Modern speckle tracking allows the assessment of atrial strain in the clinic. The approach is new, lacks standardization and the user might encounter several problems in its routine use. This article provides guidance on how avoid pitfalls and how to perform reliable and reproducible atrial strain measurements according to current recommendations.Objective Prediction of disease phenotypes and their outcomes is a difficult task. In practice, patients routinely seek second opinions from multiple clinical experts for complex disease diagnosis. Our objective is to mimic such a practice of seeking second opinions by training 2 agents with different focuses the primary agent studies the most recent visit of the patient to learn the current health status, and then the second-opinion agent considers the entire patient history to obtain a more global view. Materials and methods Our approach Dr. Agent augments recurrent neural networks with 2 policy gradient agents. Moreover, Dr. Agent is customized with various patient demographics information and learns a dynamic skip connection to focus on the relevant information over time. We trained Dr. Agent to perform 4 clinical prediction tasks on the publicly available MIMIC-III (Medical Information Mart for Intensive Care) database (1) in-hospital mortality prediction, (2) acute care phenotype classification, (3) physiologic decompensation prediction, and (4) forecasting length of stay. We compared the performance of Dr. Agent against 4 baseline clinical predictive models. Results Dr. Agent outperforms baseline clinical prediction models across all 4 tasks in terms of all metrics. Compared with the best baseline model, Dr. Agent achieves up to 15% higher area under the precision-recall curve on different tasks. Conclusions Dr. Agent can comprehensively model the long-term dependencies of patients' health status while considering patients' demographics using 2 agents, and therefore achieves better prediction performance on different clinical prediction tasks.Polymerase proofreading-associated polyposis, caused by germline variants in the exonuclease domains of POLD1 and POLE, is a dominantly inherited rare condition characterized by oligo-adenomatous polyposis and increased risk of colorectal cancer, endometrial cancer and brain tumours. We report the first Japanese case of polymerase proofreading-associated polyposis carrying a POLD1 variant. The proband was a Japanese woman who had undergone resections of early colorectal carcinomas repeatedly and a hysterectomy with bilateral oophorectomy for endometrial cancer, all of which were diagnosed within 2 years after the first colectomy at 49 year old. Colonoscopic examinations demonstrated at least 14 non-cancerous polypoid lesions, some of which were histologically confirmed to be adenoma. Selleckchem Cepharanthine Multigene panel sequencing identified a missense variant in POLD1 (c.1433G>A). Although her relatives did not undergo genetic testing, her father and paternal grandfather died of brain tumours at 53 and ~30 years of age, respectively.Canonical meiosis is characterized by two sequential rounds of nuclear divisions following one round of DNA replication-reductional segregation of homologous chromosomes during the first division and equational segregation of sister chromatids during the second division. Meiosis in an inverted order of two nuclear divisions-inverted meiosis has been observed in several species with holocentromeres as an adaptive strategy to overcome the obstacle in executing a canonical meiosis due to the holocentric chromosome structure. Recent findings of co-existence of inverted and canonical meiosis in two monocentric organisms, human and fission yeast, suggested that inverted meiosis could be common and also lead to the puzzle regarding the mechanistic feasibility for executing two meiosis programs simultaneously. Here, we discuss apparent conflicts for concurrent canonical meiosis and inverted meiosis. Furthe
