A new study from the University of Michigan Stroke Program finds that ICH patients who had a do-not-resuscitate order issued in the first 24 hours or had care withdrawn were twice as likely to die. Early limitations on care may be an overlooked factor in calculating ICH survival odds, according to researchers.
A three-year study found that patients with bleeding strokes received significantly less cholesterol-lowering medications, diabetes medication, and weight-loss management compared to those with ischemic strokes. Smoking cessation therapy also showed significant disparity between the two groups.
A University of Kentucky study finds that doses higher than a baby aspirin may not prevent cardiovascular events and increase bleeding risk. The research suggests that using the minimum effective dose of 75-81 mg may be optimal for most patients.
Research shows that elderly patients (90+ years) who receive recommended treatments for acute coronary syndromes have better survival rates, but at a higher risk of bleeding complications. Guidelines must be balanced to balance survival benefits with increased bleeding risk.
A new UCSF study predicts a woman's chance of undergoing a hysterectomy based on symptoms and medical history. The study found that women with a combination of symptoms, lack of symptom resolution, and previous GNRH agonist use are more likely to undergo the procedure.
Endoscopic ligation is cost-effective for cirrhotic patients if quality-adjusted life years are considered. Ligation prevents more deaths and episodes, but is not as cost-effective when only life-years are considered.
A new thrombin-receptor antagonist (TRA) has shown significant reduction in serious cardiovascular events, mainly heart attacks, with no increase in bleeding risks in a high-risk patient population. The study found a 46% lowering in serious cardiovascular events, an early and strong efficacy signal for this novel antiplatelet compound.
Researchers found that older mothers with normal, full-term pregnancies were more likely to undergo Caesarean delivery than younger women with similarly low-risk pregnancies. Women giving birth for the first time were six times more likely to deliver by Caesarean.
A study found that routine upstream administration of platelet glycoprotein IIb/IIIa inhibitors reduced composite ischemia events, while deferred selective use resulted in fewer major bleeding complications. However, the criterion for noninferiority was not met.
A recent study using MRI found that 26% of vaginally delivered babies had small bleeds in and around the brain. The bleeds were likely caused by pressure on the skull during delivery. Most bleeds resolve over time without issues, but larger ones may cause problems later in childhood.
