This study carried out on 72 patients with secondary cerebroventricular hemorrhage and 115 patients with cerebral hemorrhage, without cerebroventricular apoplexy. The results showed that the cerebral hemorrhage in any area could lead to secondary cerebroventricular apoplexy. 65% of cases with thalamic hemorrhage had cerebroventricular apoplexy. The dimension of blood clot in the secondary cerebroventricular hemorrhage was larger than this in the cerebro parenchyma hemorrhage without apoplexy. The clinical characteristics included sudden crisis, conscious disorder, and cerebral stimulation. The mortality rate was 25%.

The study was conducted to compare bioavailability of rifampicin at the same doses with and without isoniazid and pyrazinamide in the standard separate tablets in 12 healthy volunteers. Bioavailability of rifampicin was estimated by plasma concentration of rifampicin from 0h to 24h after administration. Plasma rifampicin concentration was determined by HPLC method. The results revealed that Cmax and AUC for rifampicin was reduced (31.24% and 25.95%, respectively) when rifampicin - isoniazid - pyrazinamide was administeredat the same time. It was concluded that bioavailability of rifampicin was affected by presence of isoniazid and pyrazinamide.

Cross-sectional study was conducted in 6 handicraft villages, 600 producing households, 1.672 handicraft employees and 135 agricultural employees. The study results showed that: 98.4% of producing households had generated hazardous factors such as noise, heat, dust, micro-organism etc. In food processing village: 83.3% of micro-climate samples and 100% of light samples exceeded the permissible limits. In mechanical villages: 100% of noise sample accessed the permissible limit. In fine arts furniture villages: 91.3% of micro-climate sample, 75% of light sample and 69.5% of dust sample exceeded the permissible limits. In general, almost of handicraft employee had poor knowledge on risk factors at workplaces and their harms. The disease prevalence of handicraft employees was 85.3% that was higher than that of agricultural employee (58,5%). The difference was statistic significant (p=0.0001; RR= 1.46). Handicraft employee liked to have healthcare services at commune’s health station or have health workers at worker place and health insurance.

Background: Ventricular Septal Defect (VSD) is one of the most common congenital cardiac diseases, accounting for 20%, and affects the left ventricular function. There is no study on the application of Tei index to evaluate left ventricular function in patients with VSD in Vietnam. Objective:To assess left ventricular function in ventricular septal defect by Tei index. Subject and Method: A cross-sectional descriptive study that involves 35 patients of VSD with an average age of 15.77+/-10.41 (A group: 19 patients of VSD with systolic pulmonary artery pressure (PAPs) < 40 mmHg and B group: 16 patients of VSD with PAPs>=40mmHg and control group: 30 normal volunteers). Results: Tei index for estimation of left ventricular function is higher in the VSD (0.50+/- 0.18) than the control (0.37 +/- 0.03) with p < 0.01, exponentially more in the VSD with PAPs >=40mmHg (0.64 +/- 0.15; p<0.01). Conclusion: Left ventricular function is worse in VSD patients in comparison to the healthy people.

Several reports on taeniasis and cysticercosis in Vietnam show that they are distributed in over 50 of 63 provinces. In some endemic areas, the prevalence of taeniasis was 0.2-12.0% and that of cysticercosis was 1.0-7.2%. The major symptoms of taeniasis included fidgeted anus, proglottids moving out of the anus, and proglottids in the feces. Clinical manifestations of cysticercosis in humans included subcutaneous nodules, epileptic seizures, severe headach, impaired vision, and memory loss. The species identification of Taenia in Vietnam included Taenia asiatica, Taenia saginata, and Taenia solium based on combined morphology and molecular methods. Only T. solium caused cysticercosis in humans. Praziquantel was chosen for treatment of taeniasis and albendazole for treatment of cysticercosis. The infection rate of cysticercus cellulosae in pigs was 0.04% at Hanoi slaughterhouses, 0.03-0.31% at provincial slaughterhouses in the north, and 0.9% in provincial slaughterhouses in the southern region of Vietnam. The infection rate of cysticercus bovis in cattle was 0.03-2.17% at Hanoi slaughterhouses. Risk factors investigated with regard to transmission of Taenia suggested that consumption of raw meat (eating raw meat 4.5-74.3%), inadequate or absent meat inspection and control, poor sanitation in some endemic areas, and use of untreated human waste as a fertilizer for crops may play important roles in Vietnam, although this remains to be validated.

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.
