ABSTRACT

En la educación superior, pocos estudios relacionan factores contextuales en la clase, como el énfasis del profesor en la utilidad del contenido y las características motivacionales de los estudiantes. El objetivo fue probar un modelo multinivel sobre la relación entre el énfasis del docente en la utilidad del contenido durante la clase, la autonomía de los estudiantes y, a su vez, la motivación para aprender. Participaron 3033 estudiantes universitarios matriculados de 1º a 4º grado de Ciencias de la Actividad Física y del Deporte, de universidades de España (N = 602), Portugal (N = 469), México (N = 1177), Chile (N = 372), y Brasil (N = 413). Se realizó un modelo de ecuaciones estructurales multinivel, en el que los participantes respondieron preguntas sobre el énfasis del profesor en la utilidad del contenido de la clase, la autonomía y la motivación para aprender. Se hipotetizó que el énfasis del profesor en la utilidad del contenido predecía la autonomía del estudiante que, por su vez, predecía la motivación para aprender. Los resultados, a nivel grupal e individual, indican que el énfasis del docente en la utilidad del contenido predijo la autonomía del estudiante, y la autonomía predijo la motivación para aprender.(AU)


Teacher autonomy support is related to improved student learn-ing. In higher education, few studies relate classroom contextual factors, such as teacher emphasis on content usefulness, and students' motivational characteristics. The aim was to test a multilevel model about the relation between the extent of teachers’ emphasis on the usefulness of class con-tent with student autonomy, and, in turn, on motivation to learn. The par-ticipants were 3033 university students enrolled from 1st to 4th grade of Sciences of the Physical Activity and Sport, from universities in Spain (N = 602), Portugal (N = 469), Mexico (N = 1177), Chile (N = 372), and Brazil (N = 413). A multilevel structural equation model was performed, in which participants answered questions about the teacher's emphasis on the use-fulness of class content, basic psychological need for autonomy, and moti-vation to learn. At the group and individual levels, the hypothesis is that the teacher's emphasis on the usefulness of class content predict the stu-dent autonomy, in turn, student autonomy predicts student motivation to learn. Results found at the group level and at the individual level the strength of teacher emphasis on class content predicted student autonomy; student autonomy predicted student motivation to learn.(AU)

ABSTRACT

Mental well-being is conditioned by several factors, including religious involvement and diet. However, this evidence does not exist among members of the Seventh-day Adventist Church (SDA) in Latin America, particularly Peru. This study evaluated the association between religious involvement and vegetarian diet with mental well-being in members of the SDA Church in Peru. In this cross-sectional study, the sample included 767 participants, aged 18 to 59 years. A face-to-face and online survey was administered that included information on the dietary regimen and sociodemographic characteristics. Religious involvement and mental well-being were measured using the 12-item version of the General Health Questionnaire (GHQ-12) and the Duke University Religion Index (DUREL), respectively. A multivariate analysis was conducted to investigate the factors associated with mental well-being. Being female (ß = 1.80, p < 0.001), coming from the highland region (ß = 1.98, p < 0.001), having a basic educational degree (ß = 1.85, p < 0.001), a higher level of religious involvement (ß = 0.34, p < 0.001), and being vegetarian (ß = 1.21, p < 0.001) were associated with greater mental well-being. This evidence highlights the implication of religious participation and a vegetarian diet in mental health, not only among SDA church members but also in a broader context. However, it should be recognized that direct transfer of church-based health promotion interventions and strategies to the general population can present challenges; therefore, it is suggested that these strategies should be adapted and adjusted to consider differences in the community context.

ABSTRACT

The increase in the popularity and use of electronic cigarettes (e-cigarettes) has consistently risen worldwide and has become associated with adverse health outcomes. This study has identified the attitudes and perceptions of undergraduate students who vape in three universities in Mexico. A cross-sectional study involving 495 participants was conducted using a survey from October to December 2023. Three universities in different states in Mexico collaborated with colleges in Yucatan, Durango, and Nuevo Leon, Mexico. Descriptive statistics include frequencies and percentages, and four logistic regression models were employed. In the sample, 31% and 17.54% of participants reported smoking and vaping, respectively. Students who reported vaping in the last month reported that their first experience with vaping was at an average of 17.3 years of age, and of those, 71.26% (n = 62) reported having vaped for over 100 days, while the remaining 38% reported vaping for between 2 and 100 days. Students from Veracruz and Yucatan began vaping at a younger age than in the central and northern regions. There is a need to educate students about the dangers of the chemicals in the liquids they use, the secondary exposure vapers, and the health dangers they pose.

