Summary: There is accumulating evidence of BCMA and GPRC5D loss after treatment with T‐cell redirecting therapies in patients with relapsed/refractory multiple myeloma (RRMM). While complete CD38 loss is not observed upon relapses after treatment with anti‐CD38 monoclonal antibodies (mAb), there is downregulation of surface CD38 expression and decreased number and function of NK cells, which renders these patients resistant to retreatment with anti‐CD38 mAb. Here, we provide preclinical evidence that RRMM patients previously exposed to anti‐CD38 mAb could benefit from T‐cell‐based immunotherapy that depend less on CD38 antigen density and NK‐cell activity, such as the novel CD38/CD3xCD28 trispecific T‐cell engager, SAR442257.

DATA editing ,GENETIC disorders ,LIVER diseases ,CRISPRS ,NUCLEASES ,GENOME editing - Abstract
The deliberate and precise modification of the host genome using engineered nucleases represents a groundbreaking advancement in modern medicine. Several clinical trials employing these approaches to address metabolic liver disorders have been initiated, with recent remarkable outcomes observed in patients with transthyretin amyloidosis, highlighting the potential of these therapies. Recent technological improvements, particularly CRISPR Cas9‐based technology, have revolutionized gene editing, enabling in vivo modification of the cellular genome for therapeutic purposes. These modifications include gene supplementation, correction, or silencing, offering a wide range of therapeutic possibilities. Moving forward, we anticipate witnessing the unfolding therapeutic potential of these strategies in the coming years. The aim of our review is to summarize preclinical data on gene editing in animal models of inherited liver diseases and the clinical data obtained thus far, emphasizing both therapeutic efficacy and potential limitations of these medical interventions.

Summary: Chimeric antigen receptor (CAR) T‐cell therapies have increased the patients with relapsed/refractory multiple myeloma (RRMM) in whom standard electrophoretic techniques fail to detect the M‐protein. Quantitative immunoprecipitation mass spectrometry (QIP‐MS) can accurately measure serum M‐protein with high sensitivity, and identify interferences caused by therapeutic monoclonal antibodies. Here, we investigate the outcome of QIP‐MS in 33 patients treated with the academic BCMA‐directed CAR T‐cell ARI0002h (Cesnicabtagene Autoleucel). QIP‐MS offered more detailed insights than serum immunofixation (sIFE), identifying glycosylated M‐proteins and minor additional peaks. Moreover, the potential interferences owing to daratumumab or tocilizumab treatments were successfully detected. When analysing different assay platforms during patient's monitoring after ARI0002h administration, we observed that QIP‐MS showed a high global concordance (78.8%) with sIFE, whereas it was only moderate (55.6%) with bone marrow (BM)‐based next‐generation flow cytometry (NGF). Furthermore, QIP‐MS consistently demonstrated the lowest negativity rate across the different timepoints (27.3% vs. 60.0% in months 1 and 12, respectively). Patients with QIP‐MS(+)/BM‐based NGF(−) showed a non‐significant shorter median progression free survival than those with QIP‐MS(−)/BM‐based NGF(−). In summary, we show the first experience to our knowledge demonstrating that QIP‐MS could be particularly useful as a non‐invasive technique when evaluating response after CAR T‐cell treatment in MM.

- Abstract
The COVID-19 pandemic reminded us of the urgent need for new antivirals to control emerging infectious diseases and potential future pandemics. Immunotherapy has revolutionized oncology and could complement the use of antivirals, but its application to infectious diseases remains largely unexplored. Nucleoside analogs are a class of agents widely used as antiviral and anti-neoplastic drugs. Their antiviral activity is generally based on interference with viral nucleic acid replication or transcription. Based on our previous work and computer modeling, we hypothesize that antiviral adenosine analogs, like remdesivir, have previously unrecognized immunomodulatory properties which contribute to their therapeutic activity. In the case of remdesivir, we here show that these properties are due to its metabolite, GS-441524, acting as an Adenosine A2A Receptor antagonist. Our findings support a new rationale for the design of next-generation antiviral agents with dual - immunomodulatory and intrinsic - antiviral properties. These compounds could represent game-changing therapies to control emerging viral diseases and future pandemics. Synopsis: Adenosine analogs predicted to bind to the Adenosine A2A Receptor (A2AR) are endowed with immunomodulatory properties. These properties contribute to their antiviral function and are distinct from the intrinsic antiviral activity of these compounds. Computational modeling and molecular docking shows that remdesivir metabolite GS-441524 is predicted to bind to A2AR. Remdesivir and GS-441524 antagonize A2AR activation and downstream immunological effects in vitro and in vivo. A non-antiviral A2AR antagonist promotes T-cell infiltration and viral clearance in mice infected with SARS-CoV-2. Remdesivir has immunomodulatory effects analogous to an A2AR antagonist in promoting antiviral immune responses. Adenosine analogs predicted to bind to the Adenosine A2A Receptor (A2AR) are endowed with immunomodulatory properties. These properties contribute to their antiviral function and are distinct from the intrinsic antiviral activity of these compounds. [ABSTRACT FROM AUTHOR]

Questions: Marine rocky outcrops are model systems of community assembly under harsh conditions. The prevailing environmental conditions that determine a coast–inland gradient of stress and disturbance impose a strong environmental filter on community assembly. However, the Atlantic rocky outcrops of Uruguay challenge this assumption as they exhibit high plant diversity at small spatial scales. We investigated this study system to answer: (1) which environmental factors determine diversity at the local scale; (2) and how does the regional pool influence species composition along the coast–inland gradient? Methods: We analyzed the local and regional determinants of plant community assembly in four rocky sites along the Uruguayan coast. Through a random sampling approach stratified by distance to the coast, we recorded species occurrences and microenvironmental conditions. Observed taxa were assigned into different species assemblages according to their typical vegetation type. Generalized Linear Model (GLM)–Poisson regression, quantile regressions and hierarchical cluster analyses were used to identify the factors underlying local richness and the spatial vegetation structure. Results: Nine different vegetation types generate a mass effect that enhances local diversity. Unexpectedly, 56% of the species are from non‐marine environments — e.g. grasslands or hydrophilous herblands. Species assemblages were spatially clustered, with a turnover of these clusters along the coast–inland gradient. Elevation, distance to the coast and vegetation cover promoted richness, likely due to an attenuation of marine filters. Meanwhile, substrate availability reduced richness, likely due to competitive exclusion as a result of more resources and homogeneous microenvironmental conditions. Conclusions: The high local diversity along the marine rocky outcrops of Uruguay is best explained by a functionally diverse regional species pool, which interacts with local heterogeneity, and by conditions that enhance or attenuate the effect of marine stress. Effective conservation and management strategies are key to minimize the detrimental effects of urbanization, fragmentation, and non‐native plant invasions on these diverse habitats.

