Functional somatic symptoms (FSS) is an umbrella term for symptoms inadequately explained by structural disease or damage. FSS show complex causality, and fall between the gaps in mainstream medical epistemology and/or mind-body dualism. Lack of explanations for FSS exacerbates uncertainty, anxiety and stigma for patients, and contributes to fragmented care and inappropriate management. We aimed to develop an open access health-educational resource that provides an acceptable, relevant, and usable explanatory model of FSS to internet users.

We carried out a participatory design study to develop the website bodysymptoms.org. Explanatory concepts were developed through iterative stages of dialogue between individuals with lived experience of multi-system FSS (n = 7), researchers, healthcare professionals and designers/developers. Initial explanatory components were collected from currently existing patient education about FSS, a review of the literature, and participants’ illness narratives. Principles were developed to filter, and organize these explanatory components into a coherent model. The model was translated into 5 European languages and through iterative rounds of feedback incorporated a diverse range of perspectives.

We describe the explanatory model that developed through the bodysymptoms project, and considerations that arose through the dialogic process. The model is based on the body as a complex adaptive system with causal interactions operating across bio-psycho-socio-ecological levels. Mechanistic processes that can maintain persistent symptoms were chosen as the main nodes (or topics) of the model, and minor topics were structured to demonstrate interactions between mechanisms. Considerations that arose during the process included coherence across philosophic, scientific and clinical levels of explanation; a therapeutic model of agency, within which explanations empowered without blame; the need to introduce notions of biological time, like body rhythms and body memory; and the role of multi-media, embodied metaphors and lived experience narratives in communication of the explanatory model. Personalisation of the model was achieved through embedding the structure of the model into the graphical and navigational structure of the website, which allows website visitors to explore the model in a non-linear manner, tailored by relevance, acceptability, and prefered level of information.

We present results from a research in action study to develop a novel resource for understanding functional somatic symptoms. bodysymptoms.org is based on the model of the body as a complex system that adapts in personal ways. To explain FSS there is a need for new ways to understand the body and how we become unwell. Bringing diverse perspectives into dialogue generated new forms of knowledge and allowed the power of scholarship to be harnessed for immediate shared value.

Shortages of personal protective equipment during the coronavirus disease 2019 (COVID-19) pandemic have led to the extended use or reuse of single-use respirators and surgical masks by frontline healthcare workers. The evidence base underpinning such practices warrants examination.

To synthesize current guidance and systematic review evidence on extended use, reuse, or reprocessing of single-use surgical masks or filtering face-piece respirators.

We used the World Health Organization, the European Centre for Disease Prevention and Control, the US Centers for Disease Control and Prevention, and Public Health England websites to identify guidance. We used Medline, PubMed, Epistemonikos, Cochrane Database, and preprint servers for systematic reviews.

Two reviewers conducted screening and data extraction. The quality of included systematic reviews was appraised using AMSTAR-2. Findings were narratively synthesized.

In total, 6 guidance documents were identified. Levels of detail and consistency across documents varied. They included 4 high-quality systematic reviews: 3 focused on reprocessing (decontamination) of N95 respirators and 1 focused on reprocessing of surgical masks. Vaporized hydrogen peroxide and ultraviolet germicidal irradiation were highlighted as the most promising reprocessing methods, but evidence on the relative efficacy and safety of different methods was limited. We found no well-established methods for reprocessing respirators at scale.

Evidence on the impact of extended use and reuse of surgical masks and respirators is limited, and gaps and inconsistencies exist in current guidance. Where extended use or reuse is being practiced, healthcare organizations should ensure that policies and systems are in place to ensure these practices are carried out safely and in line with available guidance.

The “chronic cerebrospinal venous insufficiency” or “CCSVI” hypothesis, namely that multiple sclerosis (MS) is caused by abnormalities in the azygous and internal jugular veins with subsequent alterations in venous hemodynamics in the central nervous system, has been a dominant topic in MS care in Canada over the past year. Although there is no methodologically rigorous evidence to support this hypothesis presently, a considerable number of MS patients have undergone endovascular CCSVI procedures. Such procedures include angioplasty or stent placement in jugular and azygous veins. The safety and efficacy of these procedures is unknown, but not without risk.

Chart and patient review of five patients with confirmed MS followed in Calgary were undertaken after patients came to medical attention by referral or admission secondary to complications believed to be associated with CCSVI procedures.

Complications upon investigation and review included internal jugular vein stent thrombosis, cerebral sinovenous thrombosis, stent migration, cranial nerve injury and injury associated with venous catheterization.

As the debate about CCSVI and its relationship to MS continues, the complications and risks associated with venous stenting and angioplasty in jugular and azygous veins are becoming clearer. As increasing numbers of MS patients are seeking such procedures, these five cases represent the beginning of a wave of complications for which standardized care guidelines do not exist. Our experience and that of our colleagues will be used to develop guidelines and strategies to monitor and manage these patients as their numbers increase.
