"The influence of some abiotic parameters on growth inclination in ascidian Halocynthia papillosa (Linnaeus, 1767) from the northern Adriatic sea (Croatia)." Archives of Biological Sciences 62, no. 4 (2010): 1007–11. http://dx.doi.org/10.2298/abs1004007s.
Full textAbstract:
This study investigated the relationships between growth orientation, body height and depth on sampling sites. The survey was carried out during 2008 in the area of the island Mali Losinj. A total of 46 specimens of Halocynthia papillosa (Linnaeus, 1767) were analyzed. The growth orientation varied from 60? to 80? and body height was in the range of 20 mm to 110 mm. Pearson?s correlation coefficient shows the positive correlation between growth orientation and body height and the same correlation is determined between depth and body height. The Spearman rank correlation coefficient shows a more positive correlation neither between growth orientation and body height nor growth orientation and depth.

Own measurements examine the tensile strength of expanded polystyrene (EPS) depending on its bulk density. 30 samples were used to calculate the correlation coefficients between these two properties. In addition to the standard Pearson coefficient, we also calculate the rank correlation coefficients, Spearman´s and Kendall´s. By testing the hypotheses, we verify the correlation of the entire population. After finding a relatively close correlation (0.6 - 0.8), we apply different regression models, especially polynomial, but also exponential. We evaluate the properties of parameters in models, their point estimates and confidence intervals. Based on the characteristics of each of the seven regressions, we found the best exponential form of the dependence, before the linear polynomial. The complexity of a mathematical model does not always mean that it is also a more accurate approximation. On the other hand, a simple model makes it possible, in addition to its ease of use, to more closely reflect the examined dependence.

Full textAbstract:
Aim: We aimed to translate, cross-cultural adapt and validate the Marx activity rating scale (MARS) of the knee for Romanian patients with anterior cruciate ligament (ACL) injury. Method: The original English form was translated according to guidelines. We included patients with ACL injury undergoing reconstruction in two centers over 3 years. Subjects completed the translated MARS, International Knee Documentation Committee (IKDC) subjective knee form and EuroQol EQ5D. The examining physician completed the Tegner Lysholm scale as an objective evaluation. Re-testing was obtained after one month. We used Spearman`s correlation to evaluate construct validity and reproducibility, Cronbach’s alpha for internal consistency and intraclass correlation for test-retest reliability. Results: We collected valid forms from 99 patients (32.1 ± 8.8 years, 64.6% males) during the preoperative evaluation and 45 were re-tested. Significant, very good correlations were found between the MARS and Tegner Lysholm (Spearman’s r = 0.712, p < 0.0001) and IKDC (Spearman’s r = 0.801, p < 0.0001). Cronbach’s alpha was 0.893 at the initial completion and 0.799 at re-test. The intraclass correlation coefficient was 0.895. Conclusions: The Romanian-translated MARS is a valid, consistent and reliable physical activity outcome measure in patients with anterior cruciate ligament reconstruction.

Full textAbstract:
Genetic distance among six elite maize inbred lines was analyzed using SSR markers. Hybrid progeny obtained by crossing inbred lines according an incomplete diallel design was tested in field trials together with inbred lines per se.The objective of this study was to determine genetic distance of inbred maize lines and to examine if a significant correlation exist between the genetic distance of parental lines and the exhibited high parent heterosis (HPH) and specific combining abilities (SCA) for grain yield, ear lenght, kernel row numberand number of kernels per row. Twenty one SSR primers were used for genetic assesment of inbreds with detected 92 alleles. Genetically most distant lines were ZPL1 and ZPL5 and ZPL6 with the GD value of 0.549, while the closest one were ZPL2 and ZPL3 with GD value of 0.11. The dendrogram distinguished two main groups of inbreds: ZPL5 and ZPL6 grouped in a smaller cluster and ZPL1, ZPL2, ZPL3 and ZPL4 forming the second cluster. Values of the Spearman?s rank correlation coefficient between genetic distance among inbred lines based on SSR markers and SCA for all analyzed traits were positive and significant with the exception of rows per ear. Highest correlation was exhibited between the genetic distance and SCA for number of kernels per row (0.643). Spearman?s rank correlation coefficient between GD and high parent heterosis was positive and significant for ear length and kernel number in row with coefficient values of 0.554 and 0.611, respectively.

Full textAbstract:
Background/Aim. Quality of life related to health should be seen as a multidimensional concept that, in addition to the physical symptoms associated with a disease and treatment, should include physical, psychological and social functioning of a person. The primary objective of this study was to use the Serbian preliminary version of the Geriatric Oral Health Assessment Index (GOHAI) questionnaire in oder to examine the consistency, reliability and stability, as well as an introduction to the verification tool. Methods. The GOHAI questionnaire with 6-level Likert scale, translated into Serbian, including the relevant oral health characteristics (oral hygiene, required dentures, number of teeth extracted), was filled by five specialists in prosthodontics for 30 randomly selected respondents, before and after the dental prosthetic treatment. Subsequently, in order to measure the reliability of the questionnaire, 27 patients were reinterviewed. Results. The value of Cronbach's Alpha Coefficient (Cr?) before the treatment was 0.878, and after the treatment it was 0.788 confirming the internal consistency and stability of the questionnaire. The validity of discriminatory properties of the GOHAI was confirmed by the Spearman's correlation coefficient (r), which was highly significantly associated with oral health characteristics, confirming the high reliability of the measurement. The results of test-retest analysis measured by the individual Pearson's correlation coefficient (r) were in the range of 0.34-0.97, and for the total score r was 0.927, while the Kappa coefficient was 0.63. The correlation analysis of the GOHAI score before the treatment showed that for 10 questions there was a statistically significant correlation of the score with the answers to the questions, and for 6 questions Spearman?s r was ? 0.7. After the treatment a highly significant correlation of the GOHAI was shown with the answers to 10 questions, while for 5 questions the Spearman?s r was > 0.6. The GOHAI average score before the treatment was 19.44 ? 11.12, and after the treatment 2.77 ? 3.83, where the lower value indicates better quality of life. Conclusion. The results of this pilot study confirm internal consistency and stability of the Serbian preliminary version of the GOHAI questionnaire and the causal relation between the quality of life and the characteristics of oral health of the patients with dentures. Accordingly, instrument verification is recommended.

Full textAbstract:
Introduction: Preoperative evaluation of meningioma consistency is important because it will affect surgical procedures, surgical optimization, risk assessment, and patient management. The consistency of meningioma can be predicted by Apparent Diffusion Coefficient (ADC) value on MRI. ADC values are useful in quantitative tumor assessment based on diffusivity in the tumor. The objective of the study is to find out the correlation between ADC value and the pathology consistency of meningioma.Methods: A retrospective study was carried out using medical records at Dr. Soetomo General Hospital, Surabaya by January 2017 - December 2018. The ADC value was obtained by placing three ROI in the tumor and the consistency was obtained from the results of the pathology examination, followed by the Spearman correlation test.Results: There The tumor range value of ADC was 0.58 x 10-3mm2 s to 1.63 x 10-3mm2/s. The mean ADC value in soft, intermediate, and hard consistency was 1.247+ 0.200 x 10-3mm2/s, 0.950 + 0.453 x 10-3mm2/s, and 0.793 + 0.161 x 10-3mm2/s, the cut-off value of ADC was + 0.822 x 10-3mm2/s with specificity 68% and sensitivity 85%, the AUC is 0.740 with a significance value of 0.0043 (p<α, α = 0.05). It was obtained an ADC correlation with the consistency of meningioma, the significance value is p=0.000 (p<α, α = 0.05).Conclusion: There is a correlation between the ADC value and the consistency of meningioma. The ADC value can be considered for an optimal preoperative evaluation in assessing the consistency of meningioma.

