Preparing Students as Leaders with a Global Mindset: A Study Abroad Phenomenological Case Study

Research continues to stress the importance for college students to graduate with the skills to be successful as global-minded leaders in today’s evolving workforce. Although the typical study abroad programs can address this, critics point to some limitations. First, most study abroad programs are short-term, limiting students’ ability to internalize and apply cultural context upon their return to the United States. Second, although universities and colleges state the importance of developing students' cultural competencies, few have intentionally incorporated best practices for study abroad. The purpose of this phenomenological case study, therefore, was to explore how nine students from six different disciplines perceived a unique study abroad experience, designed to address some of the typical study abroad limitations. This interdisciplinary program was designed to immerse students in three European countries while participating in a formal learning cohort program that incorporated cognitive, experiential, and humanistic methodologies. The study also explored what role cross-cultural partnerships with companies, organizations, and community leaders played in enhancing the students’ application and integration of developing themselves as global- minded citizen leaders in their field of study. Data were collected through informal interviews with all nine students and supporting data included field observations, rich text, and results from the Global Mindset Inventory®. Utilizing a hybrid-coding scheme, researchers found four themes that emerged, supporting the notion that the cross-cultural pedagogical framework enhanced students’ self-efficacy as global-minded citizens, resulting from their interdisciplinary international experiences

Blood manufacturing methods affect red blood cell product characteristics and immunomodulatory activity

Transfusion of red cell concentrates (RCCs) is associated with increased risk of adverse outcomes that may be affected by different blood manufacturing methods and the presence of extracellular vesicles (EVs). We investigated the effect of different manufacturing methods on hemolysis, residual cells, cell-derived EVs, and immunomodulatory effects on monocyte activity. Thirty-two RCC units produced using whole blood filtration (WBF), red cell filtration (RCF), apheresis-derived (AD), and whole blood-derived (WBD) methods were examined (n = 8 per method). Residual platelet and white blood cells (WBCs) and the concentration, cell of origin, and characterization of EVs in RCC supernatants were assessed in fresh and stored supernatants. Immunomodulatory activity of RCC supernatants was assessed by quantifying monocyte cytokine production capacity in an in vitro transfusion model. RCF units yielded the lowest number of platelet and WBC-derived EVs, whereas the highest number of platelet EVs was in AD (day 5) and in WBD (day 42). The number of small EVs (<200 nm) was greater than large EVs (≥200 nm) in all tested supernatants, and the highest level of small EVs were in AD units. Immunomodulatory activity was mixed, with evidence of both inflammatory and immunosuppressive effects. Monocytes produced more inflammatory interleukin-8 after exposure to fresh WBF or expired WBD supernatants. Exposure to supernatants from AD and WBD RCC suppressed monocyte lipopolysaccharide-induced cytokine production. Manufacturing methods significantly affect RCC unit EV characteristics and are associated with an immunomodulatory effect of RCC supernatants, which may affect the quality and safety of RCCs

Expanding and developing the workforce to serve autistic people and people with intellectual disability

