Etiologic and demographic characteristics of syncope in children and adolescents: a nationwide population-based study in Korea.

Background: Syncope is common among children and adolescents. Although it is most commonly caused by vasovagal syncope, it can also be due to undiagnosed, potentially serious, or even life-threatening conditions. We aimed to investigate the distribution of subsequent sinister diagnoses, such as heart disease (HD) and epilepsy, and analyze their demographic characteristics in children presenting with syncope.

CD137+ tumor infiltrating lymphocytes predicts ovarian cancer survival.

Objective: Ovarian cancer (OC) is the leading cause of death from gynecologic malignancy in the United States, and biomarkers of patient outcomes are limited. Data using immunohistochemical (IHC) analysis are mixed regarding whether and which tumor infiltrating lymphocytes (TILs) impact survival, and IHC does not adequately quantify rare cell populations, including CD137+ (4-1BB) tumor-reactive TILs. Our study investigates if a higher percentage of CD3+ CD137+ TILs is associated with improved overall survival (OS) in OC.

Ginsenoside-Re inhibits experimental autoimmune encephalomyelitis as a mouse model of multiple sclerosis by downregulating TLR4/MyD88/NF-κB signaling pathways.

Inhibition of lysophosphatidic acid receptor 1-3 deteriorates experimental autoimmune encephalomyelitis by inducing oxidative stress.

Background: Lysophosphatidic acid receptors (LPARs) are G-protein-coupled receptors involved in many physiological functions in the central nervous system. However, the role of the LPARs in multiple sclerosis (MS) has not been clearly defined yet.

Methods: Here, we investigated the roles of LPARs in myelin oligodendrocyte glycoprotein peptides-induced experimental autoimmune encephalomyelitis (EAE), an animal model of MS.

Hypertrophic Cardiomyopathy in Infants from the Perspective of Cardiomyocyte Maturation.

Hypertrophic cardiomyopathy (HCM) is characterized by ventricular wall hypertrophy with diastolic dysfunction. Pediatric HCM is distinguished from the adult in many aspects. Most children with HCM do not present clinically until the adolescent period, even when they are born with genetic mutations.

Rg3-enriched Korean Red Ginseng extract inhibits blood-brain barrier disruption in an animal model of multiple sclerosis by modulating expression of NADPH oxidase 2 and 4.

Background: Multiple sclerosis (MS) and its animal model, the experimental autoimmune encephalomyelitis (EAE), are primarily characterized as dysfunction of the blood-brain barrier (BBB). Ginsenoside-Rg3-enriched Korean Red Ginseng extract (Rg3-KRGE) is known to exert neuroprotective, anti-inflammatory, and anti-oxidative effects on neurological disorders. However, effects of Rg3-KRGE in EAE remain unclear.

Pregnant and hungry: addressing food insecurity in pregnant women during the COVID-19 pandemic in the United States.

Food insecurity is a major social determinant of health affecting more than 10% of Americans. Social determinants of health are increasingly recognized as a driving force of health inequities. It is well established that food insecurity leads to adverse health outcomes outside of pregnancy, such as obesity, hypertension, diabetes mellitus, and mental health problems.

Ginseng gintonin attenuates the disruptions of brain microvascular permeability and microvascular endothelium junctional proteins in an APPswe/PSEN-1 double-transgenic mouse model of Αlzheimer's disease.

It has been previously indicated that gintonin, which is a novel exogenous ginseng-derived lysophosphatidic acid (LPA) receptor ligand, restores memory dysfunctions in an APPswe/PSEN-1 double-transgenic mouse model of Alzheimer's disease (AD Tg mice) by attenuating β-amyloid plaque deposition, recovering cholinergic dysfunctions and upregulating hippocampal neurogenesis in the cortex and hippocampus. Although β-amyloid plaque depositions in AD is accompanied with disruptions of brain microvessels, including the brain-blood barrier (BBB), it is unknown whether gintonin exerts protective effects on brain microvascular dysfunctions in AD Tg mice. In the present study, the effects of gintonin-enriched fraction (GEF) on the changes in β-amyloid plaque depositions, brain permeability of Evans blue, and microvascular junctional proteins were investigated in AD Tg mice.

Lymphadenectomy is associated with an increased risk of postoperative venous thromboembolism in early stage endometrial cancer.

Objectives: In patients undergoing surgery for early stage endometrial cancer, we sought to evaluate the effect of lymphadenectomy (LND), as well as surgical route, on the risk of postoperative venous thromboembolism (VTE).

Methods: The Surveillance, Epidemiology, and End Results cancer registries (2000-2013) linked to Medicare claims follow up from 1999 to 2014 was accessed to identify those with stage I-II endometrioid endometrial cancer who underwent hysterectomy. Performance of LND, 90-day incidence of postoperative VTE, open vs minimally invasive surgery (MIS), demographics, comorbidities, grade, and stage were collected.
