We determined the impact of moderate maternal nutrient restriction (MNR) in guinea pigs with fetal growth restriction (FGR) on offspring body and organ weights, hypothesizing that FGR-MNR animals will show catch-up growth, but with organ-specific differences. Guinea pig sows were fed ad libitum (Control) or 70% of the control diet from 4 week`s pre-conception, switching to 90% at mid-pregnancy (MNR). Control newborns >95g (appropriate for gestational age or AGA, N=37) and MNR newborns <85g (FGR, N=37) were monitored until neonatal (~25 days) or adult (~110 days) necropsy...

Purpose: Atrioventricular nodal reentry tachycardia (AVNRT) is less common in pediatric patients than in adult patients. Thus, data for pediatric AVNRT patients are insufficient. Hence, we aimed to analyze the patient characteristics, treatment, and any recurrences in pediatric AVNRT patients. Methods: We reviewed the records of 50 pediatric AVNRT patients who had undergone radiofrequency catheter ablation (RFCA) between January 1998 and December 2016 at a single regional center...

INTRODUCTION AND OBJECTIVES: Hypertension causes subclinical changes in left ventricular structure and function, namely diastolic dysfunction. Diastolic dysfunction is a predictor of heart failure, being involved in the association between hypertension and heart failure with preserved ejection fraction. We aimed to determine whether patients with prehypertension have early changes in diastolic function in a large community-based cohort of asymptomatic adults. METHODS: A cross-sectional evaluation was performed of a community-based cohort consisting of 925 adults, aged 45 years or older, without known cardiovascular disease...

BACKGROUND: The noninvasive assessment of superior vena cava (SVC), crista terminalis (CT), and the right atrial appendage (RAA) has clinical implications in determining the right atrium (RA) pressure in adult patients in whom the inferior vena cava cannot be imaged, in planning electrophysiological procedures and for evaluation of thrombi in RA/RAA. It is difficult to image these structures using standard two-dimensional transthoracic echocardiography (2DTTE), but the right parasternal approach has shown promise in the very few studies published so far...

The mediastinal serous cavity is a normal anatomic space in the caudal mediastinum. Aims of this anatomic and case series study were to describe the signs of pathologic expansion of the mediastinal serous cavity observed during computed tomography (CT), review the underlying anatomy, perform a literature review, and evaluate the medical records of several dogs with mediastinal serous cavity empyema (paraesophageal empyema). The mesothelial lined mediastinal serous cavity is a cranial extension of the omental bursa, separated from the peritoneal cavity by the diaphragm, in the dorsal part of the caudal mediastinum, to the right of the esophagus, between the heart base and diaphragm...

BACKGROUND: The aim of this study was to examine the association between myocardial strain and arterial thickness and stiffness in young adults. Increased common carotid artery intima media thickness and peripheral arterial stiffness are known to precede coronary artery disease and cardiovascular (CV) events such as myocardial infarction and congestive heart failure. However, subclinical cardiac dysfunction can be detected in high-risk adults by myocardial strain echocardiography. The authors hypothesized that increased carotid artery intima media thickness would be associated with abnormal myocardial strain in young subjects who had obesity and type 2 diabetes mellitus...

Background -The causal role of high density lipoprotein (HDL) cholesterol in cardioprotection has been questioned by genetic and randomized studies. Novel measures that relate to HDL function may contribute new information to prediction of cardiovascular risk. Apolipoprotein C-III (apoC-III) is a key regulator of lipoprotein metabolism. We investigated whether subspecies of HDL defined by apoC-III are associated with coronary heart disease (CHD). Methods -We used immuno-affinity chromatography to measure the apoA-I concentrations of HDL that contains and lacks apoC-III in two prospective studies of adults free of CHD...

BACKGROUND & AIMS: Alagille syndrome is a genetic disorder characterized by cholestasis, ocular abnormalities, characteristic facial features, heart defects, and vertebral malformations. Most cases are associated with mutations in JAGGED1 (JAG1), which encodes a Notch ligand, although it is not clear how these contribute to disease development. We aimed to develop a mouse model of Alagille syndrome to elucidate these mechanisms. METHODS: Mice with a missense mutation (H268Q) in Jag1 (Jag1(+)/(Ndr) mice) were outbred to a C3H/C57bl6 background to generate a mouse model for Alagille syndrome (Jag1(Ndr/Ndr) mice)...

RATIONALE: Lymph node is a preferred site for extrapulmonary tuberculosis (TB). In the thorax, mediastinal tuberculous lymph nodes can erode adjacent structures such as heart, aorta, and esophagus, forming fistula, and causing fatal consequences. However, tuberculous bronchonodal fistula as a complication of lymph node TB in adults is rarely known in terms of imaging or clinical findings. Here, a case of isolated tuberculous bronchonodal fistula appearing as the first presentation of TB in a 74-year-old male with systemic lupus erythematosus (SLE) is reported...

OBJECTIVE: Relatively little is known about outcomes after disposition among syncope patients assigned various diagnostic categories during emergency department (ED) evaluation. We sought to measure the outcomes among these groups within 30 days of the initial ED visit. METHODS: We prospectively enrolled adult syncope patients at six EDs and excluded patients with pre-syncope, persistent mental status changes, intoxication, seizure, and major trauma. Patient characteristics, ED management, diagnostic impression (presumed vasovagal, orthostatic, cardiac, or other/unknown) at the end of the ED visit and physicians' confidence in assigning the etiology were collected...

BACKGROUND/AIMS: High-fat diet (HFD) causes cardiac electrical remodeling and increases the risk of ventricular arrhythmias. Aloe-emodin (AE) is an anthraquinone component isolated from rhubarb and has a similar chemical structure with emodin. The protective effect of emodin against cardiac diseases has been reported in the literature. However, the cardioprotective property of AE is still unknown. The present study investigated the effect of AE on HFD-induced QT prolongation in rats. METHODS: Adult male Wistar rats were randomly divided into three groups: control, HFD, and AE-treatment groups...

BACKGROUND: Neurodevelopmental impairments have frequently been described in children and adolescents with dextro-transposition of the great arteries (d-TGA). The arterial switch operation (ASO) to correct d-TGA has been used for more than 30 years, and more than 90% of these patients now reach adulthood. However, very little is known about their long-term functional outcomes. The present study investigated neurocognitive outcomes and the prevalence of psychiatric disorders in adults with d-TGA corrected by ASO...

Most mid-life adults have at least one chronic medical condition (CMC) and are at risk for developing additional CMCs. Stressors specific to this life stage may contribute to CMC development by hindering healthy behaviors. The goal of this study was to compare sources and intensity of distress, as they relate to health behaviors, between mid-life and non-mid-life adults with CMCs. We utilized a mixed-methods approach by analyzing quantitative self-report measures of psychiatric symptoms and psychological well-being, with in-depth, semi-structured qualitative interviews to identify sources of stress in three cohorts of patients with CMCs (heart failure, type 2 diabetes, and coronary artery disease)...
