In the 24 hours regime of 80 pregnant unipars women aged 19-45 in a gestation of < 20 weeks without complication, monitored in Hung Vuong Hospital, the average content of Ca of 326g was quantified. Calcium was supplied by milk, in the women calcium supplied group, the mean content of calcium was 422gr, versus 219 gram daily in no calci supplied group. Mean caloric intake was 1.624  613Kcal. Mean protein, carbohydrate and lipid intake were 60  28, 269  94 and 34  26 gram daily respectively. A half of subject number has < 60g protein daily in the diet and 35% among them had a non-protein calories

The study was carried out at Hung Vuong Hospital in 1998 to compare vaginal misoprostol with extra-amniotic balloon to induce abortion in second trimester. Patients were received either 800mcg misoprostol vaginally (n=87) or 500ml of 0.9% NaCl solution inserted into extra-amniotic cavity (n= 93) for induced abortion. Vaginal misoprostol was repeated 24-hourly for maximum of three times. The abortion rates were 98.9% and 96.8% for misoprostol and balloon group, respectively. A second attempt was need in approximate one third of patients in misoprostol group and 10% in balloon group. Side effects of misoprostol were mild and transient. Vaginal misoprostol is as effective as balloon for induced abortion in second trimester. Misoprostol is cheap and easily stored and used. Vaginal misoprostol could be considered as an alternative to balloon for induced abortion

Background: Multiple myeloma is a debilitating malignancy that is part of a spectrum of diseases ranging from monoclonal gammopathy of unknown significance to plasma cell leukemia. Objective: To evaluate the effectiveness in treatment of multiple myeloma with VAD. Subjects and method: A study included 26 patients with multiple myeloma diagnosed according to Tubiana - 1993 criteria, who treated by VAD at Bach Mai Hospital, from January 1998 to December 2006. This was a retrospective combined to longitudinal follow-up examination study. Results: Response rate to treatment was 75%, complete response rate was 41.7%. Remission rate was 91.67%, complete remission rate was 66.7%. The parameters such as hemoglobin, speed of blood precipition in the first hour, globulin, and creatinine changed statistically significant after treatment. The average survival time of the patients was 30.13 \xb1 4.8 months. Survival rate of 1 year after diagnosis was 80%, at 3 years after diagnosis was 26.67% and more than 5 years after diagnosis was 6.67%. Conclusion: VAD had relatively good results in treatment of multiple myeloma.

Background: Monitoring antimalarial drug quality should be conducted regularly in locals to enhance the effect of treatment for malaria \r\n', u'Objective: to study and analyze antimalarial drug quality\r\n', u'Subjects and methods: The study was carried out in 2007 for 5 provinces supported by the Global Fund: Ha Giang, Dien Bien, Thanh Hoa, Quang Tri and Gia Lai. Material were malaria drugs: artesunat, chloroquin, quinine, mefloquin, fansidar\u2026etc\r\n', u'Results and conclusion: The strict supervision on the anti-malarial drug quality by the National Malaria Control Program was very good and no substandard antimalarial drugs were detected. Evaluation of antimalarial drug quality and control was made for finding out the counterfeit drugs through sentinel sites in both private and public sectors. A total of 268 samples were collected, of which 13 samples were found substandard drugs (8 samples collected in private and 5 samples in public sectors). No counterfeit drugs were found. \r\n', u'

Background: The Covid-19 pandemic that occurred at the end of 2019, especially the fourth wave in Vietnam, has affected the world not only in terms of economy, society, and physical health but also affected the mental health of population in general and of medical students in particular. The use of different coping methods may be protective or risk factors for mental health problems. Objectives: 1. To investigate the prevalence of anxiety, stress, and depression among medical students during the Covid -19 pandemic 2. To describe several coping behavior among medical students during the pandemic. Subjects and methods: A descriptive cross-sectional study conducted on 2350 students of medicine programme range from the first year to the sixth year in the school year 2021 - 2022 at Hue University of Medicine and Pharmacy. Using the DASS-21 scale to survey anxiety, depression and stress in research subjects and a self-designed questionnaire to describe the coping methods of medical students. Results: out of 2350 sample, the prevelance of depression, anxiety, and stress was 38%, 33.2%, and 17% respectively. 13.8% had both anxiety and stress, 15.4% had both stress and depression, and 12.8% had a combination of anxiety, depression and stress. Coping behavior was commonly selected including: eating and sleeping regularly as usual (68.1%); doing exercise at home at least 5 days/week and 30 minutes/day (23.9%); 36.5% of students performed their favorite activities under appropriate conditions most of the time or often. In addition, 59.7% of students had learn new things on the internet, 4.5% of students had practiced meditation and relaxation, 2.9% of students had chosen to write a diary and things they were grateful for; 32% had still maintain contacted with friends via video calls, text messages and 34.4% had chosen to participate in volunteer activities. Conclusion: This study highlights a high rate of anxiety, stress and depression among medical students during the fouthth wave of the Covid-19 pandemic. Personal lifestyle changes and social activities were amongst the most comon coping behavior reported.

Objectives: Asymptomatic infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and test re-positivity after a negative test have raised concerns about the ability to effectively control the coronavirus disease 2019 (COVID-19) pandemic. We aimed to investigate the prevalence of COVID-19 asymptomatic and pre-symptomatic infections during the second wave of COVID-19 in Viet Nam, and to better understand the duration of SARS-CoV-2 infection and the dynamics between the evolution of clinical symptoms and SARS-CoV-2 test positivity among confirmed COVID-19 cases. Methods: We conducted a cohort analysis on the first 50 confirmed cases during the second COVID-19 wave in Viet Nam using clinical, laboratory and epidemiological data collected from 9 March to 30 April 2020. Kaplan-Meier estimates were used to assess time to clearance of SARS-CoV-2 infection, and log-rank tests were used to explore factors related to time to SARS-CoV-2 infection clearance. Results: Most cases (58%) had no typical signs or symptoms of COVID-19 at the time of diagnosis. Ten cases (20%) were re-positive for SARS-CoV-2 during infection. Eight cases (16%) experienced COVID-19 symptoms after testing negative for SARS-CoV-2. The median duration from symptom onset until clearance of infection was 14 days (range: 6–31); it was longer in re-positive and older patients and those with pre-existing conditions. Conclusion Asymptomatic and pre-symptomatic infections were common during the second wave of COVID-19 in Viet Nam. Re-positivity was frequent during hospitalization and led to a long duration of SARS-CoV-2 infection.
