RESUMO
Low- and middle-income countries are increasingly faced with a triple burden of malnutrition: endemic underweight, micronutrient deficiencies and rising prevalence of overweight. This study aimed to address existing knowledge gaps and to identify priority policy options in Mongolia, the Philippines and Vietnam. A landscape analysis approach was adopted using methods set out in a UNICEF global toolkit. Quantitative and qualitative data were compiled from a range of global and national sources on childhood overweight and obesity, risk factors and policy responses. Key informant interviews and validation workshops were undertaken with key food and nutrition stakeholders from government and non-government organizations to identify priority policy options for the prevention of overweight and obesity among children. Overweight and obesity among children are increasing in all three countries. Associated risk factors are related to maternal nutrition, birthweight, breastfeeding, as well as diets and physical activity shaped by increasingly obesogenic environments. Key informants identified undefined policy approaches, poor community understanding and food and beverage industry influence as barriers to addressing overweight and obesity. Key policy priorities include restricting the marketing of unhealthy food and beverages, unhealthy food and beverage taxation, introduction of front-of-pack nutrition labels and improving school nutrition environments. Mongolia, the Philippines and Vietnam are all facing an increasing burden of childhood overweight and obesity. Despite differing national contexts, similar environmental factors are driving this rise. A suite of evidence-based policies can effectively be introduced to address obesogenic environments.

OBJECTIVE: To prioritise policy actions for government to improve the food environment and contribute to reduced obesity and related diseases. DESIGN: Cross-sectional study applying the Food Environment Policy Index (Food EPI) in two stages. First, the evidence on all relevant policies was compiled, through an Internet search of government documents, and reviewed for accuracy and completeness by government officials. Second, independent experts were brought together to identify critical gaps and prioritise actions to fill those gaps, through a two-stage rating process. SETTING: England. SUBJECTS: A total of seventy-three independent experts from forty-one organisations were involved in the exercise. RESULTS: The top priority policy actions for government identified were: (i) control the advertising of unhealthy foods to children; (ii) implement the levy on sugary drinks; (iii) reduce the sugar, fat and salt content in processed foods (leading to an energy reduction); (iv) monitor school and nursery food standards; (v) prioritise health and the environment in the 25-year Food and Farming Plan; (vi) adopt a national food action plan; (vii) monitor the food environment; (viii) apply buying standards to all public institutions; (ix) strengthen planning laws to discourage less healthy food offers; and (x) evaluate food-related programmes and policies. CONCLUSIONS: Applying the Food EPI resulted in agreement on the ten priority actions required to improve the food environment. The Food EPI has proved to be a useful tool in developing consensus for action to address the obesity epidemic among a broad group of experts in a complex legislative environment.

Background Pilot studies are more commonly associated with quantitative research, and their use is under-reported in qualitative approaches. This paper discusses the value of undertaking a pilot study in a doctoral research project to examine nursing students' understanding of recovery in mental health by adopting what is called a phenomenographic approach, which in research is concerned with the variation in how particular phenomena are experienced. Aim To explore the usefulness of three different methods of collecting data - interviewing, completed exam papers and a written response to a scenario - and the Dahlgren and Fallsberg ( 1991 ) framework for phenomenographic data analysis. Discussion Methodological issues experienced during the collection and analysis of data in the project are discussed. Conclusion The pilot study provided an opportunity for valuable insights to be gained into the methodological issues related to phenomenography and to revise the research plan for the larger study. Implications for practice While it may not be generalised to other qualitative studies, this paper may help others undertaking studies that adopt this approach and points to the general value of pilot studies in qualitative research.

Noticing is integral to the everyday practice of nurses; it is the pre-cursor for clinical reasoning, informing judgement and the basis of care. By noticing the nurse can pre-empt possible risks or support subtle changes towards recovery. Noticing can be the activity that stimulates action before words are exchanged, pre-empting need. In this article, the art of noticing is explored in relation to nursing practice and how the failure to notice can have serious consequences for those in care.

