Prevalence and factors associated with a higher risk of neck and back pain among permanent wheelchair users: a cross-sectional study

[EN] Study design: Cross-sectional study. Objectives: To determine the prevalence of, and factors associated with, spinal pain among wheelchair users. Setting: Four Spanish hospitals specialized in providing care for wheelchair users. Methods: Persons who had used a wheelchair for a median (IRQ) of 10 (5;19) years, 27% of them due to reasons other than spinal cord injury, were recruited consecutively (n = 750). Data on 43 demographic, psychosocial, ergonomic, and clinical variables were collected, and analyzed. Main outcome measures were: Point prevalence of neck (NP), thoracic (TP), low back pain (LBP), and pain at any spinal level (PASL); and factors associated with them. Results: Point prevalence was 56% for NP, 54% for TP, 45% for LBP, and 76% for PSAL. PASL was associated with a lower quality of life (OR (95% CI) 0.91 (0.86; 0.97)). Multivariable regression models showed that the main factors associated with significant pain (≥1.5 VAS points) were: (a) For NP: Cervical spinal injury and wheelchair seat cushion thickness, (b) For TP: Thoracic spinal injury and sagittal index, (c) For LBP: Thoracic or lumbar spinal injury, with some sensitivity remaining, (d) For PASL: Being female, living alone, and using a non-power wheelchair. Discrimination (AUC) of these models ranged between 0.638 and 0.818. p-values in the Hosmer-Lemeshow test ranged between 0.420 and 0.701. Conclusions: Prevalence of spinal pain among wheelchair users is high. It is associated with a lower quality of life. Future studies should assess whether using a power wheelchair affects PASL, and if the thickness of seat cushion affects NP. Sponsorship: Spanish Back Pain Research NetworkS

Dimensiones, rasgos y relaciones del líder y su grupo: liderazgo versus autonomía

Los tiempos actuales llevan a ver al jefe como un igual, inclusive a criticarlo y desafiarlo. En años pasados el jefe contaba con apoyo y respeto y se le veía como un superior; ahora el jefe debe contar con la habilidad para manejar situaciones y tratar a sus “empleados” adecuadamente para ganarse así su obediencia y lealtad, éste es un mérito que sólo puede obtener el que es líder. En este artículo vamos a intentar hacer un breve recorrido por las distintas dimensiones y tipos de liderazgo, los rasgos personales que caracterizan a un líder y las relaciones entre el líder y su grupo.The current times lead to see the boss like an equal, inclusive to criticize it and challenge it. In last years the boss had support and respect and saw you like a superior; now the boss should have the ability in order to manage situations and try to their “employees” appropriately in order to earn their obedience and loyalty so, this is a merit that could only obtain the one that it is leader. We in this article are going to attempt make a brief journey for the different dimension and types of leadership, the common personnels that characterize a leader and the relationships between the leader and their group.Facultad de Educación y Humanidades - Campus de Melilla (Universidad de Granada

Effects of Competitive ELISA-Positive Results of Piroplasmosis on the Performance of Endurance Horses

Endurance is an increasingly popular equestrian sport. However, in southern Europe, there is a high prevalence of horses that are asymptomatic carriers of equine piroplasmosis (EP), a tick-borne disease that could affect their performance. This study aimed to evaluate the impact and influence of EP on the performance of endurance horses. Blood samples were collected from 40 horses in Extremadura, Spain, before and after a race, in different national elite horse endurance competitions. Hematological and biochemical parameters and EP seroprevalence were analysed by competitive enzyme-linked immunosorbent assay. The global seroprevalence of EP was 70%, with 27 horses testing positive for Theileria equi (67.5%) and three (7.5%) for Babesia caballi, with two of these horses (5%) positive for both. Approximately 82.5% of the horses (33 of 40) completed the competition, with no influence on performance or position achieved in those with subclinical parasitosis. There were also no significant differences in hematological or biochemical values between seropositive and seronegative horses. The data suggest that horses without clinical signs of EP can participate without performance impairment in competitions of up to 80 km. Although it is recommended that longer distance competitions should be further evaluated, this is the first step for decision-making by organizers and participants in this sport

West Nile and Usutu virus infections in wild birds admitted to rehabilitation centres in Extremadura, western Spain, 2017-2019

