ABSTRACT

Mental health disorders among university students have been a serious issue in many countries and can negatively affect academic performance and all aspects of daily living, relationships, and physical health. In this study, we aim to estimate the prevalence of severe symptoms of mental disorders and examine associated factors among students majoring in foreign languages in Vietnam. We used the Depression, Anxiety, and Stress Scales (DASS-21) to detect severe symptoms of mental disorders in 1,788 students, including severe symptoms of depression, anxiety, and stress. The Financial-Study-Family-Friend (FSFF) scale was utilized to assess how much students worried about finance, academic, and social support from family and friends. Multiple logistic regressions were carried out to evaluate the relationship between severe symptoms of mental disorders and FSFF factors. The prevalence of severe levels of depression, anxiety, and stress were 21.1, 35.0, and 16.3%, respectively. While varying somewhat due to students' demographic characteristics, all four aspects of the FSFF scale were related to the severe symptoms of mental disorders of students. Concerns about study had the largest effects (ORs ranging from 2.84 to 3.72) while difficulty in finance had the smallest effects (ORs ranging from 1.23 to 1.37) on students' depression, anxiety, and stress. The prevalence of severe symptoms of mental disorders in students was high in our study. Teachers and universities should focus more attention on students' mental health. Social support from family and friends also plays a crucial role in the mental health of students.

ABSTRACT

The detection of gametocytes in human peripheral blood is one of the most important measures in a malaria survey. We attempted to detect gametocytes of Plasmodium falciparum by reverse transcription polymerase chain reaction (RT-PCR) of dried blood on filter paper. On field samples analysis, the specific RT-PCR products for region 3 of pfg377 mRNA were observed in 67 of 131 falciparum malaria patients. The minimum detection level of RT-PCR-positive samples was 0.03 gametocytes/microl on quantitative real-time RT-PCR. Gametocyte positive rate was not dependent on sex or age. A higher frequency of gametocytes was found in single P. falciparum infection than in mixed species infection (P<0.01). In this study, 47 of the 131 patients were asymptomatic. Eighteen of these 47 patients showed pfg377 mRNA expression. Moreover, four alleles of region 3 of pfg377 were detected in pfg377 mRNA-positive patients and 13 of 67 pfg377 mRNA-positive patients carried more than one gametocyte-producing clone. These results suggest that dried blood on filter paper is a useful for a molecular epidemiologic study of malaria transmission and gametocyte-targeted control.

ABSTRACT

We examined the role of osteopontin (OPN) in immunity against Plasmodium falciparum infection. We measured the mRNA levels for OPN and several cytokines in RNA preparations extracted from dried blood on filter paper obtained from falciparum malaria patients in Vietnam. Expression of OPN mRNA was detected in 134 of 161 patients. The expression of both interleukin-12 p40 and interferon-gamma mRNAs in the group positive for OPN mRNA was significantly higher than that in the group negative for OPN mRNA. The level of parasitemia in the OPN mRNA-positive group was much lower than that in the negative one. These results suggest that OPN might suppress multiplication of the parasites through T helper 1 cells-mediated immune responses.
