[Q]: Studies on the safety of aprotinin in coronary artery surgery have given conflicting results. Therefore, we studied the possible link between perioperative aprotinin treatment and renal dysfunction in patients undergoing first-time coronary surgery with a high risk of bleeding.', 'We performed a matched cohort study, comparing 200 patients receiving high-dose aprotinin with 200 patients receiving tranexamic acid during primary isolated coronary surgery. Patients were matched according to age, sex, and presence of acute coronary syndrome. Primary outcome was fractional change in creatinine clearance. Secondary outcomes were other evaluations of postoperative renal function, mortality, stroke, reoperation for bleeding, and transfusion requirements.', 'The groups were similar in baseline characteristics except that triple-vessel disease and history of myocardial infarction were more prevalent in the aprotinin group. No significant differences were found in fractional change in creatinine clearance (-11% versus -12%, medians, p = 0.75) or any other assessments of postoperative renal function between the tranexamic acid and the aprotinin group. Adverse event rates were similar: early mortality (3.5% versus 4.5%, p = 0.80), stroke (1.5% versus 2%, p = 1.0), reoperation for bleeding (3.5% versus 2.5%, p = 0.77), and 5-year survival (87% versus 84%, p = 0.17). Patients in the aprotinin group received fewer transfusions (48% versus 60.5%, p = 0.02), fewer units of packed red blood cells (2.0 versus 1.4, p = 0.02) and plasma (1.3 versus 0.5, p < 0.001), but more units of platelets (0.1 versus 0.2, p = 0.02).

[Q]: Lung inflation causes cardiovascular suppression via an increase in intrathoracic pressure and neural mechanisms. To examine the mechanisms involved, we mea-sured the heart rate (HR) and arterial blood pressure (AP) responses to lung inflation before and after spraying the bronchi with lidocaine to suppress airway reflex. Thirty women participated in the study. One group (n = 20, Group BT) had their tracheas intubated by using double-lumen tubes. The other group (n = 10, Group TT) received an ordinary endotracheal tube. They were all studied under general anesthesia by using nitrous oxide, isoflurane, and muscle relaxation after a thiopental induction. In each patient, airway pressure was increased for 3 s, and changes in HR and AP were measured. Lung inflation was repeated after 5 mL of 4% lidocaine had been sprayed into the main bronchi unilaterally in Group BT or bilaterally in Group TT. There were no significant differences in cardiovascular responses between left and right lung inflation with the pressure at 20 and 30 cm H(2)O. Both lungs inflated at 20 cm H(2)O caused an increase in HR with a significantly greater decrease in AP than with unilateral inflation. Anesthesia of the bronchi abolished the HR increase, but not the AP decrease. Lung inflation at 30 cm H(2)O caused significant decreases in HR and AP which were not affected with topical anesthesia. These results indicate that the cardiovascular responses elicited by lung inflation in anesthetized humans are predominantly the direct effect of the increase in intrathoracic pressure, although sympathetic afferent activity induced via stimulation of mechanoreceptors in the airways contributes.

[Q]: Classical conditioning of the eyeblink reflex is a simple form of motor learning which depends on the integrity of the cerebellum. Acquisition of conditioned eyeblink responses is markedly reduced in patients with cerebellar disorders. Noninvasive transcranial direct current stimulation (tDCS) has been reported to modify the excitability of the cerebellar cortex.', 'The aim of the study was to assess whether acquisition of conditioned eyeblink responses (CR) is altered by cerebellar tDCS.', 'A standard delay conditioning paradigm with a 540 ms tone as conditioned stimulus (CS) coterminating with a 100 ms air puff as unconditioned stimulus (US) was used in a total of 30 healthy subjects (18 female, 12 male, mean age 23.4 ± 1.9 years). One hundred paired CS-US trials and 30 extinction CS alone trials were given. tDCS (2 mA intensity, ramp like onset) was applied over the right cerebellar hemisphere ipsilaterally to the US during the acquisition phase. Subjects were randomly assigned to three groups (n = 10) using anodal, cathodal or sham stimulation. The investigator as well as the participants was blinded to the stimulation modality.', 'CR acquisition was significantly enhanced by anodal tDCS (mean total CR incidence 73.4 ± 25.2%) and significantly reduced by cathodal stimulation (12.6 ± 17.2%) compared to sham stimulation (43.8 ± 24.1%). During anodal tDCS CR onset occurred significantly earlier, that is mean onset of responses was shifted closer to CS onset.
