    A new ghost shrimp, Vulcanocalliax arutyunovi n.gen. n.sp., is described and accommodated in the new subfamily Vulcanocalliacinae. This subfamily shares with the Bathycalliacinae Sakai & Turkay, 1999 the presence of epipods on the third maxilliped and the first four pairs of pereopods, but differs by the absence of cardiac sulci and a dorsomedian carina. This is the second record of a thalassinidean crustacean from deep-sea chemoautotrophic communities.Training Through Research Programme IOC-UNESCOEC FP6 - GOCE-CT-2005-511234 HERME

    The occurrence of Natsushima bifurcata (Polychaeta : Nautiliniellidae) in Acharax hosts from mud volcanoes in the Gulf of Cadiz (south Iberian and north Moroccan Margins)

    Get PDF
    Fifteen specimens of nautiliniellid polychaetes were found in the mantle cavity of bivalves of the genus Acharax (Solemyidae) collected in several mud volcanoes from the Gulf of Cadiz. They were identified as Natsushima bifurcata Miura and Laubier (1990), a species previously known only from Sagami Bay (Japan). The morphological comparison of these specimens with the holotype suggests that they belong to the same morphological species, although further studies should consider whether they could be genetically different. The ecology of the species is discussed in relation to the available information on the family. The occurrence of Natsushima bifurcata in the Gulf of Cadiz is the first record of the species in the North Atlantic.EC FP6 - GOCE-CT-2005-511234 HERMESTraining Through Research Programme, IOC-UNESC

    Tubiclavoides striatum gen. nov et sp nov (Cnidaria : Hydrozoa) a new bathyal hydroid from the Gulf of Cadiz, north-east Atlantic Ocean

    Get PDF
    Tubiclavoides striatum, a new species of an athecate hydroid, was found on mud volcanoes, inactive carbonate clumneys, and cold-water coral stands in the Gulf of Cadiz (south-western Iberian Peninsula, Atlantic Ocean). The new family Tubiclavoididae and the new genus Tubiclavoides are proposed to accommodate the new species. The new hydroid is characterized by scattered filiform tentacles, sporosacs developing among the tentacles and hydrocauli covered with striated perisarc, often subdivided into imbricating cones. A full description and illustrations are provided, as well as some notes on the ecology and distribution of the new species

    Are organic falls bridging reduced environments in the deep sea?: Results from colonization experiments in the Gulf of Cadiz

    Get PDF
    Organic falls create localised patches of organic enrichment and disturbance where enhanced degradation is mediated by diversified microbial assemblages and specialized fauna. The view of organic falls as “stepping stones” for the colonization of deep-sea reducing environments has been often loosely used, but much remains to be proven concerning their capability to bridge dispersal among such environments. Aiming the clarification of this issue, we used an experimental approach to answer the following questions: Are relatively small organic falls in the deep sea capable of sustaining taxonomically and trophically diverse assemblages over demographically relevant temporal scales Are there important depth- or site-related sources of variability for the composition and structure of these assemblages? Is the proximity of other reducing environments influential for their colonization? We analysed the taxonomical and trophic diversity patterns and partitioning (α- and β-diversity) of the macrofaunal assemblages recruited in small colonization devices with organic and inorganic substrata after 1-2 years of deployment on mud volcanoes of the Gulf of Cádiz. Our results show that small organic falls can sustain highly diverse and trophically coherent assemblages for time periods allowing growth to reproductive maturity, and successive generations of dominant species. The composition and structure of the assemblages showed variability consistent with their biogeographic and bathymetric contexts. However, the proximity of cold seeps had limited influence on the similarity between the assemblages of these two habitats and organic falls sustained a distinctive fauna with dominant substrate-specific taxa. We conclude that it is unlikely that small organic falls may regularly ensure population connectivity among cold seeps and vents. They may be a recurrent source of evolutionary candidates for the colonization of such ecosystems. However, there may be a critical size of organic fall to create the necessary intense and persistent reducing conditions for sustaining typical chemosymbiotic vent and seep organisms

    The Montreal Cognitive Assessment (MoCA) as a screening test for cognitive dysfunction in multiple sclerosis

