RESUMO
Music is powerful in conveying emotions and triggering affective brain mechanisms. Affective brain responses in previous studies were however rather inconsistent, potentially because of the non-adaptive nature of recorded music used so far. Live music instead can be dynamic and adaptive and is often modulated in response to audience feedback to maximize emotional responses in listeners. Here, we introduce a setup for studying emotional responses to live music in a closed-loop neurofeedback setup. This setup linked live performances by musicians to neural processing in listeners, with listeners' amygdala activity was displayed to musicians in real time. Brain activity was measured using functional MRI, and especially amygdala activity was quantified in real time for the neurofeedback signal. Live pleasant and unpleasant piano music performed in response to amygdala neurofeedback from listeners was acoustically very different from comparable recorded music and elicited significantly higher and more consistent amygdala activity. Higher activity was also found in a broader neural network for emotion processing during live compared to recorded music. This finding included observations of the predominance for aversive coding in the ventral striatum while listening to unpleasant music, and involvement of the thalamic pulvinar nucleus, presumably for regulating attentional and cortical flow mechanisms. Live music also stimulated a dense functional neural network with the amygdala as a central node influencing other brain systems. Finally, only live music showed a strong and positive coupling between features of the musical performance and brain activity in listeners pointing to real-time and dynamic entrainment processes.

Phenylketonuria (PKU) is a genetic disorder caused by variations in the phenylalanine hydroxylase (PAH) gene. Among the 3369 reported PAH variants, 33.7% are missense alterations. Unfortunately, 30% of these missense variants are classified as variants of unknown significance (VUS), posing challenges for genetic risk assessment. In our study, we focused on analyzing 836 missense PAH variants following the American College of Medical Genetics and Genomics/Association for Molecular Pathology (ACMG/AMP) guidelines specified by ClinGen PAH Variant Curation Expert Panel (VCEP) criteria. We utilized and compared variant annotator tools like Franklin and Varsome, conducted 3D structural analysis of PAH, and examined active and regulatory site hotspots. In addition, we assessed potential splicing effect of apparent missense variants. By evaluating phenotype data from 22962 PKU patients, our aim was to reassess the pathogenicity of missense variants. Our comprehensive approach successfully reclassified 309 VUSs out of 836 missense variants as likely pathogenic or pathogenic (37%), upgraded 370 likely pathogenic variants to pathogenic, and reclassified one previously considered likely benign variant as likely pathogenic. Phenotypic information was available for 636 missense variants, with 441 undergoing 3D structural analysis and active site hotspot identification for 180 variants. After our analysis, only 6% of missense variants were classified as VUSs, and three of them (c.23A>C/p.Asn8Thr, c.59_60delinsCC/p.Gln20Pro, and c.278A >T/p.Asn93Ile) may be influenced by abnormal splicing. Moreover, a pathogenic variant (c.168G>T/p.Glu56Asp) was identified to have a risk exceeding 98% for modifications of the consensus splice site, with high scores indicating a donor loss of 0.94. The integration of ACMG/AMP guidelines with in silico structural analysis and phenotypic data significantly reduced the number of missense VUSs, providing a strong basis for genetic counseling and emphasizing the importance of metabolic phenotype information in variant curation. This study also sheds light on the current landscape of PAH variants.

In order to know whether there is a risk of anisakiasis (or anisakidosis) by consumption of fish of the genus Mullus from the western Mediterranean Sea, which are appreciated for their quality, an epidemiological survey was carried out to evaluate the occurrence of zoonotic or potentially zoonotic nematodes in M. barbatus and M. surmuletus. Although the presence of the third larval stage (L3) of anisakids (Anisakis and Contracaecum) has been previously described in these fish, the results showed the absence of anisakids and the presence, never in muscle, of L3 and L4 of raphidascaridids of the genus Hysterothylacium, molecularly identified as H. fabri. Phylogenetic analysis groups them into the Mediterranean Sea clade, far from individuals isolated in the Pacific Ocean. Prevalence was slightly higher, but not significant, in M. barbatus versus M. surmuletus (72.3% vs 60.0%), but mean intensity (MI) and mean abundance (MA) parameters were approximately twice as high in M. barbatus as in M. surmuletus (MI 5.8 vs 2.8, p = .001; MA 4.2 vs 1.7, p < .001). The presence of the parasite seems to have different effects on these two sympatric species. In M. barbatus it seems to affect their growth, as it appreciably reduces the value of allometry coefficient in infected fish (2.78 vs. 2.18). On the other hand, in M. surmuletus the infection significantly (p < .04) affects the Fulton's condition factor, an indicator of the health status of the fish. It can be concluded that the ingestion of these fish by the people poses negligible risk of anisakiasis, but the consumer should continue to be urged to follow the rules of prevention against this illness.
