Structural Features of Diacyldodecaheterocycles with Pseudo-C2-Symmetry: Promising Stereoinductors for Divergent Synthesis of Chiral Alcohols.

Pseudo-C2-symmetric dodecaheterocyclic structures, which possess two acyl/aroyl groups disposed on either a cis- or trans-relative configuration, were prepared from the naturally occurring (-)-(1R)-myrtenal. Addition of Grignard reagents (RMgX) to the diastereoisomeric mixture of these compounds unexpectedly showed that nucleophilic additions to the two prochiral carbonyl centers gave the same stereochemical result in both cis/trans diastereoisomers, making unnecessary the separation of this mixture. Noticeably, both carbonyl groups showed different reactivity because one of them is attached to an acetalic carbon and the other to a thioacetalic carbon. Furthermore, addition of RMgX to the carbonyl attached to the former carbon takes place through the re face, while addition to the second one proceeds through the si face, thus affording the corresponding carbinols in a highly diastereoselective process. This structural feature allowed the sequential hydrolysis of both carbinols, yielding separately (R)- and (S)-1,2-diols after reduction with NaBH4. The mechanism of the asymmetric Grignard addition was explained by density functional theory calculations. This approach contributes to the development of the divergent synthesis of structurally and/or configurationally different chiral molecules.

Is Skull Vibration-Induced Nystagmus Useful in Vestibular Neuritis Follow Up?

The aim of this study was to evaluate the vestibulo-ocular reflex (VOR) gain and the saccade regrouping pattern PR score of the Video Head Impulse Test (vHIT) and its relationship with the slow-phase velocity (SPV) of skull vibration-induced nystagmus (SVIN) in recovery after a unilateral vestibular loss (UVL). A total of 36 patients suffering from vestibular neuritis (VN) were recruited and followed up for twelve months. In every visit, horizontal vHIT and an SVIN were performed, as well as VOR gain; PR score and the SPV of SVIN were measured. We observed a positive association between the VOR gain difference and the SPV of SVIN over time (probability greater than 0.86). Additionally, we obtained a positive association between the SPV of SVIN and the PR score in successive visits (odds ratio (OR) = -0.048; CI [0.898, 1.01]), with a probability of 0.95. Our results confirm that SPV of SVIN; VOR gain difference; and PR score decrease over time after a UVL. Both tests are useful in the follow-up of VN, as they could reflect its clinical compensation or partial recovery.

Langerhans cell histiocytosis of the head and neck in the pediatric population in a tertiary center: Clinical presentation, classification and treatment.

INTRODUCTION: Langerhans cell histiocytosis (LCH) is a rare disease of unknown etiology with a heterogeneous and unspecific clinical presentation. Any organ or system may be involved but the most frequent is the skeleton. The diagnostic gold standard is done through histopathology combined with immunohistochemistry in the correct clinical setting. Treatment is still controversial. The objective of this study is to present a series of pediatric patients in order to contribute to the diagnosis and treatment of LCH. MATERIAL AND METHODS: A longitudinal, descriptive and retrospective study was done in 20 pediatric patients histologically diagnosed of LCH int the last 10 years, in a tertiary center. A review of the medical history was done and data collection included: epidemiological data, clinical manifestations and classification, lesion characteristics, treatment employed, follow-up and evolution. RESULTS: The mean age presentation was 6.5 years (2-12). The most frequent disease presentation was a palpable skull tumor followed by headache. Other otorhinolaryngologic presenting symptoms were bloody otorrhea and post auricular swelling. Single-systems LCH with skull tumors was the most frequent classification. Treatment options (surgery, chemotherapy and corticosteroid infiltration) were indicated according to disease classification. CONCLUSION: LCH should be suspected in pediatric patients with a palpable cranial vault tumor, as well as in patients with chronic otorrhea with granulation tissue at the external ear canal. Management of LCH fundamentally includes chemotherapy and surgery, or the combination of both. High-risk organs lesions, including temporal bone lesions, and multi-system LCH are predictors of recurrence and should have a long-term follow-up.

Antinociceptive activity of the ethanolic extract of Trixis angustifolia DC.

The antinociceptive activity of the ethanolic extract of Trixis angustifolia DC. (EETx) was investigated using the acetic acid-induced writhing and the hot-plate tests in mice. In the acetic acid-induced writhing test, mice treated with EETx (50, 100 and 200 mg/kg, p.o.) exhibited reduced writhing (38%, 67%, and 74%, respectively). In the hot-plate test, the three doses administrated increased the nociceptive response time. The phytochemical analysis of EETx led to the isolation of three known compounds, hygric acid (1), 5,6-Dihydroxy-7,8,4'-trimethoxyflavone (2) and xanthomicrol (3). Compound 1 was identified for the first time in this species. These results demonstrate that T. angustifolia has potential central and peripheral antinociceptive effects and support the ethnomedicinal use of this plant.

