MedicalResearch.com Interview with: [caption id="attachment_60654" align="alignleft" width="150"]Chi-yuan Hsu, MD, MSc (he/him/his)Professor and Division Chief Robert W. Schrier Distinguished Professor Division of Nephrology  University of California, San Francisco Dr. Chi-yuan Hsu[/caption]   Chi-yuan Hsu, MD, MSc (he/him/his) Professor and Division Chief Robert W. Schrier Distinguished Professor Division of Nephrology University of California, San Francisco     MedicalResearch.com: What is the background for this study? Response: Acute kidney injury (AKI) had previously been considered a reversible short-term medical problem among hospitalized patients without long-term sequalae in that there is recovery of kidney function back to baseline should the patient survive the hospitalization. Then about 15 years ago, the concept began to shift as research by us and others showed that for patients with severe AKI (e.g. AKI severe enough to require acute dialysis in the hospital), there was more rapid subsequent loss of renal function.  Now based largely on additional observational studies in humans (and animal models), many nephrologists and opinion leaders think that even mild to moderate cases of AKI have long-term sequelae.  We are concerned that the paradigm has swung too much in the opposite direction and we questioned the results of many published studies which did not fully account for differences in background kidney function among those who did and did not experience AKI.

MedicalResearch.com Interview with: [caption id="attachment_60494" align="alignleft" width="150"]Rebecca E. Graff, ScDAssistant Professor University of California, San Francisco Department of Epidemiology & Biostatistics Mission Hall: Global Health & Clinical Sciences Building San Francisco, CA 94158 Dr. Graff[/caption] Rebecca E. Graff, ScD Assistant Professor University of California, San Francisco Department of Epidemiology & Biostatistics Mission Hall: Global Health & Clinical Sciences Building San Francisco, CA 94158 MedicalResearch.com: What is the background for this study? Response: PSA screening for prostate cancer has long been controversial. While it does seem to reduce mortality attributable to prostate cancer, it also results in the diagnosis of many cancers that never otherwise would have presented symptomatically. In addition, PSA levels are affected by factors other than prostate tumors (e.g., age, prostatic inflammation, and genetics), such that men with high PSA values are often referred for biopsy but do not end up having cancer. We hypothesized that accounting for the genetic component of PSA could yield adjusted values that better distinguish who should get a prostate biopsy.

Our study used a nationwide sample of almost two million older Veterans who all had access to care through the Veterans Health Administration (VHA), and we examined 5 race or ethnicity groups: American Indians or Alaska Natives, Asians, Blacks, Hispanics, and Whites. Our results show that dementia risk is higher for Black and Hispanic Veterans compared to white Veterans, even when education and medical factors are considered.

Woodruff, MD Department of Dermatolog University of California, San Francisco Dr. Woodruff[/caption] Carina M. Woodruff, MD Department of Dermatolog University of California, San Francisco MedicalResearch.com: What is the background for this study? What are the main findings? Response: Rigorous hand hygiene has been an important component of the CDC's COVID-19 guidelines. With millions of Americans now using hand sanitizers regularly, we are seeing many more cases of hand dermatitis. Our study evaluated the key product features and most common allergens in the top-reviewed, commercial hand sanitizers sold by major US retailers. We found that the most common potential allergens were tocopherol, fragrance, propylene glycol and phenoxyethanol. Our study also showed that nearly 1 in 5 marketing claims on these products was misleading. For example, 70% of sanitizers with the marketing claim "hypoallergenic" included at least one common allergen in its formulation.

Response: I have spent the last 30 years working on perioperative risk reduction, developing medications and approaches to risk reduction. Part of this work utilized epidemiologic analysis of medication patterns of use to test if they are associated with reductions in morbidity and mortality. This work analyzed data in the VA Corporate Data Warehouse (CDW) which provides access to the VA, best in the world electronic health care record system, VISTA.  With the COVID-19 pandemic I realized that the analytic techniques we had utilized for perioperative cardiac risk reduction could be used to search for medications to reduce the risks for acute COVID-19 infection. We identified four classes of medications that reduced the risk of death in acute COVID-19 infection. We then turned our attention to medications to reduce the incidence, severity, and duration of long-term sequelae of COVID-19 infection also known as Long COVID or COVID Long Hauler Syndrome. One of the questions that people were asking was what was the effect of vaccination on Long COVID? We began that work by looking at the effect of vaccination on COVID infections and found the dramatic decrease in efficacy of vaccines with the spread of the Delta Variant. We published this work to notify the public and public health community of the decreased efficacy of the vaccines in the face of the Delta variant and reiterate the need for secondary public health prevention measures such as masks, social distancing, vaccination, and boosters.

