MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Traditional medicine had a paternalistic approach but more recent changes have transitioned into shared decision making and a patient centered approach. However, current research has not addressed the mode of communicating bad news to patients.

This study was designed to look at trends in modes of communication of a breast cancer diagnosis. This study identified a trend for patients to receive a diagnosis of breast cancer over the telephone in more recent years. Also noted was that of those receiving the diagnosis in person 40% were alone.

MedicalResearch.com: What is the background for this study?

Response: The search for non-drug approaches to chronic pain is a major recommendation in many recent guidelines for both pain management and reduction in the use of opioids. Surgical and invasive procedures are non-drug approaches often used for pain conditions like back pain and arthritis, so good evidence is needed to determine the safety and efficacy of these procedures. Properly done randomized, placebo controlled trials are the best way (the gold standard) to get that evidence, so we did a thorough evaluation of such research, using standard systematic review and meta-analysis methods.

MedicalResearch.com: What is the background for this study?

Response: Firearm-related mortality is a public health issue. However, in the US, due in part to lack of funding, there is not enough research to inform the debate about firearms.

The question our group sought to answer was to understand if the presence of a semi-automatic weapon increased the number of victims killed or hurt during an active shooter incident. We chose to focus on these incidents given the availability of an FBI database detailing these active shooter incidents based on a strict definition and the similarities between such incidents that make a comparison valid.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Cosmetic and functional rhinoplasty (nasal surgery) is the most common procedure we perform and traditionally post operative pain medication includes opioids.

In light of the recent opioid epidemic, we wished to investigate if patients pain was being treated over-treated by surgeons.

Of 173 Rhinoplasties that we performed, the majority of patients received post operative opioid tablets (an average of 28 tablets).  However 11% of patients did not fill these prescriptions at all, and only 2 of the 178 patients required refills.

We believe patients experienced less pain than surgeons anticipated.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The robotic surgical approach has gained significant traction in the U.S. market despite mixed opinions regarding its clinical benefit. A few recent randomized trials have suggested there may be no clinical benefit of the robotic approach for some surgical procedures over the more traditional open or laparoscopic (“minimally-invasive”) approaches.

Previous studies have also suggested the robotic approach is very expensive, but until our study, there was no benchmark for the true costs (to the hospital) of using the robotic platform.

Our study analyzed financial statements from the main supplier of robotic technology. We found that the use of robotic surgery has increased exponentially over the past decade from approximately 136 thousand procedures in 2008 to 877 thousand procedures in 2017. The majority of these procedures were performed in the United States. While most people think of the robotic approach in urologic and perhaps gynecologic surgery, the fastest growing segment has been general surgery, for procedures such as colorectal resections, hernia repairs and gallbladder removals. In total, over 3 billion dollars was spent by hospitals to acquire and use robotic platforms in 2017 with 2.3 billion dollars in the United States. This equates to nearly $3,600 per procedure performed.

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: We performed this study to compare two methods of replacing a diseased aortic valve in young and middle-aged adults: using an artificial mechanical valve (mechanical aortic valve replacement) versus using the patient’s own pulmonary valve (Ross procedure).

The study was a meta-analysis of existing literature that included more than 3,500 adult patients. It found that those who underwent the Ross procedure were 46 per cent less likely to experience death from any cause than patients who underwent mechanical aortic valve replacement. Patients in the Ross group were also less likely to suffer from a stroke or major bleeding, and had better quality of life. Patients who underwent the Ross procedure were more likely to need late reoperation, but this did not negatively impact their survival. Continue reading

Percutaneous Repair or Medical Treatment for Secondary Mitral Regurgitation?

MedicalResearch.com Interview with:
Jean François Obadia Adult Cardiovascular Surgery and Transplantation Louis Pradel HospitalJean François Obadia MD PhD

MedicalResearch.com: What is the background for this study?

-By definition a secondary MR concerns a normal valve or sub normal valve inside a dilated heart with poor LV function in a population of Heart failure patients. It is perfectly established today that secondary MR is a predictor of poor clinical outcomes of thissevere population.

-Therefore,it has been proposed to treat those regurgitation either by surgery (mainly the downsizing anuloplasty) or by percutaneous technique like the mitraclipwhich has been used more and more frequently recently.

