Abstract:

AbstractComparative studies of aging are often difficult to interpret because of the different factors that tend to correlate with longevity. We used the AnAge database to study these factors, particularly metabolism and developmental schedules, previously associated with longevity in vertebrate species. Our results show that, after correcting for body mass and phylogeny, basal metabolic rate does not correlate with longevity in eutherians or birds, although it negatively correlates with marsupial longevity and time to maturity. We confirm the idea that age at maturity is typically proportional to adult life span, and show that mammals that live longer for their body size, such as bats and primates, also tend to have a longer developmental time for their body size. Lastly, postnatal growth rates were negatively correlated with adult life span in mammals but not in birds. Our work provides a detailed view of factors related to species longevity with implications for how comparative studies of aging are interpreted.

Abstract:

Computer self-efficacy (CSE) has been a popular and important construct in information systems research for more than two decades. Although CSE researchers have conducted extensive qualitative reviews, quantitative analyses are lacking for studies of the relationships between CSE and variables of interest. This study provides such a quantitative analysis. The authors meta-analyze 102 empirical CSE studies that reported 232 usable statistical relationships between CSE and seven correlates. Their main meta-analysis demonstrates that CSE is significantly correlated in the theoretically predicted direction with each of the seven correlates. They also quantitatively assess five study characteristics as potential moderators of the CSE-correlate relationships. The moderator analysis reveals complex patterns and indicates that more research is needed to investigate possible moderating effects.

Abstract:

ABSTRACT Introduction Injury mechanics of blunt impact projectiles differ from those experienced in whole body motor vehicle collisions because the effects are localized around the point of impact, and thus, injury thresholds based upon gross chest kinematics (e.g., force, velocity) may not be applicable across impact types. Therefore, knowledge of biomechanically based tissue injury correlates for blunt impact projectiles are needed to better guide design and development of protective systems as well as assess injury risks from blunt impact projectile weapons. Materials and Methods In this study, subject-specific swine finite element models were used to quantify the tissue-level stresses and strains resulting from high speed projectile impact. These tissue-level injury doses were correlated to pathology injury outcomes to produce injury risk curves for lung contusion. Details of the pathology data and finite element results are provided in Appendix 1. Survival analysis regression methods were applied to develop lung injury regression curves and a number of statistical methods were used to evaluate several biomechanical metrics as correlates to lung contusion. Uncertainty and sensitivity analyses were used to further confirm the selection of the correlate. Results Statistical analysis revealed that normalized strain-energy density was the best correlate for prediction of lung tissue damage. Going further, normalized strain-energy density also proved to be suitable for prediction of the percentage of contused lung volume, a more meaningful medical diagnosis. As expected, peak strain-energy density is most sensitive to muscle-skin properties, as quantified through a comprehensive uncertainty and sensitivity analysis over three sets of projectile weights and speeds. Conclusions Normalized strain-energy density was found to be the best correlate for prediction of lung tissue damage and correlate well to extent of contused lung volume.

Abstract:

Purpose. To correlate the uveitic epiretinal membrane (ERM) features using spectral-domain optical coherence tomography (SD-OCT) with visual acuity (VA).Methods. Forty-one eyes of 32 patients were included in this retrospective study. SD-OCT was performed in all patients and data were collected at the time of ERM diagnosis and at the final visit. Both best corrected visual acuity (BCVA) and ERM thickness were correlated with the morphological and clinical features.Results. Final BCVA was positively correlated with male sex and the focal pattern of ERM attachment and negatively correlated with IS/OS photoreceptor junction disruption . BVCA change showed a positive correlation with the age of ERM onset but a negative correlation with IS/OS photoreceptor disruption at the ERM diagnosis and the increase of central subfield thickness (CST) . Final ERM thickness correlated with the duration of uveitis and the duration of ERM . During the follow-up, ERM thickening correlated with male sex , posterior uveitis , uveitis duration , and broad attachment pattern .Conclusions. In the uveitic ERM, VA negatively correlates with IS/OS photoreceptor junction disruption and the increase of CST. ERM thickness is influenced by longer duration of both uveitis and ERM.

Abstract:

The factor structure as well as criterion-related validity of Argumentativeness were examined in three independent samples ( N = 811) with correlations including confirmatory factor analysis. Factor scores show that Approach-oriented and Avoidance-oriented Argumentativeness are negatively correlated. In addition, a factor of Evaluation of Argumentative Skills was established for self-ratings and peer-ratings. Scores on Avoidance-oriented Argumentativeness correlate strongly with Compliance and scores on Approach-oriented Argumentativeness correlate low with Assertiveness. Scores of Approach-oriented Argumentativeness correlate with Openness to Experience from the NEO-Five Factor Inventory and scores of Avoidance-oriented Argumentativeness with Neuroticism. Self-evaluations and evaluations by two independent raters in an adult sample were positively correlated.