Full textAbstract:
Beijing-Tianjin-Hebei is an area with insufficient per capita water resources. This study evaluates the current status and development trend of sustainable use of water resources in the region, and identifies specific factors influencing sustainable development so as to provide a theoretical basis and data support for the management of water resources in the Beijing-Tianjin-Hebei region. Applying the compound system of social, economic and ecological environment, this study established an evaluation index system. The evaluation index data is obtained through the relevant calculations based on the National Economic and Social Development Announcement, the Water Resources Bulletin and the National Bureau of Statistics data. The index weights are calculated using a combination of rough set and fuzzy theory. The obtained weights were added to the set pair analysis method to acquire evaluation results. Based on the traditional set pair analysis method, this study proposes a new set pair analysis method (Method 4) using S-type functions (Formula (11)) instead of the addition weighted synthesis method (Formula (10)) in the calculation of weighted connections. In order to verify the feasibility of this method, the Spearman correlation coefficient method was used to calculate the correlation coefficient between evaluation results of Method 4 and evaluation results of other traditional methods. In addition, the set pair exponential potential is adopted to determine the impact indicators of the sustainable utilization of water resources in Beijing-Tianjin-Hebei in this study. The results show that in the Beijing-Tianjin-Hebei region, the overall level of sustainable use of water resources has been gradually raised in the past 12 years. The results of the set pair analysis method that cites S-type functions have obtained higher Spearman correlation coefficients than traditional methods. The values of the correlation coefficients are 0.9954, 0.9910, and 0.9928 respectively in Beijing, Tianjin and Hebei. Moreover, according to the results of set pair exponential potential, the indicators in the region are quasi-inverse potential or strong inverse potential, including per capita water resources and the ecological environment water use rate. Thus, a dense population with scarce water resources, and a lack of ecological water are the common problems that Beijing, Tianjin and Hebei have to face.

Full textAbstract:
The research presented in this paper builds on previous work that lead to the definition of a family of semantic relatedness algorithms. These algorithms depend on a semantic graph and on a set of weights assigned to each type of arcs in the graph. The current objective of this research is to automatically tune the weights for a given graph in order to increase the proximity quality. The quality of a semantic relatedness method is usually measured against a benchmark data set. The results produced by a method are compared with those on the benchmark using a nonparametric measure of statistical dependence, such as the Spearman?s rank correlation coefficient. The presented methodology works the other way round and uses this correlation coefficient to tune the proximity weights. The tuning process is controlled by a genetic algorithm using the Spearman?s rank correlation coefficient as fitness function. This algorithm has its own set of parameters which also need to be tuned. Bootstrapping is a statistical method for generating samples that is used in this methodology to enable a large number of repetitions of a genetic algorithm, exploring the results of alternative parameter settings. This approach raises several technical challenges due to its computational complexity. This paper provides details on techniques used to speedup the process. The proposed approach was validated with the WordNet 2.1 and the WordSim-353 data set. Several ranges of parameter values were tested and the obtained results are better than the state of the art methods for computing semantic relatedness using the WordNet 2.1, with the advantage of not requiring any domain knowledge of the semantic graph.

Full textAbstract:
There is considerable debate about the social license to compete with horses and controversy about training methods for dressage horses. The objectives were to: 1. apply the Ridden Horse Pain Ethogram (RHpE) to dressage horses competing at elite Grand Prix level; 2. compare RHpE and judges’ scores; and 3. document deviations in gaits from Fédération Equestre Internationale (FEI) guidelines. Video recordings of 147 competitors from nine World Cup competitions were assessed. Spearman’s rank correlation coefficient tested the correlation between RHpE and judges’ scores. The median RHpE score was 3 (IQR 1, 4; range 0, 7). There was a moderate negative correlation (Spearman rho −0.40, p < 0.001) between the RHpE scores and the judges’ scores. Mouth open with separation of the teeth for ≥10 s (68%), head behind vertical ≥10° ≥10 s (67%), an intense stare for ≥5 s (30%) and repeated tail swishing (29%) were the most frequent RHpE behaviours. Deviations from FEI guidelines were most frequent in passage, piaffe, canter flying-changes, canter pirouettes and “halt-immobility-rein back five steps-collected trot”. In conclusion, most horses appeared to work comfortably for the majority of the test. Further investigation of the influence of a double bridle compared with a snaffle bridle on head position and mouth opening is merited.

Full textAbstract:
Scylla paramamosain is a commercially important species distributed along the coast of southern China and other Indo-Pacific countries. Sudden salinity drop exceeding the adjustment capability of S. paramamosain can result in damage or even mortality. In our previous study, we had analyzed the mechanism of adapting sudden drop in salinity from the level of transcriptomics and proteomics, respectively. This study performed a correlation analysis of RNA sequencing transcriptomics and iTRAQ proteomics in order to investigate the adaptation mechanisms to sudden salinity drop from 23‰ to 3‰. There were 3954 correlations and a total of 15 correlations for differentially expressed proteins (DEPs) and differentially expressed genes (DEGs) from proteomics and transcriptomics. The correlation between DEPs and DEGs was 0, and the Spearman correlation coefficient of the same trend correlation for DEPs and DEGs was the highest, reaching 0.9080. KEGG pathway enrichment correlation revealed that protein digestion and absorption (Ko04974), proximal tubule bicarbonate (Ko04964), and bile secretion (Ko04976) played important roles in Na+/H+ and Na+/K+ exchange. In addition, important genes related to osmoregulation, such as ion transport and carbonic anhydrase, were also detected in the correlation analysis for same trend DEPs_DEGs. In conclusion, the proteome and transcriptome correlation results from this study indicate that ion transport plays a critical role in the adaptation of S. paramamosain to sudden reduction in salinity.

The present research works were conducted to find out the variation in morphological traits and their relationship in Brassica materials at C7 (Colchiploid) alloplasmic populations and F5 generations with respect to their parents. Among the 19 Brassica progeny lines representing the cross products (Brassica napojuncea) of C7 generation of Brassica napus and Brassica juncea (BINA sharisha 5 x Daulot: colchiploid-C7) and F5 generations with their parents, inter-species EG2 (Brassica napus x Brassica juncea) and EG1 (Brassica napus x Brassica juncea) showed better agronomic performance. Phenotypic characters of the genotypes were closely associated with each other for both normal correlation coefficients and Spearmans rank correlation coefficients. The total relative ranking ranged from 1 to 20 and the first rank was estimated for the genotype EG2 genotypes. The last rank was estimated for the genotype ED1 (Brassica napus x Brassica napus). Out of 55 associations, which found in the correlation study, 10 associations were found highly significant at the morphological level. Flower set per plant (self) showed highly significant positive association with total number of siliqua per plant (self) (r = 0.934**) but the significant negative association of the total number of siliqua per plant (self) with siliqua length was very strong (-0.489*). There was a genetic basis of association in most of the cases of pairs of relations. The Spearmans rank correlation test was studied to compare the morphological characterization for distinguishing genotypes. In this present study, this test presented 12 relationships that showed 10 positive significant and two negative significant correlations. In normal correlation coefficients 10 significant associations were found but 12 associations in Spearmans rank correlation. In these techniques, number of flower set per plant (self) had highly significant positive correlation with total number of siliqua per plant (rs = 0.817**). The days to 50 % flowering and number of seed per siliqua (self) had significant negative correlation with number of seed per siliqua (open) (rs = -0.546**) and number of flowers set per plant (open) (rs = -0.563*), respectively. Finally, the study suggested that some yield related traits such as flower set per plant, number of siliqua per plant, seed per siliqua and days to 50% flowering can be selected and used in breeding program for future increasing the grain yield of rapeseed.

