    The Serpukhovian coral assemblages from Idmarrach and Tirhela formations (Adarouch, Morocco) have been studied. They yielded quite diverse assemblages with a total of 32 rugose and 1 tabulate species. The distribution of corals in the sections Idmarrach 1, 2, 3, and 4 and Tirhela 1 and 2 has been established, which include Serpukhovian and Bashkirian rocks. The Serpukhovian assemblages are composed mostly of species that have their higher abundance in the upper Viséan. However, most of the recorded taxa in Adarouch have been already mentioned in Serpukhovian rocks from Britain, Moscow Basin, Urals, Donets Basin and other North African regions such as Tindouf and Béchar. Thus, their stratigraphic range is not expanded. The coral diversity is mainly concentrated in biostromes from the Idmarrach 1 section. However, the high total diversity is due to the combination of favourable depositional settings and a mixture in different beds of several ecological environments, such as coral shoals, protected lagoons and microbial mounds. Most Serpukhovian species have been recorded in areas from the western Palaeotethys previously mentioned. The total assemblage can be considered as typical for the late Mississippian in the western Palaeotethys. However, a small degree of isolation is registered by the absence in the Serpukhovian from Adarouch of the genera Lonsdaleia, Actinocyathus, Tizraia and Kizilia that have been recorded in other North African basins. That fact may be explained by the incipient rising of some areas as ‘highs’ due to the start of the collision between Gondwana and Laurasia.Research project CGL2012-30922BTE of the Spanish Ministry of Research and InnovationPeer reviewe

    Se describen los corales rugosos y tabulados de las formaciones Idmarrach y Tirhela, que se localizan en el área de Adarouch, en la Meseta central de Marruecos. Se han identificado 32 especies de corales rugosos pertenecientes a 19 géneros y una especie de coral tabulado. Las asociaciones de edad Serpukhoviense de las formaciones estudiadas están compuestas en su mayoría por especies que tienen su máximo desarrollo en el Viseense superior. Sin embargo, la mayoría de los taxones identificados en Adarouch han sido mencionados previamente en rocas del Serpukhoviense de otras regiones del Paleotethys occidental y las cuencas epicontinentales del norte de África. Las asociaciones de corales están dominadas por corales coloniales pertenecientes a la familia Lithostrotionidae y por corales solitarios pertenecientes a la familia Aulophyllidae. Son también frecuentes los representantes de las familias Axophyllidae, Cyathaxoniidae, Cyathopsidae, Palaeosmiliidae, Stereophrentidae y Zaphrentoididae. El medio de desarrollo de los corales estudiados fue una plataforma carbonatada interna a media con importantes aportes de terrígenos finos.The Serpukhovian coral assemblages from the Idmarrach and Tirhela formations in Central Morocco are described. 32 rugose species belonging to 19 genera and 1 tabulate species have been identified. The Serpukhovian assemblages are composed mostly of species that have their greater abundance in the upper Viséan. However, most recorded taxa in Adarouch have been already mentioned in Serpukhovian rocks from other regions in the Palaeotethys and in North African epicontinental basins. The coral assemblage is dominated by colonial corals belonging to the family Lithostrotionidae and solitary corals belonging to the family Aulophyllidae. In addition, representatives of the families Axophyllidae, Cyathaxoniidae, Cyathopsidae, Palaeosmiliidae, Stereophrentidae and Zaphrentoididae are also present in the assemblages. The environment where the corals lived was mostly an inner to middle carbonate platform with a minor but significant input of terrigenous sediments.Depto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEMinisterio de Ciencia e Innovación (MICINN)pu

    Treatment Options for the Atrophic Posterior Maxilla

    Maxillary sinus augmentation has been shown to be a predictable surgical procedure used to enhance bone volume for the placement of dental implants in the atrophic posterior maxilla. Therefore, various techniques have been proposed in order to achieve the necessary bone dimension for the insertion of implants in previously compromised sites. Careful case and material selection corresponding to different indications can be beneficial to achieving predictable and consistent treatment outcomes in the posterior atrophic maxilla. The purpose of this review was to discuss the indications, contraindications, limitations, and case selection criteria used to determine treatment options for the different techniques. It is necessary to define case selection criteria according to the remaining crestal bone and the anatomy of the sinus cavit

