Méthode largement employée en matière d’évaluation d’entreprise, l’analyse dite comparative s’appuie sur une estimation de la valeur des entreprises selon un multiple de leur agrégat financier. Aussi appelée ‘méthode des pairs’, les multiples sont définis sur base d’un échantillon d’entreprises considérées comme comparable en termes de croissance et de risque. Le secteur est généralement retenu en pratique comme critère sous-tendant la croissance et le profil de risque opérationnel de l’entreprise. L’analyse menée dans cet article démontre l’importance des fondamentaux tels que la croissance, le risque et le taux de distribution des bénéfices dans la définition des pairs et donc de la valeur des entreprises. Sur base d’un échantillon des 100 entreprises cotées sur l’EURONEXT, entreprises les plus capitalisées et liquides, l’étude met en évidence un impact différencié de ces déterminants selon les conditions économiques. Les conséquences de notre analyse sont multiples. Premièrement, notre étude témoigne de l’importance des variables telles que le profil de risque et les perspectives croissance pour la sélection des pairs. Notre approche permet par ailleurs d’appréhender la valeur des entreprises sur base de leurs propres fondamentaux, corrigeant ainsi la méthode des multiples ‘sectoriels’ pour les différences qui subsistent au sein des sous-jacents de la valeur. Finalement, cet article nourrit une discussion quant à l’impact de la finance comportementale sur la valorisation de l’entreprise de par l’impact différencié des fondamentaux sur la valeur des entreprises au cours du temps.

This study analyses the choice determinants of the population for conventioned polyclinics through a survey of the behavior of families in a representative sample of 1000 households in the health zones of Kinshasa, Congo in 1997. For the last episode of illness, the respondents resorted to 7 types of care: health centre (37%), the private health clinic (26.5%), the pharmaceutical self-medication (23.9%), the traditional practitioner (21%), the traditional self-medication (16.9%), the conventioned polyclinic (16.7%) and a referral hospital (10.4%). Past logistics have shown more resort to the conventioned polyclinic rather than another type of health structure (p< 0.05) when looking for a doctor or the existence of “convention” between the polyclinic and the household. On the other hand, concern about geographical proximity in relation with the household’s residence calls for using the private clinic. When looking for quality of care, reasonable prices and of varied services, patients resort to health centre rather than other type of care structure (p=0.05). Those who have been looking for a solution to a particular type of disease resort primarily to the traditional practitioner. In conclusion, the results of this study show that if people choose the conventioned polyclinic, it is because of the presence of the doctor. The presence of the doctor in the structure of health is a great asset to the acceptability of the first level of primary health care in Kinshasa. This study suggests that it would no doubt be beneficial to integrate the non-official private care structures into the primary health care system, as far as they can use a doctor. In order that the traditional practitioner might play an important and complementary role in the realization of primary healthcare, even in urban areas, it is suggested to explore the possibility of promoting sites of communication. Moreover, considering the low buying power of the city’s inhabitants and the previous existence of solidarity and the structure of health insurance tontines, the ‘conventions’ providing relief of health care costs, under the leadership of the local communities, should be integrated into the organization of the urban health system.

This study analyses the choice determinants of the population for health centres through a survey of the behaviour of families in a representative sample of 1,000 households in the health districts of Kinshasa, Congo in 1997. For the most recent episode of illness, the respondents turned to seven types of care: the health centre (37%), private dispensaries (26.5%), self-medication through a pharmacy (23.9%), traditional practitioner (21%), traditional self-medication (16.9%), private outpatients' clinic (16.7%) and a reference hospital (10.4%). Past logistics have shown that patients resort to a health centre rather than another type of care structure (P = 0.05) when looking for quality care, reasonable prices and the availability of varied services. On the other hand, concern about the geographical proximity in relation to the family's residence calls for using the private dispensary. When looking for a doctor or the existence of a 'convention', families are more inclined to choose a private officially recognized outpatients' clinic. Those who had been looking for a solution to a special type of illness opted primarily for a traditional practitioner. In conclusion, the results of this study show that if people choose the care offered by health centres, it is because they judge it to be of good quality. The integrated care offered by the same technician, with a required training, is a major asset in the acceptability of the first line of primary health care in Kinshasa. This study suggests that it would no doubt be beneficial to integrate non-official private care structures into the primary health care system, as far as it is possible for them to achieve a level of quality comparable to that of the health centres. In order that the traditional practitioner might play an important complementary role in the realization of primary health care, even in urban areas, the possibility of promoting sites of communication should be studied. Moreover, considering the weak buying power of the city's inhabitants and the previous existence of tontines out of solidarity, the 'conventions' providing relief of health care costs, under the leadership of the local communities, should be integrated into the organization of the urban health system.

