Published: May 2021

La migración irregular ha sido un fenómeno sociohistórico persistente en los últimos cuarenta años en El Salvador, motivado fundamentalmente por las difíciles condiciones económicas y la falta de oportunidades laborales. En el país, se generan escenarios de exclusión social que impulsan la emigración de muchos ciudadanos que se marchan con la esperanza de obtener prosperidad económica y un entorno sociocultural estable en otros territorios. Siendo un fenómeno de gran trascendencia, la migración irregular debe ser abordada desde una perspectiva multicausal y científica, enfocando sus matices económicos, políticos y socioculturales, en los que se ve involucrada mayoritariamente la población joven. La aproximación a dicho fenómeno permite redefinir acciones de gobiernos e instituciones de la sociedad en favor de la integridad, la dignidad y el respeto a los derechos humanos de las personas migrantes y retornadas, lo que permite implementar estrategias interinstitucionales en materia socioeducativa y laboral que incidan en la prevención de la migración. Partiendo de estas consideraciones, se investigó la realidad de jóvenes estudiantes del municipio de San Miguel residentes en zonas urbanas y rurales, para conocer sus expectativas y opiniones respecto a la posibilidad de migrar debido a las condiciones socioeconómicas y al contexto de inseguridad en que viven; asimismo, se estudiaron las experiencias de jóvenes que vivieron de cerca el fenómeno de la migración irregular y volvieron al país en calidad de retornados. Por otra parte, se indagó en el trabajo de asistencia de diversas instituciones que se vinculan medularmente con migrantes y retornados, mediante iniciativas y proyectos para su reinserción socioeconómica.
Prototipo de muro ecológico no estructural elaborado con productos plásticos tereftalato de polietileno (PET)
Authors: Hernández Durán Hernán José 
Published: May 2021

La presente investigación contempla un análisis de dos problemáticas que posee El Salvador: el déficit de vivienda de la población de escasos recursos y la sobreproducción de botellas de plástico de tereftalato de polietileno. La investigación busca relación estas dos problemáticas con los Objetivos de Desarrollo Sostenible, los cuales son una iniciativa impulsada por Naciones Unidas para dar continuidad a la agenda de desarrollo tras los Objetivos de Desarrollo del Milenio, y los dos objetivos relacionados son colaborar con el país e la creación de ciudades y comunidades sostenibles construyendo un prototipo de muro ecológico. Esta investigación busca, además, contribuir a la construcción de futuras viviendas de tipo social, reutilizando las botellas de PET como principal materia prima el cual es un plástico elaborado con tereftalato de polietileno que es utilizado en envases de bebidas y textiles, capacitando a los pobladores de las diferentes zonas del país a través de instituciones gubernamentales y no gubernamentales, convirtiéndolos en comunidades constructoras capaces de planificar, gestionar y elaborar lo necesario para ser ejes de desarrollo local. Además, se busca la disminución de estos plásticos en los ecosistemas terrestres y marinos, pues muchas de las botellas de PET, al no recibir un tratamiento de reciclaje, son enterradas, quemadas y muchas veces llegan a quebradas, ríos y finalizan en el océano, afectando la vida de diferentes especies.
Fortalecimiento del vínculo universidad - empresa para generar oportunidades laborales en la zona oriental
Authors: Vaquerano Benavides José Rigoberto 
Published: May 2021

