Adaptando estrategias pedagógicas a los estilos de aprendizaje en educación primaria y secundaria: un enfoque integrador

This study addresses the influence of learning styles on the effectiveness of pedagogical strategies in primary and secondary education. Utilizing a mixed approach that combines literature review, surveys, interviews with educators, and case study analysis, the diversity of learning styles in young students is highlighted, with an emphasis on the importance of adapting teaching methodologies. A varied preference for visual, auditory, kinesthetic, and reading/writing styles is observed. Despite the recognition of the need for adaptation by educators, significant challenges related to resource availability and teacher training are identified. The findings indicate that the implementation of adaptive strategies improves both academic performance and student satisfaction, underscoring the need for flexible pedagogical practices and ongoing training for teachers at early educational levels.Este estudio abordó la influencia de los estilos de aprendizaje en la eficacia de las estrategias pedagógicas en la educación primaria y secundaria.

Se observa una variada preferencia por estilos visuales, auditivos, kinestésicos y de lectura/escritura. A pesar del reconocimiento de la necesidad de adaptación por parte de los educadores, se identifican desafíos significativos relacionados con la disponibilidad de recursos y la formación docente. Los hallazgos indican que, la implementación de estrategias adaptativas, mejora tanto el rendimiento académico como la satisfacción estudiantil, subrayando la necesidad de prácticas pedagógicas flexibles y formación continua para docentes en niveles educativos tempranos

Perfil epidemiológico y molecular de pacientes con cáncer de pulmón en un centro oncológico referencial de Lima, Perú.

Background: According to GLOBOCAN estimates, in 2020, lung cancer was the second most frequent cancer and epidemiological information is needed in Latin American countries. The objective was to describe the epidemiological and molecular characteristics of lung cancer patients from a referral clinic in Lima, Peru. Material and methods: A retrospective cohort study was conducted to characterize the epidemiological and molecular profile of lung cancer patients attended at a referral cancer center in Peru during 2018 to 2021. Variables such as age, sex, histology, staging and mutation were reported. In the descriptive analysis, frequencies and percentages were shown for categorical variables. For numerical variables, the best measure of central tendency and dispersion was reported. Results: A total of 225 patients with a diagnosis of lung cancer were observed. EGFR gene mutation was the most frequently detected (45.3%); and within them exon 19 deletion (55.7%). The most frequent histological type was adenocarcinoma with 180 patients (85.7%). Of the total number of patients with EGFR mutation, 77.8% received treatment with a tyrosine kinase inhibitor (osimertinib, erlotinib, afatinib) and 15.9% received immunotherapy (pembrolizumab, atezolizumab, nivolumab). Conclusions: The predominant mutation was EGFR, the most frequent histologic type was adenocarcinoma and most patients received treatment with a tyrosine kinase inhibitor.Introducción: Según estimaciones del GLOBOCAN, en 2020, el cáncer de pulmón fue el segundo más frecuente y se necesita información epidemiológica en países latinoamericanos.

Effectiveness and safety of the bevacizumab and erlotinib combination versus erlotinib alone in EGFR mutant metastatic non-small-cell lung cancer: systematic review and meta-analysis

BackgroundThe EGFR gene encodes a protein that stimulates molecular pathways that allow the growth and development of the tumor microenvironment. The current preferred tyrosine kinase inhibitor (TKI) for the first-line treatment of EGFRm metastatic non-small cell lung cancer (NSCLC) is osimertinib. However, the combination of angiogenesis inhibitors and TKI has produced discordant results. We aimed to assess the effects of the bevacizumab and erlotinib combination in EGFRm metastatic NSCLC.MethodsUsing eligibility criteria focused on patients with EGFRm metastatic NSCLC treated with bevacizumab and erlotinib, we searched databases including clinical trial randomized studies and reviews published until April 15, 2023 in Medline (PubMed), Scopus, and Embase. Eight clinical trials (1,052 patients) were selected from 1,343 articles for quantitative and qualitative assessment. The risk of bias was assessed using the Cochrane Risk of Bias tool. Data were synthesized through random-effects meta-analysis.ResultsThe bevacizumab and erlotinib combination significantly improved the progression-free survival (PFS) (log(HR) = 0.63; 95% CI: 0.54–0.73, p < 0.001) and overall response ratio (ORR) (RR = 0.79; 95% CI, 0.64–0.97, p = 0.03). However, it did not improve the overall survival (log(HR) = 0.93; 95% CI, 0.78–1.10, p = 0.38) and was associated with higher serious adverse events (SAEs) (OR = 3.48; 95% CI, 1.76–6.88, p = 0.005). A subgroup analysis suggested similar benefits in different mutation subtypes and brain metastasis condition. The evidence is limited by a moderate risk of bias across studies and heterogeneity in the reporting of SAEs.ConclusionsThe bevacizumab and erlotinib combination significantly improved PFS and ORR in EGFRm metastatic NSCLC but were also associated with higher-grade (≥3) adverse events. These results suggest that while the combination therapy may enhance progression-free survival and overall response, it does not improve the overall survival and is associated with higher toxicity. Thus, the treatment should be personalized based on individual patient comorbidities. Further prospective trials are needed to validate these results.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/#searchadvanced, identifier CDR 42022364692

