There is increasing consensus on the relevance of exercise interventions for the treatment and prevention of unipolar depression. The present review article aims to provide a practitioner-friendly overview of recent insights into the underlying neurobiological mechanisms of exercise interventions in depression in order to enhance their dissemination and acceptance. Exercise has proven antidepressive efficacy in major depressive disorders. Furthermore, it has demonstrated a protective effect on the development of depressive symptoms. Neurobiological research has shown that exercise increases the volume of gray matter in the brain, improves the microstructure of white matter and leads to a higher functional connectivity in brain regions implicated in major depressive disorders. On a molecular level, preliminary findings indicate that exercise has anti-inflammatory, neuroplastic and antioxidative effects, which could represent the basis for the effects observed on a brain structural and functional level. Exercise interventions should be recommended as an adjunct therapy for all patients with major depressive disorder.As population age, healthcare systems and providers are likely to experience a substantial increase in the proportion of elderly patients requiring emergency surgery. Emergency surgery, compared with planned surgery, is strongly associated with increased risks of adverse postoperative outcomes due to the short time available for diagnosis, optimization, and intervention in patients presenting with physiological derangement. These patient populations, who are often frail and burdened with a variety of co-morbidities, have lower reserves to deal with the stress of the acute condition and the required emergency surgical intervention. In this review article, we discuss topical areas where mitigation of the physiological stress posed by the acute condition and asociated surgical intervention may be feasible. We consider the impact of the adrenergic response and use of beta blockers for these high-risk patients and discuss common risk factors such as frailty and delirium. A proactive multidisciplinary approach to peri-operative care aimed at mitigation of the stress response and proactive management of common conditions in the older emergency surgical patient could yield more favorable outcomes.Every year, more than 20,000 patients with polytrauma are treated in Germany. The term polytrauma refers to simultaneous injury to several body regions that are individually or collectively life-threatening for the patient. However, this assessment is made based on appropriate scoring systems. Adequate treatment of these patients requires not only medical care at the highest level, but also coordination of organizational/logistical processes. The link between preclinical and clinical care is treatment in the shock room, which should be led by a defined, experienced "trauma leader". Treatment algorithms are based on the current S3 guideline Polytrauma/Serious Injury Treatment of the AWMF and the White Paper on Serious Injury Care. Here, recommendations are defined regarding personnel, spatial, logistical and material requirements. Every shock room team should be trained regularly and have theoretical and practical knowledge on the application of shock room algorithms. This can improve the quality of treatment and thus the probability of survival of critically ill patients. In the shock room itself, the focus is on standardized and priority-oriented assessment and stabilization of the patient. Due to the varying quality of care for severely injured patients in Germany, the TraumaNetwork DGU® initiative was implemented by the German Society of Trauma Surgery to improve the treatment of polytrauma patients by defining standards and improving processes and organization in the care of severely injured patients. In Germany, there are currently 615 participating hospitals that are organized in 52 local trauma networks, some of which are cross state borders.Genetic analyses have revealed the pivotal contribution of microglial dysfunctions to the pathogenesis of Alzheimer's disease (AD). Along AD progression, the accumulation of danger-associated molecular patterns (DAMPs) including beta-amyloid and hyperphosphorylated tau continuously stimulates microglia, which results in their chronic activation. Chronically activated microglia secrete excessive pro-inflammatory cytokines, which further regulate microglial responses towards DAMPs. This has spurred longstanding interest in targeting cytokine-induced microglial responses for AD therapeutic development. However, the cytokine-induced microglial state transition is not comprehensively understood. Cytokines are assumed to induce microglial state transition from a resting state to an activated state. However, recent evidence indicate that this microglial state transition involves multiple sequential functional states. Moreover, the mechanisms by which different functional states within the cytokine-induced microglial state transition regulate AD pathology remain unclear. In this review, we summarize how different cytokine signaling pathways, including those of IL-33 (interleukin-33), NLRP3 inflammasome-IL-1β, IL-10, and IL-12/IL-23, regulate microglial functions in AD. Furthermore, we discuss how the modulation of these cytokine signaling pathways can result in beneficial outcomes in AD. Finally, we describe a stepwise functional state transition of microglia induced by cytokine signaling that can provide insights into the molecular basis of the beneficial effects of cytokine modulation in AD and potentially aid therapeutic development.In response to the COVID-19 pandemic the routine surveillance system for infectious diseases had to be adapted. The disease was unknown before the first cases were reported under a catch-all notification requirement for new and threatening pathogens and diseases, but specific notification requirements for SARS-CoV‑2 detection by laboratories as well as for suspect cases of COVID-19 diagnosed by physicians were soon integrated in the infectious diseases protection act. check details This article describes how the notification system for infectious diseases was adapted in 2020 to meet the requirements of the COVID-19 pandemic.In addition to the notification requirements, the list of data that is collected through the notification system was also amended. To facilitate the work of laboratories and local health authorities we have established the possibility for electronic reporting.Additionally, the software used for case and contact management within the local health authorities had to be adapted accordingly.COVID-19 notification data is important for the assessment of the current epidemiological situation and daily updated data was published by the Robert Koch Institute.
