Correlación entre la adicción a la comida y niveles del ácido araquidónico en adultos con obesidad tras intervenciones nutricionales

Introducción: Los endocannabinoides son una diana en el tratamiento de la obesidad y se producen a partir de ácidos grasos esenciales, los derivados del ácido linoleico actúan como agonistas de los receptores cannabinoides tipo 1 (CB1), asimismo, los derivados del ácido linolénico ejercen efectos de antagonistas de dichos receptores, por lo cual se plantea que modificar el consumo dietario de los ácidos grasos omega 3 y 6 podría modular la activación del sistema endocannabinoide, lo que podría ser favorable para personas con adicción a la comida, considerando cómo este sistema promueve la actividad de las vías dopaminérgicas que se alteran en la adicción a sustancias psicoactivas. Objetivo: Analizar la correlación entre el puntaje de adicción a la comida por la escala mYFAS 2.0 y los niveles plasmáticos de ácido araquidónico en adultos con obesidad tras modular la ingesta de alimentos fuente de ácidos grasos esenciales. Metodología: Se desarrolló un estudio piloto con diseño de ensayo clínico cruzado en dos tiempos, en donde los participantes recibieron los tratamientos estándar y experimental, en estos se brindaron planes siguiendo recomendaciones para el manejo nutricional de la obesidad, adicionalmente, el tratamiento experimental contó con pautas para disminuir el consumo del Omega 6 y aumentar el consumo de Omega 3 para obtener una relación menor a 5:1 entre estos ácidos grasos. Resultados: Se observó una disminución significativa en el puntaje de adicción a la comida y los niveles plasmáticos de ácido araquidónico en los participantes tras recibir el tratamiento experimental, presentando una correlación directamente proporcional entre estas, por otro lado, el tratamiento estándar estuvo asociado a una correlación inversamente proporcional entre estos. Conclusiones: El descenso en las concentraciones plasmáticas del ácido araquidónico fue asociado a un menor puntaje en la escala mYFAS 2.0 de adicción a la comida en los participantes de este estudio tras su exposición al tratamiento experimental.

Introduction: Endocannabinoids are a target in obesity treatment and they are produced from the essential fatty acids, the metabolites of linoleic acid act as agonists of the cannabinoid receptors type 1 (CB1), likewise, the metabolites of the linolenic acid act as inverse agonists of such receptors, hence, it is proposed that modifying the dietary intake of the essential fatty acids (Omega 6 and 3) may modulate the activation of the endocannabinoid system, this could be favorable for people with food addiction, considering how this system promotes the activity of the dopaminergic pathways that are altered in the psychoactive substances addiction. Objective: To analyze the correlation between the food addiction score and plasmatic levels of arachidonic acid in adults with obesity following a modulation of the dietary intake of essential fatty acids n-6 and n-3 food sources. Methods: A pilot study was carried out with a two-period crossover clinical trial design, in which the participants received standard and experimental treatments, in these programs, plans were provided following guidelines for the nutritional management of obesity, in addition, the experimental treatment included recommendations to reduce the intake of linoleic acid and to increase the intake of linolenic acid to obtain a ratio lower to 5:1 between these fatty acids. Results: A significant decrease in the food addiction score and plasmatic levels of arachidonic acid was observed in the participants exposed to the experimental treatment, showing a directly proportional correlation, moreover, the standard treatment was associated to inverse correlations between these variables. Conclusion: The decrease in plasmatic arachidonic acid levels was associated with lower scores on the mYFAS 2.0 of food addiction in the participants of this study following their exposure to the experimental treatment.

Dermatoscopic shiny white structures in benign cutaneous tumours.

The dermatoscopic characteristics of shiny white structures (SWS) in malignant skin tumours are well described, but data on benign skin neoplasms are scarce. To evaluate dermatoscopic features of SWS in common benign tumours, we reviewed our database for histopathologically confirmed cases. The dermatoscopic images were evaluated for the presence of any type of SWS. Those images with SWS were further analyzed for their quantity, distribution and shape. Of 2420 evaluated benign tumours, 357 (14.8%) displayed SWS. The highest frequencies were observed in pyogenic granuloma (62/100, 62.0%), angioma (63/113, 55.8%) and adnexal tumours (42/84, 50.0%). The lowest frequency was found in common nevi (16/1032, 1.6%) and solar lentigo (0%). The presence of SWS was not associated with sex or anatomic location. SWS were usually diffuse and multiple. SWS may be present in a broad spectrum of benign tumours. Therefore, they should not be considered as de-facto indicators of malignancy.

