MedicalResearch.com Interview with: Prof. Olivier Lambotte, MD, PHD Professor of Internal Medicine Paris XI University Medical School Research Director Control of Chronic Viral Infections DepartmentProf. Olivier Lambotte, MD, PHD Professor of Internal Medicine Paris XI University Medical School Research Director Control of Chronic Viral Infections Department MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Immune checkpoint inhibitors (ICIs) anti-programmed death-1 (PD-1) or anti-programmed death ligand-1 (PD-L1) have proven efficacy in the treatment of many cancers but patients may experience immune-related adverse events (irAEs). Immune checkpoint inhibitors is usually stopped when grade 2 or higher irAE occur. Data are very limited  on the safety of resuming treatment after such an event. We  studied all adult patients referred to the ImmunoTOX toxicity review board at the Gustave Roussy cancer center (Villejuif, France) in 2015-2017 with  irAE grade 2 or higher for whom the  rechallenge was questioned. Among 93 patients with a broad spectrum of cancers, 40 patients (43%) were rechallenged with the same anti-PD-1 or anti-PD-L1. The rechallenged and non-rechallenged groups did not differ in terms of age, time to initial irAE, irAE severity, or steroid use. With a median follow-up period of 14 months, the same irAE or a different irAE occurred in 22 patients (55%). The second irAEs were not more severe than the first. Earlier initial toxicity was associated with more frequent irAE recurrence.

Author Interviews, Dermatology, FDA / 06.06.2019

MedicalResearch.com Interview with: Stephanie L. Kuschel, MD Indiana University School of Medicine Indianapolis, IN, 46202 Robert Dellavalle, MD, PhD, MSPH Professor of Dermatology and Public Health University of Colorado School of Medicine Colorado School of Public Health Chief, Dermatology Service US Department of Veterans Affairs Eastern Colorado Health Care System Denver, CO 80220  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Physicians can serve as external experts and voting members of FDA advisory committee panels, which help determine if a drug is acceptable for the US market. Considering that financial conflicts of interest (FCOI) have been shown to influence voting member habits, the FDA has regulations in place to minimize these FCOI. However, the FDA can grant waivers for some financially conflicted individuals if they meet certain requirements (like offering key insights that may out-weigh the risk of a possible FCOI). Additionally the FDA does not make stipulations regarding post-advisory role financial relationships. In fact, many former FDA committee advisors later engage in financial relationships with pharmaceutical companies. Some worry these post-hoc financial relationships could pose an ethical dilemma whereby future FDA advisory members are incentivized to alter their voting habits in expectation of future rewards. Others argue the situation may be more complex than expected. For example, the author of one study, found that while there was evidence for a pro-industry voting bias among committee members with exclusive financial relationships to the sponsoring manufacturer (of the drug under review), this was not the case for members with nonexclusive financial ties to both the sponsor and its competitors 1. Furthermore, the author found that advisors with many corporate ties were (on average) actually more likely than their peers without any financial ties to vote against the sponsor. The author argued that these advisors were more likely to be experienced researchers, and their voting habits may reflect their experience evaluating medical research. While this author and others have offered valuable insights into financial relationships of advisors during their advisory role, unfortunately little information is available regarding post-advisory role financial relationships and whether these relationship have any influence on the integrity of the voting process. The purpose of our study was to review Open Payment data on industry payments to former physician FDA dermatologic drug committee members.  (more…)
Author Interviews, Opiods, Pain Research, Sleep Disorders / 05.06.2019

