MedicalResearch.com Interview with: [caption id="attachment_61672" align="alignleft" width="273"]Roderick J. O’Sullivan Dr. O’Sullivan[/caption] Roderick J. O’Sullivan PhD Associate Professor Department of Pharmacology and Chemical Biology UPMC Hillman Cancer Center University of Pittsburgh Pittsburgh, PA MedicalResearch.com: What is the background for this study? Response: For a few years, my group has had the good fortune of collaborating with Dr. Ivan Ahel. Ivan is a world leader in the field of ADP-ribosylation. His work has identified major gaps in our understanding of ADP-ribosylation. This includes his lab discovering that DNA bases can be ADP-ribosylated in bacteria and that a poorly characterized enzyme known as TARG1 could be involved in that process. In discussing this work with Ivan, we were confident that DNA ADP-ribosylation also exists in human cells and that showing this could be pretty important. The problem was that identifying a part of the genome where it might be present, so we could study it, was not so obvious and challenging. But we had a hunch that telomeres could be one part of the genome where it could happen!! Telomeres are really special structures located at the ends of each human chromosome. They demarcate the physical end of each chromosome and prevent chromosomes from becoming entangled – which if it happens, is catastrophic for cells. Our hunch was based on the evidence from other studies that telomeres are natural targets of PARP1, the enzyme that catalyzes most of the ADP-ribosylation in human cells. I then discussed this idea with Anne Wondisford, a medical scientist trainee in the lab, who liked the idea and designed a series of experiments to test it.

MedicalResearch.com Interview with: [caption id="attachment_61634" align="alignleft" width="150"]Dr Anders HoltDepartment of Cardiology Copenhagen University Hospital–Herlev and Gentofte Gentofte Hospitalsvej Hellerup, Denmark Dr. Holt[/caption] Dr Anders Holt MD PhD Department of Cardiology Copenhagen University Hospital–Herlev and Gentofte Gentofte Hospitalsvej Hellerup, Denmark MedicalResearch.com: What is the background for this study? What types of ADHD treatments were in the study? Response: An increasing number of adults are being diagnosed with ADHD and subsequently treated. Taking the drugs' effect on the sympathetic nervous system into account, it seems relevant to investigate whether treatment could be associated with an elevated long-term risk of cardiovascular disease. The drugs included in the study were methylphenidate, atomoxetine, lisdexamfetamine, dexamfetamine, and modafinil. Owing to the fact that atomoxetine is not a sympathomimetic amine as the others, separate supplementary analyses were carried out for this drug, yielding similar results.

MedicalResearch.com Interview with: [caption id="attachment_61599" align="alignleft" width="150"]Pamela Maher, PhDResearch Professor Cellular Neurobiology Laboratory SALK Institute for Biologic Studies La Jolla California Dr. Maher[/caption] Pamela Maher, PhD Research Professor Cellular Neurobiology Laboratory SALK Institute for Biologic Studies La Jolla California   MedicalResearch.com: What is the background for this study? Response: Several years ago, we tested several different cannabinoids for protection against the oxytosis/ferroptosis regulated cell death pathway and found CBN (cannabinol) to be one of the most effective. While THC (tetrahydrocannabinol) and CBD (cannabidol) were also quite protective, we wanted to pursue non-psychoactive cannabinoids. Since we are interested in maintaining brain function in the context of aging and disease, we thought that a psychoactive compound could be problematic. In addition, there was already a lot of work on CBD, so we thought we could learn more and contribute more to the field by studying CBN.

Response:  Olive oil is rich in monounsaturated fats and contains compounds with antioxidant activity that may play a protective role for the brain. Olive oil as part of a Mediterranean diet appears to have a beneficial effect against cognitive decline. Higher olive oil intake was previously associated with a lower risk of cardiovascular disease and mortality. But its association with dementia mortality was unknown.

