Acetabular Components In Total Hip Arthroplasty: Is There Evidence That Cementless Fixation Is Better?, Nader Toossi, Bahar Adeli, Andrew J Timperley, Fares S Haddad, Mitchell Maltenfort, Javad Parvizi

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: The use of cementless acetabular components in total hip arthroplasty has gained popularity over the past decade. Most total hip arthroplasties being performed in North America currently use cementless acetabular components. The objective of this systematic review and meta-analysis was to compare the survivorship and revision rate of cemented and cementless acetabular components utilized in total hip arthroplasty.

METHODS: A primary literature search in PubMed identified 3488 articles, of which 3407 did not meet the inclusion criteria and were excluded. Only English-language articles on either the survivorship or revision rate of primary total hip arthroplasty at a minimum of …


Synchronous And Asynchronous Theta And Gamma Activity During Episodic Memory Formation., John F Burke, Kareem A Zaghloul, Joshua Jacobs, Ryan B Williams, Michael R Sperling, Ashwini D Sharan, Michael J Kahana Jan 2013

Synchronous And Asynchronous Theta And Gamma Activity During Episodic Memory Formation., John F Burke, Kareem A Zaghloul, Joshua Jacobs, Ryan B Williams, Michael R Sperling, Ashwini D Sharan, Michael J Kahana

Department of Neuroscience Faculty Papers

To test the hypothesis that neural oscillations synchronize to mediate memory encoding, we analyzed electrocorticographic recordings taken as 68 human neurosurgical patients studied and subsequently recalled lists of common words. To the extent that changes in spectral power reflect synchronous oscillations, we would expect those power changes to be accompanied by increases in phase synchrony between the region of interest and neighboring brain areas. Contrary to the hypothesized role of synchronous gamma oscillations in memory formation, we found that many key regions that showed power increases during successful memory encoding also exhibited decreases in global synchrony. Similarly, cortical theta activity …

Diet And Nutrition In Cancer Survivorship And Palliative Care., Anthony J Bazzan, Andrew B Newberg, William C Cho, Daniel A Monti Jan 2013

Diet And Nutrition In Cancer Survivorship And Palliative Care., Anthony J Bazzan, Andrew B Newberg, William C Cho, Daniel A Monti

Marcus Institute of Integrative Health Faculty Papers

The primary goal of palliative cancer care is typically to relieve suffering and improve quality of life. Most approaches to diet in this setting have focused only on eating as many calories as possible to avoid cachexia. However, as the concept of palliative care has evolved to include all aspects of cancer survivorship and not just end of life care, there is an increasing need to thoughtfully consider diet and nutrition approaches that can impact not only quality of life but overall health outcomes and perhaps even positively affect cancer recurrence and progression. In this regard, there has been a …

Dynamic Recruitment Of Micrornas To Their Mrna Targets In The Regenerating Liver., Jonathan Schug, Lindsay B Mckenna, Gabriel Walton, Nicholas Hand, Sarmistha Mukherjee, Kow Essuman, Zhongjie Shi, Yan Gao, Karen Markley, Momo Nakagawa, Vasumathi Kameswaran, Anastassios Vourekas, Joshua R Friedman, Klaus H Kaestner, Linda E Greenbaum

Department of Cancer Biology Faculty Papers

BACKGROUND: Validation of physiologic miRNA targets has been met with significant challenges. We employed HITS-CLIP to identify which miRNAs participate in liver regeneration, and to identify their target mRNAs.

RESULTS: miRNA recruitment to the RISC is highly dynamic, changing more than five-fold for several miRNAs. miRNA recruitment to the RISC did not correlate with changes in overall miRNA expression for these dynamically recruited miRNAs, emphasizing the necessity to determine miRNA recruitment to the RISC in order to fully assess the impact of miRNA regulation. We incorporated RNA-seq quantification of total mRNA to identify expression-weighted Ago footprints, and developed a microRNA …

Dual Fluorescent Molecular Substrates Selectively Report The Activation, Sustainability And Reversibility Of Cellular Pkb/Akt Activity., Duanwen Shen, Mingfeng Bai, Rui Tang, Baogang Xu, Xiaoming Ju, Richard Pestell, Samuel Achilefu

