The Ames room and the misunderstood versions and depictions.

The Ames room illusion is one of the best-known geometrical illusions but its geometrical properties are often misunderstood. This study discusses the differences in the geometrical properties between the original Ames room and what have been often referred to as "Ames rooms" in recent studies.

Model-Informed Support of Dose Selection for Prophylactic Treatment with Dalcinonacog Alfa in Adult and Paediatric Hemophilia B Patients.

Introduction: Dalcinonacog alfa (DalcA), a novel subcutaneously administered recombinant human factor IX (FIX) variant is being developed for adult and paediatric patients with hemophilia B (HB). DalcA has been shown to raise FIX to clinically meaningful levels in adults with HB. This work aimed to support dosing regimen selection in adults and perform first-in-paediatric dose extrapolations using a model-based pharmacokinetic (PK) approach.

Learning under social versus nonsocial uncertainty: A meta-analytic approach.

Much of the uncertainty that clouds our understanding of the world springs from the covert values and intentions held by other people. Thus, it is plausible that specialized mechanisms that compute learning signals under uncertainty of exclusively social origin operate in the brain. To test this hypothesis, we scoured academic databases for neuroimaging studies involving learning under uncertainty, and performed a meta-analysis of brain activation maps that compared learning in the face of social versus nonsocial uncertainty.

Comparing saccadic and manual responses in the attention network test.

Attention is proposed to be a system of multiple functional networks, including alertness, orienting and executive control. A popular experimental paradigm for testing these networks and their interactions within a single design is the Attentional Networks Test (ANT) (Fan et al., 2002).

Pamrevlumab, an anti-connective tissue growth factor therapy, for idiopathic pulmonary fibrosis (PRAISE): a phase 2, randomised, double-blind, placebo-controlled trial.

Background: Connective tissue growth factor (CTGF) is a secreted glycoprotein that has a central role in the process of fibrosis. This study was designed to assess the safety, tolerability, and efficacy of pamrevlumab (FG-3019), a fully recombinant human monoclonal antibody against CTGF, in idiopathic pulmonary fibrosis. The aim was to establish whether pamrevlumab could slow, stop, or reverse progression of idiopathic pulmonary fibrosis.

Quantitative CT analysis using functional imaging is superior in describing disease progression in idiopathic pulmonary fibrosis compared to forced vital capacity.

Background: Idiopathic pulmonary fibrosis (IPF) is chronic fibrosing pneumonia with an unpredictable natural disease history. Functional respiratory imaging (FRI) has potential to better characterize this disease. The aim of this study was to identify FRI parameters, which predict FVC decline in patients with IPF.

Migrant Women's Economic Success in Russia: Objective Reality and Subjective Assessment.

This study contributes to the growing body of literature on the outcomes of labor migration by focusing on the effects of migrant legal status on the economic and perceptual measures of migration success. To study the effects of legal status, we use a sample of Central Asian migrant women who work in Russia and of their native counterparts who occupy the same positions on the labor market. Similar to the studies in the developed settings, we find that a temporary legal status is associated with an earnings penalty and that permanent legal status corrects this earning disparity.

[The effect of biguanide derivatives on oxidative stress in rats with hyperglycemia].

The effect of the synthetic biguanide derivatives N-[imino(1-piperidinyl)methyl]guanidine (NIPMG) and 1,3-dimethyl-5-[(carbamimidamidomethanimidoil) amino]benzoyl-1,3dicarboxylate (DCB) on the degree of proteins oxidative modification (POM) and the DNA fragmentation, the content of the lipid peroxidation primary products - conjugated dienes (CD), and the activity of glutathione antioxidant system in the liver and heart of rats with experimental hyperglycemia was investigated. Administration of the biguanides (15.0 mg/kg) to hypoglycemic rats promoted reduction of the free radical processes intensity in the studied tissues.

Economic Swings, Political Instability and Migration in Kyrgyzstan.

Individual-level migration responses to economic fluctuations and political instability remain poorly understood. Using nationally representative survey data from Kyrgyzstan, we look at variations in levels and propensities of internal and temporary international migration and relate them to changes in the economic and political environment in that Central Asian nation in the first decade of the century. A multinomial event history model predicting yearly risks of both types of migration detects no clear association of internal migration risks with episodes of heightened political instability but shows a decrease in those risks in response to the strongest economic shock of the observation period.

