MedicalResearch.com Interview with: [caption id="attachment_51918" align="alignleft" width="158"]John W. Ayers, PhD, MA Vice Chief of Innovation | Assoc. Professor Div. Infectious Disease & Global Public Health University of California San Diego Dr. Ayers[/caption] John W. Ayers, PhD, MA Vice Chief of Innovation | Assoc. Professor Div. Infectious Disease & Global Public Health University of California San Diego MedicalResearch.com: What is the background for this study? Response: Touted as a “cure all,” researchers have documented unfounded claims that  cannabidiol (CBD) treats acne, anxiety, opioid addiction, pain, and menstrual problems. You can buy CBD droplets, massage oils, CBD gummies, or even ice cream. But public health leaders have been mostly silent on the subject because they lacked data that demonstrates just how popular CBD is and the future trajectory might be. To fill this data-gap we analyzed Google search queries that mentioned “CBD” or “cannabidiol” emerging from the United States from January 2004 through April 2019 and forecasted searches through December 2019. Rather than relying on self reports, where some might not be willing to discuss CBD openly, our strategy allowed us to directly observed millions of instances of people seeking out information or even shopping for CBD online.

MedicalResearch.com Interview with: Mitsuyoshi Urashima MD, PhD, MPH Professor of Molecular Epidemiology Jikei University School of Medicine Tokyo, JAPAN MedicalResearch.com: What is the background for this study? Response: IgE-mediated food allergy is becoming a global concern, because its prevalence and severity are worsening. Many Japanese maternity wards encourage breastfeeding, but allow mothers or nurses to supplement breastfeeding with cow’s milk formula, e.g., approximately 6 to 10 hours after birth or even earlier, based on maternal preferences, but not based on clinical evidence. However, more than 20 to 30 years ago, sugar water was given instead of cow’s milk formula supplement at birth. Thus, we hypothesized that early exposure to cow’s milk formula at birth is, at least in part, associated with the recent increase in children with food allergy. Therefore, a randomized clinical trial, named ABC (Atopy induced by Breast feeding or Cow's milk formula), was conducted to assess whether the risk of cow’s milk formula sensitization and food allergy is decreased by either avoiding or supplementing cow’s milk formula at birth. Immediately after birth, newborns were randomly assigned (1:1 ratio) to either breastfeeding with or without amino acid-based elemental formula for at least the first 3 days of life (breastfeeding ± elemental formula), or breastfeeding supplemented with cow’s milk formula (≥5 mL/day) from the first day of life to 5 months of age (breastfeeding + cow's milk formula).

MedicalResearch.com Interview with: https://skin-analytics.com/about-us/ Dr. Helen Marsden PhD Skin Analytics Limited London, United Kingdom MedicalResearch.com: What is the background for this study? Response: In this technology age, with the explosion of interest and applications using Artificial Intelligence, it is easy to accept the output of a technology-based test - such as a smartphone app designed to identify skin cancer - without thinking too much about it. In reality, technology is only as good as the way it has been developed, tested and validated. In particular, AI algorithms are prone to a lack of “generalisation” - i.e. their performance drops when presented with data it has not seen before. In the medical field, and particularly in areas where AI is being developed to direct a patient’s diagnosis or care, this is particularly problematic. Inappropriate diagnosis or advice to patients can lead to false reassurance, heightened concern and pressure on NHS services, or worse. It is concerning, therefore, that there are a large number of smartphone apps available that provide an assessment of skin lesions, including some that provide an estimate of the probability of malignancy, that have not been assessed for diagnostic accuracy. Skin Analytics has developed an AI-based algorithm, named: Deep Ensemble for Recognition of Malignancy (DERM), for use as a decision support tool for healthcare providers. DERM determines the likelihood of skin cancer from dermoscopic images of skin lesions. It was developed using deep learning techniques that identify and assess features of these lesions which are associated with melanoma, using over 7,000 archived dermoscopic images. Using these images, it was shown to identify melanoma with similar accuracy to specialist physicians. However, to prove the algorithm could be used in a real life clinical setting, Skin Analytics set out to conduct a clinical validation study.

