Developing a core competency and capability framework for advanced practice physiotherapy: A qualitative study

Introduction: There is an urgent need to develop an international competency and capability framework to support standardization of education and roles in advanced practice physiotherapy (APP). This need arose due to the rapid growth of the APP model of care, implemented out of necessity in the absence of agreement as to the competencies and capabilities or formal education required for the roles. This study explores the views and perceptions of practitioners and key stakeholders on a draft competency and capability framework for advanced practice physiotherapists. Objectives: The purpose of this study was to: 1) gather feedback from key stakeholders (advanced practice physiotherapists, researchers, and leaders) on a draft competency and capability framework and 2) use that feedback to revise and improve the draft framework. Design: Qualitative study using a series of four multi-national online focus groups. Thematic analysis was conducted according to Braun and Clarke. Results: Sixteen participants from the United Kingdom, Ireland, Canada, Australia, and New Zealand participated in the study. Five themes were generated after data analysis: clinical expert, experienced communicator, strong leader, collaborator, and knowledge creator). A modified competency and capability framework was developed based on feedback from the focus groups and input from subject matter experts (SMEs). Conclusion: This study provides a modified core competency and capability framework comprising 24 competencies grouped under six domains. This study is a step toward international standardization of advanced practice physiotherapy based on a commonly agreed framework for the education and training of advanced practice physiotherapists

High intraspecific variation of the cell surface physico-chemical and bioadhesion properties in Brettanomyces bruxellensis

Brettanomyces bruxellensis is the most damaging spoilage yeast in the wine industry because of its negative impact on the wine organoleptic qualities. The strain persistence in cellars over several years associated with recurrent wine contamination suggest specific properties to persist and survive in the environment through bioadhesion phenomena. In this work, the physico-chemical surface properties, morphology and ability to adhere to stainless steel were studied both on synthetic medium and on wine. More than 50 strains representative of the genetic diversity of the species were considered. Microscopy techniques made it possible to highlight a high morphological diversity of the cells with the presence of pseudohyphae forms for some genetic groups. Analysis of the physico-chemical properties of the cell surface reveals contrasting behaviors: most of the strains display a negative surface charge and hydrophilic behavior while the Beer 1 genetic group has a hydrophobic behavior. All strains showed bioadhesion abilities on stainless steel after only 3 h with differences in the concentration of bioadhered cells ranging from 2.2 × 102 cell/cm2 to 7.6 × 106 cell/cm2. Finally, our results show high variability of the bioadhesion properties, the first step in the biofilm formation, according to the genetic group with the most marked bioadhesion capacity for the beer group. © 2023 The Author

The F4/AS01B HIV-1 Vaccine Candidate Is Safe and Immunogenic, But Does Not Show Viral Efficacy in Antiretroviral Therapy-Naive, HIV-1-Infected Adults: A Randomized Controlled Trial

The impact of the investigational human immunodeficiency virus type 1 (HIV-1) F4/AS01(B) vaccine on HIV-1 viral load (VL) was evaluated in antiretroviral therapy (ART)-naive HIV-1 infected adults.This phase IIb, observer-blind study (NCT01218113), included ART-naive HIV-1 infected adults aged 18 to 55 years. Participants were randomized to receive 2 (F4/AS01(B)_2 group, N=64) or 3 (F4/AS01(B)_3 group, N=62) doses of F4/AS01(B) or placebo (control group, N=64) at weeks 0, 4, and 28. Efficacy (HIV-1 VL, CD4(+) T-cell count, ART initiation, and HIV-related clinical events), safety, and immunogenicity (antibody and T-cell responses) were evaluated during 48 weeks.At week 48, based on a mixed model, no statistically significant difference in HIV-1 VL change from baseline was demonstrated between F4/AS01(B)_2 and control group (0.073 log(10)copies/mL [97.5% confidence interval (CI): -0.088; 0.235]), or F4/AS01(B)_3 and control group (-0.096 log(10)copies/mL [97.5% CI: -0.257; 0.065]). No differences between groups were observed in HIV-1 VL change, CD4(+) T-cell count, ART initiation, or HIV-related clinical events at intermediate timepoints. Among F4/AS01(B) recipients, the most frequent solicited symptoms were pain at injection site (252/300 doses), fatigue (137/300 doses), myalgia (105/300 doses), and headache (90/300 doses). Twelve serious adverse events were reported in 6 participants; 1 was considered vaccine-related (F4/AS01(B)_2 group: angioedema). F4/AS01(B) induced polyfunctional F4-specific CD4(+) T-cells, but had no significant impact on F4-specific CD8(+) T-cell and anti-F4 antibody levels.F4/AS01(B) had a clinically acceptable safety profile, induced F4-specific CD4(+) T-cell responses, but did not reduce HIV-1 VL, impact CD4(+) T-cells count, delay ART initiation, or prevent HIV-1 related clinical events

Brettanomyces bruxellensis is the main spoilage microbial agent in red wines. The use of fungal chitosan has been authorized since 2009 as a curative treatment to eliminate this yeast in conventional wines and in 2018 in organic wines. As this species is known to exhibit great genetic and phenotypic diversity, we examined whether all the strains responded the same way to chitosan treatment. A collection of 53 strains of was used. In the conditions of the reference test, all were at least temporarily affected by the addition of chitosan to wine, with significant decrease of cultivable population. Some (41%) were very sensitive and no cultivable yeast was detected in wine or lees after 3 days of treatment, while others (13%) were tolerant and, after a slight drop in cultivability, resumed growth between 3 and 10 days and remained able to produce spoilage compounds. There were also many strains with intermediate behavior. The strain behavior was only partially linked to the strain genetic group. This behavior was little modulated by the physiological state of the strain or the dose of chitosan used (within the limits of the authorized doses). On the other hand, for a given strain, the sensitivity to chitosan treatment was modulated by the chitosan used and by the properties of the wine in which the treatment was carried out.Recherches sur l’origine et les effets secondaires des propriétés stabilisantes du chitosane fongique dans le vi

Cross-cutting principles for planetary health education

Since the 2015 launch of the Rockefeller Foundation Lancet Commission on planetary health,1 an enormous groundswell of interest in planetary health education has emerged across many disciplines, institutions, and geographical regions. Advancing these global efforts in planetary health education will equip the next generation of scholars to address crucial questions in this emerging field and support the development of a community of practice. To provide a foundation for the growing interest and efforts in this field, the Planetary Health Alliance has facilitated the first attempt to create a set of principles for planetary health education that intersect education at all levels, across all scales, and in all regions of the world—ie, a set of cross-cutting principles
