Background: Residents in nursing homes show a high prevalence of the musculoskeletal syndrome sarcopenia and tend not to achieve current physical activity recommendations.

Objective: The aim of this study is to identify differences in physical activity and sedentary behavior of sarcopenic residents compared with nonsarcopenic and presarcopenic residents.

Methods: Sarcopenia assessment was performed among 63 nursing home residents in Baden-Wuerttemberg (D) using the European Working Group on Sarcopenia in Older People 2 specifications. Structured activity sessions (per week), accelerometer-based physical activity (steps/day), and sedentary behavior (percentual/day) were examined. The group comparisons were determined with Kruskal-Wallis tests and Dunn-Bonferroni post hoc tests.

Results: Significant differences were found for number of steps (p = 0.005) and percentual sedentary behavior (p = 0.019). Moreover, steps per day presented significant results in group comparison for no sarcopenia (2824.4 [423-14275]) with probable sarcopenia (1703.9 [118-5663]) and confirmed/severe sarcopenia (1571.2 [240-2392]) (both p = 0.022; |r| = 0.34). Sedentary behavior demonstrated significant differences in groups with no sarcopenia (87.9% [69.1-94.3]) and with probable sarcopenia (91.7% [80.4-9835]) (p = 0.018; |r| = 0.35).

Conclusion: Nonsarcopenic residents demonstrated a higher number of steps and lower sedentary behavior compared with presarcopenic and sarcopenic residents. Increasing steps, reducing sedentary behavior and promoting activities of daily living can contribute to the prevention and treatment of sarcopenia in the nursing home setting.

Background: In order to cognitively and physically activate people with dementia (MMD) in institutional settings, there are numerous touch-based multimedia applications specifically designed for this target group that are actually being used in practice. In contrast, the use of similar applications in domestic settings has been relatively limited.

Aim and method: This study is based on 11 expert interviews guided by questions and examines design options and requirements for application content as well as requirements for study designs to provide evidence of the effectiveness of touch-based multimedia applications for MMD and their caregiving relatives (PA).

Results: There is a high degree of consensus regarding the criteria for requirements for touch-based multimedia applications. Acceptance is highly dependent on user competence, usage practices, experiences and incentive structures; however, there are diverse opinions about their structural and content-related design. The quality of life is mentioned as an essential evaluation parameter for multimedia applications.

Discussion: The highly variable individual life circumstances of MMD and their PAs, along with limited access options and a lack of suitability of the multimedia applications, may be causal factors for their relatively limited use, especially in domestic settings. Daily performance capabilities and individual disease progression pose special requirements for the scientific evaluation and the demonstration of the effectiveness of touch-based multimedia applications.

As an introduction to this special issue on geroscience, the present work focuses on the complexity of disentangling biomolecular mechanisms of aging from biopsychosocial causes of accelerated aging. Due to this complexity, the biomolecular aging hallmarks of frailty and multimorbidity as predominant aging phenotypes in geriatrics reflect single aspects of the aging process. A possible approach to facilitate the integration of geroscience into healthcare might be to consider aging as the dynamic ratio between damage accumulation at the molecular and cellular level and resilience as strategies that prevent or repair such damage. There is a large body of evidence to show that geroscience has the potential to change healthcare; however, reaching a consensus and translating the best tool to measure aging needs more research on 1) the sensitivity of biomarkers to interventions and 2) the relationship between changes in biomarkers and changes in health trajectories.

Background: Poliomyelitis is an infectious disease of the peripheral motor neurons, which predominantly affects children and causes residual palsies. Because of the oral poliomyelitis vaccination started in Germany in 1960 and 1962 and the following rapid decline of the incidence of this infection, the postpolio syndrome in Germany is a disease of older people.

Methods: Since 2008, we have offered a poliomyelitis outpatient consultation at the Center of Geriatrics, Protestant Hospital Göttingen-Weende and have treated 33 patients.

Results: The spectrum of persistent deficits after poliomyelitis ranges from palsy of single extremities to severe disability with (temporary) ventilator dependence. Many patients suffer from scoliosis or shortening of limbs of different degrees, which promotes degenerative diseases of the spinal cord and joints with secondary myelopathy, injury of spinal nerve roots or peripheral nerves or respiratory failure. The postpolio syndrome is characterized by an increase of the functional deficits after decades of compensation. The palsies of 2 of the 33 patients were not caused by poliomyelitis but by myelomeningocele and schizencephaly, respectively.

Conclusion: The motor deficits acquired in childhood enable the majority of the patients to successfully master their lives. Because of the limited compensatory capacities of postpolio patients, even small increases in the severity of the palsy can cause a severe decline of the functional status and an impairment of the ability to live an independent life. In a substantial proportion of patients with the diagnosis poliomyelitis the symptoms are caused by other diseases.

Background: In Germany, different models of orthogeriatric co-management have been implemented in certified geriatric trauma centers. So far, it is not clear how the different models are implemented and what influence the certification has on the structures and processes within the centers. The present study examined the extent of cooperation between surgery and geriatrics and if the quality of care had changed since the certification of the centers.

Methods: In this study 4 guided focus group interviews (FGI) were conducted in different teams of certified geriatric trauma centers in 3 federal states with 16 participants. To specify the content of the FGI, two additional interviews were conducted with system auditors. Both types of interview were analyzed by content analysis.

Results: The certification supported the implementation of structures and processes in the different orthogeriatric models; however, the quality of care and cooperation between surgery and geriatrics depends on the spatial proximity and the orthogeriatric care model in the geriatric trauma centers. Simultaneously, challenges in the area of geriatric syndromes and the recruitment of skilled staff became relevant.

Discussion: The results can help to reflect processes in the certified geriatric trauma centers and to treat geriatric syndromes more effectively. In the future, the challenge will be to establish geriatric care under the existing shortage of skilled staff.

As scientists investigated the molecular mechanisms of the biology of aging, they discovered that these are malleable and can enhance healthy longevity by intervening in the drivers of aging, which are leading to disease, dysfunction and death. These exciting observations gave birth to the field of geroscience. As the mechanisms of aging affect almost all mechanisms of life, detailed molecular mechanistic knowledge must be gained or expanded by considering and integrating as many types of data as possible, from genes and transcripts to socioenvironmental factors. Such a large-scale integration of large amounts of data will in turn profit from "deep" bioinformatics analyses that provide insights beyond contextualizing and interpreting the data in the light of knowledge from databases such as the Gene Ontology. The authors suggest that "deep" bioinformatics, employing methods based on artificial intelligence, will be a key ingredient of future analyses.
