Previous research indicates that children in the United States are entering puberty at younger ages. These children may be in danger of developing certain diseases, such as type 2 diabetes, later in life. A better understanding of how early life factors affect puberty development is important for combating earlier puberty onset. .

Head of Department (acting), Professor of Pharmacoepidemiology, Department of Epidemiology Research Statens Serum Institut MedicalResearch.com:  What is the background for this study?  Response: An unusually low number of extremely preterm births have been observed in some countries during the initial covid-19 lockdowns. We speculated that this could be because of fewer infections, reduced activity levels, less stress etc. These are also factors that change with the seasons, and we hypothesized that extremely preterm birth might be associated with seasonality.

MedicalResearch.com Interview with: Dr. Laurence Moss MD, PhD candidate Centre for Human Drug Research (CHDR) Department of Anesthesiology Leiden University Medical Centre (LUMC) Geert Jan Groeneveld​, MD, PhD Neurologist | Clinical Pharmacologist | Professor of Clinical Neuropharmacology CMO/CSO Centre for Human Drug Research Leiden, The Netherlands  MedicalResearch.com:  What is the background for this study?    Response: Opioid use disorder (OUD) is a major source of morbidity and mortality, and the opioid epidemic in the Unites States (but increasingly in Europe also) has been well documented and reported on by the media. The alarming rise in opioid related mortality is largely driven by the increasing use of fentanyl and fentanyl analogues, often surreptitiously mixed with heroin or other drugs such as psychostimulants or prescribed opioids. Opioid-induced respiratory depression in particular is a leading cause of opioid-related fatalities. Buprenorphine has been proven as an effective medication for the treatment of OUD. Buprenorphine is a semi-synthetic partial agonist for the opioid receptor that firmly binds to these receptors and displays only partial respiratory depressive effects, meaning it does not cause the complete cessation of breathing as is the case with other potent opioids such as fentanyl. Due to its firm receptor binding, we hypothesized that at sufficient buprenorphine receptor occupancy, the effect of fentanyl on respiration would be limited, even at high fentanyl doses. This study aimed to provide proof of principle for this hypothesis, and demonstrate whether buprenorphine could reduce fentanyl-induced respiratory depression.

Response: This study represents an international collaboration across four continents and six countries, to pool information from studies in different patient populations to generate robust information about the possible benefits of convalescent plasma in treating COVID-19. Because the study was so large and the methods so rigorous, we were able to show that while CP doesn’t benefit all patients, it may have positive effects in certain subgroups.

MedicalResearch.com Interview with: Xing Gao, MPH, lead author and doctoral candidate in Dr. Mujahid's research group Mahasin Mujahid, MS, PhD, FAHA Lillian E. I. and Dudley J. Aldous Chair in the School of Public Health Associate Professor of Epidemiology Director, Epidemiology & Biostatistics Master of Public Health Program UC Berkeley, School of Public Health MedicalResearch.com:  What is the background for this study?  What are the main findings?
  • ​​Hypertension is a major risk factor for cardiovascular diseases, and persistent racial and ethnic inequities in hypertension remain an urgent public health challenge.
  • Public health researchers need a more nuanced understanding of how structural factors contribute to these inequities, which has a direct application to improving the cardiovascular health of marginalized populations.
  • This study examined associations between racial residential segregation, a product of historical and contemporary racially discriminatory policies, and hypertension in a multi-racial cohort of middle-aged and older adults.

This is important because when child care programs close it becomes very difficult for working families to find safe, affordable alternative care. We surveyed over 6000 child care workers from across the US in May/June 2020 with a follow up survey in May/June 2021. This includes both center based and home based child care programs. One question we were interested in was what things they were doing in their programs to reduce the risk of COVID-19. We then asked whether their program closed at any time in that year because of COVID-19.

For this recommendation, the Task Force evaluated whether screening adults over the age of 50 who do not have any signs or symptoms of AFib can help prevent strokes. In its evidence review, Task Force expanded its scope to include a search for studies on portable and wearable devices such as smartphones and fitness trackers in addition to electrocardiography (ECG). Despite this consideration, the Task Force found insufficient evidence to recommend for or against screening for AFib. This is consistent with the Task Force’s 2018 recommendation.

