Practice developments supporting change implementation in Wellington,New Zealand (NZ) for ‘continuity of care when transitioning complex preterm infants from NICU to home’

The discussion paper will focus on continuity of care relating to previous NZ research, specifically to transitioning complex preterm infants from NICU to home based on parent experiences, and on the practice developments that have occurred, to ensure optimal health outcomes. Previous NZ research discovered parent desire a consistent service delivery for the entire transition journey from NICU and at home.An informative and comprehensive opportunity has occurred for reflective professional practice, evaluation, development and implementation which have transpired in positive change through innovative practice developments and support change implementation in Wellington, NZ. This has resulted in the articulation of a model of care that has both embraced and integrated parental desires for a continuity of care process for complex preterm infants. This has been achieved by having the same Discharge Facilitator/Key Case Manager present within the NICU and external to the NICU for Home-based infants for the entire transition journey.The paper will focus and emphasis additional practice development changes and furthermore, will present a real purpose, for other countries to learn of such practice developments that have exemplified a celebratory success for families of Wellington, NZ.     

How can hospitals change practice to better implement smoking cessation interventions? A systematic review

Smoking cessation reduces the risk of death, improves recovery, and reduces the risk of hospital readmission. Evidence and policy support hospital admission as an ideal time to deliver smoking-cessation interventions. However, this is not well implemented in practice. In this systematic review, the authors summarize the literature on smoking-cessation implementation strategies and evaluate their success to guide the implementation of best-practice smoking interventions into hospital settings. The CINAHL Complete, Embase, MEDLINE Complete, and PsycInfo databases were searched using terms associated with the following topics: smoking cessation, hospitals, and implementation. In total, 14,287 original records were identified and screened, resulting in 63 eligible articles from 56 studies. Data were extracted on the study characteristics, implementation strategies, and implementation outcomes. Implementation outcomes were guided by Proctor and colleagues' framework and included acceptability, adoption, appropriateness, cost, feasibility, fidelity, penetration, and sustainability. The findings demonstrate that studies predominantly focused on the training of staff to achieve implementation. Brief implementation approaches using a small number of implementation strategies were less successful and poorly sustained compared with well resourced and multicomponent approaches. Although brief implementation approaches may be viewed as advantageous because they are less resource-intensive, their capacity to change practice in a sustained way lacks evidence. Attempts to change clinician behavior or introduce new models of care are challenging in a short time frame, and implementation efforts should be designed for long-term success. There is a need to embrace strategic, well planned implementation approaches to embed smoking-cessation interventions into hospitals and to reap and sustain the benefits for people who smoke.     

前瞻性护理干预在急性心力衰竭患者中的应用

目的探讨前瞻性护理干预在急性心力衰竭患者中的应用效果。方法选取2018年4月—2020年5月河南省某医院收治的122例急性心力衰竭患者为研究对象,采用随机数字表法分为观察组与对照组,每组61例。对照组患者采用常规护理,观察组患者采用前瞻性护理,比较2组患者的干预效果、并发症发生情况,干预前后焦虑自评量表(SAS)、抑郁自评量表(SDS)评分及护理满意度。结果观察组患者干预总有效率为95.08%,高于对照组的75.41%,差异有统计学意义(χ²=9.385,P=0.002)。观察组患者并发症发生率为3.28%,低于对照组的18.03%,差异有统计学意义(χ²=6.974,P=0.008)。2组患者干预后SAS及SDS评分均低于干预前,且观察组低于对照组,差异均有统计学意义(P<0.05)。观察组患者护理满意度为98.36%,高于对照组的86.89%,差异有统计学意义(χ²=4.319,P=0.038)。结论前瞻性护理干预用于急性心力衰竭患者,有助于改善患者负性情绪及减少并发症的发生。     

School physical activity policies and associations with physical activity practices and behaviours: A systematic review of the literature

