Transcriptional Profiling of Patients With Fuchs Endothelial Corneal Dystrophy With and Without Trinucleotide Repeat Expansion in TCF4.

Purpose: To investigate transcriptomic differences between patients with Fuchs endothelial corneal dystrophy (FECD) with and without trinucleotide repeat (TNR) expansion in the transcription factor 4 gene, as the genetic basis for patients with FECD lacking TNR expansion remains unclear.

Methods: Bulk RNA sequencing was performed on corneal endothelial cells from 17 subjects: 10 patients with FECD [4 with repeat expansion lengths <50 (RE-) and 6 with expansions of 50 or more (RE+)] and 7 controls. Differential gene expression analysis was conducted using DESeq2.

Sex-Dependent Variations in Gene Expression in Corneal Endothelial Cells Among Healthy Individuals and Patients With Fuchs Endothelial Corneal Dystrophy.

Purpose: Fuchs endothelial corneal dystrophy (FECD) displays a higher incidence in females than in males, yet the underlying mechanism remains unclear. This study aimed to elucidate sex-dependent differential gene expressions in corneal endothelial cells (CECs) from healthy non-FECD individuals and from patients with FECD.

Methods: RNA-Seq data from CECs of non-FECD subjects (3 males, 4 females) and FECD subjects (5 males, 5 females) were analyzed to identify differentially expressed genes (DEGs) between the sexes.

[Infective Endocarditis Diagnosed After Acute Arterial Occlusion of the Lower Extremity:Report of a Case].

A 73-year-old male was admitted to our hospital due to fever and right lower limb pain. Contrast-enhanced computed tomography (CT) revealed occlusion from the right common femoral artery to the right superficial femoral artery and from the left common iliac artery to the left internal and external iliac arteries, leading to a diagnosis of bilateral acute arterial occlusion of the lower extremity. Emergency thrombectomy was performed to improve arterial blood flow.

Key Therapeutic Agents for Thymic Carcinoma in Real-world Clinical Practice.

Background/aim: Thymic carcinoma is a rare cancer with poor prognosis in unresectable cases. Treatment efficacy of carboplatin+paclitaxel (CP), lenvatinib, S-1, and sunitinib remains uncertain, with some patients experiencing increased post-treatment liver metastasis.

Patients And Methods: We performed a retrospective analysis of patients with metastatic thymic carcinoma who received chemotherapy between 2006 and 2023 at the National Cancer Center Hospital.

A Case of Transapical Thoracic Endovascular Repair for Thoracic Aortic Aneurysm with a Complicated Access Route.

Thoracic endovascular aortic repair (TEVAR) for thoracic aortic aneurysms (TAAs) is an alternative treatment option for high-risk patients. While conventionally performed via a transfemoral approach, it is sometimes difficult due to poor access routes. We report the case of a 90-year-old man who was incidentally diagnosed with a descending TAA while undergoing computed tomography for esophageal cancer.
