Predictors of cancer patients' utilization of psychooncological support: Examining patient´s attitude and physician´s recommendation.

PURPOSE: Patients with cancer suffer from a wide range of psychological distress. Nevertheless, in the literature low utilization rates of psychooncological services are reported. Various factors may influence the utilization of professional support during inpatient care. Up to now it is unclear to what extent patients' attitude towards psychooncological support and physicians' recommendation for psychooncological care may influence the utilization. METHODS: In a multicenter longitudinal observational study in Comprehensive Cancer Centers Germany, 1398 patients with mixed cancer diagnoses were assessed at baseline during their hospital stay with respect to psychooncological distress and the need for and use of psychooncological services. RESULTS: Psychooncological support was used by almost 28.4% of patients up to this time. A positive attitude towards psychooncological support was reported by 41.6%. A recommendation of psychooncological support by a physician was received by 16.2%. These patients reported a significant higher level of distress compared to patients who did not received a recommendation. Multivariable logistic regression detected that the utilization rate was 3.79 times higher among patients with positive attitude towards psychooncological support (OR, 3.79; 95% CI 2.51-5.73, p < 0.001). Utilization was 4.21 times more likely among patients who received a physician´s recommendation (OR, 4.21; 95% CI 2.98-5.95, p < 0.001). CONCLUSION: The results of the study provide evidence of the relevance of giving more attention to psychooncological distress and attitudes towards psychooncological care. To reduce reservations, patients need low-threshold information about the psychooncological services offered.

Identification of the Needs and Preferences of Patients With Cancer for the Development of a Clinic App: Qualitative Study.

BACKGROUND: Mobile health (mHealth) tools were developed during the past decades and are increasingly used by patients in cancer care too. Scientific research in the development of mHealth services is required in order to meet the various needs of patients and test usability. OBJECTIVE: The aim of this study is to assess patients' needs, preferences, and usability of an app (My University Clinic [MUC] app) developed by the Comprehensive Cancer Center Freiburg (CCCF) Germany. METHODS: Based on a qualitative cross-sectional approach, we conducted semistructured interviews with patients with cancer, addressing their needs, preferences, and usability of the designed MUC app. Patients treated by the CCCF were recruited based on a purposive sampling technique focusing on age, sex, cancer diagnoses, and treatment setting (inpatient, outpatient). Data analysis followed the qualitative content analysis according to Kuckartz and was performed using computer-assisted software (MAXQDA). RESULTS: For the interviews, 17 patients with cancer were selected, covering a broad range of sampling parameters. The results showed that patients expect benefits in terms of improved information about the disease and communication with the clinic staff. Demands for additional features were identified (eg, a list of contact persons and medication management). The most important concerns referred to data security and the potential restriction of personal contacts with health care professionals of the clinical departments of the CCCF. In addition, some features for improving the design of the MUC app with respect to usability or for inclusion of interacting tools were suggested by the patients. CONCLUSIONS: The results of this qualitative study were discussed within the multidisciplinary team and the MUC app providers. Patients' perspectives and needs will be included in further development of the MUC app. There will be a second study phase in which patients will receive a test version of the MUC app and will be asked about their experiences with it.

Caring for dependent children impacts practical and emotional problems and need for support, but not perceived distress among cancer patients.

OBJECTIVE: More than one in 10 cancer patients care for dependent children. It is unclear whether this status makes a difference in terms of the distress and associated problems they experience, or whether it is linked to differences in the need for or utilization of psychosocial support. METHODS: Secondary analysis of a cross-sectional German study in National Comprehensive Cancer Centers using self-report standardized questionnaires administered to inpatients. Patients living with dependent children (n = 161) were matched by age and sex with a subsample of 161 cancer patients not living with dependent children. The resulting sample was tested for between-group differences in Distress Thermometer (DT) scores and the corresponding DT Problem List. Additionally, between-group differences in measures of the need for and utilization of psychosocial support were examined. RESULTS: More than 50% of all patients suffered from clinically relevant distress. Patients living with dependent children reported significantly more practical (p < 0.001, η2 p = 0.04), family (p < 0.001, η2 p = 0.03), and emotional problems (p < 0.001, η2 p = 0.01). Although reporting a greater need for psychological support, parents with cancer were not found to more frequently utilize any type of psychosocial support. CONCLUSIONS: The specific problems and needs of parents with cancer who care for dependent children are currently not sufficiently addressed in the clinical care pathways. All families should be helped to establish open and honest communication as well as understand the available support systems and what they can provide. Tailored interventions should be implemented for highly distressed families.

