Down-regulation of the pro-apoptotic XIAP associated factor-1 (XAF1) during progression of clear-cell renal cancer

BACKGROUND: Decreased expression of the interferon-stimulated, putative tumour suppressor gene XAF1 has been shown to play a role during the onset, progression and treatment failure in various malignancies. However, little is yet known about its potential implication in the tumour biology of clear-cell renal cell cancer (ccRCC). METHODS: This study assessed the expression of XAF1 protein in tumour tissue obtained from 291 ccRCC patients and 68 normal renal tissue samples, utilizing immunohistochemistry on a tissue-micro-array. XAF1 expression was correlated to clinico-pathological tumour features and prognosis. RESULTS: Nuclear XAF1 expression was commonly detected in normal renal- (94.1%) and ccRCC (91.8%) samples, without significant differences of expression levels. Low XAF1 expression in ccRCC tissue, however, was associated with progression of tumour stage (p = 0.040) and grade (p < 0.001). Low XAF1 tumour levels were also prognostic of significantly shortened overall survival times in univariate analysis (p = 0.018), but did not provide independent prognostic information. CONCLUSION: These data suggest down-regulation of XAF1 expression to be implicated in ccRCC progression and implies that its re-induction may provide a therapeutic approach. Although the prognostic value of XAF1 in ccRCC appears to be limited, its predictive value remains to be determined, especially in patients with metastatic disease undergoing novel combination therapies of targeted agents with Interferon-alpha

Training in psychosomatic medicine and psychotherapy for medical doctors in China: A field report

BackgroundThe high prevalence rates of mental disorders in China contrast a comparatively low care capacity from qualified trained medical doctors in the mental health field. The main objective of our cooperation project was to develop and implement advanced postgraduate training for medical doctors for their acquisition of knowledge, skills, and attitudes in the field of psychosomatic medicine and psychotherapy in China.MethodsMonitoring and evaluation as part of the advanced training in Beijing were conducted following the Kirkpatrick training approach using four levels of evaluation: reaction, learning, behavior and results. We performed a continuous course evaluation, assessed the respective learning goal attainment, conducted a pre-post evaluation of reasons and goals for participation in the training, and measured the treatment effects on the patient side.ResultsThe implementation of training standards in the field of psychosomatic medicine and psychotherapy for medical doctors and the transfer of didactic knowledge and skills for Chinese lecturers were achieved. A total of 142 mainly medical doctors attended the 2-year training. Ten medical doctors were trained as future teachers. All learning goals were reached. The content and didactics of the curriculum were rated with an overall grade of 1.23 (1 = very good to 5 = very bad). The highest rated elements were patient life interviews, orientation on clinical practice and communication skills training. The achievement of learning objectives for each block (depression, anxiety disorders, somatic symptom disorder, coping with physical diseases) was rated between 1 and 2 (1 = very well achieved to 5 = not achieved) for all items from participants’ perspectives. On the patient side (n = 415), emotional distress decreased and quality of life and the doctor–patient alliance improved significantly.DiscussionAdvanced training in psychosomatic medicine and psychotherapy was successfully implemented. The results of the evaluation show high participant satisfaction and the successful achievement of all learning objectives. A more detailed and extensive evaluation of the data, such as an analysis of the development of the participants as psychotherapists, is in preparation. The continuation of the training under Chinese guidance is guaranteed

Psychosocial primary care – what patients expect from their General Practitioners A cross-sectional trial

BACKGROUND: Psychosocial Primary Care (PPC) is a model of service delivery for patients with mental disorders and psychosocial problems which was established in Germany in 1987. This study was performed as part of the evaluation of a PPC training program. We investigated patients' expectations of the psychosocial treatment offered by GPs trained in PPC. METHODS: Ten general practitioners trained in PPC were randomly selected. Two hundred and twenty patients were surveyed in the waiting room regarding their expectations concerning psychological treatment. RESULTS: Eighty-five per cent of patients could envisage making use of psychosocial treatments. Counselling by the GP was considered most important (65%). Fifty-four per cent of patients indicated that there was sufficient counselling, but further distinctions revealed dissatisfaction with both the extent and content of the counselling. Lack of time was the most frequent reason (53%) cited for insufficient counselling. A willingness to discuss the psychological aspects of illness was exhibited by between 55% (current illness) and 79% of patients. Two-thirds of patients believed that discussing psychological aspects and counselling by the doctor could exert a healing effect or contribute to symptomatic improvement in physical illnesses. Younger patients and patients with experience in psychotherapy expected referral to mental health services. CONCLUSIONS: Primary care patients desire and accept psychological treatment from their GP. Training in psychosocial competence in primary care should be offered more frequently

