MedicalResearch.com Interview with: Kristen A. Ban, MD Loyola University American College Surgery Clinical Scholar MedicalResearch.com: What is the background for this study? What are the main findings? Response: The American College of Surgeons previously released surgical site infections (SSI) guidelines, and we wanted to update them with the most recent literature to give surgeons a concise, comprehensive document of recommended practices to reduce SSI. We were very fortunate to partner with our colleagues and content experts at the Surgical Infection Society for this update. There are a few areas where we had additional literature to support new or different guidelines. Blood glucose control is now recommended for all patients regardless of diabetic status. SSI reduction bundles have become very popular, and we emphasize that compliance must be high with all parts of these bundles to obtain the maximum benefit. Finally, we recommend cessation of prophylactic antibiotics at incision closure with some exceptions (mainly in regard to implanted material/hardware). (more…)

MedicalResearch.com Interview with: Adam Sachs MD Assistant Professor of Anesthesiology University of Connecticut School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: When women undergo appendectomy or cholecystectomy during pregnancy they are obviously concerned about the well being of their fetus. Unfortunately, the majority of the data available to council pregnant women is outdated and medical practice has significantly changed since their publication. (more…)

MedicalResearch.com Interview with: Vitor Mendes Pereira MD MSc Division of Neuroradiology - Joint Department of Medical Imaging Division of Neurosurgery - Department of Surgery Toronto Western Hospital - University Health Network Associate Professor of Radiology and Surgery University of Toronto  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study is a pooled analysis of two large prospective stroke studies that evaluated the effectiveness of mechanical thrombectomy (MT) using one of the stent retrievers (Solitaire device ) in patients with acute ischemic stroke related to large vessel occlusion(LVO). It is known (after 5 randomized controlled trials in 2015) that IV rtPA alone failed to demonstrated benefit when compared to MT associated or not to rtPA. A question is still open: what it is the real benefit of IV rtPA in the context of LVO, particularly in centres that can offer mechanical thrombectomy within 60 minutes after qualifying imaging?

MedicalResearch.com Interview with: Alex Carignan, MD, MSc Department of Microbiology and Infectious Diseases Université de Sherbrooke, Quebec, Canada  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Although reports of iatrogenic transmission directly linked to surgical power tools (SPTs) are rare, the decontamination of such instruments is challenging due to their complex designs, which may restrict access to cleaning and sterilization agents, and because they often become contaminated after use. Most studies on infection risk with ultrasonic surgical power tools include patients who underwent phacoemulsification surgeries,but it is logical to assume that lumen contaminants, including bacteria and proteinaceous material from previous operations, may be found in neurosurgery SPTs as well. During June 2015, the infection control department at our institution was notified of an increase in the number of surgical site infection cases following craniotomy since January 2015. We investigated an outbreak of neurosurgical SSIs at a tertiary care hospital in Quebec, Canada, to identify the outbreak’s cause, and our investigation strongly suggests that modifying the reprocessing procedure of an ultrasonic surgical aspirator caused the outbreak.

MedicalResearch.com Interview with: Deepak L. Bhatt, MD, MPH, FACC, FAHA, FSCAI, FESC Executive Director of Interventional Cardiovascular Programs, Brigham and Women’s Hospital Heart & Vascular Center Professor of Medicine, Harvard Medical School Boston, MA 02115 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cangrelor is a potent, fast on, fast off, intravenous ADP receptor antagonist that is now available for use during PCI. Glycoprotein IIb/IIIa inhibitors are intravenous antiplatelet agents that work by a different mechanism. Doctors have asked whether there is any advantage to combining them or whether one class is preferable to the other during PCI. We analyzed close to 25,000 patients from the CHAMPION trials. Cangrelor’s efficacy in reducing peri-procedural ischemic complications in patients undergoing PCI was present irrespective of glycoprotein IIb/IIIa inhibitor administration. However, glycoprotein IIb/IIIa inhibitor use resulted in substantially higher bleeding rates, regardless of whether the patient was randomized to cangrelor or to clopidogrel. Thus, in general, cangrelor and glycoprotein IIb/IIIa inhibitors should not routinely be combined. If an operator wishes to use a potent intravenous antiplatelet during PCI, cangrelor is similarly efficacious as glycoprotein IIb/IIIa inhibitors, but with less bleeding risk. (more…)