[Need for Further Training for Function Holders of Cancer Self-Help Organizations]. / Bedarf an Fortbildung für Funktionsträger*innen von Krebs-Selbsthilfeorganisationen.

OBJECTIVE: As part of the Center for Competence Development in Cancer Self-Help at the University Medical Center Freiburg, an analysis of the need for training and education was conducted among the member organizations of the House of the Cancer Patient Support Associations of Germany (HKSH). METHODS: The online survey took place from February to April 2021 and was completed by functionaries at various organization levels and group members. In a questionnaire developed together with self-help representatives 19 potential training topics were ranked in terms of importance. In addition, it was indicated whether the respective topic was perceived as sufficiently covered by already existing qualification offers. Using a forced-choice approach, respondents finally named the five most important topics for them. RESULTS: The topics that a particularly high proportion of the N=293 respondents identified as "very important" and which at the same time were perceived as inadequately addressed by existing qualification offers were dealing with stressful issues (e. g. relapse, metastases, dying), recruiting new members and successors for association tasks, socio-legal aspects, as well as conversational and communication skills. In the prioritization of the five most important topics, the first three topics were named again, with dealing with excessive demands and assistance for self-care/burnout prevention following in fourth place and in the fifth place the topics of knowledge in dealing with complementary medicine and knowledge of professional care structures in oncology, each with the same number of votes. DISCUSSION: There was a clear need for a broad range of training topics that goes beyond the existing offers of the cancer self-help organizations. Through the needs analysis, the topics could be identified which are prioritized as training topics across all ten member organizations of the HKSH. CONCLUSION: Based on this needs assessment, the respective training courses can be prioritized and implemented in cooperation with the patient representatives of the HKSH.

Utilisation of complementary medicine in cancer patients and survivors: Expected benefits and its association to psychosocial factors.

INTRODUCTION: Previous research showed that various factors are associated with the use of complementary medicine (CM) in cancer patients. This study aimed to analyse the expected benefits of CM use in its association with medical, sociodemographic and psychosocial variables. METHODS: In a cross-sectional survey, we assessed the use of CM, expected benefits of CM, depression and quality of life. An exploratory factor analysis (EFA) was performed. Multiple regression analysis was carried out with the factors derived from the EFA as dependent variables. RESULTS: Based on 292 cancer CM user, EFA revealed two factors: a supportive effect (SPE) and an antitumoral effect (ATE). In the multiple regression analysis, reduced emotional functioning and the diagnosis of breast cancer are associated with the higher expectation of a supportive effect of CM (p < 0.001), explaining 7.1% of the variance. Emotional functioning, educational level and metastases are associated with higher expectation of an antitumoral effect of CM (p < 0.001) and explained 14.8% of the variance. DISCUSSION: This study provides evidence that two overall domains (supportive effect and anti-tumoural effect) characterise the benefits of CM expected by cancer patients. Psychosocial and medical variables are associated with both domains, but explain only small proportion of the variance.

Return to work after cancer: Improved mental health in working cancer survivors.

