Enhanced Efficiency of a Novel Porous Tip Irrigated RF Ablation CatheterIntroductionIrrigated tip radiofrequency (RF) catheter ablation is the most frequently used technology for pulmonary vein isolation (PVI). The purpose of this study was to compare the efficiency and the safety of 2 different open irrigated tip RF ablation catheters.Methods and ResultsA total of 160 patients with symptomatic AF (29% persistent, 68% male, 61 ± 10 years) were randomized to circumferential PVI using 2 different irrigated tip catheters: (1) the novel Thermocool SF® with a porous tip (56 holes) or (2) the Thermocool® catheter with 6 irrigation holes at the distal tip in both power‐ and temperature‐controlled modes.PVI procedural time and RF duration were significantly shorter with SF® versus Thermocool® catheter: 104.5 versus 114 minutes (P = 0.023) and 35.4 minutes versus 39.9 minutes (P < 0.001), respectively. Similarly, the total fluoroscopy time and dose were shorter with SF® versus. Thermocool® catheter: 21 minutes versus 24 minutes (P = 0.02) and 1014.5 μGy*m2 versus 1377 μGy*m2 (P < 0.0001), respectively. Irrigation volume was lower with SF®: 600 mL versus 1100 mL, (P < 0.0001) and the rates of complications were not significantly different (0.6% vs 0.49%, P = 0.66). At 20.5 ± 7.5 months follow‐up, there were no significant differences with regard to arrhythmia freedom between SF® (59.2%) and TC® groups (59.3%), (P = 0.61).ConclusionsUsing the novel irrigated tip SF catheter, PVI is achieved within a shorter ablation and procedural durations. The underlying mechanisms and potential differences in RF lesion size remain to be elucidated.

SummaryAcquiring a whole mouse brain at the micrometer scale is a complex, continuous and time‐consuming process. Because of defects caused by sample preparation and microscopy, the acquired image data sets suffer from various macroscopic density artefacts that worsen the image quality. We have to develop the available preprocessing methods to improve image quality by removing the artefacts that effect cell segmentation, vascular tracing and visualization. In this study, a set of automatic artefact removal methods is proposed for images obtained by tissue staining and optical microscopy. These methods significantly improve the complicated images that contain various structures, including cells and blood vessels. The whole mouse brain data set with Nissl staining was tested, and the intensity of the processed images was uniformly distributed throughout different brain areas. Furthermore, the processed image data set with its uniform brightness and high quality is now a fundamental atlas for image analysis, including cell segmentation, vascular tracing and visualization.

Published: June 2013

This study examined the moderating role of polychronicity, the preference for multitasking, on the relationship between multitasking ability and performance. The results support the importance of fit in understanding the interaction between preference for and ability to multitask. The relationship between multitasking ability and an overall performance composite was stronger for individuals higher in polychronicity. For employees low in polychronicity, having the ability to multitask did not translate into meaningful performance differences.Practitioner points

Overall job performance is optimal for employees with both the ability to multitask and the preference for doing so.

The relationship between multitasking ability and overall job performance is negligible for monochronic employees.

ABSTRACTBACKGROUNDSchool‐based interventions hold promise for child obesity prevention. Implemented as a part of the Winning With Wellness obesity prevention project, the “Go Slow Whoa” meal pattern (GSW) was designed to promote healthier foods in school cafeterias. This investigation determined perceived program effectiveness and impact on student's food purchases.METHODSA mixed method design was used, including focus groups with cafeteria staff (CS), quantitative analysis of CS and teacher surveys, and pre‐post analysis of cafeteria sales. A total of 37 CS and 131 teachers from 7 schools in northeast Tennessee participated.RESULTSCS recognized the important role of school nutrition services in influencing student choices, yet perceived lack of administrative support for cafeteria‐based interventions and minimal interaction with teachers were barriers. CS also believed that students choose less nutritious options due to family influence. Cafeteria sales indicated that changes were made in menu planning and production, yet students' choices improved minimally. Teachers expressed moderate levels of confidence in GSW as influential in children's dietary habits.CONCLUSIONSSuccessful implementation of school‐based nutrition programs requires supportive policies, administrators, and teachers. CS should be included in program implementation efforts and the role of school nutrition services should be maximized.
Game‐Based Learning as a Vehicle to Teach First Aid Content: A Randomized Experiment
Authors: Charlier Nathalie , De Fraine Bieke 
Published: June 2013