A European research agenda for somatic symptom disorders, bodily distress disorders, and functional disorders: Results of an estimate-talk-estimate delphi expert study

Background: Somatic Symptom Disorders (SSD), Bodily Distress Disorders (BDD) and functional disorders (FD) are associated with high medical and societal costs and pose a substantial challenge to the population and health policy of Europe. To meet this challenge, a specific research agenda is needed as one of the cornerstones of sustainable mental health research and health policy for SSD, BDD, and FD in Europe. Aim: To identify the main challenges and research priorities concerning SSD, BDD, and FD from a European perspective. Methods: Delphi study conducted from July 2016 until October 2017 in 3 rounds with 3 workshop meetings and 3 online surveys, involving 75 experts and 21 European countries. EURONET-SOMA and the European Association of Psychosomatic Medicine (EAPM) hosted the meetings. Results: Eight research priorities were identified: (1) Assessment of diagnostic profiles relevant to course and treatment outcome. (2) Development and evaluation of new, effective interventions. (3) Validation studies on questionnaires or semi-structured interviews that assess chronic medical conditions in this context. (4) Research into patients preferences for diagnosis and treatment. (5) Development of new methodologic designs to identify and explore mediators and moderators of clinical course and treatment outcomes (6). Translational research exploring how psychological and somatic symptoms develop from somatic conditions and biological and behavioral pathogenic factors. (7) Development of new, effective interventions to personalize treatment. (8) Implementation studies of treatment interventions in different settings, such as primary care, occupational care, general hospital and specialty mental health settings. The general public and policymakers will benefit from the development of new, effective, personalized interventions for SSD, BDD, and FD, that will be enhanced by translational research, as well as from the outcomes of research into patient involvement, GP-patient communication, consultation-liaison models and implementation. Conclusion: Funding for this research agenda, targeting these challenges in coordinated research networks such as EURONET-SOMA and EAPM, and systematically allocating resources by policymakers to this critical area in mental and physical well-being is urgently needed to improve efficacy and impact for diagnosis and treatment of SSD, BDD, and FD across Europe

Gene Expression Profiles of the NCI-60 Human Tumor Cell Lines Define Molecular Interaction Networks Governing Cell Migration Processes

Although there is extensive information on gene expression and molecular interactions in various cell types, integrating those data in a functionally coherent manner remains challenging. This study explores the premise that genes whose expression at the mRNA level is correlated over diverse cell lines are likely to function together in a network of molecular interactions. We previously derived expression-correlated gene clusters from the database of the NCI-60 human tumor cell lines and associated each cluster with function categories of the Gene Ontology (GO) database. From a cluster rich in genes associated with GO categories related to cell migration, we extracted 15 genes that were highly cross-correlated; prominent among them were RRAS, AXL, ADAM9, FN14, and integrin-beta1. We then used those 15 genes as bait to identify other correlated genes in the NCI-60 database. A survey of current literature disclosed, not only that many of the expression-correlated genes engaged in molecular interactions related to migration, invasion, and metastasis, but that highly cross-correlated subsets of those genes engaged in specific cell migration processes. We assembled this information in molecular interaction maps (MIMs) that depict networks governing 3 cell migration processes: degradation of extracellular matrix, production of transient focal complexes at the leading edge of the cell, and retraction of the rear part of the cell. Also depicted are interactions controlling the release and effects of calcium ions, which may regulate migration in a spaciotemporal manner in the cell. The MIMs and associated text comprise a detailed and integrated summary of what is currently known or surmised about the role of the expression cross-correlated genes in molecular networks governing those processes