MedicalResearch.com Interview with: Stephen J. Galli, MD Mary Hewitt Loveless, MD Professor Professor of Pathology and of Microbiology and Immunology Department of Pathology Stanford University School of Medicine Center for Clinical Sciences Research Stanford, CA and Nicolas Gaudenzio PhD Unité de Différenciation Epithéliale et Autoimmunité Rhumatoïde INSERM, Université de Toulouse Toulouse, France MedicalResearch.com: What is the background for this study? What are the main findings? Response: We took a lead from existing clinical data showing that patients with moderate to severe atopic dermatitis, an increasingly common disorder producing skin pathology, also have elevated levels of neuropeptides in their blood, particularly one neuropeptide, named “substance P”, whose level is correlated with disease severity. These patients also have high levels of mast cell-specific proteases in the blood, indicating that mast cells, which are innate immune cells present in the skin, and which can be activated when exposed to substance P, might play an essential role in modulating inflammatory and allergic processes. Based on these observations, our teams (Galli Lab at Stanford University, USA and Gaudenzio Lab at Inserm Toulouse, France) decided to focus on the possible interactions between sensory neurons, which are a source of substance P, and mast cells. The results of this work have now been published in the journal Nature Immunology.

What are the main findings?  Response: Professional burnout is very common among health care providers and is frequently associated with poor quality of care in the published literature. However, we know that reporting biases are common in many fields of literature, and these biases typically result in exaggerated effects being published relative to the true effect. Research on burnout and quality of care appears especially vulnerable, because many studies are not pre-specified or have several potential methods of analysis. If the studies or analyses with more impressive results are more likely to be published, this would result in a skewed picture of the relationship between burnout and quality of care.

What are the main findings?  Response: We know that tanning beds are harmful: people who use tanning beds are more likely to get skin cancer. Sexual minority men are much more likely to use tanning beds and also more likely to get skin cancer. In a separate study we discovered that one reason sexual minority men use tanning beds is if it is convenient: e.g. if close to home, cheap, and easy. (https://onlinelibrary.wiley.com/doi/abs/10.1111/bjd.17684). Recent research showed that tobacco retailers cluster in LGB neighborhoods: https://sph.unc.edu/sph-news/more-tobacco-retailers-in-lgbt-neighborhoods-may-explain-smoking-disparities/. This made us wonder if tanning salons also cluster in neighborhoods with more gay men.

Response: Although marijuana is still classified as a Schedule I drug at the Federal level, as of June 2019, 33 states and the District of Columbia have legalized one or more forms of marijuana; 11 states and the District of Columbia have approved both medical and recreational uses. Public opinion on marijuana has changed dramatically over the last two decades and support for legalization has doubled since 2010. However, very little is known about the prevalence and patterns of marijuana use among adults with medical conditions. This study analyzed the 2016 and 2017 Behavioral Risk Factor Surveillance System data to report the prevalence and patterns of marijuana use among adults with self-reported medical conditions.

What are the main findings?  Response: The identification of BRCA1/BRCA2 pathogenic variants in women susceptible to breast or ovarian cancer in the 1990s created an opportunity for targeted, individualized cancer prevention. BRCA testing in young women before cancer onset enables early detection of those with increased cancer risk and creates an opportunity to offer life-saving prophylactic procedures and medication. We used insurance claims data to assess the use of BRCA testing in unaffected young women <40 years of age between 2006 and 2017 and found that BRCA testing among cancer-free women under 40 has more than doubled in recent years. However, only about 25% of all BRCA testing done in 2017 was performed in unaffected young women under 40.

Gardner professor of clinical gynecology, Vice chair of clinical research Department of Obstetrics and Gynecology Professor of preventive medicine and medical social sciences Northwestern University Feinberg School of Medicine  MedicalResearch.com: What is the background for this study? Response: Asymptomatic bacteriuria, or ASB, is when someone has bacteria in their urine but does not have any signs or symptoms of a urinary tract infection. For pregnant people, this can be a major health concern resulting in severe, even life-threatening, infections that can lead to serious harms for both the mother and the baby. The Task Force’s primary finding in updating its recommendation on this topic was that screening for ASB continues to be beneficial in preventing complications and preserving the health of mothers and their babies during pregnancy.

Response: Psychotic experiences, such as hallucinations and delusions, are features of mental health disorders, such as schizophrenia and bipolar disorder, but they are also reported by approximately 5%-10% of the general population. Psychotic experiences are only considered to be symptoms of mental illness if there are other symptoms of that disorder. It is currently unclear what the genetic causes of psychotic experiences in the general population are, and whether these causes are related to the genetic causes of schizophrenia and other mental health disorders. Given that psychotic experiences are one of the key symptoms of schizophrenia, they may be more closely related than with other mental health conditions such as depression.

