MedicalResearch.com Interview with: Hsin-Jen Chen, PhD MS Assistant Professor Institute of Public Health National Yang-Ming University Taipei City MedicalResearch.com: What is the background for this study? Response: The number of eating occasions may affect health. Laboratory experiments have been showing that splitting daily food consumption into more eating occasions could improve metabolic profiles, such as healthier blood glucose and lipids levels. However, such kinds of experiments usually design a highly controlled diet for the participants in the lab. It is questionable whether such metabolic benefits remain in our daily life (namely, no controlled diets) where we can eat at anytime when we want to eat. (more…)
Author Interviews, Infections / 12.07.2016

MedicalResearch.com Interview with: Jenny A. K. Ekberg Eskitis Institute for Drug Discovery Faculty of Health Sciences and Medicine, Bond University Institute for Health and Biomedical Innovation, Queensland University of Technology, School of Medical Science, Griffith University Queensland, Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: Melioidosis is a tropical bacterial infection that causes around 90,000 deaths world-wide each year. It is caused by the bacteria Burkholderia pseudomallei which can cause pneumonia and a serious flu-like illness which can cause death, however if the brain is infected, which happens in particular with the Australian variant of the disease, the mortality is particularly high (~25 %). The route by which the bacteria invade and progress through the central nervous system is to date largely unknown. We have now shown in an animal model that the bacteria can penetrate the trigeminal nerve within the nasal cavity and then rapidly invade the brainstem and spinal cord only 24 hours after intranasal inoculation. By migrating along the trigeminal nerve, the bacteria bypasses the blood-brain barrier.This study constitutes the first characterization of the path by which B. pseudomallei bacteria migrate all the way from the nasal cavity into the spinal cord.

What are the main findings? Response: Alcohol use disorder is a big problem for our society and only a limited number of medicine is available. We hope to find more treatment in animal models of alcoholism. A group of neurons containing dopamine D2 receptors in the brain prevent us from drinking alcohol heavily. (more…)
Author Interviews, Cancer Research, Cost of Health Care, Health Care Systems, JAMA / 11.07.2016

MedicalResearch.com Interview with: Laura B. Vater, MPH MD Candidate 2017 Indiana University School of Medicine MedicalResearch.com: What is the background for this study? Response: In the United States, cancer center advertisements are common. Previous research has shown that these ads use emotion-based techniques to influence viewers and omit information about benefits, risks, and costs of cancer treatment. There is a concern that cancer center advertising may increase demand for unnecessary tests and treatments, increase healthcare costs, and provide unrealistic expectations about the benefits of cancer treatment. In this study, we examined cancer center advertising spending from 2005 to 2014, with particular attention to trends within media (television networks, magazines, newspapers, radio stations, billboards, and the Internet) and by target audience (national versus local).

Author Interviews, Heart Disease, Lipids / 11.07.2016

MedicalResearch.com Interview with: Joost Besseling, PhD-student Academic Medical Center Dept. of Vascular Medicine Amsterdam MedicalResearch.com: What is the background for this study?  Response: It was unkown to what extent statin therapy reduces the risk for coronary artery disease and mortality in patients with heterozygous familial hypercholesterolemia (FH). One previous study found that the relative risk reduction was 76%, but the study population in this study consisted of with a very severe FH phenotype. This result is therefore an overestimation of the risk reduction in the general heterozygous familial hypercholesterolemia population. (more…)
Alzheimer's - Dementia, Author Interviews, Brain Injury, JAMA, Parkinson's / 11.07.2016

