Nutrition screening practices amongst Australian residential aged care facilities

ObjectivesTo determine the proportion of Residential Aged Care Facilities (RACFs) in Australia who use a nutrition screening tool on residents to identify those at risk of malnutrition, and to review practice following identification of residents as being at high risk of malnutrition.DesignMulti-center, cross sectional observational study. Setting: Residential Aged Care Facilities.ParticipantsThe Director of Nursing at each site was contacted by telephone and asked questions relating to current nutrition screening practices at their residential aged care facility.MeasurementsData was collected from a stratified sample of 229 residential aged care facilities in each state and territory in Australia.Results82% of RACFs (n = 188) use a nutrition screening tool on residents to identify those at risk of malnutrition, however only 52% of RACFs (n = 119) used a screening tool which is validated in the residential aged care setting. There was a significant association between facilities using a nutrition screening tool and the staff members being trained to conduct nutrition screening (p < 0.001). Facilities that employed a dietitian were more likely to use a validated nutrition screening tool (p < 0.005). The most frequently used nutrition screening tool was the ‘Mini Nutritional Assessment–Short Form (MNA-SF)’, which was used by 32% (n = 60) of the RACFs, followed by the ‘Malnutrition Universal Screening Tool (MUST)’ (15%, n = 29).ConclusionWe found that the majority of RACFs in Australia use a nutrition screening tool, however many of these RACFs use a tool which has not been validated in the RACF setting. This study highlights the need for greater dietetic advocacy in using validated nutrition screening tools to ensure malnutrition is identified.

Malnutrition: The Importance of Identification, Documentation, and Coding in the Acute Care Setting

Malnutrition is a significant issue in the hospital setting. This cross-sectional, observational study determined the prevalence of malnutrition amongst 189 adult inpatients in a teaching hospital using the Patient-Generated Subjective Global Assessment tool and compared data to control groups for coding of malnutrition to determine the estimated unclaimed financial reimbursement associated with this comorbidity. Fifty-three percent of inpatients were classified as malnourished. Significant associations were found between malnutrition and increasing age, decreasing body mass index, and increased length of stay. Ninety-eight percent of malnourished patients were coded as malnourished in medical records. The results of the medical history audit of patients in control groups showed that between 0.9 and 5.4% of patients were coded as malnourished which is remarkably lower than the 52% of patients who were coded as malnourished from the point prevalence study data. This is most likely to be primarily due to lack of identification. The estimated unclaimed annual financial reimbursement due to undiagnosed or undocumented malnutrition based on the point prevalence study was AU

The effects of the Mediterranean diet on rheumatoid arthritis prevention and treatment: a systematic review of human prospective studies

8,536,200. The study found that half the patients were malnourished, with older adults being particularly vulnerable. It is imperative that malnutrition is diagnosed and accurately documented and coded, so appropriate coding, funding reimbursement, and treatment can occur.

Effect of long-term nutraceutical and dietary supplement use on cognition in the elderly: a 10-year systematic review of randomised controlled trials

Rheumatoid arthritis is a progressive autoimmune disease characterised by severely swollen and painful joints. To compliment pharmacotherapy, people living with rheumatoid arthritis often turn to dietary interventions such as the Mediterranean diet. The aim of the present systematic review is to discuss the effects of the Mediterranean diet on the management and prevention of rheumatoid arthritis in human prospective studies. Four studies met the inclusion criteria, including two intervention studies reporting improvement in the pain visual analogue scale (p < 0.05) and a decrease in the health assessment questionnaire for rheumatoid arthritis score (p < 0.05) in the Mediterranean diet groups. Only one study reported a reduction in the 28 joint count disease activity score for rheumatoid arthritis for the Mediterranean diet group (p < 0.05). This review has identified beneficial effects of the Mediterranean diet in reducing pain and increasing physical function in people living with rheumatoid arthritis. However, there is currently insufficient evidence to support widespread recommendation of the Mediterranean diet for prevention of rheumatoid arthritis.

Survey of disability-related content in Australian dietetics programs: Disability content of dietetics programs

Nutraceuticals have generated interest as a way to mitigate the cognitive decline in older adults. The aim of this systematic review was to determine the evidence for these claims from the scientific literature in randomised, double-blinded, controlled trials (duration: ≥1 year; participants: n≥100; age(mean): ≥65 years). Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched four electronic databases (PubMed, Scopus, CINAHL and Web of Science) and identified twenty-five studies published between the 15·June·2006 and 14·June·2016. Interventions included B-vitamins, n-3 fatty acids, antioxidant vitamins and herbs. Of the B-vitamin studies, four found benefits to cognition with supplementation. The first of these B-vitamin studies, in individuals with mild cognitive impairment (n 266; duration=2 years), included benefit to executive function (P=0·015) and improvements in the Mini-Mental State Examination (MMSE) among participants with baseline homocysteine above 11·3 µmol/l (P<0·001). In the same sample, the second study found cognitive benefits of B-vitamins dependent on the higher baseline plasma n-3 fatty acid status. The third B-vitamin study (n 900; duration=2 years) reported improved performance in immediate (P=0·046) and delayed recall (P=0·013), whereas the fourth study (n 856; duration=2 years) reported slower rate of cognitive decline in the MMSE (P=0·05). One study investigating DHA treatment (n 402; duration=1·5 years) revealed the slower rate of cognitive change in apoE e4 non-carriers (P=0·03). As only five included studies revealed notable benefits, presently based on the specific compounds explored here, there is not compelling evidence to support the use nutraceuticals to improve cognition in the elderly. Future long-term trials of nutraceuticals should investigate interactions with lifestyle, blood biomarkers and genetic risk factors.

