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: Raveena Chara Loma Linda University Loma Linda, CA MedicalResearch.com: What is the background for this study? latin food fried food obesityResponse: In a country struggling with an epidemic of obesity, Hispanics are one of the fastest growing population groups in the U.S. and have the highest prevalence of obesity. They are also least likely to enroll in weight reduction programs, complete them, and successfully lose weight (though reasons for this remain elusive). Obesity- a leading predisposing factor for many chronic diseases - is a complex biophysical phenomenon shaped by many factors, including a person’s social environment, health and culture. Culture permeates many aspects of one’s life including how a person views weight and behaviors associated with eating and physical activity. Indeed, for many values and norms about what is culturally acceptable and views on “body weight” vary culturally and affect their decisions about weight and weight loss. This too is the case within the Hispanic population in the US. Given the rising human and financial impact of obesity, preventing and reducing obesity, diabetes and other weight related medical conditions is a growing priority, especially for low income Hispanics. 
Aging, Geriatrics / 26.01.2021

elderly-aging-older-parentsOne of the most difficult conversations that you will need to have with your aging parents throughout their retirement is about the future. Though no matter how difficult this conversation may be, it is vital that you can plan for what might happen as a family to ensure that you are prepared for anything that comes your way. If you are struggling to do this, here are some top tips to help you comprehensively plan for your parent’s future, so they can have the most comfortable lives possible, and you do not have to worry for them. Here are some to do lists to help you get started:.

1.    Look at Assisted Living Facilities

Although you might believe that your parents will always be healthy enough to live at home, this is not always the case. There are many common health conditions such as dementia, which may leave your parents needing round-the-clock care, as well as general ill health and frailty as they start to show the signs of aging. To make sure that you know that your parents are well-looked after when the time comes, you should consider researching assisted living facilities now. This will allow you to relax in knowing that both you and your loved one are happy with the home you have chosen for them. For instance, if you are looking for assisted living Fort Lauderdale, Belmont Village can offer your parents a range of care options, and you can rest in the knowledge that they are being cared for.

2.    Sort Their Finances

Many adult children leave their parents to handle their finances for fear of taking over or looking greedy when it comes to their eventual passing. However, helping your parents sort their finances out now can ensure that they will be able to pay for all of the medical care they may need and ensure that they have enough money to live on until the end of their lives. Sorting these finances out early, such as looking at the pension schemes and organizing the assets they have to their name, will ensure that they do not come unstuck later and enable them to set a budget around their financial situation.

3.    Create a Will

Although it is easy to dismiss probate as something that you do not want to think about or discuss with your parents, helping them create a will and knowing what is inside of it is important if they pass away suddenly and unexpectedly, then you can help them to make a will by contacting a solicitor or encouraging them to complete a DIY will-making kit. You should always make sure that DIY wills are legally valid, though. Knowing what is inside of the will can be important so that you can make sure that their wishes are carried out on their death and that no forgery or other issues occur.
Author Interviews, Biomarkers, COVID -19 Coronavirus / 25.01.2021

MedicalResearch.com Interview with: [caption id="attachment_56468" align="alignleft" width="167"]Marlene Cano MD. PhD. Post-Doctoral Research Fellow in Pulmonary Transplant Immunology Division of Pulmonary and Critical Care Department of Medicine Washington University/Barnes-Jewish Hospital Saint Louis, MO Dr. Cano[/caption] Marlene Cano MD. PhD. Post-Doctoral Research Fellow in Pulmonary Transplant Immunology Division of Pulmonary and Critical Care Department of Medicine Washington University/Barnes-Jewish Hospital Saint Louis, MO MedicalResearch.com: What is the background for this study? How does this test differ from other tests for COVID-19?   Response: We know COVID-19 causes a wide spectrum of disease, and that while many develop only mild uncomplicated illness, others develop severe respiratory failure, multi-organ failure and death. These patients often require prolonged hospitalization, ICU level care and even mechanical intubation for respiratory support. However, we still do not have a great way to identify which patients are likely to develop severe disease. We felt it was important to have a test that could act as sort of a ‘biomarker’ that we could measure early in COVID-19 patients and would help predict which patients would develop severe disease. From prior work, we knew that mitochondrial DNA, which are proinflammatory molecules that are released into the circulation from damaged organs could be this such ‘biomarker’. So, we measured the levels of mitochondrial DNA circulating in the plasma of patients with COVID-19 at the time they first presented to the hospital. Then we investigated if higher levels of mitochondrial DNA indeed predict the development of more severe disease. Currently there are no ‘biomarker’ tests specific for COVID-19. We do currently measure levels of other markers in the hospital that we feel might help us assess overall how sick patients may be, but these are very non-specific and assess only level of inflammation. This test instead can measure level of tissue injury.

