Time-resolved or time-correlation measurements using cathodoluminescence (CL) reveal the electronic and optical properties of semiconductors, such as their carrier lifetimes, at the nanoscale. However, halide perovskites, which are promising optoelectronic materials, exhibit significantly different decay dynamics in their CL and photoluminescence (PL). We conducted time-correlation CL measurements of CsPbBr using Hanbury Brown-Twiss interferometry and compared them with time-resolved PL.

We assessed the clinical outcomes of patients with chronic limb-threatening ischemia (CLTI) without revascularization who did and did not undergo repetitive hyperbaric oxygen therapy (HBOT).
Methods: Between April 2002 and March 2017, the records of 58 patients with CLTI (Rutherford classification 4 in 19% and 5 in 81%) were evaluated retrospectively.
Objective: This study aimed to comparatively analyze sociodemographic data and postoperative parameters of patients undergoing bypass and sleeve surgeries in a private hospital in São Luís, MA.
Methods: The study was descriptive, prospective, observational, and comparative, with a quantitative approach between August 2020 and July 2021. We analyzed 74 participants of both genders, aged between 18 and 70 years, with 31 undergoing Roux-en-Y gastric bypass surgery and 43 undergoing sleeve gastrectomy surgery.
A 62-year-old male patient was admitted for close monitoring of anemia (hemoglobin level, 8.2 g/dl). Hemolytic anemia was observed; however, the direct antiglobulin test (DAT) result (standard tube method) was negative.
