Effectiveness of low-level laser therapy in reducing pain score and healing time of recurrent aphthous stomatitis: a systematic review and meta-analysis

BACKGROUND

Recurrent aphthous stomatitis (RAS) is a common chronic inflammatory oral disease that negatively impacts the quality of life. Current therapies aim to reduce pain and healing process yet challenges such as rapid loss due to salivary flushing in topical drugs and adverse effects due to prolonged use of systemic medications require further notice. Low-level laser therapy is reported with immediate pain relief and faster healing thus preserving the potential for optimal treatment modalities. This review critically analyses and summarizes the effectiveness of LLLT in reducing pain scores and healing time of RAS.

METHODS

A systematic search was conducted in ScienceDirect, PubMed, and Scopus using keywords of low-level laser therapy, photo-biomodulation therapy, and recurrent aphthous stomatitis. RCTs between 1967 to June 2022, presenting characteristics of the laser and reporting pain score and/or healing time of RAS after irradiation were included. Animal studies and recurrent aphthous ulcers with a history of systemic conditions were excluded. Studies were critically appraised using the RoB 2 tool. A meta-analysis was performed using inverse variance random effects.

RESULTS

Fourteen trials with a total of 664 patients were included. Reduced pain was reported in 13 studies, while shortened healing time was presented in 4. The pooling of two studies after CO2 irradiation demonstrated faster healing time compared to placebo (MD - 3.72; 95% CI - 4.18, - 3.25).

CONCLUSION

Pain score and healing time of RAS were reduced after irradiation with LLLT. RoB resulted in "some concerns" urging well-designed RCTs with larger samples to further assess each laser application for comparison.

Characterizing attributes of innovation of technologies for healthcare: a systematic review

OBJECTIVES

Characterizing and evaluating the holistic value of innovative healthcare technologies (e.g. treatments, services) constitutes a crucial goal to maximize limited resources. However, the characteristics of innovation have not been well identified. This review aims to describe the characteristics of healthcare innovation.

METHODS

We performed a comprehensive systematic search using PubMed, Embase, PsycINFO, and Econlit from inception to July 2022. Articles were included if they described innovation or the characteristics of innovation of the technologies in healthcare. Characteristics or definitions of innovation directly or indirectly described as innovation were extracted from the included articles. Two independent reviewers then conceptualized the identified characteristics of innovation to generate innovation attributes in healthcare.

RESULTS

In total, 103 articles were included in this review. Eight attributes describing innovation, i.e. novelty, step change, substantial benefits, an improvement over existing technologies, convenience and/or adherence, added value, acceptable cost, and uncounted benefits, were conceptualized. Most of the identified innovation attributes were based on the researchers' perspective.

CONCLUSIONS

This study conceptualized innovation attributes in healthcare based on the characteristics of healthcare innovation as defined in the literature. Further research is warranted to obtain a complete understanding of the perspectives of researchers and other stakeholders, including patients, healthcare providers, healthcare payers, and the pharmaceutical industry, on recognizing innovation in healthcare.KEY POINTSThis is the first systematic review to conceptualize attributes of healthcare innovation.We conceptualized eight attributes describing innovation, i.e. novelty, step change, substantial benefits, an improvement over existing technologies, convenience and/or adherence, added value, acceptable cost, and uncounted benefits based on the similar concept.In existing literature, patients' and caregivers' perspectives were less frequently found to describe the innovation attributes.Future research is needed to identify, measure, and value various stakeholders, including patients' and caregivers' perspectives on healthcare innovation.

[Innovation in mental health from the perspective of users: a community movement in the Northeast of Brazil]

This study, originating from a multidimensional analysis on the innovation category in a Community Mental Health Movement of Bom Jardim (Fortaleza, Brazil) that examines subjective and psychosocial dimensions, seeks to examine to what extent the work developed by this movement is effectively an innovative model in mental healthcare from the perspective of users of this service. The methodology adopted was a qualitative case study method based on a critical-interpretive approach employing techniques such as in-depth interviews associated with focus groups. The categorization of the discursive material was conducted using a model based on the four main dimensions of psychiatric reform, namely conceptual, technical, legal and socio-cultural aspects. The results reveal the following: an emphasis on the individual rather than focusing on the sickness; care as the basis for purposeful actions; the co-production of genuine dialogue with multiple stakeholders, and the construction of autonomy emphasizing individual potential. In conclusion, it can be said that healthcare practices developed by the Movement involve deconstructing the traditional model of mental healthcare, permitting new forms of citizenship, thereby contributing to deinstitutionalization.
