Quand les greniers se remplissent: Les bénéfices du partenariat entre la recherche agronomique, la vulgarisation agricole et des organisations paysannes au Mali

This publication is a collation and summary of the major achievements of the Agricultural Research Station of Cinzana (SRAC) and the Capacity Building for Sustainable Agriculture Project (PRECAD). Both projects, created in 1983 and 2006, respectively, have been developed through close collaboration between the Rural Economy Institute (IER) responsible for agricultural research in Mali and the Syngenta Foundation for Sustainable Agriculture (SFSA), formerly the Ciba-Geigy Foundation. The publication covers the period from 1979 to 2009 and includes, where available, some key information for the year 2010. It is aimed at a wide audience and provides an overview of the work carried out in Mali by an agricultural research station and an extension project. It highlights the obstacles and opportunities encountered by the SRAC and PRECAD, as well as the successes and difficulties arising from their work.

Coopération cardio-vasculaire avec l’Hôpital BPKIHS, à Dharan Bazar, Népal

Grâce à une collaboration entre des cardiologues suisses, la Fondation Cœur de la Tour et l’Hôpital universitaire BPKIHS à Dharan, il a été possible en l’espace de deux ans, en utilisant une approche «hybride», de développer le premier programme de cardiologie invasive et interventionnelle indépendant dans l’est du Népal. Depuis janvier 2011, 496 patients ont pu être investigués et traités en 23 mois (coronarographies, angioplasties coronaires, pose de pacemakers temporaires et définitifs, drainages péricardiques, etc.). Parallèlement à cet axe principal, la Fondation a également soutenu un programme préexistant de prévention des facteurs de risque cardio-vasculaires dans cette région, et a apporté un appui financier à la mise sur pied d’un projet de dépistage et de traitement des atteintes cardiaques rhumatismales chez les enfants en âge scolaire.

The nasal microbiota in infants with cystic fibrosis in the first year of life: a prospective cohort study.

BACKGROUND Respiratory tract infections and subsequent airway inflammation occur early in the life of infants with cystic fibrosis. However, detailed information about the microbial composition of the respiratory tract in infants with this disorder is scarce. We aimed to undertake longitudinal in-depth characterisation of the upper respiratory tract microbiota in infants with cystic fibrosis during the first year of life. METHODS We did this prospective cohort study at seven cystic fibrosis centres in Switzerland. Between Feb 1, 2011, and May 31, 2014, we enrolled 30 infants with a diagnosis of cystic fibrosis. Microbiota characterisation was done with 16S rRNA gene pyrosequencing and oligotyping of nasal swabs collected every 2 weeks from the infants with cystic fibrosis. We compared these data with data for an age-matched cohort of 47 healthy infants. We additionally investigated the effect of antibiotic treatment on the microbiota of infants with cystic fibrosis. Statistical methods included regression analyses with a multivariable multilevel linear model with random effects to correct for clustering on the individual level. FINDINGS We analysed 461 nasal swabs taken from the infants with cystic fibrosis; the cohort of healthy infants comprised 872 samples. The microbiota of infants with cystic fibrosis differed compositionally from that of healthy infants (p=0·001). This difference was also found in exclusively antibiotic-naive samples (p=0·001). The disordering was mainly, but not solely, due to an overall increase in the mean relative abundance of Staphylococcaceae in infants with cystic fibrosis compared with healthy infants (multivariable linear regression model stratified by age and adjusted for season; second month: coefficient 16·2 [95% CI 0·6-31·9]; p=0·04; third month: 17·9 [3·3-32·5]; p=0·02; fourth month: 21·1 [7·8-34·3]; p=0·002). Oligotyping analysis enabled differentiation between Staphylococcus aureus and coagulase-negative Staphylococci. Whereas the analysis showed a decrease in S aureus at and after antibiotic treatment, coagulase-negative Staphylococci increased. INTERPRETATION Our study describes compositional differences in the microbiota of infants with cystic fibrosis compared with healthy controls, and disordering of the microbiota on antibiotic administration. Besides S aureus, coagulase-negative Staphylococci also contributed to the disordering identified in these infants. These findings are clinically important in view of the crucial role that bacterial pathogens have in the disease progression of cystic fibrosis in early life. Our findings could be used to inform future studies of the effect of antibiotic treatment on the microbiota in infants with cystic fibrosis, and could assist in the prevention of early disease progression in infants with this disorder.
