MedicalResearch.com Interview with: [caption id="attachment_70752" align="alignleft" width="150"]Minji Jung PharmD, PhDPostdoctoral Research Fellow in Epidemiology Department of Urology Stanford University Medical Center Stanford, CA Dr. Minji Jung[/caption] Minji Jung PharmD, PhD Postdoctoral Research Fellow in Epidemiology Department of Urology Stanford University Medical Center Stanford, CA MedicalResearch.com: What is the background for this study? Response: Hypertension is a well-established risk factor for kidney cancer, and previous studies have suggested potential links between antihypertensive medications and kidney cancer risk. However, distinguishing the effects of the medications from those of hypertension itself has been challenging. Our meta-analysis systematically evaluated different classes of antihypertensive drugs while accounting for hypertension.

Alzheimer's - Dementia, Author Interviews, Genetic Research, JAMA, Stanford / 07.11.2023

MedicalResearch.com Interview with: [caption id="attachment_61020" align="alignleft" width="125"]MedicalResearch.com Interview with:Michael E. Belloy, PhD Department of Neurology and Neurological Sciences Stanford University, Stanford, California Dr. Belloy[/caption] Michael E. Belloy, PhD Department of Neurology and Neurological Sciences Stanford University, Stanford, California MedicalResearch.com: What is the background for this study? Response: Apolipoprotein E (APOE)*2 and APOE*4 are, respectively, the strongest protective and risk-increasing, genetic variants for late-onset Alzheimer disease. As such, one’s APOE genotype is highly relevant towards clinical trial design and Alzheimer’s disease research. However, most insights so far are focused on the associations of these APOE genotypes with Alzheimer’s disease risk in non-Hispanic white individuals. One important aspect of our work is that we really increased sample sizes for non-Hispanic Black, Hispanic, and East Asian individuals, so that we now have better understanding of the associations of APOE genotypes with Alzheimer’s disease risk in these groups. In complement, we also did the largest investigation to date on the role of ancestry on the associations of APOE genotypes with Alzheimer’s disease risk. The scale of our study was thus a critical factor in generating novel insights.

  • Lung cancer is the leading cause of cancer death in the United States, killing about 127,000 people annually, but it can be treatable if detected early.
  • Low-dose computed tomography, or CT scan, has been shown to significantly reduce the number of lung cancer deaths. But because the radiation delivered by the scans can be harmful (they use on average about 10 times the radiation of standard X-rays), only those people at relatively high risk for lung cancer should be screened. The two biggest risk factors for lung cancer are exposure to tobacco smoke and age. Current national guidelines that rely on age and smoking exposure to recommend people for lung cancer screening are disproportionally failing minority populations including African Americans, according to a new study led by researchers at Stanford Medicine.
  • In 2021, the national guidelines by the U.S. Preventive Services Task Force (USPSTF) issued revised recommendation guidelines on lung cancer screening, lowering the start age from 55-year to 50-year and the smoking pack-year criterion from 30 to 20, compared to the 2013 USPSTF criteria. In comparison to the 2013 criteria, the new modifications have been shown to lessen racial disparities in screening eligibility between African Americans and Whites. However, potential disparities across other major racial groups in the U.S., such as Latinos, remains poorly examined.
  • Meanwhile, risk prediction model assesses a person’s risk score of developing an illness, such as lung cancer.

What types of cancers were in the study? Response: Genetic testing for cancer risk is increasingly important after a cancer diagnosis, to inform use of targeted therapies, secondary cancer prevention approaches and cascade genetic testing of family members. However, very little is known about how genetic testing is used after a cancer diagnosis at the population level. We leveraged a very large population-based data resource, the Surveillance, Epidemiology and End Results (SEER) cancer registries of the states of California and Georgia, and linked data from these registries to clinical genetic testing results provided by the four major laboratories that provide such testing. We used this linked registry-genetic testing dataset to study adults (age >=20 years) diagnosed with all types of cancer in the states of Georgia and California from 2013-2019.
Alzheimer's - Dementia, Author Interviews, Genetic Research, Race/Ethnic Diversity, Stanford / 21.02.2023

