David Polsky, MD, PhD Alfred W. Kopf, MD, professor of Dermatologic Oncology Ronald O. Perelman Department of Dermatology NYU Langone Medical CenterMedicalResearch.com Interview with: David Polsky, MD, PhD Alfred W. Kopf, MD, professor of Dermatologic Oncology Ronald O. Perelman Department of Dermatology NYU Langone Medical Center Medical Research: What are the main findings of the study? Dr. Polsky: We utilized a multi-disciplinary approach including an analysis of socioeconomic factors to elucidate the evolution of attitudes and behaviors maximizing personal ultraviolet light exposure during the 20th century in the United States.  We then compared melanoma incidence rates from national cancer registries to estimated skin exposure and found that they rose in parallel. Though causation cannot be made in an analysis such as this one, this paper describes a historical context for the changing attitudes promoting increased UV exposure, and the rising incidence of melanoma throughout the past century.  It also provides a framework in which to consider public health and education measures that may ultimately help reverse melanoma incidence trends.

MedicalResearch.com Interview with: Jinjin Zheng Selin, MSc Unit of Nutritional Epidemiology Institute of Environmental Medicine Karolinska Institutet Stockholm Sweden Medical Research: What are the main findings of the study? Response: Our results suggest that higher levels of total physical activity, especially in the long-term, as well as specific types of physical activity including walking/bicycling and work/occupational activity, may be associated with decreased risk of age-related cataract among middle-aged and elderly women and men. On the other side, high levels of leisure time inactivity may be associated with increased risk of cataract. (more…)

Dr. David Gerber MD Associate Professor of Internal Medicine Division of Hematology and Oncology Harold C. Simmons Cancer Center at UT Southwestern Medical CenterMedicalResearch.com Interview with: Dr. David Gerber MD Associate Professor of Internal Medicine Division of Hematology and Oncology Harold C. Simmons Cancer Center at UT Southwestern Medical Center Medical Research: What are the main findings of the study? Dr. Gerber: Fewer than 3% of adult cancer patients in the United States are enrolled in clinical trials.  Increasingly numerous and stringent eligibility criteria are a major factor limiting participation in clinical trials.  We examined the longstanding and widespread practice of excluding patients with prior cancer from oncology clinical trials.  This policy presumably reflects concerns that a prior cancer would interfere with the conduct, outcomes, or interpretation of a clinical trial, although there is no clear evidence supporting that assumption. We examined more than 50 National Cancer Institute (NCI)-sponsored lung cancer clinical trials.  We found that 80% excluded patients with prior cancers.  This exclusion criterion was applied broadly, including to more than two-thirds of trials with non-survival endpoints.  We then examined national Surveillance Epidemiology and End Results (SEER)-Medicare linked data to estimate the proportion of patients who would be excluded from these trials due to prior cancer.  We found that up to 18% of potential patients are excluded for this reason alone.  In large phase 3 clinical trials, that corresponds to more than 200 patients.

Author Interviews, Esophageal, JAMA, University of Michigan / 01.10.2014

Megan A. Adams, MD Gastroenterology Fellow University of MichiganMedicalResearch.com Interview with Megan A. Adams, MD Gastroenterology Fellow University of Michigan   Medical Research: What are the main findings of the study? Dr. Adams: Surveys of doctors indicate that their fear of a malpractice lawsuit for missing a diagnosis of esophageal cancer might drive the overuse of tests called upper endoscopies in patients who are at low risk for the cancer. To examine whether this perception of medical liability risk accurately reflects the real likelihood of a malpractice claim, we looked at a national database of malpractice claims, and compared the rate of claims for delay in diagnosis of esophageal cancer in patients without alarm symptoms (weight loss, dysphagia, iron deficiency anemia), with the rate of claims alleging performance of an upper endoscopy without a good reason for performing the procedure. The database contained 278,220 claims filed against physicians in 1985-2012. The incidence of reported medical liability claims for failure to screen for esophageal cancer in patients without alarm features was quite low (19 claims in 11 years, 4 paid). In contrast, there were 17 claims in 28 years for complications of upper endoscopies with questionable indication (8 paid). (more…)

Chief Clinical Officer of iRhythm Technologies, Inc. Judy Lenane, R.N., M.H.A. Chief Clinical Officer of iRhythm Technologies, Inc.   Medical Research: What is atrial fibrillation and how common a problem is it among US adults? Dr. Gorelick: Nearly 3 million people in the US suffer from Atrial Fibrillation or “Afib,” an abnormal heart rhythm that causes the heart to beat rapidly and irregularly. While Afib can occur at any age, the incidence increases with age and the number of cases is expected to increase significantly in the coming years as the population ages. Approximately 5 percent of people 65 years and older and one in every 10 people over 80 years of age have Afib. It is more common in those with high blood pressure, heart disease or lung disease.

