RESUMO
The accumulation of respiratory infections in the winter months repeatedly highlights the relevance of prevention through vaccination, even beyond a pandemic. Current developments in this field are therefore highly relevant, particularly for older people who are more susceptible to infections due to immune senescence and comorbidities. The Standing Committee on Vaccination (STIKO) has responded accordingly by recommending the 20-valent pneumococcal conjugate vaccine PCV20 for standard and indication vaccination of adults. Furthermore, new vaccines against respiratory syncytial virus (RSV) infections are available for which the STIKO has not yet issued a recommendation. The development of other more effective and more immunogenic vac2cines is being driven in particular by new technologies, such as mRNA or vector vaccines. Various higher valent pneumococcal vaccine candidates and, for example, universal influenza vaccines are also already in development.

BACKGROUND: There is an urgent need for improved influenza vaccines especially for older adults due to the presence of immunosenescence. It is therefore highly relevant to compare enhanced influenza vaccines with traditional influenza vaccines with respect to their effectiveness. OBJECTIVE: To compare vaccine efficacy and effectiveness of adjuvanted influenza vaccines (aTIV/aQIV) vs. non-adjuvanted standard-dose (TIV/QIV) and high-dose (TIV-HD/QIV-HD) influenza vaccines regarding influenza-related outcomes in older adults, complementing findings from the European Centre for Disease Prevention and Control (ECDC)'s systematic review of enhanced seasonal influenza vaccines from February 2020. METHODS: A systematic literature search was conducted in Embase and MEDLINE to identify randomised controlled trials, observational studies and systematic reviews, published since ECDC's systematic review (between 7 February 2020 and 6 September 2021). Included studies were appraised with either the Cochrane Risk of Bias tool, ROBINS-I or AMSTAR 2. RESULTS: Eleven analyses from nine real-world evidence (RWE) studies comprising â¼53 million participants and assessing the relative vaccine effectiveness (rVE) of aTIV vs. TIV, QIV and/or TIV-HD in adults aged ≥65 years over the 2006/07-2008/09 and 2011/12-2019/20 influenza seasons were identified. Nine analyses found that aTIV was significantly more effective than TIV and QIV in reducing influenza-related outcomes by clinical setting and suspected influenza outbreaks (rVE ranging from 7.5% to 25.6% for aTIV vs. TIV and 7.1% to 36.3% for aTIV vs. QIV). Seven analyses found similar effectiveness of aTIV vs. TIV-HD in reducing influenza-related medical encounters, inpatient stays and hospitalisations/emergency room visits. In three analyses, aTIV was significantly more effective than TIV-HD in reducing influenza-related medical encounters and office visits (rVE ranging from 6.6% to 16.6%). Risk of bias of identified studies was moderate to high. CONCLUSIONS: Our study suggests that both adjuvanted and high-dose vaccines are effective alternatives for vaccination programmes in older adults and preferable over conventional standard-dose vaccines.

In Germany up to 20% of the population are affected by influenza every year. Particularly for the elderly, influenza is related to high morbidity and mortality and 90% of deaths are related to the group of 60 years and older. In this context, seasonal influenza caused by influenza A (H3N2) viruses is exceedingly relevant for the elderly. The aging of the immune system, immunosenescence, is well documented as the cause of increased susceptibility to infection and change of typical symptoms. This can cause a delay in diagnosing and treatment of influenza infections. Furthermore, immunosenescence can lead to decreased efficacy of vaccination. Adjuvanted vaccines and vaccines with higher antigen content cause an enhanced immune response and are therefore especially suitable for prevention. The Standing Vaccination Committee (STIKO) recommends vaccination against seasonal influenza for all persons 60 years of age and over as well as for nursing home residents, pregnant women and chronically ill patients. For the coming influenza season 2018/19, the STIKO generally recommends the administration of quadrivalent (tetravalent) vaccines for the first time.

BACKGROUND: The prevalence of nasopharyngeal colonization with Staphylococcus aureus can reach 20-30% among the population, which can lead to invasive infection. AIM: To investigate the prevalence of colonization among different age groups, and analyse S. aureus strain-specific virulence patterns. METHOD: For analysis of the prevalence of colonization, groups consisting of newborns, healthy volunteers aged 5-60 years, and nursing home residents aged >80 years were examined with nasopharyngeal swabs. After S. aureus was cultured, genetic analysis and phenotypic virulence testing were performed by cell-based assays. FINDINGS: Among 924 volunteers, the overall colonization rate was approximately 30%, with a peak in subjects aged 5-10 years (49%). Neonates and subjects aged >80 years showed different distributions of clonal clusters. Overall, the strains of all age groups exhibited virulence characteristics that can contribute to the development of infection. In particular, the neonatal strains exhibited a high incidence of toxin genes that resulted in increased cytotoxic effects compared with the other strains tested. CONCLUSIONS: Colonizing strains showed a virulence profile in all age groups, which may lead to the establishment of invasive infection. Consequently, decolonization measures could be considered for selected patients depending on the risk of infection.

