Multispecies mass mortality in the Beagle Channel associated with paralytic shellfish toxins.

The Beagle Channel is a Subantarctic semi-estuarine environment at the southern tip of South America, where intoxication events associated with harmful algal blooms have been reported since 1886, including a world record in toxicity due to Alexandrium catenella in 1992. Toxic algae affect public health and ecosystem services, particularly mussel aquaculture and fisheries management. During the austral summer of 2022, an intense bloom of A. catenella (5 × 104 cells L-1) occurred in the Beagle Channel, leading to the second most toxic event in the area, with mussel toxicity reaching 197,266 µg STXeq kg-1. This event was synchronous with the mortality of marine organisms from different trophic levels and terrestrial fauna, i.e., two Fuegian red foxes and a southern caracara. Stomach content and liver samples from dead kelp gulls (Larus dominicanus), Magellanic penguins (Spheniscus magellanicus), papua penguins (Pygoscelis papua), and imperial cormorants (Leucocarbo atriceps), presented variable paralytic shellfish toxins (PST) levels (up to 3427 µg STXeq kg-1) as measured by high performance liquid chromatography (HPLC), suggesting that deaths were associated with high PST toxicity level. The different toxin profiles found in phytoplankton, zooplankton, squat lobsters (Grimothea gregaria), Fuegian sprat (Sprattus fuegensis), and seabirds evidenced possible toxin transformation along the food web and the possible transfer vectors. The unexpected detection of PST in terrestrial fauna (up to 2707 µg STXeq kg-1) suggested intoxication by scavenging on squat lobsters, which had high toxicity (26,663 µg STXeq kg-1). PST trace levels were also detected in a liver sample of a dead false killer whale (Pseudorca crassidens), an oceanic odontocete stranded on the coast during the bloom. Overall, our results denote the exceptional nature of the toxic, multispecies mortality event and that toxins may propagate to several levels of the food web in this Subantarctic environment.

The hilum of the lung: Two classical radiological signs to decipher it.

Assessing the hilum of the lung is a common challenge in daily practice because various structures converge in this complex anatomic region. Because chest X-rays are widely available and deliver relatively low doses of radiation, they continue to be the most common imaging test, although new imaging modalities have decreased the use of chest X-rays for differentiating between true abnormalities and superimposed lung opacities. This article reviews the literature and describes the principal anatomic relations of the lung hilum through illustrative cases to enable the two most important radiologic signs to be identified: "hilum overlay" and "hilum convergence". In the initial imaging evaluation of patients with cardiothoracic disease, knowledge of these basic principles facilitates the three-dimensional location of lesions in a single-plane image, optimizing time and resources.

El hilio pulmonar, dos signos radiológicos clásicos para descifrarlo / The hilum of the lung: two classical radiological signs to decipher it

El análisis del hilio pulmonar es un reto frecuente en la práctica diaria, por tratarse de una región anatómica compleja donde confluyen varias estructuras. La radiografía de tórax, por su alta accesibilidad y baja dosis de radiación, se mantiene como la primera técnica de imagen solicitada, pese a que las nuevas modalidades han disminuido su uso en el momento de diferenciar verdaderas anormalidades de opacidades pulmonares superpuestas. Se realizó una revisión bibliográfica que ilustra mediante casos didácticos sus principales relaciones anatómicas, lo que permite identificar los signos radiológicos que revisten mayor importancia: “sobreposición hiliar” y “convergencia hiliar”. En la valoración inicial del paciente con patología cardiotorácica, tener conocimiento de estos principios básicos facilita localizar tridimensionalmente lesiones en una imagen planar, optimizando tiempo y recursos.(AU)

Scale-up of electrokinetic permeable reactive barriers for the removal of organochlorine herbicide from spiked soils.

