Estudios clínicos sobre la enfermedad celíaca (2014-2019): revisión sistemática de la prevalencia de la presentación clínica y enfermedades asociadas por edades

Introduction: Celiac disease (CD) is characterized by a wide variety of signs, symptoms and associated diseases in its presentation, it can even be asymptomatic. Recent studies show the variation of the clinical spectrum according to age. In young children, classic celiac disease predominates with symptoms such as abdominal distension, decreased appetite, diarrhea and weight loss. Frequent atypical manifestations in older children are abdominal pain, constipation, reflux, vomiting, fatigue and short stature. In adults there is a reduction in the classical presentation and an increase in the non-classical.Material and methods: A systematic review was conducted in which articles on signs and symptoms of classical and atypical CD in children and adults have been included, in addition to the diseases that are frequently associated with this pathology. The databases used to search the articles were PubMed, Web of Science and Scopus, from the last six years (2014-2019). A total of 164 articles have been evaluated following the selection criteria, of which the 20 most relevant articles have been included in the study.Results: CD is diagnosed more frequently in women and at earlier ages than men. In children under two years old, classical CD predominates although more intensely than in young children. In older children, teenagers and adults, the form of presentation changes towards atypical or non-classical and asymptomatic.Conclusions: The increased prevalence in the last years, great heterogeneity of symptoms, associated diseases and the variation of the clinical spectrum towards an atypical form with extraintestinal symptoms causes delay in its diagnosis so they must be recognized to be detected earlier.Introducción: La enfermedad celíaca (EC) se caracteriza por una gran variedad de signos, síntomas y enfermedades asociadas en su forma de presentación, incluso puede cursar de forma asintomática. Recientes estudios muestran la variación del espectro clínico según la edad. En niños y niñas pequeñas predomina la forma clásica con síntomas como distensión abdominal, disminución del apetito, diarrea y pérdida de peso. Las manifestaciones atípicas frecuentes en niños mayores son dolor abdominal, estreñimiento, reflujo, vómitos, fatiga, talla baja. En adultos se observa una reducción de la forma de presentación clásica e incremento de la no clásica.Material y métodos: Se realizó una revisión sistemática en la que se han incluido los artículos sobre signos y síntomas de la EC clásica y atípica en niños y adultos, además de las enfermedades que se asocian de forma frecuente a esta patología. Las bases de datos utilizadas para la búsqueda de los artículos fueron PubMed, Web of Science y Scopus, de los últimos seis años (2014-2019). Se han evaluado un total de 164 artículos tras los criterios de selección, de los cuales se han incluido en el estudio los 20 artículos más relevantes.Resultados: La EC se diagnostica con mayor frecuencia en mujeres y a edades más tempranas que a los hombres. En niños menores de dos años predomina la EC clásica, aunque de forma más intensa que en niños y niñas pequeñas. En niños y niñas mayores, adolescentes y edad adulta varía la forma de presentación hacia la atípica o no clásica y asintomática.Conclusiones: El incremento en la prevalencia en los últimos años, gran heterogeneidad de síntomas, enfermedades asociadas y la variación del espectro clínico hacia una forma atípica con síntomas extraintestinales causa retraso en su diagnóstico por lo que deben reconocerse para que se detecte de manera más precoz

Perturbation of hypothalamic MicroRNA expression patterns in male rats after metabolic distress: impact of obesity and conditions of negative energy balance

