Hypertension is a common disease in clinical practice in many countries worldwide. There are currently about 1 billion people with hypertension, and it is estimated that by 2025, this number will reach 1.5 billion 1 . Hypertension is a deteriorative illness owing to its complications that damage target organs such as the heart, eyes, brain, and kidney, in which cardiovascular events are of particular concern. Many evidence show that arterial stiffness is an independent prognostic factor for predict-ting adverse cardiovascular outcomes in hypertensive patients 2 . The gold standard for determining arterial stiffness is to measure pulse wave velocity. Still, this method requires high-technology equipment, making it unavailable to be performed in some medical facilities, especially in the primary health care systems. Another method that correlates with the standard measurement is to evaluate by 24-hour ambulatory blood pressure monitoring. Although it is not a new method, it has adequacy of accessible opportunity, non-invasive feature, and does not require high-technical equipment. As a result, this
Background Tobacco kills more than 8 million people each year, mostly in low- and middle-income countries. In Vietnam, 1 in every 2 male adults smokes tobacco. Vietnam has set up telephone Quitline counseling that is available to all smokers, but it is underused. We previously developed an automated and effective motivational text messaging system to support smoking cessation among US smokers. Objective The aim of this study is to adapt the aforementioned system for rural Vietnamese smokers to promote cessation of tobacco use, both directly and by increasing the use of telephone Quitline counseling services and nicotine replacement therapy. Moreover, we seek to enhance research and health service capacity in Vietnam. Methods We are testing the effectiveness of our culturally adapted motivational text messaging system by using a community-based randomized controlled trial design (N=600). Participants were randomly allocated to the intervention (regular motivational and assessment text messages) or control condition (assessment text messages only) for a period of 6 months. Trial recruitment took place in four communes in the Hung Yen province in the Red River Delta region of Vietnam. Recruitment events were advertised to the local community, facilitated by community health workers, and occurred in the commune health center. We are assessing the impact of the texting system on 6-month self-reported and biochemically verified smoking cessation, as well as smoking self-efficacy, uptake of the Quitline, and use of nicotine replacement therapy. In addition to conducting the trial, the research team also provided ongoing training and consultation with the Quitline during the study period. Results Site preparation, staff training, intervention adaptation, participant recruitment, and baseline data collection were completed. The study was funded in August 2017; it was reviewed and approved by the University of Massachusetts Medical School Institutional Review Board in 2017. Recruitment began in November 2018. A total of 750 participants were recruited from four communes, and 700 (93.3%) participants completed follow-up by March 2021. An analysis of the trial results is in progress; results are expected to be published in late 2022. Conclusions This study examines the effectiveness of mobile health interventions for smoking in rural areas in low- and middle-income countries, which can be implemented nationwide if proven effective. In addition, it also facilitates significant collaboration and capacity building among a variety of international partners, including researchers, policy makers, Quitline counselors, and community health workers.

Background: Premature ventricular contraction (PVC) is a common arrhythmia that causes a large number of clinical symptoms, adversely impacts the quality of life, and can even initiate serious arrhythmias, such as ventricular tachycardia or ventricular fibrillation. The incidence of premature ventricular contraction is higher in hypertensive patients, particularly if concomitant left ventricular hypertrophy (LVH) is present. Objectives: This study was conducted on the characteristics of PVC in hypertensive patients with left ventricular hypertrophy and aimed to evaluate the effect of bisoprolol on PVC in Vietnamese patients with hypertension and LVH. Subjects and Methods: We conducted a study to determine how bisoprolol potency affected PVC management in the group with both high blood pressure and LVH. We selected a convenient sample of all patients who came to the Medical Examination Department at the Can Tho University of Medicine and Pharmacy Hospital and met sampling criteria with hypertension, LVH on echocardiography, and PVC on 12-leads electrocardiogram. Over 2 years, we collected 76 patients who satisfied the above conditions. Out of which, 50 patients were indicated for management with bisoprolol, and 26 patients were excluded from the study, including 7 patients with asthma and 19 patients who had simple PVC on a 24-hour Holter ECG. Data were analyzed with SPSS version Results: Fifty patients participated in the study, of whom 70% were female. It is clear that palpitation was the most prevalent symptom (66%), and 38% of patients had complicated PVC (Lown III-V). When treating PVC with bisoprolol, 50% of patients achieved the treatment goal with a decrease in the number of PVCs of more than 70%, accompanied by symptom relief and eradication of dangerous PVCs. After 4 weeks of treatment, bisoprolol decreased the number of PVCs, heart rate, and blood pressure while also easing PVC-related symptoms (p < 0.05). Conclusion: Low-dose bisoprolol effectively reduces the number of PVCs in hypertensive patients with LVH.
