Background: The benefits of physical activity (PA), specifically exercise, among older adults in general are well known. Yet globally, there is concern regarding limited engagement in PA, increased obesity, and frailty among older people with human immunodeficiency virus related to low levels of PA.

Methods: We conducted in-depth interviews among 30 older, sedentary people with human immunodeficiency virus participating in the ongoing High-Intensity Exercise to Attenuate Limitations and Train Habits (HEALTH study, NCT04550676) between February 2021 and August 2022. A semistructured interview guide, informed by two minds theory, which frames behavior change as an intention-behavior gap between 2 neurocognitive systems, was used to elicit data from participants. Interviews explored general exercise perceptions, self-efficacy for exercise, mobile health intervention tailoring, outcome expectations, and PA goals. Thirty interviews from 33 participants were recorded and transcribed verbatim, and deductive and inductive thematic analysis were used using Dedoose.

Results: Physical activity was defined as maintaining daily living activities and addressing health goals. Previous experiences with PA varied among participants and were influenced by chronic illnesses, including human immunodeficiency virus; motivation; work commitments; interest; and social support. Reported barriers to PA included antiretroviral adverse effects, comorbidities, aging, and the COVID-19 pandemic. Changes in health status, body changes, and relationships were identified as benefits of PA. Conversations with healthcare providers supporting exercise goals were perceived to be important but rarely received by the participants.

Conclusion: Understanding how older people with human immunodeficiency virus perceive PA is crucial to developing tailored strategies and structuring service delivery within the healthcare setting to promote a physically active life.

Background: Older patients with chronic heart failure (CHF) are prone to insomnia. Studies have shown that insomnia affects the onset of cognitive frailty and is also strongly associated with depressive symptoms and social support. However, information on how these factors interact to influence cognitive frailty remains underexplored.

Objective: Our aim in this study was to explore the multiple mediating roles of depressive symptoms and social support in the relationship between insomnia and cognitive frailty.

Methods: We recruited 300 hospitalized older patients with CHF to participate in this study. The participants completed the Athens Insomnia Scale, Geriatric Depression Scale, Montreal Cognitive Assessment, FRAIL Scale, and Social Support Rating Scale. The mediation hypothesis was tested using a multiple mediation model and bootstrapping method.

Results: In this study, 44% of the patients experienced insomnia, and 51.3% were in a state of cognitive frailty. Our main findings suggest that insomnia has an indirect effect on cognitive frailty through 2 pathways: the multiple mediating effects of depressive symptoms and social support, and a single mediating effect of depressive symptoms. The direct effect of insomnia on cognitive frailty is also significant.

Conclusions: Older patients with CHF who experience insomnia tend to have more severe depressive symptoms, cognitive frailty, and poor social support. Thus, interventions to recognize insomnia early, improve depressive symptoms, and provide social support may reduce cognitive frailty in older patients with CHF. Longitudinal studies are necessary to further refine our findings and address the limitations of the current study.

Background: Interventions targeting the needs of caregivers of cardiac patients are few, and in most cases, no effect is found on caregivers' well-being. A closer look at the existing interventions will provide a solid foundation for future efforts to develop effective interventions targeted at caregivers of cardiac patients.

Objective: The study's objective was to scrutinize and discuss interventions targeting caregivers of cardiac patients and contribute to reflections that will improve future interventions.

Methods: Systematic scoping of the literature within the field was conducted through a literature search in PubMed, EMBASE, CINAHL, PsycINFO, and Cochrane Library from January 2011 to May 2022. The development of search terms and inclusion criteria was inspired by the Patient problem/population, Intervention, Comparison/Control, and Outcome approach, and the Medical Research Council framework for developing and evaluating complex interventions served as the underlying basis for the analysis.

Results: Eleven articles were included. The interventions reported in the articles were generally not systematically developed and did not include field-specific, methodological, and theoretical reflections. Furthermore, the development process behind the studies seemed not to be transparent.

Conclusions: Lack of systematic methodology and methodological transparency in the reviewed studies hinders further testing of interventions and might explain lack of evidence for effective interventions within the field. More systematic, needs-based, and well-documented interventions targeting caregivers of various kinds of cardiac patients are needed to develop the field to the benefit of caregivers, patients, and society.

Background: The COVID-19 pandemic initially led to discontinuation of the "traditional" center-based cardiac rehabilitation (CR) model. Virtual models emerged as an opportunity to deliver care, with many programs continuing to offer these models.

Objective: The aim of this study was to explore patients' perceptions of virtual models of either hybrid (combining center-based and virtual) or virtual-only CR since the pandemic.

Methods: Men and women who chose to participate in hybrid or virtual CR models between January 2022 and January 2023 were invited to attend 1 of 8 focus group sessions. Focus groups were conducted online until thematic saturation was reached. Transcripts were analyzed using thematic analysis.

Results: Twenty-three patients (48% female; 83% attending hybrid CR) participated in the study. Analysis revealed 12 overarching themes associated with the CR patient journey: pre-CR, namely, (1) importance of endorsement from healthcare providers and (2) need for education/communication while waiting for program initiation; during CR, namely, (3) preference for class composition/structure, (4) need to enhance peer support in the virtual environment, (5) convenience and concerns with virtual sessions, (6) necessity of on-site sessions, (7) safety of the exercise prescription, (8) requirement/obligation for allied health offerings, (9) satisfaction with virtual education, and (10) use of technology to facilitate CR participation; and post-CR, namely, (11) acknowledgment of program completion and (12) need for support/education after program graduation.

