[caption id="attachment_41598" align="alignleft" width="200"]Dr-Allison W. Kurian Dr. Kurian[/caption] MedicalResearch.com Interview with: Allison W. Kurian, M.D., M.Sc. Associate Professor of Medicine (Oncology) and of Health Research and Policy Director, Women’s Clinical Cancer Genetics Program Stanford University School of Medicine Stanford, CA 94305-5405  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Changes in genetic sequencing technology and regulation have allowed much cheaper testing of many more genes in recent years. We investigated how these changes have affected hereditary cancer risk evaluation in women newly diagnosed with breast cancer. The main findings are that more comprehensive multiple-gene sequencing tests have rapidly replaced more limited tests of two genes (BRCA1 and BRCA2) only. This has helped patients by doubling the chance of finding an important gene mutation that can change their treatment options. However, there are important gaps in how this new, more comprehensive sequencing is used: more testing delays and more uncertain results, particularly among racial/ethnic minority women. 
Author Interviews, JAMA, Kidney Disease / 11.05.2018

MedicalResearch.com Interview with: “Glass of Water” by Greg Riegler is licensed under CC BY 2.0Dr. William Clark Lawson Health Research Institute  MedicalResearch.com: What is the background for this study? What are the main findings? Response:  This study is about the use of increased water intake in people with chronic kidney disease (CKD). Although there are a large number of benefits claimed most are not substantiated by evidence. However there is a growing body of evidence (animal and human observational studies) that increased hydration with the suppression of antidiuretic hormone preserves kidney function in CKD. This led to our current randomised clinical trial of 631 patients with stage 3 CKD and proteinuria to determine if drinking an extra 4-6 glasses of water per day for 1 year would slow their progressive loss of kidney  function as measured by eGFR. The main findings were that those coached to increase their water intake versus those coached to sustain their normal fluid intake suffered no ill effects from the intervention and on average were able to sustain an average increase of approximately 3 glasses of water per day. At the end of 1 year the increased hydration group had suppressed their antidiuretic hormone levels (copeptin) significantly but did not demonstrate a greater preservation in their eGFR.

What are the main findings? Response: Prostate cancer is one of the most common cancers to affect men. However, the decision about whether to be screened is complex and personal. The U.S. Preventive Services Task Force reviewed the latest research on the benefits and harms of screening for prostate cancer using PSA-based testing, as well as evidence on treatment. We found that men who are 55 to 69 years old should discuss the benefits and harms of screening with their doctor, so they can make the best choice for themselves based on their values and individual circumstances. Men age 70 and older should not be screened, as the benefits of screening diminish as men age and the harms are greater.

Response: Schizophrenia and other psychotic disorders are still all to often chronic and recurring mental health conditions that not uncommonly take a course during which individuals have varying degrees of significantly impaired personal, social and educational/vocational functioning. Prior individual studies examining early specialty intervention services, which integrate multiple different and complementary treatment components, had shown that this treatment approach can yield superior outcomes for people with early-phase schizophrenia and other psychotic disorders compared to usual care given to all people with psychotic disorders. However, we were lacking a broad overview of the type and results of treatment programs that had been conducted across different countries, continents and mental health service delivery systems. Moreover, we did not yet have a synthesis across all important outcomes that had been examined across these individual studies. This first comprehensive meta-analysis on this topic provides previously missing information on the different early intervention programs and their components as well as on all relevant outcomes for people who did or did not receiving early integrated care, also recently called ‘coordinated specialty care.’

What are the main findings?
  • Previous studies have found a link between moderate to severe head injuries and increased dementia risk.
  • The association between mild head injuries and dementia – especially mild head injury that doesn’t result in loss of consciousness – is less well established
  • We examined the association between mild head injuries with and without loss of consciousness and dementia diagnoses in nearly 360,000 Veterans receiving care in the VA health care system.
  • We found that Veterans with a head injury diagnoses were two to four times more likely to be diagnosed with dementia than those without head injury diagnoses.
  • The risk of dementia diagnosis was doubled in Veterans who experienced head injury without loss of consciousness compared to those with no head injury.

