Researchers at Johns Hopkins Children's Center found that blood transfusions were needed in less than 3% of pediatric non-cardiac surgeries. In many cases, unnecessary testing and supply waste occurred due to precautionary measures. The study suggests that surgeons should assess each patient's specific needs for blood screening instead...
A large European study suggests men with type 1 diabetes have better blood sugar control than women, especially in older age groups. Women tend to have higher HbA1c levels due to lower hemoglobin levels, which could explain the difference.

The researchers identified SAT1 and other markers that were significantly elevated in the blood of both bipolar disorder patients and those who had committed suicide.
A recent study found that diabetic patients taking oral fluoroquinolones have a higher risk of severe blood sugar-related problems compared to those taking other antibiotics. The increased risk was low, but clinicians should consider this when treating diabetic patients with fluoroquinolones, especially moxifloxacin.
A new study found that remote ischaemic preconditioning can reduce heart muscle damage after coronary artery bypass graft surgery. Patients who underwent the procedure had lower troponin I concentrations, indicating less damage, and were less likely to die from any cause or heart attack/stroke one year after surgery.
Researchers found a higher risk of stroke in patients with mild and moderate/severe hypertensive retinopathy. The study suggests retinal imaging could provide additional information on stroke risk in people with high blood pressure.

The study revealed that patients with rheumatoid arthritis were more than twice as likely to develop these clots, with the risk being highest among younger adults.
A study published in the American Heart Association journal Circulation found that a no-smoking law in Colorado casinos resulted in a 20% drop in ambulance calls, largely attributed to the elimination of secondhand smoke. This reduction is thought to be due to both smokers avoiding toxic effects and quitting smoking altogether.
A new study by Kaiser Permanente and Yale University School of Medicine found that severe hypoglycemia affects many patients with poorly controlled type 2 diabetes. Nearly 11% of respondents experienced severe low blood sugar in the prior year, regardless of their blood sugar control level.
