A 50-year-old man was diagnosed with type 1 autoimmune pancreatitis (AIP) following endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and a histopathological examination. After six months of untreated follow-up, the serum IgG4 level decreased, and the diffuse pancreatic enlargement improved; however, a pancreatic head mass became apparent. EUS-FNA of this mass revealed pancreatic ductal adenocarcinoma (PDAC) with IgG4-positive plasma cells.

Both the damaged plant and the neighboring intact plants induce resistance when they receive these volatiles, a phenomenon known as plant-plant communication. However, field observations of this phenomenon are limited.

Although intraoperative TTFM of the graft showed lower mean flow and higher pulsatility index, suggesting inadequate anastomosis, fast Fourier transform (FFT) analysis of TTFM waveforms presented gradual waning of the amplitude, as shown in patent grafts. FFT analysis of the TTFM waveforms is helpful to judge the patency of LITA to LAD, even with competitive flow.

Here, we examined whether volatiles from artificially damaged weeds affect maize growth and reproduction. Seven days after germination, maize seedlings were exposed to volatiles emitted by artificially damaged mugwort ( var.

Methods and results: We retrospectively collected data for 74 in situ left internal thoracic artery (LITA) grafts and 27 saphenous vein grafts (SVGs) to the LAD that were shown to be patent on postoperative angiography. Spearman correlation coefficients were determined between FFRand TTFM parameters of the LITA graft, as follows: maximum flow (Q), -0.
Background: In the daily routine of acute care wards, where priority is given to patients with severe illnesses and those who require urgent care, working with and supporting the decision making of terminally ill patients can be challenging.
Methods: This study aimed to clarify the perceived difficulties of and learning needs among acute care ward nurses providing end-of-life care during the COVID-19 pandemic. In order to perform analyses by years of clinical experience, we conducted semi-structured interviews with both novice and experienced nurses.
Background: Concerns of gastrointestinal (GI) bleeding after cardiac surgery are increasing with increased use of antiplatelets and anticoagulants. We investigated the roles of preoperative screening for fecal occult blood by fecal immunochemical test (FIT) widely used to detect GI bleeding and cancer.
Methods: A retrospective review was done in 1,663 consecutive patients undergoing FIT before cardiac surgery between years 2012 and 2020.
We investigated whether distal anastomosis to the true lumen in open surgical repair of descending aorta for chronic type B aortic dissection improved the long-term outcomes with aortic remodeling. We retrospectively reviewed 71 patients with chronic type B aortic dissection, excluding those with connective tissue disorder, from October 2001 to June 2021. The patients who underwent distal true lumen anastomosis (group T, n = 36) were compared to those with both lumens' anastomosis (group B, n = 35), regarding survival, overall and distal aortic events.

The well-being of foreign early career academics (FECAs) has been the subject of research attention in relation to present demanding academic milieux in general and to those unfamiliar workplace settings in particular. A traditional variable-oriented approach that focuses on mean scores can easily gloss over the diverse nature of the group under study. Our study, conducted in Japan, took a person-oriented approach and identified FECAs' distinct well-being profiles and the associations of their personal attributes with the profiles.

Eighteen collimated uniform dose plans for cubic targets were optimized by the RayStation 9A treatment planning system (TPS), varying scan area, modulation widths, measurement depths, and collimator angles. To test the patient-specific measurements, we also created and verified five clinically realistic PBS plans with the MLC, such as the liver, prostate, base-of-skull, C-shape, and head-and-neck.

Purpose: Thermoreactive nitinol Flexigrip has been developed to ensure better fixation than conventional wire closure. To verify the advantage of Flexigrip over the conventional wiring, we compared early sternal bone healing on computed tomography (CT).
Methods: A prospective cohort study enrolled the first consecutive 80 patients with wiring and the second consecutive 44 patients undergoing Flexigrip sternal closure.
Objectives: Despite advances in surgical techniques and management, surgical site infection (SSI) is still important after cardiovascular surgery. We investigated to determine whether or not preoperative nasopharyngeal cultures (NCx) can predict SSI and its microbial spectrum.
Methods: A retrospective review was done in 1226 consecutive patients undergoing NCx and cardiac and thoracic aortic surgery via median sternotomy who were cared for with the standard SSI bundle between 2013 and 2018.
We report a case of mechanical prosthetic mitral valve thrombosis in a 52-year-old woman with previous diagnosis of dilated cardiomyopathy, who was supported with advanced mechanical circulatory support after urgent mechanical mitral valve replacement (MVR) and tricuspid annuloplasty. Difficult weaning from cardiopulmonary bypass needed support with veno-arterial extracorporeal membranous oxygenation and Impella (Abiomed Inc, Danvers, MA, USA), so-called ECPELLA. Temporary discontinuation of heparin and massive blood transfusion were necessary due to four times of reoperation for bleeding during ECPELLA support.

Objectives: Patients with cardiovascular disease are vulnerable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection. Although SARS-CoV2 vaccination may be effective, its impact on surgical patients is not well studied. We investigated the effects of cardiovascular surgery, especially under cardiopulmonary bypass (CPB), on the antibody titres after SARS-CoV2 vaccination.

A 73-year-old man diagnosed with moderate aortic insufficiency and dilatation of the aortic root and ascending aorta underwent a modified Bentall procedure and hemi-arch aortic replacement. During open distal anastomosis of the ascending aorta, the surgical needle was lost. Because of circulatory arrest, the operation was continued; before closing the chest, radiography and a transesophageal echo were located in the needle in the descending aorta.
