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

Response: The rate of cesarean delivery has increased dramatically over the last 30 years. And in an effort to curb the rising trend in caesarean delivery, The American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine have recently advocated for increased use of operative vaginal delivery (forceps/vacuum delivery) as a strategy to reduce the cesarean delivery rate. The evaluation of approaches to achieve this end are underway and the current discourse surrounding operative vaginal delivery centers on methods to promote these important skills. But, the truth is, we don’t yet fully understand the balance of risks and benefits to mothers and their babies following operative vaginal delivery compared with caesarean delivery.

The preferred choice given these two options relies heavily on how far the baby’s head has descended in the birth canal. If the baby’s head has descended far enough that it is visible and on the perineum, then the use of an instrument has clear advantage. However, when the fetal head is engaged in the maternal pelvis, but has not descended so far down the birth canal, the decision between these modes of delivery becomes much less clear. These deliveries are called midpelvic deliveries. And it’s an increase in these midpelvic deliveries that would have the most potential as a strategy to reduce the cesarean delivery rate, and as a result, it is these deliveries that we were interested in studying.

Operative vaginal deliveries are carried out in approximately 14% of all term births in Canada and those that occur when the baby is at midpelvic station account for over 20% of all operative vaginal deliveries. This translates to about 2-3% of all term, singleton deliveries in Canada or about 10,000 deliveries per year overall.

The literature on perinatal and maternal outcomes contrasting midpelvic operative vaginal delivery and caesarean delivery is based on studies undertaken 25 to 30 years ago that are no longer reflective of the current obstetric practice.  This was the impetus for our study. We reasoned that before we decide to encourage increased OVD we should first get a sense of the safety of such procedures compared to cesarean delivery as provided by contemporary maternity care providers.

Young Athletes Who Specialize In Single Sport May Raise Risk of Overuse Injury

MedicalResearch.com Interview with:
Jacqueline Pasulka, OMS II
Des Moines University College of Osteopathic Medicine , Des Moines , IA
Division of Pediatric Orthopaedic Surgery & Sports Medicine, Ann & Robert H. Lurie Children’s Hospital of Chicago , Chicago , IL

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

Response: In this study young athletes were recruited from both sports medicine and general practice clinics and were asked to complete surveys reporting on their sports participation, training patterns, and any sports-related injuries they had over the previous six months. We focused this study on the subset of athletes who met the criteria for being a single-sport specialized athlete based on their reported participation in only one sport and training for eight months or more during the year for that sport. Athletes participating in individual sports were more likely to be single-sport specialized than their team sport peers, and they also reported an earlier age at which they began specializing in their sport. Additionally, injury types differed among these two groups as single-sport specialized athletes in individual sport athletes had a greater proportion of overuse injuries, while single-sport specialized athletes in team sport athletes had a greater proportion of acute injuries.

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

Response: Bone fractures are one of the leading causes of disability and ill health especially among the ageing population and are a burden to health care systems. There is established evidence that calcium and vitamin D play an important role in bone health.

Magnesium is an essential trace element, being the second most abundant intracellular cation after potassium and the fourth most abundant cation in the body. It serves several important functions in the body, which include protein synthesis, nucleic acid synthesis, enzymatic reactions, and has also been shown to be cardio-protective. It is also an important component of bone, with majority (67 percent) of total body magnesium known to be found in the bone tissue. There have been suggestions from both human and animal experiments that magnesium may have a beneficial effect on bone health; however, its relationship with fractures is not very certain.

Radiation Exposure in the Pediatric Patient: What Every Orthopaedist Should Know

MedicalResearch.com Interview with:
Ayesha Rahman, MD

Chief Orthopaedic Surgery Resident
NYU Langone Medical Center.

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

Response: Children are more vulnerable and susceptible to lifetime adverse events from radiation exposure, caused by imaging . We reviewed literature and found certain pediatric orthopaedic patients are at greater risk for radiation exposure, namely those who have surgery for hip dysplasia, scoliosis, and leg length discrepancy, as they are among those most likely to undergo CT imaging. After reviewing all types of imaging studies performed in orthopedics and how much radiation is involved in each test, we developed several recommendations that pediatric orthopaedic surgeons should follow.

