Comparisons of clinical outcomes in hemodialysis (HD) and peritoneal dialysis (PD) patients have been marked by inconsistent results depending on the population studied and the methods used. In order to address this limitation of previous U.S. studies and to more specifically evaluate the higher-risk elderly population, we undertook a study of Medicare(More)
This study examined the effects of reinforcement contingencies designed to increase the performance of existing reading skills as well as the effects of instruction--modeling and practice--designed to increase skill level for oral reading fluency across three levels of reading materials. Results showed that a combination of contingencies, modeling, and(More)
Although numerous studies indicate that women have a higher early mortality from acute myocardial infarction (AMI) than men, reasons for the difference are largely unexplained. We studied the role of sex in the prognosis of 1,600 patients with AMI aged 30 to 74 years in the population-based Minnesota Heart Survey. A 50% random sample was taken of all AMI(More)
A male newborn underwent a myelomeningocele repair, with subsequent placement of a ventriculoperitoneal shunt for treatment of hydrocephalus. Five days after shunt surgery, the infant acutely developed a deeply sunken fontanel, pallor, tachypnea, bradycardia, and irritability. Chest radiographs revealed intrathoracic migration of the distal shunt tubing and(More)
PURPOSE When medications are modified in response to changing clinical conditions, confounding by indication arises that cannot be controlled using traditional adjustment. Inverse probability of treatment weights (IPTWs) can address this confounding given assumptions of no unmeasured confounders and that all patients have a positive probability of receiving(More)
