Background: Forest malaria is one of the challenges faced by the Malaria Control Program in Vietnam. Objectives: (1). To evaluate the malaria prevalence among forest goers, (2). To study the efficacy of insecticide-treated hammock net (ITHNs) in malaria prevention for forest goers. Subject and method: The descriptive epidemiological intervention study on the effect of ITHNs in forest malaria control has been carried out in Ninh Thuan in 2005 \ufffd?2006. Results: Malaria prevalence among forest goers was very high: Clinical malaria: 15.5%, enlarged spleen: 7.0%, confirmed cases: 13.3% and asymptomactic cases: 74%. Age, sex, ethnic, low educated levels, low income, less use of mosquito-nets and poor house condition were considered as risk factors in malaria infection, especially for people who spent much time in the forest. ITHNs were effective in prevention of malaria infection, the malaria morbidity was decreased after 2 years of application (reduced from 31 % to 14% for prevalence, and from 274/1000 population to 161/1000 population for incidence), and the morbidity rate was lower than that in the group of people who did not use ITHNs. Conclusion: For the entomological survey, it is found that Anopheles density reduced in the group of people prevented by ITHNs. The residual of insecticide on the hammock net was decreased after 2 years utilization.\r\n', u'\r\n', u'\r\n', u'

Background: The vulnerability to contract malaria was researched among the Raglai ethnic minority population living in the mountainous areas of Ninh Thuan province, South-central Viet Nam, one of the areas with highest incidence rates in the country. Objective: To investigate the bed net use, risk perception of contracting malaria in Raglai ethnic minority. Subject and Method: The study used qualitative and quantitative method and was carried out in Ninh Thuan from 8/2005 to 8/2006. Result: Raglai exposure to malaria was related to farmers' forest activity and forest sleep which were directly related to the combination of sleeping and living in a government supported home in newly established villages along the road with a second home or reduced plot hut near fields in the forest to meet work requirements during the labor intensive malaria transmission and rainy season. In this context, access to health care, bed net use, risk perception of contracting malaria and health seeking behavior were researched. Conclusion: The results of the study do not only show the vulnerability of an impoverished ethnic minority population but as well the urgent need to better understand ethnic minorities' social context and culture to improve malaria control strategies.

Background: Coordinating between soldiers and people bring significant results in protecting healthy for soldiers and people in malaria epidemic area.\r\n', u'Objectives: To evaluate epidemic supervision and propose solutions protecting healthy for soldiers and people in malaria epidemic area.\r\n', u'Subjects and methods: A retrospective cross sectional study was carried out on two provinces Binh Phuoc and Dak Lak\r\n', u'Results: there was 4 main disease types were fever, tuberculosis, diarrhea and malaria. Malaria at investigated times still accounted high rate comparing with general fever rate. Malaria risk contained in people living or working in forest and mountain field; free emigrants; armed forces and border guard. These subjects needed to improve regularly protection from malaria. Communication of health education is one of important method to prevent and control malaria.\r\n', u'Conclusion: It is necessary to implement strong methods (such as providing insecticide treated bed nets, indoor residual spray) to prevent and control malaria. \r\n', u'

Surgical sperm retrieval (SSR) is currently one of the most common procedures in in vitro fertilization (IVF). However, a gap between the guidelines and routine clinical practice regarding antibiotic use in SSR, which might lead to antibiotic resistance, is a challenging problem worldwide. A cross-sectional survey was conducted from May 1, 2021, to July 15, 2021, to investigate antibiotic usage by medical professionals when performing SSR in IVF centers in Vietnam. The confidential questionnaire comprised 12 items, including characteristics of the study population, awareness of antimicrobial resistance, attitude toward prescribing antibiotics, and current practice of prescribing antibiotics when performing SSR. Surveys were completed by 30 of 45 registered IVF centers (66.7%). Among 67 physicians working at those centers, the age and work-experience years (mean ± standard deviation [s.d.]) were 38.6 ± 6.6 years and 11.2 ± 7.0 years, respectively. Over 60% of them held a degree in Obstetrics and Gynecology, and over four-fifths were men. Most respondents "often/very often/always" raised awareness of antimicrobial resistance to their patients (83.3%), but only half of them "often/occasionally" prescribed antibiotics to patients with SSR in cases where the prescription would be optional. About one-tenth of respondents followed the recommendation from the American Urological Association using "prophylaxis only" for SSR patients. For more invasive SSR, physicians tended to prescribe more complicated and sometimes inappropriate regimens. In conclusion, antibiotic usage in SSR was not always appropriate among IVF centers. Further studies may define specific recommendations for regimens, intervention strategies, and programs to promote appropriate antibiotic use for SSR patients among IVF specialists.

Background: Suicide continues to be a leading cause of death worldwide. Recently, more than 45,000 children in the age group of 10 to 19 years died by suicide, making it the second leading cause of death in the age group of 15 to 19, surpassed only by traffic accidents, tuberculosis, and fighting. Objective: To determine the prevalence of suicidal ideation among adolescents whose parents are separated/divorced; and to explore the factors associated with suicidal ideation and describe adverse experiences among adolescents. Methods: A cross-sectional descriptive study was conducted in 309 adolescents with separated/separated parents in Hue City. Data was collected through direct interviews using a structured questionnaire. Suicidal ideation was defined as the presence of thoughts or plans related to suicide within the last 12 months. Multivariate logistic regression was applied to identify factors associated with suicidal ideation in adolescents with separated/ separated parents. Results: The study found that 15.5% (95% CI:11.7 - 20.1) of adolescents with separated /separated parents reported experiencing suicidal thoughts, in which men accounted 8.4% (95% CI:5.6 – 11.2) and women accounted 7.1% (95% CI:4.5 - 10.6). Several factors were identified as increasing the risk of suicidal ideation, including alcohol use (OR = 3.24; 95% CI:1.42 - 7.42), hyperactivity/inattention (OR = 4.96; 95% CI:1.58 - 15.605), and a poor quality of family relationships (OR = 4.82; 95% CI:1.26 - 18.50). On the contrary, certain factors were found to reduce the risk, including being in the 14-15 age group of 14-15 (OR = 0.26; 95% CI:0.10 - 0.69) and participating in physical activity (OR = 0.44; 95% CI:0.21 – 0.94). Conclusions: The research highlights a significant percentage of adolescents with separated / divided parents who experience suicidal ideation. Therefore, it is imperative for families, schools, and society to develop comprehensive strategies to monitor and address various risky behaviours among students simultaneously.
