Persistent spatial clusters of high body mass index in a Swiss urban population as revealed by the 5-year GeoCoLaus longitudinal study.

OBJECTIVE: Body mass index (BMI) may cluster in space among adults and be spatially dependent. Whether and how BMI clusters evolve over time in a population is currently unknown. We aimed to determine the spatial dependence of BMI and its 5-year evolution in a Swiss general adult urban population, taking into account the neighbourhood-level and individual-level characteristics. DESIGN: Cohort study. SETTING: Swiss general urban population. PARTICIPANTS: 6481 georeferenced individuals from the CoLaus cohort at baseline (age range 35-74 years, period=2003-2006) and 4460 at follow-up (period=2009-2012). OUTCOME MEASURES: Body weight and height were measured by trained healthcare professionals with participants standing without shoes in light indoor clothing. BMI was calculated as weight (kg) divided by height squared (m(2)). Participants were geocoded using their postal address (geographic coordinates of the place of residence). Getis-Ord Gi statistic was used to measure the spatial dependence of BMI values at baseline and its evolution at follow-up. RESULTS: BMI was not randomly distributed across the city. At baseline and at follow-up, significant clusters of high versus low BMIs were identified and remained stable during the two periods. These clusters were meaningfully attenuated after adjustment for neighbourhood-level income but not individual-level characteristics. Similar results were observed among participants who showed a significant weight gain. CONCLUSIONS: To the best of our knowledge, this is the first study to report longitudinal changes in BMI clusters in adults from a general population. Spatial clusters of high BMI persisted over a 5-year period and were mainly influenced by neighbourhood-level income

Indication of spatially random occurrence of <i>Chlamydia</i>-like organisms in <i>Bufo bufo</i> tadpoles from ponds located in the Geneva metropolitan area.

Occurrence of bacteria belonging to the order &lt;i&gt;Chlamydiales&lt;/i&gt; was investigated for the first time in common toad ( &lt;i&gt;Bufo bufo&lt;/i&gt; ) tadpole populations collected from 41 ponds in the Geneva metropolitan area, Switzerland. A &lt;i&gt;Chlamydiales&lt;/i&gt; -specific real-time PCR was used to detect and amplify the &lt;i&gt;Chlamydiales&lt;/i&gt; 16S ribosomal RNA-encoding gene from the tails of 375 tadpoles. We found the studied amphibian populations to host &lt;i&gt;Chlamydia&lt;/i&gt; -like organisms (CLOs) attributable to the genera &lt;i&gt;Similichlamydia, Neochlamydia, Protochlamydia&lt;/i&gt; and &lt;i&gt;Parachlamydia&lt;/i&gt; (all belonging to the family &lt;i&gt;Parachlamydiaceae&lt;/i&gt; ), &lt;i&gt;Simkania&lt;/i&gt; (family &lt;i&gt;Simkaniaceae&lt;/i&gt; ) and &lt;i&gt;Estrella&lt;/i&gt; (family &lt;i&gt;Criblamydiaceae&lt;/i&gt; ); additionally, DNA from the genus &lt;i&gt;Thermoanaerobacter&lt;/i&gt; (family &lt;i&gt;Thermoanaerobacteriaceae&lt;/i&gt; ) was detected. Global autocorrelation analysis did not reveal a spatial structure in the observed CLOs occurrence rates, and association tests involving land cover characteristics did not evidence any clear effect on CLOs occurrence rates in &lt;i&gt;B. bufo.&lt;/i&gt; Although preliminary, these results suggest a random and ubiquitous distribution of CLOs in the environment, which would support the biogeographical expectation 'everything is everywhere' for the concerned microorganisms

L'anthropologie clinique au carrefour des psychothérapies

Dans le contexte de morcellement du champ psychothérapeutique, la tendance à la spécialisation technique, ainsi qu'à la disqualification mutuelle des différents courants, fait parfois oublier l'objet même de la psychothérapie, à savoir, l'être humain en souffrance. Plus que jamais, il apparaît donc nécessaire, pour le devenir d'une psychothérapie à visage humain, que tout thérapeute prenne conscience de la portée et de la limite de l'approche à laquelle il prête obédience, relativement aux autres courants : il est ainsi invité au double travail de clarification épistémologique sur les présupposés implicites à sa théorie et méthode, et de distanciation affective à l'égard du courant théorique auquel il est rattaché. L'anthropologie clinique d'inspiration phénoménologique apporte les outils indispensables à un tel travail

