This study is aimed to investigate the activity of lymphocytes of recurrent spontaneous aborters, their response to phytohemagglutinin (PHA) mitogen was studied by comparing with that of normal pregnancy and normal non-pregnancy women. The results are as follows: there is no or a significant decrease of suppression of lymphoblast transformation in recurrent spontaneous abortion comparing to that of normal pregnancy women. It should be considered all of three parameters: absolute counts of OD with PHA, non-PHA and stimulation index as a general analysis for lymphoblast transformation.

We have studied 37 early pregnancy women, divided into 2 groups of: 22 women of recurrent spontaneous abortion and 15 women with normal pregnancy. By using micro lymphocytotoxicity technique in comparison between sera of the tested women and lymphocytes panel of 20 healthy women, this study shows higher incidence and levels of lymphocytotoxic antibodies in women with recurrent pregnancy failure than in normal women.

To study the immunologic characteristics of miscarriage, 34 women admitted with recurrent spontaneous abortion and 40 healthy women in the first trimester of pregnancy were investigated. The total results are as follows:-The total WBC count, especially granulocytes was raised significantly in RSA group.- No change was seen in the lympho T and lympho B cell numbers as well as lympho T CD4, lympho T CD8 cell numbers. However, the ratio CD4/CD8 was decreased in RSA group. Although it is not known if these changes are the cause or the effect, it would appear that immunologic abnormalities are associated with recurrent spontaneous abortion.

Background: DNA biosensor is based on micro-nano technologies aimed at developing a rapid diagnostic device of infectious diseases and diseases related to genetic change. Biosensors are compact size, high sensitivity and low cost\r\n', u'Objectives: To evaluate effect of biosensor in detecting specific gene fragments of Herpes Simplex virus type 1 and 2 (HSV)\r\n', u'Subjects and method: The electrical signals were recognized by means of transducer and from electrochemical detection of the hybridization between the probe 5\ufffd?AT CAC CGA CCC GGA GAG GGA C-3\ufffd?which were covalently immobilised onto the surface of micro electrodessensors in 3-aminopropyltri-ethoxysilance (APTS)-the conducting polymer matrix and the target (specific DNA sequences of HSV in the sample.\r\n', u'Results: The DNA sensor offers a very high sensitivity, a fast response time, less than 1 min with the DNA target concentration up to 1nM in aqueous media at room temperature.However, in order to detect target DNA in the real samples, samples must be extracted DNA, denatured DNA sequences from a double fiber to single fiber.

In this report we describe a new approach in HIV sentinel surveillance that was piloted in Viet Nam in 2009 and is currently being rolled out in all provinces. It comprises a brief behavioural questionnaire added to the HIV sentinel surveillance surveys conducted routinely among people who inject drugs, female sex workers and men who have sex with men. Timely reporting of data from this system has resulted in improvements to HIV prevention efforts for most at-risk populations.

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.

Abstract Objective: The World Health Organization’s guidelines on viral hepatitis testing and treatment recommend prioritizing high prevalence groups. Hepatitis C virus (HCV) infection disproportionately affects people who inject drugs and men who have sex with men, but data on female sex workers (FSW) are limited. The study aimed to determine active HCV infection and risk factors associated with HCV exposure among Vietnamese FSW. Methods: We surveyed 1886 women aged ≥ 18 years from Haiphong, Hanoi and Ho Chi Minh City who had sold sex in the last month. We tested for HCV antibody and HCV core antigen as markers for exposure to HCV and active infection, respectively. Results: Across these provinces, high prevalence of HCV exposure (8.8–30.4%) and active infection (3.6–22.1%) were observed. Significant associations with HCV exposure were HIV infection (aOR = 23.7; 95% CI: 14.8–37.9), injection drug use (aOR = 23.3; 95% CI: 13.1–41.4), history of compulsory detention (aOR = 2.5; 95% CI: 1.4–4.2) and having more than 10 sex clients in the last month (aOR = 1.9; 95% CI: 1.2–3.2). Among FSW who reported never injecting drugs, HIV infection (aOR = 24.2; 95% CI: 14.8–39.4), a history of non-injection drug use (aOR = 3.3, CI: 1.8–5.7), compulsory detention (aOR = 2.2; 95% CI: 1.2–4.0) and having over 10 sex clients in the last month (aOR = 2.2, 95% CI: 1.3–3.7) were independently associated with HCV exposure. Discussion: FSW have elevated HCV risks through sex- and drug-related pathways. These findings highlight the need to offer FSW-targeted HCV interventions and ensure their access to HIV prevention and treatment.

Objective: This study sought to estimate the prevalence of erectile dysfunction (ED) and to ascertain risk factors among Vietnamese men with diabetes. Methodology: One hundred and fifty one diabetic patients were recruited from the People’s Hospital 115 between August 2011 and March 2012. They were asked to complete a self-administered questionnaire that included the International Index for Erectile Function Questionnaire (IIEF-5) and the World Health Organization (WHO) - Five Well-being Index. Medical history, anthropometric measures, and laboratory test results were recorded. ED was classified based on the IIEF-5 total score. Results: Of the 151 diabetic men, 135 (89%) completed the IIEF-5. The overall prevalence of ED was 84%; majority (65%) were classified as mild to moderate, while 10% were considered severe. The prevalence of ED was higher among those with peripheral neuropathy [adjusted odds ratio (OR) 5.22, 95% confidence interval (CI) 1.14-21.89] and longer duration of diabetes (OR 1.11, 95% CI 1.00-1.24). Conclusion ED represents a prevalent major complication among men with type 2 diabetes. The presence of peripheral neuropathy and long duration of diabetes may be useful indicators of ED.