MedicalResearch.com Interview with: [caption id="attachment_61647" align="alignleft" width="125"]Sarah Dräger, MDPostdoc, BRCCH Researcher Internal Medicine and ID specialist Division of Internal Medicine University Hospital Basel, Switzerland Basel Dr. Dräger[/caption] Sarah Dräger, MD Postdoc, BRCCH Researcher Internal Medicine and ID specialist Division of Internal Medicine University Hospital Basel, Switzerland Basel   MedicalResearch.com: What is the background for this study? Response:In patients with severe infections and patients in the intensive care unit, therapeutic drug monitoring (TDM) may be used to optimize and personalize intravenous antibiotic treatment. In these patients, “conventional antibiotic dosing”, e.g. selection of the dose only considering the renal function and, if applicable, body weight, may lead to over- or underdosing due to an altered drug metabolism. This, in turn may be associated with worse clinical outcome or toxic side effects. TDM is used to monitor antibiotic blood plasma concentrations and provides guidance to the clinicians to adjust the antibiotic dosing according to the TDM results. But the collection of blood is an invasive, time- and resource-consuming sample collection technique and leads to discomfort to the patients. Additionally, turnaround time may be long (3h to 8h), and analyses may be offered only twice or three time a week. This may be too late to guide antibiotic dosing timely in patients with a very dynamic drug metabolism. Therefore, alternatives are required to overcome the limitations of current TDM. By using exhaled breath, we aim to develop an innovative therapeutic drug monitoring technique, which is non-invasive, easy to collect, not associated with discomfort to the patient, and which may allow to decrease the turnaround time, especially when combined with real-time analyses.

What types of particles, ie where do they come from? Response: This work is a continuation of my research on nanoparticles in consumer products. We have investigated and published on the release of particles from nano-enabled consumer products, such as cosmetic powders, various sprays and clothing. In this project, we were interested in potential resuspension of particles once nano-enabled consumer sprays are used. The particles are added into consumer products to provide them certain desired properties, like antimicrobial protection, odor reduction or protection against UV (sunscreen). Once the products are used, the particles are released and we could be exposed to them.

Would you describe the process of making these neurons? Response: Primary tauopathies are a group of progressive neurodegenerative diseases characterized by the pathological aggregation of 3R or 4R tau protein in neurons and/or glial cells, where 4R tauopathies are more common primary tauopathies. The exact pathological mechanisms remain elusive. There are currently no therapies available that can halt or reverse the spread of tau aggregates since the drug effects found in animal models are not always reproduced in human clinical trials. The development of tau therapies from human cells have become urgently needed. Induced human pluripotent stem cells (iPSCs) offer a unique model to better understand pathological mechanisms underlying human diseases and to develop human cell-based therapy. However, a major challenge to study 4R tauopathy is iPSC-derived neurons express very low levels of 4R Tau isoforms making it difficult to study 4R tauopathy and the mutations located in 4R Tau. To address this need, we designed and engineered a robust human iPSC 4R tauopathy model using CRISPR/Cas9 technology. We first introduced specific mutations at the intron-exon 10 junctions and silent mutations within exon 10 to promote exon 10 inclusion, leading the increase of 4R isoforms expression in iPSC-derived neurons. Frontotemporal Dementia (FTD) mutation, P301S located in exon 10 is highly aggregation prone. To generate this human disease 4R tauopathy model, we then introduced this mutation to 4R iPSC to make it a 4RP301S iPSC line.

MedicalResearch.com Interview with: [caption id="attachment_61615" align="alignleft" width="150"]Gaurav Khanna Ph.D.Assistant Professor | School of Global Policy and Strategy University of California, San Diego Dr. Khanna[/caption] Gaurav Khanna Ph.D. Assistant Professor | School of Global Policy and Strategy University of California, San Diego www.econgaurav.com   MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is a shortage of doctors in certain parts of the US. For instance, although about 20% of the United States population live in rural areas, only 11% of physicians practice in these locations. The research shows that relaxed visa requirements enable more foreign-trained doctors to practice in remote and low-income areas, without reducing the employment of U.S.-trained doctors. One such program that facilitates keeping foreign-born physicians in the US is the Conrad 30 Program. Most participants in the Conrad 30 Waiver Program work in Health Professional Shortage Areas (or HPSAs), areas lacking an adequate number of primary care physicians, dentists, or mental health care providers.

  • Antibiotic resistance, which occurs when germs like bacteria and fungi mutate to defeat the drugs designed to kill them, is a major public health threat.
  • Data show that 40-50% of patients hospitalized with pneumonia receive broad spectrum antibiotics when they do not need them.
  • Helping clinicians tailor antibiotic prescriptions to individual patients can improve patient outcomes by preserving healthy bacteria in the body and reducing the risk of future antibiotic resistance.