Infectious diseases are responsible for up to 5% of fatalities even in developed countries. In addition, there is an increasing susceptibility for infections in elderly people due to physiological aging of the immune system. The principles of vaccination are based on a targeted activation of the human immune system. Principally, a distinction is made between passive immunization, i.e. the application of specific antibodies against a pathogen and active immunization. In active immunization, i.e. vaccination, weakened (attenuated) or dead pathogens or components of pathogens (antigens) are administered. After a latency period that depends on the vaccine, complete immune protection is achieved and immunity is maintained for a certain period of time. In contrast to dead vaccines, by the use of live vaccines there is always a risk for infection with the administered vaccine. In passive immunization antibodies are administered. As a rule passive immunization is carried out in persons who have had contact with an infected person and in whom no or uncertain immunity against the corresponding disease is present. Based on the recommendations of the Standing Committee on Vaccination (STIKO), influenza, pneumococcal, herpes zoster, early summer meningoencephalitis (FSME) and travel vaccines are described.

BACKGROUND: The aim of this study is to compare very elderly female patients with a younger control group after prolapse surgery with regard to co-morbidity and complications. METHOD: In a case-control design, the consecutive data of patients after prolapse surgery at the age of over 80 years and those of a control group were analysed by means of the Clavien-Dindo (CD) classification of surgical complications, the Charlson Comorbidity Index and the Cumulative Illness Rating Scale Geriatrics (CIRS-G). Statistics: Student's t, Fisher's exact and Mann-Whitney U tests. RESULTS: The analysis comprised n = 57 vs. n = 60 operations. In the very elderly patients there was often a grade IV prolapse (p < 0.001), apical fixations were more frequent (p < 0.001), but the operating times were not different. In the very elderly patients 21â% CD II+III complications were observed, in the control group 6.6â% (p = 0.031). No CD IV and V complications occurred in either group, the duration of inpatient stay amounted to 5 (± 1) vs. 4.1 (± 0.8; p < 0.001) days, the very elderly patients needed an inpatient follow-up more frequently (p < 0.001). The co-morbidities of the very elderly patients differed from those of the control group in number (median 2.0 vs. 1.5; p < 0.001), in CIRS-G (4.1 ± 2.2 vs. 2.4 ± 1.7; p < 0.01) and in Charlson Index (1.6 ± 1.6 vs. 0.5 ± 0.7; p < 0.001). CONCLUSIONS: A prolapse in very elderly women can be safely managed by surgery. In no case did the complications require intensive care treatment nor were they life-threatening, but they did lead to a longer duration of hospital stay and more frequently to further treatment geriatric or inpatient internal medicine facilities.
RESUMO
Aging of the immune system, so-called immunosenescence, is well documented as the cause of increased infection rates and severe, often complicated courses of infections in older adults. This is particularly true for pneumococcal pneumonia in older adults; therefore, the standing committee on vaccination of the Robert Koch Institute (STIKO) recommends a once only vaccination with 23-valent pneumococcal polysaccharide vaccine for all persons aged 60 years and over. Furthermore, the 13-valent pneumococcal conjugate vaccine is also available for administration in adults and is recommended by the STIKO for particular indications. The advantage of the pneumococcal conjugate vaccine is the additional induction of a T-cell dependent immune response that leads to good immunogenicity despite immunosenescence. Initial data from a recent randomized controlled trial, so far only presented at conferences, confirm that the conjugate vaccine also provides protection against non-bacteremic pneumococcal pneumonia, which is not provided by the polysaccharide vaccine. Thus, there are two vaccines for prevention of pneumococcal diseases: one with a broader range of serotype coverage but with an uncertain protection against non-bacteremic pneumococcal pneumonia and another one with less serotype coverage but more effective protection. Vaccination of children with the conjugate vaccine also leads to a rapid decrease of infections by the 13 vaccine serotypes even in adults because of herd protection effects. For prevention of pneumonia in older adults the additional benefit of a concurrent application of influenza vaccine and pneumococcal vaccine should be considered.

BACKGROUND: Physicians in Germany who are not specialized in geriatric medicine often have to make decisions regarding referral of patients for early geriatric rehabilitation. The risk of inadequate patient allocation is due to lack of knowledge or underestimation of the potential benefit of early rehabilitation in reducing a patient's need of care. Particularly the oldest old are affected by those inadequate decisions. MATERIALS AND METHODS: Based on the nationwide database Gemidas Pro, the data sets of ≥ 90-year-old patients were analysed regarding diagnoses, multimorbidity, gender, length of stay, procedures, outcome parameters as nursing personnel regulation (PPR), Barthel index and the Timed Up and Go (TUG) test compared to younger age groups. Data from 85 acute inpatient geriatric institutions during the period from January 2006 to December 2009 were included. RESULTS: Neither the analysis of the diagnosis nor multimorbidity showed relevant differences compared to younger patients. Despite poorer functional status at admission, the ≥ 90 year olds experienced a 25 % increase in the activities of daily living (ADL) measured by PPR, 30 % increase in mobility classification based on the TUG and 59 % increase in ADL measured with the Barthel index. These changes were significantly different. In addition, the length of stay was 18.96 days on average in the group of ≥ 90-year-old patients, which was but not significantly shorter than the length of stay in the group of 70- to 79-year-old (19.7 days) and 80- to 89-year-old patients (19.65 days). CONCLUSION: The analyses show that the oldest old suffer from more severe deficits in functional status on admission in acute geriatric wards compared to younger patient groups. However, on discharge the oldest old show a significant and relevant increase in mobility and ADL without increase in length of stay.