Carrington Reid, MD PhD Associate Professor of Medicine Irving Sherwood Wright Associate Professor in Geriatrics Joachim Silbermann Family Clinical Scholar Geriatric Palliative Care Joan and Sanford I. Weill Department of Medicine Weill Cornell Medical College MedicalResearch.com: What is the background for this study?   Response: Major guidelines (American College of Physicians, Centers for Disease Control, Veterans Administration) on the management of chronic pain strongly encourage clinicians to use nonpharmacologic approaches to include psychological therapies when managing pain. While many studies have evaluated psychological therapies such as cognitive behavioral theraphy (CBT) in nonelderly populations with chronic pain, far fewer have evaluated these treatments in studies of older adults. We identified 22 randomized controlled trials that evaluated a psychological therapy for chronic pain in older adults and examined the impact of these treatments on salient outcomes to include ability to reduce pain and pain-related disability, improve patients' self efficacy to manage pain, and improve their physical health and function and their psychological health (by reducing rates of anxiety and depression).

Kelsey, MD, MOH Professor of Epidemiology and Pathology and Laboratory Medicine Fellow, Collegium Ramazzini Providence, R.I. 02912 MedicalResearch.com: What is the background for this study? What are the main findings? Response: ​There is a large literature suggesting that the ratio of neutrophils to lymphocytes (the neutrophil to lymphocyte ratio or NLR) in the peripheral blood at the time of diagnosis is robustly predictive ​of outcome in acute cardiovascular disease. We were curious to know if the peripheral blood profile and this ratio was a feature of the disease process, since, to our knowledge, this had not been investigated in a prospective study.  Hence, we used the resources of 2 prospective studies to assess this question, the Jackson Heart Study and the Normative Aging Study.  In both cases, the NLR predicted all cause mortality and, in the Jackson Heart Study, where we had well adjudicated outcomes, the NLR predicted various specific cardiovascular outcomes as well. Interestingly, the outcome was also modified by a well known genetic polymorphism of African origin that results in a relative neutropenia.

Response: Circulating tumor cells are cancer cells that are shed from the primary tumor into the peripheral blood stream and are hypothesized to be one of the first steps in the initiation of metastatic progression. Prospective studies have demonstrated that approximately 15-25% of patients with early-stage breast cancer can be found to have at least one circulating tumor cell in a small sample of their blood. Currently, all patients with early-stage invasive breast cancer who undergo breast conserving surgery receive adjuvant radiation therapy. In these analyses, we wanted to determine whether presence of circulating tumor cells may be predictive of benefit of radiation therapy following surgery.
Author Interviews, Breast Cancer, Brigham & Women's - Harvard, JAMA, Mammograms / 03.05.2018

MedicalResearch.com Interview with: [caption id="attachment_41460" align="alignleft" width="200"]Anne Marie McCarthy, PhD Department of Medicine Massachusetts General Hospital and Harvard Medical School Boston Dr. McCarthy[/caption] Anne Marie McCarthy, PhD Department of Medicine Massachusetts General Hospital and Harvard Medical School Boston MedicalResearch.com: What is the background for this study? What are the main findings? Response: Mammography is effective in reducing breast cancer mortality. However, it is not perfect, and approximately 15% of breast cancers are diagnosed despite a negative mammogram before the next recommended screening. MedicalResearch.com: What should clinicians and patients take away from your report? Response: Using data from the NCI funded PROSPR (Population-Based Research Optimizing Screening through Personalized Regimens) Consortium, we determined the rates of cancer diagnosis within one year following a negative or positive screening mammogram. The rate of cancer diagnosis within one year of a negative mammogram was small (5.9 per 10,000 screenings), but those cancers were more likely to have poor prognosis than cancers diagnosed after a positive mammogram (43.8% vs. 26.9%). As expected, women with dense breasts were more likely to have cancer diagnosed within 1 year of a negative mammogram. However, breast density was not a good predictor of poor prognosis among women diagnosed with cancer after a negative mammogram. Younger women were more likely to be diagnosed with poor prognosis breast cancer after a negative screening mammogram.