MedicalResearch.com Interview with: [caption id="attachment_60059" align="alignleft" width="125"]Yann Le Guen, Ph.D.Assistant Director, Computational Biology Quantitative Sciences Unit Stanford Medicine Dr. Yann Le Guen[/caption] Yann Le Guen, Ph.D. Assistant Director, Computational Biology Quantitative Sciences Unit Stanford Medicine MedicalResearch.com: What is the background for this study? Response: Apart from aging, the strongest contributing factor for late-onset Alzheimer’s disease is a specific allele of the APOE gene, which has three common alleles E2, E3, and E4. While E3 is the most common and considered as the reference, E2 is associated with decreased Alzheimer’s disease risk and E4 is associated with increased Alzheimer’s disease risk. Notably the prevalence of E4 among Alzheimer’s patient is high with about 60% of these carrying at least one E4 allele, while solely about 30% Americans carry one E4 allele. It’s worth emphasizing that individuals with an E4/E4 genotype have an exponential increased in their risk to develop AD (10 times as likely than the reference E3/E3 genotype), and individuals with an E3/E4 genotype have an intermediate risk. Though, most studies of Alzheimer’s disease genetic have been focused on European ancestry, this is beginning to change thanks to NIH’s efforts to fund more studies in non-European ancestry individuals. Our study built on these recent efforts to assess the Alzheimer disease risk associated with an APOE variant (R145C) present in about ~4% African Americans, but extremely rare in Europeans.

Response: The US Preventive Services Task Force (USPSTF) issued their 2021 recommendation on lung cancer screening lowering the start age from 55 to 50 years and the minimum pack-year criterion from 30 to 20, relative to the 2013 recommendations. Although costs are expected to increase with the expanded screening eligibility, it is unknown if the new guidelines for lung cancer screening are cost-effective.

What are the main findings? Response: To examine adolescent and young adult e-cigarette use during the COVID-19 pandemic. There were 4 main findings:
  • About 2/3 of adolescent and young adult ever-e-cigarette users reported either quitting or cutting back on e-cigarette use since COVID-19 began.
  • Users least likely to quit or cut back e-cigarette use were those showing higher levels of nicotine dependence and those who had used e- cigarettes a large number of times.
  • Adolescent and young adult e-cigarette users found it harder to access e-cigarettes, but unlike studies before COVID-19, the dominant source of purchasing e-cigs was online instead of brick-and-mortar during COVID-19 pandemic.
  • Youth below 21 years were able to purchase e-cigarettes without any age verification, and those whose age was verified were asked to physically show ID or provided an email, which are less effective means to prevent underage youth use.

MedicalResearch.com Interview with: [caption id="attachment_55479" align="alignleft" width="150"]Shuchi Anand M.D. M.S. Director of the Center for Tubulointerstitial Kidney Disease Stanford University Dr. Anand[/caption] Shuchi Anand M.D. M.S. Director of the Center for Tubulointerstitial Kidney Disease Stanford University MedicalResearch.com: What is the background for this study? Response: Seroprevalence (or presence of antibodies in response to SARS CoV-2) is considered by many experts to be the most complete to track the spread of COVID19 in communities. However seroprevalence studies are hard to conduct, because they require going into communities and underdoing random blood draws. Many people—especially racial and ethnic minorities, or people with underlying health conditions, or people with language barriers—may be hard to reach for these types of surveys. Plus outreach into communities is very difficult in light of the COVID19 pandemic. To mitigate this problem we worked with a random sample of 28,503 patients on hemodialysis, the vast majority of whom are covered by Medicare. They get their blood drawn monthly, as part of their routine care. Furthermore even though we used a random sample, we know that patients on dialysis are more likely to be racial and ethnic minorities, and more likely to come from disadvantaged backgrounds.

Leary[/caption] Eileen B. Leary, Ph.D. Student Epidemiology and Clinical Research Stanford University MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by REM sleep? Response: Sleep is a regulated, reversible, and recurring loss of consciousness that is a critical requirement for a happy, healthy life. REM sleep is an important component of sleep defined by rapid eye movements and commonly associated with dreaming. We learned from previous studies that sleep duration is associated with mortality, however little was known about how the different sleep stages relate to timing or cause of death.
Author Interviews, Baylor College of Medicine Houston, COVID -19 Coronavirus, JAMA, Stanford / 07.04.2020

