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…)
Author Interviews, CDC, Hepatitis - Liver Disease, JAMA, USPSTF / 21.12.2020

MedicalResearch.com Interview with: Aaron B. Caughey, M.D.,M.P.P., M.P.H. Professor and Chair of the Department of Obstetrics and Gynecology 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 USPSTF Task Force Member  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Hepatitis B virus infection is a serious condition that affects about 860,000 people in the United States. Screening for hepatitis B can detect the infection early, so that you can receive treatment that will reduce the potential for serious complications, including cancer, liver failure, and even death. Hepatitis B often has no signs or symptoms, so clinicians should screen teens and adults who are at increased risk for hepatitis B to help protect their health. (more…)
Author Interviews, Cancer Research, CDC, JAMA, Lung Cancer / 10.12.2020

MedicalResearch.com Interview with: David A. Siegel, MD, MPH Division of Cancer Prevention and Control US Centers for Disease Control and Prevention Atlanta, Georgia MedicalResearch.com: Why is it important to better understand the smoking histories (both current/former and never smokers) among lung cancer patients? Response: Knowledge of smoking status of patients diagnosed with lung cancer can help us understand how to best prevent, detect, and treat lung cancer in the future. More than 84% of women and 90% of men newly diagnosed with lung cancer had ever smoked cigarettes, and half of patients aged 20 to 64 years newly diagnosed with lung cancer were current cigarette smokers. These findings reinforce the importance of cigarette cessation and lung cancer screening. 1 out of every 8 people diagnosed with lung cancer had never smoked cigarettes, which reiterates the importance of learning more about their risk factors for lung cancer, which could impact prevention and treatment.  (more…)
Author Interviews, Cannabis, Pediatrics / 02.10.2020

MedicalResearch.com Interview with: Heather Breeze Clayton, PhD, MPH Senior Scientist, National Center for Injury Prevention and Control CDC MedicalResearch.com: What is the background for this study? Response: Thirty-three states and the District of Columbia now have policies in place legalizing marijuana for medical or adult use. While the health effects of marijuana use continue to be studied, substantial evidence suggests that a number of health risks – including cognitive and mental health outcomes- are made worse by earlier initiation of marijuana, and heavier use patterns. Scientific knowledge about the association between marijuana use and other health and risk-taking behavior in youth is still evolving. Accordingly, we sought to use nationally representative data from the Youth Risk Behavior Survey to assess what the relationship is between different patterns of marijuana use in youth (more established use vs. non-established use patterns) and a number of risk-taking and violence related behaviors.

MedicalResearch.com Interview with: Dr. Nathan Furukawa, MD, MPH Medical officer, Division of HIV/AIDS Prevention CDC MedicalResearch.com: What is the background for this study? Response: The cost of the PrEP medication is the largest driver of the cost of providing PrEP care. Most patients need insurance or help from a medication assistance program to cover the large costs of the PrEP medication. We wanted to describe how these costs were paid by patients (out-of-pocket payments) and insurers (third-party payments) nationally.    MedicalResearch.com: What are the main findings? Response: The study found that the cost for a month of the PrEP medication tenofovir disoproxil fumarate/emtricitabine increased from $1350 to $1638 from 2014 to 2018, an average annual increase of 5%. Out-of-pocket costs increased faster from $54 to $94, an average annual increase of 14.9%. In 2018, at least $2 billion was spent paying for the PrEP medication, and this covered 18% of people that had an indication for PrEP.  (more…)
Author Interviews, CDC, COVID -19 Coronavirus, Heart Disease / 25.08.2020

