Author Interviews, Circadian Rhythm, Gastrointestinal Disease, Genetic Research, Weight Research / 13.10.2019

MedicalResearch.com Interview with: Marco Colonna, MD Robert Rock Belliveau MD Professor Pathology & Immunology Washington University School of Medicine Qianli Wang MD-PhD Student MSTP student Washington University School of Medicine MedicalResearch.com: What is the background for this study? Response: Many aspects of the mammalian digestive system including gut motility, nutrient absorption, and microbiota follow a daily rhythm. This circadian rhythm is generated by the cyclic expressions of molecular clock genes thought to be present in most cells. Group 3 innate lymphoid cells (ILC3) are lymphocytes residing in the intestinal mucosa that respond rapidly to activation in both homeostatic and inflammatory settings. Namely, ILC3s help maintain the mucosal barrier, regulate epithelial lipid transport, and protect against bacterial enteric infections. As tissue resident cells within the highly dynamic and rhythmic environment of the intestine, it may be advantageous for ILC3s to also be synchronized with the circadian rhythm.  (more…)
Author Interviews, Pulmonary Disease / 13.10.2019

MedicalResearch.com Interview with: Pierre-Régis Burgel MD, PhD Professor of Respiratory Medicine French National Reference Center for Cystic Fibrosis (coordinator) Cochin Hospital and Paris Descartes University Paris, France MedicalResearch.com: What is the background for this study? How does lumacaftor-ivacaftor differ from other treatments for CF?  Response: Cystic fibrosis (CF) is a genetic disease caused by mutations in the gene encoding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein, which acts as a chloride and bicarbonate ion channel across many epithelia. Defective ion transport leads to multiple organ dysfunction, but airway involvement (related to mucus plugging and infection) and malnutrition are among the most important prognostic factors in patients with CF. Over the past decades, symptomatic treatment, including inhaled and systemic antibiotics, nutritional support, pancreatic enzyme replacement, and specialized center care organization have led to major prognostic improvement. More recently, mutation-specific small molecules targeting defective CFTR have been shown to partly restore ion transport in epithelia, which translated into clinical benefits. Phe508del is the most common CFTR mutation with approximately 70% of patients with cystic fibrosis carrying one Phe508del mutation and 40-50% of patients being homozygous for this mutation. Safety and efficacy of lumacaftor-ivacaftor, which partially restores CFTR function, have been reported in phase 3 clinical trials in patients 12 years of age or older who had CF and were homozygous for the Phe508del. Improvement in lung function, reduction in pulmonary exacerbations and a trend towards an increase in body mass index (BMI) led to its approval by the Food and Drug Administration in February 2015 and by the European Medicines Agency in November 2015. However, the magnitude of effect on percent predicted forced expiratory volume in 1 sec (ppFEV1), the small improvement in nutritional status and the limited use of concomitant treatment for reducing exacerbations have cast doubt on the clinical benefits associated with lumacaftor-ivacaftor, which has not been approved in several countries. The present study is a multicenter (n=47 centers) observational post-marketing study aimed at evaluating the effects of lumacaftor-ivacaftor treatment in a real-life setting in France. All patients who initiated lumacaftor-ivacaftor in 2016 in the French cystic fibrosis reference network, which comprises 47 pediatric and/or adult centers, was performed. Our goal was to examine its safety and effectiveness over the first year of treatment in a large, unselected, population of adolescents (≥12 years) and adults (≥18 years) with CF and Phe508del homozygous mutations.  (more…)
Author Interviews, Diabetes, Heart Disease, Infections / 13.10.2019

MedicalResearch.com Interview with: Hean Teik Humphrey Ko PhD candidate School of Pharmacy and Biomedical Sciences Faculty of Health Sciences, Curtin University Perth, Western Australia, Australia MedicalResearch.com: What is the background for this study? Response: Bacterial skin infections consume precious healthcare resources because such infections are common and may sometimes be severe. Statins are relatively affordable and extensively prescribed worldwide to prevent cardiovascular diseases. Additionally, the safety/adverse effects of statins have been well documented. Staphylococcus aureus is a major cause of bacterial skin infections, and statins have been separately reported to exert antibacterial effects against S. aureus, as well as reduce the risk of S. aureus related blood infections. As such, it seemed plausible that statins may prove beneficial in S. aureus related skin infections. However, statins may also induce new-onset diabetes mellitus, a condition which in turn, is a risk factor for skin infections. Therefore, in order to determine if statins could potentially serve as a novel therapeutic agent for skin infections to reduce healthcare costs, this study was conducted to examine the interrelationships between statins, diabetes, and skin infections.  (more…)
Author Interviews, Environmental Risks, Methamphetamine / 11.10.2019

