Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103478
Background: Acute heart failure (AHF) is a major public health issue. Our objective was to study its clinical pattern and outcome in a reference hospital in Cameroon. Methods: This was a retrospective observational study, including any patient hospitalized for AHF, diagnosed based on clinical and/or ultrasound evidence, in the Cardiology Department of the Yaounde Central Hospital during a period of 3 years from January 1st 2013 to March 30th 2016. Data were entered and analyzed using the statistical software Epi info version Results: A total of 148 patients with AHF were included over a total of 445 admissions. It accounted for 33.3% of admissions. The average age was 61.46 years. The female-male sex ratio was 1.34. The main cardiovascular risk factors were hypertension (54.79%). Dyspnea on exertion was the most prevalent symptom (86%). Hypertensive AHF was the most represented etiopathogenic entity in the series. The main electrocardiographic abnormality found (27.61%) was atrial fibrillation. Cardiomegaly was found in 44.76% of the cases. Hyponatraemia and anemia were found in about a quarter of the cases. On echocardiography, 49.61% of patients had heart failure with a preserved ejection fraction. The main findings were hypertensive heart disease (30.16%) and dilated cardiomyopathy (28.57%). Concerning the management, the most commonly used drugs on admission were loop diuretics; and on discharge, were ACE inhibitors/angiotensin II receptor blockers. Intrahospital mortality was 18.45%. Conclusion: AHF at the Yaounde Central Hospital occurs with severe clinical presentation, complicated by high intra-hospital mortality. Hypertension plays a predominant role both in its onset and in the underlying chronic cardiac involvement.

Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104247
Background: There is paucity of data on congestive heart failure (CHF) in the intensive care unit in our setting. This study aimed to provide a better knowledge of pattern and outcome of CHF in the intensive care unit of the Yaounde University Teaching Hospital. Methods: We carried out a descriptive and retrospective study over a period of 21 months. We collected sociodemographic, clinical, paraclinical outcome and medication data from patients’ files. Statistical analysis was done using SPSS Version 20.0 Software. Results: We included 24 patients in this study. CHF represented 6.7% of admissions in the ICU. The sex ratio was 1. The mean age was 62 ± 16 years. The most frequent comorbidity was hypertension (50%). Most of the patients (84.6%) were classified Stage IV according to the NYHA. Dyspnea on exertion was the most frequent symptom (87%), while bilateral fine crackles were the main findings on physical exam (75%). Atrial fibrillation was the most frequent abnormality on ECG (53.3%), and most of the patients had a severe decrease in LVEF (87.5%). The mean duration of hospital stay was 10 days. In hospital, mortality was 25%, and this was significantly associated with mean blood pressure < 80 mmHg (p = 0.045). Conclusion: Clinical patterns of CHF in the ICU differed from those found in standard hospital care. Mean blood pressure was significantly associated with outcome. These characteristics should be taken in account while planning the treatment of these patients.

World Journal of Neuroscience (WJNS) , 2014, DOI: 10.4236/wjns.2014.45044
Abstract: Background and Objectives: Cerebro-vascular accident or stroke constitutes a major challenge in sub-Saharan Africa. In Cameroon, basic epidemiologic data are not routinely available. Aims: The aim of this study was to determine the type, the associated risk factors, time to admission, the clinical presentation and the case fatality of stroke at the Douala General Hospital (DGH) in Cameroon. Methods: A cross-sectional study was performed from January 1, 2010 to December 31, 2012 at the neurology and intensive care units of the DGH. All patients above 15 years of age with a diagnosis of established stroke were enrolled. For each patient, socio-demographic, clinical and paraclinical data were recorded as well as the duration of hospitalization and the case fatality. Results: In all, 325 patients were enrolled with males constituting 68.1% and general mean age of 58.66 ± 13.6 years. The mean initial consultation delay was 47.36 ± 18.48 hours. The majors cerebro-vascular risk factors were hypertension (81.15%), chronic alcohol consumption (28.3%), diabetes mellitus (20.61%), obesity (18.15%), cigarette smoking (16%), dyslipidemia (8.9%) and atrial fibrillation (3.07%). Ischemic stroke accounted for 52% of cases while 48% were hemorrhagic. The mean duration of hospitalization was 8.58 ± 6.35 days with a case fatality rate of 26.8%. Septic conditions appeared to be the leading cause of death accounting for 35.6% of cases. Conclusion: Stroke in the DGH is associated with a high case fatality rate and hypertension remains the number one risk factor. There is a clear and urgent need for public health authorities to reinforce measures for the control of modifiable stroke risk factors.

Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103384
Background: Atrial fibrillation (AF) is the most frequent sustained arrhythmia. The prevalence is increasing with that of other cardiovascular risk factors in our low-income setting. It is potentially serious due to the associated complications. Few data exist on the epidemiology of AF in Sub-Saharan Africa (SSA). Methodology: We carried out a cross-sectional study between 2005 and 2009 in the Cardiology Unit of the Douala General Hospital. Patients were adults ≥ 18 years of both sex, who had an ECG diagnosis of Atrial Fibrillation and a comprehensive investigation of the cause of AF. Results: A total of 2581 patients were seen in this unit, of whom 182 (7.1%, [95%: 6.1-8.1]) had AF. Their mean age was 59.2 ± 15.4 years, and there were 100 (58.2%, [95% CI: 51-65.6], p = 0.002) females. Hypertension was the most frequent risk factor (77.3%, [95% CI: 70.3-82.8]), and 163 (95.3%, [95% CI: 90.7-97.8]) of the patients were symptomatic. Hypertensive heart disease (45.6%, [95% CI: 38.3-53.1]), idiopathic dilated cardiomyopathy (19.3%, [95% CI: 14.1-25.9]), and valvular heart disease (16.4%, [95% CI: 11.6-22.6]) were the main etiologic factors of AF. The most frequent complications were heart failure seen in 77 (45%, [37.8-52.5]) and ischemic stroke in 27 (15.5%, [95% CI: 11.1 - 22]) of patients. Digoxine was prescribed in 121 (70.8%, [95% CI: 63.6-77.1]) patients to control heart rate, while amiodarone was prescribed in 67 (29.2%, [95% CI: 32.2-46.7]) patients to revert to sinus rhythm. No electrical cardioversion was carried out. Aspirine was prescribed in 119 (69.6%, [95% CI: 62.3-76]) patients, and anti-vitamin K in 53 (30.4%, [95% CI: 24.5-38.3]) patients. Conclusion: Atrial fibrillation was seen in seven percent of patients in the Cardiology Unit of this low-income setting. Patients were relatively young compared with high income settings. Hypertension, idiopathic dilated cardiomyopathy, and valvular heart disease were the main causes. Rate control was the main treatment strategy. Oral anti-coagulants were less frequently used.

World Journal of Cardiovascular Diseases (WJCD) , 2018, DOI: 10.4236/wjcd.2018.82013
Abstract: Background: Cardiovascular emergencies have become a public health problem with a high burden in low-income settings. This is due to the high rates of cardiovascular risk factors that are fast reaching epidemic?proportions. There is paucity of data on cardiovascular emergencies to guide repost strategies in our setting. Our aim was to determine the clinical presentation and outcome of cardiovascular emergencies at Yaounde Emergency Center.?Methods: We carried out this cross-sectional study between June 2015 and May 2017. We included all patients with confirmed cardiovascular emergency. We consecutively collected data on socio-demography, symptoms on admission, past history, clinical findings, and final diagnosis at discharge or in the event of death. Results: Of the 8285 patients admitted for medical emergencies, 388 (4.7%) were cardiovascular emergencies. Their mean age was 59.5 ± 13.8 years, and 59% were males. The Medical Emergency Aid Service was the means of transporting 4% of patients. The median time of arrival at the hospital was 48 hours. Symptoms on admission were mainly weakness of a limb (43.8%), and altered consciousness (33.5%). The most common cardiovascular emergencies were ischemic stroke (30.9%), hypertensive emergency (21.4%), and hemorrhagic stroke (16.5%). The most common comorbidity was diabetes (21.9%). The death rate in the 24 - 72 hours was 14.4%. The causes of death were hypertensive emergency (35.7%), and hemorrhagic stroke (30.3%). Conclusion:
The Impact of FDIs Flows on the Nigerien Economic Growth

