L'utilisation des soins prénataux chez les migrants sans assurance maladie à Montréal

Objectif : Des recherches antérieures ont identifié une mauvaise utilisation des soins prénataux chez les migrants sans assurance maladie au Canada. Cependant, les facteurs qui influencent cette utilisation restent largement inexplorés. L'objectif de cette étude était de quantifier l'utilisation des soins prénataux dans ce groupe et d'identifier les barrières et les facteurs facilitant l'utilisation des soins prénataux. Méthodes : Une étude transversale sur les migrants sans assurance maladie à Montréal, Canada, a été menée entre janvier 2016 et août 2017. Les participants ont été recrutés dans une clinique bénévole locale et dans la communauté en utilisant un échantillonnage à partir de lieux et en boule de neige. Les mesures des résultats comprenaient l'utilisation des soins prénataux, l'initiation des soins prénataux et l'adéquation des soins prénataux. L'analyse de régression a identifié les barrières et les facteurs facilitant l'utilisation des soins prénataux. Résultats : 125 grossesses antérieures au Canada ont été recensées parmi 101 femmes. 65.0% des grossesses impliquaient une utilisation des soins prénataux et 44.6% impliquaient un début tôt des soins. Parmi les 62 grossesses menées à terme, 29.5% ont reçu des soins prénataux adéquats. Les femmes ≥35 ans (OR 0.13, IC à 95%: 0.03-0.54, p = 0.01), entre 18 et 24 ans (OR 0.30, IC à 95%: 0.09-0.99, p=0.049), et celles qui ne savaient pas où consulter (OR 0.25, IC à 95%: 0.06-0.99, p=0.049) avaient significativement moins de chances (p <0.05) d’utiliser les soins prénataux. Les femmes âgées de 30 à 34 ans (OR 0.27, IC à 95%: 0.10-0.72, p=0.01) avaient significativement moins de chances (p <0.05) de commencer tôt les soins prénataux. En revanche, les femmes mariées ou en union de fait (OR 3.16, IC à 95%: 1.04-9.62, p=0.04) avaient significativement plus de chances (p <0.05) de commencer tôt les soins prénataux. Conclusion : Notre étude a révélé que l'utilisation des soins prénataux chez les migrants sans assurance était très faible. Les facteurs influençant l'utilisation des soins prénatals étaient variés et liés à la démographie, au réseau social et à la migration. Les politiques futures devraient viser à améliorer l'accès aux soins prénatals au sein de cette population vulnérable.Objective: Previous research has identified poor prenatal care use among uninsured migrants in Canada, however, the factors influencing this usage remain largely unexplored. The study objective was to quantify the use of prenatal care among this group and to identify the barriers and facilitating factors to prenatal care use. Methods: A cross-sectional survey of uninsured migrants in Montreal, Canada was carried out between January 2016 and August 2017. Participants were recruited from a local volunteer clinic and from the community using venue-based and snowball sampling. Outcome measures included prenatal care use, prenatal care initiation, and prenatal care adequacy. Regression analysis identified barriers and facilitating factors to prenatal care use. Results: 125 previous pregnancies in Canada were identified among 101 women. 65.0% of pregnancies involved prenatal care use and 44.6% involved an early initiation of care. Among the 62 pregnancies carried to term, 29.5% received adequate prenatal care. Women ≥35 years of age (OR 0.13, 95% CI: 0.03-0.54, p=0.01), between the ages of 18-24 (OR 0.30, 95% CI: 0.09-0.99, p=0.049), and those who did not know where to consult (OR 0.25, 95% CI: 0.06-0.99, p=0.049) were significantly less likely (p<0.05) to use prenatal care. Women aged 30-34 (OR 0.27, 95% CI: 0.10-0.72, p=0.01) were significantly less likely (p<0.05) to initiate prenatal care early. In contrast, women who were married or in common-law relationships (OR 3.16, 95% CI: 1.04-9.62, p=0.04) were significantly more likely (p<0.05) to initiate prenatal care early. Conclusion: Our study found that prenatal care use among uninsured migrants was very poor. Factors influencing prenatal care use were varied and related to demographics, social network, and migration. Future policy should aim to improve access to prenatal care among this vulnerable population

