RESUMO

BACKGROUND: Emotional intelligence (EI) and assertiveness are key abilities for physiotherapists. Clinical placements seem to affect students' development of EI and assertiveness, and their construction of the professional role. PURPOSE: This study aims to compare the EI of physiotherapy students with students from other health professions and explore the evolution of EI and assertiveness in physiotherapy students throughout their university education, focusing on the influence of clinical practice. METHOD: Students (N = 753) completed a self-administered questionnaire to measure emotional intelligence (TMMS 24), assertiveness (CSES), and sociodemographic variables. RESULTS: EI levels were adequate and very similar across the three disciplines. Regarding assertiveness, physiotherapy students in year 4 obtained significantly higher levels than students in years 1, 2, and 3. Significant correlations (rs (207) = 0.35, p < .001) were found between assertiveness and the number of modules of clinical practice. CONCLUSION: This study contributes with further evidence on the improvement of assertiveness in physiotherapy students through their university education and, in particular, with clinical placements. Practical implications highlight the importance of training in EI and assertiveness during university, coupled with clinical placements, in order to prepare for an effective and satisfactory professional life.

RESUMO

El uso de la escritura creativa basada en la Medicina Narrativa (MN) como aprendizajeactivo para la enseñanza del rol profesional en Ciencias de la Salud, ha despertado interés en losúltimos años. Se realizó una revisión sistemática exploratoria para conocer la eficacia de su aplica-ción en estudiantes universitarios del ámbito de las ciencias sociales y de la salud. Los estudiosfueron recuperados de WoS, Scopus, Dialnet y REDIB. El análisis de 8 artículos seleccionados des-cribió esta metodología como herramienta útil para fomentar las voces narrativas de los estudiantes,impulsar la reflexión sobre encuentros clínicos, fomentar la atención clínica atenta y empática yfacilitar la gestión emocional. Esta metodología permite además el desarrollo de destrezas del len-guaje, creatividad y espontaneidad en la construcción de la identidad profesional y sobre el profe-sionalismo. A pesar de la escasez de estudios, parece prometedora su utilidad a nivel curricular,aunque se precisa analizar con profundidad el fenómeno de estudio.(AU)

RESUMO

Physical and psychological demands from gymnastics increase the occurrence of injuries and pain among athletes, whose consequent level of catastrophizing could affect rehabilitation and performance. Although the characteristics of each gymnastics discipline may be key factors, they remain unclear. This study aimed to describe injuries, pain, and catastrophizing levels of gymnasts, according to their discipline and training characteristics. A total of 160 gymnasts fulfilled an online survey at the end of the 2021 season. Eighty gymnasts sustained 106 injuries (mainly ankle), and 128 had current pain (mainly low back). Although results were similar among disciplines, rhythmic gymnasts had a higher prevalence of low back pain (p = 0.003) and artistic wrist pain (p = 0.011). Gymnasts who sustained an injury displayed higher hours of training (p = 0.026), and those with current pain had more sports experience (p = 0.001) and age (p < 0.001). A higher catastrophizing level was observed in injured gymnasts and correlated with pain level (p < 0.001). No other differences were found (p > 0.05). Pain and injury prevalence is extremely high among gymnasts, being specific to the gymnastics discipline and increasing catastrophizing experience. Hours of training, age, and sports experience are key related factors, regardless of discipline.

RESUMO

Tyrosinase starts melanogenesis and determines its course, catalyzing the oxidation by molecular oxygen of tyrosine to dopa, and that of dopa to dopaquinone. Then, nonenzymatic coupling reactions lead to dopachrome, which evolves toward melanin. Recently, it has been reported that d-tyrosine acts as tyrosinase inhibitor and depigmenting agent. The action of tyrosinase on the enantiomers of tyrosine (l-tyrosine and d-tyrosine) and dopa (l-dopa and d-dopa) was studied for the first time focusing on quantitative transient phase kinetics. Post-steady-state transient phase studies revealed that l-dopachrome is formed more rapidly than d-dopachrome. This is due to the lower values of Michaelis constants for l-enantiomers than for d-enantiomers, although the maximum rates are equal for both enantiomers. A deeper analysis of the inter-steady-state transient phase of monophenols demonstrated that the enantiomer d-tyrosine causes a longer lag period and a lower steady-state rate, than l-tyrosine at the same concentration. Therefore, d-melanogenesis from d-tyrosine occurs more slowly than does l-melanogenesis from l-tyrosine, which suggests the apparent inhibition of melanin biosynthesis by d-tyrosine. As conclusion, d-tyrosine acts as a real substrate of tyrosinase, with low catalytic efficiency and, therefore, delays the formation of d-melanin.