La vinculación entre universidades y empresas, tradicionalmente ha sido débil. Del mismo modo, ha sido escasa o nula la intermediación del Estado para coadyuvar a fortalecer dicho vínculo. Consecuentemente, cada sector ha venido realizando su labor como la considera conveniente. Las instituciones mencionadas, al ejercer su compromiso con la sociedad de forma individual y aislada, pierden grandes oportunidades de realizar un trabajo conjunto, enriquecedor y sinérgico que podría contribuir a ofrecer mejores resultados al país. Históricamente han persistido esfuerzos disociados entre el sector empresarial y las instituciones de educación superior, lo que ha generado insatisfacción en las expectativas de los empleadores, señalando vacíos en la formación académica y el desempeño real de los nuevos profesionales. Hasta ahora la comunicación e interacción mutua ha sido débil y atomizada, careciendo de visión respecto a los beneficios que se pueden obtener si se trabajara asociativamente, bajo el arbitraje estatal, como verdaderos aliados estratégicos. Por tanto, se estableció como propósito de esta investigación abordar los mecanismos que fortalezcan el vínculo universidad–empresa para generar oportunidades laborales en la Zona Oriental de El Salvador, perfilando las competencias del estudiante universitario, indagando en los requerimientos laborales establecidos por las empresas y contrastando la visión empresarial y educativa en el cumplimiento del compromiso con el desarrollo socioeconómico del país. La información fue proporcionada por estudiantes universitarios, empresas y funcionarios académicos de las universidades establecidas en la Zona Oriental del país. La investigación está sustentada teóricamente en los más recientes modelos de vinculación tripartita universidad, empresa, Estado.

Roles of Cobalt Doping on Structural and Optical of ZnO Thin Films by Ultrasonic Spray Pyrolysis
Authors: Roguai Sabrina , Djelloul Abdelkader 
Published: May 2021

Here we report a systematic study of structural, optical, and magnetic measurements of Zn1-xCoxO (x = 0–0.22 at.%) by Ultrasound pyrolysis spray technique. The hexagonal wurtzite structure of our films is confirmed by X-ray diffraction with an average crystallite size estimated in the range of 18–30 nm. For the optical proprieties, using the Levenberg–Marquardt least squares rule, the experimental transmission measurements were perfectly adapted to the transmission data calculated by a combination of the Wemple-DiDomenico model, the absorption coefficient of an electronic transition and the Tauc-Urbach model. The concentration of the NCo absorption centers and the oscillator intensity f of the d-d transition of Co2+ ions are determined by the Smakula method. The presence of high concentrations of localized states in the thin films is responsible for the reduction in the width of optical bandgap.
Preterm Labour

Published: May 2021

Preterm delivery is defined as delivery before 37 weeks completed gestation. It represents a major cause of neonatal morbidity and mortality and accounts for 5–10% of all deliveries. Cervical length assessment between 16–24 weeks and positive fetal fibronectin beyond 21 weeks gestation are proved to useful tools in prediction of preterm labour. Treating asymptomatic bacteruia and bacterial vaginosis in high-risk women reduces the incidence of preterm labour. Cervical cerclage is recommended to reduce the incidence of preterm birth in women with 2nd trimester losses and those with cervical length of 25 mm or less on transvaginal ultrasound between 16–24 weks gestation. Atosiban and nifidipine are currently the agents of choice in tocolysis. Antenal steriods in womens with threating preterm labour reduces the perinatal morbidties. Magnisum sulphate role is established for neuroprotection especially in extreme gestations between 24–30 weeks. Vaginal delivery is mode of choice for delivery with consideration to avoid fetal blood sampling, fetal scalp electrodes and ventouse prior to 34 weeks gestations. Caesarean section is considered for obstetric reasons that guide labour management at term.

The 3D-perovskite halides have gained a considerable reputation versus their counterpart semiconductor materials since they achieved a remarkable high-power conversion efficiency of 25.2% within a decade. Perovskite solar cells also have some problems as lattice degradation and sensitivity against moisture, oxygen, and strong irradiation. The perovskite instability is the drawback in front of this emerging technology towards mass production and commercialization. 2D-perovskites, with the general formula A2Bn − 1MnX3n + 1, have been recently introduced to overcome some of the drawbacks of the stability of 3D-perovskites; however, this is at the expense of sacrificing a part of the power conversion efficiency. Mixed 2D/3D perovskites could solve this dilemma towards the way to high stability-efficiency perovskites. The research is expected to obtain highly stable and efficient mixed 2D/3D perovskite solar cells in the few coming years. This chapter reviews 2D-perovskites’ achieved progress, highlighting their properties, current trends, challenges, and future prospects.

