The Spanish version of ACT is shown to be a reliable and valid tool for evaluating and discriminating asthma control.

This study was designed to provide information on correct use and preference to features and device handling of two multidose dry powder inhalers, the Diskus/Accuhaler and the Turbuhaler. A total of 169 powder-naive patients (mean age 40 years) with asthma or chronic obstructive pulmonary disease (COPD) were enrolled in a randomized crossover comparison of both inhalers. An effective use of either inhaler was assessed before (leaflet only) and after inhaler education. Ease of use especially during an attack and the presence of a dose counter were regarded as the most important features for an ideal inhaler. The percentage of correct handling maneuvers and the percentage of patients achieving 100% of correct maneuvers increased significantly (p < 0.001) after inhaler education in both devices, but percentage of correct use after the intervention was significantly higher for the Diskus/Accuhaler (92.6%) than for the Turbuhaler (89.8%; p = 0.036). Overall 60% of patients thought the Diskus/Accuhaler was preferable to the Turbuhaler (p < 0.001). The main reasons given were presence of a dose counter, perceived ease of use including ease of learning to use, design, and attached cover. Among those who preferred the Turbuhaler device, the main reason cited was small size, discreetness, and ease of holding. In the multivariate analysis, inhaler education (p = 0.005) and education level (p = 0.009) were significantly associated with the percentage of correct maneuvers. Age, sex, or tested inhaler showed no effect on appropriateness of the inhalation technique.

on behalf of the CAN Investigator Group { Summary. Objective: To develop and validate a questionnaire to assess asthma control in children (CAN). Design: Two versions of the CAN (for carers and children) were developed. Both versions were validated in an observational, prospective, multicenter study performed in 38 hospital outpatient clinics throughout Spain. Four hundred fifteen patients and their carers agreed to participate. Of these, 414 patients under 14 years old with frequent episodic or persistent (moderate to severe) asthma completed the questionnaire on 3 occasions (baseline, week 2, and week 12). For patients aged 2-8 the questionnaire was only completed by the carers, but for patients aged 9-14 the questionnaire was completed by the carers and the children. Clinician ratings of asthma control were used as a gold standard to assess the sensitivity, specificity, PPV and NPV of the new measure. Results: Evaluable responses were obtained from 215 carers for children aged 2-8 years and 199 children aged 9-14 years, and their parents. Using a questionnaire total score cut-off of 8 the patient version had a sensitivity of 76.3% and a specificity of 62.9%. For carer version these values were 73% and 69.7%, respectively. A cut point of 8 was selected to maximize the screening accuracy of the CAN questionnaire. Effect sizes in patients with clinician-rated improvements in asthma control were 0.33 and 0.57 for the carer and child versions, respectively. Conclusions: The screening accuracy and validity of the CAN questionnaire make it suitable for use in research and clinical practice. The sensitivity and specificity were close to 70%, which is acceptable for the study objective: obtain a tool to measure the level of asthma control.

Streptococcus agalactiae (Group B Streptococci, GBS) can cause severe neonatal sepsis. The recto-vaginal GBS screening of pregnant women and intrapartum antibiotic prophylaxis (IAP) to positive ones is one of the main preventive options. However, such a strategy has some limitations and there is a need for alternative approaches. Initially, the vaginal microbiota of 30 non-pregnant and 24 pregnant women, including the assessment of GBS colonization, was studied. Among the Lactobacillus isolates, 10 Lactobacillus salivarius strains were selected for further characterization. In vitro characterization revealed that L. salivarius CECT 9145 was the best candidate for GBS eradication. Its efficacy to eradicate GBS from the intestinal and vaginal tracts of pregnant women was evaluated in a pilot trial involving 57 healthy pregnant women. All the volunteers in the probiotic group (n = 25) were GBS-positive and consumed ~9 log10 cfu of L. salivarius CECT 9145 daily from week 26 to week 38. At the end of the trial (week 38), 72% and 68% of the women in this group were GBS-negative in the rectal and vaginal samples, respectively. L. salivarius CECT 9145 seems to be an efficient method to reduce the number of GBS-positive women during pregnancy, decreasing the number of women receiving IAP during delivery.
