Leisure time physical activity and exercise performance in active older people in rural areas-Comparison of the first and second COVID-19 related lockdown in Germany. PLoS One 2023; 18:e0291560. [PMID: 37708185 PMCID: PMC10501614 DOI: 10.1371/journal.pone.0291560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Accepted: 09/01/2023] [Indexed: 09/16/2023] Open
Abstract
The closure of all sports facilities during the two lockdowns in Germany favoured a reduction of leisure time physical activity during the COVID-19 pandemic. The aim of this study was to compare leisure time physical activity during the 1st and 2nd lockdown and to examine exercise performance before and after resumption of exercise. Leisure time physical activity was measured by the Longitudinal Urban Cohort Ageing Study (LUCAS) functional ability index and energy expenditure in the Minnesota Leisure Time Physical Activity Questionnaire. Participants' exercise performance was extracted from a chip-controlled fitness circuit. Differences were tested for statistical significance using Friedman tests. 35 participants above 60 years were included from the Oldenburg area (20 women, 15 men, mean age and standard deviation 71±6 years). The decline in energy expenditure was higher during the 2nd lockdown (1st lockdown: Median -55.7 kcal.day-1, Q0.25-121.3 kcal.day-1, Q0.75 132.9 kcal.day-1; 2nd lockdown: Median -119.7 kcal.day-1, Q0.25-255.6 kcal.day-1, Q0.75-65.1 kcal.day-1; Friedman test: p<0.001, n = 35, W = 0.262). The time spent in the fitness circuit decreased from lockdown to lockdown as well as the number of participants exercising there. Intense activities were performed during the two lockdowns by only 7 and 3 participants, respectively, and were not resumed by two-thirds of the participants after the 2nd lockdown. During the 1st lockdown, exercise performance on resistance exercise devices increased in most of them, while it decreased by 1 to 7% during the 2nd lockdown. The lockdowns limited leisure time physical activity in older adults. This was more pronounced during the lockdown in winter 2020/2021, when participants engaged less in outdoor activities. Therefore, measures should be taken to maintain physical activity and muscle strength, especially during winter months, with a home-based training, if visiting gyms is not possible.

Abstract
BACKGROUND Falls are a major problem associated with ageing. Yet, fall-risk classification models identifying older adults at risk are lacking. Current screening tools show limited predictive validity to differentiate between a low- and high-risk of falling. OBJECTIVE This study aims at identifying risk factors associated with higher risk of falling by means of a quality-of-life questionnaire incorporating biological, behavioural, environmental and socio-economic factors. These insights can aid the development of a fall-risk classification algorithm identifying community-dwelling older adults at risk of falling. METHODS The questionnaire was developed by the Belgian Ageing Studies research group of the Vrije Universiteit Brussel and administered to 82,580 older adults for a detailed analysis of risk factors linked to the fall incidence data. Based on previously known risk factors, 139 questions were selected from the questionnaire to include in this study. Included questions were encoded, missing values were dropped, and multicollinearity was assessed. A random forest classifier that learns to predict falls was trained to investigate the importance of each individual feature. RESULTS Twenty-four questions were included in the classification-model. Based on the output of the model all factors were associated with the risk of falling of which two were biological risk factors, eight behavioural, 11 socioeconomic and three environmental risk factors. Each of these variables contributed between 4.5 and 6.5% to explaining the risk of falling. CONCLUSION The present study identified 24 fall risk factors using machine learning techniques to identify older adults at high risk of falling. Maintaining a mental, physical and socially active lifestyle, reducing vulnerability and feeling satisfied with the living situation contributes to reducing the risk of falling. Further research is warranted to establish an easy-to-use screening tool to be applied in daily practice.

JMIR Aging 2022; 5:e36872. [PMID: 35972785 PMCID: PMC9428783 DOI: 10.2196/36872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 06/07/2022] [Accepted: 06/27/2022] [Indexed: 12/04/2022] Open
Abstract
Background Falls and the risk of falling in older people pose a high risk for losing independence. As the risk of falling progresses over time, it is often not adequately diagnosed due to the long intervals between contacts with health care professionals. This leads to the risk of falling being not properly detected until the first fall. App-based software able to screen fall risks of older adults and to monitor the progress and presence of fall risk factors could detect a developing fall risk at an early stage prior to the first fall. As smartphones become more common in the elderly population, this approach is easily available and feasible. Objective The aim of the study is to evaluate the app Lindera Mobility Analysis (LIN). The reference standards determined the risk of falling and validated functional assessments of mobility. Methods The LIN app was utilized in home- and community-dwelling older adults aged 65 years or more. The Berg Balance Scale (BBS), the Tinetti Test (TIN), and the Timed Up & Go Test (TUG) were used as reference standards. In addition to descriptive statistics, data correlation and the comparison of the mean difference of analog measures (reference standards) and digital measures were tested. Spearman rank correlation analysis was performed and Bland-Altman (B-A) plots drawn. Results Data of 42 participants could be obtained (n=25, 59.5%, women). There was a significant correlation between the LIN app and the BBS (r=–0.587, P<.001), TUG (r=0.474, P=.002), and TIN (r=–0.464, P=.002). B-A plots showed only few data points outside the predefined limits of agreement (LOA) when combining functional tests and results of LIN. Conclusions The digital app LIN has the potential to detect the risk of falling in older people. Further steps in establishing the validity of the LIN app should include its clinical applicability.

