( New research from Memorial Sloan Kettering Cancer Center (MSK) investigates a promising approach against diabetic retinopathy and finds patients with early-onset colorectal cancer likely don’t need more frequent surveillance colonoscopies.

Anti-ceramide immunotherapy promising against diabetic retinopathy, animal studies suggest Diabetic retinopathy is a condition that affects blood vessels in people with diabetes and can cause blindness. Now a new study from a team at MSK, Michigan State University, and the University of Oklahoma Health Sciences Center shows that diabetic retinopathy can be considered a “ceramidopathy” — which can be reversed with anti-ceramide immunotherapy. The group — overseen by Richard Kolesnick, MD, of the Sloan Kettering Institute, and Julia Busik, PhD, of the University of Oklahoma — found that in patients with advanced diabetic retinopathy, there is an imbalance of ceramides in the eye. Too much of these lipids leads to inflammation and cell death in the blood vessels of the eye. Moreover, the researchers showed in animal models that antibodies that act against ceramides can protect against diabetic retinopathy. Their findings suggest that targeting ceramides could be a potential treatment for diabetic retinopathy, both in the disease’s early stages to prevent progression and in more advanced stages. in Cell Metabolism.

Early-onset colorectal cancer patients don’t need more frequent surveillance colonoscopies A new study led by MSK gastroenterologist Robin Mendelsohn, MD, suggests that early-onset colorectal patients, who are diagnosed before age 50, do not require more frequent surveillance colonoscopies compared with older average-onset colorectal patients. The study included 612 early-onset patients and 647 average-onset patients, and found the younger group had a 29% lower risk of developing advanced neoplasms from the time of initial surgery to first surveillance colonoscopy — which was 12.6 months for both cohorts. Subsequent colonoscopies also showed a lower risk.

This study is believed to be the largest of its kind for early-onset patients, for whom there currently aren’t colonoscopy guidelines. The results support the idea that young patients can follow the same surveillance guidelines as older patients.  “The incidence of early onset colorectal cancer is rising,” Dr. Mendelsohn notes. “This study suggests this younger patient group does not need more aggressive surveillance, which would benefit them by reducing costs and disruptions to life and the risks posed by unneeded exams.” in Clinical Gastroenterology and Hepatology.

ASCO: Large precision oncology study identifies differences in prostate cancer genomics among a racially and ethnically diverse cohort of U.S. veterans

FINDINGS A new study led by a UCLA-VA collaborative team looking at the landscape of genomic alterations in more than 5,000 veterans with metastatic prostate cancer uncovered differences in the genomic makeup of cancer cells that were associated with race and ethnicity.  Although the team found that a similar set of cancer-related genes were altered in both non-Hispanic Black and non-Hispanic white veterans, the frequencies that these alterations were observed at varied significantly ...

ASCO: Combination therapy significantly improves outcomes for patients with metastatic colorectal cancer

FINDINGS A study led by UCLA Health Jonsson Comprehensive Cancer Center researchers found that using a combination of experimental immunotherapy drugs with chemotherapy significantly improves progression-free survival and overall survival for patients with metastatic colorectal cancer who have previously undergone standard chemotherapy treatment when compared to those who received the targeted therapy regorafenib alone. The median progression-free survival, which is the amount of time during and after treatment when the cancer does not worsen or progress, with the combination treatment was 6.2 months compared to 2.1 months for those ...

Euclid space mission releases first scientific results and new images of the cosmos

Euclid space mission releases first scientific results and new images of the cosmos
European space mission Euclid has released early scientific papers based on observations made by the space telescope, along with five new astronomical images of the Universe, as the project sets about unravelling the secrets of the cosmos. The new images are part of Euclid’s Early Release Observations (EROs) and accompany the mission’s first scientific data and 10 forthcoming science papers. Their publication comes less than a year after the space telescope’s launch and some six months after it returned its first full-colour ...

Sociodemographic heterogeneity in the associations of social isolation with mortality

About The Study: Social isolation was associated with increased risks of all-cause, cardiovascular diseases, and malignant neoplasm mortality, with associations varying across populations. This study fills an important gap in research on social isolation, emphasizing its varied associations across demographic and socioeconomic groups.  Corresponding Author: To contact the corresponding author, Atsushi Nakagomi, M.D., Ph.D., email To access the embargoed study: Visit our For The Media website at this link (doi:10.1001/jamanetworkopen.2024.13132) Editor’s Note: Please ...

Research spotlight: Virtual scribes reduced physicians’ time spent on electronic health records

Research spotlight: Virtual scribes reduced physicians’ time spent on electronic health records
Lisa Rotenstein, MD, of the Department of Medicine at Brigham and Women’s Hospital, is the lead author of a new study published in JAMA Network Open, “Virtual Scribes and Physician Time Spent on Electronic Health Records.” What question were you investigating? We sought to understand the impact of virtual scribes (human scribes who are not physically present in the exam room with the physician and patient) on how physicians spend their time and which characteristics are associated with physicians responding best to scribes. What methods or approach did you use? We studied the experiences of 144 physicians across specialties treating patients ...

Duke-NUS researchers develop new light-controlled ‘off switch’ for brain cells

Duke-NUS researchers develop new light-controlled ‘off switch’ for brain cells
Researchers from Duke-NUS Medical School have found that a new class of light-sensitive proteins are capable of turning off brain cells with light, offering scientists an unprecedentedly effective tool to investigate brain function. The study, recently published in Nature Communications, opens exciting new opportunities to apply optogenetics to investigate the brain activity underlying neurodegenerative and psychiatric disorders such as Parkinson’s disease and depression. Optogenetics is a technique where specific cells are bioengineered to include light-sensitive proteins that act as switches, allowing ...

Liver lesions at risk of transformation into hepatocellular carcinoma in cirrhotic patients

Liver lesions at risk of transformation into hepatocellular carcinoma in cirrhotic patients
Hepatocellular carcinoma (HCC) represents a significant global health burden as one of the most common malignancies in individuals with chronic liver disease or cirrhosis. This malignancy evolves through a multistep process, beginning with dysplastic nodules (DNs) and early HCC, progressing to overt HCC. Recent advancements in liver imaging, particularly the use of hepatocyte-specific contrast agents, have enhanced the detection of these precursor lesions, known as borderline hepatic nodules. These nodules, especially those hypointense in the hepatobiliary phase (HBP) without arterial phase hyperenhancement (APHE), present ...

Update on the STING signaling pathway in developing nonalcoholic fatty liver disease

Update on the STING signaling pathway in developing nonalcoholic fatty liver disease
Nonalcoholic fatty liver disease (NAFLD) has become the most prevalent chronic liver condition worldwide, affecting about 25% of the global population due to the increasing rates of obesity and metabolic syndrome. NAFLD encompasses a spectrum of liver conditions ranging from simple hepatic steatosis to nonalcoholic steatohepatitis (NASH), which can progress to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). Despite its prevalence, there are limited effective treatment options available. Inflammation driven by metabolic disturbances is a key factor in the development and progression of ...
