Two-Generation Toxicity Study of the Antioxidant Compound Propyl-Propane Thiosulfonate (PTSO).

Propyl-propane thiosulfonate (PTSO), an antioxidant organosulfur compound present in the genus , has become a potential natural additive for food and feed, as well as a possible biopesticide for pest control in plants. A toxicological assessment is necessary to verify its safety for livestock, consumers, and the environment. As part of the risk assessment of PTSO, this study was designed to explore its potential reproductive toxicity in mice following the OECD 416 guideline.

Identification of in vitro metabolites of an Allium organosulfur compound and environmental toxicity prediction as part of its risk assessment.

Propyl-propane-thiosulfonate (PTSO) is an organosulfur compound found inAllium spp. Due to its antioxidant and antimicrobial activities, PTSO has been proposed for applications in the agri-food sector, such as feed additive. However, its use with commercial purposes depends on its toxicity evaluation.

Analytical Platform for the Study of Metabolic Pathway of Propyl Propane Thiosulfonate (PTSO) from spp.

The present work is focused on the development of an analytical platform to elucidate the metabolic pathway of PTSO from onion, an organosulfur compound well-known for its functional and technological properties and its potential application in animal and human nutrition. This analytical platform consisted of the use of gas chromatography-mass spectrometry (GC-MS) and ultra-high performance liquid chromatography quadrupole with time-of-flight MS (UHPLC-Q-TOF-MS) in order to monitor volatile and non-volatile compounds derived from the PTSO. For the extraction of the compounds of interest, two different sample treatments were developed: liquid-liquid extraction (LLE) and salting-out assisted liquid-liquid extraction (SALLE) for GC-MS and UHPLC-Q-TOF-MS analysis, respectively.

Simultaneous determination of Allium compounds (Propyl propane thiosulfonate and thiosulfinate) in animal feed using UPLC-MS/MS.

Propyl-propane-thiosulfonate (PTSO) and Propyl-propane-thiosulfinate (PTS) are organosulfur compounds used to supplement the diet of livestock because of their beneficial effects on feed palatability, their antibacterial, anti-inflammatory, and antimethanogenic activities. Besides, antibiotic residues in the environment can be reduced by using these natural bioactive compounds. The objective of this study was to optimize the extraction parameters for the analysis of PTSO and PTS in feed matrices by performing a solid-liquid extraction and quantification by Ultra performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS).

Feasibility and cost of a telemedicine-based short-term plan for initial access in general dermatology in Andalusia, Spain.

Background: In developed countries, health care delivery in dermatology is hampered by the low availability of dermatologists.

Objective: To analyze the feasibility of a teledermatology-based action plan to provide initial dermatologic care in areas with low availability of dermatologists.

Methods: A cross-sectional study describing the feasibility and cost of a 12-month action plan based on a store-and-forward teledermatology (TD) connecting primary care centers and a TD center.

Comparison of Transfemoral Versus Transradial Secondary Access in Transcatheter Aortic Valve Replacement.

Background: Transfemoral approach has been commonly used as secondary access in transcatheter aortic valve replacement (TAVR). Scarce data exist on the use and potential clinical benefits of the transradial approach as secondary access during TAVR procedures. The objective of the study is to determine the occurrence of vascular complications (VC) and clinical outcomes according to secondary access (transfemoral versus transradial) in patients undergoing TAVR.

Successful unilateral vasectomy reversal in a lion ().

Background: In 2016, the veterinarian team of Buin Zoo in Chile decided to try to increase the lion population. At that time, the zoo had three lions; two females and one male. The 9-year-old male had been vasectomized 5 years ago at the same institution for birth control.

Late Electrocardiographic Changes in Patients With New-Onset Left Bundle Branch Block Following Transcatheter Aortic Valve Implantation.

This study sought to determine, in patients with new-onset persistent left bundle branch block (NOP-LBBB) after transcatheter aortic valve implantation (TAVI), the incidence and factors associated with (i) LBBB recovery and (ii) permanent pacemaker implantation (PPI) at 1-year follow-up. This was a multicenter study including 153 patients (mean age: 81 ± 5 years, 56% of women) with NOP-LBBB post-TAVI (balloon-expandable valve in 112 patients). Delta PR (ΔPR) and delta QRS (ΔQRS) were defined as the difference in PR and QRS length between baseline and hospital discharge ECG, and the relative ΔPR and ΔQRS as absolute ΔPR and ΔQRS divided by baseline PR and QRS length, respectively.

Scaling Echocardiographic Cardiac Dimensions to Body Size: A Bayesian Analysis in Healthy Men and Women.

Background: Proper scaling of cardiac dimensions is of paramount importance in making correct decisions in clinical cardiology. The usual normalization of cardiac dimensions to overall body size assumes an isometric relationship. We sought to investigate these relationships to obtain the best allometric coefficient (AC) for scaling.

Use and Outcomes of Triple Antithrombotic Therapy with Non-Vitamin K Antagonists in Patients with Atrial Fibrillation Undergoing Percutaneous Coronary Intervention.

Background: Triple antithrombotic therapy (TT) is recommended for patients with nonvalvular atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI). However, there is a lack of comparative data in a real-world clinical setting between non-vitamin K antagonist oral anticoagulants (NOAC) and vitamin K antagonists (VKA). The aim of this study was to compare the safety and efficacy of TT with NOAC or VKA after PCI in patients with AF at 1-year of follow-up.

Arrhythmic Burden as Determined by Ambulatory Continuous Cardiac Monitoring in Patients With New-Onset Persistent Left Bundle Branch Block Following Transcatheter Aortic Valve Replacement: The MARE Study.

Objectives: The authors sought to determine: 1) the global arrhythmic burden; 2) the rate of arrhythmias leading to a treatment change; and 3) the incidence of high-degree atrioventricular block (HAVB) at 12-month follow-up in patients with new-onset persistent left bundle branch block (LBBB) following transcatheter aortic valve replacement (TAVR).

Background: Controversial data exist on the occurrence of significant arrhythmias in patients with LBBB post-TAVR.

Methods: This was a multicenter prospective study including 103 consecutive patients with new-onset persistent LBBB post-TAVR with the balloon-expandable SAPIEN XT/3 valve (n = 53), or the self-expanding CoreValve/Evolut R system (n = 50).

Immediate and Long-Term Results of Drug-Eluting Stents in Mammary Artery Grafts.

Unlabelled: Percutaneous intervention of a coronary graft is the treatment of choice when the graft fails. The objective is to report the long-term results of drug-eluting stents (DES) in mammary artery grafts (MAG). Patients who had been treated with DES for MAG in 27 centers were selected.

Study design for the "effect of METOprolol in CARDioproteCtioN during an acute myocardial InfarCtion" (METOCARD-CNIC): a randomized, controlled parallel-group, observer-blinded clinical trial of early pre-reperfusion metoprolol administration in ST-segment elevation myocardial infarction.

Background: Infarct size predicts post-infarction mortality. Oral β-blockade within 24 hours of a ST-segment elevation acute myocardial infarction (STEMI) is a class-IA indication, however early intravenous (IV) β-blockers initiation is not encouraged. In recent magnetic resonance imaging (MRI)-based experimental studies, the β(1)-blocker metoprolol has been shown to reduce infarct size only when administered before coronary reperfusion.
