The Impact of Social Media Use for News on Academic Performance in Underrepresented Undergraduate College Students.

Researchers have demonstrated that the relationship between social media use (SMU) and academic performance is mixed. This study extends those findings by examining how SMU for news predicts grade point average (GPA) for Hispanic, Black/African American, and White college students while controlling for gender. Students (N = 378) completed surveys where they reported how many times per week they used various social media platforms for news, whether or not they used those platforms to consume certain types of news, and demographic information. For Hispanic students, results indicated that using YouTube for entertainment news predicted lower GPAs, whereas using YouTube for news predicted higher GPAs. Black/African American students' use of Facebook for news predicted lower GPAs. SMU for news for White students did not predict GPA. Findings indicate that race/ethnicity should be considered when examining the relationship between SMU and academic performance and that minority students' GPAs are affected by their use of social media for news.

Ischemic Stroke During Dengue Infection: A Report of 2 Cases.

BACKGROUND Involvement of the central nervous system during infection with dengue virus (DENV) is recognized. However, ischemic stroke is rarely reported. Herein are described 2 cases of patients with ischemic stroke in which DENV infection was demonstrated. CASE REPORT The first patient was a 51-year-old woman that presented altered consciousness, monoparesis, facial palsy, dysarthria, Babinski sign, and syncope 7 days from the onset of fever. She had a history of carotid artery atherothrombosis and previous stroke. Magnetic resonance imaging (MRI) showed an acute infarction of the right middle cerebral artery. DENV was confirmed by the presence of NS1 and IgM in serum. The patient was treated with intravenous fluids and recovered well, with only right facial paresis still present at discharge. The second patient was a 50-year-old man who presented with headache, altered consciousness, and mutism after a febrile episode 1 week prior. This patient had a previous history of stroke, glioblastoma resection, epilepsy, hypothyroidism, and diabetes. MRI demonstrated a subacute ischemic event. The diagnosis of dengue was confirmed by serum NS1 and IgM and by RT-PCR in serum and cerebrospinal fluid. DENV-1 serotype was observed in serum and cerebrospinal fluid. The patient was treated with intravenous fluids and was discharged in good condition. In both patients, thrombocytopenia and leukopenia was demonstrated, and hemoconcentration was demonstrated in the second patient. CONCLUSIONS In tropical and subtropical countries, DENV infection can represent a potential cause of ischemic stroke in patients with a history of comorbidities, including stroke.

Use of community resources as health assets for rehabilitation of people with Long COVID in northeastern Spain two years after the outbreak of the COVID-19 pandemic: qualitative study.

INTRODUCTION: The epidemiology of Post COVID Condition is not yet known. There are different treatment options, but they are not recommended or suitable for all those affected. For this reason and due to the lack of health treatment, many of these patients have tried to carry out their own rehabilitation through the use of community resources. OBJECTIVE: The objective of this study is to deepen into the understanding about the use of community resources as assets for health and rehabilitation by people with Long COVID and their utility. METHODOLOGY: A qualitative design was carried out with the participation of 35 Long COVID patients, of which 17 subjects were interviewed individually and 18 of them were part of two focus groups. The participating patients were recruited in November and December 2021 from the Primary Health Care centers and through the Association of Long COVID patients of Aragon. The research topics were the use of community resources, before and after their infection by COVID-19, rehabilitation through their use, as well as barriers and strengths for their employment. All analyses were performed iteratively using NVivo software. RESULTS: Long COVID patients who have used community resources for rehabilitation have seen an improvement in their physical and mental health. Most of them, specifically those affected, have used green spaces, public facilities, physical or cultural activities and associations. The main barriers identified have been the symptoms themselves and the fear of reinfection, with the main advantage of these activities being the perceived health benefits. CONCLUSION: The use of community resources seems to be beneficial in the recovery process of Long COVID patients, so it is necessary to continue delving into this topic and promote the formal use of the Recommendation of Health Assets from Primary healthcare.

Prevalence of neuromyelitis optica spectrum disorder in antioquia between 2016 and 2018.

