MedicalResearch.com Interview with: [caption id="attachment_56486" align="alignleft" width="133"]DAVID K. TUROK, MD, MPH, FACOG Clinical Senior Lecturer Honorary Consultant in Cardiology Institute of Health Informatics Faculty of Pop Health Sciences University College London Dr. Turok[/caption] DAVID K. TUROK, MD, MPH, FACOG ASSOCIATE PROFESSOR OF OBSTETRICS AND GYNECOLOGY CHIEF OF THE DIVISION OF FAMILY PLANNING UNIVERSITY OF UTAH MedicalResearch.com: What is the background for this study? Response: Researchers and clinicians have long known that copper intrauterine devices (IUDs) work extremely well for emergency contraception, using contraception after sex to prevent pregnancy. However, the hormonal IUD (levonorgestrel 52 mg IUD) has distinct characteristics that many people prefer. Namely, it reliably reduces or eliminates menstrual bleeding and cramping. Until now we did not know if the levonorgestrel IUD worked for emergency contraception. Now we know. In a first-of-its-kind study, our team at the University of Utah Health and Planned Parenthood Association of Utah found that hormonal IUDs were comparable to copper IUDs for use as emergency contraceptives.

MedicalResearch.com Interview with: [caption id="attachment_56279" align="alignleft" width="172"]Dr-Chris Clark.jpg Dr. Clark[/caption] Chris Clark, PhD Clinical Senior Lecturer in General Practice Primary Care Research Group St Luke's Campus, Exeter MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Various individual studies have suggested that a blood pressure difference between arms is associated with increased mortality and cardiovascular events since we first reported this association in 2002. Such studies have been limited, due to smaller numbers of participants, in the conclusions that could be drawn. Therefore we sought to pool data from as many cohorts as possible to study this association in more detail.  MedicalResearch.com: What are the main findings? Should it be standard practice to measure blood pressure in both arms? Response: Systolic inter-arm difference was associated with increased all-cause and cardiovascular mortality. We found that all-cause mortality increased with inter-arm difference magnitude from a ≥5 mmHg threshold. Systolic inter-arm difference was also associated with cardiovascular events in people without pre-existing disease. This remained significant after adjustment for various internationally used cardiovascular risk scores, namely ASCVD, Framingham or QRISK2. Essentially we found that each increase of 1mmHg in inter-arm difference equated to a 1% increase for a given cardiovascular risk score. When undertaking a cardiovascular assessment, or determining which arm should be used for blood pressure measurement, it is recommended to measure both arms.

Professor and director of the School of Nursing College of Health and Human Services at George Mason University USPSTF Task Force Member Dr. Kubik[/caption] Martha Kubik, Ph.D., R.N. Professor and director of the School of Nursing College of Health and Human Services at George Mason University USPSTF Task Force Member MedicalResearch.com: What is the background for this study? What are the main findings? Has the recommendation changed over the last decade? Response: High blood pressure is becoming more common among children and teens in the United States and can have serious negative health effects in childhood and adulthood, such as kidney and heart disease. However, there is not enough research to know whether treating high blood pressure in young people improves cardiovascular health in adulthood. The Task Force continued to find that there is not enough evidence to recommend for or against screening for high blood pressure in children and teens who do not have signs or symptoms.

MedicalResearch.com Interview with: [caption id="attachment_55410" align="alignleft" width="340"]Aisha T. Langford, PhD, MPH Assistant Professor  Department of Population Health Co-Director, CTSI Recruitment and Retention Core  NYU Grossman School of Medicine NYU Langone Health New York, NY 10016 Dr. Langford[/caption] Aisha T. Langford, PhD, MPH Assistant Professor Department of Population Health Co-Director, CTSI Recruitment and Retention Core NYU Grossman School of Medicine NYU Langone Health New York, NY 10016 MedicalResearch.com: What is the background for this study? Response: In 2018, the American Heart Association (AHA) published an updated Scientific Statement on Resistant Hypertension. The term apparent treatment-resistant hypertension (aTRH) is used when pseudoresistance (e.g., white coat effect, medication nonadherence) cannot be excluded. The current study was designed to investigate if Black adults with aTRH, a group disproportionately affected by cardiovascular disease, receive evidence-based approaches to lower blood pressure as recommended in the 2018 AHA Scientific Statement. Specifically, we studied healthy lifestyle factors including not smoking, not consuming alcohol, ≥75 minutes of vigorous-intensity or ≥150 minutes of moderate or vigorous physical activity per week, and body mass index <25 kg/m2; and recommended antihypertensive medication classes among US Black adults.
Alzheimer's - Dementia, Author Interviews, Blood Pressure - Hypertension, Neurology, UCSF / 10.08.2020

