Published: May 2019

AbstractThere is widespread recognition that workplace stress can have profound negative impacts on nurses’ well‐being and practice. Resilience is a process of positive adaptation to stress and adversity. This study aimed to describe mental health nurses’ most challenging workplace stressors, and their psychological well‐being, workplace resilience, and level of caring behaviours, explore the relationships between these factors, and describe differences in workplace resilience for sociodemographic characteristics. In a descriptive correlational study using convenience sampling, data were collected from N = 498 nurses working in mental health roles or settings in Victoria Australia via an online cross‐sectional survey. Key findings included weak to strong (r = 0.301 to r = 0.750) positive relationships between workplace resilience with psychological well‐being across all stressor categories (consumer/carer; colleague; organizational role; and organizational service). Psychological well‐being was moderately high, but lower for nurses indicating consumer/carer‐related stressors as their most stressful challenge. There were weak to moderate (r = 0.306 to r = 0.549) positive relationships between workplace resilience and psychological well‐being, and no relationship between resilience and caring behaviours. Workplace resilience was lower (P < 0.05) for less experienced nurses compared with those with >5 years’ experience, and lower for younger nurses compared with those aged ≥40 years. To improve their resilience and prevent psychological distress, there is prime opportunity to support nursing students with well‐being and resilience‐building strategies during their undergraduate education, and to support new graduates with similar programmes when they enter the workforce.

Published: May 2019

AimTo develop and psychometrically test the Basic and Continuing Education Needs of Nurses Instrument.BackgroundNurses need to keep updating their knowledge through engaging in continuing education and professional development activities. Continuing education should be based on needs assessment.MethodsItems generated were devised from a comprehensive literature review guided by Morrel‐Samuels’ guidelines. Psychometric analysis was then performed on data from 3632 registered nurses across 74 Lebanese hospitals. Two‐factor structures were evaluated: the one‐dimensional structure including all items and a six‐dimensional structure proposed by the authors. Reliability, exploratory and confirmatory factor analyses were used. Associations between the total knowledge score and nurses’ characteristics were assessed using linear regression.Results and DiscussionThe total scale had Cronbach's alpha of 0.93 and the six subscales between 0.74 and 0.82. Exploratory factor analysis on the first randomly drawn sample of the data supported the one‐factor structure. Confirmatory factor analysis on the second randomly drawn sample revealed that both structures were acceptable with better fit for the six‐dimensional structure. Linear regression showed significant associations between total score and nurses’ age, income, education and gender. The tool has satisfactory psychometric properties for registered nurses in Lebanon and demonstrated relevance to the Lebanese context of nursing practice.ConclusionWe developed a locally adaptable and psychometrically sound instrument to assess the perceived learning needs of Lebanese nurses. Evidence of the validity and reliability of the instrument was provided.Implications for nursing and health policyAt a practice level, the Instrument allows nurse leaders to assess knowledge gaps and respond accordingly to nurses perceived learning needs at the national level thus improving practice and protecting people's health. At a policy level, this study has implications for developing policies, regulations and guidelines in support of nurses’ continuing education needs and their professional development.

AbstractVertebral fusions are an established economic concern in farmed Atlantic salmon, but have not been studied in detail in farmed Chinook salmon. Two radiographic studies of vertebral fusions were performed in farmed Chinook salmon. Sixteen of 1,301 (1.2%) smolt and 201 of 2,636 (7.6%) harvest fish had fusions. There were no significant differences in the number of fused vertebrae/fusion in smolt compared with harvest fish. Secondly, tagged fish were repeatedly radiographed to determine the progression of the fusions. Nineteen (4.4%), 23 (5.3%) and 39 (9.0%) fish had fusions as smolt, after 129 days in sea water, and at harvest, respectively. There were no significant differences in the average number of vertebra/fusion between the three time points. Of the fusions that were observed in smolt, additional vertebra did not become fused in 81% of the lesions. Within the rare fusions that did progress due to the involvement of adjacent vertebra, an average of 1.6 vertebrae were added per year. Fish with fusions were significantly lighter than non‐affected fish at harvest. Fusions are common in farmed Chinook salmon; however, they are typically stable after development. As fish with fusions were lighter at harvest, reducing fusions may have an economic benefit.
Bacteriophage‐based cocktail modulates selected immunological parameters and post‐challenge survival of rainbow trout (Oncorhynchus mykiss)

