[Vaccination in old age: an overview]. / Impfen im Alter: eine Übersicht.

Vaccinations against infectious diseases are a highly effective preventive measure, especially in old age due to the higher susceptibility to infections. As the effectiveness of vaccinations decreases in old age due to immune senescence but also due to comorbidities, specific, more immunogenic vaccines have been developed for this target group. In Germany, the Standing Commission on Vaccination (STIKO) publishes annually updated vaccination recommendations also specifically for the 60+ years age group. Since 2018, standard vaccinations for this group have included herpes zoster vaccination with adjuvanted inactivated vaccine. Since 2021, the use of the quadrivalent influenza high-dose vaccine is recommended for this age group. Currently, the annual COVID-19 vaccination and the single pneumococcal vaccination with the new 20-valent conjugate vaccine have been added as standard vaccinations. The free STIKO app provides an always up to date overview of standard and indicated vaccinations for all age groups.

[Influenza]. / Influenza.

Influenza is the infectious disease with the highest population-based mortality. It mainly affects those aged 60 years and older, mainly due to immune senescence, which also favors complicated courses and compromises vaccine effectiveness. Therefore, various approaches have been developed for more immunogenic vaccines, which are now available for use. The Ständige Impfkommission (STIKO) has taken this into account in its current recommendation on influenza vaccination and has recommended a quadrivalent, inactivated high-dose vaccine as the standard vaccine for all ≥ 60-year-olds. Despite these successes, vaccination for prevention remains underutilized. Germany has never reached the WHO vaccination target of 75% of the elderly population. The main reasons for this are a lack of confidence in the effectiveness of vaccination, a lack of/restricted risk perception of the disease, and barriers to implementation. Initial approaches to overcoming these barriers, such as low-threshold vaccination services by involving pharmacies, are being implemented. However, further steps are needed to realize the potential of influenza vaccination, especially for such vulnerable groups as older adults.

[The geriatric syndrome of anemia-Summary of the symposium of the working group anemia during the annual meeting of the German Geriatric Society 2018 in Cologne, Germany]. / Anämie als geriatrisches Syndrom ­ Zusammenfassung des Symposiums der AG Anämie anlässlich der Jahrestagung der Deutschen Gesellschaft für Geriatrie 2018 in Köln.

This year's symposium of the working group anemia of the German Geriatric Society (DGG) aimed to underline the multicausality of anemia in the aged and to highlight definition parallels with geriatric syndromes. For these reasons, nutritional and malignant causes for anemia were discussed and the influence of oxidative stress on the development of anemia was underlined. The need for ongoing research in the field of anemia in the aged was emphasized by the lack of perioperative transfusion strategies in geriatric patients.

[Anemia in the aged - a geriatric syndrome? : Second position paper on anemia in the aged by the working group anemia of the German Geriatric Society]. / Anämie im Alter ­ ein geriatrisches Syndrom? : Zweites Positionspapier zur Anämie im Alter der AG Anämie der Deutschen Gesellschaft für Geriatrie.

Geriatric syndromes are the pathognomonic columns of geriatric medicine. In contrast to many syndromes in younger people, in geriatric patients, the chief complaint does not typically represent the specific pathological condition underlying the change in health status. Geriatric syndromes are usually highly prevalent, multicausal and share a number of common risk factors. In recent years, scientific controversy over anemia in the aged has revealed a high prevalence in geriatric patients, which prompted the "working group on anemia" to publish its first position paper at a European level. The development of anemia is multicausal and the causes of the various forms of anemia range from iron deficiency, malnutrition, chronic inflammation, hormonal dysregulation, functional organ disorders, impaired synthesis to malignancies. The corresponding pathomechanisms are closely associated with the development of other geriatric syndromes such as gait disorders, sarcopenia, frailty, and falls. Against this backdrop, the "working group on anemia" of the German Geriatric Society has devised a second position paper:"Multicausality and the significant association between anemia and assessment-based quantifiable impairments suggest the consideration of anemia in the aged to be a geriatric syndrome."

[Clinical hematological symptoms of vitamin B12 deficiency in old age : Summarized overview of this year's symposium of the Working Group "Anemia in the Aged" on the occasion of the annual conference of the German Geriatric Society (DGG) in Frankfurt]. / Klinisch-hämatologisches Bild des Vitamin-B12-Mangels im Alter : Zusammenfassende Übersicht zum diesjährigen Symposium der AG Anämie im Alter anlässlich des Jahreskongresses der Deutschen Gesellschaft für Geriatrie in Frankfurt.

The interdisciplinary symposium of the working group "anemia in the aged" on the occasion of the annual conference of the German Society of Geriatrics focused this year on vitamin B12 deficiency in aged patients. Experts from hematopathology, clinical geriatrics and geriatric hematology presented the case of a 78-year-old woman and an interdisciplinary discussion was held on the epidemiology, clinical aspects as well as diagnostic and therapeutic steps. This article reviews the symposium on vitamin B12 deficiency in the aged in the context of the currently available literature.