This work aims to shed light on the scale-up a combined electrokinetic soil flushing process (EKSF) with permeable reactive barriers (PRB) for the treatment of soil spiked with clopyralid. To do this, remediation tests at lab (3.45 L), bench (175 L) and pilot (1400 L) scales have been carried out. The PRB selected was made of soil merged with particles of zero valent iron (ZVI) and granular activated carbon (GAC). Results show that PRB-EKSF involved electrokinetic transport and dehalogenation as the main mechanisms, while adsorption on GAC was not as relevant as initially expected. Clopyralid was not detected in the electrolyte wells and only in the pilot scale, significant amounts of clopyralid remained in the soil after 600 h of operation. Picolinic acid was the main dehalogenated product detected in the soil after treatment and mobilized by electro-osmosis, mostly to the cathodic well. The transport of volatile compounds into the atmosphere was promoted at pilot scale because of the larger soil surface exposed to the atmosphere and the electrical heating caused by ohmic losses and the larger interelectrode gap.

ACTN3 R577X polymorphism related to sarcopenia and physical fitness in active older women.

BACKGROUND: As the population is getting older, physical activity promotion becomes a good strategy to increase quality of life in the elderly; but genetic condition also plays an important role. The purpose of this study was to examine the association of the ACTN3 R577X polymorphism with physical fitness and muscle mass in physically active older women. METHODS: A cross-sectional study was performed with two groups of older women who practiced physical exercise regularly. The first cohort comprised 164 women (age 69.7 ± 3.2 years) and the second cohort 131 women (age 78.5 ± 3.0 years). The main outcome measures were anthropometric measures with assessment of sarcopenia and sarcopenic obesity, self-reported physical activity EXERNET questionnaire (EEPAQ), evaluation of physical fitness (muscle strength and flexibility test), and ACTN3 genotyping. RESULTS: Women above 75 years old with allele R presented a higher risk of experiencing sarcopenia compared to ACTNR XX homozygous women (odds ratio 0.356, 95% confidence interval 0.139-0.915, p = 0.026). Furthermore, statistically significant differences were found in the chair stand test (p = 0.04), as well as in the sit and reach test (p = 0.01), with better results for women below 75 years old with the ACTN3 XX genotype. CONCLUSIONS: Sarcopenia and physical fitness show differences based on the ACTN3 R577X genotype in active older women.

Evidence on the discrimination of quinoa grains with a combination of FT-MIR and FT-NIR spectroscopy.

Quinoa is considered as a valuable re-emergent crop due to its nutritional composition. In this study, five quinoa grains from different geographical origin (Real, CHEN 252, Regalona, BO25 and UDc9) were discriminated using a combination of FT-MIR and FT-NIR spectra as input for principal component analysis (PCA), cluster analysis (CA) and soft independent modelling class analogy (SIMCA). The results obtained from PCA and CA show a great power of discrimination, with an average silhouette width value of 0.96. Moreover, SIMCA showed an error rate and accuracy values of 0 and 1 respectively with only 4% misclassified samples. A relationship between each principal component and the most important variables for the discrimination were mainly due to vibrations of several oleofins groups (C-H, C-H2, C-H3), alkene group (-CH=CH-), hydroxyl group (O-H) and Amides I and II vibrational modes.

Influencia del comportamiento visual en las decisiones en el bloqueo de voleibol / Visual Behavior Influence on Decision in Volleyball Blocking

El objetivo del presente estudio fue conocer la influencia del comportamiento visual (localización, número y duración de las fijaciones visuales) sobre la toma de decisiones en la acción del bloqueo en voleibol. Se analizó el comportamiento visual de 38 jugadoras de voleibol (23.9 ± 4.2 años), que competían de manera federada, mediante el sistema de registro de movimientos oculares (Mobile Eye) durante la visualización de secuencias de video proyectadas a tamaño real. Los modelos de regresión obtenidos muestran que se obtienen mayores porcentajes de acierto cuando la duración de las fijaciones es reducida en las zonas HC y CB, y cuando aumenta el número de fijaciones en la zona BM y disminuye en la zona CB

The purpose of this study was to determine the influence of visual behaviour (visual fixation location, number and duration) on decision-making in volleyball blocking. The visual behavior of 38 volleyball players (23.9 ± 4.2 years), who took part in federated competition, was analyzed with the eye tracking system (Mobile Eye) during visualization of real size video sequences. Regression models show that higher success percentages were obtained when the duration of fixations is low in HC and CB areas, and when the number of fixations increases in BM zone and decreases in CB zone

Does fitness attenuate the relationship between changes in sitting time and health-related quality of life over time in community-dwelling older adults? Evidence from the EXERNET multicenter longitudinal study.