RESUMO

Communication and interpersonal skills are relevant to the health professions, so it is important to promote these competencies at university. This research assesses the effectiveness of teaching oral competence through simulation using face-to-face and blended methods. A public speaking workshop was conducted in a group of 144 first year nursing students. Three groups were obtained according to the teaching method (Group 1: traditional method-3 sessions, Group 2: traditional method-2 sessions, Group 3: blended method-2 sessions). Public speaking confidence was measured at the beginning and end of the training, and oral competence was assessed at the end. As a result, all groups achieved a good level of oral competence after the training. However, while students in Group 1 showed greater oral competence, with regard to confidence in public speaking, students in Group 1 showed significantly worst results than those in Group 3. We concluded that simulation is a useful strategy to improve cognitive learning, and behavioural and practical competencies such as public speaking. As for the teaching method, although blended learning did not offer better results than traditional learning, it seems useful provide there is at least one face-to-face session so that the student can perform a speech and receive corrective feedback.

RESUMO

To assess the opinion and the level of satisfaction of patients concerning analgesia during external cephalic version (ECV), we present the results of a survey of 120 women undergoing ECV at term during a randomised controlled trial (July 2012 to February 2013) comparing remifentanil and nitrous oxide. Overall, 110 (91.7%) women said they would repeat the procedure and 111 (92.5%) that they would recommend it to another pregnant woman, with no significant differences by type of analgesia. The administration and sense of comfort were rated better in the remifentanil group (p < .01). In conclusion, the use of analgesia during ECV is associated with a high rate of willingness among women to repeat the procedure and recommend it to other pregnant women.Impact statementWhat is already known on this subject? ECV is commonly a painful manoeuvre for the woman. This pain triggers maternal reactive abdominal muscle contraction and involuntary abdominal tensing, reducing the likelihood of successful version and causing some women to reject the technique.What do the results of this study add? The use of analgesia during ECV is associated with a high rate of willingness among women to repeat the procedure and recommend it to other pregnant women. The sense of comfort during ECV was also significantly better in the remifentanil group, probably because of its greater analgesic power and greater comfort during its administration.What are the implications of these findings for clinical practice and/or further research? ECV should be carried out under analgesia, when available, not only to decrease pain but also to encourage wider adoption of the technique and enable more women to benefit from it.

RESUMO

Se presenta un caso clínico donde la paciente manifiesta una sintomatología derivada del incumplimiento del régimen terapéutico prescrito para las úlceras vasculares que presenta en ambos miembros inferiores. Tras la valoración, se determina que los factores asociados al incumplimiento son el desencadenante de los síntomas referidos, revisándose y modificándose el plan de cuidados establecido. Con esta actuación se contribuyo a la evolución favorable de las lesiones y a un mayor control del tratamiento por parte de la paciente. Se debe reconocer todos los factores que influyen en la atención a la población y del manejo del lenguaje enfermero. El cuidado holístico debe primar en la atención enfermera, de manera que permita detectar este tipo de situaciones y planificar las actuaciones concretas para cada problemática de cada persona.


A clinical case is presented where the patient manifests a symptomatology derived from non-compliance with the prescribed therapeutic regimen for vascular ulcers presented in both lower limbs. After the assessment, it is determined that the factors associated with non-compliance are the trigger of the referred symptoms, reviewing and modifying the established care plan. This action contributed to the favorable evolution of the lesions and to a greater control of the treatment by the patient. All factors that influence population care and nursing language management must be recognized. Holistic care should take priority in nursing care, so that it can detect these types of situations and plan specific actions for each problem of each person.

RESUMO

La autoestima es una parte del autoconcepto. Contar con niveles óptimos significa sentirse útil, capaz y poder hacer uso de habilidades y destrezas. El estatus y rol que desempeñe la persona en la sociedad, están íntimamente relacionados con la autoestima. Diferentes universidades españolas han pretendido con programas formativos, acercar la universidad a la sociedad e intentar contemplar la formación de las personas mayores como herramienta útil de participación social. En este contexto, el objetivo de este trabajo es estudiar los niveles de autoestima en alumnos mayores de la Universitat Oberta per a Majors (UOM) de la Universitat de les Illes Balears (UIB) y sus implicaciones. Se realizó un estudio descriptivo transversal con 96 alumno/as mayores mediante un cuestionario de auto-informe (García Monge, 1998) administrado grupalmente. Los resultados obtenidos muestran diferencias estadísticamente significativas entre el Yo Real y el Yo Ideal, lo que implica la presencia de niveles bajos de autoestima. Además, el análisis correlacional apunta la existencia de relaciones significativas entre autoestima y género. A partir de estos resultados, se analizan posibles factores relacionados con la autoestima y se proponen estrategias para mejorarla