Choi, MD, DrPH Professor of Medicine, Harvard Medical School Director, Gout and Crystal Arthropathy Center Director, Clinical Epidemiology and Health Outcomes Division of Rheumatology, Allergy, and Immunology Department of Medicine, Massachusetts General Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Allopurinol is a very common and generally safe medication prescribed to lower serum urate levels, most commonly to patients with gout. However, it can be associated with very rare but serious cutaneous adverse events which includes Stevens-Johnson syndrome and toxic epidermal necrolysis. Prior studies have demonstrated several risk factors for these types of cutaneous adverse events, including presence of chronic kidney disease, older age, female sex, higher initial dose of allopurinol, and the HLA-B*5801 allele, which is more commonly found in Asians and Black patients. A prior study in Taiwan suggested that heart disease (ischemic heart disease and heart failure) may also be associated with an increased risk of hospitalizations for these cutaneous adverse reactions related to allopurinol. Thus, our goal was to investigate this association using a general population cohort from Canada. Using Population Data BC, we found that heart disease was in fact independently associated with an increased risk of hospitalization for these cutaneous adverse reactions.

MedicalResearch.com Interview with: Naomi E Aronson, MD, FIDA, FACP Professor and Director, Infectious Diseases Division Uniformed Services University of the Health Sciences Bethesda, MD  MedicalResearch.com: What is the background for this study? Response: BCG is a live attenuated mycobacteria vaccine used to prevent tuberculosis which has been reported to have associated nonspecific effects such as treatment of diabetes, bladder cancer, prevention of severe respiratory infections in children, and suppressed autoimmune responses. In earlier reports in the 1970s, results of epidemiologic studies were divided as to whether BCG vaccine was associated with subsequent rates of malignancy, specifically leukemia (protective) and non Hodgkins lymphoma (higher rates). To further evaluate these observations we studied cancer data collected in the 60 year follow up of a controlled trial of BCG in American Indian/ Alaska Native schoolchildren.

MedicalResearch.com Interview with: Phoebe Tran Doctoral Student Department of Chronic Disease Epidemiology Yale School of MedicinePhoebe Tran Doctoral Student Department of Chronic Disease Epidemiology Yale School of Medicine  MedicalResearch.com: What is the background for this study? Response: As the prevalence of diabetes risk factors such as obesity, high blood pressure, high cholesterol, and physical inactivity are considerably higher in US individuals residing in rural areas compared to their urban counterparts, rural residents face increased risk of developing diabetes. Diabetes screening is a useful tool that can be used to identify people with newly developed type 2 diabetes and offer them early treatment. In this study, we examined whether there are differences in diabetes screening levels between rural and urban areas across the US using nationally representative survey data from 2011, 2013, 2015, and 2017.

Response: This study is part of the cohort that consist of the Honolulu Heart Program (HHP) and what later became the Honolulu-Asia Aging study. HHP study cardiovascular research starting in the 1960’s, which is equivalent to the Framingham Study. This study was used to establish the epidemiology parameters for cardiovascular diseases and is one of the longest longitudinal (34 years of follow-up) study on cardiovascular diseases and other diseases that effect the elderly. The participants were all Japanese that fought in WWII which is a sample size of 8,006 participants. In additional, there is multiple studies based on this cohort for the last fifty plus years, ranging from occupational exposure, cancer, neurological diseases, and cardiovascular diseases.

MedicalResearch.com Interview with: [caption id="attachment_51452" align="alignleft" width="200"]Jeremy Brown Jeremy Brown[/caption] Jeremy Brown BA MSc RESEARCH DEGREE STUDENT IN PHARMACOEPIDEMIOLOGY London School of Hygiene & Tropical Medicine MedicalResearch.com: What is the background for this study? Response: Given the way schools typically work, children in the same year as each other can be almost a whole year apart in terms of age. We’ve known for a while that children who are young in their year at school are also more likely to be diagnosed as having hyperactivity disorders and tend to do less well academically than the older children in the year. They also seem to be at increased risk of suicide. This is thankfully an extremely rare occurrence in children, but there is little evidence about whether younger children are more likely to be diagnosed with depression. We used electronic health records for just over a million children in the UK to see if there was any association between how old the children were in their year and whether they got diagnosed with ADHD, intellectual disability and depression.

