ABSTRACT

There is currently a limited understanding of the complex response of fungal microbiota diversity to organic fertigation. In this work, a 2-year field trial with organic tomato crops in a soil previously amended with fresh sheep manure was conducted. Two hypotheses were compared: (i) fertigation with organic liquid fertilizers versus (ii) irrigation with water. At the end of both years, soils were analyzed for physical-chemical parameters and mycobiome variables. Plate culture and DNA metabarcoding methods were performed in order to obtain a detailed understanding of soil fungal communities. Fertigation did not increase any of the physical-chemical parameters. Concerning soil fungal communities, differences were only found regarding the identification of biomarkers. The class Leotiomycetes and the family Myxotrichaceae were identified as biomarkers in the soil fungal community analyzed by means of DNA metabarcoding of the "fertigation" treatment at the end of Year 1. The Mortierella genus was detected as a biomarker in the "water" treatment, and Mucor was identified in the "fertigation" treatment in the cultivable soil fungi at the end of Year 2. In both years, tomato yield and fruit quality did not consistently differ between treatments, despite the high cost of the fertilizers added through fertigation.

ABSTRACT

Pisum sativum L. ssp. arvense, is colloquially called tirabeque or mangetout because it is eaten whole; its pods are recognized as a delicatessen in cooking due to its crunch on the palate and high sweetness. Furthermore, this legume is an important source of protein and antioxidant compounds. Quality control in this species requires the analysis of a large number of samples using costly and laborious conventional methods. For this reason, a non-chemical and rapid technique as near-infrared reflectance spectroscopy (NIRS) was explored to determine its physicochemical quality (color, firmness, total soluble solids, pH, total polyphenols, ascorbic acid and protein content). Pod samples from different cultivars and grown under different fertigation treatments were added to the NIRS analysis to increase spectral and chemical variability in the calibration set. Modified partial least squares regression was used for obtaining the calibration models of these parameters. The coefficients of determination in the external validation ranged from 0.50 to 0.88. The RPD (standard deviation to standard error of prediction ratio) and RER (standard deviation to range) were variable for quality parameters and showed values that were characteristic of equations suitable for quantitative prediction and screening purposes, except for the total soluble solid calibration model.

ABSTRACT

OBJETIVO: Evaluar la asociación de la presión diastólica (PAD) y variables metabólicas en embarazadas. METODOLOGÍA: Estudio retrospectivo, transversal en embarazadas de término, mayores de 25 años, con embarazo único, agrupadas por Índice de Masa Corporal (IMC). A todas se les midieron lípidos, glucosa y PAD. Se calculó Odds Ratio (IC 95 %), correlación de Spearman entre variables y Kruskal Wallis utilizando SPSS v21.0. RESULTADOS: Se incluyeron 60 embarazadas normoevolutivas, edad promedio 30.9 ± 4.5 años, obteniendo una prevalencia de 41.6 % para sobrepeso y 31.6 % para obesidad. Los valores de glucemia en ayuno fueron de 102.2 ± 49.8 mg/dL en obesidad, 89.8 ± 28.7 mg/dL en sobrepeso y 84.5 ± 12.3 mg/dL en normopeso. Los valores medios de la PAD y PAS mostraron una correlación positiva con el valor medio de IMC pregestacional y gestacional. Mientras que, para las concentraciones de glucosa y lípidos, se obtuvo una correlación positiva con el valor medio de la PAD. CONCLUSIÓN: Se confirma asociación de la PAD con el IMC pregestacional.

OBJECTIVE: To evaluate the association of diastolic pressure (DBP) and metabolic variables in pregnant women. METHODOLOGY: Retrospective, cross-sectional study in full-term pregnant women, older than 25 years, with a single pregnancy, grouped by Body Mass Index (BMI). Lipids, glucose and DBP were measured in all of them. Odds Ratio (95% CI), Spearman's correlation between variables and Kruskal Wallis were calculated using SPSS v21.0. RESULTS: 60 normodevelopmental pregnant women were included, mean age 30.9 ± 4.5 years, obtaining a prevalence of 41.6% for overweight and 31.6% for obesity. Fasting blood glucose values ​​were 102.2 ± 49.8 mg / dL in obesity, 89.8 ± 28.7 mg / dL in overweight, and 84.5 ± 12.3 mg / dL in normal weight. The following ORs were obtained for DBP> 80 mmHg with SBP> 130 mmHg (1,571; 95% CI: 0.490-5.037), glucose> 90 mg/dL (1.052; 95% CI: 0.451-2.453), cholesterol > 200 mg / dL (1.667; 95% CI: 0.694-4.004), triglycerides> 150 mg/dL (1.2; 95% CI: 0.243-1.832), platelets <150 thousand / µL (1.072; 95% CI: 0.220-2.974) and lymphocytes <1000 /µL (1.145; 95% CI: 0.168-2.405). CONCLUSION: The association of DBP disorders with pre-pregnancy BMI is confirmed. (provided by Infomedic Intl)

ABSTRACT

Introduction: Continuous home oxygen therapy (CHOT), along with smoking cessation, is the first treatment that has been shown to increase the survival of patients with chronic obstructive pulmonary disease (COPD) and chronic hypoxemia. Objective: To determine survival in a cohort of COPD patients receiving CHOT and to analyze the main causes and risk factors associated with their mortality. Methods: Prospective study of a cohort of COPD patients receiving CHOT. Numerous variables, including survival and cause of death at the end of follow-up, were collected. Results: A total of 409 COPD patients receiving CHOT were included (85.6% men; mean age: 71.27 ± 9.74 years). Mean time of CHOT follow-up was 5.86 ± 3.24 years and median survival was 6 years (95% CI: 5.47-6.53). Mortality at the end of follow-up was 75.8%, the leading cause of death being respiratory (36.9%). Longer survival was significantly associated with lower age, correct CHOT compliance, absence of exacerbations in the previous year, use of long-acting anticholinergics (LAMA), less severe COPD, presence of sleep apnea-hypopnea syndrome/obesity hypoventilation syndrome (SAHS/SHO), absence of malignant disease, heart disease, cerebrovascular disease, and kidney disease. Conclusions: The survival of COPD patients receiving CHOT was very long. The main causes of mortality were respiratory (36.9%). Independent predictors of mortality were age, presence of exacerbations in the previous year, previous diagnosis of cancer, and presence of cerebrovascular and renal disease.

