The endothelial growth factor Angiopoietin-2 is an accurate prognostic biomarker in patients with acetaminophen-induced acute liver failure.

Background And Aims: Acetaminophen (APAP) overdose is the leading individual cause of acute liver failure (ALF) in the United States, with many patients rapidly progressing to hyperacute liver failure. While hepatocytes are the main target of APAP toxicity, endothelial cells (ECs) are also affected. However, the efficacy of an endothelial-specific biomarker to predict patient outcomes remains unknown.

HDAC6 inhibition upregulates endothelial SOD3 expression via Sp1 acetylation and attenuates angiotensin II-induced hypertension.

Extracellular superoxide dismutase (SOD3) plays an important role in maintaining vascular redox homeostasis by eliminating superoxides. The angiotensin II (AngII) peptide mediates vasoconstriction in part via reactive oxygen species (ROS) but has pathologic effects when elevated in adults. Histone deacetylase 6 (HDAC6) modulates the acetylation of non-histone substrates and is associated with hypertensive disorders.

Couple-based lifestyle intervention for minority prostate cancer survivors: a randomized feasibility trial.

Background: Black and Hispanic prostate cancer (PCa) survivors, who face a high burden of comorbid conditions and often engage in low levels of physical activity and healthy eating, remain significantly underrepresented in lifestyle intervention studies.

Purpose: Given the significance of spousal influence, we developed a culturally tailored lifestyle intervention for these survivors and their spouses and assessed its feasibility, acceptability, and impact on behavioral change.

Methods: Survivor-spouse couples were randomly assigned to an intervention group (n = 22), which received 12 health-coaching calls over 6 months, or a usual-care control group (n = 9).

Inhibition of HDAC6 elicits anticancer effects on head and neck cancer cells through Sp1/SOD3/MKP1 signaling axis to downregulate ERK phosphorylation.

Oxidative stress caused by reactive oxygen species (ROS) and superoxides is linked to various cancer-related biological events. Extracellular superoxide dismutase (SOD3), an antioxidant enzyme that removes superoxides, contributes to redox homeostasis and has the potential to regulate tumorigenesis. Histone deacetylase 6 (HDAC6), a major HDAC isoform responsible for mediating the deacetylation of non-histone protein substrates, also plays a role in cancer progression.

A new granite cave dwelling endemic species of the Cyrtodactylus intermedius group (Squamata: Gekkonidae) from Hon Son Island, Kien Giang Province, Vietnam.

During field work on Hon Son Island, we discovered a new species of the genus Cyrtodactylus inferred from genetic and morphological evidence. Phylogenetic analyses based on the mitochondrial gene ND2, delimit Cyrtodactylus borgattaorum sp. nov.

Corrigendum: Effectiveness of perindopril/amlodipine fixed-dose combination in the treatment of hypertension: a systematic review.

Translation and validation of the CLEO tool in Vietnamese to assess the significance of pharmacist interventions.

Background: There is currently no validated tool available for assessing the potential significance of pharmacist interventions in Vietnam.

Aim: This study aimed to translate the CLEO tool from French into Vietnamese, validate the Vietnamese version, and demonstrate its feasibility in daily practice.

Method: The CLEO tool was translated into Vietnamese (CLEO) using a 5-step process by bilingual experts.

Effectiveness of a Smartphone-Based Stress Management Program for Depression in Hospital Nurses During COVID-19 in Vietnam and Thailand: 2-Arm Parallel-Group Randomized Controlled Trial.

Background: During the COVID-19 pandemic, health care professionals experienced high levels of depression. However, extant research has not highlighted effective internet-based psychological interventions to improve the mental health in this population during the pandemic. It remains unclear whether self-guided, internet-based cognitive behavioral therapy (iCBT) programs are effective in improving the mental health of health care workers during the COVID-19 pandemic.

Multi-organ immune-related adverse events from immune checkpoint inhibitors and their downstream implications: a retrospective multicohort study.

