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.

Endophytic fungi are promising sources for the production of podophyllotoxin-an important anticancer compound, replacing depleted medical plants. In this study, the endophytes associated with Dysosma difformis-an ethnomedicinal plant species were isolated to explore novel sources of podophyllotoxin. Fifty-three endophytic fungi were isolated and identified by morphological observation and ITS-based rDNA sequencing, assigning them to 27 genera in 3 divisions. Fusarium was found the most prevalent genus with a colonization frequency of 11.11%, followed by Trametes (9.26%) and Penicillium (7.41%). Phylogenetic trees were constructed for the endophytic fungi community in two collection sites, Ha Giang and Lai Chau, revealing the adaptation of the species to the specific tissues and habitats. Cytotoxic activity of endophytic fungal extracts was investigated on cancer cell lines such as SK-LU-1, HL-60, and HepG2, demonstrating strong anti-cancer activity of six isolates belonging to Penicillium, Trametes, Purpureocillium, Aspergillus, and Ganoderma with IC 50 value of lower than 10 10 µg/mL. The presence of podophyllotoxin was indicated in Penicillium, Trametes, Aspergillus and for the first time in Purpureocillium and Ganoderma via high-performance liquid chromatography, which implied them as a potential source of this anticancer compound.

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.

Background: Phu Cat district, Binh Dinh province is one of the areas contaminated with Agent Orange in Wartime and now up to it still continues to affect the environmental life and health of people living there. Objectives: Investigate the factual status of mortality rate from 2002 to 2006 in Phu Cat district, Binh Dinh province and determine the burden of mortality based on the number of Years of Lost Life (YLLs). Subject and methods: A retrospective study was conducted on all deaths from January 1, 2002 to December 31, 2006 in Phu Cat population. Burden of mortality was analyzed using the WHO standard method. The dead cases were causal diagnosed by Verbal Autopsy tools and update information for mortality rate. Results: Mortality rates were 3.1%o (2002), 3.3%o (2003), 4.08%o (2004) and 2.67% (2005). YLLs from 2002 to 2006 in order are: 55.87%, 57.98%, 73.82%, 48.74% and 49.01%, respectively. The number of mortality in men was higher than women and had a tendency to increase from 2002 to 2004, to decrease during 2005 and 2006. YLLs in group of ages 0-4 was highest in 2004 (150.76%o), followed by 2002 (126.28%o) and was lowest in 2005 (39.72%o). YLLs in groups of ages >60 was high, especially in non-communicable disease. Conclusions: Mortality model from 2002 to 2006 in Phu Cat district, Binh Dinh province was appropriate for the national mortality model. According to YLLs, the burden of mortality was determined as the general burden of mortality from 2002 to 2006 and burden of mortality followed disease groups: communicable disease, nutrition disease and pregnancy; non-communicable disease; poisoned and accident related diseases.

Background: Recently, microplate almar blue assay has been used commonly in detecting gen related to tuberculosis drug resistance, which provides results after 5-7 days with lower cost compared to traditional methods. Objective: To evaluate the application of microplate almar blue assay for rapid detection of drug resistance of M. tuberculosis strains. Subject and Method: A microplate-based assay which uses Alamar blue reagent - an oxidation reduction dye (MABA), was used for the determination of the anti-tuberculosis drug (isoniazid-INH, rifampicine-RIF, streptomycine-STR and ethabuton=EMB) resistance of 96 M. tuberculosis strains isolated from Vietnamese patients in comparison to those obtained by conversional method. Result: MABA showed to have high sensitivity and specificity in testing the sensitivity to individual anti-tuberculosis drugs (from 82.4% for STR to 93.3% for - INH and from 82.5% for EMB to 98.4% for STR; respectively), as well as for the multi-drug resistant M.tuberculosis (86.4% of sensitivity), highly correlated with the result determined by proportion method. Conclusion: MABA reveals the advantage in shortening test time, in simple performance and lower cost compared with the conversional culture based methods.

