Author Interviews, Cancer Research, CDC / 15.08.2017

MedicalResearch.com Interview with: Mary C. White, ScD MPH Epidemiology and Applied Research Branch Division of Cancer Prevention and Control CDC Atlanta GA 30341 MedicalResearch.com: What is the background for this study? Response: Most cancers are caused not by just one thing, but instead by a combination of different factors over many years. Early adulthood is a time of many life changes and stresses, and exposure to harmful products and unhealthy habits during early adulthood can set the stage for developing cancer at older ages. We analyzed responses from a national sample of young adults to questions about diet, physical activity, tobacco products, alcohol, indoor tanning, sleep, the HPV vaccine, and obesity. These factors have been linked to higher risks of different types of cancer. (more…)
Annals Internal Medicine, Author Interviews, CDC, HIV / 09.08.2017

MedicalResearch.com Interview with: Dr. Nicole Crepaz PhD Behavioral Scientist Division of HIV/AIDS Prevention CDC MedicalResearch.com: What is the background for this study? Response: The most common measure of viral suppression in clinical and surveillance studies is the most recent viral load in past 12 months. This single-value measure does not capture the viral load dynamics over time. We examined durable viral suppression, never virally suppressed, and cumulative HIV burden (measured in the viremia copy-year) to help us better understand viral suppression and transmission risk potential.

Author Interviews, CDC, Gender Differences, HIV / 07.08.2017

MedicalResearch.com Interview with: Dr. Tiffany Aholou Behavioral Scientist Division of HIV/AIDS Prevention CDC MedicalResearch.com: What is the background for this study? Response: Women accounted for 24% of people living with HIV in the United States at the end of 2013 and 19% of HIV diagnoses in 2014. Of these diagnoses, 78% were among black women and Latinas. HIV diagnoses among women are overwhelmingly attributed to heterosexual contact with a person known to have, or to be at high risk for, HIV infection. Of note, new HIV diagnoses among US women declined 40% over a 10 year period (2005-2014), yet we continue to see significant racial/ethnic disparities due largely to a complex web of demographic, individual, social and contextual factors with the environment that enables HIV risk behaviors to occur. While the decline in new HIV diagnoses among US women is noteworthy, in our review of the literature, we found research studies that specifically focus on women and HIV from a domestic perspective were scarce. To fill this gap and sharpen our understanding about sexual behaviors that are associated with heterosexual transmission of HIV, this study used data from three cycles of the National Survey of Family Growth (2006-2008, 2008-2010, and 2011-2013) to examine HIV-related sexual risk and protective behaviors - concurrent sex partnerships, non-monogamous sex partners, and condom use at either last vaginal sex or anal sex similar to what you might of seen on websites such as fulltube xxx - among sexually active women aged 18-44 years by race/ethnicity and over time.

MedicalResearch.com Interview with: EmikoPetrosky MD M.P.H Science Officer, National Violent Death Reporting System at Centers for Disease Control and Prevention Centers for Disease Control and Prevention Emory University Rollins School of Public Health MedicalResearch.com: What is the background for this study? Response: Homicide is one of the leading causes of death for women aged 44 years and younger. In 2015, 3,519 girls and women died by homicide in the United States.  It is the 5th leading cause of death for women under 45 years age (defining women as 18-44 years of age). The National Violent Death Reporting System (NVDRS) links together data from death certificates, coroner/medical examiner reports, and law enforcement reports, resulting in more information about the circumstances of death than what is available elsewhere.

