RESUMEN

The combined impact of high-hydrostatic pressure (HHP) and ultrasound (US) on the cyanidin-3-O-rutinoside (C3R), quercetin-3-O-rutinoside (Q3R), and volatile compounds from fig (Ficus carica) paste was investigated. The HHP increased the content of C3R and Q3R, from 70 to 133 mg/kg fw and 31 to 44 mg/kg fw, respectively. The combination of HHP and US further enhanced the extraction of these bioactive compounds. Specifically, processing fig paste with US for 5 min at 40 °C yielded approximately 250 mg of C3R/kg fw and 45 mg of Q3R/kg fw, after 20 min. More than 25 volatile compounds were identified, with benzaldehyde being the predominant compound, accounting > 75%. Trace amounts of hydroxymethylfurfural (< 0.36 mg/100 g fw) were detected in HHP-processed fig paste. The application of HHP at mild temperatures and short time, combined with US, effectively promotes the content of bioactive compounds present in fig paste without adversely affecting the fruit's volatile compounds.

RESUMEN

Objective. To report the use of a portable primary standard level graphite calorimeter for direct dose determination in clinical pencil beam scanning proton beams, which forms part of the recommendations of the proposed Institute of Physics and Engineering in Medicine (IPEM) Code of Practice (CoP) for proton therapy dosimetry.Approach. The primary standard proton calorimeter (PSPC) was developed at the National Physical Laboratory (NPL) and measurements were performed at four clinical proton therapy facilities that use pencil beam scanning for beam delivery. Correction factors for the presence of impurities and vacuum gaps were calculated and applied, as well as dose conversion factors to obtain dose to water. Measurements were performed in the middle of 10 × 10 × 10 cm3homogeneous dose volumes, centred at 10.0, 15.0 and 25.0 g·cm-2depth in water. The absorbed dose to water determined with the calorimeter was compared to the dose obtained using PTW Roos-type ionisation chambers calibrated in terms of absorbed dose to water in60Co applying the recommendations in the IAEA TRS-398 CoP.Main results.The relative dose difference between the two protocols varied between 0.4% and 2.1% depending on the facility. The reported overall uncertainty in the determination of absorbed dose to water using the calorimeter is 0.9% (k= 1), which corresponds to a significant reduction of uncertainty in comparison with the TRS-398 CoP (currently with an uncertainty equal or larger than 2.0% (k= 1) for proton beams).Significance. The establishment of a purpose-built primary standard and associated CoP will considerably reduce the uncertainty of the absorbed dose to water determination and ensure improved accuracy and consistency in the dose delivered to patients treated with proton therapy and bring proton reference dosimetry uncertainty in line with megavoltage photon radiotherapy.

RESUMEN

BACKGROUND: Mesophotic coral communities are increasingly gaining attention for the unique biological diversity they host, exemplified by the numerous mesophotic fish species that continue to be discovered. In contrast, many of the photosynthetic scleractinian corals observed at mesophotic depths are assumed to be depth-generalists, with very few species characterised as mesophotic-specialists. This presumed lack of a specialised community remains largely untested, as phylogenetic studies on corals have rarely included mesophotic samples and have long suffered from resolution issues associated with traditional sequence markers. RESULTS: Here, we used reduced-representation genome sequencing to conduct a phylogenomic assessment of the two dominant mesophotic genera of plating corals in the Indo-Pacific and Western Atlantic, respectively, Leptoseris and Agaricia. While these genome-wide phylogenies broadly corroborated the morphological taxonomy, they also exposed deep divergences within the two genera and undescribed diversity across the current taxonomic species. Five of the eight focal species consisted of at least two sympatric and genetically distinct lineages, which were consistently detected across different methods. CONCLUSIONS: The repeated observation of genetically divergent lineages associated with mesophotic depths highlights that there may be many more mesophotic-specialist coral species than currently acknowledged and that an urgent assessment of this largely unstudied biological diversity is warranted.

RESUMEN

Pleural effusions in children (PE) due to ventricle-peritoneal shunt (VPS) is very rare, with few cases reported. We present a new case of an infant with VPS who had a massive hydrothorax not associated with misplacement or migration of the distal catheter or with ascites. After the evacuation of the PE we managed the patient by adjusting the pressure of the adjustable valve (AV). Sequential thoracic ultrasounds showed a satisfactory outcome. We review the literature thoroughly and describe the possible pathophysiological mechanisms.

