Assessing the Usability of an Instagram Filter in Monitoring Essential Tremor: A Proof-of-Concept Study.

Background: Spiral drawing is an important test in monitoring essential tremor (ET). With the rise of telemedicine amid the coronavirus disease 2019 pandemic, a contactless tool for monitoring tremors was required. We aimed to assess the validity of a novel smartphone technology using a video-based social media platform for rapid and objective monitoring of ET. Methods: A prospective pilot study evaluated patients with ET in 2 clinic visits. Videos of tremors were recorded using a publicly available Instagram filter and were visually compared with spirals drawn by the patients. The level of agreement among the raters was evaluated. Results: A total of 12 patients with ET were recruited. A consensus between both raters was achieved for 11 patients (91.6%) for both spirals and videos with good interrater agreement (κ value, 0.755 ± 0.332). Conclusion: This novel method was found to be valid and easy to use in measuring ET in real-world settings. Further research in a larger cohort is needed to suggest its use as a home-based or clinic-based monitoring tool.

Quality of life among health care workers in Arab countries 2 years after COVID-19 pandemic.

Background: Assessment of the quality of life (QoL) among healthcare workers (HCWs) is vital for better healthcare and is an essential indicator for competent health service delivery. Since the coronavirus disease 2019 (COVID-19) pandemic strike, the frontline position of HCWs subjected them to tremendous mental and psychological burden with a high risk of virus acquisition. Aim: This study evaluated the QoL and its influencing factors among HCWs residing in the Arab countries. Methods: This was a cross-sectional study using a self-administered online questionnaire based on the World Health Organization QoL-BREF instrument with additional questions related to COVID-19. The study was conducted in three different languages (Arabic, English, and French) across 19 Arab countries between February 22 and March 24, 2022. Results: A total of 3,170 HCWs were included in the survey. The majority were females (75.3%), aged 18-40 years (76.4%), urban residents (90.4%), married (54.5%), and were living in middle-income countries (72.0%). The mean scores of general health and general QoL were 3.7 ± 1.0 and 3.7 ± 0.9, respectively. Those who attained average physical, psychological, social, and environmental QoL were 40.8, 15.4, 26.2, and 22.3%, respectively. The income per capita and country income affected the mean scores of all QoL domains. Previous COVID-19 infection, having relatives who died of COVID-19, and being vaccinated against COVID-19 significantly affected the mean scores of different domains. Conclusion: A large proportion of the Arab HCWs evaluated in this study had an overall poor QoL. More attention should be directed to this vulnerable group to ensure their productivity and service provision.

Acceptance of COVID-19 Vaccine Booster Doses Using the Health Belief Model: A Cross-Sectional Study in Low-Middle- and High-Income Countries of the East Mediterranean Region.

Coronavirus disease (COVID-19) booster doses decrease infection transmission and disease severity. This study aimed to assess the acceptance of COVID-19 vaccine booster doses in low, middle, and high-income countries of the East Mediterranean Region (EMR) and its determinants using the health belief model (HBM). In addition, we aimed to identify the causes of booster dose rejection and the main source of information about vaccination. Using the snowball and convince sampling technique, a bilingual, self-administered, anonymous questionnaire was used to collect the data from 14 EMR countries through different social media platforms. Logistic regression analysis was used to estimate the key determinants that predict vaccination acceptance among respondents. Overall, 2327 participants responded to the questionnaire. In total, 1468 received compulsory doses of vaccination. Of them, 739 (50.3%) received booster doses and 387 (26.4%) were willing to get the COVID-19 vaccine booster doses. Vaccine booster dose acceptance rates in low, middle, and high-income countries were 73.4%, 67.9%, and 83.0%, respectively (p < 0.001). Participants who reported reliance on information about the COVID-19 vaccination from the Ministry of Health websites were more willing to accept booster doses (79.3% vs. 66.6%, p < 0.001). The leading causes behind booster dose rejection were the beliefs that booster doses have no benefit (48.35%) and have severe side effects (25.6%). Determinants of booster dose acceptance were age (odds ratio (OR) = 1.02, 95% confidence interval (CI): 1.01-1.03, p = 0.002), information provided by the Ministry of Health (OR = 3.40, 95% CI: 1.79-6.49, p = 0.015), perceived susceptibility to COVID-19 infection (OR = 1.88, 95% CI: 1.21-2.93, p = 0.005), perceived severity of COVID-19 (OR = 2.08, 95% CI: 137-3.16, p = 0.001), and perceived risk of side effects (OR = 0.25, 95% CI: 0.19-0.34, p < 0.001). Booster dose acceptance in EMR is relatively high. Interventions based on HBM may provide useful directions for policymakers to enhance the population's acceptance of booster vaccination.