Falling Short: The Contribution of Central Insulin Receptors to Gait Dysregulation in Brain Aging. Biomedicines 2022; 10:biomedicines10081923.

Abstract
Insulin resistance, which manifests as a reduction of insulin receptor signaling, is known to correlate with pathological changes in peripheral tissues as well as in the brain. Central insulin resistance has been associated with impaired cognitive performance, decreased neuronal health, and reduced brain metabolism; however, the mechanisms underlying central insulin resistance and its impact on brain regions outside of those associated with cognition remain unclear. Falls are a leading cause of both fatal and non-fatal injuries in the older population. Despite this, there is a paucity of work focused on age-dependent alterations in brain regions associated with ambulatory control or potential therapeutic approaches to target these processes. Here, we discuss age-dependent alterations in central modalities that may contribute to gait dysregulation, summarize current data supporting the role of insulin signaling in the brain, and highlight key findings that suggest insulin receptor sensitivity may be preserved in the aged brain. Finally, we present novel results showing that administration of insulin to the somatosensory cortex of aged animals can alter neuronal communication, cerebral blood flow, and the motivation to ambulate, emphasizing the need for further investigations of intranasal insulin as a clinical management strategy in the older population.

Abstract
Falls have a considerable impact on the functional prognosis of older adults. The main focus of this multicenter, retrospective, observational study was to examine the prevalence of falls in Spanish people aged 65−80 years still living at home. The secondary aims included examining the overall sociodemographic and clinical variables associated with a history of falls and then stratifying these findings by sex. We also aimed to determine the differences between sexes with regard to the history and consequences of falls and to evaluate associations between fall history and functional performance tests. The 747 older adults had all participated in the otago exercise program, which is a progressive home program of strength, balance, and endurance exercises. They were recruited by nurses in 21 primary care centers in 10 Spanish provinces between September 2017 to December 2018. The participants' mean age was 72.2 (SD: 4.3) years, and 67% were women. We recorded sociodemographic and clinical variables, functional performance test results, and any falls and/or injuries in the last 12 months. We found that 32% had fallen, 36% of those had fallen more than once, and 48% had sustained injuries when they fell. The bivariate analysis showed that women had more than twice the odds of falling than men and that living alone and being obese or overweight increased the odds of a fall, although living alone was not associated with falls in the multivariable analysis. Our results could guide the development of risk‐specific fall prevention programs to prevent disabilities in older people.

Abstract
INTRODUCTION Social isolation and lifestyle changes provoked by the COVID-19 pandemic have negatively affected the level of physical activity of the elderly people. OBJECTIVE To evaluate the available evidence related to the level of physical activity (PA) of elderly people during the COVID-19 pandemic. METHODS This is a systematic review, registered on PROSPERO (CRD42021241116), which included cross-sectional and cohort studies. Embase, Pubmed, Cochrane, Web of Science and Scopus databases were used to search for the studies. Finally, the New Castle-Ottawa Quality Assessment scale was used to measure the quality of the studies. RESULTS 25 studies were found, being 14 cross-sectional and 11 cohort studies. The studies showed that the elderly population was highly affected in relation to the level of physical activity and lifestyle during restrictions, quarantine and lockdowns caused by the COVID-19. There was a significant reduction in physical activity levels, leading to declines in physical fitness and increased sedentary lifestyle, factors directly related to the increase in frailty in this population. CONCLUSION The level of physical activity in the elderly population decreased during the quarantine period of COVID-19 worldwide. Strategies to maintain physical condition must be encouraged with physical exercises that meets the needs of the elderly in the current pandemic scenario, in order to maintain and improve the health of this population.

Abstract
Abstract Introduction: Physical inactivity negatively impacts the functional status of the elderly during aging. Objective: To describe the activity and participation profile of physically inactive elderly and to investigate associated factors. Methods: A cross-sectional study with physically inactive elderly, aged ≥ 60 years, both sexes, with good cognitive function and independent gait. Personal factors, clinical history, history of falls in the last year, and identification of activity and participation profiles were investigated. Nonparametric statistical tests (SPSS 20.0) were performed, considering p < 0.05 significant. Results: The elderly (n = 36) had a mean age of 72.5 years (±7.7). Most were women (78%), with one to four years of education (69%), retired (72%), referring episodes of falling (58%) and affected by two to four comorbidities (53%). In the activities and participation profile, most of the physically inactive elderly presented mild problems for: crawling, kneeling, squatting, walking long distances, walking on different surfaces, walking around obstacles, climbing, and using public transportation. However, kneeling, squatting, walking on different surfaces, and climbing represented higher percentages of elderly who presented some problem. The advancement of age (p = 0.045), female sex (p = 0.022), episodes of falls (p = 0.037), and comorbidities (p = 0.031) were identified as factors that can impact functioning. Conclusion: The physically inactive elderly presented a mild problem in activities and participation items that are more related to strength and walking. Elderly aged over 70, female, with episodes of falls and comorbidities were significantly associated with reduced or impaired functioning.

