    Gd-DTPA enhanced T1 weighted MRI is a discriminating test for a defective blood-brain barrier, with MS lesions showing considerable variation in the pattern of enhancement. Since little is known of the changes in the blood-brain barrier in the active plaque over time, the natural history of blood-brain barrier disturbance in the MS lesion was examined to confirm earlier reports that Gd-DTPA enhancement is a consistent early event in new lesions of relapsing/remitting MS. This knowledge is essential for the use of MRI in monitoring treatment. (author). 9 refs

    Within the multidisciplinary team required to manage people with multiple sclerosis (MS) effectively, the nurse is the central component of coordinated care and support. A 2009 survey led by the European Multiple Sclerosis Platform, an umbrella organization of national MS associations, identified variance and disparity across Europe in the nursing care of MS patients. This led to development of MS Nurse PROfessional, a continuing medical education-accredited modular online learning program endorsed and approved by leading international nursing and professional groups, and people with MS, as a tool to support the evolving role of the European MS nurse. Analysis of participant experience and nurse practice to date has been overwhelmingly positive. Expansion of MS Nurse PRO is underway or planned for future.

    The purpose of the study reported here was to describe Finnish nurses' research and publication activities, as well as their views on the availability and utilization of research results in nursing practice. The data were collected using a structured questionnaire in which obstacles to the utilization of research results were measured with a previously developed instrument. A total of 400 nurses from community health centres, a central hospital and a central university hospital took part. Most of the nurses had carried out research on their own. Age, experience, training in research and development and other further training, as well as reading the nursing literature, were associated with doing research. Some of the reasons why the nurses had not carried out research were revealed. Publication of results was very rare. There were problems with the availability of research results. The most common obstacles to research utilization had to do with the presentation of results and the setting. In research utilization, respondents received most support from the ward manager and least support from doctors. If we want to encourage nurses to do research and increase the utilization of research results, greater effort should be invested in teaching research methodology, in introducing more flexible working hours and in developing other support systems.

    Are home nurses (also known as community nurses) ready for their changing role in primary care? A quantitative study was performed in home nursing in Flanders, Belgium, to explore the activity profile of home nurses and health care assistants, using the 24-hour recall instrument for home nursing. Seven dates were determined, covering each day of the week and the weekend, on which data collection would take place. All the home nurses and health care assistants from the participating organisations across Flanders were invited to participate in the study. All data were measured at nominal level. A total of 2478 home nurses and 277 health care assistants registered 336 128 (47 977 patients) and 36 905 (4558 patients) activities, respectively. Home nurses and health care assistants mainly perform 'self-care facilitation' activities in combination with 'psychosocial care' activities. Health care assistants also support home nurses in the 'selfcare facilitation' of patients who do not have a specific nursing indication.

    Canadian nurses have a social mandate to address health inequities for the populations they serve, as well as to speak out on professional and broader social issues. Although Canadian nursing education supports the role of nurses as advocates for social justice and leadership for health care reform, little is known about how nurse educators understand activism and how this translates in the classroom. A comparative life history study using purposeful sampling and a critical feminist lens was undertaken to explore political activism in nursing and how nurse educators foster political practice among their students. Findings from interviews and focus groups with 26 Ontario nurse educators and nursing students suggested that neoliberal dynamics in both the practice setting and in higher education have constrained nurses' activist practice and favour a technical rational approach to nursing education. Implications and strategies to inspire political action in nursing education are discussed.

    This article is a report of a study to examine how nursing staff spend their time on activities in a nursing home. Few studies have investigated how nursing staff spend their time on activities in a nursing home. Such information is important for nurse managers in deciding on staff deployment, and for evaluating the effects of changes in nursing practice. A work sampling study with an observational component was undertaken in 2009 with nursing staff at a nursing home. A total of 430 activities were recorded for Registered Nurses, 331 for Endorsed Enrolled Nurses, 5276 for Personal Carers, and 501 for Recreational Activity Officers. Registered Nurses spent 48·4% of their time on communication and 18·1% on medication management. Endorsed Enrolled Nurses spent 37·7% on communication and 29·0% on documentation tasks. Communication was the most time-consuming activity for Recreational Activity Officers and Personal Carers, except that Personal Carers in a high care house spent more time on direct care duties. Hygiene duties and resident interaction were more frequently multitasked by the nursing staff in high care than in low care house. Nursing staff value their face-to-face interaction for successful care delivery. There is need, however, to investigate the effects of this form of communication on quality of care given to residents. Differences in multi-tasked activities between high care and low care houses should be considered when deploying staff in a nursing home. © 2011 Blackwell Publishing Ltd.

    There has been limited research to document differences in roles between nurses and non-nurses who assume clinical research coordination and management roles. Several authors have suggested that there is no acknowledged guidance for the licensure requirements for research study coordinators and that some non-nurse research coordinators may be assuming roles that are outside of their legal scopes of practice. There is a need for further research on issues related to the delegation of clinical research activities to non-nurses. This study used nominal group process focus groups to identify perceptions of experienced research nurse managers at an academic health science center in the Southern United States about the clinical research activities that are being performed by non-nurse clinical research coordinators without supervision that they believed should only be performed by a nurse or under the supervision of a nurse. A total of 13 research nurse managers volunteered to be contacted about the study. Of those, 8 participated in two separate nominal group process focus group sessions. The group members initially identified 22 activities that they felt should only be performed by a nurse or under the direct supervision of a nurse. After discussion and clarification of results, activities were combined into 12 categories of clinical research activities that participants believed should only be performed by a nurse or under the direct supervision of a nurse.

    Full Text Available Costs of human resources include a high percentage of hospital’s costs; therefore, determination of number of real and optimal employees needed for organizations is very important. In the meantime, the optimal organization of nurses, as the biggest human resource in health care organizations, is of great importance. The present study aimed to assess the distribution of nurses’ activities in shifts and the results of productivity in human resources management in Imam Khomeini hospital in Shirvan. The present cross-sectional study was conducted in 2016. All nurses, working in three shifts of morning, afternoon, and evening in emergency unit and general units of Imam Khomeini hospital, Shirvan, were enrolled into the study through census methods. The instrument, used in this study, was the checklist of timing activities and patients’ satisfaction from nurses. The statistical software SPSS was used for analysis. Mean age of employees in these two units/wards was 31 years and mean duration of work experience was 5.24 years, The difference was significant between the two wards. necessity of the work, especially in emergency unit, are issues that need more assessment and need to be adjusted. Given the high volume of non-care matters of nursing staff, including writing services, including completing paper records and work with HIS (Hospital Information System, which has been emphasized in several studies, new definition of service and use of artificial intelligence with high efficacy is proposed. The status of the available equipment, availability, and efficiency of digital equipment and hoteling state of wards and hospitals also play an important factor in the distribution of time of nursing care activities. Employment of nurses to perform non-nursing duties, because of the shortage of other classes or lack of their permanent presence and based on Although there were differences in standard time of direct and indirect care in emergency unit and

    Endocrine active substances, including naturally occurring hormones and various synthetic chemicals have received much concern owing to their endocrine disrupting potencies. It is essential to monitor their environmental occurrence since these compounds may pose potential threats to biota and human health. In this study, yeast-based reporter assays were carried out to investigate the presence of (anti-)androgenic, (anti-)estrogenic, and (anti-)thyroid compounds in the aquatic environment in southern Taiwan. Liquid chromatography tandem mass spectrometry (LC-MS/MS) was also used to measure the environmental concentrations of selected endocrine active substances for assessing potential ecological risks and characterizing contributions to the endocrine disrupting activities. Bioassay results showed that anti-androgenic (ND-7489 μg L(-1) flutamide equivalent), estrogenic (ND-347 ng L(-1) 17β-estradiol equivalent), and anti-thyroid activities were detected in the dissolved and particulate phases of river water samples, while anti-estrogenic activities (ND-10 μg L(-1) 4-hydroxytamoxifen equivalent) were less often found. LC-MS/MS analysis revealed that anti-androgenic and estrogenic contaminants, such as bisphenol A, triclosan, and estrone were frequently detected in Taiwanese rivers. In addition, their risk quotient values were often higher than 1, suggesting that they may pose an ecological risk to the aquatic biota. Further identification of unknown anti-androgenic and estrogenic contaminants in Taiwanese rivers may be necessary to protect Taiwan's aquatic environment. Copyright © 2016 Elsevier Ltd.

    To develop a theoretical understanding of factors that impact decisions of clinical nurses to conduct a research study. Only a small percentage of all nurses are research-active and even fewer clinical nurses are research-active. Several researchers have explored barriers to research activity by clinical nurses, but few have examined why, in spite of all odds, some clinical nurses are research-active. As the purpose of this study was to develop a theoretical understanding of the research-active nurse, a grounded theory approach was used. The sample interviewed for this study consisted of registered nurses (n = 26) who worked in a hospital or ambulatory setting, had daily direct patient contact and had participated as principal investigator on at least one completed clinical nursing research study that was not in fulfilment of an educational requirement. The interviews were digitally recorded and analysed by two researchers using the constant comparative method. The findings from this study suggest that the conduct of research by clinical nurses was the direct result of a clinical trigger, characteristics and beliefs of the nurse about research and their role in generating knowledge, and the presence of support conditions, such as a research mentor. Clinical nurses can and do conduct research, in spite of constraints due to a lack of time, money and/or knowledge, if they have access to research mentors and are practising in a research-supportive environment. Nurses at the bedside are in a unique position to identify problems most in need of solutions. Findings from this study provide a foundation upon which to develop and test various programmes that seek to increase the number of clinical nurses who are research-active. © 2016 John Wiley & Sons Ltd.

    20(R)-25-methoxyl-dammarane-3β,12β,20-triol (25-OCH3-PPD) is a promising antitumor compound belonging to triterpenoid saponins isolated from radix notoginseng. A systematic research on the related impurities in raw material of 25-OCH3-PPD has not been conducted. In this study, three impurities obtained by HPLC-ELSD and characterized by (13)C NMR and MS were observed in the raw material of 25-OCH3-PPD. Cytotoxic activities of the related substances were also evaluated, of which impurity B with 25-OCH3-PPD showed synergistic inhibitory activity against BGC-823 with IC50 values of 8.33μM. Furthermore, a rapid and selective UPLC-MS/MS method was developed for simultaneous determination of the principal component and three related substances in the raw material of 25-OCH3-PPD. Multiple reaction monitoring scan mode was used for the quantification of 20(R)-25-OCH3-PPD and its three related substances. The four constituents were separated within 11min on a BEH C18 column (100 mm×2.1mm, 1.7μm) using a mobile phase comprising methanol and 0.03% formic acid water (82:18, v/v) at a flow rate of 0.2mL/min. The proposed UPLC-MS/MS method displayed acceptable levels of linearity, precision, repeatability, and accuracy. In addition, the proposed method was successfully applied for the establishment of a rational quality control standard for the raw material of 25-OCH3-PPD. Copyright © 2016 Elsevier B.V.

    No studies quantify the labor market disparities between nurses with and without activity difficulties (physical impairment or disability). We explore disparate treatment of nurses with activity difficulties at three margins of the labor market: the ability to get a job, the relative wage rate offered once a nurse has a job, and the annual hours of work given that wage rate. Key variables from the American Community Survey (ACS) were analyzed, including basic demographic information, wages, hours of work, and employment status of registered nurses from 2006 to 2014. Although there is relatively little disparity in hourly wages, there is enormous disparity in the disabled's employment and hours of work opportunities, and hence a moderate amount of disparity in annual wages. This has significant implications for the nursing labor force, particularly as the nursing workforce continues to age and physical limitations or disabilities increase by 15-fold from 25 to 65 years of age.  Physical or psychological difficulties increase sharply over the course of a nurse's career, and employers must heighten efforts to facilitate an aging workforce and provide appropriate job accommodations for nurses with activity limitations. © 2016 Sigma Theta Tau International.

    To describe the physical activity (PA) promotion practices, beliefs, and barriers of Australasian oncology nurses and gain preliminary insight into how PA promotion practices may be affected by the demographics of the nurses.
. Cross-sectional survey.
. Australia and New Zealand.
. 119 registered oncology nurses.
. Self-reported online survey completed once per participant.
. Questions assessed the PA promotion beliefs (e.g., primary healthcare professionals responsible for PA promotion, treatment stage), PA benefits (e.g., primary benefits, evidence base), and PA promotion barriers of oncology nurses.
. Oncology nurses believed they were the major providers of PA advice to their patients. They promoted PA prior to, during, and post-treatment. The three most commonly cited benefits of PA for their patients were improved quality of life, mental health, and activities of daily living. Lack of time, lack of adequate support structures, and risk to patient were the most common barriers to PA promotion. Relatively few significant differences in the oncology nurses' PA promotion practices, beliefs, and barriers were observed based on hospital location or years of experience.
. Despite numerous barriers, Australasian oncology nurses wish to promote PA to their patients with cancer across multiple treatment stages because they believe PA is beneficial for their patients.
. Hospitals may need to better support oncology nurses in promoting PA to their patients and provide better referral pathways to exercise physiologists and physiotherapists.

    Nursing performance measures are an integral part of quality initiatives in acute care; however, organizations face numerous challenges in developing infrastructures to support quality improvement processes and timely dissemination of outcomes data. At the Hospital of the University of Pennsylvania, a Magnet-designated organization, extensive work has been conducted to incorporate nursing-related outcomes in the organization's quality plan and to integrate roles for clinical nurses into the Department of Nursing and organization's core performance-based programs. Content and strategies that promote active involvement of nurses and prepare them to be competent and confident stakeholders in quality initiatives are presented. Engaging clinical nurses in the work of quality and performance improvement is essential to achieving excellence in clinical care. It is important to have structures and processes in place to bring meaningful data to the bedside; however, it is equally important to incorporate outcomes into practice. When nurses are educated about performance and quality measures, are engaged in identifying outcomes and collecting meaningful data, are active participants in disseminating quality reports, and are able to recognize the value of these activities, data become one with practice.

    2014-07-01

    Supervised exercise training has substantial benefits for persons with multiple sclerosis (MS), yet 80% of those with MS do not meet recommended levels of moderate-to-vigorous physical activity (MVPA). This same problem persisted for decades in the general population of adults and prompted a paradigm shift away from "exercise training for fitness" toward "physical activity for health." The paradigm shift reflects a public health approach of promoting lifestyle physical activity through behavioral interventions that teach people the skills, techniques, and strategies based on established theories for modifying and self-regulating health behaviors. This paper describes: (a) the definitions of and difference between structured exercise training and lifestyle physical activity; (b) the importance and potential impact of the paradigm shift; (c) consequences of lifestyle physical activity in MS; and (d) behavioral interventions for changing lifestyle physical activity in MS. The paper introduces the "new kid on the MS block" with the hope that lifestyle physical activity might become an accepted partner alongside exercise training for inclusion in comprehensive MS care. © The Author(s) 2014.

    The purpose of this study was to explore self-identified motivators for regular physical activity among ambulatory nursing home older residents. A qualitative exploratory design was adopted. Purposive sampling was performed to recruit 18 older residents from two nursing homes in Taiwan. The interview transcripts were analyzed by qualitative content analysis. Five motivators of physical activity emerged from the result of analysis: eagerness for returning home, fear of becoming totally dependent, improving mood state, filling empty time, and previously cultivated habit. Research on physical activity from the perspectives of nursing home older residents has been limited. An empirically grounded understanding from this study could provide clues for promoting and supporting lifelong engagement in physical activity among older residents. The motivators reported in this study should be considered when designing physical activity programs. These motivators can be used to encourage, guide, and provide feedback to support older residents in maintaining physical activity.

    Engagement in social and leisure activities is an indicator of quality of life and well-being in nursing homes. There are few studies in which nursing home residents with dementia self-reported their experiences in activity engagement. This qualitative study describes types of current activity involvement and barriers to activities as perceived by nursing home residents with dementia. Thirty-one residents participated in short, open-ended interviews and six in in-depth interviews. Thematic content analysis showed that participants primarily depended on activities organized by their nursing homes. Few participants engaged in self-directed activities such as walking, visiting other residents and family members, and attending in church services. Many residents felt they had limited opportunities and motivation for activities. They missed past hobbies greatly but could not continue them due to lack of accommodation and limitation in physical function. Environmental factors, along with fixed activity schedule, further prevented them from engaging in activities. Residents with dementia should be invited to participate in activity planning and have necessary assistance and accommodation in order to engage in activities that matter to them. Based on the findings, a checklist for individualizing and evaluating activities for persons with dementia is detailed. PMID:25489122

    Telehealth is viewed as a major strategy to address the increasing demand for care and a shrinking care professional population. However, most nurses are not trained or are insufficiently trained to use these technologies effectively. Therefore, the potential of telehealth fails to reach full utilization. A better understanding of nursing telehealth entrustable professional activities (NT-EPAs) and the required competencies can contribute to the development of nursing telehealth education. In a four-round Delphi-study, a panel of experts discussed which NT-EPAs are relevant for nurses and which competencies nurses need to possess to execute these activities effectively. The 51 experts, including nurses, nursing faculty, clients and technicians all familiar with telehealth, were asked to select items from a list of 52 competencies based on the literature and on a previous study. Additionally, the panelists could add competencies based on their experience in practice. The threshold used for consensus was set at 80%. Consensus was achieved on the importance of fourteen NT-EPAs, requiring one or more of the following core competencies; coaching skills, the ability to combine clinical experience with telehealth, communication skills, clinical knowledge, ethical awareness, and a supportive attitude. Each NT-EPA requires a specific set of competencies (at least ten). In total, 52 competencies were identified as essential in telehealth. Many competencies for telehealth, including clinical knowledge and communication skills, are not novel competencies. They are fundamental to nursing care as a whole and therefore are also indispensable for telehealth. Additionally, the fourteen NT-EPAs appeared to require additional subject specific competencies, such as the ability to put patients at ease when they feel insecure about using technology. The NT-EPAs and related competencies presented in this study can be used by nursing schools that are considering including or expanding

    The aim of this study was to evaluate whether active intervention can decrease job burnout and improve performance among ED nurses. This study was carried out in the emergency departments of 3 hospitals randomly selected from 8 comprehensive high-level hospitals in Jinan, China. A total of 102 nurses were enrolled and randomly divided into control and intervention groups. For 6 months, nurses in intervention groups were treated with ordinary treatment plus comprehensive management, whereas nurses in the control group were treated with ordinary management, respectively. Questionnaires were sent and collected at baseline and at the end of the study. The Student t test was used to evaluate the effect of comprehensive management in decreasing burnout.

    Analyze the challenges and strategies of nurses performing managerial activities in a surgical center. Exploratory, descriptive study with a qualitative approach, involving six nurses by means of the Focus Group Technique, between April and August 2013. Data were submitted to thematic content analysis. The main challenges noted were deficiency of material resources, communication noise, adequacy of personnel downsizing, and relationships with the multidisciplinary team. Key strategies include construction of co-management spaces to promote integration among professionals, conflict resolution and exchange of knowledge. Managerial activities involve the promotion of dialogic moments to coordinate the different processes in the surgical center to provide inputs to expand safety and quality of services provided.

    The growing market of herbal remedies worldwide could pose severe problems to consumers' health due to the possible presence of potentially harmful, undeclared synthetic substances or analogues of prescription drugs. The present work shows a simple but effective approach to unequivocally identify synthetic anorectic compounds in allegedly 'natural' herbal extracts, by exploiting liquid chromatography/time of flight (Q-TOF LC/MS) technology coupled to liquid chromatography/triple quadrupole (LC-MS/MS) confirmation and quantitation. The procedure was applied to five tea herbal extracts and pills sold as coadjutant for weigh loss. The method exploited liquid-liquid sample extraction (LLE) and separation in a C18 (2.1mm×150mm, 1.8μm) column. QTOF acquisitions were carried out both in scan mode and all ion MS/MS mode and results were obtained after search against ad hoc prepared library. Sibutramine, 4-hydroxyamphetamine, caffeine and theophylline were preliminary identified samples. Confirmation and quantitation of the preliminary identified compounds were obtained in LC-MS/MS after preparation of appropriated standards. Sibutramine, caffeine and theophylline were finally confirmed and quantitate. Copyright © 2018 Elsevier B.V. All rights reserved.

    Background Although nurses play an important role in humanitarian aid and disaster relief (HA/DR), little is known about the nursing activities that are performed in HA/DR. We aimed to clarify the nursing activities performed by Japanese nurses in HA/DR and to examine the factors associated with the frequency of nursing activities. Methods A self-administered questionnaire survey was completed by 147 nurses with HA/DR experience. The survey extracted information on demographic characteristics, past experience (e.g., disaster medical training experience, HA/DR experience), circumstances surrounding their dispatched to HA/DR (e.g., team size, disaster type, post-disaster phase, mission term), and the frequency of nursing activities performed under HA/DR. The frequency of nursing activities was rated on a 5-point Likert scale. Evaluation of nursing activities was conducted based on the “nursing activity score”, which represents the frequency of each nursing activity. Factors related to the nursing activity score were evaluated by multiple logistic regression analysis. Results Nurses were involved in 27 nursing activities in HA/DR, 10 of which were performed frequently. On analysis, factors significantly associated with nursing activity score were nursing license as a registered nurse (OR 7.79, 95% CI 2.95–20.57), two or more experiences with disaster medical training (OR 2.90 95%, CI 1.12–7.49) and a post-disaster phase of three weeks or longer (OR 8.77, 95% CI 2.59–29.67). Conclusions These results will contribute to the design of evidence-based disaster medical training that improves the quality of nursing activities. PMID:26959351

    To identify factors influencing research activity of Andalusian nurses and to find improvement strategies. Qualitative research using SWOT analysis (weaknesses, threats, strengths, opportunities). Nurses were selected deliberately in eight groups according to predetermined criteria. Analysis included categorization and relationship of factors and strategies. 81 participants were included in groups of 7-12 range. 45 categories were identified with 212 factors: 12 weaknesses (50 factors), 10 strengths (44 factors), 12 threats (68 factors) and 11 opportunities (50 factors). In addition, 32 categories were identified with 53 strategies: 14 categories of W-T strategies (42 strategies), 3 categories of S-T strategies (11 strategies), 5 categories of W-O strategies (13 strategies) and 10 categories of S-O strategies (41 strategies). Nurses identified numerous factors, mainly threats. The strategies are focused on W-T but they also suggest many but weak 5-0 strategies due to the low potential of the opportunities and strengths perceived.

    Full Text Available Background: The role of physical activity (PA in the prevention and treatment of civilization diseases has been recognized by the medical society. Despite extensive knowledge and well-documented evidence of health aspects of PA, the identification and assessment of the PA level in various social and professional groups are still needed. The main goal of this research was to work out a preliminary assessment of possible relationship between recreational physical activity and reduced common musculoskeletal disorders in nurses. Material and Methods: The study included 93 nurses, aged 41.4±7.31, with body height of 164.4±7.04 and body weight of 64.5±10.8. The Nordic Musculoskeletal Questionnaire (NMQ was applied to assess pain and the International Physical Activity Questionnaire (IPAQ (long version to assess the level of physical activity. The intergroup differences, due to the occurrence of pain and physical activity levels, were determined using the Mann Whitney test and the Kruskal Wallis test. To evaluate the significance of individual factors potentially influencing the onset of musculoskeletal pains, the Chi2 test for independence was performed. Results: Over 70% of the examined nurses reported musculoskeletal complaints, mostly related with lower back pain. Taking up recreational activity, of at least moderate to vigorous physical activity (MVPA, reduces the risk of musculoskeletal disorders. Conclusion: It is most likely that recreational physical activity at appropriate parameters may prevent musculoskeletal disorders, especially in nurses with long work experience. However, this hypothesis needs to be verified by experimental studies with use of objective tools for the assessment of physical activity. Med Pr 2014;65(2:181–188

    Full Text Available Lotus (Nelumbo nucifera leaves, a traditional Chinese medicinal herb, are rich in flavonoids. In an effort to thoroughly analyze their flavonoid components, macroporous resin chromatography coupled with HPLC-MS/MS was employed to simultaneously enrich and identify flavonoids from lotus leaves. Flavonoids extracted from lotus leaves were selectively enriched in the macroporous resin column, eluted subsequently as fraction II, and successively subjected to analysis with the HPLC-MS/MS and bioactivity assays. Altogether, fourteen flavonoids were identified, four of which were identified from lotus leaves for the first time, including quercetin 3-O-rhamnopyranosyl-(1→2-glucopyranoside, quercetin 3-O-arabinoside, diosmetin 7-O-hexose, and isorhamnetin 3-O-arabino- pyranosyl-(1→2-glucopyranoside. Further bioactivity assays revealed that these flavonoids from lotus leaves possess strong antioxidant activity, and demonstrate very good potential to be explored as food supplements or even pharmaceutical products to improve human health.

    There is strong evidence that suggests physical activity can enhance mental well-being. However, this relationship has not been widely investigated in student nurses. A cross-sectional study was conducted to examine the relationship between physical activity and mental well-being in undergraduate student nurses (n=215). Physical activity was measured using the International Physical Activity Questionnaire. Other outcomes included self-esteem, anxiety, depression, life satisfaction, outcome expectations and self-efficacy. Almost, a quarter (23.8%) of the total sample, were meeting the Department of Health's physical activity guideline. Mean body mass index (BMI) was 25.0 with 40% being in the overweight to morbidly obese category. Self-esteem was significantly positively correlated with total physical activity (r=0.16, p=0.038) and moderate intensity activity (r=0.17, p=0.021). No other significant relationships were found between anxiety, depression and satisfaction with life and physical activity. Outcome expectations for exercise and self-efficacy were significantly positively correlated with moderate (r=0.17, p=0.019) and vigorous (r=0.28, p=0.000) intensity activity and total physical activity (r=0.29, p=0.000). BMI was significantly positively correlated with age (r=0.242, p=0.001), significantly negatively correlated with self-efficacy for exercise (r=0.257, p=0.000) and satisfaction with life (r=-0.144, p=0.041). Regression analysis showed that low self efficacy for exercise and increasing age were significant predictors of BMI with a small effect size r(2)=0.126, adjusted r(2)=0.112. BMI and physical activity variables collectively explained only 2% of the variance for anxiety, 4% for depression, 5% for self esteem and 6% for satisfaction with life. BMI was a significant predictor of satisfaction with life (Beta=-0.171, p=0.027). Participation in physical activity may be influential in improving mental well-being in student nurses.

    2-Arachidonoyl glycerol (2AG) is an endocannabinoid that activates cannabinoid (CB) receptors CB1 and CB2. Monoacylglycerol lipase (MAGL) inactivates 2AG through hydrolysis to arachidonic acid (AA) and glycerol, thus modulating the activity at CB receptors. In the brain, AA released from 2AG by the action of MAGL serves as a substrate for cyclooxygenases which produce pro-inflammatory prostaglandins. Here we report stable-isotope GC-MS and LC-MS/MS assays for the reliable measurement of MAGL activity. The assays utilize deuterium-labeled 2AG (d 8 -2AG; 10μM) as the MAGL substrate and measure deuterium-labeled AA (d 8 -AA; range 0-1μM) as the MAGL product. Unlabelled AA (d 0 -AA, 1μM) serves as the internal standard. d 8 -AA and d 0 -AA are extracted from the aqueous buffered incubation mixtures by ethyl acetate. Upon solvent evaporation the residue is reconstituted in the mobile phase prior to LC-MS/MS analysis or in anhydrous acetonitrile for GC-MS analysis. LC-MS/MS analysis is performed in the negative electrospray ionization mode by selected-reaction monitoring the mass transitions [M-H] - →[M-H - CO 2 ] - , i.e., m/z 311→m/z 267 for d 8 -AA and m/z 303→m/z 259 for d 0 -AA. Prior to GC-MS analysis d 8 -AA and d 0 -AA were converted to their pentafluorobenzyl (PFB) esters by means of PFB-Br. GC-MS analysis is performed in the electron-capture negative-ion chemical ionization mode by selected-ion monitoring the ions [M-PFB] - , i.e., m/z 311 for d 8 -AA and m/z 303 for d 0 -AA. The GC-MS and LC-MS/MS assays were cross-validated. Linear regression analysis between the concentration (range, 0-1μM) of d 8 -AA measured by LC-MS/MS (y) and that by GC-MS (x) revealed a straight line (r 2 =0.9848) with the regression equation y=0.003+0.898x, indicating a good agreement. In dog liver, we detected MAGL activity that was inhibitable by the MAGL inhibitor JZL-184. Exogenous eicosatetraynoic acid is suitable as internal standard for the quantitative determination

    Human urine samples obtained before and after active and passive exposure to marijuana were analyzed by immune kits (Roche, Amersham, and Syva) and gas chromatography/mass spectrometry (GC/MS). Seven of eight subjects were positive for the entire five-day test period with one immune kit. The latter correlated with GC/MS in 98% of the samples. Passive inhalation experiments under conditions likely to reflect realistic exposure resulted consistently in less than 10 ng/mL of cannabinoids. The 10-100-ng/mL cannabinoid concentration range essential for detection of occasional and moderate marijuana users is thus unaffected by realistic passive inhalation.

    Many people diagnosed with cancer will receive chemotherapy as a core component of their care. Recent changes in the delivery of cancer services mean that patients frequently receive care on an out-patient basis and are therefore often required to manage related side effects at home without direct support from oncology health professionals. The use of information and communications technology may be seen as a means of supporting patients receiving chemotherapy in the home care setting. This mixed methods study, reports on the perceptions of nurses (n=35) who participated in a randomised controlled trial of a mobile phone based, Advanced Symptom Management System (ASyMS), in the management of chemotherapy-related toxicity in patients with breast, lung and colorectal cancer. Nurses' perceptions of ASyMS were evaluated at the start and the end of the study. Overall, they could see the benefits of ASyMS in the remote monitoring of chemotherapy toxicity and its role in facilitating early intervention and subsequent management, demonstrating the potential utility of the system within clinical practice.

    A simple and sensitive liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) technique was developed and validated for the determination of sibutramine and its N-desmethyl metabolites (M1 and M2) in human plasma. After extraction with methyl t-butyl ether, chromatographic separation of analytes in human plasma was performed using a reverse-phase Luna C18 column with a mobile phase of acetonitrile-10 mm ammonium formate buffer (50:50, v/v) and quantified by ESI-MS/MS detection in positive ion mode. The flow rate of the mobile phase was 200 μL/min and the retention times of sibutramine, M1, M2 and internal standard (chlorpheniramine) were 1.5, 1.4, 1.3 and 0.9 min, respectively. The calibration curves were linear over the range 0.05-20 ng/mL, for sibutramine, M1 and M2. The lower limit of quantification was 0.05 ng/mL using 500 μL of human plasma. The mean accuracy and the precision in the intra- and inter-day validation for sibutramine, M1 and M2 were acceptable. This LC-MS/MS method showed improved sensitivity and a short run time for the quantification of sibutramine and its two active metabolites in plasma. The validated method was successfully applied to a pharmacokinetic study in human. Copyright © 2011 John Wiley & Sons, Ltd.

    Recently, amylolytic activity was detected in IgMs isolated from the sera of the patients with multiple sclerosis. All purified samples of IgM were electrophoretically homogenous and did not contain any co-purified a-amylase and a-glucosidase activities, in accordance with a set of criteria developed for abzymes. The amylolytic activity of abzymes was studied in the hydrolysis of p-nitrophenyl a-D-maltooligosaccharides with different degrees of polymerization from 1 to 8 by TLC and reverse-phase HPLC techniques. All IgM samples isolated from 54 patients with clinically definite multiple sclerosis demonstrated hydrolytic activity towards the above artificial substrates. The Michaelis constant values (Km) in the hydrolysis of p-nitrophenyl a-D-maltoheptaoside were in the range of 10 p-nitrophenyl or p-nitrophenyl a-D-glucosides, thus indicating the presence of an a-D-glucosidase activity. For a number of the investigated samples, specific amylolytic activity increased depending on the length of substrates (from p-nitrophenyl maltopentaoside to p-nitrophenyl maltohexaoside); for other IgMs, the opposite dependence was observed. All IgMs studied did not exhibit any other glycoside hydrolase activities toward p-nitrophenyl glycoside substrates. Abzyme fractions from different donors demonstrated catalytic heterogeneity in Michaelis-Menten parameters and different modes of action in the hydrolysis of p-nitrophenyl maltooligosaccharides. Enzymatic properties of the IgMs tested varied from human a-amylases. All investigated abzyme samples did not show transglycosylating ability.

    Cystathionine β-synthase (CBS) deficiency is usually confirmed by assaying the enzyme activity in cultured skin fibroblasts. We investigated whether CBS is present in human plasma and whether determination of its activity in plasma could be used for diagnostic purposes. We developed an assay to measure CBS activity in 20 μL of plasma using a stable isotope substrate - 2,3,3-(2)H serine. The activity was determined by measurement of the product of enzyme reaction, 3,3-(2)H-cystathionine, using LC-MS\\/MS. The median enzyme activity in control plasma samples was 404 nmol\\/h\\/L (range 66-1,066; n = 57). In pyridoxine nonresponsive CBS deficient patients, the median plasma activity was 0 nmol\\/ho\\/L (range 0-9; n = 26), while in pyridoxine responsive patients the median activity was 16 nmol\\/hour\\/L (range 0-358; n = 28); this overlapped with the enzyme activity from control subject. The presence of CBS in human plasma was confirmed by an in silico search of the proteome database, and was further evidenced by the activation of CBS by S-adenosyl-L-methionine and pyridoxal 5\\'-phosphate, and by configuration of the detected reaction product, 3,3-(2)H-cystathionine, which was in agreement with the previously observed CBS reaction mechanism. We hypothesize that the CBS enzyme in plasma originates from liver cells, as the plasma CBS activities in patients with elevated liver aminotransferase activities were more than 30-fold increased. In this study, we have demonstrated that CBS is present in human plasma and that its catalytic activity is detectable by LC-MS\\/MS. CBS assay in human plasma brings new possibilities in the diagnosis of pyridoxine nonresponsive CBS deficiency.

    Site-specific isomerization of uridines into pseudouridines in RNAs is catalyzed either by stand-alone enzymes or by box H/ACA ribonucleoprotein particles (sno/sRNPs). The archaeal box H/ACA sRNPs are five-component complexes that consist of a guide RNA and the aCBF5, aNOP10, L7Ae, and aGAR1 proteins. In this study, we performed pairwise incubations of individual constituents of archaeal box H/ACA sRNPs and analyzed their interactions by native MS to build a 2D-connectivity map of direct binders. We describe the use of native MS in combination with ion mobility-MS to monitor the in vitro assembly of the active H/ACA sRNP particle. Real-time native MS was used to monitor how box H/ACA particle functions in multiple-turnover conditions. Native MS also unambiguously revealed that a substrate RNA containing 5-fluorouridine (f(5) U) was hydrolyzed into 5-fluoro-6-hydroxy-pseudouridine (f(5) ho(6) Ψ). In terms of enzymatic mechanism, box H/ACA sRNP was shown to catalyze the pseudouridylation of a first RNA substrate, then to release the RNA product (S22 f(5) ho(6) ψ) from the RNP enzyme and reload a new substrate RNA molecule. Altogether, our native MS-based approaches provide relevant new information about the potential assembly process and catalytic mechanism of box H/ACA RNPs. © 2015 WILEY-VCH Verlag GmbH & Co.

    The purpose of this study was to examine the current status of home care nursing services provided by community health nurses and to identify barriers to the services. A cross-sectional survey was conducted with three types of community health care nurses. Participants were 257 nurses, 46 of whom were hospital based home care nurses, 176 were community based visiting nurses, and 35 were long term care insurance based visiting nurses. A structured questionnaire on 7 domains of home care nursing services with a 4-point Likert scale was used to measure activities and barriers to care. Data were analyzed using SPSS WIN 21.0 program. Hospital based home care nurses showed a high level of service performance activity in the domain of clinical laboratory tests, medications and injections, therapeutic nursing, and education. Community based visiting nurses had a high level of service performance in the reference domain. Long term care insurance based visiting nurses showed a high level of performance in the service domains of fundamental nursing and counseling. The results show that although health care service provided by the three types of community health nurse overlapped, the focus of the service is differentiated. Therefore, these results suggest that existing home care services will need to be utilized efficiently in the development of a new nursing care service for patients living in the community after hospital discharge.

    To evaluate the effect of an active learning program on competency of senior students. Active learning strategies have been used to help students achieve desired nursing competency, but their effectiveness has not been systematically examined. A descriptive, cross-sectional comparative design was used. Two cohort group comparisons using t-test were made: one in an active learning group and the other in a traditional learning group. A total of 147 senior nursing students near graduation participated in this study: 73 in 2010 and 74 in 2013. The active learning program incorporated high-fidelity simulation, situation-based case studies, standardized patients, audio-video playback, reflective activities and technology such as a SmartPad-based program. The overall scores of the nursing competency in the active group were significantly higher than those in the traditional group. Of five overall subdomains, the scores of the special and general clinical performance competency, critical thinking and human understanding were significantly higher in the active group than in the traditional group. Importance-performance analysis showed that all five subdomains of the active group clustered in the high importance and high performance quadrant, indicating significantly better achievements. In contrast, the students in the traditional group showed scattered patterns in three quadrants, excluding the low importance and low performance quadrants. This pattern indicates that the traditional learning method did not yield the high performance in most important areas. The findings of this study suggest that an active learning strategy is useful for helping undergraduate students to gain competency. © 2014 John Wiley & Sons Ltd.

    This study was aimed (1) to compare the level of physical activity (PA) between working and nonworking hours and (2) to compare the level of PA during working hours of nurse clinical practitioners (NCPs) with that of nurse managers (NMs). This cross-sectional survey was conducted at a Thai university hospital from October 2015 to March 2016. All randomly selected participants wore an activity tracker on their hip for 5 days, except during bathing and sleeping periods, to record step counts and time points. Of 884 nurses, 289 (142 NCPs and 147 NMs) were randomly selected. The average age was 35.87 years. They spent 9.76 and 6.01 hours on work and nonwork activities, respectively. Daily steps per hour were significantly lower during work than nonwork periods (P work period of NCP was significantly higher than that of NM even after adjusting for age, work experience, and body mass index (P = .034). NCP had higher overall PA than NM, which was partly contributed by work-related PA. Level of PA for a professional with variation of actual work hours should be measured on hourly basis.

    Full Text Available Objectives: To identify the administrative and nursing care activities most performed by nurses in clinical/surgical units and to determine which are most and least pleasant to them. Methods: A descriptive-exploratory field study, with a quantitative approach and with a sample made up of 40 nurses working in clinical/surgical units who answered a three-part questionnaire composed of identification data and characterization of the professional; a list of nursing and administrative activities for the nurse to grade according to the numbers: “0 = I do not perform it”, “1 = I perform it occasionally”, “2 = I perform it often”, “3 = I perform it daily”; two open-ended questions, in which the nurse listed the activities he/she enjoyed the most and the least. Results: The administrative activities most performed by the nurses were: changing work shifts, preparing employee daily task charts and managing tests; the most performed nursing care activities were related to the stages of the Nursing Care Systematization and the interaction with the multi-professional team; the most enjoyable activities were direct patient care, patient evaluation and implementation of the systematization; the least enjoyable activities were administrative and bureaucratic routines, justification of complaints/problem-solving and preparation of employee task charts. Conclusion: Compared to administrative activities, nursing activities were performed most during the daily routine of the nurse, and the most enjoyable activities were those related to patient care, according to the opinions of the professionals.

    There is a wealth of international evidence concerning the contribution post-registration master's level education makes to advancing the discipline of nursing. There are approximately 277 nurse practitioners registered in NZ, but they account for only a small portion of nurses who have undertaken master's level education. The additional contribution these nurses make to the work environment through advanced practice activities has not, hitherto, been documented. To report the extent of advanced practice nurse activity associated with various levels of nursing education in a sample of nurses working in clinical practice in New Zealand. A replication of recent Australian research was done via a national cross-sectional survey of 3255 registered nurses and nurse practitioners in New Zealand using an online questionnaire to collect responses to the amended Advanced Practice Delineation survey tool. In addition, demographic data were collected including position titles and levels of postgraduate education. A positive association was found between postgraduate education at any level and more time spent in advanced practice activities. Independent of level of postgraduate education, the role a nurse holds also effects the extent of involvement in advanced practice activities. There is an additional contribution made to the work environment by nurses with master's level education which occurs even when they are not employed in an advanced practice role. These findings are of significance to workforce policy and planning across the globe as countries work to sustain health services by increasing nursing capacity effectively within available resources. © 2018 International Council of Nurses.

    The repair of DNA mediated by O(6)-alkylguanine-DNA alkyltransferase (AGT) provides protection against DNA damage from endogenous or exogenous alkylation of the O(6) position of guanine. However, this repair acts as a double-edged sword in cancer treatment, as it not only protects normal cells from chemotherapy-associated toxicities, but also results in cancer cell resistance to guanine O(6)-alkylating antitumour agents. Thus, AGT plays an important role in predicting the individual susceptibility to guanine O(6)-alkylating carcinogens and chemotherapies. Accordingly, it is necessary to establish a quantitative method for determining AGT activity with high accuracy, sensitivity and practicality. Here, we describe a novel nonradioactive method for measuring AGT activity using stable isotope dilution high-performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). This method is based on the irreversibility of the removal of the O(6)-alkyl group from guanine by AGT and on the high affinity of O(6)-benzylguanine (O(6)-BG) as an AGT substrate. HPLC-ESI-MS/MS was used to measure the AGT activities in cell protein extracts from eight tumour lines, demonstrating that AGT activity was quite variable among different cell lines, ranging from nondetectable to 1021 fmol/mg protein. The experiments performed in intact tumour cells yielded similar results but exhibited slightly higher activities than those observed in cell protein extracts. The accuracy of this method was confirmed by an examination of AGT expression levels using western blotting analysis. To our knowledge, this method is the first mass spectrometry-based AGT activity assay, and will likely provide assistance in the screening of cancer risk or the application of chemotherapies.

    Validating workload scores ensures that they are appropriate for the purpose for which they were developed. To validate the Nursing Activities Score (NAS) Spanish version. Observational and prospective study. 1,045 patients who were admitted to a medical-surgical unit and a serious burns unit in 2006 were included. The nurse in charge assessed patient workloads by Nine Equivalent of Nursing Manpower use Score and NAS. To assess the internal consistency of the measurements of NAS, item-test correlations, Cronbach's α and Cronbach's α corrected by omitting each of the items were calculated. The intraobserver and interobserver reliability were assessed with the intraclass correlation coefficient by viewing recordings and Kappa (interobserver reliability) was estimated. For the analysis of internal validity, a factorial principal components analysis was performed. Convergent validity was assessed using the Spearman correlation coefficient values obtained from the Nine Equivalent of Nursing Manpower use Score and Spanish-NAS scales. For internal consistency, 164 questionnaires were analysed and a Cronbach's α of 0.373 was calculated. The intraclass correlation coefficient for intraobserver reliability estimate was 0.837 (95% IC: 0.466-0.950) and 0.662 (95% IC: 0.033-0.882) for interobserver reliability. The estimated kappa was 0.371. For internal validity, exploratory factor analysis showed that the first item explained 58.9% of the variance of the questionnaire. For convergent validity 1006 questionnaires were included and a Spearman correlation coefficient of 0.746 was observed. The psychometric properties of Spanish-NAS are acceptable.

    Amorfrutins with a 2-hydroxybenzoic acid core structure are promising natural PPARγ agonists with potent antidiabetic activity. Owing to the complex matrix and low concentration in botanical material, the identification of unknown amorfrutins remains a challenge. In the present study, a combined application of UPLC-Q-TOF-MS and UPLC-QqQ-MS was developed to discover unknown amorfrutins from fruits of Amorpha fruticosa. First, reference compounds of amorfrutin A (AA), amorfrutin B (AB), and 2-carboxy-3,5-dihydroxy-4-geranylbibenzyl (AC) were analyzed using UPLC-Q-TOF-MS to reveal the characteristic fragment ions and the possible neutral loss. Second, the extract of A. fruticosa was separated and screened by UPLC-QqQ-MS using neutral loss scan to find out suspect compounds associated with the specified neutral fragment Δm/z 44. Third, the extract was re-analyzed by UPLC-Q-TOF-MS to obtain the exact mass of quasi-molecular ion and fragment ions of each suspect compound, and to subsequently calculate their corresponding molecular formulas. Finally, according to the molecular formula of suspect compound and its fragment ions and comparing with literature data, structure elucidation of four unidentified amorfrutins was achieved. The results indicated that the combination of QqQ-MS neutral loss scan and Q-TOF-MS molecular formula calculation was proven to be a powerful tool for unknown natural product identification, and this strategy provides an effective solution to discover natural products or metabolites of trace content.

