Brief mindfulness-based intervention of 'STOP (Stop, Take a Breath, Observe, Proceed) touching your face': a study protocol of a randomised controlled trial.

ABSTRACT: Introduction: Face-touching behaviour often happens frequently and automatically, and poses potential risk for spreading infectious disease. Mindfulness-based interventions (MBIs) have shown its efficacy in the treatment of behaviour disorders. This study aims to evaluate an online mindfulness-based brief intervention skill named 'STOP (Stop, Take a Breath, Observe, Proceed) touching your face' in reducing face-touching behaviour.

Methods and analysis: This will be an online-based, randomised, controlled, trial. We will recruit 1000 participants, and will randomise and allocate participants 1:1 to the 'STOP touching your face' (both 750-word text and 5 min audio description by online) intervention group (n=500) and the wait-list control group (n=500). All participants will be asked to monitor and record their face-touching behaviour during a 60 min period before and after the intervention. Primary outcome will be the efficacy of short-term mindfulness-based 'STOP touching your face' intervention for reducing the frequency of face-touching. The secondary outcomes will be percentage of participants touching their faces; the correlation between the psychological traits of mindfulness and face-touching behaviour; and the differences of face-touching behaviour between left-handers and right-handers. Analysis of covariance, regression analysis, ?² test, t-test, Pearson's correlations will be applied in data analysis. We will recruit 1000 participants from April to July 2020 or until the recruitment process is complete. The follow-up will be completed in July 2020. We expect all trial results to be available by the end of July 2020.

Ethics and dissemination: The study protocol has been approved by the Ethics Committee of Sir Run Run Shaw Hospital, an affiliate of Zhejiang University, Medical College (No. 20200401-32). Study results will be disseminated via social media and peer-reviewed publications.

Trial registration number: NCT04330352.

Project description:Approximately 20% of sleeping sickness patients exhibit respiratory complications which are commonly attributed to secondary bacterial infections, with an unknown role of the parasite. Using a Glossina morsitans tsetse fly initiated Trypansoma brucei infection in mice we found that parasites rapidly and permanently colonize the lungs, representing one of the major target organs next to the adipose tissue. Trypanosomes were found by immunofluorescence staining and scanning electron microscopy to occupy the extravascular spaces surrounding the blood vessels of the alveoli and bronchi. Parasites were even found in the lung cartilage. Trypanosomes were often observed as nests of multiplying parasites exhibiting close interactions with collagen and highly active secretion of extracellular vesicles that are engaged in intercellular communication. The local immune response was analysed by flow cytometry after 10 and 21 days of infection and was characterized by a substantial increase of CD11b+ Ly6C+ monocytes, CD11b+ Ly6C+ F4/80+ macrophages and CD11b+ CD11c+ dendritic cells. CD11b+ Ly6G+ neutrophils only accumulated prominently at the late infection time point. Interestingly, parasite presence resulted in a significant reduction of B220+ IgM+ B cells, CD11b+ CD11clo/- SiglecF+ eosinophils and TcR-β- NK1.1+ natural killer cells. Digital transcriptomics revealed infection-induced upregulation of Il-10, IFN-ɣ- and IFN-α-responses, IL-2-, IL-6- and TNF-signalling, a Th1 pro-inflammatory signature, negative immune checkpoint regulators and a predominant M1 macrophage polarization. Il12a and genes associated with complement and the B cell receptor were downregulated. No infection-associated pulmonary dysfunction could be detected by in vivo lung function measurements, mirroring the limited pulmonary complications during sleeping sickness. However, the substantial reduction of eosinophils, B cells and NK cells may render individuals more susceptible to opportunistic infections. Collectively, these observations provide essential insights in the peculiar parasite biology, immunological reactions and physiological function of a largely overlooked target organ which may trigger new diagnostic approaches for sleeping sickness.
