The Role of Telemedicine in the Management of the Behavioral and Psychological Symptoms of Dementia: A Systematic Review.

The first-line management of behavioral and psychological symptoms of dementia (BPSD) is based on nonpharmacologic interventions such as the provision of guidance and medical support to caregivers. However, accessibility to specialized care and medical resources is often scarce. The ongoing COVID-19 pandemic has compromised the delivery of outpatient care (notably in order to minimize the risk of disease transmission), thus making it essential to provide other means of accessing care for these patient populations. The use of telemedicine (TM) may be a means of increasing access to specialist care for patients with disabilities and poor access to health services, such as those with BPSD. The aim of this study is to provide a review of the literature on the use of TM for treatment and follow-up of patients with BPSD and their caregivers. We searched the PUBMED, EMBASE and CINAHL for articles published between January 1st, 2000, and December 31st, 2020, on the applicability of TM support for people with BPSD and their caregivers. We included open-label studies, qualitative studies, and randomized controlled trials . We did not include studies on the use of TM during the COVID-19 pandemic. A total of 22 publications were included and reviewed. TM was found to 1) be acceptable and feasible for both patients and caregivers, 2) decrease the frequency and intensity of BPSD, and 3) improve the caregiver's perceived wellbeing and mental health. Videoconferencing was effective for patient-centered interventions in nursing homes. Telephone-based interventions were more relevant when they were targeted at caregivers. The published studies are lacking in scope and high-quality studies are now needed to confirm these findings and assess TM's cost-effectiveness and ability to improve the management of patients with BPSD. In view of the ongoing COVID-19 pandemic, remote solutions for assessing and monitoring individuals with BPSD are urgently needed - particularly those living in rural areas and so-called "medical deserts."

Cluster randomized trials in nursing homes should better be planned as open-cohort than as closed-cohort.

OBJECTIVES: Two designs are frequently used in cluster randomized trials in nursing homes: closed cohort and open cohort. The former design includes residents at the beginning of the trial and then follows them. In the latter design, participants are enrolled at the beginning of the trial or although it is ongoing; at dates of assessment, all residents present in the nursing home are assessed. The open-cohort design is much less used than the closed-cohort design, but it offers several advantages such as less exposure to individual attrition. Objective was to assess whether an open-cohort design could have been feasible in trials with a closed-cohort design. STUDY DESIGN AND SETTING: Twenty-two closed-cohort trials in nursing homes. RESULTS: An open-cohort design was considered a relevant alternative for 20 trials. For 16 trials, a resident newly admitted could not opt out of the intervention, and for all trials, the resident could benefit from an intervention effect if it existed. For two trials, newly admitted residents could not benefit from the intervention effect, if it existed. CONCLUSION: The open-cohort design is well-adapted for most of the interventions assessed in nursing homes by means of a cluster randomized trial and should be considered more often.

High Prevalence of Geriatric Conditions Among Older Adults With Cardiovascular Disease.

As the population ages, the global cardiovascular disease burden will continue to increase, particularly among older adults. Increases in life expectancy and better cardiovascular care have significantly reshaped the epidemiology of cardiovascular disease and have created new patient profiles. The combination of older age, multiple comorbidities, polypharmacy, frailty, and adverse noncardiovascular outcomes is challenging our routine clinical practice in this field. In this review, we examine noncardiovascular factors that statistically interact in a relevant way with health status and quality of life in older people with cardiovascular disease. We focused on specific geriatric conditions (multimorbidity, polypharmacy, geriatric syndromes, and frailty) that are responsible for a major risk of functional decline and have an important impact on the overall prognosis in this patient population.

Digital health technologies and Alzheimer's disease clinical trials: might decentralized clinical trials increase participation by people with cognitive impairment?

BACKGROUND: Therapeutic trials in Alzheimer's disease (AD) face many obstacles-particularly with regard to screening and recruitment. DISCUSSION: Decentralized clinical trials (DCTs) are being developed in other diseases and appear to be of value for overcoming these difficulties. The use of remote visits offers hope of broader recruitment and thus a reduction in inequalities due to age, geography, and ethnicity. Furthermore, it might be easier to involve primary care providers and caregivers in DCTs. However, further studies are needed to determine the feasibility of DCTs in AD. A mixed-model DCT might constitute the first step towards completely remote trials in AD and should be assessed first.

Associations Between Frailty and Inflammation, Physical, and Psycho-Social Health in Older Adults: A Systematic Review.

Frailty is a complex geriatric syndrome with multifactorial associated mechanisms that need to be examined more deeply to help reverse the adverse health-related outcomes. Specific inflammatory and physical health markers have been associated with the onset of frailty, but the associations between these factors and psycho-social health outcomes seem less studied. This systematic review aimed to identify, in the same study design, the potential associations between frailty and markers of inflammation, and physical or psycho-social health. A literature search was performed from inception until March 2021 using Medline, Psycinfo, and EMBASE. Three raters evaluated the articles and selected 22 studies, using inclusion and exclusion criteria (n = 17,373; 91.6% from community-dwelling samples). Regarding biomarkers, 95% of the included studies showed significant links between inflammation [especially the higher levels of C-reactive protein (CRP) and interleukin-6 (IL-6)], and frailty status. Approximately 86% of the included studies showed strong links between physical health decline (such as lower levels of hemoglobin, presence of comorbidities, or lower physical performance), and frailty status. At most, 13 studies among the 22 included ones evaluated psycho-social variables and mixed results were observed regarding the relationships with frailty. Results are discussed in terms of questioning the medical perception of global health, centering mostly on the physical dimension. Therefore, the development of future research studies involving a more exhaustive view of frailty and global (bio-psycho-social) health is strongly encouraged.

Analysis of the Impact of Selected Vitamins Deficiencies on the Risk of Disability in Older People.

Vitamin deficiencies have a serious impact on healthy aging in older people. Many age-related disorders have a direct or indirect impact on nutrition, both in terms of nutrient assimilation and food access, which may result in vitamin deficiencies and may lead to or worsen disabilities. Frailty is characterized by reduced functional abilities, with a key role of malnutrition in its pathogenesis. Aging is associated with various changes in body composition that lead to sarcopenia. Frailty, aging, and sarcopenia all favor malnutrition, and poor nutritional status is a major cause of geriatric morbidity and mortality. In the present narrative review, we focused on vitamins with a significant risk of deficiency in high-income countries: D, C, and B (B6/B9/B12). We also focused on vitamin E as the main lipophilic antioxidant, synergistic to vitamin C. We first discuss the role and needs of these vitamins, the prevalence of deficiencies, and their causes and consequences. We then look at how these vitamins are involved in the biological pathways associated with sarcopenia and frailty. Lastly, we discuss the critical early diagnosis and management of these deficiencies and summarize potential ways of screening malnutrition. A focused nutritional approach might improve the diagnosis of nutritional deficiencies and the initiation of appropriate clinical interventions for reducing the risk of frailty. Further comprehensive research programs on nutritional interventions are needed, with a view to lowering deficiencies in older people and thus decreasing the risk of frailty and sarcopenia.
