Effects of web-based adapted physical activity on hippocampal plasticity, cardiorespiratory fitness, symptoms, and cardiometabolic markers in patients with schizophrenia: a randomized, controlled study.

Among the lifestyle interventions, the physical activity (PA) has emerged as an adjuvant non-pharmacological treatment improving mental and physical health in patients with schizophrenia (SZPs) and increasing the hippocampus (HCP) volume. Previously investigated PA programs have been face-to-face, and not necessary adapted to patients' physiological fitness. We propose an innovative 16-week adapted PA program delivered by real-time videoconferencing (e-APA), allowing SZPs to interact with a coach and to manage their physical condition. The primary goal was to demonstrate a greater increase of total HCP volumes in SZPs receiving e-APA compared to that observed in a controlled group. The secondary objectives were to demonstrate the greater effects of e-APA compared to a controlled group on HCP subfields, cardiorespiratory fitness, clinical symptoms, cognitive functions, and lipidic profile. Thirty-five SZPs were randomized to either e-APA or a controlled group receiving a health education program under the same conditions (e-HE). Variables were assessed at pre- and post-intervention time-points. The dropout rate was 11.4%. Compared to the e-HE group, the e-APA group did not have any effect on the HCP total volumes but increased the left subiculum volume. Also, the e-APA group significantly increased cardiorespiratory fitness (VO2max), improved lipidic profile and negative symptoms but not cognitive functions. This study demonstrated the high feasibility and multiple benefits of a remote e-APA program for SZPs. e-APA may increase brain plasticity and improve health outcomes in SZPs, supporting that PA should be an add-on therapeutic intervention.

[Impact of pelvic floor educational sessions on teenage girls]. / Impact de sessions d'éducation périnéale chez des adolescentes.

INTRODUCTION: Our objective was to evaluate the impact of pelvic floor educational sessions on teenage girls about their general knowledge of pelvic floor disorders (PFD) and the anatomy of the pelvic floor. MATERIAL: Educational sessions were offered to teenage girls from middle and high schools in the city of Caen. Each session included pelvic floor anatomy, urinary and digestive physiology as well as situations that favor PFD. At the beginning and end of the session, the participants received a questionnaire on their knowledge and questions concerning their satisfaction were asked at the end of the session. A questionnaire was sent at 2 months to assess the changes in their urinary and digestive habits as well as the dissemination of information to those around them. RESULTS: One hundred and five teenage girls, average age 15, participated in these sessions; 61% responded at 2 months. The educational sessions have significantly improved knowledge about the pelvic floor. After the sessions, 92% and 52% reported having changed their urinary and defecatory habits. Participants found the sessions very useful and all participants recommended these sessions to a friend. CONCLUSION: Pelvic floor educational sessions improve the knowledge of teenage girls and limit behaviors that favor PFD. Teenage satisfaction is important and the dissemination of information is high. A pelvic floor educational program in schools could help limit risky behaviors for the pelvic floor.

Impact of the national prevention policy and scrum law changes on the incidence of rugby-related catastrophic cervical spine injuries in French Rugby Union.

BACKGROUND AND AIMS: Catastrophic cervical spine injuries are rare in rugby union but require close monitoring. The aim of this study was to analyse the incidence of severe cervical spine injuries and determine the impact of a national prevention programme and new scrum rules implemented by the French Rugby Union. METHODS: A prospective study was performed between 2006 and 2013 including all players affiliated to the French Rugby Union. All cervical spine injuries resulting in death, tetraplegia or a permanent neurological deficit were included. Prevention programmes were implemented from 2007 to 2013 and a change in scrum rules in 2010. To measure the impact of rule changes, results between 2006-2010 and 2010-2013 were compared using a Poisson regression. RESULTS: Altogether, 31 injuries were observed and the mean annual incidence was 1.6 per 100 000 players. There were significantly more injuries in senior players compared to junior players (3.5 vs 0.6 per 100 000 players; CI 95% (2.1 to 4.9) vs (0.1 to 1.0)). Incidence decreased from 1.8 in 2006 to 1.0 per 100 000 players in 2013 (p<0.0001). After 2010, there were significantly fewer injuries during scrums (p=0.02). In contrast, there were significantly more injuries in backs during 2010-2013 compared to 2006-2010 (p=0.003). CONCLUSIONS: The incidence of catastrophic cervical spine injuries has declined in French Rugby Union. The implementation of specific prevention programmes and scrum law changes has notably resulted in a decrease in scrum injuries in forwards. This prospective study should be continued to monitor the future progression of injuries and adapt prevention programmes accordingly.
