MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The risks of anaphylaxis among intravenous (IV) iron products currently in use has not been assessed. Older adults have a higher risk of experiencing drug-induced anaphylaxis. Accordingly, our study objective was to elucidate the risk of anaphylaxis among older adults receiving the five frequently used IV iron products: ferric carboxymaltose, ferumoxytol, ferric gluconate, iron dextran, and iron sucrose.

MedicalResearch.com: What is the background for this study?
Response: COVID-19 disrupted hands on surgical exposure of medical students and academic centres around the world had to quickly adapt to teaching technical skills remotely. At the same time, advances in artificial intelligence (AI) allowed researchers at the Neurosurgical Simulation and Artificial Intelligence Learning Centre to develop an intelligent tutoring system that evaluates performance and provides high-quality personalized feedback to students. Because this is the first AI system capable of providing surgical instructions in simulation, we sought to evaluate its effectiveness compared with learning from expert human instructors who provided coaching remotely.

Response: Most people are aware that a lack of sleep is associated with all sorts of health issues. However, familial natural short sleeper (FNSS) individuals sleep 4-6.5 hours a night most of their live and stay healthy. We set out to determine whether natural short sleep mutations can offer protection from various diseases. We chose Alzheimer as an example to start.

MedicalResearch.com: What is the background for this study?
Response: Up to now doctors measured blood pressure (BP) on standing only in elderly people on pharmacological treatment with the purpose of detecting orthostatic hypotension. In young-to-middle-age people BP is currently measured only in the lying or the sitting posture.
Our starting point was that young borderline hypertensive people have an increased sympathetic activity and thus they might be hyperreactive to physical stimuli such as assuming the orthostatic posture which may be deleterious in the long run. This hypothesis was tested in the HARVEST, a study initiated in Italy in 1990, in which over 1200 young patients screened for stage 1 hypertension were enrolled.

MedicalResearch.com: What is the background for this study?
Response: Diabetes is associated with a poor prognosis of COVID-19. There have been raised concerns about a bidirectional relationship between diabetes and COVID-19. Recent studies raised the possibility that SARS-CoV-2 can cause diabetes. However, there is a lack of studies investigating the incidence of diabetes after recovery from COVID-19 in mild cases.
To provide more evidence, we analyzed electronic health records from 1,171 general and internal medicine practices across Germany between March 2020 and January 2021. This included 35,865 patients who were diagnosed with COVID-19. The incidence of diabetes after COVID-19 was compared with patients, who were diagnosed with an acute upper respiratory tract infection (AURI), matched for sex, age, and comorbidities including obesity, high blood pressure, high cholesterol, heart attack, and stroke.

MedicalResearch.com: What is the background for this study?
Response: Prior research has shown that people with higher polygenic risk for coronary artery disease achieve greater risk reduction with statin or other lipid lowering therapy. In general, adherence to standard guidelines for lipid lowering therapy is low - about 30% of people who should be on lipid lowering therapy are, with no correlation to their genetic risk. We set out to see whether communicating personalized risk, including polygenic risk, for coronary artery disease would drive the adoption of lipid lowering therapy.

