Beliefs about inevitable decline among home-living older adults at risk of malnutrition: a qualitative study

BACKGROUND

Approximately 14% of free-living adults aged ≥65 years are at risk of malnutrition. Malnutrition screen and treat interventions in primary care are few, show mixed results, and the advice given is not always accepted and followed. We need to better understand the experiences and contexts of older adults when aiming to develop interventions that are engaging, optimally persuasive and relevant.

METHODS

Using the Person-based Approach, we carried out 23 semi-structured interviews with purposively selected adults ≥65 years with chronic health or social conditions associated with malnutrition risk. Thematic analysis informed the development of key principles to guide planned intervention development.

RESULTS

We found that individuals' beliefs about an inevitable decline in appetite and eating in older age compound the many and varied physical and physiological barriers that they experience. Also, we found that expectations of decline in appetite and physical ability may encourage resignation, reduce self-efficacy to overcome barriers, and reduce motivation to address weight loss and/or recognise it as an issue that needs to be addressed. Fear of loss of independence may also reduce the likelihood of asking general practitioners for advice.

CONCLUSIONS

The key findings identified include a sense of resignation, multiple different barriers to eating and a need for independence, each underpinned by the expectation of a decline in older adulthood. Interventions need to address misperceptions about the inevitability of decline, highlight how and why diet recommendations are somewhat different from recommendations for the general population, and suggest easy ways to increase food intake that address common barriers.

Techniques and Outcomes of Salvage Robot-Assisted Radical Prostatectomy (sRARP)

BACKGROUND

Salvage Robot-Assisted Radical Prostatectomy (sRARP) has been described as feasible treatment for the management of localised prostate cancer (PCa) recurrence after primary treatment. However, no large reports have published cancer and quality outcomes.

OBJECTIVE

To report perioperative, functional and oncologic outcomes of sRARP in patients with localised PCa recurrence.

DESIGN, SETTING, AND PARTICIPANTS

We retrospectively evaluated 106 patients with local recurrence eligible for sRARP.

SURGICAL PROCEDURE

Surgery was performed using the DaVinci Si system similar to the standard approach but with adaptation to the primary treatment.

MEASUREMENTS

Peri-operative outcomes included 90-day complication rate. Functional outcomes included rates of incontinence and erectile dysfunction. Oncological outcomes included tumour staging, margin rate and recurrence.

RESULTS AND LIMITATIONS

Primary treatment was High Intensity Focused Ultrasound (HIFU) in 59 (56%) patients, 27 (25%) radiotherapy, 10 (9%) seed brachytherapy, 8 (8%) solitary androgen deprivation therapy (ADT), one (1%) cryotherapy and one (1%) electroporation / Nanoknife. Median follow-up was 2.1 years. 90-day complication rate was 8%. At two years or more, 50% were fully continent and 33% were socially continent. Continence rates tended to be better after focal compared to whole-gland treatments. Erectile dysfunction was present in 95%. Positive surgical margin rate was 39%. Biochemical recurrence occurred in 13% and local or metastatic recurrence in 11%.

CONCLUSIONS

sRARP is technically more challenging but is a feasible option in high-volume centres for treatment of recurrent PCa. Patients should be counselled that functional outcomes are inferior to primary RARP. Adjustment of surgical technique according to the primary treatment is key for good surgical outcomes.

PATIENT SUMMARY

We report our experience with sRARP for the management of localised PCa recurrence after primary treatment. This represents a feasible approach with acceptable peri-operative complications and cancer outcomes. Functional outcomes are inferior to RARP in the primary setting.

TechCare: Mobile-assessment and therapy for psychosis: An intervention for clients within the early intervention service

Introduction

In the UK, mental illness is a major source of disease burden costing in the region of £105 billion pounds. mHealth is a novel and emerging field in psychiatric and psychological care for the treatment of mental health difficulties such as psychosis.

