Feasibility and Clinical Outcomes of Vasa Vasorum Embolization for Atypical Type 2 or Type 5 Endoleaks after Endovascular Aneurysm Repair.

The purpose of this study is to evaluate the feasibility and clinical outcomes of vasa vasorum embolization for preventing continuous aneurysmal expansion after endovascular aneurysm repair (EVAR). We retrospectively reviewed the medical records of patients who underwent vasa vasorum embolization between August 2018 and May 2022. Vasa vasorum embolization was attempted in cases of continuous aneurysmal expansion after EVAR, where the vasa vasorum was identified through catheter angiography.

Surgical management of a huge mediastinal mature teratoma in a 2-year-old girl: a case report.

Background: Mature teratomas are benign cystic tumors that are most commonly asymptomatic. However, in some cases, mediastinal teratomas rupture the lungs and mediastinum with potentially fatal outcomes. Herein, we report a case of a large mediastinal mature teratoma that expanded to the entire left hemithorax in a child with common cold-like symptoms.

Rising-frequency chirp stimuli effectively enhance the amplitude and shorten the latency of 40-hz auditory steady-state response.

Objective: To evaluate the effects of changes in group delay from a click signal to a chirp signal on the 40-Hz Auditory Steady-State Response (ASSR) using magnetoencephalography (MEG).

Design: In this study, each participant was exposed to 10 chirp signals with gradually varying group delays from the CE chirp to the click at 60 dB nHL. The 40-Hz ASSR was measured using MEG and evaluated for amplitude and latency in the maximum signal channel at the click signal measured in each hemisphere.

Association between preoperative antifungal therapy and postoperative complications in patients with pulmonary aspergilloma: A national database study in Japan.

Postoperative complications of pulmonary resection in patients with pulmonary aspergilloma are common. Preoperative antifungal therapy is a perioperative management strategy to reduce postoperative complications; however, the benefit of the treatment remains controversial. A retrospective cohort study was conducted using data from the Diagnosis Procedure Combination database (July 2010-March 2021), a national inpatient database in Japan.

Spatially resolved gene expression profiling of tumor microenvironment reveals key steps of lung adenocarcinoma development.

The interaction of tumor cells and their microenvironment is thought to be a key factor in tumor development. We present spatial RNA profiles obtained from 30 lung adenocarcinoma patients at the non-invasive and later invasive stages. We use spatial transcriptome sequencing data in conjunction with in situ RNA profiling to conduct higher resolution analyses.