Results of High-Protein, High-Calorie Oral Nutritional Supplementation in Malnourished Older People in Nursing Homes: An Observational, Multicenter, Prospective, Pragmatic Study (PROT-e-GER).

OBJECTIVES: To assess if the impact of oral nutritional supplements (ONS) on nutritional and functional status in malnourished older persons living in nursing homes shown by clinical trials are also found outside a trial setting. DESIGN: Observational, multicenter, prospective, pragmatic study. SETTING AND PARTICIPANTS: This study was carried out in 38 nursing homes throughout Spain. Nursing home physicians recruited consecutive residents, older than 65 years, with a diagnosis of malnutrition, when a clinical decision to start ONS had been taken after unsuccessful initial management with dietary interventions. INTERVENTION: The participants received daily 2 bottles of an energy-rich, high-protein commercial ONS for 3 months. MEASURES: Primary outcomes were changes in nutritional status [body weight, body mass index (BMI), and Mini Nutritional Assessment-Short Form (MNA-SF)]; secondary outcomes were functional changes [Functional Ambulation Classification, Barthel index, handgrip strength, and Short Physical Performance Battery (SPPB)], as well as safety and adherence after 12 weeks of follow-up. RESULTS: A total of 282 residents (median age 86 years, 67% women) were included, and 244 (86.5%) completed the follow-up. At baseline, 77.3% of the participants were malnourished (BMI 19.7 kg/m2, interquartile range 18.3-21.8). After 12 weeks of follow-up, participants experienced significant increases in body weight (2.6 ± 3.1 kg, 5.2 ± 5.9%), BMI (1.0 ± 1.2 kg/m2) and MNA-SF (4.0 ± 2.5 points). There were also significant improvements in functional status measured by the Barthel index, handgrip strength, SPPB, and gait speed. Good adherence was registered in 94.6% of the participants. No relevant side effects were found. CONCLUSIONS AND IMPLICATIONS: Improvements in nutritional and functional status can be found when using a high-protein, high-calorie ONS in older undernourished people living in nursing homes.

OBJETIVO: Analizar la prevalencia en práctica clínica de los factores de riesgo cardiovascular (FRCV) y la enfermedad cardiovascular (ECV), así como su relación causal, en la visita de inclusión. MATERIAL Y MÉTODOS: Análisis transversal de la visita de inclusión de los 8.066 pacientes de 18 a 85años de edad incluidos en el estudio IBERICAN. Se analizó la información socio-demográfica, los antecedentes personales y familiares, y la prevalencia de FRCV, de ECV y de enfermedad renal. Se ha realizado un análisis multivariante, mediante regresión logística que incluía la variable comunidad autónoma como variable de efectos aleatorios, para analizar el impacto de determinadas variables en el desarrollo de cada FRCV, síndrome metabólico, lesión de orden subclínica (LOS), enfermedad renal y ECV. RESULTADOS: La dislipemia fue 2,4 veces más frecuente en diabéticos y se incrementó el riesgo un 59% en hipertensos. La hipertensión arterial fue dos veces más frecuente en diabéticos y se incrementó un 94% en hiperuricémicos y un 62,1% en dislipémicos. La diabetes mellitus fue 2,5 veces mayor en dislipémicos y 2,2 veces mayor en hipertensos. La ECV fue cuatro veces más frecuente en pacientes con antecedentes familiares, y se incrementó un 90,8% el riesgo en mujeres y un 53,8% en pacientes con enfermedad renal. CONCLUSIONES: La población española asistida en atención primaria (AP) que ha sido analizada en el estudio IBERICAN presenta una elevada prevalencia de FRCV y ECV establecida, lo que le confiere un elevado RCV. El análisis multivariante realizado muestra una estrecha relación causal entre los FRCV entre sí y con la enfermedad renal y la ECV

OBJECTIVE: To analyse the prevalence in clinical practice of cardiovascular risk factors (CVRF) and cardiovascular disease (CVD), as well as their causal relationship, in the study inclusion visit. MATERIAL AND METHODS: Cross-sectional analysis of the study inclusion visit of 8,066 patients of 18 to 85years of age included in the IBERICAN study. By reviewing the medical history, analytics and medical visits, the patient's physician has collected socio-demographic information, personal and family history and prevalence of CVRF and CVD and renal disease. A multivariate analysis was carried out using a logistic regression that included the autonomous region variable as a random effect variable, in order to analyse the impact of certain variables on the development of each CVRF, metabolic syndrome, subclinical organ damage, renal disease, and CVD. RESULTS: Dyslipidaemia was 2.4 times more frequent in diabetics, and the risk was increased by 59% in hypertensive patients. Arterial hypertension was twice as frequent in diabetics, and increased 94% in hyperuricaemic patients and 62.1% in dyslipidaemia patients. Diabetes mellitus was 2.5 times higher in dyslipidaemia patients, and 2.2 times higher in hypertensive patients. CVD was four times more frequent in patients with a family history, and the risk in women was increased by 90.8% and by 53.8% in patients with renal disease. CONCLUSIONS: The Spanish population seen in Primary Care that were analysed in the IBERICAN study had a high prevalence of CVRF and CVD, which gives it a high CVR. The multivariate analysis performed shows a close causal relationship between the CVRF with each other, and with renal disease and CVD