Author Interviews, CDC, OBGYNE, Pediatrics, Race/Ethnic Diversity / 17.07.2017

MedicalResearch.com Interview with: Dr. Erica H. Anstey PhD Division of Nutrition, Physical Activity and Obesity National Center for Chronic Disease Prevention and Health Promotion Immunization Services Division National Center for Immunization and Respiratory Diseases CDC MedicalResearch.com: What is the background for this study? Response: The American Academy of Pediatrics (AAP) recommends that infants are breastfed exclusively for about the first 6 months and that breastfeeding continue for at least 12 months, and thereafter for as long as mother and baby desire. Although breastfeeding initiation and duration rates have increased overall in the United States, breastfeeding rates vary by geographic location, socioeconomic, and race/ethnic groups. Breastfeeding initiation and duration have been historically and consistently lower among black infants compared with white and Hispanic infants. There are many factors that influence a woman’s decision to start and continue breastfeeding. These include knowledge about breastfeeding, cultural and social norms, family and social support, and work and childcare environments. Some barriers to breastfeeding are disproportionately experienced by black women, including earlier return to work, inadequate receipt of breastfeeding information from providers, and lack of access to professional breastfeeding support.

MedicalResearch.com Interview with: Deborah Dowell, MD, MPH Chief Medical Officer, Division of Unintentional Injury Prevention National Center for Injury Prevention and Control Centers for Disease Control and Prevention  MedicalResearch.com: What is the background for this study? Response: CDC analyzed retail prescription data from QuintilesIMS which provides estimates of the number of opioid prescriptions dispensed in the United States from approximately 59,000 pharmacies, representing 88% of prescriptions in the United States. CDC assessed opioid prescribing in the United States from 2006 to 2015, including rates, amounts, dosages, and durations prescribed. CDC examined county-level prescribing patterns in 2010 and 2015.

Author Interviews, Cancer Research, CDC / 07.07.2017

MedicalResearch.com Interview with: Lisa C. Richardson, MD, MPH, Oncologist Director,Division of Cancer Prevention and Control CDC MedicalResearch.com: What is the background for this study? Response: This MMWR report is the first complete description of cancer incidence and mortality comparing rural and urban America.  From previous reports we know that rural residents are more likely to be older, have more comorbid conditions and participate in high risk behaviors that can lead to cancer. CDC researchers were interested in how these factors were related to new cancers and cancer deaths in rural counties compared to metropolitan counties. Researchers found that rates of new cases for lung cancer, colorectal cancer, and cervical cancer were higher in rural America. In contrast, rural areas were found to have lower rates of new cancers of the female breast, and prostate. Rural counties had higher death rates from lung, colorectal, prostate, and cervical cancers.

Author Interviews, CDC, Exercise - Fitness, JAMA / 04.07.2017

MedicalResearch.com Interview with: Emily Neusel Ussery, MPH PhD Epidemiologist, Physical Activity and Health Branch CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Walking is an easy way for most people to start and maintain a physically active lifestyle. Step It Up! The Surgeon General’s Call to Action to Promote Walking and Walkable Communities identifies walking as an important public health strategy to increase physical activity levels in the U.S. A previous report found that the percentage of adults who reported walking for transportation or leisure increased by 6 percentage points between 2005 and 2010, but it is unknown if this increase has continued. This report examined trends in the proportion of U.S. adults who reported walking for transportation or leisure for at least one 10-minute period in the past week, using nationally representative data from the 2005, 2010, and 2015 National Health Interview Surveys. We also examined differences in walking trends by sociodemographic characteristics. If you take walking seriously, make sure you invest in some custom boots to make sure you don't damage your feet. For those who need to transport larger items while walking isn't an option, utilizing a Large Item Courier service can help ensure safe and efficient delivery. (more…)
Author Interviews, CDC, Occupational Health / 28.06.2017

