Prevalence of erythromelalgia in the United States: a cross-sectional study using the All of Us database.

Erythromelalgia is a rare condition with no published estimates of prevalence from a diverse, nationwide cohort of American patients. We performed a cross-sectional analysis of the All of Us database to estimate the prevalence of erythromelalgia overall and by age groups. Of 410,361 participants, 47 were diagnosed with erythromelalgia, representing an overall age-adjusted prevalence of 10.3 (95% CI 7.4-13.3) per 100,000 people. The prevalence was higher in the 65 + age group (16, 95% CI 9.5-23, per 100,000 people) than the less than 65 age group (9.1, 95% CI 5.5-13, per 100,000 people). Further studies are needed to determine the burden of erythromelalgia in specific subgroups, such as race, within the United States.

Perceptions of exercise behavior and well-being in anomalous aortic origin of coronary arteries.

Anomalous aortic origin of a coronary artery (AAOCA) is associated with sudden death in the young. Risk stratification and management decision-making remain challenging. Data addressing post-diagnosis perceptions of exercise behavior and safety are lacking. We aimed to determine how AAOCA affects exercise behaviors, safety perceptions, and emotional well-being of patients/parents. Qualitative and quantitative analysis of AAOCA patient-/parent-specific survey was conducted to examine exercise frequency/restrictions, perceived safety of competitive/recreational exercise, and psychosocial well-being. Subgroups stratified by AAOCA subtype, surgical intervention, and physician-driven restrictions were compared using chi-squared and Fisher's exact tests. Cohen's kappa determined agreement in parent/child responses. AAOCA subtypes included 13 (24%) left AAOCA, 36 (67%) right AAOCA, and 5 (9%) other/unknown. Of 54 parents and 41 paired child responses, 22% of patients were physician-restricted from exercise. Parents imposed restrictions on competitive/recreational exercise 34%/26% of the time, respectively. Children without physician restrictions still self-restricted exercise 35% of the time. Parents reported feeling their child was unsafe exercising 61% competitively and 33% recreationally. Twenty-two percent of children reported feeling unsafe exercising, with good agreement to parental perceptions of competitive exercise safety (kappa = 0.779, p < 0.001). One-third of parents and children reported feeling sad, angry, or lonely, and about half reported feeling different. Importantly, 47% of children desired to exercise more. No difference was seen across restriction status, AAOCA subtype, or surgical management strategy. CONCLUSION: There are different perceptions of exercise behavior and safety following AAOCA evaluation, regardless of risk category or management strategy, impacting their well-being. These unmet needs should be at the forefront of care. WHAT IS KNOWN: • AAOCA is one of the leading causes of sudden cardiac death in the young. • Exercise restriction varies according to AAOCA subtype and its perceived risk of inducing myocardial ischemia. WHAT IS NEW: • There are different perceptions of exercise behavior and safety in patients and parents following a diagnosis of AAOCA, impacting their well-being. • Risk category or management strategy has no effect in patients' and parents' perception of exercise safety. • These unmet needs in this population should be at the forefront of care.
