Background: Fragile X Syndrome (FXS) is the most common cause of inherited mental retardation. The absence of Fragile X Mental Retardation (FMRP) in Fragile X syndrome changes other proteins. Objective: To detect changes of glycoprotein in human serum of Fragile X syndrome. Subject and methods: Affinity chromatography with lectin concanavalin A (ConA) used to receive glycoprotein. The collected glycoprotein was then separated using 2-D electrophoresis. The protein spots were further excised, trypsin digested, and analyzed by nano LC couple with ESI-MS/MS and identified by MASCOT v1.8 software. Results and conclusion: 5 glycoproteins showed the different expression levels in the serum of Fragile X syndrome. Haptoglobin, Ig-J were increased and ceruloplasmin, transferring, Ig kappa were decreased. Using affinity chromatography with lectin concanavalin A (ConA), glycoprotein was received and divided on 2 ways electrokinetic chromatography. The mixture protein was identified with a reliability of 99.5% by 2 ways liquid chromatography combined with continuous spectrum mass.

BACKGROUND: In Vietnam, we observed a high incidence of carbamazepine (CBZ)-induced severe cutaneous adverse drug reactions (SCARs)-Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), and drug-induced hypersensitivity rash with eosinophilia and systemic symptoms (DRESS). In other Asian countries, HLA-B*1502 is an established risk factor for SCARs. OBJECTIVE: The aim of our study was to determine the frequency of HLA-B*1502 in SCARs patients at a large University Medical Center in Hanoi, Vietnam. METHODS: Thirty-eight cases of SCARs caused by CBZ and 25 patients with epilepsy tolerating CBZ were enrolled in a case-controlled study. Clinical manifestations and laboratory findings were recorded for each subject. Genomic DNA was isolated using the QIAamp DNA purification system. The combination of polymerase chain reaction and sequence specific oligonucleotide probes with the Luminex 100×MAP flow cytometry dual laser system was then used to quantitate fluorescently labelled oligonucleotides attached to colour-coded microbeads. RESULTS: Cases comprised 20 SJS (52.6%), 7 TEN (18.4%), 8 overlap syndrome (21.1%), and 3 DRESS patients (7.9%). A strong association between HLA B*1502 and bullous skin reactions such as SJS/TEN and overlap was confirmed with an odds ratio (OR) of 33.78 (95% confidence interval [CI], 7.55-151.03), p < 0.0001, Sensitivity 91.4%, Specificity 76.0%, positive predictive value 84.2%, and negative predictive value 86.4%. We did not, however, observe any correlation between the presence of this allele and CBZ-induced nonbullous skin reactions (DRESS) (OR, 6.33; 95% CI, 0.48-82.74; p = 0.1592). CONCLUSION: Our results indicate the presence of HLA-B*1502 in Vietnamese is a pharmacogenetic risk factor for developing CBZ-induced SJS/TEN.

Annals of Coloproctology 2022;38(4):297-300
Purpose:
Laparoscopic surgery is considered a promising approach for Hartmann reversal but is also a complicated major surgical procedure. We conducted a retrospective analysis at a city hospital in Vietnam to evaluate the treatment technique and outcomes of laparoscopic Hartmann reversal (LHR).
Methods:
A colorectal surgery database in 5 years between 2015 and 2019 (1,175 cases in total) was retrieved to collect 35 consecutive patients undergoing LHR.
Results:
The patients had a median age of 61 years old. The median operative time was 185 minutes. All the procedures were first attempted laparoscopically with a conversion rate of 20.0% (7 of 35 cases). There was no intraoperative complication. Postoperative mortality and morbidity were 0 and 11.4% (2 medical, 1 deep surgical site infection, and 1 anastomotic leak required reoperation) respectively. The median time to first bowel activity was 2.8 days and median length of hospital stay was 8 days.
Conclusion
When performed by skilled surgeons, LHR is a feasible and safe operation with acceptable morbidity rate.

