ABSTRACT
BACKGROUND: Migration is a phenomenon worldwide, with older migrants, particularly those with fewer socioeconomic resources, having an increased risk of developing adverse cognitive and health outcomes and social isolation. Therefore, it is of utmost importance to validate interventions that promote healthy aging in this population. Previous studies have shown a positive impact of mindfulness based-stress reduction (MBSR) on outcomes such as cognition and sleep. However, only a few studies verified its potential in older adults, especially with vulnerable populations such as migrants. This article presents the protocol of the MEDITAGING study, which is the first to investigate the MBSR effects in migrants aged ≥55 in comparison to a health promotion program. METHODS: MEDITAGING is a two-arm randomized, double-blinded, controlled study, which will include older Portuguese-speaking migrants (n = 90). Participants are randomized to the MBSR or a health promotion program. Both interventions are conducted in groups over a total of 8 weeks, incorporating weekly meetings, an additional 4-hour class, and extra at-home tasks. The health promotion program has the same structure as the MBSR but comprises different activities related to dementia prevention, healthy habits, cognitive stimulation, sleeping, nutrition, watercolor painting, and physical activity. The assessment of executive functioning, physiological stress measures, self-reported questionnaires, and qualitative interviews are conducted at baseline, after 8 weeks (post-intervention), and at a follow-up session (from one to 3 months thereafter). Analyzes will be conducted using a modified intention-to-treat approach (all participants with at least 3 days of participation in the group-sessions and one post-intervention observation). DISCUSSION: This study will test effects of a mindfulness-based intervention against an active control condition in older adult migrants, which few studies have addressed. TRIAL REGISTRATION: ClinicalTrials.gov NCT05615337 (date of registration: 27 September 2022; date of record verification: 14 November 2022).

BACKGROUND: Side-stepping is a potential exercise program to reduce fall risk in community-dwelling adults in their seventies, but it has never been tested in nursing home residents. This was a pilot quasi-experimental study to examine the feasibility and potential mobility and balance benefits of an intervention based on voluntary non-targeted side-stepping exercises in nursing home residents who fall recurrently. METHODS: Twenty-two participants were recruited and non-randomly assigned to an intervention group ([Formula: see text]11, side-stepping exercises, STEP) participating in an 8-week protocol and to a control group ([Formula: see text]11, usual physiotherapy care, CTRL). They were clinically assessed at 4-time points: baseline, after 4 and 8 weeks, and after a 4-week follow-up period (usual physiotherapy care). Statistical differences between time points were assessed with a Friedman repeated measures ANOVA on ranks or a one-way repeated measures ANOVA. RESULTS: Compared to baseline, significant benefits were observed in the STEP group at 8 weeks for the Timed Up and Go ([Formula: see text]0.020) and 6-minute walking test ([Formula: see text]0.001) as well as for the Berg Balance Scale ([Formula: see text]0.041) and Mini motor test ([Formula: see text]0.026). At follow-up, the Tinetti Performance Oriented Mobility Assessment and Berg Balance Scale significantly worsened in the STEP group ([Formula: see text]0.009 and [Formula: see text]0.001, respectively). No significant differences were found between the groups at the same time points. CONCLUSIONS: Our intervention was feasible and improved mobility and balance after almost 8 weeks. Studies with larger samples and randomized control trials are needed to consolidate our preliminary observations and confirm the deterioration of some tests when side-stepping exercises are discontinued.

INTRODUCTION: The use of social marketing strategies to induce the promotion of cognitive health has received little attention in research. The objective of this scoping review is twofold: (i) to identify the social marketing strategies that have been used in recent years to initiate and maintain health-promoting behaviour; (ii) to advance research in this area to inform policy and practice on how to best make use of these strategies to promote cognitive health. METHODS AND ANALYSIS: We will use the five-stage methodological framework of Arksey and O'Malley. Articles in English published since 2010 will be searched in electronic databases (the Cochrane Library, DoPHER, the International Bibliography of the Social Sciences, PsycInfo, PubMed, ScienceDirect, Scopus). Quantitative and qualitative study designs as well as reviews will be considered. We will include those articles that report the design, implementation, outcomes and evaluation of programmes and interventions concerning social marketing and/or health promotion and/or promotion of cognitive health. Grey literature will not be searched. Two independent reviewers will assess in detail the abstracts and full text of selected citations against the inclusion criteria. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses flowchart for Scoping Reviews will be used to illustrate the process of article selection. We will use a data extraction form, present the results through narrative synthesis and discuss them in relation to the scoping review research questions. ETHICS AND DISSEMINATION: Ethics approval is not required for conducting this scoping review. The results of the review will be the first step to advance a conceptual framework, which contributes to the development of interventions targeting the promotion of cognitive health. The results will be published in a peer-reviewed scientific journal. They will also be disseminated to key stakeholders in the field of the promotion of cognitive health.

The reliable measurement of quality of life (QoL) presents a challenge in individuals with alcohol-related brain damage. This study investigated vagally mediated heart rate variability (vmHRV) as a physiological predictor of QoL. Self- and proxy ratings of QoL and dysexecutive symptoms were collected once, while vmHRV was repeatedly assessed over a 3-week period at weekly intervals in a sample of nine alcohol-related brain damaged patients. We provide robustness checks, bootstrapped correlations with confidence intervals, and standard errors for mean scores. We observed low to very low heart rate variability scores in our patients in comparison to norm values found in healthy populations. Proxy ratings of the QoL scale "subjective physical and mental performance" and everyday executive dysfunctions were strongly related to vmHRV. Better proxy-rated QoL and fewer dysexecutive symptoms were observed in those patients with higher vmHRV. Overall, patients showed low parasympathetic activation favoring the occurrence of dysfunctional emotion regulation strategies.
ABSTRACT
BACKGROUND: The interrelationship between gait performance and higher-order cognitive functions has been established through a number of different investigations. In turn, enabling gait by improving cognition is a new and emerging field of research. AIMS: Investigating if and to what extent a structured cognitive training program influences gait-related parameters in a sample of old and frail nursing home residents. METHODS: Twenty-one nursing home residents were quasi-randomized to an intervention group following a 6-week structured cognitive training program or a control group. Gait was investigated during normal pace and under two dual-task conditions (simple and complex dual-task walking conditions), using the GAITRite(®) system at three predefined time points (pre-intervention, post-intervention, 3-month follow-up). Outcome measures were gait speed and stride variabilities. RESULTS: Confirmation of the interrelationship between gait and cognition evidenced by decreased gait parameters during complex dual-task walking. Observation of clinical meaningful improvements in gait stability and gait speed after the training program under the complex dual-task situations, with only speed remaining stable over a period of 3 months. DISCUSSION: This study on the effects of cognitive training on gait is promising, with several results going in the expected direction. Our data corroborate previous findings and extend them to the group of frail old nursing home residents. CONCLUSIONS: The present pilot study's approach of improving gait under challenging walking situations by interventions designed to improve cognitions adds encouraging results to this emerging field of research, although restrictions in sample size and in the control group prevent us from drawing firm conclusions.
