MedicalResearch.com Interview with: [caption id="attachment_57600" align="alignleft" width="200"]Dr. D'Amico Dr. D'Amico[/caption] Anthony D'Amico, MD, PhD Professor and Chief of Genitourinary Radiation Oncology Brigham and Women's Hospital and Dana-Farber Cancer Institute MedicalResearch.com: What is the background for this study? Response: 3 randomized trials published in Sept, 2020 in the Lancet and Lancet Oncology concluded that delivering radiation therapy (RT) after surgery for prostate cancer   when the PSA rises signaling recurrence (i.e. early salvage RT) as opposed to when the PSA is undetectable (i.e. adjuvant RT) did not compromise subsequent cancer progression. However these trials may have missed the benefit of adjuvant RT because a minority of men (9 to 17% of the study cohorts) were found to have adverse factors at prostatectomy which are associated with cancer progression and death from prostate cancer. Specifically, men with adverse pathology at prostatectomy comprise the vast majority of men who go on to die from prostate cancer and therefore have the most to gain from adjuvant RT. Yet, given the results of the 3 randomized trials many physicians are no longer offering adjuvant RT, even in men with adverse pathology at surgery.

The Hawaii Medical Service Association Endowed Chair Health Services and Quality Research Professor, and Associate Research Director Department of Family Medicine and Community Health University of Hawaii John A. Burns School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Response: Gaining weight during pregnancy is natural but gaining too little or too much weight can be harmful for pregnant people and their babies. For the first time, the Task Force reviewed the evidence and found that counseling pregnant people on healthy weight gain during pregnancy can lower their risk for diabetes during pregnancy, emergency cesarean deliveries, and babies born with a birth weight that is too high. Pregnant people may not know what amount of weight gain is healthy during pregnancy, or how weight gain can affect their pregnancy and baby. We recommend that clinicians offer all pregnant people counseling on healthy weight gain throughout their pregnancy for healthier, safer pregnancies.

MedicalResearch.com Interview with: Haley Steele Graduate Student Researcher Georgia Institute of Technology  MedicalResearch.com: What is the background for this study? Response: Chronic itch is a debilitating symptom that arises from a broad range of etiologies including skin disease, systemic disease, and as a common side-effect of medication. While in the last few decades significant advances in our understanding of the mechanisms underlying chronic itch have been made, a large majority of those advancements were restricted to studies in hairy skin. Conditions such as plantar and palmar psoriasis, dyshidrosis, and cholestasis, however, are known to exhibit chronic itch restricted primarily to glabrous skin (found on the palms of hands and soles of feet). This is an area that is considered to be particularly debilitating. Therefore, in this study we investigated the role three previously identified pruriceptive neurons (MrgprA3+, MrgprD+, and MrgprC11+) play in mediating acute and chronic glabrous skin itch.

MedicalResearch.com Interview with: Daimei Sasayama, M.D., Ph.D. Department of Psychiatry Shinshu University MedicalResearch.com: What is the background for this study? Response: The diagnosis of autism spectrum disorder (ASD) is increasing worldwide. A 2016 US survey reported a prevalence of 1.85% in 8-year-olds, and a birth cohort study in Denmark reported that the future cumulative incidence of ASD could exceed 2.8%. Our recent regional cohort study in Japan reported an even higher cumulative incidence of 3.1%. So we examined whether the cumulative incidence in our regional cohort represents the nationwide incidence in Japan.

MedicalResearch.com Interview with: [caption id="attachment_57486" align="alignleft" width="133"]Martha Kubik, Ph.D., R.N. Professor and Director School of Nursing College of Health and Human Services George Mason University Dr. Kubik[/caption] Martha Kubik, Ph.D., R.N. Professor and Director School of Nursing College of Health and Human Services George Mason University MedicalResearch.com: What is the background for this study? Response: Colorectal cancer is the third leading cause of cancer deaths in the United States, yet about a quarter of people ages 50 to 75 have never been screened for this devastating disease. Fortunately, we know that screening for colorectal cancer is effective and saves lives. New science about colorectal cancer in people younger than 50 years old has enabled us to expand our previous guidelines to recommend that all adults ages 45 to 75 be screened for colorectal cancer to reduce their risk of dying from this disease.

