MedicalResearch.com Interview with: [caption id="attachment_47002" align="alignleft" width="200"]Sarah Anne Mbaeyi MD MPH Division of Bacterial Diseases CDC  Dr. Mbaeyi[/caption] Sarah Anne Mbaeyi MD MPH Division of Bacterial Diseases CDC  MedicalResearch.com: What is the background for this study? Response: College freshman living in residence halls, though not college students overall, have previously been identified as being at increased risk for meningococcal disease. However, these evaluations were conducted in the 1990s when rates of disease were higher, serogroup C was the predominant cause of disease, and before the availability of quadrivalent meningococcal conjugate (MenACWY) or serogroup B meningococcal (MenB) vaccines. MenACWY vaccine is routinely recommended for all adolescents at age 11 years and 16 years, as well as unvaccinated or undervaccinated college freshmen living in residence halls. MenB vaccine is not routinely recommended for all adolescents or college students, but may be administered to persons aged 16-23 years, with the preferred age of 16-18 years, based on clinical decision-making. Meningococcal vaccines are also recommended during an outbreak, and in recent years MenB vaccines have been used during multiple outbreaks on college campuses. In this evaluation, we aimed to describe the current epidemiology of meningococcal disease among college-aged young adults in the United States.

MedicalResearch.com Interview with: medicoreachLauren Williams Marketing Manager and  Research Analyst MedicoReach TwitterHandle: https://twitter.com/Lauren7321  MedicalResearch.com: What is the driving force behind the research and market study for estimating the hospitalist number in the US? Response: The existing physician’s database available in the industry comprises details that don’t specify the number of hospitalists in particular. As a result, it is turning out challenging to track and count the hospitalists amidst other specialties. There are a lot of incorrect estimations that are circulating, giving no clear picture. In a vast and growing industry like healthcare, there is no scope for wrong data as it can mislead others. Even the Physician Masterfile that the American Medical Association (AMA) offers do not cover the complete hospitalist population. This is because earlier the hospitalist specialty was not a part of the list of physicians. Hospitalists work as primary care providers specializing in inpatient medicine. They play a significant role, coordinating with specialist physicians and other healthcare professionals. As a caregiver, they provide quality hospital care and boosts efficiency through effective hospital resource allocation. And so, how can we let their presence go overlooked? Our research aimed to bring out their actual numbers before the industry. That is why our research team came up with the research and market study to fetch real facts.

Response: n 2017, the results from the much-awaited Canakinumab Anti-inflammatory Thrombosis Outcome Study (CANTOS) trial were published, confirming the inflammatory hypothesis, i.e. that targeting inflammation can reduce cardiovascular disease. The trial tested the monoclonal antibody canakinumab in a population of post-myocardial infarction patients with elevated inflammation markers (hs-CRP). Canakinumab is currently used for rare diseases and carries an orphan drug price: the 150mg dose used in CANTOS costs approximately $73,000 per year. Due to the high prevalence of cardiovascular disease, millions of patients could potentially be eligible for treatment with this high-priced anti-inflammatory drug. Therefore, we wanted to investigate the cost-effectiveness for canakinumab for secondary prevention of cardiovascular disease, using the reported results from CANTOS.
Author Interviews, Cannabis, University of Michigan / 17.01.2019

MedicalResearch.com Interview with: [caption id="attachment_46988" align="alignleft" width="175"]Daniel J. Kruger, PhD Research Assistant Professor University of Michigan Dr. Kruger[/caption] Daniel J. Kruger, PhD Research Assistant Professor University of Michigan MedicalResearch.com: What is the background for this study? Response: We study health-related behaviors, such as diet and the consumption of caffeine and alcohol. Given the recent trends in legalization of cannabis for medical and even recreational purposes, we were concerned with the narrow focus of current public health efforts regarding cannabis. Although some in the field take a harm-reduction approach to substance use, too many efforts focus solely on abstinence. These programs are a legacy from the era of prohibition, and we know that there are disadvantages to such a restricted scope in public health. For example, municipalities that eliminated or blocked accurate and effective sex education had increases in teenage pregnancy rates. There are so many public health-related aspects of cannabis, beyond risks and adverse effects, which need to be addressed by systematic scientific research. Because of the legal history of cannabis, there is little integration with the mainstream health care system. The focus of the current study was investigating how medical cannabis users perceived medical cannabis in comparison to pharmaceutical drugs and other aspects of the mainstream health care system and how they navigated they relationships between these currently separate systems
Author Interviews, Genetic Research, University of Pennsylvania / 16.01.2019

