MedicalResearch.com: What is the background for this study? Response: E-cigarettes were introduced first in US market as a less harmful method of nicotine delivery which potentially would help smokers to have a less harmful option. However, overtime e-cigarette found its niche of consumers in the younger/tobacco naïve population. Our study is amongst the first studies that describes those who use e-cigarette without any history of combustible-cigarette smoking.  (more…)
Alzheimer's - Dementia, Author Interviews, Critical Care - Intensive Care - ICUs, Geriatrics, Inflammation, Johns Hopkins / 11.10.2018

MedicalResearch.com Interview with: Keenan Walker, PhD Johns Hopkins University School of Medicine Baltimore MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study was conducted in response to anecdotal accounts and scientific evidence which suggests that major medical conditions, such as critical illness and severe infections, can have a long-term neurological effect on some individuals. There are quite a few studies to date which have found that critical illnesses, such as severe sepsis, are associated with long-term cognitive impairment. Based on this evidence, we wanted to figure out to what degree critical illness and major infection may affect later brain structure and to determine whether the structural changes associated with these events were similar to those observed in Alzheimer’s disease. Our main finding was that individuals who had one or more critical illness or major infection major infection during the decades leading up to older adulthood were more likely to have smaller brain volumes in brain regions most vulnerable to Alzheimer's disease.

MedicalResearch.com Interview with: Nathaniel Ernstoff, MD University of Miami MedicalResearch.com: What is the background for this study? What are the main findings? Response: Despite the best efforts of all healthcare providers, colon cancer screening is underutilized with screening rates ranging anywhere from 58-76% based on the state (American Cancer Society 2017). At best we are still failing to screen 25% of the population.  Patients have serious concerns about colorectal cancer (CRC) screening with the most common barriers to screening being fear of colonoscopy and of the bowel preparation, amongst others. These barriers coupled with the lack of understanding of the risks, benefits, and the efficacy of screening contribute to our inadequate screening. This study aims to prove that through education, and most importantly comprehension, patients will choose one of the 6 recommended colorectal cancer screening tests that best fits their preferences. In this study we had 24 patients who previously refused colonoscopy on 3 separate occasions, and had no other CRC screening, undergo a virtual reality (VR) demonstration, created by TheBodyVR, to see if education would improve the uptake of screening. Prior to the virtual reality demonstration, the patients completed a 5-item questionnaire which evaluated their baseline knowledge of CRC risk, polyps and screening as well as determining barriers to prior screening. The patient then viewed the VR demonstration which starts with an overview of colorectal cancer, followed by a tour through a virtual colon explaining and showing the viewer polyps and cancer. Finally, the demonstration reviews and compares the strengths and weaknesses of all USPSTF-recommended CRC screening tests.  After the study, the patients complete the same questionnaire, and in this study there was a statistically significant improvement in knowledge in all questions.  Ultimately, 23 of 24 patients who previously refused colorectal cancer screening on 3 separate occasions chose to undergo screening after the VR demonstration, and about 50% have performed the screening 60 days out from the study's completion.

Author Interviews, Cancer Research, Colon Cancer, Genetic Research, University Texas / 10.10.2018

MedicalResearch.com Interview with: Mohammad Bilal, MD University of Texas Medical Branch MedicalResearch.com: What is the background for this study? Response: Colorectal cancer (CRC) is the fourth most commonly diagnosed cancer among adults in the United States and the second leading cause of cancer related deaths. Recent studies have shown an increasing incidence of CRC in younger patients. This has led to increasing interests in identifying patient populations who might be at increased risk of developing CRC. The U.S. Multi-Society Task Force of Colorectal Cancer (MSTF) recommends that CRC screening should begin at age 50 in average-risk persons. However, recently the American Cancer Society (ACS) have published recommendations to begin CRC screening at age 45 years in average risk patient population. These recommendations were primarily based of modeling studies since there is little outcomes data in younger age groups in regards to prevention and detection of CRC. Despite these new recommendations from the ACS, there is limited direct evidence to support CRC screening at a younger age. In our study, we have evaluated the predictors of increased prevalence of adenomas in the 40 to 49-year-old individuals undergoing colonoscopy.  (more…)
Author Interviews, Cannabis, Gastrointestinal Disease / 10.10.2018

