Background: The global burden of non-communicable diseases is increasing and the need for prevention is huge. Policies have yet to produce results and prevention indicators remain low. Primary care (PC) represents an opportunity to optimise the practice of prevention, but GPs are coming up against barriers that are holding back their prevention practices. Aim: To identify the barriers and facilitators for the implementation of routine prevention practices in PC. Design & setting: This study is an international overview of reviews focusing on the integration of prevention in PC settings. Method: The search was conducted in July 2022 using MEDLINE, Embase, Web of Science, and the Cochrane Database of Systematic Reviews. Included reviews are systematic reviews or scoping reviews adopting a systematic approach. Results: The 35 reviews included identify multiple barriers and facilitators related to the integration of prevention in PC. These factors are heterogeneous with regard to their source (the patient, the professional, and the health system) and their level of action (individual, organisational, or contextual). The results show the need to organise PC at the professional level (for example, in training), at the local level (for example, the information system), and at the political level (for example, the unclear definition of the role of professionals). Conclusion: The factors influencing the integration of prevention in PC are multiple and act at different levels (individual, organisational, and health-system level). Organisation factors play a major role and seem to be a means of overcoming the difficulties encountered by healthcare professionals in developing preventive practices. [ABSTRACT FROM AUTHOR]

Introduction Parkinson's disease (PD), characterized by both motor and nonmotor system pathology, is a common neurodegenerative disorder affecting about 1% of the population over age 60. Its prevalence presents an [...], Parkinson's disease (PD) is a neurodegenerativa disorder associated with loss of striatal dopamine, secondary to degeneration of midbrain dopamine (mDA) neurons in the substantia nigra, rendering cell transplantation a promising therapeutic strategy. To establish human induced pluripotent stem cell-based (hiPSC-based) autologous cell therapy, we report a platform of core techniques for the production of mDA progenitors as a safe and effective therapeutic product. First, by combining metabolism-regulating microRNAs with reprogramming factors, we developed a method to more efficiently generate clinical-grade iPSCs, as evidenced by genomic integrity and unbiased pluripotent potential. Second, we established a 'spotting'-based in vitro differentiation methodology to generate functional and healthy mDA cells in a scalable manner. Third, we developed a chemical method that safely eliminates undifferentiated cells from the final product. Dopaminergic cells thus express high levels of characteristic mDA markers, produce and secrete dopamine, and exhibit electrophysiological features typical of mDA cells. Transplantation of these cells into rodent models of PD robustly restores motor function and reinnervates host brain, while showing no evidence of tumor formation or redistribution of the implanted cells. We propose that this platform is suitable for the successful implementation of human personalized autologous cell therapy for PD.

Introduction: The mental health of residents is a growing significant concern, particularly with respect to hospital and university training conditions. Our goal was to assess the professional, academic, and psychological determinants of the mental health status of all residents of the academy of Lyon, France. Materials and methods: The Health Barometer of Lyon Subdivision Residents (BASIL) is an initiative which consists in proposing a recurrent online survey to all residents in medicine, pharmacy, and dentistry, belonging to the Lyon subdivision. The first of these surveys was conducted from May to July 2022. Participants should complete a series of validated questionnaires, including the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS), and the Kessler Psychological Distress Scale (K6), respectively, and ad-hoc questions assessing their global health and hospital and academic working conditions. A Directed Acyclic Graph (DAG) analysis was conducted prior to multivariable analyses, to explore the determinants associated with low wellbeing (WEMWBS <43) and high psychological distress (K6 ≥ 13). Results: A total of 904 residents (response rate: 46.7%) participated in the survey. A low level of wellbeing was observed in 23% of participants, and was significantly associated to job strain (OR = 2.18; 95%CI = [1.32-3.60]), low social support (OR = 3.13; 95%CI = [2.05-4.78]) and the experience of very poor university teaching (OR = 2.51; 95%CI = [1.29-4.91]). A high level of psychological distress was identified for 13% of participants, and associated with low social support (OR = 2.41; 95%CI = [1.48-3.93]) and the experience of very poor university teaching (OR = 2.89, 95%CI = [1.16-7.21]). Conclusion: Hospital working conditions, social support, and the perception of teaching quality, were three major determinants of wellbeing and psychological distress among health profession residents. Demographic determinants, personal life and lifestyle habits were also associated. This supports a multilevel action in prevention programs aiming to enhance wellbeing and reduce mental distress in this specific population and local organizational specificities.

The specific loss of midbrain dopamine neurons (mDANs) causes major motor dysfunction in Parkinson’s disease, which makes cell replacement a promising therapeutic approach1–4. However, poor survival of grafted mDANs remains an obstacle to successful clinical outcomes5–8. Here we show that the surgical procedure itself (referred to here as ‘needle trauma’) triggers a profound host response that is characterized by acute neuroinflammation, robust infiltration of peripheral immune cells and brain cell death. When midbrain dopamine (mDA) cells derived from human induced pluripotent stem (iPS) cells were transplanted into the rodent striatum, less than 10% of implanted tyrosine hydroxylase (TH)+ mDANs survived at two weeks after transplantation. By contrast, TH− grafted cells mostly survived. Notably, transplantation of autologous regulatory T (Treg) cells greatly modified the response to needle trauma, suppressing acute neuroinflammation and immune cell infiltration. Furthermore, intra-striatal co-transplantation of Treg cells and human-iPS-cell-derived mDA cells significantly protected grafted mDANs from needle-trauma-associated death and improved therapeutic outcomes in rodent models of Parkinson’s disease with 6-hydroxydopamine lesions. Co-transplantation with Treg cells also suppressed the undesirable proliferation of TH− grafted cells, resulting in more compact grafts with a higher proportion and higher absolute numbers of TH+ neurons. Together, these data emphasize the importance of the initial inflammatory response to surgical injury in the differential survival of cellular components of the graft, and suggest that co-transplanting autologous Treg cells effectively reduces the needle-trauma-induced death of mDANs, providing a potential strategy to achieve better clinical outcomes for cell therapy in Parkinson’s disease.In mouse and rat models of Parkinson’s disease, co-transplanting regulatory T cells (Treg cells) improves the survival of grafted midbrain dopamine neurons in cell therapies by reducing the inflammatory response caused by surgical injury.

Summary: Despite the recent surge of research on leader humility, it remains unclear how and when teams benefit from it. Drawing on social cognitive theory, we propose a moderated mediation model that we test using multisource, time‐lagged data collected from 71 teams in a university‐affiliated hospital. We find that humble leaders indirectly enhance team innovation via greater team reflexivity. Additionally, we consider the average level of proactive personality of team members as a boundary condition of the positive effect of leader humility. Our results show that leader humility prompts team reflexivity only when team mean level of proactive personality is high, which in turn increases team innovation. Bridging social cognitive theory with research on humble leadership in teams, our study offers important implications for both theory and practice. [ABSTRACT FROM AUTHOR]