Department of Cancer Biology Faculty Papers

Using a newly developed near-infrared (NIR) dye that fluoresces at two different wavelengths (dichromic fluorescence, DCF), we discovered a new fluorescent substrate for Akt, also known as protein kinase B, and a method to quantitatively report this enzyme's activity in real time. Upon insulin activation of cellular Akt, the enzyme multi-phosphorylated a single serine residue of a diserine DCF substrate in a time-dependent manner, culminating in monophospho- to triphospho-serine products. The NIR DCF probe was highly selective for the Akt1 isoform, which was demonstrated using Akt1 knockout cells derived from MMTV-ErbB2 transgenic mice. The DCF mechanism provides unparalleled potential to …


Retro-Aortic Left Renal Vein, Joann Aichroth, Rdms, Traci B. Fox, Ms, Rt(R), Rdms, Rvt Jan 2013

Retro-Aortic Left Renal Vein, Joann Aichroth, Rdms, Traci B. Fox, Ms, Rt(R), Rdms, Rvt

Department of Radiologic Sciences Faculty Papers

The term retro-aortic left renal vein (RLRV) is defined as the left renal vein coursing posterior to the abdominal aorta. RLRV is an uncommon condition in which the left renal vein passes posterior to the abdominal aorta and anterior to the vertebrae. RLRV may lead to left renal vein hypertension (LRVH) syndrome, which is also known as Nutcracker syndrome. Nutcracker syndrome (NCS) is a condition in which the left renal vein is compressed causing hypertension of the vessel. RLRV and Nutcracker syndrome are vascular anomalies considered to be of clinical importance especially during surgical procedures of the renal vasculature.

Tracking Transplanted Bone Marrow Stem Cells And Their Effects In The Rat Mcao Stroke Model., Gregory V Goldmacher, Rena Nasser, Daniel Y Lee, Sargon Yigit, Robert Rosenwasser, Lorraine Iacovitti

Farber Institute for Neuroscience Faculty Papers

In this study, rat bone marrow stromal stem cells (BMSCs) were tracked after IV administration to rats with experimental stroke caused by middle cerebral artery occlusion (MCAO). In addition, the effects of BMSC treatment on blood cell composition, brain glia and sensorimotor behavior was studied and compared to that which occurred spontaneously during the normal recovery process after stroke. We found that the vast majority of radiolabeled or fluorescently labeled BMSCs traveled to and remained in peripheral organs (lungs, spleen, liver) 3 days after IV injection in the MCAO rat. Once in the circulation, BMSCs also produced rapid alterations in …


Secondary Membranous Nephropathy Associated With Guillain-Barré Syndrome., Edward J Filippone, Mitul Kanzaria, Rodney Bell, Eric Newman, John L Farber Jan 2013

Secondary Membranous Nephropathy Associated With Guillain-Barré Syndrome., Edward J Filippone, Mitul Kanzaria, Rodney Bell, Eric Newman, John L Farber

Department of Medicine Faculty Papers

Membranous nephropathy (MN) is one of the most common causes of nephrotic syndrome (NS) in adults. It may be primary, usually mediated by IgG4 anti-phospholipase A2 autoantibodies or secondary to various other conditions. Guillain- Barré syndrome (GBS) has been associated with MN, but a cause and effect relation has not been proven. We present a case of concurrent development of GBS and severe NS, with renal biopsy demonstrating MN. IgG4 stain was negative, indicating that most likely, the MN was secondary and probably caused by the underlying GBS.


