This finding sheds light on the mechanisms behind severe bleeding in hemophilia patients and has implications for other cardiovascular disorders.
A large registry study found that patients with low levels of platelet inhibition after receiving a drug-eluting stent are at higher risk for blood clots and heart attacks. However, this responsiveness to clopidogrel was also linked to reduced bleeding complications.
Patients with atrial fibrillation experienced more major and non-major clinically relevant GI bleeding when taking rivaroxaban than warfarin. Major and non-major, clinically relevant bleeding occurred more frequently with rivaroxaban use.
The study found a significant decrease in mortality rate for upper gastrointestinal bleeding, from 4.69% in 1989 to 2.13% in 2009. The proportion of patients undergoing in-hospital endoscopic therapy increased from 2% to 27%, and hospital stays decreased from 4.5 days to 2.8 days.
Research found that antidepressant use, particularly SSRIs, increases the risk of intracranial and intracerebral hemorrhages by 50% and 40%, respectively. However, the actual increased risk for most people is extremely low, occurring at a rate of one additional stroke per 10,000 people per year.
A study of 38 premature babies from low-income families found a higher risk of brain bleeds, fewer follow-up appointments, and more ER visits compared to those from higher-income families. The findings highlight the critical need for better identification of high-risk pregnancies and reduction of premature births.
A study found that vigorous physical activity increases the risk of bleeding in children with moderate or severe hemophilia A or B. Most bleeds associated with physical activity occur within an hour of activity, and the absolute increase in risk may be small.
A new study published in The Lancet found that apixaban is more effective and safer than warfarin for patients with atrial fibrillation and at least one additional risk factor for stroke. This suggests that current risk scoring systems may be less relevant when using apixaban, potentially simplifying treatment decisions.
A recent study published in JAMA found that administering dexamethasone to children before tonsillectomy did not significantly increase post-operative bleeding. The researchers tested the hypothesis that dexamethasone would result in a 5% higher rate of bleeding events compared to placebo, but the results showed no significant difference.
A new study found no significant association between corticosteroid use and increased bleeding events after tonsillectomy. The research suggests that the commonly used corticosteroid dexamethasone does not significantly increase the risk of serious bleeding in children undergoing the procedure.
A study of patients treated with warfarin suggests that resuming therapy after gastrointestinal tract bleeding is associated with a lower risk of blood clots and death. The analysis found that resuming warfarin was linked to a significantly increased risk of thrombosis and death from any cause if therapy was not resumed.
Researchers at London School of Hygiene & Tropical Medicine create comic to highlight life-saving benefits of tranexamic acid (TXA) for trauma patients. The comic aims to appeal to doctors, nurses, and paramedics on the front-line of medicine, promoting awareness about the latest research findings.
A new study published in Neurology finds that people who drink heavily (3+ drinks/day) are at higher risk for stroke almost a decade and a half earlier than those who don't. Heavy drinking is linked to a more severe form of stroke, leading to poorer long-term outcomes.

Researchers from Duke University Medical Center found that tPA is safe to use in acute stroke patients on warfarin, contradicting previous concerns about high intracranial bleeding risk. The study included over 23,000 patients and found similar intracranial hemorrhage risks for those on warfarin and non-warfarin users.
The CHA2DS2-VASc score has been validated in different populations, identifying very low risk patients who do not need antithrombotic therapy. New oral anticoagulants have a greater net clinical benefit compared to warfarin when both bleeding and stroke risks are high.

Researchers found tPA is safe for warfarin-treated stroke patients, with similar bleeding risks regardless of medication use. The study suggests tPA should not be withheld from these patients, as it minimizes brain damage and disability.
A study found the diagnostic yield of colonoscopy for melena after a nondiagnostic upper endoscopy to be 4.8 percent, significantly lower than previously reported. The rate of therapeutic intervention was also very low at 1.7 percent, suggesting that most procedures are diagnostic-only and can be performed on an elective basis.
A Mayo Clinic study reveals that people with rheumatoid arthritis are at a higher risk of developing lower gastrointestinal issues, which can be life-threatening. Smoking, steroid use, and prior abdominal surgery increase the risk, emphasizing the need for new prevention and treatment strategies.
A new study found that the novel oral anti-coagulant rivaroxaban is as effective as traditional treatment for blocked lung blood vessels, with lower rates of major bleeding. The EINSTEIN-PE trial compared rivaroxaban to standard therapy and demonstrated its non-inferiority in treating pulmonary embolism.
A pre-procedure bleeding risk score can predict greater risk and higher costs for patients undergoing percutaneous coronary intervention (PCI) procedures. The study identified that high-risk patients experience increased rates of complications, longer hospital stays, and higher total costs.
A new class of platelet blockers has been shown to reduce the risk of recurrent cardiovascular events in patients with known atherosclerosis.

A case report reveals the devastating consequences of dabigatran-induced brain hemorrhage, emphasizing the importance of rapid assessment and intervention after minor head trauma in patients taking anticoagulant medications. The study's findings underscore the need for medical providers to be aware of this high-risk complication.
A simplified approach to preventing post-birth bleeding appears safe and effective, reducing the risk of severe bleeding by almost half. The study's findings suggest that a uterotonic agent like oxytocin can be used to prevent PPH, making it accessible to more women in areas with limited medical staff.
Researchers say anti-clotting effect of heparin is well established but its impact on cancer patients remains unclear. The SAVE-ONCO study found semuloparin reduced thromboembolism incidence but had no significant effect on major bleeding and death.
In a large head-to-head study, warfarin and aspirin showed similar efficacy in reducing mortality and stroke risk in patients with heart failure and normal heart rhythms. Warfarin was found to be more effective in preventing strokes after four years of treatment.
A new study by the American Heart Association found that combining clopidogrel with aspirin for stroke prevention in patients with subcortical strokes may increase the risk of bleeding and death. The trial involved over 3,000 patients and showed that there was no difference in stroke recurrence between treatment arms.
Researchers developed a minimally invasive treatment to dissolve brain blood clots, increasing patients' independence by 10-15% six months post-procedure. The technique reduces the need for craniotomy surgery and is as safe as supportive therapy.
Researchers discovered that rivaroxaban, a new anti-clotting drug, is less likely to cause brain bleeding in patients with atrial fibrillation (AF) who are at high risk of stroke. The study found five risk factors that increase the likelihood of AF patients experiencing intracranial bleeding.
Upper GI bleeding is common and serious in dialysis patients, with rates 10 times higher than in the general population. The condition can lead to early deaths and substantial negative effects on kidney function.
Researchers found that a new drug called cangrelor helped patients maintain platelet inhibition at higher rates than placebo before undergoing cardiac surgery. This was significant because premature discontinuation of antiplatelet therapy prior to surgery can lead to increased ischemic complications.
A new treatment for hemophilia A has shown significant reductions in bleeding events and infusion frequency, particularly in children and adolescents. The study suggests that prophylaxis is the optimal treatment for patients with severe hemophilia, improving quality of life.
