Development of an Electronic Health Record-Based Clinical Decision Support Tool for Patients With Lynch Syndrome.

Purpose: To develop an electronic health record (EHR)-based clinical decision support (CDS) tool to promote guideline-recommended cancer risk management among patients with Lynch syndrome (LS), an inherited cancer syndrome that confers an increased risk of colorectal and other cancer types.

Materials And Methods: We conducted a cross-sectional study to determine the baseline prevalence and predictors of guideline-recommended colonic surveillance and annual genetics program visits among patients with LS. Multivariable log-binomial regressions estimated prevalence ratios (PRs) of cancer risk management adherence by baseline sociodemographic and clinical characteristics.

Antiracism defined as equitable sociocultural interactions in prekindergarten: Classroom racial composition makes a difference.

This study used secondary data from the My Teaching Partner-Math/Science 2013-2016 randomized control trial to explore whether equitable sociocultural classroom interactions (see Curenton et al., 2019) were associated with the skills of 105 four- and five-year-olds (52% boys; drawn from 20 unique video recordings of preschool teachers/classrooms; 43% were Black, Latine, Asian, or other racially marginalized learners). Equitable interactions predicted children's skills with effect sizes ranging from small (0.

Super-resolution surface slope metrology of x-ray mirrors.

We present experimental, analytical, and numerical methods developed for reconstruction (deconvolution) of one-dimensional (1D) surface slope profiles over the spatial frequency range where the raw data are significantly perturbed due to the limited resolution of the measurement instrument. We characterize the spatial resolution properties of a profiler with the instrument's transfer function (ITF). To precisely measure the ITF, we apply a recently developed method utilizing test surfaces with 1D linear chirped height profiles of constant slope amplitude.

Robotic resection of an esophageal leiomyoma.

The use of robotic thoracic surgery as an alternative to open resections or video assisted thoracoscopy has increased in recent years due to its many potential benefits to patients. These benefits include less pain and therefore less use of pain medication, shorter hospital stays, faster recovery, and fewer complications.  This video tutorial describes the robotic resection of a 37-mm by 30-mm esophageal leiomyoma.

Compartment syndrome of the hand as a complication of prolonged mechanical cardiopulmonary resuscitation.

A 45-year-old man suffered compartment syndrome of the hands as a complication of prolonged cardiopulmonary resuscitation. He was admitted following a hypothermic out-of-hospital cardiac arrest due to cold-water submersion. The patient was in cardiac arrest for 4 h with mechanical cardiopulmonary resuscitation delivered using the Lund University Cardiac Arrest System (Jolife AB, Lund, Sweden).

The Effects of Enrolling in Oversubscribed Prekindergarten Programs Through Third Grade.

This study leverages naturally occurring lotteries for oversubscribed Boston Public Schools prekindergarten program sites between 2007 and 2011, for 3,182 children (M = 4.5 years old) to estimate the impacts of winning a first choice lottery and enrolling in Boston prekindergarten versus losing a first choice lottery and not enrolling on children's enrollment and persistence in district schools, grade retention, special education placement, and third-grade test scores. There are large effects on enrollment and persistence, but no effects on other examined outcomes for this subsample.

Polarization-driven spin precession of mesospheric sodium atoms: publisher's note.

This publisher's note corrects an error in the author listing of Opt. Lett.43, 5825 (2018)OPLEDP0146-959210.

Polarization-driven spin precession of mesospheric sodium atoms.

We report experimental on-sky observations of atomic spin precession of mesospheric sodium driven by polarization modulation of a continuous-wave laser. A magnetic resonance was remotely detected from the ground by observing the enhancement of induced fluorescence when the driving frequency approached the precession frequency of sodium in the mesosphere, between 85 and 100 km altitude. The experiment was performed at La Palma, and the uncertainty (0.

Remote sensing of geomagnetic fields and atomic collisions in the mesosphere.

Magnetic-field sensing has contributed to the formulation of the plate-tectonics theory, mapping of underground structures on Earth, and the study of magnetism of other planets. Filling the gap between space-based and near-Earth observations, we demonstrate a remote measurement of the geomagnetic field at an altitude of 85-100 km. The method consists of optical pumping of atomic sodium in the mesosphere with an intensity-modulated laser beam, and ground-based observation of the resultant magneto-optical resonance near the Larmor precession frequency.

Suppression of the Nonlinear Zeeman Effect and Heading Error in Earth-Field-Range Alkali-Vapor Magnetometers.

The nonlinear Zeeman effect can induce splitting and asymmetries of magnetic-resonance lines in the geophysical magnetic-field range. This is a major source of "heading error" for scalar atomic magnetometers. We demonstrate a method to suppress the nonlinear Zeeman effect and heading error based on spin locking.

Tailorable dispersion in a four-wave mixing laser.