Astrocytes maintain CNS homeostasis but also critically contribute to neurological and psychiatric disorders. Such functional diversity implies an extensive signaling repertoire including extracellular vesicles (EVs) and nanotubes (NTs) that could be involved in protection or damage, as widely shown in various experimental paradigms. However, there is no information associating primary damage to the astrocyte genome, the DNA damage response (DDR), and the EV and NT repertoire. Furthermore, similar studies were not performed on hippocampal astrocytes despite their involvement in memory and learning processes, as well as in the development and maintenance of alcohol addiction. By exposing murine hippocampal astrocytes to 400 mM ethanol (EtOH) and/or 1 μM corticosterone (CTS) for 1 h, we tested whether the induced DNA damage and DDR could elicit significant changes in NTs and surface-attached EVs. Genetic damage and initial DDR were assessed by immunolabeling against the phosphorylated histone variant H2AX (γH2AX), DDR-dependent apoptosis by BAX immunoreactivity, and astrocyte activation by the glial acidic fibrillary protein (GFAP) and phalloidin staining. Surface-attached EVs and NTs were examined via scanning electron microscopy, and labeled proteins were analyzed via confocal microscopy. Relative to controls, astrocytes exposed to EtOH, CTS, or EtOH+CTS showed significant increases in nuclear γlH2AX foci, nuclear and cytoplasmic BAX signals, and EV frequency at the expense of the NT amount, mainly upon EtOH, without detectable signs of morphological reactivity. Furthermore, the largest and most complex EVs originated only in DNA-damaged astrocytes. Obtained results revealed that astrocytes exposed to acute EtOH and/or CTS preserved their typical morphology but presented severe DNA damage, triggered canonical DDR pathways, and early changes in the cell signaling mediated by EVs and NTs. Further deepening of this initial morphological and quantitative analysis is necessary to identify the mechanistic links between genetic damage, DDR, cell-cell communication, and their possible impact on hippocampal neural cells.

Background: Most health systems are insufficiently prepared to promote the participation of chronically ill patients in their care. Strong primary health care (PHC) strengthens patients' resources and thus promotes their participation. The tasks of providing continuous care to people with chronic diseases and promoting self‐management are the responsibility of PHC nurses. Recent research assessing enablers of or barriers to nurses' efforts to support patients' participation has mostly not considered the special situation of patients with chronic diseases or focused on the PHC setting. Objective: To investigate enablers of and barriers to PHC nurses' efforts to promote the participation of chronically ill patients in their care. Methods: We interviewed 34 practicing PHC nurses and 23 key informants with advanced knowledge of PHC nursing practice in Brazil, Germany and Spain. The data was analyzed using thematic coding. Results: We identified four categories of barriers and enablers. (1) Establishing bonds with patients: Interviewees emphasized that understanding patients' views and behaviours is important for PHC nurses. (2) Cooperation with relatives and families: Good relationships with families are fundamental, however conflicts within families could challenge PHC nurses efforts to strengthen participation. (3) Communication and cooperation within PHC teams: PHC nurses see Cooperative team structures as a potential enabler, while the dominance of a 'biomedical' approach to patient care is seen as a barrier. (4) Work environment: Interviewees agreed that increased workload is a barrier to patient participation. Discussion and Conclusions: Supporting patient participation should be acknowledged as an important responsibility for nurses by general practitioners and PHC planners. PHC nurses should be trained in communicative competence when discussing participation with chronically ill patients. Interprofessional education could strengthen other professionals' understanding of patient participation as a nursing task. Patient or Public Contribution: This study is part of a research project associated with the research network 'forges: User‐oriented care: Promotion of health in the context of chronic diseases and care dependency'. The study's focus and provisional results were discussed continuously with partners in health and social care practice and presented to and discussed with the public at two conferences in which patient representatives, professionals and researchers participated.

The aim of this study was to measure the vibration levels in one of the types of truck most used in Spain for the shipment of packaged goods, formed by tractor unit and air‐suspension semi‐trailer with 26 tonnes (26 000 kg) payload capacity, considering the most representative routes of the main Spanish road network. The data presented in this study will enable the development of new specific vibration tests and will help product and package engineers to reduce damage in transit. In this study, 30 transport routes recording nearly 10 000 km of the Spanish main road network have been selected and analysed, and power spectral density (PSD) profiles are provided to simulate truck transport in Spain using random vibration test methods. The resulting PSD profiles were established by generating two grms levels (0.21 and 0.15) obtaining the highest intensity from the calculation of the upper one‐sided normal tolerance limit (NTL) (30,95,50) and an average intensity profile at −6 dB with respect to the calculated NTL curve, which represents 70% of the lowest grms values of the study. This study uses NTL analysis to explore the vibration characteristics of a typical heavy goods transport vehicle type for various routes along main highways in Spain and propose new transport simulation test protocols dedicated to the Spanish main road distribution environment.

The advertisement of food and beverages on television and social media has been widely assessed, evidencing its powerful influence on children's dietary patterns and the development of childhood obesity. However, there is a gap in the evidence about advertisements near schools. The aim of this study was to describe and classify the nutritional quality and information of processed foods and alcoholic and non‐alcoholic beverages advertised near schools in three cities in the north of Spain. A descriptive analysis was performed from September to December 2021 in the cities of Oviedo, Gijón and Avilés in the Principality of Asturias (Spain). The nutritional quality and information of processed foods or beverages advertised within a 500 m radius of schools were assessed. The Nutri‐Score system was used for the classification of the nutritional quality of products and nutritional information, calories, fat, saturated fat, carbohydrates, sugars, protein and salt in 100 g or ml of each product was calculated. A total of 73.5% of the products were classified as "foods to eat less often and in small amounts," and 22.6% and 46.3% were classified as D or E, respectively, according to the Nutri‐Score system. Finally, 57.5%, 56.4% and 78.5% of the products showed a medium to high content of fat, saturated fat and sugar, respectively. In conclusion, the food and drink advertisements surrounding schools in the assessed cities promote many products of low nutritional value, rich in fat, saturated fat and sugars, which have high obesogenic potential.

