Introduction: In Vietnam, gastric cancer (GC) ranks 4th in incidence and 3rd in mortality among all cancers. Most of the new GC cases in Vietnam were diagnosed at an advanced stage. Data on early gastric cancer (EGC) in Vietnam is very limited. This study aimed to evaluate the prevalence, endoscopic and histopathological characteristics of EGC among Vietnamese patients.

Methods: This is a retrospective study conducted at the University Medical Center of Ho Chi Minh City, Vietnam from January 2014 to December 2019.  Electronic medical records of patients with EGC were reviewed to collect data regarding age, gender, endoscopic findings of EGC lesions (including location, size, and their type according to the Japanese classification of gastric carcinoma), and histopathological characteristics of these lesions based on the resected gastric specimens.

Results: Among 1666 patients with GC, there were 67 EGC cases, accounting for 4.0%. All of the patients diagnosed with EGC were older than 40 years. The detection rate of EGCs gradually increased during the study period. The EGC lesions were mostly located in the antrum-incisura angularis (73.1%) with a median diameter of 1.0 cm. Regarding macroscopic types, a majority of these lesions were classified as type 0-IIc (31.3%) and type 0-IIa+0-IIc (29.9%). The most common histological type of EGC was adenocarcinoma (82.1%) and poorly differentiated type (40.3%).

Conclusions: EGCs are mainly detected in individuals aged over 40 years. EGC lesions are commonly located in the antrum-incisura angularis and have characteristic features including the macroscopic and histological types.

Introduction: Major depressive disorder (MDD) presents a diverse clinical picture, especially with somatic symptoms, which can lead to negative impacts on the course and prognosis of the illness. This study aimed to (1) assess the prevalence of various somatic symptoms in MDD patients and (2) assess their association with demographic factors.

Methods: A total of 345 outpatients diagnosed with MDD according to DSM-5 criteria were enrolled in this cross-sectional study over 6 months. Participants completed a questionnaire that included clinical and demographic information as well as the PHQ-9.

Results: There were 99.7% of patients who had at least one somatic symptom. The common somatic symptoms were fatigue (89.9%), insomnia (87.8%), palpitations (77.7%), headache (69.6%) and dizziness (61.4%). Total PHQ-9 scores and total number of somatic symptoms were found to have a regression relationship with a regression coefficient of 0.14 (t = 6.001, p < 0.001). In multiple logistic regression analysis, female gender was found to be associated with dizziness (odd ratios [OR] = 2.54, 95% confidence interval [CI] 1.53-4.21, p < 0.01), headaches (OR = 1.94, 95% CI 1.16-3.32, p < 0.05), and bowel problems (OR = 0.59, 95% CI 0.37-0.96, p < 0.05); while headaches (OR = 1.73, 95% CI 1.05-2.85, p < 0.05), and stomach problems (OR = 0.56, 95% CI 0.36-0.88, p < 0.05) were associated with age 40 and below.

Conclusions: The study findings provide a resource for clinicians in mental health settings as well as primary care clinics in detecting inexplicable somatic symptoms associated with MDD.

Introduction: This study aimed to translate the 31-item Quality of Life in Epilepsy Inventory (QOLIE-31) into Vietnamese and validate the translation.

Methods: The inventory was translated through “forward – backward” translation, and culturally adapted for standardization. To ensure the reliability of the inventory, the internal consistency and the temporal consistency was determined. Clinical variables were tested for discriminant validity by comparing their scores.

Results: Cronbach’s alpha coefficient ranged from 0.91 to 0.57, with the lowest in the Overall quality of life subscale. Test-retest reliability showed high reproducibility with intra-class correlation coefficients ranging from 0.72 to 0.87 (p<0.001). The mean score of QOLIE-31 was 71.31. Further, the study used the statistical differences of QOLIE-31 scores in the drug-resistant group to show discriminant validity.

Conclusion: The Vietnamese QOLIE-31 is a reliable and valid instrument as proven by the statistical data and can be used to assess quality of life in people with epilepsy. 

Objective: Dengue is an infectious disease that causes a worldwide health and economic burden despite the efforts to eradicate the disease. From 2013 to 2015, dengue epidemic significantly increased from 33,626 to 50,205 cases in Vietnam. This study aims to determine the genotype variations of dengue virus (DENV) circulating in Southern Vietnam during 2014-2015.

Methods: C6/36 cells were infected with twenty-four strains of dengue virus isolated in 2014-2015 and kept frozen. The complete nucleotide sequence of dengue virus genomes was obtained by polymerase chain reaction (PCR). The genome was sequenced in the MiSeq system and analyzed by the basic local alignment search tool (BLAST) program. Data from GeneBank was used to create the phylogenetic trees.