Association between siesta (daytime sleep), dietary patterns and the presence of metabolic syndrome in elderly living in Mediterranean area (MEDIS study): The moderating effect of gender

AIM Nutrition and dietetic services are an important component of healthcare for people living with a disability. The introduction of the National Disability Insurance Scheme (NDIS) in Australia is providing more opportunities for individuals to access these services from an Accredited Practising Dietitian (APD). The aim of this research was to identify how students in Australian tertiary dietetics programs are being prepared to provide these services to people with a disability. METHODS A purpose-built questionnaire with eight open-ended questions was developed by the researchers to describe the disability-related content of university and professional placement learning opportunities and was distributed to all course conveners (or their nominated representative) of dietetics programs accredited by the Dietitians Association of Australia. The qualitative data were analysed using a descriptive approach. Responses were sorted into response category themes and counted to identify common themes. RESULTS A representative from 14 of 18 programs (78% response rate) participated in the survey in September and October 2016. Results indicated that although 12 programs incorporate disability-related topics into the curriculum, content was inconsistent and of varying depths. Four programs offered a disability-specific placement opportunity and nine discussed the NDIS to varying degrees. CONCLUSIONS It is important that graduates are provided with adequate learning opportunities in the area of disability to ensure that they are prepared for entry-level practise in this area. Further research may provide insight into the skills, knowledge and behaviours used by APDs working in disability to identify those that need to be strengthened in dietetics programs.

Malnutrition Prevalence in Aged Care Residents: A Pilot Study

ObjectivesSeveral lifestyle parameters including diet, physical activity and sleep were associated in isolation with the presence of Metabolic Syndrome (MetS) in adults, to date there is a paucity of studies which evaluated their combined role aging populations and especially with respect to gender. Therefore, the aim of the present study was to provide a global consideration of the lifestyle factors associated with MetS among elderly individuals.DesignCross-sectional observational study.Setting21 Mediterranean islands and the rural Mani region (Peloponnesus) of Greece.Participantsduring 2005-2015, 2749 older (aged 65-100 years) from were voluntarily enrolled in the study.MeasurementsDietary habits, energy intake, physical activity status, sociodemographic characteristics, lifestyle parameters (sleeping and smoking habits) and clinical profile aspects were derived through standard procedures. The presence of MetS was defined using the definition provided by NCEP ATP III (revised) and cluster analysis was used to identify overall dietary habit patterns.ResultsThe overall prevalence of MetS in the study sample was 36.2%, but occurred more frequently in females (40.0% vs. 31.8%, respectively, p=0.03). Individuals with MetS were more likely to sleep during the day (89.4% vs. 76.8% respectively, p=0.039) and frequent ‘siesta’ was positively linked to the odds of MetS presence in females (Odds Ratio (OR) =3.43, 95% Confidence Intervals (CI): 1.08-10.9), but not for men (p=0.999). The lower carbohydrate (i.e., 45.2% of total daily energy, 120±16gr/day) dietary cluster was inversely associated with the odds for MetS presence, but only for men (OR=0.094, 95%CI: 0.010-0.883).ConclusionsLifestyle parameters including sleep and diet quality are strongly associated with the presence of MetS in elderly cohort, but different their level of influence appears to be different, depending on gender. Further research is needed to better consider the role of lifestyle characteristics in the management of MetS in clinical practice.

Effect of Folate Supplementation on Inflammatory Markers in Individuals Susceptible to Depression: A Systematic Review

Malnutrition is a significant clinical and public health problem. The prevalence of malnutrition was determined in a sample of older people living in 2 residential aged care facilities in Australia. The Subjective Global Assessment tool was used to determine the prevalence of malnutrition in 57 residents. The majority of residents were well nourished (67), 26 moderately malnourished, and 7 severely malnourished. Prevalence of malnutrition was higher for those receiving high-level care (42), but this was not statistically significant (P =.437). No relationship was found between malnutrition status and age (P =.529) or sex (P =.839).

l-Theanine as a Functional Food Additive: Its Role in Disease Prevention and Health Promotion

Folate has been proposed to be an efficacious treatment strategy for depression. The mandatory fortification of flour with synthetic folic acid (FA) in over 80 countries has yielded improvements in folate intake; however, depression is still a considerable public health concern. While there are established benefits of FA fortification in reducing risk of neural tube defects, the implications regarding depression are unclear, especially in individuals with certain genetic polymorphisms. Therefore, a systematic review was conducted to examine the effects of folate to treat depression. Following PRISMA guidelines, a systematic review was conducted of electronic databases (PUBMED, Scopus, CINAHL, and Cochrane Library) to identify human clinical trials examining the effects of folate (including FA) supplementation in the management or prevention of depression, the impact on inflammatory markers and if genetic polymorphisms were considered. Ten trials met the inclusion criteria. Seven trials examined effects of either adjunctive FA or L-methylfolate (L-MTHF) supplementation with antidepressants in the management of depression and three examined effects of FA supplementation alone for prevention of depression. No benefit of FA was found compared to placebo (all, p > 0.05). The single L-MTHF trial that explored the interplay of genetic polymorphisms and methylation status found benefit in the Hamilton depression rating scale from adjunctive treatment with 15 mg/day of L-MTHF compared with placebo (−6.8 ± 7.2 vs. −3.7 ± 6.5; p = 0.017) and improvement with L-MTHF for most genetic markers. Currently, there is no evidence to support FA supplementation for the management or prevention of depression. More research is required to determine the efficacy of L-MTHF and folinic acid in certain clinical populations.