MedicalResearch.com Interview with: Tarek Alansari, MD Metropolitan HospitalTarek Alansari, MD Metropolitan Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cannabis is the most frequently consumed recreational drug in the world. The use of cannabis is becoming increasingly accepted by the general public in the United States. The estimates of the prevalence of cannabis use in the United States is about 9.5% in the adult population and the prevalence of dependence or abuse approaches 2.9%. Those under the age of 35 years are the most frequent consumers. According to Business Insider as of June 2018, recreational cannabis is legal in 9 states and medical cannabis is legal in 30 states. Recent surveys show that about 35 million Americans are frequent cannabis users. Aiming for symptomatic relief, some patients with different gastrointestinal disorders have turned to cannabis without fully understanding the effect of its use for their individual condition. Biliary tract disease, ethanol abuse, infections, autoimmunity, and genetics are well known causes of acute pancreatitis. However, medication-induced pancreatitis remains a less common etiology. In about 20% of cases of acute pancreatitis despite of the great improvement in genetic testing and imaging modalities, the workup still fails to reveal an etiology. These cases are labeled idiopathic. Cannabis use is emerging as a rare, possibly overlooked cause of acute pancreatitis with few cases reported in the literature. In the United States, only 5 cases of cannabis - induced acute pancreatitis (AP) have been reported till September 2017. The review of literature revealed that only 26 cases of cannabis-induced AP have been reported worldwide. (more…)

What are the main findings? Response: The choice of correct individualized therapy for breast cancer depends on correct diagnosis: receptors for estrogen, progesterone and HER2 are determined routinely. However 5-10% of these routine diagnostics are inaccurate and may entail suboptimal therapy. We have paved the way for additional diagnostics from gene expression data so as to increase precision of diagnostics. (more…)
Author Interviews, Cancer Research, Exercise - Fitness / 10.10.2018

MedicalResearch.com Interview with: Laurien Buffart, PhD Chair Amsterdam eXercise in Oncology (AXiON) research Departments of Epidemiology & Biostatistics and Medical Oncology VUmc  Amsterdam | The Netherlands MedicalResearch.com: What is the background for this study? What are the main findings?  Response: There is evidence from randomized controlled trials that exercise has beneficial effects on physical fitness, fatigue, quality of life and self-reported physical function during and following cancer treatment. The magnitude of the effects, however, often appear modest, possibly because interventions rarely target patients with worse symptoms and quality of life. Based on individual patient data from 34 randomized controlled trials, we found that exercise interventions during cancer treatment are effective in maintaining muscle strength and quality of life, regardless of their baseline values. Offering exercise interventions post cancer treatment to patients with a relatively high muscle strength and quality of life does not appear to further improve these outcomes. For aerobic fitness, exercise interventions during treatment had larger effects in patients with higher baseline aerobic fitness, whereas all patients were able to improve aerobic fitness post treatment. Greater effects on fatigue and self-reported physical function were found for patients with worse baseline fatigue and physical function, both during and post-treatment.  (more…)
Author Interviews, Gastrointestinal Disease, NYU, Surgical Research, Weight Research / 10.10.2018

MedicalResearch.com Interview with: Violeta Popov, MD PhD FACG Assistant Professor of Medicine Director of Bariatric Endoscopy, NY VA Harbor Healthcare(Manhattan) Division of Gastroenterology NYU Langone Medical Center  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Bariatric surgery is the most effective method currently available for durable weight loss. In the first few months after surgery, patients typically experience significant weight loss. Rapid weight reduction though can lead to the development of gallstones and biliary disease, described in up to 40% of post-bariatric patients. To avoid these complications, the gallbladder was removed during open bariatric procedures in the past. However, with the advent of laparoscopic surgery, concomitant cholecystectomy with bariatric surgery is no longer performed for many reasons.  The aim of is study is to assess if biliary diseases such as acute pancreatitis, acute cholecystitis, acute cholangitis, and cholecystectomy have increased with this change in practice. This is a retrospective cohort analysis of the National Inpatient Sample (NIS), the largest publicly available inpatient database in the United States of nonfederal institutions, with approximately 1000 hospitals participating and information on over 7 million inpatient admissions. We found that from 2006 to 2014 there has been an approximately 10-fold increase in hospital admissions for biliary diseases, as well as similar increase in cholecystectomies, in patients who have a history of bariatric surgery. There was no significant change in admissions in patients without bariatric surgery between 2006 and 2014 admitted for the same biliary diseases.  (more…)
AHRQ, Author Interviews, Cost of Health Care, JAMA / 09.10.2018