Results: Among the 17 analyzed strains from 8 southern provinces, four (23.53%) were DENV-1, three (17.65%) were DENV-2, five (29.41%) were DENV-3, and five (29.41%) DENV-4 were isolated. Four DENV-1 isolates belong to Asia genotype. Three DENV-2 strains were concentrated in a subgroup of Asian 1 genotype. Five DENV-3 isolates were identified as belonged to Asian 2 genotype and five DENV-4 isolates were found as belong to Asia 1 genotype. There were no amino acid mutations and the transition capacity between the nucleotide among four types of DENV serotypes suggested that the probability of conversion from C to T was the highest conversion rate.

Conclusions: These DENV isolates were genetically close to other previous strains isolated from Vietnam and its neighboring countries, including Thailand, China, Cambodia, and Singapore, Brazil, Sri Lanka due to dynamic transmission. 

Introduction: Antibiotic resistance has been determined as a global threat. Inappropriate use of antibiotics is a crucial driver of the evolution of resistance.

Methods: A cross-sectional study was conducted aiming to describe the antibiotic usage among the elderly (60 years old and above) in Tan Loi commune, Dong Hy district, Thai Nguyen province, Vietnam in 2020. The questionnaire survey was submitted to 370 participants.

Results: More than half of the participants were female. The proportion of the elderly who bought antibiotics using a prescription was 39.2%. The participants normally bought the medicines the same as the previous (53.0%), medicine seller’s advice (44.9%), and relatives/friends’ advice (15.4%). More than half of the participants bought antibiotics themselves (57.8%). Local private pharmacies and health centers/hospitals were common locations for buying antibiotics, 63.8%, and 34.1% respectively. The percentage of the participants who stopped taking antibiotics when the symptoms are gone was 54.1%. More than 50.0% of the participants would change to more expensive antibiotics in case of symptoms are not released after using antibiotics. Some factors significantly associated with prescription usage were education levels, ethnic, obtained information related to antibiotic uses, others helping to buy the antibiotics.

Conclusions: The proportion of the elderly using antibiotics with a prescription was low. Majority of the participants bought antibiotics from the local private pharmacies. The main source of information to buy antibiotics was as the last time and medicine sellers. Some factors significantly associated with prescription use were education level, ethnicity, obtained information related to antibiotic uses, individuals who buy the medicines. Interventions are needed to improve knowledge and practice in buying antibiotics not only for the elderly but also for health service providers, private pharmacies in particular. 

Introduction: Body constitution (BC) plays an important role in preserving health and reducing risk of diseases depending on each person’s physical characteristics. Classification of BC is almost based on the Constitution in Chinese Medicine Questionnaire (CCMQ). In Vietnam, there is still no questionnaire survey to assess the BC. Therefore, this study aims to adapte and validate the Vietnamese version of CCMQ.

Methods: 2 phases of the study: the first phase constituted the translation with cross-cultural adaptation of CCQM into Vietnamese according to Guillemin et al; the second phase assessed the reliability and validity of the Vietnamese CCMQ version based on a cross-sectional study.

Results: Phase 1 formed the final Vietnamese CCMQ version in which face validity and content validity are incorporated. Seven traditional medicine practitioners confirmed the content validity (CVI: 57%–100%). The face validity of the scale is qualified. In phase 2, 455 participants aged 18 years old or older were enrolled in this study from 01/2021 – 06/2021 in Ho Chi Minh City. Regarding the criterion validity, the correlation coefficient between Vietnamese CCMQ and SF-36 was 0.67 for the Neutral type and -0.31 to -0.57 for the rest. The internal consistency varied from 0.70 to 0.83 measured by Cronbach’s alpha. The test-retest reliability varied from 0.63 to 0.90 for each of the 9 sub-scales and from 0.40 to 0.68 for each of the 60 questions.

Conclusions: The Vietnamese version of CCMQ has good reliability and validity, which provides a strong basis for future researches on BC of Vietnamese Traditional Medicine. 

Introduction: The rapid increase of infected cases and fatalities during the COVID-19 pandemic has created a huge health crisis to the world and Vietnam in particular. Health professionals were put under massive pressure in preventing pandemic. This study was conducted to assess the knowledge, attitude and practice (KAP) during the COVID-19 disease through an online survey as well as related infection control practices among pharmacy students in the University of Medicine and Pharmacy at Ho Chi Minh City (UMP).

