Incivility experiences of nursing students in South Korea
Authors: Hyun Myung Sun , De Gagne Jennie C , Park Jeonghwa , Kang Hee Sun 
Published: December 2017

Background: Incivility behaviors are negative social behaviors that can create conflict and disrespect among the persons involved. In a learning environment, incivility negatively affects learning by reducing academic motivation, lowering satisfaction with the education program, and interrupting the learning process. In addition, incivility causes those involved to feel negative emotions, such as anger, depression, and anxiety. Research question: What are the incivility experiences of nursing students during their nursing education? In what context do nursing students experience incivility during their education? Research design: This study used an exploratory qualitative methodology. Participants and research context: Participants (n = 34) were nursing students at three universities in South Korea. Data were collected during focus group interviews of 34 participants between 20 March and 26 June 2015 and were examined using a qualitative content analysis. Ethical consideration: The institutional review board approved this study. Findings: The analysis revealed four learning contexts in which participants experienced incivility: (a) in the classroom, (b) outside the classroom, (c) clinical settings, and (d) related to technology use. Five themes were identified: student non-adherence to classroom standards, faculty non-adherence to classroom standards, lack of helping-trusting relationships with peers, lack of dedication to teaching and learning in a clinical setting, and inappropriate use of technology. Conclusion: Nursing students experience incivility in a variety of situations and settings and expect a safer, more positive learning environment. The incivility experienced by nursing students during their education affects their goal of becoming professional nurses.
Conflicts of conscience in the neonatal intensive care unit: Perspectives of Alberta
Authors: Ford Natalie J , Austin Wendy 
Published: December 2017

Background: Limited knowledge of the experiences of conflicts of conscience found in nursing literature. Objectives: To explore the individual experiences of a conflict of conscience for neonatal nurses in Alberta. Research design: Interpretive description was selected to help situate the findings in a meaningful clinical context. Participants and research context: Five interviews with neonatal nurses working in Neonatal Intensive Care Units throughout Alberta. Ethical consideration: Ethics approval from the Health Research Ethics Board at the University of Alberta. Findings: Three common themes emerged from the interviews: the unforgettable conflict with pain and suffering, finding the nurse’s voice, and the unique proximity of nurses. Discussion and conclusion: The nurses described a conflict of conscience when the neonate in their care experienced undermanaged pain and unnecessary suffering. During these experiences, they felt guilty, sad, hopeless, and powerless when they were unable to follow their conscience. Informal ways to follow their conscience were employed before declaration of conscientious objection was considered. This study highlights the vital importance of respecting a conflict of conscience to maintain the moral integrity of neonatal nurses and exposes the complexities of conscientious objection.
Gender dysphoria in Klinefelter’s syndrome: three cases
Authors: Davies Gordon W , Parkinson John 
Published: December 2017

Background: Previous reports have found the incidence of gender dysphoria in Klinefelter’s patients greater than in the general male population. Methods: A cohort of patients with gender dysphoria was reviewed. Results: Of the 220 patients with gender dysphoria, three had Klinefelter’s syndrome. Conclusions: These three reports are further examples of gender dysphoria in Klinefelter’s syndrome. The role of biological factors in gender identity is affirmed. Caution is urged in prescribing testosterone.
Spectrum of care: Current management of childhood autism spectrum disorder (ASD) in New Zealand
Authors: Thabrew Hiran , Eggleston Matthew 
Published: December 2017

Objectives: The purpose of this research was to compare the current status of assessment and intervention for New Zealand children and adolescents who have autism spectrum disorder (ASD) with recommendations outlined in the 2008 New Zealand ASD Guideline. Methods: ASD coordinators and New Zealand District Health Board (DHB) staff working with children and adolescents who have ASD were electronically surveyed. Results: Responses were received from 32 staff in 17 (85%) surveyed DHBs. Positive findings included the presence of ASD coordinators in 85% of DHBs, clear pathways for management in 73.1% of DHBs and good communications between paediatric, psychiatric and educational teams in some DHBs regions. Areas for improvement included wait times to assessment, access to longer-term support and intervention for families, and training for staff in ASD and cultural issues. Conclusions: Since the launch of the NZ ASD Guidelines, significant progress has been made. However, further work is needed to ensure services for children and adolescents with ASD are accessible, well-coordinated and focussed on both assessment and intervention.