Full text

Abstract:

Previous studies have correlated interannual streamflow fluctuations with changes in the climate. We note that decadal shifts in climate forcing can impart a stronger signal on streamflow than does the long-term climatic trend. In north-western North America, the Pacific Decadal Oscillation (PDO), which is strong in the cold season, may exert influence on interannual variations in spring high flows. In the 20th century, several major shifts in the PDO have been recognized. However, the rivers of Alaska, Yukon, Northwest Territories, British Columbia and Alberta have variable response to such climate signals. An analysis of the flow of rivers in this region indicates that a number of rivers draining the Pacific coast are positively correlated with PDO and some rivers in the interior correlate negatively. Not all river flows correlate with the PDO because factors such as location, topography and storage can overwhelm the climatic influence. Given these considerations, the interpretation of long-term trends in streamflow should take account of the interdecadal climatic shifts and basin characteristics that affect flow generation.

Abstract:

Generalizability, psychological symptom correlates, and the factor structure of the Health Professions Stress Inventory were assessed with a sample of 92 geriatric nurses. The inventory was designed to measure the sources and frequency of stress among nurses, physicians, and pharmacists; little is known, however, of the extent to which scores correlate with psychological symptoms or of the underlying dimensions of stress measured. Analyses showed high correspondence between responses of the geriatric nurses and the normative nurses as measured by mean values and Cronbach alpha. Factor analysis of the intercorrelations among items yielded 4 factors contributing to work-related stress, i.e., Lack of Perceived Enrichment Potential, Patient Care, Interpersonal Conflict, and Family Responsibility Conflict. Scores on the inventory correlated significantly with those of all SCL-90—R scales.

Abstract:

In order to determine if the expression of the activation marker CD38 can correlate with HIV disease progression independently of cycling, we performed a cluster-based multivariate correlation analysis of total circulating CD4+T cell counts and viral loads with frequencies of CD38 and Ki67 expression on CD4+lymphocytes from patients with untreated HIV infection, stratified in maturation subpopulations, and subpopulation subsets defined by the expression of CXCR5, CXCR3, and CCR4. The frequencies of the activated phenotypes %CD38+Ki67−and %CD38+Ki67+of the CXCR5−CXCR3−CCR4+(“pre-Th2”) central memory (TCM) cell subset clustered together, comprising a significant negative correlate of total circulating CD4+T cell counts and a positive correlate of viral load in multivariate analysis. Frequency of cycling-uncoupled CD38 expression in “pre-Th2”TCMcells was a negative correlate of total circulating CD4+T cell counts in univariate analysis, which was not the case of their %CD38+Ki67+. CXCR5+CXCR3−CCR4− TCMcells were underrepresented in patients, and their absolute counts correlated negatively with their %CD38+Ki67−but not with their % CD38+Ki67+. Our results may imply that CD38 expression either reflects or participates in pathogenic mechanisms of HIV disease independently of cell cycling.

Abstract:

Objective The objective of this study was to test whether hospitals experienced in twin delivery have lower rates of cesarean delivery for twins. Methods We divided obstetric hospitals in the 2011 National Inpatient Sample by quartile of annual twin deliveries and compared twin cesarean delivery rates between hospitals with weighted linear regression. We used Pearson's coefficients to correlate a hospital's twin cesarean delivery rate to its overall cesarean delivery and vaginal birth after cesarean (VBAC) rates. Results Annual twin delivery volume ranged from 1 to 506 across the 547 analyzed hospitals with a median of 10 and mode of 3. Adjusted rates of cesarean delivery were independent of delivery volume with a rate of 75.5 versus 74.8% in the lowest and highest volume hospitals (p = 0.09 across quartiles). A hospital's cesarean delivery rate for twins moderately correlated with the overall cesarean rate (r = 0.52, p < 0.01) and inversely correlated with VBAC rate (r = − 0.42, p < 0.01). Conclusion Most U.S. obstetrical units perform a low volume of twin deliveries with no decrease in cesarean delivery rates at higher volume hospitals. Twin cesarean delivery rates correlate with other obstetric parameters such as singleton cesarean delivery and VBAC rates suggesting twin cesarean delivery rate is more closely related to a hospital's general obstetric practice than its twin delivery volume.

Abstract:

