Seagliders are small, reusable autonomous underwater vehicles designed to glide from the ocean surface to a programmed depth and back while measuring temperature, salinity, depth-averaged current, and other quantities along a sawtooth trajectory through the water. Their low hydrodynamic drag and wide pitch control range allows glide slopes in the range 0.2(More)
OBJECT Even with improved prenatal and neonatal care, intraventricular hemorrhage (IVH) occurs in approximately 25%-30% of preterm infants, with a subset of these patients developing hydrocephalus. This study was undertaken to describe current trends in hospitalization of preterm infants with posthemorrhagic hydrocephalus (PHH) using the Nationwide(More)
BACKGROUND AND PURPOSE Because of recent advances in minimally invasive surgical techniques, robot-assisted radical prostatectomy (RARP) has become the primary treatment option in prostate cancer. RARP, however, necessitates patients to be placed in a steep Trendelenberg position, which presents multiple opportunities for complications relating to the(More)
The mouse incisor is a valuable but under-utilized model organ for studying the behavior of adult stem cells. This remarkable tooth grows continuously throughout the animal's lifetime and houses two distinct epithelial stem cell niches called the labial and lingual cervical loop (laCL and liCL, respectively). These stem cells produce progeny that undergo a(More)
CONTEXT In 2000, the Centers for Disease Control and Prevention began funding health departments to implement integrated electronic systems for disease surveillance. OBJECTIVE Determine the impact of discontinuing provider reporting for chronic hepatitis B and C, hepatitis A, and select enteric diseases. DESIGN Laboratory and provider surveillance(More)
BACKGROUND Patients with cerebrovascular disease undergo complex surgical procedures, often requiring prolonged inpatient hospitalization. Previous studies have demonstrated associations between racial/demographic factors and clinical outcomes in patients undergoing cerebrovascular procedures (CVPs). The Centers for Medicare and Medicaid Services have(More)
OBJECTIVE Previous studies have suggested disparities in quality of health care and time to treatment across socioeconomic groups. Such differences can be of greatest consequence in the setting of emergent medical conditions. Surgical or endovascular treatment of ruptured cerebral aneurysms within the first 3 days of aneurysmal subarachnoid hemorrhage(More)
OBJECT As health care administrators focus on patient safety and cost-effectiveness, methodical assessment of quality outcome measures is critical. In 2008 the Centers for Medicare and Medicaid Services (CMS) published a series of "never events" that included 11 hospital-acquired conditions (HACs) for which related costs of treatment are not reimbursed.(More)
The optimal time to closure of a newborn with an open neural tube defect (NTD–myelomeningocele) has been the subject of a number of investigations. One aspect of timing that has received attention is its relationship to repair site and central nervous system (CNS) infection that can lead to irreversible deficits and prolonged hospital stays. No studies have(More)
OBJECTIVE To evaluate the association between weekend admission to hospital and 11 hospital acquired conditions recently considered by the Centers for Medicare and Medicaid as "never events" for which resulting healthcare costs are not reimbursed. DESIGN National analysis. SETTING US Nationwide Inpatient Sample discharge database. PARTICIPANTS 351(More)
