Background—
Early stent valve thrombosis after transcatheter aortic valve implantation (TAVI) is a rare complication, which is diagnosed based on the appearance of clinical symptoms of heart failure and echocardiographic findings. After TAVI, transthoracic echocardiography is performed to assess transcatheter heart valve (THV) function. However, preliminary reports indicate the potential additive clinical value of multidetector computed tomography (MDCT) for the diagnosis of THV thrombosis. We sought to determine the value of MDCT for the diagnosis of THV thrombosis and the frequency of this complication after balloon-expandable TAVI.

Methods and Results—
MDCT was performed in 140 patients within 1 to 3 months after TAVI with the Edwards Sapien XT THV to assess the presence of THV thrombosis and THV stent geometry. Post-TAVI MDCT identified THV thrombosis in 5 patients (4%). Of note, 4 of these patients were asymptomatic and had a normal transthoracic echocardiographic examination without signs of thrombus formation or flow obstruction. In patients with THV thrombosis, a left ventricular ejection fraction of <35% was present in 3 (60%), whereas 2 (40%) did not receive standard post-TAVI dual-antiplatelet therapy. Neither THV underexpansion nor THV noncircularity was detected in patients with THV thrombosis.

Conclusions—
Post-TAVI MDCT is a valuable tool for the diagnosis of THV thrombosis, and this complication seems to be more common than previously anticipated. Larger studies are required to identify specific risk factors of THV thrombosis.

Published: April 2015

Background—
Transcatheter aortic valve implantation (TAVI) is an advancing mode of treatment for inoperable or high-risk patients with aortic stenosis. Prosthetic valve endocarditis (PVE) after TAVI is a serious complication, but only limited data exist on its incidence, outcome, and procedural risk factors.

Methods and Results—
Observational single-center study of 509 consecutive patients treated with a transcatheter implanted self-expandable aortic valve prosthesis (Medtronic CoreValve). We identified 18 patients diagnosed with TAVI-PVE during a median follow-up period of 1.4 years (interquartile range, 0.5–2.5 years; longest follow-up was 6.3 years). TAVI-PVE was most frequent in the first year after implantation (first-year incidence, 3.1% [confidence interval, 1.4%–4.8%]); the overall annualized rate was 2.1% per patient-year (confidence interval, 1.2%–3.3%). Seventeen patients (94%) were treated conservatively and 1 with surgery. Four patients (22%) died from endocarditis or complications to treatment, 2 of those (11%) during initial hospitalization for PVE. An increased risk of TAVI-PVE was seen in patients with low implanted valve position (hazard ratio, 2.8 [1.1–7.2]), moderate or worse postprocedural paravalvular regurgitation (hazard ratio, 4.0 [1.5–11]), implantation of >1 prosthesis (hazard ratio, 5.2 [1.5–18]), and any vascular complication (hazard ratio, 3.8 [1.5–9.8]).

Conclusions—
TAVI-PVE occurred at a slightly higher rate than reported for surgically implanted valves. Conservative treatment was associated with an acceptable outcome. Suboptimal valve deployment and vascular complications were associated with an increased risk of TAVI-PVE.

Published: April 2015

Background—
Severe tricuspid valve (TV) dysfunction may lead to surgical TV replacement with a biological valve prosthesis in patients with congenital heart disease. To expand the lifetime of this valve and reduce the number of surgeries, percutaneous TV implantation (PTVI) may be an effective alternative to repeated surgery. We report on our 2-center experience with PTVI.

Methods and Results—
Between 2008 and 2014, 17 percutaneous valves were implanted in 16 patients with TV bioprosthesis dysfunction (9 females) from 2 centers. Median age and weight were 31.3 years (5–77.2) and 65.2 kg (17.7–107); 14 patients had congenital heart disease (univentricular heart with a right atrial to right ventricle bioprosthesis in 3, Ebstein’s anomaly of the TV in 5, and other in 6), and 2 had acquired TV dysfunction. All procedures were successful (Melody n=7, Sapien 26 mm valve n=4, Sapien XT 29 mm valve n=6). One valve showed early dysfunction. It was replaced surgically and shortly after that a repeated PTVI was performed. The median duration of follow-up was 2.1 years (3 days to 6.3 years). The percutaneous valve was performing well in 15 of 16 patients.

Conclusions—
PTVI was safe and effectively improved TV function in all but 1 patient at midterm follow-up. We think that PTVI is a good alternative to repeated surgical TV replacements and that it may reduce the total number of open heart surgeries in these patients.