Previous thyroid disease and risk of thyroid cancer in Switzerland

A hospital-based case-control study of 86 cases of thyroid cancer and 317 controls was done in the Swiss Canton of Vaud. Patients with thyroid cancer tended to be better educated (odds ratio [OR] 2.1 for greater than or equal to 14 vs. less than or equal to 8 years of education 95% CI 1.1-4.1) and of higher social class than controls. Cases more often had a history of benign thyroid nodules (OR 25.2, 95% CI 7.6-83.6) and non-toxic goitre (OR 5.3, 95% CI 2.5-11.2). Furthermore, patients with thyroid cancer were more likely to have resided in endemic goitre areas (OR 1.7, 95% CI 1.0-3.0) and to have had first-degree relatives affected by benign thyroid disease (OR 3.9, 95% CI 2.1-7.1). Therefore, this study offers quantitative evidence of the association between various thyroid diseases and the risk of thyroid cancer which, despite difficulties in the classification of benign and malignant thyroid diseases, is remarkably consistent in studies from different countries

Programme de collaboration franco-suisse pour la création de nouvelles variétés de vigne durablement résistantes au mildiou et à l'oïdium

Une alternative aux traitements phytosanitaires pour lutter contre le mildiou et l'oïdium de la vigne est le développement de variétés résistantes. Leur création doit intégrer non seulement le niveau de résistance mais également sa durabilité, ainsi que les performances agronomiques notamment la productivité et la composition des baies qui doit convenir à la production de vins de haute qualité. L'Inra (France) a engagé le programme de sélection ResDur, basé sur le pyramidage des facteurs de résistance, en 2000. Il a conduit à l'inscription au catalogue français d'une première série de variétés à résistance polygénique – Artaban, Floreal, Vidoc, Voltis – en 2018. Agroscope (Suisse) a démarré la création de variétés résistantes en 1996, en mobilisant les résistances portées par des variétés allemandes, principalement Bronner. Un premier aboutissement a été l'homologation en Suisse de Divico et Divona, respectivement en 2013 et 2018. En 2009 l'Inra et Agroscope ont démarré un programme de sélection commun, visant à combiner les facteurs de résistance aux maladies présents de manière complémentaire dans leurs lignées respectives. Les croisements réalisés ont généré, après sélection assistée par marqueurs, 400 descendants porteurs des facteurs de résistanceRpv1, Rpv10 et/ou Rpv3 ; Run1, Ren3 et/ou Ren3.2. Leur phénotypage agronomique et œnologique est réalisé dans le cadre d'un réseau d'essais situés dans les deux Instituts à Colmar (FR) et à Pully (CH). Les premières observations pluriannuelles, portant sur 80 descendants, ont permis d'étudier leur stabilité phénotypique pour les caractères de résistance, les traits culturaux et la qualité des vins. A l'issue de cette étape, quinze variétés candidates ont été sélectionnées et installées en essais d'évaluation de leur valeur agronomique, technologique et environnementale (VATE) en Valais (CH), ainsi que dans trois régions françaises (Champagne, Val de Loire, Vallée du Rhône). L'inscription au catalogue des premières co-obtentions Inra/Agroscope est prévue à l'horizon 2024–2025

Molecular characterization of cell types in the squid Loligo vulgaris.

Cephalopods are set apart from other mollusks by their advanced behavioral abilities and by the complexity of their nervous systems. Because of the great evolutionary distance that separates vertebrates from cephalopods, it is evident that higher cognitive features have evolved separately in these clades despite the similarities that they share. Alongside their complex behavioral abilities, cephalopods have evolved specialized cells and tissues, such as the chromatophores for camouflage or suckers to grasp prey. Despite significant progress in genome and transcriptome sequencing, the molecular identities of cell types in cephalopods remain largely unknown. We here combine single-cell transcriptomics with in situ gene expression analysis to uncover cell type diversity in the European squid Loligo vulgaris. We describe cell types that are conserved with other phyla such as neurons, muscles, or connective tissues but also cephalopod-specific cells, such as chromatophores or sucker cells. Moreover, we investigate major components of the squid nervous system including progenitor and developing cells, differentiated cells of the brain and optic lobes as well as sensory systems of the head. Our study provides a molecular assessment for conserved and novel cell types in cephalopods and a framework for mapping the nervous system of L. vulgaris
