AI Article Synopsis

  • The study examines the link between contrast-induced nephropathy (CIN) and post-transcatheter aortic valve implantation (TAVI) mortality, highlighting the importance of predicting CIN risks.
  • The modified Mehran score, which is calculated before the procedure, was found to be a significant predictor of CIN development compared to the original score.
  • Among 171 TAVI patients, 25.7% experienced CIN, with high modified Mehran scores and elevated preoperative C-reactive protein levels identified as independent risk factors.

Article Abstract

Considering the increasing use of the transcatheter aortic valve implantation (TAVI) procedure, the relationship of contrast-induced nephropathy (CIN) with post-TAVI mortality has become important. The Mehran score was developed to detect the risk of CIN development after cardiac intervention. We aimed to compare the role of the modified Mehran score, which can be calculated pre-procedure, in predicting CIN development and compare it with the original Mehran score. We retrospectively collected data from TAVI procedures at our institution between December 2016 and June 2021; of 171 patients, 44 (25.7%) had CIN. We found no association between contrast media volume and CIN (387 ± 120 418 ± 139 mL, = .303). High and very high modified Mehran score and preoperative C-reactive protein (CRP) level were independent risk factors for CIN development after TAVI procedure. The area under curve (AUC) was .686 with 95% CI: .591-.780 and < .001, and also, with a cut-off point of >7.5 points, there was 79.5% sensitivity and 63.0% specificity; otherwise, with a cut-off point of >9.5 points, there was 54.5% sensitivity and 71.7% specificity, for the modified Mehran score. The modified Mehran score comes into prominence compared with the original Mehran score since it can be calculated pre-procedure.

Rectangular Repetitive Transcranial Magnetic Monophasic vs Biphasic Stimulation for Major Depressive Disorder: A Randomized Controlled Pilot Trial.

Neuromodulation

January 2025

Department of Psychiatry and Behavioral Sciences, Division of Child and Adolescent Psychiatry, Weill Institute for Neurosciences, University of California San Francisco, San Francisco, CA, USA.

Objectives: Biphasic sinusoidal repetitive transcranial magnetic stimulation (rTMS) is a noninvasive brain stimulation treatment that has been approved by the US Food and Drug Administration for treatment-resistant depression (TRD). Recent advances suggest that standard rTMS may be improved by altering the pulse shape; however, there is a paucity of research investigating pulse shape, owing primarily to the technologic limitations of currently available devices. This pilot study examined the feasibility, tolerability, and preliminary efficacy of biphasic and monophasic rectangular rTMS for TRD.

Recent Advances in the Treatment of Coronary In-Stent Restenosis.

Rev Cardiovasc Med

December 2024

Department of Cardiology, Bern University Hospital, Inselspital, CH-3010 Bern, Switzerland.

In-stent restenosis (ISR) remains the predominant cause of stent failure and the most common indication for repeat revascularization. Despite technological advances in stent design, ISR continues to pose significant challenges, contributing to increased morbidity and mortality among patients undergoing percutaneous coronary interventions. In the last decade, intravascular imaging has emerged as an important method for identifying the mechanisms behind ISR and guiding its treatment.

Background And Objectives: Randomized clinical trials have shown that sub-lobar resection for clinical stage (cStage) IA non-small cell lung cancer (NSCLC) is non-inferior to lobar resection. We evaluated traditional and conditional survival differences between lobectomy, wedge resection, and segmentectomy in patients with cStage IA NSCLC.

Methods: The National Cancer Database (2004-2019) was queried for patients with cStage IA (≤ 2 cm) NSCLC who underwent upfront lobectomy, segmentectomy, or wedge resection.

Objective: Contrast-induced nephropathy (CIN) is the third most common cause of hospital-acquired acute renal failure. The increased use of contrast material in diagnostic and interventional cardiac catheterization procedures has made CIN a frequently encountered problem in clinical cardiology practice. Our study aims to understand the role of inflammatory biomarkers in patients developing CIN and to evaluate the relationship of inflammation with the Mehran Score (MRS) and SYNTAX (SYNERGY Between Percutaneous Coronary Intervention with TAXUS and Cardiac Surgery) Score (SS).

The association between non- and pro-healthy diet indices and the risk of colorectal cancer: a case-control study.

BMC Gastroenterol

November 2024

Department of Community Nutrition, Faculty of Nutrition and Food Technology, National Nutrition and Food Technology Research Institute, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background: The Non-Healthy Diet Index (NHDI) and the Pro-Healthy Diet Index (PHDI) are two novel indices that evaluate the healthiness of a diet based on the consumption of several food groups. This study aimed to evaluate the association between adherence to the PHDI and NHDI and colorectal cancer (CRC) risk in the Iranian population.

Methods: The current study was conducted as a hospital-based research using a case (n = 71)- matched-controls (n = 142) design in Tehran, Iran.
