Article Abstract

Introduction: This study evaluated the efficacy of a novel Jasminum-based titanium dioxide nano-reinforced calcium hydroxide (Ca(OH)) intracanal medicament in reducing postoperative pain (PP) compared to conventional Ca(OH) in patients with symptomatic apical periodontitis.

Methods: A triple-blind randomized clinical trial, registered at ClinicalTrials.gov (NCT06653608, 10/19/2024) included patients with single-rooted teeth diagnosed with pulp necrosis and symptomatic AP. Patients referred for endodontic treatment fulfilling the inclusion criteria were included. The patients were grouped into nano-reinforced Ca(OH) group (n = 30) and conventional-Ca(OH) (n = 30). Preoperative pain and PP at 4, 24, 48, 72, and 96 hours were recorded using a visual analog scale. Data were analyzed using linear mixed-effects models (R software, version 4.3.2., R Core Team, Vienna, Austria), with significance set at P < .05.

Results: Sixty patients with comparable demographic and clinical characteristics, including preoperative pain scores, were recruited. Both groups exhibited significant pain reduction over 96 hours (P < .001). However, a significant group-time interaction was observed (P < .001), with the nano-reinforced Ca(OH) group reporting consistently lower PP scores and greater reductions in PP compared to the conventional Ca(OH) group at all-time points.

Conclusion: The incorporation of Jasminum-based TiO nanoparticles to Ca(OH) significantly improved the reduction in PP intensity and duration compared to conventional Ca(OH), making it a superior option for PP management.

Transient electronics that can degrade after fulfilling their designed functionalities offer transformative potentials in biomedical implants (eliminating secondary surgeries), ecofriendly consumer electronics (reducing e-waste), and secure systems. However, the development of reliable transient energy supplies remains a critical challenge, thus limiting their widespread implementation. Among various solutions, wireless power supplies via near-field inductive coupling stand out as particularly promising candidates.

Sodium-glucose co-transporter 2 inhibitors (SGLT2i) are a fairly new class of agents for diabetes that have demonstrated significant benefits in glycemic control and cardiovascular outcomes with outpatient use. The aim of this review is to provide an overview of the effect of SGLT2i use on glycemic control and clinical outcomes in the hospital setting.An electronic search of PubMed was conducted to analyze publications that assessed the inpatient use of SGLT2i and included patients with diabetes.

Background: Bone marrow (BM) lesion differentiation remains challenging, and quantitative magnetic resonance imaging (MRI) may enhance accuracy over conventional methods. We evaluated the diagnostic value and inter-reader reliability of Dixon-based signal drop (%drop) and fat fraction percentage (%fat) as adjuncts to existing protocols.

Materials And Methods: In this prospective two-center study, 172 patients with BM signal abnormalities underwent standardized 1.

Background: Distal triceps tendon rupture is related to high complication rates with up to 25% failures. Elbow stiffness is another severe complication, as the traditional approach considers prolonged immobilization to ensure tendon healing. Recently, a dynamic tape was designed, implementing a silicone-infused core for braid shortening and preventing repair elongation during mobilization, thus maintaining constant tissue approximation.

Targeted intraoperative radiotherapy (IORT) delivers a single dose of radiation to a fresh tumour bed immediately after lumpectomy, commonly used to treat early breast cancer (EBC). It is delivered during the same sitting, with improved patient compliance and better sparing of adjacent healthy tissue, compared to conventional adjuvant radiotherapy to the whole breast. The recently published 12-year results (median follow up of 8.
