Outcomes for gastrostomy‐fed children and their parents : qualitative findings from the ‘Your Tube’ study

Aim To identify child and parent outcomes relevant to having a gastrostomy, and to specify outcomes believed to be particularly salient to type of diet (formula vs blended food). Method Twenty parents, two children (both 12y), and 41 professionals (dietitians [n=10]; nurses [n=12]; paediatricians [n=12]; speech and language therapists [n=7)]) were recruited. Parents and children were interviewed; professionals participated in focus groups. Children (2–18y) represented included those on formula (n=11), blended-food (n=7), and mixed (n=2) diets. All had been tube-fed for at least 6 months. Neurological, genetic, and metabolic conditions were represented. Results Participants identified a range of children’s outcomes relevant to a gastrostomy, including physical health, gastrointestinal symptoms, sleep, and time spent feeding. The children described experiences of exclusion caused by being tube-fed. Time, sleep, and emotional health were regarded as most salient to understanding parents’ gastrostomy outcomes. Participants believed type of diet would most likely effect gastrointestinal symptoms, time spent feeding, sleep, and physical health. Interpretation Findings indicate a number of refinements to, and allow further specification of, the current ‘initial’ core outcome set for tube-fed children. Findings also have implications for choice of outcomes measures. Further qualitative research with children and young people is needed

Safety, resource use and nutritional content of home-blended diets in children who are gastrostomy fed : findings from 'YourTube' - a prospective cohort study

OBJECTIVE: To assess the risks, benefits and resource implications of using home-blended food in children with gastrostomy tubes compared with currently recommended formula feeds. DESIGN: This is a cohort study. Data were collected at months 0, 12 and 18 from parents and clinicians using standardised measures. SETTING: 32 sites across England: 28 National Health Service trusts and 4 children's hospices. PATIENTS: Children aged 6 months-18 years who were gastrostomy fed. MAIN OUTCOME MEASURE: The main outcome measure was the PedsQL Gastrointestinal Symptoms Scales score. Secondary outcomes included quality of life, sleep (child, parent), dietary intake, anthropometry, healthcare usage, safety outcomes and resource use. RESULTS: 180 children and families completed the baseline data collection, with 134 (74%) and 105 (58%) providing follow-up data at 12 and 18 months. There were fewer gastrointestinal (GI) symptoms at all time points in the home-blended diet group, but there was no difference in change over time within or between the groups. The nutritional intake of those on a home-blended diet had higher calories per kilogram and fibre, and both home-blended and formula-fed children have values above the dietary reference values for most micronutrients. Safety outcomes were similar between groups and over time. The total costs to the statutory sector were higher among children who were formula fed, but the costs of purchasing special equipment for home-blended food and the total time spent on childcare were higher for families with home-blended diet. CONCLUSIONS: Children who are gastrostomy fed a home-blended diet have similar safety profile, adequate nutritional intake and lower burden of GI symptoms than formula-fed children.

Maternal iodine status, intrauterine growth, birth outcomes and congenital anomalies in a UK birth cohort.

BACKGROUND: Severe iodine insufficiency in pregnancy has significant consequences, but there is inadequate evidence to indicate what constitutes mild or moderate insufficiency, in terms of observed detrimental effects on pregnancy or birth outcomes. A limited number of studies have examined iodine status and birth outcomes, finding inconsistent evidence for specific outcomes. METHODS: Maternal iodine status was estimated from spot urine samples collected at 26-28 weeks' gestation from 6971 mothers in the Born in Bradford birth cohort. Associations with outcomes were examined for both urinary iodine concentration (UIC) and iodine-to-creatinine ratio (I:Cr). Outcomes assessed included customised birthweight (primary outcome), birthweight, small for gestational age (SGA), low birthweight, head circumference and APGAR score. RESULTS: There was a small positive association between I:Cr and birthweight in adjusted analyses. For a typical participant, the predicted birthweight centile at the 25th percentile of I:Cr (59 μg/g) was 2.7 percentage points lower than that at the 75th percentile of I:Cr (121 μg/g) (99% confidence interval (CI) 0.8 to 4.6), birthweight was predicted to be 41 g lower (99% CI 13 to 69) and the predicted probability of SGA was 1.9 percentage points higher (99% CI 0.0 to 3.7). There was no evidence of associations using UIC or other birth outcomes, including stillbirth, preterm birth, ultrasound growth measures or congenital anomalies. CONCLUSION: Lower maternal iodine status was associated with lower birthweight and greater probability of SGA. Whilst small, the effect size for lower iodine on birthweight is comparable to environmental tobacco smoke exposure. Iodine insufficiency is avoidable, and strategies to avoid deficiency in women of reproductive age should be considered. TRIAL REGISTRATION: ClinicalTrials.gov NCT03552341.

Maternal iodine status in a multi-ethnic UK birth cohort: associations with autism spectrum disorder.