[Abstract] The hypothalamus plays a crucial role in body weight homeostasis through an intricate network of neuronal circuits that are under the precise regulation of peripheral hormones and central transmitters. Although deregulated function of such circuits might be a major contributing factor in obesity, the molecular mechanisms responsible for the hypothalamic control of energy balance remain partially unknown. MicroRNAs (miRNAs) have been recognized as key regulators of different biological processes, including insulin sensitivity and glucose metabolism. However, the roles of miRNA pathways in the control of metabolism have been mostly addressed in peripheral tissues, whereas the potential deregulation of miRNA expression in the hypothalamus in conditions of metabolic distress remains as yet unexplored. In this work, we used high-throughput screening to define to what extent the hypothalamic profiles of miRNA expression are perturbed in two extreme conditions of nutritional stress in male rats, namely chronic caloric restriction and high-fat diet–induced obesity. Our analyses allowed the identification of sets of miRNAs, including let-7a, mir-9*, mir-30e, mir-132, mir-145, mir-200a, and mir-218, whose expression patterns in the hypothalamus were jointly altered by caloric restriction and/or a high-fat diet. The predicted targets of these miRNAs include several elements of key inflammatory and metabolic pathways, including insulin and leptin. Our study is the first to disclose the impact of nutritional challenges on the hypothalamic miRNA expression profiles. These data will help to characterize the molecular miRNA signature of the hypothalamus in extreme metabolic conditions and pave the way for targeted mechanistic analyses of the involvement of deregulated central miRNAs pathways in the pathogenesis of obesity and related disorders.Instituto de Salud Carlos III; PI10/00088Ministerio de Economia y Competitividad; IN845B-2010/187Instituto de Salud Carlos III; PI13/00322FISXunta de Galicia; 10CSA916014PRXunta de Galicia; EM2013/011Ministerio de Ciencia e Innovación; BFU 2011-2502

Gender Training in Movement. Gender Model at the UACJ and its Development in the Bachelor in Sport Training in Ciudad Juarez

El deporte permite una variedad de estrategias de uso social. Una de ellas, el conformarse como una herramienta pedagógica pertinente para constituir una perspectiva de género. Ciertamente, para ello se requiere una política institucional, que constituye acciones, procesos que pueden llegar a influir en una comunidad universitaria. En este trabajo el objetivo es analizar cómo es que se ha desarrollado la Política de género en la Universidad Autónoma de Ciudad Juárez, con una metodología con enfoque descriptivo desde la revisión de documentos fundantes y operativos de dicha política y aquellas estrategias alternas. Se discute cómo es que este proceso se ubica dentro del Programa de Licenciatura en Entrenamiento Deportivo, en donde se forma a los futuros/as profesores/as de educación física, dentro de un contexto regional, en México, abatido por inseguridad pública y los feminicidios. Se concluye sobre las áreas de oportunidad que la política de género que se desarrolla en la UACJ debe establecer, para constituir una cultura de género que impacte tanto a estudiantes como a docentes.Sport allows a variety of strategies for social use. One of them is to be trained as a relevant pedagogical instrument to constitute a gender perspective. Certainly, this requires an institutional policy which constitutes actions and processes that can influence a university community. In this work, the objective is to analyze how the Gender Policy has been developed at the Universidad Autónoma de Ciudad Juarez, with a descriptive-approach methodology by means of the review of founding and operational documents of said policy and those alternative strategies. The ways through which this process is located within the Sport Training Bachelor Program is discussed, where future Physical Education teachers are trained within a Mexican regional context, struck down by public insecurity and femicides. The work concludes that the areas of opportunity that the gender policy developed at the UACJ have not yet allowed to establish a broad gender culture, in the training element of trainers themselves at the institution.Facultad de Humanidades y Ciencias de la Educació

Uloga karotenoida iz ekstrakta mesa bundeve u zaštiti od oštećenja krvno-moždane barijere uzrokovane mikotoksinima in vitro

