Factores que determinan la transferencia de conocimientos en los estudiantes de la carrera de Ingeniería Comercial

La investigación está orientada a determinar los factores que limitan la transferencia de conocimiento a los estudiantes de la Carrera de Ingeniería Comercial. El objetivo del proyecto es mostrar los factores influyentes en la transferencia del conocimiento porque se ha observado que existe deficiencia en los conocimientos adquiridos en las diferentes asignaturas de parte de los estudiantes de la carrera. Para conocer más a fondo esta problemática, se realizó la investigación desde un punto de vista científico, teórico, técnico, y de investigación de campo directamente con los actores. La metodología para la realización del estudio fue aplicar una encuesta a docentes y estudiantes, para la recolección de información, con la cual se obtuvo información valiosa aplicado mediante una encuesta a los estudiantes de los últimos niveles y a los docentes de la carrera, para poder determinar los factores que están presentes en la transferencia del conocimiento, luego de tabular los datos se observa que los principales factores son: la relación entre estudiantes y docentes, la comunicación afectiva y el aprendizaje activo, siendo el aprendizaje activo el que tiene mayores inconvenientes tanto desde la perspectiva de docentes y estudiantes, los motivos que permitieron llegar a este consenso son que las dos partes tienen claramente identificado que las clases deben ser en gran parte de forma práctica y menos teóricas, los estudiantes manifestaron de igual manera problemas con la relación que existe entre docente y estudiante

Normative Anthropometric and Physical-Function Scores for Costa Rican Older Adults

INTRODUCTION: The aging population is becoming significantly large in several countries due to improved health conditions and higher life expectancy. For instance, Costa Rican elderly have 17% less mortality at 90 yr. of age than elderly from high-income countries, and in Costa Rica life expectancy is higher for men than for women. In developed countries such as Spain, a large number of sedentary elderly have been found with elevated body fat percentage, which might impact their overall health and quality of life. Although the international scientific literature is extensive, the physical and functional status of Central American elderly is unknown. PURPOSE: The purpose of the study was to construct normative scores for anthropometric, adiposity and upper-arm strength variables in Costa Rican adults aged 60 to 110 yr. METHODS: Participants were 5494 Costa Rican elderly randomly selected from the Costa Rican National Population Census. These participants were assessed to determine their general health status and to obtain anthropometric, adiposity and hand grip strength measures. RESULTS: Nearly 50% of males and females showed an increased risk of metabolic complications (χ2 = 91.6; p ≤ 0.001). A higher percentage of females (64.5%) had abdominal obesity compared to males (18.6%). Males (39.8%) were more pre-obese than females (37.2%) and also type II obesity was more frequent in males (3.8%) than in females (3.5%). Males had higher body weight (4.4%) than females (3.9%), less type I obesity (13.4%) than women (17.5%) and less type III obesity (1.0%) than females (1.5%). Gender specific percentile-based norms (P10th, P25th, P50th, P75th, and P90th) were derived from data collected for each 10-year age groups (60-69, 70-79, 80-89, 90-99, and ≥100). CONCLUSION: This is the first population-based study in Central America reporting normative scores for anthropometric and physical-function variables in older adults

Effects of Supervised Cardiac Rehabilitation Programmes on Quality of Life among Myocardial Infarction Patients: A Systematic Review and Meta-Analysis

Coronary heart disease is the leading cause of death and disability worldwide. Traditionally, cardiac rehabilitation programmes are offered after cardiac events to aid recovery, improve quality of life, and reduce adverse events. The objective of this review was to assess the health-related quality of life, after a supervised cardiac rehabilitation programme, of patients who suffered a myocardial infarction. A systematic review was carried out in the CINAHL, Cochrane, LILACS, Medline, Scopus, and SciELO databases, according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. Randomised controlled trials were selected. Meta-analyses were performed for the Short Form Health Survey SF-36, Myocardial Infarction Dimensional Assessment Scale (MIDAS), MacNew Heart Disease-Health-Related Quality of Life (HRQL) questionnaire, and European Quality of Life-Visual Analogue Scale (EuroQol-VAS) with the software Cochrane RevMan Web. Ten articles were found covering a total of 3577 patients. In the meta-analysis, the effect size of the cardiac rehabilitation programme was statistically significant in the intervention group for physical activity, emotional reaction, and dependency dimensions of the MIDAS questionnaire. For the control group, the score improved for SF-36 physical functioning, and body pain dimensions. The mean difference between the control and intervention group was not significant for the remaining dimensions, and neither for the MacNew Heart Disease-HRQL and EuroQol-VAS questionnaires. Supervised cardiac rehabilitation programmes were effective in improving health-related quality of life, however, there was a potential variability in the interventions; therefore, the results should be interpreted with caution. This study supports the importance of providing care and evaluating interventions via the supervision of trained health professionals, and further randomised clinical trials are needed to analyse the positive changes in mental and physical health outcomes