BACKGROUND: There are few epidemiological studies published in the world evaluating the prevalence of Neuromyelitis Optica Spectrum Disorder (NMOSD). The true prevalence of the disease is not known and the studies carried out are based on the diagnostic criteria used prior to 2015. OBJECTIVE: To determine the prevalence of NMOSD in Antioquia, from January 2016 to December 2018. METHODS: The prevalence of NMOSD in Antioquia was determined using the Capture-Recapture Method. Eight centers in the Department of Antioquia for the care of patients with neurological diseases were included. The data was collected between 2016 and 2018. RESULTS: A total of 221 consultation histories, 169 patients with a diagnosis of NMOSD were identified. The prevalence was 4.03 cases/100,000 inhabitants (95% confidence interval (CI) 3.3-4.8) of whom (87.5%), were women and the predominant race was Mestizo (81.6%). The most frequent initial presentation was optic neuritis (ON) (50.9%). Most of the patients had motor or visual disability (86.4%) and the treatment most used was Rituximab (47.9%). CONCLUSION: The prevalence of NMOSD in Antioquia is one of the highest reported in the world, except for the French Antilles. More studies are required to know the prevalence of this disease in the Colombian population.

Gestational phthalate exposure and lung function during childhood: A prospective population-based study.

The potential effect of gestational exposure to phthalates on the lung function levels during childhood is unclear. Therefore, we examined this association at different ages (from 4 to 11 years) and over the whole childhood. Specifically, we measured 9 phthalate metabolites (MEP, MiBP, MnBP, MCMHP, MBzP, MEHHP, MEOHP, MECPP, MEHP) in the urine of 641 gestating women from the INMA study (Spain) and the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and FEV1/FVC in their offspring at ages 4, 7, 9 and 11. We used linear regression and mixed linear regression with a random intercept for subject to assess the association between phthalates and lung function at each study visit and for the overall childhood, respectively. We also assessed the phthalate metabolites mixture effect on lung function using a Weighted Quantile Sum (WQS) regression. We observed that the phthalate metabolites gestational levels were consistently associated with lower FVC and FEV1 at all ages, both when assessed individually and jointly as a mixture, although most associations were not statistically significant. Of note, a 10% increase in MiBP was related to lower FVC (-0.02 (-0.04, 0)) and FEV1 z-scores (-0.02 (-0.04, -0.01) at age 4. Similar significant reductions in FVC were observed at ages 4 and 7 associated with an increase in MEP and MnBP, respectively, and for FEV1 at age 4 associated with an increase in MBzP. WQS regression consistently identified MBzP as an important contributor to the phthalate mixture effect. We can conclude that the gestational exposure to phthalates was associated with children's lower FVC and FEV1, especially in early childhood, and in a statistically significant manner for MEP, MiBP, MBzP and MnBP. Given the ubiquity of phthalate exposure and its established endocrine disrupting effects in children, our findings support current regulations that limit phthalate exposure.

The Tracking of Moist Habitats Allowed Aiphanes (Arecaceae) to Cover the Elevation Gradient of the Northern Andes.

The topographic gradients of the Tropical Andes may have triggered species divergence by different mechanisms. Topography separates species' geographical ranges and offers climatic heterogeneity, which could potentially foster local adaptation to specific climatic conditions and result in narrowly distributed endemic species. Such a pattern is found in the Andean centered palm genus Aiphanes. To test the extent to which geographic barriers and climatic heterogeneity can explain distribution patterns in Aiphanes, we sampled 34 out of 36 currently recognized species in that genus and sequenced them by Sanger sequencing and/or sequence target capture sequencing. We generated Bayesian, likelihood, and species-tree phylogenies, with which we explored climatic trait evolution from current climatic occupation. We also estimated species distribution models to test the relative roles of geographical and climatic divergence in their evolution. We found that Aiphanes originated in the Miocene in Andean environments and possibly in mid-elevation habitats. Diversification is related to the occupation of the adjacent high and low elevation habitats tracking high annual precipitation and low precipitation seasonality (moist habitats). Different species in different clades repeatedly occupy all the different temperatures offered by the elevation gradient from 0 to 3,000 m in different geographically isolated areas. A pattern of conserved adaptation to moist environments is consistent among the clades. Our results stress the evolutionary roles of niche truncation of wide thermal tolerance by physical range fragmentation, coupled with water-related niche conservatism, to colonize the topographic gradient.

