Exploring the Relationship Between Sleep Quality, Sleep-Related Biomarkers, and Motor Skill Acquisition Using Virtual Reality in People With Parkinson's Disease: A Pilot Study

Background and Objectives: Despite the fact that sleep disturbances are among the most common and disabling manifestations of Parkinson's disease (PD), no study has investigated the effect of sleep quality and sleep-related biomarkers on motor skill acquisition in people with Parkinson's disease (PwPD).

Objective: To examine the relationship between skill acquisition, sleep quality, and sleep-related biomarkers in PwPD using virtual reality (VR) system.

Methods: This is a cross sectional study conducted on 31 PwPD and 31 healthy controls. To assess skill acquisition, each participant practiced a VR game 6 times (blocks). The main outcomes from the VR game were the required time to complete the VR game and the recorded errors. Motor skill acquisition was calculated as the difference of scores between block 6 and block 2 for both outcomes. Sleep was assessed subjectively using Pittsburgh Sleep Quality Index (PSQI) and objectively using the Actisleep. To assess sleep related biomarker, plasma serotonin level was examined.

Results: PwPD and healthy controls demonstrated a practice-related improvement in performance as shown by the main effect of block for each of the VR outcome measures (p < 0.000, time required to complete VR game; p < 0.000, recorded errors). There was no interaction effect between Block X Group for both outcome measures. There were significant correlations in both groups (p < 0.05) between motor skill acquisition (as indicated by the difference of time required to complete the VR game between block 6 and block 2) and PSQI total score, wake after sleep onset, and sleep efficiency. Additionally, a significant correlation was observed in both groups between motor skill acquisition (as indicated by the difference of time required to complete the VR game between block 6 and block 2) and the plasma serotonin level (p < 0.05). These correlations in PwPD remained significant, even after adjusting for disease motor severity, cognitive status, depression, and daily dose of L-dopa.

Discussion and Conclusions: Sleep quality may influence motor skill acquisition in PwPD. Healthcare professionals are encouraged to be aware about sleep quality and sleep assessment tools. Therapies may target improving sleep quality which could result in improving motor skill acquisition.

Implementation of sustainable complex interventions in health care services: the triple C model

BACKGROUND

The changing and evolving healthcare environment means organisations are under increasing pressure to deliver value-based, high quality care to patients through enabling access, reducing costs and improving outcomes. These factors result in an increased pressure to deliver efficient and beneficial interventions to improve patient care and support sustainability beyond the scope of the implementation of such interventions. Additionally, the literature highlights the importance of coordination, cooperation and working together across areas is critical to achieving implementation success. This paper discusses the development of a triple C model for implementation that supports sustainability of complex interventions in health care services.

METHODS

In order to develop the proposed implementation model, we adapted the formal tradition of theory building that is described in sociology. Firstly, we conducted a review of the literature on complex interventions and the available implementation models used to embed these interventions to identify the key aspects relating to successful implementation. Secondly, we devised a framework that encompassed these findings into a simple and workable model that can be easily embedded into everyday practice. This proposed model uses clear, systemic explanation, adds to the current knowledge in this area and is fit for purpose, providing healthcare workers with a simple easy-to-follow framework to embed practice change.

RESULTS

A three-stage implementation model was devised based on the findings of the literature and named the Triple C model (Consultation, Collaboration and Consolidation). The three stages are interconnected and overlap to support sustainability is considered at all levels of the project ensuring its greater success. This model considers the sustainability within any implementation project. Sustainability of interventions are a key consideration for continuous and successful change in any health care organisation. A set of criteria were developed for each of the three stages to support adaptability and sustainment of interventions are maintained throughout the life of the intervention.

CONCLUSION

Ensuring sustainability of interventions requires continuing effort and embedding the need for sustainability throughout all stages of an implementation project. The Triple C model offers a new approach for healthcare clinicians to support sustainability of organizational change.

The Migraine-Anxiety Comorbidity Among Migraineurs: A Systematic Review

Background: Migraine is recognized as a neurological condition that is often associated with comorbid psychiatric symptoms such as anxiety, depression, bipolar disorder and/or panic disorder. Though some studies have demonstrated the link between migraine and anxiety disorders, there are no systematic reviews that have been published in this area to summarize the evidence. The aim of the present study is to systematically review the literature associated with comorbidity of migraine and anxiety disorders among migraineurs compared to non-migraineurs.

