Published: October 2020

The assessment instrument is an important component needed in the learning assessment process. However, in practice, there are still many teachers who have not been able to produce quality assessment instruments. The purpose of this study was to produce valid and reliable assessment instruments for social attitudes and social studies learning outcomes in class V on theme of lingkungan sekitar kita. In this study using a 4D development model, namely define, design, develop, disseminate. In this development research, it is only up to the development stage. The instrument used for the assessment of social attitudes was a questionnaire (questionnaire), while for the assessment of social studies learning outcomes used was a multiple-choice test. The data obtained would be analyzed the validity and reliability of each assessment instrument. The results of the analysis of the validity of the social attitude assessment instrument and social studies learning outcomes obtained an average value of 1, which means that the two assessment instruments have very high validity, while the results of the analysis of the reliability of the social attitude assessment instrument are 0,89 and the reliability of the social studies learning outcomes assessment instrument is 0,89. 0,85 which means that these two instruments have a high level of reliability. From these results, it can be concluded that the development of an assessment instrument for social attitudes and social studies learning outcomes is feasible to use in assessing students.
Biochar addition affected nutrient leaching and litter decomposition rates in boreal sandy soils
Authors: Saarnio Sanna , Kettunen Riitta
Published: October 2020

Effects of biochar addition on litter decomposition rates, nutrient leaching and soil moisture were tested in two boreal agricultural soils; a sandy till and a medium fine sand. Three litter bags were buried in soil basins, which were stored in the dark for 31 and 19 weeks in the sandy till experiment and medium fine sand experiment, respectively. Once per each temperature period, the soil was saturated in order to collect excess water for nutrient analyses. Biochar increased the decomposition rate of N-rich litter but did not affect the decomposition of N-poor litter. PO43--P and NO2--N were released from the biochar to the leached water and thus leaching of PO43--P, NO2--N and total P was increased in the soil with the finer texture. However, biochar retained water after heavy irrigation and leaching of PO43--P and total P was not increased on the coarser soil. Although pure biochar adsorbed NH4+-N from nutrient solutions, NH4+-N leaching from both soil types was generally not affected by biochar. Leaching of nitrate NO3--N and total N was decreased on both soils due to retention by the biochar.

Published: October 2020

This study aims to determine optimal sowing date for winter wheat (Triticum aestivum L.) and invoke DSSAT Nwheat model to analyze impact of modified sowing date to phenological development and grain yield. Wheat was grown for three seasons in two locations across Lithuania and sowing was carried out one time per week from 1 September to 29 September. Average three-year temperature of vegetation period gets lower every week by 0.16 °C, and available GDD by 94.5 °C when sowing time is delayed. Modeling results showed that tillering rate is affected by sowing time winter wheat grew 232 (tillers m-2) less with each week of delayed sowing. Grain filling stage was shortened by 1.25 days with each delayed sowing week. Depending on sowing time yield varied from 8.58 t ha-1 to 6 t ha-1 while simulated harvest was 8% lower. We conclude that best winter wheat sowing time for current climatic conditions in Lithuania is mid-September and DSSAT model proves as a useful tool in anticipating sowing time while facing problems caused by a climate change.

Published: October 2020

Carefully coordinated interaction between the endometrium and embryo is critical for the establishment and maintenance of pregnancy in mammals. By exploring the gene expression dynamics of this tissue during preimplantation development, we may be able to get insight into the genetic mechanisms of reproduction during early pregnancy. Here, we have performed comparative transcriptome profiling of the endometrium in response to spherical (Day 7 to Day 12) and elongated (Day 13 to Day 17) embryos in Finnsheep, Texel and their F1 crosses using RNA sequencing (RNA-seq) approach. A total of 21125 genes were expressed in our dataset of which 554 were significantly (absolute log2 fold change > 2.5; adjusted p-value < 0.01) upregulated in the endometrium with elongated embryos. Highly abundant autosomal genes in the endometrium were associated with biological processes such as facilitation of maternal recognition of pregnancy, trophoblast elongation and implantation (LGALS15, CST3, CST6, and EEF1A1). Several endogenous retroviruses (ERVs) including a novel ERV gene located in a reduced FecL locus potentially associated with sheep prolificacy were expressed in our dataset. Comparative transcriptome profiling of the endometrium having spherical and elongated embryos revealed distinct gene expression patterns. Genes that were upregulated in response to elongated embryos indicated the importance of immune system at the maternal-embryo interface prior to implantation.

