Genetic features of SARS-CoV-2 Alpha, Delta, and Omicron variants and their association with the clinical severity of COVID-19 in Vietnam.

Objectives: We investigated the genetic variations in the Alpha, Delta, and Omicron variants of SARS-CoV-2 and their association with clinical status and treatment outcomes in patients with COVID-19.

Methods: MiSeq was used to sequence the Alpha, Delta, and Omicron genomes, and MEGA 6.6 was used to define the nucleotide variations.

Distribution of human papillomavirus among Vietnamese women with cervical cancer and unusual genetic variability of HPV16.

HPV16, with typical mutations that differ in geographical distribution and carcinogenic potency, has implications for cervical cancer screening, clinical diagnosis, and treatment. DNASTAR and MEGA were used to identify HPV16 variants and construct a phylogenetic tree. The most prevalent HPV genotypes were HPV16 (63.

Lung abnormalities on computed tomography of Vietnamese patients with COVID-19 and the association with medical variables.

Objectives: Patients with COVID-19 may experience a lung injury without presenting clinical symptoms. Early detection of lung injury in patients with COVID-19 is required to enhance prediction and prevent severe progression.

Methods: Lung lesions in patients with COVID-19 were defined using the Fleischner Society terminology.

COVID-19 patients hospitalized after the fourth wave of the pandemic period in Vietnam: Clinical, laboratory, therapeutic features, and clinical outcomes.

Background/purpose: Despite having relatively high COVID-19 vaccine coverage in Vietnam, a fraction of COVID-19 patients required hospitalization due to severe symptoms. The purpose of this study was to describe the clinical, laboratory, complications, and treatment of COVID-19 patients hospitalized during the pandemic's fourth wave.

Methods: Genome sequencing was performed on COVID-19 patients.

Assessment of the distribution and ecological risks of heavy metals in coastal sediments in Vietnam's Mong Cai area.

Coastal sediments in the Mong Cai area were collected and analyzed for grain size, heavy metals, total organic carbon, and isotopes (Pb, Ra, δN, δC) to assess sediment quality. The most common sediments were fine sand in surface sediment, very fine sand in core C1, and very coarse and coarse silt in core C2. The total organic carbon was highest in C2 next to the surface and lowest in C1, with content levels of 1.

Identification of Trombiculid Chigger Mites Collected on Rodents from Southern Vietnam and Molecular Detection of Rickettsiaceae Pathogen.

Trombiculid "chigger" mites (Acari) are ectoparasites that feed blood on rodents and another animals. A crosssectional survey was conducted in 7 ecosystems of southern Vietnam from 2015 to 2016. Chigger mites were identified with morphological characteristics and assayed by polymerase chain reaction for detection of rickettsiaceae.

Value of multidetector computed tomography angiography before bronchial artery embolization in hemoptysis management and early recurrence prediction: a prospective study.

Background: Multidetector computed tomography (MDCT) angiography is a useful examination to detect the source of the bleeding in patients with hemoptysis. The aim of the study was to prospectively evaluate the role and clinical efficacy of MDCT angiography before bronchial artery embolization (BAE) for the management of hemoptysis, and to investigate the predictors of early recurrence.

Methods: It is a double-center study which included 57 hemoptysis patients undergoing MDCT angiography prior to BAE from August 2019 to July 2020.

Closed Reduction and Percutaneous Pinning for Supracondylar Fractures of Humerus in Vietnamese Children.

Background: Pediatric supracondylar humerus fracture (SHF) is a complicated injury which can result in severe sequela. Nowadays, closed reduction and percutaneous pinning (CRPP) is the most popular treatment.

Aim: This study had two aims (1) checking the result of treating pediatric SHF patients without neurovascular injury by CRPP under image intensifier, and (2) analysing neurovascular complications of CRPP in treating these patients.

Characteristics of high-risk HIV-positive IDUs in Vietnam: implications for future interventions.

The HIV epidemic in Vietnam is concentrated primarily among injecting drug users (IDUs). To prevent HIV-1 superinfection and to develop effective HIV prevention programs, data are needed to understand the characteristics of high-risk HIV-positive IDUs. In 2003 , we conducted a community-based cross-sectional study among predominately male, out-of-treatment IDUs, aged 18?45, in the Bac Ninh Province, Vietnam.

A cross-sectional study on prevalence of non-fatal drug overdose and associated risk characteristics among out-of-treatment injecting drug users in North Vietnam.

In a community-based cross-sectional survey among out-of-treatment male opiate injecting drug users (IDU) aged 18-45, data on non-fatal overdose were collected using a semi-structured questionnaire. From August to September 2003, 299 IDU were recruited in two districts of Bac Ninh, a semi-urban province in North Vietnam. Prevalence of lifetime and recent non-fatal overdose were 43.
