Variability in coronary hemodynamics in response to ergonovine in patients with normal coronary arteries and atypical chest pain [PDF]

, 1983
Because an increase in coronary vascular resistance in response to ergonovine maleate has been suggested as a possible diagnostic aid for variant angina, changes were evaluated in coronary hemodynamics and serial myocardial thallium-201 perfusion scans ...

Visualization of the Coronary Sinus in Cineangiocardiography [PDF]

Circulation, 1955
Reflux opacification of the coronary sinus was observed in 25 of 100 cases examined by cineangiocardiography. Of the 25 coronary sinus "positive" cases, 88 per cent were found to have cardiovascular lesions which are regularly associated with severe hypertension of the right heart chambers.

Updated risk prediction model for pancreaticoduodenectomy using data from the National Clinical Database in Japan

Annals of Gastroenterological Surgery, EarlyView.
The calibration plots of the updated risk models for the endpoints were analyzed in each cohort. The predicted probability of each endpoint matched the observed probability in the development and validation cohorts. Abstract Aim Risk prediction models for mortality, severe postoperative complications, and postoperative pancreatic fistula in patients ...

German guideline diverticular disease/diverticulitis

United European Gastroenterology Journal, Volume 10, Issue 9, Page 923-939, November 2022., 2022
Abstract Diverticulosis and diverticular disease are ranked among the most common gastroenterological diseases and conditions. While for many years diverticulitis was found to be mainly an event occurring in the elder population, more recent work in epidemiology demonstrates increasing frequency in younger subjects.
