Understanding the impostor phenomenon in graduate nursing students.

Intuitively, nurse educators know that graduate students in both master's and doctoral programs question their ability to succeed. The impostor phenomenon (IP) is an internalized sense of inadequacy and fear of being seen as a fraud in the presence of external indicators of authentic achievement, and experienced by high achieving, successful individuals. Fifty-three percent (49/93) of graduate students completed the CIPS survey, and 11 master's (regular streams & nurse practitioner) and two doctoral students participated in focus group interviews. The quantitative results showed that 88 % of participants experienced moderate to intense impostor phenomenon. Two themes emerged in the qualitative analysis: (i) experiencing the imposter phenomenon and (ii) managing feeling like an impostor. Descriptions of IP were similar across the three groups of participants. This research provides a foundational understanding of how IP is experienced by graduate nursing students.

Stress, depression, and anxiety among undergraduate nursing students in the time of a pandemic.

INTRODUCTION: Emerging literature reports on the challenges faced by nursing students internationally during the pandemic as they continue their education. The aim of this mixed methods study was to examine stress, depression, and anxiety among undergraduate nursing students at a Canadian university during the pandemic. THEORETICAL FRAMEWORKS: Stress and coping and trauma theories informed this study. METHODS: Mixed methods included an online questionnaire composed of the Depression Anxiety Stress scales (DASS), sociodemographic data, and quality of life items with open-ended questions. RESULTS: Sample included 280 participants. Mean scores for depression and stress were in the mild level, for anxiety in the moderate level; 24 , 37 and 23 % of the sample had scores of severe or extremely severe for depression, anxiety, and stress respectively. Written comments reflected the impact on participants' relationships, motivation, struggles with remote learning, perceived heavy workloads, and impact on health and self-care, while some described positive experiences, including improved study habits. DISCUSSION: Uncertainty, isolation, sudden and ongoing changes with program delivery and a variety of psychosocial losses, helped to explain the distress many shared. The disconnect between reported levels of use of mental health services and the higher levels of mental distress raises the question of access to and use of these services. IMPLICATIONS FOR AN INTERNATIONAL AUDIENCE: The importance of developing and maintaining effective coping, including a support system, and committing to healthy self-care during challenging times was reinforced. CONCLUSIONS: This difficult time for nursing students emphasized the need to ensure attention to student well-being and mental health during their foundational educational experiences.

Citation analysis of Canadian psycho-oncology and supportive care researchers.

PURPOSE: The purpose of this study was to conduct a historical review of psycho-oncology and supportive care research in Canada using citation analysis and to review the clinical impact of the research conducted by the most highly cited researchers. METHODS: The lifetime journal publication records of 109 psycho-oncology and supportive care researchers in Canada were subject to citation analysis using the Scopus database, based on citations since 1996 of articles deemed relevant to psychosocial oncology and supportive care, excluding self-citations. Three primary types of analysis were performed for each individual: the number of citations for each journal publication, a summative citation count of all published articles, and the Scopus h-index. RESULTS: The top 20 psycho-oncology/supportive care researchers for each of five citation categories are presented: the number of citations for all publications; the number of citations for first-authored publications; the most highly cited first-authored publications; the Scopus h-index for all publications; and the Scopus h-index for first-authored publications. The three most highly cited Canadian psycho-oncology researchers are Dr. Kerry Courneya (University of Alberta), Dr. Lesley Degner, (University of Manitoba), and Dr. Harvey Chochinov (University of Manitoba). CONCLUSIONS: Citation analysis is useful for examining the research performance of psycho-oncology and supportive care researchers and identifying leaders among them.

Engaging undergraduate nursing students in research: the students' experience of a summer internship program pilot project.

Educators continue to struggle with ways to foster an interest in and a passion for nursing research among undergraduate students. The purpose of this article is to describe the introduction of undergraduate student internships at the Manitoba Centre for Nursing and Health Research, Faculty of Nursing, University of Manitoba, as an innovation in education that allowed students to be employed while engaging them in student learning, scientific inquiry, and scholarship through one-to-one faculty-student research mentorships. In this article, the key components of the summer internship program are described, along with five nursing students' experiences of their participation in the program.

Research citation analysis of nursing academics in Canada: identifying success indicators.

AIM: This article is a report of a citation analysis of research publications by Canadian nursing academics. BACKGROUND: Citation analysis can yield objective criteria for assessing the value of published research and is becoming increasingly popular as an academic evaluation tool in universities around the world. Citation analysis is useful for examining the research performance of academic researchers and identifying leaders among them. METHODS: The journal publication records of 737 nursing academics at 33 Canadian universities and schools of nursing were subject to citation analysis using the Scopus database. Three primary types of analysis were performed for each individual: number of citations for each journal publication, summative citation count of all published papers and the Scopus h-index. Preliminary citation analysis was conducted from June to July 2009, with the final analysis performed on 2 October 2009 following e-mail verification of publication lists. RESULTS: The top 20 nursing academics for each of five citation categories are presented: the number of career citations for all publications, number of career citations for first-authored publications, most highly cited first-authored publications, the Scopus h-index for all publications and the Scopus h-index for first-authored publications. CONCLUSION: Citation analysis metrics are useful for evaluating the research performance of academic researchers in nursing. Institutions are encouraged to protect the research time of successful and promising nursing academics, and to dedicate funds to enhance the research programmes of underperforming academic nursing groups.

A cDNA for a putative type III deiodinase in the trout (Oncorhynchus mykiss): influence of holding conditions and thyroid hormone treatment on its hepatic expression.

