AANS International Lifetime Recognition Award International Reception

INTRODUCTION, AWARDS AND LECTURES ABOUT AANS Founded in 1931 as the Harvey Cushing Society, the American Association of Neurological Surgeons (AANS) is a scientific and educational association with over 7,400 members worldwide. The AANS is dedicated to advancing the specialty of neurological surgery in order to provide the highest quality of neurosurgical care to the public. All Active members of the AANS are board certified by the American Board of Neurological Surgery, the Royal College of Physicians and Surgeons of Canada, or the Mexican Council of Neurological Surgery, A.C. Neurosurgery is the medical specialty concerned with the prevention, diagnosis, treatment and rehabilitation of disorders that affect the spinal column, spinal cord, brain, nervous system and peripheral nerves. For more information on what neurosurgeons do, visit our public pages at www.NeurosurgeryToday.org. James R. Bean, MD James R. Bean, MD, was named president of the American Association of Neurological Surgeons (AANS) at the 76th AANS Annual Meeting in Chicago, Ill., April 26-May1, 2008. An active member of the AANS since 1988, Dr. Bean served for three years as AANS treasurer prior to serving his term as president-elect. He served as editor of the AANS Bulletin (now AANS Neurosurgeon) from 2003-2005. He has served as chairman of the AANS/CNS Council of State Neurosurgical Societies (1997-1999), the AANS/CNS Coding and Reimbursement Committee (2000-2002), and the AANS/CNS Washington Committee (2002-2004). He is a member of the following committees: Executive, Finance, the Neurosurgery Research and Education Foundation (NREF) Executive Council, NeurosurgeryPAC Board of Directors, Nominating (Chair), and Strategic Planning. Dr. Bean completed his undergraduate work at the University of Virginia in 1970, and received his medical degree from the Tulane University School of Medicine in 1973. He www.AANS.org

completed his neurosurgical residency at the University of Kentucky Medical Center in 1980, and a research fellowship focusing on brain tumor immunology (1978) and cerebrovascular ischemia (1979) at the Institute of Neurology, National Hospital for Nervous Diseases, Gough Cooper Department of Neurological Surgery, Queen Square in London, England. Dr. Bean became Board-certified in 1983. Dr. Bean is currently president of Neurosurgical Associates, PSC, in Lexington, Ky., the practice he joined in 1982. He is a member of numerous professional societies including the American College of Surgeons, American Medical Association, Congress of Neurological Surgeons, Kentucky Medical Association, Kentucky Neurosurgical Society, Lexington Medical Society and the Southern Neurosurgical Society. Dr. Bean has published numerous journal articles and book chapters including Concepts in Neurosurgery, and was a previous editor (1994-2000) of Changing Times, a socioeconomic fax newsletter.

CUSHING CIGARETTE BOX Each year at the Annual Meeting of the American Association of Neurological Surgeons (AANS), the outgoing president is presented with a special momento of his year in office—the “Cushing Cigarette Box”— representing more than a half century of neurosurgical tradition. The sterling silver Cushing Cigarette Box was originally presented to Harvey Cushing, MD, by the surgical staff at Peter Bent Brigham Hospital on April 14, 1931, commemorating Dr. Cushing’s 2,000th verified intracranial tumor operation. Beginning with this cherished tradition back in 1959, Dr. Cushing’s nephew, E. H. Cushing, MD, presented the cigarette box to the AANS president and asked that it be passed on to each succeeding president as a symbol of the Association’s highest office.

2007 Research Fellow H. Francis Farhadi, MD, PhD NREF/DePuy Spine Research Fellow University of Texas Sponsor: Michael G. Fehlings, MD, PhD Project title: Transcriptional Programming of the Myelin Basic Protein Gene Following Spinal Cord Injury in the Mouse Following spinal cord injury (SCI), oligodendrocyte death leads to pronounced myelin sheath degradation which precludes rapid and efficient conduction. Demyelination combined with incomplete remyelination have become increasingly recognized as prominent components of secondary degeneration. To determine whether the chronic hypomyelination seen reflects a failure of surviving or newly-formed adult oligodendrocytes to recapitulate the robust developmental myelinogenesis program, I propose to undertake a comprehensive functional analysis of myelin basic protein gene regulation following experimentally-induced SCI. First, expression phenotypes of various transgenic lines bearing different combinations of regulatory sequences will be analyzed to determine which sequences are sufficient or required for re-expression during the incomplete remyelinative process. Then, a number of molecular assays will be employed to identify potential associated transcription factors and upstream interacting proteins. Candidate molecules will in turn be tested for their ability to enhance reporter gene expression Introduction, Awards and Lectures

