MedicalResearch.com Interview with: Lana Zhovtis Ryserson, MD Assistant Professor, Department of Neurology NYU Langone Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Natalizumab is an effective therapy of relapsing remitting multiple sclerosis dosed at 300mg every 4 weeks. However it is associated with a potentially deadly infection - progressive multifocal leukoencephalopathy. In order to mitigate this risk, clinicians have adopted an approach of infusing the medication less frequently, a strategy which has become known as Extended Interval Dosing (EID). The TOUCH database is US mandatated risk evaluation and mitigation program which is the largest database available to assess PML risk for patients on EID schedule. Previous analysis of this database in 2017, showed a significant risk reduction of PML in patients utilizing extended interval dosing schedule. The aim of the current study was to update on this analysis with another year of data. (more…)

Genetically Fast-Changing Superbugs at Hospitals Require More Stringent Cleaning MethodsThe number of deaths caused by resistant bacteria is expected to reach 10 million by 2025, according to the Centers of Disease Control and Prevention. A highly resistant bacteria found in hospitals - Klebsiella pneumoniae - is now a big global threat, according to a recent (April, 2019) study published by researchers from University College London. Researchers have issued a warning that more stringent cleaning of infectious wards and new air disinfection protocols are key to battling the bug. This is because this bacteria possesses the ability to change genetically at an alarming rate, adapting and essentially nullifying the effect of all current antibiotics. (more…)

MedicalResearch.com Interview with: John P. Galiote, M.D. Neonatologist at Children’s National-Virginia Hospital Center NICU Michelande Ridoré, MS, NICU Quality improvement lead at Children’s National   Lamia Soghier, M.D., MEd, Children’s National NICU Medical Director MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study emphasizes the importance of team work and real-time communication in a quality-improvement project within the neonatal intensive care unit (NICU) setting. Through bedside huddles, weekly reviews of apparent cause analysis reports reducing the frequency of X-rays and the creation of an Airway Safety Protection Team, we were able to focus not only on  reducing unintended extubations, but also on the quality-improvement project’s effect on our staff. Adhering to simple quality principles enabled us to ensure that all members of our staff were heard and had a positive effect on the progress of our project. This allowed us to implement and sustain a series of simple changes that standardized steps associated with securing and maintaining an endotracheal tube (ET). Unintended extubations are the fourth-most common adverse event in the nation’s NICUs. Continual monitoring via this quality-improvement project allowed us to intervene when our rates increased and further pushed our unintended extubation rate downward. (more…)

MedicalResearch.com Interview with: David Strauss, MD, PhD Director, Division of Applied Regulatory Science U.S. Food and Drug Administration Center for Drug Evaluation and Research MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is unknown whether most active ingredients in sunscreens are absorbed. FDA has provided guidance that sunscreen active ingredients with systemic absorption greater than 0.5 ng/mL or with safety concerns should undergo nonclinical toxicology assessment including systemic carcinogenicity and additional developmental and reproductive studies. This randomized clinical trial demonstrated systemic exposure of 4 commonly used sunscreen active ingredients on application of sunscreen products under maximal use conditions consistent with current sunscreen labeling. All 4 sunscreen active ingredients tested resulted in exposures exceeding 0.5 ng/mL.  (more…)
Allergies, Author Interviews, Immunotherapy, JAMA / 06.05.2019

MedicalResearch.com Interview with: Marcus S. Shaker, MD Associate Professor of Pediatrics Associate Professor of Community and Family Medicine Dartmouth-Hitchcock Medical Center MedicalResearch.com: What is the background for this study? Response: There are two peanut allergy treatments that are being evaluated for potential FDA approval—an orally administered treatment and an epicutaneous (skin based) treatment.  Both have tremendous potential benefit.  The focus of our study was to explore the range of health and economic benefits in terms of establishing pathways for how each therapy could be cost effective. We want to be clear that our purpose was not to suggest one therapy is or is not cost effective at present.  That would be a ridiculous statement to make regarding two treatments that not only lack FDA approval, but do not have established pricing.  Rather, we used preliminary inputs that are presently available to create as robust a model as we could to better determine the individual paths that would make them more or less cost-effective.

