Published: May 2020

<p align="center">This action research project aimed to improve the participation of learners in the class of General English. Collaborative activities were designed by grouping learners to work with the assigned tasks. The data were collected through observation. The findings showed that the participation of learners increased greatly characterized by the involvement of all learners in more active participation through group discussions and presentations of their works. Furthermore, the findings revealed that the learners look more confident to speak, more motivated to complete the assigned tasks, more enjoyable in learning, more focused on the lesson, and more engaged to think critically and creatively. In the attempt to disseminate our teaching experience, this article mainly focuses on the practical implementation of our collaborative action that is aimed to encourage other teachers and practitioners to implement the same research to improve their practices. </p><p align="center"> </p>
De la historia local a la historia pública: algún defecto y ciertas virtudes = From local to public history. Some weakness and certain achievements
Authors: Pons Anaclet 
Published: May 2020

Resumen: Como solemos decir, la profesionalización de nuestra disciplina produjo una cesura, separando la historia académica de aquella otra que quedaba en manos de eruditos, archiveros. Y mientras unos se dedicaban a la historia nacional, otros quedaban relegados a lo local y a la mera nostalgia. Esa idea se mantuvo al menos hasta los años setenta. El cambio, como es sabido, estuvo relacionado con los movimientos sociales de la década anterior, que a grandes rasgos supusieron el retorno del sujeto, con una dimensión múltiple, y el énfasis en la acción humana. Este ensayo historiográfico explora esos cambios, a partir sobre todo de dos diferentes propuestas de rescate de lo local -la microhistoria y la historia popular-, y muestra cómo actualmente esa defensa de lo local se combina en buena medida con la historia pública.Palabras clave: Historia local, historia pública, microhistoria, historia popular, historiografía.Abstract: As we usually say, the professionalization of our discipline produced a caesura, separating the academic history from such other in hands of erudites, archivists and amateurs. And while the first were dedicated to national history, the second were relegated instead to the local and the mere nostalgia. That idea was maintained at least until the 1970s. The change, as is known, was closely related to the social movements in the previous decade, which broadly assumed the return of the subject, with a multiple dimension, and the emphasis on human action. This historiographical essay explores these changes, starting from two different proposals for the rescue of the local - microhistory and popular history - and shows how the current defence of the local is largely combined with public history.Keywords: Local history, public history, microhistory, popular history, historiography.

Published: May 2020

Objectives: In Morocco, the exact and recent prevalence of Hepatitis C Virus (HCV) infection is not well-known, due to the lack of recent epidemiological studies of the general Moroccan population. The objective of this study was to determine the prevalence of HCV and to describe the epidemiological, clinical and virological characteristics of patients infected with HCV diagnosed at the Mohammed V Military Teaching Hospital in Rabat, Morocco.
Methods: This was a prospective study, spread over a period of 3 years (April 2015 - April 2018). All patients with a positive anti-HCV serology were included in the study except those on hemodialysis. In addition to HCV serology, all patients included benefited from HIV serology as well as the Hbs antigen by a Chemiluminescent type Microparticle Immuno-Assay technique (Architect®, Abbott). RNA viral load and HCV genotyping was carried out using a real-time polymerase chain reaction.
Results: We collected 14,944 samples, of which 269 had positive anti-HCV antibodies (1.8%). The average age of patients with positive HCV serology was 61 years, the sex ratio (Male/Female) was 1.4. Dental care was identified in 53% of the cases. Viral hepatitis C was identified in 82% of cases during a systematic check up. The main clinical signs reported in our series were asthenia (25% of cases) and subicterus (7% of cases).
Conclusion and Implications for Translation: In Morocco, the exact prevalence of HCV infection is not well known, due to the lack of recent epidemiological studies of the general Moroccan population. Our study showed a prevalence of about 1.8% which is in accordance with the World Health Organization (WHO) estimation of between 1% and 2.49%.Our Epidemiological study provides important on the extent of the problem in Morocco, it raises the interest of mass screening and describes the populations at risk that will need to be identified as a priority.

An Integrated Genetic-Algorithm/Artificial-Neural-Network Approach for Steady-State Modeling of Two-Phase Pressure Drop in Pipes
Authors: Chaari Majdi , Ben Hmida Jalel , Seibi Abdennour C. , Fekih Afef 
Published: May 2020

