Understanding the Needs of People with Dementia and Family Carers

This is the first in a short series that presents case study examples of the positive work achieved by trusts who participated in the Royal College of Nursing's development programme to improve dementia care in acute hospitals. When a person with dementia is in hospital, poor understanding of individual needs and preferences can contribute to a lack of person-centred care. Similarly, the needs of family carers can often be overlooked and staff do not always appreciate these needs at such a stressful time. This article illustrates how three NHS trusts have addressed these issues. To help staff get to know patients with dementia, Salford Royal NHS Foundation Trust has implemented a patient passport. Similarly, The Shrewsbury and Telford Hospital NHS Trust has implemented a carer passport that overcomes the restrictions imposed by hospital visiting hours. Royal Devon and Exeter NHS Foundation Trust also focused on carers, holding a workshop to elicit feedback on what was important to them. This was a useful means of engaging with carers and helped staff to realise that even simple changes can have a significant effect.

Improving Activity and Engagement for Patients with Dementia

This is the second in a short series that presents case study examples of the positive work achieved by trusts that participated in the Royal College of Nursing’s development programme to improve dementia care in acute hospitals. Staff often think that there is insufficient time to get to know patients and carers, especially with large and challenging workloads. Combined with a lack of activities and stimulation for patients with dementia in hospital, this can result in poor engagement and a disconnect between staff and patients. To improve these relationships and give staff more time with patients, Cambridge University Hospitals NHS Foundation Trust has introduced bay nursing for patients with dementia, where one nurse is responsible for monitoring a bay alongside a healthcare assistant for an entire shift. Part of Betsi Cadwaladr University Health Board, Glan Clwyd Hospital in North Wales has focused on improving stimulation by creating an activity room with a specially trained activity worker, providing a relaxed and friendly setting where patients with dementia can take part in a range of activities and have lunch together.

Detection of ZnS phases in CZTS thin-films by EXAFS

Copper zinc tin sulfide (CZTS) is a promising Earthabundant thin-film solar cell material; it has an appropriate band gap of ~1.45 eV and a high absorption coefficient. The most efficient CZTS cells tend to be slightly Zn-rich and Cu-poor. However, growing Zn-rich CZTS films can sometimes result in phase decomposition of CZTS into ZnS and Cu2SnS3, which is generally deleterious to solar cell performance. Cubic ZnS is difficult to detect by XRD, due to a similar diffraction pattern. We hypothesize that synchrotron-based extended X-ray absorption fine structure (EXAFS), which is sensitive to local chemical environment, may be able to determine the quantity of ZnS phase in CZTS films by detecting differences in the second-nearest neighbor shell of the Zn atoms. Films of varying stoichiometries, from Zn-rich to Cu-rich (Zn-poor) were examined using the EXAFS technique. Differences in the spectra as a function of Cu/Zn ratio are detected. Linear combination analysis suggests increasing ZnS signal as the CZTS films become more Zn-rich. We demonstrate that the sensitive technique of EXAFS could be used to quantify the amount of ZnS present and provide a guide to crystal growth of highly phase pure films.

Estudo do galgamento em estruturas marítimas verticais utilizando o modelo numérico AMAZON

