100 patients involving Cervical Spinal Stenosis have been operated on from 10/1995- 9/1999 in the Spinal Surgery Dep. A Centre for Trauma- orthopedics in HCM city. The clinical data was as following: 32 cases involving Cervical Spondylosis; 63 cases involving Cervical Disc Herniation; 5 OPLL and CDH. Mean age: 49, 95 (29-76). Men: 69. Women: 31. 85 surgical interventions for 81 patients using Anterior Decompression and Fusion for one to three stages (4 reoperated cases: 2 epidural hematomas and 2 graf dislocations). 19 cases operated by posterior Approaches: two laminectomy, 17 using the KUROKAWA technique with four technical failure (turned to ITOH in two cases and lamiectomy in two cases). Grafting technique used: argenson 1, Bailey-Badgley 5, Bohlman 11, Bohlman and Kokubun 1, Kokubun 45, Kokubun for 2 different stages 1, Smith-Robinson and Kokubun for two different stages 1. Good fusion was obtained in all of the cases using the Anterior Decompression and Grafting. The recovery rate for whole group was 71% following the Scale of JOA. 71/87 cases accompanied by the neurological deficits recovered from motor weakness. Among them, there were 60,56% complete recovery, 39.44% partial recovery. 52/81 cases with anterior decompression and arthrodesis were followed between 3 to 39 months. 35 of them have been reviewed further 12 months. 11 of 19 cases operated by laminaplasty have been reviewed from 9 to 29 months. 9 of them with follow-up more than 12 months. Surgical treatment is really an effective method for Cervical Spinal stenosis. The skillfull surgical decompression techniques should be practiced.

Background: In many years, National Institute of Malariology, Parasitology and Entomology conducted collection, storage and preservation of malaria parasites species \r\n', u'Objective: to evaluate some results of malaria parasite species collected from Daknong province and analysis of drug resistance in P.Palciparum by the polymerase chain reaction.\r\n', u'Subject and method: Malaria parasite species collected from Daknong province in 2006. Thirty-five isolates were confirmed to be resistant with chloroquin by in vitro test. Polymerase chain reaction-restriction fragment leng polymorphism were used. \r\n', u'Results: 55 Plasmodium jalciparum. 7 Plasmodium vivax. 4 Plasmodium malariae. 1 Plasmodium ovale samples were collected from the malaria patients. A preliminary analysis of drug-resistant mutations in the Plasmodium jalciparum chloroquine resistance transpory (pfcrt) and P Jalciparummulti-drug resistant genes showed that the change of the order of amino-acid of Plasmodium jalciparum was closely correlated to chloroquine resistance in 35 isolates at the mutant allele 76 of pfcrt gene of chloroquine resistant Plasmodiuntjalciparum isolates. \r\n', u'Conclusion: These results contributed to supplement malaria parasite species that were stored in National Institute of Malariology, Parasitology ad Entomology.\r\n', u'

Objectives: The prevalence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association. Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnamfrom December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (usingthe 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions. Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD.Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.63–2.12; p < 0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p = 0.001). Compared to those without long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p = 0.001). Conclusion Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.

Background: Suicide continues to be a leading cause of death worldwide. Recently, more than 45,000 children in the age group of 10 to 19 years died by suicide, making it the second leading cause of death in the age group of 15 to 19, surpassed only by traffic accidents, tuberculosis, and fighting. Objective: To determine the prevalence of suicidal ideation among adolescents whose parents are separated/divorced; and to explore the factors associated with suicidal ideation and describe adverse experiences among adolescents. Methods: A cross-sectional descriptive study was conducted in 309 adolescents with separated/separated parents in Hue City. Data was collected through direct interviews using a structured questionnaire. Suicidal ideation was defined as the presence of thoughts or plans related to suicide within the last 12 months. Multivariate logistic regression was applied to identify factors associated with suicidal ideation in adolescents with separated/ separated parents. Results: The study found that 15.5% (95% CI:11.7 - 20.1) of adolescents with separated /separated parents reported experiencing suicidal thoughts, in which men accounted 8.4% (95% CI:5.6 – 11.2) and women accounted 7.1% (95% CI:4.5 - 10.6). Several factors were identified as increasing the risk of suicidal ideation, including alcohol use (OR = 3.24; 95% CI:1.42 - 7.42), hyperactivity/inattention (OR = 4.96; 95% CI:1.58 - 15.605), and a poor quality of family relationships (OR = 4.82; 95% CI:1.26 - 18.50). On the contrary, certain factors were found to reduce the risk, including being in the 14-15 age group of 14-15 (OR = 0.26; 95% CI:0.10 - 0.69) and participating in physical activity (OR = 0.44; 95% CI:0.21 – 0.94). Conclusions: The research highlights a significant percentage of adolescents with separated / divided parents who experience suicidal ideation. Therefore, it is imperative for families, schools, and society to develop comprehensive strategies to monitor and address various risky behaviours among students simultaneously.

As authorities braced for the arrival of the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), infrastructure investments and government directives prompted action in central Viet Nam to establish capacity for genomic surveillance sequencing. From 17 November 2021 to 7 January 2022, the Pasteur Institute in Nha Trang sequenced 162 specimens from 98 150 confirmed SARS-CoV-2 cases in the region collected from 8 November to 31 December 2021. Of these, all 127 domestic cases were identified as the B.1.617.2 (Delta) variant, whereas 92% (32/35) of imported cases were identified as the B.1.1.529 (Omicron) variant, all among international flight passengers. Patients were successfully isolated, enabling health-care workers to prepare for additional cases. Most (78%) of the 32 Omicron cases were fully vaccinated, suggesting continued importance of public health and social measures to control the spread of new variants.

Objective: To investigate the cause of a foodborne outbreak that occurred in Dong Nai province, Viet Nam, in 2024, and implement control measures. Methods: An initial investigation was conducted to confirm the outbreak, which was followed by epidemiological and environmental investigations to find the plausible causative food item. Clinical specimens and food samples were tested to identify the pathogen. Results: A total of 547 symptomatic cases were recorded, of whom two were in severe condition requiring extracorporeal membrane oxygenation and ventilation, one of whom died. Among 99 interviewed cases, the mean incubation time was 9 hours (range 2–24 hours), with the main symptoms being fever, abdominal pain, diarrhoea and vomiting. All patients had eaten banh mi from a local bakery. Salmonella spp. were identified in food samples and clinical specimens. The bakery halted production, and the outbreak ended after 1 week. Discussion: All the patients were exposed to only one food in common, which facilitated the investigation process. This outbreak is a reminder to small retailers and take-away shops of the importance of food safety management in preventing similar future outbreaks. All food handlers must comply with food hygiene principles, especially in hot temperatures, which boosts bacterial growth.