Response: There has been a great deal of controversy recently about how race should be considered in medicine, including its use in estimating kidney function (e.g. https://jamanetwork.com/journals/jama/fullarticle/2769035).  A recent paper published in JAMA Network Open by Zelnick et al suggested that removing the race coefficient improves the accuracy of estimating kidney function (https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2775076) in the Chronic Renal Insufficiency Cohort, a NIH-funded study (www.cristudy.org). We are core investigators of the Chronic Renal Insufficiency Cohort Study and were not involved in the Zelnick’s study that was based on a public use dataset.  Because we were surprised by the methodological approach they took and the conclusion they came to, we implemented our own analysis of the data.

Response: Obstructive sleep apnea is very common, undiagnosed and undertreated. The AHA Scientific Statement was prepared to increase awareness amongst physicians and patients about this condition and to encourage more screening and therapy as appropriate. Obesity is certainly one of the significant risk factors for sleep apnea and we highlight this in the Scientific Statement: “The risk of OSA correlates with body mass index, and obesity remains the one major modifiable risk factor for OSA. In a population-based cohort study of 690 subjects, a 10% weight gain was associated with nearly 32% increase in the apnea-hypopnea index (AHI), and even modest weight control was effective in reducing the new occurrence of sleep-disordered breathing. An even stronger correlation exists between OSA and increased waist circumference and neck size. Neck sizes predisposing to OSA are usually >17 and 16 in for men and women, respectively.”

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).

Pedersen, Ph.D. Adjunct Behavioral Scientist, RAND Associate Professor of Psychiatry and Behavioral Sciences Keck School of Medicine University of Southern California Dr. Pedersen[/caption] Eric R. 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: Silvia Schirò MD Department of Radiology and Biomedical Imaging University of California, San Francisco MedicalResearch.com: What is the background for this study?  Response: Knee osteoarthritis (OA) is worldwide the second most frequent cause of lower extremity disability, and it has a global incidence of 199 cases per 100.000, including over 14 million people with symptomatic knee OA in the US. Overweight and obese individuals have a higher incidence of knee OA due to excessive knee joint load. The association between physical activity and knee OA, has not been systematically addressed in overweight and/or obese subjects and its association seems to be controversial. On the one hand, mild to non-weight-bearing physical activities have been found to be beneficial in the management knee homeostasis, the physiologic knee joint load providing an optimized environment for the joint tissues. On the other hand, excessive fast-paced physical activity with high load-joint torsion such as racquet sports, ball sports and running have been found to have an increased incidence of knee injury compared to mild-moderate exercise such as swimming, bicycling and low-impact aerobics independent of body weight.

Response: A quarter of young adults in the US have reported being unemployed during the COVID-19 pandemic. Young adults may be especially affected by employment loss as they often work in industries most adversely affected by social distancing. MedicalResearch.com: What are the main findings? Response: Among a sample of nearly 5,000 young adults age 18 to 26 in the US, we found that since March 2020, young adults who lost their job or were part of a household that experienced employment loss were more likely than those with secure employment to experience four common symptoms of anxiety and depression. This was also true of young adults who expected an employment loss in the next four weeks. The study also found that symptoms of anxiety and depression were common among the sample of young adults. In the seven days prior to the survey, 75% reported being nervous, anxious or on edge, 68% reported not being able to stop or control worrying, 67% reported having little interest or pleasure in doing things, and 64% reported feeling down, depressed, or hopeless.

Education Division of Rheumatology, Department of Medicine University of California, San Francisco MedicalResearch.com: What is the background for this study? Response: This study utilized data from the COVID-19 Global Rheumatology Alliance Provider Survey, which launched on March 25th. To date, it has collected information on over 6,000 patients with rheumatic disease diagnosed with COVID-19 from over 40 countries worldwide. As COVID-19 spread across the world in the spring, and especially within the United States, it became clear that the disease was impacting certain groups more than others. Growing attention and research began to illustrate the disproportionate burden of COVID-19 among racial/ethnic minorities in the United States. We know that racial and ethnic minorities experience a higher burden of rheumatic disease risk and severity; therefore, our group was interested in examining whether the disproportionate burden of COVID-19 also affected this susceptible population.

