Manipulating Backbone Planarity of Ester Functionalized Conjugated Polymer Constitutional Isomer Derivatives Blended with Molecular Acceptors for Controlling Photovoltaic Properties.

Exploring both electron donor and acceptor phase components in bulk heterojunction structures has contributed to the advancement of organic photovoltaics (OPV) realizing power conversion efficiencies reaching 20%. Being able to control backbone planarity of the donor polymer, while understanding its effects on the polymer conformation and photophysical properties, fosters the groundwork for further achievements in this realm. In this report, three isomeric PM7 derivatives are designed and synthesized where the benzodithiophene-4,8-dione structure is replaced by a quaterthiophene bridge carrying two ester moieties.

Prevention of medication-related osteonecrosis of the jaw: institutional insights from a retrospective study.

Background: Medication-related osteonecrosis of the jaw (MRONJ) is a serious, debilitating condition of the jaw bones. Dental extraction is the most significant independent risk factor for MRONJ. This interim study aimed to evaluate the demographics, medical data and outcomes of patients at risk for MRONJ who underwent dental extractions in a dedicated MRONJ clinic following a risk reduction protocol at a large public dental clinic in New South Wales Health.

Association of socioeconomic status with clinical characteristics, care quality and outcomes in patients undergoing transcatheter aortic valve implantation.

Background: Socioeconomic status (SES) is an important determinant of healthcare outcomes in many settings, but few studies have evaluated the impact of SES among patients with aortic stenosis (AS). We sought to explore the association between SES and clinical characteristics, care quality and outcomes among patients undergoing transcatheter aortic valve implantation (TAVI) for severe AS.

Methods: Consecutive patients undergoing TAVI for severe AS at three hospitals between August 2008 and February 2023 were prospectively enrolled in a multicentre registry.

Symptoms of Anxiety and Depression in Patients Who Underwent Transcatheter Aortic Valve Implantation: The SAD-TAVI Study.

Symptoms of anxiety and/or depression (SAD) commonly co-exist in severe aortic stenosis. In patients who underwent transcatheter aortic valve implantation (TAVI), these symptoms are associated with increased morbidity and mortality. Despite this, mental health remains under-researched in the TAVI literature.