e18008 Background: Nivolumab is approved for 2nd line R/M SCCHN, but only ̃20% of patients will benefit. Therefore, there is an unmet need for predictive markers. Nivactor is a prospective real-life study of nivolumab in SCC-HN. We report an ancillary study on circulating cytokines in a subgroup of patients from Nivactor. Methods: We analysed changes of circulating cytokines (IL-2/4/5/6/8/10/12/13/15, CCL-2/4/22, CXCL-10, IFN-γ, TGF-β, TNF-α, VEGF) during nivolumab therapy at baseline (T0), cycle 3 (T1), cycle 7 (T2) and at disease progression (TPD). ROC analysis identifies cytokines that correlate best with PFS and OS and calculate cut-off points. Cox analysis was performed to assess HR. Hierarchical Clustering on Principal Components (HCPC) was performed to cluster pts and then compared clusters for good or poor PFS and OS. Correction for multiplicity was applied. Results: 19 pts were analysed. Using ROC analysis, we were able to identify cut-off values correlated with PFS at T0 only for IL-6 and IL-10. Similarly, we identified IL-6, IL-10, TGF-β and VEGF cut-off for OS. Then we performed Cox analysis dividing the population based on the identified cut-offs and we found that pts with IL-6 or IL-10 lower than cut off had a significant better PFS and OS (p = 0.049 and p = 0.003 for PFS, respectively; p = 0.029 and p = 0.006 for OS, respectively). TGF-β lower than cut-off correlates with better OS (p = 0.02). Interestingly, pts with all the 3 cytokines below the cut-off show the best OS. Finally, we performed a multivariate analysis using HCPC to identify 4 clusters of pts. Cluster 2 has the best PFS and OS than all other cluster considered together (p = 0.001 and p = 0.004 respectively). Patients in cluster 2 show at T0 lower IL-6/10/15 and at T1 lower IL-5/10 and higher IFN-γ compared to the others. Longitudinal analysis among the 3 time points shows that the increase of IFN-γ, IL-5 and IL-10 between T0 and T1 correlates with better PFS (p = 0.01, p = 0.03, p = 0.02, respectively); only IFN-γ and IL-5 correlates with better OS (p = 0.04; p = 0.02, respectively). Conclusions: ROC analysis can identify cytokines whose basal level may predict patients that could benefit from nivolumab treatment: low IL-6 and IL-10 positively influence both PFS and OS. Low TGF-β does not correlate with PFS but only with better OS and can be considered a pure prognostic marker. Longitudinal analysis offers information on the effect of treatment on circulating cytokines, and show that the subgroup of pts with better PFS exhibits an increase of inflammatory cytokines values.

Abstract:

According to Ayurveda dhatus (structural entities) are circulating through a channel known as srotas, these strotas carry dhatu (tissue elements or their constituent) undergoing transformation to their destination. Each srotas has 2 mulasthan (roots), which are different according to various text of Ayurveda. Different Acharyas describe roots of Medowaha srotas differently upto some extent, with this context the exploration of this concept is needed with respect to modern science which is mostly based on Pratyaksha pramana. An Ayurvedic principle, to treat the diseases of respective srotas, root site has to be treated. About medowaha srotas, out of two roots one is “Vrikka” is common in all text, but the second root is different with this context exploration is needed. When we correlate term Vrikka with kidney, we can’t full fill the aspect of Meda (fat) metabolism but if Vrikka is correlates with kidney plus suprarenal gland then we can. In Structure suprarenal gland are attached to kidneys on superior side kidneys and suprarenal glands are made up of same tissue. The diseases of Meda dhatu given by compendia are correlated with diseases of hormone cortisol secreated by suprarenal gland, and cortisol is responsible for fat metabolism. Even suprarenal glands are not described in any text of Ayuurveda. The second roots given by Acharyas are Vapawahan, kati, Mansa and Jatharmeda respectively all these structures are deposited with adipose tissue having adipocyte. During starvation this tissue is metabolized and used for energy. So, these all structures are roots of Medowaha srotas.

Abstract:

Background Whether passive measures of isokinetic muscle strength deficits and knee laxity are related to the dynamic function of the anterior cruciate ligament-deficient knee remains unclear. Hypotheses Arthrometer measurements are not predictive of peak external knee flexion moment (net quadriceps muscle moment), isokinetic quadriceps muscle strength correlates with peak external knee flexion moment (net quadriceps muscle moment), and isokinetic hamstring muscle strength correlates with peak external knee extension moment (net flexor muscle moment). Study Design Cross-sectional study. Methods Gait analysis was used to assess dynamic function during walking, jogging, and stair climbing in 44 subjects with unilateral anterior cruciate ligament deficiency and 44 control subjects. Passive knee laxity and isokinetic quadriceps and hamstring muscle strength were also measured. Results Arthrometer measurements did not correlate with peak external flexion or extension moments in any of the activities tested or with isokinetic quadriceps or hamstring muscle strength. Test subjects also had a significantly reduced peak external flexion moment during all three jogging activities and stair climbing compared with the control subjects and this was correlated with significantly reduced quadriceps muscle strength. Conclusions Absolute knee laxity difference did not correlate with dynamic knee function as assessed by gait analysis and should not be used as a sole predictor for the outcome of treatment. Patients with greater than normal strength in the anterior cruciate ligament-deficient limb performed low- and high-stress activities in a more normal fashion than those with normal or less-than-normal strength.

Abstract:

A dimensional analysis was performed to correlate the fuel bed fire rate of spread data previously reported in the literature. Under wind condition, six pertinent dimensionless groups were identified, namely dimensionless fire spread rate, dimensionless fuel particle size, fuel moisture content, dimensionless fuel bed depth or dimensionless fuel loading density, dimensionless wind speed, and angle of inclination of fuel bed. Under no-wind condition, five similar dimensionless groups resulted. Given the uncertainties associated with some of the parameters used to estimate the dimensionless groups, the dimensionless correlations using the resulting dimensionless groups correlate the fire rates of spread reasonably well under wind and no-wind conditions.

