Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103557
Abstract:
Introduction: Tuberculosis and malnutrition are major health problems in DR Congo, and children are particularly vulnerable. The objective of this study is to determine the incidence of malnutrition in tuberculous children in DR Congo and to identify the associated factors. Methodology: A cross sectional study was conducted, and concerned 22 Tuberculosis Diagnosis and Treatment Centers (TDTCs). It was carried out over a period from 2013 to 2015 and involved 717 tuberculosis children less than 15 years of age. Nutritional status was assessed on the basis of the values of the Z-score Weight for age (global malnutrition) according to the NCHS curves. Results: Tuberculosis incidence was 8.2%. The prevalence of underweight (<﹣2 z-score) is 20.8%, of which 8.4% is severely malnourished (<﹣3 z-score). An age of less than 60 months is significantly associated with poor nutritional status (OR = 0.3, CI 0.2 - 0.5). TB-HIV co-infection is significantly associated with poor nutritional status (OR = 0.4, CI 0.2 - 0.6). It was noticed that the outcome is favorable (recovery) in patients with good nutritional status (OR = 12, CI 8.0 - 18.9). Conclusion: Underweight is present in Congolese tuberculosis children. An adequate nutritional policy is needed to improve the prognosis of the disease.

Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103710
Abstract:
Introduction: The objective of this study is to determine the incidence of acute bronchiolitis of infants in an urban area of the Democratic Republic of Congo to establish the epidemiological, clinical and nutritional profile of affected infants. Methodology: A cross-sectional descriptive study was conducted in Lubumbashi (DR Congo) at three hospitals over a 2-year period from 2013 to 2014. A total of 321 acute bronchiolitis was collected in infants Less than 24 months. Results: A hospital incidence of 3.8% was found. Bronchiolitis occurred most from December (8.7%) until March (8.7%), and the peak was observed in February, i.e. 24.9% of cases, which corresponds to the great rainy season. The average age of children with was calculated 7.78 ± 6.43 months. The prevalence of underweight was 40.6% (n = 129). There was a significant association between pathology and prematurity (p = 0.00, OR = 111 [20.2 - 614.5]) with associated pathologies (p = 0.02 OR = 8 [0.9-64.5]). Conclusion: The incidence of bronchiolitis has declined in comparison to previous studies in the context of our study setting, but it may be regressed if targeted public health measures are taken.

Abstract:
Introduction: This study aims to compare the benefit of two low low-birth weight newborn management methods, namely the “classic” method using incubators, and the Kangaroo method in a hospital setting; and determine the survival prognosis associated with each of these methods. Methods: We conducted a longitudinal cohort study from 2013 to 2015 at the Jason Sendwe General Hospital in Lubumbashi (DR Congo). A total of 200 cases of low birth weight infants were included, followed by one or the other of the methods evaluated. Results: The average weight at the exit was better under Kangaroo (2191.8 ± 212.1 g versus 2068.6 ± 476.5 g) as well as the average gain in weight per day (52.2 ± 9.5 g versus 31.0 ± 15.1 g). Fewer episodes of hypothermia were noted under Kangaroo, and the duration of stay was shorter (10.2 ± 2.9 days versus 13.0 ± 5.4 days). Logistic regression showed that the Kangaroo method is better for the management of premature infants (p = 0.004, ORa = 4.39 (1.60 - 12.04)). Survival is significantly higher under the Kangaroo method (p < 0.001). The median survival under Kangaroo versus classical method was 16 (EIQ: 15 - 16) and 10 (EIQ: 9 - 10) months, respectively. The incidence of Kangaroo deaths was 0.3 cases per 100 P-J versus 1.9 cases per 100 P-D (P < 0.001) using the conventional method. Conclusion: The Kangaroo method is applicable and offers guarantees of a beneficial management in the newborn with low birth weight.

Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103172
Abstract:
Objective: To determine the prevalence of respiratory symptoms and illustrate the dangerousness of the sands dust in the Artisanal carriers in the city of Lubumbashi, Katanga province, in the Democratic Republic of the Congo (DRC). Method: In total, 120 carriers of sand have been recruited in an exhaustive approach with 120 communal administrative officers of Lubumbashi city as control group. Respiratory symptoms were collected using a respiratory questionnaire. A multi-analysis varied with the test of logistic regression has been privileged to determine the association between the characteristics of the carriers and the respiratory symptoms. Results: The prevalence of respiratory symptoms reported in carriers of sands was greater than that of the control group for the symptoms such as: cough in the morning (52.5% against 6.7%), sputum in the morning (35% against 7.5%), shortness of breath after effort (18.3% against 5%), asthma (26.7% against 5%), chronic bronchitis (12.5% against 4.2%), rhinitis (62.5% against 21.7%), conjunctivitis (58.3% against 17.5%). After adjustment, on factors such as age and education, the profession carrier of sands was strongly associated with the risk of developing respiratory symptoms below: spit in the morning, shortness of breath after effort, asthma, chronic bronchitis with a p < 0.001. The Peak Expiratory Flow Rate (PEFR) has been significantly reduced in the Carriers of sands (438.87 ± 109.02) compared to controls (480.14 ± 70.73) (p < 0.05). Conclusion: The profession carriers of sand as practiced in Lubumbashi, without means of adequate protection, carry a clear risk for respiratory health. It is essential to organize a specialized education in medicine of the work which can train doctors with proven expertise to address the enormous need for qualified personnel in this environment considered at risk of breathing.

Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103233
Abstract:
Objective: To determine the prevalence of respiratory symptoms and make an awareness about the harmful effects of ores dust in the Artisanal miner in the city of Lubumbashi, Katanga province, in the Democratic Republic of the Congo (DRC). Method: In total, 104 artisanal miners have been recruited in an exhaustive manner with 122 administrative officers in the town hall of Lubumbashi, responsible for collecting the taxes in the Stations of the bus as the control group. Respiratory symptoms were collected using a standardized questionnaire. To determine the association between the characteristics of the miners and respiratory symptoms reported, a multi-analysis combined with the test of logistic regression has been privileged. Results: The prevalence of the respiratory symptoms was markedly higher in the artisanal diggers, as compared with the group that controls: wheezing (37.5% vs. 7.4%), shortness breathing after effort (26.9% vs. 3.3%), cough (29.8% vs. 12.3%), asthma (24% vs. 1.6%), rhinitis (20.2% vs. 14.8%), conjunctivitis (16.3% vs. 9.8%), and eczema (34.6% vs. 2.5%). After adjusting for age and education level, digger as occupation was strongly associated with a higher risk of developing respiratory and skin problems (p < 0.05). Conclusion: The study revealed that artisanal miner’s professions, as practiced in Lubumbashi, without any protection against dust, have a negative impact on the respiratory health. It proves to be very important to organize a teaching specialized in Occupational Medicine that can train some physicians with an established expertise having to answer if it is needed to be enormous in qualified staff in this area considered at respiratory risk.
Deterministic and Stochastic Schistosomiasis Models with General Incidence  [PDF]
Stanislas Ouaro, Ali Traoré
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.412229
Abstract:

In this paper, deterministic and stochastic models for schistosomiasis involving four sub-populations are developed. Conditions are given under which system exhibits thresholds behavior. The disease-free equilibrium is globally asymptotically stable if R0 < 1 and the unique endemic equilibrium is globally asymptotically stable when R0 > 1. The populations are computationally simulated under various conditions. Comparisons are made between the deterministic and the stochastic model.
