Response: Sexual harassment is a form of discrimination that includes gender harassment, unwanted sexual attention, and sexual coercion. A recent report in Fortune magazine noted that over half of US women have experienced sexual harassment at some point in their lives. Until recently, much of the conversation about sexual harassment in the workplace has been relegated to private discussions behind closed doors. However, the MeToo movement has shined a spotlight on the pervasive nature of sexual harassment in various fields, like media and business world. Although there are more female physicians in practice today than ever before, with women accounting for over 50% of young physicians, sexual harassment and gender disparities continue to plague the field of medicine. Despite the large female representation, gynecologic oncology is not immune from gender disparities. The Society of Gynecologic Oncology is a professional organization of over 2000 physicians, scientists, allied health professionals, nurses, and patient advocates dedicated to the care of patients with gynecologic cancer. As of 2015, 46% of members of the SGO were women, and that number is steadily growing. SGO leadership is also increasingly female – with 2 of the last 3 presidents being women. Despite the large female representation, gynecologic oncology is not immune from gender disparities. The 2015 SGO practice survey noted that while 22% of male Gynecologic Oncologists held the rank of professor, only 11% of their female counterparts held the title. They also noted that the mean annual salary for male physicians was nearly 150,000$ greater than salary for female physicians. Given the fact that there is little objective data on sexual harassment in gynecologic oncology, the objective of our study was to evaluate perceptions of sexual harassment and gender disparities among physician members of the Society of Gynecologic Oncology.

MedicalResearch.com Interview with: Rajat Kalra, MBCh Cardiovascular Division University of Minnesota, Minneapolis MedicalResearch.com: What is the background for this study? Response: New-onset atrial fibrillation after aortic valve procedures is thought to occur frequently after aortic valve procedures, such as transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (AVR). However, the incidence estimates and implications of this new-onset atrial fibrillation in the contemporary era are unclear. We sought to examine the incidence of atrial fibrillation after aortic valve procedures, compare the incidence between TAVI and AVR, and evaluate the associated morbidity and mortality implications using a ‘big data’ approach. This big data approach employed the National Inpatient Sample and was validated in the New York State Inpatient Database. Both are publicly available datasets that are developed as part of the Healthcare Cost and Utilization Project, a federal-state-industry partnership that is sponsored by the Agency for Healthcare Research and Quality.

MedicalResearch.com Interview with: Ashraf Habib, MDChief of the Division of Women’s Anesthesia and Professor of AnesthesiologyDuke University Ashraf Habib, MD Chief of the Division of Women’s Anesthesia Professor of Anesthesiology Duke University  MedicalResearch.com: What is the background for this study? What are the main findings? Response: This was a multicenter study conducted in 13 clinical sites in the United States enrolling patients undergoing elective Cesarean-section and receiving spinal anesthesia. 186 patients were enrolled and randomized to receive EXPAREL, a long-acting, non-opioid option to manage postsurgical pain, administered via transversus abdominis plane (TAP) field block, mixed with plain bupivacaine or TAP block with plain bupivacaine alone. A TAP block numbs the nerves that supply the abdominal wall. We presented the data at the 51st Annual Meeting of the Society of Obstetric Anesthesia and Perinatology (SOAP) in Phoenix, AZ. We aimed to collect clinical evidence that a multimodal postsurgical pain regimen using a TAP block with EXPAREL (bupivacaine liposome injectable suspension) together with regularly scheduled acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) could reduce opioid consumption more so than a standard multimodal pain control approach that combines TAP block with standard bupivacaine, regularly scheduled acetaminophen, and NSAIDs.

This prompted us to tailor and streamline an MBI specifically for surgeons, and to test it in our trainees.