10 Pág. Centro de Investigación en Sanidad Animal (CISA)West Nile virus (WNV) is an emerging flavivirus transmitted generally by mosquitoes of Culex genus. It is maintained in an enzootic life cycle where birds act as reservoir hosts. Humans and horses are also susceptible to infection, and occasionally, they suffer from neurological complications. However, they do not transmit the virus to other vectors, behaving as dead-end hosts. Sporadic WNV outbreaks observed in horses and wild birds from Extremadura (western Spain) during 2016 and 2017 seasons prompted to carry out this survey in wild birds, focused on specimens coming from two wildlife rehabilitation centres. Between October 2017 and December 2019, samples from 391 wild birds, belonging to 56 different species were collected and analysed in search of evidence of WNV infection. The analysis of serum samples for WNV-specific antibodies by ELISA, whose specificity was subsequently confirmed by virus-neutralisation test (VNT) showed positive results in 18.23 % birds belonging to 18 different species. Pelecaniformes (33.33 %), Accipitriformes (25.77 %) and Strigiformes (22.92 %) orders had the higher seroprevalences. Remarkably, WNV-specific antibodies were found in a black stork for the first time in Europe. Analysis by real time RT-PCR in symptomatic birds confirmed the presence of WNV lineage 1 RNA in griffon vulture and little owls. Specificity analysis of ELISA positive and doubtful sera was performed by differential VNT titration against WNV and two other cross-reacting avian flaviviruses found in Spain: Usutu virus (USUV) and Bagaza virus (BAGV). Only four samples showed USUV-specific antibodies (1.04 %) corresponding to three species: Eurasian eagle-owl, griffon vulture and great bustard (first detection in Europe) whereas no samples were found reactive to BAGV. Differential VNT yielded undetermined flavivirus result in 16 samples (4.17 %). This is the first study carried out on wild birds from Extremadura (western Spain). It highlights the widespread circulation of WNV in the region and its co-circulation with USUV.Research funded by Consejería de Economía e Infraestructura of the Junta de Extremadura and the European Regional Development Fund, a Way to Make Europe, through the research project (grant numbers IB16135 and GR18148) and the National Institute for Agricultural and food Research and Technology (INIA-CISA) (grant number E-RTA2015-00002-C02-00)Peer reviewe

Serological evidence of co-circulation of West Nile and Usutu viruses in equids from western Spain

13 Pág. Centro de Investigación en Sanidad Animal (CISA)West Nile virus (WNV) is a mosquito-borne emerging virus in Europe with capacity to cause neurological complications such as encephalitis or meningoencephalitis in humans, birds or equids. In Spain, WNV is actively circulating in mosquitoes, birds and horses in different regions, but never has been deeply studied in Extremadura. Therefore, the aim of this study was to evaluate the seroprevalence of WNV in equids of those areas and to analyse the risk factors associated with exposure to the virus. A total of 199 out of 725 equids presented antibodies against WNV by competition ELISA (27.45%), while 22 were doubtful (3.03%). Anti-WNV IgM antibodies were detected in 16 equids (2.21%), and 3 animals were doubtful (0.41%). All ELISA-reactive positive/doubtful sera (N = 226) were further tested by micro-virus neutralization test (VNT), and a total of 143 horses were confirmed as positive for WNV, obtaining a seroprevalence of 19.72% in equids of western Spain. In addition, specific antibodies against USUV were confirmed in 11 equids. In 24 equids, a specific flavivirus species (detected by ELISA test) could not be determined. The generalized linear mixed-effects models showed that the significant risk factors associated with individual WNV infection in equids were the age (adults) and hair coat colour (light), whereas in USUV infections, it was the breed (pure). Data demonstrated that WNV and USUV are circulating in regions of western Spain. Given the high WNV seroprevalence found in equids from the studied areas, it is important to improve the surveillance programmes of public health to detect undiagnosed human cases and to establish a vaccination programme in equid herds in these regions.This research was supported financially by grant IB16135 funded by the Regional Ministry of Economy and Infrastructure, Extremadura Government and the European Regional Development Fund ‘A way to make Europe’ and grant E-RTA2015-00002-C02-00 funded by INIA.

Desarrollo de material educativo para la difusión de la cristalografía a la sociedad

El Concurso de Cristalización en la escuela se organiza en Madrid desde el año 2014. Sin embargo, valorando las experiencias en conjunto, y teniendo en cuenta que dos de los objetivos principales son fomentar las vocaciones científicas entre los estudiantes preuniversitarios y la divulgación de una disciplina tan desconocida por la sociedad y sin embargo tan necesaria, se pensó en la promoción de una forma más eficaz y directa del Concurso.Depto. de Mineralogía y PetrologíaFac. de Ciencias GeológicasFALSEsubmitte