MedicalResearch.com Interview with: Salam Abdus, PhD Division of Research and Modeling, Center for Financing, Access, and Cost Trends, Agency for Healthcare Research and Quality Department of Health and Human Services Rockville, Maryland MedicalResearch.com: What is the background for this study? What are the main findings?  Response: High deductible health plans are more prevalent than ever. Previous research showed that adults in low-income families or with chronic conditions are more likely to face high financial burdens when they are enrolled in high-deductible health plans, compared to adults in higher income families or healthier adults. In this study we examined the financial burden of high-deductible health plans among adults who are both low income and chronically ill. We used AHRQ’s Medical Expenditure Panel Survey Household Component (MEPS-HC) data from 2011 to 2015 to study the prevalence of high out-of-pocket health care spending burden of high deductible health plans among adults enrolled in employer-sponsored insurance. We included family out-of-pocket spending on premiums and health care services. We found that among adults who had family income below 250% of Federal Poverty Level (FPL), had multiple chronic conditions, and were enrolled in high-deductible health plans, almost half (46.9%) had financial family out-of-pocket health care burden exceeding 20 percent of family disposable income.

MedicalResearch.com Interview with: Thomas P. Lodise Jr., PharmD, PhD Clinical Pharmacist at the Stratton VA Medical Center in Albany, NY Albany College of Pharmacy and Health Sciences Albany, NY MedicalResearch.com: What is the background for this study? How does Ceftolozane/Tazobactam differ from other antibiotics for serious Gram-negative infections including Pseudomonas aeruginosa? Response: Treatment of patients with Gram-negative infections is increasingly difficult due to rising resistance to commonly used agents. Ceftolozane/tazobactam (C/T) is a potent anti-pseudomonal agent with broad Gram-negative coverage that is indicated for complicated urinary tract infections (cUTI) and complicated intra-abdominal infections (cIAI) and is currently being studied for ventilated nosocomial pneumonia. C/T differs from other antibiotics in terms of its potency against multi-drug resistant Pseudomonas aeruginosa, one of the most concerning and difficult-to-treat Gram-negative pathogens. This study evaluates C/T in a large database of US hospitals to better understand treatment patterns and associated outcomes. (more…)

MedicalResearch.com Interview with: Andrei V. Tkatchenko, M.D., Ph.D. Associate Professor Columbia University Medical Center Edward S. Harkness Eye Institute New York, NY 10032 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Clear distance vision is rapidly becoming a rare privilege around the world, especially in Asia, due to increasing prevalence of myopia. Although much effort has been directed towards elucidating the mechanisms underlying refractive eye development and myopia, treatment options for myopia are mostly limited to optical correction, which does not prevent progression of myopia or pathological blinding complications often associated with the disease. During early childhood development, the axial length of the eye normally grows to match its optical power in a process called emmetropization, producing focused images on the retina. However, very often environmental and genetic factors lead to a mismatch between the optical power of the eye and its axial length resulting in the development of myopia if eyes grow too long for their optical power. Experimental studies in many animal species suggest that emmetropization is regulated by optical defocus. The eye can compensate for imposed negative and positive optical defocus by increasing or decreasing its growth rate, respectively. However, the molecular mechanisms underlying emmetropization are poorly understood which prevents development of anti-myopia drugs. (more…)

MedicalResearch.com Interview with: foamixDavid Domzalski CEO Foamix Pharmaceuticals MedicalResearch.com: What is the background for this study?  How does FMX101 differ from other treatment for acne, ie benzoyl peroxide, topical clindamycin etc?  Response: This study measures the safety and efficacy of a topical foam formulation of the antibiotic minocycline, for the treatment of moderate-to-severe acne. Minocycline is one of the most commonly used products for the treatment of acne, but is currently only available in an oral dosage form. Significant side effects are associated with oral minocycline, including GI upset, photosensitivity, headaches, dizziness, and other potential effects on the CNS.  In addition to the side effects associated with oral minocycline, many currently available topical acne medications contain ingredients which can be drying and irritating to the skin.  These side effects can be frustrating to patients and potentially impact overall compliance to their treatment regimen.  The study addresses important unmet needs in dermatology to determine whether providing patients with a topical dosage form of minocycline may have potential advantages over existing products. In our first two Phase 3 clinical studies, >95% of facial local tolerability signs and symptoms were classified as “none” or “mild,” including dryness, erythema and itching.  Also, our topical minocycline foam, FMX101, is a natural triglyceride-based vehicle that does not contain ingredients that serve as  primary irritants or surfactants.  We believe that FMX101, if approved, would be the first topical minocycline available for the treatment of acne and provide a novel and much needed treatment option for patients who suffer from the physical and psycho-social effects of acne.

