While private clinics are generally recognized as important care givers in current African cities, the sector remains under-studied in the social sciences. The research for my master thesis focused on the creation of a hospital anchored to a public-private partnership, including the World Bank, the Beninese Health Ministry and a private non-governmental association. The main purpose of my enquiry is to understand how the status of this hospital influences (or not) its organization and its use by clients. Therefore, I firstly analyze the emergence and the diversity of the Beninese private health sector as well as the connotations of the notion of public-private partnership. These two points help to understand the particular context of creation of the studied public-private partnership and how it was imposed to the Ministry by the World Bank. Secondly, my research shows how the creation is nowadays read in different ways by the various actors in order to claim their rights on the management of the hospital. Thirdly, focusing on collaboration between the different categories of workers and their relationships with clients, I describe formal and informal organization of this private hospital. This part underlines the particularities of private direction in comparison with well-known studies of public centers. Using these data, I also try to understand why clients come to this specific hospital. I argue that status is not as important in their choice. [less ▲]

A set of different green fluorescent protein (GFP) Escherichia coli reporter strains have been evaluated in mini- and stirred bioreactors operating in fed-batch mode with different degrees of perturbations in order to estimate their potential use as process-related stress biosensor. The mini-bioreactor platform comprises a set of parallel shake flasks operating in fed-batch mode. The advantage of this system is its high experimental throughput for the evaluation of the GFP synthesis capacity of our reporter strains. In the case of classical shake flask system, no significant evolution of GFP synthesis have been observed, considering the reduced microbial growth period allowed by the system, whereas in the case of fed-batch operated mini-bioreactors, evolution of GFP synthesis, as well as GFP distribution among the microbial population, has been observed for three preselected strains (prpoS, puspA and posmC::gfp). More interestingly, a binary mode of expression has been observed in the case of the cultures carried out with the reporter strains for which GFP synthesis is under the control of the rpoS promoter which is induced under carbon limitation conditions. However, the generation of controlled glucose perturbations is relatively limited in this system and, in a second step fully automated bioreactor with a sclae-down strategy has been used to correlate the response of a prpoS::gfp strains with extracellular glucose perturbations. In the case of the culture performed in perturbed bioreactor (glucose intermittent feeding or glucose addition at the level of the recycle loop of a two-compartment scale-down bioreactor), the slowdown of the GFP synthesis resulting in the observation of a binary repartition of GFP content among the microbial population, has been observed. This observation led to the conclusion that the prpoS::gfp can be used as a biosensor for the validation of a fed-batch profile in industrial-scale bioreactors. [less ▲]

BACKGROUND: Lanoteplase (nPA) is a rationally designed variant of tissue plasminogen activator with greater fibrinolytic potency and slower plasma clearance than alteplase. METHODS AND RESULTS: InTIME (Intravenous nPA for Treatment of Infarcting Myocardium Early), a multicenter, double-blind, randomized, double-placebo angiographic trial, evaluated the dose-response relationship and safety of single-bolus, weight-adjusted lanoteplase. Patients (n=602) presenting within 6 hours of acute myocardial infarction were randomized and treated with either a single-bolus injection of lanoteplase (15, 30, 60, or 120 kU/kg) or accelerated alteplase. The primary objective was to determine TIMI grade flow at 60 minutes. Angiographic assessments were also performed at 90 minutes and on days 3 to 5. Follow-up was continued for 30 days. Lanoteplase achieved its primary objective, demonstrating a dose-response in TIMI grade 3 flow at 60 minutes (23.6% to 47.1% of subjects, P<0. 001). Similar results were observed at 90 minutes (26.1% to 57.1%, P<0.001). At 90 minutes, coronary patency (TIMI 2 or 3) increased across the dose range up to 83% of subjects at 120 kU/kg lanoteplase compared with 71.4% with alteplase. Thus, at this dose, lanoteplase was superior to alteplase in restoring coronary patency (difference, 12%; 95% CI, 1% to 23%). The early safety experience in this study suggests that lanoteplase was well tolerated at all doses with safety comparable to that of alteplase. CONCLUSIONS: Lanoteplase, a single-bolus, weight-adjusted agent, increased coronary patency at 60 and 90 minutes in a dose-dependent fashion. Coronary patency at 90 minutes was achieved more frequently with 120 kU/kg lanoteplase than alteplase. In this study, safety with lanoteplase and alteplase was comparable. InTIME-II, a worldwide mortality trial, will evaluate efficacy and safety with this promising new agent. [less ▲]

