What are the main findings? Response: Short sleep duration and sleep fragmentation are associated with adverse health outcomes including cardiovascular disease, diabetes, hypertension, certain cancers, and mental health challenges such as depression and anxiety. Avoiding the use of alcohol, caffeine, and nicotine close to bedtime represent modifiable behaviors that can improve sleep. Nonetheless, among community dwelling adults (e.g., adults in their natural bedroom environment as opposed to research laboratories) and specifically African Americans, there is a lack of longitudinal research investigating the use of these substances and the associations with objective measures of sleep..

Response: Almost half of all drug recalls are due to cardiac toxicity that was not picked up during early screens. These human cardiac liabilities can go undetected because historically it has been challenging to predict how human hearts will respond to potentially cardiotoxic drugs despite rigorous testing in both animals and in vitro systems throughout drug development. Traditional in vitro systems and animal models do not translate well to humans, and human donor tissue availability is limited for in vitro testing. There is great potential for human-induced pluripotent stem cell cardiomyocytes (iPSC-CMs) to bridge this human translation gap, but it’s been a challenge to train these cells to recapitulate pharmacology seen in mature human heart cells. This stems from the fact that existing experimental models utilize immature human iPSC-CMs which lack relevant physiological hallmarks of adult human cardiac muscle and therefore fail to predict drug responses seen in the clinic.

What are the main findings? Response: Traditionally, displaced 2-part humerus fractures have been operatively treated using a metal plate and screws. However, there are no studies showing a benefit of operation of those fractures. Therefore, we were interested in investigating, in a direct comparison between operation and non-operative treatment, whether there was a difference in patient-reported function, pain and health-related quality of life two years after the fracture. In this Nordic research collaboration http://nitep.eu/en/ between Finland, Sweden, Estonia and Denmark we showed that there is no difference in functional results between operative and non-operative treatment in persons aged 60 or more with displaced proximal humerus fractures. In the study, only fractures with a significant displacement between bone fragments were included. In the non-operative treatment group, patients used a collar and cuff sling for three weeks and underwent instructed physiotherapy.

MedicalResearch.com Interview with: Ambry GeneticsNancy Niguidula, MS, DPH Doctorate in Public Health in Toxicology Ambry Genetics   MedicalResearch.com: What is the background for this study? Response: The clinical presentations of many inherited cardiovascular conditions overlap; thus, genetic testing may clarify diagnoses, help with risk stratification, facilitate appropriate clinical management decisions, and aid in identifying asymptomatic, at-risk relatives. A large number of professional societies have developed practice guidelines and recommendations for genetic testing of cardiovascular diseases. These include international and collaborative expert panels that establish genetic screening and treatment recommendations by drawing on evidence-based medicine. To further strengthen the clinical utility of cardiovascular genetic testing, the American College of Medical Genetics and Genomics (ACMG) published a guideline for 59 genes with clinical actionability that should be reported if found on whole exome sequencing, even when unrelated to the testing indication.

Response: The war against cancer in general, and melanoma in particular, has advanced over the years through a variety of treatment modalities, such as surgery, chemotherapy, radiation therapy and immunotherapy. The immune checkpoint inhibitors brought a breakthrough solution for advanced melanoma patients, but only a low percentage of those respond to this therapy, developing resistance and being affected by severe side effects. Despite the success of several vaccines against viral diseases, this success has not been materialized yet against cancer. This study led by my lab at Tel Aviv University, and Helena Florindo’s lab at the University of Lisbon, describes the development of an effective nano-vaccine against melanoma, that also sensitizes the immune system to immunotherapies. This nano-vaccine prevented melanoma, and also led to remarkable tumor inhibition and prolonged survival in mice already affected by this disease.

Response: Concussion is defined based on the manifestation of observable signs and symptoms (e.g., dizziness, difficulty with concentration, loss of consciousness, inter alia). A non-concussive head injury is when someone hits their head but does not exhibit the signs and symptoms of concussion -- IE concussion is defined by observable signs, and sub-concussive is defined as sustaining  head impacts similar (in magnitude and mechanism) to those sustained with concussion without observable signs and/or symptoms. These hits are a problem not only in football, but also with IED/bomb blasts experienced during war and potentially rugby.