MedicalResearch.com Interview with: Eric J. Chow, MD, MS, MPH Epidemic Intelligence Service Officer (completed in 2020); Influenza Division. Centers for Disease Control and Prevention  MedicalResearch.com: What is the background for this study? What are the main findings?
  • Both heart disease and influenza epidemics cause substantial morbidity and mortality every year. In some seasons, influenza virus infections alone contribute up to 810,000 hospitalizations and 61,000 deaths. There is increasing evidence that there is overlap between infections, specifically influenza, and heart disease. In our study, we sought to describe the frequency and risk factors for acute cardiac events in patients who are hospitalized with influenza.
  • In over 80,000 adults hospitalized with influenza over 8 seasons (2010-2018), almost 12% were diagnosed with acute cardiac events, with acute heart failure and acute ischemic heart disease being the most common.
  • Among patients hospitalized with influenza who experienced acute cardiac events, almost one-third were admitted to the intensive care unit and 7% died while hospitalized.
  • Our study also reaffirmed that people who are older, smoke tobacco or have underlying cardiovascular disease, diabetes and kidney disease are at increased risk for the most common acute cardiac events, acute heart failure and acute ischemic heart disease.
  • Although vaccinated persons had a lower risk of acute ischemic heart disease and acute heart failure, this study was not designed to specifically assess vaccine effectiveness.  However, this and other studies support the importance of influenza vaccines for people with underlying heart conditions.

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, Cannabis, CDC, JAMA, Pediatrics, Tobacco Research / 18.05.2020

MedicalResearch.com Interview with: Susan Hocevar Adkins, MD Lead Author, Senior Medical Officer, and Commander United States Public Health Service CDC MedicalResearch.com: What is the background for this study? Response: Since August 2019, the Centers for Disease Control and Prevention (CDC), the US Food and Drug Administration (FDA), and state, local, and territorial health departments have been investigating a national outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI). Although clinical presentation and outcomes of EVALI patients generally have been reported, data on adolescent patients are more limited. This article fills this gap by using data from national EVALI surveillance at CDC to examine demographic, substance use, and clinical characteristics of adolescent EVALI patients relative to young adult and adult EVALI patients.

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: Snigdha Vallabhaneni, MD, MPH Centers for Disease Control and Prevention Atlanta, GA MedicalResearch.com: What is the background for this study?  Response: We are concerned about the fungus Candida auris (or C. auris) because it causes serious infections, is often resistant to medications, and continues to spread at alarming rates in U.S. healthcare settings. Candida. auris  primarily affects patients in who are hospitalized for a long time or are residents of nursing homes that take care of patients on ventilators. C. auris is still rare in the United States and most people are at low risk of getting infected. People who get C. auris or other Candida infections are often already sick from other medical conditions and often have invasive medical care, including ventilators for breathing support, feeding tubes, central venous catheters, and have received lots of antibiotics. Many patients infected and colonized with C. auris move frequently between post-acute care facilities and hospitals, which increases the risk of spreading C. auris between facilities. (more…)
Author Interviews, CDC, Cost of Health Care, Diabetes / 09.07.2019

MedicalResearch.com Interview with: Xiaohui Zhuo, PhD Division of Diabetes Translation National Center for Chronic Disease Prevention and Health Promotion Centers for Disease Control and Prevention, Atlanta, GA  MedicalResearch.com: What is the background for this study? Response: Prescription drug spending (spending from families and individuals, their medical providers (doctors, hospitals, pharmacies, etc.) and employees across the United States) has increased at a much higher rater than other components of the total medical expenditure associated with diabetes.  The share of spending on prescription drugs in per capita annual excess expenditure due to diabetes increased from 27% to 41% between 1987 and 2011, according to a previous study using national data from the Agency for Healthcare Research and Quality Medical Expenditures Panel Surveys. In this most recent study, CDC researchers estimated the increase in the national spending on antidiabetic drugs from 2005 to 2016 in total and by drug class and broke down the increase in total national spending by examining what factors have contributed to the increase estimating the magnitude of each factor’s contribution.

Author Interviews, CDC, Emory, Infections, JAMA, Pediatrics, Vaccine Studies / 02.07.2019

MedicalResearch.com Interview with: Ms. Cassandra Pingali Ms. Pingali worked on this paper while a a graduate student at Emory University, and completed it post-graduation. She is currently an ORISE fellow at Centers for Disease Control and Prevention Immunization Services Division MedicalResearch.com: What is the background for this study? Response: Despite high overall immunization coverage in the United States, we are currently experiencing the largest measles outbreak since measles was declared eliminated in 2000. In 2014, California grappled with a very large measles outbreak known as the “Disneyland” outbreak. Later investigation revealed that most of the affected children were unvaccinated against measles despite the availability of a safe and effective vaccine. In order to prevent future outbreaks, California officials wanted to improve their declining childhood vaccination coverage. California passed two laws and implemented an educational program for school staff to increase vaccination rates in the state. We felt it was important to take a systematic look at these interventions and examine if public health initiatives such as these are working to improve vaccination rates. (more…)