-However, a beneficial effect on hardclinical outcomes has never been provedandwe still don’t know if those regurgitations need to be corrected or not, We still don’t Know if the regurgitation is the cause, the consequence or just a marker of poor prognosis.

-In this context according to the guidelines, there is a low level of evidence to support those treatments, and Europe and US Guidelines call for prospective randomized studies in this severe population.​

And this excatly what we have done with MITRA-FR

Feinberg School of Medicine

MedicalResearch.com: What is the background for this study?

Response: For the purposes of our study, non-invasive procedures included laser and light treatments (for brown spots, blood vessels, wrinkle reduction, scar treatment, hair removal), chemical peels, and non-surgical skin tightening and fat reduction (with radiofrequency energy, cold treatment, or ultrasound). These noninvasive treatments do not even break the skin, and are applied on top of the skin

Then we have minimally invasive procedures, which include those that just barely break the skin, but are like getting a shot, and don’t require cutting and sewing the skin as in traditional surgery. These minimally invasive procedures include filler and neuromodulator injections to fill out the sagging aging face while reducing lines and wrinkles, as well as liposuction through tiny openings to suck out excess fat. All of these procedures and many more are available but if you do want to have a cosmetic procedure then make sure you seek out a reputable cosmetic surgeon such as Lisa Rush.

In the old days, cosmetic treatments meant getting traditional plastic surgery, like a face lift or tummy tuck. These required general anesthesia, cutting and sewing the skin, significant risk of scarring, and days to weeks of recovery time. More recently, dermatologists have pioneered noninvasive and minimally invasive procedures, such as those I just described, which provide many of the same benefits as traditional plastic surgery without the risk, scars, and downtime, for example, somewhere like Rhinoplasty NYC talk about Rhinoplasties with noninvasive methods. Now these minimally invasive and noninvasive treatments have become more popular than traditional cosmetic surgery. Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Although women make up half of medical student graduates in 2018, they only comprise a third of applicants to general surgery. Studies suggest that lifestyle concerns and perceptions of conflict between career and family obligations dissuade students from the field.

After entering surgical residencies, women residents have higher rates of attrition (25% vs 15%) and cite uncontrollable lifestyle as a predominant factor in leaving the field. Surgeons face reproductive challenges including stigma against pregnancy during training, higher rates of infertility, need for assisted reproduction, and increased rates of pregnancy complications. However, until recently, studies capturing the viewpoints of women who begin families during training have been limited. Single-institution experiences have described mixed experiences surrounding maternity leave duration, call responsibilities, attitudes of coworkers and faculty, and the presence of postpartum support.

Earlier this year, our group presented findings of the first national study of perspectives of surgical residents who had undergone pregnancy during training. A 2017 survey was distributed to women surgical residents and surgeons through the Association of Program Directors in Surgery, the Association of Women Surgeons and through social media via twitter and Facebook. Responses were solicited from those who had at least one pregnancy during their surgical training.

39% of respondents had seriously considered leaving surgical residency, and 30% reported they would discourage a female medical student from a surgical career, specifically because of the difficulties of balancing pregnancy and motherhood with training (JAMA Surg 2018; July 1; 153(7):644-652).

These findings suggested the challenges surrounding pregnancy and childrearing during training may have a significant impact on the decision to pursue or maintain a career in surgery. The current study provides an in-depth analysis of cultural and structural factors within residency programs that influence professional dissatisfaction.

We found that women who faced stigma related to their pregnancies, who had no formal maternity leave at their programs, and who altered subspecialty training plans due to perceived challenges balancing motherhood with the originally chosen subspecialty were most likely to be unhappy with their career or residency.

Statins May Reduce Need For Surgery in Chronic Subdural Hematoma

Chairman, II, VII Chinese Medical Association of Neurosurgery
President, Tianjin Medical University General Hospital,
China  

MedicalResearch.com: What is the background for this study?

Response: The elderly population is growing dramatically world widely, especially in China. The incidence of chronic subdural hematoma has been rising over the past years. Although the surgery is not a difficult process, the risk of death and recurrence persist, and the affliction and economic expenditure of the patients are relatively higher in the elderly. For these reasons, it is urgent to develop novel pharmacological therapies with sufficient safety and efficacy. 