[Relevance and feasibility of reforms to create a universal health system in ChileRelevância e viabilidade de uma reforma para a criação de um sistema de saúde universal no Chile]. / Pertinencia y factibilidad de reforma para crear un sistema universal de salud en Chile.

The health system in Chile is well developed, with broad national coverage.

The government's program for 2022-2026 proposes substantial reforms aimed at creating a universal health system. Other reform proposals formulated by various government programs and commissions, as well as think tanks, provide useful inputs to contextualize the government proposal.Different types of models coexist in the health system: public insurance is based on a social security model, the public system provides free care to the insured population, and private insurance and private care providers work on a market basis. The proposed system would function on the national health system model, combining a predominant national health service (Beveridge model) with a complementary social security system (Bismarck model), depending on the need for funding. With a focus on social project evaluation, the relevance (internal coherence and external alignment) and political and economic feasibility of the contents of the government program were reviewed. The proposal has internal coherence, but limited external alignment with the prevailing political and economic system, and little State capacity to increase the financing of public enterprises and their coverage.

Impact of acute psychosocial stress on attentional control in humans. A study of evoked potentials and pupillary response.

Psychosocial stress has increased considerably in our modern lifestyle, affecting global mental health. Deficits in attentional control are cardinal features of stress disorders and pathological anxiety. Studies suggest that changes in the locus coeruleus-norepinephrine system could underlie the effects of stress on top-down attentional control. However, the impact of psychosocial stress on attentional processes and its underlying neural mechanisms are poorly understood. This study aims to investigate the effect of psychosocial stress on attentional processing and brain signatures. Evoked potentials and pupillary activity related to the oddball auditory paradigm were recorded before and after applying the Montreal Imaging Stress Task (MIST). Electrocardiogram (ECG), salivary cortisol, and subjective anxiety/stress levels were measured at different experimental periods. The control group experienced the same physical and cognitive effort but without the psychosocial stress component. The results showed that stressed subjects exhibited decreased P3a and P3b amplitude, pupil phasic response, and correct responses. On the other hand, they displayed an increase in Mismatch Negativity (MMN). N1 amplitude after MIST only decreased in the control group. We found that differences in P3b amplitude between the first and second oddball were significantly correlated with pupillary dilation and salivary cortisol levels. Our results suggest that under social-evaluative threat, basal activity of the coeruleus-norepinephrine system increases, enhancing alertness and decreasing voluntary attentional resources for the cognitive task. These findings contribute to understanding the neurobiological basis of attentional changes in pathologies associated with chronic psychosocial stress.

In your phase: neural phase synchronisation underlies visual imagery of faces.

Mental imagery is the process through which we retrieve and recombine information from our memory to elicit the subjective impression of "seeing with the mind's eye". In the social domain, we imagine other individuals while recalling our encounters with them or modelling alternative social interactions in future. Many studies using imaging and neurophysiological techniques have shown several similarities in brain activity between visual imagery and visual perception, and have identified frontoparietal, occipital and temporal neural components of visual imagery. However, the neural connectivity between these regions during visual imagery of socially relevant stimuli has not been studied. Here we used electroencephalography to investigate neural connectivity and its dynamics between frontal, parietal, occipital and temporal electrodes during visual imagery of faces. We found that voluntary visual imagery of faces is associated with long-range phase synchronisation in the gamma frequency range between frontoparietal electrode pairs and between occipitoparietal electrode pairs. In contrast, no effect of imagery was observed in the connectivity between occipitotemporal electrode pairs. Gamma range synchronisation between occipitoparietal electrode pairs predicted subjective ratings of the contour definition of imagined faces. Furthermore, we found that visual imagery of faces is associated with an increase of short-range frontal synchronisation in the theta frequency range, which temporally preceded the long-range increase in the gamma synchronisation. We speculate that the local frontal synchrony in the theta frequency range might be associated with an effortful top-down mnemonic reactivation of faces. In contrast, the long-range connectivity in the gamma frequency range along the fronto-parieto-occipital axis might be related to the endogenous binding and subjective clarity of facial visual features.

