Abstract Relationships between performance test traits (growth rate, backfat thickness, loin depth, lean meat percentage, exterior, phenotypic selection index) and longevity traits (length of productive life, number of litters, total number of weaned pigs, number of weaned piglets per year, number of litters per year) in Landrace sows were evaluated using canonical correlation analysis. The data set consisted of 23,012 purebred sows that farrowed from 1994 to 2011 in 161 herds. The first three canonical correlations (0.37, 0.25, 0.07) were highly significant (P<0.0001). Correlations of the first canonical variate with the original measured variables indicated that sows with high values for this variate had lower growth rate (r=-0.31) and loin depth (r=-0.43), greater backfat thickness (r=0.23), as well as being older at birth of their last litter (r=0.98). These sows also had a greater number of litters (r=0.94) and better lifetime efficiency (r=0.61 and r=0.70 for number of weaned piglets per year and number of litters per year, respectively). Canonical loadings for the second canonical function indicate that sows with high values for the second set of variates had high growth rate (r=0.79) and phenotypic selection index (r=0.83), excellent conformation (r=0.62), as well as better efficiency in pig production (r=0.67). The squared multiple correlations show that the first canonical variate of the performance traits is a poor predictor of longevity (0.13) and nearly useless for predicting efficiency traits (0.07). Performance test traits explain 11% of the variance in the variables of longevity and lifetime productivity, whereas dependent variables explain only 3% of the variance in performance test traits. The relationships between performance test data and subsequent lifetime productivity or longevity were significant and unfavourable but low for Polish Landrace population

Next, we give an error estimate in the approximation of a function in the Lipschitz class and establish a Voronovskaja type theorem. Also, we define the associated GBS(Generalized Boolean Sum) operators and study the degree of approximation of Bögel continuous and Bögel differentiable functions by these operators with the aid of the mixed modulus of smoothness. Finally, we show the rate of convergence of the bi-variate operators and their GBS case for certain functions by illustrative graphics and tables using MATLAB algorithms.</p>

Abstract Background Chronic myeloid leukaemia (CML) presenting in accelerated phase (AP) is uncommon and there are few data on predictive co-variates for outcomes of tyrosine kinase-inhibitor (TKI)-therapy. Moreover, it is unknown which outcomes of TKI-therapy in these persons correlate with European LeukemiaNet (ELN) definitions of warning and failure which were developed in people in chronic phase or whether imatinib and 2 nd generation tyrosine kinase-inhibitors (TKIs) are equally effective. Objective Identify co-variates correlated with outcomes of TKI-therapy in persons with CML presenting in AP diagnosed by MD Anderson or World Health Organization (WHO) criteria and develop a predictive score. Determine which outcomes correlate with ELN criteria of warning and failure. Compare outcomes of initial therapy with imatinib versus 2 nd-generation TKIs. Methods We interrogated data from 312 and 334 consecutive subjects with CML presenting in AP and receiving imatinib or a 2 nd-generation TKI as initial therapy. Diagnosis of AP was based on widely-accepted MD Anderson or WHO criteria. Demographic, clinical and laboratory co-variates significantly correlated with outcomes were analyzed in a Cox multi-variable regression model. Propensity score matching was done to compare outcomes of initial therapy with imatinib versus a 2 nd generation TKIs. Results In the cohort defined by MD Anderson criteria there were 197 males (63%) with a median age of 41 years (Interquartile Range [IQR], 30 - 54 years). 106 subjects (34%) had ≥ 1 co-morbidities. Median haemoglobin concentration was 99 g/L (range, 40-176 g/L), WBC concentration, 138 x 10E+9/L (range, 3-797 x10E+9/L), platelet concentration, 450 x 10E+9/L (range, 11-4094 x10E+9/L) and percentage blood or bone marrow blasts (whichever was higher), 4% (range, 0-27%). Non-mutually exclusive criteria for classifying subjects as AP included: (1) 15-29% blasts (n = 22, 7%); (2) blood basophils ≥ 20% (n = 184, 59%); (3) platelets < 100 × 10E+9/L unrelated to therapy (n = 31, 10%); (4) clonal evolution (n = 45, 15%); (5) ≥ 2 features (n = 30, 10%). Co-variates associated with failure-free survival (FFS) were haemoglobin concentration < 100 g/L (HR = 1.9; 95% Confidence Interval [CI], 1.1, 3.1; p = 0.014) and blasts > 4.5% (HR = 1.8 [1.1 - 2.9]; p = 0.013). Co-variates associated with progression-free survival (PFS) were platelets < 230 × 10E+9/L (HR = 3.3 [1.7, 6.5]; p < 0.001), blasts > 4.5% (HR = 2.4 [1.3, 4.6]; p = 0.007) and ≥ 1 co-morbidities (HR = 2.4 [1.2, 4.7]; p = 0.010). Co-variates associated with survival were haemoglobin concentration < 100 g/L (HR = 3.3 [1.1, 10.2]; p = 0.04), platelets < 230 × 10E+9/L (HR = 11.4 [3.9, 33.3]; p < 0.001) and ≥ 1 co-morbidities (HR = 6.7 [2.3, 19.5]; p < 0.001). Next, we divided subjects into 4 cohorts: (1) low-risk (no adverse co-variate; n = 49); (2) intermediate-1 risk (1 adverse co-variate; n = 116); (3) intermediate-2 risk (2 adverse co-variates; n = 92); and (4) high-risk (≥ 3 adverse co-variates; n = 47) with significant different probabilities of FFS, PFS and survival (all p-values < 0.001). Using the 2020 ELN criteria for w arning at 3 months was significantly-associated with worse FFS (HR = 3.1 [1.7, 5.7]; p < 0.001). Failure at 3 months was significantly associated with worse PFS (HR = 9.3 [4.3, 18.8]; p < 0.001) and survival (HR = 6.2 [2.0, 19.2]; p = 0.002). In propensity score matching analyses subjects receiving initial therapy with imatinib had lower probabilities of complete cytogenetic response (CCyR; HR = 1.3 [1.0, 1.8]; p = 0.079), major molecular response (MMR; HR = 1.2 [0.8, 1.7; p = 0.386) and molecular response 4.5 (.5; HR = 1.8 [1.1, 3.1]; p = 0.019). However, other endpoints including FFS, PFS and survival were similar for both interventions. Similar results in the subjects diagnosed as AP using the WHO criteria. Conclusions We identify co-variates associated with several outcomes of TKI-therapy in persons presenting in AP CML and used these to develop a prognostic score. We show the 2020 ELN criteria for warning and failure to TKI-therapy developed in persons in chronic phase also operate in subjects diagnosed in AP. Lastly, using propensity score matching we show that whilst some landmarks are achieved more rapidly in persons initially treated with a 2 nd generation TKI, FFS, PFS and survival are similar to those in persons initially treated with imatinib. Our data should help inform physicians treating person with CML presenting in AP. Figure 1 Figure 1. Disclosures No relevant conflicts of interest to declare.