Author Interviews, Brigham & Women's - Harvard, Education, JAMA / 06.05.2019

MedicalResearch.com Interview with: Arabella L. Simpkin,  MD, MMSc Associate Director, Center for Educational Innovation and Scholarship, MGH Associate Program Director, Education and Curriculum, Internal Medicine Residency, MGH Instructor in Medicine, Harvard Medical School Boston, MA 02114 MedicalResearch.com: What is the background for this study? Response: The academic health care environment has changed in unprecedented ways over several decades, with mounting evidence that faculty are becoming increasingly more unhappy, dissatisfied, and burnt out in their work. Concern for faculty wellbeing is high, with much speculation about causes of burnout. Comprehending what affects satisfaction at work in academic health care centers is critically important to stem this epidemic of discontent. For physicians, satisfaction has been reported to be associated with quality of care delivered, particularly as measured by patient satisfaction; faculty retention and job satisfaction are intricately linked, with dissatisfied physicians more likely to leave the profession and to discourage others from entering. Other industries that have suffered similar rises in employee discontent have found that demonstration of respect is the most important leadership behavior in improving employees satisfaction. To our knowledge this factor has not been looked at in healthcare professionals. To address this gap, we sought to determine key variables influencing satisfaction at work for faculty in a large academic medical center in the United States. (more…)

MedicalResearch.com Interview with: Jan Klimas, PhD, MSc Senior Postdoctoral Fellow BC Centre on Substance Use (BCCSU) Vancouver, BC MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Some individuals prescribed opioid analgesic medications for pain develop opioid use disorder. So, much research has been conducted to develop strategies to identify patients who can be safely prescribed opioid analgesics. However, this research has not been critically reviewed through rigorous quality assessment. This study therefore sought to identify signs, symptoms & screening tools to identify patients with pain who can be safely prescribed opioids  (more…)

Author Interviews, CDC, Emergency Care, Occupational Health, Opiods / 02.05.2019

MedicalResearch.com Interview with: Sophia K. Chiu, MD Epidemic Intelligence Service, CDC Division of Surveillance, Hazard Evaluations, and Field Studies National Institute for Occupational Safety and Health CDC  MedicalResearch.com: What is the background for this study? Response:  Responders across the United States are reporting work-related health effects during incidents in which suspected opioids (including fentanyl) and other illicit drugs such as cocaine, methamphetamine, cathinones, and synthetic cannabinoids are present, often as a mixture. These health effects have interfered with responders’ ability to perform their job duties. Since 2018, a number of responder organizations have requested that NIOSH investigate the health effects experienced by emergency responders during these response incidents. These organizations are looking for ways to protect their responders and prevent the symptoms responders have reported experiencing, so that they can in turn better serve the public. NIOSH’s goal is to increase awareness among responders of how they can remain safe while providing the care the public needs. (more…)
Author Interviews, Genetic Research, PNAS / 02.05.2019

MedicalResearch.com Interview with: Dr. Casey Trimmer, PhD Geneticist, was a post-doctoral fellow at the Monell Center when the research was conducted MedicalResearch.com: What is the background for this study?   Response: We detect odors using 400 different types of sensor proteins, called olfactory receptors, in our noses. An odor molecule activates a specific combination of these receptors, and this pattern of activation gives us information on what we're smelling--whether its floral or smoky, intense or weak, and how much we like it. However, how the system translates receptor activation to these perceptual features is largely unknown. Here, we take advantage of the extensive genetic variation in the OR gene family to understand the contribution of individual ORs to odor perception. By studying cases where the function of a particular OR is lost, we can examine what kinds of perceptual alterations occur, allowing us to link receptor to odor and understand what kind of information the receptor is encoding. Data linking genetic variation to perceptual changes exist for only 5 ORs. Here, we examined the perceived intensity and pleasantness of 68 odors in 332 participants. We used next-generation genome sequencing to identify variants in 418 OR genes and conducted a genetic association analysis to relate this variation to differences in odor perception. We then use a cell-based assay to examine receptor function and investigate the mechanisms underlying our associations. Finally, we examined the contribution of single OR genotype, genetic ancestry, age, and gender to variations in odor perception. (more…)

MedicalResearch.com Interview with: Igor Snast, MD Department of Dermatology Rabin Medical Center–Beilinson Hospita Israel.  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Acne is the most common skin disorder among adolescents. Obesity has been suggested to promote acne, however various studies evaluating the relationship between obesity and acne have yielded contradictory outcomes. Our population-based study demonstrates that overweight, obese and severely obese youths have decreased odds of having acne (20%, 35% and 50% respectively) compared to normal-weight subjects. (more…)
Author Interviews, Infections, JAMA / 01.05.2019