MedicalResearch.com Interview with: [caption id="attachment_53801" align="alignleft" width="200"]MedicalResearch.com Interview with: Melissa Bondy, PhD Chair, Department of Epidemiology and Population Health Stanford University MedicalResearch.com: What is the background for this study? Response: Faculty researchers in Stanford’s Department of Epidemiology & Population Health and collaborators from Baylor College of Medicine and Stanford’s Department of Dermatology developed an online survey aimed at rapidly assessing public concerns about the COVID-19 crisis. This survey, which was posted on 3 social media platforms (Twitter, Facebook, and Nextdoor) on March 14, 2020, collected invaluable data about COVID-19, including symptoms, concerns, and individual actions taken by respondents. Twitter and Facebook posts were sharable to facilitate snowball sampling. The survey was comprised of 21 (multiple-choice, single-choice, numeric, and open-ended) questions, which were designed to collect data concerning respondent demographics and recent cold and flu-like illnesses (if any), as well as information about participants’ concerns and any lifestyle changes that occurred as a result of the COVID-19 crisis. All questions were optional, so response rates were variable. MedicalResearch.com: What are the main findings? Response: 9009 surveys were completed within a 48 hour period, between March 14 and 16. A majority were very or extremely concerns about COVID-19, though concern varied by age. Most respondents reported making lifestyle changes in response to COVID-19. The most common changes were more hand washing, avoiding social gatherings, and stockpiling food and supplies. About half of respondents were self-isolating most of the time before shelter-in-place orders, and leaving the house only to buy food and essentials. Respondents who were not self-isolating all of the time, before the shelter-in-place order, most commonly listed not being able to afford missing work as the reason. The top concerns reported by survey participants were getting sick because of COVID-19 and not being able to get medical care. The most common difficulties reported were obtaining hand sanitizer, food, and childcare. MedicalResearch.com: What should readers take away from your report? Response: This convenience sample survey distributed in mid-March 2020 across 3 social media platforms reflect respondents’ serious concerns about COVID-19. They were preparing for the crisis by washing hands, isolating at home, and practicing social distancing to the best of their abilities. Levels of concern about COVID-19 varied by age groups. Participants expressed the most common difficulties included getting sanitizer or food, arranging childcare, and lost wages or reduced working hours. MedicalResearch.com: What recommendations do you have for future research as a result of this work? Response: Groups who are generally known to be underrepresented in social media, particularly men and older individuals, were underrepresented among survey participants. Few respondents reported concerns about their employment, but the study did not collect information about participants’ socioeconomic status (and was likely high). Our future work will expand geographic representation among survey respondents, with greater focus on longitudinal trends on the health, financial, and social concerns in the United States regarding the COVID-19 pandemic. No disclosures or conflicts of interest. Citation: Nelson LM, Simard JF, Oluyomi A, et al. US Public Concerns About the COVID-19 Pandemic From Results of a Survey Given via Social Media.

MedicalResearch.com Interview with: [caption id="attachment_53694" align="alignleft" width="200"]MedicalResearch.com Interview with: David J. Maron, MD, FACC, FAHA Clinical Professor of Medicine  Chief, Stanford Prevention Research Center Director, Preventive Cardiology Stanford University School of Medicine Dr. Maron[/caption] David J. Maron, MD, FACC, FAHA Clinical Professor of Medicine Chief, Stanford Prevention Research Center Director, Preventive Cardiology Stanford University School of Medicine  MedicalResearch.com: What is the background for this study? Response: Among patients with stable coronary disease and moderate or severe ischemia, whether clinical outcomes are better in those who receive an invasive intervention plus medical therapy than in those who receive medical therapy alone is uncertain. The goals of treating patients with stable coronary disease are to reduce their risk of death and ischemic events and to improve their quality of life. All patients with coronary disease should be treated with guideline-based medical therapy (GBMT) to achieve these objectives. Before the widespread availability of drug-eluting stents, strategy trials that tested the incremental effect of revascularization added to medical therapy did not show a reduction in the incidence of death or myocardial infarction. In one trial, fractional flow reserve–guided percutaneous coronary intervention (PCI) with drug-eluting stents, added to medical therapy, decreased the incidence of urgent revascularization but not the incidence of death from any cause or myocardial infarction at a mean of 7 months, whereas the 5-year follow-up showed marginal evidence of a decrease in the incidence of myocardial infarction.

Author Interviews, Biomarkers, Lung Cancer, Stanford / 09.03.2020

MedicalResearch.com Interview with: [caption id="attachment_53410" align="alignleft" width="149"]Professor Dr. Andreas Keller Stanford University School of Medicine Office Department of Neurology and Neurological Sciences  Chair for Clinical Bioinformatics Saarbrücken, Germany Prof. Keller[/caption] Professor Dr. Andreas Keller Stanford University School of Medicine Office Department of Neurology and Neurological Sciences Chair for Clinical Bioinformatics Saarbrücken, Germany MedicalResearch.com: What is the background for this study? Response: Lung cancer is among the three most common cancers and the leading cause of cancer-related deaths worldwide. The overall low survival rate of patients with lung cancer calls for improved detection tools to enable better treatment options and improved patients’ outcomes. To detect lung tumors, liquid biopsy-based strategies are increasingly explored, that are biomarkers, which are identifiable in body fluids such as human blood. The clinical application of biomarkers is, however, largely hampered by the relatively small numbers of cases that have been analyzed in the majority of the preclinical studies including the studies on lung cancer. 
Author Interviews, Dermatology, Nature, Stanford / 18.10.2019