Micro-entrepreneurship and subjective well-being: Evidence from rural Bangladesh

© 2019 The Authors Microcredit has long been hailed as a powerful tool to promote livelihoods and reduce poverty through entrepreneurship. However, its impacts on people's subjective well-being remain underexplored. We present a unified theoretical framework for analyzing the effect of microcredit-enabled entrepreneurship on overall life satisfaction – a key manifestation of subjective well-being. Empirically, we apply an instrumental variable approach to a unique census-like household survey conducted in three villages of Bangladesh in 2013. In spite of having no direct effects, we find that microcredit borrowing has an indirect negative effect on overall life satisfaction, through increased worry. On a positive note, we find that female micro-borrowers experience an increase in satisfaction with financial security and achievement in life. We also provide evidence that micro-borrowers with higher levels of assets experience an increase in satisfaction with financial security

Framework and Development of a Collaborative Supply Chain Model

One of the most critical issues of inventory management is Customer demand (intermittent demand, request for change in product, process or phase in / out). Variation in demand increases the difficulty of determining the precise amount of inventory both to avoid stockout and to satisfy the customer fill rate. The inventory control problem is getting complicated by the fact that demand is uncertain or the variation of demand is highly volatile. [1]. Many practical systems such as manufacturing and inventory systems applications are mostly used to model categorical data sequences. [2]. Results indicate that firms that focus on flexibility, quality, and delivery should develop strategic collaboration with suppliers & customers to achieve market and innovation improvement. Cost- and quality-focused firms should develop operational collaboration to achieve resource efficiency. The model allows understanding the right alignment of external suppliers and customers being pursued to for key performance development and continuous improvement insight

A Systematic Review of the Possibility of Determining Age Based on DNA Methylation of the ELOVL2 Gene in Human Samples

Background: In forensic medicine, predicting the age of a victim or suspect can be a clue to solving a crime. Epigenetics has recently played a vital role in age prediction in forensic medicine. Cytosine methylation at cytosine and guanine separated by phosphate (CpG) sites is well recognized as a novel epigenetic marker for age estimation. This study aimed to summarize the information obtained from previous studies to determine age by evaluating DNA methylation in the ELOVL2 gene.Methods: In this systematic review, all related articles published between 2012 and 2022 were extracted by searching reputable scientific databases, such as ISI Web of Science, Science Direct, PubMed, and Scopus. After selecting the appropriate articles, the full text of the articles was prepared and fully evaluated by the researchers. The protocol of this study was carried out based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement.Results: Out of 307 articles, 5 articles were eligible for review according to the study protocol. The strongest correlation between DNA methylation and age was observed at sites 11044644 and 11044634 on chromosome 6 in the living cases. The relationship between the chronological age and the age calculated through DNA methylation was above 90% with an approximate error ranging from 7.5 to 10.4. However, the relationship between the chronological age and the age calculated through DNA methylation was above 90% in the multivariate analysis of sites 11044624 and 11044634 on chromosome 6. In this case, the calculation error reached approximately 6.9 years. Hence, considering a combination of multiple cytosine and guanine separated by phosphate (CpG) sites improves the calculation accuracy and reduces the error percentage. The relationships between DNA methylation and the age at sites 11044880 and 11044640 on chromosome 6 were significantly less reported in the blood samples taken from the dead and in those taken from the living (nearly 64%–78.5%).Conclusion: The results of this study indicated that DNA methylation in the ELOVL2 gene could help predict a person’s biological age

The Value of Foramen Magnum Diameters for Gender Identification Among Iranian Population

