Registered Nurses (RNs)’ knowledge sharing and decision‐making: the mediating role of organizational trust
Authors: Yoo K.H. , Zhang Y.A. , Yun E.K. 
Published: February 2019

AimThis study study aimed to investigate the effects of explicit and tacit knowledge sharing on clinical decision‐making abilities and the mediating role of trust among registered nurses at Korean hospitals.BackgroundDecision‐making abilities comprise a key area of nursing practice and link nurses’ perceptions with behaviours.IntroductionTacit knowledge is embedded within an individual and cannot be expressed or transmitted to other people in a specific form. Over time, new nurses gradually gain experience and tacit knowledge and become experts. Trust, an organizational characteristic, may serve as a potential mediator in the association between knowledge sharing and decision‐making abilities among nurses. However, few studies have investigated the mediatory role of trust in this association.MethodThe data were collected from 210 nurses selected via random sampling. The research instrument in the model included Knowledge‐Sharing Behavior, Trust, and Clinical Decision‐Making in Nursing Scale. Structural equation modelling was used to analyse the collected data.FindingsThe study findings showed that explicit knowledge sharing directly affects decision‐making abilities, whereas tacit knowledge sharing is only associated with decision‐making abilities when trust plays a mediating role.DiscussionA higher level of organizational trust can improve clinical decision‐making abilities via tacit knowledge sharing.ConclusionThis study demonstrated that unlike explicit knowledge, which is shared more easily, tacit knowledge sharing does not directly lead to clinical decision‐making abilities. A higher level of organizational trust leads to a stronger beneficial effect of tacit knowledge sharing on clinical decision‐making abilities.Implications for nursing and health policyThese findings concerning the mediatory role of trust on the association between knowledge sharing and clinical decision‐making abilities provide new knowledge that will allow nurses, managers, and researchers to support the clinical decision‐making abilities of nurses.

AbstractAimsTo conduct a comparative analysis of four cohorts of newly licensed Registered Nurses and their work schedule, daily shift length, weekly work hours, second job, and weekly overtime hours. Nurses also reported their preferences regarding work schedule and daily shift length.DesignWe used a retrospective, comparative design analysing four cross‐sectional surveys from new nurses first licensed between 2004–2015.MethodsUsing state licensure lists, nurses who were first licensed between 1 August 2004 and 31 July 2005 were randomly sampled using a nested design in 23 geographical areas in 13 states and Washington, DC. The same sampling strategy was conducted for subsequent cohorts in January 2009, 2012, and 2016. We sent a mailed survey measuring demographics, education, work attributes, and attitudes to participants with a $5 incentive, following methods by Dillman.ResultsThere were no statistically significant differences in average weekly work hours (39.4 hrs) or holding more than one job for pay (11.6–14.6% across all cohorts). There were statistically significant differences in overtime across cohorts and shift length by unit type. The preferred shift length was 12 hrs and day shift was the preferred work schedule.ConclusionNew nurses are predominantly scheduled for 12‐hrs shifts and nearly half work weekly overtime, trends that have remained relatively stable over the past 10 years. Nurse managers, policy‐makers, and researchers should pay attention to new nurses’ schedule and shift preferences and guard against mandatory overtime hours.

AbstractIntroductionWe evaluated the association between a novel electrocardiographic (ECG) marker of late, rightward electrocardiographic forces (termed the lead one ratio [LOR]), and left ventricular ejection fraction (LVEF), myocardial scar, and clinical outcomes in patients with left bundle branch block (LBBB).Methods and ResultsLOR was calculated in patients with LBBB from a derivation cohort (n = 240) and receiver operator characteristic curves identified optimal threshold values for predicting myocardial scar and LVEF less than 35%. An independent validation cohort of patients with LBBB (n = 196) was used to test the association of LOR with the myocardial scar, LVEF, and the likelihood of death, heart transplant or left ventricular assist device (LVAD) implantation. The optimal thresholds in the derivation cohort were LOR less than 13.7 for identification of scar (sensitivity 55%, specificity 80%), and LOR less than 12.1 for LVEF less than 35% (sensitivity 49%, specificity 80%). In the validation cohort, LOR less than 13.7 was not associated with scar size or presence (P > 0.05 for both). LOR less than 12.1 was associated with lower LVEF (30 [20‐40] versus 40 [25‐55]%;
P = 0.002) and predicted LVEF less than 35% in univariable (odds ratio [OR], 2.2 [1.2‐4.1];
P = 0.01) and multivariable analysis (OR, 2.2 [1.2‐4.3];
P = 0.02). LOR less than 12.1 was associated with scar presence when patients with nonischemic cardiomyopathy were excluded (OR = 7.2 [1.5‐33.2];
P = 0.002). LOR less than 12.1 had an adjusted hazard ratio of 1.53 ([1.05‐2.21];
P = 0.03) for death, transplant or LVAD implantation.ConclusionsIn conclusion, ECG LOR less than 12.1 predicts reduced‐LV systolic function and poorer prognosis in patients with LBBB.

