Comparison between multicomponent and simultaneous dual-task exercise interventions in long-term nursing home residents: the Ageing-ONDUAL-TASK randomized controlled study.

BACKGROUND the potential benefits of dual-task interventions on older adults living in long-term nursing homes (LTNHs) from a multidimensional perspective are unknown. We sought to determine whether the addition of simultaneous cognitive training to a multicomponent exercise program offers further benefits to dual-task, physical and cognitive performance, psycho-affective status, quality of life and frailty in LTNH residents. Design: a single-blind randomized controlled trial. SETTING nine LTNHs in Gipuzkoa, Spain. SUBJECTS 85 men and women (ACTRN12618000536268). METHODS participants were randomly assigned to a multicomponent or dual-task training group. The multicomponent group performed two sessions per week of individualized and progressive strength and balance exercises for 3 months. The dual-task group performed simultaneous cognitive tasks to the same tasks as in the multicomponent group. Gait speed under single- and dual-task conditions, physical and cognitive performance, psycho-affective status, quality of life and frailty were measured at baseline and after 3 months of intervention. RESULTS both groups showed clinically significant improvements on gait performance under single- and dual-task conditions and on the short physical performance battery (P < 0.05). Both interventions were effective in maintaining cognitive function (P > 0.05). Only the multicomponent group significantly improved quality of life, and reduced anxiety and Fried frailty score (P < 0.05). No group-by-time interactions were found except for the chair-stand test in favour of the multicomponent group (P < 0.05). CONCLUSIONS the addition of simultaneous cognitive training does not seem to offer significantly greater benefits to the evaluated multicomponent exercise program in older adults living in LTNHs.
Interfering with a memory without erasing its trace

Previous research has shown that performance of a novice skill can be easily interfered with by subsequent training of another skill. We address the open questions whether extensively trained skills show the same vulnerability to interference as novice skills and which memory mechanism regulates interference between expert skills. We developed a recurrent neural network model of V1 able to learn from feedback experienced over the course of a long-term orientation discrimination experiment. After first exposing the model to one discrimination task for 3480 consecutive trials, we assessed how its performance was affected by subsequent training in a second, similar task. Training the second task strongly interfered with the first (highly trained) discrimination skill. The magnitude of interference depended on the relative amounts of training devoted to the different tasks. We used these and other model outcomes as predictions for a perceptual learning experiment in which human participants underwent the same training protocol as our model. Specifically, over the course of three months participants underwent baseline training in one orientation discrimination task for 15 sessions before being trained for 15 sessions on a similar task and finally undergoing another 15 sessions of training on the first task (to assess interference). Across all conditions, the pattern of interference observed empirically closely matched model predictions. According to our model, behavioral interference can be explained by antagonistic changes in neuronal tuning induced by the two tasks. Remarkably, this did not stem from erasing connections due to earlier learning but rather from a reweighting of lateral inhibition.
Deep-red light-up signaling of benzo[c,d]indole-quinoline monomethine cyanine for imaging of nucleolar RNA in living cells and for sequence-selective RNA analysis.

RNA-binding small probes with deep-red emission are promising for RNA analysis in the biological media without suffering from the background fluorescence. Here, benzo[c,d]indole-quinoline (BIQ), an asymmetric monomethine cyanine analogue, was newly developed as a novel RNA-selective probe with light-up signaling ability in the deep-red spectral range. BIQ features the significant light-up response (105-fold) with the emission maximum at 657 nm as well as the improved photostability over the commercially available RNA-selective probe, SYTO RNA select. BIQ was successfully applied to the fluorescence imaging of nucleoli RNAs in the living cells with negligible cytotoxicity. Furthermore, we found the useful ability of BIQ as a base surrogate integrated in the peptide nucleic acid (PNA) oligonucleotides for RNA sequence analysis. BIQ base surrogate functioned as the deep-red light-up base surrogate in forced intercalation (FIT) and triplex-forming FIT (tFIT) systems for the sequence-selective detection of single-stranded and double-stranded RNAs, respectively.
Effect of ghrelin on hypoxia-related cardiac angiogenesis: involvement of miR-210 signalling pathway

