MedicalResearch.com Interview with: [caption id="attachment_52838" align="alignleft" width="100"]Dr. Paul Young Dr. Paul Young[/caption] Dr. Paul Young MBChB, BSc (Hons), FCICM Medical Director of the Wakefield Hospital ICU Head of the Intensive Care Research Unit Wellington Hospital MedicalResearch.com: What is the background for this study? Response: Proton pump inhibitors (PPIs) are among the most widely prescribed drugs in the intensive care unit (ICU) in the world.   Many, if not most, prescriptions of PPIs in the ICU are for stress ulcer prophylaxis.  Although PPIs are used most widely for this indication, histamine-2 receptor blockers (H2RBs) are used in preference to PPIs in some ICUs.  This practice variation, which appears to be largely dependent on clinician preference rather than based on patient-specific factors, has continued for decades.  The PPIs vs. H2RBs for Ulcer Prophylaxis Therapy in the Intensive Care Unit (PEPTIC) trial results raise the possibility that PPIs, the most commonly used medicines for stress ulcer prophylaxis, may be responsible for a clinically important increase in the risk of death that, in global health terms could equate to many tens of 1000s of deaths per year.

Harrison MD Chair and Professor of Surgery Chief, MIS Bariatric & General Surgery University of Pittsburgh Medical Center Dr. Courcoulas[/caption] Anita P. Courcoulas MD, MPH, FACS Anthony M. Harrison MD Chair and Professor of Surgery Chief, MIS Bariatric & General Surgery University of Pittsburgh Medical Center  MedicalResearch.com: What is the background for this study? Response: Fewer published studies in bariatric surgery address long term adverse outcomes or problems that can occur after different operations.  In addition, a lack of standardized reporting of potential adverse events limits the understanding of these issues. This paper results from one of the largest studies of bariatric surgery ever undertaken and includes both gastric bypass and gastric sleeve, the 2 most common operations performed in the U.S. and worldwide at the current time.  This study leverages large data sets from the electronic health record linked to insurance claims and death indices.  This is real-world data coming from a population-based cohort of 33,560 adults at 10 sites in 4 clinical data research networks throughout the U.S., so it may be different from data that accrues from a longitudinal observational study or randomized trial.  Patients and other important stakeholders in bariatric surgery were critical to the design, conduct, and dissemination of results from this study.

Response: Left Ventricular assist devices meaningfully prolong survival in patients with heart failure who are no longer responsive to guideline-directed medications. The MOMENTUM 3 trial tested a new generation device, the HeartMate 3 pump, to a more commonly used pump, the HeartMate II device. This trial showed the superiority of the new heart pump and found that survival free of a disabling stroke or need to place a second pump is improved considerably. In this prespecified analysis of the trial, we compared patients who were considered as eligible for transplantation to those considered ineligible for heart transplantation. We showed that these categories are associated with similar superiority of the HeartMate 3 pump compared to the control pump despite the categorization into these discrete buckets.

Response: Medicare provides hospital ratings for all Medicare-certified hospitals in the U.S. based on quality metrics, including mortality, patient experience, hospital readmissions, and others. While ratings are important for comparing hospitals, there's been some concern that some of these quality metrics are outside a hospital's control, especially for hospitals taking care of vulnerable or socially complex patient populations. Take "timeliness of care" as a quality metric, for instance--this measure includes emergency room wait times. But in places that are medically underserved and have very few emergency rooms, these wait times will inevitably be much higher. What this means is that hospitals taking care of medically underserved populations end up getting lower quality ratings, even though they're addressing health disparities by filling an access gap.

Response: There are concerns that robotic surgery is increasing for common surgical procedures with limited evidence and unclear clinical benefit. Prior studies describing the use of robotic surgery relied upon claims or billing data to identify robotic operations from laparoscopic or open ones. This may lead to inaccuracies as claims data may not provide specific codes for robotic operations.

