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:

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.

Open Journal of Rheumatology and Autoimmune Diseases (OJRA) , 2016, DOI: 10.4236/ojra.2016.61001
Abstract: Introduction: Studies on RA (rheumatoid arthritis) and cardiovascular risk in African countries are scarce. Objective: To investigate the relationship between RA and cardiovascular risk in Cameroonian patients. Methodology: In 50 Black RA patients and 51 matched healthy individuals from the general population, we studied cardiovascular risk factors validated by the WHO. Cardiovascular risks estimates were carried out using WHO risk charts for the African region. Epi-info, R and SPPS were used for the statistical analysis. Results: Overall and abdominal adiposity as expressed by increased body mass index and abdominal obesity, were all markedly increased in RA patients compared to non-RA subjects [70% vs. 47%, OR (95% CI) = 2.62 (1.16 - 5.94), p = 0.026; and 54% vs. 33%, OR (95% CI) = 2.34 (1.05 - 5.25), p = 0.045 respectively]. RA patients were more physically inactive than their non-RA counterparts (20% vs. 0, p = 0.001). Whereas RA was associated with a reduced odds of alcoholism [OR (95% CI) = 0.19 (0.06 - 0.62), p = 0.005]. Increased BMI seemed to occur independently of methotrexate (p = 0.76), hydroxychloroquine (p = 0.59), corticosteroids (p = 0.79) treatments, and independently of sex (p = 0.15), age (p = 0.67), and sedentary lifestyle (p = 0.16) in RA patients; but their BMI was weakly correlated with disease duration (r = 0.26; p = 0.074). Meanwhile, male gender was associated with a reduced odds of abdominal obesity [OR (95% CI) = 0.02 (0 - 0.4), p = 0.011]. Cardiovascular risk, comparable by proportions between RA and non-RA subjects, was low in 26 patients (78.8%) and 30 non-RA subjects (83.3%) respectively. Conclusion: Despite the high adiposity burden and a sedentary lifestyle experienced by RA patients compared to their healthy counterparts, RA was not associated with cardiovascular risk as estimated by WHO risk charts.

Background: The?burden of peripheral artery disease (PAD) is not well known among apparently healthy people in Africa. Aim: To determine the prevalence and associated risk factors of PAD in a group of blood donors seen at the Douala General HospitalCameroon. Methods: Between 1st November 2015 and 30th April 2016, we carried out a cross-sectional study. Participants were consenting adults of both sexes, aged ≥ 21 years who presented for blood donation, and were tested HIV negative. We collected socio-demographic data and their past history. We carried out a physical examination and measured their Ankle-Brachial Index (ABI). We defined PAD as an ABI < 0.9. We also measured their fasting blood glucose and lipid profile. Results: We recruited 103 participants, 55.4% males. The mean age was 33 ± 10 years. The mean ABI on left and right leg was 1.04 ± 0.1 and 1.02 ± 0.1respectively. ABI was higher in males than females both legs (p < 0.05). PAD was seen in 11 (10.7%) participants. This was higher in females than males (3.6% versus 19.2%, p = 0.026). Among those with PAD, 8 (72.7%) were asymptomatic (Males: 100% versus Females: 66%, p

Abstract: Background: Venous thromboembolism (VTE) is a major cause of morbidity and mortality worldwide. It is also the most common complication in hospitalized patients. Aims:?To?study the in-hospital prevalence of VTE, describe the socio-demographic characteristics of patients, determine the frequency of risk factors, describe the clinical presentations, and determine the short term outcome of VTE in hospitalized patients in a low-income tertiary hospital setting.Methods: We carried out a cross-sectional descriptive retrospective study over a period of 6 years and 4 months (January 2008 to April 2014) in the Douala General HospitalCameroon. Patients were cases of confirmed venous thromboembolic disease (VTE).Results: A total of 78 case files were retained for this study, giving an in-hospital prevalence of 4.4 per 1000 admissions. There were 42 (53.8%) males and 36 (46.1%) females. Their ages ranged from 18 to 89 years (median: 53 years, [IQR: 40?-?61]).There were 37 (47.4%) cases of Deep Vein Thrombosis (DVT), 31 (39.7%) cases of Pulmonary Embolism (PE), and 10 (12.8%) cases of PE associated with DVT (12.8%). The main risk factors were obesity (44.9%), hypertension (37.2%), immobility (20.5%), and long-haul travel (17.9%). The most frequent clinical presentations in PE were dyspnea (80.5%) and chest pain (65.9%). There were 8 (10%) in-hospital deaths. Conclusion: About twelve cases of VTE are seen yearly at the DGH, with an in-hospital mortality of ten percent. Obesity and hypertension were the main risk factors, with dyspnea and chest pain being the main clinical manifestations in PE, and lower limb swelling the main symptom in DVT.

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.

