Author Interviews, CDC, Infections / 20.05.2024

MedicalResearch.com Interview with: Cathryn Haigh, Ph.D. Chief Prion Cell Biology Unit Laboratory of Neurological Infections and Immunity National Institute of Allergy and Infectious Diseases Division of Intramural Research, Rocky Mountain Laboratories National Institutes of Health Hamilton, MT 59840 MedicalResearch.com: What is the background for this study,  ie what are prions/prion-related diseases?  Where are prions found? Response: Prion diseases are infectious neurodegenerative diseases of humans and animals.  In humans these diseases often manifest as rapidly progressing dementias but are rarely caused by a known exposure to the infectious agents (prions).  More commonly they are sporadic (no known cause) or hereditary. One form of human disease is believed to have arisen from eating beef contaminated with bovine spongiform encephalopathy (as known as mad cow disease).  This has resulted in concerns that chronic wasting disease (CWD), a prion disease affecting deer, elk and moose, might also have the potential to cross the species barrier and cause disease in humans.  To date, transmissions of CWD prions to cynomolgus macaques have been negative, a good sign that crossing the species barrier would not be easy, but macaques are not human so we wanted to test whether CWD could infect human brain tissue. To do this we used a human cerebral organoid model (mini human brain tissues grown from skin cells in a laboratory) and directly exposed the organoids to prions from the brains of animals that had died of CWD.

MedicalResearch.com Interview with: Dr. Tessa Clemens, PhDH Health scientist in the Division of Injury Prevention CDC’s National Center for Injury Prevention and Control   MedicalResearch.com: What is the background for this study? Response: Data showed an increase in drowning deaths after years of decline and drowning is the leading cause of death among children ages 1-4. We know that swimming lessons reduce the risk of drowning, but not everyone has the same access to swimming lessons. In this study, we described which groups saw the greatest increases in drowning and analyzed swimming skills and swimming lesson participation data. (more…)
Author Interviews, CDC, Infections, JAMA / 27.04.2024

MedicalResearch.com Interview with: Shruti K. Gohil, MD Assistant Professor, Infectious Diseases, Department of Medicine Associate Medical Director, Epidemiology & Infection Prevention, Infectious Diseases UCI School of Medicine MedicalResearch.com: What is the background for this study?
  • 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.

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.

Allergies, Author Interviews, CDC, Environmental Risks / 04.08.2023

MedicalResearch.com Interview with: Ann Carpenter DVM, MPH Epidemic Intelligence Service Officer Centers for Disease Control and Prevention Primary author of the recent CDC MMWR report.  MedicalResearch.com: What is the background for this study? Would you briefly describe Alpha-gal Syndrome?  Response: Alpha-gal syndrome is an emerging and potentially life-threatening allergic condition that is associated with a tick bite. It is also called alpha-gal allergy, red meat allergy, or tick bite meat allergy. Increasing case studies and anecdotal reports suggested that AGS was a growing concern, but, prior to these studies, information on clinician awareness and the number of people impacted was not available at a national level.

Annals Internal Medicine, Author Interviews, CDC, Infections / 29.03.2023

MedicalResearch.com Interview with: Dr. Meghan Lyman MD Medical Officer in the Mycotic Diseases Branch CDC MedicalResearch.com: What is the background for this study? Response: Candida auris (C. auris) is a fungus considered an urgent public health threat because it is often multi-drug resistant and spreads easily in healthcare settings.  CDC has been conducting tracking cases and is concerned about increasing numbers and geographic spread of C. auris cases in recent years, suggesting increased transmission.  Because C. auris cases and resistance are rising in the U.S., immediate public health actions to stop this threat are critical.

Addiction, Author Interviews, CDC, PLoS, Race/Ethnic Diversity, UCLA / 23.03.2023

MedicalResearch.com Interview with: Maria-Rita D'Orsogna Ph.D. Professor, Mathematics California State University, Northridge Adjunct Associate Professor Department of Computational Medicine at UCLA MedicalResearch.com: What is the background for this study? Response: Drug overdose deaths have been increasing in the USA for the past two decades. A ‘third wave’ of overdose fatalities started in 2013, with a shift from prescription opioids towards synthetic ones, in particular illicit fentanyl. To examine trends in drug overdose deaths by gender, race and geography in the United States during the period 2013-2020, we used an epidemiological database provided by the Centers for Disease Control and Prevention, extracting rates by race and gender in all 50 states plus the District of Columbia. We considered the impact of four main drug categories psychostimulants with addiction potential such as methamphetamines; heroin; prescription opioids and synthetic opioids such as fentanyl and its derivatives.