MedicalResearch.com Interview with: Dr Thomas H. Inge MD University of Colorado Denver School of Medicine Aurora, CO 80045 MedicalResearch.com: What is the background for this study? Response: Gastric bypass surgery helps severely obese teenagers lose weight and keep it off, according to the first long term follow up studies of teenagers who had undergone the procedure 5-12 years earlier. However, the studies show some patients will need further surgery to deal with complications or may develop vitamin deficiencies later in life, according to two studies published in The Lancet Diabetes & Endocrinology. Severe obesity is classified as having a BMI of 40 or over (around 100 pounds overweight) and affects around 4.6 million children and teenagers in the USA. It causes ill health, poor quality of life and cuts life expectancy. The studies are the first to look at long-term effects of gastric bypass surgery in teenagers. Until now, it has been unclear how successful the surgery is in the long-term and whether it can lead to complications. Thousands of teenagers are offered surgical treatment each year. (more…)

MedicalResearch.com Interview with: Jianmeng Liu, PhD, MD Professor in Epidemiology and Biostatistics Director, Institute of Reproductive and Child Health/key Laboratory of Reproductive Health Ministry of Health Director, Office for National Maternal and Child Health Statistics of China Peking University Health Science Center Beijing, China MedicalResearch.com: What is the background for this study? Response: Cesarean overuse can jeopardize maternal and child health. It has been widely concerned that cesarean rate in China is at an extremely high level. Concerns about “alarming” rates increased after a World Health Organization (WHO) report that 46.2% of births were delivered by cesarean in 2007-2008, based on analysis of deliveries in 21 hospitals of 3 provinces of China. Since 2002, reducing the cesarean rate has been a national priority, and a variety of policies, programs and activities have emerged at both the central and local governments. Previous national estimates of cesarean rates have been based on surveys with limited geographical coverage. Given the marked diversity of geography, economy, and life circumstances throughout China, survey estimates are likely to be sensitive to the area sampled. By analyzing county-level national data on cesarean rates that have been collected since 2008, this study aimed to determine the overall rate and change in rate of cesarean deliveries, examine geographic variation, and, in areas where declines occurred, assess changes in maternal and perinatal mortality.

MedicalResearch.com Interview with: Dr Torsten Olbers PhD Department of Gastrosurgical Research Institute of Clinical Sciences University of Gothenburg, Sahlgrenska University Hospital Gothenburg Sweden  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background to study was the lack of effective treatments for adolescents with severe obesity and the observation that many adults undergoing gastric bypass regret that they didn't´t do it earlier. The medical indication is to hopefully prevent development of diseases and organ damage due to cardiovascular risk factors and to enable them to have normalised psychosocial development (education, relation etc). In fact most of the adolescents undergoing surgery had parents having undergone surgery. (more…)
Author Interviews, Lancet, OBGYNE, Surgical Research / 22.12.2016

MedicalResearch.com Interview with: Dr Rachael Wood PhD Consultant in Public Health Medicine - women and children's health NHS National Services Scotland Information Services Division Edinburgh MedicalResearch.com: What is the background for this study? Response: Mesh surgery for female stress urinary incontinence and pelvic organ prolapse is currently controversial. Mesh surgery was introduced to overcome recognised limitations of traditional, non-mesh, surgery for these conditions, in particular extensive surgery and long hospital stays for incontinence and high failure/recurrence rates for prolapse. Mesh surgery may therefore offer additional benefits over traditional surgery. Mesh surgery may also carry additional risks however, with patient advocacy groups highlighting cases of severe, long term, mesh-related complications in some women who have undergone mesh surgery. We therefore used routinely available, population based hospital discharge records from Scotland to identify women having mesh and non-mesh procedures for incontinence and prolapse. We then followed the women up for up to 5 years to assess how often they were readmitted for complications or further incontinence or prolapse surgery. (more…)

