Efficacy of High Flow Nasal Cannula in the Treatment of Patients with COVID-19 with Acute Respiratory Distress Syndrome: Results of Single Centre Study in Vietnam.

Introduction: Most hospitalized patients required invasive or non-invasive ventilation and High Flow Nasal Cannula (HFNC). Therefore, this study was conducted to describe the characteristics of patients with severe Coronavirus Disease-2019 (COVID-19) treated by HFNC and its effectiveness for reducing the rate of intubated-mechanical ventilation in the Intensive Care Unit (ICU) of Phu Chanh COVID-19 Department-Binh Duong General Hospital.

Methods: It was a cross-sectional and descriptive study.

Predictive Factors of Mortality in Patients with Severe COVID-19 Treated in the Intensive Care Unit: A Single-Center Study in Vietnam.

Introduction: The fourth outbreak of COVID-19 with the delta variant in Vietnam was very fierce due to the limited availability of vaccines and the lack of healthcare resources. During that period, the high mortality of patients with severe and critical COVID-19 caused many concerns for the health system, especially the intensive care units. This study aimed to analyze the predictive factors of death and survival in patients with severe and critical COVID-19.

Guillain-Barré Syndrome due to COVID-19 Vero Cell Vaccination Associated with Concomitant COVID-19 Infection-induced ARDS and Treated Successfully by Therapeutic Plasma Exchange: A First Case Report from Vietnam.

Post-vaccination adverse reactions have been reported with varying symptoms and severity owing to research and production time pressures during the coronavirus disease 2019 (COVID-19) pandemic. In this article, we report a rare case of Guillain-Barré syndrome (GBS) in a patient with COVID-19 with acute respiratory distress syndrome (ARDS) after receiving Sinopharm's Vero Cell vaccine (China). The patient who was initially negative for COVID-19 was diagnosed with GBS based on paralysis that developed from the lower extremities to the upper extremities, as confirmed by cytoalbuminologic dissociation in the cerebrospinal fluid.

Stigmastane-type steroid saponins from the leaves of and their -glucosidase and xanthine oxidase inhibitory activities.

Two new vernonioside K () and vernonioside L () and four known Δ stigmastane-type steroidal saponins-vernonioside B2 (), vernoniacum B (), vernonioside B1 (), and vernoamyoside A ()-were isolated from the leaves of . Their structures were determined by comprehensive spectroscopic analysis with one-dimensional nuclear magnetic resonance, two-dimensional nuclear magnetic resonance, and high-resolution mass spectrometry. All isolated compounds (-) were evaluated to determine their inhibitory effects on -glucosidase and xanthine oxidase.

Bradycardia unresponded to atropin testing was successfully treated with therapeutic plasma exchange in a patient with severe COVID-19 complicated by Guillain-Barré syndrome: A case report.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been an alarming situation worldwide for the past 2 years. The symptoms of coronavirus disease 2019 (COVID-19) are not only confined to the respiratory system but also affect a multitude of organ systems. Bradycardia associated with Guillain-Barré syndrome (GBS) is a rare autonomic and peripheral neurological complication of COVID-19.

Surface-plasmon-enhanced ultraviolet emission of Au-decorated ZnO structures for gas sensing and photocatalytic devices.

Pure and Au-decorated sub-micrometer ZnO spheres were successfully grown on glass substrates by simple chemical bath deposition and photoreduction methods. The analysis of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images, energy-dispersive X-ray spectroscopy (EDS), UV-vis absorption, and photoluminescence (PL) spectra results were used to verify the incorporation of plasmonic Au nanoparticles (NPs) on the ZnO film. Time-resolved photoluminescence (TRPL) spectra indicated that a surface plasmonic effect exists with a fast rate of charge transfer from Au nanoparticles to the sub-micrometer ZnO sphere, which suggested the strong possibility of the use of the material for the design of efficient catalytic devices.

Estimates of meteorological variability in association with dengue cases in a coastal city in northern Vietnam: an ecological study.

Background: Dengue fever (DF) is a vector-borne disease that is sensitive to weather and climate variability. To date, however, this relationship in coastal northern Vietnam has not been well documented.

Objectives: This paper aims to examine the associations between meteorological variables and dengue incidence in Haiphong, Vietnam, over the period 2008-2012.