    Background and Aims: Transforming the doctor-patient re lationship from analog to digital is no simple task and requires a great deal of courage and visionary leadership. The first step to do so is to identify the digital capabilities that the ultimate re cipient of every health system possesses: the patient. Methods: A scale questionnaire of 5 questions related to digital applications is carried out to patients under follow-up for type 1 diabetes mellitus, between 18?65 years old, who are prescribed the Abbott Freestyle Libre flash glucose monitoring device, which requires their connection to a mobile application (Libreview) by the user, for optimal use and communication of data with the healthcare professional electronically. Results: 62 patients were included.In the classification by predefined subgroups according to the questionnaire score, 35 patients (56.45%) were identified as having advanced training; 16 (25.81%) of basic training and 11 (17.74%) without digital training. 82.86% (29/35) of the patients predefined as highly qualified used the system adequately, compared to 43.75% (7/16) of those with low training and 0% (0/11) of patients without technological capabilities; p < 0.001. Conclusions: The coronavirus-19 pandemic has subjected our health services to a stress test like never before. In the current remote care scenario, we are presented with an opportunity (the great opportunity) to serve people immersed in the digital age. It would be bad news if after this pandemic, we returned to the starting box, the identification of those e-young and e-senior chronics patients is the first essential step to avoid it.

    Purpose: We present de case of a 27-year-old woman admitted to ICU after scheduled splenectomy to study her short course of fever, leukopenia and splenic space-occupying lesions and splenomegaly. She has been previously treated with Infliximab due to indeterminate colitis and completed correct tuberculosis prophylaxis. Materials and methods: We reviewed our case in our regional Electronic Health DataBase IANUS and compared it with other case reports in literature, found in PubMed, with keywords tuberculosis, inflammatory disease and hemophagocytic lymphohistiocytosis. Results: After splenectomy, she needed intensive care due to acute respiratory failure, alveolar-interstitial pulmonary infiltrates, right pleural effusion and fever. Bone marrow aspirate resulted in hemophagocytic lymphohistiocytosis. Only multidisciplinary management in ICU and combined treatment with chemotherapy for hemophagocytic syndrome and tuberculostatics achieved her curation. Conclusion: Tuberculosis must always be considered in the differential diagnosis of hemophagocytic lymphohistiocytosis and acute respiratory failure despite correct prior prophylaxi

    PRACTICUM DIRECT Simulator for Decision Making during Pandemics

    Presented at the 4th XoveTIC Conference, A Coruña, Spain, 7–8 October 2021[Abstract] The past and current situation of the SARS-CoV-2 pandemic has put the entire society, and especially all hospital systems, worldwide to the test. It is essential that health system managers and decision makers optimize the management of resources, even being forced to improvise new units, divert resources usually destined to other functions and/or change the usual care modality by considerably enhancing aspects of telemedicine. Artificial Intelligence (AI) techniques and procedures are of great help in decision making in emergency environments due to severe pandemics because of their predictive capacity. This paper presents the PRACTICUM DIRECT project, which proposes the design and implementation of a tool to assist health system managers in making decisions on the early management of hospital resources. It makes use of AI techniques to identify the most critical variables in each case and build models capable of showing the possibilities and consequences of the decisions taken on resources at each moment of the emergency. It includes a simulator that shows how they would affect management. The current status is that of the selection of the most appropriate variables, taking into account those affected during the SARS-CoV-2 pandemic: infectious diseases, cardio-neuro-circulatory diseases, metabolic diseases and rehabilitative medicine.This research was funded by the General Directorate of Culture, Education and University Management of Xunta de Galicia “PRACTICUM DIRECT” Ref.

    A new early Visean coral assemblage from Azrou-Khenifra Basin, central Morocco and palaeobiogeographic implications

    Get PDF
    A new early Visean coral assemblage has been recorded from turbidite facies in the southern part of the Azrou-Khenifra Basin, northwest of Khenifra, central Morocco. The newly discovered Ba Moussa West (BMW) coral fauna includes Siphonophyllia khenifrense sp. nov., Sychnoelasma urbanowitschi, Cravenia lamellata, Cravenia tela, Cravenia rhytoides, Turnacipora megastoma and Pleurosiphonella crustosa. The early Visean age of the coral assemblage is supported by foraminiferal and conodont data, with the recognition of the basal Visean MFZ9 Zone. This confirms that the first transgression in the Azrou-Khenifra Basin was during the earliest Visean. The allochthonous coral assemblage was recovered from coarse-grained proximal limestone debris flow and turbidite beds within a fault-bounded unit, lying to the west of a thrust syncline containing upper Visean limestones. No evidence exists of the former early Visean shallow-water platform from which the corals were derived. All other in situ platform carbonate rocks around the southern margin of the Azrou-Khenifra Basin are probably of late Visean (Asbian–Brigantian) age. The early Visean Ba Moussa West coral fauna can be compared with that at Tafilalt in eastern Morocco, as well as in other Saharian basins of Algeria. Many of the genera and species in the Ba Moussa West assemblage are identical to those in NW Europe, with which it must have had marine connections. The new rugose species described, Siphonophyllia khenifrense, is probably endemic to North Africa. Its ecological niche in NW Europe was occupied by S. cylindrica or S. aff. garwoodi