ABSTRACTBACKGROUNDKnowledge of first aid (FA), which constitutes lifesaving treatments for injuries or illnesses, is important for every individual. In this study, we have set up a group‐randomized controlled trial to assess the effectiveness of a board game for learning FA.METHODSFour class groups (120 students) were randomly assigned to 2 conditions, a board game or a traditional lecture method (control condition). The effect of the learning environment on students' achievement was examined through a paper‐and‐pencil test of FA knowledge. Two months after the intervention, the participants took a retention test and completed a questionnaire assessing enjoyment, interest, and motivation.RESULTSAn analysis of pre‐ and post‐test knowledge scores showed that both conditions produced significant increases in knowledge. The lecture was significantly more effective in increasing knowledge, as compared to the board game. Participants indicated that they liked the game condition more than their fellow participants in the traditional lecture condition.CONCLUSIONThese results suggest that traditional lectures are more effective in increasing student knowledge, whereas educational games are more effective for student enjoyment. From this case study we recommend alteration or a combination of these teaching methods to make learning both effective and enjoyable.
Comparison of the pharyngeal pressure provided by two heated, humidified high‐flow nasal cannulae devices in premature infants
Authors: Collins Clare L , Holberton James R , König Kai 
Published: June 2013

AimsThis study aims to determine if there is a difference in the pharyngeal pressure, measured as a surrogate for continuous positive distending airway pressure, delivered to premature infants between two commonly used heated, humidified high‐flow nasal cannulae (HHHFNC) devices: Fisher & Paykel Healthcare HHHFNC and Vapotherm 2000i.MethodsPharyngeal pressure measurements were taken from stable premature infants receiving HHHFNC for respiratory support. Flow rates of 2–8 L/min were studied.ResultsNine infants had pharyngeal pressure measurements recorded with both HHHFNC devices at flow rates of 2–8 L/min. There was no difference in pharyngeal pressures recorded between devices at flow rates of 2–6 L/min; measured pressure was linearly associated with flow (R2 = 0.9). At flow rates of 7 L/min, Vapotherm delivered a mean (standard deviation) pharyngeal pressure of 4.7 (2.2) cmH2O compared with 4.23 (2.2) cmH2O by the Fisher & Paykel device (P = 0.04). At a flow of 8 L/min, the mean pharyngeal pressure via Vapotherm was 4.9 (2.2) cmH2O compared with 4.1 (2.3) cmH2O with the Fisher & Paykel device (P = 0.05).ConclusionsBoth HHHFNC delivered similar pharyngeal pressures at flow rates of 2–6 L/min. The pressure limiter valve of the Fisher & Paykel device attenuated the pharyngeal pressures at flows of 7 and 8 L/min. Vapotherm trended towards higher delivered pharyngeal pressure at flow rates 7 and 8 L/min, but the clinical significance of the difference remains unclear.

Published: June 2013

AimsThe study aims to explore the effect of participation in adapted cycling on quality of life for children with cerebral palsy (CP).MethodsThe study used a qualitative approach developing creative mosaic methods using interviews and diaries. This study had two groups of children with CP: those who participated in adapted cycling and a control group who had not yet started. Children with CP aged 2–17 years who were already cycling were invited to take part in two interviews at the beginning and end of a 6‐week period and keep a cycling diary during this time. The control group of children with CP aged 2–17 years were asked to keep a diary of physical activities over 6 weeks and to take part in one interview at the end. Welsh, English, Bengali and Arabic were the languages spoken, and some children used communication aids.ResultsResults presented here include the first 25 children's interviews and diaries. The emergent themes from the analysis are: learning a new skill, the impact on wider family and friends, social participation and future aspirations. The diaries added an emotional dimension, by illustrations drawn by the children.ConclusionThe children who took part in adapted cycling enjoyed this experience and it improved their sense of well‐being. Some in the control group went on to participate in adapted cycling. Physiotherapists can carry out creative research to hear the voices of children and young people with CP and incorporate their views and ideas into the development of service model delivery and treatment programmes.