    In recent years biologically active compounds isolated from insects call special interest of drug researchers. According to some Polish etnopharmacological observations, secretion from the grasshopper's abdomen (Orthoptera family) is believed to speed up the process of wound healing. In the present work we focused on determination of main components of the lipid fraction of material from grasshopper abdomen using GC-MS/MS. Samples were qualitatively analyzed using gas chromatography coupled with mass spectrometry. Both liquid-liquid extraction and solid-phase extraction pretreatment methods were used to concentrate and fractionate the compounds from the insect. In the derivatized fractions ca. 350 compounds were identified, including substances of known biological activity. The potential agents affecting wound healing have been indicated. A set of compounds characteristic for all the studied Chorthippus spp., have been identified. Data analysis revealed different lipidomic profiles of grasshoppers depending on the insects origin and collection area. Copyright © 2013 Elsevier B.V. All rights reserved.

    The structure of a polymeric proanthocyanidin fraction isolated from pear juice was characterized by NMR, ESI/MS, and MALDI-TOF/MS analyses, and its antioxidant activity was investigated using the DPPH free radical scavenging method. The results obtained from 13C NMR analysis showed the predominance of signals representative of procyanidins. Typical signals in the chemical shift region between 70 and 90 ppm demonstrated the exclusive presence of epicatechin units. The results obtained through negative ESI/MS analysis showed singly and doubly charged ions corresponding to the molecular mass of procyanidins with a degree of polymerization up to 22. The spectra obtained through MALDI-TOF/MS analysis revealed the presence of two series of tannin oligomers. Supporting the observations from NMR spectroscopy, the first series consists of well-resolved tannin identified as procyanidin polymers units with chain lengths of up to 25. A second series of monogalloyl flavan-3-ols polymers with polymerization degree up to 25 were also detected. This is the first mass spectrometric evidence confirming the existence of galloylated procyanidin oligomers in pear fruits. Within each of these oligomers, various signals exist suggesting the presence of several oligomeric tannins. The antioxidant properties of the polymeric fraction were investigated through reduction of the DPPH free radical, and the results obtained showed that the polymeric fraction exhibited a higher antioxidant power compared to those of (+)-catechin and B3 procyanidin dimer.

    A sensitive Liquid Chromatography tandem mass spectrometry (LC-MS/MS) method was developed and validated for the quantitative analysis of three potential genotoxic impurities (318BP, M9, S5) in meropenem Active Pharmaceutical Ingredient (API). Due to the requirement for LOD values in ppb range, a high concentration of meropenem API (30mg/mL) had to be injected. Therefore, efficient determination of meropenem from its impurities became a critical aim of this study, in order to divert meropenem to waste, via a switching valve. ‎ After the selection of the important factors affecting analytes' elution, a Box-Behnken design was utilized to set the plan of experiments conducted with UV detector. As responses, the separation factor s between the last eluting impurity and meropenem, as well as meropenem retention factor k were used. Grid point search methodology was implemented aiming to obtain the optimal conditions that simultaneously comply to the conflicted criteria. Optimal mobile phase consisted of ACN, methanol and 0.09% HCOOH at a ratio 71/3.5/15.5v/v. All impurities and internal standard omeprazole were eluted before 7.5min and at 8.0min the eluents were directed to waste. The protocol was transferred to LC-MS/MS and validated according to ICH guidelines. Copyright © 2017 Elsevier B.V. All rights reserved.

    The reducing tetrasaccharide TMG-chitotriomycin (1) is an inhibitor of β-N-acetylglucosaminidase (GlcNAcase), produced by the actinomycete Streptomyces anulatus NBRC13369. The inhibitor shows a unique inhibitory spectrum, that is, selectivity toward enzymes from chitin-containing organisms such as insects and fungi. Nevertheless, its structure-selectivity relationship remains to be clarified. In this study, we conducted a structure-guided search of analogues of 1 in order to obtain diverse N,N,N-trimethylglucosaminium (TMG)-containing chitooligosaccharides. In this approach, the specific fragmentation profile of 1 on ESI-MS/MS analysis was used for the selective detection of desired compounds. As a result, two new analogues, named TMG-chitomonomycin (3) and TMG-chitobiomycin (2), were obtained from a culture filtrate of 1-producing Streptomyces. Their enzyme-inhibiting activity revealed that the potency and selectivity depended on the degree of polymerization of the reducing end GlcNAc units. Furthermore, a computational modeling study inspired the inhibitory mechanism of TMG-related compounds as a mimic of the substrate in the Michaelis complex of the GH20 enzyme. This study is an example of the successful application of a MS/MS experiment for structure-guided isolation of natural products.

    Greer, Michael S; Zhou, Ting; Weselake, Randall J

    2014-08-01

    Diacylglycerol acyltransferase (DGAT) catalyzes the final step in the acyl-CoA-dependent biosynthesis of triacylglycerol (TAG), a high-energy compound composed of three fatty acids esterified to a glycerol backbone. In vitro DGAT assays, which are usually conducted with radiolabeled substrate using microsomal fractions, have been useful in identifying compounds and genetic modifications that affect DGAT activity. Here, we describe a high-temperature gas chromatography (GC)/mass spectrometry (MS)-based method for monitoring molecular species of TAG produced by the catalytic action of microsomal DGAT. This method circumvents the need for radiolabeled or modified substrates, and only requires a simple lipid extraction prior to GC. The utility of the method is demonstrated using a recombinant type-1 Brassica napus DGAT produced in a strain of Saccharomyces cerevisae that is deficient in TAG synthesis. The GC/MS-based assay of DGAT activity was strongly correlated with the typical in vitro assay of the enzyme using [1-(14)C] acyl-CoA as an acyl donor. In addition to determining DGAT activity, the method is also useful for determining substrate specificity and selectivity properties of the enzyme.

  12. Nurse Activism in the newborn intensive care unit: actions in response to an ethical dilemma.

    Settle, Peggy Doyle

    2014-03-01

    Nurses working in a newborn intensive care unit report that treatment decision disagreements for infants in their care may lead to ethical dilemmas involving all health-care providers. Applying Rest's Four-Component Model of Moral Action as the theoretical framework, this study examined the responses of 224 newborn intensive care unit nurses to the Nurses Ethical Involvement Survey. The three most frequent actions selected were as follows: talking with other nurses, talking with doctors, and requesting a team meeting. The multiple regression analysis indicates that newborn intensive care unit nurses with greater concern for the ethical aspects of clinical practice (p = .001) and an increased perception of their ability to influence ethical decision making (p = .018) were more likely to display Nurse Activism. Future research is necessary to identify other factors leading to and inhibiting Nurse Activism as these findings explained just 8.5% of the variance.

    Effective interpersonal skills are essential for head nurses in governing and managing their work units. Therefore, an active learning strategy could be the key to enhance the interpersonal competences of head nurses. This study aimed to investigate the effects of Peplau's theoretical approach of active learning on the improvement of head nurses' interpersonal skills. This study used a pre-experimental design with one group having pretests and posttests, without control group. A total sample of 25 head nurses from inpatient units of a wellknown private hospital in Jakarta was involved in the study. Data were analyzed using the paired t-test. The results showed a significant increase in head nurses' knowledge following the training to strengthen their interpersonal roles (P=.003). The results also revealed significant increases in the head nurses' skills in playing the roles of leader (P=.006), guardian (P=.014), and teacher/speaker (P=.015). Nonetheless, the results showed no significant increases in the head nurses' skills in playing the roles of counselor (P=.092) and stranger (P=.182). Training in strengthening the interpersonal roles of head nurses significantly increased the head nurses' knowledge and skills. The results of the study suggested the continuation of active learning strategies to improve the interpersonal abilities of head nurses. Furthermore, these strategies could be used to build the abilities of head nurses in other managerial fields. Copyright © 2018 Elsevier España, S.L.U. All rights reserved.

    2009-01-01

    This article describes findings from a qualitative policy study focused on female nurses' activism in relation to lesbian health. Critical feminist analysis and comparative life history methodology were applied to career histories obtained from 10 diversely situated female nurses across Ontario, Canada. The findings show that nursing activist practices are informed by advocacy experiences that foster inclusive professional and community education plus formal education processes that shape their political socialization. Implications for nursing theory include the development of political knowledges and practices that support caring science, sociopolitical knowing, and primary healthcare nursing practice in a community context.

    In Italy, the National Health System (SSN) grants healthcare to the citizens; its realization is up to the Government, the Regions and local institutions, with the participation of citizens. The Health Ministry determines the essential levels of care, and dictates the general guidelines for the activities of the SSN. On the whole national territory, a network of Local Healthcare Units (ASL) is present; such institutions, although belonging to the SSN, have local autonomy. Their activity is based upon principles of efficacy and efficiency; each one includes one or more Districts, which usually group a minimum of 60,000 citizens. Until 1999, Italian nurses have based their activity on a law that enumerated their tasks (DPR 225/74); nowadays, they work according to the indications of a professional profile (DM 739/94), a code of deontology, a law (L. 42/99) that has eliminated the old DPR, and university programmes. Apart from nurses, both in public and private healthcare facilities it is possible to find aids called OSS; their education consists of a twelve months programme, for which the regional institutions are responsible. Specific laws define their field of activity. For all these reasons, and also because of a major nursing shortage, in Italy it is not possible to talk about tasks delegations from doctors to nurses; we can, however, think about this process from nurses to aids and employees. Italy has the highest number of doctors in the world, with more than 6 every 1000 citizens in 2005 (approximately 370,000 units); nurses suffer from the opposite problem; nurses were 348,415 in 2005 and 360,874 in 2007, that is to say 5.4 nurses each 1000 citizens. This means a shortage of 60,000 nurses. Our research is aimed at: Studying the activities deployed by nurses in outpatients' facilities, that could be assigned to aids,; Identifying the tasks currently deployed by nurses, that are beyond their competence; Estimating how much time nurses could save, if they were

A sensitive and reliable high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) assay was developed and validated to enable reliable quantification of four diastereomeric and chemically reactive thiol metabolites, two of which are pharmacologically active, in human plasma. The metabolites were stabilized by alkylation of their reactive thiol moieties with 2-bromo-3'-methoxyacetophenone (MPB). Following organic solvent mediated-protein precipitation in a 96-well plate format, chromatographic separation was achieved by gradient elution on an Ascentis Express RP-amide column. Chromatographic conditions were optimized to ensure separation of the four derivatized active metabolites. Derivatized metabolites and stable isotope-labeled internal standards were detected by positive ion electrospray tandem mass spectrometry. The HPLC-MS/MS assay was validated over concentration ranges of 0.125-125 ng/mL for metabolites H1-H3 and 0.101-101 ng/mL for H4. Intra- and inter-assay precision values for replicate quality control samples were within 14.3% for all analytes during the assay validation. Mean quality control accuracy values were within ±6.3% of nominal values for all analytes. Assay recoveries were high (>79%). The four derivatized analytes were stable in human blood for at least 2 h at room temperature and on ice. The analytes were also stable in human plasma for at least 25 h at room temperature, 372 days at -20 °C and -70 °C, and following at least five freeze-thaw cycles. The validated assay was successfully applied to the quantification of all four thiol metabolites in human plasma in support of a human pharmacokinetic study. Copyright © 2013 Elsevier B.V.

    Two batches of the oenological tannin Tan'Activ R, (toasted oak wood - Quercus robur), were extracted with ethanol. A fractionation on XAD-16 afforded four fractions for each extract. Extracts and fractions were evaluated for antioxidant activity (DPPH), polyphenol content (GAE) and yeast α-glucosidase inhibitory activity. Comparable results were obtained for both columns, fractions X1B and X2B showing the highest antioxidant activity. Fractions X1C and X2C notably inhibited α-glucosidase, with IC50=9.89 and 8.05μg/mL, respectively. Fractions were subjected to HPLC/ESI-MS/MS and (1)H NMR analysis. The main phenolic constituents of both X1B and X2B were a monogalloylglucose isomer (1), a HHDP-glucose isomer (2), castalin (3) gallic acid (4), vescalagin (5), and grandinin (or its isomer roburin E, 6). X1C and X2C showed a complex composition, including non-phenolic constituents. Fractionation of X2C gave a subfraction, with enhanced α-glucosidase inhibitory activity (IC50=6.15μg/mL), with castalagin (7) as the main constituent. Copyright © 2016 Elsevier Ltd.

    We evaluated the association between the county sprawl index, a measure of residential density and street accessibility, and physical activity and body mass index (BMI). We conducted a multilevel cross-sectional analysis in a sample of Nurses' Health Study participants living throughout the United States in 2000 to 2001 (n = 136 592). In analyses adjusted for age, smoking status, race, and husband's education, a 1-SD (25.7) increase in the county sprawl index (indicating a denser, more compact county) was associated with a 0.13 kilograms per meters squared (95% confidence interval [CI] = -0.18, -0.07) lower BMI and 0.41 (95% CI = 0.17, 0.65) more metabolic equivalent (MET) hours per week of total physical activity, 0.26 (95% CI = 0.19, 0.33) more MET hours per week of walking, and 0.47 (95% CI = 0.34, 0.59) more MET hours per week of walking, bicycling, jogging, and running. We detected potential effect modification for age, previous disease status, husband's education level (a proxy for socioeconomic status), and race. Our results suggest that living in a dense, compact county may be conducive to higher levels of physical activity and lower BMI in women.

    A prodrug treosulfan (TREO) is currently investigated in clinical trials for conditioning prior to hematopoietic stem cell transplantation. Bioanalysis of TREO and its active derivatives, monoepoxide (S,S-EBDM) and diepoxide, in plasma and urine underlay the pharmacokinetic studies of these compounds but cannot explain an organ pharmacological action or toxicity. Recently, distribution of TREO and S,S-EBDM into brain, cerebrospinal fluid, and aqueous humor of the eye has been investigated in animal models and the obtained results presented clinical relevance. In this paper, a selective and rapid HPLC-ESI-MS/MS method was elaborated and validated for the studies of disposition of TREO and S,S-EBDM in rat plasma, liver, lungs, kidneys, muscle, and brain. The two analytes and codeine, internal standard (IS), were isolated from 50μL of plasma and 100μL of supernatants of the tissues homogenates using ultrafiltration Amicon vials. Chromatographic resolution was accomplished on C18 column with isocratic elution. The limits of quantitation of TREO and S,S-EBDM in the studied matrices ranged from 0.11 to 0.93μM. The HPLC-MS/MS method was adequately precise and accurate within and between runs. The IS-normalized matrix effect differed among the tissues and was the most pronounced in a liver homogenate supernatant (approximately 0.55 for TREO and 0.35 for S,S-EBDM). Stability of the analytes in experimental samples was also established. The validated method for the first time enabled determination of TREO and S,S-EBDM in the six life-important tissues in rats following administration of the prodrug. Copyright © 2017 Elsevier B.V.

    2018-03-01

    In flipped or blended classrooms, instruction intentionally shifts to a student-centered model for a problem-based learning approach, where class time explores topics in greater depth, creating meaningful learning opportunities. This article describes instructor-created activities focused on research processes linked to evidence-based practice that engage undergraduate nursing research students. In the classroom, these activities include individual and team work to foster critical thinking and stimulate student discussion of topic material. Six activities for small and large student groups are related to quantitative, qualitative, and both research processes, as well as applying research evidence to practice. Positive student outcomes included quantitative success on assignments and robust student topic discussions, along with instructor-noted overall group engagement and interest. Using these activities can result in class time for the construction of meaning, rather than primarily information transmission. Instructors may adopt these activities to involve and stimulate students' critical thinking about research and evidence-based practice. [J Nurs Educ. 2018;57(3):174-177.].

    Thousands of people treated in primary care are currently experiencing chronic pain (CP), for which management is often inadequate. In Quebec, nurses in family medicine groups (FMGs) play a key role in the management of chronic health problems. The present study aimed to describe the activities performed by FMG nurses in relation to CP management and to describe barriers to those activities. A descriptive correlational cross-sectional postal survey was used. The accessible population includes FMG nurses on the Ordre des infirmières et infirmiers du Québec list. All nurses on the list who provided consent to be contacted at home for research purposes were contacted. A self-administered postal questionnaire (Pain Management Activities Questionnaire) was completed by 53 FMG nurses. Three activities most often performed by nurses were to establish a therapeutic relationship with the client; discuss the effectiveness of therapeutic measures with the physician; and conduct personalized teaching for the patient. The average number of individuals seen by interviewed nurses that they believe suffer from CP was 2.68 per week. The lack of knowledge of possible interventions in pain management (71.7%) and the nonavailability of information on pain management (52.8%) are the main barriers perceived by FMG nurses. FMG nurses are currently performing few activities in CP management. The nonrecognition of CP may explain this situation.

    To assess what percentage of oncology nurses perceived themselves as having insufficient knowledge to provide advice on nutrition and/or physical activity (PA), which characteristics were associated with nurses' perception, and whether the content and information sources differed among those nurses.
. A cross-sectional study.
. A web-based survey among oncology nurses in the Netherlands.
. 355 oncology nurses provided advice on nutrition; of these, 327 provided advice on PA.
. From May to July 2013, oncology nurses were invited to complete an online questionnaire. Pearson's chi-squared tests and uni- and multivariate logistic regression analyses were conducted.
. Oncology nurses' perception of having sufficient or insufficient knowledge to be able to provide advice on nutrition and PA, the content of the advice, and the information sources on which the advice was based.
. 43% of oncology nurses perceived themselves as having insufficient knowledge to provide advice on nutrition, and 46% perceived insufficient knowledge to provide advice on PA. Factors associated with perceiving insufficient knowledge on nutrition were being aged younger, having lower education, and providing counseling during treatment only. Those nurses were more likely to suggest taking oral nutritional supplements or visiting a dietitian and were less likely to provide information on fluid intake. Nurses perceiving insufficient knowledge about PA used oncology guidelines less often.
. Almost half of the oncology nurses providing advice on nutrition and PA perceived themselves as having insufficient knowledge to be able to provide such advice. In particular, younger oncology nurses and oncology nurses with an intermediate vocational education may benefit most from education about these topics. 
. Educational training for oncology nurses should include nutrition and PA. Oncology nurses should collaborate with dietitians to discuss what information should be provided to patients by

    Full Text Available Oldenlandia diffusa has been used to treat various cancers. Cytochrome P450, a drug metabolic enzyme, might be influenced by herbal medicine. Currently, the problem that remains is the effective treatment in drug-drug interaction situation. Potential influences of Oldenlandia diffusa were elucidated on the CYP450 activities in rats using a cocktail method. Blood samples were precipitated by acetonitrile. Quantitative determination of target test object was done by ultra-performance liquid chromatography tandem mass spectrometry detection. Influences of oldenlandia diffusa on the activities of five CYP450 subtypes in rats were evaluated by five specific probe drugs (phenacetin for CYP1A2, omeprazole for CYP2C19, tolbutamide for CYP2C9, metoprolol for CYP2D6, and midazolam for CYP3A4 according to the pharmacokinetic parameters changes. No statistically significant difference (P>0.05 in pharmacokinetic behaviors can be observed in the five probe drugs. There is a potential guidance on clinical drug combination with Oldenlandia diffusa. Oldenlandia diffusa in compound preparation showed well security.

    2013-12-01

    Full Text Available The marine sponge Ectyoplasia ferox produces antipredatory and allelopathic triterpenoid glycosides as part of its chemical defense repertoire against predators, competitors, and fouling organisms. These molecules are responsible for the pharmacological potential found in the glycosides present in this species. In order to observe the glycochemical diversity present in E. ferox, a liquid chromatography coupled to a tandem mass spectrometry approach to analyse a complex polar fraction of this marine sponge was performed. This gave valuable information for about twenty-five compounds three of which have been previously reported and another three which were found to be composed of known aglycones. Furthermore, a group of four urabosides, sharing two uncommon substitutions with carboxyl groups at C-4 on the terpenoid core, were identified by a characteristic fragmentation pattern. The oxidized aglycones present in this group of saponins can promote instability, making the purification process difficult. Cytotoxicity, cell cycle modulation, a cell cloning efficiency assay, as well as its hemolytic activity were evaluated. The cytotoxic activity was about IC50 40 µg/mL on Jurkat and CHO-k1 cell lines without exhibiting hemolysis. Discussion on this bioactivity suggests the scanning of other biological models would be worthwhile.

    Lepidium meyenii (Maca), originated from Peru, has been cultivated widely in China as a popular health care food. However, the chemical and effective studies of Maca were less in-depth, which restricted its application seriously. To ensure the quality of Maca, a feasible and accurate strategy was established. One hundred and sixty compounds including 30 reference standards were identified in 6 fractions of methanol extract of Maca by UHPLC-ESI-Orbitrap MS. Among them, 15 representative active compounds were simultaneously determined in 17 samples by UHPLC-ESI-QqQ MS. The results suggested that Maca from Yunnan province was the potential substitute for the one from Peru. Meanwhile, the neuroprotective effects of Maca were investigated. Three fractions and two pure compounds showed strong activities in the 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP)-induced zebrafish model. Among them, 80% methanol elution fraction (Fr5) showed significant neuroprotective activity, followed by 100% part (Fr6). The inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) was a possible mechanism of its neuroprotective effect.

    Full Text Available Tabernaemontana catharinensis (Apocynaceae has been popularly used by folk medicine because of its anti-inflammatory, analgesic, and antiophidic properties. This study aims to analyze the flavonoids composition of the hydroethanolic extract and of the ethyl acetate (EtOAc and butanol (BuOH fractions of T. catharinensis leaves, as well as to evaluate their anti-inflammatory activity using in vivo models. The phytochemical profile, determined by High-Performance Liquid Chromatography–High-Resolution Electrospray Ionization-Mass Spectrometry (HPLC–HRESI-MS, showed the presence of flavonoids mainly having an isorhamnetin nucleus. The anti-inflammatory activity was evaluated in carrageenan-induced paw edema (pre- and post-treatment with oral administration of a T. catharinensis hydroethanolic extract (50, 100, and 150 mg/kg and of organic fractions (50 mg/kg. The extract and fractions showed antiedematogenic activity by decreasing myeloperoxidase (MPO production. In the zymosan-air-pouch model, the extract and fractions inhibited leukocyte migration and significantly decreased the levels of various proteins, such as MPO, interleukin (IL-1β, and tumor necrosis factor (TNF-α. The cytotoxicity was evaluated by the 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT assay, which revealed no cytotoxicity of the extract and the fractions. These results suggest that the hydroethanolic extract and organic fractions of T. catharinensis leaves have sufficient anti-inflammatory activity to support the popular use of this plant in the treatment of inflammatory disorders.

  12. Cultural Humility: An Active Concept to Drive Correctional Nursing Practice.

    Science.gov (United States)

    Steefel, Lorraine

    Correctional nursing practice is focused on a unique patient population: inmates who present with their own ethnicities and have an imposed culture from the prison structure. As such, culture must be considered to provide holistic care. Madeleine Leininger's Theory of Culture Care Diversity and Universality, which maintains that care is the essence of nursing (without inclusion of culture, there is no care), suggests three nursing actions: to maintain the patient's culture, make accommodations for it, and/or repattern cultural ways that may be unhealthful. Given that correctional nurses work within the context (and culture) of custody, Leininger's nursing actions may not always be feasible; however, showing an underlying attitude of cultural humility is. In this article, cultural humility, the basis of culturally competent care, is described in a manner that can drive nursing practice in corrections.

    2017-09-05

    We report the development of a rapid, simple, and robust LC-MS/MS-based enzyme assay using dried blood spots (DBS) for the diagnosis of pyridox(am)ine 5'-phosphate oxidase (PNPO) deficiency (OMIM 610090). PNPO deficiency leads to potentially fatal early infantile epileptic encephalopathy, severe developmental delay, and other features of neurological dysfunction. However, upon prompt treatment with high doses of vitamin B 6 , affected patients can have a normal developmental outcome. Prognosis of these patients is therefore reliant upon a rapid diagnosis. PNPO activity was quantified by measuring pyridoxal 5'-phosphate (PLP) concentrations in a DBS before and after a 30 min incubation with pyridoxine 5'-phosphate (PNP). Samples from 18 PNPO deficient patients (1 day-25 years), 13 children with other seizure disorders receiving B 6 supplementation (1 month-16 years), and 37 child hospital controls (5 days-15 years) were analyzed. DBS from the PNPO-deficient samples showed enzyme activity levels lower than all samples from these two other groups as well as seven adult controls; no false positives or negatives were identified. The method was fully validated and is suitable for translation into the clinical diagnostic arena.

    The aim of this study was to identify the contribution of Irish intellectual disability clinical nurse specialists (ID CNSs) to service delivery. A nonexperimental descriptive design was selected to survey ID CNSs presently working in Ireland. The questionnaire was developed based on focus group interviews, available literature, and expert panel views. Ethical approval and access were granted to all ID CNSs in Ireland. Thirty-two responded (33.68% response rate) from all work areas (voluntary organizations or health service executive) practicing within residential, community, or school services. Respondents were surveyed across a range of areas (demographic details and support to client, staff, family, organization, community, other agencies, and professional development). Findings identify that ID CNSs are active in all aspects of their roles as clinical specialist, educator, communicator, researcher, change agent, and leader, thus supporting person-centered care and improving service delivery. To meet changing healthcare demands, promote person-centered care, and improve service delivery, the CNS role in ID should be developed and supported. The findings merit a further study on ID CNS role activity, possible variables influencing role activity, and team members' views.

    The amount of time nurses spend providing direct patient care seems to be continually eroding. So it's little wonder a survey conducted last year of critical care, OR nurses and nurse executives found that half of the 1600 respondents feel they spend too much time on supply chain duties. Most also said their supply chain duties impact patient safe ty and their ability to provide bedside care. Experts interviewed for this report believe it's time for supply chain leaders and nurses to develop a closer working partnership. Included are their recommendations to improve performance.

    Over the past three decades, active euthanasia and abortion have received increasing international attention. Since both these practices are relevant to the role of the nurse-midwife, it is important to know what influences their attitudes towards them. Therefore, the purpose of this study was: 1, to survey the attitudes of nurse-midwives' to active euthanasia and its legalization; 2, to determine the relationship between nurse-midwives' attitudes toward active euthanasia and its legalization, and attitudes toward abortion, self-reported religiosity and religious affiliation. The study setting was an international midwifery conference and the sample consisted of 139 nurse-midwives attending the conference. The majority of nurse-midwives displayed a positive attitude toward active euthanasia and its legalization. In addition, there was a positive relationship between their attitude to abortion and active euthanasia. Self-reported religiosity and religious affiliation were significantly related to attitudes toward active euthanasia and its legalization. An interesting positive relationship between country of practice and attitudes to euthanasia was also found. Nurse-midwives practicing in countries with more liberal euthanasia and assisted suicide legislation were more supportive of active euthanasia. With the increasing acceptance of active euthanasia's legalization, the results of this study pose some ethical questions that nurse-midwives internationally will have to consider.

    2009-02-01

    There is a shortage of military Certified Registered Nurse Anesthetists (CRNAs). Relative deprivation is a perception of unfairness due to discrepancies between what one has and what one could or should have that is dependent on feelings (subjective data) and facts (objective data). Feelings of relative deprivation could contribute to the military CRNA shortage. The purposes of this study were to measure relative deprivation in active-duty military CRNAs and explore variables that correlate with relative deprivation. The descriptive, correlational study was conducted using a self-administered survey sent to 435 active-duty Army, Navy, and Air Force CRNAs. Surveys were distributed to subjects by mail and could be answered by mail or by secured website. Data were analyzed using descriptive and inferential statistics. Analysis of the data revealed a calculated response rate of 57.7%. There was no significant correlation (P pay, promotion opportunity, or scope of practice/autonomy and relative deprivation. Correlations of the psychological factors "wanting" and "deserving" with relative deprivation were significant (P < .001). Further research is indicated to identify definitive factors that can be modified to improve feelings of deprivation as they relate to retention and recruitment of military CRNAs.

    Teachers and staff members engaged in nursing activity experience more stress than other workers. However, it is unknown whether teachers engaged in nursing activity in schools for handicapped children experience even greater stress. This study evaluated job stressors and job stress among such teachers using a cross-sectional study design. The subjects were all 1,461 teachers from all 19 prefectural schools for handicapped children in Shizuoka Prefecture, Japan. We used a brief job stress questionnaire for the survey and 831 teachers completed the questionnaire. Job stressors among teachers engaged in nursing activity were compared with those among teachers not engaged in nursing activity. Job stress among such teachers was estimated by the score for total health risk, and was compared with the score in the Japanese general population. Male and female teachers engaged in nursing activity had a significantly higher level of job stressors for physical work load and job control compared with those not engaged in nursing activity. The scores for total health risk among male and female teachers engaged in nursing activity were 102 points and 98 points, respectively. These scores were not markedly above 100 points which is the mean score in the Japanese general population.

    Recent nursing research using a critical feminist lens challenges the prevailing view of political inertia in nursing. This comparative life history study using a critical feminist lens explores the relevance of activism with four generations of Canadian nurses. Purposeful sampling of Ontario nurses resulted in 40 participants who were diverse in terms of generation, practice setting, and activist practice. Interviews and focus groups were completed with the sample of Ontario registered nurses or undergraduate and graduate nursing students: 8 Generation X, 9 Generation Y (Millennials), 20 Boomers, and 3 Overboomers. Factors such as professional norms and personal and organizational supports shaped contradictory nursing activist identities, practices, and impacts. Gendered norms, organizational dynamics, and the political landscape influenced the meanings nurses attributed to critical incidents and influences that prompted activism inside and outside the workplace, shaping the transformative potential of nursing. Despite its limitations, the study has implications for creating professional and organizational supports for consideration of health politics and policy, and spaces for dialogue to support practice and research aligned with social justice goals.

    Medicinal plants are rich source of traditional herbal medicine around the globe. Most of the plant's therapeutic properties are due to the presence of secondary bioactive compounds. The present study analyzed the High Pressure Liquid Chromatography (HPLC) fractions of Puncia granatum (peel) extracts (aqueous, chloroform, ethanol and hexane) against multidrug resistant bacterial pathogens (Acinetobacter baumannii, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus). All the fractions having antibacterial activity was processed for bioactive compounds identification using LC MS/MS analysis. Among total HPLC fractions (n = 30), 4 HPLC fractions of P. granatum (peel) showed potential activity against MDR pathogens. Fraction 1 (F1) and fraction 4 (F4) collected from aqueous extract showed maximum activity against P. aeruginosa. Fraction 2 (F2) of hexane showed antibacterial activity against three pathogens, while ethanol F4 exhibited antibacterial activity against A. baumannii. The active fractions were processed for LC MS/MS analysis to identify bioactive compounds. Valoneic acid dilactone (aqueous F1 and F4), Hexoside (ethanol F4) and Coumaric acid (hexane F2) were identified as bioactive compounds in HPLC fractions. Puncia granatum peel extracts HPLC fractions exhibited potential inhibitory activity against MDR bacterial human pathogens. Several bioactive compounds were identified from the HPLC fractions. Further characterization of these compounds may be helpful to conclude it as therapeutic lead molecules against MDR pathogens.

    1. Pinoresinol di-O-β-d-glucopyranoside (PDG), geniposide (GE), geniposidic acid (GA), aucubin (AN) and chlorogenic acid (CA) are the representative active ingredients in Eucommiae cortex (EC), which may be estrogenic. 2. The ultra high-performance liquid chromatography/tandem mass spectrometry (UHPLC-MS/MS) method for simultaneous determination of the five ingredients showed good linearity, low limits of quantification and high extraction recoveries, as well as acceptable precision, accuracy and stability in mice plasma and tissue samples (liver, spleen, kidney and uterus). It was successfully applied to the comparative study on pharmacokinetics and tissue distribution of PDG, GE, GA, AN and CA between normal and ovariectomized (OVX) mice. 3. The results indicated that except CA, the plasma and tissue concentrations of PDG, GE, GA in OVX mice were all greater than those in normal mice. AN could only be detected in the plasma and liver homogenate of normal mice, which was poorly absorbed in OVX mice and low in other measured tissues. PDG, GE and GA seem to be better absorbed in OVX mice than in normal mice proved by the remarkable increased value of AUC0-∞ and Cmax. It is beneficial that PDG, GE, GA have better plasma absorption and tissue distribution in pathological state.

    The total phenolic content and radical scavenging activity of Andrographis paniculata has been investigated to estimate the amount of phenolic compounds and diterpene lactones, respectively in the plant extracts. The stem extracts exhibited higher total phenolic content and scavenging activity than those of the leaf extracts from both young and mature plants. A range of 19.6-47.8 mg extract of A. paniculata from different parts of the plant is equivalent to the scavenging activity exhibited by one mg of standard Trolox. HPLC-ESI-MS/MS was also used to identify simultaneously the phytochemicals from the leaves and stems of both young and mature plant samples. Of the identified compounds, seven of the sixteen diterpene lactones, three of the six flavonoids, five of the six phenolic acids and two cyclic acids are reported here for the first time for this species. Multivariate statistical approaches such as Hierarchiral Component Analysis (HCA) and Principle Component Analysis (PCA) have clustered the plant extracts into the leaf and stem groups, regardless of plant age. Further classification based on the phytochemical profiles revealed that mostly phenolic acids and flavonoids were from the young leaf extracts, and diterpenoids and their glycosides from the mature leaf extracts. However, the phytochemical profiles for the stems of both young and mature plants were not significantly different as presented in the dendrogram of HCA and the score plot of PCA. The marker for mature plants might be the m/z 557 ion (dihydroxyl dimethyl 19-[(beta-D-glucopyranosyl)oxy]-19-oxo-ent-labda-8(17),13-dien-16,15-olide), whereas the m/z 521 ion (propyl neoandrographolide) could be the marker for leaf extracts.

    Nursing faculty often struggle to find effective teaching strategies for nursing students that integrate group work into nursing students' learning activities. This study was conducted to evaluate students' experiences in a psychiatric and mental health nursing course using psychosocial group activities to develop therapeutic communication and interpersonal relationship skills, as well as to introduce psychosocial nursing interventions. A qualitative research design was used. The study explored nursing students' experiences of the course in accordance with the inductive, interpretative, and constructive approaches via focus group interviews. Participants were 17 undergraduate nursing students who registered for a psychiatric and mental health nursing course. The collected data were analyzed by qualitative content analysis. The analysis resulted in 28 codes, 14 interpretive codes, 4 themes (developing interpersonal relationships, learning problem-solving skills, practicing cooperation and altruism, and getting insight and healing), and a core theme (interdependent growth in self-confidence). The psychosocial group activity provided constructive opportunities for the students to work independently and interdependently as healthcare team members through reflective learning experiences.

    Efficacy assessments using a combination of ibrutinib and lenalidomide necessitate the development of an analytical method for determination of both drugs in plasma with precision. A high performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous determination of lenalidomide, ibrutinib, and its active metabolite PCI45227 in rat plasma. Extraction of lenalidomide, ibrutinib, PCI45227 and tolbutamide (internal standard; IS) from 50 μl rat plasma was carried out by liquid-liquid extraction with ethyl acetate:dichloromethane (90:10) ratio. Chromatographic separation of analytes was performed on YMC pack ODS AM (150 mm × 4.6 mm, 5 μm) column under gradient conditions with acetonitrile:0.1% formic acid buffer as the mobile phases at a flow rate of 1 ml/min. Precursor ion and product ion transition for analytes and IS were monitored on a triple quadrupole mass spectrometer, operated in the selective reaction monitoring with positive ionization mode. Method was validated over a concentration range of 0.72-183.20 ng/ml for ibrutinib, 0.76-194.33 ng/ml for PCI-45227 and 1.87-479.16 ng/ml for lenalidomide. Mean extraction recovery for ibrutinib, PCI-45227, lenalidomide and IS of 75.2%, 84.5%, 97.3% and 92.3% were consistent across low, medium, and high QC levels. Precision and accuracy at low, medium and high quality control levels were less than 15% across analytes. Bench top, wet, freeze-thaw and long term stability was evaluated for all the analytes. The analytical method was applied to support a pharmacokinetic study of simultaneous estimation of lenalidomide, ibrutinib, and its active metabolite PCI-45227 in Wistar rat. Assay reproducibility was demonstrated by re-analysis of 18 incurred samples. Copyright © 2014 Elsevier B.V. All rights reserved.

    To describe how registered nurse work motivation, attitudes, subjective norm and perceived behavioural control influence intention to promote physical activity in hospitalised adult liver transplant recipients. Descriptive study of clinical registered nurses caring for recipients of liver transplant at a tertiary medical centre. Intent to Mobilise Liver Transplant Recipient Scale, Work Extrinsic and Intrinsic Motivation Scale, and demographics were used to explore registered nurses' work motivation, attitudes, subjective norms, perceived behavioural control and intention to promote physical activity of hospitalised adult liver transplant recipients during the acute postoperative phase. Data analysis included demographics, comparison between scale items and analysis of factors predicting intent to mobilise. Factors predictive of intention to promote physical activity after liver transplant included appropriate knowledge to mobilise patients (R 2  = .40) and identification of physical activity as nursing staff priority (R 2  = .15) and responsibility (R 2  = .03). When implementing an early mobilisation protocol after the liver transplant, education on effects of physical activity in the immediate postoperative period are essential to promote implementation in practice. Nursing care environment and leadership must be supportive to ensure mobility is a registered nurse priority and responsibility. Nursing managers can leverage results to implement a mobility protocol. © 2017 John Wiley & Sons Ltd.

    Although physical activity may reduce disease burden, fatigue and disability, and improve quality of life among people with multiple sclerosis (MS), many people with MS are physically inactive and spend significant time in sedentary behaviour. Behaviour change interventions may assist people with MS to increase physical activity and reduce sedentary behaviour. However, few studies have investigated their effectiveness using objective measures of physical activity, particularly in the long term. Further, interventions that have proven effective in the short term may not be feasible in clinical practice because of the large amount of support provided. The iStep-MS trial aims to determine the safety, feasibility and acceptability of a behaviour change intervention to increase physical activity and reduce sedentary behaviour among people with MS. Sixty people with MS will be randomised (1:1 ratio) to receive a 12-week intervention or usual care only. The intervention consists of four physical activity consultations with a physiotherapist supported by a handbook and pedometer. Outcomes assessed at baseline, 12 weeks and 9 months are physical activity (ActiGraph wGT3X-BT accelerometer), sedentary behaviour (activPAL3µ), self-reported activity and sitting time, walking capability, fatigue, self-efficacy, participation, quality of life and health service use. The safety of the intervention will be determined by assessing change in pain and fatigue and the incidence of adverse events during the follow-up period. A parallel process evaluation will assess the feasibility and acceptability of the intervention through assessment of fidelity to the programme and semistructured interviews exploring participants' and therapists' experiences of the intervention. The feasibility of conducting an economic evaluation will be determined by collecting data on quality of life and resource use. Research ethics committee approval has been granted from Brunel University London. Results of

    The aim of this study was to examine whether there was a difference between clinical nurses who were research-active, and clinical nurses who were nonresearch-active in utilization of research. A further aim was to identify the most significant barriers faced by a group of Danish clinical nurses in their use of research. Discrepancy between the improved quality of research results and the lack of implementing them was the starting point for a series of studies which showed the types of barriers clinical nurses found especially cumbersome when applying the research results of other researchers. This study investigates whether the clinical nurses' own engagement in research had any impact on their perception of research utilization. The study had an exploratory and descriptive design. Seventy-nine Danish clinical nurses participated and semi-structured interviewing was used as the research method. There was a statistically significant difference between the research-active and nonresearch-active nurses on various variables. The study showed that, to a larger extent, research-active nurses used evidence-based knowledge and were generally more internationally orientated. Furthermore, two important barriers for research utilization were identified by all 79 clinical nurses included in the study, i.e. 90% of the nurses explained that the quantity of research results was overwhelming, and 75% of them found that they were unable to evaluate the quality of the research. Clinical nurses, who were research-active themselves, experienced more success in overcoming some of the barriers, which existed in applying research to practice. The research potential found amongst clinical nurses in Denmark needed to be further supported through training and guidance in research methodology, establishing introductory stipends and part-time research positions. By doing so, some of the barriers affecting research utilization and the so-called theory-practice gap might be reduced. Further

    A mutant MS301 of Aspergillus niger MS82 showed 1.5 to 2.5-fold improved endoglucanase and beta-glucosidase activity when grown on crude lignocellulosic substrates under solid-state and submerged conditions. Indicators of thermal stability of enzymes (Tm and T1/2) showed that the wild type and mutant endoglucanase was more heat-resistant compared to beta-glucosidase. However, mutant and parent enzymes shared almost the same values for melting temperatures and half-lives. Endoglucanase and beta-glucosidase from both the strains showed optimum activity under acidic pH. Energy of activation (Ea) of mutant beta-glucosidase was substantially lower than the parent enzyme while Ea of mutant endoglucanase was slightly less than the parent. The lowered Ea values can be attributed to the improved beta-glucosidase activity of the mutant strain. Moreover, the MS301 enzymes were better in hydrolyzing purified and crude cellulosic materials than the parent MS82. (author)

    We surveyed 2 cohorts of early-career registered nurses from 15 states in the US, 2 years apart, to compare their reported participation in hospital quality improvement (QI) activities. We anticipated differences between the 2 cohorts because of the growth of several initiatives for engaging nurses in QI. There were no differences between the 2 cohorts across 14 measured activities, except for their reported use of appropriate strategies to improve hand-washing compliance to reduce nosocomial infection rates.

    It has been described that the sensitivity of the Carba NP test may be low in the case of OXA-48-like carbapenamases and mass spectrometry based methods as well as a colorimetry based method have been described as alternatives. We evaluated 84 Enterobacteriaceae isolates including 31 OXA-48-like producing isolates and 13 isolates that produced either an imipenemase (IMP; n=8), New Delhi metallo-β-lactamase (NDM; n=3), or Klebsiella pneumoniae carbapenemase (KPC; n=2), as well as 40 carbapenemase negative Enterobacteriaceae isolates. We used the Neo-Rapid CARB kit, assessing the results with the unaided eye and compared it with a colorimetric approach. Furthermore, we incubated the isolates in growth media with meropenem and measured the remaining meropenem after one and 2h of incubation, respectively, using liquid chromatography tandem mass spectrometry (LC-MS/MS). Whilst all carbapenemase producing isolates with the exception of the OXA-244 producer tested positive for both the Neo-rapid CARB test using the unaided eye or colorimetry, and the 13 isolates producing either IMP, NDM or KPC hydrolysed the meropenem in the media almost completely after 2h of incubation, the 31 OXA-48-like producing isolates exhibited very variable hydrolytic activity when incubated in growth media with meropenem. In our study, the Neo-Rapid CARB test yielded a sensitivity of 98% for both the traditional and the colorimetric approach with a specificity of 95% and 100% respectively. Our results indicate that the Neo-Rapid CARB test may have use for the detection of OXA-48 type carbapenemases and that it may be particularly important to ensure bacterial lysis for the detection of these weaker hydrolysers.

    Fuzi Xiexin Tang (FXT) is a classic traditional Chinese medicine formula which has been employed in clinical for more than 1800 years. The distinctive preparation method (maceration) recorded in ancient time is different from one in modern clinical practice (decoction). Aim of this study is to investigate the pharmacokinetic difference of alkaloids, flavones and anthraquinones in rats after oral administration of decoction of FXT (DFXT, 30gkg(-1)), maceration of FXT (MFXT, 30gkg(-1)) and decoction of Aconiti Lateralis Radix Preparata (DAR, 6gkg(-1)) by a validated UPLC-MS/MS method. Plasma concentrations and pharmacokinetic parameters of 16 active constituents (aconitine, hypaconitine, mesaconitine, benzoylaconine, benzoylhypaconine, benzoylmesaconine, berberine, palmatine, jatrorrhizine, coptisine, baicalin, wogonin, wogonoside, emodin, aloe-emodin, rhein) in rat were quantified and compared. Different preparative methods resulted in significant difference on exposure and pharmacokinetic characteristics of alkaloids, flavones and anthraquinones from FXT, especially protoberberine alkaloids. Concentrations of monoester-diterpenoid alkaloids were below the LOD in rat plasma after administration of DFXT and MFXT because of the existence of other three herbs from FXT. Maceration could decrease the absorption of flavones while increased the absorption of anthraquinones. Cmax of emodin and rhein were 3.1 and 10.3 times increased, while eliminations of these two constituents were 8.0 and 19.0 times slower after administration of MFXT. Bioavailability of both flavones and anthraquinones increased after administration of MFXT, especially emodin and rhein increasing as much as 13.5 and 20.7 times. Herb-herb interaction between DAR and other three herbs from FXT significantly influenced the exposure of aconitum alkaloids. Copyright © 2014 Elsevier B.V. All rights reserved.