Abstract:

The present paper contributes to the analysis and understanding of post-traumatic stress disorder (ptsd) from the perspective of Husserlian phenomenology. The particular approach taken integrates the experience of a ptsd trigger into Husserl’s descriptive framework of noematic constitution. By analyzing the constituent makeup of a particular object that acts as a trigger for ptsd symptoms, a descriptive account of how an ordinary noematic correlate becomes a pathological traumatic correlate is provided. This is done in three steps. First, the traumatic correlate is shown to emerge by way of a judgment. Then, the role of the Ego will be examined to identify the point where the intentional relation between sufferer and traumatic correlate becomes pathological. Third, a phenomenological description of belief characteristics indicates the mechanism by which this pathology is maintained. I conclude by showing the connection between a phenomenological account of ptsd triggers and the current therapeutic practice of prolonged exposure therapy.

Abstract:

Objectives: Numerous studies have identified risk factors which may decrease the chance of successful rotator cuff healing after surgery. Surgeons may also rely on intraoperative tendon quality to predict healing. There is no data that correlates how the gross tendon morphology and the degree of tendonopathy may impact patient outcome or post-operative tendon healing. The purposes of this study were to 1) compare the gross appearance of the supraspinatus tendon during arthroscopic rotator cuff repair with its histological degree of tendonopathy using the Bonar scoring system, and 2) to determine if either histological appearance or gross appearance correlated with Goutallier grade of fatty infiltration, or post-operative repair integrity. Our hypothesis was that there would be a statistical correlation between gross appearance and histological Bonar score, and that gross appearance would correlate with Goutallier grade and rate of healing. Methods: Demographic data from 105 patients undergoing (supraspinatus) rotator cuff repair were obtained. During surgery, the supraspinatus tendon was rated on thickness, fraying, and stiffness. Tendon tissue was also recovered for histological analysis based on the Bonar scoring system. Post-operative ASES and SST scores, as well as ultrasound assessment of healing, were obtained. Statistical analysis based on demographic data was carried out. Correlation between gross appearance of the supraspinatus tendon and rotator cuff histology (Bonar score) was determined. Correlation of gross appearance with Goutallier grade of fatty infiltration, and with post-operative repair integrity was also determined. Results: Gross appearance of torn rotator cuff tendon tissue did not correlate with histological appearance. Neither hisological score nor gross appearance correlated with demographic data, Goutallier grade, or post-operative repair status. Goutallier grade and vascularity were weakly correlated (rho=0.22, p=0.03) Conclusion: The degree of tendonopathy (Bonar Score) did not correlate with morphological appearance of the rotator cuff tendon, and neither of these parameters correlated with rotator cuff healing or patient outcome. Unlike fatty infiltration, or Goutallier scores, which evaluate the degree of muscle disease, this study suggests that the degree of tendonopathy may not be predictive of suboptimal outcomes. In light of these results, abnormal gross tendon appearance should not impact repair effort or technique. [Figure: see text][Figure: see text][Table: see text][Table: see text][Table: see text]

Abstract:

Objectives: We analyzed whether radiographically demonstrated anterior inferior cerebellar artery (AICA) vascular compression of the cochleovestibular nerve in asymmetric hearing loss could be correlated to either the symptomatic ear or to cochlear nerve diameter. Methods: We undertook a retrospective case-control study in which patients were enrolled into a database if audiometry demonstrated asymmetry of 20 dB at one frequency, asymmetry of 10 dB at two frequencies, or a difference of 20% on word recognition scores. If AICA vascular contact was demonstrated on subsequent magnetic resonance imaging of the cerebellopontine angle, patients were included in the study. Patients with vestibular schwannoma or Meniere's disease were excluded. The AICA contact was graded by a blinded neuroradiologist according to criteria proposed by McDermott et al. The cross-sectional area of the cochlear nerve was measured. Results: Symptomatic ears could be correlated to a decreased cochlear nerve diameter, but not to the degree of AICA penetration into the internal auditory canal. Conclusions: AICA vascular compression of the cochleovestibular nerve does not appear to correlate to hearing loss or to cochlear nerve diameter. The finding of decreased cochlear nerve diameter in symptomatic ears implies an alternative mechanism for asymmetric hearing loss.

Abstract:

Data on parasites of rodents, collected over an 18-year period on the Iberian peninsula, were used to find the determinants of parasite species richness. A total of 77 species of helminth parasites (nematodes, cestodes and digeneans) was identified among 16 species of rodents. Parasites were classified into groups according to their specificity towards their host and their life-cycle. A working phylogeny of the rodents was proposed on the basis of molecular and paleontological data and for each host the following parameters were recorded: sample size, weight, geographical range, longevity, and life-style. Two comparative methods were used, the independent comparisons method of Pagel (1992) and the distance matrix method of Legendre, Lapointe & Casgrain (1995). The second method has the advantage of measuring the relative contribution of phylogeny. Both methods gave similar results. Overall parasite species richness correlated only with host sample size. Host body size does not correlate with any subset of parasite species richness. However, host phylogeny is a good predicator of specific parasites and the species richness of digeneans correlates with host geographical range. A phylogenetic reconstruction of host relations was performed using the parasites belonging to subgroups in which richness is correlated with host phylogeny. These parasite species were treated as Dollo characters, i.e. we made the assumption that the loss of a parasite species is irreversible. The consensus tree obtained reflects the major phylogenetic divisions of the host group. Finally, this study illustrates the relative importance of processes acting at different temporal and spatial scales (evolutionary time and actual geographical range of hosts) in determining the structure of helminth parasite fauna.