Published: June 2013

AimsPerfluorocarbon administration increases cerebral blood flow. This can be mitigated by preventing a rise in carbon dioxide by adjusting pressure‐controlled ventilation. Volume‐controlled ventilation should prevent increases in arterial carbon dioxide and cerebral blood flow. This study aims to determine if cerebral blood flow is increased during administration of 10 mL/kg of perfluorocarbon while using volume‐controlled ventilation.MethodsTwo New Zealand white rabbits, ventilated with volume‐control, were each allocated to six dosing events where each dosing event was randomly allocated to one of two dosing strategies: a control group – given a sham dose of air (10 mL/kg) over 20 min; or a partial liquid ventilation group – given 10 mL/kg FC‐77 slowly over 20 min. Data were recorded for 1 min before and 30 min after the start of each dosing event. No adjustment of ventilation (except fraction of inspired oxygen) was allowed during each dosing event.ResultsThere were no significant changes over time and no differences between groups for carotid blood flow (P = 0.48 at the end of the dose). There were slight increases in cortical cerebral blood flow in both groups; there was no statistically significant difference between groups (P = 0.56 at end dose and P = 0.49 at time of maximum difference). There was no difference between groups for the variability in carotid blood flow or cortical cerebral blood flow.ConclusionsCerebral blood flow was not significantly increased during administration of a dose of 10 mL/kg of perfluorocarbon during commencement of partial liquid ventilation when using volume‐controlled ventilation.

Published: June 2013

AimThe following paper describes the Autism Spectrum Assessment Clinic which operates at Melton Health, a publically funded health service in Melbourne's west.MethodsA retrospective audit of 234 children assessed between 2007 and 2012 in the Autism Spectrum Assessment Clinic was undertaken. Characteristics of the children assessed (age, sex, locality, referral source) were examined along with characteristics of the clinic (clinicians, assessment outcome).ResultsA detailed description of the model is provided, including evident changes since the clinic began. Data were split between the 2007 to 2009 and 2010 to 2012 time periods to reflect changes in the operation of the clinic. Overall, 48 girls and 186 boys were assessed with a mean age of 71 months; the average waiting time between referral and assessment was 136.6 days. Across the two time periods, the proportion of children receiving a diagnosis of autism spectrum disorder increased from 43.1% to 66.3%. Changes are evident in the referral sources between the two time periods, and in the disciplines of clinicians involved in the assessment.ConclusionsThe research illustrates an assessment model, within the Victorian public health context, which currently operates effectively according to best‐practice guidelines. This research begins to fill a gap between localised clinical practice and the dissemination of this information to a wider audience, allowing for comparison for other assessment providers. It is hoped that we can contribute more broadly to future assessment processes becoming more consistent, reproducible and equitable for children suspected of having autism spectrum disorders.

AimThe composition of faecal microbiota of babies is known to be influenced by diet. Faecal calprotectin and α1‐antitrypsin concentrations may be associated with mucosal permeability and inflammation. We aimed to assess whether there was any difference after consumption of a probiotic/prebiotic formula on faecal microbiota composition, calprotectin and α1‐antitrypsin levels, and diarrhoea in comparison with breast milk‐fed Indonesian infants.MethodsOne hundred sixty infants, 2 to 6 weeks old, were recruited to the study. They were either breastfed or formula fed (80 per group). Faecal samples were collected at recruitment and 3 months later. Bacterial groups characteristic of the human faecal microbiota were quantified in faeces by quantitative polymerase chain reaction. Calprotectin and α1‐antitrypsin concentrations were measured using commercial kits. Details of diarrhoeal morbidity were documented and rated for severity.ResultsThe compositions of the faecal microbiota of formula‐fed compared with breast milk‐fed children were similar except that the probiotic strain Bifidobacterium animalis subsp. lactis DR10 was more abundant after 3 months consumption of the formula. Alpha1‐antitrypsin levels were higher in breastfed compared with formula‐fed infants. The occurrence of diarrhoea did not differ between the groups of babies.ConclusionFeeding Indonesian babies with a probiotic/prebiotic formula did not produce marked differences in the composition of the faecal microbiota in comparison with breast milk. Detrimental effects of formula feeding on biomarkers of mucosal health were not observed.
A REVIEW OF PERMO‐TRIASSIC RESERVOIR ROCKS IN THE ZAGROS AREA, SW IRAN: INFLUENCE OF THE QATAR‐FARS ARCH
Authors: Esrafili‐Dizaji B. , Rahimpour‐Bonab H. 
Published: June 2013

