[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.

[Non-invasive Mechanical Ventilation in Acute Respiratory Failure. Clinical Practice Guidelines - on behalf of the German Society of Pneumology and Ventilatory Medicine]. / S2k-Leitlinie Nichtinvasive Beatmung als Therapie der akuten respiratorischen Insuffizienz.

The guideline update outlines the advantages as well as the limitations of NIV in the treatment of acute respiratory failure in daily clinical practice and in different indications.Non-invasive ventilation (NIV) has a high value in therapy of hypercapnic acute respiratory failure, as it significantly reduces the length of ICU stay and hospitalization as well as mortality.Patients with cardiopulmonary edema and acute respiratory failure should be treated with continuous positive airway pressure (CPAP) and oxygen in addition to necessary cardiological interventions. This should be done already prehospital and in the emergency department.In case of other forms of acute hypoxaemic respiratory failure with only mild or moderately disturbed gas exchange (PaO2/FiO2 > 150 mmHg) there is no significant advantage or disadvantage compared to high flow nasal oxygen (HFNO). In severe forms of ARDS NIV is associated with high rates of treatment failure and mortality, especially in cases with NIV-failure and delayed intubation.NIV should be used for preoxygenation before intubation. In patients at risk, NIV is recommended to reduce extubation failure. In the weaning process from invasive ventilation NIV essentially reduces the risk of reintubation in hypercapnic patients. NIV is regarded useful within palliative care for reduction of dyspnea and improving quality of life, but here in concurrence to HFNO, which is regarded as more comfortable. Meanwhile NIV is also recommended in prehospital setting, especially in hypercapnic respiratory failure and pulmonary edema.With appropriate monitoring in an intensive care unit NIV can also be successfully applied in pediatric patients with acute respiratory insufficiency.

The timely integration of palliative medicine is an important component in the treatment of various advanced diseases. While a German S­3-guideline on palliative medicine exists for patients with incurable cancer, a recommendation for non-oncological patients and especially for palliative patients presenting in the emergency department or intensive care unit is missing to date. Based on the present consensus paper, the palliative care aspects of the respective medical disciplines are addressed. The timely integration of palliative care aims to improve quality of life and symptom control in clinical acute and emergency medicine as well as intensive care.

The timely integration of palliative medicine is an important component in the treatment of various advanced diseases. While a German S-3-guideline on palliative medicine exists for patients with incurable cancer, a recommendation for non-oncological patients and especially for palliative patients being treated in the emergency department or intensive care unit is missing to date. Based on the present consensus paper, the palliative care aspects of the respective medical disciplines are addressed. The timely integration of palliative care aims to improve quality of life and symptom control in clinical acute and emergency medicine as well as intensive care.

Intensive care of geriatric patients-a thin line between under- and overtreatment.

Demographic developments are leading to an ever-increasing proportion of elderly and aged patients in hospitals at all levels of care, and even more patients from these age groups are to be expected in the future. Based on the projected population development, e.g., in Norway, an increase in intensive care beds of between 26 and 37% is expected by 2025. This poses special challenges for the treatment and management of geriatric intensive care patients. The acute illness is not the only decisive factor, but rather the existing multimorbidity and functional limitations of this vulnerable patient group must likewise be taken into account. Age per se is not the sole determinant of prognosis in critical patients, even though mortality increases with age.

[Liver dysfunction in geriatric patients]. / Leberfunktionsstörungen bei geriatrischen Patienten.

With increasing age in addition to alterations of the cardiovascular, neurocognitive and musculoskeletal systems, alterations also occur in hepatic organ function. As a result of morphological and functional age-related processes, progressive hepatic organ dysfunction can develop with increased vulnerability with respect to endogenous and exogenous noxious substances and impaired hepatic regenerative capacity. Frequent causes of liver dysfunction in the geriatric population include non-alcoholic fatty liver disease (NAFLD), alcoholic liver disease, viral hepatitis, autoimmune hepatitis and drug-induced liver injury. The prompt initiation of adequate diagnostic measures for identification of the underlying etiology is important for timely initiation of appropriate treatment and to reduce the risk of progressive impairment of hepatic function and associated complications.

[Diabetes mellitus in old age]. / Diabetes mellitus im Alter.

In the treatment of diabetes in old age cognitive, functional and constitutional resources of the individual must be taken into account. Purely glycated hemoglobin (HbA1c)-oriented treatment goals are less relevant. The primary focus should be freedom from symptoms while avoiding hypoglycemia and maintaining the quality of life. The geriatric assessment helps to clarify the current functional, psychological and cognitive status as well as the need for support in multimorbid older people and to define appropriate treatment strategies. With drug treatment of diabetes in old age, particular attention must be paid to renal insufficiency and dehydration as well as slow dose adjustments. According to the Robert Koch Institute (RKI), diabetes patients belong to the risk group for a severe course of the coronavirus disease 2019 (COVID-19); further risk factors are high blood pressure, underlying oncological diseases, cerebrovascular and coronary heart diseases.

[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.

Neurogeriatrics-a vision for improved care and research for geriatric patients with predominating neurological disabilities.

Geriatric medicine is a rapidly evolving field that addresses diagnostic, therapeutic and care aspects of older adults. Some disabilities and disorders affecting cognition (e.g. dementia), motor function (e.g. stroke, Parkinson's disease, neuropathies), mood (e.g. depression), behavior (e.g. delirium) and chronic pain disorders are particularly frequent in old subjects. As knowledge about these age-associated conditions and disabilities is steadily increasing, the integral implementation of neurogeriatric knowledge in geriatric medicine and specific neurogeriatric research is essential to develop the field. This article discusses how neurological know-how could be integrated in academic geriatric medicine to improve care of neurogeriatric patients, to foster neurogeriatric research and training concepts and to provide innovative care concepts for geriatric patients with predominant neurological conditions and disabilities.

The proportion of elderly, frail, and multimorbid people has increased dramatically in recent decades resulting from demographic changes and will further increase, which will impact acute medical care. Prospective, randomized studies on geriatric intensive care are still lacking. There are also no international or national recommendations regarding the management of critically ill elderly patients. Based on an expert opinion, this consensus paper provides 16 statements that should be considered when dealing with geriatric critical care patients.