Conclusions: Patients require ongoing support from time of referral to beyond CR program completion. Physical, psychosocial, nutritional, and educational supports are needed. Perceptions expressed by patients related to the program model are modifiable, and strategies to address these perceptions should be explored.

Background: Patients with heart failure (HF) experience a wide variety of symptoms. Appropriate recognition of symptoms is important in HF care. The Heart Failure Somatic Perception Scale (HFSPS) measures the presence of HF symptoms and the degree to which physical symptoms are bothersome.

Objective: The aim of this study was to assess the validity and reliability of the Japanese version of the HFSPS.

Methods: Confirmatory factor analysis was used to assess structural validity. Construct validity was assessed using Spearman's rank correlation coefficient to evaluate the association between HFSPS total and subscale scores and global physical health on the Patient-Reported Outcomes Measurement Information System. Internal consistency was assessed using the model-based internal consistency for the HFSPS as a whole and Cronbach α for the subscales.

Results: Participants were 315 Japanese outpatients (72.1% male), with a mean age of 72.9 ± 12.9 years. The result of confirmatory factor analysis was an adequate model fit by adding error correlations. Construct validity was significant for the correlation with global physical health of the Patient-Reported Outcomes Measurement Information System. The model-based internal consistency was 0.95. Cronbach α s for each subscale were 0.88 for dyspnea, 0.60 for chest discomfort, 0.77 for early and subtle symptoms, and 0.77 for edema.

Conclusions: The findings support the use of the HFSPS in a more diverse population, suggesting that it is a reliable and valid instrument in Japanese patients with HF. The HFSPS may provide an accurate assessment of the symptoms experienced by patients with HF in daily life in future educational intervention studies to improve symptom perception and coping behaviors.

Background: Takotsubo syndrome (TS) is preceded by emotional/physical triggers in two-thirds of cases and no trigger in one-third. Information on triggers is typically obtained in the emergency room, and patients rarely have the opportunity to describe in detail the event(s) leading to TS onset.

Objective: This study aimed to conduct a qualitative exploration of patients' narratives regarding the events preceding their TS episode.

Methods: Semistructured interviews inquiring about the presence, type (physical vs emotional), and timing of contiguous events/circumstances relative to symptoms onset were conducted within 2 to 12 weeks of hospital discharge for a TS episode. Interview recordings were transcribed, coded, and analyzed with applied thematic content analysis.

Results: Participants (n = 30; 97% women, 93% White; age, 63 ± 8 years) described equal proportions of acute events (onset < 4 days before admission, 43%) and chronic circumstances (onset > 4 days before admission, 43%) preceding their TS episodes. Acute events included emotional, physical, and mixed (ie, emotional and physical) factors. Chronic circumstances included emotional and mixed factors. Seventy percent of participants perceived these events/circumstances as contributing to their onset of TS.

Conclusions: Patients' narratives of the events contiguous to the TS episode are complex and often include factors that are chronic and/or emotional in nature. Future research should explore the potential importance of emotional aspects and chronic stress in the development of TS.

Background: To prevent cardiovascular disease in adults with type 2 diabetes, it is necessary to identify the factors that affect cardiovascular health behavior.

Objective: The aim of this study was to verify the causal relationship between illness perception and diabetes knowledge as cognitive representations, depression as emotional representations, self-efficacy as cognitive coping, and oral health and cardiovascular health behaviors as behavioral coping strategies. A hypothetical model was established based on a literature review and the self-regulation model.

Methods: In this study, a cross-sectional survey design was used, and the participants were adults 30 years or older who had been given a diagnosis of type 2 diabetes for more than 6 months and were recruited from South Korea. Data from 272 participants were collected through face-to-face interviews or Google surveys in 2021, and analyzed using SPSS 25.0 and AMOS 22.0.

Results: Oral health behavior (β = 0.26, P < .001) and self-efficacy (β = 0.16, P = .048) had a direct effect on cardiovascular health behavior, and illness perception (β = 0.24, P = .018) and depression (β = -0.25, P < .001) had an indirect effect through self-efficacy (β = 0.24, P = .016), with a total explanatory power of 19.1%. Oral health behavior was directly affected by illness perception and self-efficacy, and self-efficacy was directly affected by illness perception, diabetes knowledge, and depression ( P < .05).

Conclusion: To practice cardiovascular health behaviors in adults with diabetes, self-efficacy for diabetes management should be enhanced. To this end, it is necessary to increase illness perception and knowledge, and reduce depression through cardiovascular disease prevention education for them, and the importance of oral health behaviors should also be emphasized.

Background: Pain and anxiety are common postoperative problems that impair recovery and quality of life in patients undergoing coronary artery bypass graft (CABG) surgery. Reflexology is a nonpharmacologic method used to control pain and anxiety.

Objective: The aim of this study was to examine the effects of reflexology hand massage and stroking massage on pain and anxiety in patients in the immediate postoperative period after CABG.

Methods: In this double-blind, randomized, placebo-controlled study, we compared the effects of a 20-minute hand-reflexology massage to placebo stroking massage on pain and anxiety in newly extubated patients in the intensive care unit who had undergone CABG surgery. Pain was measured by visual analog scale and anxiety by the State-Trait Anxiety Inventory before and at 5, 30, and 60 minutes post intervention.

Results: A total of 48 patients were enrolled: 24 in the intervention group and 24 in the placebo. Mean pain scores were significantly reduced in the group who received reflexology compared with the placebo group ( F = 36.569, P = .000). Mean anxiety scores were significantly reduced at 60 minutes for the reflexology group compared with the control group ( P = .000).

Conclusions: We found that hand reflexology massage was effective in reducing pain and anxiety in patients during the immediate postoperative period after CABG.
