"Cooperation between physicians and physios fosters trust you know": a qualitative study exploring patients' experience with first-contact physiotherapy for low back pain in French primary care.

BACKGROUND: Physiotherapists working in collaboration with family physicians in French multidisciplinary primary healthcare clinics are now able to manage acute low back pain patients as first-contact practitioners in advanced practice roles. This includes medical act delegation such as making a medical diagnosis and prescribing medication. The aim of this study is to explore patients' experience and perceptions when attending a first-contact physiotherapist (FCP) in an advanced practice collaborative primary care model for acute low back pain (LBP). METHODS: A qualitative study using semi-structured interviews was conducted. Patients that consulted a FCP for acute LBP care in new collaborative model were included. Interviews were transcribed verbatim and inductive thematic analysis was performed to generate themes related to patients' experience and perceptions. RESULTS: Ten patients were interviewed (3 women, 7 men; mean age 36.5 ± 9.63 years). All LBP participants experienced important level of pain and disability. Four overarching themes related to patients' experience with the new FCP model were formalized: 1) "Going to see a physiotherapist who specializes in painful movements, well that makes sense to me", 2) "Physiotherapist offered to give me exercises to do at home to relieve the back pain", 3) "I went there feeling confident", 4) "The physiotherapist can do more than just send you to see more appropriate people". Participants highlighted the need to receive timely and high-quality care and were receptive with being autonomously managed by a FCP. Overall, patients' experiences with FCP model of care were positive. Participants were highly confident in the FCP's ability to perform delegated medical tasks including making a medical diagnosis and prescribing oral medication such as analgesic drugs. Patients felt that a greater expansion of FCPs' scope of practice was needed to improve the model. CONCLUSION: Findings from this study can inform the implementation of FCP in countries where patients are not typically granted FCP by underlining that patients are favourable towards the advance practice model as such models support timely and high-quality care. Further research is needed to better determine the future advance practice physiotherapists' scope of practice in French primary and secondary care settings.

Modulation of astrocyte reactivity improves functional deficits in mouse models of Alzheimer's disease.

Astrocyte reactivity and neuroinflammation are hallmarks of CNS pathological conditions such as Alzheimer's disease. However, the specific role of reactive astrocytes is still debated. This controversy may stem from the fact that most strategies used to modulate astrocyte reactivity and explore its contribution to disease outcomes have only limited specificity. Moreover, reactive astrocytes are now emerging as heterogeneous cells and all types of astrocyte reactivity may not be controlled efficiently by such strategies.Here, we used cell type-specific approaches in vivo and identified the JAK2-STAT3 pathway, as necessary and sufficient for the induction and maintenance of astrocyte reactivity. Modulation of this cascade by viral gene transfer in mouse astrocytes efficiently controlled several morphological and molecular features of reactivity. Inhibition of this pathway in mouse models of Alzheimer's disease improved three key pathological hallmarks by reducing amyloid deposition, improving spatial learning and restoring synaptic deficits.In conclusion, the JAK2-STAT3 cascade operates as a master regulator of astrocyte reactivity in vivo. Its inhibition offers new therapeutic opportunities for Alzheimer's disease.
