Magnetic resonance imaging (MRI) protocoling can be time- and resource-intensive, and protocols can often be suboptimal dependent upon the expertise or preferences of the protocoling radiologist. Providing a best-practice recommendation for an MRI protocol has the potential to improve efficiency and decrease the likelihood of a suboptimal or erroneous study. The goal of this study was to develop and validate a machine learning-based natural language classifier that can automatically assign the use of intravenous contrast for musculoskeletal MRI protocols based upon the free-text clinical indication of the study, thereby improving efficiency of the protocoling radiologist and potentially decreasing errors...

Sandrine Duverne, Etienne Koechlin
The human prefrontal cortex (PFC) subserves cognitive control, that is, the ability to form behavioral strategies that coordinate actions and thoughts in relation to internal goals. Cognitive control involves the medial and lateral PFC but we still poorly understand how these regions guide strategy selection according to expected rewards. We addressed this issue using neuroimaging, computational modeling and model-based analyses of information flows between medial and lateral PFC. We show here that the (dorsal) medial PFC encodes and conveys to lateral PFC reward expectations driving strategy selection, while strategy selection originates in lateral PFC and propagates backward to medial PFC...

Cell-based therapies hold significant promise for infants at risk for cerebral palsy (CP) from perinatal brain injury (PBI). PBI leading to CP results from multi-faceted damage to neural cells. Complex developing neural networks are injured by neural cell damage plus unique perturbations in cell signaling. Given that cell-based therapies can simultaneously repair multiple injured neural components during critical neurodevelopmental windows, these interventions potentially offer efficacy for patients with CP...

This Special Issue examines ethical challenges in community psychology research and practice. The literature on ethics in community psychology has remained largely abstract and aspirational, with few concrete examples and case studies, so the goal of this Special Issue was to expand our written discourse about ethical dilemmas in our field. In these articles, researchers and practitioners share stories of specific ethical challenges they faced and how they sought to resolve them. These first-person narratives examine how ethical challenges come about, how community psychology values inform ethical decision making, and how lessons learned from these experiences can inform an ethical framework for community psychology...

In the March 2014 issue of American Journal of Community Psychology, we published an article that examined the tension between two core values in the field of community psychology: promoting contextual conditions that foster respect for diversity and promoting contextual conditions that foster sense of community. We concluded that processes of social network formation could help explain why diversity and sense of community are seemingly incompatible goals. The study's findings initially disseminated through the usual academic channels, and later through mainstream media outlets...

BACKGROUND: In the current era, trainees frequently use unvetted online resources for their own education, including viewing surgical videos on YouTube. While operative videos are an important resource in surgical education, YouTube content is not selected or organized by quality but instead is ranked by popularity and other factors. This creates a potential for videos that feature poor technique or critical safety violations to become the most viewed for a given procedure. METHODS: A YouTube search for "Laparoscopic cholecystectomy" was performed...

PURPOSE: The Global Early Adolescent Study (GEAS) was launched in 2014 with the primary goal of understanding the factors in early adolescence that predispose young people to subsequent sexual risks, and conversely, those that promote healthy sexuality across different cultural contexts. The present article describes the methodology that was used for the first phase of GEAS, which consisted of conducting qualitative research to understand the gendered transitions into adolescence and the role that gender norms play within the key relationships of adolescents...

Previous research in spatial cognition has often relied on simple spatial tasks in static environments in order to draw inferences regarding navigation performance. These tasks are typically divided into categories (e.g., egocentric or allocentric) that reflect different two-systems theories. Unfortunately, this two-systems approach has been insufficient for reliably predicting navigation performance in virtual reality (VR). In the present experiment, participants were asked to learn and navigate towards goal locations in a virtual city and then perform eight simple spatial tasks in a separate environment...

BACKGROUND: Global health academic partnerships are centered around a core tension: they often mirror or reproduce the very cross-national inequities they seek to alleviate. On the one hand, they risk worsening power dynamics that perpetuate health disparities; on the other, they form an essential response to the need for healthcare resources to reach marginalized populations across the globe. OBJECTIVES: This study characterizes the broader landscape of global health academic partnerships, including challenges to developing ethical, equitable, and sustainable models...

Training in patient safety, quality, and management is widely recognized as an important element of graduate medical education. These concepts have been intertwined in pathology graduate medical education for many years, although training programs face challenges in creating explicit learning opportunities in these fields. Tangibly involving pathology residents in management and quality improvement projects has the potential to teach and reinforce key concepts and further fulfill Accreditation Council for Graduate Medical Education goals for pursuing projects related to patient safety and quality improvement...

Plants are ubiquitous and found in virtually every ecosystem on Earth, but their biology is often poorly understood, and inaccurate ideas about how plants grow and function abound. Many articles have been published documenting student misconceptions about photosynthesis and respiration, but there are substantially fewer on such topics as plant cell structure and growth; plant genetics, evolution, and classification; plant physiology (beyond energy relations); and plant ecology. The available studies of misconceptions held on those topics show that many are formed at a very young age and persist throughout all educational levels...

MOTIVATION: Superparamagnetic relaxometry (SPMR) is an emerging technology that holds potential for use in early cancer detection. Measurement of the magnetic field after the excitation of cancer-bound superparamagnetic iron oxide nanoparticles (SPIONs) enables the reconstruction of SPIONs spatial distribution and hence tumor detection. However, image reconstruction often requires solving an ill-posed inverse problem that is computationally challenging and sensitive to measurement uncertainty...

BACKGROUND: Governance, which includes decision-making at all levels of the health system, and information have been identified as key, interacting levers of health system strengthening. However there is an extensive literature detailing the challenges of supporting health managers to use formal information from health information systems (HISs) in their decision-making. While health information needs differ across levels of the health system there has been surprisingly little empirical work considering what information is actually used by primary healthcare facility managers in managing, and making decisions about, service delivery...

Representative Learning Design (RLD) is a framework for assessing the degree to which experimental or practice tasks simulate key aspects of specific performance environments (i.e. competition). The key premise being that when practice replicates the performance environment, skills are more likely to transfer. In applied situations, however, there is currently no simple or quick method for coaches to assess the key concepts of RLD (e.g. during on-court tasks). The aim of this study was to develop a tool for coaches to efficiently assess practice task design in tennis...

Stress induction reduces people's ability to modify their instrumental choices following changes in the value of outcomes, but the mechanisms underpinning this effect have not been specified because previous studies have lacked crucial control conditions. To address this, the current study had participants learn two instrumental responses for food and water, respectively, before water was devalued by specific satiety. Choice between these two responses was then measured in extinction, reacquisition and Pavlovian to instrumental transfer (PIT) tests...

Introductory biology courses provide an important opportunity to prepare students for future courses, yet existing cookbook labs, although important in their own way, fail to provide many of the advantages of semester-long research experiences. Engaging, authentic research experiences aid biology students in meeting many learning goals. Therefore, overlaying a research experience onto the existing lab structure allows faculty to overcome barriers involving curricular change. Here we propose a working model for this overlay design in an introductory biology course and detail a means to conduct this lab with minimal increases in student and faculty workloads...
