Introduction: Transvenous leads extraction (TLE) of permanently implanted coronary sinus (CS) leads is widely believed to present greater risks than the removal of other leads.
Aim: To assess the safety and efficacy of CS leads extraction based on large research material obtained by one operator performing procedures in two TLE centres.
Material And Methods: We extracted 408 CS leads from 389 patients, and the results were compared to a control group of 2465 patients who underwent non-CS lead TLE procedures.
Results: There were no significant differences in the clinical success rate (97.9% vs. 98.0%) or the major complication rate (2.1% vs. 1.8%) between the CS and control group. CS lead destination (LV/LA pacing) and tip location (CS ostium/mid CS /CS tributaries) influenced the procedural and radiological success rates and procedural complexity but not the complications. CS lead extraction did not affect the necessity for a cardiosurgical intervention or presence of procedure-related death.
Conclusions: TLE of CS leads can be achieved with a high procedural success rate. The major complication rate is not higher than that seen in non-CS lead extraction patients. More than half of CS leads cannot be removed by simple traction and the use of mechanical sheaths may be necessary. The detachment of CS leads from connective tissue scars in the venous and atrial areas up to the CS ostium is generally sufficient for further removal of the lead using simple traction.

Objective: The EU global health priorities focus on ensuring better health and well-being for people throughout their lives as well as on reducing inequalities between countries. The COVID-19 pandemic can be understood as a set of several events that directly or indirectly affected the mental health of people around the world. The aim of this study was to identify the main groupings of co-occurrence of all keywords related to the main keywords "COVID-19" and "mental health" acquired through search in the Scopus database using the VOSviewer tool.

Background: The adoption of diaphragm and lung ultrasound (DLUS) by physiotherapists, physical therapists, and respiratory therapists ("therapists") to examine and assess the diaphragm and lungs continues to grow. The aim of this updated scoping review is to re-explore and re-collate the evidence around the adoption of DLUS by therapists.
Methods: This scoping review followed the PRISMA-ScR guidelines.

Coenzyme Q (CoQ) and closely related compounds with varying isoprenoid tail lengths (CoQ, = 6-9) are biochemical cofactors involved in many physiological processes, playing important roles in cellular respiration and energy production. Liquid chromatography (LC) coupled with single or tandem mass spectrometry (MS) using electrospray (ESI) or atmospheric pressure chemical ionization (APCI) is considered the gold standard for the identification and quantification of CoQ in food and biological samples. However, the characteristic fragmentation exhibited by the CoQ radical anion ([M], / 862.

Background: Proso millet bran protein (PMBP), derived from agricultural by-products, possesses high nutritional value, despite its challenging extraction process. The present study proposes an extraction method for PMBP using ultrasound-assisted cellulase technology (UAE), and optimizes the process parameters. Non-waxy (N-PMBP) and waxy (W-PMBP) PMBPs, extracted through alkaline solubilization and acid precipitation (conventional treatment, CT), served as control groups to assess the impact of UAE on the structure and functionality of PMBP, as well as the distinctions between N-PMBPs and W-PMBPs.