Response: Alzheimer's disease is one of the greatest public health challenges. From the moment the first lesions appear in the brain to the clinical manifestations, up to 20 years can pass. Today we can detect the presence of these initial lesions through biochemical markers such as amyloid-β, which is one of the main proteins accumulated in the brains of Alzheimer's patients. The prevalence of cerebral amyloid-β pathology in cognitively asymptomatic individuals increases with age. It has been estimated that 21.1% of the population at the age of 65 will have a positive amyloid scan or a pathological cerebrospinal fluid (CSF) amyloid-β determination, and which will double by the age of 90. Due to the aging of our societies and advances made in medical care, an increasing number of elderly and more fragile people are considered candidates for major surgery. In preoperative screenings, respiratory and cardiovascular functions are routinely checked; however, it is not commonly assessed how the brain is going to cope with the intervention. In the clinic, the patient’s relatives frequently tell us that the memory problems began after a surgical procedure or a hospital admission. This posed us the following question: is this just a recall bias or has surgery triggered the appearance of the symptoms in a previously affected brain?”

MedicalResearch.com Interview with: [caption id="attachment_56455" align="alignleft" width="200"]Dr-Sara Machado.jpeg Dr. Machado[/caption] Sara Machado PhD Fellow at the Department of Health Policy London School of Economics and Political Science MedicalResearch.com: What is the background for this study? Response: Physician distribution is a determinant of health care access, so knowing how physician density patterns evolve over time is important if we are trying to address disparities in access to care. Moreover, the last 10 years have brought about changes in health care coverage, across the US. Recent evidence points to an uneven physician distribution between urban and rural communities. We examined recent trends in physician density by physician category across rural and urban US counties.  MedicalResearch.com: What are the main findings? Response: We have two main findings.
  • First, density of primary care physicians steadily decreased in more than half of rural counties (994 out of 1,976).
  • Second, medical specialist density, which would care for cardiovascular and pulmonary disease, for example, has been largely stagnant in rural counties, at the lowest density levels (less than 10 physicians per 100,000), and increasing in metropolitan counties.