Published: May 2019

AbstractRecently, a rapid increase in the resistance of pathogenic bacteria to antibiotics and chemotherapeutics admitted for use in aquaculture has been observed. This happens especially often in intensive breeding. The use of drugs in closed circuits is problematic because it can damage biological filters. Therefore, in recent years, there has been a growing interest in natural methods of combating pathogens. These include bacteriophages. The aim of the study was to determine the safety of the new BAFADOR® bacteriophage‐based preparation, its effect on selected immunological parameters and the effectiveness of prophylactic and therapeutic use after experimental infections with pathogenic bacteria Aeromonas hydrophila and Pseudomonas fluorescens. The use of BAFADOR® increased the activity of lysozyme, total protein level and immunoglobulin level. The level of ceruloplasmin in the rainbow trout serum remained unchanged regardless of the route of administration of the preparation. Potential killing activity and metabolic activity of spleen phagocytes and proliferation of pronephros lymphocytes were higher compared to the control group. Both therapeutic and prophylactic application of the preparation after mixed experimental infection of A. hydrophila and P. fluorescens limited the mortality of rainbow trout.

AbstractIn this study, adulteration in tomato paste was investigated using a gas sensors array. For this purpose, olfactory machine system was evaluated based on five gas sensors to investigate pumpkin, potato, and starch adulteration (0, 5, 10, 15, and 20%). Principal component analysis (PCA), linear discriminant analysis (LDA), support vector machine (SVM), and partial least square (PLS) methods were used for classification and analysis of sensors response. The use of PCA method in the classification of pumpkin, potato, and starch adulteration has explained 99% of the variance between the data. Also, TGS2610, MQ3, TGS2620, and TGS2600 sensors are widely used for classification. LDA method precision for pumpkin, potato, and starch adulteration classification was 79.07, 83.87, and 92.22%, respectively. In SVM method, C‐SVM function as polynomial function and Nu‐SVM as radial base function were used for pumpkin classification with 98.84 and 88.14% precision, respectively. In the classification of potato adulteration, the polynomial function had 90.32 and 83.87% precision in C‐SVM and 96.77 and 86.02% precision in Nu‐SVM. Finally, the two TGS2610 and MQ3 sensors had the best results for classification by PLS. Among the methods of classification, PCA method for categorizing pumpkin adulteration and PLS method in the classification of potato and starch adulteration had the best results.Practical applicationsIn this study, an electronic nose system was examined based on five metal oxide semiconductor sensors to recognize pumpkin, potato, and starch adulteration in tomato paste in combination with pattern recognition methods including PCA, LDA, SVM, and PLS. According to results, it is recommended to use TGS2610 and MQ‐3 sensors combined with PCA and SVM method in the design and development of the electronic nose system. Also, potential of the electronic nose system uses for food adulteration monitoring.

Authors: Mshanga N. , Martin H. , Petrucka P. 
Published: May 2019

AbstractBackgroundMicronutrients comprised of vitamin and mineral nutrients that are needed during pregnancy for foetal growth, development and maturation, as well as for reducing/preventing maternal complications. However, micronutrient‐rich foods (vegetables and fruits) are lacking in the Ngorongoro Conservation Area as a result of restrictions on cultivation in conservation areas and the unavailability of vegetables and fruits in local markets. The present study introduced a food basket intervention and assessed the effectiveness of the food baskets with respect to addressing anaemia, vitamin A and iron deficiencies among pregnant Maasai women within the Ngorongoro Conservation Area.MethodsThe quasi‐experimental study included Misigiyo ward as a control group (provided education only) and Olbalbal ward as an intervention group (provided food baskets and education). The study assessed haemoglobin, serum ferritin and retinol at baseline and during follow‐up. Haemoglobin, serum ferritin and retinol were quantitatively (duplicate) measured with HemoCue™ (HemoCue AB, Ängelholm, Sweden), Maglumi 800 (Snibe Diagnostic, Shenzhen, China) and vitamin A enzyme‐linked immunosorbent assay, respectively. Dependent and independent t‐tests were used to compare the micronutrient blood levels between and within the groups.ResultsThe present study found a statistically significant increase in serum retinol (P < 0.001) in the intervention group compared to the control group; moreover, baseline serum retinol was positively associated with the follow‐up serum retinol, whereas baseline haemoglobin and serum ferritin were negatively associated.ConclusionsThe food basket intervention holds promise with repect to reducing micronutrient deficiency, especially in communities where micronutrient‐rich foods are scarce.
INSTITUTIONAL DETERMINANTS OF VENTURE CAPITAL ACTIVITY: AN EMPIRICALLY DRIVEN LITERATURE REVIEW AND A RESEARCH AGENDA
Authors: Grilli Luca , Latifi Gresa , Mrkajic Boris 
Published: May 2019

