Safety and Activity of the First-in-Class Sym004 Anti-EGFR Antibody Mixture in Patients with Refractory Colorectal Cancer

2015

Abstract Tumor growth in the context of EGFR inhibitor resistance may remain EGFR-dependent and is mediated by mechanisms including compensatory ligand upregulation and de novo gene alterations. Sym004 is a two-antibody mixture targeting nonoverlapping EGFR epitopes. In preclinical models, Sym004 causes significant EGFR internalization and degradation, which translates into superior growth inhibition in the presence of ligands. In this phase I trial, we observed grade 3 skin toxicity and hypomagnesemia as mechanism-based dose-limiting events during dose escalation. In dose-expansion cohorts of 9 and 12 mg/kg of Sym004 weekly, patients with metastatic colorectal cancer and acquired EGFR inhi…

Strength of memory encoding affects physiological responses in the Guilty Actions Test

2009

The Guilty Actions Test (GAT) is a valid and scientifically sound technique of forensic psychophysiology that allows for the detection of concealed memories. However, its application has been challenged because the results might be affected by the culprit's forgetting of crime details as well as the leakage of information to innocents. In the current study, these aspects were examined by varying the amount of time between a mock crime and the subsequent GAT, as well as by contrasting culprits with informed innocents. It turned out that culprits specifically forgot peripheral crime details during a period of 2 weeks whereas informed innocents showed similar forgetting for all details. As a c…

Increased amygdala and parahippocampal gyrus activation in schizophrenic patients with auditory hallucinations: An fMRI study using independent compo…

2010

Objective: Hallucinations in patients with schizophrenia have strong emotional connotations. Functional neuroimaging techniques have been widely used to study brain activity in patients with schizophrenia with hallucinations or emotional impairments. However, few of these Studies have investigated the association between hallucinations and emotional dysfunctions using an emotional auditory paradigm. Independent component analysis (ICA) is an analysis method that is especially useful for decomposing activation during complex cognitive tasks in which multiple operations occur simultaneously. Our aim in this Study is to analyze brain activation after the presentation of emotional auditory stim…

The Added Value of Studying Embodied Responses in Couple Therapy Research: A Case Study.

2018

This article reports on the added value of embodied responses identified through sympathetic nervous system (SNS) activity in couple therapy research. It focuses on moments of change and the timing of therapeutic interventions or therapeutic moves in a couple therapy session. The data for this single-case study comprise couple therapy process videotapes recorded in a multi-camera setting, and measurements of participants' SNS activity. The voluntary participants were a marital couple in their late thirties and two middle-aged male psychotherapists. The division into topic segments showed how the key issue of seeking help, which was found to comprise three separate components, was repeatedly…

Comparing asthma treatment in elderly versus younger patients

2011

SummaryA randomised 6-month study compared two maintenance doses of budesonide/formoterol (Symbicort® Turbuhaler®)hhNeither the Symbicort SMART posology nor the dry powder formulation, Turbuhaler, is currently approved in the US. maintenance and reliever therapy (Symbicort SMART®), 160/4.5 μg 1 × 2 and 2 × 2, in 8053 asthmatics with symptoms despite treatment with inhaled corticosteroids ± inhaled long-acting β2-agonists. This analysis compared response to the two treatments in elderly patients, ≥65 years, with that in younger patients. Elderly patients with early- or late-onset asthma were also compared.Elderly patients had lower post-bronchodilator FEV1 percentage predicted normal at base…

Adjustable maintenance dosing with budesonide/formoterol in a single inhaler provides effective asthma symptom control at a lower dose than fixed mai…

2004

Asthma guidelines suggest a stepwise approach to maintenance pharmacological treatment of persistent asthma until control is attained, and a 3 month review of the fixed maintenance dosing for step-up or step-down adjustment. This 12-week study compared the efficacy and safety of budesonide/formoterol in a single inhaler (Symbicort Turbuhaler 160/4.5 or 80/4.5 microg) given as adjustable maintenance or fixed maintenance dosing. Patients (n = 2358) were randomised to budesonide/formoterol fixed maintenance dosing (two inhalations bid) or adjustable maintenance dosing (two inhalation bid; stepping up to four inhalations bid if asthma worsened for a maximum of 14 days; stepping down to two inha…

Tiotropium Respimat® in asthma: a double-blind, randomised, dose-ranging study in adult patients with moderate asthma

2013

Tiotropium, a once-daily long-acting anticholinergic bronchodilator, when administered via Respimat® SoftMist™ inhaler (tiotropium Respimat®) significantly reduces the risk of severe exacerbations and improves lung function in patients with severe persistent asthma that is not fully controlled despite using inhaled corticosteroids (ICS) and long-acting β2-agonists. To further explore the dose–response curve in asthma, we investigated the efficacy and safety of three different doses of tiotropium Respimat® as add-on to ICS in symptomatic patients with moderate persistent asthma. In this randomised, double-blind, placebo-controlled, four-way crossover study, patients were randomised to tiotro…

The effect of challenge method on methacholine-induced changes in sensitivity and air trapping

2010

Summary Background The methacholine challenge test performed with the tidal breathing method induces a greater fall in FEV 1 than the dosimeter method; however, the effect of the challenge method on methacholine-induced fall in FVC has not been investigated. Objective To determine the influence of the challenge method on methacholine-induced changes in FEV 1 and FVC. Methods Airway responsiveness to methacholine was determined by dosimeter method and tidal breathing method in 37 subjects with suspected asthma. The dosimeter was modified to deliver an identical volume to that obtained with the tidal breathing method and the same nebulizer model was used for the two challenges. The response w…

Cardiac surgery outcomes in patients with coronavirus disease 2019 (COVID-19): A case-series report

2020

Abstract Objective The impact of coronavirus disease 2019 (COVID-19) on the postoperative course of patients after cardiac surgery is unknown. We experienced a major severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak in our cardiac surgery unit, with several patients who tested positive early after surgery. Here we describe the characteristics, postoperative course, and laboratory findings of these patients, along with the fate of the health care workers. We also discuss how we reorganize and reallocate hospital resources to resume the surgical activity without further positive patients. Methods After diagnosis of the first symptomatic patient, surgery was suspended. Naso…

Dose-Related Effect of Beclomethasone Dipropionate on Airway Responsiveness in Asthma

1990

The effects of twice daily inhaled beclomethasone dipropionate (BDP) at two dose levels (500 and 1,000 micrograms daily) on the airway responsiveness to inhaled histamine was evaluated by a randomized, single-blind, cross-over study in 10 patients with stable asthma. The 12-week study began with a 3-week run-in period of baseline treatment, which was continued unchanged throughout the study, and the two treatment periods were separated by a 3-week placebo period. Patients attended the laboratory every 3 weeks for spirometry and histamine inhalation tests to determine the provocative concentration of histamine causing a 20% fall in forced expiratory volume in 1 s (PC20 of FEV1). There was a …
