Elucidating interfacial failure of cervical restorations using damage mechanics: A finite element analysis.

Background/purpose: Although clinical studies have suggested a link between non-axial forces and reduced longevity of cervical restorations, the underlying mechanisms require further numerical investigation. This in-silico study employed a cohesive zone model (CZM) to investigate interfacial damage in a cervical restoration subjected to different load directions.

Materials And Methods: A plane strain model of a maxillary premolar was established, with a wedge-shaped buccal cervical restoration.

Clinical characteristics and esophageal motility in patients with gastric cardia submucosal tumors and associated changes after endoscopic resection.

Background: This study aimed to investigate the clinical characteristics and esophageal motility of patients with gastric cardia submucosal tumors (SMTs) and the associated changes after endoscopic resection based on high-resolution impedance manometry (HRIM).

Methods: From our electronic database, we identified patients who underwent pre-operative evaluation of gastric cardia SMTs between 2015 and 2023. All patients completed standardized symptom questionnaires and underwent endoscopic ultrasonography and HRIM.

Using a deep learning model to predict postoperative visual outcomes of idiopathic epiretinal membrane surgery.

Purpose: This study assessed the performance of various deep learning models in predicting the postoperative outcomes of idiopathic epiretinal membrane (ERM) surgery based on preoperative optical coherence tomography (OCT) images.

Design: Validation of algorithms to predict the outcomes of ERM surgery based on OCT data.

Methods: Internal training and validation were performed using 1,392 OCT images from 696 eyes.

The Optimal Dosage and Duration of Omega-3 Polyunsaturated Fatty Acid Supplementation in Heart Failure Management: Evidence from a Network Meta-Analysis.

Heart failure is a progressive condition associated with a high mortality rate. Despite advancements in treatment, many patients continue to experience less-than-ideal outcomes. Omega-3 polyunsaturated fatty acids (n-3 PUFAs) have been studied as a potential supplementary therapy for heart failure, but the optimal dosage and duration of supplementation remain unclear.

Impact of Tafamidis on [Tc]Tc-pyrophosphate Scintigraphy in Ala97Ser Hereditary Transthyretin amyloid cardiomyopathy: significant initial reduction with stable Long-Term effects.

Objective: Tafamidis has shown potential in slowing disease progression in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). This study aimed to evaluate serial changes on [Tc]Tc-pyrophosphate (PYP) scintigraphy during tafamidis treatment for hereditary ATTR-CM.

Methods: We retrospectively analyzed a prospectively collected cohort of Ala97Ser (A97S) hereditary ATTR-CM patients treated with tafamidis (61 mg/day) and a control group comprising A97S hereditary ATTR-CM patients who had not received disease-modifying medications.