MedicalResearch.com Interview with: Paul K. Crane, MD MPH Professor Department of Medicine Adjunct Professor Department of Health Services University of Washington MedicalResearch.com: What is the background for this study? Response: The background is that the most common experience of head injury with loss of consciousness is an apparent recovery. Sometimes this is very fast, sometimes it takes somewhat longer, but typically people return to their prior baseline. Nevertheless there is concern that the head injury may have set in motion processes that would lead to late life neurodegenerative conditions. This is bad enough for someone to deal with but it's made even worse if the head injury isn't even the victim's fault. Previous research has focused especially on Alzheimer's disease. A more limited research has focused on Parkinson's disease. We used data from three prospective cohort studies that included more than 7,000 people to study the relationship between head injury with loss of consciousness and subsequent risk of Alzheimer's and Parkinson's disease. We collected head injury exposure data at study enrollment, at a time when we administered cognitive tests and knew they did not have dementia, so our exposure data are not biased. Each of these studies also performed brain autopsies on people who died, and we evaluated data from more than 1500 autopsies. (more…)
AHA Journals, Author Interviews, CDC, Heart Disease / 11.07.2016

MedicalResearch.com Interview with: Suzanne Meredith Gilboa, PhD Epidemiologist at the Centers for Disease Control and Prevention’s National Center on Birth Defects and Developmental Disabilities MedicalResearch.com: What is the background for this study? What are the main findings? Response: Because of advancements in care, there has been a decline in mortality from congenital heart defects (CHD) over the last several decades. However, there are no current empirical data documenting the number of people living with CHD in the United States (US). The purpose of this study was to estimate the  congenital heart defects prevalence across all age groups in the US for the year 2010. Using prevalence data from Québec, Canada in the year 2010 as a foundation for a mathematical model, we estimated that approximately 2.4 million people (1.4 million adults, 1 million children) were living with CHD in the US in the year 2010. Nearly 300,000 subjects had severe CHD. Overall, there was a slight predominance of females compared to males. (more…)
Author Interviews, Cancer Research, Stem Cells / 11.07.2016

MedicalResearch.com Interview with: Cédric Blanpain, MD, PhD Professor of Stem Cell and Developmental Biology WELBIO, Interdisciplinary Research Institute (IRIBHM) Université Libre de Bruxelles (ULB) Belgium MedicalResearch.com: What is the background for this study? Response: Many cancers arise from tissues maintained by stem and progenitor cells that ultimately give rise to non-dividing terminally differentiated cells. However, little is known about the contribution of stem cells and progenitors to cancer initiation. During tumor initiation, cells targeted by oncogenic mutations undergo a series of molecular changes leading to their clonal expansion and the acquisition of invasive properties. How exactly oncogenic mutations impact on the rate of stem cell and progenitor division, and change the proportion of divisions that result in symmetric and asymmetric cell fate, allowing clonal expansion and tumor progression is poorly understood. In this new study, we define for the first time the clonal dynamics that lead to skin cancer initiation using the basal cell carcinoma, the most frequent tumor in humans, as a model. (more…)
Author Interviews, Biomarkers, Colon Cancer, Science / 11.07.2016

MedicalResearch.com Interview with: Jeanne Tie MBChB, FRACP, MD Division of Systems Biology and Personalised Medicine, Walter and Eliza Hall Institute of Medical Research Department of Medical Oncology, Western Health, St Albans, Victoria, Australia. Department of Medical Oncology, Faculty of Medicine, Dentistry and Health Sciences, University of Melbourne Parkville, Victoria, Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study investigated the ability of circulating tumor DNA (ctDNA) in detecting residual microscopic cancer after surgery with curative intent in patients with stage II colon cancer. Although the majority of patients with stage II colon cancer are cured by surgery alone, our ability to accurately predict the risk of cancer relapse based on current clinical and pathological criteria is imprecise. Population-based study indicated that adjuvant chemotherapy is given to up to 40% of stage II colon cancer patients, meaning that we are over-treating a significant number of patients with cytotoxic therapy. A better indicator of residual disease and recurrence would be very useful clinically. The current study collected tumor and blood samples from 230 patients with stage II colorectal cancer. A personalised assay was then designed to detect patient-specific tumor DNA in the plasma samples collected four to ten weeks after surgery. The presence of ctDNA (positive test) in the post-operative blood sample predicted recurrence in 100% of patients, while the relapse rate is only 10% in those with negative ctDNA test. We have also shown that the ctDNA test is a better predictor of recurrence than the standard clinic-pathological criteria. (more…)