Dr. Cheng[/caption] Dr. Alan Cheng, MD MBA Vice President at Medtronic Clinical Research and Therapy Development, Cardiac Rhythm Management Medtronic, Minnesota 55112  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Ventricular arrhythmias can be life threatening among patients with certain types of heart disease. While implantable cardioverter defibrillators (ICDs) have become the primary means in managing these events, we still don’t fully understand when ventricular arrhythmias occur and whether they are just random events that occur at any time of the day. We pooled patient-level data from 6 prospective studies of ICD recipients and leveraged the continuous monitoring features of the ICD to understand when ventricular arrhythmias occur. Across almost 4000 patients with almost 2 years average follow up from the time of implant, we saw that ventricular arrhythmias aren’t randomly distributed throughout the day. In fact, there is a predilection for these events to occur during normal waking hours as compared to the times of the day when most patients are asleep. Additionally, we found that across the year, the spring season had higher rates of arrhythmia occurrence when compared to summer. We didn’t observe any differences in arrhythmia occurrence by the days of the week or months of the year. This analysis is not the first to explore this question but it is the largest to date.

MedicalResearch.com Interview with: Hong Liang Tey MBBS, FRCP Head of Research Division and Senior Consultant, National Skin Centre, Singapore Adj Assoc Prof., Yong Loo Ling School of Medicine, National University of Singapore Asst Prof., Lee Kong Chian School of Medicine, Nanyang Technological University, Singapore  MedicalResearch.com: What is the background for this study? We developed dissolving microneedles embedded with a medication, triamcinolone, as a novel treatment option for patients with keloids and evaluated its efficacy and safety in a clinical trial.  Background: Keloids are a common skin disorder and itch and pain afflicts up to 80% of patients. The first-line and typically the only treatment option is multiple repeated intra-lesional corticosteroid injections by dermatologists or specially-trained nurses. However, many patients are unable to undergo this treatment. Typically, such patients
  • Are unable to tolerate the pain of conventional intra-lesional injection, as keloids are inherently hypersensitive. The problem is exacerbated by the fact that repeated monthly injections are required to achieve a response. In addition, children cannot tolerate pain and cannot undergo such injections.
  • Have keloids on the mid facial region, where injection carries a risk of causing blindness.
  • Are unable to afford the time and cost of repeated travelling to see a dermatology doctor or nurse for the injections. These include patients residing or working overseas.
  • Have mid-sternum protrusive scars after cardiac arterial bypass surgery, and painful injections may trigger another heart attack.

Meister Child Health Evaluation and Research Center University of Michigan Ann Arbor, Michigan MedicalResearch.com: What is the background for this study?   Response: Tonsillectomy is one of the most common surgeries performed in children. It is also one of the most common reasons children are prescribed opioids, even though randomized trials suggest that non-opioids like ibuprofen are equally effective for pain control. We were interested in understanding whether it is possible to safely reduce opioid exposure after tonsillectomy in children without increasing the risk of complications such as emergency department visits for uncontrolled throat pain, which could lead to dehydration.

What are the main findings? Response: We know that the denser (stronger) your bones are, the less likely they are to break (fracture). We also have reliable evidence that later maturing adolescents tend on average to have lower bone density than their earlier maturing peers. We wanted to find out how the timing of puberty might influence the development of bone density throughout adolescence and into early adult life. We did this by following up a large group of young people born in the early 90s around Bristol, UK that took part in a unique study (the Children of the 90s study) that included repeated density scans over a 15-year period from age ten to 25. We found that those later maturing adolescents that got their growth spurt at an older age tended to catch-up to some degree to their earlier maturing peers during puberty however, they continued on average to have lower bone density than average for several years into adulthood.

