A Statement On Vemurafenib-Resistant Melanoma., Edward J Hartsough, A E Aplin Aug 2013

A Statement On Vemurafenib-Resistant Melanoma., Edward J Hartsough, A E Aplin

Department of Cancer Biology Faculty Papers

Despite recent advancements in the treatment of late-stage mutant BRAF (V600E/K) melanomas, a major hurdle continues to be acquired resistance to BRAF inhibitors such as vemurafenib. The mechanisms for resistance have proven to be heterogeneous, emphasizing the need to use broad therapeutic approaches. In this issue, the study "Stat3-targeted therapies overcome the acquired resistance to vemurafenib in melanomas" by Liu et al. proposes that signal transducer and activator of transcription 3 (STAT3)-paired box 3 (PAX3) signaling may be a mechanism that is used by melanomas to resist RAF inhibitors.

OBJECTIVE: To determine whether SMAD4 expression is associated with recurrence pattern after resection for pancreatic ductal adenocarcinoma (PDA).

BACKGROUND: SMAD4 expression status has been reported to be associated with patterns of failure in PDA, but studies have not examined recurrence patterns after resection.

METHODS: A tissue microarray was constructed including 127 patients with resected PDA and either short-term (<12 >months) or long-term (>30 months) survival. SMAD4 expression was evaluated by immunohistochemistry and categorized as present or lost in tumor cells. Conventional pathologic features (lymph node metastases, positive resection margin, poor grade, and tumor size) were recorded, and disease-specific outcomes …


Body Mri Artifacts In Clinical Practice: A Physicist's And Radiologist's Perspective., Martin J Graves, Donald Mitchell Aug 2013

Body Mri Artifacts In Clinical Practice: A Physicist's And Radiologist's Perspective., Martin J Graves, Donald Mitchell

Department of Radiology Faculty Papers

The high information content of MRI exams brings with it unintended effects, which we call artifacts. The purpose of this review is to promote understanding of these artifacts, so they can be prevented or properly interpreted to optimize diagnostic effectiveness. We begin by addressing static magnetic field uniformity, which is essential for many techniques, such as fat saturation. Eddy currents, resulting from imperfect gradient pulses, are especially problematic for new techniques that depend on high performance gradient switching. Nonuniformity of the transmit radiofrequency system constitutes another source of artifacts, which are increasingly important as magnetic field strength increases. Defects in …

Hippocampal Functional Connectivity Patterns During Spatial Working Memory Differ In Right Versus Left Temporal Lobe Epilepsy., Gaelle Eve Doucet, Karol Osipowicz, Ashwini Sharan Md, Michael R Sperling, Joseph I Tracy

Department of Neurology Faculty Papers

Temporal lobe epilepsy (TLE), affecting the medial temporal lobe, is a disorder that affects not just episodic memory but also working memory (WM). However, the exact nature of hippocampal-related network activity in visuospatial WM remains unclear. To clarify this, we utilized a functional connectivity (FC) methodology to investigate hippocampal network involvement during the encoding phase of a functional magnetic resonance imaging (fMRI) visuospatial WM task in right and left TLE patients. Specifically, we assessed the relation between FC within right and left hippocampus-seeded networks, and patient performance (rate of correct responses) during the encoding phase of a block span WM …

Altered Drainage Patterns In Patients With Melanoma And Previous Axillary Dissection., Caitlyn M. Johnson, Charles Intenzo, Michael Mastrangelo, Kendra Feeney, Adam C. Berger

Department of Surgery Faculty Papers

The incidence of melanoma is increasing rapidly in the United States. Sentinel lymph node biopsy is an important diagnostic tool in the treatment and staging of melanoma. However, many patients with melanoma will have had lymph node surgery for previous melanoma or breast cancer. We set out to examine alterations in drainage patterns in patients with previous axillary dissection for breast cancer. We reviewed four patients with truncal and/or extremity melanomas and examined their lymphoscintigraphy and drainage patterns. Three patients with truncal melanoma mapped to cervical lymph nodes and a fourth patient with an arm melanoma mapped to her previously …

