Exercise has a direct positive impact on QoL in patients with cancer, during and following medical intervention. Exercise is a clinically relevant treatment and should be an adjunct to disease therapy in oncology.

BackgroundIntraoperative stimulation mapping (ISM) using electrocortical mapping (awake craniotomy, AC) or evoked potentials has become a solid option for the resection of supratentorial low-grade gliomas in eloquent areas, but not as much for high-grade gliomas. This meta-analysis aims to determine whether the surgeon, when using ISM and AC, is able to achieve improved overall survival and decreased neurological morbidity in patients with high-grade glioma as compared to resection under general anesthesia (GA).MethodsA systematic search was performed to identify relevant studies. Adult patients were included who had undergone craniotomy for high-grade glioma (WHO grade III or IV) using ISM (among which AC) or GA. Primary outcomes were rate of postoperative complications, overall postoperative survival, and percentage of gross total resections (GTR). Secondary outcomes were extent of resection and percentage of eloquent areas.ResultsReview of 2049 articles led to the inclusion of 53 studies in the analysis, including 9102 patients. The overall postoperative median survival in the AC group was significantly longer (16.87 versus 12.04 months; p < 0.001) and the postoperative complication rate was significantly lower (0.13 versus 0.21; p < 0.001). Mean percentage of GTR was significantly higher in the ISM group (79.1% versus 47.7%, p < 0.0001). Extent of resection and preoperative patient KPS were indicated as prognostic factors, whereas patient KPS and involvement of eloquent areas were identified as predictive factors.ConclusionsThese findings suggest that surgeons using ISM and AC during their resections of high-grade glioma in eloquent areas experienced better surgical outcomes: a significantly longer overall postoperative survival, a lower rate of postoperative complications, and a higher percentage of GTR.Electronic supplementary materialThe online version of this article (10.1007/s00701-018-3732-4) contains supplementary material, which is available to authorized users.

E-cadherins form intercellular junctions that maintain epithelial integrity. Epithelial integrity is impaired in asthma and can be restored by inhaled corticosteroids (ICSs). Our aim was to investigate the association of CDH1 gene polymorphisms (single-nucleotide polymorphisms (SNPs)) with airway remodelling, inflammation and forced expiratory volume in 1 s (FEV1) decline in asthma patients and assess whether ICSs modulate these effects.Bronchial biopsies of 138 asthmatics were available (population 1). Associations of 17 haplotype-tagging SNPs with epithelial E-cadherin expression, biopsy parameters and FEV1/vital capacity (VC) ratio were tested. FEV1 and VC data were collected in 281 asthmatics with 30-yr follow-up (population 2). Linear mixed-effect models were used to assess associations of SNPs with FEV1 decline.Seven out of the 17 SNPs were associated with airway remodelling, three with CD8+ T-cell counts, two with eosinophil counts and seven with FEV1 decline. All associations occurred only in patients using ICS. In general, alleles associated with less remodelling correlated with less FEV1 decline and higher FEV1/VC. Decreased epithelial E-cadherin expression was associated with five SNPs in non-ICS users.In conclusion, our data show that CDH1 polymorphisms are associated with epithelial Ecadherin expression and suggest that epithelial adhesion is an important contributor to airway remodelling and lung function in asthma. These effects are modified by the use of inhaled corticosteroids.

The aim of the present study was to establish the efficacy in terms of morbidity and health-related quality of life (HRQoL) of a group asthma education-exercise programme to children with low (below 10th percentile value) quality-of-life scores.A controlled, randomised, open, clinical trial was conducted. In total, 36 out of 53 unhappy children, among 204 (68%) respondents, treated in four paediatric practices, enrolled (mean age 10 yrs; range: 8-12 yrs), after random allocation in control and intervention groups (child, parent, teacher). Measurements were taken at baseline (T0) and after 3, 6 (T6) and 9 months (T9; intervention group only at 9 months). All but four controls completed the study.From T0-T6, changes (D) in HRQoL were clinically important and significantly greater in the intervention group than in the control group, both for generic HRQoL (effect size (ES) 0.95; D 16%¡12% versus -1¡4%) and for asthma-specific HRQoL (ES 0.58; D 15%¡17% versus 1.5¡14%). T9 measurements were consistent with T6 findings. Changes in sick days (ES 0.78), oral prednisone courses (ES 0.71) and doctor visits (ES 0.74) over a 6-month period were greater in the intervention group than in the control group. Changes could not be ascribed to change in lung function or medication.In unhappy children, quality of life and morbidity may improve with a low intensity asthma education-exercise programme, even without gains in pulmonary function or exercise tolerance.

One of the major challenges during glioblastoma surgery is balancing between maximizing extent of resection and preventing neurological deficits. Several surgical techniques and adjuncts have been developed to help identify eloquent areas both preoperatively (fMRI, nTMS, MEG, DTI) and intraoperatively (imaging (ultrasound, iMRI), electrostimulation (mapping), cerebral perfusion measurements (fUS)), and visualization (5-ALA, fluoresceine)). In this review, we give an update of the state-of-the-art management of both primary and recurrent glioblastomas. We will review the latest surgical advances, challenges and approaches that define the onco-neurosurgical practice in a contemporary setting and give an overview of the current prospective scientific efforts.
