Caught in a no-win situation: discussions about CCSVI between persons with multiple sclerosis and their neurologists - a qualitative study

Vascular multiple sclerosis: addressing the pathogenesis, genetics, pro-angiogenic factors, and vascular abnormalities, along with the role of vascular intervention

Dysfunction in the epithelium, breakdown of the blood-brain barrier, and consequent leukocyte and T-cell infiltration into the central nervous system define Vascular Multiple Sclerosis. Multiple sclerosis (MS) affects around 2.5 million individuals worldwide, is the leading cause of neurological impairment in young adults, and can have a variety of progressions and consequences. Despite significant discoveries in immunology and molecular biology, the root cause of MS is still not fully understood, as do the immunological triggers and causative pathways. Recent research into vascular anomalies associated with MS suggests that a vascular component may be pivotal to the etiology of MS, and there can be actually a completely new entity in the already available classification of MS, which can be called 'vascular multiple sclerosis'. Unlike the usual other causes of MS, vascular MS is not dependent on autoimmune pathophysiologic mechanisms, instead, it is caused due to the blood vessels pathology. This review aims to thoroughly analyze existing information and updates about the scattered available findings of genetics, pro-angiogenetic factors, and vascular abnormalities in this important spectrum, the vascular facets of MS.

Communication between persons with multiple sclerosis and their health care providers: A scoping review

OBJECTIVES

This study undertakes a scoping review of research about communication between persons with MS and their health care providers.

DESIGN

PubMed, PsycInfo, Communication Source, Socindex, Sociological Abstracts, Cinahl, and Proquest Dissertations and Theses were used to identify studies since each database's inception. Research team members engaged in study selection, coding for communication issues, and data extraction for descriptive information.

RESULTS

Of the 419 empirical articles identified, 175 were included. Codes represented all elements of ecological and pathway models, emphasizing emerging technologies for facilitating communication, uncertainty and anxiety for persons with MS, and communication issues surrounding diagnosis, information seeking, and decision making.

CONCLUSION

This review synthesizes and organizes influences on communication, communication processes, and health outcomes of communication for persons with MS and their providers. Findings extend the ecological model with illness context and the pathway model with communication breakdowns and provider outcomes.

PRACTICE IMPLICATIONS

Health care providers should consider the complexity of communication when interacting with persons with MS, including the larger context in which it occurs, communication processes and their purposes, and short-term and long-term consequences of interactions. Ecological and pathway models can be frameworks for developing educational materials, as they succinctly capture key communication issues and outcomes.

“I wanna live and not think about the future” what place for advance care planning for people living with severe multiple sclerosis and their families? A qualitative study

Background

Little is known about how people with multiple sclerosis (MS) and their families comprehend advance care planning (ACP) and its relevance in their lives.

Aim

To explore under what situations, with whom, how, and why do people with MS and their families engage in ACP.

Methods

We conducted a qualitative study comprising interviews with people living with MS and their families followed by an ethical discussion group with five health professionals representing specialties working with people affected by MS and their families. Twenty-seven people with MS and 17 family members were interviewed between June 2019 and March 2020. Interviews and the ethical discussion group were audio-recorded and transcribed verbatim. Data were analysed using the framework approach.

Results

Participants’ narratives focused on three major themes: (i) planning for an uncertain future; (ii) perceived obstacles to engaging in ACP that included uncertainty concerning MS disease progression, negative previous experiences of ACP discussions and prioritising symptom management over future planning; (iii) Preferences for engagement in ACP included a trusting relationship with a health professional and that information then be shared across services. Health professionals’ accounts from the ethical discussion group departed from viewing ACP as a formal document to that of an ongoing process of seeking preferences and values. They voiced similar concerns to people with MS about uncertainty and when to initiate ACP-related discussions. Some shared concerns of their lack of confidence when having these discussions.

Conclusion

These findings support the need for a whole system strategic approach where information about the potential benefits of ACP in all its forms can be shared with people with MS. Moreover, they highlight the need for health professionals to be skilled and trained in engaging in ACP discussions and where information is contemporaneously and seamlessly shared across services.

"I Will Respect the Autonomy of My Patient": A Scoping Review of Shared Decision Making in Multiple Sclerosis

Background

Patient autonomy is a bioethical principle that was strengthened in the revised Declaration of Geneva. Shared decision making (SDM) is particularly relevant in the management of multiple sclerosis (MS) because many preference-sensitive decisions have to be made during the disease course. We aimed to summarize the available evidence on SDM in the MS field and to inform future research and practice.

Methods

We performed a scoping review by searching MEDLINE (past 5 years). Studies were included if they reported primary/secondary research and focused on SDM related to people with MS. Data were grouped into topics, with results presented in narrative form.

Results

From 865 references, we included 55 studies conducted mostly in Europe. Half of the studies were observational, followed by qualitative (20%), mixed-methods (17%), randomized controlled trials (RCTs, 5%), quasi-experimental (5%), and reviews (4%). Most studies addressed people with relapsing-remitting MS (85%); the remaining addressed health care professionals, patients' significant others, or a combination. We identified five main topics: decisions on disease-modifying drugs, decisions on chronic cerebrospinal venous insufficiency treatment, information provision and patient education, health literacy, and risk knowledge.

Conclusions

The high proportion of included studies on SDM in MS in Europe suggests an earlier adoption of these concepts in this area. Decisions on disease-modifying drugs was the prevalent topic. Only 5% of studies were RCTs, indicating that more research is needed to study the effectiveness of SDM interventions. Studies addressing people with primary and secondary progressive MS are also needed.

A realist review of advance care planning for people with multiple sclerosis and their families

Background

Advance care planning (ACP) is reported to improve the quality of outcomes of care among those with life-limiting conditions. However, uptake is low among people living with multiple sclerosis (MS) and little is known about why or how people with MS engage in this process of decision-making.

