Abstract:

In Spain, certain population-based studies have shown high blood mercury (Hg) levels due to the high consumption of fish. Some studies have stated that one of the most consumed fish in Spain is canned tuna. Different Spanish organisms consider that it is safe to consume canned tuna as it supposedly has a low mercury content, particularly in so-called light tuna. However, in Spain light tuna is mainly yellowfin and bigeye tuna, while in other countries it is mainly skipjack tuna. This study analyzed 36 cans of the most popular brands in Spain and examined the influence of the type of tuna, packaging medium (olive oil, sunflower seed oil, water or marinade), different brands, prices and expiration dates. Mercury concentrations (mg/kg) were measured by atomic absorption spectrometry and thermal decomposition amalgamation. The medians observed were (mg/kg): light tuna: 0.314; IQR: 0.205 - 0.594, white tuna: 0.338; IQR: 0.276 - 0.558, skipjack: 0.311; IQR: 0.299 - 0.322, frigate tuna: 0.219; IQR 0.182 - 0.257 and mackerel: 0.042; IQR 0.029 - 0.074. We found statistically significant differences between white tuna, light tuna and mackerel (p = 0.004); light tuna and mackerel (p = 0.002) and white tuna and mackerel (p = 0.006). However, we found no differences between white tuna and light tuna, or among packaging medium, brands, prices or expiration dates. The limit of 0.500 mg/kg of mercury in canned tuna was exceeded by the following percentages of the cans: 33.3% of light tuna, 16.7% of white tuna, and 0% of Skipjack, frigate tuna and mackerel. The mercury content of the cans of Spanish light tuna that were analyzed was variable and high. The results of this study indicate that stricter regulation of Hg in canned tuna is necessary. Until then, it is safer to recommend that vulnerable populations such as children and pregnant women consume canned mackerel, which has a markedly lower mercury content.

Abstract: background. fasciotomy is the core intervention to treat established compartment syndrome, however the ideal intervention would be one able to prevent is occurrence. fasciotomy can also be performed as a prophylactic procedure for compartment syndrome, considered by some to be the best option; but other authors consider it unjustifiable because it is not void of complications. we studied and analyzed the available evidence for the possible indications for prophylactic fasciotomy. materials and methods. we performed a literature search following the bestbet methodology, identifying studies that could determine the impact of prophylactic fasciotomy and risk factors for possible complications. the articles were reviewed according to the strobe critical appraisal criteria. results. four retrospective observational studies were identified, three of them identified risk factors for prophylactic fasciotomy and its impact, while the other related to the identification of risk factors. the most common localization was the leg (68.4%), the clinical scenarios with the highest risk for compartment syndrome were combined arterial and venous vascular trauma (41.8%, or 3.0, ic 1,4-6.1), vascular trauma (arterial 27.2% or 10.4 ic 7.1-15.4, venous 23.4% or 7.4 ic 4.5-12.4), bone fracture with associated with vascular trauma (44% vs. 19%) and dislocation associated to vascular trauma (10.4% or 3,5 ic 1.8-6.8). the risk increases significantly with popliteal vascular trauma, open fractures, proximal tibial fractures, and if knee dislocation occurs. there is no solid evidence to determine that ischemia time, hemorrrhage or the need for blood transfusion act as predictors for the need of fasciotomies. conclusion. the decision to perform prophylactic fasciotomy is difficult, but in some cases of trauma with high risk of a compartment syndrome as: combined or simple vascular injury (mainly popliteal vessels), with or without fracture (mainly proximal tibia) or dislocation (especially knee
Fasciotomía profiláctica y síndrome "compartimental" de las extremidades: existen indicaciones justificables? Prophylactic fasciotomy and compartment syndrome of the extremities: are there justifiable indications?

