Preliminary Evaluation of Nontransecting Anastomotic Urethroplasty for Pelvic Fracture Urethral Injury: Insights From a Comparison With Excision and Primary Anastomosis.

Objectives: To evaluate the feasibility and surgical and patient-reported outcomes of nontransecting anastomotic urethroplasty (NTAU) for male patients with pelvic fracture urethral injury (PFUI) compared with excision and primary anastomosis (EPA), the current mainstay surgical approach.

Methods: This retrospective study analyzed 233 male PFUI patients treated with EPA (n = 223) or NTAU (n = 10) from 2008 to 2024 by a single surgeon (AH). NTAU involves preserving urethral continuity and maintaining bilateral bulbar artery integrity while excising scar tissue and achieving tension-free urethral anastomosis.

Respiratory Muscle Strength as a Predictor of Exacerbations in Patients With Chronic Obstructive Pulmonary Disease.

Background And Objective: Chronic obstructive pulmonary disease (COPD) is closely related to skeletal muscle dysfunction, and the evaluation of respiratory muscle function has recently been recommended. We aimed to investigate the effects of respiratory muscle dysfunction on clinical outcomes.

Methods: We retrospectively reviewed the medical records of patients with COPD whose respiratory muscle strength was measured between June 2015 and December 2021.

Abundant ammonia and nitrogen-rich soluble organic matter in samples from asteroid (101955) Bennu.

Organic matter in meteorites reveals clues about early Solar System chemistry and the origin of molecules important to life, but terrestrial exposure complicates interpretation. Samples returned from the B-type asteroid Bennu by the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer mission enabled us to study pristine carbonaceous astromaterial without uncontrolled exposure to Earth's biosphere. Here we show that Bennu samples are volatile rich, with more carbon, nitrogen and ammonia than samples from asteroid Ryugu and most meteorites.

Determination of appropriate energy threshold range for accurate estimation of effective atomic number considering statistical uncertainty in photon-counting techniques.

Purpose: The energy threshold is an important parameter for precise material identification employing photon-counting techniques. However, in such applications, the appropriate energy threshold has not been clarified. Therefore, we aimed to determine the appropriate energy threshold range for precise material identification, focusing on effective atomic number (Z) values as an index.

Genetic analysis for diagnosing local recurrence of sigmoid colon cancer mimicking a small intestinal tumor: a case report.

Background: With recent advances in genetics research, genetic analysis is increasingly being used in clinical practice. We report a case in which genetic analysis aided in diagnosing a local recurrence of sigmoid colon cancer, initially suspected to be a primary neoplasm of the small intestine.

Case Presentation: A 61-year-old male underwent laparoscopic sigmoidectomy for stage IIIB sigmoid colon cancer, followed by 8 cycles of CAPOX adjuvant chemotherapy, one and a half years prior.