Published: October 2020

The presence of heavy metals in waters can be sourced from mining, household, agricultural waste and industrial wastes. Some heavy metals are toxic such as Cu, Hg, and Pb can accumulate in aquatic sediments. Sediments that are contaminated with heavy metals will endanger the organisms that live in them. This research aims to identify the concentrations of heavy metals Cu, Hg, and Pb in sediments in the Batang Ayumi River. This research uses a descriptive exploratory method by conducting a survey in advance. Determination of sampling locations using purposive sampling method at four determined stations. This research uses an Atomic Absorption Spectrophotometer. Data analysis was performed by comparing the test result data with the quality standards issued by the IADC / CEDA. The test results show that the concentration of Cu, Hg and Pb in the sediment has a value smaller than the target level value, so the substance in the sediment is not too dangerous for the environment.
Étude sur la participation à la mammographie de dépistage et sur son utilisation au Canada
Authors: Doyle GP , Major D , Chu C , Stankiewicz A , Harrison ML , Pogany L , Mai VM , Onysko J
Published: October 2020

Introduction

Le taux de participation est un indicateur important de l’efficacité d’un programme de dépistage; cependant, la méthode actuellement utilisée pour mesurer le taux de participation au Canada ne permet pas d’établir des comparaisons avec les autres pays. Cette étude vise à évaluer la méthode utilisée pour mesurer la participation à la mammographie de dépistage au Canada, à comparer les méthodes utilisées à l’échelle internationale et à proposer d’autres méthodes.

Méthodologie

Les données des programmes canadiens de dépistage du cancer du sein sur les femmes âgées de 50 à 69 ans ayant subi un examen de dépistage entre 2004 et 2006 ont été extraites de la Base de données canadienne sur le dépistage du cancer du sein (BDCDCS). Les données sur les mammographies effectuées par des médecins rémunérés à l’acte (mammographies de dépistage opportunistes) ont été fournies par les ministères provinciaux de la Santé. Les taux de participation aux programmes de mammographie de dépistage et les taux d’utilisation à des intervalles de 24 et de 30 mois ont été examinés.

Résultats

Au Canada, le taux de participation aux programmes de dépistage s’élève à 39,4 % selon un intervalle de 24 mois, et il est de 43,6 % lorsque l’intervalle est fixé à 30 mois. Toujours au Canada, le taux d’utilisation de la mammographie s’élève à 63,1 % selon un intervalle de 24 mois; il passe à 70,4 % lorsque l’intervalle est de 30 mois.

Conclusion

Compte tenu des différences dans la prestation des services de santé d’une province canadienne à une autre, il faudrait surveiller tant la participation aux programmes que le taux d’utilisation global de la mammographie selon des intervalles de 24 et de 30 mois.
Évaluation des associations de facteurs de risque de dépression de l’Enquête nationale sur la santé de la population : une étude de simulation évaluant la vulnérabilité au biais
Authors: Patten S.B.
Published: October 2020

Contexte

Au Canada, l’Enquête nationale sur la santé de la population (ENSP) est la principale source de données longitudinales sur l’épidémiologie des épisodes de dépression majeure (EDM). Cependant, le moment auquel les interviews sont réalisées pourrait soulever des doutes sur la qualité des estimations fournies par l’ENSP. Plus précisément, l’interview effectuée dans le cadre de l’ENSP vise à évaluer les EDM survenus au cours de l’année qui a précédé l’interview, alors que les interviews sont réalisées à deux ans d’intervalle. La présente étude visait à déterminer si l’on doit s’attendre à ce que cet aspect de l’ENSP introduise un biais dans les estimations longitudinales des associations de facteurs de risque.

Méthodologie

Un modèle de simulation a été utilisé pour représenter l’épidémiologie de base et les résultats attendus d’une étude adoptant l’approche de l’ENSP en matière d’évaluation des EDM. Ce modèle a servi à analyser l’ampleur de la distorsion des estimations qui en découle pour divers rapports des risques instantanés sous‑jacents.

Résultats

Les simulations ont révélé que le moment des interviews de l’ENSP et la période visée par ces interviews sur la dépression semblent ne pas introduire de biais important. Le modèle semblait indiquer que l’incidence serait sous‑estimée en raison des épisodes non recensés, mais qu’aucune distorsion importante des estimations des associations n’en découlerait.

Conclusion

Le moment auquel ont lieu les interviews de l’ENSP ne devrait pas fausser les estimations du risque relatif. Il se peut, bien entendu, que les estimations de l’ENSP soient minées par d’autres sources de biais.
Application of a national administrative case definition for the identification of pre-existing diabetes mellitus in pregnancy
Authors: Allen V.M. , Dodds L. , Spencer A. , Cummings E.A. , MacDonald N. , Kephart G.
Published: October 2020

Introduction

Accurate ascertainment of pregnant women with pre-existing diabetes allows for the comprehensive surveillance of maternal and neonatal outcomes associated with this chronic disease.

