Exploring Factors Associated with Falls in Multiple Sclerosis: Insights from a Scoping Review.

Multiple sclerosis (MS) is a chronic inflammatory condition that causes demyelination of the central nervous system accompanied by a wide range of symptoms. The high prevalence of falls among patients diagnosed with MS within the initial six months highlights the importance of this issue. The objective of this study is to identify factors associated with falls in MS patients in order to increase awareness and reduce the risk of falls. This scoping review used specific Mesh terms to formulate the literature search around falls and MS using Medline, Google Scholar, Scopus, and Embase search engines. English papers published between 2012 and 2022, studies with a clear definition of falls, McDonald's diagnostic criteria for MS, and those with Expanded Disability Status Scale (EDSS) or Patient Determined Disease Steps (PDDS) scores were included. Critical data from the selected articles were extracted and classified according to the different factors associated with falls in MS patients. Eighteen articles were included in this review. The most important factors associated with falls in MS patients identified were the severity and progression of the disease, mobility and balance problems, bladder dysfunction, fear of falling, fatigue, and cognitive dysfunction. In conclusion, this scoping review yielded the most common factors associated with falls in patients with MS. Study findings can be used to develop future interventions focusing on improving mobility, proprioception, and balance to decrease fall risk and injury amongst MS patients.

A 12-month prospective real-life study of opicapone efficacy and tolerability in Emirati and non-White subjects with Parkinson's disease based in United Arab Emirates.

Parkinson's disease (PD) is the second most common neurodegenerative disorder, and the condition is complicated by the emergence of wearing off/motor fluctuations with levodopa treatment after a variable period. COMT inhibitors when used as adjunct therapy to levodopa tend to smoothen out these wearing off fluctuations by enhancing delivery of levodopa and increasing its bioavailability to the brain. The study was conducted to investigate the motor and nonmotor effect, safety and tolerability of the third generation once-daily COMT inhibitor (opicapone), as add-on, adjuvant therapy to levodopa and at 6 and 12 months follow-up in a real-life cohort of consecutive Emirati and non-White PD patients. A real-life observational analysis using tolerability parameters as used previously by Rizos et al. and Shulman et al. based on clinical database of cases rat Kings College Hospital Dubai Parkinson care database. This was a prospective, single-arm follow-up clinical evaluation study that evaluated the effectiveness of opicapone 50 mg once-daily regime in 50 patients diagnosed with idiopathic neurodegenerative disorder. All patients were assessed with scales used in clinical pathway and include motor Unified Parkinson's Disease Rating Scale (UPDRS), nonmotor symptom scale (NMSS), quality of life (PDQ8) Parkinson's fatigue scale (PFS16) and King's Parkinson's Pain Scale (KIPS). Out of 50 patients treated with opicapone (72% male, mean age 66.9 years (SD 9.9, range 41-82 years) and mean duration of disease 5.7 years (SD 2.5 range (2-11), there was significant statistical improvements shown in motor function-UPDRS part 3: baseline 40.64 ± 2.7, at 6 months 32.12 ± 3.14 and after 12 months 33.72 ± 3.76. Nonmotor burden NMSS: 107.00 ± 21.86, at 6 months 100.78 ± 17.28 and 12 months 96.88 ± 16.11. Reduction in dyskinesias (UPDRS part 4): baseline 8.78 ± 1.07, at 6 months 7.4 ± 0.81 and 12 months 6.82 ± 0.75. Opicapone provides beneficial motor and nonmotor effects in Emirati and other non-White Parkinson's patients, resident in UAE, proving its efficacy across different racial groups as COMT activity may vary between races.

Incidence and prevalence of neurological disorders in the United Arab Emirates: a systematic review.