Methods: The present systematic review included population-based, cohort and cross-sectional studies if they were reporting the frequency of migraine with either anxiety or depression as diagnosed by a medical practitioner according to the International Classification of Headache Disorders (ICHD-2/3).

Results: Eight eligible studies from 2060 relevant citations were included in the review. All participants were migraine patients from both primary care and outpatient settings, as well as tertiary headache and anxiety centers, and were compared to non-migraineurs. The results of the systematic review showed that there is a strong and consistent relationship between migraine and anxiety. The co-morbidity of co-occurrence for migraine and anxiety has an average OR of 2.33 (2.20–2.47) among the prevalence and cross sectional studies and an average RR of 1.63 (1.37–1.93) for two cohort studies; The major limitations of included studies were small sample sizes and a lack of adjusting of confounding factors.

Conclusion: The results highlight the need for inclusion of an anxiety screening tool during initial assessments of migraine patients by medical practitioners and/or physicians and may explain why some anxiolytic medications work better than others for migraine mitigation.

Measuring quality of life and identifying what is important to Jordanian living with multiple sclerosis using the Arabic version of the patient-generated index

BACKGROUND

Patient-generated index (PGI) is one of the individualized measures used to measure the quality of life (QOL) in people with different chronic conditions including multiple sclerosis (MS). However, the psychometric properties of the Arabic version of the PGI have not been fully established in Jordanian living with MS. Therefore, the objective of this study is to identify what matters to Jordanian living with MS and to contribute evidence toward the psychometric properties of the Arabic version of the PGI.

METHODS

A total of 75 participants with MS completed three QOL measures; PGI, the patient determined disease steps (PDDS), and EQ-5D. Generalized estimating equations were used to compare the total score of three QOL measures. Bland-Altman plot and Spearman's correlation coefficient were used to study the relationships and differences between the PGI and the other study measures (PDDS and EQ-5D).

RESULTS

Only 66 (88%) of the participants were able to complete the PGI. Overall, 36 areas of QOL concern were nominated by the participants using the PGI with the top three areas were emotional function (47%), involuntary movement reaction functions (45.5%), and walking (44 %). The average global score of the PGI was lower (34 ± 22) than the global score of the EQ-5D (69 ± 23), and the PDDS (68 ± 24). PGI had a moderate correlation with EQ-5D and PPDS.

CONCLUSION

The Arabic version of the PGI is a feasible, acceptable, and valid measure among Jordanians with MS. PGI also captures more important areas that contribute to QOL than EQ-5D and PDDS. PGI could improve the decision making and guide healthcare professionals to provide appropriate intervention programs to reduce the burdens from MS disease and improve QOL.

The clinical correlates of participation levels in people with multiple sclerosis

BACKGROUND

Multiple sclerosis (MS) has a huge impact on patients and affects their ability to participate in meaningful activities.

OBJECTIVE

To identify motor and non-motor factors that are associated with the participation level in instrumental activities of daily living (IADL), leisure, social and religious activities in people with MS.

METHOD

This is a cross-sectional study conducted on 110 individuals with MS. The used outcome measures are: Arabic version of the Activity Card Sort, Berg Balance Scale, Modified Fatigue Impact Scale, Nine Hole Peg Test, 6-Minute Walk Test, Brief International Cognitive Assessment for Multiple Sclerosis, Stroop test and Hospital Anxiety and Depression Scale.

RESULTS

Hand function, balance, gender and cognitive status can predict the participation in IADL (R2 = 0.425, P < 0.0001); depression, age, and cognitive status can predict the participation in leisure activities (R2 = 0.372, P < 0.0001), and fatigue, balance and cognitive status can predict social activities participation (R2 = 0.492, P < 0.000).

CONCLUSION

Balance, cognition and fatigue affect the level of participation in instrumental activities of daily living, leisure, and religious and social activities.

Serum vitamin d inversely correlates with depression scores in people with multiple sclerosis

BACKGROUND

Vitamin D (Vit.D) deficiency is a risk factor for multiple sclerosis (MS) and correlates with its severity. Depression is also common in people with MS (PWMS). We aim to investigate Vit.D correlation with depression risk scores in PWMS.

METHODS

A cross-sectional cohort of PWMS were studied. Clinical and demographic data were collected. The Hospital Anxiety Depression Scale (HADS) and the Beck Depression Inventory-II (BDI-II) were used to evaluate the risk of depression. Expanded Disability Status Scale (EDSS) and Patient Determined Disease Steps (PDDS) were used to evaluate the disability. Serum concentrations of 25-hydroxyvitamin D were measured. Bivariate and partial correlations of Vit.D status and scores of depressive and disability scales were statistically analyzed. The IBM Statistical Package for Social Sciences software, version 25.0, was used for data processing.

