Dr. Constance Brinckerhoff Professor of Medicine Professor of Biochemistry Geisel School of Medicine at DartmouthMedicalResearch.com Interview with: Dr. Constance Brinckerhoff Professor of Medicine Professor of Biochemistry Geisel School of Medicine at Dartmouth Medical Research: What are the main findings of the study? Dr. Brinckerhoff: The genetic mutation BRAFV600E , frequently found in metastatic melanoma, not only secretes a protein that promotes the growth of melanoma tumor cells, but can also modify the network of normal cells around the tumor to support the disease’s progression. Targeting this mutation with Vemurafenib reduces this interaction, and suggests possible new treatment options for melanoma therapy. (more…)

Renata Afi Rawlings-Goss, Ph.D. Postdoctoral Fellow Tishkoff Lab, University of PennsylvaniaMedicalResearch.com Interview with: Renata Afi Rawlings-Goss, Ph.D. Postdoctoral Fellow Tishkoff Lab, University of Pennsylvania   Medical Research: What are the main findings of the study? Dr. Rawlings-Goss: We found genetic mutations in key gene regulators that have been linked to ethnic disparities in cancer. Our investigation identified more than 30 previously undescribed mutations in important regulatory molecules called microRNAs. Individual microRNA molecules can regulate large numbers of genes in some cases over 6000 genes at once. Therefore, mutations in these genes have been linked to numerous diseases. By and large, however, microRNA mutations have not been studied in people of diverse ethnic backgrounds. (more…)

Mary G. Lynch, MD Professor of Ophthalmology Atlanta Veterans Affairs Medical Center Decatur, Georgia. Department of Ophthalmology, Emory University School of Medicine, Atlanta, GeorgiaMedicalResearch.com Interview with: Mary G. Lynch, MD Professor of Ophthalmology Atlanta Veterans Affairs Medical Center Decatur, Georgia. Department of Ophthalmology, Emory University School of Medicine,  Atlanta, Georgia Medical Research: What are the main findings of the study? Dr. Lynch:
  • Since 2006, the VA has been systematically using teleretinal screening of patients with diabetes to screen for retinopathy in the Primary Care Clinics. Under this program, 90% of veterans with diabetes are evaluated on a regular basis. A number of patients who are screened have findings that warrant a face-to-face ophthalmic exam. No information exists on the effect of such a program on medical center resources.
  • 1,935 patients  underwent teleretinal screening through the Atlanta VA over a 6 month period.  We reviewed the charts of the 465 (24%) of the patients who were referred for a face to face exam in the Eye Clinic.
  • Data was collected for these patients to determine the reasons for referral, the accuracy of the teleretinal interpretation, the resources needed in the Eye Clinic of the Medical Center to evaluate and care for the referred patients over a two year period and possible barriers to patient care.
  • Of the 465 patients referred for an exam, 260 (55.9%) actually came in for an exam. Community notes were available for an additional 66 patients. Information was available for 326 (70.1%) of the referred patients.
  • The most common referring diagnoses were nonmacular diabetic retinopathy (43.2% of referrals), nerve related issues (30.8%), lens or media opacity (19.1%), age-related macular degeneration (12.9%) and diabetic macular edema (5.6%).
  • 16.9% of the referred patients had 2 or more concurrent problems that put them at high risk for visual loss.
  • The percentage agreement between teleretinal screening and the ophthalmic exam was high: 90.4%. Overall sensitivity was 73.6%. The detection of diabetic macular edema had the lowest sensitivity.
  • A visually significant condition was detected for the first time through teleretinal screening for 142 of the patients examined (43.6%).
  • The resource burden to care for referred patients was substantial.
  • 36% of patients required 3 or more visits over the ensuing 2 year period.
  • The treatment of diabetic macular edema had the highest resource use involving on average 5 clinic visits, 6 diagnostic procedures and 2 surgical procedures
  • The most common non-refractive diagnostic procedures were visual fields and optical coherence tomography.
  • The average cost to care for the referred patients (in Medicare dollars) in work RVUs alone was approximately $1,000 per patient. The cost to care for a patient with diabetic macular edema was $2673.36.