Sponsor: Cynthia Whetmore, MD Project title: Modulation of Bmil Expression in Pediatric Medulloblastoma. The proper integration of extrinsic and intrinsic signals is critical for the proliferation and differentiation of neuronal precursors during normal cerebellar development and the corruption of these pathways are believed to contribute to the development of medulloblastoma. Bmi1, a member of the polycomb family of chromatin remodeling genes, has recently been shown to be involved in the proliferation of granule cell precursors during normal cerebellar development. Bmi1 is overexpressed in a subset of human medulloblastomas and recent studies suggest a link between Bmi1 and sonic hedgehog (Shh) pathway activation. The goal of the present proposal is to determine whether Bmi1 is necessary for Shh signal transduction and proliferation in normal and tumorderived stem cells and whether Bmi1 expression is part of the mechanism by which stem cells have increased radioresistance. We will elucidate the mechanism of Bmi1 in transduction of Shh signaling and determine if depletion of Bmi1 will inhibit tumor formation in a murine model of medulloblastoma. The overall goal of this research is to determine potential targets for the development of future therapy for childhood medulloblastoma.

2007 Research Fellow James Frazier, MD NREF/ Biomet Research Fellow Johns Hopkins University School of Medicine Sponsor: Alfredo Quinones-Hinojosa, MD Project title: Determination of the Role PDGF and EGF in the Migratory Pattern of Brain Cancer Stem Cells and Comparison of this Migratory Pattern to Normal Fetal and Adult Human Stem Cells in an In Vitro Assay and In Vivo Rodent Model using NOD/SCID/ IL2rynull Mice. The objective of this research is to study neural stem cells in the human brain and consequently the effect that PDGF and EGF have on the migratory behavior of these stem cells. We will test the hypothesis that human adult stem cells have the ability to migrate and that their manipulation with PDGF and EGF can change them to a more aggressive migratory behavior that resembles that of high-grade tumors and/or the fetal human utilizing both in vitro and in vivo studies. 2007 Research Fellow Jason L. Gerrard, MD, PhD Research Fellow Massachusetts General Hospital/Harvard Sponsor: Emad N. Eskandar, MD Project title: The role of the Primate Hippocampus and Basal Ganglia Circuits in Visual-Motor Associative Learning. The roles of the basal ganglia in movement planning and execution and the hippocampus in associational memory formation are well established. There is increasing evidence that the basal ganglia also play a critical role in associative motor learning. Moreover, there are a number of known connections between structures within the basal ganglia and the hippocampus. Adult Rhesus monkeys will be trained in a spatial-motor learning task. Single neuron recordings will be obtained, simultaneously, from the anterior striatum www.AANS.org

Tabar, MD Project title: Generation of Purified Motor Neurons from Human Embryonic Stem Cells for Cell Therapy in Amyotrophic Lateral Sclerosis. Amyotrophic Lateral Sclerosis (ALS) is a disorder characterized by motorneuron death. Human embryonic stem (hES) cells can be differentiated to motorneurons in vitro, however such preparations are contaminated by neural precursors that produce tumors in vivo. Our proposal involves a genetic modification of hES cells that will allow motorneuron purification for grafting into ALS mice. We propose to transfect hES cells with a bacterial artificial chromosome (BAC) containing the motorneuron-specific HB9 promoter driving expression of the green fluorescent protein, thereby fluorescently labeling motorneurons. Motorneurons will be purified with fluorescence-activated cell sorting and transplanted into the spinal cord of ALS mice. 2007 Research Fellow Uzma Samadani, MD, PhD ACS/AANS-NREF Faculty Career Development Award New York University Medical Center Sponsor: Howard L. Weiner, MD Project title: Sonic Hedgehog Therapy After Lysis of Intracerebral Hemmorhage. Intracranial hemorrhages result in high morbidity and mortality through several mechanisms including disruption of www.AANS.org

adjacent white matter tracts. Repair of these tracts may be possible through recruitment of neural progenitor cells induced to proliferate, differentiate and function by a myriad of signal transduction molecules. We compare the baseline endogenous subventricular zone stem cell division rate, with the rate seen after induced intracranial hemorrhage and pretreatment with the small molecule sonic hedgehog. The utilization of small molecule therapy to promote restoration of neurologic function after hemorrhage ultimately has implications for the treatment of deficits caused by other mechanisms including stroke and trauma.

