Medical Research: What is the background for this study?
Dr. Rowan: Clinicians are interested in screening during early pregnancy to identify women with previously unrecognised diabetes, as these women have increased risks of adverse pregnancy outcomes. HbA1c is a simple and reproducible measure of glucose elevations, but its usefulness as an early pregnancy screening test is not clear. The aim of this study was to examine whether pregnant women with an HbA1c of 41-49mmol/mol (5.9-6.6%) are a high risk subgroup and whether treating these women from early pregnancy improves outcomes compared with identifying them during routine screening for gestational diabetes (GDM) from 24 weeks’ gestation.
This observational study compared women referred to the diabetes clinic <24 weeks’ who had an early pregnancy HbA1c of 41-49mmol/mol (5.9-6.6%) with women who, at the time of diagnosis of GDM ≥24 weeks’ (typically by 75gOGTT), had an HbA1c of 41-49mmol/mol (5.9-6.6%). Both groups were compared with women diagnosed with GDM who had a lower HbA1c at diagnosis.

MedicalResearch.com Interview with:
Christina Y. Weng, MD, MBA
Assistant Professor-Vitreoretinal Diseases & Surgery
Baylor College of Medicine-Cullen Eye Institute
Medical Research: What is the background for this study? What are the main findings?
Dr. Weng: Telemedicine has been around for a long time, but only recently have technological advances solidified its utility as a reliable, effective, and cost-efficient method of healthcare provision. The application of telemedicine in the field of ophthalmology has been propelled by the development of high-quality non-mydriatic cameras, HIPAA-compliant servers for the storage and transfer of patient data, and the growing demand for ophthalmological care despite the relatively stagnant supply of eye care specialists. The global epidemic of diabetes mellitus has contributed significantly to this growing demand, as the majority of patients with diabetes will develop diabetic retinopathy in their lifetime.
Today, there are over 29 million Americans with diabetes, and diabetic retinopathy is the leading cause of blindness in working age adults in the United States. The American Academy of Ophthalmology’s and American Diabetes Association’s formal screening guidelines recommend that all diabetic patients receive an annual dilated funduscopic examination. Unfortunately, the compliance rate with this recommendation is quite dismal at an estimated 50-65%. It is even lower amongst minority populations which comprise the demographic majority of those served by the Harris Health System in Harris County, Texas, the third most populous county in the United States.
In 2013, the Harris Health System initiated a teleretinal screening program housed by eight of the district’s primary care clinics. In this system, patients with diabetes are identified by their primary care provider (PCP) during their appointments, immediately directed to receive funduscopic photographs by trained on-site personnel operating non-mydriatic cameras, and provided a follow-up recommendation (e.g., referral for in-clinic examination versus repeat imaging in 1 year) depending on the interpretation of their images. The images included in our study were interpreted via two different ways—once by the IRISTM (Intelligent Retinal Imaging Systems) proprietary auto-reader and then again by a trained ophthalmic specialist from the IRISTM reading center. The primary aim of this study was to evaluate the utility of the auto-reader by comparing its results to those of the reading center.
Data for 15,015 screened diabetic patients (30,030 eyes) were included. The sensitivity of the auto-reader in detecting severe non-proliferative diabetic retinopathy or worse, deemed sight threatening diabetic eye disease (STDED), compared to the reading center interpretation of the same images was 66.4% (95% confidence interval [CI] 62.8% - 69.9%) with a false negative rate of 2%. In a population where 15.8% of diabetics have STDED, the negative predictive value of the auto-reader was 97.8% (CI 96.8% - 98.6%).

Christine Veenstra MD
Clinical Lecturer, Internal Medicine

MedicalResearch: What is the background for this study? What are the main findings?
Dr. Veenstra: Patients with cancer face many costs and incur financial burden as they go through diagnosis and treatment. For working patients, cancer diagnosis and treatment may come with the additional burden of time away from work, lost income, and even long-term job loss. Although 40% of US workers do not have access to paid sick leave, we hypothesized that availability of paid sick leave could reduce the need to take unpaid time away from work during cancer treatment and might therefore be associated with job retention and reduced personal financial burden.
In a survey of over 1300 patients with Stage III colorectal cancer, we found that only 55% of those who were employed at the time of their cancer diagnosis retained their jobs. Working patients with paid sick leave were nearly twice as likely to retain their jobs compared with working patients who did not have paid sick leave. This held true even when controlling for income, education and health insurance. Furthermore, working patients without paid sick reported significantly higher personal financial burden than those who had paid sick leave available.

