This study aimed to systematically review Clinical Practice Guidelines (CPGs) for nutritional management of dementia and use evidence mapping to highlight research trends and identify gaps to inform future research.
A systematic review of guidelines using the PRISMA statement.
Systematically collect literature on dementia management CPGs from PubMed, Embase, Web of Science and guideline databases. Extract basic information, recommendations, methodological quality and reporting quality of the CPGs. Four researchers independently evaluated eligible CPGs using the AGREE II instrument and the RIGHT checklist. All recommendations from the CPGs were summarised and analysed, and evidence mapping bubble charts were created in Excel.
After excluding 5541 records, 10 CPGs were eventually proved eligible, 5 of which were of high quality and 5 of high quality. With 10 CPGs that combined 18 recommendations. The nutrition screening and assessment were summarised on the basis of the dementia recommendations for 4 major items, 7 items on nutritional interventions, 5 items on caring and 2 on education.
This review provides an evidence map and offers new perspectives on CPGs for nutritional management in dementia. However, there are improvements to the included CPGs, but most CPGs have a number of key recommendations that can help guide clinical practice.
The currently available guidelines on dementia nutritional management have room for methodological improvement.
The present study aimed to investigate the effect of local oxygen therapy combined with vacuum sealing drainage (VSD) on the healing of stage IV pressure ulcers sacrococcygeal. In this prospective study, we included a total of 98 patients with stage IV sacrococcygeal pressure ulcers in our hospital between February 2021 and June 2022. The patients enrolled were randomly and equally divided into two groups: the study group (undergoing local oxygen therapy combined with VSD treatment) and the control group (receiving conventional treatment). The wound healing time and hospital stay were compared between the two groups. Additionally, the wound area, tissue type, wound exudation and pain intensity were assessed before treatment, 10, 20, 30 and 40 days after treatment. The incidence of complications was also calculated. The study group demonstrated significantly shorter wound healing time and hospital stays compared to the control group (p < 0.05). Before treatment, there were no significant differences in terms of wound area, tissue type and wound exudation between the two groups (p > 0.05); after 10, 20, 30 and 40 days of treatment, however, evidently smaller wound areas, improved tissue types and reduced wound exudation were observed in the study group compared to the control group (p < 0.05). Furthermore, the study group exhibited increased microvascular count compared to the control group (p < 0.05). Before treatment, there was no significant difference in pain intensity between the two groups (p > 0.05), whereas markedly lower pain intensity was seen in the study group than in the control group after 10, 20, 30 and 40 days of treatment (p < 0.05). The incidence of complications did not significantly differ between the two groups after 40 days of treatment (p > 0.05). Local oxygen therapy combined with VSD was found to effectively accelerate the healing process of stage IV sacrococcygeal pressure ulcers, leading to shorter hospital stays and improved patient prognosis. This combined therapy shows promise for widespread application in clinical practice.