Introduction: High blood pressure is a public problem worldwide because of its high morbidity and mortality. The greatest burden is in low-income set-tings. The burden of disease has not been studied in health workers in our setting. Methods: Between December 2016 and June 2017, we carried out a cross-sectional descriptive and analytic study in two teaching hospitals in Yaounde, using the WHO STEP wise approach. Participants were consenting Physicians, Nurses, Midwives, and Nursing assistants of both sex, aged ≥ 21 years. Results: A total of 266 health workers were screened—31 Physicians, 144 Nurses, 80 Nursing assistants, and 11 Midwives. Their mean age was 41.1 ± 7.6 years (25 to 66 years), and 84.6% were females. The prevalence of Hypertension was 13.9%, of which 54.1% were newly diagnosed—Awareness rate of 45.9%. The control rate of known cases of hy-pertension was 64.7% (64.3% in those on monotherapy, and 66.7% in those on bitherapy). Age > 40 years, and adiposity were significantly associated with hypertension. Conclusion: Compared to the general population, the prevalence of hypertension amongst health workers was low, but with a high rate of un-awareness.

Abstract: Background: Venous thromboembolic disease (VTE) is one of the main causes of cardiovascular death and a public health problem worldwide. It is?one of the most complications in admitted patients, particularly inlow-income settings. The epidemiological data on VTE are still lacking. Methods: We carried out a cross-sectional study in three hospitals in Yaoundé. We retrospectively reviewed records of patients admitted for VTE from January 2013 to December 2017. We collected data on socio-demography, clinical presentation, venous Doppler/pulmonary CT scan, and outcome. Results: We included 93 patients (43 males) with VTE. Their mean age was 53.3 ± 16.6 years. There were 46 (49.5%) cases of Deep Vein Thrombosis (DVT), 36 (38.7%) cases of Pulmonary Embolism (PE), and 11 (11.8%) cases of PE associated with DVT. The main risk factors were obesity/overweight (58.1%), immobility (43%), HIV infection (22.6%), prior admission (22.6%), and long trip (19.4%). The most frequent clinical presentation for PE was dyspnea (100%), tachypnea (87.2%), and chest pain (70.2%). For DVT, limb pain (93%), calf stiffness (86%), limb volume > 3 cm (82.4%) were the most common presentation. There were 9 (9.7%) in-hospital deaths. Mean hospital stay was 20.7 ± 30.8 days. Conclusion:VTE is underdiagnosed in our setting. Obesity and immobility were the main risk factors. Dyspnea and tachypnea were the main clinical presentation for PE whereas limb pain and calf stiffness were the main symptoms for DVT. In-hospital mortality is still high.

Abstract: Background Left ventricular hypertrophy (LVH) is a major cardiovascular risk factor. The electrocardiogram (ECG) has been shown to be a poor tool in detecting LVH due to cardiac and extracardiac factors. We studied the determinants and possibility of improving the test performance of the ECG in a group of Black Africans. Methods We studied echocardiograms and electrocardiograms of 182 Cameroonian patients among whom 113 (62.1%) were having an echocardiographic LVH. Echocardiographic LVH was defined as Left Ventricular Mass Indexed to height 2.7(LVMI)>48 g/m2.7 in men, and >44 g/m 2.7 in women or Body Surface Area ≥116 g/m2 in men, and ≥96 g/m2 in women. Test performances were calculated for 6 classic ECG criteria Sokolow-Lyon, Cornell, Cornell product, Gubner-Ungerleiger, amplitudes of R in aVL, V5 and V6. Results The most sensitive criteria were Cornell (37.2%) and Sokolow-Lyon index (26.5%). The most specific criteria were Gubner (98.6%), RaVL (97.1%), RV5/V6 (95.7%) and Cornell product (94.2%). The performance of the ECG in diagnosing LVH significantly increased with the severity of LVH for Cornell index (r = 0.420, p<0.0001) and Sokolow index (r = 0.212, p = 0.002). It decreased with body habitus (r = ?0.248, p = 0.001) for Sokolow-Lyon index. Cornell index was less affected (age p = 0.766; body habitus: p = 0.209). After sex-specific adjustment for BMI, Cornell BMI sensitivity increased from 37.2% to 69% (r = 0.472, p<0.0001), and Sokolow-Lyon BMI sensitivity increased from 26.5% to 58.4% (r = 0.270, p<0.001). Conclusion The test performance of the ECG in diagnosing LVH is low in this Black African population, due to extracardiac factors such as age, sex, body habitus, and cardiac factors such as LVH severity and geometry. However, this performance is improved after adjustment for extracardiac factors.
Finite and infinite time horizon for BSDE with Poisson jumps

Mathematics , 2012,
Abstract: This paper is devoted to solving a real valued backward stochastic differential equation with jumps where the time horizon may be finite or infinite. Under linear growth generator, we prove existence of a minimal solution. Using a comparison theorem we show existence and uniqueness of solution to such equations when the generator is uniformly continuous and satisfies a weakly monotonic condition.
