Estimation of ventricular contractility and ventricular arterial coupling is clinically important in diagnosing and treating cardiac dysfunction in the critically ill. However, experimental assessment of indexes of ventricular contractility, such as the end-systolic pressure-volume relationship, requires a highly invasive maneuver and measurements that are not typical in an intensive care unit (ICU). This research describes the use of a previously validated cardiovascular system model and parameter identification process to evaluate the right ventricular arterial coupling in septic shock. Model-based ventricular arterial coupling is defined by the ratio of the end systolic right ventricular elastance (E(esrvf)) over the pulmonary artery elastance (E(pa)) or the mean pulmonary inflow resistance (R(pulin)). Results are compared to the clinical gold-standard assessment (conductance catheter method). Six anesthetized healthy pigs weighing 20-30kg received a 0.5mgkg(-1) endotoxin infusion over a period of 30min from T0 to T30, to induce septic shock and veno-venous hemofiltration was used from T60 onward. The results show good agreement with the gold-standard experimental assessment. In particular, the model-based right ventricular elastance (E(esrvf)) correlates well with the clinical gold standard (R(2)=0.69) and the model-based non-invasive coupling (E(esrvf)/R(pulin)) follow the same trends and dynamics (R(2)=0.37). The overall results show the potential to develop a model-based sensor to monitor ventricular-arterial coupling in clinical real-time. [less ▲]

BACKGROUND:: Existing methods to predict recovery after severe traumatic brain injury lack accuracy. The aim of this study is to determine the prognostic value of quantitative diffusion tensor imaging (DTI). METHODS:: In a multicenter study, the authors prospectively enrolled 105 patients who remained comatose at least 7 days after traumatic brain injury. Patients underwent brain magnetic resonance imaging, including DTI in 20 preselected white matter tracts. Patients were evaluated at 1 yr with a modified Glasgow Outcome Scale. A composite DTI score was constructed for outcome prognostication on this training database and then validated on an independent database (n = 38). DTI score was compared with the International Mission for Prognosis and Analysis of Clinical Trials Score. RESULTS:: Using the DTI score for prediction of unfavorable outcome on the training database, the area under the receiver operating characteristic curve was 0.84 (95% CI: 0.75-0.91). The DTI score had a sensitivity of 64% and a specificity of 95% for the prediction of unfavorable outcome. On the validation-independent database, the area under the receiver operating characteristic curve was 0.80 (95% CI: 0.54-0.94). On the training database, reclassification methods showed significant improvement of classification accuracy (P < 0.05) compared with the International Mission for Prognosis and Analysis of Clinical Trials score. Similar results were observed on the validation database. CONCLUSIONS:: White matter assessment with quantitative DTI increases the accuracy of long-term outcome prediction compared with the available clinical/radiographic prognostic score. [less ▲]

Renewable technologies are considered as clean sources of energy and optimal use of these resources minimize environmental impacts, produce minimum secondary wastes and are sustainable based on current and future economic and societal needs. Renewable energy technologies provide an excellent opportunity for mitigation of greenhouse gas emission and reducing global warming through substituting conventional energy sources. In the Sahel of West Africa, dramatically affected by desertification processes and rainfall shortages, wind energy is often viewed as a technology to mitigate deforestation although its development is extremely limited. The purpose of this study is to assess wind power potential in Niamey, Niger, a country where forest areas have declined by 34.5% over the 1990-2005 period. From 3-hourly meteorological data collected at the Niamey-Airport synoptic station over ten years (1998-2007), we evaluate the wind speed characteristics and the wind power potential at a height of 10 meters above ground level at diurnal, monthly, and yearly scales. We find very large differences in wind speed at the diurnal (2.40 – 5.11 m/s), monthly (2.61 – 4.11 m/s) and yearly (3.21 – 3.73 m/s) scales, with a global average wind speed of 3.42 m/s. We conclude that the wind powered energy is not economically feasible in Niamey due to its low wind potential. [less ▲]

Objective:Integration of e-Health technologies for purposes of both assessment and intervention has recently become an interest area in pediatric psychology. The purpose of this study is to present psychometric characteristics of a technology-based (i.e., iPad administration) approach for measuring quality of life (QoL) in children. Methods: Sample consisted of 80 children (8-12 years) recruited from elementary schools in Belgium. They completed the Quality of Life Systemic Inventory for Children (QLSI-C) twice over a two-week delay, in a crossover design that used paper and iPad-based modes of administration. QLSI-C takes a unique approach to assessing QoL relative to existing measures. Specifically, it considers QoL to be the difference (gap score) between the present situation (state score) and the child’s expectations (goal), weighted by the importance (rank) assigned for each life domain. Cronbach’s coefficient was computed to assess internal consistency for each of the four global scores (State, Goal, Gap, Rank). ANOVA was used to assess the equivalence of the new iPad and paper formats. Test-retest reliability was assessed using correlational analysis. Results: Alpha coefficients for the global scores were as follows: State (.87), Goal (.94), Gap (.72), and Rank (.79). ANOVA results indicate that main effects for group (p = 0.75) and time (p= 0.31) were not statistically significant, nor was the interaction effect (p = 0.86) for the QoL score (Gap). Correlations for the test-retest reliability of the 4 global scores ranged from .66 to .90. Conclusions: The iPad format of QLSI-C appears valid in comparison to the original paper format and test-retest stability for the iPad format is good. This technology approach to assessment is more attractive for children, decreases time for administration, and enhances the ease of scoring. Thus, these advantages might encourage both clinicians and researchers to consider using e-Health developments in assessment in pediatric psychology. [less ▲]
