ADHD, Author Interviews, JAMA, Pediatrics, University of Michigan / 18.04.2023

MedicalResearch.com Interview with: Sean Esteban McCabe, PhD Director, Center for the Study of Drugs, Alcohol, Smoking and Health Department of Health Behavior and Biological Sciences University of Michigan School of Nursing Ann Arbor, MI MedicalResearch.com: What is the background for this study? Response: Prescription stimulant therapy for ADHD helps millions of people, including in my own family, and students, friends and colleagues. It's critical to balance the need for access to these medications while reducing the risk for misuse. This is more important than ever now because there have been recent increases in the prescribing of stimulant therapy for ADHD. There is a need to understand the prevalence of stimulant therapy for ADHD and prescription stimulant misuse in U.S. middle and high schools. (more…)
Alzheimer's - Dementia, Author Interviews, Brigham & Women's - Harvard, Gender Differences, JAMA, Menopause / 03.04.2023

MedicalResearch.com Interview with: Rachel Buckley, PhD Assistant Professor Department of Neurology Massachusetts General Hospital/Harvard Medical School MedicalResearch.com: What is the background for this study? Response: While a fair amount of studies have focused on the effects of menopause and hormone therapy on risk of dementia, far fewer studies have tested their association with the biology of Alzheimer’s disease, namely amyloid and tau. This is critical to know given that it still remains unclear what might be the driving mechanism of the menopause transition on risk for dementia. This is what our study set out to investigate. This study is one of the first to report a link between women’s age at menopause and tau in the brain, which we measured with positron emission tomography neuroimaging. We found that in multiple areas of the brain that tend to be most likely to show higher tau in women than men, women with earlier age at menopause and elevated levels of amyloid showed higher levels of tau than those who reported an average age at menopause (~50 years in the United States). Women who reported premature menopause (<40 years at menopause onset) exhibited a much higher risk of tau in the brain. This supports the notion that longer exposure to estrogen throughout life might be protective against Alzheimer’s disease. (more…)
Author Interviews, Exercise - Fitness, Mental Health Research / 20.03.2023

MedicalResearch.com Interview with: Dr Helen Keyes  PhD, AFBPsS, SFHEA Head of School  Psychology & Sport Science Anglia Ruskin University Cambridge MedicalResearch.com: What is the background for this study? What types of sporting events? Response: The data were collected as part of a large government study looking at a range of measures on health and activities across the UK population. Our study honed in on aspects of wellbeing – life satisfaction, loneliness, happiness, anxiety, a sense that life is worthwhile – as well as whether participants had attended a live sporting event in the last year. The data collected did not differentiate between different types of sport – the positive effects that we report for wellbeing are population-wide across a whole range of sports, from attending a local football match all the way up to elite sporting events.

Author Interviews, Depression / 05.03.2023

Editor's note: This piece discusses suicide. If you have experienced suicidal thoughts or have lost someone to suicide and want to seek help, you can contact the Crisis Text Line by texting "START" to 741-741 or call the Suicide Prevention Lifeline at 800-273-8255. MedicalResearch.com Interview with: Alexia Aguilar Geisinger Commonwealth School of Medicine Scranton, PA     MedicalResearch.com: What is the background for this study? Response: Traditional antidepressants like Zoloft and Lexapro have three major drawbacks.
  • First, they have a therapeutic lag and take at least a couple weeks to begin to improve mood.
  • Second, they do not work very well for many patients with only about one-third experiencing a remission.1
  • Third, they carry a Food and Drug Administration black box warning for increasing the risk of suicide in young-adults. There is tremendous enthusiasm for the anesthetic ketamine and esketamine because they overcome all three of these limitations. The brand name of esketamine is Spravato. Spravato received conditional approval from the FDA in March of 2019 as a nasal spray for treatment resistant depression or acute suicidality.  The goal of this study was to examine prescriptions for ketamine and esketamine in 2019 and 2020.

Alzheimer's - Dementia / 03.03.2023

Dementia is a condition that affects many older adults aged 65 years and older but is increasingly being diagnosed in much younger people. It is a tragic disease as the personality of the sufferer changes, they struggle to identify close family members, and there is a profoundly sad loss of dignity as the disease progresses. Medical researchers are very active in undertaking experiments to find better ways of early diagnosis and treating patients more effectively. We look at the more recent research in this regard.