MedicalResearch.com Interview with: Dr. Duong Nguyen, Medicine Professional Corporation MD,MSc(c),FRCSC,DipABOS,DipSportsMed(ABOS),FAAOS,CIME Diplomate of the American Board of Orthopaedic Surgery Subspecialty Board Certification in Sports Medicine Fellow of the American Academy of Orthopaedic Surgeons Certified Independent Medical Examiner (ABIME) Diplomate Sport & Exercise Medicine (CASEM) Arthroscopic & Reconstructive Shoulder,Elbow & Knee Surgery Medical Director / Urgent Sports Injury & Fracture Clinic MSc Candidate/ Clinical Epidemiology & Health Research Methodology Adjunct Clinical Professor - McMaster University Toronto, ON. MedicalResearch.com: What is the background for this study? What are the main findings? Response: ACL re-tear after surgery is a serious complication in the sports medicine world with many implications for the athlete such as lost game time, the morbidity of a second surgery and extended rehabilitation, lost scholarship, decreased self esteem and social isolation,as well as decreased academic performance. We found in our study that athletes who are less than 25, are female, and have a graft size less than 8 mm are at increased risk for ACL re-tear after surgery. (more…)
Author Interviews, Cancer, Cancer Research, UCLA / 11.07.2016

MedicalResearch.com Interview with: Karim Chamie MD, MSHS Department of Urology Jonsson Comprehensive Cancer Center David Geffen School of Medicine University of California at Los Angeles Los Angeles, California MedicalResearch.com: What is the background for this study? Response: With improved cancer outcomes, there are 14 million cancer survivors alive in the United States in 2012. That number is expected to increase to nearly 20 million by 2024. With such a large population, many of these cancer survivors are at risk for developing a second primary malignancy. Multiple primary cancers now account for approximately 17% of all incident cancers reported each year in the United States. Cancer survivors may be especially susceptible to developing second primary malignancies due to a variety of unique factors, including genetic syndromes, common etiologic exposures, and the late effects of chemotherapy and radiotherapy. Given the longer duration of cancer survivorship and the substantial proportion of survivors at risk for developing second primary malignancies, the incidence and mortality from second primary malignancies are likely to increase.

Asthma, Author Interviews, Environmental Risks / 11.07.2016

MedicalResearch.com Interview with: Jamie T Mullins PhD Environmental Economics and Applied Microeconomic Department of Resource Economics University of Massachusetts Amherst Amherst, MA 01003 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Episodic triggers of asthma are widely known, but the root causes of the condition still aren’t well understood. There is also very limited evidence on the long-term impacts of exposure to air pollution. Speaking to both issues, we find evidence linking the development of asthma to exposure to a significant air pollution event early in life. The 1952 London Smog provides a natural experiment for studying the underlying cause of asthma and the long-term effects of air pollution exposure, while limiting threats from statistical confounding. The London Smog (also called the “Great Smog”) dramatically increased concentrations of air pollution across the city in December of 1952. We compare the incidence of asthma among those exposed to the Great Smog in utero or the first year of life to those in relevant comparison groups, including those conceived after the incident and those residing outside the affected area at the time of the Smog.

