RESUMO

Introducción El creciente envejecimiento poblacional trae consigo un aumento de la incidencia del trastorno neurocognitivo (TNC) así como diversas situaciones generadoras de dependencia. Objetivo Analizar mediante una revisión sistemática la relación que existe entre TNC y dependencia con el riesgo de mortalidad en personas mayores. Métodos Se realizó una búsqueda bibliográfica de los estudios longitudinales publicados en Pubmed y Scopus abordando la relación entre TNC, dependencia para las actividades básicas de la vida diaria (ABVD) y mortalidad publicados entre los años 1995 y 2021 De los 1040 artículos encontrados, se seleccionaron 10 estudios. Resultados Se observó que las cohortes de personas mayores con TNC presentaron riesgo de mortalidad asociado a la afectación de las ABVD (test de Barthel) y a las puntuaciones de Mini-Mental State Examination siguiendo una tendencia lineal significativa. Otros factores asociados al riesgo de mortalidad fueron: niveles bajos de educación, vivir solo y presentar fragilidad. Es clara la vinculación entre los tres términos utilizados en la búsqueda de este trabajo y, sin embargo, destaca que haya pocos estudios longitudinales que los analicen conjuntamente. Conclusiones Los resultados hallados subrayan la importancia de realizar evaluaciones del estado cognitivo y funcional mediante escalas validadas, ya que ambas áreas se asocian con la mortalidad. La evaluación de la dependencia y de la función cognitiva en adultos mayores debe considerarse tanto en la investigación como en la práctica clínica, ya que aportarían información sobre su posible relación con la mortalidad.

Introduction The increasing aging of the population brings with it an increase in the incidence of neurocognitive disorder (NCD) as well as various situations that generate dependence. Objective To analyze by means of a systematic review the relationship between NCD and dependence with the risk of mortality in the elderly. Methods A bibliographic search of longitudinal studies published in Pubmed and Scopus addressing the relationship between NCI, dependence for basic activities of daily living (ADL) and mortality published between 1995 and 2021 was performed. Of the 1040 articles found, 10 studies were selected. Results It was observed that cohorts of elderly people with NCI presented mortality risk associated with ABVD impairment (Barthel test) and Mini-Mental State Examination scores following a significant linear trend. Other factors associated with mortality risk were low levels of education, living alone, and frailty. Conclusions The results underline the importance of performing assessments of cognitive and functional status using validated scales, since both areas are associated with mortality. The link between the three terms used in the search for this work is clear, but it is noteworthy that there are few longitudinal studies that analyze them together. The assessment of dependence and cognitive function in older adults should be considered in both research and clinical practice as it would provide information on their possible relationship with mortality.

RESUMO

People living with dementia (PLWD) and their family caregivers report higher rates of having a sedentary lifestyle than their non-disabled peers do. This study analyzed the effectiveness of an intervention designed to increase physical activity among PLWD and their family caregivers in primary health care settings. A cluster-randomized multicenter clinical trial was conducted. Participants from four health centers were randomly assigned to the intervention group (IG) or the control group (CG) in a 1:1 ratio using Epidat software. After a seven-day period with a digital pedometer (Omron Hj-321 lay-UPS), participants were asked to complete the International Physical Activity Questionnaire Short Form (IPAQ-SF). PLWD and caregivers allocated to the IG were given brief advice, educational materials and an additional 15 min appointment to prescribe an individualized physical activity plan. Seventy PLWD and 80 caregivers were assigned to the CG and 70 PLWD and 96 caregivers were assigned to the IG. Results of the pedometer assessment show that in PLWD, the IG's activity increased by 52.89 aerobic steps at 6 months and the CG's activity decreased by 615.93 aerobic steps, showing a net increase in the IG of 668.82 (95% CI: -444.27 to 1781.91; p = 0.227). For caregivers in the IG, activity increased by 356.91 aerobic steps and in the CG it decreased by 12.95 aerobic steps, showing a net increase in favor of the IG of 369.86 (95%CI: -659.33 to 1399.05; p = 0.476). The effectiveness of interventions to increase physical activity in this group of people with dementia and their caregivers did not achieved positive results overall but may have provided suggestions for family physicians and physical therapists to improve physical activity among people with dementia and their families.