Improved Digital Markers

Scientists have found a new method to predict dementia before its onset or while it is still mild. This allows those who are positively identified to make lifestyle changes to stay healthy for longer and to begin preparing for special care when they can no longer look after themselves. The research tests comprised a study of driving behaviors. This was a longitudinal study. It had a 96% accuracy and considered 200 driving elements. Just under 3000 test subjects participated in the study, which took place in five US states. All the participants were still driving their own vehicles as a way of retaining their independence as they entered the older age stages of life, with everyone being between 65 and 79 years of age. Eighty-five percent of this age group were found to still be driving at this stage of life. None had signs of cognitive decline. Follow-up of the participants took place three years after the testing phase. Sixty-one participants had gone on to develop Alzheimer’s disease, some cognitive decline, or other types of dementia. The researchers compared their results against two other popular methods (logistic regression and random forests) of predicting dementia and found that their test had a 6-10% greater accuracy than the rest. Two aspects of driving that were especially useful for predicting future dementia were how many times drivers braked hard with 0.4 g or greater deceleration and the ratio of right and left turns. Regarding the latter, older people found it less risky to turn right rather than left. Early warning of possible dementia later in life is essential to preparing for increasing levels of care, from overnight, to 24/7. Check out this guide if you want to know more about what is overnight care. Many dementia patients with mild impairment may start with this form of assistance. A bit of help when needed can allow the person to store their energy for greater independence in intimate activities like bathing. (more…)
Aging, Alzheimer's - Dementia, Author Interviews, Supplements / 01.03.2023

MedicalResearch.com Interview with: Christopher R. Martens PhD Assistant Professor Director, Delaware Center for Cognitive Aging Research Department of Kinesiology & Applied Physiology University of Delaware Newark, DE MedicalResearch.com: What is the background for this study? Response: One of the main issues with Alzheimer's disease is an impaired ability to make energy in the brain. NAD+ is critically involved in the creation of energy within cells and there is strong evidence that nicotinamide riboside (NR), a precursor to NAD+, can restore brain function in mice that exhibit similar characteristics as people with Alzheimer's disease. We had previously studied the effects of NR in healthy older adults and wanted to see whether it is even capable of getting into brain tissue. We used remaining blood samples from our original study and measured the amount of NAD+ within tiny "vesicles" in the blood that we are quite confident originated from the brain and other neural tissue (more…)
Alzheimer's - Dementia, Author Interviews, Genetic Research, Race/Ethnic Diversity, Stanford / 21.02.2023

MedicalResearch.com Interview with: Yann Le Guen, Ph.D. Assistant Director, Computational Biology Quantitative Sciences Unit Stanford Medicine MedicalResearch.com: What is the background for this study? Response: Apart from aging, the strongest contributing factor for late-onset Alzheimer’s disease is a specific allele of the APOE gene, which has three common alleles E2, E3, and E4. While E3 is the most common and considered as the reference, E2 is associated with decreased Alzheimer’s disease risk and E4 is associated with increased Alzheimer’s disease risk. Notably the prevalence of E4 among Alzheimer’s patient is high with about 60% of these carrying at least one E4 allele, while solely about 30% Americans carry one E4 allele. It’s worth emphasizing that individuals with an E4/E4 genotype have an exponential increased in their risk to develop AD (10 times as likely than the reference E3/E3 genotype), and individuals with an E3/E4 genotype have an intermediate risk. Though, most studies of Alzheimer’s disease genetic have been focused on European ancestry, this is beginning to change thanks to NIH’s efforts to fund more studies in non-European ancestry individuals. Our study built on these recent efforts to assess the Alzheimer disease risk associated with an APOE variant (R145C) present in about ~4% African Americans, but extremely rare in Europeans. (more…)
Author Interviews, Autism, JAMA, Pediatrics, UCSD / 08.02.2023

MedicalResearch.com Interview with: Karen Pierce, Ph.D. Professor, Department of Neurosciences, UCSD Co-Director, Autism Center of Excellence, UCSD MedicalResearch.com: What is the background for this study? Response: The mean age of ASD diagnosis and eventual treatment remains at ~52 months in the United States1 - years beyond the disorder’s prenatal origins2, and beyond the age when it can be reliably diagnosed in many cases3. Currently the only way to determine if a child has autism spectrum disorder (ASD) is to receive a developmental evaluation from an experienced clinician (usually a licensed clinical psychologist). There are often long waiting lists, and only a small number of clinicians have the experience required to make early-age (i.e., between 12-36 months) diagnoses of ASD. Thus, there are many places in the country as well as world wide wherein children wait months or years to receive a formal diagnosis due to a lack of available expertise. Moreover, diagnostic evaluations are expensive and usually cost the parent and/or insurance approximately ~$2,000 or more per evaluation.  Finally, clinical evaluations usually take between 2-3 hours to complete and result in fatigue for both the parent and toddler. Eye-tracking, which generates biologically-relevant, objective, and quantifiable metrics of both visual and auditory preference profiles in babies and toddlers in just minutes, is a technology that can dramatically change how ASD is diagnosed.

