Bouts of exercise elicit discordant testosterone: cortisol ratios in runners and non-runners

ABSTRACT Objective: The testosterone:cortisol ratio (T:C) is suggested to be used in order to examine whether physical exercise generates either a "catabolic environment" or an "anabolic environment". The present study aims to evaluate the acute time-course profile of cortisol and testosterone due to an episode of physical exercise. A biphasic profile in the T:C ratio response was hypothesized. Materials and methods: Morning sessions of treadmill running at two different intensities (Heart Rate at 65% and 80% of the maximum cardiac reserve) were performed by 6 male non-runners (NR) and 12 trained male runners (subdivided into trained runners T1 and T2). Cortisol and testosterone were measured in saliva. NR and T1 ran for 30 minutes at both intensities, and T2 ran for 46 minutes (± 4.1) at 65% and 42 minutes (± 3.5) at 80%. Results: In the 80% heart rate target, both groups of runners showed the biphasic time-profile, while the non-runners group did not. However, at the 65% level, none of the groups presented the hypothesized biphasic response. Conclusions: A biphasic time-profile in the testosterone:cortisol ratio can be seen in short-bout, high intensity exercise (treadmill running) during the morning in men trained for this specific physical activity.

O atendimento da crise psicogênica nos prontos-socorros / Psychogenic seizure care in accident and emergency units

Este artigo analisa um aspecto da clínica médica e a rotina de acolhimento de doenças psicogênicas neste campo. A partir do fragmento de um caso de atendimento médico em pronto-socorro, observou-se um desmerecimento a pacientes com manifestações histéricas com somatização, consideradas pela equipe da instituição, ironicamente, como "emergências emocionais" ou "pitis". Tal comportamento reflete um problema clássico da deficiência de conhecimento sobre a medicina psicossocial, que se torna paradigmático nestes casos, onde há uma linha tênue entre o psíquico e o corporal. Para entender essa dinâmica, acreditamos que seja necessária uma incursão no contexto histórico do privilégio do diagnóstico racional, do discurso científico e suas influências no ensino médico contemporâneo.

This article investigates one part of medical practice and the routine of receiving psychogenic patients in that area. In one case at an accident and emergency unit, patients suffering hysterical somatization were pejoratively considered as "emotional emergencies" or "pitis" (a slang term for hysterical fit) by the health professionals, who questioned the need for medical care. Such behaviour reflects a classic problem of insufficient knowledge of psychosocial medicine, which forms the paradigmatic basis in such cases, where there is a fine line between the mental and the corporal. To understand this dynamic, we believe an investigation is required into the historical context of the centre stage given to rational diagnosis, scientific discourse and their influences on contemporary medical education.