Severinghaus Assistant Professor In Residence Anesthesia & Perioperative Care UCSF Medical Center Dr. Whitlock[/caption] Elizabeth L. Whitlock, MD, MSc John W. Severinghaus Assistant Professor In Residence Anesthesia & Perioperative Care UCSF Medical Center MedicalResearch.com: What is the background for this study? Response: We have known for a while that, rarely, some older adults suffer substantial, durable cognitive decline after surgery, particularly after coronary artery bypass grafting (CABG) surgery; a larger proportion experience a decline in cognitive test performance which doesn't necessarily affect function, but which has caused concern among researchers.  This cognitive decline was attributed, in part, to the cardiac bypass pump. ​Many of the studies had methodological limitations which made it difficult to be sure that the cognitive change was due to surgery and not due more generally to heart problems or atherosclerotic disease, which may also imply cerebrovascular atherosclerosis. Using a large database of older adults who undergo regular cognitive testing, we identified individuals who underwent CABG and compared them to those who underwent percutaneous coronary intervention (PCI), a minimally invasive, non-surgical method of opening blocked coronary arteries.  This allowed us to model the rate of memory decline before surgery - which hadn't been done in previous studies - and compare it to the rate of memory decline after surgery in older adults who had serious heart disease (some of whom were treated with CABG, and some treated with PCI).

Carlson Ph.D. Associate Dean for Research Program Director,, AJ Rice Professor Department of Dietetics and Nutrition University of Kansas Medical Center Kansas City, KS MedicalResearch.com: What is the background for this study? What are its benefits? Response: DHA is an omega-3 fatty acid. Good food sources include some types of seafood (e.g., salmon, tuna, trout) and chicken eggs. Persons in the USA and in much of the developing world consume little dietary DHA. DHA supplements in pregnancy have been linked to lower risk of preterm birth for 20 years, especially early preterm births (<34 weeks gestation). For about 10 years, prenatal supplements with about 200 mg DHA have been readily available in the USA, however, no study has asked if this amount of DHA is optimal to reduce early preterm birth. Participants were given a supplement of 1000 mg or 200 mg DHA beginning before 20 weeks gestation using an adaptive randomization that periodically assigned more participants to the group with the fewest early preterm births.

MedicalResearch.com Interview with: [caption id="attachment_57322" align="alignleft" width="200"]Michael S. Garshick, MD Assistant Professor Department of Medicine Grossman School of Medicine NYU Dr. Garshick[/caption] Michael S. Garshick, MD Assistant Professor Department of Medicine Grossman School of Medicine NYU MedicalResearch.com: What is the background for this study? Response: Patients with psoriasis have a 50% higher risk of cardiovascular disease when compared to patients without psoriasis, the mechanisms of which are still under investigation Dyslipidemia is also highly prevalent in psoriasis including elevation in a variety of lipoproteins causal in atherosclerosis. Lipoprotein(a) is an LDL like particle which is associated with atherosclerosis, atherothrombosis, and the development of clinical cardiovascular disease. Traditionally lipoprotein(a) is felt to be inherited rather than acquired, but some evidence suggest that lipoprotein(a) is elevated in those with underlying inflammatory conditions and associated with systemic inflammation including circulating IL-6. We therefore aimed to determine if lipoprotein(a) is elevated in psoriasis and associated with underlying systemic inflammatory profiles and biomarkers of cardiovascular risk.

In cohort analyses of racial and ethnic groups from the previous three decades, Black patients were constantly at a higher risk of mortality after cardiac transplantation. In 2018, the United Network for Organ Sharing (UNOS) revised the allocation system to expand access to organs for the most medically urgent patients and reduce disparities and regional differences. We sought to evaluate contemporary trends and impact of the new 2018 allocation system.

Response: Non-Hispanic African American women experience a disproportional burden of poor breast cancer outcomes than non-Hispanic White women, which is associated with a higher incidence of triple-negative breast cancer (TNBC), more advanced stages at diagnosis, and lower treatment adherence. However, the differences in clinical treatment and outcomes between African American women with TNBC and their White counterparts have not been well defined.
Author Interviews, COVID -19 Coronavirus, Heart Disease, JACC, Social Issues / 12.05.2021

