なぜ女性の2型糖尿病の診断は男性より遅れるのか

1 week ago | wired.jp | Lori Youmshajekian

統計的には、男性のほうが女性よりも2型糖尿病と診断されやすい。全世界でこの疾患を抱えて暮らす男性の数は女性より1,800万人も多いという。しかし、これは物事の一面にすぎない。女性が2型糖尿病と診断されるとき、男性患者に比べて年齢が高いことが多く、体脂肪量も増加している場合が多い。糖尿病に関連した原因（特に心臓疾患）で死亡する確率も、女性患者のほうが高い。一部の研究者は、過小診断がこのギャップの一部を説明するかもしれないと考えている──女性において、より多くの症例が見逃されているのではないか、と。検査方法に潜む課題この不均衡の謎に取り組むため、研究者たちは女性患者の診断の遅れと予後の悪さに寄与する生物学的ならびに社会的性差の解明を進めようと試みている。一部の研究者は、治療とライフスタイルの変化の影響が現れやすい早期のうちに発病リスクの高い女性を発見するため、医療者たちが糖尿病の検査の実施方法を変えるときが来ていることを示唆する。...

Why Women With Type 2 Diabetes Are Diagnosed Later Than Men

1 month ago | wired.com | Lori Youmshajekian

Statistically, men are more likely than women to be diagnosed with type 2 diabetes, with about 18 million more men living with the condition worldwide. This doesn’t tell the whole story. When women do get a diagnosis, they’re often older and have a higher body fat mass. They’re also more likely to die from diabetes-related causes, especially heart disease. And some researchers think underdiagnosis might explain part of the gap—perhaps more cases are being missed in women.
Dozens of Elsevier papers retracted over fake companies and suspicious authorship changes

1 month ago | retractionwatch.com | Lori Youmshajekian

Since March of last year, Elsevier has pulled around 60 papers connected to companies in the Caucasus region that don’t seem to exist. The retraction notices attribute the decision to suspicious changes in authorship and the authors being unable to verify the existence of their employers. Online sleuths have also flagged potentially manipulated citations among the articles. Each of the retracted papers appears to follow an identical pattern, based on the details given in the retraction notices.
People on Ozempic start disliking meat and fried foods. We're starting to learn why.

1 month ago | livescience.com | Lori Youmshajekian

For most of her life, Alyssa Fraser took comfort in cooking. Fraser, a former food reporter from Minnesota, used to relish the process of whipping up her favorite chicken and vegetable recipe or batches of pasta. But after she started taking the popular weight-loss medication Wegovy, her culinary interests seemed to disappear because she became disinterested in food — and certain types of food became particularly off-putting.
De meeste mensen stoppen na twee jaar met Ozempic. Wat gebeurt er dan met je gewicht en gezondheid?

1 month ago | eoswetenschap.eu | Lori Youmshajekian

Afvalmedicijnen zoals Ozempic zijn ontwikkeld als levenslange behandelingen. Een nieuwe studie heeft in kaart gebracht dat de meeste mensen het medicijn na twee jaar niet meer gebruiken. Welke impact heeft dat? Medicijnen die gewichtsverlies bevorderen, zoals semaglutide – bekend onder de merknamen Wegovy en Ozempic – zijn razend populair geworden voor de behandeling van obesitas. Ze zijn vooral effectief als mensen ze eeuwig blijven innemen. Dat is iets dat in de praktijk niet gebeurt.
Former Italian university head faces retractions and criminal investigations

2 months ago | retractionwatch.com | Lori Youmshajekian

A prominent Italian pharmacologist under investigation for embezzlement and rigging university contracts has garnered a dozen and a half retractions in the last year for image alterations and duplications. But Salvatore Cuzzocrea, the former rector of the University of Messina, told us he did not agree with the retractions because they were decided “without clear communication,” and that none of the papers had problems that he wasn’t able to reply to.
Cortisol rises during intense workouts. Is that really a bad thing?

Mar 12, 2025 | nationalgeographic.com | Lori Youmshajekian

Fitness influencers claim intense workouts such as HIIT or running can spike cortisol and hinder weight loss, while gentler alternatives like walking keep it in check. But cortisol’s role in exercise is far more than simply “good” or “bad.”Often branded as the “stress hormone,” cortisol is blamed for everything from belly fat to burnout. But it plays a crucial role in keeping the body running.
Are Foodborne Illnesses and Deaths in the U.S. Worsening? New Data on Recalls Explain

Mar 11, 2025 | scientificamerican.com | Lori Youmshajekian

Food recalls seemed relentless in the U.S. last year. Cucumbers, eggs, even big-brand products such as McDonald’s Quarter Pounders and Boar’s Head deli meats were implicated in dozens of foodborne illness cases, leaving many questioning whether their favorite foods were safe to eat.
Seven years after ‘noncompliance’ finding, whistleblowers push for retractions

Mar 5, 2025 | retractionwatch.com | Lori Youmshajekian

Seven years after investigations uncovered “serious noncompliance” in the collection of biological samples at a California VA hospital, the original whistleblowers say several papers related to the work use these problematic samples and should be retracted. But the principal investigator of the work says there’s no reason to question the findings.
