Sylvie Ndongo Amougou, Dieudonné Danwe, Ba Hamadou, Bonaventure Jemea, Ahmadou Musa Jingi
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104247
Abstract:
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 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:

Abstract:
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:
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.

African Journal of Biotechnology , 2007,
Abstract: Two strains of citrus tristeza virus (CTV) were studied for six years in Yaounde in the forest zone of Cameroon. These strains, SNCL2 and SNCL4, were characterized on Lisbon lemon in Nyombe in the littoral zone of Cameroon. They were inoculated onto combinations of Mexican lime/citrange Troyer. The virulent strain SNCL2 induced a lower lateral growth of the trunk of stocks and scions of six years old combinations. These observations were made three years after inoculation. Tristeza symptoms could not allow for differentiation between the two strains of CTV.
Itô Formula for Integral Processes Related to Space-Time Lévy Noise  [PDF]
Raluca M. Balan, Cheikh B. Ndongo
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.610156
Abstract: In this article, we give a new proof of the Itô formula for some integral processes related to the space-time Lévy noise introduced in [1] [2] as an alternative for the Gaussian white noise perturbing an SPDE. We discuss two applications of this result, which are useful in the study of SPDEs driven by a space-time Lévy noise with finite variance: a maximal inequality for the p-th moment of the stochastic integral, and the Itô representation theorem leading to a chaos expansion similar to the Gaussian case.

Product Lines' Feature-Oriented Engineering for Reuse: A Formal Approach
Marcel Fouda Ndjodo,Amougou Ngoumou
International Journal of Computer Science Issues , 2010,
Abstract: The feature oriented method with business component semantics (FORM/BCS) is an extension of the feature oriented reuse method (FORM) developed at Pohan University of Science and Technology in South Korea. It consists of two engineering processes: a horizontal engineering process driven by the FORM domain engineering process and a vertical engineering process driven by the FORM application engineering process. This paper investigates the horizontal engineering process - which consists of analyzing a product line and developing reusable architectures - and shows that this process can be systematized through a set of maps that describe how one can systematically and rigorously derive the fundamental business architectures of a product line from the feature model of that domain. The main result of the paper is therefore that the formalization of the assets of FORM/BCS enables a clear definition of how an activity of the horizontal engineering process produces a target asset from an input one. This result opens the door for the development of a tool supporting the method.
From physical mobility to psychological mobilization: The benefits of changing location and caregiver in a mobile team for adolescent psychiatry  [PDF]

Abstract:

We have developed a mobile team for adolescents with psychological difficulties that can intervene within 48 hours, if necessary. Practically, caregivers working in pairs go wherever the adolescents are (home, General Practioner’s office, etc.), travelling in a motorhome designed as a mobile office. This method allows us to approach more closely the adolescents and their families in the here and now that corresponds to our societal evolution. Most of the adolescents seen by the mobile team do not express any explicit demand but the demand is expressed by the professionals in direct contact with these adolescents in difficulty (school professionals, General Practitioners, etc.), who alert the mobile team and solicit the adolescents’ parents to call the mobile team. One characteristic of this mobile team is the mobility of setting (by changing locations, including the use of a mobile office, and caregivers, so that multiple representations are mobilized). Statistical analyses conducted on 520 adolescents followed by the mobile team showed that the first meetings tend to take place in the family’s home, subsequently transferring to the mobile office and finally in the community mental health centres. There is therefore a transition from the living space (a place that is part of the here and now) to the caregiving space (a space of thought and for thinking), with the mobile office serving as an intermediate step in this movement towards accessing care. Furthermore, there was a significant association between changes of locations and continuity of care. Thus, there were significantly more breakdowns in continuity when the consultations all take place in a single location (family home, mobile office, community centre). The results and their therapeutic implications will be discussed in this article, especially with regard to the key role played by physical movement in psychological mobilization, and by plurality of representations associated with different locations and caregivers.

Abstract: Germination and Seedling Development from Pepper (Capsicum annuum L.) Seeds following Storage in Different Packaging Materials. A study on the germination and seedling development from pepper (Capsicum annuum L.) seeds following storage in different packaging materials was carried out at the Institute of Agricultural Research for Development (IRAD), Njombe Multipurpose Research Station in Cameroon. Germination tests were conducted at 30 days intervals during 24 weeks of seed conservation in the laboratory at ambient temperature. Seeds were prepared from 4 pepper varieties (Safi, Big sun, Thailande and Local) and stored in 5 packaging materials (glass vial, plastic vial, laminated aluminium foil packet, paper and plastic envelope). The experiment was laid out in a 4 x 5 factorial design (4 varieties of pepper x 5 packaging materials) making 20 treatments in 5 replications. At each germination test, germinated seeds were counted everyday during 15 days. To estimate seedling development, 5 seedlings from each pepper variety issued from each packaging material was grown during each germination test in a polythene bag filled with local topsoil. Each sample was repeated 10 times. Thirty days after sowing, observations were made on seedling development parameters. The results obtained show that germination rate is higher immediately after seed preparation for all pepper varieties. Thereafter germination rate declines slowly when seeds are stored in laminated aluminium foil packets and rapidly when they are stored in paper and polythene envelopes. The other packaging materials occupy intermediary positions. Also, seedlings issued from seeds stored in laminated aluminium foil packets are more vigorous than those issued from seeds stored in paper and polythene envelopes during seed conservation period (6 months). The rapid loss of viability in pepper seeds stored in the two last packaging materials could be attributed to their permeability to air and humidity which accelerates seed ageing and deterioration.
