Author Interviews, Brigham & Women's - Harvard / 28.08.2014

Christopher D. Anderson, MD, MMSc Neurocritical Care | Acute Stroke Center for Human Genetic Research Massachusetts General Hospital Harvard Medical School Broad Institute of Harvard and MITMedicalResearch.com Interview with: Christopher D. 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.

MedicalResearch.com Interview with: Gayatri Patel, MD, MPH Division of General Medicine UC Davis Medical CenterMedicalResearch.com Interview with: Gayatri Patel, MD, MPH Division of General Medicine UC Davis Medical Center Medical Research: What are the main findings of the study? Dr. Patel: In this systematic review and meta-analysis, we sought to determine the effectiveness of photodynamic therapy (PDT) for the treatment of actinic keratoses relative to other common treatments. We included only randomized controlled trials and preformed a meta-analysis on homogenous studies. The primary finding of the study was that PDT has a better chance of removing actinic keratoses on the face or scalp than treatment with cryotherapy. (more…)

MedicalResearch.com Interview with: Manpreet K. Singh, MD MS Assistant Professor of Psychiatry and Behavioral Sciences Akiko Yamazaki and Jerry Yang Faculty Scholar in Pediatric Translational Medicine Stanford University School of Medicine Medical Research: What are the main findings of the study? 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.

Author Interviews, Case Western, Lyme / 22.08.2014

Daniel Salkeld, PhD Lecturer & Research Associate Stanford Woods Institute for the Environment Professor Colorado State UniversityMedicalResearch.com Interview with: Daniel Salkeld, PhD Lecturer & Research Associate Stanford Woods Institute for the Environment Professor Colorado State University Medical Research: What are the main findings of the study that were just published in Ticks and Tick-borne Diseases? Dr. Salkeld: The primary findings of this new study show that western black-legged ticks, which can transmit Lyme disease, are active throughout the year in Northwest California, making the threat of Lyme disease year-round phenomenon. More specifically, my colleagues from California Department of Public Health Vector-borne Disease Section and University of California, Berkeley and I found that the activity of Western Black-legged ticks (Ixodes pacificus), which are the ticks most commonly known to carry Lyme disease (caused by Borrelia burgdorferi) in Northwest California, is largely predictable and year-round. In general, tick larvae (newly hatched immature ticks) are active April to June, and sometimes activity extends into October, while adult ticks are active from October to May. Nymphal ticks (the tick stage following larvae and preceding adults) are active from January to October but peak from April-June. This is important because nymphs are responsible for most Lyme disease infections. (more…)

Mallika L. Mendu, M.D. Division of Renal Medicine Brigham and Women’s Hospital Boston, MA 02115.MedicalResearch.com Interview with: Mallika L. Mendu, M.D. Division of Renal Medicine Brigham and Women’s Hospital Boston, MA 02115. Medical Research: What are the main findings of the study? Dr. Mendu: Our study found that implementation of a chronic kidney disease (CKD) checklist, a tool that succinctly and clearly outlines CKD management guidelines, in a primary care clinic improved adherence to a number of significant management guidelines. We conducted a prospective study during a one year period among 13 primary care providers, four of whom were assigned to use a CKD checklist incorporated into the electronic medical record during visits with patients with CKD. Patients whose providers utilized a CKD checklist had higher rates of adherence to annual albuminuria testing, parathyroid hormone testing, phosphate testing, achieving a hemoglobin A1c target<7, documentation of avoidance of nonsteroidal anti-inflammatory drugs, use of an angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker and vaccination for annual influenza and 5-year pneumococcus.

MedicalResearch.com Interview with: Sosena Kebede, MD, MPH Assistant Professor of Medicine, Department of Medicine Associate Faculty, the Armstrong Institute for Patient Safety and Quality, Johns Hopkins School of Medicine Faculty, Department of Health Policy and Management and Baltimore, MD 21287Sosena Kebede, MD, MPH Assistant Professor of Medicine, Department of Medicine Associate Faculty, the Armstrong Institute for Patient Safety and Quality, Johns Hopkins School of Medicine Faculty, Department of Health Policy and Management and Baltimore, MD 21287 Medical Research: What are the main findings of the study? Dr. Kebede: There were 3 main findings in this study: 1.       Patients’ understanding of aspects of their hospital care is suboptimal on the domains of knowledge of diagnoses, indications for the medications they take and the types of procedures/tests they get. Some forms of poor shared understanding could have potentially serious implications for their health and for future care such as identifying a prescribed antidepressant as a blood thinner or mistaking an echocardiogram a left heart catheterization or thinking a liver cyst is a liver cancer. Other forms of poor shared understanding such as not accurately identifying why a procedure is done or what the results of the procedure show (a finding not discussed in the research letter) may seem less consequential  but raise the issue of informed consent, patient empowerment and may alsoraise questions about patient and physician behavior towards appropriate use of in-patient procedures. Some of the questions we could ask here include: would patients demand more or less procedures if they had better understanding of what the procedures entail, and why they are beingordered? Conversely, would physicians recommend more or less of in-patient procedures, when they encounter patients whose understanding of procedure indications are optimal? (more…)

