Validity and internal consistency of the thoracic outlet syndrome index for patients with thoracic outlet syndrome
Background: No validated scales exist specifically for measuring quality of life (QoL) and functioning level in patients with thoracic outlet syndrome (TOS). This cross-sectional survey examined whether some items adopted from validated QoL scales could be suitable for patients with TOS.Methods: To find an optimal thoracic outlet syndrome index (TOSI), a panel of 14 specialists experienced in treating TOS independently evaluated the relevance of 19 items adopted from scales used in other upper-extremity syndromes. After undergoing surgery for TOS, 52 patients rated the relevance of those items found by experts to be relevant. Content validity was measured by a content validity index, content validity ratio, and modified κ. The internal consistency of 15 retained items was assessed with the Cronbach α, and its construct validity was assessed by an exploratory factor analysis.Results: Of the 19 items, 15 were considered relevant for TOS by the panelists, with an overall test content validity index of 0.93. The internal consistency of these 15 items was excellent. The exploratory factor analysis accompanied by a parallel analysis confirmed the uni-dimensionality of the TOSI. All 15 items that the panelists considered relevant were also items that the patients marked with scores over 7 points on an 11-point scale of relevance.Conclusion: The internally consistent, face- and content-valid TOSI scale is proposed for use in evaluating specifically the QoL in TOS patients, as well as improving future longitudinal studies comparing functioning before and after interventions or spontaneous recovery in TOS patients.</p
Comprehensive evaluation of coding region point mutations in microsatellite-unstable colorectal cancer
Microsatellite instability (MSI) leads to accumulation of an excessive number of mutations in the genome, mostly small insertions and deletions. MSI colorectal cancers (CRCs), however, also contain more point mutations than microsatellite-stable (MSS) tumors, yet they have not been as comprehensively studied. To identify candidate driver genes affected by point mutations in MSI CRC, we ranked genes based on mutation significance while correcting for replication timing and gene expression utilizing an algorithm, MutSigCV. Somatic point mutation data from the exome kit-targeted area from 24 exome-sequenced sporadic MSI CRCs and respective normals, and 12 whole-genome-sequenced sporadic MSI CRCs and respective normals were utilized. The top 73 genes were validated in 93 additional MSI CRCs. The MutSigCV ranking identified several well-established MSI CRC driver genes and provided additional evidence for previously proposed CRC candidate genes as well as shortlisted genes that have to our knowledge not been linked to CRC before. Two genes, SMARCB1 and STK38L, were also functionally scrutinized, providing evidence of a tumorigenic role, for SMARCB1 mutations in particular. © 2018 The Authors.

Hein FondsFunder: Scott Family Junior Research FellowshipAbstract: Autism is frequently associated with difficulties with top-down attentional control, which impact on individuals’ mental health and quality of life. The developmental processes involved in these attentional difficulties are not well understood. Using a data-driven approach, 2 samples (N = 294 and 412) of infants at elevated and typical likelihood of autism were grouped according to profiles of parent report of attention at 10, 15 and 25 months. In contrast to the normative profile of increases in attentional control scores between infancy and toddlerhood, a minority (7–9%) showed plateauing attentional control scores between 10 and 25 months. Consistent with pre-registered hypotheses, plateaued growth of attentional control was associated with elevated autism and ADHD traits, and lower adaptive functioning at age 3 years

A multiplexed FBG based sensor platform for flow and temperature measurements in the Baltic Sea
In this paper a multiplexed multi-parameter marinized sensory array is described. This was deployed on the continental slope off the Keri Island marine observatory in the Gulf of Finland (Estonia). The sensor array is made up of 4 measurement stations which are connected in series. Across these measurement stations, a total of 16 temperature sensors, 4 attitude sensors (each consisting of 3 individual fiber sensors) and 16 flow sensors were successfully deployed. They were addressed over 1.1 km via 20 single-mode (SMF-28e) optical fibers contained in a single marine compliant ruggedized umbilical. The bio-inspired fiber optic flow sensors are designed to mimic the behavior of the superficial neuromasts naturally found as part of the lateral line sensory organ present in fish. The sensor is composed of optical fibers inscribed with Fiber Bragg Gratings glued together in a polymer matrix which are then encapsulated in a polyurethane shell. The sensors response has been tested in DC flows in a tow tank and have demonstrated the ability of measuring flow speed from 0.05 ms-1 to 2.5 ms-1. The main aim of the deployment was to demonstrate the capabilities of fiber sensor technology for long-term oceanographic applications. The measurement period described lasted over two months and the sensor system performed well in comparison with data was gathered from commercial instrumentation available.</p
Epidemiology of Overuse Injuries among High-School Athletes in the United States
To examine high school overuse injury rates and patterns by sex and sport.
High school athletes participating in the High School Reporting Information Online study were examined in a descriptive epidemiologic study. Overuse injury data for the 2006/2007-2011/2012 academic years collected via High School Reporting Information Online from a large national sample of US high schools where certified athletic trainers completed detailed injury reports were evaluated.
From 2006/2007 to 2011/2012, a total of 2834 overuse injuries were reported during 18 889 141 athletic exposures (1.50 per 10 000 athletic exposures). Girls had greater rates of overuse injury (1.88) than boys (1.26) (rate ratio 1.50, 95% CI 1.39-1.61). The greatest rates were in girls' track and field (3.82) and girls' field hockey (2.93). Overuse injuries represented 7.7% of all injuries, ranging from a low of 1.4% of all boys' ice hockey injuries to a high of 55.7% of all boys' swimming and diving injuries. Overall, overuse injuries were evenly distributed across athletes in each year of high school (freshman, 25.6%; sophomore, 25.3%; junior, 24.9%; senior, 24.3%). However, there were distinct differences by sex. The most frequent site of injury was the lower leg (21.8%). Injuries most frequently resulted in time loss of less than 1 week (50.0%), with only 7.6% resulting in time loss greater than 3 weeks.
Overuse injury patterns differed by sex and sport. A better understanding of overuse injury patterns and criteria for return to play may help direct preventative measures and injury management
