Lars Peter Holst Andersen MD., Ph.d. Fellow / Læge, Ph.d. studerende Department of Surgery Herlev Hospital Gastroenheden, Herlev HospitaMedicalResearch.com Interview with: Lars Peter Holst Andersen MD., Ph.d. Fellow / Læge, Ph.d. studerende Department of Surgery Herlev Hospital Gastroenheden, Herlev Hospital Medical Research: What is the background for this study? Dr. Andersen: The sleep hormone, melatonin is diverse molecule. Several experimental animal studies have documented significant antinociceptive effects in a wide range of pain models. In perioperative medicine, administration of melatonin has demonstrated anxiolytic, analgesic and anti-oxidant effects. Optimization of the analgesic treatment in surgical patients is required due to documented inadequate analgesia and the risk of adverse effects and complications caused by commonly used NSAIDs and opioids. Our goal was to investigate if melatonin was able to reduce pain scores or analgesic use in patients undergoing laparoscopic cholecystectomy. (more…)

MedicalResearch.com Interview with: Sayaka Suzuki, MD Department of Clinical Epidemiology and Health Economics, School of Public Health, Faculty of Medicine, Department of Otolaryngology–Head and Neck Surgery, University of Tokyo, Tokyo, Japan Medical Research: What are the main findings of the study? Dr.  Suzuki: We found a slight increase in the risk of severe bleeding requiring surgery for hemostasis in children who were administrated intravenous steroid on the day of tonsillectomy. Physicians should carefully make a decision to use steroids, taking into account patients' choice under being well informed on the risks and benefits of steroid use. (more…)

Terrence Loftus, MD, MBA, FACS Medical Director, Surgical Service & Clinical Resources Banner Health Phoenix, Arizona 85006Medical Research.com Interview with: Terrence Loftus, MD, MBA, FACS Medical Director, Surgical Service & Clinical Resources Banner Health Phoenix, Arizona 85006 Medical Research: What are the main findings of the study? Dr. Loftus: This study demonstrated that a standardized safe surgery program effectively and systematically implemented across a diverse healthcare system resulted in a significant reduction in serious reportable events (SREs), thereby improving the quality of patient care and leading to significant cost avoidance.   For the purposes of the study, SREs were defined as any reported retained surgical item, wrong site, wrong patient or wrong procedure event. Following implementation of the Safe Surgery Program there was a 52% reduction in the SRE rate in the operating rooms and L&D areas in our system. The most dramatic change and greatest area of improvement was in wrong site events which demonstrated a 70% reduction for this type of serious reportable events. This was achieved through a Safe Surgery Program which consisted of three main components.
  • The first component was patient focused procedures. These are steps designed to prevent wrong site, wrong patient or wrong procedure events.
  • The second component was sponge, sharp and instrument count procedures. These are steps designed to prevent retained surgical items.
  • The final component was monthly observational audits that were performed to assess program compliance. (more…)

MedicalResearch.com Interview with: Donna Tepper, M.D. Henry Ford Hospital Medical Research: What are the main findings of the study? Dr. Tepper: We looked at 94 patients who underwent bariatric surgery at Henry Ford from 2003 through 2013. Of those, 47 subsequently had body recontouring procedures, such as body lift, abdominoplasty (tummy tuck), arm lift, thigh lift, face lift.  We recorded the patients’ body mass index prior to bariatric surgery, and then again at 6 months, 1, 2.5, 4, and 5 years.  Of the patients who underwent contouring surgery, the average decrease in BMI was 18.24 at 2.5 years, compared to a statistically significant 12.45 at 2.5 years for those who did not have further surgery.  This is statistically significant.  This 3 point change in BMI is an 18-21 pound difference depending on patient height.  Furthermore, the BMI in the body contouring group continues to be lower at 4 and 5 years from bariatric surgery compared to the bariatric surgery alone group.