AbstractBackgroundChronic itch (CI) is a frequent symptom in hemodialysis (HD) patients. Previous studies demonstrated great impairments of general well‐being and health‐related quality of life (HRQOL) as well as a higher mortality in those suffering from CI.ObjectiveThe German Epidemiological Hemodialysis Itch Study (GEHIS) is a representative cohort of HD patients in Germany. All patients were followed up 4 years later. The current analyses present data on the course of CI in HD patients, its associated factors including comorbidities, laboratory values and HRQOL.MethodsWe assessed sociodemographic data, routine laboratory values, comorbidities, HRQOL (SF‐12), depression and anxiety (HADS), sleep (duration and quality) and in those suffering from CI characteristics, intensity of CI and itch‐related quality of life (ItchyQoL). Those with CI were offered a dermatological examination and CI was classified according to the IFSI classification. Patients were asked if they had consulted a physician about CI.ResultsOf the patients who had suffered from CI in 2013 (n = 234), 90.5% (212) patients could be followed up. About 36.3% (n = 85) had died, 9.8% (n = 23) had received a kidney transplant in the meantime. A total of 52 HD patients still suffered from CI, in 52 CI had stopped. Those patients still suffering from CI (n = 52) reported a higher mean itch intensity, lower ItchyQoL, higher levels of anxiety and a lower mean sleeping time in 2013. On the other hand, those who did not suffer from CI anymore showed a significant increase of HRQOL compared to 2013. There was no significant difference in dialysis characteristics and laboratory values except for albumin. Only a minority of patients in HD had consulted a dermatologist because of CI (29.9%).ConclusionOur data demonstrate that CI is a persisting symptom in 50% of the HD patients and when it disappears HRQOL recovers. We confirm that CI is a disregarded symptom in HD patients.

AbstractIn response to concerns that novel infectious agents were introduced through the movement of eggs as Atlantic salmon aquaculture developed in British Columbia (BC), Canada, we estimated the prevalence of infectious agents in archived return‐migrating Sockeye salmon, from before and during aquaculture expansion in BC (1985–94). Of 45 infectious agents assessed through molecular assays in 652 samples, 23 (7 bacterial, 2 viral and 14 parasitic) were detected in liver tissue from six regions in BC. Prevalence ranged from 0.005 to 0.83 and varied significantly by region and year. Agent diversity ranged from 0 to 12 per fish (median 4), with the lowest diversity observed in fish from the Trans‐Boundary and Central Coast regions. Agents known to be endemic in Sockeye salmon in BC, including Flavobacterium psychrophilum, Infectious haematopoietic necrosis virus, Ceratonova shasta and Parvicapsula minibicornis, were commonly observed. Others, such as Kudoa thyrsites and Piscirikettsia salmonis, were also detected. Surprisingly, infectious agents described only recently in BC salmon, Ca. Branchiomonas cysticola, Parvicapsula pseudobranchicola and Paranucleospora theridion, were also detected, indicating their potential presence prior to the expansion of the aquaculture industry. In general, our data suggest that agent distributions may not have substantially changed because of the salmon aquaculture industry.
The effect of spray drying conditions on physicochemical properties of encapsulated propolis powder
Authors: Baysan Ulaş , Elmas Feyza , Koç Mehmet 
Published: February 2019

