Published: December 2020

INTRODUCCIÓN. En este trabajo pretendemos observar los efectos que tiene el aprendizaje cooperativo (AC) sobre una serie de variables que inciden directamente sobre el logro académico del alumnado. Concretamente, vamos a analizar sus efectos sobre la autoimagen de los chicos y chicas como estudiantes y su percepción del centro educativo en el que estudian. MÉTODO. Con este objetivo llevamos a cabo un estudio cuasiexperimental de grupos de control no equivalentes con pretest y postest, implicando a cuatro centros educativos de enseñanza secundaria caracterizados por su diversidad étnico-cultural. RESULTADOS. Realizamos distintos análisis estadísticos intra e intergrupo que apuntan a una mejora general en el rendimiento de los alumnos, si bien no de forma significativa. Esta mejora se explica por el efecto positivo del aprendizaje cooperativo sobre la autoimagen como estudiantes, la percepción del ambiente de aprendizaje en las clases y el sentimiento de protección y cuidado por parte del centro educativo. DISCUSIÓN. La introducción del aprendizaje cooperativo como estrategia de aula ayudará al docente a desarrollar una mayor creatividad y autonomía, ajustando determinados elementos de las técnicas a la realidad de su grupo. Por tanto, estas técnicas de aprendizaje constructivista redundarán no solo en beneficios para el alumnado, sino también para el profesorado, estableciendo diferentes canales comunicativos y simbólicos para la mejora de los procesos didácticos.

INTRODUCCIÓN. Factores como el rendimiento académico preuniversitario, el desarrollo de expectativas de resultados favorables, la información académica y el dominio de competencias básicas ayudan a predecir la integración social y académica del alumnado en la enseñanza universitaria. En este artículo se aborda el tema de las transiciones académicas, resaltando la importancia que tiene la orientación para ayudar a los jóvenes a preparar el acceso a los estudios universitarios. Las consecuencias que pueden derivarse de una mala transición vienen a destacar la importancia de la orientación en las etapas previas a la universidad. MÉTODO. En relación con este planteamiento, el objetivo del estudio es analizar la percepción que tiene una muestra de estudiantes de bachillerato respecto a distintos factores claves para afrontar la transición a la educación superior. Siguiendo un enfoque de investigación de corte cuantitativo basado en un estudio empírico-analítico que desarrolla una metodología ex post facto, se trabajó con una muestra representativa de 616 estudiantes de bachillerato de la provincia de Santa Cruz de Tenerife.RESULTADOS. Los resultados ponen de relieve que los estudiantes de bachillerato se perciben competentes para abordar las tareas académicas, muestran expectativas favorables de terminar con éxito sus estudios y destacan el apoyo de sus familiares y amigos a la hora de tomar decisiones. DISCUSIÓN. Los datos obtenidos constituyen un referente interesante para proponer actuaciones orientadoras de carácter preventivo, que sirvan para ayudar a los estudiantes a preparar la transición de la secundaria a la universidad. Para ello se requiere una mejor colaboración entre profesionales y la creación de redes de apoyo destinadas al seguimiento del alumnado a lo largo de su trayectoria académica.

Published: December 2020

The Acre and Rondônia states in Brazil are part of Western Amazon rainforest in Brazil, an area harboring high biodiversity and high degree of endemisms Nevertheless, there are few studies on diversity of social wasps occurring in both states. This study presents a list of social wasps (Vespidae: Polistinae) collected using three modified Malaise traps model: Townes, Gressit and Gressit, and suspended traps in two localities in Acre and two in Rondônia state. A total of 60 species were collected, 20 of these species are new distribution records to Acre state and 54 species, 15 of these species are new distribution records to Rondônia state. Some species are not commonly found in the collections and lists of species, and some are recorded for the first or second time to Brazil or the Amazon region. Now there are 114 species (19 genera) for Acre and 116 species (19 genera) for Rondônia. This increase may be an indication that the Polistinae richness is probably higher in the regions studied and that Acre and Rondônia may well contain a number of additional (as yet unrecorded) social wasp species. He we present an updated about the geographic records of social wasps’ fauna in both states.
Categorisation of myopia progression by change in refractive error and axial elongation and their impact on benefit of myopia control using orthokeratology
Authors: Cho Pauline , Cheung Sin Wan , Boost Maureen V. 
Published: December 2020

Aims
To compare the value of pre-treatment axial elongation (AE) and changes in refractive sphere (M change) for predicting the success in orthokeratology (ortho-k), in order to better identify suitable candidates for myopia control.

