Shaping Ability of XP-Endo Shaper Files with Extended Use Time and Reciproc Blue 40.06 in Oval Canals: A Micro-Computed Tomography Study in Contralateral Premolars.

Introduction: This study evaluated the shaping ability of the single-file XP-endo Shaper (XP-S) system, employing an extended working time, and the Reciproc Blue #40/.06 (REC) instrument during the preparation of oval-shaped canals.

Methods: Eleven pairs of contralateral premolars with a single canal were divided into two groups (n = 11) according to the canal preparation protocol: XP-S (with an additional 45 seconds of instrumentation) and REC.

Prevalence and risk factors for seizures in adult COVID-19 patients: A meta-analysis.

Seizures may be one of the neurological consequences of COVID-19. The present study aims to review the prevalence of seizures in COVID-19 patients considering sex and geographical origin. A review protocol was submitted to the PROSPERO database (CRD42021281467).

The Use of Rhinomanometry in Mouth Breathing: A Systematic Review of the Literature.

 Mouth breathing generates imbalances in the musculature, in craniofacial morphofunctionality, and in the stomatognathic system. Therefore, it is essential to make a diagnosis of mouth breathing through the quantitative assessment of nasal permeability, which can be performed through rhinomanometry.  To investigate the effectiveness of rhinomanometry in the diagnosis of mouth breathing in pediatric patients through a systematic review of the literature.

Pharmacological interventions for preventing upper gastrointestinal bleeding in people admitted to intensive care units: a network meta-analysis.

Objectives: To assess the efficacy and safety of pharmacological interventions for preventing upper gastrointestinal (GI) bleeding in people admitted to intensive care units (ICUs).

Design And Setting: Systematic review and frequentist network meta-analysis using standard methodological procedures as recommended by Cochrane for screening of records, data extraction and analysis. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the certainty of evidence.

Esophageal Mucosal Impedance Assessment for the Diagnosis of Gastroesophageal Reflux Disease.

Background/aims: Diagnosing gastroesophageal reflux disease (GERD) is sometimes challenging because the performance of available tests is not entirely satisfactory. This study aims to directly measure the esophageal mucosal impedance during upper gastrointestinal endoscopy for the diagnosis of GERD.

Methods: Sixty participants with typical symptoms of GERD underwent high-resolution esophageal manometry, 24-hour multichannel intraluminal impedance-pH monitoring, upper gastrointestinal endoscopy, and mucosal impedance measurement.