AIM: To understand the experiences of transition from the perspective of newly qualified mental health nurses and the impact this may have on their potential to remain in the role. BACKGROUND: During the transitional period following registration newly qualified nurses experience feelings of being overwhelmed and shock. Internationally there is limited research on factors influencing transitional experiences in the field of mental health. DESIGN: A qualitative exploration was conducted using thematic content analysis to analyse the data gathered from semi-structured interviews METHOD: 18 Newly qualified mental health nurses from two NHS Mental Health trusts were interviewed, all within 18 months of registration. Data were analysed and themes generated addressing the research aim. RESULTS/FINDINGS: Five themes were co-created using this inductive technique: 'Transition to new role', 'Support for new role', 'Professional identity', 'Role development' and 'Working environment'. These themes are representative headings with the sub-themes making up the contributory content. Themes highlighted issues concerning newly qualified nurses and the transition which included aspects of anxiety and feeling overwhelmed initially. This highlighted the feelings associated with transition and progression through the process of liminality. Supervision was identified in the context of formal support, the presence of which is conducive to a positive transition. Imposter syndrome and experiencing reality shock were common aspects of role development and acknowledging the sense of responsibility gained once registered. Safety was highlighted as many experienced their first role on in-patient environments which was busy and potentially hostile. CONCLUSION: The transition of newly qualified nurses in mental health services can prove to be a difficult experience, therefore it requires acknowledgment and careful consideration. Understanding the liminal process may allow staff to appreciate the effect of the transition and to understand that the NQN will face overwhelming and unfamiliar responsibilities. Despite the demands to boost the workforce in mental health services there is a need to understand how best to integrate NQN's into their role during this transition. Caution must be used if we are not to lose more NQN's, as despite concerns there are still NQN's looking to mental health nursing as their future and chosen career.
RESUMO
Recent technical advances provide the ability to isolate and purify mRNAs from genetically distinct cell types so as to provide a broader view of gene expression as they relate to gene networks. These tools allow the genome of organisms undergoing different developmental or diseased states and environmental or behavioral conditions to be compared. Translating ribosome affinity purification (TRAP), a method using transgenic animals expressing a ribosomal affinity tag (ribotag) that targets ribosome-bound mRNAs, allows for the rapid isolation of genetically distinct populations of cells. In this chapter, we provide stepwise methods for carrying out an updated protocol for using the TRAP method in the South African clawed frog Xenopus laevis. A discussion of the experimental design and necessary controls and their rationale, along with a description of the bioinformatic steps involved in analyzing the Xenopus laevis translatome using TRAP and RNA-Seq, is also provided.

Many human optic neuropathies lead to crippling conditions resulting in partial or complete loss of vision. While the retina is made up of several different cell types, retinal ganglion cells (RGCs) are the only cell type connecting the eye to the brain. Optic nerve crush injuries, wherein RGC axons are damaged without severing the optic nerve sheath, can serve as a model for traumatic optical neuropathies as well as some progressive neuropathies such as glaucoma. In this chapter, we describe two different surgical methods for establishing an optic nerve crush (ONC) injury in the postmetamorphic frog, Xenopus laevis. Why use the frog as an animal model? Mammals lose the ability to regenerate damaged CNS neurons, but amphibians and fish retain the ability to regenerate new RGC bodies and regrow RGC axons following an injury. In addition to presenting two different surgical ONC injury methods, we highlight their advantages and disadvantages and discuss the distinctive characteristics of Xenopus laevis as an animal model for studying CNS regeneration.

WHAT IS KNOWN ON THE SUBJECT?: Risk assessment and risk management are considered to be important practices carried out by mental health nurses. Risk assessment can help keep mental health service users' safe, but some nurses see it as a 'tick the box' exercise. Some studies have looked at nurses' attitudes to risk assessment but no one has systematically described all the studies. WHAT THE ARTICLE ADDS TO EXISTING KNOWLEDGE?: Mental health nurses' attitudes towards risk assessment are diverse with regard to its legitimacy, conduct and value. This study provides an organised framework to help understand the areas in which these different attitudes occur. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Since attitudes can influence clinical practice, nurses need to reflect on how they view risk assessment. Further research is required to investigate whether particular attitudes are positive or negative and whether attitudes can be changed. ABSTRACT: INTRODUCTION: Understanding nurses' attitudes towards risk assessment could inform education and practice improvements. AIM/QUESTION: To explore mental health nurses' attitudes towards risk assessment. METHOD: An integrative systematic review (PROSPERO: CRD42023398287). Multiple databases (PubMed, CINAHL, MEDLINE, EMBASE and PsycINFO) were searched for primary studies of mental health nurses' attitudes towards risk assessment. Qualitative studies were subject to inductive coding and thematic analysis; quantitative data were integrated with emerging themes. RESULTS: Eighteen articles were included. Qualitative studies commonly lacked rigorous analyses. Four themes emerged: underlying purpose and legitimacy of risk assessment (philosophical orientation); use of structured approaches (technical orientation); value of intuition (intuitive orientation); and service user involvement (relationships orientation). There were contradictory study findings in each thematic category indicating different attitudes among mental health nurses. DISCUSSION: Mental health nurses' attitudes towards risk assessment vary in four key domains. Survey studies suggest they are more approving of structured approaches to risk assessment than many qualitative studies suggest. There is a need to develop a valid measure of attitudes to risk assessment. IMPLICATIONS FOR PRACTICE: This review could help health organisations to develop strategies to improve their risk assessment policies and practice. There is a need to develop structured training and education programmes.

