Abstract Objective: To determine whether the ‘Read for Nutrition’ program would increase liking and consumption of broccoli (a target vegetable) in preschool children and test acceptability and practicality of the program. Design: Pilot pre-post intervention study, where childcare teachers received training and coaching followed by reading the book “Monsters Don’t Eat Broccoli” multiple times with the children during a three-week intervention Setting: Five classrooms of Educare (blinded for peer review) in 2018. Participants: Sixty-nine (11 to 16 children per classroom) preschool-aged children and sixteen teachers (minimum, three per classroom). Results: Average total consumption of broccoli increased 35% (0.14 ounces or 0.05th cup) after the ‘Read for Nutrition’ program (t=2.66; p= .01; 95% CIs [0.035, 0.246]) for all children. Proportional consumption increased for children who received ≥ five exposures to the book (t 46 =2.77; p= .008). Exposures to the book predicted proportional consumption (β=.365; p=.002). Liking of broccoli increased (W 69 =2.2, p=.03) as well. Teachers rated the program as acceptable, practical, and enjoyable to children and to themselves. Conclusions: Programs such as ‘Read for Nutrition’ have the potential to improve children’s vegetable liking and consumption in ECE settings with only book readings and no exposure to a real vegetable.

Intervention Efficacy

BACKGROUND Interventions using activity trackers and smartphone apps have demonstrated their ability to increase physical activity in children and adults. However, they have not been tested in entire families. Further, few family-centred interventions have actively involved both parents, and assessed intervention efficacy separately for children, mothers and fathers. OBJECTIVE This study aimed to examine the short-term efficacy of an activity tracker and app intervention to increase physical activity in the entire family (children, mothers and fathers). METHODS This was a pilot single-arm intervention study with pre-post measures. Between 2017-2018, 40 families (58 children aged 6-10 years, 39 mothers, 33 fathers) participated in the 6-week Step it Up Family program in Queensland, Australia. Using commercial activity trackers combined with apps (Garmin Vivofit Jr for children, Vivofit 3 for adults), the intervention included individual and family-level goal-setting, self-monitoring, performance feedback, family step challenges, family social support and modelling, weekly motivational text messages, and an introductory session delivered face-to-face or via telephone. Parent surveys were used to assess intervention efficacy measured as pre-post intervention changes in moderate-to-vigorous physical activity (MVPA) in children, mothers and fathers. RESULTS Thirty-eight families completed the post intervention survey (95% retention). At post intervention, MVPA had increased in children by 58 min/day (boys: 54 min/day, girls: 62 min/day; all P < .001). In mothers, MVPA increased by 27 min/day (P < .001), and in fathers, it increased by 31 min/day (P < .001). Furthermore, the percentage of children meeting Australia’s physical activity guidelines for children (≥60 MVPA min/day) increased from 34% to 89% (P < .001). The percentage of mothers and fathers meeting Australia’s physical activity guidelines for adults (≥150 MVPA min/week) increased from 8% to 57% (P < .001) in mothers, and from 21% to 68% (P < .001) in fathers. CONCLUSIONS Findings suggest that an activity tracker and app intervention is an efficacious approach to increasing physical activity in entire families to meet national physical activity guidelines. The Step it Up Family program warrants further testing in a larger, randomised controlled trial to determine its long-term impact. CLINICALTRIAL No trial registration as this is not an RCT. It is a pilot single-arm intervention study

Objectives: To evaluate the effectiveness of needle-free connectors to maintain Central Venous Catheter—CVC patency. Background: Loss of patency is a common complication associated with CVC. For patients, this can be stressful and painful, and can result in a delay in infusion therapy. Pressure-activated anti-reflux needle-free connectors are one of the most modern devices; however, no studies have compared this connector with the open-system three-way stopcock in terms of the incidence of CVC occlusion. Methods: This study is a prospective before and after intervention study. From March to August 2018, an observation phase was conducted with the three-way stopcock as the standard central venous catheter hub and closure system (phase 1). After implementation of needle-free connectors (phase 2), post-intervention observations were made from September 2019 to January 2020 (phase 3). Results: Of 199 CVCs analyzed, 41.2% (40/97) occluded in at least one lumen in the first phase, and 13.7% (14/102) occluded after introducing the technological device, absolute risk reduction 27.5% (95% confidence interval 15.6%–39.4%). The lumens supported by needle-free connectors showed a higher probability of maintaining patency compared with three-way stopcocks. No differences were observed in the rate of infection. Conclusions: Pressure-activated anti-reflux needle-free connectors are effective and safe devices suitable for the management of vascular access in cardiac patient care. Staff training, even on apparently simple devices, is essential to avoid the risk of infection.

