Persons with disabilities as experts-by experience: Using personal narratives to affect community attitudes in Kilifi, Kenya

Background: The last decade has seen improved public awareness of disability in sub-Saharan Africa. However, negative and stereotypical views of disability still persist in many communities. We conducted a study to promote awareness of disability in rural Kenya, using a process of reflection and education. This paper reports on the second aspect – education. The research question was: How can personal narratives of living with disability affect community attitudes and responses to disability? Methods: A qualitative phenomenological approach was adopted. Twenty community-based groups involving 249 participants took part. Each group participated in one focus group discussion at baseline, to explore the members’ personal experiences and views of disability. The intervention involved three adults with disabilities sharing their personal narratives with each group. After the intervention, repeat focus group discussions were conducted with each group. Thematic analysis was carried out according to the framework method. Results: The emergent framework consisted of four main themes, organised as opposing constructs: ‘burden’ and ‘agency’, ‘sub-human’ and ‘human’. ‘Burden’ focused on the perceived hopelessness of the situation. Post-intervention revealed greater support for the ‘agency’ of persons with disabilities, evidenced by what the person could do, rather than their inability, and the relevance of support. The ‘sub-human’ to ‘human’ construct captured dehumanising and discriminating practice towards persons with disabilities on one side, and recognition of the person and inclusion in the community on the other. Whilst support and empathy were evident at the pre-intervention stage, post-intervention revealed greater recognition of people with disabilities as fellow human beings. Conclusion: This study provides a proof of concept regarding the deployment of persons with disabilities as agents for change. Exposure to experts-by-experience provided community groups with opportunities to reflect on, examine and adjust their views on disability in this rural part of Kenya. The sharing of personal narratives appeared to resonate with group members, to encourage recognition of the person and not just the disability, and to move their resolve toward ideas for collective action. Further research is needed to assess the effects of such interventions

Touchstone Stars: Highlights from the Cool Stars 18 Splinter Session

We present a summary of the splinter session on "touchstone stars" -- stars with directly measured parameters -- that was organized as part of the Cool Stars 18 conference. We discuss several methods to precisely determine cool star properties such as masses and radii from eclipsing binaries, and radii and effective temperatures from interferometry. We highlight recent results in identifying and measuring parameters for touchstone stars, and ongoing efforts to use touchstone stars to determine parameters for other stars. We conclude by comparing the results of touchstone stars with cool star models, noting some unusual patterns in the differences.Comment: Proceedings of the 18th Cambridge Workshop on Cool Stars, Stellar Systems, and the Sun, Eds G. van Belle & H.

Effect of exercise adjunct to radiation and androgen deprivation therapy on patient-reported treatment toxicity in men with prostate cancer: A secondary analysis of 2 randomized controlled trials

Purpose: Physical inactivity, in addition to clinical factors, has been associated with higher levels of late pelvic symptoms in patients with prostate cancer (PCa) after radiation therapy. The aim of this study was to investigate the effect of a structured multicomponent exercise program comprised of aerobic and resistance training as well as impact loading on the prevalence and severity of symptoms commonly resulting from androgen deprivation therapy (ADT) and pelvic radiation therapy. Methods and Materials: We performed a secondary analysis of pooled data from 2 randomized controlled trials that investigated the role of exercise on treatment-related side effects in patients with PCa receiving ADT. Patients were included in the analysis if they had undergone radiation therapy during the intervention in addition to ADT. Patient-reported quality of life and functional and symptom scales were assessed using the European Organization for Research and Treatment of Cancer QLQ-C30 and PR25 before and after 6 months of exercise or usual care (UC). Results: One-hundred and fifteen patients with PCa receiving ADT, aged 47 to 84 years, who also underwent radiation therapy were included in the analysis (exercise, n = 72; UC, n = 43). There was a significant reduction in physical functioning (P = .019) and increased fatigue (P = .007) in the control group, with no change observed in the exercise group. Similarly, there was a trend toward reduced sexual activity in the control group (P = .064), with a mean adjusted change of -7.1 points. Furthermore, the prevalence of clinically important pain at 6 months was lower in the exercise group compared with UC (18.1 vs 37.2%, P = .022). No between-group differences were found for urinary (P = .473) or hormonal treatment-related symptoms (P = .552). Conclusions: Exercise during concomitant hormone and radiation treatment for men with PCa may mitigate some adverse changes in patient-reported fatigue, physical functioning, and possibly sexual activity. The promotion and provision of exercise to counter a range of treatment-related adverse effects in patients with PCa undergoing radiation therapy and ADT should be actively encouraged

Exercise intervention and sexual function in advanced prostate cancer: A randomised controlled trial