University College, Oxford
Medical Research: What is the background for this study?
Dr. Rahman : Up to TIME1, the evidence base behind optimal pleurodesis for malignant pleural effusion in terms of tube size and analgesia was poor. Optimal pleurodesis in this context is one which is successful (i.e. the patient needs no further pleural interventions for that malignant effusion), but occurs with the minimum discomfort. This is particularly important as the treatment intent in malignant effusion pleurodesis is palliative.
This is the first adequately powered randomized trial to address two important issues in pleurodesis for malignant pleural effusion - that of whether NSAIDs reduce pleurodesis efficacy, and if smaller chest tubes (12F) are "as good as" larger chest tubes (24F) for pleurodesis success and in terms of pain.
Medical Research: What are the main findings?
Dr. Rahman : The main and somewhat surprising findings are that:

Medical Research: What is the background for this study?
Dr. Subbotina: Exercises represent the most natural and effective way to maintain physical and metabolic well-being. Lack of physical activity can contribute to many preventable diseases such as cardiovascular disease, stroke, cancer, diabetes and obesity.
It is known that moderate exercise is beneficial for health but the mechanism of this effect is only partially understood. It becomes more and more evident that skeletal muscles function as an organ that produces and secretes biologically active molecules called myokines. Studies of the biological role and mechanism of action of myokines are important for understanding of muscle function under sedentary and exercise conditions.

Medical Research: What is the background for this study? What are the main findings?
Dr. Van Naarden Braun: Over the past five decades, remarkable improvements have been made in obstetric and neonatal care resulting in significant declines in infant mortality both in the US and abroad, particularly for infants born premature and very low birthweight. Successes in neonatal survival have been met by concerns that the occurrence of developmental disabilities, most notably cerebral palsy, would increase. By monitoring changes over time in the prevalence of cerebral palsy, we can try to understand the impact of these advances further. Our recently published study reported that the

Past Chair, AANS/CNS Cerebrovascular Section
Medical Research: What is the background for this study? What are the main findings?
Dr. Amin-Hanjani: Posterior circulation strokes account for up to 30% of all ischemic strokes, and atherosclerotic occlusive disease of the vertebrobasilar (VB) is responsible for approximately one third of these cases. Symptomatic atherosclerotic VB occlusive disease is associated with a high risk of recurrent stroke despite medical therapy, in the range of 10-15% within 2 years. There have been advances in treatment options, particularly endovascular angioplasty and stenting, aimed at reverting the blockage; however these procedures themselves carry risks, and are likely to benefit only selected patients who are at highest risk without intervention. Our study, VERiTAS, aimed to determine if measurement of blood flow in the posterior circulation vessels could identify the high risk patients. Flow measurements were performed using the technique of quantitative magnetic resonance angiography (QMRA) relying on standard MR sequences and the commercial software NOVA. These flow measurements were used to designate patients presenting with symptomatic vertebrobasilar disease as flow compromised or not, and patients were then followed for a median of 23 months in a blinded fashion to determine the risk of subsequent strokes. We found that among 72 such patients, only one quarter (18 patients) demonstrated flow compromise on QMRA, but that this group had a significantly higher risk of subsequent stroke at one year, 22% vs only 4% in the other group. The hazard ratio for subsequent stroke was markedly elevated at 11.5 even after adjusting for age and other stroke risk factors.

Abigail Sewell PhD
Assistant Professor of Sociology
Emory University
Medical Research: What is the background for this study?
Dr. Sewell: Ethnoracial minorities report poorer quality of care than do whites. However, one key dimension of health care quality - trust in one's personal physician - indicates mixed associations with race. This study examines five dimensions of the patient-physician relationship independently of each other to identify the aspects of health care where minorities feel most alienated from their doctors.
Medical Research: What are the main findings?
Dr. Sewell: The results of the study show that Blacks and Latinos are less likely to believe that their doctors really care about them as a person than are Whites.

Medical Research: What is the background for this study? What are the main findings?
Dr. Freudenheim: There have been a number of studies that have shown an association between periodontal disease and chronic diseases, particularly stroke and heart attacks. There is also some newer evidence that periodontal disease is associated with cancer, particularly cancers of the gastrointestinal tract. Ours is the first large prospective study of periodontal disease and breast cancer.
This was part of a study of more than 70,000 postmenopausal women from throughout the United States, the Women’s Health Initiative. Women provided information about their health and other related factors and then those women were followed to see who developed certain diseases.
We found that women who had been told that they had periodontal disease were more likely to develop breast cancer. In particular, women who were former smokers (quit within the last 20 years) and who had periodontal disease were at increased breast cancer risk. There was a similar increase in risk for current smokers with periodontal disease but it was not statistically significant. (There was a relatively small number of current smokers in the WHI study.)