The purpose of this study was to adapt the Spitzer Quality of Life Index and evaluate its reliability in patients with low back pain. The following steps were followed: translation, back-translation, evaluation by a committee, and pretest. The reliability was estimated through stability and homogeneity assessment. The validity was tested comparing scores of the Spitzer (QLI) with the SF-36 and the Roland-Morris. The psychometric properties were evaluated by the self-application on 120 patients. Results showed that the Cronbach's Alpha was 0.77. Intraclass correlation coefficient for test-retest reliability was 0.960 (p<0.001; IC95%: 0.943; 0.972). Spearman´s correlation coefficient for test-retest reliability was 0.937 (p<0.001). There was significant correlation between the Spitzer (QLI) scores and the dimensions of the SF-36. A significant negative correlation was found between the Spitzer (QLI) and the Roland-Morris scores (r = - 0.730). The adaptation process was conducted successfully and the questionnaire presented reliable psychometric measures.

Purpose An electrochemical method based on the open circuit potential (OCP) fluctuations was put forward. It can be used to optimize the alloy compositions for improving the corrosion resistance of rust layer. Design/methodology/approach The potential trends and potential fluctuations of carbon steels in seawater were separated by Hodrick–Prescott filter. The Spearman correlation coefficient and max information coefficient were used to explore the correlation of alloy compositions and potential fluctuations. Findings After long-term immersion, potential fluctuation resistance (PFR) can be used to characterize the corrosion resistance of metals and its rust layers. In the 1,500 to 2,500 h exposure period, Fe, C and S compositions have strong negative correlations, whereas PFR and P composition have weak negative correlations. Mn, Cu and Ti alloy compositions help the rust layer of carbon steels have higher PFRs. These elements that exhibit higher PFRs in this period have been confirmed to have the effect on improving the corrosion resistance of rust layer. Originality/value A new computing method for alloy composition optimization of carbon steels based on the OCP fluctuations was put forward. This method combines electrochemical monitoring with the long-term actual seawater environmental tests of various carbon steels.

Context: Predicting when an athlete can return to sport after muscle injury is a major concern. Objective: To determine whether combining objective clinical and ultrasound findings at presentation accurately predicted time to sport resumption in athletes with muscle injuries. Design: Cohort study. Setting: Sports medicine clinic. Patients or Other Participants: A total of 93 consecutive patients, 87 male and 6 female, were seen over a 1-year period for sudden-onset muscle pain while engaging in a sporting activity within the last 5 days and inability to continue the training session or game. Intervention(s): Standardized physical examination and sonogram. Main Outcome Measure(s): Statistical associations between clinical and sonographic features at presentation and time to sport resumption (<40 days or ≥40 days) were evaluated using multivariate models. Correlations between time to sport resumption predicted by a sports medicine specialist and actual time to sport resumption were evaluated using the Spearman rank correlation coefficient. Results: The 93 patients had 95 injuries, caused by muscle contraction in 86 cases and impact in 9 cases. Only 7 injuries had normal sonogram findings. Late sport resumption was associated with 4 clinical criteria (bruising, tenderness to palpation, range-of-motion limitation compared with the other limb, and increased pain with isometric contraction during passive limb straightening) and 4 sonographic criteria (disorganized fibrous tissue, intramuscular hematoma, intermuscular hematoma, and power Doppler signal). The Spearman rank correlation coefficient between predicted and actual times was 0.669 (P < .0001) for mild exercise resumption and 0.804 (P < .0001) for full sport resumption. Conclusion: A combination of physical and sonographic data collected during the acute phase of sport-related muscle injury was effective in predicting time to sport resumption.

Abstract Molecular profiling strategies generally apply either transcriptomic or proteomic technologies for dissection of aberrant expression patterns between normal and diseased samples. Although studies in yeast (S. cerevisiae) demonstrate excellent concordance between gene/protein abundance, the lack of integrated comparisons using human systems prompted us to stringently dissect these relationships in a cellular model system (platelets) devoid of active transcriptional activity. Highly-purified platelets from four healthy donors were pooled for proteomic analyses which were completed in duplicate using tryptic digestion of 100 mg cytoplasmic fractions, followed by cation exchange liquid chromatography coupled to tandem mass spectrometry (μLC-MS/MS). Spectral (peptide) counts were used as a semi-quantitative means of establishing protein abundance among normalized MS data sets, with excellent concordance between platelet runs (Spearman rank correlation r = 0.87, p <0.0001). Microarray data derived from five platelet apheresis donors were hybridized to the Affymetrix HU133a gene chip, and relative transcript abundance established by rank-ordering the unique, normalized set of non-redundant mRNAs (N=1240). Two comprehensive bioinformatics approaches using either platelet-restricted or genome-wide relational databases were additive in identifying 690 unique platelet proteins, representing increase of 230% or 131% to either approach alone. Of the identified proteins, 72% had a corresponding mRNA transcript, although a smaller fraction of mRNAs (41%) had a corresponding protein. The calculated codon adaptation index (CAI) for the 156 highest- and the 156 lowest-expressed platelet transcripts predicted strong correlation to protein abundance. Spearman correlations on data rank-ordered by either protein or transcript abundance demonstrated a maximal correlation coefficient of 0.44 (p =0.034) for an 18-member protein subset (higher protein abundance), although the 20 most abundant platelet transcripts had an overall correlation that was considerably higher (r =0.84, p <0.0001). Thus, the most highly expressed platelet transcripts are powerful predictors for the corresponding protein abundance. More detailed gene/protein abundance comparisons were completed from a uniquely-created relational database containing quantitative profiles specifically linked to RefSeq accession numbers. While the range of molecular weights (5.1–280 kDa) and predicted tryptic fragments (9–326) for these gene/protein pairs were quite broad, there was a direct linear correlation using in silico mathematical models (Pearson correlation r =0.96, p <0.0001). Interestingly, both Pearson and Spearman correlation coefficients were low in the absence of tryptic correction, although they became statistically-significant after tryptic normalization (Pearson correlation r = 0.31, p = 0.019; Spearman correlation r = 0.27, p = 0.0014). In summary, these data establish that an integrated analytical platform incorporating both transcriptomic and proteomic databases considerably enhances efficiency of platelet protein detection, and when analyzed using highly-rigorous and novel methods that normalize for tryptic fragment number, there is significant correlation between gene/protein abundance, unrelated to ongoing transcriptional activity.

Abstract Objectives The aim of the study was to analyze the correlation between periodontitis severity in systemic lupus erythematosus (SLE) with CD4/CD8 lymphocytes ratio and cytomegalovirus gamma immunoglobulin (IgG CMV) level. Materials and Methods This is a descriptive study using a cross-sectional approach that included 93 subjects who were diagnosed with SLE in Rheumatology Department, Saiful Anwar Hospital, during 2017 to 2019. Periodontitis severity was assessed by periodontal Index (PI). CD4/CD8 lymphocyte ratio was determined using flow cytometry and IgG CMV levels using enzyme-linked immunosorbent assay. Statistical Analysis The differences among the three groups were analyzed using analysis of variance. Correlation among the groups was calculated using Spearman/Pearson correlation coefficient test, while regression analysis was done using Statistical Package for the Social Sciences. Results The mean of periodontitis severity and standard deviation in SLE was 2.66 ± 1.02. There were negative correlation between CD4/CD8 lymphocyte ratio with periodontal index (r = –0.971) and positive correlation between IgG CMV level with periodontal index (r = 0.977). Conclusions Inverted CD4/CD8 ratio and IgG CMV were found associated with periodontitis severity in SLE patient. Further research was recomended that CD4/CD8 lymphocytes ratio and IgG CMV can be used as a potensial marker of periodontitis severity in SLE patients.