Published: December 2017

The availability of direct oral anticoagulants has caused a paradigm shift in thrombosis management. The direct thrombin inhibitor dabigatran seems to obstruct tenase complex by inhibiting thrombin generated in the initial phase and feed back to the amplification phase of cell-based coagulation reactions. However, it is still not fully understood if and how dabigatran impact platelet function. This observational study aimed to assess in vitro platelet function in patients with atrial fibrillation receiving dabigatran. Platelet aggregability was tested with platelet-rich plasma using platelet aggregometry (PACKS-4 aggregometer). Blood samples were stimulated with thrombin receptor agonist peptide (TRAP; 32 μmol/L). Results: A total of 28 patients with nonvalvular atrial fibrillation were enrolled. The mean age was 71.57 (9.75) years (range: 50-87 years), 16 patients were women, and the mean CHA2DS2VASc score was 3.93 (1.41). All patients began treatment with dabigatran as initial anticoagulant treatment. The minimum term use of dabigatran was 18 days. Dabigatran doses were 110 mg (57.14%) or 150 mg (42.86%) twice daily. The TRAP-induced platelet aggregation was significantly lower 2 hours after taking dabigatran compared to baseline value (79.39 [13.38] vs 90.14 [10.5]). Conclusion: The TRAP-induced platelet aggregation was reduced in cardiovascular patients 2 hours after receiving dabigatran. Our findings could have some important clinical implications because platelet aggregation and coagulation cascade are affected at the same time.

Objective We describe an apparently unique case of an extra-uterine leiomyoma in the cervical paraspinal tissue including its evaluation and management. Methods A 14-year-old girl was referred to the neurology clinic for an abnormal head CT following a concussion. MRI revealed a homogenously enhancing left cervical paraspinal mass. The patient underwent complete resection and subsequent genetic testing and counseling were obtained to determine the presence of Li–Fraumeni Syndrome (LFS) or Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) mutations. Result Histopathological examination proved that the tumor was a benign leiomyoma. Genomic testing for Fumarate Hydratase Gene, HLRCC, TP53 mutations or deletions, and LFS sequencing were negative. Further testing showed no immunosuppression. Conclusions To the best of our knowledge, this is the only case of paraspinal leiomyoma to have been reported to date. We emphasize the importance of considering immunosuppression, LFS, or HLRCC as an underlying cause in extra-uterine leiomyata.

Published: December 2017

Objectives The outcome of radioiodine therapy in hyperthyroid cats is suspected to be influenced by multiple factors. The degree of activity of the thyroid gland, represented by uptake of sodium pertechnetate or tracer activities of radioiodine by the thyroid gland on thyroid scintigraphy, has been suggested in the literature as one of those. Thyroid gland pertechnetate uptake can be represented by (semi-)quantitative factors such as the thyroid to salivary gland (T/S) ratio, the thyroid to background (T/B) ratio and the percentage technetium uptake by the thyroid glands (%TcU). The aim of this study was to investigate a possible relationship between these thyroid scan parameters and radioiodine therapy outcome. Methods Sodium pertechnetate thyroid scans of 75 hyperthyroid cats were retrospectively evaluated and statistical analysis was performed with and without correction for injected radioiodine activity. Three different background regions of interest (ROIs) were used to calculate the T/B ratio and %TcU: ‘neck’, ‘circle’ and ‘copy ROI’. Results Higher T/S ratios were found to be significantly related to a persistent hyperthyroid outcome in both analyses. For the T/S ratio, a threshold value of 5.4 was determined, with a sensitivity of 73% and a specificity of 59%. An increased risk for persistent hyperthyroidism compared with a final euthyroid outcome with an increased T/Bcircle ratio was only found to be significant without correction for the activity of radioiodine administered. For the %TcU no statistical significance was reached. Regarding a low total thyroxine outcome, no significant relationships with any of the investigated parameters were found. Conclusions and relevance The findings of this study suggest that semi-quantification of thyroid gland uptake is best performed using the T/S ratio. A T/S ratio ⩾5.4 is a possible indicator for an increased risk of persistent hyperthyroidism.

Published: December 2017

Objectives Flow cytometry (FC) is becoming increasingly popular among veterinary oncologists for the diagnosis of lymphoma or leukaemia. It is accurate, fast and minimally invasive. Several studies of FC have been carried out in canine oncology and applied with great results, whereas there is limited knowledge and use of this technique in feline patients. This is mainly owing to the high prevalence of intra-abdominal lymphomas in this species and the difficulty associated with the diagnostic procedures needed to collect the sample. The purpose of the present study is to investigate whether any pre-analytical factor might affect the quality of suspected feline lymphoma samples for FC analysis. Methods Ninety-seven consecutive samples of suspected feline lymphoma were retrospectively selected from the authors’ institution’s FC database. The referring veterinarians were contacted and interviewed about several different variables, including signalment, appearance of the lesion, features of the sampling procedure and the experience of veterinarians performing the sampling. Statistical analyses were performed to assess the possible influence of these variables on the cellularity of the samples and the likelihood of it being finally processed for FC. Results Sample cellularity is a major factor in the likelihood of the sample being processed. Moreover, sample cellularity was significantly influenced by the needle size, with 21 G needles providing the highest cellularity. Notably, the sample cellularity and the likelihood of being processed did not vary between peripheral and intra-abdominal lesions. Approximately half of the cats required pharmacological restraint. Side effects were reported in one case only (transient swelling after peripheral lymph node sampling). Conclusions and relevance FC can be safely applied to cases of suspected feline lymphomas, including intra-abdominal lesions. A 21 G needle should be preferred for sampling. This study provides the basis for the increased use of this minimally invasive, fast and cost-effective technique in feline medicine.
Curative-intent radical en bloc resection using a minimum of a 3 cm margin in feline injection-site sarcomas: a retrospective analysis of 131 cases
Authors: Müller Nina , Kessler Martin 
Published: December 2017

