- Aim:To explore the influence of personality traits and beliefs about medicines on adherence to treatment with asthma medication.Methods:Respondents were 35 asthmatic adults prescribed controller medication. They answered questionnaires about medication adherence, personality traits, and beliefs about medicines.Results:In gender comparisons, the personality traits “Neuroticism” in men and “adherence to medication” were associated with lower adherent behaviour. Associations between personality traits and beliefs in the necessity of medication for controlling the illness were identified. Beliefs about the necessity of medication were positively associated with adherent behaviour in women. In the total sample, a positive “necessity-concern” differential predicted adherent behaviour.Conclusion:The results imply that personality and beliefs about medicines may influence how well adults with asthma adhere to treatment with asthma medication.

Relationship of airway sensory hyperreactivity to asthma and psychiatric morbidity.

- Patients with airway symptoms induced by chemicals and odors are common in allergy clinics, but the problems cannot be explained by allergic or asthmatic reactions. Previous studies have shown that these patients often have increased sensitivity to inhaled capsaicin, which is known to reflect sensory reactivity; a diagnosis of airway sensory hyperreactivity (SHR) has been suggested for this condition.

- Introduction: Patients with "sensory hyperreactivity" (SHR) have airway environmental sensitivity, chronic cough and dyspnoea. Cough, chest discomfort and sense of difficulties getting air are some of the symptoms these patients seek medical attendance for. The patients have increased cough sensitivity to inhaled capsaicin, mediated by ion channel receptors on sensory nerves also known to react to pain stimuli. Whether a link exists between capsaicin airway sensitivity and pain sensitivity has not yet been evaluated. The aim was to investigate chest mobility, respiratory movement and pain sensitivity in SHR patients compared with patients with asthma, chronic obstructive pulmonary disease (COPD) and alleged healthy control subjects. Methods: Thirty-five patients diagnosed with SHR, 19 with COPD, 32 with asthma and 28 control subjects were included. Chest expansion was measured with a measuring tape and thoracic and abdominal movement with light sensors. Pain sensitivity was assessed using a pressure algometer. Results: Groups differed significantly in lung function, respiratory rate and pain sensitivity but also in chest expansion and abdominal breathing movement. In comparison with the control and asthma groups but not the COPD patients, SHR patients had an increased respiratory rate and reduced abdominal movement during deep breathing. All patient groups showed lower pain thresholds than the controls. Conclusion: Patients with SHR have evident signs of dysfunctional breathing and appeared to be most similar to the COPD group except for lung function. Lower pain thresholds among the patients indicate a general up-regulation of the sensory nerve system. (C) 2012 Elsevier Ltd. All rights reserved.

- OBJECTIVE: Antisecretory factor (AF) inhibits pathologic fluid secretion and inflammation. AF is expressed in most tissues and is secreted into the blood. Challenge with bacterial enterotoxins increases AF activity. The plasma level of active AF is also increased after intake of certain food constituents, such as specially processed cereals, SPC. The exact molecular events that mediate these responses have remained obscure. The objective of this study was to investigate changes in protein expression in liver after SPC diet. METHODS: Rats were fed SPC or standard rodent diet for 18 d. The induction of AF in plasma was tested by ELISA. Changes in the liver proteome were analyzed by using 2D DIGE and LC-MS/MS. Further characterizations were done with Western blot and immunohistochemistry studies. RESULTS: The AF activity was increased after intake of SPC. Equivalent to recombinant AF, 6.6 ± 1.09 ng/well could be detected in control plasma compared to 26 ± 5.73 ng/well in plasma after SPC treatment. We found that the protein level of glutathione S-transferase mu (GST mu) was significantly up-regulated 1.2-fold in rat liver after stimulation with SPC (wheat). The result was further confirmed by Western blot analysis. Immunohistochemistry showed staining for GST mu1 and AF preferentially in the central parts of the liver lobuli. CONCLUSION: Given the known role of GST mu1 in inducing defense, our results suggest that SPC-induced GST mu1 up-regulation can contribute to the positive clinical effects seen by SPC treatment.

- Background: Among patients with chronic unexplained cough, there is a recognized subgroup with respiratory symptoms induced by environmental irritants like chemicals and odours. The diagnosis of sensory hyperreactivity (SHR) has been suggested for this group of patients and can be made using a tidal breathing capsaicin inhalation test. The aim of the present study was to evaluate the ability of a single-breath, dose-response capsaicin threshold test to discriminate such patients from control subjects. Methods: A total of 46 patients with chronic cough and SHR who had previously shown a positive reaction in accordance with limits set for a tidal breathing capsaicin test were tested once with a single-breath, dose-response capsaicin cough threshold test, assessing capsaicin concentrations to evoke 2 (C2), 5 (C5) or 10 (C10) coughs. Twenty-nine subjectively healthy control subjects were also included and tested with the threshold method. Results: Patients had significantly lower C2, C5 and C10 in comparison to controls. From the results among patients and controls, sensitivity and specificity were calculated, and a receiver operating characteristic curve was constructed, showing excellent ability for C5 and C10 to discriminate patients from control subjects. Conclusions: For patients with SHR and chronic cough, capsaicin cough sensitivity was once again confirmed to be increased, in this case, using the single-breath dose-response method. Limits set for cough reactions regarded as more sensitive than normal can be useful in diagnostics and further research. C5 seems to be the best measure to use in research and differential diagnostics.

Bok (övrigt vetenskapligt/konstnärligt)abstract
- Vilken roll spelar förskolan för de yngsta barnens lärande? I den här boken presenterar sju forskare sina studier om vad som karakteriserar förskolan som lärandemiljö. I ett treårigt projekt har de undersökt olika förskolors pedagogiska kvalitet, föräldrars och lärares attityder till förskolan och barns lärande samt barns förståelse och agerande inom fyra områden: matematik, språk och kommunikation, samspel och flerspråkighet.
