Blood pressure screening results from May Measurement Month 2019 in Vietnam.

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. May Measurement Month (MMM) is a global initiative to raise awareness of high BP and act as a temporary solution to the lack of screening programmes worldwide. We aimed to screen for hypertension and cardiovascular risk factors in people aged ≥18 years in the community, thereby defining the proportion of subjects with elevated BP and assess the awareness and the effectiveness of its treatment. An opportunistic cross-sectional survey of volunteers aged ≥18 years was carried out in May 2019. Blood pressure measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. From May 2019 to June 2019, through 10 cities/provinces in Vietnam, 25 887 individuals with mean age 48.7 (SD ±17.7) years were screened. After multiple imputations, 8758 (33.8%) had hypertension. Of individuals not receiving antihypertensive medication, 3025 (15.0%) were hypertensive. Of individuals receiving antihypertensive medication, 2800 (48.8%) had uncontrolled BP. Raised BP [systolic BP (SBP) ≥140 mmHg and/or diastolic BP (DBP) ≥90 mmHg] was also associated with additional risk factors including smoking, alcohol intake, previous hypertension in pregnancy, and obesity. May Measurement Month 2019 was the most extensive BP screening campaign ever undertaken in Vietnam. Undiagnosed and uncontrolled hypertension in Vietnam remains a substantial health problem. Local campaigns applying standardized methods such as MMM 2019 will be beneficial to screen for the significant number of individuals with raised BP and increase the awareness of hypertension.

Outcomes of thoracoscopic clipping versus transcatheter occlusion of patent ductus arteriosus: randomized clinical trial.

AIM: To compare outcomes of thoracoscopic clipping (TC) versus transcatheter occlusion (TO) for patent ductus arteriosus (PDA). PATIENTS AND METHODS: One hundred patients were enrolled in the study from May 2010 to December 2011. Those patients were randomized into 2 groups: group one received TC, group two received TO. RESULT: There were no significant differences concerning width or length of the ductus (P>0.05). However the median age and median weight of patients in the TO group were greater than in the TC group (P<0.05). Mean operative time was 32 ± 12 min in the TC group versus 20 ± 3 min in the TO group (P<0.05). There were no deaths in either group. There were no complications in the TC group whereas three patients in the TO group had complications and required subsequent operation. Median postoperative stay was 3.5 days (IQR: 3.0-4.3) in the TC group versus 3 days (IQR: 2.0-4.0) in the TO group (P<0.05). There was no residual shunting in either group. Average cost for one patient was $645 ± 232 in the TC group versus $1,260 ± 204 in the TO group (P<0.001). CONCLUSION: Thoracoscopic clipping is safer than transcatheter occlusion for PDA repair, with the same effectiveness and lower cost.

Thoracoscopic repair for congenital diaphragmatic hernia: experience with 139 cases.

PURPOSE: To analyze indications and to present details of surgical technique and outcomes of thoracoscopic repair for congenital diaphragmatic hernia (CDH) in 139 patients. METHODS: We reviewed medical records of all patients with CDH who underwent thoracoscopic repair by the same surgical team from June 2001 to October 2009. Patients were placed in the lateral decubitus position. The operations were performed using three trocars. Pleural insufflation with carbon dioxide was maintained at a pressure of 2-6 mm Hg. The hernia defect was repaired using nonabsorbable interrupted sutures with extracorporeal knots. A prosthetic patch was used when direct closure of the hernia defect was not feasible. RESULTS: There were 139 patients, including 91 boys and 48 girls. Seventy-five patients were newborns, and 64 were infants or children. The hernia was located on the left side in 113 patients (81.3%) and on the right side in 26 patients (18.7%). The mean operative time for thoracoscopic approach was 66 ± 27 minutes. Conversion was required in 11 patients (7.9%) from 2001 to 2007. There were no conversions in 2008 or 2009. A prosthetic patch was used in 7 patients. There were 14 postoperative deaths (10%). Follow-up was obtained in 114 patients, ranging from 1 to 84 months (mean 26.3 ± 24.7 months). Five patients had recurrence (3.6%). CONCLUSIONS: Thoracoscopic repair is feasible and safe for children with CDH, including newborns. The conversion rate decreased, and indications increased with surgical team experience.

Thoracoscopic pericardiectomy for purulent pericarditis: experience with 21 cases.

PURPOSE: We present our experience in performing thoracoscopic pericardiectomy for purulent pericarditis in 21 children. MATERIALS AND METHODS: Pericardiectomy was carried out using one optical trocar and two operating trocars. Pleural insufflation with carbon dioxide was maintained at 2-4 mm Hg. Anterior pericardiectomy was performed from the left phrenic nerve to the right border of the sternum to free the anterior part of the heart, notably the cardiac apex and the original area of the great vessels. Purulent debris was removed prior to detaching the epicardial peel. RESULTS: This study included 21 patients. Their mean age was 8 years. The time from onset of the disease to surgery ranged from 4 to 34 days (average, 15.2 days). Operative times ranged from 50 to 180 minutes (average, 100 minutes). There were no intraoperative or postoperative complications. All symptoms of cardiac tamponade disappeared immediately postoperatively. Follow-up ranged from 4 to 15 months and showed normal clinical manifestations, echocardiographs, and chest x-rays in all children. CONCLUSION: Thoracoscopic pericardiectomy with removal of a generous amount of the pericardium is feasible and safe for purulent pericarditis.
