[Establishment and validation of a prediction model for early-stage epithelial ovarian cancer based on LASSO regression].

To establish and validate a prediction model for early-stage epithelial ovarian cancer based on least absolute shrinkage and selection operator (LASSO) regression. A total of 509 cases ovarian mass patients who underwent surgical treatment in Tianjin Medical General Hospital from January 2018 to March 2023 were retrospectively analyzed. The patients were randomly divided into modeling group [=356, (,) for age were 43 (31, 61) years] and internal validation group [=153, age 42 (31, 60) years] by 7∶3 ratio.

Pulmonary embolism and hemorrhage after displacement of angiographic catheter tip to pulmonary artery: A case report and literature review.

Pulmonary embolism and massive hemoptysis caused by intravascular foreign bodies have rarely been reported. We report a case of an end-stage renal disease patient in which the tip of the angiographic catheter fell off into the pulmonary artery during endovascular interventional opening when the patient underwent vascular access occlusion for dialysis. During the operation, the foreign body was displaced repeatedly and finally anchored to the posterior basal segment branch of the right lower pulmonary artery.