This article deals with comparison of the behaviour of spruce wood and polyolefins (polyethylene PE and polypropylene PP) during the test on the cone calorimeter. Samples were tested on the cone calorimeter at heat flux of 20 and 40 kW/m2. An evaluation of the behaviour of examined materials was based on the determination of the maximum and the average heat release rate, yield of carbon monoxide (CO), and relative comparison of tendency to fire propagation in a flashover phase. The tendency of materials to fire propagation in the flashover phase was evaluated based on the Pearson ́s correlation, the Spearman ́s correlation and the Kendall ́s correlation coefficient of HRR-CO and CO2-CO. Spruce wood showed better properties in comparison with PE and PP in all evaluated parameters (the maximum and the average heat release rate, the yield of CO, and also the resistance to fire propagation in the flashover phase. Additionally, spruce wood showed significantly lower sensitivity of dependence of the maximum and also the average heat release rate on external heat flux.

Full textAbstract:
Purpose. To investigate the value of intravoxel incoherent motion (IVIM) magnetic resonance imaging in the evaluation of the osteosarcoma (OS) response to preoperative neoadjuvant chemotherapy (NAC) in teens. Methods. Eighteen consecutive osteosarcoma patients (12 males and 6 females) diagnosed by histopathology were enrolled. All enrolled patients received NAC and underwent MRI examinations before and after 2 cycles of NAC. The volume (V), apparent diffusion coefficient (ADC), (slow) diffusion coefficient (D), pseudo-perfusion (fast) diffusion coefficient (D⁎or D star), and perfusion fractions (f) of the OS before and after NAC were measured and analysed. The sensitivity and the specificity of the ADC, D, D⁎ and f values and the correlation between changes in volume (ΔV) and the IVIM-derived parameters (ΔADC, ΔD, ΔD⁎ and Δf) were also calculated and analysed. Paired Student’s t-tests, receiver operating characteristic (ROC) curves, and Spearman correlation analyses were used. Results. The mean volume of the OS after NAC decreased significantly (61.55±9.3 cm3 vs 40.26±4.1 cm3) (P<0.05). After NAC, the ADC (1.21±0.09 × 10-3 mm2/s vs 1.73±0.11 × 10-3 mm2/s) and D (1.14±0.09 × 10-3 mm2/s vs 1.63±0.1 × 10-3 mm2/s) values increased and f (28.58±1.37% vs 20.93±1.16%) values decreased significantly (P<0.05), while D⁎ (9.17±0.98 × 10-3 mm2/s vs 8.94±0.13 × 10-3 mm2/s) values changed slightly (P>0.05). The AUC values of ADC (0.938) and D (0.943) were higher than those of D⁎ (0.574) and f (0.765). The sensitivity and specificity of ADC (0.778, 1) and D (0.944, 0.833) values were superior to those of D⁎ (0.278, 0.722) and f (0.5, 0.944) values. No significant correlations were found between the ΔV and ΔADC, ΔD, ΔD⁎ and Δf values (P>0.05). Conclusion. IVIM-derived parameters ADC and D have the potential to be imaging biomarkers for evaluation of the therapeutic response to NAC in OS patients.

Full textAbstract:
PM2.5 severely affects human health. Remotely sensed (RS) data can be used to estimate PM2.5 concentrations and population exposure, and therefore to explain acute respiratory disorders. However, available global PM2.5 concentration forecast products derived from models assimilating RS data have not yet been exploited to generate early alerts for respiratory problems in Brazil. We investigated the feasibility of building such an early warning system. For this, PM2.5 concentrations on a 4-day horizon forecast were provided by the Copernicus Atmosphere Monitoring Service (CAMS) and compared with the number of severe acute respiratory disease (SARD) cases. Confounding effects of the meteorological conditions were considered by selecting the best linear regression models in terms of Akaike Information Criterion (AIC), with meteorological features and their two-way interactions as explanatory variables and PM2.5 concentrations and SARD cases, taken separately, as response variables. Pearson and Spearman correlation coefficients were then computed between the residuals of the models for PM2.5 concentration and SARD cases. The results show a clear tendency to positive correlations between PM2.5 and SARD in all regions of Brazil but the South one, with Spearman’s correlation coefficient reaching 0.52 (p < 0.01). Positive significant correlations were also found in the South region by previously correcting the effects of viral infections on the SARD case dynamics. The possibility of using CAMS global PM2.5 concentration forecast products to build an early warning system for pollution-related effects on human health in Brazil was therefore established. Further investigations should be performed to determine alert threshold(s) and possibly build combined risk indicators involving other risk factors for human respiratory diseases. This is of particular interest in Brazil, where the COVID-19 pandemic and biomass burning are occurring concomitantly, to help minimize the effects of PM emissions and implement mitigation actions within populations.

ABSTRACT Introduction: Self-perception of dietary quality has been associated with weight and body composition, as well as dietary pattern. Both the gain and maintenance over the long term of excess weight have been frequently associated to dietary and life habits of individuals, which justifies the improvement of assessment methods. Methods: Convenience sample consisting of 14 women who took classes at Contours® gym, aged 18-45 years. Data collection was performed in two stages: the first consisted in the application of questionnaires designed specifically for the research on socioeconomic data, general information on health and the regular use of drugs, self-perception of dietary habits and a 24-hour recall. In the second stage, collection of the 24-hour diet recall was performed. The Revised Diet Quality Index (RDQ-I) was used in the assessment of dietary standards. Results: In the assessment of eating habits, 85.7% of the respondents were classified as healthy. Most of them, 78.57%, rated their dietary pattern as positive, 14.3% were not able to rate it and 7.13% rated it negatively. The Spearman correlation coefficient indicated that there was a moderate positive correlation between the RDQ-I (Revised Diet Quality Index) and self-perception. Conclusions: There is a statistical significant correlation of dietary pattern and dietary quality.

Full textAbstract:
Knowledge of the effects of introgressing temperate maize germplasm in tropical elite inbred lines on genetic variation and relationship between grain yield and its components is limited. In this study, the objective was to evaluate introgressed maize inbred lines for selected economic traits. Field evaluation was carried out on 122 inbred lines comprising sets of introgressed lines from three selection environments, parental inbred lines and two common checks. Genetic variation was significant (P < 0.05) for all the major economic traits among inbred lines within and across sets. Heritability estimates ranged from low (0.21%) to high (91%) for stalk lodging and silking days, respectively. Comparison of means of inbred lines sets illustrated that environmental effect had influence on grain yield of introgressed lines. Grain yield and ear prolificacy performance across sets also illustrated that introgression of temperate germplasm in tropical elite inbred lines was effective. Spearman’s rank correlation analysis on grain yield and ear prolificacy highlighted correlation between selection environments. Correlation among traits demonstrated that grain yield had significant (P < 0.05) positive correlation with plant and ear aspects, plant height, root and stalk lodging, ear prolificacy and grain moisture content at harvest. Further, decomposing of correlation using path coefficient analysis showed significant (P < 0.05), and moderate direct effects of ear prolificacy and plant height on grain yield; indicating that these traits had the highest contribution towards grain yield. Generally indirect effects of secondary traits on grain yield potential of inbred lines was negligible. Therefore, direct selection of plant height and ear prolificacy will be emphasised during introgression of temperate germplasm in tropical elite inbred lines.