Response: We know that patients with severe mental disorders such as schizophrenia, bipolar disorder and major depression have shorter life span than the rest of the population, largely due to comorbid cardiovascular diseases. The increased risk seems related to lifestyle including diet and physical activity and medicines, while the mechanisms are not fully understood. Different studies have shown increased weight (high body mass index) in many people with mental disorders. Yet very little is known about genetic variants jointly in influencing major psychiatric disorders and body mass index. Thus, we investigated if there are overlapping genetic risk variants between body mass index and the mental disorders schizophrenia, bipolar disorders and major depression.

What are the main findings? Response: Triple negative breast cancer is an aggressive form of breast cancer that often requires chemotherapy. In this study we provided neoadjuvant chemotherapy with or without a PARP inhibitor and showed that many women who were originally ineligible for breast conservation (lumpectomy) became eligible after treatment. If lumpectomy was tried it was usually successful.  Many more women in the US compared to Europe and Asia chose mastectomy when lumpectomy was an option even when genetics is negative.

MedicalResearch.com Interview with: Niklas Worm Andersson, MD Department of Clinical Pharmacology, Copenhagen University Hospital Bispebjerg and Frederiksberg, Copenhagen NV, Denmark MedicalResearch.com: What is the background for this study? What is Podophyllotoxin used for? Response: Podophyllotoxin is an antimitotic agent primarily used in the local treatment of anogenital warts, which are among the most prevalent sexually transmitted diseases worldwide. Most women affected by anogenital warts are of childbearing age and during pregnancy, they may become symptomatic, enlarge, or multiply. While podophyllotoxin is part of first-line treatment of anogenital warts for the non-pregnant population, it is contraindicated during pregnancy. Fetal safety data are limited and to our knowledge, no previous human data exist to help inform on this issue.

Nonfatal opioid overdose has been identified as a potential touchpoint with the healthcare system when individuals can be drawn into treatment, yet very little is known about health care use following opioid overdose in youth. We were interested in figuring out the extent to which adolescents and young adults are receiving evidence-based treatment after an opioid overdose.

Response: The US Centers for Disease Control and Prevention has projected a drop in the number of overdose deaths for 2018; the first reported decline since 1990. They cite a decrease in prescription opioid deaths as the leading contributor to the overall reduction, but caution that deaths associated with synthetic opioids, primarily fentanyl, as well as stimulants appear to be increasing. In 2019, we reported a 798% increase in urine drug test positivity rates for nonprescribed fentanyl among results positive for methamphetamine and an 1850% increase among results positive for cocaine. In an effort to conduct ongoing surveillance of the polysubstance use landscape and help characterize these evolving trends in a more timely manner, we examined our UDT data as close to real-time as possible to observe trends in positivity for methamphetamine, cocaine, and heroin, with and without illicit fentanyl.

Pediatric Endocrinologist, Joslin Diabetes Center Assistant Professor of Pediatrics, Harvard Medical School Boston, MA 02215 MedicalResearch.com: What is the background for this study? Response: The concept that a mother's nutrition prior to and during pregnancy is important for health outcomes in the offspring is now well accepted. For example, women intending to get pregnant must take prenatal vitamins, and are encouraged to attain a healthy weight before conception. However, much less is known about how a father's nutritional status may influence childhood health outcomes.  Based on studies in animals, exposure to undernutrition, high-fat diet, or stressful experiences in fathers can result in increased risk of obesity and diabetes in the offspring. These effects are mediated in part by epigenetic mechanisms (i.e. changes in gene expression due to differences in DNA methylation, histones, or other non-genetic mechanisms).

Response: The composition of the U.S health care system is shifting; between 2001 to 2016 the number of Catholic-owned or affiliated health facilities grew by 22% in contrast to the overall number of acute care hospitals that decreased by 6% and the number of other nonprofit religious hospitals that decreased by 38%. This is relevant as Catholic health care systems enforce religious directives that restrict many aspects of reproductive care and certain aspects of end-of-life care.  Yet little is known about the extent to which U.S. patients consider religious affiliation when selecting a health care facility.

