Background: People who have had a cardiac event are at increased risk of a subsequent event and death and are, therefore, the priority for preventive cardiology in Australia and elsewhere. Guidelines for physiological and lifestyle risk factors have been developed to encourage risk reduction as a means of secondary prevention. The aim of the present study was to investigate achievement of recommended risk factor targets in a sample of Australian cardiac patients.

Methods: We undertook a prospective, nonrandomized trial of kidney transplantation in HIV-infected candidates who had CD4+ T-cell counts of at least 200 per cubic millimeter and undetectable plasma HIV type 1 (HIV-1) RNA levels while being treated with a stable antiretroviral regimen. Post-transplantation management was provided in accordance with study protocols that defined prophylaxis against opportunistic infection, indications for biopsy, and acceptable approaches to immunosuppression, management of rejection, and antiretroviral therapy.
Purpose: Good cancer pain control requires appropriate assessment and treatment. The purpose of this study was to examine the relationships among physician, nurse practitioner, and nurse knowledge, documentation of assessment, treatment, and pain reduction in cancer patients seen in ambulatory settings.
Method: The study method included an assessment of pain knowledge of providers (physicians, nurse practitioners, and nurses) who worked in cancer clinics and a retrospective review of patients' records treated for cancer-related pain in their clinics.

Background: We hypothesized that chronic inhibition of epidermal growth factor receptor (EGFR) by cetuximab, a monoclonal anti-EGFR antibody, induces up-regulation of its ligands resulting in resistance and that microRNAs (miRs) play an important role in the ligand regulation in head and neck squamous cell carcinoma (HNSCC).
Methodology/principal Findings: Genome-wide changes in gene and miR expression were determined in cetuximab-sensitive cell line, SCC1, and its resistant derivative 1Cc8 using DNA microarrays and RT-PCR. The effects of differentially expressed EGFR ligands and miRs were examined by MTS, colony formation, ELISA, and western blot assays.
Circadian rhythms are innate 24-h cycles in behavioral and biochemical processes that permit physiological anticipation of daily environmental changes. Elucidating the relationship between activity rhythms and circadian patterns of gene expression may contribute to improved human and equine athletic performance. Six healthy, untrained mares were studied to determine whether locomotor activity behavior and skeletal muscle gene expression reflect endogenous circadian regulation.

We tested the hypothesis that islet isolation and transplantation activate innate immunity through TLR expressed on islets. Murine islets constitutively express TLR2 and TLR4, and TLR activation with peptidoglycan or LPS upregulates islet production of cytokines and chemokines.

Few studies have investigated the change in mood states, such as anger, fatigue and confusion, after coronary artery bypass graft surgery (CABGS). The aim of this study was to describe the progression of these mood states over time and to determine the factors associated with these trajectories. The Profile of Mood States (POMS) was administered to 182 CABGS patients prior to surgery and at two and six months post-operatively.

Here, we describe a patient with HNSCC who had complete response to methotrexate (MTX) after progressing on multiple cytotoxic agents, cetuximab, and AMG-479 (monoclonal antibody against insulin-like growth factor-1 receptor [IGF-1R]).
Methods: The clinical information was collected by a retrospective medical record review under an Institutional Review Board-approved protocol.
Objective: The complement system contributes to autoimmune injury, but its involvement in promoting the development of autoimmune diabetes is unknown. In this study, our goal was to ascertain the role of complement C3 in autoimmune diabetes.
Research Design And Methods: Susceptibility to diabetes development after multiple low-dose streptozotocin treatment in wild-type (WT) and C3-deficient mice was analyzed.
Background & Aims: While studies in animal models have linked Toll-like receptor (TLR) 4 signaling to the pathophysiology of ischemia/reperfusion (IR) injury and liver fibrosis, the relevance of TLR4 activation after human liver transplantation is unknown. The TLR4 single nucleotide polymorphism (SNP) D299G is situated within the extracellular domain and diminishes receptor binding to danger-associated molecular patterns.
Methods: We studied the influence of TLR4 D299G on IR injury and graft survival in 430 deceased donor LT recipients.
The complement system has been implicated in the pathogenesis of liver diseases. Human complement component C3 (C3) exists as 2 allotypes, fast (F) and slow (S). We conducted a study to address the influence of these alleles on ischemia-reperfusion (IR) injury and graft survival in liver transplant recipients.

Background: We hypothesized that a serum proteomic profile predictive of survival benefit in non-small cell lung cancer patients treated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI) reflects tumor EGFR dependency regardless of site of origin or class of therapeutic agent.
Methods: Pretreatment serum or plasma from 230 patients treated with cetuximab, EGFR-TKIs, or chemotherapy for recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) or colorectal cancer (CRC) were analyzed by mass spectrometry. Each sample was classified into "good" or "poor" groups using VeriStrat, and survival analyses of each cohort were done based on this classification.
Injured epithelial cells of the proximal tubule upregulate the glycoprotein kidney injury molecule 1 (KIM-1), suggesting its potential as a biomarker of incipient kidney allograft injury. It is unknown whether KIM-1 expression changes in kidney allografts with delayed graft function (DGF), which often follows ischemia-reperfusion injury. Here, we prospectively measured KIM-1 RNA and protein expression in preperfusion biopsies of 30 living- and 85 deceased-donor kidneys and correlated the results with histologic and clinical outcomes after transplantation.