Revista Colombiana de Cirugía , 2011,
Abstract: Introducción. La fasciotomía es la principal intervención para tratar el síndrome "compartimental"; no obstante, sería ideal prevenir su aparición. El mismo procedimiento quirúrgico, pero profiláctico, se plantea como la mejor opción, aunque para algunos autores su uso puede no ser justificable, debido a que no es un procedimiento inocuo. Se estudió la información disponible para determinar las posibles indicaciones de la fasciotomía profiláctica. Materiales y métodos. Se hizo una búsqueda en la literatura científica, según la metodología BestBETs, para identificar los estudios que determinaran el impacto de la fasciotomía profiláctica o los factores predictores de riesgo. Los artículos se revisaron con la guía STROBE y se extrajeron los datos, previa evaluación de la validez. Resultados. Se identificaron cuatro estudios observacionales retrospectivos; tres de ellos hacen referencia a la predicción de la necesidad de fasciotomías y uno, a la determinación de los factores de riesgo. La localización más frecuente fue la pierna (68,4%) y los factores de mayor riesgo para el síndrome "compartimental" y, por ende, predictores de la necesidad de fasciotomías fueron, en su orden: el trauma vascular combinado (41,8%, OR=3,0; IC95% 1,4-6,1), el trauma vascular no combinado (arterial, 27,2%, OR=10,4; IC95% 7,1-15,4; venoso, 23,4%, OR=7,4%; IC95% 4,5-12,4), la fractura asociada a trauma vascular (44% vs. 19%) y la luxación asociada a trauma vascular (10,4%, OR=3,5; IC95% 1,8-6,8). El riesgo aumenta significativamente cuando el trauma vascular es poplíteo, cuando la fractura es abierta o en tibia proximal, y cuando la luxación es de rodilla. No hay hallazgos concluyentes para catalogar el tiempo de isquemia, la hemorragia o la necesidad de transfusión de hemoderivados como factores predictores de la necesidad de fasciotomías. Conclusión. Es difícil tomar la decisión de realizar una fasciotomía profiláctica, pero en algunos casos de trauma con un riesgo alto de síndrome "compartimental", como una lesión vascular combinada -principalmente, de vasos poplíteos-, con fractura o sin ella -principalmente, de tibia proximal- o luxación -principalmente, de rodilla-, hacen pensar que dicha intervención es recomendable. Las consecuencias de un síndrome "compartimental" en curso son más graves que las de una fasciotomía profiláctica innecesaria. Background. Fasciotomy is the core intervention to treat established compartment syndrome, however the ideal intervention would be one able to prevent is occurrence. Fasciotomy can also be performed as a prophylactic procedure for compa

Automatic Transcription of Flamenco Singing from Polyphonic Music Recordings
Nadine Kroher,Emilia Gómez
Computer Science , 2015,
Abstract: Automatic note-level transcription is considered one of the most challenging tasks in music information retrieval. The specific case of flamenco singing transcription poses a particular challenge due to its complex melodic progressions, intonation inaccuracies, the use of a high degree of ornamentation and the presence of guitar accompaniment. In this study, we explore the limitations of existing state of the art transcription systems for the case of flamenco singing and propose a specific solution for this genre: We first extract the predominant melody and apply a novel contour filtering process to eliminate segments of the pitch contour which originate from the guitar accompaniment. We formulate a set of onset detection functions based on volume and pitch characteristics to segment the resulting vocal pitch contour into discrete note events. A quantised pitch label is assigned to each note event by combining global pitch class probabilities with local pitch contour statistics. The proposed system outperforms state of the art singing transcription systems with respect to voicing accuracy, onset detection and overall performance when evaluated on flamenco singing datasets.

Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.32034
Abstract: The Scab of purple passion fruit or gulupa (Passiflora edulis Sims.) is a serious disease, affecting all aerial organs of the plant, but also to reducing the visual quality of the fruits, which reduces export production. To determine the primary causal agent of disease in Colombia, associated microorganisms were isolated from scab lesions on stems, leaves, flowers and fruits, recovering in PDA. Obtaining Cladosporium, Colletotrichum and Botrytis. Cladosporium had the highest frequency of fungal isolates. 15 strains were evaluated for their pathogenicity on fruits and leaves of gulupa in laboratory and greenhouse conditions. 9 strains caused symptom expression at 95% humidity and 17°C - 20°C, validating Cladosporium as causal agent of gulupa scab. For those pathogenic strains, were determinate incubation and latency periodsin leaves (7 - 11 and 8 - 12 DPI) and fruits (6 - 10 and 8 - 12 DPI) revealing differences or virulence levels in the pathogen populations.