MedicalResearch.com Interview with: "MaxMedica D-vitamin" by Midsona Sverige AB is licensed under CC BY 2.0Dr Mark J Bolland PhD Bone and Joint Research Group Department of Medicine University of Auckland New Zealand MedicalResearch.com: What is the background for this study? Response: Vitamin D supplements have long been recommended for older people to treat or prevent osteoporosis. Early evidence suggested vitamin D supplements might have benefits for musculoskeletal health, but more recent systematic reviews have reported no effect of vitamin D supplementation on fractures, falls or bone mineral density. Some authors have suggested that inadequate vitamin D doses might explain these null results. (more…)
Author Interviews, HIV, HPV, PLoS, Sexual Health / 09.10.2018

MedicalResearch.com Interview with: Brandon Brown, MPH, PhD Associate Professor Center for Healthy Communities Department of Social Medicine, Population and Public Health UCR School of Medicine Riverside, CA MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The authors have been working in Lima, Peru on HIV-related projects for over 17 years. This particular study arose out of interest from our main community collaborator and the only gay men’s health NGO in Lima, Epicentro Salud (http://epicentro.org.pe/index.php/en/). The NGO noticed that one of the main health issues among their clients was genital warts. When we learned this, we applied for funding through the Merck Investigator Initiated Studies Program to conduct a study examining the link between genital warts and incident HIV infection. Although most studies have shown a general link between HPV and HIV co-infection, our findings illustrate the strong relationship between individual HPV types and HIV infection. Specifically, individuals in our study with any HPV type, more than one HPV type, or high-risk HPV were more likely to acquire HIV. (more…)

MedicalResearch.com Interview with: David G. Thanassi, Ph.D. Professor and Interim Chair Department of Molecular Genetics & Microbiology Center for Infectious Diseases Stony Brook University Stony Brook, NY 11794-5222 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Pathogenic bacteria such as Escherichia coli use hair-like surface appendages termed pili to colonize tissues within the host and initiate infection.  Together with our collaborators - the group of Huilin Li at the Van Andel Research Institute - we used an advanced imaging technique termed cryo-electron microscopy to determine snapshots of bacterial pili as they are being assembled.  The pili we studied are critical for uropathogenic strains of E. coli to colonize the urinary tract and cause urinary tract infections.  Our work revealed a new stage in the pilus assembly process and new details about how these structures are built on the bacterial surface.   (more…)
Abbott, Author Interviews, Flu - Influenza / 08.10.2018

MedicalResearch.com Interview with: Dr. Norman Moore PhD Abbott’s Director of Scientific Affairs for Infectious Diseases  MedicalResearch.com: What is the background for this test? How does ID NOW differ from other tests for influenza? Response: This test was developed to give providers – and their patients – lab-accurate results more quickly than ever, right at the point of care. It was designed for ease of use, as well as to be portable and small enough that it can be used in a broad range of healthcare settings, including walk-in clinics, urgent care centers, doctors’ offices and emergency rooms. Prior to ID NOW, traditional molecular tests offered great performance, but took too long to impact treatment decisions. ID NOW is able to deliver the performance and accuracy of lab-based tests in a timeframe that offers the best chance of improving treatment decisions.  (more…)

MedicalResearch.com Interview with: Kandice A. Kapinos, Ph.D. Economist Professor RAND Corporation Pardee RAND Graduate School  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: The economic burden of osteoporotic fractures is substantial with studies estimating the annual healthcare cost burden between $10 to 17 billion. Although estimates from individual studies vary, most studies assessing costs after a fracture only explore up to twelve months following a fracture. There is little investigation of how fracture patients’ costs evolve over a longer post-fracture period. As osteoporotic fractures are one of the most common causes of disability among older adults and can translate into greater medical costs, we focused on studying Medicare beneficiaries. In fact, previous research has suggested that most of the increase in Medicare spending over time can be explained from costs associated with treating higher risk Medicare beneficiaries. Our objective in this study was to compare health care costs over a 3-year period of those who experienced a fracture to those who did not among a sample of Medicare beneficiaries who were at an increased risk of having a fracture. Consistent with previous studies, we found a significant increase in expenditures in the year immediately following a fracture relative to controls: almost $14,000 higher for fractures relative to controls. However, at 2 and 3-years post-fracture, there were no significant differences in the change in expenditures between fracture cases and controls. We note that these findings may be different for beneficiaries living in skilled nursing facilities or other non-community-based settings. (more…)

