Abstract

Background
The objective of this study was to determine the demographic and clinical features of youth supported by member associations of the Federación Mexicana de Diabetes and the Life for a Child Program (LFAC).

Methods
An analysis of 2017 Annual Clinical Data Sheets of 306 subjects from five Mexican centers was performed.

Results
Type 1 diabetes (T1D) was diagnosed in 292 subjects; 54.6% were female, with six diagnosed aged <6 months (genetic tests not yet conducted). Type 2 diabetes (T2D) or other types were diagnosed in 11 and three subjects, respectively. T1D diagnosis age ranged 0.0–22.6 years with a peak at 8 years. The mean ± standard deviation (SD) diabetes duration was 5.3 ± 3.5 years (range 0.0–21.0 years), with a mean ± SD subject age at check-up of 13.3 ± 4.3 years. Of the T1D subjects, 1.0%, 6.7%, 13.7% and 78.6% were receiving 1, 2, 3 and ≥4 insulin injections/day with a mean ± SD daily dose of 0.92 ± 0.34 U/kg. The median number of blood glucose tests/week was 40. The mean/median hemoglobin A1c (HbA1c) levels for those with duration ≥6 months were 8.7/8.4% (72/68 mmol/mol) and were higher in adolescents vs. children. Elevated body mass index SD, triglycerides (≥150 mg/dL) and non-high-density lipoprotein (HDL)-cholesterol (≥130 mg/dL) were common: 7.6%, 11.0% and 12.7% (n = 288, 218 and 180, respectively). Serum creatinine levels were normal in all tested subjects (n = 194).

Conclusions
Youth with diabetes in less-resourced families in Mexico are achieving reasonable glycemia. Most T1D patients use a basal bolus insulin regimen and test blood glucose several times daily. Some subjects have adverse vascular risk factor profiles. Further attention is needed to prevent chronic complications. Monogenic diabetes is very likely in some youth, and genetic testing is indicated.

Abstract
A series of amino-acid based ionic liquids (Bmim[AA]s) have been synthesized and evaluated as catalysts, in aqueous solution. The results of a kinetic study of the thiol-Michael reaction of L-Cysteine with trans-β-nitrostyrene demonstrated the advantages of using (Bmim[AA]s) as organocatalysts. The benefits include high rate constants; mild reaction conditions; and, a reusable catalyst, which leads to a simple and efficient method for these important kinds of reactions.
Thermal conductivity of unidirectional composites consisting of randomly dispersed glass fibers and temperature-dependent polyethylene matrix
Authors: Lin Wan-Qing , Zhang Yu-Xuan , Wang Hui 
Published: September 2019

Abstract
This extensive study investigated the influence of microstructure on the effective transverse thermal conductivity of unidirectional glass fiber reinforced composites, in which the fibers are randomly dispersed and the thermal conductivity of polyethylene matrix is a function of test temperature. The microstructure is characterized by parameters such as the number of fibers, fiber volume fraction, fiber size, fiber arrangement and thermal property contrast. Firstly, a simple algorithm is developed to automatically generate closest-to-real random array of fibers in unit cell to reconstruct the composite microstructure. Then, the established two-dimensional random two-component composite unit cell is solved using finite element simulation and the obtained effective thermal conductivities are compared with the theoretical predictions and the experimental results. Subsequently, the effects of microstructure parameters and test temperature are investigated, respectively. It is found that the finite element predicted properties are in very good agreement with the experimental predictions, while they are always lower than the analytically predicted properties. These results can find applications in the design of composite materials taking into account the fiber distribution morphology.
On computing the minimum singular value of a tensor sum
Authors: Ohashi A. , Sogabe T. 
Published: September 2019

Abstract
Recently, the Lanczos bidiagonalization method over tensor space has been proposed for computing the maximum and minimum singular values of a tensor sum T. The method over tensor space is practical in memory and has a simple implementation due to recent developments in tensor computations; however, there is still room for improvement in the convergence to the minimum singular value. This study reconstructed an invert Lanczos bidiagonalization method from vector space to tensor space. The resulting algorithm requires solving linear systems at each iteration step. Using standard direct methods, such as the LU decomposition for solving the linear systems requires a huge memory of O(n
6). Therefore, this paper proposes a tensor-structure-preserving direct methods of T whose memory requirements are of O(n
3), which is equivalent to the order of iterative methods. Numerical examples indicate that the number of iterations tends to be much smaller than that of the conventional method.