Abstract:

Objective The dose of neuromuscular blocking drugs is commonly based on body weight, but using muscle mass might be more effective. This study investigated the relationship between the effect of neuromuscular blocking drugs and muscle mass measured using bioelectrical impedance analysis. Methods Patients who were scheduled for elective surgery using a muscle relaxant were screened for inclusion in this study. Under intravenous anaesthesia, 12 mg or 9 mg of rocuronium was administered to males and females, respectively; and the maximal relaxation effect of T1 was measured using a TOF-Watch-SX® acceleromyograph. Results This study enrolled 40 patients; 20 males and 20 females. For both sexes, the maximal relaxation effect of T1 did not correlate with the body weight-based dose of neuromuscular blocking drugs (males, r2 = 0.12; females, r2 = 0.26). Instead, it correlated with the dose based on bioelectrical impedance analysis-measured muscle mass when injected with the same dose of rocuronium (males, r2 = 0.78, female, r2 = 0.82). Conclusions This study showed that the muscle relaxation effect of rocuronium was correlated with muscle mass and did not correlate with body weight when using the same dose. Therefore, a muscle mass-based dose of neuromuscular blocking drugs is recommended.

Abstract:

Clinical studies indicate that bone mineral density correlates with fracture risk at the population level but does not correlate with individual fracture risk well. Current research aims to better understand the failure mechanism of bone and to identify key determinants of bone quality, thus improving fracture risk prediction. To get a better understanding of bone strength, it is important to analyze tissue-level properties not influenced by macro- or microarchitectural factors. The aim of this pilot study was to identify whether and to what extent material properties are correlated with mechanical properties at the tissue level. The influence of macro- or microarchitectural factors was excluded by testing individual trabeculae. Previously reported data of mechanical parameters measured in single trabeculae under tension and bending and its compositional properties measured by Raman spectroscopy was evaluated. Linear and multivariate regressions show that bone matrix quality but not quantity was significantly and independently correlated with the tissue-level ultimate strain and postyield work(r=0.65–0.94). Principal component analysis extracted three independent components explaining 86% of the total variance, representing elastic, yield, and ultimate components according to the included mechanical parameters. Some matrix parameters were both included in the ultimate component, indicating that the variation in ultimate strain and postyield work could be largely explained by Raman-derived compositional parameters.

Abstract:

We investigated whether synchrony between neuronal spike trains is affected by the animal's attentional state. Cross-correlation functions between pairs of spike trains in the second somatosensory cortex (SII) of three macaque monkeys trained to switch attention between a visual task and a tactile task were computed. We previously showed that the majority of recorded neuron pairs (66%) in SII cortex fire synchronously while the animals performed either task and that in a subset of neuron pairs (17%), the degree of synchrony was affected by the animal's attentional state. Of the neuron pairs that showed changes in synchrony with attention, about 80% showed increased synchrony when the animal attended to the tactile stimulus. Here, we show that peak correlation typically occurred at a delay <25 ms; most commonly the delay was close to zero. Half-widths of the correlation peaks were distributed between a few milliseconds and hundreds of milliseconds, with the majority lying <100 ms and the mode of the distribution around 20–30 ms. Maximal change in synchrony occurred mainly during the periods when the stimulus was present, and synchrony usually increased when attention was on the tactile stimulus. If periods of elevated firing rates around the motor response times were removed from the analysis, the percentage of pairs that changed the degree of synchrony with attention more than doubled (from 35 to 72%). The observed effects did not depend on details of the statistical criteria or of the time window used in the analysis.

Abstract:

<p>This paper investigates if farmers’ asset values have a predictive power to asses land quality. A rich sustainable livelihood literature describes small farmers’ biophysical and socio-economic environment through asset values, which closely adheres to the required information for an integrated quality appraisal of the natural resource base. For our analysis we use an in-depth survey held among 50 famers’ households in three rural areas of Senegal. Farmers gave scores for their livelihood assets (human, physical, natural, financial and social) and judgments on the state and trend of the quality of their natural resource base (crop land, rangeland, forest and water resources). As our observational data are dominated by unobserved heterogeneity, we refrain from causal statistical analysis and seek associative patterns between asset values and state and trend of natural resource quality using data visualization techniques and descriptive statistics. We compare categorical data on state and trend of land qualities with asset value classes in a frequency distributions evaluation (Chi-square) and with continuous asset value scores in an analysis of variance (ANOVA). For state of forest we found consistent but counterintuitive differences for various asset values with higher asset values for ‘degraded’ classes and lower values for ‘good’ quality of the forests. There is some evidence that trend of forest quality can be derived from asset value scores which were in agreement with our premise of lower scores for low quality and higher scores for better quality. Yet, overall we have to conclude that asset values do not correlate straightforward and unequivocally with state and trend of natural resource quality. </p>

Abstract:

Temporal analysis of crop development in commercial fields requires tools for large area monitoring, such as remote sensing. This paper describes the temporal evolution of sugar cane biophysical parameters such as total biomass (BMT), yield (TSS), leaf area index (LAI), and number of plants per linear meter (NPM) correlated to Landsat data. During the 2000 and 2001 cropping seasons, a commercial sugarcane field in Araras, São Paulo state, Brazil, planted with the SP80-1842 sugarcane variety in the 4th and 5th cuts, was monitored using nine Landsat images. Spectral data were correlated with agronomic data, obtained simultaneously to the imagery acquisition. Two methodologies were used to collect spectral data from the images: four pixels (2 × 2) window and average of total pixels in the field. Linear and multiple regression analysis was used to study the spectral behavior of the plants and to correlate with agronomic variables (days after harvest-DAC, LAI, NPM, BMT and TSS). No difference was observed between the methodologies to collect spectral data. The best models to describe the spectral crop development in relation to DAC were the quadratic and cubic models. Ratio vegetation index and normalized difference vegetation index demonstrated correlation with DAC, band 3 (B3) was correlated with LAI, and NDVI was well correlated with TSS and BMT. The best fit curves to estimate TSS and BMT presented r² between 0.68 and 0.97, suggesting good potential in using orbital spectral data to monitor sugarcane fields.

Abstract:

AbstractBackground:While echocardiographic parameters are used to quantify ventricular function in infants with single ventricle physiology, there are few data comparing these to invasive measurements. This study correlates echocardiographic measures of diastolic function with ventricular end-diastolic pressure in infants with single ventricle physiology prior to superior cavopulmonary anastomosis.Methods:Data from 173 patients enrolled in the Pediatric Heart Network Infant Single Ventricle enalapril trial were analysed. Those with mixed ventricular types (n = 17) and one outlier (end-diastolic pressure = 32 mmHg) were excluded from the analysis, leaving a total sample size of 155 patients. Echocardiographic measurements were correlated to end-diastolic pressure using Spearman’s test.Results:Median age at echocardiogram was 4.6 (range 2.5–7.4) months. Median ventricular end-diastolic pressure was 7 (range 3–19) mmHg. Median time difference between the echocardiogram and catheterisation was 0 days (range −35 to 59 days). Examining the entire cohort of 155 patients, no echocardiographic diastolic function variable correlated with ventricular end-diastolic pressure. When the analysis was limited to the 86 patients who had similar sedation for both studies, the systolic:diastolic duration ratio had a significant but weak negative correlation with end-diastolic pressure (r = −0.3, p = 0.004). The remaining echocardiographic variables did not correlate with ventricular end-diastolic pressure.Conclusion:In this cohort of infants with single ventricle physiology prior to superior cavopulmonary anastomosis, most conventional echocardiographic measures of diastolic function did not correlate with ventricular end-diastolic pressure at cardiac catheterisation. These limitations should be factored into the interpretation of quantitative echo data in this patient population.

Abstract:

The perceived family environmental factors that could correlate with adolescent suicidal behaviors in the Limpopo Province (South Africa) were investigated. The participants were 435 secondary school adolescents from the Pietersburg area in the Limpopo Province of whom 56% were female, and 44% were male, aged between 15–19 years. A questionnaire was used to determine demographic variables, family environmental factors (Moos & Moos, 1989), and suicidal behaviors. Logistic regression analysis showed that: conflict in a family was a significant correlate for three forms of suicidal behaviors studied; family independence, family cohesion, and family organization were also indicated as significant correlates for suicidal threats, however, family independence and organization correlate negatively with suicidal threat. Mental health workers and educators should consider these findings when planning preventive and therapeutic strategies for the minimization of suicidal behaviors among adolescents in the province.

<p>This study examined the Conscientiousness domain (of the Big-Five Inventory [B5]) and its facets as predictors of Relative Longevity (RL). Its methods of investigation involved the administration of the B5 to a sample of 350 people from Anambra State (of Nigeria, West Africa) who had RL. These participants were drawn from the representative towns of the three senatorial zones in the State. Stratified sampling technique was employed in the selection of the respondents. Pearson Product-Moment Correlation analysis and Multiple Regression analysis were used in data analyses. The results of the research indicated that there was no significant correlation between Conscientiousness domain and RL. However, its (Conscientiousness) facet (of Thorough) correlated significantly with RL. Besides, Conscientiousness did not predict RL, but its facets (Thorough, Reliable, Organized, and Goal-directed) were found to be significant predictors of RL. The study’s conclusion is that although Conscientiousness was neither a correlate nor a predictor of RL among the people of Anambra State, some of its Facets were (correlate and/or predictor/s).</p>

Abstract:

The crack growth behavior in a 304 stainless steel has been investigated at 538°C in air environment. Compact tension specimens were subjected to fatigue, creep and creep-fatigue loading. The combined effects on crack growth rates of load level and hold time have been examined. Stress intensity factors are found to correlate crack growth rates reasonably well for fatigue crack growth. Creep crack growth rates are found to correlate with stress intensity factor and C*(t). Crack growth rates under hold time cycles are successfully correlated with C*(t)avg under various load levels and hold times. Crack growth under creep-fatigue loading has been simulated by elastic-plastic-steady state creep finite element analyses. The results of analysis show that fatigue loading interrupts stress relaxation around the crack tip during hold time and causes stress reinstatement, thereby giving rise to accelerated crack growth compared with crack growth under static loading. Analysis of hold time crack growth based on the cyclic stress-strain response yields crack closure during unloading, and creep deformation during hold time tends to lower the closure load.