Self-esteem is a part of the self-concept. Having optimal levels means feeling useful, capable and able to make use of skills and abilities. The status and role which the person in society, are closely related to self-esteem. Different Spanish universities have sought to training programs, university closer to society and try to see training as a useful tool for social participation. The aim of this paper is study levels of self-esteem in students over Universitat Oberta per a Majors (UOM) of Universitat de les Illes Balears (UIB) and its implications. Cross-sectional study of 96 students / older has been made by a self-report questionnaire (García Monge, 1998). Results show statistically significant differences between the Real I and the Ideal I, that indicate low self-esteem. The correlations suggest existence of significant relationships between self-esteem and gender. Factors related with self-esteem and propose improvement strategies are suggested

RESUMO

Pain assessment is difficult in individuals with cerebral palsy (CP). This is of particular relevance in children with communication difficulties, when non-verbal pain behaviors could be essential for appropriate pain recognition. Parents are considered good proxies in the recognition of pain in their children; however, health professionals also need a good understanding of their patients' pain experience. This study aims at analyzing the agreement between parents' and physiotherapists' assessments of verbal and non-verbal pain behaviors in individuals with CP. A written survey about pain characteristics and non-verbal pain expression of 96 persons with CP (45 classified as communicative, and 51 as non-communicative individuals) was performed. Parents and physiotherapists displayed a high agreement in their estimations of the presence of chronic pain, healthcare seeking, pain intensity and pain interference, as well as in non-verbal pain behaviors. Physiotherapists and parents can recognize pain behaviors in individuals with CP regardless of communication disabilities.

RESUMO

OBJECTIVE: To determine the number of potential deceased organ donors from out-of- hospital cardiac arrest cases (OHCA) attended by public physician-led emergency medical services in Spain, based on data recorded in the nationwide Spanish OHCA Registry (OHSCAR). MATERIAL AND METHODS: We analysed OHSCAR data on deceased OHCA patients in Spain during 13 months (1/10/2013 to 31/10/2014). Variables included age, sex, estimated OHCA time, cardiopulmonary resuscitation (CPR) start time and outcome. Inclusion criteria were: age 16-60 years, witnessed OHCA, no return of spontaneous circulation (ROSC) and time interval <15min between OHCA occurrence and CPR initiation. RESULTS: Of a total 8789 cases, 3290 met the age criteria; of these, CPR was not witnessed in 745 cases. Among the remaining 2545 patients, 141 were included in uncontrolled donation after cardiac death (uDCD) programs, 902 arrived at the hospital with ROSC, 64 arrived with ongoing CPR and 15 cases were lost to follow-up. Of the remaining 1423 without ROSC, CPR initiation time was not recorded in 454 cases and 398 did not meet the time criteria <15min between OHCA and CPR initiation. Finally, 571 met all the criteria and could have been potential donors. There were significant differences in the actual donors percentage from potential donors percentage between provinces with and without donor programs (141/322=43.8% versus 0/390=0%), but there were no differences in ROSC between the two types of provinces (418/1320=31.7% versus 652/1970=33.4%). CONCLUSIONS: Many potential donors are missed in current clinical practice. uDCD programs are few and underused even in a country with high rates of organ transplantation.

RESUMO

INTRODUCTION: 3D laparoscopy allows the surgeon to regain the sense of depth and improve accuracy. The aim of the study was to assess the impact of 3D in bariatric surgery. PATIENTS AND METHODS: A retrospective cohort study was conducted. All our patients who underwent bariatric surgery (sleeve gastrectomy (SG) or gastric bypass (GB)) between 2013 and 2016 were included. We compared 3D laparoscopy cohort and 2D laparoscopy cohort. Variables are as follows: age, sex, DM, hypertension, surgeon experience, and type of intervention. Comparisons of operative time, hospital stay, conversion, complications, reoperation, and exitus are completed. RESULTS: Three hundred twelve consecutive patients were included. 56.9% of patients underwent GB and 43.1% SG. Global complications were 3.2% (fistula 2.5%, hemoperitoneum 0.3%, others 0.4%). One hundred four procedures were performed in the 3D cohort and 208 in the 2D cohort. The 2D cohort and 3D cohort were similar regarding the following: percentage of GB vs SG, age, gender, learning curve, diabetes mellitus 2, hypertension, and sleep apnea. The operating time and hospital stay were significantly reduced in the 3D cohort (144.07 ± 58.07 vs 172.11 ± 76.11 min and 5.12 ± 9.6 vs 7.7 ± 13.2 days. It was the same when we stratified the sample by type of surgery or experience of the surgeon. Complications were reduced in the 3D cohort in the surgeries performed by novice surgeons (10.2 vs 1.8%, p = 0.034). CONCLUSIONS: The use of 3D laparoscopy in bariatric surgery in our center has helped reducing the operating time and hospital stay, and improving the safety of the surgery, either in GB or SG, being equally favorable in novice or more experienced surgeons.

