MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Tuberculosis infection is one of the most common infectious diseases in the world.
Although less common in the United States, many people still become infected every year and are at risk of getting sick and spreading the infection to others. We know there are effective screening tests that can detect latent tuberculosis infection before people become sick with active tuberculosis disease. Additionally, there are effective treatments to prevent people from progressing from latent tuberculosis infection to active tuberculosis disease.
Thus, for people with increased risk of contracting tuberculosis, the Task Force recommends screening for latent tuberculosis infection.
People who are considered at increased risk include those who were born in or have lived in countries where tuberculosis is highly prevalent, or who have lived in congregate settings where exposure to tuberculosis is more likely, such as homeless shelters or correctional facilities.
08 Sep MRI Generally Safe For Fetus in First Trimester, But Gadolinium Should Be Avoided Unless Strongly Indicated

MedicalResearch.com: What is the background for this study?
Response: Hereditary hemorrhagic telangiectasia (or Osler-Weber-Rendu Syndrome) is a genetic vascular malformation syndrome that results in arteriovenous malformations. This syndrome is found in 1:5000 individuals, and is inherited in autosomal dominant fashion. It is often under diagnosed by the medical community (some estimate that 90% of patients do not know that they are affected).
In the skin and mucous membranes small AVMs - termed telangiectasias - form, and they have the potential to rupture and bleed. This happens most commonly in the nose, and 95% of patients with HHT have recurrent nose bleeding (epistaxis). While other dangerous internal organ AVMs also form, epistaxis is the most important determinant of quality of life for these patients. This epistaxis can lead to anemia, heart failure and rarely death. Patients often seek therapy for epistaxis, but cautery or laser treatment of the telangiectasias tends to provide only temporary benefit. Definitive therapy to eliminate epistaxis requires surgical closure of the nasal passages, and is too drastic for most patients.
We sought to test medical therapy for HHT-related epistaxis with our best candidate drugs in nose spray form. The drugs with the most anecdotal support include bevacizumab (an anti-angiogenic drug), estriol (an estrogen), and tranexamic acid (an inhibitor of fibrinolysis). Our patients received a nose spray with one of these drugs or a saline placebo and used two sprays in each nostril daily for 12 weeks and recorded their nose bleed frequency and duration in a daily diary.
08 Sep Cord Blood Transplant in Leukemia With Minimal Residual Disease

MedicalResearch.com: What is the background for this study?
Response: When first introduced, cord blood (CB) graft was used only as a last resort when no suitable conventional donor could be identified, largely due to the limiting cell doses available in a cord blood graft. A CB graft, however, is attractive due to the increased level of HLA disparity that can be tolerated, without increased risk of graft versus host disease, allowing nearly all patients to find such a donor.
The main intent of the study was to evaluate whether or not, at our Institution, cord blood SHOULD STILL BE considered only AS an alternative DONOR or IF instead outcomes were comparable to those obtained with more “conventional” types of transplants from matched and mismatched unrelated donors.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Putting drops in the eye is well accepted from the standpoint of practitioners but is problematic for many patients. Therefore, particularly in cases where multiple drops are required in a day such as is the case with certain infections for example or a lifetime of drops is required such as is the case with diseases like glaucoma, patient compliance is a real issue. In addition, as much as 95% of any drop instilled in the eye is lost within the first 5 minutes, meaning that drug concentrations within the drop need to be higher to ensure that the required dose gets into the patient’s eye.
Therefore there is a real need for a better alternative to traditional eyedrops is needed. We have developed a new method of formulating drugs for delivery as drops that adhere to the mucous layer of the tear film, allowing for smaller amounts of drug to be delivered over a prolonged period of time. This means that fewer drops with lower drug concentrations can be delivered. This is a micelle based system that allows for the formulation of more hydrophobic drugs. A mucoadhesive component associated with the micelle binds to the mucin layer of the tears, meaning that the residence time on the eye is similar to that of this layer - between 4 and 7 days. Drug is slowly released from the micelle, allowing for prolonged treatment.

