A 39-year old right-handed agricultural service engineer developed rapidly evolving severe relapsing-remitting Multiple Sclerosis (MS). MR imaging showed multiple T2 hyperintensities throughout his neuro-axis (Figure 1A). Several lesions showed restricted diffusion, and two enhanced. He received steroids for each relapse, making a full recovery (EDSS 0).Wellcome Trus

Metabolism within the tumor microenvironment and its implication on cancer progression: an ongoing therapeutic target

Since reprogramming energy metabolism is considered a new hallmark of cancer, tumor metabolism is again in the spotlight of cancer research. Many studies have been carried out and many possible therapies have been developed in the last years. However, tumor cells are not alone. A series of extracellular components and stromal cells, such as endothelial cells, cancer-associated fibroblasts, tumor-associated macrophages and tumor-infiltrating T cells, surround tumor cells in the so-called tumor microenvironment. Metabolic features of these cells are being studied in deep in order to find relationships between metabolism within the tumor microenvironment and tumor progression. Moreover, it cannot be forgotten that tumor growth is able to modulate host metabolism and homeostasis, so that tumor microenvironment is not the whole story. Importantly, the metabolic switch in cancer is just a consequence of the flexibility and adaptability of metabolism and should not be surprising. Treatments of cancer patients with combined therapies including anti-tumor agents with those targeting stromal cell metabolism, anti-angiogenic drugs and/or immunotherapy are being developed as promising therapeutics.Mª Carmen Ocaña is recipient of a predoctoral FPU grant from the Spanish Ministry of Education, Culture and Sport.

Efficient derivation of NPCs, spinal motor neurons and midbrain dopaminergic neurons from hESCs at 3% oxygen

This protocol has been designed to generate neural precursor cells (NPCs) from human embryonic stem cells (hESCs) using a physiological oxygen (O(2)) level of 3% and chemically defined conditions. The first stage involves suspension culture of hESC colonies at 3% O(2), where they acquire a neuroepithelial identity over two weeks. This timescale is comparable to that at 20% O(2), but survival is enhanced. Sequential application of retinoic acid (RA) and purmorphamine (PM), from day 14 to 28, directs differentiation towards spinal motor neurons. Alternatively, addition of FGF-8 and PM generates midbrain dopaminergic neurons. OLIG2 induction in motor neuron precursors is 2-fold greater than at 20% O(2), whereas EN1 is 5-fold enhanced. 3% NPCs can be differentiated into all three neural lineages, and such cultures can be maintained long-term in the absence of neurotrophins. The ability to generate defined cell types at 3% O(2) should represent a significant advance for in vitro disease modelling and potentially cell-based therapies

Fish oil supplements, longevity and aging

Fish oil supplementation is of great medical and public interest with epidemiological evidence of health benefits in humans, in particular by conferring protection against heart diseases. Its anti-inflammatory properties have also been reported. Initial results from short-lived mouse strains showed that fish oil can increase lifespan, affecting pathways like inflammation and oxidation thought to be involved in the regulation of aging. Could fish oil and its omega-3 fatty acids act as geroprotectors? Probably not. A new study by Strong et al. challenges the role for fish oil supplementation in aging. Using a large cohort of genetically heterogeneous mice in three sites, part of the Interventions Testing Program of the NIA, Strong et al. show that fish oil supplementation at either low or high dosages has no effect on the lifespan of male or female mice. Although it is still possible that fish oil supplementation has health benefits for specific age-related diseases, it does not appear to slow aging or have longevity benefits

Caring for Infants in Out-of-Home Care in New South Wales: Carers' Perspectives

This report presents the findings of an online survey and individual interviews which explored the experiences of carers providing out-of-home care to infants in New South Wales. While there is increasing research related to the care of children and young people requiring OOHC, there is comparatively less specifically related to the care of infants. Survey data was collected from 142 carers in NSW providing OOHC to infants, and 13 individual interviews were conducted to gain insight to their experiences

