The Icatibant Outcome Survey (IOS) is an observational study monitoring safety and effectiveness of icatibant in the real-world setting. We analyzed safety data from 3025 icatibant-treated attacks in 557 patients (enrolled between July 2009 and February 2015). Icatibant was generally well tolerated. Excluding off-label use and pregnancy, 438 patients (78.6%) did not report adverse events (AEs). The remaining 119 (21.4%) patients reported 341 AEs, primarily gastrointestinal disorders (19.6%). Of these, 43 AEs in 17 patients (3...

How Quaternary climatic and geological disturbances influenced the composition of Neotropical forests is hotly debated. Rain fall and temperature changes during and/or immediately after the Last Glacial Maximum (LGM) are thought to have strongly affected the geographical distribution and local abundance of tree species. The paucity of the fossil records in Neotropical forests prevents a direct reconstruction of such processes. To describe community-level historical trends in forest composition, we turned therefore to inferential methods based on the reconstruction of past demographic changes...

BACKGROUND: Guidelines and position papers indicate that allergen immunotherapy (AIT) is the only disease-modifying treatment, including prevention of the onset of new allergen sensitizations. However, this preventive effect was shown by only a few observational studies. Our aim was to systematically review the efficacy of AIT in preventing the onset of new allergen sensitizations. METHODS: Computerized bibliographic searches of MEDLINE, EMBASE, and the Cochrane Library (through June 2015) were supplemented with manual searches of reference lists...

The protective effects of the tuberculosis vaccine Bacillus Calmette-Guerin (BCG) on unrelated infections are thought to be mediated by long-term metabolic changes and chromatin remodeling through histone modifications in innate immune cells such as monocytes, a process termed trained immunity. Here, we show that BCG induction of trained immunity in monocytes is accompanied by a strong increase in glycolysis and, to a lesser extent, glutamine metabolism, both in an in-vitro model and after vaccination of mice and humans...

AIMS: PPARα agonists are in current clinical use as hypolipidaemic agents and show significant antineoplastic effects in human glioblastoma models. To date however, the expression of PPARα in large-scale glioblastoma data sets has not been examined. We aimed to investigate the expression of the transcription factor PPARα in primary glioblastoma, the relationship between PPARα expression and patients' clinicopathological features and other molecular markers associated with gliomagenesis...

BACKGROUND: The aim of the present study was to determine the prevalence of hepatic artery stenosis (HAS) and the prognostic implications of hepatic arterial collaterals in liver transplant (LT) recipients with biliary strictures. METHODS: 105 LT recipients transplanted between 2004 and 2015 at our center had documented biliary strictures. HAS and collaterals were assessed in high quality imaging of the hepatic artery available from 66 recipients. Clinical, demographic and biochemical recipient and donor data were retrospectively analyzed and tested for their association with biliary of arterial complications after LT...

BACKGROUND: Exposure to moldy or damp indoor environments is associated with allergic disease in young children, but it is unclear if the effects persist to adolescence. Our objective was to assess if exposure to mold or dampness during infancy increases the risk of asthma, rhinitis, or IgE sensitization in children followed from birth to 16 years of age. METHODS: We collected questionnaire derived reports of mold or dampness indicators and allergic outcomes from 3798 children in a Swedish birth cohort (BAMSE)...

Vaccination against Hepatitis B Virus (HBV) became mandatory in Italy for all newborns and twelve years-old individuals in the 1991. The immunogenicity of HBV vaccine and the effectiveness of the universal immunization strategy have been widely demonstrated. However the need to assess the antibody concentrations above the well known serological correlate of protection for HBV infection (≥ 10 mIU/mL), established in individuals immunized with a three doses vaccination course, is still recommended in subjects exposed to occupational risks in different settings, particularly the healthcare services...

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen in Cystic Fibrosis (CF), with increasing incidence in recent years. We examined the association between bacterial colonization in the sputum (MRSA with or without pseudomonas (PA)) and computed tomography (CT) scores in CF patients. METHODS: MRSA patients were divided according to PA status based on at least three consecutive sputum cultures; controls were patients without MRSA (with or without PA), matched for gender and age at CT...

Introduction - Idiopathic pulmonary fibrosis (IPF) patients suffer increasing functional limitation with disease worsening disease. Increasing time in sedentary behaviour has been associated with poorer quality of life. Determining thresholds for activity in patients with respiratory disease is difficult due to variable cardiorespiratory limitations between individuals. Measuring sedentary behaviour is not confounded by this limitation and may be a better measurement of activity in patients with respiratory disease...

