La mobilitat urbana és una de les temàtiques més importants a les ciutats ja que convergeixen diversos aspectes a nivell social i ambiental. El present article es centra en el sistema de mobilitat de la ciutat de Sitges tot avaluant l’estat de la xarxa viària, el parc de vehicles, els sistemes de transport i els serveis bàsics actuals. En l’anàlisi socioambiental de les variables d’aquest àmbit, s’han detectat una sèrie de problemes com ara una distribució no equitativa dels serveis bàsics, desigualtat en la distribució de carrers vianalitzats i carrils bici i manca d’homogeneïtat en la distribució de pàrquings. Els resultats obtinguts permeten proposar una sèrie de millores en busca d’una mobilitat més sostenible. Millorar les parades de bus que no tenen sistema de marquesina per a protegir-les del fred i el sol, augmentar potencialment el carril bici desplegant-lo per carrers que no en tenen, desenvolupar campanyes per a fomentar l’ús de la bici i augmentar la presència de carrers d’exclusiu ús per a vianants.

Background and objective. - Access to care in French disadvantaged urban areas remains an issue despite the implementation of local healthcare structures. To understand this contradiction, we investigated social representations held by inhabitants of such areas, as well as those of social and healthcare professionals, regarding events or behaviours that can impact low-income individuals' health. Method. - In the context of a health diagnosis, 288 inhabitants living in five disadvantaged districts of Aix-les-Bains, as well as 28 professionals working in these districts, completed an open-ended questionnaire. The two groups of respondents were asked to describe what could have an impact on health status from the inhabitants' point of view. The textual responses were analyzed using the Alceste method. Results. - We observed a number of differences in the way the inhabitants and professionals represented determinants of health in disadvantaged urban areas: the former proposed a representation mixing personal responsibility with physiological, social, familial, and professional aspects, whereas the latter associated health issues with marginalization (financial, drug, or alcohol problems) and personal responsibility. Both inhabitants and professionals mentioned control over events and lifestyle as determinants of health. Discussion. - The results are discussed regarding the consequences of these different representations on the beneficiary - healthcare-provider relationship in terms of communication and trust.

Autosomal recessive cutis laxa type I (ARCL type I) is characterized by generalized cutis laxa with pulmonary emphysema and/or vascular complications. Rarely, mutations can be identified in FBLN4 or FBLN5. Recently, LTBP4 mutations have been implicated in a similar phenotype. Studying FBLN4, FBLN5, and LTBP4 in 12 families with ARCL type I, we found bi-allelic FBLN5 mutations in two probands, whereas nine probands harbored biallelic mutations in LTBP4. FBLN5 and LTBP4 mutations cause a very similar phenotype associated with severe pulmonary emphysema, in the absence of vascular tortuosity or aneurysms. Gastrointestinal and genitourinary tract involvement seems to be more severe in patients with LTBP4 mutations. Functional studies showed that most premature termination mutations in LTBP4 result in severely reduced mRNA and protein levels. This correlated with increased transforming growth factor-beta (TGFβ) activity. However, one mutation, c.4127dupC, escaped nonsense-mediated decay. The corresponding mutant protein (p.Arg1377Alafs(*) 27) showed reduced colocalization with fibronectin, leading to an abnormal morphology of microfibrils in fibroblast cultures, while retaining normal TGFβ activity. We conclude that LTBP4 mutations cause disease through both loss of function and gain of function mechanisms.

