background: surgical site infection is known as a common complication after cardiac surgery, and cefazolin is the best prophylactic antibiotic to prevent this complication. the goal of this study was to evaluate the effect of continuous and intermittent cefazolin for the prevention of superficial surgical site infection following off-pump coronary artery bypass (opcab). methods: this prospectiv...

(1) Background: Mechanical loading is an essential part of the function and maintenance joint. Despite importance intermittent mechanical loading, this factor rarely considered in preclinical models cartilage, limiting their translatability. The aim study was to investigate effects dynamic compression on extracellular matrix during long-term culture bovine cartilage explants. (2) Methods: Bovin...

PURPOSE The use of intermittent pneumatic compression, in addition to elastic bandages or stockings, accelerates the healing of leg ulcers in patients with severe chronic venous insufficiency (CVI). There is recent evidence that impulse compression of the plantar venous plexus reduces post-traumatic ankle swelling and prevents postoperative venous thromboembolism. The purpose of this study was ...

INTRODUCTION Diverticulosis coli is the most common disease of the colon in Western countries. Giant colonic diverticulum, defined as a colonic diverticulum measuring 4 cm in size or larger, represents an unusual manifestation of this common clinical entity. CASE PRESENTATION A 68-year-old Caucasian British woman with a history of intermittent lower abdominal mass, leg swelling and focal neur...

In a conventional cooling system, refrigerant superheating inside the compressor is largely responsible for overall energy losses, increasing the compression specific work and decreasing the cooling capacity. In heat pump applications, superheating not only affects the compression loss, but also the specific heating capacity of the system, since the inlet temperature of the condenser depends on...

UNLABELLED An impedance threshold valve (ITV) is a new airway adjunct for resuscitation that permits generation of a small vacuum in the chest during the recoil phase of chest compression. OBJECTIVES To explore in detail the expected magnitude and the hemodynamic mechanisms of circulatory augmentation by an ITV in Standard CPR. METHOD A 14-compartment mathematical model of the human cardiop...