AbstractHerein we investigated the effects of homogenization rate, inlet, and outlet air temperatures on physical (moisture content, water activity, glass transition temperature, particle and bulk density, wettability, solubility, and color) and chemical (total and surface phenolic content, antioxidant activity and encapsulation efficiency) properties of spray dried encapsulated propolis. The moisture content of encapsulated propolis powder was ranged from 4.26 to 6.17% while, the water activity values of these were changed between 0.197 and 0.269. The moisture content and water activity of products was an upward tendency with increasing inlet air temperature and decreasing outlet air temperature. An increase in inlet air temperature and decrease in outlet air temperature led to an increase in the glass transition temperature which changed in range of 44.50 to 51.45°C. While the wettability time of encapsulated propolis powder was longer than 100 s, their solubility ranged from 82 to 95%. Propolis powder produced at high inlet and outlet air temperatures and low homogenization rate had higher antioxidant activity, total, and surface phenolic content. Encapsulation efficiency calculated based on total/surface phenolic content varied widely between 29.79 and 99.73%. Encapsulation efficiency results clearly demonstrated that the conditions of process variables were effective on the encapsulation process.Practical ApplicationsPropolis is one of the valuable bee products due to its high phenolic content and antioxidant activity. In the current market, propolis is mostly presented as a food supplement in the form of liquid extract. Although the importance of propolis has been recognized by the food industry and consumers, the usage of propolis has been limited due to its bitter and unpleasant taste. Another limitation of propolis usage in food products is environmental factors and food process conditions due to easily loss of its antioxidant activity and phenolic compounds. Encapsulation technology could provide overcome these challenges and improve the usability and durability of propolis in food products as an ingredient. However, the success of an encapsulation process considerably depends on process conditions. Therefore the effects of the encapsulation process conditions of spray drying method on physicochemical properties of encapsulated propolis powder were investigated in this study.
Working conditions in hydrogen production: A social life cycle assessment
Authors: Werker Jasmin , Wulf Christina , Zapp Petra 
Published: February 2019

AbstractSocial impacts of novel technology can, parallel to environmental and economic consequences, influence its sustainability. By analyzing the case of hydrogen production by advanced alkaline water electrolysis (AEL) from a life cycle perspective, this paper illustrates the social implications of the manufacturing of the electrolyzer and hydrogen production when installed in Germany, Austria, and Spain. This paper complements previous environmental and economic assessments, which selected this set of countries based on their different structures in electricity production. The paper uses a mixed method design to analyze the social impact for the workers along the process chain. Appropriate indicators related to working conditions are selected on the basis of the UN Agenda 2030 Sustainable Development Goals. The focus on workers is chosen as a first example to test the relatively new Product Social Impact Life Cycle Assessment (PSILCA) database version 2.0. The results of the quantitative assessment are then complemented and compared through an investigation of the underlying raw data and a qualitative literature analysis. Overall, advanced AEL is found to have least social impact along the German process chain, followed by the Spanish and the Austrian. All three process chains show impacts on global upstream processes. In order to reduce social impact and ultimately contribute to Sustainable Development, policymakers and industry need to work together to further improve certain aspects of working conditions in different locations, particularly within global upstream processes.

SummaryRegenerative medicine opens new opportunities in the repair of cicatricial lesions of the vocal folds. Here, we present a thorough morphological study, with the focus on the collagen structures in the mucosa of the vocal folds, dedicated to the effects of stem cells on the vocal folds repair after cicatricial lesions. We used a conventional experimental model of a mature scar of the rabbit vocal folds, which was surgically excised with a simultaneous implantation of autologous bone marrow‐derived mesenchymal stem cells (MSC) into the defect. The restoration of the vocal folds was studied 3 months postimplantation of stem cells and 6 months after the first surgery. The collagen structure assessment included histology, immunohistochemistry and atomic force microscopy (AFM) studies. According to the data of optical microscopy and AFM, as well as to immunohistochemical analysis, MSC implantation into the vocal fold defect leads not only to the general reduction of scarring, normal ratio of collagens type I and type III, but also to a more complete restoration of architecture and ultrastructure of collagen fibres in the mucosa, as compared to the control. The collagen structures in the scar tissue in the vocal folds with implanted MSC are more similar to those in the normal mucosa of the vocal folds than to those of the untreated scars. AFM has proven to be an instrumental technique in the assessment of the ultrastructure restoration in such studies.Lay DescriptionRegenerative medicine opens new opportunities in the repair of the vocal fold scars. Because collagen is a main component in the vocal fold mucosa responsible for the scar formation and repair, we focus on the collagen structures in the mucosa of the vocal folds, using a thorough morphological study based on histology and atomic force microscopy (AFM). Atomic force microscopy is a scanning microscopic technique which allows revealing the internal structure of a tissue with a resolution up to nanometres. We used a conventional experimental model of a mature scar of the rabbit vocal folds, surgically excised and treated with a mesenchymal stem cells transplant. Our morphological study, primarily AFM, explicitly shows that the collagen structures in the scarred vocal folds almost completely restore after the stem cell treatment. Thus, the modern microscopic methods, and especially AFM are instrumental tools for monitoring the repair of the vocal folds scars.

