Impact of social isolation and coping strategies in older adults with mild cognitive impairment during the covid-19 pandemic: A qualitative study.

OBJECTIVES: The objective of this study was to explore the experiences and feelings of older adults with MCI during the COVID-19 outbreak in Chile and to know what strategies they used to overcome social isolation. METHOD: A qualitative design was used. Ten participants with a diagnosis of MCI took part in this study. All interviews were recorded and coded using thematic analysis. RESULTS: The thematic analysis identified three themes related to the quarantine experience of older adults with MCI diagnosis: (1) Effects of social isolation during the COVID-19 pandemic (2) Believes, feelings and behaviors about the SARS-CoV-2 virus (3) Coping with social isolation/response to difficulties during the pandemic. It was found that older adults with MCI have been mainly psychologically and socially affected by social distancing and isolation, particularly individuals who were alone during COVID-19 outbreak. The only physical dimension negatively affected was the level of activity. Social isolation led to a significant number of negative emotions such as anger, fear of contracting the virus or possibility of contagion for their families, worries and sadness as well as emotional loneliness. It is noteworthy that the majority of participants have used several coping strategies during this challenging time. CONCLUSION: Since social isolation and a sedentary life have been associated with poorer cognition and functionality in people with MCI, a rational plan to both prevent the progression of cognitive decline and to increase social contact, is essential. Special attention must be drawn to maintaining people physically active at home and keeping their daily routine (within the possibilities) and also to ensure social connectedness through technology. Implementation of these measures could potentially reduce negative emotions during the pandemic.

Impact of mind-body interventions in older adults with mild cognitive impairment: a systematic review.

ABSTRACTBackground:Mind-body interventions have been associated with a range of positive outcomes in older adults with mild cognitive impairment (MCI). The aim of the present study was to review the impact of different non-pharmacological programs based on mind-body intervention for older adults with MCI. METHODS: A comprehensive search method as required by the Cochrane Collaboration has been performed through the following databases: Google Scholar, Science Direct, PubMed, PsycINFO, MEDLINE, EMBASE, CINHAL, Cochrane, Ebsco. We included the studies that evaluated the impact of mind-body interventions such as mindfulness or meditation, yoga, Tai Chi and Qigong on cognitive function and everyday functionality of non-hospitalized adults aged 55 years or over with MCI. RESULTS: Nine studies met the inclusion criteria. Results indicated that mind-body interventions improved cognitive function, everyday activities functioning, and mindfulness, as well as resulting in a moderate reduction in fall risk, depression and stress and lower risk of dementia at one year. CONCLUSION: Several mind-body interventions focused broadly on mindfulness, yoga and Tai Chi training have been studied. This review shows that mind-body interventions improved cognitive function and everyday activities functioning, memory, resilience and mindfulness in older adults with MCI. However, the conclusions faced limitations, such as small sample size, heterogeneity of outcome measures, lack of an active control group and absence of long-term follow up. Further high-quality evidence is needed in order to determine whether mind-body interventions are cost-effective for improving cognitive decline in older adults with MCI and for delaying the rapid progression from MCI to Alzheimer or other types of dementia.

Effectiveness of a group-based psychosocial program to prevent depression and anxiety in older people attending primary health care centres: a randomised controlled trial.

BACKGROUND: Evidence about the effectiveness of psychosocial interventions to reduce the incidence of depression and anxiety and promote subjective well-being in older people is limited, particularly in Latin-American countries. This study thus aims to assess a program specifically designed to address this issue in persons aged 65 to 80 and attending primary health care centres. METHOD: Older people who use primary care centres are to be randomly assigned to the program or to a control group. Only independent users will be included; those having had a major depressive disorder or an anxiety disorder in the last 6 months will be excluded. The program is group based; it includes cognitive stimulation, expansion of social support networks and cognitive behaviour strategies. Depressive and anxiety symptoms and disorders, as well as psychological well-being, will be assessed using standardised instruments, once before implementing the program and later, after 18 and 36 weeks. DISCUSSION: Primary care is a setting where interventions to improve mental health can be beneficial. Providing evidence-based programs that work with older people is a priority for public mental health. TRIAL REGISTRATION: A protocol for this study has been registered prospectively at ISRCTN registry on 25 July 2018. Identifier: ISRCTN32235611 .

The impact of COVID-19 on deaths from dementia and Alzheimer's disease in Chile: an analysis of panel data for 16 regions, 2017-2022.

