Prüfung des Eskalationsmodells (Art. 6 und 7 EpG) unter besonderer Berücksichtigung der Epidemiologie übertragbarer Krankheiten sowie Public-Health-Aspekten : Thesenpapier im Auftrag des Bundesamtes für Gesundheit (BAG) im Rahmen der Revision des Epidemiengesetzes (EpG)

Das aktuelle Epidemiengesetz (EpG) definiert ein dreistufiges Eskalationsmodell, welches neben der normalen Lage eine besondere und eine ausserordentliche Lage vorsieht. Ziel dieses Eskalationsmodells ist es, die Zuständigkeiten von Bund und Kantonen zu klären und zweckmässige Massnahmen zur Bekämpfung von übertragbaren Krankheiten in Abhängigkeit der epidemiologischen Lage vorzusehen. In diesem Thesenpapier unterziehen wir die Anwendung und Umsetzung des Eskalationsmodells seit der Einführung am 1. Januar 2016 einer kritischen Prüfung, mit einem spezifischen Fokus auf der COVID-19-Pandemie

Postoperative radiotherapy for meningiomas - a decision-making analysis.

BACKGROUND The management of meningiomas is challenging, and the role of postoperative radiotherapy is not standardized. METHODS Radiation oncology experts in Swiss centres were asked to participate in this decision-making analysis on the use of postoperative radiotherapy (RT) for meningiomas. Experts from ten Swiss centres agreed to participate and provided their treatment algorithms. Their input was converted into decision trees based on the objective consensus methodology. The decision trees were used as a basis to identify consensus and discrepancies in clinical routine. RESULTS Several criteria used for decision-making in postoperative RT in meningiomas were identified: histological grading, resection status, recurrence, location of the tumour, zugzwang (therapeutic need to treat and/or severity of symptoms), size, and cell division rate. Postoperative RT is recommended by all experts for WHO grade III tumours as well as for incompletely resected WHO grade II tumours. While most centres do not recommend adjuvant irradiation for WHO grade I meningiomas, some offer this treatment in recurrent situations or routinely for symptomatic tumours in critical locations. The recommendations for postoperative RT for recurrent or incompletely resected WHO grade I and II meningiomas were surprisingly heterogeneous. CONCLUSIONS Due to limited evidence on the utility of postoperative RT for meningiomas, treatment strategies vary considerably among clinical experts depending on the clinical setting, even in a small country like Switzerland. Clear majorities were identified for postoperative RT in WHO grade III meningiomas and against RT for hemispheric grade I meningiomas outside critical locations. The limited data and variations in clinical recommendations are in contrast with the high prevalence of meningiomas, especially in elderly individuals

A Vaccine against Nicotine for Smoking Cessation: A Randomized Controlled Trial

BACKGROUND: Tobacco dependence is the leading cause of preventable death and disabilities worldwide and nicotine is the main substance responsible for the addiction to tobacco. A vaccine against nicotine was tested in a 6-month randomized, double blind phase II smoking cessation study in 341 smokers with a subsequent 6-month follow-up period. METHODOLOGY/PRINCIPAL FINDINGS: 229 subjects were randomized to receive five intramuscular injections of the nicotine vaccine and 112 to receive placebo at monthly intervals. All subjects received individual behavioral smoking cessation counseling. The vaccine was safe, generally well tolerated and highly immunogenic, inducing a 100% antibody responder rate after the first injection. Point prevalence of abstinence at month 2 showed a statistically significant difference between subjects treated with Nicotine-Qbeta (47.2%) and placebo (35.1%) (P = 0.036), but continuous abstinence between months 2 and 6 was not significantly different. However, in subgroup analysis of the per-protocol population, the third of subjects with highest antibody levels showed higher continuous abstinence from month 2 until month 6 (56.6%) than placebo treated participants (31.3%) (OR 2.9; P = 0.004) while medium and low antibody levels did not increase abstinence rates. After 12 month, the difference in continuous abstinence rate between subjects on placebo and those with high antibody response was maintained (difference 20.2%, P = 0.012). CONCLUSIONS: Whereas Nicotine-Qbeta did not significantly increase continuous abstinence rates in the intention-to-treat population, subgroup analyses of the per-protocol population suggest that such a vaccination against nicotine can significantly increase continuous abstinence rates in smokers when sufficiently high antibody levels are achieved. Immunotherapy might open a new avenue to the treatment of nicotine addiction. TRIAL REGISTRATION: Swiss Medical Registry 2003DR2327; ClinicalTrials.gov NCT00369616

Oncoplastic breast consortium recommendations for mastectomy and whole breast reconstruction in the setting of post-mastectomy radiation therapy