The titled study is concerned with the dropout of females from secondary schools in District Bajaur due to the economic impediments of the study population. A sample size of 169 respondents was taken possessively by using Sekaran criteria. A cross-sectional study design was developed for the collection of data according to the conceptual framework showing the dependent variable (Nature of Drop out) and independent variable (Economic Impediments). Furthermore,Uni variate and Bi-variate analysis was conducted through the use of SPSS software. After the analysis of data at the Bi-variate level, a highly significant association (P=0.000) was found between the Nature of Drop out and economic indicators(statements) namely the most dominant cause of high drop out ratio was financial problems, money was considered a wastage when it’s spent on female education, money was well spent if sons are getting the education and parents prioritize boy’s education more as compared to their girl child, along with the cultural norms and beliefs constraining females education, as well as parents, believed that religious education is more important than formal education.

Hierarchical cluster (HCA) and canonical correlation (CCA) analyses were employed to explore the multivariate relationships among chemical components (proximate, mineral and lipidic components) of lean beef longissimus dorsii lumborum (LDL) and selected carcass traits of cattle fattened on pasture under tropical conditions (bulls, n = 60; steers, n = 60; from 2.5 to 4.0 years of age, estimated by dentition). The variables backfat thickness (BFT), Ca, Mn, Cu, C14:0, C15:0, and C20:0 showed the highest coefficients of variation. Three clusters were defined by the HCA. Out of all carcass traits, only BFT differed significantly (p < 0.001) among clusters. Clusters significantly (p < 0.001) differed for total lipids (TLIPIDS), moisture, dry matter (DM), fatty acid composition, cholesterol content, and mineral composition (except for Fe). The variables that define the canonical variate “CARCASS” were BFT and degree of marbling (MARBLING). TLIPIDS was the main variable for the “PROXIMATE” canonical variate, while C16:0 and C18:1c had the most relevant contribution to the “LIPIDS” canonical variate. BFT and MARBLING were highly cross-correlated with TLIPIDS which, in turn, was significantly affected by the IM lipid content. Carcass traits were poorly correlated with mineral content. These findings allow for the possibility to develop selection criteria based on BFT and/or marbling to sort carcasses, from grass-fed cattle fattened under tropical conditions, with differing nutritional values. Further analyses are needed to study the effects of sex condition on the associations among carcass traits and lipidic components.

Patients with cirrhosis have hyperdynamic circulation with abnormally distributed blood volume and widespread arteriovenous communications. We aimed to detect possible very early (i.e., before 4 s) and early (i.e., after 4 s) central circulatory transits and their potential influence on determination of central and arterial blood volume (CBV). Thirty-six cirrhotic patients and nineteen controls without liver disease undergoing hemodynamic catheterization were given central bolus injections of albumin with different labels. Exponential and gamma variate fits were applied to the indicator dilution curves, and the relations between flow, circulation times, and volumes were established according to kinetic principles. No significant very early central circulatory transits were identified. In contrast, early (i.e., 4 s to maximal) transits corresponding to a mean of 5.1% (vs. 0.8% in controls; P < 0.005) of cardiac output (equivalent to 0.36 vs. 0.05 l/min; P < 0.01) were found in cirrhotic patients. These early transits averaged 7.7 vs. 12.7 and 17.2 s of ordinary central transits of cirrhotic patients and controls, respectively ( P < 0.001). Early transits were directly correlated to the alveolar-arterial oxygen difference in the cirrhotic patients ( r = 0.46, P < 0.01) but not in controls ( r = 0.04; not significant). There was good agreement between the CBV determined by the conventional indicator dilution method and that determined by separation of early and ordinary transits by the gamma variate fit method (1.51 vs. 1.53 liter; not significant). In conclusion, no very early central circulatory transits were identified in cirrhotic patients. A significant part of the cardiac output undergoes an early transit, probably through pulmonary shunts or areas with low ventilation-perfusion ratios in cirrhotic patients. Composite determination of CBV by the gamma variate fit method is in close agreement with established kinetic methods. The study provides further evidence of abnormal central circulation in cirrhosis.

Under an epistemic interpretation, an upper probability can be regarded as equivalent to the set of probability measures it dominates, sometimes referred to as its core. In this paper, we study the properties of the number of extreme points of the core of a possibility measure, and investigate in detail those associated with (uni- and bi-)variate p-boxes, that model the imprecise information about a cumulative distribution function.

<p>The nature of stock market integration has been an issue for almost a decade; this issue is more complicated toward Shari’ah compliance between countries since there are differences of companies screening process that can be classified as Shari’ah compliances. The differences make the integration of Shari’ah compliances stock market become a major issue in trying to answer the question whether one country can be the placed for Shari’ah portfolio diversification. This study aims to measure Shari’ah compliances integration and portfolio diversification in Indonesia and Malaysia Shari’ah compliances toward other Shari’ah compliances in the world. Six Shari’ah compliances are selected based on countries level of development and geographical factor. This studies relies on two major time series investigation techniques, namely the Auto-Regressive Distributed Lag (ARDL) approach and multi-variate Vector Error Correction Mechanism (VECM), based on the Generalized Methods of Moments (GMM). The ARDL approach is used to determine the existence of long run integration among Shari’ah compliances, while the multi-variate VECM based on the GMM is adopted to provide a robust analysis of short and long-run dynamic causal linkages among the stock markets.</p><p><br />Keywords: Efficient Market Hypothesis, Portfolio Diversification, Shari’ah compliances Integration</p>

The Messenger of ALLAH Almighty, the Holy Prophet MUHAMMAD (peace be upon him) has said "Ar-Rashi Wal Murtashi Kila huma Finnar" that mean "the giver and taker of bribes (corrupt) will both go to the fire of hell". This research analyzes corruption's effect on existing social values in Peshawar region of Islamic Republic of Pakistan. A total of 150 respondents were selected as sample using stratified random sampling technique for study using Likert scale as measurement tool in interview schedule. The bi-variate and uni-variate analyses were made for reaching results. The existence of the effect of "corruption perception" as independent variable's effects were assessed on the "social values in political institutions" as dependent variable by applying Chi-square test. Furthermore, Gamma (y) statistics' application was made for finding the bond and relationship's direction. It was concluded that a significant association prevails regarding corruption perception with organized corruption alliance between government servants and politicians (P=0.002), politicians who are corrupt do safeguard corrupt interests (P=0.000) and favoured political environment (P=0.000). Moreover, posting candid politicians on significant government posts (P=0.000), removing political influence form bureaucracy (P=0.000), making politicians accountable to agencies related to stopping corruption (P=0.000), recompensing politicians of honesty (P=0.033), sensitizing politicians to be aware of corruption (P=0.000) and applying court's judgements regarding reducing corruption (P=0.000) were found significantly associated with improving state of corruption.