MedicalResearch.com Interview with: Liping Pan, MD, MPH Epidemiologist Division of Nutrition, Physical Activity, and Obesity National Center for Chronic Disease Prevention and Health Promotion Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? Response: Children with severe obesity face significant health and social challenges. Children with obesity are at higher risk for having other chronic health conditions and diseases, such as asthma, sleep apnea, bone and joint problems, and type 2 diabetes. They also have more risk factors for heart disease such as high blood pressure, impaired glucose tolerance, and high cholesterol than their healthyweight peers. Children with obesity can be bullied and teased more than their healthyweight peers. They are also more likely to suffer from social isolation, depression, and lower self-esteem. Children with obesity are also more likely to have obesity as adults. This can lead to lifelong physical and mental health problems. Adult obesity is associated with a higher risk of type 2 diabetes, heart disease, and many types of cancers.  Childhood obesity is more common among children from lower-income families, as many lack access to healthy, affordable foods and beverages and opportunities for low-cost physical activity.

Author Interviews, CDC, Emergency Care, Occupational Health, Opiods / 02.05.2019

MedicalResearch.com Interview with: Sophia K. Chiu, MD Epidemic Intelligence Service, CDC Division of Surveillance, Hazard Evaluations, and Field Studies National Institute for Occupational Safety and Health CDC  MedicalResearch.com: What is the background for this study? Response:  Responders across the United States are reporting work-related health effects during incidents in which suspected opioids (including fentanyl) and other illicit drugs such as cocaine, methamphetamine, cathinones, and synthetic cannabinoids are present, often as a mixture. These health effects have interfered with responders’ ability to perform their job duties. Since 2018, a number of responder organizations have requested that NIOSH investigate the health effects experienced by emergency responders during these response incidents. These organizations are looking for ways to protect their responders and prevent the symptoms responders have reported experiencing, so that they can in turn better serve the public. NIOSH’s goal is to increase awareness among responders of how they can remain safe while providing the care the public needs. (more…)

MedicalResearch.com Interview with: CDR Andrew Geller, MD Medical Officer, Medication Safety Program Division of Healthcare Quality Promotion, CDC Atlanta GA 30329 MedicalResearch.com: What is the background for this study? Response: There has been a lot of recent attention on drug overdoses in the United States, particularly fatal overdoses which involve opioids. But the overall frequency with which patients end up in the emergency department (ED) due to nonmedical use of medications across the US is unknown.
  • Nonmedical use refers to a spectrum of circumstances, including intentionally using more medication than is recommended in an attempt to treat a health condition (therapeutic misuse) to using medication to attain euphoria or get “high” (abuse).
With this analysis, we wanted to focus on the acute harms to individual patients from nonmedical use of all medications, in order to help target prevention efforts.
  • Specifically, we used data from a nationally-representative sample of hospital EDs to identify the medications with the highest numbers of emergency visits for harms following nonmedical use of medications and to identify the patient groups with the highest risks.

Author Interviews, CDC, JAMA, Opiods / 12.02.2019

MedicalResearch.com Interview with: Gery Guy, PhD, MPH Injury Center CDC MedicalResearch.com: What is the background for this study? Response: This study examined opioid prescribing at the national and county-level in 2015 and 2017. During 2015 to 2017, the amount of opioids prescribed decreased 20.1% in the United States. The amount of opioids prescribed per person varies substantially at the county-level. The average amount of opioids prescribed in the highest quartile of counties was nearly 6 times the amount in the lowest quartile. Reductions in opioid prescribing could be related to policies and strategies aimed at reducing inappropriate prescribing, increased awareness of the risks associated with opioids, and release of the CDC Guideline for Prescribing Opioids for Chronic Pain.

