In this report, we investigate approaches and algorithms for establishing a multicast session in a mesh network while protecting the session against any single link failure, e.g., a fiber cut in an optical network. We propose two new and efficient approaches for protecting a multicast session: 1) segment protection in which we protect each segment in the primary tree separately (rather than the...

BACKGROUND Adult Helicobacter pylori-positive patients by 13C-urea breath test with uninvestigated dyspepsia symptoms were randomized to 1-week eradication treatment with omeprazole, metronidazole and clarithromycin (OMC) vs. omeprazole and placebo antimicrobials (OPP) in the Canadian Adult Dyspepsia Empiric Treatment-H. pylori-positive (CADET-Hp) study. AIM To perform an economic evaluation ...

PURPOSE Little is known about potential effects of smoking on ocular blood flow regulation. In the present study, the hypothesis was that choroidal blood flow (CBF) changes during an increase in ocular perfusion pressure induced by isometric exercise are altered in chronic smokers. METHODS The study was performed in 24 (12 smokers and 12 nonsmokers) healthy male volunteers in an observer-mask...

Purpose To investigate changes in eye coats, axial length, and ocular perfusion pressure (OPP) in hemodialysis (HD) patients with chronic renal failure (CRF). Methods We included HD patients who were diagnosed with CRF in our hospital from January to December 2015. Fifty-two patients met the inclusion criteria; all right eyes were used for observation. Systolic and diastolic blood pressures w...

RESEARCH OBJECTIVE Hospital-acquired conditions, or HACs, often result in additional Medicare payments, generated during the initial hospitalization and in subsequent health care encounters. The purpose of this article is to estimate the incremental cost to Medicare, as measured by Medicare program payments, of six HACs. STUDY DESIGN The researchers used a matched case-control design to deter...
