Laboratory abnormalities at the start of treatment of end-stage renal disease (ESRD) have been reported as worse in racial/ethnic minorities than in white patients, suggesting racial disparities in care. It is not known whether these differences are attributable to racial/ethnic differences in socioeconomic status (SES). ⋯ Minorities, particularly black patients, had more severe laboratory abnormalities at the start of ESRD treatment than white patients. These differences were not readily attributable to SES differences. Absence of medical insurance, SES, and race/ethnicity were associated with the likelihood of predialysis use of epoietin.

Venous thromboembolism (VTE) manifesting as deep vein thrombosis (DVT) and pulmonary embolism (PE) remains a common vascular disease with high mortality and morbidity. Our aim was to study the clinical spectrum of VTE, assess its incidence in the general population, and evaluate potential risk factors. ⋯ Overweight, varicose veins, cancer, inflammatory bowel disease, fractures, surgery, and use of oral corticosteroids, oral contraceptives, and opposed hormone therapy were independent risk factors for both DVT and PE. The magnitude of the association with some risk factors varied between DVT and PE, as well as between fatal and nonfatal PE.

Previous studies have suggested that minor changes in thyroid function are associated with risk of atrial fibrillation (AF). Our objective was to determine the relationship between thyroid function and presence of atrial fibrillation (AF) in older subjects. ⋯ The biochemical finding of subclinical hyperthyroidism is associated with AF on resting electrocardiogram. Even in euthyroid subjects with normal serum TSH levels, serum free T(4) concentration is independently associated with AF.