MedicalResearch.com Interview with: Dr Jackie Wright (Fellow ACTRA) Adjunct – Flinders UniversityDirector Environmental Risk Sciences (enRiskS) MedicalResearch.com: What is the background for this study? Response: The contamination of homes with methamphetamine can occur from illegal manufacture or smoking (ice). The methamphetamine residues that are left behind can result in methamphetamine exposures to future occupants of the home, resulting in the potential for adverse health effects. To assess the level of contamination that remains in these homes, the method used is to collect a surface wipe sample. This is a wipe of specified area of a surface (such as walls, floors, kitchen cabinets, or window frames etc) which is then analysed to determine how much methamphetamine residue remain on that surface. The guidelines for determining if a property is safe for occupation is based on surface wipe sampling. This study has further evaluated the level of methamphetamine that is present in a home that was formerly suspected to have been used for the manufacture of methamphetamine. To supplement surface wipe sampling which was undertaken over time, the level of methamphetamine that is within the building/house materials/items themselves was tested, as a bulk analysis, to determine how much methamphetamine is present in these materials, if the methamphetamine has penetrated through and into materials such as the gyprock walls, and if the methamphetamine that is present in materials present when the manufacture occurred have transferred to the homeowners possessions that were brought into the home well after manufacture occurred.  (more…)
Author Interviews, Fertility, Yale / 10.10.2019

MedicalResearch.com Interview with: Emma Xiaolu Zang, Ph.D. Assistant Professor Department of Sociology, Yale University New Haven, CT MedicalResearch.com: What is the background for this study? What are the main findings? Response: In the past decade, Generation Xers—individuals born between the early or mid-1960s and early 1980s—have outnumbered Baby Boomers (i.e. individuals born 1946-64) and currently make up a larger segment of the United States (US) labour force. There is a debate on whether college-educated women in Generation X have spawned a major shift in labor and fertility behaviors compared with their Baby Boomer counterparts because they are less ambitious in balancing family and career and tend to prioritize child-rearing. This study finds some support for this argument. Results reveal that Total Fertility Rates (TFRs) are increasing across cohorts for all educational groups and the increase is greatest for college-educated women. The increase in cohort TFR among college-educated women is being primarily driven by an increasing proportion of those with two children transitioning to a third birth.  (more…)
Author Interviews, Environmental Risks, Global Health, Melanoma / 10.10.2019

MedicalResearch.com Interview with: Suzanne Dobbinson, PhD Senior Research Fellow Centre for Behavioural Research in Cancer Behavioural Science Division Australia MedicalResearch.com: What is the background for this study? Response: Skin cancer prevention programs, such as the SunSmart program in Victoria, have been implemented in Australia over 30 years with the aim of reducing the population’s exposure to ultraviolet radiation (UV), the main cause of skin cancer. A recent reduction in melanoma rates among younger Australians has led to this paper which examines the extent of behaviour change in Melbourne, Australia, and the potential contribution of prevention programs to the decline in melanoma rates. Previous population-based studies assessing the impact of these programs have focused on measuring the change in the prevalence of individual sun protection behaviours, and thus have largely overlooked the use of sun avoidance and composite sun protection behaviours. The focus on tracking individual behaviours may have underestimated the behaviour change associated with these programs. We analysed data from a series of cross-sectional surveys conducted in Melbourne during summer months between 1987 and 2017. These data include the summer before the SunSmart program commenced (1987-88) and across summers in three subsequent decades. (more…)
Alzheimer's - Dementia, Author Interviews, Clots - Coagulation / 09.10.2019

MedicalResearch.com Interview with: Marta Cortes Canteli, PhD Miguel Servet Research Fellow Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) Madrid, Spain MedicalResearch.com: What is the background for this study? Response: Alzheimer´s disease is the most common form of dementia affecting more than 30 million people worldwide. Research in recent years has linked the disease to a reduction in the cerebral circulation; this results in an insufficient supply of nutrients and oxygen to brain cells, leading to their death. Alzheimer disease is also known to be linked to an underlying chronic prothrombotic state. The present study combined physiological and molecular analyses to demonstrate that long-term anticoagulation effectively slows disease progression in a transgenic mouse model of Alzheimer disease.