As a result of policies to reduce public deficit, nonprofit organizations have been forced to turn to charitable donations in order to diversify their revenue structure and thus reduce their levels of financial distress. Public administrations have supported this process through tax mechanisms designed to provide a legal framework that will encourage private philanthropy. Our aim is to analyse the role of nonprofit tax regulations in moderating the influence of revenue diversification on insolvency risk. To this end, we drew a sample of 406 nonprofit organizations located in Aragon and Navarre, two European regions with different tax regulations, for the period 2008–2018. Our results reveal that some tax regime requirements, such as the organizational purpose, minimum initial endowment, engagement in commercial activity, and accountability and monitoring standards, have a positive impact on revenue diversification and the reduction of financial distress and vulnerability. However, we also detect differences between regions which suggest that tax harmonization for nonprofit organizations remains a challenge. [ABSTRACT FROM AUTHOR]

Background: The role of ERG‐status molecular subtyping in prognosis of prostate cancer (PCa) is still under debate. In this study, we identified differentially expressed genes (DEGs) according to ERG‐status to explore their enriched pathways and implications in prognosis in Hispanic/Latino PCa patients. Methods: RNA from 78 Hispanic PCa tissues from radical prostatectomies (RP) were used for RNA‐sequencing. ERGhigh/ERGlow tumor groups were determined based on the 1.5‐fold change median expression in non‐tumor samples. DEGs with a False Discovery Rate (FDR) < 0.01 and a fold change >2 were identified between ERGhigh and ERGlow tumors and submitted to enrichment analysis in MetaCore. Survival and association analyses were performed to evaluate biochemical recurrence (BCR)‐free survival. Results: The identification of 150 DEGs between ERGhigh and ERGlow tumors revealed clustering of most of the non‐BCR cases (60%) into de ERGhigh group and most of the BCR cases (60.8%) in ERGlow group. Kaplan–Meier survival curves showed a worst BCR‐free survival for ERGlow patients, and a significant reduced risk of BCR was observed for ERGhigh cases (OR = 0.29 (95%CI, 0.10–0.8)). Enrichment pathway analysis identified metabolic‐related pathways, such as the renin‐angiotensin system and angiotensin maturation system, the linoleic acid metabolism, and polyamines metabolism in these ERG groups. Conclusions: ERGlow tumor cases were associated with poor BCR‐free survival in our Hispanic/Latino patients, with metabolism‐related pathways altered in the BCR progression. Impact: Our findings suggest the need to dissect the role of diet, metabolism, and lifestyle as risk factors for more aggressive PCa subtypes. [ABSTRACT FROM AUTHOR]

Background: The most common chronic sequela after stroke is the loss of arm function, and functional electrical stimulation (FES) applied to the forearm muscles is one of the options to treat it. Surface multi‐field electrodes have emerged, showing a great potential to improve the selectivity of the stimulation, delay muscle fatigue, and provide easier donning and doffing. The muscular selectivity takes on special relevance in the rehabilitation of the upper extremity as hand dexterity requires a wide diversity of specific muscle actions. Methods: This pilot study analyses the movements generated in the wrist and fingers using a commercial multi‐field technology‐based FES device (Fesia Grasp). The study included five patients with hemiplegic subacute stroke, in which scanning of all cathodes of the electrode was carried out daily for 5 days, in two different forearm positions, with the resulting movements being labeled by experienced therapists. Results: The aim of this pilot study was to determine if there were differences between subjects and between forearm positions in terms of produced movements. Movements of the wrist (two movements) and the fingers (six movements) could be achieved in two different forearm positions. Conclusions: The multi‐field electrode of Fesia Grasp enables to generate a wide range of movements of the hand in different positions. This fact could allow to produce more physiological movement patterns during the rehabilitation process with FES, which could have a beneficial effect on the recovery of patients with neurological diseases.

Objective: This study aimed to determine whether race modifies the association between obesity and cancer death. Methods: The Pennington Center Longitudinal Study included 18,296 adults; 35.0% were male and 34.3% were Black. The primary end point was death from cancer. Results: During a follow-up of 14.3 years, 346 cancer deaths occurred. Among men, race modified the association of BMI and cancer death (p
interaction = 0.045); compared with a BMI of 22 kg/m², a BMI of 35 in White men was associated with a hazard ratio of 1.74 (95% CI: 1.38-2.21), and in Black men, the hazard ratio was 0.64 (95% CI: 0.45-0.90). Among women, race did not modify the association of BMI and cancer death (pinteraction =0.43); however, compared with a BMI of 22, a BMI of 35 in White women was associated with a hazard ratio of 1.42 (95% CI: 1.18-1.70) and in Black women, the hazard ratio was 0.99 (95% CI: 0.82-1.20). Conclusions: In this diverse cohort of adults, having obesity was associated with an increased risk of cancer death in White men and women. In contrast, having obesity was associated with a reduced risk of cancer death in Black men and did not influence risk in Black women. [ABSTRACT FROM AUTHOR]- Published

Sensing and response to high temperatures are crucial to prevent heat‐related damage and to preserve cellular and metabolic functions. The response to heat stress is a complex and coordinated process that involves several subcellular compartments and multi‐level regulatory networks that are synchronized to avoid cell damage while maintaining cellular homeostasis. In this review, we provide an insight into the most recent advances in elucidating the molecular mechanisms involved in heat stress sensing and response in Marchantia polymorpha. Based on the signaling pathways and genes that were identified in Marchantia, our analyses indicate that although with specific particularities, the core components of the heat stress response seem conserved in bryophytes and angiosperms. Liverworts not only constitute a powerful tool to study heat stress response and signaling pathways during plant evolution, but also provide key and simple mechanisms to cope with extreme temperatures. Given the increasing prevalence of high temperatures around the world as a result of global warming, this knowledge provides a new set of molecular tools with potential agronomical applications. Sensing and response to high temperatures are crucial mechanisms to prevent heat‐related damage and to preserve cellular functions. In this review we aim to provide an insight into the most recent advances in elucidating the mechanisms and pathways involved in the response to heat stress in the bryophyte Marchantia polymorpha. We discuss conserved and divergent pathways that relate temperature sensing with a plethora of transduction cascades that are emerging as central future research directions. [ABSTRACT FROM AUTHOR]

Diatoms are unicellular organisms containing red algal‐derived plastids that probably originated as result of serial endosymbioses between an ancestral heterotrophic organism and a red alga or cryptophyta algae from which has only the chloroplast left. Diatom mitochondria are thus believed to derive from the exosymbiont. Unlike animals and fungi, diatoms seem to contain ancestral respiratory chains. In support of this, genes encoding gamma type carbonic anhydrases (CAs) whose products were shown to be intrinsic complex I subunits in plants, Euglena and Acanthamoeba were found in diatoms, a representative of Stramenopiles. In this work, we experimentally show that mitochondrial complex I in diatoms is a large complex containing gamma type CA subunits, supporting an ancestral origin. By using a bioinformatic approach, a complex I integrated CA domain with heterotrimeric subunit composition is proposed. [ABSTRACT FROM AUTHOR]

