    Control of stress-induced acth secretion by vasopressin and crh: additional evidence
    (Karger, 2016) Ramos, Adriana T. [UNIFESP]; Tufik, Sergio [UNIFESP]; Troncone, Lanfranco R. P.
    Vasopressin and CRH have complementary roles in the secretion of ACTH following different stress modalities. The concomitant use of V-1b and CRF1 receptor antagonists completely inhibits ACTH secretion in response to different stress modalities. The combination of the CRF1 antagonist SSR125543 with the V-1b antagonist SSR149415 effectively suppressed plasma ACTH 1.30 h after injection in rats stressed by ether vapor inhalation for 1 min, restraint stress for 1 h or forced swimming for 5 min. The duration of the effect was also studied. The CRF1 antagonist effectively suppressed ACTH secretion in restraint stress, while the V-1b antagonist was effective against ether inhalation. Both antagonists were necessary to block the forced swimming stress response. SSR125543 induced a prolonged effect and can be used in a model of prolonged HPA axis blockade. (C) 2016 S.

    Self-perception of knowledge and adherence reflecting the effectiveness of antiretroviral therapy
    (Brazilian Soc Urol, 2016) Dagli-Hernandez, Carolina; Lucchetta, Rosa Camila; de Nadai, Tales Rubens; Fernandez Galduroz, Jose Carlos [UNIFESP]; Mastroianni, Patricia de Carvalho
    Objectives: To evaluate which indirect method for assessing adherence best reflects highly active antiretroviral therapy (HAART) effectiveness and the factors related to adherence. Method: This descriptive, cross-sectional study was performed in 2012 at a reference center of the state of Sao Paulo. Self-report (simplified medication adherence questionnaire [SMAQ]) and drug refill parameters were compared to the viral load (clinical parameter of the effectiveness of pharmacotherapy [EP]) to evaluate the EP. The "Cuestionario para la Evaluacion de la Adhesion al Tratamiento Antiretroviral" (CEAT-VIH) was used to evaluate factors related to adherence and the EP and, complementarily, patient self-perception of adherence was compared to the clinical parameter of the EP. Results: Seventy-five patients were interviewed, 60 of whom were considered as adherent from the clinical parameter of the EP and ten were considered as adherent from all parameters. Patient self-perception about adherence was the instrument that best reflected the EP when compared to the standardized self-report questionnaire (SMAQ) and drug refill parameter. The level of education and the level of knowledge on HAART were positively correlated to the EP. Forgetfulness, alcohol use, and lack of knowledge about the medications were the factors most frequently reported as a cause of nonadherence. Conclusion: A new parameter of patient self-perception of adherence, which is a noninvasive, inexpensive instrument, could be applied and assessed as easily as self-report (SMAQ) during monthly drug refill, since it allows monitoring adherence through pharmaceutical assistance. Therefore, patient adherence to HAART could be evaluated using self-perception (CEAT-VIH) and the viral load test.
