Health Professional- and Volunteer-partnered Self-management Support (COMBO-KEY) to Promote Self-efficacy and Self-management Behaviors in People with Stroke: A Randomized Controlled Trial.

BACKGROUND: Multiple systematic reviews have reported that self-management interventions are associated with positive impacts on self-efficacy and health-related quality of life (HRQoL) of people with stroke. PURPOSE: This article reports the effects of an enhanced stroke self-management program. METHODS: Eligible adults with stroke were recruited from community-based organizations and a support group for a two-arm, assessor-blinded randomized controlled trial. Participants in the control group received usual care, while those in the intervention group also received the 8-week self-management program, Coaching Ongoing Momentum Building On stroKe rEcovery journeY (COMBO-KEY), consisting of four individual home visits and five follow-up phone calls, delivered by healthcare professionals and trained volunteers. Assessments were conducted at baseline and after the intervention, for outcomes of self-efficacy, satisfaction with the performance of self-management behaviors, HRQoL, and community reintegration, which were analyzed using generalized estimating equations (GEEs). RESULTS: 134 Participants were recruited [mean age = 64.1 years, standard deviation (SD) = 12.7]. Over 80% of the participants had a first-ever stroke [mean years after first stroke: 4.2 (SD = 5.1)]. The GEE analysis revealed that the intervention group participants showed significantly greater improvements in self-efficacy, satisfaction with their performance of self-management behaviors, HRQoL, and community reintegration at 8-week follow-up with respect to their baseline levels. CONCLUSIONS: The COMBO-KEY program showed effective improvements in recovery outcomes of people with stroke. Future research should explore the inclusion of virtual/hybrid sessions, strategies to assess health conditions of people with stroke via online modes, and assessment of goal attainment and actual performance of self-management behaviors.

Self-management is the active involvement of a person in managing their overall needs for being able to live well with a chronic condition. Self-management interventions have shown to improve the recovery outcomes of people with stroke. We developed an 8-week long enhanced self-management program "COMBO-KEY" delivered by healthcare professionals and trained volunteers, consisting of individual home visits, follow-up phone calls, peer sharing videos, and enriched resources sharing through a website and a reference guide, aimed at promoting self-efficacy, and self-management behaviors of people with stroke. In this study, 134 adults with stroke were recruited and randomized to either receive the COMBO-KEY program or continue to receiving usual care only. Participants receiving the program showed greater improvements in self-efficacy and self-management behaviors with increased quality of life and reintegrating back to the community after eight weeks compared to the participants receiving usual care. The results highlighted the positive role of a health coaching approach, whereby healthcare professionals, and trained volunteers provide self-management support, to improve the recovery of people with stroke.

A randomized clinical trial of mindfulness meditation versus exercise in Parkinson's disease during social unrest.

Clinical practice guidelines support resilience training and exercise for patients with Parkinson's disease (PD). This assessor-blinded, randomized clinical trial aimed to compare the effects of a modified mindfulness meditation program versus stretching and resistance training exercise (SRTE) in patients with mild-to-moderate PD. A total of 126 potential participants were enrolled via convenience sampling, of which 68 eligible participants were randomized 1:1 to receive eight weekly 90-min sessions of mindfulness meditation or SRTE. Compared to the SRTE group, generalized estimating equation analyses revealed that the mindfulness group had significantly better improvement in outcomes, particularly for improving depressive symptoms (d, -1.66; 95% CI, -3.31 to -0.02) at week 8 and maintaining emotional non-reactivity at week 20 (d, 2.08; 95% CI, 0.59 to 3.56). Both groups demonstrated significant immediate, small-moderate effects on cognition (effect size [d] = 0.36-0.37, p = 0.006-0.011). Compared with the SRTE, mindfulness meditation appeared to be a feasible and promising strategy for managing depressive symptoms and maintaining emotional stability, with comparable benefits on cognitive performance. To combat the psychospiritual and cognitive sequelae of social unrest and COVID-19 pandemic, the integration of mindfulness training into motor-oriented PD rehabilitation protocols is recommended to strengthen the resilience and minimize the psycho-cognitive comorbidities among patients with mild-to-moderate PD.Trial Registration: HKU Clinical Trials Registry identifier: HKUCTR-2681.

