1506 Phan Hoµi Trung: Some convenient factors for haemorrhoid thrombosis: Vn J Med 2001 Aug.,262(8):64-67:(CIMSI) By studying 106 cases of hemorrhoid thrombosis, the statistical significant high risk factors promoting thrombosis are bleeding antecedent, weather changes, strenous overworking, wine. With the combination of these 4 factors, the thrombosis risks are up to 38.6-42.5%.

“Sinh tinh thang”, a traditional remedy for stimulating spermatogenesis was applied in a clinical trial in patients suffering from idiopathic hypospermia. 111 patients, under 56 years old, were studied. Two months after treatment by “Sinh tinh thang”, the concentration of spermatozoons (from 40.96 x 10-6/ml up to 57.47 x 10-6/ml) and rate of rapid moving spermatozoons (from 6.04% up to 10.38%) also increased considerably in general

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.