Author Interviews / 09.10.2019

MedicalResearch.com Interview with: Dr. Aurimas Vyšniauskas PhD Center for Physical Sciences and Technology Vilnius, Lithuania MedicalResearch.com: What is the background for this study? Response: Fluorescent viscosity sensors (also known as molecular rotors) are small molecules that emit light when excited by a laser and the lifetime of their emission is affected by viscosity around the molecule. Higher is the viscosity, longer is the duration of the emission. These molecules are especially useful for sensing viscosity in small biological objects, like a living cell. This is very tricky to do using other methods simply due to a very small size of a cell. Many scientists are interested in the viscosity inside the cell because it tells us how quickly various proteins and other molecules move and reactions in a cell occur. Knowing this information would help us to better understand how various diseases, such as diabetes or Alzheimers, change inner environment of affected cells. (more…)
Annals Internal Medicine, Author Interviews, Outcomes & Safety, Stanford / 08.10.2019

MedicalResearch.com Interview with: Daniel Tawfik, MD, MS Pediatric Critical Care Medicine Stanford University School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Professional burnout is very common among health care providers and is frequently associated with poor quality of care in the published literature. However, we know that reporting biases are common in many fields of literature, and these biases typically result in exaggerated effects being published relative to the true effect. Research on burnout and quality of care appears especially vulnerable, because many studies are not pre-specified or have several potential methods of analysis. If the studies or analyses with more impressive results are more likely to be published, this would result in a skewed picture of the relationship between burnout and quality of care. (more…)
Author Interviews, Cost of Health Care, Health Care Systems, JAMA / 08.10.2019

MedicalResearch.com Interview with: William Shrank, MD, MSHS Chief Medical Officer Humana  MedicalResearch.com: What is the background for this study? Response: Health care waste is a serious problem in the system and the rising and uncontrolled costs of healthcare remain one of the top political and social issues in the U.S. We thought that sufficient time had passed since the 2012 groundbreaking analysis that was developed by Donald M. Berwick, MD, MPP and Andrew D. Hackbarth, MPhil, that first characterized waste in the US health system.  (more…)
Alzheimer's - Dementia, Author Interviews, Mental Health Research / 08.10.2019

MedicalResearch.com Interview with: Marjaana Koponen, PhD Postdoctoral Researcher Kuopio Research Centre of Geriatric Care School of Pharmacy University of Eastern Finland MedicalResearch.com: What is the background for this study? What are the main findings? Response: It is known that antipsychotics are commonly used in the treatment of behavioral and psychological symptoms of dementia, although their use has been linked to serious adverse events. In this study, we found that community dwellers with Alzheimer’s disease who initiated antipsychotic use accumulated more hospital days than non-initiators. This may partially reflect adverse effects and events of antipsychotic use. On the other hand, antipsychotic users accumulated more hospital days due to dementia, mental and behavioral disorders and their caregivers’ days off. Thus, another reason for a higher accumulation of hospital days is care burden and the difficulties in treating the most severe behavioral and psychological symptoms of dementia. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, End of Life Care, Primary Care, Pulmonary Disease, University of Pennsylvania / 07.10.2019

MedicalResearch.com Interview with: Gary Weissman, MD, MSHP Assistant Professor of Medicine Pulmonary, Allergy, and Critical Care Division Palliative and Advanced Illness Research (PAIR) Center University of Pennsylvania Perelman School of Medicine  MedicalResearch.com: What is the background for this study? Response: There are millions of hospitalizations every year in the United States (US) that include a stay in an intensive care unit (ICU). Such ICU stays put strain on health system resources, may be unwanted by patients, and are costly to society. As the population of the US gets older and more medically complex, some have argued that we need more ICU beds and a larger ICU workforce to keep pace. We hypothesized that some proportion of these ICU admissions could be prevented with early and appropriate outpatient care. Such a strategy would alleviate some of the strains and costs associated with ICU stays. If an appreciable proportion of ICU stays were preventable in this way, it would strengthen support for an alternative population-health based framework instead of further investments in the ICU delivery infrastructure.  (more…)
Author Interviews, Dermatology, Environmental Risks, General Medicine, JAMA, Melanoma, Stanford / 07.10.2019

