Burnout in university students

In order to provide a better understanding and characterization of the nature of academic burnout in university students, a review of the concept, its evolution and extrapolation of the work context to the university academic context is performed. It is proposed its delimitation, differentiation and relationship with comorbid clinical conditions like depression and anxiety. Additionally, this paper reviews empirical research that establishes relationships of the academic burnout with the academic engagement, risk factors and protective, and its impact on mental health and academic performance of college studentsCon la finalidad de proporcionar una mayor comprensión y caracterización de la naturaleza del burnout académico en estudiantes universitarios, se realiza una revisión del concepto, su evolución y extrapolación del contexto laboral al académico universitario, y se propone su delimitación y relación con condiciones clínicas comórbidas como depresión y ansiedad. Adicionalmente, se revisa la investigación empírica que establece relaciones del síndrome con el engagement académico, factores de riesgo y de protección, y sus consecuencias en la salud mental y en el desempeño académico de los estudiantes universitarios

TOX3 rs3803662 Polymorphism Is Associated With Breast Cancer Protection In Northeastern Mexican Woman

Introduction: Low penetrance genes are involved in breast cancer (BC) and confer risk for the development of this neoplasia. Different single nucleotide polymorphisms (SNPs) associated with BC have been identified, such as rs3803662 (TOX3), which is related to estrogen receptors in European and African-American women. The contribution of this variant in the Mexican population is unknown. The objective of this study was to evaluate, through a case-control design, the association of the SNP rs3803662 (TOX3), with the risk of BC in women from northeastern Mexico. Methods: We included 434 cases and 228 controls. Genotyping was carried out using RFLPs. The SPSS 7.0 statistical program was used to determine the gene frequencies, the estimation of the relative risk (Odds ratio [OR]), and the Hardy-Weinberg equilibrium (EHW). Results: The homocygote (T/T) genotype of the SNP TOX3 rs3803662 was identified as a protective allele for BC (OR: 0.47, 95% CI: 0.29 - 0.78). Conclusions; The T allele of the SNP rs3803662 can be considered as a protective factor for BC from northeastern Mexico women

A scale of family functioning in colombian adolescents: Design and validation

Objetivo: Construir y validar una escala para la evaluación del funcionamiento familiar en adolescentes (EFFA). Método: La muestra fue de 657 adolescentes entre 14 y 18 años con una media de 16,55±1,4; 299 eran hombres (45,5 %) y 358 (54,5 %) mujeres. Se aplicó una escala tipo Likert de 26 ítems que evalúa cinco dimensiones del funcionamiento familiar. Se realizó análisis factorial confirmatorio con el uso del programa estadístico Lisrel 8.0. Resultados: La consistencia interna total del instrumento fue de 0,849, y las escalas mostraron alfas de Cronbach entre 0,698 y 0,873. Las correlaciones de los ítems con las dimensiones fluctuaron entre 0,192** y 0,859**. Se hallaron correlaciones significativamente altas entre las subescalas (0,400** a 0,960**). Se detectaron correlaciones significativas con otras medidas vinculadas con las dimensiones propuestas. Conclusión: El EFFA mostró indicadores adecuados de validez y confiabilidad para la evaluación del funcionamiento familiar en adolescentes colombianos.Objective: Construct and validate an evaluation scale of family functioning in adolescents (EFFA).

Epidemiological Algorithm and Early Molecular Testing to Prevent COVID-19 Outbreaks in a Mexican Oncologic Center

Introduction: Prevention strategies and detection of latent COVID-19 infections in oncology staff and oncologic patients are essential to prevent outbreaks in a cancer center. In this study, we used two statistical predictive models in oncology staff and patients from the radiotherapy area to prevent outbreaks and detect COVID-19 cases. Methods: Staff and patients answered a questionnaire (electronic and paper surveys, respectively) with clinical and epidemiological information. The data was collected through two online survey tools: Real-Time Tracking (R-Track) and Summary of Factors (S-Facts). According to the algorithm\u27s models, cut-off values were established. SARS-CoV-2 qRT-PCR tests confirmed the algorithm\u27s positive individuals. Results: Oncology staff members (n=142) were tested, and 14% (n=20) were positives for the R-Track algorithm; 75% (n=15) were qRT-PCR positive. The S-Facts algorithm identified 7.75% (n=11) positive oncology staff members, and 81.82% (n=9) were qRT-PCR positive. Oncology patients (n=369) were evaluated, and 1.36% (n=5) were positive for the algorithms. The 5 patients (100%) were confirmed by qRT-PCR at a very early stage. Conclusions: The proposed algorithms could prove to become an essential prevention tool in countries where qRT-PCR tests and vaccines are insufficient for the population

Risk Association of TOX3 and MMP7 Gene Polymorphisms with Sporadic Breast Cancer in Mexican Women

Breast cancer (BC) has one of the highest incidences and mortality worldwide. Single nucleotide polymorphisms (SNPs) in TOX3 rs3803662 and MMP7 rs1943779 have been associated with susceptibility to BC. In this case-control study, we evaluated the association of rs3803662 (TOX3)/rs1943779 (MMP7) SNPs with clinical features, immunohistochemical reactivity, and risk association with BC in women from northeastern Mexico. We compared 212 BC cases and 212 controls. DNA was isolated from peripheral blood to perform the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. We calculated genotype frequencies, odds ratios, and 95% confidence intervals. We found that CT (Cytocine-Thymine) and TT (Thymine -Thymine) genotypes, and T alleles of TOX3 rs3803662, were associated with BC risk (p = 0.034, p = 0.011, respectively). SNP TOX3 rs3803662 was associated with positive progesterone receptors (PR) and triple-negative BC (TNBC) but not with estrogen receptor (ER) or HER2 reactivity. CT and TT genotypes (p = 0.006) and T alleles (p = 0.002) of SNP MMP7 rs1943779 were associated with risk of BC. We found that T alleles of TOX3 rs3803662 and MMP7 rs1943779 SNPs are associated with BC risk. These findings contribute to personalized medicine in Mexican women

Despliegue de la función calidad para determinar los requisitos de diseño en biopilas experimentales a escala de banco, evaluadas como alternativa resiliente para la degradación de residuos petrolizados

Due to the increased amount of oil used, large volumes of hydrocarbons are released annually into the environment, constituting one of the main causes of soil pollution worldwide. The Center for Environmental Studies of Cienfuegos, Cuba, implemented an experimental project to develop an innovative technique that increases territorial resilience to this environmental problem. The goal was to implement the Quality Function Deployment (QFD) to determine the design requirements of the experimental units to evaluate at the bench-scale during the degradation of oily residues through different treatments of biopiles ecotechnology. A 4-stage approach allowed for organizing the team, selecting the technology, adopting a QFD implementation procedure to translate the needs into engineering requirements, and disseminating the results. The concentrations of microorganisms, nutrients, and hydrocarbons in the biopile were the characteristics that accumulated more than 50% of the relative weights of the first level matrix. The initial concentration of hydrocarbons and the percentages of moisture and bulking agents in the mixture obtained the highest relative weights in the second level. The percentage of bulking agents in the biopile mixture was identified as an opportunity to reduce costs and improve the effectiveness of bioremediation. The results enabled the delineation of the experimental protocols for the engineering design, which allowed to build off a bench-scale prototype of the experimental units for evaluating various treatments of biopiles ecotechnology as a resilient alternative against soil hydrocarbon pollution
