The objective of the present study was to analyze the psychometric properties of a life satisfaction scale in older Peruvian adults using an exploratory graph analysis (EGA) approach. A total of 407 older adults aged between 60 and 95 years (M = 69.5; SD = 6.7) from three comprehensive elderly care centers (CIAMs) in Lima, Peru, were recruited. A non-probabilistic convenience sampling was used. The Satisfaction with Life Scale (SWLS) was analyzed using EGA with the Gaussian GLASSO model to assess its dimensionality and structural consistency. The relationship with other variables was analyzed using scales such as the GAD-7 and PHQ-9. The network structure of the SWLS indicates a single dimension. Additionally, network loadings (nodes) were examined, showing high values (>0.35) for most items except item 1, which had a moderate loading (>0.25). Structural reliability showed that a single dimension was identified 100% of the time. The post hoc CFA considering the unidimensional network structure obtained through EGA showed satisfactory fit (χ2/df = 3.48, CFI = 0.96, TLI = 0.92, SRMR = 0.02, RMSEA = 0.07 [90% CI 0.05, 0.08]). Finally, internal consistency reliability was acceptable (ω = 0.92). The SWLS measure is robust and consistent. These findings are a valuable reference for advancing research on aging in Peru, as they provide a practical, valid, and reliable measure.

Aging is a natural, complex, and individual process that focuses on the progressive decay of the body and a decrease in cell function that begins in approximately the sixth decade of life and ends with death. Current scientific evidence shows that the aging process is mostly related to genetic load and varies because of the environment. Therefore, aging can be adjusted through the intervention of factors that control homeostasis in genetic, biochemical, and immunological processes, including those involving the gut microbiota. Indeed, the diversity of the gut microbiota decreases during aging, based on the presence of modifications in the hormonal, immunological, and operational processes of the gastrointestinal tract. These modifications lead to a state of dysbiosis. However, altering bacterial communities remains complicated due to the great diversity of factors that influence their modification. Alterations caused by the aging process are known to foster dysbiosis and correspond to conditions that determine the degree of frailty in senior citizens. Consequently, the microbial structure can be used as a biomarker for geriatric care in the promotion of healthy aging.

The global increase in dementia cases highlights the urgent need for effective treatment and care strategies. The aim of this study was to evaluate the effects of group reminiscence therapy on cognitive function, subjective well-being, and behavioral and psychological symptoms of dementia (BPSD) in older adults with moderate to severe dementia. A pre-post comparative design was used, with 49 participants receiving eight group reminiscence therapy sessions over 4 weeks. Baseline, one-week, and one-month postintervention assessments were conducted using the Hasegawa Dementia Scale-Revised (HDS-R), the Neuropsychiatric Inventory-Nursing Home Version (NPI-NH), and the Philadelphia Geriatric Center Morale Scale (PGC Morale Scale). The results showed no significant improvement in HDS-R scores, but significant improvements in PGC Morale Scale (p = 0.0417) and NPI-NH scores (p = 0.00226), indicating improved well-being and reduced BPSD. These findings suggest that group reminiscence therapy is effective in improving BPSD. Future research should focus on extending the duration of the intervention, including different populations, and combining group reminiscence therapy with other therapeutic approaches to fully determine its long-term benefits and mechanisms. Research on its cost-effectiveness and cultural applicability could further validate and improve the use of group reminiscence therapy in diverse care settings.

Age-related declines in the musculoskeletal system may place additional demands on the lumbar spine during everyday activities such as walking. This study aimed to investigate age-related differences in the functional demand (FD) of walking on the lumbar spine in older and younger adults. A motion analysis system with integrated force plates was used to acquire kinematic and kinetic data on 12 older (67.3 ± 6.0 years) and 12 younger (24.7 ± 3.1 years) healthy men during walking at a self-selected speed along a 10 m walkway. Isokinetic dynamometry was used to acquire the maximal joint moment capacity of the lumbar spine. The FD of the lumbar spine was calculated as the muscle moment during key phases of the gait cycle (GC) relative to the maximum moment capacity of the lumbar spine. The difference in FD between age groups was not significant (p = 0.07) and there were no significant differences between the young group (YG) and older group (OG) for any individual phase in the GC. Despite the lack of statistical significance, the results indicate that a practical difference may exist, as walking was approximately 20% more functionally demanding on the lumbar spine in the OG compared to the YG. Therefore, older adults may employ modified gait strategies to reduce mechanical load whilst walking to fall within the limits of their maximal force-producing capacity in the lumbar spine, which may have implications for injury risk.

