Abstract:

Introduction: Anemia is a public health problem, prevalent among women of childbearing age. The aim was to determine the frequency of anemia in the first, second and third trimesters of pregnancy and to determine the associating factors in Algerian pregnant women. Methods: We conducted a prospective and longitudinal cohort study of 300 pregnant women from December 2013 to July 2016. All consenting women attending antenatal clinics and having undergone complete blood count (CBC) were included in the study. Sociodemographic characteristics, individual’s obstetrical history and the results of the CBC were collected. Anemia was defined according to the WHO criteria. After some descriptive statistics, we performed a bivariate analysis using the Chi-square test and Fisher exact probability test in order to determine the factors associated with gestational anemia. Results: The rate of anemia was 28.0 % in the first trimester, 32.3 % in the second and 54.2 % in the third one. It was more frequently observed during the third trimester of pregnancy (P < 0.05). No significant difference was found between gestational anemia and socio-demographic factors. Women with inadequate gain were more anemic (p = 0.01). The average concentration of hemoglobin, hematocrit, VGM and platelets were lower in anemic pregnant women (p < 0.0001). Conclusion: The prevalence of anemia during pregnancy remains high. A better management of chronic diseases in pregnant women and of postpartum follow-up is necessary to treat anemia before a subsequent pregnancy.

Abstract:

AbstractTo define metrics of phenotypic aging, it is essential to identify biological and environmental factors that influence the pace of aging. Previous attempts to develop aging metrics were hampered by cross-sectional designs and/or focused on younger populations. In the Baltimore Longitudinal Study of Aging (BLSA), we collected longitudinally across the adult age range a comprehensive list of phenotypes within four domains (body composition, energetics, homeostatic mechanisms and neurodegeneration/neuroplasticity) and functional outcomes. We integrated individual deviations from population trajectories into a global longitudinal phenotypic metric of aging and demonstrate that accelerated longitudinal phenotypic aging is associated with faster physical and cognitive decline, faster accumulation of multimorbidity and shorter survival. These associations are more robust compared with the use of phenotypic and epigenetic measurements at a single time point. Estimation of these metrics required repeated measures of multiple phenotypes over time but may uniquely facilitate the identification of mechanisms driving phenotypic aging and subsequent age-related functional decline.

Abstract:

Since its inception, the intellectual capital (IC) framework, which developed from accounting and financial perspectives, focused primarily on firm-level analysis. There have been several important attempts in the literature to take IC to the macroeconomic level. The purpose of this paper is to assess the relationship between national intellectual capital, proxied with modified National Intellectual Capital Index (NICI) introduced by Bontis [7], and the Human Development Index (HDI), which became an important alternative to the traditional single dimensional measure of a country's development, like the gross domestic product [42]. The paper proposes a modified NICI suggested by Užienė [52]. The analysis includes panel data regression analysis for 12 countries. The dataset incorporated longitudinal data for weighted components of the NICI index for the period of 21 years (2000-2021). The results revealed that each of the elements of NICI, namely National Human Capital (NHC), National Market Capital (NMC), National Process Capital (NPC), and National Renewal Capital (NRC), exhibits significant impact on the levels of HDI in the said period. However, all elements, apart from NRC, show significant positive impact on HDI, pointing to the conclusion that these factors represent an important foundation for achieving and maintaining national competitiveness. Contrariwise, NRC was revealed to have the significant negative impact on HDI, opening the door to the question whether NRC is a real driver of national development, or just the effect of already reached development level.

Abstract:

Objective.To assess disability in systemic sclerosis (SSc) longitudinally and to identify disease-specific determinants, after accounting for informative patient dropout.Methods.We performed a multicenter, longitudinal study of 745 patients with SSc followed in the Canadian Scleroderma Research Group registry. Disability was assessed using the Health Assessment Questionnaire (HAQ). Longitudinal changes in disability were modeled using statistical approaches accounting for various levels of patient dropout.Results.In all the models, disability in SSc worsened over time. The magnitude of the worsening was small when patient dropout was assumed to be completely at random (increase in the HAQ of 0.022, 95% CI 0.002–0.042, per year). After accounting for different levels of informative patient dropout, the increase in the HAQ ranged from 0.039 (95% CI 0.018–0.061) per year to 0.071 (95% CI 0.048–0.094) per year. Thus, using the most conservative of these estimates, this was equivalent to an increase in the HAQ of 0.12 over 3 years. The disease correlates found to be most closely associated with disability were diffuse disease and breathing problems.Conclusion.Our study provides strong evidence that SSc causes increased disability over time, with breathing problems and disease type being the strongest predictors of disability. Statistical modeling accounting for informative patient dropout is necessary to properly assess the outcomes of patients followed longitudinally.