Context Rotator cuff weakness and rotation ratio imbalances are possible risk factors for shoulder injury among overhead athletes. In consensus statements, organizations have highlighted the importance of a screening examination to identify athletes at risk of injury. The screening should be portable and designed to be feasible in many different environments and contexts. Objective To evaluate the reliability and validity of the Self-Assessment Corner (SAC) for self-assessing shoulder isometric rotational strength and examining whether performance on 2 physical performance tests was correlated with isometric shoulder rotational strength using the SAC in handball players. Design Cross-sectional study. Setting Sport setting. Patients or Other Participants A first sample of 42 participants (18 men, 24 women) was recruited to determine the reliability and validity of the SAC. In a second sample of 34 handball players (18 men, 16 women), we examined correlations between physical performance tests and the SAC. Main Outcome Measure(s) The SAC was used to measure isometric rotational strength with the upper extremity at 90° of abduction in the frontal plane and 90° of external rotation and the elbow flexed to 90° with neutral rotation of the forearm. The SAC findings were compared with those from manual testing. Results from the seated medicine ball throw (SMBT) and closed kinetic chain upper extremity stability test (CKCUEST) were used to establish relationships with the SAC. We calculated intraclass correlation coefficients to determine relative reliability and used standard error of measurement and minimal detectable change to quantify absolute reliability. Relationships among the different strength-testing procedures and with the physical performance tests were determined using the Pearson product moment correlation coefficient (r) or Spearman rank correlation coefficient (rs). Results We observed good to excellent reliability (intraclass correlation coefficient [2,k] range = 0.89 to 0.92). The standard error of measurement varied from 3.45 to 3.48 N. The minimal detectable change with 95% confidence intervals ranged from 8.06 to 8.13 N. Strong correlations were present among strength procedures (r = 0.824, rs range = 0.754–0.816). We observed moderate to strong correlations between the CKCUEST findings and rotational strength (r range = 0.570–0.767). Moderate correlations were found between rotational strength and SMBT (r range = 0.573–0.626). Conclusions The SAC is a clinically applicable and standardized protocol for self-assessing rotational strength in young healthy adults without pathologic conditions. Performance on the SMBT and CKCUEST may be valuable as a screening tool to further assess shoulder strength.

Introduction: Psoriasis is a chronic skin disease characterized by scaly patches affecting approximately 2-5% of the population. The disease has a negative impact on quality of life and, therefore, psoriatic patients often develop depression. Our work deals with quality of life and depression in psoriasis sufferrers and strives to determine the correlation between their quality of life and depression. Methods: The research took place in the University Hospital Olomouc in 2017 and used questionnaires WHOQOL-BREF and BDI-II. 50 patients with psoriasis were chosen randomly. To process the data we used Mann-Whitney test (the level of significance = 5%) and Spearman´s correlation coefficient (the level of significance = 1%). Results: The results proved that psoriasis has a significant impact on quality of life. The scores for the overall life quality as well as for individual domains were significantly lower in psoriatic patients than in the control group (p<0.001). The degree of depression in patients with psoriasis showed statistically significant correlation in all domains of the quality of life. We proved negative correlation in the overall quality of life (rs =- 0.691**), physical condition (rs =-0.499**), social relations (rs =-0.546**), overall health (rs =-0.396**), and environment (rs =-0.386**). Conclusion: With regard to the ascertained negative correlation between psoriasis and depression and lower quality of life of the sufferers compared to the healthy population, it is essential for healthcare professionals to pay attention not only to somatic manifestations of the disease but also to the patients´ mental health.

Backgraund/Aim. The Thyroid Specific Patient Reported Outcome Measure (ThyPRO) questionnaire is self-administered and intended to measure quality of life of thyroid patients. The aim of this study was to investigate the validity and reliability of the translated new, ThyPRO questionnaire in Serbian patients with thyroid disease. Methods. The translation process followed an internationally accepted methodology. The questionnaire was validated in 100 consecutive thyroid patients hospitalized in a tertiary level hospital, between April and August 2012. Internal reliabilities of ThyPRO scales were assesessed using Cronbach?s ? coefficient. Association between age, gender, education, marital and employment status, place of living, diagnosis, current treatment, hormonal status and patient quality of life were determined using Pearson?s (r) and Spearman?s (q) correlation coefficients. Results. Internal consistency and reliability for ThyPRO scales were satisfactory. Cronbach?s ? coefficients of 13 multi-item scales of the ThyPRO were > 0.83 (range 0.83-0.95). The scores, obtained by this questionnaire, correlated significantly with patients gender, employment status, diagnosis, current treatment and place of living. A highly significant inverse relationship was found between scores and hormonal status as well as between scores and disease duration. Patients? age, marital status and thyroid-stimulating hormone level did not influence any scale score. Conclusion. The ThyPRO may be useful in measuring health-related quality of life in patients with thyroid disease in Serbia.

This study examines the relationship between Cat Bonds market and the other financial markets. Precisely, cointegration tests (the Engle and Granger’s methodology) were applied on weekly data of five indexes over the period 2012- 2019 to test for the existence of a long-run dynamic equilibrium relationship between Cat Bonds market and four financial markets, namely, Insurance Linked Securities (ILS) market, S&P 500 (first stock market), MSCI (second stock market) and Corporate Bonds market. In addition, a comparative analysis correlation vs cointegration was conducted to verify whether Cat Bonds can be really considered as zero-beta assets in the short-run (correlation) as well as the long-run (cointegration). For correlation analysis we employed three correlation coefficients (Pearson’s Correlation Coefficient, Spearman’s Rank Correlation Coefficient and Kendall's Rank Correlation Coefficient). Overall, the main findings of this study showed that in the short-run, Cat Bonds are partially zero-beta assets while over the long-run they are entirely zero-beta assets. Such results will be of great importance for investors in their decision choice between a short strategy or a long strategy in Cat Bonds’ investing.

Abstract Introduction Facial nerve palsy results in both functional disability and psychological morbidity. There are several well-established grading scales to quantify the quality of life of these patients. Objective Translate and validate the Facial Clinimetric Evaluation (FaCE) scale and Synkinesis Assessment Questionnaire (SAQ) to Brazilian Portuguese. Methods This study adopted a forward-backward translation method and performed cross-cultural adaptation. A pilot study was conducted to correct any confusing language and to evaluate content validity. A validation study was then performed. Internal consistency of the Brazilian Portuguese version of the FaCE and SAQ items was evaluated by Cronbach’s alpha coefficient. Construct validity was assessed by Spearman’s Rank Correlation Coefficient between FaCE and SAQ scores to eFACE, House-Brackmann, Short Form 12 (SF-12) and Facial Disability Index (FDI) (sub)scores. Results A total of 90 patients were included. Cronbach’s alpha for total domain scored 0.881 for FaCE and 0.809 for SAQ. FaCE total score correlation to eFACE total and House-Brackmann showed Spearman’s r value of 0.537 and −0.538, respectively (p < 0.001). SAQ correlation to eFACE synkinesis subdomain was −0.449 (p < 0.001). No correlation was found between SAQ and HB score. FaCE total score correlations were of 0.301 and 0.547 for SF-12 PCS and MCS, respectively (p < 0.001). Correlation between FaCE total and FDI Physical and Social/well-being functions were 0.498 and 0.567 (p < 0.001). Conclusion Brazilian Portuguese FaCE scale and SAQ versions achieved high validity and reliability in the present study. These translated instruments demonstrated good psychometric properties, being proper to use in clinical practice in Brazil and with Brazilian Portuguese speakers.

Introduction/Objective. Dental patient-reported outcome measures are very important in a diseasespecific population such as edentulous subjects. The aim of the study was to adapt the Oral Health Impact Profile for Edentulous Subjects (OHIP-EDENT) in the cultural environment of North Macedonia. Methods. This study adapted the original 19-item version of the OHIP-EDENT. After the forward?backward translation according to international standards, the OHIP-EDENT-MAC was psychometrically tested in 109 complete denture wearers. Results. The Cronbach?s ? coefficient of 0.892 confirmed good internal consistency. Test?retest reliability was confirmed by high intraclass correlation coefficient of the summary scores (0.986; 95% confidence interval 0.968?0.993). The concurrent validity was confirmed by the Spearman?s rank correlation coefficient (r = -0.654) between the OHIP-EDENT-MAC summary scores and a single question which rated satisfaction with the existing removable dentures using a five-point scale (1 = unsatisfied, 5 = completely satisfied). Construct validity was confirmed by exploratory factor analysis. All item loadings were above 0.4. Items grouped in four factors (dimensions), which explained 66.25% of the variance, in both non-rotated and rotated matrices. Good responsiveness was confirmed in 33 participants after complete denture relining. Their OHIP Summary score (33.09 ?} 11.61) decreased significantly (t = 7.68; df = 32; p < 0.001) after treatment (24.39 ?} 8). The standardized effect size was 0.75, representing moderate to large effect. Conclusion. The OHIP-EDENT-MAC showed satisfactory psychometric properties providing evidence for its use in edentulous population of North Macedonia.

