Fat around the heart linked to increased risk of heart failure

Researchers found that excess pericardial fat increases the risk of heart failure, even after adjusting for established risk factors. High pericardial fat volume was associated with a double increase in risk for women and a 50% increase for men, according to the study published in the Journal of the American College of Cardiology.

Food dyes may cause disease when the immune system is dysregulated, researchers report

A new study found that artificial food colorants like Red 40 and Yellow 6 can cause disease in mice with dysregulated immune systems, specifically colitis. Researchers are now investigating the potential impact on humans, given that similar cytokine IL-23 dysregulation is a factor in human inflammatory bowel disease.

Mount Sinai ophthalmologists develop new technique to assess progression of sickle cell retinopathy

Researchers used OCT angiography to image patients with sickle cell retinopathy and found that sequential imaging can help assess disease progression and treatment effectiveness. The study showed that untreated patients had more flickering blood vessels, indicating a higher risk of permanent blockage.

Patients hospitalized with COVID-19 have a small risk of heart failure

A new Mount Sinai study found that patients hospitalized with COVID-19 have a small but significant risk of developing heart failure, even without a previous history of heart disease or cardiovascular risk factors. The study's findings may prompt clinicians to monitor for signs of congestive heart failure more closely in these patients.

Mount Sinai study finds that blood clotting drug commonly used for orthopedic surgeries does not increase complications for high-risk patients

A Mount Sinai study of over 40,000 patients reveals that tranexamic acid use in high-risk patients does not increase complications such as deep vein blood clots or strokes. The study confirms prior findings and provides new insights into the safety of the drug when used in high-risk patients undergoing hip and knee replacement surgeries.

Second shot of COVID-19 vaccine may not be necessary in previously infected individuals -- Mount Sinai

Researchers at Mount Sinai found that a single shot of COVID-19 vaccine can provide immunity to individuals who have previously been infected by the virus. This could help stretch limited vaccine supplies and spare individuals from unnecessary side effects of a second dose.

Overweight children exposed to lead in utero may have poor future kidney function

A study published in Environment International found that overweight children exposed to lead in utero and during their first weeks of life are at risk for poorer kidney function in adulthood. The research measured blood levels of lead during pregnancy and eGFR levels in children between 8-12 years old.

Neural pathway critical to correcting behavioral errors related to psych disorders found

Mount Sinai researchers identified a neural pathway that detects errors and guides subsequent behavioral improvement, which is frequently dysregulated in psychiatric disorders. They also suggest that neurostimulation of this brain pathway could provide an important mechanism for attention adjustments following behavioral errors.

Mount Sinai researchers identify mechanisms that are essential for proper skin development

Researchers found that Polycomb repressive complex 1 (PRC1) and Polycomb repressive complex 2 (PRC2) maintain the skin-specific gene expression pattern necessary for proper development of the skin. The study suggests that targeting both complexes may be a more effective form of treatment for certain cancers.

Scientists take important step toward using retinal cell transplants to treat blindness

Researchers successfully transplanted human cadaver-derived retinal pigment epithelium (RPE) into non-human primate models, showing promise for treating macular degeneration and blindness. The study demonstrates the safety and feasibility of this approach, paving the way for potential human clinical trials.

Mount Sinai researchers identify and characterize 3 molecular subtypes of Alzheimer's

Researchers at Mount Sinai identified three major molecular subtypes of Alzheimer's disease using RNA sequencing data from over 1,500 brain samples. These subtypes were independent of age and disease stage and corresponded to different combinations of dysregulated biological pathways leading to brain degeneration.

Repeated ketamine infusions reduce PTSD symptom severity

A study conducted by researchers from the Icahn School of Medicine at Mount Sinai found that repeated ketamine infusions significantly reduced symptom severity in individuals with chronic PTSD. The improvement was rapid and maintained for several weeks afterwards, suggesting this may be a promising treatment option for PTSD patients.

Multi-population risk scores could improve risk prediction for inflammatory bowel diseases, study finds

Researchers developed polygenic risk scores using genetic data from nearly 30,000 individuals, improving IBD predictions across European, Ashkenazi Jewish, Hispanic, and UK Biobank populations. Lower predictive power was seen in African ancestry due to smaller datasets and greater genetic diversity.

Scientists unlock promising key to preventing cancer relapse after immunotherapy

Researchers found that targeting the fas protein can prevent cancer cells from escaping immunotherapies, leading to longer-lasting positive responses and improved survival rates. By combining immunotherapies with small molecule inhibitors, bystander tumor cell killing may be potentiated to eliminate antigen-loss variants.

A novel monoclonal antibody therapy cuts LDL cholesterol by half in a high-risk patient population,

A phase 2 study found that evinacumab reduced LDL cholesterol by 50% in patients with severe hypercholesterolemia resistant to standard treatments. The therapy works through a different mechanism than existing drugs and shows promise for treating refractory hypercholesterolemia.

New insights into facial birth defects are revealed by Mount Sinai researchers

The study, published in Genes and Development, reveals the role of signaling pathways in regulating cell behavior, including proliferation, death, and migration. The research team identified new signaling outputs that function independently of established FGF signal transduction pathways, particularly in cell adhesion.

Mount Sinai develops machine learning models to predict critical illness and mortality in COVID-19 patients

Researchers developed machine learning models predicting critical events and mortality in COVID-19 patients using electronic health records. The models identified key drivers of critical illness, including acute kidney injury and elevated lactate dehydrogenase, and predicted outcomes at various time windows.

Study finds 1.7 million New Yorkers have been infected with SARS-Cov-2 and virus was in NYC earlier than reported

A retrospective surveillance study of over 10,000 plasma samples found that more than 1.7 million New Yorkers have been infected with SARS-CoV-2, indicating the virus was present in the city before the first confirmed case. The infection fatality rate is close to 1 percent, ten times deadlier than the flu.