Summary: Microbial communities in hypersaline underground waters derive from ancient organisms trapped within the evaporitic salt crystals and are part of the poorly known subterranean biosphere. Here, we characterized the viral and prokaryotic assemblages present in the hypersaline springs that dissolve Triassic‐Keuper evaporite rocks and feed the Añana Salt Valley (Araba/Alava, Basque Country, Spain). Four underground water samples (around 23% total salinity) with different levels of exposure to the open air were analysed by means of microscopy and metagenomics. Cells and viruses in the spring water had lower concentrations than what are normally found in hypersaline environments and seemed to be mostly inactive. Upon exposure to the open air, there was an increase in activity of both cells and viruses as well as a selection of phylotypes. The underground water was inhabited by a rich community harbouring a diverse set of genes coding for retinal binding proteins. A total of 35 viral contigs from 15 to 104 kb, representing partial or total viral genomes, were assembled and their evolutionary changes through the spring system were followed by SNP analysis and metagenomic island tracking. Overall, both the viral and the prokaryotic assemblages changed quickly upon exposure to the open air conditions. [ABSTRACT FROM AUTHOR]

Objective: Anthropometric measures of obesity, including BMI and waist circumference (WC), do not quantify excess adiposity and metabolic abnormalities consistently across racial populations. This study tested the hypothesis that participant race modifies the association of anthropometric measures of obesity and cancer risk.Methods: This prospective cohort (The Pennington Center Longitudinal Study) included 18,296 adults, 6,405 (35.0%) male sex and 6,273 (34.3%) Black race. The primary exposures were BMI (weight in kilograms/height in meters squared) and WC (centimeters). The primary end point was the time from study enrollment to diagnosis of histologically confirmed invasive cancer.Results: During a median follow-up of 14.0 years (interquartile range: 9.8-19.0 years), invasive cancer occurred in 1,350 participants. Among men, race modified the association of BMI (Pinteraction = 0.02) and WC (Pinteraction = 0.01) with cancer incidence; compared with a BMI of 22 kg/m2 , a BMI of 35 kg/m2 in White men was associated with a hazard ratio of 1.83 (95% CI: 1.58-2.12), whereas in Black men, the hazard ratio was 0.89 (95% CI: 0.72-1.11). Among women, race did not modify the association of BMI (Pinteraction = 0.41) or WC (Pinteraction = 0.36) with cancer incidence.Conclusions: In this diverse cohort of adults, participant race and sex modified the prognostic associations of anthropometric measures of obesity and cancer risk.

Background and purpose: Spain has been one of the countries more heavily stricken by SARS‐CoV‐2, which has had huge implications for stroke care. The aim was to analyse the impact of the COVID‐19 epidemic outbreak on reperfusion therapies for acute ischaemic stroke in the northwest of Spain. Methods: This was a Spanish multicentre retrospective observational study based on data from tertiary hospitals of the NORDICTUS network. All patients receiving reperfusion therapy for ischaemic stroke between 30 December 2019 and 3 May 2020 were recorded, and their baseline, clinical and radiological characteristics, extra‐ and intra‐hospital times of action, Code Stroke activation pathway, COVID‐19 status, reperfusion rate, and short‐term outcome before and after the setting of the emergency state were analysed. Results: A total of 796 patients received reperfusion therapies for ischaemic stroke. There was a decrease in the number of patients treated per week (46.5 patients per week vs. 39.0 patients per week, P = 0.043) and a delay in out‐of‐hospital (95.0 vs. 110.0 min, P = 0.001) and door‐to‐needle times (51.0 vs. 55.0, P = 0.038). Patients receiving endovascular therapy obtained less successful reperfusion rates (92.9% vs. 86.6%, P = 0.016). COVID‐19 patients had more in‐hospital mortality. Conclusion: A decrease in the number of patients benefiting from reperfusion therapies was found, with a delay in out‐of‐hospital and door‐to‐needle times and worse reperfusion rates in northwest Spain. COVID‐19 patients had more in‐hospital mortality. [ABSTRACT FROM AUTHOR]

Aim(s): This commentary aims to raise awareness of the possible causes of "missed nursing care" in health promotion and to propose possible solutions. Background: Although health promotion is an essential function of nursing practice, "missed nursing care" has been scarcely studied in this area. It is crucial to know both its causes and possible strategies to prevent it. Evaluation: We used evidence to identify possible causes of "missed nursing care" in health promotion, and we classified them into categories. We suggested the concept of capacity building to address its underlying causes. Key issue(s): Four main factors are involved in "missed nursing care" in health promotion, that is intrapersonal, interpersonal, organisational and cultural. Capacity building, including the development of knowledge, skills, commitment, structures, systems and leadership, could reduce missed care. Conclusion(s): "Missed nursing care" in health promotion is complex and is multifactorial in its origins. Capacity building could be a way to address its causes. Implications for Nursing Management: Nursing care in health promotion is paramount and a long‐term investment that can contribute to the sustainability of the health system. Organisations and managers could view capacity building processes as a tool to prevent "missed nursing care" in health promotion. [ABSTRACT FROM AUTHOR]

Purpose: Nurses are well‐positioned to play an active role in the development of innovation in health care. However, their contribution to health innovation is poorly recognized and often invisible. The aim of this study was to determine the profile of innovative ideas recorded by nurses in the Innòbics ideas bank, a corporate virtual community of open innovation. Design and Methods: We used a cross‐sectional study design. We identified all the innovative ideas recorded in Innòbics from June 8, 2016, to July 6, 2018. To be eligible, the ideas had to be recorded by nurses. Each innovative idea recorded was assessed by the Certification Evaluation Committee of Innòbics. After collective discussion during the evaluation sessions, each committee member independently scored the idea. The screening decision was based on the overall average score. The following variables were collected from each innovative idea that was recorded: (a) level of health care where the idea originated (primary care or secondary care), (b) subject or category according to the classification of the Agency for Healthcare Research and Quality Health Care Innovations Exchange, (c) ratings relative to each screening criteria, and (d) the result of the screening decision: stored = ideas that were poorly developed and in which it was not possible to identify their potential for innovation; susceptible of improvement = potential ideas that needed to be improved and whose authors received comments from the evaluation committee; validated = ideas that continued the process to become innovation projects; forwarded = ideas that were not innovative but they were a complaint or a proposal for quality improvement (these were forwarded to the institutional department concerned). Findings: A total of 246 innovative ideas were recorded in the period of the study, 61 (24.8%) of which were recorded by nurses. The subjects and categories of these ideas were diverse, highlighting aspects such as patient‐centered care, quality improvement strategies, preventive and chronic care, and primary care. Thirty‐five (57.4%) of these innovative ideas were stored, 13 (21.3%) were susceptible to improvement, 11 (18.0%) were forwarded, and 2 (3.3%) were validated. Conclusions: The results demonstrated that approximately a quarter of the ideas were recorded by nurses. Subjects and categories of these ideas were diverse, some of them closely related to the profession and nursing practice. Two ideas were identified as potential innovation projects. Innòbics can act as an organizational tool that promotes a climate for innovation in health care. Clinical Relevance: This study recognizes nurses' contribution to a healthcare innovation initiative and their interest in sharing innovative ideas. Its findings provide useful insights into a virtual community of open innovation such as an organizational tool for encouraging creativity and innovation in healthcare. Likewise, there is also a need for further development of nurses to master healthcare innovation as a basic competence. [ABSTRACT FROM AUTHOR]