Aim: Demand for nipple-and skin-sparing mastectomy (NSM/SSM) with immediate breast reconstruction (BR) has increased at the same time as indications for post-mastectomy radiation therapy (PMRT) have broadened. The aim of the Oncoplastic Breast Consortium initiative was to address relevant questions arising with this clinically challenging scenario. Methods: A large global panel of oncologic, oncoplastic and reconstructive breast surgeons, patient advocates and radiation oncologists developed recommendations for clinical practice in an iterative process based on the principles of Delphi methodology. Results: The panel agreed that surgical technique for NSM/SSM should not be formally modified when PMRT is planned with preference for autologous over implant-based BR due to lower risk of long-term complications and support for immediate and delayed-immediate reconstructive approaches. Nevertheless, it was strongly believed that PMRT is not an absolute contraindication for implant-based or other types of BR, but no specific recom-mendations regarding implant positioning, use of mesh or timing were made due to absence of high-quality evidence. The panel endorsed use of patient-reported outcomes in clinical practice. It was acknowledged that the shape and size of reconstructed breasts can hinder radiotherapy planning and attention to details of PMRT techniques is important in determining aesthetic outcomes after immediate BR. Conclusions: The panel endorsed the need for prospective, ideally randomised phase III studies and for surgical and radiation oncology teams to work together for determination of optimal sequencing and techniques for PMRT for each patient in the context of BRPeer reviewe

Early palliative care integration trial: consultation content and interaction dynamics.

OBJECTIVES Evidence for the positive impact of the early integration of palliative care (EPC) continues to grow. Less is known about how EPC improves patient and family outcomes, including the content of EPC consultations. Therefore, we aimed to better understand the content of EPC consultations including areas addressed, percentage covered per area and interaction style. METHODS As part of a trial in which EPC in addition to oncology care was compared with oncology care alone, we audio recorded 10 interventions. The palliative care team led the interventions using SENS, a conversation structure, which stands for: Symptoms, End-of-life decision-making, Network and Support. We employed two approaches to analysis: the Roter interaction analysis system (RIAS) to analyse interaction dynamics and SENS as a framework for content analysis. RESULTS Physician-patient communication covered 91% of the interaction. According to RIAS, the consultations were evenly dominated between physicians and patients (ratio=1.04) and highly patient-centred (ratio=1.26). Content wise, rapport was the largest category covering 27% of the consultation, followed by decision-making (21%) and by symptom assessment/management (17%) including 8.1% for physical symptoms and 5.4% for psychosocial aspects. Network discussions covered 17%, and lastly, support for the family 7%. CONCLUSIONS EPC consultations cover a variety of end-of-life topics while putting a high value in establishing rapport, developing a relationship with patients, and on providing reassurance and positive emotional talk. EPC consultations using predefined structures may guarantee that a minimum of important aspects are addressed in a way in which the relationship with the patient remains at the centre

Machine Learning for the Detection and Segmentation of Benign Tumors of the Central Nervous System: A Systematic Review

Objectives: To summarize the available literature on using machine learning (ML) for the detection and segmentation of benign tumors of the central nervous system (CNS) and to assess the adherence of published ML/diagnostic accuracy studies to best practice. Methods: The MEDLINE database was searched for the use of ML in patients with any benign tumor of the CNS, and the records were screened according to PRISMA guidelines. Results: Eleven retrospective studies focusing on meningioma (n = 4), vestibular schwannoma (n = 4), pituitary adenoma (n = 2) and spinal schwannoma (n = 1) were included. The majority of studies attempted segmentation. Links to repositories containing code were provided in two manuscripts, and no manuscripts shared imaging data. Only one study used an external test set, which raises the question as to whether some of the good performances that have been reported were caused by overfitting and may not generalize to data from other institutions. Conclusions: Using ML for detecting and segmenting benign brain tumors is still in its infancy. Stronger adherence to ML best practices could facilitate easier comparisons between studies and contribute to the development of models that are more likely to one day be used in clinical practice

Feelings of Burden in Palliative Care: A Qualitative Analysis of Medical Records

Background: Care for palliative care patients is often provided by unpaid caregivers (e.g. family members) who take care of the patient’s daily needs (e.g. bathing, dressing). Family members of palliative care patients are involved in numerous ways. These tasks and responsibilities can make them feel burdened and even overburdened. Aim: We specifically looked at patients’ medical records to determine what is being reported about burden and overburden and who seems to be mostly affected. Burden was understood as a weight or task that is difficult to accept or carry, whereas overburden indicates that this weight or task cannot be carried anymore. Methods: We looked at 300 medical records of palliative care patients written by healthcare professionals. Written notes were analysed using latent content analysis as it helps to analyse large amounts of textual data qualitatively and to understand the underlying concepts of what was said. Results: Most patients (73.5%) had a cancer diagnosis. Mean age was 67.6 years (range 22 to 98 years). Burden and overburden were identified as main categories and further divided into the following sub-categories: for patients and families. According to the written notes, patients often felt burdened by their disease, financial problems, situation at home and families’ reactions to their disease. By and large, patients felt overburdened by their own disease. Families often felt burdened because of issues related to patients’ medical condition, providing home care or financial and social aspects. Families mentioned homecare and the decision-making process as being overburdening. Conclusion: Findings in the palliative care patients’ medical records are inasmuch important, as they point at the healthcare staff’s awareness of possible weights and tasks that might be burdensome for patients and their families. Attention should be drawn to the documentation of medical records in order to identify recurrent difficulties and to help discuss these
