A comparison between homemaker prepared meals and traditional home delivered meals on the dietary intake of frail homebound elders

To frail elders, the consumption of nutrients is a challenge. Individuals participating in home delivered meal programs achieve higher daily intakes of key nutrients over non participants. However many elders require special diet and modifications in food texture, features generally not provided by such programs.^ This study compared a pilot program providing individual homemaker prepared meals based on special needs with the traditional home delivered meal program. Eight participants in the model group and 19 participants in the control group completed the 180 day study. The high drop out rate in the model group was due to scheduling difficulties.^ No significant differences existed between the two groups with respect to weight gain/maintenance, macronutrient intake, intake of most micronutrients and customer satisfaction. Homemaker prepared meals is a viable option for individuals needing dietary adjustments. ^

Innovations in dietetic training in foodservice management : can early exposure to practice enhance final year competency development?

Student engagement in the delivery of theoretical course materials is a current challenge in the tertiary sector including for dietetic training. In 2011 with the creation of a new nutritionist position for Queensland Meals on Wheels (QMOW), a service learning approach to support this organisation was used with third year dietetic students undertaking two days of structured activities at various QMOW sites in South East Queensland, aligned with coursework in Foodservice Management (FSM). This cohort of students was then followed in their final year post successful completion of five weeks professional practice in FSM to see if this experience supported readiness for placement and competency development. Evaluation was undertaken of eligible students (n = 50) via paper based survey (response rate 94%) with all participating in targeted focus groups. Findings showed that students acknowledged the QMOW experience (on reflection 14 months later) providing opportunity for participation and/or observation in 5 of 12 FSM areas taught in third year, including food safety, meal production, assembly, delivery and dishwashing. Over half the students identified good exposure to FSM competency areas during the QMOW experience, with 83% satisfied with their competency exposure and subsequent practice during final year placements. A consistent theme emerged from focus groups supporting inclusion of practical opportunities with the theoretical component of the FSM subject to highlight relevance to learning. These findings highlight the importance of such teaching initiatives to met student learning preferences, linking theory with practice and supporting competency development in the final year of training programs.

The impact of an educational DVD on pregnant women with gestational diabetes mellitus: a randomised controlled trial

Background The diagnosis of gestational diabetes (GDM) during pregnancy can lead to anxiety. Little research has focused on the education these women receive and how this is best delivered in a busy clinic. Aim This study evaluated the impact of an innovative patient-centred educational DVD on anxiety and glycaemic control and in newly diagnosed women with GDM. Method 150 multi-ethnic women, aged 19-44 years, from three UK hospitals were randomised to either standard care plus DVD (DVD group, n=77) or standard care alone (control group, n=73) at GDM diagnosis. Women were followed up at their next clinic visit at a mean ± SD of 2.5 ± 1.6 weeks later. Primary outcomes were anxiety (State-Trait Anxiety Inventory) and mean 1-hour postprandial capillary self-monitored blood glucose for all meals, on day prior to follow-up. Secondary outcomes included pregnancy specific stress (Pregnancy Distress Questionnaire), emotional adjustment to diabetes (Appraisal of Diabetes Scale), self-efficacy (Diabetes Empowerment Scale) and GDM knowledge (non-validated questionnaire). Other outcomes included mean fasting and 1-hour postprandial blood glucose at each meal, on day prior to follow-up. Women in the DVD group completed a feedback questionnaire on the resource. Results No significant difference between the DVD and control group were reported, for anxiety (37.7 ± 11.7 vs 36.2 ± 10.9; mean difference after adjustment for covariates (95%CI) 2.5 (-0.8, 5.9) or for mean 1-hour postprandial glucose (6.9 ± 0.9 vs 7.0 ± 1.2 mmol/L; -0.2 (-0.5, 0.2). Similarly, no significant differences in the other psychosocial variables were identified between the groups. However, the DVD group had significantly lower postprandial breakfast glucose compared to the control group (6.8 ± 1.2 vs 7.4 ± 1.9 mmol/L; -0.5 (-1.1, -<0.1; p=0.04). Using a scale of 0-10, 84% rated the DVD 7 or above for usefulness (10 being very useful), and 88% rated it 7 or above when asked if they would recommend to a friend (10 being very strongly recommend). Women described the DVD as ‘reassuring’, ‘a fantastic tool’, that ‘provided a lot of information in a quick and easy way’ and ‘helped reinforce all the information from clinic’. Discussion While no significant change was observed in anxiety or mean postprandial glucose, the DVD was rated highly by women with GDM and may be a useful resource to assist with educating newly diagnosed women.

Postprandial lipid and hormone responses to meals of varying fat contents: modulatory role of lipoprotein lipase?