Author Interviews, CDC, Cost of Health Care, Hepatitis - Liver Disease / 05.10.2022

MedicalResearch.com Interview with: William W. Thompson, Ph.D. Epidemiologist Division of Viral Hepatitis CDC MedicalResearch.com: What is the background for this study? Response: Prior to this analysis, we knew only an estimated 1.2 million persons initiated hepatitis C treatment with DAA agents in the United States during 2014–2020, far below the number needed to achieve national hepatitis C elimination goals. Further, the number of persons treated was highest in 2015 and declined to its lowest level in 2020. This analysis used a large national health care claims database to assess the level and timing of hepatitis C treatment among persons with diagnosed HCV infection with breakdowns by sex, age, race, insurance type (i.e., private, Medicaid, and Medicare), and by state.

Author Interviews, CDC, COVID -19 Coronavirus, Emory, Heart Disease, JAMA / 25.01.2022

MedicalResearch.com Interview with: Matthew Oster, MD, MPH CDC COVID-19 Response CDC Center on Birth Defects and Developmental Disabilities Pediatric Cardiologist, Sibley Heart Center, Children’s Healthcare of Atlanta Emory University School of Medicine Emory University Rollins School of Public Health MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: More than 192 million people ages 12 years and older in the U.S. received at least one dose of mRNA COVID-19 vaccines from December 2020 through August 2021. From this population, VAERS (the Vaccine Adverse Event Reporting System) received 1,991 reports of myocarditis,  1,626 of which met the case definition of myocarditis. Rates of myocarditis were highest following the second dose of an mRNA vaccine among males aged 12–15 years (70.7 per million doses of Pfizer), 16-17 years (105.9 per million doses of Pfizer), and 18–47 years (52.4 and 56.3 per million doses of Pfizer and Moderna, respectively). Of those with myocarditis, the median age was 21 years and the median time from vaccination to symptom onset was two days. Males accounted for 82% of patients for whom sex was known. Approximately 96% were hospitalized, 87% of whose symptoms had gone away by the time they were discharged from the hospital. Non-steroidal anti-inflammatory drugs (589/676, 87%) were the most common treatment. (more…)
Author Interviews, CDC, Opiods / 28.12.2021

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.

Author Interviews, CDC, Infections / 07.12.2021

MedicalResearch.com Interview with: Michael Craig MPP Director, Antibiotic Resistance Coordination and Strategy CDC  MedicalResearch.com: What is the mission of the Global Action in Healthcare Network (GAIHN)? How will it work to coordinate detection and response efforts across multiple countries and cultures? 
  • Health care can often be an epicenter of infectious disease outbreaks that can spread within a facility, between facilities, and beyond the facility into the community. CDC’s Global Action in Healthcare Network (GAIHN) consists of countries, healthcare facilities, and public health partners working together to prevent, detect, and respond to infectious disease threats in the healthcare setting. GAIHN will target health care threats like antimicrobial-resistant infections, healthcare-associated infections (HAIs), and COVID-19 through infection prevention and control.
  • Close coordination across experts at CDC, and strong relationships and communications with our funded partners, international colleagues, ministries of health and country leadership, will make GAIHN successful and ensure collaboration, minimize duplication, and maximize advancements across countries and cultures.

Author Interviews, CDC, Emergency Care, JAMA / 06.10.2021

MedicalResearch.com Interview with: Dr. Daniel S.  Budnitz MD MPH CAPT, USPHS Division of Healthcare Quality Promotion Director, Centers for Disease Control and Prevention’s Medication Safety Program Atlanta, Georgia  MedicalResearch.com: What is the background for this study?  Response: Medications are generally safe when used as prescribed or as directed on the label, but there can be risks in taking any medication. Adverse drug events are harms resulting from the use of medication. The risk of adverse drug events is highest among older adults and very young children. Older adults have higher risks because they typically take more medications and are more likely to have underlying medical conditions. Very young children have higher risks because they often find and ingest medications meant for others. Previous studies of medication safety have focused on harm from medications when taken for therapeutic reasons. Separate studies have focused on harm from specific types of non-therapeutic use (taking medications for recreational use or self-harm). This study examined the number of emergency department (ED) visits that resulted when people who took medications for any reason – as directed by a clinician or for other reasons, including recreational use or intentional self-harm.  (more…)