O galgamento oceânico é um fenómeno associado à interação de ondas com estruturas marítimas. Nesta dissertação estudou-se o galgamento em estruturas marítimas verticais através da aplicação do modelo numérico AMAZON, que é um modelo bidimensional, baseado na resolução das equações não lineares de águas pouco profundas. Para validar a sua aplicação a estruturas marítimas verticais impermeáveis, os resultados de caudal médio galgado obtidos com o modelo AMAZON foram comparados com os resultados de ensaios em modelo físico bidimensional realizados anteriormente e disponíveis na base de dados do projeto europeu CLASH. Os resultados foram ainda comparados com os das fórmulas empíricas e semi-empíricas de Van der Meer & Bruce de 2014, de Goda de 2008 e de Hedges & Reis de 2015. Antes da sua validação, o modelo foi calibrado utilizando um dos ensaios do CLASH. Para tal, realizou-se uma análise de sensibilidade a alguns parâmetros do modelo, concretamente da dimensão mínima da malha, da escala de aplicação do AMAZOM (à escala reduzida ou à do protótipo), da forma de modelação da parede vertical, já que, dado este modelo ser integrado na vertical, não é possível considerar paredes verticais sem utilizar um artifício de cálculo, dos valores de alguns dos parâmetros de entrada do modelo (profundidade mínima molhada e a profundidade mínima de fricção) e da dimensão do domínio de cálculo. Os resultados da calibração do AMAZON mostram que, por causa da precisão do modelo para os menores caudais médios de galgamento, se deve aplicar o modelo à escala do protótipo. Para estruturas verticais, a aproximação que o modelo faz, por defeito, para a secção vertical da estrutura através de um talude fictício a 10:1 apresenta melhores resultados que a utilização de um talude a 20:1. Contudo, ambos requerem a adoção de uma dimensão da malha bastante reduzida nesta zona e na sua vizinhança (0.03 m). No caso em estudo, os dois parâmetros de entrada do modelo não têm impacto significativo nos resultados, ao contrário do domínio de cálculo que, tal como recomendado na literatura de referência, se deve iniciar (fronteira de entrada) a aproximadamente um comprimento de onda do pé da estrutura. Os resultados obtidos mostram que, em geral, o AMAZON subestima o valor medido do caudal médio galgado com erros relativos variáveis entre -91% e -49%; apenas para um caso o modelo sobrestima o caudal médio, com um erro relativo de 43%. Quando comparado com as formulações empíricas e semi-empíricas, a fórmula de Van der Meer & Bruce apresenta melhores aproximações aos caudais médios medidos que constam na base de dados do CLASH, seguida da fórmula de Goda e dos resultados do modelo AMAZON, embora estes dois últimos apresentem valores bastante próximos. Assim, uma vez que o modelo está em constante desenvolvimento, espera-se que no futuro seja uma ferramenta mais poderosa. Contudo, enquanto não se fizerem melhorias no modelo e/ou não se estender a outros ensaios a análise feita no âmbito desta dissertação, os resultados sugerem que não há vantagem na sua utilização face às formulações empíricas e semi-empíricas disponíveis, tendo também em conta o significativo tempo computacional exigido para executar o AMAZON com a dimensão da malha escolhida.

Regulation of Nedd4-2 self-ubiquitination and stability by a PY motif located within its HECT-domain.

Ubiquitin ligases play a pivotal role in substrate recognition and ubiquitin transfer, yet little is known about the regulation of their catalytic activity. Nedd4 (neural-precursor-cell-expressed, developmentally down-regulated 4)-2 is an E3 ubiquitin ligase composed of a C2 domain, four WW domains (protein-protein interaction domains containing two conserved tryptophan residues) that bind PY motifs (L/PPXY) and a ubiquitin ligase HECT (homologous with E6-associated protein C-terminus) domain. In the present paper we show that the WW domains of Nedd4-2 bind (weakly) to a PY motif (LPXY) located within its own HECT domain and inhibit auto-ubiquitination. Pulse-chase experiments demonstrated that mutation of the HECT PY-motif decreases the stability of Nedd4-2, suggesting that it is involved in stabilization of this E3 ligase. Interestingly, the HECT PY-motif mutation does not affect ubiquitination or down-regulation of a known Nedd4-2 substrate, ENaC (epithelial sodium channel). ENaC ubiquitination, in turn, appears to promote Nedd4-2 self-ubiquitination. These results support a model in which the inter- or intra-molecular WW-domain-HECT PY-motif interaction stabilizes Nedd4-2 by preventing self-ubiquitination. Substrate binding disrupts this interaction, allowing self-ubiquitination of Nedd4-2 and subsequent degradation, resulting in down-regulation of Nedd4-2 once it has ubiquitinated its target. These findings also point to a novel mechanism employed by a ubiquitin ligase to regulate itself differentially compared with substrate ubiquitination and stability.

Functional multidisciplinary rehabilitation versus outpatient physiotherapy for non specific low back pain: randomized controlled trial.