MedicalResearch.com Interview with: Laure Rouch, PharmD PhD Department of Psychiatry Dr. Kristine Yaffe, MD (Senior Author) Departments of Psychiatry, Neurology, and Epidemiology University of California San Francisco, San Francisco VA Medical Center, San Francisco, CA, USA MedicalResearch.com: What is the background for this study? Response: Worldwide, around 50 million people have dementia and this number is set to triple by 2050. Prevention of dementia and identification of potentially modifiable risk factors are, therefore, critically important. Postural changes in blood pressure increase with advancing age and affect 20% to 30% of older adults. Yet it has not been explored deeply how orthostatic hypotension and blood pressure postural changes variability over time are associated with dementia risk. As multiple pharmacologic and nonpharmacologic interventions may improve orthostatic symptoms, this question has major public health implications.
Author Interviews, Blood Pressure - Hypertension, Social Issues / 01.08.2020

MedicalResearch.com Interview with: Dr. Shingo Yanagiya Hokkaido University Graduate School of Medicine Sapporo, Japan MedicalResearch.com: What is the background for this study? Response: Thank you very much for your question. Hypertension is a major risk factor for cardiovascular diseases including stroke and ischemic heart disease. Due to the relatively high prevalence of hypertension, there is an increased public burden resulting mainly from cardiovascular disease. It is well known that hypertension is associated with several lifestyle factors, including excessive intake of salt or alcohol, obesity, inactivity, and other personal attributes. Since socioeconomic status affects individual lifestyles and other factors, differences in socioeconomic status may influence the risk of hypertension. Therefore, it is important to clarify whether the risk of hypertension varies among socioeconomic classes when considering an effective strategy for preventing hypertension. Based on my research of previous reports about the relationship between household income and incident hypertension, evidence is scarce for Japan. So, we investigated this in an employed population in Japan.
Author Interviews, Blood Pressure - Hypertension, UT Southwestern / 15.04.2020

MedicalResearch.com Interview with: [caption id="attachment_53914" align="alignleft" width="70"]MedicalResearch.com Interview with: DaiWai Olson, PhD, RN Professor of Neurology and Neurotheraputics UT Southwestern Medical Center Dr. Olson[/caption] DaiWai Olson, PhD, RN Professor of Neurology and Neurotheraputics UT Southwestern Medical Center MedicalResearch.com: What is the background for this study? Response: This study resonates across nursing. Kat Siaron is a Neuroscience nurse who had questions about the ‘best’ location for checking blood pressure. Like so many studies this started with a clinical question: “does it make a difference where you check the blood pressure?” She applied for a nursing research fellowship and was one of 6 nurses selected. She spent about 3 months reading articles on blood pressure and looking to see if there are any similar studies. After confirming that this has not been done, she submitted her study for approval from the Institutional Review Board and started data collection.
Author Interviews, Blood Pressure - Hypertension, Heart Disease, Weight Research / 08.04.2020

MedicalResearch.com Interview with: Zhen Yang MD PhD Department of Endocrinology, Xinhua Hospital Shanghai Jiao Tong University School of Medicine Shanghai, China   MedicalResearch.com: What is the background for this study? Response: Hypertension is a major public health problem affecting more than 1 billion people worldwide. And it is the leading cause of mortality and disability globally. Startlingly, more than half of people with elevated blood pressure were unaware of their hypertensive status in numerous surveys, partly owing to hypertension rarely shows symptoms in the early stages. Hence, hypertension is a silent killer.