This study analyses the determinants of choice of the populations for the traditional practitioner through a survey of behavior of families in a representative sample of 1000 household in the health zones of Kinshasa, Congo in 1997. For the last episode of illness, the respondents resorted to 7 types of care: health centre (37%), the health clinic private (26.5%), pharmaceutical self-medication (23.9%), traditional healer (21%), traditional self-medication (16.9%), the associated polyclinic (16.7%) and a referral hospital (10.4%). Past logistics have shown more resort to the health centre (p<0,05) when looking for the quality of care. So, when looking for the presence of a doctor and the existence of a ‘convention’ with the household people resorts to the conventional polyclinic. On the other hand, concern about the geographical proximity in relation with the household’s residence, people calls for using the private clinic. When looking for the existence of the polyvalent services and acceptable prices, the health centre is resorted rather than other health structures. People who searched for a solution to a particular type of disease chose primarily the traditional practitioner. In conclusion, the results of this study show that if people choose the traditional practitioner, it is because they consider him as the only appropriate for the type of concerned disease. The presence of a traditional practitioner, “specialized” in the health care of specific types of disease, in the structure of health is a great asset to the acceptability of the first level of primary health care in Kinshasa. This study suggests that the traditional practitioner can play a complementary role in the realization of primary healthcare, even in urban areas. It is important to study the possibility of integrating the traditional health care in the minimum package of activities. Moreover, considering the low buying power of the city’s inhabitants and the previous existence of solidarity and the structures of health insurance tontines, “convention” providing reduction of health care cost, under the leadership of the local communities, should be integrated into the organization of the urban health care system.

La prévention de l'hypertension artérielle essentielle figure parmi les préoccupations majeures en matière de santé publique. Si, à l'heure actuelle, les causes de l'hypertension artérielle essentielle sont encore imprécises, il est vraisemblable que son orgine est multifactorielle. D'autre part, quelques études épidémiologiques ont suggéré que cette pathologie s'installerait dans l'adolescence, voire dans l'enfance, pour s'aggraver progressivement et se manifester cliniquement à l'âge adulte.

This study investigated the determinants of financial inclusion for small scale farmers by focusing on the access to formal and informal agricultural credits in the Southern Province of Rwanda. Data were collected from 310 farmers from Huye and Nyamagabe districts through an open-ended structured questionnaire and analysed using the binary logistic regression method. The major findings, on one hand, showed that among the requested and approved agricultural loans, 87.2% and 12.7% were from informal and formal financial institutions respectively. Among those who accessed agricultural credits, 59.7% were from Huye and 40.3% from Nyamagabe. On the other hand, it was revealed that the household characteristics and the community attributes are the most important determinants. Those household characteristics include household income and expenditure, Ubudehe socio-economic category of the household, off-farm employment and the size of the land owned by the household whereas community attributes involve residence area, transport and informal financial services availability. Regarding farmer characteristics, the education level was found to be the only factor affecting the smallholder farmers' access to agricultural credit. In light of the findings, it was recommended to conduct sensitization sessions focusing on the importance of agricultural credits for smallholder farmers especially in the areas with high level of poverty. In addition, there is need to work on alleviating the formal agricultural credits access barriers, and to conduct a study on the dynamics of informal and formal agricultural credits up take and usage by smallholder farmers to explore all dimensions of financial inclusion in the study area.

AIM: Patients with asymptomatic aortic stenosis (AS) and abnormal haemodynamic responses to exercise testing are at increased risk of cardiac events. This study assesses the Doppler echocardiographic determinants of a positive exercise test in a cohort of asymptomatic patients with AS. METHODS AND RESULTS: One hundred and twenty-eight patients with AS underwent quantitative Doppler echocardiographic measurements at rest and during exercise test. Of these patients, 60 had an abnormal response to exercise. Two independent determinants of an abnormal exercise response were selected in multivariate analysis: a larger increase in mean transaortic pressure gradient (P = 0.00014) and a limited contractile reserve-latent left ventricular dysfunction-as indicated by smaller changes in ejection fraction (P = 0.0002). Limiting symptoms were associated with greater increase in mean transaortic pressure gradient, smaller changes in systolic blood pressure and a lower ejection fraction at peak exercise. The increase in pressure gradient was associated with smaller exercise-induced changes in aortic valve area and in ejection fraction and new or worsening mitral regurgitation during exercise. CONCLUSION: Abnormal responses to exercise in asymptomatic AS patients are mediated by a larger increase in mean transaortic pressure gradient and/or a limited contractile reserve characterized by an inadequate increase in ejection fraction at exercise.

Charitable giving is a research topic that has largely been addressed in the U.S.-context. However, there exist only very few studies on Belgian donating behavior. This paper aims to fill this gap using a combination of fiscal, demographic and political data. OLS regressions and Fixed effects regressions are performed and show a positive effect of age and income on the probability to donate. In addition, age and income increase the average donation amount, whereas gender and declaring jointly tend to decrease it. Further, the region and the political party to which belongs the mayor of the municipality in which one lives also affect the likelihood of charitable giving and the donated amount. This paper has implications both for researchers and charity practitioners. The latter are likely to pay attention to the factors that increase the probability to donate and the average donated amount, especially in times of economic crises as charities may rely less and less on the state to cover their financial resource needs.