RESULTS

A total of 88 PWMS were enrolled. More than half of them had potential depression, and 68% had below-normal serum Vit.D levels (normal ≥ 30 ng/ml, insufficient = 21-29 ng/ml, and deficient ≤ 20 ng/ml). Serum Vit.D levels significantly correlated with scores of depression scales in both males and females, which was more robust in males. This association was maintained with a partial correlation analysis controlling for age, sex, body mass index, disease duration, type of MS, and EDDS HADS: r=-0.513, p<0.001; BDI-II: r=-0.401, p<0.001). Serum Vit.D had significant inverse correlations with EDSS score (r=-0.353, p = 0.001) and PDDS score (r=-0.341, p = 0.001), with more robust correlations in females compared to the whole group.

CONCLUSION

Vit.D levels correlate with depression risk scores in PWMS with differential sex effects.

Prevalence of Diarrheagenic Escherichia coli (DEC) and Salmonella spp. with zoonotic potential in urban rats in Salvador, Brazil

Studies evaluating the occurrence of enteropathogenic bacteria in urban rats (Rattus spp.) are scarce worldwide, specifically in the urban environments of tropical countries. This study aims to estimate the prevalence of diarrhoeagenic Escherichia coli (DEC) and Salmonella spp. with zoonotic potential in urban slum environments. We trapped rats between April and June 2018 in Salvador, Brazil. We collected rectal swabs from Rattus spp., and cultured for E. coli and Salmonella spp., and screened E. coli isolates by polymerase chain reaction to identify pathotypes. E. coli were found in 70% of Rattus norvegicus and were found in four Rattus rattus. DEC were isolated in 31.3% of the 67 brown rats (R. norvegicus). The pathotypes detected more frequently were shiga toxin E. coli in 11.9%, followed by atypical enteropathogenic E. coli in 10.4% and enteroinvasive E. coli in 4.5%. From the five black rats (R. rattus), two presented DEC. Salmonella enterica was found in only one (1.4%) of 67 R. norvegicus. Our findings indicate that both R. norvegicus and R. rattus are host of DEC and, at lower prevalence, S. enterica, highlighting the importance of rodents as potential sources of pathogenic agents for humans.

The Prevalence of Migraine With Anxiety Among Genders

Objective: The aims of the present systematic review were to explore the prevalence of migraine with anxiety exclusively and determine if and why there are likely to be differences across genders. Introduction: Migraine is a very common neurological disorder and cause of productive disability worldwide that is more frequent in women of childbearing age than males. Previous studies have frequently demonstrated comorbidity of migraine and other psychiatric disorders. Although the prevalence of migraine across gender is well-established there are few if any systematic reviews on the prevalence of migraine comorbidity with anxiety cross-genders. Methods: The present systematic review included prevalence studies, clinic-based and cohort studies that reported the frequency of migraine with anxiety within the study sample. Eleven studies were included in the review after screening by two independent reviewers. Studies included participants who were 16 years and older diagnosed with migraine. Results: The main findings of this review indicated that anxiety is a major comorbidity of migraine worldwide, with a wide range (16-83%) of prevalence and a mean of ~43% of patients experiencing comorbid symptoms. Subjective anxiety symptoms appear to be greater among males with migraine than females which could be attributable to both environmental and/or hormonal and genetic predispositions. Conclusions: The results reemphasize the high prevalence of migraine and comorbid anxiety symptoms worldwide while showing that although migraine is far more prevalent among women in general co-morbidity of migraine with anxiety unfolds a different gender difference. The results highlight the significance of exploring the impact of existing and pre-existing comorbid conditions of patients with migraines and further consideration into their diagnostic and treatment strategies.

The effect of stem cell therapy and comprehensive physical therapy in motor and non-motor symptoms in patients with multiple sclerosis: A comparative study

INTRODUCTION

People with multiple sclerosis (PwMS) experience a wide range of disabilities which negatively impact their quality of life (QOL). Several interventions have been used in PwMS such as medication, physical therapy exercises and stem cell therapy to improve their QOL. However, there is a limited evidence on the benefits of combining interventions. The purpose of this study is to explore the effect of combining physical therapy exercises (PTE) and Wharton Jelly mesenchymal stem cell (WJ-MSCs) injections on motor and non-motor symptoms versus each intervention alone in PwMS.

