Sickle cell disease (SCD) refers to a group of inherited blood disorders with considerable morbidity that causes severe pain, reduces life expectancy, and requires significant self-management. Acute painful episodes are the hallmark SCD, but persistent daily pain is also highly prevalent in this population. Characterising impact experience SCD-related (i.e., sleep disruption, frequent emergency...

BACKGROUND Sudden cardiac death (SCD) is a major clinical and public health problem. METHODS AND RESULTS United States (US) vital statistics mortality data from 1989 to 1998 were analyzed. SCD is defined as deaths occurring out of the hospital or in the emergency room or as "dead on arrival" with an underlying cause of death reported as a cardiac disease (ICD-9 code 390 to 398, 402, or 404 to...

BACKGROUND Most sudden cardiac death (SCD) events occur in the general population among persons who do not have any prior history of clinical heart disease. We sought to develop a predictive model of SCD among US adults. METHODS We evaluated a series of demographic, clinical, laboratory, electrocardiographic, and echocardiographic measures in participants in the ARIC study (Atherosclerosis Ri...

Human immunodeficiency virus (HIV) and sickle cell disease (SCD) are regarded as endemic in overlapping geographic areas; however, for most countries only scarce data on the interaction between HIV and SCD and disease burden exist. HIV prevalence in SCD patients varies between 0% and 11.5% in published studies. SCD has been suggested to reduce disease progression of HIV into AIDS. Various inter...

A hallmark of targeted cancer therapies is selective toxicity among cancer cell lines. We evaluated results from a viability screen of over 200,000 small molecules to identify two chemical series, oxalamides and benzothiazoles, that were selectively toxic at low nanomolar concentrations to the same 4 of 12 human lung cancer cell lines. Sensitive cell lines expressed cytochrome P450 (CYP) 4F11, ...

background: sickle-cell disease (scd) is an inherited hemoglobin childhood disorder, frequently complicated by pulmonary hypertension and cardiac involvement. cardiovascular events and complications are the leading cause of mortality and morbidity in patients with scd. tissue doppler imaging and the myocardial performance index (tei index), are simple indices for the assessment of the cardiac f...

Among adults with sickle cell disease (SCD), pulmonary complications are a leading cause of death. Yet, the natural history of lung function in adults with SCD is not well established. We conducted a retrospective cohort study of adults with SCD who had repeated pulmonary function tests performed over 20 years of age. Ninety-two adults were included in this cohort. Rate of decline in FEV(1) for...

BACKGROUND Sympathetic activation influences the risk of ventricular arrhythmias and sudden cardiac death (SCD), mediated in part by the beta2-adrenergic receptor (B2AR). We investigated whether variation in the B2AR gene is associated with SCD risk. METHODS AND RESULTS In this study, 4441 white and 808 black Cardiovascular Health Study (CHS) participants were followed up prospectively for SC...

This literature review is devoted to the problem of studying sudden cardiac death (SCD) in hypertrophic cardiomyopathy (HCM). It covers prevalence of SCD and its structure among young individuals and trained athletes, contains discussion of relation of SCD to sex, age, and hypertrophic response of myocardium to physical exercise. Modern views on arrhythmogenic substrate underlying SCD in HCM as...

A reliable risk factor for sudden cardiac death (SCD) for the general population remains to be defined. We propose the omega-3 index, defined as the combined percentage of eicosapentaenoic (EPA) and docosahexaenoic acids (DHA) in red blood cell membranes. It reflects the EPA + DHA status of a given individual. It can be determined by a standardised and reproducible laboratory procedure. Several...