RESUMO

To maximize the driving range and minimize the associated energy needs and, thus, the number of batteries of electric vehicles, OEMs have adopted lightweight materials, such as long fiber-reinforced thermoplastics, and new processes, such as microcellular injection molding. These components must withstand specific loading conditions that occur during normal operation. Their mechanical response depends on the fiber and foam microstructures, which in turn are defined by the fabrication process. In this work, long fiber thermoplastic door panels were manufactured using the Ku-FizzTM microcellular injection molding process and were tested for their impact resistance, dynamic properties, and vibration response. Material constants were compared to the properties of unfoamed door panels. The changes in mechanical behavior were explained through the underlying differences in their respective microstructures. The specific storage modulus and specific elastic modulus of foamed components were within 10% of their unfoamed counterparts, while specific absorbed energy was 33% higher for the foamed panel by maintaining the panel's mass/weight.

RESUMO

Coal-to-gas switching in the power sector, as happening in the U.S., has been a key driver of near-term greenhouse gas emissions reductions. Can this success be replicated around the world? Here, we explore the limits of a global, plant-level, coal-to-gas transition arising from pipeline availability constraints. Globally, only 43% of coal capacity is within 14 km of a nearby pipeline, the median distance for recent coal-to-gas conversions. Furthermore, plant-to-pipeline distance distributions vary widely-only 30% of coal capacity in India is within 14 km of a nearby pipeline. Most global coal fleets are in the intermediate space of balancing two competing interests-having a young coal fleet with high "avoided" emissions potential through coal-to-gas switching but without access to low-cost gas resources. A global stocktake based on coal fleet age, pipeline access, and natural gas supply security suggests that a coal-to-gas transition in the power sector is unlikely to be a universal climate solution.

RESUMO

We present near-field radio holography measurements of the Simons Observatory Large Aperture Telescope Receiver optics. These measurements demonstrate that radio holography of complex millimeter-wave optical systems comprising cryogenic lenses, filters, and feed horns can provide detailed characterization of wave propagation before deployment. We used the measured amplitude and phase, at 4 K, of the receiver near-field beam pattern to predict two key performance parameters: 1) the amount of scattered light that will spill past the telescope to 300 K and 2) the beam pattern expected from the receiver when fielded on the telescope. These cryogenic measurements informed the removal of a filter, which led to improved optical efficiency and reduced sidelobes at the exit of the receiver. Holography measurements of this system suggest that the spilled power past the telescope mirrors will be less than 1%, and the main beam with its near sidelobes are consistent with the nominal telescope design. This is the first time such parameters have been confirmed in the lab prior to deployment of a new receiver. This approach is broadly applicable to millimeter and submillimeter instruments.

RESUMO

OBJECTIVES: The aim of this research was to evaluate the effects of adding 10 g of cocoa-rich chocolate (99%) to the habitual diet on cognitive performance in postmenopausal women. METHODS: Following a randomised controlled parallel clinical trial, a total of 140 postmenopausal women aged 50-64 were recruited. The intervention group (n = 73) consumed daily 10 g of chocolate (99% cocoa) in addition to their usual food intake for 6 months, whereas the control group (n = 67) did not receive any intervention. Attention and executive functions, verbal memory, working memory, phonological fluency, category fluency and clinical variables were assessed at baseline and 6 months. RESULTS: Trail Making Test B execution time showed a decreased of -12.08 s (95% CI: -23.99, -0.18; p = 0.047) in the intervention group compared to the control group, after adjusting for age, educational level, time elapsed from the beginning of menopause and daily energy consumption (Cohen's d = -0.343). Attention, immediate or delayed verbal memory, phonological or category fluency, and working memory remained unchanged. CONCLUSIONS: The consumption of cocoa-rich (99%) chocolate in addition to the habitual diet could be related to a slight improvement in cognitive performance regarding cognitive flexibility and processing speed in postmenopausal women, with no changes in the rest of the cognitive performance variables evaluated.Trial registration: This clinical trial has been registered at clinicaltrials.gov as NCT03492983.

