP. This study is an important first step in achieving more transparency and homogeneity in the concept of AP in both rheumatology daily clinical practice and research.

Levothyroxine effects on depressive symptoms and limbic glucose metabolism in bipolar disorder: a randomized, placebo-controlled positron emission tomography study.

Adding supraphysiologic doses of levothyroxine (L-T4) to standard treatment for bipolar depression shows promise, but the mechanisms underlying clinical improvement are unknown. In a previous pilot study, L-T4 treatment reduced depression scores and activity within the anterior limbic network. Here we extended this work in a randomized, double-blind, placebo-controlled study of patients with bipolar depression. Cerebral glucose metabolism was assessed with positron emission tomography and [F-18]fluorodeoxyglucose before and after 6 weeks of treatment with L-T4 (n=15) or placebo (n=10) in 12 volumes of interest (VOIs): the bilateral thalamus, amygdala, hippocampus, dorsal striatum and ventral striatum, and midline cerebellar vermis and subgenual cingulate cortex. Radioactivity in the VOIs, normalized to whole-brain radioactivity was taken as a surrogate index of glucose metabolism, and markers of thyroid function were assayed. Changes in brain activity and their association with clinical response were assessed using statistical parametric mapping. Adjunctive L-T4 treatment produced a significant decline in depression scores during the 6-week treatment. In patients treated with L-T4, we found a significant decrease in regional activity at P<0.05 after Bonferroni correction in the left thalamus, right amygdala, right hippocampus, left ventral striatum and the right dorsal striatum. Decreases in the left thalamus, left dorsal striatum and the subgenual cingulate were correlated with a reduction in depression scores (P<0.05 after Bonferroni correction). Placebo treatment was associated with a significant decrease in activity only in the right amygdala, and no region had a change in activity that was correlated with change in depression scores. The groups differed significantly in the relationship between the changes in depression scores and in activity in the thalamus bilaterally and the left ventral striatum. The findings provide evidence that administration of supraphysiologic thyroid hormone improves depressive symptoms in patients with bipolar disorder by modulating function in components of the anterior limbic network.

Personal factors in systemic sclerosis and their coverage by patient-reported outcome measures. A multicentre European qualitative study and literature review.

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.

Prediction of antidepressant response to venlafaxine by a combination of early response assessment and therapeutic drug monitoring.

INTRODUCTION: Early assessment of a therapeutic response is a central goal in antidepressant treatment. The present study examined the potential for therapeutic drug monitoring and symptom rating to predict venlafaxine treatment efficacy (measured by overall patient response and remission). METHODS: 88 patients were uptitrated homogenously to 225 mg/day venlafaxine. Serum concentrations of venlafaxine (VEN) and its active metabolite O-desmethylvenlafaxine (ODV) were measured at week 2. Continuous psychopathometric ratings were measured for up to 6 weeks by independent study raters. RESULTS: An early improvement was significantly more common in venlafaxine responders than non-responders (χ(2); p=0.007). While ODV serum levels were significantly higher in responders (t test; p=0.006), VEN serum levels, sum level of VEN+ODV and the ratio of ODV/VEN levels were not. Moreover, patients who showed an early response combined with an ODV serum level above the median of 222 ng/mL were significantly more likely to achieve full response (binary logistic model; p<0.01). Sensitivity (84% for early response) and specificity (81% for combination of early response and therapeutic drug monitoring) were sufficient to qualify as a reasonable screening instrument. CONCLUSION: Our results indicate that early improvement and ODV serum concentration are predictive of therapeutic outcome and can thus be used to guide use of the antidepressant venlafaxine.

Influence of levothyroxine in augmentation therapy for bipolar depression on central serotonergic function.

INTRODUCTION: Adjunctive treatment with supraphysiological doses of levothyroxine (L-T4) in bipolar depression shows promise, but the neurobiological mechanisms underlying clinical improvement are unknown. It has been postulated from animal studies that exogenous thyroid hormones may exert their modulatory effects in patients with affective disorders via an increase in serotonergic neurotransmission. Therefore, we investigated the loudness dependence of auditory evoked potentials (LDAEP) as a measure of central serotonergic activity and response to L-T4. METHODS: This 6-week, double-blind, randomized, placebo-controlled study assessed the efficacy of L-T4 adjunctive to continuing treatment with mood stabilizer and/or antidepressant medication in 20 patients with bipolar depression. LDAEP was assessed before and after treatment with L-T4. RESULTS: Scores of the Hamilton Depression Rating Scale and Montgomery Asberg Depression Rating Scale decreased significantly during the study. There was no difference in pre- and post-treatment LDAEP between the groups, and no correlation between LDAEP and psychometric measures in the course of the study. DISCUSSION: The hypothesis of a relationship between response of augmentation therapy with levothyroxine in bipolar depression and serotonergic activity could not be confirmed.

Do rehabilitation tools cover the perspective of patients with rheumatoid arthritis? A focus group study using the ICF as a reference.