Response: Online physician rating sites allow patients to recommend, grade, and publicly comment on physician performance. Despite increases in physician rating website popularity, little information exists regarding the online footprint of dermatologists. Many physicians also remain wary of these websites for fear of malicious reviews.
Our study aimed to investigate the patterns of dermatologist online ratings. We found the average ratings for dermatologists were high, >3.5 stars, on the top 5 websites (ZocDoc, Healthgrades, Yelp, RateMDs, and

Florence Leclercq, MD, PhD

Medical Research: What is the background for this study? What are the main findings?
Response: Patients with history of coronary artery disease (CAD) are considered as a population with high risk of further coronary events. However, frequent pre-existing ECG changes observed in these patients result in difficulty interpreting new ECG aspects in case of chest discomfort. Furthermore, anxiety frequently induced non-cardiac causes of chest pain in these patients, leading to unjustified admission to cardiology units. Moreover, levels of troponin are usually higher in patients with previous CAD compared to patients without history of angina, resulting in difficulty interpreting baseline values in this population. Conversely, copeptin may be influenced by the severity of myocardial ischemia and resulting endogenous stress, and could be a useful additional marker to exclude severe coronary stenosis in high-risk patients with recent chest pain.
This propective monocentric study evaluates the incremental value of copeptin associated with high-sensitivity cardiac T troponin (hs-cTnT) to exclude severe coronary stenosis in 96 patients with coronary artery disease (CAD) and acute chest pain.
Mean age of patients was 60 +/- 13.8 years and the mean time between chest pain onset and blood samples of copeptin was 4.2 +/-2.7 hours. According to clinical decision, coronary angiography was performed in 71 patients (73.9 %) and severe stenosis diagnosed in 14 of them (14.6%). No ischemia was detected on SPECT imaging (n=25). Among the 69 patients with a negative kinetic of hs-cTnT and a negative baseline copeptin, 5 (7.4%) had a severe stenosis (NPV 0.93; 95% CI: 0.87-0.99), 4 of them related to in-stent restenosis (NPV for exclusion of native coronary stenosis: 0.98; 95% CI: 0.93-1).
We can conclude that in patients with preexisting CAD, and once Acute Myocardial Infarction (AMI) is excluded, copeptin increases the NPV of

Medical Research: What is the background for this study? What are the main findings?
Dr. Tevaarwerk: These patients were enrolled on a larger clinical trial known as the Symptom Outcomes and Practice Patterns study (SOAPP). SOAPP recruited breast, prostate, colon and lung cancer patients directly during outpatient oncology follow-up visits. All of the patients were recruited between May 2006 and May 2008.
The parent study recruited 3123 patients, of these 680 patients had metastatic disease and 668 had employment data.
Patients were asked if they were working and if there had been a change due to illness. We were able to compare those stably working with those who had changed to "no longer working" and look at factors that associated with this change (age, gender, cancer type, race/ethnicity, time since diagnosis, location of metastatic disease, type of treatment, performance status, number of metastases, symptom burden.)

Medical Research: What is the background for this study? What are the main findings?
Dr. Qi Sun: Potato is considered as a vegetable in certain dietary recommendations, such as in the U.S. MyPlate food guide, whereas in the U.K. national food guide, potato is grouped with cereal as sources of carbohydrates. Potato foods are typically higher in glycemic index and glycemic load, but data are rare regarding whether individual and total potato foods are associated with chronic diseases. In this analysis, we focused on diabetes and found that a higher consumption of total potato foods and individual potato foods, especially french fries, was associated with an increased risk of developing type 2 diabetes in three large cohort studies of ~200 thousand U.S. men and women. In addition, we found that increased potato food consumption over time was associated with a subsequent increased risk of developing diabetes.

Dr. Jennifer Stein MD
Associate Professor
Department of Ronald O. Perelman
Department of Dermatology
NYU Langone Medical Center
Medical Research: What is the background for this FDA decision? What is the issue surrounding tanning beds?
Dr. Stein: This is an important proposal from the FDA because it restricts minors from tanning and requires adults to sign an acknowledgement stating they have been informed about the risks of tanning.
There is clear evidence that indoor tanning significantly increases a person’s risk for skin cancer, including melanoma, a potentially deadly form of skin cancer.
It is important to protect young people from the dangers of tanning beds, especially because many patients report that they started indoor tanning as teens. There are 1.6 million minors using tanning beds every year.
MedicalResearch: What is the problem with tanning? Isn't a tan better than a sunburn?
Dr. Stein: Tanning beds deliver intense amounts of UVA. We know that UVA penetrates deep into the skin and causes mutations that lead to skin cancers, including melanoma. Tanning is a sign that skin cells have been damaged by UV light.

