Use of artificial intelligence and machine learning for the management of fibromyalgia: a scoping review

Abstract:

Background: Fibromyalgia (FM) is a complex and multifactorial syndrome characterized by widespread pain, fatigue, cognitive impairment, and other systemic symptoms. The absence of specific biomarkers and the heterogeneous clinical presentation pose significant diagnostic challenges.

Objective: This scoping review aims to explore the current applications of artificial intelligence (AI) and machine learning (ML) in the diagnosis and clinical management of FM.

Methods: A systematic search was conducted in PubMed, EMBASE, and the Cochrane Library using defined keywords related to FM and AI/ML. Studies were included if they addressed ML applications in FM patients. Following PRISMA-ScR guidelines, 43 studies published between 2011 and 2024 were included and analyzed for ML techniques used, diagnostic targets, data types, and clinical relevance.

Results: As expected, the majority of studies done so far focused on improving diagnostic accuracy through supervised algorithms such as support vector machines, neural networks, and ensemble models, as well as unsupervised clustering and dimensionality reduction techniques. Notable findings include the identification of neurophysiological signatures via fMRI, gene expression patterns, retinal imaging changes, and metabolomic biomarkers that distinguish FM patients from controls. For instance, one study investigating circulating microRNAs used a Random Forest model to identify 11 microRNAs (e.g. hsa-miR-28-5p, hsa-miR-29a-3p, hsa-miR-150-5p) capable of differentiating patients with FM, ME/CFS, and healthy controls, suggesting their potential as biomarkers for more accurate diagnoses. Reported model accuracies ranged from 82% to 100%, although most studies were pilot-based with small and imbalanced samples, limiting generalizability.

Conclusion: AI and ML offer promising tools to overcome longstanding limitations in FM diagnosis and treatment. While current findings demonstrate significant potential, larger, multicenter studies with rigorous validation protocols are essential to finally establish these approaches as clinically reliable solutions.

Burden of Disease in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS): A Scoping Review

Abstract:

Objective: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a serious chronic and complex multi-system disease characterised by symptoms such as post-exertional malaise, fatigue, cognitive impairment and pain. Diagnosis is based on international consensus criteria, and no curative treatment is available. In the USA, its prevalence is estimated at 0.42% among adults, with women affected three times as often as men. Prevalence is expected to increase due to the COVID-19 pandemic. In addition to its severe symptoms, ME/CFS has a substantial economic impact. This scoping review aimed to systematically examine the global health, social and economic burden of ME/CFS.

Methods: We conducted a systematic literature search following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) guidelines in six databases and supplemented it with a citation search. We assessed study quality using a modified version of the Mixed Methods Appraisal Tool.

Results: We included 20 studies that assessed costs (n = 16), disability-adjusted life years (DALYs) (n = 3), employment rates (n = 1), and school attendance (n = 1) as indicators of disease burden. Reported costs per patient ranged from USD 2,916 to USD 119,611, with indirect costs accounting for the largest proportion. DALYs reported for the USA ranged from 0.714 million in 2016 to 5.77 million in 2022.

Conclusion: ME/CFS imposes a substantial health, social and economic burden of disease. Discrepancies in estimates are probably due to differences in study samples, methodologies, cost components, and healthcare systems. Because ME/CFS is assumed to be underdiagnosed, its true burden may be even higher.

Multimodal treatment strategies for homebound people with severe ME/CFS: a scoping review

Abstract:

Purpose: This scoping review aims to provide an overview of previously published treatment strategies that are multimodal, rather than purely drug-based and may be considered for home- or bedbound ME/CFS patients. Thus, the focus lies upon the analyses of telemedicine as well as home treatment elements. In addition, the evaluation and assessment methods used in these studies will be further discussed.

Methods: Using the scoping review method, a literature analysis was conducted resulting in a total of 14 publications which met the predefined criteria. Inclusion was based on models applicable to housebound individuals with ME/CFS, focusing on social medicine and psychological support services rather than individual drug strategies.

Results: The analysis demonstrated that the appropriate treatment methods were predominantly home visits (n=5) or a telemedicine format (n=7). Studies which used alternative settings were included if conversion to a telemedicine format was viable. The important factors highlighted in several studies (n=8), when considering this patient group, were individualisation and flexibility of the treatment methods – and thus the ability to address the day-to-day levels of impairment. The explicit involvement of families in the treatment plan were described in a total of six studies. In ten articles, the treatment concept was additionally evaluated, predominantly using questionnaires (n=7), whilst the questionnaires used were not consistent. Qualitative evaluations were invariably conducted using Brown and Clarke‘s thematic analysis (n=3).

Conclusion: Publications on multimodal treatment strategies for homebound ME/CFS patients are rare. However approaches using home visits or telemedicine are described. The majority of identified publications addressed the need for individualised as well as flexible patient care, whilst some were dedicated to the added value of involving the patients’ family. The data outline the specific challenges associated with the care of severely affected ME/CFS patients that should also be considered in the context of research.