Current provision of myelopathy education in medical schools in the UK: protocol for a national medical student survey

Introduction: Degenerative cervical myelopathy (DCM) is a common, disabling and progressive neurological condition triggered by chronic compression of the cervical spinal cord by surrounding degenerative changes. Early diagnosis and specialist management are essential to reduce disability, yet time to diagnosis is typically prolonged. Lack of sufficient representation of DCM in undergraduate and postgraduate medical curricula may contribute to the poor recognition of DCM by non-specialist doctors in clinical practice. In this study, our objective, therefore, is to assess DCM teaching provision in medical schools throughout the UK and to assess the impact of teaching on the DCM knowledge of UK medical students. Methods and analysis: A 19-item questionnaire capturing data on medical student demographics, myelopathy teaching and myelopathy knowledge was designed. Ethical approval was granted by the Psychology Research Ethics Committee, University of Cambridge. An online survey was hosted on Myelopathy.org, an international myelopathy charity. Students studying at a UK medical school are eligible for inclusion. The survey is advertised nationally through university social media pages, university email bulletins and the national student network of Myelopathy.org. Advertisements are scheduled monthly over a 12-month recruitment period. Participation is incentivised by entering consenting participants of completed surveys to an Amazon voucher prize draw. Responses are anonymised using participant-chosen unique identifier codes. A participant information sheet followed by an explicit survey question captures participant informed consent. Regular updates on the progress of the study will be published on Myelopathy.org. Ethics and Dissemination: Ethical approval for the study was granted by the Psychology Research Ethics Committee, University of Cambridge (PRE.2018.099). The findings of the study described in this protocol, and all other related work, will be submitted for publication in a peer-reviewed journal and will be presented at scientific conferences

Implementing the Namaste Care Program for residents with advanced dementia:exploring the perceptions of families and staff in UK care homes

Background: Increasing numbers of older people with advanced dementia are cared for in care homes. No cure is available, so research focused on improving quality of life and quality of care for people with dementia is needed to support them to live and die well. The Namaste Care programme is a multi-dimensional care program with sensory, psycho-social and spiritual components intended to enhance quality of life and quality of care for people with advanced dementia. The aim of the study was to establish whether the Namaste Care program can be implemented in UK care homes; and what effect Namaste Care has on the quality of life of residents with advanced dementia, their families and staff. This article explores the qualitative findings of the study, reporting the effect of the programme on the families of people with advanced dementia and care home staff, and presenting their perceptions of change in care. Methods: An organisational action research methodology was used. Focus groups and interviews were undertaken pre/post implementation of the Namaste Care program. The researcher kept a reflective diary recording data on the process of change. A comments book was available to staff and relatives in each care home. Data was analysed thematically within each care home and then across all care homes. Results: Six care homes were recruited in south London: one withdrew before the study was underway. Of the five remaining care homes, four achieved a full Namaste Care program. One care home did not achieve the full program during the study, and another discontinued Namaste Care when the study ended. Every home experienced management disruption during the study. Namaste Care challenged normal routinised care for older people with advanced dementia. The characteristics of care uncovered before Namaste was implemented were: chaos and confusion, rushing around, lack of trust, and rewarding care. After the programme was implemented these perceptions were transformed, and themes of calmness, reaching out to each other, seeing the person, and, enhanced well-being, emerged. Conclusions: Namaste Care can enrich the quality of life of older people with advanced dementia in care homes. The program was welcomed by care home staff and families, and was achieved with only modest expenditure and no change in staffing levels. The positive impact on residents quality of life influenced the well-being of family carers. Care staff found the changes in care enjoyable and rewarding. Namaste Care was valued for the benefits seen in residents; the improvement in relationships; and the shift towards a person-centred, relationship-based culture of care brought about by introducing the program. Namaste Care deserves further exploration and investigation including a randomised controlled trial