MedicalResearch.com Interview with: Prof. Cathryn Glazener PhD Health Services Research Unit University of Aberdeen Aberdeen,UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prolapse is a condition that affects up to half of all women after childbirth. Women notice a bulge or discomfort in their vaginas due to pressure from the bladder, bowel or womb moving downwards. Women who have surgery for their prolapse have a 3 in 10 chance of needing at least one more operation, so the success rate is not great. Gynaecologists hoped that by reinforcing their repairs the success rate would get better. PROSPECT was a pragmatic, multicentre randomised controlled trial conducted in 35 centres across the UK. Women undergoing their first operation for prolapse were randomised to having a standard repair of the front or back wall of the vagina, or a repair reinforced by synthetic non-absorbable mesh, or a biological graft. We found that, in contrast to previous research, women were just as likely to be cured after standard surgery rather than reinforced repairs. They were just as likely to have other symptoms such as bladder or sexual problems, and other adverse effects such as infection, bleeding or pain. However, about 1 in 10 of the women who had mesh did have mesh exposure when a small portion of the mesh becomes visible through the vaginal wall. Although many women did not have symptoms, about half of those women needed a small operation to remove or bury the exposed mesh. (more…)

MedicalResearch.com Interview with: Frederick L. Grover, M. D. Professor, Division of Cardiothoracic Surgery Past Chair, Department of Surgery University of Colorado School of Medicine-Anschutz Medical Campus Aurora, CO Past President, Society of Thoracic Surgeons Vice Chair, Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry MedicalResearch.com: What is the background for this study? What are the main findings? Response: Following approval of the first transcatheter aortic heart valve late in 2011 the TVT-R was established and data entry was mandated by CMS for all patients who were undergoing transcatheter valve therapy.  Data is currently collected on transcatheter aortic valves (TAVR) from two companies, transcatheter mitral clip procedures (TMC), transcatheter mitral valve in valve or valve in ring procedures and aortic valve in valve procedures.  A report is published annually jointly in the Journal of the American College of Cardiology (JACC) and the Annals of Thoracic Surgery (ATS).  This report contains data from the beginning of 2012 through December 31, 2015.  Peoperative risk factors, operative details and outcomes data are collected prior to procedures, during the hospitalization, 30 days post procedure and at one year and later data can be collected by linking to CMS administrative data. For this annual report we concentrated on touching on some of the highlights since the length of the manuscript is limited. We discussed the trends in TAVR, since this is the most common procedure performed, the last two years’ experience in mitral clips since a very detailed paper was published on this last year, and the mitral valve in valve and ring since the results for this procedure were impressively good. In regard to TAVR, 418 sites perform this procedure and the number of cases in 2015 increased from 16,295 in 2014 to 24,808.  Very importantly, mortality and complications have been decreasing each year, probably related to improvements in the technology with smaller catheter and sheath sizes leading to less vascular complications, greater experience of those doing the procedures, a less sick group of patients going initially from those too ill to do an open operation on, to very high risk to high risk according to approval criteria.    The age of the patients however is most often in the 80s.