Michael S. Calderwood, MD MPH Department of Population Medicine Harvard Medical School and Harvard Pilgrim Health Care Institute Boston, MAMedicalResearch.com Interview with: Michael S. Calderwood, MD MPH Division of Infectious Diseases Brigham and Women's Hospital Boston, MA Medical Research: What are the main findings of the study? Dr. Calderwood: "In our study, we found that the risk of surgical site infection (SSI) following total hip arthroplasty and coronary artery bypass graft (CABG) surgery is higher for Medicare patients undergoing surgery in U.S. hospitals with lower surgical volume. This suggests that volume leads to experience, and experience leads to improved outcomes." "We found a significantly higher risk of surgical site infection in U.S. hospitals performing <100 total hip arthroplasty procedures and <50 CABG procedures per year on Medicare patients. In the lowest volume hospitals, 1 out of 3 infections following total hip arthroplasty and 1 out of 4 infections following CABG were in excess of expected outcomes based on experience in the highest volume hospitals."

David Plurad, MD Los Angeles Biomedical Research In MedicalResearch.com Interview with: David Plurad, MD Los Angeles Biomedical Research Institute. Medical Research: What are the main findings of the study? Based on a survey of patients with traumatic brain injuries, a group of Los Angeles Biomedical Research Institute researchers found those who tested positive for tetrahydrocannabinol (THC), the active ingredient in marijuana, were more likely to survive than those who tested negative for the illicit substance. We surveyed 446 patients who were admitted to a major urban hospital with traumatic brain injuries between Jan. 1, 2010, and Dec. 31, 2012, who were also tested for the presence of THC in their urine. We found 82 of the patients had THC in their system. Of those, 2.4% died. Of the remaining patients who didn't have THC in their system, 11.5% died. While most - but not all - the deaths in the study can be attributed to the traumatic brain injury itself, it appears that both groups were similarly injured. The similarities in the injuries between the two groups led to the conclusion that testing positive for THC in the system is associated with a decreased mortality in adult patients who have sustained traumatic brain injuries.

Dennis Kim, MD Los Angeles Biomedical Research Institute Researcher MedicalResearch.com Interview with: Dennis Kim, MD Los Angeles Biomedical Research Institute Researcher Medical Research: What are the main findings of the study? Dr. Kim: Laparoscopic cholecystectomy, a minimally invasive procedure to remove the gallbladder, is one of the most common abdominal surgeries in the U.S. Yet medical centers around the country vary in their approaches to the procedure with some moving patients quickly into surgery while others wait. Our study found gallbladder removal surgery can wait until regular working hours rather than rushing the patients into the operating room at night. The gallbladder is a pear-shaped organ on the upper right side of the abdomen that collects and stores bile, a digestive fluid produced by the liver. Gallbladders may need to be removed from patients who suffer pain from gallstones that block the flow of bile. In a laparoscopic cholecystectomy, surgeons insert a tiny video camera and special surgical tools through small incisions in the abdomen to remove the gallbladder. Occasionally, surgeons may need to create a large incision to remove the gallbladder, and this is known as an open cholecystectomy. We conducted a retrospective study of 1,140 patients at two large urban referral centers who underwent gallbladder removal surgeries. We found 11% of the surgical procedures performed at night (7 a.m.-7 p.m.) were converted to the more invasive procedure, open cholecystectomies. Only 6% of those who underwent the surgery during the day required the more invasive form of surgery. (more…)

Malinoski, MD, FACS Assistant Chief of Surgery – Research and Education Chief, Section of Surgical Critical Care Portland VA Medical Center Associate Professor of Surgery Oregon Health & Science University Portland, OR 97207 Medical Research: What are the main findings of the study?  Dr. Malinoski: Our two main findings are that the status of the DMG Bundle prior to organ recovery, at the end of the OPO donor management process, is the most predictive of the number of organs that will be transplanted per expanded criteria donor (ECD) and that the absolute increase in the number of individual DMG elements achieved over time also appears to be relevant.  Taken together, these two findings suggest that the number of organs that will be transplantable from each donor is not necessarily predetermined by their age, comorbidities, and pre-neurologic death condition, but that active critical care management has the ability to affect outcomes and reassessing each donor’s condition over time is necessary.

