Objective: This study aimed to assess the diagnostic performance of the Risk of Ovarian Malignancy Algorithm (ROMA), Copenhagen Index (CPH-I), and Ovarian Adnexal Reporting and Data System (O-RADS) for the preoperative prediction of ovarian cancer (OC). Methods: A prospective cohort study was conducted on 462 patients diagnosed with ovarian tumors admitted to the Departments of Obstetrics and Gynecology, Hue University of Medicine and Pharmacy Hospital, and Hue Central Hospital from May 2020 to December 2022. ROMA and CPH-I were calculated using cancer antigen 125 (CA125), human epididymal protein 4 (HE4) levels, and patient characteristics (age and menopausal status). O-RADS criteria were applied to describe ovarian tumor characteristics from ultrasound findings.Compared with histopathological results, the predictive values of ROMA, CPH-I, and O-RADS alone or in combination with CA125/HE4 for OC were calculated. Results: Among 462 patients, 381 had benign tumors, 11 had borderline tumors, and 50 had OC. At optimal cut-off points, ROMA’s and CPH-I’s areas under the curves (AUCs) were 0.880 (95% confidence interval [CI]=0.846–0.909) and 0.890 (95% CI=0.857–0.918), respectively, and ROMA and CPH-I sensitivities/specificities (Se/Sp) were 68.85%/95.01% and 77.05%/91.08%, respectively. O-RADS ≥3 yielded an AUCs of 0.949 (95% CI=0.924–0.968), with Se/Sp of 88.52%/88.98% (p<0.001). Combining O-RADS with CA125 demonstrated the highest predictive value, with AUCs of 0.969 (95% CI=0.949–0.983) and Se/Sp of 98.36%/86.09% (p<0.001). Conclusion The ROMA, CPH-I, O-RADS, O-RADS + CA125, and O-RADS + HE4 models demonstrated good predictive values for OC; the combination of O-RADS and CA125 yielded the highest values.

Background: The genus Alpinia is one of the diverse genera in Thua Thien Hue province, in which many species have been used as medicine. But until now, studies on A. vietnamica have rarely been reported. Objectives: The present study was aimed at the determination of microscopic characteristics and chemical compositions as well as evaluating the antioxidant and acetylcholinesterase inhibitory activities of A. vietnamica. Materials and methods: A. vietnamica was collected in Phong Dien district, Thua Thien Hue province. Anatomic structures and powder properties were determined by the microscopic method. Phytochemical screening was conducted by specific chemical reactions. The Folin-Ciocalteau method and the aluminum chloride-flavonoid assay, respectively, were used to quantify the total polyphenol (TPC) and total flavonoid contents (TFC). Antioxidant activity was assessed using the DPPH assay, while acetylcholinesterase (AChE) inhibitory activity was evaluated using the Ellman method. Results: The microscopic characteristics of this species have been described. Phytochemical analysis results revealed the presence of flavonoids, coumarins, and tannins in A. vietnamica. The ethanol extract from the aerial part of A. vietnamica had higher polyphenol and flavonoid contents than the underground part extract. Moreover, this extract also displayed a stronger DPPH radical scavenging and exhibited AChE inhibitory activities. Conclusion: This is the first report on the microscopic characteristics, chemical compositions, and biological activities of A. vietnamica.

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.

Backgroud: The aim of this study is to update on antibiotic resistance of common pathogenical bacteria isolated in Hue University of Medicine and Pharmacy Hospital (Hue UMP Hospital). Methodology: Use of the agar disk diffusion method to test the susceptibility to antimicrobial agents of 3709 bacterial strains from infected patients hospitalized in Hue UMP Hospital in 2020 - 2022. Results: Among 3709 strains of pathogenical bacteria isolated, S.aureus was found with the rate of 29.9%, followed by E. coli (24.5%), Pseudomonas aeruginasa (17.8%), Enterococcus spp. (11.8%), Klebsiella spp (9.7%) and Acinetobacter spp (4.1%). The proportion of bacterial isolates has changed, but Staphylococcus aureus is still highest rate. S.aureus is resistant to many antibiotics, but MRSA strains have decreased significantly, from 73.3% in 2020 to 62.5% in 2022. Pseudomonas aeruginosa was resistant to some of the group A recommended antibiotics such as ceftazidime, piperacillin-tazobactam with the rate of 56.6% and 48.7%. The percentage of E. coli with ESBL strains (+) was at 28.2% - 30.3%. Enterococus spp strains are still sensitive to vancomycin (83.1% - 91.9%). The rate of Klebsiella ESBL (+) is only 6.9% to 8.2%. The strains of Acinetobacter spp were highly resistant to Piperacillin (100%) and Ceftriaxone (96.5%) but they are still sensitive to imipenems 70 - 71%, highly sensitive to Doxycillin (95.2%) and Cefotaxime (88.4%). Conclusion: Many bacterial strains are resistant to many commonly antibiotics. Providing timely, regular, and effective management of antibiotic resistance patterns for common pathogenic bacteria in hospitals, will help reduce the risk of bacterial resistance.