Full text

Abstract:

Abstract. While standardization of sampling, processing and picking techniques is essential in micropalaeontology, standard counts (and percentages) have three serious disadvantages. They are interdependent, so changes in one taxon affect counts of all others; they can be misleading, e.g. when percentage abundance increases but absolute numbers decrease; and they conceal changes in absolute abundance, which for palaeoecology are often most revealing. A technique which combines a minimum count with estimates of absolute numbers is recommended and has been applied to 12 samples from a mid-Cenomanian chalk/marl rhythm. Data for insoluble residues, stable isotopes of carbon and oxygen and numbers of planktonic and benthonic foraminifera and ostracods all vary through the rhythm. Absolute abundance of planktonic foraminifera correlates best with surface sea water temperatures calculated from oxygen isotopes. Abundances of both calcareous and agglutinated benthonic foraminifera correlate best with percent insoluble residue values and these foraminifera respond passively to changes in sedimentation rate. Ostracods do not correlate well with either control. Ratios of insoluble residues and of benthonic foraminiferal abundances between chalks and marls confirm that the rhythms are productivity cycles. Mid-Cenomanian chalk beds were deposited rapidly, taking at most 5–7000 years of the 21,000 year precession cycle.

Purpose: To evaluate initial magnetic resonance imaging (MRI) abnormalities in infantile spasms, correlate them to clinical characteristics, and describe repeat imaging findings. Methods: A retrospective review of infantile spasm patients was conducted, classifying abnormal MRI into developmental, acquired, and nonspecific subgroups. Results: MRIs were abnormal in 52 of 71 infantile spasm patients (23 developmental, 23 acquired, and 6 nonspecific) with no correlation to the clinical infantile spasm characteristics. Both developmental and acquired subgroups exhibited cortical gray and/or white matter abnormalities. Additional abnormalities of deep gray structures, brain stem, callosum, and volume loss occurred in the structural acquired subgroup. Repeat MRI showed better definition of the extent of existing malformations. Conclusion: In structural infantile spasms, developmental/acquired subgroups showed differences in pattern of MRI abnormalities but did not correlate with clinical characteristics.

Abstract:

Background:Knowledge of the physical activity correlate profile of adolescent females will provide insight into decreasing physical activity patterns among adolescent females.Methods:Correlates of physical activity and physical activity stage of change were assessed during 2007–2008 among 871 Irish adolescent females in years 1–6 in secondary schools (15.28 ± 1.8 years). Multivariate Analysis of Variance was used to identify whether differences in correlates of physical activity could be detected across year in school and physical activity stages of change.Results:Significant differences (P < .01) were found in 11 of the 16 measured correlates across year in school and in 14 of the 16 correlates across stage of change. Effect size estimates and regression analysis revealed perceived competence, peer social support and intention to be physically active (partial eta range (ηp2) .21–.25) to be the most important predictors of physical activity stage of change.Conclusions:Females in more senior years in school and in earlier physical activity stages of change reported a significantly less positive physical activity correlate profile than females in junior years and in later physical activity stages of change. This finding supports the construct validity of the physical activity stages of change.

Abstract:

Background: Diabetic atherosclerosis is a heterogeneous condition, and that dyslipidemia is only one aspect of the pathophysiology. However, dyslipidemia is the most readily measured and, at the present time, the most readily treated aspect of the problem. The occurrence of dyslipidemia can be reduced by good glycemic control. However poor awareness and other socio-economic factors is a major concern and pose a major hindrance in controlling blood sugar levels. Aims and Objective: This study was conducted to study the dyslipidemia pattern in diabetic patients and its association with other factors. Materials and Methods: The study included 500 subjects and was divided into two groups: Group 1(Diabetic) included 276 patients and Group 2 (Non-diabetic) included 224 patients. The study patients were screened using a pretested structured questionnaire. Fasting plasma glucose and serum lipid profile (cholesterol, TG, HDL) were estimated in automated analyzer (Erba Manheim EM 200). Results: In the current study, all characteristics of diabetes were correlated with each parameter and it was found that disproportionate body mass index, high waist girth was correlated with incidence of dyslipidemia. The education levels and financial background of the subjects were also studied and it was found to correlate well with diabetic dyslipidemia. Conclusion: Early diagnosis and treatment of dyslipidemia in diabetic patients can reduce the morbidity and mortality due to the disease.

