xColorectal cancer (CRC) is one of the leading causes of cancer deaths worldwide. This article reviews the aetiology and risk factors for CRC and focuses on strategies for prevention and early diagnosis. Prevention involves identifying and optimizing modifiable risk factors through public health awareness as well as population screening, for example using detection of occult blood in stool. Endoscopic surveillance in the UK is currently performed on a population basis with the bowel scope programme and faecal immunochemical testing, with colonoscopy reserved for patients known to be at higher risk of developing CRC.

In November 1846, Henry Jacob Bigelow, a Boston surgeon, reported a breakthrough in the search for surgical anesthetics with the first uses of inhaled ether in 1846. This allowed patients to remain sedated during operations ranging from dental extraction to amputation.[8] "A patient has been rendered completely insensible during an amputation of the thigh, regain consciousness after a short interval," Bigelow wrote. "Other severe operations have been performed without the knowledge of the patients."

Patients with interstitial lung disease associated with systemic sclerosis were treated with usual care plus placebo or nintedanib. The annual rate of change in forced vital capacity assessed over a 52-week period was −52.4 ml per year with nintedanib and −93.3 ml per year with placebo. There were no differences in other measures of systemic sclerosis.