Author Interviews, Infections / 11.07.2016

MedicalResearch.com Interview with: Hemilä Harri Hemilä, MD, PhD Department of Public Health, University of Helsinki MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our meta-analysis of 3 randomized controlled trials on zinc acetate lozenges was motivated by an early trial which indicated that zinc lozenges might be more effective for patients with allergies. We found that allergy, sex, age, and ethnic bacground did not influence the effect of zinc acetate lozenges. Thus, the average effect of 3 day reduction in colds seems to be applicable for a wide range of common cold patients. (more…)
Accidents & Violence, Author Interviews, Education, Geriatrics, Nursing / 10.07.2016

MedicalResearch.com Interview with: MedicalResearch.com: What is the background for this study? What are the main findings? Response: The impetus for this article was our experience from working at FAU’s Christine E. Lynn College of Nursing’s Louis and Anne Green Memory and Wellness Center with families as we conducted assessments of older adults referred to our program by family members or law enforcement. We realized that there is a need to educate nurses that a) they can help to identify persons who may be at risk for unsafe driving before accidents occur, and b) there are resources to help families and nurses navigate this challenging topic. This awareness is especially important for persons and friend/family members who find themselves trying to cope with a known or potential diagnosis of dementia. (more…)
Author Interviews, Brigham & Women's - Harvard, Pancreatic, Weight Research / 10.07.2016

MedicalResearch.com Interview with; Dr. Rakesh K. Jain, PhD A.W.Cook Professor of Radiation Oncology (Tumor Biology) Director, E.L. Steele Laboratory Department of Radiation Oncology Harvard Medical School and Massachusetts General Hospital Boston, MA 02114 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer death worldwide, and more than half of patients diagnosed with PDAC are overweight or obese. Among patients with PDAC, obesity more than doubles the already high risk of death, and our work aims to reveal the underlying mechanisms. Specifically, we identified that obesity increases desmoplasia – an accumulation of connective tissue and inflammation – hallmark of Pancreatic ductal adenocarcinoma and discovered underlying mechanisms. In our report published online in Cancer Discovery, we describe how interactions among fat cells, immune cells and connective tissue cells in obese individuals create a microenvironment that promotes tumor progression while diminishing the response to chemotherapy. We demonstrated the negative impact of obesity on numerous aspects of tumor growth, progression and treatment response in several animal models of pancreatic ductal adenocarcinoma and confirmed some of our findings in samples from cancer patients. Along with finding that tumors from obese mice or patients exhibited elevated levels of adipocytes or fat cells and of desmoplasia, both of which fuel tumor progression and interfere with treatment response, we identified the underlying causes. The elevated desmoplasia in obese mouse models of PDAC was caused by the activation of pancreatic stellate cells through the angiotensin II type-1 receptor (AT1) signaling pathway. This activation was induced by interleukin-1 beta (IL-1ß) produced by fat cells as well as the immune cells called neutrophils within tumors. Inhibiting AT1 signaling with losartan, which is used clinically to treat hypertension, or the blockade of IL-1ß reduced obesity-associated desmoplasia and tumor growth and increased the response to chemotherapy in the obese mouse model but not in normal weight animals. Analysis of tumors from human PDAC patients revealed increased desmoplasia and fat deposits in samples from obese patients, and data from more than 300 patients showed that excess weight was associated with a reduction in patients.

Author Interviews, Brigham & Women's - Harvard, Cost of Health Care, JAMA / 10.07.2016

MedicalResearch.com Interview with: Lisa Soleymani Lehmann, MD, PhD Associate Professor of Medicine and Medical Ethics Director, Center for Bioethics Brigham and Women's Hospital Harvard Medical School Boston, Massachusetts MedicalResearch.com: What is the background for this study? Response: The background for this study is the Choosing Wisely Campaign from the American Board of Internal Medicine (ABIM). This campaign has asked specialty boards to come up with lists of interventions (e.g., imaging, medications, tests) that patients and doctors should question. When it initially came out, we thought it was a great idea, but wondered if patients and doctors would agree that some of the interventions are low value. It’s hard to cut back on things that patients feel are valuable to their care, especially as patient ratings of their doctor’s care become part of hospital ratings and physician reimbursement.