MELK plays, we would provide avenues for potential modulation of neurogenesis dependent on MELK expression. Further, synthetic agonists of MELK could be used to modulate the amplification of neural progenitors for clinical application.

Project title: Optimization of N-acetylcysteine (NAC) Administration for Neuroprotection in an Experimental Rat CNS Injury Model and Investigations into the Pathophysiology of Posttraumatic Hydrocephalus (PTH).

Sponsor: Alexy Terskikh, PhD Project title: Role of MELK in Self-Renewal of Neural Progenitors. Stem/precursor cells hold great promise for cell replacement therapies and regenerative medicine, but their clinical success will depend on our ability to control their selfrenewal and differentiation. MELK is a gene that may modulate proliferation in neural precursors and is found in the subventricular zone of MELK-EGFP promoter-reporter transgenic mice. We intend to investigate the molecular mechanisms that regulate neural stem cell proliferation and self-renewal. To do this we will evaluate the proliferative capacity and cell fate of MELK/EGFP-positive cells isolated from our transgenic animals via transplantation assays and determine if these cells from the neonatal pup subventricular zone are proliferating neural precursors in vivo. Subsequently these cells will be evaluated in vitro with siRNA and cDNAs for assessment of proliferative capacity at variable levels of MELK gene product, as well as investigate the involvement of putative MELK targets and their effects on proliferation and self-renewal. By understanding self-renewal and the role

Traumatic brain injury (TBI) remains a major source of morbidity and mortality with 1.5 million sustaining TBI each year; of these, 80-90,000 experience long-term disability (CDC 2001). There are currently no effective pharmacological agents used in clinical practice that reduce secondary brain injury. Additionally, hydrocephalus occurs in 20% of these patients and is associated with poor outcome (Marmarou 1996). The mechanism for posttraumatic hydrocephalus formation is incompletely understood, but likely involves fibrosis of the pathways of cerebrospinal fluid (CSF) absorption: cervical lymphatics and arachnoid granulations. Fibrosis following TBI may be due to induction of connective tissue growth factor (CTGF) which is, in turn, regulated by reactive oxygen species (ROS). One of the physiological defense mechanisms against oxidative stress involves removal of free radicals by the tripeptide glutathione (GSH), formed by three amino acids: glutamate, glycine, and cysteine. N-acetylcysteine (NAC), a thiol containing molecule, has both direct anti-oxidant activity and serves as a precursor for GSH biosynthesis. The following experimental design is intended to optimize administration of NAC for neuroprotection in an experimental rat TBI model, provide novel insight into the mechanism and prevention of posttraumatic hydrocephalus, and, if successful, will lead directly to clinical trials of NAC in human TBI.

Given that breast and prostate cancer account for the majority of spinal metastases, and that BMPs 2 and 7 are currently used in spinal fusion operations, we propose to study the relationship of these growth factors to human tumor cell lines in a previously established rat spine tumor model. Specifically, MDA-231 human breast cancer cells will be implanted into the vertebral body of nude rats. Tumor size in the presence of local and systemically delivered BMPs will be evaluated via radiographs, motor strength testing, and histopathological assessment, and overall survival and onset to paresis will be measured. 2008 Research Fellow Suzanne Tharin, MD NREF/Porex Surgical Research Fellow Children’s and Brigham and Women’s Hospital, Harvard Medical School Sponsor: Jeffrey D.

Corticospinal motor neurons (CSMN) are the brain component of the 2-neuron circuitry (along with spinal motor neurons) controlling the most precise voluntary movement. Understanding their development could contribute to future therapies for spinal cord injury. The goal of my research is to investigate CSMN axon targeting to cervical vs. lumbar spinal cord.

