Lithofacies and paleogeographical characteristics of late Pleistocene-Holocene deposits are related to three sedimentary system tracts: Lowstand systems tract (LST) corresponds to the low regressive phase from 50 ka BP to 18 ka BP. The sedimentary accumulative space is situated from the boundary of weathering crust to the 100 m water depth. In Ba Lat rivermouth area, the lowstand systems tract is dominated by the alluvial silty sand facies group (arLST); Transgressive systems tract (TST) in Ba Lat rivermouth area constitutes a lithofacies section including three facies in upward direction as follows: (1) Transgressive alluvial silty - sand facies (atTST). (2) Transgressive estuary sandy - mud facies (amtTST). (3) Lagoonal maximum transgressive greenish clay facies (mtTST); Highstand systems tract (HST) in the downstream Red river delta area constitutes a deltaic plain structure consisting of three parts: High subaerial delta, low subaerial delta and subaqueous delta, which had been formed from 5 ka BP.Đặc điểm tuớng đá - cổ địa lý trầm tích Pleistocen muộn-Holocen khu vực cửa sông Ba Lạt gắn liền với ba miền hệ thống trầm tích: Miền hệ thống trầm tích biển thấp (LST) tương ứng với pha biển thoái thấp từ 50.000 năm BP đến 18.000 năm cách ngày nay. Không gian tích tụ của miền hệ thống này được giới hạn từ ranh giới miền xâm thực (vỏ phong hóa) đến độ sâu 100 m nước. Trong khu vực cửa Ba Lạt nhóm tướng aluvi biển thoái thống trị (arLST); Miền hệ thống trầm tích biển tiến (TST) trong khu vực cửa sông Ba Lạt cấu thành một mặt cắt gồm ba tướng từ dưới lên: (1) tướng cát bột aluvi biển tiến (atTST), (2) tướng bùn cát cửa sông biển tiến (amtTST) và (3) tướng sét xám xanh vũng vịnh biển tiến cực đại (mtTST); Miền hệ thống trầm tích biển cao (HST) trong khu vực hạ lưu châu thổ sông Hồng tạo nên một cấu trúc đồng bằng châu thổ bao gồm: Đồng bằng châu thổ cao, Đồng bằng châu thổ thấp và châu thổ ngập nước có tuổi từ 5.000 năm BP

Experience of Kapandji technique in treating Colles’ fracture in central region of Vietnam

Introduction: Extra-articular fractures of the distal radius, known as Colles’ fractures, are very common. The optimal management of Colles’ fracture is still controversial. The Kapandji technique is one option for orthopedic surgeons to maintain reduced fractures, however, the effectiveness of this method is no clear consensus. This study aims to access Colles’ fracture treatment by the Kapandji technique with our experiences. Methods: This prospective study of 33 patients treated with three K-wires intra-focal fractures by the Kapandji procedure for Colles’ fractures at Hue University of Medicine and Pharmacy Hospital in Vietnam between February 2017 and May 2019. The functional outcome of the patients was assessed by the demerit score system of Gartland and Werley, and the quality of reduction was elevated on radiographic as well at 3, 6, 12, and 24 weeks postoperative. Results: 33 patients’ mean age is 54.64 ± 18.00; After 24 weeks of postoperative follow-up, 78.79% presented excellent, 21.21% good, and there are not any fair or poor cases on the functional outcome. All patients achieved complete fracture union at 12 weeks postoperative. The average immediate postoperative radial length was 9.85 mm, the radial inclination was 20.64°, and the volar tilt was 9.2°. Conclusion: The study emphasizes that the Kapandji technique in Colles’ fracture treatment is simple and possible to bring a satisfactory outcome and fast recovery

Medication Adherence of Vietnamese Outpatients with Chronic Diseases during the COVID-19 Pandemic

The purpose of this study was to determine the medication adherence of outpatients with chronic diseases and the association between both patient attitudes and preventive practices regarding COVID-19 and their medication adherence. We performed a cross-sectional study in Vietnam. Medication adherence was determined using the translated and validated Vietnamese version of the General Medication Adherence Scale (GMAS). Patient attitudes and preventive practices regarding COVID-19 were measured using the 5K message of the Vietnam Ministry of Health (facemasks, disinfection, distance, no gatherings, health declarations). The associations between patient characteristics and medication adherence were determined by multivariable regression. The study included 1852 outpatients, and 57.6% of the patients adhered to their medications. Patients who recognized the pandemic’s obstruction of medical follow-ups (OR = 1.771; 95%CI = 1.461–2.147; p < 0.001), who applied ≥2 preventive methods (OR = 1.422; 95%CI = 1.173–1.725; p = 0.001), who were employed (OR = 1.677; 95%CI = 1.251–2.248; p = 0.001), who were living in urban areas (OR = 1.336; 95%CI = 1.090–1.637; p = 0.005,) who possessed higher education levels (OR = 1.313; 95%CI = 1.059–1.629; p = 0.013), or who had ≤2 comorbidities (OR = 1.293; 95%CI = 1.044–1.600; p = 0.019) were more likely to adhere to their medications. The adherence percentage for outpatients with chronic diseases was quite low during the pandemic. Patients who did not recognize the COVID-19 pandemic’s obstruction of medical follow-ups or who had poor preventive practices were less likely to adhere to medications. Healthcare providers should pay more attention to these groups to achieve desired treatment outcomes