A systematic review of cases of CNS demyelination following COVID-19 vaccination.

BACKGROUND: Since the emergency use approval of different types of COVID-19 vaccines, several safety concerns have been raised regarding its early and delayed impact on the nervous system. OBJECTIVE: This study aims to systematically review the reported cases of CNS demyelination in association with COVID-19 vaccination, which has not been performed, to our knowledge. METHODS: A systematic review was performed by screening published articles and preprints of cases of CNS demyelination in association with COVID-19 vaccines in PubMed, SCOPUS, EMBASE, Google Scholar, Ovid and medRxiv databases, until September 30, 2021. This study followed PRISMA guidelines. Descriptive findings of reported cases were reviewed and stratified by demographic and clinical findings, diagnostic work-up, management, and overall outcome. RESULTS: A total of 32 cases were identified, with female predominance (68.8%) and median age of 44 years. Eleven cases were reported after Pfizer vaccine, 8 following AstraZeneca vaccine, 6 following Moderna, 5 following Sinovac/ Sinopharm vaccines, and one following each of Sputnik and Johnson&Johnson vaccines. The majority of cases (71.8%) occurred after the first dose of the vaccine, with neurological symptoms manifesting after a median of 9 days. The most common reported presentations were transverse myelitis (12/32) and MS-like pictures (first diagnosis or a relapse) in another 12/32 cases, followed by ADEM- like (5/32), and NMOSD- like (3/32) presentations. History of a previous immune-mediated disease was reported in 17/32 (53.1%) cases. The mRNA-based vaccines resulted in the greatest number of demyelinating syndromes (17/32), followed by viral vector vaccines (10/32), and inactivated vaccines (5/32). Most MS-like episodes (9/12) were triggered by mRNA-based vaccines, while TM occurred following both viral vector and mRNA-based vaccines. Management included high dose methylprednisolone, PLEX, IVIg, or a combination of those, with a favorable outcome in the majority of case; marked/complete improvement (25/32) or stabilized/ partial recovery in the remaining cases. CONCLUSION: This systematic review identified few cases of CNS demyelination following all types of approved COVID-19 vaccines so far. Clinical presentation was heterogenous, mainly following the first dose, however, half of the reported cases had a history of immune-mediated disease. Favorable outcome was observed in most cases. We suggest long-term post-marketing surveillance for these cases, to assess for causality, and ensure the safety of COVID-19 vaccines.

Association of CNS demyelination and COVID-19 infection: an updated systematic review.

BACKGROUND: Since the declaration of COVID-19 pandemic, several case reports of demyelination of both peripheral and central nervous systems have been published. The association between CNS demyelination and viral infection has long been documented, and this link was recently reported following SARS-CoV-2 infection as well. OBJECTIVES: In this systematic review, we aim to investigate the existing literature on CNS demyelination associated with SARS-CoV-2, and the proposed pathophysiological mechanisms. METHODS: We conducted a systematic review of articles in PubMed, SCOPUS, EMBASE, Cochrane, Google Scholar and Ovid databases, from 1 January 2020 until June 15, 2021. The following keywords were used: "COVID-19", "SARS-CoV-2", "demyelination", "demyelinating disease", "multiple sclerosis", "neuromyelitis optica", and "transverse myelitis". RESULTS: A total of 60 articles were included in the final analysis of this systematic review and included 102 patients: 52 (51%) men and 50 (49%) women, with a median age of 46.5 years. The demyelination mimicked a variety of conditions with a picture of encephalitis/encephalomyelitis being the most common. At the same time other patterns were less frequently reported such as MS, NMOSD and even MOGAD. Longitudinally extensive transverse myelitis (LETM) was the most frequently reported pattern of spinal cord involvement. CONCLUSION: A growing body of literature has shown an association between SARS-CoV-2 infection and the development of different types of CNS demyelination. Although causality cannot readily be inferred, this review may suggest a probable causal relationship, through a para-infectious or post-infectious immune-mediated etiology in COVID-19 patients. This relationship needs to be clarified in future research.

