Scientists use living muscle to reanimate paralyzed organs

What if a technology could reanimate parts of the body that have lost their connection to the brain - like a bladder that can no longer empty due to a spinal cord injury, or intestines that can't push food forward due to Crohn's disease? What if this technology could also send sensations such as hunger or touch back to the brain?

Swimming in treated pools safe for children with tympanostomy tubes

A new study published in Otolaryngology−Head and Neck Surgery, the peer-reviewed journal of the American Academy of Otolaryngology−Head and Neck Surgery Foundation (AAO-HNSF), finds that children with tympanostomy tubes who swim in treated pools are not at increased risk of ear drainage, while those exposed to untreated or natural bodies of water face significantly higher odds of developing recurrent otorrhea.

Dual imaging reveals hidden causes of heart attacks without blockages

When Ashley Perlow felt a sharp pain shoot across her chest and into both wrists, she didn't think it could be a heart attack. She was 36, a new mom, and otherwise healthy.

PSMA therapy may postpone hormone treatment in prostate cancer patients

Where previous research showed that PSMA therapy for prostate cancer can prolong the lives of patients who have exhausted all other treatment options, a new study now demonstrates that the therapy is also effective in an earlier stage of the disease.

Study links atrial fibrillation to poorer brain clearance and cognitive decline

Researchers found that people with atrial fibrillation had lower MRI-based glymphatic activity and poorer cognitive performance than healthy controls, with the greatest impairment seen in non-paroxysmal AF. In patients who underwent catheter ablation, glymphatic activity improved after sinus rhythm was restored, suggesting a possible link between heart rhythm, brain waste clearance, and cognition.

Inside the high-stakes corporate fight over feeding preterm babies

In 2013, a scientist at Abbott Laboratories saw study results with potentially big implications for the company's profits and the lives of some of the world's most fragile people: preterm infants.

Transcatheter valve-in-valve procedure improves short-term outcomes in high-risk patients

In patients with a poorly functioning bioprosthetic mitral valve in the heart, a minimally invasive procedure to insert a new valve was associated with a lower rate of death or disabling stroke within one year, compared with patients who underwent standard repeat mitral valve replacement surgery, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Novel vFFR method performs similar to invasive coronary assessment

A novel, minimally invasive method of determining whether fatty deposits in a coronary artery are restricting blood flow to a patient's heart performed similarly to the standard, more-invasive procedure in a large multi-country European randomized trial presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

AI-based tool matches standard method for coronary blood flow assessment

A novel, minimally invasive computer software-based method that uses artificial intelligence to determine whether plaques in a coronary artery are restricting blood flow to the patient's heart performed similarly to the standard, more invasive wire-based procedure, according to a large international randomized trial presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Angioplasty improves symptoms in chronic total coronary occlusion patients

In what is believed to be the first randomized placebo-controlled trial of its kind, patients with a chronic total blockage of a coronary artery who received a nonsurgical procedure to reopen the artery showed statistically significant reductions in chest pain and improvements in quality of life compared with patients who received a placebo procedure.

Hypercortisolism found in many patients with resistant hypertension

The MOMENTUM study found 27 percent of patients with resistant hypertension have hypercortisolism. This is a significant finding, demonstrating that hypercortisolism is more common in these patients than previously understood by researchers and clinicians.

Microaxial flow pump fails to reduce heart damage in STEMI trial

Using a microaxial flow pump prior to and during cardiac stenting procedures for patients with severe heart attacks who don't have cardiogenic shock does not significantly reduce heart damage.

New mother’s experience highlights importance of postpartum heart care

At 35, Brooklyn resident Luyba Caloras was healthy, with no history of heart problems and no reason to think she was at risk of them. But pregnancy can act as a stress test on the heart—and soon after delivering her son at NYU Langone Health on February 3, 2024, she was diagnosed with a complication she never expected.