RESUMO
AIM: Adolescents born very preterm (VPT; <32 weeks of gestation) face an elevated risk of executive, behavioral, and socioemotional difficulties. Evidence suggests beneficial effects of mindfulness-based intervention (MBI) on these abilities. This study seeks to investigate the association between the effects of MBI on executive, behavioral, and socioemotional functioning and reliable changes in large-scale brain networks dynamics during rest in VPT young adolescents who completed an 8-week MBI program. METHODS: Neurobehavioral assessments and resting-state functional magnetic resonance imaging were performed before and after MBI in 32 VPT young adolescents. Neurobehavioral abilities in VPT participants were compared with full-term controls. In the VPT group, dynamic functional connectivity was extracted by using the innovation-driven coactivation patterns framework. The reliable change index was used to quantify change after MBI. A multivariate data-driven approach was used to explore associations between MBI-related changes on neurobehavioral measures and temporal brain dynamics. RESULTS: Compared with term-born controls, VPT adolescents showed reduced executive and socioemotional functioning before MBI. After MBI, a significant improvement was observed for all measures that were previously reduced in the VPT group. The increase in executive functioning, only, was associated with reliable changes in the duration of activation of large-scale brain networks, including frontolimbic, amygdala-hippocampus, dorsolateral prefrontal, and visual networks. CONCLUSION: The improvement in executive functioning after an MBI was associated with reliable changes in large-scale brain network dynamics during rest. These changes encompassed frontolimbic, amygdala-hippocampus, dorsolateral prefrontal, and visual networks that are related to different executive processes including self-regulation, attentional control, and attentional awareness of relevant sensory stimuli.

Social workers have a greater than average risk of suffering burnout syndrome. In the same way as the professionals, students too can suffer academic burnout. However, few empirical studies have studied burnout and protective factors in social work students exclusively. Emotional intelligence (EI) has been described as a protective factor for burnout both in the professional and the academic context. The present study aims to explore which components of EI predict the burnout domains in students studying a degree in social work, in Spain. To this end, 87 social work students completed a questionnaire in which information was gathered on EI, burnout, average grade in the degree, and sociodemographic variables. The regression analysis results indicate that the students with poorer academic success and from higher years reported greater symptoms of burnout. Regarding the components of EI, emotional clarity and emotional repair predict the academic efficacy perceived by the students. These results highlight the importance of including EI in academic policies to promote the design of EI training programs aimed at developing EI skills, particularly emotional clarity and emotional repair, as a way of improving the perception of efficacy in social work students.
RESUMO
Currently, robust evidence is lacking to support one exercise type over another in the prevention of physical and cognitive decline and falls among older adults, primarily because of the lack of comparative trials of proven interventions. Therefore, a 12-month randomized, single-blind, comparative effectiveness trial is conducted, in which 142 older adults at high risk for falls are randomized (1:1) to receive an evidence-based Dalcroze Eurhythmics (DE) exercise program (once weekly, group-based) or an evidence-based multicomponent (MULTI) exercise program incorporating balance, functional, and strength training activities (twice weekly, group- and home-based), for 12 months. The primary outcome is gait variability under dual-task at 12 months. At 12 months, the DE group has significant improvements compared with MULTI group on gait under both dual-task (adjusted ß for stride variability: -2.3, 95%CI, -3.1 to -1.4; p < 0.001) and single-task, and on a variety of secondary physical and cognitive/executive function outcomes. The adjusted hazard ratio for falls is 0.58 (95%CI, 0.37 to 0.93) for the DE group compared with MULTI group. In conclusion, DE exercise is more effective than MULTI exercise in improving physical and cognitive function and reducing falls in older adults. The mechanisms underlying DE exercise-induced benefits remain to be fully elucidated.
