Leveraging Thousands of Contrail Observations from GLOBE Citizen Scientists

The GLOBE (Global Learning and Observations to Benefit the Environment) Program is NASA's largest and longest-operating citizen science program contributing Earth observations. Over 800,000 cloud observations have been reported worldwide since YEAR that include reports of short-lived, persistent, and persistent-spreading contrails. While contrails can be challenging to observe with space-borne platforms, humans are adept at spotting contrails from the ground. The NASA GLOBE Clouds team at NASA Langley Research Center in Hampton, Virginia matches cloud observations to multiple satellite platforms for comparison, including: NASA's CERES (Clouds and Earth's Radiant Energy System) instrument onboard Terra and Aqua, CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation), and geostationary satellites. A pilot project was started with select students in the United States to track airplanes above 25,000 ft and report airplane type, altitude, and report if a contrail was being or was not being produced. The objective of the pilot project was to establish if this is a scalable approach for building an international observational dataset documenting what types of airplanes are creating what types of contrails (short-lived, persistent, spreading) under what atmospheric conditions. Preliminary results of this pilot project will be presented

'A kinder sort of contract': A research study with the Migrants Resource Centre in London looking at holistic service provision

The aim of this small-scale study was to examine the range of the Migrants Resource Centre's provision and activities and to explore the effect and impact on the lives of immigrants who have used the centre. The study particularly focused on the education and employment support service

Tuberculosis in Dr Granville's mummy: a molecular re-examination of the earliest known Egyptian mummy to be scientifically examined and given a medical diagnosis

‘Dr Granville's mummy’ was described to the Royal Society of London in 1825 and was the first ancient Egyptian mummy to be subjected to a scientific autopsy. The remains are those of a woman, Irtyersenu, aged about 50, from the necropolis of Thebes and dated to about 600 BC. Augustus Bozzi Granville (1783–1872), an eminent physician and obstetrician, described many organs still in situ and attributed the cause of death to a tumour of the ovary. However, subsequent histological investigations indicate that the tumour is a benign cystadenoma. Histology of the lungs demonstrated a potentially fatal pulmonary exudate and earlier studies attempted to associate this with particular disease conditions. Palaeopathology and ancient DNA analyses show that tuberculosis was widespread in ancient Egypt, so a systematic search for tuberculosis was made, using specific DNA and lipid biomarker analyses. Clear evidence for Mycobacterium tuberculosis complex DNA was obtained in lung tissue and gall bladder samples, based on nested PCR of the IS6110 locus. Lung and femurs were positive for specific M. tuberculosis complex cell-wall mycolic acids, demonstrated by high-performance liquid chromatography of pyrenebutyric acid–pentafluorobenzyl mycolates. Therefore, tuberculosis is likely to have been the major cause of death of Irtyersenu

Characterisation and Germline Transmission of Cultured Avian Primordial Germ Cells

Background: Avian primordial germ cells (PGCs) have significant potential to be used as a cell-based system for the study and preservation of avian germplasm, and the genetic modification of the avian genome. It was previously reported that PGCs from chicken embryos can be propagated in culture and contribute to the germ cell lineage of host birds. Principal Findings: We confirm these results by demonstrating that PGCs from a different layer breed of chickens can be propagated for extended periods in vitro. We demonstrate that intracellular signalling through PI3K and MEK is necessary for PGC growth. We carried out an initial characterisation of these cells. We find that cultured PGCs contain large lipid vacuoles, are glycogen rich, and express the stem cell marker, SSEA-1. These cells also express the germ cell-specific proteins CVH and CDH. Unexpectedly, using RT-PCR we show that cultured PGCs express the pluripotency genes c-Myc, cKlf4, cPouV, cSox2, and cNanog. Finally, we demonstrate that the cultured PGCs will migrate to and colonise the forming gonad of host embryos. Male PGCs will colonise the female gonad and enter meiosis, but are lost from the gonad during sexual development. In male hosts, cultured PGCs form functional gametes as demonstrated by the generation of viable offspring. Conclusions: The establishment of in vitro cultures of germline competent avian PGCs offers a unique system for the study of early germ cell differentiation and also a comparative system for mammalian germ cell development. Primary PGC lines will form the basis of an alternative technique for the preservation of avian germplasm and will be a valuable tool fo

Pilot service evaluation of a brief psychological therapy for self-harm in an emergency department: Hospital Outpatient Psychotherapy Engagement Service

© 2020 The Authors. Psychology and Psychotherapy: Theory, Research and Practice published by John Wiley & Sons Ltd on behalf of British Psychological Society Background: Brief psychological therapies may be helpful for people who have recently self-harmed. The current paper reports on a service evaluation of a novel brief therapy service based within an Emergency Department, Hospital Outpatient Psychotherapy Engagement (HOPE) Service. This service combines elements of psychodynamic interpersonal and cognitive analytic therapy to help people who present with self-harm-related difficulties. The primary aim of this service evaluation was to ascertain the feasibility of HOPE in terms of attendance rates. The study also examined variables associated with engagement, and change over time in psychological distress for those attending the service. Method: The HOPE service was evaluated over a ten-month period. Consenting patients completed measures of psychological distress and working alliance across four therapy sessions and one follow-up session. Measures of emotion regulation style and self-harm function were also completed at the point of referral. Results: Eight-nine patients were referred to the service (83 eligible referrals). Fifty-three (64%) attended at least one therapy session. Baseline variables did not distinguish people who attended and people who did not. Psychological distress decreased significantly across the sessions. Most people reported a good working alliance with their therapist. Conclusions: The results of this service evaluation support the feasibility of the HOPE service, demonstrating good engagement rates given the complexity of the population and context. Whilst there was evidence of reductions in distress, randomized controlled trials are needed to determine if HOPE has clinical efficacy. Practitioner points: Rates of engagement with HOPE suggest the service is feasible in an Emergency Department context Working alliance scores were positive for the majority of patients The HOPE service shows promise as a brief intervention for people who self-harm but requires further evaluation Randomized controlled trials are needed to determine the clinical efficacy of the HOPE service

Supporting service change in palliative care: a framework approach

Copyright 2014 Mark Allen Healthcare. editorially accepted manuscript version of the paper reproduced here with permission from the publisher.Background Palliative care services are increasingly identifying areas for improvement, then trying to create appropriate changes in response. Nurses in particular are often expected to take leading roles in Quality Improvement (QI) but are not necessarily trained or supported in these processes. Methods. A framework approach to change was developed to guide services through a change cycle, and delivered via workshops by representatives of three national projects in Australia. Participants were predominantly nurses (80%) with the majority over the age of 50 (62.4%). The workshops and the framework were positively evaluated with participants feeling confident in a number of QI related activities following workshop training. Discussion. Recognising and addressing problems in clinical practice and service delivery is an important way for nurses to ensure quality care for patients, however, they need support in developing the skills and knowledge that are essential to successful QI activities