MedicalResearch.com Interview with: [caption id="attachment_56433" align="alignleft" width="150"]Kent Hoskins, MD Eileen Lindsay Heidrick Professor in Oncology Division of Hematology/Oncology University of Illinois at Chicago Director of Cancer Genetics Co-Leader, Breast Cancer Research Group University of Illinois Cancer Center Dr. Hoskins[/caption] Kent Hoskins, MD Eileen Lindsay Heidrick Professor in Oncology Division of Hematology/Oncology University of Illinois at Chicago Director of Cancer Genetics Co-Leader, Breast Cancer Research Group University of Illinois Cancer Center MedicalResearch.com: What is the background for this study? Response: The racial disparity in breast cancer mortality emerged in the US in the late 1980s in the wake of widespread implementation of mammography screening and the development of successful systemic adjuvant therapies for early breast cancer. Unfortunately, more than three decades later, Black women in the US still have a 40% higher mortality rate from breast cancer compared with non-Hispanic White women despite similar disease incidence. Health disparities research has primarily focused on the fact that Black women have a higher incidence of the aggressive triple-negative subtype, and that they are more likely to present with more advanced stages of disease. As important as those factors are, in recent years our group and others reported that Black women with hormone receptor-positive breast cancer have worse survival than non-Hispanic white women even after adjustment for stage at diagnosis and treatment. Since nearly 2/3 of breast cancers in Black women are hormone receptor-positive, this is a significant contributor to the overall mortality disparity. Importantly, these studies also suggested that Black women disproportionately develop biologically aggressive forms of hormone-dependent breast cancer, which is typically considered a more favorable disease subtype. Using data on more than 70,000 patients from the SEER registry that is linked to data from Genomic Health Laboratory, which provides the Oncotype DX recurrence score (the most commonly ordered prognostic/predictive multi-gene expression assay for early breast cancer), we set out to address three questions: 1) is there evidence of disproportionately aggressive tumor biology among Black women with hormone receptor (HR)-positive breast cancer, as reflected in the Oncotype DX recurrence score? 2) Is there a racial survival disparity even among patients with early stage, axillary node-negative tumors with comparable recurrence scores on the Oncotype assay? and 3) Is there is a difference in the prognostic accuracy of the Oncotype assay between Black and non-Hispanic white patients, since there was limited representation of Black women in the development and validation of the Oncotype assay and other prognostic/predictive assays?

Our work provides accurate estimates of who has  (SLE) among the major racial/ethnic groups in the United States and that our estimates for SLE approach the FDA’s definition or a rare disease.

MedicalResearch.com interview with: Dr. Stephen Brand, Chief Development Officer Mycovia Pharmaceuticals [caption id="attachment_56443" align="alignleft" width="189"]Dr.Stephen-Brand.jpg Dr. Brand[/caption]  Dr. Stephen Brand discusses the results of Mycovia’s three Phase 3 studies for recurrent vaginal yeast infections (RVVC )and what’s next for the company.  MedicalResearch.com: What is the background for these Phase 3 studies? Answer: Our Phase 3 clinical program for our oral therapy oteseconazole was comprised of three trials enrolling more than 870 patients at 176 sites across 11 different countries. Two of these trials, referred to as VIOLET were identical Phase 3 randomized, double-blind, placebo-controlled clinical trials to evaluate the safety of oteseconazole and its ability to prevent episodes of recurrent vulvovaginal candidiasis (RVVC), commonly referred to as chronic yeast infection. The trials took place over 48 weeks in subjects with an established disease history of at least three episodes of acute VVC in the past 12 months. More than 650 patients randomized at 125 sites across 11 countries. The VIOLET trials consisted of two parts: During the first part of the study which lasted two weeks after patients presented with an active VVC episode, patients were treated with three sequential 150mg doses of fluconazole. The second part consisted of 12 weeks, when the patient either took oteseconazole 150mg or a placebo once weekly (according to a random assignment), and then a 36-week follow-up period. In addition, subjects participating in the VIOLET trials in the U.S. who remained infection-free at their Week 48 visit were offered the opportunity to participate in an extension study and are being monitored for an additional 48 weeks to further define the long-term protection profile of oteseconazole. Eighty-five subjects are enrolled. The third Phase 3 study, called ultraVIOLET, was designed to complement and extend VIOLET as a 50-week randomized, double-blind, placebo-controlled clinical trial to evaluate the safety and efficacy of oteseconazole. In addition the study compared the effectiveness of oteseconazole compared to fluconazole, the current standard of care, to treat an acute VVC infection in the RVVC population. A total of 220 patients were randomized at 51 sites in the U.S. for the ultraVIOLET trial. The ultraVIOLET trial consisted of two parts: In the first part of the study RVVC subjects presenting with an active infection were randomized to receive either 2 days of dosing with oteseconazole or 3 sequential 150 mg doses of fluconazole (every 72 hours). The second part consisted of 11 weeks, when the patient took either oteseconazole or a placebo weekly (according to the random assignment from the first part of the study), and then a 37-week follow-up period.