MedicalResearch.com Interview with: [caption id="attachment_57355" align="alignleft" width="150"]Kobina Hagan MBBS, MPH Postdoctoral Fellow Center for Outcomes Research, Houston Methodist Research Institute Dr. Hagan[/caption] Kobina Hagan MBBS, MPH Postdoctoral Fellow Center for Outcomes Research, Houston Methodist Research Institute MedicalResearch.com: What is the background for this study? Response: Before the COVID-19 vaccination roll-out, risk mitigation guidelines including respiratory hygiene, social distancing, and job flexibility, were the most effective preventive measures against coronavirus transmission. Social determinants of health scholarships had identified social circumstances to limit adherence to these mitigation guidelines. Individuals with underlying cardiovascular disease are identified as high-risk phenotypes for severe COVID-19 outcomes. In addition, research efforts during the early and middle waves of the pandemic had identified coronavirus exposure risk as a greater mediator of the observed COVID-19 disparities, compared to clinical susceptibility from comorbidities. Yet, population-based evidence on the practice of these mitigation guidelines in this high-risk group were lacking. Consequently, we believed there was a need to robustly characterize COVID-19 risk mitigation practices among adults with cardiovascular disease in the nation. The COVID-19 Household Impact Survey was a survey conducted by the National Opinion Research Center at the University of Chicago, to provide statistics about health, economic security, and social dynamics of the US adult household population nationwide and for 18 geographic areas (10 states, 8 metropolitan statistical areas) between April and June 2020. This survey complemented the Household Pulse Survey by the Census Bureau. In this study we described the COVID-19 risk mitigation practices among patients with CVD and evaluated the association between cumulative social determinants of health burden (a measure of social adversity) and adherence these measures.

MedicalResearch.com Interview with: [caption id="attachment_57388" align="alignleft" width="150"]Kenechukwu Ndubisi Mezue, M.D Fellow in Nuclear Cardiology  Massachusetts General Hospital Dr. Mezue[/caption] Kenechukwu Ndubisi Mezue, M.D Fellow in Nuclear Cardiology  Massachusetts General Hospital MedicalResearch.com: What is the background for this study? Response: Observational studies have shown that moderate alcohol intake may have beneficial effects on cardiovascular disease. However, the mechanisms through which this benefit occurs is mostly unknown. Chronic stress is also known to associate with increased risk of cardiovascular disease and our group has shown in previous work that increased activity in the stress-associated regions of the brain (such as the amygdala) is significantly associated with increased bone marrow activity, arterial inflammation, and cardiovascular events. Our current study hypothesizes that moderate alcohol intake reduces cardiovascular events by reducing chronic stress-associated brain activity.

Wong, M.D. Chief Scientific Officer Vice chair for Clinical Affairs Chief of the Division of Clinical Decision Making and Primary care Clinician Department of Medicine at Tufts Medical Center   MedicalResearch.com: What is the background for this study? Response: Hypertension affects nearly half of all adults in the United States and is a major risk factor for many serious health conditions. Fortunately, by screening all adults for hypertension, clinicians can improve their patient’s health. The Task Force continues to recommend screening all adults for hypertension so that they can get the care they need to help prevent health conditions such as heart attack, stroke, and kidney failure.

MedicalResearch.com Interview with: Isaac See, MD Centers for Disease Control and Prevention COVID-19 Response Team Atlanta, Georgia MedicalResearch.com: What is the background for this study? Response: On February 27, 2021 the U.S. Food and Drug Administration (FDA) granted emergency use authorization for the Janssen/Johnson & Johnson (J&J) COVID-19 Vaccine in people 18 years of age or older in the United States.  The Janssen/J&J COVID-19 Vaccine uses a replication-deficient (i.e., cannot cause infections) human adenovirus vector.  In mid-March, the European Medicines Agency announced that they had conducted a preliminary investigation of cases of blood clots and low counts of blood cells called platelets in patients who had recently received the Oxford/AstraZeneca COVID-19 Vaccine, which uses a replication-deficient chimpanzee adenovirus vector.  This syndrome of blood clots and low platelet counts has been called thrombosis with thrombocytopenia syndrome, or TTS.  The European investigation showed that over 70% of their cases specifically involved blood clots in particular veins inside the brain, a condition caused cerebral venous sinus thrombosis (CVST), in addition to low platelet counts (thrombocytopenia is the medical term for low platelet counts). CVST is already a rare condition, and CVST with thrombocytopenia is even rarer.  By April 12, 2021, approximately 7 million doses of the Janssen/J&J COVID-19 Vaccine had been given in the United States, and six cases of CVST and thrombocytopenia after receipt of the Janssen/J&J COVID-19 Vaccine had been reported to the U.S. Vaccine Adverse Event Reporting System (VAERS), which is the U.S. national vaccine safety monitoring system.  The next day (April 13, 2021) CDC and FDA recommended a pause in use of the vaccine recommended to allow for further investigation of these events.  On April 23, 2021 data about the first 12 cases reported after authorization of the Janssen/J&J COVID-19 Vaccine were presented at an emergency meeting of the Advisory Committee on Immunization Practices (ACIP) to decide what to recommend regarding the Janssen COVID-19 vaccine.  The ACIP concluded that the benefits of resuming Janssen COVID-19 vaccination among persons aged 18 years or older outweighed the risks and reaffirmed its interim recommendation under the FDA’s Emergency Use Authorization.  The FDA’s Emergency Use Authorization includes a new warning for rare clotting events among women aged 18 to 49 years. Our report provides clinical details about these first reported 12 U.S. cases of CVST and thrombocytopenia following receipt of the Janssen COVID-19 Vaccine.

