Understanding the Role of Oxidative Stress in Platelet Alterations and Thrombosis Risk among Frail Older Adults.

Frailty and cardiovascular diseases are increasingly prevalent in aging populations, sharing common pathological mechanisms, such as oxidative stress. The evidence shows that these factors predispose frail individuals to cardiovascular diseases but also increase the risk of thrombosis. Considering this background, this review aims to explore advances regarding the relationship between oxidative stress, platelet alterations, and cardiovascular diseases in frailty, examining the role of reactive oxygen species overproduction in platelet activation and thrombosis. The current evidence shows a bidirectional relationship between frailty and cardiovascular diseases, emphasizing how frailty not only predisposes individuals to cardiovascular diseases but also accelerates disease progression through oxidative damage and increased platelet function. Thus, oxidative stress is the central axis in the increase in platelet activation and secretion and the inadequate response to acetylsalicylic acid observed in frail people by mitochondrial mechanisms. Also, key biomarkers of oxidative stress, such as isoprostanes and derivate reactive oxygen metabolites, can be optimal predictors of cardiovascular risk and potential targets for therapeutic intervention. The potential of antioxidant therapies in mitigating oxidative stress and improving cardiovascular clinical outcomes such as platelet function is promising in frailty, although further research is necessary to establish the efficacy of these therapies. Understanding these mechanisms could prove essential in improving the health and quality of life of an aging population faced with the dual burden of frailty and cardiovascular diseases.

Social Outbreak in Chile, and Its Association with the Effects Biological, Psychological, Social, and Quality of Life.

The World Health Organization has defined collective violence as the instrumental use of violence by people who identify themselves as members of a group against other individuals and have political, economic, or social objectives. In Chile, the "Social Outbreak" was used to describe an episode of collective violence, which began on October 18, 2019, triggered by a multitude of socioeconomic and political factors, with protests and mobilizations in the country's large and small cities; in central, commercial, and residential areas, that lasted for several months, affecting a large part of the population. The objective of the present study was to associate the social outbreak in Chile with its biological, psychological, and social effects on people's health and quality of life, as well as its characteristics in terms of exposure, proximity, type, and frequency. This was a cross-sectional study with non-probabilistic national-level sampling, conducted from 28 November 2019, to 3 March 2020. The instrument had four sections. A total of 2651 participants answered the survey; 70.8% were female, and the mean age was 35.2. The main disturbances perceived were protests (70.9%), alarm sounds (68.1%), shooting sounds (59.0%), and tear gas bombs (56.9%). When quantifying the magnitude of these associations, people who had a medium exposure have a higher probability (OR: 1.99, CI: 1.58; 2.50) of suffering three or more biological effects than people that have a low exposure, while people with higher exposition have a 4.09 times higher probability (CI: 3.11; 5.38). A similar pattern was observed regarding psychological effects, although social effects were primarily experienced by those with high exposure. Social networks, TV, and radio were the most used media among people who perceived a greater effect. People who lived, worked, or shopped near the disturbance's areas show a higher proportion negative effect.

Social outbreak and its association with insomnia and daytime sleepiness in Chile.

Objectives: To associate the effects of the social outbreak with insomnia and daytime sleepiness according to the distance from the riots. Material and Methods: Cross-sectional analytical study; a non-probabilistic sampling was carried out at a national level. The Google Forms tool was used; a document was submitted using a national database. The instrument consisted of four sections: socio-demographic data, biopsychosocial symptoms, insomnia severity index (ISI), and the Epworth sleepiness scale (ESS). The data were analyzed using descriptive statistics and the zero-inflated negative binomial model. Results: Of a total of 2,532 surveyed people, 29% were male; 43% was younger than 30 years old. The 50% of the sample suffers from sleepiness and 71% shows some type of insomnia. The marginal effects of the zero-inflated negative binomial model show that women, people aged 51 or older, who are neither studying a healthcare degree nor working in the healthcare sector, that are exposed to 4 or more hours per day to the news and that live in areas near or very near the riots, have significantly higher ISI (marginal effect 1.356, SE 0.381, p-value 0.000) and ESS scores (marginal effect 0.693, SE 0.320, p-value 0.030). To live/work in rioting areas has the greater marginal effect compared to other determinants. Finally, neither employment status nor educational level are associated with significant effects in the aforementioned scales. Conclusion: The riots occurred during the social outbreak of October 2019 in Chile had an effect on insomnia and daytime sleepiness. Particularly, to live/work in rioting areas has the greater marginal effect compared to other determinants.

