A nationwide study has found that chromosomal microarray testing detects additional genetic abnormalities in about 1 in 70 normal karyotype samples and 6% of cases with structural abnormalities. The new test may soon replace standard karyotyping for prenatal testing, providing more information on potential disorders.
Outcomes for unruptured brain aneurysms treatment have remained stagnant over the last 10 years, attributed to minimally invasive endoscopic coiling procedures at lower-volume community hospitals. These procedures lead to inferior outcomes and increased technical shortcomings or errors in judgment.
A pilot study found that 60% of children who received liver tissue from a parent can safely discontinue immunosuppression. The study identified three clinical factors that predict which pediatric liver transplant patients are most likely to do well if the medications are withdrawn.
Researchers from NY Presbyterian/Columbia University Medical Center present studies on the prevalence of colorectal adenomas in racial and ethnic minorities, finding higher rates among blacks and Hispanics. Additionally, a study on single operator choledochoscopy reveals low interobserver agreement and accuracy among experts, highlight...
A multicenter study published in the New England Journal of Medicine shows that transcatheter aortic-valve implantation resulted in significantly lower rates of death among patients who cannot undergo surgery. The procedure demonstrated safety and effectiveness for this life-threatening illness in unsuitable candidates.
A new study by NewYork-Presbyterian Hospital/Columbia University Medical Center researchers found that the birth control pill works equally well in women with obesity and thinner women. The study's findings strengthen the message to patients that the pill will only work if it is taken every day.
A pilot study published in the Journal of Endourology suggests that CO2 laser technology used with robotic prostate cancer surgery may preserve sensitive nerve areas necessary for erections and urinary continence. The technology, known as BeamPath, was found to be easy to manipulate and accurate.
Physician-scientists from NewYork-Presbyterian Hospital/Weill Cornell Medical Center present several studies at the 2010 American Urological Meeting, including a potential breakthrough in using 5-alpha reductase inhibitors to improve PSA test accuracy for prostate cancer diagnosis. Additionally, they present results on robotic surgery ...
A new study published in the New England Journal of Medicine found that vitamin E improved features of nonalcoholic steatohepatitis (NASH), an obesity-related chronic liver disease. After 96 weeks of treatment, 43% of those treated with vitamin E met the primary endpoint compared to 19% of those who received a placebo.
Researchers have identified key eye characteristics to determine which premature infants are most likely to benefit from early treatment for retinopathy of prematurity, resulting in improved vision and reduced risk of blindness. This new approach aims to improve the lives of thousands of children born prematurely each year.
Researchers found a gene expression test reduced biopsies and was safe, resulting in similar two-year outcomes as traditional biopsies, and was preferred by patients. The test measures 11 genes associated with heart transplant rejection, reducing the need for invasive heart muscle biopsies.
A study found that transforming growth factor B1 (TGF-B1) is higher in blacks compared to whites, increasing the risk of hypertension and renal disease. Higher levels of TGF-B1 are also linked to body mass index and metabolic syndrome.
A new study finds that laparoscopic gastric banding surgery can improve and even reverse metabolic syndrome in obese adolescents, lowering their risk for future cardiovascular disease and diabetes. The procedure reduces weight, waist circumference, and blood levels of C-reactive protein and other markers of the condition.
A study by researchers at NewYork-Presbyterian Hospital/Columbia University Medical Center has found no statistically significant increase in hypospadias rates in New York State during the 1992-2005 period, contradicting earlier concerns about environmental chemicals. Maternal age is a significant risk factor for the birth defect.
Physician-scientists presented new research on minimizing steroid exposure for liver transplant patients with hepatitis C, hypothermic machine perfusion vs. cold storage for preserving donor livers, and the effectiveness of neutrophil-lymphocyte ratio in predicting colorectal liver metastases. The studies aimed to improve patient outco...
The DuraHeart system is designed for severe left-ventricular heart failure, helping patients sustain life while awaiting a heart transplant. The device, developed by Terumo Heart Inc., has been successfully implanted in three US patients.
A new study finds that radiofrequency ablation can completely reverse Barrett's esophagus and reduce the risk of esophageal cancer. The procedure, which involves targeted thermal energy, showed significant success in treating patients with dysplastic Barrett's esophagus.
A landmark study published in NEJM found that paclitaxel-eluting stents significantly reduce target lesion revascularization and binary angiographic restenosis rates compared to bare-metal stents. The study showed a lower rate of ischemia-driven target-lesion revascularization at 12 months with the use of paclitaxel-eluting stents.
A new surgical procedure called OCRPRC (OsteoChondral Resurfacing in Proximal Row Carpectomy) offers a promising alternative to traditional treatments for wrist arthritis. By reducing inflammation and improving cartilage status, the procedure aims to restore wrist function and alleviate pain.
Researchers have successfully treated HIV-seropositive women with assisted reproduction, achieving pregnancies and stable infant outcomes. Additionally, studies found that SC Ovidrel can be reliably used for egg-cell donation and pregnancy is possible in breast cancer patients after chemotherapy, despite reduced fertility.
A new study reveals significant variations in prostate cancer care quality by region, hospital type, and race, suggesting areas for improvement to enhance patient outcomes. Compliance rates with standardized measures vary greatly among healthcare facilities, highlighting the need for standardization.
Teenagers who underwent minimally invasive gastric banding surgery experienced significant improvements in abdominal fat, triglyceride levels, blood sugar control, liver function, and immune response. After six months, they lost an average of 20 pounds.
Researchers from NewYork-Presbyterian Hospital/Columbia University Medical Center presented findings on the effectiveness of drug-eluting stents in preventing restenosis. The studies also explored the safety and efficacy of bivalirudin for patients undergoing primary angioplasty, particularly those with diabetes and advanced age.
Researchers identified naturally occurring antibodies in human blood that selectively target toxic beta amyloid oligomers, potentially offering a natural defense mechanism against Alzheimer's. The antibodies recognize misfolded shapes of proteins, which could have implications for immune therapy of other neurodegenerative diseases.