Frank van Hees, MSc Researcher, Department of Public Health, Erasmus MC Rotterdam, The NetherlandsMedicalResearch.com Interview with: Frank van Hees MSc Erasmus University Medical Center Rotterdam, the Netherlands   Medical Research: What are the main findings of the study? Answer: Many U.S. elderly are screened for colorectal cancer more frequently than recommended: One in every five elderly with a negative screening colonoscopy result undergoes another screening colonoscopy within 5 years’ time instead of after the recommended 10 years. Moreover, one in every four elderly with a negative screening colonoscopy result at age 75 or older receives yet another screening colonoscopy at an even more advanced age. Our study shows that, in average risk individuals, these practices are not only a waste of scarce health care resources: often they are also associated with a balance among benefits, burden, and harms that is unfavorable for those being screened.

Dr. Juliane Bingener-Casey, M.D. Mayo Clinic in Rochester, Minn.MedicalResearch.com Interview with: Dr. Juliane Bingener-Casey, M.D. Mayo Clinic in Rochester, Minn.   Medical Research: What are the main findings of the study?   Dr. Bingener-Casey: “About half of patients seeking emergency care for gallbladder problems were immediately admitted and underwent urgent cholecystectomy, the other half went home. The half that went home was younger and had lower WBC counts, lower neutrophils and less people with elevated temperature than the patients immediately admitted. Of the half that went home, 31% returned at least once to the ED within 30 days and 20% were admitted to undergo urgent cholecystectomy after the return visit, 55% percent of those within 7 days of the initial ED visit. Patients who failed the elective treatment plan had similar WBC counts but were more likely to have an ASA >3, slightly higher creatinine and higher average maximum VAS pain score. Patients who were less than 40 years old or older than 60 years were more likely to fail the elective pathway.” (more…)

Professor Fritz H Schröder Department of Urology, Erasmus University Medical Center Rotterdam, NetherlandsMedicalResearch.com Interview with: Professor Fritz H Schröder Department of Urology, Erasmus University Medical Center Rotterdam, Netherlands Medical Research: What are the main findings of the study? Professor Schröder: I consider as the main finding that we could report a continuing effect of PSA driven screening on prostate cancer mortality for men aged 55 – 69 years in the screen arm of our study after 13 years of follow-up. The absolute reduction in the risk of death from prostate cancer amounts to 1.28 per 1000 men randomized to the screening arm. This translated into numbers to be invited to screening and numbers needed to be diagnosed to save one prostate cancer death of 781 and 27. These figures show an increasing effect with increasing time of follow-up. The relative risk reduction related to the control arm has remained unchanged with respect to the 11 year follow-up period. For men who actually participated and were screened the relative risk reduction amounted to 27%, the figure most applicable to men who consider to be tested. (more…)

Dr. Bing Lu, M.D., Dr.P.H. Division of Rheumatology Immunology & Allergy Brigham & Women's Hospital and Harvard Medical School Boston, MA 02115MedicalResearch.com Interview with: Dr. Bing Lu, M.D., Dr.P.H. Division of Rheumatology Immunology & Allergy Brigham & Women's Hospital and Harvard Medical School Boston, MA 02115 Medical Research: What are the main findings of the study? Dr. Lu: In two large cohorts of women, we observed that being obese increased the risk of rheumatoid arthritis in women by 40–70% depending on age and serologic status. The highest risk for rheumatoid arthritis was among women who were overweight or obese at age 18 years, emphasizing the public health importance of combating the obesity epidemic at all ages. Our study implicates being overweight or obese throughout adult life as a risk factor in the development of seropositive and seronegative RA for women diagnosed with rheumatoid arthritis at age 55 years or younger. The attenuated association between BMI and rheumatoid arthritis diagnosed at older ages may reflect differences in the pathophysiology of RA diagnosed at earlier ages compared with that diagnosed at older ages, or may be a result of the limitations of BMI as a measure of total fat mass as women age.

