Pure red cell aplasia (PRCA) and autoimmune hemolytic anemia (AIHA) have rarely been reported as an extrahepatic manifestation of acute hepatitis A (AHA). We report herein a case of AHA complicated by both PRCA and AIHA. A 49-year-old female with a diagnosis of AHA presented with severe anemia (hemoglobin level, 6.9 g/dL) during her clinical course. A diagnostic workup revealed AIHA and PRCA as...

BACKGROUND Dietary assessment tools are often too long, difficult to quantify, expensive to process, and largely used for research purposes. A rapid and accurate assessment of dietary fat intake is critically important in clinical decision-making regarding dietary advice for coronary risk reduction. We assessed the validity of the MEDFICTS (MF) questionnaire, a brief instrument developed to ass...

OBJECTIVE To determine the ability of the new American College of Cardiology and American Heart Association (ACC/AHA) 10-year atherosclerotic cardiovascular disease (ASCVD) risk algorithm in detecting high cardiovascular (CV) risk, RA patients identified by carotid ultrasonography (US) were compared with Systematic Coronary Risk Evaluation (SCORE) and QRisk II algorithms. METHODS SCORE, QRisk...

BACKGROUND Cardiovascular disease (CVD) and osteoporosis are 2 major public health problems that share common pathophysiological mechanisms. It is possible that strategies to reduce CVD risk may also benefit bone health. OBJECTIVE We tested the hypothesis that adherence to the 2006 American Heart Association Diet and Lifestyle Recommendations (AHA-DLR) is associated with bone health. DESIGN...

Acquired hemophilia A (AHA) is a rare bleeding disorder, caused by the development of autoantibodies (inhibitor) against endogenous clotting factor VIII (FVIII). common clinical manifestation subcutaneous bleeding, but soft tissue hematomas and excessive post-operative hemorrhages may also occur. diagnosis AHA made in patients presenting with an isolated prolonged activated partial thromboplast...

The American Heart Association (AHA) is known and respected worldwide as an organization that is a credible forum and source of scientific information for the prevention and treatment of patients with cardiovascular disease and stroke. Although the focus of the AHA has historically been within the United States, over the past few years, the group has felt a growing concern about the global burd...

Creating and maintaining adaptive educational applications is a hard work for teachers and developers. In order to help the author to perform these tasks the e-learning systems must provide authoring and management tools. In this chapter we are going to describe several useful tools for working with adaptive educational hypermedia systems, concretely with the AHA! system. AHA! is an well-known ...

A sudden comprehension that solves a problem, reinterprets a situation, explains a joke, or resolves an ambiguous percept is called an insight (i.e., the "Aha! moment"). Psychologists have studied insight using behavioral methods for nearly a century. Recently, the tools of cognitive neuroscience have been applied to this phenomenon. A series of studies have used electroencephalography (EEG) an...

The American Heart Association (AHA) continues its half-century tradition as the premier provider of the highest impact cardiovascular and stroke science information with this month’s debut of AHA Journals Online. The introduction of the AHA’s new World Wide Web (WWW) site is another major step toward expanding the reach of the journals, providing readers with virtually instant access to an unp...

The photoreactions of 9-[6-(4-azidobenzamido)hexylamino]acridine (AHA) and 9-[6-(2-diazocyclopentadienylcarbonyloxy)hexylamino]acridine (DHA) with double stranded DNA result in formation of single strand nicks and alkali labile sites (adducts) with an efficiency of 6 x 10(-3) nicks per AHA and 3 x 10(-2) nicks per DHA molecule. The alkali dependent DNA cleavage by AHA shows a pronounced A+G pre...
