MedicalResearch.com Interview with: Mario F.L. Gaudino, M.D. PhD Attending Cardiac SurgeonDepartment of Cardiothoracic Surgery Antonino Di Franco, MD Adjunct Clinical Assistant Professor of Cardiothoracic Surgery Weill Cornell Medicine   MedicalResearch.com:  What is the background for this study?  What is the aim of this review?  Response: Biological and socio-cultural differences between men and women are complex and likely account for most of the variations in the epidemiology and treatment outcomes of coronary artery disease (CAD) between the two sexes. Despite the growing recognition of sex-specific determinants of outcomes, representation of women in clinical studies remains low, and sex-specific management strategies are generally not provided in guidelines. We summarized the current evidence on sex-related differences in patients with CAD, focusing on the differential outcomes following medical therapy, percutaneous coronary interventions, and coronary artery bypass surgery.

MedicalResearch.com Interview with: Dorothy Klimis-Zacas, MS, PhD, FACN Professor of Clinical Nutrition School of Food and Agriculture Graduate Faculty School of Biomedical Sciences Associate Faculty, Institute of Medicine Fulbright Fellow University of Maine Orono, Maine 04469  MedicalResearch.com:  What is the background for this study?  Response: Bioactive compounds such as polyphenols have been documented to have wound healing properties . In the Klimis-Zacas laboratory, phenolic extracts (PE) from wild blueberries (WB) were reported to promote angiogenesis in HUVEC cells via cell migration, angiogenesis, through VEGF/P13K/AKT pathway documented that the PE, primarily composed of chlorogenic acid significantly promoted cell migration and closure speed of wound by 38% above the control as well as angiogenesis and gene expression for proteins critical for cell movement while the anthocyanin fraction inhibited the above processes (5,6).  (more…)
Author Interviews, Blood Pressure - Hypertension, Cognitive Issues / 05.04.2022

MedicalResearch.com Interview with: Dr. Yangfeng Wu Peking University Clinical Research Institute Peking University MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: It is well-established that elevated blood pressure (BP) at single time point can contribute to increased risks of suffering accelerated cognitive decline, dementia, and mortality. Nevertheless, BP levels could experience significant alterations as time goes, indicating the necessity of monitoring BP longitudinally. In other words, using blood pressure levels measured at baseline to predict future outcomes in a longitudinal cohort with a long-term follow-up period ≥20 years, becomes controversial. Cumulative BP levels have been indicated as a feasible approach for evaluating long-term exposure of BP levels, which might have the ability to respond to this controversy. This is the main reason why we performed this research to evaluate the predictive values of cumulative BP levels, especially additional values beyond baseline blood pressure levels, for future neurocognitive and longevity outcomes.

Author Interviews, Autism, Medical Imaging / 02.04.2022

MedicalResearch.com Interview with: Alpen ORTUĞ, PhD Postdoctoral Research Fellow​ Massachusetts General Hospital Department of Radiology Martinos Center for Biomedical Imaging Boston, MA   MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Finding the earliest diagnosis possible for autism spectrum disorder (ASD) is one of the main goals for researchers studying ASD. This study aimed to investigate the critical abnormalities in prenatal brain development in ASD using structural magnetic resonance imaging (MRI). We hypothesized that volumetric analyses of brain segmentations are useful to identify such abnormalities before birth. We have retrospectively analyzed fetal MRI based on the knowledge that the same individuals were later diagnosed with autism spectrum disorder. We have evaluated developmental abnormalities in brain structures of prospective ASD fetuses using volumetric segmentation. The current study is still preliminary, but the ‘insula’ of the brain showed statistically significant volumetric enlargement in prospective ASD patients, compared to the other three control groups.  (more…)

MedicalResearch.com Interview with: Scott D. Barnes, MD Chief Medical Officer STAAR Surgical https://staar.com/MedicalResearch.com:  What is the background for the EVO procedure?  Would you briefly describe what is meant by myopia and how common it is? Response: EVO is a clinically-proven implantable lens that corrects common vision problems such as nearsightedness and nearsightedness with astigmatism. EVO can be the solution for people who want to get rid of their glasses or contact lenses. Myopia (or nearsightedness) is the most common ocular disorder worldwide and its incidence is increasing significantly. An estimated 30% of the world's population, or 2.6 billion people, have myopia and this number is projected to rise to 50% of the global population by the year 2050. (more…)
Author Interviews, NEJM, OBGYNE, Surgical Research / 31.03.2022

