To report our experience in maternal-fetal outcome in women with RA in a national medical referral center.
A retrospective analysis of the records of pregnant women with rheumatoid arthritis ...attending at a Pregnancy and Autoimmune Rheumatic Diseases Clinic was performed. Maternal-fetal outcomes such as disease activity, preclampsia/eclampsia, rate of live births, abortions, stillbirths, preterm birth, weeks of gestation, birth weight, congenital malformations and use of anti-rheumatic drugs were studied.
We included 73 pregnancies in 72 patients. Disease activity was documented in 47.2% of patients during pregnancy and/or postpartum and 87.7% of patients received some antirheumatic drug. Preclampsia developed in 8.2% of cases. The live birth rate was 98.6%, with preterm delivery in 15.9% and low weight at term in 17.6% of cases. Cesarean section was performed in 77.1% of cases. The disease activity was not associated with a higher percentage of maternal-fetal complications.
Our study showed that most patients do not experience significant activity of RA during pregnancy, fetal outcome is satisfactory and disease activity did not appear to influence significantly the obstetric outcome.
Ventricular Late Potentials make QRS complexes larger, that is why many algorithms are based on quantifying increases in the QRS complex duration. These elongations generate misalignments in the QRS, ...resulting in practice; the averaged algorithm considers the ECG components, including those VLPs, as well as random variables. We recorded High Resolution ECGs (HRECGs) from 50 subjects in resting position with no heart-stroke antecedents. VLPs were simulated added to the HRECGs, and then two cases were evaluated: (1) duration of the QRS complexes with VLPs without QRS-alignment, and (2) duration of QRS complexes with VLPs using time- and amplitude- QRS-alignment. When using amplitude- and time-alignment it is possible to reach a sensitivity of 0.96 and a specificity of 0.52, as opposed to 0.72 and 0.40, respectively, when using only SAECG without QRS-alignment.
Ventricular Late Potentials (VLPs) are important indicators of sudden cardiac death (SCD) in people with a history of heart attack. Many algorithms for VLPs detection are based on quantifying ...increases in the QRS complex duration due to VLPs make QRS complexes larger. We took High Resolution ECGs from 50 individuals in resting position with no heart-attack antecedents and we simulated a VLPs database according to the American Heart association and the European Society of Cardiology. Two cases were evaluated: the QRS duration of complexes with VLPs simulated without QRS-alignment and QRS duration with VLPs using time and amplitude QRS-alignment prior application of Signal Averaging Electrocardiography (SAECG). Considering QRS duration as an indicative of VLPs presence, results show that using amplitude and time alignment it is possible to reach a sensitivity of 0.96 and a specificity of 0.3, as opposed to 0.72 and 0.40, respectively, using only SAECG.
to identify subjects with impaired fasting glucose (IFG), from a group of apparently healthy individuals.
a cross-sectional study was undertaken in 1188 blood donors, with no family history of ...diabetes (T2D). All these individuals were subjected to a questionnaire, and biochemical tests.
the prevalence of IFG was 15.9 %, 17.1 % in men and 12.9 % in women. The average blood glucose levels in subjects with IFG were 107.2 + or - 6.5 mg/dL in men and 106.0 + or - 6.1 mg/dL in women. Sixty percent of individuals with IFG showed insulin resistance. The diagnosis of metabolic syndrome (MS) in IFG subjects was 20.2 %, according to the NCEP/ATP III criteria, 21.4 % according to the International Diabetes Federation criteria; and 29.3 % according to the American Heart Association and the National Heart, Lung and Blood Institute criteria. Seventy percent of the subjects with IFG showed hypertriglyceridemia, 51 % showed hypercholesterolemia and 85 % were over-weight or obese.
the prevalence of IFG was higher than expected, comparing with other populations reported in the literature. These apparently healthy subjects were not previously diagnosed and therefore have not received preventive actions to arrest the risk of T2D.
A test system based on the Modulation Transfer Function (MTF) was developed to measure the quality of the image capture in digital cameras. This method helps to describe image capture performance ...parameters, as linearity and spatial resolution. The system is composed of an illumination module, a multifrequency sine target, a two axis mechanical support for the digital camera, a three-axis and angular motion support for the sine target, and data processing software. The software was developed under MATLAB for the MTF determination, calculating image contrast at various spatial frequencies. Results are presented for the tests run on three digital cameras: Pentax Optio 450, Sony DSCP41 and Sony DSC-F717.