Dr. Dee Fenner, M.D. Professor of Obstetrics and Gynecology Director of Gynecology University of MichiganMedicalResearch.com Interview with: Dr. Dee Fenner, M.D. Professor of Obstetrics and Gynecology Director of Gynecology University of Michigan MedicalResearch.com Editor’s note: American Medical Systems Inc. (AMS), a subsidiary of Endo International plc (Nasdaq: ENDP) (TSX: ENL), released top-line results from its TRANSFORM study that show the investigational TOPAS™ System improves fecal incontinence in women. The results show that over a 12 month period, 69% of women suffering from fecal incontinence who were implanted with the TOPAS™ System experienced at least a 50% reduction in weekly incontinence episodes and experienced a durable, consistent effect across the study period. The results were presented in Cape Town, South Africa at the International Society of University Colon & Rectal Surgeon (ISUCRS) Congress. Dr. Fenner, a primary investigator of the study, kindly answered the questions below: Medical Research: How common/prevalent is the problem of fecal incontinence in women? Dr. Fenner: Fecal incontinence, also known as accidental bowel leakage (ABL), is estimated to affect nearly 11 million women and 10% of women over the age of 20 in the United States.1,2 Additionally, nearly one in five women over the age of 45 experience ABL at least once a year.3 (more…)

Chen, MD, FACS, FAACS Georgia Center for Facial Plastic Surgery, Evans, Ga and the Division of Facial Plastic and Reconstructive Surgery, Department of Otolaryngology–Head and Neck Surgery Georgia Regents University, August, Ga Medical Research: What is the significance of the study? Dr. Chen : This is the first time that facial rejuvenation surgery using surgical approaches in three planes combined with ablative resurfacing has been reported in the medical literature. This approach was not previously thought possible in a single surgical setting because of the concern about disrupting the facial blood supply that may result in loss of the skin. The study demonstrates the safety of this “Total Face” approach. This approach allows simultaneous tightening of the jawline and neck, recreating the lost youthful volume of the midface region, and restoring of the smooth skin texture so characteristic of a young face. This allows for a more complete or “Total Face Rejuvenation” for patients while allowing them the flexibility for a single recovery period or downtime. (more…)

Dr. Juliane Bingener-Casey, M.D. Mayo Clinic in Rochester, Minn.MedicalResearch.com Interview with: Dr. Juliane Bingener-Casey, M.D. Mayo Clinic in Rochester, Minn Medical Research: What are the main findings of the study? Dr. Bingener: Other investigators have shown that preoperative quality of life is a predictor for postoperative survival in colon and pancreas cancer surgery. In this study we looked as preoperative quality of life as a predictor for postoperative complications. The main findings of the study were that patients who had a deficit in their quality of life before surgery had a 3 times higher risk of a serious complication before leaving the hospital than patients who had normal quality of life (16% vs 6 %), independent of gender, race, tumor stage or laparoscopic or open colectomy. Patients with serious complications before leaving the hospital also were older and had more other medical problems than patients without complications. Further, patients who had a complication stayed in the hospital longer and their postoperative quality of life was worse (more…)

Ian Gilron, MD, MSc, FRCPC Director of Clinical Pain Research Professor of Anesthesiology & Perioperative Medicine, Biomedical & Molecular Sciences, and Center for Neuroscience Studies Queen's University Kingston General Hospital, Kingston, Ontario, CanadaMedicalResearch.com Interview with: Ian Gilron, MD, MSc, FRCPC Director of Clinical Pain Research Professor of Anesthesiology & Perioperative Medicine, Biomedical & Molecular Sciences, and Center for Neuroscience Studies Queen's University Kingston General Hospital, Kingston, Ontario, Canada Medical Research: What are the main findings of the study? Dr. Gilron: Pain is the most common symptom which prevents recovery from surgery. Even with the best available treatments today, many patients still suffer from moderate to severe pain after surgery. Antidepressants - drugs used to treat depression - are also proven effective for treating chronic pain due to nerve disease and fibromyalgia. However, there has been much less research on the effects of antidepressant drugs on pain after surgery. Our group conducted a systematic review of all published clinical trials of antidepressant for post surgical pain. Slightly more than half of these studies suggested some benefit of these drugs but the details of this review led us to conclude that there is not yet enough evidence to recommend these medications for post surgical pain treatment. Given the possibility that these medications could be useful treatments for pain after surgery, we believe that future studies of higher scientific quality and which involve larger numbers of patients should be carried out in the hopes of finding safer and more effective treatments for pain after surgery.