Association between phenols and thyroid hormones: The role of iodothyronine deiodinase genes.

Previous literature on prenatal phenol exposure and thyroid hormone (TH) alteration is conflicting, and the possible mechanisms of action involved remain unclear. We aimed to examine the association between prenatal phenol exposure and levels of maternal and neonatal THs, as well as the possible role of iodothyronine deiodinase (DIO) gene polymorphisms in this relation. We studied 387 Spanish mother-neonate pairs with measurements of maternal phenols, total triiodothyronine (TT3) and free thyroxine (FT4), maternal and neonatal thyroid-stimulating hormone (TSH), and maternal genotypes for single nucleotide polymorphisms in the DIO1(rs2235544) and DIO2(rs12885300) genes. We implemented multivariate linear and weighted quantile sum (WQS) regressions to examine the association between phenols and THs (including sex-stratified models for neonatal TSH) and investigated effect modification of genotypes in the maternal phenol-TH associations. In single exposure models, we found negative associations between maternal triclosan (TCS) and neonatal TSH (% change [95%CI]: -2.95 [-5.70, -0.11], per twofold phenol increase) - stronger for girls - and less clearly for maternal ethylparaben (EPB) and TSH (-2.27 [-4.55, 0.07]). In phenol mixture models, we found no association with THs. In the genetic interaction models, we found some evidence of effect modification of DIO gene polymorphisms with stronger negative associations between methylparaben (MPB), propylparaben (PPB), butylparaben (BPB) and TT3 as well as bisphenol A (BPA) and FT4 for DIO1(rs2235544)-CC. Stronger inverse associations for genotypes DIO2(rs12885300)-CC and DIO2(rs12885300)-CT and positive ones for DIO2(rs12885300)-TT were also reported for BPA and FT4. In conclusion, we found some evidence of an association between phenols and TSH during pregnancy and at birth in single exposure models, the latter being stronger for girls. Since no association was observed between maternal levels of phenols and TT3 or FT4, the possible role of the genetic background in these associations warrants further investigation.

[Degree of satisfaction of dental students regarding the use of educational games during the COVID-19 pandemic]. / Grado de satisfacción de estudiantes de odontología respecto al empleo de juegos didácticos en tiempos de pandemia por COVID-19.

Objetive: To determine the degree of student satisfaction regarding the use of didactic games in Infantile Odontology I at the School of Dentistry of the Costa Rica University. Methods: This was a descriptive study with a qualitative approach. Five didactic games were created using the Educaplay application and were implemented alternately: evaluation of cariogenic risk, general pathology of children, early childhood cries, dental remineralization and anatomy of temporal pieces. At the end of the course, a survey was sent by institutional mail to the 52 students to assess the use of the games. Results: 38 students answered the survey, with 97.4% considering the didactic games useful or very useful in the lessons. Furthermore, 65.8% indicated that the games had greatly helped to improve learning and 71.1% stated that the classes in which the game was applied were more dynamic. In addition, 92.1% of the respondents would like this dynamic to be implemented in other courses. Conclusions: The students of Infantile Odontology I reported a high degree of satisfaction regarding the use of didactic games during the lessons, describing that the games maintain motivation.

Terminal efficiency, Lag and dropout in cohorts from 2007 to 2014 of dental students at the University of Costa Rica / Eficiencia terminal, rezago y abandono en las cohortes del 2007 al 2014 de estudiantes de Odontología de la Universidad de Costa Rica