Contact a qualified medical professional before engaging in any physical activity, or making any changes to your diet, medication or lifestyle,   MedicalResearch.com Interview with: Alison R. Huang, PhD MPH Senior Research Associate Cochlear Center for Hearing & Public Health Department of Epidemiology Johns Hopkins Bloomberg School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Hearing loss is a critical public health issue affecting two-thirds of older adults over 70 years old. There is growing understanding of a strong link between hearing loss and dementia, which impacts millions of Americans. Our main findings are that in a nationally representative sample of older adults in the United States from the National Health and Aging Trends Study, every 10 decibel increase in hearing loss was associated with 16% greater prevalence of dementia, such that prevalence of dementia in older adults with moderate or greater hearing loss was 61% higher than prevalence in those with normal hearing. We also found that in older adults with moderate or greater hearing loss, hearing aid use was associated with a 32% lower prevalence of dementia. (more…)
Accidents & Violence, Aging, Author Interviews, BMJ, Brain Injury, Brigham & Women's - Harvard, Exercise - Fitness / 15.12.2022

MedicalResearch.com Interview with: Rachel Grashow PhD Research Scientist Department of Environmental Health Football Players Health Study at Harvard University Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: Anecdotally, we heard from former NFL players that they felt older than their chronological age. At the same time, doctors and medical care providers treating former players also observed that players appeared clinically older in some health domains. These observations motivated us to ask:  despite superior fitness and success as young men, are football players experiencing early aging and living with illness and disability for more years than their non-football peers?

MedicalResearch.com Interview with: Rebecca Arden Harris, MD, MSc Assistant Professor of Family Medicine and Community Health at the Hospital of the University of Pennsylvania Senior Fellow, Leonard Davis Institute of Health Economics Perelman School of Medicine, University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: The impact of the nationwide overdose epidemic on Black women has received little attention from policy-makers, researchers, or the press. MedicalResearch.com: What are the main findings? Response:  Over the 7-year study period, preventable overdose deaths among Black women resulted in nearly 0.75 million years of life lost (YLL). Women aged 25-34 have suffered a rising proportion of this burden. (more…)
Author Interviews, Mental Health Research / 28.11.2022

Sound healing is an alternative therapy that uses sound waves to heal the mind and body. This therapy is based on the belief that all matter is vibrating at a certain frequency and that disease or ill health occurs when the body’s natural frequency is out of alignment. Sound healing practitioners use a variety of tools, including singing bowls, gongs, and tuning forks, to restore the body’s natural frequency. There are many benefits of sound healing, including reducing stress, promoting relaxation, improving sleep, and reducing pain. Sound healing can also be used to treat a wide range of conditions, such as anxiety, depression, PTSD, and addiction. If you are looking for a non-invasive way to improve your health and well-being, sound healing may be right for you. (more…)
Alzheimer's - Dementia, Author Interviews, Nutrition / 26.11.2022

MedicalResearch.com Interview with: Thomas M Holland, MD, MS Assistant Professor Rush Institute for Health Aging Rush College of Medicine & Rush College of Health Sciences https://www.rushu.rush.edu/faculty/thomas-m-holland-md-ms MedicalResearch.com: What is the background for this study? Response: My late mentor Martha Clare Morris, ScD had published a manuscript investigating leafy green intake, and the nutrients found therein, and cognition. I wanted to take this thought a step further and investigate the potential association bioactives, found in vegetables, like leafy greens, has to cognition. Further, this is a continuation of the research I published in the green journal in 2020 associating flavonols to incident Alzheimer’s dementia. This study extends the understanding that flavonols are not only beneficial for the most detrimental outcome of Alzheimer’s dementia (in decreasing the risk), but also advantageous in mitigating components of the, clinical syndrome i.e. decreasing the rate of cognitive decline.