Resumo Introdução: A inatividade física impacta negativamente a funcionalidade dos idosos durante o envelhecimento. Objetivo: Descrever o perfil de atividade e participação de idosos inativos fisicamente e investigar fatores associados. Métodos: Estudo transversal com idosos inativos fisicamente, ≥ 60 anos, ambos os sexos, boa função cognitiva e independentes na marcha. Foram investigados fatores pessoais, história clínica, histórico de quedas no último ano e identificação do perfil de atividade e participação. Foram realizados testes estatísticos não paramétricos (SPSS 20.0), considerando p < 0,05. Resultados: Os idosos (n = 36) apresentaram média de 72,5 anos (± 7,7). A maioria era mulher (78%), com escolaridade de um a quatro anos de estudo (69%), aposentados (72%), referindo episódios de queda (58%) e acometidos por duas a quatro comorbidades (53%). No perfil de atividades e participação, a maioria dos idosos inativos fisicamente apresentaram problema leve para os itens: engatinhar, ajoelhar-se, agachar-se, andar longas distâncias, andar sobre superfícies diferentes, andar desviando-se de obstáculos, subir e utilizar transporte público. Entretanto, ajoelhar-se, agachar-se, andar sobre superfícies diferentes e subir compreendem maiores percentuais de idosos que apresentaram algum problema. Idade avançada (p = 0,045), sexo feminino (p = 0,022), episódios de quedas (p = 0,037) e presença de comorbidades (p = 0,031) foram identificados como fatores que podem impactar na funcionalidade. Conclusão: Idosos inativos fisicamente apresentaram problema leve nos itens das atividades e participação que estão mais relacionados à força e ao andar. Idosos com mais de 70 anos, do sexo feminino, com presença de episódios de quedas e de comorbidades, apresentaram associação significativa com a funcionalidade reduzida ou prejudicada.

Abstract
BACKGROUND Central nervous system (CNS) germ cell tumors (GCTs) are neoplasms predominantly arising in pediatric and young adult populations. While germinomas generally respond to chemotherapy and radiation, non-germinomatous GCTs (NGGCTs) require more intensive treatment. This study aimed to determine whether 12p gain could predict the prognosis of CNS GCTs. METHODS Eighty-two CNS GCTs were included in this study. The 12p gain was defined by an additional 12p in the background of potential polyploidy or polysomy. Cases were analyzed using an Illumina methylation 450K array for copy number investigations and validated by fluorescence in situ hybridization (FISH). RESULTS A 12p gain was found in 25-out-of-82 cases (30%) and was more frequent in NGGCTs (12% of germinoma cases and 50% of NGGCT cases), particularly in cases with malignant components, such as immature teratoma, yolk sac tumor, choriocarcinoma, and embryonal carcinoma. 12p gain and KIT mutation were mutually exclusive events. The presence of 12p gain correlated with shorter progression-free (PFS) and overall survival (OS) (10-year OS: 59% vs 94%, with and without 12p gain, respectively, P = 0.0002), even with histology and tumor markers incorporated in the multivariate analysis. Among NGGCTs, 12p gain still had prognostic significance for PFS and OS (10-year OS: 47% vs. 90%, respectively, P = 0.02). The 12p copy number status was shared among histological components in mixed GCTs. CONCLUSIONS 12p gain may predict the presence of malignant components of NGGCTs, and poor prognosis of the patients. It may be associated with early tumorigenesis of CNS GCT.

Abstract
Background: Sarcopenia has a high prevalence in older adults and is associated with chronic aggravations to health, so therefore it is important to identify older adults who are affected by sarcopenia in order to establish preventative strategies or early interventions.Objective: To estimate the prevalence of probable sarcopenia and verify its association with cognitive impairment, fear of falling, depressive symptoms and health self-perception in community-dwelling older adults.Methods: A cross-sectional study with simple random sampling including 306 older adults of both genders. The outcome variable was probable sarcopenia evaluated by the Five times sit-to-stand test (5XSST) considering probable sarcopenia when the measured time was > 15 seconds, following the recommendation of the European Working Group on Sarcopenia in Older People. The predictor variables were cognitive impairment, fear of falling, depressive symptoms and self-perception of health. Multivariate Logistic Regression was performed to verify associations between the variables.Results: The prevalence of probable sarcopenia was 50.00%. The older adults had significantly higher chances of presenting probable sarcopenia when displaying cognitive impairment (OR 2.49; 95%CI 1.46-4.24), fear of falls (OR 4.23; 95%CI 2.51-7.12), depressive symptoms (OR 2.20; 95%CI 1.32-3.67), poor (OR 2.48; 95%CI 1.19-5.16) and fair self-perception of health (OR 2.11; 95%CI 1.22-3.63) when compared to those who did not have the same conditions.Conclusion: The prevalence of probable sarcopenia in this study was 50.00%, and was associated with the presence of depressive symptoms, cognitive impairment, fear of falls and negative self-perception of health.