Full text

Abstract:

A recent analysis of brain size evolution reconstructed the plesiomorphic brain–body size allometry for the mammalian order Carnivora, providing an important reference frame for comparative analyses of encephalization (brain volume scaled to body mass). I performed phylogenetically corrected regressions to remove the effects of body mass, calculating correlations between residual values of encephalization with basal metabolic rate (BMR) and six life-history variables (gestation time, neonatal mass, weaning time, weaning mass, litter size, litters per year). No significant correlations were recovered between encephalization and any life-history variable or BMR, arguing against hypotheses relating encephalization to maternal energetic investment. However, after correcting for clade-specific adaptations, I recovered significant correlations for several variables, and further analysis revealed a conserved carnivoran reproductive strategy, linking degree of encephalization to the well-documented mammalian life-history trade-off between neonatal mass and litter size. This strategy of fewer, larger offspring correlating with increased encephalization remains intact even after independent changes in encephalization allometries in the evolutionary history of this clade.

Abstract:

Objective Obesity and insulin resistance (IR) predispose to type 2 diabetes mellitus. Yet only half of obese adolescents have IR and far fewer progress to type 2 diabetes mellitus. We hypothesized that amino acid and fatty acid metabolites may serve as biomarkers or determinants of IR in obese teens. Research Design and Methods Fasting blood samples were analyzed by tandem mass spectrometry in 82 obese adolescents. A principal components analysis and multiple linear regression models were used to correlate metabolic components with surrogate measures of IR: homeostasis model assessment index of insulin resistance (HOMA-IR), adiponectin, and triglyceride (TG) to high-density lipoprotein (HDL) ratio. Results Branched-chain amino acid (BCAA) levels and products of BCAA catabolism were higher (P < .01) in males than females with comparable body mass index (BMI) z-score. In multivariate analyses, HOMA-IR in males correlated positively with BMI z-score and a metabolic signature containing BCAA, uric acid, and long-chain acylcarnitines and negatively with byproducts of complete fatty acid oxidation (R2 = 0.659, P < .0001). In contrast, only BMI z-score correlated with HOMA-IR in females. Adiponectin correlated inversely with BCAA and uric acid (R2 = 0.268, P = .0212) in males but not females. TG to HDL ratio correlated with BMI z-score and the BCAA signature in females but not males. Conclusions BCAA levels and byproducts of BCAA catabolism are higher in obese teenage boys than girls of comparable BMI z-score. A metabolic signature comprising BCAA and uric acid correlates positively with HOMA-IR in males and TG to HDL ratio in females and inversely with adiponectin in males but not females. Likewise, byproducts of fatty acid oxidation associate inversely with HOMA-IR in males but not females. Our findings underscore the roles of sex differences in metabolic function and outcomes in pediatric obesity.

Kinematic deviation was summarized using the gait profile score (GPS).Results: Satisfaction levels were generally high (median 80 + /100). Sociodemographic variables did not correlate significantly with any of the satisfaction measures (−0.35 ≤ r ≤ 0.54). Satisfaction correlated strongly with the PEQ scales, particularly ambulation, prosthetic utility, frustration, perceived response and social burden ( r ≥ 0.70). By contrast, the relationships between satisfaction and performance-based outcome measures were not significant (−0.45 ≤ r ≤ 0.43), and the GPS did not correlate with any satisfaction measures (−0.23 ≤ r ≤ 0.15).Conclusions: In this study of high functioning amputees, gait deviation was unimportant to the amputee, while self-reported functional ability and attitudes toward the prosthesis were the strongest correlates of satisfaction following lower-limb amputation.Clinical relevance For the high functioning individuals with lower-limb amputation in this study, gait deviation was not a significant correlate of patient satisfaction. Results suggest that improving self-perceived functional ability and attitudes toward the prosthesis, rather than minimizing gait deviation, will improve patient satisfaction.

Abstract:

Background. The childcare (CC) environment can influence young children’s physical activity (PA), sedentary behavior (SB), and adiposity. The aim of the study was to identify a broad range of CC correlates of PA, SB, and adiposity in a large sample of preschoolers. Methods. 476 preschool children (mean age 3.9 yrs; 47% girls) participated in the Swiss Preschoolers’ Health Study (SPLASHY). PA and SB were measured by accelerometry. Outcome measures included total PA (TPA), moderate-to-vigorous PA (MVPA), SB, body mass index (BMI), and skinfold thickness (SF). PA measures consisted of both daily PA during CC attendance days and overall daily PA (CC and non-CC days). Results. We identified the following CC correlates for higher TPA and/or higher MVPA or lower SB during CC attendance days: older age, sex (boys), more frequent child-initiated interactions during CC, mixing different ages within a group, and the presence of a written PA policy in the CC (all p≤0.02). The CC correlates for overall TPA and/or MVPA or lower overall SB including both CC and non-CC days were the following: older age, sex (boys), more frequent child-initiated interactions during CC, mixing different ages within a group, less parental PA involvement in the CC, and having a larger surface area in CC (all p≤0.046). Correlates for lower SF were sex (boys) and parental PA involvement in the CC (all p≤0.02), and, for lower BMI, only increased age (p=0.001) was a correlate. Conclusions. More frequent child-initiated interactions and mixing different ages in CC, the presence of a written PA policy, and a larger CC surface are correlates of PA and SB during CC attendance days and/or of overall PA. Parental involvement in CC PA projects was a correlate for reduced body fat. These novel factors are mostly modifiable and can be tackled/addressed in future interventions.
