Phosphorus-Nitrogen Compounds: Part 76. Design and Syntheses of Dispiro- and Trispiro(N/N)cyclotriphosphazenes: Conformational and Structural Analyses, Chirality, Electrochemical, Dye-Sensitized Solar Cells, and Bioactivity Studies.

The reactions of monospirocyclotriphosphazenes ( and ) with -methyl-1,3-diaminopropane gave unsymmetrical -( and ) and -( and ) dispirocyclotriphosphazenes. Trans-cis-trans () ( and ), cis-cis-cis () ( and ), trans-trans-cis () ( and ), and cis-trans-trans () () trispirocyclotriphosphazenes were obtained from the reactions of and and and with -methyl-1,3-diaminopropane. -Dispirocyclotriphosphazenes ( and ) exist as "pseudomesoracemates", while -dispirocyclotriphosphazenes ( and ) are in "racemates".

Rigicon ContiClassic and ContiReflex artificial urinary sphincter devices.

The modern AMS 800 artificial urinary sphincter (AUS) is often considered the standard of care for the treatment of moderate to severe stress urinary incontinence in male patients. Nonetheless, the AMS 800 device has several inherent limitations, and these factors can potentially impact its clinical utility and impede excellent clinical outcomes. The new Rigicon AUS devices such as ContiClassic and ContiReflex urinary sphincters are designed to overcome some of the existing issues pertaining to the AMS 800 device.

Renal Access in Pediatric Supine Miniaturized Percutaneous Nephrolithotomy: Comparative Evaluation of Ultrasound-Fluoroscopy Combined and Biplanar (0°-90°) Fluoroscopic Techniques.

Ultrasound (US)-guided puncture has the benefits of avoiding radiation and limiting the risk of visceral injury. We aimed to evaluate the results of two different renal access techniques during pediatric supine mini percutaneous nephrolithotomy (smPCNL) in a comparative manner. Data obtained from pediatric patients undergoing smPCNL by single surgeon between September 2021 and 2023 were reviewed retrospectively.

Pandemic of the century: COVID-19 in inflammatory rheumatic diseases of a national cohort with 3,532 patients.

Objectives: This study aimed to assess the clinical outcomes and risk factors for severe coronavirus disease 2019 (COVID-19) in patients with inflammatory rheumatic disease (IRD) of a national cohort.

Patients And Methods: The multicenter cross-sectional study was carried out between July 15, 2020, and February 28, 2021. Data collection was provided from a national network database system, and 3,532 IRD patients (2,359 males, 1,173 females; mean age: 48.