Epidemiology of Pertussis and Pertussis-Related Complications in Adults: A German Claims Data Analysis.

INTRODUCTION: Pertussis is a highly contagious respiratory infection. It affects people of all ages, yet evidence of the impact of pertussis in adults with underlying conditions (UCs) is scarce. This study investigated the incidence and complication rate of pertussis in adult patients with and without UC. METHODS: A retrospective analysis was conducted using routinely collected German claims data between 2015 and 2019. Patients with and without different pneumological, cardiovascular, endocrinological, musculoskeletal, and psychological UCs were matched for incidence estimation. Logistic regression models were used to estimate the risk of pertussis depending on the presence of UCs. Negative binomial models were used to assess complication rates in patients with pertussis and with and without UC. RESULTS: In total, 4383 patients were diagnosed with pertussis during the study period. Patients with any UC had an increased risk for pertussis compared to matched patients without UC (odds ratio [OR] 1.72; 95% confidence interval [CI]1.60-1.84, p < 0.0001). Underlying asthma had the highest risk of pertussis (OR 2.70; 95% CI 2.50-2.91, p < 0.0001), followed by chronic obstructive pulmonary disease (OR 2.35; 95% CI 2.10-2.60, p < 0.0001) and depression (OR 2.08; 95% CI 1.95-2.22, p < 0.0001). Severe complications occurred in 10.8% of the pertussis cohort (13.4% with UC vs. 9.5% without UC). The UC-attributable effect on the risk of severe pertussis-related complications was significantly increased for any UC (incidence rate ratio [IRR] 1.29, 95% CI 1.19-1.39). The severe complication risk was also increased for patients aged 60+ (IRR 1.59, 95% CI 1.46-1.72). CONCLUSION: This study shows that adults with certain UCs have an increased risk for pertussis and are more likely to have complications. These results provide further evidence that pertussis is a relevant and impactful infectious disease in adults with and without certain UC, indicating that these patients need to be considered when developing vaccination recommendations to avoid pertussis and its associated complications.

Invasive meningococcal disease in older adults: current perspectives and call for action.

PURPOSE: Invasive meningococcal disease (IMD) is a devastating condition. While most attention is directed towards disease in children and adolescents, IMD poses an important cause of morbidity and mortality in adults ≥60 years. While immunization is a critical component of healthy ageing strategies, meningococcal immunization is not routinely offered to older adults. The aim of this review was to summarize clinical and epidemiological aspects of IMD and available immunization strategies, with a particular focus on disease in older individuals, to emphasize the importance of this rather neglected area. METHODS: An expert working group was established to evaluate clinical and epidemiological data to raise awareness of IMD in older individuals, and develop suggestions to improve the existing burden. RESULTS: Routine child and adolescent meningococcal immunization has substantially reduced IMD in these targeted populations. Consequently, prevalence and proportion of IMD among those ≥60 years, mostly unvaccinated, is increasing in developed countries (accounting for up to 25% of cases). IMD-related mortality is highest in this age-group, with substantial sequelae in survivors. IMD due to serogroups W and Y is more prevalent among older adults, often with atypical clinical features (pneumonia, gastrointestinal presentations) which may delay timely treatment. CONCLUSIONS: IMD in older adults remains overlooked and greater awareness is required at clinical and societal levels. We encourage clinicians and immunization policy makers to reconsider IMD, with a call for action to remedy existing inequity in older adult access to protective meningococcal immunization.

Epidemiology of Clostridioides difficile Infections in Germany, 2010-2019: A Review from Four Public Databases.

INTRODUCTION: Clostridioides difficile infection (CDI) is a recognized global threat especially for vulnerable populations. It is of particular concern to healthcare providers as it is found in both hospital and community settings, with severe courses, frequent recurrence, high mortality and substantial financial impact on the healthcare system. The CDI burden in Germany has been described and compared by analysing data from four different public databases. METHODS: Data on hospital burden of CDI have been extracted, compared, and discussed from four public databases for the years 2010-2019. Hospital days due to CDI were compared to established vaccine preventable diseases, such as influenza and herpes zoster, and also to CDI hospitalisations in the United States (US). RESULTS: All four databases reported comparable incidences and trends. Beginning in 2010, population-based hospitalised CDI incidence increased to a peak of > 137/100,000 in 2013. Then, incidence declined to 81/100,000 in 2019. Hospitalised patients with CDI were predominantly > 50 years of age. The population-based incidence of severe CDI was between 1.4 and 8.4/100,000 per year. Recurrence rates were between 5.9 to 6.5%. More than 1,000 CDI deaths occurred each year, with a peak of 2,666 deaths in 2015. Cumulative CDI patient days (PD) were between 204,596 and 355,466 each year, which exceeded cumulated PD for influenza and herpes zoster in most years, though year-to-year differences were observed. Finally, hospitalized CDI incidence was higher in Germany than in the US, where the disease is well recognized as a public health threat. CONCLUSIONS: All four public sources documented a decline in CDI cases since 2013, but the disease burden remains substantial and warrants continued attention as a severe public health challenge.

