益生元与肠道粘膜免疫及婴幼儿过敏性疾病的研究进展

早期预防过敏性疾病对于阻断过敏进程,提高儿童生活质量非常重要。近期较多研究显示,益生元可以模拟母乳中低聚糖,通过多种途径参与肠道粘膜免疫,如影响肠道菌群的种类及数量、促进结肠内短链脂肪酸产生等,从而对过敏性疾病的发生产生影响。虽然对于益生元调节免疫及预防过敏的结论尚不完全一致,但越来越多的证据显示益生元可能是预防过敏性疾病重要措施之一。     

Developmental Progression of Motor Skills in Children Prenatally Exposed to Cocaine

This study tested the motor development of 73 infants who were prenatally exposed to cocaine using the Peabody Developmental Motor Scales at 6, 12, 18, and 24 months of age. Repeated measures MANOVA found a main effect for age with scores decreasing as children increased in age. The significant interactive effect between age and skill type indicated that fine motor quotient scores decreased more than the comparable gross motor scores. T-tests showed significant differences between the two skill types: fine motor skills were higher at the first two testing periods and lower at the last two periods. This article discusses the nature of the delays at specified age periods and the implications for future assessment and programming.     

A pilot study on early home-based intervention through an intelligent baby gym (CareToy) in preterm infants

BackgroundCareToy is an intelligent system, inspired by baby gyms, aimed to provide an intensive, individualized, home-based and family-centred early intervention (EI) program.AimsA pilot study was carried out to explore the feasibility of CareToy intervention in preterm infants, aged 3–9 months of corrected age.MethodsTwenty low-risk preterm infants, without brain lesion or other clinical complications (14 allocated to CareToy intervention and 6 to Standard Care) were recruited. The Infant Motor Profile (IMP) was predefined as the primary outcome measure and Alberta Infant Motor Scale and Teller Acuity Cards as secondary measures. Moreover, 202 pre-programmed training scenarios were developed and instructions for the management of CareToy intervention were defined as general guidelines.Outcomes and resultsAll infants received 4 weeks of their allocated intervention and were evaluated with the selected tests before and immediately after the 4 weeks. The mean difference changes in IMP total score and Teller Acuity Cards over the intervention period were higher in the CareToy group than in the Standard Care group.Conclusions and implicationsCareToy seems a feasible device for providing EI. An adequately powered randomized clinical trial is warranted.     

A Comparison of Recruitment Methods for an mHealth Intervention Targeting Mothers: Lessons from the Growing Healthy Program

BackgroundMobile health (mHealth) programs hold great promise for increasing the reach of public health interventions. However, mHealth is a relatively new field of research, presenting unique challenges for researchers. A key challenge is understanding the relative effectiveness and cost of various methods of recruitment to mHealth programs.ObjectiveThe objectives of this study were to (1) compare the effectiveness of various methods of recruitment to an mHealth intervention targeting healthy infant feeding practices, and (2) explore factors influencing practitioner referral to the intervention.MethodsThe Growing healthy study used a quasi-experimental design with an mHealth intervention group and a concurrent nonrandomized comparison group. Eligibility criteria included: expectant parents (>30 weeks of gestation) or parents with an infant <3 months old, ability to read and understand English, own a mobile phone, ≥18 years old, and living in Australia. Recruitment to the mHealth program consisted of: (1) practitioner-led recruitment through Maternal and Child Health nurses, midwives, and nurses in general practice; (2) face-to-face recruitment by researchers; and (3) online recruitment. Participants’ baseline surveys provided information regarding how participants heard about the study, and their sociodemographic details. Costs per participant recruited were calculated by taking into account direct advertising costs and researcher time/travel costs. Practitioner feedback relating to the recruitment process was obtained through a follow-up survey and qualitative interviews.ResultsA total of 300 participants were recruited to the mHealth intervention. The cost per participant recruited was lowest for online recruitment (AUD $14) and highest for practice nurse recruitment (AUD $586). Just over half of the intervention group (50.3%, 151/300) were recruited online over a 22-week period compared to practitioner recruitment (29.3%, 88/300 over 46 weeks) and face-to-face recruitment by researchers (7.3%, 22/300 over 18 weeks). No significant differences were observed in participant sociodemographic characteristics between recruitment methods, with the exception that practitioner/face-to-face recruitment resulted in a higher proportion of first-time parents (68% versus 48%, P=.002). Less than half of the practitioners surveyed reported referring to the program often or most of the time. Key barriers to practitioner referral included lack of time, difficulty remembering to refer, staff changes, lack of parental engagement, and practitioner difficulty in accessing the app.ConclusionsOnline recruitment using parenting-related Facebook pages was the most cost effective and timely method of recruitment to an mHealth intervention targeting parents of young infants. Consideration needs to be given to addressing practitioner barriers to referral, to further explore if this can be a viable method of recruitment.