MedicalResearch.com: What is the background for this study?
Response: “Innate immunity” is the body’s natural resistance to microbial infection and stands in contrast to “adaptive immunity,” which is the body’s learned response to infection (e.g. antibodies and vaccines). In the standard model of innate immunity that has emerged over the last several decades, scientists have come to understand that the human genome encodes many “receptors” that have evolved as sensors for specific common microbial molecules, such as bacterial or viral DNA or components of bacterial or fungal cell walls. The job of these receptors is to survey the environment (skin, blood, etc.) for potentially dangerous microbes and initiate inflammatory responses if they are found. These activities are essential for defense against infection, and people and animals with defects in these sensors or the responses they trigger can be susceptible to infection.
My laboratory has been interested for more than a decade in identifying these innate sensors and the microbial targets that they recognize. In this study, we were looking for the sensor that allows white blood cells (e.g. macrophages and dendritic cells) to detect Gram-positive bacterial cell walls and trigger a specific inflammatory response: secretion of the potent inflammatory mediator interleukin-1β (IL-1β).

Response: In the US, food allergy has become one of the more common childhood medical conditions diagnosed in young children. Antibiotics are frequently prescribed in young children, and research continues to reveal that as many as 30% of antibiotic prescriptions are not appropriate.* We sought to examine if there was an association between antibiotic prescription and food allergy diagnosis.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: As a group we were concerned about the misinformation that continues to be promulgated on the internet and through other sites. Importantly, the group consisted of experts with specific experience in the management of head louse infestations, from pediatric dermatology, pediatrics, school nursing and head louse research fields. Even information sources that we would have expected to be credible are outdated, unreliable or both, often continuing myths about head louse infestations and how they can be controlled. We wanted to provide a balanced and informed perspective that would help physicians and parents recognize that head louse infestations do not present a serious problem, and can be well managed with an informed approach to treatment.
The main findings are that over the counder products (permethrin/pyrethrins) are unlikely to be effective, and that that there are safe and effective products that are available by prescription.
Interestingly, head lice do affect Indian and African children in their home countries, but virtually nonexistent in African Americans in North America. There has been speculation about hair grooming regimen or structure of African American hair but the cause is unknown. In a study we performed assessing resistance to over the counter pediculicide components over a decade ago in Baltimore, we were not able to find a single African American child with head lice. We were not able to recruit any patients from the Baltimore City Schools.
07 Sep Real World Trial Show Efficacy of Fluticasone Furoate–Vilanterol for COPD in Clinical Practice
MedicalResearch.com Interview with: Jørgen Vestbo DMSc FRCP FERS Professor of Respiratory Medicine Division of Infection, Immunity and Respiratory Medicine University of Manchester Education and Research Centre University Hospital of South Manchester Manchester MedicalResearch.com: What is the background for this study? What are the main findings? Response: Efficacy studies are limited in their usefulness to clinicians as there are often restricted inclusion criteria, with many exclusion criteria and patients are followed closely with high adherence to study treatment. They therefore show what the drugs can do but not necessarily what they do do in the real world. Randomised studies in everyday practice, not limiting the entry (effectiveness trials) are therefore needed. In our study we showed that it is feasible to do randomised studies in the “real world”. Our study showed that a simple treatment with a once-daily combination of an inhaled corticosteroid and a long-acting beta-agonist (Breo/Relvar) was superior to the usual care chose by the patients’ general practitioners to manage their COPD.07 Sep Which Come First? Atopic Dermatitis or Staph Aureus Colonisation?

