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: 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.

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, Emory, Infections, JAMA, MRSA / 10.10.2023

MedicalResearch.com Interview with: Dr. John Jernigan, MD MS Clinical Associate Professor of Medicine Division of Infectious Diseases Emory University School of Medicine Branch Chief Epidemiology, Research and Innovations Branch CDC Center for Disease Control MedicalResearch.com: What is the background for this study? Response: Staphylococcus aureus commonly causes infections in ICUs. One approach to preventing these infections is using nasal mupirocin plus chlorhexidine gluconate (CHG) bathing for ICU patients. This practice is known to prevent methicillin-resistant Staphylococcus aureus (MRSA) infections and all-cause. bloodstream infections.  This practice has been broadly adopted in ICUs in the US, but adoption of mupirocin as a universal topical antibiotic has been slowed by concerns for engendering mupirocin resistance. This cluster-randomized trial in adult ICUs was conducted to assess whether universal nasal antiseptic povidone-iodine (iodophor), to which minimal S. aureus resistance is expected, was an acceptable alternative to universal nasal mupirocin for reducing S. aureus and MRSA clinical cultures in the setting of daily CHG bathing. Those who received chlorhexidine (CHG) bathing with mupirocin had an 18% reduction in risk of Staphylococcus aureus clinical cultures and a 15% reduction in risk of methicillin-resistant S. aureus (MRSA) clinical cultures compared to patients who received CHG bathing with intranasal iodophor.  These results show that using mupirocin for nasal decolonization may be preferred over iodophor because it is more effective at preventing S. aureus infections.

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.

MedicalResearch.com Interview with: Fernanda Lessa, MD, MPH Chief, CDC’s International Infection Control Program Co-author of the paper MedicalResearch.com: What is the background for this study? What are the main findings? Response: Data from low- and middle-income countries on the impact of the COVID-19 pandemic on antibiotic use among outpatients are sparse. This study evaluated the changes in prescribing rates of antibiotics commonly prescribed for respiratory tract infections by outpatient providers among adults in Brazil. We observed increases during the pandemic in outpatient prescriptions of azithromycin and ceftriaxone of up 360% and 90%, respectively, based on age and sex. (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.

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, 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…)

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.

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…)

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, Diabetes, Gender Differences, Race/Ethnic Diversity / 29.06.2020

MedicalResearch.com Interview with: Giuseppina Imperatore, MD, PHD CDC, Atlanta MedicalResearch.com: What is the background for this study? Response: The lifetime risk of diabetes (LRD), a probability of developing diabetes during a person’s lifespan, is a measure of future disease burden that reflects the impact of incidence (occurrence of new cases per year) and mortality. The years of potential life lost to diabetes (YPLLD) is the number of life-years lost due to diabetes, calculated as the difference between the life expectancy of a person without diabetes and a person with diabetes at the age of diagnosis. For example, the number of life-years lost for a person diagnosed at age 20 years is the difference in life expectancy of a person who died without developing diabetes and a person who was diagnosed with diabetes at 20 years of age.  Both incidence and mortality of diabetes have been decreasing for more than a decade. The effects of those changes on lifetime risk of diabetes and years of potential life lost to diabetes are not known. In this study, we used nationally representative diabetes surveillance data to provide updated estimates for the lifetime probability of development of diabetes, and to assess changes in incidence and mortality on lifetime risk and life-years lost due to diabetes in the USA.

MedicalResearch.com Interview with: Angela K. Werner, PhD, MPH Environmental Public Health Tracking Program National Center for Environmental Health CDC MedicalResearch.com: What is the background for this study? Response: In August 2019, emergency department (ED) visits related to e-cigarette, or vaping, product-associated lung injury (EVALI) increased sharply, followed by a peak in September. This was followed by a gradual but persistent decline in the number of cases. As of February 18, 2020 (CDC’s latest and final published update), there were a total of 2,807 hospitalized EVALI cases or deaths reported to CDC from all 50 states, the District of Columbia, and two U.S. territories (Puerto Rico and U.S. Virgin Islands). Sixty-eight deaths were confirmed in 29 states and the District of Columbia. Although clinical presentations and outcomes of EVALI patients have been reported, data on patients who died are more limited. This article fills a gap by reporting on a national study assessing detailed demographic, substance use, and clinical characteristics of EVALI patients who have died, and comparing them to the characteristics of EVALI patients who survived.