MedicalResearch.com Interview with: Professor Mohamed Abdel-Fattah, MD, FRCOG Chair in Gynaecology Consultant Gynaecologist & Sub-specialist Urogynaecologist School Medicine, Medical Sciences and Nutrition University Of Aberdeen Co-Director Aberdeen Centre For Women’s Health Research Lead – MBChB intercalated degree programme Chief Investigator – CATHETER II, FUTURE, and SIMS RCTs MedicalResearch.com:  Why was this study necessary? Response:At the time of study design, the main surgical option for treating stress urinary incontinence was the insertion of a standard mid-urethral sling, usually using a general anaesthetic. However, single incision mini-slings were introduced to clinical practice without robust assessment. They were considered promising due to several potential advantages including using less mesh more possibility to be performed under local anaesthetic. A number of small studies with short-term follow-up (i.e. low quality evidence) showed mini-slings to have similar success rates to standard mid-urethral slings, but required shorter hospital stay and was less painful immediately after surgery. Several systematic reviews at the time recommended an adequately powered robust randomised trial to compare the clinical and cost-effectiveness of mini-slings to standard mid-urethral slings with adequate term follow-up.  (more…)
Author Interviews, Critical Care - Intensive Care - ICUs, Infections / 29.03.2022

MedicalResearch.com Interview with: Michael J. Mahan Ph.D. Professor Dept of Molecular, Cellular, and Developmental Biology University of California Santa Barbara, CA MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response:  Sepsis is the number one cause of death in US hospitals- but few molecular diagnostics and therapies exist for this condition. In the clinic, sepsis is diagnosed by a symptom-based approach that may include kidney or liver failure, blood clotting or bleeding — which is often well after permanent organ damage. Thus, molecular diagnostics that detect infection at early stages of disease to minimize host injury are sorely needed. (more…)
Allergies, Annals Internal Medicine, Author Interviews, Pharmacology / 29.03.2022

MedicalResearch.com Interview with: Chintan V. Dave, PharmD, PhD Assistant Professor Ernest Mario School of Pharmacy Institute for Health, Health Care Policy and Aging Institute Rutgers University MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: The risks of anaphylaxis among intravenous (IV) iron products currently in use has not been assessed. Older adults have a higher risk of experiencing drug-induced anaphylaxis. Accordingly, our study objective was to elucidate the risk of anaphylaxis  among older adults receiving the five frequently used IV iron products: ferric carboxymaltose, ferumoxytol, ferric gluconate, iron dextran, and iron sucrose.

Author Interviews, HIV / 29.03.2022

MedicalResearch.com Interview with: Shokrollah Elahi PhD Associate Professor at University of Alberta MedicalResearch.com:  What is the background for this study?  Response: CD8+T cells (killer T cells) play an important role against virally infected and cancer cells, however, their functional properties get compromised during the course of HIV infection and cancer. CD73, is one of molecules that influences killer T cell functions but its role in the context of viral infections has not been well defined. In this study, we analyzed the presence of this protein (CD73) on killer T cells in a cohort of 102 HIV-infected individuals. We found that the proportion of killer T cells expressing this protein was substantially lower among different killer T cell subsets obtained from the blood of HIV-infected individuals compared to individuals who were not infected with HIV. Notably, CD73 was decreased at the intracellular protein and gene levels. This suggests that the CD73 gene gets suppressed by a specific mechanism in HIV-infected individuals. Furthermore, we decided to better understand the difference between killer T cells having CD73 versus those who do not. We found that CD73 was essential for the migratory capacity of killer T cells. It means killer T cells without this protein have impaired ability to move into the tissues. This implies that lack of CD73 prevents killer T cells from homing into the tissue where HIV reservoirs are hidden. (more…)
Author Interviews, Brigham & Women's - Harvard, Neurology, Pain Research / 29.03.2022

MedicalResearch.com Interview with: William R. Renthal, MD, PhD Director of Research, John R. Graham Headache Center Department of Neurology Brigham and Women's Hospital Assistant Professor of Neurology, Harvard Medical School MedicalResearch.com:  What is the background for this study?  Response: We know that a nervous system structure called the trigeminal ganglion plays a critical role in migraine headache, but the cell types that exist in this structure are poorly understood. We have used cutting-edge, single-cell genomic technologies to profile the genes expressed within each trigeminal ganglion cell type in both human and mouse with the goal of identifying molecular features that could allow us to inhibit head pain selectively without affecting other cell types.