OBJECTIVE: Aim of the study was to compare working and non-working patients over a period of 12 months regarding socio-demographic, cancer-specific and mental health parameters. METHODS: This study was conducted as part of a Germany-wide longitudinal survey among 1398 patients in 13 national Comprehensive Cancer Centers. The sample used for analysis consisted of n = 430 cancer patients younger than 65 years (age M = 52.4 years, SD = 8.1; 67.0% females). Socio-demographic, cancer-specific and mental health parameters (Depression: Patient Health Questionnaire, Anxiety: Generalized Anxiety Disorder Scale, Distress: Distress Thermometer) were assessed at baseline during hospitalization and at 12 months follow-up. RESULTS: 73.7% of all patients (n = 317) have returned to work after one year. While working and non-working patients did not differ in socio-demographic parameters, there were significant differences in the presence of metastases, tumor and treatment status. Mixed analysis of variances revealed significant interactions between working status and time for depression (p = 0.009), anxiety (p = 0.003) and distress (p = 0.007). Non-working patients reported higher levels of depression, anxiety and distress than working patients over time. A logistic regression showed significant associations between lower depression (p = 0.019), lower distress (p = 0.033) and the absence of a tumor (p = 0.015) with working status. CONCLUSIONS: The majority of cancer survivors returned to work. Non-working patients had higher levels of depression, anxiety and distress than working patients. After controlling for cancer-specific factors, mental health parameters were still independently associated with working status. Return to work can thus be associated with an improved mental health in cancer survivors. In order to establish causality, further research is necessary.

Defining Criteria for Guiding Cancer Patients to Find a Reputable Complementary Medicine Provider: Results of a Literature Review and a Consensus Procedure.

PURPOSE: Even in cases of positive evidence for complementary medicine (CM) therapies, it is still difficult for cancer patients to identify reputable providers. The aim of this study was to develop and evaluate a criteria list to provide guidance to cancer patients seeking a reputable CM provider. METHODS: The design combined a literature review, an expert consensus procedure (n=15) and an assessment from three stakeholder perspectives (patients (n=18), CM providers (n=26) and oncology physicians (n=20)). RESULTS: A total of 30 existing CM criteria were extracted from the literature, and 12 more were added by the experts. The main challenge was to define criteria that could easily be applied by the patients. A final comprehensive list of 8 criteria guiding cancer patients to find a reputable CM provider was developed. CONCLUSION: Health professionals and cancer information services might find the criteria list helpful when aiming to strengthen patients' awareness of quality-related factors associated with CM providers. The criteria developed might be helpful when standards are established for quality assurance in CM in oncology.

Educational Program in Complementary and Alternative Medicine for Cancer Self-Help Groups.

BACKGROUND: The use of complementary and alternative medicine (CAM) among cancer patients is estimated to be approximately 40%. In self-help groups there is a need for information about CAM. This pilot study aimed to develop and evaluate a CAM educational program for cancer self-help groups. METHODS: The educational program was developed in cooperation with health professionals and representatives of cancer self-help organizations. Participants were trained to increase their knowledge about CAM, to reflect their user behavior, and to use evidence-based information. Self-help group leaders were educated along the curriculum and motivated to carry out the course in their groups. Using questionnaires it was evaluated in terms of acceptance, feasibility, and satisfaction by participants. RESULTS: A total of 171 self-help group leaders were educated. In a pilot run 7 implemented the course in their groups, with a total of 70 participants. Most of them (n = 60, 85.7%) appreciated its contents and material and would recommend it. Overall acceptance and satisfaction were high. CONCLUSIONS: The educational program was implemented successfully in a small sample and showed positive results for acceptance and feasibility. In addition to consultation by experts, it can be a good option to inform cancer survivors about CAM.

KOKON: A Germany-Wide Collaborative Research Project to Identify Needs, Provide Information, Foster Communication and Support Decision-Making about Complementary and Alternative Medicine in Oncology.

BACKGROUND: The German Cancer Aid set up a priority research programme with the intention to generate high-quality information based on evidence and to make this information easily accessible for health-care professionals and advisors, researchers, patients, and the general public. SUMMARY: The Kompetenznetz Komplementärmedizin in der Onkologie (KOKON) received 2 funding periods within this programme. During the first funding period, KOKON assessed patients' and health-care professionals' informational needs, developed a consulting manual for physicians, developed an education programme for self-help groups, set up a knowledge database, and developed a pilot information website for patients. Funding period 2 continues with work that allows cancer patients and health-care professionals to make informed decisions about complementary and alternative medicine (CAM). For this aim, KOKON evaluates training programmes for physicians (oncology physicians, paediatric oncologists, and general practitioners) and for self-help groups. All training programmes integrate results from an analysis of the ethical, psychological, and medical challenges of CAM in the medical encounter, and the knowledge database is being extended with issues related to CAM for supportive and palliative care. Key Message: A Germany-wide collaborative research project to identify needs, provide information, foster communication, and support decision-making about CAM in oncology is being set up.