    A method was developed using automated headspace solid-phase microextraction coupled with GC/MS/MS to simultaneously determine the presence of seven biologically active flavoring substances whose levels of use in processed foods is controlled by statutory limits. The method can be applied to identify and quantify the presence of 1,2-benzopyrone (coumarin), beta-asarone, 1-allyl-4-methoxybenzene (estragole), menthofuran, 4-allyl-1 ,2-dimethoxybenzene (methyl eugenol), pulegone, and thujone at levels ranging from 0.5 to 3000 mg/kg. The method has been optimized and validated for three different generic food types categorized on the basis of composition and anticipated use levels of flavorings and food ingredients. The food categories are alcoholic and nonalcoholic beverages; semisolid processed foods (e.g., soups, sauces, confectionary, etc.); and solid foods (muesli, bakery products, etc.). The method is simple, inexpensive, and rapid, and eliminates the use of flammable and toxic solvents. There is no sample preparation, and using MSIMS, unequivocal confirmation of identification is achieved even in highly complex matrixes containing many potential interfering volatiles. The method precision for spiked samples ranged from 2 to 21%, with the greatest variability associated with solid matrixes. The LOD and LOQ values were well below 0.1 and 0.5 mg/kg, respectively, in all cases for individual substances, fulfilling requirements for enforcement purposes. The robustness of the method was demonstrated in a small survey of retail samples of four spirits, five flavored milks, three energy drinks, five liqueurs, five soups, 10 sauces, five herbal teas, and three breakfast cereals.

    Hospitals often promote healthy lifestyles, but little is known about nurses' actual diet and physical activity. Greater understanding about these lifestyle choices for clinical nurses may improve existing hospital-based programs and/or create desirable services. This article discusses a study that considered diet and physical activity of clinical nurses, using elements of Pender's self-care theory as a conceptual framework. Study methods included a cross-sectional, correlational design and a convenience sample of 278 nurses who worked on units with 24 hours/day and seven days-per-week responsibilities. Participants completed diet and exercise questionnaires about perceptions of attitudes and opinions, barriers, diet benefits/exercise motivators, self-efficacy, and locus of control, and personal and work characteristics. Diet and activity categories were created. Study results demonstrated that over 50% of nurses had moderately healthy diets but were insufficiently active. Healthy diet and physical activity levels were associated with higher self-efficacy, more diet benefits and physical activity motivators, fewer perceived barriers, and confidence in body image. The article discussion and conclusion sections note areas for future research and suggest that focused interventions that address benefits, motivators, and self-efficacy may increase participation in hospital-based programs and enhance healthy lifestyle for hospital-based clinical nurses.

    Clinical nurses need lifelong learning skills for responding to the rapid changes of clinical settings. One of the best strategies for lifelong learning is self-directed learning. The aim of this study was to explore Iranian clinical nurses' activities for self-directed learning. In this qualitative study, 23 semi-structured personal interviews were conducted with nineteen clinical nurses working in all four hospitals affiliated to Isfahan Social Security Organization, Isfahan, Iran. Study data were analyzed by using the content analysis approach. The study was conducted from June 2013 to October 2014. Study participants' activities for self-directed learning fell into two main categories of striving for knowledge acquisition and striving for skill development. The main theme of the study was 'Revising personal performance based on intellectual-experiential activities'. Study findings suggest that Iranian clinical nurses continually revise their personal performance by performing self-directed intellectual and experiential activities to acquire expertise. The process of acquiring expertise is a linear process which includes two key steps of knowledge acquisition and knowledge development. In order to acquire and advance their knowledge, nurses perform mental learning activities such as sensory perception, self-evaluation, and suspended judgment step-by-step. Moreover, they develop their skills through doing activities like apprenticeship, masterly performance, and self-regulation. The absolute prerequisite to expertise acquisition is that a nurse needs to follow these two steps in a sequential manner.

  7. Status of costing hospital nursing work within Australian casemix activity-based funding policy.

    Australia has a long history of patient level costing initiated when casemix funding was implemented in several states in the early 1990s. Australia includes, to some extent, hospital payment based on nursing intensity adopted within casemix funding policy and the Diagnostic Related Group system. Costing of hospital nursing services in Australia has not changed significantly in the last few decades despite widespread introduction of casemix funding policy at the state level. Recent Commonwealth of Australia National Health Reform presents change to the management of the delivery of health care including health-care costing. There is agreement for all Australian jurisdictions to progress to casemix-based activity funding. Within this context, nurse costing infrastructure presents contemporary issues and challenges. An assessment is made of the progress of costing nursing services within casemix funding models in Australian hospitals. Valid and reliable Australian-refined nursing service weights might overcome present cost deficiencies and limitations. © 2012 Blackwell Publishing Asia Pty Ltd.

  8. Caregiver Activation and Home Hospice Nurse Communication in Advanced Cancer Care.

    Activated patients have the skills, knowledge, and confidence to manage their care, resulting in positive outcomes such as lower hospital readmission and fewer adverse consequences due to poor communication with providers. Despite extensive evidence on patient activation, little is known about activation in the home hospice setting, when family caregivers assume more responsibility in care management. We examined caregiver and nurse communication behaviors associated with caregiver activation during home hospice visits of patients with advanced cancer using a prospective observational design. We adapted Street's Activation Verbal Coding tool to caregiver communication and used qualitative thematic analysis to develop codes for nurse communications that preceded and followed each activation statement in 60 audio-recorded home hospice visits. Caregiver communication that reflected activation included demonstrating knowledge regarding the patient/care, describing care strategies, expressing opinions regarding care, requesting explanations of care, expressing concern about the patient, and redirecting the conversation toward the patient. Nurses responded by providing education, reassessing the patient/care environment, validating communications, clarifying care issues, updating/revising care, and making recommendations for future care. Nurses prompted caregiver activation through focused care-specific questions, open-ended questions/statements, and personal questions. Few studies have investigated nurse/caregiver communication in home hospice, and, to our knowledge, no other studies focused on caregiver activation. The current study provides a foundation to develop a framework of caregiver activation through enhanced communication with nurses. Activated caregivers may facilitate patient-centered care through communication with nurses in home hospice, thus resulting in enhanced outcomes for patients with advanced cancer.

    Hospital nurses who are working mothers are challenged to maintain their personal health and model healthy behaviors for their children. This study aimed to develop and test an innovative 10-week worksite physical activity intervention integrated into the work flow of hospital-based nurses who were mothers. Three volunteer adult medical-surgical nursing units participated as intervention units. Fifty-eight nurses (30 intervention and 28 control) provided baseline and post-intervention repeated measurements of physical activity (steps) and body composition. Intervention participants provided post-intervention focus group feedback. For both groups, daily steps averaged more than 12,400 at baseline and post-intervention. No significant effects were found for physical activity; significant effects were found for fat mass, fat index, and percent fat (p working mothers. Future research is warranted with a larger sample, longer intervention, and additional measures. Copyright 2011, SLACK Incorporated.

    To investigate physical activity levels of nursing and medicine students, examine predictors of physical activity level and examine the most influential benefits and barriers to exercise. Healthcare professionals have low levels of physical activity, which increases their health risk and may influence their health promotion practices with patients. We surveyed 361 nursing (n = 193) and medicine (n = 168) students studying at a UK medical school. Questionnaire survey, active over 12 months in 2014-2015. Measures included physical activity level, benefits and barriers to exercise, social support, perceived stress and self-efficacy for exercise. Many nursing and medicine students did not achieve recommended levels of physical activity (nursing 48%; medicine 38%). Perceived benefits of exercise were health related, with medicine students identifying additional benefits for stress relief. Most notable barriers to exercise were as follows: lack of time, facilities having inconvenient schedules and exercise not fitting around study or placement schedules. Nursing students were less active than medicine students; they perceived fewer benefits and more barriers to exercise and reported lower social support for exercise. Physical activity of nursing and medicine students was best predicted by self-efficacy and social support, explaining 35% of the variance. Physical activity should be promoted in nursing and medicine students. Interventions should aim to build self-efficacy for exercise and increase social support. Interventions should be developed that are targeted specifically to shift-working frontline care staff, to reduce schedule-related barriers to exercise and to increase accessibility to workplace health and well-being initiatives. © 2016 John Wiley & Sons Ltd.

    Nurses play a key role in the prevention of cardiovascular disease (CVD) and one would, therefore, expect them to have a heightened awareness of the need for systematic screening and their own CVD risk profile. The aim of this study was to examine personal awareness of CVD risk among a cohort of cardiovascular nurses attending a European conference. Of the 340 delegates attending the 5th annual Spring Meeting on Cardiovascular Nursing (Basel, Switzerland, 2005), 287 (83%) completed a self-report questionnaire to assess their own risk factors for CVD. Delegates were also asked to give an estimation of their absolute total risk of experiencing a fatal CVD event in the next 10 years. Level of agreement between self-reported CVD risk estimation and their actual risk according to the SCORE risk assessment system was compared by calculating weighted Kappa (kappa(w)). Overall, 109 responders (38%) self-reported having either pre-existing CVD (only 2%), one or more markedly raised CVD risk factors, a high total risk of fatal CVD (> or =5% in 10 years) or a strong family history of CVD. About half of this cohort (53%) did not know their own total cholesterol level. Less than half (45%) reported having a 10-year risk of fatal CVD of or =5%. Based on the SCORE risk function, the estimated 10-year risk of a fatal CVD event was or =5% risk of such an event. Overall, less than half (46%) of this cohort's self-reported CVD risk corresponded with that calculated using the SCORE risk function (kappa(w)=0.27). Most cardiovascular nurses attending a European conference in 2005 poorly understood their own CVD risk profile, and the agreement between their self-reported 10-year risk of a fatal CVD and their CVD risk using SCORE was only fair. Given the specialist nature of this conference, our findings clearly demonstrate a need to improve overall nursing awareness of the role and importance of systematic CVD risk assessment.

    Innovative care environments are developed for people with dementia to encourage person-centered care. This study aims to investigate whether residents of green care farms that provide 24-hour nursing care participate more in (physical) activities and social interaction compared with residents of other nursing homes. Longitudinal observation study. Nursing homes in the Netherlands (green care farms, traditional nursing homes, and regular small-scale living facilities). A total of 115 nursing home residents at baseline, 100 at follow-up. Ecological momentary assessments (n = 16,860) were conducted using the Maastricht Electronic Daily Life Observation Tool. Residents living at green care farms were compared with residents living in traditional nursing homes and regular small-scale living facilities. The following aspects were collected for this study: the activity performed by the participant or occurring in his or her vicinity, the engagement in the activity, the level of physical activity during the activity, the physical environment (location where the activity occurred), and the level of social interaction during the activity. In total, 9660 baseline observations and 7200 follow-up observations were conducted. Analyses showed that residents of green care farms significantly more often participated in domestic activities (P = .004, SE = 1.6) and outdoor/nature-related activities (P = .003, SE = 0.9), and significantly less often engaged in passive/purposeless activities (P social interaction (P = .006, SE = 1.1), and came outside significantly more (P = .010, SE = 1.1) than residents of traditional nursing homes. Residents of green care farms were significantly more physically active (P = .013, SE = 0.8) than were residents of regular small-scale living facilities. No other significant differences were found. Green care farms can be a valuable alternative to traditional nursing homes. They provide an attractive, homelike environment and

    This study was conducted to determine how closely nurses' perceptions of their clinical judgment abilities matched their demonstrated clinical judgment skills during a simulation. Seventy-four registered nurses participated in a simulation using a video format. After the simulation, the nurses self-assessed their performance using the Lasater Clinical Judgment Rubric. This rubric was then used to rate the nurses' actual performance in the simulation activity. The study results showed a significant discrepancy between nurses' perceptions of their own clinical judgment abilities and their demonstrated clinical judgment skills. Age and length of nursing experience enhanced the difference between the findings of self-assessment and actual performance. Younger nurses and those with 1 year or less of nursing experience were significantly more likely to have self-assessed their abilities at a much higher level compared with their actual skills.

It is an epidemiological, cross-sectional design, with 36 emergency nurses from December 2010 to January 2011. The Bianchi Stress Scale with 57 questions was used. The nurses were at risk for high levels of stress. The most stressful areas were the operation of the unit, conditions of work and personnel administration, and the most stressful activity was the request for equipment review and repair. The difference by Friedman test between the areas was significant (p <0.05, Dunn post-test significant (p <0.05 when compared by peers. The accumulation of management activities with the assistance activities can generate higher levels of stress, it is necessary to invest in improving the work environment and management support to minimize the stress experienced at work.

  20. Applying Antonio Gramsci's philosophy to postcolonial feminist social and political activism in nursing.

    Science.gov (United States)

    2009-07-01

    Through its social and political activism goals, postcolonial feminist theoretical approaches not only focus on individual issues that affect health but encompass the examination of the complex interplay between neocolonialism, neoliberalism, and globalization, in mediating the health of non-Western immigrants and refugees. Postcolonial feminism holds the promise to influence nursing research and practice in the 21st century where health remains a goal to achieve and a commitment for humanity. This is especially relevant for nurses, who act as global citizens and as voices for the voiceless. The commitment of nursing to social justice must be further strengthened by relying on postcolonial theories to address issues of health inequities that arise from marginalization and racialization. In using postcolonial feminist theories, nurse researchers locate the inquiry process within a Gramscian philosophy of praxis that represents knowledge in action.

    Full Text Available Fault deformation characteristics in the northern margin of the Tibetan Plateau before the Menyuan Ms6.4 earthquake are investigated through time-series and structural geological analysis based on cross-fault observation data from the Qilian Mountain–Haiyuan Fault belt and the West Qinling Fault belt. The results indicate: 1 Group short-term abnormal variations appeared in the Qilian Mountain–Haiyuan Fault belt and the West Qinling Fault belt before the Menyuan Ms6.4 earthquake. 2 More medium and short-term anomalies appear in the middle-eastern segment of the Qilian Mountain Fault belt and the West Qinling Fault belt, suggesting that the faults' activities are strong in these areas. The faults' activities in the middle-eastern segment of the Qilian Fault belt result from extensional stress, as before the earthquake, whereas those in the West Qinling Fault belt are mainly compressional. 3 In recent years, moderate-strong earthquakes occurred in both the Kunlun Mountain and the Qilian Mountain Fault belts, and some energy was released. It is possible that the seismicity moved eastward under this regime. Therefore, we should pay attention to the West Qinling Mountain area where an Ms6–7 earthquake could occur in future.

    Physical activity and physical fitness are important for health, functional mobility and performance of everyday activities. To date, little attention has been given to physical activity and physical fitness among nursing home residents with cognitive impairment. Therefore, the main aim of this study was to examine physical activity behavior and physical fitness of institutionalized older adults with cognitive impairment and to investigate their interrelations. Forty-eight older adults with cognitive impairment (83.9±7.7years; 72.9% women) and 22 without cognitive impairment (82.2±8.8years; 54.5% women) participated. Physical activity was objectively assessed with accelerometers and physical fitness components (muscular strength, flexibility, balance, body composition and reaction time) were evaluated with physical fitness field tests. Nursing home residents with cognitive impairment spent only ~1min per day in moderate physical activity and ~89min in light physical activity. In average they accumulated 863 (±599) steps per day and spent 87.2% of the accelerometer wear time in sedentary behavior. Participants' physical fitness components were markedly low and according to the cut-offs used for interpreting the results a great number of nursing home residents had an increased risk of associated health problems, functional impairment and of falling. The performance in some physical fitness tests was positively associated with physical activity. Participants without cognitive impairment had higher levels of physical activity and physical fitness than their counterparts with cognitive impairment. These results indicate that nursing home residents, especially those with cognitive impairment, have low levels of physical activity, spent a high proportion of daytime in sedentary behavior and have low physical fitness. Nursing homes should implement health promotion strategies targeting physical activity and physical fitness of their residents. Copyright © 2017 Elsevier

    Mechanical load during patient handling activities is an important risk factor for low back pain among nursing personnel. The aims of this study were to describe required and actual use of ergonomic devices during patient handling activities and to assess the influence of these ergonomic devices on mechanical load during patient handling activities. For each patient, based on national guidelines, it was recorded which specific ergonomic devices were required during distinct patient handling activities, defined by transferring a patient, providing personal care, repositioning patients in the bed, and putting on and taking off anti-embolism stockings. During real-time observations over ~60 h among 186 nurses on 735 separate patient handling activities in 17 nursing homes, it was established whether ergonomic devices were actually used. Mechanical load was assessed through observations of frequency and duration of a flexed or rotated trunk >30° and frequency of pushing, pulling, lifting or carrying requiring forces 230 N from start to end of each separate patient handling activity. The number of patients and nurses per ward and the ratio of nurses per patient were used as ward characteristics with potential influence on mechanical load. A mixed-effect model for repeated measurements was used to determine the influence of ergonomic devices and ward characteristics on mechanical load. Use of ergonomic devices was required according to national guidelines in 520 of 735 (71%) separate patient handling activities, and actual use was observed in 357 of 520 (69%) patient handling activities. A favourable ratio of nurses per patient was associated with a decreased duration of time spent in awkward back postures during handling anti-embolism stocking (43%), patient transfers (33%), and personal care of patients (24%) and also frequency of manually lifting patients (33%). Use of lifting devices was associated with a lower frequency of forces exerted (64%), adjustable bed and

    Specialist advanced practice nursing in hemoglobinopathies has a rich historical and descriptive literature. Subsequent work has shown that the role is valued by patients and families and also by other professionals. However, there is little empirical research on the complexity of activity of these services in terms of interventions offered. In addition, the work of clinical nurse specialists in England has been devalued through a perception of oversimplification. The purpose of this study was to understand the complexity of expert nursing practice in sickle cell and thalassemia. The approach taken to modeling complexity was used from common methods in mathematical modeling and computational mathematics. Knowledge discovery through data was the underpinning framework used in this study using a priori mined data. This allowed categorization of activity and articulation of complexity. In total, 8966 nursing events were captured over 1639 hours from a total of 22.8 whole time equivalents, and several data sources were mined. The work of specialist nurses in this area is complex in terms of the physical and psychosocial care they provide. The nurses also undertook case management activity such as utilizing a very large network of professionals, and others participated in admission avoidance work and education of patients' families and other staff. The work of nurses specializing in hemoglobinopathy care is complex and multidimensional and is likely to contribute to the quality of care in a cost-effective way. An understanding of this complexity can be used as an underpinning to establishing key performance indicators, optimum caseload calculations, and economic evaluation.

    To describe the prevalence of everyday activity engagement for older people in nursing homes and the extent to which engagement in everyday activities is associated with thriving. Research into residents' engagement in everyday activities in nursing homes has focused primarily on associations with quality of life and prevention and management of neuropsychiatric symptoms. However, the mere absence of symptoms does not necessarily guarantee experiences of well-being. The concept of thriving encapsulates and explores experiences of well-being in relation to the place where a person lives. A cross-sectional survey. A national survey of 172 Swedish nursing homes (2013-2014). Resident (n = 4831) symptoms, activities and thriving were assessed by staff using a study survey based on established questionnaires. Descriptive statistics, simple and multiple linear regression, and linear stepwise multiple regression were performed. The most commonly occurring everyday activities were receiving hugs and physical touch, talking to relatives/friends and receiving visitors, having conversation with staff not related to care and grooming. The least commonly occurring everyday activities were going to the cinema, participating in an educational program, visiting a restaurant and doing everyday chores. Positive associations were found between activity engagement and thriving, where engagement in an activity program, dressing nicely and spending time with someone the resident likes had the strongest positive association with resident thriving. Engagement in everyday activities can support personhood and thriving and can be conceptualized and implemented as nursing interventions to enable residents to thrive in nursing homes. © 2017 John Wiley & Sons Ltd.

    Variations of phenylethanoid glycoside profiles and antioxidant activities in Osmanthus fragrans flowers through the digestive tract were evaluated by a simulated digestion model and UPLC/PDA/MS. Major phenylethanoid glycosides and phenolic acids, namely, salidroside, acteoside, isoacteoside, chlorogenic acid, and caffeic acid, were identified in four cultivars of O. fragrans flowers, and the concentration of acteoside was the highest, being up to 71.79 mg/g dry weight. After simulated digestion, total phenylethanoid glycoside contents and antioxidant activities were significantly decreased. Acteoside was identified as decomposing into caffeic acid, whereas salidroside was found to be stable during simulated digestion. According to Pearson's correlation analysis, acteoside contents showed good correlations with antioxidant activities during simulated digestion (R(2) = 0.994, P < 0.01). In conclusion, acteoside was the major contributor to the antioxidant activity of O. fragrans flowers, and salidroside was considered as the major antioxidant compound of O. fragrans flowers in vivo.

    It is well established that the left inferior frontal gyrus plays a key role in the cerebral cortical network that supports reading and visual word recognition. Less clear is when in time this contribution begins. We used magnetoencephalography (MEG), which has both good spatial and excellent temporal resolution, to address this question. MEG data were recorded during a passive viewing paradigm, chosen to emphasize the stimulus-driven component of the cortical response, in which right-handed participants were presented words, consonant strings, and unfamiliar faces to central vision. Time-frequency analyses showed a left-lateralized inferior frontal gyrus (pars opercularis) response to words between 100-250 ms in the beta frequency band that was significantly stronger than the response to consonant strings or faces. The left inferior frontal gyrus response to words peaked at approximately 130 ms. This response was significantly later in time than the left middle occipital gyrus, which peaked at approximately 115 ms, but not significantly different from the peak response in the left mid fusiform gyrus, which peaked at approximately 140 ms, at a location coincident with the fMRI-defined visual word form area (VWFA). Significant responses were also detected to words in other parts of the reading network, including the anterior middle temporal gyrus, the left posterior middle temporal gyrus, the angular and supramarginal gyri, and the left superior temporal gyrus. These findings suggest very early interactions between the vision and language domains during visual word recognition, with speech motor areas being activated at the same time as the orthographic word-form is being resolved within the fusiform gyrus. This challenges the conventional view of a temporally serial processing sequence for visual word recognition in which letter forms are initially decoded, interact with their phonological and semantic representations, and only then gain access to a speech code.

    To evaluate inter-rater concordance in the valuation of the "Nursing Activities Score". Cross-sectional descriptive study conducted from December 2012 until June 2013 in a general intensive care unit with twelve beds. Three evaluator nurses, simultaneously and independently, through the patient daily charts, scored the nursing workload using Nursing Activities Score scale in all patients admitted over 18 years old. Three hundreds and thirty-nine records were collected. The intra-class correlation coefficient (ICC) between evaluators was 0.92 (0.89-0.94). A perfect concordance was obtained in 39.1% of the items, with 52.2% having a high, and 8.7% having lower concordance, corresponding to two of the items with multiple scoring options. Significant differences between two of the evaluators (P=.049) were found. Although the inter-rater concordance was high, more accurate records are needed to reduce the variability of the items with multiple options and to allow more accuracy in the interpretation and measurement of the data regarding nursing workload.

    The purpose of this study was to determine the association between the presence of occupational health nurses and health promotion activities, relative to the number of employees, and the health promotion policies of the companies. We investigated 3,266 companies with at least 50 employees listed on the Tokyo Stock Exchange. Questionnaires were sent by mail, and employees in charge of health management or promotion were asked about health promotion activities at their own worksites. Logistic regression analysis was performed with each type of health promotion activity (nutrition, exercise, sleep, mental health, smoking cessation, alcohol consumption reduction, and oral health) as dependent variables, and the presence of an occupational health nurse as the independent variable. The results were adjusted for the type of industry, total number of company employees, presence of company health promotion policies, and the presence of an occupational health physician. Responses were received from 415 companies (response rate: 12.7%). Occupational health nurses were present at 172 companies (41.4%). Health promotion activities such as (in order of frequency) mental health (295 companies, 71.1%), smoking cessation (133, 32.0%), exercise (99, 23.9%), nutrition (75, 18.1%), oral health (49, 11.8%), sleep (39, 9.4%), and alcohol consumption reduction (26, 6.3%) were being conducted. Setting worksites with no occupational health nurse as a reference, the odds ratios of each health promotion activity of a worksite with one or more occupational health nurses were calculated. The odds ratios of mental health (2.43, 95% confidence interval: 1.32-4.48), smoking cessation (3.70, 2.14-6.38), exercise (4.98, 2.65-9.35), nutrition (8.34, 3.86-18.03), oral health (4.25, 1.87-9.62), and alcohol consumption reduction (8.96, 2.24-35.92) were significant. Stratified analysis using the number of worksite employees, 499 or fewer and 500 or more, also showed significantly higher odds ratios of

    The function of song is not only to deliver individual's messages, but also to serve as a learning approach to facilitate students' learning. To observe the effectiveness of songs in facilitating students' learning, a Problem-based Learning (PBL) class with twenty students was divided into four groups with five students per group. Each group was asked to write a song based on two given scenarios, to sing the song out loud, and to participate in a follow-up focus group interview afterwards. The four songs reflected the students' understanding of academic knowledge and their perspectives toward the protagonists in the presented scenarios. Two songs are presented in this paper to demonstrate how the approach was carried out in the nursing PBL class. This paper aims to show the implication of song writing and singing in PBL and shed some light on teaching and learning. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Student voice posits that students' unique perspectives on teaching and learning can be used in conjunction with those of educators to create meaningful educational activities. The study aimed to describe nursing students' and educators' experiences during the co-construction of educational activities involving clinical nursing leadership. Qualitative research and development model. The study was conducted at a French-Canadian nursing faculty that provides a 3-year undergraduate program. Five undergraduate nursing students, four nursing educators, and the principal investigator formed the co-construction team. Data collected included all documents (written and audio) related to the co-construction process: three 2-hour team meetings, PI's fieldnotes and a focus group discussion that occurred once the co-construction process was completed. Thematic analysis was performed guided by Paillé and Muchielli's (2010) method. Data analysis revealed two interrelated themes: (1) unique, purposeful collaboration and (2) change that makes a difference. A space described as safe, without hierarchy and that included the "right" people helped the team achieve their objective of creating new educational activities on clinical nursing leadership. The two new learning activities developed by the team were perceived as useful for future nursing students. At the individual level, team members appreciated how co-construction helped them understand teaching and learning from new perspectives. A structured, efficient co-construction process contributed to positive changes in the nursing program and participants. Additional research is required to enhance understanding of the factors that facilitate and hinder student-educator collaboration outside the classroom. Copyright © 2017 Elsevier Ltd.

    To examine the effectiveness of online learning modules for improving physical activity counseling practices among oncology nurses. 
. Randomized, controlled trial.
. Online.
. 54 oncology nurses.
. Oncology nurses were randomly assigned to the learning modules group or control group. The learning modules group completed six online learning modules and quizzes focused on physical activity for cancer survivors, general physical activity principles, and motivational interviewing.
. Percentage of cancer survivors counseled, self-efficacy for physical activity counseling, knowledge of physical activity, and perceived barriers and benefits of physical activity counseling.
. Analyses of covariance revealed no significant difference between the learning modules and control groups in the percentage of cancer survivors that oncology nurses counseled. Significant differences were found in self-efficacy for physical activity counseling and perceived barriers to physical activity counseling at postintervention. 
. The online learning intervention tested in this study improved some parameters of physical activity counseling but did not increase the percentage of cancer survivors that oncology nurses counseled. Additional pilot work is needed to refine the intervention.
. This study suggests the potential utility of an evidence-based online learning strategy for oncology nurses that includes information on physical activity and its benefits in cancer survivorship. The findings offer a framework on how to implement physical activity counseling skills in oncology nursing practice.

    Balanites aegyptiaca Del. (Zygophyllaceae) fruits are traditionally known for the treatment of hyperglycaemia. Several in vitro and in vivo studies proposed some mechanisms of action. However, clinical trials in human beings were never reported to date. To investigate the antidiabetic efficacy of the 70% ethanol extract of the pericarps of B. aegyptiaca (BE) within a nutritional intervention in elderly people. Ultra-performance electrospray ionization-mass spectroscopy (UPLC-ESI-MS/MS) analysis was used for metabolic profiling of BE which was incorporated in hard gelatine capsules (400 mg/day) and tested on 30 type 2 diabetes (T2D) Egyptian patients for 8 weeks. According to sex, age and body mass index participants were divided into two equivalent groups, placebo and treatment. Thirteen compounds were identified in BE using UPLC-ESI-MS/MS analysis among which five steroidal saponins, seven phenolic compounds and a sterol glucoside. At the end of the 8-week treatment, the treated group showed 26.88% decrease in 2 h postprandial plasma glucose relative to 2.6% increase in the placebo group, while fasting plasma glucose was reduced to 10.3%. Treatment with BE capsules for 8 weeks produced significant reduction in the plasma triglyceride, total cholesterol and low-density lipoprotein cholesterol by 9.0, 12.76 and 21.35%, respectively, with 29.8% increase in the high-density lipoprotein cholesterol. Plasma alanine transaminase and aspartate transaminase were reduced by 42.6 and 43.3%, respectively. Administration of the BE capsules to T2D resulted in significant improvements in the glycaemic markers and the lipid profile, without adverse effects or hypoglycaemia.

    Essential features of the neutron activation-mass Spectrometry (NA-MS) technique are described. Applicability of this technique for the simultaneous determination of boron and lithium is demonstrated for a diverse group of biomaterials. NA-MS is a nondestructive analytical technique, and dynamic in nature since its coverage extends to a broad range of concentration levels. Contamination after the irradiation step, extraneous by natural lithium or boron is inconsequential, since only the activation products are the analyted assayed. Coupling the nuclear activation phenomenon which generates 4 He and 3 He (from 10 B and 6 Li, respectively), with the high precision potential of mass spectrometry forms the bases of this technique. Under ideal conditions the detection limit is extendable to pg g -1 concentration ranges and therefore, it is extremely well suited to investigate the natural concentration levels of boron and lithium in biomaterials. The potential of this method for the determination of lithium in biomedical trace element research is of special significance since determination of sub-ppb levels of lithium by other analytical techniques faces serious analytical difficulties mainly due to contamination control and in some cases to insufficiently low detection limits.

    Full Text Available The aim of the present study was to investigate the GC-MS analysis, phytochemical screening, anti-oxidant, thrombolytic and anti-inflammatory activities of methanol extract of leaves of Exacum bicolor. FTIR analysis confirmed the presence of alcohol, phenols, alkanes, aromatic compounds, aldehyde and ethers. GC-MS analysis revealed the presence of eight phyto-constituents. The total phenol, flavonoid and alkaloid contents were 18.0 ± 0.2 mg/GAE/g, 13.1 ± 0.4 mg QE/g and 108.0 ± 1.2 mg AE/g respectively. The DPPH assay exhibited potent anti-oxidant abilities with IC50 8.8 µg/mL. Significant thrombolytic activity was demonstrated by clot lysis method (45.1 ± 0.8%. The methanol extract showed significant membrane stabilization on human red blood cell with IC50 value of 37.4 µg/mL. There was a significant correlation (R2>0.98 with total phenolic content versus anti-oxidant and anti-inflammatory activity. The above results confirmed that E. bicolor could be a promising anti-oxidant, thrombolytic and anti-inflammatory agent.

    Full Text Available This qualitative study explored the impact and appropriateness of structured pro-active care reviews by practice nurses for patients with chronic or recurrent depression and dysthymia within the ProCEED trial. ProCEED (Pro-active Care and its Evaluation for Enduring Depression was a United Kingdom wide randomised controlled trial, comparing usual general practitioner care with structured 'pro-active care' which involved 3 monthly review appointments with practice nurses over 2 years for patients with chronic or recurrent depression.In-depth interviews were completed with 41 participants: 26 patients receiving pro-active care and 15 practice nurses providing this care. Interview transcripts were analysed thematically using a 'framework' approach.Patients perceived the practice nurses to be appropriate professionals to engage with regarding their depression and most nurses felt confident in a case management role. The development of a therapeutic alliance between the patient and nurse was central to this model and, where it appeared lacking, dissatisfaction was felt by both patients and nurses with a likely negative impact on outcomes. Patient and nurse factors impacting on the therapeutic alliance were identified and nurse typologies explored.Pro-active care reviews utilising practice nurses as case managers were found acceptable by the majority of patients and practice nurses and may be a suitable way to provide care for patients with long-term depression in primary care. Motivated and interested practice nurses could be an appropriate and valuable resource for this patient group. This has implications for resource decisions by clinicians and commissioners within primary care.

    Low back pain is common among nurses. Previous studies have shown that the risk of low back pain increases rapidly with greater amounts of physical work and psychological stress, but is inversely related to leisure activities. However, these previous studies were predominantly retrospective in design and not many took account of three factors simultaneously. This 12-month prospective study examined the relationships between work activities, work stress, sedentary lifestyle and new low back pain. A total of 144 nurses from six Hong Kong district hospitals completed a face-to-face baseline interview, which was followed-up by a telephone interview. The main study measures were demographic characteristics, work activities, work stress, physical leisure activities and the nature of new low back pain during the 12-month follow-up period. Level of work stress, quality of relationships at work, level of enjoyment experienced at work, and work satisfaction were self-reported. Fifty-six (38.9%) nurses reported experiencing new low back pain. Sedentary leisure time activity was not associated with new low back pain. Being comparatively new on a ward (adjusted relative risk 2.90), working in bending postures (adjusted relative risk 2.76) and poor work relationships with colleagues (adjusted relative risk 2.52) were independent predictors of new low back pain. The findings of this study suggest that low back pain is a common problem in the population of nurses in Hong Kong. Being comparatively new on a ward, bending frequently during work and having poor work relationships with colleagues are independent predictors of new low back pain. Training for high-risk work activities and ergonomic assessment of awkward work postures are essential. Moreover, relaxation and team-building workshops for nurses, especially those who are less experienced in the type of work on their current ward, are recommended.

    PEGylation, the attachment of polyethylene glycol (PEG) to nanocarriers and proteins, is a widely accepted approach to improving the in vivo efficacy of the non-PEGylated products. However, both PEGylated liposomes and PEGylated proteins reportedly trigger the production of specific antibodies, mainly IgM, against the PEG moiety, which possibly leads to a reduction in safety and therapeutic efficacy of the PEGylated products. In the present study, two monoclonal anti-PEG IgMs — HIK-M09 via immunization with an intravenous injection of PEGylated liposomes (SLs) and HIK-M11 via immunization with a subcutaneous administration of PEGylated ovalbumin (PEG-OVA) were successfully generated. The generated IgMs showed efficient reactivity to mPEG{sub 2000} conjugated to 1,2-distearoyl-sn-glycero-3-phospho-ethanolamine (DSPE), PEGylated liposome (SL) and PEG-OVA. It appears that HIK-M09 recognizes ethoxy (OCH{sub 2}CH{sub 2}) repeat units along with a terminal motif of PEG, while HIK-M11 recognizes only ethoxy repeat units of PEG. Such unique properties allow HIK-M09 to bind with dense PEG. In addition, their impact on the in vivo clearance of the PEGylated products was investigated. It was found that the generated ant-PEG IgMs induced a clearance of SL as they were intravenously administered with SL. Interestingly, the HIK-M11, generated by PEG-OVA, induced the clearance of both SL and PEG-OVA, while the HIK-M09, generated by SL, induced the clearance of SL only. We here revealed that the presence of serum anti-PEG IgM and the subsequent binding of anti-PEG IgM to the PEGylated products are not necessarily related to the enhanced clearance of the products. It appears that subsequent complement activation following anti-PEG IgM binding is the most important step in dictating the in vivo fate of PEGylated products. This study may have implications for the design, development and clinical application of PEGylated products and therapeutics. - Highlights: • Two monoclonal

    2016-09-01

    This paper reports on the learning potential of a reflective activity undertaken by final year nursing students, in which they were asked to recount two meaningful events that occurred during their clinical placements over the duration of their 3-year nursing degree program and reflect on how these events contributed to their learning to become beginning level Registered Nurses (RNs). This descriptive qualitative study gathered narratives from 92 students as individual postings in an online forum created within the University's learning management system. An analysis of the students' reflections are the focus of this paper particularly in relation to the value of reflecting on the identified events. Four themes emerged that clearly highlight the way in which these students interpreted and learned from both positive and negative clinical experiences, their strong desire to fit into their new role and their ability to re-imagine how they might respond to clinical events when they become Registered Nurses. The findings of this study may contribute to developing nursing curricula that better prepares final year students for the realities of practice. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Clinical nurse specialists (CNSs) frequently adapt to meet the challenging and changing needs of patients, families, nurses, physicians, and institutions, thus creating an advance practice role that is problematic in definition and description. The two dilemmas associated with CNSs have been role confusion and ambiguity, and the inability to explicate CNSs' value in economic terms. The purpose of this study was to describe the roles, activities, skills, and the cost-saving and revenue-generating activities of Master's-prepared nurses who function in traditional CNS roles in the United States. A descriptive research design was employed, using Role Theory as a framework to guide the study. The tool used to measure CNS practice included a 68-item instrument. It was pretested and used in two pilot studies. Content validity was supported by three experienced CNSs who were, at the time, in a doctoral nursing program. Instrument reliability was 0.89. Surveys were mailed to all individuals who subscribed (n = 2379) to the Clinical Nurse Specialist Journal. From the convenience sample, 724 CNSs participated, providing a margin of error of +/- 4 percentage points with a 99% confidence level. Regarding the five role components, CNSs reported (listed from most frequently to least frequently) spending time in the role of expert practitioner, educator, consultant, administrator, and researcher. Most of the activities listed in each of the roles were typical of CNS practice. Of the advanced practice roles, the two with the most surprising results were the expert practitioner and administrator roles. The results indicated a trend toward performing advanced skills that have been in the past considered solely medical practice and toward increasing administrative responsibilities. A small number of CNSs were able to identify cost-saving and revenue-generating activities, including the monetary value of the activity.

    Full Text Available Background There are some mediators that affect physical activity such as knowledge and attitude. Some barriers such as lack of time, bad environments may impede doing physical activities. It sounds that lack of time is a common barrier to do physical activity in nursing and midwifery students. Since they encounter some factors that affect their health, this knowledge, attitude and practice (KAP study may be helpful to maintain and improve their health. Objectives The current study aimed to explore the knowledge, attitude and practice related to physical activity in nursing and midwifery students. Patients and Methods By simple randomized sampling method, 200 subjects were enrolled in the study. Based on the international physical activity questionnaire (IPAQ, a standard checklist was used to gather the related data. Then, the data were analyzed by SPSS software in 95% confidence interval (CI. Results Mean and standard deviation of subjects’ attitude was 5.9 ± 3.1 (minimum: -3, maximum: 14, median: 6. There was no significant difference in the means of knowledge and attitude between genders, and also between nursing and midwifery students. There was significant difference only regarding walking (P = 0.017, stretching (P = 0.050 and body building (P = 0.040 between the students in 95% CI. Conclusions Based on the current study finding, planning is needed to increase KAP of the students regarding physical activity. Some types of physical activity are more attractive than others for males and females separately, yet it is important to encourage the nursing and midwifery students to examine a variety of physical activities and help them find suitable activities.

    Time-driven activity-based costing was applied to analyze the nursing activity cost and efficiency of a medical unit. Data were collected at a medical unit of a general hospital. Nursing activities were measured using a nursing activities inventory and classified as 6 domains using Easley-Storfjell Instrument. Descriptive statistics were used to identify general characteristics of the unit, nursing activities and activity time, and stochastic frontier model was adopted to estimate true activity time. The average efficiency of the medical unit using theoretical resource capacity was 77%, however the efficiency using practical resource capacity was 96%. According to these results, the portion of non-added value time was estimated 23% and 4% each. The sums of total nursing activity costs were estimated 109,860,977 won in traditional activity-based costing and 84,427,126 won in time-driven activity-based costing. The difference in the two cost calculating methods was 25,433,851 won. These results indicate that the time-driven activity-based costing provides useful and more realistic information about the efficiency of unit operation compared to traditional activity-based costing. So time-driven activity-based costing is recommended as a performance evaluation framework for nursing departments based on cost management.

    Full Text Available Abstract Securigera securidaca (L. Degen & Döefl., Fabaceae, has been widely used in the Iranian, Indian and Egyptian folk medicine as antidiabetic and anti-hyperlipidemic remedy. Phenolic profiling of the ethanolic extract (90% of the flowers of S. securidaca was performed via HPLC-DAD-MS/MS analysis in the positive and negative ion modes. The total polyphenols and flavonoids in the flowers were determined colorimetrically, and the quantification of their components was carried out using HPLC-UV. Total phenolics and flavonoids estimated as gallic acid and rutin equivalents were 82.39 ± 2.79 mg/g and 48.82 ± 1.95 mg/g of the dried powdered flowers, respectively. HPLC-DAD-MS/MS analysis of the extract allowed the identification of 39 flavonoids and eight phenolic acids. Quantitative analysis of some flavonoids and phenolics (mg/100 g powdered flowers revealed the presence of isoquercetrin (3340 ± 2.1, hesperidin (32.09 ± 2.28, naringin (197.3 ± 30.16, luteolin (10.247 ± 0.594, chlorogenic acid (84.22 ± 2.08, catechin (3.94 ± 0.57 and protocatechuic acid (34.4 ± 0.15, in the extract. Moreover, the acute toxicity, hypoglycemic and hypolipidemic effects of the extract were investigated using alloxan induced diabetes in rats in a dose of 100, 200, and 400 mg/kg bwt. The ethanolic extract was safe up to a dose of 2000 mg/kg. All tested doses of the flower extract showed marked decrease in blood glucose level by 31.78%, 66.41% and 63.8% at 100, 200 and 400 mg/kg bwt, respectively, at p < 0.05. Regarding the anti-hyperlipidemic effect, a dose of 400 mg/kg of the flower extract showed the highest reduction in serum triacylglycerides and total cholesterol levels (68.46% and 51.50%, respectively at p < 0.05. The current study proved the folk use of the flowers of S. securidaca as anti-diabetic and anti-hyperlipidemic agent which could be attributed to its high phenolic content.

  12. MicroRNAs miR-17 and miR-20a inhibit T cell activation genes and are under-expressed in MS whole blood.

    Full Text Available It is well established that Multiple Sclerosis (MS is an immune mediated disease. Little is known about what drives the differential control of the immune system in MS patients compared to unaffected individuals. MicroRNAs (miRNAs are small non-coding nucleic acids that are involved in the control of gene expression. Their potential role in T cell activation and neurodegenerative disease has recently been recognised and they are therefore excellent candidates for further studies in MS. We investigated the transcriptome of currently known miRNAs using miRNA microarray analysis in peripheral blood samples of 59 treatment naïve MS patients and 37 controls. Of these 59, 18 had a primary progressive, 17 a secondary progressive and 24 a relapsing remitting disease course. In all MS subtypes miR-17 and miR-20a were significantly under-expressed in MS, confirmed by RT-PCR. We demonstrate that these miRNAs modulate T cell activation genes in a knock-in and knock-down T cell model. The same T cell activation genes are also up-regulated in MS whole blood mRNA, suggesting these miRNAs or their analogues may provide useful targets for new therapeutic approaches.

  14. Characterization of estrogen and androgen activity of food contact materials by different in vitro bioassays (YES, YAS, ERα and AR CALUX and chromatographic analysis (GC-MS, HPLC-MS.

    Directory of Open Access Journals (Sweden)

    Johannes Mertl

    Full Text Available Endocrine active substances (EAS show structural similarities to natural hormones and are suspected to affect the human endocrine system by inducing hormone dependent effects. Recent studies with in vitro tests suggest that EAS can leach from packaging into food and may therefore pose a risk to human health. Sample migrates from food contact materials were tested for estrogen and androgen agonists and antagonists with different commonly used in vitro tests. Additionally, chemical trace analysis by GC-MS and HPLC-MS was used to identify potential hormone active substances in sample migrates. A GC-MS method to screen migrates for 29 known or potential endocrine active substances was established and validated. Samples were migrated according to EC 10/2011, concentrated by solid phase extraction and tested with estrogen and androgen responsive reporter gene assays based on yeast cells (YES and YAS or human osteoblast cells (ERα and AR CALUX. A high level of agreement between the different bioassays could be observed by screening for estrogen agonists. Four out of 18 samples tested showed an estrogen activity in a similar range in both, YES and ERα CALUX. Two more samples tested positive in ERα CALUX due to the lower limits of detection in this assay. Androgen agonists could not be detected in any of the tested samples, neither with YAS nor with AR CALUX. When testing for antagonists, significant differences between yeast and human cell-based bioassays were noticed. Using YES and YAS many samples showed a strong antagonistic activity which was not observed using human cell-based CALUX assays. By GC-MS, some known or supposed EAS were identified in sample migrates that showed a biological activity in the in vitro tests. However, no firm conclusions about the sources of the observed hormone activity could be obtained from the chemical results.

    Six impurities were detected at trace level in rivastigmine tartrate drug substance by a newly developed high performance liquid chromatography method. Three impurities were characterized rapidly and three impurities were found to be unknown. The unknown impurities were enriched and identified with a combination of semi-preparative HPLC and LC/MS/MS techniques. Proposed structures were further confirmed by characterization using NMR, FT-IR, and EA techniques of impurity standards. Based on the spectroscopic, spectrometric and elemental analysis data unknown impurities were characterized as 3-[1-(dimethylamino)ethyl]phenyl N-ethyl-N-methyl carbamate N-oxide, ethyl-methyl-carbamic acid 4-(1-dimethylamino-ethyl)-phenyl ester and ethyl-methyl-carbamic acid 2-(1-dimethylamino-ethyl)-phenyl ester. A plausible mechanism for the formation of these impurities is also proposed. The method was validated according to ICH guidelines for fourteen impurities to demonstrate specificity, precision, linearity, accuracy and stability indicating nature of the method. Regression analysis showed correlation coefficient value greater than 0.999 for rivastigmine tartrate and its impurities. Accuracy of the method was established based on the recovery obtained between 93.41 and 113.33% for all impurities. Copyright © 2011 Elsevier B.V. All rights reserved.

