Characteristics of the home food environment that mediate immediate and sustained increases in child fruit and vegetable consumption: mediation analysis from the Healthy Habits cluster randomised controlled trial

BACKGROUND: The home food environment can influence the development of dietary behaviours in children, and interventions that modify characteristics of the home food environment have been shown to increase children’s fruit and vegetable consumption. However to date, interventions to increase children’s fruit and vegetable consumption have generally produced only modest effects. Mediation analysis can help in the design of more efficient and effective interventions by identifying the mechanisms through which interventions have an effect. This study aimed to identify characteristics of the home food environment that mediated immediate and sustained increases in children’s fruit and vegetable consumption following the 4-week Healthy Habits telephone-based parent intervention. METHOD: Analysis was conducted using 2-month (immediate) and 12-month (sustained) follow-up data from a cluster randomised control trial of a home food environment intervention to increase the fruit and vegetable consumption of preschool children. Using recursive path analysis, a series of mediation models were created to investigate the direct and indirect effects of immediate and sustained changes to characteristics of the home food environment (fruit and vegetable availability, accessibility, parent intake, parent providing behaviour, role-modelling, mealtime eating practices, child feeding strategies, and pressure to eat), on the change in children’s fruit and vegetable consumption. RESULTS: Of the 394 participants in the randomised trial, 357 and 329 completed the 2- and 12-month follow-up respectively. The final mediation model suggests that the effect of the intervention on the children’s fruit and vegetable consumption was mediated by parent fruit and vegetable intake and parent provision of these foods at both 2- and 12-month follow-up. CONCLUSION: Analysis of data from the Healthy Habits trial suggests that two environmental variables (parental intake and parent providing) mediate the immediate and sustained effect of the intervention, and it is recommended these variables be targeted in subsequent home food environment interventions to bring about immediate and sustained changes in child fruit and vegetable intake.

Weighing as a stand-alone intervention does not reduce excessive gestational weight gain compared to routine antenatal care:a systematic review and meta-analysis of randomised controlled trials

Background: Excessive gestational weight gain is associated with short and long-term adverse maternal and infant health outcomes, independent of pre-pregnancy body mass index. Weighing pregnant women as a stand-alone intervention during antenatal visits is suggested to reduce pregnancy weight gain. In the absence of effective interventions to reduce excessive gestational gain within the real world setting, this study aims to test if routine weighing as a stand-alone intervention can reduce total pregnancy weight gain and, in particular, excessive gestational weight gain. Methods: A systematic review and meta-analysis of randomised controlled trials (RCTs) was conducted between November 2014 and January 2016, and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Seven databases were searched. A priori eligibility criteria were applied to published literature by at least two independent reviewers. Studies considered methodologically rigorous, as per the Academy of Nutrition and Dietetics Quality Criteria Checklist for Primary Research, were included. Meta-analysis was conducted using fixed-effects models. Results: A total of 5223 (non-duplicated) records were screened, resulting in two RCTs that were pooled for meta-analysis (n = 1068 randomised participants; n = 538 intervention, n = 534 control). No difference in total weight gain per week was observed between intervention and control groups (weighted mean difference (WMD) -0.00 kg/week, 95% confidence interval (CI) -0.03 to 0.02). There was also no reduction in excessive gestational weight gain between intervention and control, according to pre-pregnancy body mass index (BMI). However, total weight gain was lower in underweight women (n = 23, BMI <18.5 kg/m2) in the intervention compared to control group (−0.12 kg/week, 95% CI −0.23 to −0.01). No significant differences were observed for other pregnancy, birth and infant outcomes. Conclusion: Weighing as a stand-alone intervention is not worse nor better at reducing excessive gestational weight gain than routine antenatal care