MedicalResearch.com Interview with: Dr-Hillary-J-Mull Hillary J. Mull, PhD, MPP Center for Healthcare Organization and Implementation Research Veterans Affairs (VA) Boston Healthcare System Department of Surgery, Boston University School of Medicine Boston, Massachusetts MedicalResearch.com: What is the background for this study? What are the main findings? Response: Little is known about outpatient procedures that can be considered invasive but are not conducted in a surgical operating room. These procedures are largely neglected by quality or patient safety surveillance programs, yet they are increasingly performed as technology improves and the U.S. population gets older. We assessed the rate of invasive procedures across five specialties, urology, podiatry, cardiology, interventional radiology and gastroenterology in the Veterans Health Administration between fiscal years 2012 and 2015. Our analysis included examining the rates of post procedure emergency department visits and hospitalizations within 14 days and the key patient, procedure or facility characteristics associated with these outcomes. We found varying rates of post procedure ED visits and hospitalizations across the specialties with podiatry accounting for a high volume of invasive outpatient care but the lowest rate of postoperative utilization (1.8%); in contrast, few of the procedures were in interventional radiology, but the postoperative utilization rate was the highest at 4.7%. In a series of logistic regression models predicting post procedure healthcare utilization for each specialty, we observed significantly higher odds of post procedural outcomes for African American patients compared to white patients.

Katz Professor and Chair Brookdale Department of Geriatrics and Palliative Medicine Icahn School of Medicine at Mount Sinai New York, NY 10029 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Palliative care is team based care that is focused on improving quality of life and reducing suffering for persons with serious illness and their families.  It can be provided at any age and in concert with all other appropriate medical treatments.  Palliative care has been shown to improve patient quality of life, patient and family satisfaction, and in diseases like cancer and heart failure, improve survival.  A number of individual studies have shown that palliative care can reduce costs by providing the right care to the right people at the right time. This study pooled data from six existing studies to quantify the magnitude of savings that high quality palliative care provides.

This study was conducted against the backdrop of a significantly higher risk for stroke among African Americans compared to non-Hispanic Whites, despite adjusting for traditional risk factors. Also, sickle cell disease is a well-known genetic risk factor for stroke and recent studies show that sickle cell trait is a risk factor for chronic kidney disease, venous thromboembolism and pulmonary embolism, all of which are potential risk factors for stroke.

What are the main findings?  Response: Evidence from longitudinal studies suggests that self-regulation skills can be a powerful predictor of positive health, educational, financial and social outcomes. Hence, self-regulation has received interest as an intervention target and a number of interventions have been evaluated in children and adolescents. Our study summarised the evidence from 50 rigorously evaluated self-regulation interventions in children and adolescents including 23098 participants. We found that while most interventions were successful in improving self-regulation (66%), some of them did not produce a noticeable change (34%).Curriculum based approach was most commonly used to deliver interventions, and this involved training teachers, who implemented these interventions.

Ferris[/caption] Laura K. Ferris MD, PhD Associate Professor, University of Pittsburgh Clinical and Translational Science Institute Director of Clinical Trials, UPMC Department of Dermatology University of Pittsburgh MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Dermatology is one of the greatest utilizers of physician extenders, including physician assistants (PAs) in medicine. The scope of practice of PAs has also expanded over time from a role in assisting the dermatologist to taking a more independent role and many PAs now do skin cancer screening examinations and make independent decisions about which lesions are suspicious for skin cancer and need to be biopsied. Our main findings were that, overall, in comparison to board-certified dermatologists, PAs were more likely to perform biopsies of benign lesions. For every melanoma that they found, PAs biopsied 39 benign lesions whereas dermatologists biopsied 25. In addition, PAs were less likely than dermatologists to diagnose melanoma in situ, the earliest and most curable, but also hardest to identify and diagnose, form of melanoma. However, PAs had a similar rate of diagnosing the more clinically-obvious forms of skin cancer, including invasive melanoma, basal cell carcinoma, and squamous cell carcinoma.

Response: Compared to previous placebo-controlled statin trials, the FOURIER trial where all patients were on high or moderate intensity statin, had no reduction in cardiovascular or total mortality and the reduction in cardiovascular events was less than expected.  However, other PCSK9 inhibitor trials performed in populations with higher baseline low density lipoprotein cholesterol (LDL-C) had cardiovascular risk reductions similar to that in the statin trails.
Author Interviews, Blood Pressure - Hypertension, JAMA, Primary Care / 16.04.2018