It has been known that the high expression of VEGF and inflammatory factors in chronic subdural hematoma can lead to abundant angiogenesis of immature vessels on the wall of hematoma. In our previous study, patients with chronic subdural hematoma have impaired ability to promote vascular maturation. For example, the number of endothelial progenitor cells in circulating blood is about 67% of the healthy individuals with similar age. 

Atorvastatin can mobilize endothelial progenitor cells to reduce inflammation. It increases the number of circulating endothelial cells that are inversely correlated with the volume of hematoma. We have demonstrated that atorvastatin can promote endothelial cell formation and reduce the leakage of endothelial cell barrier in vitro. Results from in vivo experiments in animal models of subdural hematoma suggest that atorvastatin can promote the maturation of blood vessels and reduce inflammation on the margin of hematoma, and thus improve the neurological outcome.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We know that renal function decreases as we age, and we know that decreased renal function is independently associated with increased mortality. This is why medical society guidelines recommend partial nephrectomy, which preserves kidney tissue and function, over radical nephrectomy for the treatment of the smallest kidney cancers, stage T1a tumors, which are under 4 cm diameter. Paradoxically, though, we know older patients are more likely than younger patients to receive radical nephrectomy for these smallest tumors, probably because it’s a simpler surgery than partial nephrectomy.

Percutaneous ablation, focal tissue destruction using heat or cold emanating from the tip of a needle, is a newer, image-guided, minimally-invasive, tissue-sparing treatment for solid organ tumors. We wanted to test how well percutaneous ablation would compare to partial nephrectomy and radical nephrectomy for these smallest kidney cancers.

We found that percutaneous ablation was associated with similar 5-year overall and cancer-specific survival compared to radical nephrectomy. At the same time, ablation was associated with significantly lower rates of new-onset chronic renal insufficiency and one-fifth as many serious non-urological complications than radical nephrectomy within 30 days of treatment. These were complications, such as deep venous thrombosis or pneumonia, that resulted in emergency department visits or new hospital admissions. The outcomes of percutaneous ablation compared with partial nephrectomy were somewhat less clear, though ablation was again associated with fewer perioperative complications. Continue reading

Surgery For Spondylolisthesis (Spinal Stress Fractures) Reduced Chances of Opioid Dependence

University of Louisville

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: This study stems from the observed opioid crisis in the United States in recent years. Opioids are used in the management of pain. In the spine population, back pain is one of the main conditions for which opioids are consumed.

A frequent cause of that pain is degenerative spondylolisthesis. We aimed to evaluate the effect of surgery, which has been shown to improve outcomes, on opioid dependence. We found that surgery is associated with reduced odds of opioid dependence.

MedicalResearch.com: What should readers take away from your report? 

Response: One interesting finding that we observed is that patients are twice less likely to become opioid dependent than they are to become dependent after surgery. However, an important note to keep in mind is that about 10% of patients will be opioid dependent after surgery (about 6% prior non-dependent and 4% prior dependent).  

MedicalResearch.com: What recommendations do you have for future research as a result of this work? 

Response: Surgery has been proven to improve clinical outcomes and quality of life for patients with degenerative spondylolisthesis. Future research should explore why some patients remain or become opioid dependent after surgery.

It would also be interesting to look at the effect of other treatments for degenerative spondylolisthesis (such as epidural steroid injections for example) on opioid dependence.

MedicalResearch.com: Is there anything else you would like to add?

Response: Spine surgeons should have systems that help them recognize patients who are likely to become opioid dependent after surgery. Our paper discusses factors to watch for such as younger age, prior dependence, etc… This would help provide targeted attention and hopefully combat the ramping opioid crisis.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Thirteen states have laws that require abortions to be provided in Ambulatory Surgery Centers (ASCs); many of these laws apply only in the second trimester.  We examined outcomes from more than 50,000 abortions provided in two facility types:  Ambulatory Surgery Centers and office-based settings.