Dr. Moline[/caption] Margaret Moline, PhD Lemborexant International Program Lead and Global Medical Lead Executive Director, Neurology Business Group Eisai, Inc.  MedicalResearch.com: What is the background for this study? This study, called SUNRISE 1, is one of two pivotal Phase 3 studies in the lemborexant clinical development program that supported the recent FDA approval of DAYVIGO (lemborexant).
  • On December 20, the U.S. Food and Drug Administration (FDA) approved DAYVIGO (lemborexant) 5 mg and 10 mg, an orexin receptor antagonist indicated for the treatment of adult patients with insomnia, which is characterized by difficulties with sleep onset and/or sleep maintenance.1
  • DAYVIGO will be commercially available following scheduling by the DEA, which is expected to occur within 90 days.
  • SUNRISE 1 was a one-month, randomized, double-blind, placebo- and active-controlled, multi-center, parallel-group clinical trial in adult female patients age 55 and older and male patients 65 years and older who met DSM-5 criteria for insomnia disorder. Patients were randomized to placebo (n=208), lemborexant 5 mg (n=266) or 10 mg (n=269), or active comparator (n=263) once nightly.1
  • The primary efficacy endpoint was the mean change in log-transformed latency to persistent sleep (LPS; defined as the number of minutes from lights off to the first 10 consecutive minutes of non-wakefulness) from baseline to end of treatment (Days 29/30), as measured by overnight polysomnography (PSG) monitoring.1
  • The pre-specified secondary efficacy endpoints in Study 2 were the mean change from baseline to end of treatment (Days 29/30) in sleep efficiency (SEF) and wake after sleep onset (WASO) measured by PSG.1
  • SUNRISE 1, lemborexant 5 mg and 10 mg demonstrated statistically significant superiority on the primary efficacy measure, LPS, compared to placebo. lemborexant 5 mg and 10 mg demonstrated statistically significant improvement in SEF and WASO compared to placebo.1
  • The effects of lemborexant at the beginning of treatment were generally consistent with later timepoints.

Response: Approximately 1 in 2 women and 1 in 5 men aged 50 years or older will suffer from an osteoporotic fracture in their remaining lifetime. Hip fracture is the most serious type of osteoporotic fracture with an approximately 30% risk of death in the year following a hip fracture. Vitamin D is essential for optimal musculoskeletal health by promotion of calcium absorption, and mineralisation of osteoid tissue formation in bone and maintenance of muscle function. Low vitamin D status causes secondary hyperparathyroidism, bone loss and muscle weakness. Observational studies have reported that lower blood concentrations of vitamin D are associated with higher risks of falls and fractures. Combined supplementation with 800 IU/day vitamin D and 1200 mg/day calcium has been recommended for prevention of fractures in older adults living in institutions and in those with low vitamin D status. However, previous trials and meta-analyses of vitamin D alone, or in combination with calcium for prevention of fracture in either community-dwelling or general population settings reported conflicting results, with some reporting protective effects against fractures, but others demonstrated no beneficial effects. However, most of the previous trials had only limited power to detect differences in risk of fracture predicted by the observational studies, largely because of a combination of small sample size, relatively low equivalent daily doses of vitamin D, intermittent dosing regimens (>1 month), and short duration of follow-up. In addition, interpretation of the results of previous meta-analyses of such trials is complicated by use of variable inclusion criteria, inappropriate statistical methods, inclusion of multiple small trials with very few fracture events, in addition to failure to report achieved differences in blood 25(OH)D concentrations. We summarised the available evidence to guide clinical practice and future research, by conducting parallel meta-analyses of:
  • (i) observational studies of risks of fracture associated with prolonged differences in blood concentrations of 25(OH)D;
  • (ii) randomised trials of vitamin D alone versus placebo or no treatment for prevention of fracture; and
  • (iii) randomised trials of calcium and vitamin D versus placebo or no treatment for prevention of fracture.In addition, we reviewed the design of the ongoing randomised trials assessing the effects of higher doses of vitamin D alone or in combination with calcium for prevention of fracture.

