This paper considers the cycle covering of complete graphs motivated by the design of survivable WDM networks, where the requests are routed on sub-networks which are protected independently from each other. The problem can be stated as follows : for a given graph G, find a cycle covering of the edge set of Kn, where V (Kn) = V (G), such that each cycle in the covering satisfies the disjoint ro...

The last confirmed wild poliovirus (WPV) case in Democratic Republic of the Congo (DRC) had paralysis onset in December 2011 (1). DRC has had cases of vaccine-derived polioviruses (VDPVs) documented since 2004 (Table 1) (1-6). After an outbreak of 30 circulating VDPV type 2 (cVDPV2) cases during 2011-2012, only five VDPV2 cases were reported during 2013-2016 (Table 1) (1-6). VDPVs can emerge fr...

INTRODUCTION Countries in the West and Central African regions struggle to offer quality HIV care at scale, despite HIV prevalence being relatively low. In these challenging operating environments, basic health care needs are multiple, systems are highly fragile and conflict disrupts health care. Médecins Sans Frontières (MSF) has been working to integrate HIV care in basic health services in s...

OBJECTIVES To quantify the potential impact of mass rape on HIV incidence in seven conflict-afflicted countries (CACs), with severe HIV epidemics, in sub-Saharan Africa. DESIGN Uncertainty analysis of a risk equation model. METHODS A mathematical model was used to evaluate the potential impact of mass rape on increasing HIV incidence in women and girls in Burundi, Democratic Republic of Con...

Background Efficient viral load testing is needed for hepatitis C (HCV) surveillance and diagnosis. HCV viral load testing using dried blood spots (DBSs), made with a single drop of finger-prick whole blood on filter paper, is a promising alternative to traditional serum- or plasma-based approaches. Methods We adapted the Abbott Molecular m2000 instrument for high-throughput HCV viremia testi...

BACKGROUND The seventh reported outbreak of Ebola virus disease (EVD) in the equatorial African country of the Democratic Republic of Congo (DRC) began on July 26, 2014, as another large EVD epidemic continued to spread in West Africa. Simultaneous reports of EVD in equatorial and West Africa raised the question of whether the two outbreaks were linked. METHODS We obtained data from patients ...

BACKGROUND Patient charges and availability of dental services influence utilization of dental services. There is little available information on the cost of dental services and availability of materials and equipment in public dental facilities in Africa. This study aimed to determine the relative cost and availability of dental services, materials and equipment in public oral care facilities ...

Title: Modelling strategic interventions in a population with a total fertility rate of 8.3: a cross-sectional study of Idjwi Island, DRC

A doença renal crônica (DRC) refere-se à forma mais conhecida da em pequenos animais, considerada uma causa comum de morbidade e mortalidade. Atualmente são utilizados na rotina clínica veterinária como método diagnóstico a urinálise creatinina sérica, entretanto, ambas consideradas tardias, tendo vista que irão apresentar consideráveis resultados partir 75% comprometimento renal. Em contrapart...