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. 
Author Interviews, Frailty, Hospital Readmissions, JAMA, Stanford, Surgical Research / 27.05.2019

MedicalResearch.com Interview with: hospital-frailty-surgeryKara Anne Rothenberg.MD Postdoctoral Research Fellow, Vascular Surgery Shipra Arya, MD SM FACS Associate Professor of Surgery Stanford University School of Medicine MedicalResearch.com: What is the background for this study? Response: There is a growing body of literature showing that frailty, a syndrome where patients have increased vulnerability to a stressor (such as surgery), is associated with increased postoperative complications, failure to rescue, and hospital readmissions. The Risk Analysis Index (RAI), is an easy to use frailty measurement tool that better predicts postoperative mortality than age or comorbidities alone. As the rates of outpatient surgeries rise nationwide, we noted that most of the surgical frailty studies focus only on inpatient surgeries. Elective, outpatient surgery is generally considered low risk for complications and unplanned readmissions, however we hypothesized that for frail patients, it might not be.

Wall, PhDAssociate ProfessorDepartments of Pediatrics, Psychiatry (by courtesy) and Biomedical Data ScienceStanford University Dr. Wall[/caption] Dennis P. Wall, PhD Associate Professor Departments of Pediatrics, Psychiatry (by courtesy) and Biomedical Data Science Stanford University  MedicalResearch.com: What did we already know about the potential for apps and wearables to help kids with autism improve their social skills, and how do the current study findings add to our understanding? What’s new/surprising here and why does it matter for children and families?  Response: We have clinically tested apps/AI for diagnosis (e.g.  https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1002705) in a number of studies. This RCT is a third phase of a phased approach to establish feasibility and engagement through in-lab and at-home codesign with families with children with autism. This stepwise process is quite important to bring a wearable form of therapy running AI into the homes in a way that is clinically effective. What’s new here, aside from being a first in the field, is the rigorous statistical approach we take with an intent-to-treat style of analysis. This approach ensures that the effect of the changes are adjusted to ensure that any significance observed is due to the treatment.  Thus, with this, it is surprising and encouraging to see an effect on the VABS socialization sub-scale. This supports the hypothesis that the intervention has a true treatment effect and increases the social acuity of the child. With it being a home format for intervention that can operate with or without a clinical practitioner, it increases options and can help bridge gaps in access to care, such as when on waiting lists or if the care process is inconsistent.

MedicalResearch.com Interview with: Alan Nelson, MPAS, PhD Division of Primary Care and Population Health, Department of Medicine Stanford University School of Medicine Stanford, California  MedicalResearch.com: What is the background for this study?   Response: The past research literature has provided relatively little information on the appropriate level of concern regarding non-steroidal anti-inflammatory drugs (NSAIDs) and kidney disease risk among younger, apparently healthy patients. Clinicians are generally most concerned about the effects of these medications on the kidneys among patients with existing renal impairment and persons at risk for it, especially older patients. Given that NSAID use appears to be high and rising in the US, we were interested in developing evidence on this topic in a population of working-age adults.

Response: n 2017, the results from the much-awaited Canakinumab Anti-inflammatory Thrombosis Outcome Study (CANTOS) trial were published, confirming the inflammatory hypothesis, i.e. that targeting inflammation can reduce cardiovascular disease. The trial tested the monoclonal antibody canakinumab in a population of post-myocardial infarction patients with elevated inflammation markers (hs-CRP). Canakinumab is currently used for rare diseases and carries an orphan drug price: the 150mg dose used in CANTOS costs approximately $73,000 per year. Due to the high prevalence of cardiovascular disease, millions of patients could potentially be eligible for treatment with this high-priced anti-inflammatory drug. Therefore, we wanted to investigate the cost-effectiveness for canakinumab for secondary prevention of cardiovascular disease, using the reported results from CANTOS.

MedicalResearch.com Interview with: [caption id="attachment_46704" align="alignleft" width="200"]Fatima Rodriguez, MD, MPH, FACC Assistant Professor Cardiovascular Medicine Stanford University School of Medicine Dr. Rodriguez[/caption] Fatima Rodriguez, MD, MPH, FACC Assistant Professor Cardiovascular Medicine Stanford University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The “Hispanic Paradox” is an idea based on some epidemiological observations that Hispanics have lower disease prevalence and mortality (across a wide spectrum of disease states), despite adverse risk profiles and lower socioeconomic status than their non-Hispanic white counterparts. Our study is unique in that it includes a Hispanic population with overall high educational attainment followed longitudinally. In contrast to prior work in this area, we found no evidence in support of the Hispanic paradox for estimated atherosclerotic cardiovascular disease risk, atherosclerotic disease (as measured by CAC), or overall mortality.

