[Did child-psychiatry patients really experience the dreaded clinical degradation during the COVID-19 pandemic lockdown?].

Background: The general lockdown period during the COVID-19 pandemic which covered mid-March to mid-May 2020 in France raised important questions about the direct and indirect psychological effects on children and adolescents. Perceived intuitively as harmful and even traumatic in the media's discourse, we tried to better qualify its effects from two complementary approaches. We carried out a review of the literature on the subject to which we associated a regular assessment of the children's global clinical state in the entire active file of the child-psychiatry department of the Centre Hospitalier Universitaire de Brest throughout the lockdown period.

Charge percolation in redox-active thin membrane hybrids of mesoporous silica and poly(viologens).

This work reports the fabrication of redox-active films of oligomeric and molecular viologens and mesoporous silica via the infiltration method. Pore-ellipsometry and UV-vis confirm that low-molecular-weight poly(viologens) in solution are able to enter the mesoporous structure, in contrast to high-molecular weight polymers that adsorb only on top of the film. Cyclic voltammetry shows that viologens are able to reach the bottom of the pores and access the electrode/film interface.

[From the perinatal period to adolescence: the three stages of coordination].

The need for coordinated organisation between infant-child psychiatry and adult psychiatry is highlighted through key periods, with the aid of a clinical case: the perinatal period and the hospitalisation of a mother with her child; the psychiatric support of the unwell mother and that of her daughter; then the transition for the 16-year-old teenager towards adult psychiatry. Taking into consideration the mother-child bond is essential and requires collaborative care projects, the creation of opportunities for joint reflection and organisation, and the acknowledgement that internal institutional divisions exist which are too often denied.

Occupational identity crisis of professionals dealing with difficult adolescents.

This study tests the hypothesis of vulnerability in health and social care professionals dealing with difficult adolescents. This vulnerability appears to be underpinned by an occupational identity crisis that seems to diminish the ability of these professionals to recognize the suffering of these adolescents. A questionnaire was developed and then distributed during a network day bringing together members of various institutions and bodies working with difficult adolescents.

[Partnership around difficult teenagers in Brest].

The issues surrounding difficult teenagers results in professionals formalising a partnership. Certain areas of focus are identified such as getting to know each other better in order to understand each other better, working in a "common language", understanding professional identities, or embracing long term partnership. Pressure to assess and rationalise spending, as well as political challenges, must be taken into consideration.