Effects of Mindfulness Yoga Versus Conventional Physical Exercises on Symptom Experiences and Health-related Quality of Life in People with Parkinson's Disease: The Potential Mediating Roles of Anxiety and Depression.

BACKGROUND: Although several studies have reported positive effects of mind-body exercises on symptom management and health-related quality of life (HRQOL) of people living with Parkinson's disease (PD), it is not known whether these effects are attributable to a change in anxiety and depression. PURPOSE: To compare the effects of mindfulness yoga to conventional stretching exercises in a randomized controlled trial while examining potentially mediating effects of anxiety and depression. METHODS: 138 adults with PD were randomized to eight weekly yoga (n = 71) or stretching (n = 67) sessions. Symptom experiences, anxiety and depression, and HRQOL outcomes were assessed at baseline, immediate post-intervention, and 3-month post-intervention. RESULTS: Generalized estimating equation analyses revealed that, compared to stretching, yoga significantly improved patients' nonmotor (time-by-group interaction, T1:ß = -1.99, p = .008; T2:ß = -2.86, p < .001) and motor (time-by-group interaction, T1:ß = -1.77, p = .03) symptom experiences. The mediation analysis found that the changes in anxiety and depression were the mediators in the associations between non-motor experience and HRQOL; while only the changes in depression were found to be the mediator in the relationship between motor experience and HRQOL. CONCLUSIONS: Yoga is superior to conventional stretching exercises in improving nonmotor and motor symptoms in daily living. Reduced anxiety and depression play a role in mediating the positive effects of the mindfulness yoga intervention. To optimize HRQOL, rehabilitation should reinforce psychological care in addition to pharmacological treatments and physical relief of PD symptoms. Future studies are needed to identify strategies for facilitating the implementation and sustainability of mind-body rehabilitation to enhance the quality of care for PD.

Coaching Ongoing Momentum Building On stroKe rEcovery journeY ('COMBO-KEY'): a randomised controlled trial protocol.

INTRODUCTION: Systematic reviews reporting self-management interventions are associated with significant improvements in stroke survivors' self-efficacy, health-related quality of life (HRQoL) and independence. However, common barriers such as transportation and availability of carers were identified. Health coaching is suggested as an innovative and cost-effective care model with potential benefits in managing chronic diseases. A randomised controlled trial is proposed to evaluate the effectiveness of an enhanced self-management programme by health coaches on stroke survivors' recovery outcomes. METHODS AND ANALYSIS: All adult community-dwelling stroke survivors with a modified Rankin Scale Score ≥3 will be recruited from a community rehabilitation network. Eligible participants will be randomly allocated to receive either the enhanced stroke self-management programme (Coaching Ongoing Momentum Building On stroKe rEcovery journeY [COMBO-KEY]) plus usual care or usual care only. COMBO-KEY is an 8-week programme underpinned by Bandura's principles of self-efficacy and outcome expectation. It consists of four home visits and five phone-coaching sessions delivered by trained health coaches. Each participant will receive a resource package containing a workbook, a quick reference guide, a planning toolkit and 15 videos of peer survivors' stroke survival experience. Survivors' outcomes include self-efficacy, outcome expectation and satisfaction with performance of self-management behaviours, HRQoL, depressive symptoms and community reintegration. Assessment will be conducted at baseline and immediately after completing the programme. Generalised estimating equations' model will be used to analyse the data. DISCUSSION: It is anticipated that the programme will build community capacity in supporting stroke survivors. The results will shed light on integrating the programme into the current stroke rehabilitation services. ETHICS AND DISSEMINATION: The Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee has approved this protocol (CREC Ref. No.: 2018.009). Written informed consent will be obtained from all participants. Study results will be disseminated through peer-reviewed journals and presentations at local and international conferences.

Effects of Mindfulness Yoga vs Stretching and Resistance Training Exercises on Anxiety and Depression for People With Parkinson Disease: A Randomized Clinical Trial.