MedicalResearch.com Interview with: Nuadum Konne Waterborne Disease Prevention Branch CDC  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: An estimated 45 million Americans enjoy the benefits of contact lens wear. Most of them practice some behaviors that put them at risk for serious eye infections. Surveys of contact lens wearers and eye care providers were conducted in 2018. One third of lens wearers recalled never hearing any lens care recommendations. Most eye care providers reported sharing recommendations always or most of the time. (more…)

MedicalResearch.com Interview with: Lara B. McKenzie, PhD, MA Principal Investigator in the Center for Injury Research and Policy Research Institute at Nationwide Children's Hospital Associate Professor in the Department of Pediatrics College of Medicine and the Division of Epidemiology College of Public Health at The Ohio State University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Social media and other online tools have changed the way people seek and share health information. Recent consumer interest in natural, organic, and ethically-made personal care products has led to an increase of shared recipes for homemade products including sunscreen. The study found that nearly all (95%) pins, or bookmarks, for homemade sunscreen positively portrayed the effectiveness of homemade sunscreens and most (68%) recommended recipes for homemade sunscreens that offered insufficient UV radiation protection. Sun Protection Factor (SPF) claims were made in a third of pins with a range of SPF 2 to SPF 50. This is concerning because the ingredients recommended in homemade sunscreen pins offer minimal scientifically proven broad-spectrum protection from UV radiation yet are widely shared and promoted as safe alternatives to commercial sunscreens on Pinterest. Homemade sunscreen products are risky because they are not regulated or tested for efficacy like commercial sunscreens. When you make it yourself, you don’t know if it’s safe or effective. With rising skin cancer rates, the use of effective broadband sunscreen is critical to protect the skin from UV radiation and reduce incidence of skin cancer.  (more…)

MedicalResearch.com Interview with: Lee Warner, PhD Chief of the Women’s Health and Fertility Branch Division of Reproductive Health CDC MedicalResearch.com: What is the background for this study? Response: Previous research has found lower prevalence of condom use combined with the most effective reversible contraceptive methods among teens, but this is the first study to our knowledge to confirm the finding among sexually active teen mothers in the postpartum period. Our new paper finds that only 3 in 10 postpartum teen mothers report using condoms combined with a more effective contraceptive method (either long-acting reversible contraception or LARC or a non-LARC hormonal method). Dual use was 50 percent lower among LARC users compared with users of non-LARC hormonal methods. (more…)

Author Interviews, CDC, Pediatrics, Vaccine Studies, Vanderbilt / 18.10.2018

MedicalResearch.com Interview with: "Vacuna influenza / Flu vaccine" by El Alvi is licensed under CC BY 2.0Kathryn M. Edwards, M.D. Sarah H. Sell and Cornelius Vanderbilt Chair in Pediatrics Professor of Pediatrics Vanderbilt University School of Medicine Dr. Edwards discusses the statement from the Infectious Diseases Society of America (IDSA) regarding the Centers for Disease Control and Prevention’s new data on child vaccine rates across the United States. MedicalResearch.com: What is the background for this study? What are the main findings? Response: To monitor the uptake of vaccines the CDC conducts a National Immunization Survey each year.  This survey is conducted by random-digit dialing (cell phones or landlines) of parents and guardians of children 19-35 months of age.  The interviewers ask the families who provides the vaccines for their children and if these providers can be contacted to inquire about the immunizations received.  The overall response rate to the telephone survey was 26% and immunization records were provided on 54% of the children where permission was granted.  Overall 15, 333 children had their immunization records reviewed. When comparing immunization rates for 2017 and 2016, the last two years of the study, several new findings were discovered. First the overall coverage rate for 3 doses of polio vaccine, one dose of MMR, 3 doses of Hepatitis b, and 1 dose of chickenpox vaccine was 90%, a high rate of coverage.  Children were less likely to be up to date on the hepatitis A vaccine (70%) and rotavirus vaccine (73%). Coverage was lower for children living in rural areas when compared with urban areas and children living in rural areas had higher percentages of no vaccine receipt at all (1.9%) compared with those living in urban areas (1%). There were more uninsured children in 2017 at 2.8% and these children had lower immunization rates.  In fact 7.1% of the children with no insurance were totally unimmunized when compared with 0.8% unimmunized in those with private insurance. Vaccine coverage varies by state and by vaccine. (more…)
