Lesiones del labrum acetabular. Etiología, lesiones artroscópicas e indicaciones de tratamiento

En la última década se ha experimentado un notable incremento en el número de cirugías artroscópicas de cadera realizadas en nuestros hospitales. Las lesiones de labrum acetabular son probablemente la principal causa por la que un cirujano ortopédico realiza una artroscopia de cadera. El objetivo del siguiente artículo es revisar las diferentes lesiones del labrum que podemos encontrarnos en la práctica diaria y atendiendo a los cambios anatomopatológicos que se han producido. Esto nos va a permitir entender de manera global cuál es el problema fundamental al que nos enfrentamos cuando tratamos a pacientes con dolor inguinal y lesiones del labrum acetabular, y así poder elegir la mejor estrategia terapéutica. Se describen de forma superficial las diferentes opciones terapéuticas, sin profundizar en ellas, puesto que no es el objetivo de la presente revisiónDuring the last decade, an increasing rate in the number of hip arthroscopies has been experienced in our hospitals. Acetabular labrum injuries are likely the main cause by which an orthopedic surgeon perform a hip arthroscopy. The objective of the following paper is to review the different labral injuries we can find in our daily practice and indentify the its anatomopathological changes. This is going to let us know, in a global way, which is the main problem we are facing when we are treating patients with groin pain and acetabular labral injuries, and then we can choose the best treatment option. Different treatment options are superficialy described, becaus it’s not the objective of this revie

Assessment of natural radioactivity levels and radiation exposure in new building materials in Spain

Novel building materials were manufactured and analyzed for 226Ra, 232Th and 40K using an HPGe gamma-ray spectrometer. The results show that the highest value of 40K was 4530 Bq per kg which was measured in a sample containing fly ashes from olive stones. The highest values of 226Ra and 232Th activities were 181 and 185 Bq per kg, which were measured in a sample with fly ashes from the co-combustion of coal and coke, respectively. On the other hand, the lowest values of 40K, 226Ra and 232Th activities were obtained for samples incorporating mussel shells. The radiological health hazard parameters, such as radium equivalent activity (Raeq), activity concentration index (I), absorbed and effective dose rates, associated with these radionuclides were evaluated. These values are within the EU recommended limits in building materials, except for samples of concrete containing fly ashes from olive stones, coal and coke. This study has contributed to the inclusion of industrial wastes that have not been collected previously in the Naturally Occurring Radioactive Material (NORM) databases on radioactivity of building materials

Isomeric carbazolocarbazoles: synthesis, characterization and comparative study in Organic Field Effect Transistors

We report here the synthesis and characterization of a new family of isomeric carbazolocarbazole derivatives, namely carbazolo[1,2-a]carbazole, carbazolo[3,2-b]carbazoleand carbazolo[4,3-c]carbazole. Thermal, optical, electrochemical, morphological and semiconducting properties have been studied to understand the influence of geometrical isomerism on the optoelectronic properties of these compounds. Different packing patterns have been observed by single crystal X-ray diffraction (XRD) which then correlate with the different morphologies of the evaporated thin films studied by XRD and Atomic Force Microscopy (AFM). The effect of N-substituents has also been evaluated for one of the isomers revealing a noticeable influence on the performance as organic semiconductors in Organic Field Effect Transistors (OFETs). A good p-channel field effect has been determined for N,N′-dioctylcarbazolo[4,3-c]carbazole with a mobility of 0.02 cm2 V−1 s−1 and Ion/Ioff ratio of 106 in air. These preliminary results demonstrate the promising properties of molecular carbazolocarbazole systems which should be further explored in the area of organic semiconducting materials

Body weight distortions in an auditory-driven body illusion in subclinical and clinical eating disorders.

Previous studies suggest a stronger influence of visual signals on body image in individuals with eating disorders (EDs) than healthy controls; however, the influence of other exteroceptive sensory signals remains unclear. Here we used an illusion relying on auditory (exteroceptive) signals to manipulate body size/weight perceptions and investigated whether the mechanisms integrating sensory signals into body image are altered in subclinical and clinical EDs. Participants' footstep sounds were altered to seem produced by lighter or heavier bodies. Across two experiments, we tested healthy women assigned to three groups based on self-reported Symptomatology of EDs (SED), and women with Anorexia Nervosa (AN), and used self-report, body-visualization, and behavioural (gait) measures. As with visual bodily illusions, we predicted stronger influence of auditory signals, leading to an enhanced body-weight illusion, in people with High-SED and AN. Unexpectedly, High-SED and AN participants displayed a gait typical of heavier bodies and a widest/heaviest visualized body in the 'light' footsteps condition. In contrast, Low-SED participants showed these patterns in the 'heavy' footsteps condition. Self-reports did not show group differences. The results of this pilot study suggest disturbances in the sensory integration mechanisms, rather than purely visually-driven body distortions, in subclinical/clinical EDs, opening opportunities for the development of novel diagnostic/therapeutic tools