MedicalResearch.com Interview with: Ruopeng An, PhD Assistant Professor Department of Kinesiology and Community Health College of Applied Health Sciences University of Illinois at Urbana-Champaign MedicalResearch.com: What is the background for this study? What are the main findings? Response: Sandwiches are a staple of the American diet. About one half of the U.S. adult population consumed one or more sandwiches on a daily basis. Sandwich consumption may profoundly influence people’s diet quality and calorie intake. (more…)
Author Interviews, NYU, Race/Ethnic Diversity, Sleep Disorders, Stroke, Weight Research / 09.07.2016

MedicalResearch.com Interview with: Azizi Seixas, Ph.D. Post-Doc Fellow Department of Population Health Center for Healthful Behavior Change NYU School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Compared with whites, blacks are disproportionately affected by strokes. The overwhelming prevalence of obesity among blacks compared to whites has been suggested as a possible explanation for the disproportionate rates of strokes among blacks compared to whites. Recent findings linking insufficient sleep and stroke as well as the disproportionate burden of insufficient sleep among blacks compared to whites might provide a unique mechanism explaining why blacks have higher rates of stroke. However, it is unclear whether insufficient sleep and obesity contributes to the higher rates of stroke among blacks compared to whites. To test our hypothesis, we utilized data from the National Health Interview Survey from 2004-2013 with a sample size of 288,888 individuals from the United States. Using Bayesian Belief Network (BBN) analysis, a form of machine learning analysis, we assessed the mediating effects of BMI on the relationship between short sleep duration (≤6 hrs. total sleep duration), long sleep duration (≥9 hrs. total sleep duration), and stroke, and whether race/ethnicity differences in obesity moderated these relationships.

Author Interviews, Cancer Research, CDC, HPV, Vaccine Studies / 09.07.2016

MedicalResearch.com Interview with: Laura J. Viens, MD Division of cancer prevention and control CDC MedicalResearch.com: What is the background for this study? What are the main findings? Response: We analyzed the most recent available data from 2008–2012 from CDC’s National Program of Cancer Registries (NPCR) and the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) program for HPV-associated cancers.
  • These data cover 99% of the US population.
  • These data represent the official federal statistics on cancer incidence (new cases).
  • Every year between 2008 and 2012, about 39,000 men and women were diagnosed with cancers associated with HPV, an overall increase when compared with the 33,000 cancers associated with HPV between 2004 and 2008.
  • 23,000 (13.5 per 100,000 population) among females and 15,793 (9.7 per 100,000 population) among males.

Author Interviews, Cancer Research, Diabetes, NYU, Sleep Disorders / 09.07.2016

MedicalResearch.com Interview with: Mr. Lloyd Gyamfi and Azizi Seixas, Ph.D. Post-Doc Fellow Department of Population Health Center for Healthful Behavior Change NYU School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: An association exists between unhealthy sleep duration (short:≤6 hrs. or long sleep: ≥ 9hrs.) and cancer. The specific link between cancer and diabetes is unknown. Evidence suggests that cancer and diabetes may share common risk factors such as age, gender, race, being overweight an alcohol use. Based on the data extracted from the National Health Interview Survey (NHIS) dataset (2004-2013) with a sample size of 283,086, it was identified that individuals who had a history of cancer and who reported long sleep duration did not have increased risk of diabetes diagnosis.