Background: By assessing the size of the foramen magnum, it is possible to distinguish two genders, as well as the intergenerational interdependence of the affected individuals. The present study aimed at assessing the value of diameters of foramen magnum for gender identification among the Iranian population.Methods: This analytical comparative cross-sectional study was performed on 200 Iranian cadavers (100 men and 100 women) referred to Kahrizak Autopsy Hall in Tehran between 2017 and 2018. In each case, the foramen magnum was measured by observation and its parameters were measured in a longitudinal anteroposterior and transverse diameter, using a calibrated caliper.Results: The Mean±SD anterior-posterior diameter of the foramen magnum in men and women were 35.59±0.49 mm and 33.90±1.07 mm, respectively, which was significantly higher in men (P&lt;0.001). Similarly, the Mean±SD transverse diameter of the foramen magnum in males and females was 29.49±0.56 mm and 28.5±0.50 mm, respectively, which was significantly higher in men (P&lt;0.001). Based on the area analysis under the Receiver Operating Characteristic (ROC) curve, the anterior-posterior and transverse diameters of the foramen magnum had a high value in the differentiation of the male and female genders (AUC=0.953 and 0.896, respectively, P&lt;0.001). The Mean±SD foramen magnum index in men and women was 84.15±3.02 and 82.87±1.95, respectively, which had a significant difference between the two genders.Conclusion: Given that the anterior-posterior and transverse diameters of the foramen magnum in Iranian men are far more than Iranian women, these diameters can be used to distinguish between the two genders in the precise legal field

Effectiveness of Exterior-Beam Rotation-Prevention Systems for Bridge Deck Construction—Phase II

During bridge deck construction, construction loads are transferred through the overhang-formwork system into the girder system, resulting in significant torsional moments acting on the exterior girder. In some cases, these torsional moments can lead to excessive exterior-girder rotation, thin bridge decks, and cause potential safety and maintenance issues for the bridge. To resist these torsional moments, temporary rotation-prevention systems are commonly used during deck construction. The Illinois Department of Transportation (IDOT) recommended a new rotation-prevention system, which uses a transverse tie combined with a diagonal pipe to limit exterior-girder rotation. This system has been evaluated and validated to be effective, and efficient, based on the finite-element (FE) analysis in Phase I of this research project. In this study, the transverse tie–diagonal pipe system was evaluated through field instrumentation and FE analysis. Also, additional FE analysis was conducted to assess the effects of various parameters of this system, such as the dimensions of the members of this system, protective rubber at the end of pipes, and depth of connecting plates between the diaphragms and girders. Based on the results from this research, it is suggested that larger sections of ties and pipes should be used to ensure the stiffness of the temporary bracing system; and the protective rubber should be eliminated. Furthermore, a maximum ratio of unbraced length to girder depth (B/D ratio) of 4 is recommended when considering the effects of the diaphragm-to-girder connection.IDOT-R27-179Ope

Introducing a Linear Empirical Correlation for Predicting the Mass Heat Capacity of Biomaterials

This study correlated biomass heat capacity (Cp) with the chemistry (sulfur and ash content), crystallinity index, and temperature of various samples. A five-parameter linear correlation predicted 576 biomass Cp samples from four different origins with the absolute average relative deviation (AARD%) of ~1.1%. The proportional reduction in error (REE) approved that ash and sulfur contents only enlarge the correlation and have little effect on the accuracy. Furthermore, the REE showed that the temperature effect on biomass heat capacity was stronger than on the crystallinity index. Consequently, a new three-parameter correlation utilizing crystallinity index and temperature was developed. This model was more straightforward than the five-parameter correlation and provided better predictions (AARD = 0.98%). The proposed three-parameter correlation predicted the heat capacity of four different biomass classes with residual errors between −0.02 to 0.02 J/g∙K. The literature related biomass Cp to temperature using quadratic and linear correlations, and ignored the effect of the chemistry of the samples. These quadratic and linear correlations predicted the biomass Cp of the available database with an AARD of 39.19% and 1.29%, respectively. Our proposed model was the first work incorporating sample chemistry in biomass Cp estimation. View Full-Tex
