Air pollution exposure and head and neck cancer incidence.

To investigate air pollution's effect in the form of PM (particulate matter measuring less than 2.5 microns) on head and neck aerodigestive cancer incidence, an epidemiological cohort analysis was performed using data from the Surveillance Epidemiology and End Results national cancer database from the years 2002-2012. The relationship between US county mean PM levels and head and neck cancer (HNC) incidence rates were examined using a linear mixed model.

Most Patients Undergoing Ground And Air Ambulance Transportation Receive Sizable Out-Of-Network Bills.

"Surprise" out-of-network bills have come under close scrutiny, and while ambulance transportation is known to be a large component of the problem, its impact is poorly understood. We measured the prevalence and financial impact of out-of-network billing in ground and air ambulance transportation. For members of a large national insurance plan in 2013-17, 71 percent of all ambulance rides involved potential surprise bills.

Impact Of Medicare Readmissions Penalties On Targeted Surgical Conditions.

The Hospital Readmissions Reduction Program, announced in 2010 to penalize excess readmissions for patients with selected medical diagnoses, was expanded in 2013 to include targeted surgical diagnoses, beginning with hip and knee replacements. Whether these surgical penalties reduced procedure-specific readmissions is not well understood. Using Medicare claims, we evaluated the penalty announcements' effects on risk-adjusted readmission rates, episode payments, lengths-of-stay, and observation status use.

Transcatheter Mustard Revision Using Endovascular Graft Prostheses.

We describe the use of percutaneously inserted, transcatheter endovascular graft prostheses to exclude large Mustard baffle leaks in a high-surgical-risk patient. We used 3-dimensional-printed models to determine feasibility and to plan the procedure. Telescoping thoracic and abdominal graft extensions were placed in the inferior and superior limbs of the systemic venous pathways.

Better Patient Care At High-Quality Hospitals May Save Medicare Money And Bolster Episode-Based Payment Models.

US policy makers are making efforts to simultaneously improve the quality of and reduce spending on health care through alternative payment models such as bundled payment. Bundled payment models are predicated on the theory that aligning financial incentives for all providers across an episode of care will lower health care spending while improving quality. Whether this is true remains unknown.

Hospital board and management practices are strongly related to hospital performance on clinical quality metrics.

National policies to improve health care quality have largely focused on clinical provider outcomes and, more recently, payment reform. Yet the association between hospital leadership and quality, although crucial to driving quality improvement, has not been explored in depth. We collected data from surveys of nationally representative groups of hospitals in the United States and England to examine the relationships among hospital boards, management practices of front-line managers, and the quality of care delivered.

Medicare's Bundled Payment initiative: most hospitals are focused on a few high-volume conditions.

The Bundled Payments for Care Improvement initiative is a federally funded innovation model mandated by the Affordable Care Act. It is designed to help transition Medicare away from fee-for-service payments and toward bundling a single payment for an episode of acute care in a hospital and related postacute care in an appropriate setting. While results from the initiative will not be available for several years, current data can help provide critical early insights.

A Mac-1 antibody reduces liver and lung injury but not neutrophil sequestration after intestinal ischemia-reperfusion.

Background: Intestinal ischemia and reperfusion (I/R) result in leukosequestration and injury to the liver and lungs. The adherence-dependent oxidative burst of neutrophils requires cell adhesion through the Mac-1 integrin. Neutrophil-mediated tissue injury may depend on this specific cell adhesion event.
