Rationale and Design of the Australasian Registry of Screening ECGs in National Athletes Project.

Background: Cardiac screening of elite athletes is widely recommended by Australasian sporting federations, but data are not structured to be shared. Data are lacking from underrepresented groups to inform ECG interpretation guidelines. The ARENA (Australasian Registry of Screening ECGs in National Athletes) project is a retrospective and prospective, multicenter, longitudinal, observational registry of athlete cardiac screening results and outcomes.

Extracting structured data from organic synthesis procedures using a fine-tuned large language model.

The popularity of data-driven approaches and machine learning (ML) techniques in the field of organic chemistry and its various subfields has increased the value of structured reaction data. Most data in chemistry is represented by unstructured text, and despite the vastness of the organic chemistry literature (papers, patents), manual conversion from unstructured text to structured data remains a largely manual endeavor. Software tools for this task would facilitate downstream applications such as reaction prediction and condition recommendation.

Does a subset of mature T-cell leukemias with features akin to T-cell prolymphocytic leukemia but lacking rearrangement of the represent peripheral T-cell lymphoma, NOS in a leukemic phase?

In the current WHO classification, a T-cell prolymphocytic leukemia (T-PLL) diagnosis requires lymphocytosis of >5 × 109/L, evidence of monoclonality, and or rearrangement. However, the 2019 consensus document suggested that in the absence of rearrangement of -family, the presence of abnormalities involving chromosome 11 (11q22.3; ATM), chromosome 8 (idic(8)(p11), t(8;8), trisomy 8q), 5, 12, 13, 22, or a complex karyotype, as well as involvement specific sites (e.

Breast Cancer Index in Premenopausal Women With Early-Stage Hormone Receptor-Positive Breast Cancer.

Importance: Adjuvant ovarian function suppression (OFS) with oral endocrine therapy improves outcomes for premenopausal patients with hormone receptor-positive (HR+) breast cancer but adds adverse effects. A genomic biomarker for selecting patients most likely to benefit from OFS-based treatment is lacking.

Objective: To assess the predictive and prognostic performance of the Breast Cancer Index (BCI) for OFS benefit in premenopausal women with HR+ breast cancer.

Peer support for patients with opioid use disorder in the emergency department: A narrative review.

Faced with a growing opioid overdose crisis, emergency departments (EDs) are increasingly hiring peers-people with lived experiences of addiction and recovery-to work with patients in the ED who have opioid use disorders (OUDs) or who have experienced an opioid overdose. Despite a clear need for more support for patients with OUD and rapid expansion in grant funding for peer programs, there are limited data on how these programs affect clinical outcomes and how they are best implemented within the ED. In this narrative review, we synthesize the existing evidence on how to develop and implement peer programs for OUD in the ED setting.

Generalizable clinical note section identification with large language models.

Objectives: Clinical note section identification helps locate relevant information and could be beneficial for downstream tasks such as named entity recognition. However, the traditional supervised methods suffer from transferability issues. This study proposes a new framework for using large language models (LLMs) for section identification to overcome the limitations.

Circulating sphingolipids in relation to cognitive decline and incident dementia: The Cardiovascular Health Study.

Introduction: Whether circulating levels of sphingolipids are prospectively associated with cognitive decline and dementia risk is uncertain.

Methods: We measured 14 sphingolipid species in plasma samples from 4488 participants (mean age 76.2 years; 40% male; and 25% apolipoprotein E ( ε4 allele carriers).

Towards automated inclusion of autoxidation chemistry in models: from precursors to atmospheric implications.

In the last few decades, atmospheric formation of secondary organic aerosols (SOA) has gained increasing attention due to their impact on air quality and climate. However, methods to predict their abundance are mainly empirical and may fail under real atmospheric conditions. In this work, a close-to-mechanistic approach allowing SOA quantification is presented, with a focus on a chain-like chemical reaction called "autoxidation".

Cardiovascular Risks in People With Narcolepsy: Expert Panel Consensus Recommendations.

Background: Observational and retrospective studies suggest that people with narcolepsy may have an increased prevalence of cardiovascular and cardiometabolic comorbidities and may be at greater risk for future cardiovascular events. An expert consensus panel was formed to establish agreement on the risk of hypertension and cardiovascular/cardiometabolic disease in people with narcolepsy and to develop strategies to mitigate these risks.

Methods And Results: Experts in sleep medicine and cardiology were selected to participate in the panel.

PD-L1 macrophage and tumor cell abundance and proximity to T cells in the pretreatment large B-cell lymphoma microenvironment impact CD19 CAR-T cell immunotherapy efficacy.

CD19-targeted chimeric antigen receptor T-cell (CAR-T) immunotherapy has transformed the management of relapsed/refractory large B-cell lymphoma (LBCL), yet durable remissions are observed in less than half of treated patients. The tumor microenvironment (TME) is a key and understudied factor impacting CD19 CAR-T therapy outcomes. Using NanoString nCounter transcriptome profiling ( = 24) and multiplex immunohistochemistry (mIHC,  = 15), we studied the TME in pretreatment biopsies from patients with LBCL undergoing CD19 CAR-T therapy.