A case report of multiple sclerosis after COVID-19 infection: causality or coincidence?

Introduction Since the declaration of COVID-19 pandemic, several cases of demyelination of both peripheral and central nervous systems have been reported. The association of viral infection and the development of CNS demyelination has long been studied, and this link has recently been reported following SARS-CoV-2 infection as well. Case report We report a case of a 36-year-old male who developed CNS demyelinating disease, that fulfilled the diagnostic criteria of multiple sclerosis (MS), 2 months after laboratory-confirmed infection with SARS-CoV-2. Conclusion To our knowledge, this is the second published case report of MS in association with COVID-19 infection, and the first case from Middle East and North Africa (MENA) region, adding to the growing literature of a probable causal relationship between SARS‐CoV‐2 infection and the development of MS.

Unexplained worsening of parkinsonian symptoms in a patient with advanced Parkinson's disease as the sole initial presentation of COVID-19 infection: a case report.

BACKGROUND: Parkinson's disease (PD) is a neurodegenerative condition that has been reported following viral infections in rare occasions. Several neurological complications have emerged in association with coronavirus disease 2019 (COVID-19), since its declaration as a pandemic. Herein, we present a novel case of unexplained worsening of PD as the sole initial presentation of COVID-19, in the absence of fever or respiratory symptoms. CASE PRESENTATION: A 56-year-old male with advanced PD presented with severe rigidity, dystonic posturing of both feet, and confusion of 4 days duration. His condition progressed to an akinetic-rigid state and confusion during the following week, and a routine nasopharyngeal swab tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the 9th day of onset. He developed fever and dyspnea later and was intubated on the 10th day. CONCLUSION: To our knowledge, worsening of PD symptoms as the sole initial manifestation of SARS-CoV-2 infection, in the absence of other cardinal features of COVID-19, has not been reported in the literature. We suggest testing for COVID-19 infection in patients with PD, especially advanced cases, who present with unexplained worsening of symptoms, even in the absence of COVID-19 cardinal features.

Physicians' attitude towards webinars and online education amid COVID-19 pandemic: When less is more.

BACKGROUND: Since the declaration of COVID-19 as a pandemic, all scientific medical activities were shifted to an online format, in the form of webinars, to maintain continuing medical education (CME). We aimed to assess physicians' attitude among different medical specialties towards this sudden and unexpected shift of traditional face-to-face meetings into webinars, and to suggest future recommendations. METHODS: We conducted a cross-sectional, internet-based survey study using a 25-item questionnaire, from November 1 and November 15, 2020. The survey was created and distributed to physicians from different medical and surgical specialties and from different countries via several social media platforms, using a snowball technique. RESULTS: A total of 326 physicians responded; 165 (50.6%) were females, mean age of responders was 38.7 ± 7.5 years. The majority of responses (93.2%) came from Arab countries. Of them, 195 (59.8%) reported attending more webinars compared to the same period last year, with average of 3 per month. As regard to the general impression; 244 (74.8%) were "strongly satisfied" or "satisfied", with the most satisfaction for "training courses: by 268 (82.2%), and "International conferences" by 218 (66.9%). However, 246 respondents (75.5%) felt overwhelmed with the number and frequency of webinars during the pandemic, 171 (52.5%) reported attending less than 25% of webinars they are invited to, 205 (62.8%) disagreed that webinars can replace in-person meetings after the pandemic, and 239 (73.3%) agreed that online meetings need proper regulations. CONCLUSIONS: Webinars comprised a major avenue for education during COVID-19 pandemic, with initial general satisfaction among physicians. However, this paradigm shift was sudden and lacked proper regulations. Despite initial satisfaction, the majority of physicians felt overwhelmed with the number and frequency of webinars. Physicians' satisfaction is crucial in planning future educational activities, and considering that this current crisis will most likely have long lasting effects, webinars should be viewed as complementing traditional in-person methods, rather than replacement. In this study, we are suggesting recommendations to help future regulation of this change.