The effect of parity on longitudinal maternal hemodynamics

BACKGROUND: Parous women have a lower risk for pregnancy complications, such as preeclampsia (PE) or delivery of small for gestational age (SGA) neonates. However, parous women are a heterogeneous group of patients as they contain a low-risk cohort with previously uncomplicated pregnancies and a high-risk cohort with previous pregnancies complicated by PE and / or SGA. Previous studies examining the effect of parity on maternal hemodynamics, including cardiac output (CO) and peripheral vascular resistance (PVR), did not distinguish between parous women with and without a history of PE or SGA and reported contradictory results.OBJECTIVES: To compare maternal hemodynamics, in nulliparous women and in parous women with and without previous PE and / or SGA.STUDY DESIGN: This was a prospective, longitudinal study of maternal hemodynamics, assessed by a bioreactance method, measured at 11+0-13+6, 19+0-24+0, 30+0-34+0 and 35+0-37+0 weeks' gestation in three groups of women. Group 1 was composed of parous women without history of PE and / or SGA (n=632), Group 2 was of nulliparous women (n=829) and Group 3 was composed of parous women with history of PE and / or SGA (n=113). Multilevel linear mixed-effects model was performed to compare the repeated measures of hemodynamic variables controlling for maternal characteristics, medical history, and development of PE or SGA in the current pregnancy.RESULTS: In groups 1 and 2, CO increased with gestational age to a peak at 32 weeks and PVR showed a reversed pattern with its nadir at 32 weeks; in group 1, compared to group 2, there was better cardiac adaptation, reflected in higher CO and lower PVR. In group 3 there was a hyperdynamic profile of higher CO and lower PVR at first trimester followed by an earlier sharp decline of CO and increase of PVR from mid-gestation. The incidence of PE and SGA was highest in group 3 and lowest in group1.CONCLUSION: There are parity-specific differences in maternal cardiac adaptation in pregnancy.</p

Factors, trends, and long-term outcomes for stroke patients returning to work:The South London Stroke Register

Background and purpose: There is limited information on factors, trends, and outcomes in return to work at different time-points post-stroke; this study aims to identify these in a multi-ethnic urban population. Methods: Patterns of return to work were identified in individuals in paid work prior to first-ever stroke in the population-based South London Stroke Register (SLSR) between 1995 and 2014. Multivariable logistic regression examined associations between patient characteristics and return to work at 1 year (1 y), 5 years (5 y) and 10 years (10 y) post-stroke. Results: Among 5609 patients, 940 (17%) were working prior to their stroke, of whom 177 (19%) were working 3 months post-stroke, declining to 172 (18%) at 1 y, 113 (12%) at 5 y, and 27 (3%) at 10 y. Factors associated with return to work within 1 y, after logistic regression, included functional independence (BI ≥ 19; p &lt; 0.01) and shorter length of stay (p &lt; 0.05). Younger age (p &lt; 0.01) was associated with return to work at 5 y and 10 y post-stroke. Non-manual occupation (p &lt; 0.05) was associated with return to work at 10 y post-stroke. Return to work within 1 y increased the likelihood of working at 5 y (OR: 13.68; 95% CI 5.03–37.24) and 10 y (9.07; 2.07–39.8). Of those who were independent at follow-up (BI ≥ 19), 48% were working at 1 y, 42% at 5 y, and 28% at 10 y. Lower rates of anxiety and depression and higher self-rated health were associated with return to work at 1 y (p &lt; 0.01). Conclusion: Although functionally independent stroke survivors are more likely to return to work long-term, a large proportion do not return to work despite functional independence. Return to work post-stroke is associated with improved long-term psychological outcomes and quality of life.</p

Costs of UK community care for individuals with recessive dystrophic epidermolysis bullosa:Findings of the Prospective Epidermolysis Bullosa Longitudinal Evaluation Study

Background Recessive dystrophic epidermolysis bullosa (RDEB) is a rare inherited skin fragility disorder requiring multidisciplinary management. Information regarding costs of current standard treatment is scant. Objectives As part of a longitudinal natural history study, we explored the community care costs of UK patients with different forms of RDEB. Methods Fifty-nine individuals with RDEB provided detailed information on multiple facets of RDEB including disease severity scores (iscorEB, BEBS) and patient reported outcomes (quality of life evaluation in epidermolysis bullosa, iscorEB patient questionnaire). Costs data included time spent doing dressings, frequency of dressing changes, details of materials used, and paid and unpaid care. Results Overall costs of dressing materials and associated care were high in RDEB. Median annual costs across all subtypes for those using dressings (n = 51) were over £26 000. For severe RDEB (RDEB-S), median costs were almost £90 000 per annum, with a median of 18 h per week spent on dressing changes. Half of working-age adults with RDEB were unemployed and 39time or part-time paid employment, adding to indirect costs and the financial burden from RDEB on families and society. Conclusions The findings demonstrate the high costs of care of RDEB, particularly for RDEB-S. The current expense supports the drive to develop new therapies which accelerate wound healing and diminish total wound burden, thereby reducing costs of dressings and care. While costly to bring to market, these might ultimately reduce the overall cost of treatment and also the impact on individuals living with this rare disease. The data also highlight the need for adequate reimbursement for EB care which can place significant financial strain on families.<br/

