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.

Response: Buprenorphine has been proven effective in treating opioid use disorder. However, the high cost of buprenorphine and the limited prescribing capacity may restrict access to this effective medication-assisted treatment (MAT) for opioid use disorder.
We found a 70% increase in Medicaid-covered buprenorphine prescriptions and a 50% increase in buprenorphine spending associated with the implementation of Medicaid expansions in 26 states during 2014. Physician prescribing capacity was also associated with increased buprenorphine prescriptions and spending.

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.

MedicalResearch.com: What is the background for this study?
Response: No doubt sports plays a huge role in the United States and all over world with millions of young people between the ages 6 and 18 participating in an organized sport on a regular basis.
Over the past decade, there has been a tremendous focus on youth single sport specialization (SSS), with pressure from coaches, parents and the athletes themselves to participate in one sport year round. Many participants, coaches and parents believe that early specialization may allow the young athlete to become better and progress more quickly in their sport, perhaps allowing them a greater chance of becoming a professional athlete. This drive toward early specialization has been fueled by popular icons i.e. Tiger Woods (golf) and Lionel “Leo” Messi (soccer) as well as by media hits such as Friday Night Tykes (young football players) and The Short Game (7-year old golfers). The pop-psych writer, Malcolm Gladwell, whose The 10,000 Hour Rule (in his book Outliers) holds that 10,000 hours of "deliberate practice" are needed to become world-class in any field may have also encouraged the specialization trend.
There is little doubt that youth sports may encourage a lifelong interest in a healthy lifestyle as well as improved self-esteem and social relationships. The flip side is that extreme training and singular focus on a sport can lead to stress on the developing musculo-skeletal system, a pressure to succeed at all costs, reduced fun, burnout and sometimes social isolation.
The dilemma we are beginning to scratch the surface of is does single sport specialization enhance the likelihood of getting to an elite level and does it increase the risk of injury? There is a growing sense in the medical community that SSS raises injury risk without enhancing progression to a higher level.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: There was a gap in our knowledge about what the average lay person thought about the impact of a facelift. We had information about what experts in the field like Dr. Swail thought, and some about what patients themselves thought, but nothing about lay people.
Patients who choose to have a facelift are typically concerned about the opinions of:
1) Themselves when they look in the mirror, and
2) Laypeople they encounter socially in society.
Our study showed for the first time that laypeople find people who have had a facelift to appear more attractive, more youthful, healthier and more successful than they were before their facelift.

Response: For decades, surgeons performing hip replacements have placed the acetabular component adjacent to the pelvis in a “safe zone” which has been shown to reduce dislocation risk. However, beginning in residency, I would notice that several of my patients with spinal deformities or lumbar fusions, would experience dislocations despite the safe zone placement of these implants. Our initial research demonstrated that there was an increased dislocation risk in patients with lumbar fusions, particularly if they underwent spinal realignment. We investigated this phenomenon further by retrospectively reviewing 107 patients who met the criteria for sagittal spinal deformity, including 139 hip replacements collectively.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Prostate cancer is a very common malignancy which is frequently treated with external beam radiotherapy. A typical standard treatment course can extend over 7.5-8.5 weeks.
The introduction of high-precision radiotherapy treatment techniques provided the opportunity to compress treatment courses by delivering fewer, but more intensive daily treatments. The concerns with giving fewer and larger daily treatments (hypofractionation) is that toxicity may increase and that cancer control may become worse.
This international randomized trial enrolled 1206 men with intermediate risk prostate cancer and compared a standard 8 week course of external beam radiation treatment with a novel hypofractionated treatment course that was given over 4 weeks. Cancer control as measured by PSA control and clinical evidence of failure, bowel and bladder toxicity and quality of life were compared.
At a median follow-up of 6 years the hypofractionated regimen was found to be non-inferior to the standard regimen for cancer control. There was no difference early or late bladder toxicity between the two treatments. There was slightly worse early bowel toxicity during and immediately after treatment with the hypofractionated regimen, but there was actually slightly less long-term bowel toxicity with this same regimen.