Rebecca Smith-Bindman, MD Professor in the Departments of Radiology; Epidemiology and Biostatistics; and Obstetrics, Gynecology and Reproductive Medicine UCSF San Francisco Calif.MedicalResearch.com Interview with: Rebecca Smith-Bindman, MD Professor in the Departments of Radiology; Epidemiology and Biostatistics; and Obstetrics, Gynecology and Reproductive Medicine UCSF San Francisco Calif. Medical Research: What are the main findings of the study? Dr. Smith-Bindman: New technology is rapidly developed in medicine, and its important to understand how that technology should be used to improve patient health outcomes. Sometimes the technology is far better than existing technology and it should replace the earlier technology, and sometimes it is not and therefore should not be used. In this clinical scenario – I e. patients who present to an emergency department with abdomen or back pain thought to possibly reflect kidney stones, ultrasound is a simpler, less expensive , and more readily available test in the emergency department setting and therefore if it is equal to CT with respect to patient outcomes, it should be used as the first test in these patients. Currently, CT is the test widely used for patients with suspected kidney stones. We assessed a large number of patients with suspected kidney stones seen at one of 15 large academic emergency medicine departments across the country. Patients were assigned to point of care ultrasound performed by an ED physician, radiology ultrasound or radiology CT. We assessed a broad range of patient centered outcomes and found each of the three tests we studied were equivalent in terms of these outcomes including complications related to missed diagnoses, related serious adverse events, time spent in the emergency department and repeated ED visits and hospitalizations. However, the exposure to ionizing radiation was around half as high in patients who underwent ultrasound as their first test, and thus ultrasound should be used as the first imaging test in patients with suspected nephrolithiasis.

Rashid Bashshur, PhD Senior Advisor for eHealth Professor Emeritus, Department of Health Management and Policy Executive Director, UMHS eHealth Center University of Michigan Health SystemMedicalResearch.com Interview with:  Rashid Bashshur, PhD Senior Advisor for eHealth Professor Emeritus, Department of Health Management and Policy Executive Director, UMHS eHealth Center University of Michigan Health System Medical Research: What are the Main findings of the study? Dr. Bashshur: The main findings can be summarized as follows:
  •  The prevalence of chronic disease is increasing due to the changing demographic composition of the population and unhealthy life styles. Chronic diseases are expensive, accounting for about 70% of health care expenditures;  but  they are amenable to telemedicine interventions.  These interventions consist of ongoing monitoring of patients living in their own home environments, engaging them in managing their health,  providing them with educational materials and the necessary tools to manage their life style mostly by avoiding risky behaviors and adopting healthy ones.
  • Telemedicine interventions consist of various configurations of technology (telephone, video, wired or wireless, automated or manual) , human resources (physicians, nurses, combinations, and patient populations at various levels risk levels or severity of illness, The interventions investigated to date also vary in terms of study design, duration of application (during the study period), and frequency of administration of the intervention.  Hence, the findings must be viewed from the perspective of the specific methodological attributes  of the studies that were performed.
  • Using only robust studies from 2000 to the near present, and limited to congestive heart failure, stroke and COPD.  With notable exceptions,  overall there is substantial and fairly consistent evidence of:
  • A decrease in use of service, including hospitalization, rehospitalization, and emergency depart visits as a result of the telemedicine intervention.
  • Improved health outcomes.
  • Improved event timing for stroke patients.
  • Reduced exacerbations of symptoms for COPD patients
  • Some interesting  trends  to be considered:
  • Frail and elderly patients, those with co-morbid conditions, and those in advanced stages of illness are not likely to benefit from telemedicine interventions, as compared to their counterparts.
  • Visual information as in videoconferencing proved superior to telephone only connection for the diagnosis and treatment of stroke patients.
  • There could be a tradeoff between extra nursing time versus reduced physician time in some settings, but the net effect is cost savings.
  • There seems to be a paradoxical telemedicine effect in terms of increasing longevity but no reduction in hospitalization, reported in few studies.

Kontos, Ph.D. Assistant Research Director UPMC Sports Medicine Concussion Program Associate Professor Department of Orthopaedic Surgery University of Pittsburgh Medical Research: What are the main findings of the study? Dr. Kontos: Our new Vestibular/Ocular Motor Screening (VOMS) examination was able to accurately identify nearly 90% of patients with a concussion. In our study of 64 concussed patients approximately five days post-injury and 78 healthy control-group patients who were administered VOMS by trained clinicians, we also found that more than 60% of patients with a concussion reported symptoms or had impairment on the VOMS following their injury. The VOMS, which was developed in conjunction with an interdisciplinary team of experts, assesses five areas of the vestibular ocular system: smooth pursuits, saccades (rapid eye movement), horizontal vestibular ocular reflex (VOR), visual motion sensitivity (VMS), and near-point-of-convergence (NPC) distance.