Impact of social support on psychosocial symptoms and quality of life in cancer patients: results of a multilevel model approach from a longitudinal multicenter study.

Background: This prospective multicenter study aimed to investigate the courses of positive support (PS) and detrimental interaction (DI), two different aspects of social support, and the relation between social support and psychosocial distress and/or health-related quality of life (HRQOL) in a large sample of patients with different cancers. Methods: For this observational study, we enrolled adult patients with cancer from 13 comprehensive cancer centers (CCCs) in Germany. We included a total of 1087 patients in our analysis. We assessed the outcomes via standardized self-report questionnaires at three measurement points: at admission for acute care (T1), 6 (T2) and 12 months (T3) thereafter. Our outcome variables included PS and DI, depression and anxiety symptoms, distress, mental quality of life (MQoL) and physical QoL (PQoL). Data were analyzed using three-level hierarchical linear modeling (HLM) and group-based trajectory modeling. Results: During the first year after the cancer diagnosis, both PS and DI decreased in our sample. Baseline depression symptom severity was a significant predictor of PS and DI. Further analyses revealed significant associations between PS, DI and the course of depression and anxiety symptoms, and MQoL. PS buffered the negative effects of DI with regards to these variables. Low DI was associated with better PQoL, whereas PS was not. In general, the impact of social support on psychosocial outcomes was weak to moderate. Conclusions: Our findings provide evidence for the influence of PS and DI on psychosocial symptoms and HRQOL, and emphasize the importance of psycho-oncological interventions that strengthen PS and prevent or reduce DI for patients with cancer and their relatives.

Psychosocial distress and utilization of professional psychological care in cancer patients: An observational study in National Comprehensive Cancer Centers (CCCs) in Germany.

OBJECTIVE: The study aimed to assess cancer patients' use of psychological care and its correlates in a large sample of cancer patients in Comprehensive Cancer Centers (CCCs) in Germany. METHODS: In a multicenter study in Germany, cancer patients with various diagnoses were evaluated for self-reported use of psychological support. We measured psychological distress, depression and anxiety, quality of life, and social support with standardized questionnaires and analyzed its association with the utilization of psychological care using multivariable logistic regression. This paper focuses on a cross-sectional analysis of the data assessed during inpatient care. RESULTS: Three thousand fifty-four (50%) of hospitalized patients were asked for participation, and n = 1632 (53.6%) participated. We were able to analyze n = 1,398 (45.9%) patients. Three hundred ninety-seven (28.4%) of the sample utilized psychological support. Users of psychological care were significantly younger than nonusers (odds ratio [OR]: 0.967, P < 0.001) and were more often female (OR: 1.878, P < 0.001), whereas educational level was not associated with the use of psychological care. In the multivariable analysis, effects on the use of psychological care were observed for Hospital Anxiety and Depression Scale (HADS) anxiety (OR: 1.106, P = 0.001) and both subscales of the 12-item Short Form Health Survey (SF-12) quality of life measure (mental, OR: 0.97, P = 0.002; physical, OR: 0.97, P = 0.002). CONCLUSION: Psychological distress and anxiety are higher, and quality of life is lower in users of psychological care in comparison with nonusers during inpatient cancer treatment. Although psychooncological services should be provided to all patients who need them, special efforts should be made to reach populations that report low utilization.

Kinetics of ventilation-induced changes in diaphragmatic metabolism by bilateral phrenic pacing in a piglet model.