BACKGROUND/OBJECTIVES: The United Arab Emirates (UAE) is a rapidly developing country. With the increase in average life-expectancy, high rates of consanguinity, and the adoption of a Western lifestyle, the burden of neurological disorders is expected to increase over the next few decades. Despite the importance of neurological disorders, there has not been a systematic review of published studies on the epidemiology of neurological disorders in the UAE. METHODS: We searched for studies of incidence and/or prevalence of neurological disorders in the UAE published in English in MEDLINE, Google Scholar, Embase, and Scopus databases with no date restrictions up until 01 October 2023. Two authors independently assessed abstracts and full texts of possibly relevant papers, followed by data extraction from studies satisfying the eligibility criteria. RESULTS: Eight articles (N = 2067 patients) were included, half reported incidence and prevalence of multiple sclerosis, with an average crude prevalence 56/100,000 and related demyelinating disorders. Others were related to headache, meningitis, cerebral venous thrombosis, and brain tumours. CONCLUSION: There is a distinct lack of data on the epidemiology of different neurological diseases in the UAE. Large population-based studies, ideally longitudinal, are required to provide accurate and reliable estimates of the incidence and prevalence of neurological disorders to help inform healthcare capacity planning.

Clinical learning environments across two different healthcare settings using the undergraduate clinical education environment measure.

BACKGROUND: The clinical placements of our medical students are almost equally distributed across private and public sectors. This study aims to assess medical students' perceptions of their Clinical learning Environment (CLE) across these two different healthcare settings, using the Undergraduate Clinical Education Environment Measure (UCEEM). METHODS: 76 undergraduate medical students (Year 5 and 6), were invited to participate. Data were collected using an online UCEEM with additional questions related to demographics and case load exposure. The UCEEM consists of two overarching domains of experiential learning and social participation, with four subdomains of learning opportunities, preparedness, workplace interaction, and inclusion. RESULTS: 38 questionnaires were received. Of 225 responses to the individual UCEEM items, 51 (22.6%) scored a mean of ≥ 4 (range 4-4.5, representing strong areas), 31 (13.7%) scored a mean of ≤ 3 (range 2.1-3, needing attention) and 143 (63.6%) scored a mean of 3.1-3.9 (areas that could be improved). The majority (63%) of the case load exposure responses scored a mean of ≥ 4 (range 4-4.5). Compared to the private sittings, there is a significant reduction in total UCEEM (p = 0.008), preparedness for student entry (p = 0.003), and overarching dimension of social participation (p = 0.000) scores for the public sector. Similarly, both workplace interaction patterns and student inclusion and equal treatment scored significantly lower for the public sector (p = 0.000 and p = 0.011 respectively). Two out of three case load exposure items scored significantly higher for the public sector (p = 0.000). DISCUSSION: The students' CLE perceptions were generally positive. The lower UCEEM ratings in the public sector items were related to student entry preparedness, workplace interactions, student inclusiveness and workforce equity of treatment. In contrast the students were exposed to more variety and larger number of patients in the public sector. These differences indicated some significantly different learning environments between the two sectors.

Hiccups, Hypersalivation, Hallucinations in Parkinson's Disease: New Insights, Mechanisms, Pathophysiology, and Management.

Parkinson's disease (PD) is a chronic, progressive neurological disorder and the second most common neurodegenerative condition. We report three common but overlooked symptoms in PD-hiccups, hypersalivation, and hallucinations-in terms of their prevalence, pathophysiology, and up-to-date evidence-based treatment strategies. Whilst all these three symptoms do occur in many other neurological and non-neurological conditions, early recognition and treatment are paramount. Whilst hiccups affect 3% of healthy people, their rate of occurrence is higher (20%) in patients with PD. Hypersalivation (Sialorrhea) is another common neurological manifestation of many neurological and other neurodegenerative conditions such as motor neuron disease (MND), with a median prevalence rate of 56% (range: 32-74%). A 42% prevalence of sialorrhea is also reported in sub-optimally treated patients with PD. Hallucinations, especially visual hallucinations, are commonly reported, with a prevalence of 32-63% in PD, and a 55-78% prevalence is noted in patients with dementia with Lewy bodies (DLB), followed by tactile hallucinations, which are indicated by a sensation of crawling bugs or imaginary creatures across the skin surface. Whilst mainstay and primary management strategies for all these three symptoms are carried out through history taking, it is also essential to identify and treat possible potential triggers such as infection, minimise or avoid causative (such as drug-induced) factors, and especially carry out patient education before considering more definitive treatment strategies, such as botulinum toxin therapies for hypersalivation, to improve the quality of life of patients. This original review paper aims to provide a comprehensive overview of the disease mechanisms, pathophysiology, and management of hiccups, hypersalivation, and hallucinations in Parkinson's disease.