Multielement taxonomy and shape analysis have led to substantial revisions in the taxonomic concepts of 13 Frasnian species of Palmatolepis, which previously have been based largely on visual discrimination of the Pa elements. Septimembrate apparatuses have been recognized in three species and diagnostic Pb elements are associated with the Pa elements of eight others. The multielement reconstructions thus derived provide the a priori classification that is tested by the canonical variate analysis of the outlines of the Pa elements. The outlines are digitized from a TV image and quantified by calculating mean tangent angles within a specified number of intervals between landmarks. The mean tangent angles for each interval are the variables used in the canonical variate analysis. In a series of comparisons limited to three species each, all 13 species separate into isolated clusters that are completely congruent with the a priori groups based, with two exceptions, on multielement taxonomy. Thus, shape analysis provides a rigorous separation of closely similar species that have been difficult to distinguish by visual discrimination of the Pa elements. Shape analysis is treated herein as an integral part of the systematic descriptions. Newly described species are P. bohemica, P. boogaardi, P. luscarensis, and P. muelleri. The new taxonomic concepts lead to significant revisions in the biostratigraphic ranges of a number of species of Palmatolepis involved in the zonation and graphic correlation of the Frasnian Stage.

Factors related to physical behaviour of children are important in understanding the characteristics of their physical activity. Apart from the factors of physical environment, social and demographical factors are also related to physical activity levels. Randomly selected 669 children (9.9±0.8 years; 48.8% boys) from randomly selected Slovenian elementary schools participated in this study. All data were obtained during a single measurement in May 2010. The standardized questionnaire The Quality of Life Survey was used to measure physical activity (PA) levels as well as social and demographic factors which could be associated with it. The results indicated higher PA levels in boys than in girls (704±286 min/week vs. 617±268 min/week; p<.001). The analysis of variance confirmed higher PA levels in girls with parents of a higher socioeconomic status (SES) (p=.0018); in boys, there were no differences in PA levels according SES (p=.580). In both the boys (p=.047) and girls (p=.021) PA levels were higher if their whole family were members of any sport club. However, family structure was not related to PA levels in either boys (p=.648) or girls (p=.132). In boys, the bi-variate regression analysis showed a positive correlation with mother’s educational level (r=.090), with the number of children in the family (r=.150), with the child’s attitude that active commute to school is attractive (r=.108) and that child’s peers actively commute to school (r=.129), whereas a negative correlation was obtained with fear the child would become a victim of violence or harassment on the way to school (r=-.097). In girls, bi-variate regression analysis showed a positive correlation with mother’s educational level (r=.094), with the child’s attitude that active commute to school is attractive (r=.092) and that child’s peers actively commute to school (r=.221), whereas a negative correlation was established with fear the child would become a victim of violence or harassment on the way to school (r=-.061) or at recreational and sporting facilities (r=-.046). According to low correlations in bi-variate analysis, we conclude that other factors, such as, for example, physical environment, might be strongly related to physical activity levels in children and need to be taken into account when preparing interventions for physical activity enhancement.

Techniques currently available in the literature in dealing with problems in geometric probabilities seem to rely heavily on results from differential and integral geometry. This paper provides a radical departure in this respect. By using purely algebraic procedures and making use of some properties of Jacobians of matrix transformations and functions of matrix argument, the distributional aspects of the random p-content of a p-parallelotope in Euclidean n-space are studied. The common assumptions of independence and rotational invariance of the random points are relaxed and the exact distributions and arbitrary moments, not just integer moments, are derived in this article. General real matrix-variate families of distributions, whose special cases include the mulivariate Gaussian, a multivariate type-1 beta, a multivariate type-2 beta and spherically symmetric distributions, are considered.

The common assumptions of independence and rotational invariance of the random points are relaxed and the exact distributions and arbitrary moments, not just integer moments, are derived in this article. General real matrix-variate families of distributions, whose special cases include the mulivariate Gaussian, a multivariate type-1 beta, a multivariate type-2 beta and spherically symmetric distributions, are considered.

The major objective of this research study was to assess the impact of corruption upon the prevalent social values in Peshawar city, Pakistan. A sample size of 150 respondents was selected through stratified random sampling to ascertain respondents’ attitudes towards phenomena at hand with Likert scale as measurement tool. At first stage uni-variate analysis and then bi-variate analysis were carried out to determine outcomes. The dependent variable (corruption perception) was cross-tabulated with the independent variable (social values and its societal aspects). A chi-square test was used to determine the association between dependent and independent variables. In addition, Gamma (g) statistics were applied to determine the strength and direction of the relationship. The study found a significant and positive association between corruption perception with social values safeguarding the interest of rich (P=0.022), morality as existing behavioral standard in society (P=0.000), experience of corruption (P=0.000), significance of social pressure (P=0.000), use of social pressure (P=0.000), degradation of social values in society due to corruption (P=0.000), biased evaluative standards for various social classes (P=0.000). In addition, people who refused to accept and pay bribes, had followers in the society (P=0.037), increasing the magnitude of corruption with an increase in official rank (P=0.007), and finally, that an ethical environment based on social norms and values reduces corruption (P=0.000). The study concluded that, in the site of study, the social order is under deterioration due to corruption assuming the status of an emerging social value due to its practice amongst members of society in various fields of life. However, people still considered the prevalent social order strong enough to combat this changing dynamic by creating an ethical environment based on social alienation for those who acted corruptly.

Introduction: Estimation of race plays a significant role in establishing personal identity in forensic anthropology. A cervical vertebra is one of the bones that is least researched in forensic applications. Our study aims to investigate the morphologic variations of the fourth cervical vertebrae (C4) between the different major races in the adult Malaysian population using a three-dimensional (3D) geometric morphometrics method. Methods: Computer tomography images of C4 vertebra, which consist of 386 subjects (169 Malay, 82 Chinese, and 135 Indian) were collected retrospectively from University of Malaya. Twenty-eight landmarks were placed on the images. Procrustes MANOVA, canonical variates analysis(CVA), discriminant function analysis (DFA), and linear measurement were performed using Planmeca Romexis, Checkpoint Stratovan, Morpho J, and Graphpad Prism software respectively to analyze the morphological variations of C4. Results: Procrustes MANOVA showed significant differences in the shape (p <0.0001) and centroid size (p = 0.0003) of the C4 vertebra between races. Canonical variate analysis showed significant differences for Mahalanobis (p <0.0001) and Procrustes (p <0.0001) distances among races. Besides that, a cross-validation value of 66.5% was demonstrated by discriminant function analysis. The use of linear measurements reveals no significant differences between the races, thesemeasurements are the vertebral body height, anterior-posterior length of the vertebral body, length of superior articular facet, and spinous process length. Both intra- and inter-observational reliabilities showed that acceptable human errors for measurement accuracy. Conclusions: Morphologic variations in the shape of C4 can assist in race estimation of the adult Malaysian population using the 3D geometric morphometric approach.