What are the main findings? Response: This paper describes the findings form the FOURIER study, a very large study evaluating the efficacy of evolocumab, a PCSK9 inhibitor in patients with metabolic syndrome and preexisting atherosclerotic cardiovascular disease (ASCVD) who were already being treated with statins. In this largest study of its kind of 27,000 patients we found that 60% of patients with ASCVD had metabolic syndrome. We also found that the presence of metabolic syndrome identified a higher risk of future cardiac & coronary events in these patients despite them receiving maximum tolerated doses of statin. Furthermore, study treatment with evolocumab was efficacious in reducing the increased risk during the median follow up of nearly 3 years . Unlike treatment with statins there was no risk of new-onset diabetes with evolocumab, which was generally well tolerated. What was interesting thatpatients without metabolic syndrome had much less benefit with PCSK9 inhibition. These findings suggest that the presence of metabolic syndrome can help the clinicians identify the ASCVD patients who are most likely to benefit from treatment with PCSK9 inhibitors. This will be of great help for the cost containment of therapeutic strategy as PCSK9 inhibitors as a class are still quite expensive drugs.
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.

Alzheimer's - Dementia, Author Interviews, Brain Injury, Medical Imaging, UCSF / 06.01.2020

MedicalResearch.com Interview with: [caption id="attachment_52640" align="alignleft" width="180"]William G. Mantyh, MD Clinical Fellow, UCSF Memory and Aging Center Weill Institute for Neurosciences UCSF Dr. Mantyh[/caption] William G. Mantyh, MD Clinical Fellow, UCSF Memory and Aging Center Weill Institute for Neurosciences UCSF MedicalResearch.com: What is the background for this study? Response: Similar to Alzheimer’s disease (AD) and other dementing illnesses, Chronic Traumatic Encephalopathy (CTE) is a progressive neurodegenerative condition associated with abnormally folded tau protein in the brain. CTE is thought to be caused by exposure to repetitive head trauma, and recently has been the subject of intense media coverage given the frequency of CTE found in brains of deceased former American professional football players. CTE is almost impossible to confidently diagnose during life as the symptoms are diverse and vary from patient-to-patient. Symptoms can include impairments in memory, multi-tasking, behavioral/mood regulation, and movement. As there are no blood, imaging, or other tests for this disease, one active area of research is developing a test to help doctors diagnose this condition. As tau tangles in CTE are similar in many respects to those in Alzheimer’s disease, there was hope that PET tracers that detect tau in AD might also work in CTE. Flortaucipir (FTP) is probably the most widely used tau tracer in AD. Recent work has reported some signal from FTP-PET in symptomatic former NFL players and other patients at risk for CTE (Stern et al. New Engl Jour Med 2019; Lesman-Segev et al. Neuroimage Clinical 2019). The overall signal was lower than that observed in Alzheimer’s disease, and, in lieu of correlations with post-mortem findings, it was unclear how well FTP binds to tau pathology in CTE.

Response: Our study leveraged radiation dose data from 72 facilities performing CT scans around the United States to learn more about the radiation dose used for lung cancer screening scans, as well as possible institutional predictors that might be associated with higher dose.  Currently, the American College of Radiology has recommendations for how these low-dose lung cancer screening scans should be performed. However, it is unclear how much adherence there currently is to these guidelines. Our findings indicated that there is wide variation in the distribution of radiation doses for low-dose lung cancer screening scans both within- and between facilities in our sample—in some cases this variation led to doses higher than the ACR recommendations.

What are the main findings? Response: Smoking remains the most common preventable cause of death and disability. We previously found evidence that tobacco smoke exposure in the young may lead to atrial fibrillation, the most common heart rhythm disturbance, later in life. Here we leveraged the multi-generational nature of the Framingham Heart Study to demonstrate that parental smoking was a risk factor for offspring atrial fibrillation. At least some of this relationship was explained by a greater propensity to smoke in offspring of smoking parents. These findings demonstrate a potentially new harmful effect of smoking pertinent to the most vulnerable population, our children. It also demonstrates how parental behaviors can have meaningful adverse consequences to their children decades later.

