BACKGROUND: Asthma treatment response is highly variable and pharmacogenetic markers that predict treatment response would be one step closer to personalized treatment. GWAS studies have shown that polymorphisms GLCCI1 could be associated with asthma treatment response to inhaled corticosteroids (ICS). MATERIAL AND METHODS: We genotyped rs37973 of GLCCI1 in 208 adult asthma patients treated with ICS. Change in % predicted FEV1 was analysed after short-term (3 months) and after long-term (at least 3 years) treatment...

Background: Antiprogrammed cell death-1/programmed cell death-ligand 1 (PD-1/PD-L1) therapies have demonstrated promising activity in advanced head and neck squamous cell carcinoma (HNSCC), with overall response rates of approximately 20% in unselected populations and survival benefit. Whether induction docetaxel, platinum and fluorouracil (TPF) modifies PD-L1 expression or tumour immune infiltrates is unknown. Patients and methods: Patients with locally advanced HNSCC treated at Gustave Roussy (Villejuif, France) between 2006 and 2013 by induction TPF followed by surgery were retrospectively considered...

INTRODUCTION: The overlap between asthma and chronic obstructive pulmonary disease (COPD) (ACO) has been discussed for many years but clinical recommendations for this entity have been diverse. This study is intended to reach a consensus on diagnosis, treatment and patient orientation for ACO, within the Portuguese medical community. METHODS: This study was conducted by a multidisciplinary panel of experts from three distinct medical specialties (Pulmonology, Family Medicine and Immunoallergology)...

Among the novelties described in the management of pulmonary disorders during the year 2017, we chose to describe three. First, the indication for inhaled glucocorticosteroids (ICS) in COPD has been revisited, because of their relationship with an increased occurence of pneumonia : ICS are now recommended only in severe COPD (GOLD D) with frequent exacerbations as second line treatment. Secondly, azithromycine has shown very promising results in poorly controlled severe asthma, with a significant impact on symptoms and exacerbations...

Traditional metrology has been unable to adequately address the needs of the emerging integrated circuits (ICs) at the nano scale; thus, new metrology and techniques are needed. For example, the reliability challenges in fabrication need to be well understood and controlled to facilitate mass production of through-substrate-via (TSV) enabled three-dimensional integrated circuits (3D-ICs). This requires new approaches to the metrology. In this paper, we use the microwave propagation characteristics to study the reliability issues that precede the physical damage caused by electromigration in the Cu-filled TSVs...

Long-acting β2-agonists (LABAs) such as formoterol and salmeterol are used for prolonged bronchodilatation in asthma, usually in combination with inhaled corticosteroids (ICSs). Unexplained paradoxical asthma exacerbations and deaths have been associated with LABAs, particularly when used without ICS. LABAs clearly demonstrate effective bronchodilatation and steroid-sparing activity, but long-term treatment can lead to tolerance of their bronchodilator effects. There are also concerns with regard to the effects of LABAs on bronchial hyperresponsiveness (BHR), where long-term use is associated with increased BHR and loss of bronchoprotection...

BACKGROUND: Transrectal ultrasound-guided prostate biopsy (TUPB) is associated with infectious complications (ICs), which are related to a greater prevalence of ciprofloxacin-resistant bacteria (CRB) in rectal flora. We examined the ICs that occurred in 2 groups: A guided antibiotic prophylaxis (GP) group and an empiric prophylaxis (EP) group. We assessed the financial impact of GP. MATERIAL AND METHODS: The GP group was studied prospectively (June 2013 to July 2014)...

BACKGROUND: The peripheral blood eosinophil count might help identify those patients with chronic obstructive pulmonary disease (COPD) who will experience fewer exacerbations when taking inhaled corticosteroids (ICS). Previous post-hoc analyses have proposed eosinophil cutoffs that are both arbitrary and limited in evaluating complex interactions of treatment response. We modelled eosinophil count as a continuous variable to determine the characteristics that determine both exacerbation risk and clinical response to ICS in patients with COPD...

Concurrent single-pulse TMS-EEG (spTMS-EEG) is an emerging noninvasive tool for probing causal brain dynamics in humans. However, in addition to the common artifacts in standard EEG data, spTMS-EEG data suffer from enormous stimulation-induced artifacts, posing significant challenges to the extraction of neural information. Typically, neural signals are analyzed after a manual time-intensive and often subjective process of artifact rejection. Here we describe a fully automated algorithm for spTMS-EEG artifact rejection...