Abstract Determine the terminal efficiency, lag and dropout in the cohorts of students who entered the dentistry career at the Faculty of Dentistry at University of Costa Rica in the lapse 2007 to 2014. Data from 736 files were collected. The variables considered were sex, admission age, nationality, marital status, children, admission note, domicile and high school. The data was collected from the Student Application System, the physical files, and the data base from the Supreme Court of Elections of Costa Rica. Descriptive statistics, bivariate and multivariate analysis were made, which were implemented from two logistic regression models. 98% of the students were Costa Rican, 68% women, 79% entered according to the admission note, 43% entered with an age of 18 years or less, 50% came from a public school, 77% resided in the Greater Metropolitan Area and 95% were single and remained without children. The average terminal efficiency was 6%; 46% of students have graduated with lag, 16% are still enrolled and 32% dropped out. Sex, age, admission note, and motherhood are sociodemographic variables that are associated with terminal efficiency and dropout. The average terminal efficiency in the cohorts from 2007 to 2014 in the courses at the Faculty of Dentistry University of Costa Rica was very low, almost half of the students graduated with lag and about a third dropped out the studies. The grade from the admission note seems to be a predictor of students'academic behavior, higher grade had more chances of graduating and less likely to dropout.

La nota del examen de admisión parece ser un predictor en el comportamiento académico de los estudiantes: a mayor nota más posibilidades de graduarse y menos de abandonar la carrera.

Patient satisfaction regarding biosecurity protocols in the face of COVID-19, Faculty of Dentistry, University of Costa Rica / Satisfacción de los pacientes respecto a los protocolos de bioseguridad ante el COVID-19, Facultad de Odontología, Universidad de Costa Rica

Abstract Biosecurity protocols are particularly important in dental practice. The aim of this research was to determine the level of patient satisfaction regarding biosecurity protocols used in the School of Dentistry of the University of Costa Rica, to avoid COVID-19 infections during dental care. A survey was sent by email to all patients who received dental consultations at the School of Dentistry between April and September 2021. They were asked about sociodemographic variables (sex, age range, approved educational level, and place of origin), as well as whether they considered safe the protocols used during the dental consultation to avoid COVID-19 infections. Descriptive statistics were performed proving the absolute and relative frequency of the socio-demographic variables and the satisfaction of patients with the protocols used. A Chi-square test was used to determine if there was a difference in patient satisfaction with biosecurity protocols to avoid COVID-19 infections during dental care and sociodemographic variables. 95.9% of the respondents considered the biosafety protocols used to be safe and there was no statistically significant difference between patient satisfaction with the protocols and sociodemographic variables. A large majority of patients who come to the UCR School of Dentistry are satisfied with the biosecurity protocols used to avoid COVID-19 infections during dental care.

Conocimiento acerca del manejo inmediato del trauma dental en un grupo de docentes de preescolar y primaria en Costa Rica / Immediate management dental trauma knowledge of preschool and primary school teachers in Costa Rica

Objetivo. Determinar el grado de conocimiento en el manejo inmediato del trauma dental en los profesores de preescolar y primaria en la provincia de Cartago en Costa Rica. Métodos. Se realizó un estudio observacional de corte transversal en el que se aplicó una encuesta enviada vía correo electrónico a un grupo de docentes. Se incluyeron variables sociodemográficas y de conocimiento referente a la atención del trauma dental en niños/as. El total de instituciones participantes fue de 11 (6 públicas y 5 privadas). La encuesta fue respondida por 60 docentes de instituciones públicas y 141 de centros privados. Se creó un puntaje de conocimiento, asignando 1 punto para las respuestas correctas y 0 puntos para las respuestas incorrectas. Las puntuaciones mayores a 4 fueron consideradas como "conocimiento adecuado" acerca del trauma dental y su manejo. Se realizó una estadística descriptiva de las variables y la prueba de chi cuadrado para determinar si existía diferencia en el grado de conocimiento de los docentes respecto a la atención inmediata del trauma dental según las variables sociodemográficas. Resultados. Solo un 24% de los docentes obtuvo una puntuación superior a 4. Además, se encontró una relación estadísticamente significativa entre algunas variables: a mayor edad, mayor experiencia docente y haber sido testigo de situaciones de trauma dental, mayor es el conocimiento de los docentes en esta área. Conclusiones. Los docentes de preescolar y primaria del Circuito 1 de la provincia de Cartago poseen, en su mayoría, un bajo conocimiento para la atención inmediata del trauma dental