Objective

To develop an intelligent real-time therapy (iRTT) mobile intervention (TechCare) which assesses participant's symptoms in real-time and responds with a personalised self-help based psychological intervention, with the aim of reducing participant's symptoms. The system will utilise intelligence at two levels:

– intelligently increasing the frequency of assessment notifications if low mood/paranoia is detected;

– an intelligent machine learning algorithm which provides interventions in real-time and also provides recommendations on the most popular selected interventions.

Aim

The aim of the current project is to develop a mobile phone intervention for people with psychosis, and to conduct a feasibility study of the TechCare App.

Methods

The study consists of both qualitative and quantitative components. The study will be run across three strands:

– qualitative work;

– test run and intervention refinement;

– feasibility trial.

Results

Preliminary analysis of qualitative data from Strand 2 (test run and intervention refinement) in-depth interviews with service users (n = 2) and focus group with health professionals (n = 1), highlighted main themes around security of the device, multimedia and the acceptability of psychological interventions being delivered via the TechCare App.

Conclusions

Research in this area can be potentially helpful in addressing the demand on mental health services globally, particularly improving access to psychological interventions.

190 Effect of TCM-199 and synthetic oviductal fluid medium supplemented with varying hormone concentrations on invitro maturation of canine oocytes

Invitro oocyte maturation (IVM) in the domestic canine is yet to be optimized, with low rates of cumulus-oocyte complexes (COCs) reaching MII. This limits the progression of assisted reproductive technologies, which could benefit breeding programs for assistance dogs and endangered Canidae. Canine oocyte maturation differs from that in other mammals, with the ovulation of a COC in the germinal vesicle stage and nuclear maturation occurring in the oviduct. Because of this, the environment in which a canine COC matures is unlike that of other mammals, meaning that IVM protocols cannot be readily adapted. The aim of the current work was to determine (1) the effects of varying concentrations of FSH, human chorionic gonadotrophin (hCG), and oestradiol (E2) during IVM on meiotic resumption and nuclear maturation of canine COCs; and (2) the optimal medium base, either synthetic oviductal fluid (SOF) or tissue culture medium-199 (TCM). Reproductive tracts of bitches (6 months to 7 years of age) were collected from veterinary clinics within 2h of routine spaying. Ovaries were sliced using a scalpel blade, releasing the COCs into aspiration medium. The COCs were randomly allocated to a maturation medium consisting of one of the hormones at two concentrations (FSH: 5 or 10µgmL−1; hCG: 5 or 10IUmL−1; E2: 1 or 5µgmL−1) and for both SOF and TCM base. Each hormone was tested individually for a replicate of eight animals per hormone (total of 12 experimental groups; 24 animals). The COCs were cultured for 72h in their allocated medium and then denuded and stained with Hoechst 33258. Fluorescence microscopy was used to determine nuclear maturation stage. Nuclear maturation rates to MII were analysed using a general linear model with pairwise comparison (SPSS version 25; SPSS Inc./IBM Corp.) with each individual animal acting as a replicate. Canine COCs matured in a SOF-based media had higher rates of meiotic resumption (MI and MII) (SOF: 38.68%, n=515; TCM: 25.78%, n=542; P<0.05) and number reaching MII (SOF: 7.54%; TCM: 4.39%; P<0.05) compared with TCM-based medium. Resumption of meiosis and nuclear maturation to MII did not differ between media with differing E2 or hCG concentrations. The use of FSH at 10µgmL−1 in SOF medium decreased resumption of meiosis (8.57%) and MII rates (0%) compared with 5µgmL−1 FSH in SOF (29.41% and 3.92%, respectively; P<0.05). In summary, our data indicated that higher concentrations of FSH during IVM have a negative effect on meiotic resumption and maturation to MII, whereas canine COCs resume meiosis and mature to MII in higher rates in a SOF-based medium compared with a TCM base. An IVM medium that replicates the invivo environment in which canine COCs mature is beneficial. However, rates of IVM canine oocytes reaching maturity are low, signifying that future research must investigate a greater range of hormone concentrations and combinations to better mimic invivo conditions to assess the possible benefits for canine IVM.