Durgan, PhD Department of Anesthesiology Baylor College of Medicine Houston, TX Dr. Durgan[/caption] David J. Durgan, PhD Department of Anesthesiology Baylor College of Medicine Houston, TX  MedicalResearch.com: What is the background for this study? Response: Our lab and others had previously shown that gut dysbiosis is not only associated with hypertension, but actually plays a causal role. For example we have shown in both a genetic model of hypertension as well as an obstructive sleep apnea induced model of hypertension, that transplantation of their dysbiotic microbiota into normotensive recipients induced elevations in blood pressure. With this understanding our focus shifted to two new questions 1) How can we manipulate the microbiota to improve/prevent hypertension, and 2) What are the signals originating from the microbiota that have the capability to influence host blood pressure? These questions lead to the experimental design of this study.

MedicalResearch.com Interview with: [caption id="attachment_57270" align="alignleft" width="176"]Yun Liu, PhD Google Health Palo Alto, California Dr. Yun Liu[/caption] Yun Liu, PhD Google Health Palo Alto, California MedicalResearch.com: What is the background for this study? Would you describe the system?  Does it use dermatoscopic images? Response: Dermatologic conditions are extremely common and a leading cause of morbidity worldwide. Due to limited access to dermatologists, patients often first seek help from non-specialists. However, non-specialists have been reported to have lower diagnostic accuracies compared to dermatologists, which may impact the quality of care. In this study, we built upon prior work published in Nature Medicine, where we developed a computer algorithm (a deep learning system, DLS) to interpret de-identified clinical images of skin conditions and associated medical history (such as whether the patient reported a history of psoriasis). These clinical images are taken using consumer-grade hardware such as point-and-shoot cameras and tablets, which we felt was a more accessible and widely-available device compared to dermatoscopes. Given such images of the skin condition as input, the DLS outputs a differential diagnosis, which is a rank-ordered list of potential matching skin conditions. In this paper, we worked with user experience researchers to create an artificial intelligence (AI) tool based on this DLS. The tool was designed to provide clinicians with additional information per skin condition prediction, such as textual descriptions, similar-appearing conditions, and the typical clinical workup for the condition. We then conducted a randomized study where 40 clinicians (20 primary care physicians, 20 nurse practitioners) reviewed over 1,000 cases -- with half the cases with the AI-based assistive tool, and half the cases without. For each case, the reference diagnosis was based on a panel of 3 dermatologists.

What are the main findings? Response: Complete skin clearance is an important treatment goal for patients with psoriasis and is closely associated with treatment satisfaction and improved quality of life. However, it remains an unmet need for many patients. The interleukin (IL)-17 isoforms IL-17A and IL-17F play central roles in psoriasis pathophysiology and are overexpressed in psoriatic tissues. Existing biologic therapies, such as secukinumab, inhibit IL-17A only. However, increasing evidence indicates that IL-17F contributes independently to the pathobiology of plaque psoriasis, and that blocking both IL-17A and IL-17F may lead to more complete suppression of inflammation and superior clinical outcomes, compared with blocking IL‑17A alone. Bimekizumab is a humanized monoclonal IgG1 antibody that has been designed to selectively inhibit IL-17F in addition to IL-17A.

MedicalResearch.com Interview with: Michelle M. Chen, MD/MHS Clinical Lecturer Department of Otolaryngology-Head and Neck Surgery University of Michigan MedicalResearch.com: What is the background for this study? Response: HPV is the most common sexually transmitted infection in the United States and associated with several malignancies including oropharyngeal, cervical, vaginal, vulvar, penile, and anal cancers. In 2020, the FDA expanded the indications for HPV vaccination to include the prevention of oropharyngeal cancer, which is the most common HPV-associated malignancy and about 80% of oropharyngeal cancer patients are male. HPV vaccination rates are closely tracked for adolescents but less is known about vaccination rates for young adults. The goal of our study was to understand HPV vaccinations for young adult men and women, ages 18-21.

