Materials And Methods: This retrospective multicenter observational study enrolled 983 patients who underwent curative gastrectomy with consecutive AC with S-1 or CAPOX for stage II or III GC at 27 hospitals in Korea between February 2012 and December 2013. We conducted propensity score matching to reduce selection bias.

Feasibility of Dual Living Donor Liver Transplantation From Donors With Complex Portal Vein Variations.

Living donor liver transplantation (LDLT) from donors with complex portal vein anomalies has been considered a challenging procedure because vasculobiliary variations of the donor's liver may lead to significant increases in donor and recipient complications. The use of donors with anatomic variations may be considered under the accurate preoperative planning if a more suitable donor is not available. We report a successful dual LDLT for 2 donors with portal vein anomaly to overcome the small-for-size graft syndrome and secure donor safety.

The orbitofrontal cortex functionally links obesity and white matter hyperintensities.

Many studies have linked dysfunction in cognitive control-related brain regions with obesity and the burden of white matter hyperintensities (WMHs). This study aimed to explore how functional connectivity differences in the brain are associated with WMH burden and degree of obesity using resting-state functional magnetic resonance imaging (fMRI) in 182 participants. Functional connectivity measures were compared among four different groups: (1) low WMH burden, non-obese; (2) low WMH burden, obese; (3) high WMH burden, non-obese; and (4) high WMH burden, obese.

Dynamic Changes in Prognosis with Elapsed Time on Ventilators among Mechanically Ventilated Patients.

Previous outcome studies of mechanical ventilation usually adopted a static timeframe to observe the outcome and reported prognosis from the standpoint of the first ventilator day. However, patients and their families may repeatedly inquire about prognosis over time after the initiation of mechanical ventilation. We aimed to describe dynamic changes in prognosis according to the elapsed time on a ventilator among mechanically ventilated patients.

Comparison of 4-French versus 5-French sheaths for diagnostic coronary angiography via the snuffbox approach.

Background: Although a shorter hemostasis duration would be expected when compared with the conventional radial approach as the diameter of the distal radial artery is smaller than that of the conventional radial artery, the optimal duration of hemostasis in diagnostic coronary angiography (CAG) via the distal radial approach, termed the snuffbox approach, has not been well investigated.

Methods: Data from 171 patients were retrospectively collected (55 and 116 patients in the 4-French [Fr] and 5-Fr sheath groups, respectively). The patients had suspected myocardial ischemia and were undergoing diagnostic CAG via the snuffbox approach at a single center between January 2019 and August 2019.
