ABSTRACT: Background
As cannabis products become increasingly accessible across the United States, it is important to understand the contemporary use of cannabis for managing multiple sclerosis (MS) symptoms.Methods
We invited participants with MS from the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry (aged 18 years or older) to complete a supplemental survey on cannabis use between March and April 2020. Participants reported cannabis use, treated symptoms, patterns, preferences, methods of use, and the factors limiting use. Findings are reported using descriptive statistics.Results
Of the 6934 participants invited, 3249 responded. Of the respondents, 31% reported having ever used cannabis to treat MS symptoms, with 20% currently using cannabis. The remaining 69% had never used cannabis for MS symptoms, for reasons including not enough data about efficacy (40%) and safety (27%), and concerns about legality (25%) and cost (18%). The most common symptoms current users were attempting to treat were spasticity (80%), pain (69%), and sleep problems (61%). Ever users (vs never users) were more likely to be younger, be non-White, have lower education, reside in the Northeast and West, be unemployed, be younger at symptom onset, be currently smoking, and have higher levels of disability and MS-related symptoms (all P < .001).Conclusions
Despite concerns about insufficient safety and efficacy data, legality, and cost, almost one-third of NARCOMS Registry respondents report having tried nonprescription cannabis products in an attempt to alleviate their symptoms. Given the lack of efficacy and safety data on such products, future research in this area is warranted.

Project description:ObjectiveThe objective of this study was to characterize the use of cannabis-based products (CBPs) by multiple sclerosis (MS) patients who attend the University of British Columbia Hospital (UBCH) MS clinic.MethodsAll patients attending the UBCH MS clinic from January to March 2018 were invited to participate in an anonymous survey that included: patient demographics (sex, age and employment status), self-reported MS-specific data (subtype, disease duration, previous and current disease modifying therapies, symptomatic medications) and CBP use (formulation, frequency, perceived benefits/side-effects). A second cohort of retrospective patient data (CBP use, sex, age, disease subtype and Expanded Disability Status Scale) was extracted from the UBCH MS clinic electronic medical record (EMR).ResultsOf 600 surveys distributed, 188 were returned with completed CBP usage. CBP use was daily for 19% (n = 37), weekly for 6% (n = 11), monthly for 4% (n = 7), rarely for 21% (n = 39) and 50% (n = 94) never used. Of the CBP users (daily, weekly and monthly), CBP use included: oral (n = 43/55), smoked/vaporized (n = 42/55), topical (n = 14/55) and mucosal (n = 5/55). EMR data was available for 561 MS patients where cannabis use/non-use was documented. CBP users represented 19% (107/561).ConclusionsCBP use is common based on volunteer reporting, with approximately one out of four patients who attend the UBCH MS clinic using CBPs.

Project description:BackgroundIndividuals with multiple sclerosis (MS) report barriers to accessing care, including receipt of preventive services. Potentially preventable hospitalization (PPH) is an important marker for access to, and receipt of timely care. However, few national studies have examined PPH risk in people with MS or considered the role of preventive care in reducing PPH risk among this patient population. Our objective was to examine PPH risk among adults with MS compared with their counterparts without MS.MethodsOptum® Clinformatics® Data Mart (2007-2017) was used to identify 6198 individuals with an MS diagnosis and their propensity-score matched counterparts without MS. Diagnostic and procedural codes were used to identify the presence of preventive hospitalizations, which were defined as quality indicators by the Agency for Healthcare Research and Quality (AHRQ) during the 4-year follow-up period since the diagnosis of MS. Information on receipt of preventive services and office visits was also extracted. Adjusted generalized estimating equations were used to examine the association between MS diagnosis and PPHs. To examine the role of preventive services on odds of PPH amongst people with MS, we reported the adjusted marginal odds ratio (OR) and 95% confidence intervals (CI).ResultsThe rate of any PPH among people with MS was double that of those without MS (131.6 vs 62.5 per 10,000). We identified higher odds of specific PPH indicators among people with MS compared to those without. Individuals with MS had 65% higher odds of hospitalization for pneumonia (OR=1.65, 95% CI: 1.01, 2.30), with similar significant findings observed for urinary tract infections (OR=4.90, 95% CI: 2.51, 9.57). In MS patients, receipt of preventive services, namely cholesterol screening (OR=0.76, 95% CI: 0.60, 0.95) and annual wellness visits were associated with lower odds of any PPH (OR=0.57, 95% CI: 0.43, 0.76).ConclusionPeople with MS were at a higher risk for PPHs compared with their counterparts without MS. Use of appropriate preventive services reduced the risk of PPH among the general population and among those with MS. More efforts are needed to encourage and facilitate the use of preventive care among people with MS. Receipt of timely and appropriate preventive care in this population may reduce the risk for PPH.