MedicalResearch.com Interview with: Eleni Linos MD MPH DrPH Professor of Dermatology and Epidemiology Stanford University  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: We know that tanning beds are harmful: people who use tanning beds are more likely to get skin cancer. Sexual minority men are much more likely to use tanning beds and also more likely to get skin cancer. In a separate study we discovered that one reason sexual minority men use tanning beds is if it is convenient: e.g. if close to home, cheap, and easy. (https://onlinelibrary.wiley.com/doi/abs/10.1111/bjd.17684). Recent research showed that tobacco retailers cluster in LGB neighborhoods: https://sph.unc.edu/sph-news/more-tobacco-retailers-in-lgbt-neighborhoods-may-explain-smoking-disparities/. This made us wonder if tanning salons also cluster in neighborhoods with more gay men.  (more…)
Author Interviews, Dermatology / 06.10.2019

MedicalResearch.com Interview with: Peter C. Friedman, M.D., Ph.D. Diplomate of the American Academy of Dermatology www.skincenterderm.com MedicalResearch.com: What is the background for this study and case series? Would you describe nonthermal atmospheric pressure plasma? Response: Plasma is essentially ionized gas, the fourth state of matter: molecules or atoms move freely in gas state but in a higher energy state atoms shed electrons and both electrons and ions then move freely and independently. If this material has a temperature close to room temperature, we call it non-thermal atmospheric pressure plasma, or cold plasma. It has been established in countless in vitro and animal experiments that cold plasma has a significant effect on living cells and tissues, for example: selective destruction of cancer cells, helping normal tissue development, inhibiting bacterial, fungal and even viral proliferation. In the handful of clinical trials it could improve wound healing, treat nail fungus. Our group was able to cure precancerous actinic keratosis lesions in a number of patients in a prior study. Based on some of the basic science data regarding the specific molecular and intracellular effects of cold plasma, we theorized that it may be able to cure warts, which are caused by human papilloma virus infection.

Alcohol, Author Interviews, Heart Disease, Pediatrics / 06.10.2019

MedicalResearch.com Interview with: Dr Jiabi Qin, MD, PhD Xiangya School of Public Health Central South University Changsha, China  MedicalResearch.com: What is the background for this study? Response: Congenital heart defects (CHDs), defined as a gross structural abnormality of the heart or intrathoracic great vessels occurring in embryonic period and affected nearly 1% of lives births, is the most common of all congenital defects and remains a major cause of mortality and morbidity in fancy and childhood. With a worldwide prevalence of CHDs now estimated to be 1.35 million newborns with CHDs every year, the number of CHDs is steadily increasing, representing a major global health burden. The association between maternal alcohol exposure and the risk of congenital heart defects (CHDs) has been explored, but little is known about the association between paternal alcohol exposure and the risk of CHDs. Furthermore, subsequent studies regarding the association between alcohol exposure and the risk of congenital heart defects have not yield consistent results. Therefore, given the inconsistency of existing literatures and insufficient evidence of primary studies, further an update meta-analysis based on the new and previously is evidently required. Especially, to our knowledge, any meta-analysis between paternal alcohol exposure and the risk of CHDs have not been conducted.  (more…)
Allergies, Author Interviews, C. difficile, Dental Research, Infections / 05.10.2019

MedicalResearch.com Interview with: Alan E. Gross, PharmD Clinical Assistant Professor University of Illinois Chicago, IL MedicalResearch.com: What is the background for this study? Response: Dentists prescribe 10% of all outpatient antibiotics. Most of this prescribing is for infection prophylaxis prior to dental procedures. Our prior research has found that 80% of prescriptions for dental prophylaxis is unnecessary. Although antibiotic prophylaxis prior to dental procedures is often for a short course (e.g. one time amoxicillin dose), there may be patient harm associated with this. (more…)
Author Interviews, HIV, Infections, STD, UCSD / 05.10.2019

MedicalResearch.com Interview with: Martin Hoenigl, MD Assistant Professor UCSD MedicalResearch.com: What is the background for this study? Response: Technology has changed the way men-who-have-sex-with-men (MSM) seek sex. Over 60% of MSM in the US use the internet and/or smartphone-based geospatial networking apps to find sex partners. Grindr™, a sophisticated geosocial networking app, is the most frequently used dating app among MSM in the United States. Previous research has shown that MSM who use Grindr™ have a greater frequency risky sexual behavior, and more sexual partners, but little is known about the association between Grindr™ use and prevention behavior such as the use of HIV pre-exposure prophylaxis (PrEP). We evaluated risk behavior, PrEP use, and Grindr™ usage among MSM receiving community-based HIV and bacterial sexually transmitted infection (STI) screening in central San Diego. Participants who tested negative for HIV and who were not on PrEP were offered immediate PrEP.  (more…)
Author Interviews, Cannabis, JAMA / 05.10.2019