OBJECTIVE: To assess the relationship between fitness levels and components, sitting time and health-related quality of life (HRQoL), over time among community-dwelling older adults. METHODS: Three different sitting trajectories were calculated: (i) no change; (ii) decrease; and (iii) increase in ST, between baseline and follow-up. Fitness was assessed using the aerobic capacity, upper and lower limb strength, and total fitness. Participants were classified into higher (75th percentile or above) or lower (below 75th percentile) fitness levels, using the fitness tests. HRQoL scores at follow-up were compared to the three different sitting time trajectories within and across both the higher and the lower fitness groups for each of the three fitness indexes. RESULTS: Greater HRQoL scores were observed in those participants that decreased their ST as compared with those increasing their sitting time over time for participants classified in the lower end of their aerobic capacity or total fitness index. No differences were detected in HRQoL scores in people classified in the higher fitness level group for any of the fitness indexes. Participants that increased or did not change their sitting time and who were classified in the higher fitness end of aerobic capacity and total fitness index self-reported higher HRQoL scores when compared with those in the lower fitness end. CONCLUSION: Increased sitting time over time is associated with poorer HRQoL in older adults. Higher fitness levels could help attenuate the negative impact of sitting over time.

Registro unicéntrico de ablaciones de taquiarritmias cardíacas en pacientes pediátricos. Seguridad y eficacia / Single-center registry of ablations of arrhythmogenic substrates in pediatric patients. Safety and efficacy

Introducción: Las taquiarritmias en pediatría son uno de las principales motivos cardiológicos de consulta a la guardia. Durante el primer año de vida presentan una significativa morbi-mortalidad, por lo que el tratamiento farmacológico inmediato es fundamental para reducir la misma. Hasta los 3 años existe la posibilidad de curación espontánea en un porcentaje de éstos pacientes. La indicación de procedimientos de ablación durante los primero 4 años de vida se limita a casos refractarios al tratamiento antiarrítmico, dado que cuanto menor peso presenta el paciente, más pequeño es el corazón y más riesgoso es el mismo. Las taquicardias en pacientes con cardiopatía empeora el pronóstico de la misma. A pesar que el tratamiento farmacológico ha permitido el control de la gran mayoría de ellas, en muchos casos se requieren más de una droga antiarrítmica, con mayor exposición a efectos adversos, y en muchos otros se vuelven refractarias. En las últimas 3 décadas se ha desarrollado en forma exponencial el tratamiento de las taquiarritmias por medio de la ablación por radiofrecuencia o por frío (crioablación). Estos procedimientos han permitido obtener la curación de la mayor parte de las taquiarritmias en pediatría. En nuestro trabajo se evaluaron las indicaciones de dichos procedimientos en una población pediátrica, como así también la tasa de éxito, recurrencia, y la morbimortalidad tanto globalmente, como en cada arritmia (AU)

In children, tachyarrhythmias are one of the main reasons for cardiological consultation at the Department of Emergency. In the first year of life, they are associated with significant morbiditymortality and therefore, immediate drug treatment is essential up to 3 years of age. The indication of ablation procedures during the first 4 years of life is limited to patients refractory to antiarrhythmic treatment, since the lower weight of the patient, the smaller the heart and the riskier the intervention. In patients with heart disease, tachycardia worsens the prognosis. Although pharmacological treatment controls the vast majority of tachyarrhythmias, more than one antiarrhythmic drug is often required, leading to greater exposure to adverse effects, and many become refractory. Over the past three decades, treatment of tachyarrhythmias has developed exponentially with the advent of radiofrequency or cold ablation (cryoablation). These procedures have led to the cure of most tachyarrhythmias in children. Our study assessed the indications for these procedures in a pediatric population, as well as the success and recurrence rates, and morbidity both overall and of each arrhythmia episode (AU)

Is Sitting Time Related with Physical Fitness in Spanishelderly Population? The EXERNET Multicenter Study.

