Highly Efficient and Stable CsPbI Perovskite Quantum Dots Light-Emitting Diodes Through Synergistic Effect of Halide-Rich Modulation and Lattice Repair.

Currently, CsPbI quantum dots (QDs) based light-emitting diodes (LEDs) are not well suited for achieving high efficiency and operational stability due to the binary-precursor method and purification process, which often results in the nonstoichiometric ratio of Cs/Pb/I. This imbalance leads to amounts of iodine vacancies, inducing severe non-radiative recombination processes and phase transitions of QDs. Herein, red-emitting CsPbI QDs are reported with excellent optoelectronic properties and stability based on the synergistic effects of halide-rich modulation passivation and lattice repair.

Histopathologic Progression and Metastatic Relapse Outcomes in Small Cell Neuroendocrine Carcinomas of the Urinary Tract.

Introduction: Small cell neuroendocrine carcinoma of the urinary tract (SCNEC-URO) has an inferior prognosis compared to conventional urothelial carcinoma (UC). Here, we evaluate the predictors and patterns of relapse after surgery.

Materials And Methods: We identified a definitive-surgery cohort (n = 224) from an institutional database of patients with cT1-T4NxM0 SCNEC-URO treated in 1985-2021.

The Application of Concept Map Thinking Combined with Kolcaba's Comfort Nursing in the Perioperative Care of Patients Undergoing Nasal Deformity Correction.

By addressing patients' physical, psychological, social, cultural, and environmental comfort needs holistically, Kolcaba's Comfort Theory raises the standard of care and increases patient satisfaction. This study explored the combined application of these nursing models during the perioperative period for patients undergoing nasal deformity correction surgery. 92 patients undergoing nasal deformity correction at the Seventh Affiliated Hospital of Sun Yat-sen University were randomly divided into two groups: the conventional group (46 patients), which received standard perioperative nursing care, and the experimental group (46 patients), which received concept map thinking nursing combined with Kolcaba's comfort nursing intervention during the perioperative period.

Prophylactic fiberoptic bronchoscopy after sleeve lobectomy can reduce the incidence of postoperative pneumonia: a propensity score matching study.

Background: Postoperative pneumonia (POP) predicts poor outcomes after lung surgery, especially for patients undergoing sleeve lobectomy. Fiberoptic bronchoscopy (FOB) is frequently used in the treatment of POP for patients receiving sleeve lobectomy. This study aimed to assess the effect of prophylactic FOB on the incidence of POP in these patients.

Validation of T stage classification strategy for >2 cm ground-glass opacity non-small cell lung cancer: a retrospective cohort study.

Background: The Lung Cancer Staging Program of the International Association for the Study of Lung Cancer (IASLC) has proposed using solid component size, rather than overall tumor size, for T-staging. However, studies focusing on patients with ground-glass opacity (GGO) lesions with a diameter larger than 2 cm are limited. This study aims to validate the T stage classification strategy recommended by IASLC in this specific and less-studied patient group.