Objective. To determine the degree of knowledge in the immediate management of dental trauma in preschool and primary school teachers in the province of Cartago in Costa Rica. Methods. A cross-sectional observational study was performed. An electronic survey was sent via email to a group of teachers. Sociodemographic and knowledge variables regarding dental trauma care in children were included. Eleven schools participated in the study (6 public and 5 private). The survey was answered by 60 teachers from public institutions and 141 from private schools. A knowledge of score was created, assigning 1 point for correct answers and 0 points for incorrect answers Scores greater than 4 were considered as "adequate knowledge" about dental trauma and its management. Descriptive statistics of the variables and the chi-square tests were performed to determine if there was a difference in the degree of knowledge of the teachers regarding the immediate care of dental trauma according to the sociodemographic variables. Results. Only 24% of the teachers obtained a score higher than 4. In addition, a statistically significant relationship was found between some variables: the older they are, the more experienced they are in teaching, and having witnessed situations of dental trauma, the greater the knowledge of the teachers in this area. Conclusions. Preschool and primary teachers of Circuit 1 of the province of Cartago have, mostly, little knowledge for the immediate care of dental trauma.

Paramolares bilaterales maxilares no erupcionados y su abordaje quirúrgico: reporte de un caso inusua / Paramolares bilaterais superiores não erupcionados e sua abordagem cirúrgica: relato de caso incomun / Non-erupted maxillary bilateral paramolars and their surgical approach: unusual case report

El término dientes supernumerarios se refiere al exceso en el número normal de dientes ya sea en la dentición primaria como en la permanente, pueden presentarse de forma única o múltiple, unilateral o bilateral, tanto en maxilar como en mandíbula. Un paramolar es un molar supernumerario generalmente rudimentario ubicado en posición vestibular o palatino de uno de los molares o en el espacio interproximal al segundo y tercer molar. Su prevalencia es menor al 0,20%, se presentan más en hombres que en mujeres y generalmente se encuentran erupcionados. En el presente artículo se reporta el caso inusual de una paciente femenina con paramolares maxilares bilaterales no erupcionados los cuales fueron removidos quirúrgicamente sin complicaciones

A O termo dentes supranumerário se refere ao excesso no número normal de dentes, seja na dentição decídua ou permanente, podendo ocorrer de forma única ou múltipla, unilateral ou bilateral, tanto na maxila quanto na mandíbula. Um paramolar é um molar supranumerário geralmente rudimentar localizado na posição vestibular ou palatina de um dos molares ou no espaço interproximal do segundo e terceiro molares. Sua prevalência e inferior a 0,20%, ocorrem mais em homens do que em mulheres e geralmente surgem. Neste artigo, relatamos o caso incomum de uma paciente do sexo feminino com paramolares superiores bilaterais não erupcionados, que foram removidos cirurgicamente sem complicações

The term supernumerary teeth refer to the excess in the normal number of teeth, either in the temporary or in the permanent dentition, it can appear in a single or multiple forms, unilateral or bilateral, both in the maxilla and in the mandible. A paramolar is a generally rudimentary supernumerary molar located in the vestibular or palatal position of one of the molars or in the space interproximal to the second and third molars. Prevalence is less than 0,2%, they are more frequent in men than in women and are generally erupted. This article reports the unusual case of a female patient with unerupted bilateral maxillary paramolars which were surgically removed without complications

Corrective Treatment of Ectopic Eruption of Permanent First Molars: Case Report / Tratamiento correctivo de erupción ectópica de primeros molares permanentes: Reporte de casos

ABSTRACT: Ectopic eruption of a tooth is the process in which a tooth emerges in an abnormal position. The first permanent molar is the tooth that most frequently presents ectopic eruption, mostly because it is retained below the distal contour of the second temporary molar. The ectopic eruption may be reversible or irreversible, the latter of which requires corrective treatment to achieve correct eruption of the permanent molar in the arch. Treatments can be minimally invasive, such as the use of interproximal wedging, or more invasive orthodontic devices, such as brass wire, k-loops, Halterman devices, or wedging springs. The aim of this case report is to present two clinical cases where the ectopic eruption of permanent first molars is corrected using elastic separators. Conclusion:The elastic separators could be used successfully in cases of moderate or severe ectopic eruptions, not only in mild cases, as reported in most of the literature. The use of this technique does not require great cooperation from the patient, and it is low in cost.