Objectives Owing to its highly infiltrative growth, feline injection-site sarcoma (FISS) carries a significant risk of local tumour recurrence. Parameters of possible prognostic significance (eg, tumour size and location, resection of de novo vs recurrent tumours, and achievement of tumour-free surgical margins) were examined with regard to their influence on recurrence rate (RR), disease-free interval (DFI) and survival time (ST). Methods This was a retrospective analysis of cats with FISSs located on the chest or abdominal wall or the interscapular region treated in a single institution using a standardised radical resection technique with 3 cm lateral margins and full-thickness body wall resection (tumours over chest/abdominal wall) or a minimum of two fascial planes (interscapular tumours). Results Median postoperative DFI and ST of 131 cats with FISSs was 21 and 24 months, respectively. Patients operated on for recurrent tumours were significantly more likely to die from tumour-related reasons compared with patients with de novo tumours ( P <0.001). RR and DFI in the different tumour locations were comparable ( P = 0.544 and P = 0.17, respectively). Local tumour recurrence occurred in 38.1% of the cats. Cats operated on for tumour recurrences had a significantly higher chance of another recurrence (RR 55.5% vs 33.3%; P = 0.005). Completeness of excision was determined by taking tumour bed biopsies. Tumour bed biopsies that did not contain tumour cells were associated with a significantly lower RR compared with those with tumour cells (30.5% vs 76.2%). Conclusions and relevance Depending on prognostic factors such as surgery for primary vs recurrent tumour, tumour-free resection margins and tumour location, the RR in FISS ranges from 33–55%, despite curative intent radical surgery. This study may help in identifying patients at risk for recurrence.

Published: December 2017

Objectives The aim was to retrospectively evaluate the effects of acid-suppressant therapy in a population of cats with chronic kidney disease (CKD). The study objectives were to evaluate the effects of acid-suppressant therapy on clinicopathologic variables and progression of CKD over time. Methods The databases of two institutions were searched over an 11 year time span for cats fitting inclusion criteria for CKD. A total of 89 cats met the criteria for inclusion and were grouped according to either early (ie, stages 1–2) or advanced (ie, stages 3–4) CKD. Variables were statistically analyzed before and after treatment with either: (1) proton pump inhibitors (PPIs; n = 17), (2) histamine-2 receptor antagonists (H2RAs; n = 30), (3) combined acid-suppressant therapy (PPI + H2RA; n = 6) or (4) no acid-suppressant therapy (n = 36). Shapiro–Wilk testing and Q-Q plots were used to assess normality and variance, respectively. A complete randomized design with a mixed-effects repeated measures ANOVA was used to evaluate for differences in stage, treatment and time, as well as the interaction between these effects. Results A significant increase in blood creatinine concentration was found over time independent of severity of CKD and treatment group ( P = 0.0087). A significant increase in blood sodium concentration (change of 3.12 mmol/l) was found independent of stage in cats receiving PPI therapy ( P = 0.0109). A significant decrease in total blood magnesium (change of 0.15 mmol/l) was detected in two cats with early CKD receiving combined acid suppressants ( P = 0.0025). Conclusions and relevance Results of this retrospective study suggest that cats with CKD receiving PPI therapy may develop alterations in blood sodium concentrations but do not experience more rapid progression of CKD.