Project description:BackgroundAs the peak prevalence of multiple sclerosis (MS) shifts due to an aging patient population, understanding the characteristics that define this older cohort to improve overall management is critical. We sought to determine the clinical characteristics of people with MS over age 60.MethodsDemographics, clinical characteristics, MS disease history, and Multiple Sclerosis Performance Test (MSPT) patient-reported outcomes and neuroperformance tests (NPTs) were collected from 10 academic MS centers in the US and Europe participating in the MS Partners Advancing Technology Health Solutions (MS PATHS) system. We characterized demographic and disease characteristics of included participants using descriptive statistics. We characterized prevalence of comorbidities and compared with estimated prevalences from the National Health and Nutrition Examination Survey (NHANES) respondents aged ≥60 years in 2017-2018.ResultsWe identified 2738 individuals over age 60 from MS PATHS, with 58.1% relapsing-remitting (RR) and 41.9% progressive. Our results showed median age (RR=65.7 years, progressive=66.0 years), age of symptom onset (RR and progressive=40.9 years), and disease duration (RR=22.8 years, progressive=23.3 years). Over two-thirds of individuals in our cohort were treated with DMTs. The most common DMT used in RR patients were interferons (17.6%) and glatiramer acetate (16.3%), while glatiramer acetate was the most common (12.0%) in progressive patients. Progressive patients had higher disability (higher median PDDS scores, worse Neuro-Qol T-scores, and worse NPTs) compared to the RR group. Pain was the most common comorbidity, followed by cardiac disease, depression, hypertension, dyslipidemia, and obesity. Compared to older NHANES participants, older people with MS were more likely to have depression (MS PATHS: 51.5% [95% CI: 49.5% to 53.5%] vs. NHANES: 21.7% [95% CI: 1619.3% to 22.2%]) and osteoporosis (MS PATHS: 12.7% [95% CI: 11.3% to 14.1%] vs. NHANES: 8.2% [95% CI: 6.2% to 10.3%]); they were less likely to be obese (MS PATHS: 29.4% [95% CI: 27.7% to 31.2%] vs. NHANES: 45.1% [95% CI: 38.9% to 51.3%]) and have diabetes (MS PATHS: 12.3% [95% CI: 11.1% to 13.6%] vs. NHANES: 22.5% [95% CI: 18.8% to 25.7%]).ConclusionsOur study characterizes a large multi-center international cohort of people with MS over age 60. This contemporary cohort appears less disabled than prior studies, which may reflect long term impact of DMT availability on the natural history of MS. The burden of comorbidity in this population was generally high. Information on DMT use, comorbidity, and disability outcome measures will be beneficial in future studies evaluating the impact of therapeutic interventions in older individuals.

Project description:Cannabinoids affect immune responses in ways that may be beneficial for autoimmune diseases. We sought to determine whether chronic Cannabis use differentially modulates a select number of immune parameters in healthy controls and individuals with multiple sclerosis (MS cases). Subjects were enrolled and consented to a single blood draw, matched for age and BMI. We measured monocyte migration isolated from each subject, as well as plasma levels of endocannabinoids and cytokines. Cases met definition of MS by international diagnostic criteria. Monocyte cell migration measured in control subjects and individuals with MS was similarly inhibited by a set ratio of phytocannabinoids. The plasma levels of CCL2 and IL17 were reduced in non-naïve cannabis users irrespective of the cohorts. We detected a significant increase in the endocannabinoid arachidonoylethanolamine (AEA) in serum from individuals with MS compared to control subjects, and no significant difference in levels of other endocannabinoids and signaling lipids irrespective of Cannabis use. Chronic Cannabis use may affect the immune response to similar extent in individuals with MS and control subjects through the ability of phytocannabinoids to reduce both monocyte migration and cytokine levels in serum. From a panel of signaling lipids, only the levels of AEA are increased in individuals with MS, irrespective of Cannabis use or not. Our results suggest that both MS cases and controls respond similarly to chronic Cannabis use with respect to the immune parameters measured in this study.