Methods
This study further analysed the data of 66 subjects receiving 7-month ortho-k treatment, following a 7-month observation period, during which single-vision spectacles were worn. Rate of myopia progression was determined by AE and M change and subjects categorised as slow, moderate, or rapid progressors based on these changes. Outcomes of myopia control, based on the AE reduction after ortho-k, were classified as ‘ineffectual’, ‘clinically insignificant’, or ‘beneficial’.

Results
Of the 20 subjects, initially categorised as slow by AE and, of whom 95% were similarly categorised by M change, none benefitted from ortho-k. In contrast, of the 22 subjects with moderate AE, 77% and 23% displaying slow and moderate M change, respectively, the majority (73%) benefitted from ortho-k lens wear. The 24 subjects with rapid AE were poorly identified by M change, with only 21% correctly categorised. The vast majority of rapid progressors showed significant benefit after ortho-k.

Conclusion
Progression of AE is a good indicator of subsequent success of ortho-k treatment. Delaying commencement of therapy is prudent for children with slow progression as results indicate that they would be unlikely to benefit from this intervention. As change in refractive error frequently underestimates rapid progression of AE, its value for identifying appropriate candidates for myopia control is poor.

Published: December 2020

Background
Studies from high-income countries reported reduced life expectancy in children with cerebral palsy (CP), while no population-based study has evaluated mortality of children with CP in sub-Saharan Africa. This study aimed to estimate the mortality rate (MR) of children with CP in a rural region of Uganda and identify risk factors and causes of death (CODs).

Methods and findings
This population-based, longitudinal cohort study was based on data from Iganga-Mayuge Health and Demographic Surveillance System in eastern Uganda. We identified 97 children (aged 2–17 years) with CP in 2015, whom we followed to 2019. They were compared with an age-matched cohort from the general population (n = 41 319). MRs, MR ratios (MRRs), hazard ratios (HRs), and immediate CODs were determined.
MR was 3952 per 100 000 person years (95% CI 2212–6519) in children with CP and 137 per 100 000 person years (95% CI 117–159) in the general population. Standardized MRR was 25·3 in the CP cohort, compared with the general population. In children with CP, risk of death was higher in those with severe gross motor impairments than in those with milder impairments (HR 6·8; p = 0·007) and in those with severe malnutrition than in those less malnourished (HR = 3·7; p = 0·052). MR was higher in females in the CP cohort, with a higher MRR in females (53·0; 95% CI 26·4–106·3) than in males (16·3; 95% CI 7·2–37·2). Age had no significant effect on MR in the CP cohort, but MRR was higher at 10–18 years (39·6; 95% CI 14·2–110·0) than at 2–6 years (21·0; 95% CI 10·2–43·2). Anaemia, malaria, and other infections were the most common CODs in the CP cohort.

Conclusions
Risk of premature death was excessively high in children with CP in rural sub-Saharan Africa, especially in those with severe motor impairments or malnutrition. While global childhood mortality has significantly decreased during recent decades, this observed excessive mortality is a hidden humanitarian crisis that needs to be addressed.

Published: December 2020

Purpose
Radiological assessment of primary brain neoplasms, both high (HGG) and low grade tumors (LGG), based on contrast-enhancement alone can be inaccurate. We evaluated the radiological value of amide proton transfer weighted (APTw) MRI as an imaging complement for pre-surgical radiological diagnosis of brain tumors.