BACKGROUND: Older adults spend most of their waking hours performing sedentary activities. The influence of these lifestyle patterns on the physical fitness (PF) levels of this population has not yet been sufficiently investigated. OBJECTIVE: The aim of the study was to examine whether sedentary behavior (SB) (h•d-1sitting) is associated with PF, and specifically to analyze whether sitting >4 h•d-1 is associated with higher risk of having lower levels of fitness in seniors. DESIGN: EXERNET multi-center study. PARTICIPANTS AND SETTINGS: A representative sample of 3136 non-institutionalized elderly (aged 72.2±5.3 years), from 6 Regions of Spain were included in the study. MEASUREMENTS: PF was assessed using 8 different tests from the EXERNET battery. Lifestyle patterns were collected using a validated questionnaire. ANOVA was used to compare the groups according to the hours of sitting. Binary logistic regression was used to calculate the association between the SB and low levels of fitness. RESULTS: For both genders, those who spent sitting >4 h•d-1 had lower levels of balance, agility, walking speed and aerobic endurance (p<0.001). Sedentary men also had less strength of lower extremities (p<0.05), whereas, sedentary women were less flexible in the lower extremities (p<0.001). More than 4 h•d-1 sitting was associated, in men, to higher odds for having low strength (lower extremities), agility, flexibility (lower extremities) and aerobic endurance (p<0.05); and in women, to higher risk of low balance, strength (lower and upper extremities), flexibility (lower extremities), agility, walking speed and aerobic endurance (p<0.05). CONCLUSIONS: Seniors that sit >4 h•d-1 have lower levels of fitness and this behavior is related with an increased risk of having low levels of PF in this population.

Application of a multiphase microreactor chemostat for the determination of reaction kinetics of Staphylococcus carnosus.

Bioreactors at the microliter scale offer a promising approach to accelerate bioprocess development. Advantages of such microbioreactors include a reduction in the use of expensive reagents. In this study, a chemostat operation mode of a cuvette-based microbubble column bioreactor made of polystyrene (working volume of 550 µL) was demonstrated. Aeration occurs through a nozzle (Ø ≤ 100 µm) and supports submerged whole-cell cultivation of Staphylococcus carnosus. Stationary concentrations of biomass and glucose were determined in the dilution rate regime ranging from 0.12 to 0.80 1/h with a glucose feed concentration of 1 g/L. For the first time, reaction kinetics of S. carnosus were estimated from data obtained from continuous cultivation. The maximal specific growth rate (µmax = 0.824 1/h), Monod constant (KS = 34 × 10- 3gS/L), substrate-related biomass yield coefficient (YX/S = 0.315 gCDW/gS), and maintenance coefficient (mS = 0.0035 gS/(gCDW·h)) were determined. These parameters are now available for further studies in the field of synthetic biology.

Imágenes en divertículos del tubo digestivo: localizaciones infrecuentes. serie de casos / Imaging in infrequent digestive diverticula: case series

Los divertículos se pueden localizar en todo el tubo digestivo (TD): esófago, estómago, duodeno, yeyuno, íleon, apéndice, colon. Son infrecuentes, salvo en colon. Sus manifestaciones clínicas son inespecíficas, con difícil diagnóstico y mayor riesgo de complicaciones. Se presenta una serie de divertículos digestivos atípicos, mostrando las características imagenológicas multimodalidad y describir los hallazgos claves. Es una revisión retrospectiva en el archivo computacional de nuestra institución. Selección de casos de divertículos de presentación inhabitual por sus características, localización u origen. En esófago los divertículos de Zenker y Killian-Jamieson. En estómago los divertículos gástricos infrecuentes. Los divertículos en intestino delgado tienen baja prevalencia, el más frecuente en duodeno. Los divertículos colónicos pueden tener una localización o presentación atípica. Los divertículos apendiculares y Meckel presentan baja prevalencia. Los divertículos digestivos son infrecuentes, excepto los colónicos. El radiólogo debe estar familiarizado con las diferentes ubicaciones de ellos, para reconocerlos y poder diagnosticarlos.

