MedicalResearch.com Interview with: Rebecca Arden Harris, MD, MSc Assistant Professor of Family Medicine and Community Health at the Hospital of the University of Pennsylvania Senior Fellow, Leonard Davis Institute of Health Economics Perelman School of Medicine, University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: The impact of the nationwide overdose epidemic on Black women has received little attention from policy-makers, researchers, or the press. MedicalResearch.com: What are the main findings? Response:  Over the 7-year study period, preventable overdose deaths among Black women resulted in nearly 0.75 million years of life lost (YLL). Women aged 25-34 have suffered a rising proportion of this burden. (more…)
Addiction, Author Interviews, Pain Research / 01.12.2022

  MedicalResearch.com Interview with: Lavinia Harrison Geisinger Commonwealth School of Medicine Scranton, PA  18509 MedicalResearch.com: What is the background for this study? Response:   The opioid meperidine (Demerol) was widely prescribed in the United States (US) as an analgesic to treat moderate to severe pain. Meperidine was the most used opioid in the US in 1987 and was considered safer than other opioids during acute pancreatitis. Over the past two decades, meperidine has shifted from being frequently prescribed to being used only when patients are experiencing atypical reactions to opioids (e.g., morphine and hydromorphone); to removal from the World Health Organization's essential medication list and receiving strong warnings against its use from many professional organizations including the American Geriatrics Society. The unfortunate Libby Zion (1965-1984) case increased concerns about serotonin syndrome with meperidine. According to a prior pharmacoepidemiology report, the distribution of meperidine in the United States decreased by 95% between 2001 and 2019 [1]. The aim of the study was to include updated information (2020 and 2021) as well as examine the changes among Medicaid patients [2]. (more…)

MedicalResearch.com Interview with: Mitchell Wong, MD PhD Professor of Medicine Executive Vice Chair for Research Training Department of Medicine Executive Co-Director, Specialty Training and Advanced Research (STAR) Program Director, UCLA CTSI KL2 Program UCLA Division of General Internal Medicine and Health Services Research Los Angeles, CA 90024 MedicalResearch.com: What is the background for this study? Response: It is estimated that social factors like poverty, education, and housing have a large impact on health. Yet, there are few interventions that exist to directly address those issues.  Schools are a promising solution since society already invests heavily in education and schools are an everyday part of most children’s lives.

Addiction, Author Interviews, Methamphetamine / 02.09.2022

Methamphetamine is a highly addictive stimulant drug that is often used recreationally. It is a central nervous system (CNS) stimulant used to treat ADHD and narcolepsy. The drug is highly addictive and should be used only under the supervision of a healthcare provider. Meth mouth is a slang term used to describe the dental problems resulting from methamphetamine abuse. The long-term use of methamphetamine can lead to meth mouth due to the detrimental effects the drug has on oral health. What Are the Signs of Meth Mouth? The signs of meth mouth can vary depending on the severity of the condition. However, some common signs and symptoms of meth mouth include:
  • Severe tooth decay
  • Tooth loss
  • Missing teeth
  • Broken teeth
  • Cracked teeth
  • Yellow or brown stains on teeth
  • Gum disease
  • Dry mouth
  • Bad breath
  • Meth sores

MedicalResearch.com Interview with: Bryan Roth, MD, PhD Michael Hooker Distinguished Professor Pharmacology Director, NIMH Psychoactive Drug Screening Program Eshelman School of Pharmacy Gavin P. Schmitz Department of Pharmacology University of North Carolina at Chapel Hill School of Medicine Chapel Hill, North Carolina   Department of Pharmacology, School of Medicine University of North Carolina at Chapel Hill Chapel Hill, North Carolina MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: There is undoubtably a lot of enthusiasm for psychedelics as therapeutic tools right now both in research and more broadly; however, there are still so many questions that need to be answered. It has been established that SNPs are clinically relevant when considering how patients may respond to various atypical antipsychotic drugs, so we wanted to see if they also could impact psychedelic assisted treatment strategies. What we found is that genetics do matter; namely, our results indicate that patients with different genes will react differently to psychedelics. (more…)
Addiction, Author Interviews, Opiods / 07.06.2022