MedicalResearch.com Interview with: Taylor M. Shockey MPH CDC/National Institute for Occupational Safety and Health CDC MedicalResearch.com: What is the background for this study? Response: Our study examined health-related quality of life (HRQOL) among 22 major occupation groups using the Behavioral Risk Factor Surveillance System (BRFSS) data. The BRFSS is an annual telephone survey that collects data from U.S. residents on their health-related risk behaviors, chronic health conditions, and use of preventive services. HRQOL is an individual’s self-perception of their physical and mental health over time and it provides a valuable measure of well-being. HRQOL is used by a variety of different fields, outside of public health, including psychology, social work, economics, and urban planning. HRQOL is a measure capable of linking these different fields and is used to determine disease burden, to monitor progress in achieving the Healthy People goals, to guide policy and legislation, to develop interventions, and to allocate resources where they are most needed. The Healthy People goals are 10-year targets for improving the health of Americans through health promotion activities and disease prevention efforts. In relation to occupation, prior research that has evaluated HRQOL has typically focused on employment status, but not on specific job type. It’s been established, however, that job characteristics such as high demand, low control, role stress, bullying, work hours, etc., are associated with greater risk for common mental health problems as well as physical outcomes like headaches, fatigue, and gastrointestinal problems. Our study wanted to determine if differences in HRQOL would exist among occupation groups. (more…)
Author Interviews, CDC, Lyme / 23.06.2017

MedicalResearch.com Interview with: Dr. Christina Nelson, MD MPH Medical epidemiologist, Division of Vector-Borne Diseases CDC  MedicalResearch.com: What is the background for this study? Response: Patients who are given a diagnosis of “chronic Lyme disease” have been offered a variety of treatments that have not been shown to be effective.  Many patients are treated with prolonged courses of antibiotics (for months or years), which have not been shown to provide substantial long-term benefit to patients.  Anecdotal reports about adverse outcomes associated with these treatments for chronic Lyme disease are common, but there have not been systematic efforts to collect data about the frequency of these events. MedicalResearch.com: Why is the diagnosis of 'Chronic Lyme Disease' so common? Response: The term “chronic Lyme disease” (CLD) has been used to describe people with different illnesses. While the term is sometimes used to describe illness in patients with Lyme disease, in many occasions it has been used to describe symptoms in people who have no evidence of a current or past infection with Lyme disease.  Because of the confusion in how the term CLD is employed, experts in this field do not support its use.

MedicalResearch.com Interview with: Elizabeth A. Soda, MD Epidemic Intelligence Service Divison of Bacterial Diseases National Center of Immunization and Respiratory Diseases CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: Legionella is a waterborne bacterium responsible for Legionnaires’ disease, an often severe pneumonia. Legionnaires’ disease primarily affects certain groups of individuals such as those ≥50 year of age, current or former smokers, and those with chronic diseases or weakened immune systems. Health care facilities often have large and complex water systems and care for vulnerable populations that are susceptible to developing Legionnaires’ disease. Thus preventing hospitalized patients from developing Legionnaires’ disease is the ultimate goal. This analysis aimed to describe health care-associated Legionnaires’ disease in 2015 from the 21 U.S. jurisdictions that completely reported their health care-associated Legionnaires’ disease cases to the CDC’s Supplemental Legionnaires’ Disease Surveillance System (SLDSS). Over 2,800 cases of Legionnaires’ disease cases were reported to SLDSS by the 21 jurisdictions, and 553 (20%) were considered health care associated. The analysis showed 16 of the 21 (76%) jurisdictions had at least one case of Legionnaires’ disease definitely related to a stay in a hospital or long-term care facility. In total there were 85 (3%) definite health care-associated Legionnaires’ disease cases (as defined by continuous exposure to a hospital or long-term facility for the entire 10 days before symptom onset) that resulted from 72 different health care facilities. Additionally, 20 of 21 jurisdictions (95%) reported 468 (17%) possible health care-associated Legionnaires’ disease cases (as defined by any exposure to a health care facility for a portion of the 10 days before symptom onset) that resulted from approximately 415 different health care facilities. While approximately 9% of Legionnaires’ disease cases overall are fatal, this report showed a case fatality of 25% for definite health care-associated cases. (more…)
Author Interviews, CDC, Flu - Influenza, OBGYNE, Vaccine Studies / 31.05.2017