Background: Periostin (PN) concentration increases in the blood of patients after acute myocardial infarction (AMI) and affects the process of cardiac remodelling leading to myocardial fibrosis. This study aimed to evaluate the correlation between serum PN levels with cardiac function and short-term prognosis (after 3 months of AMI) in patients with non-ST-elevation AMI. Methods: Case-control study, 3-month follow-up. 35 patients with AMI and 37 healthy people were chosen as the control group. In the group of patients, serum PN was obtained from day 5 - 7 of the disease. The correlation between PN and TIMI, GRACE scores, body mass index (BMI), laboratory findings, and 3-month post-MI data including pro B-type natriuretic peptide (pro-BNP) and echocardiographic parameters. Results: Serum PN levels increased significantly when patients had AMI, negatively correlated with ejection fraction (EF) (r = - 0.462, p = 0.005), positively correlated with left ventricular end-diastolic diameter (LVDd) (r = 0.413, p = 0.014). Conclusions: AMI increases serum PN levels, and PN can be used to predict cardiac function 3 months after MI in patients with non-ST elevation AMI.

Background:
Hand, foot and mouth disease (HFMD) is a public health problem in Viet Nam, and studies have reported seasonal fluctuation in the occurrence of HFMD. This study sought to describe the occurrence of HFMD and its associated meteorological factors in Dak Lak province, Viet Nam.
Methods:
Monthly data on HFMD cases were collected from all commune health stations in Dak Lak province from 2012 through 2013. An HFMD case was defined as a brief febrile illness accompanied by a typical skin rash with or without mouth ulcers. Average temperature, maximum temperature, minimum temperature, humidity, rainfall, evaporation, sunshine duration and wind speed were recorded monthly at five local meteorological stations throughout Dak Lak.Data were aggregated at the district level, and the association between these meteorological factors and HFMD cases were examined by Poisson regression.
Results:
In 2012 through 2013, there were 7128 HFMD patients in Dak Lak. The number of HFMD cases increased during the rainy season. An increased risk of HFMD was associated with higher average temperature (risk ratio and 95% confidence interval: 1.06; 1.03–1.08 per 1 °C increase), higher rainfall (1.19; 1.14–1.24 per 200 mm increase) and longer sunshine duration (1.14; 1.07–1.22 per 60 hours increase). The risk of HFMD was inversely associated with wind speed (0.77; 0.73–0.81 per 1 m/s increase).
Conclusion
This study suggests that there is a significant association between HFMD occurrence and climate. Temperature, rainfall, wind speed and sunshine duration could be used as meteorological predictors of HFMD occurrence in Viet Nam’s Central Highlands region. Intensified surveillance for HFMD during the rainy season is recommended.

The COVID-19 pandemic outbreak and subsequent lockdowns impacted the mental health of numerous sociodemographic groups globally. This crisis can produce stress, overwhelm, and powerful emotions in susceptible people, especially older persons. Our study examined the relationship between well-being and fear of COVID-19 among older persons residing in Ho Chi Minh City, Vietnam, during the pandemic. A sociodemographic survey was undertaken. Two scales are used for a month of the COVID-19 outbreak: the Mental Health Continuum Short Form (MHC-SF) and the Fear of COVID-19 Scale (FCV-19S). We surveyed 158 senior citizens in Ho Chi Minh City between February and April 2021. There was no lockdown in Ho Chi Minh before the fourth wave of infection. Despite this, citizens have maintained high compliance with coronavirus prophylaxis. Sociodemographic data were described using descriptive statistics. A one-way MANOVA assessed the financial impact on older individuals' well-being. The Pearson correlation was employed to find the link between happiness and COVID-19 dread. During the COVID-19 pandemic, older persons who received various monthly allowances had statistically significant emotional and psychological well-being differences. There was no association between well-being and COVID-19 dread. The COVID-19 epidemic has disproportionately affected vulnerable groups. Older individuals are a risk population that requires material and mental care.