CNS injuries of the anuran amphibian, Xenopus laevis, are uniquely suited for studying the molecular compositions of neuronal regeneration of retinal ganglion cells (RGC) due to a functional recovery of optic axons disparate to adult mammalian analogues. RGCs and their optic nerve axons undergo irreversible neurodegeneration in glaucoma and associated optic neuropathies, resulting in blindness in mammals. Conversely, Xenopus demonstrates RGC lifetime-spanning regenerative capabilities after optic nerve crush [1], inciting opportunities to compare de novo regeneration and develop efficient pharmaceutical approaches for vision restoration. Studies revealing lipidome alterations during optic nerve regeneration are sparse and could serve as a solid foundation for these underlying molecular changes. We profile the lipid changes in a transgenic line of 1 year old Xenopus laevis Tg(islet2b:gfp) frogs that were either left untreated (naïve) or had a monocular surgery of either a left optic crush injury (crush) or sham surgery (sham). Matching controls of uninjured right optic nerves were also collected (control). Tg(islet2b:gfp) frogs were allowed to recover for 7,12,18, and 27 days post optic nerve crush. Following euthanasia, the optic nerves were collected for lipidomic analysis. A modified Bligh and Dyer method [2] was used for lipid extraction, followed by untargeted mass spectrometry lipid profiling with a Q Exactive Orbitrap Mass Spectrometer coupled with a Vanquish Horizon Binary UHPLC LC-MS system (LC MS-MS). The raw scans were analyzed and quantified with LipidSearch 5.0 and the statistical analysis was conducted through Metaboanalyst 5.0. This data is available at Metabolomics Workbench, study ID [ST002414].
RESUMO
BACKGROUND: Fluid injection pressure measurement is promoted as a marker of needle tip position that discriminates between tissue layers. However, clinical ultrasound has insufficient resolution to identify the exact position of the needle tip. Our primary objective was to use 40 MHz ultrasound in anesthetized pigs in order to precisely locate the tip of the needle and measure opening injection pressure in muscle, at epineurium and in subepineurium. METHODS: We surgically exposed the axillae of four anesthetized pigs. Two operators placed a 40 MHz ultrasound transducer over the pectoral muscle and imaged axillary, median and radial nerves. Injections (0.5 mL) were randomized to in-plane and out-of-plane needle trajectories and flow rates of 1, 6 and 12 mL/min. RESULTS: We identified 541 fascicles in 23 nerves. The ratio of fascicle area to nerve area remained constant at ~0.30 for all nerves. Axillary nerves were smaller than median and radial nerves, difference in diameter (95% CI) 1.61 (0.87 to 2.36) mm, p<0.001 and 1.59 (0.82 to 2.36) mm, p=0.001, respectively. Axillary nerves had less fascicles per nerve than median nerves, difference 7.63 (2.43 to 12.83) and radial nerves, difference 9.02 (3.64 to 14.40). We visualized the circumneurium and injection within the subcircumneural compartment. Intraneural injection increased nerve area (SD) from 5.7 (2.2) mm2 to 13.7 (5.5) mm2, difference 8.0 (5.4-10.6) mm2, p<0.001. Mean injection pressure was greater in subepineurium compared with muscle, geometric ratio 2.29 (1.30 to 4.10), p<0.001; and greater on epineurium compared with muscle, geometric ratio 1.73 (1.03 to 3.00), p=0.01. Twenty-two out of 23 injections in muscle, 14 out of 23 injections at epineurium and 11 out of 22 injections in subepineurium were <138 kPa (20 psi). CONCLUSION: Needle tip position was not discernible using pressure monitoring. The circumneurium and subcircumneural injection compartment were observed but not intrafascicular injection.

