MedicalResearch.com Interview with: Dr. Janarthanan Sathananthan M.D. Chief Medical Officer for Interventional Cardiology Therapies Boston Scientific MedicalResearch.com: What is the background for this study? boston-scientificResponse: Despite significant improvements in the drug-eluting stents that are used to treat patients with coronary artery disease, 10% of the percutaneous coronary interventions (PCIs) in the U.S. today address in-stent restenosis (ISR), which is when a previously stented section of a coronary artery becomes obstructed or narrowed by plaque or scar tissue. 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.  (more…)
Author Interviews, Radiology / 02.04.2024

When a person visits a doctor, they might find tests are needed to determine the cause of problems they are experiencing. Countless tests might be used based on the symptoms the person is experiencing. However, some tests remain very common today. The following are the ones that a doctor might recommend. Biopsy One of the best health care diagnostic tests for suspicious lumps is a biopsy. During this procedure, the doctor removes one or more tissue samples from the body to examine them. They use this test to determine whether a patient has cancer, bone marrow issues, or other health issues. Colonoscopy Doctors request a colonoscopy when they suspect a patient has problems with their large intestine or rectum. They insert a flexible tube with a tiny camera in the tip into the rectum to view changes in the intestine or rectum. If they see suspicious areas, a biopsy can be taken for further testing. (more…)
Author Interviews, CDC, Infections, JAMA / 01.04.2024

MedicalResearch.com Interview with: Susan S. 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.

Author Interviews, Infections / 01.04.2024

MedicalResearch.com Interview with: 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. (more…)

MedicalResearch.com Interview with: Jay P. Solgama Medical Student Department of Medical Education Geisinger Commonwealth School of Medicine Scranton PA   MedicalResearch.com: What is the background for this study? Response: The opioid crisis in the United States continues to escalate, with opioid-related deaths increasing by over 800% since 2000. Prescription opioids, particularly oxycodone, have been a contributor to this crisis, with substantial variations in their distribution observed across different states [1,2,3]. Against this backdrop, the study conducted by researchers from the Geisinger Commonwealth School of Medicine aimed to characterize the distribution of oxycodone across US states from 2000 to 2021. By analyzing data from the Drug Enforcement Administration’s comprehensive Automation of Reports and Consolidated Orders System (ARCOS) and the Centers for Disease Control and Prevention Wide-ranging ONline Data for Epidemiologic Research (WONDER) databases, the study sought to identify trends and patterns in oxycodone distribution and their potential implications for opioid-related deaths [4,5].

MedicalResearch.com Interview with: Chelisa Cardinez PhD Postdoctoral Researcher The Burr Laboratory- Cancer Immunology and Epigenetics Genome Sciences and Cancer Division The John Curtin School of Medical Research The Australian National University Canberra, Australia   MedicalResearch.com: What is the background for this study? 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. (more…)
Author Interviews, Dermatology, Kidney Stones, NEJM / 28.03.2024

MedicalResearch.com Interview with: Thomas Robert, MD, AIX Associate Professor of Nephrology APHM (Assistance Publique - Hopitaux de Marseille) Marseille, Provence-Alpes-Côte d'Azur, France   Prof. Emmanuel Letavernier, MD PhD Nephrologist at Tenon Hospital Paris, France MedicalResearch.com: What is the background for this study? 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.

MedicalResearch.com: What is the background for this study? Response: Child abuse and neglect is a serious problem that affects too many kids and teens across the United States. This type of maltreatment can have a profound effect on their health, development, and well-being, both when they are young and into adulthood. (more…)
Alzheimer's - Dementia, Author Interviews, JAMA, UC Davis / 25.03.2024

MedicalResearch.com Interview with: Charles DeCarli, MD, FAAN, FAHA Victor and Genevieve Orsi Chair in Alzheimer's Research Distinguished Professor of Neurology Director, Alzheimer's Disease Research Center and Imaging of Dementia and Aging (IDeA) Laboratory Department of Neurology and Center for Neuroscience University of California at Davis Sacramento, CA  95817   MedicalResearch.com: What is the background for this study? Response: The overall health of the U.S. population has improved dramatically over the last 100 years, Individuals are also living longer resulting in an increasing percentage of the population at risk for Alzheimer’s disease and related dementias (ADRD).  Recent data from the Framingham Heart study, however, finds that dementia incidence may be declining.  While many factors such as greater educational achievement and medical management of vascular risk factors may explain part of this effect, early life environmental differences also likely contribute.

