PURPOSE Continuous renal replacement therapy (CRRT) is becoming the treatment of choice for supporting critically ill pediatric patients. However, a few studies present have reported CRRT use and outcome in neonates weighing less than 3 kg. The aim of this study is to describe the clinical application, outcome, and complications of CRRT in small neonates. METHODS A retrospective review was pe...

BACKGROUND Few published studies address the survival of kidney transplantation patients after valve surgery, and none address relative outcomes related to tissue versus nontissue prosthesis. This study aimed to assess survival of US kidney transplantation patients after cardiac valve replacement and to compare associations of valve selection. METHODS AND RESULTS Of 1 698 706 patients in the ...

Background—Few published studies address the survival of kidney transplantation patients after valve surgery, and none address relative outcomes related to tissue versus nontissue prosthesis.

A generalized age-replacement policy with age-dependent minimal repair and random leadtime is considered. A model is developed for the average cost per unit time and is based on the stochastic behavior of the assumed system and reflects the cost of storing a spare as well as the cost of system downtime. Determination of the minimum-cost policy time is described and illustrated with a numerical ...

BACKGROUND Total joint replacements for end-stage osteoarthritis of the hip and knee are cost-effective and demonstrate significant clinical improvement. However, robust population based lifetime-risk data for implant revision are not available to aid patient decision making, which is a particular problem in young patient groups deciding on best-timing for surgery. METHODS We did implant surv...

background degenerative retinal diseases, including age related macular degeneration, glaucoma, and hereditary retinal dystrophies are major causes of blindness. the principal defect in these diseases is cell loss which is amenable to both cell based neuroprotective and neuroregenerative therapies. to briefly review the lines of research and potential candidates for cell based therapies among r...

The effects of estrogen replacement therapy on prognosis in women with established coronary disease remain uncertain. The authors conducted a retrospective cohort study of 726 women (mean age, 66.2 years) who survived first myocardial infarction to hospital discharge from 1980 through 1991, while enrolled at Group Health Cooperative of Puget Sound in western Washington State. Estrogen replaceme...

the cu, pb, zn, ag-au deposit of amensif is located on the northern flank of the western high atlas. this deposit is hosted in lower cambrian carbonate bars and is structurally controlled by ne-sw to e-w trending fault structures and is spatially associated with the permian 273 ma azegour granite. ore reserves are around 0.5 mt and grades are 3.21% zn, 0.58% pb, 0.86% cu with 83.31 ppm ag and 0...
