Acute maternal hyperoxygenation to predict hypoxia and need for emergency intervention in fetuses with transposition of the great arteries: a pilot study.

Background: Newborns with transposition of the great arteries (TGA) are at risk of severe hypoxia from inadequate atrial mixing, closure of the arterial duct and/or pulmonary hypertension (PPHN). Acute maternal hyperoxygenation (AMH) might assist in identifying at-risk fetuses. We report pulmonary vasoreactivity to AMH in TGA fetuses and its relationship to early postnatal hypoxia and requirement for emergency balloon atrial septostomy (e-BAS).

Oxylipin Receptors and Their Role in Inter-Partner Signalling in a Model Cnidarian-Dinoflagellate Symbiosis.

Oxylipin signalling is central in biology, mediating processes such as cellular homeostasis, inflammation and molecular signalling. It may also facilitate inter-partner communication in the cnidarian-dinoflagellate symbiosis, though this aspect remains understudied. In this study, four oxylipin receptors were characterised using immunohistochemistry and immunoblotting in the sea anemone Exaiptasia diaphana ('Aiptasia'): Prostaglandin E2 receptor 2 (EP2) and 4 (EP4), Transient Receptor Potential cation channel A1 (TRPA1) and Glutamate Receptor Ionotropic, Kainate 2 (GRIK2).

Clinical Trial Eligibility and Outcomes in Patients With Metastatic NSCLC Treated Outside of Clinical Trials.

Introduction: There are limited data available regarding patient outcomes in those who would have been ineligible to receive therapy based on the original clinical trial eligibility criteria. We decided to conduct a retrospective study to evaluate outcomes based on clinical trial eligibility in patients with metastatic non-small cell lung cancer (NSCLC).

Methods: A retrospective chart review of all patients with metastatic NSCLC who received first-line systemic therapy at a single academic institution was performed.

Topography of ischemic strokes in cancer-associated non-bacterial thrombotic endocarditis: A single-institution descriptive case series.

Background: Very limited data indicate that patients with stroke from cancer-associated NBTE (Ca-NBTE) exhibit a characteristic pattern of widely distributed ischemic lesions of varying sizes.

Methods: An electronic search of Mayo Clinic records (03/31/2002-06/30/2022) with ensuing manual review of brain magnetic resonance imaging (MRI) was performed to identify topographic characteristics of stroke from Ca-NBTE.

Results: In 112 patients with Ca-NBTE, 92 (82.
