Mental Health Awareness Building via Android Application

The goal of this project was to create a tool that provides students at Minnesota State University, Mankato with mental health information through a freely available smartphone application (App). Our approach used a software engineering design process that focused on who our customers are, what resources are available, and how we can best connect the two to improve student lives. We identified the stakeholders involved and worked with campus mental health professionals to help shape our App. While there is a broad range of mental health topics, we have focused on materials related to depression. The first process of the App gives the student a picture of their current mental health state through a frequently used and freely available evaluation questionnaire. Depending on the results, the App then provides supportive feedback in the form of materials that describe coping skills, ways to contact campus counselors, and other local community resources. In addition, we have incorporated formal graphic design to make the App easy to use. The outcome of this work is an App that is free for campus students, connects them to resources and can be improved upon by future developers. As part of future work we plan to incorporate artificial intelligence approaches to provide the most appropriate materials given the student evaluation

Characteristics and incidence of transfusion-associated necrotizing enterocolitis in the UK

BACKGROUND AND AIMS: The etiology of necrotizing enterocolitis (NEC) is unclear and postulated as being multifactorial. It has been suggested that one causative factor is the transfusion of packed red blood cells (PRBCs) leading to the disease entity commonly referred to as transfusion-associated NEC (TANEC). TANEC has been reported in North America but its incidence has not been formally investigated in the UK. Our aims were to identify the incidence of NEC and TANEC in tertiary-level UK neonatal units and to describe characteristics of TANEC cases. MATERIALS AND METHODS: Using strict case definitions for NEC and TANEC, we undertook a retrospective review to estimate the incidence of TANEC cases occurring in four UK tertiary-level centers during a 38-month period. RESULTS: Of 8007 consecutive neonatal admissions of all gestations to the four centers, 68 babies went on to develop NEC and all affected infants were of very low birth weight (VLBW); 34 of these had previously received a transfusion of PRBCs but did not fit the diagnostic criteria for TANEC, whereas 15 (22%) of the 68 babies with NEC qualified as TANEC cases. UK cases occurred at an earlier postnatal age than cases reported in multiple large North American series and were of a lower birth weight. CONCLUSIONS: We have confirmed the presence of TANEC in the UK VLBW neonatal population. Its incidence lies within the wide range described in previous reports of this phenomenon globally, though with some local variation in characteristics. Further work is needed to clarify causation, pathophysiology, and possible mechanisms of prevention of TANEC

The Effects of Temperature on Clot Microstructure and Strength in Healthy Volunteers

BACKGROUND: Anesthesia, critical illness, and trauma are known to alter thermoregulation, which can potentially affect coagulation and clinical outcome. This in vitro preclinical study explores the relationship between temperature change and hemostasis using a recently validated viscoelastic technique. We hypothesize that temperature change will cause significant alterations in the microstructural properties of clot. METHODS: We used a novel viscoelastic technique to identify the gel point of the blood. The gel point identifies the transition of the blood from a viscoelastic liquid to a viscoelastic solid state. Furthermore, identification of the gel point provides 3 related biomarkers: the elastic modulus at the gel point, which is a measure of clot elasticity; the time to the gel point (TGP), which is a measure of the time required to form the clot; and the fractal dimension of the clot at the gel point, df, which quantifies the microstructure of the clot. The gel point measurements were performed in vitro on whole blood samples from 136 healthy volunteers over a temperature range of 27°C to 43°C. RESULTS: There was a significant negative correlation between increases in temperature, from 27°C to 43°C, and TGP (r = −0.641, P 37°C. CONCLUSIONS: This study demonstrates that the gel point technique can identify alterations in clot microstructure because of changes in temperature. This was demonstrated in slower-forming clots with less structural complexity as temperature is decreased. We also found that significant changes in clot microstructure occurred when the temperature was ≤32°C

A common supersolid low-density skin sliperizing ice and toughening water surface

Skins of water and ice share the same attribute of supersolidity characterized by the identical H-O vibration frequency of 3450 cm-1. Molecular undercoordination and inter-electron-pair repulsion shortens the H-O bond and lengthen the O:H nonbond, leading to a dual process of nonbonding electron polarization. This relaxation-polarization process enhances the dipole moment, elasticity,viscosity, thermal stability of these skins with 25% density loss, which is responsible for the hydrophobicity and toughness of water skin and for the slippery of ice.Comment: arXiv admin note: text overlap with arXiv:1401.804

