[Practices of general practitioners in the follow-up of precarious pregnant patients: A qualitative study].

Objective: Socio-economic conditions are one of the critical factors of the health of pregnant women. However, precariousness remains poorly defined and detected by general practitioners because too few tools adapted to private practice are available. General practitioners, as the first point of contact for these patients and often the future doctors of the children to come, take charge of them or refer them to other practitioners.

Biologics in congenital ichthyosis: are they effective?

Background: Congenital ichthyoses (CI) comprise a heterogeneous group of genetic diseases requiring lifelong treatment and having a major effect on quality of life. Conventional treatments reduce scaling and skin discomfort; however, they usually have little or no effect on erythema and pruritus. The identification of cytokine alterations in CI raised the possibility of repurposing available biologics.

An engineered PET depolymerase to break down and recycle plastic bottles.

Present estimates suggest that of the 359 million tons of plastics produced annually worldwide, 150-200 million tons accumulate in landfill or in the natural environment. Poly(ethylene terephthalate) (PET) is the most abundant polyester plastic, with almost 70 million tons manufactured annually worldwide for use in textiles and packaging. The main recycling process for PET, via thermomechanical means, results in a loss of mechanical properties.