MedicalResearch.com Interview with: Nicole Tang, D.Phil, C.Psychol (Reader) Department of Psychology Warwick Sleep and Pain Lab University of Warwick MedicalResearch.com: What is the background for this study? What are the main findings? Response: Current guidelines recommend non-opioid therapy as the preferred treatment of chronic non-malignant (CNP) pain, with opioids reserved to situations “when benefits for pain and function are expected to outweigh risks” [1,10]. Whilst the effectiveness of opioid therapy is usually measured in terms of pain outcomes, less is known about its effect on day-to-day functions. A particular function of concern to patients with chronic non-malignant pain is the ability to get a good night's sleep. The current systematic review has identified a set of papers with relevant outcomes regarding the effect of opioid therapy on sleep quality and sleep architecture in CNP patients. It extends our understanding from the drug's respiratory depression effect in healthy individuals to the potential risks and utility of opioid therapy for chronic non-malignant pain patients with sleep disturbances. Whilst the narrative synthesis and the exploratory meta-analysis of a subset of data both suggest that the use of opioid therapy is associated with an overall report of sleep quality improvement, such an improvement is not consistently replicated across studies or substantiated by improvements in sleep parameters linked to deeper and better-sleep quality. Moreover, the improvement may be accompanied by undesirable side effects and increased daytime sleepiness that contradict with the very idea of improved sleep quality. We are also painfully aware of the methodological limitations of the studies reviewed; their exposure to different sources of biases has heightened the risk of result inflation. To many patients with chronic non-malignant pain, improved sleep is a top priority when evaluating the performance of a new drug and non-drug intervention. If we were to advance our current understanding of the opioid-sleep relationship, future trials need to be designed with this interdisciplinary question in mind such that validated measures of sleep can be incorporated as an outcome measure alongside pain.

Author Interviews, Baylor University Medical Center Dallas, Gastrointestinal Disease / 28.05.2019

MedicalResearch.com Interview with: Dr. Rhonda Souza, MD Baylor University Medical Center Center for Esophageal Research Dallas, TX 75246  MedicalResearch.com: What is the background for this study?   Response: Eosinophilic esophagitis (EoE) is a modern disorder of the esophagus caused by an allergy to certain foods. EoE causes esophageal symptoms like difficulty swallowing and heartburn and is diagnosed when biopsies of the esophagus taken during endoscopy show numerous eosinophils, which are a type of inflammatory blood cell.  There are few established treatments for EoE. One such treatment is a diet that eliminates the offending food allergens, and another is to use steroids to reduce the number of eosinophils in the esophagus. However, the most common treatment for adults with eosinophilic esophagitis is to use proton pump inhibitors (PPIs), which block the proton pumps in stomach cells that make acid.  In earlier studies, we found that PPIs also can block proton pumps in esophageal cells.  Those proton pumps are activated by chemicals that the body produces in response to allergens including interleukin (IL)-13 or IL-4.  Il-13 and IL-4, which cause the esophagus to produce eotaxin-3, a molecule that attracts eosinophils. What remained unknown, however, was the mechanism whereby these interleukins activate proton pumps in the EoE esophagus. In our present study, we explored whether IL-4 works by increasing calcium levels in esophageal cells from EoE patients. (more…)
Author Interviews, Brigham & Women's - Harvard, JAMA, Lipids / 28.05.2019

MedicalResearch.com Interview with: Samia Mora, MD, MHS Associate Physician, Brigham and Women's Hospital Associate Professor of Medicine, Harvard Medical School Brigham and Women's Hospital Department of Medicine Preventive Medicine Boston, MA 02115  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Lipid testing plays a major role in cardiovascular disease (CVD) risk screening, prediction, and treatment. In the past decade, several pivotal studies (including the Women’s Health Study, the Copenhagen City Heart Study, and the Copenhagen General Population Study) compared populations of individuals who had fasting lipid testing with populations of individuals who had nonfasting lipid testing, and found that non-fasting lipids were at least as good as fasting lipids in cardiovascular risk screening and predicting CVD risk. To date, however, no study has examined the cardiovascular predictive value of lipids measured on the same individuals who had both fasting and nonfasting lipid testing. This is important because individual-level variability in fasting versus nonfasting lipids may not be captured when looking at population-level risk associations, and evidence from randomized studies is lacking. Furthermore, it is unclear whether substituting nonfasting lipids would misclassify cardiovascular risk for individuals who may be eligible for statin therapy. (more…)
Author Interviews, Cognitive Issues, Gender Differences / 24.05.2019

MedicalResearch.com Interview with: Tom Chang PhD, BS, MIT Associate Professor of Finance and Business Economics Marshall School of Business MedicalResearch.com: What is the background for this study? What are the main findings? Response: There have been many studies showing that women prefer higher indoor temperatures than men, however nobody looked at the effect of temperature on performance. We show that the battle for the thermostat is not just about the comfort. It is much more – in our experiment, women’s cognitive functioning is the best at high temperatures, whereas men’s at low temperatures. Significantly, the positive effect of increased temperatures on women’s performance is much stronger than the negative effect on men. The most surprising was that the effect of temperature on women is so strong. For instance, at low temperatures, men outperform women in a simple math task. However, when we increase the temperature, women become better and better (1.76% increase of solved tasks with each 1 Celsius increase), and at high temperatures women and men perform on the same level – the gender difference disappears.  (more…)
Author Interviews, Immunotherapy, NEJM, Pulmonary Disease / 22.05.2019

