The Western and Chinese exercise training for blood pressure reduction among hypertensive patients: An overview of systematic reviews.

Hypertension remains the world's leading cause of premature death. Interventions such as exercise, diet modification, and pharmacological therapy remain the mainstay of hypertension treatment. Numerous systematic reviews and meta-analyses demonstrated the effectiveness of western exercises, such as aerobic exercise and resistance exercise, in reducing blood pressure in hypertensive patients. There is recently emerging evidence of blood pressure reduction with Chinese exercises, such as Tai Chi, Baduanjin, and Qigong. The current overview of systematic reviews aims to evaluate the quality and descriptively summarize the evidence for the effectiveness of western and Chinese exercises for hypertension management. Thirty-nine systematic reviews were included in this overview, with 15 of those being on Chinese exercise. Evidence suggests that exercise training, regardless of Western or Chinese exercise, generally reduced both systolic and diastolic blood pressure. High-intensity intermittent training did not further reduce blood pressure when compared to moderate-intensity continuous training. Conflicting results on the effectiveness of blood pressure reduction when comparing Chinese and Western exercise training were observed. This suggests the comparable effectiveness of Chinese exercise training, in particularly Tai Chi, to general or aerobic exercise training in terms of blood pressure reduction. The Chinese exercise modality and intensity may be more suitable for the middle-aged and elderly population.

Developing a competency-based framework for resident-as-teacher.

BACKGROUND/PURPOSE: Residents play an important role as teachers of junior colleagues and medical students. Clinical teaching also helps residents in clinical learning. However, the skills required for residents to be competent teachers are rarely described systemically. Beyond the widely adopted six core competencies for postgraduate training by the Accreditation Council for Graduate Medical Education (ACGME), the teaching competencies should be further developed, and the milestones should be clearly defined to serve as better references for resident training programs. METHODS: Twenty members, including five experts from major teaching hospitals across Taiwan and 15 from a public medical center, were invited to a workgroup to collaboratively develop a competency-based framework. The development process was similar to that suggested by the ACGME. The teaching competencies framework were drafted by an experienced physician educator. The draft was sent to each group member, and feedback was collected. Two workgroup meetings were held for consensus formation. The contents of the teaching competencies of residents were confirmed after two rounds of revision. The outline of the framework was also reported at an international meeting in September 2019. RESULTS: Two core competencies, instruction and assessment, with three sub-competencies and 37 milestones, were adopted in the final edition of resident-as-teacher competencies. The sub-competencies were "dissemination of knowledge" and "teaching of procedural skills" for instruction, and "direct observation and feedback" for assessment. CONCLUSION: A competency-based framework for resident-as-teacher was developed. The framework can be applied in combination with other existing competencies for holistic postgraduate training programs.

Evaluating Teaching Effectiveness of Medical Humanities in an Integrated Clerkship Program by a Novel Prospective Propensity Score Matching Framework.

BACKGROUND: This study aims to rigorously compare the effectiveness of the educational programs of a new integrated clinical clerkship in medicine (3 months) and surgery (3 months) at a cancer center with the conventional subspecialty-based rotations at a tertiary teaching hospital, by this prospective, pre-post comparative method. METHODS: Between 2013-2016, we compared 69 students who had selected the integrated clerkship that emphasized clinical competency and medical humanities training with 138 matched peers who had completed conventional clerkships during the same period. Outcome measures for medical humanities included empathy, patient-centeredness, and other values and skills related to holistic health care professionalism by introducing prospective propensity score matching (PSM). RESULTS: At baseline, no significant between-group differences existed. At the completion of the core clerkships, students receiving the integrative clerkship had significantly higher scores on the Patient-Practitioner Orientation Scale (PPOS) and the Professionalism Climate in Clinical Teaching Environment (PCI), and similar Jefferson Scale of Physician Empathy Student Version (JSPE) scores, as compared with the comparison group. We also found that the students in this program did not perform worse than those in the traditional internship group in the comprehensive and formative OSCE medical clinical skills test. CONCLUSIONS: Our study develops an empirical basis for rigorous evaluation to design medical education to improve the medical humanities values and skills of interns. Features of the new integrated clerkship program that we developed include substantial participation by the students in patient-centered in-hospital culture, as well as reflection, discussion, and feedback on actual clinical cases.