The temperate marine Peruvian Province: How history accounts for its unusual biota.

The Peruvian Province, from 6° S in Peru to 42° S in Chile, is a highly productive coastal marine region whose biology and fossil record have long been studied separately but never integrated. To understand how past events and conditions affected today's species composition and interactions, we examined the role of extinction, colonization, geologic changes to explain previously unrecognized peculiar features of the biota and to compare the Peruvian Province's history to that of other climatically similar temperate coasts. We synthesized all available data on the benthic (or benthically feeding) biota, with emphasis on fossilizable taxa, for the interval from the Miocene (23-5.

Epidemiology and risk stratification of young infants presenting to the emergency department with hypothermia.

Objective: Hypothermic infants are presumed to be at high risk for a serious bacterial infection (SBI) or herpes simplex virus (HSV) infection. In contrast to febrile infants, the emergency department (ED) management of hypothermic infants is variable in the absence of consensus guidelines, potentially resulting in low-value care and missed diagnoses. We investigated the diagnostic workup conducted for hypothermic infants in our academic pediatric ED, the incidence of SBI and HSV infection, and risk factors associated with infection.

Contrasting effect of hybridization on genetic differentiation in three rockfish species with similar life history.

Hybridization can provide evolutionary benefits (e.g., population resilience to climate change) through the introduction of adaptive alleles and increase of genetic diversity.

Early Childhood Screening Practices and Barriers: A National Survey of Primary Care Pediatricians.

Background And Objectives: The American Academy of Pediatrics recommends screening during the first 3 years of life for developmental risk/delay, maternal depression, and social determinants of health (SDOH) using standardized tools. Adoption of these guidelines has been gradual, and barriers to screening are as varied as pediatric practices are themselves.

Methods: We analyzed 2019 American Academy of Pediatrics Periodic Survey data.

Back to the future: Using herbarium specimens to isolate nodule-associated bacteria.

Herbarium specimens are increasingly being used as sources of information to understand the ecology and evolution of plants and their associated microbes. Most studies have used specimens as a source of genetic material using culture-independent approaches. We demonstrate that herbarium specimens can also be used to culture nodule-associated bacteria, opening the possibility of using specimens to understand plant-microbe interactions at new spatiotemporal scales.

Developing, characterizing and modeling CRISPR-based point-of-use pathogen diagnostics.

Recent years have seen intense interest in the development of point-of-care nucleic acid diagnostic technologies to address the scaling limitations of laboratory-based approaches. Chief among these are combinations of isothermal amplification approaches with CRISPR-based detection and readouts of target products. Here, we contribute to the growing body of rapid, programmable point-of-care pathogen tests by developing and optimizing a one-pot NASBA-Cas13a nucleic acid detection assay.

Stay or go? Changing breeding conditions affect sexual difference in colony attendance strategies of Atlantic puffins .

Male and female birds have different roles in reproduction and, thereby in their reproductive investment, which in turn may increase negative effects of poorer breeding conditions caused by e.g., climate change or ecosystem regime shifts.

Addition of Social Determinants of Health to Coronary Heart Disease Risk Prediction: The Multi-Ethnic Study of Atherosclerosis.

Background: Social determinants of health (SDoH) are associated with cardiovascular risk factors and outcomes; however, they are absent from risk prediction models. We aimed to assess if the addition of SDoH improves the predictive ability of the MESA (Multi-Ethnic Study of Atherosclerosis) Risk Score.

Methods And Results: This was a community-based prospective population cohort study that enrolled 6286 men and women, ages 45-84 years, who were free of clinical coronary heart disease (CHD) at baseline.

Gastrointestinal endoscopy training in the United States: Program structure and competence assessment.

The general principles of gastrointestinal endoscopy training in the United States were formulated and summarized more than a decade ago and the principles have been consistent until now. To summarize, trainees should be prepared to (i) appropriately recommend endoscopic procedures as indicated by the findings of the consultative evaluation, with an explicit understanding of accepted specific indications, contraindications, and diagnostic/therapeutic alternatives, (ii) perform procedures safely, completely, and expeditiously, including possessing a thorough understanding of the principles of conscious sedation/analgesia techniques, the use of anesthesia-assisted sedation where appropriate, and pre-procedure clinical assessment and patient monitoring, (iii) correctly interpret endoscopic findings and integrate them into medical or endoscopic therapy, (iv) identify risk factors for each procedure, understand how to minimize each, and recognize and appropriately manage complications when they occur, (v) acknowledge the limitations of endoscopic procedures and personal skills and know when to request help, and (vi) understand the principles of quality measurement and improvement. This article provides an overview of the endoscopy training system and structure, evaluation scheme, and competence and credentialing process in the United States.