MedicalResearch.com Interview with: Patrick Corrigan Psy.D. Distinguished Professor of Psychology Illinois Institute of Technology PI: National Consortium on Stigma and Empowerment www.NCSE1.orgPatrick Corrigan Psy.D. Distinguished Professor of Psychology Illinois Institute of Technology PI: National Consortium on Stigma and Empowerment www.NCSE1.org Medical Research:  What are the main findings of this review? Dr. Corrigan: People with serious mental illness often do not seek out services, or drop out early, when in need. Stigma is a major reason for why this happens. Stigma refers to the stereotypes about a group that undermine status and lead to discrimination. Discrimination refers to the behaviors that block the opportunities of group members. Some employers do not hire people with mental illness, some landlords do not rent to them, and some primary care practitioners offer a substandard of care. Stereotypes and discrimination undermine engagement in mental health services in three ways (Corrigan, 2005): Label Avoidance: In order to escape the pernicious effects of stigma, people avoid settings where they are labeled mentally ill; for example, people coming out of a psychiatrist’s office may be perceived as “nuts.” Self-Stigma: Some people who internalize stereotypes suffer diminished self-esteem and self-efficacy leading to the “why try” effect. “Why should I try to get a job? Someone like me is not worthy.” “Why should I try to get mental health treatment? I am not able to benefit from it.” Structural Stigma: Stereotypes and discrimination become institutionalized in the laws and practices of government and business. For example, insurance coverage for mental health services was significantly below that for most other conditions.   (more…)

Yves A. Lussier, MD, Fellow ACMI Professor of Medicine Associate Vice President for Health Sciences (Chief Knowledge Officer) The University of ArizonaMedicalResearch.com Interview with: Yves A. Lussier, MD, Fellow ACMI Professor of Medicine Associate Vice President for Health Sciences (Chief Knowledge Officer) The University of Arizona Medical Research: What are the main findings of the study? Dr. Lussier:  The main finding is that reporting patient safety using ICD-10-CM coding schema rather than ICD-9-CM will change the reported percentage of adverse events reported for half the specific "patient safety indicators" (PSIs), even with a true unaltered frequency of reported events in the medical center. For some patient safety indicators, the reported frequency will appear to increase substantially and for others, it will appear to decrease.  The latter is particularly  worrisome as it may erroneously appease administrators and prospective clients (patients) as their apparent trend is improving, while their institution may inadvertently be under-reporting adverse events.

Dr. Heather Stuckey D.Ed Department of Medicine Pennsylvania State University College of Medicine, Hershey, PAMedicalResearch.com: Interview with: Dr. Heather Stuckey D.Ed Department of Medicine Pennsylvania State University College of Medicine, Hershey, PA MedicalResearch: What are the main findings of this study? Dr. Stuckey: The main findings were that people with diabetes had both negative psychosocial and positive (adaptive) ways of coping with diabetes. Negative themes included:  1) Anxiety/fear, worry about hypoglycemia and complications of diabetes, depression and negative moods/hopelessness and 2) Discrimination at work and public misunderstanding about diabetes. Two psychosocial themes demonstrated adaptive ways of coping with diabetes: 1) Having a positive outlook and sense of resilience in the midst of having diabetes and 2) Receiving psychosocial support through caring and compassionate family, friends, healthcare professionals and other people with diabetes. Most diabetes social sciences research focuses on only the negative aspects of having diabetes.  Although this paper discussed negative aspects, it also focused on the adaptive, or positive, ways in which people with diabetes viewed their disease.  "We found that although these negative experiences with diabetes exist, people also held on to the positive aspects.  Some said diabetes made their lives a little richer because they ate healthier foods, or they were able to connect with their family more to overcome challenges. It gave them a better appreciation of what they have.  The discrimination at work and from society was a finding that was unexpected, but was evident throughout both the quantitative and qualitative data.