Diverticula may occur in any segment of the digestive tract: esophagus, stomach, duodenum, jejunum, ileum, appendix, and colon. Its clinical manifestations are nonspecifi which may turn diffiult an early diagnosis, leading to a higher risk of complications. We present a cases serie of atypical digestive diverticula and to describe the fidings on the different imaging techniques. We performed a retrospective review on the imaging computer archives of our institution. The atypical diverticula were selected. Zenker and Killian-Jamieson's diverticulums in esophagus. In stomach ocasionally gastric diverticula. Diverticula in small intestine have a low prevalence, the most common location is duodenum. Colonic diverticula may present a atypical location or presentation. The appendicular and Meckel diverticuli are uncommon. The digestive diverticula are uncommon, except the colonic ones. The radiologist must be familiar with it's different locations in order to be able to recognize it and diagnose it properly.

El entrenamiento perceptivo de bloqueadoras juveniles de voleibol / Perceptive training of youth volleyball blockers

Este estudio analiza la eficacia de un programa de entrenamiento perceptivo basado en la orientación de la atención para la mejora de la toma de decisiones y el rendimiento en la acción de bloqueo de voleibol. 16 jugadoras juveniles fueron distribuidas en tres grupos: vídeo (n=6), que recibió ocho sesiones de entrenamiento en vídeo; mixto (n=5), que recibió 4 sesiones en vídeo y 4 sesiones de práctica en campo; y control (n=5), que completó las pruebas de evaluación. Los resultados muestran cómo el programa de entrenamiento mejoró la toma de decisiones de las jugadoras, ya que redujeron su tiempo de reacción (F(1,13)=9,237, p=0,009, ηp2=0,415) manteniendo el mismo porcentaje de aciertos. Sin embargo, es necesaria la práctica en campo para lograr transferir dichos aprendizajes al juego real, ya que sólo el grupo mixto mejora el porcentaje de aciertos en el test de rendimiento en campo (F(2,13)=8,608, p=0,004, ηp2=0,570; t(4) =-6,216, p=0,003) (AU)

This study examines the effectiveness of a training program based on perceptual orientation of attention for improving decision-making and performance in the blocking action of volleyball. 16 youth players were divided into three groups: video (n=6), which received eight perceptual training sessions by video; mixed (n=5), which received only half of the sessions by video, combined with practical training in the field; and control (n=5), which just completed pre-test and post-test tests. Results show how orientation of attention to relevant areas of information improved decision-making of the youth volleyball players because they reduced their reaction time (F(1,13)=9,237, p=0,009, ηp2=0,415) maintaining the same percentage of success. However, the practice on the field is necessary to achieve transfer those learning to the real game, because only mixed group improves the percentage of success in the field performance test (F(2,13)=8,608, p=0,004, ηp2=0,570; t(4)=-6,216, p=0,003) (AU)

Cookies elaborated with oat and common bean flours improved serum markers in diabetic rats.

