RESUMO

BACKGROUND: To explore the barriers and enablers experienced by nutrition and dietetic professionals in the implementation of the standardised Nutrition Care Process (NCP) across 10 different countries. NCP related beliefs, motivations and values were investigated and compared. METHODS: A validated online survey was disseminated to nutrition and dietetics professionals in 10 countries in the local language during 2017. Cross-sectional associations and differences between countries were explored for level of implementation, barriers/enablers and attitudes/motivation among the respondents. RESULTS: Higher NCP implementation was associated with greater occurrence of enabling aspects, as well as fewer occurrences of barriers. The most common enabler was 'recommendation by the national dietetic association' (69%) and the most common barrier was 'lack of time' (39%). A longer experience of NCP use was associated with a more positive attitude towards all NCP aspects. Differences between countries were identified, regarding both the occurrence of barriers/enablers and attitudes/motivations. CONCLUSIONS: Implementation efforts need to be tailored to country-specific contexts when implementing a new standard of care framework among nutrition and dietetic professionals. Additional research is needed to further assess the management and workplace strategies to support the development of nutrition and dietetics professionals in multidisciplinary healthcare organisations.

RESUMO

BACKGROUND: Smartphone health applications (apps) and other mobile health (mHealth) technologies may assist dietitians in improving the efficiency of patient care. The present study investigated the use of health apps and text messaging in dietetic practice and formulated intervention recommendations for supporting app uptake by dietitians based on the behavioural 'COM-B' system, where interactions between capability, opportunity and motivation influence behaviour. METHODS: A 52-item online survey tool, taking 20 min to complete, was developed and piloted, with questions exploring the use of health apps and text messaging in dietetic practice, types of apps dietitians recommended and that patients used, and barriers and enablers to app use in dietetic practice. The Australian, New Zealand and British dietetic associations distributed the survey to their members. RESULTS: A 5% response rate was achieved internationally, with 570 completed responses included for further analysis. Health apps, namely nutrition apps, were used by 62% of dietitians in their practice, primarily as an information resource (74%) and for patient self-monitoring (60%). The top two nutrition apps recommended were MyFitnessPal® (62%) and the Monash University Low FODMAP Diet® (44%). Text messaging was used by 51% of respondents, mainly for appointment-related purposes (84%). CONCLUSIONS: Although the reported use of smartphone health apps in dietetic practice is high, health apps and other mHealth technologies are not currently being used for behaviour change, nor are they an integral part of the nutrition care process. Dietetic associations should provide training, education and advocacy to enable the profession to more effectively engage with and implement apps into their practice.

RESUMO

We present the design, description, calibration procedure, and an analysis of systematic effects for an apparatus designed to measure the rotation of the plane of polarization of a transversely polarized slow neutron beam as it passes through unpolarized matter. This device is the neutron optical equivalent of a crossed polarizer/analyzer pair familiar from light optics. This apparatus has been used to search for parity violation in the interaction of polarized slow neutrons in matter. Given the brightness of existing slow neutron sources, this apparatus is capable of measuring a neutron rotary power of dϕ/dz = 1 × 10(-7) rad/m.

RESUMO

BACKGROUND: Skeletal muscle depletion (sarcopenia) predicts morbidity and mortality in the elderly and cancer patients. METHODS: We tested whether sarcopenia predicts primary colorectal cancer resection outcomes in stage II-IV patients (n=234). Sarcopenia was assessed using preoperative computed tomography images. Administrative hospitalisation data encompassing the index surgical admission, direct transfers for inpatient rehabilitation care and hospital re-admissions within 30 days was searched for International Classification of Disease (ICD)-10 codes for postoperative infections and inpatient rehabilitation care and used to calculate length of stay (LOS). RESULTS: Overall, 38.9% were sarcopenic; 16.7% had an infection and 9.0% had inpatient rehabilitation care. Length of stay was longer for sarcopenic patients overall (15.9 ± 14.2 days vs 12.3 ± 9.8 days, P=0.038) and especially in those ≥ 65 years (20.2 ± 16.9 days vs 13.1 ± 8.3 days, P=0.008). Infection risk was greater for sarcopenic patients overall (23.7% vs 12.5%; P=0.025), and especially those ≥ 65 years (29.6% vs 8.8%, P=0.005). Most (90%) inpatient rehabilitation care was in patients ≥ 65 years. Inpatient rehabilitation was more common in sarcopenic patients overall (14.3% vs 5.6%; P=0.024) and those ≥ 65 years (24.1% vs 10.7%, P=0.06). In a multivariate model in patients ≥ 65 years, sarcopenia was an independent predictor of both infection (odds ratio (OR) 4.6, (95% confidence interval (CI) 1.5, 13.9) P<0.01) and rehabilitation care (OR 3.1 (95% CI 1.04, 9.4) P<0.04). CONCLUSION: Sarcopenia predicts postoperative infections, inpatient rehabilitation care and consequently a longer LOS.

RESUMO

BACKGROUND & AIMS: Extensive loss of adipose tissue is a key feature of cancer cachexia. Advanced cancer patients also exhibit low plasma phospholipids. It is not known whether these processes coincide across the cancer trajectory nor has their relationship with survival been defined. Changes in adipose tissue mass and plasma phospholipids were characterized within 500days prior to death and prognostic significance assessed. METHODS: Adipose tissue rate of change was determined in a retrospective cohort of patients who died of colorectal and lung cancers (n=108) and who underwent >2 computed tomography scans in the last 500days of life. Plasma phospholipid fatty acids were measured prospectively in a similar cohort of patients with metastatic cancer (n=72). RESULTS: Accelerated loss of adipose tissue begins at 7months from death reaching an average loss of 29% of total AT 2months from death. Plasma phospholipid fatty acids were 35% lower in patients closest to death versus those surviving >8months. Losses of phospholipid fatty acids and adipose tissue occur in tandem and are predictive of survival. CONCLUSIONS: Depletion of plasma phospholipids likely indicates a deficit of essential fatty acids in the periphery which may contribute to loss of adipose tissue.
