Acute and chronic effects of Rhaponticum carthamoides and Rhodiola rosea extracts supplementation coupled to resistance exercise on muscle protein synthesis and mechanical power in rats.

Background: Owing to its strength-building and adaptogenic properties, Rhaponticum carthamoides (Rha) has been commonly used by elite Soviet and Russian athletes. Rhodiola rosea (Rho) is known to reduce physical and mental fatigue and improve endurance performance. However, the association of these two nutritional supplements with resistance exercise performance has never been tested.

The Experience of Psychiatric Care of Adolescents with Anxiety-based School Refusal and of their Parents: A Qualitative Study.

Objective: Anxiety-based school refusal in adolescence is a complex, sometimes difficult to treat disorder that can have serious academic and psychiatric consequences. The objective of this qualitative study was to explore how teens with this problem and their parents experience the psychiatric care received.

Methods: This qualitative multicenter study took place in France, where we conducted semi-structured interviews with adolescents receiving psychiatric care for anxiety-based school refusal and with their parents.

[School refusal: Psychopathological profiles of adolescents followed in a day hospital setting].

Introduction: School refusal appeared when formal education became compulsory in 1882, with the Jules Ferry laws. In international psychiatric classifications, school refusal does not appear as a diagnosis by itself, but it co-exists and is inherent to the symptoms of other psychiatric conditions, in particular of anxiety and depressive disorders. The main goal of this study was to describe psychopathological disorders in teenagers presenting school refusal followed in a day hospital setting.

[The efficacy of care as perceived by adolescents presenting anxiety-based school refusal].

School refusal is a complex disorder which is sometimes difficult to treat and which has potentially significant consequences on the child's schooling and mental health. A qualitative study was carried out in 2014-2015 on the feelings of adolescents and their parents with regard to the efficacy of care. The results show that, while adolescents and parents do not share the same representation of the care objectives, they agree on the therapeutic levers identified as been effective: time and relationships.

[Schizophrenia and cognition: a neurodevelopmental approach].

Accumulating evidence supports the hypothesis of abnormal neurodevelopment in schizophrenia. According to this hypothesis, schizophrenia is the consequence of prenatal abnormalities resulting from the interaction of genetic and environmental factors. In line with this hypothesis, several studies indicate that pregnancy and birth complications are risk factors for developing schizophrenia.
