Introduction: Hepatitis C is a dangerous disease and if left untreated can have serious consequences to the patients. While hepatitis C is difficult to treat, its vaccine is still unavailable. Previous studies have showed that there is a low rate of drug users having HCV tests. This means HCV infections does not have any great importance attached to it amongst the drug user group.\r\n', u'Objectives: To discover the status of HCV infection among drug users in Hanoi and to analyse the associated factors. \r\n', u'Subjects and methods: This crossover descriptive study was conducted in Hanoi. Research objects consisted of only men within the 16 - 25 years old age group, who used heroin from 09/2005 to 12/2006. These participants were interviewed and tested for HIV, HCV and HBV.\r\n', u'Results: HCV prevalence is 35.1 %. Especially, the research has indicated that 100% of HIV infected cases have also contracted HCV. This co - infectious status can be a challenge to subjects when they experience ARV treatment. The mean age of surveyed participants is 19. 83.6% of them have attended secondary school. 30.1 % have taken part in illegal earning activities. \r\n', u'Conclusion: HCV infection was discovered in the early drug injection stage. The proportion of HIV infection among injecting drug users is 28.24 times compared to the smoking drug users.\r\n', u'

Background: Mental retardation is a common pathological state in children, accounting for about 1 - 3%. Children with mental retardation should have a life of integrity and proper support. The discovery and assessment the children will help us to orient the education, assistance and early intervention for them at each location. Objectives: This study aimed at determining the prevalence of mental retardation (MR) among children in some quarters and communes of Hue city and the degrees of mental retardation in these children. Subjects and method: Screening by WHO questionnaire \u201cTen Question screen for disability\ufffd?and learning results (if possible) of children from 6 to under 16 years old in 5 quarters (urban) and 2 communes (rural) randomly selected in Hue. Diagnostics and evaluations are based on the criteria of ICD \ufffd?10. Results: The prevalence of MR in this study was 0.94% (95%CI = 0.82 \ufffd?1.07), 1.18% in rural area and 0.84% in urban area; 1.16% among boys and 0.70% among girls. Mild MR accounts for 62.67% moderate: 19.36%, severe: 11.52% and profound: 6.45%. Conclusion: The prevalence was statistically significant higher in rural area than in urban area and in boys than in girls. There were predominant percentages of severe and profound MR.

Objective: To determine the new M-superfamily conotoxins from molluscivorous snail Conus bandanus in Vietnam. Methods: Conus bandanus venom was fractionated and purified on HPLC system with an analytical reversed-phase C18 column in order to screen small conotoxins. The primary structure of peptide was analyzed by matrix-assisted laser desorption/ionization time of flight tandem mass spectrometry using collision-induced dissociation and confirmed by Edman's degradation method. Results: Five new conotoxins were biochemically characterized from the crude venom of the mollusk-hunting cone snail Conus bandanus, which were collected at Ke Ga reef of the Nha Trang Bay (Vietnam). Each conotoxin had 15 or 16 amino acid residues and shared the same characteristic cysteine framework V as -CC-C-C-CC-. They were termed as Bn3b, Bn3c, Bn3d, Bn3e and Bn3f following the conotoxins nomenclature. Conclusions: The conotoxins Bn3b, Bn3e, and Bn3f are categorized in the mini-M conotoxins of the M1 branch, while conotoxins Bn3c and Bn3d are categorized in the mini-M conotoxins of the M2 branch. The homological analysis reveals that these conotoxins could serve as promising probe compounds for voltage-gated sodium channels.

Background: Shigella-induced diarrhea has been considered a major health problem leading to high morbidity and mortality. This disease can lead to dire consequences; however, the true burden of the disease, including the costs and sequalae associated with shigellosis is not yet known. Objectives: (1) To describe the health seeking behavior and the way of payment of population when suffering Shigella; (2) To identify and analyze the direct household costs associated with the treatment of diarrhea due to Shigella. Subjects and method: 290 patients of all ages with positive Shigella diarrhea admitted to public health facilities in Nha Trang, Khanh Hoa province in the period from August 2002 to January 2004 were included in the study. The subjects were divided into three age groups, the first 0-5, second 5-18 and the last one was over 18 years old. Patients and their relatives were interviewed at three stages - day 7, day 14 and day 90 - to obtain all the required information. Results: 134 of 290 patients (47%) paid for using the other health care services before admission to the study\u2019s facilities. The average direct cost per episode for the patients at group aged 0-5 was 129,000 VND, group aged 6-18 was 59,267 VND and over 18 years old was 173,531 VND; it was 131.960 VND for three groups. Comparison with the average household expenditure for health care, it was higher in the poorer group and it was lower three times than the richest group. The average direct medical cost per episode was higher the average direct non-medical cost per episode for all groups. Conclusions: The average direct cost per episode of Shigellosis treatment was rather high especially the average direct cost for the treatment at the health facility. It was also high compared with the average expenditure for health per capita so that it becomes large economic burden for households.

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.