Response: Our study reviewed medical literature to examine the question of whether minor teens should be treated differently from older women with regard to a future over the counter oral contraceptive product. Our analysis found that oral contraceptive pills are safe and effective for teens and there is no scientific rationale to restrict access to a future oral contraceptive pill based on age.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Prior work has demonstrated racial and socioeconomic disparities in breast cancer diagnosis, treatment, and outcomes. As the oncology field has progressed over the past decade, the use of genetic testing to guide treatment decisions is one of the most exciting new developments.
Our team was concerned that these new gene tests, which can offer important benefits, may have the potential to exacerbate disparities further. That is, if there is unequal access to gene testing among patients for whom it is recommended, then our progress against cancer will not be equitably shared among people of all races and ethnicities.

Response: The association between exposure to testosterone replacement therapy and prostate cancer risk is controversial. The purpose of our study was to examine this issue using national registries from Sweden, with complete records on prescription medications and prostate cancer diagnoses. Overall, we found no association between testosterone use and overall prostate cancer risk. There was an early increase in favorable cancers which is likely due to a detection bias, but long-term users actually had a significantly reduced risk of aggressive disease.

Response: The Chinese Great Leap Forward Famine in 1959-1961 is the largest famine in human history. Earlier studies have reported that overweight, type 2 diabetes, hyperglycemia, the metabolic syndrome and schizophrenia were more common among adults who were exposed to the famine. Our re-analysis of all previous studies shows no increases in diabetes, high blood pressure and other chronic conditions among famine births except for schizophrenia.

MedicalResearch.com: What is the background for this study?
Response: I decided to conduct this study after observing a few cases of severe acute kidney injury (AKI) in children hospitalized with diabetic ketoacidosis (DKA) (with two patients requiring dialysis) while on call in the 18 months prior to initiating the study. While caring for these patients, I scanned the literature and realized that aside from 2 published case reports, there had been no large-scale systematic studies assessing AKI in children with DKA. It immediately became apparent to me that managing patients with AKI and DKA was more challenging. On presentation to hospital, many of these children with DKA present quite volume depleted but fluid management is conservative because of the risk for cerebral edema.
One of the most important management strategies for acute kidney injury in patients with DKA is early detection and correcting volume depletion in a timely manner to prevent further injury. I discussed my observations and these clinical cases with pediatric nephrologist and co-investigator Dr. Cherry Mammen, a pediatric AKI expert, and he confirmed my initial literature review findings. Thus, we decided to conduct this study to better understand the scope of the problem and any associated risk factors.

Response: Concussions remains a significant problem in youth sports. The recent enactment of Traumatic brain injury laws have certainly heightened awareness regarding this problem. Our study looked at publicly available data regarding diagnosis of concussion in high school athletes. We found that females are more likely to be diagnosed with a concussion than males. We also concluded that girl soccer players and boys football players are at highest risk for a diagnosis of concussion. Since the neck meant of the Traumatic brain injury state laws, the diagnosis of concussion in this patient group increased significantly past decade.

Response: Skin cancer is the most common form of cancer in the United States. Results from the School Health Policies and Practices Study found that in 2014, most schools lacked practices that could protect children and adolescents from sun exposure while at school. Positive attitudes and beliefs about sun safety behavior, which would make such behavior more likely, can be promoted and supported by school system policies and practices.

