Zoonotic occupational diseases in forestry workers: Lyme borreliosis, tularemia and leptospirosis in Europe

INTRODUCTION: Forestry workers and other people who come into close contact with wild animals, such as hunters, natural science researchers, game managers or mushroom/berry pickers, are at risk of contracting bacterial, parasitological or viral zoonotic diseases. Synthetic data on the incidence and prevalence of zoonotic diseases in both animals and humans in European forests do not exist. It is therefore difficult to promote appropriate preventive measures among workers or people who come into direct or indirect contact with forest animals. OBJECTIVES: The objectives of this review are to synthesise existing knowledge on the prevalence of the three predominant bacterial zoonotic diseases in Europe, i.e. Lyme borreliosis, tularemia and leptospirosis, in order to draw up recommendations for occupational or public health. METHODS: 88 papers published between 1995-2013 (33 on Lyme borreliosis, 30 on tularemia and 25 on leptospirosis) were analyzed. CONCLUSIONS: The prevalences of these three zoonotic diseases are not negligible and information targeting the public is needed. Moreover, the results highlight the lack of standardised surveys among different European countries. It was also noted that epidemiological data on leptospirosis are very scarce.

Historia de las mujeres y memoria histórica: Manuela Sáenz interpela a Simón Bolívar (1822-1830)

En la construcción de la historia de las mujeres, es necesario revisar a fondo las manipulaciones de la memoria sobre la presencia femenina, ya sea oculta o visible, en todas las sociedades históricas y actuales. Las interpretaciones muy divergentes de un icono feme- nino, Manuela Sáenz – la más famosa amante de Simón Bolívar – son un ejemplo paradig- mático que nos permite reflexionar, desde lo particular, sobre temas de ámbito más general.

Ultrastructural study of spermiogenesis and the spermatozoon of the proteocephalidean cestode Barsonella lafoni de Chambrier et al., 2009, a parasite of the catfish Clarias gariepinus (Burchell, 1822) (Siluriformes, Clariidae)

Spermiogenesis in the proteocephalidean cestode Barsonella lafoni de Chambrier et al., 2009 shows typical characteristics of the type I spermiogenesis. These include the formation of distal cytoplasmic protrusions forming the differentiation zones, lined by cortical microtubules and containing two centrioles. An electron-dense material is present in the apical region of the differentiation zone during the early stages of spermiogenesis. Each centriole is associated to a striated rootlet, being separated by an intercentriolar body. Two free and unequal flagella originate from the centrioles and develop on the lateral sides of the differentiation zone. A median cytoplasmic process is formed between the flagella. Later these flagella rotate, become parallel to the median cytoplasmic process and finally fuse proximodistally with the latter. It is interesting to note that both flagellar growth and rotation are asynchronous. Later, the nucleus enlarges and penetrates into the spermatid body. Finally, the ring of arching membranes is strangled and the young spermatozoon is detached from the residual cytoplasm. The mature spermatozoon presents two axonemes of the 9 +"1" trepaxonematan pattern, crested body, parallel nucleus and cortical microtubules, and glycogen granules. Thus, it corresponds to the type II spermatozoon, described in almost all Proteocephalidea. The anterior extremity of the gamete is characterized by the presence of an apical cone surrounded by the lateral projections of the crested body. An arc formed by some thick and parallel cortical microtubules appears at the level of the centriole. They surround the centriole and later the first axoneme. This arc of electron-dense microtubules disorganizes when the second axoneme appears, and then two parallel rows of thin cortical microtubules are observed. The posterior extremity of the male gamete exhibits some cortical microtubules. This type of posterior extremity has never been described in proteocephalidean cestodes. The ultrastructural features of the spermatozoon/spermiogenesis of the Proteocephalidea species are analyzed and compared.

Richard Rorty i una aproximació pragmatista al liberalisme polític de John Rawls

Aquest article es proposa explorar la possibilitat d'apropar a la concepció del liberalisme polític metafilosòfic de John Rawls des del punt de vista pragmatista de Richard Rorty. La proposta està motivada per les similituds que es poden observar entre elles respecte de la finalitat i la sortida d'una concepció política. El resultat final de l'article és ambigua: d'una banda, no sembla tan descabellat afirmar que la teoria de Rawls es pot llegir sense més dificultats des d'una perspectiva pragmàtica, d'altra banda, hi ha alguns aspectes importants en els quals un liberalisme polític de Rawls segueix sent incompatible amb una concepció política de Rorty

La población infantil de Barcelona (1898-1961): una evaluación de su estado nutricional a partir de estadísticas antropométricas

En los ejercicios de evaluación de la denominada “penalización urbana”, la mortalidad infantil y juvenil suele ser uno o de los indicadores más habituales. Disponer de indicadores relativos a sus condiciones de salud es más difícil. Una opción son los datos antropométricos. Este tipo de información abunda para las poblaciones adultas –especialmente las masculinas enroladas en los ejércitos- pero es más escasa para las infantiles. El propósito de este trabajo es contribuir al conocimiento de las condiciones de salud de este grupo de la población barcelonesa durante algo más de la primera mitad del siglo XX, a partir del estudio de un conjunto de 9 estadísticas antropométricas publicadas entre 1900 y 1961. A través de una reconstrucción estadística, mediante el empleo de las Tablas de Crecimiento de la población infantil española elaboradas por M. Hernández, E Sánchez y B.Sobradillo en 1995, se han estandarizado las tallas y comparado los Indices de Masa Corporal calculados a partir de las medidas publicadas. Los principales resultados son: a) La presencia de diferentes pautas en las trayectorias seculares de crecimiento de niños y niñas. El crecimiento de las tallas entre los niños fue de 1,09 cm por decenio entre 1898 y 1945 y de 1,40 entre 1945 y 1961. Mientras que en el caso de las niñas entre 1898 y 1945 fue de 0,14 cm por decenio para aumentar a 2,18 entre 1945 y 1981. b) Las diferencias sociales en los indicadores antropométricos persisten a lo largo del periodo estudiado c) Los porcentajes de población infantil con probable malnutrición se situaron en torno al 24 por ciento para las generaciones nacidas entre 1885 y 1940, para ir descendiendo de forma irreversible en las nacidas a partir de 1950. De este modo en la década años setenta del siglo XX no parece existir evidencia de tal estado en la población infantil barcelonesa.