MedicalResearch.com Interview with: Dr. Elyse Olshen Kharbanda, MD MPH HealthPartners Institute Minneapolis, MN MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pregnant women who get the flu are at an increased risk for severe illness. To protect pregnant women, the Advisory Committee on Immunization Practices recommends women receive inactivated influenza vaccine (IIV) during any trimester of their pregnancy. This study used data from the Vaccine Safety Datalink to evaluate if there was an increased risk for selected major structural birth defects for infants whose mothers received IIV in the first trimester of pregnancy versus infants who were unexposed to IIV. Among over 425,000 live births, including 52,856 whose mothers received IIV during first trimester, we evaluated risks for major structural birth defects.  In this large observational study, we did not observe increased risks for major structural birth defects in offspring following first trimester maternal inactivated influenza vaccine exposure.

MedicalResearch.com Interview with: Dr. Jorge Salinas MD Epidemic intelligence service officer Division of Tuberculosis Elimination Centers for Disease Control and Prevention  MedicalResearch.com: What is the background for this study? Response: Because multidrug-resistant TB (MDR TB) treatment regimens are less effective, more complex, and are more likely to have side effects that are difficult to tolerate than regimens for drug-susceptible TB, patients with MDR TB are at a higher risk of dying. Directly observed therapy (a therapy by which patients meet with a healthcare worker at a regularly scheduled time and place so the healthcare worker can observe the patient taking their TB medication) is recommended to treat all forms of TB disease, including MDR TB.

MedicalResearch.com Interview with: Anup Srivastav, DVM, MPVM, PhD National Center for Immunization and Respiratory Diseases (NCIRD) Centers for Disease Control and Prevention Atlanta GA MedicalResearch.com: What is the background for this study? Response: Healthcare personnel (HCP) are at risk for being exposed to pertussis (whooping cough) and spreading the disease to patients in their work settings. CDC recommends tetanus, diphtheria, acellular pertussis (Tdap) vaccination for healthcare personnel to reduce their risk of getting the disease and spreading it to patients. This is the first report of Tdap vaccination coverage among healthcare personnel by occupational setting. (more…)
Author Interviews, CDC, Rheumatology / 13.05.2017

MedicalResearch.com Interview with: Jin Qin, ScD, MS Epidemiologist Centers for Disease Control and Prevention Chamblee, GA 30341  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The hand is one of the sites most commonly affected by osteoarthritis (OA) but is often understudied compared with knee and hip OA. Many people with hand OA have significant symptoms, impaired hand strength and function, and disability in activities of daily living, like using a smart phone or a computer keyboard, and opening a jar. Lifetime risk is the probability of developing a condition over the course of a lifetime. In this study, we estimated that 40% of adults will develop symptomatic hand OA in their lifetimes. Nearly one in two women (47%) and one in four men (25%) will develop the condition. Whites have a 41% lifetime risk, compared with 29% for blacks. The lifetime risk among individuals with obesity is 47%, which is 11 percentage points higher than those without obesity. (more…)
Author Interviews, Breast Cancer, CDC, Cost of Health Care / 03.05.2017

MedicalResearch.com Interview with: Benjamin Allaire MS RTI International Research Triangle Park Durham, NC, 27709 MedicalResearch.com: What is the background for this study? Response: More than 22,000 women younger than 45 years of age were diagnosed with breast cancer in 2013. Although less than 10 percent of all breast cancers are diagnosed among women younger than age 45, the types of breast cancer these younger women face are typically more aggressive, are diagnosed at more advanced stages, and result in poorer survival compared to breast cancer in older women. Younger women may also require more intense treatment, exhibit cancers that are less responsive to treatment, and have distinct and more prevalent side effects from treatment than older women. These side effects can include poorer quality of life, fertility problems, and depression. As a result, breast cancer treatment for younger women is expensive, making them vulnerable to financial hardship. Recent research has shown that 31.8 percent of cancer survivors are likely to have cancer treatment-induced financial troubles, with higher rates among younger cancer patients. These financial difficulties cause some survivors to forego or delay necessary medical treatments. (more…)
Aging, Author Interviews, Cancer Research, CDC, OBGYNE / 03.05.2017