MedicalResearch.com Interview with: Gerard J. Criner, MD, FACP, FACCP Chair and Professor, Thoracic Medicine and Surgery Lewis Katz School of Medicine Temple University  MedicalResearch.com: What is the background for this study? Response: An earlier, Phase II trial of benralizumab found a non-statistically significant reduction in COPD exacerbation rate for patients with eosinophilic inflammation in the airways. In this Phase III trial, the researchers sought to discover whether benralizumab's ability to deplete the airways of blood eosinophils in patients with eosinophilic inflammation would lead to a reduction in COPD exacerbations. The Phase III, randomized, double-blind, placebo-controlled, parallel-group clinical trials GALATHEA and TERRANOVA evaluated the efficacy and safety of benralizumab for the prevention of exacerbations in patients with moderate to very severe COPD, eosinophilic inflammation, and increased risk of exacerbations. Benralizumab is a type of drug called an interleukin-5 receptor alpha-directed cytolytic monoclonal antibody. It is approved by the FDA for the treatment of severe eosinophilic asthma. (more…)
Accidents & Violence, Author Interviews, JAMA / 20.05.2019

MedicalResearch.com Interview with: XinQi Dong Director, Institute for Health, Health Care Policy, and Aging Research Henry Rutgers Distinguished Professor of Population Health Sciences Professor, Department of Medicine - Division of General Internal Medicine, Robert Wood Johnson Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Interpersonal violence is a substantial public health issue across all socio-demographic and socioeconomic strata globally. A depth of prior studies have found that victims of childhood sexual abuse might have higher risks of re-experiencing sexual violence as adults. But the “re-victimization” phenomenon has been insufficiently examined among the rapidly growing aging populations. There lacks examinations about life-course violence experiences and the accumulative effect of which in older ages. Our study examined three most common forms of interpersonal violence (child maltreatment, intimate partner violence, and elder abuse) across the life span and found an interconnectedness among them. Individuals with a history of child maltreatment and/or intimate partner violence had two to six times higher risks of elder abuse compared to those without a past experience of the violence.  (more…)

Abdel Magid, MHS, PhDPostdoctoral ScholarDepartment of Health Research & PolicyStanford UniversityHoda S. Abdel Magid, MHS, PhD Postdoctoral Scholar Department of Health Research & Policy Stanford University MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Dr. Hoda Magid, my former graduate student, and I wanted to examine whether owning promotional items for e-cigarettes and other non-cigarette products predicted youth use of those products.  Other studies have examined whether ownership of coupons, samples, and other promotional materials influenced cigarette use, but no longitudinal study examined other tobacco products. Our findings show that non-tobacco using youth who own items to promote e-cigarettes and other alternative tobacco products are twice as likely to use alternative tobacco products a year later.

MedicalResearch.com Interview with: Haishan Zeng, PhDDistinguished ScientistImaging Unit - Integrative Oncology DepartmentBC Cancer Research CentreProfessor of Dermatology, Pathology, and Physics, University of British ColumbiaVancouver, BC, Canada Haishan Zeng, PhD Distinguished Scientist Imaging Unit - Integrative Oncology Department BC Cancer Research Centre Professor of Dermatology, Pathology, and Physics, University of British Columbia Vancouver, BC, Canada  MedicalResearch.com: What is the background for this study? What are the main findings? Response: We developed a fast multiphoton microscope system that enables clinical imaging of the skin at the level of cellular resolution. With this system, we can see microstructures inside of the skin without cutting into it. We subsequently conceived the idea of directly treating the microstructures that are responsible for disease. We increased the laser power to generate intense localized heat to destroy the targeted structure. In this study, we demonstrated the feasibility of this new treatment by targeting and closing single blood vessels using our new microscope.  (more…)

What are the main findings?  Response: Dog ownership is common in the Western society but little is known about what actually makes people get a dog. We conducted a twin study to understand whether the genetic make-up has an influence on this choice. We found that more than 50% of the differences in dog ownership is explained by genetic variants.  (more…)
Author Interviews, Diabetes, Ophthalmology, Regeneron / 17.05.2019