Objectives: Treatments for prostate cancer such as androgen deprivation therapy (ADT), surgery and radiation therapy can adversely affect sexual, urinary and bowel function. Preliminary research has demonstrated the efficacy of exercise to preserve sexual function in men with localised prostate cancer receiving ADT, though this has yet to be investigated in a metastatic setting. We examined the effects of a 12-week exercise programme comprising resistance, aerobic and flexibility training on sexual health and function in men with advanced prostate cancer. Methods: Patients with prostate cancer (70.0±8.4 year; body mass index 28.7±4.0 kg/m2) with bone metastases (rib/thoracic spine, 66.7%; lumbar spine, 43.9%; pelvis, 75.4%; femur, 40.4%; humerus, 24.6%; other sites, 70.2%) were randomly assigned to supervised exercise 3 days/week (n=28) or usual care (n=29). Sexual health and function were assessed using the International Index of Erectile Function, the Expanded Prostate Cancer Index Composite and the EORTC-PR25 at baseline and 12 weeks. Results: Patients attended 89% of planned sessions and there were no adverse events. After adjusting for baseline values, there was no significant difference between groups for any measure of sexual function and activity (p \u3e 0.05). Additionally, there was no significant difference between groups for urinary and bowel function assessed by the EORTC-PR25 (p \u3e 0.05). Conclusions: A short-Term programme of supervised exercise does not appear to enhance indices of sexual health and function in men with advanced prostate cancer. Limitations of the intervention included the conservative modular exercise programme, which deliberately avoided loading bone metastatic sites

Survey of rehabilitation support for children 0-15 years in a rural part of Kenya

Abstract Purpose: Information regarding the nature, availability and distribution of rehabilitation services for children with disabilities across developing countries is scarce, and data that do exist are of variable quality. If planning and development are to progress, information about service provision is vital. The aim was to establish the scope and nature of rehabilitation support available to children with disabilities (0-15 years) and their families in rural Kenya. Method: A comprehensive sample comprising service provision in the health and special education sectors was established. Non-governmental and community-based organisations were also included. A survey of rehabilitation services was conducted through examination of service-related documentation and key informant interviews with the heads of services. Results: Rehabilitation comprised hospital-based occupational therapy, physiotherapy and orthopaedic technology; and seven special education establishments plus an education assessment resource centre. There was one non-government organisation and one community-based organisation relevant to children with disabilities. Activities focused on assessment, diagnosis and raising community awareness. Provision was challenged by inadequate staffing, resources and transport. Government funding was supplemented variously by donations and self-sufficiency initiatives. Rehabilitation approaches appeared to be informed by professional background of practitioner, rather than the needs of child. Service documentation revealed use of inconsistent recording methods. Conclusions: The data highlight the challenges of rehabilitation, demanding greater investment in personnel and their training, more material resources, improved access to the community and better recording mechanisms. Implications for Rehabilitation There needs to be greater investment in rehabilitation provision in developing countries. Consideration of community-based initiatives is required to support better access for all. In order to argue the case for improved resources, better skills and mechanisms for recording, monitoring and evaluating practice are needed

Timing of exercise for muscle strength and physical function in men initiating ADT for prostate cancer

© 2020, The Author(s). Background: Androgen deprivation therapy (ADT) in men with prostate cancer (PCa) results in adverse effects, including reduced muscle strength and physical function, potentially compromising daily functioning. We examined whether it was more efficacious to commence exercise at the onset of ADT rather than later in treatment to counter declines in strength and physical function. Methods: One-hundred-and-four men with PCa (68.3 ± 7.0 years) initiating ADT were randomised to immediate exercise (IMX, n = 54) or delayed exercise (DEL, n = 50) for 12 months. IMX comprised 6 months of supervised resistance/aerobic/impact exercise initiated at the onset of ADT with a 6-month follow-up. DEL comprised 6 months of usual care followed by 6 months of resistance/aerobic/impact exercise. Upper and lower body muscle strength and physical function were assessed at baseline, 6 and 12 months. Results: There was a significant difference for all strength measures at 6 months favouring IMX (P \u3c 0.001), with net differences in leg press, seated row and chest press strength of 19.9 kg (95% CI, 12.3–27.5 kg), 5.6 kg (3.8–7.4 kg) and 4.3 kg (2.7–5.8 kg), respectively. From 7 to 12 months, DEL increased in all strength measures (P \u3c 0.001), with no differences between groups at 12 months. Similarly, physical function improved (P \u3c 0.001) in IMX compared with DEL at 6 months for the 6-m fast walk (−0.2, 95% CI −0.3 to −0.1 s), 400-m walk (−9.7, −14.8 to −4.6 s), stair climb (−0.4, −0.6 to −0.2 s) and chair rise (−1.0, −1.4 to −0.7 s), with no differences between groups by 12 months, except for the 6-m fast walk (P \u3c 0.001). Conclusion: Exercise either at the onset or after 6 months of ADT preserves/enhances muscle strength and physical function. However, to avoid initial treatment-related adverse effects on strength and function, exercise therapy should be implemented with initiation of ADT