MedicalResearch.com Interview with: Hywel C. Williams DSc, FMedSci, NIHR Senior Investigator Director of the NIHR Health Technology Assessment Programme http://www.nets.nihr.ac.uk/programmes/hta Professor of Dermato-Epidemiology and Co-Director of the Centre of Evidence-Based Dermatology, http://www.nottingham.ac.uk/research/groups/cebd/index.aspx University of Nottingham, Queen’s Medical Centre, Nottingham University Hospitals NHS Trust, Nottingham UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our clinical trial of 5% imiquimod cream versus surgery for low risk basal carcinoma (BCC) of the skin was first prompted by a shocking lack of randomised controlled clinical trials for what is the commonest form of human cancer. We had conducted a Cochrane systematic review prior to starting the study and found very few long term studies. An emerging literature on imiquimod cream at the time suggested that it might have a clinically useful effect for low risk BCC. All the studies were short term and industry supported, so with the support of Cancer Research UK (UK largest cancer charity), we undertook a large independent study to see how the cream compared to the reference standard of excision surgery with a 4mm margin for low risk superficial and nodular BCC. Our three year results, published in Lancet Oncology, showed that surgery is clearly superior to imiquimod cream, with a success rate (absence of initial failure and no signs of recurrence at 3 years) of 98.4% compared to 83.6% for imiquimod. Nevertheless, the 83.6% success rate is still potentially useful, so we wanted to see whether these 3 year results were sustained. So we followed up your study participants for a total of 5 years and found that the response rates at 5 years were almost the same as those at 3 years (97.7% and 82.5% for surgery and imiquimod respectively). Most treatment failures with imiquimod occurred early on ie in the first year of treatment. Our study shows that if initial treatment works, the benefits are sustained. (more…)

MedicalResearch.com Interview with: Mohammed Al-Omran, MD, MSc, FRCSC Head, Division of Vascular Surgery St. Michael’s Hospital Professor, Department of Surgery University of Toronto MedicalResearch.com: What is the background for this study? What are the main findings? Response: General surgery residency is among the most demanding clinical training programs in medicine. Several studies have suggested surgical residents have a relatively high attrition rate; however, no study has systematically reviewed the overall prevalence and causes of attrition among general surgery residents. We included over 20 studies representing 19,821 general surgery residents in our review. Most studies were from the US. We found the pooled estimate of attrition prevalence among general surgery residents was 18%. Female residents were more likely to leave than male (25% versus 15%), and residents were most likely to leave after their first training year (48%). Departing residents most commonly switched to another medical specialty (such as anaesthesia, plastic surgery, radiology or family medicine) or relocated to another general surgery program. The most common causes of attrition were uncontrollable lifestyle (range of 18% to 88%) and transferring to another specialty (range of 18% to 39%). (more…)
Author Interviews, Breast Cancer, Chemotherapy, Mammograms, MD Anderson, Surgical Research / 12.12.2016

MedicalResearch.com Interview with: Henry M. Kuerer, MD, PhD, FACS Executive Director, Breast Network Programs MD Anderson Cancer Network PH and Fay Etta Robinson Distinguished Professor in Research Department of Breast Surgical Oncology Director, Breast Surgical Oncology Training Program MedicalResearch.com: What is the background for this study? Response: Worldwide, triple negative and HER2 positive breast cancers, combined, account for about 370,000 women diagnosed annually. With recent advances in neoadjuvant systemic therapy (NST, chemotherapy and targeted therapy given before surgery) for both subsets, the pCR (pathologic complete response- when no residual cancer is found) rates found at the time of surgery in these populations can be as high as 60 percent. This high rate of pCR naturally raises the question of whether surgery is required for all patients, particularly those who will receive adjuvant radiation. We believe surgery may potentially be redundant – at least for these two subtypes of breast cancer – because of such a high chance for no evidence of disease at the time of pathological review. If there’s no cancer left after the patient has received chemotherapy and the patient is going to receive local radiation therapy, is surgery actually needed? The challenge has been that standard breast imaging methods cannot accurately predict residual disease after NST. However, by doing the same image-guided percutaneous needle biopsies after neoadjuvant systemic therapy that we do at time of diagnosis, our preliminary research reveals that we may be able to accurately predict which women will have cancer or not.

MedicalResearch.com Interview with: Sophia Akhiyat M.D. Candidate, Class of 2017 The George Washington University School of Medicine and Health Sciences METEOR Fellowship MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study was inspired by one of Choudhry et al,1 in which patients' preferences for skin biopsy result disclosure was surveyed at melanoma clinics affiliated with several academic institutions. We sought to broaden participant inclusion criteria by evaluating patients' preferences at a general dermatology clinic at an academic center. Our findings support that the highest ranked patient-preferred method for receiving skin biopsy results was through an online portal. Patients also reported that the most important factors when selecting a modality for communication were the amount of information given and time available to discuss results. We also observed a relationship between a younger patient age range and online portal experience as well as a preference for biopsy notification via online portal. 1Choudhry A, Hong J, Chong K, et al.

