SARS-COV-2 : During the COVID-19 pandemic, mRNA-based vaccines were approved for the first time. The mRNA encodes for the viral spike protein, leading to the development of specific antibodies and T-cells, providing effective protection against severe illness and death from COVID-19. New variants regularly emerge due to rapid viral evolution. Available COVID-19 vaccines can be adapted to circulating variants. For the upcoming winter season, adapted vaccines against the Omicron sublineage JN.1 have been recommended. SEASONAL INFLUENZA : Seasonal influenza viruses change significantly with regard to their antigenic properties each season, necessitating updated vaccines. The WHO predicts and recommends which genetic variants should be included in the vaccine. Quadrivalent vaccines were recommended previously, but for 2024/2025, trivalent vaccines are advised as the Influenza B/Yamagata lineage has not circulated since 2020. For all people over 60 years of age, a high-dose vaccine is recommended, showing slightly improved efficacy.

Chronic infection with hepatitis C virus (HCV) is a common cause of complications such as liver cirrhosis and hepatocellular carcinoma (HCC). It is one of the most significant infectious diseases worldwide, posing a substantial health burden. Since the introduction of direct-acting antiviral agents (DAAs), the treatment landscape has undergone a revolution. HCV infection is curable, and the treatment is safe and well tolerated. Due to the availability of this effective therapeutic option, the World Health Organization (WHO) set an ambitious goal in 2015 to eliminate Hepatitis C by 2030, a goal that the German government also embraced in 2016. The key tasks involve identifying previously undiagnosed cases and ensuring they receive antiviral treatment. Addressing at-risk populations through specific measures, including micro-elimination projects and population-wide campaigns, is essential to achieving the WHO's target both in Germany and globally.

The KDIGO Update 2024 was supplemented by new "Clinical Practice Points", which were derived from the current evidence but are not necessarily comprehensively proven by prospective controlled studies. The most significant change in the Update 2024 for Lupus nephritis concerns the recommendations for induction therapy for lupus nephritis classes III and IV. The basis is still high-dose glucocorticoid treatment and the use of hydroxychloroquine. The 2 new developments in the 2024 Update concerning ANCA-associated nephritis are based on the studies on the use of the C5a receptor inhibitor Avacopan and the increasing data on induction protocols with reduced glucocorticoid dosage. Due to the inconsistency and variability of the conditions under which blood pressure measurements are carried out in practice, an international consensus statement was issued which defines 4 steps to achieve sufficient validity of the measurement results. CKD-MBD Controversies Conference 2023: The update for CKD-MBD, which was discussed in the Controversies Conference 2023, is in progress and has not been released yet. However, there were no serious contradictions between the 2023 data and the 2017 guidelines - the risk assessment regarding calcium-containing phosphate binders may have been put into perspective.

Acute inflammation of the liver (hepatitis) can be triggered by at least five different hepatotropic viruses - hepatitis viruses A, B, C, D and E. Hepatitis viruses A and E are transmitted via contaminated food and smear infections, whereas hepatitis viruses B, C and D are transmitted through direct contact with blood and other body fluids when these penetrate the skin or mucous membranes. This article is intended to provide a brief overview of the different forms of acute viral hepatitis, diagnosis, course and treatment.

Patients with liver cirrhosis often exhibit complex alterations in their hemostatic system that can be associated with both bleeding and thrombotic complications. While prophylactic correction of abnormal coagulation parameters should be avoided, an individualized approach is recommended prior to invasive procedures, whereby specific preventive measures to stabilize hemostasis should be based on the periprocedural bleeding risk. While the haemostatic system of patients with compensated cirrhosis is often in a rebalanced haemostatic state due to a parallel decline in both pro- and anti-haemostatic factors, a decompensation of liver cirrhosis can lead to destabilization of this fragile equilibrium. Since conventional coagulation tests do not adequately capture the complex changes in the hemostatic system in cirrhosis, functional analysis methods such as viscoelastic tests or thrombin generation assays can be used for evaluating the coagulation status. This review describes the underlying pathophysiological changes in the hemostatic system in liver cirrhosis, provides an overview of diagnostic methods and discusses therapeutic measures in case of bleeding and thrombotic complications.

Frailty is a clinical condition associated with aging and resulting in increased risk of adverse outcomes upon exogenous or endogenous stressors. In oncology, cancer treatment itself can be a stressor event. In older cancer patients, frailty therefore not only enhances the probability of age-related health events such as institutionalization or falls, but also of treatment complications such as toxicity and interruption or discontinuation of therapy. As demonstrated by recent randomized-controlled trials conducted in older cancer patients receiving systemic treatment, the evaluation of frailty by geriatric assessment (GA) followed by an adjustment of the oncological therapy as well as targeted frailty interventions help to improve cancer treatment tolerability and feasibility. Based on these data, the American Society of Clinical Oncology (ASCO) updated the clinical practice guidelines for the assessment and management of vulnerabilities in older adults receiving systemic cancer therapy. The guideline recommends the use of a new GA-tool named 'practical geriatric assessment' (PGA) to foster the implementation of GA-based frailty assessment and management in routine cancer care. This article describes the background and key aspects of these recent advances.

Tobacco control, psychosocial and medical assistance regarding tobacco cessation is still a hidden potential within the German health care system. So far doctors rarely talk to their patients about their smoking status and physical and psychological benefits of quitting.This paper focusses on recommended current diagnostic and treatment standards, as well as evidence-based methods to address the topic on how to stop smoking and its association with certain diseases such as COPD, lung cancer and COVID-19 infection. The role of e-cigarettes as a cessation tool and its health related risks are critically examined. Consequences and advice how to implement smoking cessation procedures into daily practice are presented.