International Journal of Financial Research , 2011, DOI: 10.5430/ijfr.v2n2p16
Abstract: Niger, since the 70s has always adopted an approach that makes the IDE a major component of its development plan. It `s so, a series of measures have been taken to make the country more attractive to Foreign direct investment FDI This policy has guaranteed the country a few annual flow between the period 1970 to 2008.The aim of this paper is to try to study the impact of FDI on economic growth in Niger. Observe the literature study on FDI in Niger, however, it is also becoming important to see the between FDI and economic performance since it has not been addressed specifically yet. While it is still unclear of whether there is any relationship between FDI and economic growth in Niger, especially as regard to the causality within the relationship. The theory and the current empirical literature on the relationship between FDI and growth have provided ambiguous results. Using VAR (Vector Autoregressive) model, this paper explores the causal relationship between FDI and economic growth for the period 1970-2008 in Niger. With in the Granger causality framework, this study finds a long-term relationship between FDI and economic growth. This finding is a long-term relationship between variables but failed to establish the direct correlation between each variable. This can be explained by the fact that low volume flows of FDI in Niger have major consequences on the economic system, particularly on employment, inflation and GDP. More, this weakness is emphasized by the insignificance of the volume of capital flows (domestic and foreign) circulating in the Nigerian economy and domestic savings.
Choix linguistique et modernité islamique au Cameroun Linguistic choices and Islamic modernity in Cameroon: the case of Fulfulde and Arabic.

Revue des Mondes Musulmans et de la Méditerranée , 2011, DOI: 10.4000/remmm.6012
Abstract: This paper discusses the interplay between Islam, Arabic and Fulfulde in Cameroon with regard to a dual relationship based on competition and cooperation. Language plays a predominant role in the relationship between the universality of the Islamic dogma and the contextualized interpretations of it. The exploration of the cross-currents of fulanization [Fulfuldization] of Arabic and Arabization of Fulfulde, the interference between the linguistic activism of Christian missions and Muslim militants and the relation between orality and writing shed light on the internal and external dynamics and on the modes of invention/reinvention of a certain modernity. The proponents of the Islamic tradition and the militants of modernity maintain a realistic relationship, translated at the linguistic level into mixing and mutual influences between Arabic and Fulfulde. Cet article aborde les questions de l’interface entre islam, langue arabe et fulfulde au regard d’une double relation de compétition et de coopération dans l’espace camerounais. à travers le rapport entre l’universalité du dogme islamique et les interprétations contextualisées de ce dogme, la langue joue un r le de premier plan. L’exploration des processus croisés de fulanisation de l’arabe et d’arabisation du fulfulde ainsi que les interférences entre l’activisme linguistique des missions chrétiennes et des militants musulmans et le rapport oralité/écriture éclairent sur les dynamiques tant internes qu’externes et sur les modalités d’invention ou/et de réinvention d’une certaine modernité. Au-delà des interférences entre langues, savoirs et pouvoirs et des situations de compétition au sein de la société musulmane et face aux églises et à l’état colonial puis postcolonial, au-delà des contingences, de l’instrumentalisation, du communautarisme et des enjeux qu’on imagine plus ou moins importants, les tenants de la tradition islamique et les partisans de la modernité entretiennent pour l’heure une relation somme toute réaliste dont l’issue, au plan linguistique, se déclinerait en termes de métissage et d’influences réciproques fécondes entre l’arabe et le fulfulde.

