RESUMO
Here, we report that increasing treatment with inhaled corticosteroids (ICS) in patients with not well-controlled asthma from a medium to a high dose results in a profound reduction of blood eosinophils (median fall in blood eosinophil concentrations from 560 to 320 cells/µL). Therefore, 'normal values' of blood eosinophils in patients with asthma need to be considered in view of the individual ICS doses of the patients. In addition, increases in the dose of ICS may result in blood eosinophil concentrations which would formally preclude treatment with biologics targeting the interleukin-5 pathway.

BACKGROUND: Healthcare-utilization data for multiple sclerosis (MS) are scarce in Germany. The Purpose of the study was to analyse administrative prevalence of MS, medication use and type of specialists involved in MS treatment in the outpatient setting in Bavaria. METHODS: Pseudonymized claims data from Bavarian Statutory Health Insurance (SHI)-accredited physicians were used. Administrative prevalence of MS was defined as having ≥1 MS diagnosis (International Classification of Diseases, 10th edition, code G35) documented by a neurologist or psychiatrist, or ≥1 prescription for disease-modifying drugs (DMDs)). The administrative prevalence calculated for Bavaria was projected to Germany. DMD prescription and involvement of different specialities in health care service for MS patients was analysed. RESULTS: Administrative prevalence of MS in Bavaria increased from 0.123% to 0.175% of insured persons between 2005 and 2009; when projected, this yielded ~102,000-143,000 patients with MS in the German population. The percentage of patients receiving ≥1 DMD prescription increased from 45.5% to 50.5%. Patients with MS were mainly treated by neurologists in the ambulatory care setting. CONCLUSIONS: These results provide important information on the administrative prevalence of MS in Bavaria and on healthcare provision for patients, which is relevant for resource planning in the healthcare sector.

BACKGROUND: Restriction of elbow mobility is a very frequent complaint after trauma or surgery. The objective of this study was to assess and compare the effectiveness of dynamic, static, or static-progressive bracing in patients with elbow stiffness of traumatic or postoperative origin and without evidence of ossification. For the purpose of this study, effectiveness was measured as the increase in total range of motion, as well as extension and flexion. MATERIALS AND METHODS: We performed a systematic search of the keywords "elbow AND (stiffness OR stiff) AND (brace OR splint OR conservative)" in the online databases PubMed, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Library. We included all clinical studies using dynamic or static bracing in patients with elbow stiffness. Eligible outcomes were changes in total range of motion, flexion, and extension; sustainability of results; and complications. RESULTS: We included 13 eligible studies, providing data on 14 treated groups in 247 patients. The mean age of these patients was 34.5 ± 10.4 years, and female patients comprised 46% ± 12%. The mean duration from the incident to the start of brace treatment was 6.9 ± 5.1 months. The mean improvement in range of motion during the course of treatment was 38.4° ± 8.9° (95% confidence interval, 39.5°-41.8°). CONCLUSIONS: The current evidence strongly supports the use of static-progressive stretching 3 times 30 minutes per day in each direction as a first line of treatment in patients with post-traumatic and postsurgical elbow stiffness. If this treatment fails or if reasons for stiffness other than soft-tissue incompliance are identified, further surgical interventions should be considered.

Genomic in situ hybridization (GISH) has been proved to be the most effective and accurate technique for confirmation of hybrid character. The objective of our study was to adapt and optimize a GISH protocol for identification of donor chromatin in hybrids obtained by interspecific crosses between five Rhododendron taxa (R. aureum, R. brachycarpum, R. catawbiense 'Catharine van Tol', R. catawbiense 'Nova Zembla', and R. yakushimanum 'Koichiro Wada'). Positive results were obtained only when we used mitotic chromosome spreads prepared from anthers. The best differentiation of maternal and paternal chromosomes in hybrid genomes was obtained when 50 ng of probe was applied together with blocking DNA at a concentration of 3.0 microg/microL. The results demonstrate that GISH is a practical tool for detection of alien genomes and analysis of the constitution of the chromosomes in rhododendron hybrids.