MedicalResearch.com Interview with: [caption id="attachment_46984" align="alignleft" width="110"]Arslan Zaidi PhD University of Pennsylvania Dr. Zaidi[/caption] Arslan Zaidi PhD University of Pennsylvania and Kateryna Makova, Ph.D. Francis R. and Helen M. Pentz Professor Director, Center for Medical Genomics Department of Biology Penn State University University Park, PA 16802 MedicalResearch.com: What is the background for this study? Response: Mitochondria are organelles that are involved in vital functions in eukaryotic cells, e.g., energy production. Even though they carry their own DNA (mitochondrial DNA, or mtDNA), most of the proteins required for mitochondrial function are encoded by the nuclear genome. Thus, mitochondrial and nuclear proteins must work together in a coordinated manner for proper mitochondrial function. These interactions can sometimes be disrupted leading to phenotypic consequences in inter-species and inter-population laboratory crosses of model organisms when the ancestry of the mitochondrial genome is very different from the nuclear genome. While human populations are genetically not very different from each other, it has been suggested that recent admixture between geographically distant populations might also have phenotypic consequences in humans. We investigated whether there is evidence for this in six different recently admixed populations from the Americas.

Traverse, MD, FACC, FAHA Director of Research Minneapolis Heart Institute Foundation Associate Professor of Medicine Cardiovascular Division University of Minnesota School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Reperfusion injury may contribute a significant amount to final infarct size in setting of ST-elevation myocardial infarction (STEMI). Several studies from Europe and Asia have suggested that modifying reperfusion with an angioplasty balloon of an occluded artery called postconditioning can reduce infarct size. However, not all studies show a benefit. We hypothesized that patient selection of STEMI patients could contribute to these inconsistent findings so we performed the first postconditioning study in the US sponsored by the NIH using the strictest enrollment criteria of any study to minimize factors that influence infarct size (ischemic time, collaterals, pre-infarction angina, TIMI 0 flow) designed to maximize the benefit of postconditioning to see if it can actually reduce infarct size.

Costello MBBS Inflammatory Bowel Disease Service, Department of Gastroenterology The Queen Elizabeth Hospital Australia MedicalResearch.com: What is the background for this study? Response: Ulcerative colitis (UC) is an inflammatory bowel disease that has high rates of persistent or relapsing symptoms despite available therapies. Many of these therapies also have the potential for unacceptable side effects including allergy, intolerance, serious infection and malignancy due to long-term immunosuppression. It is for these reasons that new therapies for Ulcerative colitis are required; particularly therapies that target novel pathways and are not immune suppressing.

What are the main findings? Response: As a dermatologist, we see many patients with newly diagnosed with bullous pemphigoid (BP), many of whom have diabetes. The use of DPP-4 inhibitors is a common treatment for diabetes, we have noted previous case reports that DPP-4 inhibitors may be the cause of BP. For this reason, we started this study. The most important thing in my article is DPP-4 inhibitors, particularly vildagliptin, may be associated with the development of bullous pemphigoid in male patients with diabetes. We have confirmed these points based on the nationwide, population-based study. It is very meaningful because there have been few studies using large sample sizes so far.

What are the main findings? Response: Pediatric solid organ transplant recipients are at increased risk for vaccine preventable infections due to life-long immunosuppressive medications.  The objectives of this study were to 1) evaluate in pediatric    solid organ transplant recipients the number of hospitalizations for vaccine-preventable infections in the first five years post-transplantation and 2) determine the associated morbidity, mortality and costs. In this multicenter cohort study of 6980 children who underwent solid organ transplantation from January 1, 2004, to December 31, 2011, at a center participating in Pediatric Health Information System (PHIS), 15% of individuals had at least 1 hospitalization for a vaccine-preventable infection in the first 5 years after transplant.  Children who received transplants when they were younger than 2 years and recipients of lung, intestine, heart, and multi-visceral organs were at increased risk for hospitalization with a vaccine-preventable infection.  Transplant hospitalizations complicated by a vaccine-preventable infection were $120,498 more expensive (median cost) and were on average 39 days longer than transplant hospitalizations not complicated by vaccine-preventable infections