Curhan, MD, ScM Channing Division of Network Medicine Department of Internal Medicine Brigham and Women's Hospital Harvard Medical School Boston, MA 02115 Medical Research: What are the main findings of the study? Dr. Curhan: We followed more than 65,000 women who were participants in the Nurses’ Health Study II over 18 years and found that eating 2 or more servings of fish per week was associated with a lower risk of hearing loss. For example, after adjusting for potential confounders in multivariable analyses, in comparison with women who rarely or never ate fish, women who consumed 2 or more servings of fish per week had a 20% lower risk of hearing loss. Eating any type of fish (tuna, dark fish, light fish or shellfish) tended to be associated with lower risk. Also, we found that higher intake of long-chain omega-3 polyunsaturated fatty acids (PUFAs) was inversely associated with risk. For example, in comparison with women with the lowest intake, women with the highest intake of long-chain omega-3 PUFAs had a 22% lower risk of hearing loss. (more…)

MedicalResearch.com Interview with: Eero Haapala, MSc in Exercise Medicine, BASc PhD student University of Eastern Finland,School of Medicine Institute of Biomedicine, Physiology Kuopio, Finland Medical Research: What are the main findings of the study? Answer: Our study is one of the first studies to investigate the different types of physical activity and sedentary behavior with academic achievement in children. Our main finding was that children who were more physically active during school recess were better readers in Grades 1-3 than less active children. We also found a direct relationship between physically active school transportation, which was mainly walking and cycling, and reading skills in boys. These findings suggest that particularly physical activity within a school day benefits academic achievement and that physical activity benefit academic achievement more in boys than in girls 6-8 years of age.

MedicalResearch.com Interview with: Rena Zuo, BA MD Candidate at Duke University School of Medicine and Edward W. Cowen, MD, MHSc Senior Clinician Head, Dermatology Consultation Service Dermatology Branch Center for Cancer Research National Cancer Institute National Institutes of Health MedicalResearch: What are the main findings of the study?
 Answer: Chronic graft-vs-host disease (cGVHD) is a debilitating multisystem disease that occurs in patients receiving allogeneic hematopoietic stem cell transplantations as treatment for hematologic disorders. Although the diverse clinical presentations of cGVHD frequently mimic other autoimmune diseases such as Sjögren syndrome and systemic sclerosis, and low-titer antibodies are commonly found in patients with cGVHD, the exact pathogenesis and role of autoimmunity in cGVHD are incompletely understood. Our study is the first to characterize and identify risk factors associated with the development of two uncommon autoimmune phenomena, specifically alopecia areata and vitiligo, in the setting of cGVHD. Laboratory markers, including 11 antibodies, transplant-related factors, and other cGVHD systemic manifestations were analyzed. Several particularly interesting results were found:
  1. Among 282 patients with cGVHD, 15 demonstrated vitiligo (14 of 282; 4.9%) and/or alopecia areata (2 of 282; 0.7%).
  2. Female donor and female donor to male recipient sex mismatch, in particular, are significantly associated with the development of vitiligo and/or alopecia areata.
  3. Positive anti-cardiolipin (ACA) IgG was also significantly associated with development of vitiligo and/or alopecia areata.