Department of Surgery Faculty Papers

Conventional algorithms for diagnosis and treatment of gastrointestinal bleeding (GIB) in patients with nonpulsatile ventricular assist devices (VADs) may take days to perform while patients require transfusions. We developed a new algorithm based on deep overtube-assisted enteroscopy (DOAE) to facilitate a rapid diagnosis and treatment. From 2004 to 2012, 84 patients who underwent VAD placement in our institution, were evaluated for episodes of GIB. Our new algorithm for the management of GIB using DOAE was evaluated by dividing the episodes into three groups: group A (traditional management without enteroscopy), group B (traditional management with enteroscopy performed >24 hours after presentation), …

Strategies For Anti-Fibrotic Therapies., Joel Rosenbloom, Fabian A. Mendoza, Md, Sergio A. Jimenez

Jefferson Institute of Molecular Medicine Papers and Presentations

The fibrotic diseases encompass a wide spectrum of entities including such multisystemic diseases as systemic sclerosis, nephrogenic systemic fibrosis and sclerodermatous graft versus host disease, as well as organ-specific disorders such as pulmonary, liver, and kidney fibrosis. Collectively, given the wide variety of affected organs, the chronic nature of the fibrotic processes, and the large number of individuals suffering their devastating effects, these diseases pose one of the most serious health problems in current medicine and a serious economic burden to society. Despite these considerations there is currently no accepted effective treatment. However, remarkable progress has been achieved in the …

Alcohol And The Heart: To Abstain Or Not To Abstain?, Rajesh Movva, Md, Mrcp, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

Alcohol has been consumed by most societies over the last 7000 years. Abraham Lincoln said "It has long been recognized that the problems with alcohol relate not to the use of a bad thing, but to the abuse of a good thing." Light to moderate alcohol consumption reduces the incidence of coronary heart disease (CHD), ischemic stroke, peripheral arterial disease, CHD mortality, and all-cause mortality, especially in the western populations. However, heavy alcohol consumption is detrimental causing cardiomyopathy, cardiac arrhythmias, hepatic cirrhosis, pancreatitis, and hemorrhagic stroke. In this article, we review the effects of alcohol on CHD, individual cardiovascular risk …


Glucose Stimulation Induces Dynamic Change Of Mitochondrial Morphology To Promote Insulin Secretion In The Insulinoma Cell Line Ins-1e., Bong Sook Jhun, Hakjoo Lee, Zheng-Gen Jin, Yisang Yoon Apr 2013

Glucose Stimulation Induces Dynamic Change Of Mitochondrial Morphology To Promote Insulin Secretion In The Insulinoma Cell Line Ins-1e., Bong Sook Jhun, Hakjoo Lee, Zheng-Gen Jin, Yisang Yoon

Center for Translational Medicine Faculty Papers

Fission and fusion of mitochondrial tubules are the major processes regulating mitochondrial morphology. However, the physiological significance of mitochondrial shape change is poorly understood. Glucose-stimulated insulin secretion (GSIS) in pancreatic β-cells requires mitochondrial ATP production which evokes Ca(2+) influx through plasma membrane depolarization, triggering insulin vesicle exocytosis. Therefore, GSIS reflects mitochondrial function and can be used for evaluating functional changes associated with morphological alterations of mitochondria. Using the insulin-secreting cell line INS-1E, we found that glucose stimulation induced rapid mitochondrial shortening and recovery. Inhibition of mitochondrial fission through expression of the dominant-negative mutant DLP1-K38A eliminated this dynamic mitochondrial shape change …

Department of Cancer Biology Faculty Papers

Fibroblast growth factor-inducible protein 14 (Fn14), the cell surface receptor for tumor necrosis factor-like weak inducer of apoptosis (TWEAK), is overexpressed in various human solid tumor types and can be a negative prognostic indicator. We detected Fn14 expression in ∼60% of the melanoma cell lines we tested, including both B-Raf WT and B-Raf(V600E) lines. Tumor tissue microarray analysis indicated that Fn14 expression was low in normal skin, but elevated in 173/190 (92%) of primary melanoma specimens and in 86/150 (58%) of melanoma metastases tested. We generated both a chemical conjugate composed of the recombinant gelonin (rGel) toxin and the anti-Fn14 …

Preparation And Technical Considerations For Percutaneous Cannulation For Veno-Arterial Extracorporeal Membrane Oxygenation., Kathleen Lamb, Hitoshi Hirose, Nicholas C. Cavarocchi Mar 2013

Preparation And Technical Considerations For Percutaneous Cannulation For Veno-Arterial Extracorporeal Membrane Oxygenation., Kathleen Lamb, Hitoshi Hirose, Nicholas C. Cavarocchi

Department of Surgery Faculty Papers

BACKGROUND: The most frequent limb complications from peripheral veno-arterial extracorporeal membrane oxygenation (VA-ECMO) are limb ischemia and localized bleeding. To minimize these risks, perfusion of the distal limb with peripheral percutaneous cannulation was done.