OBJECTIVE: To determine which interventions can reduce linear growth retardation (stunting) in children aged 6-36 months over a 5-year period in a food-insecure population in Ethiopia. DESIGN: We used data collected through an operations research project run by Save the Children UK: the Child Caring Practices (CCP) project. Eleven neighbouring villages were purposefully selected to receive one of four interventions: (i) health; (iii) nutrition education; (iii) water, sanitation and hygiene (WASH); or (iv) integrated comprising all interventions. A comparison group of three villages did not receive any interventions. Cross-sectional surveys were conducted at baseline (2004) and for impact evaluation (2009) using the same quantitative and qualitative tools. The primary outcome was stunted growth in children aged 6-36 months measured as height (or length)-for-age Z-scores (mean and prevalence). Secondary outcomes were knowledge of health seeking, infant and young child feeding and preventive practices. SETTING: Amhara, Ethiopia. SUBJECTS: Children aged 6-36 months. RESULTS: The WASH intervention group was the only group to show a significant increase in mean height-for-age Z-score (+0·33, P = 0·02), with a 12·1 % decrease in the prevalence of stunting, compared with the baseline group. This group also showed significant improvements in mothers' knowledge of causes of diarrhoea and hygiene practices. The other intervention groups saw non-significant impacts for childhood stunting but improvements in knowledge relating to specific intervention education messages given. CONCLUSIONS: The study suggests that an improvement in hygiene practices had a significant impact on stunting levels. However, there may be alternative explanations for this and further evidence is required.

BACKGROUND: Values-based recruitment is a mandatory process for nursing programmes within UK higher education, with the Nursing Midwifery Council expecting that experts-by-experience are engaged in these recruitment and selection processes. The wider involvement of experts-by-experience in healthcare education is gaining momentum internationally with calls for engagement in all aspects of design and delivery; however, the impact of such involvement in recruitment of nursing students has received little attention, particularly in mental health nursing. AIM: To understand the impact of expert-by-experience involvement in the values-based recruitment of mental health nursing students from the perspective of candidates, experts-by-experience, and academic staff. DESIGN AND METHODS: This qualitative approach was co-designed and implemented by a research team comprised of academics, experts-by-experience, and student mental health nurses. Focus groups and an on-line survey were used to collect data, with Burnard's thematic analysis providing a framework for data analysis. SETTING/PARTICIPANTS: This study took place at one UK university. Participants included nurse academics, experts-by-experience, and student nurses with experience of a values-based recruitment process. RESULTS: Thematic analysis identified four themes: starting out, collaboration, rich assessment, and stakeholder gains. Whilst not without its challenges, the involvement of experts-by-experience in the recruitment of mental health nursing students was identified as delivering a robust recruitment process, encompassing academic abilities alongside the personal qualities required to make a 'good nurse'. Personal benefits for experts-by-experience, candidates, and academics were also reported. CONCLUSION: This study provides insights into the impact of experts-by-experience in supporting values-based recruitment. The approach is identified as enhancing the selection process by drawing from academic and lived experience perspectives and highlights to potential candidates, at the outset of their career, the value of meaningful engagement. These findings support the Nursing Midwifery Council's position that experts-by-experience should be engaged in the recruitment and selection of student nurses.

γ-Butyrolactone (GBL) is a popular drug of abuse which is easily available over the internet. Following a UK classification change to a class C drug in January 2010, internet supply has become difficult. Some of the effects have resulted in sourcing GBL from industrial solvents. We report a case of a 24-year-old man who was admitted for detoxification from GBL. He reported having sourced the GBL by diluting the contents of nail varnish remover pads with water. During his admission he developed a severe withdrawal delirium and acute renal failure. He required admission to the intensive care unit. Physicians and psychiatrists should be aware of toxic sources of GBL leading to renal failure and consider GBL in those presenting with agitation, psychosis or coma.

