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

Response: The inspiration for this study comes from my personal experience as a medical student on clinical rotations. Despite having been a victim of a medical error while growing up myself, I found it extraordinarily difficult to admit to even some of my smallest errors to my patients and team. Perplexed by the psychological barriers that impeded error disclosure, I began to discuss this subject with my advisory Dean and mentor, Dr. Neha Vapiwala. We wanted to analyze the topic more robustly through an academic lens and researched cognitive biases that must be overcome in order to facilitate effective disclosure of error, and began to think about potential ways to implement these strategies into the medical school curriculum with the help of the director of the Standardized Patient program at the Perelman School of Medicine, Denise LaMarra.

We ultimately contend that any educational strategy that aims to truly address and improve error disclosure must target the cognitive roots of this paradigm. And at this point in time, simulation-based learning seems to be the most direct way to do so, but also remain hopeful that emerging technologies such as virtual and augmented reality may offer ways for students as well as staff to rehearse difficult patient encounters and improve.

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

Response: Previous studies showed an association between genetic variants in the APOL1 gene and kidney disease development, but it has not been confidently shown that this genetic variant is actually causal for kidney disease. For this reason we developed a mouse model that recapitulates the human phenotype.

Weight Shaming Can Cause Physical As Well As Mental Harm

MedicalResearch.com Interview with:
Rebecca L. Pearl PhD
Department of Psychiatry, Center for Weight and Eating Disorders
Perelman School of Medicine
University of Pennsylvania, Philadelphia, Pennsylvania

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

Response: Weight bias is a pervasive form of prejudice that leads to weight-based discrimination, bullying, and the overall stigmatization of obesity. Some individuals with obesity may internalize weight bias by applying negative weight stereotypes to themselves and “self-stigmatizing.” Exposure to weight bias and stigma increases risk for poor obesity-related health (in part by increasing physiological stress), but little is known about the relationship between weight bias internalization and risk for cardiovascular and metabolic diseases.

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

Response: We have been studying trends in health compromising behaviors in popular films that were released since 1950, and in 2013 we reported that films rated PG-13 had just passed the rate of portrayed gun violence shown in popular R-rated films in 2012. In this report, we updated the trends in gun violence through 2015 and found that the trend has continued. In addition, we noted the strong contribution to this trend of films with comic book heroes whose heavy use of guns omits the harmful and otherwise realistic consequences of blood and suffering.

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

Response: Bundled payments pay a fixed price for an episode of services that starts at hospital admission (in this case for joint replacement surgery) and extends 30-90 days post discharge (30 days in this study). This includes physician fees, other provider services (e.g. physical therapy), and additional acute hospital care (hospital admissions) in that 30 day window.

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

Response: Each year the U.S. Army Family Advocacy program (FAP) investigates between 6000 to 9000 reports of alleged abuse or neglect involving children of Army service members.   In approximately 48% of reported cases FAP determines a child was a victim of maltreatment, substantiates the report, and collaborates with local civilian child protection service (CPS) agencies in providing services and ensuring safety. Thus, FAP plays a key role in supporting Army families and protecting children.  But FAP can only investigate and respond to cases of child abuse and neglect about which they are aware.

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

• Allogeneic hematopoietic cell transplant (HCT) recipients with steroid-refractory gastrointestinal acute graft-versus-host disease (GI-GVHD) have poor outcomes.
• There is no consensus for optimal treatment of these patients.
• We retrospectively evaluated the efficacy of tocilizumab, an interleukin-6 receptor monoclonal antibody, for the treatment of steroid-refractory GI-GVHD.
• 10/11 (91%) patients achieved a complete response after a median time of 11 days (range, 2 – 18) from tocilizumab initiation.
• The median time to response onset, defined as improvement in GVHD stage by at least 1, was 1 day (range, 1 – 6).
• At a median follow-up of 3 months (range, 1.1 – 12.8) from tocilizumab initiation, 8 of 11 patients are alive and free of the their underlying hematologic malignancy.
• No associations between serum levels of IL-6 and tocilizumab response could be identified.

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

Response: The passive administration of monoclonal antibodies has revolutionized many fields of medicine. Anti-HIV monoclonal antibodies are being explored as components of novel therapeutic and curative strategies, as they can both neutralize free virus and kill virus-infected cells. We sought to determine whether passive administration of an anti-HIV monoclonal antibody, VRC01, to chronically HIV-infected individuals on antiretroviral medications (ART) would be safe and well tolerated and could delay virus rebound after discontinuation of their ART.

Biomarker NLR Found Not Predictive of Bladder Cancer Survival

MedicalResearch.com Interview with:

Eric Ojerholm, MD Resident, Radiation Oncology Hospital of the University of Pennsylvania

Dr. Eric Ojerholm

Hospital of the University of Pennsylvania

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

Response: Multiple studies reported that a blood test —the neutrophil-to-lymphocyte ratio (NLR)—might be a helpful biomarker for bladder cancer patients. If this were true, NLR would be very appealing because it is inexpensive and readily available. However, previous studies had several methodological limitations.

MedicalResearch.com: What did you do in this study

Response: We therefore put NLR to the test by performing a rigorous “category B” biomarker study—this is a study that uses prospectively collected biomarker data from a clinical trial. We used data from SWOG 8710, which was a phase III randomized trial that assessed surgery with or without chemotherapy for patients with muscle-invasive bladder cancer. We tested two questions.

First, could NLR tell us how long a bladder cancer patient would live after curative treatment?

Second, could NLR predict which patients would benefit from chemotherapy before surgery?

Androgen Deprivation For Prostate Cancer Linked to Dementia

MedicalResearch.com Interview with:
Kevin T. Nead, MD, MPhil

Resident, Radiation Oncology
Perelman School of Medicine
Hospital of the University of Pennsylvania.

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

Response: Androgen deprivation therapy is a primary treatment for prostate cancer and works by lowering testosterone levels. There is a strong body of research suggesting that low testosterone can negatively impact neurovascular health and function. We were therefore interested in whether androgen deprivation therapy is associated with dementia through an adverse impact on underlying neurovascular function.