MedicalResearch.com Interview with: Mary C. White, ScD Epidemiology and Applied Research Branch Division of Cancer Prevention and Control, CDC Atlanta GA 30341 MedicalResearch.com: What is the background for this study? Response: For women between the ages of 21 to 65, Pap testing every three years, or Pap testing with HPV co-testing every five years, can prevent cervical cancers and deaths. Current recommendations state that women 65 and older and not otherwise at special risk can skip Pap tests, but only if they have had three consecutive negative Pap screening tests or two consecutive negative co-tests over the past 10 years, with the most recent done within the past five years. We used data from two federal cancer registry programs to examine how cervical cancer risk changes with age, after excluding women who have had a hysterectomy. We also examined data from a federal national health survey to examine the proportion of women who either had never been tested or had not been tested in the last 5 years. (more…)
Author Interviews, CDC, OBGYNE, Pediatrics / 01.05.2017

MedicalResearch.com Interview with: Deborah L. Dee, PhD Division of Reproductive Health National Center for Chronic Disease Prevention and Health Promotion CDC MedicalResearch.com: What is the background for this study? Response: Although the national teen birth rate has dropped to a historic low (22.3 births per 1,000 females aged 15-19 years in 2015), many teens continue to have repeat births. Because repeat teen births are more likely than first teen births to be preterm and low birth weight, and giving birth more than once as a teenager can significantly limit a mother’s ability to attend school and obtain work experience, it’s important to assess patterns in repeat teen births and better understand contraceptive use within this population.

Author Interviews, CDC, Infections / 22.04.2017

MedicalResearch.com Interview with: Ms. Ellyn Marder MPH Surveillance Epidemiologist, CDC Centers for Disease Control and Prevention Atlanta, Georgia MedicalResearch.com: What is the background for this study? What are the main findings? Response: CDC’s Foodborne Diseases Active Surveillance Network (FoodNet) report provides the most up-to-date information about foodborne illnesses in the United States. Each year, FoodNet publishes a report that includes preliminary data compared with data from the previous three years. FoodNet has been monitoring illness trends since 1996 and collects data on about 15 percent of the U.S. population. Campylobacter and Salmonella caused the most reported bacterial foodborne illnesses in 2016, according to preliminary data. FoodNet sites alone reported 24,029 foodborne infections, 5,512 hospitalizations, and 98 deaths in 2016. The numbers of reported illnesses by germ are: Campylobacter (8,547), Salmonella (8,172), Shigella (2,913), Shiga toxin-producing E. coli (1,845), Cryptosporidium (1,816), Yersinia (302), Vibrio (252), Listeria (127) and Cyclospora (55). This is the first time the report also includes in the total number of infections those foodborne bacterial infections diagnosed only by rapid diagnostic tests in FoodNet sites. Previously, the report counted foodborne bacterial infections confirmed only by traditional culture-based methods in the total numbers. (more…)
Author Interviews, CDC, JAMA, Stroke / 10.04.2017

MedicalResearch.com Interview with: Mary G. George, MD, MSPH Division for Heart Disease and Stroke Prevention 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: Stroke is the fifth leading cause of death in the United States, killing more than 130,000 Americans each year—that’s 1 of every 20 deaths—and costs the nation $33 billion annually, including the cost of health care services, medications, and lost productivity. And, stroke is leading cause of serious disability. An ischemic stroke, sometimes called a brain attack, is a stroke that occurs when there is a blockage of the blood supply to the brain. (more…)
Author Interviews, CDC, Global Health, Vaccine Studies / 10.04.2017