Presente y futuro del tratamiento biológico y moléculas pequeñas en la dermatitis atópica / Present and future of biological treatment and small molecules in atopic dermatitis

La dermatitis atópica (DA) es una condición inflamatoria crónica de la piel de etiología multifactorial. Buscando mejorar la respuesta clínica minimizando los efectos adversos y ampliar el arsenal terapéutico disponible, se ha dado pie al desarrollo de nuevos fármacos con resultados prometedores en la calidad de vida. Los inmunomoduladores sistémicos clásicos son considerados el tratamiento estándar en los casos de DA moderada a severa refractaria al tratamiento con corticoides tópicos. Estos se encasillan dentro de las denominadas moléculas pequeñas, junto con los inhibidores de Janus- en un efecto pleiotrópico en las citoquinas y por ende, no selectivo. Los medicamentos biológicos poseen ventajas frente a los inmunomoduladores clásicos, principalmente su mayor especificidad gracias a la similitud con las moléculas endógenas. Dupilumab se mantiene siendo el único fármaco biológico aprobado por la FDA para el tratamiento de la DA, con una seguridad a corto plazo demostrada. Algunas moléculas nuevas, como el tralokinumab y los inhibidores JAK, presentan resultados prometedores. De este grupo, abrocitinib pareciera posicionarse como una alternativa al menos similar que dupilumab. La creciente investigación de nuevas alternativas ha creado una revolución terapéutica para que nuestros pacientes puedan acceder a una mejor calidad de vida. No obstante, es difícil lograr comprender la efectividad y seguridad de cada uno de los tratamientos disponibles, por la falta de estudios comparativos. La siguiente revisión muestra las nuevas terapias biológicas y algunas moléculas pequeñas con evidencia para su uso en DA

Atopic dermatitis (AD) is a chronic inflammatory condition of the skin with a multifactorial etiology. Seeking to improve the clinical response by minimizing adverse effects and expanding the available therapeutic arsenal, the development of new drugs has led to promising results on quality of life. Classic systemic immunomodulators are considered the standard treatment in cases of moderate to severe AD refractory to treatment with topical corticosteroids. These are classified into molecules, along with Janus kinase inhibitors (JAKs). Small molecules act on intracellular targets, with the inconveniency of producing a pleiotropic effect on cytokines and, therefore, non-selective actions. Biologics have advantages over classical immunomodulators, mainly their greater specificity thanks to the similarity between endogenous molecules. Dupilumab remains the only biologic drug approved by the FDA for the treatment of AD, with demonstrated short-term safety. Some new molecules, such as tralokinumab and JAK inhibitors, have shown promising results. Of this group, abrocitinib seems to be positioned as an alternative at least similar to dupilumab. The current investigation of new alternatives has created a therapeutic revolution so that we can offer our patients a better quality of life. However, it is difficult to understand the efficacy and safety of each of the available treatments due to the lack of comparative studies. The following review shows the new biological therapies and small molecules with evidence for their use in DA.

Association of BoLA DRB3 gene polymorphisms with BoHV-1 infection and zootechnical traits.

BACKGROUND: The dairy sector is one of the leading in agricultural production sectors in the world and the bovine herpesvirus 1 (BoHV-1) is an important pathogen that causes great losses in most production systems. Moreover, BoLA DRB3 immunological gene presents different alleles related to protection against many pathogens. METHODS: Serological diagnosis was carried out to determine the BoHV-1 infection and through PCR-RFLP 506 Holstein cows from several municipalities of Antioquia were genotyped for BoLA DRB3.2 gene polymorphisms. RESULTS: Alleles 8, 16, 22, and 24 were the most common out of the 42 alleles found. By indirect ELISA technique, a 58.7% prevalence of BoHV-1 infection in this population was diagnosed and Odd ratios for found alleles were calculated by logistic regression; the only significant association was held for allele 37, which showed that it effects confers susceptibility to infection. On the other hand, by using generalized linear models, a significant association between BoLA DRB3.2 gene and milk and fat yield in primiparous and services per conception in multiparous was found, with the most favorable alleles being 11 and 28 in primiparous and 22 and 28 in multiparous; allele 37 was unfavorable only in primiparous. CONCLUSION: BoLA DRB3.2 gene polymorphisms have shown high variability and significant effects on Holstein cattle and their performance in production systems in Antioquia are at both sanitary or health and productive levels.

Off-Line Evaluation of Mobile-Centric Indoor Positioning Systems: The Experiences from the 2017 IPIN Competition.