Introduction: The cold test is known as a predictor of essential hypertension. The hemodynamic response to this test has rarely been studied in black African adults. Black Africans also suffer cold stress. But whether they suffer it the same way as other populations is still to be determined. Equipment and Method: We studied the response of blood pressure (BP) during the cold test in 62 black normotensive adults and hypertensive Cameroonians aged between 21 and 59 years. Those with an increase in systolic blood pressure (SBP) > 20 mmHg and/or diastolic blood pressure > 15 mmHg were considered to be hyper-reactors. Results: SBP increased significantly in hyper-reactors compared with normo-reactors in both hypertensive and normotensive subjects (176 ± 20 vs. 154 ± 11, p = 0.01 and 148 ± 17 vs. 125 ± 11, p < 0.001, respectively) and this increment persisted up to two minutes after the end of the stress exposure although the difference was no more statistically significant. We found the same result for the DBP (111 ± 13 vs. 99 ± 10, p = 0.04 and 95 ± 11 vs. 81 ± 10, p = 0.001, respectively). However, the DBP stayed higher in hyper reactors compared to normal reactors in the normotensive group up to four minutes after cessation of the stress exposure. The recovery time of the baseline BP was considerably longer in hyper reactors compared with the normal reactors (2.1 ± 0.9 vs. 1.1 ± 0.4 minutes, p = 0.01 and 1.9 ± 1.0 vs. 1.3 ± 0.5 minutes, p = 0.03 respectively in hypertensive and normotensive). Conclusion: Hyper reactors in the cold test have a more pronounced and prolonged reactivity. They are thus predisposed to develop hypertension.

Abstract: Despite existing policies on training health professionnels in essential newborn care (ENC), neonatal mortality still remains high in Mali. Our work aimed to assess the level of knowledge of health staff about ENC. Material and methods: From March 20th to April 20th, 2016, we interviewed newborn care providers at the six reference health centers and the Gabriel Touré University Hospital Center in Bamako. Results: In total, we interviewed 407 newborn care providers with a sex ratio of 0.52. Interviewees had over five years work experience in 62.1%. They considered a low Apgar score as an indication for neonatal resuscitation in 89%, regardless of profile (p = 0.1583). They knew the good aspiration technique in 54%, with nurses and midwives more knowledgeable (p < 0.001) of the reference health centers (p = 0.0000). The interviewees knew the indication and rate of ventilation in 30.2% and 16.0%, respectively. About one third (34%) thought oxygen administration should be systematic during ventilation. The knowledge level on ventilation was the lowest in the group of general practitioners (p = 0.0063 for

Abstract: Introduction: Acute post-infectious glomerulonephritis (APIGN) can be serious due to its complications that still occur in our countries. In this work, we aimed to study the epidemiological, clinical, biological and evolutionary aspects of APIGN. Patients and methods: We conducted a retrospective, descriptive study from January 1st, 2015 to December 31st, 2017 in the pediatric ward of the Gabriel Touré Teaching Hospital in Bamako. All children hospitalized for APIGN were included. Results: In two years, we included 10 children aged 7 years old on average; all from low socioeconomic backgrounds. The sex ratio was 1.5. On average, the children spent 15.8 days before our consultation. Edema was the main reason for consultation. We found a history of infection and high blood pressure in 30% each, and renal failure in 10% of the children. Hematuria and proteinuria were detected in 100% and 90%, respectively. Hypocomplementemia was observed in 66.6%. One third of the children had a positive antistreptolysin O. The average duration of hospital stay was 11.2 days. The evolution was favorable in 90%. Kidney failure was the leading cause of death. Conclusion: Acute post-infectious glomerulonephritis is still a reality in our context. Emphasis should be put on its prevention by improving the hygienic conditions, detection and the management of