Reconstruction of multispectral images from spectrally coded light fields of flat scenes
Authors: Schambach Maximilian , Puente León Fernando 
Published: September 2019

Abstract
We present a novel method to reconstruct multispectral images of flat objects from spectrally coded light fields as taken by an unfocused light field camera with a spectrally coded microlens array. In this sense, the spectrally coded light field camera is used as a multispectral snapshot imager, acquiring a multispectral datacube in a single exposure. The multispectral image, corresponding to the light field’s central view, is reconstructed by shifting the spectrally coded subapertures onto the central view according to their respective disparity. We assume that the disparity of the scene is approximately constant and non-zero. Since the spectral mask is identical for all subapertures, the missing spectral data of the central view will be filled up from the shifted spectrally coded subapertures. We investigate the reconstruction quality for different spectral masks and camera parameter sets optimized for real life applications such as in-line production monitoring for which the constant disparity constraint naturally holds. For synthesized reference scenes, using 16 color channels, we achieve a reconstruction

Abstract
We present a massive investigation into the genetic basis of human lifespan. Beginning with a genome-wide association (GWA) study using a de-identified snapshot of the unique AncestryDNA database – more than 300,000 genotyped individuals linked to pedigrees of over 400,000,000 people – we mapped six genome-wide significant loci associated with parental lifespan. We compared these results to a GWA analysis of the traditional lifespan proxy trait, age, and found only one locus, APOE, to be associated with both age and lifespan. By combining the AncestryDNA results with those of an independent UK Biobank dataset, we conducted a meta-analysis of more than 650,000 individuals and identified fifteen parental lifespan-associated loci. Beyond just those significant loci, our genome-wide set of polymorphisms accounts for up to 8% of the variance in human lifespan; this value represents a large fraction of the heritability estimated from phenotypic correlations between relatives.

Published: September 2019

Objetivo Describir la experiencia de enfermeros/as de la Atención Primaria de la ciudad de Viña del Mar, al participar en el Modelo de Atención Integral, para analizar fortalezas y debilidades, desde la mirada del profesional.Método Estudio cualitativo–descriptivo, cuya muestra teórica estuvo conformada por 10 enfermeros/as de la Atención Primaria. Se aplicaron grupos focales y entrevistas semiestructuradas. Se realizó análisis de contenido.Resultados En el contexto del Modelo de Atención Integral se describió a un profesional de enfermería como competente, que además establece vínculos de ayuda con las familias, lo que le hace sentirse satisfecho de su trabajo; sin embargo, se demostró que el déficit de este tipo de profesional constituye un obstáculo para el desempeño en los espacios territoriales de la comunidad. Se evidenció que el Modelo de Salud aún se sitúa en un nivel teórico más que práctico, en que el rol asistencial y el cumplimiento de metas están por sobre las actividades de promoción y prevención.Conclusiones Una mayor dotación del profesional de enfermería en la Atención Primaria de Salud, permitirá contar con un equipo más amplio de especialistas en temas de promoción y prevención, sin debilitar su rol asistencial. El trabajo intersectorial es una necesidad que deberá arraigarse en las entidades comunitarias, requiriendo fortalecer la labor conjunta entre las autoridades de los centros de atención y los representantes comunitarios, a modo de apoyar el quehacer del equipo de salud.