INTRODUCTION: Treatment of hepatitis C virus (HCV) infection with genotype 3 remains a challenge. The HCV elimination rate with direct acting antivirals (DAAs) is lower than the values reported for other HCV genotypes. In addition, genotype 3 infected patients have a higher risk of disease progression and hepatocellular carcinoma. The aim of this study was to review the relevant literature concerning treatment of HCV genotype 3 patients with interferon-free regimens. MATERIAL AND METHODS: A literature search was conducted in the PubMed/Medline, Embase, and Web of Science electronic databases...

The growing threats to biodiversity and global alteration of habitats and species distributions make it increasingly necessary to consider evolutionary patterns in conservation decision-making. Yet there is no clear-cut guidance on how genetic features can be incorporated into conservation planning processes, with multiple molecular markers and several genetic metrics for each marker type to choose from. Genetic patterns also differ between species, but the potential trade-offs amongst genetic objectives for multiple species in conservation planning are currently understudied...

INTRODUCTION: Two leadless pacemaker (PM) systems were recently developed to avoid pocket- and lead-related complications. As leadless PMs are implanted with a large delivery catheter, cardiac perforation remains a major safety concern. We aimed to provide a literature review on incidence of cardiac perforation with conventional and with leadless PM systems. METHODS AND RESULTS: A systematic review over the last 25 years for studies reporting data on PM lead perforation was performed...

Bisphosphonates are being increasingly used to treat pediatric patients with skeletal disorders. However, the effects of long-term bisphosphonate therapy and cessation of therapy during growth are unclear. Thus, studies were undertaken to determine the effects of alendronate discontinuation following treatment of C57Bl/6 mice during the period of rapid skeletal growth. Compared to vehicle-treated mice, 16 weeks of alendronate treatment starting at 18 days of age resulted in a 3.7 fold increase in trabecular bone in the setting of suppressed bone formation...

Nano-TiO2 is the most widely used form of nanoparticles in commercial industry, and come in two main configurations: rutile and anatase. Rutile TiO2 is used in UV screening applications, while anatase TiO2 crystals have a surface defect that makes them photoreactive. There are numerous reports in the literature of photo-induced toxicity to aquatic organisms following co-exposure to anatase nano-TiO2 and UV. All natural freshwater contains varying amounts of natural organic matter (NOM), which can drive UV attenuation and quench ROS in aquatic ecosystems...

The Principal Response Curve (PRC) method is a constrained ordination method developed specifically for the analysis of community data collected in mesocosm experiments which provides easily understood summaries and graphical representations of community response to stress. PRC is a redundancy analysis (RDA) method and is usually performed on log-transformed abundance data. The choice of a measure of dissimilarity between samples and the choice of the data transformation significantly affect the results of multivariate analysis...

AIMS: A majority of children with Type 1 diabetes in Japan are registered with the government-subsidized Specified Pediatric Chronic Disease Treatment Research Projects (SPCDTRP). In this study, the incidence and prevalence of childhood-onset (< 15 years) Type 1 diabetes in Japan were estimated by drawing on SPCDTRP data. METHODS: Data available for 2005-2012 from the SPCDTRP and Statistics Bureau, Ministry of Internal Affairs and Communications were used to estimate the incidence of Type 1 diabetes for 2005-2010, adjusted to cover those registered within 3 years of disease onset and stratified by sex, age at onset and period of onset...

UV radiation causes two of the most abundant mutagenic and cytotoxic DNA lesions: cyclobutane pyrimidine dimers and 6-4 photoproducts. (6-4) photolyases are light-activated enzymes that selectively bind to DNA and trigger repair of mutagenic 6-4 photoproducts via photoinduced electron transfer from flavin adenine dinucleotide anion (FADH(-) ) to the lesion triggering repair. This review provides an overview of the sequential steps of the repair process, i.e. light absorption and resonance energy transfer, photo-induced electron transfer, and electron-induced splitting mechanisms, with an emphasis on the role of theory and computation...

[(13) C]acetate is known to label metabolites preferentially in astrocytes rather than neurons and it has consequently been used as a marker for astrocytic activity. Recent discoveries suggest that control of acetate metabolism and its contributions to the synthesis of metabolites in brain is not as simple as first thought. Here, using a Guinea pig brain cortical tissue slice model metabolizing [1-(13) C]D-glucose and [1,2-(13) C]acetate, we investigated control of acetate metabolism and the degree to which it reflects astrocytic activity...

Mechanical forces, hypoxia and oxidative stress contribute to skin renewal, perfusion and wound healing, but how are they regulating subcutaneous adipose-derived stem cells (ASCs) in the inflammatory microenvironment associated to skin repair and disorders is unknown. In this study, ASCs were isolated from lipoaspirate samples from plastic surgery patients, primary cultured and their differentiation and secretion of a panel of cytokines with pronounced effects on skin repair and angiogenesis were studied under mechanical stimulation by intermittent fluid flow, 1% hypoxia and oxidative stress by glutathione (GSH) depletion with buthionine sulfoximine (BSO) treatment...