The state of professional practice and policy in the English further education system: a view from below

This paper addresses a recurring theme regarding the UK’s Vocational Education and Training (VET) policy in which Further Education (FE) and training are primarily driven by employer demand. It explores the tensions associated with this process on the everyday working practices of FE practitioners and institutions and its impact on FE’s contribution to the wider processes of social and economic inclusion. At a time when Ofsted and employer-led organisations have cast doubt on the contribution of FE, we explore pedagogies of practice that are often unacknowledged by the current audit demands of officialdom. We argue that such practice provides a more enlightened view of the sector and the challenges it faces in addressing wider issues of social justice, employability and civic regeneration. At the same time, the irony of introducing laissez-faire initiatives designed to remove statutory qualifications for FE teachers ignores the progress made over the past decade in raising the professional profile and status of teachers and trainers in the sector. In addressing such issues, the paper explores the limits and possibilities of constructing professional and vocational knowledge from networks and communities of practice, schools, universities, business, employers and local authorities, in which FE already operates

Platelet-Related Variants Identified by Exomechip Meta-analysis in 157,293 Individuals

Platelet production, maintenance, and clearance are tightly controlled processes indicative of platelets important roles in hemostasis and thrombosis. Platelets are common targets for primary and secondary prevention of several conditions. They are monitored clinically by complete blood counts, specifically with measurements of platelet count (PLT) and mean platelet volume (MPV). Identifying genetic effects on PLT and MPV can provide mechanistic insights into platelet biology and their role in disease. Therefore, we formed the Blood Cell Consortium (BCX) to perform a large-scale meta-analysis of Exomechip association results for PLT and MPV in 157,293 and 57,617 individuals, respectively. Using the low-frequency/rare coding variant-enriched Exomechip genotyping array, we sought to identify genetic variants associated with PLT and MPV. In addition to confirming 47 known PLT and 20 known MPV associations, we identified 32 PLT and 18 MPV associations not previously observed in the literature across the allele frequency spectrum, including rare large effect (FCER1A), low-frequency (IQGAP2, MAP1A, LY75), and common (ZMIZ2, SMG6, PEAR1, ARFGAP3/PACSIN2) variants. Several variants associated with PLT/MPV (PEAR1, MRVI1, PTGES3) were also associated with platelet reactivity. In concurrent BCX analyses, there was overlap of platelet-associated variants with red (MAP1A, TMPRSS6, ZMIZ2) and white (PEAR1, ZMIZ2, LY75) blood cell traits, suggesting common regulatory pathways with shared genetic architecture among these hematopoietic lineages. Our large-scale Exomechip analyses identified previously undocumented associations with platelet traits and further indicate that several complex quantitative hematological, lipid, and cardiovascular traits share genetic factors

Applications of electrified dust and dust devil electrodynamics to Martian atmospheric electricity

Atmospheric transport and suspension of dust frequently brings electrification, which may be substantial. Electric fields of 10 kVm-1 to 100 kVm-1 have been observed at the surface beneath suspended dust in the terrestrial atmosphere, and some electrification has been observed to persist in dust at levels to 5 km, as well as in volcanic plumes. The interaction between individual particles which causes the electrification is incompletely understood, and multiple processes are thought to be acting. A variation in particle charge with particle size, and the effect of gravitational separation explains to, some extent, the charge structures observed in terrestrial dust storms. More extensive flow-based modelling demonstrates that bulk electric fields in excess of 10 kV m-1 can be obtained rapidly (in less than 10 s) from rotating dust systems (dust devils) and that terrestrial breakdown fields can be obtained. Modelled profiles of electrical conductivity in the Martian atmosphere suggest the possibility of dust electrification, and dust devils have been suggested as a mechanism of charge separation able to maintain current flow between one region of the atmosphere and another, through a global circuit. Fundamental new understanding of Martian atmospheric electricity will result from the ExoMars mission, which carries the DREAMS (Dust characterization, Risk Assessment, and Environment Analyser on the Martian Surface)-MicroARES (Atmospheric Radiation and Electricity Sensor) instrumentation to Mars in 2016 for the first in situ measurements