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The background is that atopic dermatitis (AD) has a close relationship with staphylococcus aureus (SA) colonisation, and this is known to drive flares or exacerbations of AD but before our report it was not known which came first-AD colonisation or atopic dermatitis?
By following a cohort pf patients very carefully over a 1 year period and regularly sampling their skin microbiome we were able to show that SA colonisation did not precede development of AD and in fact that several non SA species of staphylococcus actually appeared to be protective for developing atopic dermatitis.
This is an important new finding in the complex relationship between the microbiome and skin inflammation, suggesting that some commensal bacterial are anti-inflammatory or protective.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Circulating progenitor or stem cells were discovered in adults 15 years ago. We now know that they may be stimulated by injury or ischemia, and they go down in number and function with aging, particularly when aging is associated with risk factors.
Women with chest pain despite normal coronary arteries are thought to have ischemia because of microvascular dysfunction. We found that these women, with the worst microvascular function (measured as coronary flow reserve), had higher levels of circulating stem or progenitor cells. This implies that the mild ischemia they are having during their normal daily life, leads to stimulation of their stem cells. Also, the vascular abnormality may be a stimulus for repair.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The study found that overall past year marijuana use by adults in the U.S. increased by more than 30% in the past dozen years, and 10 million more people were using marijuana in 2014 than in 2002. Use of marijuana on a daily (or near daily) basis increased even more markedly. In 2002, 3.9 million adults in the U.S. reported using marijuana daily or nearly every day, and the number more than doubled to 8.4 million by 2014. Along with this increase in use, we found that U.S. adults perceptions of the potential harms from using marijuana greatly decreased. Despite scientific evidence of potential harms, adults are much less convinced about dangers associated with using marijuana. These reductions in perceived harm were strongly associated with the increases in use.

Response: Little was previously known about the timing of extubations for mechanically ventilated intensive care unit patients or whether extubating patients overnight is safe. In this retrospective cohort study of mechanically ventilated intensive care unit adult patients in the United States, 20.1% were extubated overnight. Overnight extubation was associated with significantly higher hospital mortality.

MedicalResearch.com: What is the background for this study?
Response: The background of this study was to investigate the time trends in the prevalence of celiac disease and gluten-free diet in the United States using most recent 6-year National Health And Nutrition Examination Survey. Previous studies using narrow populations or old study period mainly before mid 2000s suggested increasing prevalence of celiac disease. At the same time, there is a current popular trend of people following gluten-free diets beyond what would be expected if it were solely due to the increasing prevalence of celiac disease.
06 Sep Overweight Girls, Underweight Boys May Be At Greater Risk of Adult Asthma
MedicalResearch.com Interview with: Professor Charlotte Suppli Ulrik MD DMSc et al. Dept. of Respiratory Medicine Hvidovre Hospital Copenhagen, Denmark MedicalResearch.com: What is the background for this study? Response: Obesity is a risk factor for new-onset asthma, but the association is incompletely understood. Our aim was, therefore, to investigate the association between body mass index (BMI) BMI in childhood and asthma admissions in early adulthood (until age 45 years). We used data on BMI measured annually (age 7-13 years) in 321,830 children enrolled in the Copenhagen School Health Records Registry. During the 36-years of follow-up, a total of 2,059 first-time ever hospital admissions for asthma were observed.06 Sep Origins of Childhood Asthma Can Be Traced To Very Early in Pregnancy

MedicalResearch.com: What is the background for this study?
Response: For almost thirty years there has been evidence that we are all born with a certain predisposition to what are called non communicable diseases (NCD) such as high blood pressure, type II diabetes and heart disease.
The evidence comes from studies which have linked reduced birth weight with increased risk for these NCDs in later life. The question which arises, and which has been more difficult to answer, is “when during pregnancy is the predisposition to for NCDs first seen?”
This is important to any attempt to reduce the unborn baby’s risk for NCD. We and other researchers have used fetal ultrasound data to link size before birth to non communicable diseases outcomes. In childhood, NCDs include asthma.
06 Sep Uncertainty Persists About Benefits of Delayed Cord Clamping In Extremely Premature Infants