MedicalResearch.com Interview with: Anne Hause PhD Epidemiologist Centers for Disease Control and Prevention  MedicalResearch.com: What is the background for this study? Response: On August 12, 2021, the Food and Drug Administration (FDA) amended Emergency Use Authorizations (EUA) for the Pfizer-BioNTech and Moderna COVID-19 vaccines to authorize administration of an additional dose following completion of a primary vaccination series to eligible persons with moderate to severe immunocompromise.  (more…)
Author Interviews, CDC, JAMA, Sexual Health, STD, USPSTF / 21.09.2021

MedicalResearch.com Interview with: Martha Kubik, Ph.D., R.N. Professor, School of Nursing College of Health and Human Services George Mason University Member, U.S. Preventive Services Task Force MedicalResearch.com: What is the background for this study? Are these infections increasing in incidence in the US? Response: Chlamydia and gonorrhea are two of the most common sexually transmitted infections in the U.S. More people are being diagnosed with both of these STIs than ever, with nearly 2 million cases of chlamydia and more than 600,000 cases of gonorrhea reported in 2019, according to the CDC. Because most do not have symptoms, screening is vitally important to help ensure that these infections are discovered and treated, and serious health complications prevented. (more…)

MedicalResearch.com Interview with: Scott Pauley Press Officer, News Media Branch Division of Public Affairs Office of the Associate Director for Communication MedicalResearch.com: What is the background for this study?
  • In this real-world study of vaccine effectiveness:
    • Researchers compared hospitalized patients who tested positive for the virus that causes COVID-19 (case patients) to hospitalized patients who tested negative for the virus (control patients)
    • Vaccine effectiveness was calculated for each type of vaccine by comparing the proportion of cases patients and control patients vaccinated
    • 3,689 patients were included (1,682 case-patients and 2,007 control-patients)
Vaccination status breakdown: 2,362 unvaccinated; 476 fully vaccinated with Moderna; 738 fully vaccinated with Pfizer-BioNTech; and 113 fully vaccinated with Janssen vaccine. (more…)
Author Interviews, CDC, HPV, JAMA, Vaccine Studies / 17.09.2021

MedicalResearch.com Interview with: Kalyani Sonawane, PhD Assistant Professor of Management, Policy and Community Health UTHealth School of Public Health in Houston MedicalResearch.com: What is the background for this study? Response: Safety concern regarding the HPV vaccine is one of the most significant barriers to vaccination. Our objective was to determine how many US adolescents did not initiate the HPV vaccine during 2015-2018 because their parents had concerns regarding the vaccine’s safety. We also analyzed vaccine adverse event reporting data, in parallel, to understand if the public sentiment of HPV vaccine safety is in alignment with evidence from the vaccine safety surveillance system.  (more…)

Author Interviews, CDC, COVID -19 Coronavirus, Heart Disease, JAMA, UCSD / 01.07.2021

MedicalResearch.com Interview with: Margaret Ryan MD MPH Medical Director of Defense Health Agency Immunization Healthcare Division Pacific Region Office, San Diego CA Clinical Professor at the University of California San Diego MedicalResearch.com: What is the background for this study? What are the main findings? Response: Military clinicians, especially those in the Defense Health Agency Immunization Healthcare Division, first became aware of a few cases of myocarditis following COVID-19 vaccination in early Feb 2021.  These cases included young men who presented with chest pain a few days after 2nd dose of mRNA (Pfizer or Moderna) vaccine.  As more young people became eligible for 2nd doses of vaccine, more cases were identified.  By late April, the military had identified 23 cases of myocarditis, with remarkably similar presentations, after COVID-19 vaccination.  This case series is described in the current issue of JAMA Cardiology.