Dr. John C. Lieske, MD Mayo Clinic, Rochester, MNMedicalResearch.com Interview with Dr. John C. Lieske, MD Mayo Clinic, Rochester, MN Medical Research: What are the main findings of the study? Dr. Lieske: We followed 11 women before, 6 and 12 months after Roux en Y gastric bypass surgery.  The patients successfully lost weight as mean BMI fell from 46 kg/m2 preoperatively to 28 kg/m2 postoperatively.   Mean serum creatinine did not significantly change from baseline (0.8 mg/dl) to 12 months (0.7 mg/dl).  Hence mean GFR estimated by the CKD-EPI equation (eGFR) did not significantly change from 84 ml/min/1.73 m2 (baseline) to 90 ml/min/1.73 m2 (12 months).  However, GFR measured by iothalamate clearance (mGFR) significantly decreased from 108 ml/min/1.73m2 (121 ml/min) to 85 ml/min/1.73 m2 (90 ml/min).

Author Interviews, Hematology, NEJM, Sloan Kettering, Transplantation / 31.07.2014

MedicalResearch.com Interview with: Richard J. O'Reilly, MD Memorial Sloan Kettering Cancer Center Medical Research: What are the main findings of the study? Dr. O'Reilly: 1.       In a comparison of the results of HLA-matched sibling transplants with other established transplant approaches, including T-cell depleted half-matched parental marrow grafts, unmodified transplants from matched unrelated donors and cord blood transplants in the current era (2000-2009), transplants from donors other than HLA-matched siblings had 5 year survival outcomes similar to those of matched siblings when applied to young infants (≤ 3.5 months of age) or infants of any age that were not infected at the time of transplants. Thus any child born with SCID can now be successfully transplanted. 2.       Active infection at the time of transplant significantly reduced chances of long-term survival for all infants except those who received transplants from HLA-matched siblings. Thus, infection is a dominant determinant of transplant outcome.  Control of treatable infections prior to transplant should be a major clinical objective. 3.       Treatment with chemotherapy containing busulfan significantly enhances the likelihood of recovering a normal ability to make antibodies and fosters better recovery of T-cells that provide cell mediated immunity, and may be an acceptable risk in uninfected infants. However, use of any chemotherapy prior to transplant in an infant who is infected, greatly decreases chances of survival. In infected patients who lack a matched sibling, T-cell depleted transplants from half matched related donors had the best outcomes. (more…)

Dr. Hultman: Using a mouse model of stress-induced psychiatric dysfunction, we found that the brainwave patterns in two key brain regions (prefrontal cortex, PFC and amygdala, AMY) encode for susceptibility to such dysfunction. Furthermore, such susceptibility can be predicted from the brainwave patterns in these regions before the onset of stress. (more…)

MedicalResearch.com Interview with: Jeremiah R. Brown, PhD MS Assistant Professor of Health Policy and Clinical Practic The Dartmouth Institute Lebanon, NHMedicalResearch.com Interview with: Jeremiah R. Brown, PhD MS Assistant Professor of Health Policy and Clinical Practic The Dartmouth Institute Lebanon, NH   Medical Research: What are the main findings of the study? Dr. Brown: Using simple team-based quality improvement methods we prevented kidney injury in 20% of patients having a procedure in the cardiac catheterization lab.  Among patients with pre-existing kidney disease, we prevent kidney injury in 30% of patients. We believed that using a team-based approach and having teams at different medical centers in northern New England learn from one-another to provide the best care possible for their patients.  Some of the most innovative ideas came from these teams and identified simple solutions to protect patients from kidney injury from the contrast dye exposure; these included:
  • Getting patients to self-hydrate with water before the procedure (8 glasses of water before and after the procedure),
  • Allow patient to drink fluids up to 2-hours before the procedure (whereas before they were "NPO" for up to 12 hours and came in dehydrated),
  • Training the doctors to use less contrast in the procedure (which is good for the patient and saves the hospital money),
  • and creating stops in the system to delay a procedure if that patient had not received enough oral or IV fluids before the case (rather, they would delay the case until the patient received adequate fluids).Our success was really about hospital teams talking and innovating with one another instead of competing in the health care market, which resulted in simple, homegrown, easy to do solutions that improved patient safety.