Response: In the course of our clinical work, we have noticed a predominance of musculoskeletal complaints among some of COVID-19 patients who are otherwise clinically well, and a small subset of them who develop a viral arthralgia (joint pains) sometimes occurring separately from the onset of acute respiratory symptoms. Besides a few isolated case reports, there was not much described about COVID-19 associated viral arthralgia in the literature. Clinicians are well aware of the need to test for COVID-19 when patients present with cough or shortness of breath. However, when they present as joint pains without any respiratory symptoms, a diagnosis of COVID-19 could easily be missed. Due to overlapping clinical features like low platelet count and elevated liver enzymes, they could easily be misdiagnosed as having other vector-borne infections such as dengue fever, if clinicians do not have a high clinical suspicion of COVID-19. Hence we decided to describe the epidemiology and various presentations of musculoskeletal manifestations of COVID-19 in our cohort of patients.

Response: Diabetes has been recognized as one of the major comorbidities associated with higher mortality in the context of the spreading COVID-19 pandemic, but ways to improve outcome in this at-risk population are lacking. Metformin is the most common medication used for type 2 diabetes. In addition, it is sometimes prescribed to people with prediabetes or to women with polycystic ovary syndrome (PCOS).

Milliken Department of Internal Medicine Washington University in St. Louis Dr. Kim[/caption] Brian Kim, MD Associate Professor of Dermatology Co-Director, Center for the Study of Itch & Sensory Disorders John T. Milliken Department of Internal Medicine Washington University in St. Louis MedicalResearch.com: What is the background for this study? Response: Patients with eczema suffer from chronic itch due to the rashes they have on their body. However, as a physician, I have always noticed that patients with eczema will have sudden flares of their itching all over there body that is often triggered by what appear to be allergens – being around a cat, pollen, mold in a house, etc. Eczema is in the family of allergic diseases such as food allergy, asthma, and hay fever. All of these conditions are noted for patients being reactive to allergens by way of an antibody called IgE that coats a cell called the mast cell. Upon IgE binding an allergen, mast cells produce tons of histamine which can cause symptoms like itching. So we speculated that perhaps because patients with eczema have such misbehaving IgE, that exposure to allergen is what triggers this kind of severe itch flare that we see in patients.

Response: Patients with COVID-19 frequently need to come to the intensive care unit (ICU), where we use mechanical ventilation to support their lungs as they get over the intense inflammation caused by the virus.  During the first wave of the virus we noted that a lot of our patients appeared to be developing secondary infections (infections they didn’t have when they came into the ICU). We therefore rolled out a rapid diagnostic test for these secondary bacterial infections that we had developed previously, and this study reports the use of this diagnostic and also describes the types of bacteria seen.  To see if the increase in secondary infections was due to COVID specifically, we compared them to patients who were managed in the same ICU but who did not have COVID.

Pedersen, Ph.D. Adjunct Behavioral Scientist, RAND Associate Professor of Psychiatry and Behavioral Sciences Keck School of Medicine University of Southern California MedicalResearch.com: What is the background for this study? Response: In November of 2016, CA voted to legalize cannabis for sale and possession to adults 21 and older for recreational use. It wasn’t until January of 2018 that stores in most parts of LA County (we call these “outlets”) were legally able to begin selling recreational cannabis. We were collecting data from about 2,500 young adults in LA County as part of a longitudinal study (Principal Investigator Elizabeth D’Amico at RAND) and were able to look at cannabis use and intentions assessed at a period prior to the opening of the recreational cannabis outlets (pre-January 2018) to a period when those outlets were open (after January 2018). It has been suggested that once cannabis was more available for recreational purchase (and not just for medical purposes among those enrolled in CA’s medical marijuana program), use of cannabis among young adults would increase.