Response: Group B Streptococcus (GBS) is a leading cause of serious illness such as meningitis and sepsis in infants. Among infants, there are two main types of GBS disease. Early-onset GBS disease occurs during the first week of life and late-onset GBS disease occurs from the first week through three months of life. Rates of early-onset disease in the United States have decreased significantly since the 1990s through widespread implementation of intrapartum antibiotic prophylaxis (IAP) guidelines. However, IAP does not prevent late-onset disease. Maternal immunization represents a nonantibiotic strategy to prevent both early and late-onset disease. Multivalent polysaccharide-protein conjugate vaccines are under development against GBS capsular types, with candidate vaccines in phase I and II trials. Active Bacterial Core surveillance (ABCs) conducts active surveillance for early and late-onset GBS disease among infants in select counties of 10 states, covering about 10% of live births across the United States. We analyzed data from early and late-onset GBS cases identified from ABCs between 2006 and 2015 to describe their epidemiology, incidence trends, and associated strain characteristics.

What are the main findings? Response: The prevalence of young onset diabetes (YOD) is increasing world-wide with doubling of its prevalence in the last 10 years in many developed nations. Using the Hong Kong Diabetes Register established since 1995, we first reported that 1 in 5 Chinese adults with diabetes were diagnosed before the age of 40 years. These young patients had poor control of multiple risk factors with 1.5 fold higher risk of premature death and cardiovascular-renal complications compared to patients with usual onset of diabetes after the age of 40 (Chan JC et al AJM 2014, Luk A et al Diabetes Care 2014). Due to the multisystem nature of diabetes, we asked the question whether these young patients might have recurrent hospitalizations during their 3-4 decades of complex clinical course. Using a territory-wide diabetes database involving 0.42 million people followed up between 2002 and 2014, we compared the hospitalization rates accrued till the age of 75 years and found that patients with young onset diabetes had the highest hospitalization rates by attained age. Compared to patients with usual onset of diabetes, patients with YOD had 1.8- 6.7 higher risk of hospitalizations due to all-causes, notably renal disease compared to those with usual onset of disease. Amongst patients with young onset diabetes, over one-third of the bed-days were due to mental illness before the age of 40 years. We used mathematical modeling and estimated that intensified risk factor control in YOD can reduce the cumulative bed-days by 30% which can be further reduced by delaying the onset of diabetes. These original data is a wakening call to the community regarding the complex nature of YOD involving interactions amongst environment, lifestyles and personal factors (e.g. genetics, education and socioeconomic status) and the biomedical-psychological-behavioral needs of these high risk population, which if undiagnosed, untreated or suboptimally managed, can have huge economic impacts on health care system and loss of societal productivity, leaving personal suffering aside.

What are the main findings? Response: I found that when I was referred women with midurethral sling complications, they were often quite emotional and described a significant period of time when they struggled with the complications before they were referred to someone to assess them. The study looked at the rate of depression and self-harm behavior of women who had surgery for midurethral sling complications compared to women who did not have midurethral sling complications. I found that there was an increased risk of both of these outcomes among women who had surgery for complications, however this risk was primarily present in younger women.

Ordovás, PhD Director Nutrition and Genomics Professor Nutrition and Genetics JM-USDA-HNRCA at Tufts University Boston, MA 02111 MedicalResearch.com: What is the background for this study? Response: The current knowledge supports the notion that poor sleep is associated with cardiovascular risk factors such as obesity, hypertension, and diabetes. Besides, there is some proof that poor sleep might be related to the development of atherosclerosis; however, this evidence has been provided by studies including few participants and, in general, with sleep disorders, such as sleep apnea. Our research has used state-of-the-art imaging technology to measure plaque buildup in the arteries, and objective measures of sleep quantity and quality in about 4000 participants of the PESA CNIC- Santander Study. Moreover, this is the first study to look at the multiterritory development of plaques versus other studies that looked exclusively at the coronary arteries. Therefore, this combination provides stronger evidence than previous studies about the risk of poor sleep on the development of atherosclerosis.

House Staff, Department of Ophthalmology Chang Gung Memorial Hospital Chang Gung University, School of Medicine MedicalResearch.com: What is the background for this study?   Response: More and more patients suffered from diabetes mellitus (DM) around the world, as well diabetic complications such as diabetic retinopathy (DR). DR is one of the major causes of blindness in working-age adults. In addition to the cost of treatment for patients with advanced DR, loss of visual function also yields a great burden to the family and society. For advanced DR, surgical interventions such as retinal laser, intravitreal injection, and vitrectomy are needed. However, those surgical interventions for severe DR can only retard or stop disease progression. If DR can be prevented or slowed by medical treatments, the burden of medical costs for treating severe DR may be decreased. Statin, an HMG-CoA reductase inhibitor, was discussed frequently in the recent years. Multiple functions of statins besides their lipid lowering effect were discovered. Previous investigations have reported that statin therapy could reduce mortality rate and decrease risk of cardiovascular diseases. In our study, we wanted to figure out if statin therapy may have any association between diabetic retinopathy.

