Profile Pictures

In this study, we examined the impact of demographics and relationship status on posting a revealing picture of oneself as a profile picture on Facebook. We randomly sampled and coded 1,000 profiles of Israeli Facebook users ranging in age between 18 and 61 years. Over 40% of the profiles showed at least 1 picture of the user dressed in a skimpy outfit. Results of a multiple logistic regression model indicated that younger age, a lower level of education, and not being engaged in a committed romantic relationship were significant predictors of the posting of these pictures. Further, gender alone was not a significant predictor, but the interaction of gender and level of education was. Specifically, women with a high-schoollevel education posted revealing pictures of themselves more often than did men with a similar level of education. We analyzed our results in light of Goffman's theory of self-presentation.

The Impact

The study sought to assess the dynamics of grasscutter (Thryonomys swinderianus) Produc­tion Technologies being used in the Agona West Municipality in the Central Region of Ghana. Farmers were selected from 20 communities with the help of staff from the Department of Ag­riculture and were interviewed using structured questionnaires. The results revealed that though the grasscutter farmers were varied in their views, the dissemination of grasscutter technologies through video in the study area was deemed to be effective. The results of the Logistic regression model (R-Square values of 0.119 and 0.158) showed that the impact of the dissemination pro­gramme on the livelihoods of farmers who had adopted the grasscutter production technologies was best predicted by age, household size and level of education of farmers. The overall mean, 3.99 showed that the livelihoods of the farmers had highly been improved. The paper makes a strong case for a more participatory approach anchored on inclusive problem identification and formulation of research solution that will further ensure that problems that are targeted by re­search emanate from farmers. This is expected to ensure a more effective extension of research technologies to farmers and other actors along the grasscutter value chain in the area. Keywords: Grasscutter; Production Technologies; Agona West Municipality; Central Region; Ghana

Furosemide Administration

OBJECT A major challenge in sagittal craniosynostosis surgery is the high transfusion rate (50%–100%) related to blood loss in small pediatric patients. Several approaches have been proposed to prevent packed red blood cell (PRBC) transfusion, including endoscopic surgery, erythropoietin ortranexamic acid administration, and preoperative hemodilution. The authors hypothesized that a significant proportion of postoperative anemia observed in pediatric patients is actually dilutional. Consequently, since 2005, at CHU Sainte-Justine, furosemide has been administered to correct the volemic status and prevent PRBC transfusion. The purpose of this study was to evaluate the impact of postoperative furosemide administration on PRBC transfusion rates. METHODS This was a retrospective study of 96 consecutive patients with sagittal synostosis who underwent surgery at CHU Sainte-Justine between January 2000 and May 2012. The mean age at surgery was 4.9 ± 1.5 months (range 2.8–8.7 months). Patients who had surgery before 2005 constituted the control group. Those who had surgery in 2005 or 2006 were considered part of an implementation phase because furosemide administration was not routine. Patients who had surgery after 2006 were part of the experimental (or furosemide) group. Transfusion rates among the 3 groups were compared. The impact of furosemide administration on transfusion requirement was also measured while accounting for other variables of interest in a multiple logistic regression model. RESULTS The total transfusion rate was significantly reduced in the furosemide group compared with the control group (31.3% vs 62.5%, respectively; p = 0.009), mirroring the decrease in the postoperative transfusion rate between the groups (18.3% vs 50.0%, respectively; p = 0.003). The postoperative transfusion threshold remained similar throughout the study (mean hemoglobin 56.0 g/dl vs 60.9 g/dl for control and furosemide groups, respectively; p = 0.085). The proportion of nontransfused patients with recorded hemoglobin below 70 g/dl did not differ between the control and furosemide groups (41.7% vs 28.6%, respectively; p = 0.489). Surgical procedure, preoperative hemoglobin level, estimated blood loss, and furosemide administration significantly affected the risk of receiving a postoperative PRBC transfusion. When these variables were analyzed in a multiple logistic regression model, furosemide administration remained strongly associated with a reduced risk of being exposed to a blood transfusion (OR 0.196, p = 0.005). There were no complications related to furosemide administration. CONCLUSIONS A significant part of the postoperative anemia observed in patients who underwent sagittal craniosynostosis surgery was due to hypervolemic hemodilution. Correction of the volemic status with furosemide administration significantly reduces postoperative PRBC transfusion requirements in these patients.

Abstract Background Studies on the impact of patients with multimorbidity in the absence of work indicate that the number and type of chronic diseases may increase absenteeism and that the risk of absence from work is higher in people with two or more chronic diseases. This study analyzed the association between multimorbidity and greater frequency and duration of work absence in the portuguese population between the ages of 25 and 65 during 2015. Methods This is an epidemiological, observational, cross-sectional study with an analytical component that has its source of information from the 1st National Health Examination Survey. The study analyzed univariate, bivariate and multivariate variables under study. A multivariate logistic regression model was constructed. Results The prevalence of absenteeism was 55,1%. Education showed an association with absence of work (p = 0,0157), as well as professional activity (p = 0,0086). It wasn't possible to verify association between the presence of chronic diseases (p = 0,9358) or the presence of multimorbidity (p = 0,4309) with absence of work. The prevalence of multimorbidity was 31,8%. There was association between age (p < 0,0001), education (p < 0,001) and yield (p = 0,0009) and multimorbidity. There is no increase in the number of days of absence from work due to the increase in the number of chronic diseases. In the optimized logistic regression model the only variables that demonstrated association with the variable labor absence were age (p = 0,0391) and education (0,0089). Conclusions The scientific evidence generated will contribute to the current discussion on the need for the health and social security system to develop policies to patients with multimorbidity. Key messages The prevalence of absenteeism and multimorbidity in Portugal was respectively 55,1% and 31,8%. In the optimized model age and education demonstrated association with the variable labor absence.

The Impact

The aim of this study is the analysis of the effect that the entrepreneurship activities have in the development of an entrepreneurial profile of the students of a secondary level and their future entrepreneurial intentions. To empirically test the formulated hypothesis, a questionnaire was developed. By the application of methods of factorial analysis and a logistic regression model, it was concluded that variables like the incentive given by school agents, the participation of students in extracurricular activities and the desire to continue studying, influenced the entrepreneurial intentions of the students. Concerning the entrepreneurial profile, it was concluded that the students who have higher capacity of creation and concretization of entrepreneurial projects and a winning will, have a higher propensity to create their own business. This research analysed the impact of entrepreneurship activities on the development of the secondary school students' entrepreneurial profile, and understand whether these same activities influence their future intentions.

The objective of the study was to assess the use of helmets in a community where helmet use is mandatory but low as there is no police enforcement. A sample comprising 451 motorcyclists in the city of Mar del Plata, Argentina, was studied in 2006. The following variables were studied: gender, type of motorcycle, weather conditions, time of the day, city area and type of road where motorcyclists traveled. Data were analyzed through a multiple logistic regression model. An overall 40% prevalence (95% CI: 35.5;44.5) of helmet use was found. Higher rates of helmet use were seen among women, and under unfavorable weather conditions, lower rates were found in the city outskirts, and variable use was seen according to the type of motorcycle. There is a need to improve law enforcement and to promote education of motorcyclists.

Simple Logistic

This study shows how simple and multiple logistic regression can be used in observational methodology and more specifically, in the fields of physical activity and sport. We demonstrate this in a study designed to determine whether three-a-side futsal or five-a-side futsal is more suited to the needs and potential of children aged 6-to-8 years. We constructed a multiple logistic regression model to analyze use of space (depth of play) and three simple logistic regression models to determine which game format is more likely to potentiate effective technical and tactical performance.