  16. Activity in the lateral occipital cortex between 200 and 300 ms distinguishes between physically identical seen and unseen stimuli

    Full Text Available There is converging evidence that electrophysiological responses over posterior cortical regions in the 200-300 ms range distinguish between physically identical stimuli that reach consciousness or remain unseen. Here, we attempt at determining the sources of this awareness-related activity using MEG. Fourteen subjects were presented with faint colored gratings at threshold for contrast and reported on each trial whether the grating was seen or unseen. Subjects were primed with a color cue that could be congruent or incongruent with the color of the grating, to probe to what extent two co-localized features (color and orientation would be bound in consciousness. The contrast between neural responses to seen and unseen physically identical gratings revealed a sustained posterior difference between 190 and 350 ms, thereby replicating prior studies. We further show that the main sources of the awareness-related activity were localized bilaterally on the lateral convexity of the occipito-temporal region, in the lateral occipital (LO complex, as well as in the right posterior infero-temporal region. No activity differentiating seen and unseen trials could be observed in frontal or parietal regions in this latency range, even at lower threshold. Color congruency did not improve gratings' detection, and the awareness-related activity was independent from color congruency. However, at the neural level, color congruency was processed differently in grating-present and grating-absent trials. The pattern of results suggests the existence of a neural process of color congruency engaging left parietal regions that is affected by the mere presence of another feature, whether this feature reaches consciousness or not. Altogether, our results reveal an occipital source of visual awareness insensitive to color congruency, and a simultaneous parietal source not engaged in visual awareness, but sensitive to the manipulation of co-localized features.

    Evaluation of doctoral programs in nursing is becoming more important with the rapid increase in the programs in Japan. This study aimed to evaluate doctoral nursing programs by faculty members and to analyze the relationship of the evaluation with educational and research activities of faculty members in Japan. Target settings were all 46 doctoral nursing programs. Eighty-five faculty members from 28 programs answered the questionnaire, which included 17 items for program evaluation, 12 items for faculty evaluation, 9 items for resource evaluation, 3 items for overall evaluations, and educational and research activities. A majority gave low evaluations for sources of funding, the number of faculty members and support staff, and administrative systems. Faculty members who financially supported a greater number of students gave a higher evaluation for extramural funding support, publication, provision of diverse learning experiences, time of supervision, and research infrastructure. The more time a faculty member spent on advising doctoral students, the higher were their evaluations on the supportive learning environment, administrative systems, time of supervision, and timely feedback on students' research. The findings of this study indicate a need for improvement in research infrastructure, funding sources, and human resources to achieve quality nursing doctoral education in Japan.

    Full Text Available Objective. to determine the evidence-based practice (EBP competence of Spanish and Latin-American nurses participating in professional forums on the Internet and estimate the influence of socio-demographic and professional factors on their competence, which was defined as knowledge of, attitude towards, and implementation of EBP. Methodology: An online survey was administered to a convenience sample of nurses active in Internet forums, comprising validated Spanish versions of the Evidence-Based Practice Questionnaire (EBPQ and Practice Environment Scale of the Nursing Work Index (PES-NWI and socio-demographics and professional variables. Results: 314 questionnaires were obtained (76.96%. The mean EBPQ score was 5.02 out of 7 (95%CI, 4.89-5.14. The variables associated with a higher competence in EBP were academic level, (p<03001, professional category (p=0.001, country of work (p<0.001, perception of practice environment (p=0,018 and research activities (p<0,036. Conclusions: These nurses showed a moderate level of EBP competence. They revealed a positive attitude towards EBP and achieved intermediate scores in both EBP-related skills and knowledge and their implementation. Higher academic levels and professional categories were associated with greater EBP competence. A practice environment perceived to be unfavorable has a negative influence on EBP implementation.

    Education that captures the attention of students is an essential aspect of promoting meaningful, active learning. Rather than standing at the front of a group of learners simply speaking about a topic, teachers have the opportunity of livening up their teaching with humour, games, and other fun activities. This article critically evaluates the benefits and limitations of humour within nursing education as well as the use of games and fun activities as teaching strategies. Examples of various games and interactive activities are also provided. Copyright 2009 Elsevier Ltd. All rights reserved.

    Plants of the Allium genus produce sulphur compounds that give them a characteristic (alliaceous) flavour and mediate for their medicinal use. In this study, the chemical composition and antimicrobial properties of Allium cepa red cv. and A. sativum in the context of three different drying processes were assessed using metabolomics. Bulbs were dried using either microwave, air drying, or freeze drying and further subjected to chemical analysis of their composition of volatile and non-volatile metabolites. Volatiles were collected using solid phase micro-extraction (SPME) coupled to gas chromatography-mass spectrometry (GC/MS) with 42 identified volatiles including 30 sulphur compounds, four nitriles, three aromatics, and three esters. Profiling of the polar non-volatile metabolites via ultra-performance liquid chromatography coupled to high resolution MS (UPLC/MS) annotated 51 metabolites including dipeptides, flavonoids, phenolic acids, and fatty acids. Major peaks in GC/MS or UPLC/MS contributing to the discrimination between A. sativum and A. cepa red cv. were assigned to sulphur compounds and flavonoids. Whereas sulphur conjugates amounted to the major forms in A. sativum , flavonoids predominated in the chemical composition of A. cepa red cv. With regard to drying impact on Allium metabolites, notable and clear separations among specimens were revealed using principal component analysis (PCA). The PCA scores plot of the UPLC/MS dataset showed closer metabolite composition of microwave dried specimens to freeze dried ones, and distant from air dried bulbs, observed in both A. cepa and A. sativum . Compared to GC/MS, the UPLC/MS derived PCA model was more consistent and better in assessing the impact of drying on Allium metabolism. A phthalate derivative was found exclusively in a commercial garlic preparation via GC/MS, of yet unknown origin. The freeze dried samples of both Allium species exhibited stronger antimicrobial activities compared to dried specimens

    Nursing home residing older adults often experience fear of sickness or death, functional impairment and pain. It is difficult for these older adults to maintain a physically active lifestyle and to keep a positive outlook on life. This study evaluated the changes in quality of life, attitude to aging, assertiveness, physical fitness and body composition of nursing home residing elderly through a 15-week organized resistance training based physical activity program. Inactive older adults living in a state financed nursing home (N.=45) were randomly divided into two intervention groups and a control group. Both intervention groups were assigned to two physical activity sessions a week, but one of these groups also had weekly discussions on health and quality of life (Mental group). Data on anthropometric measures, fitness performance, as well as quality of life and attitudes to aging survey data were collected. Due to low attendance rate 12 subjects were excluded from the analyses. Statistical analysis included Paired Samples t-tests and Repeated Measures Analysis of Variance. Both intervention groups significantly improved their social participation, and their upper- and lower-body strength scores. Also, subjects in the Mental group showed improvement in agility fitness test and certain survey scales. No positive changes were detected in attitude towards aging and body composition measures in any groups. The post-hoc results suggest that Mental group improved significantly more than the Control group. Regular physical activity with discussions on health and quality of life made a more meaningful difference for the older adults living in nursing home than physical activity alone. Due to the fact that all participants were influenced by the program, it is suggested to further explore this area for better understanding of enhanced quality of life.

    Ten new (1-10) and ten known (11-20) diterpenoids involving ent-atisane, ent-seco-atisane, ent-kaurane and ent-seco-kaurane types were isolated from Sapium insigne under the guidance of LCMS-IT-TOF analyses. Their structures were characterized by extensive spectroscopic analyses (HRESIMS, UV, IR, 1D and 2D NMR). A putative biosynthetic pathway was proposed for ent-seco-atisane diterpenoids. Their inhibitory activities on α-glucosidase in vitro were tested for the first time. Compound 4 showed moderate inhibitory effect on α-glucosidase with an IC 50 value of 0.34 mM via a noncompetitive inhibition mechanism (K i  = 0.27 mM). The preliminary structure-activity relationships of the ent-atisane diterpenoids inhibiting α-glucosidase were discussed. Copyright © 2018 Elsevier B.V. All rights reserved.

    To discover the current level of nurse-led involvement in activity promotion for older people in primary care and to explore the knowledge and attitudes of primary care nurses about health benefits of activity promotion for older people. The importance of improving and maintaining activity levels in later life is well established. However, intervention studies show that the uptake of and adherence to physical activity programmes by older people are highly variable. The optimal approach to activity promotion for older people is not well understood. Although many activity promotion schemes and evaluations assume that specialist exercise trainers are needed, it remains unclear who is best placed to facilitate activity promotion for older people, and if this is something in which existing primary care practitioners (specifically nurses) could and should take a leading role. This study surveyed all nurses and health visitors working in five primary care organizations in an inner city area. A semi-structured postal questionnaire asked about their knowledge and attitudes to the benefits of exercise in later life, their current levels of involvement in promoting physical activity with older people, and their personal activity levels. The overall response rate was 54% (n=521). The responses of 391 district nurses and practice nurses are presented here. Nurses had the commitment and (depending on the focus of their work) different opportunities to promote physical activity with older patients. There were organizational and individual constraints on their ability to be involved in this aspect of health promotion work themselves, or to refer older people to local activity promotion schemes. Nurses did not have a structured approach when promoting physical activity with older people and had only a partial awareness of the limitations of their knowledge or skills when promoting activity with older people. For promotion of physical activity by older people to be meaningfully

    Based on the motivational sequence described in Self-Determination Theory, this study explored the relationship between relatedness, motivation, adaptation and leisure in nursing homes. We formulated the hypothesis that the variables of the study would be found in an integrative mediational sequence: Participation in leisure activities→Relatedness→Self-determined motivation→Adaptation to nursing homes. Participants (N=112, mean age=84.17) were invited to complete questionnaires assessing these variables. Results of the path analysis found an unsatisfactory fit for this model but revealed another model (Model 2) with a good fit index: Relatedness→Participation in leisure activities→Self-determined motivation→Adaptation to nursing homes→Relatedness. Model 2 fitted better than model 1: the Chi-square values were not significant, Chi 2 (df=2)=5.1, p=0.078 and other indices were satisfactory (CFI=0.930, RMSEA=0.049 and NFI=0.918). These results suggest that feeling connected and secure in the relationships with others, and integrated as an individual to the group contribute to enhance leisure practice, self-determined motivation, and finally adaptation to life environment. Consequently, the relatedness promotes leisure activities practice which represents a central adaptive behavior in nursing homes. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    A fundamental understanding of multitasking within nursing workflow is important in today's dynamic and complex healthcare environment. We conducted a time motion study to understand nursing workflow, specifically multitasking and task switching activities. We used TimeCaT, a comprehensive electronic time capture tool, to capture observational data. We established inter-observer reliability prior to data collection. We completed 56 hours of observation of 10 registered nurses. We found, on average, nurses had 124 communications and 208 hands-on tasks per 4-hour block of time. They multitasked (having communication and hands-on tasks simultaneously) 131 times, representing 39.48% of all times; the total multitasking duration ranges from 14.6 minutes to 109 minutes, 44.98 minutes (18.63%) on average. We also reviewed workflow visualization to uncover the multitasking events. Our study design and methods provide a practical and reliable approach to conducting and analyzing time motion studies from both quantitative and qualitative perspectives.

    Objectives, social role and organization of Italian nursing homes (RSA) are characterized by a pronounced regional differentiation that causes situations which are difficult to compare about expected outcomes. The definition of a functional outcome is particularly difficult in institutionalized patients and this is due to the failure of a conclusive moment of the rehabilitative treatment. Furthermore we often take care of patients who have already been admitted to intensive and/or extensive rehabilitation units time after time, without further functional profit margin. The inconstant presence of professional figures of rehabilitation in nursing homes' staff makes difficult the drafting of an adequate rehabilitative project, especially for the multiple needs of frail old people. Starting with these assumptions, authors hypothesize and adopt a model of sanitary organization to consent a correct allocation of available resources, according to the patient's needs. They stratified all nursing home patients, using the Multidimensional Prognostic Index (MPI) and "Scheda di osservazione intermedia assistenza" (SOSIA), and measured the residual function. They concluded that a multidimensional evaluation of patients allows to identify wellness (of the sick person and of caregivers) as the main objective; nursing home organization could be think as a "complex supportive prosthesis for old people", made by the interaction among structure, operators and activities.

    NUMs' job description in Icelandic hospitals has been revised and now also includes managerial and financial responsibilities. To describe the actual work activities of nurse unit managers (NUMs) in surgical and internal medicine services as self-documented and reflected in their job description. Prospective exploratory study. The study's setting was the largest hospital in Iceland. Data were collected over 7 days from NUMs working on surgical and medical units with an activity diary listing five domains and 41 activities: 'management and planning' (seven activities), 'staff responsibility (seven activities), 'direct clinical work' (five activities), 'service' (12 activities) and 'other' (nine activities). The managers' spent most of their time within the 'other' domain (32% of their time), then the next significant amount of time on 'management and planning' and 'clinical nursing' (19%), and the least amount of time on 'service' (14%). All reported working on two or more activities simultaneously. NUMs made erroneous estimations approximately half of the time about the domain they spent most of their time in and their satisfaction with their work each day varied greatly. The work of NUMs is highly diverse, including undefined miscellaneous tasks and clinical work beyond their job description. © 2017 Nordic College of Caring Science.

    In the present study, chemical composition of fixed oil (NnFO) obtained from Nelumbo nucifera seeds was determined by GC-MS analysis which revealed the presence of 39 compounds mainly comprised of 20.8 % keto fatty acids with high content of methyl ester of palmitic acid (13.59 %) and methyl ester of 9-oxo-nonanoic acid (11.89 %). The other major constituents identified were; fumaric acid-3-methylbut-3-enyl nonyl ester, 2-decenal and methyl ester of 9E-octadecenoic acid as 6.45 %, 5.09 %, 5.06 %, respectively. NnFO along with other fractions were tested for in vitro antimicrobial, antileishmanial and urease inhibitory assays. NnFO showed weak antibacterial activities against the tested bacteria while promising antifungal effect against Candida albicans (68 %), Candida glaberata (65 %) and Aspergillus flavus (64 %). NnFO showed strong antileishmanial activity with IC50 = 7.34 ±0.72 as compared to reference drug (5.1± 0.29) probably due to the presence of keto-ene derivatives. NnFO showed weak urease inhibitory activity while the ethyl acetate fraction (N3) strongly inhibited both J.B. urease (IC50= 21.45 %) and B.P. urease (IC50= 28.65%) respectively. In conclusion, N. nucifera seeds fixed oil possess promising therapeutic potential as a new antifungal and antileishmanial agent. (author)

    Full Text Available A herbal compress used in Thai massage has been modified for use in cellulite treatment. Its main active ingredients were ginger, black pepper, java long pepper, tea and coffee. The objective of this study was to develop and validate an HPLCQTOF-MS method for determining its active compounds, i.e., caffeine, 6-gingerol, and piperine in raw materials as well as in the formulation together with the flavouring agent, camphor. The four compounds were chromatographically separated. The analytical method was validated through selectivity, intra-, inter day precision, accuracy and matrix effect. The results showed that the herbal compress contained caffeine (2.16 mg/g, camphor (106.15 mg/g, 6-gingerol (0.76 mg/g, and piperine (4.19 mg/g. The chemical stability study revealed that herbal compresses retained >80% of their active compounds after 1 month of storage at ambient conditions. Our method can be used for quality control of the herbal compress and its raw materials.

    Stearoyl-CoA desaturase 1 (SCD1) is an enzyme that catalyzes the rate-limiting step in de novo synthesis of monounsaturated fatty acids-mainly oleate and palmitoleate from stearoyl-CoA and palmitoyl-Co A, respectively. These products are the most abundant monounsaturated fatty acids in membrane phospholipids, triglycerides, cholesterol esters. Reports on mice with a targeted disruption of SCD1 gene (SCD1-/-) exhibit improved glucose tolerance and insulin sensitivity compared to wild-type suggesting SCD1 could be a therapeutic target for diabetes and related metabolic diseases. Measurement of SCD1 activity is technically challenging and traditional cell-based SCD1 assay procedure is labor intensive with low throughput. We describe here a novel medium-throughput LC/MS cell-based assay for determining cellular SCD1 activity, facilitating screening of potential SCD1 inhibitor compounds. Confluent HepG2 cells were grown in 24-well plates and incubated with vehicle or an inhibitor followed by incubation with deuterium labeled saturated fatty acid substrates. Total cell lipids were extracted and the conversion of stearate to oleate was measured by liquid chromatography-mass spectrometry. Sterculate, a known inhibitor of SCD1, inhibited the enzyme activity in a dose dependent manner in this assay with a calculated EC 50 of 247 nM. The medium-throughput method described here is an important step towards identifying an inhibitor of SCD1 to treat diabetes and related metabolic diseases

    An enzyme activity assay, based on mass spectrometric (MS) detection of specific reaction product following HPLC separation, has been developed to evaluate pharmaceutical hits identified from primary high throughput screening (HTS) against target enzyme Escherichia coli UDP-N-acetyl-muramyl-L-alanine ligase (MurC), an essential enzyme in the bacterial peptidoglycan biosynthetic pathway, and to study the kinetics of the enzyme. A comparative analysis of this new liquid chromatographic-MS (LC-MS) based assay with a conventional spectrophotometric Malachite Green (MG) assay, which detects phosphate produced in the reaction, was performed. The results demonstrated that the LC-MS assay, which determines specific ligase activity of MurC, offers several advantages including a lower background (0.2% versus 26%), higher sensitivity (> or = 10 fold), lower limit of quantitation (LOQ) (0.02 microM versus 1 microM) and wider linear dynamic range (> or = 4 fold) than the MG assay. Good precision for the LC-MS assay was demonstrated by the low intraday and interday coefficient of variation (CV) values (3 and 6%, respectively). The LC-MS assay, free of the artifacts often seen in the Malachite Green assay, offers a valuable secondary assay for hit evaluation in which the false positives from the primary high throughput screening can be eliminated. In addition, the applicability of this assay to the study of enzyme kinetics has also been demonstrated. Copyright 2004 Elsevier B.V.

    Psidium guajava L. is a plant widely used for food and in folk medicine all over the world. Studies have shown that guava leaves have antifungal properties. In this study, Flavonoid and Tannic fractions were tested to investigate their chemical composition and antifungal potential in vitro.21 compounds in the two fractions, presenting a higher content of phenolic compounds. The antifungal assays were performed against Candida albicans, Candida tropicalis and Candida krusei by microdilution to determine the IC 50 and the cell viability curve. Minimal Fungicidal Concentration(MFC) and the inhibitory effects of the association of the fractions with Fluconazole, as well as the assays used to verify any morphological changes were performed in microculture chambers based on the concentrations from the microdilution. The IC 50 of the isolated fractions and the fractions associated with each other were calculated, varying from 69.29 to 3444.62 μg/mL and the fractions associated with fluconazole varied from 925.56 to 1.57 μg/mL, it was clear that the association of the natural product with the antifungal presented a synergism. The fractions affected pleomorphism capacity and have a potential antifungal activity as they caused fungal inhibition in isolated use, potentiated the action of Fluconazole, reducing its concentration and impeding morphological transition, one of the virulence factors of the genus.

    We report the discovery of a Compton-thick active galactic nucleus (AGN) at z = 4.76 in the 4 Ms Chandra Deep Field South. This object was selected as a V-band dropout in HST/ACS images and previously recognized as an AGN from optical spectroscopy. The 4 Ms Chandra observations show a significant (∼4.2σ) X-ray detection at the V-band dropout position. The X-ray source displays a hardness ratio of HR = 0.23 ± 0.24, which, for a source at z ∼ 5, is highly suggestive of Compton-thick absorption. The source X-ray spectrum is seen above the background level in the energy range of ∼0.9-4 keV, i.e., in the rest-frame energy range of ∼5-23 keV. When fixing the photon index to Γ = 1.8, the measured column density is N H = 1.4 +0.9 -0.5 x 10 24 cm -2 , which is Compton thick. To our knowledge, this is the most distant heavily obscured AGN, confirmed by X-ray spectral analysis, discovered so far. The intrinsic (de-absorbed), rest-frame luminosity in the 2-10 keV band is ∼2.5 x 10 44 erg s -1 , which places this object among type-2 quasars. The spectral energy distribution shows that massive star formation is associated with obscured black hole (BH) accretion. This system may have then been caught during a major coeval episode of BH and stellar mass assembly at early times. The measure of the number density of heavily obscured AGN at high redshifts will be crucial to reconstructing the BH/galaxy evolution history from the beginning.

    Eucalyptus is one of the most important and highly exploited genus in family Myrtaceae. An UPLC/PDA/ESI-qTOF-MS method was adopted to identify Eucalyptus sideroxylon Cunn. ex Woolls leaves phytoconstituents. Cytotoxicity of E. sideroxylon leaves phloroglucinol-rich extract (PGRE) on VERO cells was determined. The antiviral effect of PGRE against hepatitis A (HAV), herpes simplex type 1 (HSV-I), herpes simplex type 2 (HSV-II), coxsackie (CoxB4), and adenoviruses was in vitro evaluated using MTT assay (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide). UPLC-MS analysis allowed the identification of 70 metabolites including: 26 triterpenes, 13 phloroglucinols, 8 fatty acids, 5 flavonoids, 5 oleuropeic acid glucosides, 3 gallic acid derivatives, and 10 miscellaneous. Twenty four metabolites identified in the leaves of E. sideroxylon and four in the genus Eucalyptus are reported herein for the first time. PGRE was found to be non-cytotoxic; the concentration that reduced the cell viability by 50% (CC 50 ) was 0.808mg/mL. Maximum non-toxic concentration (MNTC) of PGRE on Vero cells was 0.312mg/mL. The best antiviral activity was observed against HSV-II. Its mechanism was through decreasing the viral replication (IC 50 189.36μg/mL, 87.65% inhibition) and attachment on Vero cells (IC 50 199.34μg/mL, 83.13% inhibition) rather than virucidal effect (IC 50 293.1μg/mL, 50.68% inhibition). This study provides a complete map for E. sideroxylon leaves composition. It also suggests the plant as a source of new antiviral agents. Copyright © 2017 Elsevier B.V. All rights reserved.

    Excess disability among nursing home elder persons can be prevented or remediated. Because of self-selected disuse and caregiver support of dependency, nursing home residents are likely to develop excess disability. No study was found to test a theory-based program aimed at improving elder persons' self-care abilities for Taiwanese nursing home elder persons who are at risk for developing excess disability. The purpose of this study was to test the effectiveness of a theory-based intervention program on self-care, specifically on activities of daily living (ADLs) performance among nursing home elder persons in Taiwan. A secondary aim was to determine the correlation between ADLs performance and three bliss concepts: life satisfaction, self-esteem, and motivation in health behavior. This study used a quasi-experimental, two-group, pretest-posttest design. Forty-two qualified participants were recruited from two nursing homes located in southern Taiwan and assigned to either the experimental group (n = 21) or the comparison group (n = 21). Participants in the experimental group received the Self-Care Self-Efficacy Enhancement Program (SCSEEP), and those in the comparison group received biweekly social visits for 6 weeks. Levels of ADLs performance were measured by Tappen's Refined ADL Assessment Scale. Life satisfaction was measured by Adams' Life Satisfaction Index A. Self-esteem was measured by Rosenberg's Self-Esteem Scale. Motivation in health behavior was measured by Cox's Health Self-Determinism Index. Elder persons receiving the SCSEEP had significant improvement in feeding, dressing, grooming, and washing activities. Self-esteem (p = .011) and life satisfaction (p = .033) but not motivation in health behavior (p = .282) were positively correlated with levels of ADLs performance. The SCSEEP provides a theory-based intervention model for Taiwanese nursing home elder persons aimed at improving ADLs performance. Further research with a larger sample size is

    Full Text Available Over 59 million workers are employed in the healthcare sector globally, with a daily risk of being exposed to a complex variety of health and safety hazards. The purpose of this study was to investigate the impact of arts activity on the well-being of nursing staff. During October–December 2014, 115 nursing staff working in a hospital, took part in this study, which lasted for 10 weeks. The intervention group (n = 56 took part in silk painting activities once a week. Data was collected using socio-demographic questions, the Warwick-Edinburgh Mental Well-Being Scale, Short Form—36 Health Survey questionnaire, Reeder stress scale, and Multidimensional fatigue inventory (before and after art activities in both groups. Statistical data analysis included descriptive statistics (frequency, percentage, mean, standard deviation, non-parametric statistics analysis (Man Whitney U Test; Wilcoxon signed—ranks test, Fisher’s exact test and reliability analysis (Cronbach’s Alpha. The level of significance was set at p ≤ 0.05. In the intervention group, there was a tendency for participation in arts activity having a positive impact on their general health and mental well-being, reducing stress and fatigue, awaking creativity and increasing a sense of community at work. The control group did not show any improvements. Of the intervention group 93% reported enjoyment, with 75% aspiring to continue arts activity in the future. This research suggests that arts activity, as a workplace intervention, can be used to promote nursing staff well-being at work.

    Chia is a food plant producing seeds which have seen increasing interest owing to their health benefits. This work is the first report on the metabolite profile, total polyphenols and antioxidant activity of chia seeds, determined by ultrasound-assisted extraction, coupled with gas chromatography-mass spectrometry (UAE GC-MS). Different chia sources were compared: two commercial (black and white) and three early flowering (G3, G8 and G17) mutant genotypes. Organic extracts were mainly composed of mono- and polyunsaturated fatty acids with alpha-linolenic being the most abundant. Polar extracts contained sucrose, methylgalactoside and glucose as main sugars. Antioxidant activity and total polyphenolic content were correlated. Chemical composition and yield potential of early flowering genotypes were different from commercial chia, and while white chia showed the highest content of omega-3 fatty acids, the high content of nutraceuticals in G17 and G8 suggests them as a potential source of raw materials for the food/feed industry.

    M. MOBIN

    Full Text Available ABSTRACT Protium heptaphyllum is found in the Amazon region, and in various Brazilian states and South American countries. Also Known as almecega, it produces an oil resin used in traditional medicine as analgesic, anti-inflammatory, cicatrizant and expectorant, it is rich in pentacyclic triterpenes and essential oil. The main objective of this study was to analyze the chemical composition of P. heptaphyllumresin (OEPh over different extraction times and to evaluate their antifungal activity against Candida species, obtained from gardeners with onychomycosis, using the disk diffusion method. The OEPh was obtained by hydrodistillation and analyzed by Multidimensional Gas Chromatography coupled with Mass Spectrometry (MDGC / MS. Candida species were obtained from lesions on the nails of horticulturist from a community garden in the city of Teresina, Piauí, Brazil. The antifungal activity in concentrations of 1000 µg/L, 500 µg/L and 250 µg/L, PROTOCOL M44-A2 (CLSI 2009 OEPh was tested. The main constituents identified were: l-limonene, α-terpineol, p-cineol, o-cymene and α-phellandrene, however, its composition varies significantly with extraction time. All species, except C. rugosa, were inhibited with halo (≥ 14 mm at 1000 μg / L. C. krusei is naturally resistant to the drug fluconazole, but when tested with OEPh the clinical species (case 9 demonstrated sensitivity in three dilutions (halo ≤ 10 ≥ 14 and the standard strain was inhibited at concentration of 1000 μg/Lg / L (halo 14mm. A similar situation also occurred with the standard strain of C. parapsilosis (halo ≥ 11mm. OEPh has considerable antifungal activity, which merits further investigation for alternative clinical applications, since this species is widely distributed in our community, and it presents good yields, and also has important therapeutic applications.

    Piper betle L. is a widely distributed plant in the tropical and subtropical regions, its leaves being largely consumed as a masticator and mouth freshener. The purposes of this work were to characterise the phenolic profile of this species and to improve knowledge of its anti-cholinesterase properties. The phenolic composition of P. betle leaf aqueous and ethanol extracts was characterised by HPLC coupled with a diode-array detector and combined with electrospray ionisation tandem MS, and in vitro cholinesterase inhibitory capacity of both extracts was assessed by spectrophotometric microassays. The effect on neuronal cells (SH-SY5Y) viability was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide reduction and lactate dehydrogenase leakage. Twelve phenolic compounds, comprising a phenylpropanoid, five cinnamoyl and six flavonoids derivatives were identified in P. betle leaves. Hydroxychavicol was the major compound in both extracts; however, the aqueous extract presented a greater diversity of compounds. Both extracts showed strong activity against both acetyl- and butyrylcholinesterase, which can be due, at least partially, to the phenolic composition. Furthermore, the aqueous extract proved to be cytotoxic to human neuroblastoma cells at concentrations higher than 500 µg/mL. The results suggest that the consumption of P. betle leaves as an infusion can have a positive impact in the prevention and treatment of neurodegenerative diseases. Apigenin and luteolin derivatives are reported for the first time in this species. Copyright © 2014 John Wiley & Sons, Ltd.

    2007-02-01

    An HPLC method has been developed and validated for the quantification of the pharmacologically active principles tryptanthrin (1), 1,3-dihydro-3-[(4-hydroxy-3,5-dimethoxyphenyl)methylene]-2 H-indol-2-one (indolinone) (3), indirubin (4), alpha-linolenic acid (2), and indigo (5), an isomer of indirubin, in extracts from the traditional anti-inflammatory plant Isatis tinctoria (woad). The chromatographic separation was performed on a C-18 column with a linear gradient of acetonitrile in water containing 0.1% formic acid. The method combines UV and electrospray MS detection in the positive ion mode for the detection of the alkaloids, with a switch to the negative mode for the analysis of alpha-linolenic acid. The method was applied to the analysis of woad extracts obtained by supercritical fluid (SFE) CO2 extraction, and by pressurized liquid extraction (PLE) with dichloromethane and methanol, respectively. While the highest concentration of alpha-linolenic acid was found in the SFE extract (7.43%), the concentrations of tryptanthrin , indolinone, indirubin and indigo were the highest in the dichloromethane extract (0.30, 0.035, 2.48 and 0.84%, respectively). Compound 3 was not detected in the methanolic extract and only traces of compounds 1, 4 and 5 and low amount of alpha-linolenic acid (0.39%) were present in this extract.

    The adjuvant activity of Chenopodium quinoa (quinoa) saponins on the humoral and cellular immune responses of mice subcutaneously immunized with ovalbumin (OVA) was evaluated. Two quinoa saponin fractions were obtained, FQ70 and FQ90, and 10 saponins were determined by UPLC/Q-TOF-MS. Mice were immunized subcutaneously with OVA alone or adjuvanted with Quil A (adjuvant control), FQ70, or FQ90. FQ70 and FQ90 significantly enhanced the amount of anti-OVA-specific antibodies in serum (IgG, IgG1, and IgG2b) in immunized mice. The adjuvant effect of FQ70 was significantly greater than that of FQ90. However, delayed type hypersensitivity responses were higher in mice immunized with OVA adjuvanted with FQ90 than mice treated with FQ70. Concanavalin A (Con A)-, lipopolysaccharide-, and OVA-stimulated splenocyte proliferation were measured, and FQ90 significantly enhanced the Con A-induced splenocyte proliferation. The results suggested that the two quinoa saponin fractions enhanced significantly the production of humoral and cellular immune responses to OVA in mice.

    Full Text Available Michelle M Lee1, Cameron J Camp2, Megan L Malone21Midwestern University, Department of Behavioral Medicine, Downers Grove, IL , USA; 2Myers Research Institute of Menorah Park Center for Senior Living, Beachwood, OH, USA Abstract: Fourteen nursing home residents on a dementia special care unit at a skilled nursing facility took part in one-to-one intergenerational programming (IGP with 15 preschool children from the facility’s on-site child care center. Montessori-based activities served as the interface for interactions between dyads. The amount of time residents demonstrated positive and negative forms of engagement during IGP and standard activities programming was assessed through direct observation using a tool developed for this purpose – the Myers Research Institute Engagement Scale (MRI-ES. These residents with dementia displayed the ability to successfully take part in IGP. Most successfully presented “lessons” to the children in their dyads, similar to the way that Montessori teachers present lessons to children, while persons with more severe cognitive impairment took part in IGP through other methods such as parallel play. Taking part in IGP was consistently related with higher levels of positive engagement and lower levels of negative forms of engagement in these residents with dementia than levels seen in standard activities programming on the unit. Implications of using this form of IGP, and directions for future research, are discussed.Keywords: Montessori-based activities, intergenerational programming, engagement, dementia

    Most older persons with dementia living in nursing homes spend their days without engaging in much physical activity. This study therefore looked at the influence that the environment has on their level of physical activity, by reviewing empirical studies that measured the effects of environmental stimuli on the physical activity of nursing home residents suffering from dementia. The electronic databases PubMed, PsycINFO, EMBASE, CINAHL and the Cochrane Library were used for the search. The search covered studies published between January 1993 and December 2012, and revealed 3187 abstracts. 326 studies were selected as potentially relevant; of these, 24 met all the inclusion criteria. Positive results on the residents' levels of physical activity were found for music, a homelike environment and functional modifications. Predominantly positive results were also found for the small-scale group living concepts. Mixed results were found for bright or timed light, the multisensory environment and differences in the building footprint. Copyright © 2014 Elsevier Ltd and The Ergonomics Society.

    To describe nursing activities in primary care with patients affected by physical chronic disease and common mental disorders. Patients in primary care who are affected by physical chronic disease and common mental disorders such as anxiety and depression require care and follow-up based on their physical and mental health condition. Primary care nurses are increasingly expected to contribute to the care and follow-up of this growing clientele. However, little is known about the actual activities carried out by primary care nurses in providing this service in the Province of Quebec (Canada). A qualitative descriptive study was conducted. Data were obtained through semistructured individual interviews with 13 nurses practising among patients with physical chronic disease in seven Family Medicine Groups in Quebec (Canada). Participants described five activity domains: assessment of physical and mental health condition, care planning, interprofessional collaboration, therapeutic relationship and health promotion. The full potential of primary care nurses is not always exploited, and some activities could be improved. Evidence for including nurses in collaborative care for patients affected by physical chronic disease and common mental disorders has been shown but is not fully implemented in Family Medicine Groups. Future research should emphasise collaboration among mental health professionals, primary care nurses and family physicians in the care of patients with physical chronic disease and common mental disorders. Primary care nurses would benefit from gaining more knowledge about common mental disorders and from identifying the resources they need to contribute to managing them in an interdisciplinary team. © 2016 John Wiley & Sons Ltd.

    A quantitative method was developed to support therapeutic drug monitoring of eight antipsychotic drugs: chlorpromazine, haloperidol, zuclopenthixol, clozapine, risperidone, quetiapine, aripiprazole or olanzapine and some active metabolites (dehydroaripiprazole, N-desmethylclozapine and 9-hydroxyrisperidone) in human serum. Separation of the compounds was achieved using a Zorbax SB-C18 (150 mm × 4.6 mm, 5 μm) column and mass-spectrometric detection in multiple reaction monitoring mode. Human blood samples were collected in vacutainer tubes and the analytes were extracted with methyl-tert-butyl ether. The lower limits of quantitation were equal 0.5-1 ng/mL for all analytes. The method was applied with success to serum samples from schizophrenic patients undergoing polypharmacy with two or more different antipsychotic drugs. Precision data, accuracy results were satisfactory, and no interference from other psychotropic drugs was found. Hence, the method is suitable for the TDM of the analytes in psychotic patients' serum.

    No scientific consensus has been reached on whether active tobacco smoking causes breast cancer. We examine the association between active smoking and breast cancer risk in Denmark, which has some of the highest smoking and breast cancer rates in women worldwide. We used the data from a nationwide Danish Nurse Cohort on 21,867 female nurses (age > 44 years) who at recruitment in 1993 or 1999 reported information on smoking status, onset, duration, and intensity, as well as breast cancer risk factors. We obtained data on incidence of breast cancer from Danish Cancer Registry until 2013, and used Cox regression models to analyze the association between smoking and breast cancer. Of 21,831 women (mean age 53.2 years) 1162 developed breast cancer during 15.7 years of follow-up. 33.7% of nurses were current and 30.0% former smokers at cohort baseline. Compared to never smokers, we found increased risk of breast cancer of 18% in ever (hazard ratio and 95% confidence interval: 1.18; 1.04-1.34) and 27% in current (1.27; 1.11-1.46) smokers. We detected a dose-response relationship with smoking intensity with the highest breast cancer risk in women smoking >15 g/day (1.31; 1.11-1.56) or >20 pack-years (1.32; 1.12-1.55). Parous women who smoked heavily (>10 pack-years) before first childbirth had the highest risk of breast cancer (1.58; 1.20-2.10). Association between smoking and breast cancer was not modified by menopausal status, obesity, alcohol or hormone therapy use, and seemed to be limited to the estrogen receptor positive breast cancer subtype. Active smoking increases risk of breast cancer, with smoking before first birth being the most relevant exposure window.

  13. Anti-leukemia activity of MS-275 histone deacetylase inhibitor implicates 4-1BBL/4-1BB immunomodulatory functions.

    Full Text Available Histone deacetylase inhibitors (HDACi have demonstrated promising therapeutic potential in clinical trials for hematological malignancies. HDACi, such as SAHA/Vorinostat, Trichostatin A, and MS-275 were found to induce apoptosis of leukemic blasts through activation of the death receptor pathway and transcriptional induction of the Tumor Necrosis Factor (TNF-related pro-apoptotic family members, TRAIL and FasL. The impact of HDACi on TNF-related costimulatory molecules such as 4-1BB ligand (4-1BBL/TNFSF9 is however not known. Following exposure to SAHA/Vorinostat, Trichostatin A, and MS-275, transcript levels were determined by real time PCR in Jurkat, Raji and U937 cells. Treatment with HDACi up-regulated TNFSF9 gene expression in the three leukemia cell lines, yet to different extend and with distinct kinetics, which did not require de novo protein synthesis and was not associated with DNAse I hypersensitive chromatin remodeling. Transcriptional activity of TNFSF9 promoter-luciferase constructs was induced up to 12 fold by HDACi, and implication of Sp1/Sp3 transcription factors binding to functional GC-box elements was evidenced by reporter gene assays, site-directed mutagenesis, and electrophoretic mobility shift assays. Functionality of modulated target genes was assessed in allogeneic mixed leukocyte reaction experiments. MS-275- and to a lesser extent Trichostatin A- and SAHA-treated Raji cells significantly up regulated T lymphocytes proliferation which was reduced by about 50% by a 4-1BB blocking recombinant protein, while MS-275- but neither Trichostatin A- nor SAHA-treated cells up-regulated IFNgamma secretion by T lymphocytes. Our results identify 4-1BBL/4-1BB as a downstream target of HDACi, especially of MS-275 anti-leukemia action in vitro. Thus, HDACi such as MS-275 displaying dual TNF-dependent proapoptotic and costimulatory activities might be favored for inclusion in HDACi-based anti-cancer therapeutic strategies.

    Nurses are the largest group of direct health providers and can serve as role models for their patients. In this cross sectional study we assessed the relationship among physical activity and barriers, shift duty, elevated BMI, and selected eating habits among 362 non-Saudi female nurses in Riyadh, Saudi Arabia. Results showed that 46.7% were either overweight or obese. Marital status, shift duty, education level, and BMI were significant predictors of physical activity. Weather was the most frequently reported barrier to physical activity (88.3%), followed by a lack of transportation (82.6%), and a lack of time (81.3%). Nurses who worked shift duty had significantly (p = 0.004) higher BMIs compared with day shift nurses. Nurses who rarely ate breakfast (p = 0.004) and meals (p = 0.001) and often eat fast food (p = 0.001) were more likely to be overweight or obese. Nurses should be encouraged for a better healthy lifestyles.

    to analyze the interruptions experienced by nursing professionals while undertaking care activities. an observational study undertaken in two intensive care units. Two nurses observed 33 nursing professionals for three hours. The data were recorded in real time, using a semistructured instrument. after 99 hours of observation of 739 activities, it was identified that 46.82% were interrupted, resulting in 7.85 interruptions per hour. On average, the interruptions compromised 9.42% of the nursing professionals' worktime. The activities geared towards indirect care of the patient suffered the highest number of interruptions (56.65%), with the nursing records being the activity interrupted most. The principal source of the interruptions was external, coming from the health professionals (51%), and the main causes were those related to the patients (34.70%) and to interpersonal communication (26.47%). the activity of nursing suffers a high number of interruptions, mainly caused by the health professionals themselves, indicating that the work environment needs to undergo interventions aiming to reduce the risk of compromising of the professional's performance and to increase the patients' safety. analisar as interrupções experienciadas por profissionais de enfermagem durante realização de atividades assistenciais. estudo observacional realizado em duas unidades de tratamento intensivo.

    A rapid, sensitive and specific method using liquid chromatography coupled to tandem mass spectrometry was developed for the simultaneous quantification of hydroxychloroquine (HCQ) and its three major metabolites in human whole blood. The assay, using a sample volume of 100μL, was linear in a dynamic 25-2000ng/mL range (R(2)>0.99) for all four compounds and suitable for the determination of elevated HCQ concentrations up to 20,000ng/mL, after appropriate sample dilution. Inter- and intra-assay precisions were <18.2% and accuracies were between 84% and 113% for any analyte. No matrix effects were observed. The assay was successfully applied to a blood sample obtained from one poisoned patient following a massive HCQ self-ingestion resulting in an estimated concentration of 19,500ng/mL on hospital admission. In this patient, HCQ metabolites were identified and quantified at 1123, 465 and 91ng/mL for monodesethylhydroxychloroquine, desethylchloroquine and bisdesethylchloroquine, respectively. Further investigations are still required to assess the usefulness of the simultaneous measurement of blood concentrations of HCQ and its three active metabolites for monitoring HCQ treatment and managing HCQ poisoning.

    A novel method based on high-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry was developed for simultaneous determination of the 11 major active components including ten flavonoids and one phenolic acid in Cirsium setosum. Separation was performed on a reversed-phase C(18) column with gradient elution of methanol and 0.1‰ acetic acid (v/v). The identification and quantification of the analytes were achieved on a hybrid quadrupole linear ion trap mass spectrometer. Multiple-reaction monitoring scanning was employed for quantification with switching electrospray ion source polarity between positive and negative modes in a single run. Full validation of the assay was carried out including linearity, precision, accuracy, stability, limits of detection and quantification. The results demonstrated that the method developed was reliable, rapid, and specific. The 25 batches of C. setosum samples from different sources were first determined using the developed method and the total contents of 11 analytes ranged from 1717.460 to 23028.258 μg/g. Among them, the content of linarin was highest, and its mean value was 7340.967 μg/g. Principal component analysis and hierarchical clustering analysis were performed to differentiate and classify the samples, which is helpful for comprehensive evaluation of the quality of C. setosum. © 2012 WILEY-VCH Verlag GmbH & Co.

    2007-01-01

    Fourteen nursing home residents on a dementia special care unit at a skilled nursing facility took part in one-to-one intergenerational programming (IGP) with 15 preschool children from the facility's on-site child care center. Montessori-based activities served as the interface for interactions between dyads. The amount of time residents demonstrated positive and negative forms of engagement during IGP and standard activities programming was assessed through direct observation using a tool developed for this purpose--the Myers Research Institute Engagement Scale (MRI-ES). These residents with dementia displayed the ability to successfully take part in IGP. Most successfully presented "lessons" to the children in their dyads, similar to the way that Montessori teachers present lessons to children, while persons with more severe cognitive impairment took part in IGP through other methods such as parallel play. Taking part in IGP was consistently related with higher levels of positive engagement and lower levels of negative forms of engagement in these residents with dementia than levels seen in standard activities programming on the unit. Implications of using this form of IGP, and directions for future research, are discussed.

    The medicinal orchid Dendrobium moniliforme contains water-soluble polysaccharides, phenanthrenes, bibenzyl derivatives, and polyphenol compounds. This study explored the antioxidant and cytotoxic activities of D. moniliforme extracts and detected their bioactive compounds. Plant material was collected from the Daman of Makawanpur district in central Nepal. Plant extracts were prepared from stems using hexane, chloroform, acetone, ethanol and methanol. The total polyphenol content (TPC) in each extract was determined using Folin-Ciocalteu's reagent and the total flavonoid content (TFC) in each extract was determined using the aluminium chloride method. The in vitro antioxidant and cytotoxic activities of each extract were determined using DPPH (2,2-diphenyl-1-picrylhydrazyl) and MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assays respectively. Gas chromatography and mass spectrometry (GC-MS) analysis was used to detect bioactive compounds. TPC content was highest (116.65 μg GAE/mg of extract) in D. moniliforme chloroform extract (DMC) and TFC content was highest (116.67 μg QE/mg of extract) in D. moniliforme acetone extract (DMA). D. moniliforme hexane extract (DMH) extract showed the highest percentage of DPPH radical scavenging activity (94.48%), followed closely by D. moniliforme ethanol extract (DME) (94.45%), DMA (93.71%) and DMC (94.35%) at 800 μg/ml concentration. The antioxidant capacities of DMC, DMA, DMH and DME, which were measured in IC 50 values, were much lower 42.39 μg/ml, 49.56 μg/ml, 52.68 μg/ml, and 58.77 μg/ml respectively than the IC 50 of D. moniliforme methanol extract (DMM) (223.15 μg/ml). DMM at the concentration of 800 μg/ml most inhibited the growth of HeLa cells (78.68%) and DME at the same concentration most inhibited the growth of U251 cells (51.95%). The cytotoxic capacity (IC 50 ) of DMM against HeLa cells was 155.80 μg/ml of extract and that of DME against the U251 cells was 772.50 μg/ml of

    In addition to the underlying health problems and disability associated with multiple sclerosis (MS) and cardiovascular disease (CVD), adults with each of these chronic illnesses are independently known to experience fatigue. While fatigue's influence on physical activity and health related quality of life (HRQOL) with each of these illnesses has been discussed, what is lacking is information on how fatigue impacts physical activity and health related quality of life, and ultimately self-management for adults with these conditions. Additionally, individuals may be unaware of the significance of maintaining optimal physical activity in order to maintain everyday function and self-management. Thus, the purpose of this article is to discuss the complex effect of fatigue on physical activity and HRQOL among adults with MS and CVD, and to present potential self-management strategies.