MedicalResearch.com Interview with: Rowan Chlebowski, MD, PhD Research Professor Department of Medical Oncology & Therapeutics Research City of Hope National Medical Center Duarte, California MedicalResearch.com: What is the background for this study? Response: Regarding study background while obesity has been for several decades been well established respect cancer incidence, it has been difficult to provide evidence that weight loss in postmenopausal women would reduce their breast cancer risk. We address this question by examining short-term, three year weight loss of 5% or more in most menopausal women participating in the Women's Health Initiative observational study. Women who lost this moderate amount of weight regardless of their baseline weight experience as statistically significant lower breast cancer incidence. (more…)

MedicalResearch.com Interview with: "Plugged into dialysis" by Dan is licensed under CC BY 2.0 Elani Streja MPH PhD Division of Nephrology and Hypertension University of California, Irvine | UCI · Elvira O. Gosmanova, MD, FASN Medicine/Nephrology Albany Stratton VA Medical Center Csaba P Kovesdy MD Fred Hatch Professor of Medicine Division of Nephrology, University of Tennessee Health Science Center Nephrology Section Chief, Memphis VA Medical Center Director, Clinical Outcomes and Clinical Trials Program Memphis TN, 38163  MedicalResearch.com: What is the background for this study? What are the main findings? Response:  Cardiovascular disease (CVD) is one of the leading causes of mortality and morbidity in patients with chronic kidney disease (CKD). Statins are lipid-lowering drugs that have a proven track record in reducing risk of CVD in patients with advanced CKD who did not yet reach its terminal stage or end-stage renal disease (ESRD). Paradoxically, new prescription of statins after ESRD onset failed to reduce CVD related outcomes in three large clinical trials. However, benefits of statin continuation at transition from advanced CKD to ESRD was never formally tested. Therefore, we identified a cohort of 14,298 US Veterans who used statins for at least half of the year during 1 year before ESRD transition and evaluated mortality outcomes based on whether statins were continued or stopped after ESRD onset. We found that ESRD patients who continue statins for at least 6 months after transition had 28% and 18% lower risk of death from any cause or cardiovascular causes, respectively, during 12-months of follow up, as compared with statin discontinuers.

Author Interviews, C. difficile, Critical Care - Intensive Care - ICUs, Infections / 07.10.2018

MedicalResearch.com Interview with: Richard Hengel, MD, FRCPC, FACP Atlanta ID Group Richard Hengel, MD, FRCPC, FACP Atlanta ID Group MedicalResearch.com: What is the background for this study? How does Bezlotoxumab differ from other medications for recurrent C. difficile infections? Response: Clostridium difficile infection (CDI) is now the most common hospital acquired infection in the United States, accounting for significant morbidity and mortality, not only in the US, but around the world. Despite standard antibiotic therapy targeting the Clostridium difficile bacterium directly, recurrent infection is common, occurring in a quarter to a third of patients, often frail individuals with other concurrent medical problems. These patients can have multiple recurrences leading to their progressive deterioration over time. Until recently, the only treatment for CDI included antibiotics. More recently, fecal microbiota transplant is a promising, but as yet, FDA unapproved therapy. Bezlotoximab is a new FDA approved treatment for recurrent Clostridium difficile infection (rCDI) that compliments standard antibiotics. Bezlotoxumab is a monoclonal antibody targeting toxin B produced by Clostridium difficile during CDI. In two large treatment trials, bezotoxumab, in addition to standard-of-care antibiotics, reduced the frequency of CDI recurrences from about 28% to about 18%. In this study, we set out to see if this new drug performed as well in actual clinical practice as it did in the published clinical trials. (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, Hospital Acquired, Infections, Kidney Disease, Merck / 06.10.2018