Background: Understanding co-occurrence patterns and prognostic implications of immune-related adverse events is crucial for immunotherapy management. However, previous studies have been limited by sample size and generalisability. In this study, we leveraged a multi-institutional cohort and a population-level database to investigate co-occurrence patterns of and survival outcomes after multi-organ immune-related adverse events among recipients of immune checkpoint inhibitors.

Characterization of hyperactive mutations in the renal potassium channel ROMK uncovers unique effects on channel biogenesis and ion conductance.

Hypertension affects one billion people worldwide and is the most common risk factor for cardiovascular disease, yet a comprehensive picture of its underlying genetic factors is incomplete. Amongst regulators of blood pressure is the renal outer medullary potassium (ROMK) channel. While select ROMK mutants are prone to premature degradation and lead to disease, heterozygous carriers of some of these same alleles are protected from hypertension.

Pediatric Erythroid Sarcoma Diagnostically Confirmed by Identification of a Recurrent NFIA::CBFA2T3 Fusion.

Erythroid sarcoma (ES) is exceedingly rare in the pediatric population with only a handful of reports of de novo cases, mostly occurring in the central nervous system (CNS) or orbit. It is clinically and pathologically challenging and can masquerade as a nonhematopoietic small round blue cell tumor. Clinical presentation of ES without bone marrow involvement makes diagnosis particularly difficult.

De novo autoimmune connective tissue disease and mortality in patients treated with anti-programmed death receptor-1 and anti-programmed death-ligand 1 therapy: a population-level cohort study.

Using a population-level cohort analysis, our study demonstrates that, although rare, autoimmune cutaneous connective tissue diseases (AiCTDs) in the setting of immune checkpoint inhibitors (ICIs) are not associated with a greater risk of mortality and overall approach a statistically significant decrease in mortality when compared with patients treated with ICIs who do not experience cutaneous immune-related adverse events. These findings are significant and highly relevant to dermatologists and oncologists caring for ICI recipients as it adds to the limited information on development of cutaneous AiCTD following ICI administration, for which enhanced understanding is critical to improving the care for this challenging patient population.

Investigation of Urinary Metabolites of Organophosphate Esters in Hanoi, Vietnam: Assessment Exposure and Estimated Daily Intake.

In recent years, organophosphate esters (OPEs) have become one of the most common additives in various consumer products worldwide, therefore the exposure and impact of OPEs on human health are drawing a lot of attention. In this study, three metabolites of OPEs including bis(1,3-dichloro-2-propyl) phosphate (BDCIPP), diphenyl phosphate (DPhP) and diethyl phosphate (DEP) were investigated in first-morning void urine samples taken from a population (age range: 3-76 years old) in Hanoi, Vietnam. The most dominant urinary OPE metabolite was DEP with the geometric mean of specific gravity adjust (SG-adjusted) concentration were 1960 ng mL and detected frequency (DF) of 98%.

The p21 perinecrotic hepatocytes produce the chemokine CXCL14 after a severe acetaminophen overdose promoting hepatocyte injury and delaying regeneration.

Fifty percent of all acute liver failure (ALF) cases in the United States are due to acetaminophen (APAP) overdose. Assessment of canonical features of liver injury, such as plasma alanine aminotransferase activities are poor predictors of acute liver failure (ALF), suggesting the involvement of additional mechanisms independent of hepatocyte death. Previous work demonstrated a severe overdose of APAP results in impaired regeneration, the induction of senescence by p21, and increased mortality.

Outcomes and Costs of the Transition From a Paper-Based Immunization System to a Digital Immunization System in Vietnam: Mixed Methods Study.

Background: The electronic National Immunization Information System (NIIS) was introduced nationwide in Vietnam in 2017. Health workers were expected to use the NIIS alongside the legacy paper-based system. Starting in 2018, Hanoi and Son La provinces transitioned to paperless reporting.
