1.Evaluation of knowledge, attitude and practice in vaccination against measles of mothers at some communes in Hue city
Journal of Preventive Medicine 2000;10(3):56-61
An interviewed survey on 147 mothers who have small children was carried out in some communes in Hue city to evaluate their knowledge, attitude and practice in vaccineation against measles. The results showed that most of the interviewed mothers (> 87%) had good knowledge about the severity of measles infection, the susceptibility of their children with measles virus and transmission of this disease. The mother’s acceptance to vaccineation against measles is good; this implies the efficiency of the vaccination program.

Malaria situation in Lao Cai was stable during 4 first months of 2008. Number of malaria patients has decreased by 39.88% so that the rate of malaria patients/population was reduced by 39.28% compared to the same period of the last year. No malaria parasites were found. The malaria prevalence was reduced in all districts compared to that of the same period of the last year. All the former malaria foci were stable with no new malaria patients found. The survey, however, revealed some weak points in the malaria surveillance network. Blood slides were not taken or taken in inconsiderable number in many communes; blood films were too small of slides were labeled over the blood film. Ten of fifty microscope points (20%) over the province had stopped working due to many reasons: movement of the staff, on training, birth leaves and so on. Forty microscope points were checked and ranked. Only 15 microscope points were ranked "good" (37.5%) as found to regularly work. These points were located mainly at hospitals, inter-communal clinics. Twelve others (12%) were ranked" fair" and 3 points (7.5%) were "weak". Many commune health centers did not regularly report monthly malaria data, or reported insufficient and wrong information causing incorrect data of the upper levels.

Journal of Preventive Medicine and Public Health 2024;57(3):279-287
Objectives:
This study validated the Vietnamese version of the Disaster Adaptation and Resilience Scale (DARS) for use in vulnerable communities in Vietnam.
Methods:
This was a cross-sectional study involving 595 adults from 2 identified communities. The original DARS assessment tool was translated, and the validity and reliability of the Vietnamese version of DARS (V-DARS) were assessed. The internal consistency of the overall scale and its subscales was evaluated using Cronbach’s alpha and McDonald’s omega reliability coefficients. Confirmatory factor analysis (CFA) was employed to evaluate its construct validity, building upon the factor structure identified in exploratory factor analysis (EFA). Construct validity was assessed based on convergent and discriminant validity.
Results:
Following the established criteria for EFA, 8 items were removed, resulting in a refined V-DARS structure comprising 35 items distributed across 5 distinct factors. Both alpha and omega reliability coefficients indicated strong internal consistency for the overall scale (α=0.963, ω=0.963) and for each of the 5 sub-scales (all>0.80). The CFA model also retained the 5-factor structure with 35 items. The model fit indices showed acceptable values (RMSEA: 0.072; CFI: 0.912; TLI: 0.904; chi-square test: <0.01). Additionally, the convergent and discriminant validity of the V-DARS were deemed appropriate and satisfactory for explaining the measurement structure.
Conclusions
Our findings suggest that the V-DARS is a valid and reliable scale for use within vulnerable communities in Vietnam to assess adaptive responses to natural disasters. It may also be considered for use in other populations.

The foundations of nuclear medicine in Vietnam were established from 1970. Until now, after 48 years of development, in Vietnam, we have some basic equipment including 31 SPECT, 4 SPECT/CT machines, 11 PET/CT scanners, five cyclotrons, and one nuclear reactor.Many nuclearmedicine techniques in diagnosis and treatment have been routinely performed at provincial and central level health facilities such as tumor scintigraphy, thyroid scintigraphy, bone scintigraphy, kidney scintigraphy, cardiac scintigraphy, and radio-isotope therapy with I-131 and P-32. Selective internal radiation therapy with Y-90 microsphere and I-125 radioactive seed implantation has been also successfully applied in some big hospitals. However, there are still many difficulties for Vietnam as the lack of new widely used radioisotopes such as Ga-67, Cu-64, Samarium-153, and Lutetium-177 and the lack of nuclear medicine specialists. In the future, we are putting our efforts on the applications of new isotopes in diagnosis and treatment of cancers (theranostic) like Ga-68-DOTATATE, Lutetium-177-DOTATATE, Ga-68-PSMA, and Lutetium-177-PSMA, equipping modern nuclear medicine diagnostic tools, strengthening the human resources training in nuclear medicine. At the same time, we are trying our best to strengthen the cooperation with international nuclear medicine societies in over the world.

Background: This study was conducted on 93 volunteers with type 2 diabetes to investigate the ability of acetylated wheat starch cake containing 32.1% resistant starch to control postprandial blood glucose levels. Material and methods: The study was designed using a crossover, double-blind trial method. During each testing day, after a minimum of 12 hours of overnight fasting, each participant consumed two identical cakes containing either 80 g of acetylated wheat starch or 80 g natural wheat starch with 330ml of water within 15 minutes. Blood glucose levels were measured at baseline, 60 mins (G1), and 120 mins (G2) after ingestion. The predictive value of factors that contribute to the ability of resistant starch to control postprandial blood glucose was determined by the area under the receiver operating characteristic (ROC) curve based on the combined effect of the cake weight-to-BMI ratio (g/m²BMI) and HbA1c. Results: 60 mins and 120 mins postprandial capillary glucose levels after consuming acetylated wheat starch cake (10.4 ± 1.2 và 9.2 ± 1.2 mmol/L, respectively) were significantly lower compared with natural wheat starch cake (13.3 ± 1.8 và 11.2 ± 1.8 mmol/L, respectively) (p < 0.05). For good control of postprandial blood glucose levels, a maximum of 80 g of acetylated wheat starch can be used per serving for patients with type 2 diabetes with HbA1c ≤ 7.25 without blood glucose-lowering medication is required. Conclusion: acetylated wheat starch has better ontroled of postprandial blood glucose compared with natural wheat starch in patients with type 2 diabetes. This is very suitable in the processing of diets including resistant starch for patients with type 2 diabetes for the purpose of both supporting treatment and improving quality of life.

