Astaxanthin-loaded brain-permeable liposomes for Parkinson's disease treatment via antioxidant and anti-inflammatory responses

Parkinson's disease is a neurodegenerative disorder characterized by cardinal motor symptoms resulting from the loss of dopaminergic neurons in the substantia nigra pars compacta. Although current medications may alleviate its symptoms, Parkinson's disease remains incurable. Astaxanthin is an antioxidant and anti-inflammatory agent; however, its high susceptibility to oxidative degradation and low aqueous solubility limit its therapeutic efficacy. This study aimed to improve the pharmaceutical properties and neuroprotective effects of astaxanthin for Parkinson's disease treatment by using lactoferrin-conjugated astaxanthin-loaded liposomes (Lf-ASX-LPs). We successfully formulated Lf-ASX-LPs with high encapsulation efficiency (97.6%) and favorable physical characteristics (diameter: 109.8 ± 1.1 nm; polydispersity index: 0.18 ± 0.01; zeta potential: - 9.5 ± 1.1 mV). Lf-functionalized liposomes demonstrated enhanced cellular uptake and permeation in a Transwell® study, showing a 16.7-fold higher internalization in SH-SY5Y cells over 24 h than those without Lf conjugation. Additionally, Lf functionalization enhanced brain penetration ability, as demonstrated by a biodistribution study using nude mice, compared to LPs without Lf conjugation. In vitro, Lf-ASX-LPs reduced cell loss by 20.1% and oxygen species by 30.0%, ameliorated the reduction in mitochondrial membrane potential under 1-methyl-4-phenylpyridinium-induced toxicity by 40.1%, and reduced extracellular nitric oxide levels under lipopolysaccharide-induced toxicity by 32.0%, indicating cytoprotective and antioxidant effects. In a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson's disease mouse model, treatment with Lf-ASX-LPs resulted in 5.0-, 3.1-, and 5.6-fold increases in dopamine levels, TH+ fiber density, and TH+ neurons, respectively, restoring dopaminergic neuron damage. The developed formulation also alleviated behavioral impairment and neuroinflammation, reducing astrocyte and microglial activation in the striatum and substantia nigra of the MPTP-treated animals. Thus, our formulation of Lf-ASX-LPs represents a promising strategy for providing neuroprotection and retarding Parkinson's disease progression.

Netnography: A novel methodology for nursing research

AIM

The aim of this paper is to critically reflect on our team's experience of using netnography to explore vaccine-hesitant parents and pregnant women, a group who have traditionally been difficult to recruit to research studies and a methodology that is underutilized in nursing research.

DESIGN

This paper takes the form of a discussion paper that will utilize data obtained from a qualitative netnographic study. Relevant literature was searched including 2015-2023.

METHOD

This paper utilized data obtained from a qualitative study that used netnography as methodology and an online minable data source. Netnography is a relatively new methodology that uses the online environment to explore digital cultures and study networked society. It pays particular attention to cultural insights and conditions that impact the human experience. This methodology is particularly relevant to nursing research which is often humanistic and always conducted to ensure optimal patient outcomes.

RESULTS

Using netnography for the first time has resulted in four main insights. These include the adaptability of the process; the creativity involved in designing the site; the ready acceptance of the site by participants and the co-creation knowledge that resulted.

CONCLUSIONS

Netnography is a creative methodology that was successful in accessing and engaging the vaccine-hesitant community, a group who are often marginalized. Netnography has the advantage of using a platform that is familiar and safe for many people and provides access to an extensive minable data source.

A Mapping Review of Netnography in Nursing

People use the Web to seek health-related information and to discuss health issues with peers. Netnography, a qualitative research methodology, has gained the attention of researchers interested in people's health and health issues. However, no previous reviews have accounted for how netnography is used in nursing research. The purpose of this mapping review was to generate a map of netnographic research in nursing. The search was conducted in PubMed, Academic Search Elite, the Cumulative Index to Nursing and Allied Health Literature, Medline, PsycINFO, Scopus, and Web of Science. Data were extracted from 53 original articles. The results show an increasing trend in published netnographies over time; 34% of the total sample was published in 2021. Of the total, 28% originated from Sweden, and 81% had used a covert approach. In studies in which the researchers used more participatory designs, the time spent on online forums ranged between 4 weeks and 20 months. Informed consent is found to be an issue in netnographic studies. We discuss the fact that nursing researchers have used netnography to address a wide range of research topics of concern and interest, from self-care support in an online forum for older adults to nursing students' perspectives on effective pedagogy. In line with the digital transformation in society in general, we discuss the fact that netnography as a research methodology offers great opportunities for nurse researchers to monitor new spaces and places that presuppose online methodological knowledge.

The central role of peers facilitators in the empowerment of breast cancer patients: a qualitative study

BACKGROUND

In 2020, the number of new cancer cases was estimated at 20 490 862 worldwide up from 18.1 million in 2018 and 14.1 million in 2012. Since the 2000s, cancer treatments have significantly improved, allowing either a cure or control of the disease. Patients share their experience of the disease and use supportive care solutions through involvement in patient associations and online forums. All the associations were built on the principle of "peer support," which is based on mutual aid between people who suffer or have suffered from the same somatic or psychological illness or had the same life experience. This experiential knowledge can be explored to understand the role of peers and associations in the appropriation of their cancer.

METHODS

A qualitative phenomenological study was undertaken through semi-structured interviews with 12 participants. Interviews were audio-recorded, transcribed verbatim, then analyzed by means of triangulation up to the point of theoretical saturation by a semio-pragmatic method.

RESULTS

Four categories emerged: (1) "Transforms a painful experience into a positive one. It mobilizes the human values of sharing, love, and humility, which facilitates resilience"; (2) "The characteristics of the association, a non-medical place between people sharing a common destiny, resonates with patients' needs and improves their well-being"; (3) "The association transforms the patients' experiences by facilitating engagement that leads to a patient-expert (empowerment)"; and (4) "Understanding what is happening to them is soothing, reassuring, because patients' concerns need to be heard and their care understood".

CONCLUSIONS

This study highlights patient associations can serve as the mediator of NPI and facilate the empowerment of breast cancer patients.

PRACTICE IMPLICATIONS

Educating health professionals in initial and continuing education about non-pharmacological interventions will be a major issue. Teaching the patient-centred approach to health professionals is one of the priorities in initial and continuing medical education.
