Incidence of Postoperative Diabetes Mellitus After Roux-en-Y Reconstruction for Gastric Cancer: Retrospective Single-Center Cohort Study.

Background: Sleeve gastrectomy is an effective surgical option for morbid obesity, and it improves glucose homeostasis. In patients with gastric cancer and type 2 diabetes mellitus (DM), gastrectomy, including total gastrectomy, is beneficial for glycemic control.

Objective: This study aims to clarify the effects of gastrectomy and different reconstructive techniques on the incidence of postoperative DM in patients with gastric cancer.

Neuropathies Following an Ultrasound-Guided Axillary Brachial Plexus Block.

Purpose: Ultrasound-guided brachial plexus block (UGBPB) has interscalene, supraclavicular, infraclavicular, and axillary approaches. The axillary block is considered to be the safest and with fewer adverse events compared to the interscalene (eg, phrenic nerve block, spinal cord or vertebral artery puncture) and supraclavicular (eg, pneumothorax). However, with regard to postoperative neurological symptoms (PONS), it is controversial whether its incidence after an axillary block was higher than that after non-axillary approaches".

Optimal COVID-19 testing strategy on limited resources.

The last three years have been spent combating COVID-19, and governments have been seeking optimal solutions to minimize the negative impacts on societies. Although two types of testing have been performed for this-follow-up testing for those who had close contact with infected individuals and mass-testing of those with symptoms-the allocation of resources has been controversial. Mathematical models such as the susceptible, infectious, exposed, recovered, and dead (SEIRD) model have been developed to predict the spread of infection.

Identical wave forms of vena cava and pulmonary artery during pulmonary artery catheter insertion due to kinking: a case report of a rare complication.

Background: We experienced a rare malposition of a pulmonary artery catheter due to kinking in a 63-year-old male who was scheduled for an off-pump coronary artery by-pass graft.

Findings: Given the difficulty to obtain stable pulmonary artery waveform, we discovered that the two waveforms of the distal and proximal ports of the pulmonary artery catheter were completely identical. Subsequent fluoroscopy revealed that because the catheter had formed a kink around the apex of the right ventricle, the distal port faced the proximal port of the catheter.