How does the RAAS system interface with the COVID-19 virus? Response: Angiotensin-converting enzyme (ACE)2 is a functional receptor for coronaviruses, including Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The exponential growth of contagion by the SARS-CoV-2 all around the world has contributed to raising speculations and concerns about whether two commonly used anti-hypertensive drugs, i.e., ACE inhibitors and angiotensin receptor blockers (ARBs), have positive or negative effects in coronavirus disease 2019 (abbreviated “COVID-19”) patients with arterial hypertension on-going treatment with some of the former drugs. In effect, many professional health organizations have published statements claiming that there is not enough evidence to change the use of ACE-inhibitors or ARBs for the management of raised blood pressure (BP) in the context of avoiding or treating COVID-19 infection.
Author Interviews, Blood Pressure - Hypertension, Columbia, Heart Disease, JAMA / 17.02.2020

MedicalResearch.com Interview with: [caption id="attachment_53185" align="alignleft" width="143"]George Hripcsak, MD, MS Vivian Beaumont Allen Professor of Biomedical Informatics  Chair, Department of Biomedical Informatics Columbia University Director, Medical Informatics Services NewYork-Presbyterian Hospital/Columbia Dr. Hripcsak[/caption] George Hripcsak, MD, MS Vivian Beaumont Allen Professor of Biomedical Informatics Chair, Department of Biomedical Informatics Columbia University Director, Medical Informatics Services NewYork-Presbyterian Hospital/Columbia MedicalResearch.com: What is the background for this study? Response: Diuretics are considered among the best drugs to treat hypertension, but there are no randomized studies to tell us which diuretic is best. Hydrochlorothiazide is the most frequently used diuretic for hypertension, but another drug, chlorthalidone, is gaining favor, with the most recent US hypertension guideline expressing a preference for it. Chlorthalidone is known to be longer acting and therefore perhaps more effective. Other (non-randomized) studies have been inconsistent, and some of them imply that chlorthalidone may be more effective. But other studies have shown that chlorthalidone may have more side effects.

Juraschek, MD, PhD Assistant Professor, Harvard Medical School Beth Israel Deaconess Medical Center Division of General Medicine, Section for Research Boston, MA  02215 MedicalResearch.com: What is the background for this study? Response: Gout is a common complication of blood pressure treatment. Furthermore, 75% of adults with gout have hypertension. There are several classes of medications uses to treat hypertension. While prior studies have reported that calcium channel blockers like amlodipine lower uric acid, its effects on gout risk compared to other common first-line antihypertensive agents are unknown.

MedicalResearch.com Interview with: [caption id="attachment_50729" align="alignleft" width="200"]Yuichiro Yano MD Assistant Professor in Family Medicine and Community Health Duke University  Dr. Yano[/caption] Yuichiro Yano MD Assistant Professor in Family Medicine and Community Health Duke University  MedicalResearch.com: What is the background for this study? Response: The blood pressure (BP) guideline in the US recommend using an “average” of multiple BP measurements over time for screening for and management of high BP in young adults. While it is well known that BP varies across visits, that “variability” (i.e., visit-to-visit blood pressure variability) is dismissed as a random fluctuation in the clinical setting. Little is known regarding the clinical relevance of visit-to-visit blood pressure variability over time in young adults.

Alper, MD, MSPH, FAAFP, FAMIA Board Certifications: Family Medicine, Clinical Informatics Founder of DynaMed Vice President of Innovations and Evidence-Based Medicine Development EBSCO Health Dr. Alper[/caption] Brian S. Alper, MD, MSPH, FAAFP, FAMIA Board Certifications: Family Medicine, Clinical Informatics Founder of DynaMed Vice President of Innovations and Evidence-Based Medicine Development EBSCO Health  MedicalResearch.com: What is the background for this study? Response: We often use clinical practice guidelines as a “source of truth” for decision support for healthcare professionals and even as a standard of care for medical legal considerations.  However our experience evaluating guidelines for clinical reference support finds they are often inconsistent.  We picked one of the most common conditions managed in healthcare (ie hypertension, or high blood pressure) and sought out the top clinical practice guidelines that guide care around the world.   We systematically evaluated these guidelines against 70 specific recommendations to see how often the guidelines agreed or disagreed.
AHA Journals, Author Interviews, Blood Pressure - Hypertension, Heart Disease / 05.11.2019