This study aimed to assess generic health-related quality of life (HRQoL), pain intensity, and anxiety levels and the relationship between the three aspects in healthy young Chinese orthodontic patients in the early stage of orthodontic treatment. We enrolled 252 eligible participants (10–29 years old) to complete validated Chinese versions of questionnaires, including the State-Trait Anxiety Inventory (S-AI), the visual analogue scale (VAS), and the Short-Form 36-Item Health Survey (SF-36) at baseline and on days 1, 2, 3, 7, 14, and 30 after initial archwire placement (SF-36 only at baseline and day 30). The response rate was 96% (243 of 252). SF-36 had moderate reliability (Cronbach's alpha coefficient exceeding 0.7, good fit on day 30). Statistical significant changes were observed in physical function (P<0.01), body pain (P=0.01), and general health (P<0.01) domains. Spearman correlation coefficients for SF-36 with S-AI were −0.131~−0.515 (P<0.05); SF-36 with VAS were −0.141~−0.273 (P<0.05), indicating significant but moderate negative correlations between HRQoL and pain/anxiety. Overall, the application of SF-36 in assessing HRQoL is reluctantly suitable for young Chinese orthodontic patients in the early stage of orthodontic treatment. Early treatment-related pain and anxiety are important factors in HRQoL.

AbstractThe aim is to assess the association between computed tomography (CT) findings and clinical outcomes in posterior tibial plateau fractures (TPF). This is a retrospective analysis of the records of 23 patients with posterior TPF treated at our institution between 2004 and 2011. Two indices of residual articular displacement of posterior TPF (gap and step-off) were measured from CT images, and clinical outcomes were assessed using the Short Musculoskeletal Function Assessment (SMFA) questionnaire. Spearman's rank correlation coefficient analysis was used to evaluate the correlations between the postoperative posterior TPF radiological findings and the clinical outcomes. Both the intraobserver and the interobserver correlation coefficients were high (0.90 and 0.92, respectively), indicating excellent agreement between the reviewers for the assessment of residual displacement via CT scans. Additionally, residual articular step displacement showed a strongly negative correlation with clinical outcomes (R = 0.700, p = 0.036), whereas the residual gap displacement did not (R = 0.400, p = 0.505). More importantly, the medial posterior step displacement was significantly correlated with the clinical outcomes (p = 0.040), whereas the lateral posterior step displacement was not (p = 0.618). Based on the data of this study, the higher the step-off deformity of the medial posterior tibial plateau, the worse the SMFA. More attention should be paid to this factor when treating medial posterior TPF.

La motivación puede ser considerada una de las temáticas más estudiadas en el contexto deportivo, principalmente por su relación con la intención futura de práctica y la satisfacción de los atletas. En busca de comprender mejor este fenómeno, este estudio verificó la correlación entre la motivación autodeterminada y diferentes constructos psicológicos en atletas de baloncesto femenino escolar. Como instrumentos se utilizaron: 1) Cuestionario Sociodemográfico; 2) Cuestionario de Motivación en el Deporte (SMS); 3) Cuestionario de Comportamientos parentales en el deporte (QCPD); 4) Escala de Autonomía Percibida en el Deporte; 5) Escala de Competencia Percibida en el Deporte; 6) Escala de Necesidad de Relación; 7) Escala de autodescripción (autoestima); 8) Escala de Satisfacción con la Vida; 9) Escala Breve de Resiliencia (BRS). Para el tratamiento de los datos se utilizó el paquete estadístico SPSS en la versión 21.0 para Windows, y se adoptó un nivel de significancia de p <0,05. Se realizaron las estadísticas descriptivas, media (M) y desviación estándar (DP). El análisis de la simetría de la distribución de las frecuencias (normalidad) fue efectuada mediante la utilización del test Shapiro-Wilk. Para conocer la asociación lineal (relación) entre diferentes variables, se calculó el coeficiente de correlación de Pearson para los datos que presentaron simetría y el coeficiente de correlación de Spearman para los datos que no presentaron simetría. Los datos presentaron correlaciones significativas entre la motivación y el comportamiento parental; entre la motivación y las necesidades de autonomía y competencia; y motivación con la autoestima. Se sugiere atención especial al comportamiento de los padres y profesores, en relación a la conducta en esta importante fase de desarrollo físico, social y deportivo. Motivation can be considered as one of the subjects most studied in the sportive context, mainly because of its relationship with the intention of further practice and with the athlete´s satisfaction. In order to better understand this phenomenon, this study assessed the correlation between the self-determined motivation and various types of psychological constructs in women´s basketball athletes in the school.
The following tools were used: 1) Sociodemographic questionnaire; 2) Motivation in Sports questionnaire (SMS); 3) Parental Behavior in Sports questionnaire (QCPD); 4) Scale of Perceived Autonomy in Sports; 5) Scale of Perceived Skill in Sports; 6) Scale of Need of Relationship; 7) Scale of self-description (self-esteem); 8) Scale of Satisfaction with Life; 9) Brief Resilience Scale (BRS). Data treatment used the SPSS statistical package, version 21.0 for Windows, with a significance level of p<0,05. Descriptive statistics, average (M) and standard deviation (DP) were also used.
The analysis of the symmetry of the distribution of frequencies (normality) was done using the Shapiro-Wilk test. To know the linear association (relationship) between different variables, the Pearson´s correlation coefficient was calculated for symmetric data and Spearman´s correlation coefficient for non-symmetrical data. The results showed significant correlations between motivation and parental behavior, motivation, and need for autonomy and skill, and motivation and self-esteem.

Abstract: Introduction: Hand and wrist bone age assessment methods cannot be performed when using the recommended patient position within the EOS scanner. Aim: We aimed to assess alternative methods for use with the EOS. Method: After investigating 9 alternatives, five methods were selected – cervical vertebra (Hassel–Farman), iliac crest (Risser ‘plus’), hip (Oxford), knee (O’Connor), calcaneus (Nicholson) – and applied to EOS scans of 114, 2–21-year-old normal individuals. Intraclass correlation coefficient tests for reliability and Spearman correlation with calendar age were assessed. Results: Intra- and interobserver reliabilities were all excellent, except with the knee method (0.865 – ‘good’). Calcaneal and cervical methods were the fastest to apply (mean 17.5 s, 33.4 s per evaluation), however, calcanei were unassessable in 14% of scans (versus 1% of cervical). All methods correlated significantly with calendar age (r>0.829, p<0.05). Difficulties were principally absent (12%) or obscured (23%) landmarks. Conclusion: Bone age assessment is possible with all 5 methods, however, the Hassel–Farman method proved to be easily useable, fast and reliable. Orv Hetil. 2019; 160(16): 619–628.