Response: Previous research has found that daily administration of vitamin D is important for maintaining bone homeostasis. There has been an increased interest among the orthopaedic community regarding vitamin D supplementation and patient outcomes following fractures. Using data from the FAITH trial (NCT01908751), a multicenter randomized controlled trial that compared cancellous screws versus sliding hip screws in patients over the age of 50 with femoral neck fractures, we:
1) determined the proportion of patients consistently taking vitamin D following hip fracture surgery and
2) determined if supplementation was associated with improved health related quality of life and reduced re-operation.
Patients enrolled in the FAITH trial were recruited from 81 clinical sites in 8 countries over a 6-year span. We asked a subset of them about vitamin D supplementation and categorized them as consistent users, inconsistent users, or non-users.
The final analysis included 573 patients and we found that a surprisingly low proportion of elderly hip fracture patients are consistently taking vitamin D (18.7% of patients reported never taking vitamin D, 35.6% reported inconsistent use, and 45.7% reported consistent use). We also found that vitamin D was associated with a statistically (p=0.033), but not clinically, significant improvement in health-related quality of life following a hip fracture. Lastly, supplementation was discovered to not be associated with reduced re-operation (p=0.386).

Response: Depression and mood disorders are common comorbidities in patients undergoing total hip and total knee arthroplasty. Based on previous research, there is evidence to suggest presence of depression in arthroplasty patients is associated with worse functional and clinical outcomes, such as complications, readmissions and mortality. Although the mechanisms are poorly understood, it is important to identify strategies to effectively manage perioperative depression in an effort to improve arthroplasty outcomes. One potential strategy is effective medical treatment of underlying depression which can potentially improve depression symptoms, thereby surgical outcomes.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: There have been large increases in opioid-related adverse events over the past decade. The goal of our study was to examine the extent to which these increases may have been driven by combined use of opioids and benzodiazepines, a combination that is known to be potentially risky. Overall, we found that the combined use of opioids and benzodiazepines nearly doubled (80% increase) between 2001 and 2013, and that opioid users who also used benzodiazepines were at a higher risk of an opioid-related adverse event. Indeed, our results suggest eliminating the combined use of opioids and benzodiazepines could have reduced the population risk of an opioid-related adverse event by 15%.

MedicalResearch.com: What is the background for this study?
Response: Environmental chemicals have long been discussed to contribute to the exacerbation or even the development of allergic diseases. In our study we were particularly interested in the effect of tobacco smoke exposure, which is the main source for indoor benzene exposure, on regulatory T cell (Treg) function and its relation to the development of childhood atopic dermatitis (AD). Tregs play a critical in controlling T effector cell activity by avoiding overexpression. A deficiency in this T cell subset increases the risk for allergic inflammation.
We have previously described that exposure to tobacco smoke during pregnancy can decrease the number of regulatory T cells (Treg) in the cord blood and predispose the child to the development of AD (1). In this subsequent study we were interested in the underlying mechanism involved.
Benzene itself is not considered to be toxic, however its metabolization leads to the formation of highly reactive molecules. In humans for example the metabolite 1,4-benzochinone (1,4-BQ) can be found in the blood as a consequence of benzene exposure.
To further assess the effect of benzene on Treg and the development of AD we combined in vitro studies, evaluating the impact of 1,4-BQ on human expanded Treg, with data from our prospective mother-child cohort LINA. The LINA study, recruited in Leipzig, Germany, is a longitudinal evaluation of mother-child pairs with respect to lifestyle and environmental factors that might contribute to disease development in the child. Based on this deeply phenotyped cohort we were able to translate our in vitro findings to the in vivo scenario.

Response: The presented study is a continuation of our interest in the role of stress and the possible causes of atrial fibrillation. We published a study that showed that spousal bereavement were followed by a transiently increased risk of new onset of atrial fibrillation. With spousal bereavement being one of the most stressful life-event, we wanted to know whether minor and differentiated stress exposures had an effect as well. Therefore we used register based data on perceived stress as a new measure of exposure.

MedicalResearch.com: What is the background for this study?
Response: A lot of previous research has identified genotypes that increase sensitivity to context. Much of this research, however, looks at particular aspects of health and is not able to address the methodological challenges of investigating gene-environment interactions. To gain a better sense of the potential outcomes that may be susceptible to gene-environment interactions, I examine financial standing in young adulthood. Testing this type of interaction is challenging because genotype and social environment are not randomly distributed throughout the population. Given this non-random distribution, unobserved confounders (such as parental behaviors, education, ethnicity, or social capital) could influence both parent and child financial standing.
