Vitamin K is required for the activity of various biologically active proteins in our body. Apart from clotting factors, vitamin K-dependent proteins include regulatory proteins like protein C, protein S, protein Z, osteocalcin, growth arrest-specific gene 6 protein, and matrix Gla protein. Glutamic acid residues in matrix Gla protein are γ-carboxylated by(More)
Excessive dynamic airway collapse (EDAC) refers to abnormal and exaggerated bulging of the posterior wall within the airway lumen during exhalation. This condition is pathological if the reduced airway lumen is <50% of the normal. It is a relatively new disease entity that is recognised more easily now with the increased use of multi-detector row CT. EDAC(More)
Azacitidine is a pyrimidine nucleoside analog licensed for treatment of adult patients with myelodysplastic syndrome. Azacitidine acts as an inducer of cell differentiation by causing demethylation and re-expression of genes silenced by hypermethylation. We report a 56-year-old man with myelodysplastic syndrome who developed interstitial lung disease after(More)
Heart failure is a growing health and economic problem in America, and outcomes continue to remain dismal, particularly for those presenting with acute heart failure syndrome (AHFS). In theory, arginine vasopressin antagonists (VRAs) could be useful in both acute and chronic heart failure, depending on which vasopressin receptor is targeted. Most studies of(More)
Atherosclerotic coronaryarterydisease (CAD)andperipheral arterial disease are global public health and socio-economic issues associated with important treatment advances that affect millions of lives every year. Hypertrophic cardiomyopathy (HCM), although less common, has also become a treatable form of heart disease with demonstrable reduction in mortality(More)
BACKGROUND Since pulmonary artery balloon flotation catheterization was first introduced in 1970, by HJ Swan and W Ganz, it has been widely disseminated as a diagnostic tool without rigorous evaluation of its clinical utility and effectiveness in critically ill patients. A pulmonary artery catheter (PAC) is inserted through a central venous access into the(More)
BACKGROUND Providers' understanding of the 2013 American College of Cardiology (ACC)/American Heart Association (AHA) cholesterol guideline in clinical practice is not known. METHODS We designed a questionnaire, which was administered to internal medicine, family practice, cardiology, and endocrinology providers at 21 venues across the United States. We(More)
Hypotension can be a manifestation of transfusion reactions, including acute hemolysis, bacterial contamination, transfusion-related acute lung injury, and anaphylaxis. In addition to hypotension, these reactions usually present with other characteristic symptoms and signs. In rare cases, hypotension is the only manifestation of a transfusion reaction. This(More)
Heart failure (HF) poses a significant economic burden on our health-care resources with very high readmission rates. Remote monitoring has a substantial potential to improve the management and outcome of patients with HF. Readmission for decompensated HF is often preceded by a stage of subclinical hemodynamic decompensation, where therapeutic interventions(More)
