Open Journal of Nephrology (OJNeph) , 2017, DOI: 10.4236/ojneph.2017.74012
Abstract: Introduction: Renal disease (RD) in human immunodeficiency virus (HIV) infection is a decisive turning point in the development and prognosis of this disease. In Africa, the prevalence varies between 2.5% and 48.6%. In Senegal, little data are available in the literature. The objective of our study was to describe the epidemiological, clinical, paraclinical, therapeutic and progressional aspects in patients living with HIV (PLWHIV). Patients and methods: This was a retrospective, descriptive and analytical study carried out over a 10-year period in the Department of Internal Medicine and Nephrology at the Aristide Le Dantec Hospital in Dakar, Senegal. We included all 15-year old and above PLHIV with available CD4 count and viral load. Results: Out of 248 PLHIV, 32 had kidney disease (KD), which means a hospital prevalence of 12.9%. The mean age was 51.22 ± 10 years (extremes of 36 and 77 years) with a sex ratio (male/female) of 1.28. Renal signs were dominated by glomerular nephropathy syndrome. It was present at 80%. Tubulo-interstitial nephropathy syndrome and chronic uremic syndrome accounted for 6.25% and 3.1% of cases, respectively. Renal function Impairment was present in 21 patients with 18 cases of acute kidney injury (85.7%) and 3 cases of chronic renal failure (14.3%), including 2 in stage 5 of chronic kidney disease. Renal biopsy (RB) was indicated and performed in 20 (62.5%) patients with glomerular signs in 12 patients (60%). Glomerular lesions were dominated by focal and segmental glomerulosclerosis (FSGS) in 6 cases, membraneous nephropathy (MN) in 4 cases and minimal change disease (MCD) in 2 cases. Tubulo-interstitial and vascular lesions were present in 45% and 12.5% of cases, respectively. In highly active antiretroviral therapy (HAART), 12 (37.5%) patients had total remission, 9 (28.12%) had partial remission. One (3.12%) death from severe metabolic acidosis on chronic renal failure was deplored. Conclusion: This study illustrates the high prevalence of RD in PLHIV in our exercise context.

Abstract: Introduction: Kidney injury is common in the course of lupus and affects the functional and vital prognosis. The risk of progression to end-stage renal failure can reach 40% to 60%. Thus we carried out this work for the purpose of an evaluation of the renal and vital prognosis and to deduce the factors of poor prognosis. Patients and method: This was a retrospective, descriptive and analytical study conducted over a period of 10 years from January 1, 2007 to December 31, 2016, performed in the Nephrology Department of Aristide Le Dantec Hospital in Dakar. Patients with lupus nephritis were included. The studied parameters were epidemiological, clinical, paraclinical and progression. We had done a crossover of the patients to look for the factors of poor renal and vital prognosis. Results: Out of 93 cases of lupus patients, 64 were included, a prevalence of 69%. The mean age of the patients was 31.97 ± 10.44 years old. There were 81% women and 19% men, a sex ratio of 0.23. Class III was found in 24 cases (37.5%), Class IV in 20 cases (31.25%), Class V in 15 cases (23.4%), Class II in 4 cases (6.25%) and Class I in 1 case (1.6%). The combination of corticosteroids and immunosuppressants was used in 56.25% of cases. After a follow-up of six months, 19 patients were in complete remission, 21 had resistance and 9 had partial remission. Of the 21 patients who had resistance, 8 were in chronic renal failure. Death was observed in 5 patients and the causes were in 3 patients: pulmonary embolism, bacterial meningitis and pulmonary tuberculosis. The cause of death was unknown in 2 patients. The factors of poor renal prognosis were lymphopenia, the presence of anti-native DNA antibodies, nephrotic syndrome, microscopic hematuria, tubular atrophy and interstitial fibrosis. Risk factors affecting renal survival were the presence of native anti-DNA antibodies, microscopic hematuria, leukocyturia and the presence of a proliferative class. The factors of poor prognosis were renal failure, lymphopenia, nephrotic syndrome, glomerular sclerosis, arteriosclerosis, interstitial infiltration and tubular atrophy. Conclusion: The risk conferred by nephropathy is greater for proliferative glomerulonephritis; it is also correlated with the presence of persistent nephrotic syndrome or severe renal failure.

