Risco recreacional associado à presença de cianobactérias no estuário do Complexo Lagunar da Baixada de Jacarepaguá, Rio de Janeiro, RJ, Brasil
Authors: Ferrao-Filho Aloysio , Moscatelli Mario 
Published: October 2020

As lagoas do complexo lagunar da Baixada de Jacarepaguá situam-se na zona Oeste do Rio de Janeiro, compreendendo as regiões de Jacarepaguá, Barra da Tijuca e Recreio dos Bandeirantes. A intensa ocupação urbana da região a partir da década de 70 transformou esse sistema num receptáculo de todo tipo de dejetos, sejam eles provenientes de esgotamento sanitário das residências e estabelecimentos comerciais, sejam de efluentes industriais. Isto levou a um processo de eutrofização acelerado, cuja consequência foi a dominância do fitoplâncton por cianobactérias toxicas. Este trabalho avaliou a presença de gêneros de cianobactérias potencialmente tóxicas no fitoplâncton em 3 pontos de amostragem na Lagoa da Tijuca e em 1 ponto na praia da Barra da Tijuca (Praia do Pepê), junto ao quebra-mar. O objetivo deste trabalho foi estimar os riscos potenciais que a população humana que frequenta este estuário está exposta e sugerir medidas preventivas.

Authors: Acosta Ramírez José Hernando 
Published: October 2020

Antecedentes: Entre los factores de riesgo asociados al BPN, se reportan las condiciones sociales adversas como el desempleo, la falta de seguridad alimentaria, la extrema pobreza y las barreras de acceso a los servicios de salud y las causas más frecuentes del bajo peso al nacer son los nacimientos pre-término y la restricción en el crecimiento fetal.
Objetivo: identificar la frecuencia y determinantes del bajo peso al nacer en un hospital de alta complejidad en Cali- Colombia.
Métodos: Estudio observacional analítico de casos y controles, retrospectivo. Se analizó la información de 906 nacimientos de embarazos únicos y a término, sucedidos entre octubre y diciembre de 2017; se identificaron 53 casos de bajo peso al nacer y se compararon con 853 nacimientos con peso normal.
Resultados: En los determinantes de BPN las variables de exposición que mostraron asociación fueron el tiempo de gestación OR de 10.2 (IC: 95% 4.7-21.9; p 0.000); ser primigestantes OR de 1.9 (IC 95%: 1.1-3.5; p 0.022).
Conclusión: el BPN puede ser explicado por variables biológicas con trasfondo sociodemográfico, concretamente la primigestación como riesgo de BPN en nuestra población.

Authors: S. Abulibdeh Enas , J I Badrasawi Kamal , Abu Kassim Noor Lide 
Published: October 2020

Purpose of the study: This paper examines the adequacy of an exit exam using the Rasch Model. It also addresses the students' achievement on the exam items according to Learning Outcomes (LOs) i.e. what LOs have been achieved and have not been achieved.
Main Findings: The Rasch analyses showed‎ that there were issues related to the adequacy of the exit exam in terms of the items' validity and items' distribution along the interval scale. The items' qualitative investigation revealed that the stems and options of some items have problems. Overall, the exam was easy for the students, and students scored different achievement according to Learning Outcomes (LOs). These findings highlight the importance of using measurement ‎models to validate exams as well as to provide a more accurate interpretation of ‎students' achievement; Rasch Model is an example.
Methodology: The descriptive quantitative research design was utilized to achieve the research objectives. An exam comprises 100 Multiple choice items/questions administered to 322 students taking Professional Diploma in Teaching at a College of Education. The items cover eight 8 Learning Outcomes that students were expected to achieve when completed all the Professional Diploma courses. The collected data were analyzed using the Rasch Model for dichotomous data, and Winsteps software 4.1.0 (2018).
Applications of this study: The study provides insightful information to higher institutions in general and to colleges of education to revamp the implementation of diploma teaching programs, mainly the assessment methods.
Novelty/Originality of this study: This paper extends the evidence of providing academic staff at higher institutions with necessary information and training on measurement to come out with more informed decisions.
The effect of primary years program (PYP) on children’s science process skills (SPS) in early childhood education
Authors: Tuğluk Mehmet Nur 
Published: October 2020

The aim of the current study was to investigate the effect of the Primary Years Program (PYP) on the science process skills (SPSs) of children in early childhood education. The study design was quasi-experimental and focused on children attending private schools in Istanbul. In this study, the Science Process Scale developed by Ozkan (2015) was used. Herein, approval for this study was granted by the Ministry of National Education, and consent was given by parents, to determine differences between their preschoolers who were attending an International Baccalaureate (IB) and Ministry of National Education school. Before implementing the PYP, a pretest was applied to the children in the experimental and control groups. After that, the children in the experimental group attended the PYP for 12 weeks. Conversely, the children in the control group attended the program of the Ministry of National Education. Following this 12-week period, the children were given a posttest. When the pretest results were compared after completing the IB program, there were no significant differences between the experimental and control groups. After the 12 weeks, a significant difference was found between the two groups with regards to their SPSs. When analyzed according to the factors, there seemed to be no differences between the two groups. However, at the end of the research, an interesting difference was found between the post and follow-up test results in the experimental group.