The development of indoor positioning solutions using smartphones is a growing activity with an enormous potential for everyday life and professional applications. The research activities on this topic concentrate on the development of new positioning solutions that are tested in specific environments under their own evaluation metrics. To explore the real positioning quality of smartphone-based solutions and their capabilities for seamlessly adapting to different scenarios, it is needed to find fair evaluation frameworks. The design of competitions using extensive pre-recorded datasets is a valid way to generate open data for comparing the different solutions created by research teams. In this paper, we discuss the details of the 2017 IPIN indoor localization competition, the different datasets created, the teams participating in the event, and the results they obtained. We compare these results with other competition-based approaches (Microsoft and Perf-loc) and on-line evaluation web sites. The lessons learned by organising these competitions and the benefits for the community are addressed along the paper. Our analysis paves the way for future developments on the standardization of evaluations and for creating a widely-adopted benchmark strategy for researchers and companies in the field.

Draft genome sequences of clostridium strains native to Colombia with the potential to produce solvents.

Genomes from four Clostridium sp. strains considered to be mesophilic anaerobic bacteria, isolated from crop soil in Colombia, with a strong potential to produce alcohols like 1,3-propanediol, were analyzed. We present the draft genome of these strains, which will be useful for developing genetic engineering strategies.

Brain signatures of moral sensitivity in adolescents with early social deprivation.

The present study examined neural responses associated with moral sensitivity in adolescents with a background of early social deprivation. Using high-density electroencephalography (hdEEG), brain activity was measured during an intentional inference task, which assesses rapid moral decision-making regarding intentional or unintentional harm to people and objects. We compared the responses to this task in a socially deprived group (DG) with that of a control group (CG). The event-related potentials (ERPs) results showed atypical early and late frontal cortical markers associated with attribution of intentionality during moral decision-making in DG (especially regarding intentional harm to people). The source space of the hdEEG showed reduced activity for DG compared with CG in the right prefrontal cortex, bilaterally in the ventromedial prefrontal cortex (vmPFC), and right insula. Moreover, the reduced response in vmPFC for DG was predicted by higher rates of externalizing problems. These findings demonstrate the importance of the social environment in early moral development, supporting a prefrontal maturation model of social deprivation.

Determination of the species from skeletal remains through histomorphometric evaluation and discriminant analysis / Determinación de la especie a partir de restos óseos mediante evaluación histomorfométrica y análisis discriminante

In situations where the skeletal remains found are too fragmented, it is necessary to assess the human origin of such remains; for this purpose, various parameters are used, both anatomical and histological. The objective of the present study is to evaluate the various histomorphometric parameters to differentiate human from non-human bones, to further construct discriminatory functions that allow interspecies classification. Tibia bones sections from human, bovine, pig, hen, cat, and dog species were used, processed through conventional histological techniques and observed under the microscope with a 40x magnification, analyzing the Haversian Canal Density parameters by mm2, Diameter of the Haversian Canal and the Diameter of the Haversian System which were compared through one way ANOVA with Scheffé post test, p<0.05. Subsequently, the discriminatory functions were constructed for each species and the percentage of well-diagnosed cases was determined. Meaningful differences were found in the parameters analyzed; the discriminatory functions allowed to correctly classify 88.5 percent of the cases. Our results suggest that it is possible to differentiate human skeletal remains from non-human through the observation of their histological characteristics and histomorphometric parameters, but interspecies differentiation requires a more complex analysis...

En situaciones donde los restos óseos que se encuentran están muy fragmentados, es necesario evaluar el origen humano de dichos restos, para ello se utilizan diversos parámetros morfológicos tanto anatómicos como histológicos. El propósito de este estudio fue evaluar los distintos parámetros histomorfométricos para diferenciar hueso humano de no humano, para posteriormente construir las funciones discriminantes que permitan la clasificación interespecies. Se utilizaron secciones de hueso de tibia de individuos de especies: humano, bovino, cerdo, gallina, gato y perro, procesadas mediante técnica histológica convencional y observadas al microscópio con aumento 40x, analizándose los parámetros Densidad del canal de Havers por mm2, Diámetro del canal de Havers y diámetro del sistema Haversiano, los cuales fueron comparados mediante one way ANOVA con Scheffé post test con p<0,05. Posteriormente se construyeron las funciones discriminantes para cada especie y se determinó el porcentaje de casos bien diagnosticados. Se encontraron diferencias significativas en los parámetros analizados, las funciones discriminantes permitieron la correcta clasificación del 88,5 por ciento de los casos. Nuestros resultados sugieren que es posible diferenciar restos óseos humanos de no humanos mediante la observación de sus características histológicas y parámetros histomorfométricos, pero la diferenciación interespecie requiere de análisis más complejo...