A putative rainbow trout type III deiodinase (D3) cDNA was amplified by PCR, using primers to evolutionarily conserved sequences. The RACE-derived complete cDNA was then identified by sequence comparison to that in tilapia and other vertebrates. The cDNA coded for a predicted 31,500 kDa protein of 278 amino acids, with a hydrophobic trans-membrane segment and with 80% similarity to tilapia D3 and 39% similarity to rainbow trout type II deiodinase (D2). It also showed a selenocysteine codon at position 141 and a putative SECIS element in the 3' untranslated end. In the liver, a second form of D3 was found that differed only at this 3' untranslated region; the coding region was identical in both forms. The D3 mRNA, measured by RT-PCR using primers located within the common, translated portion of the cDNA, was expressed in the brain and, depending on thyroidal status, in liver and kidney. Holding trout for 7 days in static water as opposed to flowing water caused increased plasma T4 levels, decreased hepatic D2 mRNA levels and T4 outer-ring deiodination (ORD) activity and increased D3 mRNA levels and T3 inner-ring (IRD) activity. Trout held in flowing water and fed T3 for 7 days showed increased plasma T3 levels and hepatic D3 mRNA levels and T3 IRD activity but decreased D2 mRNA levels and T4ORD activity. Trout held in static water and exposed to ambient T4 for 7 days showed increased plasma T4 levels and hepatic T3IRD activity but with no significant change in D2 or D3 mRNA levels. We conclude that hepatic D3 mRNA levels and T3IRD activity are enhanced and D2 mRNA levels and T4ORD activity are suppressed by adverse holding conditions or T3 treatment suggesting that the putative D3 cDNA and D2 cDNA represent respectively the genes determining T3IRD and T4ORD activities. However, there were changes in the ratios of mRNA levels to enzyme activity, raising the potential for post-transcriptional regulation and showing that mRNA levels alone may be unreliable indices of deiodinase activity. Post-transcriptional regulation of D3 enzyme activity may be influenced by the observed alternative 3' and 5' untranslated regions of the D3 mRNA.

Thyroid of lake sturgeon, Acipenser fulvescens. I. Hormone levels in blood and tissues.

The authors measured thyroid hormone (TH) levels in plasma, whole carcass, and tissues of cultured 2-year-old immature lake sturgeon held in fresh water and in serum of adults at spawning time from the Winnipeg River. Circulating thyroxine (T4) and 3,5,3'-triiodothyronine (T3) levels were low (T4 approximately 0.3 ng/ml, T3 approximately 0.2 ng/ml) in all cultured fish and most adults, but a few of the latter had exceptionally high T4 and T3 levels. The percentages of blood TH found in erythrocytes were 19.5% (T4), 6.1% (T3) and 6.9% (reverse T3 = rT3). Equilibrium dialysis showed much higher percentages of plasma free (F) FT4 (1.1%), FT3 (0.4%), and FrT3 (3,3',5'-triiodothyronine = rT3, 3.0%) for sturgeon than for rainbow trout, indicating more limited TH binding to sturgeon plasma sites. However, concentrations of FT4 and FT3 were close to those reported for salmonids. T3 levels exceeded T4 levels in most extrathyroidal tissues of cultured sturgeon but in most cases were less than 0.1 ng/g and 10 to 100 times lower than reported for salmonids; only the whole brain T3 concentration (5.6 ng/g) approached that of salmonids. The digested thyroid contained 21.3 ng T3/g and 2.4 ng T4/g. The authors conclude that lake sturgeon have a low circulating reserve of bound TH but have FT4 and FT3 concentrations close to those of salmonids. The high thyroidal T3:T4 ratio and low tissue T4 levels suggest that, in contrast to teleosts studied to date, the thyroid may be a significant direct source of T3, the primary TH in sturgeon tissues. High serum T4 and T3 levels in some sturgeon at spawning time may suggest a thyroid role in reproduction.

Thyroid of lake sturgeon, Acipenser fulvescens. II. Deiodination properties, distribution, and effects of diet, growth, and a T3 challenge.

The authors studied the properties and tissue distribution of thyroid hormone (TH) deiodination activities measured in vitro at subnanomolar substrate levels for cultured 2-year-old lake sturgeon held at 12 to 15 degrees. We also studied the deiodination responses to an exogenous 3,5,3'-triiodothyronine (T3) challenge and to a diet-induced growth suppression. Thyroxine (T4) outer-ring deiodination (T4ORD), T4 inner-ring deiodination (T4IRD), T3IRD, and 3,3',5'-triiodothyronine (rT3)ORD activities were evident in liver and intestine. Their properties resembled those of teleosts. T3IRD and T4IRD activities predominated in brain. Low or negligible deiodination in any form occurred in gill, skeletal muscle, kidney, notochord, or immature gonad. Only T4ORD activity was evident in the thyroid, suggesting that it secretes some T3. T3ORD and rT3IRD activities were undetectable in any tissues. Hepatic T4ORD activity varied during the photophase and was highest during late morning. A dietary T3 challenge that doubled plasma T3 levels decreased hepatic T4ORD activity without altering any other deiodination pathways in liver, intestine, or brain. A diet change from trout pellets to ocean zooplankton reduced somatic growth and plasma T3 levels and increased hepatic and intestinal T3IRD activities and hepatic rT3ORD activity but did not alter hepatic or intestinal T4ORD activity. The authors conclude that plasma T3 in lake sturgeon can be derived both from the thyroid and from hepatic (and intestinal) T4ORD activity, which varies with sampling time and downregulates in response to a T3 challenge. However, a reduction in plasma T3 accompanying a change in diet and reduced growth was not due to a decrease in T4ORD activity; rather, it was due to an increase in hepatic and intestinal T3IRD activities. These results suggest a difference in emphasis in thyroidal regulation between sturgeon and certain teleosts.