Effects of a Structured Multicomponent Physical Exercise Intervention on Quality of Life and Biopsychosocial Health among Chilean Older Adults from the Community with Controlled Multimorbidity: A Pre-Post Design.

Structured multicomponent physical exercise (PE) for older adults, with a combination of strength, aerobic, flexibility, and balance exercises, has been shown to have benefits for physical, cognitive, social, and metabolic functioning, as well as counteracting chronic pathologies and geriatric syndromes. However, little is known about the effect of these interventions in Chilean older adults. Our objective was to determine the effect of a structured multicomponent PE intervention on the quality of life (QoL) and biopsychosocial factors of community-living older adults. We conducted a pre-post intervention without control group, with a face-to-face structured multicomponent PE intervention (cardiovascular, strength/power, flexibility, static and dynamic balance, other psychomotor components, and education), based on FITT-VP principles (frequency, intensity, type, time, volume, and progression of exercise), at moderate intensity, 60 min per session, three times per week, and 12 weeks in duration, among 45 persons with an average age of 70.74 years. Participants were evaluated at the beginning and end of the intervention with different instruments of comprehensive gerontological assessment (CGA). Post intervention, participants (83.70% average attendance) significantly improved scores in QoL, biological and biopsychosocial frailty, sarcopenia, functionality in basic, instrumental, and advanced activities of daily living, dynamic balance, cognitive status and mood, systolic and diastolic blood pressure, weight, body mass index, strength and flexibility clinical tests of lower and upper extremity, aerobic capacity, agility, and tandem balance. The indication and prescription of structured multicomponent PE based on FITT-VP principles, as evaluated with the CGA, improved the QoL and biopsychosocial health of older adults. This intervention could serve as a pilot for RCTs or to improve PE programs or services for older adults under the auspices of existing public policy.

[Effects of physical exercise on sleep quality, insomnia, and daytime sleepiness in the elderly. A literature review]. / Efectos del ejercicio físico sobre la calidad del sueño, insomnio y somnolencia diurna en personas mayores. Revisión de la literatura.

The ageing process alters the stages of sleep, and the elderly that have this problem tend to be prescribed pharmacological treatment. This has long term side effects and results in increased health costs. On the other hand, frequent or regular physical exercise could be an overall superior alternative, due to its multifactorial effects. It is also less expensive, thus more affordable and accessible. Furthermore, these benefits could be extrapolated to the quality of sleep. Taking this into account the purpose of this paper is to establish the proper amount of physical exercise using the FITT (frequency, intensity, time, type of exercise) principle, and its effect on the quality of sleep, insomnia, and daytime sleepiness in the elderly. This could lead us to a paradigm shift in the treatment of sleep disorders, and also may constitute an alternative method for treating the elderly.

Consumo de lácteos y asociación con el exceso de peso en adultos chilenos / Dairy consumption and association with excess weight in chilean adults

Fundamentos: El objetivo de este estudio es asociar el consumo de lácteos con el índice de masa corporal (IMC) en adultos chilenos. Métodos: Estudio analítico transversal, se evaluaron adultos sanos de 18 años en adelante, en diferentes regiones del país. A los 2776 participantes se les aplicó una encuesta de hábitos alimentarios (frecuencia de consumo), encuesta de actividad física (cumple o no con 150 min /semana), de hábito tabáquico (consumo o no consumo) y se les realizaron mediciones antropométricas (peso y estatura). Resultados: Se observaron correlaciones negativas entre la frecuencia de consumo de lácteos con peso (p<0,001) e IMC (p<0,001). Al comparar el tercil de mayor consumo vs el tercil de menor consumo de lácteos, el grupo de mayor consumo presentaba un significativo menor peso e IMC y una mayor puntuación de alimentación, vs el tercil de menor consumo en <30 años (<0,001), pero no en los otros grupos etarios. Finalmente, la ingesta de lácteos se asociaba con menor peso, tanto en el modelo crudo, como en el modelo 1 (OR:0,623; IC95% 0,514-0,755), sin embargo, en el modelo 2 perdía esta asociación (OR:0,934; IC 95% 0,739- 1,181). Conclusiones: El tercil de mayor consumo de lácteos presenta un menor peso, IMC y mayor puntuación en alimentación saludable. Sin embargo, al realizar las asociaciones finales, el consumo de lácteos se muestra como un factor protector frente al exceso de peso solo en los primeros 2 modelos. (AU)

