A qualitative study of the interaction experiences between family caregivers and community nurses for disabled elderly people at home.

BACKGROUND: Family members are currently the main caregivers of the disabled elderly people at home. With declining health and increasing frailty, caregiving of disabled elderly people becomes a task of family caregivers in conjunction with community nurses. Interaction between family caregivers and community nurses can effectively improve the quality of home care for the disabled elderly people. This study aimed to investigate the interaction experiences between family caregivers and community nurses for disabled elderly people at home. METHODS: This research was a study of qualitative descriptions based on semi-structured face-to-face interviews. This study was to purposefully select family caregivers of the disabled elderly and community nurses in Zhengzhou city, Henan Province and explore the interaction patterns between them. Directed content analysis method was used to generate qualitative codes and identify themes. RESULTS: A total of 12 interviews were completed, including 7 family caregivers and 5 community nurses. Four themes were identified: 1) Information interaction; 2) Emotional interaction; 3) Practical interaction; 4) Factors that promote and hinder the interaction. CONCLUSIONS: It was found that the interaction between family caregivers and community nurses was not optimistic. Lack of communication and collaboration between community nurses and caregivers. Providing a new perspective that we can develop and implement intervention to facilitate positive interactions, which will reduce the burden of family caregivers, bring the highest quality of care to older adults with disabilities and improve the quality of care for disabled elderly people.

Development of a family-community interaction programme in the treatment of women with postpartum depression: protocol for a randomised controlled trial.

INTRODUCTION: Postpartum depression has great harm and becomes a serious public health problem. Most women stay at home after childbirth, so the support from community and family is particularly important in the treatment of postpartum depression. The cooperation between family and community can effectively improve treatment effect of patients with postpartum depression. It is imperative to conduct a study on the collaboration and interaction among patients, family and community in the treatment of postpartum depression. METHODS AND ANALYSIS: The aim of this study is to determine the experience and demands of patients with postpartum depression, family caregivers and community providers for the interaction, construct an interaction intervention programme bettween family and community and promote the rehabilitation of patients with postpartum depression. From September 2022 to October 2022, this study will select postpartum depression patient families from seven communities in Zhengzhou City, Henan Province in China. The researchers, after training, will conduct semi-structured interview to collect research data. According to the integration results of qualitative research and literature review, the interaction intervention programme will be constructed and revised using the Delphi expert consultation method. Then the participants will be selected to accept the intervention of the interaction programme and evaluated through questionnaires. ETHICS AND DISSEMINATION: The study is approved by the Ethics Review Committee of Zhengzhou University (ZZUIRB2021-21). The results of this study will contribute to clarify the responsibilities of family subjects and community subjects in the treatment of postpartum depression, more effectively promote the rehabilitation of patients with postpartum depression and reduce the burden of family and society. Moreover, this research will be a profitable exploration at home and abroad. And the findings will be disseminated through conference presentations and peer-reviewed publications.

Solvent-Type Passivation Strategy Controls Solid-State Self-Quenching-Resistant Behavior in Sulfur Dots.

Treatment of sulfur dots with polyethylene glycol (PEG) has been an efficient way to achieve a high luminescence quantum yield, and such a PEG-related quantum dot (QD)-synthesis strategy has been well documented. However, the polymeric insulating capping layer acting as the "thick shell" will significantly slow down the electron-transfer efficiency and severely hamper its practical application in an optoelectric field. Especially, the employment of synthetic polymers with long alkyl chains or large molecular weights may lead to structural complexity or even unexpected changes of physical characteristics for QDs. Therefore, in sulfur dot preparation, it is a breakthrough to use short-chain molecular species to replace PEG for better control and reproducibility. In this article, a solvent-type passivation (STP) strategy has been reported, and no PEG or any other capping agent is required. The main role of the solvent, ethanol, is to directly react with NaOH, and the generated sodium ethoxide passivates the surface defects. The afforded STP-enhanced emission sulfur dots (STPEE-SDs) possess not only the self-quenching-resistant feature in the solid state but also the extension of fluorescence band toward the wavelength as long as 645 nm. The realization of sulfur dot emission in the deep-red region with a decent yield (8.7%) has never been reported. Moreover, a super large Stokes shift (300 nm, λex = 345 nm, λem = 645 nm) and a much longer decay lifetime (109 µs) have been found, and such values can facilitate to suppress the negative influence from background signals. Density functional theory demonstrates that the surface passivation via sodium ethoxide is dynamically favorable, and the spectroscopic insights into emission behavior could be derived from the passivation effect of the sulfur vacancy as well as the charge-transfer process dominated by the highly electronegative ethoxide layer.

Exploration of Sulfur-Containing Nanoparticles: Synthesis, Microstructure Analysis, and Sensing Potential.

In this work, three different sulfur sources such as sulfur powder, sodium sulfide, and sodium thiosulfate are selected to prepare sulfur-derived quantum dots (S-QDs), Na2S-derived nanoparticles (NS-NPs), and Na2S2O3--derived QDs (NSO-QDs) in the presence of NaOH or assisted by hydrogen peroxide etching. The low sulfur percentage in the above three samples and the synthesis experiments in the presence of nitrogen/oxygen all support that poly(ethylene glycol) (PEG) plays an important role during the assembly process and the definition of sulfur dots is not accurate. For photophysical features, remarkable green quantum dots (S-QDs) possess an excitation-independent emission peak at 500 nm. But NS-NPs and NSO-QDs demonstrate observable shift tendency, and the evolution of emission profiles varies from 480 to 586 nm. NSO-QDs can be used as a fluorescent probe for highly selective and quantitative detection of Ni2+ in an aqueous solution in the presence of potential interfering ions with a low detection limit (0.18 µM) and a wide linear range (8-380 µM). Their reusability performance has also been demonstrated by employing dimethylglyoxime as the restoration reagent.

Determination of Hypochlorite via Fluorescence Change from Blue to Green Based on 4-(1 H-imidazo [4,5-f] [1,10]-phenanthrolin-2-yl) Benzaldehyde Oxime.

The new design strategy will provide the possibility for preparing a dynamic sensor by employing the inhibition of C = N isomerization. In this work, the functional probe 4-(1 H-imidazo [4,5-f] [1,10]-phenanthrolin-2-yl) benzaldehyde oxime (compound 4) has been synthesized and such molecule gives rise to blue emission. Due to the incorporation of hypochlorite, the oxime group can be oxidized to the structure of aldehyde. As a result, the molecular motif exhibits sharp emission change from blue to green due to the addition of hypochlorite with enough sensitivity and selectivity (detection limit = 53 nM, linear range 0.5-8.0 µM). It has also been used for monitoring ClO- by employing solution color change and the absorption signal difference could effectively rule out the effects of interference species. To our knowledge, it will be the first case of a highly selective hypochlorite sensor derived from oxime isomerization reaction based on phenanthroline backbone.
