Inherited genetic variants play crucial role in cancer development and behavior

A new multicenter study by researchers at the Icahn School of Medicine at Mount Sinai, in collaboration with the National Cancer Institute-funded Clinical Proteomic Tumor Analysis Consortium (CPTAC) and colleagues around the world, has discovered that the genes we are born with-known as germline genetic variants-play a powerful, underappreciated role in how cancer develops and behaves.

Do disasters delay early cancer diagnoses?

Rates of colorectal cancer (CRC) diagnoses dropped during and shortly after Hurricanes Irma and Maria and the COVID-19 pandemic in Puerto Rico, according to a recent analysis. However, late-stage diagnoses eventually exceeded expectations, suggesting that limited access to cancer screening services due to these disasters likely hindered timely CRC diagnoses. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.

Lithium shifts circadian rhythms early in bipolar disorder and may offer clues to treatment response

A randomized controlled trial shows that lithium treatment in bipolar disorder patients reduces daytime activity, advances its onset time, and increases volatility in circadian rest-activity patterns. These changes appear early and independently of mood, offering promise as early biomarkers of treatment response.

Blood test detects Parkinson’s years before symptoms appear using RNA markers

A new study identifies a blood-based biomarker that detects pre-symptomatic Parkinson’s disease by measuring the ratio of specific nuclear and mitochondrial transfer RNA fragments. The test outperforms standard clinical tools and may also reflect disease mechanisms related to impaired protein synthesis.

Multidimensional sleep health linked to better cardiometabolic outcomes

Healthy sleep includes multiple components, such as number of hours of sleep per night, how long it takes to fall asleep, daytime functioning and self-reported sleep satisfaction, and addressing these different dimensions of sleep may help to reduce cardiometabolic health and related risk factors, according to a new American Heart Association scientific statement published today in Circulation: Cardiovascular Quality and Outcomes.