Meister Child Health Evaluation and Research Center University of Michigan Dr. Kao-Ping Chua[/caption] Kao-Ping Chua, MD PhD Assistant Professor, Department of Pediatrics Susan B. Meister Child Health Evaluation and Research Center University of Michigan MedicalResearch.com: What is the background for this study? Response: Opioids are frequently prescribed to adolescents and young adults aged 12-21 years – in a recent study, 1 in 8 patients in this population were prescribed opioids during the year. At the same time, almost 30% of the 3000 opioid-related overdose deaths in 2016 among adolescents and young adults involved prescription opioids. Given the frequency of opioid prescribing and the risk of overdose, it is important to understand how to prescribe opioids safely to adolescents and young adults. However, there have been few studies that examine which opioid prescribing patterns are associated with prescription opioid overdose in adolescents and young adults. Prior studies examining these patterns have focused on older adults, particularly U.S. Veterans, so the generalizability of these findings to younger populations is unclear.

Focusing solely on sport-related concussion may result in an underestimation of the underlying incidence and prevalence of concussion in the general population and leads to the widely held perception that most concussions are sport-related. An understudied population at risk for concussion are United States undergraduate college students.

However, no prior study had studies the associations between ultra-processed food and Type 2 diabetes risk. We suspected that we would find these associations since some components of ultra-processed foods light have metabolic interactions with human health (some food additives for instance).

Response: Nailfold capillaroscopy (NFC), long used in rheumatology is a new approach to investigation of glaucoma. Posterior to the nailbed and just anterior to the proximal nailfold is the cuticle, which has no structural elements visible to the naked eye. NFC is a non-invasive imaging modality that provides a highly magnified view of the capillaries at the nailfold of digits. It has also been used in ophthalmology to show morphological changes at the nailfold capillaries of POAG and XFG/XFS patients, helping to confirm the systemic nature of these diseases. [caption id="attachment_52469" align="alignleft" width="400"]Nailfold Capillaroscopy Dr. Ritch Nailfold Capillaroscopy / Dr. Ritch[/caption] With nailfold capillaroscopy, an extensive array of capillaries can be seen greatly enlarged on a monitor screen. Capillary loops can be imaged, stored, recorded with videoscopy, and blood flow actively imaged and measured.. The first series of papers on glaucoma were written by Prof Josef Flammer’s group at the turn of the 21st century, looking at vasospasm, blood flow in normal-tension and high-tension glaucoma, and relating ocular blood flow alterations to systemic vascular regulation and relating laser Doppler flowmetry to NFC. Studies from Korea later associated nailbed hemorrhages and loss of nailbed capillaries to the presence of optic disc hemorrhages and investigated correlation of of heart rate variability with visual field defects and nailfold capillaroscopy. Studies by our group began with the publication in 2015 of a paper by Pasquale et al (Nailfold Capillary Abnormalities in Primary Open-Angle Glaucoma: A Multisite Study. IOVS;56:7021) using NFC video microscopy, associating dilated capillaries, avascular zones, and hemorrhages with primary open-angle glaucoma. Successive manuscripts and presentations at conferences have indicated differences between capillary loop patterns in high-tension and normal-tension POAG and exfoliation syndrome/exfoliation glaucoma. Our goal in this paper was to compare nailfold peripheral blood flow in XFG, which had not previously been compared to control subjects using NFC. We explored the peripheral blood flow at the nailfold of patients with high-tension glaucoma, normal-tension glaucoma, exfoliation glaucoma (XFG) and compared it to control subjects further evaluate the possible differences between these glaucoma entities. We examined the morphology and extent of nailfold capillary loops, vascular tortuosity, blood flow, and nailfold hemorrhages.

The purpose of our study was to determine the risk of non-cutaneous and cutaneous cancers in patients with atopic dermatitis compared to the general population (i.e. without AD).

Response: HIV pre-exposure prophylaxis (PrEP) is being rolled out globally. This will protect many people from HIV, however PrEP does not protect against other sexually transmitted infections (STI). So we wanted to quantify how much STIs are in PrEP users as a means to advocate to strengthen sexual health services in these settings where PrEP is being offered.