Perioperative necessity of deep sedation is inevitably associated with diaphragmatic inactivation. This study investigated 1) the feasibility of a new phrenic nerve stimulation method allowing early diaphragmatic activation even in deep sedation and, 2) metabolic changes within the diaphragm during mechanical ventilation compared to artificial activity. 12 piglets were separated into 2 groups. One group was mechanically ventilated for 12 hrs (CMV) and in the second group both phrenic nerves were stimulated via pacer wires inserted near the phrenic nerves to mimic spontaneous breathing (STIM). Lactate, pyruvate and glucose levels were measured continuously using microdialysis. Oxygen delivery and blood gases were measured during both conditions. Diaphragmatic stimulation generated sufficient tidal volumes in all STIM animals. Diaphragm lactate release increased in CMV transiently whereas in STIM lactate dropped during this same time point (2.6 vs. 0.9 mmol L-1 after 5:20 hrs; p < 0.001). CMV increased diaphragmatic pyruvate (40 vs. 146 µmol L-1 after 5:20 hrs between CMV and STIM; p < 0.0001), but not the lactate/pyruvate ratio. Diaphragmatic stimulation via regular electrodes is feasible to generate sufficient ventilation, even in deep sedation. Mechanical ventilation alters the metabolic state of the diaphragm, which might be one pathophysiologic origin of ventilator-induced diaphragmatic dysfunction. Occurrence of hypoxia was unlikely.

[Beweggründe von Krebspatienten für und gegen die Inanspruchnahme der Misteltherapie].

Einleitung: Die Misteltherapie ist im deutschsprachigen Raum ein häufig angewandtes komplementärmedizinisches Verfahren (KM) in der Onkologie. Diese Studie hatte das Ziel, die Beweggründe für oder gegen eine Inanspruchnahme der Misteltherapie zu untersuchen und Themenfeldern zuzuordnen. Patienten und Methoden: Es wurden qualitative leitfadengestützte Interviews mit Krebspatienten geführt. Der Interviewleitfaden fragte nach der Inanspruchnahme von KM, der Motivation zur Inanspruchnahme, Informationsverhalten und -bedürfnissen zu KM sowie nach der Krebserkrankung. Um die Beweggründe für die Inanspruchnahme oder Nichtinanspruchnahme der Misteltherapie zu verstehen, wurden die Interviews inhaltsanalytisch ausgewertet. Ergebnisse: Insgesamt wurden Interviews mit 88 Krebspatienten geführt, davon nutzen 18 (20,5%) die Misteltherapie. Die Beweggründe für oder gegen eine Inanspruchnahme der Misteltherapie ließen sich den 2 Themenfeldern «Wahrgenommene Indikation¼ und «Abwägungen bei der Entscheidungsfindung¼ zuordnen. Diskussion und Schlussfolgerungen: Mit der Misteltherapie wird sowohl ein Einfluss auf das Tumorwachstum als auch eine supportive Wirkung assoziiert. Anwender sehen die Misteltherapie als sicheres Verfahren; Nichtnutzer befürchten eher Neben- oder Wechselwirkungen. Die Empfehlung von Fachpersonal spielt eine wichtige Rolle bei der Inanspruchnahme. Zum Teil waren die Nichtnutzer interessiert an der Anwendung der Misteltherapie, befanden sich jedoch noch im Klärungsprozess.

Perceived need for psychosocial support depending on emotional distress and mental comorbidity in men and women with cancer.

OBJECTIVE: Although elevated levels of distress are supposed to constitute a need for psychosocial support, the relation between elevated distress and need for support does not appear to be straightforward. We aimed to determine cancer patients' perceived need for psychosocial support, and examine the relation of need to both self-reported emotional distress and the interview-based diagnosis of a mental disorder. METHODS: In a multicenter, cross-sectional study in Germany, 4020 cancer patients (mean age 58 years, 51% women) were evaluated. We obtained self-reports of need for psychosocial support. We measured distress with the National Comprehensive Cancer Network (NCCN) Distress Thermometer (DT) and depressive symptoms with the Patient Health Questionnaire (PHQ-9). In a subsample, we evaluated the presence of a mental disorder using the Composite International Diagnostic Interview (CIDI). RESULTS: 32.1% (95%-CI 30.6 to 33.6) of patients perceived a need for psychosocial support. Younger age, female sex, and higher education were associated with more needs, being married and living with a partner with fewer needs, respectively. While up to 51.2% of patients with elevated distress levels reported a need for psychosocial support, up to 26.1% of those without elevated distress levels perceived such a need. Results were similar across distress assessment methods. CONCLUSION: Our findings emphasize that the occurrence of mental distress is one important but not an exclusive factor among different motives to report the need for psychosocial support. We should thus consider multifaceted perspectives, facilitators and barriers when planning and implementing patient-centered psychosocial care services.