MedicalResearch.com Interview with: Colleen G. Jordan, MBS Department of Medical Education Geisinger Commonwealth School of Medicine MedicalResearch.com: What is the background for this study? Response: Opioid addiction and misuse remain a prevalent issue in the United States (U.S.). There have been more than one-million drug overdoses in the U.S. since 1999 [1], largely driven by opioids, which exacerbate the strain on resources in hospitals, treatment centers, first responders, patients, and their families. The existing pharmacotherapies for opioid use disorder (OUD) are not working. Naloxone is a competitive mu opioid receptor antagonist used to reverse respiratory and CNS depression in those experiencing an opioid overdose but requires further dosing to prevent subsequent overdose. Naltrexone is a competitive mu opioid receptor antagonist, and has extended-release formulations intended to reduce relapse and promote adherence, yet patient noncompliance and retention continue to be limiting factors. Methadone is commonly used to treat opioid addiction as a replacement for illicit opiates but is itself an addictive substance which can result in overdoses [2] and can lead to withdrawal if not closely monitored by a licensed professional. Buprenorphine is currently used to treat opioid use disorder (OUD), and while it reduces illicit drug use, it is less effective than methadone for retaining patients in treatment. For these reasons, there is an urgent need for new opioid misuse interventions. The objectives of this study [3] were to understand the implications of OUD and overdose treatments and determine the strengths and shortcomings of current treatments in comparison with the novel drug candidate methocinnamox (MCAM). These were completed through an extensive literature review into the history of the opioid epidemic in the United States, opioid receptors in the brain, current pharmacological treatments, and the pharmacological properties of MCAM.

Addiction, Author Interviews / 17.02.2022

MedicalResearch.com Interview with:

Harriet De Wit, PhD Professor of Psychiatry and Behavioral Neuroscience University of Chicago 

MedicalResearch.com:  What is the background for this study?    Response: There are numerous reports that psychedelics like LSD, taken in very small ‘microdoses’, help boost mood, cognitive function and productivity. The practice is popular in Silicon Valley and among media figures, who report remarkable beneficial effects from regular use of these microdoses. The possible antidepressant effects of LSD are plausible from a neurobiological perspective, as the drug acts directly on serotonin receptors, the same systems where SSRI’s act.  However, the effects of microdosing have not yet been validated in controlled research. In our study, we recruited healthy men and women to ingest repeated, low doses of LSD under double blind conditions.  They attended four laboratory sessions, separated by three to four days.  They were randomly assigned to one of three groups who received the same drug on all four sessions: placebo, 13 micrograms of LSD or 26 micrograms of LSD. Subjects were not told exactly what drug they were receiving until the end of the study.  We measured their mood, emotional reactivity and cognition. (more…)

MedicalResearch.com Interview with: Dr. Laurence Moss MD, PhD candidate Centre for Human Drug Research (CHDR) Department of Anesthesiology Leiden University Medical Centre (LUMC) Geert Jan Groeneveld​, MD, PhD Neurologist | Clinical Pharmacologist | Professor of Clinical Neuropharmacology CMO/CSO Centre for Human Drug Research Leiden, The Netherlands  MedicalResearch.com:  What is the background for this study?    Response: Opioid use disorder (OUD) is a major source of morbidity and mortality, and the opioid epidemic in the Unites States (but increasingly in Europe also) has been well documented and reported on by the media. The alarming rise in opioid related mortality is largely driven by the increasing use of fentanyl and fentanyl analogues, often surreptitiously mixed with heroin or other drugs such as psychostimulants or prescribed opioids. Opioid-induced respiratory depression in particular is a leading cause of opioid-related fatalities. Buprenorphine has been proven as an effective medication for the treatment of OUD. Buprenorphine is a semi-synthetic partial agonist for the opioid receptor that firmly binds to these receptors and displays only partial respiratory depressive effects, meaning it does not cause the complete cessation of breathing as is the case with other potent opioids such as fentanyl. Due to its firm receptor binding, we hypothesized that at sufficient buprenorphine receptor occupancy, the effect of fentanyl on respiration would be limited, even at high fentanyl doses. This study aimed to provide proof of principle for this hypothesis, and demonstrate whether buprenorphine could reduce fentanyl-induced respiratory depression. (more…)

MedicalResearch.com Interview with: Daniel Myran, MD, MPH, CCFP, FRCPC Family and Public Health and Preventive Medicine Physician CIHR Fellow, Ottawa Hospital Research Institute Department of Family Medicine Innovation Fellow University of Ottawa MedicalResearch.com: What is the background for this study? Response: Canada legalized recreational, or non-medical, cannabis in October 2018. Canada took phased approach to legalization initially only allowing flower-based cannabis products and oils and after one year permitting the sale of commercial cannabis edibles (e.g. THC containing candies, baked goods, and drinks). In this study we took advantage of this phased roll out of legal cannabis to understand the impact of legalization on cannabis exposures or poisonings in children aged 0-9 years and the contribution of different types of cannabis products to these events.