Lucey, MD, MSCI Assistant Professor of Neurology Director, Sleep Medicine Section Washington University School of Medicine Saint Louis, Missouri 63110 MedicalResearch.com: What is the background for this study? Response: Alzheimer’s disease and sleep are currently thought to have a two-way or bidirectional relationship. First, sleep disturbances may increase the risk of developing AD. Second, changes in sleep-wake activity may be due to Alzheimer’s disease pathology and our paper was primarily focused on this aspect of the relationship.    If sleep changes were a marker for AD changes in the brain, then this would be very helpful in future clinical trials and possibly screening in the clinic.

MedicalResearch.com Interview with: Yssra-SolimanYssra S. Soliman, BA Division of Dermatology, Department of Internal Medicine Albert Einstein College of Medicine Bronx, New York MedicalResearch.com: What is the background for this study? What are the main findings?  Response: As the population of the United States becomes increasingly diverse, certain fields within medicine have not followed this trend. Dermatology is the least diverse field after orthopedics. We wanted to understand what barriers prevent medical students from applying to dermatology and whether these barriers differed based on students' racial, ethnic or socioeconomic backgrounds. The main findings of this study are that certain groups are more likely to cite specific barriers than non-minority students. These barriers are significant deterrents to applying to dermatology and include the lack of diversity in dermatology, negative perceptions of minority students by residency programs, socioeconomic barriers such as lack of loan forgiveness and poor accessibility to mentors.

What are the main findings? Response: It is well known that maternal obesity increases risks of adverse fetal outcomes, including congenital malformations of the heart. However, it is unclear if maternal overweight and obesity associate with risks of specific and more complex congenital heart defects. We conducted a population-based cohort study in Sweden using data from several health registries. The study included more than 2 million live, singletons born between 1992-2012. Risks (prevalence rate ratios) of complex heart defects (Tetralogy of Fallot, transposition of the great arteries (TGA), atrial septal defects (ASD), aortic arch defects, and single ventricle heart) and several specific heart defects were estimated in infants to mothers with overweight and increasing degree of obesity. We found that risks of aortic arch defects, ASD and patent ductus arteriosus (in term infants) increased with maternal obesity severity. On the other hand, we found no clear associations between maternal BMI and risks of several other complex and specific heart defects.

Response: Typhoid fever is a life-threatening disease caused by Salmonella Typhi bacteria. It spreads when someone consumes food or water that has been contaminated with feces (poop) from someone carrying the bacteria. About 12–27 million cases of typhoid fever occur worldwide every year. About 350 culture-confirmed cases of typhoid fever in the United States are reported to CDC each year. Most of these cases occur among international travelers. Symptoms of typhoid fever often include high fever, weakness, stomach pain, cough, and loss of appetite. Some people have diarrhea or constipation. Typhoid fever can be prevented through vaccination and safe food and water practices. Typhoid fever is treated with antibiotics, although most infections diagnosed in the United States cannot be successfully treated with the class of antibiotics called fluoroquinolones.

Birnbaum, Ph.D. Associate Professor Baruch Ivcher School of Psychology Interdisciplinary Center (IDC) Herzliya Herzliya, Israel Dr. Birnbaum[/caption] Gurit E. Birnbaum, Ph.D. Associate Professor Baruch Ivcher School of Psychology Interdisciplinary Center (IDC) Herzliya Herzliya, Israel  MedicalResearch.com: What is the background for this study? Response: Sexual desire evolved to serve as a powerful motivational force that brings potential romantic partners together initially and thereby helps to facilitate sexual intercourse and pregnancy. As such, sexual acts may be devoid of affectional bonding, as in the case of one night stands. And yet, sexual desire may play a major role not only in attracting potential partners to each other, but also in encouraging the formation of an attachment between them. Nevertheless, thus far it has been unclear whether desire motivates merely reproductive acts, with attachment between partners developing independently, or whether desire directly contributes to the building of an emotional bond between newly acquainted partners. Indeed, although sexual urges and emotional attachments are not necessarily connected with each other, evolutionary and social processes may have rendered humans particularly likely to become romantically attached to partners to whom they are sexually attracted. The present research sought to provide support for the latter option.