[Dance/movement therapy in oncological rehabilitation]. / Tanztherapie in der stationären onkologischen Rehabilitation.

BACKGROUND: Dance/movement therapy may be defined as a psychosocial and body-oriented art therapy, which uses dance for the expression of emotional and cognitive issues. Dance/movement therapy is an important intervention for cancer patients to enhance coping strategies. There are only few studies investigating dance therapy with cancer patients. METHODS: The present study investigates effects of dance/movement therapy (n = 115) in the setting of inpatient rehabilitation based on a pre-post design with a control group as well as a follow-up 3 months later. Standardized questionnaires measuring quality of life, anxiety and depression, and self-concept (EORTC QLQ-C30, HADS, FSKN) were used. In addition, at the end of the inpatient rehabilitation program subjective expectations of the dance/movement therapy and the patients' subjective evaluation of the benefits of the intervention were measured by a new developed questionnaire. RESULTS: As process factors of dance/movement therapy, expression of emotions, enhancement of self-esteem, development of the personality, vitality, getting inner balance, and getting in touch with the body have been identified. In terms of quality of life and psychological well-being, the results showed significant improvements with medium to large effect sizes. CONCLUSIONS: Even though those effects may not be attributed to the intervention alone, the analysis of the data and the patients' subjective statements help to reveal therapeutic factors and process characteristics of dance/movement therapy within inpatient rehabilitation.

The EORTC QLQ-OH17: a supplementary module to the EORTC QLQ-C30 for assessment of oral health and quality of life in cancer patients.

AIMS: Assessment of oral and dental problems is seldom routine in clinical oncology, despite the potential negative impact of these problems on nutritional status, social function and quality of life (QoL). The aim was to develop a supplementary module to the European Organisation for Research and Treatment of Cancer Core Questionnaire (EORTC QLQ-C30) focusing on oral health and related QoL issues in all cancer diagnoses. METHODS: The module development followed the EORTC guidelines. Phases 1&2 were conducted in France, Germany, Greece, Netherlands, Norway and United Kingdom, while seven countries representing seven languages were included in Phase 3. RESULTS: Eighty-five QoL-items were identified from systematic literature searches. Semi-structured interviews with health-care professionals experienced in oncology and oral/dental care (n=18) and patients (n=133) resulted in a provisional module with 41 items. In phase 3 this was further tested in 178 European patients representing different phases of disease and treatment. Results from the interviews, clinical experiences and statistical analyses resulted in the EORTC QLQ-OH17. The module consists of 17 items conceptualised into four multi-item scales (pain/discomfort, xerostomia, eating, information) and three single items related to use of dentures and future worries. CONCLUSION: This study provides a useful tool intended for use in conjunction with the EORTC QLQ-C30 for assessment of oral and dental problems. The increased awareness may lead to proper interventions, thereby preventing more serious problems and negative impact on QoL. The reliability and validity, the cross-cultural applicability and the psychometric properties of the module will be tested in a larger international study.

Chronic augmentation of the parasympathetic tone to the atrioventricular node: a nonthoracotomy neurostimulation technique for ventricular rate control during atrial fibrillation.

