Evaluating a multicomponent survivorship programme for men with prostate cancer in Australia: A single cohort study

Objective: To evaluate the implementation of a multicomponent survivorship programme for men with prostate cancer and their carers. Design: A single cohort study, guided by the RE-AIM framework. Setting: Multiple health services in Australia. Participants: Men with prostate cancer and their carers, and health professionals. Intervention: A 12-month telehealth programme that provided centralised and coordinated decision and information support, exercise and nutrition management, specialised clinical support and practical support to men and their carers. Data collection: Multiple sources of data including participant-reported health outcomes and experience of care, qualitative interviews, records of the programme were collected at different time points. Results: Reach: Of 394 eligible men at various stages of survivorship, 142 consented (36% consent rate) and 136 (96%) completed the programme. Adoption: All men participated in general care coordination and more than half participated in exercise and/or nutrition management interventions. Participation in the specialised support component (ie, psychosocial and sexual health support, continence management) was low despite the high level of need reported by men. Effectiveness: Overall, the men reported improvements in their experience of care. Implementation: Factors such as addressing service gaps, provision of specialised services, care coordination, adoption of needs-based and telehealth-based approaches were identified as enablers to the successful implementation of the programme. Issues such as insufficient integration with existing services, lack of resources and high caseload of the intervention team, men\u27s reluctance to discuss needs and lack of confidence with technology were barriers in implementing the programme. Conclusion: Survivorship interventions are relevant to men regardless of the stage of their disease and treatments undertaken. It is possible to provide access to a comprehensive model of survivorship care to promote the health and quality of life for men with prostate cancer. Trial registration number: This study was registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12617000174381)

An integrated multicomponent care model for men affected by prostate cancer: A feasibility study of TrueNTH Australia

Objective: To evaluate the feasibility of implementing an integrated multicomponent survivorship care model for men affected by prostate cancer. Methods: Using a single arm prospective cohort study design, men with prostate cancer were recruited from two regional public hospitals in Australia for a 6-months program that provided information and decision support, exercise and nutrition management, specialised clinical support, and practical support through localised and central care coordination. Carers of the men were also invited to the program. Data were collected from multiple sources to evaluate: (1) recruitment capability and participant characteristics; (2) appropriateness and feasibility of delivering the specific intervention components using an electronic care management tool; and (3) suitability of data collection procedures and proposed outcome measures. Results: Of the 105 eligible men, 51 (consent rate 49%) participated in the program. Of the 31 carers nominated by the men, 13 consented (consent rate 42%). All carers and 50 (98%) men completed the program. Most (92%) men were newly diagnosed with localised prostate cancer. All men attended initial screening and assessment for supportive care needs; a total of 838 episodes of contact/consultation were made by the intervention team either in person (9%) or remotely (91%). The intervention was implemented as proposed with no adverse events. The proposed outcome measures and evaluation procedures were found to be appropriate. Conclusions: Our results support the feasibility of implementing this integrated multicomponent care model for men affected by prostate cancer

Omega-3 Fatty Acids Modify Human Cortical Visual Processing—A Double-Blind, Crossover Study

While cardiovascular and mood benefits of dietary omega-3 fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are manifest, direct neurophysiological evidence of their effects on cortical activity is still limited. Hence we chose to examine the effects of two proprietary fish oil products with different EPA∶DHA ratios (EPA-rich, high EPA∶DHA; DHA-rich) on mental processing speed and visual evoked brain activity. We proposed that nonlinear multifocal visual evoked potentials (mfVEP) would be sensitive to any alteration of the neural function induced by omega-3 fatty acid supplementation, because the higher order kernel responses directly measure the degree of recovery of the neural system as a function of time following stimulation. Twenty-two healthy participants aged 18–34, with no known neurological or psychiatric disorder and not currently taking any nutritional supplementation, were recruited. A double-blind, crossover design was utilized, including a 30-day washout period, between two 30-day supplementation periods of the EPA-rich and DHA-rich diets (with order of diet randomized). Psychophysical choice reaction times and multi-focal nonlinear visual evoked potential (VEP) testing were performed at baseline (No Diet), and after each supplementation period. Following the EPA-rich supplementation, for stimulation at high luminance contrast, a significant reduction in the amplitude of the first slice of the second order VEP kernel response, previously related to activation in the magnocellular pathway, was observed. The correlations between the amplitude changes of short latency second and first order components were significantly different for the two supplementations. Significantly faster choice reaction times were observed psychophysically (compared with baseline performance) under the EPA-rich (but not DHA-rich) supplementation, while simple reaction times were not affected. The reduced nonlinearities observed under the EPA-rich diet suggest a mechanism involving more efficient neural recovery of magnocellular-like visual responses following cortical activation