Summary
Modeling of multiphase flow represents the cornerstone of oil/gas-production systems. Accurate pressure-drop estimation is crucial in the design and operations of subsea architectures. However, the complexity of the underlying physics governing the transport of mass, momentum, and energy considerably limits the accuracy of the current state-of-the-art models. In this paper, we resort to artificial intelligence to develop a unifying artificial-neural-network (ANN) model encompassing all flow conditions. A genetic algorithm (GA) is used to find the optimal input combination from a broad pool of candidates leading to the best prediction accuracy. To train and validate the model, we used the Stanford multiphase-flow database (SMFD). Comprising 5,659 measurements (1,800 of which are actual field data), the SMFD is the largest of its kind encompassing several published data sets. Eighty percent of the data were used to train the model (4,527 measurements) and the remaining 20% (1,132 measurements) were used for validation. The proposed model was compared with two published models, the Beggs and Brill (1973) model, which is widely used in the oil and gas industry, and the Petalas and Aziz (2000) model (a preeminent mechanistic model). The proposed model was proved to significantly increase the prediction accuracy across all pipe-inclination ranges (up to 88%) and also all observed flow patterns (up to 71%). This is a major contribution with potential benefits to the oil and gas industry, where, because of the limited accuracy of the current models, much conservatism is used in the design of subsea architectures, leading to shortfalls of millions in profits.

Abstract
Background: In bacteria, pan-genomes are the result of an evolutionary "tug of war" between selection and horizontal gene transfer (HGT). High rates of HGT increase the genetic pool and the effective population size (Ne), resulting in open pan-genomes. In contrast, selective pressures can lead to local adaptation by purging the variation introduced by HGT and mutation, resulting in closed pan-genomes and clonal lineages. In this study, we explored both hypotheses, elucidating the pan-genome of Vibrionaceae isolates after a perturbation event in the endangered oasis of Cuatro Ciénegas Basin (CCB), Mexico, and looking for signals of adaptation to the environments in their genomes. Results: We obtained 42 genomes of Vibrionaceae distributed in six lineages, two of them did not showed any close reference strain in databases. Five of the lineages showed closed pan-genomes and were associated to either water or sediment environment; their high Ne estimates suggest that these lineages are not from a recent origin. The only clade with an open pan-genome was found in both environments and was formed by ten genetic groups with low Ne, suggesting a recent origin. The recombination and mutation estimators (r/m) ranged from 0.005 to 2.725, which are similar to oceanic Vibrionaceae estimations. However, we identified 367 gene families with signals of positive selection, most of them found in the core genome; suggesting that despite recombination, natural selection moves the Vibrionaceae CCB lineages to local adaptation, purging the genomes and keeping closed pan-genome patterns. Moreover, we identify 598 SNPs associated with an unstructured environment; some of the genes associated with these SNPs were related to sodium transport.Conclusions: Different lines of evidence suggest that the sampled Vibrionaceae, are part of the rare biosphere usually living under famine conditions. Two of these lineages were reported for the first time. Most Vibrionaceae lineages of CCB are adapted to their micro-habitats rather than to the sampled environments. This pattern of adaptation is concordant with the association of closed pan-genomes and local adaptation.

Abstract
Background : Evidence regarding the relationship between anemia and perioperative prognosis is controversial. The study was conducted to highlight the specific relationship between anemia and perioperative mortality in non-cardiac surgery patients over 18 years of age. Methods: This study was a retrospective analysis of the electronic medical records of 90,784 patients at the Singapore General Hospital from January 1, 2012 to October 31, 2016. Multivariate regression, propensity score analysis, doubly robust estimation, and an inverse probability-weighting model was used to ensure the robustness of our findings. Results : We identified 85,989 patients, of whom75, 163 had none or mild anemia(Hemoglobin>90g/L) and 10,826 had moderate or severe anemia(Hemoglobin≤90g/L). 8,857 patients in each study exposure group had similar propensity scores and were included in the analyses. In the doubly robust model, postoperative 30-day mortality rate was increased by 0.51% (n = 219) in moderate or severe anemia group (Odds Ratio, 1.510; 95% Confidence Interval(CI), 1.049 to 2.174) compared with none or mild anemia group (2.47% vs. 1.22%, P<0.001). Moderate or severe anemia was also associated with increased postoperative blood transfusion rates (OR, 5.608; 95% CI, 4.026 to 7.811, P < 0.001).There was no statistical difference in Intensive Care Unit(ICU) admission rate among different anemia groups within 30 days after surgery (P=0.104). Discussion: In patients undergoing non-cardiac surgery over 18 years old, moderate or severe preoperative anemia would increase the occurrence of postoperative blood transfusion and the risk of death, rather than ICU admission within 30 days after surgery.

