RESUMEN

Qualitative research methods are increasingly used in nutrition and dietetics research. Ethnography is an underexploited approach which seeks to explore the diversity of people and cultures in a given setting, providing a better understanding of the influences that determine their choices and behaviours. It is argued that traditional ethnography, that is, the methodology of living within participant communities, is a dated practice, with roots in colonialism, accessible to only researchers with the means, connections and status to conduct such research, typically white, privileged males. This paper proposes a formal interpretation of 'patchwork ethnography', whereby research is carried out in situ around existing modern-day commitments of the researcher, thus enabling more researchers within health, nutrition and dietetic practice to benefit from the rich data that can be discovered from communities. This review proposes the concept that pragmatic patchwork ethnography is required, proposing a framework for implementation, providing researchers, particularly within the fields of human nutrition, dietetics and health, the accessibility and means to deploy a meaningful client-centric methodology. We present pragmatic patchwork ethnography as a modern method for use within multiple healthcare settings, thus adding a progressive brick in the wall of qualitative research.

RESUMEN

This paper evaluated analytical methods used to generate time-series data from elephant tail hairs, which can be used to reflect changing exposure to environmental geochemistry. Elephant tail hairs were analysed by three methods sequentially, each providing data to inform subsequent analysis. Scanning Electron Microscopy (SEM) and X-ray Microanalysis visually showed the structure of the hair, specific structures such as tubules, and the mineral crusting around the edge of the hair, informing targeting of subsequent analysis by Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). LA-ICP-MS generated time-series data which informed sectioning of the tail hairs for subsequent quantitative analysis for potentially toxic elements and micronutrients using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) of dissolved tail hairs. This novel approach to characterise the tail hair enabled time-series analysis to reflect changes in environmental exposure which may result from seasonal or geochemical spatial variation and could inform elephant movement patterns. The seasonal change between wet and dry seasons was reflected down the length of the hair. Correlations were seen between LA-ICP-MS data and ICP-MS data in several elements including Mg, P, Ca, Fe, Na, Mn and U. This study provided time-series data for the analysis of elephant tail hairs by evaluating analytical challenges to obtaining quantitative data, such as improving protocols to ensure removal of extraneous material, determining where to section the tail hairs to best reflect environmental changes/exposure and ensuring representative analyses. A protocol was established to determine mineral status across a 12-18 month time period utilizing single elephant tail hairs.

RESUMEN

The prevalence of overweight and obesity is rising in all parts of the world and, among young women, it presents a very clear danger during pregnancy. Women who are overweight or who gain excessive weight during pregnancy are at greater risk of complications in pregnancy and labour, and are more likely to lose their child to stillbirth or die themselves during pregnancy. This narrative review considers the evidence that, in addition to increasing risk of poor pregnancy outcomes, obesity has the capacity to programme foetuses to be at greater risk of cardiometabolic disorders later in life. An extensive body of evidence from prospective and retrospective cohorts, as well as record linkage studies, demonstrates associations of maternal obesity and/or gestational diabetes with cardiovascular disease, as well as type 1 and type 2 diabetes. Studies in animals suggest that these associations are underpinned by adaptations that occur in foetal life, which remodel the structures of major organs, including the brain, kidney and pancreas.

RESUMEN

The global prevalence of overweight and obesity in pregnancy is rising and this represents a significant challenge for the management of pregnancy and delivery. Women who have a pre-pregnancy body mass index greater than 25 kg m-2 are more likely than those with a body mass index in the ideal range (20-24.99 kg m-2 ) to have problems conceiving a child and are at greater risk of miscarriage and stillbirth. All pregnancy complications are more likely with overweight, obesity and excessive gestational weight gain, including those that pose a significant threat to the lives of mothers and babies. Labour complications arise more often when pregnancies are complicated by overweight and obesity. Pregnancy is a stage of life when women have greater openness to messages about their lifestyle and health. It is also a time when they come into greater contact with health professionals. Currently management of pregnancy weight gain and the impact of overweight tends to be poor, although a number of research studies have demonstrated that appropriate interventions based around dietary change can be effective in controlling weight gain and reducing the risk of pregnancy complications. The development of individualised and flexible plans for avoiding adverse outcomes of obesity in pregnancy will require investment in training of health professionals and better integration into normal antenatal care.