Prevalence of hypotension in hypertensive treated patients within the Primary Care setting. The PRESCAP 2010 study / Prevalencia de hipotensión en pacientes tratados con hipertensión atendidos en el ámbito de la atención primaria. El estudio PRESCAP 2010

OBJECTIVE: To determine the prevalence of hypotension and associated factors in hypertensive patients treated in the Primary Care setting. MATERIALS AND METHODS: A cross-sectional, descriptive, and multicentre study was conducted with a total of 2635 general practitioners consecutively including 12,961 hypertensive patients treated in a Primary Care setting in Spain. An analysis was performed on the variables of age, gender, weight, height, body mass index, waist circumference, cardiovascular risk factors (diabetes, dyslipidaemia, smoking, obesity, sedentary lifestyle), fasting plasma glucose, complete lipid profile, as well as the presence of target organ damage (left ventricular hypertrophy, microalbuminuria, carotid atherosclerosis) and associated clinical conditions. Hypotension was defined as a systolic blood pressure less than 110mmHg or a diastolic blood pressure less than 70mmHg. A multivariate analysis was performed to determine the variables associated with the presence of hypotension. RESULTS: The mean age was 66.2 years, and 51.7% of patients were women. The mean time of onset of hypertension was 9.1 years. A total of 13.1% of patients (95% confidence interval 12.4-13.6%) had hypotension, 95% of whom had low diastolic blood pressure. The prevalence of hypotension was higher in elderly patients (25.7%) and in those individuals with coronary heart disease (22.6%). The variables associated with the presence of hypotension included a history of cardiovascular disease, being treated with at least 3 antihypertensive drugs, diabetes, and age. CONCLUSIONS: One out of 4-5 elderly patients, or those with cardiovascular disease, had hypotension. General practitioners should identify these patients in order to determine the causes and adjust treatment to avoid complications

OBJETIVO: Determinar la prevalencia de hipotensión y los factores asociados en pacientes hipertensos tratados en atención primaria. MATERIAL Y MÉTODOS: Estudio transversal, descriptivo y multicéntrico; 2.635 médicos generales incluyeron consecutivamente a 12.961 pacientes hipertensos tratados y atendidos en atención primaria en España. Fueron analizados: edad, sexo, peso, altura, índice de masa corporal, perímetro de cintura, factores de riesgo cardiovascular (diabetes, dislipidemia, tabaquismo, obesidad, sedentarismo), glucemia en ayunas, perfil de lípidos, así como la presencia de daño en órgano diana (hipertrofia ventricular, microalbuminuria, aterosclerosis carotídea) y enfermedades clínicas asociadas. La hipotensión se definió como presión arterial sistólica inferior a 110mmHg o presión arterial diastólica inferior a 70mmHg. Se realizó un análisis multivariante para determinar las variables asociadas a la presencia de hipotensión. RESULTADOS: La edad media fue de 66,2 años, un 51,7% de los pacientes eran mujeres. La antigüedad de la hipertensión fue de 9,1 años. Un 13,1% de los pacientes (intervalo de confianza del 95%: 12,4-13,6%) tenían hipotensión, de los cuales el 95% era presión arterial diastólica baja. La prevalencia de hipotensión fue mayor en pacientes de edad avanzada (25,7%) y en individuos con enfermedad coronaria (22,6%). Las variables asociadas con la presencia de hipotensión incluyeron los antecedentes de enfermedad cardiovascular, pacientes tratados con al menos 3 fármacos antihipertensivos, diabetes y edad. CONCLUSIONES: Uno de cada 4-5 pacientes de edad avanzada o con enfermedad cardiovascular tenía hipotensión. Los médicos generales deben identificar a estos pacientes para determinar las causas y ajustar el tratamiento para evitar complicaciones

Genetic Analysis of Agronomic Traits and Grain Iron and Zinc Concentrations in a Doubled Haploid Population of Rice (Oryza sativa L.).