A systematic scoping review of how people with ME/CFS use the internet

Abstract:

Purpose: Myalgic Encephalomyelitis (ME) is a chronic neurological illness also known as Chronic Fatigue Syndrome (CFS). Key symptoms are extreme fatigue, post-exertional malaise, cognitive problems and sleep disturbance. With reported higher levels of online activity for people with ME/CFS than other conditions, more knowledge of characteristics and experience of online use in everyday life is needed. This scoping review systematically identified, appraised and synthesised what is known on how people with ME/CFS use the internet.

Method: The following bibliographic databases were searched: Embase, Medline, PsychINFO, Cinahl, AMED, and ASSIA, plus Web of Science, ProQuest Dissertations & Theses Global, Scopus, and Google Scholar for grey literature. Two reviewers independently screened title-abstracts, and full text of studies against inclusion criteria. Remaining studies were quality-assessed using appropriate critical appraisal tools.

Results: Many people with ME/CFS go online daily to gain information and share experiences of their illness including difficulties with family, friends and doctors. Reciprocity of emotional and social support was found with a sense of in-group belonging and empowerment. Validation was sought online, and identity renegotiation took place. Some replacement of offline social support for online engagement was reported. Online lay expertise was seen to improve offline health professional relations but not replace them.

Conclusions: The internet is a valued source of support for people with ME/CFS in terms of sharing of experiences, legitimacy, empowerment, and integration into people’s everyday lives. The extent of interrelating of online and offline lives is not clear however and needs further investigation.

Cannabinoids and the Endocannabinoid System in Early SARS-CoV-2 Infection and Long COVID-19—A Scoping Review

Abstract:

Coronavirus disease-19 (COVID-19) is a highly contagious illness caused by the SARS-CoV-2 virus. The clinical presentation of COVID-19 is variable, often including symptoms such as fever, cough, headache, fatigue, and an altered sense of smell and taste. Recently, post-acute “long” COVID-19 has emerged as a concern, with symptoms persisting beyond the acute infection. Vaccinations remain one of the most effective preventative methods against severe COVID-19 outcomes and the development of long-term COVID-19. However, individuals with underlying health conditions may not mount an adequate protective response to COVID-19 vaccines, increasing the likelihood of severe symptoms, hospitalization, and the development of long-term COVID-19 in high-risk populations.
This review explores the potential therapeutic role of cannabinoids in limiting the susceptibility and severity of infection, both pre- and post-SARS-CoV-19 infection. Early in the SARS-CoV-19 infection, cannabinoids have been shown to prevent viral entry, mitigate oxidative stress, and alleviate the associated cytokine storm. Post-SARS-CoV-2 infection, cannabinoids have shown promise in treating symptoms associated with post-acute long COVID-19, including depression, anxiety, post-traumatic stress injury, insomnia, pain, and decreased appetite. While current research primarily focuses on potential treatments for the acute phase of COVID-19, there is a gap in research addressing therapeutics for the early and post-infectious phases. This review highlights the potential for future research to bridge this gap by investigating cannabinoids and the endocannabinoid system as a potential treatment strategy for both early and post-SARS-CoV-19 infection.

Functional neurological disorder and functional somatic syndromes among sexual and gender minority people: A scoping review

Abstract

Objective: To describe the current literature on functional neurological disorder and functional somatic syndromes among sexual and gender minority people (SGM).

Methods: A search string with descriptors of SGM identity and functional disorders was entered into PubMed, Embase, Web of Science, PsycInfo, and CINAHL for articles published before May 24, 2022, yielding 3121 items entered into Covidence, where 835 duplicates were removed.

A neurologist and neuropsychiatrist screened titles and abstracts based on predefined criteria, followed by full-text review. A third neurologist adjudicated discrepancies. Eligible publications underwent systematic data extraction and statistical description.

Results: Our search identified 26 articles on functional disorders among SGM people. Most articles were case (13/26, 46%) or cross-sectional (4/26, 15%) studies. Gender minority people were represented in 50% of studies. Reported diagnoses included fibromyalgia (n = 8), functional neurological disorder (n = 8), somatic symptom disorder (n = 5), chronic fatigue syndrome (n = 3), irritable bowel syndrome (n = 2), and other functional conditions (n = 3).

Three cohort studies of fibromyalgia or somatic symptom disorder reported an overrepresentation of gender minority people compared to cisgender cohorts or general population measures.

Approximately half of case studies reported pediatric or adolescent onset (7/13, 54%), functional neurological disorder diagnosis (7/13, 54%), and symptom improvement coinciding with identity-affirming therapeutic interventions (7/13, 58%).

Conclusion: Despite a methodologically rigorous literature search, there are limited data on functional neurological disorder and functional somatic syndromes among SGM people. Several studies reported increased prevalence of select conditions among transgender people. More observational studies are needed regarding the epidemiology and clinical course of functional disorders among SGM people.

