[Q]: Context: Food atopy patch tests (APTs) are considered a useful tool for the diagnosis of food allergy. Hypersensitivity to peanuts has not been investigated by means of APTs so far.', 'APTs and skin prick tests (SPTs) with peanuts were performed in 136 atopic dermatitis (AD) patients. Relevance of positive and negative responses to these tests was assessed by repeated open challenges with peanuts.', 'Nine percent of our AD patients reacted to the challenge. Positive responses to APTs were recorded in 19% of the patients, whereas in 12% positive SPTs were observed. APTs were more frequently positive in subjects with eczematous responses after challenge with respect to those with urticarial reactions. SPT reactivity proved to be higher in patients above 12 years of age, whereas APT positivity was more frequent in children under 6 years. APT sensitivity proved significantly higher than SPT sensitivity, in particular in children under 12 years of age. On the contrary, SPT specificity and positive predictive value were significantly higher with respect to those of APT in the age group of subjects under 6 years of age.
Answer: Our data suggest that APTs with peanuts may represent a useful integration to standard testing modalities employed for the diagnosis of peanut allergy in AD patients.

[Q]: Context: To test whether a brief mindfulness meditation training intervention buffers self-reported psychological and neuroendocrine responses to the Trier Social Stress Test (TSST) in young adult volunteers. A second objective evaluates whether pre-existing levels of dispositional mindfulness moderate the effects of brief mindfulness meditation training on stress reactivity.', 'Sixty-six (N=66) participants were randomly assigned to either a brief 3-day (25-min per day) mindfulness meditation training or an analytic cognitive training control program. All participants completed a standardized laboratory social-evaluative stress challenge task (the TSST) following the third mindfulness meditation or cognitive training session. Measures of psychological (stress perceptions) and biological (salivary cortisol, blood pressure) stress reactivity were collected during the social evaluative stress-challenge session.', 'Brief mindfulness meditation training reduced self-reported psychological stress reactivity but increased salivary cortisol reactivity to the TSST, relative to the cognitive training comparison program. Participants who were low in pre-existing levels of dispositional mindfulness and then received mindfulness meditation training had the greatest cortisol reactivity to the TSST. No significant main or interactive effects were observed for systolic or diastolic blood pressure reactivity to the TSST.
Answer: The present study provides an initial indication that brief mindfulness meditation training buffers self-reported psychological stress reactivity, but also increases cortisol reactivity to social evaluative stress. This pattern may indicate that initially brief mindfulness meditation training fosters greater active coping efforts, resulting in reduced psychological stress appraisals and greater cortisol reactivity during social evaluative stressors.

[Q]: Context: The present study tested the hypothesis that the anesthetic technique will influence the changes in regional blood flow (RBF) during intraoperative cardiac tamponade.', 'Twenty-four dogs were divided into three equal groups: Group I, anesthesia was maintained with ketamine (25 mg.kg(-1).hr(-1)); Group II, with fentanyl and midazolam (F-M; 10 mug.kg(-1).hr(-1) and 0.5 mg.kg(-1).hr(-1), respectively); Group III with 1 minimum alveolar concentration (MAC; 1.4%) isoflurane. Radioactive microspheres were used to measure RBF in myocardium, brain, spinal cord, abdominal viscera, skeletal muscle and skin. Cardiac output (CO) was measured by thermodilution and arterial pressure with a catheter situated in the thoracic aorta. Catheters were introduced into the pericardial cavity to infuse isotonic saline and to measure intrapericardial pressure (IPP). Measurements were obtained under control conditions and during tamponade, as defined by an increase in IPP sufficient to reduce mean arterial pressure by 40%.', 'Tamponade caused decreases in CO and RBF that were comparable under the three anesthetics, except that RBF in subcortical regions of the brain and in the spinal cord were maintained under isoflurane but decreased under ketamine or F-M.
Answer: In dogs, intraoperative cardiac tamponade caused comparable changes in RBF under the different anesthetic techniques except that autoregulation was effective in maintaining RBF within the central nervous system only under isoflurane anesthesia. Our findings provide no compelling reason to recommend one anesthetic over the others for maintenance of anesthesia in situations with increased risk for intraoperative cardiac tamponade. However, they cannot be extrapolated to anesthesia induction in the presence of cardiac tamponade.

Does isoflurane preserve central nervous system blood flow during intraoperative cardiac tamponade in dogs?