RESUMEN: La erupción ectópica de un diente es el proceso por el cual el diente emerge en una posición anormal. La primera molar permanente es el diente que más frecuentemente presenta erupción ectópica, ya que, en su proceso de erupción, queda retenida debajo del contorno distal de la segunda molar temporal. La erupción ectópica puede ser reversible o irreversible, si es irreversible requiere tratamiento correctivo para lograr que la molar permanente erupciones correctamente en el arco. Los tratamientos pueden ser poco invasivos como el uso de separados elásticos o más invasivos con aparatos ortodóncicos tales como brass wire, k-loop, Halterman o wedging spring. El objetivo del presente artículo es presentar dos casos clínicos donde se corrige la erupción ectópica de primeros molares permanentes utilizando separadores elásticos. Conclusión: los separadores elásticos pueden usarse con éxito en casos de erupciones ectópicas moderadas o severas, no sólo en casos leves como reporta la mayoría de la literatura. El uso de esta técnica no requiere gran cooperación por parte del paciente y es de bajo costo económico.

Age and sequence of emergence of permanent teeth in a population of Costa Rican school children / Edad y secuencia de erupción de la dentición permanente en una población de niños escolares en Costa Rica

ABSTRACT: The aim of this study was to determine the average age and sequence of eruption of permanent dentition in the school population of the province of Cartago, Costa Rica. Methods: A cross-sectional observational study included children between the ages of 5 and 12 from public and private schools. Clinical examination was performed, and the presence or absence of permanent teeth recorded. Statistical analysis: An estimation of means of eruption was used through binary variables, building the probabilities of the presence of a dental piece through a logistic regression. Results: 833 children were examined: 433 (51.90%) girls and 400 (48.10%) boys. The permanent teeth erupt first in the female sex; however, this difference is not statistically significant. The maxilla eruption sequence for girls was 6-1-2-4-3-5-7 on both sides; for boys, the sequence of eruption was 6-1-2-4-5-3-7 for the right side and 6-1-2-4-3-5-7 for the left side. In the jaw, the sequence in boys was 6-1- 2-3-4-5-7, and in girls, 1-6-2-3-4-5-7. Conclusions: For the first time, at the Central American Level, the pattern of permanent dentition eruption could be established. The age of permanent dental eruption does not vary according to sex in this population.

RESUMEN: El objetivo de este estudio fue determinar la edad promedio y la secuencia de erupción de la dentición permanente en la población escolar de la provincia de Cartago, Costa Rica. Metodología: se realizó un estudio transversal que incluyó niños con edades comprendidas entre los 5 y 12 años provenientes de escuelas públicas y privadas. Se realizó un examen clínico y se registró la presencia o ausencia de dientes permanentes. Análisis estadístico: se utilizó una estimación de las medias de erupción a través de variables binarias, construyendo las probabilidades de la presencia de una pieza dental por medio de una regresión logística. Resultados: se examinaron 833 sujetos: 433 (51,90%) niñas y 400 (48,10%) niños. Los dientes permanentes erupcionaron primero en el sexo femenino, sin embargo, esa diferencia no fue estadísticamente significativa. La secuencia de erupción maxilar para las niñas fue 6-1-2-4-3-5-7 en ambos lados; para los niños la secuencia fue 6-1-2-4-5-3-7 para el lado derecho y 6-1-2-4-3-5-7 para el lado izquierdo. En la mandíbula, la secuencia en los niños fue de 6-1-2-3-4-5-7-, y en las niñas fue de 1-6-2-3-4-5-7. Conclusiones: por primera vez a nivel de Centroamérica se pudo establecer el patrón de erupción de la dentición permanente. La edad de erupción dental permanente no varía según el sexo en esta población.
