OBJECTIVES The study compared nasopharyngeal carriage of resistant pneumoniae in human immunodeficiency virus (HIV)-seropositive and -seronegative children. METHODS Nasopharyngeal colonization with Streptococcus pneumoniae was investigated during May 1996 in 162 HIV-negative infants and children (age range, 1-38 mo) and 40 HIV-infected children (age(More)
From 1991 to 1994, a group of Romanian and American colleagues undertook an experimental and humanitarian effort to try to improve the quality of life, mental health, and developmental progress of young children in a Romanian orphanage. In the context of institutional care, we experimentally introduced stable adult-child relationships, small group size, and(More)
INTRODUCTION Adults with end-stage kidney disease (ESKD) treated with haemodialysis experience mortality of between 15% and 20% each year. Effective interventions that improve health outcomes for long-term dialysis patients remain unproven. Novel and testable determinants of health in dialysis are needed. Nutrition and dietary patterns are potential factors(More)
1 We consider a bipartite stochastic block model on vertex sets V1 and V2, with planted partitions in each, and ask at what densities efficient algorithms can recover the partition of the smaller vertex set. When |V2| |V1|, multiple thresholds emerge. We first locate a sharp threshold for detection of the partition, in the sense of the results of Mossel et(More)
UNLABELLED Malnutrition is a major health problem in our country by maintaining a high number of infants with poor nutritional status. Various studies have highlighted the role of infant's malnutrition in the development of adult diseases. METHODS We made a cross-sectional study during six months (October 2010 - March 2011) on a group of 63 infants(More)
In rotor walk on a graph, the exits from each vertex follow a prescribed periodic sequence. We show that any rotor walk on the d-dimensional lattice Z visits at least on the order of t distinct sites in t steps. This result extends to Eulerian graphs with a volume growth condition. In a uniform rotor walk the first exit from each vertex is to a neighbor(More)
Consider “Frozen Random Walk” on Z: n particles start at the origin. At any discrete time, the leftmost and rightmost bn4 c particles are “frozen” and do not move. The rest of the particles in the “bulk” independently jump to the left and right uniformly. The goal of this note is to understand the limit of this process under scaling of mass and time. To(More)
UNLABELLED Prematurity represents an important medical problem due to the increased incidence and complex treatment measures. MATERIAL AND METHOD We have made a cross-sectional study to evaluate the causes and risk factors of prematurity and after-birth evolution in 652 premature children. RESULTS Most children had mothers of low socio-economic status(More)