Medical Research: What is the background for this study?
Dr. Sarnyai: Schizophrenia has long been conceptualized as a disease contributed by the increased activity of the neurotransmitter system that provides dopamine for the brain. All clinically used antipsychotic drugs inhibit dopamine transmission in the brain by blocking dopamine receptors. These drugs have only a limited efficacy on a certain set of symptoms associated with schizophrenia. More recent research has uncovered that abnormal glucose and energy metabolism in the brain may contribute in the development of schizophrenia. This is not altogether surprising considering that our brain is using a disproportionately high amount of glucose to fuel neurotransmission (cell-to-cell communication in the brain), to maintain normal electrical activity of nerve cells and to deal with damaging free oxygen radicals. Therefore, even relatively small changes in the machinery that is required to provide energy for the brain cells can have very significant impact on brain function. In fact, recent studies have identified altered expression of genes and proteins that are responsible for enzymatic breakdown of glucose and proper handling of the metabolites to create the energy-rich molecule ATP. In addition, recent research shows decreased number and impaired function of the mitochondria, the powerhouses of the cell, in the brain of individuals with schizophrenia.
These recent results that show abnormal energy metabolism in schizophrenia raise the possibility of targeting metabolic pathways for therapeutic benefit in this condition. Ketogenic diet provides and alternative source of energy to the brain through fatty acids. Furthermore, since this diet is very low in carbohydrates, almost all the energy needs of the cells comes from breaking down fat (fatty acids) as opposed to glucose. This can circumvent the classic glucose metabolic pathways that maybe impaired in the disease. Also, breaking down fatty acids produces 40% more of the energy-rich molecule ATP than breaking down the carbohydrate glucose. Altogether, ketogenic diet may provide extra energy and can help neurotransmission in the brain, leading to the improvement of neurobiological processes underlying schizophrenia.

University of Southampton,
Southampton, UK
Medical Research: What is the background for this study? What are the main findings?
Dr. Wilks: The use of indwelling Foley urinary catheters for extended periods of time results in high risks of urinary tract infections (UTI) and catheter blockages. Blockages are often caused by the presence of Proteus mirabilis, a urease-producing bacterium which results in an increase of the urine pH and the development of crystalline biofilms. Biofilms develop when bacteria attach to a surface, forming a community structure, held together by extracellular polymeric substances (EPS). Once in a biofilm, bacteria exhibit high resistance to the action of antibiotics and are protected by other stress factors. The crystalline biofilms resulting from the presence of Proteus are highly complex environments and cause complete blockage of the catheter within days. Such blockages cause pain and trauma for patients, and result in high demands on healthcare resources.
In this study, we have used an advanced microscopy technique (episcopic differential interference contrast, EDIC microscopy developed by Best Scientific) to track the development of these crystalline encrustations on two commonly used catheter materials; silicone and hydrogel latex. We have identified four distinct stages to crystalline biofilm formation;

Medical Research: What is the background for this study? What are the main findings?
Dr. Schmid-Schonbein: Most approaches to control/reduce body weight focus on reducing food quantity, improving quality and promoting daily activity. These approaches, effective in the short term, only yield modest weight control. Weight management strategies recommended in the past have not significantly diminished the current trend towards childhood and adolescence obesity.
We developed and tested an alternative approach to control weight gain in healthy individuals to reduce the risk for development of obesity and diabetes complications. The essence is to:
“Eat deliberately slow AND stop eating when you feel no longer hungry”.
The approach avoids any form of special diet, uses no drugs, can be adopted for a lifetime and used in any ethnic environment. Children in a Mexican School in Durango were instructed by a pediatrician to learn to eat deliberately slow and to stop eating when the satiety reflex sets in, i.e. the moment when the feeling of hunger has disappeared.
They were instructed to:

Medical Research: What is the background for this study? What are the main findings?
Dr. Reinöhl: Aortic valve stenosis is a medical condition with very high short-term mortality. Previously its only treatment – therefore the gold standard – consisted of surgical valve replacement. Since 2007 transcatheter aortic-valve replacement (TAVR) can be considered alternative. Its impact on clinical practice, however, is largely unknown.
TAVR numbers rose from 144 in 2007 to 9,147 in 2013, whereas surgical aortic-valve replacement procedures only marginally decreased from 8,622 to 7,048. For both groups in-hospital mortality, as well as, the incidence of stroke, bleeding and pacemaker implantation (but not acute kidney injury) decreased.

Medical Research: What is the background for this study? What are the main findings?
Dr. Li Ding: Next-generation sequencing technologies have provided unprecedented opportunities for building a comprehensive catalog of point mutations, simple insertion and deletion mutations (indels) and structural variants in human cancers. Although significant progress has been made for documenting these common events through studies from individual research labs and large consortiums, there has been little progress in the discovery of complex indels after the transition from Sanger sequencing to NGS technologies. It is well known in the scientific community that indel detection using short next generation sequencing reads is a challenging problem. Our study, for the first time, directly addresses complex indel detection that has been barely touched in the cancer field. More importantly, our analysis discovered 285 complex indels in cancer genes such as PIK3R1, GATA3, and TP53, revealing an unexpected high prevalence of these events in human cancers.