RESUMO
Purpose: The main aim of our study was to explore the utility of artificial intelligence (AI) in diagnosing autism spectrum disorder (ASD). The study primarily focused on using machine learning (ML) and deep learning (DL) models to detect ASD potential cases by analyzing text inputs, especially from social media platforms like Twitter. This is to overcome the ongoing challenges in ASD diagnosis, such as the requirement for specialized professionals and extensive resources. Timely identification, particularly in children, is essential to provide immediate intervention and support, thereby improving the quality of life for affected individuals. Methods: We employed natural language processing (NLP) techniques along with ML models like decision trees, extreme gradient boosting (XGB), k-nearest neighbors algorithm (KNN), and DL models such as recurrent neural networks (RNN), long short-term memory (LSTM), bidirectional long short-term memory (Bi-LSTM), bidirectional encoder representations from transformers (BERT and BERTweet). We extracted a dataset of 404,627 tweets from Twitter users using the platform's API and classified them based on whether they were written by individuals claiming to have ASD (ASD users) or by those without ASD (non-ASD users). From this dataset, we used a subset of 90,000 tweets (45,000 from each classification group) for the training and testing of these models. Results: The application of our AI models yielded promising results, with the predictive model reaching an accuracy of almost 88% when classifying texts that potentially originated from individuals with ASD. Conclusion: Our research demonstrated the potential of using AI, particularly DL models, in enhancing the accuracy of ASD detection and diagnosis. This innovative approach signifies the critical role AI can play in advancing early diagnostic techniques, enabling better patient outcomes and underlining the importance of early identification of ASD, especially in children.
RESUMO
Osteosarcoma and Ewing sarcoma are bone tumors mostly diagnosed in children, adolescents, and young adults. Despite multimodal therapy, morbidity is high and survival rates remain low, especially in the metastatic disease setting. Trials investigating targeted therapies and immunotherapies have not been groundbreaking. Better understanding of biological subgroups, the role of the tumor immune microenvironment, factors that promote metastasis, and clinical biomarkers of prognosis and drug response are required to make progress. A prerequisite to achieve desired success is a thorough, systematic, and clinically linked biological analysis of patient samples, but disease rarity and tissue processing challenges such as logistics and infrastructure have contributed to a lack of relevant samples for clinical care and research. There is a need for a Europe-wide framework to be implemented for the adequate and minimal sampling, processing, storage, and analysis of patient samples. Two international panels of scientists, clinicians, and patient and parent advocates have formed the Fight Osteosarcoma Through European Research consortium and the Euro Ewing Consortium. The consortia shared their expertise and institutional practices to formulate new guidelines. We report new reference standards for adequate and minimally required sampling (time points, diagnostic samples, and liquid biopsy tubes), handling, and biobanking to enable advanced biological studies in bone sarcoma. We describe standards for analysis and annotation to drive collaboration and data harmonization with practical, legal, and ethical considerations. This position paper provides comprehensive guidelines that should become the new standards of care that will accelerate scientific progress, promote collaboration, and improve outcomes.

Clinical translation of gene therapy has been challenging, due to limitations in current delivery vehicles such as traditional viral vectors. Herein, we report the use of gRNA:Cas9 ribonucleoprotein (RNP) complexes engineered extracellular vesicles (EVs) for in vivo gene therapy. By leveraging a novel high-throughput microfluidic droplet-based electroporation system (µDES), we achieved 10-fold enhancement of loading efficiency and more than 1000-fold increase in processing throughput on loading RNP complexes into EVs (RNP-EVs), compared with conventional bulk electroporation. The flow-through droplets serve as enormous bioreactors for offering millisecond pulsed, low-voltage electroporation in a continuous-flow and scalable manner, which minimizes the Joule heating influence and surface alteration to retain natural EV stability and integrity. In the Shaker-1 mouse model of dominant progressive hearing loss, we demonstrated the effective delivery of RNP-EVs into inner ear hair cells, with a clear reduction of Myo7ash1 mRNA expression compared to RNP-loaded lipid-like nanoparticles (RNP-LNPs), leading to significant hearing recovery measured by auditory brainstem responses (ABR).

Resumen (analítico) El artículo analiza las construcciones de juventud presentes en la Acción Católica Argentina y sus vínculos con trayectorias de jóvenes militantes insertos en parroquias del Gran Buenos Aires. Para el abordaje metodológico cualitativo se utilizan los siguientes materiales de campo, producidos entre 2016 y 2018: entrevistas en profundidad realizadas a jóvenes católicos, registros de observación participante en parroquias y eventos nacionales de Acción Católica Argentina y análisis de documentos institucionales. Dentro de la Acción Católica Argentina, se identifican tensiones entre las definiciones de juventud producidas por la institución y las trayectorias juveniles. Los jóvenes experimentan modos de «ser¼ y de «vivir¼ la juventud distintos a los propuestos por la Acción Católica Argentina, acordes con los cambios sociales y culturales que se produjeron en Argentina en las últimas décadas.