The development of micronutrient dense rice varieties with good agronomic traits is one of the sustainable and cost-effective approaches for reducing malnutrition. Identification of QTLs for high grain Fe and Zn, yield and yield components helps in precise and faster development of high Fe and Zn rice. We carried out a three-season evaluation using IR05F102 x IR69428 derived doubled-haploid population at IRRI. Inclusive composite interval mapping was carried out using SNP markers and Best Linear Unbiased Estimates of the phenotypic traits. A total of 23 QTLs were identified for eight agronomic traits and grain Fe and Zn concentration that explained 7.2 to 22.0% PV. A QTL by environment interaction analysis confirmed the stability of nine QTLs, including two QTLs for Zn on chromosomes 5 and 12. One epistatic interaction for plant height was significant with 28.4% PVE. Moreover, five QTLs were identified for Fe and Zn that harbor several candidate genes, e.g. OsZIP6 on QTL qZn5.1. A number of QTLs were associated with a combination of greater yield and increased grain Zn levels. These results are useful for development of new rice varieties with good agronomic traits and high grain Zn using MAS, and identification of genetic resources with the novel QTLs for grain Zn.

Descripción de la muestra, diseño y métodos del estudio para la identificación de la población española de riesgo cardiovascular y renal (IBERICAN) / Description of the sample, design and methods of the study for the identification of the Spanish population at cardiovascular and renal risk (IBERICAN)

ANTECEDENTES Y OBJETIVO: Las enfermedades cardiovasculares (ECV) son la primera causa de muerte en nuestro país, y aunque las tasas de incidencia disminuyen desde hace años por las mejoras en la prevención y el tratamiento, aún hay margen para una mayor reducción. La atención primaria tiene un papel primordial en la prevención y el control de estas enfermedades. Conocer la prevalencia e incidencia de los factores de riesgo cardiovascular y de las enfermedades cardiovasculares en población adulta española asistida en atención primaria es el objetivo del estudio para la identificación de la población española de riesgo cardiovascular y renal (IBERICAN). MATERIAL Y MÉTODOS: Estudio de cohortes prospectivas. Población asistida en centros de atención primaria entre 18 y 85 años seleccionada mediante muestreo consecutivo no probabilístico entre el 1 de abril de 2014 y el 31 de octubre de 2018. Mediante revisión de la historia clínica, analíticas y visitas médicas el médico del paciente ha recogido información sociodemográfica, antecedentes personales y familiares y prevalencia e incidencia de factores de riesgo cardiovascular y enfermedad cardiovascular y renal. Se estimarán las incidencias y factores asociados mediante modelos de riesgos proporcionales de Cox y curvas de Kaplan-Meier. RESULTADOS: Forman parte de la cohorte IBERICAN 8.066 pacientes reclutados por 531 médicos de atención primaria de todas las CC. AA. de España, con la excepción de Ceuta. La edad media de la cohorte es de 57,9 años, con un 54,5% de mujeres. La obesidad, la dislipidemia y la HTA son los factores de riesgo cardiovascular más prevalentes. El 16,3% presentaba antecedentes de ECV y el 25,5% alguna lesión de órgano subclínica. CONCLUSIÓN: El estudio IBERICAN es una cohorte de personas atendidas en atención primaria que espera aportar información relevante sobre los factores que determinan la incidencia de ECV y renal en España

BACKGROUND AND OBJECTIVE: Cardiovascular diseases (CVD) are the leading cause of death in Spain, and although the incidence rates have been declining for years due to improvements in prevention and treatment, there is still room for further reduction. Primary Care has a leading role in the prevention and control of these diseases. Determining the prevalence and incidence of cardiovascular risk factors and cardiovascular diseases in the Spanish adult population attended in Primary Care is the objective of the study to identify the Spanish population at cardiovascular and renal risk (IBERICAN). MATERIAL AND METHODS: A prospective cohort study was conducted using a consecutive non-probabilistic sampling population between 18 and 85 years that attended Primary Care centres between April 1, 2014 and October 31, 2018. By reviewing the medical history, laboratory results, and medical visits, the Primary Care physicians collected socio-demographic information, personal and family history of the patients, as well as prevalence and incidence of cardiovascular risk factors and cardiovascular and renal disease. The incidents and associated factors will be estimated using proportional risk models of Cox and Kaplan-Meier Curves. RESULTS: A total of 8,066 patients have been recruited by 531 Primary Care physicians from all Autonomous Communities of Spain as part of the IBERICAN cohort, with the exception of Ceuta. The mean age of the cohort is 57.9 years with 54.5% women. Obesity, dyslipidaemia, and hypertension are the most prevalent cardiovascular risk factors. There was a history of CVD in16.3%, and 25.5% had a subclinical organ lesion. CONCLUSION: The IBERICAN study is a cohort of people treated in Primary Care that expects to provide relevant information on the factors that determine the incidence of cardiovascular and renal disease in Spain

Utilización de los anticoagulantes orales de acción directa en Atención Primaria de España. Posicionamiento de SEMERGEN ante la situación actual / Use of direct-acting oral anticoagulants in Primary Care in Spain. Positioning statement by SEMERGEN on the current situation