MedicalResearch.com Interview with: [caption id="attachment_45897" align="alignleft" width="150"]Katie Hastings MPH Stanford Medicine  Kate Hastings[/caption] Katie Hastings MPH Stanford University School of Medicine Stanford, California MedicalResearch.com: What is the background for this study? What are the main findings? Response: Heart disease has been the leading cause of death since the early 1900s, but recent data has suggested cancer will surpass heart disease in the upcoming decades. To date, this is the first study to examine the transition from heart disease to cancer mortality as the leading cause of death by U.S. county and sociodemographic characteristics using national mortality records from 2003 to 2015. Our main findings are:
  • Epidemiologic transition is occurring earlier in high compared to low income U.S. counties, and occurs earlier for Asian Americans, Hispanics, and NHWs compared to blacks and American Indians/Alaska Natives.
  • Data may suggest that this shift arises from larger reductions in heart disease than cancer mortality over the study period, particularly in the highest income counties.
  • Continued disparities in heart disease and cancer mortality between blacks and other racial/ethnic groups, even in the highest income quintiles. While blacks continue to have the highest overall mortality than any other group, we do show this population experienced the greatest overall improvements in mortality (i.e. mortality rate reductions over time) for all-cause, heart disease, and cancer compared to all other racial/ethnic groups (except for heart disease in Hispanics).

MedicalResearch.com Interview with: "Mycobacterium tuberculosis Bacteria, the Cause of TB" by NIAID is licensed under CC BY 2.0Purvesh Khatri, Ph.D. Associate Professor Stanford Institute for Immunity, Transplantation and Infection (ITI) Stanford Center for Biomedical Informatics Research (BMIR) Department of Medicine Stanford University Stanford, CA 94305 MedicalResearch.com: What is the background for this study? What are the main findings? Response: We have previously described a 3-gene signature for distinguishing patients with active tuberculosis (ATB) from those with other diseases, latent mycobacterium tuberculosis (LTB) infection, and healthy controls (Sweeney et al. Lancet Respir Med 2016). The current study in JAMA Network Open is a follow up study to validate the 3-gene signature in 3 additional independent cohorts that were prospectively collected. Using these 3 cohorts we have now showed that the 3-gene signature (1) can identify patients with LTB that will progress to ATB about 6 months prior to diagnosis of active tuberculosis. (2) can identify patients with ATB in active screening, and (3) can identify patients with ATB at diagnosis that have higher likelihood of persistent lung inflammation due to subclinical ATB at the end of treatment.

MedicalResearch.com Interview with: Dr. Janey Pratt, MD Clinical Associate Professor, Surgery Stanford UniversityDr. Janey Pratt, MD Clinical Associate Professor, Surgery Stanford University MedicalResearch.com: What is the background for this study? What are the main findings? Response: In 2013 obesity became recognized as a disease.  The rate of pediatric obesity continues to rise.  Severe pediatric obesity is rising at a even faster rate than obesity in pediatrics.  Despite this Metabolic and Bariatric Surgery (MBS) remains underutilized in the treatment of severe pediatric obesity.  There is a significant amount of adult data and now pediatric data about effective treatments for severe obesity.  These support the use of MBS as a primary treatment for severe obesity in children.

Would you briefly explain what is meant by an atypical mycobacterial infection?  Response: Our interest in undertaking this study stems from three important clinical observations and issues. First, the use of inhaled steroid medications for a broad variety of respiratory complaints and diseases is increasing, including in clinical circumstances where there isn’t much strong supportive evidence for benefit to patients from using inhaled steroids. The second observation is that steroids can and do alter immune system responses, and can increase the risk for some infections. There are already data from studying patients on inhaled steroids where the incidence of bacterial respiratory infections has increased, supporting the concerns for infection risk from inhaled steroids. And the third issue is that steroids can more specifically alter immune system function that helps combat mycobacterial infections, and this means that the risk for, and incidence of mycobacterial infections could be increased in patients treated with inhaled steroids. The best known mycobacterial infection is of course tuberculosis, but there are other mycobacteria, called nontuberculous mycobacterial (or atypical mycobacterial) that are broadly found in the environment, and some of those nontuberculous mycobacteria (NTM) can cause lung infections. So our hypothesis was that the use of inhaled steroids might be associated with an increased frequency of NTM infections, and we designed the study to explore that hypothesis.