This paper considers current workforce issues facing psychological professionals working in NHS services, examining the challenges, and identifying opportunities to better meet the needs of autistic people and people with an intellectual disability (PwID) across the lifespan. The aim of this paper is to identify and publicly articulate the need for a coherent approach to guide the practice of psychological professionals when helping autistic people and/or PwID. It should be noted that the scope of the paper is limited to autism and intellectual disability. In addressing these broad groups and their co-occurring conditions and needs, we anticipate that many principles could be applied to other neurodevelopmental conditions. We also note the significant potential challenges in linking intellectual disability and autistic populations, hence have attempted – in drawing together a working group to write this paper – to ensure representation from a range of psychological professionals including those in policy, leadership, and training roles, those working in specialist or generic mental health services and undertaking clinical research across the lifespan. Objectives: ■ To help define and support clear action so that all sectors welcome and adequately support people with neurodevelopmental differences, including autistic people and/or PwID. ■ To play a role in the development, planning and evaluation of new psychological professions roles such as the Clinical Associates in Psychology (CAPS) and Education Mental Health Practitioners (EMHPs). ■ To reflect on the obstacles to recruiting to autism and learning disability services and to propose approaches to developing a sustainable psychological workforce in these areas. ■ To recognise where good examples of education and training programmes exist to address training, confidence and competence for all psychological professionals working with those who may be autistic and/or have an ID, and consider how to establish a more consistent approach to education, training and CPD across the workforce. ■ To engage in policy discussions around the current gaps, such as the demand for diagnostic assessments and support which significantly outstrips capacity, whilst highlighting unrealised opportunities, through for example, a systematic approach to training. ■ To advocate for the need for the voice of autistic people and PwID and their families/carers which is often absent from the design and offer of help.</p

Osmotic Tolerance Limits of Red Blood Cells from Umbilical Cord Blood

Effective methods for long-term preservation of cord red blood cells (RBCs) are needed to ensure a readily available supply of RBCs to treat fetal and neonatal anemia. Cryopreservation is a potential long-term storage strategy for maintaining the quality of cord RBCs for the use in intrauterine and neonatal transfusion. However, during cryopreservation, cells are subjected to damaging osmotic stresses during cryoprotectant addition and removal and freezing and thawing that require knowledge of osmotic tolerance limits in order to optimize the preservation process. The objective of this study was to characterize the osmotic tolerance limits of cord RBCs in conditions relevant to cryopreservation, and compare the results to the osmotic tolerance limits of adult RBCs. Osmotic tolerance limits were determined by exposing RBCs to solutions of different concentrations to induce a range of osmotic volume changes. Three treatment groups of adult and cord RBCs were tested: 1) isotonic saline, 2) 40% w/v glycerol, and 3) frozen-thawed RBCs in 40% w/v glycerol. We show that cord RBCs are more sensitive to shrinkage and swelling than adult RBCs, indicating that osmotic tolerance limits should be considered when adding and removing cryoprotectants. In addition, freezing and thawing resulted in both cord and adult RBCs becoming more sensitive to post-thaw swelling requiring that glycerol removal procedures for both cell types ensure that cell volume excursions are maintained below 1.7 times the isotonic osmotically active volume to attain good post-wash cell recovery. Our results will help inform the development of optimized cryopreservation protocol for cord RBCs.Keywords: Biobanking, Hydraulic permeability, Cryopreservation, Osmotic fragility, Transfusion medicine, Cryoprotectant, Erythrocyte, Hemolysi

Evaluation of a Hydrogel-Based Diagnostic Approach for the Point-of-Care Based Detection of Neisseria gonorrhoeae

Eleven primer pairs were developed for the identification of Neisseria gonorrhoeae. The sensitivity and specificity of these primers were evaluated by Real Time (RT)-PCR melt curve analyses with DNA from 145 N. gonorrhoeae isolates and 40 other Neisseria or non-Neisseria species. Three primer pairs were further evaluated in a hydrogel-based RT-PCR detection platform, using DNA extracted from 50 N. gonorrhoeae cultures. We observed 100% sensitivity and specificity in the hydrogel assay, confirming its potential as a point-of-care test (POCT) for N. gonorrhoeae diagnosis

An enclosed in-gel PCR amplification cassette with multi-target, multi-sample detection for platform molecular diagnostics