Among those recommendations are: utilize low-dose CT protocols or technology that uses less imaging (like EOS), limit CT scans of the spine and pelvis, know that female patients are more susceptible to adverse risk and plan accordingly, and follow the the “as low as reasonably achievable,”principle to limit exposure to parts of the body that are necessary for diagnosis.

Dr. Jonathan L. Silverberg MD PhD MPH Assistant Professor in Dermatology Medical Social Sciences and Preventive Medicine Northwestern University, Chicago, Illinois

Dr. Jonathan Silverberg

Response: Psoriasis is associated with a number of potential risk factors for developing osteoporosis and pathological fractures, including including low vitamin D, chronic inflammation, higher rates of cigarette smoking and systemic corticosteroid usage. We hypothesized that adults with psoriasis have higher rates of osteoporosis and pathological fractures.

We examined data from the 2002-2012 National Inpatient Sample, which contains a representative 20% sample of all hospitalizations in the United States. We found that psoriasis was associated with higher odds of osteopenia, osteoporosis, osteomalacia, ankylosing spondylitis, and pathological fractures. In particular, psoriasis was associated with vertebral, pelvic, femoral and tibial/fibular fractures. The associations between psoriasis and pathological fractures were more pronounced in women than men.

Dr. Hammoud

Dr. Sommer Hammoud

Dr. Sommer Hammoud MD
ABOS Board Certified Assistant Professor of Orthopedic Surgery
Thomas Jefferson University 

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

Response: The background for this exhibit stemmed from the growing problem of prescription opioid abuse in the United States.  As we saw this issue developing, we aimed to investigate the history behind this epidemic, what information we have now to fight it, and what information we need in the future to improve care our patients.

Our main findings for each of those aims are the following:

1) It would appear that a large push at the end of the last century led to a lower threshold to prescribe opiates in the effort to control pain, leading to the current opioid epidemic
2) Mulitmodal methods of pain control and the expanding skill of regional anesthesia can be used to help decrease narcotic use and thus limit exposure to narcotics, and
3) Future research needs to focus on the psychologic aspect of patients’ ability to manage pain and we should strive to be able to categorize patients in order to create an individualized pain management protocol which will most effectively manage pain.

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

Response: As bundled payment initiatives increase in order to contain health care costs, total shoulder arthroplasty (TSA) is a likely future target.

Understanding modifiable drivers of complications and unplanned readmission as well as identifying when such events occur will be critical for orthopedic surgeons and hospitals to improve outcomes and to make fixed-price payment models feasible for TSA.

Utilizing the American College of Surgeons National Surgical Quality Improvement Program we identified 5801 patients that underwent TSA with a 2.7% readmission rate and 2.5% severe adverse event rate. Patients with 3 or more risk factors were found to have a significantly increased risk of readmission and severe adverse events within the first two weeks postoperatively.

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

Response: Hospital for Special Surgery (HSS) researchers saw the need for a shorter, more patient friendly outcome survey for revision knee replacement surgery. This is an area where patient-reported outcomes data are essential to improving quality of care. In fact, knee replacement revisions, which are more complex and heterogeneous than primary knee surgery, are under-studied in this regard.

A commonly used knee replacement survey, the KOOS (Knee Injury and Osteoarthritis Outcome Score), is 42 questions and often leaves physicians with partial and unusable information secondary to patient burden and fatigue. Previously, researchers at HSS created the KOOS, JR, which is a shorter, 7-question survey that accurately measures “knee health”, meaning it reflects aspects of pain, symptom severity, and activities of daily living relevant and difficult for patients with knee arthritis. The current research presented at AAOS showed that the KOOS, JR can be extended to knee replacement revision patients and that it is a valid and efficient tool for assessing knee health in this challenging patient population.
