Assessment of professional identity formation: a transcultural validation of the professional identity essay for brazilian portuguese.

INTRODUCTION: Professional identity formation (PIF) is recognized worldwide as an outcome of medical education grounded in the psychology of adult development and the literature on medical professionalism. However, instruments to assess and support PIF are scarce. The Professional Identity Essay (PIE) is an open-ended question assessment of PIF that elicits short narrative responses from learners and that can be analyzed to provide formative feedback and an overall stage of development. In this study, our aim was to translate and adapt the PIE to Brazilian Portuguese. METHODS: We followed a systematic procedure for the translation and cross-cultural adaptation of the instrument. A pilot study was conducted with medical students from the University of São Paulo. After providing individual formative feedback, we administered an online questionnaire to the Brazilian students to better understand the consequences of using the PIE. Content analyses of qualitative data were performed, we employ manifest content analysis, and the categories of analysis emerged from the participants' speeches. RESULTS: Students found the instrument's questions easy to interpret and self-reflective. It also gave students the opportunity to consider their PIF. The PIE was perceived as reliable and brought more awareness of the students' own processes in addition to a sense of capability to foster their own development. In the same way, the students emphasized the importance of being helped in this process. CONCLUSION: We found sufficient evidence of the validity of the PIE in terms of content, face validity, and consequences of use. The PIE enhances self-assurance in PIF through formative assessment and is sensitive to different cultures, making it a potential tool for educators.

Estudo comparativo entre o uso do antiagregante plaquetário e do anticoagulante oral na profilaxia de trombose em pacientes submetidos à operação cavopulmonar total com tubo extracardíaco: análise ecocardiográfica, angiotomográfica, cintilográfica, laboratorial e clínica / Comparative trial of the use of antiplatelet and oral anticoagulant in thrombosis prophylaxis in patients undergoing total cavopulmonary operation with extracardiac conduit: echocardiographic, tomographic, scintigraphic, clinical and laboratory analysis

Objetivo: Comparar a eficácia do AAS e da Varfarina na profilaxia da trombose em pacientes submetidos a operação cavopulmonar total. Avaliar se fatores de coagulação (VII, VIII e Proteína C), dados clínicos, fenestração ou fatores hemodinâmicos, interferem na trombose no pós-operatório. Métodos: Estudo prospectivo e randomizado de 30 pacientes, randomizados em Grupo I (Varfarina) e Grupo II (AAS), submetidos à derivação cavopulmonar total com tubo extracardíaco, entre 2008 e 2011, com seguimento de dois anos. Foram realizadas consultas clínicas que avaliavam efeitos colaterais e aderência. Realizado ecocardiograma transesofágico no pós-operatório imediato, 3, 6,12 e 24 meses; angiotomografia aos 6, 12 e 24 meses de pós-operatório para avaliação de alterações na parede interna do tubo ou trombos e cintilografia pulmonar, para avaliar possível TEP. Resultados: Dois óbitos no grupo I; 33,3% dos pacientes apresentaram trombo (46,7% no Grupo II). A ocorrência prévia de trombo e baixos níveis de proteína C da coagulação foram os únicos fatores que influenciaram no tempo livre de trombo (P=0,035 e 0,047). Avaliação angiotomográfica: 35,7% dos pacientes do grupo II tinham atapeteamento maior que 2 mm (P=0,082). Cintilografia: dois pacientes apresentaram TEP no grupo II. Cinco pacientes tiveram dificuldade de aderência, 4 no grupo I com INR variando de 1 a 6,4. Conclusão: A ocorrência prévia de trombo é um fator de risco para trombose no pós-operatório. Pacientes em uso de AAS tendem a depósito de material na parede do tubo. O número reduzido da amostra não permitiu concluir qual a droga mais eficaz na prevenção da trombose na população estudada. .