AbstractVenture Capital (VC) was born and has flourished in the United States, yet it has only modestly developed in other geographical areas. A vast body of research has been carried out to investigate the factors which are conducive to VC activity, and that may better explain the differences in the degree of development and performance of VC industry across different geographical contexts. However, there has only been a limited effort in the literature to systematize what we know (and what we do not know) about the institutional factors that spur VC activity. This paper tries to close that gap, through a systematic survey of the existing literature on the institutional and related determinants of VC activity. Grounding on the seminal work of North (1990), we consider formal (e.g. laws and formal rules) and informal (e.g. cultural norms and tacit codes of behaviour) institutions which are found in the extant empirical economics and management literature to affect the development of the VC industry. Building on this careful review, our paper aims to propose interesting avenues for future research in this domain.

AbstractBackgroundTo assess the risk of incident cardiovascular disease in patients with primary Sjögren's syndrome, overall and stratified by Ro/SSA and La/SSB autoantibody status.MethodsA cohort of patients with primary Sjögren's syndrome in Sweden (n = 960) and matched controls from the general population (n = 9035) were included, and data extracted from the National Patient Register to identify events of myocardial infarction, cerebral infarction and venous thromboembolism. Hazard ratios were estimated using cox proportional hazard regressions.ResultsDuring a median follow‐up of 9.5 years, the overall hazard ratio (HR) was 1.6 (95% CI 1.2–2.1) for myocardial infarction, 1.2 (95% CI 0.9–1.7) for cerebral infarction and 2.1 (95% CI 1.6–2.9) for venous thromboembolism. Patients positive for both Ro/SSA and La/SSB autoantibodies had a substantially higher risk of cerebral infarction (HR 1.7, 95% CI 1.0–2.9) and venous thromboembolism (HR 3.1, 95% CI 1.9–4.8) than the general population. These risks were not significantly increased in Ro/SSA‐ and La/SSB‐negative patients. Among autoantibody‐positive patients, the highest HR of cerebral infarction was seen after ≥10 years disease duration (HR 2.8, 95% CI 1.4–5.4), while the HR for venous thromboembolism was highest 0–5 years after disease diagnosis (HR 4.7, 95% CI 2.3–9.3) and remained high throughout disease duration.ConclusionsPrimary Sjögren's syndrome is associated with a markedly increased risk of cardiovascular disease and the presence of Ro/SSA and La/SSB autoantibodies identify the subgroup of patients carrying the highest risk. These findings suggest that monitoring and prevention of cardiovascular disease in this patient group should be considered.

Published: May 2019

AbstractObjectivesThis meta‐analysis quantified associations between goal disengagement and goal reengagement capacities with individuals' quality of life (i.e., well‐being and health).MethodsEffect sizes (Fisher's Z′; N = 421) from 31 samples were coded on several characteristics (e.g., goal adjustment capacity, quality of life type/subtype, age, and depression risk status) and analyzed using meta‐analytic random effects models.ResultsGoal disengagement (r = 0.08, p < 0.01) and goal reengagement (r = 0.19, p < 0.01) were associated with greater quality of life. While goal disengagement more strongly predicted negative (r = −0.12, p < 0.01) versus positive (r = 0.02, p = 0.37) indicators of well‐being, goal reengagement was similarly associated with both (positive: r = 0.24, p < 0.01; negative: r = −0.17, p < 0.01). Finally, the association between goal disengagement and lower depressive symptoms (r = −0.11, p < 0.01) was reversed in samples at‐risk for depression (r = 0.08, p = 0.01), and goal disengagement more strongly predicted quality of life in older samples (B = 0.003, p < 0.01).ConclusionsThese findings support theory on the self‐regulatory functions of individuals' capacities to adjust to unattainable goals, document their distinct benefits, and identify key moderating factors.