Non-pharmacological management of hypertension.

Hypertension is an insidious disease which predisposes to cardiovascular complications and if not treated properly can lead to various serious complications. Economic limitations, having additional benefits with few or almost no side effects have made non-pharmacological management of hypertension an attractive approach for dealing with hypertension, in developed and developing countries alike. A MEDLINE search was done for relevant references with emphasis on original studies, randomized controlled trials, and meta-analyses for this review paper. Lifestyle modifications including changes in the dietary pattern, adopting special diets with low sodium, saturated fat and high calcium, magnesium and potassium and trying the new methods like time restricted meal intake which work in tandem with the circadian rhythm are opening new vistas in the field of non-pharmacological management of hypertension. Lifestyle modifications that effectively lower blood pressure are increased physical activity, weight loss, limited alcohol consumption, relaxation techniques of Yoga, Acupuncture, Tai chi, mindfulness-based stress-reduction program, and Transcendental Meditation. Air pollution of the surrounding air is linked with poor health outcomes and is a major contributor to the global burden of disease. Fine particulate matter <2.5 µm in diameter (PM2.5) is strongly associated with cardiovascular morbidity and mortality. Short-term PM exposure (hours to weeks) increases the likelihood of adverse cardiovascular events including myocardial infarction, stroke, and heart failure, and longer-term exposure multiplies that risk. Non-pharmacological methods should be initiated early phase of disease and should be continued with medication.

Mental health problems and hypertension in the elderly: Review from the HOPE Asia Network.

The "triple burden" of aging population, hypertension, and mental health problems making elderly in Asia is more vulnerable. There is evidence of a bidirectional relationship between mental health and hypertension, which results in lower quality of life, lower rate of treatment adherence, and higher mortality among elderly individuals. It is essential to overcome known barriers and care for the elderly with high-risk factors in order to address these burdens. This review revealed that elderly with hypertension were more likely to suffer from depression and anxiety. Therefore, debunking myths, creating awareness regarding mental health, and increasing access to mental health resources through holistic community-based programs would greatly reduce such problems and optimize the chances of success in controlling hypertension-related problems.

Cardiovascular Benefits of Acarbose vs Sulfonylureas in Patients With Type 2 Diabetes Treated With Metformin.

Context: Although α-glucosidase inhibitors (AGIs) have been shown to reduce the risk of myocardial infarction in patients with impaired glucose tolerance, the cardiovascular benefits of AGIs in those with type 2 diabetes (T2D) remains unclear. Objective: We compared the clinical outcomes of adding acarbose vs sulfonylureas to metformin therapy in patients with T2D. Design, Setting, and Participants: The study population was drawn from the database of the Diabetes Pay-for-Performance program in Taiwan. Sulfonylureas and acarbose were prescribed to 196,143 and 14,306 patients with T2D, respectively, from 2004 to 2015, who had been treated with metformin. A propensity score-matched cohort study was conducted. The patients were followed up for clinical adverse events of all-cause mortality and hospitalizations of major atherosclerotic events (i.e., myocardial infarction and ischemic stroke), heart failure, or hypoglycemia. Results: A total of 14,306 propensity score-matched pairs (age, 55.8 ± 13.1 years; 47.8% men) were enrolled in the present analysis. Compared with sulfonylureas as the add-on therapy to metformin, the use of acarbose was associated with significantly lower risks of hospitalizations for major atherosclerotic events [hazard ratio (HR), 0.69; 95% CI, 0.52 to 0.91], ischemic stroke (HR, 0.68; 95% CI, 0.49 to 0.94), and hypoglycemia (HR, 0.23; 95% CI, 0.08 to 0.71), after accounting for major confounding factors. Conclusions: In T2D treatment, the use of acarbose as an add-on remedy to metformin was associated with lower risks of major atherosclerotic events, ischemic stroke, and hypoglycemia compared with the use of sulfonylurea as an add-on remedy.