RESUMEN

BACKGROUND: A baby-led approach to weaning (BLW) encompasses self-feeding and self-selecting graspable foods, offering an alternative to traditional weaning (TW). This cross-sectional study explored adherence to characteristics of BLW and differences in food group exposure and nutrient intake between babies following either TW or BLW. METHODS: Nutritional data were collected via multiple-pass 24-h recall, following parental completion of an online survey. RESULTS: Infants were grouped according to age (6-8 months; TW [n = 36] and BLW [n = 24]) and (9-12 months; TW [n = 24] and BLW [n = 12]). BLW babies were more likely to be breast fed (p = 0.002), consumed a higher percentage of foods also consumed by their mother (p = 0.008) and were fed less purees (p < 0.001) at 6-8 months. TW babies were spoon fed more (p ≤ 0.001) at all ages. Amongst babies aged 6-8 months, total intake (from complementary food plus milk) of iron (p = 0.021), zinc (p = 0.048), iodine (p = 0.031), vitamin B12 (p = 0.002) and vitamin D (p = 0.042) and both vitamin B12 (p = 0.027) and vitamin D (p = 0.035) from complementary food alone was higher in babies following TW. Compared to TW, BLW babies aged 6-8 months had a higher percentage energy intake from fat (p = 0.043) and saturated fat (p = 0.026) from their milk. No differences in nutrient intake were observed amongst infants aged 9-12 months. Few differences were observed between groups in their number of exposures to specific food groups. CONCLUSIONS: TW infants had higher intakes of key micronutrients at 6-8 months, although there were few differences in nutritional intake at 9-12 months or food group exposure between babies following TW or BLW. BLW appears to be socially desirable. Guidance for parents is required, along with larger, longer-term studies, which explore the potential impact of BLW in later childhood.

RESUMEN

The cafeteria diet (CD), an experimental diet that mimics the obesogenic Western diet, can impair memory in adult rats. However, the suckling period is also particularly susceptible to diet-induced behavioural modification. Here, following exposure to CD feeding during lactation, 24- to 26-day-old offspring were tested to determine maternal dietary effects on either open field habituation, object location (OL) learning or on recency learning. Whereas no impact on habituation learning could be demonstrated, both OL and recency memory were impaired. In controls (C), OL memory was shown both after a 5 min (p < .05) or 60 min (p < .001) inter-trial interval (ITI). After the 60 min ITI, the difference between C and CD was significant (p < .05). Learning did not occur in the CD group at any time point and was not observed after the 24hr ITI in in either group. Whereas control rats demonstrated intact recency memory (p < .00001), no learning occurred in the CD group. Both groups differed significantly in their exploration ratios (p < .01). This study suggests a detrimental effect of exposure to an unhealthy Western diet during lactation, on cognitive functions in adolescent rats. These results could have implications for human cognition in the context of obesity epidemic.

RESUMEN

OBJECTIVES: This is the first study to focus on the role and impact of a psychosocial intervention, the Meeting Centre Support Programme (MCSP), for people living with dementia and mild cognitive impairment (MCI) on the experience of stigmatisation across three different European countries. METHOD: A pre/post-test control group study design compared outcomes for 114 people with dementia (n=74) and MCI (n=40) in Italy, Poland and the UK who received either the MCSP or usual care (UC). The 'Stigma Impact Scale, neurological disease' (SIS) was administered at two points in time, 6 months apart. The Global Deterioration Scale (GDS) was used to assess the level of cognitive impairment. RESULTS: Although statistical analysis did not show any significant differences between MCSP and UC at pre/post-test for the 3 countries combined, there were significant results for individual countries. In Italy, the level of SIS was significantly lower (p=0.02) in the MCSP group following the intervention. The level of Social Isolation increased significantly (p=0.05) in the UC group at follow-up in Poland. The level of Social Rejection was significantly higher (p=0.03) over time for UK participants receiving MCSP compared to UC. CONCLUSION: The experience of stigma by people living with dementia and MCI is complex and there may be different country specific contexts and mechanisms. The results do not enable us to confirm or disconfirm the impact of a social support programme, such as MCSP, on this experience. Difficulties in directly measuring the level of stigma in this group also requires further research.