Methods: The cross-sectional study was conducted based on the data obtained from an online questionnaire. Correlation analysis was performed using statistical tests and linear regression model for practice. The total study sample, chosen based on the inclusion and exclusion criteria was taken from pharmacy students in UMP during the study period.

Results: A scale of KAP towards COVID-19 was developed with 43 questions and received 1,089 responses. We acknowledged that the awareness and practice of these students were at a good level (with a mean score of 8.37±0.77 and 8.46±1.33, respectively) and the attitude was optimistic with a mean score of 6.22±0.68. Related factors to practice included gender (p=0.005), year of study (p=0.013); to knowledge included the time spent in university (p=0.040); to attitude included social distancing (p=0.024). Multivariable regression analysis showed that practice is related with male gender (β=-0.254; p=0.001), the first 3 school years (β = 0.173; p=0.020), knowledge score (β =0.154; p=0.003).

Conclusions: Based on a constructive scale, the study noted students' knowledge-attitude-practice towards COVID-19 at a good level. School year and knowledge scores positively affected practice scores, while male students had a negative effect.

Background: This study translated and culturally adapted the Comfort Behavior Scale (Comfort-B) into Vietnamese using a standard protocol guided by the World Health Organization.

Methods: The Comfort-B was translated into Vietnamese and then English back-translated by independent translators. These versions were reviewed and assessed by a Vietnamese expert’s panel and an English expert’s panel. Thirty-four nurses of the Nhi Dong 1 Hospital were invited to use the Vietnamese Comfort-B to assess pain while watching five videos recorded before, during and after wound dressing replacement. The eight characteristics of the Vietnamese Comfort-B were assessed by 34 nurses. Fifteen nurses agreed to do the second assessment two weeks from the first assessment. The content validity index was used to assess the relevance and clarity of all items and the whole scale. Agreements between raters were explored using Kappa statistics. Intraclass correlation coefficients (ICC) were used to assess intra-rater and inter-rater reliability. Multi-level linear regression was used to assess changes in the Vietnamese Comfort-B before, during and after wound dressing replacement between two assessments.

Results: The Vietnamese Comfort-B was accredited by the Vietnamese expert’s panel. The English-back translated version was approved by the English expert’s panel. The nurses agreed that the Vietnamese Comfort-B can be used in clinical practice and research. Kappas of all items were ≥0.96 indicating excellent agreement between raters. Alpha coefficients of two assessments were ≥0.97 indicating excellent internal consistency. All ICCs ≥ 0.79 indicated good intra-rater and inter-rater reliability.

Conclusions: The study suggested that the Vietnamese Comfort-B can be used for future studies assessing children’s pain in the local hospital context.

Introduction: Nursing handover is an important process in hospital care where information and responsibilities are transferred from one nurse to another to ensure continuity of care and safety of patients. However, evidence of the effectiveness of using standardized nursing handover approaches, particularly in resource-limited countries, is scarce. This study was conducted in order to evaluate the change in handover practice through the “I PASS the BATON” model in a university hospital in Vietnam and identify factors contributing to the effectiveness of this model.

Material and methods: We provided handover training for nurses in the Emergency Department using the “I PASS the BATON” model and evaluated their application right after the course and one month after the course.

Results: The consistency of the handover skill among participating nurses remained high one month after applying the model in the routine care at the hospital. Overall, the mean score achieved after training was high and remained unchanged after one month. However, significant and marginally significant improvement was found in some components one month after the course including the Action and Timing. In contrast, the Next component decreased over time. Evaluation of nurses’ perceptions about the model were assessed using the Health Belief Model which revealed that perceived susceptibility and seriousness were at the moderate level and significantly decreased after one month. In contrast, perceived benefits and barriers were at a high level and remained unchanged after one month.

Conclusions: The "I PASS the BATON" model was effective in improving nurses’ handover skills and practices.

Background: In Vietnam, surgery or aspiration is preferred to treat thyroid cysts however each of them still have limitations. Purposes of this study were to evaluate the efficacy and safety of ethanol ablation in treating thyroid cysts and determine factors that predict the outcome of treatment.

Methods: This prospective study was approved by the Ethics Committee of the Institutional Review Board of Family hospital and written informed consent for procedures was obtained. From May 2018 to March 2019, 23 patients who underwent treatment for thyroid cysts by EA were enrolled in this study and were followed up for 1 month at Family hospital. The primary endpoint was efficient after one month as the volume reduction ratio was ≥ 50%. Secondary endpoints were improvements in symptoms, cosmetic scores, and safety. Multiple logistic regression analysis was used.