RESUMEN

Bezlotoxumab es un fármaco usado en la prevención de recurrencias de infección por Clostridium difficile, actuando mediante su unión a la toxina B de la bacteria, produciendo su inactivación. Este tipo de infección es muy frecuente en pacientes inmunodeprimidos, los cuales suelen presentar varias recurrencias que, junto con su enfermedad de base, pueden poner en compromiso la salud e incluso la vida del paciente. El objetivo de este trabajo es evaluar la efectividad de bezlotoxumab en la prevención de recaídas de infección por Clostridium difficile en una serie de cuatro pacientes. Para ello, se recopiló la información clínica necesaria y se anonimizó la base de datos antes de su análisis. Tras el análisis de nuestra serie de datos, obtuvimos resultados positivos ya que tres de los cuatro pacientes no sufrieron episodios de recurrencias en los cuatro meses posteriores a la administración de bezlotoxumab y ninguno presentó efectos adversos o intolerancias. Un paciente falleció un mes después de la administración de bezlotoxumab debido a la situación de inmunosupresión causada por su enfermedad de base y la infección no curada de Clostridium difficile. (AU)


Bezlotoxumab is a drug used in the treatment of recurrences of Clostridium difficile infection, acting by binding to the toxin B of the bacterium, producing its inactivation. This type of infection is very common in immunocompromised patients, who usually present several recurrences that, together with their underlying disease, can compromise the health and even the patient’s life. The aim of this study is to evaluate the effectiveness of bezlotoxumab in the prevention of four patients admitted for relapses of Clostridium difficile infection after the previous therapeutic failure of other drugs such as vancomycin, metronidazole or fidaxomycin. To do this, the necessary clinical information was collected and the database was anonymized before analysis. After analyzing our data series, we obtained positive results as three of the four patients did not suffer relapse episodes in the four months after bezlotoxumab administration and none had adverse effects or intolerances. One patient died one month after administration of bezlotozumab due to immunosuppression caused by his underlying disease and uncured Clostridium difficile infection. (AU)

RESUMEN

Tool wear monitoring is a critical issue in advanced manufacturing systems. In the search for sensing devices that can provide information about the grinding process, Acoustic Emission (AE) appears to be a promising technology. The present paper presents a novel deep learning-based proposal for grinding wheel wear status monitoring using an AE sensor. The most relevant finding is the possibility of efficient feature extraction form frequency plots using CNNs. Feature extraction from FFT plots requires sound domain-expert knowledge, and thus we present a new approach to automated feature extraction using a pre-trained CNN. Using the features extracted for different industrial grinding conditions, t-SNE and PCA clustering algorithms were tested for wheel wear state identification. Results are compared for different industrial grinding conditions. The initial state of the wheel, resulting from the dressing operation, is clearly identified for all the experiments carried out. This is a very important finding, since dressing strongly affects operation performance. When grinding parameters produce acute wear of the wheel, the algorithms show very good clustering performance using the features extracted by the CNN. Performance of both t-SNE and PCA was very much the same, thus confirming the excellent efficiency of the pre-trained CNN for automated feature extraction from FFT plots.

RESUMEN

Background: The net clinical benefit of ticagrelor over clopidogrel in acute coronary syndrome (ACS) has recently been questioned by observational studies which did not account for time-dependent confounders. We aimed to assess the comparative safety and effectiveness of ticagrelor vs. clopidogrel accounting for non-adherence in a real-life setting. Methods: This is a prospective, multicenter cohort study of patients with ACS discharged on ticagrelor or clopidogrel between 2015 and 2019. Major exclusions were previous intracranial bleeding, and the use of prasugrel or oral anticoagulation. Association of P2Y12 inhibitor therapy with 1-year risk of Bleeding Academic Research Consortium Type 3 or 5 bleeding; major adverse cardiac events (MACEs), a composite endpoint of all-cause death, nonfatal myocardial infarction (MI), nonfatal stroke, or urgent target lesion revascularization; definite/probable stent thrombosis; vascular death; and net adverse clinical event (a composite endpoint of major bleeding and MACE) were analyzed according to the "on-treatment" principle, using fully adjusted Cox and Fine-Gray regression models with doubly robust inverse probability of censoring weighted estimators. Results: Among 2,070 patients (mean age 63 years, 27% women, 62.5% ST-elevation MI), 1,035 were discharged on ticagrelor and clopidogrel, respectively. Ticagrelor-treated patients were younger and had few comorbidities, but high rates of medication non-compliance, compared with clopidogrel users. After comprehensive multivariate adjustments, ticagrelor did not increase the risk of major bleeding compared with clopidogrel [subhazard ratio, 1.40; 95% confidence interval (CI), 0.96-2.05], while proved superior in reducing MACE (hazard ratio 0.62; 95% CI, 0.43-0.90), vascular death (subhazard ratio, 0.71; 95% CI, 0.52-0.97) and definite/probable stent thrombosis (subhazard ratio, 0.54; 95% CI, 0.30-0.79); thereby resulting in a favorable net clinical benefit (hazard ratio 0.78; 95% CI, 0.60-0.98) compared with clopidogrel. Results from sensitivity analyses were consistent with those from the primary analysis, whereas those from the intention-to-treat (ITT) analysis went in the opposite direction. Conclusion: Among all-comers with ACS, ticagrelor did not significantly increase the risk of major bleeding, while resulting in a net clinical benefit compared with clopidogrel. Further research is warranted to confirm these findings in high bleeding risk populations.