Los anticoagulantes orales de acción directa (ACOD) son fármacos que han demostrado tener un perfil de seguridad superior a los antivitaminaK (AVK). En España la prescripción de los ACOD está subordinada a un visado de inspección que recoge las condiciones clínicas definidas en el Informe de Posicionamiento Terapéutico (IPT) de la Agencia Española del Medicamento del año 2013, actualizado en 2016. Estas recomendaciones no coinciden con las de la Sociedad Europea de Cardiología (2016), limitando el uso de ACOD a un tratamiento de segunda línea en la mayoría de los casos. Además, el IPT se aplica de manera distinta en las comunidades autónomas e incluso en las áreas sanitarias, lo que origina una gran variabilidad en las condiciones de prescripción, generando desigualdades territoriales en la accesibilidad a estos fármacos por parte de los pacientes. La eliminación del visado y la adecuación de la prescripción a las recomendaciones de las guías de práctica clínica son dos aspectos clave para neutralizar las actuales barreras administrativas y clínicas para el uso eficiente de los ACOD en atención primaria (AP). SEMERGEN apuesta por el refuerzo de la formación clínica del médico de AP y la alianza con los pacientes para promover la concienciación y el conocimiento de la fibrilación auricular

The direct-acting oral anticoagulants (DOACs) are drugs that have been shown to have a safety profile superior to the vitaminK antagonists (VKA). The prescribing of DOACs in Spain is subject to approval in the form of an inspection visa. This sets out the clinical conditions defined in the Spanish Medicines Agency Therapeutic Positioning Report (TPR) of 2013, updated in 2016. These recommendations do not coincide with those of the European Cardiology Society (2016), restricting the use of DOACs to a second-line treatment in the majority of cases. Furthermore, this TPR is applied differently in the Regional Autonomous Communities and even in different health areas. This leads to a wide variation in the prescribing conditions, causing territorial inequalities in accessibility to these drugs by patients. The removal of the visa, and the appropriateness of the prescription to the recommendations of the Clinical Practice guidelines are key aspects to neutralise the current administrative and clinical barriers for the efficient use of DOACs in Primary Care. SEMERGEN supports the boosting of the clinical training and alliance with the patients in order to promote awareness and knowledge of atrial fibrillation

Effect of the vaginal microbiome on the pregnancy rate in women receiving assisted reproductive treatment.

PURPOSE: To investigate if the vaginal microbiome influences the IVF outcome. METHODS: Thirty-one patients undergoing assisted reproductive treatment (ART) with own or donated gametes and with cryotransfer of a single euploid blastocyst were recruited for this cohort study. Two vaginal samples were taken during the embryo transfer procedure, just before transferring the embryo. The V3 V4 region of 16S rRNA was used to analyze the vaginal microbiome, and the bioinformatic analysis was performed using QIIME2, Bioconductor Phyloseq, and MicrobiomeAnalyst packages. Alpha diversity was compared between groups according to the result of the pregnancy test. RESULTS: Fourteen (45.2%) patients did not and seventeen (54.8 %) did achieve pregnancy under ART. A greater index of alpha diversity was found in patients who did not achieve pregnancy comparing to those who did, although this difference was not significant (p = 0.088). In the analysis of beta diversity, no statistically significant differences were observed between groups established as per the pregnancy status. Samples from women who achieved pregnancy showed a greater presence of Lactobacillus spp. The cluster analysis identified two main clusters: the first encompassed the genera Lactobacillus, Gardnerella, Clostridium, Staphylococcus, and Dialister, and the second included all other genera. Women who achieved pregnancy were mainly detected microorganisms from the first cluster. CONCLUSIONS: The vaginal microbiome can influence the results of ART. The profiles dominated by Lactobacillus were associated with the achievement of pregnancy, and there was a relationship between the stability of the vaginal microbiome and the achievement of pregnancy.

Prevalencia de obesidad y comorbilidad cardiovascular asociada en los pacientes incluidos en el estudio IBERICAN (Identificación de la poBlación Española de RIesgo CArdiovascular y reNal) / Prevalence of obesity and cardiovascular comorbidity associated in patients included in the IBERICAN study