Background: Although several studies have documented the detrimental impacts of global COVID-19 containment measures on individuals with Alzheimer's disease and dementia, a comprehensive analysis of mortality rates for these conditions within the Chilean population is notably lacking. This study aimed to analyze the impact of COVID-19 on mortality rates among individuals with dementia and Alzheimer's disease in Chile. Methods: A retrospective longitudinal cross-sectional study was conducted, considering mortality data for specific mental health conditions during the pre-pandemic and pandemic contexts of COVID-19 in Chile. Quantile regression techniques were employed to analyze the existence of differences between the two periods, while non-observable heterogeneity models for panel data methods were used to evaluate the effect of COVID-19 mortality on crude mortality rates. Findings: Statistically significant differences were observed in the number of deaths from dementia and Alzheimer's disease between the pre-pandemic and COVID-19 pandemic periods. Specifically, crude mortality rates decreased by 10% (-0.10 [95% CI: -0.16, -0.05]) during the pandemic period. Furthermore, the number of deaths from COVID-19 during the pandemic period has a very weak incidence of deaths from mental health conditions such as dementia and Alzheimer's. Specifically, a unit percentage increase in confirmed cases from COVID-19 would result in a 7% (-0.07 [95% CI: -0.13, -0.001]) decrease in the number of deaths from dementia and Alzheimer's. These findings are supported by the application of panel regression with one-way random effects models. Interpretation: The study findings indicate a reduction in mortality rates attributed to dementia and Alzheimer's disease during the COVID-19 pandemic in Chile. This decline could be attributed to the potential underreporting of mental illness as the cause of death during the pandemic period. Several studies have highlighted that approximately 30% of death certificates fail to document the presence of a dementia syndrome. Moreover, the cause of death recorded for individuals with mental health conditions may be influenced by the physician's familiarity with the patient or reflect the prevailing approach to managing end-stage dementia patients. Funding: This work received no funding.

Altered muscle strength and flexibility among a subgroup of women with chronic nonspecific low back pain: Cross-sectional case-control study.

OBJECTIVE: To compare muscle strength and flexibility among a subgroup of women with extension-related chronic nonspecific low back pain (CNLBP) with healthy controls. METHODS: In this case-control study, 32 subjects with and without extension-related CNLBP were tested (n = 16 in each group). Gluteal, abdominal, paravertebral, and hamstring strength, along with hip flexor flexibility and hamstring flexibility were compared between groups. Data were analyzed using the Mann-Whitney test (p < .007). RESULTS: The CNLBP subgroup displayed significantly lower strength of all muscles analyzed (p < .007), with the exception of gluteus medius. The flexibility of the hip flexors and hamstrings were not significantly reduced among the women with CNLBP (p > .007). DISCUSSION: The present study showed that alterations in muscle strength, but not flexibility, partly consistent with those previously hypothesized but not objectively reported, were present among a subgroup of women with extension-related CNLBP. These results may have implications for the selection of therapeutic exercises among this subgroup of people with CNLBP.

The Impact of a Yoga-Based Mindfulness Intervention versus Psycho-Educational Session for Older Adults with Mild Cognitive Impairment: The Protocol of a Randomized Controlled Trial.

BACKGROUND: There is a global agreement in the medical community that a significant proportion of dementia cases could be prevented or postponed. One of the factors behind this agreement comes from scientific evidence showing that mind-body interventions such as mindfulness and yoga for the elderly have been related to a range of positive outcomes, including improved cognition performance in seniors with mild cognitive impairment (MCI). OBJECTIVE: This study aims to evaluate the effectiveness of a yoga-based mindfulness intervention (YBM) versus psychoeducational sessions for older adults with MCI attending Hospital Clinic Universidad de Chile in Santiago. METHOD: Two-arm, individually randomized controlled trial (RCT) will be carried out at Clinical Hospital Universidad de Chile in Santiago. Older people over 60 years with any type of MCI using a score < 21 in the Montreal Cognitive Assessment (MoCA) test and a score of 0.05 in the Clinical Dementia Rating (CDR) Scale; and with preserved activities of daily living will be randomly assigned with an allocation ratio of 1:1 in either the yoga-based mindfulness intervention or the active control group based on the psycho-educational program. People who have performed yoga and/or mindfulness in the last 6 months or/and people with a psychiatric clinical diagnosis will be excluded from the study. Montreal Cognitive Assessment, the Lawton Instrumental Activities of Daily Living Scale (IADL), the Barthel Index (BI), the Pemberton happiness index, the Geriatric Anxiety Inventory (GAI) as well as the Geriatric Depression Scale (GDS-5) will be administered by blinded outcomes assessors before random assignment (Pre-test), the week following the last session of the intervention (post-test), and then after 3- and 6-months follow-up. RESULTS: The YBM intervention protocol based on a video recording has been adapted and designed. This is the first RCT to examine the effects of a yoga-based mindfulness intervention in improving cognitive and physical functions and mental health outcomes for Chilean elderly diagnosed with MCI. It is expected to be implemented as an acceptable and effective non-pharmacological option for older people with MCI. CONCLUSION: Providing evidence-based programs such as preventive therapy for Alzheimer's disease has relevant implications for public mental health services in Chile.

