Background: Patients are increasingly turning to generative artificial intelligence to answer medical queries.

Computed tomography for the detection of myocardial hypoperfusion in acute myocardial infarction and the associated CT-to-catheter time.

Emergency computed tomography (CT) often does not allow for comprehensive coronary artery assessment. However, CT may reveal pathological myocardial hypoperfusion suggestive of acute myocardial infarction (AMI), especially in patients presenting with a different diagnostic hypothesis. CT hypoperfusion is known to be associated with myocardial infarction, however the diagnostic value of CT hypoperfusion for the detection of AMI is still not well evaluated.

Single bypass fixation for the treatment of lumbar spondylolisthesis: Anatomical insights and technical note.

Background: Lumbar spondylolisthesis usually requires surgical management for the stabilization of the spine and to relieve patients of their symptoms. This study aims to provide anatomical insights and evaluate the efficacy of single bypass fixation in the surgical treatment of lumbar spondylolisthesis. This technique aims to stabilize the spine with minimal manipulation of the slipped vertebra, thereby reducing potential complications and improving clinical outcomes.

Utilizing environment-friendly eugenol as a diluent with trioctylamine for the reactive extraction of aqueous levulinic acid.

This paper focuses on the reactive extraction of levulinic acid (LA) from aqueous solution by reactive extraction. This goal is achieved using eugenol, a green alternative in the industry, as a solvent in the liquid-liquid equilibrium (LLE) measurements for the ternary system of LA + Eugenol + HO and quaternary systems of LA + Eugenol/ Methanol (MeOH) + HO + Tri-n-octylamine (TOA) at T = 293.15 K.

Efficient bladder cancer diagnosis using an improved RIME algorithm with Orthogonal Learning.

Bladder cancer (BC) diagnosis presents a critical challenge in biomedical research, necessitating accurate tumor classification from diverse datasets for effective treatment planning. This paper introduces a novel wrapper feature selection (FS) method that leverages a hybrid optimization algorithm combining Orthogonal Learning (OL) with a rime optimization algorithm (RIME), termed mRIME. The mRIME algorithm is designed to avoid local optima, streamline the search process, and select the most relevant features without compromising classifier performance.

Excimer laser coronary angioplasty: a mini-narrative review of clinical outcomes.

Background: Excimer laser coronary angioplasty (ELCA) has evolved as a pivotal element in percutaneous coronary intervention (PCI), significantly influencing procedural efficacy and safety. This mini-narrative review explores ELCA's applications, focusing on its efficacy and clinical outcomes. BODY: A search of major databases identified studies from ELCA's inception.

Renal Solitary Fibrous Tumor With Müllerian Cysts: A Novel Differential Diagnosis for Biphasic Renal Neoplasms.

Solitary fibrous tumor is an uncommon mesenchymal neoplasm, initially described in the pleura and infrequently found in the kidney. It is characterized by haphazardly arranged spindle cells, staghorn vasculature, coexpression of CD34 and signal transducer and activator of transcription 6 (STAT6), and a NAB2::STAT6 gene fusion. We report a 64-year-old woman who presented with a 2.

High Mobility Group Box 1 and Cardiovascular Diseases: Study of Act and Connect.

Cardiovascular disease is the deadly disease that can result in sudden death, and inflammation plays an important role in its onset and progression. High mobility group box 1 (HMGB1) is a nuclear protein that regulates transcription, DNA replication, repair, and nucleosome assembly. HMGB1 is released passively by necrotic tissues and actively secreted by stressed cells.

Evaluating Lingual Nerve Repair Outcomes: A Systematic Review.

Purpose: The lingual nerve (LN) is susceptible to injury during oral and maxillofacial procedures, leading to neurosensory deficits. Advances in microsurgical techniques necessitate a comprehensive review of overall effectiveness and influencing factors.

Methods: A systematic review was performed via Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify studies.

Transcatheter aortic valve replacement in patients with severe aortic valve stenosis and concomitant mitral valve regurgitation - 5 years follow-up.

Objectives: To investigate the change in severity of mitral regurgitation (MR) after transcatheter aortic valve replacement (TAVR) and its effect on 5-year mortality.

Background: There is inconsistency in literature on pre-existing MR influencing long-term survival in patients who undergo TAVR.

Methods: Patients who underwent TAVR at the University Hospital Schleswig-Holstein (USKH) Campus Kiel between March 2009 and February 2018 have been enrolled.

Tricuspid Regurgitation and TAVR: Outcomes, Risk Factors and Biomarkers.

. The significance of concomitant tricuspid regurgitation (TR) in the context of transcatheter aortic valve replacement (TAVR) remains unclear. This study aimed to analyze the severity of TR before and after TAVR with regard to short- and long-term survival and to analyze the influencing factors.

Performance of preferentially expressed antigen in melanoma (PRAME) immunohistochemistry for metastatic melanoma in cytology specimens.

Background: Preferentially expressed antigen in melanoma (PRAME) has been introduced as a new melanoma marker and potential target for immunotherapy. While PRAME immunohistochemistry (IHC) is well documented in surgical pathology, similar data in cytology are limited. Metastatic melanoma is frequently diagnosed via cytology samples in which IHC plays an important role.

Encyclopaedic Review of Glipizide Pre-clinical and Clinical Status.

Glipizide is an oral glucose-lowering medication that is beneficial for the treatment of type 2 diabetes. This study compiles exhaustively all accessible information on glipizide, from preclinical to clinical studies. Glipizide may be used in concert with TRAIL to treat cancer cells; in vitro studies have shown that it suppresses angiogenesis and vasculogenesis while shielding cells from glycation-induced damage.

Trans-Brachial TAVI in a Patient with Aortic Isthmus Stenosis: A Case Report.

Background: TAVI indications expand not only to low-risk patients but also to patients with a more complex anatomy and comorbidities. Transfemoral retrograde access is recognized as the first preferred approach according to the current guidelines. However, this approach is not suitable in up to 10-15% of patients, for whom an alternative non-femoral access route is required.

Assessing the Efficacy of Allogeneic Nerve Grafts in Trigeminal Nerve Repair: A Systematic Review.

Purpose: Our primary objective was to assess the efficacy of allogeneic nerve grafts in inferior alveolar nerve or lingual nerve repair. We hypothesized that using allogeneic nerve grafts would be effective, as evidenced by achieving high rates of functional sensory recovery (FSR). Additionally, we looked if sex, time from injury to repair, etiology of nerve damage, and graft length affected outcomes.

Hydrogen Underground Storage in Silica-Clay Shales: Experimental and Density Functional Theory Investigation.

In the context of reducing the global emissions of greenhouse gases, hydrogen (H) has become an attractive alternative to substitute the current fossil fuels. However, its properties, seasonal fluctuations, and the lack of extended energy stability made it extremely difficult to be economically and safely stored for a long term in recent years. Therefore, this paper investigated the potential of shale gas reservoirs (rich and low clay-rich silica minerals) to store hydrogen upon demand.

Can YouTube Be Considered a Reliable Learning Tool for Urology Trainees Seeking Information on Testicular Exploration?

Introduction YouTube, the world's largest video platform, hosts thousands of educational surgical videos that many trainees rely on to enhance their understanding and proficiency in various surgical procedures. Consequently, a crucial inquiry arises regarding the trustworthiness of these videos as a valuable resource for these trainees. In this article, we address this question by focusing on one of the most frequently performed surgical procedures in the field of urology and assessing the effectiveness of these videos as an educational tool for urology trainees (ST3+: Specialty Training Year 3 and above).
