MENTAL HEALTH CARE NEEDS OF STUDENTS AT HO CHI MINH CITY OPEN UNIVERSITY, VIETNAM Abstract Objective: Today’s life with changes in many aspects has brought people significant advantages and conveniences, but at the same time it has also caused physical and mental consequences for each person, especially mental health problems. Science has had many studies showing the impact of mental health on the quality of life, work efficiency, learning outcomes, etc. Therefore, when facing mental health problems, individuals need help to overcome the psychological problems they are facing to have healthier and more positive mental health. The scope of this study refers to the need for mental health care of students at Ho Chi Minh City Open University. Methodology: This study, based on theories of mental health, models and solutions to support mental health care, we built a questionnaire with 05 groups of basic needs to help students improve their physical and mental health for healthy mental health. Specifically, the care needs for self-satisfaction; The care needs for healthy emotional expression; the need to care for satisfaction in relationships with others; the full care needs are able to maintain a stable psychological state in life and the care needs for improving the ability to cope with difficulties in learning and working. After completion, we conducted a pilot survey on a small sample to check the reliability of the questionnaire and calibrate the scale. With an alpha coefficient of 0.98-meaning that the scale has a high reliability coefficient. Results: The mean score results show that all 05 groups of needs included in the study are of interest to the subjects and all have a desire to be met. Specifically: (1) The care needs for self-satisfaction has an mean score of 3.13 and a standard deviation of 0.73, a high level of need on the rating scale; care needs for expressing healthy emotions has an mean score of 3.45 and a standard deviation of 0.58, a very high level of need on the rating scale; the care needs for satisfaction in relationships with others has an mean score of 3.34 and a standard deviation of 0.65, a very high level of need on the rating scale; the full care needs are able to maintain a stable psychological state in life has an mean score of 4.42 and a standard deviation of 0.60, a very high need level in the assessment scale and the care needs for improving the ability to cope with difficulties in learning and working has an mean score of 3.19 and a standard deviation of 0.74, a high need level in the assessment scale. Conclusion: The research results show that students of Ho Chi Minh City Open University have a very high level of mental health care needs. Students clearly show mental health care needs in all the contents that need to be cared for. Among the component needs of mental health care needs, the need that students pay more attention than the remaining needs is the full care needs are able to maintain a stable psychological state in life. The need that students care less about than the remaining needs is the care needs for self-satisfaction. ASEAN Journal of Psychiatry, Vol. 25 (10) December, 2024; 1-13.

Aims: This study was aimed to test the specificity of primers and probes with target genes by using multiplex PCR and multiplex real-time PCR methods. These methods were compared with traditional blood culture methods in detecting five bacteria causing sepsis, including Acinetorbacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus. Methodology and results: A total of 587 blood samples from patients diagnosed with sepsis and septic shock were collected at Thanh Nhan Hospital, Hanoi, Vietnam. Each sample was divided into three parts for bacterial culture, multiplex PCR and multiplex real-time PCR to detect the similarity of the two PCR methods with the bacterial culture method. Conditions in multiplex PCR and multiplex real-time PCR were optimized to ensure the successful amplification of target genes. Results showed that the primers and probes were tested completely specific to the target genes and using multiplex PCR and multiplex real-time PCR techniques could detect five pathogens causing sepsis, including A. baumannii, K. pneumoniae, P. aeruginosa, E. coli and S. aureus. Conclusion, significance and impact of study Both multiplex PCR and multiplex real-time PCR methods have high similarities with the culture method, showing potential in the application of bacteria detection in sepsis.

Tannic acid (TA) is a water-soluble polyphenol compound found in various herbal plants. We investigated the chemopreventive effects of TA on FaDu hypopharyngeal squamous carcinoma cells. In an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, TA showed dose-dependent cytotoxicity with a half maximal inhibitory concentration (IC50) of 50 µM. Cell cycle analysis and immunofluorescence imaging demonstrated that under low-dose (25 µM) treatment, FaDu cells were arrested in G2/M phase, and as the dose of TA was increased, apoptosis was induced with the increase of cell population at sub-G1 phase. The expressions of various cyclins, including cyclin D1 and cyclin-dependent kinases (CDK-1 and CDK-2), were down-regulated at low doses of TA, whereas apoptotic effectors such as cleaved caspase 3, cleaved caspase 7, and poly (ADP-ribose) polymerase (PARP) were expressed in a dose-dependent manner in Western blotting. In addition, TA-induced apoptosis of FaDu cells might be mediated by the extracellular signal-regulated kinase (ERK)/mitogen-activated protein kinase pathway, with the upregulation of p-AKT/p-PKB (phosphorylated protein kinase B) and p-ERK. Overall, our data support the hypothesis that TA is a potential candidate agent for the treatment of hypopharyngeal cancer.