AbstractThe present study assessed the correlations between cerebral regional saturation detected by near infrared spectroscopy (NIRS) and cardiac index (CI) measured by pulmonary artery catheter. This was a retrospective cohort study conducted in the cardiac intensive care unit in a tertiary care children's hospital. Patients younger than 18 years of age who underwent heart transplantation and had a pulmonary artery catheter on admission to the pediatric cardiac intensive care unit between January, 2010, and August, 2013, were included. There were no interventions. A total of 10 patients were included with median age of 14 years (range, 7–17). Indications for transplantation were dilated cardiomyopathy (n = 9) and restrictive cardiomyopathy (n = 1). Mixed venous oxygen saturation (SvO2), cerebral regional tissue saturation (rSO2), and CI were recorded hourly for 8 to 92 hours post-transplantation. Spearman's rank correlation coefficient was used to assess correlations between SvO2 and cerebral rSO2 and between CI and cerebral rSO2. A total of 410 data points were collected. Median, 25th and 75th percentiles of cerebral rSO2, CI, and SvO2 were 65% (54–69), 2.9 L/min/m2 (2.2–4.0), and 75% (69–79), respectively. The correlation coefficient between cerebral rSO2 and CI was 0.104 (p = 0.034) and that for cerebral rSO2 and SvO2 was 0.11 (p = 0.029). The correlations between cerebral rSO2 and CI and between cerebral rSO2 and SvO2 were weak. Cerebral rSO2 as detected by NIRS may not be an accurate indicator of CI in critically ill patients.

AbstractObjectivesAccording to a recent study, ratings on the Psychotic Depression Assessment Scale (PDAS) obtained via a dedicated semi-structured interview are valid measures of the severity of psychotic depression. This study aimed to further test the validity, scalability and responsiveness of the PDAS in older adults using independent ratings on the Clinical Global Impression Scale – Severity (CGI-S) and the Montgomery-Asberg Depression Rating Scale (MADRS) as references.MethodsRatings were performed at admission and discharge at two old age psychiatric wards in Flanders, Belgium. In total, 62 older adults (mean age: 74.3 years) with psychotic depression were included. The PDAS was rated by trained nurses using the semi-structured PDAS interview. Senior psychiatrists scored the participants on the CGI-S. Psychologists or experienced nurses rated participants on the MADRS. Clinical validity was assessed by correlating the PDAS total scores with CGI-S ratings and MADRS total scores. Mokken analysis was performed to assess the scalability of the PDAS. Responsiveness was assessed by comparing the proportion of participants in remission (PDAS total score <8 at study baseline and endpoint).ResultsThe Spearman correlation coefficients were 0.76 and 0.79 for the PDAS versus CGI-S and PDAS versus MADRS, respectively. The Mokken analysis yielded a Loevinger coefficient of 0.46, which is indicative of scalability. At admission, no participants met the PDAS remission criterion. At discharge, 54% (95% confidence interval: 47%–60%) of the patients met this criterion.ConclusionThe PDAS appears to be a clinically valid, scalable and responsive measure of the severity of psychotic depression in older adults.

Ankylosing Spondylitis Disease Activity Score (ASDAS) is a very important tool for measuring disease activity in patients with axial spondyloarthritis (axSpA). This study was aimed to develop a culturally adapted, valid and reliable Bengali version of questionnaire for the ASDAS. The original English ASDAS was translated into Bangla and adapted in the local socio-cultural context, following standard international recommendations. Content validity of the adapted Bangla version was assessed by the item-level & scale level content validity indices (I-CVI & S-CVI). A total 120 patients with axSpA were assessed in the study. For construct validity, correlation between ASDAS with BASDAI, ESR, CRP, Maastricht enthesitis score, physician's global assessment and BASMI was assessed by Spearman's rank correlation coefficient. Internal consistency and test-retest reliability were assessed using Cronbach's alpha coefficient and intraclass correlation coefficient respectively. I-CVI for each item was 1 and S-CVI was 1. ASDAS-ESR and ASDAS-CRP showed strong correlation (Spearman's correlation coefficient >0.5) with BASDAI, ESR, MASES and physician global assessment of disease activity. The scale demonstrated excellent internal consistency (Crohnbach's alpha=0.703) and test-retest reliability (ICC=0.98). The adapted Bangla version of the ASDAS demonstrated acceptable psychometric properties (validity & reliability) in Bangladeshi patients with axSpA.

Objective: To investigate the application value of apparent diffusion coefficient value in the pathological type, histologic grade, and presence of lymph node metastases of esophageal carcinoma. Materials and Methods: Eighty-six patients with pathologically confirmed esophageal carcinoma were divided into different groups according to pathological type, histological grade, and lymph node status. All patients underwent conventional magnetic resonance imaging and diffusion-weighted imaging scan, and apparent diffusion coefficient values of tumors were measured. Independent sample t test and 1-way variance were used to compare the difference of apparent diffusion coefficient value in different pathological types, histologic grades, and lymph node status. Correlation between the apparent diffusion coefficient value and the histologic grade was evaluated using Spearman rank correlation test. Receiver operating characteristic curve of apparent diffusion coefficient value was generated to evaluate the differential diagnostic efficiency of poorly and well/moderately differentiated esophageal carcinoma. Results: No significant difference was observed in apparent diffusion coefficient value between esophageal squamous cell carcinoma and adenocarcinoma and in patients between those with and without lymph node metastases ( P > .05). The differences of apparent diffusion coefficient value were statistically significant between different histologic grades of esophageal carcinoma ( P < .05). The apparent diffusion coefficient value was positively correlated with histologic grade ( rs = 0.802). The apparent diffusion coefficient value ≤1.25 × 10−3 mm2/s as the cutoff value for diagnosis of poorly differentiated esophageal carcinoma with the sensitivity of 84.3%, and the specificity was 94.3%. Conclusions: The performance of apparent diffusion coefficient value was contributing to predict the histologic grade of esophageal carcinoma, which might increase lesions characterization before choosing the best therapeutic alternative. However, they do not correlate with pathological type and the presence of lymph node metastases of esophageal carcinoma.

Purpose. To assess the repeatability, reproducibility, and comparability of measurements of subjective and objective forward scattering in healthy subjects.Methods. We prospectively examined twenty eyes of 20 healthy volunteers (7 men and 13 women; ages, 28.4 ± 4.1 years). The logarithmic straylight value (log(s)) and the objective scattering index (OSI) were measured with a straylight meter (C-Quant) and a point-spread function meter (OQAS), respectively.Results. The 95% limits of agreement (LoA) between first and second measurements ranged from −0.211 to 0.207 for the C-Quant and from −0.302 to 0.477 for the OQAS. The intraclass correlation coefficients for the repeatability of the log(s) and OSI measurements were 0.815 and 0.926, respectively. The mean difference between examiners was −0.051 ± 0.133 (95% LoA; −0.311 to 0.209) for the C-Quant and 0.080 ± 0.307 (−0.522 to 0.682) for the OQAS. There was a modest, but significant, correlation between the log(s) and the OSI (Spearman correlation coefficientr=0.498,p=0.026).Conclusions. The C-Quant and the OQAS provide good repeatability and reproducibility, although the OQAS measurement provides a slightly higher ICC than the C-Quant measurement. The subjective forward scattering may be to some extent expressed in the objective forward scattering in healthy subjects.

Purpose: To propose a simple non-invasive method for screening patients at risk for angle closure using anterior segment OCT. Methods: Scans of nasal and temporal iridocorneal angles in glaucoma suspect patients were performed using OCT. Upon identifying Schwalbe’s line, the integrated caliper tool was used to draw a line to the nearest point of the iris to produce a measure ‘S-I’. Gonioscopy was performed and angles graded according to Shaffer’s classification to assess the correlation between both methods. Results: Thirty-four images were available for analysis. Spearman correlation coefficients between S-I anf gonioscopy grades were 0.81 for nasal and 0.77 for temporal quadrants respectively. Intraobserver ICC calculations demonstrated excellent reproducibility (0.98 and 0.99 for nasal and temporal angles) and excellent interobserver correlation (0.94 and 0.93). The diagnostic cutoff value of S-I for occludable angles was established at 330mm.
Conclusion: S-I measurement strongly correlates with gonioscopy and may be a suitable alternative for evaluating risk for angle closure.