MedicalResearch.com Interview with: Steven S. Raman, M.D., FASR, FSIR Professor of Radiology, Urology and Surgery David Geffen School of Medicine UCLA MedicalResearch.com: What is the background for this study? Would you describe the TULSA technique? Response: Prostate cancer is the most common solid organ cancer in men.  Currently whole gland ablation relies on surgery or radiation both of which have high rates of impotence and incontinence but also have up to a 30% rate of post therapy recurrence. TULSA is a new minimally invasive technique to treat PCa under MRI guidance with both near continuous whole gland MRI imaging and MRI thermometry to make sure the extent of lethal heating over 55 degrees Celsius is known.  (more…)
Addiction, Author Interviews, Cancer Research, Cannabis / 23.03.2024

MedicalResearch.com Interview with: Brian J. Piper, PhD Associate Professor of Neuroscience Geisinger Commonwealth School of Medicine Scranton PA 18411 MedicalResearch.com: What is the background for this study? 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. (more…)

MedicalResearch.com Interview with: Chelsea A DeBolt, MD Assistant Professor, Obstetrics, Gynecology and Reproductive Science Division of Maternal-Fetal Medicine Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? 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. (more…)
Author Interviews, Brigham & Women's - Harvard, Infections, JAMA, Multiple Sclerosis, Neurological Disorders / 19.03.2024

MedicalResearch.com Interview with: Marianna Cortese, MD, PhD Senior Research ScientistDepartment of Nutrition Harvard T.H. Chan School of Public HealthBoston, MA 02115   MedicalResearch.com: What is the background for this study? Response: In a study published in Science in 2022, we reported compelling evidence that infection with the Epstein-Barr virus is the leading cause of Multiple Sclerosis. This is a follow-up study to investigate more in depth whether the antibody response to EBV is distinct in individuals with MS compared to individuals without MS and whether there is a part of EBV that the immune response is particularly targeting. For this purpose we assessed the immune response to all protein parts (peptides) of EBV and their association with MS. Previous studies could only look at parts of EBV and this is the first study looking at all EBV peptides. Antibodies to EBV (especially to a protein called EBNA1) are known to be overall higher in individuals with MS, so we also tested whether immune response overall or the immune response to specific EBV protein parts was more important. If the immune response to a specific EBV protein part (peptide) would be standing out or distinguishing individuals with MS, we hypothesized, it could point to a specific mechanism of how EBV may cause MS, i.e. it could point for example towards “molecular mimicry”, which is when antibodies targeting a pathogen start targeting a body-own structure (for example in the brain) which resembles the protein parts of the pathogen.

Author Interviews, Colon Cancer, JAMA / 19.03.2024

MedicalResearch.com Interview with: 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.  (more…)

MedicalResearch.com Interview with: Dr. Fangqun Yu PhD Senior Research Faculty Atmospheric Sciences Research Center University Albany, State University of New York https://www.albany.edu/~yfq   Dr. Arshad Arjunan Nair PhD Postdoctoral Associate Atmospheric Sciences Research Center University at Albany, State University of New York https://www.albany.edu/~an688965   MedicalResearch.com: What is the background for this study? 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).

Author Interviews, COVID -19 Coronavirus, Infections, NYU / 14.03.2024

MedicalResearch.com Interview with: 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.

Author Interviews, Sleep Disorders / 12.03.2024

MedicalResearch.com Interview with: Soomi Lee, PhD Associate Professor | Department of Human Development and Family Studies | Center for Healthy Aging Director of STEALTH Lab: https://sites.psu.edu/stealth/ The Pennsylvania State University MedicalResearch.com: What is the background for this study? Response:  Sleep quantity and quality decline with advancing age; a risk of chronic conditions also increases with age. While previous studies report that poor sleep is a significant risk for chronic conditions, many have focused solely on a single dimension of sleep, such as duration, thereby limiting the ability to assess multiple co-occurring dimensions and their associations with chronic conditions. This study aimed to evaluate multiple dimensions of sleep health, including regularity, satisfaction, alertness, efficiency, and duration. By analyzing data from a national sample of adults (n=3,683) collected over two time points spanning a decade, the study identified four distinct sleep health phenotypes: good sleepers, insomnia sleepers, weekend catch-up sleepers, and nappers.