In human medicine, pulse oximetry is widely used to measure non-invasively and accurately the percentage of oxygen saturation of arterial haemoglobin (SpO(2)). Recently, pulse oximetry has been used in calves, but its accuracy has not been evaluated in newborn calves. The purpose of this study was to evaluate the accuracy of a pulse oximeter in newborn calves by comparing SpO(2) with arterial oxyhaemoglobin saturation (SaO(2)) obtained by use of a blood gas analyser. Fifty-five newborn calves were investigated from birth to 20 days old. Pulse oximetry readings and arterial blood samples were performed 5, 15, 30, 45, 60 min, 2, 3, 6, 12, 24 h and 1 and 3 weeks after birth. The transmission-type sensors of the pulse oximeter were fixed at the recommended site in the bovine species (at the base of the calf tail, where the skin had been shaved and was not pigmented) and arterial blood samples were withdrawn from the subclavian artery and analysed for SaO(2). Five-hundred paired data of SaO(2) and mean SpO(2)(mSpO(2)) were collected. Linear regression of the pooled data indicated a highly significant correlation of mSpO(2) with SaO(2) (r = 0.87;P< 0.001; mSpO(2) = 15.8 + 0.84 SaO(2)). The overall data bias value was positive (+2.1%), which indicated that the pulse oximeter tended to overestimate the SaO(2). The bias value for each SaO(2) category tended to become higher for lower ranges of SaO(2). Precision was also lower when SaO(2) values were low. The lower the SaO(2) value, the higher the positive bias (overestimation) and the lower the precision. These results suggest that pulse oximetry provides a relatively accurate non-invasive, immediate and portable method to monitor SaO(2) and to evaluate objectively the pulmonary function effectiveness in newborn calves during their adaptation to extra-uterine life.

Inappropriate seizure management may result in high morbidity and mortality. We assessed the adherence of health professionals in southern Rwanda to a national protocol for pharmacological management of seizures in children. A questionnaire featuring a 5-year-old child with generalized prolonged seizures was administered. The questions focused on the choice of initial treatment and the sequence of management following failure of the initial treatment choice. Benzodiazepine was chosen as initial therapy by 93.7% of physicians and 90.9% of nurses. Only 49.2% of physicians and 41% of nurses would repeat the initial treatment in case of failure of the first dose and 47% of doctors would wait 30 min to intervene. In case of refractory status epilepticus, 34% of physicians would give three doses of benzodiazepine, whereas 19% did not know what to do. These results suggest poor adherence to national protocol.

This study aims at the analysis of the utilization of an electronic nose (e-nose) to serve as a specific monitoring tool for anaerobic digestion process, especially for detecting organic overload. An array of non specific metal oxide semiconductor gas sensors were used to detect process faults due to organic overload events in twelve anaerobic semi-continuous reactors of 1.8 L. Three different load strategies were followed (i) a cautious organic load (1.3 gVS•L-1•day-1); (ii), an increasing load strategy (1.3 to 5.3 gVS∙L-1•day-1) and (iii) a cautious organic load with load pulses of up to 12 gVS•L-1•day-1. A first monitoring campaign was conducted with three different substrates : sucrose, maize oil, and a mix of sucrose/oil during 60 days. The second campaign was run with dry sugar beet pulp during 45 days. Hotelling's T²-value and upper control limit to a reference set of digesters fed with a cautious OLR (1.3 gVS•L-1•day-1), was used as indirect state variable of the reactors. Overload situations were identified by the e-nose apparatus with Hotelling’s T²-values at least 4-times higher in magnitude than the upper control limit of 23.7. These results confirmed that the e-nose technology appeared promising for online detection of process imbalances in the domain of anaerobic digestion. [less ▲]
