Risk Factors for Failure of OPAT （Outpatient Parenteral Antimicrobial Therapy） in Veterans with Staphylococcus aureus Bacteremia

引用

j.urnal of Pharmacy and Pharmacology 2016年第6期4卷 241-247页

作者： john j. veillette Leslie Bittner Marion j. Skalweit Usha Stiefel Christopher j. Burant Amy A.Hirsch Sharanie Sims Pharmacy Service Louis Stokes Cleveland Department of Veterans Affairs Medical Center (LSCDVAMC) Cleveland OH USA Medicine Service LSCDV.4MC Cleveland OH USA Case Western Reserve University School of Medicine Cleveland OH USA Cleveland Geriatric Research Education and Clinical Center (GRECC) LSCDVAMC Cleveland OH USA Case Western Reserve University Frances Payne Bolton School of Nursing Cleveland OH USA

To identify risk factors for failure of OPAT （outpatient parenteral antimicrobial therapy） among veterans with SAB （Staphylococcus aureus bacteremia）, a retrospective review was conducted of all patients receiving OPAT for SAB between 01/2011-09/2013 at a large, tertiary-care VA （Veterans＇ Affairs） medical center. Treatment failure was defined as incomplete therapy, therapy extension, infection relapse, or hospital admission or surgical intervention within 60 days of therapy completion. Of 118 SAB patients treated with OPAT, 101 met inclusion criteria. Treatment failure occurred in 36 （35.6%） patients. In multivariate analysis, heart failure （OR 3.67; CI 1.13-12.0）, previous OPAT （OR 14.1; CI 2.02-97.8）, immunosuppression （OR 10.5; CI 1.74-63.3）, and treatment with daptomycin （OR 9.56; CI 1.89-48.4） were independently associated with failure. A trend toward lower failure rates was seen in the community living center, a VA long-term care facility possessing its own infectious diseases consultation service. In veterans with SAB, specific health factors were associated with higher rates of OPAT failure. Given the morbidity and cost of SAB treatment failures, similar analyses may benefit other large OPAT programs to optimize the selection of patients and settings in which successful treatment will most likely occur.

A Modified Lagrange Method for Solving Convex Quadratic Optimization Problems

引用

Open j.urnal of Optimization 2024年第1期13卷 1-20页

作者： Twum B. Stephen Avoka john Christian j. Etwire School of Mathematical Science C. K. Tedam University of Technology and Applied Sciences Navrongo Ghana Department of Mathematics University for Development Studies Tamale Ghana

In this paper, a modified version of the Classical Lagrange Multiplier method is developed for convex quadratic optimization problems. The method, which is evolved from the first order derivative test for optimality of the Lagrangian function with respect to the primary variables of the problem, decomposes the solution process into two independent ones, in which the primary variables are solved for independently, and then the secondary variables, which are the Lagrange multipliers, are solved for, afterward. This is an innovation that leads to solving independently two simpler systems of equations involving the primary variables only, on one hand, and the secondary ones on the other. Solutions obtained for small sized problems (as preliminary test of the method) demonstrate that the new method is generally effective in producing the required solutions.

Evaluation of a Wireless Solar Powered Personal Weather Station

Agricultural Sciences 2024年第1期15卷 36-53页

作者： Robert j. Lascano Timothy S. Goebel Dennis C. Gitz III john E. Stout Cropping Systems Research Laboratory Wind Erosion and Water Conservation Research Unit USDA-ARS Lubbock TX USA

We are evaluating dryland cotton production in Martin County, Texas, measuring cotton lint yield per unit of rainfall. Our goal is to collect rainfall data per 250 - 400 ha. Upon selection of a rainfall gauge, we realized that the cost of using, for example, a tipping bucket-type rain gauge would be too expensive and thus searched for an alternative method. We selected an all-in-one commercially available weather station;hereafter, referred to as a Personal Weather Station (PWS) that is both wireless and solar powered. Our obj.ctive was to evaluate average measurements of rainfall obtained with the PWS and to compare these to measurements obtained with an automatic weather station (AWS). For this purpose, we installed four PWS deployed within 20 m of the Plant Stress and Water Conservation Meteorological Tower that was used as our AWS, located at USDA-ARS Cropping Systems Research Laboratory, Lubbock, TX. In addition, we measured and compared hourly average values of short-wave irradiance (Rg), air temperature (Tair) and relative humidity (RH), and wind speed (WS), and calculated values of dewpoint temperature (Tdew). This comparison was done over a 242-day period (1 October 2022-31 May 2023) and results indicated that there was no statistical difference in measurements of rainfall between the PWS and AWS. Hourly average values of Rg measured with the PWS and AWS agreed on clear days, but PWS measurements were higher on cloudy days. There was no statistical difference between PWS and AWS hourly average measurements of Tair, RH, and calculated Tdew. Hourly average measurements of Rg and WS were more variable. We concluded that the PWS we selected will provide adequate values of rainfall and other weather variables to meet our goal of evaluating dryland cotton lint yield per unit rainfall.