    2017-01-01

    We report the development of a rapid, simple, and robust LC–MS/MS-based enzyme assay using dried blood spots (DBS) for the diagnosis of pyridox(am)ine 5′-phosphate oxidase (PNPO) deficiency (OMIM 610090). PNPO deficiency leads to potentially fatal early infantile epileptic encephalopathy, severe developmental delay, and other features of neurological dysfunction. However, upon prompt treatment with high doses of vitamin B6, affected patients can have a normal developmental outcome. Prognosis of these patients is therefore reliant upon a rapid diagnosis. PNPO activity was quantified by measuring pyridoxal 5′-phosphate (PLP) concentrations in a DBS before and after a 30 min incubation with pyridoxine 5′-phosphate (PNP). Samples from 18 PNPO deficient patients (1 day–25 years), 13 children with other seizure disorders receiving B6 supplementation (1 month–16 years), and 37 child hospital controls (5 days–15 years) were analyzed. DBS from the PNPO-deficient samples showed enzyme activity levels lower than all samples from these two other groups as well as seven adult controls; no false positives or negatives were identified. The method was fully validated and is suitable for translation into the clinical diagnostic arena. PMID:28782931

    The investigation was conducted to analyse the bioactive compounds from the leaf extracts of L. speciosa by GC-MS. The extracts were screened for antibacterial and antibiofilm activities against potential clinical strains. The bioactive compounds from the leaves of L. speciosa were extracted by soxhlet continuous extraction method and their chemical composition was analysed by Gas Chromatography-Mass Spectroscopy (GC-MS). The antibacterial activity was evaluated against clinical strain like Staphylococcus aureus, Escherichia coli, P. aeruginosa and Salmonella typhi by well diffusion technique. We also screened for antibacterial property against common food borne pathogens namely Listeria monocytogenes and Bacillus cereus at varied concentration 250μml -1 to 1000μml -1 . Thereafter antibiofilm assay was carried out at from 250 to 1000μg/ml against P. aeruginosa (high biofilm forming pathogen) clinical strain by cover slip technique and the morphology of the pathogen was observed using Scanning Electron Microscopy-(SEM). It was observed that diverse class of secondary metabolites were found by GC-MS analysis for all the extracts upon the continuous extraction. It was found that only minimum inhibition was seen in alcoholic extract for antibacterial activity, whereas all other extracts showed negligible activity. P. aeruginosa biofilm inhibited to 93.0±2% and 91±2% at higher concentration (1000μg/ml) for methanolic and ethanolic extract respectively. Absence of extracellular matrix structure and the surface cracking of biofilm were viewed by SEM, which confirmed the antibiofilm activity. Hence this study reveals that L. speciosa showed significant antibiofilm activity against P. aeruginosa due to the phytoconstituents present in the leaf extracts which was well documented in the alcoholic extracts by GC-MS analysis. The methanolic and ethanolic extract showed good photocatalytic activity of 77.44% and 96.66% against azo dye degradation respectively. Further

  4. Issues in reflection and debriefing: how nurse educators structure experiential activities.

    Experiential learning is particularly useful in vocational education programs where theory needs to be linked to practice. Although experiential learning is often advocated in nursing education and the importance of debriefing and reflection is almost always espoused, the focus in the literature has tended to be on detailed descriptions of the action phase with little close analysis of how the reflective phase is facilitated. The Lewinian model described by Kolb [Experiential Learning. Experience as Source of Learning and Development, Prentice-Hall, New Jersey, 1984] and the structuring approach suggested by Thiagarajan [Experiential Learning Packages, Prentice-Hall, Englewood Cliffs, NJ, 1980] have been used as the theoretical context for an exploration of how nurse teachers describe their facilitation of the debriefing and reflective phases of experiential learning activities. Explication of the entire planned experiential learning experience is important for increasing the chances of the student being able to close the experiential learning loop. The more covert reflective phases for facilitating experiential learning are crucial and if neglected, or inexpertly and insensitively handled, may at best lead to poor learning outcomes or at worst lead to emotional damage and ;unfinished business' for the student. Interviews with eight experienced university educators elicited descriptions of how they constructed experiential activities with special reference to their descriptions of how the debriefing or reflective phases were structured.

    To investigate whether immunologic factors in breast milk change in response to nursing infants' infection. Total CD45 leukocyte count dropped from 5,655 (median and interquartile range: 1,911; 16,871) in the acute phase to 2,122 (672; 6,819) cells/ml milk after recovery with macrophage count decreasing from 1,220 (236; 3,973) to 300 (122; 945) cells/ml. Tumor necrosis factor-α (TNFα) levels decreased from 3.66 ± 1.68 to 2.91 ± 1.51 pg/ml. The decrease in lactoferrin levels was of borderline statistical significance. Such differences were not recorded in samples of the controls. Interleukin-10 levels decreased in the sick infants' breast milk after recovery, but also in the healthy controls, requiring further investigation. Secretory immunoglobulin A levels did not change significantly in the study or control group. During active infection in nursing infants, the total number of white blood cells, specifically the number of macrophages, and TNFα levels increase in their mothers' breast milk. These results may support the dynamic nature of the immune defense provided by breastfeeding sick infants. Breast milk from mothers of 31 infants, up to 3 months of age, who were hospitalized with fever, was sampled during active illness and recovery. Milk from mothers of 20 healthy infants served as controls.

    The severe underuse of school nurses leaves students with unaddressed health needs that impact their safety and learning ability. An undergraduate pediatric clinical focusing on nursing students and the role of a school nurse in an elementary school setting can be a unique approach to combining the needs of school children and educating student nurses. One school of nursing created such a project to help address these needs and collect data on the activities student nurses performed in school nurse role and their impact on student health. This project serves as both a practice improvement project and an innovation in pediatric clinical education. The purposes of this project were to quantify baccalaureate nursing student activities related to the school nurse role and to evaluate the results that have the potential to impact on student health in an urban elementary school.

    Low back pain (LBP) remains a common and costly problem among the nursing profession. Several studies have indicated that LBP is attributed to mentally straining or demanding work, fatigue or exhaustion or general work satisfaction. This study aims to measure the magnitude of LBP among Hong Kong nurses and its association with the work-related psychological strain and patients handling activities. RESEARCH METHODS AND MEASURES: A cross-sectional study of Hong Kong hospital nurses was conducted. Three hundred and seventy-seven nurses were recruited from six district hospitals. They were registered nurses or enrolled nurses working full-time for at least 1 month in the current ward. One hundred and seventy-eight (47.2%) study subjects were randomly selected from two district hospitals and 199 (52.8%) study nurses made up the convenience sample. Possible bias from psychological distress, socio-demographics and lifestyle factors was controlled for. Data were collected by face-to-face interviews. The data included work factors (both psychological stress and patient handling activities related to work), demographics, psychological distress and lifestyle factors and the occurrence of LBP. Of the 377 nurses interviewed, 153 (40.6%) reported having LBP within the last 12 months. With symptoms of LBP as the outcome, risks were increased where nurses self-reported that they only occasionally or never enjoyed their work [adjusted odds ratio (OR) 2.07], where frequent manual repositioning of patients on the bed was required (adjusted OR 1.84) and where they were required to assist patients while walking (adjusted OR 2.11) after adjustment for other potential confounders. The results indicate that an association exists between work stress, manual lifting and LBP prevalence. The main route to prevention of LBP among nurses is likely to lie in improved ergonomics and psychological health in their work place.

    Activated carbon fiber (ACF) as extraction fiber for solid-phase microextraction (SPME) and its application for the analysis of banned organochlorine pesticides (OCPs) were investigated. Firstly, ACF was activated by different concentration of zinc chloride, which indicated that ACF activated by 60% zinc chloride had a reasonable specific surface area, pore volume and pore distribution. Secondly, the parameters for the ACF-SPME procedure, the adsorption and desorption conditions, were also optimized when coupled with gas chromatography-mass spectrometry (GC-MS). Thirdly, the ACF-SPME was used to analyze 17 kinds of OCPs in water. The linearity of most pesticides was found to be between 0.2 and 50 microg/l with GC-MS under the selected ion monitoring (SIM) acquisition mode. The limits of detection (LOD) at the sub microg/l were obtained. The work demonstrated here shows that ACF is a promising alternative for the SPME procedure.

    We have synthesized a homobifunctional amine-reactive cross-linking reagent, containing a TEMPO (2,2,6,6-tetramethylpiperidine-1-oxy) and a benzyl group (Bz), termed TEMPO-Bz-linker, to derive three-dimensional structural information of proteins. The aim for designing this novel cross-linker was to facilitate the mass spectrometric analysis of cross-linked products by free radical initiated peptide sequencing (FRIPS). In an initial study, we had investigated the fragmentation behavior of TEMPO-Bz-derivatized peptides upon collision activation in (+)-electrospray ionization collision-induced dissociation tandem mass spectrometry (ESI-CID-MS/MS) experiments. In addition to the homolytic NO-C bond cleavage FRIPS pathway delivering the desired odd-electron product ions, an alternative heterolytic NO-C bond cleavage, resulting in even-electron product ions mechanism was found to be relevant. The latter fragmentation route clearly depends on the protonation of the TEMPO-Bz-moiety itself, which motivated us to conduct (-)-ESI-MS, CID-MS/MS, and MS 3 experiments of TEMPO-Bz-cross-linked peptides to further clarify the fragmentation behavior of TEMPO-Bz-peptide molecular ions. We show that the TEMPO-Bz-linker is highly beneficial for conducting FRIPS in negative ionization mode as the desired homolytic cleavage of the NO-C bond is the major fragmentation pathway. Based on characteristic fragments, the isomeric amino acids leucine and isoleucine could be discriminated. Interestingly, we observed pronounced amino acid side chain losses in cross-linked peptides if the cross-linked peptides contain a high number of acidic amino acids. Graphical Abstract ᅟ.

    A number of studies across different disciplines have investigated students' learning styles. Differences are known to exist between graduate and baccalaureate nursing students. However, few studies have investigated the learning styles of students in graduate entry nursing programs. . Study objective was to describe graduate entry nursing students' learning styles. A descriptive design was used for this study. The Index of Learning Styles (ILS) was administered to 202 graduate entry nursing student volunteers at a southwestern university. Descriptive statistics, tests of association, reliability, and validity were performed. Graduate nursing students and faculty participated in data collection, analysis, and dissemination of the results. Predominant learning styles were: sensing - 82.7%, visual - 78.7%, sequential - 65.8%, and active - 59.9%. Inter-item reliabilities for the postulated subscales were: sensing/intuitive (α=0.70), visual/verbal (α=0.694), sequential/global (α=0.599), and active/reflective (α=0.572). Confirmatory factor analysis for results of validity were: χ 2 (896)=1110.25, pnursing students. This study provided faculty with numerous opportunities for actively engaging students in data collection, analysis, and dissemination of results. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To analyze the history of the life and activism of Portuguese nurse Maria Augusta Sousa. Sousa's life story was obtained by means of semi-structured interview swith Sousa as the oral source of data. NVivo qualitative research software was used for data analysis. Content analysis focused on thematic analysis based on the theoretical and philosophical ideas of Michel Foucault, in particular, power and techniques of the self. Alienation and political participation were revealed as pertinent issues. In techniques of production of activist subjects, the following were highlighted: the importance of the review of formal education; actions of involvement with the world, society and the profession; and finally, techniques of the self, techniques of constitution of activist subjects, professional identity and way of being. The constitution of the nurse Maria Augusta Sousa as an activist came about through questioning of how to be, education in the context of her family, and political engagement in Catholic Youth. This impacted her trajectory of contributions to Portuguese nursing, as expressed in the following achievements: the integration of nursing training into higher education; the creation of the Regulation of Nurses Professional Practice; and implementation of the Order of Nurses.

    The analytical methods for the determination of major elements (Al, Ca, K, Fe, Mg) in sediment have been investigated with ICP-MS. The analytical results of major elements with Cool ICP-MS were much better than those with normal ICP-MS. The analytical results were compared with those of NAA. NAA were a little superior to ICP-MS for the determination of major elements in sediment, and NAA is a non-destructive analytical method. The analytical methods for the determination of minor elements (Cr, Ce, U, Co, Pb, As, Se) in sediment have been also studied with ICP-MS. The analytical results by standard calibration with ICP-MS were not accurate due to matrix interferences. Thus, internal standard method was applied, then the analytical results for minor element with ICP-MS were greatly improved. The analytical results obtained by ICP-MS were compared with those obtained by NAA. It showed that the two analytical methods have great capabilities for the determination of minor elements in sediments

    Using acid-catalyzed degradation in the presence of cysteamine, the condensed tannins from Lithocarpus glaber leaves were characterized, following thiolysis, by means of reversed-phase HPLC, 13C-NMR and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) analyses. The thiolysis reaction products showed the presence of the procyanidin (PC) and prodelphinidin (PD) structures. The 13C-NMR spectrum revealed that the condensed tannins were comprised of PD (72.4%) and PC (27.6%), and with a greater content of cis configuration rather than the trans configuration of C2-C3. The MALDI-TOF MS analysis proved the presence of PD units, and the maximum degree of polymerization (DP) was an undecamer. The antioxidant activity of condensed tannins from L. glaber leaves was evaluated by using a free radical scavenging activity assay.

    2018-03-01

    Hospital nurses play an important role in the nation's short- and long-term patient care. At the same time, nurses often experience high levels of occupational stress and participate in low levels of physical activity (PA). The purpose of this study was to examine the impact of self-monitoring and a poster campaign on the PA behaviors of hospital nurses. Motivational and instructional exercise posters were hung in break rooms of experimental units and replaced biweekly for 8 weeks. A total of 26 nurses (control: n = 13; experimental: n = 13) wore accelerometers for 3 workdays pre-, mid-, and postintervention. Participants were provided a step counter at baseline and a PA report at each stage. Moderate to vigorous PA (MVPA) and step count (SC) increased pre- to midintervention for control (MVPA: 14.8 ± 7.6%; SC: 19.1 ± 7.8%) and experimental (MVPA: 26.7 ± 18.5%, SC: 17.6 ± 8.3%) participants. Physical activity levels returned to baseline postintervention for control ( p > .05) and increased mid- to postintervention for experimental (MVPA: 16.2 ± 5.2%, SC: 10.7 ± 4.7%, p poster campaign may increase PA levels of hospital nurses when combined with personalized PA feedback.

    To explore depressive symptoms among nursing home residents without cognitive impairment and the relationship between their depressive symptoms and dependence on activities of daily living, comorbidity and sociodemographic variables. Depression has become a major health care concern among older people, but depression and its association with functioning in activities of daily living among nursing home residents without cognitive impairment has previously not been studied in Norway. A cross-sectional comparative design. The sample comprised older residents (age 65-102 years; n = 227) from 30 nursing homes with at least six months of residence. All nursing home residents had a Clinical Dementia Rating scale score ≤0·5 and were capable of conversation. Scores on the Geriatric Depression Scale (15 items) and demographic variables were collected during face-to-face interviews. The activities of daily living were assessed using the Katz Index based on nurses' observation, and medical diagnoses were obtained from the patient records. Pearson's chi-square test and ordinal logistic regression were used to identify possible associations between activities of daily living and depression. After adjustment for age, sex, marital status, length of stay per year and education, more dependence on activities of daily living was associated with depression [odds ratio (OR): 1·18; 95% confidence interval (CI): 1·04-1·37; p = 0·02]. Higher age was associated with less depression (OR: 0·64; 95% CI: 0·43-0·94; p = 0·02), that is, the odds of depression declined by 36% for each 10-year increase in age. Our results suggest that depression symptoms are a major health problem among nursing home residents without cognitive impairment and that younger residents are more prone to having depressive symptoms. Nursing home staff should communicate with and observe residents closely for signs of depression, especially younger residents with high dependence on activities of daily living

    HepG2 cells biospecific extraction method and high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) analysis was proposed for screening of potential antiatherosclerotic active components in Bupeuri radix, a well-known Traditional Chinese Medicine (TCM). The hypothesis suggested that when cells are incubated together with the extracts of TCM, the potential bioactive components in the TCM should selectively combine with the receptor or channel of HepG2 cells, then the eluate which contained biospecific component binding to HepG2 cells was identified using HPLC-ESI-MS analysis. The potential bioactive components of Bupeuri radix were investigated using the proposed approach. Five compounds in the saikosaponins of Bupeuri radix were detected as these components selectively combined with HepG2 cells, among these compounds, two potentially bioactive compounds namely saikosaponin b1 and saikosaponin b2 (SSb2) were identified by comparing with the chromatography of the standard sample and analysis of the structural clearance characterization of MS. Then SSb2 was used to assess the uptake of DiI-high density lipoprotein (HDL) in HepG2 cells for antiatherosclerotic activity. The results have showed that SSb2, with indicated concentrations (5, 15, 25, and 40 μM) could remarkably uptake dioctadecylindocarbocyanine labeled- (DiI) -HDL in HepG2 cells (Vs control group, *PESI-MS analysis is a rapid, convenient, and reliable method for screening potential bioactive components in TCM and SSb2 may be a valuable novel drug agent for the treatment of atherosclerosis.

    The integration of primary care and public health nursing may provide new opportunities for transforming nursing practice that addresses population health. Effective programs emphasize multilevel approaches that include both downstream (education) and upstream (policy change) actions. The purpose of this article is to identify downstream and upstream nursing actions that integrate public health and primary care practice through two case exemplars concerning disparities in physical activity and nutrition. Describe two research case exemplars: (1) a secondary analysis of school physical activity policy for female adolescents in 36 public middle schools and (2) a focus group study of African American adults in a community kitchen program. In exemplar 1, school policies lacked population-based standards and presented structural disadvantages to African American girls who were already obese. In exemplar 2, participants found the community kitchen program to be more effective than the federally funded nutrition program. Integrating primary care and public health nursing could improve the tailoring of physical activity and nutrition programs to local populations by following core principles of community engagement, infrastructural sustainability, aligned leadership, and data sharing for population health improvement. © 2017 Wiley Periodicals, Inc.

    Microalgae represent a rich source that satisfies the growing need for novel ingredients of nutriceuticals, pharmaceuticals, and food supplements. Haematococcus pluvialis and Dunaliella salina microalgae are isolated from the Egyptian hydro-flora and are reported for their potent antioxidant activities. The cytotoxic activity of different fractions of both microalgae was investigated on 4 cell lines HePG2, MCF7, HCT116, and A549. The carotenoid rich fraction of H. pluvialis showed potent cytotoxic activity against colon cancer cell line and moderate activity against both liver and breast cancer cell lines. On the other hand, the carotenoid rich fraction of D. salina showed mild cytotoxic activity on breast and liver cancer cell lines. The carotenoid rich fraction of H. pluvialis was analysed using LC-DAD/ESI-MS and the major carotenoids were identified either free as well as bounded to fatty acids.

    Individuals living with mental health disorders served by the public mental health system often face comorbid medical conditions that affect their quality of life and lifespan. The effect of physical limitations on the engagement in daily activities among individuals living with mental health disorders has not been extensively researched. Adults attending community wellness centers (N = 53) in a northeastern United State were included in a descriptive study exploring the impact of physical limitations on daily activities. The activities most frequently affected were: walking or moving around, sleeping, and finding a job. The physical limitations affecting these three activities were lack of energy and pain. Health care professionals, including mental health nurses and occupational therapy practitioners, are in an ideal position to collaborate by evaluating and offering treatment interventions that address physical limitations to positively affect occupational functioning and recovery.

    The majority of nursing students are kinesthetic learners, preferring a hands-on, active approach to education. Research shows that active-learning strategies can increase student learning and satisfaction. This study looks at the use of one active-learning strategy, a Jeopardy-style game, 'Nursopardy', to reinforce Fundamentals of Nursing material, aiding in students' preparation for a standardized final exam. The game was created keeping students varied learning styles and the NCLEX blueprint in mind. The blueprint was used to create 5 categories, with 26 total questions. Student survey results, using a five-point Likert scale showed that they did find this learning method enjoyable and beneficial to learning. More research is recommended regarding learning outcomes, when using active-learning strategies, such as games. Copyright © 2012 Elsevier Ltd. All rights reserved.

    AMP-regulated protein kinase (AMPK) is involved in regulation of energy-generating pathways in response to the metabolic needs in different organs including the heart. The activity of AMPK is mainly controlled by AMP concentration that in turn could be affected by nucleotide metabolic pathways. This study aimed to develop a procedure for measurement of AMPK activity together with nucleotide metabolic enzymes and its application for studies of mice treated with high-fat diet. The method developed was based on analysis of conversion of AMARA peptide to pAMARA by partially purified heart homogenate by liquid chromatography/mass spectrometry (LC/MS). Activities of the enzymes of nucleotide metabolism were evaluated by analysis of conversion of substrates into products by HPLC. The method was applied for analysis of hearts of mice fed 12 weeks with low- (LFD) or high-fat diet (HFD). The optimized method for AMPK activity analysis (measured in presence of AMP) revealed change of activity from 0.089 ± 0.035 pmol/min/mg protein in LFD to 0.024 ± 0.002 in HFD. This coincided with increase of adenosine deaminase (ADA) activity from 0.11 ± 0.02 to 0.19 ± 0.06 nmol/mg tissue/min and decrease of AMP-deaminase (AMPD) activity from 1.26 ± 0.35 to 0.56 ± 0.15 nmol/mg tissue/min for LFD and HFD, respectively. We have proven quality of our LC/MS method for analysis of AMPK activity. We observed decrease in AMPK activity in the heart of mice treated with high-fat diet. However, physiological consequences of this change could be modulated by decrease in AMPD activity.

    In recent years, much effort has been invested all over the world in nurse recruitment and retention. Issues arising in this context are low job satisfaction, the poor public image of nursing and the reluctance of nurses to promote or market their profession. This study aimed to examine factors explaining the marketing of the nursing profession by nurses working at a general tertiary medical centre in Israel. One hundred sixty-nine registered nurses and midwives from five clinical care units completed a structured self-administered questionnaire, measuring (a) professional self-image, (b) job satisfaction, (c) nursing promotional and marketing activity questionnaire, and (d) demographic data. The mean scores for the promotion of nursing were low. Nurses working in an intensive cardiac care unit demonstrated higher levels of promotional behaviour than nurses from other nursing wards in our study. Nurse managers reported higher levels of nursing promotion activity compared with first-line staff nurses. There was a strong significant correlation between job satisfaction and marketing behaviour. Multiple regression analysis shows that 15% of the variance of promoting the nursing profession was explained by job satisfaction and job position. Nurses are not inclined to promote or market their profession to the public or to other professions. The policy on the marketing of nursing is inadequate. A three-level (individual, organizational and national) nursing marketing programme is proposed for implementation by nurse leadership and policy makers. Among proposed steps to improve marketing of the nursing profession are promotion of the image of nursing by the individual nurse in the course of her or his daily activities, formulation and implementation of policies and programmes to promote the image of nursing at the organizational level and drawing up of a long-term programme for promoting or marketing the professional status of nursing at the national level. © 2015

    Full Text Available Background: Improving the quality of health care is central to the proposed health care reforms in South Africa. Nursing unit managers play a key role in coordinating patient care activities and in ensuring quality care in hospitals. Objective: This paper examines whether the activities of nursing unit managers facilitate the provision of quality patient care in South African hospitals. Methods: During 2011, a cross-sectional, descriptive study was conducted in nine randomly selected hospitals (six public, three private in two South African provinces. In each hospital, one of each of the medical, surgical, paediatric, and maternity units was selected (n=36. Following informed consent, each unit manager was observed for a period of 2 hours on the survey day and the activities recorded on a minute-by-minute basis. The activities were entered into Microsoft Excel, coded into categories, and analysed according to the time spent on activities in each category. The observation data were complemented by semi-structured interviews with the unit managers who were asked to recall their activities on the day preceding the interview. The interviews were analysed using thematic content analysis. Results: The study found that nursing unit managers spent 25.8% of their time on direct patient care, 16% on hospital administration, 14% on patient administration, 3.6% on education, 13.4% on support and communication, 3.9% on managing stock and equipment, 11.5% on staff management, and 11.8% on miscellaneous activities. There were also numerous interruptions and distractions. The semi-structured interviews revealed concordance between unit managers’ recall of the time spent on patient care, but a marked inflation of their perceived time spent on hospital administration. Conclusion: The creation of an enabling practice environment, supportive executive management, and continuing professional development are needed to enable nursing managers to lead the provision

    Hibiscus sabdariffa has gained attention for its antioxidant activity. There are many accessions of H. sabdariffa in the world. However, information on the quantification of antioxidant compounds in different accessions is rather limited. In this paper, a liquid chromatography/quadrupole-time-of-flight mass spectrometry (LC-Q-TOF-MS) method for simultaneous determination of five antioxidant compounds (neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutin, and isoquercitrin) in H. sabdariffa leaves was developed. The method was validated for linearity, sensitivity, precision, repeatability and accuracy. The validated method has been successfully applied for determination of the five analytes in eight accessions of H. sabdariffa. The eight accessions of H. sabdariffa were evaluated for their antioxidant activities by DPPH free radical scavenging assay. The investigated accessions of H. sabdariffa were rich in rutin and exhibited strong antioxidant activity. The two accessions showing the highest antioxidant activities were from Cuba (No. 2) and Taiwan (No. 5). The results indicated that H. sabdariffa leaves could be considered as a potential antioxidant source for the food industry. The developed LC-Q-TOF-MS method is helpful for quality control of H. sabdariffa.

    Shift work have been thought to restrict participation in leisure time activities, but the knowledge about physical activity in rotating night shift nurses has been limited so far. We investigated the associations between the rotating night shift work and physical activity using data from a cross-sectional study among nurses and midwives. This study included 354 nurses and midwives (aged 40-60) currently working rotating night shifts and 371 ones working days only. The information on the work characteristics and potential covariates was collected via a personal interview. Weight and height were measured and BMI was calculated. Physical activity was assessed according to the international questionnaire on physical activity - IPAQ, and four domains: leisure time, occupational, transport related and household were analyzed. Women who reported none leisure time activity were defined as recreationally "inactive". The associations were examined with multiple linear or logistic regression models adjusted for age, season of the year, number of full term births, marital status and BMI. Total and occupational physical activity was significantly higher among nurses working rotating night shifts. However, leisure time activity was significantly affected among rotating night shift nurses and midwives, compared to women working during the days only, with increased odds ratio for recreational "inactivity" (OR = 1.57, 95% CI: 1.11-2.20). Rotating night shift work among nurses and midwives is associated with higher occupational physical activity but lower leisure time activity. Initiatives supporting exercising among night shift workers are recommended.

    In this study, the aroma-active compounds in the dried flower of Malva sylvestris L. were extracted by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS), and gas chromatography-olfactometry (GC-O) and aroma extraction dilution analysis (AEDA). A light yellow oil with a sweet odor was obtained with a percentage yield of 0.039% (w/w), and 143 volatile compounds (89.86%) were identified by GC-MS. The main compounds were hexadecanoic acid (10.1%), pentacosane (4.8%) and 6,10,14-trimethyl-2-pentadecanone (4.1%). The essential oil consisted mainly of hydrocarbons (25.40%) followed by, alcohols (18.78%), acids (16.66%), ethers (5.01%) ketones (7.28%), esters(12.43%), aldehydes (2.30%) and others (2.00%). Of these compounds, 20 were determined by GC-O and AEDA, to be odor-active (FD (flavor dilution) factor ≥ 1). β-Damascenone (FD = 9, sweet), phenylacetaldehyde (FD = 8, floral, honey-like) and (E)-β-ocimene (FD = 8, spicy) were the most intense aroma-active compounds in M. sylvestris. In order to determine the relative contribution of each of the compounds to the aroma of M. sylvestris, odor activity values (OAVs) were used. β-Damascenone had the highest odor activity values (OAV) (50,700), followed by (E)-β-ionone (15,444) and decanal (3,510). In particular, β-damascenone had a high FD factors, and therefore, this compound was considered to be the main aroma-active components of the essential oil. On the basis of AEDA, OAVs, and sensory evaluation results, β-damascenone is estimated to be the main aroma-active compound of the essential oil.

    Oily fraction was extracted from the water hyacinth (Eichhornia crassipes) using n-hexane by both cold and hot extraction in 5.5 ± 0.05% and 9.30 ± 0.05%, respectively, however, no difference was found in the nature of the compounds extracted by the two processes. The analysis of this oil was carried out using GC-FID and GC-MS in separate experiments and the nature of the compounds was investigated by library matching of the spectra obtained through GC-MS. This extract was found to contain 33.267% of the nonadecan-4-ol and 20.51% of a long chain ketone in addition to various quantities of the long chain nitrogenous compounds. The antibacterial activity of the extract was investigated against eight pathogenic bacteria and fungus Candida albican using disc diffusion method. The extract was found to be highly active against all tested bacterial strains except S. typhi. For most of the strains the activity of the extract was near the reference. Ciprofloxacin, clotrimazole and erythromycin were used as reference antibiotics. (author)

    By merging a high-performance liquid chromatography diode array detector (HPLC-DAD) method with high-performance thin-layer chromatography (HPTLC), an assay was developed for chemical fingerprinting and quantitative analysis of traditional medicine Majun Mupakhi ELA (MME), and constituent compounds were identified using HPLC coupled with UHPLC-DAD-Quadrupole-Orbitrap-MS method. In addition, the antioxidant capacity of MME was assessed based on the ability of components to scavenge radicals using in vitro method. Using a HPLC-DAD method with HPTLC easily validated the chemical fingerprinting results and quantified three characteristic components, namely, gallic acid (1), daidzein (2), and icariin (3), in commercial MMEs. The three compounds presented excellent regression values ( R 2 = 0.9999) in the ranges of the test and the method recovery was in the range from 100.49% to 100.68%. The fingerprints had 27 common characteristic peaks, of which 13 were verified by rapid UHPLC-DAD-Q-Orbitrap-MS analysis. In vitro antioxidant assays rapidly assessed and contrasted antioxidant activity or the free radical scavenging activity of the main polyphenolic classes in MMEs, and the antioxidant capacity was mostly affected by the presence of gallic acid. Thus, this study establishes a powerful and meaningful approach for MME quality control and for assessing in vitro antioxidant activity.

    Development of insect resistance to synthetic pesticides, high operational cost and environmental pollution have created the need for developing alternative approaches to control vector-borne diseases. In the present study, larvicidal activity of flavonoid extracts of different parts of Vitex negundo (Linnaeus) and Andrographis paniculata (Nees) have been studied against the late III or early IV instar larvae of Aedes aegypti and Anopheles stephensi (Liston). Flavonoids were extracted from different parts of the selected plants using standard method. Bioassay test was carried out by WHO method for determination of larvicidal activity against mosquitoes. Different compounds of the most active extract were identified by the gas chromatography-mass spectrometry (GC-MS) analysis. Flavonoid extract of whole aerial part of A. paniculata was found to be inactive against the selected larvae of Ae. aegypti even at the concentration of 600 ppm, whereas it caused 70% mortality in An. stephensi at the concentration of 200 ppm. Flavonoid extract of flower-buds produced highest mortality (100%) at the concentration of 600 ppm for the late III or early IV instar larvae of Ae. aegypti and at the concentration of 200 ppm for the larvae of An. stephensi. GC-MS analysis of the most active flavonoid extract from flower-buds of Vitex showed 81 peaks. Phenol (26.83% area), naphthalene (4.95% area), 2,3-dihydrobenzofuran (6.79% area), Phenol-2,4-Bis (1,1-dimethyl) (4.49% area), flavones 4'-OH,5-OH,7-di-O-glucoside (0.25% area) and 5-hydroxy- 3,6,7,3',4'-pentamethoxy flavones (0.80% area) were present in major amount. Flavonoid extracts from different parts of two selected plants possess larvicidal activity against two selected mosquito species, hence, could be utilized for developing flavonoid-based, eco-friendly insecticide as an alternative to synthetic insecticides.

    In 2007 and 2008, 115 patients were found to be either certainly or presumptively infected with the hepatitis C virus through the reuse of contaminated medication vials at two southern Nevada endoscopy clinics. A subsequent joint investigation by federal and state agencies found multiple breaches of infection control protocols. There was also strong anecdotal evidence that among clinic staff, unsafe patient care conditions often went unreported because of a general fear of retaliation. At the request of the Nevada legislature's Legislative Committee on Health Care, a study was conducted to examine Nevada RNs' experiences with workplace attitudes toward patient advocacy activities. This article presents the study findings and reviews how one public health tragedy led to the creation of effective health care policy. A study questionnaire was developed and tested for reliability and validity. Questionnaires were then sent to an initial sample of 1,725 Nevada RNs, representing 10% of all RNs in the Nevada State Board of Nursing database with active licenses and current Nevada addresses. The response rate was modest at 33% (564 respondents). Of those who responded, 34% indicated that they'd been aware of a patient care condition that could have caused harm to a patient, yet hadn't reported it. The most common reasons given for nonreporting included fears of workplace retaliation (44%) and a belief that nothing would come of reports that were made (38%). The study findings underscore the need for a shift in organizational culture toward one that encourages clear and open communication when patient safety may be in jeopardy. These findings were ultimately used to support the passage of whistleblower protection legislation in Nevada. Las Vegas hepatitis C outbreak, patient advocacy, whistleblower.

    The life expectancy of adults with mental illness is significantly less than that of the general population, and this is largely due to poor physical health. Behavioural counselling can improve physical health indicators among people with non-communicable disease. This repeated-measures, single-group intervention trial evaluated the effects of a 19-week behavioural counselling programme on metabolic health indicators and physical activity levels of outpatient adults with mental illness. Sixteen participants completed the intervention that comprised individual face-to-face counselling sessions with a registered nurse every 3 weeks, and progress reviews with a medical practitioner every 6 weeks. Assessment included self-report and objective measurement of physical activity, and measures of blood pressure and anthropometry. Statistically-significant changes were demonstrated between baseline and post intervention for participants' waist circumference (P = 0.035) and waist-to-height ratio (P = 0.037). Non-significant improvements were demonstrated in weight and physical activity. The findings indicated that adults with mental illness can engage in a nurse-led behavioural counselling intervention, with improvements in some metabolic health measures after 19 weeks. It is recommended that behavioural counselling programmes for adults with mental illness be sustained over time and have an 'open door' policy to allow for attendance interruptions, such as hospitalization. © 2017 Australian College of Mental Health Nurses Inc.

  11. Copper-induced activation of TRP channels promotes extracellular calcium entry and activation of CaMs and CDPKs leading to copper entry and membrane depolarization in Ulva compressa

    Full Text Available In order to identify channels involved in membrane depolarization, Ulva compressa was incubated with agonists of TRP channels C5, A1 and V1 and the level of intracellular calcium was detected. Agonists of TRPC5, A1 and V1 induced increases in intracellular calcium at 4, 9 and 12 min of exposure, respectively, and antagonists of TRPC5, A1 and V1 corresponding to SKF-96365 (SKF, HC-030031 (HC and capsazepin (CPZ, respectively, inhibited calcium increases indicating that functional TRPs exist in U. compressa. In addition, copper excess induced increases in intracellular calcium at 4, 9 and 12 min which were inhibited by SKF, HC and CPZ, respectively, indicating that copper activate TRPC5, A1 and V1 channels. Moreover, copper-induced calcium increases were inhibited by EGTA, a non-permeable calcium chelating agent, but not by thapsigargin, an inhibitor of endoplasmic reticulum (ER calcium ATPase, indicating that activation of TRPs leads to extracellular calcium entry. Furthermore, copper-induced calcium increases were not inhibited by W-7, an inhibitor of CaMs, and staurosporine, an inhibitor of CDPKs, indicating that extracellular calcium entry did not require CaMs and CDPKs activation. In addition, copper induced membrane depolarization events at 4, 8 and 11 min and these events were inhibited by SKF, HC, CPZ and bathocuproine, a specific copper chelating agent, indicating copper entry through TRP channels leading to membrane depolarization. Moreover, membrane depolarization events were inhibited by W-7 and staurosporine, indicating that CaMs and CDPKs are required in order to activate TRPs to allow copper entry. Thus, light-dependent copper-induced activation TRPC5, A1 and V1 promotes extracellular calcium entry leading to activation of CaMs and CDPKs which, in turn, promotes copper entry through these TRP channels leading to membrane depolarization.

    To investigate health differences between nurses who report meeting the daily physical activity recommendations in or away from the workplace. Adhering to the national physical activity recommendations has known health benefits. Whilst often considered a workplace active profession, data are emerging of poor health amongst nurses. However, health differences between workplace or leisure-time physically active nurses are understudied. The investigation is an observation study of Australian and New Zealand nurses. Data were generated from the longitudinal, population-based, observational e-Cohort nursing survey. Data were informed and groups defined by the self-reported minutes per day of moderate physical activity collected from a large international survey of practicing nurses (n = 2264). Groups were: Group (G) 1--high workplace (≥30 minutes/day)/high leisure (≥30 minutes/day), G2--high workplace/low leisure (workplace/low leisure (workplace/high leisure. G2 had a high BMI and were younger than G4. G4 were significantly more active away from work and more likely to report cycling to work than G2. In contrast, G2 were most likely to have taken sick days because of their health (χ(2) = 19·101), have difficulty sleeping most of the time and have a medical history of diagnosed anxiety and depression. This study shows that improved well-being can be achieved in nursing cohort through leisure-time physical activity. This research shows that nurse should consider leisure-time physical activity necessary to maintain and prolong health and that workplace activity is not a sufficient stimulus. This has important implications for workforce planners and administrators. © 2012 Blackwell Publishing Ltd.

    Soyasaponins are oleanene-type triterpenoid saponins, naturally occurring in many edible plants that have attracted a great deal of attention for their role in preventing chronic diseases. The aim of this study was to establish the distribution and the content of soyasaponins in 21 ecotypes of Fagioli di Sarconi beans (Phaseolus vulgaris, Leguminosae). High-performance reversed-phase liquid chromatography (RPLC) with positive electrospray ionization (ESI(+)) and Fourier transform ion cyclotron resonance (FTICR) mass spectrometry (MS) in conjunction with infrared multiphoton dissociation (IRMPD) was applied for the unambiguous identification of soyasaponins Ba (m/z 959.5213, [C 48 H 79 O 19 ] + ), Bb (m/z 943.5273, [C 48 H 79 O 18 ] + ), Bd (m/z 957.5122, [C 48 H 77 O 19 ] + ), and Be (m/z 941.5166, [C 48 H 77 O 18 ] + ), which are the only commercially available reference standards. In addition, the several diagnostic product ions generated by IRMPD in the ICR-MS cell allowed us the putative identification of soyasaponins Bb' (m/z 797.4680, [C 42 H 69 O 14 ] + ), αg (m/z 1085.5544, [C 54 H 85 O 22 ] + ), βg (m/z 1069.5600, [C 54 H 85 O 21 ] + ), and γg (m/z 923.5009, [C 48 H 75 O 17 ] + ), establishing thus their membership in the soyasaponin group. Quantitative and semiquantitative analysis of identified soyasaponins were also performed by RPLC-ESI(+) FTICR-MS; the total concentration levels were found ranging from 83.6 ± 9.3 to 767 ± 37 mg/kg. In vitro hypoglycemic outcomes of four soyasaponin standards were evaluated; significant inhibitory activities were obtained with IC 50 values ranging from 1.5 ± 0.1 to 2.3 ± 0.2 μg/mL and 12.0 ± 1.1 to 29.4 ± 1.4 μg/mL for α-glucosidase and α-amylase, respectively. This study represents the first detailed investigation on the antidiabetic activity of bioactive constituents found in Fagioli di Sarconi beans.

    Nursing facility patients are a population that has not been well studied with regard to functional status and independence previously. As such, the manner in which activities of daily living (ADL) relate to one another is not well understood in this population. An understanding of ADL difficulty ordering has helped to devise systems of functional independence grading in other populations, which have value in understanding patients' global levels of independence and providing expectations regarding changes in function. This study seeks to examine the hierarchy of ADL in the nursing facility population. Data were analyzed from the 2004 National Nursing Home Survey, a cross-sectional data set of 13 507 skilled nursing facility subjects with functional independence items. The ADL difficulty hierarchy was determined using Rasch analysis. Item fit values for the Rasch model using Mean-Square infit statistics were also determined. The robustness of the hierarchy was tested for each ADL. Two grading systems were devised from the results of the item difficulty ordering. One was based on the most difficult item that he or she could perform, and the other assigned a grade based on the least difficult item that a subject could not perform. A total of 13 113 patients were included in this analysis, the majority of whom were female and white. They had an average age of 81 years. An ordered hierarchy of ADL was found with eating being the easiest and bathing the most difficult. All items in the Katz index fit the Rasch model adequately well. The majority of patients able to perform any particular ADL were also able to perform all easier ADL. Cohen's κ for the 2 grading systems was 0.73. This study is the first to show the expected hierarchy of difficulty of the 6 activities of daily proposed in the Katz index in the nursing facility population. The hierarchy found in this population matches the original hierarchy found in older adults in the community and acute care settings

    After The Great East Japan Earthquake in March 2011, the great disaster not only was a seismic hazard but also influenced health anxiety by the radiation in the nuclear power plant. The residents who lived in this area have been faced with strict dangerous circumstances still now. So this research is to clarify the substance of supporting activities of the public health nurses of a local government after a nuclear power plant disaster. Group interviews were conducted with public health nurses who were engaged in Fukushima nuclear power plant disaster experiences. The numbers of the public health nurses were 11 (3 belonged to prefecture governments, 8 belonged to local governments). Their mean tenure as a public health nurse was 30.7±3.0 years. They didn't have any training opportunity to get technical knowledge of the nuclear power plant disaster, so that they couldn't cope with the anxiety of the residents after the disaster. Therefore, it is necessary to improve 'the fundamental knowledge of radiation', 'a care of the heart', 'risk communication', 'organizations-concerned cooperation' and 'organization maintenance at the time of usual circumstances'. We found that the local governments which have a nuclear power plant institution have not been trained enough at the time of usual business, nor maintenance of operations required for accident preparedness, either. It was showed that from now on, the education for public health nurses is emergently required to cope with a radiation disaster, including a fundamental knowledge of radiation and resident support services from local governments regardless of whether their prefecture has a nuclear power plant or not.

    There is increasing emphasis on person-centred care within the literature and the health care context. It is suggested that a person-centred approach to medication activities has the potential to improve patient experiences and outcomes. This study set out to examine how nurses and patients interact with each other during medication activities in an acute care environment with an underlying philosophy of person-centred care. A qualitative approach was used comprising naturalistic observation and semi-structured interviews. The study setting was an acute care ward with a collaboratively developed philosophy of person-centre care, in an Australian metropolitan hospital. Eleven nurses of varying levels of experience were recruited to participate in observations and interviews. Nurses were eligible to participate if they were employed on the study ward in a role that incorporated direct patient care, including medication activities. A stratified sampling technique ensured that nurses with a range of years of clinical experience were represented. Patients who were being cared for by participating nurses during the observation period were recruited to participate unless they met the following exclusion criteria: those less than 18 years of age, non-English speaking patients, and those who were unable to give informed consent. Twenty-five patients were observed and 16 of those agreed to be interviewed. The results of the study generated insights into the nature of interactions between nurses and patients where person-centred care is the underlying philosophy of care. Three major themes emerged from the findings: provision of individualised care, patient participation and contextual barriers to providing person-centred care. While the participating nurses valued a person-centred approach and perceived that they were conducting medication activities in a person-centred way, some nurse-patient interactions during medication activities were centred on routines rather than

    The structures of the condensed tannins from leaf, stem bark and root bark of Acacia confusa were characterized by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis, and their antioxidant activities were measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and ferric reducing/antioxidant power (FRAP) assays. The results showed that the condensed tannins from stem bark and root bark include propelargonidin and procyanidin, and the leaf condensed tannins include propelargonidin, procyanidin and prodelphinidin, all with the procyanidin dominating. The condensed tannins had different polymer chain lengths, varying from trimers to undecamers for leaf and root bark and to dodecamers for stem bark. The condensed tannins extracted from the leaf, stem bark and root bark all showed a very good DPPH radical scavenging activity and ferric reducing power.