immature, cervical- and lumbar- projecting murine CSMN using retrograde labeling and fluorescence activated cell sorting (FACS), and investigate their axon targeting choices in coculture with spinal cord explants and with set of potential control molecules identified in Dr. Macklis’ lab. 2008 Young Clinician Investigator Award John Kuo, MD Young Clinician Investigator Awardee University of Wisconsin – Madison Sponsor: Robert J. Dempsey, MD Project title: Identifying Molecules that Regulate the Blood-Brain Barrier using Stem Cells. Endothelial cells in the brain form a unique blood-brain barrier (BBB) that prevents entry of many molecules. It was recently shown that the neural stem cells (NSC) induce BBB formation, whereas we hypothesize that peri-vascular GBM stem cells (GBM SC) contribute to observed tumor BBB disruption since they secrete the angiogenic vascular endothelial growth factor (VEGF). This project proposes to identify molecular regulators of endothelial function by analyzing NSC and GBM SC interactions with BBB. Candidate BBB formation molecules will be identified through testing with NSC, and candidate BBB disruption molecules identified via testing with GBM SC in an in vitro stem cell/BBB co-culture system. Differential BBB integrity will be assayed via changes in transendothelial resistance (TEER) and molecule markers. Preliminary data show GBM SCconditioned media significantly reduce TEER and cause BBB disruption. Soluble factors will be identified via cytokine/angiogenesis arrays and mass spectrometry approaches, verified for expression and tested for BBB function with specific inhibitors. Vascular endothelial growth factor (VEGF) will be tested and specifically inhibited with anti-VEGF antibody to determine its contribution to BBB disruption. This paradigm is applicable to testing other candidate BBB regulators. Identified regulatory molecules may potentially restore the BBB in diseases such

as stroke and head trauma, or regulate BBB permeablility for optimizing delivery of pharmacologic, gene or stem cell therapies. 2008 Young Clinician Investigator Award Aaron Dumont, MD Young Clinician Investigator Awardee University of Virginia Sponsor: Gary K. Owens, PhD Project title: Inflammatory Cytokines and Smooth Muscle Cell Phenotypic Modulation in Cerebrovascular Disease. Cerebral aneurysms are common in the general population and aneurysm rupture remains a catastrophic event for which outcomes remain poor. Despite this, our understanding of the basic biology of aneurysms is limited. Understanding basic aneurysm biology will be critical to development of future treatments for patients harboring cerebral aneurysms. There is mounting evidence to suggest that inflammatory cytokines may specifically be important in the formation and progression of cerebral aneurysms. The present proposal attempts to elucidate the molecular mechanisms by which cytokines may directly evoke changes in cerebral vascular smooth muscle cells (SMCs) producing an inflammatory phenotype in vitro, and also attempts to determine a potential direct role for inflammatory cytokines and SMC phenotype modulation in the development and progression of cerebral aneurysms in vivo. 2008 Young Clinician Investigator Award Jonathan Miller, MD NREF/Biomet Microfixation Young Clinician Investigator Awardee Case Western Reserve University Sponsor: Warren Selman, MD Project title: Electrophysiological Alterations Following Minimal Traumatic Brain Injury. The goal of this project is to develop a better

15 understanding of the electrophysiological changes that occur after mild traumatic brain injury (mTBI). We plan to use a closed head injury model in rats to test the hypothesis that the functional deficits after mTBI: (1) are associated with characteristic electrophysiological changes in specific areas of the brain; (2) may be identified using noninvasive methods such as EEG; and (3) may be reversed to some degree by means of high-frequency field stimulation using a stereotactically implanted electrode. This information should assist in the design of novel strategies for diagnosis and treatment. William P. Van Wagenen Fellowship The William P.

NEUROSURGERYPAC Federal policymakers have a huge impact on how neurosurgeons practice, when we practice, what we get paid and what patients we see; this influence is only growing stronger. In order to maximize effective advocacy efforts on behalf of neurosurgery, the AANS has yet another tool in its advocacy arsenal: a political action committee called NeurosurgeryPAC. Its mission is to support candidates for federal office who support neurosurgeons. NeurosurgeryPAC does this by making direct campaign contributions to candidates for the US Senate and the US House of Representatives who are supportive of the issues important to neurosurgery. NeurosurgeryPAC is nonpartisan and does not base its decisions on party affiliation, but instead focuses on the voting records and campaign pledges of the candidates. Stop by the NeurosurgeryPAC booth in the

registration area to learn about current campaigns, recent successes and how you can help. AANS members who are citizens of the United States and who pay dues or have voting privileges can make contributions at this booth, or in the AANS Resource Center.