ABSTRACT

Many natural products have been acquired from plants for their helpful properties. Medicinal plants are used for treating a variety of pathologies or symptoms. The axes of many pathological processes are inflammation, oxidative stress, and senescence. This work is focused on identifying Mexican medicinal plants with potential anti-oxidant, anti-inflammatory, anti-aging, and anti-senescence effects through network analysis and chemoinformatic screening of their phytochemicals. We used computational methods to analyze drug-like phytochemicals in Mexican medicinal plants, multi-target compounds, and signaling pathways related to anti-oxidant, anti-inflammatory, anti-aging, and anti-senescence mechanisms. A total of 1373 phytochemicals are found in 1025 Mexican medicinal plants, and 148 compounds showed no harmful functionalities. These compounds displayed comparable structures with reference molecules. Based on their capacity to interact with pharmacological targets, three clusters of Mexican medicinal plants have been established. Curatella americana, Ximenia americana, Malvastrum coromandelianum, and Manilkara zapota all have anti-oxidant, anti-inflammatory, anti-aging, and anti-senescence effects. Plumeria rubra, Lonchocarpus yucatanensis, and Salvia polystachya contained phytochemicals with anti-oxidant, anti-inflammatory, anti-aging, and anti-senescence reported activity. Lonchocarpus guatemalensis, Vallesia glabra, Erythrina oaxacana, and Erythrina sousae have drug-like phytochemicals with potential anti-oxidant, anti-inflammatory, anti-aging, and anti-senescence effects. Between the drug-like phytochemicals, lonchocarpin, vallesine, and erysotrine exhibit potential anti-oxidant, anti-inflammatory, anti-aging, and anti-senescence effects. For the first time, we conducted an initial virtual screening of selected Mexican medicinal plants, which was subsequently confirmed in vivo, evaluating the anti-inflammatory activity of Lonchocarpus guatemalensis Benth in mice.

ABSTRACT

This qualitative study aims to explore how the COVID-19 pandemic impacted healthcare access for patients with chronic conditions in Ecuador from the patient's perspective. We interviewed 19 patients diagnosed with arterial hypertension or type 2 diabetes in rural and urban areas of Ecuador during August and September 2020. We used the Framework Method to analyse the interview transcripts with ATLAS.Ti 8.4 and organised the ideas discussed using categories from the World Health Organization Commission on the Social Determinants of Health conceptual framework. Reorganization of health services during the pandemic meant that patients with arterial hypertension or diabetes could no longer attend face-to-face appointments for disease follow-up. System failures related to medication supply led to increased out-of-pocket payments, which, together with reduced or absent earnings, and in a context with limited social protection policies, meant that patients frequently went for prolonged periods without medication. Rural health initiatives, support from family and use of traditional medicine were reported as ways to manage their chronic condition during this time. Barriers to disease management disproportionately affected individuals with low socioeconomic positions. Stock shortages, lack of protective labour policies and limited reach of anticipatory policies for health emergencies likely worsened pre-existing health inequities in Ecuador.

ABSTRACT

BACKGROUND: Non-communicable diseases and psychiatric pathologies are the health problems that most affect the population in the United States. OBJECTIVE: This study aimed to examine the mediating role of patient-centered communication (PCC) in the relationship between satisfaction with medical care, physical health, and emotional well-being in American men. METHODS: A cross-sectional - predictive study was carried out. The variables analyzed were satisfaction with medical care, physical health, and emotional well-being. Information from the Health Information National Trends Survey Data (HINTS) was used; HINTS 5, cycle 3 (collected between January and June 2019) and 4 (2020). Data from 3338 men were considered (mean age: M = 55.40, SD = 19.53). Data analyses were carried out using structural equation modeling (SEM) to represent the statistical mediation model with latent and observable variables. RESULTS: Analyses showed that the variables were significantly related (P < .01). In the mediation model, there is evidence that satisfaction predicts communication (ß = .764, P < .001) and this, in turn, is related to physical health (ß = .079, P = .007) and emotional well-being (ß = .145, P < .001). In addition, the standardized estimates of the structural multiple mediation model presented acceptable goodness-of-fit indices: χ2/gl = 2.24, CFI = 0.999, TLI = 0.999, RMSEA = 0.019 [90% CI: 0.013-0.022], SRMR = 0.018. CONCLUSION: Patient-centered communication plays a significant dual mediating role in the relationship between satisfaction with medical care, physical health, and emotional well-being, respectively. Therefore, PCC is essential in healthcare for American men.