OBJETIVOS: Analizar la prevalencia de obesidad y su asociación con otros factores de riesgo cardiovascular y la enfermedad cardiovascular en una muestra de pacientes del estudio IBERICAN. MATERIAL Y MÉTODOS: Análisis de la visita de inclusión de los primeros 5.013 individuos reclutados del estudio IBERICAN, estudio longitudinal, observacional y multicéntrico en el que se están incluyendo individuos de 18 a 85 años en las consultas de Atención Primaria en las diferentes comunidades autónomas de España. En este trabajo se definió la obesidad como índice de masa corporal ≥ 30 kg/m2. RESULTADOS: La prevalencia de obesidad fue del 35,7% (IC 95%: 35,0-36,4%), 36,6% en varones y 34,9% en mujeres (p = 0,214), que se incrementa con la edad de manera significativa (p < 0,001). Los obesos presentaron, respecto a los no obesos, mayor prevalencia de hipertensión arterial (62,8 vs. 39,4%; p < 0,001), dislipidemia (56,9 vs. 47,1%; p < 0,001), sedentarismo (40,6 vs. 24,6%; p < 0,001), diabetes mellitus (27,5 vs. 14,8%; p < 0,001), hiperuricemia (23,6 vs. 12,7%; p < 0,001), lesión subclínica de órgano (33,7 vs. 26,5%; p <0,001) y enfermedad cardiovascular (21,2 vs. 15,3%; p < 0,001). El análisis multivariante mostró que las variables asociadas con la obesidad fueron: hipertensión arterial (p < 0,001), hiperuricemia (p < 0,001), sedentarismo (p < 0,001), diabetes mellitus (p < 0,001), edad (p <0,001), bajo nivel educativo (p < 0,001) y menor consumo de tabaco (p < 0,001). CONCLUSIONES: El análisis del estudio IBERICAN muestra que aproximadamente una tercera parte de la población analizada cumple criterios de obesidad y que los factores de riesgo cardiovascular, lesión en órganos diana y enfermedad cardiovascular eran más frecuentes en los obesos

OBJECTIVES: To analyse the prevalence of obesity and its association with other cardiovascular risk factors and cardiovascular disease in a sample of patients from the (Identification of the Spanish population at cardiovascular and renal risk) IBERICAN study. MATERIAL AND METHODS: Analysis of the inclusion visit of the first 5,013 patients of the IBERICAN longitudinal, observational, and multicentre study in which individuals aged 18 to 85 years were included in Primary Care Clinics in the different regions of Spain. In this work obesity was defined as a body mass index ≥ 30 kg/m2. RESULTS: The prevalence of obesity was 35.7% (95% CI: 35.0-36.4%), of which 36.6% were men and 34.9% were women (P = 0.214), and significantly increasing with age (0.001). The obesity had the associated higher prevalence of hypertension (62.8% vs. 39.4%, P < 001), dyslipidaemia (56.9% vs. 47.1%, P <0.001), sedentary lifestyle (40.6% vs. 24.6%, P <.001), diabetes (27.5% vs. 14.8%, P <.001), hyperuricaemia (23.6% vs. 12.7%, P <.001), subclinical organ injury (33.7% vs. 26.5%, P < .001) and cardiovascular disease (21.2% vs. 15.3%, P <.001). The multivariate analysis showed that the variables associated with obesity were: arterial hypertension (P <.001), hyperuricemia (P < .001), sedentary lifestyle (P < .001), diabetes mellitus (P < 0.001), age (P < 0.001), low educational level (P < 0.001) and lower consumption of tobacco (P < 0.001). CONCLUSIONS: The analysis of the IBERICAN study shows that approximately one third of the analysed population meets criteria of obesity and cardiovascular risk factors. Target organ damage and cardiovascular disease were more frequent in obese patients

Posicionamiento para el manejo de la hipertensión arterial en atención primaria a partir del análisis crítico de las guías americana (2017) y europea (2018). Sociedad Española de Médicos de Atención Primaria (EMERGEN) / Positioning for the management of arterial hypertension in Primary Care from the critical analysis of the American (2017) and European (2018) guidelines. Spanish Society of Primary Care Physicians (SEMERGEN)

Parece necesario que las sociedades científicas de AP, ámbito en el cual la prevalencia de HTA es considerable, evalúen periódicamente las directrices internacionales para el manejo de la HTA, sobre todo ante recomendaciones dispares que dificultan la toma de decisiones, en la práctica clínica diaria. El presente documento tiene como objetivo analizar los cambios y novedades propuestos en la guía del American College of Cardiology y de la American Heart Association (ACC/AHA 2017) y en la guía de la European Society of Cardiology y de la European Society of Hypertension (ESC/ESH 2018). Además, analizar las posibles diferencias, limitaciones y su aplicabilidad a la AP de España. En definitiva, se trata de extraer la información más relevante disponible y pertinente, e integrarla para homogeneizar la asistencia al paciente hipertenso desde una perspectiva crítica, pero también razonada. Las discrepancias entre ambas GPC en aspectos tan trascendentales como el manejo de la enfermedad obligan a la recopilación y análisis crítico de la información que nos permita tomar posición como sociedad científica, interesada en trasladar a todos los médicos de AP las recomendaciones más relevantes, pero a la vez sensatas, de ambas GPC

The Scientific Societies of Primary Care, being the area in which there is a considerable prevalence of Arterial Hypertension (AHT), need to periodically evaluate the international guidelines for its management. This is particularly relevant when disparate guidelines make it difficult to make decisions in daily clinical practice. The present document has as its aim to analyse the changes and new developments proposed in the guidelines of the American College of Cardiology and the American Heart Association (ACC/AHA 2017), as well as in the guidelines of the European Society of Cardiology and European Society of Hypertension (ESC/ESH 2018). An analysis will be made of any differences, limitations, and their applicability to Primary Care in Spain. Finally, the most relevant available and appropriate information is extracted and integrated in order to homogenise the care of the hypertensive patient, from a critical, but also a reasoned, perspective. The discrepancies between the recommendations in such essential aspects as the management of the disease, require the compiling and critical analysis of the information that enables us as scientific society, interested in providing all PC physicians with the most relevant, and at the same time, sensible, recommendations of all the guidelines

Trixis angustifolia hexanic extract displays synergistic antibacterial activity against M. tuberculosis.

