Background: Training community-oriented general practitioners with the aims to provide the medical knowledge and skills of working in the community for medical students is appropriate with the socioeconomic context in Vietnam. Objectives: To evaluate the acceptance of the community in two districts Kim Bang (Ha Nam province) and Dong Hy (Thai Nguyen province) on field training for medical students. Subjects and method: The cross - sectional study was carried out on 300 households that were chosen randomly from 2 rural districts on April 2006. The heads of households were interviewed by open - ended questionnaires. Another 120 key informants from these two districts were invited to participate in a focus group discussion. Results: 81% of households voluntarily participated in the organization of field training for the medical students. More than 97% households paid attention to the medical students\u2019 information about health care and environmental hygiene. With medical community-based education, the people from communities receives\u2019 improvement in their knowledge of child care and personal hygiene in order to prevent diseases. Conclusion: Being exposed to health problems in communities, medical students can enhance their working and communication skills. People in the communities had a chance to improve their knowledge of disease preventions.

Background: \r\n', u'In the antituberculosis chemotherapy, shortening treatment course, and applying new high effective methods are top prioritized. Of which,the immunotherapy with M vaccea an environmental saprophyte, combined with the antituberculosis medicines all over the world has been applied since 1985, aimed to enhance the host immune responses.\r\n', u'Objectives:\r\n', u'To evaluate the results after 6 months of shortened course anittuberculosis chemotherapy by combining the immunotherapy withM vaccae.\r\n', u'Subjects and method: \r\n', u'233 newly diagnosed pulmonary tuberculosis patients with AFB smear (+) selected from Centers for Tuberculosis Control in some districts of Ha Tay and Ha Noi. They are 15 above, and not the pregnant, breastfeeding, diabetes, HIV infections, and hepatitis B (Unnecessary) \r\n', u'Dividing randomly into 2 groups, group A was in treatment of the standard 8 month chemotherapy regimen, and group B was treated in a shortned 6 month chemotherapy regimen in combination with immunotherapy by using M. vaccae vaccine. \r\n', u'Results:\r\n', u'The rates of AFB (-) sputum of group B were 98,2% and 100% respectively, the rates of the group A were 97,4% and 99% respectively after 2 and 6 months of treatment. There are 88.5% and 100% for group B, 85.6% and 98.8% for group A at the same time to achieve a negative sputum culture for M. tuberculosis. IgM responses against M. tuberculosis sonicated antigen before and after the follow-up time in Group A are not changed, whereas this level of the immunotherapy group had reduced significantly at the 6th moth (P<0.05). There is no responses in IgC to M. tuberculosis of both groups during the same follow-up period. The mean weight of patients in group B was higher than that of group A after 2 and 6 months of treatment.\r\n', u'Conclusion:\r\n', u'M. vaccae vaccine brings good benefits when be combined with the chemo-immunotherapy for newly diagnosed pulmonary tuberculosis patients with AFB smear (+). The negative sputum indicators and clinic improvements in the chemo- immunotherapy group of treatment are better than that of chemotherapy only. This study created more effective method for treating tuberculosis infection.\r\n', u'

Background: In Vietnam, the HIV/AIDS pandemic is quickly spreading, almost totally in young people and among injecting drug users.The transition phase from smoking to injecting is very important for the life of injecting drug users because it is a risk factor of disease transmission. Objectives: (1) To analyze the transition phase from smoking/sniffing to injecting of the young male heroin users in Ha Noi. (2) To describe some factors related to the transition phase in these people. Subjects and method: A cross-sectional study carried out from September 2004 to September 2005 at 9 districts in Ha Noi city. The subjects were 1115 young men aged 16 to 29 years, who has been living in Ha Noi for over 6 months and smoked/sniffed heroin within the last 30 days. Results and conclusions: The average time of drug user in the 1115 subjects was 4.7 years. The majority started using drug at the age of 18.4 +/- 3.1 years. In which, 71 % consume the drugs by injection. The average time from smoking to injecting is 2.49 +/- 2.2 years. The main reasons for injecting drugs were for being faster \u2018on the height\u2019 (42%) and cheaper (40%). Some factors related to the transition phase included: age of the first heroin use, year of the first heroin use, situation for migrating into Ha Noi, knowledge level, the kind of drug used for the first time. Young people began using heroin in the year 2000 had a quicker transition phase than those using heroin before 1997 (p< 0.01).

OBJECTIVES: The prevalence of diabetes mellitus is rapidly increasing in Vietnam, particularly among adults aged over 45 years. This study estimated trends in diabetes and prediabetes prevalence and determined risk factors in Vietnamese adults (over 45 years). METHODS: A cross-sectional study was conducted based on data from an annual diabetes screening program among people aged 45-69 years in an urban city in central Vietnam (Da Nang). Joinpoint regression analyses were performed to calculate the annual percentage change and ptrend-values. Multinomial logistic regression analysis was used to determine risk factors. RESULTS: In total, 3,765 men and 9,149 women were included in this analysis. The age-adjusted prevalence of diabetes and prediabetes in 2017 was 11.4% and 52.9%, respectively. The prevalence of diabetes was higher in men (15.1%) than in women (10.3%), but that of prediabetes was similar in both genders (53.4% vs. 52.8%). The prevalence of prediabetes significantly increased during the study period, whereas no upward or downward trend for diabetes was observed. The prevalence of obesity, abdominal obesity, hypertension, and dyslipidemia showed no obvious trend. Obesity, a high waist-to-hip ratio, hypertension, more severe abdominal obesity, and dyslipidemia were significantly associated with a higher risk of diabetes and prediabetes. CONCLUSIONS Diabetes and prediabetes were more prevalent among people aged over 45 years than in the general population. Da Nang has experienced a marked increase in the prevalence of prediabetes. These findings have significant implications regarding the need for nationwide public health interventions and management aiming at diabetes prevention and control.

Aims: To isolate and characterize the lactic acid bacteria (LAB) strains from the “mam chua ca ro” (sour fermented fish) in the South of Vietnam and investigate their potential anti-bacterial properties. Methodology and results: Four LAB strains (MCR1, MCR2, MCR3 and MCR4) were isolated from the "mam chua ca ro" product and their anti-bacterial activity was determined using the spot assay and the paper disc diffusion method. The isolated LABs can inhibit Escherichia coli ATCC 25922, Staphyloccocus aureus ATCC 25923 and Vibrio parahaemolyticus BV016 and produce bacteriocin to control the growth of E. coli ATCC 25922 and S. aureus ATCC 25923, except V. parahaemolyticus. MCR2 was chosen to sequence 16S rRNA of Pediococcus acidilactic. Conclusion, significance and impact of study On the basis of their prominent anti-pathogenic bacteria activity, LAB strains isolated from Vietnamese sour-fermented fish products were verified as prospective probiotics.

As authorities braced for the arrival of the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), infrastructure investments and government directives prompted action in central Viet Nam to establish capacity for genomic surveillance sequencing. From 17 November 2021 to 7 January 2022, the Pasteur Institute in Nha Trang sequenced 162 specimens from 98 150 confirmed SARS-CoV-2 cases in the region collected from 8 November to 31 December 2021. Of these, all 127 domestic cases were identified as the B.1.617.2 (Delta) variant, whereas 92% (32/35) of imported cases were identified as the B.1.1.529 (Omicron) variant, all among international flight passengers. Patients were successfully isolated, enabling health-care workers to prepare for additional cases. Most (78%) of the 32 Omicron cases were fully vaccinated, suggesting continued importance of public health and social measures to control the spread of new variants.
