Author Interviews, Erectile Dysfunction, JAMA, Karolinski Institute / 23.03.2020

MedicalResearch.com Interview with: Alexander Stridh, MSc Department of Clinical Neuroscience Karolinska Institute Solna, Sweden MedicalResearch.com: What is the background for this study? What are the main findings? Response: ​We wanted to investigate how large the effect size is in the placebo arm of clinical trials with PDE5Is for erectile dysfunction. The major findings in this study is that there is a placebo response in general in ED, though it is hard to tell if this is a genuine placebo effect rather than normal fluctuations in symptom severity among patients. Another interesting finding was that the placebo response seems largely more important when the cause of ED is mainly due to psychogenic factors, as in post traumatic stress disorder. Lastly there was an important finding that there was no difference between placebo and active drug with daily treatment of PDE5Is  for long term recovery of erectile function after prostate cancer treatment, a practice which is common in some places and seems to be questionable.  (more…)
Author Interviews, Coffee / 19.04.2019

MedicalResearch.com Interview with: Eugene Chan, PhD Senior Lecturer in Marketing Monash Business School Monash University Australia and  Sam Maglio PhD Associate Professor of Marketing Department of Management University of Toronto  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The physiological effects of coffee and caffeine consumption have been well-studied, but we were interested in the psychological effects. Especially in Western societies, there is a mental association between coffee and arousal – that coffee is an arousing beverage. This led us to ask, might this association itself produce the psychological “lift” without actually drinking beverages? We found that it does. Merely seeing pictures of coffee or thinking about coffee can increase arousal, heart rates, and make people more focused. The effects are not as strong as actually drinking coffee of course, but they are still noticeable. (more…)
Author Interviews, BMJ, Orthopedics, Pain Research, Surgical Research / 08.02.2017

MedicalResearch.com Interview with: Jonas Bloch Thorlund Associate Professor (MSc, PhD) Department of Sports Science and Clinical Biomechanics Research Unit for Musculoskeletal Function and Physiotherapy University of Southern Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: Arthroscopic partial meniscectomy is a very common knee surgery. Research evidence has seriously questioned the effect of this type of surgery for degenerative meniscal tears in middle-aged and older patients. Most young patients with traumatic meniscal injury (from sports or similar) also undergo this type of surgery. There is a general understanding that young patients with traumatic tears experience larger improvements in patient reported pain, function and quality of life. However, evidence for this presumption is sparse. (more…)

MedicalResearch.com Interview with: Raveendhara R Bannuru MD, PhD, FAGE Director, Center for Treatment Comparison and Integrative Analysis (CTCIA) Asst Professor of Medicine, Tufts University School of Medicine Special & Scientific Staff, Center for Arthritis and Rheumatic Diseases Tufts Medical Center Boston, MA Medical Research: What is the background for this study? Dr. Bannuru: Placebos are used to determine the efficacy of a wide variety of treatments for medical conditions such as osteoarthritis. A sound understanding of potential differences among placebos is essential for determining the relative efficacy of such treatments. Medical Research: What are the main findings? Dr. Bannuru: Our results indicate that different types of placebos do in fact differ in efficacy. Placebo injections and topical placebos were both found to be more effective than orally administered placebos for reducing knee osteoarthritis pain. (more…)

Bret R Rutherford, MD Assistant Professor ,Clinical Psychiatry Columbia University College of Physicians and Surgeons Division of Geriatric Psychiatry New York State Psychiatric Institute New York, NY 10032MedicalResearch.com Interview with: Bret R Rutherford, MD Assistant Professor ,Clinical Psychiatry Columbia University College of Physicians and Surgeons Division of Geriatric Psychiatry New York State Psychiatric Institute New York, NY 10032 Medical Research: What are the main findings of the study? Dr. Rutherford: In this meta-analysis of 105 trials of acute antipsychotic drugs for schizophrenia, the placebo response was shown to be significantly increasing from 1960 to the present. Conversely, the treatment change associated with effective dose medication significantly decreased over the same time period. The average participant of a randomized clinical trial (RCT) receiving an effective dose of medication in the 1960s improved by 13.8 points in the BPRS, whereas this difference diminished to 9.7 BPRS points by the 2000s. The consequence of these divergent trends was a significant decrease in drug-placebo differences from 1960 to the present. (more…)