Published: December 2017

Objectives Radioiodine (131I) dose determination using radiotracer kinetic studies or scoring systems, and fixed relatively high 131I dose (ie, 4 or 5 mCi) administration, are effective and associated with prolonged survival times for hyperthyroid cats. The latter method is less complicated but could expose patients and veterinary personnel to unnecessary levels of radiation. The aim of this study was to retrospectively evaluate the efficacy of a fixed 3.35 mCi 131I dose for the treatment of 96 hyperthyroid cats with no length estimation for any palpated goitre ⩾20 mm, assess outcome and identify factors associated with survival. Methods Serum total thyroxine concentrations at diagnosis and at follow-up times, survival times and cause of death were recorded. Multivariable Cox regression analysis was used to identify factors associated with time to any cause of death from 131I therapy initiation. Results Administration of a median (interquartile range) dose of 3.35 mCi (3.27–3.44 mCi) radioiodine was an effective treatment in 94/96 cats, but two cats remained hyperthyroid. No death related to hyperthyroidism was recorded. Median survival time was 3.0 years; the 1 and 2 year survival rates after 131I therapy were 90% and 78%, respectively. Low body weight (⩽3.1 kg; adjusted hazard ratio [aHR] 5.88; 95% confidence interval [CI] 2.22–16.67; P <0.01) and male gender (aHR 2.63; 95% CI 1.01–7.14; P = 0.04) were independently associated with death, whereas age, prior treatment with antithyroid drugs, reason for treatment and pretreatment azotaemia were not. Conclusions and relevance This study suggests that a fixed 3.35 mCi 131I dose treatment is effective for hyperthyroid cats with goitre(s) with a maximal length estimation <20 mm, that long-term survival can be achieved and that low body weight and male gender are significantly associated with shorter survival times.

Published: December 2017

Objectives The aims of this study were to describe the paravertebral brachial plexus (PBP) blockade in cats, and compare the spread of bupivacaine–methylene blue solution (BMS) using two volumes of injection into the PBP. Methods Six cadavers (4.4 ± 1.8 kg) randomly received 0.15 ml/kg (LOW) or 0.2 ml/kg (HIGH) per injection of BMS into the PBP. The first injection was made ventral to the transverse process of the sixth cervical vertebra (nerves C6 and C7) at the emergence of nerve roots. A second injection was performed at the edge of the cranial border of the scapula and directed ventrally towards the first rib (C8 and T1). Cadavers were dissected and the presence of BMS in contact with the nerves (success rate) and length of staining were evaluated for each nerve (C6/C7/C8/T1). Length of target nerves in contact with BMS was measured and <15 mm was considered fair, ⩾15 mm sufficient and >40 mm excessive. Complications (aspiration of blood, staining of pleural space and/or spinal cord) were recorded. Paired t-test, Mann-Whitney U-test and χ2 test were used for statistical analysis when appropriate ( P <0.05). Results Eleven hemilateral brachial plexuses were injected. Aspiration of blood occurred during one injection. Inadvertent pleural or spinal staining was not observed. Success rates (positive nerve staining) in the LOW and HIGH groups, respectively, were as follows: C6: 83% and 80%; C7: 66% and 100%; C8: 66% and 100%; T1: 50% and 60% ( P >0.05). Median (range) length of nerve staining was 22 mm (15–39 mm) for LOW and 21 mm (13–35 mm) for HIGH ( P >0.05). Excessive nerve staining was not recorded. Conclusions and relevance This study describes the PBP blockade in cats with acceptable nerve staining and minimal complications. Success rate and length of nerve staining were not significantly different between the LOW and HIGH groups.
Open-mouth jaw locking in cats: a literature review and use of CT in three cases
Authors: Nutt Anna E , Anderson Thomas , Gracis Margherita , Doran Ivan , Warren-Smith Chris , Langley-Hobbs Sorrel J 
Published: December 2017

Case series summary This report summarises and reviews the published cases of open-mouth jaw locking in cats and describes three further cases. Case 1 was a 5-year-old, 5.3 kg male neutered domestic shorthair cat. CT identified changes consistent with temporomandibular joint (TMJ) dysplasia with osseous degenerative changes, and the cat subsequently underwent bilateral partial zygomectomy with bilateral partial coronoidectomy. Case 2 was a 10-year-old, 6.0 kg male neutered Exotic Shorthair. Aside from a fracture of the left maxillary canine tooth crown and absence of the left maxillary fourth premolar tooth, no abnormalities were found on CT scan. The cat also underwent bilateral partial zygomectomy with bilateral partial coronoidectomy. The third case was a 1-year-old, 4.0 kg male neutered Persian cat. Changes on CT were consistent with bilateral TMJ dysplasia, and the cat underwent staged bilateral partial zygomectomy with bilateral partial coronoidectomy. There was no recurrence of open-mouth jaw locking in any of the cases on long-term follow-up. Relevance and novel information Open-mouth jaw locking has been reported in cats of a wide range of ages, from 1–10 years. Cats with all skull types (brachycephalic, mesaticephalic and dolichocephalic) may be affected, but brachycephalic breeds seem to be over-represented. A CT scan with the jaw locked in place is recommended for diagnosis and surgical planning purposes; two of the cases reported here document the first cases of TMJ dysplasia in cats to be definitively diagnosed using CT. Trauma and symphyseal or TMJ laxity may also predispose to development of the condition. Partial coronoidectomy and partial zygomatic arch resection performed alone or in combination are generally successful at preventing recurrence. Bilateral partial zygomectomy with bilateral partial coronoidectomy has not previously been reported as a surgical treatment, and is recommended when open-mouth jaw locking occurs bilaterally.