Guy Jr., PhD, MPH Senior Health Economist Division of Unintentional Injury CDC Dr. Gery Guy[/caption] Gery P. Guy Jr., PhD, MPH Senior Health Economist Division of Unintentional Injury Prevention CDC  MedicalResearch.com: What is the background for this study? Response: In 2017, among the 70,237 drug overdose deaths in the United States, 47,600 (67.8%) involved prescription or illicit opioids. Distribution of the opioid receptor antagonist naloxone to reverse overdose is a key part of the public health response to the opioid overdose epidemic. The 2016 CDC Guideline for Prescribing Opioids for Chronic Pain recommended clinicians consider offering naloxone when overdose risk factors, such as history of overdose or opioid use disorder, higher opioid dosages, or concurrent benzodiazepine use, are present. However, recent analyses examining pharmacy-based naloxone dispensing are lacking. To address this gap and to inform future overdose prevention and response efforts, CDC examined trends and characteristics of naloxone dispensed from retail pharmacies at the national and county level in the United States.

MedicalResearch.com Interview with: [caption id="attachment_50631" align="alignleft" width="165"]Matthew Campbell, PhD Smurfit Institute of Genetics Trinity College Dublin Dublin Dr. Campbell[/caption] Matthew Campbell, PhD Smurfit Institute of Genetics Trinity College Dublin Dublin MedicalResearch.com: What is the background for this study? What are the main findings? Response: Age related macular degeneration (AMD) is the most common form of central retinal blindness in the world. However the underlying causes and initiating factors for disease progression are still not clear. It is classically a disease of the outer retina, where cells called retinal pigment epithelial (RPE) cells degenerate. However, our findings suggest that some of the early initiating events that promote AMD progression are actually coming from the inner retina and more specifically the microvasculature of the inner retina. We discovered that a gene called claudin-5 appears to be regulated by a circadian rhythm that in turn can regulate what gets into and out of the retina on a daily basis. Dysregulating the levels of this component made the inner retinal blood vessels marginally leaky and promoted a pathology that was AMD-like in animal models.  We also showed that the blood vessels of the retina appear to be highly dynamic in human subjects and can appear leakier at different times of the day, likely a mechanism that allows for clearance and replenishment of material into and out of the retina.  It is this process we believe breaks down in early AMD.

MedicalResearch.com Interview with: [caption id="attachment_50628" align="alignleft" width="154"]Auyon Siddiq PhD Assistant Professor/INFORMS Member Decisions, Operations & Technology Management  UCLA Anderson School of Management Dr. Siddiq[/caption] Auyon Siddiq PhD Assistant Professor/INFORMS Member Decisions, Operations & Technology Management UCLA Anderson School of Management MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Medicare Shared Savings Program (MSSP) was created under the Patient Protection and Affordable Care Act to control escalating Medicare spending by incentivizing providers to deliver healthcare more efficiently. Medicare providers that enroll in the MSSP earn bonus payments for reducing spending to below a risk-adjusted financial benchmark that depends on the provider's historical spending. To generate savings, a provider must invest to improve efficiency, which is a cost that is absorbed entirely by the provider under the current contract. This has proven to be challenging for the MSSP, with a majority of participating providers unable to generate savings due to the associated costs. This study presents a predictive analytics approach to redesigning the MSSP contract, with the goal of better aligning incentives and improving financial outcomes from the MSSP. We build our model from data containing the financial performance of providers enrolled in the MSSP, which together accounted for 7 million beneficiaries and over $70 billion in Medicare spending.

Response: We were interested, generally, in the association between meat consumption and breast cancer risk. Epidemiological studies of red meat consumption and risk of breast cancer are still inconsistent, although red meat has been identified as a probable carcinogen. In addition, there is not much evidence on the association between poultry consumption and breast cancer risk. We studied around 42,000 women ages 35-74 from across the US who are enrolled in the Sister Study cohort. Women provided self-reported information on meat consumption at baseline and were followed for 7.6 years on average.