Alzheimer's - Dementia, Author Interviews, Nutrition / 14.11.2022

MedicalResearch.com Interview with: Alessandro Palmioli PhD Cristina Airoldi PhD Department of Biotechnology and Biosciences, University of Milano-Bicocca, NeuroMI, Center for Neuroscience, University of Milano-Bicocca MedicalResearch.com: What is the background for this study? beer-hopsResponse: We started many years ago by studying some natural and synthetic molecules that were able to counteract the early stages of this disease. With a view to early prevention, we wondered if these molecules could be routinely taken with the diet or dietary supplements. So our studies focused on the search for bioactive molecules present in food and edible plants. Hops are very rich in polyphenolic compounds, and for this reason it is historically used for the production of beer, but also for the preparation of herbal teas and infusions, and its uses in traditional medicine are known. In recent years we have also collected interesting results on Coffee, Sage, Radix Imperatoriae, Cocoa and Cinnamon extracts. (more…)
Mental Health Research, Nursing / 03.11.2022

When thinking about looking after your health, you might not consider your mental health alongside that. It’s just as important, though, as it can affect every area of your life, from your work life to how much rest you get at night. It’s especially important for healthcare professionals to consider how they are doing mentally. That’s because, with such a mentally demanding role, it is all too easy for them to let their mental health slide without realicing it. Unfortunately, that can lead to far more than a slightly stressful workday. Providing access to resources such as a nurses hotline can offer essential support and guidance for those in the healthcare profession, helping them manage their mental well-being effectively. If you’re a healthcare worker, here is why it’s so important to look after your mental well-being. To Show Up to Every Shift healthcare-nursing-burnout Good mental health means you are more likely to take control of your day. Whether you have an early shift or a long one, with a more positive mindset, you are sure to show up and get the work done to the best of your ability. It also means that those that choose their shifts (such as locum pharmacists, GPs, or nurses) will take on more work because they feel like they can manage it. So if you’re a locum healthcare worker, even using a shift-scheduling platform such as Workflare can help you gain more control over your day and, in turn, feel less stressed. (more…)

There is a critical need to address the mental health of children and adolescents in primary care so that they can get the support they need to thrive. (more…)
Author Interviews, Brigham & Women's - Harvard, Schizophrenia, Sleep Disorders / 18.10.2022

MedicalResearch.com Interview with: Michael J. Prerau, Ph.D. Assistant Professor of Medicine, Faculty, Division of Sleep Medicine Harvard Medical School Associate Neuroscientist and Director of the Neurophysiological Signal Processing Core Division of Sleep and Circadian Disorders Department of Medicine Brigham and Women's Hospital MedicalResearch.com: What is the background for this study? Response: The brain is highly active during sleep, which makes it an important, natural way to study neurological health and disease. Scientists typically study brain activity during sleep using the electroencephalogram, or EEG, which measures brainwaves at the scalp. Starting in the mid 1930s, the sleep EEG was first studied by looking at the traces of brainwaves drawn on a paper tape by a machine. Many important features of sleep are still based on what people almost a century ago could most easily observe in the complex waveform traces. Even the latest machine learning and signal processing algorithms for detecting sleep waveforms are judged against their ability to recreate human observation. In this study, the researchers asked: What can we learn if we expand our notion of sleep brainwaves beyond what was historically easy to identify by eye? (more…)
Alzheimer's - Dementia, Author Interviews, Infections, Parkinson's / 22.09.2022

MedicalResearch.com Interview with: Jiangwei Sun PhD Postdoctoral researcher in Prof. Jonas Ludvigsson's group Department of Medical Epidemiology and Biostatistics Karolinska Institutet MedicalResearch.com: What is the background for this study? Response: A potential infectious etiology has been hypothesized for neurodegenerative diseases, as findings in animal studies have demonstrated that infectious processes might impact pathogenesis, phenotype, and progression of neurodegenerative disease. The extrapolation of such findings to a human context is however not straightforward. previous studies have mostly examined the role of specific pathogens on a specific neurodegenerative disease, e.g., herpesvirus for Alzheimer’s disease, and influenza, hepatitis C virus, and Helicobacter pylori for PD, with inconclusive results. Although several studies have also assessed associations between infectious diseases and risk of dementia and AD, influence of potential surveillance bias (greater-than-expected surveillance of disease after infections) and reverse causation (due to for example diagnostic delay of neurodegenerative diseases) on the associations was not always fully addressed. Therefore, whether infection is indeed a risk factor rather a comorbidity or secondary event of neurodegenerative disease remains unknown. In contrast to Alzheimer’s disease, and Parkinson’s disease, the potential link between infection and ALS has been less explored. (more…)