MedicalResearch.com Interview with: Julie O’Donnell, PhD MPH Division of Overdose Prevention National Center for Injury Prevention and Control CDC National Network of Public Health Institutes New Orleans, Louisiana MedicalResearch.com: What is the background for this study? Response: The estimated number of drug overdose deaths in the US surpassed 100,000 over a 12-month period for the first time during May 2020-April 2021, driven by the involvement of synthetic opioids other than methadone (mainly illicitly manufactured fentanyl (IMF)), according to data from the National Vital Statistics System. The State Unintentional Drug Overdose Reporting System (SUDORS) is a CDC-funded surveillance program that has collected detailed data on unintentional and undetermined intent drug overdose deaths since 2016 from death certificates, medical examiner and coroner reports, and full postmortem toxicology reports. SUDORS data allow for the analysis specifically of deaths involving fentanyl (rather than the larger category of synthetic opioids), and contain information about decedent demographics and other characteristics, as well as circumstances surrounding the overdose that might help inform prevention.

MedicalResearch.com Interview with: Rayyan Raja Zafar BSc. MSc. MRSB. Medical Research Council Doctoral Training Partnership (MRC DTP) PhD Candidate Centre for Psychedelic research & Neuropsychopharmacology Division of Psychiatry Department of Brain Sciences, Faculty of Medicine Professor David Nutt DM, FRCP, FRCPsych, FSB, FMedSci Faculty of Medicine, Department of Brain Sciences The Edmond J Safra Chair in Neuropsychopharmacology Imperial College London MedicalResearch.com: What is the background for this study? Response: Since 2018 medical cannabis prescription has become legal in the UK for patients to access. In spite of this legal change less than 3 NHS prescriptions have been made available and access to whole-plant medical cannabis products has been restricted largely to private prescriptions with very few clinicians prescribing such products. There has been a lot of anecdotal and real world evidence of the value of whole-plant medical cannabis in children suffering with treatment resistant epilepsy. (more…)

MedicalResearch.com Interview with: Ashish Thakrar, MD Internal Medicine & Addiction Medicine National Clinician Scholars Program University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: About 1.8 million Americans are currently incarcerated, more than any other country in the world per capita. Of those 1.8 million, about 1 in 7 suffers from opioid addiction, putting them at high risk of overdose and death, particularly in the weeks following release. Opioid use disorder is a treatable condition, particularly with the medications buprenorphine or methadone, but historically, prisons and jails have not offered treatment. Over the past five years, a few states and municipalities have enacted policies to provide access for OUD treatment. We examined whether these policies were actually improving access to treatment.  (more…)
Author Interviews, Cannabis, Fertility / 30.11.2021

MedicalResearch.com Interview with: Kanako Hayashi PhD Associate Professor Associate Director, Center for Reproductive Biology Washington State University MedicalResearch.com: What is the background for this study? Response: There have been several correlative reports showing statistical associations between cannabis use and low sperm counts, dysregulated menstruation, abnormal placentation, preterm birth, stillbirth and offspring psychosis etc. However, the long-term consequences of cannabis use on reproductive functions and how it might impact the next generation have not been examined. In the present study, we examined the generational effects of cannabis vapor exposure on male reproductive function. Vaporization is the most common route of cannabis administration in humans. Therefore, in order to understand the generational effects of cannabis exposure on male reproductive functions, the present study was performed using an inhalation method as an administration route, by which adult male mice were exposed to dry cannabis plants to assess the toxicological effects of cannabis on F0, F1 and F2 male reproductive functions.

MedicalResearch.com Interview with: Jeffrey Howard, PhD Associate Professor Department of Public Health College for Health, Community and Policy University of Texas at San Antonio MedicalResearch.com: What is the background for this study? Response: Drug and alcohol related mortality has been on the rise in the US for the past decade, which has drawn a lot of focus from researchers.  At the same time maternal mortality, deaths caused by pregnancy complications, is recognized to be higher in the US than in other developed nations. Very little has been reported about deaths among pregnant and recently pregnant women that are not caused by pregnancy complications, so my collaborators and I wanted to explore this.  We did not anticipate that drug and alcohol deaths and homicides would account for so many deaths among pregnant and recently pregnant women.

