A rare complex association of truncus arteriosus with anomalous left coronary artery from the pulmonary artery: A case of rare congenital deformity.

Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital deformity, and its association with truncus arteriosus (TA) has been infrequently described in medical literature. We report a case of a 3-year-old child presenting with failure to thrive and recurrent respiratory infections, who was diagnosed with truncus arteriosus type 1 and an anomalous left coronary artery originating from the pulmonary artery. The embryological basis of both TA and ALCAPA involves disruptions in the normal development of the aorticopulmonary septum and coronary arteries.

Left ventricular pseudoaneurysm as a rare catastrophic complication to surgical repair of mitral valve endocarditis.

Introduction: Left ventricular pseudoaneurysm (LVPA) is rarely described in the medical literature, as a complication of mitral valve repair after infective endocarditis (IE) and only a few cases have been published until now.

Case Presentation: We reported a case of a woman in her forties without past medical history who underwent a successful surgical repair of mycotic pseudoaneurysm at the apex of the left ventricular after two months of mitral mechanical prosthetic valve replacement due to infective endocarditis.

Discussion: Infective endocarditis (IE) remains a rare condition with high associated morbidity and mortality.

NuCLS: A scalable crowdsourcing approach and dataset for nucleus classification and segmentation in breast cancer.

Background: Deep learning enables accurate high-resolution mapping of cells and tissue structures that can serve as the foundation of interpretable machine-learning models for computational pathology. However, generating adequate labels for these structures is a critical barrier, given the time and effort required from pathologists.

Results: This article describes a novel collaborative framework for engaging crowds of medical students and pathologists to produce quality labels for cell nuclei.

Characterization of an Isostructural MOF Series of Imidazolate Frameworks Potsdam by Means of Sorption Experiments with Water Vapor.

Sorption measurements of water vapor on an isoreticular series of Imidazolate Frameworks Potsdam (IFP), based on penta-coordinated metal centers with secondary building units (SBUs) connected by multidentate amido-imidate-imidazolate linkers, have been carried out at 303.15 K. The isotherm shapes were analyzed in order to gain insight into material properties and compared to sorption experiments with nitrogen at 77.

Characteristics, survival and incidence rates and trends of primary cardiac malignancies in the United States.

Background: The available literature on the incidence, management and prognosis of primary malignant cardiac tumors [PMCTs] is limited to single-center studies, prone to small sample size and referral bias. We used data from the Surveillance, Epidemiology, and End Results [SEER]-18 registry (between 2000 and 2014) to investigate the distribution, incidence trends and the survival rates of PMCTs.

Methods: We used SEER*Stat (version 8.