En este trabajo se presenta un panorama de la situación de la truficultura en España, desde sus comienzos en los años 50 a la actualidad, y sus perspectivas de futuro. Se destaca la actividad ...científica y técnica muy amplia, con numerosas iniciativas de investigación y experimentales desarrolladas en Centros de Investigación y Universidades españolas, que contemplan aspectos tan diversos como micorrización en vivero, certificación de planta micorrizada, ecología de la trufa, recuperación cíe truferas naturales, cultivo y seguimiento de plantaciones truferas, taxonomía química, control de las especies de trufa, reforestación y selvicultura trufera. La situación actual es fruto de investigaciones y trabajos, pioneros en España, de personas y entidades que vieron en la truficultura las posibilidades que la confirman, en este momento, como una actividad con alto interés económico, social y ecológico, a potenciar en áreas con escasas oportunidades agronómicas y forestales de carácter tradicional y que se enmarca, por lo tanto, en el concepto de desarrollo sostenible. Se aportan datos de producciones, precios, áreas de recogida, mercados y comercios, publicaciones, plantaciones truferas y actividad investigadora. Finalmente, se realiza un breve resumen de las perspectivas de futuro del sector trufero en España con el objetivo de establecer líneas o criterios comunes para dicha actividad.
Background: 24-hour movement behaviors, including moderate-to-vigorous physical activity (MVPA), sedentary time (ST), and sleep duration, have important implications for health across the lifespan. ...However, no studies exist that have examined the integration of these 24-hour movement behaviors in Latin America. The purpose of this study was to examine the prevalence of meeting the Canadian 24-Hour Movement Guideline recommendations and sociodemographic correlates of meeting the guidelines in adults from eight Latin American countries. Methods: This was a multi-national cross-sectional study of 2338 adults aged 18 to 64 years from the Latin American Study of Nutrition and Health. MVPA and ST data were collected using accelerometers. Sleep duration was self-reported using a daily log. Socio-demographic correlates included sex, age, education level, and marital status. Meeting the 24-hour movement guidelines was defined as: ≥150 min/week of MVPA; ≤8 h/day of ST; and between 7 and 9 h/day of sleep. Logistic regression models were estimated on pooled data. Results: The prevalence of adults who met the MVPA, ST, sleep duration, and integrated recommendations was 48.3, 22.0, 19.4, and 1.6%, respectively. Overall, being a woman (OR: 0.72; 95%CI: 0.55,0.93) and having a middle (0.63; 0.47,0.85) or high education level (0.31; 0.17,0.56) was associated with lower odds of meeting all three of the 24-hour movement guideline recommendations. Being married (1.70; 1.25,2.29) was associated with greater odds of meeting all three recommendations. Being a woman (0.46; 0.39,0.55), aged 50-64 years (0.77; 0.60,0.97), and married (0.79; 0.65,0.96) were associated with lower odds of meeting the MVPA recommendation. Having a middle (0.64; 0.50,0.80) or high (0.36; 0.23,0.55) education level was associated with lower odds and being married (1.86; 1.46,2.36) was associated with greater odds of meeting the ST recommendation. Being a woman (0.63; 0.51,0.78) was associated with lower odds; whereas being aged 50-64 years (1.40; 1.04,1.88) and having a middle education level (1.37; 1.09,1.73) were associated with greater odds of meeting the sleep duration recommendation. Conclusions: Overall, the proportion of Latin American adults achieving healthy levels of 24-hour movement behaviors was low. Further efforts are needed to promote more MVPA, less ST, and sufficient sleep in Latin American adults. Trial registration: Clinical Trials NCT02226627. Retrospectively registered on August 27, 2014.

Corn is one of the most important cereals for the nutrition of large groups of the Latin American population and arepa is a very popular corn-based food preparation. In order to study the arepa ...consumption effects on glucose and insulin response when β-glucans were added to this preparation, three different meals (white bread, corn flour arepa and arepa with β-glucans were served as breakfast to fourteen young subjects in random order after an overnight fast, to determine basal and postprandial glucose and insulin levels. One way ANOVA test was carry out to compare glucose and insulin responses between test meals and between basal and postprandial (glucose and Insulin) levels of each meal. Ingestion of white bread and corn arepa increased postprandial insulin 70,1 % and 51.8% respectively, but β-glucan arepa increased only 16% postprandial insulin levels, neither white bread and corn arepa nor β-glucan arepa increased significantly postprandial plasma glucose. In conclusion this study shows that by addition of β-glucan, to corn products like arepa reduces glucose and insulin response.