A phytochemical and antibacterial study of Trixis angustifolia, a species endemic to Mexico, was performed allowing the isolation of six flavones. The minimal inhibitory concentration (MIC) of the hexanic extract, against Mycobacterium tuberculosis H37Rv was 25 µg/mL. The hexanic extract caused a significant inhibition of intracellular mycobacterial growth at 12.5 µg/mL. The biodirected assay of hexane extract enabled the detection of an active fraction (AF) against M. tuberculosis (MIC = 12.5 µg/mL), and a major flavone 1 (pebrellin) with no antimycobacterial activity (MIC > 200 µg/mL). A subsequent combination antimicrobial assay showed a synergistic antimycobacterial effect of AF in combination with pebrellin; the results of the synergistic activity suggest that the antimycobacterial activity found in T. angustifolia is due to the combined action of diverse metabolites present in the plant.

Genome-Wide Association Mapping in a Rice MAGIC Plus Population Detects QTLs and Genes Useful for Biofortification.

The development of rice genotypes with micronutrient-dense grains and disease resistance is one of the major priorities in rice improvement programs. We conducted Genome-wide association studies (GWAS) using a Multi-parent Advanced Generation Inter-Cross (MAGIC) Plus population to identify QTLs and SNP markers that could potentially be integrated in biofortification and disease resistance breeding. We evaluated 144 MAGIC Plus lines for agronomic and biofortification traits over two locations for two seasons, while disease resistance was screened for one season in the screen house. X-ray fluorescence technology was used to measure grain Fe and Zn concentrations. Genotyping was carried out by genotype by sequencing and a total of 14,242 SNP markers were used in the association analysis. We used Mixed linear model (MLM) with kinship and detected 57 significant genomic regions with a -log10 (P-value) ≥ 3.0. The PH 1.1 and Zn 7.1 were consistently identified in all the four environments, ten QTLs qDF 3.1, qDF 6.2 qDF 9.1 qPH 5.1 qGL 3.1, qGW 3.1, qGW 11.1, and qZn 6.2 were detected in two environments, while two major loci qBLB 11.1 and qBLB 5.1 were identified for Bacterial Leaf Blight (BLB) resistance. The associated SNP markers were found to co-locate with known major genes and QTLs such as OsMADS50 for days to flowering, osGA20ox2 for plant height, and GS3 for grain length. Similarly, Xa4 and xa5 genes were identified for BLB resistance and Pi5(t), Pi28(t), and Pi30(t) genes were identified for Blast resistance. A number of metal homeostasis genes OsMTP6, OsNAS3, OsMT2D, OsVIT1, and OsNRAMP7 were co-located with QTLs for Fe and Zn. The marker-trait relationships from Bayesian network analysis showed consistency with the results of GWAS. A number of promising candidate genes reported in our study can be further validated. We identified several QTLs/genes pyramided lines with high grain Zn and acceptable yield potential, which are a good resource for further evaluation to release as varieties as well as for use in breeding programs.

Outcome of childhood leukaemia survivors and necrosis of the femoral head treated with autologous mesenchymal stem cells

Purpose. Corticoid-induced osteonecrosis (ON) of femoral head can lead to severe hip joint impairment and hip replacement, with negative impact in young survivors of acute lymphoblastic leukaemia (ALL) with long life expectancy. We aim to improve quality of life in these patients with a novel approach. Methods/patients. Based on the regenerative capacities of mesenchymal stem cells (MSCs), we performed locally implanted autologous cell therapy in two adolescents suffering of bilateral femoral ON. This required a simple, minimally invasive surgical procedure. Results. Both patients experienced significant pain relief and restoration of gait kinematic values. Radiographic evaluation showed cessation of hip collapse. No toxicities/complications were observed after a 4-year follow-up. Conclusions. Our preliminary results suggest that autologous MSCs can be considered as a novel treatment for children and young adults with ON after overcoming ALL. It may avoid hip replacement and improve quality of life of leukaemia survivors

Genetic Loci Governing Grain Yield and Root Development under Variable Rice Cultivation Conditions.

