June 08, 202639 - Instant insights: How to screen for primary aldosteronism (updated guidelines) (9 min)
In this special episode of Healthier World designed to give you Instant Insights, we take a look at primary aldosteronism (PA)- an often underdiagnosed, yet prevalent cause of hypertension. In this episode, we challenge traditional screening methods and introduce a streamlined diagnostic approach. By recognizing the signs of Primary Aldosteronism earlier, providers can improve patient outcomes and avoid increased risk for cardiovascular and metabolic conditions associated with untreated PA.
This episode will
Explain the mechanisms underlying PA and how they disrupt the normal renin-aldosterone feedback system (1:50)
Highlight the limitations of historic methodology, and describe updated guidance on PA evaluation (3:10)
Walk through an example comparing the ARR with the suppressed renin approach for assessing PA (5:50)
Explain the cardiometabolic consequences of untreated PA and the importance of proactive screening, particularly in patients with chronic kidney disease (6:50)

May 26, 202638 - Instant insights: Using ANAlyzeR to navigate systemic autoimmune disease (6 min)
Millions of people with systemic autoimmune diseases face a long and frustrating journey to diagnosis, often lasting years. In this episode, Dr Maeson Latsko explores how to expand on the standard antinuclear antibody (ANA) test for autoimmune disease. While the ANA test is a critical starting point, a negative result doesn't rule out disease, and a positive result is not a definitive diagnosis. The ANAlyzeR™ panel is a comprehensive test that evaluates 25 autoimmune markers from a single blood draw. This approach provides a full-picture view from the outset, helping clinicians differentiate between 8 common autoimmune conditions, reduce diagnostic uncertainty, and get patients on the path to treatment sooner.
Learning Objectives
This episode will:
Describe the challenges and delays in the typical diagnostic journey for patients with systemic autoimmune diseases (1:00)
Explain the role of the ANA test as a first-line screening tool (2:00)
Introduce the ANAlyzeR™ comprehensive panel as a solution to shorten the diagnostic process by simultaneously evaluating 25 analytes, to identify 8 common autoimmune conditions, regardless of the initial ANA result (3:55)

May 04, 202636 - Instant insights: Identifying and diagnosing celiac disease (8 min)
More than 80% of patients with celiac disease remain undiagnosed or misdiagnosed. In this episode, Maeson Latsko, PhD, explores the reasons for the diagnostic odyssey in celiac disease, from the disease’s wide range of symptoms to common pitfalls in testing. Celiac disease triggers a specific autoimmune response where the body attacks its own small intestines after gluten exposure, leading to malabsorption and comorbid conditions. Providers can screen for celiac disease using a serologic panel that detects key autoantibodies like tTG-IgA and accounts for IgA deficiency.
This episode will
Describe the autoimmune mechanism in celiac disease, including the role of tissue transglutaminase (tTG) and the HLA-DQ2/DQ8 genetic predisposition (2:00)
Identify the key serologic markers used for diagnosis, including tTG-IgA, endomysial antibody (EMA), and the purpose of IgG-based backup tests for patients with IgA deficiency (2:40)
Outline the clinical pathway for diagnosis, from initial testing with an automated reflex panel to the role of gut biopsy and follow-up monitoring (5:10)

April 13, 202635 - Instant insights: Hypercortisolism in difficult-to-control type 2 diabetes (8 min)
More than 36 million Americans are living with type 2 diabetes, and an estimated 30%-50% of patients remain uncontrolled. In this episode, Maeson Latsko, PhD, explores an under-recognized contributor to difficult-to-control diabetes: hypercortisolism. Hypercortisolism disrupts glucose metabolism and insulin function, leading to elevated HbA1c that isn’t as responsive to traditional treatment. Providers can screen for hypercortisolism using an overnight dexamethasone suppression test.
This episode will
Review the clinical characteristics of difficult-to-control diabetes and when hypercortisolism should be considered (1:00)
Explain how hypercortisolism contributes to type 2 diabetes (2:25)

March 02, 202632 - 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)