MedicalResearch.com Interview with: Suzanne C. Cannegieter, M.D., Ph.D. Einthoven Laboratory Leiden University Medical Center The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Response: Patients who undergo arthroscopic knee surgery and patients who are treated with casting of the lower leg are at increased risk for venous thromboembolism (VTE). It is uncertain whether thromboprophylaxis is effective in these situations to prevent VTE. For both indications, several trials have been performed to evaluate the effectiveness of anticoagulant prophylaxis. However, an overall risk–benefit balance could not be established because of methodologic shortcomings; hence, there has been reluctance to establish international guidelines regarding the use of anticoagulant therapy for either of these indications.

Author Interviews, Dermatology, Surgical Research, Telemedicine, UT Southwestern / 05.12.2016

MedicalResearch.com Interview with: Rajiv Nijhawan MD Department of Dermatology The University of Texas Southwestern Medical Center Dallas MedicalResearch.com: What is the background for this study? What are the main findings? Response: From a healthcare perspective, we are constantly working to improve access to patients, and telemedicine has proved to be an excellent platform for this goal especially in the field of dermatology. In regards to surgical dermatology, the role of telemedicine has been limited. The ubiquity of smartphones with photograph capability has provided an opportunity for patients to take self-acquired photographs (selfies) easily. Our experience has been that few patients who call with post-operative concerns have major issues (e.g. infection, bleeding, etc.) while the majority of concerns are minor in nature, and patients are often seeking reassurance. Our study shows that the majority of concerns can easily be triaged and managed through patient-directed photography without burdening the patient to take time off work for another appointment, find transportation/travel (many of our patients travel hours for their visits), wait to see the provider, etc. This option of triaging a post-operative concern essentially immediately through the use of patient-directed photographs provides the opportunity for immediate feedback on the patient’s concerns and likely reduces anxiety while making the process as patient-centered as possible. In addition, it allows the physician to be as efficient as possible by not having to overbook his/her schedule to accommodate these often non-urgent concerns. (more…)

MedicalResearch.com Interview with: Allan Doctor, MD Pediatric Critical Care Medicine Professor of Pediatrics and (Associate) Biochemistry Washington University School of Medicine & Saint Louis Children’s Hospital St. Louis, Missouri MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our research team has developed the first nanoscale artificial cells designed to emulate vital functions of natural red blood cells. If ultimately confirmed safe for use in humans, this nanotechnology-based product, called ‘ErythroMer’, could represent a new and innovative alternative to blood transfusions that would be especially valuable in situations where stored blood is needed, but difficult to obtain or use, such as in pre-hospital or battlefield settings. The artificial cells are designed to be freeze-dried, stored for extended periods at ambient temperatures, and simply reconstituted with water for immediate use. This year, the National Academy of Sciences estimated that 30,000 civilian trauma deaths/year are preventable and of these, two-thirds arise from hemorrhage in the pre-hospital phase of care. One key goal for our team is to advance treatment for trauma victims or soldiers in austere environments by initiating resuscitation in the field, particularly when transport is prolonged. ErythroMer could be a blood substitute that medics carry in their pack and literally take it out, add water, and inject. There are currently no simple, practical means to bring transfusion to most trauma victims outside of hospitals. Delays in resuscitation significantly impact outcomes; it is our goal to push timely, effective care to field settings. (more…)
Author Interviews, Frailty, JAMA, Surgical Research, University of Pittsburgh / 01.12.2016