OBJECTIVE: Substrate and hormone responses to meals of differing fat content were evaluated in normal subjects in order to investigate mechanisms underlying the regulation of postprandial lipoprotein concentration. DESIGN: A randomised cross-over study with three different meals on three occasions. SETTING: Free-living subjects associated with Surrey University. SUBJECTS: Ten male volunteers (aged 18-23 years) were recruited. INTERVENTIONS: Three test meals containing 20, 40 or 80 g fat but identical carbohydrate and protein content were randomly allocated to volunteers. MAJOR OUTCOME MEASURES: Pre- and postprandial blood samples were taken for the analysis of plasma triacylglycerol, non-esterified fatty acids, glucose, immunoreactive insulin and glucose-dependent insulinotrophic polypeptide levels and postheparin lipoprotein lipase activity measurements. RESULTS: Peak triacylglycerol concentrations and lipoprotein lipase activity measurements were significantly higher following the 80 g than the 20 g fat meal (P = 0.009 and P = 0.049 respectively). Areas under the glucose-dependent insulinotrophic polypeptide time-response concentration curves were significantly higher following the 80 g compared with the 20 g fat meal (P = 0.04), but no differences in insulin response to the meals were seen. The 30-360 min decrease in the non-esterified fatty acid concentration was less following the 80 g than the 20 g meal (P = 0.001). CONCLUSIONS: The results suggest that glucose-dependent insulinotrophic polypeptide may mediate increased lipoprotein lipase activity in response to fat-containing meals and may play a role in circulating lipoprotein homeostasis. This mechanism may be overloaded with high fat meals with adverse consequences on circulating triacylglycerol and NEFA concentrations.

Polyunsaturated fatty acids of the n-6 and n-3 series: effects on postprandial lipid and apolipoprotein levels in healthy men

OBJECTIVE: The present study was carried out to determine effects of test meals of different fatty acid compositions on postprandial lipoprotein and apolipoprotein metabolism. DESIGN: The study was a randomized, single blind design. SETTING: The study was carried out in the Clinical Investigation Unit of the Royal Surrey County Hospital. SUBJECTS: Twelve male normal subjects with an average age of 22.4 +/- 1.4 years (mean +/- SD) were selected from the student population of the University of Surrey; one subject dropped out of the study because he found the test meal unpalatable. INTERVENTIONS: The subjects were given three evening test meals on three separate occasions, in which the oils used were either a mixed oil (rich in saturated fatty acids and approximated the fatty acid intake of the current UK diet), corn oil (rich in n-6 fatty acids), or fish oil (rich in n-3 fatty acids) 40 g of the oil under investigation were incorporated into a rice-based test meal. Triacylglycerol-rich lipoproteins-triacylglycerol (TRL-TAG), TRL-cholesterol (TRL-cholesterol), plasma-TAG, plasma cholesterol (T-C), and serum apolipoprotein A-I and B (apo A-I and B) responses were measured. Postprandial responses were followed for 11 h. RESULTS: Postprandial plasma-TAG responses, calculated as incremental areas under the response curves (IAUC) were significantly reduced following the fish oil meal [365.5 +/- 145.4 mmol/l x min (mean +/- SD)[ compared with the mixed oil meal (552.0 +/- 141.7 mmol/l x min) (P < 0.05) and there was a strong trend towards the same direction in the TRL-TAG responses. In all instances, plasma-and TRL-TAG showed a biphasic response with increased concentrations occurring at 1h and between 3 and 7h postprandially. TRL-cholesterol, T-C, and serum apo A-I and B responses to the three meals were similar. CONCLUSIONS: The findings support the view that fish oils decrease postprandial lipaemia and this may be an important aspect of their beneficial effects in reducing risk of coronary heart disease (CHD). Further work is required to determine the mechanisms responsible for this effect.

Aims: The recent conversations about disappearing family meals, mental problems of the youngsters and family meals´ protective effect on youngsters problems have been the base of this study. The main aim of this study is to find out, what kind of position family meals do have in the youngsters´lives. Study questions are: 1. What kind of conceptions youngsters have of family meals? 2. What kind of hands-on experience youngsters have about family meals? 3. How youngsters feel family meals on a emotional level? a. Are meals positive moments with the family or do they just limit timetables? b. Do the youngsters need family meals if they do not have those in their families? Why? Why not? Methods: The data was collected using stimulated recall -interviews and basic themed interviews. The data was collected from thirteen 8th graders from Pirkanmaa and Kanta-Häme. The interviews were analyzed with the qualitative content analysis. Results and conclusion: The youngsters´ consepts of the meals and the family meals were quite traditional, assuming that those are warm, varied and eaten with company. The situation of the family meals was good and those were eaten nearly every day in the most of the families. The youngsters thought that the family meals were important social moments with the family and they were able to talk about important things with the family during the meals. They also felt that the daily eating rythm was good and they did not felt that the meals would have been somehow restrictive. Even so that the pupils felt the family meals were important, the pupil whose family did not eat family meals did not long those meals. He felt that he was able to share his thoughts and experiences also in other ways. It is important that youngsters have this channel of communication.