Background and purpose: The aim was to identify whether post‐stroke hyperglycaemia (PSH) influences the levels of circulating biomarkers of brain damage and repair, and to explore whether these biomarkers mediate the effect of PSH on the ischaemic stroke (IS) outcome. Methods: This was a secondary analysis of the Glycaemia in Acute Stroke II study. Biomarkers of inflammation, prothrombotic activity, endothelial dysfunction, blood–brain barrier rupture, cell death and brain repair processes were analysed at 24–48 h (baseline) and 72–96 h (follow‐up) after IS. The associations of the biomarkers and stroke outcome (modified Rankin Scale score at 3 months) based on the presence of PSH were compared. Results: A total of 174 patients participated in this sub‐study. Brain‐derived neurotrophic factor (BDNF) at admission was negatively correlated with glucose levels. PSH was associated with a trend toward higher levels of endothelial progenitor cells (EPCs) at baseline. The EPCs in the PSH group then decreased in the follow‐up samples (−8.5 ± 10.3) compared with the non‐PSH group (4.7 ± 7.33; P = 0.024). However, neither BDNF nor EPC values had correlation with the 3‐month outcome. Higher interleukin‐6 at follow‐up was associated with poor outcomes (modified Rankin Scale > 2) independently of PSH. Conclusion: Post‐stroke hyperglycaemia appears to be associated with a negative regulation of BDNF and a different reaction in EPC levels. However, neither BDNF nor EPCs showed significant mediation of the PSH association with IS outcome, and only higher interleukin‐6 in the follow‐up samples (72–96 h) was related to poor outcomes, independently of PSH status. Further studies are needed to achieve definite conclusions. [ABSTRACT FROM AUTHOR]

Summary: Introduction: Significant health disparities exist in asthma and obesity for African American youths. Successful interventions present an opportunity to address these disparities but require detailed study in order to ensure generalizability. This study investigated the intersection of obesity, neighbourhood disadvantage, and asthma. Methods: Data were extracted from 129 African American females ages 13 to 19 years (mean = 15.6 years [SD = 1.9]). Obesity was measured via body mass index (BMI). Asthma status was based on clinical diagnosis and/or results of the International Study of Asthma and Allergies during Childhood (ISAAC) questionnaire. The concentrated disadvantage index (CDI) assessed neighbourhood disadvantage. Results: Findings showed that 21.5% (n = 28) of participants were clinically defined as having asthma, 76.2% (n = 99) had obesity, and 24.9% (n = 31) were classified without obesity. The mean BMI was 35.1 (SD = 9.1) and the mean CDI was 1.0 (SD = 0.9). CDI and obesity were significantly associated in participants without asthma, but not in those with asthma. Multivariable linear regression results showed a significant interaction between CDI and asthma (t value = 2.2, P =.03). Conclusion: In sum, results from this study found that asthma moderated the relationship between neighbourhood disadvantage and obesity. [ABSTRACT FROM AUTHOR]

Background and Aim: Chronic Helicobacter pylori infection causes gastric mucosal inflammation as an important antecedent of gastric cancer. We aimed to evaluate associations of blood markers of inflammation with gastric intestinal metaplasia and dysplasia in H. pylori‐infected individuals. Methods: We compared pre‐treatment serum levels of immune‐related and inflammation‐related markers between 99 individuals with intestinal metaplasia or dysplasia and 75 control individuals with non‐atrophic gastritis within an H. pylori eradication trial in Mexico. Serum levels of 28 markers measured with Luminex bead‐based assays were categorized in tertiles as low (T1), middle (T2), and high (T3). Logistic regression models were used to calculate age‐adjusted and sex‐adjusted odds ratios and 95% confidence intervals. All statistical tests were two‐sided, and significance values were adjusted for multiple comparisons using false discovery rate methods. Results: Five markers were nominally associated (Ptrend < 0.05) with the presence of advanced premalignant gastric lesions. Adjusted odds ratios (95% confidence interval) of T2 and T3 versus T1 were 4.09 (1.65–10.17) and 3.08 (1.23–7.68) for CCL3/MIP1A, 3.21 (1.33–7.75) and 2.69 (1.10–6.57) for CCL20/MIP3A levels, 1.79 (0.77–4.18) and 2.39 (1.02–5.60) for IL‐1β, 1.34 (0.56–3.19) and 3.02 (1.29–7.12) for IL‐4, and 1.07 (0.44–2.59) and 3.07 (1.32–7.14) for IL‐5, respectively. Two (IL‐4 and IL‐5) of the five markers had false discovery rate adjusted Ptrend < 0.2. Conclusions: Our results suggest that certain Th2 and other cytokines may have a role in promoting carcinogenesis in the setting of H. pylori infection. Additional research is needed to replicate these findings, extend to pre‐diagnostic samples, and elucidate the underlying mechanisms. [ABSTRACT FROM AUTHOR]

Purpose: Migration of nurses is not a new or recent event. During the past few decades, nursing migration flows have been a constant trend worldwide. The main objective of this study was to explore the motivations, beliefs, and expectations that Spanish nurses had when considering migration to another country in the near future. Design: Cross‐sectional, Internet survey of Spanish nurses planning migration for professional reasons. Methods: Ad hoc, web‐based questionnaire following the Nurses Early Exit Study guidelines. Findings: One hundred seventy‐two nurses responded. Fifty percent of the participants intended to emigrate in the following 6 months and had chosen the United Kingdom as their destination. The most important drivers of migration were unemployment or precarious employment, and professional development. Fifty‐eight percent of the participants were very afraid of experiencing discrimination or rejection. Conclusions: This first study conducted in Spain directly exploring determinants of nurse migration highlighted globalization‐driven factors and specific acculturation fears. Clinical Relevance: Employment uncertainty and professional development remain key push drivers for migration of Spanish nurses. Discrimination and rejection due to migrancy were concerns for 60% of the participants. [ABSTRACT FROM AUTHOR]