Vascular transit time is an important indicator of microcirculatory health. We present a second-order-plus-dead-time (SOPDT) model for robust estimation of kinetic parameters characterizing microvascular bolus passage using two-photon fluorescence microscopy (2PFM) in anesthetized rats receiving somatosensory stimulation. This methodology enables quantification of transit time, time-to-peak, overshoot, and rate of bolus passage through the microvascular network. The overall transit time during stimulation, of 2.2±0.1 seconds, was shorter ( P∼0.0008) than that at rest (2.7±0.2 seconds). When compared with conventional γ-variate modeling, the SOPDT modeling yielded better quality of fit both at rest ( P<0.0001) and on activation ( P<0.001).

Background: Immunization is one of the most cost-effective interventions to prevent the suffering that comes from avoidable sickness, disability and death. In India, though immunization coverage has improved over the past few years, the country still accounts for the largest number of children who are not immunized i.e. 7.4 million. So, this study was taken up to assess the immunization coverage among children in District Gautam-Budh Nagar of Uttar Pradesh and to decipher the causes behind the partial immunization/non- immunization. Methods: A cross-sectional study was conducted during June-August 2015 in an urban resettlement colony of District Gautam-Budh Nagar in Uttar Pradesh among 210 children aged 12-23 months selected using WHO 30X7 cluster sampling technique. Results: A total of 210 children were covered, of which 72.9% children were fully immunized, 19.0% children were partially immunized, whereas, 8.1% children did not receive even a single dose of any vaccine, thus constituting a total of 27.1% children with partial/no immunization. On bi-variate analysis, significant association was observed between immunization status among children and caste (p=0.047), mother’s education (p=0.01), father’s education (p=0.000) and socio-economic status (p=0.003). On multi-variate analysis, however, only father’s educational status was found to be significantly associated. The major reasons for partial/non-immunization among children were Ignorance (80.7%) followed by unavailability of vaccines (7.0%). Conclusions: Immunization coverage found in the present study is still way short of the target of universal coverage. Therefore, health planners and policy makers in our country should develop a comprehensive strategy to achieve universal immunization coverage.

AbstractBackgroundAlthough alterations in medial temporal lobe structures have been previously associated with use of cannabis, one of the most widely used illicit drugs, whether such alterations are a cause or effect of cannabis use has been unclear.MethodsIn this cross-sectional observational study involving 404 twins/siblings, we have compared cortical thickness and surface area between groups of gender-matched sibling-pairs (concordant cannabis unexposed, concordant exposed and discordant for cannabis exposure) using permutation tests after controlling for potential confounds. Bi-variate polygenic model was used to assess the genetic and environmental contributions underlying cortical morphological phenotypes and frequency of cannabis use.ResultsCortical thickness of the right entorhinal cortex was significantly lower in the concordant exposed siblings compared to both discordant unexposed and discordant exposed groups [false discovery rate (FDR)-corrected, q < 0.05]. The association between the right entorhinal cortex thickness and frequency of cannabis use is due to the contribution of significant shared additive genetic (ρg = −0.19 ± 0.08; p = 0.02) factors but not unique environment (ρe = 0.05 ± 0.09; p = 0.53). Significantly lower surface area of the right entorhinal cortex in discordant exposed group compared with the discordant unexposed group furnishes preliminary evidence in support of causal effect of cannabis use (FDR-corrected, q < 0.05). However, bi-variate polygenic model-based analysis did not show any significant effect.ConclusionsShared genetic liability may underlie the association between cannabis exposure and thinner right entorhinal cortex. Prospective longitudinal studies are necessary to definitively disentangle the cause–effect relationships of cannabis use.

In the theory of multivariate statistics, it is well known that given a sample of n independent p-variate normally distributed random vectors with a common variance-covariance matrix, if at least one of the n vectors has nonzero means, then the sum of squares about the sample mean of the n vectors has a noncentral Wishart distribution. However, a detailed proof for this known result is rarely found in literature. In this paper, we present a formal and complete proof for the well-known result together with an example of its applications.

Background: The study of health seeking behavior is a useful research for developing society like Bangladesh. Many factors such as socio-demographic, socio-cultural, socio-economic and health service system influence health seeking behavior. This study assessed the health seeking behavior among the households’ areas in Sylhet city.Methods: This study has used multistage cluster sampling method for data collection. Using multistage cluster sampling, 150 were selected. A household survey questionnaire was used to collect data. Information about socio-demographic characteristics, socio-economic factors, socio-cultural factors by residential areas, and their influences on seeking health care have been gathered. Chi-square and uni-variate analysis has been applied in this study.Results: The association between socio-economic status and the status of residential area has a significant relationship. The p value (0.005) indicates most of the socio-demographic factors except sanitary system associated with the status of residential households. The association among income range, total expenditure, medical expense, income interfere by perceiving illness, health insurance, main source of health care, reason for choosing specific source of health care and the pattern of health seeking behavior of the residential areas are statistically significant. Uni-variate analysis is an interaction between residence and reason for choosing specific health care on main source of health care among the households of the residential areas under this study (p=0.001).Conclusions: Understanding of health seeking behaviour is essential to provide need-based health care services to the population. Many factors like gender, age, type of illness influences the health seeking behaviour.

Knowledge of Congenital anomalies (CAs) among the public, especially reproductive age women have a significant role in reducing the incidence. However, there is a dearth of studies conducted on this issue in our country. This study was aimed to assess the pregnant women’s knowledge of CAs at the antenatal care clinic of Arba Minch General Hospital. Institution based cross-sectional study was conducted between December 2017 and September 2018. Semi-structured questionnaire was used to collect the data. Data were cleaned, entered and analysed by using SPSS version- 20 software packages. Besides descriptive statistics, Bi-variate and Multi-variate logistic regression analyses were done to explore the predictors of women’s level of knowledgetoward CAs. P-value < 0.05 was considered as statistically significant. A total of 392 pregnant women had participated in the present study. From total respondents, only 11.0% of the pregnant women have known that many of CAs are of genetic origin, and a significant proportion of the women had believed that CA is a disease acquired by pregnant women (39.0%), and it occurs in a baby due to the sin of families (48.5%). Only 189 (48.2%) women had adequate overall knowledge about CAs. The participants had good knowledge of the risk factors than their specific knowledge of CAs. The level of education and occupation were significantly associated (P<0.05) with the women’s overall knowledge of CAs. In conclusion, the women’s knowledge of CAs in this study was found less. Appropriate strategies should be designed and implemented to improve women’s knowledge of congenital anomalies.