Journal of Preventive Medicine and Public Health 2023;56(4):319-326
Objectives:
The coronavirus disease 2019 (COVID-19) pandemic has increased the workload of healthcare workers (HCWs), impacting their health. This study aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and identify factors associated with poor sleep among HCWs in Vietnam during the COVID-19 pandemic.
Methods:
In this cross-sectional study, 1000 frontline HCWs were recruited from various healthcare facilities in Vietnam between October 2021 and November 2021. Data were collected using a 3-part self-administered questionnaire, which covered demographics, sleep quality, and factors related to poor sleep. Poor sleep quality was defined as a total PSQI score of 5 or higher.
Results:
Participants’ mean age was 33.20±6.81 years (range, 20.0-61.0), and 63.0% were women. The median work experience was 8.54±6.30 years. Approximately 6.3% had chronic comorbidities, such as hypertension and diabetes mellitus. About 59.5% were directly responsible for patient care and treatment, while 7.1% worked in tracing and sampling. A total of 73.8% reported poor sleep quality. Multivariate logistic regression revealed significant associations between poor sleep quality and the presence of chronic comorbidities (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.17 to 5.24), being a frontline HCW directly involved in patient care and treatment (OR, 1.59; 95% CI, 1.16 to 2.16), increased working hours (OR, 1.84; 95% CI,1.37 to 2.48), and a higher frequency of encountering critically ill and dying patients (OR, 1.42; 95% CI, 1.03 to 1.95).
Conclusions
The high prevalence of poor sleep among HCWs in Vietnam during the COVID-19 pandemic was similar to that in other countries. Working conditions should be adjusted to improve sleep quality among this population.

OBJECTIVETo compare the prevalence of Helicobacter pylori (Hp) infection in children of Zhuang and Mulan ethnic groups, Guangxi Luocheng county, China and in children of Jing ethnic group, Central Vietnam and to analyze the association of HLA-DQA1 alleles of these ethnic groups' children with Hp infection.
METHODSSerodiagnosis by determining Hp antibody with ELISA and determination of serum CagA, VacA and urease antibodies by immunoblotting were performed for 54 Zhuang, 76 Mulan and 109 Jing children. Polymerase chain reaction-single strand polymorphism (PCR-SSP) technique was applied to determine the polymorphism of the HLA-DQA1 locus of these children and then the association of HLA-DQA1 alleles of these minority children with Hp infection was analyzed by SAS software.
RESULTSThe prevalence of Hp infection were 39% in Vietnamese Jing nationality, which was significantly lower than that in children of Guangxi Luocheng county (65% in Zhuang nationality and 58% in Mulan nationality) (P < 0.01). The distribution of HLA-DQA1 locus was not significantly different among the 3 groups. The frequency of HLA-DQA1 * 0104 allele was significantly higher in children with Hp infection than in children without Hp infection in each of the 3 groups (P < 0.01).
CONCLUSIONThe results indicated that the prevalence of Hp infection in Zhuang and Mulan minority ethnic groups in Guangxi, China was higher than that in Vietnamese Jing ethnic group children. HLA-DQA1 * 0104 allele may be associated with susceptibility to Hp infection.

Journal of Preventive Medicine and Public Health 2024;57(4):407-419
Objectives:
This study was conducted to measure financial toxicity (FT) among patients with cancer in Vietnam using the COmprehensive Score for financial Toxicity (COST) and to describe the cost management strategies employed by these patients.
Methods:
This comprehensive cross-sectional study enrolled 634 patients from 2 specialized oncology hospitals in Vietnam. Using COST cut-off scores, FT was classified as none/mild (≥26), moderate (14-25), or severe (≤13). Cost management strategies, or coping mechanisms, were classified into 4 groups: lifestyle changes, financial resource strategies, treatment modifications, and support seeking.
Results:
The prevalence of FT was 91.8%, with 51.7% of participants demonstrating severe and 40.1% exhibiting moderate FT. Severe FT was significantly associated with female, low education level, unstable employment, low household economic status, and advanced cancer stage. The most common coping strategies were as follows: among lifestyle changes, reducing spending on basic items and leisure activities (78.7%) and cutting back on essential household expenses (66.4%); among financial resource strategies, borrowing money from relatives or friends (49.1%) and withdrawing funds from retirement or savings accounts (34.1%); within treatment modifications, switching treatment facilities or doctors due to cost concerns (9.3%); and within support seeking, obtaining help from welfare or community organizations (18.8%). All strategies were significantly more likely to be used by patients with severe FT.
Conclusions
FT was highly prevalent among patients with cancer. Most patients relied on lifestyle adjustments and coping strategies, underscoring the need for improved financial support systems to alleviate the economic burden associated with cancer care.
