Managérialisation et Etat social : satisfaction et motivation d'intervenants et d'intervenantes socio-éducatives dans des contextes plus ou moins managérialisés

La contribution d'Yves Emery et Julien Niklaus étudie les effets du new managerialism dans le secteur social. Les nouveaux outils de pilotage ont profondément transformé les conditions cadres du travail social, de l'organisation des tâches ainsi que de l'action professionnelle. Les auteurs cherchent à savoir dans quelle mesure ces transformations influencent la motivation et la satisfaction au travail des travailleurs et travailleuses sociales. Ils comparent deux institutions présentant des degrés différents de managérialisation et constatent, avec surprise, une motivation supérieure dans les organisations davantage managérialisées, alors que la satisfaction au travail ne présente pas de différences.

The cost of breathing in stable chronic obstructive pulmonary disease.

1. The hypermetabolism frequently observed at rest in patients with chronic obstructive pulmonary disease has been attributed to a high cost of breathing. However, measurement of the cost of breathing by the usual hyperventilation procedure is fraught with methodological problems. The purpose of this study was to measure more directly the cost of breathing in a group of ambulatory patients with stable chronic obstructive pulmonary disease. 2. The cost of breathing was calculated as the difference in oxygen consumption measured by indirect calorimetry between spontaneous breathing and noninvasive mechanical ventilation. Inspiratory muscle rest was achieved by negative or positive pressure ventilation and assessed by the recording of surface electromyograms of the diaphragm and parasternal intercostal muscles. 3. Seven tests were performed in six ambulatory patients with stable chronic obstructive pulmonary disease, four tests using positive pressure ventilation and three with negative pressure ventilation. During mechanical ventilation, the electromyographic activity of the diaphragm decreased by 70 +/- 22%, while that of the parasternals was suppressed in four tests, and remained unchanged in three. However, oxygen consumption was only 1.6 +/- 6.2% lower during mechanical ventilation. 4. The cost of breathing measured in this study was therefore much lower than previously published values. Stress was not likely to influence the results, as both the heart rate and plasma catecholamines did not change between spontaneous breathing and mechanical ventilation. These results suggest that the cost of breathing in ambulatory patients with stable chronic obstructive pulmonary disease may be lower than previously estimated.

Mutations in CTC1, encoding conserved telomere maintenance component 1, cause Coats plus.

Coats plus is a highly pleiotropic disorder particularly affecting the eye, brain, bone and gastrointestinal tract. Here, we show that Coats plus results from mutations in CTC1, encoding conserved telomere maintenance component 1, a member of the mammalian homolog of the yeast heterotrimeric CST telomeric capping complex. Consistent with the observation of shortened telomeres in an Arabidopsis CTC1 mutant and the phenotypic overlap of Coats plus with the telomeric maintenance disorders comprising dyskeratosis congenita, we observed shortened telomeres in three individuals with Coats plus and an increase in spontaneous γH2AX-positive cells in cell lines derived from two affected individuals. CTC1 is also a subunit of the α-accessory factor (AAF) complex, stimulating the activity of DNA polymerase-α primase, the only enzyme known to initiate DNA replication in eukaryotic cells. Thus, CTC1 may have a function in DNA metabolism that is necessary for but not specific to telomeric integrity.

Polypharmacy as predictor of drug cost, length of hospital stay and mortality rate in nursing homes : a retrospective analysis of pharmacy medication records

Background and objectives: Polypharmacy (PP) is a typical con-sequence of multiple chronic conditions in elderly patients. PP is commonly defined as the use of multiple concurrent drug therapies although a standard definition is not used. The aims of this study were to assess the PP rate among nursing home (NH) residents using the data of the pharmacy medication records and to investigate the threshold level of PP as predictor of drug cost, length of hospital stay and mortality rate

Cost effectiveness and cost utility of risedronate for osteoporosis treatment and fracture prevention in women: a Swiss perspective.

OBJECTIVES: To assess the incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR) of risedronate compared to no intervention in postmenopausal osteoporotic women in a Swiss perspective. METHODS: A previously validated Markov model was populated with epidemiological and cost data specific to Switzerland and published utility values, and run on a population of 1,000 women of 70 years with established osteoporosis and previous vertebral fracture, treated over 5 years with risedronate 35 mg weekly or no intervention (base case), and five cohorts (according to age at therapy start) with eight risk factor distributions and three lengths of residual effects. RESULTS: In the base case population, the ICER of averting a hip fracture and the ICUR per quality-adjusted life year gained were both dominant. In the presence of a previous vertebral fracture, the ICUR was below euro45,000 (pound30,000) in all the scenarios. For all osteoporotic women>or=70 years of age with at least one risk factor, the ICUR was below euro45,000 or the intervention may even be cost saving. Age at the start of therapy and the fracture risk profile had a significant impact on results. CONCLUSION: Assuming a 2-year residual effect, that ICUR of risedronate in women with postmenopausal osteoporosis is below accepted thresholds from the age of 65 and even cost saving above the age of 70 with at least one risk factor.

Etudes Coût-efficacité: ce que devraient retenir les médecins [Cost-effectiveness analyses: what doctors should know]

The resources of our heath care system are limited. Choices in the attribution of resources are necessary to ensure its stability. A cost-effectiveness analysis compares the effects of one health intervention to another, taking into account the costs (including the saved costs) and the saved life years, adjusted for the quality of life (cost-utility). Cost-effectiveness analyses should take the societal perspective and the studied intervention should be compared to a relevant intervention actually in use. Physicians, at the interface between patients and payers, are in an ideal position to interpret, or even perform cost-effectiveness analysis, and to promote the interventions that are most effective and that have a reasonable cost.

In vivo survival of teicoplanin-resistant Staphylococcus aureus and fitness cost of teicoplanin resistance.

Glycopeptide resistance, in a set of in vitro step-selected teicoplanin-resistant mutants derived from susceptible Staphylococcus aureus SA113, was associated with slower growth, thickening of the bacterial cell wall, increased N-acetylglucosamine incorporation, and decreased hemolysis. Differential transcriptome analysis showed that as resistance increased, some virulence-associated genes became downregulated. In a mouse tissue cage infection model, an inoculum of 10(4) CFU of strain SA113 rapidly produced a high-bacterial-load infection, which triggered MIP-2 release, leukocyte infiltration, and reduced leukocyte viability. In contrast, with the same inoculum of the isogenic glycopeptide-resistant derivative NM67, CFU initially decreased, resulting in the elimination of the mutant in three out of seven cages. In the four cages in which NM67 survived, it partially regained wild-type characteristics, including thinning of the cell wall, reduced N-acetylglucosamine uptake, and increased hemolysis; however, the survivors also became teicoplanin hypersusceptible. The elimination of the teicoplanin-resistant mutants and selection of teicoplanin-hypersusceptible survivors in the tissue cages indicated that glycopeptide resistance imposes a fitness burden on S. aureus and is selected against in vivo, with restoration of fitness incurring the price of resistance loss.