MedicalResearch.com Interview with: Hongying (Daisy) Dai, PhD Associate Professor Department of Biostatistics | College of Public Health University of Nebraska Medical Center  MedicalResearch.com: What is the background for this study? Response: Although marijuana is still classified as a Schedule I drug at the Federal level, as of June 2019, 33 states and the District of Columbia have legalized one or more forms of marijuana; 11 states and the District of Columbia have approved both medical and recreational uses. Public opinion on marijuana has changed dramatically over the last two decades and support for legalization has doubled since 2010. However, very little is known about the prevalence and patterns of marijuana use among adults with medical conditions. This study analyzed the 2016 and 2017 Behavioral Risk Factor Surveillance System data to report the prevalence and patterns of marijuana use among adults with self-reported medical conditions.  (more…)
Author Interviews, Memory / 04.10.2019

MedicalResearch.com Interview with: Noah Forrin, PhD Postdoctoral fellow in Psychology University of Waterloo  MedicalResearch.com: What is the background for this study? Response: Everyday experience suggests that people have poor memory for information that they encounter prior to their own public performance.  For example, prior to giving a presentation at school or at work, people often struggle to remember information from a presentation that occurred before their own. n our study, we tested the hypothesis that performance anticipation reduces memory for pre-performance information.  We found that when participants anticipated a simple upcoming presentation--reading words out loud in front of someone else--their memory was diminished prior to reading those words out loud.  Memory may be reduced in this way because people are thinking about their upcoming performance or because they are anxious (i.e., performance anxiety). (more…)

MedicalResearch.com Interview with: Daniel C. Payne, PhD, MSPH Senior Scientific Advisor Viral Gastroenteritis Branch US Centers for Disease Control and Prevention  MedicalResearch.com: What is the background for this study? Response: Rotavirus vaccines have been recommended for US infants for more than 10 years.  This study used seven years of active surveillance data from seven hospitals around the US to evaluate the effectiveness of rotavirus vaccines in the US.  (more…)
Author Interviews, Cancer Research, Genetic Research / 04.10.2019

MedicalResearch.com Interview with: Dr Ranjit Manchanda MD, MRCOG, PhD Professor & Consultant Gynaecological Oncologist NHS Innovation Accelerator (NIA) Fellow Integrated Academic Training Programme Director London Specialty School of Obstetrics & Gynaecology, Health Education England Cancer Research UK, Barts Centre | Queen Mary University of London Department of Gynaecological Oncology | Barts Health NHS Trust, Royal London Hospital London  MedicalResearch.com: What is the background for this study? Response: Current national and international guidelines recommend genetic-testing (for BRCA genes) in women with breast cancer (BC) who fulfil recognised/established clinical criteria which are based on a history of cancer in the patient and family. However 50% of BRCA carriers do not fulfil these criteria. Thus the current  family-history or clinical-criteria based approach misses half the people at risk. Additionally only 20%-30% of patients eligible tend to get referred for and access BRCA testing. Newer genes like PALB2 which cause breast cancer have been identified and can also be tested for. Knowing a patient’s mutation status (carrier identification) can have a number of benefits. After unilateral breast cancer, mutations carriers can choose contralateral prophylactic-mastectomy (CPM) or preventative mastectomy of the second breast to reduce their risk of developing contralateral breast cancer. Additionally they can opt for surgical prevention for ovarian-cancer (OC). Cancer affected carriers may become eligible for novel drugs (like poly-adenosine-diphosphate-ribose-polymerase (PARP) inhibitors) and other precision-medicine based novel drug therapies through clinical trials. A major advantage of genetic-testing is enabling testing relatives of breast cancer mutation carriers, to identify unaffected relatives carrying mutations who can benefit from early diagnosis and cancer prevention. Testing everyone instead of being restricted by family history will identify many more mutation carriers and their family members who can benefit from precision prevention. A large proportion of these cancers are preventable in known unaffected mutations carriers. (more…)
Antibiotic Resistance, Author Interviews, Cancer Research, Genetic Research, Journal Clinical Oncology, University Texas / 03.10.2019

