Motor speed predicts stability of cognitive deficits in both schizophrenic and bipolar I patients at one-year follow-up
J. Salazar-Fraile,V. Balanzá-Martínez,G. Selva-Vera,A. Martínez-Aran
The European Journal of Psychiatry , 2009,
Abstract: Background: We examined whether motor speed assessed by the finger tapping test predicts generalized and specific stable deficits because of a common pathogenic process in bipolar and schizophrenic patients. Methods: One hundred and two patients underwent a battery of neuropsychological tests. Patients with a score of less than one standard deviation from their siblings', sample in two assessments with an interval of one year were defined as suffering from stable deficits because of a common pathogenic process. In addition to univariate analyses, factor analyses, ordinal logistic regression, and multiple linear regressions were used. A general score was also calculated. Results: No differences were found between schizophrenic and bipolar patients in the deficits of verbal fluency, shift reasoning ability and executive attention. Schizophrenic patients had greater persistent cognitive deficit because of a common pathogenic factor in the verbal memory dimension than bipolar patients. Motor speed predicted the specific deficits of verbal fluency, shift reasoning, executive attention and the general deficit of both bipolar I and schizophrenic patients. Bipolar patients suffered a lesser specific deficit in the verbal memory dimension than schizophrenic patients did, this domain not being predicted by motor speed. Motor speed predicted the generalized deficit and the specific dimensions in which schizophrenic and bipolar patients showed no differences. Conclusions: These results suggest the presence of general and specific stable cognitive deficits because of a common pathogenic factor related to psychomotor slowness. Motor speed seems to be suitable endophenocognitype for schizophrenia and bipolar disorder.

Validity and reliability of the Functioning Assessment Short Test (FAST) in bipolar disorder
Rosa Adriane R,Sánchez-Moreno Jose,Martínez-Aran Anabel,Salamero Manel
Clinical Practice and Epidemiology in Mental Health , 2007, DOI: 10.1186/1745-0179-3-5
Abstract: Background Numerous studies have documented high rates of functional impairment among bipolar disorder (BD) patients, even during phases of remission. However, the majority of the available instruments used to assess functioning have focused on global measures of functional recovery rather than specific domains of psychosocial functioning. In this context, the Functioning Assessment Short Test (FAST) is a brief instrument designed to assess the main functioning problems experienced by psychiatric patients, particularly bipolar patients. It comprises 24 items that assess impairment or disability in six specific areas of functioning: autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relationships and leisure time. Methods 101 patients with DSM-IV TR bipolar disorder and 61 healthy controls were assessed in the Bipolar Disorder Program, Hospital Clinic of Barcelona. The psychometric properties of FAST (feasibility, internal consistency, concurrent validity, discriminant validity (euthymic vs acute patients), factorial analyses, and test-retest reliability) were analysed. Results The internal consistency obtained was very high with a Cronbach's alpha of 0.909. A highly significant negative correlation with GAF was obtained (r = -0.903; p < 0.001) pointing to a reasonable degree of concurrent validity. Test-retest reliability analysis showed a strong correlation between the two measures carried out one week apart (ICC = 0.98; p < 0.001). The total FAST scores were lower in euthymic (18.55 ± 13.19; F = 35.43; p < 0.001) patients, as compared with manic (40.44 ± 9.15) and depressive patients (43.21 ± 13.34). Conclusion The FAST showed strong psychometrics properties and was able to detect differences between euthymic and acute BD patients. In addition, it is a short (6 minutes) simple interview-administered instrument, which is easy to apply and requires only a short period of time for its application.