Some mycotoxins such as beauvericin (BEA), ochratoxin A (OTA), and zearalenone (ZEA) can cross the blood brain barrier, which is why we tested the anti-inflammatory action of a pumpkin carotenoid extract (from the pulp) against these mycotoxins and their combinations (OTA+ZEA and OTA+ZEA+BEA) on a blood brain barrier model with co-cultured ECV304 and C6 cells using an untargeted metabolomic approach. The cells were added with mycotoxins at a concentration of 100 nmol/L per mycotoxin and pumpkin carotenoid extract at 500 nmol/L. For control we used only vehicle solvent (cell control) or vehicle solvent with pumpkin extract (extract control). After two hours of exposure, samples were analysed with HPLC-ESI-QTOF-MS. Metabolites were identified against the Metlin database. The proinflammatory arachidonic acid metabolite eoxin (14,15-LTE4) showed lower abundance in ZEA and BEA+OTA+ZEA-treated cultures that also received the pumpkin extract than in cultures that were not treated with the extract. Another marker of inflammation, prostaglandin D2-glycerol ester, was only found in cultures treated with OTA+ZEA and BEA+OTA+ZEA but not in the ones that were also treated with the pumpkin extract. Furthermore, the concentration of the pumpkin extract metabolite dihydromorelloflavone significantly decreased in the presence of mycotoxins. In conclusion, the pumpkin extract showed protective activity against cellular inflammation triggered by mycotoxins thanks to the properties pertinent to flavonoids contained in the pulp.Pojedini mikotoksini poput bovericina (BEA), okratoksina A (OTA) i zearalenona (ZEA) prelaze krvno-moždanu barijeru, a to je i razlog zbog kojega smo istražili djelovanje ekstrakta karotenoida iz mesa bundeve protiv upalnih procesa izazvanih ovim mikotoksinima i njihovim kombinacijama (OTA+ZEA i OTA+ZEA+BEA) na modelu krvno-moždane barijere koji se sastojao od kultura stanica ECV304 i C6, oslanjajući se pritom na neciljani metabolomički pristup. Stanice su tretirane mikotoksinima u koncentraciji od 100 nmol/L po mikotoksinu odnosno ekstraktom karotenoida u koncentraciji od 500 nmol/L. Za kontrolu smo upotrijebili samo otapalo (stanična kontrola) odnosno otapalo s bundevinim ekstraktom (ekstraktna kontrola). Nakon dva sata tretmana uzorci su analizirani metodom tekućinske kromatografije / masene spektrometrije (HPLC-ESI-QTOF-MS), a dobiveni metaboliti identificirani su usporedbom s bazom podataka Metlin. Primjena ekstrakta značajno je smanjila količinu metabolita proupalne arahidonske kiseline eoksina (14,15-LTE4) u kulturama tretiranima samo zearalenonom odnosno kombinacijom BEA+OTA+ZEA. Drugi upalni biljeg, prostaglandin D2-glicerol ester, otkriven je samo u kulturama tretiranima kombinacijama OTA+ZEA odnosno BEA+OTA+ZEA, ali ne i u onima koje su usto tretirane bundevinim ekstraktom. Osim toga, u prisutnosti mikotoksina značajno je porasla koncentracija metabolita dihidromoreloflavona iz bundevina ekstrakta. Time je taj ekstrakt iskazao zaštitno djelovanje protiv stanične upale uzrokovane mikotoksinima zahvaljujući svojstvima flavonoida koji se nalaze u njezinu mesu

‘Physio-EndEA’ Study: A Randomized, Parallel-Group Controlled Trial to Evaluate the Effect of a Supervised and Adapted Therapeutic Exercise Program to Improve Quality of Life in Symptomatic Women Diagnosed with Endometriosis

This research was funded by the Health Institute Carlos III (FEDER funds), grant number PI17/01743, and donations from particular endometriosis women that believed in this project from the beginning. It was also partly supported by funds from the PAIDI group CTS-206 (Oncologia Basica y Clinica). This study takes place thanks to the additional funding from the University of Granada, Plan Propio de Investigacion 2016, Excellence actions: Units of Excellence; Unit of Excellence on Exercise and Health (UCEES).Aim: The ‘Physio-EndEA’ study aims to explore the potential benefits of a therapeutic exercise program (focused on lumbopelvic stabilization and tolerance to exertion) on the health-related quality of life (HRQoL) of symptomatic endometriosis women. Design: The present study will use a parallel-group randomized controlled trial design. Methods: A total of 22 symptomatic endometriosis women will be randomized 1:1 to the Physio-EndEA or usual care groups. The ‘Physio-EndEA’ program will consist of a one-week lumbopelvic stabilization learning phase followed by an eight-week phase of stretching, aerobic and resistance exercises focused on the lumbopelvic area that will be sequentially instructed and supervised by a trained physiotherapist (with volume and intensity progression) and adapted daily to the potential of each participant. The primary outcome measure is HRQoL. The secondary outcome measures included clinician-reported outcomes (pressure pain thresholds, muscle thickness and strength, flexibility, body balance and cardiorespiratory fitness) and patient-reported outcomes (pain intensity, physical fitness, chronic fatigue, sexual function, gastrointestinal function and sleep quality). Discussion: Findings of this study will help to identify cost-effective non-pharmacological options (such as this exercise-based intervention) that may contribute to the improvement of HRQoL in symptomatic endometriosis women.Health Institute Carlos III (FEDER funds) PI17/01743PAIDI groupUniversity of Granad