Aim To determine mortality and mobility rates after hip fracture. Methods A prospective study ( n = 199 patients) was carried out in the Health Care Center of A Coruña ( Spain) during the period between January 2009 and December 2011. A descriptive study, and Cox and logistic regression analysis were carried out. Informed consent and ethical review board approval were obtained (code 2010/120 CEIC Galicia). Results The patients' mean age was 82.5 ± 8.4 years and 76% were female. The average Charlson Comorbidity Index score was 6.1 ± 2.1. Creatinine clearance <60 mL/min/1.73 m2 was 44%. The probability of survival 6 months after hip fracture was 89.2% and the survival rate at 12 months was 81.4%. Cox regression analysis showed that the indicator that most influenced mortality rate was comorbidity ( HR = 1.133; P = 0.020) and age approaching borderline statistical significance ( HR = 1.034; P = 0.064). The Parker Mobility Score decreased significantly ( P < 0.001) after hip fracture. Before fracture, 19% of the patients were able to get about the house, 26% were able to get out of the house and 55% were able to go shopping. After hip fracture (90 days), the percentages changed to 56.2%, 19.1% and 24.7%, respectively ( P < 0.001). After taking into account age, sex, type of fracture, surgical delay, previous fracture and comorbidity, the only indicator capable of predicting incapacity to walk was comorbidity. Conclusions Comorbidity is the best predictor of mortality and mobility after hip fracture. Geriatr Gerontol Int 2016; 16: 561-569. [ABSTRACT FROM AUTHOR]

Background and purpose: The aim of this study was to describe the clinical and epidemiological characteristics of acute ischaemic stroke (AIS) in patients with atrial fibrillation (AF) previously treated with oral anticoagulants (OACs) according to the type of OAC prescribed. Also, to analyze the outcomes of the patients and the therapeutic approach adopted by the neurologist in the acute phase and for secondary prevention. Methods: We performed a multicenter, observational study based on prospective registries. We included patients with AF treated with OACs admitted for AIS over a 1‐year period. Detailed clinical data and functional outcome at 3 months (modified Rankin Scale score) were collected. Patients were divided into two groups according to their pre‐AIS anticoagulant therapy: vitamin K antagonists (AIS‐VKA) and direct‐acting OACs (AIS‐DOAC). Results: We recruited 1240 patients (80.4% AIS‐VKA and 19.6% AIS‐DOAC). In the AIS‐DOAC group, transient ischaemic attack was more frequent (18.1% vs. 10.8%; P = 0.001), symptomatic hemorrhagic transformation was less frequent (1.6% vs. 4.6%; P = 0.035) and hospital stay was shorter (median 6 vs. 7 days; P = 0.03). Intravenous thrombolysis was more commonly used in AIS‐VKA (9.2% vs. 1.6%; P < 0.001). There were no differences between the groups with respect to mechanical thrombectomy, mortality and modified Rankin Scale score at 3 months. At 3 months, 54% of patients required a DOAC as antithrombotic treatment for secondary prevention. Conclusions: Patients with AF treated with DOACs who experienced AIS more frequently had transient symptoms (transient ischaemic attack), less symptomatic hemorrhagic transformation and a shorter mean stay than those treated with VKAs. Most patients who had been previously anticoagulated with AIS received long‐term treatment with DOACs. [ABSTRACT FROM AUTHOR]

- Abstract
Summary: Objective: This study was conducted to determine the role of obesity and race in intracerebral haemorrhage (ICH) outcomes. Methods: The Get with the guideline‐Stroke database was queried for all admitted patients with spontaneous ICH. Secondary causes of ICH were excluded. Body mass index (BMI) was classified using the Center for Disease Control guidelines. Race was classified as White or non‐White. Demographics, clinical, imaging data were retrieved. Outcome measures were hematoma expansion at 24 h and discharge disposition. Results: A total of 428 patients were included in our analysis. Female gender, past history of congestive heart failure, diabetes mellitus, HbA1c, blood pressure, ICH volume, ICH location, intraventricular haemorrhage and hospital length of stay deferred across BMI categories. On multivariate analysis, along with obese categories, age, ICH location and ICH volume were independent predictors of poor outcomes (hematoma expansion and poor discharge disposition). After adjusting for these variables, obesity remained a predictor of poor disposition outcome compared with normal and overweight subjects; Normal vs. Obese OR 0.26 CI 0.115–0.593 p = 0.0014; Obese vs. Overweight OR 3.79 CI 1.68–8.52 p = 0.0013. Nonetheless, obesity did not influence hematoma expansion. Overall, BMI‐race classification did not influence outcomes. However, among non‐Whites, the obese category had higher odds of a poor disposition outcome than normal (OR 6.84 CI 2.12–22.22 p = 0.0013) or overweight (OR 8.45 CI 2.6–27.49 p = 0.0004) categories. Conclusion: An obesity paradox in ICH was not observed in our cohort. In the non‐White population, patients with obesity were likely to be associated with poor disposition outcome. Similar findings were not observed in White population. [ABSTRACT FROM AUTHOR]

In this cross-sectional study, we explored course content related to pharmacology and/or healthcare products and supplies in all nursing degree programs in Spain. Changes in nurse-prescribing legislation in Spain require that nurses take a certification course before prescribing over-the-counter products and medications. Using a cross-sectional descriptive study, between July and September 2014, the degree programs of all centers that offer a degree in nursing in Spain were examined, selecting those with course information available online. All centers offered at least one pharmacology course. One-third of the required courses had content related to pharmacology and healthcare products/supplies. The analysis showed that the course content and training received during the current nursing degree program provides the knowledge and skills needed to prescribe healthcare products/supplies and medications that do not now require a doctor's prescription, without the need for additional training and certification. It is essential that government regulation of nursing education be aligned with nursing competencies, curriculum standards, clinical practice, and evidence-based research to provide the maximum level of confidence for nursing professionals and their patients.

Background and purpose The aim of the study was to analyze the effect of conventional glucose management, which aimed to maintain glucose levels <155 mg/dL (8.5 mmol/L), on glucose control and the outcomes of patients with acute ischaemic stroke ( IS) in a clinical practice setting. Methods This was a multicenter, prospective cohort study of patients with acute IS. Patients were classified into four groups based on their initial 48-h capillary glucose levels and the administration of and response to corrective treatment: (i) untreated and maximum glucose levels <155 mg/dL (8.5 mmol/L) within the first 48 h; (ii) treated and good responders [glucose levels persistently <155 mg/dL (8.5 mmol/L)]; (iii) treated and non-responders [any glucose values ≥155 mg/dL (8.5 mmol/L) during the 24 h after the start of corrective treatment]; and (iv) untreated with any glucose value ≥155 mg/dL (8.5 mmol/L). The primary outcome was death or dependence at 3 months (blinded rater). Results A total of 213 patients were included. Ninety-seven (45.5%) patients developed glucose levels ≥155 mg/dL (8.5 mmol/L), 69 (71.1%) underwent corrective treatment and 31 patients underwent no corrective treatment at the physician's discretion [28 of whom had isolated values ≥155 mg/dL (8.5 mmol/L)]. Only 11 (16%) patients responded to conventional treatment, whereas 58 (84%) patients were non-responsive. Non-responders showed a twofold higher risk of death or dependence at 3 months (odds ratio, 2.472; 95% confidence interval, 1.096-5.576; P = 0.029). Conclusions Lack of response to conventional treatment for glucose management in acute IS is frequent and associated with poor outcomes. [ABSTRACT FROM AUTHOR]