Importance: Clinical practice guidelines support exercise for patients with Parkinson disease (PD), but to our knowledge, no randomized clinical trials have tested whether yoga is superior to conventional physical exercises for stress and symptom management. Objective: To compare the effects of a mindfulness yoga program vs stretching and resistance training exercise (SRTE) on psychological distress, physical health, spiritual well-being, and health-related quality of life (HRQOL) in patients with mild-to-moderate PD. Design, Setting, and Participants: An assessor-masked, randomized clinical trial using the intention-to-treat principle was conducted at 4 community rehabilitation centers in Hong Kong between December 1, 2016, and May 31, 2017. A total of 187 adults (aged ≥18 years) with a clinical diagnosis of idiopathic PD who were able to stand unaided and walk with or without an assistive device were enrolled via convenience sampling. Eligible participants were randomized 1:1 to mindfulness yoga or SRTE. Interventions: Mindfulness yoga was delivered in 90-minute groups and SRTE were delivered in 60-minute groups for 8 weeks. Main Outcomes and Measures: Primary outcomes included anxiety and depressive symptoms assessed using the Hospital Anxiety and Depression Scale. Secondary outcomes included severity of motor symptoms (Movement Disorder Society Unified Parkinson's Disease Rating Scale [MDS-UPDRS], Part III motor score), mobility, spiritual well-being in terms of perceived hardship and equanimity, and HRQOL. Assessments were done at baseline, 8 weeks (T1), and 20 weeks (T2). Results: The 138 participants included 65 men (47.1%) with a mean (SD) age of 63.7 (8.7) years and a mean (SD) MDS-UPDRS score of 33.3 (15.3). Generalized estimating equation analyses revealed that the yoga group had significantly better improvement in outcomes than the SRTE group, particularly for anxiety (time-by-group interaction, T1: ß, -1.79 [95% CI, -2.85 to -0.69; P = .001]; T2: ß, -2.05 [95% CI, -3.02 to -1.08; P < .001]), depression (T1: ß, -2.75 [95% CI, -3.17 to -1.35; P < .001]); T2: ß, -2.75 [95% CI, -3.71 to -1.79; P < .001]), perceived hardship (T1: ß, -0.92 [95% CI, -1.25 to -0.61; P < .001]; T2: ß, -0.76 [95% CI, -1.12 to -0.40; P < .001]), perceived equanimity (T1: ß, 1.11 [95% CI, 0.79-1.42; P < .001]; T2: ß, 1.19 [95% CI, 0.82-1.56; P < .001]), and disease-specific HRQOL (T1: ß, -7.77 [95% CI, -11.61 to -4.38; P < .001]; T2: ß, -7.99 [95% CI, -11.61 to -4.38; P < .001]). Conclusions and Relevance: Among patients with mild-to-moderate PD, the mindfulness yoga program was found to be as effective as SRTE in improving motor dysfunction and mobility, with the additional benefits of a reduction in anxiety and depressive symptoms and an increase in spiritual well-being and HRQOL.

The effects of yoga versus stretching and resistance training exercises on psychological distress for people with mild-to-moderate Parkinson's disease: study prxotocol for a randomized controlled trial.

BACKGROUND: Psychological distress is prevalent among people with Parkinson's disease (PD) and aggravates their motor symptoms, thereby leading to increased disability, high healthcare costs, and poor health-related quality of life (HRQoL). The under-recognition and adverse effects of the pharmacological management of anxiety and depression among the PD population are considerable. Thus, adopting a Complementary and Alternative Management (CAM) approach to address this problem is important. Yoga, one of the most common "mind-body" CAM therapies, can improve the psychological wellbeing of people with chronic illnesses. However, limited research on the effects of yoga in people with PD has been conducted. This study will determine the effects of yoga on the psychological wellbeing of people with mild-to-moderate PD and will compare these effects with those of stretching and resistance training exercises. METHODS: A community-based, single-blind, randomized trial will be conducted. A total of 126 subjects will be recruited and randomly divided into yoga (n = 63) or stretching and resistance exercise (n = 63) groups. For 8 weeks, the yoga group will receive a weekly 90-min session of yoga, and the control group will receive a weekly 60-min session of stretching and resistance exercises. The primary outcome will be the level of psychological distress measured using the Hospital Anxiety and Depression Scale. The secondary outcomes will include the severity of motor symptoms measured by the Movement Disorders Society - Unified Parkinson's Disease Scale - Part III Motor Examination; mobility, balance, and fall risk measured by the Timed Up and Go test; spiritual wellbeing measured by the Holistic Wellbeing Scale; and HRQoL measured by the Parkinson's Disease Questionnaire-8. Assessment will be conducted at baseline, 8th, and 20th weeks of follow-ups. DISCUSSION: This study will be the first randomized trial to compare the effect of yoga versus stretching and resistance training exercises in a PD population. Results will contribute to the value of yoga as a therapeutic option for managing psychological distress in PD patients. Multiple outcomes including psychological, physiological, and spiritual and HRQoL will also be measured to elucidate the potential mechanisms of yoga. The effect of yoga on people with chronic illnesses will further be elucidated. This information should contribute to future research, practice, and policy related to PD management.