Authors: Másmela-Mendoza Julian Esteban 
Published: September 2019

Introducción. Las especies de Moniliophthora spp. son endémicas de Sudamérica e infectan los cultivos de cacao de América. Objetivo. El objetivo del estudio fue analizar la distribución potencial y el nicho fundamental de Moniliophthora roreri (Mr) y M. perniciosa (Mp) en América y África. Materiales y métodos. Los registros de ocurrencia fueron obtenidos de una revisión bibliográfica. Se utilizaron variables bioclimáticas como predictores en el modelo de nicho de máxima entropía (MaxEnt) y para su visualización en Niche Analyst 3.0. Resultados. Las zonas donde se registró mayor probabilidad de ocurrencia de Mr fueron Esmeraldas y Los Ríos, Ecuador, zonas costeras de Costa Rica, Santander y Antioquia de Colombia, y para Mp los Estados de Bahía y Acré de Brasil. Las variables que más influyeron en la distribución de Mr están asociadas a las precipitaciones. Las condiciones relacionadas con la temperatura fueron más importantes en el modelo de Mp. Se identificó el riesgo de invasión de Mr en las regiones de Acré y Pará, Brasil. La transferencia de los modelos evidenció el potencial de invasión de Mr y Mp en los cultivos de cacao en África. El nicho fundamental de los patógenos y el cacao presentó valores de similitud medios, mientras que, el nicho de las especies de hongos mostró una baja similitud. La baja similitud de los nichos de los patógenos y las diferencias en las variables bioclimáticas que afectan su distribución se podrían relacionar a un proceso de partición del nicho. Conclusión. Se identificaron las regiones geográficas con una mayor distribución potencial de los patógenos y las características bioclimáticas que favorecerían su probabilidad de presencia en los cultivos de cacao de América. Es necesario regular el transporte de material vegetal y equipo contaminado entre regiones para evitar la introducción de los patógenos en cultivos de cacao sanos.

Authors: Toledo-Perdomo Claudia Elizabeth 
Published: September 2019

Introducción. Trialeurodes vaporariorum (Westwood) es una de las principales plagas del ejote francés (Phaseolus vulgaris L.), leguminosa para consumo en vainas inmaduras, y es vector del virus del mosaico dorado, que afecta la calidad y rendimiento del cultivo, con pérdidas hasta del 100%. Su control es poco efectivo, debido a que muchos productos químicos ya no controlan la plaga. El ejote francés dentro de los productos no tradicionales en Guatemala, ocupa el segundo lugar en la exportación. Asegurar un buen manejo fitosanitario con baja carga química por plaguicidas, son factores importantes para poder exportarlo. Objetivo. La investigación tuvo por objetivo determinar la efectividad de la combinación entre flupyradifurone y Beauveria bassiana para el control de la mosca blanca en el cultivo del ejote francés. Materiales y métodos. El estudio se realizó de febrero a diciembre de 2018 en Parramos, Chimaltenango, Guatemala. Se establecieron siete parcelas de 100 m², correspondientes a cada tratamiento. Se muestrearon moscas blancas semanalmente durante dos ciclos de cultivo, también se colectaron en cada parcela enemigos naturales de estas. Se realizaron tres aplicaciones de cada tratamiento en cada ciclo del cultivo y se muestrearon las plantas divididas en tres estratos (alto, medio, bajo). Resultados. Los tratamientos que presentaron el mejor control de la población de mosca blanca (ninfas y adultos) al realizar la prueba de Tukey (0,05), fueron flupyradifurone (1 l ha-1) + B. bassiana y flupyradifurone (0,75 l ha-1) + B. bassiana. La mayor distribución de las poblaciones de mosca blanca se encontró en los estratos alto y medio. Conclusión. La combinación de flupyradifurone (0,75 l ha-1) con B. bassiana puede ser empleado dentro de un manejo integrado de plagas, y se presenta como una alternativa de control de la mosca blanca, que ha adquirido resistencia a algunos agroquímicos.

