SSSPP Position paper: Physical activity and mental health

Promoting physical activity (PA) has not yet been established as a standard procedure in psychiatric care. Psychiatric patients are at higher chance to be physically inactive which contributes to increased morbidity and mortality. Regular PA has shown to improve mental wellbeing in the general population and reduces the risk to develop several mental disorders. Assessing PA and motivation for change should be ­established as routine in psychiatric practice. The recommended dose of exercise for optimal health benefits should be achieved and recommendations on exercise-prescription as well as coaching-programs tailored for mentally ill patients should be developed. Structured exercise therapies should become part of standard psychiatric care. A network of “mental health friendly” sports-clubs could help to facilitate PA for psychiatric populations. Public awareness of mental health benefits of exercise specifically in the prevention of mental disorders is an important topic addressed by the Swiss Society of Sports-Psychiatry and -Psychotherapy. This includes interdisciplinary and interprofessional coordination of efforts to bring more PA into mental health

Physical activity for the treatment and prevention of depression: a rapid review of meta-analyses

Aim: We conducted an umbrella review of 55 meta-analyses to summarize current evidence on the effects of exercise on depression. Results: Aerobic, resistance or combined exercise for several weeks as well as mind-body exercise has shown to yield significant moderate effects on depression severity in adult patients, including the elderly. The effect diminishes when only high-quality studies are analyzed but reaches similar magnitude of other efficacious treatments. Additionally, exercise showed positive effects on sleep, cardiorespiratory fitness and quality of life in depressed patients. In children and adolescents and during the peripartum period, exercise interventions have been found have small-to-moderate effects, but studies varied in methodology and methodical quality could be improved (heterogeneous samples, blinding). Regular physical activity has been shown to have a protective effect on incident depression in adults, reducing odds by 17 to 21%. In children and adolescents, the effect tends to be smaller. Across 15 meta-analyses in samples with physical diseases, exercise-regimes have been shown to have positive effects on depressive symptoms in chronic conditions (such as pain, obesity or cardiovascular disease), cancer survivors, and in post-stroke, neurological and cardiovascular conditions, as well as in diabetes, chronic kidney disease, arthritis and HIV. Discussion: Exercise and physical activity have a wide range of benefits for depression and depressive symptoms in at-risk populations. Further research is needed to find optimal dose and duration of exercise-treatment and ways to sustainably increase physical activity in psychiatric populations and patients with chronic diseases.

Normalizing effect of heroin maintenance treatment on stress-induced brain connectivity

A single dose of heroin can reduce stress responses in heroin-dependent patients. Schmidt et al. report that increased amygdala-related functional connectivity during fearful face processing in heroin-dependent patients transiently normalises after a single dose of heroin. This measure may help to assess the efficacy of maintenance treatments in drug addictio

Joint declaration on mainstreaming RRI across Horizon Europe

Leading RRI researchers and practitioners, together with policymakers and stakeholder organisations, discussed the state-of-the-art and future perspectives for RRI at the ‘Pathways to Transformation’ conference in June 2019, an event which was extended beyond Brussels, for instance by ca. 330 original tweets and ca. 840 retweets from ca. 160 unique accounts. In the conference, many participants expressed their concern about an uncertain future for RRI in the EC. As a result, numerous large-scale EU-funded RRI projects signed a Joint Declaration, urging the European Commission to make RRI a key objective of the upcoming framework programme, Horizon Europe – a plea to both mainstream the approach across the programme and provide specific resources for strengthening the RRI knowledge base. As the Horizon Europe programme is being forged, it is timely to present the Declaration for a broader audience

Normalizing effect of heroin maintenance treatment on stress-induced brain connectivity

Recent evidence has shown that a single maintenance dose of heroin attenuates psychophysiological stress responses in heroin-dependent patients, probably reflecting the effectiveness of heroin-assisted therapies for the treatment of severe heroin addiction. However, the underlying neural circuitry of these effects has not yet been investigated. Using a cross-over, double-blind, vehicle-controlled design, 22 heroin-dependent and heroin-maintained outpatients from the Centre of Substance Use Disorders at the University Hospital of Psychiatry in Basel were studied after heroin and placebo administration, while 17 healthy controls from the general population were included for placebo administration only. Functional magnetic resonance imaging was used to detect brain responses to fearful faces and dynamic causal modelling was applied to compute fear-induced modulation of connectivity within the emotional face network. Stress responses were assessed by hormone releases and subjective ratings. Relative to placebo, heroin acutely reduced the fear-induced modulation of connectivity from the left fusiform gyrus to the left amygdala and from the right amygdala to the right orbitofrontal cortex in dependent patients. Both of these amygdala-related connectivity strengths were significantly increased in patients after placebo treatment (acute withdrawal) compared to healthy controls, whose connectivity estimates did not differ from those of patients after heroin injection. Moreover, we found positive correlations between the left fusiform gyrus to amygdala connectivity and different stress responses, as well as between the right amygdala to orbitofrontal cortex connectivity and levels of craving. Our findings indicate that the increased amygdala-related connectivity during fearful face processing after the placebo treatment in heroin-dependent patients transiently normalizes after acute heroin maintenance treatment. Furthermore, this study suggests that the assessment of amygdala-related connectivity during fear processing may provide a prognostic tool to assess stress levels in heroin-dependent patients and to quantify the efficacy of maintenance treatments in drug addiction

