Background: Valve-sparing root replacement (VSRR) requires a unique skill set. This study aimed to examine the influence of surgeon's procedural volume on outcomes of VSRR. Methods: This retrospective study included 1697 patients from 2 large, high-volume aortic centers who underwent aortic root replacement (ARR) between 2004 and 2021 and were potentially eligible for VSRR. Surgeons were classified as performing

Introduction To characterize glucose levels during uncomplicated pregnancies, defined as pregnancy with a hemoglobin A1c 120 mg/dL (6.7 mmol/L) was 11%, and median per cent time >140 mg/dL (7.8 mmol/L) was 2.5%. Mean post-prandial peak glucose was 126±22 mg/dL (7.0±1.2 mmol/L), and mean post-prandial glycemic excursion was 36±22 mg/dL (2.0±1.2 mmol/L). Higher mean glucose levels were low to moderately associated with pregnant individuals with higher BMIs (103±6 mg/dL (5.7±0.3 mmol/L) for BMI ≥30.0 kg/m2 vs 96±7 mg/dL (5.3±0.4 mmol/L) for BMI 18.5–

OBJECTIVES/GOALS: The objective is to assess the effect of pesticide exposure (individually and pesticide mixtures) on the immune response to COVID-19 in children. The goal is to improve scientific knowledge on factors affecting COVID-19 and identify a potentially modifiable factor to reduce disparities in COVID-19 morbidity. METHODS/STUDY POPULATION: Blood samples will be obtained from 50 children with asthma two time points; baseline and 12 months later. SARS-CoV-2 infection or vaccination will be determined with blood exposome RNA analyses.. Immunological response will be measured using neutralizing, phagocytizing, and NK-activating anti-body responses biomarkers. Pesticide exposure will be measured via urinary pesticide metabolites (UPMs). For individual metabolites multivariable analyses for each pesticide will be conducted using generalized estimating equation (GEE) models with compound symmetry correlation to account for the repeated measures design. To assess the pesticide mixture, weighted quantile sum regression (WQS) will be used. RESULTS/ANTICIPATED RESULTS: The main hypothesis is that increased pesticide exposure results in a reduction in the immunological response to SARS-CoV-2 infection and the COVID-19 vaccine. Therefore, we anticipate that increasing concentrations of individual UPMs as well as the increasing index will result in reductions in markers of the immune response to SARS-CoV-2 infection and the COVID-19 vaccine. DISCUSSION/SIGNIFICANCE: Exposure to pesticides is a modifiable environmental factor. If pesticides are found to alter the immune response to COVID-19 infection and vaccination, these data will provide an evidence base for efforts to reduce pesticide exposure in children.

Purpose This paper presents qualitative research findings from the evaluation of a Parkinson’s Dance well-being venture in the UK. Methods Qualitative data was gathered to see how bespoke dancing sessions helped people with Parkinson’s (PwP) to manage their conditions and improve their lives and prospects. Principles of a participatory approach were incorporated and methods included semi-structured interviewing, researchers participant observation and an elicitation-based activity. Nineteen PwP, six carers, four dance artists and seven helpers participated in the study. Results Participating in Parkinson’s Dance sessions meant that PwP could experience the possibilities to dance, develop a “can do” attitude, experience fun, enjoyment, social connection, exercise, movement to music, improvement and/or maintenance of their balance, suppleness, coordination and confidence with movement, symptoms being pushed back and ability to learn new things. Conclusions Our findings add to the evidence-base about the benefits of dance for people experiencing Parkinson’s and through novel application of the Life-world based well-being framework of K. T. Galvin and Todres (2011) we propose a theoretical basis for Parkinson’s Dance as a resource for well-being. There is scope to consider application of the well-being framework to other arts activities and as the basis of an arts and well-being evaluation tool.