This article analyses the spatial organization of Montebelluna's industrial district (Italy) as an exemple of the dinamics of urbanization phenomenon in small urban areas. The study is divided in two parts: in the first one I present the social organisation's model of production named «industrial district» and its relation with the space, which is characterizeded by the rising of diffused urbanization settlements; in the second part I try to verify some explanatory factors pointed out by different autors in this specific area with an historical analysis of processes point of view. The diffused organisation of economic and housing activity show a change in the urban morphology

En el procés de ser jove hi ha implícites dinàmiques de socialització i de relació. Tot i ser un procés habitual, no deixa de sorprendre la incorporació, a través de l’acció dels joves, de nous valors i nous referents en els constructes culturals ja establerts, que, en termes molt generals, identifiquen fins aquest moment els que en podríem dir la massa adulta. L’article es basa en un treball empíric fet a la ciutat de Tarragona, combinant les opinions directes de 21 joves creadors, l’observació dels carrers (especialment dels graffitis i instal•lacions plàstiques que hi podem trobar) i l’anàlisi de fonts bibliogràfiques i documentals amb les que es planteja els referents teòrics i contextuals

The aim of this study was to determine the occurrences of the group A rotavirus (RVA), norovirus (NoV) and human adenovirus (HAdV) in the surface waters of an urban lagoon (Rodrigo de Freitas Lagoon) in the city of Rio de Janeiro, Brazil. During one year of surveillance, water samples were obtained from the lagoon and other interconnected ecosystems (river and beach). The samples were concentrated using an adsorption-elution method with a negatively charged membrane and tested by qualitative and quantitative polymerase chain reaction assays. RVA was the most prevalent virus detected (24.3%) with a viral load ranging from 3.0 x 10¹-5.6 x 10(4) genome copies/L, followed by NoV (18.8%) and HAdV (16.7%). Considering water samples suitable for bathing, according to Escherichia coli criterion (< 2,000 most probable number/100 mL), viruses were detected in 50% (57/114) of them. Physicochemical parameters were also measured and showed possible correlations between turbidity and RVA presence and between pH and NoV presence. These data demonstrate the importance of considering viral parameters to ensure water quality and the utilisation of these parameters as additional tools for the characterisation of environmental contamination.

El temps del mal. L’experiència i la gestió de la cronicitat en adults. El principal objectiu d’aquesta recerca és l’estudi de l’experiència i la gestió diària de la cronicitat, entenent-la com a categoria analítica que engloba els processos de malalties i/o malestars crònics, biomèdicament diagnosticats o no, que perduren en el temps. La recerca es centra en adults entre 30 i 50 anys amb problemes crònics de salut que impliquin algun tipus de discapacitat i/o dependència (a nivell moderat), i s’ubica en l’àmbit urbà i en la comunitat autònoma de Catalunya (dins del context de l’estat Espanyol). L’estudi analitzarà la gestió individual i social de la cronicitat a través dels itineraris terapèutics i pràctiques assistencials dels processos de salut/malaltia/atenció prenent l’autoatenció com a principal categoria analítica. Per altra banda, es descriurà el rol dels serveis assistencials de la sanitat pública i dels serveis socials, per veure com es duu a terme la gestió – polítiques públiques - de la cronicitat en un país amb estat del benestar com Espanya. L’experiència de la cronicitat s’explorarà a través de les narratives de la vivència de la malaltia/malestar tan com a representació cultural – que dóna compte de les relacions, interaccions i respostes socials – i des d’una perspectiva fenomenològica que ens permet comprendre la naturalesa del patiment en l’experiència viscuda del cos malalt. Aquesta recerca espera poder fer aportacions pertinents que contribueixin des de l’antropologia però amb la intenció d’obrir un diàleg públic i interdisciplinar – professionals de la salut, experts en polítiques públiques i públic en general - a la resolució de l’actual problema de salut pública d’increment de cronicitat. El model públic d’atenció a la salut espanyol es va dissenyar per resoldre problemes de salut aguts, malgrat la major part dels usuaris actuals presentes problemes de salut crònics. L’actual crisi econòmica que amenaça aquest pilar de l’estat del benestar és, alhora, una oportunitat per replantejar-ho.