Published: May 2019

AimTo determine health practitioners' experience of using the culturally adapted Ages and Stages Questionnaire ‐ Talking about Raising Aboriginal Kids (ASQ‐TRAK) and the Ages and Stages Questionnaire‐3 (ASQ‐3) with Australian Aboriginal families and their perception about parents' acceptability and understanding of the instruments.MethodsWe surveyed a convenience sample of practitioners who had used both the ASQ‐TRAK and the ASQ‐3 developmental screening tools with Aboriginal children in the Northern Territory and South Australia. We compared their experience and perception about parents' acceptability and understanding of both instruments.ResultsAll 38 respondents used the ASQ‐3 and 35 the ASQ‐TRAK; 100% rated the ASQ‐TRAK as more acceptable and easier to understand for parents compared with 68% (P < 0.001) and 52.6% (P < 0.001), respectively, for the ASQ‐3. A greater proportion of respondents were satisfied using the ASQ‐TRAK (100%) than the ASQ‐3 (65.7%) (P = 0.003). A higher proportion indicated that the ASQ‐TRAK was respectful (85.3% compared with ASQ‐3 27.8%, P < 0.001), culturally relevant (70.6% compared to 16.2%, P < 0.001) and engaging (76.5% compared to 16.2%, P < 0.001).Qualitative exploration of respondents' comments supported the quantitative findings. The ASQ‐TRAK was considered more culturally appropriate, engaging and useful.ConclusionsOur findings demonstrate that the culturally adapted ASQ‐TRAK is preferred to the ASQ‐3 by health practitioners in the Australian Aboriginal context. Failing to address cultural and linguistic factors and applying measurement tools developed for one population to another, is problematic in any setting. While further research is required to explore parents' experience directly, these data provide support for the ASQ‐TRAK to be used in this context.

AbstractBackgroundThe Italian Liver Cancer (ITA.LI.CA) prognostic system for patients with hepatocellular carcinoma (HCC) has recently been proposed and validated. We sought to explore the relationship among the ITA.LI.CA prognostic variables (ie tumour stage, functional score based on performance status and Child‐Pugh score, and alpha‐fetoprotein), treatment selection and survival outcome in HCC patients.Patients and MethodsWe analysed 4,867 consecutive HCC patients undergoing six main treatment strategies (liver transplantation, LT; liver resection, LR; ablation, ABL; intra‐arterial therapy, IAT; Sorafenib, SOR; and best supportive care, BSC) and enrolled during 2002‐2015 in a multicenter Italian database. In order to control pretreatment imbalances in observed variables, a machine learning methodology was used and inverse probability of treatment weights (IPTW) was calculated. An IPTW‐adjusted multivariate survival model that included ITA.LI.CA prognostic variables, treatment period and treatment strategy was then developed. The survival benefit of HCC treatments was described as a hazard ratio (95% confidence interval), using BSC as a reference value and as predicted median survival.ResultsAfter the IPTW, the six treatment groups became well balanced for most baseline characteristics. In the IPTW‐adjusted multivariate survival model, treatment strategy was found to be the strongest survival predictor, irrespective of ITA.LI.CA prognostic variables and treatment period. The survival benefit of different therapies over BSC was: LT = 0.19 (0.18‐0.20); RES = 0.40 (0.37‐0.42); ABL 0.42 (0.40‐0.44); IAT = 0.58 (0.55‐0.61); SOR = 0.92 (0.87‐0.97). This multivariate model was then used to predict median survival for each therapy within each ITA.LI.CA stage.ConclusionThe concept of therapeutic hierarchy was established within each ITA.LI.CA stage.
Factors predicting identity as educators and openness to improve: an exploratory study

Published: May 2019

ContextResearchers suggest that teachers’ work environment affects their sense of connectedness and appreciation, which affects their educator identity. However, sessional (also known as adjunct, clinical, contingent and non‐tenured) faculty members may struggle with their educator identity. The purpose of this exploratory study was to examine the extent to which perceived connectedness and received appreciation predicted identity as a medical (health care science) educator and openness to improve in tenure‐track and sessional faculty members.MethodsWe utilised an ‘identification with teaching’ scale to measure medical educator identity. We developed scales to measure perceived connectedness to university department, openness to improve teaching, and appreciation as a motivation to try a new teaching method. We then hypothesised a path model between these constructs. We surveyed faculty members at a health sciences school and performed confirmatory factor analyses and structural equation modelling using data from a sample of 73 tenure‐track and 146 sessional faculty members to explore support for the hypothesised model.ResultsConnectedness and appreciation predicted identity as a medical educator and openness to improve in different ways for sessional and tenure‐track faculty members. For tenure‐track faculty members, appreciation predicted medical educator identity and openness to improve, whereas a sense of connectedness trended towards predicting an openness to improve. For sessional faculty members, connectedness to their department predicted their identity as a medical educator, which acted as a mediator to predict an openness to improve.DiscussionOur data supported the hypothesised model, but the sessional and tenure‐track faculty models differed in strength and focus. We explore reasons for these differences based on the working environment of each teacher type. We suggest that the two models partially explain the transformation from ‘a clinician who teaches’ to a medical educator. Finally, we make suggestions for how identity as a medical educator and openness to improve may be encouraged in both types of teachers.