Lee Institute for Health Policy Studies University of California, San Francisco Dr. Smith-Bindman[/caption] Rebecca Smith-Bindman, MD Professor, Department of Radiology and Biomedical Imaging, Epidemiology and Biostatistics Philip R. Lee Institute for Health Policy Studies University of California, San Francisco MedicalResearch.com: What is the background for this study? Response: Medical imaging increased rapidly from 2000 to 2006. The rise in imaging can be attributed to improvements in technical aspects of imaging, strong physician and patient demand, and strong financial incentives. While imaging contributes to accurate disease diagnosis and improved treatment, imaging can also increase costs and patient harms, such as incidental findings, overdiagnosis, anxiety, and radiation exposure associated with increased risk of cancer. Potential overuse of diagnostic testing has been addressed by the American Board of Internal Medicine Foundation’s Choosing Wisely Campaign and initiatives by payers to reduce imaging through payment reductions, but there remains uncertainty in the impact of these initiatives on imaging rates.The objective of our study was to evaluate recent trends in medical imaging. Our study assessed imaging from 2000 through 2016 among individuals enrolled in diverse U.S. integrated healthcare systems and among individuals residing in Ontario, Canada and assessed changes in medical imaging utilization over time by country, health system, and patient demographic factors.

Would you describe what is meant by metagenomic sequencing? Response: Metagenomic next-generation sequencing (mNGS) is the use of technology to generate millions of sequence reads to diagnose infection sin patients by characterizing the full range of potential pathogens (bacteria, viruses, fungi, and parasites) in a single sample. Although shown to be a promising diagnostic tool for  infectious diseases in case reports and limited case series (Chiu and Miller Nature Reviews Genetics 20, 341-355 (2019)), to date the “real-life” utility of this approach for patient care has hitherto not been demonstrated.  This study is the first prospective, multi-center study of clinical mNGS testing for the diagnosis of neurological infections in acutely ill hospitalized patients presenting with meningitis and/or encephalitis.

MedicalResearch.com Interview with: [caption id="attachment_48079" align="alignleft" width="135"]Dr. Katrina Abuabara Dr. Abuabara[/caption] Dr. Katrina Abuabara, MD, MA, MSCE Department of Dermatology Program for Clinical Research, University of California, San Francisco MedicalResearch.com: What is the background for this study? Response: The wellbeing and development of children is strongly influenced by parents’ physical and psychosocial health. Parents of children with chronic illness, in particular, are susceptible to poor sleep, and previous studies have found major sleep impairments among parents of children with ventilator dependency and cystic fibrosis, but few studies have examined sleep patterns among parents of children with more common chronic illnesses like atopic dermatitis (also known as eczema).

MedicalResearch.com Interview with: [caption id="attachment_47913" align="alignleft" width="200"]Robert Avram MD MScDivision of CardiologyUniversity of California, San Francisco Dr. Robert Avram[/caption] Robert Avram MD MSc Division of Cardiology University of California, San Francisco MedicalResearch.com: What is the background for this study? Would you briefly describe what is meant by Photoplethysmography? While analyzing the heart rate data as collected using smartphones apps in the Health-eHeart study, we noticed that diabetic patients had, on average, a higher ‘free-living’ heart rate than non-diabetic patients when adjusted from multiple factors. This pushed us to analyze the signal to see if there were other features that would help differentiate diabetes patients from non-diabetes patients. By identifying these features, we saw a huge opportunity to develop a screening tool for diabetes using deep learning and a smartphone camera and flash, in order to classify patients as having prevalent diabetes/no-diabetes. Photoplethysmography is the technique of measuring the difference in light absorption by the skin in order to detect blood volume changes in the microvasculature. Most modern mobile devices, including smartphones and many fitness trackers (Apple Wathc, FitBit), have the ability to acquire PPG waveforms, providing a unique opportunity to detect diabetes-related vascular changes at population-scale.

Response: This article is about the behavioral health and burnout consequences among physician mothers who are caring for seriously ill loved ones. Our work was inspired, in part, by some of the authors’ own experiences caring for loved ones with serious illnesses while also being physician mothers themselves.  We sought to determine the proportion of physician mothers with such caregiving responsibilities beyond their patients and children and the how these additional responsibilities affected the women’s health and practice.