Background Racial variation in the relationship between blood glucose and hemoglobin A1c ( HbA1c) complicates diabetes diagnosis and management in racially mixed populations. Understanding why HbA1c is persistently higher in blacks than whites could help reduce racial disparity in diabetes outcomes. Objective Test the hypothesis that neighborhood disadvantage is associated with inflammation and poor metabolic control in a racially mixed population of pediatric type 1 diabetes patients. Methods Patients (n = 86, 53 white, 33 black) were recruited from diabetes clinics. Self-monitored mean blood glucose ( MBG) was downloaded from patient glucose meters. Blood was collected for analysis of HbA1c and C-reactive protein ( CRP). Patient addresses and census data were used to calculate a concentrated disadvantage index ( CDI). High CDI reflects characteristics of disadvantaged neighborhoods. Results HbA1c and MBG were higher (p < 0.0001) in blacks [10.4% (90.3 mmol/mol), 255 mg/dL] than whites [8.9% (73.9 mmol/mol), 198 mg/dL). CDI was higher in blacks (p < 0.0001) and positively correlated with HbA1c (r = 0.40, p = 0.0002) and MBG (r = 0.35, p = 0.0011) unless controlled for race. CDI was positively associated with CRP by linear regression within racial groups. CRP was not different between racial groups, and was not correlated with MBG, but was positively correlated with HbA1c when controlled for race (p = 0.04). Conclusions Neighborhood disadvantage was associated with inflammation and poor metabolic control in pediatric type 1 diabetes patients. Marked racial differences in potential confounding factors precluded differentiation between genetic and environmental effects. Future studies should recruit patients matched for neighborhood characteristics and treatment regimen to more comprehensively assess racial variation in HbA1c. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this work is to search for new metrics that could give more reliable acceptance/ rejection criteria on the IMRT verification process and to offer solutions to the discrepancies found among different conventional metrics. Therefore, besides conventional metrics, new ones are proposed and evaluated with new tools to find correlations among them. These new metrics are based on the processing of the dose-volume histogram information, evaluating the absorbed dose differences, the dose constraint fulfillment, or modified biomathematical treatment outcome models such as tumor control probability (TCP) and normal tissue complication probability (NTCP). An additional purpose is to establish whether the new metrics yield the same acceptance/rejection plan distribution as the conventional ones. Methods: Fifty eight treatment plans concerning several patient locations are analyzed. All of them were verified prior to the treatment, using conventional metrics, and retrospectively after the treatment with the new metrics. These new metrics include the definition of three continuous functions, based on dose-volume histograms resulting from measurements evaluated with a reconstructed dose system and also with a Monte Carlo redundant calculation. The 3D gamma function for every volume of interest is also calculated. The information is also processed to obtain ΔTCP or ΔNTCP for the considered volumes of interest. These biomathematical treatment outcome models have been modified to increase their sensitivity to dose changes. A robustness index from a radiobiological point of view is defined to classify plans in robustness against dose changes. Results: Dose difference metrics can be condensed in a single parameter: the dose difference global function, with an optimal cutoff that can be determined from a receiver operating characteristics (ROC) analysis of the metric. It is not always possible to correlate differences in biomathematical treatment outcome models with dose difference metrics. This is due to the fact that the dose constraint is often far from the dose that has an actual impact on the radiobiological model, and therefore, biomathematical treatment outcome models are insensitive to big dose differences between the verification system and the treatment planning system. As an alternative, the use of modified radiobiological models which provides a better correlation is proposed. In any case, it is better to choose robust plans from a radiobiological point of view. The robustness index defined in this work is a good predictor of the plan rejection probability according to metrics derived from modified radiobiological models. The global 3D gamma-based metric calculated for each plan volume shows a good correlation with the dose difference metrics and presents a good performance in the acceptance/rejection process. Some discrepancies have been found in dose reconstruction depending on the algorithm employed. Significant and unavoidable discrepancies were found between the conventional metrics and the new ones. Conclusions: The dose difference global function and the 3D gamma for each plan volume are good classifiers regarding dose difference metrics. ROC analysis is useful to evaluate the predictive power of the new metrics. The correlation between biomathematical treatment outcome models and the dose difference-based metrics is enhanced by using modified TCP and NTCP functions that take into account the dose constraints for each plan. The robustness index is useful to evaluate if a plan is likely to be rejected. Conventional verification should be replaced by the new metrics, which are clinically more relevant.

The transport and yield of suspended sediment (SS) in catchments all over the world have long been topics of great interest. This paper addresses the scarcity of information on SS delivery and its environmental controls in small catchments, especially in the Atlantic region. Five steep catchments in Gipuzkoa (Basque Country) with areas between 56 and 796 km
2 that drain into the Bay of Biscay were continuously monitored for precipitation, discharge and suspended sediment concentration (SSC) in their outlets from 2006 to 2013. Environmental characteristics such as elevation, slope, land-use, soil depth and erodibility of the lithology were also calculated. The analysis included consideration of uncertainties in the SSC calibration models in the final suspended sediment yield (SSY) estimations. The total delivery of sediments from the catchments into the Bay of Biscay and its standard deviation was 272 200 ± 38 107 t yr.−1 , or 151 ± 21 t km−2 yr.−1 , and the SSYs ranged from 46 ± 0.48 to 217 ± 106 t km−2 yr.−1 . Hydroclimatic variables and catchment areas do not explain the spatial variability found in SSY, whereas land-use (especially non-native plantations) and management (human impacts) appear to be the main factors that control this variability. Obtaining long-term measurements on sediment delivery would allow for the effects of environmental and human induced changes on SS fluxes to be better detected. However, the data provided in this paper offer valuable and quantitative information that will enable decision-makers to make more informed decisions on land management while considering the effects of the delivery of SS.

