Abstract Animations for the Communication and Assessment of Pain in Adults: Cross-Sectional Feasibility Study.

Background: Pain is the most common physical symptom requiring medical care, yet the current methods for assessing pain are sorely inadequate. Pain assessment tools can be either too simplistic or take too long to complete to be useful for point-of-care diagnosis and treatment.

Objective: The aim was to develop and test Painimation, a novel tool that uses graphic visualizations and animations instead of words or numeric scales to assess pain quality, intensity, and course.

Phase 1 Study of a Sulforaphane-Containing Broccoli Sprout Homogenate for Sickle Cell Disease.

Sickle cell disease (SCD) is the most common inherited hemoglobinopathy worldwide. Our previous results indicate that the reduced oxidative stress capacity of sickle erythrocytes may be caused by decreased expression of NRF2 (Nuclear factor (erythroid-derived 2)-like 2), an oxidative stress regulator. We found that activation of NRF2 with sulforaphane (SFN) in erythroid progenitors significantly increased the expression of NRF2 targets HMOX1, NQO1, and HBG1 (subunit of fetal hemoglobin) in a dose-dependent manner.

Factors associated with survival in a contemporary adult sickle cell disease cohort.

In this study, the relationship of clinical differences among patients with sickle cell disease (SCD) was examined to understand the major contributors to early mortality in a contemporary cohort. Survival data were obtained for 542 adult subjects who were enrolled since 2002 at three university hospitals in the southeast United States. Subjects were followed up for a median of 9.

Effect of propranolol as antiadhesive therapy in sickle cell disease.

Sickle red blood cells (SSRBCs) adhere to both endothelial cells (ECs) and the extracellular matrix. Epinephrine elevates cyclic adenosine monophosphate in SSRBCs and increases adhesion of SSRBCs to ECs in a β-adrenergic receptor and protein kinase A-dependent manner. Studies in vitro as well as in vivo have suggested that adrenergic stimuli like epinephrine may contribute to vaso-occlusion associated with physiologic stress.

MYH9 and APOL1 are both associated with sickle cell disease nephropathy.

Renal failure occurs in 5-18% of sickle cell disease (SCD) patients and is associated with early mortality. At-risk SCD patients cannot be identified prior to the appearance of proteinuria and the pathobiology is not well understood. The myosin, heavy chain 9, non-muscle (MYH9) and apolipoprotein L1 (APOL1) genes have been associated with risk for focal segmental glomerulosclerosis and end-stage renal disease in African Americans.

Living with sickle cell disease: traversing 'race' and identity.

Objectives: Sickle cell disease (SCD) has a distinctive social history that continues to influence research and clinical practice related to the disease. Despite the historical link between SCD and concepts of 'race', there is limited empirical information on the relationships among SCD patients' 'race'/ancestry/ethnicity/nationality, their beliefs and attitudes associated with these identities, and their SCD experiences and outcomes. We conducted a preliminary study to explore some of these relationships.

Clinical and sociodemographic factors predict coping styles among adults with sickle cell disease.

Unlabelled: Sickle cell disease (SCD) presents a significant physical and psychological burden for persons with this chronic disease; however, little is known about how individuals with SCD--adult patients in particular--cope with disease-related stressors. The aim of this study was to identify and characterize factors that may influence the styles of coping among adults with SCD.

Methods: The study sample included 46 adult patients with SCD-20 men and 26 women--with an average age of 32.

Cardiopulmonary complications leading to premature deaths in adult patients with sickle cell disease.

Sickle cell disease (SCD) is associated with early mortality. We sought to determine the incidence, cause, and risk factors for death in an adult population of patients with SCD. All patients aged >/=18 years seen at the Adult Sickle Cell Center at Duke University Medical Center between January 2000 and April 2005 were enrolled.

Pulmonary hypertension associated with sickle cell disease: clinical and laboratory endpoints and disease outcomes.

Screening for pulmonary hypertension (pHTN) has not yet become routine in sickle cell disease (SCD), despite clinical evidence of its high prevalence and associated mortality. Our objectives are to identify clinical conditions and laboratory findings predictive of/or associated with pHTN. One hundred twenty-five adult outpatients with Hb SS, SC, SOArab, Sbeta(0), or Sbeta(+) thalassemia, who underwent echocardiography and/or right heart catheterization due to cardiorespiratory symptoms, were studied.

Moderate chronic pain, weight and dietary intake in African-American adult patients with sickle cell disease.

In this exploratory study, we evaluated weight status and dietary intake patterns during painful episodes in adult patients with SCD. Specifically, we explored the relation between pain severity and body mass index (BMI), and we tested the hypothesis that dietary intake would be reduced and dietary content altered during periods of increased pain. We conducted an analysis of survey data from 62 patients involved in a longitudinal evaluation of the relationship of medical and psychosocial factors to pain.