MedicalResearch.com Interview with: Aaron Drucker MD, ScM, FRCPC Division of Dermatology, Department of Medicine, Women’s College Hospital Scientist, Women’s College Research Institute Assistant Professor, Department of Medicin and Institute of Health Policy, Management and Evaluation University of Toronto Adjunct Scientist, ICES  MedicalResearch.com:  What is the background for this study?  What are the main findings?   Response: Because atopic dermatitis is a chronic condition that is common in children, parents and physicians often wonder if it will affect overall child well-being, including their growth parameters. Previous studies were mostly cross-sectional, so we conducted a longitudinal study to follow children over time. We found that although young children with atopic dermatitis were somewhat shorter with higher BMI than children without atopic dermatitis, these differences were small and attenuated as children grew older.

Author Interviews, JAMA, Mental Health Research, USPSTF, Weight Research / 23.03.2022

MedicalResearch.com Interview with: Lori Pbert, Ph.D Professor, Department of Population and Quantitative Health Sciences Associate chief of the Division of Preventive and Behavioral Medicine Founder and Director of the Center for Tobacco Treatment Research and Training University of Massachusetts Medical School Dr. Pbert joined the U.S. Preventive Services Task Force in January 2019 MedicalResearch.com:  What is the background for this study?  Response: This is the first time that the Task Force has looked at the evidence around screening for eating disorders. It was important to address this topic because of the serious harm that these conditions can cause to people’s physical and mental health, and the tremendous toll eating disorders have on individuals and families. MedicalResearch.com:  What are the main findings? Response: After reviewing the limited available research, we determined there is not enough evidence to recommend for or against screening teens and adults for eating disorders in adolescents and adults who do not have signs or symptoms of an eating disorder or concerns about their eating. It’s important to note that this recommendation is not for people who are showing signs or symptoms of eating disorders, like rapid weight loss or gain, slow heart rate, delayed puberty, or a disruption of menstruation, or for those expressing concern about their eating.

medications-pharmaceuticals-drugsMedicine is now more widely available than ever before, and shelves are filling up with different drugs that have all sorts of impacts on the human body. Recent events such as the covid pandemic have shown how quickly new medicines can be developed and distributed throughout the world. The manufacturing process has been refined in a big way, and swift changes continue to be made on this front. However, if you were wanting to find out a bit more about how medicine is made, there is a lot to say on this particular front. Everything starts off in the initial development phase before a drug goes through its research and development, passes a number of checks and balances, and is eventually released into the wider world as a whole. So, let’s go into a little bit more detail about how medicine is actually made. (more…)

MedicalResearch.com Interview with: Ying-Hui Fu, PhD Professor, Neurology Weill Institute for Neurosciences UCSF MedicalResearch.com:  What is the background for this study?  Response: Most people are aware that a lack of sleep is associated with all sorts of health issues. However, familial natural short sleeper (FNSS) individuals sleep 4-6.5 hours a night most of their live and stay healthy. We set out to determine whether natural short sleep mutations can offer protection from various diseases. We chose Alzheimer as an example to start. (more…)
AHA Journals, Author Interviews, Blood Pressure - Hypertension / 18.03.2022

MedicalResearch.com Interview with: Paolo Palatini, M.D. Professor of Internal Medicine University of Padova Padova, Italy  MedicalResearch.com:  What is the background for this study?  Response: Up to now doctors measured blood pressure (BP) on standing only in elderly people on pharmacological treatment with the purpose of detecting orthostatic hypotension. In young-to-middle-age people BP is currently measured only in the lying or the sitting posture. Our starting point was that young borderline hypertensive people have an increased sympathetic activity and thus they might be hyperreactive to physical stimuli such as assuming the orthostatic posture which may be deleterious in the long run. This hypothesis was tested in the HARVEST, a study initiated in Italy in 1990, in which over 1200 young patients screened for stage 1 hypertension were enrolled. (more…)
Alzheimer's - Dementia, Author Interviews, Brigham & Women's - Harvard, Sleep Disorders / 18.03.2022

