Health professionals’ and patients’ perspectives on pelvic floor muscle training adherence : 2011 ICS State-of-the-Science Seminar research paper IV of IV

Aims There is scant information on pelvic floor muscle training (PFMT) adherence barriers and facilitators. A web-based survey was conducted (1) to investigate whether responses from health professionals and the public broadly reflected findings in the literature, (2) if responses differed between the two groups, and (3) to identify new research directions. Methods Health professional and public surveys were posted on the ICS website. PFMT adherence barriers and facilitators were divided into four categories: physical/condition, patient, therapy, and social-economic. Responses were analyzed using descriptive statistics from quantitative data and thematic data analysis for qualitative data. Results Five hundred and fifteen health professionals and 51 public respondents participated. Both cohorts felt “patient-related factors” constituted the most important adherence barrier, but differed in their rankings of short- and long-term barriers. Health professionals rated “patient-related” and the public “therapy-related” factors as the most important adherence facilitator. Both ranked “perception of PFMT benefit” as the most important long-term facilitator. Contrary to published findings, symptom severity was not ranked highly. Neither cohort felt the barriers nor facilitators differed according to PFM condition (urinary/faecal incontinence, pelvic organ prolapse, pelvic pain); however, a large number of health professionals felt differences existed across age, gender, and ethnicity. Half of respondents in both cohorts felt research barriers and facilitators differed from those in clinical practice. Conclusions An emphasis on “patient-related” factors, ahead of “condition-specific” and “therapy-related,” affecting PFMT adherence barriers was evident. Health professionals need to be aware of the importance of long-term patient perception of PFMT benefits and consider enabling strategies.

Identification and characterization of the transcriptional targets of the WNT/β-catenin signaling pathway in granulosa cells

Les Wnts représentent une famille de glycoprotéines de signalisation qui sont connues pour les nombreux rôles qu'ils jouent durant le développement embryonnaire et dans la cancerogénèse. Plusieurs Wnts, leurs récepteurs (Fzd) et d'autres composants des voies de signalisation des Wnt sont exprimés dans l’ovaire postnatal, et il a été démontré que l’expression de certains de ces gènes est régulée pendant le développement et l'ovulation/luteinization folliculaires. Toutefois, leurs rôles physiologiques dans l’ovaire demeurent mal définis. Pour étudier le rôle de WNT4 dans le développement folliculaire, nous avons entrepris d’identifier ses cibles transcriptionnels dans les cellules de la granulosa. Pour ce faire, nous avons employé la souris Catnbflox(ex3)/flox(ex3), chez laquelle une activation constitutive de la voie de Wnt/β-catenin a lieu suite à l’action de la recombinare Cre. Des cellules de la granulosa de ces souris ont été mises en culture et infectées avec un adenovirus pour causer la surexpression de WNT4 ou l’expression de Cre. L’ARN a alors été extrait de ces cellules et analysé par micro-puce. Les résultats ont démontré qu’une forte proportion des gènes induits par WNT4 étaient des gènes impliqués dans la réponse cellulaire au stress. Presque tous gènes induits par WNT4 ont également été induits par Cre, indiquant que WNT4 signale via la voie Wnt/β-catenin dans ces cellules. Nos résultats suggèrent donc que WNT4 favorise la survie des follicules par l’induction de gènes de réponse au stress dans les cellules de la granulosa, augmentant ainsi la résistance cellulaire à l'apoptose.

Scoping review of adherence promotion theories in pelvic floor muscle training : 2011 ics state-of-the-science seminar research paper I of IV

Aims This paper, the first of four emanating from the International Continence Society's 2011 State-of-the-Science Seminar on pelvic-floor-muscle training (PFMT) adherence, aimed to summarize the literature on theoretical models to promote PFMT adherence, as identified in the research, or suggested by the seminar's expert panel, and recommends future directions for clinical practice and research. Methods Existing literature on theories of health behavior were identified through a conventional subject search of electronic databases, reference-list checking, and input from the expert panel. A core eligibility criterion was that the study included a theoretical model to underpin adherence strategies used in an intervention to promote PFM training/exercise. Results A brief critique of 12 theoretical models/theories is provided and, were appropriate, their use in PFMT adherence strategies identified or examples of possible uses in future studies outlined. Conclusion A better theoretical-based understanding of interventions to promote PFMT adherence through changes in health behaviors is required. The results of this scoping review and expert opinions identified several promising models. Future research should explicitly map the theories behind interventions that are thought to improve adherence in various populations (e.g., perinatal women to prevent or lessen urinary incontinence). In addition, identified behavioral theories applied to PFMT require a process whereby their impact can be evaluated.

Pelvic-floor-muscle-training adherence “modifiers” : a review of primary qualitative studies : 2011 ICS State-of-the-Science Seminar research paper III of IV

Aims This review aims to locate and summarize the findings of qualitative studies exploring the experience of and adherence to pelvic floor muscle training (PFMT) to recommend future directions for practice and research. Methods Primary qualitative studies were identified through a conventional subject search of electronic databases, reference-list checking, and expert contact. A core eligibility criterion was the inclusion of verbatim quotes from participants about PFMT experiences. Details of study aims, methods, and participants were extracted and tabulated. Data were inductively grouped into categories describing “modifiers” of adherence (verified by a second author) and systematically displayed with supporting illustrative quotes. Results Thirteen studies (14 study reports) were included; eight recruited only or predominantly women with urinary incontinence, three recruited postnatal women, and two included women with pelvic organ prolapse. The quality of methodological reporting varied. Six “modifiers” of adherence were described: knowledge; physical skill; feelings about PFMT; cognitive analysis, planning, and attention; prioritization; and service provision. Conclusions Individuals' experience substantial difficulties with capability (particularly knowledge and skills), motivation (especially associated with the considerable cognitive demands of PFMT), and opportunity (as external factors generate competing priorities) when adopting and maintaining a PFMT program. Expert consensus was that judicious selection and deliberate application of appropriate behavior change strategies directed to the “modifiers” of adherence identified in the review may improve PFMT outcomes. Future research is needed to explore whether the review findings are congruent with the PFMT experiences of antenatal women, men, and adults with fecal incontinence.