Author Interviews / 09.03.2024

Precision in healthcare isn't just important; it's an absolute non-negotiable. Consider how anxiety-inducing a world where health information wasn't treated with absolute care, accuracy, and precision would be. Transcription, the process of converting spoken words into written text, is indispensable to the medical world. Medical scribes transcribe by recording important details of physician-patient encounters, while clinical researchers must convert their findings into analysable written text to ensure their validity and create opportunities for further learning and understanding of their results. So, let's explore six main ways transcription supports the precision and integrity of healthcare.

Enhancing Accuracy and Precision

medical-scribes-dictationSkilled medical scribing entails meticulous transcription of patient encounters, procedures, or treatment plans from spoken word into written text, capturing every detail and nuance. Transcription is a pivotal tool for ensuring that the physician follows the proper procedure and that medical records, reports, and documentation have perfect levels of accuracy. Medical scribing is a skilled profession that requires solid knowledge of the worker's chosen healthcare field. Any misinterpretation of patient information has the potential to lead to ill-informed future decisions regarding a patient's health. Healthcare organisations must also adhere to strict guidelines regarding the documentation of patient care, billing processes, and confidentiality protocols. Skilled medical scribes with specialised knowledge and expertise in their industry can protect organisations from costly lawsuits and ensure that patients are treated with the correct level of integrity. In today's world, time is money. Successful medical scribes improve efficiency and take the burden off physicians having to personally record data, enabling them to see more patients and listen more attentively, ultimately contributing to reaching the healthcare company's overall productivity and financial aims. One study found that medical scribes cut costs by $31.15 per hour, with no risk added risk to patient safety. (more…)
ADHD, Author Interviews, Dermatology, JAMA, Mental Health Research / 08.03.2024

MedicalResearch.com Interview with: Dr. Joy Wan M.D., M.S.C.E. Assistant Professor of Dermatology Johns Hopkins University School of Medicine MedicalResearch.com: What is the background for this study? Response: There has been a growing body of literature linking atopic dermatitis with diagnoses such as ADHD and learning disabilities, but studies focusing on symptoms of cognitive impairment (in contrast to relying on reported diagnoses as proxy measures of such) have been fewer and demonstrate inconsistent findings. Thus, we were interested in using data from this nationally representative sample of U.S. children to examine whether atopic dermatitis was associated with symptoms of learning or memory difficulties. Moreover, we wanted to examine how this relationship is influenced by known neurodevelopmental conditions to further characterize whether specific subgroups of children with atopic dermatitis are more susceptible to cognitive impairments.

Author Interviews, Cancer Research, Microbiome / 07.03.2024

MedicalResearch.com Interview with: Dr Ashray Gunjur MBBS (Hons), B. Med Sci, MPHTM FRACP Clinical Research Training Fellow Melbourne, Australia   MedicalResearch.com: What is the background for this study? Response: As background, the last ~5 years have seen a surge of interest in the relationship between gut microbiota and cancer response to immune checkpoint blockade (ICB). We know that though a fraction of many different cancer types will respond to these therapies, it is currently very hard to predict who that will be- so ‘microbiome’ based biomarkers to select patients, or even strategies to change a patient’s microbiome to enhance their chance of responding, are very attractive. A key challenge, however, has been a lack of consistency in the microbes associated with response or non-response across different studies from different regions. While geographic, methodological, and technical variation likely contribute to this, most studies examined the gut microbiome at a genus- or species- taxonomic rank level, while we know there is significant intra-species (strain-level) diversity. As such, one of our key research questions was whether we could improve the reproducibility of microbial ‘signatures’ of response across cohorts using higher resolution approaches- with our hypothesis being that strain-resolution signatures would outperform species- or lower resolution signatures. We obtained our signature by analysing baseline faecal samples from the CA209-538 clinical trial, a wonderful investigator-initiated study sponsored by the Olivia Newton-John Cancer Research Institute (Melbourne, Australia). I was fortunate enough to work on this trial as a clinical investigator while training to be a medical oncologist. (more…)

MedicalResearch.com Interview with: Rosangela Akemi Hoshi, Ph.D. Lemann Foundation Cardiovascular Research Postdoctoral Fellowship Center for Lipid Metabolomics Divisions of Preventive and Cardiovascular Medicine Brigham and Women's Hospital Boston, MA  MedicalResearch.com: What is the background for this study? Would you describe the IgG N-glycan profile? Response: Glycans are sugar coatings of proteins, made of monosaccharide building blocks, that are involved in a variety of biological pathways.  Different sugar structures can dictate or modify the protein’s activity through specific interactions with cellular receptors. For example, proteins lacking glycans have a reduced level or a complete loss of function. Glycans are of such importance that the 2022 Nobel Prize in chemistry was awarded for glycan-based science. In this study, we examined glycans attached to Immunoglobulins G (IgG) and their link with incidence of cardiovascular disease (CVD) due to their impact on IgG inflammatory properties. Since inflammation is not only a cause, but also an aggravating factor and a mediator of a worse prognosis in cardiometabolic disorders and CVD, we investigated whether different glycan structures may characterize an at-risk phenotype for CVD development. Determining glycan profiles involved in multiple conditions can serve prognostic and diagnostic purposes. Yet, unlike other types of macromolecules, glycans are still not as much explored, characterizing a promising but underappreciated class that should be further investigated. (more…)
Author Interviews, Nature, Technology, University of Pittsburgh / 26.02.2024