Background: Acute Respiratory Infection (ARI) is a common disease in developing countries. Morbidity and mortality of ARI are high, especially among children under 15 years old. Objectives: To describe socio-graphic factors, seasonal patterns, risky areas and determine the morbidity and mortality rates of acute respiratory infections in Thai Binh province. Subjects and method: This retrospective study reviewed the medical records of 4,585 hospital admitted patients who were diagnosed with ARI including upper and lower respiratory infections such as sore throat, pharyngitis, bronchitis, pneumonia and bronchitis-pneumonia at 8 district hospitals and 1 provincial hospital in Thai Binh province during 2002-2005. The selected medical records were based on the available check list and two standard screening tests. Results:Morbidity and mortality of ARI in Thai Binh province were 61.6 and 0.52, respectively. ARI mainly occurred among children under 5 years old, of which the highest mortality was among those under 12 months of age. Male children were at higher risk of acquiring ARI, but less prone to death than female. Occupation did not significantly associate with the risk of ARI. The morbidity increased sharply during inter-season, e.g. March and October. Thai Binh city, Kien Xuong and Tien Hai district were reported with the highest morbidity in accompany of the high mortality as consequences. Conclusion: The prevention and control methods were recommended to annually focus on the male children aged less than 5 years old during March and October in Thai Binh city, Kien Xuong and Tien Hai district.

Background: Situation of extremity injury caused by traffic accidents and occupational accidents are increasing in Vietnam. Therefore, the prevention and fight against these accidents are one of the key objectives to reduce the burden on the families of victims as well as for society. Objectives: To outline situation of extremity injury patients caused by traffic accident, treated in Viet Duc hospital from 2000-2004. Subjects and method: A retrospective study was conducted on 19.845 patients (14.562 males, 5.283 females, aged from 1-97 years old). The subjects were divided into 3 main groups: alone upper extremity injury, alone lower extremity injury and multiple fractures. Results: Extremity injury was common seen in people of working age (78.1%), men more than women (2.76/1 ratio), left foot more than right foot and it was common been in multiple fracture situation due to complex mechanisms of injury (50.3%), alone extremity injury (49.7%). The lower extremity injury was more common seen than upper extremity injury. Open fracture injury (27.3%), in which open fractures in lower extremity were more common seen. Open fractures in both 2 leg bones was the most common seen, accounted for 57.4% among total of open fractures. Amputation accounted for 8.3% among all case of open fractures and 2.3% among all case of extremity injuries. Conclusion: Extremity injury (lower extremity and upper extremity) caused by traffic accidents is common seen. The average, there are 3 emergency surgeries due to open fracture injury were performed daily in Viet Duc hospital per a total of about 11 traumatic emergency surgeries.

Background: Open heart surgery with cardiopulmonary bypass (CPB) causes haemostatic abnormalities which result in postoperative excessive bleeding. Objectives: To investigate haemostatic disorders before - after CPB and postoperative bleeding. Subjects and methods: Sixty congenital cardiac patients with and without cyanosis were recruited consecutively. Hematology and coagulation tests were done 1 day before operation, 15 minutes after protamine administration, 2 and 6 hours after the operation in the intensive care unit (lCU). Mediastinal chest tube drainage (MCTO) was measured for the first 6h in the ICU. Results: Significant differences between 2 groups could be found for red blood cells, hemoglobin, hematocrit, fibrinogen, D-dimer, fibrinogen degradation products (FOP), von Kaulla and platelet aggregation to epinephrine before operation (p < 0.05). There were not significant differences in platelets, PT, APTT, platelet aggregation to adenosine diphosphate (AOP) in the acyanotic and cyanotic patients (p > 0.05). Most hematology parameters were decreased significantly and hemostasis measurements were prolonged after operation in both groups (p < 0.05). There was also the significant difference in MCTO between 2 groups (p < 0.05). Conclusion: Coagulation, hemostasis and fibrinolysis disorders; thrombocytopenia and acquired transient platelet dysfunction may be responsible for bleeding complications after CBP \r\n', u'\r\n', u'