ABSTRACT

A rapid method to quantify the total phenolic content (TPC) and total carotenoid content (TCC) in blackberries using near infrared spectroscopy (NIRS) was carried out aiming to provide reductions in analysis time and cost for the food industry. A total of 106 samples were analysed using the Folin-Ciocalteu method for TPC and a method based on Ultraviolet-Visible Spectrometer for TCC. The average contents found for TPC and TCC were 24.27 mg·g-1 dw and 8.30 µg·g-1 dw, respectively. Modified partial least squares (MPLS) regression was used for obtaining the calibration models of these compounds. The RPD (ratio of the standard deviation of the reference data to the standard error of prediction (SEP)) values from external validation for both TPC and TCC were between 1.5 < RPDp < 2.5 and RER values (ratio of the range in the reference data to SEP) were 5.92 for TPC and 8.63 for TCC. These values showed that both equations were suitable for screening purposes. MPLS loading plots showed a high contribution of sugars, chlorophyll, lipids and cellulose in the modelling of prediction equations.

ABSTRACT

Around 27,000 people were killed in the province of Asturias during the Spanish Civil War, with several thousands killed after the war ended. There are currently over 2,000 known mass burial locations throughout Spain, but many more are unknown. Geophysics is a useful tool employed to help in the active attempts to document and improve knowledge about victims from this conflict. This paper details a non-invasive study of the Cementerio de El Salvador, in the city of Oviedo, Northern Spain. Part of the cemetery contains a known mass burial with approximately 1,300 individuals from the Spanish Civil War and post-war repression eras. Multi-frequency near-surface geophysical techniques were undertaken, after permission, to enhance knowledge about which, if any, techniques should be used to detect, delineate and analyse such mass graves. Multi-frequency (250MHz and 500MHz) ground-penetrating radar surveys were acquired together with 2D and 3D Electrical Resistivity Tomography datasets. The results have established the limits of the mass grave and improve the knowledge of the internal mass grave structure. The paper also shows the importance of considering the climatic conditions during data acquisition. This has important implications for the successful detection of recent historical mass burials using near-surface geophysics.

ABSTRACT

Resumen La parálisis diafragmática bilateral es infrecuente y puede ser idiopática o más comúnmente asociada a varias entidades. Describimos el caso de un varón de 61 años con antecedentes de asma bronquial quien desarrolló parálisis difragmática bilateral sin causa evidente, la cual es excepcional. El paciente presentó disnea progresiva y ortopnea, que no mejoraban con antibioterapia ni esteroides sistémicos, por lo que se descartaron diversas etiologías como neuralgia lateral amiotrófica y finalmente se le diagnosticó parálisis diafragmática lateral en base a la exploración física y las pruebas de imagen. Se inició ventilación mecánica no invasiva con gran mejoría clínica.


Bilateral paralysis of the diaphragm is uncommon and can be either idiopathic or more frequently associated with several medical conditions. We describe the case of a 61-year-old man with a history of asthma who developed severe bilateral diaphragmatic paralysis without any obvius cause, which is exceptional. The patient manifested progressive dyspnea and debilitating orthopnea with no improvement with antibiotics or systemic steroids. Different etiologies were discarded as amyotrophic lateral neuralgia, and he was diagnosed of bilateral diaphragmatic paralysis based on physical examination and imaging tests. Noninvasive mechanical ventilation was started with great clinical improvement.

ABSTRACT

La neuralgia amiotrófica es una neuropatía infrecuente caracterizada por la aparición de un dolor intenso unilateral en el hombro. Es rara la afectación aislada o concomitante de otros nervios motores periféricos derivados del plexo cervicobraquial, como el nervio frénico o el laríngeo. Su etiología es desconocida, aunque se han planteado varios factores que pueden condicionar su aparición. La afectación del nervio frénico, unilateral o bilateral, es aún más infrecuente. El diagnóstico se basa en la historia clínica, la exploración funcional, técnicas de imagen y en los hallazgos del electromiograma. Presentamos el caso de una mujer de 48 años con antecedentes de trasplante renal por glomerulonefritis proliferativa y rechazo posterior del mismo, que fue definitivamente diagnosticada de neuralgia amiotrófica con afectación frénica bilateral, que precisó ventilación mecánica no invasiva de forma prolongada (AU)


Amyotrophic neuralgia is an uncommon neuropathy characterized by severe unilateral shoulder pain. Isolated or concomitant involvement of other peripheral motor nerves depending on the brachial plexus such as phrenic or laryngeal nerves is unusual. Its etiology is unknown, yet several explanatory factors have been proposed. Phrenic nerve involvement, either unilateral or bilateral, is exceedingly rare. Diagnosis relies on anamnesis, functional and imaging investigations and electromyogram. We report the case of a 48-year-old woman with a past history of renal transplantation due to proliferative glomerulonephritis with subsequent transplant rejection, who was eventually diagnosed with amyotrophic neuralgia with bilateral phrenic involvement, and who required sustained non-invasive mechanical ventilation (AU)