Project description:BackgroundThere is a paucity of information regarding cannabis use behaviors in adult community-based athletes as most research in athletes has focused on misuse of cannabis in elite, adolescent, university-based athletes. We aimed to determine whether age related differences exist in patterns of cannabis use and subjective effects to cannabis in adult athletes.MethodsThe Athlete PEACE Survey used mainly social media and email blasts to recruit and SurveyGizmo to collect data. Cannabis patterns of use (duration of use, frequency of use, routes of administration, cannabinoid used, concurrent use with exercise), benefits, and adverse effects were reported. Age was reported by decade from 21 to ≥60. Age trends in cannabis use patterns and subjective effects were assessed using linear trend analysis.ResultsOf the 1161 participants, 301 (26%) athletes currently used cannabis. Younger athletes compared to older athletes reported significantly more positive and adverse subjective effects to cannabis, used cannabis longer, and used both tetrahydrocannabinol and cannabidiol for medical and recreational purposes. Younger athletes used cannabis concurrently with exercise more often than older athletes and consumed edibles, vaporized, and smoked more than older athletes.ConclusionsWe found age-related cannabis patterns of use and subjective effects to cannabis. Concerns about cannabis mis-use and abuse in athletes maybe overstated with the potential benefits (improved sleep, decreased anxiety, less pain) outweighing the adverse effects (increased anxiety, increased appetite, difficulty concentrating).

Project description:BACKGROUND:Mobile health (mHealth) apps might have the potential to promote self-management of people with multiple sclerosis (MS) in everyday life. However, the uptake of MS apps remains poor, and little is known about the facilitators and barriers for their efficient utilization, such as technology acceptance. OBJECTIVE:The aim of this study was to examine the acceptance of mHealth apps for disease management in the sense of behavioral intentions to use and explore determinants of utilization among people with MS based on the Unified Theory of Acceptance and Use of Technology (UTAUT). METHODS:Participants for this Web-based cross-sectional study were recruited throughout Germany with the support of regional MS associations and self-help groups. To identify determinants of intention to use MS apps, a measure based on the UTAUT was adapted with 4 key determinants (performance expectancy, effort expectancy, social influence, and facilitating conditions) and extended by Intolerance of Uncertainty (IU) and electronic health literacy. Potential influencing effects of both MS and computer self-efficacy (C-SE) as mediators and fatigue as a moderator were analyzed using Hayes's PROCESS macro (SPSS version 3.0) for IBM SPSS version 24.0. RESULTS:A total of 98 participants (mean age 47.03 years, SD 10.17; 66/98, 67% female) with moderate fatigue levels completed the survey. Although most participants (91/98, 92%) were daily smartphone users, almost two-thirds (62/98, 63%) reported no experience with MS apps. Overall, the acceptance was moderate on average (mean 3.11, SD 1.31, minimum=1 and maximum=5), with lower scores among persons with no experience (P=.04) and higher scores among current users (P<.001). In multiple regression analysis (R2=63% variance explained), performance expectancy (beta=.41) and social influence (beta=.33) were identified as significant predictors of acceptance (all P<.001). C-SE was confirmed as a partial mediator in the relationship between IU and acceptance (indirect effect: B=-.095, 95% CI -0.227 to -0.01). Furthermore, a moderated mediation by C-SE was shown in the relationship between IU and behavioral intentions to use MS apps for low (95% CI -0.42 to -0.01) and moderate levels (95% CI -0.27 to -0.01) of fatigue. CONCLUSIONS:Overall, this exploratory pilot study indicates for the first time that positive expectations about the helpfulness for self-management purposes and social support might be important factors to be considered for improving the acceptance of MS apps among smartphone users with MS. However, given some inconsistent findings, especially regarding the role of effort expectancy and IU and self-efficacy, the conceptual model needs replication with a larger sample of people with MS, varying more in fatigue levels, and a longitudinal assessment of the actual usage of MS apps predicted by acceptance in the sense of behavioral intentions to use.

