Shingles vaccine reduces risk of heart disease by 23%, study of one million
a year ago
- Shingles vaccine may lower the risk of heart disease and stroke, according to a new South Korean study.
- The study analyzed over 1 million people aged 50 and older, finding a 23% lower risk of cardiovascular disease in vaccinated individuals.
- Reduced risk was most noticeable up to eight years post-vaccination, especially in males, those under 60, and individuals with unhealthy lifestyles.
- Shingles can cause inflammation in blood vessels and nerve damage, potentially leading to heart disease and irregular heart rhythms.
- The vaccine may be more effective in younger patients and males due to stronger immune systems.
- The study used an older vaccine variation (live zoster vaccine), which is being phased out in favor of the more effective Shingrix vaccine.
- Limitations include potential differences in health behaviors between vaccinated and unvaccinated groups and lack of diversity in study populations.
- Other studies suggest shingles vaccination may also reduce dementia risk by 20%, possibly due to reduced inflammation in brain tissue.
- Future research should focus on randomized clinical trials and more diverse populations to confirm these findings.
When graphic design saves lives
a year ago
- Graphic design plays a crucial role in public health communication, especially during crises like the HIV/AIDS epidemic.
- Harvard Library has digitized over 3,000 AIDS-related posters from around the world (1990-2004), showcasing effective messaging strategies.
- Effective posters combine a simple message with an emotional appeal to improve retention and understanding.
- Public health messaging has evolved from one-size-fits-all campaigns to audience-specific, co-created content.
- Positive, affirming messages are more effective than shame-based approaches in changing behavior.
- Modern HIV prevention (e.g., PrEP, antivirals) has outdated some historical poster information, but the collection serves as a memorial and learning tool.
- Despite advancements, HIV transmission persists, highlighting the need for continued education and updated messaging (e.g., 'U=U').

Mr. Secretary, Reclassify the Statin
a year ago
- Reclassifying low-dose statins from prescription-only to over-the-counter (OTC) could significantly improve cardiovascular prevention in the U.S.
- Scientific evidence shows that lowering LDL cholesterol reduces the risk of myocardial infarction or stroke by approximately 22% per mmol/L reduction.
- Statins have a strong safety profile, with serious side effects like muscle injury and hepatotoxicity being extremely rare (<0.1%).
- The UK has already made simvastatin 10 mg available OTC since 2004 without safety concerns, setting a precedent.
- FDA rejections for OTC statins have focused on consumer competence rather than safety, despite technological solutions like web-apps showing high concordance between consumer and clinician judgment.
- Even modest uptake (e.g., 1% of eligible adults) could prevent ~14,000 heart attacks and strokes, saving ~56,000 quality-adjusted life-years at minimal cost.
- Statins like lovastatin are derived from natural sources (e.g., red-yeast-rice mold), making them comparable to supplements already available.
- Proposal includes a phased approach: initial pharmacist-screened sales followed by full OTC availability after post-market data confirms safety.
- Removing this regulatory barrier could provide a measurable public health win without new technology or significant funding.