Published: February 2019

AbstractHerpes zoster (shingles) is the reactivation of dormant varicella zoster virus in individuals who previously experienced varicella infection or vaccination. Herpes zoster can occur in pregnancy, although it is rare. This case report describes the clinical presentation and diagnosis of herpes zoster and reviews current recommendations for treatment. Preventative measures and the role of immunization are discussed in addition to clinical implications for intrapartum, postpartum, and newborn care to guide practitioners in caring for women experiencing or exposed to herpes zoster in pregnancy.

AbstractPelvic floor disorders negatively impact millions of women worldwide. Although there is a strong epidemiological association with childbirth, the mechanisms leading to the dysfunction of the integral constituents of the female pelvic floor, including pelvic floor skeletal muscles, are not well understood. This is in part due to the constraints associated with directly probing these muscles, which are located deep in the pelvis. Thus, experimental models and non‐invasive techniques are essential for advancing knowledge of various phenotypes of pelvic floor muscle injury and pathogenesis of muscle dysfunction, as well as developing minimally invasive approaches for the delivery of novel therapeutics. The most widely used animal model for pelvic floor disorders is the rat. However, the radiological anatomy of rat pelvic floor muscles has not been described. To remedy this gap, the current study provides the first detailed description of the female rat pelvic floor muscles’ radiological appearance on MR and ultrasound images, validated by correlation with gross anatomy and histology. We also demonstrate that ultrasound guidance can be used to target rat pelvic floor muscles for possible interventional therapies.

AbstractThe aim of this study was to determine the main stages of submandibular salivary gland development during the embryonic period in humans. In addition, we studied submandibular salivary gland development in rats on embryonic days 14–16 and expression in the submandibular salivary gland region with the monoclonal antibody HNK‐1. Serial sections from 25 human embryos with a greatest length ranging from 10 to 31 mm (Carnegie stages 16–23; weeks 5.5–8 of development) and Wistar rats of embryonic days (E) 14–16 were analysed with light microscopy. Five stages of submandibular salivary gland development were identified. The prospective stage (1), between weeks 5.5 and early week 6, is characterized by a thickening of the epithelium of the medial paralingual groove in the floor of the mouth corresponding to the primordium of the submandibular salivary gland parenchyma. At this stage, the primordium of the parasympathetic ganglion lies below the lingual nerve. The primordium of the submandibular salivary gland parenchyma is observed in rats on E14 in the medial paralingual groove with mesenchymal cells, underlying the lingual nerve. These cells are HNK‐1‐positive, corresponding to the primordium of the parasympathetic ganglion. The bud stage (2), at the end of week 6 in humans and on E15 in rats, is characterized by the proliferation and invagination of the epithelial condensation, surrounded by an important condensation of the mesenchyme. The pseudoglandular stage (3) at week 6.5 is characterized by the beginning of the formation of lobes in the condensed mesenchyme. The canalicular stage (4), between week 7 and 7.5, is characterized by the appearance of a lumen in the proximal part of the submandibular duct. The innervation stage (5) occurs during week 8, with the innervation of the submandibular and interlobular ducts. Nervous branches arriving from the parasympathetic ganglion innervate the glandular parenchyma. Numerous blood vessels are observed nearby. Our results suggest that submandibular salivary gland development requires interactions among epithelium, mesenchyme, parasympathetic ganglion and blood vessels.