Author Interviews, CDC, Diabetes, Heart Disease, JAMA / 09.07.2016

MedicalResearch.com Interview with: Edward Gregg, PhD Chief of the Epidemiology and Statistics Branch Division of Diabetes Translation National Center for Chronic Disease Prevention and Health Promotion Centers for Disease Control and Prevention MedicalResearch.com: What is the background for this study? What are the main findings? Response: The research was led by the lead author, Karen R. Siegel, PhD, as part of her PhD graduate studies at Emory for her dissertation. Although subsidized foods are intended to ensure adequate availability of storable, staple foods, studies at the population level have linked these subsidies to risk of cardiovascular disease and type 2 diabetes. This study is the first of its kind to examine these relationships at the individual level – specifically, the relationship between diets made up of more subsidized foods, and an individual’s personal risks for developing cardiovascular disease and type 2 diabetes. The study design that was used here does not allow us to say that these subsidized foods specifically cause type 2 diabetes and cardiovascular disease. Rather, people whose diets contain more corn, soybean, wheat, rice, sorghum, dairy, and livestock products are at greater risk for type 2 diabetes and cardiovascular disease. According to this research, people whose diets contained more subsidized foods were on average younger, less physically active and more likely to be smokers. They also had much less income, education and food security - or the ability to get enough safe and healthy food to meet their dietary needs. (more…)
Author Interviews, OBGYNE / 09.07.2016

MedicalResearch.com Interview with: Annefleur de Bruijn MD VU Medical Centre Department of Gynecology Amsterdam, The Netherlands MedicalResearch.com: What is the background for this study? Response: Since 1995 uterine artery embolization has been described in patients with symptomatic fibroids. Uterine artery embolization is a less invasive treatment option compared to hysterectomy. Studies including several randomized controlled trials established uterine artery embolization as a valuable treatment. Earlier these trials reported outcomes in terms of health related quality of life, clinical outcomes, efficacy and cost effectiveness after 1, 2 and 5 years of follow-up. In the randomized EMMY trial, we analyzed these results again, currently 10 years after treatment. (more…)
Author Interviews, Education, NEJM / 09.07.2016

MedicalResearch.com Interview with: Marsha Regenstein, Ph.D, Professor From the Department of Health Policy and Management Milken Institute School of Public Health George Washington University Washington, DC MedicalResearch.com: What is the background for this study? Response: Despite the billions of dollars in public spending on graduate medical education (GME) in the United States, little is known about the true cost of training a resident, with the few studies that exist showing wide variation in their methods and results. At the same time, the U.S. appears to be producing too few primary care physicians to meet the health care needs of the population, and especially those who live in underserved areas with high health care needs and shortages of health professionals. The Teaching Health Center (THC) Graduate Medical Education funding program was established under the Affordable Care Act to increase the number of medical and dental residents training in six primary care specialties in underserved areas. The Teaching Health Center funding supports community-based residency training in settings such as Federally-qualified health centers, rural clinics, mental health clinics and other non-profit community-based organizations. Hospitals commonly serve as training partners, but THC funding goes directly to the community-based partner, bringing funding and training closer to the communities where underserved patients live. The Health Resources and Services Administration (HRSA), which manages and funds the program, set an interim payment of $150,000 per resident; currently, 59 THCs are training 690 residents in 27 states and the District of Columbia. The interim payment rate was based on the best available information at the time and was meant to cover the full cost of training a resident. (more…)
Author Interviews, Health Care Systems, Hospital Readmissions, Yale / 09.07.2016

MedicalResearch.com Interview with: Kumar Dharmarajan, MD, MBA Assistant Professor of Medicine (Cardiology) Cardiovascular Medicine: Center for Outcomes Research & Evaluation (CORE) Yale School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Programs from the Centers for Medicare and Medicaid Services simultaneously promote strategies to lower hospital admissions and readmissions. However, there is concern that hospitals in communities that successfully reduce admissions may be penalized, as patients that are ultimately hospitalized may be sicker and at higher risk of readmission. We therefore examined the relationship between changes from 2010 to 2013 in admission rates and thirty-day readmission rates for elderly Medicare beneficiaries. We found that communities with the greatest decline in admission rates also had the greatest decline in thirty-day readmission rates, even though hospitalized patients did grow sicker as admission rates declined. The relationship between changing admission and readmission rates persisted in models that measured observed readmission rates, risk-standardized readmission rates, and the combined rate of readmission and death.