Methods
Twenty-six patients were evaluated prospectively; (22 males, 4 females, mean age 55 years, range 26–76 years) underwent MRI at 3T using T1-MPRAGE pre- and post-contrast administration, conventional T2w, FLAIR, and APTw imaging pre-surgically for suspected primary/secondary brain tumor. Assessment of the additional value of APTw imaging compared to conventional MRI for correct pre-surgical brain tumor diagnosis. The initial radiological pre-operative diagnosis was based on the conventional contrast-enhanced MR images. The range, minimum, maximum, and mean APTw signals were evaluated.
Conventional normality testing was performed; with boxplots/outliers/skewness/kurtosis and a Shapiro–Wilk’s test. Mann-Whitney U for analysis of significance for mean/max/min and range APTw signal. A logistic regression model was constructed for mean, max, range and Receiver Operating Characteristic (ROC) curves calculated for individual and combined APTw signals

Results
Conventional radiological diagnosis prior to surgery/biopsy was HGG (8 patients), LGG (12 patients), and metastasis (6 patients). Using the mean and maximum: APTw signal would have changed the pre-operative evaluation the diagnosis in 8 of 22 patients (two LGGs excluded, two METs excluded). Using a cut off value of >2.0% for mean APTw signal integral, 4 of the 12 radiologically suspected LGG would have been diagnosed as high grade glioma, which was confirmed by histopathological diagnosis. APTw mean of >2.0% and max >2.48% outperformed four separate clinical radiological assessments of tumor type, P-values = .004 and = .002, respectively.

Conclusions
Using APTw-images as part of the daily clinical pre-operative radiological evaluation may improve diagnostic precision in differentiating LGGs from HGGs, with potential improvement of patient management and treatment.

Published: December 2020

Introduction
Reduced antiplatelet activity of aspirin (ALR) or clopidogrel (CLR) is associated with an increased risk of thromboembolic events. The reported prevalence data for low-responders vary widely and there have been few investigations in vascular surgery patients even though they are at high risk for thromb-embolic complications. The aim of this prospective observational monocentric study was to elucidate possible changes in ALR or CLR after common vascular procedures.

Methods
Activity of aspirin and clopidogrel was measured by impedance aggregometry using a multiple electrode aggregometer (Multiplate®). Possible risk factors for ALR or CLR were identified by demographical, clinical data and laboratory parameters. In addition, a follow-up aggregometry was performed after completion of the vascular procedure to identify changes in antiplatelet response.

Results
A total of 176 patients taking antiplatelet medications aspirin and/or clopidogrel with peripheral artery disease (PAD) and/or carotid stenosis (CS) were included in the study. The prevalence of ALR was 13.1% and the prevalence of CLR was 32% in the aggregometry before vascular treatment. Potential risk factors identified in the aspirin group were concomitant insulin medication (p = 0.0006) and elevated C-reactive protein (CRP) (p = 0.0021). The overall ALR increased significantly postoperatively to 27.5% (p = 0.0006); however, there was no significant change in CLR that was detected. In a subgroup analysis elevation of the platelet count was associated with a post-procedure increase of ALR incidence.

Conclusion
The incidence of ALR in vascular surgery patients increases after vascular procedures. An elevated platelet count was detected as a risk factor. Further studies are necessary to analyse this potential influence on patency rates of vascular reconstructions.

Published: December 2020

The aim of this study was to determine the effect of the age of trees, daily sap volume as well as the term of tapping birch sap collected in the forest environment on the content of selected minerals (zinc, copper and manganese) and heavy metals (lead, nickel, chromium and cadmium). The study was performed on material taken from two stands (aged 34 and 84 years) in a moist broadleaved forest habitat with a dominant share of silver birch (Betula pendulaRoth).The research results confirmed the presence of both nutritional essential minerals and hazardous heavy metals in the birch sap. At the same time, the content of minerals and heavy metals was found to be very variable and the differences between their concentrations, recorded on the same day of collecting in several trees of the same age group, can be even several dozen times higher. Depending on the examined elements, the factors influencing their content vary. The age of the trees determines only the manganese content; daily sap volume significantly affects the content of manganese and copper, and date of collection differentiates the content of zinc, lead, nickel and cadmium.The results may be interesting in the context of developing procedures for collecting birch sap for the purpose of obtaining raw material with beneficial nutritional values and a high level of health safety. For this reason, our recommendation for guaranteeing the health safety and high nutritional value of birch sap is to combine batches of raw material taken from as many trees as possible, and at the same time to publicize the fact that collecting birch sap from just one single tree may result in a raw material that is both dangerous and has no nutritional benefits.

Background
Real-world clinical data on psoriasis patients receiving different biological agents is needed, especially in Asian populations.