Abstract Objectives In light of the youth mental health crisis, as 1 in 5 children have a mental disorder diagnosis by age 3, identification of transdiagnostic behavioral vulnerability prior to impairing psychopathology must occur at an earlier phase of the clinical sequence. Here, we lay the groundwork for a pragmatic irritability measure to identify at‐risk infant‐toddlers. Methods Data comprised N = 350 diverse infant‐toddlers and their mothers assessed at ∼14 months old for irritability (Multidimensional Assessment Profiles‐ Temper Loss‐Infant/Toddler (MAPS‐TL‐IT) and impairment (Early Childhood Irritability‐Related Impairment Interview, E‐CRI; and Family Life Impairment Scale (FLIS). Bimonthly follow‐up surveys assessed impairment (FLIS) over the following year. Results Stepwise logistic regression indicated that 5 MAPS‐TL‐IT items were most informative for differentiating concurrent impairment on the FLIS: “frustrated about small things”; “hit, bite, or kick during tantrums”; “trouble cheering up when grumpy”; “grumpy during fun activities” and “tantrums in public”. With this summed score, Receiver Operating Characteristics analysis differentiating concurrent impairment on the E‐CRI indicated good classification accuracy for (Area under the curve = 0.755, p

Bicuspid aortic valve (BAV) can be both sporadic and hereditary, is phenotypically variable, and genetically heterogeneous. The clinical presentation of BAV is diverse and commonly associated with a high prevalence of valvular dysfunction producing altered hemodynamics and aortic abnormalities (e.g., aneurysm and dissection). The thoracic aortic aneurysm (TAA) in BAV frequently involves the proximal aorta, including the aortic root, ascending aorta, and aortic arch, but spares the aorta distal to the aortic arch. While the ascending aortic aneurysm might be affected by both aortopathy and hemodynamics, the aortic root aneurysm is considered to be more of a consequence of aortopathy rather than hemodynamics, especially in younger patients. The management of aortic aneurysm in BAV has been very controversial because the molecular mechanism is unknown. Increasing evidence points toward the BAV root phenotype [aortic root dilation with aortic insufficiency (AI)] as having a higher risk of catastrophic aortic complications. We propose more aggressive surgical approaches toward the BAV with root phenotype.

Infection of glial cells by the human polyomavirus JC (JCV) causes progressive multifocal leukoencephalopathy (PML). JCV Encephalopathy (JCVE) is a newly identified disease characterized by JCV infection of cortical pyramidal neurons. The virus JCVCPN associated with JCVE contains a unique 143 base pair deletion in the agnogene. Contrary to most JCV brain isolates, JCVCPN has an archetype-like regulatory region (RR) usually found in kidney strains. This provided us with the unique opportunity to determine for the first time how each of these regions contributed to the phenotype of JCVCPN. We characterized the replication of JCVCPN compared to the prototype virus JCVMad-1 in kidney, glial and neuronal cell lines. We found that JCVCPN is capable of replicating viral DNA in all cell lines tested, but is unable to establish persistent infection seen with JCVMad-1. JCVCPN does not have an increased ability to replicate in the neuronal cell line tested. To determine whether this phenotype results from the archetype-like RR or the agnogene deletion, we generated chimeric viruses between JCVCPN of JCVMad-1. We found that the deletion in the agnogene is the predominant cause of the inability of the virus to maintain a persistent infection, with the introduction of a full length agnogene, either with or without agnoprotein expression, rescues the replication of JCVCPN. Studying this naturally occurring pathogenic variant of JCV provides a valuable tool for understanding the functions of the agnogene and RR form in JCV replication.

The article presents a study on the correlation between Undergraduate General Point Average (GPA) and Graduate Record Examination (GRE) and Academic Success and Passing Rates of the National Certification Examination (NCE) for Nurse Anesthetist students in the U.S. It notes that admission variables and examination performance rates could not be performed due to lack of variability. The research aims to identify the performance indicators of nursing programs to carry out change in the profession. It cites that GRE and GPA were predictors of the tests. Moreover, GRE score is the only significant predictor of unique variance.
