Conceptual framework for living with and beyond cancer: A systematic review and narrative synthesis.

OBJECTIVE: The concept of living with and beyond cancer is now emerging in policy and literature. Rather than viewing this notion simply as a linear timeline, developing an agreed understanding of the lived experience of people affected by cancer will aid the development of person-centred models of care. METHODS: A systematic review was conducted. The review question was "What does the term 'living with and beyond cancer' mean to people affected by cancer?" The protocol for the review was preregistered in the PROSPERO database (PROSPERO CRD42017059860). All included studies were qualitative, so narrative synthesis was used to integrate descriptions and definitions of living with and beyond cancer into an empirically based conceptual framework. RESULTS: Out of 2345 papers that were identified and 180 that were reviewed, a total of 73 papers were included. The synthesis yielded three interlinked themes: Adversity (realising cancer), Restoration (readjusting life with cancer), and Compatibility (reconciling cancer), resulting in the ARC framework. CONCLUSIONS: Three themes describe the experience of living with and beyond cancer: adversity, restoration, and compatibility. The ARC framework provides an empirically informed grounding for future research and practice in supportive cancer care for this population

Neurogenic switching: a hypothesis for a mechanism for shifting the site of inflammation in allergy and chemical sensitivity.

Neurogenic switching is proposed as a hypothesis for a mechanism by which a stimulus at one site can lead to inflammation at a distant site. Neurogenic inflammation occurs when substance P and other neuropeptides released from sensory neurons produce an inflammatory response, whereas immunogenic inflammation results from the binding of antigen to antibody or leukocyte receptors. There is a crossover mechanism between these two forms of inflammation. Neurogenic switching is proposed to result when a sensory impulse from a site of activation is rerouted via the central nervous system to a distant location to produce neurogenic inflammation at the second location. Neurogenic switching is a possible explanation for systemic anaphylaxis, in which inoculation of the skin or gut with antigen produces systemic symptoms involving the respiratory and circulatory systems, and an experimental model of anaphylaxis is consistent with this hypothesis. Food-allergy-iducing asthma, urticaria, arthritis, and fibromyalgia are other possible examples of neurogenic switching. Neurogenic switching provides a mechanism to explain how allergens, infectious agents, irritants, and possibly emotional stress can exacerbate conditions such as migraine, asthma, and arthritis. Because neurogenic inflammation is known to be triggered by chemical exposures, it may play a role in the sick building syndrome and the multiple chemical sensitivity syndrome. Thus neurogenic switching would explain how the respiratory irritants lead to symptoms at other sites in these disorders

Driver discomfort in vehicle seats – Effect of changing road conditions and seat foam composition

This article was published in the journal Applied Ergonomics [© Elsevier] and the definitive version is available at: http://dx.doi.org/10.1016/j.apergo.2015.03.010Discomfort in vehicle seats is a multi-factorial problem with contributions occurring from effects of sitting duration, seat design, and the dynamic environment to which the occupant is exposed. This paper reports laboratory studies investigating the extent to which reports of discomfort are affected by vibration commencing or ceasing, and whether methods of assessment are sensitive enough to detect small changes in foam composition. Study 1 measured discomfort ratings for two conditions of 60 minutes each, comprising 30 minutes of vibration exposure followed by 30 minutes of static sitting in a car seat, and vice-versa. Study 2 measured discomfort ratings for three conditions over a period of 40 minutes each, whilst participants were sitting in one of two car seat compositions, and either exposed to vibration or not. In both studies participants operated a driving simulator. It is shown that exposure to vibration increases the rate of discomfort onset in comparison to periods of static sitting. When vibration stopped, there was an acute improvement in comfort but discomfort did not drop to the levels reported by those who had been unexposed. When vibration started after 30 minutes of static sitting, there was an acute increase in discomfort but not to the levels reported by those who had been exposed to 30 minutes of vibration. After 40 minutes of continuous exposure it was possible to detect significant differences in overall discomfort between the two seat compositions, although trends could be observed in less time

A BRiTE Journey: 2013–2019

Resilience is widely acknowledged as important for teacher success, yet how to assist pre-service teachers build the skills and strategies for professional resilience is a question often asked by teacher educators. This chapter overviews the design, development and features of a series of five online learning modules designed to support pre-service teacher resilience. The BRiTE modules were informed by an analysis of the literature and content created to address the key themes. Five modules were developed: Building resilience, Relationships, Wellbeing, Taking initiative and Emotions. Each module was designed to be interactive and personalised, enabling users to build their personal toolkit to support their resilience. Since their launch in 2015, the modules have been widely used by pre-service teachers, teachers and a range of stakeholders with over 14,000 registered users at the beginning of 2020. Potential for future use in supporting teacher resilience is discussed

Diet restriction in migraine, based on IgG against foods: A clinical double-blind, randomised, cross-over trial

