Minimally invasive coronary artery bypass grafting using the skeletonized right gastroepiploic artery.

Objective: To evaluate the clinical outcomes of right gastroepiploic artery use in minimally invasive coronary artery bypass grafting.

Methods: A total of 428 patients who underwent minimally invasive coronary artery bypass grafting from February 2012 to February 2024 were included into this retrospective cohort study. The selection criteria for right gastroepiploic artery use included satisfactory artery size and length, significant stenosis (99% to 100%) of the right coronary artery, and unsuitable ascending aorta for partial clamping.

Detecting Early Signs of Extrapericardial Cardiac Tamponade With ECG.

Cardiac tamponade is a condition with impaired cardiac function by acute fluid accumulation in the pericardium. Extracardiac masses, such as a mediastinal hematoma, can also cause cardiac tamponade. We report a case of impending extrapericardial cardiac tamponade secondary to traumatic sternal fracture with expanding mediastinal hematoma.

Aortic valve thrombosis in nephrotic syndrome: a case report.

We report a rare case of aortic valve thrombosis in a 55-year-old man. He had reduced urine output and generalized edema four days before admission. He felt sick and had chest pain on the day of admission.

Dosimetric effects of small field size, dose grid size, and variable split-arc methods on gamma pass rates in radiation therapy.

This study investigates the influence of calculation accuracy in peripheral low-dose regions on the gamma pass rate (GPR), utilizing the Acuros XB (AXB) algorithm and ArcCHECK™ measurement. The effects of varying small field sizes, dose grid sizes, and split-arc techniques on GPR were analyzed. Various small field sizes were employed.

Lessons learned from contamination with endotoxin originated from the supplement in the cell culture medium.

Introduction: Endotoxin is a typical pyrogen derived from the outer membrane of Gram-negative bacteria. In fabricating cell-based medicinal products, it is necessary to control endotoxin in the process and the products. In the quality control tests of our clinical study, endotoxin concentration in the culture supernatant of autologous oral mucosal epithelial cell sheets exceeded the criterion value.

Risk factors for intraoperative and delayed perforation related with gastric endoscopic submucosal dissection.

Background And Aim: Perforation is one of the most important complications of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). Several studies have examined risk factors for intraoperative and delayed perforations, but most were retrospective analyses with small numbers of patients.

Methods: This study represents a secondary analysis of a Japanese multicenter prospective cohort study.

Excess mortality in COVID-19-affected solid organ transplant recipients across the pandemic.

The excess mortality of coronavirus disease 2019 (COVID-19) solid organ transplant recipients (SOTRs) throughout the pandemic remains unclear. This prospective cohort study based on the Japanese nationwide registry included 1632 SOTRs diagnosed with COVID-19 between February 1, 2020, and July 31, 2022, categorized based on dominant phases of variants of concern (VOCs): Waves 1 to 3 (Beta), 4 (Alpha), 5 (Delta), 6 (Omicron BA.1/BA.

Determining zebrafish dorsal organizer size by a negative feedback loop between canonical/non-canonical Wnts and Tlr4/NFκB.

In vertebrate embryos, the canonical Wnt ligand primes the formation of dorsal organizers that govern dorsal-ventral patterns by secreting BMP antagonists. In contrast, in Drosophila embryos, Toll-like receptor (Tlr)-mediated NFκB activation initiates dorsal-ventral patterning, wherein Wnt-mediated negative feedback regulation of Tlr/NFκB generates a BMP antagonist-secreting signalling centre to control the dorsal-ventral pattern. Although both Wnt and BMP antagonist are conserved among species, the involvement of Tlr/NFκB and feedback regulation in vertebrate organizer formation remains unclear.

Coexistence of Low Muscle Mass and Osteoporosis as a Predictor of Fragility Fractures in Long-Term Kidney Transplant Recipients.