Abstract:

El desarrollo multilingüe, ¿refuerza u obstruye el éxito educativo? Esta fue la pregunta inicial del proyecto de investigación “Desarrollo multilingüe - una perspectiva longitudinal” que se presenta en este artículo. Si bien el multilingüismo se ha citado a menudo como una desventaja, también hay indicios de que favorece el éxito del aprendizaje (de idiomas). Por consiguiente, uno de los objetivos del proyecto fue obtener información primaria sobre el desarrollo lingüístico de los alumnos de escuelas secundarias multilingües en Alemania, a fin de contribuir a aclarar más esta cuestión. El proyecto se basa en datos de competencias lingüísticas receptivas (lectura) y productivas (escritura) en alemán (el idioma de escolarización), ruso y turco como idiomas de herencia de los inmigrantes, inglés (el primer idioma extranjero que se enseña desde la escuela primaria) y, para una parte de la muestra, francés o ruso (como segundos idiomas extranjeros que se enseñan en las escuelas secundarias de carácter académico). Con esta variedad, fue posible examinar los perfiles lingüísticos de los participantes, así como las influencias recíprocas entre los idiomas. La muestra incluyó alrededor de 2.000 estudiantes, a los que se pasó una prueba en cuatro momentos a lo largo del curso escolar. Esta investigación constituye el primer estudio interdisciplinario en todo el mundo que incluye la complejidad del desarrollo multilingüe con una muestra sustancial de encuestados, que midió los datos lingüísticos una amplia gama de datos de contexto para el control estadístico de los factores contextuales que pudieran influir. De ese modo, el proyecto crea nuevos conocimientos sobre la complejidad del desarrollo lingüístico en el contexto de la migración, así como una nueva base para la concepción de la enseñanza de idiomas en escuelas lingüísticamente heterogéneas. En esta contribución nos centramos en uno de los principales resultados de nuestro proyecto: la elaboración de una prueba innovadora para la medición de las aptitudes de escritura multilingüe Does multilingual development bolster or obstruct educational success? This was the starting question for the research project “Multilingual Development - a Longitudinal Perspective” that will be presented here. While multilingualism has often been cited as a disadvantage, there are also indications that it supports successful (language) learning. It was therefore a goal of the project to obtain primary information on the language development of multilingual secondary school pupils in Germany in order to contribute to the further clarification of this question. The project is based on data of receptive (reading) and productive (writing) language skills in German (the language of schooling), Russian and Turkish as immigrants’ heritage languages, English (the first foreign language taught in primary school already) and for a part of the sample French or Russian (as second foreign languages taught in academic track schools). With this range, it was possible to examine the linguistic profiles of the participants as well as reciprocal influences between languages. The sample included roughly 2000 students, tested at four measurement points in the course of secondary schooling. This is the first interdisciplinary study worldwide which includes the complexity of multilingual development on the basis of a substantial sample of respondents, measured language data a wide range of background data for statistical control of influencing background factors. The project thereby creates new knowledge about the complexity of language development in the context of migration, as well as a new basis for the design of language education in linguistically heterogeneous schools. In this contribution, we focus on one of the premier outcomes of our project: the development of an innovative test for the measurement of multilingual writing skills.

Abstract:

BackgroundSome studies suggest that cannabis use is associated with suicidal ideation, but no detailed longitudinal study has examined suicide as an outcome.AimsTo examine the association between cannabis use and completed suicide.MethodA longitudinal study investigated 50 087 men conscripted for Swedish military service, with cannabis use measured non-anonymously at conscription. Suicides during 33 years of follow-up were identified by linkage with the National Cause of Death Register.ResultsThere were 600 (1.2% of cohort) suicides or deaths from undetermined causes. Cannabis use was associated with an increased risk of suicide (crude OR for ‘ever use’ 1.62, 95% CI 1.28–2.07), but this association was eliminated after adjustment for confounding (adjusted OR = 0.88, 95% CI 0.65–1.20).ConclusionsAlthough there was a strong association between cannabis use and suicide, this was explained by markers of psychological and behavioural problems. These results suggest that cannabis use is unlikely to have a strong effect on risk of completed suicide, either directly or as a consequence of mental health problems secondary to its use.