Authors: Agarwal Sunil K. , Chao Jennifer , Peace Frederick , Judd Suzanne E. , Kissela Brett , Kleindorfer Dawn , Howard Virginia J. , Howard George , Soliman Elsayed Z. 
Published: April 2015

Background and Purpose—
Premature ventricular complexes (PVCs) detected from long-term ECG recordings have been associated with an increased risk of ischemic stroke. Whether PVCs seen on routine ECG, commonly used in clinical practice, are associated with an increased risk of ischemic stroke remains unstudied.

Methods—
This analysis included 24 460 participants (aged, 64.5+9.3 years; 55.1% women; 40.0% blacks) from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study who were free of stroke at the time of enrollment. PVCs were ascertained from baseline ECG (2003–2007), and incident stroke cases through 2011 were confirmed by an adjudication committee.

Results—
A total of 1415 (5.8%) participants had at least 1 PVC at baseline, and 591 developed incident ischemic stroke during an average (SD) follow-up of 6.0 (2.0) years. In a cox proportional hazards model adjusted for age, sex, race, geographic region, education, previous heart disease, systolic blood pressure, blood pressure–lowering medications, current smoking, diabetes mellitus, left ventricular hypertrophy by ECG, and aspirin use and warfarin use, the presence of PVCs was associated with 38% increased risk of ischemic stroke (hazard ratio [95% confidence interval], 1.38 [1.05–1.81]).

Conclusions—
PVCs are common on routine screening ECGs and are associated with an increased risk of ischemic stroke.
A new species of Afropinnotheres Manning, 1993 (Crustacea, Brachyura, Pinnotheridae) from southwestern India, the first record of the genus from the Indian Ocean, with a review of the Pinnotheridae of India and adjacent seas

Published: April 2015

A new species of pinnotherid crab of the genus Afropinnotheres Manning, 1993, is described from the brown mussel, Perna perna (Linnaeus, 1758), in southwestern India. This is the first record of the genus from the western Indian Ocean, the other four species been recorded from the eastern Atlantic. The new species can be distinguished from all congeners in possessing a more rounded male carapace, form of the chela, relatively longer ambulatory legs which have no natatory setae, presence of dense pubescence on the male ambulatory legs, and the shape of the male and female telsons. The Indian Pinnotheridae is also reviewed and the taxonomy of the species reappraised. The taxonomy of Pinnaxodes Heller, 1865, and Holothuriophilus Nauck, 1880, is also discussed, in the context of their similarity to Afropinnotheres.
Methods to Calculate Precipitation from Weighing-Bucket Gauges with Redundant Depth Measurements
Authors: Leeper Ronald D. , Palecki Michael A. , Davis Egg 
Published: April 2015

AbstractThe U.S. Climate Reference Network (USCRN) monitors precipitation using a well-shielded Geonor T-200B gauge. To ensure the quality and continuity of the data record, the USCRN adopted an innovative approach to monitor precipitation using redundant technology: three vibrating-wire load sensors measuring the liquid depth of a weighing-bucket gauge. In addition to detecting and flagging suboptimally operating sensors, quality assurance (QA) approaches also combine the redundant observations into a precipitation measurement. As an early adopter of this technology, USCRN has pioneered an effort to develop QA strategies for such precipitation systems.The initial USCRN approach to calculating precipitation from redundant depth observations, pairwise calculation (pairCalc), was found to be sensitive to sensor noise and gauge evaporation. These findings led to the development of a new approach to calculating precipitation that minimized these nonprecipitation impacts using a weighted average calculation (wavgCalc). The two calculation approaches were evaluated using station data and simulated precipitation scenarios with a known signal. The new QA system had consistently lower measures of error for simulated precipitation events. Improved handling of sensor noise and gauge evaporation led to increases in network total precipitation of 1.6% on average. These results indicate the new calculation system will improve the quality of USCRN precipitation measurements, making them a more reliable reference dataset with the capacity to monitor the nation’s precipitation trends (mean and extremes). In addition, this study provides valuable insight into the development and evaluation of QA systems, particularly for networks adopting redundant approaches to monitoring precipitation.
Measuring Team Cohesion
Authors: Salas Eduardo , Grossman Rebecca , Hughes Ashley M. , Coultas Chris W. 
Published: April 2015