RESUMO

Near-field radio holography is a common method for measuring and aligning mirror surfaces for millimeter and sub-millimeter telescopes. In instruments with more than a single mirror, degeneracies arise in the holography measurement, requiring multiple measurements and new fitting methods. We present HoloSim-ML, a Python code for beam simulation and analysis of radio holography data from complex optical systems. This code uses machine learning to efficiently determine the position of hundreds of mirror adjusters on multiple mirrors with few micrometer accuracy. We apply this approach to the example of the Simons Observatory 6 m telescope.

RESUMO

We present geometrical and physical optics simulation results for the Simons Observatory Large Aperture Telescope. This work was developed as part of the general design process for the telescope, allowing us to evaluate the impact of various design choices on performance metrics and potential systematic effects. The primary goal of the simulations was to evaluate the final design of the reflectors and the cold optics that are now being built. We describe nonsequential ray tracing used to inform the design of the cold optics, including absorbers internal to each optics tube. We discuss ray tracing simulations of the telescope structure that allow us to determine geometries that minimize detector loading and mitigate spurious near-field effects that have not been resolved by the internal baffling. We also describe physical optics simulations, performed over a range of frequencies and field locations, that produce estimates of monochromatic far-field beam patterns, which in turn are used to gauge general optical performance. Finally, we describe simulations that shed light on beam sidelobes from panel gap diffraction.

RESUMO

African Americans in Mississippi have the highest HIV-related mortality and poverty rates in the USA, and they tend to be religious. Attitudes toward gender and sexuality are changing, yet few studies have investigated religion and spirituality among special populations living with HIV. Using grounded theory and qualitative methods, we investigated the experience of health and illness of a low-income, socially marginalised population living with HIV in two locations of Mississippi in 2015. In a context of high stigma and HIV-related health disparities, individuals turned, or returned, to religion, church and spirituality as sources of community and strength, which also motivated safer health behaviours. Findings underscore how religion and spirituality are enabling social determinants of health that are under-explored, untapped, potentially culturally acceptable, sustainable interventions at the community-level. We posit, given diminished funding for community-based services, the most significant influence churches could exert is in decreasing HIV stigma. Given the current US plan to end HIV by 2030, with appropriate stakeholder participation, the role of religion, spirituality and clergy could be further amplified via linkage to care providers and the 'normalisation' of the HIV discourse, to address disparities and improve the health of African Americans.

RESUMO

AIM: This study assesses the effect of an intervention to reduce the disruptive behaviours (DB) presented by care recipient users of adult day care centres (ADCC), thereby reducing caregiver overload. While ADCC offer beneficial respite for family caregivers, the DB that many care recipients show promote resistance to attending these centres, which can be a great burden on their family caregivers. DESIGN: Randomized controlled clinical trial. METHODS: The study was carried out with 130 family caregivers of people attending seven ADCC in the municipality of Salamanca (Spain), randomly distributed into intervention and control groups. The intervention was applied across eight sessions, one per week, in groups of 8-10 people where caregivers were trained in the Antecedent-Behavior-Consequence (ABC) model of functional behaviour analysis. The primary outcome was the reduction of DB measured with the Revised Memory and Behavior Problems Checklist (RMBPC). RESULTS: An average reduction in the RMBPC of 4.34 points was obtained in the intervention group after applying the intervention (p < 0.01 (U de Mann-Whitney); Cohen d = 1.00); furthermore, differences were found in the Center for Epidemiologic Studies Depression Scale (CES-D) (U = -2.67; p = 0.008; Cohen d = 0.50) and in the Short Zarit Burden Interview (Short ZBI) (t = -4.10; p < 0.01; Cohen d = 0.98). CONCLUSION: The results obtained suggest that the implementation of this intervention could reduce both the frequency of DB occurrence and the reaction of the caregiver to their appearance. Improvement was also noted in the results regarding overload and emotional state of the family caregiver. IMPACT: To our knowledge, this is the first randomized clinical trial to show that an intervention based on the ABC model could reduce the frequency and reaction of DB of care recipients in ADCC increasing their quality of life, and improving the mental health and overload of their family caregivers.