Effect of a 40-weeks multicomponent exercise program and branched chain amino acids supplementation on functional fitness and mental health in frail older persons.

BACKGROUND: The ageing process implies several physiological and psychological changes that hence affect the general health, mood states, and quality of life of older persons. Exercise and adequate nutrition are renowned non-pharmacological strategies that significantly delay and alleviate the adverse consequences of the ageing process. This study aimed to evaluate the effects of branched-chain amino acid (BCAA) supplementation and a multicomponent exercise program (ME) on the physical frailty and mood states of older persons. METHODS: 35 participants (women and men; 83 ± 3 years old) from residential care homes were submitted to a 40-week exercise-washout-retraining intervention (16 weeks of the elastic band based exercise and/or supplementation, 8 weeks of washout, and 16 weeks of multicomponent exercise and/or resupplementing), with or without BCAA supplementation. The experimental groups were: (i) ME plus BCAA supplementation (ME+BCAA); (ii) ME; (iii) BCAA supplementation (BCAA), and (iv) control group (CG). Fried's phenotype was used to assess frailty prevalence. Geriatric Depression Scale (GDS), Profile of Mood State (POMS), Mini-Mental State Examination (MMSE), were used to access mental health and cognition. The Short Physical Performance Battery (SPPB) was used to access functional capacity. Salivary testosterone levels (ST) were also determined to access the anabolic effects of the intervention. RESULTS: Exercise was effective in improving functional capacity and prevented the increase in frailty that occurred in the non-exercising CG, where the frailty scores increased over time (p < 0.01). BCAAs supplement alone had no impact on functional fitness, but in a short time (16 weeks) contributed to diminishing frailty and combined with exercise may have the potential to reduce the effect of a detraining period on functional capacity. Salivary testosterone levels correlated with handgrip strength and could be a useful indicator of susceptibility to frailty. No effects were found for mood states, cognition, and depression. CONCLUSION: This study showed that a long-term exercise program, independent of being multicomponent or strength elastic band-based, was effective in improving functional capacity and prevented an increase in frailty in frail and pre-frail older persons living in residential care homes.

Technology-Assisted Collaborative Care Program for People with Diabetes and/or High Blood Pressure Attending Primary Health Care: A Feasibility Study.

The comorbidity of depression with physical chronic diseases is usually not considered in clinical guidelines. This study evaluated the feasibility of a technology-assisted collaborative care (TCC) program for depression in people with diabetes and/or high blood pressure (DM/HBP) attending a primary health care (PHC) facility in Santiago, Chile. Twenty people diagnosed with DM/HBP having a Patient Health Questionnaire-9 score ≥ 15 points were recruited. The TCC program consisted of a face-to-face, computer-assisted psychosocial intervention (CPI, five biweekly sessions), telephone monitoring (TM), and a mobile phone application for behavioral activation (CONEMO). Assessments of depressive symptoms and other health-related outcomes were made. Thirteen patients completed the CAPI, 12 received TM, and none tried CONEMO. The TCC program was potentially efficacious in treating depression, with two-thirds of participants achieving response to depression treatment 12 weeks after baseline. Decreases were observed in depressive symptoms and healthcare visits and increases in mental health-related quality of life and adherence to treatment. Patients perceived the CPI as acceptable. The TCC program was partially feasible and potentially efficacious for managing depression in people with DM/HBP. These data are valuable inputs for a future randomized clinical trial.

Validation of the Geriatric Anxiety Inventory in Chilean older people.

OBJECTIVE: Currently in Chile there is a lack of validated tools for measuring anxiety in the elderly population. Considering this, the purpose of this study was to validate the Geriatric Anxiety Inventory (GAI) in the country. METHOD: An analysis of the psychometric properties of the GAI was carried out, using a non-clinical sample of 301 older adults in the Metropolitan and Valparaíso regions of Chile. Older people were asked about anxiety, rumination, depression, well-being and sociodemographic data. RESULTS: An excellent internal reliability was obtained with a Cronbach score of 0.931. An adequate convergent validity was observed with the Depression scales (CES-D) (Rho = 0.549, p < .01), Rumination (RSS) (Rho = 0.618; p < 0.01) and Experiential avoiding (Rho = 0.485; p < 0.01). On the other hand, the discriminant validity of the psychological well-being scale presented a negative correlation of Rho = -0.699 (p < 0.01). Finally, and Exploratory Factor Analysis was made, revealing a one-dimensional model of the instrument. CONCLUSION: The Geriatric Anxiety Inventory has very good psychometric properties measuring anxiety in elderly people, being an adequate instrument for the screening of anxiety on this population.