Methods

To determine the accuracy of case definitions for pre-existing diabetes mellitus when applied to a pregnant population, a cohort of women who were pregnant in Nova Scotia, Canada, between 1991 and 2003 was obtained from a population-based provincial perinatal database, the Nova Scotia Atlee Perinatal Database (NSAPD). Person-level data from administrative databases using hospital discharge abstract data and outpatient physician services data were linked to this cohort. Various algorithms for defining diabetes mellitus from the administrative data, including the algorithm suggested by the National Diabetes Surveillance System (NDSS), were compared to a reference standard definition from the NSAPD.

Results

Validation of the NDSS case definition applied to this pregnant population demonstrated a sensitivity of 87% and a positive predictive value (PPV) of 66.4%. Use of ICD-9 and ICD-10 diagnostic codes among hospitalizations with diabetes mellitus in pregnancy showed important increases in sensitivity and PPV, especially for those pregnancies delivered in tertiary centres. In this population, pregnancy-related administrative data from the hospitalization database alone appear to be a more accurate data source for identifying pre-existing diabetes than applying the NDSS case definition, particularly when pregnant women are delivered in a tertiary hospital.

Conclusion

Although the NDSS definition of diabetes performs reasonably well compared to a reference standard definition of diabetes, using this definition for evaluating maternal and perinatal outcomes associated with diabetes in pregnancy will result in a certain degree of misclassification and, therefore, biased estimates of outcomes.
Divergent associations between incident hypertension and deprivation based on different sources of case identification
Authors: Aubé-Maurice J. , Rochette L. , Blais C.
Published: October 2020

Introduction

Studies suggest that hypertension is more prevalent in the most deprived. Our objective was to examine the association between incident hypertension and deprivation in Quebec based on different modes of case identification, using two administrative databases.

Methods

We identified new incident cases of hypertension in 2006/2007 in the population aged 20 years plus. Socio-economic status was determined using a material and social deprivation index. Negative binomial regression analyses were carried out to examine the association between incident hypertension and deprivation, adjusting for several covariates.

Results

We found a positive and statistically significant association between material deprivation and incident hypertension in women, irrespective of the identifying database. Using the hospitalization database, the incidence of hypertension increased for both sexes as deprivation increased, except for social deprivation in women. However, whether using the physician billing database or the validated definition of hypertension obtained by combining data from the two databases, the incidence of hypertension decreased overall as deprivation increased.

Conclusion

Associations between hypertension and deprivation differ based on the database used: they are generally positively associated with the hospitalization database and inversely with the standard definition and the physician billing database, which suggests a consultation bias in favour of the most socio-economically advantaged.
Connaissances et perception des entraîneurs au sujet de la consommation de tabac à chiquer chez les jeunes athlètes : résultats d'un sondage réalisé en 2009 en Ontario
Authors: Skinner J.H.C. , Bobbili S.J.
Published: October 2020

Introduction

Les professionnels de la santé publique se préoccupent de la progression de la consommation de tabac à chiquer (TC) par les athlètes. On dispose toutefois de peu de données sur la situation au Canada, notamment chez les jeunes.

Méthodologie

La coalition Pas aux jeunes et la Coaches Association of Ontario ont effectué un sondage auprès des entraîneurs afin d'évaluer, d'une part, le degré de connaissance et de sensibilisation de ces derniers au sujet du TC et, d'autre part, la perception qu'ont ces derniers du rôle que peut jouer l'entraîneur pour influencer la consommation de TC chez les athlètes qu'ils encadrent. Les sondages ont été acheminés par voie électronique à des entraîneurs encadrant des garçons et des filles âgés de 9 à 18 ans pratiquant le baseball, le basketball, le football, le soccer et l'athlétisme en Ontario.

Résultats

Presque tous les entraîneurs interrogés ont répondu correctement aux questions sur les effets de la consommation de TC sur la santé et environ 80 % d'entre eux ont répondu correctement à la question portant sur les dispositions législatives relatives au TC et aux jeunes.

Conclusion

La plupart des entraîneurs souhaiteraient recevoir de l'information sur le TC, en particulier sur les effets de la consommation de TC sur la santé et sur les façons de prévenir la consommation de TC chez les athlètes. L'information fournie aux entraîneurs devrait revêtir plusieurs formes et comprendre des documents électroniques et imprimés.

