Identification of the potential habitat of European anchovy (Engraulis encrasicolus) at different life stages in relation to environmental conditions is an interesting subject from both ecological and management points of view. For this purpose, acoustic data from different seasons and different parts of the Mediterranean Sea along with satellite environmental and bathymetry data were modelled using generalized additive models. Similarly, egg distribution data from summer ichthyoplankton surveys were used to model potential spawning habitat. Selected models were used to produce maps presenting the probability of anchovy presence (adults, juveniles and eggs) in the entire Mediterranean basin, as a measure of habitat adequacy. Bottom depth and sea surface chlorophyll concentration were the variables found important in all models. Potential anchovy habitats were located over the continental shelf for all life stages examined. An expansion of the potential habitat from the peak spawning (early summer) to the late spawning season (early autumn) was observed. However, the most suitable areas for the presence of anchovy spawners seem to maintain the same size between seasons. Potential juvenile habitats were associated with highly productive inshore waters, being less extended and closer to coast during winter than late autumn. Potential spawning habitat in June and July based on ichthyoplankton surveys overlapped but were wider in extent compared with adult potential habitat from acoustics in the same season. Similarities and dissimilarities between the anchovy habitats as well as comparisons with sardine habitats in the oligotrophic Mediterranean Sea and other ecosystems with higher productivity are discussed.

Background and objectives The Covid-19 pandemic has put healthcare professionals around the world in an unprecedented challenge. This may cause some emotional difficulties and mental health problems. The aim of the present study was to analyze the emotional status among the health care workers form the Hospital of Igualada (Barcelona), while they were facing with Covid-19 in one of the most affected regions in all of Europe. Patients and methods A total of 395 participants were included in the study. A cross-sectional assessment was carried out between the months of March and April. Information about anxiety, depression, and stress was gathered. We also collected demographic data and concerning potentially stressful factors. Results A significant proportion of professionals reported symptoms of anxiety (31.4%) and depression (12.2%) from moderate to severe intensity. Symptoms of acute stress were reported by 14.5% of participants. We performed a regression analysis, which explained the 30% of the variance associated with the degree of emotional distress (R² = 0.30). The final model reveals that females (or young males), who are working in the frontline as nursing assistants, caretakers or radiology technicians, with the uncertainty of a possible infection, the perception of inadequate protection measures and having experienced the death of a close person by Covid-19, showed a heightened risk of experiencing psychological distress. Conclusions Coping with the Covid-19 pandemic caused a significant impact on emotional status of healthcare workers involved in this study.

Antecedentes y objetivo La actual pandemia de Covid-19 ha puesto a los profesionales sanitarios de todo el mundo ante un desafío sin precedentes. Esto les ha podido causar dificultades emocionales y problemas de salud mental. El objetivo del presente estudio fue analizar el estado emocional de los trabajadores del Hospital de Igualada (Barcelona), mientras se enfrentaban a uno de los focos de contagio más importantes de Europa. Pacientes y métodos Se incluyó a un total de 395 trabajadores. Se realizó una evaluación transversal entre los meses de marzo y abril. Se recogió información sobre síntomas de ansiedad, depresión, estrés. También se recogieron datos demográficos y sobre factores potencialmente estresantes. Resultados Un porcentaje significativo de profesionales reportó síntomas de ansiedad (71,6%) y depresión (60,3%). El 14,5% informó de síntomas de estrés agudo. Se realizó un análisis de regresión que explicó el 30% de la variancia asociada al nivel de malestar emocional (Ry = 0,30). Los factores de riesgo asociados a mayor malestar psicológico fueron el hecho de ser mujer (o hombre joven), trabajar como auxiliar de enfermería, celador o técnico de radiología, estar en contacto directo con pacientes Covid-19, no haber realizado la PCR, tener la sensación de no contar con los elementos de protección personales y haber experimentado la muerte de una persona cercana por Covid-19. Conclusiones El afrontamiento inicial de la situación de crisis asociada a la pandemia de Covid-19 tuvo un importante impacto emocional en los profesionales sanitarios analizados.

The distributions of micronekton layers in the Balearic Sea (western Mediterranean) were investigated by acoustic methods. Two multidisciplinary surveys were carried out in late autumn 2009 and summer 2010, recording acoustic, biological, and hydrographic data. We described acoustic layers, migratory behavior, sampled species, and water masses processes. Acoustic modeling of gas-bearing organisms was employed to explain differences between acoustic estimates and sampled abundances. The influence of environmental variables on the vertical distribution and migration pattern of these organisms was analyzed. The thermocline depth was related to the preferred depth for migrating myctophids, while nonmigrant species dwelled in the oxygen minimum zone of the water column both in late autumn and summer periods.Résumé : La distribution des couches de micronecton a été étudiée par méthode acoustique dans la mer des Baléares (Méditer-ranée occidentale). Deux campagnes multidisciplinaires ont été menées en automne 2009 et en été 2010, par mesures acoustique et échantillonnages biologique et hydrologique. La description des couches acoustiques, le comportement migratoire, les espèces échantillonnées et les couches d'eau sont fournies. La modélisation acoustique des organismes de type gas bearing est utilisée pour expliquer le mascage qui conduit á des différences avec les abondances mesurées. Leur préférence pour certaines gammes de variables externes dans la distribution verticale et le model de migration de ces organismes est analysée. La profondeur de la thermocline a été associée á la profondeur de migration préférée des myctophidés, de même la zone de la colonne d'eau présentant le minimum d'oxygène dissous correspond á la zone de résidence des espèces non-migrantes, tous les deux en automne et en été.

The acetabular labrum augments femoral head coverage within the acetabulum and contributes to hip joint stability. This has led to an increasing interest in procedures dedicated to preservation of the labrum. An allogenic labral transplantation performed in a patient who had previously undergone a partial labral resection is presented.