Response: Food insecurity is the inability to afford or access nutritionally adequate and safe foods for an active, healthy lifestyle. Rates of food insecurity were projected to rise during the COVID-19 pandemic; however, prior studies had not examined the association between food insufficiency, the most extreme form of food insecurity, and mental health. MedicalResearch.com: What are the main findings? Response: Using a large national sample of nearly 64,000 adults, we found that food insufficiency rose from 8.1% to 10.0% during the pandemic. People of color and younger adults had higher risk of food insufficiency. People living in poverty or experiencing recent job loss were at higher risk of food insufficiency. Food insufficiency was associated with symptoms of anxiety, worrying, and depression. Hunger, exhaustion, and worrying about not getting enough food to eat may worsen depression and anxiety symptoms. Receiving food assistance alleviated the relationship between food insufficiency and poor mental health.

MedicalResearch.com Interview with: Karan Lal, DO, Marketing Committee Member for the Society for Pediatric Dermatology, Dermatologist at UMass Memorial Medical Center. Dr. Lal discusses the recent study of a procedure to remove black dye from henna tattoos. MedicalResearch.com: What is the background for this study? Response: Para‐phenylenediamine, a dye frequently added to henna tattoos to create the black color, is a potent contact allergen. Severe contact dermatitis may arise within days even after the first application. Our objective was to develop a method for rapid and complete removal of para‐phenylenediamine‐containing black henna tattoos from the skin, an important problem many physicians are confronted with, but for which no simple method exists.

MedicalResearch.com Interview with: Prasanna Venkataraman MBBS Thomas H. Marwick MBBS, PhD Baker Heart and Diabetes Research Institute Monash University, Melbourne Melbourne, Australia   MedicalResearch.com: What is the background for this study?
  • Coronary artery calcium score (CAC) quantifies coronary calcium as determined by computed tomography and is a good surrogate marker for overall coronary plaque burden. It can help to reclassify patients at intermediate risk – many of whom are actually at low risk and can be reassured. Conversely, the finding of coronary calcium can also motivate patients (and their clinicians) to more aggressively control their cardiovascular risk factors. This is particularly problematic in those with a family history of premature coronary artery disease, where standard risk prediction tools are less accurate. However, CT CAC does not routinely attract third party payer support limiting its access and utilisation.
  • We screened 1084 participants who have a family history of premature coronary disease and a 10-year Pooled cohort Equation (PCE) cardiovascular risk >2% with CAC. We then assessed the cost-effectiveness of commencing statins in those with any coronary calcium compared to a strategy of no CAC testing and commencing statins if their PCE risk was ≥7.5% consistent with current guidelines.

Response: Bimagurmab is a monoclonal antibody that blocks the activin type 2 receptor. This receptor is found mainly on skeletal muscles and when blocked acts to stimulate muscle growth. Bimagrumab was developed as a potential treatment for skeletal muscle disorders. However, the first-in-man studies revealed an unexpected response to the drug: not only did skeletal muscle mass increase, but marked lowering in body fat and improved insulin sensitivity were observed. The current study was launched to follow up on these initial observations.

Response: Over twenty years ago we identified the existence of a non-genetic form of inheritance through analysis of environmentally induced epigenetic transgenerational inheritance of disease, now well established in a number of species including humans.  I was giving a talk on this topic at a meeting in Spain.   This study was initiated following the scientific meeting in Spain with an in vitro fertilization clinical group that said they had access to sperm from males with and without autistic children.  It took several years to collect and characterize the samples, and find financial support for the study.  Once this was done then we did the molecular analysis to see if the sperm from fathers with autistic children had epigenetic, DNA methylation alterations, that associated with them having offspring with autism.
Author Interviews, COVID -19 Coronavirus, Pulmonary Disease / 12.01.2021

