すごい論文出た。
HPVワクチンを義務化したバージニア州では若者の子宮頸がんは減少せず逆に増加していた、と。
若者の子宮頸がんをゼロにした!というイギリスの論文とは対照的ですね。ま、若者の子宮頸がんは少ないから、ブレが大きいのかな。
少なくとも学会はイギリスの方だけ取り上げるのはやめるべきでしょう。こういう事例もあるのは事実なのだから。

A massive new study just linked the popular sugar substitute xylitol to a 57% higher risk of stroke and heart attack.
A large-scale observational study presented at the European Society of Cardiology (ESC) Congress has revealed a concerning connection between the common sugar substitute xylitol and cardiovascular risks.
Xylitol, a sugar alcohol widely added to low-calorie foods like chewing gum, jams, yogurts, and oral care products, is often used in concentrations up to 1,000 times higher than its natural occurrence. Researchers tracking 17,710 participants found that those with the highest blood levels of the sweetener faced a 57% higher risk of suffering a heart attack, stroke, or dying within six years compared to those with the lowest levels.
Even over a 30-year span, the elevated risk persisted at 18%, suggesting a strong, dose-dependent relationship between high xylitol levels and cardiovascular events.
Although the study is observational and cannot definitively prove that xylitol causes cardiovascular events, researchers point out that previous laboratory tests show the sweetener can increase platelet activity and promote blood clotting. Experts emphasize that many consumers turn to artificial sweeteners under the assumption that they are a universally healthier alternative to sugar. However, this growing body of research highlights the urgent need to reevaluate the long-term safety of sugar alcohols. While there is no immediate reason to throw out toothpaste containing trace amounts of xylitol, health professionals suggest focusing on a balanced diet with reduced processed foods as the medical community works to understand the full cardiovascular implications of high-dose sugar substitutes.
