Purpose: To evaluate the surgical performance of novice surgeons operating on a three-dimensional (3D) heads-up display system compared to those using a traditional microscope (TM).
Methods: Prospective study design in a private practice setting. Twenty novice surgeons with similar experiences in cataract surgery were selected. Each surgeon performed 20 phacoemulsification cataract surgeries: 10 surgeries on the 3D heads-up display microscope, and 10 surgeries using a TM system. Data were collected from a total of 400 patients operated on by 20 surgeons. Outcome measures were recorded and graded according to the International Council of Ophthalmology's Ophthalmology Surgical Competency Assessment Rubric-Phacoemulsification system. The main outcome measure was mean surgical competency scores.
Results: Overall, 400 data points were equally distributed between TM (200) and 3D (200) surgeries. The mean surgical competency scores were 60.19 (11.41) for TM surgeries and 62.99 (11.11) for 3D surgeries. 3D surgeries had significantly higher surgical competency scores than TM surgeries ( P = 0.013). The mean surgical duration for TM and 3D surgeries was 35.98 (6.02) min and 34.31 (7.12) min, respectively. 3D surgeries took significantly less time than TM surgeries ( P = 0.012). The overall mean best corrected visual acuity in the logarithm of the minimum angle of resolution units was 0.27 (0.42); in TM and 3D surgeries, it was 0.28 (0.43) units and 0.26 (0.41) units, respectively.
Conclusion: The 3D heads-up display system enhances stereopsis in cataract surgery, making it a valuable training tool for novice surgeons in phacoemulsification procedures.

Purpose: Carcinoembryonic antigen (CEA) is an important prognostic factor for rectal cancer. This study aims to introduce a novel cutoff point for CEA within the normal range to improve prognosis prediction and enhance patient stratification in rectal cancer patients.
Methods: A total of 316 patients with stages I to III rectal cancer who underwent surgical tumor resection were enrolled.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

Purpose: The delayed or missed diagnosis of secondary hypertension contributes to the poor blood pressure control worldwide. This study aimed to assess the diagnostic approach to primary aldosteronism (PA) and pheochromocytoma (PHEO) among Italian centers associated to European and Italian Societies of Hypertension.
Methods: Between July and December 2023, a 10-items questionnaire was administered to experts from 82 centers of 14 Italian regions and to cardiologists from the ARCA (Associazioni Regionali Cardiologi Ambulatoriali) Piemonte.