MedicalResearch.com Interview with: Deborah Lee, MPH Division of Global Migration and Quarantine Centers for Disease Control and Prevention, Atlanta, GA MedicalResearch.com: What is the background for this study? What are the main findings? Response: We wanted to assess whether documentation for vaccines provided to refugees overseas was received by clinicians in the US and if doses of measles-mumps-rubella (MMR) vaccine were integrated into the vaccine schedule as recommended for adults and children by the US Advisory Committee on Immunization Practices. CDC recommends that US-bound refugees receive vaccinations prior to arrival in the United States. Vaccinations are documented on the Vaccination Documentation Worksheet (DS-3025), which refugees bring with them to the United States, and made available to state and local refugee health programs through CDC’s Electronic Disease Notification (EDN) system. Thirty to 90 days after arrival, most refugees have a post-arrival health assessment performed by clinicians affiliated with the state and local refugee health programs. Our assessment indicated that most refugees had overseas vaccination documentation available at the post-arrival health assessments (87%), and that MMR vaccine was given when needed (83%). Furthermore, many refugees (90%) in our assessment did not require an additional MMR dose because they had received vaccination before entering the United States. (more…)
Author Interviews, CDC, HIV, Sexual Health / 23.03.2017

MedicalResearch.com Interview with: Qian An, PhD Epidemiologist/statistician Division of HIV/AIDS Prevention CDC MedicalResearch.com: What is the background for this study? Response: Since 2006, the Centers for Disease Control and Prevention (CDC) has recommended HIV testing for all persons aged 13-64 years old. Persons at high risk for HIV infection should be tested more frequently. Among sexually active men who have sex with men (MSM), repeat testing is recommended at least annually. An analysis in 2011 suggested that MSM might benefit from more frequent than annual testing.(1) Among non-MSM, repeat testing is recommended at least annually for persons at high risk, including persons who inject drugs (PWID) and their sex partners, those who have sex in exchange for money or drugs, heterosexuals who have had more than one sex partner since their most recent HIV test, and those whose partners are living with HIV.. Using statistical models based on renewal theory, we estimate the mean HIV inter-test interval (ITI) — meaning the average time period (in months) between two successive HIV tests — to describe temporal trends in HIV testing frequency among MSM, PWID and high-risk heterosexuals (HRH) and differences in testing frequency by age and race/ethnicity. A decrease in ITI means individuals are testing more frequently. (more…)
Author Interviews, CDC, Smoking, Tobacco, Tobacco Research / 21.03.2017

MedicalResearch.com Interview with: Kristy Marynak, Master of Public Health Public Health Analyst at Centers for Disease Control and Prevention Centers for Disease Control and Prevention Duke University MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for our study is that in recent years, self-reported cigarette smoking has declined among youth and adults, while electronic cigarette (e-cigarette) use has increased. However, sales trends for these products are less certain. Our study assessed national and state patterns of U.S. cigarette and e-cigarette unit sales using retail scanner data from convenience and grocery stores; mass merchandisers like Walmart; drug, dollar, and club stores; and military commissaries.

Author Interviews, CDC, Opiods, Pain Research / 19.03.2017

MedicalResearch.com Interview with: Anuj Shah (B.Pharm) Doctoral Student Division of Pharmaceutical Evaluation and Policy University of Arkansas for Medical Sciences MedicalResearch.com: What is the background for this study? Response: The CDC guideline on opioid prescribing, published in March 2016, included recommendations for initiation of opioid therapy. The guideline noted that there is a lack of data describing how acute opioid use transitions to long-term opioid use. This report seeks to address this gap by determining characteristics of initial opioid prescribing prognostic of long-term use, among opioid naïve cancer-free adults. (more…)
Author Interviews, CDC, Dermatology, Education, Environmental Risks, JAMA / 16.03.2017