Abstract In acute leukemia prolonged survival is impossible without obtaining a CR. Based on the acute leukemia model, myeloma therapy has gradually been intensified with the aim to increase the CR rate as a first important step to improve overall survival (OS). Although patients with abnormal metaphase cytogenetics have a significantly inferior outcome in terms of event-free and overall survival, the CR rate is similar for patients with and without cytogenetic abnormalities, indicating that CR may not be a good prognostic indicator of ultimate outcome. To address the importance of obtaining a CR for OS, we analyzed our Total Therapy I (VADx3-high dose cyclophosphamide 6g/m2 with stem cell collection-EDAP-melphalan-based tandem transplants-α interferon maintenance) data in those patients who had not received any treatment prior to enrollment (N=155), received at least one transplant (N=135) and were alive one year after the first transplant (N=132). Kaplan-Meier curves were generated using a 1 year landmark to compensate for the guaranteed time of CR patients, but thereby excluding patients who died within the first year after the first autotransplant (N=3). The 1-year landmark was chosen because the large majority of CR patients (75%) had achieved their CR at 1 year after the first transplant. In addition, a time-dependent co-variate analysis for CR was performed, including the 135 patients. The median follow-up of these patients was 10.5 years. The 9 year OS after the landmark, i.e., 10 years after the first transplant, was 41% (95% confidence interval: 26, 55) for CR patients versus 37% (26, 47) for no CR patients (i.e., PR and <PR) with a logrank p value of 0.71 (Figure 1). Using a time-dependent co-variate analysis for CR, achieving a CR was not significantly related to OS (Hazard Ratio: 0.83; p value 0.39). Only the presence of metaphase cytogenetic abnormalities (HR: 2.0; p=0.005), LDH > 190 U/L (upper limit of normal) (HR: 2.0; p=0.01) and CRP >4.0mg/L (HR: 1.6; p=0.03) were significant for OS. When the importance of CR was assessed separately for patients with (N=43) and without (N=84) abnormal cytogenetic (cytogenetic information was missing on 5 patients), no survival benefit for CR patients was seen in either subgroup (p values 0.52 and 0.32, respectively) and similarly, using the time-dependent co-variate analysis for CR, there was no significant benefit for OS of attaining a CR in either group (p value: 0.7 and 0.5, respectively). We conclude that prolonged survival (>10 years) is observed in a substantial proportion of myeloma patients receiving a tandem autotransplant-based regimen, irrespective of the completeness of response to tandem transplants. The inherent genetic features of the myeloma and the impact on the micro-environment of the myeloma cells appear to be more important than the absolute tumor burden reduction accomplished by tandem transplants. Our findings may also be a reflection of the insensitivity of CR as an assessment of remaining tumor burden in myeloma and a new definition of CR may be required. Figure Figure

A sample size of 346 respondents was randomly selected from total population of 3326 from the 4 selected villages on the basis of close proximity. A conceptual framework including dependent variable social development and independent variable tourism development were taken. The data were analyzed through frequency and percentage distribution. Moreover, Chi-square test was applied to know the relationship between dependent and independent variables at bi-variate level. In bi-variate analysis a highly significant (P=0.000) relation was found between CGNP is main source of promoting tourism in Chitral,tourists do any impacts upon local community in terms of increased business activities, local culture is safeguarded despite influx of tourists in the area, tourism produced employment opportunities, and social development. Qualitative data supported the empirical findings, however tourism brings economic opportunities at micro and macro level, but unfortunately CGNP is not as satisfactory regarding generating income since its establishment. The government should ensure to make such polices pertaining to the entrance fee, provides accommodation services on payment to the tourists and to reserve the entrance fee or any other form of taxes to ensure CGNP to spend on self-sustaining basis by ensuring refinement in the procedures as well.

Symmetric elliptical distributions have been intensively used in data modeling and robustness studies. The area of applications was considerably widened after transforming elliptical distributions into the skew elliptical ones that preserve several good properties of the corresponding symmetric distributions and increase possibilities of data modeling. We consider three-parameter p-variate skew t-distribution where p-vector μ is the location parameter, Σ:p×p is the positive definite scale parameter, p-vector α is the skewness or shape parameter, and the number of degrees of freedom ν is fixed. Special attention is paid to the two-parameter distribution when μ=0 that is useful for construction of the skew t-copula. Expressions of the parameters are presented through the moments and parameter estimates are found by the method of moments. Asymptotic normality is established for the estimators of Σ and α. Convergence to the asymptotic distributions is examined in simulation experiments.

Geometric morphology can be influenced by several biotic and abiotic factors, including predator–prey interactions and habitat structure. We measured the external morphology of Micropterus salmoides (largemouth bass, LMB) from two states in north-eastern United States, to assess the potential divergence of body shape. LMB varied in overall body shape (canonical variate analysis, P<0.001) between states, with Maine populations exhibiting shorter jaws (ANOVA, P<0.001) and thicker caudal peduncle depths (ANOVA, P<0.001) than the LMB in Pennsylvania. We propose that these observed differences in morphological traits suggest that jaw length may be influenced by prey availability and resource utilisation, whereas peduncle depth is better explained by surrounding habitat structure. These findings showed that body shape is variable and is influenced by a complex array of environmental factors, even over small latitudinal differences.

21112 Background: The prediction of disease progression in prostate cancer patients following radical prostatectomy (RP) remains problematic. The use of molecular markers could offer a better stratification of patients more at risk of progression. As such, we recently reported that nuclear ErbB3 was associated with Gleason score and hormone-refractory status. The objective of this study was to evaluate whether ErbB3 could predict overall biochemical recurrence (BCR). In addition, we evaluated if three nuclear markers known to be associated with progression (Cyclin D1, Ki67 and androgen receptor) were more significant predictors of BCR than ErbB3 alone or in combination. Methods: Using immunohistochemistry, we analyzed a tissue microarray containing 373 cores from 63 RP specimens. No patient had received hormone therapy prior to surgery and prior to BCR. The quantitative analysis of nuclear staining was measured by two independent observers (ErbB3, Cyclin D1 and AR) or with the ImagePro Plus softwareTM (Ki67). Marker expressions were categorized as either positive or negative according to the median expression. Results: Of the four markers analyzed, Ki67 alone was the strongest predictor of overall BCR. In a multi-variate Cox regression model (backward conditional), while controlling for the pre-operative PSA, Gleason score and lymph node invasion at time of surgery, KI67 was found to be an independent predictor of BCR with a KI67+ patients having lower risk of BCR (HR=-2.51, p=0.015, CI 95%: 1.19–5.29). We then analyzed if different marker combinations could predict BCR. Patients positive for nuclear AR or AR+/Cyclin D1+ double positive were found to have lower risk of BCR (Kaplan-Meier, p=0.047 and p=0.026, respectively). However, in the multi- variate model, the combinations of Cyclin D1+/AR+ (HR=-2.28, p=0.053, CI 95%: 0.94–5.49), ErbB3+/Ki67+ (HR=-2.43, p=0.034, CI 95%: 1.07- 5.52) and AR+/Ki67+ (HR=-2.32, p=0.049, CI 95%: 1.01–5.35) could not improve on the predictive value of KI67 alone. Conclusions: The major new finding of the study is that patients positive for KI67 expression were at a lower risk of developing BCR, which contrast previously published results, and warrants further investigations. No significant financial relationships to disclose.