Response: Prior studies have found that female and male physicians practice medicine differently. For example, female physicians are, on average, more likely to abide by clinical guidelines and spend more time listening to patients. However, evidence was limited as to whether such differences have clinically meaningful impact on patients’ health outcomes, which was the aim of this study.
Author Interviews, COVID -19 Coronavirus, JAMA, Technology, UCSD, Vaccine Studies / 25.04.2024

MedicalResearch.com Interview with: John W. AyersJohn W. Ayers, PhD MA Vice Chief of Innovation | Assoc. Professor
Div. Infectious Disease & Global Public Health University of California San Diego Since the World Health Organization declared an ‘infodemic’ of misinformation, there have been surprisingly few achievements to celebrate. X's Community Notes have emerged as an innovative strategy to address misinformation as reported in the latest issue of JAMA.
Before the inception of Community Notes, social media companies employed various tactics to tackle misinformation, including censoring, shadowbanning (muting a user or their content on a platform without informing them), and adding generic warning labels to problematic content. However, these efforts were typically undisclosed meaning their effectiveness could not be studied.

In late 2022, X introduced Community Notes. This novel approach empowers volunteer, independent, anonymous, and ideologically diverse contributors to identify posts containing misinformation and to rectify misinformation by appending informative "notes" to suspect posts. The process is controlled by the public, instead of decision-makers at the company. Most importantly the system is open-sourced so it can be studied by external scientists.

Response: Maternal psychopathologies affect a significant number of American women and are the leading complications of childbirth and a significant contributor to maternal death. Maternal (physical) morbidity in the US remain the highest among all countries in the West, suggesting that some women will have a traumatic childbirth experience. The most common mental illness associated with trauma is posttraumatic stress disorder (PTSD). PTSD stemming from childbirth is estimated to affect 6% of delivering women (https://pubmed.ncbi.nlm.nih.gov/28443054/). In high-risk groups, for example women who have unscheduled Cesareans the rate is estimated at 20% or higher (https://pubmed.ncbi.nlm.nih.gov/31041603/.). Although we screen for postpartum depression in hospitals in the USA there is no screening for what we define as childbirth-related PTSD (CB-PTSD). The overarching goal of the Dekel Lab is to develop novel and patient-friendly screening tools to identify women with this disorder. As importantly traumatic childbirth disproportionality affects Black and Latina women (https://pubmed.ncbi.nlm.nih.gov/35598158/).

MedicalResearch.com Interview with: [caption id="attachment_50547" align="alignleft" width="200"]Andrey Vyshedskiy PhD Boston University, Boston Dr. Vyshedskiy[/caption] Dr. Andrey Vyshedskiy, PhD Founder and CEO of ImagiRation LLC Neuroscientist, Boston University MedicalResearch.com: What is the background for this study? Response: The common intuitive belief is that language comprehension development follows a linear trajectory: children acquire one grammatical rule at a time. Over 20 years ago, Dr. A. Vyshedskiy, predicted that instead of linear development, language should unfold in three steps corresponding to three language comprehension mechanisms of increasing complexity. The study of 31845 autistic individuals, published today in the journal npj Mental Health Research, validates this prediction. The implications of this discovery are reaching far and wide. The traditional definition of language is highly ambiguous. For some philosophers, “language” is equivalent to a “communication system.” Others argue that “language” must be defined more narrowly, in a way that is unique to humans. The results of the new study streamline terminology for describing different language comprehension mechanisms. The ensuing discussion of which language comprehension mechanisms are unique to humans and which are shared with other apes is expected to be most interesting.

These patients require additional intervention to avoid potential complications. In the multicenter, randomized AGENT IDE trial, we evaluated whether the AGENT™ Drug-Coated Balloon (DCB), a balloon catheter coated with anti-restenotic paclitaxel, is superior to an uncoated balloon in patients for treating ISR. The AGENT DCB is currently available in countries outside the U.S. Our goal is to bring this technology to market in the U.S. and finally provide physicians with an alternative to traditional ISR treatments, such as placing additional layers of stents or radiation, which may not provide ideal outcomes in some cases. In October 2023, at the Transcatheter Cardiovascular Therapeutics (TCT) 2023 meeting, we presented the primary endpoint data from our AGENT IDE randomized controlled trial evaluating clinical outcomes in patients with ISR undergoing treatment with the AGENT DCB or conventional balloon angioplasty. The positive results in this primary analysis cohort supported the device’s U.S. Food and Drug Administration (FDA) approval, which we announced on March 1, 2024. Just a few months later, data from the full cohort of 600 patients were published in the Journal of the American Medical Association (JAMA) and shared in a late-breaking presentation at Cardiovascular Research Technologies (CRT) 2024 meeting.