MedicalResearch.com Interview with: Stephen Onufrak, PhD Epidemiologist, Obesity Prevention and Control Branch Division of Nutrition, Physical Activity and Obesity Centers for Disease Control and Prevention Atlanta, GA  MedicalResearch.com: What is the background for this study? Response: With more than 150 million working adults in the United States, workplaces represent a far reaching setting for chronic disease prevention and health promotion. While research suggests that workplace wellness efforts can be effective at changing health behaviors, little is known about the foods that people acquire at work. In this study, we used data from the US Department of Agriculture Food Acquisition and Purchasing Survey (FoodAPS) to investigate workplace food acquisitions among employed adults during a 7 day study period. The foods we examined included those purchased in places like cafeterias and vending machines as well as those acquired for free at meetings, social events, common areas, or shared by coworkers. They did not include foods brought from home by someone to eat at work themselves or food acquired by the employee at offsite restaurants.  (more…)
Author Interviews, CDC, Infections, Pediatrics, Vaccine Studies / 18.01.2019

MedicalResearch.com Interview with: Sarah Anne Mbaeyi MD MPH Division of Bacterial Diseases CDC  MedicalResearch.com: What is the background for this study? Response: College freshman living in residence halls, though not college students overall, have previously been identified as being at increased risk for meningococcal disease. However, these evaluations were conducted in the 1990s when rates of disease were higher, serogroup C was the predominant cause of disease, and before the availability of quadrivalent meningococcal conjugate (MenACWY) or serogroup B meningococcal (MenB) vaccines. MenACWY vaccine is routinely recommended for all adolescents at age 11 years and 16 years, as well as unvaccinated or undervaccinated college freshmen living in residence halls. MenB vaccine is not routinely recommended for all adolescents or college students, but may be administered to persons aged 16-23 years, with the preferred age of 16-18 years, based on clinical decision-making. Meningococcal vaccines are also recommended during an outbreak, and in recent years MenB vaccines have been used during multiple outbreaks on college campuses. In this evaluation, we aimed to describe the current epidemiology of meningococcal disease among college-aged young adults in the United States. (more…)

MedicalResearch.com Interview with: Dr. Srinivas Acharya Nanduri, MBBS, MD, MPH Respiratory Diseases Branch, National Center for Immunizations and Respiratory Diseases Centers for Disease Control and Prevention Roybal Campus Atlanta, GA 3033 MedicalResearch.com: What is the background for this study? Response: Group B Streptococcus (GBS) is a leading cause of serious illness such as meningitis and sepsis in infants. Among infants, there are two main types of GBS disease. Early-onset GBS disease occurs during the first week of life and late-onset GBS disease occurs from the first week through three months of life. Rates of early-onset disease in the United States have decreased significantly since the 1990s through widespread implementation of intrapartum antibiotic prophylaxis (IAP) guidelines. However, IAP does not prevent late-onset disease. Maternal immunization represents a nonantibiotic strategy to prevent both early and late-onset disease. Multivalent polysaccharide-protein conjugate vaccines are under development against GBS capsular types, with candidate vaccines in phase I and II trials. Active Bacterial Core surveillance (ABCs) conducts active surveillance for early and late-onset GBS disease among infants in select counties of 10 states, covering about 10% of live births across the United States. We analyzed data from early and late-onset GBS cases identified from ABCs between 2006 and 2015 to describe their epidemiology, incidence trends, and associated strain characteristics. (more…)

MedicalResearch.com Interview with: Kevin Chatham-Stephens, MD, MPH, FAAP CDR U.S. Public Health Service MedicalResearch.com: What is the background for this study? Response: Typhoid fever is a life-threatening disease caused by Salmonella Typhi bacteria. It spreads when someone consumes food or water that has been contaminated with feces (poop) from someone carrying the bacteria. About 12–27 million cases of typhoid fever occur worldwide every year. About 350 culture-confirmed cases of typhoid fever in the United States are reported to CDC each year. Most of these cases occur among international travelers. Symptoms of typhoid fever often include high fever, weakness, stomach pain, cough, and loss of appetite. Some people have diarrhea or constipation. Typhoid fever can be prevented through vaccination and safe food and water practices. Typhoid fever is treated with antibiotics, although most infections diagnosed in the United States cannot be successfully treated with the class of antibiotics called fluoroquinolones. (more…)