We present experimental results demonstrating controllable dispersion in a ring laser by monitoring the lasing-frequency response to cavity-length variations. Pumping on an N-type level configuration in Rb87, we tailor the intra-cavity dispersion slope by varying experimental parameters, such as pump-laser frequency, atomic density, and pump power. As a result, we can tune the pulling factor, i.

Magneto-optical cooling of atoms.

We propose an alternative method to laser cooling. Our approach utilizes the extreme brightness of a supersonic atomic beam, and the adiabatic atomic coilgun to slow atoms in the beam or to bring them to rest. We show how internal-state optical pumping and stimulated optical transitions, combined with magnetic forces, can be used to cool the translational motion of atoms.

Providing simulation experiences for large cohorts of 1st year nursing students: evaluating quality and impact.

To provide each student within a large cohort the opportunity to participate in a small group simulation that meets recognised quality indicators is a challenge for Bachelor of Nursing programmes in Australia. This paper, as part of a larger longitudinal study, describes one approach used to manage a simulation for 375 1st year nursing students and to report on the quality of the experience from the student's perspective. To ensure quality was maintained within the large cohort, aspects of the simulation were assessed against the following indicators: alignment with curriculum pedagogy and goals; preparation of students and staff; fidelity; and debriefing.

Drivers for renewal and reform of contemporary nursing curricula: a blueprint for change.

The creation of a curriculum blueprint appropriate to the development of a professional nurse who is practice-ready for the current and future context of health service delivery must take account of the extant context as well as an unpredictable and sometimes ambiguous future. The curriculum renewal process itself ought to challenge existing long held ideals, practices, and sacred cows within the health and higher education sectors. There is much to consider and importantly curriculum developers need to be mindful of reform within the health sector and health workforce education, as well as the concomitant vision and requirements of the nursing profession.

Magnetometry with mesospheric sodium.

Measurement of magnetic fields on the few 100-km length scale is significant for many geophysical applications including mapping of crustal magnetism and ocean circulation measurements, yet available techniques for such measurements are very expensive or of limited accuracy. We propose a method for remote detection of magnetic fields using the naturally occurring atomic sodium-rich layer in the mesosphere and existing high-power lasers developed for laser guide star applications. The proposed method offers a dramatic reduction in cost and opens the way to large-scale, parallel magnetic mapping and monitoring for atmospheric science, navigation, and geophysics.

Nonlinear magneto-optical rotation in the presence of a radio-frequency field.

We report measurements of nonlinear magneto-optical rotation (NMOR) for the D line of Rb atoms in an antirelaxation-coated vapor cell in the presence of a radio-frequency (rf) field. The experimental NMOR signals as a function of rf field frequency for various rf field powers are compared to a theoretical model based on the density-matrix formalism. The comparison between experiment and theory enables understanding of the ground-state atomic spin polarization dynamics, illustrated using plots of the probability distribution of the atomic angular momentum.

Production and detection of atomic hexadecapole at Earth's magnetic field.

Optical magnetometers measure magnetic fields with extremely high precision and without cryogenics. However, at geomagnetic fields, important for applications from landmine removal to archaeology, they suffer from nonlinear Zeeman splitting, leading to systematic dependence on sensor orientation. We present experimental results on a method of eliminating this systematic error, using the hexadecapole atomic polarization moment.

The nurse academic in the clinical learning setting: an evolving partnership role.

Student readiness for practice as a registered nurse can only be achieved through a committed and cooperative partnership between the tertiary and clinical sectors. One important role in the development and maintenance of clinical learning partnerships is that of the nurse academic. As nursing faculties continue to evolve this role it is important that positive initiatives be shared and challenges discussed.

Magnetic resonance imaging with an optical atomic magnetometer.

We report an approach for the detection of magnetic resonance imaging without superconducting magnets and cryogenics: optical atomic magnetometry. This technique possesses a high sensitivity independent of the strength of the static magnetic field, extending the applicability of magnetic resonance imaging to low magnetic fields and eliminating imaging artifacts associated with high fields. By coupling with a remote-detection scheme, thereby improving the filling factor of the sample, we obtained time-resolved flow images of water with a temporal resolution of 0.

Learning from success: improving undergraduate education through understanding the capabilities of successful nurse graduates.

This paper reports on a study of nursing graduates identified as high performers by their nursing unit managers. The study involved 17 graduates from two teaching hospitals, one in the inner city of Sydney and the other in regional New South Wales. The aim of this study was to identify the capabilities that were seen to be most important for successful nursing practice during the first 2-6 years following employment as registered nurses and to evaluate through backward mapping, the degree to which university programmes were developing these capabilities.

Can a quantum nondemolition measurement improve the sensitivity of an atomic magnetometer?

We consider the limitations due to noise (e.g., quantum projection noise and photon shot-noise) on the sensitivity of an idealized atomic magnetometer that utilizes spin squeezing induced by a continuous quantum nondemolition measurement.
