Background: Using social media (SM) for educational purposes might improve academic performance. Aim: This paper aims to describe health science students’ use of SM for educational purposes and its association with their academic performance. Methods: Two hundred ninety-seven undergraduate health science students completed a self-administered questionnaire comprising 4 sections related to social media. Results: Almost all students (99.7%) reported using SM for learning, most (90.9%) of them daily. The most preferred type of SM learning was Facebook. Most students thought that using SM for learning is convenient and useful. They suggested there should be 1 Facebook account for each subject, that every classmate could access to obtain knowledge from lecturers and to interact between students and lecturers. The logistic regression model showed that the more time students practiced following the advice on posted information, the more likely they were to achieve a GPA at distinction level or above (OR = 4.2; OR = 5.4, and OR = 9.4, respectively with times of practicing). Conversely, the students who used SM for learning less than once a month were less likely to obtain a GPA at distinction level (OR = 0.5). Conclusions: Almost all health science students used SM to support learning and use of SM for learning was associated with higher academic performance.

Along with the mechanism of quality assurance and accreditation that higher education system in Vietnam has been operating, university autonomy is a crucial factor in university governance, creating flexibility and dynamism for higher education institutions (HEIs), and increasing competitiveness among HEIs in the process of creating knowledge and leading the society to develop. The article clarifies the essence of university autonomy, the relationship between quality assurance, accreditation and university autonomy in Vietnam, thereby proposing solutions to promote autonomy for institutions to improve the efficiency and quality of higher education.

Objective: Dengue virus infection has diverse clinical manifestations often with unpredictableclinical evolution and outcome. This study was to evaluate the value of the peripheral blood cellin association with the severity of Dengue Infection. Method: This was an observational study on480 adult patients admitted to Bach Mai Hospital (Vietnam) with Dengue illness between Augustand October 2017. The diagnosis and classification of Dengue were based on WHO 2009 criteria.Blood samples were collected from patients during acute febrile phase time in hospital and theblood cell indices were analyzed. Results: A total 480 patients participated in the study including223 patients of Dengue without warning signs (A), 212 patients of Dengue with warning signs (B),and 45 patients of severe Dengue (C). B and C were considered as the severe group, and A wasclassified as the non-severe group. Compared to the non-severe group, the severe group hadsignificantly lowered hemoglobin, WBC, lymphocytes count and percentage of lymphocyte duringacute febrile phase on day 5 of illness. The percentagelymphocyte <25% was associated with the severe group. Conclusion: The percentage oflymphocytes, percentage of neutrophil are likely to predict for severity.

Background: Pneumonia is one of the serious complications during chemotherapy for acute leukemia. The purpose of this study was to determine the incidence rate, clinical characteristics, and risk factors for pneumonia in patients with acute leukemia after chemotherapy. Methods: Two hundred and nine patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) were enrolled in the cohort study,  in which 138 patients received chemotherapy, 71 patients had previous pneumonia, so chemotherapy should be delayed. Results:  Of the 138 patients who received chemotherapy, 40 patients (29%) developed pneumonia after chemotherapy. Post-chemotherapy pneumonia patients were less likely to have dypsnea, respiratory failure, and severity than those of previous pneumonia patients with P= 0.002, 0.004, and 0.012; respectively. Female patient, non-complete remission (CR) status (include: state of not reaching CR before or previous not received chemotherapy), neutrophil count delay below 0.5 G /L for 7 days, were risk factors for developing pneumonia after chemotherapy with P= 0.036, 0.002 and 0.005; respectively. Conclusions: Pneumonia after chemotherapy for acute leukemia was common. Female patients, non-CR status (include: state of not reaching CR before or previous not received chemotherapy), a delay in neutrophil count below 0.5G /L for 7 days, were  high- risk factors of developing pneumonia after chemotherapy.