Healthcare system barriers impacting the care of Canadians with myalgic encephalomyelitis: a scoping review

Abstract:

Background: Myalgic encephalomyelitis (ME, also known as chronic fatigue syndrome or ME/CFS) is a debilitating, complex, multi-system illness. Developing a comprehensive understanding of the multiple and interconnected barriers to optimal care will help advance strategies and care models to improve quality of life for people living with ME in Canada.

Objectives: To: (1) identify and systematically map the available evidence; (2) investigate the design and conduct of research; (3) identify and categorize key characteristics; and (4) identify and analyze knowledge gaps related to healthcare system barriers for people living with ME in Canada.

Methods: The protocol was preregistered in July 2022. Peer-reviewed and grey literature was searched, and patient partners retrieved additional records. Eligible records were Canadian, included people with ME/CFS and included data or synthesis relevant to healthcare system barriers.

Results: In total, 1821 records were identified, 406 were reviewed in full, and 21 were included. Healthcare system barriers arose from an underlying lack of consensus and research on ME and ME care; the impact of long-standing stigma, disbelief, and sexism; inadequate or inconsistent healthcare provider education and training on ME; and the heterogeneity of care coordinated by family physicians.

Conclusions: People living with ME in Canada face significant barriers to care, though this has received relatively limited attention. This synthesis, which points to several areas for future research, can be used as a starting point for researchers, healthcare providers and decision-makers who are new to the area or encountering ME more frequently due to the COVID-19 pandemic.

A Scoping Review of ‘Pacing’ for Management of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS): Lessons Learned for the Long COVID Pandemic

Abstract:

Background Controversy over treatment for people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a barrier to appropriate treatment. Energy management or pacing is a prominent coping strategy for people with ME/CFS that involves regulating activity to avoid post exertional malaise (PEM), the worsening of symptoms after an activity. Until now, characteristics of pacing, and the effects on patients’ symptoms had not been systematically reviewed. This is problematic as the most common approach to pacing, pacing prescription, and the pooled efficacy of pacing was unknown. Collating evidence may help advise those suffering with similar symptoms, including long COVID, as practitioners would be better informed on methodological approaches to adopt, pacing implementation, and expected outcomes.

Objectives In this scoping review of the literature, we aggregated type of, and outcomes of, pacing in people with ME/CFS.

Eligibility criteria Original investigations concerning pacing were considered in participants with ME/CFS.

Sources of evidence Six electronic databases (PubMed, Scholar, ScienceDirect, Scopus, Web of Science and the Cochrane Central Register of Controlled Trials [CENTRAL]) were searched; and websites MEPedia, Action for ME, and ME Action were also searched for grey literature.

Methods A scoping review was conducted. Review selection and characterisation was performed by two independent reviewers using pretested forms.

Results Authors reviewed 177 titles and abstracts, resulting in included 17 studies: three randomised control trials (RCTs); one uncontrolled trial; one interventional case series; one retrospective observational study; two prospective observational studies; four cross-sectional observational studies; and five cross-sectional analytical studies. Studies included variable designs, durations, and outcome measures. In terms of pacing administration, studies used educational sessions and diaries for activity monitoring. Eleven studies reported benefits of pacing, four studies reported no effect, and two studies reported a detrimental effect in comparison to the control group.

Conclusions Highly variable study designs and outcome measures, allied to poor to fair methodological quality resulted in heterogenous findings and highlights the requirement for more research examining pacing. Looking to the long COVID pandemic, future studies should be RCTs utilising objectively quantified digitised pacing, over a longer duration of examination, using the core outcome set for patient reported outcome measures.

Interventions to support mental health in people with long COVID: a scoping review

Abstract:

Introduction: Long COVID (LC) is a multisystem disease with symptoms lasting weeks or months beyond the acute COVID-19 infection. Several manifestations are reported by people with LC, including effects on mental health, with varying degrees of psychological distress and disturbances to daily activities. Research conducted to identify effective interventions to support mental health among people with LC has been limited by the breadth and scope of studies.

Aim: This review aims to identify interventions being tested to support mental health of people with LC.

Methods: A scoping review was conducted by searching five databases for articles published between January 2020 and early October 2022 to identify research evaluating interventions focused on improving mental health symptoms associated with LC. Results from all sources were checked for eligibility by two reviewers, and agreements were resolved by discussion. Gray literature and reference list of included studies and relevant reviews were scrutinised to identify any additional studies. Data extraction was conducted by one reviewer and checked by another reviewer for accuracy.

Results: Of the 940 studies identified, 17 were included, the design of which varied but included mainly case studies (n = 6) and clinical trials (n = 5). Several interventions were described, ranging from single interventions (e.g., pharmacologic) to more holistic, comprehensive suites of services (pharmacologic and non-pharmacologic). Several mental health outcomes were measured, mostly anxiety and depression. All included studies were reported to be associated with improvements in participants’ mental health outcomes.

Conclusion: This scoping review identified studies reporting on a variety of interventions to support mental health among people with LC. Although positive changes were reported by all studies, some were case studies and thus their findings must be interpreted with caution. There is a need for more research to be conducted to identify the impact of interventions on mental health of people with LC.