Advancing Maternal Survival In The Global Context: Are Our Strategies Working?, Omar A Khan, Richard Derman, Nancy L Sloan Jan 2013

Advancing Maternal Survival In The Global Context: Are Our Strategies Working?, Omar A Khan, Richard Derman, Nancy L Sloan

Department of Family & Community Medicine Faculty Papers

There have been significant gains in improving maternal mortality over the last two decades. Researchers have suggested a variety of interventions and mechanisms to explain these improvements. While it is likely that much of what has been done in research and programs has contributed to this decline, the evidence regarding what works in the settings in which women deliver continues to face many challenges. We review the evidence for these improvements and suggest that there remain areas to focus on, particularly the births which currently take place in an unsupervised or substandard environments. We highlight the main areas where more …

Should We Use Preoperative Epoetin-Α In The Mildly Anemic Patient Undergoing Simultaneous Total Knee Arthroplasty?, Lawrence A Delasotta, Fabio Orozco, S Mehdi Jafari, Jamie L Blair, Alvin Ong

Rothman Institute Papers

Simultaneous knee arthroplasty is associated with significant blood loss. To prevent transfusion, three preoperative doses of epoetin-α were offered to mildly anemic simultaneous knee arthroplasty patients. A retrospective review, using ICD-9 codes, identified twenty patients from 2007-2009. Epoetin-α increased hemoglobin levels preoperatively (12.6 to 13.9, p


Aortic Dissection Presenting As Gait Disturbance: A Case Report., Michael Estreicher, Joseph Portale, Bernard Lopez Jan 2013

Aortic Dissection Presenting As Gait Disturbance: A Case Report., Michael Estreicher, Joseph Portale, Bernard Lopez

Department of Emergency Medicine Faculty Papers

Emergency medicine dogma traditionally teaches that aortic dissection presents as tearing chest pain, radiating to the back. This case report describes a 55 year old woman presenting with a left homonymous hemianopsia and resultant gait disturbance. Initial head CT demonstrated a right parietal infarct, and chest radiograph demonstrated a markedly widened mediastinum. Acute Stanford Type A aortic dissection was subsequently confirmed. This report provides further evidence for atypical, painless presentations of aortic dissection. Given recent literature on the increasing prevalence of painless dissection, the disease entity should be included in the differential diagnosis for stroke, and a simple portable chest …

Department of Medicine Faculty Papers

OBJECTIVE: There is emerging evidence from animal studies suggesting a key role for methylation in the pathogenesis of essential hypertension. However, to date, very few studies have investigated the role of methylation in the development of human hypertension, and none has taken a genome-wide approach. Based on the recent studies that highlight the involvement of inflammation in the development of hypertension, we hypothesize that changes in DNA methylation of leukocytes are involved in the pathogenesis of hypertension.

METHOD & RESULTS: We conducted a genome-wide methylation analysis on 8 hypertensive cases and 8 normotensive age-matched controls aged 14-23 years and performed …

Inhibitory Effect Of Matrine On Blood-Brain Barrier Disruption For The Treatment Of Experimental Autoimmune Encephalomyelitis., Su Zhang, Quan-Cheng Kan, Yuming Xu, Guang-Xian Zhang, Lin Zhu

Department of Neurology Faculty Papers

Dysfunction of the blood-brain barrier (BBB) is a primary characteristic of experimental autoimmune encephalomyelitis (EAE), an experimental model of multiple sclerosis (MS). Matrine (MAT), a quinolizidine alkaloid derived from the herb Radix Sophorae Flave, has been recently found to suppress clinical EAE and CNS inflammation. However, whether this effect of MAT is through protecting the integrity and function of the BBB is not known. In the present study, we show that MAT treatment had a therapeutic effect comparable to dexamethasone (DEX) in EAE rats, with reduced Evans Blue extravasation, increased expression of collagen IV, the major component of the basement …

Kimmel Cancer Center Faculty Papers

Endothelial Cell Dysfunction (ECD) is a recognized harbinger of a host of chronic cardiovascular diseases. Using a mouse model of ECD triggered by treatment with L-Nω-methylarginine (L-NMMA), we previously demonstrated that renal microvasculature displays a perturbed protein profile, including diminished expression of two key enzymes of the Krebs cycle associated with a Warburg-type suppression of mitochondrial metabolism. We hypothesized that supplementation with L-glutamine (GLN), that can enter the Krebs cycle downstream this enzymatic bottleneck, would normalize vascular function and alleviate mitochondrial dysfunction. To test this hypothesis, mice with chronic L-NMMA-induced ECD were co-treated with GLN at different concentrations for 2 …