There are different preparations of hormones available for such women.  Some of them were extensively studied in a large American Trial Women’s Health Initiative and showed the risk of VTE to be twice as high for women who took them.  However, these well-studied drugs are mostly prescribed in America.  The more popular drugs in Europe and the UK have been much less studied, so it was unclear how they compared.

Response: Patients requiring surgery for esophageal cancer fare better after undergoing a hybrid minimally invasive esophagectomy (HMIE) with a combined laparoscopy+thoracotomy procedure compared to an open esophagectomy (OE), according to results of the MIRO trial published in the last issue of the New England Journal Of Medicine (link article). This French prospective multi-center randomized controlled study was funded by the French National Cancer Institute (Grant n° 1907). The study was conducted by Pr Mariette who sadely passed away in 2017 and Pr Piessen (Department of Digestive and Oncological Surgery, CHU Lille), under the hauspice of FRENCH (Fédération de Recherche EN Chirurgie) and FREGAT (French Eso-Gastric Tumors) working group (https://www.fregat-database.org/fr/). Postoperative morbidity, especially pulmonary complications, affects more than half of patients after open esophagectomy for esophageal cancer. Hybrid minimally invasive esophagectomy (HMIE) combines a laparoscopic abdominal phase with an open thoracotomy, which may have specific advantages including lower rate of pulmonary complications, without laparoscopic tumor dissection limiting potential tumor spillage and easier reproducibility of the technique [12].

What are the main findings? Response: Recent research has demonstrated the importance that neighborhood context has on life opportunity, health and well-being that can perpetuate across generations. A strongly defining factor that leads to differences in health outcomes across neighborhoods, such as differences in chronic disease, is the concurrent-uneven distribution of modifiable risk factors for chronic disease. The main goal of our study was to characterize inequities in smoking, the leading risk factor for chronic disease, between neighborhoods in America's 500 largest cities. To accomplish this aim we used first-of-its-kind data generated from the 500 Cities Project—a collaboration between Robert Wood Johnson Foundation and the US Centers for Disease Control and Prevention—representing the largest effort to provide small-area estimates of modifiable risk factors for chronic disease. We found that inequities in smoking prevalence are greater within cities than between cities, are highest in the nation’s capital, and are linked to inequities in chronic disease outcomes. We also found that inequities in smoking were associated to inequities in neighborhood characteristics, including race, median household income and the number of tobacco retailers.

MedicalResearch.com Interview with: [caption id="attachment_46889" align="alignleft" width="132"]Dr. Venkatakrishna R Jala, PhD Assistant Professor James Graham Brown Cancer Center Department of Microbiology and Immunology University of Louisville Dr. Jala[/caption] Dr. Venkatakrishna R Jala, PhD Assistant Professor James Graham Brown Cancer Center Department of Microbiology and Immunology University of Louisville MedicalResearch.com: What is the background for this study? What are the main findings? Response: Humans evolved along with their gut microbiota and adapted their physiological activities to help each other. Along with consumption of healthy diets, humans must harbor the appropriate microbiota to convert the foods into available components called metabolites. These microbial metabolites play a critical role in preserving homeostasis, the development of immune systems and preventing adverse events both systemically and locally. Despite the availability of large metagenomics (bacterial sequence) data, and its associations with disease conditions, the functional dynamics of microbiota (good vs bad) in human health or diseases are yet to be defined. The host’s indigenous gut microbiota and its metabolites have emerged as key factors that greatly influence human health and disease, including inflammatory bowel diseases (IBD). IBD patients suffer from leaky gut and increased inflammation. The current study demonstrates that a microbial metabolite derived from ellagitannin/ellagic acid rich diets (e.g., pomegranate, berries) called ‘urolithin A’ and its synthetic analogue significantly enhance gut barrier function in addition to blocking the unwarranted inflammation in IBD animal models.

Response: The human gastrointestinal tract (GIT) contains several distinct physical environments within the stomach, small intestine (duodenum, jejunum, ileum) and colon that harbor complex microbial communities. Changes in the fecal microbe composition have been described for Roux-en-Y gastric bypass (RYGB), the most effective and durable treatment for morbid obesity, and sleeve gastrectomy (SG).