RESUMEN

Food is one of the main challenges that health has in the twenty-first century. An inadequate diet together with the absence of physical activity and sedentary lifestyle are among the leading causes of preventable disease and premature death in Europe. In our country, the Mediterranean Diet model is being relegated in favor of a Western diet model. The consequence is the existence, more and more frequent, of health problems linked to diet, among which obesity stands out, an entity that is increasing year after year that is associated with numerous chronic diseases, especially those of a cardiovascular and metabolic nature.Objective:Analyze the feeding habits lifestyles of a military population and antropometric measures.Material and methods:Observational, cross-sectional and descriptive study. The data will be collected through questionnaires on feeding habits, lifestyles and associated diseases and of anthropometric measures.Results:The sample was performed by 107 persons. More than 70% of the sample needs changes in their diet, the data for adherence to the Mediterranean Diet are uneven, they were only correct in fruits, cereals, legumes, olive oil, milk and eggs. 69.79% of the sample performs physical activity in their free time. The overweight and obesity figures are 30.17% and 8.75% respectively.Conclusions:The results obtained provide us with knowledge on this area, to try to modify unhealthy patterns and styles, through educational programs and to use them as instruments of health promotion and disease prevention.

RESUMEN

Introducción: La ECMO es una técnica avanzada de soporte ventilatorio y circulatorio. Sin embargo, puede asociarse a complicaciones neurológicas. Se propone describir las características clínicas y el perfil de las complicaciones neurológicas en pacientes sometidos a ECMO. Pacientes y métodos: Estudio descriptivo retrospectivo de una serie de casos. Se realizó un análisis descriptivo y un análisis bivariado con la finalidad de comparar las principales variables clínicas de interés. Resultados: Se evaluó a 136 adultos sometidos a ECMO con edad promedio de 51 años (17-78). Las complicaciones neurológicas se presentaron en 51 pacientes (37,5%), de los cuales correspondieron a ictus 22 (16,17%); a encefalopatía hipóxica, 13 (9,5%); a hemorragia intracerebral (HIC), 12 (8,8%), y a hemorragia subaracnoidea (HSA), cuatro (2,9%). Siete (13,7%) de los pacientes con complicaciones neurológicas presentaron crisis epilépticas. Las complicaciones neurológicas se presentaron en 12 pacientes (23,53%) con la ECMO venovenosa y en 39 (76,47%) con la ECMO venoarterial (p = 0,86). La mortalidad global fue del 51,47% (70/136 pacientes) y del 64,7% (33/51) para la población con complicaciones neurológicas. La mortalidad en el ictus fue del 54,5% (12/22), del 91,6% (11/12) en la HIC y del 100% (4/4) en la HSA (p = 0,03). La mortalidad en la ECMO venoarterial fue del 77,14%, frente al 22,86% de la de la ECMO venovenosa (p = 0,015). Conclusiones: La ECMO es una herramienta terapéutica útil en casos de elevada gravedad clínica. En nuestro estudio, identificamos una elevada tasa de complicaciones neurológicas que contribuyen a la morbimortalidad asociada. La realización temprana de estudios de neuroimagen en estos casos podría permitir una detección temprana de estas complicaciones.(AU)