The half that went home was younger and had lower WBC counts, lower neutrophils and less people with elevated temperature than the patients immediately admitted. Of the half that went home, 31% returned at least once to the ED within 30 days and 20% were admitted to undergo urgent cholecystectomy after the return visit, 55% percent of those within 7 days of the initial ED visit. Patients who failed the elective treatment plan had similar WBC counts but were more likely to have an ASA >3, slightly higher creatinine and higher average maximum VAS pain score. Patients who were less than 40 years old or older than 60 years were more likely to fail the elective pathway.” (more…)

Henry M. Spinelli, MD, PC Plastic & Reconstructive Surgery 875 Fifth Avenue New York, NY 10065MedicalResearch.com Interview with: Henry M. Spinelli, MD, PC Plastic & Reconstructive Surgery 875 Fifth Avenue New York, NY 10065 Medical Research: What are the main findings of the study? Dr. Spinelli: Briefly, we polled approximately 26,000 plastic surgeons by way of membership in the International Society of Aesthetic Plastic Surgeons (ISAPS), American Society for Aesthetic Plastic Surgery (ASAPS) and American Society of Plastic Surgeons (ASPS) and collated this data and published it in Aesthetic Plastic Surgery (the Blue Journal), the official journal of ISAPS. This preliminary study was initiated given the current and past healthcare and cosmetic medical/surgical care climate both in the United States and worldwide. As a background, when it comes to injectables (botox and fillers) there is not a united consensus on a state by state basis in the USA and from country to country worldwide. Additionally, the regulations and laws governing the administration of botox and injectables is in a constant flux. For instance, the UK allowed beauticians in the past to administer these substances however they are now banned from legal administration of these products. Alabama, only allows physicians (dermatologists and plastic surgeons) to purchase and administer botox and injectables whereas the medical board of California states that physicians can perform the procedure or oversee licensed registered nurses, licensed vocational nurses, or physicians assistants. Similarly, dentists in some states are permitted to administer these agents. It would be a bad idea for any physician working with botox to take Advanced Botox Training to reduce the possibility of medical misdemeanors. At the present time few studies have directly assessed the capability of various providers to administer cosmetic injections. When people schedule a consultation for plastic surgery, they are often looking for things like a younger face or a nicer body. The answer to the previous question will become more important as the demand for these procedures continues to grow and an increasing number of practitioners and different Plastic Surgeon from a variety of backgrounds enter the field to meet demand. This study aimed to help define the role of various practitioners in an increasingly more competitive environment for injectables and to explore the relationship between patient and injectable provider in order to improve patient satisfaction and outcomes. When asked to rank patients’ perceptions of various providers according to their expertise in administering Botox and dermal fillers, responders ranked plastic surgeons and dermatologists as most capable (96%) then nurses in plastic surgery and dermatology (3%). Gynecologists (<1%), dentists (<1%) and nurses in other fields (<1%) all received nearly equivalent numbers of “most capable” rankings. When asked to rank patients’ perception of various providers according to their inability to administer Botox and dermal fillers, nurses in other fields were most frequently ranks as least capable (63%) followed by dentists (26%), gynecologists (12%), plastic surgeons and dermatologists (2%) and nurses in plastic surgery and dermatology (1%).

Mads E. Jørgensen, M.B. University of Copenhagen, DenmarkMedicalResearch.com Interview with: Mads E. Jørgensen, M.B. University of Copenhagen, Denmark Medical Research: What are the main findings of the study? Answer: We included all patients undergoing non-cardiac surgery in 2005-2011, which were then categorized by time elapsed between stroke and surgery. Patients with a very recent stroke, i.e. less than 3 months prior to surgery, had a significant 14 times higher relative risk of 30-day MACE following surgery, compared with patients without prior stroke. Patients with a more distant stroke had a 2-5 fold higher risk of MACE following surgery, and still significantly higher than risks in patients without prior stroke. An additional model including time between stroke and surgery as a continuous measure showed a steep decrease in risks of perioperative MACE during the first 9 months. After 9 months, an increase in time between stroke and surgery did not further reduce the risks. The results for 30-day all-cause mortality showed similar patterns, although estimates were not as dramatic as for 30-day MACE. When analyzing the MACE components individually, we found that recurrent strokes were the main contributor to the high risk of MACE. A history of stroke any time prior to surgery was associated with a 16 fold increased relative risk of recurrent stroke, compared with patients without prior stroke. We also performed analyses stratified by surgery risk as low- (OR for stroke anytime, 3.97; 95% CI, 2.79-5.66), intermediate- (OR for stroke anytime, 4.46; 95% CI, 2.87-5.13) and high-risk (OR for stroke anytime, 1.98; 95% CI, 1.20-3.27), which were somewhat challenged in power. However, results indicated that stroke associated relative risk was at least as high in low and intermediate-risk surgery as in high risk surgery. (more…)