MedicalResearch.com Interview with: Clare Jensen O’Haire Research Team Center for the Human-Animal Bond Purdue University College of Veterinary Medicine MedicalResearch.com:  What is the background for this study?  Response: Service dogs for PTSD are becoming more common and the evidence shows they can help improve mental health and quality of life for many veterans with PTSD. However, some veterans benefit more than others. Our research goal was to ask for the very first time: Why? (more…)
Author Interviews, Brain Injury, NEJM / 09.06.2022

MedicalResearch.com Interview with: Daniel Perl MD Uniformed Services University of the Health Sciences Professor of Pathology at USUHS and Director of the CNRM's Brain Tissue Repository Uniformed Services University of the Health Sciences Bethesda, Maryland MedicalResearch.com:  What is the background for this study?  Response: Chronic traumatic encephalopathy (CTE) is a brain disorder that is predominantly seen in individuals who have suffered from repeated impact head trauma, such as occurs in former boxers or American football players.  CTE has very specific alterations in the brain and can only be diagnosed at autopsy.  Some have claimed that, in addition to former contact sport participants, individuals who served in the military and were repeatedly exposed to blast (explosions) are also at increased risk for developing CTE.  However, this claim has been based on a rather small number of anecdotal cases.  The DoD/USU Brain Tissue Repository is the only facility in the world that is exclusively dedicated to the collection and study of donated brain specimens derived from deceased active duty and retired service members.  We used the resources of this facility to examine 225 consecutively collected brain specimens for the presence of CTE.  This would to provide a view of how common CTE was in this setting and, when diagnosed, was the disease correlated with prior blast exposure, participation in contact sports and other forms of head trauma, and with certain forms of symptomatology such as development of PTSD, alcohol/substance abuse, death by suicide, etc. (more…)
Author Interviews, COVID -19 Coronavirus, Mental Health Research, Rheumatology / 07.06.2022

MedicalResearch.com Interview with: Kelly Gavigan, MPH Director, Data Management and Analytics Global Healthy Living Foundation MedicalResearch.com:  What is the background for this study?  Response: COVID-19 is of particular concern for people living with autoimmune and rheumatic disease, not only because they have an increased risk of infection but also because of the heightened sense of isolation due to strict social distancing protocols that many patients continue to follow through today. As a result, we wanted to better understand if symptoms among the autoimmune and rheumatic disease patients in our ArthritisPower research registry were impacted throughout the COVID-19 pandemic. We previously conducted and reported on an analysis of patient reported outcome data from the ArthritisPower registry between the months of January 2020 to April 2021 at the American College of Rheumatology Convergence in 2021. We conducted a follow-up analysis between May and December 2021, which is our area of focus in this particular abstract. (more…)
Author Interviews, Brigham & Women's - Harvard, Cognitive Issues, Exercise - Fitness / 23.04.2022

MedicalResearch.com Interview with: Robert A. Stern, Ph.D. Professor of Neurology, Neurosurgery, and Anatomy & Neurobiology Director of Clinical Research, BU CTE Center Senior Investigator, BU Alzheimer’s Disease Research Center Boston University School of Medicine MedicalResearch.com:  What is the background for this study?  Response: The link between playing American football at the professional level and later-life brain disorders like chronic traumatic encephalopathy – or CTE -- and ALS has received increasing attention over the past 15 years. Previous research has shown that former NFL players are more likely to die from CTE and amyotrophic lateral sclerosis (ALS) and more likely to report cognitive impairment, behavioral changes, and dementia during life. Despite previous research focusing on the later-life effects of playing American football at the professional level, the long-term effects of college football participation remain largely unknown. We had two goals for this new investigation. The first was to conduct a survey of the current overall health status, including cognitive and other neurological disorders, of older former college American football players compared with men in the general population. The second goal was to examine the mortality rate and causes of death in a cohort of older former college football players. The target population for this study was all 447 former Notre Dame football players who were listed as seniors on the varsity rosters during the 1964-1980 seasons. This was the era of legendary coaches Ara Parseghian and Dan Devine. I should add that this study was fully independent of the University of Notre Dame. (more…)
Alzheimer's - Dementia, Author Interviews, Race/Ethnic Diversity, UCSF / 20.04.2022