RESUMO

The next generation of lithium ion batteries (LIBs) with increased energy density for large-scale applications, such as electric mobility, and also for small electronic devices, such as microbatteries and on-chip batteries, requires advanced electrode active materials with enhanced specific and volumetric capacities. In this regard, silicon as anode material has attracted much attention due to its high specific capacity. However, the enormous volume changes during lithiation/delithiation are still a main obstacle avoiding the broad commercial use of Si-based electrodes. In this work, Si-based thin film electrodes, prepared by magnetron sputtering, are studied. Herein, we present a sophisticated surface design and electrode structure modification by amorphous carbon layers to increase the mechanical integrity and, thus, the electrochemical performance. Therefore, the influence of amorphous C thin film layers, either deposited on top (C/Si) or incorporated between the amorphous Si thin film layers (Si/C/Si), was characterized according to their physical and electrochemical properties. The thin film electrodes were thoroughly studied by means of electrochemical impedance spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, and atomic force microscopy. We can show that the silicon thin film electrodes with an amorphous C layer showed a remarkably improved electrochemical performance in terms of capacity retention and Coulombic efficiency. The C layer is able to mitigate the mechanical stress during lithiation of the Si thin film by buffering the volume changes and to reduce the loss of active lithium during solid electrolyte interphase formation and cycling.

RESUMO

The use of microalgae for biomethane production has been considerably increasing during the recent years. In this study, four dominant species belonging to the genera Scenedesmus, Chlorella, Dunaliella and Nostoc were selected. The influence of different genera with several morphological, structural and physicochemical characteristics on methane production was assessed in biochemical methane potential (BMP) tests. The ultimate methane yield values were 332 ± 24, 211 ± 2, 63 ± 17 and 28 ± 10 mL CH4/g VSadded for Scenedesmus obliquus, Chlorella sorokiniana, Dunaliella salina and Nostoc sp., respectively. The highest methane production was achieved by microalga species that had no complex cell wall or wall basically composed by proteins and simple sugars such as in S. obliquus, whereas lower methane yields were found for D. salina and Nostoc sp., due to the salinity effects and cell wall composition in terms of complex polysaccharide and glycolipid layers, respectively. Kinetic constant values obtained in the BMP tests ranged between 1.00 ± 0.08 and 0.097 ± 0.005 days(-1) for D. salina and S. obliquus, respectively.

RESUMO

INTRODUCTION: Our objective was to compare the effect of two pain relief methods (remifentanil vs. nitrous oxide) on the success rate of external cephalic version. MATERIAL AND METHODS: We conducted a randomized open label parallel-group controlled single-center clinical trial with sequential design, at Cruces University Hospital, Spain. Singleton pregnancies in noncephalic presentation at term that were referred for external cephalic version were assigned according to a balanced (1:1) restricted randomization scheme to analgesic treatment with remifentanil or nitrous oxide during the procedure. The primary endpoint was external cephalic version success rate. Secondary endpoints were adverse event rate, degree of pain, cesarean rate and perinatal outcomes. RESULTS: The trial was stopped early after the second interim analysis due to a very low likelihood of finding substantial differences in efficacy (futility). The external cephalic version success rate was the same in the two arms (31/60, 51.7%) with 120 women recruited, 60 in each arm. The mean pain score was significantly lower in the remifentanil group (3.2 ± 2.4 vs. 6.0 ± 2.3; p < 0.01). No differences were found in external cephalic version-related complications. There was a trend toward a higher frequency of adverse effects in the remifentanil group (18.3% vs. 6.7%, p = 0.10), with a significantly higher incidence rate (21.7 events/100 women vs. 6.7 events/100 women with nitrous oxide, p = 0.03). All reported adverse events were mild and reversible. CONCLUSIONS: Remifentanil for analgesia decreased external cephalic version-related pain but did not increase the success rate of external cephalic version at term and appeared to be associated with an increased frequency of mild adverse effects.