NEUROSURGERY RESEARCH AND EDUCATION FOUNDATION (NREF) Advancing Neurosurgery Through Research Since 1981, the NREF has continued to ensure the viability and expansion of the field of neurological surgery, based on fundamental research in the basic sciences and clinical enterprises pertinent to neurosurgery. Through support from the neurosurgical community, the NREF has stimulated learning by neurosurgeons and enhanced educational opportunities throughout their careers. Over the past 28 years, the Foundation has established two grant programs to fulfill this need. The Research Fellowship provides research training for neurosurgeons who are preparing to dedicate their futures to the research and application of new scientific knowledge. The Research Fellowship is a two-year grant for $70,000 or a one-year grant of $40,000. The one year Young Clinician Investigator Award (YCI) is a $40,000 grant, which provides young faculty members funding for pilot studies, which enables them to develop preliminary data to support applications for more permanent funding. Have you supported the NREF yet this year? Now you can make your contribution to the Foundation at the AANS Resource Center, Booth #1135. This year, the NREF will have someone available to take donations, provide updated information about programs and answer any questions.

015 Negotiating with Hospitals: Challenging the Experts Room 24A, San Diego Convention Center

www.AANS.org

SUNDAY, MAY 3 MD; M. Sean Grady, MD; Gregory B. Lanford, MD Providing optimal patient care requires neurosurgeons to be available and accessible within the current health care environment. This course will provide case studies of both success and failures from neurosurgeons that negotiated with hospitals. Building on the didactic information presented in previous years, the course will allow participants to gain important insight into how and why strategies succeeded or failed for these experienced neurosurgeons. Each case study evaluates approaches to ensure a neurosurgical career satisfaction, financial stability, expansion of practice opportunities and availability for patient care. Special attention is paid to the interwoven financial relationships between hospitals and neurosurgeons and how best to leverage a neurosurgeon’s value to his/her hospital in negotiating resources. All course participants will be requested to submit their own hospital negotiation case studies for didactic discussion during the second part of the highly interactive and results oriented portion of the course. Clinic Fee: $450 Learning Objectives: After completing this educational activity, participants should be able to: • Assess the direct and indirect financial contribution neurosurgeons make to a hospital and explain administrative “financial-speak” essential to successful negotiations • Define alternative revenue sources for neurosurgeons in your hospital and community • Determine practical approaches for solving current dilemmas in neurosurgeon-hospital relationships • Discuss how to design the business case to bring a new program to your hospital

This course is a new format to help diffuse information about Minimal Access surgery through case-based, interactive, and didactic teaching. This completely case-based approach is designed to engage and help the participants explain the thought process that helps determine the faculty’s surgical decision making. The cases increase in complexity and scope, altering the scenarios until all come to explain the factors which influence our own surgical practice. As the cases become increasingly complex, the faculty and audience alike are forced to address the difficult, sometimes impossible choices encountered. The goal is for every surgeon who participates to explain the thought process behind how different surgeons, when presented with a surgical dilemma, choose to address a case. Be prepared to participate in helping form a treatment algorithm as to how to address various surgical issues, while focusing on minimally invasive spine surgery and the variety of patients who increasingly desire this form of treatment.

This hands-on clinic uses cadaver dissection to review clinically relevant anatomy and surgical approaches to the brachial plexus and upper extremity nerves.

Clinic Fee: $450

CONTINUING MEDICAL EDUCATION (CME) ANNUAL MEETING MISSION

CME CREDIT FOR POSTERS

The main goals of the American Association of Neurological Surgeons’ Annual Meeting are to serve as a primary source of continuing medical education, tailored specifically to our specialty; to advance neuroscience research; and to promote a climate conducive to excellence in clinical practice. The Annual Meeting Committee is dedicated to meeting these goals. The AANS Annual Meeting is the principal mechanism for the transfer of scientific, technical, and intellectual information to the neurosurgical community.

Physicians may claim AMA PRA Category 1 Credits™ directly from the AMA for preparing a poster presentation, which is also included in the published abstracts. To obtain credit from the AMA for this, physicians can either claim them on their AMA PRA certificate application or apply directly to the AMA for an AMA PRA Category 1 Credits™ certificate. Physicians may claim AMA PRA Category 2 Credit™ for viewing scientific posters. Physicians should self-claim credit to the AMA on their AMA PRA certificate application form.

Feedback obtained from attendee evaluation forms is one important factor in determining the program content of this meeting. Special recognition is extended to the individuals of the 2009 Annual Meeting Committee and the committees they represent for their perseverance and commitment to making the Annual Meeting of the American Association of Neurological Surgeons a success.

