Economic considerations in abdominal transplantation.

Care for end-stage organ failure through transplant is one of the landmark accomplishments of the modern medicine. At the same time, organ transplant is a resource-intensive service that has been under increasing scrutiny in this era of cost containment. A detailed understanding of the economic implications of organ quality, recipient characteristics, and allocation policy is vital for the transplant professionals.

Measuring Clinical Productivity.

Productivity measurements have been used to evaluate and compare physicians and physician practices. Anesthesiology is unique in that factors outside anesthesiologist control impact opportunity for revenue generation and make comparisons between providers and facilities challenging. This article uses data from the multicenter University of Pittsburgh Physicians Department of Anesthesiology to demonstrate factors influencing productivity opportunity by surgical facility, between department divisions and subspecialties within multispecialty divisions, and by individuals within divisions.

The benefits of ultrasound-guided continuous sensory nerve blockade in the setting of burn injury: a case report of bilateral continuous superficial peroneal nerve blockade in a patient with severe sleep apnea.

The management of pain after burn injuries is a clinical challenge magnified in patients with significant comorbidities. Presently, burn pain is treated via a wide variety of modalities, including systemic pharmacotherapy and regional analgesia. Although the latter can provide effective pain control in patients with burn injuries, it is relatively underused.

Luciferase immunoprecipitation systems for measuring antibodies in autoimmune and infectious diseases.

Antibody profiles have the potential to revolutionize personalized medicine by providing important information related to autoimmunity against self-proteins and exposure to infectious agents. One immunoassay technology, luciferase immunoprecipitation systems (LIPS), harnesses light-emitting recombinant proteins to generate robust, high-quality antibody data often spanning a large dynamic range of detection. Here, we describe the general format of LIPS and discuss studies using the technology to measure autoantibodies in several human autoimmune diseases including type 1 diabetes, Sjögren's syndrome, systemic lupus erythematosus, and immunodeficiencies secondary to anticytokine autoantibodies.

Nociception and inflammatory hyperalgesia evaluated in rodents using infrared laser stimulation after Trpv1 gene knockout or resiniferatoxin lesion.

TRPV1 is expressed in a subpopulation of myelinated Aδ and unmyelinated C-fibers. TRPV1+ fibers are essential for the transmission of nociceptive thermal stimuli and for the establishment and maintenance of inflammatory hyperalgesia. We have previously shown that high-power, short-duration pulses from an infrared diode laser are capable of predominantly activating cutaneous TRPV1+ Aδ-fibers.

Commercial multiplex technologies for the microbiological diagnosis of sepsis.

In patients with suspected sepsis, rapid and accurate diagnosis of the causative infectious agent is critical. Although clinicians often use empiric antimicrobial therapy until the blood cultures are available to potentially adjust treatment, this approach is often not optimum for patient care. Recently, several commercial molecular multiplex technologies have shown promise for fast and comprehensive diagnosis of microorganisms and their antimicrobial resistance signatures.

Extrapancreatic autoantibody profiles in type I diabetes.

Type I diabetes (T1D) is an autoimmune disease characterized by destruction of insulin-producing β-cells in the pancreas. Although several islet cell autoantigens are known, the breadth and spectrum of autoantibody targets has not been fully explored. Here the luciferase immunoprecipitation systems (LIPS) antibody profiling technology was used to study islet and other organ-specific autoantibody responses in parallel.

Positive allosteric modulation of TRPV1 as a novel analgesic mechanism.

Background: The prevalence of long-term opiate use in treating chronic non-cancer pain is increasing, and prescription opioid abuse and dependence are a major public health concern. To explore alternatives to opioid-based analgesia, the present study investigates a novel allosteric pharmacological approach operating through the cation channel TRPV1. This channel is highly expressed in subpopulations of primary afferent unmyelinated C- and lightly-myelinated Aδ-fibers that detect low and high rates of noxious heating, respectively, and it is also activated by vanilloid agonists and low pH.