Objective: The aim of this study was to review literature relevant to cohesion measurement, explore developing measurement approaches, and provide theoretical and practical recommendations for optimizing cohesion measurement. Background: Cohesion is essential for team effectiveness and performance, leading researchers to focus attention on understanding how to enhance it. However, cohesion is inconsistently defined and measured, making it difficult to compare findings across studies and limiting the ability to advance science and practice. Method: We reviewed empirical research through which we uncovered specific information about cohesion’s conceptualization, measurement, and relationships with performance, culminating in a set of current trends from which we provide suggestions and possible solutions to guide future efforts and help the field converge toward greater consistency. Results: Cohesion demonstrates more significant relationships with performance when conceptualized using social and task (but not other) dimensions and when analyses are performed at the team level. Cohesion is inherently temporal, yet researchers rarely measure cohesion at multiple points during the life of a team. Finally, cohesion matters in large, dynamic collectives, complicating measurement. However, innovative and unobtrusive methodologies are being used, which we highlight. Conclusion: Practitioners and researchers are encouraged to define cohesion with task and social subdimensions and to measure with behavioral and attitudinal operationalizations. Individual and team-oriented items are recommended, though team-level analyses are most effective. Innovative/unobtrusive methods should be further researched to enable cohesion measurement longitudinally and in large, dynamic collectives. Application: By applying our findings and conclusions, researchers and practitioners will be more likely to find consistent, reliable, and significant cohesion-to-performance relationships.

Published: April 2015

Introduction There is a shortage of tools designed for use by occupational therapy practice in Arabic-speaking countries. The purpose of this study was to translate and cross-culturally adapt the original Satisfaction with Daily Occupations tool to Arabic and assess the psychometric properties of the adapted tool. Method A cross-cultural adaptation process was performed. Face, content, and criterion validity were examined, as well as internal consistency and test–retest reliability. The study included 147 healthy adults and 73 patients with cerebrovascular accident. They were purposefully selected from two countries (Kuwait and Jordan). Results The adapted tool comprised six domains and a total of 14 items. Face and content validity were established through prolonged content analysis. Criterion validity was indicated by significant differences between the healthy and the cerebrovascular accident group in all areas of the Satisfaction Daily Occupations scale ( p < 0.001). Satisfactory overall internal consistency (α = 0.77) and good test–retest reliability for the total satisfaction score for the healthy (inter-class correlation coefficient (ICC) = 0.984) and the cerebrovascular accident group (inter-class correlation coefficient (ICC) = 0.933) were found. Conclusions The Satisfaction with Daily Occupations-Arabic version is a valid and reliable tool for use with Arabic-speaking occupational therapy clients. This study has several implications for occupational therapy education, practice, and research in the Arab world.

Published: April 2015

Introduction Measuring occupational performance is an essential part of clinical practice; however, there is little research on service user perceptions of measures. The aim of this investigation was to explore the acceptability and utility of one occupational performance outcome measure, Goal Attainment Scaling, with young people (12–25 years old) seeking psychological help. Method Semi-structured interviews were conducted with ten young people seeking help from a youth mental health clinic. Interviews were audio taped and a field diary kept. Interviews were transcribed verbatim and analysed using content analysis. Results were verified by member checking. Results All participants were able to engage in using Goal Attainment Scaling to set goals for therapy, and reported the process to be useful. The participants identified the physical location and ownership of the scale was important to help motivate them to work on their goals. Conclusion Young help-seekers see Goal Attainment Scaling as an acceptable tool to facilitate the establishment of functional goals. Young service users were particularly keen to maintain control over the physical location of completed forms.
WOW! Occupational therapy education and experiential service learning through community volunteering
Authors: Parmenter Vanessa , Thomas Holly 
Published: April 2015

Introduction This research investigated the contribution of ‘Widening Occupation Weeks’, a two-week experience of occupation-focused service learning through community volunteering, to undergraduate occupational therapy education. Method A pluralist research methodology combining psychosocial approaches with cooperative appreciative inquiry and grounded theory was used in order to explore individual experiences and collective understanding. Students participated in questionnaires and a focus group to: explore how Widening Occupation Weeks impacted on understanding of the relationship between occupation, health and wellbeing; discover students’ interpretation of significant learning; develop a general view of the relevance of Widening Occupation Weeks for occupational therapy education. Results Thematic analysis of qualitative data identified that students’ experience during Widening Occupation Weeks is diverse and variable, enabling learning about the occupational therapy paradigm and about the values involved in being a therapist: therapeutic relationships and professionalism. Significant learning occurs through reflection over time on the challenging, contrasting experiences offered by the Widening Occupation Weeks model. This contributes to the development of personal theories of practice, recognised as a key component in professional socialisation and innovation. Conclusion The pluralist methodology enabled perspectives on personal and collective interpretation of learning and the findings can be translated to a general theory about the value of occupation-focused, service learning in occupational therapy education.

