Published: May 2020

El estado nutricional inicial (ENI) y el control de la ganancia de peso (GP) durante la gesta, son de vital importancia, ya que su alteración constituye un factor de riesgo para el desarrollo de complicaciones maternas y fetales a corto, mediano y largo plazo. Los objetivos fueron, valorar el estado nutricional pregestacional y gestacional hasta la doceava semana que presentan las mujeres atendidas en el Centro de Salud N°3 de Loja, estimar su GP por trimestre y establecer la relación del estado nutricional y su GP. El estudio es descriptivo. La muestra fue de 92 gestantes que cumplieron los criterios de inclusión. Los datos se recogieron de las curvas de GP y de Índice de Masa Corporal (IMC) del Ministerio de Salud Pública (MSP) contenidas en las historias clínicas de las embarazadas. Luego de analizar la información se obtuvo, un IMC inicial promedio(X ̃) de 25,28Kg/m2 (±4,25DE), la población se dividió en, 56,5% con ENI normal, 28,3% sobrepeso, 14,1% obesidad y 1,1% infrapeso; la GP al final del tercer trimestre fue normal en 44,6%, menor a lo recomendado en 30,4% y excesiva en 27,2%. Se pudo constatar que no existe diferencia significativa (p>0,05) para la relación entre el ENI y la GP al final de la gestación. En conclusión el IMC inicial no es predictor de la GP final que alcanzará la gestante a término de este proceso y la alteración de esta variable podría estar determinada por otros factores.

Published: May 2020

The synthesis of previously unknown unsaturated aromatic oxyethers was carried out by reaction of chloromethylpropargyl(allyl) ether with phenacyl bromide, with the participation of the chiral catalyst - (+)-benzotetramisole, and their configurations were also established. It was shown the anisotropic effect of the phenyl group in the acid chloride of α-methoxytrifluoromethylphenylacetic acid (MTPA-Cl) on the halogenaryl group. Such effect leads to screening of the latter, and this, in turn, leads to a shift to a strong field and positive values of ∆δR/S, while proton signals of the less bulky group are shifted to a weaker field with a negative value of ∆δR/S. The interaction of chloromethylpropargyl (allyl) ether with phenacylbromide with the participation of the chiral catalyst - (+) - benzotetramisole leads to aromatic allyl and propargyl alcohol monoethers. By the chiral derivative agent (CDA) chloride anhydride- α-trifluoro-methyl-phenyl-acetic acid (MTPA-Cl) the absolute configuration of compounds was determined. Due to comparing the ΔδR/S data in the NMR 1H spectra during such interaction it was found that they converted to diastereomers.

Hops flowers are used to impart highly desirable hoppy aromas in beer. The emergence of craft brewing caused an increase in the popularity of intense hoppy beer determining a breeding trend for new hop flavour varieties that differ in terms of oil contents and compounds. The aim of this work is to examine the relationship between volatile organic compounds (VOCs) and sensory properties in an Italian craft beer brewed with 2 selected Italian wild hop varieties and a commercial one (Cascade) grown in 2 sites with different environmental condition. Since the beer aroma is represented by hop flowers and so they increase incise in the finished product. In this study, 6 beer samples produced by an Italian microbrewery using hop plants were collected and analysed for Volatile Organic Compounds (VOCs) profiles using a PTR-TOF-MS and a sensory evaluation (panel and consumer tests). Multivariate statistical analyses (PCA and CANOCO) showed as “Cascade commercial” sample marks with the highest intensity of taste in comparison to other samples. Results showed low interest for the aromas the hops imparted to the beers produced in relationships to the commercial variety grown and bought. In addition, the grown commercial cascade resulted to be interesting, producing a modified aroma profile when compared to its commercial counterpart. Finally, this study showed an initial contribution to screen other wild genotypes to identify new hops for direct use or breeding with new characteristics that can be used for the production of beer with a modified aroma.

A method for detection and quantitative determination of aflatoxins (AFs) produced by Aspergillus flavus in Pistachia vera seeds (pistachio) using Fourier transform infrared spectroscopy, coupled with Diffuse Reflectance Infrared Fourier Transform Spectroscopy (FTIR-DRIFT) is examined in this study. Greek medicinal and aromatic plant extracts with established bioactivity against A. flavus AFs production were used as treatments on pistachio seeds. Classes were analyzed using discriminate analysis algorithm, and distance values were calculated in Mahalanobis distance units. Strong absorptions were detected in the spectral ranges between 1750 and 1500 cm-1, which were different in contaminated and not contaminated samples. The spectra regions that gave matching values less than 50.00 in absolute difference for AFs in pistachio paste samples were 1705 – 1575 cm-1 and 1350 - 900 cm-1. Also, the high performance of FTIR as analytical tool for quantitative estimation of AFs was emerged by the Partial Least Square (PLS) regression model that found to fit perfectly the actual concentration values (R2=99.99%) in combination with low levels of errors of calibration, validation and prediction along with a minimum and low-cost sample preparation. The developed methodology presents a great potential of a valuable and reliable technique for composition determination, differentiation and evaluation of AFs in food products. We also aimed to reduce sample preparation in the methodology described and to include pistachio and plant extract matrix in classification demonstrating the suitability of FTIR DRIFT spectroscopic methods for direct AFs detection and quantification in biorefineries and industry.
Design choices: Empirical recommendations for designing two-dimensional finger-tracking experiments
Authors: Wirth Robert , Foerster Anna , Kunde Wilfried , Pfister Roland 
Published: May 2020

AbstractThe continuous tracking of mouse or finger movements has become an increasingly popular research method for investigating cognitive and motivational processes such as decision-making, action-planning, and executive functions. In the present paper, we evaluate and discuss how apparently trivial design choices of researchers may impact participants’ behavior and, consequently, a study’s results. We first provide a thorough comparison of mouse- and finger-tracking setups on the basis of a Simon task. We then vary a comprehensive set of design factors, including spatial layout, movement extent, time of stimulus onset, size of the target areas, and hit detection in a finger-tracking variant of this task. We explore the impact of these variations on a broad spectrum of movement parameters that are typically used to describe movement trajectories. Based on our findings, we suggest several recommendations for best practice that avoid some of the pitfalls of the methodology. Keeping these recommendations in mind will allow for informed decisions when planning and conducting future tracking experiments.

Published: May 2020

Summary. Objective: to determine the prognostic value of the factors influencing the outcome of treatment of plantar fasciitis, to develop a system for predicting the results of treatment of plantar fasciitis.
Materials and Methods. Analysis of long-term results of conservative treatment of 145 patients with plantar fasciitis. Clinical, instrumental and statistical (correlation-regression analysis) research methods were used. The factors that influenced the end result of treatment were identified.
Results. The statistically significant influence of age, gender, disease duration up to 6 months, BMI up to 25, the presence of “functional” equinus, pronated foot and history of treatment on the prevalence of positive treatment results were determined. The estimation of the informative nature of the presented factors for the probability of achieving positive results of treatment, the calculation of the prognostic coefficients and their sum were determined. A high prognostic evaluation of a successful treatment outcome should be expected with a total prognosis of +5 to +25; a total estimate of prognostic coefficients from -15 to +5 determines the average probability of positive treatment results; the sum of the prognostic coefficients from -34 to -15 determines the low probability of achieving positive treatment results.
Conclusions. The result of treatment of plantar fasciitis depends on age, sex, duration of the disease up to 6 months, BMI, "functional" equinus, pronated foot, and medical history. The system for predicting treatment outcomes involves the possibility of obtaining high, medium and low probability of a positive result when applying conservative treatment.