Abstract: Multiple myeloma is on the list of neoplasia that may be associated with human immunodeficiency virus infection. It is an affection that aggravates the prognosis in these particular patients. We present the case of a patient with multiple myeloma and HIV infection, revealed by renal failure. This was a 59-year-old patient who was received to the Department of nephrology for renal failure associated with severe aregenerative pancytopenia. In etiological investigations, multiple myeloma associated with HIV1 infection was found. The evolution was unfavorable, marked by the death of the patient caused by digestive haemorrhage before the start of antiretroviral treatment and chemotherapy.

Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.22040
Abstract: We provide an analytical solution for the continuum multi-country two-sector Ricardian model of Yanagawa (1996) [1], and obtain additional results that are not observed in the standard two-country two-good Ricardian model. Increases in productivity in each sector results in an increase in the number of countries producing high technology goods and a de- crease in the number of countries producing low technology goods.

Open Journal of Preventive Medicine (OJPM) , 2014, DOI: 10.4236/ojpm.2014.47064

Objectives: To lay stress upon the importance of adequate water and sanitation in the prevention of cholera in Guinea. Methods: The data on deaths and cases of cholera in Guinea from 2000 to 2011 were downloaded from the WHO Official website. The data on deaths and cases of cholera outbreak which occurred in Guinea from 02 February to 15 October 2012 were collected from the Guinean Ministry of Public Health. The cholera index case is confirmed by a laboratory test. Cholera cases were defined as individuals over one year old who had had watery stools with or without vomiting. Cholera incidence and case fatality rates between different areas of cholera occurrence in the country over time were computed. Results: Over the overall 12-year period (2000-2012), the case fatality rate showed a somewhat sign of slight rising trend when the incidence rates increased rapidly. During the seven consecutive years of cholera outbreaks in Guinea, between 2003 and 2009, the most affected areas were Conakry, Dubreka, Coyah, Boffa, Forécariah, Guékédou, Dalaba and Télimélé. In 2012, Cholera outbreak resulted in an incidence rate of 23.23 per 10,000 population and a case fatality ratio (CFR) of approximately 1.8%. Cases and deaths were reported in 12 prefectures out of 34: Conakry, Coyah, Forecariah, Fria, Boffa, Dubréka, Boké, Mamou, Kindia, Kankan, Kerouané and Dabola. Conclusion: Cholera is an important health problem in Guinea. Any earnest attempts to improve water and sanitation alongside with promotion of good hygienic practices will likely ward off the threat of cholera in the country.

Assessment of Head Injury Criterion Score of Shock Attenuation Material Employed around Playground Equipment Using Nonlinear Spring Contact Model  [PDF]
Yuji Ohue, Keita Miyoshi
Open Journal of Safety Science and Technology (OJSST) , 2014, DOI: 10.4236/ojsst.2014.42009
Abstract: In order to investigate the influence factors on HIC (Head Injury Criterion) score of shock attenuation materials employed around playground, impact tests were carried out in accordance with ASTM standard. Four kinds of the commercial shock attenuation materials were employed for the test. The apparatus is composed of the missile made from aluminum alloy with a mass of 4.6 kg and a triaxial accelerometer. The higher the missile was dropped, the more HIC score increased. The HIC score depended on the peak deceleration in collision. From the time-frequency analysis, it was obvious that HIC score depended on the characteristic frequency of the vibration system in collision between the missile and the shock attenuation material. There was sufficient evidence to suggest that the use of a simple vibration system with a nonlinear hardening spring is beneficial to assess HIC score and peak deceleration for the shock attenuation material.