This work describes a self-contained, simple, disposable, and inexpensive gel capillary cassette for DNA amplification in near point of care settings. The cassette avoids the need for pumps or valves during raw sample delivery or polymerase chain reaction (PCR) amplification steps. The cassette contains capillary reaction units that can be stored at room temperature for up to 3 months. The current cassette configuration format can simultaneously tests up to 16 patients for two or more targets, accommodates different sample types on the same cassette, has integrated positive and negative controls and allows flexibility for multiple geometries. PCR reagents in the cassette are desiccated to allow storage at room temperature with rehydration by raw sample at the time of testing. The sample is introduced to the cassette via a transfer pipette simply by capillary force. DNA amplification was carried out in a portable prototype instrument for PCR thermal cycling with fluorescence detection of amplified products by melt curve analysis. To demonstrate performance, raw genital swabs and urine were introduced to the same cassette to simultaneously detect four sexually transmitted infections. Herpes Simplex Viruses (HSV-1 and HSV-2) were detected from raw genital swabs. Ureaplasma Urealyticum (UU) and Mycoplasma Homonis (MH) were detected from raw urine. Results for multiple patients were obtained in as little as 50'. This platform allows multiparameter clinical testing with a pre-assembled cassette that requires only the introduction of raw sample. Modification of the prototype device to accommodate larger cassettes will ultimately provide high throughput simultaneous testing of even larger numbers of samples for many different targets, as is required for most clinical applications. Combinations of wax and/or polymer cassettes holding capillary reaction units are feasible. The components of the cassette are suited to mass production and robotic assembly to produce a readily manufactured disposable reaction cassette that can be configured for disease-specific testing panels. Rapid testing with a disposable reaction cassette on an inexpensive instrument will permit on the spot evaluation of patients in the clinic for faster medical decision-making and more informed therapeutic choices

Objective assessment of stored blood quality by deep learning

Stored red blood cells (RBCs) are needed for life-saving blood transfusions, but they undergo continuous degradation. RBC storage lesions are often assessed by microscopic examination or biochemical and biophysical assays, which are complex, time-consuming, and destructive to fragile cells. Here we demonstrate the use of label-free imaging flow cytometry and deep learning to characterize RBC lesions. Using brightfield images, a trained neural network achieved 76.7% agreement with experts in classifying seven clinically relevant RBC morphologies associated with storage lesions, comparable to 82.5% agreement between different experts. Given that human observation and classification may not optimally discern RBC quality, we went further and eliminated subjective human annotation in the training step by training a weakly supervised neural network using only storage duration times. The feature space extracted by this network revealed a chronological progression of morphological changes that better predicted blood quality, as measured by physiological hemolytic assay readouts, than the conventional expert-assessed morphology classification system. With further training and clinical testing across multiple sites, protocols, and instruments, deep learning and label-free imaging flow cytometry might be used to routinely and objectively assess RBC storage lesions. This would automate a complex protocol, minimize laboratory sample handling and preparation, and reduce the impact of procedural errors and discrepancies between facilities and blood donors. The chronology-based machine-learning approach may also improve upon humans’ assessment of morphological changes in other biomedically important progressions, such as differentiation and metastasis

Investigating Instructor Talk in Novel Contexts: Widespread Use, Unexpected Categories, and an Emergent Sampling Strategy.

Instructor Talk-noncontent language used by instructors in classrooms-is a recently defined and promising variable for better understanding classroom dynamics. Having previously characterized the Instructor Talk framework within the context of a single course, we present here our results surrounding the applicability of the Instructor Talk framework to noncontent language used by instructors in novel course contexts. We analyzed Instructor Talk in eight additional biology courses in their entirety and in 61 biology courses using an emergent sampling strategy. We observed widespread use of Instructor Talk with variation in the amount and category type used. The vast majority of Instructor Talk could be characterized using the originally published Instructor Talk framework, suggesting the robustness of this framework. Additionally, a new form of Instructor Talk-Negatively Phrased Instructor Talk, language that may discourage students or distract from the learning process-was detected in these novel course contexts. Finally, the emergent sampling strategy described here may allow investigation of Instructor Talk in even larger numbers of courses across institutions and disciplines. Given its widespread use, potential influence on students in learning environments, and ability to be sampled, Instructor Talk may be a key variable to consider in future research on teaching and learning in higher education