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Prevalence of Gene Rearrangements in Mexican Children with Acute Lymphoblastic Leukemia: A Population Study—Report from the Mexican Interinstitutional Group for the Identification of the Causes of Childhood Leukemia

Mexico has one of the highest incidences of childhood leukemia worldwide and significantly higher mortality rates for this disease compared with other countries. One possible cause is the high prevalence of gene rearrangements associated with the etiology or with a poor prognosis of childhood acute lymphoblastic leukemia (ALL). The aims of this multicenter study were to determine the prevalence of the four most common gene rearrangements [ETV6-RUNX1, TCF3-PBX1, BCR-ABL1, and MLL rearrangements] and to explore their relationship with mortality rates during the first year of treatment in ALL children from Mexico City. Patients were recruited from eight public hospitals during 2010–2012. A total of 282 bone marrow samples were obtained at each child’s diagnosis for screening by conventional and multiplex reverse transcription polymerase chain reaction to determine the gene rearrangements. Gene rearrangements were detected in 50 (17.7%) patients. ETV6-RUNX1 was detected in 21 (7.4%) patients, TCF3-PBX1 in 20 (7.1%) patients, BCR-ABL1 in 5 (1.8%) patients, and MLL rearrangements in 4 (1.4%) patients. The earliest deaths occurred at months 1, 2, and 3 after diagnosis in patients with MLL, ETV6-RUNX1, and BCR-ABL1 gene rearrangements, respectively. Gene rearrangements could be related to the aggressiveness of leukemia observed in Mexican children

sPlotOpen - An environmentally balanced, open-access, global dataset of vegetation plots

Motivation Assessing biodiversity status and trends in plant communities is critical for understanding, quantifying and predicting the effects of global change on ecosystems. Vegetation plots record the occurrence or abundance of all plant species co-occurring within delimited local areas. This allows species absences to be inferred, information seldom provided by existing global plant datasets. Although many vegetation plots have been recorded, most are not available to the global research community. A recent initiative, called 'sPlot', compiled the first global vegetation plot database, and continues to grow and curate it. The sPlot database, however, is extremely unbalanced spatially and environmentally, and is not open-access. Here, we address both these issues by (a) resampling the vegetation plots using several environmental variables as sampling strata and (b) securing permission from data holders of 105 local-to-regional datasets to openly release data. We thus present sPlotOpen, the largest open-access dataset of vegetation plots ever released. sPlotOpen can be used to explore global diversity at the plant community level, as ground truth data in remote sensing applications, or as a baseline for biodiversity monitoring. Main types of variable contained Vegetation plots (n = 95,104) recording cover or abundance of naturally co-occurring vascular plant species within delimited areas. sPlotOpen contains three partially overlapping resampled datasets (c. 50,000 plots each), to be used as replicates in global analyses. Besides geographical location, date, plot size, biome, elevation, slope, aspect, vegetation type, naturalness, coverage of various vegetation layers, and source dataset, plot-level data also include community-weighted means and variances of 18 plant functional traits from the TRY Plant Trait Database. Spatial location and grain Global, 0.01-40,000 m(2). Time period and grain 1888-2015, recording dates. Major taxa and level of measurement 42,677 vascular plant taxa, plot-level records. Software format Three main matrices (.csv), relationally linked