MedicalResearch.com Interview with: hospital-frailty-surgeryKara Anne Rothenberg.MD Postdoctoral Research Fellow, Vascular Surgery Shipra Arya, MD SM FACS Associate Professor of Surgery Stanford University School of Medicine MedicalResearch.com: What is the background for this study? Response: There is a growing body of literature showing that frailty, a syndrome where patients have increased vulnerability to a stressor (such as surgery), is associated with increased postoperative complications, failure to rescue, and hospital readmissions. The Risk Analysis Index (RAI), is an easy to use frailty measurement tool that better predicts postoperative mortality than age or comorbidities alone. As the rates of outpatient surgeries rise nationwide, we noted that most of the surgical frailty studies focus only on inpatient surgeries. Elective, outpatient surgery is generally considered low risk for complications and unplanned readmissions, however we hypothesized that for frail patients, it might not be.

MedicalResearch.com Interview with: Haishan Zeng, PhDDistinguished ScientistImaging Unit - Integrative Oncology DepartmentBC Cancer Research CentreProfessor of Dermatology, Pathology, and Physics, University of British ColumbiaVancouver, BC, Canada Haishan Zeng, PhD Distinguished Scientist Imaging Unit - Integrative Oncology Department BC Cancer Research Centre Professor of Dermatology, Pathology, and Physics, University of British Columbia Vancouver, BC, Canada  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We developed a fast multiphoton microscope system that enables clinical imaging of the skin at the level of cellular resolution. With this system, we can see microstructures inside of the skin without cutting into it. We subsequently conceived the idea of directly treating the microstructures that are responsible for disease. We increased the laser power to generate intense localized heat to destroy the targeted structure. In this study, we demonstrated the feasibility of this new treatment by targeting and closing single blood vessels using our new microscope.

Heng, MD, MPH, FRCSCOrthopaedic Trauma SurgeonAssistant Professor of Orthopaedic SurgeryHarvard Medical School Dr. Heng[/caption] Marilyn M. Heng, MD, MPH, FRCSC Orthopaedic Trauma Surgeon Assistant Professor of Orthopaedic Surgery Harvard Medical School  MedicalResearch.com: What is the background for this study?   Response: The ultimate background for this study does come from the larger context of the opioid epidemic that is seen worldwide but particularly in North America. Orthopaedic surgeons should take responsibility as being among the top prescribers of opioids. The more specific background that led to this specific study was the observation that several colleagues would insist that a drug like hydromorphone was so dangerous that they would not prescribe it but seemed okay prescribing large amounts of oxycodone.  It seemed like an urban myth that the type of opioid was what made it dangerous, so that led us to do the study to see if there was evidence for that.

Yu, MD, MMSc Assistant Professor,  Harvard Medical School Director, Bone Density Center Endocrine Unit, Massachusetts General Hospital MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Roux-en-Y gastric bypass (RYGB) is a popular surgical weight loss procedure.  We have previously shown that gastric bypass leads to rapid high-turnover bone loss. Bariatric procedures are being increasingly performed in older adults, and the clinical consequences of gastric bypass-associated skeletal changes in this vulnerable population have been unclear to date.  Thus, we used Medicare claims data to investigate fracture risk among older adults after gastric bypass, and in comparison to adults who received another bariatric procedure called adjustable gastric banding (AGB), which is thought to have fewer negative bone effects. In our analysis, we found that patients undergoing Roux-en-Y gastric bypass were 73% more likely to fracture than those undergoing AGB. Importantly, we found that hip fracture risk increased nearly 180% after RYGB, and that fracture rates in patients aged 65 or older were similar to the overall group.

Nfonsam, MD, MS, FACS Associate Professor of Surgery Program Director, General Surgery Residency Colon and Rectal Surgery Division of Surgical Oncology University of Arizona, Tucson  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The overall incidence of colon cancer in the United states has gone down in the last few decades. However, there has been a significant increase in the incidence of sporadic colon cancer is young patients (<50 years old). The etiology of this phenomenon is likely multi-factorial. These young patients do present with more advanced disease and with aggressive features. We demonstrated in our study that the colon cancer tumor biology was different between young and older patients. We also singled out a particular gene, Cartilage oligomeric Matrix Protein (COMP) which was significantly over-expressed in young patients and demonstrated its role in cancer proliferation and metastasis and also its potential as a prognostic biomarker since we were able to detect it in plasma.

