Artificial intelligence-based model for predicting pulmonary arterial hypertension on chest x-ray images.

Background: Pulmonary arterial hypertension is a serious medical condition. However, the condition is often misdiagnosed or a rather long delay occurs from symptom onset to diagnosis, associated with decreased 5-year survival. In this study, we developed and tested a deep-learning algorithm to detect pulmonary arterial hypertension using chest X-ray (CXR) images.

Comparison of the effect of surgical versus transcatheter aortic valve replacement on the development of postoperative acute kidney injury.

Acute kidney injury (AKI) frequently occurs after cardiac surgery. Recently, transcatheter aortic valve implantation (TAVI), a less invasive option for aortic stenosis (AS), has been increasingly performed, particularly in elderly patients. We retrospectively investigated and compared the incidence and risk factors of postoperative AKI in patients who underwent surgical aortic valve replacement (SAVR) and TAVI.

Effect of laparoscopic liver resection on postoperative delirium in elderly patients with hepatocellular carcinoma.

Background: Delirium is a multifactorial and heterogeneous syndrome that is defined as acutely altered consciousness. This retrospective multicenter study evaluated the impact of postoperative delirium after liver resection for hepatocellular carcinoma (HCC) in elderly patients.

Methods: Patients aged ≥75 years, who underwent curative liver resection for HCC at nine university hospitals from April 2010 to December 2017, were evaluated to compare short- and long-term outcomes between patients with and without delirium.

The Prognostic Value of Preoperative Serum Markers and Risk Classification in Patients with Hepatocellular Carcinoma.

Background: Complex hepatocellular carcinoma (HCC) prognostic biomarkers have been reported in various studies. We aimed to establish biomarkers that could predict prognosis, and formulate a simple classification using non-invasive preoperative blood test data.

Methods: We retrospectively identified 305 patients for a discovery cohort who had undergone HCC-related hepatectomy at four Japanese university hospitals between January 1, 2011 and December 31, 2013.

Short- and long-term outcomes of laparoscopic versus open repeat liver resection for hepatocellular carcinoma: A multicenter study.

Objective: This multicenter study aimed to compare the short- and long-term outcomes of laparoscopic (LRLR) versus open repeat liver resection (ORLR) for recurrent hepatocellular carcinoma (HCC) using propensity score matching (PSM). Despite the expanding indications for laparoscopic liver resection, limited data regarding the outcomes of LRLR have previously been reported.

Methods: This study included patients who underwent repeat liver resection for recurrent HCC.