The relationship of online pre-recorded neurology mini-lectures to medical student assessment: a pilot study.

INTRODUCTION: eLearning has become an essential part of medical education. However, there is a lack of published research on student engagement with online pre-recorded mini-lectures and its relation to assessment. The aim of this pilot study is to explore the relationship between newly introduced neurology pre-recorded mini-lectures and undergraduate medical students engagement and assessment. This may encourage the wider use of mini-lectures in undergraduate medical curricula. METHODS: The engagement of medical students with 48 online pre-recorded neurology mini-lectures was assessed through a Learning Management System. To measure engagement, data was stratified according to the number of watched/downloaded mini-lectures. A point system was used (out of 5): - 1 point = watching/downloading 0-10 mini-lectures, 2 points = watching/downloading 11-20 mini-lectures, 3 points = watching/downloading 21-30 mini-lectures, 4 points = watching/downloading 31-40 mini-lectures and, 5 points = watching/downloading 41-48 mini-lectures. The students' engagement was correlated with their neurology assessments [Objective Structured Clinical Examination (OSCE), and knowledge-based assessment 10 Multiple Choice Questions (MCQs) and one 10-mark Short Answer Question, (SAQ)], internal medicine grade and annual grade point average (GPA) using the Pearson correlation coefficient. RESULTS: The mean engagement of 34, Year 5, medical students is 3.9/5. There is a significant positive correlation between engagement and internal medicine grade (r = 0.35, p = 0.044). There is a moderate correlation between engagement and neurology OSCE (r = 0.23), annual Year 5 GPA (r = 0.23), neurology knowledge-based score (r = 0.22) and composite neurology knowledge/OSCE (r = 0.27). The knowledge-based assessment included SAQ and MCQs: there was a moderate correlation with SAQ (r = 0.30), but a weak negative correlation with the MCQs (r =-0.11). Sub-groups analysis comparing the top- and low- or non- engaging students made these weaker correlations stronger. CONCLUSION: This pilot study indicates a high rate of engagement with an online pre-recorded mini-lectures resource and evidence of moderate correlation between engagement and assessment. Online pre-recorded mini-lectures should be used more in delivering the curriculum contents of the clinical clerkships. Further studies are needed to evaluate the relation and the impact of the mini-lectures on assessment.

First Two-Year Observational Exploratory Real Life Clinical Phenotyping, and Societal Impact Study of Parkinson's Disease in Emiratis and Expatriate Population of United Arab Emirates 2019-2021: The EmPark Study.