Combination Antifungal Therapy in the Treatment of Scedosporium apiospermum Central Nervous System Infections
Andrés F. Henao-Martínez,José R. Castillo-Mancilla,Michelle A. Barron,Aran Cunningham Nichol
Case Reports in Infectious Diseases , 2013, DOI: 10.1155/2013/589490
Abstract: Treatment of Scedosporium apiospermum central nervous system (CNS) infection typically consists of an azole in combination with surgical debridement. This approach requires prolonged treatment and carries a high associated mortality. We present two cases of the successful treatment of S. apiospermum CNS infections with the combination of voriconazole and terbinafine. 1. Case Reports 1.1. Case??1 An 81-year-old Hispanic woman with a past medical history significant for hypertension, diabetes mellitus, hypothyroidism, and chronic kidney disease presented with symptoms of sinusitis, including facial pain, nasal congestion, and rhinorrhea. The sinusitis was later complicated by the development of left orbital cellulitis. The patient underwent a functional endoscopic sinus surgery (FESS) without evidence of gross infection and was treated with oral levofloxacin. Three weeks later, her orbital cellulitis resolved; however, she developed nausea, vomiting, headaches, left vision loss, diplopia, and local pain. Her eye exam was significant for intact extraocular movements, no nystagmus, and a positive afferent pupillary defect. No periorbital edema or erythema was observed. Visual acuity for her right eye was 20/60 and for her left eye was 20/100. Her basic laboratory results were normal. She was diagnosed with a left orbital complex syndrome with optic neuropathy and underwent another FESS with sinusotomy and debridement. The patient was briefly placed on intravenous (IV) steroids, and she was discharged home on an oral prednisone taper and levofloxacin. However, the patient was readmitted 10 days later with worsening vision loss on the left; she was then only able to perceive light. The intraoperative cultures from her last FESS grew a moderate amount of mold, which was subsequently identified as Scedosporium apiospermum based on its characteristic macroscopic morphology and conidiation. Susceptibility testing of the isolate revealed a voriconazole MIC of 0.5?ug/mL. An orbital MRI revealed mildly elevated signal within the intraorbital segment of the left optic nerve, mild inflammatory changes surrounding the optic nerve sheath complex and the orbital apex, and very mild asymmetric prominence of the left extraocular muscles concerning for myositis (Figure 1). The patient was placed on IV voriconazole at 6?mg/kg every 12 hours for a presumed fungal sinusitis, myositis, and possibly sinus fungal osteomyelitis. After approximately 30 days of IV voriconazole therapy, the patient was transitioned to oral voriconazole and had obtained a voriconazole trough level of
Organización del Espacio en una Villa-Fortaleza: Aledo, Encomienda Santiaguista en la Frontera Murciano-Granadina en la Transición del Medievo a la Modernidad
Martínez Martínez,María;
Cuadernos de historia de Espa?±a , 2005,
Abstract: historical development of the "encomienda santiaguista" of aledo during the late medieval period. this fortress-village, placed on the front line of the murcia-granada border, consolidated a defensive system that will lose its reason to exist after the conquest of granada in 1492. the "libro de visitas de la orden de santiago" of 1511 and archeological interventions allow the reconstruction of the morphology of the village and of the religious, military and economic spaces of the collective development of this micro-society, which suffered the historical transformations produced during the transition from medieval to modern times.
EL USO DE INDICADORES DE DESEMPE O NORMALIZADOS PARA LA VALORACIóN DE JUGADORES: EL CASO DE LAS ESTADíSTICAS POR MINUTO EN BALONCESTO
J. A. Martínez,L. Martínez
Motricidad : European Journal of Human Movement , 2010,
Abstract: RESUMEN Esta investigación somete a prueba la hipótesis subyacente al uso de indicadores normalizados por minuto en baloncesto: No existe asociación entre los índices normalizados y los minutos jugados por cada jugador. Esa asunción es básica para la comparación de jugadores con índices normalizados, ya que si existe algún tipo de relación funcional entre el ratio normalizado y los minutos jugados, existiría un sesgo en las clasificaciones realizadas en cada apartado estadístico, ya que esa normalización quedaría desvirtuada. Para ello, aplicamos varios métodos hasta ahora no utilizados en el estudio de este tema, como el análisis de la variabilidad intra-jugador y los modelos de ecuaciones estructurales. Los resultados de varios análisis de naturaleza confirmatoria y exploratoria muestran que no existe una asociación lineal relevante entre los minutos jugados y las diferentes categorías normalizadas por minuto: puntos, rebotes, asistencias, recuperaciones y tapones. Las consecuencias relacionadas con el rendimiento deportivo y el marketing son discutidas. De este modo, esta investigación contribuye de forma novedosa a la pujante línea de investigación relacionada con la investigación científica en baloncesto. Palabras Clave: normalización, baloncesto, desempe o, estadísticas ABSTRACT This research empirically tests the hypothesis underlying the use of performance indicators in basketball, when they are normalized using the “per-minute” criterion: There is no association among normalized indicators and the minutes played by each player. This assumption is a necessary requirement in order to compare players using normalized indicators, because if this assumption is not met, then there would be a possible bias in the rankings of each statistical category. We apply several under-used methods in this type of research, such as the analysis of the intra-player variability and the structural equation modelling. Results show that there is no lineal association between the minutes played and the different per-minute normalized categories as: points, rebounds, assists, steals, and blocks. We discuss implications for sport performance and marketing. Therefore, this study contributes to the advance in one of the growing areas of sports research; such as basketball metrics. Key Words: normalization, basketball, performance, statistics
LAS ACTITUDES HACIA EL SERVICIO DEPORTIVO VARíAN SEGúN EL GRADO DE EXPERIENCIA DEL CONSUMIDOR?