Acupressure effect on sleep quality: A systematic review and meta-analysis.

Acupressure is a non-invasive treatment in which pressure is applied to specific body points. Following public health concerns about poor sleep quality and increasing interest in alternative treatments, a systematic review and a meta-analysis were designed to evaluate the effects of acupressure on the quality of sleep. Ten English (PubMed, CENTRAL, CINAHL etc.) and five Chinese (CNKI, WANFANG etc.) databases were searched and the validity of the eligible studies was critically appraised. Thirty-two eligible randomized controlled trials of moderate to high quality which employed polysomnography, actigraphy, or self-assessment sleep quality tools were included. We conducted a meta-analysis using a random effects model with the Pittsburgh sleep quality index (PSQI) as the primary outcome measure (968 adult patients, 13 trials) for trials investigating the effects of traditional Chinese medicine acupressure compared with standard and sham treatments. We performed subgroup analyses to detect sources of heterogeneity, identify the use of acupoints in different populations and explore the contributions of PSQI domains to the total score change. Comparison with the sham group (7 trials with 385 patients) yielded low heterogeneity and an overall effect of 13%-19% improvement in the PSQI score (MD = -3.41, 95% CI -4.08, -2.75; I2 = 12%). Based on data from four trials (n = 250), sleep latency and sleep duration were most affected. No adverse effects were reported in any of the reviewed trials. Within the limitations of clinical heterogeneity, the results showed that even fragile populations such as the elderly and dialysis patients can benefit from acupressure. Standardized treatment protocols involved 3-5 kg of pressure for one to five minutes per acupoint, delivered three to seven times a week for three to four weeks with the HT7 (Shenmen) acupoint used in most procedures. A high risk of bias due to absence of blinding of patients and personnel remains a serious methodological challenge for acupressure trials and poses a main limitation to presented results. This review has been registered in PROSPERO (registration number CRD42015025013).

Clinical instructors' perception of a faculty development programme promoting postgraduate year-1 (PGY1) residents' ACGME six core competencies: a 2-year study.

Objective The six core competencies designated by Accreditation Council for Graduate Medical Education (ACGME) are essential for establishing a patient centre holistic medical system. The authors developed a faculty programme to promote the postgraduate year 1 (PGY(1)) resident, ACGME six core competencies. The study aims to assess the clinical instructors' perception, attitudes and subjective impression towards the various sessions of the 'faculty development programme for teaching ACGME competencies.' Methods During 2009 and 2010, 134 clinical instructors participated in the programme to establish their ability to teach and assess PGY(1) residents about ACGME competencies. Results The participants in the faculty development programme reported that the skills most often used while teaching were learnt during circuit and itinerant bedside, physical examination teaching, mini-clinical evaluation exercise (mini-CEX) evaluation demonstration, training workshop and videotapes of 'how to teach ACGME competencies.' Participants reported that circuit bedside teaching and mini-CEX evaluation demonstrations helped them in the interpersonal and communication skills domain, and that the itinerant teaching demonstrations helped them in the professionalism domain, while physical examination teaching and mini-CEX evaluation demonstrations helped them in the patients' care domain. Both the training workshop and videotape session increase familiarity with teaching and assessing skills. Participants who applied the skills learnt from the faculty development programme the most in their teaching and assessment came from internal medicine departments, were young attending physician and had experience as PGY(1) clinical instructors. Conclusions According to the clinical instructors' response, our faculty development programme effectively increased their familiarity with various teaching and assessment skills needed to teach PGY(1) residents and ACGME competencies, and these clinical instructors also then subsequently apply these skills.