Response: This is the third project of our data breach trilogy. We first examined which healthcare providers (focusing on hospitals) more likely suffer from a data breach. We documented large hospitals, despite their resources, are more likely to experience a data breach. Some hospitals experienced multiple incidents (https://jamanetwork.altmetric.com/details/18464149). The findings made us wonder what happened? Besides size, what other factors contribute to data breaches? Based on detailed event descriptions, we documented the circumstances under which each data breach occurred (https://jamanetwork.com/journals/jamainternalmedicine/article-abstract/2715158). We found more than half of data breaches could be attributed to healthcare providers’ internal mistakes or negligence (e.g., forgot to encrypt laptop computers, used cc instead of bcc in emailing patients, didn’t revoke former employees’ login credentials after employment terminated) rather than external forces (e.g., hacking). We also found mobile devices (e.g. laptop computers, usb drives) are associated with most data breaches than paper records or network servers. Our results suggest if healthcare providers strengthen their internal control and limit the use of mobile device might be effective ways to reduce data breach risks.

Response: Many people with diabetes are undiagnosed, and those who are diagnosed often are untreated and uncontrolled. Increasing access to health insurance for patients with health care needs was a goal of the Affordable Care Act. We analyzed information from 11 years of the National Health and Nutrition Examination Survey, which gathers data that are nationally representative of the civilian population. The biennial survey includes biomarkers, including HbA1c, a measure of blood-sugar control. Using the NHANES data allowed the researchers to identify those with undiagnosed diabetes.

Response: Our study leveraged radiation dose data from 72 facilities performing CT scans around the United States to learn more about the radiation dose used for lung cancer screening scans, as well as possible institutional predictors that might be associated with higher dose.  Currently, the American College of Radiology has recommendations for how these low-dose lung cancer screening scans should be performed. However, it is unclear how much adherence there currently is to these guidelines. Our findings indicated that there is wide variation in the distribution of radiation doses for low-dose lung cancer screening scans both within- and between facilities in our sample—in some cases this variation led to doses higher than the ACR recommendations.

Response: Every year, the Centers for Medicare and Medicaid Services puts out of notice of proposed changes to the rules governing the Health Insurance Marketplaces created by the Affordable Care Act (e.g., healthcare.gov). The most recent notice for 2020 (issued in 2019) considered eliminating automatic reenrollment for Marketplace enrollees. On the one hand, requiring that enrollees actively select a health plan to stay insured is a good thing because it forces them to consider their options – we know that people make better health plan choices when they consider their choices. On the other hand, creating an administrative barrier to staying insured could cause some people to become uninsured. Since 3.4 million Marketplace enrollees used automatic enrollment in 2019, eliminating it might cause a spike in the uninsured rate.

Friedman, MD Professor of Medicine/Infectious Diseases University of Pennsylvania Philadelphia, PA 19104-6073  MedicalResearch.com: What is the background for this study? Response:  Mice and guinea pigs are the animal models used to evaluate candidate vaccines for preventing genital herpes. My lab has been working on such a vaccine. Our candidate vaccine contains 3 immunogens. One immunogen is a protein on the virus that is required for the virus to enter cells (viruses need to enter cells to replicate). The other two immunogens are proteins on the virus that help the virus escape immune attack. Our intent is to produce antibodies to these 3 proteins by immunization and that the antibodies will bind to the proteins on the virus and block the protein functions. The virus then will not be able to enter cells and will not be able to use its evasion strategies to avoid the immune responses generated by the vaccine. Our vaccine aimed at preventing immune evasion is novel as a component of a genital herpes vaccine.

As a result, the Food and Drug Administration (FDA) warns that youth e-cigarette use is reaching an epidemic proportion in September 2018. Whether e-cigarette use prevalence also increased among young adults (aged 18-24 years), a population with high e-cigarette use rates and vulnerability to nicotine dependence, is unknown.

  • Patients with lung cancer suffer from considerable physical and psychological symptom burden and palliative care is underutilized or delivered too close to death to provide meaningful benefits for these patients. Palliative care is associated with improved quality of life for these patients, but the findings regarding a survival benefit are not clear.
  • Palliative care is distinct from hospice. Palliative care is meant to be delivered along with disease-modifying therapy and focuses on improving quality of life by addressing pain and other problems, including physical, psychosocial and spiritual for patients and their families. Hospice care is focused on reducing suffering, pain and anxiety at the very end of life; typically within a few months of death.
