Houston Methodist Sugar Land Hospital Implements New Diagnostic Procedures
H
ouston Methodist Sugar Land Hospital recently expanded its diagnostic repertoire to include endobronchial (EBUS) and endoscopic (EUS) ultrasound testing. Performed in a dedicated endoscopy suite, the two procedures are noninvasive alternatives to major surgeries and are used to diagnose and stage cancer and detect infections. Both procedures are performed by a multidisciplinary team that includes a pulmonologist (EBUS) or gastroenterologist (EUS), an anesthesiologist, pathologist, and endoscopy staff. The premise of the EBUS procedure is to collect lung or thoracic lymph node biopsies through a transbronchial needle aspiration guided by an ultrasound probe to allow visualization of internal
structures. Similarly, the EUS procedure obtains biopsies from tissues surrounding the gastrointestinal tract. After the specimens are obtained and while the patient is still sedated, they are rapidly and thoroughly examined by the pathologist to ensure specimen quality and determine types of cells present. “EBUS is a rapid process that provides a reliable and noninvasive alternative to performing openchest surgery to gain access to thoracic lymph nodes,” explained Dr. Seema Mullick, Medical Director of Laboratory Services at Houston Methodist Sugar Land Hospital. “We are extremely proud to be the only community hospital in the Fort Bend area to offer these highly sophisticated procedures to our patients,” she stated.
Both EBUS and EUS were implemented in early 2014. Currently, there are four pulmonologists and one gastroenterologist performing these procedures. However, Dr. Mullick estimates that as the hospital continues to expand, the service volume will increase.

New Tests Available from Houston Methodist Diagnostic Laboratory: Gastrointestinal Pathogen Assay
T
he Microbiology Laboratory of the Houston Methodist Hospital recently validated and implemented a real-time PCR assay to detect the 22 most common gastrointestinal pathogens that cause diarrhea, including Adenovirus (type 40 and 41), Astrovirus, Campylobacter species, Clostridium difficile (Toxin A/B), Cryptosporidium species, Cyclospora cayetanensis, Entamoeba histolytica, Escherichia coli O157, Enteroaggregative E. coli, Enteropathogenic E. coli, Enterotoxigenic E. coli, Shiga-like Image from www.filmarray.com toxin-producing E. coli, Shigella/Enteroinvasive E. coli, Giardia lamblia, Norovirus, Plesiomonas shigelloides, Rotavirus, Salmonella species, Sapovirus, Vibrio cholerae, and Yersinia enterocolitica. Diarrhea, which is commonly caused by an infection of the gastrointestinal tract by one or more pathogens, is a significant source of morbidity and mortality worldwide. In the United States, approximately 375 million episodes of diarrhea are estimated to occur annually. Children, the elderly, and immunocompromised individuals are particularly susceptible to severe disease. Real-time PCR is a highly sensitive and specific method to detect the presence of nucleic acid from pathogens in a clinical specimen. The new Gastrointestinal Pathogen Assay can rapidly detect organisms that are difficult to identify using traditional culture-based methods. The assay is FDA-approved and has a 4-hour turnaround time after receipt in the laboratory. For more information on the Gastrointestinal Pathogen Assay or any Microbiology Laboratory test, please contact: Dr. James Davis: jrdavis@houstonmethodist.org, Dr. Randall Olsen: rjolsen@houstonmethodist.org, or Ms. Patricia Cernoch: pcernoch@houstonmethodist.org

Dr. Youli Zu Awarded Two Grants to Improve Cancer Cell Detection
D
r. Youli Zu was recently awarded a 3-year grant from the Cancer Prevention and Research Institute of Texas (CPRIT) for his application titled “Accurate and high-throughput detection of breast and ovarian cancer cells in whole blood”. His proposal aims to develop a one-step, aptamer-based assay that will identify circulating tumor cells (CTCs) in cancer patient blood. Dissemination of cancer cells from the primary tumor to distant tissues and organs is the major cause of cancer-related deaths. Over the past decade, many clinical studies have shown that CTCs present in the bloodstream are associated with disease progression, recurrence, and ultimately patient survival. However, it has been a challenge to develop methods to accurately identify and enumerate CTCs due to their scarcity. To date, the only FDA-approved technology relies on a complicated, multi-step process that can lead to loss and damage of already very rare cells and takes over 20 hours to complete.
Dr. Youli Zu
To address this important clinical issue, Dr. Zu and his team plan to develop a revolutionary single-step platform that will allow for rapid identification of CTCs. This new assay will be based on aptamer technology, an area of active research in Dr. Zu’s laboratory. Aptamers are short DNA or RNA sequences that function similarly to antibodies and preferentially bind their target proteins on the surface of cancer cells. Once the CTC detection technology is developed, the one-step assay will offer a system for accurate detection of CTCs without a lengthy isolation protocol. In addition to the CPRIT award, Dr. Zu and his partners at Telovision, LLC, have received a grant from the Small Business Technology Transfer Program at the National Institutes of Health. The grant, titled “A simple assay system for rapid detection of circulating tumor cells”, will provide funds to commercialize this technology. Dr. Zu is Medical Director of Hematopathology and Director of the Cancer Pathology Laboratory in the Department of Pathology and Genomic Medicine. He is also Professor of Pathology and Laboratory Medicine at Weill Cornell Medical College of Cornell University. For more information on Dr. Zu and his research, please visit www.houstonmethodist.org/youlizumdphd

