Micro CT evaluation of marginal discrepancies of endocrown restored molars with different intrapulpal depths and materials of fabrication. (in-vitro study).

Objective: The purpose of this study was to evaluate the effect of different preparation depths (0, 2 and 4 mm) of different restoration designs (classic endocrown design versus overlay design) on marginal adaptation of restorations fabricated of two different restorative materials (lithium disilicate and PEEK).

Materials And Methods: Sixty mandibular natural molars were collected as abutments for the restorations of this study, and grouped in three main groups of different cavity depths (0, 2 and 4). Each group was divided into two subgroups according to material of fabrication to (L) for lithium disilicate (IPS emax CAD, Ivoclar vivadent, Switzarland) and (P) for PEEK (Bio-hpp, Bredent, Germany).

Characterizing Circulating microRNA Signatures of Type 2 Diabetes Subtypes.

Type 2 diabetes (T2D) is a heterogeneous disease influenced by both genetic and environmental factors. Recent studies suggest that T2D subtypes may exhibit distinct gene expression profiles. In this study, we aimed to identify T2D cluster-specific miRNA expression signatures for the previously reported five clinical subtypes that characterize the underlying pathophysiology of long-standing T2D: severe insulin-resistant diabetes (SIRD), severe insulin-deficient diabetes (SIDD), mild age-related diabetes (MARD), mild obesity-related diabetes (MOD), and mild early-onset diabetes (MEOD).

Impact of Glaucoma Surgery on Corneal Graft Survival After Keratoplasty: A Systematic Review and Meta-Analysis.

Precis: Glaucoma surgery impacts corneal graft survival differently by procedure type, with GDDs being most effective at reducing intraocular pressure. However, graft survival rates are comparable across trabeculectomy, CPC, and GDDs. Trabeculectomy improves visual acuity best but often requires additional interventions.

Which is easier for beginners: supine or prone position percutaneous nephrolithotomy? Assessment of the learning curve in novice urologists through a randomized clinical trial.

Background: Percutaneous nephrolithotomy (PCNL) could be performed in both prone and supine positions. Each position has its own advantages and disadvantages. "Learning curve" is a graph that represents progress of a skill against the time needed to master the technique.

Survival benefit of cancer-directed surgery and the role of adjuvant therapy in malignant major salivary gland cancers: a propensity score matched retrospective analysis.

Background: The primary objective of this study was to assess the benefit of cancer-directed surgery (CDS) on both overall survival (OS) and cancer-specific survival (CSS) of patients with malignant major salivary gland cancers (MMSGCs). The secondary objective was to explore the benefits of adjuvant therapy on the survival outcomes of these patients.

Methods: Patients diagnosed with MMSGC were extracted from the SEER database and subsequently categorized into two cohorts: CDS and non-CDS.
