Valvular heart diseases during pregnancy are complex with symptoms likely to affect patient’s life quality, and endanger both mother’s and child’s life. Our survey aims at studying the combination of valvular heart diseases with pregnancy at University Hospital Yalgado Ouedraogo. This study was a cross-sectional study conducted from January 1st, 2015 to March 31st, 2016 in the delivery room of gynecology and obstetrics department. Inclusion criteria were: the presence of acquired and known valvular heart diseases followed-up or not; suspected valvular heart disease confirmed by a Doppler echocardiography and patient’s consent to take part to the study. Twelve patients were involved in the study. The average age was 27.5 ± 3.9 years (extremes of 21 and 34 years). The average gestational age at the delivery time was 35 ± 4.7 weeks of amenorrhea with extremes reaching 25 and 39 weeks. None of the study patients were previously followed-up and treated for valvular heart diseases before pregnancy. Mitral disease was found among four patients. Seven cases had vaginal delivery. Two cases of spontaneous abortion were observed. We had seven hypotrophy newborns with an average weight of 2360 g at birth. Two patients suffering from congestive heart failure with a full type arrhythmia by atrial fibrillation were hospitalized in cardiology department. No death was reported during our study. Rheumatic valvular diseases are common among pregnant women. The cardiologist should plan pregnancies of patients suffering from valvular heart diseases. Treatment of those patients goes through the prevention of acute rheumatoid arthritis including a joint collaboration between cardiologists and gynecologists.

Introduction: This study aimed at describing the socio-economic, diagnostic, and progressive features of patients evacuated thanks to philanthropic sponsors. Patients and methods: all evacuated patients, contacted through the phone and interviewed, were included in the study. A questionnaire helped in collecting data which were analyzed through the software Epi-Info (version 7). Outcomes: A total of 63 patients out of 134 were included in the study among which there are 22 adults and 41 children. The sex-ratio was 1.30. Patients living in Ouagadougou accounted for 79% of cases. The children’s average age at evacuation was 3.58 ± 3.86 years against 27.52 ± 12.54 years for adults. Ventricular septal defects among children (58.53%) and mitral valve diseases among adults (72.72%) were the main diagnoses at the time of evacuation. The average fall was 47 months for children, and 54 months for adults in the post-operative period. 68% of adults had an income below 50,000 FCFA per month. The evacuation average cost was estimated at 21,083,000 FCFA per patient, corresponding to 2,825,122,000 FCA over 10 years. Each adult patient spent an average of 15,000 FCFA per month for the follow up, against 8725 FCFA for children. 16% of patients were lost of sight in the post-operative. Conclusion: Philanthropic sponsors significantly contribute to the management of cardiac patients, and their efforts should be supported by a better monitoring. Setting-up cardiac surgery and interventional cardiology in Burkina Faso are required to address these health shortcomings.

Objective: Our study aimed at assessing the quality of life (QoL) of patients treated for chronic heart failure (HF), and analyzing the impact of certain factors on that QoL, in the cardiology department of Yalgado Ouédraogo University Hospital of Ouagadougou. Means and Method: It was a descriptive cross-sectional study, performed over a six-month period from May to October 2016. In the study, patients with age over 18 years were included, followed up for chronic HF for at least six months in the outpatient unit, from January 1st to December 31st 2015. The questionnaire “Minnesota Living with Heart Failure” was used to assess the QoL. Results: Two hundred and four patients were enrolled. Most of them were living in Ouagadougou (82.8%). Sex ratio was 0.98, and mean age was 56.06 16.37 years. The mean overall QoL score was 17.8 16.5. QoL was considered good in its three dimensions, in more than 70% of patients. Looking at the mean scores, the male patients, the patients living in rural and semi-urban areas, the patients with impaired left ventricular ejection fraction and those with severe or end-stage renal failure had significant QoL impairment. Multiple linear regression reported significant correlation between QoL impairment and the following factors (p value < 0.05 for all variables): marital life, number of hospitalizations for acute HF, and NYHA functional stage. Conclusion: Marital life, number of hospitalizations for acute decompensation, and NYHA functional stage were predictive factors of QoL impairment. MLHF questionnaire should be commonly used to assess the efficiency of HF management. Self administration instead of assistance in filling the questionnaire, could insure a more objective valuation of QoL.
Long-Term Re-Admission after Hospital Discharge in Patients Admitted with Acute Heart Failure: The Prognostic Value of the Six-Minute Walk Test Distance  [PDF]

Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104841
Background: We sought the value of the six-minute walk test distance in predicting re-admission in patients with chronic heart failure (CHF) in the department of cardiology, Yalgado Ouédraogo University Hospital, Ouaga-dougou, Burkina Faso. Methods: We did a prospective observational study in patients hospitalized with acute decompensated heart failure and who underwent a 6-minute walk test (6-MWT) at their discharge from hospital. The primary end-point was hospital re-admission for heart failure de-compensation. Results: Sixty-one patients (52% females, mean age 46.9 ± 14.1 years, mean left ventricular ejection fraction 32.4 ± 8.2%, mean 6-MWT distance 336.3 ± 65 meters) were followed-up for a 277.6 ± 129.8 days’ period. Twenty-one patients (45.3 percent person-years) were re-admitted. Re-admitted patients had shorter 6-MWT distance (p = 0.007) and were more likely to die than those who were not re-admitted (RR = 1.72, 95% CI = 1.13 - 2.62, p = 0.003). Multivariate Cox regression analysis showed that re-admission was independently predicted by shorter 6-MWT distance (p < 0.001), New York Heart Association class III (p = 0.03), older age p = 0.03) and lower LVEF (p = 0.02). Conclusion: Distance covered during the six-minute walk test is an independent predictor of hospital re-admission for heart failure decompensation in patients with chronic heart failure.

Abstract: Radial nerve injuries in displaced extension-type supracondylar humeral fractures in children are well known. Entrapment in fracture of radial nerve is uncommon and rarely evocated in literature. We report two similar cases in the mechanism of injury, the clinical findings and the treatment and propose therapeutic guidelines.

Natural Resources (NR) , 2014, DOI: 10.4236/nr.2014.54012

The objective of this paper is to propose a conceptual framework stimulating the sustainable management of natural resources in Central Africa. Based on the forest resources, we show how good identification and allocation of property rights strengthen the joint management of forest resources. Cameroon is selected as an example, since the country represents one of the most forest-intense areas in Africa. In doing so, we first evaluate the performance of institutions in fostering sustainable forest management. Second we show how good elaboration and allocation of property rights may contribute to improving efficiency in forest management. Using the New Institutional Economic (NIE) theory we provide an outline of the potential relationships between forest management and property rights allocated to stakeholders involved in forest exploitation. Finally we provide two forms of institutional structures that could improve forest management efficiency: public-private partnership and multi-stakeholder management approaches. Public-private partnerships are joint project management processes operated by both private businesses and public entities in order to combine public prescriptive mechanisms with private operational roles. Multi-stakeholder management approach is also a co-management initiative combining public entities, private actors and local population to increase the involvement of local dwellers living in forest areas in the decision process.

Determination of an Equivalent Loading Circle Which May Represent the Loading of the Dual Wheels  [PDF]

Open Journal of Civil Engineering (OJCE) , 2018, DOI: 10.4236/ojce.2018.82018
Abstract: This work aims to look for a simplifying surface that can represent the effect of the dual wheels on the variation of the stress and deformation state prevailing during the passage of traffic loads. This was facilitated by the results of Thiam (2016) [4] obtained on the distribution of the vertical contact stress in the space described by the dual wheels. The analysis of the results of this study, on all the loading circles considered, shows that the radius loading circle equal to 0.181 m makes it possible to most probably represent the effect of the dual wheels. With this new surface, the effect of the dual wheels can be determined in 2D. The choice of this load is confirmed by a study in case of overload. Thus, the single axle with dual wheels is represented by a simplified diagram equipped on each side by a disk of radius 0.181 m. These results are obtained using a numerical simulation under Cast3M with a gravelly lateritic pavement.
Taking into Account the Effect of Dual Wheels on the Behavior of Lateritic Gravelly Pavements  [PDF]