J. A. Martínez,L. Martínez
Motricidad : European Journal of Human Movement , 2010,
Abstract: RESUMEN Esta investigación ha analizado si las evaluaciones del consumidor de un servicio deportivo, manifestadas en su grado de satisfacción y calidad percibida, difieren en función del nivel de experiencia en el servicio. Para ello, hemos realizado tres estudios de naturaleza transversal sobre diferentes muestras de consumidores en un servicio deportivo. Los resultados indican que los consumidores noveles ajustan sus expectativas de la misma forma que lo hacen los consumidores con más experiencia en el servicio. Existen diferencias entre la calidad percibida y la satisfacción, porque el consumidor admite que puede estar muy satisfecho sin que el servicio sea el más excelente, siendo ambas actitudes muy positivas. Esas actitudes no difieren en función del nivel de experiencia, porque los consumidores noveles no se crean unas expectativas ilusorias sobre el servicio que van a recibir. El trabajo concluye con la discusión de las implicaciones de estos resultados. Palabras Clave:Experiencia del consumidor; calidad percibida; satisfacción; servicios deportivos. ABSTRACT This research has analysed if consumer evaluations of a sports service, manifested by satisfaction and perceived quality, differ to the extent that consumer experience varies. For that purpose, we have achieved three cross-sectional studies on different samples of users of a sports centre. The results show that newer and more experienced customers adjust their expectations in the same way. In addition, perceived quality and satisfaction differs because customers admit that they can be very satisfied with a service, although the service does not reach the highest level of excellence. Moreover, both attitudes are very positive. Satisfaction and quality do not depend on experience, because newer customers do not create illusory expectations about the service. Finally, implications and limitations are discussed. Key Words: Consumer experience; perceived quality; satisfaction; sports services.
Oligarquía y cultura religiosa: los Puxmarín murcianos y el Estudio de Lleida
Martínez Martínez, María
Anuario de Estudios Medievales , 2003,
Abstract: In this article we approach the analysis and reconstruction of the Puxmarin lineage, which originated in Barcelona and settled in Murcia in the 14 th Century. This lineage is notorious for the high socio-economic status of its members-linked to the urban oligarchy-and specially of Pedro Puxmarin, who in 1504 was in charge of financing the tuiton at the Estudio de Lerida (Lerida University), the institution in which the chaplain-to-be of his private chapel were educated. Análisis y reconstrucción del linaje de los Puxmarín, procedente de Barcelona y asentado en Murcia en el siglo XIV. Destaca el ascenso socioeconómico de sus miembros, vinculados a la oligarquía urbana, y sobre todo de Pedro de Puxmarín, quien financiaba en 1504 la ense anza en el Estudio de Lleida a los futuros capellanes de su capilla privada.
A stakeholder assessment of basketball player evaluation metrics
JOSE A. MARTíNEZ,LAURA MARTíNEZ
Journal of Human Sport and Exercise , 2011,
Abstract: In this research we examined the opinions of basketball stakeholders regarding several questions of special interests to valuate players. Players, coaches, agents, journalists, editors, bloggers, researchers, analysts, fans and chairs participated in this macro-research. After analysing their opinions using the content analysis methodology, we found that current player evaluation systems are insufficient to fulfill the expectations of stakeholders regarding the definition of value, because they fail to rate intangibles. In addition, the importance of qualitative thinking is prominent and should be considered in valuating such intangibles. The current system of valuation used in Euroleague and Spanish ACB League (Ranking) is acknowledged as deficient, but stakeholders think that other advanced metrics do not significantly outperform Ranking. Implications for management, decision making and marketing in basketball are finally discussed.
Capitalizing on the advantages of the Latin American EAP situation: Using authentic and specific materials in EAP writing instruction
Iliana A. Martínez
Ibérica , 2011,
Abstract: This paper describes a situation that suggests an optimistic future for periphery scholars, particularly from Latin America. First it shows a positive evolution of publications in English in Latin America, which appears to be associated to the concomitant evolution of postgraduate programmes. Then, it is argued that such evolution could be improved by a form of EAP instruction that capitalizes on the special characteristics of the Latin American situation, particularly the highly specific needs of learners, the common Latinate L1, the possibility of having homogeneous groups in terms of fields, and the limited set of genres used by researchers in this context. Such features could be exploited to the learners’ advantage through the use of authentic and specific materials. Both authenticity and specificity will increase motivation and reduce comprehension problems, while allowing participants to contribute their knowledge of science to the course.