Patterns of malaria cases were compared between the department of Meta and the municipality of Puerto Gaitán, Colombia, to examine temporal change in malaria from 2005-2010. During this time frame in Meta the mean ratio was 2.53; in contrast, in Puerto Gaitán it was 1.41, meaning that a surprisingly high proportion of Plasmodium falciparum cases were reported from this municipality. A detailed analysis of data from Puerto Gaitán for 2009 and 2010 detected a significant difference (χ2, p < 0.001) in the distribution of plasmodia, with Plasmodium vivax more prevalent in 2009 and P. falciparum in 2010. Males had the highest number of cases but there was no difference in the distribution of cases between sexes and years. In both years, for both sexes, people 16-40 accounted for the majority of cases (58.9% in 2009; 60.4% in 2010). There were significant differences in the distribution of both P. vivax (χ2, p < 0.01) and P. falciparum cases (χ2, p < 0.05) by geographic setting (urban vs. non-urban) between years. Urban cases of both P. vivax and P. falciparum are recorded in this study for the first time in Puerto Gaitán, possibly the result of area wide displacement and migration due to armed conflict.

Amb les transformacions de la societat postfordista i la progressiva retirada dels estats de Benestar, emergeixen per una part, noves modalitats de transicions juvenils de bloqueig i precarietat, així com noves formes de marginalitat urbana per efecte de tres components; l’extensió de l’atur de llarga durada i la relació precaritzada amb el treball, la relegació en barris de concentració de la pobresa i l’estigmatització territorial; dinàmiques que generen la nova marginalitat avançada. Aquest treball, planteja una aproximació teòrica als condicionants i els efectes de les noves formes de marginalitat sobre els joves en determinats contextos territorials, plantejant hipòtesis respecte el micro-context de Salt

Traditional mosquito control strategies rely heavily on the use of chemical insecticides. However, concerns about the efficiency of traditional control methods, environmental impact and emerging pesticide resistance have highlighted the necessity for developing innovative tools for mosquito control. Some novel strategies, including release of insects carrying a dominant lethal gene (RIDL®), rely on the sustained release of modified male mosquitoes and therefore benefit from a thorough understanding of the biology of the male of the species. In this report we present the results of a mark-release-recapture study aimed at: (i) establishing the survival in the field of laboratory-reared, wild-type male Aedes aegypti and (b) estimating the size of the local adult Ae. aegypti population. The study took place in Panama, a country where recent increases in the incidence and severity of dengue cases have prompted health authorities to evaluate alternative strategies for vector control. Results suggest a life expectancy of 2.3 days for released male mosquitoes (confidence interval: 1.78-2.86). Overall, the male mosquito population was estimated at 58 males/ha (range 12-81 males/ha), which can be extrapolated to an average of 0.64 pupae/person for the study area. The practical implications of these results are discussed.

Helicobacter pylori infection is one of the most common infections worldwide and is associated with gastric diseases. Virulence factors such as VacA and CagA have been shown to increase the risk of these diseases. Studies have suggested a causal role of CagA EPIYA-C in gastric carcinogenesis and this factor has been shown to be geographically diverse. We investigated the number of CagA EPIYA motifs and the vacA i genotypes in H. pylori strains from asymptomatic children. We included samples from 40 infected children (18 females and 22 males), extracted DNA directly from the gastric mucus/juice (obtained using the string procedure) and analysed the DNA using polymerase chain reaction and DNA sequencing. The vacA i1 genotype was present in 30 (75%) samples, the i2 allele was present in nine (22.5%) samples and both alleles were present in one (2.5%) sample. The cagA-positive samples showed distinct patterns in the 3’ variable region of cagA and 18 of the 30 (60%) strains contained 1 EPIYA-C motif, whereas 12 (40%) strains contained two EPIYA-C motifs. We confirmed that the studied population was colonised early by the most virulent H. pylori strains, as demonstrated by the high frequency of the vacA i1 allele and the high number of EPIYA-C motifs. Therefore, asymptomatic children from an urban community in Fortaleza in northeastern Brazil are frequently colonised with the most virulent H. pylori strains.