Dr. Adriana Rosato Awarded a Grant to Study Methicillin-Resistant Staphylococcus aureus Infections
D
r. Adriana Rosato received a grant from the National Institute of Allergy and Infectious Diseases for her application titled “Molecular bases of DAP-resistance-mediated sensitization to beta-lactams in MRSA”. This study will evaluate molecular mechanisms associated with daptomycin (DAP) resistance in methicillin-resistant Staphylococcus aureus (MRSA) infections. MRSA infections pose a significant health risk because they occur both in the community and in healthcare settings, where they can induce infections of surgical sites, bacteremia, and form biofilms. Importantly, MRSA infections are difficult to treat because these bacteria are resistant to a vast majority of antibiotics. DAP is a relatively new antibiotic that was FDA-approved in 2003 for treatment of systemic and life-threatening infections caused by Gram-positive bacteria, including MRSA. However, DAP-resistant MRSA strains have been recently identified.
Dr. Adriana Rosato
Prior studies in Dr. Rosato’s laboratory identified several mechanisms of DAP resistance in previously-sensitive MRSA strains. Importantly, they also showed that these DAP-resistant bacteria become sensitive to oxacillin, a betalactam class of antibiotics, although the mechanism of this sensitization had not been identified. Studies proposed in this application will evaluate the molecular mechanisms underlying DAP resistance and oxacillin re-sensitization. Dr. Rosato is a research scientist in the Department of Pathology and Genomic Medicine at Houston Methodist Hospital and Associate Member of the Houston Methodist Research Institute. Prior to joining the Department in 2010, Dr. Rosato was Assistant Professor in the Department of Internal Medicine at Virginia Commonwealth University.

Dr. David Morens Presents a Special Seminar on Emerging Infectious Threats
T
“It is critically important to develop novel diagnostics to identify biomarkers of incubating infections. Until then, disease containment is our best strategy to curb further infection spread.” - Dr. David Morens
he Department of Pathology and Genomic Medicine hosted a special seminar presented by Dr. David Morens, Senior Adviser to the Director of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health on September 22, 2014. Dr. Morens’ talk, titled “Chikungunya, Ebola, and Other Emerging Threats: Emergence and Pathogenesis”, provided an overview of several types of hemorrhagic fevers that pose a significant health threat to the world, with special emphasis on the current Ebola epidemic ravishing West Africa. Viral hemorrhagic fevers are caused by viruses that belong to four distinct families. Of these, dengue virus is the most common cause of infection and death in tropical and subtropical regions of the world. Dr. Morens noted that up to 1/3 of the world’s population is at risk of contracting dengue fever. This is especially important as international travel leads to wider dissemination of previously contained, geographically-localized infectious diseases. Dr. Morens also discussed the ongoing Ebola
epidemic. While previous Ebola outbreaks occurred in rural regions of Africa, most current cases have been diagnosed in urban, highly-populated areas. Since Ebola is transmitted through contact with the infected individual’s body fluids, the population density in the affected regions has contributed to the spread of the disease. Dr. Morens noted that until vaccines and better treatment strategies are developed, disease containment is the best strategy to curb further spread. Finally, he concluded that novel diagnostics, capable of detecting diseases during their incubation periods, are urgently needed. Three days after presenting at Methodist, Dr. Morens was detailed to West Africa to assist with the response to the Ebola outbreak. Prior to accepting his current position at the National Institutes of Health, Dr. Morens was Professor of Tropical Medicine at the John A. Burns School of Medicine and Chairman of the Epidemiology Department at the School of Public Health at the University of Hawaii.
Special Seminar Announcement: “Epidemic Ebola Disease in West Africa, 2014: Personal Experience and Observations”
T
he seminar will be presented by George Risi, M.D., M.Sc., on Friday, October 31st, and will be held at 2:00 p.m. in the John F. Bookout Auditorium in the Houston Methodist Research Institute (HMRI R2-306). Dr. Risi is the infectious disease adviser and Director of the Regional Referral Hospital and Patient Isolation Facility at the St. Patrick Hospital in Missoula, Montana. The facility was built about 10 years ago to supplement the biosafety level 4 laboratory at Rocky Mountain Laboratories, part of the National Institute of Allergy and Infectious Diseases. Dr. Risi recently returned from spending four weeks with the World Health Organization in Sierra Leone caring for Ebola patients. He then spent time in Havana, Cuba, training about 165 health care workers who were traveling to West Africa to help with the Ebola epidemic.

Methodist Hospitals Host Breast Cancer Awareness Events
O
ctober is breast cancer awareness month. Women in the United States have about a 12% lifetime risk of developing breast cancer, which is highly treatable when diagnosed in the early stages. To improve early diagnosis, several Houston Methodist Hospitals hosted annual breast cancer awareness events. Houston Methodist Willowbrook Hospital hosted its second annual “Paint the Night Pink” on Wednesday, October 1, 2014. This free event featured live music, dinner, chair massages, onsite mammograms, and physician consultations. Additionally, a panel of experts discussed a variety of breast cancer-related topics, ranging from treatment strategies to procedures offered by the hospital, including innovative, padded mammogram machines. Houston Methodist Sugar Land Hospital partnered with the Sugar Land Town Square for the 5th Annual “Catwalk on City Walk” fashion show. The event was held on Wednesday,
October 8, 2014, and showcased the fashion of several local boutiques. All proceeds from this fun annual event went to the Houston Methodist Sugar Land Hospital Pretty in Pink Cancer Fund, which assists local cancer patients with various non-hospital costs. Additionally, during the month of October, Veritas Steak and Seafood restaurant in Town Square is offering a unique Pretty in Pink menu, with a portion of the sales also donated to the Pretty in Pink Cancer Fund. Houston Methodist West Hospital hosted its annual “Positively Pink” event on Saturday, October 18, 2014. This free, familyfun event aimed to raise breast cancer awareness and promote disease prevention. Positively Pink featured live music, food, children’s activities, and shopping booths.