Abstract: The representation in the three-dimensional space of the physical model symbolized by the application of the pairing of the wheels described by 2 disks with a radius of 0.125 m and a 0.375 m spacing has the advantage of more accurately simulating the loading. In most cases, the assumption of a uniform distribution of loading on the circular surface is considered. In order to determine the effect of dual wheels, this research proposes a new approach to the distribution of vertical contact stress in three-dimensional space with loading on the circular surface. This allowed evaluating the maximum deformation on the space described by the dual wheels. The results showed that vertical deformation is maximum at the center of each circular surface. The distribution of the vertical contact stress is non-uniform on the circular footprint and has a significant influence on the deformation of the pavement at the level of the bituminous layer. The impact assessment of the twinning reveals that the dual wheels load causes less damage than that of a single wheel. These results are obtained by means of a numerical simulation under Cast3M with a gravitational lateritic pavement.

Introduction: Vasopressive amines are frequently used in cardioology. The aim of our work was to evaluate the practical modalities of use of amines in the cardiology department of University Hospital Yalgado Ouédraogo. Patients and Methods: We conducted a prospective observational study for 6 months, from 01 June to 31 November 2013, including all patients treated with vasopressive amines. We were interested in the different clinical pictures, the indications, the choice of amines, and the practical application of the treatment. Results: Fifty patients were included in the study; the mean age was 58 ± 17.6. The sex ratio was 0.85. Hypertensive heart disease was the underlying cardiac disease in 34% of cases. A known chronic heart failure was observed in 62% of cases. Clinical admission tables were dominated by overall heart failure (74%). Vascular collapse (38%) and shock (36%) were the main indications of treatment. Severe alterations in left ventricular systolic function were found in 74% of cases. Dobutamine was the amine of choice (90%). The average time to start treatment was 96.32 minutes (range 15-660 minutes). The time to relay between syringes was more than ten minutes in 72% of the cases, and the nurses’ unavailability was the main cause. Monitoring was manual in almost all cases. The average duration of treatment was 6.64 days. Treatment-related incidents were observed in 26% of cases. The intra-hospital mortality of patients with amines was 48%. Conclusion: The indications of vasopressive amines in the cardiology department are close to the international recommendations. But this treatment suffers in its practical application. The duration of treatment remains excessive but is explained by the lack of therapeutic alternative.
Hardy and Hardy-Sobolev inequalities on Riemannian manifolds

Mathematics , 2015,
Abstract: Let $ (M,g) $ be a smooth compact Riemannian manifold of dimension $ N \geq 3 $. Given $p_0 \in M$, $\lambda \in \mathcal{R}$ and $\sigma \in (0,2]$, we study existence and non existence of minimizers of the following quotient: \begin{equation}\label{Paper Equation} \mu_{\lambda,\sigma}=\inf_{u \in H^1(M)\setminus \lbrace0\rbrace} \frac{\displaystyle\int_M |\nabla u|^2 dv_g -\lambda \int_M u^2 dv_g }{\biggl(\displaystyle\int_M \rho^{-\sigma} |u|^{2^*(\sigma)} dv_g\biggl)^{2/2^*(\sigma)}}, \end{equation} where $\rho(.):=dist(p_0,.)$ denoted the geodesic distance from $p \in M$ to $p_0$. In particular for $\sigma=2$, we provide sufficient and necessary conditions of existence of minimizers in terms of $\lambda$. For $\sigma\in (0,2)$ we prove existence of minimizers under scalar curvature pinching.
