    Abstract: One hundred days after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in Vietnam on 23 January, 270 cases were confirmed, with no deaths. We describe the control measures used by the government and their relationship with imported and domestically acquired case numbers, with the aim of identifying the measures associated with successful SARS-CoV-2 control. Methods Clinical and demographic data on the first 270 SARS-CoV-2 infected cases and the timing and nature of government control measures, including numbers of tests and quarantined individuals, were analyzed. Apple and Google mobility data provided proxies for population movement. Serial intervals were calculated from 33 infector-infectee pairs and used to estimate the proportion of presymptomatic transmission events and time-varying reproduction numbers. Results A national lockdown was implemented between 1 and 22 April. Around 200 000 people were quarantined and 266 122 reverse transcription polymerase chain reaction (RT-PCR) tests conducted. Population mobility decreased progressively before lockdown. In total, 60% (163/270) of cases were imported; 43% (89/208) of resolved infections remained asymptomatic for the duration of infection. The serial interval was 3.24 days, and 27.5% (95% confidence interval [CI], 15.7%-40.0%) of transmissions occurred presymptomatically. Limited transmission amounted to a maximum reproduction number of 1.15 (95% CI, .·37–2.·36). No community transmission has been detected since 15 April. Conclusions Vietnam has controlled SARS-CoV-2 spread through the early introduction of mass communication, meticulous contact tracing with strict quarantine, and international travel restrictions. The value of these interventions is supported by the high proportion of asymptomatic and imported cases, and evidence for substantial presymptomatic transmission.

    Abstract: - Đặt vấn đề: Nhiễm khuẩn nặng là tình trạng thường gặp tại các bệnh viện và dùng kháng sinh là điều bắt buộc. Meropenem được sử dụng phổ biến cho các nhiễm trùng này, dù có kết quả vi sinh hay chưa. Tuy nhiên, chưa có dữ liệu về hiệu quả và tính an toàn của các nhãn thuốc khác nhau. - Mục tiêu: So sánh tương đương hiệu quả điều trị và tính an toàn giữa Pimenem và Meronem (hàm lượng 0,5g và 1g) trong điều trị bệnh lý nhiễm trùng tại Bệnh viện Thống Nhất và Bệnh viện Đa khoa tỉnh Phú Yên. - Đối tượng và phương pháp nghiên cứu: Thử nghiệm lâm sàng có đối chứng, đa trung tâm: 121 bệnh nhân nhiễm trùng điều trị nội trú (viêm phổi mắc phải ở cộng đồng, viêm phổi bệnh viện, nhiễm trùng huyết và nhiễm trùng đường mật - ổ bụng) tại Bệnh viện Thống Nhất và Bệnh viện Đa khoa tỉnh Phú Yên trong khoảng thời gian từ 10/2019 đến 7/2022. Bệnh nhân thỏa tiêu chuẩn chọn bệnh và đồng thuận tham gia nghiên cứu sẽ được theo dõi trước và sau điều trị: các đặc điểm dịch tễ, lâm sàng và cận lâm sàng của bệnh nhân được ghi nhận; bệnh nhân được điều trị kháng sinh theo phác đồ của Bộ Y tế, sau đó đánh giá lại diễn tiến lâm sàng và kết quả vi sinh. - Kết quả: Độ tuổi trung bình của bệnh nhân là 70,6 ± 16,3 tuổi; nam giới chiếm tỉ lệ 56,2%. Nhiễm khuẩn đường hô hấp chiếm tỉ lệ cao nhất (47,1%) bao gồm viêm phổi bệnh viện (13,2%) và viêm phổi cộng đồng (33,9%), tiếp theo là nhiễm trùng huyết (33,1%). Tác nhân thường gặp nhất là E. coli (34,7%), kế đến là K. pneumoniae (24,5%). Tỉ lệ đề kháng meropenem cao nhất là 12,2% ở vi khuẩn K. pneumoniae. Không có sự khác biệt có ý nghĩa thống kê (p 〉 0,05) về kết quả điều trị giữa hai nhóm bệnh nhân sử dụng Pimenem và Meronem. Tác dụng phụ toàn thân thường gặp nhất là tăng tiểu cầu (4/121); không có sự khác biệt giữa hai nhóm Pimenem và Meronem. Giá thành của nhóm Pimenem thấp hơn đáng kể so với nhóm Meronem (p 〈 0,05). - Kết luận: Tỉ lệ viêm phổi chiếm tỉ lệ cao nhất trong số các căn nguyên nhiễm trùng. E. coli và K.pneumoniae là hai tác nhân được phân lập chủ yếu. Không có sự khác biệt về hiệu quả điều trị và tính an toàn của Pimenem và Meronem, trong khi xét về giá thành Pimenem thấp hơn đáng kể so với Meronem. Abstract - Background: Severe bacterial infections are common presentations in hospitals and antibiotic treatment is mandatory. Meropenem is one of the popular indicatons for treating infections, with or without microbiological results. However, there are insufficient data on the efficacy and safety between brands. - Objectives: Equivalence comparison of treatment efficacy and safety between Pimenem and Meronem (at doses 0.5 gram and 1 gram, respectively) in infectious - confirmed patients at Thong Nhat Hospital and Phu Yen Province General Hospital. - Methods: This is multicenter, controlled clinical trial including 121 inpatients with confirmed infection (i.e., community - acquired pneumonia, hospital - acquired pneumonia, sepsis and biliary - abdominal infections) at Thong Nhat Hospital and Phu Yen Province General Hospital, from October, 2019 to July, 2022. Patients who meet research criteria and consent to participate in the study will be evaluated before and after treatment: socio - demographic and clinical characteristics are recorded. Antibiotic use is followed the guideline of the Ministry of Health; then, final evaluation at the end of treatment course is performed. - Results: The mean age of patients was 70.6 ± 16.3 years old; male was accounted for 56.2%. Pneumonia was at the highest rate (47.1%), including hospital - acquired pneumonia (13.2%) and community - acquired pneumonia (33.9%), followed by sepsis (33.1%). The most isolated pathogens were E. coli (34.7%), followed by K. pneumoniae (24.5%). K. pneumoniae expressed the highest rate of meropenem resistance (12.2%) among pathogens. There was no statistical significance (p 〉 0.05) in the clinical outcomes between the two groups of patients using Pimenem and Meronem. The most common systemic drug - related adverse reaction was thrombocytosis (4/121); there was also no statistical significance in adverse reactions between Pimenem and Meronem groups. However, the cost of treatment course in Pimenem group was significantly lower than that of Meronem group (p 〈 0.05). - Conclusion: Pneumonia was at the highest rate among etiologies. E. coli and K. pneumoniae were two main isolated pathogens. There was no difference in the treatment efficacy and safety of Pimenem and Meronem, while in terms of total cost for treatment course, Pimenem was significantly lower than Meronem.

