    Abstract: In the coastal countries of Southeast Asia, fish is a staple diet and certain fish species are food delicacies to local populations or commercially important to individual communities. Although there have been several suspected cases of ciguatera fish poisoning (CFP) in Southeast Asian countries, few have been confirmed by ciguatoxins identification, resulting in limited information for the correct diagnosis of this food-borne disease. In the present study, ciguatoxin-1B (CTX-1B) in red snapper (Lutjanus bohar) implicated in a CFP case in Sabah, Malaysia, in December 2017 was determined by single-quadrupole selected ion monitoring (SIM) liquid chromatography/mass spectrometry (LC/MS). Continuous consumption of the toxic fish likely resulted in CFP, even when the toxin concentration in the fish consumed was low. The identification of the fish species was performed using the molecular characterization of the mitochondrial cytochrome c oxidase subunit I gene marker, with a phylogenetic analysis of the genus Lutjanus. This is the first report identifying the causative toxin in fish-implicated CFP in Malaysia.

    Abstract: Plasmodium falciparum is the main cause of human malaria and is one of the important pathogens causing high rates of morbidity and mortality. The total number of malaria patients in Vietnam has gradually decreased over the last decade. However, the spread of pathogens with drug resistance remains a significant problem. Defining the trend in genotypes related to drug resistance is essential for the control of malaria in Vietnam. We undertook a longitudinal survey of Plasmodium falciparum malaria in 2001, 2002, and 2005 to 2007. The pfcrt , pfmdr1 , pfdhfr , and pfdhps genes were analyzed by sequencing; and correlations by study year, age, gender, and genotype were identified statistically. The ratio of the chloroquine resistance genotype pfcrt 76T was found to have decreased rapidly after 2002. High numbers of mutations in the pfdhfr and pfdhps genes were observed only in 2001 and 2002, while the emergence of parasites with a new K540Y mutation in the P. falciparum dihydropteroate synthetase (PfDHPS) was observed in 2002. For males and those in younger age brackets, a correlation between vulnerability to P. falciparum infection and strains with pfcrt 76K or strains with decreased numbers of mutations in pfdhfr and pfdhps was demonstrated. The parasites with pfcrt 76T exhibited a greater number of mutations in pfdhfr and pfdhps .

    Abstract: Meadia minor sp. nov., a scaless ilyophine eel, is described on the basis of 10 specimens collected from off Quy Nhon, central coast of Vietnam. It can be distinguished from its congeners in having a relatively long trunk (21.3–25.0% TL) which is longer than head length; a short and blunt snout (21.4–23.7% HL); gill opening close to pectoral-fin base; interbranchial space broad (20.7–26.2% HL); dorsal-fin origin above posterior third of pectoral fin; body depth 24–28 times in TL; total vertebrae 118–122; mean vertebral formula 7-33-121; and a small body size, reaching 330 mm TL. The generic status of the new species is discussed. Short descriptions of two congeners are provided.

    Abstract: Mục tiêu: Đánh giá kết quả điều trị chửa ngoài tử cung tại Bệnh viện Quân y 103 trong 2 năm (2020-2022). Đối tượng và phương pháp: nghiên cứu tiến cứu cắt ngang trên 111 bệnh nhân chửa ngoài tử cung điều trị nội trú tại Bệnh viện Quân Y 103 từ tháng 6/2020 đến tháng 5/2022. Kết quả:  Tuổi trung bình là 32,68 ±5,55 tuổi, từ 25-35 tuổi chiếm 54%, 74,78% bệnh nhân được điều trị bằng phẫu thuật nội soi, 27,72% điều trị bằng phẫu thuật mổ mở, còn lại là điều trị nội khoa bằng methotrexat (MTX) (4,5%). Bệnh nhân được nhân từ 1-3 liều MTX, 65,22% bệnh nhân dùng 1 liều MTX.  Có 97,73% cắt vòi tử cung chứa khối thai, bảo tồn vòi tử cung chiếm 2,27%. Thời gian trong phẫu thuật dưới 60 phút chiếm tỉ lệ 84,09%, thời gian trung bình mổ mở là 47,2±3,03 phút, phẫu thuật nội soi là 55,73±16,58 phút. Thời gian nằm viện trung bình điều trị bằng MTX là 6,65±2,93 ngày, điều trị bằng mổ mở 5±2,12 ngày, phẫu thuật nội soi là 3,47±0,89 ngày. Kết luận: tỉ lệ điều trị nội khoa 27,72%, mổ mở 4,5%, phẫu thuật nội soi 74,78%. Phẫu thuật nội soi điều trị chửa ngoài tử cung có thời gian nằm viện trung bình ngắn nhất, sự khác biệt với mổ mở và điều trị nội khoa có ý nghĩa thống kê. Chỉ định điều trị nội khoa đơn liều ở các trường hợp CNTC chưa vỡ, không có triệu chứng lâm sàng, siêu âm khối thai dưới 3,5cm, chưa có phôi, nồng độ βhCG máu dưới 3000mUI/ml, tỉ lệ thành công với phác đồ đơn liều là 100%. Chỉ định PTNS điều trị CNTC ở các trường hợp không còn chỉ định điều trị nội khoa, những trường hợp khối thai vỡ có sốc đã hồi sức, huyết áp ổn định. Chỉ định PTMB điều trị CNTC những trường phợp sốc mất máu, huyết động không ổn định sau khi đã hồi sức tích cực.

    Abstract: Helicobacter pylori (H. pylori) infection is prevalent and has a rapidly increasing antibiotic resistance rate in Vietnam. Reinfection is quite common, and gastric carcinoma remains one of the most common malignancies, which is not uncommon to develop after successful eradication. The purpose of this consensus is to provide updated recommendations on the management of H. pylori infection in the country. The consensus panel consisted of 32 experts from 14 major universities and institutions in Vietnam who were invited to review the evidence and develop the statements using the Delphi method. The process followed the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The consensus level was defined as ≥80% for agreement on the proposed statements. Due to the limited availability of high-quality local evidence, this consensus was also based on high-quality evidence from international studies, especially those conducted in other populations in the Asia–Pacific region. The panel finally reached a consensus on 27 statements after two voting rounds, which consisted of four sections (1) indications for testing and selection of diagnostic tests (2), treatment regimens, (3) post-treatment confirmation of H. pylori status, and (4) reinfection prevention methods and follow-up after eradication. Important issues that require further evidence include studies on third-line regimens, strategies to prevent H. pylori reinfection, and post-eradication follow-up for precancerous gastric lesions. We hope this consensus will help guide the current clinical practice in Vietnam and promote multicenter studies in the country and international collaborations.

    Abstract: The marine actinomyces Micrococcus was the most common bacterium among the isolates corals, sponges, and alga isolates. Only a few investigations of natural compounds from Micrococcus sp. were reported previously. This study implicated the soft coral-associated Micrococcus sp. strain A-2-28 (following relative Micrococcus flavus LW4T) for large-scale cultivation, chemical analyses, and biological activities. Whereas crude extract of the strain A-2-28 inhibited only Staphylococcus epidermidis, metabolites profiles and pure compounds from strain A-2-28 showed that this strain produced phytohormone (IAA), metabolized some new compounds which were almost inactive for biological tests. This work suggested that it is possible to plan a new strategy for improving coral health and resilience though their associated microbial.