MedicalResearch.com Interview with: Peng Li, Ph.D. Assistant Professor of Medicine, Harvard Medical School Research Director, Medical Biodynamics Program (MBP) Division of Sleep and Circadian Disorders Associate Physiologist, Brigham and Women's Hospital MedicalResearch.com:  What is the background for this study?  Response: People commonly see increased sleep during daytime in older adults. In people with Alzheimer’s disease or dementia, daytime drowsiness or sleepiness are even more common. Prior studies have showed protective effects of short naps on cognitive performance and alertness acutely, while also there are studies that have demonstrated more daytime naps are associated with faster cognitive decline in the long-term. We sought to investigate whether daytime napping behavior predicts future development of Alzheimer’s dementia. And we noted that there had been no studies to date that have documented the longitudinal profile of daytime napping during late life objectively. (more…)
Author Interviews, COVID -19 Coronavirus, Diabetes / 17.03.2022

MedicalResearch.com Interview with: Prof. Wolfgang Rathmann MSPH Prof. of Epidemiology Deputy Director, Institute for Biometrics and Epidemiology, German Diabetes Center, Heinrich Heine University Düsseldorf, Germany MedicalResearch.com:  What is the background for this study?  Response: Diabetes is associated with a poor prognosis of COVID-19. There have been raised concerns about a bidirectional relationship between diabetes and COVID-19. Recent studies raised the possibility that SARS-CoV-2 can cause diabetes. However, there is a lack of studies investigating the incidence of diabetes after recovery from COVID-19 in mild cases. To provide more evidence, we analyzed electronic health records from 1,171 general and internal medicine practices across Germany between March 2020 and January 2021. This included 35,865 patients who were diagnosed with COVID-19. The incidence of diabetes after COVID-19 was compared with patients, who were diagnosed with an acute upper respiratory tract infection (AURI), matched for sex, age, and comorbidities including obesity, high blood pressure, high cholesterol, heart attack, and stroke.  (more…)

MedicalResearch.com Interview with: Irene A. Stafford, M.S., M.D. Associate Professor Associate Program Director Maternal - Fetal Medicine Fellowship Department of Obstetrics and Gynecology Division of Maternal Fetal Medicine McGovern Medical School at UTHealth Houston MedicalResearch.com:  What is the background for this study? Response: We have observed disproportionately high-rates syphilis in the US over the last several years, and here in Texas. As this is now leading to health alerts in our cities, it is key we bring attention to this infection regarding risks to the pregnant patient and her fetus. Syphilis carries a nearly 40% neonatal mortality rate, so testing and treating is key in preventing this devastating neonatal infection. We need to encourage and offer testing at intake to pregnancy care, and any time a patient desires to be tested for STI.   (more…)

MedicalResearch.com Interview with: Izzuddin M Aris, PhD Assistant Professor Department of Population Medicine, Harvard Medical School Division of Chronic Disease Research Across the Lifecourse Harvard Pilgrim Health Care Institute Boston, MA MedicalResearch.com:  What is the background for this study?  Response: Puberty is a key stage during child development. Previous research indicates that children in the United States are entering puberty at younger ages. These children may be in danger of developing certain diseases, such as type 2 diabetes, later in life. A better understanding of how early life factors affect puberty development is important for combating earlier puberty onset. . (more…)

MedicalResearch.com Interview with: Dr. Saundra Singh M.D., Ph.D. Founder & CEO/President Singh Biotechnology https://www.singhbiotechnology.com/       MedicalResearch.com: What is the mission of Singh Biotechnology?  
  • Our mission is to develop medicine and therapeutics that dramatically improve and save the lives of people worldwide suffering from diseases, including cancer.
MedicalResearch.com: What are the advantages of the Single Domain Antibody technology?
  • The average human antibody is 150 Kd in size and works on the outside of the cell. The advantage of the single domain nanobody is that it is significantly smaller, in fact, it is one-tenth the size (approximately 15 Kd) of the human antibody. A smaller nanobody is more useful therapeutically because, unlike many cancer drugs currently on the market, it can penetrate the blood-brain barrier, the blood-retina barrier, and the cell membrane. Moreover, our SBT-100 drug has been shown to be non-toxic in animal models.

MedicalResearch.com Interview with: Bianca V. Sanchez Department of Medical Education Geisinger Commonwealth School of Medicine Scranton, Pennsylvania MedicalResearch.com: What is the background for the study? Response: Hispanic populations have been disproportionately affected by the COVID-19 pandemic, as evident by their increased rate of infection with the virus, hospitalizations, and mortality. Previous literature has indicated that many of these individuals demonstrate increased rates of vaccine hesitancy, subsequently increasing their risk for infection. This study aimed to characterize the reasoning behind vaccine hesitancy in Hispanic populations in the hopes of addressing their concerns through targeted educational interventions. (more…)
