    Boyeria irene (Fonscolombe, 1838) is a large dragonfly common in rivers and streams in southern Europe, but it is little known about the biometrical variations of their populations. In this paper, we test whether the time of the emergence period of this species differs in the same river, whether the larval size varies during the emergence period, and whether the distinct size variations are associated with the different river sections. Results have revealed that 1) female exuviae are larger than those of males, 2) except for the paraproct length, the exuviae have similar size across the entire river length, 3) size of the exuviae is larger in the first period of emergence than in the second one. A difference in emergence duration across the three river sections has been recorded.info:eu-repo/semantics/publishedVersio

    Antimicrobial drugs applied topically offer several advantages. However, the widespread use of antibiotics has led to increasing antimicrobial resistance. One interesting approach in the drug discovery process is drug repurposing. Disulfiram, which was originally approved as an anti-alcoholism drug, offers an attractive alternative to treat topical multidrug resistance bacteria in skin human infections. This study aimed to evaluate the biopharmaceutical characteristics of the drug and the effects arising from its topical application in detail. Microdilution susceptibility testing showed antibacterial activity against Gram-positive bacteria Staphylococcus aureus and Streptococcus pyogenes. Dermal absorption revealed no permeation in pig skin. The quantification of the drug retained in pig skin demonstrated concentrations in the stratum corneum and epidermis, enough to treat skin infections. Moreover, in vitro cytotoxicity and micro-array analyses were performed to better understand the mechanism of action and revealed the importance of the drug as a metal ion chelator. Together, our findings suggest that disulfiram has the potential to be repurposed as an effective antibiotic to treat superficial human skin infections

    The nervous necrosis virus (NNV) leads to viral encephalopathy and retinopathy (VER) disease in more than 170 fish species, mainly from marine habitats. It replicates in the central nervous tissues, reaching up to 100% mortalities after a few days of infection, mainly in the larvae and juvenile stages. This is continuously spreading and affecting more species, both wild and cultured, posing a risk to the development of the aquaculture industry. In the Mediterranean Sea, it mainly affects European sea bass (Dicentrarchus labrax) and some grouper species (Epinephelus spp.). Interestingly, in the gilthead seabream (Sparus aurata), typically resistant to common NNV strains, great mortalities in hatcheries associated with typical clinical signs of VER have been confirmed to be caused by RGNNV/SJNNV reassortants. Thus, we have evaluated the susceptibility of seabream larvae to either RGNNV/SJNNV or SJNNV/RGNNV reassortants, as well as the larval immunity. Based on our results we can conclude that: (i) gilthead seabream larvae are susceptible to infection with both NNV reassortant genotypes, but mainly to RGNNV/SJNNV; (ii) virus replicated and infective particles were isolated; (iii) larval immunity was correlated with larval survival; and (iv) larval resistance and immunity were correlated with age of the larvae. Further investigations should be carried out to ascertain the risks of these new pathogens to Mediterranean larviculture

    Objective: To describe the results of the home enteral nutrition (HEN) registry of the NADYA-SENPE group in 2011 and 2012. Material and methods: We retrieved the data of the patients recorded from January 1st 2011 to December 31st 2012. Results: There were 3021 patients in the registry during the period from 29 hospitals, which gives 65.39 per million inhabitants. 97.95% were adults, 51.4% male. Mean age was 67.64 ± 19.1, median age was 72 years for adults and 7 months for children. Median duration with HEN was 351 days and for 97.5% was their first event with HEN. Most patients had HEN because of neurological disease (57.8%). Access route was nasogastric tube for 43.5% and gastrostomy for 33.5%. Most patients had limited activity level and, concerning autonomy, 54.8% needed total help. Nutritional formula was supplied from chemist’s office to 73.8% of patients and disposables, when necessary, was supplied from hospitals to 53.8% of patients. HEN was finished for 1,031 patients (34.1%) during the period of study, 56.6% due to decease and 22.2% due to recovery of oral intake. Conclusions: Data from NADYA-SENPE registry must be explained cautiously because it is a non-compulsory registry. In spite of the change in the methodology of the registry in 2010, tendencies regarding HEN have been maintained, other than oral routeObjetivos: Describir los resultados del registro de nutrición enteral domiciliaria (NED) del grupo NADYASENPE de los años 2011 y 12. Material y métodos: Se recopilaron los datos introducidos en el registro desde el 1 de enero de 2011 al 31 de diciembre de 2012. Resultados: Hubo 3021 pacientes en el registro durante el periodo, procedentes de 29 hospitales, lo que da una prevalencia de 65,39 casos por millón de habitantes. 97.95% fueron adultos, 51,4% varones. La edad media fue 67,64 ± 19,1 años y la mediana 72 años para los adultos y 7 meses para los niños. La duración media de la NED fue 351 días y para el 97,5% fue el primer episodio con NED. La mayoría de pacientes tenían NED por una enfermedad neurológica (57,8%). La vía de acceso fue sonda nasogástrica para el 43,5% y gastrostomía para el 33,5%. La mayoría de pacientes tuvieron un nivel de actividad física limitado y, respecto a la autonomía, 54,8% necesitaba ayuda total. La fórmula de nutrición se suministró desde las oficinas de farmacia para el 73,8% y los fungibles, cuando fueron necesarios, desde los hospitales para el 53,8%. La NED se suspendió en 1.031 pacientes (34,1%) durante el periodo de estudio, 56,6% debido a fallecimiento y 22,2% debido a recuperación de la vía oral. Conclusiones: Los datos del registro NADYA-SENPE deben ser interpretados con precaución ya que se trata de un registro voluntario. A pesar del cambio de metodología del registro en 2010, las tendencias en NED se han mantenido, salvo la importancia cuantitativa de la vía ora