RESUMO

The dropout of university studies is a main concern in many countries, also for Health Sciences degrees. The reviews on dropout in all university degrees as well as nursing generally show multidimensional causes with factors related both to institutional and students' characteristics. Regarding the personal variables of students, researchers have focused on financial, family and personality features. Far less attention has been devoted to emotional variables. This study aims to explore whether individual variables of the emotional domain such as perceived emotional intelligence, dispositional optimism/pessimism and depressive rumination are related and/or can predict students' intention to dropout and academic performance. Using a cross-correlational approach, data were obtained from a sample of 144 nursing students. Students with a pessimistic disposition revealed a greater tendency to drop out. The remaining variables correlated significantly with pessimism but had no predictive value on dropout. Our results suggest that students with low levels of emotional clarity and repair and high depressive rumination have pessimistic expectations, so they are more likely to leave studies. No significant results were found in relation to academic performance. We conclude with an identification of strategies to increase retention and academic success.

RESUMO

El síndrome de Tako-Tsubo también se conoce como miocardiopatía de estrés o apical ballooning. Se corresponde con las características clínicas, analíticas, electrocardiográficas y ecocardiográficas de un síndrome coronario agudo, pero en el que la ausencia de obstrucciones significativas en las arterias coronarias, junto a la posterior recuperación total del ventrículo, aseguran el diagnóstico. No está exenta de complicaciones, aunque generalmente cursa con buen pronóstico. En nuestro artículo presentamos el caso clínico de una trabajadora, en la que una situación estresante desencadena el cuadro


The Tako-Tsubo syndrome is also known as stress cardiomyopathy or apical ballooning. It corresponds to the clinical, analytical, electrocardiographic and echocardiographic acute coronary syndrome, in which the lack absence of significant blockages in the coronary arteries, with the subsequent full recovery of the ventricle, ensures the diagnostic. Although it is not a complication-free diagnostic, it usually evolves with good prognosis. In our article we talk about a female worker with a stressful situation which triggers the symptom

RESUMO

La violencia interna en el lugar de trabajo es la que tiene lugar entre los trabajadores, incluidos mandos y directivos. Incluye la violencia física, el acoso sexual y el acoso psicológico, abarcando también otras conductas de violencia psicológica diferenciadas de éste. Debe ser considerada como un riesgo psicosocial, que supone un peligro importante para la salud y seguridad de las personas, y tiene repercusiones organizacionales a través de costes directos e indirectos. Considerar la violencia interna con este enfoque de riesgo laboral, supone que su abordaje se ha de realizar aplicando los principios de la acción preventiva, a la vez que permite adoptar estrategias de actuación dirigidas a la prevención del fenómeno. Las principales organizaciones a nivel mundial y nacional proponen la implementación de una política de prevención de la violencia en el lugar de trabajo. Este artículo trata sobre la conveniencia del desarrollo e implementación en las organizaciones de una política de prevención de la violencia interna, de carácter integral e integrado, que involucre a toda la organización, orientada a lograr entornos de trabajo más saludables y con un enfoque centrado en los factores organizativos y psicosociales. En el artículo se contemplan las premisas esenciales de esa política preventiva de la violencia interna, abordándose también los momentos básicos de la estrategia preventiva:—— La evaluación de riesgo psicosociales.—— La política de buenas prácticas.—— Los procedimientos de gestión de conflictos y acoso psicológico en el trabajo.—— Las estrategias de comunicación organizacional y las acciones formativas. Para conseguir auténtica efectividad, las políticas de prevención de la violencia interna deben incorporarse al Sistema de Gestión de la Prevención de la organización, que, a su vez, estará integrado en todos los sistemas de gestión restantes de la empresa (AU)


Internal violence in the workplace is that which happens between coworkers, including middle management and high command. It includes physical violence and sexual and psychological harassment, as well as other psychological violent conducts different from that. It must be considered as a psychosocial risk which involves important danger for people’s health and safety as well as organizational repercussions through direct and indirect costs. Considering internal violence from the “work risk” point of view means that it should be approached using the preventive action principles while it also allows the adoption of active strategies directed to prevent the phenomenon. Main national and international organizations propose to implement policies to prevent violence in the work place. This article deals with the convenience of the development and implementation in organizations of an internal violence prevention policy, which involves all the organization, orientated to achieve healthy workplace environments focused on organizational and psychosocial factors. This article approaches the essential premises of internal violence prevention policies, dealing as well with the basic moments of the preventive strategy:—— psychosocial risks evaluation—— good practice policy—— procedures for management of conflicts and psychological harassment at work—— organizational communication strategies and formative actions To accomplish actual effectiveness, the internal violence prevention policies must be incorporated to the organization’s Prevention Management System, which will at the same time, be integrated in all the rest of the management systems of the company (AU)