RESUMEN

BACKGROUND: The Meeting Centres Support Programme (MCSP) offers a combined approach to providing practical, emotional and social support to people living with mild to moderately severe dementia and their family carers in the community. METHODS: A mixed methods explanatory design was used. The evaluation took place within the framework of the international Joint Programme - Neurodegenerative Disease Research (JPND) - MEETINGDEM study in nine Meeting Centres in Italy, Poland and the United Kingdom. Eighty-seven people with dementia and 81 family carers completed a user evaluation survey after three months and 83 people with dementia and 84 carers after 6 months of participation in MCSP. Thirty-two people with dementia and 30 carers took part in focus groups after nine months. RESULTS: The percentage of people with dementia who were very satisfied with the programme increased significantly over time (p = 0.05). The majority of carers reported that they felt less burdened after three months of participation in MCSP (48.1% much less; 35.4% a little less). After six months, this percentage increased significantly to 91% (p = 0.04, 57.7% much less; 33.3% little less). Focus group analysis showed that people with dementia and carers in all countries/centres improved their ability to maintain emotional balance. CONCLUSIONS: The MCSP is highly appreciated by people with dementia and carers in all countries and it confirms the results of previous research into MCSP in the Netherlands. Our findings indicate that MCSP is a model that can help its users to increase their capacity to deal with the challenges caused by dementia and can promote emotional balance.

RESUMEN

Breast milk composition is influenced by habitual diet, yet little is known about the short-term effects of changes in maternal diet on breast milk macronutrient concentrations. Our aim was to determine the acute effect of increased consumption of sugar/fat on breast milk protein, lactose and lipids. Exclusively breastfeeding women (n = 9) were provided with a control, higher fat (+28 g fat) and higher sugar (+66 g sugar) diet over three separate days at least 1 week apart. Hourly breast milk samples were collected concurrently for the analysis of triglycerides, cholesterol, protein, and lactose concentrations. Breast milk triglycerides increased significantly following both the higher fat and sugar diet with a greater response to the higher sugar compared to control diet (mean differences of 3.05 g/dL ± 0.39 and 13.8 g/dL ± 0.39 in higher fat and sugar diets, respectively [P < 0.001]). Breast milk cholesterol concentrations increased most in response to the higher sugar diet (0.07 g/dL ± 0.005) compared to the control (0.04 g/dL) and the higher fat diet (0.05 g/dL) P < 0.005. Breast milk triglyceride and lactose concentrations increased (P < 0.001, P = 0.006), whereas protein decreased (p = 0.05) in response to the higher fat diet compared to the control. Independent of diet, there were significant variations in breast milk composition over the day; triglycerides and cholesterol concentrations were higher at end of day (P < 0.001), whereas protein and lactose concentrations peaked at Hour 10 (of 12) (P < 0.001). In conclusion, controlled short-term feeding to increase daily sugar/fat consumption altered breast milk triglycerides, cholesterol, protein and lactose. The variations observed in breast milk protein and lactose across the 12 h period is suggestive of a circadian rhythm.

RESUMEN

n-6 Fatty acids have been shown to exert pro-adipogenic effects, whereas n-3 fatty acids work in opposition. Increasing intakes of linoleic acid (LA; n-6) v. α-linolenic acid (ALA; n-3) in Western diets has led to the hypothesis that consumption of this diet during pregnancy may be contributing to adverse offspring health. This study investigated the effects of feeding a maternal dietary LA:ALA ratio similar to that of the Western diet (9:1) compared with a proposed 'ideal' ratio (about 1:1·5), at two total fat levels (18 v. 36 % fat, w/w), on growth and lipogenic gene expression in the offspring. Female Wistar rats were assigned to one of the four experimental groups throughout gestation and lactation. Offspring were culled at 1 and 2 weeks of age for sample collection. Offspring of dams consuming a 36 % fat diet were approximately 20 % lighter than those exposed to an 18 % fat diet (P < 0·001). Male, but not female, liver weight at 1 week was approximately 13 % heavier and had increased glycogen (P < 0·05), in offspring exposed to high LA (P < 0·01). Hepatic expression of lipogenic genes suggested an increase in lipogenesis in male offspring exposed to a 36 % fat maternal diet and in female offspring exposed to a low-LA diet, via increases in the expression of fatty acid synthase and sterol regulatory element-binding protein. Sexually dimorphic responses to altered maternal diet appeared to persist until 2 weeks of age. In conclusion, whilst maternal total fat content predominantly affected offspring growth, fatty acid ratio and total fat content had sexually dimorphic effects on offspring liver weight and composition.