Abstract
This study sought to evaluate attitudes and knowledge about prenatal yoga and to investigate barriers and facilitators to yoga participation in high-risk pregnant women receiving prenatal care in an academic tertiary care center. We surveyed a convenience sample of women receiving prenatal care through the Maternal-Fetal Medicine practice at Brigham and Women’s Hospital. We classified participants as yoga-experienced or yoga-naive depending on self-report. We compared differences between the two groups using the appropriate nonparametric tests and compared bivariate odds ratios for survey results using logistic regression. Of the 100 respondents, 53% had practiced yoga previously. Women with yoga experience were older (age 34.9 ± 5.6 vs. 31.0 ± 6.0 years, p = 0.004), more likely to be college graduates (94% vs. 68%, p = 0.002), and more likely to be White (77% vs. 47%, p = 0.002) than women without previous yoga experience. Previous yoga experience was associated with participant agreement that yoga was safe during their current pregnancy (odds ratio 5.9, 95% confidence interval 1.9–17.7). Of the women surveyed, 56% agreed that they would like to attend a prenatal yoga class. In a multivariate model including age, race, and education, previous yoga experience was the only significant predictor associated with willingness to participate in prenatal yoga classes during current pregnancy (odds ratio 3.1, 95% confidence interval 1.1–8.6). Prior yoga experience was the strongest predictor of willingness to attend a prenatal yoga class in our population. Our results suggest that women with high-risk pregnancies who may benefit from prenatal yoga interventions but lack prior yoga experience may need additional education to facilitate participation.

In this study, we first tried to determine whether the expression level of 9 miRNAs in the peripheral blood CD8+ T cells of asthmatic patients varies from that of controls, and secondly, we investigated the effects of fluticasone furoate and vilanterol on the expression level of these miRNAs.
Fifteen subjects including 8 healthy individuals and 7 asthmatic patients were included in this study. CD8+T cells were isolated from participants' peripheral blood by a negative selection method using magnetic-activated cell sorting (MACS). The expression of 9 miRNAs was examined between the healthy individuals and asthmatic patients. Then the expression level of 9 miRNAs before and after treatment with the drugs was examined by quantitative real-time PCR.
No significant changes in the expression level of 9 miRNAs were observed in asthmatic patients compared to the healthy controls. Fluticasone and vilanterol, in combination, had the greatest effect on miRNA expression. MiR-150 and miR-106a were the most and the least miRNAs, respectively, present in CD8+ T cells of patients and controls. MiR-106a and miR-126 had a positive correlation in CD8+ cells of asthmatic patients.
Although no significant difference in the expression level of studies miRNAs was observed, the correlations among miRNAs were significant. Therefore, we suggest that the correlation between miRNAs would be a very important factor in physiological and pathological conditions in healthy individuals and asthmatic patients. Such a miRNA-miRNA correlation network can be even more critical than any changes in the variation of their expression in the CD8+ T cells.

Published: September 2019

Background: Hospital, as one of the most important organizations for health promotion, requires efficient and effective human resources. Health information management staffs are responsible for storing, processing, and distributing information used to improve the quality of healthcare services. This study aimed to investigate the relationship between quality of work-life and productivity of health information management staff.
Methods: This descriptive analytical cross-sectional study was conducted on 165 staffs of health information management department in an educational hospital of Isfahan in 2017. The data were collected using Walton Work Quality life Questionnaire and Gold Smith's Manpower Productivity Questionnaire. Data were analyzed using descriptive and analytical statistics, including Pearson correlation coefficient, independent t-test, Spearman correlation coefficient, analysis of variance and linear regression analysis by SPSS 18.
Results: Average scores for the quality of work life and productivity were 2.65 ± 0.51 and 2.64 ± 0.42, respectively. According to one-sample t-test, these scores had a significant difference with the moderate level (p < 0.05). Based on the Pearson correlation test, the quality of work life had a direct and significant relationship with the productivity of staff (r = 0.73 and p < 0.05). Independent t-test showed that the average score of productivity in men was significantly higher than women (p < 0.05).
Conclusion: Considering the direct and significant relationship between the quality of work life and productivity in the staff of health information management department as well as the low level of these two components, the relevant authorities should take appropriate measures. These approaches include safe physical design of workspace and establishment of a fair payment system in accordance with the working conditions of this department. The quality of work life should be improved since it affects the quality of service delivery and staff productivity.