Abstract Objective Hypoxia is the main stimulus for angiogenesis. Hypoxia-inducible factor (HIF)-1α, vascular endothelial growth factor (VEGF), and miR-210 are involved in the hypoxia-induced angiogenesis. This study examined the effects of hypoxia and/or ghrelin on miR-210, HIF-1α, and VEGF levels in the heart of rats. Methods Wistar rats were randomly divided into 4 groups (n = 6): control; ghrelin, received daily intraperitoneal injections of ghrelin; hypoxia, was exposed to hypoxic condition; hypoxia + ghrelin, was exposed to hypoxic condition and received intraperitoneal injections of ghrelin, for 2 weeks. Myocardial angiogenesis, the expression level of miR-210, and protein levels of HIF-1α and VEGF were assayed in the heart samples. Results Hypoxia increased myocardial angiogenesis and cardiac levels of miR-210, HIF-1α, and VEGF. However, ghrelin inhibited these hypoxia-induced changes. Interestingly, ghrelin had no significant effect on miR-210, HIF-1α, and VEGF levels in normoxic condition. Conclusion Ghrelin may be useful as an anti-angiogenic factor.
A randomized, prospective clinical study evaluating effectiveness of a bulk-fill composite resin, a conventional composite resin and a reinforced glass ionomer in Class II cavities: one-year results

Abstract Bulk-fill restorative materials such as bulk-fill composite resins and high viscous glass ionomer cements have become very popular materials in operative dentistry because their application is easy and time-saving. Objectives: The aim of this clinical study was to evaluate the clinical performance of a highly viscous reinforced glass ionomer material, a bulk-fill composite resin and a micro hybrid composite resin in Class II restorations. Methodology: In total, 109 Class II restorations were performed in 54 patients using three different restorative materials: Charisma Smart Composite (CSC); Filtek Bulk Fill Posterior Restorative (FBF); Equia Forte Fil (EF). Single Bond Universal adhesive (3M ESPE, Germany) was used with composite resin restorations. The restorations were evaluated using modified USPHS criteria in terms of retention, color match, marginal discoloration, anatomic form, contact point, marginal adaptation, secondary caries, postoperative sensitivity and surface texture. The data were analyzed using Chi-Square, Fischer's and McNemar's tests. Results: At the end of one year, 103 restorations were followed up. No changes were observed during the first 6 months. At the end of one year, there were small changes in composite restorations (FBF and CSC) but no statistically significant difference was observed between the clinical performances of these materials for all criteria (p>0.05). However, there was a statistically significant difference between EF, FBF and CSC groups in all parameters except marginal discoloration, secondary caries and postoperative sensitivity in one-year evaluation (p<0.05). Conclusion: Bulk-fill composite resins and conventional composite resins showed more successful clinical performance than highly viscous reinforced glass ionomers in Class II cavities.
How Nurses Understand Spirituality and Spiritual Care: A Critical Synthesis

Aims: To discover how nurses understand spirituality and spiritual care and what affects nurses’ understanding of these terms. Method: A literature search was conducted in CINAHL Plus, MEDLINE, and Google Scholar for research articles dated between 2010 and 2018 that were published in English. Using the Critical Appraisal Skills Program checklist for systematic reviews, nine articles met the inclusion criteria for this review. Most of these articles reported quantitative studies. Results: Although nurses recognize the importance of spirituality and spiritual care in nursing and have ascribed a diversity of meanings, there remains some confusion about what these terms mean. Several influences have been identified as shaping nurses understanding of spirituality and spiritual care, including education, nurses’ own spirituality or religious beliefs, age, years of clinical experience, and place of employment. Conclusions: This review identifies the need for further studies using qualitative approaches to investigate how nurses’ construct their understanding of spirituality and spiritual care and the dominant discourses nurses draw from to inform their understanding using qualitative approaches. Relevance to Clinical Practice: The insights gained by this review may be of value to nurse educators, managers, and policy makers in nursing education and the development of policies and practice guidelines.
The influence of algorithms for basic-schedule generation on the performance of predictive and reactive schedules

