MedicalResearch.com Interview with: Ryan J. McLaughlin, PhD Assistant Professor Department of Integrative Physiology & Neuroscience College of Veterinary Medicine Washington State University, Pullman, WA Ryan J. McLaughlin, PhD Assistant Professor Department of Integrative Physiology & Neuroscience College of Veterinary Medicine Washington State University, Pullman, WA MedicalResearch.com: What is the background for this study? Response: The evolving legal landscape concerning the use of cannabis has increased urgency to better understand its effects on the brain and behavior. Animal models are advantageous in this respect; however, researchers traditionally use forced injections of synthetic cannabinoids which fails to capture the complex effects of volitional cannabis consumption. In our study, we developed a novel model of cannabis self-administration using response-contingent delivery of vaporized cannabis extracts containing high concentrations of Δ9 tetrahydrocannabinol (THC) or cannabidiol (CBD).

MedicalResearch.com Interview with: Rafael Maldonado Lopez MD PhD Full professor Departament de Ciències Experimentals i de la Salut Universitat Pompeu Fabra Barcelona MedicalResearch.com: What is the background for this study? Response: Endometriosis is a common, chronic and painful disease caused when the endometrium grows outside of the uterine cavity. These growths mainly affect organs in the pelvis causing pain and infertility, symptoms that are often accompanied with anxiety, depression, loss of working ability, and a substantial impact on quality of life. Current treatments include hormonal therapy and surgery, but the effectiveness of these treatments is rather limited, often have important unwanted side effects, and patients usually rely on self-management strategies. Therefore, there is an urgent need for researching new possible therapeutic approaches.  (more…)
Author Interviews, Cancer Research, Cannabis, End of Life Care, NYU / 28.03.2019

MedicalResearch.com Interview with: Arum Kim, MD Assistant Professor Medicine and Rehabilitation Medicine NYU School of Medicine Director of the Supportive Oncology Program Perlmutter Cancer Center MedicalResearch.com: What is the background for this study?   Response: There is increasing interest in medical marijuana and its applications for patients with cancers. Despite increasing access, little is known regarding doses of cannabinoids - specifically tetrahydrocannabinol (THC)  and cannabidiol (CBD), methods of drug delivery, and differences in patterns of use between cancer and non-cancer patients.

MedicalResearch.com Interview with: Dr. Nicole Karcher, PhD Post-doctoral scholar with the NIMH Training in Clinical Sciences fellowship Department of Psychiatry Washington University School of Medicine   MedicalResearch.com: What is the background for this study? What are the main findings? Response: For over fifteen years, researchers have debated the role that cannabis use plays in the development of both psychotic disorders as well as subthreshold psychotic symptoms, such as psychotic-like experiences (PLEs). There is still a lack of consensus regarding the nature of the association between cannabis use and psychosis risk, with some research finding evidence for genetic overlap, while other research finds evidence for potentially causal pathways. The current study examined data from twins and siblings from two different samples, the U.S.-based Human Connectome Project and the Australian Twin Registry, with a total of 4,674 participants. Overall, psychotic-like experiences were associated with three separate cannabis use variables [frequent (≥100 times) use, a Cannabis Use Disorder diagnosis, and current cannabis use]. Furthermore, the current research found evidence for both shared genetic and individual-specific contributions to the association between PLEs and these three cannabis use variables. More specifically, while the association between cannabis use and psychotic-like experiences was largely attributable to shared genetic factors, cannabis users were more likely to endorse PLEs in comparison to the relative who used cannabis less.  (more…)

David Plurad, MD Los Angeles Biomedical Research In MedicalResearch.com Interview with: David Plurad, MD Los Angeles Biomedical Research Institute. Medical Research: What are the main findings of the study? Based on a survey of patients with traumatic brain injuries, a group of Los Angeles Biomedical Research Institute researchers found those who tested positive for tetrahydrocannabinol (THC), the active ingredient in marijuana, were more likely to survive than those who tested negative for the illicit substance. We surveyed 446 patients who were admitted to a major urban hospital with traumatic brain injuries between Jan. 1, 2010, and Dec. 31, 2012, who were also tested for the presence of THC in their urine. We found 82 of the patients had THC in their system. Of those, 2.4% died. Of the remaining patients who didn't have THC in their system, 11.5% died. While most - but not all - the deaths in the study can be attributed to the traumatic brain injury itself, it appears that both groups were similarly injured. The similarities in the injuries between the two groups led to the conclusion that testing positive for THC in the system is associated with a decreased mortality in adult patients who have sustained traumatic brain injuries.
