A major study published in JAMA led by researchers at Karolinska Institutet suggests that a possible cause of spontaneous brain haemorrhage could be transmitted via blood transfusion. At the same time, it is very unlikely that anyone should suffer a brain haemorrhage after receiving donated blood. A common cause of spontaneous, recurring brain haemorrhages is the vascular disease cerebral amyloid angiopathy (CAA), in which proteins accumulate along the tiny blood vessels of the brain. Several studies have shown that CAA can be transferred from one individual ...

COVID-19 mRNA vaccination protects babies and young children against COVID-19-associated emergency department/urgent care visits, according to a multistate study from the Centers for Disease Control and Prevention’s VISION Network. The study found that children, age five and younger, who received the original COVID-19 vaccine and the updated vaccine were protected against the need for medical care for COVID in an emergency department or urgent care facility. Emergency department/urgent care visits are considered indicators of moderate disease. The small number of hospitalizations for children ages six months to five years old limited the assessment of vaccine ...

Multimorbidity describes the state of having more than one disease. Anthony Webster sought to untangle a puzzle at the heart of multimorbidity: does having had disease make a patient more likely to have another disease, independent of broad risk factors, such as age, smoking status, or weight? Webster applied a Poisson-Binomial distribution with a Weibull model to predict the incidence of 222 common diseases for approximately 500,000 individuals within the UK Biobank cohort, taking into account their age and established risk factors, but ignoring their history of previous disease or pre-existing conditions. Webster then compared the expected number ...

Sepsis, also colloquially referred to as blood poisoning, is a serious condition. Just over 3,000 people die with a diagnosis of sepsis in Norwegian hospitals each year. However, sepsis is not actually poisoning at all. The condition occurs when the immune system overreacts to an infection that can be caused by bacteria, viruses, fungi or parasites. The immune system attacks the organs of the body and the patient develops organ failure. A new study of 300,000 sepsis admissions has found that the condition is more prevalent than previously thought. However, ...
