OBJECTIVES: We analyzed the infection burden associated with the implantation of cardiac implantable electrophysiological devices (CIEDs) in the United States for the years 1993 to 2008.

BACKGROUND: Recent data suggest that the rate of infection following CIED implantation may be increasing.

METHODS: The Nationwide Inpatient Sample (NIS) discharge records were queried between 1993 and 2008 using the 9th Revision of the International Classification of Diseases (ICD-9-CM). CIED infection was defined as either: 1) ICD-9 code for device-related infection (996.61) and any CIED procedure or removal code; or 2) CIED procedure code along with systemic infection. Patient health profile was evaluated …

Bionic Technologies Transforming The Science Of Healthcare Delivery, Scott A. Waldman , M.D., Ph.D, Andre Terzic , M.D., Ph.D

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Individualization of patient care is creating an envisioned future in which practitioners wield a new doctor’s bag deploying individual molecular, genetic, cellular, and systems profiles. These emerging tools are refining traditional paradigms of disease palliation into nuanced patient management algorithms employing prognostic risk stratification, therapeutic response prediction, and adverse event avoidance. Advancing technologies are enabling a shift to more proximal nodes along the continuum of pathobiology. Innovations in biomarker platforms, genomic profiling, and molecular imaging reveal the earliest stages of pathophysiology, limiting systems disruption to cells and tissues while preserving integrated organ function, enabling risk mitigation and disease prevention. At …

Expression Of Aldehyde Dehydrogenase In Dysplastic Lesions Arising From Inflammatory Bowel Disease, Adam D. Toll, Bruce M. Boman, Juan P. Palazzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Conclusion: Our study demonstrates ALDH1 is significantly expressed in dysplatic lesions arising from IBD. ALDH1-expression in cancer stem cells suggest an important causative role in the progression to cancer in IBD. Although we found high sensitivity for dysplasia, the specificity was poor. In addition to neoplasia, ALDH1-expressing stem cells proliferate in response to chronic inflammation, accounting for the cases of inflammatory atypia with positive ALDHI1 expression.

Epidermal Growth Factor Receptor Overexpression In Resected Pancreatic Cancer, Amit Mahipal, Mary J. Mcdonald, Agnieszka Witkiewicz, Brian I. Carr

Conclusions:

Membrane EGFR overexpression is associated with poorer clinical outcomes in patients with pancreatic cancer receiving adjuvant therapy post resection.

Cytoplasmic EGFR overexpression is not associated with clinical outcomes.

Poster presented at "Medicine Meets Virtual Reality" conference February 8-12, 2011 in Newport Beach, California.

Conclusions:

Turning 2D CT/PET slices into 3D objects assists in understanding the topology surrounding tumor masses. Incorporating the visual and physical characteristics of a patient’s anatomy will provide surgeons with an informative pre-operative tool to plan and practice the operation before the first incision. Including haptic feedback provides a familiar 'feel' to surgeons as they palpate the target organ, trying to locate the tumor and determine how large a margin of resection will be needed. The development of genetic PET imaging and contrast CT into …

Comparative Gender Analysis Of The Efficacy And Safety Of Atazanavir/Ritonavir And Lopinavir/Ritonavir At 96 Weeks In The Castle Study., Kathleen E Squires, Margaret Johnson, Rong Yang, Jonathan Uy, Louise Sheppard, Judith Absalon, Donnie Mcgrath

Department of Medicine Faculty Papers

OBJECTIVES: To examine whether the overall results of the CASTLE study pertain to both genders, we analysed the efficacy and safety of atazanavir/ritonavir and lopinavir/ritonavir in 277 female and 606 male patients in the open-label, multinational trial over 96 weeks. The trial is registered with ClinicalTrials.gov, number NCT00272779.

METHODS: Treatment-naive patients aged ≥ 18 years with HIV-1 RNA ≥ 5000 copies/mL were randomized to receive either atazanavir/ritonavir 300/100 mg once daily or lopinavir/ritonavir 400/100 mg twice daily, with fixed-dose tenofovir/emtricitabine 300/200 mg once daily.

RESULTS: At week 96, confirmed virological response rates (HIV RNA <50 copies>/mL; intent-to-treat analysis) were higher in …

Protein Modification By Arginylation, Hideko Kaji, Akira Kaji

Department of Biochemistry and Molecular Biology Faculty Papers

The modification of protein by arginine catalyzed by arginyltransferases (ATE1) described by the Kashina group in this issue shows that arginylation of protein occurs widely in biology and is being recognized as a key regulatory reaction such as phosphorylation of proteins (Wang et al., 2011).

An Evidence-Based Review Of Fat Modifying Supplemental Weight Loss Products., Amy M Egras, William R Hamilton, Thomas L Lenz, Michael S Monaghan

College of Pharmacy Faculty Papers

Objective. To review the literature on fat modifying dietary supplements commonly used for weight loss. Methods. Recently published randomized, placebo-controlled trials were identified in PubMed, MEDLINE, International Pharmaceutical Abstracts, Cochrane Database, and Google Scholar using the search terms dietary supplement, herbal, weight loss, obesity, and individual supplement names. Discussion. Data for conjugated linoleic acid (CLA), Garcinia cambogia, chitosan, pyruvate, Irvingia gabonensis, and chia seed for weight loss were identified. CLA, chitosan, pyruvate, and Irvingia gabonensis appeared to be effective in weight loss via fat modifying mechanisms. However, the data on the use of these products is limited. Conclusion. Many obese …