The Triveneto transhumance: law, land, movement

North Italy's nomadic shepherds are a phenomenon unique in the world. Their nomadic nature is taken to the extreme since they move constantly rather than solely in the winter or the summer, as in the usual nomadism. Their home is on wheels and their territory is the tightly regulated yet sprawling Triveneto area. The Triveneto transhumance moves beyond private/public property divides, and indeed beyond lawful/unlawful distinctions, giving rise to what I have called an animal normativity. Relying on Valentina De Marchi's text 'Fame d'Erba' on the Triveneto transhumance, I show how territory becomes a question of animal hunger, and movement becomes an atmospheric, silent and imperceptible affect that crosses private property boundaries, state law limitations, reservation areas and road networks. This way of being, beyond the usual distinctions, offers an example of an alternative political and legal organisation that brings forth the continuum between the human, the natural and the legal/political.

Efeitos do exercício voluntario na recuperação de hemissecção da medula espinhal: mudanças na rede perineuronal e acetilação de histonas

A prática regular de exercícios físicos previne e combate várias doenças ao longo do tempo, destacando-se como excelente ferramenta terapêutica para o tratamento de lesões no sistema nervoso central (SNC). Após uma transecção (completa ou incompleta/hemissecção) da medula espinhal, células gliais reativas secretam substâncias inibitórias à regeneração axonal como, por exemplo, as moléculas de proteoglicanas de sulfato de condroitina (PGSCs) que exercem papel importante na formação de uma barreira físico-química, chamada cicatriz glial, que impede o crescimento dos axônios danificados pela lesão. Pesquisas que envolvem modelo experimental de lesão da medula espinhal e reabilitação por exercício físico têm obtido promissores resultados. No entanto, os mecanismos fisiológicos e moleculares pelos quais promovem esses resultados positivos ainda são pouco conhecidos. O objetivo do presente trabalho foi analisar a recuperação da função motora da pata posterior após protocolo de exercício físico voluntario em modelo experimental de hemissecção da medula espinhal e investigar dois mecanismos moleculares envolvidos na recuperação funcional: a degradação de PGSCs nas redes perineuronais e acetilação de histonas. Para isso, vinte e quatro (24) ratos da linhagem Wistar (Rattus novergicus) foram utilizados e separados em 3 grupos (controle, treinados e não treinados). Com exceção do grupo controle, todos os animais foram habituados a rodas de corridas e em seguidas foram submetidos a uma cirurgia experimental de hemissecção da medula espinhal, na altura da 8a vertebra torácica. Nossos resultados demonstraram que o exercício voluntário em rodas de corrida após lesão experimental da medula espinhal promoveu recuperação da função motora da pata posterior afetada, porém não observamos diferenças qualitativas na acetilação de histonas e degradação de PGSCs entre os grupos.

DESIGN OF EFFICIENT IN-NETWORK DATA PROCESSING AND DISSEMINATION FOR VANETS

By providing vehicle-to-vehicle and vehicle-to-infrastructure wireless communications, vehicular ad hoc networks (VANETs), also known as the “networks on wheels”, can greatly enhance traffic safety, traffic efficiency and driving experience for intelligent transportation system (ITS). However, the unique features of VANETs, such as high mobility and uneven distribution of vehicular nodes, impose critical challenges of high efficiency and reliability for the implementation of VANETs. This dissertation is motivated by the great application potentials of VANETs in the design of efficient in-network data processing and dissemination. Considering the significance of message aggregation, data dissemination and data collection, this dissertation research targets at enhancing the traffic safety and traffic efficiency, as well as developing novel commercial applications, based on VANETs, following four aspects: 1) accurate and efficient message aggregation to detect on-road safety relevant events, 2) reliable data dissemination to reliably notify remote vehicles, 3) efficient and reliable spatial data collection from vehicular sensors, and 4) novel promising applications to exploit the commercial potentials of VANETs. Specifically, to enable cooperative detection of safety relevant events on the roads, the structure-less message aggregation (SLMA) scheme is proposed to improve communication efficiency and message accuracy. The scheme of relative position based message dissemination (RPB-MD) is proposed to reliably and efficiently disseminate messages to all intended vehicles in the zone-of-relevance in varying traffic density. Due to numerous vehicular sensor data available based on VANETs, the scheme of compressive sampling based data collection (CS-DC) is proposed to efficiently collect the spatial relevance data in a large scale, especially in the dense traffic. In addition, with novel and efficient solutions proposed for the application specific issues of data dissemination and data collection, several appealing value-added applications for VANETs are developed to exploit the commercial potentials of VANETs, namely general purpose automatic survey (GPAS), VANET-based ambient ad dissemination (VAAD) and VANET based vehicle performance monitoring and analysis (VehicleView). Thus, by improving the efficiency and reliability in in-network data processing and dissemination, including message aggregation, data dissemination and data collection, together with the development of novel promising applications, this dissertation will help push VANETs further to the stage of massive deployment.