MedicalResearch.com Interview with: [caption id="attachment_56399" align="alignleft" width="200"]MedicalResearch.com Interview with: Dr. Townsend Department of Infectious Diseases St. James's Hospital and Department of Clinical Medicine Trinity Translational Medicine Institute Trinity College, Dublin, Ireland MedicalResearch.com: What is the background for this study? Response: Much is known about the clinical characteristics and pathological features of acute SARS-CoV-2 infection, but there is relatively little known about post-COVID recovery. This has come under increasing scrutiny in light of reports that patients suffer persistent symptoms beyond resolution of initial infection, known as long COVID. We set out to assess patients in our post-COVID clinic for ongoing ill-health, with particular focus on fatigue and breathlessness. Given that COVID-19 primarily affects the respiratory system, we also evaluated respiratory recovery. Patients underwent chest radiography and six-minute-walk testing, as well as routine blood tests including inflammatory markers and D-dimers. We included both patients who were admitted during their acute infection as well as those managed in the community in order to capture the full spectrum of disease. MedicalResearch.com: What are the main findings? Are there any markers that suggest a higher risk of persistent post-Covid symptoms? Response: We assessed 153 patients, of whom 74 had required admission during initial infection, at a median of 75 days post-infection. We found persistent ill-health was common in those attending our clinic, with 62% reporting that they did not feel back to full health. Almost half (47%) met the case definition for fatigue, as assessed by the Chalder Fatigue Scale. Patients also reported moderate breathlessness on six-minute-walk-test, with a median modified Borg score of 3. Reassuringly, we saw persistent abnormal chest x-rays in only 4% of patients, and the median distance covered during walk test was 460m, which approaches the normal range for healthy populations. Furthermore, there were only two patients that experienced oxygen desaturation to less than 90% during walk test. We investigated the potential predictors and associations of breathless, distance covered and abnormal chest x-ray using a multivariate regression analysis model. Interestingly, we found that severity of initial infection, as defined by requirement for admission to hospital, peak CRP and peak oxygen requirement, was not associated with severity of self-reported symptoms. Thus, there were no features from initial infection identified that could predict persistence of symptoms beyond initial infection. MedicalResearch.com: What should readers take away from your report? Response: This study highlights several important points: 1. Ill-health, fatigue and breathlessness are common in the aftermath of SARS-CoV-2 infection 2. These appear unrelated to initial severity of infection. This has implications for the potential number of patients who may be affected, as well as increased burden on the healthcare system 3. We show reassuringly low rates of abnormal chest x-rays as well as reassuring objective six-minute-walk test results, suggesting that clinically significant pulmonary damage is uncommon. MedicalResearch.com: What recommendations do you have for future research as a result of this work? Response: We would suggest that future studies on the aftermath of COVID-19 include patients across the spectrum of disease severity, rather than focusing only on those who required hospitalization. The range and frequency of post-COVID symptoms are being emerging in the literature, and there is a need for mechanistic studies to understand the underlying pathology. We have no disclosures to declare. Citation: Liam Townsend, Joanne Dowds, Kate O'Brien, Grainne Sheill, Adam H Dyer, Brendan O'Kelly, John P.

This has come under increasing scrutiny in light of reports that patients suffer persistent symptoms beyond resolution of initial infection, known as long COVID. We set out to assess patients in our post-COVID clinic for ongoing ill-health, with particular focus on fatigue and breathlessness. Given that COVID-19 primarily affects the respiratory system, we also evaluated respiratory recovery. Patients underwent chest radiography and six-minute-walk testing, as well as routine blood tests including inflammatory markers and D-dimers. We included both patients who were admitted during their acute infection as well as those managed in the community in order to capture the full spectrum of disease.

Blasco, PhD Director of the Spanish National Cancer Research Centre Head of the Telomeres and Telomerase Group – CNIO  MedicalResearch.com: What is the background for this study? Response: In my group we have previously described that telomere dysfunction in alveolar type II (ATII) cells in the lung is sufficient to induce pulmonary fibrosis in mice, thus demonstrating that these cells, which have a role in lung regeneration, are at the origin of the disease (Povedano et al., Cell Reports, 2015). Indeed, we further demonstrated that telomere elongation in these cells by using a gene therapy strategy based on telomerase activation, was sufficient to stop the progression of pulmonary fibrosis induced by short telomeres in mice (Povedano, eLife, 2018).

