A Message from Dr. McMillan

Diseases rarely appear out of nowhere; more often, they represent a slow accumulation of biological damage that only becomes visible once the body’s reserve is exhausted.

Microclotting may be one of these hidden post-COVID processes - an abnormality affecting blood flow, oxygen delivery, and vascular repair that deserves far more urgent investigation across the population.

If we ignore it now because the acute phase of the pandemic is over, we may later discover that some of the long-term damage was preventable, but no longer reversible.

COVID-19

  • Spike protein fragments may inflame and kill capillaries, a process called capillary rarefaction, reducing microcirculation.

  • Microscopic clotting, stiffened blood cells, and closing precapillary sphincters restrict blood flow through tiny vessels.

  • Routine blood panels and cardiac imaging read normal, so symptoms get dismissed as anxiety or aging.

  • Venous oxygen saturation can plunge from about 70 percent to 11 to 15 percent in severe cases.

Why this is important: Some patients feel progressively unwell yet pass every standard test. This perspective argues that lingering spike protein injures capillaries and chokes blood flow long before conventional panels detect anything, suggesting early anticoagulant, antihistamine, or apheresis intervention could prevent silent, accumulating microvascular damage.

HEALTH

  • Nervous system dysfunction may drive Long COVID dizziness, exercise intolerance, and other autonomic symptoms in some patients.

  • The brain is a physical organ regulating heart rate, breathing, digestion, and pain processing.

  • A program called Second Arrow teaches how brain factors contribute, reducing fear around the condition.

  • Education is not a cure and must not replace medical care, pacing, or specialist treatment.

Why this is important: Dismissing Long COVID as psychological harms patients and ignores biology. Researchers show that teaching people how the nervous system shapes symptoms can lessen fear and restore hope, while stressing this complements, never replaces, medical investigation, pacing, and specialist care.

NEWS HIGHLIGHTS

🚥 Long Uninterrupted Sitting Is Linked to Higher Cancer Death Risk, but Frequent Movement Breaks Appear Protective: Total sitting time may matter less than how it is broken up. Analyzing UK Biobank data, researchers found that long unbroken sedentary stretches track with greater cancer mortality, hinting that brief, frequent movement could lower risk with almost no effort or cost.

🚥 A Lower-Inflammatory, Healthy Diet May Reduce Dementia Risk Even in People Carrying Biological Risk Markers: Genetic and biological risk need not seal a person's cognitive fate. Following Swedish adults for fifteen years, researchers found anti-inflammatory eating linked to meaningfully lower dementia risk, especially among those already showing warning biomarkers, though the observational design shows correlation rather than proof.

🚥 A New Hypertrophic Cardiomyopathy Mechanism Shows Mavacamten Works Across Different Disease-Causing Mutation Types: Not every genetic heart disease responds to the same drug, so mechanism matters. Researchers showed one common mutation sabotages a key contractile protein's interactions, and that mavacamten, the only targeted therapy, still works across mutation types, widening who might safely benefit from it.

🚥Engineered Bacteriophages Disarm Crohn's-Linked E. Coli, Easing Gut Inflammation Without Wiping Out Healthy Bacteria: Broad antibiotics wreck the gut ecosystem they aim to heal. This McMaster work shows precision phages can defang the specific bacteria fueling Crohn's inflammation while leaving helpful microbes intact, and even make steroids work at lower doses, pointing toward gentler inflammatory bowel disease treatment. Human trials come next. [SOURCE]

🚥 Genome-Edited Stem Cells Hide From Antibodies, Opening a Path to Chemotherapy-Free Bone Marrow Transplants: Bone marrow transplants usually demand toxic chemotherapy to clear space, barring fragile patients. Boston researchers edited donor stem cells to evade the antibodies used for that clearing, letting healthy cells engraft without chemo and hinting at safer therapies for blood disorders and cancer immunotherapy alike.

🚥 Most Obesity Drugs Drive Weight Loss but Rarely Improve Quality of Life or Heart Outcomes Within a Year: Calling cystic fibrosis a lung disease misses where it often starts and where new dangers lie. Ooi shows the gut is central, with digestive symptoms in every patient and growing colorectal cancer risk as people live longer. Understanding this shifts screening and care toward the whole body, not only breathing. [SOURCE]
