Myositis is a connective tissue disease which is most frequently diagnosed in women aged 40-60 years. Due to a clear association with underlying malignant diseases, general tumor screening is recommended whenever it is diagnosed. Colorectal carcinoma (CRC) is a common malignant disease, and the typical at-risk group comprised, to date, patients older than 55 years. However, with the rising incidence of so-called early-onset colorectal carcinoma (EO-CRC), an increasingly important patient population is emerging in the 20- to 50-year age range. One reason for the rising incidence is suggested to be an increase in classic risk factors at younger ages. Here, the case of a 34-year-old female patient who presented with the leading paraneoplastic syndrome of myositis and was diagnosed with a sporadic form of CRC is reported. Monitoring of known risk factors as early on as in young adulthood and greater attention in the presence of symptoms such as gastrointestinal hemorrhage or paraneoplastic syndromes seem necessary to compensate for the time delay in diagnosis that currently still exists and the associated worse oncologic outcome.

Respiratory syncytial virus (RSV) is a frequent cause of respiratory infections in all age groups. Infections in infants and older adults frequently result in severe disease and complications. There is no specific antiviral treatment against RSV. The characterization of the structure of the fusion (F) protein in its immunogenic prefusion conformation has enabled the development of novel vaccines directed against the prefusion protein as the antigen. These include an adjuvanted monovalent vaccine (Arexvy) and a nonadjuvanted bivalent vaccine (Abrysvo). Both are approved and indicated for use in older adults, in whom they have been shown to be over 80% effective in the protection against symptomatic RSV infections and associated lower respiratory tract diseases. Abrysvo is approved for use in pregnancy to protect the newborn through the transplacental transfer of high-titer maternal antibodies. The vaccine has been shown to have an efficacy of over 80% in the first 3 months of life to protect the infant from severe RSV-associated lower respiratory disease but slightly deceases after an age of 6 months. The clinical studies demonstrated the safety of the vaccines in both adults and pregnant women. The rate of undesired side effects was low in all studies and severe side effects were very rare. The new vaccines are efficacious new tools to prevent RSV-associated disease and complications in high-risk groups. For infants, an alternative strategy can be passive immunization with monoclonal antibodies, including the recently developed nirsevimab, which has also shown high efficacy.

Background: Emerging or re-emerging viral diseases have a pandemic potential and threaten global health. Vaccination is of crucial importance in the prevention of emerging and re-emerging viral diseases.

Objective: Description of the current status of vaccine development against Filoviridae, highly pathogenic coronaviruses, smallpox viruses, influenza viruses and arboviruses.

Material and methods: Focused literature search.

Results: The World Health Organization (WHO) regularly publishes a list of infectious diseases that are expected to pose a major threat to humanity as they are could potentially trigger new pandemics; however, in addition to these human-to-human transmissible diseases, some arboviruses also have pandemic potential. In recent years numerous new vaccines, some of which are highly effective, have been licensed against new and re-emerging viral diseases and other promising vaccine candidates are currently in development.

Conclusion: There are still gaps in the development of vaccines in the area of Filoviridae and highly pathogenic coronaviruses. Vaccinations against smallpox viruses have been available for a long time. Developing influenza vaccines against novel strains in a timely manner is a challenge and universal influenza vaccines could be a possible solution. Modern vaccines are available against the arboviruses dengue and Chikungunya fever.

Pneumococcal vaccination plays a crucial role in the prevention of bacterial respiratory infections caused by Streptococcus pneumoniae. Pneumococci are responsible for diseases such as pneumonia, sinusitis and acute otitis media and can cause serious invasive infections such as meningitis and bacteraemia. Pneumococcal pneumonia leads to increased morbidity and mortality, particularly in patients with chronic lung diseases such as chronic obstructive pulmonary disease (COPD). The introduction of 13-valent conjugate vaccines (pneumococcal conjugate vaccine 13 [PCV13]) has significantly reduced the burden of disease. However, infections caused by serotypes not covered by PCV13 continue to occur. Current vaccines such as the 20-valent conjugate vaccine (PCV20) provide extended serotype coverage and have shown a robust immune response in clinical trials. The recently updated recommendations of the German Standing Committee on Vaccination (Ständige Impfkommission, STIKO) include the use of PCV20 for all indication categories in adults, which represents a simplified and more effective vaccination strategy. Future developments include vaccines with even broader serotype coverage and improved immunological properties; these are expected to further reduce the burden of pneumococcal disease. Improving vaccination uptake and increasing vaccination rates, particularly among at-risk groups, remain key objectives to protect public health in the long term.

Metformin has been recommended as first-line pharmacological therapy in type‑2 diabetes (T2D) since 1998. It was the first medication that demonstrated cardiovascular benefits in obese subjects with T2D. Efficacy and safety of metformin have since been demonstrated in further studies and in real-world data on its use in practice. The recommendation of metformin as baseline therapy has reached wide acceptance internationally. During the period 2015-2021, large cardiovascular safety trials showed superiority for cardiovascular morbidity and partly also mortality outcomes for most substances of the novel antidiabetic substance classes of GLP‑1 receptor agonists and SGLT‑2 inhibitors in people with T2D and very high cardiovascular risk or preexisting cardiovascular disease. The evidence for these two substance classes is now broader than for metformin. Therefore, the question arises as to whether it is still justified to recommend metformin generally as first-line therapy in T2D. This article provides an overview of the study data as well as an overview of the evidence-based guidelines. The status and position of metformin in the treatment of T2D are discussed.

Cardiovascular risk factors (high blood pressure, smoking, overweight, type 2 diabetes, dyslipidemia, physical inactivity) substantially rise with increasing age, particularly after middle age, whereby women are affected to a much greater extent. In the population of Saxony-Anhalt the prevalence of cardiovascular risk factors is clearly increased and the population structure in Saxony-Anhalt is particularly characterized by a high average age as well as high morbidity and mortality rates due to cardiovascular diseases. Saxony-Anhalt therefore provides a model character for the demographic development in Europe. This review article discusses strategies for the implementation of target group-specific cardiovascular preventive strategies in the Federal State of Saxony-Anhalt with special consideration of age and sex. When preventive medicine facilities are established and innovative treatment possibilities for patients with cardiovascular risks are created, prevention should also become available in rural areas.

The coronavirus disease 2019 (COVID-19) pandemic emphasized the importance of vaccinations for the prevention of life-threatening diseases and for avoiding the overburdening of the healthcare system. Despite the clear advantage of vaccinations, increasing vaccine hesitancy has been observed worldwide, especially among young people who are potential future parents. Vaccine hesitancy describes the delayed or lack of willingness to utilize recommended vaccinations and represents a substantial challenge for public health. This article analyzes the causes of vaccine hesitancy in the postpandemic period and discusses factors that could make communication successful. The role of artificial intelligence and structured evidence-based discussion techniques, such as the empathetic refutation interview, are emphasized. The aim is to provide practice-oriented recommendations to be able to provide physicians with tools that can help in the education counselling with insecure patients and can promote the acceptance of vaccinations.