Wadhera, MD, MPP, MPhil Division of Cardiovascular Medicine, Beth Israel Deaconess Medical Center Associate Program Director, Cardiovascular Medicine Fellowship Assistant Professor of Medicine, Harvard Medical School  MedicalResearch.com: What is the background for this study? Response: The direct toll of the novel coronavirus disease 2019 (COVID-19) in the U.S. has been substantial, but concerns have also arisen about the indirect effects of the pandemic on higher-risk patients with chronic medical conditions, such as cardiovascular disease. Hospitalizations for acute cardiovascular conditions, including myocardial infarction, heart failure, and stroke precipitously declined during the early phase of the pandemic. These patterns have raised concern that patients may be avoiding hospitals due to fear of contracting SARS-CoV-2, and that some have died from cardiovascular conditions without seeking medical care. In addition, there has been growing concern about the the effects of health-care system strain and the deferral of semi-elective procedures on patients with cardiovascular conditions.

As a result, they are exposed to indoor air far more often than outdoor air (the atmosphere). Yet, the chemistry (and air quality) of the atmosphere has been studied far more often than indoor air. Air quality is linked to direct health impacts, and the emissions indoors can be ventilated outdoors where they can undergo chemical transformations that have climate and health impacts. Beyond exposure to indoor air, humans contribute significantly to overall indoor air quality by breathing, sweating, and applying personal care or hygiene products. Previous studies have investigated these emissions at a high level of chemical detail for seated or standing individuals indoors, but limited chemical and time-resolution studies have been conducted while people are exercising indoors.

Response: This study builds on recent population based studies where opium use was found to be possible risk factor for pancreatic cancer. Although opium use is not a common recreational habit in the United States, opioid use has been rising remarkably over the past decade. In fact, opioid misuse and overdose have evolved into a public health crisis here with increasing opioid prescription use and abuse over the past decade.

Butler, MD, FAAP, MACP, FIDSA Deputy Director for Infectious Diseases Centers for Disease Control and Prevention Atlanta, GA  30333 MedicalResearch.com: What is the background for this study? Response: There are still disagreements about the significance of transmission of SARS-CoV-2 from asymptomatic persons.  It has been known since at least March 2020 that, unlike the closely related coronavirus that causes SARS, transmission of COVID-19 from asymptomatic and presymptomatic persons occurs and that at least 30% of infected persons do not develop symptoms.  Estimating the proportion of transmissions from persons without symptoms informs the decision analysis for prioritization of community mitigations opportunities:  wearing of masks, social distancing, and hand hygiene. If only a low proportion of transmission occurs from people without symptoms, these interventions would be less likely to control transmission when broadly applied in the community.  On the other hand, if a significant proportion of spread is from infected persons without symptoms, the value of these measures is enhanced. Additionally, obtaining strategic and systematic screening tests for SARS-CoV-2 to identify and isolate persons without symptoms in selected settings, such as congregational housing settings, will have greater potential impact if spread from persons without symptoms is common.

Thomas Jr. Distinguished Professor and Chair Department of Surgery Professor, Department of Biomedical Engineering The University of North Carolina at Chapel Hill Chapel Hill, NC 27599-7050 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Fluoroquinolones are a commonly prescribed antibiotic.  Recent data from Taiwan, Sweden, and Canada suggests that the use of fluoroquinolones increase the short-term risk of aneurysm formation in certain older patient  populations.  As such, the FDA issued a warning in 2018 regarding the use of fluoroquinolone antibiotics suggesting that this class of antibiotics should not be used in patients at increased risk. The FDA defined the high risk population as those with a history of aneurysms or blockages, high blood pressure, certain genetic disorders related to blood vessels, and the elderly.  However, we hypothesized that this risk of taking fluoroquinolones extends to all patient populations and not just high risk patient populations.