MedicalResearch.com Interview with: Robert L. Vitti, MD, MBA Vice President and Head, Ophthalmology Regeneron Pharmaceuticals Dr. Vitti discusses the recent announcement that the FDA has approved EYLEA to treat all stages of diabetic retinopathy. MedicalResearch.com: Can you provide additional background on this approval? Would you briefly explain diabetic retinopathy and it's impact on patients? Response: The FDA has approved EYLEA (aflibercept) Injection to treat all stages of diabetic retinopathy (DR). DR is the leading cause of blindness among working-aged American adults. Approximately 8 million people live with DR, a complication of diabetes characterized by damage to the blood vessels in the retina (per 2010 data). The disease generally starts as non-proliferative diabetic retinopathy (NPDR) and often has no warning signs or symptoms. Over time, NPDR often progresses to proliferative diabetic retinopathy (PDR), a stage in which abnormal blood vessels grow on the surface of the retina and into the vitreous cavity, potentially causing severe vision loss.

MedicalResearch.com Interview with: sneakers-walkingFrancesco Zaccardi, MD, PhD Clinical Epidemiologist Assistant Director Leicester Real World Evidence Unit Leicester Diabetes Centre UK MedicalResearch.com: What is the background for this study? Response: The role of excess body weight on mortality has been extensively investigated during the last decades. Studies from several countries have also shown, however, that the risk of death in persons who are overweight or obese is lower if their fitness, a parameter indicating cardio-pulmonary health, is higher. Most of these studies reported the beneficial effect of fitness in terms of relative risk reduction, for example 20% reduction of risk of death. Relative estimates, though, are difficult to interpret. (more…)

Author Interviews, Medical Imaging, Mental Health Research, UCSD / 13.05.2019

MedicalResearch.com Interview with: Dr. Mingxiong Huang, PhD Professor, Electrical and Computer Engineering University of California, San Diego MedicalResearch.com: What is the background for this study?   Response: Combat-related mild traumatic brain injury (mTBI) is a leading cause of sustained impairments in military service members and Veterans. Yet, conventional neuroimaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) are typically insensitive to physiological alterations caused by mild and some moderate TBIs. With funding from the VA, we have pursued in developing sensitive imaging markers based on magnetoencephalography (MEG) for mTBI. This paper reflects the news MEG findings in this research field.  (more…)

MedicalResearch.com Interview with: Thomas M Van Vleet PhD Posit Science  Dr. Tom Van Vleet,  presented results on a common symptom of stroke and acquired brain injury (hemi-spatial neglect) at the American Academy of Neurology May 2019 MedicalResearch.com: What makes this study newsworthy? Response For the first time ever a highly-scalable intervention — computerized brain training (BrainHQ made by Posit Science) —was found to improve symptoms of hemi-spatial neglect, which is a common and often intractable and debilitating problem after stroke or other acquired brain injury. MedicalResearch.com: What can you tell us about the medical condition (hemi-spatial neglect) investigated in this study? Response About a third of patients with a brain injury exhibit a complex and debilitating array of neurological deficits known as the “neglect syndrome” (sometimes called, “hemi-spatial neglect” or “neglect”). The most apparent symptom of neglect is the inability of patients to efficiently process information on the side of space opposite the injury; often completely missing relevant events without awareness. As a result, patients often fail to adopt compensatory strategies or respond to other conventional rehabilitation protocols. The cost is significant, as patients with neglect experience longer hospital stays and have higher requirements for assistance, including greater skilled nursing home placements relative to patients with similar extent of brain injury without neglect. To date, there’s been no broadly-applicable and highly-scalable intervention for addressing neglect. An alarming reality given the increasing cost of stroke, which is currently estimated to exceed $34 billion per annum (more…)
Author Interviews, Cancer Research, Environmental Risks, University Texas, Urology / 08.05.2019

MedicalResearch.com Interview with: Stephen B. Williams, MD, FACS Chief, Division of Urology Associate Professor, Urology and Radiology Robert Earl Cone Professorship Director of Urologic Oncology Director of Urologic Research Co-Director Department of Surgery Clinical Outcomes Research Program University of Texas Medical Branch at Galveston MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite prior studies evaluating cancer in those living near and working in oil refineries, there remains a gap in knowledge regarding proximity to oil refineries and risk of bladder cancer. Aromatic amines have been associated with increased risk of various cancers including bladder cancer. Texas is a home to the largest numbers of oil refineries in the US. Our goal was to evaluate if there was a link between bladder cancer and living in close proximity to an oil refinery in Texas. Our data did suggest that living within 10 miles of an oil refinery was associated with a small increase in risk of bladder cancer. These data support further research to validate these findings.