MedicalResearch.com Interview with: "Day 19: Norovirus (stomach flu) visits our home." by Loren Kerns is licensed under CC BY 2.0Rachel M. Burke, PhD, MPH Epidemiologist, Viral Gastroenteritis Branch Centers for Disease Control and Prevention Atlanta, GA 30329 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Noroviruses are the leading cause of vomiting and diarrhea from acute gastroenteritis (inflammation of the stomach or intestines) among people of all ages in the United States. Each year in the United States, norovirus illness is responsible for an estimated 19 to 21 million cases of acute gastroenteritis, and contributes to 56,000 to 71,000 hospitalizations and 570 to 800 deaths, mostly among children and the elderly. CDC linked information from two different surveillance systems to analyze 3,747 norovirus outbreaks reported by health departments from 2009 to 2016. Our study provides a comprehensive description of norovirus outbreaks from the epidemiology and laboratory perspectives, using the National Outbreak Reporting System (NORS) and CaliciNet, respectively.  Norovirus outbreaks caused by GII.4 strains occurred more often in healthcare settings, affected older adults, and caused more severe illness, leading to hospitalization or death.

Author Interviews, CDC, Hospital Acquired / 01.11.2018

MedicalResearch.com Interview with: "Hospital Room" by Kyle Taylor is licensed under CC BY 2.0Dr. Shelley Magill, MD Medical Officer and CDC lead for the hospital HAI (hospital acquired infections) and antimicrobial use prevalence survey MedicalResearch.com: What is the background for this study? Response: The prevalence survey effort began in 2009. The goal was to obtain a snapshot of all healthcare-associated infections affecting hospital patients, not limited to those commonly reported to the National Healthcare Safety Network. We conducted our first full-scale hospital prevalence survey in 2011, in collaboration with the Emerging Infections Program, a network of 10 state health departments and academic and other partners. Data from that survey showed that about four percent of patients had a healthcare-associated infection—or, on any given day, about 1 in 25 patients. We repeated the survey in a similar group of hospitals in 2015 to see whether changes had occurred. (more…)
Author Interviews, CDC, JAMA, Pediatrics, Smoking / 04.10.2018

MedicalResearch.com Interview with: "Electronic Cigarette/E-Cigs/E-Cigarettes" by Chris F is licensed under CC BY 2.0Brian King, PhD Lead author and Deputy Director for Research Translation Office on Smoking and Health. CDC MedicalResearch.com: What is the background for this study? Response: Since first entering the U.S. marketplace in 2007, e-cigarettes have been a rapidly evolving product class. Typically, national surveys provide annual, self-reported estimates of e-cigarette use among adults and youth. However, given the dynamic nature of the e-cigarettes landscape, data collected at a sub-annual level can be useful for identifying rapid changes and patterns. For example, retail sales data, which is available at more frequent intervals, such as weekly, can complement annual surveys and help keep a pulse on emerging trends. This study assessed e-cigarette retail sales data in the United States from 2013 through 2017. (more…)

MedicalResearch.com Interview with: "Siberian Husky Puppies 2013-05-25" by Jeffrey Beall is licensed under CC BY 2.0Mark Laughlin, DVM Veterinary Medical Officer CDC MedicalResearch.com: What is the background for this study? How common are Campylobacter infections?  How does a Campylobacter infection typically present?  Response: Campylobacter is one of the most common causes of diarrheal illness in the United States, causing an estimated 1.3 million illnesses each year. Most people with Campylobacter infection usually have diarrhea (often bloody), fever, and abdominal cramps. The diarrhea may be accompanied by nausea and vomiting. These symptoms usually start within 2 to 5 days after exposure and last about a week. Most illnesses from Campylobacter likely occur due to eating raw or undercooked poultry, or from eating something that touched raw or undercooked poultry. Some illnesses can occur from contact with contaminated water, contact with animals, or from drinking raw (unpasteurized) milk. Since 2009, 13 outbreaks of human Campylobacter infections linked to contact with dogs have been reported to CDC. These outbreaks account for a reported 47 illnesses and 2 hospitalizations. (more…)