ABSTRACT

Different international organizations have spoken out in favor of the value of physical activity in the integral development of children and adolescents, which is why different guidelines have been established for governments to facilitate quality Physical Education. In this sense, the objective of this study was to analyze the factors that influence the performance of PE teachers, from the perspective of pedagogical technical advisors and school district supervisors from various school zones from the State of Chihuahua. This was a transversal study, with a qualitative approach and phenomenological focus, which was chosen because it allows the understanding of these aspects from a unique and unrepeatable process; data collection was carried out through focus groups in which PE ATP supervisors participated and data were collaboratively analyzed. The main results indicated that Physical Education does not have the same importance as other subjects, a situation that is reflected in: constant curricular reforms, administrative inconsistencies, dependence on the school organization, and being seldom taken into account in decision-making. It was concluded that strict public policies are required to be applied uniformly throughout the country, as well as privilege Physical Education within the Basic Education curriculum in Mexico.

ABSTRACT

Anxiety about aging is an important mediating factor in attitudes and behavior toward elderly individuals as well as a mediating factor in the adjustment to one's own aging processes. The aim of this study was to analyze the factor structure, internal consistency and factorial invariance by sex of the Lasher and Faulkender Anxiety about Aging Scale. The sample consisted of 601 Mexican older adults, 394 women and 207 men, with a mean age of 70.69 ± 8.10 years. The factor structure of the questionnaire was analyzed using confirmatory factor analysis. Analyses show that a four-factor structure is feasible and adequate. The four-factor structure (fear of the elderly, psychological concerns, physical appearance and fear of loss), according to statistical and substantive criteria, showed adequate reliability and validity indicators. However, the obtained model does not fully coincide with that proposed by the questionnaire authors, although it continues to support the multi-factor component of anxiety about aging. On the other hand, the factor structure, the factor loadings and the intercepts are considered invariant in the two populations (men and women); however, there are differences between populations on the means of the physical appearance and fear of loss factors.

ABSTRACT

RESUMEN Los microorganismos son de gran interés porque colonizan todo tipo de ambiente, sin embargo, uno de los problemas al que nos enfrentamos para conocer su diversidad biológica es que no todos los microorganismos son cultivables. El desarrollo de nuevas tecnologías como la generación de vectores de clonación aunado al desarrollo de técnicas de secuenciación de alto rendimiento ha favorecido el surgimiento de una nueva herramienta llamada metagenómica, la cual nos permite estudiar genomas de comunidades enteras de microorganismos. Debido a que ningún ambiente es idéntico a otro, es importante mencionar que dependiendo del tipo de muestra a analizar será el tipo de reto al cual nos enfrentaremos al trabajar con metagenómica, en el caso específico del suelo existen diversas variantes como la contaminación del suelo con metales pesados o diversos compuestos químicos que podrían limitar los estudios. Sin embargo, pese a las limitaciones que el mismo ambiente presenta, la metagenómica ha permitido tanto el descubrimiento de nuevos genes como la caracterización de las comunidades microbianas que influyen positivamente en el desarrollo de plantas, lo cual en un futuro podría generar un gran impacto en la agricultura. En este artículo se realizó una revisión de diversas investigaciones que han empleado metagenómica, reportadas en las bases de datos de PudMed y Google Schoolar, con el objetivo de examinar los beneficios y limitaciones de las diversas metodologías empleadas en el tratamiento del ADN metagenómico de suelo y el impacto de la metagenómica en la agricultura.


ABSTRACT Microorganisms are of great interest because they colonize all types of environment, however, one of the problems we face in knowing biological diversity is that not all microorganisms are cultivable. The development of new technologies such as the generation of cloning vectors coupled with the development of high performance sequencing techniques, have favored the emergence of a new tool in science called metagenomics, which allows us to study genomes of entire communities. Since all environments are different, the type of challenge that we will face when working with metagenomics is going to change depending of the type of sample, in the specific case of soils, there are several variables, such as soil contamination with heavy metals or chemical compounds that could limit metagenomic studies. However, despite the limitations that the environment presents, with the help of metagenomics, both gene discovery and the characterization of microbial communities that positively influence plant development have been achieved, which could generate a greater impact on agriculture in the future. In this article a review of several investigations that have used metagenomics, reported in the PudMed and Google Schoolar databases was carried out, with the aim of examining the benefits and limitations of the various methodologies used in the treatment of metagenomic DNA from soil and the impact of metagenomics in agriculture.