Abstract (analytical) This article analyzes the constructions of youth produced in the Acción Católica Argentina (Argentinian Catholic Action) organization and their link with the trajectories of militant youth living in parishes of Gran Buenos Aires. Field materials produced between 2016 and 2018 are analyzed using a qualitative methodological approach that consists of: in-depth interviews with Catholic youth; participant observation records from parish and national Argentinian Catholic Action events; and the analysis of institutional documents. In Argentinian Catholic Action, tensions were identified between the definitions of youth produced by the institution and young people's own trajectories. Young people experience ways of «being¼ and «living¼ that are different from those proposed by the Argentinian Catholic Action and that respond to the social and cultural changes produced in Argentine society in recent decades.

RESUMEN Introducción: Existen claras recomendaciones para el manejo lipídico en los diabéticos. Una nueva fórmula para el cálculo del C-LDL mejoraría la imprecisión de la fórmula de Friedewald. Objetivos: Analizar el uso de estatinas y el cumplimiento de las metas lipídicas en pacientes diabéticos, evaluando las consecuencias de aplicar una nueva fórmula para el cálculo del C-LDL. Métodos: Estudio descriptivo, transversal y multicéntrico. Se incluyeron diabéticos tipo 2 mayores de 18 años. El C-LDL se calculó con la fórmula clásica (Friedewald) y la nueva fórmula. Se siguieron las recomendaciones del documento de posición para el uso adecuado de estatinas (Sociedad Argentina de Cardiología). Resultados: Se incluyeron 528 pacientes. En prevención secundaria, el 77,2% recibió estatinas (23,4% alta intensidad). El 36,6% y el 36,0% alcanzaron la meta de C-LDL menor a 70 mg/dL y de C-noHDL inferior a 100 mg/dL, respectivamente. El 20,8% de los pacientes con un C-LDL menor de 70 mg/dL (Friedewald) salió de meta al aplicar la nueva fórmula. En los pacientes en prevención primaria con factores de riesgo o daño de órgano blanco, el 62,2% recibió estatinas (14,7% alta intensidad). El 20,9% y el 20,4% alcanzaron la meta de C-LDL menor a 70 mg/dL y de C-noHDL inferior a 100 mg/dL. El 27,7% de los pacientes con un C-LDL menor de 70 mg/dL (Friedewald) salió de meta al aplicar la nueva fórmula. A mayor nivel de triglicéridos, más pacientes salieron de meta de C-LDL con la nueva fórmula. Conclusión: El cumplimiento de las metas lipídicas y el uso adecuado de estatinas en esta población fue deficiente. Aplicar la nueva fórmula de C-LDL optimizó la evaluación de estos pacientes.
ABSTRACT Background: There are clear recommendations for lipid management in diabetic patients. A new formula for the calculation of LDL-cholesterol (LDL-C) would improve the inaccuracy of the Friedewald formula. Objectives: The aim of this study was to analyze the use of statins and the fulfillment of lipid goals in diabetic patients, evaluating the consequences of applying a new formula for LDL-C calculation. Methods: This was a descriptive, cross-sectional, multicenter study including type 2 diabetic patients over 18 years of age. LDL-C was calculated using the classic Friedewald formula and the new formula. Recommendations of the position document for the appropriate use of statins from the Argentine Society of Cardiology were followed. Results: A total of 528 patients were included in the study. In secondary prevention, 77.2% of patients received statins (23.4% high-intensity statins) and 36.6% and 36.0% of these patients achieved the goals of LDL-C below 70% mg/dl and non-HDL-C below 100 mg/dl, respectively. In 20.8% of patients with LDL-C below 70 mg/dl according to the Friedewald formula, this goal was not attained when the new formula was applied. In primary prevention, 62.2% patients with risk factors or white organ damage received statins (14.7% high-intensity statins) and 20.9% and 20.4% achieved the goals of LDL-C below 70% mg/dl and non-HDL-C below 100 mg/dl. In 27.7% of patients with LDL-C below 70 mg/dl using the Friedewald formula, this goal was not reached when applying the new formula. More patients did not achieve the LDL-C goal with the new formula when the triglyceride level was higher. Conclusion: In this population, the appropriate use of statins and the fulfillment of lipid goals were poor. Applying the new LDL-C formula optimized the evaluation of these patients.