Huang, MD, MPH Chancellor's Professor, Infectious Diseases School of Medicine Department of Epidemiology and Infection Prevention University of California Irvine School of Medicine, Irvine MedicalResearch.com: What is the background for this study? Would you describe the decolonization techniques?  
  • This study arose from a growing concern about the increasing number and presence of antibiotic-resistant bacteria causing colonization and infection in hospitals and long-term care. CDC has had a longstanding interest in the value of regional control of these contagious pathogens and they funded this study. The study was actually in two parts:
    • –1) Simulate various infection prevention strategies in a model and see which works best, and then
    • - 2) Do it in real life. The SHIELD project was the real-life example of our simulation finding that decolonization would work the best to prevent harm from antibiotic-resistant bacteria.
  • The regional idea is that it takes all of us working together – hospitals, nursing homes, and long-term acute care hospitals – to prevent the spread and sharing of contagious pathogens. What we can accomplish together is far greater than what any of us can do alone.
  • In this study, decolonization was the use of topical chlorhexidine antiseptic soap and povidone-iodine nasal ointments to reduce potentially harmful bacteria on the body during times when patients and residents may be at risk for infection. We swapped out bathing and showering soap with CHG in participating facilities and ensured that staff knew to clean the body well, including wounds, devices, and rashes where germs can hide and cause infection. For CHG, this involved 4% rinse off product in the shower and 2% no-rinse CHG for bed baths.

Tian, MBSDepartment of Medical Education Geisinger Commonwealth School of Medicine Scranton PA Maria Tian[/caption] Maria Y. Tian, MBS Department of Medical Education Geisinger Commonwealth School of Medicine Scranton PA MedicalResearch.com: What is the background for this study? Response: The antibiotic crisis continues to worsen in the United States (U.S.), which has seen an increasing number of deaths associated with antibiotic resistance, becoming one of the most pressing threats to public health. Concurrently, the availability of effective antibiotics are decreasing, which increases the rates and severity of infections, particularly in patients with respiratory tract infections. Unfortunately, a persistent and pernicious contributing factor to the crisis is the unnecessary prescription of antibiotics. In a previous study, 25% of antibiotics prescribed in the outpatient setting to Medicaid beneficiaries were not associated with a provider visit [2]. Furthermore, among 298 million prescriptions filled by 53 million Medicaid patients between 2004 and 2013, 45% of the prescriptions for antibiotics were made without any clear rationale [2]. In our study, we aimed to provide an up-to-date analysis of antibiotic prescribing in the U.S. through examining the temporal profile of outpatient antibiotic use reported by Medical Expenditure Panel System (MEPS) and geographical patterns of antibiotic prescribing rates among US Medicaid program beneficiaries. This will help identify potentially unnecessary prescriptions and inform stewardship efforts.

Response: Psoriasis is a skin inflammatory disease that affects approximately 2-3% of the population. Previous research had identified that the cytokine IL-17 drives the development of this disease. However, key questions that remained unknown about psoriasis included where did the IL-17 come from, and why do some patients with psoriasis also go on to develop systemic inflammatory conditions such as arthritis. Our research aimed to address these questions using a gain of function (GoF) mouse model that carried a genetic variant in a gene called IKBKB.