MedicalResearch.com Interview with: Roberta Rizzo PhD Department of Medical Sciences Section of Microbiology University of Ferrara Ferrara, Italy MedicalResearch.com: What is the background for this study? Response: Infertility affects approximately 6% of 15-44 year old women or 1.5 million women in the US, according to the CDC. Approximately 25% of female infertility cases are unexplained, leaving women with few options other than expensive fertility treatments. Researchers are trying to identify factors and mechanisms at the basis of this condition. (more…)
Author Interviews, Blood Pressure - Hypertension, Vitamin D / 08.07.2016

MedicalResearch.com Interview with: Dr. Nicola Veronese University of Padova Department of Medicine - DIMED, Geriatrics Division Padova, Italy MedicalResearch.com: What is the background for this study? What are the main findings? Response: In the last 5 years, some studies investigated the possible association between hypovitaminosis D and orthostatic hypotension. However, all these studies were cross-sectional,  not disentangling if hypovitaminosis D precedes or follows orthostatic hypotension. In our work, we reported that low vitamin D at baseline predict the onset of orthostatic hypotension at follow-up in older people. This association was stronger in women than in men. (more…)

MedicalResearch.com Interview with: Dr. Michelle L. Holland The Blizard Institute, Barts and The London School of Medicine and Dentistry Queen Mary University of London London MedicalResearch.com: What is the background for this study? Response: There is strong evidence that the early life environment can influence lifelong health-a phenomenon termed ‘developmental programming.’ However, the mechanisms by which this occurs are poorly understood. Here, we set out to explore whether epigenetic marks-modifications to DNA that influence whether a gene is ‘on’ or ‘off,’ are altered in response to the early life environment and whether this relates to later life health.

Author Interviews / 07.07.2016

MedicalResearch.com Interview with: Sofiya Milman, MD, MS Assistant Professor of Medicine Divisions of Endocrinology and Geriatrics Albert Einstein College of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Aging is a major risk factor for most chronic diseases, including cancer, cardiovascular disease, diabetes, hypertension, stroke and osteoporosis. However, many very long-lived individuals delay the onset or never develop age-related diseases. This study compared groups of individuals with exceptional longevity (age ≥95 years) of different genetic and ethnic backgrounds to younger referent groups without familial longevity (age 49-93 years). Long-lived individuals from different groups similarly delayed the age of onset of cancer, cardiovascular disease, hypertension, osteoporosis, and stroke. For example, cancer onset was delayed by 30 years and cardiovascular disease by 24 years. The risk of developing any age-related disease was on average 80% lower in individuals with exceptional longevity compared to referents. (more…)

MedicalResearch.com Interview with: Amanda M. Perak, MD Division of Cardiology, Ann & Robert H. Lurie Children’s Hospital of Chicago, and Department of Preventive Medicine Northwestern University Feinberg School of Medicine Donald M Lloyd-Jones, MD/ScM (senior author) Senior Associate Dean for Clinical and Translational Research; Chair, Department of Preventive Medicine Director, Northwestern University Clinical and Translational Sciences Institute (NUCATS) and Eileen M. Foell Professor Professor in Preventive Medicine-Epidemiology and Medicine-Cardiology MedicalResearch.com: What is the background for this study? Response: Heterozygous familial hypercholesterolemia, or FH, affects up to 1 in 200 individuals in the United States. FH is a genetic disorder that should be suspected in individuals with very high levels of low-density lipoprotein cholesterol (LDL-C; at least 190 mg/dL) plus a first-degree relative with similar degree of high cholesterol or with premature coronary heart disease. Individuals with FH are exposed to high levels of "bad" cholesterol from birth, so if they are not treated with cholesterol-lowering therapy, they are at elevated risk for atherosclerotic cardiovascular disease (ASCVD; diseases related to hardening of the arteries, including heart attack and stroke). However, these risks previously had not been well quantified in untreated individuals with familial hypercholesterolemia in the general US population. (more…)
