MedicalResearch.com Interview with: [caption id="attachment_72018" align="alignleft" width="200"]Andrey Vyshedskiy, Ph.D.Neuroscientist from Boston University Dr. Vyshedskiy[/caption] Andrey Vyshedskiy, Ph.D. Neuroscientist from Boston University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Certain conditions, such as autism and Down syndrome, can limit a child’s ability to develop full language comprehension. In these cases, children often become “stuck” at a specific, quantized level of understanding:
  • Command Phenotype: Individuals at this level understand single words and simple commands but have difficulty combining nouns with adjectives or interpreting more complex instructions.
  • Modifier Phenotype: Individuals at this level can comprehend combinations of nouns and adjectives—for example, they can identify a small yellow pencil among pencils, straws, and Lego pieces of varying sizes and colors. However, they struggle with more complex language structures, such as sentences containing spatial prepositions, possessive pronouns, verb tenses, and narratives like fairy tales.
  • Syntactic Phenotype: Most children naturally progress to this most-advanced level of comprehension, characterized by the ability to understand full syntactic structures and more sophisticated language forms.
While the Command and Syntactic Phenotypes were anticipated by linguistics and developmental psychology, the distinct Modifier Phenotype was unexpected. Across several studies involving nearly 100,000 participants, these three phenotypes consistently emerged. Together with a recent longitudinal study of language development in over 15,000 participants, these findings highlight the critical importance of early engagement in syntactic conversations for the acquisition of the Syntactic Phenotype.

MedicalResearch.com Interview with: [caption id="attachment_59428" align="alignleft" width="150"]Ashish Verma, MD Assistant Professor, Nephrology Department of Medicine Boston University Dr. Verma[/caption] Ashish Verma, MD Assistant Professor, Nephrology Department of Medicine Boston University MedicalResearch.com: What is the background for this study? Would you tell us a little about aldosterone? Response: “Recent randomized, controlled trials have shown that a drug called finerenone is effective in delaying CKD progression and adverse cardiovascular outcomes in patients with chronic kidney disease and diabetes. However, the role of aldosterone in this process was not directly investigated and levels of the hormone were not measured,” “Since excessive levels of aldosterone is common, yet mostly unrecognized, we hypothesized that one reason why finerenone was effective in lowering the risk of CKD progression was that it was treating unrecognized high concentrations of the hormone.” To study this we investigated the associations between aldosterone concentrations in the blood and kidney disease progression among 3680 participants in the Chronic Renal Insufficiency Cohort study, which ran in seven clinics in the US between 2003 and 2008. The participants were aged between 21 and 74 years old. Aldosterone is a steroid hormone secreted by the adrenal glands, which sit above the kidneys. Its main role is to regulate salt and water in the body, and so it plays a central role in controlling blood pressure. Too much of it can lead to high blood pressure, cardiovascular and kidney diseases.

MedicalResearch.com Interview with: [caption id="attachment_59068" align="alignleft" width="133"]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 Dr. Stern[/caption] 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.