Author Interviews / 07.05.2019

MedicalResearch.com Interview with: Lana Zhovtis Ryserson, MD Assistant Professor, Department of Neurology NYU Langone Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Natalizumab is an effective therapy of relapsing remitting multiple sclerosis dosed at 300mg every 4 weeks. However it is associated with a potentially deadly infection - progressive multifocal leukoencephalopathy. In order to mitigate this risk, clinicians have adopted an approach of infusing the medication less frequently, a strategy which has become known as Extended Interval Dosing (EID). The TOUCH database is US mandatated risk evaluation and mitigation program which is the largest database available to assess PML risk for patients on EID schedule. Previous analysis of this database in 2017, showed a significant risk reduction of PML in patients utilizing extended interval dosing schedule. The aim of the current study was to update on this analysis with another year of data. (more…)

MedicalResearch.com Interview with: David Strauss, MD, PhD Director, Division of Applied Regulatory Science U.S. Food and Drug Administration Center for Drug Evaluation and Research MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is unknown whether most active ingredients in sunscreens are absorbed. FDA has provided guidance that sunscreen active ingredients with systemic absorption greater than 0.5 ng/mL or with safety concerns should undergo nonclinical toxicology assessment including systemic carcinogenicity and additional developmental and reproductive studies. This randomized clinical trial demonstrated systemic exposure of 4 commonly used sunscreen active ingredients on application of sunscreen products under maximal use conditions consistent with current sunscreen labeling. All 4 sunscreen active ingredients tested resulted in exposures exceeding 0.5 ng/mL.  (more…)
Author Interviews, Brigham & Women's - Harvard, Education, JAMA / 06.05.2019

MedicalResearch.com Interview with: Arabella L. Simpkin,  MD, MMSc Associate Director, Center for Educational Innovation and Scholarship, MGH Associate Program Director, Education and Curriculum, Internal Medicine Residency, MGH Instructor in Medicine, Harvard Medical School Boston, MA 02114 MedicalResearch.com: What is the background for this study? Response: The academic health care environment has changed in unprecedented ways over several decades, with mounting evidence that faculty are becoming increasingly more unhappy, dissatisfied, and burnt out in their work. Concern for faculty wellbeing is high, with much speculation about causes of burnout. Comprehending what affects satisfaction at work in academic health care centers is critically important to stem this epidemic of discontent. For physicians, satisfaction has been reported to be associated with quality of care delivered, particularly as measured by patient satisfaction; faculty retention and job satisfaction are intricately linked, with dissatisfied physicians more likely to leave the profession and to discourage others from entering. Other industries that have suffered similar rises in employee discontent have found that demonstration of respect is the most important leadership behavior in improving employees satisfaction. To our knowledge this factor has not been looked at in healthcare professionals. To address this gap, we sought to determine key variables influencing satisfaction at work for faculty in a large academic medical center in the United States. (more…)
Author Interviews, CDC, Emergency Care, Occupational Health, Opiods / 02.05.2019

MedicalResearch.com Interview with: Sophia K. Chiu, MD Epidemic Intelligence Service, CDC Division of Surveillance, Hazard Evaluations, and Field Studies National Institute for Occupational Safety and Health CDC  MedicalResearch.com: What is the background for this study? Response:  Responders across the United States are reporting work-related health effects during incidents in which suspected opioids (including fentanyl) and other illicit drugs such as cocaine, methamphetamine, cathinones, and synthetic cannabinoids are present, often as a mixture. These health effects have interfered with responders’ ability to perform their job duties. Since 2018, a number of responder organizations have requested that NIOSH investigate the health effects experienced by emergency responders during these response incidents. These organizations are looking for ways to protect their responders and prevent the symptoms responders have reported experiencing, so that they can in turn better serve the public. NIOSH’s goal is to increase awareness among responders of how they can remain safe while providing the care the public needs. (more…)