    The disruption of the circadian system in humans has been associated with the development of chronic illnesses and the worsening of pre-existing pathologies. Therefore, the assessment of human circadian system function under free living conditions using non-invasive techniques needs further research. Traditionally, overt rhythms such as activity and body temperature have been analyzed separately; however, a comprehensive index could reduce individual recording artifacts. Thus, a new variable (TAP), based on the integrated analysis of three simultaneous recordings: skin wrist temperature (T), motor activity (A) and body position (P) has been developed. Furthermore, we also tested the reliability of a single numerical index, the Circadian Function Index (CFI), to determine the circadian robustness. An actimeter and a temperature sensor were placed on the arm and wrist of the non-dominant hand, respectively, of 49 healthy young volunteers for a period of one week. T, A and P values were normalized for each subject. A non-parametric analysis was applied to both TAP and the separate variables to calculate their interdaily stability, intradaily variability and relative amplitude, and these values were then used for the CFI calculation. Modeling analyses were performed in order to determine TAP and CFI reliability. Each variable (T, A, P or TAP) was independently correlated with rest-activity logs kept by the volunteers. The highest correlation (r = −0.993, p<0.0001), along with highest specificity (0.870), sensitivity (0.740) and accuracy (0.904), were obtained when rest-activity records were compared to TAP. Furthermore, the CFI proved to be very sensitive to changes in circadian robustness. Our results demonstrate that the integrated TAP variable and the CFI calculation are powerful methods to assess circadian system status, improving sensitivity, specificity and accuracy in differentiating activity from rest over the analysis of wrist temperature, body position or activity alone

Métodos: se recopilaron los pacientes introducidos en el registro desde el 1 de enero al 31 de diciembre de 2014 y la mismas fechas de 2015, y se procedió al análisis descriptivo y analítico de los datos. Resultados: en el año 2014, se registraron 3.749 pacientes y en 2015, 4.202; la prevalencia fue de 80,58 pacientes/millón de habitantes en el año 2014 y de 90,51 en 2015. Por sexos, hubo un 49,9% de mujeres en 2014 y un 50,3% en 2015. La edad media fue de 73 años (IIQ 59-83) en ambos años. Finalizaron 684 episodios de NED en 2014 y 631 en 2015, la causa principal fue el fallecimiento en el 54,9% y 50,4% de los casos, respectivamente. Los portadores de sonda nasogástrica presentan una edad media superior a los pacientes con cualquier otra vía (p < 0,001). Se registraron 67 pacientes pediátricos en 2014 (56,7% niñas) y 77 en 2015 (55,8% niñas). La vía principal de administración fue la gastrostomía en el 52,0% de los casos de 2014 y sonda nasogástrica en el 50,8% de los casos de 2015. La causa principal de fi nalización de la nutrición fue el fallecimiento (57,1% en 2014 y 38,5% en 2015). Se observó que los niños más pequeños eran los que se alimentaban preferentemente por SNG (p 0,004 vs. 0,002).Tanto en pacientes pediátricos como en adultos el diagnóstico principal que motivó la necesidad de NED fue la enfermedad neurológica que cursa con afagia o disfagia severa. Conclusiones: se ha incrementado el número de pacientes del registro, así como el número de centros participantes y el número medio de pacientes comunicados por cada centro respecto a años anteriores, sin que se hayan modificado sustancialmente las características de los pacientes, salvo mayor duración de los episodiosObjective: To present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the years 2014 and 2015. Methods: From January 1st 2014 to December 31st 2015 the HEN registry was recorded and afterwards a further descriptive and analytical analysis was done. Results: In 2014, 3749 patients were recorded, and 4202 in 2015; prevalence was 80.58 patients/one million inhabitants in Spain in 2014 and 90.51 in 2015. There were 49.9% females in 2014 and 50.3% in 2015. Median age was 73 years (IQI 59-83) in 2014 as well as in 2015. 684 episodes fi nished in 2014 and 631 in 2015, with death as the main cause, in 54.9% and 50.4%, respectively. The ones who were fed through nasogastric tube had a mean age higher than the ones fed by any other route (p-value < 0.001). Sisty-seven paediatric patients were recorded in 2014 (56.7% females) and 77 in 2015 (55.8% females). Median age at the beginning of HEN among children was 5 months in 2014 and 5 months in 2015. The main route of administration was gastrostomy, in 52.5% in 2014 and nasogastric tube in 50.8% in 2015. 7 episodes fi nished in 2014 and 13 in 2015, having death as the main cause (57.1% in 2014 and 38.5% in 2015). It was found that were younger children the ones who were mainly fed by nasogastric tubes (p-value 0.004 vs. 0.002). Among paediatric patients as well as adults, the main diagnosis leading to HEN was neurological disease which gives aphagia or severe dysphagia. Conclusions: There has been an increase in the number of patients in the registry as well as the participating centers and the number of patients per center, without any signifi cant change in the characteristics of the patients other than longer duration of the episode