Efficacy of pirfenidone in patients with idiopathic pulmonary fibrosis with more preserved lung function.

This post hoc analysis examined the differences in idiopathic pulmonary fibrosis disease progression and the effects of pirfenidone in patients stratified by more preserved versus less preserved baseline lung function status using forced vital capacity (FVC) or GAP (gender, age and physiology) index stage.Efficacy outcomes, i.e.

An Open-label, Phase II Study of the Safety and Tolerability of Pirfenidone in Patients with Scleroderma-associated Interstitial Lung Disease: the LOTUSS Trial.

Objective: Systemic sclerosis-associated interstitial lung disease (SSc-ILD) shares a number of clinical features and pathogenic mechanisms with idiopathic pulmonary fibrosis (IPF). This study was designed to evaluate the tolerability of the IPF treatment pirfenidone in SSc-ILD. The known gastrointestinal, skin, and liver adverse events (AE) of pirfenidone are of importance given the involvement of these organs in SSc.

A phase 3 trial of pirfenidone in patients with idiopathic pulmonary fibrosis.

Background: In two of three phase 3 trials, pirfenidone, an oral antifibrotic therapy, reduced disease progression, as measured by the decline in forced vital capacity (FVC) or vital capacity, in patients with idiopathic pulmonary fibrosis; in the third trial, this end point was not achieved. We sought to confirm the beneficial effect of pirfenidone on disease progression in such patients.

Methods: In this phase 3 study, we randomly assigned 555 patients with idiopathic pulmonary fibrosis to receive either oral pirfenidone (2403 mg per day) or placebo for 52 weeks.

Psychometric evaluation of a patient-reported symptom assessment tool for adults with haemophilia (the HAEMO-SYM).

In patients with haemophilia, repeated bleeding events result in significant comorbid conditions that can degrade health-related quality of life. Clinician-reported symptom measures are available for use in patients with haemophilia A or B; however, there has not been a validated patient-reported symptom evaluation instrument available for haemophilia to date. The objective of this study was to develop and evaluate a self-report instrument, the HAEMO-SYM, for measuring symptom severity in patients with haemophilia.

Stability, efficacy, and safety of continuously infused sucrose-formulated recombinant factor VIII (rFVIII-FS) during surgery in patients with severe haemophilia.

Bolus injection (BI) of sucrose-formulated recombinant factor VIII (rFVIII-FS) is an approved treatment for haemophilia patients undergoing major surgery. Continuous infusion (CI) during surgery has potential benefits by providing steady administration of replacement factor to the patient, avoiding high peaks and low troughs. We tested the stability of rFVIII-FS under CI conditions and conducted a single-centre, open-label, phase III study to evaluate the efficacy and safety of CI using rFVIII-FS in haemophilia A patients undergoing surgery.

Cross-cultural development and psychometric evaluation of a patient-reported health-related quality of life questionnaire for adults with haemophilia.

Co-morbidities of haemophilia, such as arthropathy and blood-borne infections, can adversely affect the quality of life of adult patients with haemophilia. The purpose of this study was to develop and validate a haemophilia-specific health-related quality of life questionnaire for adults (HAEMO-QoL-A). Subjects with varying severities of haemophilia completed the HAEMO-QoL-A at baseline and 4 weeks.

Safety and efficacy of sucrose-formulated full-length recombinant factor VIII: experience in the standard clinical setting.

The safety of full-length sucrose-formulated recombinant factor VIII (rFVIII-FS; Kogenate FS) for up to 24 months of use was evaluated in a postmarketing observational study in Europe. Long-term safety and efficacy data were available for 212 patients with severe haemophilia A, including 13 previously untreated patients (PUPs) and 12 patients with 1-19 exposure days (EDs). Patients accumulated a mean (+/- SD) of 187 (121) EDs to rFVIII-FS and received a total of 39,627 infusions, mainly for prophylaxis and for the treatment of 4,283 spontaneous or trauma-related bleeds during an average observation time of 710 (136) days.