Malaysian Journal of Nutrition 2022;28(No.3):315-325
Introduction: Many people are currently interested in improving and maintaining
their health status by changing their dietary habits, like eating more natural foods;
thus sprout products are becoming increasingly popular. In this context, sprouted
brown rice grains are an excellent example of functional food, because besides their
nutritive value, they also lower the risk of various diseases and/or exert healthpromoting effects. In this paper, we focused on the bioactive compound γ-aminobutyric
acid (GABA) in germinated brown rice. GABA is known as an important amino acid
that can help reduce hypertension and inhibit cancer cells development. Methods:
We investigated the hydration characteristics of brown rice by drying them in a
moisture analyser at 130°C until reaching a constant weight. The effects of soaking
(duration and pH of soaking solution), as well as incubation conditions (temperature
and time) on GABA biosynthesis in MangBuk brown rice of Vietnam were measured.
Quantification of GABA was measured using a spectrophotometer. Results: GABA
content in MangBuk type 1 brown rice was higher than in type 2. GABA content
reached its highest value at 691.88 µg/g for type 1 rice and 596.48 µg/g for type 2
rice when MangBuk brown rice was soaked in a pH 7 water at 30°C for 12 hours, and
then incubated at 35°C for 30 hours in aerobic condition. Conclusion: Germination
conditions modified the content of biologically active compounds in MangBuk soft
and hard rice varieties. GABA was synthesised during germination based on three
factors, namely time of incubation, temperature of incubation, and pH of solution.

Introduction:
When Viet Nam launched the Expanded Programme on Immunization in 1981, it covered six vaccines, including measles. Subsequently, Viet Nam experienced a marked reduction in measles infections. A nationwide measles epidemic occurred in April 2014 and an investigation found that 86% of affected children aged 9 months to 10 years were not fully vaccinated; therefore, understanding the reasons for not vaccinating could improve vaccination coverage.
Methods:
We performed a cross-sectional study to determine vaccination coverage and reasons for non-vaccination among children aged 9 months to 10 years in six districts in Ho Chi Minh City with the highest number of measles cases in 2014. Measles vaccination status of the youngest child in each household was determined and reasons for non-vaccination were investigated. A χ2 test and multiple logistic regression were used to identify independent predictors of full vaccination.
Results:
In total, 207 children were enrolled during the study period in 2014. Full measles vaccination coverage was 55% in these households, and 73% of parents were aware of the importance of measles vaccination to protect their children. We found that the father’s education level (under high school versus high school and above) and the site where the survey was conducted were significantly associated with vaccination status.
Conclusion
The vaccination coverage was lower than the coverage reported by district preventive medicine centres of the seven study wards. Lack of the second vaccination was a key obstacle to eliminating the vaccination gap. A catch-up mass vaccination campaign or health promotion of measles vaccination directed towards parents should be considered to improve vaccination coverage.

BACKGROUND: Human epidermal growth factor receptor 2 (HER2) is related to the pathogenesis and poor outcome of numerous types of carcinomas, including gastric carcinoma. Gastric cancer patients with HER2 positivity have become potential candidates for targeted therapy with trastuzumab. METHODS: We investigated 208 gastric cancer specimens using immunohistochemistry (IHC), fluorescence in situ hybridization and dual in situ hybridization (ISH). We also investigated the concordance between IHC and ISH. The correlation between HER2 status and various clinicopathological findings was also investigated. RESULTS: In total, 15.9% (33/208) and 24.5% (51/208) of gastric cancers showed HER2 gene amplification and protein overexpression, respectively. A high level of concordance between ISH and IHC analyses (91.3%, κ = 0.76) was found. A significant correlation between HER2 status and intestinal-type (p < .05) and differentiated carcinomas (p < .05) was also noted. The HER2 heterogeneity was high in gastric cancers; we found 68.8% phenotypic heterogeneity and 57.6% genotypic heterogeneity. Heterogeneity in HER2 protein expression and gene amplification showed a close association with diffuse histologic type and IHC 2+. CONCLUSIONS: HER2 protein overexpression and gene amplification were detected in 24.5% and 15.9% of gastric cancer specimens, respectively. Intestinal-type showed a higher level of HER2 protein overexpression and gene amplification than diffuse type. HER2 status also showed a significant relationship with well- and moderately-differentiated carcinomas. The ratio of phenotypic and genotypic heterogeneity of HER2 was high in gastric carcinomas and was associated with HER2 IHC 2+ and diffuse histologic type.