Pain in recessive dystrophic epidermolysis bullosa (RDEB): findings of the Prospective Epidermolysis Bullosa Longitudinal Evaluation Study (PEBLES)

BackgroundPain is common in the genetic skin fragility disorder epidermolysis bullosa (EB), from skin and mucosal injury and inflammation as well as extra-mucocutaneous sites. Individuals living with EB have identified pain as a priority for better treatments.ObjectivesThe Prospective EB Longitudinal Evaluation Study (PEBLES) is a prospective register study exploring the natural history of RDEB across all ages from birth to death. Here, we investigated the characteristics and treatment of pain in different RDEB subtypes.MethodsInformation was collected from individuals with different RDEB subtypes over an 8-year period. Data included visual analogue scale (VAS) ratings of background and procedural pain, its location, intensity and impact on sleep, as well as pain medication. Disease severity scores and quality of life measures were correlated to pain scores.ResultsSixty-one participants (13 children, 48 adults) completed a total of 361 reviews. Pain was common, experienced by 93% of participants at index review, with 80% suffering both background and procedural pain. Across all RDEB patients, the median VAS for background pain was 40 (out of 100) [interquartile range 20,60] and for those having regular dressing changes, median procedural pain was 52 [40,80]. Severe (RDEB-S) and pruriginosa (RDEB-Pru) groups had the greatest increase in procedural compared to background pain of 20 and 22 VAS points, respectively. Correlations between disease severity and quality of life impairment were observed across most groups, particularly RDEB-S. Over half of those studied experienced pain frequently or constantly, and in one third pain disturbed sleep at least 4 nights per week. Skin was the commonest source of pain in all subtypes except inversa RDEB where the mouth was the main site. Despite frequent and severe pain, one third of participants used no medication for pain and, in those that did, pain levels remained high suggesting ineffectiveness of current pain management approaches and a significant unmet need in RDEB.ConclusionThe frequency, severity, and impact of pain in all RDEB patients is significant, particularly in RDEB-S and RDEB-Pru. Our findings highlight that current RDEB pain management is poorly effective and that further research is needed to address this symptom.<br/

Involved-field radiotherapy for patients with mantle cell lymphoma

Introduction: Retrospective analysis was performed at a single institution to assess the responsiveness of mantle cell lymphoma (MCL) to involved-field radiotherapy (IFRT). Methods: All patients treated with IFRT to at least one site of MCL between 1998 and 2012 were included. There were 25 patients who received radiotherapy to 60 disease sites. Primary endpoint was overall response rate (ORR) infield for the first site of MCL treated per patient. Predictors of ORR were analysed for the primary endpoint. Time to local progression (TLP) infield and progression-free survival were calculated from the start of the first treatment course. Analysis of all sites collectively was also undertaken. Survival analysis was conducted by the Kaplan-Meier method. Results: ORR rate was 84% for the first site treated per patient. Complete response and partial response rates were 68% and 16% respectively. Median TLP following radiotherapy to the first site was not reached. Infield control rate was 91% at 12 months (95% confidence interval 69-97%). When analysis was performed on all 60 sites, ORR was 85%. Symptomatic improvement occurred after IFRT to 93% of all sites. Systemic progression outside the radiotherapy field was the predominant form of failure following IFRT. Conclusion: Radiotherapy generally induced a clinical response at all levels of dose administered, ranging from 3 to 36Gy. However, increased durability of local control was suggested with higher doses. Radiotherapy is an effective treatment for palliation of MCL with objective and symptomatic responses seen over a range of radiotherapy doses
