研究孕婦感染新冠或影響嬰兒腦發育,糖尿病或增加新冠后遺癥風險

路透社6月10日刊文總結了關于新冠病毒的最新科學研究。多個研究表明，糖尿病可能增加長期新冠的風險。糖尿病患者出現長期新冠癥狀的可能性是非糖尿病患者的四倍。還有研究發現，女性孕期感染新冠，其后代出現大腦發育問題的風險可能高于平均水平。報道稱，其中一些研究結果需進一步證實，還需進行同行審議。現將文章內容摘編如下：

Diabetes may increase long COVID risk

糖尿病可能增加新冠后遺癥風險

Diabetes may increase the risk of long COVID, new analyses of seven previous studies suggest.

對此前七項研究的最新分析表明，糖尿病可能增加新冠后遺癥的風險。

Researchers reviewed studies that tracked people for at least four weeks after COVID-19 recovery to see which individuals developed persistent symptoms associated with long COVID such as brain fog, skin conditions, depression, and shortness of breath. In three of the studies, people with diabetes were up to four times more likely to develop long COVID compared to people without diabetes, according to a presentation on Sunday at the annual Scientific Sessions of the American Diabetes Association.

研究人員回顧了對康復四周以上的新冠感染者進行跟蹤調查的研究，以了解哪些人出現了腦霧、皮膚問題、抑郁和呼吸短促等持續的新冠后遺癥。6月5日，在美國糖尿病協會年度科學會議上發表的一份報告顯示，在其中三項研究中，糖尿病患者出現新冠后遺癥的可能性是非糖尿病患者的四倍。

The researchers said diabetes appears to be "a potent risk factor" for long COVID but their findings are preliminary because the studies used different methods, definitions of long COVID, and follow-up times, and some looked at hospitalized patients while others focused on people with milder cases of COVID-19.

研究人員表示，糖尿病似乎是導致新冠后遺癥的“一個重要風險因素”，但研究發現是初步的，因為幾個研究使用了不同的方法、對新冠后遺癥的定義和隨訪時間不同，一些研究對象是住院新冠患者，而另一些研究對象是輕癥新冠患者。

"More high-quality studies across multiple populations and settings are needed to determine if diabetes is indeed a risk factor" for long COVID, the researchers said. "In the meantime, careful monitoring of people with diabetes... may be advised" after COVID-19.

研究人員表示，“需要在多個群體和環境中進行更多高質量的研究，以確定糖尿病是否確實是新冠后遺癥的風險因素”。“同時，建議對感染過新冠的糖尿病患者進行詳細監測……”。

COVID-19 in pregnancy linked with babies learning skills

孕期感染新冠影響嬰兒學習能力

Babies born to mothers who had COVID-19 while pregnant may be at higher than average risk for problems with brain development involved in learning, focusing, remembering, and developing social skills, researchers have found.

研究人員發現，孕婦感染新冠，其嬰兒在學習、專注力、記憶和培養社交技能方面出現大腦發育問題的風險可能高于平均水平。

They studied 7,772 infants delivered in Massachusetts between March and September 2020, tracking the babies until age 12 months. During that time, 14.4% of the babies born to the 222 women with a positive coronavirus test during pregnancy were diagnosed with a neurodevelopmental disorder, compared to 8.7% of babies whose mothers avoided the virus while pregnant. After accounting for other neurodevelopmental risk factors, including preterm delivery, SARS-CoV-2 infection during pregnancy was linked with an 86% higher risk of a neurodevelopmental disorder diagnosis in offspring, the researchers reported on Thursday in JAMA Network Open. The risk was more than doubled when the infection occurred in the third trimester.

他們的研究對象是2020年3月至9月在馬薩諸塞州分娩的7772名嬰兒，對這些嬰兒進行追蹤研究直到他們滿一周歲。在此期間，222名新冠病毒檢測呈陽性的孕婦所產嬰兒中有14.4%被診為神經發育障礙，而未感染新冠病毒的孕婦所產嬰兒中只有8.7%。研究人員6月9日在《美國醫學會雜志網絡開放》上發文稱，在考慮了早產等其他神經發育風險因素后，女性孕期感染新冠病毒，其后代的神經發育障礙確診風險高86%。當感染發生在妊娠晚期時，這種風險增加了一倍多。

The researchers point out that their study was brief and cannot rule out the possibility that additional neurodevelopmental effects will become apparent as the children grow up. On the other hand, they note, larger and more rigorous studies are needed to rule out other potential causes and prove that the coronavirus is to blame.

研究人員指出，這些研究時間很短，不能排除隨著嬰兒的成長，其他神經發育影響可能會變得明顯。另一方面，他們指出，需要進行更大規模和更嚴格的研究，以排除其他潛在原因，并證明新冠病毒是罪魁禍首。