Asthma is a pathologically heterogeneous disease, consisting of several phenotypes. Different types of airway inflammation are the cornerstone feature of this condition. Fraction of nitric oxide in exhaled air (FENO) has been proposed as a noninvasive, specific biomarker for eosinophilic airway inflammation and has been shown to be elevated in patients with allergic asthma phenotype. More recent studies indicate that FeNO identifies T-helper cell type 2 (Th2)-mediated airway inflammation with a high predictive value for identifying inhaled corticosteroid (ICS) responsive airway inflammation...

Deep learning methods applied to problems in chemoinformatics often require the use of recursive neural networks to handle data with graphical structure and variable size. We present a useful classification of recursive neural networks approaches into two classes, the Inner and Outer approach. The inner approach uses recursion inside the underlying graph, to essentially 'crawl' the edges of the graph, while the outer approach uses recursion outside the underlying graph, to aggregate information over progressively longer distances in an orthogonal direction...

We enrolled patients with confirmed sputum eosinophilia who had visited our tertiary referral hospital between 2012 and 2015. We evaluated the incidence and predictors of exacerbations in patients with nonasthmatic eosinophilic bronchitis (NAEB), and investigated predictors of improvement in eosinophilic inflammation in chronic airway diseases with or without persistent airflow limitation. In total, 398 patients with sputum eosinophilia were enrolled. Of these, 152 (38.2%) had NAEB. The incidence rate of exacerbations requiring treatment with antibiotics, systemic corticosteroids, or hospital admission was 0...

BACKGROUND: A substantial literature has established the role of the inner organizational setting on the implementation of evidence-based practices in community contexts, but very little of this research has been extended to the education sector, one of the most common settings for the delivery of mental and behavioral health services to children and adolescents. The current study examined the factor structure, psychometric properties, and interrelations of an adapted set of pragmatic organizational instruments measuring key aspects of the organizational implementation context in schools: (1) strategic implementation leadership, (2) strategic implementation climate, and (3) implementation citizenship behavior...

Independent components analysis (ICA) may be considered as one of the most established blind source separation techniques for the treatment of complex data sets in analytical chemistry. Like other similar methods, the determination of the optimal number of latent variables, in this case, independent components (ICs), is a crucial step before any modeling. Therefore, validation methods are required in order to decide about the optimal number of ICs to be used in the computation of the final model. In this paper, three new validation methods are formally presented...

Although chemical vapor deposition (CVD)-grown carbon nanotube (CNT) arrays are considered ideal materials for constructing high-performance field-effect transistors (FETs) and integrated circuits (ICs), a significant gap remains between the required and achieved densities and purities of CNT arrays. Here, we develop a directional shrinking transfer method to realize up to 10-fold density amplification of CNT array films without introducing detectable damage or defects. In addition, the method improves the film uniformity while retaining the perfect alignment and high carrier mobility of 1,600 cm2V-1s-1 of CVD-grown CNT arrays...

BACKGROUND: Patients with difficult-to-control asthma consume 50-60% of healthcare costs attributed to asthma and cost approximately five-times more than patients with mild stable disease. Recent evidence demonstrates that not all patients with asthma have a typical type 2 (T2)-driven eosinophilic inflammation. These asthmatics have been called 'T2-low asthma' and have a minimal response to corticosteroid therapy. Adjustment of corticosteroid treatment using sputum eosinophil counts from induced sputum has demonstrated reduced severe exacerbation rates and optimized corticosteroid dose...

Treatments for patients with metastatic or advanced urothelial carcinomas on progression after first line chemotherapy or unfit for cisplatin are currently limited. Atezolizumab (Tecentriq®) is a monoclonal antibody targeting PD-L1. The first of IMVIGOR 210 phase II trial (NCT02951767) investigated atezolizumab as front line treatment among 119 patients with metastatic urothelial cancer unfit for cisplatin. Response rate was 23% and median overall survival 15.9 months. The second cohort (NCT02108652) included 310 patients whose tumors were progressing after first line platinum-based chemotherapy...

In this paper, we describe the development of a novel method to detect oral bacteria by combining direct polymerase chain reaction (direct PCR) with an immunochromatographic strip (ICS), enabling the identification of saliva in forensic samples. Direct PCR was first used to directly amplify specific oral bacterial sequences (from Streptococcus sanguinis and Streptococcus salivarius) from swab samples, circumventing the need for tedious sample preparation steps such as cell lysis and DNA extraction and purification...