The development and implementation of school policies is considered a key strategy for the promotion of physical activity (PA) in children and adolescents. This study aimed to systematically review and synthesise existing literature focusing on the associations between formal written school-based PA policies and (a) school PA practices and (b) PA behaviours of school-aged children and adolescents. Fifty-one papers reporting on 52 studies met the eligibility criteria. All but two studies were from high income countries, most used cross-sectional designs and demonstrated fair methodological quality, and just over a third examined language aspects of policies. Findings predominantly indicated a lack of or inconclusive associations between the various characteristics examined and PA outcomes. Inconclusive associations were identified between both PA practice and behaviour outcomes and state level policies, policies focusing on PE and school-day PA, and in studies examining language aspects of policies. Inconclusive associations with both types of outcomes were more likely to be identified compared to a lack of associations in studies using self-report measures and in studies not providing information about the quality of exposure and outcome measures used. Overall, findings highlight the need for further research that acknowledges the complex relationship between school policies and PA outcomes and employs robust methodological approaches to enhance our understanding of this area.     

不同手术方法治疗儿童基本型外斜视对术后侧转非共同性的影响

目的：研究不同手术方法治疗儿童基本型外斜视与术后侧转非共同性发生及矫正效果相关性。

方法：回顾性研究。选取2018-06/2020-12于我院眼科接受治疗的180例基本型外斜视患儿临床资料。根据手术方式分为单眼一退一截术组(R&R组)104例和双眼外直肌后徙术组(BLR-rec组)76例。比较两组患者一般资料、手术矫正效果，以及随访期间手术斜视度数、侧转非共同性发生情况。

结果：两组患者术后3d，1、6mo视近、视远斜视度比较均无差异(均P>0.05)。R&R组术后不同时间点正位率高于BLR-rec组(P<0.05)。R&R组较BLR-rec组发生侧转非共同性的风险更低(OR=0.524， Wald χ²=4.260， P=0.039)。两组患者术后6mo主要表现在水平直肌手术眼外展方向注视，但两组患儿视远和视近侧转非共同性发生率均无差异(均P>0.05)。

结论：R&R对于儿童基本型外斜视的矫正效果优于BLR-rec术式，可降低侧转非共同性发生情况。

Practical approaches to labelling terminal alkynes with deuterium

Base catalysed exchange with sodium hydroxide, calcium oxide or N,N,N,N-tetramethylguanidine in deuterium oxide is a viable procedure for the preparation of terminally deuterated alkynes for those alkynes stable to strong base. The use of silver perchlorate as a catalyst is an alternative practical option when labelling alkynes which are sensitive to base or contain functionalities which would lead to labelling elsewhere in the molecule. Labelling with this catalyst takes place smoothly at ambient temperature in a mixture of N,N-dimethylformamide and deuterium oxide.     

Preliminary study on blood coagulation and hemostatic effect and acute toxicity of Oxalis corniculata L. ethanol extract

In the present study, we aimed to observe the effects of ethanol extract of Oxalis corniculata L. on bleeding time (BT) and coagulation time (CT) and determine its acute toxicity in mice. Firstly, the ethanol extract of O. corniculata was administered to 40 mice, which were randomly divided into the normal control group, Yunnan Baiyao control group, low-dose group, and high-dose group. The low-dose (0.6 g/kg) and high-dose (1.2 g/kg) groups received ethanol extract of O. corniculata by gavage, and the BT and CT of the mice were measured by the slide method and tail clipping method, respectively. Secondly, the median lethal dose method was used with 50 mice to observe the physiological state, poisoning reaction, and death of the mice after intragastric administration. Finally, on the 14th day of the experiment, a necropsy was performed to observe any abnormality of the organs. In conclusion, in the coagulation and hemostasis tests, there were no statistical differences between the groups (P > 0.05), while there was a significant dose-response relationship, and the BT and CT were significantly shorter than those of the negative control group, which were comparable to the Yunnan Baiyao control group. Moreover, in the acute toxicity test, the median lethal dose of ethanol extract of O. corniculata was 6.0291 g/kg, with a 95% confidence interval of 5.3065–6.7829 mg/kg.