This study uses Pakistan Social and Living Measurement Survey 2016 to study gender discrimination in school enrollment across the four provinces of Pakistan using bi-variate analysis. Results show that there is highly significant difference between male and female education in rural areas (x^2=4940.50 and p<0.05). Analysis indicate that gender disparity in enrollment is significantly higher in low income households (x^2=115.468 and P<0.05). The study also showed that as compared to male, fewer female are enrolled in both public and private sectors. Hence, socio-economic factors play important role in making decision about children enrollment in different types of school. The study recommends that government to take appropriate steps to reduce gender discrimination in school enrollment by offering subsidy on female education in the country.

Abstract Introduction: Death during induction therapy remains a problem in the management of acute myeloid leukemia (AML). An estimated 6.1% in adult patients and between 19.3% and 27% in subjects of all ages have died of AML during induction therapy. The purpose of this study is to identify the factors that can lead to death during induction therapy. Patient and methods: In this multicenter retrospective study, including the Hematology Services of CHU Tlemcen, EHU of Oran, CHU of Oran, CHU of SBA, EPH of Mascara and HMRU of Oran, from 01/01/2007 to 31/12 / 2017. We have included de novo and secondary AML adult patients and have benefited from conventional chemotherapy (regardless of the type and doses of anthracyclin). However, we have excluded patients with a contraindication to treatment, acute promyelocytic leukemias. The evaluation criterion was the death or the survival during the induction therapy (3 + 7 or 3 + 10 regimens). A variable was considerated statistically significant if the p value was ≤ 0.05. The measurement of a relationship between a possible variable and the occurrence of death was estimated by the Odds-ratio. The associations were evaluated first by a bi-variate analysis followed by a multivariate analysis using logistic regression, including statistically significant variables at the value ≤ 0.1 in bi-variate analysis. If a continuous variable was statistically significant, the receiver operating characteristic curve ROC was constructed. Results: Over the past 11 years, 316 patients were included. These patients received either the 3 + 7 or 3 + 10 regimens. The death rate has been estimated at 11.4% (36 patients). We found that age (p: 0.17), PS ≥2 (p: 0.36), clinical symptoms at diagnosis, secondary AML (p: 0.86), FAB classification, white blood cell count (p: 0.34), anthracyclines doses (Daunorubicin 90 mg / m2 and Doxorubicin 45 mg / m2 VS Daunorubicin 60 mg / m2) and antibiotic prophylaxis (p: 0, 95) do not affect the mortality rate Table 1. In contrast, the creatinin level ≥ 12 mg / dL (p: 0.02), the LDH level> 700 U / L (p: 0.038) and the albumin level ≤ 35 g / L (p: 0.046), increase the risk of death during induction therapy. Table 1 Conclusion: Conventional induction therapy can be used in patients over 60 years of age. On the other hand, renal failure, hypoalbuminemia and elevated LDH levels increase the risk of mortality during induction therapy. Disclosures No relevant conflicts of interest to declare.

Context and Objective: Hemorrhagic Cerebrovascular Accidents represent 10 to 15% of all strokes and are often related to the spontaneous rupture of small vessels weakened by chronic arterial hypertension or amyloid angiopathy. The aim of this work was to study the prognostic determinants of intracerebral haematomas at the neurology department of Conakry University Hospital.
Patients and Method: This was a retrospective analytical study conducted on all patients who were hospitalized with intracerebral hematoma over the 24-month period. Only the records of patients in whom intracerebral hematoma was confirmed by brain imaging were included in this study. Logistic regression (uni-variate and multi-variate) identified prognostic determinants of intracerebral hematoma at p < 0.05. The data were entered using Epi Info software version 7.1.4.0 then analysed using STATA / SE software version 11.2.
Results: This study found 21% of cases of intracerebral hematomas during the study period, with a male predominance of 60% and a sex ratio of 1.50. The study was conducted in the presence of a male patient. Hypertension was the cause found in 89.52% of patients; followed by arteriovenous malformations in 6.67% of patients, 2.86% of cases of amyloid angiopathy and 0.95% of unknown cause. Nevertheless, we still recorded 20% of deaths during hospitalization.
Conclusion: Previous quality of life and co-morbidities also modify the prognosis and should be taken into account in the prediction of disability and future quality of life of patients with intracerebral haematoma.

Category: Ankle, Trauma Introduction/Purpose: Despite an increasing number of elderly individuals undergoing surgical fixation for ankle fractures, few studies have investigated peri-operative outcomes and safety of surgery in an octogenarian and nonagenarian population (age >=80 years). Past literature has shown octogenarians to be a potentially vulnerable population that have drastically different adverse outcomes and higher resource utilization as compared to individuals below the age of 80 years. Methods: The 2012-2017 American College of Surgeons – National Surgical Quality Improvement Program (ACS-NSQIP) was queried using Current Procedural Terminology codes for patients undergoing open reduction internal fixation (ORIF) for isolated uni-malleolar (CPT-27766, CPT-27769, CPT-27792), bi-malleolar (CPT-27814) and tri-malleolar (CPT-27822, CPT-27823) ankle fractures. The study cohort was divided into three distinct groups for comparisons (Age <65 years, Age 65-79 years and Age=>80 years/octogenarians + nonagenarians). Multi-variate regression analyses were used to compare the independent effect of varying age groups on 30-day post-operative outcomes while controlling for differences in baseline clinical characteristics (age, gender, sex, race, fracture type/severity, open vs. closed fracture, admission status, BMI, co-morbidities, functional health status, ASA group and operative time). For comparison purposes, Age<65 years was taken as reference group in multi-variate regression models. Results: A total of 19,585 patients were included – out of which 1,033 (5.3%) were octogenarians/nonagenarians (=>80 years). Following multivariate analysis, individuals aged =>80 years were at a significantly higher risk of 30-day wound complications (OR 1.84; p=0.019), pulmonary complications (OR 3.88; p<0.001), renal complications (OR 1.96; p=0.015), septic complications (OR 3.72; p=0.002), urinary tract infections (OR 2.24; p<0.001), bleeding requiring transfusion (OR 1.90; p=0.025), mortality (OR 7.44; p<0.001), readmissions (OR 1.65; p=0.004) and non-home discharge (OR 13.91; p<0.001). Individuals between the age of 65-79 years only had a higher risk of pulmonary complications (OR 2.30; p=0.004), urinary tract infections (OR 2.24; p<0.001), readmissions (OR 1.41; p=0.005) and non-home discharges (OR 3.55; p<0.001), with the effect sizes being small as compared to age >=80 years group. Conclusion: Based on the findings, it appears that octagenarians and nonagenarians (age =>80) are a fundamentally distinct and vulnerable age group that is at a higher risk of complications, readmissions, mortality and non-home discharges as compared to other geriatric (65-79 years) and non-geriatric (<65 years) patients. Providers should understand the importance of pre-operative counselling and risk-stratification in this vulnerable patient population.