Author Interviews, CDC, Diabetes, Social Issues / 30.06.2021

MedicalResearch.com Interview with: Yu Chen, Ph.D. Prevention Effectiveness Fellow Division of Diabetes Translation CDC MedicalResearch.com: What is the background for this study? Response: Overall prevalence of diabetes has increased over the past two decades in the US, disproportionately affecting populations with low-income. The age-adjusted prevalence of diagnosed diabetes among adults aged 18 years or older increased from 6.4% in 1999−2002 to 9.4% in 2013−2016. Between 2011 and 2014, compared with persons with high income, the relative percentage increase in diabetes prevalence was 40.0%, 74.1%, and 100.4% for those classified as middle income, near poor and poor, respectively. However, recent changes in income-related inequalities in diabetes prevalence are unknown. (more…)
Author Interviews, CDC, COVID -19 Coronavirus, JAMA, Pediatrics / 11.06.2021

MedicalResearch.com Interview with: Angela P. Campbell, MD, MPH Medical Officer Epidemiology and Prevention Branch in the Influenza Division MIS-C Incidence Authorship Group CDC MedicalResearch.com: What is the background for this study?
  • Response: Multisystem inflammatory syndrome in children (MIS-C) is a serious condition associated with COVID-19 where different body parts can become inflamed, including the heart, lungs, kidneys, brain, skin, eyes, and gastrointestinal organs. Children with MIS-C may have a fever and various symptoms, including abdominal (gut) pain, vomiting, diarrhea, neck pain, rash, bloodshot eyes, or feeling extra tired. Not all children with MIS-C have the same symptoms.
  • It is still not known exactly how MIS-C may be linked to prior COVID-19 infection. However, 99% of cases in the CDC national surveillance system tested positive for COVID-19. The remaining 1% were around someone with COVID-19.
  • MIS-C incidence might vary by certain patient characteristics, such as such as race, ethnicity, age, sex and geographic location.
  • In this study we estimated the rate of MIS-C cases overall in the general population as well as the rate of MIS-C cases among those with COVID-19.

Author Interviews, CDC, Clots - Coagulation, COVID -19 Coronavirus, JAMA / 05.05.2021

MedicalResearch.com Interview with: Isaac See, MD Centers for Disease Control and Prevention COVID-19 Response Team Atlanta, Georgia MedicalResearch.com: What is the background for this study? Response: On February 27, 2021 the U.S. Food and Drug Administration (FDA) granted emergency use authorization for the Janssen/Johnson & Johnson (J&J) COVID-19 Vaccine in people 18 years of age or older in the United States.  The Janssen/J&J COVID-19 Vaccine uses a replication-deficient (i.e., cannot cause infections) human adenovirus vector.  In mid-March, the European Medicines Agency announced that they had conducted a preliminary investigation of cases of blood clots and low counts of blood cells called platelets in patients who had recently received the Oxford/AstraZeneca COVID-19 Vaccine, which uses a replication-deficient chimpanzee adenovirus vector.  This syndrome of blood clots and low platelet counts has been called thrombosis with thrombocytopenia syndrome, or TTS.  The European investigation showed that over 70% of their cases specifically involved blood clots in particular veins inside the brain, a condition caused cerebral venous sinus thrombosis (CVST), in addition to low platelet counts (thrombocytopenia is the medical term for low platelet counts). CVST is already a rare condition, and CVST with thrombocytopenia is even rarer.  By April 12, 2021, approximately 7 million doses of the Janssen/J&J COVID-19 Vaccine had been given in the United States, and six cases of CVST and thrombocytopenia after receipt of the Janssen/J&J COVID-19 Vaccine had been reported to the U.S. Vaccine Adverse Event Reporting System (VAERS), which is the U.S. national vaccine safety monitoring system.  The next day (April 13, 2021) CDC and FDA recommended a pause in use of the vaccine recommended to allow for further investigation of these events.  On April 23, 2021 data about the first 12 cases reported after authorization of the Janssen/J&J COVID-19 Vaccine were presented at an emergency meeting of the Advisory Committee on Immunization Practices (ACIP) to decide what to recommend regarding the Janssen COVID-19 vaccine.  The ACIP concluded that the benefits of resuming Janssen COVID-19 vaccination among persons aged 18 years or older outweighed the risks and reaffirmed its interim recommendation under the FDA’s Emergency Use Authorization.  The FDA’s Emergency Use Authorization includes a new warning for rare clotting events among women aged 18 to 49 years. Our report provides clinical details about these first reported 12 U.S. cases of CVST and thrombocytopenia following receipt of the Janssen COVID-19 Vaccine. (more…)
Author Interviews, CDC, COVID -19 Coronavirus / 06.04.2021

MedicalResearch.com Interview with: Michael S. Pollard Ph.D Senior Sociologist; Professor Pardee RAND Graduate School MedicalResearch.com: What is the background for this study? Response: The Centers for Disease Control and Prevention (CDC) has traditionally been a highly trusted source of public health information, and conveying information to the public about the vaccine and broader pandemic response is critical.  This study examines changes in levels of public trust in the CDC between May and October, 2020, in light of the numerous challenges the CDC initially faced during the COVID-19 pandemic: technical problems with their COVID-19 testing kits, mixed messaging about the pandemic and mitigation strategies, and public commentary and interference by people in the Trump administration, for example.

