A Power-Performance Perspective to Multiobjective Electroencephalogram Feature Selection on Heterogeneous Parallel Platforms.

This article provides an insight on the power-performance issues related with the CPU-GPU (Central Processing Unit-Graphics Processing Unit) parallel implementations of problems that frequently appear in the context of applications on bioinformatics and biomedical engineering. More specifically, we analyze the power-performance behavior of an evolutionary parallel multiobjective electroencephalogram feature selection procedure that evolves subpopulations of solutions with time-demanding fitness evaluation. The procedure has been implemented in OpenMP to dynamically distribute either subpopulations or individuals among devices, and uses OpenCL to evaluate the fitness of the individuals. The development of parallel codes usually implies to maximize the code efficiency, thus optimizing the achieved speedups. To follow the same trend, this article extends and provides a more complete analysis of our previous works about the power-performance characteristics in heterogeneous CPU-GPU platforms considering different operation frequencies and evolutionary parameters, such as distribution of individuals, etc. This way, different experimental configurations of the proposed procedure have been evaluated and compared with respect to a master-worker approach, not only in runtime but also considering energy consumption. The experimental results show that lower operating frequencies does not necessarily mean lower energy consumptions since energy is the product of power and time. Thus, we have observed that parallel processing not only reduces the runtime, but also the energy consumed by the application despite a higher instantaneous power. Particularly, the workload distribution among both CPU and GPU cores provides the best runtime and very low energy consumption compared with the values achieved by the same alternatives executed by only CPU threads.

[Spermatic cord leiomyosarcoma. Case report and bibliographic review]. / Leiomiosarcoma de cordón espermático. Aportación de un caso y revisión de la literatura.

OBJECTIVE: To report one new case of paratesticular leiomyosarcoma. METHODS: We describe the case of a 68-year-old male patient consulting for right groin pain over two years with a physical examination corresponding to right inguinal hernia. During surgery for hernia correction a paratesticular mass was discovered. RESULTS: Right radical orchiectomy was performed. After the operation there was a recurrence at the scar which was operated and finally the disease progressed both locally and systemically. CONCLUSIONS: We point out the scarce frequency of this type of tumours. We believe that orchiectomy and excision of the cord is the treatment of choice. The use of adjuvant therapies doesn't influence survival significantly.

[Relationship between male age and semen quality. Experience at the number 14 health-care area of the Valencia health-care agency]. / Relación entre la edad del varón y la calidad del estudio seminal. Experiencia en el área sanitaria 14 de la agencia valenciana de la salud.

OBJECTIVES: Spermatic count and number of mobile forms are two very important parameters for the measurement of spermatic quality by means of sperm analysis. Numerous factors such as obesity, smoking, environment contamination, stress, or age act modifying the sperm fecundation capacity, therefore they interfere in the numbers of this two variables. METHODS: We aim to study the influence of age on semen quality. We studied 156 patients. They were divided into three groups: 20-30 years; 31-40 years; and 40-50 years. A Mackler's camera and a Nikon microscope were used for evaluation. RESULTS: Nonparametric statistical study was performed establishing the relationship between sperm count and mobility and age. Age-count: X2: 8.239 (p = 0.016). Non mobile spermatozoids-age: X2 = 6.871 (p = 0.032). Mobile spermatozoids-age: X2 = 7.378 (p = 0.025). CONCLUSIONS: The age of the patient is intimately related to a decrease of the number of spermatozoids, with the decrease of the number of mobile forms and the increase of the non mobile.

Objetivo: El recuento del número de espermatozoides y del número de formas móviles son dos parámetros muy importantes en la medición de la calidad espermática a través del espermiograma. Numerosos factores como la obesidad, el tabaquismo, la contaminación ambiental, el estrés, o la edad, actúan alterando la capacidad de fecundación del semen y por tanto interfieren en la cuantía de estas dos variables. Métodos: Se pretende estudiar la influencia sobre la calidad del semen de la edad. Se estudiaron un total de 156 pacientes. Los integrantes fueron divididos en tres grupos: 20-30 años; 31-40 años; 40-50 años. Se utilizó una cámara Mackler y un microscopio Nickon. Resultados: Se realizó un estudio estadístico no paramétrico (prueba de Kruskall-Wallis) relacionando las variables recuento espermático y movilidad con la edad. Recuento-edad: X2= 8.239 (p = 0.016). Espermatozoides inmóviles-edad: X2= 6.871 (p = 0.032). Espermatozoides móviles-edad: X2=7.378 (p = 0.025). Conclusiones: La edad del paciente está íntimamente relacionada con la disminución del número de espermatozoides, con la disminución del número de formas móviles y con el aumento de las inmóviles (AU)

[Brucellar orchitis. Case report and bibliographic review]. / Orquitis brucelar. A propósito de un nuevo caso y revisión de la literatura.

OBJECTIVE: We report one case of unilateral epididymo-orchitis secondary to Brucella and perform a bibliographic review. METHODS: We report the case of a 5 1-year-old male with fever, predominantly in the evening hours, over one month associated with a subacute inflammatory process on the right testicle and osteoarticular pain on the left ribs. RESULTS: Treatment was performed with rifampicin 600 mg/day for 45 days and doxicilin 100 mg/12 hours for 45 days. CONCLUSIONS: The brucellar etiology should be taken into consideration in front of an epididymo- orchitis with torpid outcome, mainly in areas of endemic Brucella and patients that have had contact with cattle or non controlled milk derivatives. We emphasize that contact could have been several months before the appearance of clinical epididymoorchitis.

[Inverted papilloma. Report of two cases and bibliographic review]. / Papiloma invertido. Aportación de dos casos y revisión de la literatura.

OBJECTIVE: Inverted papilloma is a rare polypoid lesion of the urothelium, known as a different entity since 1963. Not many more than 100 cases have been published. Although its malignant potential is still unknown, several scientific publications have noted it. METHODS: We report to cases of inverted papilloma and perform a detailed bibliographic review. RESULTS: Both patients were diagnosed by the Pathology Department and entered periodic follow-up visits, being free of recurrence at 24 and 18 months respectively. CONCLUSIONS: The possibility that inverted papilloma is a lesion with malignant potential should be considered in every case, and we suggest that patients with this diagnosis should enter a follow-up protocol like any bladder neoplasia.

[Bladder leiomyoma. Report of two new cases and bibliographic review]. / Leiomioma vesical. A propósito de dos nuevos casos y revisión de la literatura.

OBJECTIVE: Primary mesothelial tumors of the bladder are rare entities, being leiomyoma the most frequent of them. It may grow without any clinical symptoms or with very unspecific ones. METHODS: We report two cases of bladder leiomyoma in 2 patients, and performed a bibliographic review. RESULTS: They were treated by transurethral resection, with an excellent outcome, without incidences over five years of follow-up. CONCLUSIONS: Surgical treatment continues to be the best solution; it is easy to perform and has a very limited number of complications. Prognosis is good in any case and progression is anecdotic.
