Recent years have seen the development and advent of novel combinatorial strategies based on immunotherapy, and immune checkpoint inhibitor (ICI) - based treatment has established itself as a mainstay in the treatment of metastatic urothelial carcinoma (UC). Herein, we aimed to validate the prognostic value of a previously developed score, the Prognostic Immunotherapy Score (PIS), including female sex, Eastern Cooperative Oncology Group Performance Status (ECOG-PS) and liver metastases, in patients treated with pembrolizumab for advanced UC from the ARON-2 dataset. We retrospectively analyzed clinical data from Metastatic UC patients diagnosed at age ≥ 18 years.

Objectives: This in vitro study aimed to evaluate the performance of a deep learning (DL)-based workflow for designing inlays, in terms of time efficiency, contact intensity, and contour quality, by comparing it with human-based workflows. The impact of operator experience was also assessed to examine whether the DL-based workflow could reduce experience-related variability.

Methods: A total of 25 digital scans of maxillary and mandibular arches, including posterior abutments prepared for mesial-occlusal (MO) or distal-occlusal (DO) cavities, were used to design inlays using five different workflows.

Objective: The aim of this retrospective cohort study was to evaluate the relationship between leading follicle size at the time of human chorionic gonadotropin (hCG) trigger and live birth rates in Patient-Oriented Strategies Encompassing Individualised Oocyte Number (POSEIDON) groups 3 and 4 undergoing assisted reproductive technology cycles using a gonadotropin releasing hormone (GnRH) antagonist protocol. The objective was to identify the optimal leading follicle size for maximizing live birth outcomes in this challenging patient population.

Material And Methods: This retrospective cohort study included POSEIDON groups 3 and 4 poor responders aged 20-42 years undergoing intracytoplasmic sperm injection with GnRH antagonist protocol between January 2015 and July 2021.

Objective: This study aimed to evaluate the diagnostic performance of biochemical markers in normocalcemic primary hyperparathyroidism (nPHPT), analyse their temporal variations, and assess their correlation with adenoma localisation and size.

Methods: In this multicenter retrospective study-the largest patient cohort reported in the literature to date (n = 474) we comprehensively profiled normocalcemic patients diagnosed with primary hyperparathyroidism nPHPT was diagnosed based on persistently elevated PTH levels with normal serum calcium after excluding secondary causes such as vitamin D deficiency, renal impairment, and other conditions. This retrospective multicenter study included a large cohort of patients whose biochemical markers-including serum calcium, phosphorus, magnesium, vitamin D, parathyroid hormone (PTH), and glomerular filtration rate (GFR)-were measured at three time points, using standardised laboratory protocols.