BACKGROUND: Common beans have been associated with anti-diabetic effects, due to its high content of bioactive compounds. Nevertheless, its consumption has decreased worldwide. Therefore, there is an increasing interest in the development of novel functional foods elaborated with common beans. The aim of this study was to evaluate the anti-diabetic effect of oat-bean flour cookies, and to analyze its bioactive composition, using commercial oat-wheat cookies for comparative purposes. RESULTS: Oat-bean cookies (1.2 g kg-1 ) slightly decreased serum glucose levels (∼1.1-fold) and increased insulin levels (∼1.2-fold) in diabetic rats, reducing the hyperglycemic peak in healthy rats (∼1.1-fold). Oat-bean cookies (0.8 and 1.2 g kg-1 ) exerted a greater hypolipidemic effect than commercial oat-wheat cookies (1.2 g kg-1 ), as observed in decreased serum triglycerides and low-density lipoprotein cholesterol. Furthermore, the supplementation with 1.2 g kg-1 oat-bean cookies decreased atherogenic index and serum C-reactive protein levels, suggesting their cardioprotective potential. The beneficial effect of oat-bean cookies was associated with their high content of dietary fiber and galacto oligosaccharides, as well as chlorogenic acid, rutin, protocatechuic acid, ß-sitosterol and soyasaponins. CONCLUSION: These results suggest that common beans can be used as functional ingredients for the elaboration of cookies with anti-diabetic effects. © 2017 Society of Chemical Industry.

[Relation between educational level and body composition in non-institutionalized elderly: The elderly EXERNET multi-center study.] / Relación entre el nivel educativo y la composición corporal en personas mayores no institucionalizadas: proyecto multi-céntrico EXERNET.

OBJECTIVE: There is an inverse association between educational level and body composition; however this association has strongly focused in young and adults population. The aim of this study was to analyze the educational levels attained in overweight and obesity Spanish elderly and to investigate if there was a correlation between having a low educational level and the risk of having overweight, central obesity or excess fat mass during the aging process. METHODS: A representative sample of 2706 elderly (629 men and 2077 women; mean age of 72.1 ± 5.3 years) from Spain were assessed in the elderly EXERNET multi-center study between 2008 and 2009. Body composition was assessed in all subjects by bioelectrical impedance. ANCOVA was used to compare the averages between the groups. Logistic regression was used to calculate the association between educational level and the risk of having overweight, central fat or obesity. RESULTS: We observed significances between waist circumference and educational level in both sex (men 96.6 cm, women 86.3 cm); (p less than 0.05 and p less than 0.01, respective). There is an inverse association between the academic level, fat mass (29.5 kg) and percentage of body fat (40.8%) in women (p less than 0.05, p less than 0.01, respectively). No differences were observed in men. CONCLUSIONS: low educational level increases the possibility of having overweight or obesity in women and to have an increased waist circumference in both sexes.

OBJETIVO: El nivel educacional se ha relacionado inversamente con la composición corporal, sin embargo esta asociación ha sido evidenciada mayoritariamente en población joven y adulta. El objetivo del presente estudio fue evaluar la relación entre la composición corporal de las personas mayores de 65 años y su nivel educativo, y determinar si tener un nivel educativo alto puede prevenir el riesgo de padecer sobrepeso, obesidad central o exceso de grasa durante la senectud. METODOS: El estudio se realizó entre los años 2008-2009, sobre una muestra representativa de personas mayores de España (2.706; 629 varones, 2.077 mujeres; edad media 72,1 ± 5,3 años), pertenecientes al Proyecto Multi-céntrico EXERNET. La composición corporal se evaluó mediante bio-impedancia eléctrica. Se utilizó ANCOVA para determinar las diferencias entre grupos. La asociación entre el nivel educativo y el riesgo de padecer sobrepeso, obesidad central o exceso de grasa se analizó mediante regresión logística. RESULTADOS: En el perímetro de cintura, los hombres y mujeres con mayor nivel de estudios presentaron 96,6 cm y 86,3 cm, respectivamente (pmenor de 0,05 y p menor de 0,01, respectivamente). Las mujeres con menor nivel de estudios presentaron 29,5 kg de masa grasa total y 40,8% de masa grasa (p menor de 0,05 y p menor de 0,01, respectivamente). Los varones no presentaron diferencias en estas mediciones. CONCLUSIONES: Poseer un bajo nivel de estudios aumenta las posibilidades de padecer sobrepeso y obesidad en las mujeres y de tener mayor perímetro de cintura en ambos sexos.