CONTINUING MEDICAL EDUCATION (CME) The AANS is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians. The AANS designates this educational activity for a maximum of 43.25* AMA PRA Category 1 Credits™. Physicians should only claim credit commensurate with the extent of their participation in the activity. *A maximum of 18 AMA PRA Category 1 Credits™ for general sessions only.

CME CREDIT FOR BREAKFAST SEMINARS Attendees will receive a maximum of two AMA PRA Category 1 Credits™ for each breakfast seminar they attend. Physicians should only claim credit commensurate with the extent of their participation in the activity.

CME CREDIT FOR PRACTICAL CLINICS Attendees will receive a maximum of 4 AMA PRA Category 1 Credits™ for all eligible halfday clinics and 8 AMA PRA Category 1 Credits™ for all eligible full day clinics. Physicians should only claim credit commensurate with the extent of their participation in the activity. www.AANS.org

CONTINUING EDUCATION FOR ALLIED HEALTH PROFESSIONALS Practical Clinics, Breakfast Seminars and afternoon sessions designated with an “N&PE” are designed with Allied Health professionals in mind. Nursing contact hours have been applied for the specified breakfast seminars and practical clinics designed for nurses. Specific hours are subject to approval. An application for approval of nursing contact hours has been submitted to the Illinois Nurses Association Approver Unit. Please call the AANS for more information about the contact hours. Physician assistants will receive a certificate of attendance after the completion of the meeting which can be submitted to the American Academy of Physician Assistants for acceptance towards the Physician Assistant Category I (preapproved) CME requirement.

CLAIM CME CREDIT THE EASY WAY Again this year, Annual Meeting attendees will self-report CME credit for the programs they attend by going online to MyAANS.org from any computer with internet service. Please have your MyAANS.org user name [email address] and password handy during and after the meeting for convenient completion and submission. Self reported CME will not be credited if the individual does not pick up his/her registration packet. Do not self-report CME credit for optional ticketed events such as breakfast seminars and practical clinics. By turning in your tickets on site, credit will automatically be added to your record in MyAANS.org. Please contact the AANS if you are not in attendance for the full breakfast seminar or

135

practical clinic so that your credit can be adjusted accordingly.

DISCLOSURES ACCME’s Updated Standards for Commercial Support require that anyone in a position to control the content of the education activity has disclosed all financial relationships with any commercial interest. Failure or refusal to disclose or the inability to satisfactorily resolve the identified conflict may result in the withdrawal of the invitation to participate in any AANS education activities. The ACCME defines a “commercial interest” as any entity producing marketing, re-selling, or distributing healthcare goods or services consumed by, or used on, patients. Disclosures will be published in the Annual Meeting Program Guide and Scientific Program CD, which will be distributed to all registrants at the meeting. Disclosures will also be published online and on DVD for the AANS Annual Meeting Archived Presentations.

DISCLAIMER The material presented at the 77th Annual Meeting has been made available by AANS for educational purposes only. The material is not intended to represent the only, nor necessarily the best, method or procedure appropriate for the medical situations discussed, but rather it is intended to present an approach, view, statement, or opinion of the faculty, which may be helpful to others who face similar situations. Neither the content (whether written or oral) of any course, seminar or other presentation in the program, nor the use of a specific product in conjunction therewith, nor the exhibition of any materials by any parties coincident with the program should be construed as indicating endorsement or approval of the views presented, the products used, or the material exhibited by the AANS, or by its committees, commissions or affiliates. The AANS disclaims any and all liability for injury or damages to any individual attending the Annual Meeting, and for all claims which may arise out of the use of the techniques demonstrated therein by such individuals, whether these claims shall be asserted by physicians or any other person. There may be, on occasion, changes in faculty and program content. Continuing Medical Education (CME)

In accordance with the Standards for Commercial Support established by the Accreditation Council for Continuing Medical Education (ACCME), speakers, paper presenters/authors and staff (and the significant others of those mentioned) are

Continuing Medical Education (CME)

asked to disclose any relationship* they or their co-authors have with commercial interests which may be related to the content of their lecture. The ACCME defines “relevant financial relationships” as financial relationships in any amount occurring within the past 12 months that create a conflict of interest. Speakers, paper presenters/authors and staff (and the significant others of those mentioned) who have disclosed a relationship* with

commercial interests whose products may have a relevance to their presentation are listed below. *Relationship refers to receipt of royalties, consultantship, funding by research grant, receiving honoraria for educational services elsewhere, or any other relationship to a commercial interest that provides sufficient reason for disclosure.