RESUMEN

Objectives: Until now little research has been done to answer the question of whether people with dementia experience stigma. No previous studies investigated possible differences between countries and cultures. Therefore, the aims of this study were to compare the experience of stigma (with social isolation, social rejection and internalised shame as components) among people with dementia and mild cognitive impairment (MCI) (n = 180) in Italy (n = 79), Poland (n = 47) and the United Kingdom (UK) (n = 54); and to investigate possible relationships with demographical and clinical outcomes.Methods: A one group multinational cross-sectional design was used. Stigma was measured with the Stigma Impact Scale (SIS), quality of life aspects with Dementia Quality of Life scale (DQOL) and Quality of Life Alzheimer's Disease scale (QOL-AD), social support with Duke Social Support Index (DSSI), cognitive functioning with Global Deterioration Scale (GDS).Results: The level of stigmatisation (SIS) among study participants varied from 2 to 65 (median = 33.5; Q1 = 27; Q3 = 41). People with dementia in the UK experienced a higher level of stigmatisation than people in Italy and Poland. The experienced stigmatisation negatively correlated with social support (DSSI; rho = -0.42, p = 0.000) and quality of life (QOL-AD; rho = -0.39, p = 0.000). People who experienced a higher level of stigmatisation scored higher in negative mood DQOL subscale (rho = 0.28, p = 0.0002).Conclusion: There is a strong need for research into the individual experience of people with dementia across the world. This could help in providing support and care services that match their experience, needs, preferences; and in designing well informed awareness campaigns based on their voice.

RESUMEN

ABSTRACTBackground:The "pathway to care" concept offers a helpful framework for preparing national dementia plans and strategies and provides a structure to explore the availability and accessibility of timely and effective care for people with dementia and support for their informal carers. Within the framework of the JPND-MEETINGDEM implementation project the pathways to regular day-care activities and the Meeting Centers Support Programme (MCSP), an innovative combined support form for people with dementia and carers, was explored. METHODS: An exploratory, descriptive, qualitative, cross-country design was applied to investigate the pathways to day care in several regions in four European countries (Italy, Poland, United Kingdom, and the Netherlands). RESULTS: Before implementation of MCSP, of the four countries the United Kingdom had the most structured pathway to post-diagnostic support for people with dementia. MCSP introduction had a positive impact on the pathways to day-care activities in all countries. MCSP filled an important gap in post-diagnostic care, increasing the accessibility to support for both people with dementia and carers. Key elements such as program of activities, target group, and collaboration between healthcare and social services were recognized as success factors. CONCLUSIONS: This study shows that MCSP fills (part of) the gap between diagnosis and residential care and can therefore be seen as a pillar of post-diagnostic care and support. Further dissemination of Meeting Centers in Europe may have a multiple impact on the structure of dementia services in European countries and the pathways to day care for people with dementia and their carer(s).

RESUMEN

Nutrition during pregnancy can impact on the susceptibility of the offspring to CVD. Postnatal consumption of trans-fatty acids (TFA), associated with partially hydrogenated vegetable oil (PHVO), increases the risk of atherosclerosis, whereas evidence for those TFA associated with ruminant-derived dairy products and meat remain equivocal. In this study, we investigate the impact of maternal consumption of dietary PHVO (P) and ruminant milk fat (R) on the development of atherosclerosis in their offspring, using the transgenic apoE*3 Leiden mouse. Dams were fed either chow (C) or one of three high-fat diets: a diet reflecting the SFA content of a 'Western' diet (W) or one enriched with either P or R. Diets were fed during either pregnancy alone or pregnancy and lactation. Weaned offspring were then transferred to an atherogenic diet for 12 weeks. Atherosclerosis was assessed as lipid staining in cross-sections of the aorta. There was a significant effect of maternal diet during pregnancy on development of atherosclerosis (P=0·013) in the offspring with those born of mothers fed R or P during pregnancy displaying smaller lesions that those fed C or W. This was not associated with changes in total or lipoprotein cholesterol. Continuing to feed P during lactation increased atherosclerosis compared with that seen in offspring of dams fed P only during pregnancy (P<0·001). No such effect was seen in those from mothers fed R (P=0·596) or W (P=901). We conclude that dietary TFA have differing effects on cardiovascular risk at different stages of the lifecycle.
