Modifiable Factors to Decrease the Cost of Robotic-Assisted Procedures

In 2000, the US Food and Drug Administration approved the da Vinci Surgical System® for use in the United States. Since that time, the number of surgical robotic systems throughout the United States has continued to grow. The costs for using the system include the initial purchase ($1 million to $2.3 million) plus annual maintenance fees ($100,000 to $150,000) and the cost of limited-use or disposable instruments. Increasing the number of procedures that are performed using the robotic system can decrease the per-procedure costs. Two modifiable factors that contribute to increasing the annual caseload are increasing the number of surgeons capable of using the system and having a properly educated perioperative nursing team. An educated surgical team decreases turnover time, facilitates proper flow of each surgical procedure, and is able to actively and passively solve intraoperative problems.     

Perioperative Nursing and Education: What the IOM Future of Nursing Report Tells Us

Changes in the current health care system have rendered the system unprepared to support new demands. Similarly, nursing education both before and after licensure is no longer adequate. Four of the eight recommendations in the Institute of Medicine’s Future of Nursing report involve changes to nursing education and pose significant goals to achieve. This makes creating innovative ways to meet the demand for educating RNs a necessity. This article discusses the Institute of Medicine’s recommendations, how they relate to perioperative nursing, and ways in which nurses and educators can help promote expectations.     

Antioxidant and anti-atherogenic activities of three Piper species on atherogenic diet fed hamsters

Atherogenic diet is known to induce high plasma lipid concentration, oxidative stress and early atherosclerosis. Antioxidants have potentials to counter the effect of atherogenic diet.The present research aims at evaluating the antioxidant and anti-atherosclerotic activities of three Piper species (Piper guineense, Piper nigrum and Piper umbellatum) on atherogenic diet fed hamsters.Hamsters divided into 8 groups: normal control, atherosclerotic control and six test groups. The normal animals fed normal rodent chow, the atherosclerotic control animals fed the same rodent chow supplemented with 0.2% cholesterol and 10% coconut oil (high cholesterol diet). The 6 test groups’ animals fed same diet as the atherosclerotic control group but with additional supplementation of 2 graded doses (1 and 0.25 mg/kg body weight, o.p.) of plant extracts for 12 weeks.The atherogenic diet induced a collapse of the erythrocyte antioxidant defense system (significant decrease in superoxide dismutase, catalase and glutathione peroxidase activities). Atherogenic diet also induced an increase in plasma total cholesterol, triglyceride, thiobarbituric acid reactive substances (TBARS), oxidation of low density lipoprotein cholesterol (LDL) and accumulation of foam cells in the aorta a hall mark for atherosclerosis. Administration of the Piper species prevented the collapse of the antioxidant system and the increase of plasma parameters maintaining them towards normality. The Piper species also prevented LDL oxidation by increasing the time (lag time) for its oxidation.The results suggest that these Piper species have significant antioxidant and anti-atherogenic effect against atherogenic diet intoxication.
