The timeout procedure in pediatric surgery - effective tool or lip service? A randomized prospective observational study

2020

ABSTRACTBackgroundFor over a decade, the preoperative timeout procedure has been implemented in most pediatric surgery units. In our hospital, a standardized team-timeout is performed before every operation. However, the impact of this intervention has not been systematically studied.PurposeThis study evaluates whether purposefully-introduced errors during the timeout routine are picked up by the operating team members.MethodsAfter ethics board approval and informed consent, deliberate errors were randomly and clandestinely introduced into the timeout routine for elective surgical procedures by a pediatric surgery attending. Errors were randomly selected among wrong name, site, side, allerg…

Dual task cost in balance control and stability in children from 4–7 years old

2019

This study analyzed the development of postural control and the cost of the cognitive task on postural control in the bipedal standing position during childhood. Sixty-six normally developed childr...

Neurally adjusted ventilatory assist: An update

2014

Summary Neurally adjusted ventilatory assist (NAVA) is a new ventilation mode that provides a proportional assistance to the inspiratory effort of the patients. It is based on the use of the diaphragm electromyographic activity (Edi) for the control of the ventilation assistance. The ability of NAVA to improve the limitations of the conventional assisted ventilator modes has been assessed in clinical studies and discussed in this report, as the latest applications of NAVA in children and non-invasive ventilation, due to the improvement of the patient–ventilator interactions delivered by NAVA. We also review the most recent literature on a new trend to use the Edi as a predictor of weaning s…

Visual acuity and contrast sensitivity screening with a new iPad application

2016

We present a new iPad application (app) for a fast assessment of Visual Acuity (VA) and Contrast Sensitivity (CS) whose reliability and agreement was evaluated versus a commercial screening device (Optec 6500). The measurement of VA was programmed in the app in accordance with the Amblyopia Treatment Study protocol. The CS was measured with sinusoidal gratings of four different spatial frequencies: 3, 6, 12 and 18 cpd at the same contrast values of the Functional Acuity Contrast Test (FACT) included in the Optec 6500. Forty-five healthy subjects with monocular corrected visual acuities better than 0.2 logMAR participated in the agreement study. Bland-Altman analyses were performed to assess…

Genetic analyses of the QT interval and its components in over 250K individuals identifies new loci and pathways affecting ventricular depolarization…

2021

AbstractThe QT interval is an electrocardiographic measure representing the sum of ventricular depolarization (QRS duration) and repolarization (JT interval). Abnormalities of the QT interval are associated with potentially fatal ventricular arrhythmia. We conducted genome-wide multi-ancestry analyses in >250,000 individuals and identified 177, 156 and 121 independent loci for QT, JT and QRS, respectively, including a male-specific X-chromosome locus. Using gene-based rare-variant methods, we identified associations with Mendelian disease genes. Enrichments were observed in established pathways for QT and JT, with new genes indicated in insulin-receptor signalling and cardiac energy meta…

REGIONAL DIFFERENCES IN BICEPS FEMORIS FASCICLE LENGTH AND PENNATION ANGLE AFTER A SIMULATED SOCCER MATCH

2017

Background Hamstring Strain Injuries (HSIs) represent 12% of all injuries in soccer players, and their incidence has increased in recent years. Between 53%-84% of HSIs involve the Biceps femoris muscle (BF). Recent studies have shown that soccer players with shorter BF fascicle length (FL) suffer more HSIs and exhibit regional differences in FL and pennation angle (PA) along BF. It is unclear whether there is any regional difference in the degree of change of these parameters after a soccer match. Objective Describe changes in BF muscle architecture after a simulated soccer match. Design Controlled laboratory study. Pre and Post single session. Setting Laboratory. Amateur Level. Participant…

Early cortical processing of vection-inducing visual stimulation as measured by event-related brain potentials (ERP)

2019

Abstract Visual motion stimuli can induce the perception of self-motion in stationary observers (known as vection). In the present study, we investigated the sensory processing underlying vection by measuring the human event-related brain potentials (ERPs) elicited by the movement onset of a visual stimulus. We presented participants a visual stimulus consisting of alternating black-and-white vertical bars that moved in horizontal direction, creating the sensation of vection. The stimulus was presented on a screen that was divided into a central and a surrounding peripheral visual area. Both areas moved independently from each other, resulting in four different movement patterns: the periph…

Rapid Assessment of COVID-19 Screening Program for Travelers in Iran: A Qualitative Study

2022

AbstractObjective:Coronavirus disease 2019 (COVID-19) screening stations set up by Iranian Red Crescent Society have been available for 17 d with the aim of identifying and treating people with coronavirus, reducing road trips, and sensitizing people to the problem. This study aims to investigate the challenges of the procedure.Methods:A qualitative study was used to find the challenges of the COVID-19 screening centers. Volunteers, branch managers, and headquarter managers of the Iranian Red Crescent Society participated in this study applying snowball sampling. Data were collected by means of in-depth semi-structured telephone interviews in April 2020 after completion of the fever screeni…