Objectives
Our aim is to compare and analyze the efficacy and safety profile of four biological agents (etanercept, adalimumab, ustekinumab and secukinumab) in a real-world setting in Taiwan.

Methods
We retrospectively analyzed the clinical data of all patients with moderate-to-severe plaque psoriasis (Psoriasis Area and Severity Index (PASI) ≥ 10) who received etanercept, adalimumab, ustekinumab or secukinumab between January 2011 and December 2018 in a tertiary hospital in Taiwan.

Results
A total of 119 treatment episodes in 75 patients were included in this study. Ustekinumab was used in 49 treatment episodes, followed by secukinumab in 46 treatment episodes, adalimumab in 14 treatment episodes and etanercept in 10 treatment episodes. The proportion of the biologic-naïve was highest in etanercept (100%) and lowest in secukinumab (23.9%). The PASI-75, -90 and -100 were the highest in secukinumab (91.3%, 82.6%, 41.3%, respectively), followed by ustekinumab (79.6%, 44.9%, 16.3%), adalimumab (64.3%, 28.6%, 7.1%) and etanercept (50.0%, 30.0%, 0%). The rate of adverse events that required treatment was highest for secukinumab (15.2%), followed by adalimumab (14.3%), ustekinumab (8.2%), and etanercept (0%), including 4 cases of infections, 2 cases of cardiovascular diseases and 4 cases of cancers.

Conclusions
This real world data showed differential efficacy and safety of the four biological agents.

Published: December 2020

Resumo: A cervicalgia é considerada um dos mais incômodos problemas osteomusculares, e, apresenta grande impacto na qualidade de vida dos indivíduos. A dor em região cervical é um problema comum entre os estudantes universitários, uma vez que o vício postural no desenvolvimento de tarefas corriqueiras e uso indiscriminado dos eletrônicos têm sido considerados como fatores geradores dessa patologia. Nesse sentido, o objetivo deste estudo foi identificar a cervicalgia inespecífica em estudantes de fisioterapia de uma instituição privada do Sudoeste Baiano. Tratou-se de um estudo descritivo exploratório com abordagem quantitativa, cuja amostra foi não probabilística, constituída por 30 estudantes do curso de fisioterapia. Utilizou-se para a coleta de dados um formulário construído por três blocos, a saber informações sociodemográficas dos estudantes, escala funcional de incapacidade do pescoço de Copenhagen e a Escala Visual Analógica (EVA) para a categorização da dor. A análise dos dados foi realizada através do programa SPSS (StatisticalPackage for the Social Sciences), versão 21.0. O estudo constatou que a média de idade da amostra estudada foi de 24,67 (± 3,35) anos, com predominância do sexo feminino, onde 63,3% dos estudantes apresentaram a cervicalgia e a dor esteve presente em 50% dos avaliados. A postura na sala de aula, e durante as horas de estudo extraclasse, bem como a utilização de notebooks, smartfones e tablets foram os fatores mais citados como responsáveis pelas dores cervicais.

Published: December 2020

The study aimed to develop a valid and reliable measurement tool for determining the recreational flow experience. For this purpose, an item pool consisting of 18 items was created. In line with expert opinions, items that were not suitable for the structure of the scale were removed from the scale. The 12-item form was first applied to 542 people (336 males and 206 females; age =23.39±3.44), who were selected by purposeful sampling method, in order to determine the scale structure and to create the items. Exploratory factor analysis was carried out with the data obtained through the SPSS 23.0 package program. As a result of the analysis, a single factor with 9 items was determined that explained 53.986% of the total variance. Then, in order to verify the validity of the scale, a questionnaire study was applied to a new group with a total of 150 people ( age =30.09±8.69), 108 men and 42 women. Confirmatory factor analysis was performed using the data obtained with the AMOS 23.0 package program. It was determined that the result of confirmatory factor analysis fit the model data well. When the results obtained in the evaluation of the measurement model were evaluated as a whole, the Recreational Flow Experience Scale (RFES) consisting of 9 items and a single factor was defined with sufficient validity and reliability. Finally, the theoretical and practical implications for the research were discussed. ​Extended English summary is in the end of Full Text PDF (TURKISH) file.