INTRODUCTION: In recent decades the treatment of non-specific low back pain has turned to active modalities, some of which were based on cognitive-behavioural principles. Non-randomised studies clearly favour functional multidisciplinary rehabilitation over outpatient physiotherapy. However, systematic reviews and meta-analysis provide contradictory evidence regarding the effects on return to work and functional status. The aim of the present randomised study was to compare long-term functional and work status after 3-week functional multidisciplinary rehabilitation or 18 supervised outpatient physiotherapy sessions. METHODS: 109 patients with non-specific low back pain were randomised to either a 3-week functional multidisciplinary rehabilitation programme, including physical and ergonomic training, psychological pain management, back school and information, or 18 sessions of active outpatient physiotherapy over 9 weeks. Primary outcomes were functional disability (Oswestry) and work status. Secondary outcomes were lifting capacity (Spinal Function Sort and PILE test), lumbar range-of-motion (modified-modified Schöber and fingertip-to-floor tests), trunk muscle endurance (Shirado and Biering-Sörensen tests) and aerobic capacity (modified Bruce test). RESULTS: Oswestry disability index was improved to a significantly greater extent after functional multidisciplinary rehabilitation compared to outpatient physiotherapy at follow-up of 9 weeks (P = 0.012), 9 months (P = 0.023) and 12 months (P = 0.011). Work status was significantly improved after functional multidisciplinary rehabilitation only (P = 0.012), resulting in a significant difference compared to outpatient physiotherapy at 12 months' follow-up (P = 0.012). Secondary outcome results were more contrasted. CONCLUSIONS: Functional multidisciplinary rehabilitation was better than outpatient physiotherapy in improving functional and work status. From an economic point of view, these results should be backed up by a cost-effectiveness study.

Inflammatory markers and incident heart failure risk in older adults: the Health ABC (Health, Aging, and Body Composition) study.

OBJECTIVES: The purpose of this study was to evaluate the association between inflammation and heart failure (HF) risk in older adults. BACKGROUND: Inflammation is associated with HF risk factors and also directly affects myocardial function. METHODS: The association of baseline serum concentrations of interleukin (IL)-6, tumor necrosis factor-alpha, and C-reactive protein (CRP) with incident HF was assessed with Cox models among 2,610 older persons without prevalent HF enrolled in the Health ABC (Health, Aging, and Body Composition) study (age 73.6 +/- 2.9 years; 48.3% men; 59.6% white). RESULTS: During follow-up (median 9.4 years), HF developed in 311 (11.9%) participants. In models controlling for clinical characteristics, ankle-arm index, and incident coronary heart disease, doubling of IL-6, tumor necrosis factor-alpha, and CRP concentrations was associated with 29% (95% confidence interval: 13% to 47%; p < 0.001), 46% (95% confidence interval: 17% to 84%; p = 0.001), and 9% (95% confidence interval: -1% to 24%; p = 0.087) increase in HF risk, respectively. In models including all 3 markers, IL-6, and tumor necrosis factor-alpha, but not CRP, remained significant. These associations were similar across sex and race and persisted in models accounting for death as a competing event. Post-HF ejection fraction was available in 239 (76.8%) cases; inflammatory markers had stronger association with HF with preserved ejection fraction. Repeat IL-6 and CRP determinations at 1-year follow-up did not provide incremental information. Addition of IL-6 to the clinical Health ABC HF model improved model discrimination (C index from 0.717 to 0.734; p = 0.001) and fit (decreased Bayes information criterion by 17.8; p < 0.001). CONCLUSIONS: Inflammatory markers are associated with HF risk among older adults and may improve HF risk stratification.

Common variants near MC4R are associated with fat mass, weight and risk of obesity.

To identify common variants influencing body mass index (BMI), we analyzed genome-wide association data from 16,876 individuals of European descent. After previously reported variants in FTO, the strongest association signal (rs17782313, P = 2.9 x 10(-6)) mapped 188 kb downstream of MC4R (melanocortin-4 receptor), mutations of which are the leading cause of monogenic severe childhood-onset obesity. We confirmed the BMI association in 60,352 adults (per-allele effect = 0.05 Z-score units; P = 2.8 x 10(-15)) and 5,988 children aged 7-11 (0.13 Z-score units; P = 1.5 x 10(-8)). In case-control analyses (n = 10,583), the odds for severe childhood obesity reached 1.30 (P = 8.0 x 10(-11)). Furthermore, we observed overtransmission of the risk allele to obese offspring in 660 families (P (pedigree disequilibrium test average; PDT-avg) = 2.4 x 10(-4)). The SNP location and patterns of phenotypic associations are consistent with effects mediated through altered MC4R function. Our findings establish that common variants near MC4R influence fat mass, weight and obesity risk at the population level and reinforce the need for large-scale data integration to identify variants influencing continuous biomedical traits.