    Intensive care units (ICUs) are traditionally settings that offer high technologically advanced treatment for those who are in critical situations due to an illness or accident. Questions regarding the withdrawal and withholding as well as the ending of life sustaining treatment are related to ethical dilemmas. Nurses’ decision-making processes and nursing activities in different countries are scarcely studied. Which end-of-life decision-making processes and activities that are performed by nurses can be identified and described? The objective is the identification of a nursing terrain regarding decision-making and activities in patient end-of-life care on the intensive care unit. Semi-structured interviews were conducted with 51 experienced nurses in university or hospital premises: 10 in Brazil, 9 in England, 10 in Germany, 10 in Ireland and 12 nurses in Palestine. The study used grounded theory to inform data collection and analysis. The finding of the study is the identification of a dynamic process in which activities with a focus on cure shift to activities with a focus on end-of-life care. The core category that emerged was ’negotiated reorienting’: The shift of activities implies negotiations between nurses and physicians, relatives as well as with oneself. Moreover the process is characterized by a constant re-orientation that is induced by changing patient data and the realisation of the whole situation. Nurses’ core practices are ’consensus seeking’ and ’emotional holding’ (sub-categories). In all countries a nursing terrain of activities in end-of-life care could be identified and described. However, it is unclear whether nursing activities connected to relatives of the patient are dominant in such a way that relations to dying patients and respect for their autonomy are put into the background. A field study could give answers to this question possible.

Finally, nine compounds, which could combine with macrophages, in an ethanol extract of AH were detected by comparing basic peak intensity (BPI profiles of macrophages before and after treatment with AH. Then they were identified as Andrographidine E (1, Andrographidine D (2, Neoandrographolide (3, Dehydroandrographolide (4, 5, 7, 2′, 3′-tetramethoxyflavone (5, β-sitosterol (7, 5-hydroxy-7, 2′, 3′-trimethoxyflavone (8 and 5-hydroxy-7, 8, 2′, 3′-tetramethoxyflavone (9, which could classified into five flavonoids, three diterpene lactones, and one sterol. Their structures were recognized by their characteristic fragment ions and fragmentations pattern of diterpene lactones and flavonoids. Additionally, the activity of compounds 3, 4, and 7 was tested in vitro. Results showed that these three compounds could decrease the release of NO (p < 0.01 in macrophages remarkably. Moreover, 3, 4, and 7 showed satisfactory dose-effect relationships and their IC50 values were 9.03, 18.18, and 13.76 μg/mL, respectively. This study is the first reported work on the screening of immunological active components from AH. The potential immunological activity of flavonoids from AH has not been reported previously.

    Curcumol has recently attracted special attention due to its potential activities in many chronic disorders. Moreover, the traditional role of turmeric [Curcuma longa L. (Zingiberaceae)] in suppression of hyperglycemia is of great interest. The present work explores the potential acute and subchronic antihyperglycemic, antinociceptive, and in vivo antioxidant effects of curcumol in alloxan-diabetic mice. Bio-guided fractionation, column-chromatography, and GC-MS were utilized to identify the most active compound of turmeric (curcumol). Turmeric (25, 50, and 100 mg/kg), the curcumol rich fraction (CRF) (7 mg/kg), and curcumol (20, 30, and 40 mg/kg) were assessed for their acute (6 h) and subchronic (8 d) antihyperglycemic potentials and antinociceptive effects (8 weeks) were measured, using hot-plate and tail-flick latencies and von-Frey filaments method and in vivo antioxidant effects in alloxan-diabetic mice. The most-active turmeric fraction was found to be rich in curcumol (45.5%) using GC-MS analysis method. The results proved that the highest dose levels of turmeric extract and curcumol exerted remarkable hypoglycemic activity with 41.4 and 39.3% drop in the mice glucose levels after 6 h, respectively. Curcumol (40 mg/kg) was found to be 9.4% more potent than turmeric extract (100 mg/kg) in subchronic management of diabetes. Curcumol also showed a significant improvement of peripheral nerve function as observed from the latency and tactile tests. The antioxidant potential of curcumol may cause its ability to ameliorate diabetes and diabetes-related complications. Curcumol, a natural metabolite with a good safety-profile, showed results comparable with tramadol in reversing diabetes-induced tactile allodynia and hyperalgesia.

    Full Text Available Objectives: To estimate the prevalence of metabolic syndrome (MS in female nurses in the Hospital Juan A. Fernandez (HJAF, Buenos Aires, Argentina, and to determine whether work, rest, diet, and health, are predictive of it.Materials and methods: For the first objective, a descriptive, observational and cross-sectional study was conducted, and for the second, a multivariate cross-sectional observational multivariate analysis was made comparing independent samples. A total of 192 nurses were studied between October 2008 and March 2009. They completed a questionnaire that include indicators that could be predictors of MS. Anthropometric measurements, including blood pressure were taken, was well as a blood sample to analyze fasting glucose, HDL-C and plasma triglycerides.Results: It was found that 35% and 41% of nurses were overweight and obese, respectively. A total of 92% had centro-abdominal obesity. The prevalence of MS found was 33.3% (95%CI, 26.7 to 40.5. Those who had this disease were between 53±9 years. Statistically significant differences were found in the bivariate analysis between MS and the variables, age, length of service, time worked during night shift, and academic studies.Conclusions: The prevalence of MS was 64/192 in HJAF nurses (33.3% I 95%CI, 26.7-40.5. There were no statistically significant differences with the indicators of, age, “time worked during night shift”, and “studies”. These results suggest that age is the most important variable in predicting the onset of MS in the population of nurses.

    Full Text Available For decades, Hibiscus sabdariffa L. and its phytochemicals have been shown to possess a wide range of pharmacologic properties. In this study, aqueous extract of Hibiscus sabdariffa (AEHS and its bioactive constituent protocatechuic acid (PCA, have been evaluated in vitro for their antiviral activity against HSV-2 clinical isolates and anti-enzymatic activity against urease. Antiherpetic activity was evaluated by the titer reduction assay in infected Vero cells, and cytotoxicity was evaluated by the neutral red dye-uptake method. Anti-urease activity was determined by a developed Electrospray Ionization-Mass Spectrometry (ESI-MS-based assay. PCA showed potent anti-HSV-2 activity compared with that of acyclovir, with EC50 values of 0.92 and 1.43 µg∙mL−1, respectively, and selectivity indices > 217 and > 140, respectively. For the first time, AEHS was shown to exert anti-urease inhibition activity, with an IC50 value of 82.4 µg∙mL−1. This, combined with its safety, could facilitate its use in practical applications as a natural urease inhibitor. Our results present Hibiscus sabdariffa L. and its bioactive compound PCA as potential therapeutic agents in the treatment of HSV-2 infection and the treatment of diseases caused by urease-producing bacteria.

    Critical thinking in Health Sciences is among the transversal competences in the Nursing Degree. The critical card is a tool of individual learning, designed to develop critical thinking, and set in the process of environmental health learning. Every student must perform the activity to obtain the highest qualification in Community Health Nursing subject. The aim of this project was to evaluate this learning tool using the students' perceptions after its performance. The evaluation was based on the answers to a questionnaire obtained from the third course students of Nursing Degree at the University of Zaragoza. The questionnaire was made up of 14 Likert-type questions, grouped in four dimensions. The student participation rate was higher than 50%. The analysis of the questionnaire obtained 67,8% positive answers. The variability between dimensions ranged between 49% of positive answers for application in other subjects and 87% of positive answers for the improvements applicable to the instrument. The students coincided in indicating that the critical card is a useful learning tool and could be applicable in other subjects. However, the weight it is given in the global evaluation of the subject is considered to be too low, considering the time used to complete the activity. Copyright © 2017 Elsevier Ltd.

    This study aimed not only to describe the development and implementation of the module but also to evaluate the nursing students' perceptions. A cross-sectional design including 101 students who were asked to participate and answer a survey. We describe the development of the pedagogic module Students Active Learning via Internet Observations based on situated learning. The findings show that learning about service users' own lived experiences via web-based platforms was instructive according to the students: 81% agreed to a high or very high degree. Another important finding was that 96% of students responded that the module had clinical relevance for nursing work. We argue that learning that engages students with data that are contextually and culturally situated is important for developing competence in caregiving. © 2015 Wiley Periodicals, Inc.

    Liver disease is a worldwide problem. It represents one of the main causes of morbidity and mortality in humans. Achillea biebersteinii is used as herbal remedy for various ailments including liver diseases. But the scientific basis for its medicinal use remains unknown. Thus, this research was undertaken to evaluate the efficiency of A. biebersteinii essential oil (ABEO) (0.2 mL/kg) in the amelioration of CCl4-induced hepatotoxicity in rodent model. Moreover, the chemical content of the oil was investigated using GC and GC-MS. The following biochemical parameters were evaluated: serum glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), gamma-glutamyl-transpeptidase (γ-GGT), alkaline phosphatase (ALP), and total bilirubin. Furthermore, lipid profile, malondialdehyde (MDA), nonprotein sulfhydryl (NP-SH), and total protein (TP) contents in liver tissue were estimated. 44 components (92.0%) of the total oil have been identified by GC-MS analysis where α-terpinene and p-cymene were the most abundant. The high serum enzymatic (GOT, GPT, GGT, and ALP) and bilirubin concentrations as well as the level of MDA, NP-SH, and TP contents in liver tissues were significantly reinstated towards normalization by the ABEO. Histopathological study further confirmed these findings. In addition, ABEO showed mild antioxidant activity in 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and β-carotene-linoleic acid assays.

    Full Text Available Variation of metabolic profiles in Cordyceps pruinosa mycelia cultivated under various media and light conditions was investigated using 1H nuclear magnetic resonance (NMR analysis and gas chromatography mass spectrometry (GC-MS with multivariate statistical analysis. A total of 71 metabolites were identified (5 alcohols, 21 amino acids, 15 organic acids, 4 purines, 3 pyrimidines, 7 sugars, 11 fatty acids, and 5 other metabolites by NMR and GC-MS analysis. The mycelia grown in nitrogen media and under dark conditions showed the lowest growth and ergosterol levels, essential to a functional fungal cell membrane; these mycelia, however, had the highest levels of putrescine, which is involved in abiotic stress tolerance. In contrast, mycelia cultivated in sabouraud dextrose agar with yeast extract (SDAY media and under light conditions contained relatively higher levels of fatty acids, including valeric acid, stearic acid, lignoceric acid, myristic acid, oleic acid, palmitoleic acid, hepadecenoic acid, and linoleic acid. These mycelia also had the highest phenolic content and antioxidant activity, and did not exhibit growth retardation due to enhanced asexual development caused by higher levels of linoleic acid. Therefore, we suggested that a light-enriched environment with SDAY media was more optimal than dark condition for cultivation of C. pruinosa mycelia as biopharmaceutical or nutraceutical resources.

    A cross sectional descriptive study, which involved government hospitals and health clinics from Peninsular Malaysia sought to identify the continuing professional education (CPE) needs and their readiness for E-learning. This paper focuses on the first phase of that study that aimed to determine the factors that influence nurses' participation in CPE. Multistage cluster sampling was used to recruit 1,000 nurses randomly from 12 hospitals and 24 health clinics from four states in Peninsular Malaysia who agreed to be involved. The respondent rate was 792 (79.2%), of which 562 (80%) had participated in CPE in the last 12 months. Findings suggested that updating knowledge and providing quality care are the most important factors that motivate participation in CPE, with respective means of 4.34 and 4.39. All the mean scores for educational opportunity were less than 3.0. Chi-square tests were used to test the association of demographic data and CPE participation. All demographical data were significantly associated with CPE participation, except marital status. Implementation of mandatory CPE is considered an important measure to increase nurse's participation in CPE. However, effective planning that takes into consideration the learning needs of nurses is recommended. Copyright © 2011 Korean Society of Nursing Science. Published by Elsevier B.V.

    The goal of this work was to analyse the profile of microbial volatile organic compounds (MVOCs) emitted by moulds growing on parchment samples, in search of particular volatiles mentioned in the literature as indicators of active mould growth. First, the growth of various moulds on samples of parchment was assessed. Those species that showed collagenolytic activity were then inoculated on two types of media: samples of parchment placed on media and on media containing amino acids that are elements of the structure of collagen. All samples were prepared inside 20-ml vials (closed system). In the first case, the media did not contain any sources of organic carbon, nitrogen, or sulphur, i.e. parchment was the only nutrient for the moulds. A third type of sample was historical parchment prepared in a Petri dish without a medium and inoculated with a collagenolytically active mould (open system). The MVOCs emitted by moulds were sampled with the headspace-SPME method. Volatiles extracted on DVB/CAR/PDMS fibres were analysed in a gas chromatography-mass spectrometry system. Qualitative and quantitative analyses of chromatograms were carried out in search of indicators of metabolic activity. The results showed that there are three groups of volatiles that can be used for the detection of active forms of moulds on parchment objects. To the best of our knowledge, this is the first work to measure MVOCs emitted by moulds growing on parchment.

    To explore if active learning principles be applied to nursing bioscience assessments and will this influence student perception of confidence in applying theory to practice? A review of the literature utilising searches of various databases including CINAHL, PUBMED, Google Scholar and Mosby's Journal Index. The literature search identified research from twenty-six original articles, two electronic books, one published book and one conference proceedings paper. Bioscience has been identified as an area that nurses struggle to learn in tertiary institutions and then apply to clinical practice. A number of problems have been identified and explored that may contribute to this poor understanding and retention. University academics need to be knowledgeable of innovative teaching and assessing modalities that focus on enhancing student learning and address the integration issues associated with the theory practice gap. Increased bioscience education is associated with improved patient outcomes therefore by addressing this "bioscience problem" and improving the integration of bioscience in clinical practice there will subsequently be an improvement in health care outcomes. From the literature several themes were identified. First there are many problems with teaching nursing students bioscience education. These include class sizes, motivation, concentration, delivery mode, lecturer perspectives, student's previous knowledge, anxiety, and a lack of confidence. Among these influences the type of assessment employed by the educator has not been explored or identified as a contributor to student learning specifically in nursing bioscience instruction. Second that educating could be achieved more effectively if active learning principles were applied and the needs and expectations of the student were met. Lastly, assessment influences student retention and the student experience and as such assessment should be congruent with the subject content, align with the learning

    In the present study, a simple, sensitive, specific and rapid liquid chromatography (LC) tandem mass spectrometry (MS/MS) method was developed and validated according to the Food and Drug Administration (FDA) guidelines for estimation of IIIM-MCD-211 (a potent oral candidate with promising action against tuberculosis) in mice plasma using carbamazepine as internal standard (IS). Bioanalytical method consisted of one step protein precipitation for sample preparation followed by quantitation in LC-MS/MS using positive electrospray ionization technique (ESI) operating in multiple reaction monitoring (MRM) mode. Elution was achieved in gradient mode on High Resolution Chromolith RP-18e column with mobile phase comprised of acetonitrile and 0.1% (v/v) formic acid in water at the flow rate of 0.4mL/min. Precursor to product ion transitions (m/z 344.5/218.4 and m/z 237.3/194.2) were used to measure analyte and IS, respectively. All validation parameters were well within the limit of acceptance criteria. The method was successfully applied to assess the pharmacokinetics of the candidate in mice following oral (10mg/kg) and intravenous (IV; 2.5mg/kg) administration. It was also effectively used to quantitate metabolic stability of the compound in mouse liver microsomes (MLM) and human liver microsomes (HLM) followed by its in-vitro-in-vivo extrapolation.

    Elderly people perceive their own ageing in very different ways and the aim of the present study was to explore age identity, the perception of "old age", the role of physical activity in the socialization of elderly people and social influences on physical activity in elderly people living in a nursing home. Questionnaires were answered by 75 nursing home residents (79 +/- 8 years old; 19 males, 56 females), coming from two different Slovenian regions. Subjective age ("felt age") was on average 5.5 years less than chronological age. Neither increasing chronological age nor subjective age was significantly correlated with a negative perception of health. Subjective age was neither correlated with any of the statements related to well-being and satisfaction with life. The importance of health in old age was confirmed by significant correlation of health status with perception of one's well-being and satisfaction with life. Interestingly, the age at which one perceives a person as having become old was not significantly related to one's own age. Nursing home residents in general associate old age with physical impairment and poor health. Slight differences between genders were noted; men grade retirement and communication difficulties with younger people as more prominent in old age. Interaction with other residents seems to be an important component of physical activity, as participants grade the importance of socializing during exercise quite highly; no significant differences between regions nor between men and women were noted. The social influence on physical activity did not differ significantly between genders and observed regions; the presence of negative social influence was relatively low. Furthermore, in the third period of life, physical activity plays an important socialization role and is, at the same time, influenced by the beliefs and ideas of the environment.

    To provide evidence on the effectiveness of simulation activities on the clinical decision-making abilities of undergraduate nursing students. Based on previous research, it was hypothesised that the higher the cognitive score, the greater the ability a nursing student would have to make informed valid decisions in their clinical practice. Globally, simulation is being espoused as an education method that increases the competence of health professionals. At present, there is very little evidence to support current investment in time and resources. Following ethical approval, fifty-eight third-year undergraduate nursing students were randomised in a pretest-post-test group-parallel controlled trial. The learning environment preferences (LEP) inventory was used to test cognitive abilities in order to refute the null hypothesis that activities in computer-based simulated learning environments have a negative effect on cognitive abilities when compared with activities in skills laboratory simulated learning environments. There was no significant difference in cognitive development following two cycles of simulation activities. Therefore, it is reasonable to assume that two simulation tasks, either computer-based or laboratory-based, have no effect on an undergraduate student's ability to make clinical decisions in practice. However, there was a significant finding for non-English first-language students, which requires further investigation. More longitudinal studies that quantify the education effects of simulation on the cognitive, affective and psychomotor attributes of health science students and professionals from both English-speaking and non-English-speaking backgrounds are urgently required. It is also recommended that to achieve increased participant numbers and prevent non-participation owing to absenteeism, further studies need to be imbedded directly into curricula. This investigation confirms the effect of simulation activities on real-life clinical

    Full Text Available Convolvulus austroaegyptiacus Abdallah & Sa’ad (CA and Convolvulus pilosellifolius Desr. (CP are commonly used in the Saudi Arabia folk medicine. They are potent in treating the ulcers and skin diseases. The lack of information about their biological activities led us to investigate the possible biological activities by determination of antibacterial and antioxidant activities of total ethanolic extracts and various fractions. Total flavonoid contents of the plants were determined by colorimetric method while total phenols were determined by using Folin-Ciocalteu method. In vitro antibacterial activity was studied against E. coli, P. aeruginosa, and B. subtilis, and the total antioxidant capacity was evaluated by radical scavenging method. IC50 were found to be 21.81, 17.62, and 3.31 μg/mL for CA, CP, and vitamin C, respectively, while the lowest MIC value of 0.25 mg/mL was recorded with CP extract against B. subtilis. Around 21 compounds are tentatively elucidated from both plants using rapid, simple, and high-resolution analytical technique for chemical profiling of natural compounds by direct analysis in real-time of flight-mass spectrometry, of which 17 were not isolated or reported previously.

    To describe how registered nurses having undergone a web-based learning activity perceive their self-efficacy and competence to support patients with smoking cessation in connection with surgery. Smoking cessation in connection with surgery reduces postoperative complications, and the support patients get from registered nurses may be important in helping them become smoke-free in connection with their surgery. Therefore, registered nurses are in need of enhanced understanding about which kind of counselling is the most effective for smoking cessation. Educating large groups of registered nurses in a digital environment appears to be a flexible and cost-effective way. A convergent mixed-method design with data collection was done using questionnaires (n = 47) and semistructured interviews (n = 11). Inclusion criteria were registered nurses in surgical wards. The samples were nonprobability and modified nested. Descriptive statistics and content analysis were used for data analysis. After completing the web-based learning activity, the registered nurses perception was that of good self-efficacy and increased competence in supporting patients with smoking cessation in connection with surgery. They improved their understanding of how to talk about smoking cessation with patients in dialogue using open-ended questions. Nevertheless, the registered nurses requested opportunities for dialogue and interaction with colleagues or topic experts. The results indicate that registered nurses can enhance their competence in supporting patients to embrace smoking cessation by learning in a digital environment. Self-efficacy and understanding of the topic seems to motivate registered nurses to counsel patients about smoking cessation. Findings from this study will be of particular interest to educators in healthcare settings who can devise further development of web-based learning activities. © 2017 John Wiley & Sons Ltd.

    The goal of the study has been to learn about physicians' and nurses' awareness of the professional activities that are being performed by their colleague in the physician-nurse team. Postal questionnaires were sent out to occupational physicians and nurses in Poland. The analysis includes responses from 232 pairs of physician-nurse teams. The knowledge among occupational professionals about tasks performed by their colleagues in the physician-nurse team seems to be poor. Respondents were asked about who performs tasks from each of 21 groups mentioned in the Occupational Medicine Service Act. In the case of only 3 out of 21 groups of tasks, the rate of non-consistence in answers was lower than 30%. A specified number of professionals performed their tasks on the individual basis. Although in many cases their team colleagues knew about those activities, there was a major proportion of those who had no awareness of such actions. Polish occupational physicians and nurses perform a variety of tasks. Occupational nurses, besides medical role, also play important organizational roles in their units. The cooperation between the two professional groups is, however, slightly disturbed by the deficits in communication. This issue needs to be improved for the betterment of operations within the whole system. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

    Curcuminoids possess powerful antioxidant activity as demonstrated in many chemical in vitro tests and in several in vivo trials. Nevertheless, the mechanism of this activity is not completely elucidated and studies on the in vivo antioxidant effects are still needed. Metabolomics may be used as an attractive approach for such studies and in this paper, we describe the effects of oral administration of a Curcuma longa L. extract (150 mg/kg of total curcuminoids) to 12 healthy rats with particular attention to urinary markers of oxidative stress. The experiment was carried out over 33 days and changes in the 24-h urine samples metabolome were evaluated by (1)H NMR and HPLC-MS. Both techniques produced similar representations for the collected samples confirming our previous study. Modifications of the urinary metabolome lead to the observation of different variables proving the complementarity of (1)H NMR and HPLC-MS for metabolomic purposes. The urinary levels of allantoin, m-tyrosine, 8-hydroxy-2'-deoxyguanosine, and nitrotyrosine were decreased in the treated group thus supporting an in vivo antioxidant effect of the oral administration of Curcuma extract to healthy rats. On the other hand, urinary TMAO levels were higher in the treated compared to the control group suggesting a role of curcumin supplementation on microbiota or on TMAO urinary excretion. Furthermore, the urinary levels of the sulphur containing compounds taurine and cystine were also changed suggesting a role for such constituents in the biochemical pathways involved in Curcuma extract bioactivity and indicating the need for further investigation on the complex role of antioxidant curcumin effects.

    Sida tuberculata is found in a region of South America and has traditionally been consumed as an infusion or tea. The chemical composition and antifungal activity of aqueous infusions from leaves and roots were investigated. LC-ESI-MS mass spectra were successfully obtained and used to identify four ecdysteroids: 20-hydroxyecdysone-3-O-β-D-glycopyranoside, 20-hydroxyecdysone, 20-hydroxyecdysone-3-O-β-D-xylose and a hydroxyecdysterone derivative. The in vitro antifungal activity was studied, and the minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) were established against Candida krusei isolates. The antibiofilm activity was evaluated by the determination of the biofilm removal efficiency in contaminated central venous catheter (CVC) coupons. The preparations exhibited antifungal activity against the species tested, with MICs ranging from 3.90 to 62.50 μg/ml. The infusion removed the C. krusei biofilm after 90 min of exposure. The observed bioactivity and composition of ecdysteroids will contribute to the future development of antifungal substances for clinical use or as food additives. Copyright © 2015 Elsevier Ltd.

    to assess the effects of a workplace physical activity (WPA) program on levels of anxiety, depression, burnout, occupational stress and self-perception of health and work-related quality of life of a nursing team in a palliative care unit. the WPA was conducted five days per week, lasting ten minutes, during three consecutive months. Twenty-one nursing professionals were evaluated before and after the intervention, with the Hospital Anxiety and Depression Scale, the Maslch Burnout Inventory, and the Job Stress Scale. The changes in self-perceived health and work-related quality of life were measured using a semi-structured questionnaire. the WPA did not yield significant results on the levels of anxiety, depression, burnout or occupational stress. However, after the intervention, participants reported improved perceptions of bodily pain and feeling of fatigue at work. the WPA did not lead to beneficial effects on occupational stress and psychological variables, but it was well accepted by the nursing professionals, who reported improvement in perceptions of health and work-related quality of life.

    To characterize rehabilitation services in two types of postacute facilities in patients who underwent hip replacement following a hip fracture. Multisite prospective observational cohort from 6 freestanding skilled nursing facilities and 11 inpatient rehabilitation facilities. Patients (n = 218) with hip fracture who had either hemiarthroplasty or total hip arthroplasty followed by rehabilitation at skilled nursing facilities or inpatient rehabilitation facilities were enrolled. Using a point-of-care methodology, we recorded data from actual physical therapy and occupational therapy sessions completed including functional outcomes during the postacute admission. Onset time from surgical repair to rehabilitation admission was not significantly different between sites. Average skilled nursing facilities length of stay was 24.7 +/- 13.6 days, whereas inpatient rehabilitation facilities was 13.0 +/- 5.7 days (P inpatient rehabilitation facilities. For weekdays only, these data changed to 1.6 in skilled nursing facilities and 2.6 hrs per patient in inpatient rehabilitation facilities (P inpatient rehabilitation facilities accrued more time for gait training and exercise in physical therapy, which was found to be 48% and 40% greater, respectively, through day 8. In occupational therapy, patients of inpatient rehabilitation facilities had more time allocated to lower body dressing and transfers. Significant differences in rehabilitation activities were observed, and intensity was notably different within the first 8 therapy days even though baseline demographics and medical complexity were comparable across facility types. Our data suggest that after more complex hip replacement surgery, hip fracture patients can tolerate more intensive therapy earlier within the rehabilitation program.

    This study examined the effects of a giant (4×3 m) exercising board game intervention on ambulatory physical activity (PA) and a broader array of physical and psychological outcomes among nursing home residents. A quasi-experimental longitudinal study was carried out in two comparable nursing homes. Ten participants (aged 82.5±6.3 and comprising 6 women) meeting the inclusion criteria took part in the 1-month intervention in one nursing home, whereas 11 participants (aged 89.9±3.1 with 8 women) were assigned to the control group in the other nursing home. The giant exercising board game required participants to per-form strength, flexibility, balance and endurance activities. The assistance provided by an exercising specialist decreased gradually during the intervention in an autonomy-oriented approach based on the self-determination theory. The following were assessed at baseline, after the intervention and after a follow-up period of 3 months: PA (steps/day and energy expenditure/day with ActiGraph), cognitive status (mini mental state examination), quality of life (EuroQol 5-dimensions), motivation for PA (Behavioral Regulation in Exercise Questionnaire-2), gait and balance (Tinetti and Short Physical Performance Battery), functional mobility (timed up and go), and the muscular isometric strength of the lower limb muscles. In the intervention group, PA increased from 2,921 steps/day at baseline to 3,358 steps/day after the intervention (+14.9%, P =0.04) and 4,083 steps/day (+39.8%, P =0.03) after 3 months. Energy expenditure/day also increased after the intervention (+110 kcal/day, +6.3%, P =0.01) and after 3 months (+219 kcal/day, +12.3%, P =0.02). Quality of life ( P <0.05), balance and gait ( P <0.05), and strength of the ankle ( P <0.05) were also improved after 3 months. Such improvements were not observed in the control group. The preliminary results are promising but further investigation is required to confirm and evaluate the long-term effectiveness

    To enumerate nurses' health-related behaviour by critically appraising studies on tobacco smoking, physical activity, alcohol consumption and dietary habits. Nurses represent the largest occupational group in healthcare systems internationally and have an established and expanding public health role. Nurses own health-related behaviour is known to impact nurses' ability and confidence to engage in health promotion, and how patients receive and respond to advice and guidance nurses' give. However, there has been no comprehensive and comparable assessment of evidence on nurses' health-related behaviours. Quantitative systematic review of prevalence of tobacco smoking, physical activity, alcohol consumption and dietary habits. Systematic searches for literature published between January 2000 and February 2015 and indexed in Medical Literature Analysis and Retrieval System, Cumulative Index to Nursing and Allied Health Literature and Psychological Information. Eligibility criteria will be applied to titles and abstracts by two reviewers independently. Full text will be reviewed and the same criteria and process applied. Two reviewers will independently assess study quality guided by the Joanna Briggs Institute handbook for the systematic review of prevalence and incidence data. Discrepancies in eligibility or quality assessment will be resolved through discussion and, where required, a third reviewer. Data synthesis will be conducted and findings reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Enumerating prevalence of nurses' health-related behaviours is crucial to direct future research, inform public health policy, particularly around health promotion and to better support the nursing workforce through the development of behaviour change interventions.

    Five fruits species commonly cultivated and consumed in Madeira Island (Portugal) were investigated for their phenolic profile by means of reversed phase high-performance liquid chromatography coupled to diode array detection and electrospray ionisation mass spectrometry (HPLC-DAD-ESI/MS(n)) and antioxidant potential. A large number of compounds were characterised, flavonoids and phenolic acids being the major components found in target samples, 39 compounds (flavonoids, phenolic acids, terpenoids, cyanogenic glycosides and organic acids) were identified in cherimoyas, lemons, papayas, passion-fruits and strawberries for the first time. Furthermore, all samples were systematically analysed for their total phenolic and flavonoid contents along with two radical scavenging methods (ABTS and ORAC) for antioxidant activity measurement. Target fruits presented high phenolic contents which is responsible for most of the antioxidant activity against radical reactive species (R(2)>0.80). Quantitative data showed that anthocyanins, in particular pelargonidin-3-O-hexoside (>300 mg/100 mL), present only in strawberries were the compounds in largest amounts but are the ones which contribute less to the antioxidant activity.

    The consumption of polyphenols has frequently been associated with low incidence of degenerative diseases. Most of these natural antioxidants come from fruits, vegetables, spices, grains and herbs. For this reason, there has been increasing interest in identifying plant extract compounds. Polymeric tannins and monomeric flavonoids, such as catechin and epicatechin, in pine bark and green tea extracts could be responsible for the higher antioxidant activities of these extracts. The aim of the present study was to characterize the phenolic compounds in pine bark and green tea concentrated extracts using high-performance liquid chromatography coupled to electrospray ionization mass spectrometry (HPLC–ESI-QTOF-MS). A total of 37 and 35 compounds from pine bark and green tea extracts, respectively, were identified as belonging to various structural classes, mainly flavan-3-ol and its derivatives (including procyanidins). The antioxidant capacity of both extracts was evaluated by three complementary antioxidant activity methods: Trolox equivalent antioxidant capacity (TEAC), ferric reducing antioxidant power (FRAP) and oxygen radical absorbance capacity (ORAC). Higher antioxidant activity values by each method were obtained. In addition, total polyphenol and flavan-3-ol contents, which were determined by Folin–Ciocalteu and vanillin assays, respectively, exhibited higher amounts of gallic acid and (+)-catechin equivalents.

    Full Text Available In this study the qualitative, quantitative and microbial determination of the aqueous extract of comfrey root was done. The qualitative and quantitative analyses were done by the UHPLC-DAD-HESI-MS method. As major bioactive compounds, allantoin, rosmarinic acid and ellagic acid were identified and their quantification was also done. The obtained results showed a high content of allantoin, ellagic acid and rosmarinic acid (8.91, 7.4 and 12.8%, respectively which indicated that the comfrey root can be used as a source for the isolation of these three compounds. The results obtained by the determination of the antimicrobial activity showed that Escherichia coli ATCC8739 and Salmonela typhimirium ATCC6538 were most sensitive to the aqueous extract of comfrey root. The results showed that allantoin did not express the antimicrobial activity on all the investigated bacteria species, and based on this it can be concluded that allantoin is not responsible for the antimicrobial activity of the aqueous extract of comfrey root.

Methods Longitudinal data were collected on nursing home residents with moderate (n = 7001 or severe (n = 4616 dementia in one US state from the US national Minimum Data Set (MDS. Severity of dementia was determined by the MDS Cognitive Performance Scale (CPS. Physical function was assessed by summing the seven items (bed mobility, transfer, locomotion, dressing, eating, toilet use, personal hygiene on the MDS activities of daily living (ADL Long Form scale. Mean change over time of MDS-ADL scores were estimated at three and six months for residents with moderate (CPS score of 3 and severe (CPS score of 4 or 5 dementia. Results Physical function in residents with moderate cognitive impairment deteriorated over six months by an average of 1.78 points on the MDS-ADL Long Form scale, while those with severe cognitive impairment declined by an average of 1.70 points. Approximately one quarter of residents in both groups showed some improvement in physical function over the six month period. Residents with moderate cognitive impairment experienced the greatest deterioration in early-loss and mid-loss ADL items (personal hygiene, dressing, toilet use and residents with severe cognitive impairment showed the greatest deterioration in activities related to eating, a late loss ADL. Conclusion The MDS-ADL Long Form scale detected clinically meaningful change in physical function in a large cohort of long-stay nursing home residents with moderate to severe dementia, supporting its use as a research tool in future studies.

    2016-01-01

    Full Text Available The 13 million nurses worldwide constitute most of the global healthcare workforce and are uniquely positioned to engage with others to address disparities in healthcare to achieve the goal of better health for all. A new vision for nurses involves active participation and collaboration with international colleagues across research practice and policy domains. Nursing can embrace new concepts and a new approach—“One World, One Health”—to animate nursing engagement in global health, as it is uniquely positioned to participate in novel ways to improve healthcare for the well-being of the global community. This opinion paper takes a historical and reflective approach to inform and inspire nurses to engage in global health practice, research, and policy to achieve the Sustainable Development Goals. It can be argued that a colonial perspective currently informs scholarship pertaining to nursing global health engagement. The notion of unidirectional relationships where those with resources support training of those less fortunate has dominated the framing of nursing involvement in low- and middle-income countries. This paper suggests moving beyond this conceptualization to a more collaborative and equitable approach that positions nurses as cocreators and brokers of knowledge. We propose two concepts, reverse innovation and two-way learning, to guide global partnerships where nurses are active participants.

    A hyperintense rim on susceptibility in chronic MS lesions is consistent with iron deposition, and the purpose of this study was to quantify iron-related myelin damage within these lesions as compared with those without rim. Forty-six patients had 2 longitudinal quantitative susceptibility mapping with automatic zero reference scans with a mean interval of 28.9 ± 11.4 months. Myelin water fraction mapping by using fast acquisition with spiral trajectory and T2 prep was obtained at the second time point to measure myelin damage. Mixed-effects models were used to assess lesion quantitative susceptibility mapping and myelin water fraction values. Quantitative susceptibility mapping scans were on average 6.8 parts per billion higher in 116 rim-positive lesions compared with 441 rim-negative lesions ( P quantitative susceptibility mapping values of both the rim and core regions ( P Quantitative susceptibility mapping scans and myelin water fraction in rim-positive lesions decreased from rim to core, which is consistent with rim iron deposition. Whole lesion myelin water fractions for rim-positive and rim-negative lesions were 0.055 ± 0.07 and 0.066 ± 0.04, respectively. In the mixed-effects model, rim-positive lesions had on average 0.01 lower myelin water fraction compared with rim-negative lesions ( P quantitative susceptibility mapping scan was negatively associated with follow-up myelin water fraction ( P Quantitative susceptibility mapping rim-positive lesions maintained a hyperintense rim, increased in susceptibility, and had more myelin damage compared with rim-negative lesions.

    Two Senecio plants, Senecio cannabifolius Less. and its variety S. cannabifolius Less. var. integrifolius (Kiodz.) Kidam., were both used as the raw material of Feining granule, a traditional Chinese medicine product for treating respiratory diseases. In this study, the chemical profiles of these two plants were investigated and compared by liquid chromatography-mass spectrometry (LC-MS) and nuclear magnetic resonance (NMR). A total number of 83 constituents, including 55 organic acids, 11 flavonoids, 4 alkaloids, 3 terpenes and 10 other types of compounds, were characterized. The results indicated that the levels of most flavonoids were higher in S. cannabifolius than in S. cannabifolius var. integrifolius, however, the levels of hepatotoxic pyrrolizidine alkaloids (PAs) were higher in S. cannabifolius var. integrifolius than in S. cannabifolius. Fifteen constituents were evaluated on lipopolysaccharides (LPS) induced RAW 264.7 cells, and eleven of them showed inhibition effect against nitric oxide (NO) production. Finally, the levels of ten major constituents (including seven anti-inflammatory active ones) and two PAs in Feining granule from two Senecio plants were determined and compared by the LC-UV and LC-MS methods, respectively. It was found that one organic acid (homogentisic acid) and two PAs (seneciphylline and senecionine) had higher contents in the preparation of S. cannabifolius var. integrifolius than in that of S. cannabifolius, however, the situations were inverse for the levels of four organic acids and flavonoids (chlorogenic acid, hyperoside, isoquercitrin, and isochlorogenic acid B). Based on the above results, S. cannabifolius might be a better raw material for Feining granule than S. cannabifolius var. integrifolius, because it contained more anti-inflammatory constituents and less hepatotoxic PAs than the latter. However, more pharmacological evaluations should be carried out to support the selection. The results in this study were helpful

    Multiple sclerosis (MS) is a disease of the central nervous system. The cause is unknown. There are about 80-160 people with MS per 100,000 population, with twice as many women affected as men. The management of individuals with MS includes treatment of acute relapses and chronic symptoms. The care of MS patients is provided by various healthcare professionals, such as general practitioners (GPs), neurologists, physiotherapists, occupational therapists and nurses. Some MS patients have access to an MS specialist nurse, although this provision varies geographically. The aim of this report is to assess the effectiveness and relative cost-effectiveness of MS specialist nurses in improving care and outcomes for patients with MS. A systematic review of the literature, involving a range of databases, was performed. Full details are described in the main report. Only one study was identified that tried to evaluate the benefit of MS specialist nurses. The study concluded that MS patients and their carers found the MS specialist nurse to be helpful, particularly in improving their knowledge of MS, ability to cope, mood and confidence about the future. GPs also reported finding the nurse to be helpful with their MS patients, and 40% of the GPs stated they would purchase the services of an MS specialist nurse if their practices became fundholding. However, there were considerable methodological weaknesses inherent in the study design, and it was unclear whether the results of the study could be extrapolated to other settings or to other MS patient groups. RESULTS - ONGOING RESEARCH: There are two ongoing research studies regarding MS specialist nurses. One of these studies involves the provision of MS nurses to several areas, but also has two control populations to allow evaluation of the health benefits of the nurses to MS patients and their carers. This study will help to fill the evidence gap. RESULTS - COSTS: The costs of providing MS specialist nurses consist of their

The test-retest method was used for the reliability of stability. all indicators of the SVAT have achieved a degree of consensus not less than 80% demonstrating its content validity. The face validity is demonstrated by an average score equal to or greater than 7 obtained by all indicators. The reliability of internal consistency of the SVAT was appraised by Cronbach's alpha that was 0.987 for the entire instrument. The reliability of the stability has been calculated through the correlation's coefficient expressed by Pearson's r that was 0.983 (p = 1.3E-198). in Italy there is no a "gold standard" tool to evaluate the clinical performance of nursing students during and at the end of their clinical training. The SVAT proves to be a valuable and reliable tool it furthermore could stimulate the discussion and the debate among educators and nurses, so that also in our country, it may be possible develop and refine tools that support the evaluation of clinical skills of nursing students.

    Background It is commonly assumed that oncology nurses experience high job-related burnout and high turnover because their work involves inherent stressors such as caring for patients with serious and often life-threatening illness. Objectives The objectives of this study were to examine the differences in outcomes such as job dissatisfaction and burnout between oncology nurses and medical-surgical nurses, and to identify factors that affect oncology nurse outcomes. Methods A secondary analysis of nurse survey data collected in 2006 including 4047 nurses from 282 hospitals in 3 states was performed; t test and χ2 test compared differences between oncology nurses and medical-surgical nurses in nurse outcomes and their assessments of nurse practice environment, as measured by the Practice Environment Scale of the Nursing Work Index. Logistic regression models estimated the effect of nurse practice environment on 4 nurse-reported outcomes: burnout, job dissatisfaction, intention to leave the current position, and perceived quality of care. Results Oncology nurses reported favorable practice environments and better outcomes than did medical-surgical nurses. All 4 subscales of the Practice Environment Scale of the Nursing Work Index studied were significantly associated with outcomes. Specifically, nurses who reported favorable nursing foundations for quality of care (eg, active in-service or preceptorship programs) were less likely to report burnout and leave their current position. Conclusions Better practice environments, including nurse foundations for quality care, can help to achieve optimal nurse outcomes. Implications for Practice Improving hospital practice environments holds significant potential to improve nurse well-being, retention, and quality of care. Specifically, hospitals should consider preceptor programs and continuing education and increase nurses’ participation in hospital decision making. PMID:22751101

    Triacylglycerol (TAG) lipases hydrolyze ester bonds in TAG and release diacylglycerol (DAG), monoacylglycerol (MAG), and FA. We present a one-step chemical derivatization method for label-free quantification of a mixture of TAG, DAG, and MAG following lipase assay by ESI-MS. Because the ionization efficiencies of TAG, DAG, and MAG are not identical, lipase reaction products, DAG and MAG, are derivatized to TAG species by esterifying their hydroxyl groups using acyl chloride, whose acyl chain contains one less (or one more) -CH 2 group than that of substrate TAG. This resulted in three TAG species that were separated by 14 Da from one another and exhibited similar ion responses representing their molar amounts in the mass spectra. A good linear correlation was observed between peak intensity ratios and molar ratios in calibration curve. This method enables simultaneous quantification of TAG, DAG, and MAG in lipase assay and, in turn, allows stoichiometric determination of the concentrations of FAs released from TAG and DAG separately. By applying this strategy to measure both TAG and DAG lipolytic activities of the yeast Tgl2 lipase, we demonstrated its usefulness in studying enzymatic catalysis, as lipase enzymes often show dissimilar activities toward these lipids.

    Neglected diseases are those that are prevalent in developing countries, even with a rich biodiversity. These diseases still persist because of the lack of scientific studies, government negligence or failures of the public health system. This study aims to identify the composition of extracts and fractions from Psidium brownianum and Psidium guajava through LC-MS, to evaluate its in vitro anti-parasitic and cytotoxic activity against Trypanosoma cruzi, Leishmania brasiliensis and L. infantum epismastigote and promastigote forms, as well as mammalian cells. The results showed the presence of chemical constituents in the two Psidium species as quercetin, myricetin and gallic acid derivatives. The P. brownianum extract and fractions showed low toxicity at all tested concentrations and all samples were effective at the concentration of 1000μg/mL against the parasites, with the extract being the most efficient against the L. infantum promastigote form. The ethanolic extract, and the flavonoid and tannic fractions, from P. guajava showed low toxicity for the fibroblasts. All samples showed effectiveness at the highest concentration tested and the extract was more effective against the promastigote forms tested. The results showed that the species Psidium brownianum and Psidium guajava demonstrated an anti-parasitic activity against the T. cruzi, L. brasiliensis and L. infantum parasite cell lines indicating these species as an alternative therapy given their efficacy in the in vitro assays performed, opening the possibility for new biological studies to further this knowledge through in vivo assays.

    A 60% azadirachtin-A concentrate has been obtained through repeated precipitation with hexane from a methanolic solution of a 20% concentrate. Azadirachtin-A (90%) has been obtained by medium-pressure liquid chromatography of the 60% concentrate with an RP-18 column and a methanol + water (1 + 1 by volume) solvent system. Catalytic hydrogenation of the 60 and 90% azadirachtin concentrates yielded the corresponding tetrahydroazadirachtin concentrates. Dihydroazadirachtin and tetrahydroazadirachtin formed during the first 5 h of hydrogenation were identified by LC-ESI-MS on the basis of their unique mass fragmentation pattern. The efficacy of tetrahydroazadirachtin concentrates in inhibiting the feeding and growth of Helicoverpa armigera (Hübner) larvae has been compared with that of azadirachtin concentrates. They were in general more active and deterred larvae from feeding at all concentrations. Tetrahydroazadirachtin-A (90%) and azadirachtin-A (90%) with respective IC(50) values of 280 and 390 mg L(-1) were effective as insect growth regulators, while tetrahydroazadirachtin-A (90%) displayed higher antifeedant activity (AI(50) 14 mg L(-1)) against the test insect.

