眼皮黃斑瘤與心肌梗塞、中風風險增加相關

Quick Look

研究發現,眼皮周圍出現黃色隆起(黃斑瘤)的人,心肌梗塞、中風及短暫性腦缺血發作的發生率較高,風險差距可持續長達10年。

Why It Matters

黃斑瘤是眼睛周圍出現黃色斑塊或隆起的皮膚病灶,主要由膽固醇等脂肪物質聚集形成,常與血液中膽固醇偏高同時出現。

〔編譯陳成良/綜合報導〕眼科〕眼皮周圍若出現一小塊黃色隆起,除了影響外觀,也可能和未來心肌梗塞、中風風險有關。美國史丹佛大學等研究人員分析近3.6萬人健康資料後發現,有「黃斑瘤」(xanthelasma)的人,心肌梗塞、中風及短暫性腦缺血發作的發生率都較高,而且差距持續到10年。

科學新聞網站《Science Alert》報導,這項刊登於《動脈硬化》(Atherosclerosis)的研究,從大型電子病歷資料庫找出1萬7925名被診斷有黃斑瘤的成年人,再以1萬7925名沒有黃斑瘤的人作為對照。兩組都排除過去曾發生心肌梗塞、中風或短暫性腦缺血發作的人,研究人員並追蹤兩組在1年、5年及10年的情況。

請繼續往下閱讀...

研究發現,第一年內,黃斑瘤患者有1%發生心肌梗塞,對照組為0.35%;中風則是0.95%對0.30%;短暫性腦缺血發作,也就是俗稱的「小中風」,則為0.60%對0.19%。換算實際人數,黃斑瘤組第一年有178人發生心肌梗塞,對照組為63人。

風險差距一路看到10年

到了第5年,黃斑瘤組心肌梗塞發生率為2.26%,對照組1.13%;中風為2.25%對1.03%;短暫性腦缺血發作為1.60%對0.74%。第10年時,心肌梗塞為3.13%對1.73%,中風為3.00%對1.53%,短暫性腦缺血發作則為2.00%對1.13%,差距仍然存在。

黃斑瘤是一種眼睛周圍出現黃色斑塊或隆起的皮膚病灶,主要是膽固醇等脂肪物質聚集在皮膚下形成。《Science Alert》指出,這種情況常與血液中的膽固醇偏高同時出現,但並非所有患者都有異常血脂。研究資料也顯示,黃斑瘤患者中,總膽固醇、低密度脂蛋白膽固醇及三酸甘油脂偏高者約占6成。

研究團隊提醒,黃斑瘤與心肌梗塞、中風之間究竟存在何種關係,仍需要進一步研究。研究結果呈現的是兩者之間的關聯,而不是證明眼皮上的黃色斑塊本身會造成心肌梗塞或中風。研究人員認為,黃斑瘤有可能成為醫師評估心腦血管風險時可參考的臨床指標。

Food consistency affects satiety. Weight loss requires attention to form rather than just calories.

Li Sixian, a physician at Linhao Western Medicine Clinic, pointed out that food viscosity will affect gastric emptying and GLP-1 secretion, thereby changing satiety and subsequent food intake. Research shows that those who drink the thickest drinks eat about 12% less pizza, and the satiety caused by liquid calories is only about half that of solid food. He reminded that weight loss should not only focus on caloric intake, but food type is also very important, and clarified that the thick food referred to did not refer to food thickened with starch to increase the concentration.

Asking about health | Will eating egg yolks really increase blood lipids? If you abandon it, you will lose valuable nutrients.

Experts point out that cholesterol in food is different from human blood cholesterol, and discarding egg yolks can easily lead to nutrient loss. The increase in blood lipids is mainly affected by the intake of saturated fatty acids, trans fatty acids and sugar. It is recommended to eat a balanced diet rather than a single taboo of egg yolk.

Xinhua Viewpoint丨How to make medical reimbursement more secure for flexible employees

Seven departments including the National Medical Insurance Administration jointly issued a notice to launch a special campaign to improve the quality of basic medical insurance for key groups such as flexible employees. Through measures such as lowering the insurance threshold, flexible payment rules, and opening up medical insurance conversion channels, the medical insurance participation rate of employees with flexible employment will be increased to increase the reimbursement ratio and security level, and alleviate the problem of expensive and difficult medical treatment for workers in new employment forms such as takeaway riders.
