BackgroundAbusive head trauma (AHT) is a preventable form of child abuse.ObjectiveThis project used a mixed method design to assess the feasibility of the Calm Baby Gently educational baby book intervention for promoting safe practices related to infant crying in an effort to prevent AHT.Participants and settingThree pediatric practices participated between June 2016 and January 2018, including 1045 caregivers who attended their infant’s 2-month well-child visit.MethodsPediatric providers gave the educational baby book to caregivers at the 1-month well-child visit. Caregivers completed a survey at the 2-month well-child visit on their use and satisfaction with the book and responses to infant crying. Thematic analysis of qualitative feedback was performed. Responses to infant crying were compared quantitatively between caregivers who had and had not read the book.ResultsOf the 819 caregivers (78%) who received the book, 92% (754) read it, and 51% (421) had another caregiver read it. Caregivers considered the book approachable, understandable, validating, and helpful for improving knowledge and skills related to infant crying. The book was rated more helpful by caregivers of younger age, male gender, and non-white race. Controlling for age, gender, and race, caregivers who read the book were more confident (p = 0.033) and had more knowledge on how to respond appropriately to infant crying (p = 0.019) than caregivers who had not read it.ConclusionsCalm Baby Gently is a feasible and well-received AHT prevention program. Randomized controlled trials are needed to better understand its impact on knowledge, behavior, and AHT rates.  相似文献

SUMMARY

When the symptoms of a possible sick building syndrome appeared in a library building more than twenty years ago, it was thought that the situation could be easily fixed. Instead, we are still managing a problem building although extensive work has been done and much progress has been made to moderate the physical reactions of staff and building users. Looking after the well being of our staff has been the primary motivation.  相似文献

在苯乙烯-丁二烯-苯乙烯三嵌段共聚物(SBS)中添加马来酸酐化聚丁二烯(MLPB)和胺化环氧丁二烯(LCP)可以适当提高胶粘剂的力学性能,其得到的最大拉伸强度分别为2.671MPa和8.652MPa。研究结果表明,温度以及添加胺化LCP和MLPB可以促进胶粘剂中互穿聚合物网络的形成,提高胶粘剂的强度。  相似文献

Extensive intestine resection may result in short bowel syndrome (SBS) which is difficult of manage. This study reports a rare SBS case in a 6-year-old boy following resection of total jujunoileum and right colon. Our experience in 4-years follow-up and literature reports on SBS is discussed. The purpose of this study was also to evaluate the nutritional absorptive capacity and intestinal adaptation. In the 15th postoperative month, barium x-ray study showed a significantly extended and enlarged duodenum and colon. The intestinal transit time was prolonged to 22 hours. The absorption rate of palmic acid, glycine and D-xylose had increased from 57%, 50% and 4% respectively in the 15th postoperative month, to 75%, 65% and 6% in the 2nd postoperative year. His absorptive capacity allowed him normal oral feeding and normal school life. Our data confirmed the reports of the colon as an energy-salvage organ, and suggested that it may have some capacity to absorb long-chain fatty acids and amino acids.  相似文献