What conditions have fecal matter transplants been previously studied in (ie c. diff)? Response: “Many melanoma patients do not respond to immunotherapy and even among responders, many eventually progress. Extensive research has been conducted in order to overcome resistance to immunotherapy and modulation of the gut microbiota, is one of the promising leads. The gut microbiome has been shown to influence response to immunotherapy in preclinical mouse models and observational patient cohorts. Currently FMT is being used for the treatment of C. Difficile that is resistant to antibiotics, but it is also being evaluated as a treatment option for other disease states such as inflammatory bowel disease and obesity.”

Would you explain what is meant by the blood brain barrier? How will nanoparticles facilitate transport of drugs into the brain? Response: Over the past few decades, researchers have identified promising therapeutic agents that can target the biological pathways involved in brain diseases. Unfortunately, clinical translation of these therapeutics is limited by their inability to cross the blood brain barrier (BBB) and enter the brain at therapeutically effective levels. The BBB is a highly selective semipermeable border of cells that prevents molecules in the circulating blood from non-selectively crossing into the brain tissue. We have developed a simple targeted nanoparticle platform that can stably encapsulate therapeutic agents and enable their therapeutically effective delivery into the brain. In this work, we have demonstrated the utility of this platform for the treatment of traumatic brain injury (TBI), which is a leading cause of death and disability in children and young adults, with millions of people suffering TBI each year in accidents, sports, and military conflicts. Following primary injury, which is a result of the mechanical impact to the brain, secondary injury gradually occurs over months to years and can lead to neurological dysfunctions, including Alzheimer’s and Parkinson’s diseases. After TBI, the BBB is physically breached for a short time and previous approaches to achieve therapeutically effective transport of drugs across the BBB have been severely limited to utilizing this very short window. However, the extent to which the BBB is physically breached in TBI varies greatly across the patient population. Therefore, current approaches are applicable to only a subset of injuries with substantially breached BBB. Moreover, BBB can self-repair within a few hours to weeks post-injury to restore its integrity. Hence, physical breaching of BBB offers a limited window for therapeutic interventions, which is not ideal as the secondary injury can last months to years and may require repeated dosing over long term. The nanoparticle platform developed in this work can enable therapeutically effective delivery of drugs into the brain, irrespective of the state of the BBB. We achieved this by precise engineering of the surface properties of nanoparticles, which maximized their transport across the BBB. The therapeutic used in this study was a small interfering RNA (siRNA) molecule designed to inhibit the expression of the tau protein, which is believed to play a key role in neurodegeneration. Poly(lactic-co-glycolic acid), or PLGA, a biodegradable and biocompatible polymer used in several existing products approved by the U.S. Food and Drug Administration was used as the base material for nanoparticles. We systematically engineered and studied the surface properties of the nanoparticles to maximize their penetration across the intact, undamaged BBB in healthy mice. This led to the identification of a unique nanoparticle design that maximized the transport of the encapsulated siRNA across the intact BBB and also significantly improved the uptake by the brain cells.

MedicalResearch.com Interview with: Srinath Adusumalli, MD, MSc, FACC Assistant Professor of Clinical Medicine Division of Cardiovascular Medicine| Penn Medicine Lauren A. Eberly, MD, MPH Division of Cardiovascular Medicine, Department of Medicine Hospital of the University of Pennsylvania, Philadelphia MedicalResearch.com: What is the background for this study?   Response: The coronavirus disease 2019 (COVID-19) pandemic has uprooted conventional health care delivery for routine ambulatory care, requiring health systems to rapidly adopt telemedicine capabilities. At Penn Medicine, we wanted to ensure that as we developed a new system of telemedical care, we were reaching all of the patients we serve and access to care was maintained. As such, we undertook this study to examine utilization of care as we continued to iterate on and develop our telemedical system of care.
