Socio-spatial inequalities in presence of primary care physicians and patients' ability to register: A simulated-patient survey in the Paris Region.

Objectives: We studied the socio-spatial inequalities of three types of general practitioner (GP) density in the Paris metropolitan area: the density of GPs present (that is, practising) in the census block and of those registering new patients for office visits and, separately, for house calls.

Study Design: An exhaustive simulated patient survey enabled us to determine the number of GPs practising in the Paris metropolitan region accepting new patient registration for continuing care at their office and/or for house calls.

Methods: We measured at the level of a census block three types of GP densities: density of GPs present, density of GPs registering new patients at their office and density of GP registering new patients for house calls.

Age-related changes in how 5- to 8-year-old children use and execute finger-based strategies in arithmetic.

To determine how young children use and execute finger-based strategies, 5- to 8-year-olds were asked to solve simple addition problems under a choice condition (i.e., they could choose finger-based or non-finger strategies on each problem) and under two no-choice conditions (one in which they needed to use finger-based strategies on all problems and one in which they could not use finger-based strategies).

Executive functioning in adolescents and adults with Silver-Russell syndrome.

Silver-Russell syndrome (SRS) is a rare imprinting disorder characterized by prenatal and postnatal growth retardation. The two principal causes of SRS are loss of methylation on chromosome 11p15 (11p15 LOM) and maternal uniparental disomy of chromosome 7 (UPD(7)mat). Knowledge of the neuropsychological profile of SRS remains sparse and incomplete even if several difficulties related to attention and learning have been reported both in the literature and by patients with SRS.

Can quarantine plant-parasitic nematodes within wastes be managed by useful tools in a circular economy approach?

Seen as an integral part of sustainable development, circular economy represents a model of production and consumption notably based on the limitation of both resource wastage and environmental impact. Laboratories and commercial companies working on plant pathogens, in particular quarantine species, must effectively disinfect their waste to avoid disseminating these organisms. The methods used for waste disinfection can however incur high energy costs or pose environmental and human health hazards.
