ABSTRACT

Objetivou-se conhecer o significado da terminalidade da vida de pacientes oncológicos para médicos do Hospital das Clínicas Samuel Libânio (HCSL). Por metodologia tipo qualitativa exploratória e diretriz metodológica do discurso do sujeito coletivo, entrevistaram-se 20 médicos que cuidaram ou cuidam de pacientes oncológicos. Notou-se que o alívio da dor e a qualidade de vida são de suma importância para os cuidados paliativos. A terminalidade da vida é compreendida por esses profissionais apenas como a morte física do individuo e que existe algo além do viver humano – a metafísica do morrer.

This paper aimed to know the meaning of life terminality for physicians working at Hospital das Clínicas Samuel Libânio (HCSL) regarding oncologic patients. Through a qualitative and exploratory research, as well as methodological guidelines of the collective subject speech, 20 physicians who took care of oncologic patients were interviewed. It was observed that pain relief and life quality are extremely important in palliative care. These professionals understand that life terminality is just the physical death of a person, since there is some-thing beyond the human living – the metaphysics of dying.

ABSTRACT

INTRODUCTION AND OBJECTIVE: The heptapeptide angiotensin-(1-7) is a component of the renin-angiotensin system, which promotes many beneficial cardiovascular effects, including antithrombotic activity. We have recently shown that the antithrombotic effect of angiotensin-(1-7) involves receptor Mas-mediated NO-release from platelets. Here, we describe an orally active formulation based on angiotensin-(1-7) inclusion in cyclodextrin [Ang-(1-7)- CyD] as an antithrombotic agent. Cyclodextrins are pharmaceutical tools that are used to enhance drug stability, absorption across biological barriers and gastric protection. METHOD: To test the antithrombotic effect of Ang-(1-7)-CyD, thrombus formation was induced in the abdominal vena cava of spontaneously hypertensive rats that were pretreated either acutely or chronically with Ang-(1-7)-CyD. Male Mas-knockout and wild-type mice were used to verify the role of the Mas receptor on the effect of Ang-(1-7)-CyD. RESULTS: Acute or chronic oral treatment with Ang-(1-7)-CyD promoted an antithrombotic effect (measured by thrombus weight; all values are, respectively, untreated vs. treated animals) in spontaneously hypertensive rats (acute: 2.86 + 0.43 mg vs. 1.14 + 0.40 mg; chronic: 4.27 + 1.03 mg vs. 1.39 + 0.68 mg). This effect was abolished in Mas-knockout mice (thrombus weight in Mas wild-type: 0.76 + 0.10 mg vs. 0.37 + 0.02 mg; thrombus weight in Mas-knockout: 0.96 + 0.11 mg vs. 0.87 + 0.14 mg). Furthermore, the antithrombotic effect of Ang-(1-7)-CyD was associated with an increase in the plasma level of Angiotensin-(1-7). CONCLUSION: These results show for the first time that the oral formulation Ang-(1-7)-CyD has biological activity and produces a Mas-dependent antithrombotic effect.

ABSTRACT

Objetivou-se conhecer o significado da relação médico-paciente para alunos da Universidade do Vale do Sapucaí (Univas). Com método qualitativo do tipo exploratório e diretriz metodológica do discurso do sujeito coletivo, entrevistaram-se 60 alunos, do primeiro, segundo e sexto ano. Notou-se que os iniciantes entendem como relação médico- paciente uma relação de afinidade e afetividade, não havendo distinção entre patológico e emoções envolvidas. Ao fim do curso, nota-se que a postura do aluno complementa-se: consegue distinguir suas emoções e tratar de maneira eficiente o paciente. Pode-se afirmar que as reformas curriculares são fundamentais para a formação acadêmica, incluindo o ser humano como um ser psicossocial e não apenas portador de lesões ocultas. Encorajam-se estudos dessa natureza, que podem ser realizados com a intenção de ampliar o conhecimento de bioética na relação médico-paciente, estendendo-se a populações com características distintas em diferentes locais.


Se tuvo el objetivo conocer el significado de la relación médico-paciente para alumnos de la Universidade do Vale do Sapucaí (Univas). Con método cualitativo del tipo exploratorio y directriz metodológica del discurso del sujeto colectivo, se entrevistaron 60 alumnos, siendo éstos del primero, segundo y sexto año. Fue notado que los que están iniciando entienden como relación médico paciente una relación de afinidad y afectividad; no habiendo distinción entre patológico y emociones involucradas. Al final del curso, se nota que la postura del alumno se complementa; consigue distinguir sus emociones y tratar de manera eficiente al paciente. Se puede afirmar que las reformas curriculares son fundamentales para la formación académica, incluyendo al ser humano como un ser psicosocial y no solamente como portador de lesiones ocultas. Se incentivan estudios de esa naturaleza, que pueden ser realizados con la intención de ampliar el conocimiento de bioética en la relación médico-paciente, extendiéndose a poblaciones con características distintas en diferentes lugares.


One targeted to find the meaning of physician-patient relationship for students at the Universidade do Vale do Sapucaí (Univas). With the qualitative method of exploratory type and methodological guideline of the collective subject speech, sixty (60) students were interviewed, who were in the school?s first, second, and sixth years. It was noticed that beginners understand as physician-patient relationship an affinity and affectivity relationship, without distinction between the pathological and emotions involved. At the end of the course, it was observed that student?s stand was complemented, he is able to distinguish his emotions and care efficiently for the patient. One may state that curriculum reforms are fundamental for basic academic training, including the human being as a psychosocial being and not just a carrier of hidden lesions. Studies of this nature are encouraged that may be carried out with the intent of expanding bioethics knowledge in the physician-patient relationship, expanding it population with distinct features in different locations.
