Fetal growth restriction adversely impacts trajectory of hippocampal neurodevelopment and function.

The last pregnancy trimester is critical for fetal brain development but is a vulnerable period if the pregnancy is compromised by fetal growth restriction (FGR). The impact of FGR on the maturational development of neuronal morphology is not known, however, studies in fetal sheep allow longitudinal analysis in a long gestation species. Here we compared hippocampal neuron dendritogenesis in FGR and control fetal sheep at three timepoints equivalent to the third trimester of pregnancy, complemented by magnetic resonance image for brain volume, and electrophysiology for synaptic function.

Vitamin B, B, and B Intakes and Risk of Gastric Cancer: Findings from a Case-Control Study.

Background/objectives: Gastric cancer is one of the leading malignancies worldwide. B vitamins play important roles in DNA synthesis and methylation because they are considered co-enzymes in one-carbon metabolism. There is inconclusive evidence regarding the associations between dietary vitamins B, B, and B with the risk of gastric cancer in different epidemiologic studies.

Factors associated with retention in Quitline counseling for smoking cessation among HIV-positive smokers receiving care at HIV outpatient clinics in Vietnam.

Background: Quitline counseling is an effective method for supporting smoking cessation, offering personalized and accessible assistance. Tobacco use is a significant public health issue among people living with HIV. In Vietnam, over 50% of men living with HIV use tobacco.

Dietary polyunsaturated fatty acids and gastric cancer.

Polyunsaturated fatty acids (PUFAs) are fatty acids, containing more than one double bond and have both anti-inflammatory properties and inhibit tumor progression effects as well as carcinogenic properties. There is inconclusive evidence regarding the effect of PUFA intake on gastric cancer in diverse populations. We, therefore, aimed to determine the association between PUFA intake and risk of gastric cancer in a hospital-based case-control study comprising 1182 incident cases of gastric cancer and 2965 controls in Vietnam.

Development of a loop-mediated isothermal amplification method for the rapid detection of Clostridium botulinum serotypes E and F.

Background: Botulinum neurotoxin serotypes E and F (BoNT/E and BoNT/F) produced by the bacteria Clostridium botulinum (C. botulinum) found in a wide variety of foods cause poisoning in humans with high mortality rates. Mouse bioassays (MBAs), the gold standard method for BoNT detection, have a low detection limit; however, require experienced personnel and take a long time to obtain results.

Factors Affecting Cancer Mortality in Young Adults: Findings from a Prospective Cohort Study.

Background/objectives: Cancer incidence in young adults or those aged 15-49 years old has increased during the past decade. Knowledge about the risk factors for cancer-related deaths in young adults is limited, particularly in low- and middle-income countries (LMICs).

Methods: This analysis was based on the Hanoi Prospective Cohort Study, an ongoing study of 39,401 participants aged 15 or older in Northern Vietnam in the 2007-2019 period.

Rapid oxygen titration following cardiopulmonary resuscitation mitigates cerebral overperfusion and striatal mitochondrial dysfunction in asphyxiated newborn lambs.

Asphyxiated neonates must have oxygenation rapidly restored to limit ongoing hypoxic-ischemic injury. However, the effects of transient hyperoxia after return of spontaneous circulation (ROSC) are poorly understood. We randomly allocated acutely asphyxiated, near-term lambs to cardiopulmonary resuscitation in 100% oxygen ("standard oxygen", n = 8) or air (n = 7) until 5 minutes after ROSC, or to resuscitation in 100% oxygen immediately weaned to air upon ROSC ("rapid-wean", n = 7).

Vitamin B12 Intake and Cancer Risk: Findings from a Case-Control Study in Vietnam.

There is inconclusive evidence on the role of dietary intake of vitamin B in cancer. We evaluated the association between vitamin B intake and cancer risk in a hospital-based case-control study, comprising 3,758 cancer cases and 2,995 controls in Vietnam. Vitamin B intake was derived from the validated food frequency questionnaire.