Response: The COMPILE study is based on real-time collection of individual patient data from 8 international completed, terminated early and ongoing randomized clinical trials testing the efficacy of convalescent plasma for the treatment of hospitalized patients with COVID-19. Recruitment covered the period from March 2020 to March 2021 in Asia, Europe, North and South America. Total of 2369 patients were enrolled and data from 2341 patients were used in the analysis. COMPILE, the largest study of convalescent plasma for hospitalized COVID-19 patients to date, provided robust information on a diverse patient population, which allowed rigorous evaluation of questions related to convalescent plasma efficacy. The main findings are that convalescent plasma might have only a moderate efficacy on average, but that there is a huge heterogeneity in the benefits for individual patients.

Although there has been a lot of discussion about vaccine hesitancy as a barrier to achieving high rates of COVID-19 vaccination, there have been few studies of changes in hesitancy - or how it might vary across groups. As COVID-19 vaccines were becoming available in the US there was a lot of discussion about worrisome rates of vaccine hesitancy, particularly among communities of color. Our team suspected, however, that these high rates might be short-lived, and that Black Americans in particular might become willing to use COVID-19 vaccines after a short period of time - as they became reassured that they would be safe, effective, and protect communities.

Response: More than 192 million people ages 12 years and older in the U.S. received at least one dose of mRNA COVID-19 vaccines from December 2020 through August 2021. From this population, VAERS (the Vaccine Adverse Event Reporting System) received 1,991 reports of myocarditis,  1,626 of which met the case definition of myocarditis. Rates of myocarditis were highest following the second dose of an mRNA vaccine among males aged 12–15 years (70.7 per million doses of Pfizer), 16-17 years (105.9 per million doses of Pfizer), and 18–47 years (52.4 and 56.3 per million doses of Pfizer and Moderna, respectively). Of those with myocarditis, the median age was 21 years and the median time from vaccination to symptom onset was two days. Males accounted for 82% of patients for whom sex was known. Approximately 96% were hospitalized, 87% of whose symptoms had gone away by the time they were discharged from the hospital. Non-steroidal anti-inflammatory drugs (589/676, 87%) were the most common treatment.

Response: Management of type 1 diabetes is challenging in very young children, due to their high variability of insulin requirements and unpredictable eating and activity patterns. As a result, many young children do not meet the recommended glycemic targets, or only maintain recommended glycemic control with extensive caregiver input. This in turn leads to high management burden and reduced quality of life for the whole family. While the increasing use of continuous glucose-monitoring devices and insulin-pump therapy has led to reductions in the incidence of severe hypoglycaemia and diabetic ketoacidosis, and has been accompanied by modest improvements in glycemic control, the burden of management has remained high. Hybrid closed-loop systems (also called an artificial pancreas), in which an algorithm automatically adjusts insulin delivery on the basis of real-time sensor glucose levels, may address ongoing challenges in this age group. However, to date hybrid closed-loop studies involving very young children have been small and of short duration and the efficacy and safety of longer term use of a closed-loop system, as compared with standard therapy, was unclear.   To address this knowledge gap, we compared 16-week use of the Cambridge closed-loop algorithm with sensor-augmented pump therapy in children aged 1 to 7 years with type 1 diabetes in a multi-national randomised crossover study.

This affords the opportunity to analyse ‘historical’ cohorts covering a period of important socio-demographic, economic, and educational change in the UK from which current and emerging trends may be identified and examined. Drawing on our previous proof-of-concept study, we investigated whether there were differences between childhood-onset versus adult-onset myopia in temporal trends in both frequency and severity and in associations with key environmental factors.