Implementing a specialist prostate cancer nursing service: a multimethod investigation of factors influencing program outcomes

The increasing complexity of cancer treatment has meant that care coordination and provision of specialised information and support have become increasingly important nursing functions. Significant variation exists in how such functions are implemented in practice and there is limited information to guide development and implementation of such nursing models. The aim of this study was to evaluate a new prostate cancer nursing service implemented in 14 metropolitan and rural settings in Australia to improve patient and health service outcomes. The evaluation focused on understanding critical functions of the nursing role and factors influencing implementation of the program. A multimethod approach was used involving interviews and analysis of health service data. In-depth individual interviews were conducted with 11 specialist prostate cancer, 9 service managers, and 31 multidisciplinary team members. Two researchers undertook thematic analyses of verbatim transcripts to reach agreement on key themes. Service data for a total of 12808 patient contacts across the 14 sites was also analysed. Key themes reflected that core functions of the nursing role included care coordination, assessment, management and referral, and provision of specialised support. Strategies used to ensure the nursing service reached men with greatest need or at higher risk of poorer outcomes included identifying, assessing, and prioritising patients with urgent side effects, complex needs, issues or complications, advocating for the man and involving the multidisciplinary team, and proactively responding to identified clinical and social risk factors. A range of system and service related factors influenced the success of the service, including positive relationships with the multidisciplinary team, physical and functional integration of the nurse within the service, the presence of integrated service networks, role clarity and effective clinical governance, adequate facilities and resources to support the role, and long term plans for sustainability. Opportunities for extending the impact of the role included building community and professional engagement and supporting innovative service delivery models. Specialist oncology nurses who have dedicated coordination and supportive care functions play an important role in contemporary health care environments. Optimizing outcomes from such services requires a range of supporting systems, including interdisciplinary collaboration, effective clinical governance, clear service networks and pathways, and adequate professional supports and resources

Omega-3 supplementation improves cognition and modifies brain activation in young adults

Objective The current study aimed to investigate the effects of eicosapentaenoic acid (EPA)-rich and docosahexaenoic acid (DHA)-rich supplementations on cognitive performance and functional brain activation. Design A double-blind, counterbalanced, crossover design, with a 30-day washout period between two supplementation periods (EPA-rich and DHA-rich) was employed. Functional magnetic resonance imaging scans were obtained during performance of Stroop and Spatial Working Memory tasks prior to supplementation and after each 30-day supplementation period. Results Both supplementations resulted in reduced ratio of arachidonic acid to EPA levels. Following the EPA-rich supplementation, there was a reduction in functional activation in the left anterior cingulate cortex and an increase in activation in the right precentral gyrus coupled with a reduction in reaction times on the colour-word Stroop task. By contrast, the DHA-rich supplementation led to a significant increase in functional activation in the right precentral gyrus during the Stroop and Spatial Working Memory tasks, but there was no change in behavioural performance. Conclusions By extending the theory of neural efficiency to the within-subject neurocognitive effects of supplementation, we concluded that following the EPA-rich supplementation, participants' brains worked 'less hard' and achieved a better cognitive performance than prior to supplementation. Conversely, the increase in functional activation and lack of improvement in time or accuracy of cognitive performance following DHA-rich supplementation may indicate that DHA-rich supplementation is less effective than EPA-rich supplementation in enhancing neurocognitive functioning after a 30-day supplementation period in the same group of individuals