Hsp90 Inhibition Suppresses NF-κB Transcriptional Activation via Sirt-2 in Human Lung Microvascular Endothelial Cells

The ability of anti-heat shock protein 90 (Hsp90) drugs to attenuate NF-κB-mediated transcription is the major basis for their anti-inflammatory properties. While the molecular mechanisms underlying this effect are not clear, they appear to be distinct in human endothelial cells. We now show for the first time that type 2 sirtuin (Sirt-2) histone deacetylase binds human NF-κB target gene promoter and prevents the recruitment of NF-κB proteins and subsequent assembly of RNA polymerase II complex in human lung microvascular endothelial cells. Hsp90 inhibitors stabilize the Sirt-2/promoter interaction and impose a “transcriptional block,” which is reversed by either inhibition or downregulation of Sirt-2 protein expression. Furthermore, this process is independent of NF-κB (p65) Lysine 310 deacetylation, suggesting that it is distinct from known Sirt-2-dependent mechanisms. We demonstrate that Sirt-2 is recruited to NF-κB target gene promoter via interaction with core histones. Upon inflammatory challenge, chromatin remodeling and core histone H3 displacement from the promoter region removes Sirt-2 and allows NF-κB/coactivator recruitment essential for RNA Pol II-dependent mRNA induction. This novel mechanism may have important implications in pulmonary inflammation

Time on androgen deprivation therapy and adaptations to exercise: secondary analysis from a 12-month randomized controlled trial in men with prostate cancer

Objectives To explore if duration of previous exposure to androgen deprivation therapy (ADT) in men with prostate cancer (PCa) undertaking a year-long exercise programme moderates the exercise response with regard to body composition and muscle performance, and also to explore the moderator effects of baseline testosterone, time since ADT, and baseline value of the outcome. Patients and Methods In a multicentre randomized controlled trial, 100 men who had previously undergone either 6 months (short-term) or 18 months (long-term) of ADT in combination with radiotherapy, as part of the TROG 03.04 RADAR trial, were randomized to 6 months supervised exercise, followed by a 6-month home-based maintenance programme, or to printed physical activity educational material for 12 months across 13 university-affiliated exercise clinics in Australia and New Zealand. The participants were long-term survivors of PCa with a mean age of 71.7 ± 6.4 years, and were assessed for lower extremity performance (repeated chair rise), with a subset of men (n = 57) undergoing additional measures for upper and lower body muscle strength and body composition (lean mass, fat mass, appendicular skeletal muscle [ASM]) by dual X-ray absorptiometry. Data were analysed using generalized estimating equations. Results Time on ADT significantly moderated the exercise effects on chair rise (βinteraction = −1.3 s, 95% confidence interval [CI] −2.6 to 0.0), whole-body lean mass (βinteraction = 1194 g, 95% CI 234 to 2153) and ASM mass (βinteraction = 562 g, 95% CI 49 to 1075), and approached significance for fat mass (βinteraction = −1107 g, 95% CI −2346 to 132), with greater benefits for men previously on long-term ADT. At 6 months, the intervention effects on chair rise time −1.5 s (95% CI −2.5 to −0.5), whole-body lean mass 824 g (95% CI 8 to 1640), ASM mass 709 g (95% CI 260 to 1158), and fat mass −1377 g (95% CI −2156 to −598) were significant for men previously on long-term ADT, but not for men on short-term ADT. At 12 months, the intervention effects for men on long-term ADT remained significant for the chair rise, with improved performance (−2.0 s, 95% CI −3.0 to −1.0) and increased ASM (537 g, 95% CI 153 to 921). Time on ADT did not moderate the exercise effects on muscle strength, nor did time since ADT cessation moderate any intervention effects. Similarly, testosterone and baseline values of the outcome had negligible moderator effects. Conclusions Men with PCa previously treated long-term with ADT respond more favourably to exercise in terms of lower body muscle performance and body composition (lean and fat mass, and ASM) than those with short-term ADT exposure. As a result, men who were formerly on long-term androgen suppression regimens should be especially prescribed exercise medicine interventions to alleviate residual treatment-related adverse effects