MedicalResearch.com Interview With: Ruth C. E. Hughes Department of Obstetrics and Gynecology University of Otago, Christchurch Women’s Hospital Christchurch, New Zealand Medical Research: What are the main findings of the study? Dr. Hughes: The increasing prevalence of undiagnosed type 2 diabetes in women of childbearing age was the main driver behind our study.  In clinical practice, we were finding that women with probable undiagnosed diabetes (and pre-diabetes) had already started developing pregnancy complications at the time they were diagnosed with gestational diabetes diagnosis in the late second trimester. It seemed logical to try to identify them in early pregnancy, with the idea that they might benefit from earlier intervention.  We thus explored the usefulness of first trimester HbA1c measurements to identify women with unrecognised pre-existing diabetes. In our study, an HbA1c of 5.9% (41mmol/mol) was the optimal screening threshold for diabetes in early pregnancy.  We found that a threshold of 6.5% (48mmol/mol), which is endorsed by the World Health Organization and American Diabetes Association for diagnosing diabetes in pregnancy, would miss almost 50% of women with probable pre-existing diabetes.  Of great relevance, women with an early HbA1c of 5.9%-6.4% (41-46mmol/mol) had poorer pregnancy outcomes than those with an HbA1c <5.9% (<41mmol/mol), with a 2.5-3 fold higher relative risk of major congenital anomaly, preeclampsia, shoulder dystocia, and perinatal death.  These women were also more likely to deliver before 37 weeks gestation.

Dr. Weinmann: The main findings included:
  • Mandatory influenza immunization for health care workers without allowing optional opt-out (and only allowing for documented medical or religious exemption) successfully raised our immunization uptake among all our employees to over 99% sustainable for the last 2 years which we consider a very important patient safety initiative.
  • Less than 2% of workers met a medical or religious exemption.
  • A prior optional opt out with mask wearing was problematic for staff and patients and did not reach our goal of close to 100% immunization uptake.

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…)

MedicalResearch.com Interview with: Edmund Silins PhD, Research Fellow National Drug and Alcohol Research Centre UNSW Medicine University of New South Wales Sydney  Australia Medical Research: What are the main findings of the study? Dr. Silins: There were three particularly interesting aspects to the findings.
  • Firstly, we found clear and consistent associations between adolescent cannabis use and the young adult outcomes investigated.
  • Secondly, there was evidence of a dose-response effect such that the more frequently adolescents used cannabis the more likely they were to experience harms later in life.
  • Thirdly, for most outcomes, these associations remained even after taking into account a wide range of other factors which might potentially explain them.
The adverse effects were greatest for daily cannabis users. Specifically, adolescents who were daily cannabis users were, by the age of 25, more than 60% less likely to complete high school or obtain a university degree, seven times more likely to have attempted suicide, 18 times more likely to have been cannabis dependent, and eight times more likely to have used other illicit drugs, than adolescents who had never used the drug.

MedicalResearch.com Interview with: Dr. Giulia Scioscia Coauthor of this study with the Prof. Carpagnano University of Foggia. Medical Research: What are the main findings of this study? Dr. Scioscia: The principal and newest findings of our study are:
  • Airways inflammation and neoangionesis are critical component of the lung cancer pathogenesis and they contribute to the regulation of airways temperature. They cause a regional hyperthermia in the lung lesion.
  • The exhaled Breath temperature has been proven to be the expression of the airways temperature and for this reason of their inflammation and neoangionesis.
  • For the first time we have measured this hyperthermia in lung cancer patients with the xhalo. The patient with diagnosis of tumor shows an higher temperature than in healthy ones and this values correlate with cigarette smoking and tumor progression.

Crandall, MD, MS Professor of Medicine David Geffen School of Medicine at University of California, Los Angeles   Medical Research: What are the main findings of the study? Dr. Crandall: 1.        We found high-strength evidence that several medications decrease fracture risk when used by persons with bone density in the osteoporotic range and/or with pre-existing hip or vertebral fracture.  While many of the medications (alendronate, risedronate, zoledronic acid, ibandronate, denosumab, teriparatide, and raloxifene) reduce vertebral fractures, a reduction in the risk of hip fracture is not demonstrated for all of the medications.  In particular, hip fracture reduction is only demonstrated for alendronate, risedronate, zoledronic acid, and denosumab.  Unfortunately, due to a lack of head-to-head trials, the comparative effectiveness of the medications is unclear. 2.       The adverse effects of the medications vary.  For example, raloxifene is associated with an increased risk of thromboembolic events, whereas denosumab and the bisphosphonate medications have been associated with increased risk of osteonecrosis of the jaw and atypical subtrochanteric femoral fractures.