What are the main findings? Response: Alcohol, tobacco, and cannabis are the most commonly used substances during pregnancy. High alcohol consumption has been linked with preterm birth, and tobacco and/or cannabis use is associated with low birth weight. Much of what we know about predictors of drug use during pregnancy comes from the United States and Australia, with limited studies in Canada. The objective of our study was therefore to assess the relative effects of socioeconomic, demographic, and mental health risk factors associated with drug use during pregnancy. Our retrospective cohort study consisted of 25,734 pregnant women from Southwestern Ontario. We found that maternal depression was the top risk factor associated with all three substances. Compared to women who were not depressed during their pregnancy, women who were depressed were 2.2 times more likely to use alcohol (95% CI: 1.6, 2.9), 1.7 times more likely to smoke tobacco (95% CI: 1.5, 2.0), and 2.6 times more likely to use cannabis (95% CI: 2.0, 3.4).

Piper, PhD, MS Department of Basic Sciences Geisinger Commonwealth School of Medicine Scranton, PA 18509 Dr. Piper[/caption] Brian J Piper, PhD MS Department of Medical Education Geisinger Commonwealth School of Medicine Scranton, Pennsylvania  MedicalResearch.com: What is the background for this study? Response: All states have a Prescription Monitoring Program to collect data about controlled substance prescriptions. Maine also had a Diversion Alert Program to obtain information about arrests involving prescription and illicit drugs. Buprenorphine is a treatment for an opioid use disorder. Naloxone is an opioid antagonist. Prior pharmacoepidemiology research found that buprenorphine accounted for half of prescriptions for males in their twenties in Maine.1 This study examined the current status of the opioid crisis using three complementary data sources: 1) Arrests as reported to the Diversion Alert Program; 2) Medical opioid use as reported by the Drug Enforcement Administration; and 3) Overdoses as reported to the medical examiner.

What types of skin cancers are linked to these genes? Response: Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) collectively referred to as “keratinocyte cancers” are the commonest forms of cancers of the skin. Although these cancers are less aggressive than melanoma, due to their large numbers, they pose a significant burden to the healthcare expenditure. Also, these cancers are relatively understudied when compared with melanoma. Notably, BCC and SCC are not routinely reported in cancer registries. In Australia, Medicare data are used to estimate the incidence and costs associated with these cancers. Expenditure in Australia for the diagnosis, treatment and pathology, almost exceeds $700 million for both BCC and squamous cell carcinoma. In Unites States, the average annual cost for skin cancer including melanoma is approximately $8.1 billion. Previous research has led to identification of 29 BCC and 11 squamous cell carcinoma genetic risk variants and 7 of them overlap with both BCC and SCC risk. So, to strengthen the preventive efforts and to reveal new therapeutics, it is very timely and critical to explore more on the genetic susceptibility of these deadly cancers. We analysed ~48,000 cancer cases with ~630,000 skin cancer free controls from European ancestry population in Australia, UK and USA.

What are the main findings?  Response: We have previously found in this same eastern Finnish male study population that higher egg intake was associated with lower risk of developing dementia and with better performance in tests assessing cognitive capacity. Eggs are a major source of choline, especially phosphatidylcholine, and choline (which is an essential nutrient) is necessary for the formation of acetylcholine, which is a neurotransmitter. Earlier studies have linked choline intake with better cognitive processing but there was no information whether choline intake would also be associated with lower risk of developing dementia. So the purpose of our current study was to investigate whether higher choline intake would associate with better cognitive performance and with lower risk of dementia, which would support our previous findings with egg intake. And in the current study we did find that especially higher phosphatidylcholine intake was associated with a lower risk of developing dementia and also with better performance in tests measuring memory and linguistic abilities of the men in the study.

Kociolek, MD MSCI Attending Physician, Division of Infectious Diseases, Associate Medical Director of Infection Prevention and Control, Ann & Robert H. Lurie Children’s Hospital of Chicago Assistant Professor of Pediatrics Northwestern University Feinberg School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Clostridioides (Clostridium) difficile colonization is very common among infants, yet infants almost never develop symptoms of infection. In adults, it is known that immunity against the toxins that C. difficile produces protect against C. difficile infection (CDI). Our goal was to determine whether or not infants who become colonized with C. difficile develop an immune response against these toxins. We collected stool from healthy infants at multiple time points during the first year of life to determine whether or not they became colonized with C. difficile. Then at 9-12 months old, we collected blood to see if we can identify antibodies in their blood that protect against these toxins. We discovered that colonization with C. difficile during infancy was strongly associated with the development of antibodies. These antibodies were able to protect against the harmful effects of these toxins in a laboratory cell culture model.
Author Interviews, Cancer Research, JAMA, MRI, Prostate Cancer / 07.08.2019