Four “supergiant” and numerous giant gasfields have been discovered in the Zagros area of SW Iran. The gasfields are concentrated in the eastern part of the foldbelt, in Fars Province and the adjacent offshore, and produce from Permo‐Triassic carbonates equivalent to the Khuff Formation. The carbonates belong to the upper member of the Dalan Formation and the overlying Kangan Formation. Reservoir rock quality is strongly influenced by tectonic setting and depositional environment, and also by diagenesis. The highest quality reservoirs occur in oolitic shoal facies; fracturing (especially in onshore fields) and dolomitisation (in offshore fields) have also influenced reservoir quality. Anhydrite plugging is common in reservoirs in offshore fields, while calcite cementation is dominant in onshore reservoirs.Facies variations in the Dalan‐Kangan Formations appear to correspond to syndepositional palaeohighs and depocentres. In the Eastern Zagros (Fars area), thickening of the Dalan Formation corresponds to a Mid‐Late Permian depocentre referred to here as the Permian Fars Basin. As a result of sea level fall, this depocentre evolved into a hypersaline lagoon with evaporite deposition (Nar Member). In the Triassic, the depocentre evolved into a palaeohigh as indicated by thinning and facies changes in the Kangan Formation.The results of this study draw attention to variations in the reservoir quality of the Dalan‐Kangan Formations. Much of this variation was due to the influence of the Qatar‐Fars Arch.
Challenges of the Harmonization and Ratification of Convention on the Rights of Persons With Disabilities by Japan
Authors: Osamu Nagase 
Published: June 2013

AbstractThere are 130 ratifications by national governments around the world of the Convention on the Rights of Persons with Disabilities (CRPD), adopted by the United Nations in December 2006. However, Japan has yet to ratify the CRPD. The author examined the social, political, and legal context in Japan, affecting the ratification of the CRPD and contrasted the approach taken by Japan with those of other countries that have ratified the CRPD and then embarked on local reforms. The author notes that in Japan, the disability rights movement has insisted that significant policy changes be undertaken before the government ratifies the CRPD. Consequently, in 2010, the Japanese government prepared a roadmap for ratification of the CRPD, which consisted of (1) a fundamental revision undertaken in 2011 of the Basic Law for Persons with Disabilities, including the fundamental principles of community living, prohibition of disability discrimination, and international partnerships; (2) a revision of services legislation in 2012; and (3) proposed for 2013, an establishment of an independent law to prohibit disability discrimination. Other areas of legislation and policy that underwent review include the education of children with disabilities, the prevention of abuse of persons with disabilities, and support to carers and the political rights of persons under adult guardianship. The author notes that there are a number of challenges ahead for the implementation of the CRPD and consequently the promotion of community living. However, it is posited that the comprehensive legislative and policy reform undertaken by the government of Japan, prior to ratification of the CRPD, will lay important foundations to enable Japan to fully comply with and take a leadership role in the implantation of the CRPD.
The World Report on Disability and People With Intellectual Disabilities
Authors: Officer Alana , Shakespeare Tom 
Published: June 2013

AbstractThe World Report on Disability was requested by the World Health Assembly, the governing body of the World Health Organization (WHO). Because disability is broader than health, WHO partnered with the World Bank. The World Report was published in 2011 and provides a comprehensive scientific analysis on the global situation of people with disability that can support the implementation of the United Nations Convention on the Rights of Persons with Disability. Progress since the global launch of the Report in June 2011 has shown areas of awareness raising, policy development, funding, research, and technical support. Yet gaps exist, and there is a need to better inform policy and practice with particular reference to intellectual disability. The World Report on Disability makes nine recommendations: enable access to mainstream policies, systems, and services; invest in specific programs and services for people with disabilities; adopt a national disability strategy and plan of action; involve people with disabilities; improve human resource capacity; provide adequate funding and improve affordability; increase public awareness and understanding of disability; improve disability data collection; and strengthen and support research on disability. The World Report on Disability has increased awareness and understanding of issues affecting people with disability, and is serving to focus government attention on policies and programs that will support the implementation of the United Nations Convention on the Rights of Persons with Disability, 2006. Particularly in the world's poorest countries, people with intellectual disabilities are disproportionately disadvantaged. The World Report is an important tool to build a global commitment to the promotion of inclusion for all persons with disabilities, and especially those with intellectual disability.
