Health professionals' experiences and views on obstetric ultrasound in Victoria, Australia: A cross-sectional survey.

Background: Obstetric ultrasound is an important tool, aiding in screening, diagnosis, and surveillance throughout pregnancy.

Aims: To explore obstetric doctors', midwives', and sonographers' experiences and views of obstetric ultrasound in Victoria, Australia. To investigate the increasing role of obstetric ultrasound for clinical management, and the adequacy of resources and training for appropriate use of ultrasound in clinical management.

Interventions to prevent iatrogenic anemia: a Laboratory Medicine Best Practices systematic review.

Background: As many as 90% of patients develop anemia by their third day in an intensive care unit (ICU). We evaluated the efficacy of interventions to reduce phlebotomy-related blood loss on the volume of blood lost, hemoglobin levels, transfusions, and incidence of anemia.

Methods: We conducted a systematic review and meta-analysis using the Laboratory Medicine Best Practices (LMBP) systematic review methods for rating study quality and assessing the body of evidence.

Shape-Changing Materials Using Variable Stiffness and Distributed Control.

We describe a robotic material that tightly integrates sensing, actuation, computation, and communication to perform autonomous shape change. The composite consists of multiple cells, each with the ability to control their local stiffness (by Joule heating of a thermoplastic) and communicate with their local neighbors. We also present a distributed algorithm for calculating the inverse kinematic solution of the resulting N-body system by iteratively solving a series of problems with reduced kinematics.

Anemia, bleeding, and blood transfusion in the intensive care unit: causes, risks, costs, and new strategies.

The definition of anemia is controversial and varies with the sex, age, and ethnicity of the patient. Anemia afflicts half of hospitalized patients and most elderly hospitalized patients. Acute anemia in the operating room or intensive care unit is associated with increased morbidity as well as other adverse outcomes, including death.

Use of an electronic decision support tool improves management of simulated in-hospital cardiac arrest.

Introduction: Adherence to advanced cardiac life support (ACLS) guidelines during in-hospital cardiac arrest (IHCA) is associated with improved outcomes, but current evidence shows that sub-optimal care is common. Successful execution of such protocols during IHCA requires rapid patient assessment and the performance of a number of ordered, time-sensitive interventions. Accordingly, we sought to determine whether the use of an electronic decision support tool (DST) improves performance during high-fidelity simulations of IHCA.

CPEB1 regulates beta-catenin mRNA translation and cell migration in astrocytes.

A crucial step in directed cell migration is the recruitment of cytoskeletal regulatory and signaling proteins to the leading edge of the cell. One protein localized to the leading edge of a migrating astrocyte is beta-catenin. Using an in vitro wound-healing assay, we show that the localization of beta-catenin to the leading edge is dependent upon new protein synthesis at the time of wounding.

Cytoplasmic polyadenylation element binding protein 1-mediated mRNA translation in Purkinje neurons is required for cerebellar long-term depression and motor coordination.

The ability of neurons to modify synaptic connections is critical for proper brain development and function in the adult. It is now clear that changes in synaptic strength are often accompanied by changes in synaptic morphology. This synaptic plasticity can be maintained for varying lengths of time depending on the type of neuronal activity that first induced the changes.