Response: Our work was prompted by emerging concerns surrounding the potential nephrotoxic effects of hair-straightening products containing glyoxylic acid. This inquiry was instigated by a patient who experienced three repeated acute episodes of kidney injury in June 2020, April 2021, and July 2022, each occurring shortly after a hair-straightening procedure. Notably, these episodes resolved with hydration. Upon examining the composition of the hair product used by the patient, which contained glyoxylic acid, and considering the patient's report of  painful ulcer scalp during application and subsequent scalp scarring, we suspected a potential link between exposure to glyoxylic acid and kidney injury. Consulting with my colleague, Professor Emmanuel Letavenier, a specialist in crystalline nephropathy at Paris, confirmed this suspicion. In summer 2023, cases series have been reported by an Israeli team (https://pubmed.ncbi.nlm.nih.gov/36610611/), who described 26 patients presenting with acute renal injuries after hair straightening treatments. Biopsies revealed calcium oxalate crystals in the kidneys. The Israeli researchers suspected an effect of formaldehyde and glycolic acid, another substance found in many cosmetic products, including hair straightening products, but were unable to provide conclusive evidence.

Response: Many cancer patients use marijuana to treat pain, nausea, or anxiety, often without communicating this with their health care providers. Two observational studies (1, 2) from a single institution in Israel purporting to find a dangerous drug interaction between medical cannabis and immunotherapy have been cited hundreds of times, including by clinical practice guidelines. The cannabinoid CB2 receptor is found on immune tissues so it is biologically possible that marijuana could make immunotherapies like nivolumab less effective. However, there were anonymous reports on PubPeer (3-5) of many irregularities in the data-analysis. If there were unappreciated differences on other important variables at baseline besides subsequent cannabis use, this could change the interpretation of these influential reports (1, 2). This investigation involved attempting to repeat and verify the data-analysis.

Response: Significant immunological shifts, systemically and at the maternal-fetal interface, are required for a successful pregnancy. Yet, there is a paucity of comprehensive data investigating the systemic immune changes within the same individual transitioning from the non-pregnant to pregnant state.

MedicalResearch.com Interview with: [caption id="attachment_61447" align="alignleft" width="92"]Eric Montminy MDInterventional Endoscopist Cook County Health and Hospitals System Chicago, Illinois Dr. Montminy[/caption] Eric Montminy MD Interventional Endoscopist Cook County Health and Hospitals System Chicago, Illinois   MedicalResearch.com: What is the background for this study? Response: This study was performed in the backdrop of recent colorectal cancer screening guideline updates.  Two national organizations are recommending screening initiation at two different ages: USPSTF recommends initiation at age 45 and the American College of Physicians (ACP) recommends initiation at age 50. With now two national organizations recommending different ages to start screening, patients may become confused (particularly those between 45-50).  Prior confusion has been documented when breast cancer screening recommendations were being changed as well.  Our focus was to examine colorectal adenocarcinoma incidence rates with stage stratification of those who are between the ACP and USPSTF recommendations (ages 46-49). Our study utilized SEER17 data registries over 2000-2020 to collect incidence rates within the U.S.

What are the main findings? Dr. Fangqun Yu: Legionnaires’ disease is a severe form of pneumonia with a fatality rate of 10-25% caused by inhaling or aspirating Legionella, bacteria that thrive in built environment water systems. Those most vulnerable to this disease are male, over 50 years of age, have a history of smoking, have chronic respiratory diseases, diabetes, are immunocompromised, and/or minorities. The US observed a nearly nine-fold increase in Legionnaires’ disease between 2000 and 2018, with New York State having one of the highest increases in disease rates. The reasons for the increase in incidence were unclear prior to this study. In our study, we found: (1) Declining sulfur dioxide concentrations (SO2) are strongly correlated with the increase in legionellosis cases and a physical mechanism explaining this link is proposed, (2) A geostatistical epidemiological analysis links the disease with exposure to cooling towers, and (3) Climate and weather are ruled out as factors responsible for the long-term increase in case numbers (outside of seasonal trends).

MedicalResearch.com Interview with: [caption id="attachment_61434" align="alignleft" width="150"]Mukundan G. Attur, PhDAssociate Professor, Department of Medicine NYU Grossman School of Medicine Dr. Attur[/caption] Mukundan G. Attur, PhD Associate Professor, Department of Medicine NYU Grossman School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response:  The study investigates the potential protective effects of a genetic variant of IL1RN against inflammation and severe outcomes, particularly in COVID-19. Previous research indicates that carriers of this genetic variant may experience less severe radiographic knee osteoarthritis and decreased inflammation in rheumatoid arthritis patients. Given the emergence of cytokine release syndrome in COVID-19 patients, the researchers sought to understand whether the same genetic variant could offer protection against inflammation and potential death in COVID-19 cases.