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: In an analysis of trials of placental transfusion at delivery by either delayed umbilical cord clamping or cord milking in infants born before 30 weeks gestation, placental transfusion was associated with short term benefits including increased hemoglobin, fewer blood transfusions, improved blood pressure and reduced late onset sepsis, with no significant effect on other outcomes. There were insufficient data regarding effects of placental transfusion on survival and long term disability.
The Australian Placental Transfusion Study (APTS) is a randomised controlled trial that aims to determine if delayed cord clamping (≥ 60 seconds) compared to early cord clamping (≤10 seconds) in 1600 infants born before 30 weeks gestation results in improved newborn outcomes and disability free survival.
In this echocardiographic sub study, the aim was to determine the effect of placental transfusion on systemic blood flow in the first day after birth in 266 infants randomly allocated to delayed versus early cord clamping (133 infants in each group). The primary outcome was superior vena cava (SVC) flow (cardiac input) which overcomes the problem of shunts across the adapting heart which affect the usefulness of measuring ventricular outputs in the first days after birth.
In infants born <30 weeks gestation, delayed cord clamping had no effect on the principle measure of systemic blood flow (SVC flow) during the first 24 hours compared to immediate cord clamping. However, right ventricular output (RVO) was lower in the delayed cord clamping group. This was not predicted and may be a chance finding. Further analysis suggests the effect of cord clamping on RVO could be mediated by its effect on hemoglobin. This may be a positive or negative adaptive change. There was no evidence of an increase in right to left ductal shunting suggestive of high pulmonary blood pressure to explain the difference in RVO. Delayed cord clamping resulted in a 8.9g/L greater increase in hemoglobin to 6 hours but had no effect on ductus arteriosus size, shunt direction or treatment, no effect on blood pressure or its treatment, and no effect on blood gas parameters and other cardiovascular variables in the first 24 hours.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Surviving childhood cancer has dramatically and increasing improved to the point where more than 80% will achieve a 5-year event free survival. Many of these survivors look forward to decades of active productive life.
More than half of these survivors have been treated with therapies know to be associated with late cardiotoxicity that can be pervasive, persistent, and progressive and associated with cardiovascular morbidity and mortality. In this article we review both the course and prevention of this cardiotoxicity. We focus in part on anthracycline chemotherapy that is widely used and known to be cardiotoxicity.
We further review studies we and others have conducted to examine the effectiveness of dexrazoxane, an iron chelator, that when given before each anthracycline dose results in anthracycline cardioprotection for long term survivors. In some reported studies this has allowed for higher cumulative anthracycline doses to be safely given. In other cases this has allowed for simultaneously being able to safely treat children with malignancies that would be refractory to conventional therapy more potent therapies that would normally have additive cardiotoxicity.

MedicalResearch.com: What is the background for this study?
Response: For several years we have been investigating the causes of immersion pulmonary edema (IPE, also known as swimming-induced pulmonary edema or SIPE). We determined that during exercise while immersed in cold water pulmonary artery and wedge pressures of individuals who are SIPE-susceptible are higher than normal. This demonstrated that SIPE is a form of hemodynamic pulmonary edema. It is certainly plausible that SIPE could cause death, and indeed a few fatal cases had been reported in the medical literature, mostly in scuba divers. After reading of deaths in young, apparently fit and healthy triathletes we hypothesized that some of these deaths were probably due to swimming-induced pulmonary edema . It is easy to diagnose SIPE in a living individual, using a stethoscope or chest x-ray/CT. However, since almost anyone who dies from any cause, particularly if attempted resuscitation has occurred, will have pulmonary edema at autopsy. Before concluding that death has occurred due to SIPE, other clues are therefore necessary.
04 Sep Math Algorithm Helps Predict Recurrence of Prostate Cancer
MedicalResearch.com Interview with:
Ilaria Stura PhD
Università degli Studi di Torino Turin, Piedmont, Italy
MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Man has always tried to predict the future, especially to prevent catastrophes, diseases and death. In this case, we want to prevent the ‘personal catastrophe’, i.e. the spread of the disease (recurrence of prostate cancer) in the patient. Our work therefore belongs to the so-called ‘personalized medicine’, a very important and innovative clinical approach.
In particular this study may potentially improve the quality of life of the patients and help the clinicians, since it could give valuable information to the urologist, for example reporting that the growth velocity of the tumor is increasing and that a relapse is expected within few months. With this information, the clinician could chose the best therapy for the patient (e.g. hormone or radio therapy) in order to stop the spread of the disease or, conversely, the use of drugs can be delayed if not necessary. Obviously clinicians already try to do this, based on their experience, but our method provides further confidence in their 'investigation' work, since the algorithm is validated on data coming from a database much larger than his/her personal experience.04 Sep Americans Increase Marijuana Use as Perceived Risk Falls