BACKGROUND: Breastfeeding is a well-known protective factor against severe respiratory tract infections. Recently, a gender specific role for human milk has been described in very low birth weight infants and neonates: breast milk protected girls but not boys. OBJECTIVE: To determine whether the protective effect of breastfeeding on the severity of acute respiratory infections in full term infants is different for girls and boys. METHODS: A prospective cross-sectional study of infants seeking medical care for acute respiratory infection. The protective role of breastfeeding against viral pneumonia and hospitalization were assessed by univariate and multivariate analyses. Analyses were adjusted for important confounders. RESULTS: A total of 323 patients were enrolled in this study. Breastfeeding protected girls against pneumonia and hospitalization, but did not protect boys. Nonbreastfeeding females were particularly susceptible to severe acute respiratory infections. CONCLUSIONS: Breastfeeding had a protective effect against severe disease in infant girls experiencing their first symptomatic respiratory infection. Nonbreastfeeding females are at significant risk for severe acute lung disease and should be targeted intensively by breastfeeding campaigns.

Adults of most marine benthic and demersal fish are site-attached, with the dispersal of their larval stages ensuring connectivity among populations. In this study we aimed to infer spatial and temporal variation in population connectivity and dispersal of a marine fish species, using genetic tools and comparing these with oceanographic transport. We focused on an intertidal rocky reef fish species, the shore clingfish Lepadogaster lepadogaster, along the southwest Iberian Peninsula, in 2011 and 2012. We predicted high levels of self-recruitment and distinct populations, due to short pelagic larval duration and because all its developmental stages have previously been found near adult habitats. Genetic analyses based on microsatellites countered our prediction and a biophysical dispersal model showed that oceanographic transport was a good explanation for the patterns observed. Adult sub-populations separated by up to 300 km of coastline displayed no genetic differentiation, revealing a single connected population with larvae potentially dispersing long distances over hundreds of km. Despite this, parentage analysis performed on recruits from one focal site within the Marine Park of Arrábida (Portugal), revealed self-recruitment levels of 2.5% and 7.7% in 2011 and 2012, respectively, suggesting that both long- and short-distance dispersal play an important role in the replenishment of these populations. Population differentiation and patterns of dispersal, which were highly variable between years, could be linked to the variability inherent in local oceanographic processes. Overall, our measures of connectivity based on genetic and oceanographic data highlight the relevance of long-distance dispersal in determining the degree of connectivity, even in species with short pelagic larval durations.

BACKGROUND: Shoulders of throwing and swimming athletes are highly stressed joints that often show structural abnormalities on magnetic resonance imaging (MRI). However, while water polo players exhibit a combination of throwing and swimming movements, a specific pattern of pathological findings has not been described. PURPOSE: To assess specific MRI abnormalities in shoulders of elite water polo players and to compare these findings with a healthy control group. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: After performing a power analysis, volunteers were recruited for this study. Both shoulders of 28 semiprofessional water polo players and 15 healthy volunteers were assessed clinically (based on the Constant score) and had bilateral shoulder MRIs. The shoulders were clustered into 3 groups: 28 throwing and 28 nonthrowing shoulders of water polo athletes and 30 shoulders of healthy control subjects. RESULTS: Twenty-eight male water polo players with an average age of 24 years and 15 healthy subjects (30 shoulders) with an average age of 31 years were examined. Compared with controls, significantly more MRI abnormalities in the water polo players' throwing shoulders could be found in the subscapularis, infraspinatus, and posterior labrum (P = .001, P = .024, and P = .041, respectively). Other structures showed no statistical differences between the 3 groups, including the supraspinatus tendon, which had abnormalities in 36% of throwing versus 32% of nonthrowing shoulders and 33% of control shoulders. All throwing shoulders showed abnormal findings in the MRI, but only 8 (29%) were symptomatic. CONCLUSION: The shoulders of semiprofessional water polo players demonstrated abnormalities in subscapularis and infraspinatus tendons that were not typical abnormalities for swimmers or throwing athletes. CLINICAL RELEVANCE: The throwing shoulders of water polo players have specific MRI changes. Clinical symptoms do not correlate with the MRI findings.