Authors: R.A. Mans Dennis , Friperson Priscilla , Djotaroeno Meryll , Pawirodihardjo Jennifer 
Published: May 2021

The Republic of Suriname (South America) is among the culturally, ethnically, and religiously most diverse countries in the world. Suriname’s population of about 600,000 consists of peoples from all continents including the Javanese who arrived in the country between 1890 and 1939 as indentured laborers to work on sugar cane plantations. After expiration of their five-year contract, some Javanese returned to Indonesia while others migrated to The Netherlands (the former colonial master of both Suriname and Indonesia), but many settled in Suriname. Today, the Javanese community of about 80,000 has been integrated well in Suriname but has preserved many of their traditions and rituals. This holds true for their language, religion, cultural expressions, and forms of entertainment. The Javanese have also maintained their traditional medical practices that are based on Jamu. Jamu has its origin in the Mataram Kingdom era in ancient Java, some 1300 years ago, and is mostly based on a variety of plant species. The many Jamu products are called jamus. The first part of this chapter presented a brief background of Suriname, addressed the history of the Surinamese Javanese as well as some of the religious and cultural expressions of this group, focused on Jamu, and comprehensively dealt with four medicinal plants that are commonly used by the Javanese. This second part of the chapter continues with an equally extensive narrative of six more such plants and concludes with a few remarks on the contribution of Javanese jamus to Suriname’s traditional medicinal pharmacopeia.
Medication Discrepancy Risk Factors for Pediatric Patients With Epilepsy at Hospital Admission

Published: May 2021

BACKGROUND
Children with epilepsy are at increased risk of medication errors due to disease complexity and administration of time-sensitive medication. Errors frequently occur during transitions of care between home and hospital, a time when accuracy of medication history lists is difficult to ascertain. Adverse events likely from medication discrepancies underscore the importance of improving medication reconciliation upon inpatient intake. This quality improvement project was designed to evaluate and optimize the current medication history process in epileptic patients upon hospital admission at a pediatric academic hospital.

METHODS
A retrospective chart review was conducted on 30 patients with epilepsy admitted in during April, July, and October 2018 to identify unintentional medication discrepancies among 6 sources: documented medication history, inpatient orders from the electronic medical record, outpatient clinic notes, inpatient history and admission document, phone message records, and external insurance claims.

RESULTS
A total of 63% percent of patients had at least 1 unintentional medication discrepancy. Most discrepancies occurred with daily maintenance anticonvulsants (63%). The most common types were omission of medication history (31%) and inpatient order omissions (27%). The number of medication histories completed with at least 1 discrepancy varied across pharmacists, nurses, and physicians, yet differences were not statistically significant.

CONCLUSIONS
Our study found a higher incidence of anticonvulsant discrepancies compared with previous studies. This quality improvement initiative identified the absence of a standardized process as the root cause for the high incidence of anticonvulsant discrepancies in pediatric patients with epilepsy at hospital admission.
Stability-indicating LC-MS Method for Determination of Stability of Extemporaneously Compounded Buprenorphine Oral Syringes for Neonatal Abstinence Syndrome

Published: May 2021

OBJECTIVE
In the hospital settings, buprenorphine is used for the treatment of patients with neonatal abstinence syndrome. It is extemporaneously compounded and stored in oral plastic syringes. However, limited information exists about the stability of buprenorphine and its compounded formulations when stored under specific conditions. Hence, we developed a stability-indicating high-performance liquid chromatography–mass spectrometry (LC-MS) method to analyze the stability of buprenorphine over time.

METHODS
A stability-indicating LC-MS method was developed to map the potential degradation peaks of buprenorphine when exposed to acidic, basic, and oxidative conditions. This method was used to study the stability of compounded buprenorphine oral syringes stored under refrigeration (2°C–8°C) and room temperature (25°C ± 2°C with 60% relative humidity). Syringes from each storage condition were assessed for stability using pH meter and stability-indicating LC-MS assay for 30 days.