Quality of Life of Elderly People with Severe Intellectual Disabilities in Chile / Calidad de vida en adultos mayores con discapacidades intelectuales severas en Chile / Qualidade de vida para idosos com deficiência intelectual grave no Chile

Introduction: Currently, the concept of the quality of life (QoL) is key to defining health policies aimed at the population with intellectual disability (id). Most QoL studies in this field have been limited to people with id with higher functioning levels. This has resulted in a little interest in evaluating QoL interventions among people with id and a high need for supports, affecting their general well-being and conditioning the care they received. This study seeks to explore the QoL levels of people with severe and profound id and to examine their differences based on some variables. Material and methods: From a quantita-tive-descriptive approach, the San Martín scale, based on the eight-dimensional QoL Model of Schalock and Verdugo, has been used in 201 Chilean people with severe or profound id ages between 60 and 86 years. Results: Data show how most participants have low QoL levels, with self-determination and social inclusion being the most affected dimensions. When comparing the QoL score with sociodemographic variables, differences in the level of support needs and the type of center they are used are observed. Conclusion: Low QoL levels should be carefully considered because of a notable risk that they lead to greater vulnerability situations for this group. Likewise, a higher frequency in the support offered should be advocated, and spaces in which these people operate should be brought as close as possible to the community.

Introducción: actualmente, el concepto de calidad de vida (CdV) es clave para definir políticas de salud dirigidas a personas con discapacidad intelectual (di). La mayoría de los estudios sobre CdV en este campo se han limitado a personas con di más leves. Esto ha derivado en un escaso interés por evaluar las intervenciones sobre CdV en personas con di y grandes necesidades de apoyo, que afectan su bienestar general y condicionan la atención recibida. Este estudio busca explorar los índices de CdV de perso-nas con di severa y profunda, y examinar sus diferencias según distintas variables. Material y métodos: desde un enfoque cuantitativo-descriptivo se ha aplicado la Escala San Martín, basada en el Modelo de CdV de ocho dimensiones de Schalock y Verdugo, a 201 chilenos con di severa o profunda entre los 60 y 86 años. Resultados: los datos muestran cómo la mayoría de los participantes tienen bajos índices de CdV, de los cuales la autodeterminación y la inclusión social son las dimensiones más afectadas. Al comparar la puntuación de CdV con algunas variables sociodemográficas, surgen diferencias según la necesidad de apoyo de los participantes y el tipo de centro del que son usuarios. Conclusión: es necesario prestar atención a los bajos índices de CdV, porque existe un riesgo notable de que conduzcan a mayores situaciones de vulnerabilidad para este grupo. Asimismo, conviene abogar por una mayor frecuencia en los apoyos ofrecidos y acercar lo más posible a la comunidad los espacios en los que se desenvuelven estas personas.

Introdução: atualmente, o conceito de qualidade de vida (QdV) é fundamental para a definição de polí-ticas de saúde voltadas às pessoas com deficiência intelectual (di). A maioria dos estudos de QdV neste campo foi limitada a pessoas com di mais leve. Isso gerou pouco interesse em avaliar intervenções de QdV em pessoas com di e altas necessidades de suporte, afetando seu bem-estar geral e condicionando os cuidados recebidos. Este estudo busca explorar os níveis de QdV de pessoas com di severa e profunda e examinar suas diferenças de acordo com diferentes variáveis. Material e métodos: a partir de uma abordagem quantitativo-descritiva, a Escala de San Martín, baseada no modelo de QdV de Schalock e Verdugo em oito dimensões, foi aplicada a 201 chilenos com di severa ou profunda entre 60 e 86 anos de idade. Resultados: os dados mostram como a maioria dos participantes apresenta baixos níveis de QdV, sendo a autodeterminação e a inclusão social as dimensões mais afetadas. Ao comparar o escore de QdV com algumas variáveis sociodemográficas, surgem diferenças de acordo com o nível de necessidade de apoio dos participantes e o tipo de centro de que são usuários. Conclusão: deve-se atentar para os baixos níveis de QV, pois há um risco notável de que levem a maiores situações de vulnerabilidade para esse grupo. Da mesma forma, é aconselhável advogar por uma maior frequência no apoio oferecido e aproximar os espaços de atuação dessas pessoas o mais próximo possível da comunidade.