Authors: Dağyar Miray , Gamze Kasalak , Nermin Uğurlu 
Published: October 2020

This study aimed to determine to what extent undergraduate students’ level of academic career awareness and demographic variables predicted their level of academic career interest. The sample consisted of 3,696 students studying at 16 faculties, who were 3rd- and 4th-year undergraduate students from Akdeniz University in the fall semester of 2019–2020, and where the necessary permissions could be obtained from the faculty deanships for the application of the scales. The Academic Career Awareness Scale and Academic Career Interest Scale were used as data collection tools. The results obtained from the study were as follows: the level of undergraduate students’ academic career awareness was low and their level of academic career interest was above average. It was determined that the level of academic career interest of the undergraduate students changed according to their gender, grade level and their level of academic career awareness. When the demographic variables were measured, the level of academic career awareness explained the level of academic career interest. According to this result, it could be said that undergraduate students should have knowledge about academic career in order to be interested in an academic career.

This research has been conducted to examine the relationship between primary school 8th grade students’ levels of assertiveness and a) family function b) socio-demographic variables. In the research with the family assessment scale, rathus assertiveness and socio-demographic properties inventory has been used. The personal information form has been used for socio-demographic variables according to family assessment functions and social demographic properties, the students’ levels of assertiveness have been studied whether significantly differentiate (p<.05/p<.01) or not. Socio-demographic properties are gender, number of siblings, birth order, self-confidence and lack of self-confıdence, parents’ education level, and family income level. In the sample group there are 195 girl students and 236 boy students classes of the society totally 431 students form the sample group. As a result, the level of assertiveness doesn’t change according to the gender. Terms of roles, affective involvement and behaviour control, male students have higher average scores than female students. Generally the students who have got two siblings, have lower scores than the other number of siblings group (1,3,4,6); in terms of the relationship between the family function and assertiveness, the overall high scores have been found to cause a decrease in the communication, roles and general functions (sub-family functıons) of the 8th grade students’ levels of assertiveness.

Published: October 2020

This study investigates the students’ perceptions regarding their voices towards improvement in learning at public and private sector universities in Pakistan. These voices are collected by the Quality Enhancement Cells of the varsities through either technological tools or other ways. To understand how this data is utilized, a self-constructed and validated tool was utilized to get information about four categories; understanding of the term student voices, inquiry of learning process; university facilitation for best learning and implementation of student voices. Using purposive sampling technique, a survey of 112 under graduate students from four fields of studies (social sciences, natural sciences, business administrations and languages) from a Public and Private Sector University each from District Lahore was conducted. Data was analyzed by using SPSS version 22, and t-test and chi-square was performed to measure the difference in institutional facilitation of public and private sector universities. One-way ANOVA was applied to check the effects of student’s status in the class on the inquiry of learning process. The study indicated statistically significant effect of public and private sector on students’ perceptions regarding institutional facilitations for learning improvement. The study also reported the significant effects of student’s status on the inquiry of learning process. It is suggested that further studies need to explore how and where the students’ voices are being used for planning, assessment and course development.

Published: October 2020

This study investigated factors that are associated with the creative motor skills of young children. We recruited through random sampling 233 typically developing children attending preschool or kindergarten in Afyonkarahisar, Turkey. We administered a “General Information Form” to gather the children’s demographic characteristics and the “Thinking Creatively in Action and Movement Test” to evaluate the children’s creative motor skills level. We analyzed the children and familys’ demographic characteristics with frequency and percentage values, and we analyzed the TCAM with multiple linear regression analysis to determine whether independent variables predicted creativity on the TCAM. Our results showed that, among the sub-dimensions of the TCAM, the mother’s age and profession best predicted the sub-dimension of fluency and the mother’s profession best predicted the sub-dimension of novelty. Regarding, the sub-dimension of children's creative motor-imagination, neither the children’s gender or age, the parents’ age, education or occupation were significant predictors.

Effects of alcohol consumption in general, and wine in particular, on the risk of cancer development: a review
Authors: Teissedre Pierre-Louis , Rasines-Perea Zurine , Ruf Jean-Claude , Stockley Creina , Antoce Arina Oana , Romano Raquel , Fradera Ursula , Kosti Rena I. 
Published: October 2020