Background and Objectives: Globally, 2.5 million newborns die within the first month of life annually. The majority of deaths occur in low- and middle-income countries (LMICs), and many of these deaths happen at home. The study assessed if the Care Companion Program (CCP) an in-hospital, skills-based training given to families improves post-discharge maternal and neonatal health outcomes. Methods: This quasi-experimental pre-post intervention study design compared self-reported behavior and health outcomes among families before and after the CCP intervention. Intention to treat analysis included families regardless of their exposure to the intervention. Mixed effects logistic regression model, adjusted for confounders, was fit for all observations. Effects were expressed as Relative Risks (RR) with 95% Confidence Intervals (CI). Results: At 2-weeks post-delivery, telephone surveys were conducted in the pre (n = 3510) and post-intervention (n = 1474) groups from 11 district hospitals in the states of Karnataka and Punjab. The practice of dry cord care improved significantly by 4%, (RR = 1.04, 95%CI [1.04,1.06]) and skin to skin care by 78% (RR=1.78, 95%CI [1.37,2.27]) in the post-intervention group as compared to pre-intervention group. Furthermore, newborn complications reduced by 16% (RR=0.84, 95%CI [0.76,0.91]), mother complications by 12% (RR=0.88, 95%CI [0.79,0.97]) and newborn readmissions by 56% (RR=0.44, 95%CI [0.31,0.61]). Outpatient visits increased by 27% (RR=1.27, 95%CI [1.10,1.46]). However, outcomes of breastfeeding, mothers diet, hand-hygiene, and process indicator of being instructed on warning signs were not different. Conclusion: Postnatal care should incorporate pre-discharge multi-pronged training of families to improve essential maternal and newborn care practices. The CCP model runs on a public-private partnership and is integrated into existing health systems. Our findings demonstrate that it is possible to improve outcomes through a family-centered approach in India. The CCP model can be integrated into formalised hospital processes to relieve overburdened healthcare systems in LMIC settings.

Methodological Refinement

Methodologists have urged researchers who use mixed methods to justify their methodological choices and provide greater clarity about the philosophical underpinnings and implications of their approaches. This article outlines the reasoning process undertaken in an endeavor to develop philosophical clarity for an applied, interdisciplinary, mixed methods research project about the communication of scientific evidence in the legal system. I used Greene’s domains of methodology for social inquiry as a framework for addressing reflexive questions about assumptions. Flowing from the domains of values and philosophies, the logic of inquiry was developed before the implications for the integration of findings and reporting of research were outlined. Early engagement in reflexive questioning provided a foundation for methodological refinement throughout the ongoing research journey.

SUMMARYThe goal of this study was to determine the reduction in risk of infection by viruses with the use of an alcohol-based hand sanitizer, used in addition to routine hand washing, in family members in households. A quantitative microbial risk model was used to determine the probability of infection from the concentration of virus on the hands. The model incorporated variation in hand size, frequency of touching orifices (nose, mouth, eyes), and percent transfer to the site of infection, as well as, dose-response for each virus. Data on the occurrence of virus on household members' hands from an intervention study using MS-2 coliphage was used to determine the reduction of viruses on the hands pre- and post-intervention. It was found that the risk of rhinovirus, rotavirus or norovirus infection after the intervention was reduced by 47–98% depending upon the initial concentration of virus on the hands.

Background: UK Government recommendations for dietary fibre intakes have recently increased to 30 g per day, well below current population intakes. Aim: This study aimed to explore whether the target for dietary fibre intake could be achieved and the effects on markers of cardiometabolic health. Methods: In this 4-week high-fibre intervention study, 15 participants were instructed to achieve dietary fibre intakes of 30 g/day. Results: Dietary fibre intakes significantly increased post intervention (16.0 ± 8.1 g/day, p < 0.001). No significant changes in glucose and triglyceride concentrations were observed and there was a significant increase in average body weight (0.7 ± 1.2 kg, p = 0.025). Conclusions: This study shows that achieving the new dietary fibre recommendations of 30g/day is achievable, in the short term, in a sample of British adults without any observed effect on health markers.