MedicalResearch.com: What is the background for this study? How does the amount of flavanols in the study arm compare to what might be obtained in a typical diet?
Response: The COcoa Supplement and Multivitamin Outcomes Study (COSMOS) is a randomized, double-blind, placebo-controlled clinical trial that tested the effects of two promising dietary supplements on cardiovascular disease (CVD) and cancer in 21,442 older adults. Cocoa flavanols have been shown to have favorable vascular effects in small and short-term clinical trials. The 500 mg/day flavanols tested in COSMOS exceeds that readily obtained in the diet typically from cocoa, tea, grapes, and berries. Of note, flavanol content in not typically listed on food labels.
COSMOS also tested a multivitamin, the most common dietary supplement taken by US adults and previously linked with a potential modest reduction in cancer in a previous long-term trial of men conducted by our research group at the Division of Preventive Medicine at Brigham and Women’s Hospital.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Obstructive sleep apnea (OSA) affects 22 million people in the U.S. and is linked to a higher risk of hypertension, heart attacks, stroke, diabetes, and many other chronic conditions.
We have found that untreated OSA also accelerates the biological aging process, and that appropriate treatment can slow or possibly reverse the trend. Age acceleration testing involves a blood test that analyzes DNA and uses an algorithm to measure a person’s biological age. The phenomenon of a person’s biological age surpassing their chronological age is called “epigenetic age acceleration” and is linked to overall mortality and to chronic diseases.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Very little is known about the care and outcomes of patients who reach the end stages of kidney disease and do not pursue dialysis. We conducted a systematic review of longitudinal studies on patients with advanced kidney disease who forgo dialysis to determine their long-term outcomes.
We found that many patients survived several years and experienced sustained quality of life until late in the illness course. However, use of acute care services was common and there was a high degree of variability in access to supportive care services near the end of life.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Identifying early risk factors and early changes in the brain will have a major impact on future clinical and public health priorities related to the looming epidemic of dementia. Several studies based on older populations suggest mid-life is an important period to start prevention measures. To date control of blood pressure levels has been the most robust and promising candidate to target for prevention of future cognitive impairment. Although several studies have looked at levels of blood pressure and risk for cognitive impairment, it was not known whether trajectories from young adulthood to middle age studies provided additional information about risk. To investigate possible biomarkers of future risk, we chose to examine the association of the mean arterial blood pressure trajectories to indicators of pathology seen on MRI and that are associated with cognition.
We highlight the results of the mean arterial blood pressure (MAP) measure, which is an integrated measure of systolic and diastolic blood pressure.
Response: Cigarette smoking is one of the well-established causes of periodontitis, but the effect of using electronic cigarettes (e-cig), especially its long-term impact on periodontal health, is not yet clearly understood. Considering the increased popularity of e-cig use, especially among teenagers and young adults, and the known effect of high nicotine concentration in e-cigarette products, we conducted this clinical research to see if there were differences in periodontal health between e-cig users, traditional smokers, and nonsmokers. The study consisted of two visits, 6 months apart, where measures of oral and periodontal health were obtained.
Our data showed significantly greater clinical attachment loss in the e-cigarette users and cigarette smokers than in the non-smokers at both study visits. In only e-cigarette users, we observed an over 0.2 mm average increase in the clinical attachment loss after 6 months.

MedicalResearch.com: What is the background for this study?
Response: Pancreatic cancer is one of the deadliest types of cancer: although incidence rates are relatively low (only few people develop pancreatic cancer in their lifetimes), it has a high lethality, with a five year survival rate of less than ~5%. Pancreatic cancer symptoms are generally unspecific so that the disease is usually detected very late which further limits therapeutic options. In light of this, earlier detection of pancreatic cancer could dramatically improve prognosis, but there are currently no affordable and non-invasive tests available in the clinic.
For pancreatic ductal adenocarcinoma (PDAC),the most common form of pancreatic cancer, it was previously found that the oral, gut and pancreatic microbiome are risk factors and may affect prognosis .

Response: Lead is a well-established neurotoxin, particularly when exposure occurs early in life and in childhood. Associations between elevated blood lead levels and lower scores on tests of neurodevelopment and cognition are seen consistently across studies, even when examining lower levels of exposure.
While reducing exposure to lead is the primary intervention to prevent these adverse outcomes, there aren’t many interventions designed to support the neurodevelopment of children who have been exposed to lead. Some municipalities consider elevated blood lead levels as a criteria for inclusion in Early Intervention programs. Early Intervention programs are mandated under the Individuals with Disabilities Education Act and provide services for children younger than 3 years old with disabilities or developmental delays.
The objective of this study was to compare 3rd grade standardized test scores among children who had elevated blood lead levels early in life to see if children who had received Early Intervention services performed better on these tests than those who did not receive services. Using matching methods and an existing administrative data linkage of children who were born and attended public school in New York City, we observed that children exposed to lead who received Early Intervention services scored higher on standardized tests in both math and English Language arts than children exposed to lead who did not receive services.

MedicalResearch.com: What prompted you to look at the safety of peanut oral immunotherapy specifically in this patient population?
Response: Our previous research has investigated the overall safety of peanut oral immunotherapy (OIT) in preschool populations. However, we have not investigated the relationship between specific patient characteristics and the safety of OIT. Previous literature has shown that patient factors, such as age, gender, baseline sIgE levels, and atopic comorbidities have been shown to impact the safety of OIT for other food allergies and in older patients. However, no data exist on which factors predict safety of peanut OIT in preschool populations.