Abstract:

Human identification by fingerprints is based on the fundamental premise that ridge patterns from distinct fingers are different (uniqueness) and a fingerprint pattern does not change over time (persistence). Although the uniqueness of fingerprints has been investigated by developing statistical models to estimate the probability of error in comparing two random samples of fingerprints, the persistence of fingerprints has remained a general belief based on only a few case studies. In this study, fingerprint match (similarity) scores are analyzed by multilevel statistical models with covariates such as time interval between two fingerprints in comparison, subject’s age, and fingerprint image quality. Longitudinal fingerprint records of 15,597 subjects are sampled from an operational fingerprint database such that each individual has at least five 10-print records over a minimum time span of 5 y. In regard to the persistence of fingerprints, the longitudinal analysis on a single (right index) finger demonstrates that (i) genuine match scores tend to significantly decrease when time interval between two fingerprints in comparison increases, whereas the change in impostor match scores is negligible; and (ii) fingerprint recognition accuracy at operational settings, nevertheless, tends to be stable as the time interval increases up to 12 y, the maximum time span in the dataset. However, the uncertainty of temporal stability of fingerprint recognition accuracy becomes substantially large if either of the two fingerprints being compared is of poor quality. The conclusions drawn from 10-finger fusion analysis coincide with the conclusions from single-finger analysis.

Abstract:

BackgroundThe source of variability in people's response to stressful life events is poorly understood.AimsWe examine the genetic and environmental underpinning of resilience (i.e. the difference between the twins' internalising symptoms and their predicted symptoms based on cumulative stressful life events).MethodStressful life event exposure and internalising symptoms were assessed at two time points in 7500 adult twins. Using the residual between actual and predicted internalising symptom total score, twin modelling was conducted for each wave separately and longitudinally.ResultsResilience was found to have a moderate genetic heritability at each wave (~31%). Qualitative gender effects were found. Incorporating error of measurement into the model increased the estimated heritability for the latent construct of resilience (~50%). When measurement error and occasion-specific effects were removed, environmental influences contributed roughly equally to level of resilience.ConclusionsBoth genes and environment influence level of psychiatric resilience, and are largely stable over time. Environmental influences can have an enduring effect on resilience.

Abstract:

Abstract Background: Pubertal growth data in Thai children has been reported as cross-sectional studies. There is no longitudinal study in Thai children. Objective: Investigate the longitudinal growth data in normal Thai children including the relationship between age at pubertal onset and other growth parameters. Material and method: Eighty-eight normal children (44 boys, 44 girls) were longitudinally assessed for the growth and puberty until they reached their final adult height. Pubertal staging was assessed by the Tanner method. Results: Mean age of pubertal onset was 10.2 ± 1.2 years for girls and 12.2 ± 1.0 years for boys. Total pubertal height gain was 18.3 ± 4.0 cm for girls and 22.3 ± 4.4 cm for boys. Total pubertal height gain had a negative correlation with age at pubertal onset for girls, but not for boys. Conclusion: The onset of puberty was not much changed from previous studies. Girls with early puberty had a higher pubertal height gain. This might be due to a compensatory mechanism. These longitudinal growth data can be used as a reference in clinical practices for Thai children.

Abstract:

Abstract This study examined the association between the two dimensions of social capital, structural and cognitive, and depression, as well as investigating their within- and between-effects. Using the Wisconsin Longitudinal Study, I applied a multi-level 2-wave longitudinal analysis, over a 7-year period, to examine these two dimensions of social capital influence on individual’s depressive symptoms at both the between- and within person levels. Results suggest both dimensions of social capital are negatively related with levels of depressive symptoms for individuals. The within-person changes for both self-efficacy and sense of belonging were larger than the estimates of between-effects, while trust and structural social capital effects were equal. These findings add to the growing body of literature examining depressive symptoms in late life, while also providing evidence for policymakers to hone in on key areas that can address depressive symptoms with social capital interventions.

Abstract:

When evaluating the effectiveness of study abroad programs, students overwhelmingly report that they continue to develop their self-confidence and world view as a result of their study abroad experience once they return home. This article presents a study that uses the intercultural development inventory (IDI) to address whether or not students' cultural learning continued to improve four months after returning from their study abroad experience.

Abstract:

In this paper, we introduced a bamboo longitudinal flattening technology and analyzed the effects of the softening–flattening process on the physical and mechanical properties of moso bamboo. This is a newer bamboo processing technology that can enhance the utilization and reduce pollution compared with traditional bamboo-based products. Results showed that the parenchyma cells distorted and compacted due to the flattening process. The hemicellulose and cellulose content decreased, while the content of lignin presented an increasing tendency. As expected, the dimensional stability of moso bamboo enhanced due to the decrement of hemicellulose. The softening–flattening process positively contributed to the micro-mechanical properties of treated bamboo specimens. For example, the hardness and modulus of elasticity of the untreated bamboo sample increased from 0.58 and 15.7 GPa to 0.8 and 17.5 GPa, respectively. In addition, the changes in cellulose crystallinity and mechanical properties were also investigated in this paper. The cellulose crystallinity increased from 37.5% to 43.2%, significantly. However, the modulus of rupture of the flattened bamboo board decreased from 9000 to 7500 MPa due to the grooves made by the flattening roller. The MOE of flattening bamboo board showed the same decreasing tendency.