Phage inducible islands in the gram-positive cocci

The SaPIs are a cohesive subfamily of extremely common phage-inducible chromosomal islands (PICIs) that reside quiescently at specific att sites in the staphylococcal chromosome and are induced by helper phages to excise and replicate. They are usually packaged in small capsids composed of phage virion proteins, giving rise to very high transfer frequencies, which they enhance by interfering with helper phage reproduction. As the SaPIs represent a highly successful biological strategy, with many natural Staphylococcus aureus strains containing two or more, we assumed that similar elements would be widespread in the Gram-positive cocci. On the basis of resemblance to the paradigmatic SaPI genome, we have readily identified large cohesive families of similar elements in the lactococci and pneumococci/streptococci plus a few such elements in Enterococcus faecalis. Based on extensive ortholog analyses, we found that the PICI elements in the four different genera all represent distinct but parallel lineages, suggesting that they represent convergent evolution towards a highly successful lifestyle. We have characterized in depth the enterococcal element, EfCIV583, and have shown that it very closely resembles the SaPIs in functionality as well as in genome organization, setting the stage for expansion of the study of elements of this type. In summary, our findings greatly broaden the PICI family to include elements from at least three genera of cocci

Compromised Phagosome Maturation Underlies RPE Pathology in Cell Culture and Whole Animal Models of Smith-Lemli-Opitz Syndrome

Treatment of rats with the cholesterol pathway inhibitor AY9944 produces an animal model of Smith-Lemli-Opitz syndrome (SLOS), an autosomal recessive disease caused by defective cholesterol synthesis. This SLOS rat model undergoes progressive and irreversible degeneration of the neural retina, with associated pathological features of the retinal pigmented epithelium (RPE). Here, we provide further insights into the mechanism involved in the RPE pathology. In the SLOS rat model, markedly increased RPE apical autofluorescence is observed, compared to untreated animals, which correlates with increased levels of A2E and other bisretinoids. Utilizing cultured human induced pluripotent stem cell (iPSC)- derived SLOS RPE cells, we found significantly elevated steady-state levels of 7-dehydrocholesterol (7DHC) and decreased cholesterol levels (key biochemical hallmarks of SLOS). Western blot analysis revealed altered levels of the macroautophagy/autophagy markers MAP1LC3B-II and SQSTM1/p62, and build-up of ubiquitinated proteins. Accumulation of immature autophagosomes was accompanied by inefficient degradation of phagocytized, exogenously supplied retinal rod outer segments (as evidenced by persistence of the C-terminal 1D4 epitope of RHO [rhodopsin]) in SLOS RPE compared to iPSC-derived normal human control. SLOS RPE cells exhibited lysosomal pH levels and CTSD activity within normal physiological limits, thus discounting the involvement of perturbed lysosomal function. Furthermore, 1D4-positive phagosomes that accumulated in the RPE in both pharmacological and genetic rodent models of SLOS failed to fuse with lysosomes. Taken together, these observations suggest that defective phagosome maturation underlies the observed RPE pathology. The potential relevance of these findings to SLOS and the requirement of cholesterol for phagosome maturation are discussed. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group

Actuaciones profesionales realizadas en la farmacia comunitaria

Objetivo: Describir todas las actuaciones profesionales (AP) que se llevan a cabo como respuesta a las demandas realizadas por los usuarios en la farmacia comunitaria (FC). Material y métodos: Estudio observacional, descriptivo y transversal, realizado durante 6 meses en dos farmacias comunitarias de Denia (Alicante). La población de estudio fueron todas las demandas de servicio que realizaron los usuarios de ambas farmacias. La variable de estudio fue la AP, es decir, cada uno de los servicios demandados por el usuario en la FC: dispensación, indicación, automedicación, consultas y ventas, clasificándose cada uno en sus resoluciones e incidencias. Resultados: En el estudio se realizaron 30.617 AP, correspondiendo un 42% a la dispensación con receta, y se registró casi un 23% de incidencias. Las indicaciones farmacéuticas supusieron un 9% del total, resolviéndose en la mayoría de casos con la recomendación de un medicamento. Un 33% fueron demandas de automedicación, cursando con casi un 20% de incidencias. Un 7% fueron consultas y un 10% ventas de productos sanitarios. Conclusiones: Del total de AP realizadas, el 90% se consideran farmacéuticas. El 83% fueron dispensaciones de medicamentos, más de la mitad de éstas sin prescripción médica, lo que revela la importancia del asesoramiento farmacéutico en las dispensaciones sin receta. El hecho de que 9 de cada 10 incidencias que se producen en la dispensación con receta y en la automedicación sean por la falta de información del paciente nos pone en alerta sobre la necesidad de implementar medidas que mejoren esta carencia