The results were presented at the American Association of Neurological Surgeons (AANS), April 2019 MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Traumatic brain injury (TBI) is a major cause of death and disability in the US and around the globe. The effects of TBI are often long-lasting, with more than one-third of severe TBI patients displaying a neuromotor abnormality on physical examination 2 years following injury and, yet, there are no effective treatments. The public health implications are staggering: there are approximately 1.4 million new cases of TBI in the US annually, resulting in over 50,000 deaths and 80,000 disabilities; over 5 million Americans currently suffer from long-term disability caused by TBI. A successful neuroregenerative or neurorestorative therapy, such as stem cell implantation, would have significant impact.

MedicalResearch.com: What is the background for this study? What are the main findings? Response: Current literature on women in surgery show that female physicians, particularly those in procedural specialties, face many challenges in balancing responsibilities between work and home. We hypothesized that these challenges may affect career satisfaction more negatively for physician mothers in procedural specialties than those in nonprocedural specialties. In our study, we found that physician mothers in procedural specialties who had more domestic responsibilities were more likely to report a desire to change careers than those in nonprocedural specialties.

Boffa, MD Associate Professor of Thoracic Surgery Yale School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prominent cancer hospitals have been sharing their brands with smaller hospitals in the community.  We conducted a series of nationally representative surveys and found that a significant proportion of the U.S. public assumes that the safety of care is the same at all hospitals that share the same respected brand.  In an effort to determine if safety was in fact the same, we examined complex surgical procedures in the Medicare database. We compared the chance of dying within 90 days of surgery between top-ranked hospitals, and the affiliate hospitals that share their brands.  When taking into account differences in patient age, health, and type of procedure, Medicare patients were 1.4 times more likely to die after surgery at the affiliate hospitals, compared to those having surgery at the top-ranked cancer hospitals.

Lum, MD, FACSProfessor in the Department of Surgery-Division of Surgical Oncology Medical Director of the Breast Health CenterLoma Linda University HealthLoma Linda University School of Medicine Dr. Lum[/caption] Sharon S. Lum, MD, FACS, Professor Department of Surgery-Division of Surgical Oncology Medical Director of the Breast Health Center Loma Linda University Health Loma Linda University School of Medicine  MedicalResearch.com: What is the background for this study?   Response: Anecdotally, we observed that many patients with advanced HER2+ breast cancer have had tremendous responses to the new targeted therapies and the oncologists were referring them back to surgeons for consideration of local regional therapy. While traditionally surgeons have avoided operating on metastatic breast cancer patients due to the patient’s likelihood of dying from their metastatic disease, these HER2+ patients seemed to be doing so well that surgery might make sense. In our surgical oncology clinic, we seemed to be operating more on these patients. Since these patients seemed to be living longer, they might survive long enough for their primary tumor to become a problem for them. However, we did not have any data to support doing surgery in these cases. Prior studies have demonstrated mixed results regarding the survival benefit from surgery for stage IV breast cancer patients, but these were completed prior to routine use of anti-HER targeted therapies, so we wanted to further examine the role of surgery in HER2+ stage IV breast cancer patients.