BACKGROUND: Despite the advocated use of rehabilitation tools in clinical rehabilitation of with rheumatoid arthritis (RA) patients, little is known about the representation of the patient perspective in these tools. AIM: Aim of the study was to explore the experiences of RA patients with rehabilitation and the coverage by rehabilitation tools. DESIGN AND POPULATION: Qualitative focus group study with RA patients about experiences with rehabilitation. SETTING: Rheumatology rehabilitation clinic of a Dutch university hospital. METHODS: Focus groups were tape recorded and transcribed verbatim. From the meaningful units, concepts were extracted and linked to the International Classification of Functioning, Disability and Health (ICF). Rehabilitation tools validated for RA were identified using a structured literature search. Using the ICF as common framework, we determined for each concept identified in the focus groups the coverage by each rehabilitation tool. RESULTS: Nineteen patients participated in 4 focus groups. Fifty-one concepts were identified in 368 meaningful units derived from the transcribed data. From the literature the ICF Core Sets for RA, Canadian Occupational Performance Measure, Rehabilitation Activities Profile and WHO Disability Assessment Schedule II were elected. The concepts from the focus groups were best covered by the ICF Core Sets (44 out of 51; 86%), followed by the WHODAS II (39%), RAP (35%) and COPM (16%). CONCLUSION: With the exception of the ICF Core Sets for RA, current rehabilitation tools poorly cover the RA patients' perception on rehabilitation. CLINICAL REHABILITATION IMPACT: The ICF Core Sets can serve as a checklist to guide multidisciplinary assessment, goal-setting and evaluation in RA rehabilitation.

A physiotherapy-directed occupational health programme for Austrian school teachers: a cluster randomised pilot study.

BACKGROUND: Although physiotherapists have long advocated workplace health, school teachers have not traditionally been a focus of study by these professionals. However, classroom teaching contributes to a range of occupational health issues related to general health as well as ergonomics that can be prevented or addressed by physiotherapists. OBJECTIVES: To undertake a pilot study to explore the potential effects of a physiotherapy-directed occupational health programme individualised for school teachers, develop study methodology and gather preliminary data to establish a 'proof of concept' to inform future studies. DESIGN: Cluster randomised pilot study using a convenience sample. SETTING: Eight Austrian regional secondary schools. PARTICIPANTS: Schools and their teachers were recruited and allocated to an intervention group (IG, n=26 teachers) or a control group (CG, n=43 teachers). Teachers were eligible to participate if they reported no health issues that compromised their classroom responsibilities. INTERVENTIONS: The IG participated in an individualised physiotherapy-directed occupational health programme (six 30-minute sessions) related to ergonomics and stress management conducted over a 5-month semester. The CG had a pseudo-intervention of one oral education session. MAIN OUTCOME MEASURES: Primary outcomes included scores from the physical and mental components and health transition item of the Short-Form-36 Health Survey questionnaire (SF-36), and emotional well-being and resistance to stress items from the work-related behaviour and experience patterns questionnaire. Data were collected before and after one semester. RESULTS: The primary outcome measure, the SF-36 physical component score, showed a reduction in the CG and no change in the IG, meaning that the CG deteriorated over the study semester while the IG did not show any change. CONCLUSIONS: A physiotherapy-directed occupational health programme may prevent deterioration of physical health of school teachers in one semester (proof of concept). This pilot study provided valuable information to inform the design of replication and extension studies related to this work.

Depression with psychotic features is influenced by the polymorphism of the serotonin transporter gene.

INTRODUCTION: Current diagnostic classifications regard psychotic symptoms during depressive episodes as indicators of depression severity. However, growing evidence suggests that depression with psychotic symptoms (MDP) may represent a distinct subtype of depression. In the course of the search for discriminating factors we tested the hypothesis that the serotonin transporter gene (5-HTTLPR) may interact with the manifestation of psychotic symptoms in acute depression. METHODS: 112 inpatients (61 female) with a depressive episode (16 bipolar, 86 unipolar) at admission were genotyped for 5-HTTLPR variants. Psychotic symptoms und general psychopathology were evaluated comprehensively using the Manual of the Association for Methodology and Documentation in Psychiatry (Arbeitsgemeinschaft für Methodik und Dokumentation in der Psychiatrie, 1981). For statistical analysis a chi-square test and a logistic regression model was used. RESULTS: 16 (14.3%) out of 112 patients were currently presenting with psychotic symptoms. The primary finding of our study was the higher prevalence of the s-allele of the 5-HTTLPR within the group of MDP patients (Pearson χ²=7.87; df=2; p<0.03). Secondly, in a logistic regression model, 5-HTTLPR was found to significantly contribute to the diagnosis of MDP (χ²=6.5; df=1; p=0.01). This effect was even more pronounced upon comparing only severely depressed patients with MDP patients. From a psychopathological perspective, MDP patients showed higher AMDP hostility and apathy scores but equal AMDP depression scores. DISCUSSION: This is the first study to show an influence of 5-HTTLPR on psychotic symptoms in acutely depressed patients. LIMITATIONS: The lack of a control group and the relatively small sample size limits the present study's findings, thus replication in a larger sample is necessary.

Uncertainty and opportunities in patients with established systemic lupus erythematosus: a qualitative study.

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.

Life stories of people with rheumatoid arthritis who retired early: how gender and other contextual factors shaped their everyday activities, including paid work.

OBJECTIVE: The aim of the present study was to explore how contextual factors affect the everyday activities of women and men with rheumatoid arthritis (RA), as evident in their life stories. METHODS: Fifteen people with RA, who had retired early due to the disease, were interviewed up to three times, according to a narrative biographic interview style. The life stories of the participants, which were reconstructed from the biographical data and from the transcribed 'told story' were analysed from the perspective of contextual factors, including personal and environmental factors. The rigour and accuracy of the analysis were enhanced by reflexivity and peer-review of the results. RESULTS: The life stories of the participants in this study reflected how contextual factors (such as gender, the healthcare system, the support of families and social and cultural values) shaped their everyday activities. In a society such as in Austria, which is based on traditional patriarchal values, men were presented with difficulties in developing a non-paid-work-related role. For women, if paid work had to be given up, they were more likely to engage in alternative challenging activities which enabled them to develop reflective skills, which in turn contributed to a positive and enriching perspective on their life stories. Health professionals may thus use some of the women's strategies to help men. CONCLUSION: Interventions by health professionals in people with RA may benefit from an approach sensitive to personal and environmental factors.