MedicalResearch.com Interview with: Nicholas B. DeFelice, PhD Department of Environmental Medicine & Public Health Icahn School of Medicine at Mount Sinai New York, New York MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Effective allocation of public health resources during an outbreak is complicated and often reactive. Thus, it is important that we develop quantitative tools that can accurately and rapidly forecast the progression of an outbreak and provide decision support. Recently, several advancements have been made in the realm of infectious disease forecasting: it is a field that is growing in exciting directions. However, for these forecasting tools to work in real time, we must understand how the forecasting apparatus and observational network work in real time to ensure they are sufficient to support accurate operational predictions. We previously showed that accurate and reliable forecasts of West Nile virus outbreaks can be made using surveillance data and a mathematical model representing the interactions between birds, mosquitoes and risk of human spillover. This model system was able to retrospectively forecast mosquito infection rates prior to the week of peak mosquito infection, and to forecast accurately the seasonal total number of human West Nile virus cases prior to when the majority of cases were reported. For this study, we were interested in the data flow process and the question of whether appropriate infrastructure is in place to support real time forecasting. If this forecast system were made operational in real time, public health officials would have an evidence-based decision-support tool to help 1) actively target control of infected mosquito populations (i.e., larviciding and adulticiding), 2) alert the public to future periods of elevated West Nile virus spillover transmission risk, and 3) identify when to intensify blood donor screening.

Author Interviews, Dermatology, Microbiome, Pediatrics, UCSD / 30.04.2019

MedicalResearch.com Interview with: Dr. Jusleen Ahluwalia MD Second-year Dermatology resident University of California, San Diego MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Preadolescence is an interesting stage during which changes in microbial diversity can coincide with the development of acne. This study is the largest assessment of preadolescent acne microbiome in the literature to date. In this study, we found that early acne in preadolescent females is characterized by an abundance of Streptococcus mitis, while later stages are characterized by a predominance of Cutibacterium acnes (formerly known as Propionibacterium acnes).   (more…)
Author Interviews, Biomarkers, Multiple Sclerosis / 30.04.2019

MedicalResearch.com Interview with: Prof. Bernhard Hemmer MD PhD Director of the Neurology Clinic Technische Universität München  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The course of multiple sclerosis (MS) is still highly unpredictable and reliable markers to predict disability progression are largely missing. We found that patients with a high IgG Index, which means that the produce large amount of IgG within the CNS, have a higher risk of disease worsening during the first 4 years. I would consider patients with an elevated IgG index at a higher risk to run a more severe disease course. The marker could be used together with others to guide treatment decisions after multiple sclerosis diagnosis. (more…)
Alzheimer's - Dementia, Author Interviews, End of Life Care, JAMA, University of Pennsylvania / 30.04.2019

MedicalResearch.com Interview with: Emily Largent, PhD, JD, RN Assistant Professor, Medical Ethics and Health Policy Perelman School of Medicine Leonard Davis Institute of Health Economics University of Pennsylvania  MedicalResearch.com: What is the background for this study? What are the main findings?  Response:  Public support for aid in dying in the United States is rapidly growing.  As a result, we’re now seeing debates about whether to expand access to aid-in-dying to new populations – such as people with Alzheimer’s disease – who wouldn’t be eligible under current laws. With those debates in mind, we asked currently healthy people who recently learned about their risk for developing Alzheimer’s disease dementia (i.e., due to the presence of amyloid, an Alzheimer’s disease biomarker) whether they would be interested in aid-in-dying. Our findings suggest that about 20% of individuals with elevated amyloid may be interested in aid-in-dying if they become cognitively impaired.   (more…)
Author Interviews, Cancer Research, Genetic Research, JAMA, Technology / 30.04.2019

MedicalResearch.com Interview with: Steven J.M. Jones, Professor, FRSC, FCAHS Co-Director & Head, Bioinformatics Genome Sciences Centre British Columbia Cancer Research Centre Vancouver, British Columbia, Canada and Jasleen Grewal, BSc.Genome Sciences CentreBritish Columbia Cancer Research CentreVancouver, British Columbia, CanadaJasleen Grewal, BSc. Genome Sciences Centre British Columbia Cancer Research Centre Vancouver, British Columbia, Canada MedicalResearch.com: What is the background for this study? Response: Cancer diagnosis requires manual analysis of tissue appearance, histology, and protein expression. However, there are certain types of cancers, known as cancers of unknown primary, that are difficult to diagnose based purely on their appearance and a small set of proteins. In our precision medicine oncogenomics program, we needed an accurate approach to confirm diagnosis of biopsied samples and determine candidate tumour types for where the primary site of the cancer was uncertain.  We developed a machine learning approach, trained on the gene expression data of over 10,688 individual tumours and healthy tissues, that has been able to achieve this task with high accuracy. Genome sequencing offers a high-resolution view of the biological landscape of cancers. RNA-Seq in particular quantifies how much each gene is expressed in a given sample. In this study, we used the entire transcriptome, spanning 17,688 genes in the human genome, to train a machine learning method for cancer diagnosis. The resultant method, SCOPE, takes in the entire transcriptome and outputs an interpretable confidence score from across a set of 40 different cancer types and 26 healthy tissues.  (more…)
Author Interviews, Cancer Research, JAMA, MD Anderson, Radiation Therapy / 30.04.2019