Project description:Restrictions in the access to healthcare facilities during COVID-19 pandemic have raised the need for remote monitoring of chronic medical conditions, including multiple sclerosis (MS). In order to enable the continuity of care in these circumstances, many telemedicine applications are currently tested. While physicians' preferences are commonly investigated, data regarding the patients' point of view are still lacking. We built a 37 items web-based survey exploring patients' propensity, awareness, and opinions on telemedicine with the aim to evaluate the sustainability of this approach in MS. Analysing 613 questionnaires out of 1093 that were sent to persons with MS followed at the Multiple Sclerosis Center of Tor Vergata University, Rome, we found that more than half of respondents (54%) were open to having a televisit. Propensity toward telemedicine significantly depended on having a higher income (p = 0.037), living farther from the center (p = 0.038), using computer and tablet (p = 0.010) and using the Internet for other remote activities (p < 0.001), conversely it was not influenced by any specific disease characteristics (i.e. degree of disability). The main advantages and disadvantages of televisit reported by participants were respectively saving time (70%) and impossibility to measure physical parameters (71%). Although the majority of respondents are in favour of televisit, so far this approach is restricted to those displaying better socioeconomic conditions and higher familiarity with technology. Implications of the study are that telemedicine platforms should be better tailored to patients' demands in order to spread the use of telemedicine, to enhance usability and to increase patients' adherence.

Project description:Background and purposeWe aimed to estimate the prevalence of perceived cognitive impairment (PCI) and explore its associations with lifestyle and disease characteristics in a large international cohort of people with multiple sclerosis (MS).MethodsThis study was a cross-sectional analysis. Participants rated their cognitive function over the preceding 4 weeks using four questions in a subscale within the Multiple Sclerosis Quality of Life questionnaire (MSQOL-54). These questions assessed perceived concentration, attention and memory by the patient and family/friends. Four definitions of PCI were derived, ranging from lowest to highest specificity. Associations with PCI were assessed by log-binomial regression.ResultsThe prevalence of PCI in our sample ranged from 41.0% (95% confidence interval, 39.0-43.0) using the least-specific definition to 11.6% (95% confidence interval, 10.3-12.9) using the most specific definition. A number of factors were associated with PCI, increasing in magnitude as the definition specificity increased, including positive associations for smoking and body mass index, whereas physical activity, dietary quality and use of vitamin D/omega-3 supplements were inversely associated with PCI.ConclusionsOur study reports associations between healthy lifestyle behaviours and PCI in people with MS. Although reverse causality is a potential explanation for our findings, previous studies have shown comparable associations with healthy lifestyle and MS onset and progression. Subject to external validation, these results suggest benefits realized from a healthy lifestyle in people with MS.

Project description:BackgroundPatients diagnosed as having multiple sclerosis (MS) experience a wide range of symptoms requiring pharmacologic management, and many do not achieve adequate symptom control. The purpose of this study was to evaluate the role of medical cannabis (MC) as part of a comprehensive treatment plan for patients with MS.MethodsA retrospective medical record review of 141 patients with MS receiving MC for symptom management was conducted. Data were collected for up to 4 follow-up appointments after initiation of MC. Outcomes included changes in MS symptoms, medication changes, adverse events, and changes in cognition and mobility.ResultsPatients experienced extensive MS symptom improvement after initiation of MC, with alleviation of pain (72% of patients) and spasticity (48% of patients) and improvement in sleep (40% of patients) the most common. There was a significant reduction in concomitant opioid use after initiating MC as evidenced by a significant decrease in daily morphine milligram equivalents among patients prescribed opioid analgesics (P = .01). Decreases in muscle relaxant use and benzodiazepine use did not reach significance (P > .05). The most common adverse reaction to MC was fatigue (11% of patients).ConclusionsIn many patients with MS, MC was well tolerated, eased pain and spasticity, improved sleep and other symptoms, and reduced use of concomitant opioid analgesics. Prospective studies are needed to further investigate the role of MC in the treatment of patients with MS.

Project description:Falls are a serious health concern for persons with multiple sclerosis (PwMS) who use wheelchairs or scooters as their primary mode of mobility. Unfortunately, little is known about the fall prevalence and characteristics of this large segment of the multiple sclerosis (MS) community. The purpose of this study is to determine the prevalence and circumstances of falls in wheelchair and scooter users living with MS. Forty-four PwMS were recruited from research and medical centers in the United States and Asia. Participants completed a survey focusing on prevalence of falls, frequency of injurious falls, circumstances of the fall, and various quality of life indicators. A total of 44 individuals (32 females/11 males/1 not reported) aged 27 to 82 years (mean = 58 yrs) completed the survey. Seventy-five percent (n = 33) reported falling at least once in 6 months and 48% (n = 12) of those that fell sustained an injury. The majority (87.5%) of the falls occurred inside the home. Most individuals (76.7%; n = 33) reported concerns about falling and 65.9% (n = 29) limited their activities because of their concern of falling. Falls are prevalent in wheelchair and scooter users with MS. The observations highlight the need for interventions targeting this segment of the MS community.
