The Winding Path Towards an Inverse Relationship Between Sun Exposure and All-cause Mortality

May 10, 2026
| No Comments
| Cancer, Cardiovascular Health, Miscellaneous, Ultraviolet - Sun Exposure

Comment: I always prioritize all-cause mortality data over mechanism, and the hypothesis that sun exposure is negative is at this point dogmatic. This 2018 review is another showing the prevailing clinical mandate for UV avoidance conflicts with the documented reality that sun avoidance is a negative factor for human longevity. The Melanoma in Southern Sweden […]

The effect of aged garlic extract on the atherosclerotic process – a randomized double-blind placebo-controlled trial

May 7, 2026
| No Comments
| Cardiovascular Health, Nutritional Supplements

Comment: I use Aged Garlic Extract in my practice for plaques and calcifications as there are no risks to offset the potential benefit. But I do need to apply the same standards to the study as I do to a statin trial. This data reveals presents a conflicting baseline that muddies any clear clinical conclusion. […]

Hormone Replacement Therapy and Cardiovascular Outcomes by Race and Ethnicity: MESA (Multi-Ethnic Study of Atherosclerosis)

March 24, 2026
| No Comments
| Cardiovascular Health

Comment: This observational MESA study highlights the stark conflict between the idea that early HRT initiation saves lives and the more likely textbook manifestation of healthy user bias impacting outcomes of medical efficacy. Unfortunately the study does not have the data on the formulation used (oral, topical, vaginal), however given the time of intake (2000-2002), […]

High-sensitivity C-reactive protein: potential adjunct for global risk assessment in the primary prevention of cardiovascular disease

February 28, 2026
| No Comments
| Cardiovascular Health, Labs & Statistics

Comment: I incorporate high-sensitivity CRP into every cardiovascular workup because it captures a physiological reality that standard lipid panels miss. As this foundational paper details, hsCRP identifies high-risk individuals—even those with low cholesterol—who are otherwise invisible to standard screening algorithms.  It is an unfortunate reality that markers are frequently ignored because there is no FDA-approved […]

Postmenopausal Hormone Therapy and Risk of Stroke: Impact of the Route of Estrogen Administration and Type of Progestogen

February 9, 2026
| No Comments
| Cardiovascular Health, Medications - General Pharmaceuticals, Miscellaneous

Comment: There is an assumption that specific routes of hormone therapy (MHT) offer a safe harbor from cardiovascular risk, yet this systematic review of over 5.5 million women identifies a profound disconnect between biochemical promise and systemic biological reality. While early initiation is frequently justified by observational data, we should recognize that these perceived benefits […]

The route of administration, timing, duration and dose of postmenopausal hormone therapy and cardiovascular outcomes in women: a systematic review

February 8, 2026
| No Comments
| Cardiovascular Health, Medications - General Pharmaceuticals

Comment: This systematic review of 33 studies and over 2.5 million women reveals a critical tension between biochemical plausibility and actual clinical outcomes, at least for oral dosing. While observational data suggests early initiation reduces coronary heart disease, we should recognize that some of these findings are likely compromised by Healthy User Bias—where healthier women […]

Antimicrobial Natural Product Berberine Is Efficacious for the Treatment of Atrial Fibrillation

January 31, 2026
| No Comments
| Cardiovascular Health, Nutritional Supplements

Comment: This comparison of 88 completed follow-ups shows that natural alkaloids can function as antiarrhythmics. While amiodarone converts rhythm significantly faster (211 vs. 356 minutes), it does so while maintaining a “brittle” rhythm that is more prone to attrition over time than the rhythm supported by berberine. The statistical parity between the two agents at […]

Coffee consumption and adverse cardiovascular events in patients with atrial fibrillation

January 31, 2026
| No Comments
| Cardiovascular Health, Diet & Nutrition

Comment: We have reached a saturation point in the evidence regarding coffee and cardiovascular health. Despite persistent concerns that coffee triggers AF episodes, this analysis of 3,835 patients confirms that these subjective fears do not translate into hard clinical harm. The physiological divergence is stark: while patients worry about palpitations, the data reveals a 23% […]

Effective management of atherosclerosis progress and hyperlipidemia with nattokinase: A clinical study with 1,062 participants

January 29, 2026
| No Comments
| Cardiovascular Health, Nutritional Supplements

Comment: This study shifted my thinking around nattokinase as it somewhat clarified contradictions in the literature around efficacy, specifically it showed the failure of the “standard” 2,000 FU recommendation to hit the physiological threshold necessary for vascular remodeling. This study of 1,062 participants suggests that biology requires far more significant saturation to move the needle […]

Association of eating duration less than 8 h with all-cause, cardiovascular, and cancer mortality

January 26, 2026
| No Comments
| Cancer, Cardiovascular Health, Diet & Nutrition

Comment:   We are currently witnessing a significant conflict between the “biohacking” narrative—which promotes ultra-short eating windows (<8 hours) for longevity and metabolic optimization—and the hard clinical endpoints presented in this large-scale observational study. While the biochemical mechanisms of Time-Restricted Eating (TRE) are plausible in animal models, the hierarchy of evidence demands that we prioritize […]