MedicalResearch.com Interview with: Quynh-Nhu Nguyen, MD Department of Radiation Oncology The University of Texas MD Anderson Cancer Center Houston MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This is the first non-spine bone metastases trial comparing higher dose single fraction radiotherapy vs multifraction standard fractionated radiotherapy for patients with painful bone metastases. The results of this trial demonstrated more durable pain relief and superior local control for patients treated in the higher dose(12 Gy-16 Gy)  single fraction RT compared to standard 30 Gy/10 fractions multifractionated regimen.  This trial supports the previous multiple randomized trials which recommend single fraction should be standard palliative radiotherapy regimen for bone metastases.  This trial is unique in that it addressed previous criticism that single fraction does not provide durable palliation with lower 8 gy single fraction and result in higher re-irradiation rates.  This trial on the contrary with the utilization of modern radiotherapy techniques, demonstrated we can safely and more effectively deliver a higher single fraction radiotherapy regimen for improvement in the quality of life for patients.  This higher dose should be the new standard single fraction regimen for patients who are functional and have a longer life expectancy.  (more…)
Addiction, Author Interviews, Cannabis, Pediatrics, Smoking, Tobacco, Tobacco Research / 30.04.2019

MedicalResearch.com Interview with: Joan S. Tucker, Ph.D. Senior Behavioral Scientist RAND Corporation Santa Monica, CA MedicalResearch.com: What is the background for this study?   Response: In light of young adults’ expanding access to cannabis through legalization for recreational use, there has been growing interest in the co-use of cannabis with tobacco/nicotine products.  Although existing data show that young adults who use cannabis products also tend to use tobacco/nicotine products, little is known about how these products are typically used together. Existing research on co-use has mostly focused on combustible products, not accounting for the recent proliferation in cannabis and tobacco/nicotine product types and methods of use (e.g., vaping). Further, not much is known about whether there are important differences between types of co-use (e.g., using both products on the same occasion, one right after another, but not mixing them vs. using both products by mixing them in the same delivery device) in terms of heaviness of use, consequences from use, or associations with young adult functioning. This study was designed as an important first step toward understanding cannabis and tobacco/nicotine co-use behavior among young adults and addressing these gaps in the research literature. (more…)
Accidents & Violence, Author Interviews, Brain Injury / 29.04.2019

MedicalResearch.com Interview with: Dr. Joseph A Schwartz PhD Public Affairs and Community Service, Criminology and Criminal Justice University of Nebraska Omaha, Omaha, NE  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: My larger research agenda is focused on identifying the ways in which environmental and biological influences work collectively to shape behavioral patterns across major stages of the life course. I am particularly interested in identifying environmental influences that can change biological functioning or activity to result in behavioral change. Brain injury was a natural progression of these interests since brain injury is expected to result in changes in the structure and functioning of the brain, which has been linked to meaningful changes in behavior. There have also been a sizable number of studies that indicate that justice involved populations experience brain injury at a rate that is between five and eight times what is observed in the general population. I was fascinated by this finding and thought that brain injury may be a good candidate influence to investigate further. (more…)

MedicalResearch.com Interview with: Dr. Lu Qi MD PhD Department of Epidemiology, School of Public Health and Tropical Medicine Tulane University New Orleans, LA 70112 Department of Nutrition, Harvard T.H. Chan School of Public Health, Channing Division of Network Medicine, Department of Medicine, Brigham and Women's Hospital and Harvard Medical School Boston, MA 02115 Yoriko Heianza RD, PhD Department of Epidemiology, School of Public Health and Tropical Medicine, Tulane University New Orleans, LA  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Growing data suggest that antibiotic exposure is associated with a long-lasting alteration in gut microbiota, and may be related to subsequent cardiovascular disease (CVD). We investigated associations of duration of antibiotic use in different phases of adulthood (young, middle and late adulthood) with the CVD incidence among women at usual risk. This new analysis from the Nurses’ Health Study shows that women who take antibiotics for long periods, especially during more recent adulthood (such as  in middle- and late adulthood) had a higher risk of CVD in later life.  (more…)
Author Interviews, Global Health, JAMA / 29.04.2019

