Association between ventricular arrhythmia (premature ventricular contractions burden and nonsustained ventricular tachycardia) and cardiovascular events in patients without structural heart disease.

Background: Premature ventricular contractions (PVCs) and nonsustained ventricular tachycardia (NSVT) are common arrhythmias in cardiovascular clinical settings. However, the clinical significance of PVCs and NSVT in the absence of structural heart disease has not yet been fully elucidated. This study aimed to evaluate the association between PVCs, NSVT, and clinical outcomes.

Feasibility and surgical outcomes of simultaneous urethral reconstruction for synchronous urethral strictures.

Objectives: To evaluate the feasibility and surgical outcomes of simultaneous urethral reconstruction for synchronous urethral strictures (SUS) and analyze the surgical techniques employed for different stricture combinations.

Methods: Twenty-two male patients with SUS who underwent urethral reconstruction between February 2018 and July 2023 were retrospectively reviewed. Stricture locations and lengths were evaluated using cystoscopy and urethrography after urethral rest for at least 3 months.

TFE3-rearranged perivascular epithelioid cell tumors of the head and neck with rare fusion partners: clues to the differential diagnosis between benign and malignant tumors.

Background: Perivascular epithelioid cell tumors (PEComas) rarely appear in the head and neck region. This case report describes two transcription factor E3 (TFE3)-rearranged PEComa cases, consisting of one in the orbit and one in the nasal cavity.

Case Presentation: Both cases demonstrated sheet-like or focal nested architecture and comprised epithelioid cells with abundant clear to eosinophilic cytoplasm and vascular stroma.

Impact of aspirin on biochemical recurrence of prostate cancer after robot assisted radical prostatectomy in a multicenter retrospective cohort study.

This study evaluated the impact of aspirin on the biochemical recurrence (BCR) rate following robot-assisted radical prostatectomy (RARP) in patients. A database search identified patients who underwent RARP for pT2-3N0M0 disease at any of 25 centers between 2011 and 2022, categorized into aspirin (n = 350) and control groups (n = 5857). Adjustment by 1:1 propensity score matching (PSM) and Mahalanobis distance matching (MDM) created 350 matched pairs.

Foot trajectory as a key factor for diverse gait patterns in quadruped robot locomotion.

Four-legged robots are becoming increasingly pivotal in navigating challenging environments, such as construction sites and disaster zones. While substantial progress in robotic mobility has been achieved using reinforcement learning techniques, quadruped animals exhibit superior agility by employing fundamentally different strategies. Bio-inspired controllers have been developed to replicate and understand biological locomotion strategies.