BACKGROUND: Phenotypic differences in Parkinson's Disease (PD) among locals (Emiratis) and Expatriates (Expats) living in United Arab Emirates have not been described and could be important to unravel local aspects of clinical heterogenicity of PD pointing towards genetic and epigenetic variations. OBJECTIVE: To investigate the range and nature of motor and nonmotor clinical presentations of PD and its impact on time to diagnosis, local service provisions, and quality of life in Emiratis and Expats in UAE, as well as address the presence of current unmet needs on relation to care and etiopathogenesis of PD related to possible genetic and epigenetic factors. METHODS: a cross-sectional one point in time prospective, observational real-life study of 171 patients recruited from PD and Neurology clinics across United Arab Emirates from 2019-2021. Primary outcomes were sociodemographic data, motor and nonmotor symptoms (NMS), including cognition and sleep, and quality of life (QOL) assessments, Results: A total of 171 PD patients (52 Emiratis 119 Expats) were included with mean age (Emiratis 48.5 (13.1) Expats 64.15 (13.1)) and mean disease duration (Emiratis 4.8 (3.2) Expats 6.1 (2.9)). In the Emiratis, there was a significant mean delay in initiating treatment after diagnosis (Emiratis 1.2 (0.9) Expats 1.6 (1.1)), while from a clinical phenotyping aspect, there is a high percentage of akinesia 25 (48.1) or tremor dominant (22 (42.3)) phenotypes as opposed to mixed subtype 67 (56.3) in Expat cohorts; double tremor dominant, especially Emirati females (25%), had a predominant lower limb onset PD. Both Emirati (27.9 (24.0)) and Expat 29.4 (15.6) showed moderate NMS burden and the NMS profile is dominated by Sleep, Fatigue, Mood, Emotional well-being 3.0 (1.1) and Social Stigma 3.5 (0.9) aspects of PDQ8 SI measurements are predicted worse QOL in Emiratis, while lack of social support 2.3 (1.3) impaired QOL in Expat population. Awareness for advanced therapies was low and only 25% of Emiratis were aware of deep brain surgery (DBS), compared to 69% Expats. Only 2% of Emiratis, compared to 32% of Expats, heard of Apomorphine infusion (CSAI), and no (0%) Emiratis were aware of intrajejunal levodopa infusion (IJLI), compared to 13% of expats. CONCLUSION: Our pilot data suggest clinical phenotypic differences in presentation of PD in Emiratis population of UAE compared to expats. Worryingly, the data also show delayed treatment initiation, as well as widespread lack of knowledge of advanced therapies in the Emirati population.

Factors affecting consultant attitudes to undertaking undergraduate medical student teaching in the UK: a systematic review.

OBJECTIVE: This systematic review aimed to explore consultant attitudes towards teaching undergraduate medical students in the UK. DESIGN: Systematic review. METHODOLOGY: Standard systematic review methodology was followed. MEDLINE, EMBASE and OpenGrey were searched from inception to August 2019 to identify studies exploring senior doctors' attitudes towards teaching undergraduate medical students. Two reviewers independently carried out key methodological steps including study screening/selection, quality assessment and data extraction. A narrative synthesis was undertaken. RESULTS: Five studies were included in the review dating 2003-2015. Two studies used questionnaires, and three used focus groups/semistructured interviews. Key findings identified across all studies were consultants generally found teaching undergraduate medical students enjoyable, and consultants identified time constraints as a barrier to teaching. Other findings were consultants feeling there was a lack of recognition for time spent teaching, and a lack of training/guidance regarding teaching students. CONCLUSIONS: This is the first systematic review to explore senior hospital doctors' attitudes towards teaching undergraduate medical students. Despite these five studies spanning 12 years, the same attitudes and issues regarding teaching are identified by all, suggesting lack of time particularly is a persistent problem regarding consultant-based teaching. An anecdotal impression is that consultants are no longer as enthusiastic about teaching as they once were, but it is evident over the 12 years of these studies that enjoyment levels, and presumably enthusiasm, have not changed significantly.

Parkinson's Disease in the Gulf Countries: An Updated Review.

BACKGROUND: The Arabian Gulf region is a rapidly developing part of the world. With the increase in average life-expectancy, idiopathic Parkinson's disease (PD), is also expected to increase in prevalence. Furthermore, the high rate of consanguinity among Arabs probably makes familial cases of PD more likely to be encountered than other areas in the world. This review provides an update on the published literature on sporadic and familial PD in Gulf Arabs. SUMMARY: Although the Arab population of this region shares religious beliefs and demographic characteristics with other Arabs, their environmental exposures and genetic makeup may be different. This could account for the relatively low prevalence of PD reported in the Al-Thugba study (27 per 100,000) compared with prevalence rates by most other studies on Arab (mainly North African) populations (31.4-557.4 per 100,000). KEY MESSAGES: Gulf countries are considered rich countries, which makes conducting nation-wide or even international studies logistically easier than it is in many other countries. Such multinational research can be organized by the existing Gulf Cooperation Council, or through a collaboration of the Ministries of Health. This would, hopefully, culminate in the introduction of more research centers, as well as the implementation of better health care policies and practices for the ageing community.