Lately, a great deal of effort has been spent developing methods to generate robust schedules. The Multi-Objective Immune Algorithm (MOIA) is one of the methods dealing with an uncertainty [1]. The basic schedules, obtained by the MOIA, are modified using the rule of the Minimal Impact of Disturbed Operation on the Schedule (MIDOS) in order to generate predictive schedules. If the effect of a disruption is too large, in order to generate reactive schedules, the rule of the Minimal Impact of Rescheduled Operation on the Schedule (MIROS) is applied. This paper is the continuation of the searching process for an algorithm which achieves good quality basic schedules that influence on the quality of predictive and reactive schedules. In [2,3], the two immune algorithms are compared, the MOIA and Clonal Selection Algorithm (CSA) when investigating the influence of basic schedules on the obtainment of stable and robust schedules with the application of the MIDOS and MIROS. The two algorithms are applied for a multi criteria job shop scheduling problem. In this paper, the genetic algorithm (GA) is applied for the same scheduling problem and the achieved schedules are compared.
Exosomal long noncoding RNA LNMAT2 promotes lymphatic metastasis in bladder cancer.

Patients with bladder cancer (BCa) with clinical lymph node (LN) metastasis have extremely poor prognosis. VEGF-C has been demonstrated to play vital roles in LN metastasis in BCa. However, approximately 20% of BCa with LN metastasis exhibits low VEGF-C expression, suggesting a VEGF-C-independent mechanism for LN metastasis of BCa. Herein, we demonstrated that BCa cell-secreted exosomes-mediated lymphangiogenesis promoted LN metastasis in BCa, which was in a VEGF-C-independent manner. We identified an exosomal long noncoding RNA (lncRNA), termed lymph node metastasis-associated transcript 2 (LNMAT2), stimulated HLEC tube formation and migration in vitro and enhanced tumor lymphangiogenesis and LN metastasis in vivo. Mechanistically, LNMAT2 was loaded to BCa cell-secreted exosomes by directly interacting with heterogeneous nuclear ribonucleoprotein A2B1 (hnRNPA2B1). Subsequently, exosomal LNMAT2 was internalized by HLECs and epigenetically upregulated prospero homeobox 1 (PROX1) expression by recruitment of hnRNPA2B1 and increasing the H3K4 trimethylation level in the PROX1 promoter, ultimately resulting in lymphangiogenesis and lymphatic metastasis. Therefore, our findings highlight a VEGF-C-independent mechanism of exosomal lncRNA-mediated LN metastasis and identify LNMAT2 as a therapeutic target for LN metastasis in BCa.
Does Reducing Sedentarity With Standing Desks Hinder Cognitive Performance?

Objective The goal of this study was to determine if using a standing desk would affect the productivity of workers, based on the type of work they perform. Background Standing desks are a promising new health intervention in the workplace, but users and employers often require more specific recommendations related to productivity, such as the type of work that is more suited for the standing desk. Method Thirty-seven young and healthy adults performed eight cognitive tasks in a 2 × 2 × 2 within-subject design of the following independent variables: posture (sitting/standing), task difficulty (easy/hard), and input device (computer mouse/tactile screen) in a counterbalanced order. Results Our results revealed that using a standing desk had no negative effect on performance or perception, but it did lead to increased brain activity in the alpha band for the parietal region (β = 0.186, p = .001). Conclusion We conclude that users of standing desks can freely stand for any level of task difficulty for work that involves working memory. However, more research is needed to generalize these results to other types of cognitive abilities and prolonged use of standing desks. Application Our results simplify recommendations for workers as they do not need to worry about the type of work they are performing when using a standing desk.
Action Production and Event Perception as Routine Sequential Behaviors

It is argued that event perception and routine sequential action production share a range of characteristics (e.g., similar levels of automaticity, the involvement of sequentially and hierarchically organized schemata, and the coupled operation of predictive and monitoring processes). With this in mind, and in an effort to develop a mechanistic account of event perception, we consider how an existing model of routine sequential action production might be applied in the domain of event perception. We focus the discussion on the multiple roles of prediction in the two domains, and we consider the implications of the application of the model of action production to event perception and for sequential processing more generally.
The time course of anaphylaxis manifestations in children is diverse and unpredictable

The most current clinical definition of anaphylaxis is that proposed by Sampson et al. and different scoring systems have been proposed to assess its severity [1,2]. Anaphylaxis symptoms range from mild, self-limiting local reactions to life-threatening anaphylaxis. All anaphylaxis guidelines emphasize early recognition and the need for prompt intramuscular adrenaline injection as the first-line treatment [3]. However, adrenaline for anaphylaxis is underused by patients, families and even by health professionals. In the European anaphylaxis registry, 27% of patients treated by a health professional received adrenaline [4].
Online survey to assess parents’ experience and preferences for follow-up visits for children living with type 1 diabetes in Quebec, Canada: a study protocol

Introduction It is accepted that although patients may initiate a visit to a healthcare provider, follow-up visits are often based on recommendations from providers. This suggests that follow-up care, since not initiated by patients, may not reflect patients’ perception of a need for care. However, few studies have examined the burden of regular follow-up care and patients’ perceived value of such care. For parents of children with type 1 diabetes (T1D), follow-up visits are scheduled regardless of how well controlled the diabetes is. Our study examines how benefits and burden from the parents’ perspective could affect their preferences in regard to the frequency of regular follow-up care. Methods We aim to develop an online patient survey to be distributed to parents of children living with T1D in the province of Quebec, Canada. The survey will be available in French and English, and distributed through diabetes clinics, on social media groups and forums for parents of children with T1D. The survey will be developed in collaboration with parents of children with T1D to ensure that it appropriately reflects the services in regular follow-up care and that the language is understandable and clear. Ethics and dissemination All participants will be informed of the requirements and objectives of the survey at the beginning of the questionnaire and that the data collected will remain anonymous and confidential. Ethics approval for the study was obtained from the research ethics committee of the CHU de Québec-Université Laval. Results of the study will be shared with relevant stakeholders with the aim of improving practices and better meeting patients’ and families’ needs.
Longitudinal assessment of alpha-fetoprotein for early detection of hepatocellular carcinoma in patients with cirrhosis

Abstract Background/aims: Cirrhosis is an important risk factor for hepatocellular carcinoma (HCC), and the surveillance of patients with cirrhosis is, therefore, highly recommended. However, the role of alpha-fetoprotein (AFP) in HCC surveillance is controversial. The aim of this study was to determine the role of AFP in HCC surveillance among patients with cirrhosis. Methods: The study population consisted of 392 patients with cirrhosis. Ultrasound (US) and laboratory tests including AFP were regularly performed to detect HCC development. The cutoff level of AFP for suspicion of HCC was 7 ng/mL. Results: During the median follow-up period of 4.7 (interquartile range, 3.4–5.6) years, HCC developed in 64 (16.3%) patients. Their mean age was 53.6 years, and they were predominantly male (63.5%). For the detection of HCCs, the sensitivity and specificity of US were 56.3% and 100%, respectively. The sensitivity and specificity of AFP were 62.5% and 94.5%, respectively. Using US and AFP in combination increased the sensitivity of surveillance to 89.1% with a specificity of 94.5%. Mean AFP levels were significantly higher in patients with than without HCC at the time of HCC diagnosis, at 6 months and 12 months before the diagnosis. The area under the receiver operating characteristic curve of AFP was highest at the time of HCC diagnosis (0.867), and also was acceptable at 6 months (0.823) and 12 months (0.792) before the diagnosis. Conclusions: These results suggest the complementary use of AFP and US to improve the effectiveness of HCC surveillance in patients with cirrhosis.
ALDH1A1‐related stemness in high‐grade serous ovarian cancer is a negative prognostic indicator but potentially targetable by EGFR/mTOR‐PI3K/aurora kinase inhibitors

Poor chemotherapy response remains a major treatment challenge for high‐grade serous ovarian cancer (HGSC). Cancer stem cells are the major contributors to relapse and treatment failure as they can survive conventional therapy. Our objectives were to characterise stemness features in primary patient‐derived cell lines, correlate stemness markers with clinical outcome and test the response of our cells to both conventional and exploratory drugs. Tissue and ascites samples, treatment‐naive and/or after neoadjuvant chemotherapy, were prospectively collected. Primary cancer cells, cultured under conditions favouring either adherent or spheroid growth, were tested for stemness markers; the same markers were analysed in tissue and correlated with chemotherapy response and survival. Drug sensitivity and resistance testing was performed with 306 oncology compounds. Spheroid growth condition HGSC cells showed increased stemness marker expression (including aldehyde dehydrogenase isoform I; ALDH1A1) as compared with adherent growth condition cells, and increased resistance to platinum and taxane. A set of eight stemness markers separated treatment‐naive tumours into two clusters and identified a distinct subgroup of HGSC with enriched stemness features. Expression of ALDH1A1, but not most other stemness markers, was increased after neoadjuvant chemotherapy and its expression in treatment‐naive tumours correlated with chemoresistance and reduced survival. In drug sensitivity and resistance testing, five compounds, including two PI3K‐mTOR inhibitors, demonstrated significant activity in both cell culture conditions. Thirteen compounds, including EGFR, PI3K‐mTOR and aurora kinase inhibitors, were more toxic to spheroid cells than adherent cells. Our results identify stemness markers in HGSC that are associated with a decreased response to conventional chemotherapy and reduced survival if expressed by treatment‐naive tumours. EGFR, mTOR‐PI3K and aurora kinase inhibitors are candidates for targeting this cell population. © 2019 Pathological Society of Great Britain and Ireland. Published by John Wiley & Sons, Ltd.
Maintenance of Complex Life Cycles Via Cryptic Differences In The Ecophysiology Of Haploid And Diploid Spores Of An Isomorphic Red Alga1

Recognition of the wide diversity of organisms that maintain complex haploid–diploid life cycles has generated interest in understanding the evolution and persistence of such life cycles. We empirically tested the model where complex haploid–diploid life cycles may be maintained by subtle/cryptic differences in the vital rates of isomorphic haploid–diploids, by examining the ecophysiology of haploid tetraspores and diploid carpospores of the isomorphic red alga Chondrus verrucosus. While tetraspores and carpospores of this species did not differ in size or autofluorescence, concentrations of phycobiliproteins of carpospores were greater than that of tetraspores. However, tetraspores were more photosynthetically competent than carpospores over a broader range of photosynthetic photon flux densities (PPFDs) and at PPFDs found at both the depth that C. verrucosus is found at high tide and in surface waters in which planktonic propagules might disperse. These results suggest potential differences in dispersal potential and reproductive success of haploid and diploid spores. Moreover, these cryptic differences in ecological niche partitioning of haploid and diploid spores contribute to our understanding of some of the differences between these ploidy stages that may ultimately lead to the maintenance of the complex haploid–diploid life cycle in this isomorphic red alga.
Targeted fusion analysis can aid in the classification and treatment of pediatric glioma, ependymoma, and glioneuronal tumors

The use of next‐generation sequencing for fusion identification is being increasingly applied and aids our understanding of tumor biology. Some fusions are responsive to approved targeted agents, while others have future potential for therapeutic targeting. Although some pediatric central nervous system tumors may be cured with surgery alone, many require adjuvant therapy associated with acute and long‐term toxicities. Identification of targetable fusions can shift the treatment paradigm toward earlier integration of molecularly targeted agents.
Ten common statistical mistakes to watch out for when writing or reviewing a manuscript

Inspired by broader efforts to make the conclusions of scientific research more robust, we have compiled a list of some of the most common statistical mistakes that appear in the scientific literature. The mistakes have their origins in ineffective experimental designs, inappropriate analyses and/or flawed reasoning. We provide advice on how authors, reviewers and readers can identify and resolve these mistakes and, we hope, avoid them in the future.