    Thirteen trace elements and active constituents of 40 batches of Lonicera japonica flos and Lonicera flos were comparatively studied using inductively coupled plasma mass-spectrometry (ICP-MS) and high-performance liquid chromatography-photodiode array (HPLC-PDA). The trace elements were 24 Mg, 52 Cr, 55 Mn, 57 Fe, 60 Ni, 63 Cu, 66 Zn, 75 As, 82 Se, 98 Mo, 114 Cd, 202 Hg, and 208 Pb, and the active compounds were chlorogenic acid, 3,5-O-dicaffeoylquinc acid, 4,5-O-dicaffeoylquinc acid, luteolin-7-O-glucoside, and 4-O-caffeoylquinic acid. The data of 18 variables were statistically processed using principal component analysis (PCA) and discriminate analysis (DA) to classify L. japonica flos and L. flos. The validated method was developed to divide the 40 samples into two groups based on the PCA in terms of 18 variables. Furthermore, the species of Lonicera was better discriminated by using DA with 12 variables. These results suggest that the method and statistical analysis of the contents of trace elements and chemical components can classify the L. japonica flos and L. flos using 12 variables, such as 3,5-O-dicaffeoylquincacid, luteolin-7-O-glucoside, Cd, Mn, Hg, Pb, Ni, 4-O-caffeoyl-quinic acid, 4,5-O-dicaffeoylquinc acid, Fe, Mg, and Cr.

    The chemical composition of the essential oil obtained by steam distillation of the floral calyces of Ocotea bofo Kunth (Lauraceae) was studied by means of GC, GC-MS, and 1H, 13C, and bidimensional NMR (COSY, HSQC, HMBC). Twenty-five constituents were identified, and estragole (48.7%), alpha-phellandrene (19.6%) and sabinene (10.4%) were found to be the major components. Antimicrobial activity against six aerobic bacteria and five yeasts and antioxidant activity performed by photochemiluminescence (PCL), 1,1-diphenyl-2-picrylhydrazyl (DPPH), and beta-carotene bleaching assays are reported. The oil showed fair inhibiting properties against bacteria and a good inhibition against most yeasts. Its radical scavenging and chain-breaking antioxidant properties were comparable to or better than those provided by synthetic controls. Particular emphasis has been given to the use of NMR as a fast and reliable tool to discriminate O. bofo essential oil from other commercial anethole- and estragole-rich oils, namely, Illicium verum, Foeniculum vulgare, and Artemisia dracunculus.

    Nurses are the largest professional group within the health care workforce, and their work is perceived as being physically demanding. Regular physical activity helps to prevent or ameliorate cardiometabolic conditions (e.g. cardiovascular disease, diabetes). It is not known whether Canadian nurses are meeting current physical activity guidelines. To assess the influence of the workplace on the physical activity and cardiometabolic health of nurses from hospitals in the Champlain region of Ontario, Canada. A multi-centre, cross-sectional study. Hospitals in the Champlain Local Health Integration Network of Ontario. Nurses wore an ActiGraph accelerometer to objectively assess levels of moderate-to-vigorous intensity physical activity measured in minutes/day in bouts ≥10 min. All completed the Perceived Workplace Environment (PWE) scale and International Physical Activity Questionnaire (IPAQ). Height, body mass, waist circumference, blood pressure and heart rate were measured, and body mass index (BMI) was determined. Each nurse's 5-year cardiovascular risk was calculated using the Harvard Score. A total of 410 nurses (94% female; mean ± SD: age = 43 ± 12 years) from 14 hospitals participated. Nurses spent an average of 96 ± 100 min/week in bouts ≥10 min of moderate-to-vigorous intensity physical activity; 23% of nurses met recommended physical activity guidelines. Nurses working 8- vs. 12-h shifts (16 ± 16 vs. 10 ± 11 min/day, p = 0.026), fixed vs. rotating shifts (15 ± 15 vs. 12 ± 13 min/day, p = 0.012) and casual vs. full-time (29 ± 17 vs. 13 ± 15 min/day, p physical activity in bouts ≥10 min. The average PWE score was 2.4 ± 0.9, with no association between PWE scores and moderate-to-vigorous intensity physical activity in bouts ≥10 min (p > 0.05). Nurses working 8-h shifts, fixed shifts and in urban hospitals reported better PWE scores (p physical activity guidelines

    Understanding the reproductive biology of endangered mountain gorillas (Gorilla beringei beringei) is essential for optimizing conservation strategies, determining any demographic impact of socioecological changes, and providing information for comparative studies of primates. Non-invasive techniques have been used to assess the reproductive function of many primates and the importance of validating the measurements of hormones metabolites is widely recognized because they may vary even within closely related species. To determine if it is possible to non-invasively monitor ovarian activity in wild mountain gorillas, we used enzyme immunoassays (EIA) to quantify both urinary and fecal excretion of immunoreactive pregnanediol-3-glucuronide (iPdG), defined as all metabolites detected by a pregnanediol-3-glucuronide immunoassay (PdG EIA). Simultaneously, we performed the liquid chromatography mass spectrometry (LC-MS) to quantify the excretion of pregnanediol in urine and feces. Samples were analyzed over nine cycles of five females from the habituated gorillas monitored by Karisoke Research Center, Rwanda. As an additional indicator for ovulation timing, estrone conjugates (E1C) were measured in a subset of urine samples. The concentrations of iPdG and pregnanediol measured in the same samples were significantly correlated. Urinary concentrations of iPdG and pregnanediol fluctuated over the menstrual cycle but did not reveal any cyclic pattern, whereas a typical preovulatory urinary E1C surge and postovulatory increases of fecal iPdG and pregnanediol were detected. The luteal peaks of iPdG and pregnanediol levels in feces were on average 2.8 and 7.6 times higher, respectively, than averaged levels in the corresponding follicular phase. The relative number of days with observed matings was higher within the presumed fertile window than in the preceding period. Overall, the results indicate that fecal analysis of iPdG and pregnanediol is suitable for detecting

    Increasing number of older adults lives in their own homes, but needs help in many daily routines. Domiciliary care nursing staff (DCNS) is often needed to support oral home care. However, information of nursing staff's knowledge, skills and activity in this task is sparse. The study aimed to assess DCNS knowledge, perceived skills and activities to support oral home care of older domiciliary care clients. The study was conducted among DCNS in one of the largest cities in Finland. All DCNS members (n = 465) received a questionnaire with 14 multiple choice and open questions regarding the perceived skills, knowledge and activities of oral health guidance of older domiciliary care clients. In total, 115 (25%) DCNS members returned the questionnaires. Frequencies, percentages, means and standard deviations were used to describe the samples and study variables. DCNS was categorised according to age and working years for group comparisons, which were assessed with chi-squared test. Knowledge concerning oral health was mostly on a high level. Around 50% of DCNS considered their knowledge regarding dental prosthesis hygiene as sufficient. Of the DCNS, 67% informed that they had received education on oral health care. However, over 50% of the DCNS had a need for further education in issues related to oral home care. DCNS were active in supporting most oral and prosthesis hygiene means, yet less in guidance concerning toothbrushing. Activity to support cleaning the interdental spaces was the weakest, in which only 12% of the respondents considered having average or excellent skills. Younger DCNS had better knowledge on oral home care due to recent education, but older staff members were more skilful in performing oral hygiene measures. There is a need for structured instructions and training on oral home care for DCNS. Oral home care should be taken into account more often and regularly. © 2018 Nordic College of Caring Science.

  14. The role of EBV in MS pathogenesis

    2006-01-01

    Environmental factors operate on a background of genetic susceptibility in the pathogenesis of MS. Human herpesviruses, notably Epstein-Barr virus (EBV), and human endogenous retroviruses are factors associated with MS. EBV association is found in epidemiological surveys where late EBV infection...... confers a higher risk of MS, and EBV reactivation also appears to be linked to disease activity in early MS. MS patients have elevated anti-EBV antibody responses, both in serum and cerebrospinal fluid. Molecular mimicry is found between certain EBV and myelin epitopes in the cell-mediated immune response....... EBV cannot stand alone as a causal factor of MS, but is likely to play an indirect role as an activator of the underlying disease process....

    Although feminism has been actively discussed and applied to nursing in Western societies since the 1980s, it is little known among Korean scholars as well as Korean nurses. This article explores the use of feminist perspectives in nursing science in other developed countries and suggests how feminism could be applied to nursing science in Korea. The literature related to nursing and feminism were reviewed in terms of nursing practice, education, and research. This article describes what feminism is and how feminism and nursing have evolved historically over time in other countries, especially in Western societies. In addition, it discusses how it can be applied to nursing practice, education, and research in Korea. Accepting feminist perspective in Korean nursing could benefit in empowering nurses by valuing nursing, by raising self-esteem of nurses, and by raising the consciousness of socio-political realities. Eventually it could benefit in changing and developing nursing science in Korea.

    Full Text Available Chemical constituents of liverwort (Porella cordaeana extracts have been identified using solid-phase microextraction-gas chromatography mass spectrometry (SPME-GC/MS. The methanol, ethanol and ethyl acetate extracts were rich in terpenoids such as sesquiterpene hydrocarbons (53.12%, 51.68%, 23.16%, and monoterpene hydrocarbons (22.83%, 18.90%, 23.36%, respectively. The dominant compounds in the extracts were β-phellandrene (15.54%, 13.66%, 12.10% and β-caryophyllene (10.72%, 8.29%, 7.79%, respectively. The antimicrobial activity of the extracts was evaluated against eleven food microorganisms using the microdilution and disc diffusion methods. The minimum inhibitory concentration (MIC varied from 0.50 to 2.00 mg/mL for yeast strains (Saccharomyces cerevisiae 635, Zygosacharomyces bailii 45, Aerobasidium pullulans L6F, Pichia membranaefaciens OC 71, Pichia membranaefaciens OC 70, Pichia anomala CBS 5759, Pichia anomala DBVPG 3003 and Yarrowia lipolytica RO13, and from 1.00 to 3.00 mg/mL for bacterial strains (Salmonella enteritidis 155, Escherichia coli 555 and Listeria monocytogenes 56Ly. Methanol extract showed better activity in comparison with ethanol and ethyl acetate extracts. High percentages of monoterpene and sesquiterpene hydrocarbons could be responsible for the better antimicrobial activity.

    Chemotherapy induced neuropathy causes excruciating pain to cancer patients. Wen-Luo-Tong (WLT), a traditional Chinese medicinal compound, has been used to alleviate anti-cancer drug such as oxaliplatin-induced neuropathic pain for many years. However, the current route of administration of WLT is inconvenient and the active ingredients and mechanism of action of WLT are still unclear. To address these issues, we developed a novel formulation of WLT (W/O microemulsion) for the ease of application. New ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) methods were employed for analysis of the ingredients. We identified seven ingredients that penetrated through the skin into the Franz cell receptor solution and four of those ingredients were retained in skin tissue when WLT microemulsion was applied. We tested the microemulsion formulation on an oxaliplatin-induced neuropathy rat model and showed that this formulation significantly decreased oxaliplatin-induced mechanical hyperalgesia responses. Schwann cells (SCs) viability experiment in vitro was studied to test the protective effect of the identified seven ingredients. The result showed that Hydroxysafflor Yellow A, icariin, epimedin B and 4-dihydroxybenzoic acid significantly increased the viability of SCs after injured by Oxaliplatin. Our report presents the first novel formulation of WLT with neuroprotective effect and ease of use, which has potential for clinical applications.

    Essential oils obtained from flowers, leaves and stems of Origanum vulgare L. ssp. viride (Boiss.) Hayek., growing wild in Ardabil Province (north-west Iran), were analyzed by GC and GC/MS. beta-Caryophyllene was the major constituent in all three oils (48.1%, 50.1% and 60.2%, respectively). Of the 19 components detected in the flower oil, comprising 96.3% of the total, the major components were 1,8-cineole (11.6%), alpha-pinene (6.9%), and gamma-cadinene (4.8%). 1-Octen-3-ol (23.8%), and 1,8-cineole (8.5%) predominated in the leafoil. In the stem oil, other main constituents were bicyclogermacrene (9.8%), 1,8-cineole (6.4%), borneol (5.1%), and pinocarvone (4.4%). The essential oils were evaluated for their antibacterial activity against 10 selected microorganisms. The data obtained contribute to the future use of certain essential oils as natural preservatives for food products, due to their safety and positive effect on shelf life.

    A highly sensitive, specific and rapid LC-ESI-MS/MS method has been developed and validated for the simultaneous quantification of bendamustine (BM) and γ-hydroxybendamustine (HBM) in small volume (20 µL) mice and dog plasma using phenacetin as an internal standard (IS) as per regulatory guidelines. Both the analytes and IS were extracted from mice and dog plasma using a liquid-liquid extraction method. Chromatography was achieved on Atlantis dC 18 column using an isocratic mobile phase (0.2% formic acid:acetonitrile, 25:75) at a flow rate of 0.40 mL/min. The total chromatographic run time was 3.0 min and the elution of BM, HBM and IS occurred at ~1.2, 1.2 and 2.0 min, respectively. A linear response function was established 0.11-518 ng/mL for both the analytes in mice and dog plasma. The intra- and inter-day accuracy and precisions were in the range of 3.46-12.9 and 3.63-8.23%; 1.15-9.00 and 7.86-9.49% for BM and HBM, respectively in mice plasma and 2.15-6.49 and 1.73-13.1%; 4.35-13.9 and 4.33-10.5% for BM and HBM, respectively in dog plasma.

    Graphical abstract: Heat map of hierarchical clustering of the testicular tissue samples (A) and serum samples (B) at the 2nd week. Red blocks indicate increased intensities whereas blue indicates decreased intensities. The above two columns represent model group and normal group. - Abstract: Triptolide is the major active ingredient of Tripterygium Glycosides (TG), a traditional Chinese medicine with very potent anti-inflammatory effects and has been used in China for the treatment of rheumatoid arthritis and many other inflammatory diseases. However, clinical application of triptolide is restricted due to its multiple side effects, especially male infertility. The mechanism of triptolide on reproduction toxicity remains unclear. In the present study, a GC–MS based metabolomic approach was employed to evaluate the mechanism of triptolide-induced reproductive toxicity as well as identify potential novel biomarkers for the early detection of spermatogenesis dysfunction. In brief, male mice were divided into two groups with or without triptolide intraperitoneal injection at 60 μg/kg/day for 2 weeks and toxic effect of triptolide on testicular tissues were examined by biochemical indicator analysis, testis histopathologic analysis, and sperm quantity analysis. Metabolomics technology was then performed to evaluate systematically the endogenous metabolites profiling. Our results demonstrated that triptolide suppressed the marker-enzymes of spermatogenesis and testosterone levels, decreased sperm counts, reduced the gonad index and destroyed the microstructure of testis. Multivariate data analysis revealed that mice with triptolide induced testicular toxicity could be distinctively differentiated from normal animals and 35 and 39 small molecule metabolites were changed significantly in testis and serum, respectively (Fold-changes >1.5, P < 0.05), in triptolide-treated mice.

    An acceleration in the professionalization of Italian nurses has taken place in recent years. This pattern, together with the increasing prevalence of kidney diseases and the decreasing number of active nephrologists, makes a new collaborative structure between nurses and nephrologists both possible and welcome. This article describes the recent changes and future prospects of the Italian nursing profession. Observations about nephrology are based on interviews conducted with key opinion leaders of nursing in nephrology and dialysis. Italian nurses have recently acquired a status of professional autonomy. Nursing training is now fully integrated in the university system and nurses have obtained more responsibilities and a higher status within healthcare organizations. Future developments may be related to the internal articulation of the profession, supported by master courses and specialist training. Another possible evolution refers to the ongoing restructuring of the healthcare system with an emphasis on nursing activities and skills rather than medical specialties, which will lead to new and stronger managerial roles for nurses. The increase in the prevalence of kidney diseases and the declining number of nephrologists will result in a change in the distribution and utilization of nephrology services. The professionalization of nurses allows a new work division with a task shift from doctors to nurses. Italian nephrologists should seek a preferential relationship with the nursing profession, also considering the nursing shortage in several regions. Possible means to accomplish this preferential relationship could be, in addition to task shifting, nurses' involvement in research, and support for postgraduate training.

    Although many psychiatric hospital nurses in Bahrain attend at least one continuing nursing education (CNE) activity per year, many others do not. This study explored these nurses' perceptions of CNE and factors that promote or hinder participation in CNE activities. A descriptive design was used to gather data from a convenience sample of 200 nurses working at the psychiatric hospital in Bahrain. Nurses believed that CNE improved the quality of patient care and patient outcomes, increased nurses' knowledge and skills, and kept them current with advances in nursing. Participation in CNE was hindered by unavailability of CNE activities related to psychiatric nursing. The majority of nurses had positive perceptions of CNE. Their participation was hindered by unavailability of CNE activities related to psychiatric nursing. Those responsible for planning continuing education in Bahrain should consider these findings when planning future CNE activities. Copyright 2012, SLACK Incorporated.

    To explore nursing home nurses' experiences and views of work identity. Nursing home nurses are in a unique position as they work at the interface of health and social care. Little is known about nursing home nurses' perceptions and experiences of working within this context. Evidence suggests that using the concept of work identity can support understanding of how workers make sense of their work. Hermeneutic phenomenological study. The study was carried out in seven nursing homes in North East England. Findings are based upon literary analysis of multiple episodic interviews with 13 nursing home nurses. Participants' responses suggested that nursing "residents" is different to nursing "patients," and nursing home nurses are required to modify their care activities to account for these differences. Participants also proposed that they are isolated and excluded from the rest of the healthcare workforce group. These issues led participants to feel uncertain about work identity. Many participants attempted to strengthen their work identity by aligning their role with what they perceived the "nurse identity" to be. Nurses' work activities and professional group identity influence their work identity. When work activities and professional group identity do not align with role expectations, as can be the case for nursing home nurses, work identity may be compromised. These nurses may attempt to change work practices to strengthen their work identity. Health- and social care providers need to account for work identity factors in the organisation of care, and planning and implementation of integrated health- and social care initiatives. © 2017 John Wiley & Sons Ltd.

    This study compared the sensitivity of various separation and ionization methods, including gas chromatography with an electron ionization source (GC-EI), liquid chromatography with an electrospray ionization source (LC-ESI), and liquid chromatography with a silver ion coordination ion spray source (LC-Ag(+) CIS), coupled to a mass spectrometer (MS) for steroid analysis. Chromatographic conditions, mass spectrometric transitions, and ion source parameters were optimized. The majority of steroids in GC-EI/MS/MS and LC-Ag(+) CIS/MS/MS analysis showed higher sensitivities than those obtained with other analytical methods. The limits of detection (LODs) of 65 steroids by GC-EI/MS/MS, 68 steroids by LC-Ag(+) CIS/MS/MS, 56 steroids by GC-EI/MS, 54 steroids by LC-ESI/MS/MS, and 27 steroids by GC-ESI/MS/MS were below cut-off value of 2.0 ng/mL. LODs of steroids that formed protonated ions in LC-ESI/MS/MS analysis were all lower than the cut-off value. Several steroids such as unconjugated C3-hydroxyl with C17-hydroxyl structure showed higher sensitivities in GC-EI/MS/MS analysis relative to those obtained using the LC-based methods. The steroids containing 4, 9, 11-triene structures showed relatively poor sensitivities in GC-EI/MS and GC-ESI/MS/MS analysis. The results of this study provide information that may be useful for selecting suitable analytical methods for confirmatory analysis of steroids. Copyright © 2015 John Wiley & Sons, Ltd.

    A mobile nursing station is an innovative cart that integrates a wireless network, information technology devices, and online charts. In addition to improving clinical work and workflow efficiencies, data is integrated among different information systems and hardware devices to promote patient safety. This study investigated the effectiveness of mobile nursing cart use. We compared different distributions of nursing activity working samples to evaluate the nursing information systems in terms of interface usability and usage outcomes. There were two parts of this study. Part one used work sampling to collect nursing activity data necessary to compare a unit that used a mobile nursing cart (mobile group, n = 18) with another that did not (traditional group, n = 14). Part two applied a nursing information system interface usability questionnaire to survey the mobile unit with nurses who had used a mobile nursing station (including those who had worked in this unit as floating nurses) (n = 30) in order to explore interface usability and effectiveness. We found that using the mobile nursing station information system increased time spent on direct patient care and decreased time spent on indirect patient care and documentation. Results further indicated that participants rated interface usability as high and evaluated usage effectiveness positively. Comments made in the open-ended question section raised several points of concern, including problems / inadequacies related to hardware devices, Internet speed, and printing. This study indicates that using mobile nursing station can improve nursing activity distributions and that nurses hold generally positive attitudes toward mobile nursing station interface usability and usage effectiveness. The authors thus encourage the continued implementation of mobile nursing stations and related studies to further enhance clinical nursing care.

  13. HPTLC-profiling of eleutherosides, mechanism of antioxidative action of eleutheroside E1, the PAMPA test with LC/MS detection and the structure–activity relationship

    Full Text Available Human body is constantly generating free radicals, which causes oxidative stress. Despite naturally occurring antioxidant systems in human body, free radicals cause lipid, proteins and DNA oxidation. New antioxidants are still urgent as well as their mechanisms of action should be explained. In this study, we investigated the mechanism by which eleutherosides B, E and E1 may act as antioxidants, identified eleutherosides in Eleutherococcus lasiogyne and Eleutherococcus giraldii, and explained in vitro the absorption of eleutheroside E1 based on passive transport. The DPPH∗ and DB-HPTLC tests were used to assess the antioxidant activity. Of the three eleutherosides, only eleutheroside E1 exhibited a strong anti-DPPH∗ activity (EC50 37.03 μg/mL; 63 mMol compared to the raw extracts (EC50 170 and 180 μg/mL for E. lasiogyne and E. giraldii. This activity was also confirmed by the DB-HPTLC autography technique. According to Załuski’s hypothesis, the antioxidant mechanism of eleutheroside E1 is based on the complexation of DPPH∗ molecule with its aryl radical. During this reaction, the aryl radical of eleutheroside E1 (E1∗ and DPPHH are created. Next, the aryl radical (E1∗ is complexed with another DPPH∗ molecule. Additionally, the aryl radical can be stabilized by the presence of the methoxy groups in the aromatic ring, which increases its antioxidative action. The HPTLC-identification of extracts showed the presence of eleutherosides B, E and E1 in both species. The PAMPA test coupled with LC/MS detection showed a low permeability of eleutheroside E1 across artificial membrane. Because eleutherosides belong to the polyphenols, the TPC and TFC were quantified. The TPC and TFC varied from 51.4 to 49.3 mg/g dry extract for TPC, and from 5.73 to 4.91 mg/g dry extract for TFC, for E. giraldii and E. lasiogyne, respectively. In conclusion, eleutheroside E1 in its pure form could be a chemopreventive ingredient of new pharmacological

  14. Casemix and nursing.

    The American Nurses' Association did not embrace the introduction of diagnosis related groups, believing they would not recognise nursing activity nor acuity and would bring about the economic demise of nursing. Australian nurses, by contrast, recognised the window of opportunity that the work towards Australian national diagnosis related groups and funding mechanisms provided to move nursing resources into the political and policy mainstream. This paper reviews the American and Australian nursing experience with casemix, acuity and cost weighting. It uses examples from more recent work to argue for the use of casemix information in new ways, for 'process improvement' or 'evidence-based management'. The paper concludes that the next great leap forward in casemix may require attention to building the information and human infrastructures, so that the valuable clinical-financial information produced by casemix-based information systems can truly inform management and policy.

Stimulating movement is associated with improvements in ADL performance. Therefore, movement stimulating interventions, such as ADL training and exercise, focus on optimizing ADL performance to improve QoL. This study aimed to evaluate the effect of three movement stimulating interventions on QoL and ADL performance in NH residents with dementia. Methods: In this 6-month double parallel randomized controlled trial, the effects of ADL training, a multicomponent aerobic and strength exercise training, and a combined ADL and exercise training were analyzed in 87 NH residents with dementia. The Global Deterioration Scale was used to classify the severity of dementia. Participants were screened at baseline using the 6 minute walk test and Mini-Mental State Examination. The Qualidem, and the Care Dependency Scale and Erlangen ADL test were evaluated at baseline, and after 3 and 6 months to measure QoL and ADL, respectively. Multilevel analyses were adjusted for baseline performance, age, and gender. Results: A 6-month ADL training positively affected overall QoL (p = 0.004 and multiple aspects of QoL, including care relationship (p = 0.004, positive self-image (p = 0.002, and feeling at home (p = 0.001, compared to care-as-usual. No benefits were observed of exercise on QoL. No benefits were observed of a combined ADL and exercise intervention on QoL. No effects were found of the three movement interventions on ADL performance. Conclusion: The results indicate

    Full Text Available MS-275 (entinostat and SAHA (vorinostat, two histone deacetylase (HDAC inhibitors currently in oncological trials, have displayed potent anti-rheumatic activities in rodent models of rheumatoid arthritis (RA. To further elucidate their anti-inflammatory mechanisms, the impact of MS-275 and SAHA on the p38 mitogen-activated protein kinase (MAPK signaling pathway and chemotaxis was assessed in human rheumatoid arthritic synovial fibroblastic E11 cells. MS-275 and SAHA significantly suppressed the expression of p38α  MAPK, but induced the expression of MAPK phosphatase-1 (MKP-1, an endogenous suppressor of p38α  in E11 cells. At the same time, the association between p38α and MKP-1 was up-regulated and consequently, the activation (phosphorylation of p38α  was inhibited. Moreover, MS-275 and SAHA suppressed granulocyte chemotactic protein-2 (GCP-2, monocyte chemotactic protein-2 (MCP-2 and macrophage migration inhibitory factor (MIF in E11 cells in a concentration-dependent manner. Subsequently, E11-driven migration of THP-1 and U937 monocytes was inhibited. In summary, suppression of the p38 MAPK signaling pathway and chemotaxis appear to be important anti-rheumatic mechanisms of action of these HDAC inhibitors.

    hiring nurses with rural connections, experience and preferences. Rural nurses considered lifestyle and personal life issues when choosing a job. Concepts like time away from work, rural lifestyle, recreation opportunities, climate and social activities influenced the intention to stay on the job. Rural nurses with the most job satisfaction preferred rural lifestyles and possessed rural backgrounds. Since the generalist nurse role requires autonomy and task variability, recruiting nurses who prefer these job characteristics might enhance nurse retention. Other findings were tied to rural health and nursing theories. It is unknown why the most dissatisfied nurses had 1-3 years of experience. Similar studies with larger samples are suggested.

    Radiometric determination methods, such as alpha spectrometry require long counting times when low activities are to be determined. Mass spectrometric techniques as Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Thermal Ionisation Mass Spectrometry (TIMS) and Accelerator Mass Spectrometry (AMS) have shown several advantages compared to traditional methods when measuring long-lived radionuclides. Mass spectrometric methods for determination of very low concentrations of elemental isotopes, and thereby isotopic ratios, have been developed using a variety of ion sources. Although primarily applied to the determination of the lighter stable element isotopes and radioactive isotopes in geological studies, the techniques can equally well be applied to the measurement of activity concentrations of long-lived low-level radionuclides in various samples using 'isotope dilution' methods such as those applied in inductively coupled plasma mass spectrometry (ICP-MS). Due to the low specific activity of long-lived radionuclides, many of these are more conveniently detected using mass spectrometric techniques. Mass spectrometry also enables the individual determination of Pu-239 and Pu-240, which cannot be obtained by alpha spectrometry. Inductively Coupled Plasma Mass Spectrometry (ICP-MS) are rapidly growing techniques for the ultra-trace analytical determination of stable and long-lived isotopes and have a wide potential within environmental science, including ecosystem tracers and radio ecological studies. Such instrumentation, of course needs good radiochemical separation, to give best performance. The objectives of the project is to identify current needs and problems within low-level determination of long-lived radioisotopes by ICP-MS, to perform intercalibration and development and improvement of ICP-MS methods for the measurement of radionuclides and isotope ratios and to develop new methods based on modified separation chemistry applied to new auxiliary

    Pine (Pinus morrisonicola Hay, PM) needles have been used as folk medicine for their antihypertension and lipid-lowering effects. As supercritical fluid extraction (SFE) is considered an ideal technique for the extraction of essential oil from plant materials, the present work investigated the optimal SFE conditions and the protective effects of different resulting fractions of PM needles on lipid peroxidation and foam cell production in macrophages. Nine PM needle extracts (PME1-9) were obtained in 1%-4% yields using different SFE conditions, of which PME1 had the lowest yield (1.1%) and PME3 the highest (3.9%). PME3 exhibited lower cytotoxic effects and stronger inhibition of lipid peroxidation and formation of foam cell in RAW 264.7 macrophages than those of other PME extracts. PME3-1 purified from PME3 by column and thin layer chromatography inhibited LDL oxidation more effectively than did PME3 in a cell-free system oxidized by Cu(2+). PME3-1 dose-dependently (25-100 μg/mL) decreased conjugated diene levels and foam cell formation induced by ox-LDL. GC/MS analyses revealed that 1-docosene, neophytadiene, and methyl abietate were increased 5.2-, 1.7- and 4.3-fold in PME3-1 relative to PME3. A new hydrocarbon compound, cedrane-8,13-diol, was identified in PME3-1. Overall, the present study demonstrates the optimal extraction conditions of SFE of PM and identifies the most potent antioxidant fractions and possible active compounds in PM.

    Horticulture was shown to represent a well-being source for older adults, encompassing the physical, mental and social domains. Aim of this pilot study was to contribute to extant literature through the investigation of the quality of experience associated with horticultural versus occupational activities. A group of 11 older residents of a nursing home were involved in a crossover study with a baseline measure. Participants attended weekly horticultural and occupational sessions for two six-week cycles. Experience Sampling Method was administered before the program and after each session, to assess participants' levels of happiness, concentration, sociability, involvement, challenges and stakes, and self-satisfaction. Altogether, 332 self-report questionnaires were collected. Findings showed that participants' levels of the cognitive and motivational variables increased during both activities, but horticulture was also perceived as providing higher challenges and stakes, and improving self-satisfaction. Results can have practical implications for well-being promotion among older adults through meaningful activity engagement. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available A disconcerting proportion of Canadian nurses are physically inactive and report poor cardiovascular health. Web-based interventions incorporating feedback and group features may represent opportune, convenient, and cost-effective methods for encouraging physical activity (PA in order to improve the levels of PA and cardiovascular health of nurses. The purpose of this parallel-group randomized trial was to examine the impact of an intervention providing participants with feedback from an activity monitor coupled with a web-based individual, friend or team PA challenge, on the PA and cardiovascular health of nurses working in a cardiovascular setting.Methods: Nurses were randomly assigned in a 1:1:1 ratio to one of the following intervention “challenge” groups: (1 individual, (2 friend or (3 team. Nurses wore a Tractivity® activity monitor throughout a baseline week and 6-week intervention. Height, body mass, body fat percentage, waist circumference, resting blood pressure (BP and heart rate were assessed, and body mass index (BMI was calculated, during baseline and within 1 week post-intervention. Data were analyzed using descriptive statistics and general linear model procedures for repeated measures.Results: 76 nurses (97% female; age: 46 ± 11 years participated. Weekly moderate-to-vigorous intensity PA (MVPA changed over time (F = 4.022, df = 4.827, p = 0.002, η2 = 0.055, and was greater during intervention week 2 when compared to intervention week 6 (p = 0.011.

  12. Nursing as concrete philosophy, Part I: Risjord on nursing knowledge.

    Theodoridis, Kyriakos

    2018-04-01

    This essay addresses the problem of the essentiality of nursing knowledge and what kind of theory, if any, is essential to nursing practice. The overarching aim of the essay was to argue for the thesis that nursing may be described as a kind of philosophical activity, and, consequently, that philosophy is the kind of "theory" that is essential to nursing practice and to the nursing discipline at large. The essay consists of two papers. The present paper, Part I, is a critical examination of Mark Risjord's discussion of the problem of the theory-practice gap in his Nursing Knowledge: Practice, Science, Philosophy, from 2010. According to Risjord, the cause of the theory-practice gap originates in an erroneous conception of science (logical positivism) which had a decisive influence upon the way nursing scholars appropriated theoretical frameworks for the nursing discipline. This philosophical influence is considered in effect to have generated the theory-practice gap. In order to bridge the gap, Risjord suggests, the nursing discipline needs to adopt a standpoint epistemology conjoined with a postpositivist conception of scientific theory. In this way, a legitimate brand of nursing science may be developed and the theory-practice gap overcome. I will argue that neither Risjord's diagnosis of the problem, nor his recommended cure, may succeed in rescuing the nursing discipline from the theory-practice gap. Rather, the real cause of the theory-practice gap, I will claim, derives from an erroneous conception of nursing (not of science), namely the conception of nursing as a kind of science (roughly speaking). On my view, to overcome the gap, the nursing discipline needs to make salient the inherently philosophical character of nursing. In the second paper (Part II), I will continue the discussion of nursing knowledge and delineate the thesis of nursing as a kind of concrete philosophy. © 2017 John Wiley & Sons Ltd.

    2010-08-01

    Procedural and Emotional Religious Activity Therapy encapsulates an approach to engaging older adults with Alzheimer's disease in meaningful activities that can be performed within the parameters of their cognitive functioning. Alzheimer's disease disrupts some brain structures more than others, resulting in a disproportionate loss of certain cognitive abilities. Explicit (conscious) memory skills are disrupted first, followed by implicit (unconscious) memory skills, and lastly emotional memory. Activities relying more on implicit and emotional memory, such as specially selected religious activities, are more likely to be used by patients. Steps and caveats of using this approach are provided.

    Application of gas chromatography-mass spectrometry (GC-MS) can significantly improve trace analyses of compounds in complex matrices from natural environments compared to gas chromatography only. A GC-MS/MS technique for determination of poly-beta-hydroxybutyrate (PHB), a bacterial storage compound, has been developed and used for analysis of two soils stored for up to 319 d, fresh samples of sewage sludge, as well as a pure culture of Bacillus megaterium. Specific derivatization of beta-hydroxybutyrate (3-OH C4:0) PHB monomer units by N-tert-butyl-dimethylsilyl-N-methyltrifluoracetamide (MTBSTFA) improved chromatographic and mass spectrometric properties of the analyte. The diagnostic fragmentation scheme of the derivates tert-butyldimethylsilyl ester and ether of beta-hydroxybutyric acid (MTBSTFA-HB) essential for the PHB identification was shown. The ion trap MS was used, therefore the scan gave the best sensitivity and with MS/MS the noise decreased, so the S/N was better and also with second fragmentation the amount of ions increased compared to SIM. The detection limit for MTBSTFA-HB by GC-MS/MS was about 10(-13) g microL(-1) of injected volume, while by GC (FID) and GC-MS (scan) it was around 10(-10) g microL(-1) of injected volume. Sensitivity of GC-MS/MS measurements of PHB in arable soil and activated sludge samples was down to 10 pg of PHB g(-1) dry matter. Comparison of MTBSTFA-HB detection in natural soil sample by GC (FID), GC-MS (scan) and by GC-MS/MS demonstrated potentials and limitations of the individual measurement techniques.

  17. MS Based Metabonomics

    Want, Elizabeth J.; Metz, Thomas O.

    2010-03-01

    Metabonomics is the latest and least mature of the systems biology triad, which also includes genomics and proteomics, and has its origins in the early orthomolecular medicine work pioneered by Linus Pauling and Arthur Robinson. It was defined by Nicholson and colleagues in 1999 as the quantitative measurement of perturbations in the metabolite complement of an integrated biological system in response to internal or external stimuli, and is often used today to describe many non-global types of metabolite analyses. Applications of metabonomics are extensive and include toxicology, nutrition, pharmaceutical research and development, physiological monitoring and disease diagnosis. For example, blood samples from millions of neonates are tested routinely by mass spectrometry (MS) as a diagnostic tool for inborn errors of metabolism. The metabonome encompasses a wide range of structurally diverse metabolites; therefore, no single analytical platform will be sufficient. Specialized sample preparation and detection techniques are required, and advances in NMR and MS technologies have led to enhanced metabonome coverage, which in turn demands improved data analysis approaches. The role of MS in metabonomics is still evolving as instrumentation and software becomes more sophisticated and as researchers realize the strengths and limitations of current technology. MS offers a wide dynamic range, high sensitivity, and reproducible, quantitative analysis. These attributes are essential for addressing the challenges of metabonomics, as the range of metabolite concentrations easily exceeds nine orders of magnitude in biofluids, and the diversity of molecular species ranges from simple amino and organic acids to lipids and complex carbohydrates. Additional challenges arise in generating a comprehensive metabolite profile, downstream data processing and analysis, and structural characterization of important metabolites. A typical workflow of MS-based metabonomics is shown in Figure

  18. Antioxidant and Anti-Fatigue Activities of Phenolic Extract from the Seed Coat of Euryale ferox Salisb. and Identification of Three Phenolic Compounds by LC-ESI-MS/MS

    Full Text Available This study investigated the antioxidant potential and anti-fatigue effects of phenolics extracted from the seed coat of Euryale ferox Salisb. The in vitro antioxidant potentials, including scavenging DPPH, hydroxyl radical activities and reducing power were evaluated. Antioxidant status in vivo was analyzed by SOD, CAT, GSH-Px activities and the MDA content in liver and kidneys of D-galactose-induced aging mice. The anti-fatigue effect was evaluated using an exhaustive swimming test, along with the determination of LDH, BUN and HG content. The phenolic extract possessed notable antioxidant effects on DPPH, hydroxyl radical scavenging and reducing power. The mice which received the phenolic extract showed significant increases of SOD, CAT (except for in the kidney, GSH-Px activities, and a decrease of MDA content. The average exhaustive swimming time was obviously prolonged. Meanwhile, increase of LDH content and decrease of BUN content were observed after mice had been swimming for 15 min. The HG storage of mice was improved in the high and middle dose extract groups compared with the normal group. The contents of total phenols and gallic acid of the extract were determined. Three compounds in the extract were identified as 5,7-dihydroxy-2-(3,4,5-trihydroxyphenyl-chroman-4-one, 5,7,4-trihydroxyflavanone and buddlenol E. These results suggest that the extract of E. ferox is a promising source of natural antioxidants and anti-fatigue material for use in functional foods and medicines.

    Andrographis paniculata contains four major active diterpenoids, including andrographolide (1), 14-deoxy-11, 12-didehydroandrographolide (2), neoandrographolide (3), and 14-deoxyandrographolide (4), which exhibit differences in types and/or degrees of their pharmacological activity. Previous pharmacokinetic studies in humans reported only the parameters of compound 1 and its analytical method in human plasma. The purpose of this study was to develop a simple, sensitive, and selective liquid chromatography tandem-mass spectrometry technique for the simultaneous determination of all four major active diterpenoids in the A. paniculata product in human plasma. These four diterpenoids in plasma samples were extracted by a simple protein precipitation method with methanol and separated on a Kinetex C18 column using a gradient system with a mobile phase of acetonitrile and water. The liquid chromatography tandem-mass spectrometry was performed in the negative mode, and the multiple reaction monitoring mode was used for the quantitation. The method showed a good linearity over a wide concentration range of 2.50-500 ng/mL for 1 and over the range of 1.00-500 ng/mL for the other diterpenoids with a correlation coefficient R(2) > 0.995. The lower limit of quantification of 1 was found to be 2.50 ng/mL, while those of the other diterpenoids were 1.00 ng/mL. The intraday and interday accuracy (relative error) ranged from 0.03 % to 10.03 %, and the intraday and interday precisions (relative standard deviation) were in the range of 2.05-9.67 %. The extraction recovery (86.54-111.56 %) with a relative standard deviation of 2.78-8.61 % and the matrix effect (85.15-112.36 %) were within the acceptance criteria. Moreover, these four major active diterpenoids were stable in plasma samples at the studied storage conditions with a relative error ≤-9.79 % and a relative standard deviation ≤ 9.26 %. Hence, this present method was successfully validated

    The failure of nursing schools to integrate spiritual nursing care education into the curriculum has contributed to a lack in nurses' spiritual care ability. Developing, integrating, and testing a Spiritual Care Nursing Education strategy in an Associates of Science nursing program significantly increased the perceived spiritual care competence of student nurses. Utilizing a faculty team to develop learning activities to address critical spiritual care attributes offers a method to integrate spiritual nursing care content throughout the curriculum in ASN and BSN programs.

    Critical thinking is essential in the practice of the nurse generalist, today. Nursing faculty is frequently trying to identify teaching strategies in promoting critical thinking and engaging students in active learning. To close the gap between critical thinking and student success, a school in the south east United States implemented the use of the 'think like a nurse initiative" for incoming junior nursing students. Faculty collaborated to adopt the fundamental and essential nursing concepts for nursing students to support thinking like a nurse.

    The desire to care for people, a family history of professional health care work, and security in career choice are documented reasons for entering nursing. Reasons for leaving include workload, unsafe work environments and harassment. The relationship between these factors and the time nurses spend in the profession has not been explored. This paper reports a study with people who have left nursing, to investigate why they became a nurse, how long they stayed in nursing, and their reasons for leaving. A questionnaire was mailed to Registered Nurses currently working outside nursing, seeking respondents' reasons for entering and leaving nursing, and perceptions of the skills gained from nursing and the ease of adjustment to working in a non-nursing environment. Data analysis included descriptive statistics, exploratory and confirmatory factor analysis, correlational analysis and linear and multiple regression analysis. A model incorporating the factors 'altruistic reasons', 'default choice' and 'stepping stone' explained 36.2% of the variance in reasons for becoming a nurse. A model incorporating the factors 'legal and employer', 'external values and beliefs about nursing', 'professional practice', 'work life/home life' and 'contract requirements' explained 55.4% of the variance in reasons for leaving nursing. Forty-eight per cent of the variance in tenure in nursing practice was explained through personal characteristics of nurses (36%), reasons for becoming a nurse (7%) and reasons for leaving (6%). The reasons why nurses entered or left the profession were varied and complex. While personal characteristics accounted for a large component of tenure in nursing, those managing the nursing workforce should consider professional practice issues and the balance between work life and home life.

    Emergency nurses are expected to provide required nursing services by using their professional expertise to reduce the risk posed by disasters. Thus, emergency nurses' disaster nursing core competencies are essential for coping with disasters. The purpose of the study reported here was to identify factors influencing the disaster nursing core competencies of emergency nurses. A survey was conducted among 231 emergency nurses working in 12 hospitals in South Korea. Data were collected on disaster-related experience, attitude, knowledge, and disaster nursing core competencies by means of a questionnaire. In multiple regression analysis, disaster-related experience exerted the strongest influence on disaster nursing core competencies, followed by disaster-related knowledge. The explanatory power of these factors was 25.6%, which was statistically significant (F=12.189, pcompetencies of emergency nurses could be improved through education and training programs that enhance their disaster preparedness. The nursing profession needs to participate actively in the development of disaster nursing education and training programs. Copyright © 2017 Elsevier Inc. All rights reserved.

    Hospital administration is very important and many hospitals carry out activity-based costing under comprehensive medicine. However, nursing cost is unclear, because nursing practice is expanding both quantitatively and qualitatively and it is difficult to grasp all nursing practices, and nursing cost is calculated in many cases comprehensively. On the other hand, a nursing information system (NIS) is implemented in many hospitals in Japan and we are beginning to get nursing practical data. In this paper, we propose a nursing cost accounting model and we simulate a cost by nursing contribution using NIS data.

    Al-Kandari, Fatimah; Thomas, Deepa

    2009-12-01

    Unfinished care has a strong relationship with quality of nursing care. Most issues related to tasks incompletion arise from staffing and workload. This study was conducted to assess the workload of nurses, the nursing activities (tasks) nurses commonly performed on medical and surgical wards, elements of nursing care activities left incomplete by nurses during a shift, factors contributing to task incompletion and the relationship between staffing, demographic variables and task incompletion. Exploratory survey using a self-administered questionnaire developed from IHOC survey, USA. All full time registered nurses working on the general medical and surgical wards of five government general hospitals in Kuwait. Research assistants distributed and collected back the questionnaires. Four working days were given to participants to complete and return the questionnaires. A total of 820 questionnaires were distributed and 95% were returned. Descriptive and inferential analysis using SPSS-11. The five most frequently performed nursing activities were: administration of medications, assessing patient condition, preparing/updating nursing care plans, close patient monitoring and client health teaching. The most common nursing activities nurses were unable to complete were: comfort talk with patient and family, adequate documentation of nursing care, oral hygiene, routine catheter care and starting or changing IV fluid on time. Tasks were more complete when the nurse-patient load was less than 5. Nurses' age and educational background influenced task completion while nurses' gender had no influence on it. Increased patient loads, resulting in increased frequency of nursing tasks and non-nursing tasks, were positively correlated to incompletion of nursing activities during the shift. Emphasis should be given to maintaining the optimum nurse-patient load and decreasing the non-nursing workload of nurses to enhance the quality of nursing care.

