針對33萬名美國退伍軍人第2型糖尿病患者的觀察性研究發現,GLP-1類藥物持續使用3年可使重大心血管事件風險降低18%,但中斷治療後重新用藥者風險降幅縮小至12%,停藥1年未重啟者風險增加14%,停藥2年者增加22%,顯示用藥中斷時間與心血管風險呈正相關。

〔編譯陳成良/綜合報導〕俗稱「瘦瘦針」的GLP-1受體促效劑原本就是治療第2型糖尿病的藥物,近年也因減重效果受到廣泛使用。一項追蹤逾33萬名第2型糖尿病患者的大型研究發現,GLP-1藥物中斷時間越長,與重大心血管事件風險的差距越大。
科學新聞網站《Science Daily》報導,這項由美國聖路易斯華盛頓大學醫學院團隊主導、發表於醫學期刊《BMJ Medicine》的研究,分析33萬3687名美國退伍軍人的用藥與健康資料,追蹤最長3年。研究對象全數患有第2型糖尿病,研究人員藉由比較GLP-1藥物持續使用、中斷及停藥等情況,觀察心肌梗塞、中風與死亡等重大心血管事件的發生情形。

分析顯示,持續使用GLP-1藥物3年者,重大心血管事件風險較使用另一類降血糖藥物磺醯脲類(sulfonylureas)者低18%。但相較持續用藥者,中斷治療6個月後重新用藥者,重大心血管事件風險高4%至8%;停藥1年未重啟者高14%,停藥2年者則高22%。
研究對象是糖尿病患者 不是單純減重族群
研究也發現,曾中斷GLP-1治療、之後重新用藥者,相較持續使用3年者,心血管風險的降幅較小。持續用藥者的風險降幅為18%,中斷後重新用藥者平均為12%,顯示用藥中斷時間越長,與重大心血管事件風險的差距越大。
不過,這項研究屬於觀察性資料分析,無法證明停藥直接造成心肌梗塞或中風增加。研究對象平均約66歲且以男性為主,全數都是第2型糖尿病患者,並未針對不同GLP-1藥物或不同適應症分別分析。因此,這項結果不能直接套用到沒有糖尿病、單純為減重而使用GLP-1藥物的族群。

Allergies are not limited to childhood, anyone can develop new allergies suddenly at any stage of life due to factors such as coronavirus infection, antibiotic use, pregnancy or tick bites. Studies have shown that the new coronavirus will increase the risk of allergic rhinitis and asthma, while vaccines can reduce the risk; antibiotics may damage the intestinal microbiota and cause immune system confusion; hormonal fluctuations during pregnancy and menopause may also trigger allergies; being bitten by the lone star tick may trigger alpha-galactose syndrome, making people allergic to red meat. While some allergies, such as rhinitis of pregnancy, disappear after childbirth, many new allergies may be permanent, and scientists are exploring probiotics, vaccines and single-dose antibody therapies to retrain the immune system.

Although Nantou County is rich in ecology and receives an average of 2,500 to 3,000 snake catching notifications each year, currently none of the county's 6 responsible hospitals and 5 health clinics have the rare venomous chain snake serum. Health Director Chen Nansong said that there are very few patients bitten by chain snakes in the country every year, and the serum is only installed in Taichung Rongzong. Councilor Zhang Wanci called for active efforts to obtain distribution to ensure public safety.

During the Mid-Autumn Festival, there are many fire accidents caused by pets biting lithium batteries of children's toys, unquenched mosquito coils or power banks out of curiosity. Similar cases have occurred in Jingzhou, Hubei, Jiujiang, Jiangxi and Beijing. The fire department reminds families with pets to properly store flammable and explosive items, clean up debris regularly, lock kitchen doors, take care of heating equipment, prepare emergency escape kits, and cut off power and gas when going out to prevent pets from mishandling fires.

Waking up in the middle of the night to check the time will trigger anxiety and stress reactions, causing the more you look, the more you will wake up, forming a vicious cycle. Research shows that people who watch the clock tend to overestimate how long they have been awake and suffer from more insomnia. Physical isolation clocks, fixed wake-up times, cognitive conditioning, and relaxation training are recommended to break conditioned arousal.

On the occasion of the 69th International Day of the Deaf, experts pointed out that about 220 million people in my country have hearing loss. Sudden deafness is trending younger. People aged 20 to 35 who stay up late and are under high pressure are at high risk. The window period for treatment is short. The probability of hearing recovery is significantly reduced with every day of delay. At the same time, there are misunderstandings in wearing hearing aids, which require regular debugging, and be wary of noise overstretching the ears for safe listening time.

Recently, a video of the "Flying Step" originated from the Huagudeng dance in Anhui became popular on the Internet, triggering a large number of netizens and celebrities to imitate it. However, blindly following the trend of practice has led to many hospitals receiving knee injuries in young patients, mainly cruciate ligament strains or even tears. The article points out that although Internet celebrity moves such as "Flip Step", "Cross-legged Holding Pillar" and "Lying Fish" are interesting, ordinary people can easily cause knee joint injuries due to lack of professional training and warm-up. It also provides knee joint protection suggestions such as weight control, nutritional supplements, warmth, avoiding prolonged sitting, and elastic band training.