RESUMO
RESUMEN En la intersección entre religión y salud, las demandas de sanación, liberación y exorcismo expresan malestares indefinidos que van desde afecciones físicas y psiquiátricas hasta problemas psicológicos y relacionales. Para comprender esta demanda creciente, este estudio se propone analizar, por un lado, las concepciones de persona y enfermedad y, por otro, las terapéuticas que los sacerdotes y sus asistentes ponen en funcionamiento, a partir de una investigación etnográfica con observación participante y entrevistas en profundidad realizadas entre 2013 y 2017 en parroquias de la ciudad de La Plata y otras localidades de la provincia de Buenos Aires. Los resultados nos permiten comprender que la concepción de persona -sobre la cual se desarrollan las terapéuticas- supone un ensanchamiento del individuo hacia los planos físico, psicológico y espiritual, y que las nociones de enfermedad y bienestar abarcan a la persona, a su entorno y a las generaciones pasadas.
ABSTRACT At the intersection of religion and health, demands for healing, liberation and exorcism express undefined discomforts that span from physical and psychiatric conditions to relational and psychological problems. To understand this growing demand in the population, this study seeks to analyze, on the one hand, the underlying conceptions of person and disease and, on the other, the therapeutics that priests and their assistants put into action, based on an ethnographic study with participant observation and in-depth interviews carried out between 2013 and 2017 in parishes in the city of La Plata and other localities of the province of Buenos Aires. The results enable us to understand that the conception of person based upon which therapeutic actions are carried out involves an expansion of the individual to the physical, psychological and spiritual planes, and that the notions of disease and wellbeing include the person, their environment and past generations.

La neurofibromatosis es el síndrome neurocutáneo más frecuente, una enfermedad hereditaria con afectación multisistémica. Se distinguen tres formas clínicas de la enfermedad; la neurofibromatosis tipo 1 (NF-1) es la más frecuente. A las lesiones cutáneas, presentes en la mayoría de los casos, se pueden asociar tumores en cualquier localización. Los neurofibromas son característicos de la NF-1. El objetivo de esta comunicación es describir una complicación poco frecuente de la NF-1 que representa un desafío terapéutico debido a la topografía y frecuencia de recidivas. Se trata de una niña de 3 años con NF-1 con síntomas de mielopatía multisegmentaria de instalación progresiva de dos meses de evolución. La imagenología evidenció una tumoración cérvico-dorsal con compresión medular. La exéresis tumoral permitió confirmar neurofibroma intradural, extramedular. Los neurofibromas plexiformes se caracterizan por su comportamiento infiltrativo y diseminación paraespinal extensa. La resección de estas lesiones genera habitualmente morbilidad asociada al compromiso de estructuras críticas extraespinales y dificulta su resección completa tal como ocurrió en el caso clínico presentado. Se destaca la importancia de realizar un correcto seguimiento clínico y eventualmente imagenológico de los pacientes con NF-1 para detectar y abordar oportunamente los tumores, su complicación más importante.
Neurofibromatosis is one of the most frequent neurocutaneous syndrome. It is an inherited diseasewhich affects multiple systems. Three clinical presentations of the disease can be distinguished being type 1 neurofibromatosis the most common. Tumors at any body location can be associated to the usually presented cutaneous lesions. Neurofibromas are characteristic of type 1 neurofibromatosis. The aim of this study is to describe a less frequent complication of the disease which represents a therapeutic challenge due to its topography and frequency of recurrences. This is the case of a 3 year-old girl with type 1 neurofibromatosis with symptoms of multisegmental myelopathy. A cervical-dorsal tumor with medullary compression was shown in medical imaging. Tumor extraction allowed to confirm intradural, extramedullary neurofibroma. Plexiform neurofibromas are characterized by their infiltrative behavior and extensive paraspinal dissemination. Resection of these lesions usually generates morbidity associated with the involvement of extra-spinal critical structures and hinders their complete resection as occurred in the presented clinical case. It is important to perform a correct clinical and eventually imaging follow-up of patients with NF-1 to detect and treat tumors, its most important complication.

A imagem mostrou um tumor cérvico-dorsal com compressão da medula espinhal. A excisão do tumor permitiu confirmar neurofibroma intradural, extramedular. Os neurofibromes plexiformes são caracterizados pelo seu comportamento infiltrativo e sua disseminação paraspinal extensa. A ressecção dessas lesões geralmente gera morbidade associada ao envolvimento de estruturas críticas extra-espinhais e dificulta sua ressecção completa, como ocorreu no caso clínico apresentado. Destaca-se a importância de realizar um acompanhamento clínico e, eventualmente, de imagens de pacientes com NF-1 para detectar e tratar oportunamente os tumores, sua complicação mais importante.