Introduction: It is well-known that specific foods trigger migraine attacks in some patients. We aimed to investigate the effect of diet restriction, based on IgG antibodies against food antigens on the course of migraine attacks in this randomised, double blind, cross-over, headache-diary based trial on 30 patients diagnosed with migraine without aura

‘Still living with it even though it's gone’: Using interpretive phenomenological analysis to explore shared experiences of living with and beyond breast, prostate, and colorectal cancer

© 2021 The Authors. Purpose Living with and beyond cancer is an increasingly common experience. While research is uncovering valuable individual experiences of those living with and beyond cancer, it has been argued that this idiographic approach is limited in outlook, reach and impact. This study contributes to the understanding of what it means to live with and beyond cancer by complementing idiographic knowledge with multiple perspectives from a group of participants who are living with and beyond cancer, to explore how individual experiences may be relevant to others. Method Semi-structured interviews were conducted with people who had received treatment for breast (n = 6), prostate (n = 6) or colorectal cancer (n = 6). Data were analysed using interpretive phenomenological analysis. The early findings were then shared with a wider group of people who had received treatment for breast, prostate or colorectal cancer (n = 26) in six focus groups, to explore whether they had similar experiences. Results While individual accounts of living with and beyond cancer detail unique features specific to each person's experience, focus group discussions illustrated how participant life worlds interact and overlap. The findings identified thematic similarities within and between individual and group levels and across cancer types. Three super-ordinate themes describe the shared experience of living with and beyond cancer: i) the cancer shock, ii) managing cancer and getting through and iii) getting over cancer. Conclusions A multiple perspective approach informs our understanding of shared experiences of living with and beyond cancer. This knowledge can be used to direct, design, and deliver relevant supportive cancer care.Macmillan cancer support

Exon Exchange Approach to Repair Duchenne Dystrophin Transcripts

Background: Trans-splicing strategies for mRNA repair involve engineered transcripts designed to anneal target mRNAs in order to interfere with their natural splicing, giving rise to mRNA chimeras where endogenous mutated exons have been replaced by exogenous replacement sequences. A number of trans-splicing molecules have already been proposed for replacing either the 59 or the 39 part of transcripts to be repaired. Here, we show the feasibility of RNA surgery by using a double trans-splicing approach allowing the specific substitution of a given mutated exon. Methodology/Principal Findings: As a target we used a minigene encoding a fragment of the mdx dystrophin gene enclosing the mutated exon (exon 23). This minigene was cotransfected with a variety of exon exchange constructions, differing in their annealing domains. We obtained accurate and efficient replacement of exon 23 in the mRNA target. Adding up a downstream intronic splice enhancer DISE in the exon exchange molecule enhanced drastically its efficiency up to 25–45 % of repair depending on the construction in use. Conclusions/Significance: These results demonstrate the possibility to fix up mutated exons, refurbish deleted exons and introduce protein motifs, while keeping natural untranslated sequences, which are essential for mRNA stability and translation regulation. Conversely to the well-known exon skipping, exon exchange has the advantage to be compatible with almost any type of mutations and more generally to a wide range of genetic conditions. In particular, it allows addressing disorders caused by dominant mutations

Quietly sharing the load? The role of school psychologists in enabling teacher resilience

Teacher resilience is associated with positive student outcomes and plays an important role in teacher retention and well-being. School ecologies can enable the resilience of teachers, with prior research illustrating the importance of supportive colleagues, strong leadership, and positive school culture. There is limited research, however, exploring the role of school psychologists in supporting or enabling teacher resilience. Using data from experienced Australian school psychologists and teachers, this exploratory qualitative study examines the role of school psychologists in enabling teacher resilience. Findings show that school psychologists directly and indirectly support teacher resilience, although teachers perceive school psychologists’ main role as work with individual students. Issues pertaining to variations in access and particular roles of school psychologists are discussed. Although further research is needed to clarify and promote the role of school psychologists, this study points to them potentially playing an important role in school ecologies that enable teacher resilience

Perceval: A Software Platform for Discrete Variable Photonic Quantum Computing

We introduce Perceval, an evolutive open-source software platform for simulating and interfacing with discrete variable photonic quantum computers, and describe its main features and components. Its Python front-end allows photonic circuits to be composed from basic photonic building blocks like photon sources, beam splitters, phase shifters and detectors. A variety of computational back-ends are available and optimised for different use-cases. These use state-of-the-art simulation techniques covering both weak simulation, or sampling, and strong simulation. We give examples of Perceval in action by reproducing a variety of photonic experiments and simulating photonic implementations of a range of quantum algorithms, from Grover's and Shor's to examples of quantum machine learning. Perceval is intended to be a useful toolkit both for experimentalists wishing to easily model, design, simulate, or optimise a discrete variable photonic experiment, and for theoreticians wishing to design algorithms and applications for discrete-variable photonic quantum computing platforms