BACKGROUND: Maternal iodine requirements increase during pregnancy to supply thyroid hormones essential for fetal brain development. Maternal iodine deficiency can lead to hypothyroxinemia, a reduced fetal supply of thyroid hormones which, in the first trimester, has been linked to an increased risk of autism spectrum disorder (ASD) in the child. No study to date has explored the direct link between maternal iodine deficiency and diagnosis of ASD in offspring. METHODS: Urinary iodine concentrations (UIC) and iodine/creatinine ratios (I:Cr) were measured in 6955 mothers at 26-28 weeks gestation participating in the Born in Bradford (BiB) cohort. Maternal iodine status was examined in relation to the probability of a Read (CTV3) code for autism being present in a child's primary care records through a series of logistic regression models with restricted cubic splines. RESULTS: Median (inter-quartile range) UIC was 76 μg/L (46, 120) and I:Cr was 83 μg/g (59, 121) indicating a deficient population according to WHO guidelines. Ninety two children (1·3%) in our cohort had received a diagnosis of ASD by the census date. Overall, there was no evidence to support an association between I:Cr or UIC and ASD risk in children aged 8-12 years (p = 0·3). CONCLUSIONS: There was no evidence of an increased clinical ASD risk in children born to mothers with mild-to-moderate iodine deficiency at 26 weeks gestation. Alternative functional biomarkers of exposure and a wider range of conditions may provide further insight

Diet in three towns in England

Attempts to relate the geographical distribution of diseases in England to dietary intakes have been limited by the lack of age- and sex-specific dietary information. The diet of middle-aged (35-54 years) men and women in Ipswich, Wakefield and Stoke-on-Trent was studied. These towns were chosen because of their differences in socioeconomic status and geographical location within England. They also have differences in disease rates including heart disease, gallstones and stomach cancer. A 24-hour dietary record in household measures and a questionnaire were obtained from about 400 men and 400 women in each town, giving a response rate of 85 per cent. The fieldwork was carried out over one year. A number of characteristics of the people in the towns were examined. There were differences in height for men and body mass index for women, activity, alcohol intake and amount of tobacco smoked. Food and nutrient intakes differed more among the men than the women. Total fibre, vitamin C and B carotene intakes of women were significantly different between towns. For men, proximate nutrient intakes were highest in Stoke whereas vitamin C, vitamin A, B carotene and retinol levels were highest in Ipswich. Generally, Wakefield had the lowest nutrient values. The main nutritionally related potential risk factors for the diseases considered were not supported by the results of the study. Very little in the present diet appears to explain present differences in rates of disease between towns, other factors must be in operation.</p

My Meal Mate Smartphone Application for Weight Loss: Pilot Randomized Controlled Trial

Background: There is growing interest in the use of information communication technologies to treat obesity. An intervention delivered by smartphone could be a convenient, potentially cost-effective, and wide-reaching weight management strategy. Although there have been studies of texting-based interventions and smartphone applications (apps) used as adjuncts to other treatments, there are currently no randomized controlled trials (RCT) of a stand-alone smartphone application for weight loss that focuses primarily on self-monitoring of diet and physical activity. Objective: The aim of this pilot study was to collect acceptability and feasibility outcomes of a self-monitoring weight management intervention delivered by a smartphone app, compared to a website and paper diary. Methods: A sample of 128 overweight volunteers were randomized to receive a weight management intervention delivered by smartphone app, website, or paper diary. The smartphone app intervention, My Meal Mate (MMM), was developed by the research team using an evidence-based behavioral approach. The app incorporates goal setting, self-monitoring of diet and activity, and feedback via weekly text message. The website group used an existing commercially available slimming website from a company called Weight Loss Resources who also provided the paper diaries. The comparator groups delivered a similar self-monitoring intervention to the app, but by different modes of delivery. Participants were recruited by email, intranet, newsletters, and posters from large local employers. Trial duration was 6 months. The intervention and comparator groups were self-directed with no ongoing human input from the research team. The only face-to-face components were at baseline enrollment and brief follow-up sessions at 6 weeks and 6 months to take anthropometric measures and administer questionnaires. Results: Trial retention was 40/43 (93%) in the smartphone group, 19/42 (55%) in the website group, and 20/43 (53%) in the diary group at 6 months. Adherence was statistically significantly higher in the smartphone group with a mean of 92 days (SD 67) of dietary recording compared with 35 days (SD 44) in the website group and 29 days (SD 39) in the diary group (P<.001). Self-monitoring declined over time in all groups. In an intention-to-treat analysis using baseline observation carried forward for missing data, mean weight change at 6 months was -4.6 kg (95% CI –6.2 to –3.0) in the smartphone app group, –2.9 kg (95% CI –4.7 to –1.1) in the diary group, and –1.3 kg (95% CI –2.7 to 0.1) in the website group. BMI change at 6 months was –1.6 kg/m2 (95% CI –2.2 to –1.1) in the smartphone group, –1.0 kg/m2 (95% CI –1.6 to –0.4) in the diary group, and –0.5 kg/m2 (95% CI –0.9 to 0.0) in the website group. Change in body fat was –1.3% (95% CI –1.7 to –0.8) in the smartphone group, –0.9% (95% CI –1.5 to –0.4) in the diary group, and –0.5% (95% CI –0.9 to 0.0) in the website group. Conclusions: The MMM app is an acceptable and feasible weight loss intervention and a full RCT of this approach is warranted