[Vaccination in older adults: compulsory or voluntary exercise?] / Impfen im Alter ­ Pflicht oder Kür?

BACKGROUND: Immunosenescence leads to an increasing susceptibility to infections. Therefore, vaccination is an essential element of prevention. The recommendations of the permanent vaccination commission (STIKO), a committee at the Robert-Koch-Institute, affiliated to the German Government, are updated every year and include a particular section dealing with older adults. CURRENT DEVELOPMENTS: Immunosenescence reduces vaccine effectiveness. Thus, older adults and patients with multimorbidity are in need of more immunogenic vaccines. Cell culture derived quadrivalent influenza vaccine, trivalent adjuvanted vaccine and a high dose influenza vaccine show higher immune response in these groups. STIKO actually recommends an adjuvanted herpes zoster subunit vaccine to all adults in the age of 60 and above because of its vaccine effectiveness of 90 % in all age groups. The increasing travel activities of older adults require travel vaccination advice that takes into account travel destination as well as multimorbidity. Adjusted vaccination schedules and controlling of antibody titers have to be considered. OUTLOOK: New vaccines are under development, that are more immunogenic and therefore more effective (e. g. pneumococcal vaccine) or that prevent infections for which a vaccine was previously not available (e. g. norovirus vaccine).

[Care requirements for elderly cancer patients]. / Erfordernisse älterer Tumorpatienten vor dem Hintergrund der Versorgungsrealität.

The oncology care system is insufficiently directed to the treatment situation of elderly tumour patients. There is a lack of specific studies focusing on the application and effects of antineoplastic substances in elderly patients to forward the utilisation of all available therapeutical options. The reality of care of elderly patients, especially elderly women, is marked by problems of access to the treatment opportunities. Questions of social support have to be raised. A specialised geriatric assessment in oncology can improve diagnostic preconditions in the treatment of the elderly. Restrictions of activities of daily living, comorbidities, cognitive handicaps, and malnutrition are to be surveyed among all patients > 70 years of age. Studies for the systematic involvement of assessments in the treatment routine are necessary. The cooperation of geriatricians and oncologists has to become a more routine process to work out diagnosis and treatment standards for elderly cancer patients. The oncology care system has to meet the challenge of providing adequate care which links specialised tumour treatment with palliative care, especially for elderly patients with advanced tumour diseases.

[Emergency Medicine in Remote Settings]. / Notfallmedizin abseits schnell erreichbarer medizinischer Infrastruktur.

For many acute diseases and injuries, treatment does not differ between industrialised environment and wilderness setting. However, for some emergencies, treatment needs to be adapted if advanced medical care facilities cannot be reached within 4 hours.In these situations, dislocated joints and fractures should be reduced quickly. Contaminated wounds should be cleaned carefully, with drinking water being sufficient when no sterile solution is available. A patient with a contaminated wound should receive a systemic antibiotic coverage within one hour. Keeping an injured patient warm is crucial to prevent disseminated coagulation.In most cases in the wilderness, cardiopulmonary resuscitation (CPR) should be stopped after 20 minutes; if no return of spontaneous circulation (ROSC) has occurred. However, in case of severe hypothermia, drowning or cardiac arrest due to lightning, prolonged CPR may be feasible.Handwashing with soap and water and use of alcohol gels are effective measures for the prevention of travellers' diarrhoea during expeditions.

Anemia in the aged is not ageing related: position paper on anemia in the aged by the "working group anemia" of the German Geriatric Society (DGG).

Anemia in the aged is a frequent but still under-estimated problem in geriatric patients. However, in recent years increasing research on anemia in the aged has improved awareness and interest in this clinically relevant problem. Guidelines for diagnostic and therapeutic steps are now required to improve the treatment of anemic aged patients. For encouraging the development of diagnostic and therapeutic recommendations, the "working group anemia" of the German Geriatric Society (DGG) has issued a position paper on anemia in the aged, based on the current literature. The statements are (1) that anemia has to be considered a highly prevalent but not a physiologic finding in aged persons; (2) that reference values for hemoglobin concentration are independent of age, indicating that WHO reference values for anemia definition are valid for aged persons; (3) that anemia in the aged is associated with functional and cognitive impairment based on comprehensive geriatric assessment (CGA), requiring diagnosis and treatment.