Authors: Bassi Andrea M. , De Rego Frank , Harrisson John , Lombardi Niccolò 
Published: April 2015

Background: Sustainable management of the municipal water supply is a priority issue in the policy agenda of Maui County, Hawaii. The Maui Economic Development Board launched the WaterStory initiative to educate residents about the determinants and history of Maui’s water resource development. A System Dynamics model was developed and coupled with a user interface to create WATERSTORY, an interactive learning environment (ILE). Purpose: The purpose of this study was to analyze the benefits of WATERSTORY for the identification and assessment of sustainable water management policies in Maui. Method: WATERSTORY is a System Dynamics-based ILE that shows the cross-sectoral impacts of users’ decisions. Both, the simulation model and the ILE resulted from group modeling and ILE testing sessions. Results: The development of the WATERSTORY ILE facilitated the involvement of local communities in the discussion of water management problems and identification of possible solutions. Conclusions: The study suggests that developing a simple ILE is essential in raising the interest of a wide audience involved in sustainable development policy making. After stakeholders gain confidence in the benefit of the ILE, it becomes easier to integrate simulation exercises into planning processes at national, regional and local levels.

Published: April 2015

Background: The standard ISO (International Organization for Standardization) 15197 is widely accepted for the accuracy evaluation of systems for self-monitoring of blood glucose (SMBG). Accuracy evaluation was performed for 4 SMBG systems (Accu-Chek® Aviva, Contour®XT, GlucoCheck XL, GlucoMen® LX PLUS) with 3 test strip lots each. To investigate a possible impact of the comparison method on system accuracy data, 2 different established methods were used. Methods: The evaluation was performed in a standardized manner following test procedures described in ISO 15197:2003 (section 7.3). System accuracy was assessed by applying ISO 15197:2003 and in addition ISO 15197:2013 criteria (section 6.3.3). For each system, comparison measurements were performed with a glucose oxidase (YSI 2300 STAT Plus™ glucose analyzer) and a hexokinase (cobas® c111) method. Results: All 4 systems fulfilled the accuracy requirements of ISO 15197:2003 with the tested lots. More stringent accuracy criteria of ISO 15197:2013 were fulfilled by 3 systems (Accu-Chek Aviva, ContourXT, GlucoMen LX PLUS) when compared to the manufacturer’s comparison method and by 2 systems (Accu-Chek Aviva, ContourXT) when compared to the alternative comparison method. All systems showed lot-to-lot variability to a certain degree; 2 systems (Accu-Chek Aviva, ContourXT), however, showed only minimal differences in relative bias between the 3 evaluated lots. Conclusions: In this study, all 4 systems complied with the evaluated test strip lots with accuracy criteria of ISO 15197:2003. Applying ISO 15197:2013 accuracy limits, differences in the accuracy of the tested systems were observed, also demonstrating that the applied comparison method/system and the lot-to-lot variability can have a decisive influence on accuracy data obtained for a SMBG system.
Quetiapine versus aripiprazole in the management of schizophrenia
Authors: Shoja Shafti Saeed , Kaviani Hamid 
Published: April 2015

Objectives: Current evidence supports the use of various second-generation antipsychotics for pharmacotherapy of schizophrenia. While in a systematic review, generally no difference in efficacy was found between atypical antipsychotics, other studies have found quetiapine less effective than aripiprazole. This article reviews the efficacy and tolerability of aripiprazole versus quetiapine in the context of recommended management strategies for schizophrenia. Method: Fifty female inpatients, meeting the diagnosis of schizophrenia, were randomly entered into two groups ( n = 25 in each group) to participate in a 12-week, double-blind study for random assignment to quetiapine or aripiprazole. The primary outcome measures were Scale for Assessment of Positive Symptoms and Scale for Assessment of Negative Symptoms. The schedule for Assessment of Insight (SAI), Clinical Global Impressions Severity Scale (CGI-S) and the Simpson Angus Scale (SAS) were also used as secondary measures. Results: Both quetiapine and aripiprazole showed significant effectiveness in the improvement of positive symptoms. The effectiveness for negative symptoms was also noteworthy with both drugs, although not to a significant level during this study. In addition, significant improvement was found on assessment with CGI-S and SAI for quetiapine and aripiprazole. SAS did not show any important increment in extrapyramidal side effects at the end of the examination. Conclusion: According to the findings, quetiapine and aripiprazole had similar effectiveness and tolerability with respect to management of schizophrenia.
