Unraveling the elongating bovine conceptus microenvironment: identification of gene transcripts and proteins along the conceptus-maternal interface in cattle.

The bovine conceptus elongates near Day 16 of development and releases interferon-tau (IFNT), disrupting the endometrial luteolytic mechanism to sustain luteal P4 and pregnancy. Conceptus factors other than IFNT modify local endometrial activities to support pregnancy; however, the microenvironment is largely uncharacterized. We utilized a bovine conceptus-endometrial culture system to elucidate the microenvironment in the form of RNA and protein.

Direct Apical Cannulation With Protek Duo Rapid Deployment Cannula via Mini Thoracotomy for Ambulatory Venoarterial-Extracorporeal Membrane Oxygenation.

National trends show rapid increases in the use of mechanical circulatory support devices (MCSD) over the last 20 years. While current literature has not proven a mortality benefit in cardiogenic shock as a complication of acute myocardial infarction (AMI-CS) with percutaneous MCSD, these devices are vital to maximizing cardiopulmonary parameters for definitive therapy. To minimize complications, many different techniques have been described including a novel off-pump direct apical cannulation for venoarterial-extracorporeal membrane oxygenation (VA-ECMO).

Intrapulmonary administration of recombinant activated factor VII in pediatric, adolescent, and young adult oncology and hematopoietic cell transplant patients with pulmonary hemorrhage.

Introduction: Diffuse alveolar hemorrhage (DAH) is a devastating disease process with 50-100% mortality in oncology and hematopoietic cell transplant (HCT) recipients. High concentrations of tissue factors have been demonstrated in the alveolar wall in acute respiratory distress syndrome and DAH, along with elevated levels of tissue factor pathway inhibitors. Activated recombinant factor VII (rFVIIa) activates the tissue factor pathway, successfully overcoming the tissue factor pathway inhibitor (TFPI) inhibition of activation of Factor X.

Hepatic steatosis modeling and MRI signal simulations for comparison of single- and dual-R2* models and estimation of fat fraction at 1.5T and 3T.

Background And Objective: Magnetic resonance imaging (MRI) has emerged as a noninvasive clinical tool for assessment of hepatic steatosis. Multi-spectral fat-water MRI models, incorporating single or dual transverse relaxation decay rate(s) (R2*) have been proposed for accurate fat fraction (FF) estimation. However, it is still unclear whether single- or dual-R2* model accurately mimics in vivo signal decay for precise FF estimation and the impact of signal-to-noise ratio (SNR) on each model performance.

Predicting Performance at Graduation From Early ACGME Milestone Ratings: Longitudinal Learning Analytics in Professionalism and Communication in Vascular Surgery.

Objective: Program directors in surgical disciplines need more tools from the ACGME to help them use Milestone ratings to improve trainees' performance. This is especially true in competencies that are notoriously difficult to measure, such as professionalism (PROF) and interpersonal and communication skills (ICS). It is now widely understood that skills in these two areas have direct impact on patient care outcomes.

Molecular classification and outcome of children with rare CNS embryonal tumors: results from St. Jude Children's Research Hospital including the multi-center SJYC07 and SJMB03 clinical trials.

Methylation profiling has radically transformed our understanding of tumors previously called central nervous system primitive neuro-ectodermal tumors (CNS-PNET). While this marks a momentous step toward defining key differences, reclassification has thrown treatment into disarray. To shed light on response to therapy and guide clinical decision-making, we report outcomes and molecular features of children with CNS-PNETs from two multi-center risk-adapted studies (SJMB03 for patients ≥ 3 years; SJYC07 for patients < 3 years) complemented by a non-protocol institutional cohort.

Treatment of Ipsilateral Femoral Neck and Shaft Fractures With Cannulated Screws and Antegrade Reconstruction Nail.

Ipsilateral femoral neck and shaft fractures are challenging injuries, and there are different fixation options but no consensus on a superior construct. Our preferred method is cannulated screw fixation of the femoral neck and antegrade reconstruction nailing of the shaft. Compressive fixation of the femoral neck fracture with cancellous lag screws followed by reconstruction nail placement provides compressive fixation and fixed angle support of the neck fracture while allowing for more optimal treatment of femoral shaft fractures at or above the isthmus.

Complete remission with ibrutinib after allogeneic stem cell transplant for central nervous system relapse of mantle cell lymphoma: A case report and literature review.

Central nervous system (CNS)-relapsed mantle cell lymphoma (MCL) is a rare, aggressive non-Hodgkin lymphoma without a standard treatment. Ibrutinib has shown promising results for inducing remission in other non-Hodgkin lymphomas and may be considered as successful treatment for CNS-relapsed MCL in the future as well.

A striatal interneuron circuit for continuous target pursuit.

Most adaptive behaviors require precise tracking of targets in space. In pursuit behavior with a moving target, mice use distance to target to guide their own movement continuously. Here, we show that in the sensorimotor striatum, parvalbumin-positive fast-spiking interneurons (FSIs) can represent the distance between self and target during pursuit behavior, while striatal projection neurons (SPNs), which receive FSI projections, can represent self-velocity.

Doppler evaluation of the fetal pulmonary artery pressure.

Background The Doppler effect has allowed the characterization of several vessels in maternal-fetal circulation that have been used for practical purposes. Our review of the literature showed a paucity of information about fetal pulmonary artery pressure (FMPAP) and its behavior in regard to gestational age (GA). The objectives of the study were to evaluate a formula to calculate the main FMPAP and its correlation with GA.

Community-based recruitment and retention strategies in a multi-site longitudinal project evaluating an asthma self-management intervention for adolescents are presented. Successful recruitment strategies depended on the geographic and cultural characteristics of each study site.

End-Stage Renal Disease Increases Rates of Adverse Glucose Events When Treating Diabetic Ketoacidosis or Hyperosmolar Hyperglycemic State.

Treatment guidelines for diabetic emergencies are well described in patients with normal to moderately impaired kidney function. However, management of patients with end-stage renal disease (ESRD) is an ongoing challenge. This article describes a retrospective study comparing the rates of adverse glucose events (defined as hypoglycemia or a decrease in glucose >200 mg/dL/h) between patients with ESRD and those with normal kidney function who were admitted with diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS).

Generating stability in elderly acetabular fractures-A biomechanical assessment.

Background & Objectives: As the overall health and life expectancy increases in the United States, the incidence of fragility fractures in elderly patients also continues to increase. Given their medical comorbidities and decreased bone mineral density, acetabular fractures in the elderly population present a significant challenge to the orthopaedic trauma surgeon. The anterior column posterior hemitransverse (ACPHT) fracture pattern is a common fracture pattern in this population, and is often associated with central subluxation/dislocation of the femoral head with articular impaction.
