BACKGROUND: Rodent operant tests that include premature responses (PR) as a measure of impulsivity commonly use variable intertrial interval (vITI) schedules. The rodent continuous performance test (rCPT) is suitable for a vITI schedule. NEW METHOD: We optimised the analysis for a rCPT vITI schedule with intertrial intervals (ITIs) of 3, 6, and 12s. Examining the nature of first (FiT) and following touches (FoT) to the blank screen led to a separate quantification of these two behaviours into the first touches level (%FiT) and the following-to-first touches ratio (FoT/FiT)...

BACKGROUND: In this work, we developed many machine learning classifiers to assist in diagnosing respiratory changes associated with sarcoidosis, based on results from the Forced Oscillation Technique (FOT), a non-invasive method used to assess pulmonary mechanics. In addition to accurate results, there is a particular interest in their interpretability and explainability, so we used Genetic Programming since the classification is made with intelligible expressions and we also evaluate the feature importance in different experiments to find the more discriminative features...

Impulse oscillometry (IOS) is a method for measuring respiratory impedance based on the forced oscillation technique (FOT). The IOS measurement requires only quiet tidal breathing, which is simple, suitable for a wide range of people and provides various respiratory physiological parameters. For promoting the standardization and clinical application of IOS measurement in China, based on the relevant research evidence and the updated technical standards by European Respiratory Society, this article provided a brief introduction to the background of IOS technique and the current situation of its clinical application in China, as well as the recommendations and interpretations on the indications and contraindications, device calibration, testing protocols, quality control requirements including acceptability and repeatability criteria, measurement parameters and graphs, testing results interpretation, references values and normal limits, report template, clinical application including assessment of airway patency, airway reversibility and responsiveness, small airway function and so on...

INTRODUCTION: The goal of the present study is to assess the relationship between functional respiratory parameters measured by the forced oscillation technique (FOT) in COPD patients and (1) dyspnea; (2) inspiratory capacity (IC), along with the variations occurring subsequent to bronchodilation. METHODS: This cross-sectional study analyzed 40 stable COPD patients. Dyspnea was assessed by means of the San Diego Shortness of Breath Questionnaire. Forced oscillations were measured before and after bronchodilation by means of routine pulmonary function tests (PFTs)...

This paper deals with predicting the effective thermal conductivity (ETC) of injection-moulded short fibre reinforced polymers (SFRPs) using two different homogenisation schemes: a scheme based on the dielectric theory for pseudo-oriented inclusions and a two-step homogenisation model based on the mean-field homogenisation approach. In both cases, the fibre orientation tensor (FOT) obtained from Autodesk Moldflow® simulation was used. The Moldflow FOT predictions were validated via structure tensor analysis of micro-computed X-ray tomography (micro-CT) scans of the part...

The forced oscillation technique (FOT) is a non-volitional assessment that is used during tidal breathing. A variant of FOT uses a pseudorandom noise (PRN) signal which we postulated might have utility in assessing lung function in prematurely born children. We, therefore, undertook a systematic review to evaluate the evidence regarding PRN FOT. A comprehensive search of the literature was conducted by using the following databases: Medline, Embase, Web of Science and CINAHL. Observational studies, case series/reports and randomized-controlled trials were eligible for inclusion...

Our aim is to estimate the number of procedures needed for one to perform RIRS consistently. MATERIAL AND METHODS: a urology resident had his first 80 RIRS for nephrolithiasis analyzed quantitatively and qualitatively. The procedures were divided into 4 groups containing 20 surgeries each (I to IV), according to their order, for comparison...

OBJECTIVE: To identify short-term repeatability of forced oscillation technique (FOT) measurement of lung function, assess the lung function response to bronchodilators (BD) by FOT, prove the concept that only some very preterm infants manifest a change in lung mechanics in response to BD. STUDY DESIGN: We retrospectively analysed respiratory system resistance (Rrs) and reactance (Xrs) measured by FOT (Fabian HFOi, Vyaire). The measurement short-term repeatability was assessed in 43 patients on 60 occasions; BD responsiveness was assessed using a different dataset, including 38 measurements in 18 infants...

Forced oscillation technique (FOT) provides unique information on respiratory system mechanical properties complementing pulmonary function testing. However, a lack of evidence guiding acquisition/reporting of parameters has slowed clinical FOT adoption. Current European Respiratory Society (ERS) standards recommend 3-5 trials per session comprising three trials with a coefficient of variation (CoV) ≤ 10% for low-frequency resistance. We present an analysis of different combinations of trial selection methods and session validity thresholding variables (low- and mid-frequency resistance and reactance [R5, R19, X5], low-frequency reactance area [AX] and tidal volume) comparing proportion of subjects achieving valid data across two test sessions (7 ± 3 days apart) and within and between session measurement variabilities...