The number of patients hospitalized with dementia is increasing, but one symptom, apathy, tends to be overlooked and unaddressed. Thus, this study determines how nurses certified in dementia nursing engage with older patients with dementia who exhibit apathy during hospitalization. A qualitative study using semi-structured interviews with 10 dementia care nurses in Japan was conducted. Through conventional content analysis, 10 categories were generated. They included (1) initiating patient engagement when their physiological or daily-life problems become more pronounced, (2) assessing and identifying the causes of decreased motivation from multiple perspectives, (3) assessing patients from multiple perspectives to determine the best way to start supporting them, (4) providing reassurance through basic dementia care, (5) incorporating pleasant stimuli into the hospital environment, (6) providing care based on patients' circumstances and abilities by collaborating with multiple professionals. Nurses initiate involvement with patients when their daily life problems become more pronounced. They conduct comprehensive assessments from multiple perspectives and collaborate with other professionals to ensure patient care and safety. They also extend their support to patients' families and maintain long-term involvement. Apathetic older patients benefit from basic nursing care practices and a patient-centered approach, which do not require specialization or additional costs and resources.

In the last decades, the scientific interest in ageing has increased due to the progressive ageing of the global population and due to the importance of guaranteeing the elder people and the next generations a good quality of life and biopsychological well-being. However, nowadays, there is not a common and accepted definition of ageing. This situation may refer to the complexity and relevance of the ageing topic and it means that the concept of ageing needs to be understood in a deeper way as a multidimensional and complex process that includes different elements distinctive. The main goal of this review is to explore the definitions and conceptual models of ageing according to a psychological point of view, through a biopsychosocial approach, that integrates biological, psychological, and social aspects with the main goal of a better understanding of the complexity of the process itself.

Methods: We conducted a review of the literature through PubMed, Scopus, Web of Science and Google Scholar databases, and we followed the PRISMA-ScR guidelines, analysing papers written in English between 2002 and 2023.

Results: The review showed different conceptual models of ageing, including Rowe and Kahn's successful ageing model, the World Health Organization's models, and others like the "Selection, Optimization and Compensation" Model. Also, the determinants and predictors of ageing have been analysed highlighting the individual variability and the multidimensional nature of ageing. The geographic diversity of the included studies allowed for the analysis of cultural, socioeconomic, and environmental differences in the conceptualisation of ageing.

Conclusions: The results emphasise the importance of targeted interventions and programs aimed at promoting well-being during ageing, considering the complexity and multidimensionality of the ageing process.

Owing to increasing super-aging societies, older adults will be encouraged to continue working. Although demand exists for older adults to continue working in Japanese society, the enabling factors have not been clarified. This study aimed to clarify (1) the life functions that affect the working status among younger-older adults who continue to work and those who do not via the Kihon Checklist (KCL) and (2) examine whether the number of areas of difficulties in daily functions of the KCL affected older adults' employment status. This cross-sectional study involved 5386 older men and women aged 65 years or older in one city in Japan. Employment status and the seven domains of the Kihon Checklist (KCL) were analyzed. The KCL items related to employment status were the physical (odds ratio = 2.46, p < 0.01), socialization (odds ratio = 1.95, p < 0.01), and mood domains (odds ratio = 1.29, p < 0.01). Furthermore, the odds ratio increased to 2.06 when three or more domains were applicable. To remain employed, one must be physically and mentally healthy. Furthermore, since the risk of non-employment increased when one KCL domain was applicable, a broader assessment of life functions is necessary.