ABSTRACT

In the study of the chemical communication of adults of the Melolonthidae family, bacteria have been observed in the epithelium of the genital chamber; possibly, bacteria are involved in the production of sex attractants in their hosts. Therefore, it is important to identify the volatile organic compounds from bacteria (VOCsB) released by these microorganisms and study the biological activity stimulated by VOBCs in adults of Melolonthidae. In this study, bacteria were isolated from the genital chamber of Cyclocephala lunulata and Cyclocephala barrerai, from which VOCsB were extracted using static headspace solid-phase microextraction (SHS-SPME) and dynamic headspace Super Q solid-phase extraction (DHS-SPE) and analyzed using gas chromatography-mass spectrometry. The effect of VOCsB on the hosts and conspecifics was evaluated utilizing an olfactometer and electroantennography (EAG). Two species of Enterobacteria were isolated from the genital chamber of each female species, and VOCsB derived from sulfur-containing compounds, alcohols, esters, and fatty acids were identified. An attraction response was observed in olfactometry studies, and antennal responses to VOCsB were confirmed in EAG bioassays. With these results, new perspectives on the relationship between these beetles and their bacteria emerge, in addition to establishing a basis for management programs in the future.

ABSTRACT

El presente estudio analiza las propiedades psicométricas propuestos por Rodríguez-Villalobos, Viciana, Tristán y Blanco (2017) para el Autoinforme de Barreras para la Práctica de Ejercicio Físico (ABPEF-M) en hombres y mujeres deportistas universitarios. La muestra total fue de 413 universitarios mexicanos deportistas 174 mujeres y 239 hombres, con edades comprendidas entre 18-26 años (M = 20.76; DE = 2.06). La estructura factorial del cuestionario se analizó mediante análisis factoriales confirmatorios. Los análisis, muestran que una estructura tetrafactorial (imagen corporal, fatiga, obligaciones y ambiente) es viable y adecuada tanto para la muestra total como para las poblaciones de hombres y mujeres. La estructura de cuatro factores, atendiendo a criterios estadísticos y sustantivos, ha mostrado adecuados indicadores de ajuste de fiabilidad y validez. Además, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes de acuerdo al género; sin embargo, no se encontraron diferencias entre hombres y mujeres deportistas en cuanto su percepción sobre la presencia de barreras en las cuatro dimensiones estudiadas


The aim of this research was to analyze the psychometric properties proposed by Rodríguez-Villalobos et al. (2017) for the Barriers for the Practice of Physical Activity Scale (ABPEF-M) in university athletes mens and women. The total sample has been composed by 413 Mexican university athletes, 174 women and 239 mens, with ages from 18-26 years (M = 20.76, SD = 2.06). The factor structure of questionnaire has been analized through the confirmatory factor analysis. This analysis shows that a tetrafactorial structure (body image, fatigue, obligations, and environment) is viable and adequate for the total sample and the populations of mens and woman. The four factors structure, according to statistical and substantive criteria, has shown adequate indicators of reliability and validity adjustment. On the other hand, the factorial structure, the factorial loads and the intercepts are considered invariant according to the variable gender; however, no differences were found between mens and women athletes in their perception of the presence of barriers in the four dimensions studied

ABSTRACT

BACKGROUND: Identifying lifestyle-related health predictors affecting adolescent behaviors is a matter of interest and study for diverse audiences, including the religious sphere. The Adventist religion recommends their followers to adopt a healthy diet, adequate rest, physical activity, sufficient water intake, and non-use of addictive substances such as alcohol, tobacco, and drugs, as well as fostering faith and hope to give meaning to life. METHODS: A cross-sectional and observational study was conducted among adolescent students aged 13 to 19 years old in Montemorelos City, Nuevo León, Northern Mexico, between September 14, 2017 and February 13, 2018. This study included 363 Mexican adolescents, consisting of 202 Adventists and 161 non-Adventists. The binomial logistic regression analysis was performed to examine the relationships between religious affiliation and life-style behaviors and evaluate the effect of life-style behaviors on health outcomes by religious affiliation. Age, gender, type of residence, and place of birth were controlled. RESULTS: We found that Adventist adolescents were more likely to be watching TV for 2 h or less per day (p < 0.001), have enough sleeping time for 7 h or more (p < 0.001), go to bed early at 11 o'clock or before (p < 0.001), and have breakfast (p = 0.006) than non-Adventist adolescents significantly. It indicates that Adventist students are more likely to have healthier life-style behaviors than non-Adventist students. The multiple binomial regression models showed that in the group of Adventist adolescents sporting activity and hours watching TV were significantly associated with obesity risk (p = 0.001) and risky eating patterns (p = 0.044), respectively, controlling for age, gender, type of residence, and place of birth. No relationship was found between life-style behaviors and health outcomes in non-Adventist adolescents. CONCLUSIONS: Religious affiliation could serve as a predictor of healthy behaviors among adolescents. This study concluded that Adventist adolescents are more likely to have a healthier lifestyle behavior than non-Adventist adolescents and various health-related behaviors were specifically identified among Adventist participants.

