    32 - Instant insights: Blood-based biomarkers for Alzheimer’s Disease (8 min)

    Approximately 55 million people have dementia. Alzheimer’s disease (AD) is the most common form of dementia, impacting nearly 7 million Americans. Blood-based biomarkers such as the beta amyloid 42/40 ratio and phosphorylated tau (p-tau217) are now providing earlier and more accessible insights into Alzheimer's pathology. These markers help differentiate Alzheimer's from other dementias, support early intervention, and improve diagnostic confidence. The Quest Diagnostics panel combines these biomarkers to generate a highly accurate likelihood score for Alzheimer's pathology, enhancing clinical decision-making and care planning. This episode will Describe the pathology of AD (2:00) Summarize the role of blood-based biomarkers in the evaluation of suspected AD (3:00) Explain how biomarkers can support patient evaluation and help clinical decision-making (6:30) To learn more, please review the additional resources below for information on our cardiovascular, metabolic, endocrine, and wellness offerings as well as educational resources and insights from our team of experts.

    30 - Instant insights: hs-CRP in cardiovascular risk (7 min)

    In this special episode of Healthier World designed to give you Instant Insights, Dr Maeson Latsko discusses the critical role of inflammation in cardiovascular events, focusing on the importance of high-sensitivity C-reactive protein (hsCRP) levels. Cardiovascular events often stem from the rupture of soft plaque, which is fueled by inflammation. Hs-CRP can be used to gauge cardiovascular risk, above even when LDL-C is considered normal. Hs-CRP should be thought of as a red flag for chronic conditions that increase risk for CVD, such as metabolic syndrome, diabetes, and hypertension, emphasizing the importance of addressing inflammation to prevent heart attacks and strokes. This episode will Differentiate hs-CRP from general CRP levels in the context of acute and chronic inflammation (1:10) Introduce hs-CRP as a critical biomarker for assessing cardiovascular risk (1:50) Highlight the integration of hs-CRP into cardiovascular prevention guidelines (5:00) To learn more, please review the additional resources below for information on our cardiovascular, metabolic, endocrine, and wellness offerings as well as educational resources and insights from our team of experts.

    27 - Viral infections and cardiometabolic complications (12 min)

    Most people recognize that acute inflammation occurs when a person experiences a viral illness. However, many people are unaware that this inflammatory response can increase risk for cardiometabolic events. In this episode, Dr Marc Penn and Maeson Latsko, PhD, discuss how viral infections such as influenza and SARS-CoV-2 trigger inflammation, which can destabilize plaque, accelerate atherosclerosis, and increase the likelihood of cardiovascular events. A cardiometabolic risk assessment is an essential tool to reduce cardiovascular events linked to viral illnesses. This episode will Explain how acute and chronic viral illness increase cardiovascular risk and how vaccinations and infection prevention strategies are key for lowering viral-related cardiovascular complications (1:00) Highlight how metabolic dysfunction such as insulin resistance, dyslipidemia, obesity, and MASLD amplifies the cardiovascular impact of viral infections (7:00) Demonstrate how noninvasive screening tools such as the FIB-4, hs-CRP, and ApoB help identify high-risk patients (9:00) To learn more, please review the additional resources below for information on our cardiovascular, metabolic, endocrine, and wellness offerings as well as educational resources and insights from our team of experts.

    26 - Type 1 Diabetes: From autoimmune origin to cardiometabolic consequences (15 min)

    Type 1 Diabetes (T1D) is an autoimmune disease that remains underrecognized, especially in adults. Once thought of as a childhood condition, nearly half of new cases are now diagnosed in adulthood. T1D can lead to serious complications, including diabetic ketoacidosis, severe hypoglycemia, and eventually cardiometabolic disease. In today’s episode, Maeson Latsko, PhD and Franklin Warren discuss the T1D screening recommendation by the American diabetes Association and how this guidance gives physicians the opportunity to provide more timely, effective interventions, increasing the possibility of preventing complications. This episode will Outline what T1D is and the prevalence of T1D in both children and adults (2:00) Recognize the risk and complications associated with delayed or missed diagnosis, including diabetic ketoacidosis and long-term organ damage (6:20) Review the latest ADA recommendations for screening and early detection of T1D (8:00) To learn more, please review the additional resources below for information on our cardiovascular, metabolic, endocrine, and wellness offerings as well as educational resources and insights from our team of experts.