MedicalResearch.com: What is the background for this study? What are the main findings?
Response:
-In the United States, marijuana is the most commonly used illicit drug. Because of certain state-level policies that have legalized marijuana for medical or recreational use, population-based data on marijuana use and other related indicators are needed to help monitor behavioral health changes in the United States.
- This SAMHSA surveillance report represents an overview of national estimates for marijuana use and other related indicators among the U.S. noninstitutionalized civilian population aged ≥12 years using 2002–2014 National Survey on Drug Use and Health data. The report includes at least seven important findings. Find more detailed information atSAMHSA surveillance report. Since 2002, marijuana use in the United States has increased among persons aged ≥18 years, but not among those aged 12–17 years. A decrease in the perception of great risk from smoking marijuana combined with increases in the perception of availability (i.e., fairly easy or very easy to obtain marijuana) and fewer punitive legal penalties (e.g., no penalty) for the possession of marijuana for personal use might play a role in increased use among adults.

MedicalResearch.com: What is the background for this study?
Response: Prior research has demonstrated that readmission in the first 30 days after percutaneous coronary intervention (PCI) is common, reported around one in six or seven Medicare beneficiaries, and that many are potentially preventable. Since 2000, there have been significant changes in the management of coronary artery disease and the use of PCI. Additionally, in the last decade, readmission rates have become a major focus of research, quality improvement and a public health issue, with multiple resulting national initiatives/programs which may be affecting care. Therefore, in this study, we sought to examine contemporary trends in readmission characteristics and associated outcomes of patients who underwent PCI using the Medicare database from 2000-2012.

MedicalResearch.com: What is the background for this study?
Response: Current chemotherapeutic regimens while effective are difficult for patients and affect their quality of life. Our research tackles this issue by designing a nanotherapy that can deliver multiple chemotherapeutic agents by targeting the entire tumor microenvironment and not just the cancer cells and by reducing drug resistance. This, then is intended to simplify the treatment regimen, reduce drug related side effects and extends the life of the drugs by preventing resistance should the patient need it in the future. Thus, the ultimate underlying goal is to improve the patient’s quality of life by not just maximizing the drug’s efficacy but also trying to decrease its impact on the overall lifestyle of the individual.
04 Sep No Evidence of Worse STEMI Outcomes During Off-Hours