Abstract: Objectives: Causes and risk factors that result in fatal road traffic accident have not been described at the national level in Guinea yet. The goal of this study is to explore the causes and risk factors related to fatal road traffic accident, identified most vulnerable road users, and inform the road traffic prevention policy in Guinea. Methods: We made a retrospective descriptive analysis based on national fatal road traffic accident data from the Department of Health Information at the Guinean Ministry of Health for year 2011. Results: In 2011, road traffic accident was responsible for an aggregate number of 1655 deaths with an overall death rate of 15.3 per 100,000 population. Male experienced more than twice the risk of death from road traffic accidents (21.9 deaths per 100,000 population) compared with female (9.0 deaths per 100,000 population). While taking the population as a whole, the highest death rate was found among the middle aged in 35 - 49 age group accounting for (29.7 deaths per 100,000 population), followed successively by young adults age group 25 - 34 years (24.6 deaths per 100,000 population), and the middle aged in 50 - 64 age group (22.9 deaths per 100,000 population). Principally, occupants, motorcyclists and pedestrians sustained considerable burden of deaths respectively (9.2; 2.9; 2.2 per 100,000 population). In re-gional setting, the highest death rate was found in Upper Guinea (19.5 per 100,000 population), followed by Forest Guinea (18.7 per 100,000 population) and Middle Guinea (16.8 per 100,000 population). A large proportion of male was killed as motorcyclist than female while high per-centage of female died as occupant than male for all age group. The regional distribution showed that when a remarkable number of occupant death were observed in Upper and Forest Guinea, more people died as pedestrian and pedal cyclist in Conakry. Conclusions: This study demonstrated that most of the deaths were among occupants, motorcyclists and pedestrians, and the productive workforce aged 25 - 49 years. It was found that majority of the deaths happened in Upper Guinea followed by Forest Guinea. Improvement of roads design, strict enforcement of road safety laws and raising the awareness of general public about the causes and risks factors of road traffic accident through various channels are highly required which will promote economic growth in the local communities and then help people escape the poverty trap.
Horton Revisited: African Traditional Thought and Western Science
L Keita
Africa Development , 2007,
Abstract: Over the years Robin Horton has argued for what he refers to as the ‘continuity thesis’ according to which there are theoretical similarities between African traditional thought and modern Western science. Horton’s thesis stands in contrast to the standard Western anthropological appraisal of traditional African thought. The standard appraisal (Levy-Bruhl, Durkheim, Evans-Pritchard, et al.) stated that the two modes of thought were incommensurate. I argue that while the continuity thesis holds for certain aspects of African thought – empirical, protoscientific and metaphysical – it does not apply to traditional African religious expression. My thesis here is that belief systems founded on magic, religion and their combinations should be understood as belonging to what might be referred to as general metaphysics. I argue too that if the continuity thesis is to apply to the history of thought in Africa then the more apt comparison should be between the different phases of technological and scientific thought of the West. Thus Horton’s claim that traditional African religious thought is configured according to the goals of explanation, prediction and control thereby putting it on the same epistemic plane as modern Western science is thereby rendered irrelevant. On the other hand the goal of traditional African religion like that of many other religious traditions – including those of the West – has principally been to seek a conscious communion with ancestors and anthropomorphised godheads and spiritual entities of the metaphysical realm.

Dynamic Structural Modeling and Its Applications: An Analysis of Anxiety Structure
Keita Kinjo
International Journal of Computer Science Issues , 2012,
Abstract: This study aims at investigating and analyzing the changes of consciousness structure. The method is already known and is referred to as structural modeling; to investigate and analyze the change of consciousness structure. However, there have been only a few studies conducted to analyze the change of consciousness structure. We have therefore proposed the dynamic structural modeling as an outline to investigate and analyze the change of consciousness structure. As an example, we have applied the principle to the data about the structural change of human anxiety at the 2011 off the Pacific coast of Tohoku Earthquake and the result gives us useful information.