We found that there was no significant difference in abortion-related complications across facility type; in both settings, about 3.3% had any complication and about 0.3% had a major complication.  There also was no significant difference in complications across facility types for second trimester and later abortions.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: We studied whether patients’ mortality rate differ based on age and sex of surgeons who performed surgical procedures. Using a nationally representative data of Medicare beneficiaries aged 65-99 years who underwent one of 20 major non-elective surgeries, we found that patients treated by older surgeons have lower mortality than those cared for by younger surgeons, whereas there was no difference in patient mortality between male and female surgeons. When we studied age and sex together, we found that female surgeons at their 50s had the lowest patient mortality across all groups.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Little is known about outpatient procedures that can be considered invasive but are not conducted in a surgical operating room. These procedures are largely neglected by quality or patient safety surveillance programs, yet they are increasingly performed as technology improves and the U.S. population gets older.

We assessed the rate of invasive procedures across five specialties, urology, podiatry, cardiology, interventional radiology and gastroenterology in the Veterans Health Administration between fiscal years 2012 and 2015. Our analysis included examining the rates of post procedure emergency department visits and hospitalizations within 14 days and the key patient, procedure or facility characteristics associated with these outcomes. We found varying rates of post procedure ED visits and hospitalizations across the specialties with podiatry accounting for a high volume of invasive outpatient care but the lowest rate of postoperative utilization (1.8%); in contrast, few of the procedures were in interventional radiology, but the postoperative utilization rate was the highest at 4.7%. In a series of logistic regression models predicting post procedure healthcare utilization for each specialty, we observed significantly higher odds of post procedural outcomes for African American patients compared to white patients.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Michigan was one of several states to expand Medicaid. Current evaluations of the Michigan Medicaid expansion program have noted increases in primary care services and health risk assessments, but less work has evaluated its role within a specialty service line. There has been concern among some that Medicaid patients, who have traditionally lacked access to preventive services, may be at high risk for poor clinical outcomes if provided increased access to cardiovascular interventions.

Using data from two physician-led quality collaboratives, we evaluated the volume and outcomes of percutaneous coronary interventions and coronary artery bypass grafting 24mos before and 24mos after expansion. We noted large-scale increased access to both percutaneous coronary interventions (44.5% increase) and coronary artery bypass grafting (103.8% increase) among patients with Medicaid insurance. There was a decrease in access for patients with private insurance in both cohorts. Nonetheless, outcomes (clinical and resource utilization) were not adversely impacted by expansion.  Continue reading

OviTex Reinforced BioScaffolds Combine Synthetic and Biologic Materials For Soft Tissue Repair

Dr. Michael Sawyer

Michael Sawyer, MD, FACS
General Surgeon
Comanche County Memorial Hospital

MedicalResearch.com: What is the background for this study?

 

Response: Repair of complex incisional hernias is a challenging surgical task. Abdominal wall surgeons are utilizing advanced abdominal wall reconstruction (AWR) techniques including myofascial advancement flap creation with reinforcement by biologic or synthetic prostheses with greater frequency.

Numerous synthetic or biologic surgical mesh products are currently available to reinforce these soft tissue repairs. Each type of biologic or synthetic material has its own advantages and limitations.

OviTex Reinforced BioScaffolds (RBSs) are unique in that they interweave polymer in a custom “lock-stitch” pattern through layers of biologic tissue in an embroidered construction, aiming to incorporate the salutary properties of both biologic and synthetic repair materials. The biologic material, derived from ovine rumen, has been optimized to minimize foreign body response and enables functional tissue remodeling. The polymer provides additional strength, along with improved handling and load‑sharing capability.

Editor in Chief, JAMA Surgery 

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: This study is a follow-up to our previous work that examined sex bias in surgical research. Previously, we examined sex bias in basic and translational science surgical research, as well as in clinical surgical research. We discovered previously that sex bias exists in basic and translational surgical research in the unequal inclusion of male and female research subjects.
In clinical research, we found sex bias in the degree of sex matching of included subjects, and in the frequency of sex-based reporting, analysis, and discussion of the data.

