Cancer antigen 153: A risk factor for ocular metastases in patients with breast cancer.

Ocular metastasis (OM) in breast cancer (BC) always predicts poor prognosis. The present study explored differences in tumor markers in patients with BC with and without OM, and attempted to determine risk factors for OM in patients with BC. This study involved 629 patients with BC.

Effects of ultrasound-guided alveolar recruitment manoeuvres compared with sustained inflation or no recruitment manoeuvres on atelectasis in laparoscopic gynaecological surgery as assessed by ultrasonography: a randomized clinical trial.

Background: The majority of patients may experience atelectasis under general anesthesia, and the Trendelenburg position and pneumoperitoneum can aggravate atelectasis during laparoscopic surgery, which promotes postoperative pulmonary complications. Lung recruitment manoeuvres have been proven to reduce perioperative atelectasis, but it remains controversial which method is optimal. Ultrasonic imaging can be conducive to confirming the effect of lung recruitment manoeuvres.