Síndrome de Mirizzi grado IV. Presentación de un caso

El Síndrome de Mirizzi es una afección derivada del impacto de un lito en el conducto cístico o infundíbulo de la vesícula biliar. La enfermedad litiásica, crónica y complicada de la vesícula biliar es un factor determinante. Se presenta el caso de un paciente con historia de íctero obstructivo, al cual se le diagnosticó inicialmente tumor periampular. Fue reevaluado y se le realizaron varias pruebas diagnósticas, hasta llegar al diagnóstico de Síndrome de Mirizzi, corroborado en el acto quirúrgico. El SM es una enfermedad rara de la vía biliar cuyo tratamiento es quirúrgico. La vía laparoscópica para la realización de la colecistectomía es la de elección para casos grado I y en casos seleccionados grado II. La colecistectomía y derivación bilioentérica (hepaticoyeyunostomía) conforman el tratamiento para el resto de los casos.</p

Most Common Adverse Reactions in Local Anesthetics

Los anestésicos locales son ampliamente usados en la práctica clínica en diferentes escenarios, de tal manera que el impacto de los fármacos anestésicos localizados actualmente corresponde a dos tipos: amidas y ésteres. El efecto de dichos fármacos se produce a través de su interacción con canales de sodio dependiente del voltaje, lo que previene la generación y propagación de potenciales de acción en los axones. Por consiguiente se ha realizado una búsqueda bibliográfica de artículos científicos en español e inglés, de diferentes casos donde se evidencia las reacciones adversas que estos anestésicos pueden llegar a ocasionar. Por lo tanto es fundamental saber que al momento de elegir un anestésico local, se debe administrar adecuadamente el medicamento, teniendo en cuenta aspectos como dosis y velocidad de administración, los cuales son factores esenciales para reducir el riesgo de eventos adversos.Local anesthetics are widely used in clinical practice in different scenarios, such that the impact of localized anesthetic drugs currently corresponds to two types: amides and esters. The effect of these drugs occurs through their interaction with voltage-dependent sodium channels, which prevents the generation and propagation of action potentials in the axons. Consequently, a bibliographic search of scientific articles in Spanish and English has been carried out, of different cases where the adverse reactions that these anesthetics can cause are evident. Therefore, it is essential to know that when choosing a local anesthetic, the medication must be administered appropriately, taking into account aspects such as dose and speed of administration, which are essential factors to reduce the risk of adverse events

Healthcare workers hospitalized due to COVID-19 have no higher risk of death than general population. Data from the Spanish SEMI-COVID-19 Registry

Aim To determine whether healthcare workers (HCW) hospitalized in Spain due to COVID-19 have a worse prognosis than non-healthcare workers (NHCW). Methods Observational cohort study based on the SEMI-COVID-19 Registry, a nationwide registry that collects sociodemographic, clinical, laboratory, and treatment data on patients hospitalised with COVID-19 in Spain. Patients aged 20-65 years were selected. A multivariate logistic regression model was performed to identify factors associated with mortality. Results As of 22 May 2020, 4393 patients were included, of whom 419 (9.5%) were HCW. Median (interquartile range) age of HCW was 52 (15) years and 62.4% were women. Prevalence of comorbidities and severe radiological findings upon admission were less frequent in HCW. There were no difference in need of respiratory support and admission to intensive care unit, but occurrence of sepsis and in-hospital mortality was lower in HCW (1.7% vs. 3.9%; p = 0.024 and 0.7% vs. 4.8%; p<0.001 respectively). Age, male sex and comorbidity, were independently associated with higher in-hospital mortality and healthcare working with lower mortality (OR 0.211, 95%CI 0.067-0.667, p = 0.008). 30-days survival was higher in HCW (0.968 vs. 0.851 p<0.001). Conclusions Hospitalized COVID-19 HCW had fewer comorbidities and a better prognosis than NHCW. Our results suggest that professional exposure to COVID-19 in HCW does not carry more clinical severity nor mortality

Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study

Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak. Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study. Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM. Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide

TRY plant trait database – enhanced coverage and open access

Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives
