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.

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.
Cycles, the Degree Distance, and the Wiener Index  [PDF]
Daniel Gray, Hua Wang
Open Journal of Discrete Mathematics (OJDM) , 2012, DOI: 10.4236/ojdm.2012.24031
Abstract: The degree distance of a graph G is , where and are the degrees of vertices , and is the distance between them. The Wiener index is defined as . An elegant result (Gutman; Klein, Mihali?,, Plav?i? and Trinajsti?) is known regarding their correlation, that for a tree T with n vertices. In this note, we extend this study for more general graphs that have frequent appearances in the study of these indices. In particular, we develop a formula regarding their correlation, with an error term that is presented with explicit formula as well as sharp bounds for unicyclic graphs and cacti with given parameters.
A Simple Introduction to Gr?bner Basis Methods in String Phenomenology
James Gray
Advances in High Energy Physics , 2011, DOI: 10.1155/2011/217035
Abstract: I give an elementary introduction to the key algorithm used in recent applications of computational algebraic geometry to the subject of string phenomenology. I begin with a simple description of the algorithm itself and then give 3 examples of its use in physics. I describe how it can be used to obtain constraints on flux parameters, how it can simplify the equations describing vacua in 4D string models, and lastly how it can be used to compute the vacuum space of the electroweak sector of the MSSM.
The role of professional networks in radiology services
Southon,Gray;
Revista Panamericana de Salud Pública , 2006, DOI: 10.1590/S1020-49892006000800006
Abstract: recent developments in public health policy have highlighted the central role of the clinical work force in the success of policy implementation, and thus the need for effective human resource policies. given the high level of professionalism in health services, a number of special issues arise, including the organizational structures that best support professional work. experiences from global industries that rely on a highly expert work force show that hierarchical control structures need to be supplemented by a variety of networks. networks are complex structures that are very different from normal hierarchies, and they need to be effectively understood. while they usually develop spontaneously, they are often not optimally structured, adequately supported, or effectively exploited by health service organizations. it is important to understand the nature of networks and how they can be promoted in order to ensure that clinicians are appropriately supported in providing and enhancing services.
Promoting collaboration between health science disciplines at the university of Alberta, Canada
Gray, Genevieve;
Texto & Contexto - Enfermagem , 2005, DOI: 10.1590/S0104-07072005000300006
Abstract: interdisciplinary education, research and practice, improves health care, scholarly productivity, professionals career opportunities and patients/clients and health professionals satisfaction with care and work, respectively. however, it can engender disinterest, suspicion and antagonism if it is not adequately resources. adequate resourcing requires both highly visible commitment from the key leaders in universities and health services and separate, realistic budgets to support initiatives. in addition, and to ensure that the specialist contribution of all health disciplines to human well-being is fostered the practice, research and education of specialist disciplines must also be adequately supported. this is what the health sciences council at the university of alberta since its inception - tried to do. that it has been successful is reflected in its recognition as national leader in interdisciplinarity in health education and research in canada.

Can measuring immunity to HIV during antiretroviral therapy (ART) in children provide a clue to markers of ART effectiveness?
C Gray
Southern African Journal of HIV Medicine , 2005,
Abstract: The vexing issue of whether the immune system can be reconstituted during HIV infection by supplying antiretroviral therapy (ART) has been a question asked about HIV-infected adults and children receiving therapy.1-9 Knowing that the immune system is sufficiently plastic in adults to show restoration of specific and general immunity after receiving ART is promising when translated to paediatric treatment. There is evidence in children of immune reconstitution after receiving various therapeutic regimens.2,10 This review will examine some of the aspects of immune restoration in general, and specifically in children, and pose the question whether knowledge of changes in immunity in tandem with viral suppression can provide clues as to how to measure immune efficacy of ART.