Co-expression gene network analysis reveals novel regulatory pathways involved in porto-sinusoidal vascular disease

[Background & Aims] Porto-sinusoidal vascular disease (PSVD) is a rare vascular liver disease of unknown etiology that causes portal hypertension. It usually affects young individuals and shortens live expectancy. The deregulated pathways involved in PSVD development are unknown and therefore we lack curative treatments. The purpose of this study was to integrate transcriptomic and clinical data by comprehensive network-based modeling in order to uncover altered biological processes in patients with PSVD.[Methods] We obtained liver tissue samples from 20 consecutive patients with PSVD and 21 sex- and age-matched patients with cirrhosis and 13 histologically normal livers (HNL) (initial cohort) and performed transcriptomic analysis. Microarray data were analyzed using weighted gene correlation network analysis to identify clusters of highly correlated genes differently expressed in patients with PSVD. We next evaluated the molecular pathways enriched in patients with PSVD and the core-related genes from the most significantly enriched pathways in patients with PSVD. Our main findings were validated using RNA sequencing in a different cohort of PSVD, cirrhosis and HNL (n = 8 for each group).[Results] Patients with PSVD have a distinctive genetic profile enriched mainly in canonical pathways involving hemostasis and coagulation but also lipid metabolism and oxidative phosphorylation. Serpin family (SERPINC1), the apolipoproteins (APOA, APOB, APOC), ATP synthases (ATP5G1, ATP5B), fibrinogen genes (FGB, FGA) and alpha-2-macroglobulin were identified as highly connective genes that may have an important role in PSVD pathogenesis.[Conclusion] PSVD has a unique transcriptomic profile and we have identified deregulation of pathways involved in vascular homeostasis as the main pathogenic event of disease development. [Lay summary] Porto-sinusoidal vascular disease is a rare but life-shortening disease that affects mainly young people. Knowledge of the disrupted pathways involved in its development will help to identify novel therapeutic targets and new treatments. Using a systems biology approach, we identify that pathways regulating endothelial function and tone may act as drivers of porto-sinusoidal vascular disease.This study was supported by the Instituto de Salud Carlos III FIS PI17/00398, the Ministry of Education and Science, Spain (SAF-2016-75767-R); Agència de Gestió d’Ajuts Universitaris i de Recerca (AGAUR-SGR2017-517) a grant from Generalitat de Catalunya, Fondo Europeo de Desarrollo Regional (FEDER) and Centro de Investigación Biomédica en Red de Enfermedades Hepáticas y Digestivas (CIBERehd), funded by Instituto de Salud Carlos III.

Hypothalamic miR-30 regulates puberty onset via repression of the puberty-suppressing factor, Mkrn3.

Mkrn3, the maternally imprinted gene encoding the makorin RING-finger protein-3, has recently emerged as putative pubertal repressor, as evidenced by central precocity caused by MKRN3 mutations in humans; yet, the molecular underpinnings of this key regulatory action remain largely unexplored. We report herein that the microRNA, miR-30, with three binding sites in a highly conserved region of its 3' UTR, operates as repressor of Mkrn3 to control pubertal onset. Hypothalamic miR-30b expression increased, while Mkrn3 mRNA and protein content decreased, during rat postnatal maturation. Neonatal estrogen exposure, causing pubertal alterations, enhanced hypothalamic Mkrn3 and suppressed miR-30b expression in female rats. Functional in vitro analyses demonstrated a strong repressive action of miR-30b on Mkrn3 3' UTR. Moreover, central infusion during the juvenile period of target site blockers, tailored to prevent miR-30 binding to Mkrn3 3' UTR, reversed the prepubertal down-regulation of hypothalamic Mkrn3 protein and delayed female puberty. Collectively, our data unveil a novel hypothalamic miRNA pathway, involving miR-30, with a prominent role in the control of puberty via Mkrn3 repression. These findings expand our current understanding of the molecular basis of puberty and its disease states