Abstract The goal of this study was to examine the relationship between kinematics, motor abilities, anthropometric characteristics, and the initial (10 m) and secondary (30 m) acceleration phases of the 100 m sprint among athletes of different sprinting performances. Eleven competitive male sprinters (10.96 s ± 0.36 for 100 with 10.50 s fastest time) and 11 active students (12.20 s ± 0.39 for 100 m with 11.80 s fastest time) volunteered to participate in this study. Sprinting performance (10 m, 30 m, and 100 m from the block start), strength (back squat, back extension), and jumping ability (standing long jump, standing five-jumps, and standing ten-jumps) were tested. An independent t-test for establishing differences between two groups of athletes was used. The Spearman ranking correlation coefficient was computed to verify the association between variables. Additionally, the Ward method of hierarchical cluster analysis was applied. The recorded times of the 10 and 30 m indicated that the strongest correlations were found between a 1- repetition maximum back squat, a standing long jump, standing five jumps, standing ten jumps (r = 0.66, r = 0.72, r = 0.66, and r = 0.72), and speed in the 10 m sprint in competitive athletes. A strong correlation was also found between a 1-repetition maximum back squat and a standing long jump, standing five jumps, and standing ten jumps (r = 0.88, r = 0.87 and r = 0.85), but again only for sprinters. The most important factor for differences in maximum speed development during both the initial and secondary acceleration phase among the two sub-groups was the stride frequency (p<0.01).

AbstractThe objective of this study is to ascertain the effect of clinical experience on pediatric intensive care unit (PICU) residents' learning curve for central venous catheter placement in critically ill children. It was a 58-month retrospective observational study. The setting was multivalent PICU with 20 beds at a tertiary children's hospital. The subjects were PICU residents undergoing training in central venous catheter placement. During the study period, 22 residents were enrolled in the study, and 1,157 catheter placement procedures (485 central venous, 605 peripherally inserted central venous, 57 hemodialysis, and 10 “other” types of catheter placement procedures) were analyzed. The total success rate was 82.7%. After ultrasound-guided training simulation in catheter placement, the residents' learning curve for the procedure rose from 71% in the clinical setting at the first trial to 75% at the fourth trial and 80% by the 24th trial. Significant positive correlation was found between procedure success and number of trials with a Spearman coefficient (p < 0.019). Adequate clinical experiences were necessary for PICU residents to achieve competency in central venous catheter placement in critically ill children.

Full textAbstract:
In our paper we compare two centrality measures of networks, betweenness and Linerank. Betweenness is widely used, however, its computation is expensive for large networks. Calculating Linerank remains manageable even for graphs of billion nodes, it was offered as a substitute of betweenness in [12]. To the best of our knowledge the relationship between these measures has never been seriously examined. We calculate the Pearson?s and Spearman?s correlation coefficients for both node and edge variants of these measures. For edges the correlation tends to be rather low. Our tests with the Girvan-Newman algorithm [16] also underline that edge betweenness cannot be substituted with edge Linerank. The results for the node variants are more promising. The correlation coefficients are close to 1. Notwithstanding, the practical application in which the robustness of social and web graphs is examined node betweenness still outperforms node Linerank. We also clarify how Linerank should be computed on undirected graphs.

Background:Dermatomyositis is a multi organ autoimmune disease wich is commonly complicated with interstitial lung disease. Chest high-resolution computed tomography (HRCT) is still considered the diagnostic gold standard for interstitial lung disease and is quantification, however he increasing use of lung ultrasound may play an important role in the future.Objectives:The aim of our study was to determine the diagnostic value of lung ultrasound in the detection and progression of interstitial pulmonary disease in patients with dermatomyositis.Methods:Twenty two subjects with dermatomyositis diagnosed according to the American College of Rheumatology criteria were enrolled (6 males, 16 females; mean age: 15,8 ± 8.8 years; range: 6 to 29 years). All subjects underwent high resolution computed tomography followed by transthoracic ultrasound for comet tail sign detection and pleural irregularity in order to predict the degree of interstitial lung disease. The modified transthoracic ultrasound assessment was performed at 06 thoracic regions each side. The Warrick score was calculated according standard high-resolution chest computed tomography images that were evaluated independently from each other by two thoracics radiologists.Results:A significantly positive correlation between transthoracic ultrasound and the severity of pulmonary involvement, as seen by the number of B lines (Spearman ‘s correlation coefficient = 0.80, p < 0.001), and the number of positive areas (regions wih more than 3 B lines) (Spearman ‘s correlation coefficient = 0.75, p < 0.001) were found. When compared with high-resolution chest computed tomography as the gold standard method, the sensitivity, specificity, of transthoracic ultrasound was 96.4%, 83,3% respectively. Addicionally the number of B lines (sum of 35 or more B lines) and a number of B lines positive areas (7 or more regions with at least 3 B lines) cut of allowed to discriminate the inflamatory pattern (ground glass) to those with structural pattern (honeycomb and pulmonary cysts).Conclusion:Our study showed that transthoracic ultrasound comet tails scoring system could be useful in the assessment of the pulmonary involvement in patients with dermatomyositis, and should be considered as a primary screening exam to exclude lung involvement, rather than routine chest CT scans in assimptomatic patients.Disclosure of Interests:None declared

Objective To analyze the perception of the handicap in patients with tinnitus and hearing loss as well as the possible associations between the variables hearing loss, loudness, onset, frequency and annoyance by tinnitus, and the correlation between the visual analogue scale (VAS) and the Tinnitus Handicap Inventory (THI). Methods A total of 30 patients with complaints of tinnitus and the presence of sensorineural hearing impairment were selected for this cross-sectional, observational, and descriptive study. The loudness of the tinnitus was measured by a VAS and classified as mild, moderate, or severe. The THI was classified as slight, mild, moderate, severe, and catastrophic. Data were submitted to statistical analysis using the Fisher exact test and Spearman correlation coefficient. Results Eleven male (36.7%) and 19 female (63.3%) subjects with a mean age of 56.5 years old were evaluated. There was no significant association between loudness, annoyance, time and frequency of tinnitus, nor between hearing loss and tinnitus. There was a significant association between the variables hearing loss and loudness, and a weak correlation between VAS and THI. Conclusion Tinnitus has a practical impact in the lives of patients with hearing loss in terms of catastrophic, functional, and emotional aspects, regardless of loudness, frequency, or time of onset. Hearing loss was a factor that had an impact on the loudness of tinnitus. There was no statistically significant correlation between VAS and THI.

BACKGROUND: The delayed blood pressure recovery (BPR) at post-exercise has been in association with a major risk of cardiovascular disease and death. OBJECTIVE: The study focused on evaluating the systolic and diastolic blood pressure recovery (SBPR, DBPR) and the autonomic modulation following treadmill exercise in healthy young adults. Although considerable literature had been published about BPR and HRV, the association between BPR and ultra-short-term HRV has not yet been completely described. METHODS: Fifteen subjects performed exercise with three different intensities on a treadmill, the speed was 6 km/h, 9 km/h, 12 km/h, respectively. SBP and DBP was measured per 30 s in each trial. The synchronous 5-min electrocardiogram (ECG) signals were recorded and HRV30s parameters including SDNN30s, RMSSD30s, SDNN30s/RMSSD30s, SD130s, SD230s and SD130s/SD230s were calculated every 30 s periods in 5 min ECG signals to match the corresponding BPR. RESULTS: The intraclass correlation coefficient (ICC) values and the Bland-Altman plots indicated good consistency and repeatability between HRV30s and HRV5min at three post-exercise trials, with most ICC values > 0.75. Besides, SBPR and DBPR generally decreased and returned to the Rest level in 5 mins. The Spearman correlation coefficients showed strong relationships between BPR and HRV30s sympathetic-vagal balance parameters, i.e., ratio SDNN/RMSSD and ratio SD1/SD2. CONCLUSIONS: These observations represented a new insight into the cardiovascular regulation at post-exercise, which could contribute to physical exercise areas in the future.