    Abstract: Biotic and abiotic factors control aboveground biomass (AGB) and the structure of forest ecosystems. This study analyses the variation of AGB and stand structure of evergreen broadleaved forests among six ecoregions of Vietnam. A data set of 173 1-ha plots from 52 locations in undisturbed old-growth forests was developed. The results indicate that basal area and AGB are closely correlated with annual precipitation, but not with annual temperature, evaporation or hours of sunshine. Basal area and AGB are positively correlated with trees 〉  30 cm DBH. Most areas surveyed (52.6%) in these old-growth forests had AGB of 100–200 Mg ha −1 ; 5.2% had AGB of 400–500 Mg ha −1 , and 0.6% had AGB of 〉  800 Mg ha −1 . Seventy percent of the areas surveyed had stand densities of 300–600 ind. ha −1 , and 64% had basal areas of 20–40 m 2 ha −1 . Precipitation is an important factor influencing the AGB of old-growth, evergreen broadleaved forests in Vietnam. Disturbances causing the loss of large-diameter trees (e.g., 〉  100 cm DBH) affects AGB but may not seriously affect stand density.

    Abstract: A patient with extensive burn injuries was admitted to the National Hospital of Burns in Hanoi, Vietnam, and diagnosed with fungal wound infection by histological examination of skin biopsy samples. Fusarium solani was isolated and identified by analysis of its morphological features and the sequence of the internal transcribed spacer region. The isolation showed in vitro resistant to fluconazole, voriconazole, itraconazole, amphotericin B, and caspofungin. Invasive fusariosis is difficult to treat due to its angioinvasive property and its lacking amenability to treatment with antifungal drugs. This infection is rare and has not been reported so far in Vietnam.

    Abstract: The current research proposes an innovative strategy for the facile preparation of magnetic activated carbon (MAC) from rosemary distillation residues (RDR). As a magnetic precursor, FeCl 3 was impregnated into RDR before KOH was added as an activating agent. One-pot pyrolysis was then conducted to produce zero-valent iron nanoparticles (14.4 wt%) embedded in the activated carbon matrix. Moreover, KOH activation yielded MAC with a large total pore volume of 0.27 cm 3 g −1 , a high specific surface area of 459 m 2 g −1 , and hierarchical porosity. With a large porous system and different polar functional groups, MAC was subsequently investigated for malachite green (MG) removal in aqueous media. At pH 6.0, the adsorption process was consistent with the pseudo-second-order kinetic model and the Langmuir isotherm, with a maximum adsorption capacity of 82.6 mg g −1 . Additionally, MAC demonstrated effective reusability after five consecutive cycles, when MG removal slightly decreased from 96.4 ± 0.6 to 91.8 ± 2.3%. Notably, MAC with a strong saturation magnetization of 18.4 emu g −1 could be conveniently recovered from treated media through magnetic fields. Overall, rosemary distillation residue-derived magnetic activated carbon can be a potential adsorbent for malachite green remediation thanks to its cost-effectiveness, eco-friendliness, and magnetic separability.

    Abstract: Background and Purpose: Burn injuries are prone to infection caused by bacteria, fungi, or other pathogens. Fungal wound infection usually has non-specific clinical symptoms.Nevertheless, in some cases, the fungal burden is so substantial that can easily be seen by the naked eyes, but this phenomenon has rarely been reported with Fusarium. Case report: A 53-year-old patient with severe burn injury was admitted to the intensive care unit of the National Hospital of Burn, Ha Noi, Vietnam. His wound was dressed with a traditional herbal product before the hospital admission. On the 5th day after the admission, some white patches suspected of fungal colonies appeared on burn lesions where the herbal medicine was placed. Histological examination (Periodic acidSchiff) and culture of biopsy samples taken from those lesions revealed fungus that was identified as Fusarium equiseti after analysis of the internal transcribed spacer and D1/D2 region of the large subunit of the 28S rDNA. The isolated strain showed susceptibility to voriconazole but resistance to fluconazole, itraconazole, caspofungin,and amphotericin B in vitro. The patient received aggressive treatment, including IV voriconazole (400 mg daily from day five); however, he could not recover. Conclusion: Fusarium should be suspected in burn patients with white patches on lesions. Antifungal susceptibility testing is important since multidrug resistance is common among Fusarium strains.
