Symptomatic Valvular and Subvalvular Stenosis: A Case Report.

Aortic stenosis is a common valvular disease that is expected to become more prevalent with the aging population. It is often undiagnosed in socioeconomically deprived groups. Diagnosis relies on echocardiography, and additional imaging techniques such as cardiac computed tomography (CCT) and cardiovascular magnetic resonance (CMR) are increasingly used.

Severe Mitral Valve Regurgitation Secondary to Fulminant Myocarditis in the Setting of a Lupus Flare.

Systemic Lupus Erythematosus represents a chronic autoimmune disorder characterized by multiorgan involvement. Lupus myocarditis is a rare presentation of one of the cardiac complications of lupus with an incidence of 3-9%. It usually presents with non-specific symptoms such as dyspnea, orthopnea, chest pain, pedal edema, fever, diaphoresis, paroxysmal nocturnal dyspnea, nausea, vomiting, or palpitations.

Echocardiographic Features of an Evolving Periaortic Valvular Abscess in a Patient with Staphylococcus Epidermidis Prosthetic Valve Endocarditis.

Prosthetic valve endocarditis is a serious complication following valve replacement surgery, with the development of aortic root abscess being a catastrophic manifestation. We present a case of a 71-year-old female with a bioprosthetic aortic valve who presented with shortness of breath. Echocardiographic findings revealed vegetation on the prosthetic aortic valve with a periaortic, annular abscess.

Contained Left Ventricular Free Wall Rupture Following a Silent Myocardial Infarction.

A left ventricular pseudoaneurysm (LVP) is defined as an outpouching contained by the surrounding pericardium. Clinical presentation is often unspecific with patients presenting with chest pain, dyspnea, symptoms consistent with heart failure, and post-myocardial infarction. Cardiac magnetic resonance imaging represents an important tool for differentiating a pseudoaneurysm from a true aneurysm.

Enacting inclusive science: Culturally responsive higher education practices in science, technology, engineering, mathematics, and medicine (STEMM).

Novel approaches in higher education are needed to reverse underrepresentation of racial/ethnic groups in science, technology, engineering, mathematics, and medicine (STEMM). Building on theoretical frameworks for practice in diverse learning environments, this study provides evidence for Inclusive Science as a conceptual model that reflects initiatives intended to diversify biomedical research training for undergraduates. Using multiple case study design and cross-case analysis, we analyzed data from 10 higher education sites that were awarded the Building Infrastructure Leading to Diversity (BUILD) grant funded by the National Institutes of Health (NIH).

Left Ventricular Non-compaction Cardiomyopathy: A Case Report and Literature Review.

Left Ventricular Non-Compaction Cardiomyopathy (LVNC) is a rare myocardial disorder characterized by abnormal myocardial tissue formation in which the left ventricular wall appears to be trabecular with prominent intertrabecular recesses. The diagnosis of LVNC is predominantly reliant on cardiac imaging, namely thoracic echocardiography, however, cardiac MRI is indicated in conditions in which echocardiography is inconclusive. Diagnostic criteria for both echocardiography and cardiac MRI differ, however, the general principle of diagnosis is a comparison of the thickness of non-compacted to compacted myocardial tissue.

A Classic Pattern of Type 1 Brugada Syndrome on ECG: A Case Report.

Brugada syndrome is an inherited disorder characterized by a channelopathy of cardiac sodium, potassium, and calcium channel. The pathophysiology of this disorder is not completely elucidated yet, however, most of the reported cases are caused by a pathogenic alteration in the SCN5A gene, leading to the malfunction of cardiac sodium channels. Several stressors are well known to unmask this pathology including fever and electrolytes imbalance.

A Classic Pattern of Wellens Syndrome on ECG: A Case Report.

Wellens syndrome is usually diagnosed in asymptomatic patients with normal or only slightly elevated cardiac enzymes. There are two different ECG patterns (Type A and Type B) described in the literature. Earlier studies demonstrated that the appearance of the Wellens pattern had a specificity of 89% and a positive predictive value of 86% for severe stenosis of the left anterior descending artery (LAD) hence a timely recognition and therapeutic approach may prevent fatal outcomes in the patients.

Mirizzi Syndrome: An Unusual Complication of Cholelithiasis.

Mirizzi syndrome is a rare condition caused by the obstruction of the common bile duct or common hepatic duct by external compression from multiple impacted gallstones or a single large impacted gallstone in Hartman's pouch. The condition can easily be confused with choledocholithiasis, bile duct stricture or cholangiocarcinoma due to the presence of obstructive jaundice hence may be overlooked due to the rarity of the condition. The incidence of Mirizzi syndrome among patients with gallstones is reported to range from 0.

"Moving the Science Forward": Faculty Perceptions of Culturally Diverse Mentor Training Benefits, Challenges, and Support.

There is a pressing need for deeper cultural awareness among postsecondary faculty, yet few studies focus on institutions with developing research infrastructure, which enroll large proportions of racially minoritized students. Using social exchange theory, we investigate faculty members' perceptions of "culturally diverse mentor training," which includes culturally aware mentor (CAM) training, , and self-designed mentor training initiatives. Data come from qualitative interviews with 74 faculty who participated in culturally diverse mentor training activities across 10 master's and doctoral institutions in the early stages of implementing grant-funded interventions focused on determining the most effective ways to engage and retain racially minoritized students in biomedical research.

[Food and Nutritional Surveillance System (SISVAN) in children from Rio Grande do Sul State, Brazil: coverage, nutritional status, and data reliability].

This study aimed to evaluate: the coverage of the Food and Nutritional Surveillance System (SISVAN) in the State of Rio Grande do Sul, Brazil, and it Regional Health Offices in 2006; the nutritional status of children 0-10 years of age; and the reliability of data on nutritional status recorded in the system. A cross-sectional descriptive study was conducted with secondary data on 63,320 children. Coverage was defined as the proportion of children younger than 10 years covered by the Family Health Strategy in the State's various municipalities (counties).

The seeds from Plantago ovata lower plasma lipids by altering hepatic and bile acid metabolism in guinea pigs.

Psyllium, the husks from Plantago ovata (PO), is recognized as a potent agent in lowering plasma cholesterol. In this study, we tested the potential hypolipidemic effects of the seeds from PO and the mechanisms associated with the lowering of plasma lipids. Male Hartley guinea pigs (n = 30; 10 per group) were fed either a control diet or diets containing 7.