    This study investigates the utility of the Portuguese version of Montreal Cognitive Assessment (MoCA) as a screening-method for identifying cognitive dysfunction (CD) in multiple sclerosis (MS). The 118 participants with comprehensive neuropsychological assessment were divided into two subgroups: (I) MS group (n = 59) and (II) control group (n = 59). The MS patients were classified as cognitively intact (n = 26) or impaired (n = 33, 56%). The results indicated that the MoCA is a psychometrically valid instrument in assessment of MS patients. The Multiple Linear Regression analyses highlighted the significant influence of Modified Fatigue Impact Scale and Irregular Word Reading Test on MoCA performance. The MoCA total score showed a good discriminative capacity between cognitively impaired and cognitively intact subjects. In addition, there were significant differences in MoCA cognitive domain scores between groups. The MoCA total score cut-off point for identifying CD in MS patients was a score below 26 points (AUC = 0.837, CI = 0.736-0.937). A proposed EM-MoCA-Subscore for identifying the MS-related cognitive impairment (max. score = 19 points, cut-off <17 points, AUC = 0.871, CI = 0.784-0.958), can reduce administration time for cognitive screening in clinical settings. The MoCA is a useful and sensitive instrument to identify the MS-related cognitive impairment.info:eu-repo/semantics/publishedVersio

    BACKGROUND: In Mozambique, the prevalence of malaria in children under 5 years of age is among the highest in the world, but limited data exist on determinants of care-seeking behaviour for malaria. This study aimed at determining the trends and factors associated with care-seeking behaviour for fever among children under 5 years of age and to assess the treatment practices for malaria. METHODS: Secondary data analysis of two cross-sectional studies. Descriptive statistics were used to summarize socio-economic and demographic characteristics of participants, using data from the 2011 Demographic and Health Survey and 2015 Indicators of Immunization, Malaria and HIV/AIDS Survey. Complex sampling logistic regression model was used to identify factors associated with care-seeking behaviour, with estimated adjusted odds ratio and respective 95% confidence intervals, only for 2015 IMASIDA data. RESULTS: A total of 10,452 and 5168 children under 5 years of age were enrolled in the 2011 DHS and 2015 IMASIDA, respectively. Care-seeking for fever in public and private sectors remained stable during this period (62.6%; 835/1432 in 2011 and 63.7%; 974/1529 in 2015). The main place where care was sought in both surveys was public hospitals (86.2%; 773/897 in 2011 and 86.7%; 844/974 in 2015). Prescription of anti-malarial drugs increased from 42.9% (385/897) in 2011 to 53.8% (524/974) in 2015. Artemether-lumefantrine was the most used anti-malarial drug for febrile children in both surveys and its use increased from 59.0% (219/373) in 2011 to 89.3% (457/512) in 2015. Data from 2015 elucidated that care-seeking was more common in children whose mothers had a secondary level of education (AOR = 2.27 [95% CI 1.15-4.49]) and among those in poorer quintile (AOR = 1.46 [95% CI 0.83-1.90]). Mothers with higher education level (AOR = 0.16 [95% CI 0.34-0.78]) were less likely to seek out care. People from Manica (AOR = 2.49 [1.03-6.01]), Sofala ([AOR = 2.91 [1.03-8.24]), Inhambane (AOR = 3.95 [1.25-12.45]), Gaza (AOR = 3.25 [1.22-8.65]) and Maputo Province (AOR = 2.65 [1.10-6.41]) were more likely to seek care than people from Maputo City. CONCLUSION: Data from this study showed that care-seeking in Mozambique remained suboptimal. Interventions to raise the awareness for early care-seeking during episodes of fever should be urgently reinforced and intensified.publishersversionpublishe

    Feohifomicosis Producida por Alternaria Infectoria con Presentación Clínica de Múltiples Lesiones Vegetantes en un Paciente Sometido a un Trasplante Renal

    Get PDF
    The genus Alternaria is one of the most common black moulds and appears to be increasing as a causative agent of subcutaneous phaeohyphomycosis, particularly among immunosuppressed patients. A 53-year-old patient who had received a kidney transplant presented with multiple verrucous lesions on the distal extremities. Positive histopathology and cultures, in addition to rDNA ITS region sequencing, identified the fungal isolate as Alternaria infectoria. Oral itraconazole was administered for 10 months. A follow-up at 15 months demonstrated no signs of infection. Clinical manifestations of cutaneous alternariosis vary significantly and only a few cases have been described in the literature. Although optimal treatment options remain controversial, this case of phaeohyphomycosis was successfully treated with itraconazole monotherapy