Diercks, MD, MPH Instructor in Otolaryngology, Harvard Medical School Department of Otolaryngology Massachusetts Eye and Ear Infirmary Boston, Massachusetts  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pediatric tonsillectomy is a commonly performed procedure, representing the second most common ambulatory surgery performed on children in the United States, with over half a million children undergoing the surgery annually.  A major concern for surgeons, patients, and their families is the issue of postoperative pain control as pain can last up to 10-14 days after surgery, be quite severe, and result in readmission to the hospital or ED visits for medications and dehydration. In young children and children with sleep apnea we cannot safely administer narcotic pain medications at home.  This leaves limited options for pain control, including acetaminophen and ibuprofen.  However, there are concerns that ibuprofen could potentially increase bleeding risk after surgery because of its effects on platelet function in the blood.  At baseline, the risk of postoperative hemorrhage within the first two weeks after tonsillectomy is around 4.5%, with about 1-1.5% of children requiring a return to the operating room to control severe bleeding.  Our study set out to show that the risk of severe postoperative bleeding when ibuprofen is given for 9 days after tonsillectomy was not increased compared with the bleeding risk when acetaminophen was administered instead. Our study could not conclude that the risk of bleeding is no different when ibuprofen is used, and was suggestive that the bleeding risk may actually be higher.

Studies to improve clinical outcomes this setting are important. Inhaled anesthetics have pharmacological properties which reduce myocardial infarction size by 50% in laboratory and animal studies and which might decrease postoperative mortality according to aggregated published randomized data.

MedicalResearch.com Interview with: Dr. Jemianne Bautista-Jia,  MD Radiology resident Kaiser Permanente MedicalResearch.com: What is the background for this study? Response: There were a few patient experiences that took me by surprise. I had a patient come to clinic for an initial consultation for uterine fibroid embolization (UFE) and I asked her how she knew about the procedure. She told me that she heard about it on the radio. Another patient who came in told me she heard about it from a close friend. Why did these patients not hear about UFE from their primary physicians? Being a woman, I know that if I had this condition I would prefer a minimally invasive option over surgery. Surgery comes with complications, and I definitely would not want an organ removed from my body if I could avoid it. Therefore I wanted to study UAE to hopefully provide additional objective data to the scientific community to support its use for the treatment of women with fibroids.

Sinai Dr. Khorasani[/caption] Hooman Khorasani, M.D. Cosmetic Surgeon & Mohs Skin Cancer Surgeon Icahn School of Medicine at Mt. Sinai MedicalResearch.com: What is the background for this study? Response: Lipomas are tumors composed of mature fat cells located just beneath the skin surface. They are the most common soft tissue tumor and are estimated to occur in 1% of the population. These benign tumors are more common in overweight individuals, diabetics, patients with elevated serum cholesterol, and those suffering from familial multiple lipomatosis. Most of these tumors are treated for cosmetic reasons; however, large lipomas can also cause significant functional impairment. Traditional treatment includes surgical removal and / or liposuction. Deoxycholic acid is a member of the bile acid family that assists in the breakdown of fat. We investigated the use of deoxycholic acid injections to reduce the size of large lipomas prior to surgical removal.

What are the main findings? Response: Nonmedical prescription opioid use and prescription opioid-related overdose remain significant concerns among adolescents and young adults. Among adolescents and young adults prescribed an opioid after surgery, prior work found that 4.8% of opioid-naïve patients develop new persistent use, filling additional opioid prescriptions at 3-6 months after surgery. This work found associations of persistent use with diagnoses such as chronic pain disorders, depression, anxiety, and prior substance use disorder. It is likely that for young patients, family members may also play an important role in development of new persistent use, but this has not previously been explored. We performed this study to evaluate whether long-term opioid use among family members was associated with prescription opioid fills among adolescents and young adults perioperatively – and we found that opioid-naïve adolescents and young adults who have 1 or more family members with long-term opioid use are more likely to fill at the time of surgery, during recovery, and in the long-term with a near-doubling of rates of new persistent use.

What are the main findings? Response: Delirium is an acute change in mental status characterized by fluctuating disturbances of consciousness and attention. Elderly patients are prone to delirium after surgery; this contributes significantly to post-operative morbidity and can also lead to long-term disability. Our study found that among older adults undergoing hip fracture surgery, both an increased duration of surgery and a general anesthetic are associated with an increased risk for post-operative delirium.​

Response: Nonalcoholic steatohepatitis (NASH), a severe form of nonalcoholic fatty liver disease, is one of the leading causes of liver transplantation. Because of increasing prevalence of obesity in the United States, NASH-related cirrhosis cases are expected to increase in the near future. Unfortunately, there are few pharmacological treatments for NASH, and none with proven long-term benefit. Weight loss can be effective in managing NASH but not many patients can lose the sufficient weight necessary to impact NASH and/or maintain long-term weight loss. In contrast, bariatric surgery can provide long-term weight loss and thus potentially reverse liver damage in cirrhosis. However, bariatric surgery is associated with mortality and morbidity associated with the procedure.