MedicalResearch.com Interview with: Sherry Everett Jones PhD, MPH, JD, FASHA Health Scientist, Division of Adolescent School Health Centers for Disease Control & Prevention MedicalResearch.com: What is the background for this study? What are the main findings? Response: Skin cancer is the most common form of cancer in the United States. Results from the School Health Policies and Practices Study found that in 2014, most schools lacked practices that could protect children and adolescents from sun exposure while at school. Positive attitudes and beliefs about sun safety behavior, which would make such behavior more likely, can be promoted and supported by school system policies and practices. (more…)
Author Interviews, CDC, Dermatology, Environmental Risks, JAMA, Melanoma / 07.03.2017

MedicalResearch.com Interview with: Gery P. Guy Jr., PhD, MPH Senior Health Economist Division of Unintentional Injury CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: The incidence of skin cancer is increasing in the United States, and individuals who indoor tan are at an increased risk of skin cancer. Treating skin cancer costs $8.1 billion annually. The number of high school students who indoor tan dropped by half from 2009 to 2015. In 2015, 1.2 million high school students indoor tanned, down from 2.5 million in 2009. This is a much bigger decrease than we have seen in the past and is an encouraging finding. We also found that 82% of indoor tanners reported sunburn in the past year compared with 54% of those who did not engage in indoor tanning. (more…)
Author Interviews, CDC, Fertility, Sexual Health, STD / 01.03.2017

MedicalResearch.com Interview with: Dr. Kristen Kreisel PhD Epidemiologist at Centers for Disease Control and Prevention Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pelvic inflammatory disease (PID), an infection of the female reproductive tract often associated with STDs, is putting millions of women at risk for infertility, ectopic pregnancy and chronic pelvic pain. Our study looked at data from the National Health and Nutrition Examination Survey to estimate the national burden of PID. Findings show an estimated 4.4 percent of sexually-experienced women aged 18-44, or approximately 2.5 million woman nationwide reported a history of PID. (more…)
Author Interviews, CDC, NEJM, Zika / 16.02.2017

MedicalResearch.com Interview with: Gabriela Paz-Bailey MD PhD Senior Epidemiologist Centers for Disease Control and Prevention  MedicalResearch.com: What is the background for this study? Response: Zika virus is recognized as a cause of microcephaly and other severe birth defects when a woman is infected during pregnancy. Additionally, it has been associated with potentially fatal complications, such as Guillain-Barré syndrome. It is not well understood how often Zika virus particles can be detected in semen and other body fluids and for how long they remain detectable. Existing evidence is based on case reports and cross-sectional observations, primarily from returning travelers. A more comprehensive description of the dynamics of the early stages of Zika virus infection, observed within infected people over time, is needed to inform diagnostic testing as well as prevention recommendations and interventions. (more…)
Author Interviews, CDC, Hepatitis - Liver Disease / 15.02.2017

MedicalResearch.com Interview with: Cheryl Isenhour, DVM, MPH Epidemiologist |Prevention Branch Division of Viral Hepatitis | NCHHSTP Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? Response: It is estimated that there are over 3 million people in the United States living with Hepatitis C virus (HCV) infection. Risk factors for infection include, but are not limited to, injection drug use, history of incarceration, HIV coinfection, and blood transfusion prior to July 1992. Several direct acting antiviral medications have recently been approved to treat, and in the majority of cases, cure HCV. The first step in identifying infected persons so that they may be cured of this infection is a blood test for antibodies to HCV. The greatest burden of HCV is among persons born from 1945 through 1965; the baby boomer birth cohort. Therefore, in 2012, the Centers for Disease Control and Prevention (CDC) published updated HCV antibody testing recommendations to include one-time testing of persons in the birth cohort. The United States Preventive Services Task Force (USPSTF) published similar recommendations the following year. Additionally, in recent years there has been an increase in HCV infections related to injection drug use among younger people. We used commercial insurance claims data to describe trends in HCV antibody testing over a 10-year period (2005 – 2014), both to assess the impact of the CDC and USPSTF testing recommendations, and to better understanding how trends varied by gender, age group, and geography.