MedicalResearch.com Interview with: Dr Martha Elwenspoek PhD Research Associate in Epidemiology and Health Services Research NIHR CLAHRC West, Bristol MedicalResearch.com: What is the background for this study? Response: Prostate cancer is one of the most common cancers in men. Prostate cancer is usually diagnosed by taking 10 to 14 systematic samples from the prostate guided by ultrasound. However, these biopsies are unpleasant for patients, can miss cancer even when it’s present, can misclassify the severity of the cancer, and can cause side effects, such as bleeding and infection. If biopsies could be targeted better, men wouldn’t have to undergo so many and there would be less risk of getting a misleading result. Multiparametric MRI (mpMRI) scans are sometimes used before doing a biopsy to help diagnose prostate cancer, and while this approach is now being recommended by the UK National Institute for Clinical Excellence (NICE) their use isn’t widespread.

Response: As has been well established, mortality due to opioids has been increasing rapidly in recent years. We were interested in understanding whether mortality rates may be high among workers in certain industries and occupations for two primary reasons. First, if we were to find that mortality rates differed according to industry and/or occupation it might indicate that some aspect of these industries and occupations put workers at elevated risk for opioid-related overdose death. Second, interventions could be created to target these workers and hopefully prevent more deaths.

What are the main findings? Response: I'm a sleep researcher and I wanted to find the link between warm bath and sleep. Body temperature which is involved in the regulation of the sleep/wake cycle, exhibits an endogenous circadian cycle, that is a 24-hour pattern, being highest by 2-3°F in the late afternoon/early evening than during sleep when it's lowest. The average person’s circadian cycle is characterized by a reduction in core body temperature by ~ 0.5 to 1° F the hour or so before one’s usual sleep time, dropping to its lowest level between the middle and later span of nighttime sleep. It then begins to rise, acting as a kind of a biological alarm clock wake-up signal. The temperature cycle leads the sleep cycle and is an essential factor in achieving rapid sleep onset and high efficiency sleep.

MedicalResearch.com Interview with: [caption id="attachment_50581" align="alignleft" width="86"]Maria S. Altieri, MD, MS Invasive surgery fellow Washington University, St. Louis, MO Dr. Altieri[/caption] Maria S. Altieri, MD, MS Invasive Surgery Stony Brook, NY MedicalResearch.com: What is the background for this study? What are the main findings? Response: For majority of residents, training years coincide with prime child bearing years.  Historically, surgical residency has not been conducive for having children, as it is one of the most demanding experiences, requiring long hours, high stress levels, and the acquisition of clinical and technical skills over a short period of time. However, with recent trends towards a more favorable work-life balance and the 80-hour work week, more male and female residents are having children or considering having children during training.  Thus, the topic of parental leave during residency is becoming more fundamental.  However, there is little research on the attitudes of residents towards their pregnant peers and parental leave. We wanted to examine the perceptions of surgical trainees towards parental leave and pregnancy during residency.  Through understanding the perceptions of current residents, obstacles could be identified which could lead to potential changes in policies that could help to normalize parenthood and parental leave during surgical training.

Link, PhD Department of Sociology, Anthropology, & Criminal Justice Rutgers University Camden, NJ 08102 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Much literature documents the physical and mental health problems ailing prisoners and those incarcerated in jails. Some research finds that incarceration can bring about or exacerbate these mental and physical health conditions. Beginning from this premise, we ask how this damaged health status influences former prisoners’ ability to return home and remain crime free. We examined physical health limitations and depression among a longitudinal sample of prisoners in twelve U.S. states and found that both dimensions of health problems lead to further criminal behavior and in turn reincarceration. This effect is of health conditions is indirect; it affects crime and reincarceration through adverse impacts on employment and family relationships—factors long known to be related to criminal offending. In this way, we now know that not only can incarceration lead to health problems, but health problems can lead to incarceration. This is important in a society with leading incarceration levels and wide health disparities across race and socioeconomic status.