MedicalResearch.com Interview with: Dr Barbara Mintzes PhD Associate Professor The University of Sydney Charles Perkins Centre and School of Pharmacy Faculty of Medicine and Health The University of Sydney MedicalResearch.com: What is the background for this study?   Response: When medicines are approved for marketing, the information available on rare serious harmful effects, longer-term effects, and outcomes in vulnerable populations is often limited. New serious safety concerns often arise when a medicine is already on the market. In many cases these can be  managed for example through dose reductions or avoiding prescribing to at-risk patients. Drug regulatory agencies such as the US FDA often issue safety warnings to let health professionals and the public know  about new evidence of potential harm and often to provide advice on how to avoid this. We were interested to know how consistent these warnings are between different countries. This is a research project funded by Australia’s National Health and Medical Research Council and the Canadian Institutes of Health Research. We examined warnings for medicines in Australia, Canada the US and the UK over a 10-year period, from 2007 to 2016 inclusive. We were looking at how often regulators issue the same warning if the drug is approved for marketing at the time.  (more…)
Author Interviews, Cancer Research, CMAJ, Emergency Care / 29.04.2019

MedicalResearch.com Interview with: Keerat Grewal, MD, MSc, FRCPC Schwartz/Reisman Emergency Medicine Institute Mount Sinai Hospital Toronto, ON  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Patients with cancer have complex care requirements and often use the emergency department. The purpose of our study was to determine whether continuity of care, cancer expertise, or both, impact outcomes among cancer patients in the emergency setting. Using administrative data we looked at adult patients with cancer who received chemotherapy or radiation therapy in the 30 days prior to an emergency department visit.  (more…)
Author Interviews, Environmental Risks, Heart Disease, JAMA, Toxin Research / 29.04.2019

MedicalResearch.com Interview with: Monica Lind, PhD, Professor, Environmental toxicologist Occupational and Environmental Medicine Uppsala University Hospital Visiting adress: Dag Hammarskjölds väg 60 Uppsala Sweden MedicalResearch.com: What is the background for this study? Response: Previous studies in workers exposed to very high levels of polychlorinated biphenyls (PCBs) have suggested hazardous health effects. However, circulating PCB levels are detected in almost all indivuduals in industrialized countries, but the health effects of moderately elevated levels as seen in the general population are not well established. We investigated levels of PCBs in around 1,000 individuals, all aged 70 years, randomly chosen from the City of Uppsala, Sweden. (more…)

MedicalResearch.com Interview with: Dr Daniel Hwang PhD Postdoctoral Research Fellow The University of Queensland Diamantina Institute MedicalResearch.com: What is the background for this study?   Response: The aim of the this study is to understand the genetic basis of human taste perception. In this international collaboration project, we started by collecting sensory data from twins in the Australia and USA since 2003. Based on the difference in the genetic relatedness between identical and non-identical twins, our previous studies have quantified the amount of genetic influence on sweet taste perception (https://doi.org/10.1017/thg.2015.42) as well as the other sensory phenotypes (https://doi.org/10.1093/chemse/bjs070).  (more…)
Author Interviews, Dental Research, Genetic Research / 28.04.2019

MedicalResearch.com Interview with: Katrina Scurrah PhD Senior Research Fellow (Biostatistician), Twins Research Australia, and Melbourne School of Population and Global Health, The University of Melbourne and Honorary Fellow, Murdoch Childrens Research Institute. MedicalResearch.com: What is the background for this study? Response: Oral health is an important component of general health and yet dental caries (decay) is still common in children (affecting up to one in three 5-6 year old children in Australia). Although we know that some genetic and lifestyle factors (such as diet) are important risk factors for caries, the relative importance of these is still unclear.  Risk factors from pregnancy and very early childhood (even before teeth appear) might also be important. This study is the first to include prospectively measured data on health and well-being from pregnancy, birth and early childhood in a study of twin children. We analysed data from a cohort of 172 pairs of twin children to assess the effects of genes and environment on susceptibility to dental caries at six years-of-age. (more…)
Author Interviews, JAMA, Opiods / 28.04.2019