Medical Research: What are the main findings of the study? Dr. Blosnich: I think there are two main findings from our study: First, since the beginning of the All-Volunteer U.S. military in 1973, there has been a shift in childhood experiences among men who have served in the military. Second, the childhood experiences of women who have served in the military have been largely similar across the Draft and All-Volunteer Eras. (more…)

Dr. Bryan K. Woodruff Assistant Professor of Neurology Mayo Clinic, ArizonaMedicalResearch.com Interview Invitation Dr. Bryan K. Woodruff Assistant Professor of Neurology Mayo Clinic, Arizona Medical Research: What are the main findings of the study? Dr. Woodruff: There is evidence in the medical literature supporting a negative impact of losing a spouse for health conditions such as cancer or cardiovascular disease, but this has not been evaluated in terms of the impact of widowhood on the development of dementia.  We used the National Alzheimer’s Disease Coordinating Center (NACC) database, which pools data gathered by multiple federally-funded Alzheimer’s disease research centers to try to answer this question.  Specifically, we looked at the age at which individuals ultimately developed dementia in both individuals who lost their spouse and in those who remained married over the course of the study.  Surprisingly, the data we analyzed did not support a negative impact of losing a spouse in individuals who had no cognitive difficulties when they entered the study, and we saw a paradoxical effect of widowhood in those with mild cognitive impairment (MCI).

Fiellin, M.D. Associate Professor of Medicine Director, play2PREVENT Lab Yale University School of Medicine New Haven, CT 06510 Medical Research: What are the main findings of the study? Dr. Fiellin: The current findings are part of a larger study evaluating an interactive evidence-based video game, PlayForward: Elm City Stories, developed on the iPad and targeting risk reduction and HIV prevention in 333 young teens (ages 11-14). The larger study is examining a range of outcomes including knowledge, intentions, self-efficacy and actual behaviors and we are collecting at baseline, 6 weeks, 3, 6, 12, and 24 months. We are examining these outcomes in our experimental group compared with a control group playing a set of off-the-shelf games on the iPad. The current findings of the 196 teens who have completed the 6 weeks of gameplay and for whom we have baseline and 3 month data, reveal that, while the two groups had no differences in their baseline HIV risk knowledge, the PlayForward group had statistically significant gains in knowledge at 6 weeks (p<0.0001), sustained at 3 months (p<0.01). In addition, examining the association between exposure to the game and performance on the standardized assessments revealed that the number of game levels completed (a measure of exposure to the intervention) was positively correlated with knowledge gains measured at 3 months (r=0.42; p<0.001).

Dr. Cai: We conducted a genome-wide association study in East Asians to search for additional genetic changes that are linked to breast cancer development. The study was conducted as part of the Asia Breast Cancer Consortium, which includes 22,780 women with breast cancer and 24,181 control subjects. We found DNA sequence changes in two genes, PRC1 and ZC3H11A, and a change near the ARRDC3 gene were associated with breast cancer risk. These results were also replicated in a large consortium, including 16,003 breast cancer cases and 41,335 control subjects of European ancestry. (more…)

Aakriti Gupta, MD, MBBS Center for Outcomes Research and Evaluation Yale-New Haven Hospital, New Haven, ConnecticutMedicalResearch.com Interview with: Aakriti Gupta, MD, MBBS Center for Outcomes Research and Evaluation Yale-New Haven Hospital, New Haven, Connecticut Medical Research: What were the main findings? Dr. Gupta: Using a national database, we found that heart attack hospitalization rates for patients under the age of 55 have not declined in the past decade while their Medicare-age counterparts have seen a 20 percent drop. We also found that among younger patients below 55 years of age, women fare worse because they have longer hospital stays, and are more likely to die in the hospital after a heart attack. Young women were also more likely to have higher prevalence of co-existing medical conditions including diabetes, high blood pressure and higher cholesterol levels. Overall, all patient groups in the study saw increases in these conditions including diabetes and high blood pressure in the past decade. (more…)

Steven Grinspoon, MD Professor of Medicine, Harvard Medical School Director, MGH Program in Nutritional Metabolism Co-Director, Nutrition Obesity Research Center at Harvard Massachusetts General Hospital Boston, MA 02114MedicalResearch.com Interview with Steven Grinspoon, MD Professor of Medicine, Harvard Medical School Director, MGH Program in Nutritional Metabolism Co-Director, Nutrition Obesity Research Center at Harvard Massachusetts General Hospital Boston, MA 02114 Medical Research: What are the main findings of the study? Dr. Grinspoon: The primary finding is that tesamorelin, a hypothalamic peptide that increases the endogenous pulsatile secretion of growth hormone, reduced liver fat in HIV-infected patients with increased visceral (abdominal) fat.  Increased visceral fat is very closely linked with increased liver fat in HIV patients, but the effects on liver fat were not known.  Our data show that tesamorelin reduces liver fat in conjunction with decreasing visceral fat, which may be clinically important for patients with HIV-infection who have both increased abdominal fat and fatty liver disease. In addition the study demonstrated that this treatment strategy was neutral to glucose by the end of the 6 month study. (more…)