The aim of this study is to delineate ‘admixed hybrid’ and ‘introgressive’ Fasciola genotypes present in the Fasciola population in Vietnam. Adult liver flukes collected from ruminants in 18 Provinces were morphologically sorted out by naked eyes for small (S), medium (M) and large (L) body shapes; and human samples (n=14) from patients. Nuclear ribosomal (rDNA) ITS1 and ITS2, and mitochondrial (mtDNA) nad1 markers were used for determination of their genetic status. Total 4,725 worm samples of ruminants were tentatively classified by their size: 6% (n=284) small (S)-, 13% (n=614) medium (M)-, and 81% (n=3,827) large (L)-forms. All the representative (n=120, as 40 each group) and 14 human specimens, possessed maternal mtDNA of only F. gigantica and none of F. hepatica. Paternally, all (100%) of the L-(n=40) and 77.5% (n=31) of the M-flukes had single F. gigantica rDNA indicating ‘pure’ F. gigantica. A majority (90%, n=36) of the S- and 15% (n=6) of the M-worms had single F. hepatica rDNA, indicating their introgressive; the rest (10%, n=4) of the S- and 7.5% (n=3) of the M-flukes had mixture of both F. gigantica and F. hepatica rDNAs, confirming their admixed hybrid genetic status. Fourteen human samples revealed 9 (64%) of pure F. gigantica, 3 (22%) of introgressive and 2 (14%) of admixed hybrid Fasciola spp. By the present study, it was confirmed that the small worms, which are morphologically identical with F. hepatica, are admixed and/or introgressive hybrids of Fasciola spp., and able to be the pathogens of human fascioliasis.

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.

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.

Hereditary angioedema (HAE) is rare disorder due to C1-inhibitor deficiency (C1-INH) that are debilitating and may be life-threatening. HAE is a lack of consensus concerning diagnosis, therapy, and management, particularly in Vietnam. In this case report, we report a 40-year-old male patient with typical clinical symptoms and family history but he showed normal C4 level, and we could not measure C1q and C1-INH level. However, the diagnosis of HAE can be made based on typical clinical symptoms and the favorable prophylactic response to danazol treatment. Based on these findings, we suggest that he has type I HAE, although he showed normal C4 level.

Background: Situation of extremity injury caused by traffic accidents and occupational accidents are increasing in Vietnam. Therefore, the prevention and fight against these accidents are one of the key objectives to reduce the burden on the families of victims as well as for society. Objectives: To outline situation of extremity injury patients caused by traffic accident, treated in Viet Duc hospital from 2000-2004. Subjects and method: A retrospective study was conducted on 19.845 patients (14.562 males, 5.283 females, aged from 1-97 years old). The subjects were divided into 3 main groups: alone upper extremity injury, alone lower extremity injury and multiple fractures. Results: Extremity injury was common seen in people of working age (78.1%), men more than women (2.76/1 ratio), left foot more than right foot and it was common been in multiple fracture situation due to complex mechanisms of injury (50.3%), alone extremity injury (49.7%). The lower extremity injury was more common seen than upper extremity injury. Open fracture injury (27.3%), in which open fractures in lower extremity were more common seen. Open fractures in both 2 leg bones was the most common seen, accounted for 57.4% among total of open fractures. Amputation accounted for 8.3% among all case of open fractures and 2.3% among all case of extremity injuries. Conclusion: Extremity injury (lower extremity and upper extremity) caused by traffic accidents is common seen. The average, there are 3 emergency surgeries due to open fracture injury were performed daily in Viet Duc hospital per a total of about 11 traumatic emergency surgeries.