Guillain-Barré syndrome in Arab countries: a systematic review.

Systematic review of the frequency and clinical pattern of Guillain-Barré syndrome (GBS) in Arab countries was initiated by a keyword search of PubMed, Medline and Embase and examination of references in all relevant papers. Seven articles were included from Iraq (n=1), Kuwait (n=1), Libya (n=2), and Saudi Arabia (n=3). The only incidence report from the Arab world, a 1987 study from Libya, gives an incidence of 1.7 per 100,000 person-years. Some studies reported that GBS was more common in males and in people in their twenties and thirties. Five studies showed that GBS occurred more frequently during the colder months, and antecedent infection was reported in 26-76% of cases. Most patients had an ascending pattern of weakness and almost all patients had lower limb weakness and reduced or absent reflexes. Facial weakness was the most common cranial nerve involvement. Only one study classified the GBS patients according to electrophysiological findings and reported that 68% of the patients had demyelination type and 15% axonal type. Protein level in cerebrospinal fluid is elevated in most of the GBS patients. Mortality rate from GBS was up to 8%. This systematic review shows an immense deficit in epidemiological data on GBS in Arab countries. The limited data show that clinical pattern, sex and age distribution, reported antecedent infection, and GBS subtypes are similar to those in Western countries. However, further well-designed epidemiological studies on GBS in the Arab world are needed.

Consultation on the Libyan health systems: towards patient-centred services.

The extra demand imposed upon the Libyan health services during and after the Libyan revolution in 2011 led the ailing health systems to collapse. To start the planning process to re-engineer the health sector, the Libyan Ministry of Health in collaboration with the World Health Organisation (WHO) and other international experts in the field sponsored the National Health Systems Conference in Tripoli, Libya, between the 26th and the 30th of August 2012. The aim of this conference was to study how health systems function at the international arena and to facilitate a consultative process between 500 Libyan health experts in order to identify the problems within the Libyan health system and propose potential solutions. The scientific programme adopted the WHO health care system framework and used its six system building blocks: i) Health Governance; ii) Health Care Finance; iii) Health Service Delivery; iv) Human Resources for Health; v) Pharmaceuticals and Health Technology; and vi) Health Information System. The experts used a structured approach starting with clarifying the concepts, evaluating the current status of that health system block in Libya, thereby identifying the strengths, weaknesses, and major deficiencies. This article summarises the 500 health expert recommendations that seized the opportunity to map a modern health systems to take the Libyan health sector into the 21st century.

Neurology expertise and postgraduate training programmes in the Arab world: a survey.

Neurological disorders are increasingly recognised as a major public health problem, especially in the developing world. Having adequate neurology expertise to tackle this issue is essential. A 17-item survey was conducted to gather information about the number, training and location of neurologists and supportive facilities available to them in the 16 middle- and high-income Arab countries. Data about the availability of postgraduate training programmes was collected. Surveys were returned from all targeted countries. The population per neurologist ranges from 35,000 to just over two million, and the most neurologists are based in large cities. Most of the practising neurologists had received extensive training in neurology and/or passed specialty exams. The majority had all or part of their training abroad. Neuro-radiological and neuro-physiological investigations are generally available in most surveyed countries but neuro-genetics and neuro-immunology services are lacking. Neurology training programmes are available in ten Arab countries with a total of 504-524 trainees. The availability of neurologists, supportive services and training programmes varies between Arab countries. Further development of neurology expertise and local training programmes are needed.