RESULTS
Buprenorphine gets completely degraded in the presence of acid at the end of 1 hour of exposure. Various degradation peaks were identified using LC-MS assay for buprenorphine under acidic, basic, and peroxide conditions. Stability study of oral buprenorphine syringes showed no precipitation, cloudiness, or color change during this study at all storage conditions. The LC-MS assay revealed that buprenorphine oral syringes retained greater than 90% of the initial concentrations for 30 days.

CONCLUSIONS
Highly sensitive stability-indicating LC-MS method was developed for studying the stability of extemporaneously compounded buprenorphine oral syringes. This study demonstrates that buprenorphine extemporaneous formulation prepared according to the manufacturers' recommendations is stable under refrigerated or room temperature conditions for 30 days in oral plastic syringes.

Introdução:A glicosúria é a excreção de glicose na urina em concentrações detectáveis e normalmente, praticamente toda a glicose é filtrada livremente no glomérulo. Na hiperglicemia ou disfunção tubular, a glicose pode ser detectada na urina. Objetivo: Avaliar a concordância entre a glicemia sanguínea de jejum e a glicosúriaem pacientes atendidos em um laboratório do noroeste do Rio Grande do Sul.Resultados: A amostra deste estudo foi composta por 438 pacientes, com média de idade de 43 anos (±19), sendo 307 (70%) do sexo feminino. Dentre os casos, 295 (67%) não tiveram alteração, 12 (3%) apresentaram glicemia normal e glicosúria positiva e 46 (10%) apresentaram níveis de glicosúria e glicemia alterados. Considerando os pacientes com hiperglicemia, 78 (63%) não apresentaram glicosúria e obtiveram média de glicemia de 115mg/dL (±34) e 5 (4%) apresentaram uma cruz, obtendo glicemia média de 129mg/dL (±37). Dentre os 58 pacientes com alteração na glicosúria, 14 (24%) apresentaram glicemia sanguínea menor do que 160mg/dL, com média de glicemia de 120mg/dL (±15). Conclusão: Não há uma relação direta entre os níveis de glicemia sanguínea e glicosúria. A alteração na glicosúria foi mais presente em pacientes idosos e adultos e, em relação ao sexo, foi prevalente nas mulheres. O limiar renal se apresentou abaixo do descrito na literatura em alguns casos.

Published: May 2021

Introdução: As doenças cardiovasculares (DCVs) lideram o ranking de causas de mortes no Brasil e no mundo. No início do século XX, eram responsáveis por 10% das mortes mundiais, porém, no ano de 2013, já correspondiam a 31,5%. No Brasil, dados da Organização Mundial de Saúde (OMS), apontam que as DCVs causaram 31% das mortes no país em 2014, seguindo a média mundial. Objetivo: avaliar o nível de atividade física de pacientes no pré-operatório de cirurgia cardíaca através da aplicação do questionário. Métodos: O questionário de Baecke foi utilizado como instrumento de pesquisa em 20 pacientes cardiopatas, referidos para cirurgia de forma eletiva, com faixa etária igual ou acima de 30 anos, de ambos os sexos. Analisou-se o nível de atividade física destes pacientes a partir das respostas que deram para duas variáveis: Exercícios Físicos de Lazer (EFL); e Atividades de Lazer e Locomoção (ALL). A avaliação dessas variáveis quantitativas foi realizada pela correlação de Pearson. Como resultado, percebeu-se que 60% dos pacientes eram do sexo masculino, com idade média de 53±10 anos. A avaliação da interdependência entre os indicadores EFL e ALL realizada pela Correlação linear de Pearson resultou no p-valor 0.0001, o qual é altamente significante coeficiente de Correlação entre r = 0.8648, indicando forte correlação entre o EFL e o ALL. Conclusão: Pacientes em pré-operatório de cirurgia cardíaca são em sua maioria homens acima dos 50 anos que possuem um nível de condicionamento físico bom.