Carver College of Medicine University of Iowa Dr. Bell[/caption] Edward Bell, MD Professor of Pediatrics-Neonatology Vice Chair for Faculty Development, Stead Family Department of Pediatrics Roy J. and Lucille A. Carver College of Medicine University of Iowa MedicalResearch.com: What is the background for this study? Response: The National Institute of Child Health and Human Development, a branch of the National Institutes of Health (NIH), has supported the Neonatal Research Network (NRN) since 1986. The NRN, a group of US academic centers, is tasked with conducting research to improve the treatment and health outcomes of premature and critically-ill babies in US neonatal intensive care units (NICUs). Every few years, the NRN publishes reports on the survival rates and outcomes of surviving extremely premature babies, those born before 28 weeks of gestation. These reports help us to judge progress in the care and outcomes of these infants. This paper is the 9th in this series of reports but the first that includes not only survival and in-hospital outcomes but also outcomes at 2 years of age.

MedicalResearch.com Interview with: Laura Rupprecht, PhD Postdoctoral Fellow Kelly L Buchanan The Laboratory of Gut Brain Neurobiology Duke Medicine – GI Diego V. Bohórquez PhD Associate Professor in Medicine Duke Institute for Brain Sciences Durham, NC MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: In 2018, my laboratory discovered that a cell type in the gut epithelium synapses with the vagus nerve, the nerve which connects the gut and the brain. These gut cells are called neuropod cells. Neuropod cells transduce sugar within milliseconds using the neurotransmitter glutamate. Since then, we have been interested in defining how this rapid communication between neuropod cells and the brain regulates behavior. – Diego Bohórquez Over a decade ago, it was shown that the gut is the key site for discerning sugar and non-caloric sweetener. But the specific cell in the gut that underlies this effect was unknown. – Kelly Buchanan

MedicalResearch.com Interview with: Kassandra L. Munger Sc.D. Senior Research Scientist Alberto Ascherio MD Dr.P.H. Professor of Epidemiology and Nutrition Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: An infectious cause of MS has been hypothesized for decades. Research over the past 20 years conducted by our group and others has strongly suggested a role for EBV infection including that EBV-negative individuals have a near zero risk of developing MS, having a history of infectious mononucleosis (caused by EBV infection) increases the risk of MS 2-fold, and healthy individuals have higher risks of MS with higher antibody levels against EBV antigens.  Ideally, to prove causality a randomized clinical controlled trial would be conducted; however, this not a feasible approach in this case. Given that nearly 95% of the adult population is infected with EBV and MS is a rare disease, we utilized the Department of Defense Serum Repository which stores over 60 million serum samples from over 10 million US Military active duty personnel. From this large resource, we were able to identify a cohort who were EBV negative when they joined the military and we followed them for whether they had a primary infection with EBV and then for who developed MS.

Response: Mortality among people with diabetes, and how it changes over time, is an important indicator of quality of and access to health care. However, population level trends in mortality among people with diabetes are inadequately described. The establishment of national diabetes registers, health insurance data and administrative data has allowed the examination of mortality among those with diabetes at a granular level which has been previously not possible. This has allowed us to examine whether global efforts in regards to diabetes care over the last couple of decades have been effective.

Response: During the early stages of the global 2019 coronavirus disease (COVID-19) pandemic, children represented fewer than 5% of reported cases.  However, children now represent a significant percent of all new COVID-19 cases.  Similarly, pediatric hospitalizations due to COVID-19, are now at an all-time high.  Although COVID-19 is generally mild in children, severe outcomes and death do occur.  The risk of severe outcomes among SARS-CoV-2 infected children is poorly understood with estimates varying considerably between study designs, settings, and regions.  Studies generally include large administrative databases (i.e. community based), hospitalized populations, and children admitted to the intensive care unit (ICU). Identified risk factors for severe COVID-19 in children have included young (i.e. 1-3 months) or old (15-18 years) pediatric age group, male sex, and pre-existing medical condition.  However, data from large prospective cohort studies which include children with early or mild stages of disease seeking emergency department (ED) care are lacking. To address this knowledge gap we sought to quantify the frequency of and risk factors for severe outcomes in SARS-CoV-2 infected children enrolled in a prospective ED-based cohort study.