ABSTRACT

Portions of northern Mexico are experiencing a re-emergence of Rocky Mountain spotted fever (RMSF), a tickborne disease caused by Rickettsia rickettsii, a member of the spotted fever group of rickettsiae (SFGR). Infection with R. rickettsii can result in serious and life-threatening illness in people and dogs. Canine seroprevalence has been used as a sentinel for human RMSF in previous studies. This study aims to quantify SFGR seroprevalence in canines in three northern Mexican states and identify risk factors associated with seropositivity. A total of 1,136 serum samples and 942 ticks were obtained from dogs participating in government sterilization campaigns and from animal control facilities in 14 Mexican cities in three states. SFGR antibodies were detected using indirect immunofluorescence antibody assays at titre values ≥1/64. Six per cent (69 dogs) showed antibodies to SFGR, with the highest seroprevalence reported in Baja California (12%), Coahuila (4%) and Sonora (4%). Dogs from Baja California had three times higher odds of having SFGR antibodies compared to dogs from Sonora (OR = 3.38, 95% CI, 1.81-6.37). Roughly one quarter (25%) of surveyed dogs were parasitized by ticks (Rhipicephalus sanguineus sensu lato) at the time of sample collection. A portion of collected ticks were tested for rickettsial DNA using polymerase chain reaction. Positive samples were then sequenced, showing evidence of SFGR including R. massiliae, R. parkeri and R. rickettsii. Dogs that spent the majority of time on the street, such as free-roaming or community-owned dogs, showed a greater risk of tick infestation, seropositivity, bearing seropositive ticks, and may play a pivotal role in the spread of SFGR among communities. Estimating the seroprevalence of SFGR in the canine population can help public health campaigns target high-risk communities for interventions to reduce human RMSF cases.

ABSTRACT

Successful delivery of the United Nations sustainable development goals and implementation of the Paris Agreement requires technologies that utilize a wide range of minerals in vast quantities. Metal recycling and technological change will contribute to sustaining supply, but mining must continue and grow for the foreseeable future to ensure that such minerals remain available to industry. New links are needed between existing institutional frameworks to oversee responsible sourcing of minerals, trajectories for mineral exploration, environmental practices, and consumer awareness of the effects of consumption. Here we present, through analysis of a comprehensive set of data and demand forecasts, an interdisciplinary perspective on how best to ensure ecologically viable continuity of global mineral supply over the coming decades.

ABSTRACT

Esta investigación, mediante modelos de ecuaciones estructurales, analiza los efectos directos e indirectos del género y el cuidado de la salud sobre el autoconcepto físico. La muestra total fue de 938 universitarios mexicanos, con una edad media de 20.46 años (DE=1.83). Los resultados indican que el género y los hábitos saludables son las variables con mayor poder explicativo sobre la competencia motora y el atractivo físico. También destaca la capacidad mediadora del estrés entre los hábitos no saludables y el autoconcepto físico. Futuras investigaciones deberían replicar estos hallazgos en muestras más amplias (AU)

ABSTRACT

El presente estudio pretendió replicar los resultados psicométricos propuestos por Botella, Ribas y Ruiz para la versión española del Multidimensional Body Self Relations Questionnaire en una muestra de universitarios mexicanos. Participaron un total de 1539 universitarios con una edad media de 20.56 años (DE=1.88). La estructura del cuestionario se analizó a través de análisis factoriales exploratorios y confirmatorios. Los resultados mostraron que una estructura de dos factores (importancia subjetiva de la apariencia física e importancia subjetiva de la forma física) es viable y adecuada. Esta estructura atendió a criterios estadísticos y sustantivos, mostrando adecuados indicadores de ajuste de fiabilidad y validez. Sin embargo, el modelo obtenido no coincide con el planteado por Botellay colaboradores. Futuras investigaciones deberían replicar estos hallazgos en muestras más amplias (AU)