MedicalResearch.com Interview with: Daniel E. Hall, MD, MDiv, MHSc, FACS Associate Professor of Surgery University of Pittsburgh Staff Surgeon VA Pittsburgh Healthcare System Core Investigator VA Center for Health Equity Research and Promotion. PIttsburgh, PA MedicalResearch.com: What is the background for this study? What are the main findings? Response: A growing body of research demonstrates that frailty is a more powerful predictor of postoperative outcomes than risk-prediction models based on age or comorbidity alone. However, it has not been clear if surgeons could intervene on frailty to improve outcomes. This study reports what we believe to be the first ever demonstration that it is not only feasible to screen an entire health system for frailty, but that it is possible to act on that information to improve outcomes. Every patient evaluated for elective surgery was screened for frailty with a brief tool that takes 1-2 minutes to complete. Those identified as potentially frail and thus at greater risk for poor surgical outcomes received an ad-hoc administrative review aimed at optimizing perioperative care. After implementing the frailty screening initiative, we observed a 3-fold increase in long-term survival at 6 and 12 months—even after controlling for age, frailty, and predicted mortality. (more…)

MedicalResearch.com Interview with: Dr. Stefano Savonitto  Director, Division of Cardiology Manzoni Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the last 15 years, there has been a shift from fibrinolytic therapy for STEMI to primary angioplasty, which required a re-organization of the whole STEMI treatment network. Besides the higher reperfusion efficiency of primary angioplasty, as compared to lytic therapy, it has been a global upgrade of the STEMI care system that has reduced the rate of no reperfusion. Elderly patients and women (who are, on average, also older than men) had theoretically the most to gain from this shift, but little data were available to assess this benefit. In the present paper, we have shown that “lack of reperfusion” was reduced dramatically across all age groups and in both sexes, with a progressive and uniform increase in primary angioplasty, and a significant reduction in mortality. Almost as expected, elderly women were the category with the most relevant mortality benefit. Nevertheless, after adjustment for age and other confounders, women continue to experience a higher mortality as compared to men. In the discussion of the paper, we propose some hypotheses for this persistently higher mortality in women. (more…)

MedicalResearch.com Interview with: Alan Karthikesalingam MD PhD, NIHR Academic Clinical Lecturer in Vascular Surgery St George's Vascular Institute London, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for this study was that the typical diameter at abdominal aortic aneurysm (AAA)  repair, and the population incidence of AAA repair, have been known to vary considerably between different countries. This study aimed to observe whether a discrepancy in the population incidence rate of AAA repair between England and the USA was seen alongside a discrepancy in population rates of AAA-related mortality or AAA rupture in those countries.

Author Interviews, Cancer Research, Education, Surgical Research / 22.11.2016

MedicalResearch.com Interview with: Dr. Dmitri Alden MD, FACS Surgical Oncologist, specializes in liver cancer, bile duct cancer, metastatic ovarian cancer and pancreatic cancer at Lenox Hill Hospital, NY Dr. Alden is an advocate of the role of empathy in medicine and discusses his passion for compassionate care in this interview. Please see his bio and website at http://www.liversurgeryny.com. MedicalResearch.com: Why do you feel that empathy is a vital part of treating a patient? Response: Over the last decade many physicians, patients and other professionals began to recognize that medical care is much more than treatment with medications or an act of surgery. Healing involves pain and suffering and dealing with psychological issues connected to the stress of being taken out of one’s normal life routine. Pain is now considered a “vital sign” and only recently it became mandatory to address it properly and document it in a medical record. Empathy in my opinion is a “vital sign” of any relationship that forms between a patient and a medical professional. When expressed genuinely, it makes a tremendous impact on patient’s overall experience and recovery. MedicalResearch.com: How do you define empathy in regards to medical treatment? Response: Empathy is understanding and true genuine caring. Patients and doctors create a unique and very personal relationship built on trust and “chemistry”. The doctor’s ability to express empathy, step in the patient’s shoes, get to know their life, loves, personal problems and to structure care around this unique individual enhances the patient’s belief in the route of treatment chosen and the doctor’s ability to provide a cure. MedicalResearch.com: Do you feel that the medical system doesn't emphasize empathy enough? Response: Doctors are trained without an emphasis on empathy. They focus on acquiring immense amounts of information that need to be learned during medical school and residency. Emotions are currently left to the side in order to succeed. The end product is often a machine that knows what to do in any medical situation but has difficulty to connect on an emotional level. I feel that empathy is also a very important step towards achieving successful outcomes because a patient will feel more invested in following the doctor's advice if he feels there is compassion and understanding.

MedicalResearch.com Interview with: Dr James Spratt Bsc, MD, FRCP, FESC, FACC Spire Edinburgh Hospitals and Spire Murrayfield Edinburgh Spire Shawfair Park Hospital MedicalResearch.com: What is the background for this study? Response: Gender differences exist between male and female patients following routine PCI but data regarding these differences in Chronic Total Occlusions (CTO) Percutaneous Coronary Intervention (PCI) is limited. We maintain a dedicated national (United Kingdom) prospective CTO database contributed to by dedicated CTO PCI operators (lifetime CTO PCI >300). We retrospectively analysed this database from 2011-2015 to compare outcomes and characteristics of male versus female patients undergoing CTO PCI. We attempted to limit the bias of this observational study by propensity matched analysis. (more…)

MedicalResearch.com Interview with: Kamila Mistry, PhD MPH AHRQ MedicalResearch.com: What is the background for this study? Response: Although the overall cesarean section (C-section) rate in the United States has declined slightly in recent years, nearly a third of all births continue to be delivered by C-section—higher than in many other industrialized countries. A number of medical as well as nonmedical factors may contribute to high C-section rates. C-section is the most common surgical procedure performed in the United States. This operation carries additional risks compared with vaginal delivery, such as infection and postoperative pain. A C-section also may make it more difficult for the mother to establish breastfeeding and may complicate subsequent pregnancies. Consensus guidelines from the American Congress of Obstetricians and Gynecologists and other national efforts to improve perinatal care have shown promise in reducing nonmedically indicated C-sections. However, recent research has found wide variation in hospital C-section rates even for low-risk deliveries. (more…)

Mehra, MD, FACC, FESC, FHFSA, FRCP Medical Director, Brigham and Women’s Hospital Heart and Vascular Center Executive Director, Center for Advanced Heart Disease Professor of Medicine, Harvard Medical School Editor in Chief, The Journal of Heart and Lung Transplantation Brigham and Women's Hospital Boston, MA Mandeep R. Mehra, MD, FACC, FESC, FHFSA, FRCP Medical Director, Brigham and Women’s Hospital Heart and Vascular Center Executive Director, Center for Advanced Heart Disease Professor of Medicine, Harvard Medical School Editor in Chief, The Journal of Heart and Lung Transplantation Brigham and Women's Hospital Boston, MA MedicalResearch.com: What is the background for this study? Response: 10% of patients with heart failure and a reduced ejection fraction transition into Advanced Stages of disease where they become unresponsive to life prolonging traditional medications. Such patients typically require intravenous inotropic therapy to preserve cardiac function but most remain profoundly limited in their quality of life. In such cases a heart transplant is desirable but this is an option for only a few patients. Left Ventricular Assist Devices (LVADs) have become the mainstay for treating such patients either while they await a transplant or as a permanent option. However, there are challenges leading to infections, strokes, bleeding and most importantly pump malfunction due to thrombosis of the LVAD itself. The HeartMate 3 LVAD is a centrifugal pump that is designed to overcome the problem of pump thrombosis by virtue of 3 engineering attributes: (a) A frictionless rotor that is based on a fully magnetically levitated platform (b) wide blood flow passages that reduce red cell destruction and (c) an artificial intrinsic pulse that prevents stasis of blood within the pump.