Kishan, MD Assistant Professor, Department of Radiation Oncology Vice-Chair of Clinical and Translational Research Department of Radiation Oncology at UCLA MedicalResearch.com: What is the background for this study? Response: We know from epidemiologic studies that  Black men are more likely to be diagnosed with and die of prostate cancer than White men. Recent studies hinted that Black men had better oncological outcome (such as prostate cancer specific mortality and overall survival) responding to systemic therapy for advanced prostate cancer (e.g. cancer that has spread or metastasized to other parts of the body). The question we were trying to answer in this study is: is there a difference in outcomes between Black and White men with localized prostate cancer (cancer that has not spread) receiving definitive radiotherapy enrolled in clinical trials?

Response: Racial inequities are pervasive in our country, and cardiovascular therapeutics with proven benefit have been shown to be underutilized among Black and Latinx patients. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), a recommended treatment option for glycemic control in patients with diabetes, have recently emerged as a cardioprotective therapy as multiple large randomized clinical trials have shown they prevent cardiovascular events among patients with Type 2 Diabetes (T2D), particularly patients with established atherosclerotic cardiovascular disease (ASCVD). Given this, they are now recommended therapy for patients with diabetes and established or high risk of ASCVD. Given the known inequitable utilization of other therapies, along with the known higher burden of diabetes and cardiovascular disease among Black patients, the aim of this study was to evaluate the uptake of GLP-1 RA as well as for inequities in utilization.

What are the main findings?  Response: Sickle cell disease is caused by a point mutation in the beta-globin gene of hemoglobin  resulting in the production of abnormal hemoglobin which leads to formation of sickle-shaped RBC under conditions of low oxygen. Sickle cell disease affects about 100,000 patients in the US which are predominantly African  American. The only curative approach is to perform an allogeneic bone marrow transplant which is however fraught with significant treatment-related risks if a matched sibling donor is not available. The current study describes the successful application of a novel gene therapy  to treat patients with sickle cell disease. The strategy is based on a gene-addition approach to introduce the genetic information for a Hemoglobin F-like molecule termed HgAT87Q into hematopoietic stem cells. The expression of this novel  hemoglobin prevents polymerization of HgbS  and has now been demonstrated to prevent the occurrence of vaso-occlusive pain crises in sickle cell disease patients.

What are the main findings? Response: In 2019, the President signed the Advancing American Kidney Health executive order, which included provisions to increase the use of home dialysis and kidney transplant for Americans living with kidney failure. To carry out this vision, the Centers for Medicare & Medicaid Services (CMS) developed the ESRD Treatment Choices (ETC) payment model, which uses financial incentives and penalties to incentivize dialysis facilities to pursue home dialysis or kidney transplant for their patients. Transplant and home dialysis are optimal care for people with kidney failure, but there are social and clinical reasons that patients with high social risk (such as those exposed to racism, poverty, or housing instability) may not be candidates for these treatments. This means that facilities which serve a large number of patients with high social risk might be disproportionately penalized by this new payment model. Using data immediately prior to the implementation of the ETC model, we found that dialysis facilities that serve high proportions of patients with high social risk have lower rates of home dialysis and kidney transplantation than facilities that care for lower proportions of such patients.

MedicalResearch.com Interview with: [caption id="attachment_58542" align="alignleft" width="181"]Ashish Thakrar, MD Internal Medicine & Addiction Medicine National Clinician Scholars Program University of Pennsylvania Dr. Thakrar[/caption] Ashish Thakrar, MD Internal Medicine & Addiction Medicine National Clinician Scholars Program University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: About 1.8 million Americans are currently incarcerated, more than any other country in the world per capita. Of those 1.8 million, about 1 in 7 suffers from opioid addiction, putting them at high risk of overdose and death, particularly in the weeks following release. Opioid use disorder is a treatable condition, particularly with the medications buprenorphine or methadone, but historically, prisons and jails have not offered treatment. Over the past five years, a few states and municipalities have enacted policies to provide access for OUD treatment. We examined whether these policies were actually improving access to treatment.