AIM: To explore the variation in mental health nursing students' understanding of recovery. BACKGROUND: In mental health practice clinical understanding of recovery has been challenged with a new understanding based on the individualised experiences of the person, often referred to as personal recovery. Despite international policy endorsement, practice has been slow to embrace the principles of personal recovery and little is known about student nurses' understanding of the concept. DESIGN: Qualitative phenomenographic study METHOD: In-depth semi-structured interviews including discussion of a clinical scenario, were conducted with 13 pre-registration student nurses. Data was analysed iteratively using a seven stage phenomenographic framework, identifying categories of description and the outcome space. RESULTS: Analysis revealed a branched outcome space with four qualitatively distinct ways of understanding recovery. Branch one can be broadly aligned to clinical recovery and contains one category only, 'Recovery as Clinical Improvement'. It is distinctly different from branch two which contains three categories on a continuum, which represent more and less complete ways of understanding personal recovery: 'Recovery as Making Progress', 'Recovery as Managing to Live Well' and 'Recovery as Learning to Live Differently'. Most participants demonstrated understanding in the less sophisticated categories. CONCLUSION: Recovery is central to mental health nursing, yet this study suggests it is a problematic concept for students. Features of personal recovery can be found in the second branch of the outcome space, with the most sophisticated category 'Learning to Live Differently' best representing the principles of recovery espoused in nursing literature and international policy. Phenomenography has allowed a more complex picture to emerge, replacing the dichotomy between clinical and personal recovery and enabling a differentiation between more and less complete ways of understanding personal recovery. This study addresses the lack of attention given to student nurse experiences of recovery. The insights support educators, both in clinical and academic settings, to address personal recovery in more explicit way where partial understanding can be explored.

PURPOSE OF REVIEW: This paper aimed to summarise existing literature on strategies to improve the healthiness of retail food environments in the East Asia and Pacific (EAP) region, and propose a prioritised research agenda on this topic. RECENT FINDINGS: Little research on retail food environments has been conducted in the EAP region. Several approaches for measuring retail food environments were identified, although none have been tailored to the EAP context. A small number of policies and initiatives to promote healthy retail food environments have been implemented in EAP. Lessons learnt from successful implementation of initiatives in other regions could be applied in EAP. Retail food environments have a strong influence on food choices and health outcomes. Research can contribute to efforts to improve the healthiness of retail food environments in EAP by (1) describing the current state of retail food environments to highlight areas of good practice and concern and (2) identifying policies and initiatives that are likely to be effective, and mechanisms for their successful implementation.

Survival and maturation of dorsal root ganglia sensory neurons during development depend on target-derived neurotrophins. These target-derived signals must be transmitted across long distances to alter gene expression. Here, we address the possibility that long-range retrograde signals initiated by target-derived neurotrophins activate a specialized transcriptional program. The transcription factor MEF2D is expressed in sensory neurons; we show that expression of this factor is induced in response to target-derived neurotrophins that stimulate the distal axons. We demonstrate that MEF2D regulates expression of an anti-apoptotic bcl-2 family member, bcl-w. Expression of mef2d and bcl-w is stimulated in response to activation of a Trk-dependent ERK5/MEF2 pathway, and our data indicate that this pathway promotes sensory neuron survival. We find that mef2d and bcl-w are members of a larger set of retrograde response genes, which are preferentially induced by neurotrophin stimulation of distal axons. Thus, activation of an ERK5/MEF2D transcriptional program establishes and maintains the cellular constituents of functional sensory circuits.

The Healthy Food Environment Policy Index (Food-EPI) aims to assess the extent of implementation of recommended food environment policies by governments compared with international best practices and prioritize actions to fill implementation gaps. The Food-EPI was applied in 11 countries across six regions (2015-2018). National public health nutrition panels (n = 11-101 experts) rated the extent of implementation of 47 policy and infrastructure support good practice indicators by their government(s) against best practices, using an evidence document verified by government officials. Experts identified and prioritized actions to address implementation gaps. The proportion of indicators at "very low if any," "low," "medium," and "high" implementation, overall Food-EPI scores, and priority action areas were compared across countries. Inter-rater reliability was good (GwetAC2 = 0.6-0.8). Chile had the highest proportion of policies (13%) rated at "high" implementation, while Guatemala had the highest proportion of policies (83%) rated at "very low if any" implementation. The overall Food-EPI score was "medium" for Australia, England, Chile, and Singapore, while "very low if any" for Guatemala. Policy areas most frequently prioritized included taxes on unhealthy foods, restricting unhealthy food promotion and front-of-pack labelling. The Food-EPI was found to be a robust tool and process to benchmark governments' progress to create healthy food environments.
