Effect of Different Luting Methods on the Microtensile Bond Strength of CAD/CAM Resin Blocks.

The widespread implementation of new CAD/CAM materials has led to the necessity of establishing an adequate luting protocol. The aim of this study was to evaluate the microtensile bond strength (μTBS) and the film thickness of different luting methods on CAD/CAM resin blocks. Five Brilliant Crios CAD/CAM blocks (Coltene/Whaledent) were sequentially sectioned into two halves, air abraded with 50 µm aluminum oxide, and luted according to five different cementation protocols: Brilliant EverGlow (BEG), Brilliant EverGlow with ultrasound application (BEG-US), preheated Brilliant EverGlow (BEG-H), Brilliant EverGlow Flow (BEGF), and Duo Cem Trans (DC).

Adaptive optics cone arrangement in hydroxychloroquine users without signs of retinal toxicity based on current screening guidelines: a case-control study.

Purpose: To describe early cone changes detected by adaptive optics (AO) in patients on chronic hydroxychloroquine (HC) treatment with no abnormalities on standard functional or structural retinal tests.

Methods: Case-control study including 36 eyes of 36 female patients. Cases included 18 women on HC for autoimmune disease whose cumulative dose exceeded 1600 g and who demonstrated no evidence of retinal toxicity on visual field (VF), spectral domain optical coherence tomography (SD-OCT), or multifocal electroretinography (mfERG).

Clinical Outcome of Endothelium-Outward Preloaded Descemet Membrane Endothelial Keratoplasty in Long-Term Dextran-Containing Transport Medium Preservation.

Purpose: To analyze the clinical outcome of organ-cultured endothelium-outward preloaded DMEK (pDMEK) using the RAPID cartridge.

Methods: This prospective study included 80 eyes of 80 patients who received a pDMEK. Best-corrected visual acuity (BCVA), endothelial cell count (ECC), and central corneal thickness were measured preoperatively and 4 to 6 weeks, 3 months, 6 months, and 1 year postoperatively.

Obstetric Intensive Care Admissions and Neonatal Outcomes: 15 Years of Experience from a Single Center.

Maternal severe morbidity and mortality are measures for assessing maternal healthcare, and admissions to the intensive care unit (ICU) can be used to study these metrics. Here, we analyze ICU admissions of pregnant or postpartum women in a tertiary hospital. This is a retrospective, single-center, observational cohort study of obstetric intensive care admissions at a Portuguese hospital spanning 15 years.