MedicalResearch.com Interview with: “Doctors” by Tele Jane is licensed under CC BY 2.0Doug Einstadter, MD, MPH Center for Health Care Research and Policy MetroHealth System and Case Western Reserve University  MedicalResearch.com: What is the background for this study?   Response: Despite the recognized importance of blood pressure (BP) control for those with hypertension, based on national surveys only 54% of patients with hypertension seen in primary care have their BP controlled to less than 140/90 mm Hg. Blood pressure measurement error is a major cause of poor BP control. Reducing measurement error has the potential to avoid overtreatment, including side effects from medications which would be intensified or started due to a falsely elevated blood pressure. One way to reduce measurement error is to repeat the BP measurement during an office visit. The American Heart Association recommends repeating a blood pressure at the same clinic visit with at least 1 minute separating BP readings, but due to time constraints or lack of evidence for the value of repeat measurement, busy primary care practices often measure BP only once. Repeating the BP at the same office visit when the initial blood pressure measurement is high has the potential to improve clinical decision-making regarding BP treatment. Several studies have described the effect of a repeat BP measurement in the inpatient setting, but there are little data available to characterize the effect of repeating blood pressure measurement in an outpatient primary care setting.

MedicalResearch.com Interview with: Lindor Qunaj BSc MD'19 Medical student, Warren Alpert Medical School of Brown University Brown Center for Biomedical Informatics Providence, Rhode Island MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study was motivated by growing concerns that incomplete or delayed release of clinical trial data may put patients at risk of harm or suboptimal treatment and slow the pace of biomedical innovation. Especially in a field as rapidly evolving as oncology, complete and timely dissemination of clinical trial results is critical to the advancement of both patient care and scientific discovery. In an analysis of press releases from eight large pharmaceutical companies, we found that the median delay from presumed availability of Phase 3 trial data to peer-reviewed publication or public posting of results was 300 days. Studies reporting positive findings were published more rapidly than those with negative results.

Philip Kistler Stroke Research Center Division of Neurocritical Care and Emergency Neurology, Department of Neurology MGH Harvard Medical School, Boston Department of Emergency Medicine Massachusetts General Hospital for the Antihypertensive Treatment of Acute Cerebral Hemorrhage 2 (ATACH-2) and the Neurological Emergencies Treatment Trials (NETT) Network Investigators   MedicalResearch.com: What is the background for this study? What are the main findings?  Response: It’s hard to know how aggressively to lower blood pressure in acute intracerebral hemorrhage (ICH).  Randomized controlled trials have been conflicting. We thought that we could use the presence of severe small vessel disease (SVD) - manifested by microbleeds seen on brain magnetic resonance imaging (MRI) – to guide treatment decisions.  On the one hand, those with severe SVD may be most vulnerable to continued bleeding, and specifically need more intensive blood pressure lowering.  On the other hand, if they have impaired regulation of cerebral blood flow, they might be harmed by rapid drops in blood pressure, and maybe we have to be more careful with them. To answer this, we performed a subgroup analysis of the multi-centre ATACH-2 clinical trial of intensive blood pressure lowering. This was the first study to assess the effect of randomized acute stroke treatment on patients with more severe SVD, manifested by microbleeds.  We found that no matter what your small vessel disease burden on MRI, you’ll respond the same to early blood pressure management.

Response: Although there have been a few studies that have looked at the relation between being bullied and disordered eating, most studies have looked at it from the perspective of does being bullied lead to disordered eating and does depressive symptoms mediate (i.e., explain) the link. We wanted to look more closely at how bullying, disordered eating, and depression were related over time among teenagers by examining all possible pathways. Another novel aspect of our study was the focus on disordered eating behaviour only (e.g., vomiting, using diet pills, binge eating). Most previous work has examined behaviour and thoughts together, but because disordered eating thoughts are so common (termed normative discontent; e.g., fear of fat, dissatisfaction with body shape or size), particularly among girls and women, we wanted to focus on behaviour, which is more problematic in terms of physical and psychiatric health.