Results: In the finding, from May 2018 to March 2019, only 17 patients who matched inclusion criteria were included in the analyst, including 7 purely thyroid cysts, and 10 predominantly cystic nodules. Mean volume decreased significantly from 5.21 ± 3.37 ml to 2.35 ± 2.52 ml in corresponding to 52.87% of volume reduction with p < 0.05. Ethanol ablation (EA) success rate was 52.90% after 1 month. Symptoms and cosmetic scores were improved significantly. The thyroid function was constant. No adverse events occurred. Purely thyroid cyst was a predictive factor contributing to the success of EA.

Conclusion: EA seems likely to be a safe and an efficient therapy for patients who had purely or predominantly cystic thyroid nodules.

Current pathophysiologic knowledge of achalasia suggests the important involvement of genetic predisposition. However, familial achalasia is very rare and most of the case reports in literature have shown an autosomal recessive pattern of inherence. We hereby report a case of familial achalasia with autosomal dominant pattern of inherence affecting ten members in three generations of a Vietnamese family.

Background: The study aimed to culturally adapt and validate Neonatal Infant Pain Scale (NIPS) for use in Vietnamese settings.

Methods: The original NIPS was translated into Vietnamese using a standard protocol. Registered nurses of Neonatal Intensive Care Unit (NICU), Tien Giang General Hospital, Vietnam used the Vietnamese NIPS for assessing neonatal pain and then provided feedback on acceptability of the scale. Five registered nurses of NICU were randomly selected and used NIPS for assessing neonatal pain while watching thirty videos at two times, two weeks apart from each other. Pulse rates per minute and oxygen saturation (SpO₂) were also recorded for validity evaluation. Intraclass correlation coefficients (ICC) with two-way random effects were applied to assess intra-rater and inter-rater reliability. Multilevel linear regression was applied to assess the association between NIPS score with pulse rates and SpO₂ adjusting for raters, three periods and two assessments.

Results: The Vietnamese NIPS was accepted and valued by nurses at the NICU. ICCs between the first and second assessments were from 0.53 to 1.00 for five raters before, during and after clinical procedures showing moderate to excellent intra-rater reliability. ICCs among five raters were moderate to good before and after, but poor (ICC<0.4) during clinical procedures. NIPS score was not associated with SpO₂, but with pulse rates per minute.

Conclusions: The preliminary results showed that the Vietnamese version of NIPS is reliable and should be used. However, it is recommended that further research should be conducted to confirm its reliability and validity.

Staphylococcus aureus (S. aureus) has long been recognized as an important human pathogen causing many severe diseases. It is also a part of human normal flora with its ecological niche in the human anterior nares. This study focused on screening S. aureus nasal carriage in community and its relationship to human physiological and pathological factors which have not been studied in Vietnam previously. Two hundred and five volunteers in Ho Chi Minh City from 18 to 35 and over 59 years old both male and female participated in the study. Result showed that the prevalence of S. aureus nasal carriage in southern Vietnamese community was relatively low, only 11.2% (23/205), much lower than that in other international reports on human S. aureus. In addition, nasal carriage of the older age group (> 59 years old, 13.7%) was higher than that of younger age (18-35 years old, 10.4%). Other potential risk factors such as gender, career, height, weight, history of antibiotic usage, daily nasal wash, use of nasal medication sprays, acne problems, smoking and nasal problems showed no significant impact on S. aureus carriage. The obtained S. aureus nasal isolates were all sensitive to vancomycin. Lincomycin and tetracycline had low resistance rate with 4.3 % and 17.4 %, respectively. However, the isolates showed particularly high rate of multidrug resistance (54.2%) In summary, our data provided researchers an overview on S. aureus nasal carriage and antibiotic susceptibility profile of the community- isolated S. aureus in Vietnam. This would serve as valuable information on assessing risk of community-acquired S. aureus infections.

Poor indoor air quality is one of the most important factor causing occupational health problems such as sick building syndrome (SBS). Most previous research on risk factors of SBS is evaluated in the office or school environments rather than in the hospital. The aim of this study is to investigate the prevalence of SBS and its related effect on hospital workers in poorly-ventilated and confined working environments through a set of the questionnaires completed from March to June of 2017. The relationship between SBS-Related symptoms, individual characteristics, work environment and conditions were analyzed using Poisson regression. The prevalence of sick building syndrome was 70.1%. The most common symptoms reported by hospital workers include fatigue, headache, and feeling heavy-headed. There was a significant relationship between the prevalence of syndrome and sex, overload of work, atopy as well as varying room temperature.