Background: The objective of this study is to associate dairy consumption with body mass index (BMI) in adults in Chile. Methods: Cross-sectional analytical study, the participants correspond to 2276 healthy adults of 18 years or older, in different regions. Each participant answers a survey which includes an eating habit questionnaire (consumption frequency), a physical activity questionnaire (complies or not with 150 min / week), and a smoking habit questionnaire (consumption or non-consumption). This data is complemented with direct measurement of weight and height. Results: Negative correlations were observed between the frequency of dairy consumption with weight (p<0.001) and BMI (p<0.001). When comparing the tertile with the highest vs. the tertile with the lowest consumption of dairy products, the group with the highest consumption has a significantly lower weight, BMI and higher food score than the tertile with the lowest consumption in those <30 years (<0.001), but not in the other age groups. Finally, dairy intake is associated with lower weight, both in the raw model and in model 1 (OR:0.623; CI95% 0.514-0.755), however, in model 2 this association is lost (OR:0.934 ; CI95% 0.739-1.181). Conclusions: The tertile with the highest consumption of dairy products has a lower weight, BMI and a higher score in healthy eating, however, when making the final associations, the consumption of dairy products is shown as a protective factor against excess weight only in the first 2 models.

Inter-University Network for Healthy Aging, Latin America and the Caribbean (RIES-LAC): a university contribution to the Decade of Healthy Aging / Rede interuniversitária para o envelhecimento saudável, América Latina e Caribe (RIES-ALC): uma contribuição universitária para a década do envelhecimento saudável / Red interuniversitaria de envejecimiento saludable, Latinoamérica y Caribe (RIES-LAC): un aporte universitario a la década del envejecimiento saludable

A população mundial está envelhecendo e a América Latina e o Caribe (ALC) não são exceção. Atualmente, 8% da população da ALC tem mais de 65 anos e prevê-se que esse número aumente para 30% até 2050. Sabe-se que o processo de envelhecimento envolve alterações moleculares, fisiológicas, funcionais, psicoafetivas e sociais. Todos envelhecemos, a questão é envelhecer com saúde. Como nem sempre é esse o caso, a Organização Mundial da Saúde (OMS) declarou esse período (2021-2030) como a Década do Envelhecimento Saudável. A Década é uma iniciativa global de colaboração de diferentes setores e partes interessadas (governos, sociedade civil, organizações internacionais, profissionais, instituições universitárias, meios de comunicação social e setor privado) para melhorar a vida de pessoas idosas, suas famílias e comunidades. A colaboração centra-se em quatro pilares de ação estreitamente interligados: mudar a forma como pensamos, sentimos e agimos em relação à idade e ao envelhecimento; garantir que as comunidades promovam as capacidades dos idosos; fornecer cuidados integrados e centrados nas pessoas e serviços de saúde primários que respondam às necessidades dos idosos; e fornecer acesso a cuidados de longo prazo para idosos que deles necessitem.

The world's population is aging, and the Latin America and the Caribbean (LAC) region is no exception. Currently, 8% of the LAC population is over 65 years old, and this number is estimated to increase to 30% by 2050. The aging process is known to involve molecular, physiological, functional, psychosocial, and social changes. We all age; the point is to age healthily. As this is not always the case, the World Health Organization (WHO) declared the period from 2021 to 2030 as the Decade of Healthy Aging. The Decade is a global collaboration involving diverse sectors and stakeholders (governments, civil society, international organizations, professionals, academic institutions, the media, and the private sector) to improve the lives of older people, their families, and communities. The collaboration is centered on four closely interconnected pillars of action: changing how we think, feel, and act towards age and aging; ensuring that communities foster the abilities of older people; providing person-centered integrated care and primary health services responsive to older people; and providing access to long-term care for older people who need it. In light of this situation, what can academics from universities in LAC do? If we organize ourselves and unite efforts, we can contribute to the Decade of Healthy Aging and, consequently, influence the quality of life of older people.