What’s new/surprising here and why does it matter for mothers and babies? Response: Prior studies have shown mixed results in terms of the associations between maternal SRI use during pregnancy and offspring’s brain and cognitive development. Neurobiological studies with animal models suggest that SSRI use perturbs serotonin signaling and that this has important effects on cognitive development (a study conducted an author of this paper, Jay Gingrich, MD, PhD: Ansorge et al., 2004, Science). The human literature has been more mixed in terms of the associations of prenatal exposure to SSRI with brain and cognitive development. In our study, we used neonatal brain imaging because this is a direct, non-invasive method to test associations between SSRI use and brain development at an early developmental stage, limiting the effects of the post-natal environment. In our study, we had two different control groups, that is, a non-depressed SSRI-free group (healthy controls), and depressed but SSRI-free (SSRI controls) group. Also, in our study we used rigorous imaging analytics that significantly improve the quantitative nature of MR-derived signals from the brain structure using two of the nation’s fastest supercomputers (Argonne National Laboratory and Texas Advanced Computing Center) and allows robust reconstruction of brain’s grey and white matter structure in the infants’ brains. We report a significant association of prenatal exposure to SSRI with a volume increases within many brain areas, including the amygdala and insula cortex, and an increase in white matter connection strength between the amygdala and insular cortex. We were surprised by the magnitude of the effects (or the statistical effect size), compared with other brain imaging studies in psychiatry with children or adults’ brains. Importantly, it should be noted that our estimates of brain structure are still experimental and for research-purpose only. This means that our data need to be replicated and rigorously tested against confounders in order to make a firm conclusion. While our study suggests a “potential” association between prenatal exposure to SSRI and a change in fetal or infant brain development, we still need more research.  tracts_in_the_brain

What are the main findings? Response: It is already known that people with epilepsy are at a higher risk of death than those without epilepsy but we didn’t know much about the risks of different types of death. Unnatural death (mainly accident and suicide) accounts for a very small number of all deaths but, compared to people without epilepsy, people with epilepsy are three times more likely to die by accident and twice as likely to die by suicide. Within these broad categories, persons with epilepsy are five times more likely to die specifically by accidental poisoning with medication, and three times more likely to die by intentionally poisoning themselves with medication. Opioid painkillers and medicines for mental illness were the ones most commonly used in poisoning deaths among people with epilepsy and those without epilepsy. Antiepileptic drugs were taken relatively infrequently-they were involved in about 10% of poisoning deaths in people with epilepsy.

Sheps Center for Health Services Research The University of North Carolina at Chapel Hill MedicalResearch.com: What is the background for this study? What are the main findings? Response: Financial relationships between physicians and the pharmaceutical industry are very common. However, we are just beginning to figure out whether these relationships may lead to potentially concerning changes in physician behavior - whether physicians tend to prescribe more of the drugs made by a company that has given them money. We decided to ask whether oncologists who receive money from drugmakers are more likely to use the cancer drugs made by companies that have given them money in the past. In studying two specific groups of cancer drugs, one for kidney cancer and one for chronic myeloid leukemia (CML), we found that oncologists who had received payments such as meals, consulting fees, travel & lodging expenses from the manufacturer of one of these drugs tended to use that drug more. When looking at oncologists who received payments for research, we found increased prescribing among the kidney cancer drugs but not the CML drugs.

Lugo-Candelas, PhD Postdoctoral Research Fellow Columbia University Medical Center/ New York State Psychiatric Institute Dr. Lugo-Candelas[/caption] Claudia I. Lugo-Candelas, PhD Postdoctoral Research Fellow Columbia University Medical Center/ New York State Psychiatric Institute MedicalResearch.com: What is the background for this study? What are the main findings? Response: We have seen, in the last decade, an increase in the amount of mothers being prescribed SSRIs during pregnancy. While we know that untreated prenatal maternal depression has adverse consequences for both the mother and child, it’s not really clear what, if any, are the consequences of prenatal SSRI exposure on infant’s brain development. There have been some studies finding increased depression and anxiety in children prenatally exposed to SSRIs, but not all studies find these associations. We thus looked at 2-4 week old infants’ brains, using neuroimaging.  We found increased gray matter volume within the amygdala and insula, and increased white matter connectivity between these two structures in infants prenatally exposed to SSRIs. Of note, the statistical significance and the size of the effects we detected are quite large, even greater than the brain changes that we usually observe in our studies of children and adults with psychiatric disorders. Further, because these structures are involved in emotion processing, and alterations in volume and connectivity are sometimes seen in clinical populations, or in people at risk for anxiety, it important to learn more about what these volume and connectivity differences could mean for these infants.