Antunez MS University of Michigan Medical School, Ann Arbor Center for Healthcare Outcomes and Policy University of Michigan, Ann Arbor MedicalResearch.com: What is the background for this study? Response: The American College of Surgeons Commission on Cancer is implementing a National Accreditation Program for Rectal Cancer (NAPRC), aiming to improve and standardize the quality of rectal cancer care in the United States. While this is a commendable goal, previous accreditation programs in other specialties have faced controversy around their uncertain impact on access to care. Furthermore, it is well established that the quality of rectal cancer care is associated with patients’ socioeconomic position. So, the NAPRC could have the unintended consequence of widening disparities and limiting access to high quality rectal cancer care for certain patient populations.

Response: Recent study by Généreux et al (1), using the Placement of Aortic Transcatheter Valves (PARTNER) 2A and 2B data, provided the first framework of a staging system for severe aortic stenosis (AS) that quantifies the extent of structural and functional cardiac change associated with AS and importantly its association with 1-year mortality in patients receiving either surgical or transcatheter AVR (TAVR):
  • Stage 0: No other cardiac damage;
  • Stage 1: LV damage as defined by presence of LV hypertrophy, severe LV diastolic, or LV systolic dysfunction;
  • Stage 2: Left atrium or mitral valve damage or dysfunction;
  • Stage 3: Pulmonary artery vasculature or tricuspid valve damage or dysfunction; and
  • Stage 4: right ventricular damage.

Brown Professor of Anesthesiology Chief of the Division of Clinical and Translational Research Director of the Infrastructure of Quality Improvement, Research and Informatics Washington University School of Medicine St Louis, MO  MedicalResearch.com: What is the background for this study? Response: Postoperative delirium, a temporary state of confusion and inattention, is common in older adults after major surgery. Delirium can be distressing to patients, family members and clinicians. It is associated with longer hospital stays, other medical complications, cognitive decline, and death. Some previous studies have found that using electroencephalography (EEG) monitoring of the brain during general anesthesia decreases the occurrence of delirium following surgery. Therefore we conducted a rigorous study to determine whether using information from the EEG to guide the safe reduction of inhaled anesthetic drugs would prevent postoperative delirium and improve other outcomes in older adults following major surgery.

MedicalResearch.com Interview with: Lene Ring Madsen, MD, Ph.d. Medicinsk Afdeling  Herning Hospitalsenheden Vest Lene Ring Madsen, MD, Ph.d. Medicinsk Afdeling  Herning Hospitalsenheden Vest MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know from previous studies that there is a significant chance of diabetes remission following Roux-en-Y gastric bypass, but most studies evaluate smaller cohorts of selected patients (e.g. from a single center or only patients covered by a specific type of insurance). By using Danish registries, which hold information on all Danish Citizens independent of social- or economic status and have complete follow-up, we wanted to evaluate the Roux-en-Y gastric bypass surgery (RYGB) in a real-world setting. The main findings are that more than 70 % of patients with obesity (BMI>35 kg/m2) and type 2 diabetes treated by RYGB had their diabetes go into remission or every 6-month period in the first 5 years after the procedure. Out of those who were in remission within the first year of follow-up 27% had undergone relapse at 5 years. The most important predictor of a patient not going into remission was if they required insulin to control their disease. Other factors included older age and higher starting HbA1c level. During the more than five years of follow-up, the risk of microvascular complications was 47% lower in the RYGB group than in the control population, with largest decreases in the risk of diabetic retinopathy and diabetic kidney disease. There was a smaller impact on the risk of macrovascular events, which were 24% lower among patients who had received bariatric surgery; however, this difference was not large enough to achieve statistical significance. The 90-day mortality was very low (<0.5%).