MedicalResearch.com Interview with: Rachel E. Climie PhD INSERM U970, Paris Cardiovascular Research Center (PARCC) Integrative Epidemiology of Cardiovascular Disease Team, University de Paris, Paris, France.  MedicalResearch.com: What is the background for this study? Response: It is well known that physical activity (PA) is beneficial for cardiovascular health. However, little consideration is given as to whether different domains of PA have differing associations with health outcomes. Indeed, recent work has shown that high amounts of PA at work are associated with increased risk of early death, however the underlying mechanisms are unknown. In this study, we explored the relationship between physical activity at work, during leisure time and as structured sport with baroreflex sensitivity. We distinguished between the mechanical (dependent on the stiffness of the arterial wall) and neural (nerve impulses sent by the receptors on the walls of the artery) components of the baroreflex. Importantly, baroreflex sensitivity is crucial for short- term blood pressure control and reduced baroreflex function is related to higher risk of cardiac mortality and sudden death.

MedicalResearch.com Interview with: Dr Eva Muñoz Aguilera BDS MFDS MClinDent (Dist) MPerio RCSEd EFP Diploma in Periodontology and Implant Dentistry Senior Clinical Teaching Fellow in Periodontology UCL Eastman Dental Institute, London MedicalResearch.com: What is the background for this study? Response: High blood pressure and periodontitis are highly prevalent conditions that affect more than one third of the adult population worldwide. High blood pressure is the leading global cause of premature death and is the main preventable cause of cardiovascular disease,  while gum disease - also known as periodontitis - leads to severe inflammation of the gums and tooth loss. It impairs aesthetics and function and reduces quality of life. Most importantly, there is increasing evidence that periodontitis increases risk for future cardiovascular disease. Both diseases share common risk factors such as obesity and smoking and are major health problems that significantly impact on health costs. 
Author Interviews, Blood Pressure - Hypertension, Obstructive Sleep Apnea / 13.09.2019

MedicalResearch.com Interview with: Mireia Dalmases Cleries, MD Hospital Universitari Arnau de Vilanova and Santa Maria Group of Translational Research in Respiratory Medicine Lleida, Cataluña, Spain MedicalResearch.com: What is the background for this study? Response: Obstructive sleep apnea has been associated with poor blood pressure control and resistant hypertension. Moreover, it has been described that its treatment with continuous positive pressure (CPAP) could be an effective means of controlling blood pressure in this population. Nevertheless, studies assessing OSA prevalence, characteristics and association with blood pressure control in resistant hypertensive patients are limited and that’s the reason why we decided to perform this study.

Response: In the June 18, 2019 issue of Annals of Internal Medicine, we published a systematic review and meta-analysis evaluating the cardiovascular risks of white coat hypertension (WCH; i.e. elevated office blood pressure and normal out-of-office blood pressure). The goal of the meta-analysis was to clarify previous mixed results regarding the risks of untreated WCH and treated WCH. The meta-analysis examined 27 studies – including 64,273 patients – and demonstrated that untreated WCH is associated with an increased risk of cardiovascular events (36%), all-cause mortality (33%), and cardiovascular mortality (109%) compared to normotension. This risk was strongest in studies with a mean age ≥55 years or that included participants with cardiac risk factors, such as diabetes and chronic kidney disease. We found no increased cardiovascular risk associated with treated white coat hypertension.

What are the main findings?  Response: African Americans are disproportionally affected by hypertension-related cardiovascular disease compared with other racial/ethnic groups in the United States and have higher blood pressure levels inside and outside the clinic than whites and Asians. However, little is known, among African Americans, regarding whether higher mean blood pressure measured outside of the clinic setting on 24-hour ambulatory blood pressure monitoring is associated with an increased risk for cardiovascular disease events, independent of blood pressure measured in the clinic setting.
AHA Journals, Author Interviews, Blood Pressure - Hypertension, Technology / 07.08.2019

MedicalResearch.com Interview with: Kang Lee, PhD Dr Eric Jackman Institute of Child Study University of Toronto Toronto, Canada MedicalResearch.com: What is the background for this study? Response: We use a technology called transdermal optical imaging I and my postdoc invented to record facial blood flow using a regular video camera on the smartphone. This technology capitalizes on the fact that light travels beneath the facial skin and reflect off the hemoglobin under the skin. Our technology captures the minute reflected photons to decode facial blood changes due to our pulses and other physiological activities. Using machine learning, a neural network model learns to use the facial blood flow to predict blood pressures taken with a FDA approved scientific blood pressure measurement instrument. We then use the final model to predict the blood pressures of a new group of participants whose data had never been used in the model training.