Chemokine ligand-receptor interactions critically regulate cutaneous wound healing

Background: Wound healing represents a dynamic process involving directional migration of different cell types. Chemokines, a family of chemoattractive proteins, have been suggested to be key players in cell-to-cell communication and essential for directed migration of structural cells. Today, the role of the chemokine network in cutaneous wound healing is not fully understood. Unraveling the chemokine-driven communication pathways in this complex process could possibly lead to new therapeutic strategies in wound healing disorders. Methods: We performed a systematic, comprehensive time-course analysis of the expression and function of a broad variety of cytokines, growth factors, adhesion molecules, matrixmetalloproteinases and chemokines in a murine cutaneous wound healing model. Results: Strikingly, chemokines were found to be among the most highly regulated genes and their expression was found to coincide with the expression of their matching receptors. Accordingly, we could show that resting and activated human primary keratinocytes (CCR3, CCR4, CCR6, CXCR1, CXCR3), dermal fibroblasts (CCR3, CCR4, CCR10) and dermal microvascular endothelial cells (CCR3, CCR4, CCR6, CCR8, CCR9, CCR10, CXCR1, CXCR2, CXCR3) express a distinct and functionally active repertoire of chemokine receptors. Furthermore, chemokine ligand-receptor interactions markedly improved the wound repair of structural skin cells in vitro. Conclusion: Taken together, we here present the most comprehensive analysis of mediators critically involved in acute cutaneous wound healing. Our findings suggest therapeutic approaches for the management of wound closure by targeting the chemokine network

AGO Recommendations for the surgical therapy of breast cancer: update 2022

The recommendations of the AGO Breast Committee on the surgical therapy of breast cancer were last updated in March 2022 (www.ago-online.de). Since surgical therapy is one of several partial steps in the treatment of breast cancer, extensive diagnostic and oncological expertise of a breast surgeon and good interdisciplinary cooperation with diagnostic radiologists is of great importance. The most important changes concern localization techniques, resection margins, axillary management in the neoadjuvant setting and the evaluation of the meshes in reconstructive surgery. Based on meta-analyses of randomized studies, the level of recommendation of an intraoperative breast ultrasound for the localization of non-palpable lesions was elevated to “++”. Thus, the technique is considered to be equivalent to wire localization, provided that it is a lesion which can be well represented by sonography, the surgeon has extensive experience in breast ultrasound and has access to a suitable ultrasound device during the operation. In invasive breast cancer, the aim is to reach negative resection margins (“no tumor on ink”), regardless of whether an extensive intraductal component is present or not. Oncoplastic operations can also replace a mastectomy in selected cases due to the large number of existing techniques, and are equivalent to segmental resection in terms of oncological safety at comparable rates of complications. Sentinel node excision is recommended for patients with cN0 status receiving neoadjuvant chemotherapy after completion of chemotherapy. Minimally invasive biopsy is recommended for initially suspect lymph nodes. After neoadjuvant chemotherapy, patients with initially 1 – 3 suspicious lymph nodes and a good response (ycN0) can receive the targeted axillary dissection and the axillary dissection as equivalent options

Multi order correction algorithms to remove image distortions from mass spectrometry imaging datasets

Time-of-flight secondary ion mass spectrometry imaging is a rapidly evolving technology. Its main application is the study of the distribution of small molecules on biological tissues. The sequential image acquisition process remains susceptible to measurement distortions that can render imaging data less analytically useful. Most of these artifacts show a repetitive nature from tile to tile. Here we statistically describe these distortions and derive two different algorithms to correct them. Both, a generalized linear model approach and the linear discriminant analysis approach are able to increase image quality for negative and positive ion mode datasets. Additionally, performing simulation studies with repetitive and non-repetitive tiling error we show that both algorithms are only removing repetitive distortions. It is further shown that the spectral component of the dataset is not altered by the use of these correction methods. Both algorithms presented in this work greatly increase the image quality and improve the analytical usefulness of distorted images dramatically
