Clinical and echocardiographic results of the MEMO 4D semi-rigid annuloplasty ring.

Background: Mitral regurgitation is a frequent valvular disease, with an increasing prevalence. We analyzed the short-term outcomes of mitral valve repair procedures conducted in our clinic using a new semirigid annuloplasty ring featuring a gradual saddle shape design.

Methods: We retrospectively analyzed mitral valve repair surgeries performed at our Institution between December 2019 and November 2021 with the MEMO 4D semirigid annuloplasty ring.

A Qualitative Analysis of the Experiences of Young Patients and Caregivers Confronting Pediatric and Adolescent Oncology Diagnosis.

Epidemiological studies show that new cases of young oncology patients are increasing by 400,000 every year. Psychological literature has shown that receiving an oncological diagnosis can cause significant psychological stress and discomfort. However, the experiences of young patients and their caregivers as they confront this challenge are not yet fully understood.

Sutureless and rapid deployment versus sutured aortic valve replacement: a propensity-matched comparison from the Sutureless and Rapid Deployment International Registry.

Objectives: To compare procedural and in-hospital outcomes of patients undergoing sutureless (Perceval, Livanova PLC, London, UK) and rapid deployment (Intuity Elite, Edwards Lifesciences, Irvine, CA, USA) aortic valve replacement (group 1) versus sutured aortic valve replacement (group 2).

Methods: Patients receiving isolated aortic valve replacement between 2014 and 2020 were analysed using data from the Sutureless and Rapid Deployment International Registry. Patients in group 1 and group 2 were propensity-score matched in a 1:1 ratio.

Prone Positioning in Postoperative Cardiac Surgery Patients: A Narrative Review.

Limited data are available on the use of the prone position in cardiac surgery. Concerns in performing this maneuver in open cardiac surgery due to the risk of post-sternotomy wound infections and hemodynamic instability do not seem to be supported by existing evidence. Indeed, available data show that prone positioning may improve gas exchange in cardiac surgery patients as well.

Sutureless Aortic Valve and Pacemaker Rate: From Surgical Tricks to Clinical Outcomes.

Background: Several studies reported high rates of postoperative permanent pacemaker (PPM) implantation, which has been described as the "Achilles' heel" of sutureless aortic valve replacement (AVR).

Methods: From July 2010 to December 2017, 3,158 patients with symptomatic, severe aortic valve stenosis were referred to the Department of Cardiac Surgery (Klinikum Nürnberg - Paraclesus Medical University, Nuremberg, Germany), and 512 received a Perceval sutureless bioprosthesis (LivaNova PLC, London, United Kingdom). Thirty-nine patients who had been discharged with concomitant PPM implantation were reevaluated.

Presepsin as a potential marker for bacterial infection relapse in critical care patients. A preliminary study.

Background: Systemic bacterial infection carries a high risk of mortality in critical care patients. Improvements in diagnostic procedures are required for effective management of sepsis. Recently, the soluble CD14 subtype, or presepsin, has been suggested as a reliable marker of sepsis, and we set out to compare its diagnostic performance with that of procalcitonin (PCT).

Detection, identification and quantification of a new de-fluorinated impurity in casopitant mesylate drug substance during late phase development: an analytical challenge involving a multidisciplinary approach.

During late phase development of the selective NK1 receptor antagonist casopitant mesylate, a de-fluorinated impurity was discovered and quantified by an orthogonal analytical approach, using NMR and LC-MS. A dedicated (19)F NMR method was initially developed for first line identification and semi-quantification of the impurity. Subsequently, a more accurate quantification was achieved by means of a selective normal-phase LC-MS method, which was fully validated.

Quantitation of a de-fluorinated analogue of casopitant mesylate by normal-phase liquid chromatography/mass spectrometry.

The introduction of Quality by Design (QbD) in Drug Development has resulted in a greater emphasis on chemical process understanding, in particular on the origin and fate of impurities. Therefore, the identification and quantitation of low level impurities in new Active Pharmaceutical Ingredients (APIs) play a crucial role in project progression and this has created a greater need for sensitive and selective analytical methodology. Consequently, scientists are constantly challenged to look for new applications of traditional analytical techniques.