Author Interviews, Mental Health Research, NIH / 15.09.2014

MedicalResearch.com Interview with: Dr Oliver J Robinson Ph.D. Section on Neurobiology of Fear and Anxiety, National Institute of Mental Health, NIH, Bethesda, MD, Institute of Cognitive Neuroscience University College London, London, UK Medical Research: What are the main findings of the study? Dr. Robinson: This study is looking at a symptom of anxiety disorders known as “negative affective bias”. This describes the tendency of people with anxiety disorders to focus on negative or threatening information at the expense of positive information. We completed a number of previous studies looking at so called “adaptive” anxiety in healthy individuals – this is the normal, everyday anxiety that everyone experiences; walking home in the dark, for instance (in these prior studies we used unpredictable electrical shocks to make people anxious and stressed). When we made healthy people transiently anxious in this way we showed that this was also associated with negative affective bias and driven by a specific brain circuit: the dorsal medial prefrontal (anterior cingulate) cortex—amygdala aversive amplification circuit. In this study we showed that the same circuit that was engaged by transient anxiety in our healthy sample was actually engaged ‘at baseline’ (i.e. without stress) in our patient group. This suggests that this mechanism which can be temporarily activated in healthy controls becomes permanently ‘switched on’ in our patient group. This might explain why people with anxiety disorders show persistent ‘negative affective biases’. Furthermore, the extent to which this circuit was turned on correlated with self-reported anxiety. That is to say the more anxious an individual said they were, the greater the activity in this circuit. Therefore, there seems to be more of a dimension or scale of anxiety, rather than a simple well/unwell diagnosis. (more…)

Dr. Brass : Among the 11,400 surveys mailed out to all members of the Northern California Chapter of the National Multiple Sclerosis Society, 2,810 (24.6%) were returned. Of these, 2,375 (84.5%) met the inclusion criteria. Among the completed surveys, 898 (37.8%) screened positive for obstructive sleep apnea, 746 (31.6%) for moderate to severe insomnia, and 866 (36.8%) for restless legs syndrome.  In contrast, only 4%, 11%, and 12% of the cohort reported being diagnosed by a health care provider with obstructive sleep apnea, insomnia, and restless legs syndrome, respectively. Excessive daytime sleepiness was noted in 30% of respondents based on the Epworth Sleepiness Scale. More than 60% of the respondents reported an abnormal level of fatigue based on the Fatigue Severity Scale.  There was also an increased risk between complaints of Fatigue based on screening positive for the Fatigue Severity Scale  and screening positive for Obstructive Sleep Apnea  (1.850, with a 95% p-value < 0.001).

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…)

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…)

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.

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.

Dr. Bingener: Other investigators have shown that preoperative quality of life is a predictor for postoperative survival in colon and pancreas cancer surgery. In this study we looked as preoperative quality of life as a predictor for postoperative complications. The main findings of the study were that patients who had a deficit in their quality of life before surgery had a 3 times higher risk of a serious complication before leaving the hospital than patients who had normal quality of life (16% vs 6 %), independent of gender, race, tumor stage or laparoscopic or open colectomy. Patients with serious complications before leaving the hospital also were older and had more other medical problems than patients without complications. Further, patients who had a complication stayed in the hospital longer and their postoperative quality of life was worse (more…)

Anderson, MD, MMSc Neurocritical Care | Acute Stroke Center for Human Genetic Research Massachusetts General Hospital Harvard Medical School Broad Institute of Harvard and MIT Medical Research: What are the main findings of the study? Dr. Anderson: Previous studies have linked Apolipoprotein E (APOE) epsilon variants with spontaneous intracerebral hemorrhage (ICH) particularly in the lobar (cortical and subcortical) regions of the brain, but it was not known whether this association would extend to warfarin-related ICH, or whether the risk of intracerebral hemorrhage on warfarin would be multiplicatively compounded by APOE epsilon allele status.  Our results demonstrate that APOE e2 and e4 variants are associated with more than a two-fold risk of lobar ICH for patients on warfarin, in comparison to warfarin-exposed individuals without ICH.  This observed association was strongest when analyzing subjects with definite or probable Cerebral Amyloid Angiopathy (CAA), as defined by the Boston Criteria.  No association between APOE e2 or e4 and non-lobar ICH was identified following our replication phase.  Furthermore, we did not detect an interaction between APOE status and warfarin status in ICH subjects using a case-only design.

Dr. Singh: Our research team used a monetary incentive delay paradigm to measure fronto-limbic activity and connectivity associated with anticipation and receipt of reward and loss in healthy offspring of parents with bipolar I disorder. We found that compared to youth offspring without any family history of psychopathology, high-risk offspring had aberrant prefrontal and cingulate activations and connectivity during reward processing. Further, greater striatal, amygdalar, and insula activations while anticipating and receiving rewards and losses were associated with greater novelty-seeking and impulsivity traits in high-risk youth.