MedicalResearch.com Interview with: Nicholas B. DeFelice, PhD Department of Environmental Medicine & Public Health Icahn School of Medicine at Mount Sinai New York, New York MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Effective allocation of public health resources during an outbreak is complicated and often reactive. Thus, it is important that we develop quantitative tools that can accurately and rapidly forecast the progression of an outbreak and provide decision support. Recently, several advancements have been made in the realm of infectious disease forecasting: it is a field that is growing in exciting directions. However, for these forecasting tools to work in real time, we must understand how the forecasting apparatus and observational network work in real time to ensure they are sufficient to support accurate operational predictions. We previously showed that accurate and reliable forecasts of West Nile virus outbreaks can be made using surveillance data and a mathematical model representing the interactions between birds, mosquitoes and risk of human spillover. This model system was able to retrospectively forecast mosquito infection rates prior to the week of peak mosquito infection, and to forecast accurately the seasonal total number of human West Nile virus cases prior to when the majority of cases were reported. For this study, we were interested in the data flow process and the question of whether appropriate infrastructure is in place to support real time forecasting. If this forecast system were made operational in real time, public health officials would have an evidence-based decision-support tool to help 1) actively target control of infected mosquito populations (i.e., larviciding and adulticiding), 2) alert the public to future periods of elevated West Nile virus spillover transmission risk, and 3) identify when to intensify blood donor screening.

Author Interviews, Cancer Research, JAMA, MD Anderson, Radiation Therapy / 30.04.2019

MedicalResearch.com Interview with: Quynh-Nhu Nguyen, MD Department of Radiation Oncology The University of Texas MD Anderson Cancer Center Houston MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This is the first non-spine bone metastases trial comparing higher dose single fraction radiotherapy vs multifraction standard fractionated radiotherapy for patients with painful bone metastases. The results of this trial demonstrated more durable pain relief and superior local control for patients treated in the higher dose(12 Gy-16 Gy)  single fraction RT compared to standard 30 Gy/10 fractions multifractionated regimen.  This trial supports the previous multiple randomized trials which recommend single fraction should be standard palliative radiotherapy regimen for bone metastases.  This trial is unique in that it addressed previous criticism that single fraction does not provide durable palliation with lower 8 gy single fraction and result in higher re-irradiation rates.  This trial on the contrary with the utilization of modern radiotherapy techniques, demonstrated we can safely and more effectively deliver a higher single fraction radiotherapy regimen for improvement in the quality of life for patients.  This higher dose should be the new standard single fraction regimen for patients who are functional and have a longer life expectancy.  (more…)
Addiction, Author Interviews, Cannabis, Pediatrics, Smoking, Tobacco, Tobacco Research / 30.04.2019

MedicalResearch.com Interview with: Joan S. Tucker, Ph.D. Senior Behavioral Scientist RAND Corporation Santa Monica, CA MedicalResearch.com: What is the background for this study?   Response: In light of young adults’ expanding access to cannabis through legalization for recreational use, there has been growing interest in the co-use of cannabis with tobacco/nicotine products.  Although existing data show that young adults who use cannabis products also tend to use tobacco/nicotine products, little is known about how these products are typically used together. Existing research on co-use has mostly focused on combustible products, not accounting for the recent proliferation in cannabis and tobacco/nicotine product types and methods of use (e.g., vaping). Further, not much is known about whether there are important differences between types of co-use (e.g., using both products on the same occasion, one right after another, but not mixing them vs. using both products by mixing them in the same delivery device) in terms of heaviness of use, consequences from use, or associations with young adult functioning. This study was designed as an important first step toward understanding cannabis and tobacco/nicotine co-use behavior among young adults and addressing these gaps in the research literature. (more…)

MedicalResearch.com Interview with: Dr. Joseph A Schwartz PhD Public Affairs and Community Service, Criminology and Criminal Justice University of Nebraska Omaha, Omaha, NE  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: My larger research agenda is focused on identifying the ways in which environmental and biological influences work collectively to shape behavioral patterns across major stages of the life course. I am particularly interested in identifying environmental influences that can change biological functioning or activity to result in behavioral change. Brain injury was a natural progression of these interests since brain injury is expected to result in changes in the structure and functioning of the brain, which has been linked to meaningful changes in behavior. There have also been a sizable number of studies that indicate that justice involved populations experience brain injury at a rate that is between five and eight times what is observed in the general population. I was fascinated by this finding and thought that brain injury may be a good candidate influence to investigate further. (more…)
