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: β, −1.79 [95% CI, −2.85 to −0.69;P = .001]; T2: β, −2.05 [95% CI, −3.02 to −1.08;P < .001]), depression (T1: β, −2.75 [95% CI, −3.17 to −1.35;P < .001]); T2: β, −2.75 [95% CI, −3.71 to −1.79;P < .001]), perceived hardship (T1: β, −0.92 [95% CI, −1.25 to −0.61;P < .001]; T2: β, −0.76 [95% CI, −1.12 to −0.40;P < .001]), perceived equanimity (T1: β, 1.11 [95% CI, 0.79-1.42;P < .001]; T2: β, 1.19 [95% CI, 0.82-1.56;P < .001]), and disease-specific HRQOL (T1: β, −7.77 [95% CI, −11.61 to −4.38;P < .001]; T2: β, −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.

Ageing has been recognized as one of the most critically important health-care issues worldwide. It is relevant to Asia, where the increasing number of older populations has drawn attention to the paramount need for health-care investment, particularly in end-of-life care. The advocacy of advance care planning is a mean to honor patient autonomy. Since most East Asian countries are influenced by Confucianism and the concept of ‘filial piety,’ patient autonomy is consequently subordinate to family values and physician authority. The dominance from family members and physicians during a patient’s end-of-life decision-making is recognized as a cultural feature in Asia. Physicians often disclose the patient’s poor prognosis and corresponding treatment options to the male, family member rather to the patient him/herself. In order to address this ethical and practical dilemma, the concept of ‘relational autonomy’ and the collectivism paradigm might be ideally used to assist Asian people, especially older adults, to share their preferences on future care and decision-making on certain clinical situations with their families and important others. In this review article, we invited experts in end-of-life care from Hong Kong, Indonesia, Japan, South Korea, Singapore and Taiwan to briefly report the current status of advance care planning in each country from policy, legal and clinical perspectives. According to the Asian experiences, we have seen different models of advance care planning implementation. The Asian Delphi Taskforce for advance care planning is currently undertaken by six Asian countries and a more detailed, culturally sensitive whitepaper will be published in the near future.

Advance care planning (ACP) is the process of ongoing communication among patients, family and health care professionals regarding what plans for future care are preferred in the event that patients become unable to make their own decisions. Clinicians play an important role in ACP as both initiators and decision coaches. However, lack of training for clinicians has frequently been reported as the reason for low involvement in ACP discussions - hence the present review evaluates the effectiveness of ACP training programs for healthcare professionals to guide the development of novel training programs for them in the future. A literature search for intervention studies was conducted independently by two reviewers in July 2018. Participants included all healthcare professionals working with adult patients suffering from terminal illness. The primary outcomes were the professionals’ knowledge of and attitudes towards ACP, and self-perceived competence in ACP conversations. The Effective Public Health Practice Project appraisal tool was used to examine the quality of the studies included. A total of 4025 articles were identified, and ten eligible articles, covering 1081 participants, were included in the review. However, there is a lack of high quality randomized controlled trials of providing ACP training for nurses working in non-palliative care hospital settings. The overall quality of the intervention studies was moderate. All the studies included used instructional sessions in their interventions, while some contained group discussion, role-play and the use of advanced technology. The training programs increased the knowledge, attitudes towards shared decision-making, perceived communication skills, confidence, comfort and experiences concerned with discussing end-of-life (EOL) issues. Patient advocacy, job satisfaction and perceived level of adequate training for EOL care were improved. The use of ‘decision aids’ was rated as acceptable and clinically useful. Training for healthcare professionals in ACP has positive effects on their knowledge, attitude and skills. The use of decision aids and advanced technology, instructional sessions with role play, training content focused on ACP communication skills and the needs and experience of patient in the ACP process, and a values-based ACP process are all those factors that made the ACP training programs effective.
