RESUMEN
COVID-19 led to unprecedented lockdowns and changes in older adults' lives, especially those with type 2 diabetes who have high risk of complications and mortality. We investigated the associations of cognitive and motor function and gray matter volumes (GMVs) with COVID-19 lockdown-related emotional distress of type 2 diabetes older adults, participating in the Israel Diabetes and Cognitive Decline Study. We administered a questionnaire to obtain information about anxiety, depression, general well-being, and optimism during a mandated lockdown. Lower grip strength before lockdown was associated with increased sadness, anxiety, and less optimism. Slower gait speed was associated with greater sadness. Lower GMV was related to greater anxiety during the lockdown when compared with anxiety levels before the COVID-19 outbreak. Yet, global cognition was not associated with any emotional distress measure. These results support the role of good motor function on emotional well-being during acute stress and GMV as a potential underlying mechanism.

Background: Improving the mobility of hospitalized patients with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a priority of care. AECOPD-Mob is a clinical decision-making tool for physical therapists, especially those who are newly graduated or are new to caring for patients with AECOPDs in acute care settings. Although this tool has been available for several years, dissemination via publication is not sufficient to implement it in clinical practice.Objective: The primary objective of this study was to develop, implement, and evaluate different formats of AECOPD-Mob in an acute care setting.Methods: We used a mixed-methods, convergent parallel design. In addition to the paper format of AECOPD-Mob, we developed a smartphone app, a web-based learner module, and an in-service learning session. Newly graduated physical therapists (PTs) or PTs new to the practice area were recruited from urban acute care hospitals. Participants used the different formats for 3 weeks and then completed the Post-Study System Usability Questionnaire. User data were retrieved for the learning module. Participants participated in focus groups at 3 weeks and 3 months.Results: Eighteen (72% of eligible PTs, 100% female, 94% graduated within 3 yr) PTs participated. Post-Study System Usability Questionnaire scores for the learning module and smartphone indicated that participants were satisfied with these formats (median score 2.0 on 1-7 Likert Scale for both technology formats, lower scores indicating greater satisfaction). However, the participants reported in the focus group that the paper format was preferred over other formats. Concerns with the smartphone app included infection control and the perception of lack of professionalism when using a smartphone during clinical practice. The learning module and in-service were considered helpful as an introduction but not as an ongoing support. The paper format was seen as the most efficient way to access the necessary information and to facilitate communication between other members of the care team about the importance of mobility for hospitalized patients with AECOPDs.Conclusion: Newly graduated PTs strongly preferred the paper format of the AECOPD-Mob tool in the acute care setting. Future research will focus on knowledge translation strategies for other health disciplines.
RESUMEN
INTRODUCTION: Type 2 diabetes (T2D) is a risk factor for dementia. Ischemia due to vascular pathology is hypothesized to be an underlying mechanism for this association. Hyperbaric oxygen therapy (HBOT) is a treatment in which oxygen-enriched air (up to 100%) is administered to patients in a chamber at a pressure above one atmosphere absolute. HBOT is approved for the treatment of T2D ischemic non-healing wounds. Evidence from animal studies and small clinical trials suggests that HBOT improves hypoxic/ischemic brain injuries, consequently inducing brain angiogensis, leading to cognitive improvement. METHODS: We present the design of the first double-blind, placebo-controlled, clinical trial on brain and cognitive outcomes in elderly (n = 154) with T2D and mild cognitive impairment to compare the effects of HBOT versus sham (normal air with 1.1 ATA pressure in the first and last 5 minutes of the session). Eligible candidates are randomized with equal probability to HBOT and sham. Outcomes are assessed before and after treatment, and at 6- and 12-month follow-up. The primary cognitive outcome is global cognitive change, indexed by a composite sum of z-scores of four executive functions and four episodic memory tests. The primary neurobiological outcome is cerebral blood flow (CBF; via arterial spin labeling magnetic resonance imaging [ASL-MRI]) and cerebral glucose utilization via fluorodeoxyglucose positron emission tomography (FDG-PET). Secondary outcome measures are specific cognitive domains (executive function and episodic memory) and functional measures (Clinical Dementia Rating sum of boxes, activities of daily living). Efficacy analyses will be performed for the intent-to-treat sample. DISCUSSION: Recent studies suggest that HBOT induces neuroplasticity and improves cognition in post-stroke and traumatic brain injury patients. However, its effect on cognition, cerebral blood flow, and brain glucose utilization in T2D patients at high dementia risk is yet to be determined. If effective, this study may provide strong evidence for the brain and cognitive benefits of HBOT in this population.