La population étudiée comprenait 592 femmes ayant fréquenté une clinique de dépistage utilisant le test de Papanicolaou (Pap). Après avoir signé un formulaire de consentement, les participantes répondaient à un questionnaire auto-administré sur les facteurs de risque et ont subi un test de Pap classique. Les cellules résiduelles des tests de Pap ont été recueillies et envoyées pour un typage du VPH.

Résultats

L'âge moyen de la population était de 43 ans. En tout, 115 participantes (19,4 %) étaient infectées par le VPH, 89 d'entre elles ayant obtenu un résultat normal au test de Pap. Parmi celles qui étaient positives pour le VPH, 61 (10,3 %) étaient infectées par un VPH à risque élevé (Groupe 1). Le VPH-16 était le type le plus répandu (15/115 : 13,0 % des infections). Les facteurs de risque d'infection par le VPH les plus fréquents étaient le jeune âge, l'origine autochtone, un nombre plus élevé de partenaires sexuels au cours de la vie et un nombre plus élevé de partenaires sexuels au cours de l'année précédente.

Conclusion

La prévalence des types de VPH au Manitoba correspond aux distributions signalées dans d'autres provinces ou territoires. Ces données fournissent des renseignements de base sur la prévalence du VPH de chaque type dans une population non vaccinée et peuvent aider à évaluer l'efficacité du programme de vaccination contre le VPH. En outre, ces données permettent d'effectuer une validation de principe du couplage d'un registre de tests de Pap basé sur une population avec les résultats de tests de laboratoire et une enquête sur les comportements à risque en vue d'évaluer les effets précoces et tardifs de l'infection par le VPH. Cette méthodologie pourrait être appliquée à d'autres provinces ou territoires au Canada disposant de ressources similaires.

Validation des codes de diagnostic de la CIM-9 pour la dysplasie bronchopulmonaire dans les bases de données de la Régie de l'assurance-maladie du Québec
Authors: Landry JS , Croitoru D , Menzies D
Published: October 2020

Introduction

La dysplasie bronchopulmonaire (DBP) est une maladie respiratoire chronique causée par une lésion pulmonaire néonatale. Cette étude a pour objet de valider l'utilisation des codes de diagnostic de la CIM-9 correspondant à la DBP dans les bases de données administratives pour déterminer s'ils peuvent être employés dans les analyses sur l'utilisation du système de soins de santé.

Méthodologie

Le processus de validation a fait appel à une cohorte rétrospective composée de nouveau-nés prématurés, ayant présenté ou non des complications respiratoires, qui avaient été admis à l'Hôpital de Montréal pour enfants, à Montréal (Québec), entre 1983 et 1992. Les sujets atteints de DBP ont été identifiés au moyen des codes de diagnostic de la CIM-9 dans les bases de données administratives provinciales (services médicaux et MED-ECHO), puis comparés à des sujets atteints d'une DBP confirmée dans la cohorte de validation. Nous avons examiné la concordance des données et avons estimé la sensibilité et la spécificité associées à l'utilisation de ces codes de diagnostic pour la DBP.

Résultats

Les cas dits « vrais positifs » de DBP et les cas dits « faux négatifs » de DBP ne présentaient pas de différences significatives selon l'âge gestationnel, le poids à la naissance et le score d'Apgar. L'âge gestationnel associé aux cas dits « faux positifs » de DBP était considérablement inférieur à celui des vrais négatifs. L'utilisation de codes de diagnostic de la CIM-9 pour la DBP a été associée à une spécificité se situant entre 97,6 % et 98,0 %. La sensibilité, plus faible, se situait à 45,0 % et à 52,4 % pour les bases de données sur les services médicaux et MED-ECHO, respectivement. Il est arrivé plus fréquemment que les cas légers de DBP ne soient pas décelés que les cas plus graves.

Conclusion

Le degré de spécificité des codes de diagnostic de la CIM-9 pour la DBP dans les bases de données de la Régie de l'assurance-maladie du Québec est suffisamment élevé pour permettre l'utilisation de ces codes de façon systématique. La sensibilité plus faible en ce qui concerne les cas légers se soldera probablement par une sous-estimation des répercussions de la DBP sur l'utilisation à long terme du système de soins de santé par les nouveau-nés prématurés.
L'influence des matchs de hockey professionnel vus à la télévision sur les blessures des jeunes hockeyeurs
Authors: Keays G , Pless B
Published: October 2020

Introduction

La plupart des matchs de la Ligue nationale de hockey (LNH) télédiffusés comportent des mises en échec violentes, des coups illégaux et des altercations. Nous avons émis l'hypothèse que les joueurs des ligues de hockey mineur imitaient de tels comportements et que le fait de ne pas regarder ces matchs se traduirait par une réduction du taux de blessures chez les joueurs de hockey plus jeunes.