A pilot evaluation of Arthritis Self-Management Program by lay leaders in patients with chronic inflammatory arthritis in Hong Kong.

The objectives of this paper are to evaluate the efficacy of a community-based lay-led Arthritis Self-Management Program (ASMP) among patients with chronic inflammatory arthritis and evaluate the effectiveness of "shared care collaboration" between hospital and community. We trained 17 lay leaders and recruited patients with chronic inflammatory arthritis via a new shared-care model between hospital rheumatology centers and community organizations. Participants were allocated to interventional group or a wait list control group. Evaluations were completed before, after (6 weeks), and 3 months after ASMP. We performed analysis of covariance with adjustment with age, sex, marital status, education, employment, duration of illness, and disability at baseline. A total of 65 participants and 32 controls completed the study. The mean (SD) age and duration of illness were 52.0 (11.4) and 5.6 (7.3) years, 90.7 % were female, 80.4 % had rheumatoid arthritis; 25.8, 53.6, and 12.4 % referrals were from hospitals, community organizations, and patient self-help groups, respectively. The interventional group had significantly less pain (p = 0.049 at 6 weeks), used more cognitive coping methods (p = 0.008 at 6 weeks, p = 0.041 at 3 months) and practiced more aerobic exercise (p = 0.049 at 6 weeks, p = 0.008 at 3 months) after adjustment of covariance. The interventional group had a trend of improvement in self-efficacy, fatigue, self-rated health, and health distress. A community-based lay-led ASMP showed positive beneficial effects on participants with chronic inflammatory arthritis. Shared-care collaboration between hospitals, community organizations, and patient self-help groups was demonstrated.

Agrobacterium-mediated high-frequency transformation of an elite commercial maize (Zea mays L.) inbred line.

KEY MESSAGE: An improved Agrobacterium -mediated transformation protocol is described for a recalcitrant commercial maize elite inbred with optimized media modifications and AGL1. These improvements can be applied to other commercial inbreds. This study describes a significantly improved Agrobacterium-mediated transformation protocol in a recalcitrant commercial maize elite inbred, PHR03, using optimal co-cultivation, resting and selection media. The use of green regenerative tissue medium components, high copper and 6-benzylaminopurine, in resting and selection media dramatically increased the transformation frequency. The use of glucose in resting medium further increased transformation frequency by improving the tissue induction rate, tissue survival and tissue proliferation from immature embryos. Consequently, an optimal combination of glucose, copper and cytokinin in the co-cultivation, resting and selection media resulted in significant improvement from 2.6 % up to tenfold at the T0 plant level using Agrobacterium strain LBA4404 in transformation of PHR03. Furthermore, we evaluated four different Agrobacterium strains, LBA4404, AGL1, EHA105, and GV3101 for transformation frequency and event quality. AGL1 had the highest transformation frequency with up to 57.1 % at the T0 plant level. However, AGL1 resulted in lower quality events (defined as single copy for transgenes without Agrobacterium T-DNA backbone) when compared to LBA4404 (30.1 vs 25.6 %). We propose that these improvements can be applied to other recalcitrant commercial maize inbreds.

Cognitive-behavioral treatment groups for people with chronic physical illness in Hong Kong: reflections on a culturally attuned model.

This study describes and evaluates a cognitive-behavioral treatment group for people with chronic physical illness in Hong Kong. We developed a group protocol based on the understanding that Chinese people generally prefer a structured group format, expect group leaders to be active and directive, and are not used to expressing opinions and emotions in groups. The experimental and waitlist control groups had 38 and 35 participants, respectively. A standardized questionnaire was administered to all participants before and after the group treatment. Results suggest that members of the experimental group showed improvements in mental health, negative automatic thoughts, and negative emotions when compared to those in the waitlist control groups, and at the end of group treatment. Implications for designing and running a culturally attuned CBT group for Chinese people are discussed.
