Study design is critical to ensure that research questions are answered in an appropriate and rational manner for all aspects of health, but particularly in emergency care. Appropriate study design selection is one of the most critical decisions to…

Solid organ transplantation in children and adolescents provides many benefits through improving critical organ function, including better growth, development, cardiovascular status, and quality of life. Unfortunately, bone status may be adversely…

The morbidity and mortality of adult and pediatric chronic kidney disease (CKD) and end-stage renal disease (ESRD) populations are mainly driven by cardiovascular disease (CVD). Improving CVD outcomes focuses on risk assessment of factors including…

Clear and precise writing is a vital skill for healthcare providers and those involved in global emergency care research. It allows one to publish in scientific literature and present oral and written summaries of their work. However, writing skills…

The specialty of Emergency Medicine continues to expand and mature worldwide. As a relatively new specialty, the body of research that underpins patient management in the emergency department (ED) setting needs to be expanded for optimum patient…

The order Cetacea (dolphins, whales, and porpoises) evolved from terrestrial artiodactyls (even‐toed ungulates) around 50 million years ago. This transition from land to water occurred over an evolutionarily short period of less than 10 million years…

BACKGROUND: Computed tomography (CT) diagnostic accuracy for blunt bowel and mesenteric injuries (BBMI) is controversial. DATA SOURCES: A literature review to compute aggregate CT performance and individual CT sign sensitivity, specificity, and…

Objective: The Pandemic and All-Hazards Preparedness Act calls for establishing a competency-based training program to train public health practitioners. To inform such training, the Centers for Disease Control and Prevention and the Association of…

OBJECTIVE: To describe the impact of a national interventional collaborative on pediatric readiness within General Emergency Departments. STUDY DESIGN: A prospective, multicenter, interventional study measured pediatric readiness in general…

Background Obstructive sleep apnea (OSA) has been described as a risk factor for cardiac arrhythmias. Its association with atrial fibrillation has been established. However, relationships with other arrhythmias and conduction disorders have not been…

The purpose of this exploratory study is to: (1) assess prevalence of childhood adversities and posttraumatic stress disorder (PTSD); (2) assess their association, and; (3) explore whether proximal sources of stress affect this relationship and/or…

Cardiac fibrosis caused by adverse cardiac remodeling following myocardial infarction can eventually lead to heart failure. Although the role of soluble factors such as TGF-beta is well studied in cardiac fibrosis following myocardial injury, the…

A 24-year-old woman developed encephalopathy, branch retinal artery occlusion, hearing loss, and had "snowball" lesions in the corpus callosum, classic findings of Susac syndrome (SuS). Despite intensive immunosuppressive therapy, she lapsed into a…

Susac syndrome is a rare, immune-mediated disease characterized by encephalopathy, branch retinal artery occlusion, and hearing loss. Herein, we describe the electron microscopic findings of three brain biopsies and two brain autopsies performed on…

Accumulating evidence suggests that inflammation has a key role in the pathogenesis of osteoarthritis (OA). Nitric oxide (NO) has been established as one of the major inflammatory mediators in OA and drives many pathological changes during the…

Asthma is characterized by pathological airway remodeling resulting from persistent myofibroblast activation. Although transforming growth factor beta 1 (TGFβ1), mechanical signals, and reactive oxygen species (ROS) are implicated in fibroblast…

Cardiovascular disease is the leading cause of worldwide mortality. Intravital microscopy has provided unprecedented insight into leukocyte biology by enabling the visualization of dynamic responses within living organ systems at the cell-scale. The…

Background Bile acid‐CoA: amino acid N‐acyltransferase (BAAT) is the enzyme which is responsible for bile acid (BA) conjugation with glycine and taurine in the final step of bile acid synthesis in humans. More than 98% of BA conjugation occurs in the…

Mitochondrial function is impaired in osteoarthritis (OA) but its impact on cartilage catabolism is not fully understood. Here, we investigated the molecular mechanism of mitochondrial dysfunction-induced activation of catabolic response in …

OBJECTIVE: Lysosomes are the major catabolic organelle of the cell and regulate the macromolecular and organelle turnover and programmed cell death. Here, we investigated the lysosome dysfunction in cartilage and its role in chondrocytes apoptosis…

Objective: Cytokine expression is tightly regulated posttranscriptionally, but high levels of interleukin‐6 (IL‐6) in patients with osteoarthritis (OA) indicate that regulatory mechanisms are disrupted in this disorder. The enzyme ZCCHC6 (zinc‐finger…