Since 1988, alcohol has been classified as a Group 1 carcinogen, the highest level of risk, by the International Agency for Research on Cancer (IARC). In fact, alcohol consumption is the third leading risk factor for disease and mortality in Europe. It accounts for 4.65 % of the global burden of both injury and disease, making it one of the most preventable causes of injury and death. Tissues in closest contact with alcohol when it is ingested, such as those of the oral cavity, pharynx, esophagus and larynx, have at greater risk of becoming cancerous than other body tissues. The consumption of alcohol is also associated with an increased risk of stomach, colon, rectum, liver, female breast and ovarian cancers. Conversely, recent studies suggest that red wine components inhibit colony formation of human breast cancer and esophageal carcinoma cells, suggesting that wine-derived phenolic compounds may be inhibitory, in contrast to the alcohol component of wine. Because of a lack of systematic studies dealing with the different types of cancer and alcoholic beverages and wine in particular, in this narrative review we summarize the general risk of cancer linked to the consumption of alcoholic beverages, including wine, according to type of cancer, with 140 extracted relevant references from 1966 to 2020. Mostly epidemiological studies concerning large cohorts have been selected. For the cancers of the upper aerodigestive tract, liver, colorectum, breast cancer, pancreatic, prostate, an excessive consumption and/or misuse of alcoholic beverages is correlated with increased risk. Conversely a probable decreased risk has been found for renal/kidney cancers, as well as for Non-Hodgkin lymphomas, such as thyroid lymphomas, associated with the moderate consumption of alcoholic beverages. There is no evidence of ovarian, gastric, head and neck, and lung cancer being linked to the moderate consumption of alcoholic beverages. Cancer is a multifactorial disease, and many factors contribute to effects on health status, usually being both genetic and environmental. Habits (smoking, dietary/lifestyle pattern/ habits, physical activity), should also be taken into account when defining appropriate consumption frequencies for different types of alcoholic drink (wine, beer, spirits). Further research is needed related to wine consumption in the context of a healthy dietary and lifestyle pattern given health-promoting constituents of wine and its effects on cancer incidence.

Published: October 2020

Background:
Computed tomography (CT), magnetic resonance imaging, and bone scintigraphy are second-line imaging techniques that are frequently used for the evaluation of patients with a clinically suspected scaphoid fracture. However, as a result of varying diagnostic performance results, no true reference standard exists for scaphoid fracture diagnosis. We hypothesized that the use of high-resolution peripheral quantitative CT (HR-pQCT) in patients with a clinically suspected scaphoid fracture could improve scaphoid fracture detection compared with conventional CT in the clinical setting.

Methods:
The present study included 91 consecutive patients (≥18 years of age) who presented to the emergency department with a clinically suspected scaphoid fracture between December 2017 and October 2018. All patients were clinically reassessed within 14 days after first presentation, followed by CT and HR-pQCT. If a scaphoid fracture was present, the fracture type was determined according to the Herbert classification system and correlation between CT and HR-pQCT was estimated with use of the Kendall W statistic or coefficient of concordance (W) (the closer to 1, the higher the correlation).

Results:
The cohort included 45 men and 46 women with a median age of 52 years (interquartile range, 29 to 67 years). HR-pQCT revealed a scaphoid fracture in 24 patients (26%), whereas CT revealed a scaphoid fracture in 15 patients (16%). Patients with a scaphoid fracture were younger and more often male. The correlation between CT and HR-pQCT was high for scaphoid fracture type according to the Herbert classification system (W = 0.793; 95% confidence interval [CI], 0.57 to 0.91; p < 0.001) and very high for scaphoid fracture location (W = 0.955; 95%, CI 0.90 to 0.98; p < 0.001).

Conclusions:
In the present study, the number of patients diagnosed with a scaphoid fracture was 60% higher when using HR-pQCT as compared with CT. These findings imply that a substantial proportion of fractures—in this study, more than one-third—will be missed by the current application of CT scanning in patients with a clinically suspected scaphoid fracture.

Influence of Femoral Component Design on Proximal Femoral Bone Mass After Total Hip Replacement
Authors: Slullitel Pablo A. , Mahatma Mohit M. , Farzi Mohsen , Grammatopoulos George , Wilkinson J. Mark , Beaulé Paul E. 
Published: October 2020

Background:
In this randomized controlled trial (RCT), we compared bone remodeling and bone turnover between 2 total hip arthroplasty implants—the short, proximally porous-coated Tri-Lock Bone-Preservation Stem and a conventional, fully-coated Corail prosthesis—over a 2-year postoperative period.

Methods:
Forty-six participants received the Tri-Lock prosthesis and 40 received the Corail prosthesis. At baseline, the 2 groups had similar demographics, proximal femoral bone mineral density (BMD), bone turnover markers, radiographic canal flare index, and patient-reported outcome measure (PROM) scores. Outcomes were measured at weeks 26, 52, and 104.

Results:
Loss of periprosthetic bone, measured by high-sensitivity dual x-ray absorptiometry region-free analysis (DXA-RFA), was identified at the calcar and proximal-lateral aspect of the femur in both prosthesis groups (p < 0.05). However, the conventional prosthesis was associated with a smaller reduction in BMD compared with the bone-preservation prosthesis (p < 0.001). This effect was most prominent in the region of the femoral calcar and greater trochanter. A small gain in BMD was also identified in some areas, and this gain was greater with the conventional than the bone-preservation prosthesis (p < 0.001). The 2 groups had similar changes in bone turnover markers and improvement in PROM scores over the study period (p > 0.05). The adverse-event rate was also similar between the groups (p > 0.05).

Conclusions:
This RCT shows that prostheses intended to preserve proximal femoral bone do not necessarily perform better in this regard than conventional cementless designs. DXA-RFA is a sensitive tool for detecting spatially complex patterns of periprosthetic bone remodeling.