Méthodologie

En utilisant un modèle quasi expérimental, nous avons comparé sept ans de matchs de la LNH télédiffusés (2002–2009) avec l'année du lock-out de la LNH (2004–2005). Nous avons utilisé les données du Système canadien hospitalier d'information et de recherche en prévention des traumatismes (SCHIRPT) pour caractériser les blessures et déterminer si elles étaient attribuables à un contact intentionnel ou à des actes illégaux, ce qui inclut les altercations.

Résultats

Nous n'avons observé aucune différence significative entre les proportions de blessures tous types confondus et celles liées à un contact intentionnel, un acte violent ou un acte illégal chez les joueurs de sexe masculin des ligues de hockey mineur entre l'année où les joueurs professionnels ont été en lock-out et les années précédentes et suivantes.

Conclusion

Nous concluons que le fait de ne pas voir de matchs télédiffusés de la LNH comportant des scènes violentes pourrait ne pas se traduire par une réduction des blessures, même si un effet possible pourrait avoir été masqué puisque nous avons observé une augmentation marquée, durant le lock-out, du nombre de spectateurs aux matchs des ligues mineures professionnelles où la violence est tout aussi présente.

Introduction

La surveillance des tendances concernant le cancer peut aider à évaluer les progrès réalisés dans la lutte contre le cancer ainsi qu'à renforcer les activités de prévention. La présente étude, fondée sur les données des bases de données nationales, consiste en un examen des tendances à long terme relatives à certains cancers au Canada.

Méthodologie

Nous avons examiné les changements annuels dans les tendances relatives aux taux d'incidence et de mortalité normalisés selon l'âge observés entre 1970 et 2007 selon le sexe pour tous les cancers combinés, pour les quatre cancers les plus courants (cancer de la prostate, cancer du sein, cancer du poumon, cancer colorectal) et pour les cancers dont les tendances ont été marquées par les changements les plus importants au cours des dernières années. Le rapport de survie relative à cinq ans pour les années 1992 à 2007 a également été calculé.

Résultats

Pendant la période visée par l'étude, les taux d'incidence de l'ensemble des cas de cancer primitif combinés ont augmenté de 0,9 % par année chez les hommes et de 0,8 % par année chez les femmes. Les taux concernant le mélanome, le cancer de la thyroïde, le cancer du foie, le cancer de la prostate, le cancer du rein, le cancer colorectal, le cancer du poumon, le cancer du sein et le cancer de la vessie ont augmenté à des rythmes variables, et les taux concernant le cancer du larynx, le cancer de la bouche, le cancer de l'estomac et le cancer du col de l'utérus ont diminué. Pour l'ensemble des cancers combinés et pour la plupart des cancers examinés, à l'exception du mélanome et du cancer du poumon chez les femmes, les taux de mortalité ont diminué significativement. Les taux de survie qui ont le plus augmenté sont ceux du cancer de la prostate, du cancer du foie, du cancer colorectal et du cancer du rein. Bien que les tendances globales concernant les taux de mortalité et la survie indiquent que des progrès notables ont été réalisés dans la lutte contre le cancer, la tendance à la hausse des taux d'incidence de certains cancers soulignent la nécessité de poursuivre les efforts dans le domaine de la prévention.

Published: October 2020

Introduction

Our study examines the association between the disease characteristics of inflammatory arthritis and patients' self-perception of mental health, parenting disability, parenting stress and child behaviour in early inflammatory arthritis (EIA).

Methods

Patients in the early phase (more than 6 weeks, less than 18 months) of inflammatory arthritis were recruited from a larger EIA registry that recorded sociodemographic data and measures of pain, physical functioning and disease activity. Patient-perceived parenting disability, parenting stress, depression and children's behaviour problems were assessed using the Parenting Disability Index, Parenting Stress Index, Center for Epidemiologic Studies - Depression Mood Scale and Child Behavior Checklist, respectively.

Results

Pain, physical dysfunction, number of tender joints and physician global assessment of disease activity were associated with parenting disability. Self-report measures of parenting disability were associated with those of depression and parenting stress. Parenting stress was associated with children internalizing and externalizing behaviour problems while parenting disability was associated with children externalizing behaviour problems.

Conclusion

This study suggests a possible reciprocal relationship among physical aspects of disease activity, parenting disability and parent and child distress in EIA.