Objective: To compare the efficacy of aspirin and warfarin for prophylaxis of thrombosis in patients undergoing total cavopulmonary anastomosis. Evaluate whether coagulation factors (VII, VIII and protein C), clinical data, fenestration or hemodynamic factors, interfere with postoperative thrombosis. Methods: A prospective, randomized study of 30 patients, randomized into Group I (Warfarin) and Group II (AAS), underwent total cavopulmonary shunt with extracardiac conduit, between 2008 and 2011, with follow-up by clinical visits to evaluate side effects and adhesion. Performed transesophageal echocardiography in post operatory time, 3, 6,12 and 24 months; angiotomography at 6, 12 and 24 months to evaluate changes in the internal tube wall or thrombi and pulmonary scintigraphy to evaluate possible PTE. Results: Two deaths in group I; 33.3% of patients had thrombus (46.7% in Group II). The previous occurrence of thrombus and low levels of coagulation protein C were the only factors that influenced the time free of thrombus (P=0.035 and 0.047). Angiotomographic evaluation: 35.7% in group II presented material accumulation greater than 2 mm (P=0.082). Scintigraphy: two patients had PTE in group II. Five patients had difficulty to comply with the treatment, 4 in group I with INR ranging from 1 to 6.4. Conclusion: The previous occurrence of thrombus is a risk factor for thrombosis in the postoperative period. Patients using AAS tend to deposit material in the tube wall. The small sample size did not allow to conclude which is the most effective drug in the prevention of thrombosis in this population. .

Use of centrifugal pump and extracorporeal membrane oxygenation as cardiopulmonary support in pediatric cardiovascular surgery.

BACKGROUND: Extracorporeal membrane oxygenation is a well-documented resuscitation method in patients with severe hemodynamic and/or respiratory impairment. OBJECTIVE: To describe several aspects related to the use of extracorporeal membrane oxygenation in a pediatric heart center and determine its immediate and late outcomes. METHODS: Between October 2005 and January 2007, 10 patients who were submitted to pediatric cardiac surgery underwent extracorporeal membrane oxygenation implant. Median age was 58.5 days (40% neonates) and median body weight was 3.9 kg. Circulatory assistance was initiated aiming at the recovery and the weaning protocols followed daily clinical and echocardiographic criteria. Support was discontinued when transplant was contraindicated, when the patient was unable to recover or when survival was considered to be limited by a multidisciplinary team. RESULTS: Extracorporeal membrane oxygenation was employed after corrective or palliative heart surgery in 80% and preoperatively in the remaining ones. It was most often indicated for irresponsive hemodynamic instability (40%), post-cardiotomy shock (20%) and post-cardiac arrest (20%). The mean duration on support was 58 +/- 37 hours. Weaning was successfully in 50% of the cases and 30% were discharged home. Actuarial survival was 40%, 30% and 20% at 30 days, 3 months and 24 months, respectively. CONCLUSION: Extracorporeal membrane oxygenation is an effective and useful tool for the resuscitation of patients presenting severe hemodynamic and/or respiratory failure in the perioperative period of pediatric cardiovascular surgery.

FUNDAMENTO: O suporte cardiopulmonar com oxigenador de membrana é um método de ressuscitação de distúrbios hemodinâmicos, pulmonares ou ambos, consagrado em centros internacionais. OBJETIVOS: Descrever diversos aspectos relacionados ao suporte cardiopulmonar com oxigenador de membrana em um serviço de cirurgia cardiovascular nacional e determinar seus resultados imediatos e tardios. MÉTODOS: Entre outubro de 2005 e janeiro de 2007, 10 pacientes foram submetidos a suporte circulatório e/ou respiratório em candidatos ou submetidos a cirurgia cardiovascular pediátrica, com idade mediana de 58,5 dias (40 por cento de neonatos) e peso mediano de 3,9 kg. O suporte foi mantido com a intenção de recuperação e desmame, de acordo com critérios clínicos e ecocardiográficos diários. O suporte foi descontinuado nos pacientes sem indicação de transplante, com incapacidade de recuperação e com sobrevida limitada, de acordo com julgamento multidisciplinar. RESULTADOS: O suporte circulatório foi utilizado no pós-operatório de operações corretivas ou paliativas em 80 por cento e no pré-operatório no restante. Instabilidade hemodinâmica grave irresponsiva (40 por cento), falência miocárdica na saída de circulação extracorpórea (20 por cento) e parada cardíaca no pós-operatório (20 por cento) foram as indicações mais freqüentes. O tempo médio de permanência em suporte circulatório foi de 58 ± 37 horas. O suporte foi retirado com sucesso em 50 por cento e 30 por cento obtiveram alta hospitalar. A sobrevida atuarial foi de 40 por cento, 30 por cento e 20 por cento aos 30 dias, 3 meses e 24 meses, respectivamente. CONCLUSÃO: O suporte cardiopulmonar com oxigenador de membrana foi um método eficaz e útil na ressuscitação de distúrbios cardiovasculares e pulmonares graves no perioperatório de cirurgia cardiovascular pediátrica.
