Early and mid-term outcomes of transcatheter closure of perimembranous ventricular septal defects using double-disc occluders.

Introduction: Ventricular septal defect (VSD) is a common congenital heart disease (CHD), accounting for 20-30% of all CHD cases. While surgical closure has been the gold standard for treatment, transcatheter closure has emerged as a less invasive alternative, particularly for perimembranous VSDs. This study aimed to evaluate the early and mid-term outcomes of transcatheter closure using a double-disc occluder device in a single-center Vietnamese cohort.

Avoidance of healthcare service use and correlates among HIV-positive patients in Vietnam: a cross-sectional study.

Objective: The prevention of HIV/AIDS is not making sufficient progress. The slow reduction of HIV/AIDS infections needs to prioritise hesitancy towards service utilisation, including treatment duration, social support and social stigma. This study investigates HIV-positive patients' avoidance of healthcare services and its correlates.

Nutritional status of Vietnamese infants assessed by Fenton growth chart and related factors: A cross-sectional study.

Introduction: Tetanus vaccine coverage in Vietnam has been declining in recent years due to a rapid population growth rate, shrinking budget, and inefficient resource mobilization strategy. This study examined the uptake, demand, and willingness to pay (WTP) for tetanus vaccines in Vietnamese women of reproductive age as well as determined associated factors and assessed the feasibility of the long-term tetanus vaccine resource mobilization scheme.

Methods: Cross-sectional data were obtained on 807 women of childbearing age in Hanoi, Vietnam in 2016.

The prevalence of self-reported anxiety, depression, and associated factors among Hanoi Medical University's students during the first wave of COVID-19 pandemic.

Background: Medical students are known to have higher levels of these issues than the general population but in Vietnam the effects of the pandemic on medical student mental health was not documented.

Objectives: To estimate the prevalence and identify factors associated with self-reported anxiety disorder, depression, and perception of worsening mental health among Vietnamese medical students during the COVID-19 pandemic.

Method: A cross-sectional study was conducted from April 7th to 29th, 2020.

Heavy metals in surface sediments of the intertidal Thai Binh Coast, Gulf of Tonkin, East Sea, Vietnam: distribution, accumulation, and contamination assessment.

Heavy metals contamination in sediments may endanger ecosystems and human health via the food chain. In fact, there is little to no understanding about heavy metal accumulation in surface sediment of one of the most economically important marine bodies for Vietnam, the Thai Binh Coast, where five large rivers co-discharge into the Gulf of Tonkin. Twenty-seven surface sediment samples were collected from the intertidal regions and analyzed for: arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), and zinc (Zn) using inductively coupled plasma mass spectroscopy (ICP-MS).

Tobacco smoking and nicotine dependence among patients with respiratory diseases in Vietnam: Status and correlated factors.

Introduction: Understanding nicotine dependence can support clinicians in enhancing the effectiveness of treatments for respiratory patients. Our research aimed to assess the severity of nicotine dependence among patients with respiratory diseases in Vietnam and accordingly suggest potential interventions for tobacco cessation.

Methods: A cross-sectional study was conducted at the Respiratory center of Bach Mai Hospital, Hanoi, for two months of 2016 (October and November).

Depressive symptoms are associated with immunological failure among HIV-positive patients in Vietnam.

As the lives of people living with HIV (PLWH) become increasingly normalized, more focus is being given to the associated comorbidities of HIV, including those related to mental health such as depression. This study aims to evaluate the correlation between depressive symptoms and HIV outcomes in Vietnam through the measurement of CD4 cell count. A mixed design was utilized, in which both a longitudinal assessment of CD4 cell counts and a cross-sectional survey of depressive symptoms were conducted on 481 patients in the Bach Mai and Ha Dong HIV clinics (Hanoi, Vietnam).

Income Inequalities in Hepatitis B Vaccination and Willingness to Pay Among Women of Reproductive Age in Hanoi, Vietnam.

Background: Hepatitis B virus (HBV) infection is endemic in Vietnam and can be transmitted from mother to child. Vaccination of women of reproductive age (WRA) can reduce this transmission. Because adult HBV vaccination in Vietnam follows a fee-for-service model, research is needed to determine the effect of household income on willingness to pay (WTP) to ensure equitable access to the vaccine.

Predicting the environmental suitability for onchocerciasis in Africa as an aid to elimination planning.

Recent evidence suggests that, in some foci, elimination of onchocerciasis from Africa may be feasible with mass drug administration (MDA) of ivermectin. To achieve continental elimination of transmission, mapping surveys will need to be conducted across all implementation units (IUs) for which endemicity status is currently unknown. Using boosted regression tree models with optimised hyperparameter selection, we estimated environmental suitability for onchocerciasis at the 5 × 5-km resolution across Africa.

A qualitative assessment in acceptability and barriers to use pre-exposure prophylaxis (PrEP) among men who have sex with men: implications for service delivery in Vietnam.

Background: HIV Pre-exposure prophylaxis (PrEP) is being considered for implementation among MSM nationwide in Vietnam. However, there may be concerns about potential obstacles for PrEP adherence among Vietnamese MSM. This study aims to assess the acceptability to use PrEP, potential barriers and facilitators, and the preferences for PrEP service accessibility and delivery among Vietnamese MSM.

Estimating global injuries morbidity and mortality: methods and data used in the Global Burden of Disease 2017 study.

Background: While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria.

Methods: In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation.

Investigation on the Epoxidation of Piperitenone, and Structure-activity Relationships of Piperitenone Oxide for Differentiation-inducing Activity.

Piperitenone oxide, a major chemical constituent of the essential oil of spearmint, Mentha spicata, induces differentiation in human colon cancer RCM-1 cells. In this study, piperitenone oxide and trans-piperitenone dioxide were prepared as racemic forms by epoxidation of piperitenone. The relative configuration between two epoxides in piperitenone dioxide was determined to be trans by H NMR analysis and nuclear Overhauser effect spectroscopy (NOESY) in conjunction with density functional theory (DFT) calculations.

The Status of First Aid and Its Associations with Health Outcomes among Patients with Traffic Accidents in Urban Areas of Vietnam.