OBJECTIVES: We sought to examine the determinants of exercise-induced changes in ischemic mitral regurgitation (MR) in patients with left ventricular (LV) dysfunction. BACKGROUND: In the post-myocardial infarction (MI) phase, ischemic MR contributes to worsening of symptoms and of LV dysfunction. METHODS: In this study, 70 patients in the chronic, post-MI phase, with LV ejection fraction <45% and at least mild MR, underwent semi-supine exercise Doppler echocardiography. The effective regurgitant orifice (ERO) of MR was quantified at rest and during exercise. Exercise-induced changes in ERO were compared with changes in mitral deformation and in local and global LV remodeling. RESULTS: The wide range of exercise-induced ERO changes that were observed was unrelated to the degree of MR at rest (r = 0.20). Effective regurgitant orifice changes correlated best with changes in mitral deformation (i.e., differences in systolic mitral tenting area, systolic annular area, and coaptation height) (p < 0.0001). Posterior displacement of the papillary muscles was associated with larger changes in the ERO in both infarct groups. In patients with inferior MI, a decrease in the ERO was related to improvement in wall motion (r = 0.68). The independent predictors of ERO changes during exercise were changes in systolic annular area for all infarct categories, in tenting area and wall motion score in the global population and those with inferior infarction, and in apical displacement of mitral leaflets for patients with anterior MI. CONCLUSIONS: The degree of MR at rest is unrelated to exercise-induced changes in EROs, which are related to those in local LV remodeling and in mitral deformation but not those in global LV function.

BACKGROUND: Exercise-induced pulmonary arterial hypertension (EIPH) in systemic sclerosis (SSc) has already been observed but its determinants remain unclear. The aim of this study was to determine the incidence and the determinants of EIPH in SSc. METHODS AND RESULTS: We prospectively enrolled 63 patients with SSc (age 54+/-3years, 76% female) followed in CHU Sart-Tilman in Liege. All patients underwent graded semi-supine exercise echocardiography. Systolic pulmonary arterial pressure (sPAP) was derived from the peak velocity of the tricuspid regurgitation jet and adding the estimation of right atrial pressure, both at rest and during exercise. Resting pulmonary arterial hypertension (PH) was defined as sPAP >35mmHg and EIPH as sPAP >50mmHg during exercise. The following formulas were used: mean PAP (mPAP)=0.61xsPAP+2, left atrial pressure (LAP)=1.9+1.24xleft ventricular (LV) E/e' and pulmonary vascular resistance (PVR)=(mPAP-LAP)/LV cardiac output (CO) and slope of mPAP-LVCO relationship=changes in mPAP/changes in LVCO. Resting PH was present in 3 patients (7%) and 21 patients developed EIPH (47%). Patients with EIPH had higher resting LAP (10.3+/-2.2 versus 8.8+/-2.3mmHg; p=0.03), resting PVR (2.6+/-0.8 vs. 1.4+/-1.1Woods units; p=0.004), exercise LAP (13.3+/-2.3 vs. 9+/-1.7mmHg; p<0.0001), exercise PVR (3.6+/-0.7 vs. 2.1+/-0.9 Woods units; p=0.02) and slope of mPAP-LVCO (5.8+/-2.4 vs. 2.9+/-2.1mmHg/L/min; p<0.0001). After adjustment for age and gender, exercise LAP (beta=3.1+/-0.8; p=0.001) and exercise PVR (beta=7.9+/-1.7; p=0.0001) were independent determinants of exercise sPAP. CONCLUSION: EIPH is frequent in SSc patients and is mainly related to both increased exercise LV filling pressure and exercise PVR. [less ▲]

Objective: Our goal was to identify the magnitude of gastro-protective drugs (GPDs) co-prescription and the profile of patients who received GPD co-prescription, during nonsteroidal anti-inflammatory drugs (NSAIDs) treatment in a "real life setting" of primary care practice. Methods: A pragmatic prospective 6-month survey of 2197 new takers of nonselective NSAIDs, selected and followed by general practitioners (GPs) on the bias of their usual standards of care. Results: Forty-seven percent of our survey population used at least one GPD during the 6-month follow-up. No difference was identified between piroxicam, diclofenac, ibuprofen, meloxicam and nimesulid for the GPD co-prescription. Besides the presence of gastro-intestinal (GI) symptoms, previous use of GPD, previous occurrence of GI disorders and increase in age are the most prominent predictive factors of GPD use during NSAID treatment. When adjusted for other risk factors, co-prescription of GPD was significantly increased in patients aged 55 years and above (odds ratio (OR): 1.29, 95% confidence interval (Cl): 1.01-1.64) with no further increase in the co-prescription in older subjects. Conclusion: Patients above 55 years with previous history of GI symptoms or GPD use are more likely to benefit from cytoprotective medications. (C) 2006 OsteoArthritis Research Society International.
