In this article, I describe the effects of home interventions on latching difficulty that persisted for 27 days for a mother–neonate dyad. The neonate manifested latching difficulty immediately after cesarean birth, and it became worse when nipple shields, bottles, and pacifiers were introduced. Manual expression and an electric pump were implemented when the neonate started losing weight, resulting in reduced frequency of breastfeeding directly at the breast. Additionally, the neonate continued to have latching difficulty after frenotomy. The use of home-based interventions supported ongoing educational opportunities for optimal latch, and I recommend that this type of health education be consistent among health professionals. 相似文献

目的 比较改良长U形空心椎弓根钉及配套锁定插销与传统长U形空心椎弓根钉的机械性能,验证其力学稳定性。方法 准备改良椎弓根钉及配套插销(观察组)与传统空心椎弓根钉(对照组)各10套,分别通过机械测定实验和有限元方法比较两组的屈服载荷、刚度等力学数据。结果 在机械性能单点弯曲静态测试和有限元分析中,观察组刚度、屈服载荷都较对照组提升,差异均有统计学意义(P0.05)。同时在动态疲劳测试中,观察组的疲劳寿命更长,差异有统计学意义(P0.05)。而有限元分析中,相同载荷情况下,观察组模型应力分布更均匀、弯曲性能更好。结论 改良长U形空心椎弓根钉及配套锁定插销应力分布均匀、安全性能好,值得进一步临床推广应用。 相似文献

Purpose
This paper presents an own proposal for the construction of a ball latch intended for use in prosthetic dentistry. Attention was paid to the existing commercial constructions of elements of the same type, indicating their advantages and disadvantages. Based on the analysis of the present solutions, own ones were proposed.Materials and methods
The following materials were chosen for the tests: pure titanium, 316?L?V steel, Ti15Mo2.8Nb obtained using powder metallurgy and through mechanical alloying, 10 and 20% of titanium carbide – obtained using powder metallurgy, as well as 10 and 20% of graphite – obtained using powder metallurgy. For the prepared materials, tribological tests were performed using a friction simulator in a ring/shield system.Results
Fairly extensive tests were performed to verify the suitability of the selected material for use in the specific conditions of the oral cavity. The performed tests showed that the proposed material is not only beneficial in relation to the existing commercial dental alloys but also meets the general criteria set for this type of elements.Conclusions
A more beneficial use of two–part ball latches (two key parts – patrix, matrix) was noticed in comparison to latches consisting of three parts (patrix, insert, matrix). On the basis of the obtained test results, it can be concluded that the proposed own design of a ball latch is a good alternative for traditional constructional and material solutions of commercial ball latches. 相似文献5.
目的归纳总结特色针法治疗脑卒中病的作用机制及临床应用情况。方法查阅了近10年关于特色针法治疗脑卒中的相关文献报道,并从理论基础、临床实践和机理研究三方面就项针、眼针、舌针等3种特色针法治疗脑卒中及其后遗症的研究总结。该法通过经络系统将项、眼及舌部与脏腑联系起来,针刺这些部位,既有"近治作用"以治咽喉、舌、眼的病症而治标,又有"远治作用"使五脏六腑之精气上荣于脑,以疏通脑部经络、行气活血而治本。结果特色针法治疗脑卒中的各项研究表明,通过选取项、眼及舌部穴位或功能区针刺,可增加患者脑血流量,减轻脑缺血再灌注损伤,达到脑保护作用,明显改善脑卒中后遗症。结论项针、眼针、舌针等3种特色针法可改善脑卒中患者脑部血液循环,促进血管的再生和神经功能的恢复,促进脑功能的恢复。 相似文献