RESUMO

The disproportionate burden of HIV-related inequities borne by African Americans in the US South amplifies the role of social determinants of health (SDH) in shaping social patterning of illness. Despite some attention, SDH remain overlooked in a biomedically oriented, federal HIV policy. Mississippi is the poorest state with the worst HIV outcomes, nationally. Using qualitative methods, we investigated how primarily African American, HIV-positive Mississippians experienced SDH and health inequities in their daily lives. Employing grounded theory and in-depth interviews (n = 25) in an urban and rural site in 2015 yielded these findings: (1) absence of an enabling structural environment; (a) HIV-stigma constructed via social discourse; (b) lack of psycho-social support and HIV education; (c) insufficient economic and social support resources; and (2) presence of family support for coping. Due to stigma, being HIV-positive seemed to lead to further status loss; diminished social position; reduced life chances; and contractions in particular freedoms. Stigma further compounded existing inequalities - contributing to the moral, social experience of those living with HIV. Trump's plan to end HIV by 2030 creates the opportunity to rethink the biomedical-paradigm and fully engage SDH - using social science theory and methods that address multi-level social determinants in ways that are also policy-responsive.

RESUMO

Objective: To evaluate the postprandial effects of high and low glycaemic index (GI) breakfasts on cognitive performance in young, healthy adults.Methods: A crossover clinical trial including 40 young, healthy adults (aged 20-40 years, 50% females) recruited from primary healthcare centres in Salamanca, Spain. Verbal memory, phonological fluency, attention, and executive functions were examined 0, 60, and 120 minutes after consuming a low GI (LGI), high GI (HGI), or water breakfast. Every subject tried each breakfast variant, in a randomized order, separated by a washout period of 7 days, for a total of 3 weeks.Results: A significant interaction between the type of breakfast consumed and immediate verbal memory was identified (P<.05). We observed a trend towards better performance in verbal memory (delayed and immediate), attention, and phonological fluency following an LGI breakfast.Discussion: Cognitive performance during the postprandial phase in young, healthy adults was minimally affected by the GI of breakfast. The potential for breakfast's GI modulation to improve short- and long-term cognitive functioning requires further research.

RESUMO

BACKGROUND: The increasing use of smartphones by older adults also increases their potential for improving different aspects of health in this population. Some studies have shown promising results in the improvement of cognitive performance through lifestyle modification. All this may have a broad impact on the quality of life and carrying out daily living activities. The objective of this study is to evaluate the effectiveness of combining the use of smartphone and smartband technology for 3 months with brief counseling on life habits, as opposed to providing counseling only, in increasing physical activity and improving adherence to the Mediterranean diet. Secondary objectives are to assess the effect of the intervention on body composition, quality of life, independence in daily living activities and cognitive performance. METHODS: This study is a two-arm cluster-randomized trial that will be carried out in urban health centers in Spain. We will recruit 160 people aged between 65 and 80 without cardiovascular disease or cognitive impairment (score in the Mini-mental State Examination ≥24). On a visit to their center, intervention group participants will be instructed to use a smartphone application for a period of 3 months. This application integrates information on physical activity received from a fitness bracelet and self-reported information on the patient's daily nutritional composition. The primary outcome will be the change in the number of steps measured by accelerometer. Secondary variables will be adherence to the Mediterranean diet, sitting time, body composition, quality of life, independence in daily living activities and cognitive performance. All variables will be measured at baseline and on the assessment visit after 3 months. A telephone follow-up will be carried out at 6 months to collect self-reported data regarding physical activity and adherence to the Mediterranean diet. DISCUSSION: Preventive healthy aging programs should include health education with training in nutrition and lifestyles, while stressing the importance of and enhancing physical activity; the inclusion of new technologies can facilitate these goals. The EVIDENT-AGE study will incorporate a simple, accessible intervention with potential implementation in the care of older adults. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03574480 . Date of trial Registration July 2, 2018.