What are the main findings? Response: Nearly half of all patients with amyotrophic lateral sclerosis (ALS), a fatal neuromuscular disorder, develop cognitive problems that affect memory and thinking. Why a disease that primarily affects movement also disrupts thinking has been unclear. Our findings suggest that genetic connections between the two disorders may explain why they share some of the same features and suggest that some drugs developed to treat ALS also may work against frontotemporal dementia and vice versa. We used a statistical method in almost 125,000 individuals with ALS, frontotemporal dementia (FTD), progressive supranuclear palsy, corticobasal degeneration, Alzheimer’s disease and Parkinson’s disease to determine whether there are common genetic variants that increase risk for multiple neurodegenerative diseases. We found that common variants near the MAPT gene, which makes the tau protein, increases risk for ALS. MAPT has previously had been associated with diseases including frontotemporal dementia and Alzheimer’s disease. But the gene hadn’t been linked to ALS. We also identified variations in a second gene, BNIP1, which normally plays an important role in protecting against cell death, increased the risk of both ALS and frontotemporal dementia. ImportantlyBNIP1 mRNA levels were altered in people who had ALS and in patients with frontotemporal dementia, suggesting the BNIP1 may be a potential therapeutic target for both disorders.

MedicalResearch.com Interview with: [caption id="attachment_40941" align="alignleft" width="200"]Dr. Aideen Maguire Centre of Excellence for Public Health Queen's University Belfast Institute of Clinical Sciences B Royal Hospitals Site, Belfast Dr Aideen Maguire[/caption] Dr. Aideen Maguire Centre of Excellence for Public Health Queen's University Belfast Institute of Clinical Sciences B Royal Hospitals Site, Belfast MedicalResearch.com: What is the background for this study?   Response: Consanguineous Marriage is the marriage between second or first cousins. Although not common practice in the Western world approximately 1 in 10 children worldwide are born to consanguineous parents. It is legal in all countries worldwide except the United States of America, North Korea and China. Cousin-marriage is associated with an increased risk of autosomal recessive genetic disorders in offspring but the association between cousin-marriage and the mental health of offspring has not been extensively studied. MedicalResearch.com: What are the main findings? Response: Children of consanguineous parents are over 3 times more likley to be in receipt of medications for common mood disorders (antidepressant and/or anxioltyic medication) compared to children of non-related parents and over twice as likley to be in receipt of antipsychotic medication compared to children of non-related parents.

MedicalResearch.com Interview with: Dr. Alvin Chandra  MD first author  and Dr. Scott David Solomon M.D. Director, Noninvasive Cardiology Professor, Harvard Medical School Cardiovascular Medicine Brigham and Women’s Hospital Boston, Massachusetts MedicalResearch.com: What is the background for this study? What are the main findings? Response: In general, the quality of life of heart failure with reduced ejection fraction patients is quite impaired, and  similar to that of patients on dialysis. PARADIGM-HF was the largest trial of heart failure patients and showed that sacubitril/valsartan was superior to the gold-standard enalapril in reducing cardiovascular death, heart failure hospitalization and all-cause mortality. In addition, patients on sacubitril/valsartan, when compared to enalapril, showed significant improvement in overall quality of life. In this study we looked in more detail at the individual components of “quality of life” and found that in virtually all domains and activities, patients who were randomized to sacubitril/valsartan reported improvement in their limitations  compared to those who were randomized to enalapril. These activities included jogging, doing hobbies, and household chores, with the largest improvement seen in  sexual activities limitations.

What are the main findings? Response: When the human genome was sequenced in 2003, there were somewhat unrestrained expectations of unraveling all etiologic mysteries and discovering breakthrough treatments. Needless to say, that did not happen, in part because individual genetic variants can only account for a small fraction of trait variability. Since then, epigenetics-- the study of mitotically heritable changes in gene expression-- has emerged as another promising avenue for understanding disease risk. The best studied epigenetic process in humans is DNA methylation, and earlier studies (including some from our group) have shown interesting associations between changes in methylation in specific genomic regions and cardiovascular disease traits, e.g. plasma cholesterol levels. In this project, we have combined DNA methylation data on thousands of individuals from multiple international cohorts and interrogated epigenetic contributions to circulating tumor necrosis factor alpha (TNFa), a marker of systemic inflammation. We identified and replicated several epigenomic markers of TNFa, linked them to variation in gene expression, and showed that these methylation changes (which were located in interferon pathway genes) were predictive of coronary heart disease later in life. Interestingly, the variants we discovered were not sequence-dependent (in other words, they were not associated with any genetic mutations), highlighting the role of the environment.