MedicalResearch.com Interview with: Brodie Parent, MD MS General Surgery R4 University of Washington MedicalResearch.com: What is the background for this study? What are the main findings? Response: We already knew that women with a history of bariatric surgery are a high risk group when it comes to childbirth. Our study has confirmed prior data which show that infants from these women are at a higher risk for being premature, low birth-weight, or requiring ICU admission. However, this is some of the first data which looks at their risk over time after recovery from the operation. Data from this study show that risks to the infant are highest in the first 3 years after an operation, and diminish over time. This suggests that women should wait a minimum of three years after an operation before attempting conception. (more…)

Lynch Professor of Urologic Oncology Director of the LeFrak Center for Robotic Surgery Weill Cornell Medicine Urology New York Presbyterian/Weill Cornell New York, NY 10065 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The US Preventative Services Task Force (USPSTF) recommended against PSA testing in men older than 75 years in 2008 and more recently in all US men regardless of age in 2012. This was largely based on a faulty study, the prostate, lung, colo-rectal and ovarian screening study. We demonstrated in May 2016 that this randomized trial did not compare screening to no screening or apples to oranges, as it set out to do. It compared screening to screening. Although controversial, the guidelines were well-intentioned, as recognize that there is over-diagnosis and over-treatment of men with prostate cancer. Given this background, the goal of our study was to explore the downstream consequences of the recommendation against PSA screening. As such, we explored 3 separate databases to characterize national procedure volumes for prostate needle biopsy and radical prostatectomy, or surgery to cure prostate cancer. The main finding was that prostate biopsy numbers decreased by 29% and radical prostatectomy surgeries decreased by 16% when comparing before to after USPSTF recommendations against PSA screening. Therefore practice patterns followed policy. Prostate biopsies are usually performed due to an elevated, abnormal screening PSA. However, it is also performed to monitor low-risk, slow growing prostate cancers. We also found that while the overall number of prostate biopsies decreased, there was a 29% increase in the proportion or percentage of biopsies performed due to active surveillance, or monitoring of low risk prostate cancers which should be done periodically. Therefore we provide the first national study to demonstrate that there is less over-diagnosis and over-treatment of prostate cancer. However, the concern is that we also recently demonstrated that there is more aggressive prostate cancer on surgical pathology for men who go on to radical prostatectomy. They have high grade, higher stage cancers, which have a lower chance of cure. The link is: http://www.prostatecancerreports.org/fulltext/2016/_Hu_JC160708.pdf (more…)

MedicalResearch.com Interview with: Opeyemi O. Fadahunsi, MBBS, MPH Department of Medicine Reading Health System West Reading, Pennsylvania MedicalResearch.com: What is the background for this study? What are the main findings? Response: Transcatheter aortic valve replacement (TAVR) is a minimally invasive approach to managing symptomatic severe aortic stenosis in patients who have a high surgical risk or are deemed to be inoperable. One of the most frequent complications is development of conduction abnormalities requiring permanent pacemaker placement. We compared clinical outcomes in patients requiring permanent pacemaker placement post-TAVR to those not requiring a pacemaker using a large US database called the STS/ACC TVT RegistryTM . We used real-world data of patients undergoing TAVR in the US at 229 sites between November 2011 and September 2014. The frequency of pacemaker placement within 30 days post-TAVR was 6.7% (651 of 9,785 patients). Those who needed a pacemaker within 30 days post-TAVR had longer hospital and intensive care unit stays compared to those who did not. Furthermore, those who needed a pacemaker had a higher risk of death from any cause at one year compared to those who did not get a pacemaker. (more…)

MedicalResearch.com Interview with: Timothy Patton, DO Department of Dermatology Falk Medical Center University of Pittsburgh Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: As dermatologists we are confronted daily with how to manage lesions that are biopsied and diagnosed as dysplastic nevi. These lesions are considered by some to be potential melanoma precursors and by others as benign lesions with little to no malignant potential. Often, particularly for lesions with severe atypia these lesions are re excised. There are no prospective studies or consistent guidelines as to how to manage these lesions. We decided to retrospectively look at the outcome of 451 patients with dysplastic nevi with severe atypia, many of whom had not had their lesions re-excised, who had at least 5 years of follow up to determine if any developed melanoma at the site of the biopsied dysplastic nevus or distantly. We found no cases of metastatic melanoma in patients who did not already have a diagnosis of melanoma. We found two cases of thin melanoma in patients who had their lesions re-excised. Both of those patients were treated with reexcision and did not develop subsequent melanoma metastasis or recurrence. (more…)