Infections due to pneumococci especially in the elderly are vastly underestimated, e.g., because non-invasive infections such as pneumonia may appear with only few symptoms. Sequential vaccination with the pneumococcal conjugate vaccine PCV13, followed by the 23-valent polysaccharide vaccine, is considered as the best preventive measure for individual protection, even though clinical study data demonstrating the efficacy of this sequence are not yet available. Increase of "awareness" by use of computer-based reminder functions may result in a significant improvement of vaccination compliance.

The aging immune system, so-called immunosenescence, is well documented as the cause of increased infection rates and severe, often complicated course of infections in the elderly with increased morbidity and mortality rates. Furthermore, it can lead to decreased efficacy of vaccination. The administration of more immunogenic vaccines can be beneficial in the elderly. Implementing vaccination recommendations for the elderly by STIKO can reduce burden of infectious diseases by prevention of infection or reduction of severity of infection. The following vaccinations are recommended by STIKO for all persons aged 60 and above: annual influenza vaccination (additionally all nursing home residents independently of age), once only pneumococcal polysaccharide vaccination, completion of tetanus and diphtheria (Td) vaccination as well as regular revaccination. All adults should be vaccinated against pertussis with Tdap vaccine once. Meanwhile, pneumococcal conjugate vaccine is allowed for administration in adults but is not recommended by STIKO yet. A lifelong course of vaccination may help to attenuate the effect of immunosenescence.

Ageing shows a high interindividual and intraindividual variability. Subclinical and clinical cardiovascular diseases accelerate the ageing process in part and in total. This leads to the idea that ageing is a result of a chronic inflammation process and to the term "inflammageing". A variety of biomarkers (e.g. C-reactive protein, interleukin-6, tumor necrosis factor alpha, fibrinogen, albumin and serum amyloid A) are described in this context. Furthermore there is a relationship to changes in the immune system across the lifespan (immunosenescence), viral infections, the occurrence of markers of oxidative stress and genetic changes. At this point in time the role for determining ageing and its use as a prognostic tool seems to be impossible. Whether inflammageing is a valid model for describing the ageing process or is the consequence of other mechanisms needs further discussion.

Depression is one of the most common affective illnesses. The investigation of changeable factors that are associated with depression is an important condition for the establishment of preventive measures. In a cross-sectional study, data on social factors were recorded from 580 geriatric patients of the municipal hospital in Munich. Ordinal logistic regression was used to analyse their association with depression (clinical diagnoses by ICD-10) and depressive symptoms (GDS). The results indicate that the occurrence of depressive symptoms and of depression was associated with less social contacts and less support, even after adjustment for other risk factors (for example, physical and cognitive impairment). This association was more distinct for women (for example, depressive symptoms: moderate versus much contact: OR=2.7; 95% CI: 1.8-4.1) than for men (OR=1.3; 95% CI: 0.7-2.4). Further research is needed to investigate whether women could benefit more than men from programmes promoting social support.

The higher prevalence of depression in specific diseases and older persons is discussed. This prevalence varies greatly according to the method used to collect data. A risk group can only be defined if information on diseases and other influencing factors are collected uniformly. The target diagnoses Parkinson's disease, stroke, myocardial infarction, cancer, diabetes mellitus, chronic pain, multiple infarct syndrome, Alzheimer's and other dementia were recorded from 1208 geriatric patients of the ZAGF municipal hospital in Munich, Germany. Logistic regression was used to identify chronic pain as the main cofactor for an association with depression (clinical diagnoses by ICD-10) and depressive symptoms (via GDS [Geriatric Depression Scale]). This association was also found for multimorbid patients with chronic pain. Impairment of the activities of daily living and the clinical setting were important additional cofactors. Pain patients are therefore at higher risk for depression.

Geriatric care covers a variety of differentiated services and structures, and the well-established system of in- and outpatient treatment has now been expanded to include the day hospital. The 30-bed geriatric day hospital at the "Zentrum für Akutgeriatrie und Frührehabilitation", ZAGF (Center for Acute Geriatric Medicine and Early Rehabilitation) at the Municipal Hospital Munich Neuperlach provides diagnostic and therapeutic services for acute and chronic illnesses with the aim of obviating or shortening hospitalization, helping patients to practise self-help, and preserving social competence. A multi-dimensional interdisciplinary geriatric assessment is used to clarify indications and contraindications, and to plan holistic individual therapeutic strategies.