This study investigated the effects of oral nutritional supplements (ONSs) along with dietary counseling (DC) in community-dwelling older adults at risk of malnutrition. In this randomized controlled trial, 196 older adults who were at risk of malnutrition, as identified by the Malnutrition Universal Screening Tool (MUST) were randomly assigned to receive ONSs twice daily with DC (intervention) or DC-only (control) for 60 days. Primary outcome was change in body weight from baseline to day 60. Nutritional status, energy, and macronutrient intakes were measured. A significant larger weight gain was observed in the intervention compared to the control from baseline to day 60 (1.50 ± 0.22 kg, p < 0.0001). The intervention group also showed a significantly greater increase in weight at day 30 (p < 0.0001). Intakes of energy and macronutrients were significantly higher in the intervention group compared to the control group at both days 30 and 60 (all p < 0.0001). The odds of achieving better nutritional status were significantly higher in the intervention group than in the control group (OR:3.9, 95% CI: 1.9, 8.2, p = 0.0001). ONS supplementation combined with DC significantly improved body weight and nutritional outcomes in community-dwelling older adults at risk of malnutrition.

This observational study aimed to identify predictors of kinesiophobia and examine its correlation with early functional outcomes in TKA recipients. On the first and fifth postoperative days (POD1 and POD5), we evaluated pain using the International Pain Outcomes Questionnaire (IPO-Q) and created multidimensional pain composite scores (PCSs). The Total Pain Composite Score (PCStotal) assesses the overall impact of pain, taking into account outcomes of pain intensity, pain-related interference with function, and emotions and side effects. Functional status on POD 5 was determined by the Barthel index, 6 min walking test, and knee range of motion. Kinesiophobia was assessed on POD5 using the Tampa Scale for Kinesiophobia (TSK). Among 75 TKA patients, 27% exhibited kinesiophobia. The final regression model highlighted PCStotal on POD5 (OR = 6.2, CI = 1.9-19.9), PCStotal (OR = 2.1, CI = 1.2-3.8) on POD1, and the intensity of chronic pain before surgery (OR = 1.4, CI = 1.1-2.1) as significant kinesiophobia predictors. On POD5, those with kinesiophobia showed increased dependency, slower gait, and poorer knee extension recovery. This study emphasizes the need to identify and address kinesiophobia in TKA patients for better functional outcomes and recovery. Additionally, it is vital to assess different domains of pain, not just pain intensity, as it can lead to kinesiophobia development.

Little is known about the healthy aging of the circadian timing system under natural living conditions. This study explores changes in the circadian rhythm of distal skin temperature (DST) with aging and relates these changes to sleep-wake timing and environmental influences. DST, sleep-wake timing, 24-h light exposure, and physical activity were measured and averaged over seven consecutive days using temperature sensors, actigraphy with a light meter, and sleep diaries in 35 healthy older women (60-79 years) and 30 young women (20-34 years). Circadian rhythm characteristics, describing strength (amplitude) and timing (acrophase) of the DST rhythm, were calculated using cosinor analysis. The older adults displayed an 18-19% smaller amplitude and a 66-73 min earlier acrophase (peak time) for DST rhythm than the young adults, indicating a weaker and phase-advanced DST rhythm. The phase advance for DST was not due to an earlier evening increase, but to a shorter nocturnal plateau period. Daytime light exposure inversely affected strength (amplitude) but not phasing of the DST rhythm in older adults. The DST rhythm was 3.5 times more advanced than the sleep-wake rhythm, showing an altered phase relationship (phase angle) between both rhythms with aging. The phase angle was more heterogeneous among older adults, showing differential aging. The phase advance for DST rhythm and the altered and heterogeneous phase relationship between DST and sleep-wake rhythms were not related to ambient light exposure and the physical activity of older adults. This suggests that healthy aging of the circadian system might be due to endogenous mechanisms such as an internal rearrangement rather than external influences.