<p>In assembly lines, rework stations are generally used for reprocessing defective items. On the other hand, using rework stations for this purpose only might cause inefficient usage of the resources in this station especially in an assembly line with a low defective rate. In this study, a mixed-integer programming model for cycle time minimization is proposed by considering the use of rework stations for performing parallel tasks. By linearizing the non-linear constraint about parallel tasks using a variate transformation, the model is transformed to a linear-mixed-integer form. In addition to different defective rates, different rework station positions are also considered using the proposed model. The performance of the model is analyzed on several test problems from the related literature<strong><em>.</em></strong></p>

Abstract Purpose: Chromosome 17 abnormalities define a group of patients with acute myelogenous leukemia (AML) (Nahi, H. et al. Leukemia and Lymphoma2008;49:508) with poor outcomes. We analyzed the additional impact of chromosome 17 abnormalities (−17, −17p, −17q, der17) among patients with AML and cytogenetic abnormalities traditionally considered to be of adverse prognosis. Patients and Methods: 1086 patients with AML [excluding inv 16, t (8;21), t (15;17), Diploid/-y abnormality] were included in this analysis. Based on cytogenetic abnormalities patients were grouped into: −5,−7,−5and −7, complex. The following parameters were included in uni and multi-variate analysis: age, performance status, WBC, hemoglobin, platelets, marrow blast percentage, bilirubin, creatinine, albumin, LDH, chromosome 17 abnormality (yes/no). Results: Four hundred and fourteen (45%) patients achieved complete remission (CR) or CR with incomplete platelet recovery (CRp) and 267 (64.5%) patients relapsed. Two hundred seventy (24.9%) patients had abnormalities of chromosome 17. Abnormalities of chromosome 17 were associated with lower CR or CRp rate (p=0.02) and higher possibility of having cytogenetic abnormality of −5 or −7 (p<0.0001). Multivariate analysis showed that patients with abnormalities of chromosome 17 had worse overall survival (OS) compared to patients without (p= 0.003)(Fig.1). Multi-variate analysis within cytogenetic subgroups showed that chromosome 17 abnormalities were associated with worse OS in patients with chromosome 5 abnormality(p=.02) (data not shown) and in those with complex cytogenetics (p=.04)(Fig.2) and not in patients with chromosome 7 (p=.17)or combined 5 and 7 abnormalities (p=.33). Similar analysis restricted to patients achieving CR/CRp after induction therapy showed that impact of chromosome 17 abnormalities on relapse free survival (RFS) mirrored their impact on OS. Conclusion: chromosome 17 abnormalities are associated with worse OS and RFS in patients with AML and adverse cytogenetics and have additional negative impact on the outcomes in certain well-known adverse cytogenetic subgroups.

Background: This study evaluated the association between self-reported adherence with concurrent and subsequent glycemic control amongst type 2 diabetes patients at a tertiary care hospital in Malaysia. Methods: Demographic and clinical variables were assessed at baseline, after three and six months in 73 type 2 diabetes patients. Regression analysis, using SPSS, evaluated the concurrent and longitudinal association of medication adherence and glycemic control. Potential confounders of variables were identified using bi-variate correlation analyses. Results: Concurrent Medication adherence and HbA1c association were significant after adjusting for ethnicity (P = 0.005). For longitudinal observation at 3 months, the association was significant after adjusting for ethnicity (P = 0.016); however, it became non-significant when baseline glycemic control was included in the model (P = 0.28). Conclusion: Easy to administer MALMAS significantly predicted concurrent glycemic control independent of potential confounders. This association persisted in longitudinal observation after 3 months when adjusted for confounders and became non-significant after adjusting for baseline glycemic control.

Suppose we have k independent p-variate normal populations having unknown mean vectors µi and dispersion matrices of the form [Formula: see text]is unknown and Hi is a known p x p positive definite matrix, i = 1, 2, ... k. The investigators in these k populations may possibly have implemented different sequential or multistage sampling methodologies to estimate the mean vectors individually, having certain notions of “fixed-precision” tied with their individual problems of statistical inference. In this paper, we examine how such already available sample resources obtained from independent, but comparable studies can be fruitfully combined in order to provide a “fixed-size” confidence region for a linear combination of the k mean vectors. We discuss appropriate asymptotic second-order characteristics for the coverage probability under a fairly broad set of assumptions on the stopping variables. An example has been included involving purely sequential, accelerated sequential and three-stage sampling techniques.

e15155 Background: HCC is one of the leading causes of cancer deaths worldwide. Despite increasing systemic therapy options for patients with advanced HCC, there are currently no predictive biomarkers to guide therapy selection. Phosphoproteomics has been successfully used to identify accurate predictive biomarkers in other cancers from frozen clinical samples (Dokal et al., 2021 ASCO Annual Meeting). In this study, we test the feasibility of biomarker discovery using phospho- and whole-proteomics analyses on formalin fixed and paraffin embedded (FFPE) tru-cut liver biopsies from patients with HCC. Methods: FFPE tru-cut biopsies (n = 29) were obtained from separate cohorts of 15 HCC patients [tumor (T)] and 14 patients with chronic liver disease with varying levels of cirrhosis, fibrosis or steatosis but without cancer [non-tumor (NT)]. T samples were from advanced HCC patients with varied aetiology (chronic viral hepatitis, alcohol or NAFLD). Proteins were extracted from 10 x 10µm sections; crosslinks reversed before digestion to peptides; and multiple clean-up/enrichment steps before analysis. Peptides were quantified by mass spectrometry and performance assessed using multi-variate and enrichment analyses. Results: Overall, 4978 phosphopeptides and 3721 proteins were quantified across all samples. Multi-variate analyses based on the relative expression of phosphopeptides or proteins showed a clear separation between T and NT samples, as well as phenotype-distinct separation (i.e according to differentiation) within the T group. Subsequent testing also verified that the method could reproducibly measure these HCC-differentiating phosphorylation sites (and proteins). Proteins associated with HCC were regulated as expected in T vs NT, e.g. ASS1 (log2-fold change (FC) = -1.75, p < 0.001), BDH2 (log2-FC = -1.97, p < 0.001). Known drug targets were found to be significantly upregulated in poorly-differentiated HCC, e.g. PARP1 (log2-FC = 1.7, p < 0.001) and AKT1 (log2-FC = 1.5, p < 0.001), as well as previously described phosphorylation sites, e.g. p-CDK1 T14 (log2-FC = 5.95, p = 0.007) and p-MCM2 S139 (log2-FC = 2.98, p = 0.046). Kinase substrate enrichment analysis (Casado et al., Science Signaling 2013) showed increased activity for several kinases in T vs NT, including A-RAF (z-score = 3.2, p < 0.001), MAPK3 (z-score = 2.1, p = 0.022) and TNK2 (z-score = 2.1, p = 0.003). Conclusions: We successfully adapted (phospho-)proteomics to FFPE tru-cut biopsy specimens, enabling reproducible identification of novel and known (phospho-)proteins that distinguished differentiation status. A prospective study utilising this phosphoproteomic analysis pipeline is now underway, recruiting patients with advanced HCC receiving first line standard of care therapy with immune checkpoint inhibitor combinations or tyrosine kinase inhibitors to identify potential predictive biomarkers of response.