MedicalResearch.com Interview with: Kang Lee, PhD Dr Eric Jackman Institute of Child Study University of Toronto Toronto, Canada MedicalResearch.com: What is the background for this study? Response: We use a technology called transdermal optical imaging I and my postdoc invented to record facial blood flow using a regular video camera on the smartphone. This technology capitalizes on the fact that light travels beneath the facial skin and reflect off the hemoglobin under the skin. Our technology captures the minute reflected photons to decode facial blood changes due to our pulses and other physiological activities. Using machine learning, a neural network model learns to use the facial blood flow to predict blood pressures taken with a FDA approved scientific blood pressure measurement instrument. We then use the final model to predict the blood pressures of a new group of participants whose data had never been used in the model training.

Hoffman, Ph.D. Research Fellow Recovery Research Institute Center for Addiction Medicine Massachusetts General Hospital Harvard Medical School Dr. Hoffman[/caption] Lauren A. Hoffman, Ph.D. Research Fellow Recovery Research Institute Center for Addiction Medicine Massachusetts General Hospital Harvard Medical School MedicalResearch.com: What is the background for this study?   Response: In 2017, an estimated 11.4 million Americans reported past-year opioid misuse1 and opioid-related overdose accounted for more than 47,000 deaths2. Prior research has helped further our understanding of the prevalence and consequences of opioid misuse, but we know substantially less about recovery from opioid use problems. Recovery-focused research conducted to-date has largely focused on alcohol use disorder, the most common type of substance use disorder. Characterizing recovery from opioid use problems and the pathways that individuals take to resolve such problems can ultimately help identify effective ways to address opioid misuse. Using data from the first national probability-based sample of US adults who have resolved a significant substance use problem (National Recovery Survey3), we provide the first national prevalence estimate of opioid recovery, and characterize treatment/recovery service use and psychological well-being in individuals who resolved a primary problem with opioids, relative to individuals who resolved a primary alcohol problem. We focused our cross-sectional investigation of service use and well-being on 2 time-horizons associated with continued vulnerability: <1 year since problem resolution (early-recovery) and 1 – 5 years since problem resolution (mid-recovery).

MedicalResearch.com Interview with: Hans Bisgaard, DMSc, MD Head of COPSAC, Professor Professor of Pediatrics, University of Copenhagen Founder and Head of the Copenhagen Prospective Studies on Asthma in Childhood; Gentofte Hospital, University of Copenhagen and Naestved Hospital MedicalResearch.com: What is the background for this study? Response: Enamel defects is a global health challenges affecting typically 1/3 of school children and more in some regions. It leads to break down of the teeth and caries later on. MedicalResearch.com: What are the main findings? Response: Supplementation with high-dose vitamin D compared to standard dose in the third pregnancy trimester in a mother child cohort of 588 pairs lead to a significant reduction of enamel defects. Enamel defects was found in 28% of children by age 6 after standard dose of vitamin D supplementation (400 i.u.), compared to 15% after 7-fold higher dose vitamin D.

H. Chan School of Public Health Dr. Chaudhary[/caption] Muhammad Ali Chaudhary, MD Research Scientist Center for Surgery and Public Health Department of Surgery Brigham and Women’s Hospital Harvard Medical School Harvard T. H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: Many studies have documented disparities in cardiovascular care for minorities, specifically African Americans compared to white patients. Coronary artery bypass grafting (CABG) is a common procedure in the United States, and the outcomes and post-surgical care for African Americans tend to be worse. We examined whether patients insured through TRICARE — a universal insurance and equal-access integrated healthcare system that covers more than 9 million active-duty members, veterans and their families — experienced these disparities. We found no racial disparities in quality-of-care outcomes, providing insights about the potential impacts of universal insurance and an equal-access health care system. The study included 8,183 TRICARE patients, aged 18-64, who had undergone CABG. The study took its data from TRICARE health care claims from the Military Health System Data Repository for the years of 2006 to 2014.