The aim of this study was to analyze if psychometric results proposed by Botella, Ribas and Ruiz for the Spanish version of the Multidimensional Body Self Relations Questionnaire could be replicated in Mexican university students. A total of 1539 university students participated in this study with a mean age of 20.56 years (SD = 1.88). The factor structure of the questionnaire was analyzed trough exploratory and confirmatory factor analyses. Results showed a feasible and adequate structure of two factors (subjective importance of the physical appearance and subjective importance of the physical shape), with adequate fit indices of reliability and validity, according to statistical and substantive criteria. However, the obtained model does not coincide with that proposed by Botella et al. Future research should replicate these findings in wider samples (AU)

Porém, o modelo obtendo no coincide com o apresentado por Botella et al. Futuras investigações deveriam replicar estos achados em amostras mais grandes (AU)

ABSTRACT

BACKGROUND: Quality of life (QoL) is an important outcome in the treatment of schizophrenia. Cognitive deficits have an impact on functional outcomes. Cognitive remediation therapy is emerging as a psychological intervention that targets cognitive impairment, but the effect of computer-assisted cognitive remediation on neuropsychology and social functioning and wellbeing remains unclear. The aim of the current study is to investigate the neurocognitive outcomes of computer-assisted cognitive remediation (CACR) therapy in a sample of schizophrenia patients, and to measure the quality of life and self-esteem as secondary outcomes. METHODS: Sixty-seven people with schizophrenia were randomly assigned to computer-assisted cognitive remediation or an active control condition. The main outcomes were neuropsychological measures and secondary outcomes (self-esteem and quality of life). Measurements were recorded at baseline and post-treatment. RESULTS: The CACR therapy group improved in speed of processing, working memory and reasoning and problem-solving cognitive domains. QoL and self-esteem measures also showed significant improvements over time in this group. CONCLUSIONS: Computer-assisted cognitive remediation therapy for people with schizophrenia achieved improvements in neuropsychological performance and in QoL and self-esteem measurements.

ABSTRACT

Las causas más frecuentes de síndrome nefrótico en niños son la nefropatía de cambios mínimos y la glomeruloesclerosis focal y segmentaria; las formas secundarias son poco frecuentes. Se presenta el caso de un niño de 5 años y 7 meses de edad, con síndrome nefrótico resistente a corticoides, en quién la biopsia renal mostró nefropatía membranosa con cambios citopáticos focales en las células tubulares, compatibles con citomegalovirus. La inmunofluorescencia mostró depósitos de IgM y C3 en el mesangio. La proteinuria remitió con la terapia con ganciclovir intravenoso, valganciclovir vía oral y ciclofosfamida vía oral.


The most frequent causes of nephrotic syndrome in children are minimal change glomerulopathy and focalsegmental glomeruloesclerosis, secondary forms are less frequent. We present the case of 5-year and 7-month boy with nephrotic syndrome resistant to steroids in whom the renal biopsy showed membranous glomerulonephritis with focal cythopatic changes in the tubular cells compatible with cytomegalovirus infection. Immunofluorescence showed mesangial deposits of IgM and C3. Proteinuria remitted with intravenous gancyclovir therapy followed by oral valgancyclovir and cyclophosphamide.

ABSTRACT

Con el objetivo de rediseñar el sistema de evaluación de la asignatura Introducción al Laboratorio Clínico se realizó un análisis de la categoría evaluación, privilegiando enfoques cualitativo y holista; se destaca además su función formativa esencial y abarcadora con respecto al resto de ellas, cómo utilizarla y qué beneficios reportaría su aplicación a la formación laboral de los estudiantes de Laboratorio Clínico. Luego de analizar la forma actual de evaluar, se determinó incluir actividades de la práctica laboral investigativa. Se concluye que este proceso es una cuestión nuclear y categórica en las actividades de enseñanza-aprendizaje. Del modelo de evaluación aplicado depende en gran medida el resto de los planteamientos de la actividad docente y de los alumnos. Los cambios en el proceso de evaluación tienen que ser parte de un programa de innovación; abarcan currículo, didáctica y evaluación; tres elementos que, junto a los contenidos de aprendizaje están estructural y funcionalmente relacionados(AU)