    To determine the need for care robots among nurses and to suggest how robotic care should be prioritized in an integrated nursing care services. Korea is expected to be a super-aged society by 2030. To solve care issues with elderly inpatient caused by informal caregivers, the government introduced 'integrated nursing care services'; these are comprehensive care systems staffed by professionally trained nurses. To assist them, a care robot development project has been launched. The study applied a cross-sectional survey. In 2016, we conducted a multi-center survey involving 302 registered nurses in five hospitals including three tertiary and two secondary hospitals in Korea. The questionnaire consisted of general characteristics of nurses and their views on and extents of agreement about issues associated with robotic care. Trial center nurses and those with ≥10 years of experience reported positively on the prospects for robotic care. The top three desired primary roles for care robots were 'measuring/monitoring', 'mobility/activity' and 'safety care'. 'Reduction in workload', especially in terms of 'other nursing services' which were categorized as non-value-added nursing activities, was the most valued feature. The nurses approved of the aid by care robots but were concerned about device malfunction and interruption of rapport with patients. Care robots are expected to be effective in integrated nursing care services, particularly in 'measuring/monitoring'. Such robots should decrease nurses' workload and minimize non-value-added nursing activities efficiently. No matter how excellent care robots are, they must co-operate with and be controlled by nurses. This article is protected by copyright. All rights reserved. This article is protected by copyright.

    2004-10-01

    Quality health care is an issue of concern worldwide, and nursing can and must play a major and global role in transforming the healthcare environment. Doctorally prepared nurses are very much needed in the discipline to further develop and expand the science, as well as to prepare its future educators, scholars, leaders, and policy makers. In 1968, the Master of Science in Nursing Program was initiated in Turkey, followed by the Nursing Doctoral Education Program in 1972. Six University Schools of Nursing provide nursing doctoral education. By the graduating year of 2001, 154 students had graduated with the Doctor of Philosophy in Nursing (Ph.D.), and 206 students were enrolled in related courses. Many countries in the world are systematically building various collaborative models in their nursing doctoral education programs. Turkey would like to play an active role in creating collaborative nursing doctoral education programs with other countries. This paper centres on the structure and model of doctoral education for nurses in Turkey. It touches on doctoral programs around the world; describes in detail nursing doctoral education in Turkey, including its program structure, admission process, course units, assessment strategies and dissertation procedure; and discusses efforts to promote Turkey as a potential partner in international initiatives to improve nursing doctoral education.

  20. Gilligan's different voice: a perspective for nursing.

    Science.gov (United States)

    Cooper, M C

    1989-01-01

    This article proposes that Carol Gilligan's ethic of care provides for nursing a paradigm for moral deliberation that demonstrates compatibility with nursing's historical and philosophical traditions of relational caring and furnishes empirical support for the value of caring as a moral activity. The appropriateness of Gilligan's theory for nursing is further illustrated by an elucidation of the similarities between Gilligan's theory and nurse theorist Jean Watson's claims that caring constitutes both a necessary and a fundamental component of nursing. It is argued that Gilligan's theory of moral deliberation more faithfully reflects the nursing experience than Kohlberg's contractual, Kantian theory, which currently dominates the nursing literature.

This study used a cross-sectional design. Data were collected using self-reported questionnaires from 432 nurses in 57 units at five hospitals in South Korea. Nursing performance quality, nursing work environment, and health-promoting behaviors were measured using the Six Dimension Scale of Nursing Performance, Practice Environment Scale of the Nursing Work Index, and Health Promoting Lifestyle Profile-II, respectively. Nurses working in units with nurse managers who were characterized by better ability and by quality leadership, and who provided more support to nurses exhibited significantly greater health responsibility and physical activity. Nurses working with sufficient staffing and resources reported better stress management. Positive collegial nurse-physician relationships in units were significantly associated with more healthy eating among nurses. Nurses working in units with sufficient staffing and resources, and who had a higher level of spiritual growth and health responsibility, were more likely to perceive their nursing performance quality as being higher. To improve the quality of nursing practice, hospitals should focus on helping nurses maintain healthy lifestyles, as well as improving their working conditions in South Korea. Organizational support for adequate human resources and materials, mutual cooperation among nurses and physicians, and workplace health-promotion interventions for spiritual growth and health responsibility are needed. Organizational efforts to provide sufficient staffing and resources, boost the development of personal resources among nurses, and promote nurses' responsibility for their own health could be effective strategies for improving nursing performance quality and patient outcomes. © 2018 Sigma

    Although practical training has always been important in Nursing, it has reached a new dimension in the European Higher Education Area. This has involved adapting the syllabus, where one of the new features is considering clinical practice as an independent subject and also including the concept of competence as a result of the students' learning. The figure of the tutor becomes one of the key factors and therefore their activities and competencies must be defined. To enumerate and prioritize, by agreement, the main activities and competences by the tutor of clinical practices in the Comunidad Autónoma de Madrid should posses. METHODOLOGY. Quantitative focus, analysis by group of experts between 2010 and 2013. RESULTS. A total of 510 nurses have participated, 17 panels of experts have met and consensus has been reached on 22 competencies and 12 activities. The description of activities and competencies can be extremely useful for selecting, evaluating and developing nursing clinical practice tutors, becoming a baseline and reducing the subjectivity in the development of tutors according to the new demands of the European Higher Education Area.

  6. Why the history of nursing ethics matters.

    Science.gov (United States)

    Fowler, Marsha D

    2017-05-01

    Modern American nursing has an extensive ethical heritage literature that extends from the 1870s to 1965 when the American Nurses Association issued a policy paper that called for moving nursing education out of hospital diploma programs and into colleges and universities. One consequence of this move was the dispersion of nursing libraries and the loss of nursing ethics textbooks, as they were largely not brought over into the college libraries. In addition to approximately 100 nursing ethics textbooks, the nursing ethics heritage literature also includes hundreds of journal articles that are often made less accessible in modern databases that concentrate on the past 20 or 30 years. A second consequence of nursing's movement into colleges and universities is that ethics was no longer taught by nursing faculty, but becomes separated and placed as a discrete ethics (later bioethics) course in departments of philosophy or theology. These courses were medically identified and rarely incorporated authentic nursing content. This shift in nursing education occurs contemporaneously with the rise of the field of bioethics. Bioethics is rapidly embraced by nursing, and as it develops within nursing, it fails to incorporate the rich ethical heritage, history, and literature of nursing prior to the development of the field of bioethics. This creates a radical disjunction in nursing's ethics; a failure to more adequately explore the moral identity of nursing; the development of an ethics with a lack of fit with nursing's ethical history, literature, and theory; a neglect of nursing's ideal of service; a diminution of the scope and richness of nursing ethics as social ethics; and a loss of nursing ethical heritage of social justice activism and education. We must reclaim nursing's rich and capacious ethics heritage literature; the history of nursing ethics matters profoundly.

    Full Text Available Introduction: The nurse according to the Supreme Chamber of Nurses and Midwives is a person able to recognize the health condition of an individual or group and can create a care plan and realize it. The nurse should be primarily autonomous in making decisions about nursing care and organizing nursing care. Each competent nurse can make a proper assessment of a given situation, makes decisions efficiently and is able to quickly select the right methods of conduct. The awareness that science is always the foundation of practice is extremely important. This is how the profession of a nurse was shaped over the years. These scientific achievements greatly influence the increase of the professional nurse's prestige. Objective: The aim of the work is to gain knowledge about the perception of nursing, as a scientific discipline and nurses, by students of the nursing field. Material and methods: The study covered 100 people who are students of nursing, finishing the three-year education period. The selection of respondents was random. The study group consisted of 100% women aged 20-35, living in urban areas (51% and rural (49%. The research method used in the work is a diagnostic survey. The research tool used is a self-help questionnaire. Results: Nursing understood 16% of respondents as a profession, 3% considered them as a scientific discipline, 1% as a learning system. The vast majority of respondents (92% stated that nursing is both theoretical and practical science. The nurses' forms of activity, which contribute to the development of nursing, 73% of them reported upgrading professional qualifications, 7% writing scientific papers, 2% participation in scientific research, 1% participation in the preparation of apprentices to the profession and 1% activity in organizations unions. The most important features that should be possessed by a good nurse include: diligence and accuracy of performed procedures (25%, possessing rich knowledge in the field

    Aim: to identify the leisure activities performed in Long-Stay Institutions for the Elderly (LSIEs), registered in the city of Maringá-PR, Brazil, and to analyze the attitude of the elderly people toward leisure promoted by the institutions. METHOD: this was a descriptive and transversal study with a quantitative approach, carried out with 97 elderly people, through the establishment of the socio-demographic profile and the application of the Leisure Attitude Scale. The data was subjected to descriptive statistical analysis, association tests (chi-square or Fisher's) and Spearman's correlation. RESULTS: males, aged 80 or over, widowed, with one to eight years of study, who had a monthly income were predominant. Age group and income were significantly associated with the performance of leisure activities. The results reflected the positive attitude of the elderly people in relation to leisure activities, except in the behavioral component. CONCLUSION: the findings of this study indicate the need for further investigation into the difficulties linked to the attitude toward leisure in the behavioral component, considering aspects such as individual concepts of leisure and the health status of the elderly people.

    Full Text Available Aim: The aim of this literature review was to search for qualitative studies focusing on the concept of caring in nursing, to analyse them and to synthesize knowledge that concerns the definition of the concept of caring in nursing from the point of view of nurses and patients. Design: Review. Methods: Qualitative studies were searched for systematically in the electronic databases Academic Search Complete (EBSCO, CINAHL, Medline, Science Direct, and the Wiley Library Online, according to set criteria and defined key words for the period 1970-2015. Seven selected articles were analysed after selection of documents with the aid of a sorting chart. Results: Nurses understand caring in nursing as a relationship with patients which is characterised on the nurses' part by an individual and empathetic approach, attentiveness, experience and sensitivity. Through caring, active communication takes place, providing information which reduces anxiety and leads to the breaking down of barriers. This relationship helps protect patients' autonomy, dignity and comfort. It requires experience on the part of nurses, and it is influenced by the environment. The nurses' personal qualities (what professional knowledge, attitudes and skills they have and their availability, reliability, and emotional and physical support are important to patients. Conclusion: The concept of caring is a content specific interpersonal process which is characterized by the professional knowledge, skills, personal maturity, and interpersonal sensitivity of nurses, which result in the protection, emotional support, and the meeting of bio-psycho-social needs of patients. The results of the overview study could contribute to an explanation and understanding of the nature of caring as a fundamental feature of the discipline of nursing.

    Several studies document high levels of job satisfaction among certified nurses, but no study has examined job satisfaction and factors influencing job satisfaction of certified multiple sclerosis (MS) nurses. This study tested a theoretical model proposing that two organizational factors, colleague relationships and benefits, will predict job satisfaction. Job satisfaction was represented by four factors: autonomy, professional status, professional growth, and time efficiency. Participants included MS nurses certified for 6 months or more practicing mostly in three countries (Canada, Great Britain, and the United States) who anonymously completed the Misener Nurse Practitioner Job Satisfaction Scale, an overall job satisfaction rating, and demographic information. Findings indicate that colleague relationships and benefits significantly estimated organization structure and that autonomy, professional status, professional growth, and time efficiency significantly estimated job satisfaction; furthermore, organization factors such as colleague relationships and benefits significantly predict job satisfaction. Among the countries, several statistically significant differences were observed between job satisfaction factors as well as items in both organization and job satisfaction subscales. Average factor scores among the countries were mostly rated satisfactory. The International Organization of Multiple Sclerosis Nurses Executive Board plans to use the study findings to see how it needs to focus efforts as an organization toward enhancing and standardizing MS care and develop MS nurse professionalism worldwide.

    Cognitive behavioural therapy (CBT) effectively reduces fatigue directly following treatment in patients with Multiple Sclerosis (MS), but little is known about the process of change during and after CBT. Additional analysis of a randomized clinical trial. To investigate which psychological factors mediate change in fatigue during and after CBT. TREFAMS-CBT studied the effectiveness of a 16-week CBT treatment for MS-related fatigue. Ninety-one patients were randomized (44 to CBT, 47 to the MS-nurse consultations). Mediation during CBT treatment was studied using assessments at baseline, 8 and 16weeks. Mediation of the change in fatigue from post-treatment to follow-up was studied separately using assessments at 16, 26 and 52weeks. Proposed mediators were: changes in illness cognitions, general self-efficacy, coping styles, daytime sleepiness, concentration and physical activity, fear of disease progression, fatigue perceptions, depression and physical functioning. Mediators were separately analysed according to the product-of-coefficients approach. Confidence intervals were calculated with a bootstrap procedure. During treatment the decrease in fatigue brought on by CBT was mediated by improved fatigue perceptions, increased physical activity, less sleepiness, less helplessness, and improved physical functioning. Post-treatment increases in fatigue levels were mediated by reduced physical activity, reduced concentration, and increased sleepiness. These results suggests that focusing on improving fatigue perceptions, perceived physical activity, daytime sleepiness, helplessness, and physical functioning may further improve the effectiveness of CBT for fatigue in patients with MS. Maintenance of treatment effects may be obtained by focusing on improving physical activity, concentration and sleepiness. Copyright © 2018 Elsevier Inc. All rights reserved.

    This paper describes the educational activity of a group of 149 nurse teachers and administrators following completion of the nursing education and nursing administration certificate courses of the University of Edinburgh (1958-1975). The data were obtained by a postal questionnaire and three particular types of courses reported by the respondents are discussed. Emphasis is given to the analysis involving degree courses as this was a prominent educational activity, especially among nurse teachers. The conclusion discusses the potential of an all graduate nurse teacher group and suggests some implications for the nursing profession.

    The European Charcot Foundation supported the development of a set of surveys to understand current practice patterns for the diagnosis and management of multiple sclerosis (MS) in Europe. Part 2 of the report summarizes survey results related to secondary progressive MS (SPMS), primary progressive MS (PPMS), pregnancy, paediatric MS and overall patient management. A steering committee of MS neurologists developed case- and practice-based questions for two sequential surveys distributed to MS neurologists throughout Europe. Respondents generally favoured changing rather than stopping disease-modifying treatment (DMT) in patients transitioning from relapsing-remitting MS to SPMS, particularly with active disease. Respondents would not initiate DMT in patients with typical PPMS symptoms, although the presence of ≥1 spinal cord or brain gadolinium-enhancing lesion might affect that decision. For patients considering pregnancy, respondents were equally divided on whether to stop treatment before or after conception. Respondents strongly favoured starting DMT in paediatric MS with active disease; recommended treatments included interferon, glatiramer acetate and, in John Cunningham virus negative patients, natalizumab. Additional results regarding practice-based questions and management are summarized. Results of part 2 of the survey of diagnostic and treatment practices for MS in Europe largely mirror results for part 1, with neurologists in general agreement about the treatment and management of SPMS, PPMS, pregnancy and paediatric MS as well as the general management of MS. However, there are also many areas of disagreement, indicating the need for evidence-based recommendations and/or guidelines. © 2018 EAN.

    Chronic pain is likely to lead to depressive symptoms, but the nature of this relationship is not completely clear. The aim of the present study is to analyze the role of activity restriction in the pain-depression relationship in older people, and to test the hypothesis that this role is more relevant in community-dwelling older people than in nursing home residents. Depressive symptoms, pain intensity, and activity restriction were measured in a sample of 208 older adults with osteoarthritis, 102 living in nursing homes (NH), and 106 in the community. Analyses were carried out using moderation and moderated mediation analyses approach, treating activity restriction as a confounder. RESULTS showed a significant confounding effect of activity restriction, interaction effect between pain intensity and activity restriction on depression, and modifying effect of pain intensity on depression by adding activity restriction into the model. These results suggest a potential mediating and moderating effects of activity restriction. Moreover, analyses suggest that, surprisingly, the strength of the mediation could be higher in nursing homes. Overall, it may be that what is really important to emotional well-being is not so much pain itself, but rather the way in which the pain alters older people's lives. The greater strength of the mediation in NH might be understood within the scope of self-determination theory. Generally speaking, the NH context has been considered as a coercive setting, promoting non-autonomous orientation. In this context, when events are objectively coercive, people may lack perceived autonomy and hence be at greater risk of depression.

    To examine the amount of support being provided by nurses to women during childbirth and factors that influence the provision of support. Exploratory, descriptive. Work sampling method was used to determine the percentage of time nurses spend in supportive care activities. Twelve nurses were observed over six nonconsecutive day shifts on a birthing unit of a Canadian teaching hospital in Quebec. A total of 404 observations were made. Nurses were also interviewed to determine their perceptions of what constitutes supportive nursing care and the factors that facilitate or inhibit the provision of this care. Nurses spent only 12.4% of their total time providing supportive care to laboring women. Interviews with nurses suggested that perceptions of the components of supportive care were comparable to this study's operational definition of support, namely: physical, emotional, and instructional/informational support and advocacy. Barriers to providing support identified by nurses included lack of time and insufficient staff. However, further content analysis of the interview data revealed that healthcare providers had a pervasive sense of control over laboring women and their partners. Although nursing support has been identified as an important aspect of nursing care in childbirth, this study demonstrated an incongruity between what nurses perceived as being supportive care and the amount of support that was actually provided. Barriers to the provision of supportive care in the practice setting as well as suggestions for its enhancement are discussed.

  7. Mapping Nursing Pathways

    Full Text Available Articulated education pathways between the vocational education training sector and universities provide opportunities for students wishing to progress to higher qualifications. Enrolled nurses seeking to advance their career in nursing can choose to enter baccalaureate degree programs through such alternative entry routes. Awarding of credit for prior studies is dependent on accurate assessment of the existing qualification against that which is sought. This study employed a modified Delphi method to inform the development of an evidence-based, structured approach to mapping the pathway from the nationally consistent training package of the Diploma of Nursing to the diversity of baccalaureate nursing programs across Australia. The findings of this study reflect the practical nature of the role of the enrolled nurse, particularly the greater emphasis placed on direct care activities as opposed to those related to professional development and the generation and use of evidence. These findings provide a valuable summative overview of the relationship between the Diploma of Nursing and the expectations of the registered nurse role.

    A simple and efficient bioanalytical method for simultaneous determination of phenobarbital (PB), phenytoin (PHT), carbamazepine (CBZ), and its active metabolite carbamazepine 10,11-epoxide (CBZE) in human plasma using online solid phase extraction (SPE)-liquid chromatography (LC) coupled with high resolution mass spectrum (HRMS) under targeted MS/MS (t-MS(2)) analysis mode has been developed. The procedure integrated an automated sample clean-up of human plasma by Oasis®HLB SPE cartridge, a separation by ZORBAX SB-C18 analysis column, and a quantification by Q-Exactive Hybrid Quadrupole-Orbitrap. The total running time was 13min. The lower limit of quantification (LLOQ) of PB, PHT, CBZ, and CBZE were 0.008, 0.008, 0.0016 and 0.0016μgmL(-1) respectively and the linearities were in the range of 0.008-2.500, 0.008-2.500, 0.0016-0.500 and 0.0016-0.500μgmL(-1) respectively. The mean recovery was between 91.82% and 108.27% and the matrix effect was between 93.29% and 102.09%. The relative standard deviations of interday and intraday were less than 6.41%. The method has been successfully applied in therapeutic drug monitoring (TDM) of four Chinese epilepsy patients. This fully automated, simple, sensitive and reliable online-SPE-LC-HRMS/MS method serves well for TDM of PB, PHT, CBZ and CBZE at clinics for either single or combination treatment.

    Nurses and nursing students are exposed to workplace violence. To compare the characteristics and effects of violence in nursing students and nurses in order to assess the phenomenon and take preventive action. A retrospective survey was conducted in three Italian university schools of nursing. At the end of a lecture, 346 of 349 students agreed to fill out a questionnaire that included domains on violence, mental health, job stress, and organizational justice. This group was compared with 275 nurses from a general hospital (94.2% participation rate). The prevalence of subjects reporting at least one upsetting episode of physical or verbal violence during their lifetime activity in clinical settings was 43% in nurses and 34% in nursing students. Nurses reported more physical assaults (odds ratio [OR] 2.89, 95% confidence interval [CI] 1.35-6.18), threats (OR 2.84, 95% CI 1.39-5.79), and sexual harassment (OR 2.3, 95% CI 1.15-5.54) during the previous 12 months than students. Nurses were mostly assaulted or harassed by patients or their relatives and friends ("external" violence), whereas students often reported verbal and also physical violence on the part of colleagues, staff, and others, including teachers, doctors, and supervisors ("internal" violence). Verbal violence was associated with high levels of psychological problems, as measured by the 12-item version of the General Health Questionnaire, in both students and nurses. Verbal violence was also associated with high job strain, low social support, and low organizational justice, but only among nursing students. Preventive action is urgently needed to control patient-to-worker and worker-to-worker violence in clinical settings. Not only nurses, but also nursing students, would benefit from multilevel programs of violence prevention. © 2011 Sigma Theta Tau International.

    Animal-assisted activities (AAA) and animal-assisted therapy (AAT) programs are increasing in popularity, but current programs vary in their safety and health policies. Veterinarians can have an important role in ensuring the safety of both the animals and humans involved, but it is unclear how best to educate veterinary students to serve effectively in this role. Therefore, the goal of this study was to assess the knowledge gaps and perceptions of first-year veterinary students on health and safety aspects of AAA/AAT programs by administering a survey. This information could then guide future educational training in veterinary schools to address the knowledge gaps in this area. Formal education during the veterinary curriculum had not yet been provided to these students on AAA/AAT before the survey. Of 98 first-year veterinary students, 91 completed the survey. When asked about policies on visiting animals, 58% of students responded that nursing homes are required to have a policy and 67% responded that hospitals are required to have one. Three quarters of students reported that veterinarians, animal handlers, and facilities should share the responsibility for ensuring safe human-animal interaction in AAA/AAT programs. Most (82%) of the students responded that all or most national and local therapy animal groups prohibit animals that consume raw meat diets from participating in AAA/AAT programs. The results of this survey will help veterinary schools better identify knowledge gaps that can be addressed in veterinary curricula so future veterinarians will be equipped to provide appropriate public health information regarding AAA/AAT programs.

    White, Katherine M; Wise, Susi E; Young, Ross McD; Hyde, Melissa K

    A qualitative study explored beliefs about active voluntary euthanasia (AVE) in a sample (N = 18) of medical practitioners and nurses from Australia, where AVE is not currently legal. Four behaviors relating to AVE emerged during the interviews: requesting euthanasia for oneself, legalizing AVE, administering AVE to patients if it were legalized, and discussing AVE with patients if they request it. Using thematic analysis, interviews were analyzed for beliefs related to advantages and disadvantages of performing these AVE behaviors. Medical practitioners and nurses identified a number of similar benefits for performing the AVE-related behaviors, both for themselves personally and as health professionals. Benefits also included a consideration of the positive impact for patients, their families, and the health care system. Disadvantages across behaviors focused on the potential conflict between those parties involved in the decision making process, as well as conflict between one's own personal and professional values.

    This study assessed the characteristics of nursing students currently enrolled in nursing education programs, how students finance their nursing education, their plans for clinical practice and graduate education, and the rewards and difficulties of being a nursing student. Data are from a survey administered to a national sample of 496 nursing students. The students relied on financial aid and personal savings and earnings to finance their education. Parents, institutional scholarships, and government loans are also important sources, but less than 15% of the students took out bank loans. Nearly one quarter of the students, particularly younger and minority students, plan to enroll in graduate school immediately after graduation and most want to become advanced nursing practitioners. Most of the nursing students (88%) are satisfied with their nursing education and nearly all (95%) provided written answers to two open-ended questions. Comments collapsed into three major categories reflecting the rewards (helping others, status, and job security) and three categories reflecting the difficulties (problems with balancing demands, quality of nursing education, and the admissions process) of being a nursing student. Implications for public policymaking center on expanding the capacity of nursing education programs, whereas schools themselves should focus on addressing the financial needs of students, helping them strike a balance among their school, work, and personal/family responsibilities and modifying certain aspects of the curriculum.

    Implementing family system nursing in clinical settings is on the rise. However, little is known about the impact of graduate school education as well as continuing education in family systems nursing (FSN) on nurses' perceptions of their family nursing practice. To evaluate the level of nursing education, having taken a continuing hospital educational course in family system nursing (FN-ETI programme), and the impact of job characteristics on nurses' perceptions of their family nursing practice skills. Participants were 436 nurses with either a BSc degree or graduate degree in nursing. The Job Demand, Control and Support model guided the study (R. Karasek and T. Theorell, 1992, Healthy Work: Stress, Productivity, and the Reconstruction of Working Life, Basic Books, New York, NY). Scores for the characteristics of job demands and job control were created to categorise participants into four job types: high strain (high demand, low control), passive (low demand, low control), low strain (low demand, high control) and active (high demand, high control). Nurses with a graduate education who had taken the FN-ETI programme scored significantly higher on the Family Nursing Practice Scale than nurses with an undergraduate education. Nurses who were characterised as low strain or active scored significantly higher on the Family Nursing Practice Scale than the nurses who were characterised as high strain. Further, the interaction of education by job type was significant regarding family nursing practice skills. Hierarchical regression revealed 25% of the variance in family nursing practice skills was explained by job control, family policy on the unit, graduate education and employment on the following divisions: Maternal-Child, Emergency, Mental Health or Internal Medicine. Graduate education plus continuing education in FSN can offer nurses increased job opportunities more control over one's work as well as increased skills working with families in clinical settings.

    Full Text Available The volatile components of Citrus aurantium L. flowers were characterized by GC-MS with two different extraction techniques, hydrodistillation (HD and ultrasonic-assisted headspace solid phase microextraction (UA-HS-SPME. In the SPME method, the volatile components of the samples, irradiated by ultrasonic radiation, were collected on a polydimethyl siloxane (PDMS commercial fiber as well as some manually prepared nanoporous fibers from the samples headspace. To reach the better results, the extraction conditions were carefully optimized for the PDMS fiber. Under the optimized conditions (i.e. sonication time 15 min, extraction time 30 min and extraction temperature 55 ºC, 54 compounds were identified by the UA-HS-SPME-GC/MS method. The essential oil components of Citrus aurantium L. flower samples from two different regions of Iran and new and old samples from the same region were compared to one another. The major components identified for the samples with both the SPME and HD methods were linalool, linalyl acetate, limonene, β-myrcene, geranyl acetate, and neryl acetate, respectively. However, a substantial variation in the percentages of the components was identified for different samples and different extraction methods. The antimicrobial activities of the oil were also examined against six standard bacteria. There was some activity against Enterococcus fecalis, Escherichia coli, and Bacillus cereus, indicating important biological activities of the oil.

    To compare the cost-effectiveness of three types of follow-up for outpatients with stable low-activity rheumatoid arthritis (RA). In total, 287 patients were randomized to either planned rheumatologist consultations, shared care without planned consultations, or planned nurse consultations. Effectiveness measures included disease activity (Disease Activity Score based on 28 joint counts and C-reactive protein, DAS28-CRP), functional status (Health Assessment Questionnaire, HAQ), and health-related quality of life (EuroQol EQ-5D). Cost measures included activities in outpatient clinics and general practice, prescription and non-prescription medicine, dietary supplements, other health-care resources, and complementary and alternative care. Measures of effectiveness and costs were collected by self-reported questionnaires at inclusion and after 12 and 24 months. Incremental cost-effectiveness rates (ICERs) were estimated in comparison with rheumatologist consultations. Changes in disease activity, functional status, and health-related quality of life were not statistically significantly different for the three groups, although the mean scores were better for the shared care and nurse care groups compared with the rheumatologist group. Shared care and nurse care were non-significantly less costly than rheumatologist care. As both shared care and nurse care were associated with slightly better EQ-5D improvements and lower costs, they dominated rheumatologist care. At EUR 10,000 per quality-adjusted life year (QALY) threshold, shared care and nurse care were cost-effective with more than 90% probability. Nurse care was cost-effective in comparison with shared care with 75% probability. Shared care and nurse care seem to cost less but provide broadly similar health outcomes compared with rheumatologist outpatient care. However, it is still uncertain whether nurse care and shared care are cost-effective in comparison with rheumatologist outpatient care.

    Calls for improved conditions in nursing homes have pointed to the importance of optimizing the levels and skills of care providers. Understanding the work of care providers will help to determine if staff are being used to their full potential and if opportunities exist for improved efficiencies. To explore the activities of care providers in different nursing homes and to identify if variations exist within and across homes and shifts. A multi-centre cross-sectional observational work flow study was conducted in seven different nursing homes sites in one Canadian province. Data were collected by a research assistant who conducted 368 h of observation. The research assistant collected data by following an identical route in each site and recording observations on staff activities. Findings indicate staff activities vary across roles, sites and shifts. Licensed practical nurses (nursing assistants) have the greatest variation in their role while registered nurses have the least amount of variability. In some sites both registered nurses and licensed practical nurses perform activities that may be safely delegated to others. Care providers spend as much as 53.7% of their time engaged in non-value added activities. There may be opportunities for registered nurses and licensed practical nurses to delegate some of their activities to non-regulated workers. The time care providers spend in non-value activities suggest there may be opportunities to improve efficiencies within the nursing home setting. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available The study aimed at analyzing the metabolite profile of Nardostachys jatamansi using RP-HPLC, GC-MS and also its antioxidant, biomolecule protective and cytoprotective properties. The 70% ethanolic extract of Nardostachys jatamansi (NJE showed the presence of polyphenols and flavonoids (gallic acid, catechin, chlorogenic acid, homovanillin, epicatechin, rutin hydrate and quercetin-3-rhamnoside analyzed by RP-HPLC, whereas hexane extract revealed an array of metabolites (fatty acids, sesquiterpenes, alkane hydrocarbons and esters by GC-MS analysis. The antioxidant assays showed the enhanced potency of NJE with a half maximal inhibitory concentration (IC50 value of 222.22 ± 7.4 μg/mL for 2,2-diphenyl-1-picrylhydrazyl (DPPH, 13.90 ± 0.5 μg/mL for 2,2′-azino-bis(3-ethyl benzothiazoline-6-sulfonic acid diammonium salt (ABTS, 113.81 ± 4.2 μg/mL for superoxide, 948 ± 21.1 μg/mL for metal chelating and 12.3 ± 0.43 mg FeSO4 equivalent/g of extract for ferric reducing antioxidant power assays and was more potent than hexane extract. NJE effectively inhibited 2,2′-azobis(2-methylpropionamidine dihydrochloride (AAPH-induced oxidation of biomolecules analyzed by pBR322 plasmid DNA damage, protein oxidation of bovine serum albumin and lipid peroxidation assays. The observed effects might be due to the high content of polyphenols, 53.06 ± 2.2 mg gallic acid equivalents/g, and flavonoids, 25.303 ± 0.9 mg catechin equivalents/g, of NJE compared to the hexane fraction. Additionally, the extract abrogated the protein, carbonyl, and ROS formation, and NJE showed cytotoxicity in SH-SY5Y neuronal cells above 75 μg/mL. Thus, the study suggests that the herb unequivocally is a potential source of antioxidants and could aid in alleviating oxidative stress-mediated disorders.

    Two insect colonies of Elasmopalpus lignosellus were reared in our laboratory, the first being initiated from pupae obtained from a cornfield in the region of Sete Lagoas, Minas Gerais and the second from a cornfield in the region of Goiânia, Goiás. From the two colonies, two extracts were prepared from the pheromone glands of virgin E. lignosellus females. The extract obtained from the first colony was designated as extract 1 while the extract obtained from the second colony was designated as extract 2. Extract 1 was analyzed by gas chromatography-mass spectrometry (GC-MS) with (Z)-9-hexadecenyl acetate [(Z)-9-HDA] and (Z)-11-hexadecenyl acetate [(Z)-11-HDA] being identified and confirmed by the formation of DMDS derivatives. In addition, a third acetate, which could be either (E)-8-hexadecenyl acetate [(E)-8-HDA] or (E)-9-hexadecenyl acetate [(E)-9-HDA] was detected by GC-MS. Extract 2 was analyzed by gas chromatography (GC) and gas chromatography-electroannetography (GC-EAD) revealing the presence of (Z)-11-HDA and (Z)-9-TDA. In addition, the same compounds elicited a response with the E. lignosellus male antenna obtained from the second insect colony. Electroantennography (EAG) screening with the male E. lignosellus antenna (obtained from the second insect colony) was conducted with the 23 possible tetradecenyl acetates (TDA) and 22 hexadecenyl acetates (HDA) as standards. Out of the 23 TDA isomers evaluated, only (Z)-9-TDA elicited a response and out of the 22 HDA [(Z) and (E) isomers gamma2 to delta13] evaluated only (Z)-11-HDA elicited a response. The acetate compositions of two extracts obtained from insects originating from the two states (Minas Gerais and Goiás) of Brazil were different from one another as well as from that obtained from insects in Tifton, GA, USA. The bioactivity data (GC-EAD) of the extract 2 differed from those reported for the Tifton, GA, USA population. These data suggest polymorphism in relation to the insect populations found in

    School officials and nurses play an important role in facilitating asthma management in schools. Little is known about their perspectives on in-school asthma management and barriers to physical activity (PA) at school. The goal of this study is to explore school officials' and nurses' perspectives on asthma care and barriers to PA in children with asthma attending New York City schools. We conducted qualitative, semistructured interviews with 10 principals, 3 assistant principals, and 9 nurses in 10 Bronx, New York elementary schools. Sampling continued until thematic saturation was reached. Interviews were recorded, transcribed, and coded for common themes. The thematic and content review was subsequently used to analyze interview data. Emerging themes were discussed and agreed on by both investigators. Three main categories arose from the analysis: (1) procedures and policies around asthma management in school, (2) barriers to effective medication administration in school, and (3) barriers to PA in children with asthma. Participants identified gaps to in-school asthma management and barriers to PA participation: ineffective ways of identifying students with asthma; lack of written procedures for asthma management; difficulty in meeting the administrative requirements to administer asthma medication; lack of knowledge and training on asthma management for the parents, students, and school staff; parental limitation of children's PA; and schools not meeting the state physical education requirement. Our findings suggest the need for policy reform on asthma management and PA in urban schools and should be considered in the design of future interventions.

    This study describes the route followed by nursing in Brazil, through the foundation of nursing organizations and the emergence of nursing leaders and pioneers. To present the origins of modern nursing in Brazil, identifying the main nurse-leaders and analysing their performance for the creation and consolidation of the nursing organizations. It is a historical and social study with descriptive approach, to describe the process of Brazilian nursing professionalization and leadership through a literature review. The oldest nursing organization is the Brazilian Nursing Association that holds scientific and cultural activities. There are also nurses' unions and nursing specialty associations, such as the Brazilian Academy for the History of Nursing, and the Federal Nursing Council. The latter has compulsory membership for controlling nursing services according to the qualifications of the personnel. The very first school for nurses in the Nightingale system was created in São Paulo, 1894, at the Samaritan Hospital, and by the government in 1923, in Rio de Janeiro, for which American nurses, led by Ethel Parsons, sponsored by the Rockefeller Foundation, were essential for the creation of the Anna Nery Nursing School, still in operation within a federal university. Some nurses pioneered these works such as Edith Fraenkel, Maria Rosa Pinheiro, Amalia Carvalho and others. The work done by nursing leaders has brought to the profession a better status and made it more recognized by the society. © 2014 International Council of Nurses.

    In clinical nursing courses, students are trained to identify the status of the target patients. The mastery of such ability and skills is very important since patients frequently need to be cared for immediately. In this pilot study, a repertory grid-oriented clinical mobile learning system is developed for a nursing training program. With the assistance of the mobile learning system, the nursing school students are able to learn in an authentic learning scenario, in which they can physically face the target patients, with the personal guidance and supplementary materials from the learning system to support them. To show the effectiveness of this innovative approach, an experiment has been conducted on the "respiratory system" unit of a nursing course. The experimental results show that the innovative approach is helpful to students in improving their learning achievements. Moreover, from the questionnaire surveys, it was found that most students showed favorable attitudes toward the usage of the mobile learning system and their participation in the training program.

    2016-02-01

    An inherent part of nurses' work is to handle nurse calls that often cause challenging interruptions to ongoing activities. In situations when nurses are interrupted by a nurse call, they need to decide whether to continue focusing on the task at hand or to abort and respond to the nurse call. The difficult decision is often influenced by a number of factors and can have implications for patient safety and quality of care. The study investigates how technology could be designed to support nurses' handling of nurse calls by allowing patients to communicate a more contextualised message revealing their intention to the nurse when issuing a nurse call. Through a qualitative methodology employing a scenario-based design approach, three different nurse call system concepts are evaluated by nurses from different departments of a Norwegian university hospital. Nurses find the uncertainty of not knowing the reason behind a nurse call stressful in situations where they are required to prioritise either the calling patient or a patient they are currently nursing. Providing information about a patient's intention behind a nurse call influences the nurse's decision to various degrees depending on the situation in which they find themselves and the information that is communicated. The nurses' reflections suggested that the message communicated should be designed to contain neither too little nor too much information about the patient's needs. A nurse call system that allows nurses to discern the reason behind a nurse call allows them to make a more accurate decision and relieves stress. In particular, the information communicated would reduce uncertainty and lessen nurses' dependence on other factors in their decision. The design of such a system should, however, carefully consider the needs of the department in which it is deployed. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  13. Treatment and disease management of multiple sclerosis patients: A review for nurse practitioners.

    2017-10-01

    This review discusses the role of the nurse practitioner (NP) in evaluating the clinical effects, potential side effects, and monitoring requirements for treatment options in multiple sclerosis (MS) and provides guidance on how to help patients understand these issues. A literature search was conducted on PubMed to identify publications on monitoring and disease management of MS patients. Additional resources included drug information web sites and package inserts. NPs play an active role in the management of MS patients via effective monitoring and communication throughout the patient's treatment regimen and disease course. In the shared decision-making model of MS treatment, NPs ensure that patients understand the implications of their disease-modifying therapies (DMTs). As patients move through treatments during the course of their disease, the importance of this role increases, and it is critical that NPs follow the guidelines in each medication's product label and take into account any potential lingering effects of prior medications. It is critical for NPs to promote patient adherence, to ensure that patients understand treatment side effects and monitoring requirements, and to take sequencing and reversibility implications of DMTs into account when making clinical decisions. ©2017 American Association of Nurse Practitioners.

    The present study was designed to investigate the bioactive constituents of Xanthoceras sorbifolia in terms of amounts and their antioxidant, DNA scission protection, and α-glucosidase inhibitory activities. Simultaneous quantification of 10 X. sorbifolia constituents was carried out by a newly established ultra-high performance liquid chromatography-quadrupole mass spectrometry method (UHPLC-MS). The antioxidant activities were evaluated by measuring DPPH radical scavenging and DNA scission protective activities. The α-glucosidase inhibitory activities were investigated by using an assay with α-glucosidase from Bacillus Stearothermophilus and disaccharidases from mouse intestine. We found that the wood of X. sorbifolia was rich in phenolic compounds with the contents of catechin, epicatechin, myricetin, and dihydromyricetin being 0.12-0.19, 1.94-2.16, 0.77-0.91, and 6.76-7.89 mg·g(-1), respectively. The four constituents strongly scavenged DPPH radicals (with EC50 being 4.2, 3.8 and 5.7 μg·mL(-1), respectively) and remarkably protected peroxyl radical-induced DNA strand scission (92.10%, 94.66%, 75.44% and 89.95% of protection, respectively, at a concentration of 10 μmol·L(-1)). A dimeric flavan 3-ol, epigallocatechin-(4β→8, 2β→O-7)-epicatechin potently inhibited α-glucosidase with an IC50 value being as low as 1.2 μg·mL(-1). The established UHPLC-MS method could serve as a quality control tool for X. sorbifolia. In conclusion, the high contents of antioxidant and α-glucosidase inhibitory constituents in X. sorbifolia support its use as complementation of other therapeutic agents for metabolic disorders, such as diabetes and hypertension.

    Social networking is popular online activity; however, like many activities on the internet, there are some privacy risks and concerns associated with its use. Recently, an increasing number of nurses have been censured or asked to appear before regulatory or registering authorities for unprofessional behaviour on social media sites. Problem behaviours identified include: inappropriate content and postings, crossing professional boundaries and breaching patient privacy and confidentiality. This discussion paper aims to give the nursing profession an understanding of how their online behaviour can impact on their professionalism, and how they can avoid problematic situations when using social media (Facebook). This exploratory discussion paper will inform a study researching nurses' online behaviour. Social media is here to stay and nurses need to navigate the complexities of the boundaries between the personal and the professional. Nurses need to learn to balance the growing usefulness of social media, with the legalities and etiquette of the online environment.

    The purpose of chapter 3 is to provide a conceptual framework for understanding marketing. Although it is often considered to be, marketing is not really a new activity for nursing organizations. What is perhaps new to most nursing organizations is the conduct of marketing activities as a series of interrelated events that are part of a strategic marketing process. The increasingly volatile nursing environment requires a comprehensive approach to marketing. This chapter presents definitions of marketing, the marketing mix, the characteristics of nonprofit marketing, the relationship of strategic planning and strategic marketing, portfolio analysis, and a detailed description of the strategic marketing process. While this chapter focuses on marketing concepts, essential components, and presentation of the strategic marketing process, chapter 4 presents specific methods and techniques for implementing the strategic marketing process.

    This study was designed to evaluate antimicrobial activity and chemical composition of four different plant essential oils i.e. Ginger oil (GiO), Black seed oil (BSO), Oregano oil (OO) and Rose oil (RO) against different bacterial and fungal strains. Anti-microbial activities of selected essential oils were determined by the microbiological technique using Agar well diffusion assay. After in vitro study, most of the essential oils showed antimicrobial activity against all the selected pathogens. Among all the tested oils, GiO showed strong antimicrobial activity. GiO showed highest antimicrobial activity against Shigella (119.79%), Enteococcus hirae (110.61%) and Escherichia coli (106.02%), when compared with the tetracycline (50 µg/mL) activity. However, Antifungal activity of GiO was found to be present against Candida albicans and Aspergilluas flavus , when compared with clotrimazole (50 µg/mL) activity. Among all the selected bacteria, BSO showed maximum antimicrobial activity against the E. coli followed by Citrobacter freundii. Moreover, BSO had highest zone of inhibition against the C. ablicans (33.58%). OO indicated that, Shigella had the highest sensitivity (12.6 ± 0.58, 131.25%), followed by E. hirae (19.1 ± 0.61, 96.46%) and Salmonella typhi (15.2 ± 0.27, 83.06%) when compared with tetracycline activity. OO showed poor sensitivity against all the selected fungal strains. Furthermore, Gas Chromatography analysis revealed that, Gingerol (10.86%) was the chief chemical constituents found in GiO followed by α -Sesquiphellandrene (6.29%), Zingiberene (5.88%). While, BSO, OO and RO had higher percentage of p-Cymene (6.90%), Carvacrol (15.87%) and Citronellol (8.07%) respectively. The results exhibited that the essential oils used for this study was the richest source for antimicrobial activity which indicates the presence of broad spectrum antimicrobial compounds in these essential oils. Hence, essential oils and their components can be

    Full Text Available BACKGROUND: Annualized relapse rates (ARR in the placebo cohorts of phase-3 randomized controlled trials (RCT of new treatments for relapsing remitting multiple sclerosis (RRMS have decreased substantially during the last two decades. The causes of these changes are not clear. We consider a better understanding of this phenomenon essential for valuing the effects of new drugs and by designing new trials. OBJECTIVES: To identify predictive factors of on-study ARR in early and recent MS trials. METHODS: ARR, rate of relapse-free patients, trial start dates, baseline demographics, relapse definitions and the use of McDonald criteria were retrieved by literature research of the placebo cohorts from RRMS phase-3 trials. Predictors were estimated by univariate and multivariate regression analyses and random-effects meta-regression. In addition, regression models were calculated by the Sylvia Lawry Centre's (SLC, including individual case data from clinical trials performed until 2000. The most reliable meta-analytic results can be gained from pooled individual case data. In lack of this, random-effects meta-analyses are recommended. RESULTS: Data from 12 published and one unpublished trial show a decrease of ARR from 1988 to 2012 (adjR(2 = 0.807, p<0.0001. Regression models identified McDonald criteria followed by baseline mean age and the pre-study relapse rate as predictors of the ARR. The pooled individual case data (n = 505 confirmed a decrease of ARR over time. The pre-study relapse rate was the best predictor for on-study relapses. Lacking individual case data after implementation of the McDonald criteria excludes a direct comparison concerning McDonald criteria. CONCLUSION: Pre-study relapse rate was the best predictor for on-study relapse rate but failed to explain the decrease of the ARR over time alone. Higher age at baseline and the implementation of McDonald criteria were associated as well with a lowered relapse rate in the random

    Toxicological screening is the analysis of biological samples to detect and identify unknown compounds. The high selectivity and sensitivity of liquid chromatography (LC) coupled to mass spectrometry (MS) or tandem mass spectrometry (MS/MS) technology provide an attractive alternative to the current methods (LC-UV, GC/MS, etc.). For these reasons, an increasing number of applications are being published. This paper is a brief overview of LC-MS(/MS) screening methods developed for clinical toxicology in recent years. Various sample treatments, chromatographic separations and detection by mass spectrometry can be combined to obtain screening methods adapted to the constraints and needs of clinical toxicology laboratories. Currently the techniques are in the hands of specialists, mainly in academic institutions. However, the evolution in technology should allow application of these techniques as a tool in toxicology laboratories, thus allowing a more widespread exploitation of their potential.