What are the main findings? Response: The number of older adults undergoing aortic valve replacement is increasing.  Since these patients are at high risk for complications and functional decline due to preexisting multimorbidity and frailty, the latest guideline (Otto et al. J Am Coll Cardiol 2017;69:1313–46) emphasizes shared decision-making based on patient-centered outcomes.  Despite this recommendation, we witness many decision-making processes are cardio-centric—mainly informed by expected benefit in terms of cardiac-specific measures.  Many patients are not adequately informed about what their daily life would be like after the procedure. In this single-center prospective cohort study, we examined functional status trajectories via assessments of global functional status at 1, 3, 6, 9, and 12 months in 246 patients who underwent transcatheter and surgical aortic valve replacement.  We identified 5 clinically meaningful functional trajectories, ranging from high baseline function-early complete recovery to low baseline function-large and persistent decline.  We were able to predict most likely trajectory as well as best possible and worse possible trajectories using the preoperative frailty index.  Delirium and postoperative complications were also strongly associated with undesirable functional trajectories.

MedicalResearch.com Interview with: [caption id="attachment_46921" align="alignleft" width="114"]Blayne Welk MD, MSc, FRCSC Associate Professor of Surgery St. Joseph's Hospital Western University Dr. Welk[/caption] Blayne Welk MD, MSc, FRCSC Associate Professor of Surgery St. Joseph's Hospital Western University MedicalResearch.com: What is the background for this study? What are the main findings? Response: I found that when I was referred women with midurethral sling complications, they were often quite emotional and described a significant period of time when they struggled with the complications before they were referred to someone to assess them. The study looked at the rate of depression and self-harm behavior of women who had surgery for midurethral sling complications compared to women who did not have midurethral sling complications. I found that there was an increased risk of both of these outcomes among women who had surgery for complications, however this risk was primarily present in younger women.

MedicalResearch.com Interview with: [caption id="attachment_46825" align="alignleft" width="130"]Guillaume Piessen, MD, PhD University Hospital Centre Lille, France Prof. Piessen[/caption] Guillaume Piessen, MD, PhD University Hospital Centre Lille, Franc MedicalResearch.com: What is the background for this study? Response: Patients requiring surgery for esophageal cancer fare better after undergoing a hybrid minimally invasive esophagectomy (HMIE) with a combined laparoscopy+thoracotomy procedure compared to an open esophagectomy (OE), according to results of the MIRO trial published in the last issue of the New England Journal Of Medicine (link article). This French prospective multi-center randomized controlled study was funded by the French National Cancer Institute (Grant n° 1907). The study was conducted by Pr Mariette who sadely passed away in 2017 and Pr Piessen (Department of Digestive and Oncological Surgery, CHU Lille), under the hauspice of FRENCH (Fédération de Recherche EN Chirurgie) and FREGAT (French Eso-Gastric Tumors) working group (https://www.fregat-database.org/fr/). Postoperative morbidity, especially pulmonary complications, affects more than half of patients after open esophagectomy for esophageal cancer. Hybrid minimally invasive esophagectomy (HMIE) combines a laparoscopic abdominal phase with an open thoracotomy, which may have specific advantages including lower rate of pulmonary complications, without laparoscopic tumor dissection limiting potential tumor spillage and easier reproducibility of the technique [12].

Response: The human gastrointestinal tract (GIT) contains several distinct physical environments within the stomach, small intestine (duodenum, jejunum, ileum) and colon that harbor complex microbial communities. Changes in the fecal microbe composition have been described for Roux-en-Y gastric bypass (RYGB), the most effective and durable treatment for morbid obesity, and sleeve gastrectomy (SG).