MedicalResearch.com Interview with: Leah LaRue, PharmD, PMP Associate Director, Clinical Affairs Millennium Health MedicalResearch.com: What is the background for this study? Response: Drug overdose deaths continue to increase, despite the leveling off of prescription opioid use and policy changes limiting opioid prescribing. While fentanyl has garnered most of the attention, overdose deaths involving cocaine and methamphetamine also have increased markedly over the past few years. It is possible that those increases are due not just to those drugs, but to concomitant use with fentanyl. To better understand what is causing this rapid increase in overdose deaths, it is important to characterize the emerging combination of other illicit drugs with fentanyl, which increases the risk of overdose. The purpose of this study was to determine whether rates of the combination of nonprescribed fentanyl with cocaine or methamphetamine have changed in urine drug test (UDT) results through time. (more…)
Author Interviews, Nutrition, Weight Research / 28.04.2019

MedicalResearch.com Interview with: Dale Morrison, PhD School of Exercise and Nutrition Sciences Institute for Physical Activity and Nutrition MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The study was conducted using a model of overfeeding that is likely to be representative of a typical Western overeating diet, high in both carbohydrates and fats; as opposed to a predominantly high-fat diet model that is commonly used in the literature. Our purpose was to examine which tissues are impaired first in response to overeating with a normal dietary composition. We initially hypothesized, based on earlier studies, that the liver would be impaired first by short-term overeating and then skeletal muscle (which soaks up much of the glucose following a meal) would be impaired much later with chronic overeating. However, we didn’t find this. The study found that the body copes with short periods of overeating with additional carbohydrates and makes adjustments by shifting metabolism towards utilizing these excess carbohydrates.  (more…)
Author Interviews, Brigham & Women's - Harvard, JAMA, Pediatrics, Weight Research / 26.04.2019

MedicalResearch.com Interview with: Vincent W. V. Jaddoe, MD, PhD Adjunct Professor of Epidemiology Department of Epidemiology MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Childhood body fat may be affected by patterns of fetal and infant weight change. Children born small for gestational age (SGA) tend to have infant growth acceleration, whereas those born large for gestational age (LGA) tend to have infant growth deceleration. Little is known about fetal and infant growth patterns affecting visceral, liver, and pericardial fat, which are strongly associated with cardiometabolic disease in later life. We assessed in a large population cohort study whether fetal and infant weight change was associated with not only general, but also organ fat at school age. We observed that fetal and infant weight change patterns were both associated with childhood body fat, but weight change patterns in infancy tended to have larger effects. Fetal growth restriction followed by infant growth acceleration was associated with increased visceral and liver fat.  (more…)
Author Interviews, Kidney Disease, Pharmaceutical Companies / 26.04.2019

MedicalResearch.com Interview with: Dr. Jay Venkatesan MD President and CEO of Angion Dr. Venkatesan discusses the recent announcement that ANGION, has received DOD funding for the study of ANG-3070, in treatment of CKD caused by focal segmental glomerulosclerosis,  MedicalResearch.com: What is the background for this announcement? Would you tell us a little about focal segmental glomerulosclerosis (FSGS)? How does ANG-3070 work to prevent kidney scarring? Response: Angion has received a follow-on grant from the Department of Defense (DoD) for $4.76 million in support of the development of ANG-3070, our drug candidate for a form of chronic kidney disease known as focal segmental glomerulosclerosis (FSGS). This funding will allow us to expand our proof-of-concept data for ANG-3070 as a potential anti-fibrotic agent for slowing the progression of FSGS. FSGS is a serious kidney disorder characterized by progressive scarring of the glomeruli, the filtering units of the kidney. There are approximately 80,000 cases of FSGS in the U.S. and Europe, involving both children and young adults. If uncontrolled, FSGS can lead to kidney failure, which may lead to the need for dialysis or a kidney transplant. No therapies exist that treat the underlying cause of FSGS. Therapies such as corticosteroids, immunosuppressants or diuretics  are used, but are mainly supportive and a large proportion of patients progress to end-stage renal disease over a 5-10 year period of time. ANG-3070 is an oral small molecule that selectively inhibits molecular pathways associated with scarring or fibrosis in the kidney and other organs. Our current preclinical study in collaboration with NEPTUNE aims to identify the “signalosome,” or human disease and drug response profile based on the genes, networks and pathways that correlate with the therapeutic activity of ANG-3070 in FSGS. Ultimately, this collaboration will allow us to  develop a precision medicine approach to identify and treat patients in whom ANG-3070 is most likely to block the pathways causing FSGS.  (more…)