MedicalResearch.com Interview with: Jishnu Das, Ph.D. Center for Systems Immunology Departments of Immunology and Computational & Systems Biology, Assistant Professor School of Medicine University of Pittsburgh MedicalResearch.com:  What is the background for this study? How does this new AI model work?  How is it different from other models? Response: Modern multi-omic technologies generate an enormous amount of data across scales of organization, and with differing resolution. While recent machine learning methods have harnessed these to predict clinical/physiological outcomes, they are often black boxes that do not provide meaningful inference beyond prediction. Differences in data generation modalities, redundancy in the data, as well as large numbers of irrelevant features make inference of biological mechanisms from high-dimensional omic datasets challenging. To address these challenges, we developed a machine learning technique called SLIDE (Significant Latent Factor Interaction Discovery and Exploration). We reasoned that features that are directly measured by current technologies are constrained by strengths and weaknesses of current platforms. So, while some observed features may be excellent correlates of outcomes of interest, inferring biological mechanisms from these multi-omic datasets requires us to delve beyond the observable into the hidden states, i.e., latent factors. These hidden states encapsulate the true drivers of underlying biological processes and capture a complex multi-scale interplay between entities measured by these datasets. Our method moves beyond simple biomarkers/correlates (“the what”) to hidden states that actually explain clinical/physiological outcomes (“the how” and “the why”). (more…)

MedicalResearch.com Interview with: Frank Wang MD William B. Taylor Endowed Professor of Clinical Dermatology Associate Professor, Dermatology Associate Chair for Education Assistant Program Director, Dermatology Residency Program University of Michigan Ann Arbor, Michigan MedicalResearch.com: What is the background for this study? How is the cross-linked hyaluronic acid obtained? Where was it injected? Response: As the skin undergoes photoaging due to chronic exposure to ultraviolet light, it loses dermal collagen, which in turn leads to wrinkling, lines, and loss of support. The loss of collagen is, in large part, due to reduced function of the skin’s collagen-producing cells, dermal fibroblasts. We wanted to investigate whether it was possible to reverse the decreased function of fibroblasts in photodamaged skin, by introducing a space-filling material into the dermis, injected CL-HA dermal filler. The CL-HA filler we used was donated to us for research purposes. We performed injections of CL-HA into the mid-dermis (as is normally done when injected into the face) of severely photoaged forearm skin of human participants over the age of 60. We then examined skin samples at various time points, including 1, 2, 3 and 4 weeks and 3, 6, 9, and 12 months post-injection. (more…)
Author Interviews, Diabetes, Orthopedics, Weight Research / 14.02.2024

MedicalResearch.com Interview with: Matthew Magruder, MD PGY3 Orthopaedic Residency Program Department of Orthopaedic Surgery and Rehabilitation Maimonides Medical Center MedicalResearch.com: What is the background for this study? Response: The prevalence of obesity and diabetes mellitus has reached epidemic proportions. Approximately 37.3 million people in the United States, accounting for 11.3% of the total population, have diabetes, and 100.1 million, or 41.9%, of all US citizens are obese. Furthermore, these numbers are only projected to increase in the coming decades. This is an issue for orthopaedic surgeons because diabetes and obesity have consistently been demonstrated to be risk factors for complications following total joint replacements, especially total hip replacements. Therefore, we are in desperate need of new and more effective tools in mitigating the risk of poor outcomes in our joint replacement patients. Semaglutide, and other GLP-1 agonists, are potentially a new tool that can be used to help decrease the risks following joint replacement surgery. Initially a medication to treat diabetes, semaglutide has recently been approved by the FDA to treat obesity as well, as randomized controlled trials have consistently demonstrated significant weight loss with minimal side effects. The purpose of our study was to see what effect the use of semaglutide had on total hip arthroplasty patient outcomes. (more…)