Background: The success or failure of public health interventions and advocacies depend largely on the effectiveness of the methods used. Awareness and knowledge are two words that are often used interchangeably in the assessment of contraceptive usage as well as attitude and practice. This study sought to know if the difference between knowledge and awareness does affect usage of contraceptives with the intention of recommending the best option for an improved usage.Methods. A cross sectional study design involving 151 female students of the University of Ilorin was conducted. Trained questionnaire administrators administered the structured questionnaire. The questionnaire was coded and analysed with Statistical Package for Social Sciences version 23, IBM Version. Data were analysed using descriptive and inferential statistics. Comparison of proportions at the bi-variate level was done using Chi-square test while stepwise model of binary logistic regression analysis was done at the multivariate level. Data obtained was also analyzed with EPI info 6.0 and Stata version 5.0 applying t-test, Chi Square and Fisher's exact test statistics. Selection of variables to be imputed into the model was carried out if they were significant at the bi-variate level. Adjusted odds ratio and 95% confidence interval were obtained to identify factors that were significantly predicting the use of contraception among respondents. The level of statistical significance was set at p<0.05.Results. The study showed that awareness did not have significant correlation (p>0.75) with use of contraception despite its high level (91.4%) while knowledge had statistically significant correlation (p=0.005). This was higher among those with good knowledge (68.1%) as compared to those with poor knowledge (43.3%). Islam was significantly associated with use of contraception compared to Christianity (p=0.044). At multivariate level, only good knowledge of contraception remained a significant predictor of use of contraception. Students with good knowledge were three times more likely to use contraception as compared to those with poor knowledge (OR=2.411).Conclusion. Awareness was not found to be significantly associated with contraceptive usage as compared to knowledge. Researchers and public health practitioners need to take full advantage of this finding when promoting health care interventions such as family planning by focusing on educating the students rather than awareness promotion alone.

e20511 Background: Multiple myeloma (MM) is molecularly heterogeneous with many treatment regimens developed targeting different aspects of the disease. Multi-omics studies are now widely available, facilitating a precision medicine approach for personalized MM treatments. However, data from these studies vary with respect to treatment regimens, patient age, disease stage, and genomic alterations, thus complicating identification of treatment effects. Methods: From a Multiple Myeloma Molecular Causal Network (M3CN) model we previously described, we identified a prognostic subnetwork (prognNET) associated with survivals of newly diagnosed MM (NDMM) patients. We derived a network risk score (NRS) for each patient by inferring their molecular state with respect to prognNET, and partitioned patients into NRS low, medium, and high groups (referred as NRSL/M/H). We validated NRSL/M/H to be significantly associated with progression free survival (PFS) and overall survival (OS) in single variate and multi-variate Cox regression models including age and ISS stage in TT2,3,4 and HOVON studies. Results: To determine the impact of NRS in an independent contemporary dataset, we examined NDMM patients with RNAseq data in the MMRF-CoMMpass study. Among young patients (age < 65), ones with combined therapies (CoTs) as the first line therapy (n = 363) had better survival than ones on proteasome inhibitors (PIs) (n = 93) (p = 0.027 and 0.002 for PFS and OS). When stratified by ISS stage and NRS, there was no significant difference between CoTs and PIs except that in the stage I-NRSL group, patients on PIs had better PFS than ones on CoTs (p = 0.016). This suggests that NRS may be able to discriminate ISS stage I patients that do not need CoT. Similarly, we studied the ability of NRS to discriminate patients that benefit from autologous stem cell transplant (ASCT). In a model combining age, ISS stage, NSR, and induction treatment, ASCT was associated with better survival. When stratified young patients on CoTs by ISS stage and NRS, only the stage II-NRSM and stage III-NRSM patients benefited from ASCT in term of PFS (p = 0.01 and 0.005) and OS (p = 0.004 and 0.04). Conclusions: Stage and NRS group should be considered in personalizing treatment options for NDMM patients.

A Comparison of Anthropometry between Ironman Triathletes and Ultra-swimmersWe intended to compare the anthropometry of male and female Ironman triathletes with the anthropometry of male and female ultra-swimmers. Body mass, body mass index and body fat were lower in both male and female triathletes compared to swimmers. Body height and length of limbs were no different between the two groups. In the multi-variate analysis, in male triathletes, body mass (p=0.015) and percent body fat (p=0.0003) were related to race time; percent body fat was also related to the swim split (p=0.0036). In male swimmers, length of the arm was related to race time (p=0.0089). In female triathletes and swimmers, none of the investigated anthropometric variables showed an association with race time. We concluded that Ironman triathletes and ultra-swimmers were different regarding anthropometry and that different anthropometric variables were related to race time. We assume that other factors, such as training and equipment, as opposed to anthropometry, may better predict race time in male and female Ironman triathletes.

<p>This paper contributes to presenting the relationship that exists in a certain tourism destination between the World Heritage Site (WHS) and the Intangible Cultural Heritage (ICH), showing a segmentation of the tourists in Cuenca, Ecuador. The methodology used in this research has been the application of a multivariate technique of grouping items and the realisation of a post-hoc single-variate ANOVA analysis. The results show the existence of three motivational dimensions for visiting the city, two of a cultural nature and the third being hedonic. Depending on the motivation, four types of tourists are identified: the hedonic ICH-WHS tourist, the hedonic WHS tourist, the hedonic tourist and the ICH-WHS tourist. This research reinforces this theme, in a geographic area, Latin America, characterised by a recognised WHS but still little studied in the scientific literature.<strong></strong></p>

In this study, canonical correlation analysis was applied to estimate the relationship between body measurements and carcass traits of 28 male cross bred rabbits of about 12 weeks of age, reared under semi intensive system. Four body measurements, pre-slaughter weight (PSW) , body length (BL), chest circumference (CC), and ear length (EL) as predictor variable while dressing percentage ( DP) , hot carcass weight (HCW) and cold carcass weight (CCW) as criterion variables. Pre-slaughter weight and body length had significant (P<0.001) simple correlation coefficients with the carcass traits except for dressing percentage. The three canonical variate pairs ranged between .99 to .42 and only the first pair was significant (P<0.001). From the analysis pre-slaughter weight and body length can be regarded as the main factors as live measurement traits, while dressing percentage did not have pronounced effect on the emerged criterion variables.