Resultados. Encontramos que las mujeres autóctonas realizan un correcto control integral del embarazo en el 92,1% (164) de los casos frente al 63,4% (109) de las inmigrantes (χ2=42,172; gl=1; p=0,000). El 87,5% (287) del total de satisfechas piensan que el interés de la matrona es mejor o mucho mejor de lo que se esperaban (χ2=102,466; gl=4; p=0,000). El 95,81% (320) de las mujeres satisfechas recomendarían el hospital, mientras que el total de las no satisfechas tienen dudas (χ2=93,680; gl=2; p=0,000). Conclusiones. Las variables sociodemográficas no influyen en la satisfacción global de las mujeres, exceptuando la edad. En general tanto las mujeres autóctonas como inmigrantes se encuentran satisfechas con la atención recibida en el área de partos del CHUA (AU)

Aim. To describe the level of satisfaction of women who come to the University Hospital of Albacete (CHUA), as regards the health carereceived upon admission for giving birth and during the immediate postnatal period, and to evaluate if the socio-demographic variable has an influence on user satisfaction of the delivery room service. Method. Descriptive and cross-sectional study carried out through an interview in order to obtain data on the socio-demographic, obstetric and gynaecological variables, together with a satisfaction questionnaire for women in the puerperium period at the CHUA, reference hospital of the Health Area in Albacete, in the Obstetrics Service. The selection was made by systematic sampling, in which immigrants and Spanish born women were enrolled according to the inclusion criteria. Results We found that 92.1% (164) of Spanish-born women carry out a proper integral control of pregnancy, compared to 63.4% (109) of immigrants (χ2=42.172; gl=1; P=.000). The majority (87.5%, 287) of the total number of satisfied women thought that the midwife interest was better or much better than they expected (χ2=102.466; gl=4; P=.000). The large majority of satisfied women (95.81%, 320) would recommend the hospital, while the number of unsatisfied women had doubts (χ2=93.680; gl=2; P=.000). Conclusions. The socio-demographic variables did not appear to have an influence on the overall satisfaction of the women, except for the age. In general, both the autochthonous and immigrant women were satisfied with the attention received in the CHUA Delivery room (AU)

The selection was made by systematic sampling, in which immigrants and Spanish born women were enrolled according to the inclusion criteria. RESULTS: We found that 92.1% (164) of Spanish-born women carry out a proper integral control of pregnancy, compared to 63.4% (109) of immigrants (χ(2)=42.172; gl=1; P=.000). The majority (87.5%, 287) of the total number of satisfied women thought that the midwife interest was better or much better than they expected (χ(2)=102.466; gl=4; P=.000). The large majority of satisfied women (95.81%, 320) would recommend the hospital, while the number of unsatisfied women had doubts (χ(2)=93.680; gl=2; P=.000). CONCLUSIONS: The socio-demographic variables did not appear to have an influence on the overall satisfaction of the women, except for the age. In general, both the autochthonous and immigrant women were satisfied with the attention received in the CHUA Delivery room.

Helicobacter pylori HopE and HopV porins present scarce expression among clinical isolates.

AIM: To evaluate how widely Helicobacter pylori (H. pylori) HopE and HopV porins are expressed among Chilean isolates and how seroprevalent they are among infected patients in Chile. METHODS: H. pylori hopE and hopV genes derived from strain CHCTX-1 were cloned by polymerase chain reaction (PCR), sequenced and expressed in Escherichia coli AD494 (DE3). Gel-purified porins were used to prepare polyclonal antibodies. The presence of both genes was tested by PCR in a collection of H. pylori clinical isolates and their expression was detected in lysates by immunoblotting. Immune responses against HopE, HopV and other H. pylori antigens in sera from infected and non-infected patients were tested by Western blotting using these sera as first antibody on recombinant H. pylori antigens. RESULTS: PCR and Western blotting assays revealed that 60 and 82 out of 130 Chilean isolates carried hopE and hopV genes, respectively, but only 16 and 9, respectively, expressed these porins. IgG serum immunoreactivity evaluation of 69 H. pylori-infected patients revealed that HopE and HopV were infrequently recognized (8.7% and 10.1% respectively) compared to H. pylori VacA (68.1%) and CagA (59.5%) antigens. Similar values were detected for IgA serum immunoreactivity against HopE (11.6%) and HopV (10.5%) although lower values for VacA (42%) and CagA (17.4%) were obtained when compared to the IgG response. CONCLUSION: A scarce expression of HopE and HopV among Chilean isolates was found, in agreement with the infrequent seroconversion against these antigens when tested in infected Chilean patients.
