Real-world application of CCTA with CT-FFR for coronary assessment pre-TAVI: the CT2TAVI study.

This study aims to evaluate the implementation of concomitant CAD assessment on pre-TAVI (transcatheter aortic valve implantation) planning CTA (CT angiography) aided by CT-FFR (CT-fractional flow reserve) [The CT2TAVI protocol] and investigates the incremental value of CT-FFR to coronary CT angiography (CCTA) alone in the evaluation of patients undergoing CT2TAVI. This is a prospective observational real-world cohort study at an academic health system on consecutive patients who underwent CTA for TAVI planning from 1/2021 to 6/2022. This represented a transition period in our health system, from not formally reporting CAD on pre-TAVI planning CTA (Group A) to routinely reporting CAD on pre-TAVI CTA (Group B; CT2TAVI protocol).

Indoor air quality and human health risk assessment in selected high-altitude villages of Gilgit-Baltistan, Pakistan.

This research marks the inaugural endeavor in Gilgit-Baltistan (GB) to identify the primary sources of household energy and indoor air pollutants (IAPs) during the winter and additionally, to evaluate the health impacts associated with IAPs within specific high-altitude communities in Gilgit-Baltistan, Pakistan. Using the convenience sampling method, 20 households were continuously monitored to assess IAPs based on standards time-weighted average. The study found that 90% of the population relied primarily on animal dung as their main energy source, with wood, agricultural residues, electricity, and gas as other sources.

The impact of indocyanine green fluorescence angiography (ICG-FA) on anastomotic leak rates and postoperative outcomes in colorectal anastomoses: a systematic review.

Background: Anastomotic leak (AL) is a major complication in colorectal surgery, significantly contributing to perioperative morbidity and mortality. Among strategies to prevent AL, Indocyanine Green Fluorescence Angiography (ICG-FA) has emerged as a promising method for assessing bowel perfusion intraoperatively. This systematic review evaluates the impact of ICG-FA on AL rates and other postoperative outcomes following colorectal anastomoses.

Potential antihyperlipidemic effects of myrcenol and curzerene in high-fat fed rats.

The study evaluated the anti-hyperlipidemic effects of myrcenol and curzerene on a high fat diet induced hyperlipidemia rat model. Thirty male albino rats were fed on a high-fat diet for four months. The HFD-induced hyperperlipidemia rats were treated with rosuvastatin (10 mg/kg), curzerene (130 mg/kg) and myrcenol (100 mg/kg) for four weeks.

Superconductivity in ordered Li-Al-B compounds.

Using first principles calculations, we show that [Formula: see text] materials have strong electron-phonon coupling, with many having a superconducting critical temperature ([Formula: see text]) that exceeds that of the more familiar [Formula: see text] at ambient pressure. In particular, we find that [Formula: see text] is the most stable member of the family, with [Formula: see text] whilst the peak [Formula: see text] is with [Formula: see text] which has [Formula: see text]. Our results reveal that these materials are both thermodynamically and dynamically stable, with strong electron-phonon coupling, indicating significant potential for practical superconducting applications.
