Improved visualization of the inferior tympanic and mastoid canaliculi with photon counting detector CT.

Purpose: To compare the performance of the photon-counting detector (PCD)-CT versus a state-of-the-art energy-integrating detector (EID)-CT to identify segments of the inferior tympanic canaliculus (Jacobsons nerve) and the mastoid canaliculus (Arnolds nerve).

Materials & Methods: Patients were prospectively recruited to undergo temporal bone CT on both EID-CT (Siemens Somatom Force) and PCD-CT (Siemens NAEOTOM Alpha) scanners under an IRB-approved protocol. Three neuroradiologists reviewed cases by consensus comparing the ability to identify the proximal, mid, and distal segments of the inferior tympanic canaliculus/Jacobsons nerve and mastoid canaliculus/Arnolds nerve on each scanner using 5-point Likert scales (with 1 indicating EID is far superior to PCD, 3 indicating they are equivalent, and 5 indicating PCD is far superior to EID).

Association of cardiorespiratory fitness with the incidence and progression trajectory of cardiometabolic multimorbidity.

Objectives: This study examined the relationship of cardiorespiratory fitness (CRF) in the transition from healthy status to first cardiometabolic disease, subsequent cardiometabolic multimorbidity and further to death.

Methods: We used data from the UK Biobank of 47 484 participants without cardiometabolic diseases at baseline. CRF was assessed via a 6 min incremental ramp cycle ergometer test and expressed in metabolic equivalent of tasks (METs, 1 MET=3.

[Study on the association between different obesity metabolic phenotypes and carotid plaque].

To investigate the relationship between different obesity metabolic phenotypes and the incidence of new carotid artery plaque. The present study is a retrospective cohort study, collecting individuals from the Health Management Center of the Second Affiliated Hospital of Dalian Medical University who had two or more cervical vascular color ultrasound examinations and met the inclusion criteria from 2014 to 2022, and collected their baseline clinical data. According to whether the subjects were obese and had metabolic syndrome, they were divided into metabolically healthy non-obese group, metabolically unhealthy non-obese group, metabolically healthy obese group, and metabolically unhealthy obese group.

Validation of a Prediction Model From Quantitative Coronary Angiography to Detect Ischaemic Lesions as Evaluated by Invasive Fractional Flow Reserve.

Aim: Physician visual assessment (PVA) in invasive coronary angiography (ICA) is clinically used to determine stenosis severity and guide coronary intervention. However, PVA provides limited information regarding the haemodynamic significance of stenosis. This prospective study aimed to develop a model combining visual diameter stenosis (DS) and quantitative coronary angiography (QCA)-derived parameters to diagnose ischaemic lesions using invasive fractional flow reserve (FFR) with pharmacologically induced maximal hyperaemia as the gold standard.

Long-Term Outcomes of Laparoscopic Anatomical versus Non-Anatomical Liver Resection for Hepatocellular Carcinoma.

Objective: The objective of this study was to investigate the long-term outcomes between laparoscopic anatomical liver resection (LAR) and laparoscopic non-anatomical liver resection (LNAR) in patients with hepatocellular carcinoma (HCC).

Methods: In this single-center retrospective cohort study, 1773 patients, from January 2009 to December 2017, were assessed for inclusion. After exclusions, 661 patients were included: 304 patients received LAR and 357 patients received LNAR.