Response: Our study was really guided by a key question: does Covid-19 in pregnancy increase the risk of adverse maternal and neonatal outcomes as compared with pregnant women who do not have the infection? The question is highly relevant because of the known deleterious effects of other coronavirus infections in pregnancy, e.g. SARS (severe acute respiratory syndrome) and MERS-CoV (Middle East respiratory syndrome coronavirus). In order to answer this question we undertook this multinational cohort study.

Blankson, MD, PhD Department of Infectious Diseases Associate Professor Cellular and Molecular Medicine Program Johns Hopkins MedicalResearch.com: What is the background for this study? Which vaccines did you evaluate? Response: Prior studies from several groups including our own have found T cell cross-recognition of peptides from SARS-CoV-2 and the common cold coronaviruses. We asked whether as a result of this cross-reactivity, immunization with the SARS-CoV-2 vaccine would also enhance T cell responses to the common cold coronaviruses. Prior studies also suggested that antibodies elicited from the mRNA vaccines had a reduced ability to neutralize the emerging variants of concern. Most of the study participants had received the Pfizer vaccine, but a few had received the Moderna vaccine.

What are the main findings? Response: Vitamin D is an important nutrient for keeping bones healthy, and it may also have a role in other aspects of good health. However, we do not have enough evidence to understand what levels of vitamin D people need to keep them healthy or what levels are too low. As a result, the Task Force determined there is not enough evidence to recommend for or against screening for vitamin D deficiency in adults who do not have signs or symptoms. It is our hope that with more research, we will be able to make a strong, evidence-based recommendation on screening for vitamin D deficiency in the future.

Response: Triple negative breast cancer (TNBC) represents an aggressive subtype of breast cancer associated with guarded prognosis. For patients with pre-treated metastatic TNBC, standard chemotherapy is associated with low response rate (5-10%) and poor progression-free survival (2-3 months), highlighting need for better therapies. Sacituzumab govitecan is an antibody drug conjugate (ADC) which  combines SN-38, an active metabolite of irinotecan, with an antibody against Trop-2, an antigen overexpressed in majority of triple negative breast cancer.

MedicalResearch.com Interview with: [caption id="attachment_57196" align="alignleft" width="200"]Efrat Monsonego Ornan, Ph.D  Head of School of Nutritional Sciences Institute of Biochemistry and Nutrition  The Robert H. Smith Faculty of Agriculture,  Food and Environment  The Hebrew University of Jerusalem Prof. Monsonego Ornan[/caption] Efrat Monsonego Ornan, Ph.D  Head of School of Nutritional Sciences Institute of Biochemistry and Nutrition The Robert H. Smith Faculty of Agriculture, Food and Environment The Hebrew University of Jerusalem MedicalResearch.com: What is the background for this study? Response: Food supplies in recent decades have been dominated by heavily processed, ready-to-eat products. Essentially, 75% of all world food sales are of processed foods. Over the past 30 years, children’s ultra-processed food intake has increased markedly, with 50% of the children in the US consuming these foods. Only in the US does UPF comprise 58% of energy intake, of which 90% is derived from added sugars. This reflects children’s excessive consumption of food and drink that are high in fat and refined sugars but do not provide appropriate levels of the proteins, vitamins and minerals required for growth. The negative health outcomes of excessive consumption of Ultra-processed food are well known, include obesity, metabolic syndrome and diabetes, and considered as the current world epidemic; the fact that children, during their postnatal development period (birth to adolescent), are the target of the Ultra-processed food industry is very disturbing in terms of public health. Bone development and growth are the characteristic phenomena of the childhood period. Yet, in spite of the huge importance of nutrition to bone development, the impact of Ultra-processed food consumption on skeleton development during childhood has never been studied directly, and this was the purpose of our study. To this end, we used young rats which are an excellent pre-clinical model for growth and fed them with either the recommended diet for their age or  a diet comprised of a typical Ultra-processed meal (a roll, hamburger, tomatoes, lettuce, ketchup and French fries) and a caloric soft drink.

Response: Clinician burnout rates have hovered around 50% for much of the past decade.  Burnout is a significant concern in healthcare for its effects on care givers and associated downstream adverse implications on patient care for quality and safety. The ubiquitous presence of Electronic Health Records (EHR) along with the increased clerical components and after hours use has been a significant concern for contributing to provider burnout.

Response: Recently public health officials have recommended doubling masks, although the initial study conducted by CDC investigators  was limited in type and combinations of masks tested, so our study compared fitted filtration efficiency of commonly available masks worn, singly, doubled or in combination. MedicalResearch.com: What are the main findings? Response:  Doubling of masks can improve the fitted filtration efficiency of masks, that is how well masks protect you from inhalation of aerosols from others.