Introducción: La detección de genes asociados a virulencia en Helicobacter pylori constituye un buen marcadorgenético para predecir riesgo de enfermedades asociadas a la persistencia del patógeno. Objetivos: Determinar la prevalencia de cagA, vacA, babA2, iceA y dupA en pacientes chilenos, durante 10 años de seguimiento. Métodos: Se analizaron las biopsias gástricas de 1 577 pacientes (183 niños) obtenidas entre enero de 2003 y diciembre de 2007, mediante PCR convencional y cultivo bacteriano. En 374 individuos positivos se investigó la prevalencia de cagA, vacA (s1a, s1b, s2, m1, m2, i1 e i2), babA2, iceA (1 y 2) y dupA. Resultados: La prevalenciade H. pylori en adultos fue 48.7% y un 23.7% de los pacientes presentó más de un cepa bacteriana. La prevalenciapor genes fue: cagA 29.4%, vacAm1 52.7%, vacAm2 61.8%, vacAs1a 46.5%, vacAs1b 28.3%, vacAs2 41.7%, vacAi1 30.9%, vacAi2 12.0%, babA23.5%, iceA1 30.5%, iceA2 61.2% y dupA 28.9%. Se observó un 90% de concordancia en la prevalencia delos genes hpy, cagA, babA2, iceA e iceA2, y un 67.6% para vacAs1a, cuando se comparó biopsia y cultivo como fuente de ADN. Conclusiones: La mayoría de los genes de virulencia han mantenido su prevalencia en el tiempo,excepto vacAm1 y babA2 que la han aumentado. Sin embargo, la prevalencia de babA2 continúa siendo muy baja.
Background: Genes associated with virulence in Helicobacter pylori are good markers for prediction of risk of developing diseases due to persistent infection. Aim: To establish the prevalence of cagA, vacA, babA2,iceA and dupA among Chilean patients over a 10-year period. Methods: 1 577 gastric biopsies (183 children), collected from January 2003 to December 2007, were analyzed by conventional PCR and bacteriological culture. The prevalence of the genes cagA, vacA (s1a, s1b, s2, m1, m2, i1 and i2), babA2, iceA (1 and 2) and dupA were investigated in 374 positive individuals. Results: Prevalence of H. pylori in adults was 48.7%, with 23.7% of them presenting more than one infecting strain. Prevalence of genes was as follows: cagA 29.4%, vacAm152.7%, vacAm2 61.8%, vacAs1a 46.5%, vacAs1b 28.3%, vacAs2 41.7%, vacAi1 30.9%, vacAi2 12.0%, babA2 3.5%, iceA1 30.5%, iceA2 61.2% and dupA 28.9%. Ninety percent of agreement was observed in the prevalence of genes hpy, cagA, babA2, iceA and iceA2, by using DNA from both sources, but was only 67.6% for vacAs1a gene. Conclusion: The results suggest that all the genes conserved their prevalence in this period with the exception of vacAm1 and babA2, in which there was increased prevalence.

En este estudio se realizó un análisis en la variación de la riqueza, composición y abundancia en la comunidad de mariposas para cinco localidades en los llanos orientales colombianos distribuidas así: Haciendas San Antonio (500 msnm), Cafam (200 msnm) y Con Esto Tengo (480 msnm), como bosque de galería, y haciendas Loma Linda (640 msnm) y Buena Vista (1250 msnm) como pie de monte. Para el muestreo se usaron redes caza mariposas y trampas Vansomeren-Rydon, en dos épocas de los años 2003, 2004 y 2005 con visitas de cuatro días por muestreo. Se reporta 469 especímenes distribuidos en seis familias: Hesperidae, Papilionidae, Nymphalidae, Pieridae, Lycaenidae y Riodinidae. En total estas familias se distribuyeron en 37 géneros y 45 especies. Por la composición de ropaloceros los sitios San Antonio, Con esto tengo y Loma Linda presentaron la mayor similitud seguidos de Buena Vista y Cafam, de acuerdo con el análisis de similitud UPGMA, utlizando el coeficiente de Jaccard. Los datos obtenidos revelan la riqueza de la fauna presente en fragmentos de ecosistemas propios de los llanos colombianos, y la necesidad de continuar su seguimiento y monitoreo para plantear planes de manejo y conservación de estas áreas.
