The definitive diagnosis of nasopharyngeal carcinoma (NPC) depends on the examination of tissue or cells obtained from either the primary site or a metastatic focus. 1120 patients suffering from NPC were reviewed. 880 patients (76.52%) had fine needle aspiration (FNA) in cervical lymph nodes (positive: 84.83%, Se: 95.52%, Sp: 100%, PV(+): 100%, PV(-):57.14%, A:94.37%) 132 patients (11.79%) performed on smears collected from biopsy tissue (positive rate: 63.64%, Se: 84%, SP: 100%, PV(+): 100%, PV(-): 66.67%, A: 87.88%.

Background: Each of the zone there has a different context for soil-transmitted helminth disease to exist and develop. Objectives: (1) To define the soil-transmitted helminth infection prevalence situation. (2) To define knowledge and practice about soil-transmitted helminth diseases prevention in Ea Tieu commune. Subject and method: The Ede ethnic population community lives in Ea Tieu and using a cross-sectional study. Results and conclusions: Ea Tieu commune, Krong Ana district, Daklak province, that has rather high soil-transmitted helminth general prevalence about 74.1 %, the highest prevalence is Ascaris lumbricoides infection, about 53.7%, next is hookworm with 38.4%, and the lowest is Trichuris trichiura with 1.3%. The Ascaris lumbricoides infection prevalence is not that different between age group (2 - 15: 58.98% in comparison with over 16: 50.87%) and hookworm infection prevalence was different between two age group that are 2-15: 6.05% which is lower than over 16: 55.99%. Average of intensity infection (average of eggs per gram of faeces) belongs to low intensity infection. Knowledge and practice about worm infection prevention of Ede ethnic in Ea Tieu is very low: 29.8% people does not rightly know of any harm, 24.6% people know one of the reasons is because of unclean food, 16.3% and another reason because of unclean hands with 16.3%, only 6.1 % people know the reason for hookworm infection.
Soil-transmitted helminth infection

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.