Response: In the last century, we have witnessed a dramatic change in the spectrum of valvular heart disease and the prevalence of this condition has been rapidly increasing, due to population ageing, with poor patient outcomes and high healthcare costs associated with the only effective treatment available, which is valve repair or replacement. However, modifiable risk factors for valvular heart disease remain largely unknown, which limits prevention and treatment. We used a state-of-the-art, gene-based method called Mendelian randomization to determine the causality of the association between systolic blood pressure and risk of valvular heart diseases.

What are the main findings?  Response: Lifestyle changes represent the cornerstone of treatment of arterial hypertension. Alcohol and salt reduction may decrease blood pressure levels by 2 to 8 mmHg. In our study 60 minutes of midday sleep decrease 24 hours systolic blood pressure levels by up to 3 mmHg in well controlled hypertensives. That is an effect as potent as other well-established life style changes. The magnitude of blood pressure decrease might seem small, but a drop in blood pressure as small as 2 mmHg can reduce the risk of cardiovascular events by up to 10 percent.

MedicalResearch.com Interview with: [caption id="attachment_47606" align="alignleft" width="200"]Michael J. Wheeler Baker Heart and Diabetes Institute Melbourne, Victoria, Australia Michael J. Wheeler[/caption] Michael J. Wheeler Baker Heart and Diabetes Institute Melbourne, Victoria, Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: We conducted this study because separate lines of inquiry have determined that a bout of exercise can acutely lower blood pressure, and more recently that prolonged sitting can increase blood pressure over the space of a day. We wanted to know whether the blood pressure lowering effects of an exercise bout would be diminished by a subsequent period of prolonged sitting or enhanced by a subsequent period of sitting that is regularly interrupted with short walking breaks. We found an additive blood pressure lowering effect when exercise was combined with breaks in sitting as opposed to exercise plus prolonged sitting. However, this was only true for women. Men had equal blood pressure lowering effects following exercise regardless of whether-or-not subsequent sitting was interrupted

What are the main findings? Response: Lightheadedness with standing is an important risk factor for falls. Sodium is often considered a treatment for lightheadedness with standing. We examined this in the setting of a monitored feeding study where adults ate each of 3 different sodium levels for 4 weeks at a time. Participants took 5 day breaks between sodium levels and ate the sodium levels in random order. We tested the hypothesis that lowering sodium would worsen how much lightheadedness the study participants reported.

Williamson, MD Geriatric Medicine - Sticht Center Wake Forest Baptist Medical Center MedicalResearch.com: What is the background for this study? Response: A growing amount of epidemiologic research has suggested that higher blood pressure is associated with higher risk for dementia, including Alzheimer’s dementia. MedicalResearch.com: What are the main findings? Response: More than 9,300 ambulatory, community dwelling persons over age 50, 30% of whom were over the age of 75, were randomly assigned to a blood pressure goal of 120 vs 140.  Persons in the 120 group had a 19% lower risk for developing MCI an transitional stage between normal and dementia (P<.008).  There was a 17% lower risk for developing dementia but this only achieved a p value = 0.10.  The combined risk for both MCI and dementia was 15% lower in the 120 group (p<0.04).  The dementia outcome was the primary outcome but all the outcomes were pre-specified in the protocol at the beginning of the trial.  Unfortunately the blood pressure intervention was stopped after only 3.3 years due to CVD and mortality benefit and this may well have influenced the ability to reach the expected number of dementia cases.

Johnson PhD Department of Epidemiology Emory University Atlanta, GA Dr. Johnson[/caption] Dayna A. Johnson PhD Department of Epidemiology Emory University Atlanta, GA MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are several studies that have determined that African Americans have the highest prevalence of hypertension and are the most likely to have uncontrolled hypertension compared to other racial/ethnic groups. We were interested in studying whether sleep apnea contributed to hypertension control among African Americans. We found that participants with sleep apnea were more likely to have resistant hypertension than those without sleep apnea. In particular, individuals with severe sleep apnea had the highest risk of resistant hypertension. Most of the participants with measured sleep apnea were undiagnosed (96%).
