Development and validation of the Referee Training Activity Questionnaire (RTAQ): Towards a better understanding of the training practices of soccer officials.

To develop and assess the validity of the , a systematic process was employed: 1) item generation; 2) assessments of content and face validity; and 3) assessments of criterion validity. In stage 1, items were generated following semi-structured interviews with an expert panel (n = 8). Following content analyses, the was developed and comprised 3 primary sections (12 sub-sections) assessing: 1) attributes perceived to underpin soccer officiating performance; 2) general training information; and 3) specific training practices.

A feasibility study with process evaluation of a teacher led resource to improve measures of child health.

Previous school-based interventions have produced positive effects upon measures of children's health and wellbeing but such interventions are often delivered by external experts which result in short-term effects. Thus, upskilling and expanding the resources available to classroom teachers could provide longer-term solutions. This paper presents a feasibility study of an online health resource (Healthy Schools Resource: HSR) developed to assist primary school teachers in the delivery of health-related education.

Coaches Coaching Psychological Skills-Why Not? A Framework and Questionnaire Development.

This study is part of a program of research investigating coaches delivering psychological skills (PS). Here, 3 studies feature an original conceptualization of coaching PS and the development and validation of 2 questionnaires capturing the coaching of PS. The authors conducted a qualitative investigation to establish a conceptual framework that included the fundamental coaching of PS behaviors (CPS-F) and the needs-supportive coaching of PS (CPS-NS).

Prior Knowledge of the Grading Criteria Increases Functional Movement Screen Scores in Youth Soccer Players.

Bryson, A, Arthur, R, and Easton, C. Prior knowledge of the grading criteria increases Functional Movement Screen scores in youth soccer players. J Strength Cond Res 35(3): 762-768, 2021-We sought to determine whether familiarity with the grading criteria of the Functional Movement Screen (FMS) impacted the outcome score in elite youth soccer players.

Interval running with self-selected recovery: Physiology, performance, and perception.

This study (1) compared the physiological responses and performance during a high-intensity interval training (HIIT) session incorporating externally regulated (ER) and self-selected (SS) recovery periods and (2) examined the psychophysiological cues underpinning SS recovery durations. Following an incremental maximal exercise test to determine maximal aerobic speed (MAS), 14 recreationally active males completed 2 HIIT sessions on a non-motorised treadmill. Participants performed 12 × 30 s running intervals at a target intensity of 105% MAS interspersed with 30 s (ER) or SS recovery periods.

The early and mid-term fate of the axillary artery following axillary artery cut-down and cardiac catheterization in infants and young children.

Objectives: To study the early and mid-term vascular complications of axillary artery catheterization in children <2 years by clinical and ultrasound examination.

Background: Femoral arterial access for cardiac catheterization in young children is associated with significant morbidity. Early complications of axillary artery catheterization have been reported but no long-term vascular follow-up data are available.

Sedaghatian spondylometaphyseal dysplasia with pachygyria and absence of the corpus callosum.

We report on a female infant with a metaphyseal dysplasia and a neuronal migration abnormality consistent with a diagnosis of Sedaghatian spondylometaphyseal dysplasia. This child, born to nonconsanguineous Caucasian parents, was hypotonic from birth and experienced recurrent cyanotic episodes within a few hours of delivery. Cerebral imaging revealed absence of the corpus callosum and marked frontotemporal pachygyria.

Magnetic resonance imaging in preterm infants.

MR imaging of the premature infant poses a number of challenges with regard to safety, sequence optimization and recognition of the normal appearances of the developing brain. In this paper we discuss these challenges, and review the common intracerebral abnormalities associated with premature birth. Although the outcome for very-low-birth-weight babies has improved over the last decade, there remains a significant risk of subsequent development of neurological disability.

Posterior fossa abnormalities seen on magnetic resonance brain imaging in a cohort of newborn infants.

Objective: To describe the nature and frequency of posterior fossa (PF) lesions in infants who underwent magnetic resonance (MR) brain imaging in the neonatal period and to correlate with cranial ultrasound (CUS) findings and clinical outcome.

Study Design: A retrospective review of all neonatal MR brain imaging from 1996 to 2001 (n=558). MR images, CUS and case notes were reviewed in infants with PF abnormality.

Ultrasonography in the diagnosis and management of developmental hip dysplasia (UK Hip Trial): clinical and economic results of a multicentre randomised controlled trial.

Background: Clinical screening aims to identify and treat neonatal hip instability associated with increased risk of hip displacement, but risks failures of diagnosis and treatment (abduction splinting), iatrogenic effects, and costs to parents and health services. Our objectives were to assess clinical effectiveness and net cost of ultrasonography compared with clinical assessment alone, to provide guidance for management of infants with clinical hip instability.

Methods: Infants with clinical hip instability were recruited from 33 centres in UK and Ireland and randomised to either ultrasonographic hip examination (n=314) or clinical assessment alone (n=315).