MedicalResearch.com Interview with: Michelle Hoffman Brown Associate Principal Scientist Merck MedicalResearch.com: What is the background for this study? What are the kidney risks of using colistin to treat carbapenem-resistant bacterial infections? Response: Gram-negative pathogens are responsible for half of all healthcare-associated infections and their ability to resist traditional antibiotics makes them more dangerous for seriously ill patients in a healthcare setting. The need for new approaches to treat these pathogens is essential and this trial aimed to evaluate the efficacy and safety of imipenem/relebactam (IMI/REL) for the treatment of these challenging infections. Nephrotoxicity is a common complication of colistin-based therapy and is the potential adverse experience of greatest concern to prescribing clinicians, limiting its use to treat carbapenem-resistant bacterial infections. Relebactam is a novel β-lactamase inhibitor that restores imipenem activity against many imipenem-non-susceptible strains of Gram-negative pathogens. In the Phase 3 RESTORE-IMI 1 study (NCT02452047), IMI/REL was shown to be as effective as, but better tolerated than, colistin plus imipenem, including as demonstrated by a lower incidence of treatment-emergent nephrotoxicity (prespecified secondary endpoint). This analysis looked at additional renal safety data from the RESTORE-IMI 1 trial.  (more…)
Author Interviews / 06.10.2018

MedicalResearch.com Interview with: MedicalResearch.com Interview with: Gili Regev-Yochay, MD, Lead author Director of the Infection Prevention & Control Unit Sheba Medical Center Tel HaShomer, Israel.  MedicalResearch.com: What is the background for this study? Response: CPE (Carbapenemase producing Enterobacteriaceae) is endemic in Israel. In our ICU we had a prolonged CPE outbreak with one particular bacteria, which is not that common (OXA-48 producing-Serratia marcescens).  Enhancing our regular control measures (hand hygiene, increased cleaning etc..) did not contain the outbreak. MedicalResearch.com: What are the main findings?  Response: The outbreak source were the sink-traps in nearly all the patient rooms, which were contaminated with this same bacteria. Once we understood that this was the source we took two measures: 1) Sink decontamination efforts, including intensive chlorine washes of the drainage and water system, replacement of all sink-traps, acetic acid treatment and more, all these efforts were only partially and only temporarily successful. So that even today, after a year of such efforts and a period in which we didn't have any patients with this infection, the drainage system is still contaminated with these bugs and they grow in the sink-traps and can be found in the sink outlets. 2) The second measure we took was an educational intervention, where we engaged the ICU team through workshops to the issue of the contaminated sinks and together enforced strict "sink-use guidelines" (sinks are to be used ONLY for hand washing, prohibiting placement of any materials near the sinks, etc.). Using these two measure the outbreak was fully contained. To date, nearly 1.5 years since the last outbreak case, we did not have any further infections in our ICU patients with this bug. MedicalResearch.com: What should readers take away from your report? Response: Sink-traps and drainage systems can be a major source of CPE transmission. While traditionally CPE outbreaks were attributed to patient-to patient transmission, the environment and particularly water and drainage system appears to play a major role. MedicalResearch.com: What recommendations do you have for future research as a result of this work?  Response: There is urgent need to find a technological solution for drainage system contaminations. While some have suggested to get rid of sinks in ICU this is probably not realistic in the era of emerging Clostridium infections (where washing hands, and not only alcohol rubs are needed).  Citation: Gili Regev-Yochay, Gill Smollan, Ilana Tal, Nani Pinas Zade, Yael Haviv, Valery Nudelman, Ohad Gal-Mor, Hanaa Jaber, Eyal Zimlichman, Nati Keller, Galia Rahav. Sink traps as the source of transmission of OXA-48–producing Serratia marcescens in an intensive care unit. Infection Control & Hospital Epidemiology, 2018; 1 DOI: 1017/ice.2018.235 [wysija_form id="3"] [last-modified]     The information on MedicalResearch.com is provided for educational purposes only, and is in no way intended to diagnose, cure, or treat any medical or other condition.