RESUMO

INTRODUCTION: The intake of polyphenols has certain health benefits. This study will aim to assess the effect of adding a daily amount of chocolate high in cocoa content and polyphenols to the normal diet on blood pressure, vascular function, cognitive performance, quality of life and body composition in postmenopausal women. METHODS AND ANALYSIS: Here we plan a randomised clinical trial with two parallel groups involving a total of 140 women between 50 and 64 years in the postmenopausal period, defined by amenorrhoea of ​​at least 12 consecutive months. The main variable will be the change in blood pressure. Secondary variables will be changes in vascular function, quality of life, cognitive performance and body composition. The intervention group will be given chocolate containing 99% cocoa, with instructions to add 10 g daily to their normal diet for 6 months. The daily nutritional contribution of this amount of chocolate is 59 kcal and 65.4 mg of polyphenols. There will be no intervention in the control group. All variables will be measured at the baseline visit and 3 and 6 months after randomisation, except cognitive performance and quality of life, which will only be assessed at baseline and at 6 months. Recruitment is scheduled to begin on 1 June 2018, and the study will continue until 31 May 2019. ETHICS AND DISSEMINATION: This study was approved by the Clinical Research Ethics Committee of the Health Area of Salamanca, Spain ('CREC of Health Area of Salamanca'), in February 2018. A SPIRIT checklist is available for this protocol. The clinical trial has been registered at ClinicalTrials.gov provided by the US National Library of Medicine, number NCT03492983. The results will be disseminated through open access peer-reviewed journals, conference presentations, broadcast media and a presentation to stakeholders.

RESUMO

AIM: This study evaluates the effectiveness of a behavioural intervention programme aimed at reducing the reluctance of dependent people to attend Adult Day Care Centres. We hope that reducing resistance will have a positive influence on the mental health of caregivers. BACKGROUND: Care centres offer important relief and rest services for family caregivers. Some caregivers report being affected by behavioural and psychological symptoms of dementia when they prepare dependents for the Care Centres, especially when these have dementia. Caregivers often report the need for information about how to manage the behaviour of the sick. Nurses in community healthcare units can investigate cases of patients who present resistance when attending care centres and can promote the use of interventions aimed at reducing this problem. DESIGN: Randomised controlled clinical trial. METHODS: The reference population will be care centre users in Salamanca (Spain) to select 120 family members responsible for the preparation and transfer of the care-recipient. Each participant will be randomised to an intervention group or control group (standard care). A baseline assessment and 6 months follow-up assessment will be performed (study approved in September 2016). INTERVENTION: The intervention group will consist of 8 sessions, one per week, each lasting 90 min. Each session will be run by a psychologist trained in behaviour analysis and will be tailored to the specific behavioural problems reported by the caregivers. DISCUSSION: The results of a previously published pilot study allow us to be optimistic about the possibilities of a brief intervention.

RESUMO

AIM: The aim of this study was to evaluate the effectiveness of an intensive intervention led by primary care nurses for lifestyle modification among people with intermediate cardiovascular risk. BACKGROUND: Cardiovascular diseases may be prevented by adopting healthy lifestyles. Interventions focused on populations at risk are more efficient than those aimed at the general population. More than 50 per cent of cardiovascular events occur in people with intermediate cardiovascular risk, but only a few studies have targeted this population. DESIGN: A randomized controlled trial approved in January 2017. METHODS: We will recruit 208 participants aged 35-74 years who have intermediate cardiovascular risk. They will be selected by consecutive sampling and will be randomized into a control group or intervention group. Individual standardized brief counselling on healthy lifestyles will be provided to both groups. Additionally, individuals from the intervention group will receive four weekly group sessions focusing on cardiovascular risk, healthy diet, moderation in alcohol consumption, daily physical activity, stress management and smoking cessation and two motivational follow-up calls. The primary outcome will be the lifestyle modification measured by total steps recorded by a pedometer, total score on the Mediterranean Diet Adherence Screener and percentage of current smokers. DISCUSSION: This study will allow us to investigate whether an intensive intervention based on a multifactorial group approach is more effective in lifestyle modification than individual standardized brief counseling among adults with intermediate cardiovascular risk.