TECHNIQUE: Percutaneous cannulation with a distal perfusion port was performed in all patients. During the VA-ECMO, distal limb perfusion was monitored using near-infrared spectroscopy to assess tissue oxygenation. At the decannulation, patch angioplasty was performed to prevent the development of narrowing of the artery at the cannulation site.

CONCLUSIONS: Using our standard technique, we have not experienced any limb loss related to ischemia or bleeding.

The Adipose Tissue Production Of Adiponectin Is Increased In End-Stage Renal Disease., Maria P Martinez Cantarin, Scott A Waldman, Cataldo Doria, Adam M Frank, Warren R Maley, Carlo B Ramirez, Scott W Keith, Bonita Falkner

Department of Medicine Faculty Papers

Adiponectin has antidiabetic properties, and patients with obesity, diabetes, and insulin resistance have low plasma adiponectin levels. However, although kidney disease is associated with insulin resistance, adiponectin is elevated in end-stage renal disease. Here we determine whether adipose tissue production of adiponectin is increased in renal disease in a case-control study of 36 patients with end-stage renal disease and 23 kidney donors. Blood and tissue samples were obtained at kidney transplantation and donation. The mean plasma adiponectin level was significantly increased to 15.6 mg/ml in cases compared with 8.4 mg/ml in controls. Plasma levels of the inflammatory adipokines tumor necrosis …

Major Perioperative Morbidity Does Not Affect Long-Term Survival In Patients Undergoing Esophagectomy For Cancer Of The Esophagus Or Gastroesophageal Junction., Brent T Xia, Ernest L Rosato, Karen A Chojnacki, Albert G. Crawford, Benny Weksler, Adam C. Berger

Department of Surgery Faculty Papers

INTRODUCTION: The incidence of cancer of the esophagus/GE junction is dramatically increasing but continues to have a dismal prognosis. Esophagectomy provides the best opportunity for long-term cure but is hampered by increased rates of perioperative morbidity. We reviewed our large institutional experience to evaluate the impact of postoperative complications on the long-term survival of patients undergoing resection for curative intent.

METHODS: We identified 237 patients who underwent esophagogastrectomy, with curative intent, for cancer between 1994 and 2008. Complications were graded using the previously published Clavien scale. Survival was calculated using Kaplan-Meier methodology and survival curves were compared using log-rank tests. …


Distribution Of Dyssynchrony In Subjects With No Known Cardiac Disease And Comparison Of Velocity Vector Imaging To Color-Coded Tissue Doppler Imaging., Anoop C Parameswaran, Bhaskar Purushottam, Aman Amanullah, Vincent M. Figueredo, M.D. Feb 2013

Distribution Of Dyssynchrony In Subjects With No Known Cardiac Disease And Comparison Of Velocity Vector Imaging To Color-Coded Tissue Doppler Imaging., Anoop C Parameswaran, Bhaskar Purushottam, Aman Amanullah, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

Data on the distribution of dyssynchrony in subjects with normal ejection fraction (EF) and normal QRS are scarce. We studied 100 subjects with no known cardiac disease (52% male, mean age 60 ± 17 years) using velocity vector imaging (VVI). Seventeen percent had septal to lateral (S-L) wall longitudinal delay >75 msec, 63% of subjects had S-L wall radial delay >75 msec, and 25% had a circumferential opposing wall delay >100 msec. Those with circumferential opposing wall delay of >100 msec had a lower EF (57 ± 5% vs. 62 ± 5%, P < 0.05). In an additional group of 33 patients, we compared the longitudinal dyssynchrony parameters as assessed by VVI and tissue Doppler imaging (TDI) and found them to be comparable. In conclusion, we find significant variation in time to peak velocities in subjects with no known cardiac disease, who had a normal left ventricular ejection fraction and QRS duration. VVI is comparable to TDI.