The effects of Omega-3 fish oils and multivitamins on cognitive and cardiovascular function: a randomized, controlled clinical trial

The present randomized, placebo-controlled, double-blind, parallel-groups clinical trial examined the effects of fish oil and multivitamin supplementation on the incorporation of n-3 and n-6 fatty acids into red blood cells. Healthy adult humans (n = 160) were randomized to receive 6 g of fish oil, 6 g of fish oil plus a multivitamin, 3 g of fish oil plus a multivitamin or a placebo daily for 16 weeks. Treatment with 6 g of fish oil, with or without a daily multivitamin, led to higher eicosapentaenoic acid (EPA) composition at endpoint. Docosahexaenoic acid (DHA) composition was unchanged following treatment. The long chain LC n-3 PUFA index was only higher, compared to placebo, in the group receiving the combination of 6 g of fish oil and the multivitamin. Analysis by gender revealed that all treatments increased EPA incorporation in females while, in males, EPA was only significantly increased by the 6 g fish oil multivitamin combination. There was considerable individual variability in the red blood cell incorporation of EPA and DHA at endpoint. Gender contributed to a large proportion of this variability with females generally showing higher LC n-3 PUFA composition at endpoint. In conclusion, the incorporation of LC n-3 PUFA into red blood cells was influenced by dosage, the concurrent intake of vitamin/minerals and gender.

Implementation of a Multidisciplinary Model of Care for Women With Metastatic Breast Cancer: Challenges and Lessons Learned

The present study examined the implementation of a multidisciplinary team model of care for 62 women with metastatic breast cancer who had accessed specialist services at a large Australian cancer center. The model of care strengthened team collaboration and assisted in the delivery of personalized assessment and complex care plans. However, new resources were required to deliver consistent care. Introduction: The present study examined the feasibility and effects of integrating a multidisciplinary team (MDT) model of care for women with metastatic breast cancer (MBC) into a large Australian cancer center. The challenges encountered and lessons learned are described. Patients and Methods: In the present prospective, longitudinal, mixed-methods implementation study, the MDT model included face-to-face consultations with a breast care nurse and social worker, followed by a MDT case discussion and face-to-face delivery of a personalized management plan. Data were collected to describe the cohort of women living with MBC who had attended a specialist breast cancer service and their supportive care needs. Results: A total of 62 women with median age of 60 years (interquartile range [IQR], 37-82 years) participated. The median interval from the first breast cancer diagnosis was 5.7 years (IQR, 2.0-11.6 years), and the median interval from the diagnosis of MBC was 2.0 years (IQR, 0.9-3.6 years). The MDT care model required new resources and cross-sector participation. However, the participants indicated a preference for personalized needs assessment and care planning at the diagnosis of MBC. Conclusions: The results highlight the challenges of implementing and evaluating an MDT care model for women with MBC. The model coordinated MDT collaboration to strengthen the delivery of complex care plans. Investment in cross-sector partnerships to optimize care coordination for women with MBC was needed.</p

Fish oil and multivitamin supplementation reduces oxidative stress but not inflammation in healthy older adults: a randomised controlled trial

The effects of daily fish oil supplementation, with and without multivitamins, on biochemical markers of health were examined. Healthy adults (N = 160) were randomised to receive 3 g of salmon oil with a multivitamin, 6 g of salmon oil with a multivitamin, 6 g of salmon oil in isolation or placebo in a double-blind fashion on a daily basis for 16 weeks. Relative to placebo, both 6 g salmon oil groups displayed significantly lower F2-isoprostane levels at endpoint. Increases in red blood cell polyunsaturated fatty acids correlated with reductions in F2-isoprostanes. Treatment had no effect on inflammatory cytokines, C-reactive protein, fibrinogen, cholesterol or triacylglycerol
