Objectives: Malaria prevention still faces many difficulties in the mountainous and highland areas, especially the provinces in the Central region and the Central Highlands, Vietnam. This study aims to describe the practice of malaria prevention of forest goers in four high-risk provinces of Vietnam in 2023 and some related factors. Methods: Cross-sectional in 696 foresters in 4 provinces: Gia Lai, Dak Lak, Dak Nong, Binh Phuoc, Vietnam from January 2023 to December 2023. The study used a validated questionnaire and convenience sampling method to select research subjects. Health station staff were trained as data collectors and supervised during data collection. Results: The study subjects with good malaria prevention practices accounted for 54.6%. In addition to sleeping under mosquito nets, subjects also applied other preventive measures such as wearing long-sleeved clothes and mosquito repellant cream, 83.1% and 67.8%, respectively. Gender, ethnicity, religion, education, health insurance, occupation, frequency of work in the forest, and good knowledge about malaria control as it relates to malaria prevention practices. Conclusion: The current status of malaria prevention practices among forest goers in four high-risk provinces is still limited. It is necessary to promote communication measures to improve people's knowledge, attitudes, and practices on malaria prevention

Objective: To provide preliminary descriptions of the spread, burden and related medical capacity characteristics of the ASEAN countries. Methods: We utilized the data from four main official databases, including WHO reports, the Statistics and Research of the Coronavirus Disease, and the Southeast Asia Program of the Center for Strategic and International Study. The spread of the COVID- 19 pandemic, current burden and the COVID-19 medical response capacities were extracted before April 11, 2020. Results: As of April 13, 2020, the ASEAN countries reported 19 547 COVID-19 positive cases with 817 deaths (case-facility rate of 4.2%). Thailand was the first country in the region that reported having the COVID-19 cases, while Laos was the last to report confirmed COVID-19 cases. Durations for the number of deaths to double were between 8-12 days. For the testing and treatment capacities, the number of PCR tests provided to the populations was the highest in Vietnam, followed by Singapore, Malaysia, and Thailand. Meanwhile, the percentage of the population being tested was the highest in Brunei (2.31%), followed by Singapore (1.30%). Conclusions: A wide range of interventions were taken into practice in response to the outbreak with an effort of curbing the rise of this pandemic. However, special care should not be overlooked as the pandemic is placing a huge impact on the population and becomes increasingly unpredictable. To tackle the spread of the pandemic in the region, the ASEAN countries should work together as one community to provide better responses to future pandemics and other transboundary public health challenges.

This longitudinal prospective study was carried out on 6 blood samples of 6 male volunteers at National Institute of Hematology and Blood Transfusion to examine the changes biochemical parameters, shape of blood cells, and variations of all blood components during blood store. Results: plasma Hb and K+ concentrations and LDH activity in stored blood increased significantly; plasma Na+ and Cl concentrations decreased significantly along the time. These variations occurred in the first week of store. There were changes in the shape of red blood cells during blood store.

Background: In many years, National Institute of Malariology, Parasitology and Entomology conducted collection, storage and preservation of malaria parasites species \r\n', u'Objective: to evaluate some results of malaria parasite species collected from Daknong province and analysis of drug resistance in P.Palciparum by the polymerase chain reaction.\r\n', u'Subject and method: Malaria parasite species collected from Daknong province in 2006. Thirty-five isolates were confirmed to be resistant with chloroquin by in vitro test. Polymerase chain reaction-restriction fragment leng polymorphism were used. \r\n', u'Results: 55 Plasmodium jalciparum. 7 Plasmodium vivax. 4 Plasmodium malariae. 1 Plasmodium ovale samples were collected from the malaria patients. A preliminary analysis of drug-resistant mutations in the Plasmodium jalciparum chloroquine resistance transpory (pfcrt) and P Jalciparummulti-drug resistant genes showed that the change of the order of amino-acid of Plasmodium jalciparum was closely correlated to chloroquine resistance in 35 isolates at the mutant allele 76 of pfcrt gene of chloroquine resistant Plasmodiuntjalciparum isolates. \r\n', u'Conclusion: These results contributed to supplement malaria parasite species that were stored in National Institute of Malariology, Parasitology ad Entomology.\r\n', u'