Efectos del ejercicio físico sobre la calidad de vida en personas mayores. Revisión de la literatura

RESUMEN El objetivo de esta revisión fue determinar cuál es la dosis óptima necesaria de ejercicio físico que debe realizar una persona mayor para generar efectos en la Calidad de Vida. Se realizó una búsqueda en bases de datos electrónicas entre 2015-2020. Como resultado, 9 de 33 artículos cumplieron con criterios de inclusión. La prescripción de ejercicio físico más utilizada en términos de FITT o FITT-VP fue: tipo, fuerza muscular a intensidad moderada a intensa, y/o ejercicio físico aeróbico a intensidad moderada; tiempo de sesión de 60 minutos; frecuencia 3 veces por semana; y tiempo de intervención mínimo 3 meses. En cuanto al volumen y progresión, la información fue limitada y justifica más estudios. Los efectos del ejercicio físico sobre la Calidad de Vida de las personas mayores se producirán cuando exista una programación basada como mínimo según FITT, se consideren los objetivos de la persona mayor, y la práctica sea regular.

ABSTRACT The objective of this review was to determine the optimal dose of physical exercise that an elderly person should perform to generate effects on Quality of Life. A search was carried out in electronic databases between 2015-2020. As a result, 9 of 33 articles met the inclusion criteria. The most used physical exercise prescription in terms of FITT or FITT-VP was: type, muscular strength at moderate to intense intensity, and / or aerobic physical exercise at moderate intensity; 60-minute session time; frequency 3 times a week; and intervention time at least 3 months. In terms of volume and progression, the information was limited and needs further studies. The effects of physical exercise on the Quality of Life of the elderly will occur when there is a schedule based at least according to FITT, the objectives of the elderly person are considered, and the practice is regular.

[Content validity of Food Quality Survey of Elderly (FQSE)]. / Validación de contenido de la Encuesta de Calidad de Alimentación del Adulto Mayor (ECAAM).

BACKGROUND: There are few instruments that evaluate the quality of food of elderly (ED) in the community. OBJECTIVE: To carry out the content validity of the survey designed to determine the Food Quality Survey of Elderly (FQSE). MATERIAL AND METHODS: Based on the existing literature, a questionnaire was designed to evaluate the FQSE. Content validity was performed using the Content Validity Index through the calculation of the Content Validity Ratio of Lawshe. Twenty-eight experts participated in the validation process. Subsequently, the validated survey was applied to ED. RESULTS: Twenty-three questions were validated in content, distributed in the 2 subscales of the instrument. The first 15 questions subscale Healthy eating habits and 8 questions subscale Unhealthy eating habits. The Content Validity Index was 0.85. Four hundred and fifty-eight ED were surveyed. In the subscale of Healthy eating habits, 11.2% of men and 11.4% of women presented healthy eating habits; 54.4% of men and 42.9% of women presented unhealthy eating habits. Finally, in the sum of both scales, only 16.6% of men and 17.6% of women categorize within Good Food Quality. CONCLUSION: The FQSE survey is a valid instrument in content and easy to apply to EL and allows evaluating and characterizing the quality of the diet of this age group.

Relación entre Apoyo Social percibido, Severidad de Insomnio y Somnolencia Diurna en Adultos Mayores / Relationship between perceived Social Support, Severity of Insomnia and Daytime Sleepiness in Elderly

El apoyo social es un importante factor protector de la salud de los adultos mayores (AM). Asimismo, un buen dormir es fundamental para su bienestar y funcionalidad, siendo las alteraciones del sueño un importante problema de salud pública en este grupo etario. El objetivo del estudio fue determinar la relación entre apoyo social percibido, insomnio y somnolencia diurna en AM residentes en Chillán, Chile. Se realizó un estudio cuantitativo, no experimental, correlacional, de corte transversal. Se aplicó la versión chilena de la Escala de Apoyo Social Percibido (MOS), el Índice de severidad del insomnio (ISI), y la Escala de somnolencia diurna de Epworth a AM pertenecientes a agrupaciones comunitarias. Se entrevistaron a 202 AM de ambos sexos, de edad 72,3±6,2 años. Se presentaron correlaciones positivas entre escolaridad y severidad del insomnio (p<0,05) y entre severidad del insomnio y somnolencia (p<0,001), además, se encontraron correlaciones negativas entre severidad del insomnio y apoyo social percibido, tanto en forma global como por dimensiones (p<0,05). La dimensión "Interacción social positiva" se correlacionó también de forma negativa con la somnolencia diurna. Los AM participantes del estudio que presentaron un alto nivel de apoyo social presentaron una menor prevalencia y severidad del insomnio