Drought is the major abiotic stress to rice grain yield under unpredictable changing climatic scenarios. The widely grown, high yielding but drought susceptible rice varieties need to be improved by unraveling the genomic regions controlling traits enhancing drought tolerance. The present study was conducted with the aim to identify quantitative trait loci (QTLs) for grain yield and root development traits under irrigated non-stress and reproductive-stage drought stress in both lowland and upland situations. A mapping population consisting of 480 lines derived from a cross between Dular (drought-tolerant) and IR64-21 (drought susceptible) was used. QTL analysis revealed three major consistent-effect QTLs for grain yield (qDTY1.1, qDTY1.3 , and qDTY8.1 ) under non-stress and reproductive-stage drought stress conditions, and 2 QTLs for root traits (qRT9.1 for root-growth angle and qRT5.1 for multiple root traits, i.e., seedling-stage root length, root dry weight and crown root number). The genetic locus qDTY1.1 was identified as hotspot for grain yield and yield-related agronomic and root traits. The study identified significant positive correlations among numbers of crown roots and mesocotyl length at the seedling stage and root length and root dry weight at depth at later stages with grain yield and yield-related traits. Under reproductive stage drought stress, the grain yield advantage of the lines with QTLs ranged from 24.1 to 108.9% under upland and 3.0-22.7% under lowland conditions over the lines without QTLs. The lines with QTL combinations qDTY1.3 +qDTY8.1 showed the highest mean grain yield advantage followed by lines having qDTY1.1 +qDTY8.1 and qDTY1.1 +qDTY8.1 +qDTY1.3 , across upland/lowland reproductive-stage drought stress. The identified QTLs for root traits, mesocotyl length, grain yield and yield-related traits can be immediately deployed in marker-assisted breeding to develop drought tolerant high yielding rice varieties.

Mexican consensus on dyspepsia / Consenso mexicano sobre la dispepsiaMexican consensus on dyspepsia

Desde la publicación de las guías de dispepsia 2007 de la Asociación Mexicana de Gastroenterología ha habido avances significativos en el conocimiento de esta enfermedad. Se realizó una revisión sistemática de la literatura en PubMed (01/2007 a 06/2016) con el fin de revisar y actualizar las guías 2007 y proporcionar nuevas recomendaciones basadas en evidencia. Se incluyeron todas las publicaciones en español e inglés, de alta calidad. Se redactaron enunciados que fueron votados utilizando el método Delphi. Se estableció la calidad de la evidencia y la fuerza de las recomendaciones según el sistema GRADE para cada enunciado. Treinta y un enunciados fueron redactados, votados y calificados. Se informan nuevos datos sobre definición, clasificación, epidemiología y fisiopatología. La endoscopia debe realizarse en dispepsia no investigada cuando hay datos de alarma o falla al tratamiento. Las biopsias gástricas y duodenales permiten confirmar infección por Helicobacter pylori y excluir enfermedad celiaca, respectivamente. Establecer una fuerte relación médico-paciente, cambios en la dieta y en el estilo de vida son útiles como medidas iniciales. Los bloqueadores H2, inhibidores de la bomba de protones, procinéticos y fármacos antidepresivos son efectivos. La erradicación de H. pylori puede ser eficaz en algunos pacientes. Con excepción de Iberogast y rikkunshito, las terapias complementarias y alternativas carecen de beneficio. No existe evidencia con respecto a la utilidad de prebióticos, probióticos o terapias psicológicas. Los nuevos enunciados proporcionan directrices basadas en la evidencia actualizada. Se presenta la discusión, el grado y la fuerza de la recomendación de cada uno de ellos.

Abstract Since the publication of the 2007 dyspepsia guidelines of the Asociación Mexicana de Gastroenterología, there have been significant advances in the knowledge of this disease. A systematic search of the literature in PubMed (01/2007 to 06/2016) was carried out to review and update the 2007 guidelines and to provide new evidence-based recommendations. All high-quality articles in Spanish and English were included. Statements were formulated and voted upon using the Delphi method. The level of evidence and strength of recommendation of each statement were established according to the GRADE system. Thirty-one statements were formulated, voted upon, and graded. New definition, classification, epidemiology, and pathophysiology data were provided and include the following information: Endoscopy should be carried out in cases of uninvestigated dyspepsia when there are alarm symptoms or no response to treatment. Gastric and duodenal biopsies can confirm Helicobacter pylori infection and rule out celiac disease, respectively. Establishing a strong doctor-patient relationship, as well as dietary and lifestyle changes, are useful initial measures. H2-blockers, proton-pump inhibitors, prokinetics, and antidepressants are effective pharmacologic therapies. H. pylori eradication may be effective in a subgroup of patients. There is no evidence that complementary and alternative therapies are beneficial, with the exception of Iberogast and rikkunshito, nor is there evidence on the usefulness of prebiotics, probiotics, or psychologic therapies. The new consensus statements on dyspepsia provide guidelines based on up-to-date evidence. A discussion, level of evidence, and strength of recommendation are presented for each statement. © 2017 Asociacion Mexicana de Gastroenterologiia.