The impact of an epilepsy nurse competency framework on the costs of supporting adults with epilepsy and intellectual disability: findings from the EpAID study

BACKGROUND

The development of a nurse-led approach to managing epilepsy in adults with an intellectual disability (ID) offers the potential of improved outcomes and lower costs of care. We undertook a cluster randomised trial to assess the impact on costs and outcomes of the provision of ID nurses working to a designated epilepsy nurse competency framework. Here, we report the impact of the intervention on costs.

METHOD

Across the United Kingdom, eight sites randomly allocated to the intervention recruited 184 participants and nine sites allocated to treatment as usual recruited 128 participants. Cost and outcome data were collected mainly by telephone interview at baseline and after 6 months. Total costs at 6 months were compared from the perspective of health and social services and society, with adjustments for pre-specified participant and cluster characteristics at baseline including costs. Missing data were imputed using multiple imputation. Uncertainty was quantified by bootstrapping.

RESULTS

The intervention was associated with lower per participant costs from a health and social services perspective of -£357 (2014/2015 GBP) (95% confidence interval -£986, £294) and from a societal perspective of -£631 (95% confidence interval -£1473, £181). Results were not sensitive to the exclusion of accommodation costs.

CONCLUSIONS

Our findings suggest that the competency framework is unlikely to increase the cost of caring for people with epilepsy and ID and may reduce costs.

Diabatic Gates for Frequency-Tunable Superconducting Qubits

We demonstrate diabatic two-qubit gates with Pauli error rates down to 4.3(2)×10^{-3} in as fast as 18 ns using frequency-tunable superconducting qubits. This is achieved by synchronizing the entangling parameters with minima in the leakage channel. The synchronization shows a landscape in gate parameter space that agrees with model predictions and facilitates robust tune-up. We test both iswap-like and cphase gates with cross-entropy benchmarking. The presented approach can be extended to multibody operations as well.

P08.06 Clinical value scores for treatment of newly diagnosed glioblastoma with TTFields

BACKGROUND

High quality and value of recommended treatments is of specific importance in cancer care. ESMO, ASCO and NCCN have developed tools intended to help assessing the clinical value of cancer treatments in a standardised way, allowing for a comparative discussion. Tumor treating fields (TTFields) is a novel, device based cancer treatment, that was recently demonstrated to be effective in newly diagnosed glioblastoma (GBM). This new modality augments the treatments discussed with glioblastoma patients today.

MATERIAL AND METHODS

ESMO and ASCO frameworks each calculate a score for the clinical value of a cancer treatment, called Magnitude of Clinical Benefit Scale (MCBS) by ESMO and the Net Health Benefit (NHB) by ASCO. NCCN self reports “evidence blocks” which are assessed by clinician panels and were recently published for the first line treatment of newly diagnosed GBM with TTFields. We apply and compare the ESMO, ASCO and NCCN tools for TTFields treatment of newly diagnosed GBM.

RESULTS

The resulting ASCO NHB score for TTFields treatment of newly diagnosed GBM is 56. ESMO MCBS scores for TTFields in GBM are resulting in A/5, these being the highest achievable scores for this framework. All frameworks value the increase in overall survival by TTFields and the moderate toxicity profile. ESMO additionally values quality of life, while ASCO values palliation and treatment free intervals. NCCN’s specific focus is on the quality and consistency of the evidence. NCCN evidence blocks also contain an affordability score.

CONCLUSION

All three frameworks consider the clinical efficacy of a treatment and it’s toxicity profile in their clinical value assessment. Beyond that, their respective focus is on slightly different aspects and their definition of clinical value therefore varies in detail. However, all value scores suggest that TTFields treatment of newly diagnosed GBM provides a substantial clinical benefit. The high ESMO and ASCO scores are based on the significantly extended progression free and overall survival for TTFields treated patients, without adding systemic toxicities. The NCCN evidence blocks strongly support the NCCN category 1 recommendation for the use of TTFields in newly diagnosed GBM.