Aims

To develop and refine an initial theory on engagement in ACP for people with MS and to identify ways to improve its uptake for those who desire it.

Methods

Realist review following published protocol and reporting following Realist and Meta-narrative Evidence Synthesis: Evolving Standards (RAMESES) guidelines. A multi-disciplinary team searched MEDLINE, PsychInfo, CINAHL, Scopus, Web of Science, Embase, Google Scholar in addition to other sources from inception to August 2019. Quantitative or qualitative studies, case reports, and opinion or discussion articles related to ACP and/or end of life discussions in the context of MS were included, as well as one article on physical disability and one on motor neuron disease, that contributed important contextual information. Researchers independently screened abstracts and extracted data from full-text articles. Using abductive and retroductive analysis, each article was examined for evidence to support or refute ‘context, mechanism, and outcome’ (CMO) hypotheses, using the Integrated Behaviour Model to guide theory development. Quality was assessed according to methodological rigour and relevance of evidence. Those studies providing rich descriptions were synthesised using a realist matrix to identify commonalities across CMO configurations.

Results

Of the 4,034 articles identified, 33 articles were included in the synthesis that supported six CMO hypotheses that identified contexts and mechanisms underpinning engagement in ACP for people with MS and included: acceptance of their situation, prior experiences, confidence, empowerment, fear (of being a burden, of death and of dying) and the desire for autonomy. Acceptance of self as a person with a life-limiting illness was imperative as it enabled people with MS to see ACP as pertinent to them. We identified the context of MS—its long, uncertain disease trajectory with periods of stability punctuated by crisis—inhibited triggering of mechanisms. Similarly, the absence of skills and confidence in advanced communication skills among health professionals prevented possibilities for ACP discussions taking place.

Conclusion

Although mechanisms are inhibited by the context of MS, health professionals can facilitate greater uptake of ACP among those people with MS who want it by developing their skills in communication, building trusting relationships, sharing accurate prognostic information and sensitively discussing death and dying.

Percutaneous transluminal angioplasty for treatment of chronic cerebrospinal venous insufficiency (CCSVI) in people with multiple sclerosis

BACKGROUND

Multiple sclerosis (MS) is a leading cause of neurological disability in young adults. The most widely accepted hypothesis regarding its pathogenesis is that it is an immune-mediated disease. It has been hypothesised that intraluminal defects, compression, or hypoplasia in the internal jugular or azygos veins may be important factors in the pathogenesis of MS. This condition has been named 'chronic cerebrospinal venous insufficiency' (CCSVI). It has been suggested that these intraluminal defects restrict the normal blood flow from the brain and spinal cord, causing the deposition of iron in the brain and the eventual triggering of an auto-immune response. The proposed treatment for CCSVI is venous percutaneous transluminal angioplasty (PTA), which is claimed to improve the blood flow in the brain thereby alleviating some of the symptoms of MS. This is an update of a review first published in 2012.

OBJECTIVES

To assess the benefit and safety of venous PTA in people with MS and CCSVI.

SEARCH METHODS

We searched the Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Group's Specialised Register up to 30 August 2018, CENTRAL (in the Cochrane Library 2018, issue 8), MEDLINE up to 30 August 2018, Embase up to 30 August 2018, metaRegister of Controlled Trials, ClinicalTrials.gov., the Australian New Zealand Clinical Trials Registry, and the World Health Organization (WHO) International Clinical Trials Registry platform. We examined the bibliographies of the included and excluded studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) in which PTA and sham interventions were compared in adults with MS and CCSVI.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed study eligibility and risk of bias, and extracted data. We reported results as risk ratios (RR) with 95% confidence intervals (CI). We performed statistical analyses using the random-effects model; and we assessed the certainty of the evidence using GRADE.

MAIN RESULTS

We included three RCTs (238 participants) in this update. One hundred and thirty-four participants were randomised to PTA and 104 to sham treatment. We attributed low risk of bias to two (67%) studies for sequence generation and two (67%) studies for performance bias. All studies were at a low risk of detection bias, attrition bias, reporting bias and other potential sources of bias.There was moderate-quality evidence to suggest that venous PTA did not increase the proportion of patients who had operative or post-operative serious adverse events compared with the sham procedure (RR 3.33, 95% CI 0.36 to 30.44; 3 studies, 238 participants); nor did it increase the proportion of patients who improved on a functional composite measure including walking control, balance, manual dexterity, postvoid residual urine volume, and visual acuity over 12-month follow-up (RR 0.84, 95% CI 0.55 to 1.30; 1 study, 110 participants); nor did it reduce the proportion of patients who experienced new relapses at six- or 12-month follow-up (RR 0.87, 95% CI 0.51 to 1.49; 3 studies, 235 participants). There was no effect of venous PTA on disability worsening measured by the Expanded Disability Status Scale, which was reported at follow-up intervals of six months (one study), 11 months (one study) and 12 months (one study). Quality of life was reported in two studies with no difference between treatment groups. Moderate or severe pain during or post venography was reported in both PTA and sham-procedure participants in all included studies. Venous PTA was not effective in restoring blood flow assessed at one-month (one study) or 12-month follow-up (one study).

AUTHORS' CONCLUSIONS

This systematic review identified moderate-quality evidence that, compared with sham procedure, venous PTA intervention did not provide benefit on patient-centred outcomes (disability, physical or cognitive functions, relapses, quality of life) in people with MS. Venous PTA has proven to be a safe technique but in view of the available evidence of its ineffectiveness, this intervention cannot be recommended in people with MS. All ongoing trials were withdrawn or terminated and hence this updated review is conclusive. No further randomised clinical studies are needed.
