Assessing the competences associated with a nursing Bachelor thesis by means of rubrics.

BACKGROUND: Writing a Bachelor thesis is the last step in obtaining a university degree. The thesis may be job- or research-orientated, but it must demonstrate certain degree-level competences. Rubrics are a useful way of unifying the assessment criteria. OBJECTIVES: To design a system of rubrics for assessing the competences associated with the Bachelor thesis of a nursing degree, to examine the system's reliability and validity and to analyse results in relation to the final thesis mark. DESIGN: Cross-sectional and psychometric study conducted between 2012 and 2014. SETTINGS: Nursing degree at a Spanish university. PARTICIPANTS: Twelve tutors who designed the system of rubrics. Students (n = 76) who wrote their Bachelor thesis during the 2013-2014 academic year. METHODS: After deciding which aspects would be assessed, who would assess them and when, the tutors developed seven rubrics (drafting process, assessment of the written thesis by the supervisor and by a panel, student self-assessment, peer assessment, tutor evaluation of the peer assessment and panel assessment of the viva). We analysed the reliability (inter-rater and internal consistency) and validity (convergent and discriminant) of the rubrics, and also the relationship between the competences assessed and the final thesis mark. RESULTS: All the rubrics had internal consistency coefficients >0.80. The rubric for oral communication skills (viva) yielded inter-rater reliability of 0.95. Factor analysis indicated a unidimensional structure for all but one of the rubrics, the exception being the rubric for peer assessment, which had a two-factor structure. The main competences associated with a good quality Bachelor thesis were written communication skills and the ability to work independently. CONCLUSION: The assessment system based on seven rubrics is shown to be valid and reliable. Writing a Bachelor thesis requires a range of degree-level competences and it offers nursing students the opportunity to develop their evidence-based practice skills.

[Usefulness of transesophageal echocardiography in the diagnosis of coronary anomalies]. / Utilidad de la ecocardiografía transesofágica en el diagnóstico de anomalías coronarias.

BACKGROUND: Although rare, anomalous coronary arteries are associated with myocardial ischemia and sudden death. Identification is made by angiography but its true course is difficult to determine even with this invasive procedure. OBJECTIVES: The purpose of this study is to determine the role of transesophageal echocardiography (TEE), Doppler and color flow Doppler, in identifying the origin and course of anomalous coronary arteries. MATERIAL AND METHODS: Six patients with angiographically confirmed anomalous coronary arteries were studied by TEE, Doppler and color flow Doppler. RESULTS: The abnormal origin was confirmed in all six patients. In three, the left main originated from the right sinus of Valsalva. In one the right coronary artery from the left sinus of Valsalva. One was a single right coronary artery from the right sinus of Valsalva, and one, had a fistula between the coronary artery and the right ventricle. In four, the TEE was able to demonstrate clearly the course in relation to the great vessels, two were interarterial and one posterior. Color flow Doppler was obtained in four patients. In one patient, there was increase in diastolic flow velocity due to proximal coronary obstruction. One had increase of the systolic flow velocity. CONCLUSIONS: TEE is useful test for diagnosing the origin of anomalous coronary arteries and confirming its course in relation to the great vessels. Doppler flow Doppler is useful in localization the vessel.

[Pericardial effusion simulating a tumor. The value of Doppler color echocardiography for its differentiation]. / Derrame pericárdico que simula un tumor. Valor de la ecocardiografía Doppler a color para su diferenciación.

We describe the case of a patient aged 64 with aortic valve disease and pericardial effusion. Echocardiographic evaluation showed an intrapericardial mass of about 7 cm of diameter with clotted appearance, adhered to the visceral leaf, at the level of the atrio-ventricular function. Because of this finding we performed color codified Doppler echocardiography, observing that this mass acquired a blue hue during diastole and mosaic hue at the end of the systole, realizing that this phenomenon was due to fluid retention. There are many publications about the value of echocardiography for the identification of pericardial masses and some of them show how an effusion can hide a tumor. The interest of this particular case lies in that the effusion simulated a tumor and by means of the color codified Doppler we could demonstrate that it corresponded to the stream of the pericardial fluid. During the surgical procedure the absence of the mass was corroborated.

[Exercise test with cold water intake. Preliminary results]. / Prueba de esfuerzo con ingestión de agua fría. Resultados preliminares.

Thirty healthy individuals with no history of cardiovascular disease were studied to determine the electrocardiographic effects of maximal exercise immediately followed by ingestion of ice water. The subjects were subgrouped according to their training into (A) high (N = 5), (B) moderate (N = 14) and (C) low (N = 11) levels. Electrocardiograms (ECGs) were taken at rest and at rest with ingestion of ice water followed by maximal stress tests. Maximal stress tests were repeated followed by ingestion of ice water at the beginning of and at 2, 3, 6 and 9 minutes of recuperation. The stress test combining maximal effort and ice water ingestion was positive in all members of Group A, in 4 from Group B and in 1 from Group C. A stress test associating maximal effort with ice water ingestion is a useful method of detecting subjects susceptible to changes in ECG which appear to be secondary to coronary spasm. It has a low cost it is simple to perform and represents minimal risk.