Senthil Selvaraj, MD, MA and Deepak L. Bhatt, MD, MPH
Brigham and Women’s Hospital Heart & Vascular Center and
Harvard Medical School, Boston, MA
MedicalResearch.com: What is the background for this study? What are the main findings?
Response: There has been significant controversy in the effect of off-hours presentation in ST-elevation myocardial infarction (STEMI). Off-hours presentation has been associated with longer treatment time, an independent predictor of worse outcomes in STEMI, though a number of other studies have shown no difference as well. Moreover, little data has been generated from clinical trials, which has the advantage of comprehensive and adjudicated outcomes.
In our analysis of nearly 2,000 STEMI patients from the CHAMPION PHOENIX study (a randomized, controlled trial of cangrelor in percutaneous coronary intervention), we found that off-hours presentation was not associated with worse efficacy or safety outcomes at 48 hours or 30 days. More specifically, outcomes not typically reported in registry data, such as ischemia-driven revascularization and stent thrombosis, were not significantly different between the groups. Interestingly, treatment times were actually faster in the “off-hours” group as well.
03 Sep Chemical Sunscreens May Reduce Male Fertility
MedicalResearch.com Interview with: Anders Rehfeld MD, PhD Student Faculty of Health and Medical Sciences Department of Cellular and Molecular Medicine University of Copenhagen Copenhagen Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: Human fertility is declining in many areas of the world and the reason is largely unknown. Our study shows that 44% of the tested chemical UV filters can induce calcium signals in human sperm cells, thereby mimicking the effect of progesterone. Progesterone-induced calcium signals, and the sperm functions it triggers, is absolutely essential for the human sperm cell to normally fertilise the human egg.03 Sep Poor Work/Life Balance Cited As Main Reason For Few Female Surgeons
MedicalResearch.com Interview with: Miss Hui-Ling Kerr SpR Trauma and Orthopaedics Department of Trauma and Orthopaedic Bristol Royal Infirmary, Bristol, UK MedicalResearch.com: What is the background for this study? Response: Gender inequality at consultant level in surgery has not improved despite greater opportunities for women and only a small proportion of women apply to become surgical trainees. We wanted to find out if the lack of female surgical role models acted as a deterrent to first year female junior doctors and final year medical students towards a career in surgery.02 Sep Intensive Diabetes Treatment Extends Life On Average 8 Years, Free of Serious Complications
MedicalResearch.com Interview with: Oluf Pedersen, MD Specialist in Internal Medicine and Endocrinology, The Novo Nordisk Foundation Center for Basic Metabolic Research, Section of Metabolic Genetics, Faculty of Health and Medical Sciences, University of Copenhagen, Peter Gæde and Jens Oellgaard Department of Cardiology and Endocrinology Slagelse Hospital Copenhagen MedicalResearch.com: What is the background for this study? What are the main findings? Response: The Steno-2 study was the attempt to investigate the effect of an intensified, multifactorial intervention in type 2 diabetes simultaneously targeting risk factors such as hyperglycaemia, hypertension, dyslipidaemia, blood platelet aggregation, and elevated urinary albumin excretion rate as well as life style factors such as smoking, diet and a sedentary lifestyle. On top of that patients were by a dedicated team of care givers offered continued education and motivation. A total of 160 Danish type 2 diabetes patients with microalbumuria (a biomarker of generalized vascular damage) were originally randomized either to intensified multifactorial treatment at Steno Diabetes Center, Copenhagen or to conventional multifactorial treatment at their general practitioners. The trial ended after 8 years, and patients in both of the original treatment arms were for the following 13 years given intensified multifactorial treatment as the one originally given to the intensified intervention group only. Three previous milestone reports from the Steno-2 trial published in Lancet and New England Journal of Medicine have provided unprecedented evidence that this targeted and multifaceted approach reduces the risk of diabetic late complications such as kidney, eye or nerve disease as well as cardiovascular disease and total mortality with around fifty percent.02 Sep Cancer Patients Have Increased Risk of Injuries Around Time of Diagnosis

Response: Injury, either iatrogenic (for example, complications from medical procedures and drug treatment) or non-iatrogenic (for instance, suicidal behavior and accidents), is one of the leading causes of non-cancer mortality for patients diagnosed with cancer. Iatrogenic injuries are common in those with cancer and have been shown to increase mortality in some cancer patients. Increased risks of suicide and accidental death after diagnosis have been reported, and the diagnostic process of cancer has been recognized highly stressful. It is, however, unknown whether the risk of injuries is also increased during the time period before receiving the diagnosis. Actually confirming a diagnosis can often be difficult due to patients sometimes concealing information. This is why Motivational Interviewing is important. Anyway, we analysed the risks of injuries during the weeks before and after diagnosis using a nationwide study sample in Sweden.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: No study based on a US cohort undergoing current procedures has examined weight change comparing surgical patients and nonsurgical patients for as long as we have. This is the first study to report 10-year outcomes on gastric bypass patients and compare them to matched patients who did not get surgery. At 1 year, gastric bypass patients lost 31% of their baseline weight compared controls who only lost 1.1% of their baseline weight. At 10 years, gastric bypass had lost 28% of their baseline weight.
We also compared weight loss at 4 years for Veterans who received the 3 most common procedures (gastric bypass, sleeve gastrectomy, and adjustable gastric banding). At 4 years, patients undergoing gastric bypass lost more weight than patients undergoing sleeve gastrectomy or gastric banding. Given that few high quality studies have examined sleeve gastrectomy to 4 years, the 4-year sleeve outcomes contribute to filling this important evidence gap as the sleeve gastrectomy is now the most commonly performed bariatric procedure worldwide.