MedicalResearch.com Interview with: Claudia Syueping Crowell, MD Lead author of the study Assistant professor of pediatrics University of Washington and Seattle Children's Hospital MedicalResearch.com: What is the background for this study? What are the main findings?
  • This research was conducted as part of the SMARTT (Surveillance Monitoring for ART Toxicities) study, which is an observational cohort study of HIV exposed uninfected children with the overall aim of studying the long-term safety of fetal and infant exposure to prophylactic antiretroviral (ARV) therapy.
  • This particular analysis was conducted in response to prior studies that showed an increased risk of seizures and other neurologic conditions in children who were exposed to ARVs in utero.
  • The aim of our study was to determine if in utero exposure to any particular ARV is associated with the diagnosis of neurologic conditions later in infancy and childhood.
  • In our cohort of 3747 HIV-exposed uninfected children we found 237 children who had neurologic conditions, 16 of whom were exposed to efavirenz in utero and 4 of whom were exposed to dolutegravir in utero.
  • The most common neurologic diagnoses were microcephaly, febrile seizures, non-febrile seizures and eye related disorders.
  • When comparing various antiretroviral medications, we found that children of women whose ART regimen included efavirenz were more likely to be diagnosed with a neurologic condition than children of women whose ART regimen did not include efavirenz (9.6% vs. 6.2%). This translated to a 60% higher risk of being diagnosed with a neurologic condition in the efavirenz exposed group after controlling for other risk factors.
  • We also found a suggestion of an association between in utero dolutegravir exposure and later diagnosis of a neurologic condition but the number of children exposed to dolutegravir was small (number of exposed children = 94).

MedicalResearch.com Interview with: "150826-fentanyl-factory-underground-illicit.jpg" by r. nial bradshaw is licensed under CC BY 2.0 Jon Zibbell, PhD, Senior public health scientist Behavioral Health Research Division RTI International Research Triangle Park, NC,  MedicalResearch.com: What is the background for this study? What are the main findings? Response: For the first time in 2016, U.S. overdose deaths involving illicitly-manufactured fentanyl surpassed deaths from heroin and prescription deaths. Fentanyl is an extremely potent synthetic opioid, and an illicitly-manufactured form of the drug is regularly being mixed with heroin and often sold to unwitting consumers. Fentanyl is 50 times more potent than heroin and its illicitly-manufactured version is extremely difficult to discern when mixed with heroin. Harm reduction organizations have started to distribute FTS and people consuming street-purchased opioids are using them to test drugs for fentanyl. Our objective was to assess whether this point-of-use form of drug checking was influencing people’s drug use behavior. The study was self-funded by the research institute RTI International. Our findings show that consumers who tested street opioids with fentanyl test strips were five times more likely to engage in safer drug use behavior when the test comes back positive. The study was conducted among a group of 125 people who inject drugs in Greensboro, North Carolina. (more…)
Author Interviews, MRSA / 05.10.2018

MedicalResearch.com Interview with: Kathryn Dalton, VMD MPH AKC CHF Fellow PhD Student, Davis Lab Environmental Health and Engineering Johns Hopkins Bloomberg School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Animal-assisted interventions (or AAI for short) have become increasing popular in hospitals for the emotional and physical benefits they bring to patients. But there is a risk that these therapy dogs could potential spread infectious germs, including MRSA (methicillin-resistantStaphylococcus aureus), to patients. Our study found that therapy dogs can spread MRSA to patients, and children who had more contact with the therapy dog were at higher risk of getting MRSA. But, we used a new cleaning protocol on the dog with an anti-septic shampoo before the visit and anti-septic wipes during the visit. Patients who had more contact with the dog did not have a higher risk of MRSA when the dog was giving this new cleaning protocol, which made the AAI therapy visits safer for the patients. In addition, the patients’ emotional and physical benefits we observed were not changed by using this dog cleaning protocol.       (more…)

MedicalResearch.com Interview with: Dr. Ernest Loumaye, MD, PhD Co-Founder and CEO ObsEva SA   MedicalResearch.com: What is the background for this announcement? How does Nolasiban work to decrease contractions and improve uterine blood flow? Response: The WHO has recognized infertility as a global health issue, and many couples undergo IVF treatment: there are more than 700,000 annual IVF treatment cycles in Europe and more than 200,000 in the U.S. However, more than 50% of IVF procedures do not result in pregnancy, and failure has tremendous emotional and financial costs to patients.  ObsEva is dedicated to improving fertility outcomes in IVF while also supporting the use of single embryo transfer to minimize multiple births that are associated with significant health risks to mother and baby, as well as significant health costs from premature delivery. Nolasiban works by blocking the hormone oxytocin, which is known to induce uterine contractions.  Nolasiban reduces uterine contractions and could improve uterine blood flow, both effects being favourable for the embryo to properly implant.