A Hope-Based Intervention to Address Disrupted Goal Pursuits and Quality of Life in Young Adult Cancer Survivors

In this pilot study, we assessed feasibility and acceptability, and obtained efficacy parameters of an app based 8-week program focusing on a hope- based intervention to address the disruption of goal pursuits among young adult cancer survivors in order to ultimately increase quality of life. Methods: This 8-week app-based intervention program, known as AWAKE (Achieving Wellness After Kancer in Early Life), consists of educational videos, mood/activity tracking, and telephone-based coaching to promote goal-oriented thinking and quality of life (QOL) in young adult cancer survivors (YACSs). Fifty-seven YACSs (18–40 years old), two years post treatment were recruited from two NCI-designated cancer centers and randomly assigned to AWAKE (n = 38) or an attention control (n = 19). Both AWAKE and attention control group received weekly coaching calls. The app content for the AWAKE intervention group included 8 weekly modules specifically targeting the needs of young adult cancer survivors; the content delivered via text for those in attention control focused on personal finances. At weeks 0, 8, and 24, we assessed hope (via the Trait Hope Scale) and QOL (via the 36-Item Short Form Health Survey and Functional Assessment of Cancer Therapy-General). Results: The mean age was 32.2 years old, and 75.0% were female, 77.6% non- Hispanic White, 61.2% employed, and 67.3% married/stable union. Diagnoses included breast cancer (28.6%), hematologic malignancies (12.2%), and melanoma (12.2%). Weekly adherence to AWAKE averaged 86.1% (range: 100.0% at week 1 to 75.7% at week 8). Retention at end-of-treatment was 90.7%. Among AWAKE participants, 90.9% were satisfied with AWAKE and would recommend AWAKE to friends with cancer; >84.8% reported that AWAKE components were helpful. Despite being underpowered to detect efficacy, changes in hope and QOL outcomes trended in the hypothesized directions. Conclusion: AWAKE was a feasible and acceptable approach; changes in hope and some measures of QOL trended in the hypothesized direction. AWAKE has the potential to address disrupted goal pursuits and enhance QOL among YACSs. Future research is needed to examine AWAKE's efficacy in a larger RCT.

Using the suture/adhesive strips combination technique for skin closure in an individual with Ehlers-Danlos Syndrome

Combining sutures with adhesive strips to avoid the ‘cheese-wiring’ effect in individuals with fragile skin is a method that has been described previously. Here we demonstrate its application in an individual with Ehlers-Danlos Syndrome.

Robust Chiral Organization of Cellulose Nanocrystals in Capillary Confinement

We showed large area uniformly aligned chiral photonic bioderived films from a liquid crystal phase formed by a cellulose nanocrystal (CNC) suspension placed in a thin capillary. As a result of the spatial confinement of the drying process, the interface between coexisting isotropic and chiral phases aligns perpendicular to the long axis of the capillary. This orientation facilitates a fast homogeneous growth of chiral pseudolayers parallel to the interface. Overall, the formation of organized solids takes hours vs weeks in contrast to the slow and heterogeneous process of drying from the traditional dish-cast approach. The saturation of water vapor in one end of the capillary causes anisotropic drying and promotes unidirectional propagation of the anisotropic phase in large regions that results in chiral CNC solid films with a uniformly oriented layered morphology. Corresponding ordering processes were monitored in situ at a nanoscale, mesoscale, and microscopic scale with complementary scattering and microscopic techniques. The resulting films show high orientation order at a multilength scale over large regions and preserved chiral handedness causing a narrower optical reflectance band and uniform birefringence over macroscopic regions in contrast to traditional dish-cast CNC films and those assembled in a magnetic field and on porous substrates. These thin films with a controllable and well-identified uniform morphology, structural colors, and handedness open up interesting possibilities for broad applications in bioderived photonic nanomaterials.