The mitochondrial NADH dehydrogenase complex (complex I) consists of several functional domains which independently arose during evolution. In higher plants, it contains an additional domain which includes proteins resembling gamma-type carbonic anhydrases. The Arabidopsis genome codes for five complex I-integrated gamma-type carbonic anhydrases ( γCA1, γCA2, γCA3, γCAL1, γCAL2), but only three copies of this group of proteins form an individual extra domain. Biochemical analyses revealed that the domain is composed of one copy of either γCAL1 or γCAL2 plus two copies of the γCA1/ γCA2 proteins. Thus, the carbonic anhydrase domain can have six distinct subunit configurations. Single and double mutants with respect to the γCA/ γCAL proteins were employed to genetically dissect the function of the domain. New insights into complex I biology in plants will be reviewed and discussed. [ABSTRACT FROM AUTHOR]

Objective: It is unclear whether physiologic and metabolic biomarkers are associated with chronic stressors evidenced during early childhood.Methods: Cross-sectional data were obtained from a cohort of healthy, prepubertal (Tanner stage < 2) children (n = 96; age: 8.06 [7.8] years; M = 51 [53%]; F = 45 [47%]; African-American = 26 [27%]; Caucasian = 70 [73%]; with obesity = 21 [22%]; without obesity = 75 [78%]) from the MET study. Body mass index z-score (z_BMI), total body fat (BF), visceral adipose tissue (VAT), intrahepatic and intramyocellular lipids, and insulin resistance (HOMA-IR) were measured. Chronic stress was assessed using neighborhood concentrated disadvantage index (CDI) for the U.S. Census tracts in which participants resided. Spearman's rank correlations were used to examine relationships, accounting for sex and race.Results: CDI was not positively associated with inflammatory and metabolic markers of dysfunction. However, z_BMI (-0.234, P = 0.023), BF (-0.228, P = 0.028, n = 95), and VAT (-0.241, P = 0.042, n = 74) were significantly negatively associated with CDI. When stratifying by race, these relationships remained significant in Caucasian children only.Conclusions: These findings suggest chronic stress during early childhood is not associated with inflammatory and metabolic biomarkers, typically observed in adults. Therefore, exposure to stress during this critical developmental period may remain latent and emerge during a later developmental stage. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Viral clearance during acute hepatitis C virus (HCV) infection is associated with the induction of potent antiviral T-cell responses. Since dendritic cells (DC) are essential in the activation of primary T-cell responses, gene expression was analyzed in DC from patients during acute HCV infection. By using microarrays, gene expression was compared in resting and activated peripheral blood plasmacytoid (pDC) and myeloid (mDC) DC from acute HCV resolving patients (AR) and from patients who become chronically infected (ANR), as well as in healthy individuals (CTRL) and chronically-infected patients (CHR). For pDC, a high number of upregulated genes was found in AR patients, irrespective of DC stimulation. However, for mDC, most evident differences were detected after DC stimulation, again corresponding to upregulated genes in AR patients. Divergent behavior of ANR was also observed when analyzing DC from CTRL and CHR, with ANR patients clustering again apart from these groups. These differences corresponded to metabolism-associated genes and genes belonging to pathways relevant for DC activation and cytokine responses. Thus, upregulation of relevant genes in DC during acute HCV infection may determine viral clearance, suggesting that dysfunctional DC may be responsible for the lack of efficient T-cell responses which lead to chronic HCV infection.

Background Helicobacter pylori is the primary cause of gastric cancer, but about 9% of cases harbor Epstein-Barr virus ( EBV) in the tumor cells. There is limited evidence on the possible interaction or antagonism between these infectious agents in gastric carcinogenesis. Methods We compared H. pylori serologic profiles of EBV-positive (n = 58) and EBV-negative (n = 111) noncardia gastric cancer patients from the United States National Cancer Institute's International EBV-Gastric Cancer Consortium. EBV positivity of tumors was assessed by in situ hybridization. Serum levels of 15 antibodies to immunogenic proteins of H. pylori (Cad, CagA, Cagδ, CagM, Catalase, Gro EL, HcpC, HP0231, HP0305, HpaA, HyuA, NapA, Omp, UreA, VacA) were assessed using bead-based multiplex serology. Logistic regression models were used to adjust odds ratios ( OR) for country, age, sex, and year of diagnosis. Results Seropositivity to individual proteins ranged up to 90% overall. Antibodies to Catalase were borderline associated with tumor EBV positivity (adjusted OR = 3.15, p = .0024, Bonferroni corrected p = .036). Distributions of other antibodies did not vary by tumor EBV status. Conclusion Similarity of host-response indicates the essential etiological role of H. pylori in EBV-positive gastric cancer.

The Coincidence of Reciprocal Lattice Points ( CRLP) method was used to predict, according to geometric considerations, the most favorable orientation relationships (ORs) between the component phases in a family of directionally solidified eutectic ceramics (DSEC) (NiO-YSZ, CoO-YSZ, NiO-CeO2, NiO-GDC, CoO-CeO2, and CoO-GDC) grown by the laser floating zone method. The ORs predicted by the CRLP model are consistent with those experimentally found in a previous work by means of Electron Backscatter Diffraction ( EBSD). In this article, we also present a modification to the model with the aim of taking into account that the most stable ceramic-ceramic interfaces are usually formed between atomic planes with low Miller indices, due to their higher atomic density and bigger interplanar spacing. Thus, we introduce in the calculation of the overall coincidence volume a weighting factor which is a function of the interplanar spacing. This modified CRLP method has been applied to the aforementioned eutectic ceramics, and the results are presented and discussed in comparison with the traditional CRLP results and the experimental findings.

Purpose: This work studies the relationship between in-vitro Proton Magnetic Resonance Spectroscopy metabolite quantification and water T2 decay.Materials and Methods: An in-vitro correspondence is established between the iron accumulation and the shortening of water T2 relaxation times using seven spherical phantoms, 6 of them were doped with an increasing concentration of iron metal nanoparticles solution. This is later proposed as a source of error during the LCModel metabolite quantification of either absolute concentrations or ratios.Results: The Pearson's correlation coefficient between water T2 values against absolute metabolite concentrations was on average [r] = 0.97 and on average [r] = 0.85 for metabolite ratios.Conclusion: These results suggest that the shortening of T2 values should be taken into account when performing metabolite quantification. Also, the need of demonstrated similar results in in-vivo studies, since the presence of iron deposits or other factors affecting the water T2 decay measurements could explain part of the inter-subject variability in the metabolite concentration and ratio quantification.

Aim To evaluate the impact of an interdisciplinary intervention designed to improve the capacity of nurses to manage walk-in patient demand for primary health care. Background Implementation of a programme to expand nursing practice is a complex process that requires the application of context-appropriate measures and adaptation when results do not meet expectations. Methods A longitudinal, uncontrolled intervention study with a 3-year follow-up, from 2009 to 2012, was carried out in Catalonia (northeast Spain). The intervention included three training periods focused on clinical and instrumentation topics. The capacity of nurses to manage walk-in patient demand was assessed by determining the number of cases resolved and of return visits for the same complaint within 72 hours. Results In total, 2751 patient care demands were evaluated. Resolved cases increased (χ2 = 54.624, df = 1, P < 0.001) and the number of return visits decreased (χ2 = 54.585, df = 1, P < 0.001) significantly from baseline to the end of the study period. Conclusions Nurses' capacity to manage walk-in patient demand improved after an interdisciplinary intervention using a mutually agreed upon, locally adapted approach. Implications for nursing management To improve outcomes, nurses in management positions should systematically consider the need for skills training, specific academic courses, leadership development and, as appropriate, legislative initiatives.