MedicalResearch.com Interview with: Carmen Lim BSc(Hons), MSc, CStat PhD Candidate National Centre for Youth Substance Use Research Faculty of Health and Behavioural Sciences The University of Queensland Brisbane Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: This review has systematically summarized the trends and products used for cannabis vaping using 17 studies published globally between Jan 1, 2003 and August 19, 2020. The pooled prevalence has increased for lifetime use (6.1% in 2013 to 13.6% in 2020), past-year use (7.2% in 2017 to 13.2% in 2020) and past-month use (1.6% in 2013 to 8.4% in 2020). Adolescents' preference for cannabis products may be shifting from less potent products (e.g., herbal cannabis) to highly potent vape oil and concentrates. (more…)

MedicalResearch.com Interview with: Beth Han, M.D., Ph.D., M.P.H. Epidemiologist, Science Policy Branch of the National Institute on Drug Abuse (NIDA), National Institutes of Health MedicalResearch.com: What is the background for this study? Response: In the U.S., overdose deaths involving psychostimulants with abuse potential other than cocaine (i.e. largely methamphetamine), increased dramatically during the past decade. Psychostimulant-involved overdose deaths also often involved opioids (50% in 2017). However, it was still undetermined how trends in methamphetamine use among vulnerable populations and specific patterns of use [e.g. methamphetamine use with or without other substances, frequent methamphetamine use, methamphetamine use disorder (MUD), and injection] may contribute to greater risk for overdose mortality. Moreover, understanding characteristics that are associated with methamphetamine use, frequent use, MUD, and injection is of value in guiding strategies to address the root causes for the recent surge in methamphetamine overdose deaths.

MedicalResearch.com Interview with: Andres Zorrilla Vaca, MD Resident Physician Brigham and Women’s Hospital Boston, Massachusetts  MedicalResearch.com: What is the background for this study? Response: The background for this study was Enhanced Recovery After Surgery, also known as ERAS protocols. They basically consisted of a bundle of interventions that are performed preoperatively, intraoperatively and postoperatively with the aim of enhancing patient recovery and reducing complications. This protocol in our institution started with a thorough preoperative counseling which includes, smoking cessation, pain and analgesia education, ERAS program expectations, pulmonary rehabilitation based on pulmonary function tests and incentive spirometry. On the day of surgery, prolonged fasting is avoided and a carbohydrate loading is given orally 2 hours before surgery. Our protocol also included a standardized multimodal analgesic regimen consisting of tramadol ER 300mg p.o. and gabapentin 300mg p.o., intraoperative acetaminophen 1gm i.v., posterior intercostal nerve blockade with liposomal bupivacaine 266mg prior to incision, intraoperative 30mg ketorolac upon wound closure and scheduled postoperative acetaminophen 1g p.o. q 6hrs and ketorolac 15mg i.v. q 6 hrs, as well as additonal interventions recommended by ERAS Society Guidelines. As a general rule, preoperative sedatives (midazolam) are avoided as premedication and prophylaxis against nausea and vomiting (ondansetron, dexamethasone and scopolamine) is administered. Patients are kept euvolemic by using validated goal-directed fluid therapy algorithms (stroke volume variation and cardiac output) and normothermia is maintained throughout the procedure. (more…)

MedicalResearch.com Interview with: Sam Craft Addiction and Mental Health Group (AIM), Department of Psychology, University of Bath, Bath National Addiction Centre, Institute of Psychiatry, Psychology and Neuroscience King’s College London, London UK MedicalResearch.com: What is the background for this study? Response: Synthetic cannabinoid receptor agonists (SCRAs, also known as Spice or K2) are a group of synthetic drugs originally produced to mimic the effects of cannabis. As they are often more accessible or cheaper and cannot be detected on drugs tests, SCRAs may be used as an alternative to cannabis. However, although they act on the same receptors – cannabinoid receptor type 1 and 2 (CBR1; CBR2) – SCRAs are far more potent than cannabis which may make them more addictive and increase the severity of withdrawal (unpleasant symptoms experienced after cessation of a drug which has been used in large amounts for a long period of time) As part of the Global Drug Survey, in this study we asked participants who use both SCRAs and cannabis to compare their effects across different measures which indicate how likely a drug is to result in long-term harm. For example, how severe withdrawal symptoms are and how long the effects last. We also asked participants which withdrawal symptoms they experienced when attempting to stop.  (more…)
Addiction, Author Interviews, Opiods, Race/Ethnic Diversity / 10.09.2021