Association of COVID-19 Pandemic and Rate of Cognitive Decline in Patients with Dementia and Mild Cognitive Impairment: A Cross-sectional Study.

Introduction: Since the declaration of coronavirus disease 2019 (COVID-19) as a pandemic, patients with dementia, were specifically vulnerable to the negative impact of the outbreak. Objective: To examine the association between lockdown amid COVID-19 pandemic and the rate of cognitive decline among patients with dementia and mild cognitive impairment (MCI). Methods: We conducted a cross-sectional observational study on patients with dementia and MCI who attended the outpatient clinic at Ibn Sina Hospital, the main tertiary neurology center in Kuwait, during the month of September 2020. The rate of cognitive decline, estimated by MMSE scores, was compared between the period prior to, and during lockdown. Results: We evaluated 36 consecutive patients with cognitive impairment (23 females [63.9%], mean age 71 ± 10.8 years, mean disease duration 34.6 ± 29 months). Eleven patients (30.6%) progressed to a more severe stage during the study period; 1 MCI (2.8%) converted to mild dementia, 6 (16.6%) mild to moderate, and 4 (11.1%) moderate to severe dementia. Monthly decline of MMSE scores before lockdown was 0.2 ± 0.1 points, while it was 0.53 ± 0.3 points during lockdown, which was statistically significant (p = .001). The most affected cognitive domain was the memory with a mean decline of 1.5 ± 0.8 points. Conclusions: This study provides "real-world" data suggesting rapid cognitive decline in patients with dementia during the lockdown period. Healthcare systems should pay more attention to this vulnerable group, to help them maintain their mental, physical and social well-being during this crisis.

Impact of coronavirus disease 2019 (COVID-19) pandemic on patients with migraine: a web-based survey study.

BACKGROUND: Since the declaration COVID-19 as a pandemic, healthcare systems around the world have faced a huge challenge in managing patients with chronic diseases. Patients with migraine were specifically vulnerable to inadequate medical care. We aimed to investigate the "real-world" impact of COVID-19 pandemic on migraine patients, and to identify risk factors for poor outcome. METHODS: We administered an online, self-reported survey that included demographic, migraine-related, COVID-19-specific and overall psychosocial variables between July 15 and July 30, 2020. We recruited a sample of patients with migraine from headache clinic registry and via social media to complete an anonymous survey. Outcomes included demographic variables, change in migraine frequency and severity during the lockdown period, communication with treating physician, compliance to migraine treatment, difficulty in getting medications, medication overuse, symptoms of anxiety and/or depression, sleep and eating habits disturbance, screen time exposure, work during pandemic, use of traditional medicine, effect of Botox injection cancellation, and overall worries and concerns during pandemic. RESULTS: A total of 1018 patients completed the survey. Of the respondents, 859 (84.3%) were females; 733 (71.9%) were aged 20 to 40 years, 630 (61.8%) were married, and 466 (45.7%) reported working during the pandemic. In comparison to pre-pandemic period, 607 respondents (59.6%) reported increase in migraine frequency, 163 (16%) reported decrease in frequency, and 105 (10.3%) transformed to chronic migraine. Severity was reported to increase by 653 (64.1%) respondents. The majority of respondents; 626 (61.5%) did not communicate with their neurologists, 477 (46.9%) reported compliance to treatment, and 597 (58.7%) reported overuse of analgesics. Botox injections cancellation had a negative impact on 150 respondents (66.1%) from those receiving it. Forty-one respondents (4%) were infected with COVID-19; 26 (63.4%) reported worsening of their headaches amid infection period. Sleep disturbance was reported by 794 (78.1%) of respondents, and 809 (79.5%) reported having symptoms of anxiety and/or depression. CONCLUSIONS AND RELEVANCE: COVID-19 pandemic had an overall negative impact on patients with migraine. Several risk factors for poor outcome were identified. Long-term strategies should be validated and implemented to deliver quality care for patients with migraine, with emphasis on psychosocial well-being.