Introduction: ECMO is an advanced technique of ventilatory and circulatory support. However, it can be associated with neurological complications. The proposal is to describe the clinical characteristics and neurological complications profile in patients under ECMO support. Patients and methods: To descriptive a case series study. A descriptive and retrospective analysis and a bivariate analysis were performed in order to compare the main clinical variables of interest. Results: 136 adults undergoing ECMO with an average age of 51 years (17-78) were evaluated. Neurological complications were observed in 51 patients (37.5%), corresponding to stroke 22 (16.17%), hypoxic encephalopathy 13 (9.5 %), cerebral hemorrhage (HIC) in 12 (8.8%) and subarachnoid hemorrhage (HSA) in 4 patients (2.9%). Seven (13.7%) of patients with neurological complications had seizures. Neurological complications occurred in 23.53% in venovenous ECMO and in 76.47% with veno-arterial ECMO (p = 0.86). The overall mortality was 51.47% (70/136) for all patients in ECMO and 64.7% (33/51) for the population with neurological complications. The mortality in stroke was 54.5% (12/22), 91.6% (11/12) in HIC and 100% (4) in HSA (p = 0.03). Mortality was higher in veno-arterial ECMO (77.14%) versus venous-venous ECMO (22.86% of total), (p = 0.015). Conclusions: ECMO is a useful therapeutic tool in cases of high clinical severity. In our study, we identified a high rate of neurological complications that contribute to associated morbidity and mortality. Early neuroimaging studies in these cases could allow early detection of these complications.(AU)

RESUMEN

The aim of this work was to evaluate the technologies effect of cold extraction by centrifugation (CE) and ultrasound-assisted (US-CE) methods without adding water, on the avocado oil yield, nutritional composition, physicochemical characteristics, oxidative stability (oxidation temperature and time, besides activation energy) and accelerated shelf life regarding hexane extraction (control). The US-CE improved the physicochemical properties such as acidity, peroxides, and iodine indexes regarding CE and Control. US-CE improved the yield, nutritional quality of fatty acids, oxidative stability, shelf life, and ω-6/ω-3 ratio regarding CE. Furthermore, US-CE improved the ratio yield/time extraction of the oil and increased the oxidation temperature regarding control. The main advantage of oils extracted using CE and US-CE concerning control was higher oxidative stability. The most representative polyunsaturated fatty acids identified in all treatments were γ-linolenic and conjugated α-linolenic acids. α-linolenic acid was only detected in US-CE and control. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s10068-021-00940-w.

RESUMEN

One way in which the wine sector is reacting to the challenge of climate change is to develop plant material that is adapted to the new conditions. Such a strategy will allow the continuation of quality viticulture in traditional winemaking areas that will otherwise be abandoned. The objective of this study was to characterize the anthocyanin composition and content of selected intraspecific hybrids of Monastrell with two other varieties (Syrah and Cabernet Sauvignon). The experiment was carried out over three successive seasons, and the polyphenolic quality of the grapes and wines was assessed along with the adaptation of the hybrids to the high temperatures which will inevitably affect our area (south-eastern Spain). The results showed that, compared with grapes of the Monastrell variety and the wines made from them, most of the hybrids (MS10, MS34, and MC111) had a higher total anthocyanin concentration and overall content of acylated anthocyanins, depending on the year studied.

RESUMEN

This study focuses on the production and characterization of electrosprayed cashew gum (CG) microparticles that encapsulate ß-carotene. CG is an inexpensive, non-toxic polysaccharide obtained from Anacardium occidentale trees. Encapsulation of ß-carotene in CG was performed by electrospraying from two emulsion formulations (water : oil ratios 80:20 and 90:10 (v/v)) in which the dispersed phase consisted of ß-carotene dissolved in castor oil, and the continuous phase was a CG aqueous solution. Spherical particles with smooth surface and medium size between 3 and 6 µm were obtained. The particles produced from the 90:10 (v/v) emulsion showed a loading capacity of 0.075 ± 0.006 % and a minor amount of extractable ß-carotene, 10.75 ± 2.42 %. ATR-FTIR confirmed the absence of interaction between the particles' components. CG demonstrated to offer thermoprotection, and photoprotection for short periods of time. These results make CG a viable candidate to encapsulate bioactive compounds via electrospraying for agricultural, food and pharmaceutical applications.