Abstract
Background: Daily oral pre-exposure prophylaxis (PrEP) can reduce HIV infection in adolescent girls and young women if used consistently during periods of risk. The EMPOWER study evaluated peer-based clubs incorporating an empowerment curriculum offered to adolescent girls and young women (16-24 years) in South Africa and Tanzania for adherence support. Methods: Using serial in-depth interviews (n=33), we assessed the benefits and challenges of club attendance among 13 EMPOWER participants in the Johannesburg site who were randomised to clubs. We used a summary matrix of coded data to support a narrative, case-based analysis. Four case studies are presented. Results: Club participants reported benefits such as increased self-esteem and self-efficacy, reduced isolation, and greater insight into gender-based violence and strategies to address it. Day-to-day PrEP adherence was not the only topic discussed in clubs; participants also appreciated the safe space for sharing problems (such as relationship conflict and PrEP stigma) and found interactive exercises helpful in improving partner communication.Conclusions: Findings support the use of peer-based clubs using a structured empowerment approach, which may offer valuable PrEP initiation support to adolescent girls and young women in settings with high HIV and gender-based violence prevalence.Trial registration: South African Clinical Trial Register 4353, 15 April 2016

Published: May 2020

Abstract
Background Syringe service programs (SSPs) are an evidence-based harm reduction strategy that reduce dangerous sequelae of injection drug use among people who inject drugs (PWID) such as overdose. SSP services include safer injection education and community-based naloxone distribution programs. This study evaluates differences in overdose-associated hospital admissions following implementation of the first legal SSP in Florida, based in Miami-Dade County. Methods We performed a retrospective analysis of hospitalizations for injection drug-related sequelae at a county hospital before and after the implementation of the SSP. An algorithm utilizing ICD-10 codes for opioid use and sequelae was used to identify people who inject opioids (PWIO). Florida Department of Law Enforcement Medical Examiners Commission Report data was used to analyze concurrent overdose death trends in Florida counties. Results Over the 25-month study period, 302 PWIO admissions were identified; 146 in the pre-index vs. 156 in post-index. A total of 26 admissions with PWIO overdose were found; 20 pre-index and 6 post-index (p=0.0034). Conclusions Declining overdose-associated admissions among PWIO suggests early impacts following SSP implementation. These results indicate a potential early benefit of SSP that should be further explored for its effects on future hospital admission and mortality.

Published: May 2020

Abstract
Background: Adolescents are engaged in agricultural work, including pesticide application, around the world. Adolescent pesticide applicators are more likely to be exposed to pesticides than their adult counterparts because of their application practice and hygiene habits surrounding pesticide use. There is a need for low-cost interventions to reduce pesticide exposure. We evaluated a theoretically-based educational intervention to change perceptions about the risk of pesticide use and hygiene habits during and after pesticide application for adolescent and young adult pesticide applicators in Egypt.Methods: Young adult and adolescent male pesticide applicators were given a one-hour educational intervention to inform them about the risk of pesticide use and how to reduce pesticide exposure. The median age of participants was 18 years old. Changes in perceived susceptibility and effectiveness were measured with a survey pre and post-intervention (n=119) on the same day. The same survey (n=95) was given 8-months post-intervention to identify sustained effects. Observational checklists of pesticide application practice were also completed during application seasons before and after the intervention.Results: There was an increase in the proportion of individuals who viewed pesticides as being a long-term health risk (74.7% pre-intervention to 97.9% post-intervention, McNemar test p<0.001). This change remained significant when surveyed at the 8-month follow-up (90.5%, p<0.001). There was also a sustained improvement regarding participants’ views of proper hygiene practice surrounding pesticide application. Applicators were observed wearing goggles, shoes, and masks more frequently post-intervention.Conclusion: This theoretically-based intervention is an example of a low-cost solution that can improve adolescents’ and young adults’ practices regarding pesticide application and personal hygiene practices during and after pesticide application. The intervention can be applied in other countries with similar safety culture surrounding pesticide application.

Abstract
Background Our objective was to develop a disease progression model for cognitive decline in Alzheimer’s disease (AD) and to determine whether disease progression of AD is related to the year of publication, add-on trial design, and geographical regions. Methods Placebo-controlled randomized AD clinical trials were systemically searched in public databases. Longitudinal placebo response (mean change from baseline in the cognitive subscale of the Alzheimer’s Disease Assessment Scale [ADAS-cog]) and the corresponding demographic information were extracted to establish a disease progression model. Covariate screening and subgroup analyses were performed to identify potential factors affecting the disease progression rate. Results A total of 134 publications (140 trials) were included in this model-based meta-analysis. The typical disease progression rate was 5.82 points per year. The baseline ADAS-cog score was included in the final model using an inverse-U type function. Age was found to be negatively correlated with disease progression rate. After correcting the baseline ADAS-cog score and the age effect, no significant difference in disease progression rate was found between trials published before and after 2008, and between trials using add-on design and those that did not use add-on design. However, a significant difference was found among different trial regions. Trials in East Asian countries showed the slowest decline rate and the largest placebo effect. Conclusions Our model successfully quantified AD disease progression by integrating baseline ADAS-cog score and age as important predictors. These factors and geographic location should be considered when optimizing future trial designs and conducting indirect comparisons of clinical outcomes.