The present study was performed to reveal the morphological characteristics and molecular phylogenetic position of Platynosomum fastosum Kossack, 1910. A total 167 specimens of P. fastosum were collected in 8 (4.9%) out of 163 sets of gall-bladders and bile ducts of cats. The number of worms was 1–105 per infected cat. This species was characterized by having a long and slender body, slightly larger ventral sucker than the oral sucker, indistinct prepharynx, small pharynx, short esophagus, bifurcation midway between 2 suckers, and ceca extending to the posterior end of the body. The length of the partial sequences of ITS1 and 5.8S rDNA of P. fastosum were 990 bp, GC-rich. AT/GC ratio was 0.9, there were 9 polymorphic sites, and intraspecific variations ranged from 0.1% to 0.9%. Phylogenetic analyses by neighbor-joining phylogram inferred from ITS1 rDNA sequences revealed that the genetic distance between P. fastosum specimens ranged from 0.3 to 1.5% while the smallest interspecific distance among dicrocoeliid species was 20.9 %. The redescription and genetic characters of P. fastosum are taxonomically important to recognize future different species of the genus Platynosomum showing high intraspecific and morphological variability.

Objective To characterize viral co-infections among representative hospitalized measles cases during the 2014 Hanoi outbreak. Methods Throat swabs were collected from 54 pediatric patients with confirmed measles, and molecular diagnostics performed for 10 additional viral respiratory pathogens (Influenza A/H1N1pdm09; A/H3N2 and influenza B; Parainfluenza 1, 2, 3; Respiratory Synctial Virus, RSV; human Metapneumovirus, hMPV; Adenovirus and Picornavirus). Results Twenty-one cases (38.9%) showed evidence of infection with other respiratory viruses: 15 samples contained measles plus one additional virus, and 6 samples contained measles plus 2 additional viruses. Adenovirus was detected as a predominant cause of co-infections (13 cases; 24.1%), followed by RSV (6 cases; 11.1%), A/H1N1pdm09 (3 cases; 5.6%), PIV3 (3 cases; 3.7%), Rhinovirus (3 cases; 3.7%) and hMPV (1 case; 1.96%). Conclusions Viral co-infections identified from pediatric measles cases may have contributed to increased disease severity and high rate of fatal outcomes. Optimal treatment of measles cases may require control of multiple viral respiratory pathogens.

Background: Recently Japanese Encephalitis (JE) virus type 1 has surfaced and is co-circulated with JE virus type 3 in the northern areas of Viet Nam, so a sensitivity of JE viral antigen genotype 3 to detect IgM is required. Objectives: To compare the sensitivity of JE viral antigen genotype 1 and 3 to detect IgM against the JE virus. Materials and method: 783 cerebrospinal fluid and serum samples from viral encephalitis cases from 1999-2005 were collected and examined by MAC-ELISA for JE viral antigen genotype 1 and 3. Results: The agreement on the diagnosis of these kinds of antigen was 99.7% and the sensitivity of JE viral antigen genotype 3 was higher than that of genotype 1. Thus, JE viral antigen genotype 3 could be considered as the selected antigen for JE diagnosis in Viet Nam. IgM titer determined by JE viral antigen genotype 1 was higher than that of genotype 3 in 2003 and 2005 and lower in 1999, 2000, 2001, 2002 and 2004. Conclusion: The dominant phenomenon of JE viral genotypes differing over the years might be due to the interaction of the virus and its vectors. Further study is required to clarify this observation.

Background: Japanese Encephalitis (JE) is common in the plains and mountainous areas in Asia \u2013 Pacific. Japanese encephalitis vaccine shows effectiveness in protecting children from JE in some countries such as Japan and Korea. Objective: To evaluate the efficacy of Japanese Encephalitis (JE) vaccination in Thai Binh province during 2003-2007. Subject and Method: Prospective, retrospective and sero-epidemiological methods were carried out on 329 samples collected from viral encephalitis patients and tested by JE MAC-ELISA, the positive average was 41.6% (137/329). Result: It had dramatically dropped from 85.2% in 2003 to 8.5 % in 2007 related to the rate of JE vaccination for children from 1 to 5 years old increasing from 49 % in 2003 to 77 % in 2007. Most of JE confirmed cases were un-vaccinated. Conclusion: JE etiology cause viral encephalitis in children in Thai Binh province was reduced thanks to JE vaccination in EPI program for 1 to 5 year old children. But more than 96% (131/136) of viral encephalitis in 15 years old upward was unknown etiology, the need for further study of the etiology cause viral encephalitis in adults.

Background: IgM antibody capture ELISA (MAC-ELISA) technique has been widely applied for Japanese Encephalitis Virus (JEV) diagnosis. So far rare internationally commercial kits are available. Thus, the international evaluation of the kit is required as per the recommendation of the WHO. Objectives: To evaluate the quality of the IgM antibody capture ELISA diagnostic kit for JEV produced by the Vietnam National Institute of Hygiene and Epidemiology (NIHE). Subjects and method: In this study, NIID kit was used as control to check the kit from NIHE. Both NIHE and NIID kits were used to detect JEV IgM among 38 serum and 6 CFS samples, which belongs to 5 sample groups (JE patients group, dengue patients group, other viral encephalitis patients group, Tick Born Encephalitis (TBE) patient group and healthy JE vaccinated donors group). Results: The detection of JEV IgM by NIHE kit was concurrent with the NIID kit. There is no positive with the JE in the groups of Dengue patients, TBE, other virus encephalitis patients and JE vaccinated donors. Conclusion: MAC-ELISA kit of NIHE can be used for different diagnosis of JEV and Dengue virus (both viruses are in Flavivirus genus), as well as other viruses caused by encephalitis.