A Systems Thinking Approach to Tackle Antimicrobial Resistance.

Antimicrobial resistance (AMR) poses a significant global health threat. Due to its complexity, holistic approaches focusing on the interconnected factors influencing AMR across One Health domains are necessary. This study adopts system dynamics with extensive stakeholder engagement to unravel feedback processes between factors driving AMR.

A U-shaped association between selenium intake and cancer risk.

While selenium is a cofactor of several antioxidant enzymes against cancer and is essential for human health, its excess intake may also be harmful. Though a safe intake of selenium has recently been recommended, it is not well understood in the Asian population. We aimed to determine the association between dietary intake of selenium and cancer risk in a case-control study of 3758 incident cancer cases (i.

Waterpipe Tobacco Smoking and Risk of Cancer Mortality.

Importance: There has been an increasing trend of using noncigarette products, including waterpipe tobacco (WTP), worldwide. While cigarette smoking is a well-established risk factor for numerous cancers, little is known about the association between WTP smoking and cancer mortality.

Objective: To assess the association between WTP smoking and risk of cancer mortality in Vietnam.

The synergistic effects of mechanical ventilation and intrauterine inflammation on cerebral inflammation in preterm fetal sheep.

Background: Intrauterine inflammation and the requirement for mechanical ventilation independently increase the risk of perinatal brain injury and adverse neurodevelopmental outcomes. We aimed to investigate the effects of mechanical ventilation for 24 h, with and without prior exposure to intrauterine inflammation, on markers of brain inflammation and injury in the preterm sheep brain.

Methods: Chronically instrumented fetal sheep at ~115 days of gestation were randomly allocated to receive a single intratracheal dose of 1 mg lipopolysaccharide (LPS) or isovolumetric saline, then further randomly allocated 1 h after to receive mechanical ventilation with room air or no mechanical ventilation (unventilated control + saline [UVC,  = 7]; mechanical ventilation + saline [VENT,  = 8], unventilated control + intratracheal LPS [UVC + LPS,  = 7]; ventilation + intratracheal LPS [VENT + LPS,  = 7]).

Pembrolizumab-induced Stevens-Johnson syndrome/Toxic Epidermal Necrolysis in a Vietnamese patient with nonsmall-cell lung cancer.

Chemoimmunotherapy is an effective therapy for an individual with nonsmall-cell lung cancer (NSCLC) without anaplastic lymphoma kinase or epidermal growth factor receptor mutations. However, it can also be related to adverse cutaneous reactions such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) with high morbidities and mortality rates. We present a case of a 65-year-old male with NSCLC who underwent first-line chemotherapy with paclitaxel, carboplatin, and pembrolizumab, which was later followed by a second cycle of the same therapies.

Early administration of umbilical cord blood cells following brief high tidal volume ventilation in preterm sheep: a cautionary tale.

Background: Umbilical cord blood (UCB) cells are a promising treatment for preterm brain injury. Access to allogeneic sources of UCB cells offer the potential for early administration to optimise their therapeutic capacities. As preterm infants often require ventilatory support, which can contribute to preterm brain injury, we investigated the efficacy of early UCB cell administration following ventilation to reduce white matter inflammation and injury.

The Temporal Relationship between Blood-Brain Barrier Integrity and Microglial Response following Neonatal Hypoxia Ischemia.

Blood-brain barrier (BBB) dysfunction and neuroinflammation are key mechanisms of brain injury. We performed a time-course study following neonatal hypoxia-ischemia (HI) to characterize these events. HI brain injury was induced in postnatal day 10 rats by single carotid artery ligation followed by hypoxia (8% oxygen, 90 min).

Changing global epidemiology of chronic hepatitis C virus-related outcomes from 2010 to 2019: cirrhosis is the growing burden of hepatitis C virus-related disease.