RESUMEN

BACKGROUND: Fondaparinux is thought to have the most favorable risk-benefit profile among all anticoagulants in non-ST-elevation acute coronary syndrome (NSTE-ACS). However, conflicting findings exist whether this holds true in current clinical practice. We aimed to assess the net clinical benefit of fondaparinux versus enoxaparin in the contemporary management of NSTE-ACS. METHODS: Analysis of prospective multicenter registry data of NSTE-ACS patients who received fondaparinux or enoxaparin from February 2015, through December 2017. Survival models within a competing risks framework including site-specific random effects, were used to assess the composite of clinically relevant bleedings and major adverse cardiovascular events at 30 days. RESULTS: Of 2094 patients, 1724 (82%) received enoxaparin and 370 (18%) fondaparinux. Both groups were comparable except for a lower prevalence of diabetes and renal impairment, and greater use of transradial approach in the fondaparinux group. Multivariate analysis revealed a net clinical benefit in favour of fondaparinux versus enoxaparin (Subhazard Ratio [SHR] 0.59; 95%CI 0.37-0.92), mainly driven by a reduction in bleeding (SHR 0.57; 95%CI 0.37-0.89). Exploratory analysis suggested greater reductions in bleeding with fondaparinux among patients undergoing transradial approach, revealing a significant interaction between treatment and vascular access on the multiplicative scale (Pinteraction = 0.0056), but not on an additive scale (P = 0.457). Propensity-score-matching analysis yielded similar results. CONCLUSIONS: In contemporary management of NSTE-ACS, fondaparinux seems to provide a favorable net clinical benefit compared with enoxaparin, primarily driven by a bleeding reduction. Effect modification on the safety profile of fondaparinux by the vascular access approach warrants further investigation.

RESUMEN

The aim of this study was to determinate the effects of on-farm fasting periods and lairage times on the physiological behavioral indicators, and on the killing-out and meat quality traits in commercial pigs. Two-hundred and forty pigs were submitted to a 2X4X3 experimental design, with two on-farm periods (0 or 8 h), four lairage times (1, 8, 12, 24 h) of fasting and three replicates. The blood values of cortisol, urea, and non-esterified fatty acids were above the baseline values for the species Fasting on the farm, lairage time, and total fasting (on farm plus lairage time) had a significant effect on carcass yield and on the hot and cold carcass yields (P < 0.01), but not on live weight losses (P > 0.01). The total fast had significant effects on the pH values, color L * and on water-holding capacity of the meat (P < 0.01). Therefore, in favor of animal welfare and better meat quality we suggest a total fast no >12 h.

RESUMEN

The aim of this study was to evaluate the effect of a negative energy balance during the first third of gestation on metabolic, endocrine, and pregnancy recognition parameters in 2 beef cattle breeds adapted to semiextensive conditions. Seventy-five lactating Parda de Montaña and 40 Pirenaica multiparous cows rearing calves were synchronized and timed artificial inseminated (TAI) on day 76 postpartum. Cows were assigned to one of 2 diets (CONTROL or SUBNUT; 100% or 65% of their requirements supplied) until day 82 of gestation. Pregnancy was diagnosed 37 d post-TAI using ultrasound. Blood samples were obtained to determine metabolic (glucose, NEFA, ß-hydroxybutyrate, cholesterol, and urea) and endocrine (IGF-1) status throughout the first third of gestation and to determine the concentrations of progesterone and pregnancy-specific protein B (PSPB) in the peri-implantational period. Undernutrition affected both cow and calf performance. The CONTROL cows maintained BCS and BW, whereas SUBNUT cows had negative daily gains. The CONTROL lactating calves had higher BW gains than SUBNUT. These negative effects were more evident in the Pirenaica breed, which was more sensitive to undernutrition. The negative energy balance was reflected in the cows' metabolic profiles, with higher NEFA values and lower IGF-1 concentrations in SUBNUT cows. However, undernutrition did not affect dam pregnancy/TAI or pregnancy recognition and maintenance, confirming that during periods of undernourishment pregnant dams prioritize the allocation of dietary energy toward reproductive functions. Progesterone concentration on day 21 post-TAI (with a 4.8 ng/mL cut-off value) and PSPB on day 26 post-TAI (with a 0.57 ng/mL cut-off value) were determined as the earliest indicators to accurately establish dam pregnancy status, regardless of breed or nutrition treatment. In summary, early undernutrition affected cow performance and metabolic profiles and impaired lactating calf growth, but did not affect progesterone or PSPB concentrations or the pregnancy/TAI rate in suckled cows.