Payton Professor Assistant department chair Department of Physical Therapy Virginia Commonwealth University MedicalResearch: What are the main findings of the study? Dr. Riddle: We used a classification system developed by researchers in Spain in the late 1990s and found that classifications of appropriate, inappropriate and inclusive ratings for persons undergoing knee replacement surgery were  44.0%, 21.7%, and 34.3%, respectively. We studied 175 persons who underwent unilateral total knee replacement in the Osteoarthritis Initiative study, an NIH and privately funded multi-year cohort study of persons with are at high risk for knee osteoarthritis. These findings need to be considered cautiously because the classification system was developed more than 15 years ago and was designed to place greatest priority on persons with end stage knee osteoarthritis and severe pain and functional loss.

Frank H. Morriss, Jr., MD, MPH Professor of Pediatrics  - Neonatology University of Iowa Carver College of MedicineMedicalResearch.com Interview with: Frank H. Morriss, Jr., MD, MPH Professor of Pediatrics  - Neonatology University of Iowa Carver College of Medicine   MedicalResearch: What are the main findings of the study? Dr. Morriss: Our aim was to assess the association between surgery performed during the initial hospitalization of very low- birth-weight infants and subsequent death or neurodevelopmental impairment at 18-22 months’ corrected age. We conducted a retrospective cohort analysis of patients who were prospectively enrolled in the National Institute of Child Health and Human Development Neonatal Research Network Generic Database from 1998 to 2009. Surgery was classified by the expected anesthesia type as either major surgery that likely would have been performed under general anesthesia; or minor surgery, that is, procedures that could have been performed under non-general anesthesia and in general were shorter in duration. There were 2,186 major surgery patients and 784 minor surgery patients and more than 9,000 patients who did not undergo surgery. We found that any surgical procedure  increased the adjusted risk of death or neurodevelopmental impairment in low birth weight infants by about 30%. Not all surgical procedures were associated with increased risk, however. Compared with those who did not undergo surgery, patients  who were classified as having major surgery had a risk-adjusted odds ratio of death or neurodevelopmental impairment of 1.52 (95% confidence interval 1.24-1.87). However, those who were classified as having minor surgery had no increased adjusted risk. Among survivors who had major surgery compared with those who did not undergo surgery the risk-adjusted odds ratio for neurodevelopmental impairment was 1.56 (95% confidence interval 1.26-1.93), and the risk-adjusted mean Bayley II Mental Developmental Index and mean Psychomotor Developmental Index values were significantly lower.

Brooke, M.D., Ph.D. Assistant Professor of Surgery Division of Vascular Surgery University of Utah School of Medicine MedicalResearch: What are the main findings of the study? Dr. Brooke: This study was designed to evaluate whether high-risk surgical patients who visit a primary care provider (PCP) during the early period following hospital discharge are less likely to be readmitted within 30-days.  We examined this question by performing a retrospective cohort analysis of Medicare beneficiaries (2003-2010) who underwent a high risk surgery (open thoracic aortic aneurysm repair) as well as a control group of patients who underwent a lower risk surgical procedure (open ventral hernia repair), and then determining whether there was evidence of early PCP follow-up. In risk-adjusted analyses, we found that early primary care provider-follow-up was associated with a significant lower likelihood of 30-day readmission for high-risk patients undergoing open thoracic aortic aneurysm repair, particularly if a post-operative complication had occurred.  In comparison, early primary care provider follow-up did not have a significant effect on lowering readmissions in uncomplicated patients and those undergoing lower-risk operations such as ventral hernia repair.

Dr. Chang: At 18 months after surgery, weight percentiles in the study group increased by a mean of 6.3 percentile points, and body mass index percentiles increased by a mean of 8.0 percentile points. The greatest increases in weight percentiles were observed in children who were between the 1st and 60th percentiles for weight and younger than 4 years at the time of surgery. An increase in weight percentile was not observed in children who preoperatively were already above the 80th percentile in weight. (more…)