Introduction: Sarcopenia and osteoporosis are highly prevalent among kidney transplant recipients (KTRs). Although osteoporosis is known to increase fracture risk in KTRs, it is unclear whether sarcopenia or osteosarcopenia is associated with this increased risk. Thus, we aimed to investigate the association of the coexistence of low muscle mass (LMM) and osteoporosis with the risk of fracture in long-term KTRs.

WONDER-01: immediate necrosectomy vs. drainage-oriented step-up approach after endoscopic ultrasound-guided drainage of walled-off necrosis-study protocol for a multicentre randomised controlled trial.

Background: With the increasing popularity of endoscopic ultrasound (EUS)-guided transmural interventions, walled-off necrosis (WON) of the pancreas is increasingly managed via non-surgical endoscopic interventions. However, there has been an ongoing debate over the appropriate treatment strategy following the initial EUS-guided drainage. Direct endoscopic necrosectomy (DEN) removes intracavity necrotic tissue, potentially facilitating early resolution of the WON, but may associate with a high rate of adverse events.

Improved paradoxical splitting of the second heart sound after cardiac resynchronization therapy.

The outcome of paradox splitting of the second heart sound (S2) after cardiac resynchronization therapy (CRT) has not been well defined. We present a case of right ventricular pacing induced heart failure with prominent paradox splitting of S2 which markedly improved after upgrading to CRT.

Diffuse alveolar hemorrhage and acute eosinophilic pneumonia: A rare form of amiodarone pulmonary toxicity diagnosed by bronchoalveolar lavage.

Unlabelled: A 56-year-old man presented with fever, cough, and bloody sputum. He had undergone mitral valve replacement with mechanical prosthesis 14 months prior for mitral valve disease. Subsequently, the patient was taking warfarin and amiodarone.

Palliative Radiation Therapy without Chemotherapy for a Patient with Monomorphic Epitheliotropic Intestinal T Cell Lymphoma: A Case Report.

Monomorphic epitheliotropic intestinal T cell lymphoma (MEITL), which used to be known as type 2 enteropathy-associated T cell lymphoma, is a rare lymphoma and is generally treated with chemotherapy. However, the MEITL prognosis is poor, and intestinal lymphoma including MEITL has the risk of bowel perforation not only at presentation but also during chemotherapy. A 67-year-old man was diagnosed with MEITL after presenting in our emergency room with bowel perforation.

Successful Diagnosis by Video-Assisted Thoracoscopic Surgical Lung Biopsy in a Case of Progressive Primary Pulmonary Extranodal Natural Killer/T-cell Lymphoma, Nasal Type: A Case Report.

Malignant pulmonary lymphoma is very rare and the majority of which are B-cell lymphomas. Since primary pulmonary extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKL) is difficult to diagnose and associated with poor prognosis and aggressive course, some cases are diagnosed at the postmortem autopsy. We report a case of a 53-year-old man with primary pulmonary ENKL diagnosed by video-assisted thoracoscopic surgery (VATS) lung biopsy.

Initiating Mobilization Is Not Associated with Symptomatic Cerebral Vasospasm in Patients with Aneurysmal Subarachnoid Hemorrhage: A Retrospective Multicenter Case-control Study.

Objective: The study aim was to investigate the association between initiating mobilization within 7 days after onset and symptomatic cerebral vasospasm (SCV) in patients with aneurysmal subarachnoid hemorrhage (aSAH).

Methods: This was a retrospective multicenter case-control study in Japan. Patients with a diagnosis of aSAH who underwent physical therapy with/without occupational therapy were included and categorized into 2 groups according to the presence or absence of SCV.

Serological and histopathological assessment of galactose-deficient immunoglobulin A1 deposition in kidney allografts: A multicenter prospective observational study.

Background: Recurrent immunoglobulin A (IgA) nephropathy is an important risk factor for kidney allograft loss. However, there is no classification system for IgA deposition in kidney allografts based on serological and histopathological evaluation of galactose-deficient IgA1 (Gd-IgA1). This study aimed to establish a classification system for IgA deposition in kidney allografts based on serological and histological evaluation of Gd-IgA1.