MedicalResearch.com Interview with: Erica Kornblith, PhD Assistant Professor, Psychiatry UCSF Weill Institute for Neurosciences MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: As the population of the United States grows more diverse and dementia is a serious public health concern, we hoped to understand whether differences in dementia risk exist based on race or ethnicity.  Older studies have shown that Black and Hispanic folks have higher risk of dementia, perhaps due to medical risk factors, diagnostic bias, lack of equal access to health care and education, or the health effects of racism, among other factors.  However, these older studies have been small or limited geographically or by only studying a few race and ethnicity groups. 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. (more…)
Aging, Alzheimer's - Dementia, Author Interviews, Brigham & Women's - Harvard, Genetic Research, Nature / 20.04.2022

MedicalResearch.com Interview with: Michael B. Miller, MD, PhD Instructor, Harvard Medical School Department of Pathology Brigham and Women's Hospital MedicalResearch.com:  What is the background for this study? Would you explain what is meant by somatic genetic changes and how they might occur?  Response: Changes, also called mutations, in the DNA sequence of genes can be passed from parents to their children, and explain why many diseases run in families. This kind of DNA change is called a germline mutation and is present in every cell in a person’s body. Gene mutations can also occur in a subset of cells of a person, in which case they are called somatic mutations. Somatic mutations are well known as a cause of cancer, and recent research has found that somatic mutations can also happen in non-cancerous cells that appear otherwise normal. Recent studies have even found that somatic mutations are present in neurons, cells in the brain that transmit electrical signals and play an important role in how the brain functions. Furthermore, in neurons, somatic mutations increase with age, so we set out to understand if somatic mutations might be playing a role in age-related brain diseases like Alzheimer’s. (more…)
Author Interviews, JAMA, Mental Health Research, Pediatrics, Social Issues / 13.04.2022

MedicalResearch.com Interview with: Regina Triplett, M.D., M.S. Developmental Neuroscience Post-Doctoral Research Scholar Department of Neurology Washington University in St. Louis, MO  MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: This is an ongoing, longitudinal, prospective study of 399 pairs of mothers studied throughout pregnancy and their infants, designed to investigate exposure to early life adversity (prenatal poverty and stress) on infant brain development and behavior in early childhood. We examined measures of maternal socioeconomic status including neighborhood factors and stress/mental health during pregnancy in relation to data from infant brain MRI scans conducted in the first weeks after birth. We found that poverty during pregnancy is associated with reduced size and folding of infant brains. We found these associations across the whole brain and not specific to one region. (more…)
Author Interviews, Blood Pressure - Hypertension, Cognitive Issues / 05.04.2022

MedicalResearch.com Interview with: Dr. Yangfeng Wu Peking University Clinical Research Institute Peking University MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: It is well-established that elevated blood pressure (BP) at single time point can contribute to increased risks of suffering accelerated cognitive decline, dementia, and mortality. Nevertheless, BP levels could experience significant alterations as time goes, indicating the necessity of monitoring BP longitudinally. In other words, using blood pressure levels measured at baseline to predict future outcomes in a longitudinal cohort with a long-term follow-up period ≥20 years, becomes controversial. Cumulative BP levels have been indicated as a feasible approach for evaluating long-term exposure of BP levels, which might have the ability to respond to this controversy. This is the main reason why we performed this research to evaluate the predictive values of cumulative BP levels, especially additional values beyond baseline blood pressure levels, for future neurocognitive and longevity outcomes.

Author Interviews, Autism, Medical Imaging / 02.04.2022

MedicalResearch.com Interview with: Alpen ORTUĞ, PhD Postdoctoral Research FellowMassachusetts General Hospital Department of Radiology Martinos Center for Biomedical Imaging Boston, MA   MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Finding the earliest diagnosis possible for autism spectrum disorder (ASD) is one of the main goals for researchers studying ASD. This study aimed to investigate the critical abnormalities in prenatal brain development in ASD using structural magnetic resonance imaging (MRI). We hypothesized that volumetric analyses of brain segmentations are useful to identify such abnormalities before birth. We have retrospectively analyzed fetal MRI based on the knowledge that the same individuals were later diagnosed with autism spectrum disorder. We have evaluated developmental abnormalities in brain structures of prospective ASD fetuses using volumetric segmentation. The current study is still preliminary, but the ‘insula’ of the brain showed statistically significant volumetric enlargement in prospective ASD patients, compared to the other three control groups.  (more…)