INTRODUCTION: The right inferior ganglionated plexus (RIGP) selectively innervates the atrioventricular node. Temporary electrical stimulation of this plexus reduces the ventricular rate during atrial fibrillation (AF). We sought to assess the feasibility of chronic parasympathetic stimulation for ventricular rate control during AF with a nonthoracotomy intracardiac neurostimulation approach. METHODS AND RESULTS: In 9 mongrel dogs, the small endocardial area inside the right atrium, which overlies the RIGP, was identified by 20 Hz stimulation over a guiding catheter with integrated electrodes. Once identified, an active-fixation lead was implanted. The lead was connected to a subcutaneous neurostimulator. An additional dual-chamber pacemaker was implanted for AF induction by rapid atrial pacing and ventricular rate monitoring. Continuous neurostimulation was delivered for 1-2 years to decrease the ventricular rate during AF to a range of 100-140 bpm. Implantation of a neurostimulation lead was achieved within 37 +/- 12 min. The latency of the negative dromotropic response after on/offset or modulation of neurostimulation was <1 s. Continuous neurostimulation was effective and well tolerated during a 1-2 year follow-up with a stimulation voltage <5 V. The neurostimulation effect displayed a chronaxie-rheobase behavior (chronaxie time of 0.07 +/- 0.02 ms for a 50% decrease of the ventricular rate during AF). CONCLUSION: Chronic parasympathetic stimulation can be achieved via a cardiac neurostimulator. The approach is safe, effective, and well tolerated in the long term. The atrioventricular nodal selectivity and the opportunity to adjust the negative dromotropic effect within seconds may represent an advantage over pharmacological rate control.

Implantation and explantation of a wireless epiretinal retina implant device: observations during the EPIRET3 prospective clinical trial.

PURPOSE: Visual sensations in patients with blindness and retinal degenerations may be restored by electrical stimulation of retinal neurons with implantable microelectrode arrays. A prospective trial was initiated to evaluate the safety and efficacy of a wireless intraocular retinal implant (EPIRET3) in six volunteers with blindness and RP. METHODS: The implant is a remotely controlled, fully intraocular wireless device consisting of a receiver and a stimulator module. The stimulator is placed on the retinal surface. Data and energy are transmitted via an inductive link from outside the eye to the implant. Surgery included removal of the lens, vitrectomy, and implantation of the EPIRET3 device through a corneal incision. The clinical outcome after implantation and explantation of the device was determined. The implant was removed after 4 weeks, according to the study protocol. RESULTS: Implantation was successful in all six patients. While the anterior part was fixed with transscleral sutures, the stimulating foil was placed onto the posterior pole and fixed with retinal tacks. The implant was well tolerated, causing temporary moderate postoperative inflammation, whereas the position of the implant remained stable until surgical removal. In all cases explantation of the device was performed successfully. Adverse events were a sterile hypopyon effectively treated with steroids and antibiotics in one case and a retinal break in a second case during explantation requiring silicone oil surgery. CONCLUSIONS: The EPIRET3 system can be successfully implanted and explanted in patients with blindness and RP. The surgical steps are feasible, and the postoperative follow-up disclosed an acceptable range of adverse events.

[Sound meditation in oncological rehabilitation--a pilot study of a receptive music therapy group using the monochord]. / Klangmeditation in der onkologischen Rehabilitation: Pilotstudie zu einer rezeptiven Gruppenmusiktherapie mit dem Monochord.

BACKGROUND: Music therapy can play an important role in psycho-oncology and promote relaxation or coping processes. This pilot study presents an evaluation of receptive music therapy performed in a group at an oncological rehabilitation hospital,with a focus on the experiences made by the patients. PATIENTS AND METHODS: Single-group pre-post study on patients receiving at least 4 sessions of music therapy during a 3-week rehabilitation. A bipolar mood questionnaire was to be filled in by each participant before and after every session of music therapy. In addition, patients answered a questionnaire on quality of life (EORTC QLQ-C30) at the beginning and the end of the whole treatment. Data were analyzed by repeated-measures ANOVA. After the last session, the patients were to answer some open questions in writing. These texts were then analyzed by qualitative content analysis. RESULTS: The data of 105 patients could be analyzed. The mood questionnaire revealed significant changes over the course of the intervention towards feeling more balanced, less nervous and less exhausted. 75.6%of the patients reported positive body sensations such as feelings of heaviness or warmth of limbs during the intervention. CONCLUSIONS: The preliminary results of the pilot study suggest that sound meditation represents an effective relaxation therapy from the beginning of the treatment. In contrast to some other relaxation methods, sound meditation does not require regular exercise or practice to achieve positive effects. Further studies in terms of randomized controlled trials should investigate interactions of different elements of sound meditation with regard to its outcome.