In this current work, we sought to understand the effect of author gender on sex bias in surgical research. In this work, we found that most authors are male, most authors work with other authors of the same gender, and sex bias is prevalent regardless of author gender. Most importantly, we found that sex inclusive research receives more citations after publication compared to sex-biased research.  Continue reading

Ankle Fracture: Close Casting Can Be Alternative To Surgery For Older Patients

David Keene DPhil
NIHR Postdoctoral Research Fellow
NDORMS Research Fellow in Trauma Rehabilitation
Critical Care, Trauma and Rehabilitation Trials Group
Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences
University of Oxford 

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Our clinical trial comparing close contact casting to the usual internal fixation surgery for unstable ankle fractures in older adults found that ankle function at six months was equivalent. There was more abnormal healing of the fracture seen on radiographs (malunion) in the casting group (15 percent, compared to 3 percent for surgery) so we aimed to investigate the ankle function outcomes in the longer term. We found that equivalence in ankle function between initial close contact casting and surgery was maintained at three years. 

MedicalResearch.com: What should readers take away from your report?

Response: Our findings indicate that close contact casting is an appropriate alternative treatment to surgery for older people with an unstable ankle fracture. These longer-term outcomes will help surgeons and patients to make informed decisions about the right course of action for them. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: Future research will explore if there are certain types of older patients that do well after close contact casting or surgery. 

MedicalResearch.com: Is there anything else you would like to add?

Response: It is worth highlighting that the initial close contact casting was applied in the operating room under anesthesia.

There were no conflicts of interest.

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Rates of total shoulder arthroplasty are increasing, especially with an aging population.  Blood loss requiring transfusion is less common than in total hip or knee replacements but still required in some patients.  Tranexamic acid (TXA) is increasingly used to reduce blood loss in lower extremity arthroplasty but limited data exists for its effectiveness and safety in patients undergoing shoulder arthroplasty. We aimed to utilize national data to assess frequency of use and effectiveness of TXA in shoulder arthroplasty patients.

While utilization of TXA has become very common in total hip and knee arthroplasty, TXA is still used in less than 50% of patients undergoing shoulder arthroplasty as of 2016.  TXA use was associated with a 36% decrease in transfusion risk and a 35% decreased risk for combined complications. Moreover, TXA use was associated with 6.2% shorter hospital stay.

MedicalResearch.com: What is the background for this study?

Response: Approximately 35,000 transcatheter aortic valve replacement (TAVR) procedures are now performed annually in the United States (US). TAVR is usually performed as an elective procedure in hemodynamically stable patients. Approximately 1 in 5 hospitalizations for severe aortic stenosis (AS) are emergent with acute decompensation. Balloon aortic valvuloplasty (BAV) is a therapeutic option in patients with acute decompensated AS; however, long-term survival after BAV remains poor with a high incidence of valvular re-stenosis. Data on the outcomes of urgent/emergent TAVR as a rescue therapy in patients with acute decompensated severe AS are extremely limited.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Over 20 million Americans undergo a surgical procedure each year with a price tag over $1 trillion.  The operating room (OR) is a particularly resource dense environment, yet little is known about the actual costs of running an OR.  Most previous efforts focusing on OR costs have come from single-site studies with little detail about the drivers of OR costs.

Using financial statements from all California hospitals we estimated that the average cost to the hospital for one minute of OR time was between $36 and $37. Perhaps more notable was the composition of these costs.  Almost two-thirds ($20-21) was attributable to “direct costs” – those generated by the OR itself – including $14 for the wages and benefits of staff, $2.50-3.50 for surgical supplies, and $3 for “other” costs such as equipment repair and depreciation. Interestingly, the remainder ($14-16) was dedicated to “indirect costs” such as the costs associated with hospital security and parking.  While these indirect costs are necessary for a hospital to run, they are not under the purview of the operating room.

Finally, we also learned that OR costs have increased quickly over the past 10 years – faster than other sectors of healthcare as well as the rest of the economy. Continue reading

What is the background for this announcement?

Response: We’re proud and excited to make Rebinyn® (Coagulation Factor IX (Recombinant), GlycoPEGylated) available as a new extended half-life treatment for hemophilia B management.

Rebinyn® is an injectable medicine used to treat and control bleeding in adults and children with hemophilia B. It can be used to treat bleeds when they occur and to manage bleeding during surgery. Rebinyn® is not used for routine prophylaxis or for immune tolerance induction in patients with hemophilia B.
