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, ...

The United States is experiencing its highest overall death rates in more than a century, fueled in part by drug overdose mortality. The origins of the current epidemic are due, at least in part, to a 1986 World Health Organization pronouncement that pain treatment is a universal right. As such, cancer pain treatment guidelines were developed, which included the provision of opioids. In 1995, OxyContin was approved for the management of pain, paving the way for widespread prescription of opioids. Researchers ...