John A. Furst BS Geisinger Commonwealth School of Medicine MedicalResearch.com: What is the background for this study? Response: Methadone is an evidence-based pharmacotherapy for opioid detoxification, maintenance therapy, and pain management. However, accessibility of this treatment remains variable across much of the country. Methadone for the treatment of opioid use disorder (OUD) is exclusively provided by federally regulated opioid treatment programs (OTPs) and has provoked significant community-based and legal controversy regarding its role in the management of this condition. This has created disparities related to the distribution and access of methadone throughout the United States (U.S.). The goal of this study1 was to highlight the most recent pharmacoepidemiologic trends associated with methadone in the face of unique restrictions at the local, state, and federal levels. (more…)

MedicalResearch.com Interview with: Mark Anderson, Ph.D. Associate Professor Department of Agricultural Economics and Economics Montana State University, IZA, and NBER  MedicalResearch.com: What is the background for this study? Response: In a previous study that was published in JAMA Pediatrics, we used Youth Risk Behavior Survey (YRBS) data and found that the adoption of recreational marijuana laws (RMLs) was associated with an 8% decrease in the odds of marijuana use among high school students.  This earlier study, however, had pre-legalization and post-legalization data from only 7 states and pre- and post-recreational sales data from only 3 states, calling into question the generalizability of our findings.

Addiction, Author Interviews, Cocaine, Pain Research / 18.08.2021

MedicalResearch.com Interview with: Youngeun Armbuster Geisinger Commonwealth School of Medicine Scranton, Pennsylvania MedicalResearch.com: What is the background for this study? Response: Cocaine is classified by the U.S. Drug Enforcement Administration (DEA) as a Schedule II drug that can be used as an anesthetic in various types of surgery by otorhinolaryngologists, as well as in diagnosing Horner syndrome. Although controlled doses of cocaine used in topical anesthetics does not cause myocardial infarction as can occur with recreational dosages, intranasal administration of cocaine is absorbed systemically and it results in vasoconstriction of the coronary arteries via stimulation of adrenergic receptors. These potential adverse effects may disincentivize health care providers from medical cocaine use. Our objective was to quantify the trends in licit cocaine distribution in the United States using DEA data and to determine the usage of medical cocaine in Medicaid and Medicare, as well as based on electronic medical records [1].

MedicalResearch.com Interview with: Joy M. Schmitz, Ph.D. Professor of Psychiatry Faillace Chair McGovern Medical School The University of Texas Health Science Center at Houston Director, Center for Neurobehavioral Research on Addiction (CNRA)   Scott D. Lane Ph.D. McGovern Medical School Vice Chair For Research Director Of Neurobehavioral Laboratory Center For Neurobehavioral Research On Addiction Director Of Research University of Texas Health Science Center at Houston Houston, TX  MedicalResearch.com: What is the background for this study? Response: Addiction science has made considerable progress in understanding how cocaine and other addictive drugs impair the brain. Over time, cocaine can disrupt brain regions that help us think, plan, solve problems, and exert self-control. These disruptions in brain structure can be seen in neuroimaging studies that reveal impairment in the nerve fibers or white matter (WM) tracts in the central and front parts of the brain. We conducted two systematic meta-analytic reviews of the literature to document the robustness of evidence showing alterations in WM integrity of chronic stimulant users relative to healthy control subjects who did not use cocaine or other drugs of abuse (Beard et al., 2019; Suchting et al., 2020). Importantly, WM impairments negatively predict treatment outcome, meaning individuals with greater levels of WM impairment are less likely to benefit from treatment and more likely to experience deficits in attention, working memory, and impulse control. We reasoned that pharmacological interventions shown to protect WM integrity may help improve cognition and treatment outcomes in patients recovering from cocaine addiction. Pioglitazone, an approved medication for type 2 diabetes, has been shown to reduce inflammation and mediate protection after traumatic brain injury. The therapeutic potential of pioglitazone has prompted investigation of its role in neurodegenerative conditions, such as dementia, Alzheimer’s disease, and stroke. Similar to these brain diseases and injuries, pioglitazone might effectively protect the brain from the inflammatory damage created by cocaine use.  (more…)

MedicalResearch.com Interview with: John Boyle, BS Department of Medical Education Geisinger Commonwealth School of Medicine MedicalResearch.com: What is the background for this study? Response:  Meperidine is an opioid analgesic which has been approved for use since the 1940s for moderate to severe pain. During the 1990s, concerns about adverse effects (e.g., serotonin syndrome) and CYP450 drug interactions (e.g., 3A4 inhibition of other metabolism of other common medications) were raised and by 2003 it was removed from the WHO’s List of Essential Medicines. Despite increased awareness of adverse effects, meperidine is still used in the United States. It was the goal of this study1 to uncover pharmaepidemiological trends in its use. (more…)