MedicalResearch.com Interview with: Fangjian Guo, MD, PhD Department of Obstetrics and Gynecology Center for Interdisciplinary Research in Women’s Health University of Texas Medical Branch Galveston TX  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The identification of BRCA1/BRCA2 pathogenic variants in women susceptible to breast or ovarian cancer in the 1990s created an opportunity for targeted, individualized cancer prevention. BRCA testing in young women before cancer onset enables early detection of those with increased cancer risk and creates an opportunity to offer life-saving prophylactic procedures and medication. We used insurance claims data to assess the use of BRCA testing in unaffected young women <40 years of age between 2006 and 2017 and found that BRCA testing among cancer-free women under 40 has more than doubled in recent years. However, only about 25% of all BRCA testing done in 2017 was performed in unaffected young women under 40. (more…)

Dr. Dario Altieri in his lab with Dr. Ekta Agarwal conducting an experimentMedicalResearch.com Interview with: Ekta Agarwal, Ph.D. Postdoctoral fellow in the lab of Dario Altieri, M.D. Wistar president and CEO ,Director of the Institute’s Cancer Center Robert & Penny Fox Distinguished Professor and co-first author on the study. MedicalResearch.com: What is the background for this study?   Response: Mitochondrial reprogramming is one of the hallmarks of cancer cell growth and metastasis. There are several studies correlating mitochondrial dynamics to increased cancer cell motility and invasion. However, therapies that can target molecular markers associated with mitochondrial functions and integrity are still obscure. Thus, it is crucial to identify novel targets and pathways that regulate mitochondrial functions in cancer. This study reveals one such mitochondrial molecular pathway which might serve as an actionable anti-cancer therapy. (more…)

MedicalResearch.com Interview with: Tiffany G. Munzer, MD Department of Pediatrics University of Michigan Medical School Ann Arbor  MedicalResearch.com: What is the background for this study? Response: There’s been such a rise in the prevalence of tablet devices and the recommendation for families of young children has been to engage in media together because children learn the most from screens when they’re shared with an adult. However, little is known about how toddlers and adults might behave and interact using a tablet. (more…)

MedicalResearch.com Interview with: Andrew Sumarsono, MD UT Southwestern Medical Center MedicalResearch.com: What is the background for this study?   Response: There are currently 12 types of medications used to treat type 2 diabetes. With approximately 30 million adults living with diabetes in the United States, the rising cost of insulin has raised concerns about the affordability of diabetes care. We evaluated trends in total spending and number of prescriptions of all diabetes therapies among Medicare Part D beneficiaries between 2012 and 2017. (more…)
Author Interviews, ENT, Genetic Research, Pediatrics / 02.10.2019

MedicalResearch.com Interview with: Manvendra K Singh PhD Program in Cardiovascular and Metabolic Disorders, Duke-NUS Medical School National Heart Research Institute, National Heart Center Singapore, Singapore MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Craniofacial and cardiovascular abnormalities are the most common defects, contributing to more than one-third of the congenital diseases. Proper formation of these structures involves intricate processes such as proliferation, migration, and differentiation of neural crest cells (NCCs). Functional defects in NCCs result in craniofacial malformations, including cleft lip and/or cleft palate. Many transcription factors, chromatin remodelling factors, non-coding RNA and signalling molecules have been implicated in impaired neural crest development that result in cardio-craniofacial syndromes. However, the cell-autonomous role of splicing regulators in neural crest biology remains unclear and warrants further investigation. (more…)

MedicalResearch.com Interview with: Melissa A. Simon, M.D., M.P.H. Member, U.S. Preventive Services Task Force George H. Gardner professor of clinical gynecology, Vice chair of clinical research Department of Obstetrics and Gynecology Professor of preventive medicine and medical social sciences Northwestern University Feinberg School of Medicine  MedicalResearch.com: What is the background for this study? Response: Asymptomatic bacteriuria, or ASB, is when someone has bacteria in their urine but does not have any signs or symptoms of a urinary tract infection. For pregnant people, this can be a major health concern resulting in severe, even life-threatening, infections that can lead to serious harms for both the mother and the baby. The Task Force’s primary finding in updating its recommendation on this topic was that screening for ASB continues to be beneficial in preventing complications and preserving the health of mothers and their babies during pregnancy.  (more…)