Background: Chronic infection with hepatitis C virus (HCV) has a long-term impact on hepatic consequences. A comprehensive evaluation of the global burden of HCV-related health outcomes can help to develop a global HCV prevention and treatment program.

Methods: We used the 2019 Global Burden of Disease (GBD) Study to comprehensively investigate burden and temporal trends in incidence, mortality and disability-adjusted life-years (DALYs) of HCV-related diseases, including liver cancer and cirrhosis and other liver diseases across 264 countries and territories from 2010 to 2019.

Phenotype of early-onset fetal growth restriction in sheep.

Introduction: Fetal growth restriction (FGR) is a common pregnancy complication, caused by placental insufficiency, with serious adverse consequences for development and postnatal wellbeing. There are no antenatal treatments to improve growth or organ development in FGR, and animal models are essential to mimic the physiological adaptations in FGR and to assess potential interventions. This study aimed to identify the temporal nature of reduced developmental trajectory in fetuses with FGR, and to examine the effects of common factors that may mediate differential growth such as glucocorticoid treatment.

Low-Carbohydrate Diet Score and Risk of Hepatocellular Carcinoma: Findings from a Prospective Cohort Study.

Unlabelled: Limited data are reported on the association between low-carbohydrate diet (LCD) score, a comprehensive measure of dietary pattern according to sources of carbohydrate, fat, and protein, and risk of hepatocellular carcinoma (HCC). We evaluated this score with HCC risk in the Singapore Chinese Health Study, a prospective cohort of 63,275 middle-aged and elderly Chinese living in Singapore and recruited during 1993-1998 period. LCD scores were derived from the semi-quantitative food frequency questionnaire at baseline.

Immunosuppressive Cyclotides: A Promising Approach for Treating Autoimmune Diseases.

The immune system maintains constant surveillance to prevent the infiltration of both endogenous and exogenous threats into host organisms. The process is regulated by effector immune cells that combat external pathogens and regulatory immune cells that inhibit excessive internal body inflammation, ultimately establishing a state of homeostasis within the body. Disruption to this process could lead to autoimmunity, which is often associated with the malfunction of both T cells and B cells with T cells playing a more major role.

Depression and associated factors among HIV-positive smokers receiving care at HIV outpatient clinics in Vietnam: a cross-sectional analysis.

Objectives: To assess the prevalence of depressive symptoms and associated factors among people living with HIV (PLWH) who were current cigarette smokers and receiving treatment at HIV outpatient clinics (OPCs) in Vietnam.

Design: A cross-sectional survey of smokers living with HIV.

Setting: The study was carried out in 13 HIV OPCs located in Ha Noi, Vietnam.

Social support among English learners with disabilities and other adolescents.

Introduction: Social support is important for many youth but may be particularly important for English learners (ELs) with disabilities, a population that has historically faced barriers accessing resources to meet their educational needs. The current study investigates social support from parents, peers, teachers, and schools in a nationally representative sample of adolescents.

Method: Data from the National Longitudinal Transition Study 2012 was used to evaluate potential group differences in social support among participants that included ELs with (n = 440) and without disabilities (n = 100) and non-ELs with (n = 4890) and without disabilities (n = 1090).

Neuroprotective effects of maternal melatonin administration in early-onset placental insufficiency and fetal growth restriction.

Background: Early-onset fetal growth restriction (FGR) is associated with adverse outcomes. We hypothesised that maternal melatonin administration will improve fetal brain structure in FGR.

Methods: Surgery was performed on twin-bearing ewes at 88 days (0.

Tryptophan intake and pancreatic cancer: findings from a case-control study.

Background: Pancreatic cancer is a leading cause of cancer-related death worldwide. Tryptophan plays a vital role in cell growth and maintenance as a building block of protein and coordination of organismal responses to environmental and dietary cues. Animal model study showed that dietary tryptophan improved treatment response in those who received chemotherapy or immune checkpoint inhibitors.