Author Interviews, CDC, COVID -19 Coronavirus, Emory, JAMA, Occupational Health / 12.03.2021

MedicalResearch.com Interview with: Jesse T. Jacob, MD School of Medicine Director, Antibiotic Stewardship Program Emory University, Atlanta, Georgia MedicalResearch.com: What is the background for this study? Response: Since coronavirus disease 2019 (COVID-19) was recognized in the United States in January 2020, the risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) attributed to exposures in the health care workplace has been studied with conflicting results, and the role of job functions (such as nurse) or specific workplace activities, including care for individuals with known and unknown SARS-CoV-2 positivity, increase the risk of SARS-CoV-2 infection. We assessed more than 24,000 healthcare providers between April and August 2020 across four large academic medical systems (Emory, Johns Hopkins, Rush University Medical Center, and University of Maryland) which collaborate in the CDC’s Prevention Epicenter Program and conduct innovative infection prevention research. Each site conducted voluntary COVID-19 antibody testing on its health care workers, as well as offered a questionnaire/survey on the employees’ occupational activities and possible exposures to individuals with COVID-19 infection both inside and outside the workplace. We also looked at three-digit residential zip-code prefixes to determine COVID-19 prevalence in communities.   (more…)
Author Interviews, CDC, JAMA, Stroke, USPSTF / 11.02.2021

MedicalResearch.com Interview with: Aaron B. Caughey, M.D., M.P.P., M.P.H., Ph.D. Professor and Chair Department of Obstetrics and Gynecolog Associate dean for Women’s Health Research and Policy Oregon Health & Science University    Portland, OR. Founder and Chair Centers for Disease Control and Prevention–funded Oregon Perinatal Collaborative MedicalResearch.com: What is the background for this study? What are the main findings? Response: Stroke is a leading cause of death and disability in the United States and can be devastating to those affected. One of many risk factors for stroke is carotid artery stenosis (CAS), which is the narrowing of the arteries that run along the sides of the neck and supply blood to the brain. The Task Force wants to help prevent people from having a stroke, but evidence shows that screening for CAS in people without symptoms does not help prevent strokes and can actually lead to harmful events such as stroke, heart attack, or death. Since the harms of screening greatly outweigh the benefits, the Task Force continues to recommend against screening for CAS among adults who do not have any signs or symptoms of a blocked artery in the neck.

MedicalResearch.com Interview with: Jiajia Chen, PhD Division of Reproductive Health National Center for Chronic Disease Prevention and Health Promotion Centers for Disease Control and Prevention, Atlanta, Georgia MedicalResearch.com: What is the background for this study? Response: Severe maternal morbidity (SMM) includes a range of serious pregnancy complications that result in significant short-term or long-term consequences to a woman’s health. Most research and prevention efforts addressing SMM focus on the delivery hospitalization, but less is known about SMM diagnosed after delivery discharge. (more…)
Author Interviews, CDC, COVID -19 Coronavirus, JAMA / 08.01.2021

MedicalResearch.com Interview with: Jay C. Butler, MD, FAAP, MACP, FIDSA Deputy Director for Infectious Diseases Centers for Disease Control and Prevention Atlanta, GA  30333 MedicalResearch.com: What is the background for this study? Response: There are still disagreements about the significance of transmission of SARS-CoV-2 from asymptomatic persons.  It has been known since at least March 2020 that, unlike the closely related coronavirus that causes SARS, transmission of COVID-19 from asymptomatic and presymptomatic persons occurs and that at least 30% of infected persons do not develop symptoms.  Estimating the proportion of transmissions from persons without symptoms informs the decision analysis for prioritization of community mitigations opportunities:  wearing of masks, social distancing, and hand hygiene. If only a low proportion of transmission occurs from people without symptoms, these interventions would be less likely to control transmission when broadly applied in the community.  On the other hand, if a significant proportion of spread is from infected persons without symptoms, the value of these measures is enhanced. Additionally, obtaining strategic and systematic screening tests for SARS-CoV-2 to identify and isolate persons without symptoms in selected settings, such as congregational housing settings, will have greater potential impact if spread from persons without symptoms is common.  (more…)
