Imp3 Expression Is Associated With Poor Outcome And Epigenetic Deregulation In Intrahepatic Cholangiocarcinoma, Yuanyuan Gao, Michelle Yang, Zhong Jiang, Bruce A. Woda, Arthur M. Mercurio, Jianjie Qin, Xinli Huang, Feng Zhang

Arthur M. Mercurio

IMP3 is a fetal protein not expressed in normal adult tissues. IMP3 is an oncoprotein and a useful biomarker for a variety of malignancies and is associated with reduced overall survival of a number of them. IMP3 expression and its prognostic value for patients with intrahepatic cholangiocarcinoma (ICC) have not been well investigated. The molecular mechanism underlying IMP3 expression in human cancer cells remains to be elucidated. Here we investigated IMP3 expression in ICC and adjacent nonneoplastic liver in 72 unifocal primary ICCs from a single institute by immunohistochemistry, immunoblotting, and real-time polymerase chain reaction. IMP3 was specifically expressed in …

Distribution Of Health Care Expenditures For Hiv-Infected Patients, Ray Y. Chen, Neil A. Accortt, Andrew O. Westfall, Michael J. Mugavero, James L. Raper, Gretchen A. Cloud, Beth K. Stone, Jerome Carter, Stephanie Call, Maria Pisu, Jeroan J. Allison, Michael S. Saag

BACKGROUND: Health care expenditures for persons infected with human immunodeficiency virus (HIV) in the United State determined on the basis of actual health care use have not been reported in the era of highly active antiretroviral therapy.

METHODS: Patients receiving primary care at the University of Alabama at Birmingham HIV clinic were included in the study. All encounters (except emergency room visits) that occurred within the University of Alabama at Birmingham Hospital System from 1 March 2000 to 1 March 2001 were analyzed. Medication expenditures were determined on the basis of 2001 average wholesale price. Hospitalization expenditures were determined on …

Trends In Aids-Defining And Non-Aids-Defining Malignancies Among Hiv-Infected Patients: 1989-2002, Roger Bedimo, Ray Y. Chen, Neil A. Accortt, James L. Raper, Carol Linn, Jeroan J. Allison, John Dubay, Michael S. Saag, Craig J. Hoesley

In a comparison of rates of acquired immunodeficiency syndrome (AIDS)-defining malignancies (ADMs) for 1989-1996 versus 1997-2002, we found a decrease in ADMs (rate ratio, 0.31; P<.0001) and a significant increase in non-AIDS-defining malignancies (non-ADMs; rate ratio, 10.87; P<.0002). The mean CD4 cell count was lower among patients with ADMs than among those with non-ADMs. A longer duration of survival during highly active antiretroviral therapy might explain the increasing incidence of non-ADMs.

Temporal Trends In Cardiogenic Shock Complicating Acute Myocardial Infarction, Robert J. Goldberg, Navid A. Samad, Jorge L. Yarzebski, Jerry H. Gurwitz, Carol Bigelow, Joel M. Gore

BACKGROUND: Limited information is available on trends in the incidence of and mortality due to cardiogenic shock complicating acute myocardial infarction. We studied the incidence of cardiogenic shock complicating acute myocardial infarction and in-hospital death rates among patients with this condition in a single community from 1975 through 1997. METHODS: We conducted an observational study of 9076 residents of metropolitan Worcester, Massachusetts, who were hospitalized with confirmed acute myocardial infarction in all local hospitals during 11 one-year periods between 1975 and 1997. Our study included periods before and after the advent of reperfusion therapy. RESULTS: The incidence of cardiogenic shock …

Factors Related To Declining Luteal Function In Women During The Menopausal Transition, Nanette Santoro, Sybil L. Crawford, Bill Lasley, J. L. Luborsky, Karen A. Matthews, Daniel Mcconnell, John F.

CONTEXT: Reproductive hormones are incompletely characterized during the menopause transition (MT). Hypothesis: Increased anovulation and decreased progesterone accompany progress through the MT. DESIGN: The Daily Hormone Study (DHS) of the Study of Women's Health Across the Nation (SWAN) included 848 women aged 43-53 yr at baseline who collected daily urine for one cycle or up to 50 d annually for 3 yr. MAIN OUTCOME MEASURES: LH, FSH, estrone conjugates, and pregnanediol glucuronide levels were assessed. Cycles were classified by presumed luteal (ovulatory) status and bleeding. Hormones were related to time in study, age, menopausal status, and selected variables. RESULTS: Ovulatory-appearing …

Design And Methods For A Randomized Clinical Trial Treating Comorbid Obesity And Major Depressive Disorder, Kristin L. Schneider, Jamie S. Bodenlos, Yunsheng Ma, Barbara C. Olendzki, Jessica Oleski, Philip A. Merriam, Sybil L. Crawford, Ira S. Ockene, Sherry L. Pagoto

Sybil L. Crawford

BACKGROUND: Obesity is often comorbid with depression and individuals with this comorbidity fare worse in behavioral weight loss treatment. Treating depression directly prior to behavioral weight loss treatment might bolster weight loss outcomes in this population, but this has not yet been tested in a randomized clinical trial. METHODS AND DESIGN: This randomized clinical trial will examine whether behavior therapy for depression administered prior to standard weight loss treatment produces greater weight loss than standard weight loss treatment alone. Obese women with major depressive disorder (N = 174) will be recruited from primary care clinics and the community and randomly …

Distinct Toll-Like Receptor Expression In Monocytes And T Cells In Chronic Hcv Infection, Angela Dolganiuc, Catherine Garcia, Karen Kodys, Gyongyi Szabo

Gyongyi Szabo

AIM: Hepatitis C virus often establishes chronic infections. Recent studies suggest that viral and bacterial infections are more common in HCV-infected patients compared to controls. Pathogens are recognized by Toll-like receptors (TLRs) to shape adaptive and innate immune responses.

METHODS: In this study, to assess the ability of HCV-infected host to recognize invading pathogens, we investigated Toll-like receptor expression in innate (monocytes) and adaptive (T cells) immune cells by real-time PCR.

RESULTS: We determined that RNA levels for TLRs 2, 6. 7, 8, 9 and 10 mRNA levels were upregulated in both monocytes and T cells in HCV-infected patients compared …