Social support is an important protective factor for the health of elderly (E).Likewise, good sleep is fundamental for their well-being and functionality, being sleep disorder an important public health problem in this age group. The objective of this study was to determine the relationship between perceived social support, insomnia and daytime sleepiness in elderly residents of Chillán, Chile. A quantitative, non-experimental, correlational, cross-sectional study was carried out. The Chilean version of the Perceived Social Support Scale (MOS), the Index of severity of insomnia (ISI) and the Daytime Sleepiness Scale of Epworth was applied to elderly belonging to community groups. Two hundred two elderly of both sexes were interviewed, age 72.3 ± 6.2 years. There were positive correlations between schooling and severity of insomnia (p <0.05) and between severity of insomnia and somnolence (p< 0.001). In addition, there were negative correlations between severity of insomnia and perceived social support, both globally and by dimensions (p <0.05). The dimension "Positive social interaction" also correlates negatively with daytime sleepiness. The elderly participants of the study who presented a high level of social support had a lower prevalence and severity of insomnia

Efectos del ejercicio físico sobre la calidad del sueño, insomnio y somnolencia diurna en personas mayores. Revisión de la literatura / Effects of physical exercise on sleep quality, insomnia, and daytime sleepiness in the elderly. A literature review

El transcurso del envejecimiento altera las etapas del sueño, y las personas mayores que consultan por este problema tienden a recibir tratamiento farmacológico, lo cual a largo plazo causa efectos secundarios y elevados costos en salud. En cambio, la práctica de ejercicio físico pudiese ser una alternativa, la cual tiene efectos multifactoriales, bajo costo y es accesible. Además estos beneficios podrían extrapolarse a la calidad del sueño. Por esto, el objetivo de esta revisión es determinar la dosificación de ejercicio físico a través del principio frecuencia, intensidad, tiempo y tipo de ejercicio y su efecto en la calidad de sueño, insomnio y somnolencia diurna en personas mayores. Esto generaría un cambio de paradigma en el tratamiento de los trastornos del sueño y ser una alternativa en el tratamiento de las personas mayores

Introducción: Con el creciente aumento de adulos mayores (AM) chilenos, se hace imperativo evaluar la calidad de la alimentación de este grupo etario, con instrumentos sencillos y rápidos. Objetivo: Comparar la calidad de la alimentación en AM de la comunidad, diferenciándolos por sexo y edad. Material y métodos: Estudio transversal en el que se entrevistaron 458 AM de 60 y más años de la ciudad de Santiago de Chile. A cada uno de ellos se les aplicó en su domicilio la Encuesta de Calidad de Alimentación del AM (ECAAM). El peso y estatura se obtuvo del carné de control del AM. Resultados: Los hombres consumen un mayor número de alimentos no saludables que las mujeres (p=0,01). Al comparar por edad, los AM ≥80 años son quienes consumen menos alimentos no saludables (p=0,01). Los AM obesos presentan el menor puntaje en hábitos alimentarios no saludables y consumo total (p<0,05). Conclusión: Las mujeres se alimentan más saludablemente que los hombres, y a mayor edad se puede observar una mejor calidad de alimentación, especialmente en hombres. Finalmente, al comparar según el estado nutricional, los AM obesos son quienes se alimentan de forma más inadecuada

Introduction: With the increase in the elderly population of Chile, it is very important to evaluate the quality of food of this age group using simple and quick tools. Objective: To compare the food quality of the elderly, according to gender and age. Material and methods: A cross sectional study was conducted on 458 elderly subjects ≥60 years-old of Santiago de Chile. Each one of them were interviewed in their home using the Food Quality Survey for Elderly (FQSE). The objective of this survey is to measure the quality of the food and preparations considered healthy and/or unhealthy for elderly. Weight and height, was obtained from the control document of the elderly. Results: Men consume a higher number of unhealthy foods compared to women (P=.01). On comparing ages, those over 80 years-old consumed less unhealthy foods (P=.01). The elderly obese showed a lower score in unhealthy eating habits and total intake score. Conclusion: Women eat healthier compared to men, and better eating habits are observed at an older age, especially in men. Finally, on comparing nutritional status, the elderly obese are those who eat in the most inadequate form
