Recently a range of ocular manifestations such as retinal and lens amyloid-beta accumulation and retinal nerve fiber layer loss have been proposed as potential biomarkers in Alzheimer disease (AD). The TgCRND8 mouse model of AD exhibits age-dependent amyloid β (Aβ) oligomers accumulation and cognitive defects, amyloid plaques and hyperphosphorylated Tau deposition and inflammation. We proved the correlation between ocular pathologies and AD, observing increased levels of p-APP and p-Tau, accumulation of Aβ oligomers in the retina, eye, and optic nerve. The accumulation of amyloid markers was significantly stronger in the retinal ganglion cell (RGC) layer, suggesting that RGC might be more susceptible to degeneration. We detected a thinning of the RGC layer as well as RGC death in the retina of TgCRND8 mice, by using a combination of Optical Coherence Tomography (OCT), immunofluorescence, immunohistochemistry and Western blotting techniques. We proved for the first time the key role of C-Jun N-terminal Kinase (JNK) in the ocular degeneration. In support of this, the administration of the JNK inhibitor, D-JNKI1, was able to counteract the Aβ and p-Tau accumulation in the retina of TgCRND8 mice, and consequently reduce RGCs loss. These results confirm that degenerative changes in the retina/eye of AD mouse model mirrors the events observed in the brain parenchyma. Ocular changes can be detected by non-invasive imaging techniques, such as OCT, to study and test different therapeutic strategies against degenerative events associated to AD.
Aims
The aim was to explore nurses’ experiences of caring for and accompanying patients dying without the presence of family during the COVID‐19 pandemic.
Design
A qualitative descriptive design was used.
Methods
A purposive sample of registered nurses, caring for dying patients in Italian health‐care settings during the COVID‐19 pandemic, were selected. To capture a broad range of experiences, a maximum variety of participants about workplace, age, gender and work experience were included. A total of 31 nurses agreed to participate in the study; 28 participants were female; participants were aged 41 on average (range 25–63 years) and worked in hospitals and nursing homes in the Northern and Central Italian regions. Six focus groups were conducted from August to December 2020 through Microsoft Teams, reaching data saturation. The transcripts were analysed through inductive content analysis. The COREQ checklist was followed for study reporting.
Results
Four main categories emerged describing nurses’ experiences: hugely increased deaths in time of COVID‐19; ensuring physical, emotional, interpersonal and spiritual care for dying patients and supporting their families despite difficulties; ensuring care procedures of patients’ bodies after death and psychological consequences of caring for dying people during the pandemic.
Conclusion
Registered nurses provided physical, spiritual and emotional care to dying patients during the pandemic, despite limited resources and knowledge, standing in for relatives who were not allowed to visit them; the experiences of caring for dying patients in the absence of the family caused emotional distress in nurses.
Impact
Health‐care systems should develop guidelines aiming to meet the psychological needs of dying people in case of restrictions on patients’ family visits. Health‐care administrators should offer services to support the grieving process of relatives who cannot accompany dying patients and to reduce emotional distress in nurses caring for dying patients.
Background Health outcomes of older subjects with hip fracture (HF) may be negatively influenced by multiple comorbidities and frailty. An integrated multidisciplinary approach (i.e. the orthogeriatric model) is, therefore, highly recommended, but its implementation in clinical practice suffers from the lack of shared management protocols and poor awareness of the problem. The present consensus document has been implemented to address these issues. Aim To develop evidence-based recommendations for the orthogeriatric co-management of older subjects with HF. Methods A 20-member Expert Task Force of geriatricians, orthopaedics, anaesthesiologists, physiatrists, physiotherapists and general practitioners was established to develop evidence-based recommendations for the pre-, peri-, intra-and postoperative care of older in-patients (≥ 65 years) with HF. A modified Delphi approach was used to achieve consensus, and the U.S. Preventive Services Task Force system was used to rate the strength of recommendations and the quality of evidence. Results A total of 120 recommendations were proposed, covering 32 clinical topics and concerning preoperative evaluation (11 topics), perioperative (8 topics) and intraoperative (3 topics) management, and postoperative care (10 topics). Conclusion These recommendations should ease and promote the multidisciplinary management of older subjects with HF by integrating the expertise of different specialists. By providing a convenient list of topics of interest, they might assist in identifying unmet needs and research priorities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
