Historically, Medicare reimbursed health care facilities on the basis of costs. Cost based reimbursement methods have long been criticized because they are often complex, provide few incentives for furnishing care efficiently, and result in unpredictable payments. Because of the rapid rate of growth in outlays for inpatient hospital care, Congress first directed implementation of a prospective ...

In treating Major Depressive Disorder with associated painful physical symptoms (PPS), the effect of duloxetine on PPS has been shown to decompose into a direct effect on PPS and an indirect effect on PPS via depressive symptoms (DS) improvement. To evaluate the changes in relative contributions of the direct and indirect effects over time, we analyzed pooled data from 3 randomized double-blind...

The intracellular signaling pathways associated with neuronal injury after perforant pathway stimulation of the rodent hippocampus have not been examined. To determine whether activation of the p42/p44 (Erk1/2) MAP kinase (MAPK) phosphorylation cascade is linked to neuronal injury after perforant pathway stimulation (PPS), we stained for phosphorylated Erk1/2 (P-Erk1/2) and for DNA fragmentatio...

When the Health Care Financing Administration implemented the Medicare prospective payment system (PPS), several types of hospitals and hospital units were excluded from the new reimbursement system, and they remained under the reasonable cost reimbursement system, subject to the target rate of increase limits. The implementation of PPS has been accompanied by several changes in hospital classi...

Children's hospitals have been excluded from the Medicare prospective payment system (PPS) because of concerns over the applicability of the DRG case-mix system and PPS payment weights to pediatric hospitalization. Nevertheless, DRG-based payment systems are being adopted by State Medicaid agencies and private third-party payers, and the Health Care Financing Administration has been mandated to...

We study the comparability of the two most important measurement methods used for the characterization of semiconductor saturable absorber mirrors (SESAMs). For both methods, single-pulse spectroscopy (SPS) and pump-probe spectroscopy (PPS), we analyze in detail the time-dependent saturation dynamics inside a SESAM. Based on this analysis, we find that fluence-dependent PPS at complete spatial ...

Pine polyphenols (PPs) are bioactive dietary constituents that enhance health and help prevent diseases through antioxidants. Antioxidants reduce the level of oxidative damages caused by ionizing radiation (IR). The main purpose of this paper is to study the protective effect of PPs on peripheral blood, liver and spleen injuries in mice induced by IR. ICR (Institute of Cancer Research) male mic...
