- 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…)
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, 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.

Author Interviews, CDC, NEJM, Pulmonary Disease / 23.04.2020
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…)
Author Interviews, CDC, OBGYNE, Pediatrics, Sexual Health, STD / 21.05.2019
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: Kathryn 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…)