METHODS

Sixty PwMS will be allocated to either PTE, WJ-MSCs, or a combined group, followed up for 12 months and examined using a comprehensive battery of measures. Participants in the PTE group will receive 2 sessions per week of a supervised exercise program for 6 months followed by a home exercise program for another 6 months. The WJ-MSCs group will receive 3 WJ-MSCs injections in the first 6 months then they will be encouraged to follow an active life style. The third group will receive both interventions.

DISCUSSION

This study will aid in a better understanding of the combined effect of physical therapy and mesenchymal stem cell therapy. The results from this proposed study may reduce disability, improve QOL in PwMS, and consequently, reduce the cost associated with the life-time care of these individuals worldwide.

Medication safety challenges in Aboriginal Health Care services

OBJECTIVE

The aim of this study is to examine the challenges faced by the Aboriginal Health Practitioners in the community assisting their clients to manage medicines.

DESIGN

Qualitative, in depth interviews with eight Aboriginal Health Practitioners employed at various Aboriginal Community Controlled Health services in Victoria were undertaken.

SETTING

Rural Aboriginal Community Controlled Health Service.

PARTICIPANTS

Aboriginal Health Practitioners who are registered with the Aboriginal and Torres Strait Islander Health Practice Board of Australia as an Aboriginal Health Practitioner and who have experience in the planning, provision, management and evaluation of health services within their scope of practice.

RESULTS

This study revealed multiples challenges faced by Aboriginal Health Practitioners assisting clients with medication management. These were mainly divided into the attitudes and the culture of the workplace and barriers with medications use faced by the clients. The following subthemes were identified within the attitudes and workplace culture theme. These were reporting of errors, pamphlets not culturally appropriate, lack of education of Aboriginal Health Practitioner role and doctors' understanding of Aboriginal culture. The subthemes identified by the Aboriginal Health Practitioners that were specific to the clients included language barriers, immediacy, sharing medications by family members, medications disposal, self-diagnosis, traditional medicine, not feeling comfortable with doctors, literacy and alcohol use.

CONCLUSION

This study has identified many barriers to medication safety in the Aboriginal community, and strategies to improve some of the challenges identified.

Therapeutic Effects of Bilateral Anodal Transcranial Direct Current Stimulation on Prefrontal and Motor Cortical Areas in Children with Autism Spectrum Disorders: A Pilot Study

Dysfunctional frontal cortical areas associated with clinical features are observed in children with autism spectrum disorder (ASD). This study attempted to identify any potential therapeutic effects of bilateral anodal transcranial direct current stimulation (tDCS) applied over the left and right prefrontal and motor areas on the clinical characteristics of children with ASD. Fifty children with confirmed ASD medical diagnoses were divided equally and randomly into a tDCS treatment group and a control group. The tDCS treatment group underwent 10 sessions (20-min durations, five per week) of bilateral anodal tDCS stimulation applied simultaneously over the left and right prefrontal and motor areas, whereas the control group underwent the same procedures but with the use of sham tDCS stimulation. Total scores and sub-scores of autism treatment evaluation checklist (ATEC) (language and communication; sociability; sensory awareness; and behavioral, health, and physical conditions) were measured before and after the tDCS treatment sessions of both groups. There were significant decreases in total ATEC scores (P = 0.014), sociability sub-scores (P = 0.021), and behavioral, health, and physical condition sub-scores (P = 0.011) in the tDCS treatment group. No significant changes were observed in total ATEC scores and sub-scores in the control group. In conclusion, compared to the control group, bilateral anodal tDCS showed potential therapeutic effects on children with ASD in terms of improvements in sociability, behavior, health, and physical conditions with no reported side effects.

LAY SUMMARY: Dysfunctional frontal cortical areas are associated with clinical features in children with autism spectrum disorder (ASD). Transcranial direct current stimulation (tDCS) is found to be a safe, noninvasive method to stimulate cortical regions and thus have therapeutic effects on children with ASD. © 2020 International Society for Autism Research, Wiley Periodicals, Inc.

Pharmacological Treatment for Obesity in Adults: An Umbrella Review

Objective: To synthesize the evidence from systematic reviews of clinical trials investigating the effectiveness of pharmacological therapies approved by the Australian Therapeutic Goods Administration and the US Food and Drug Administration for the management of obesity in adults. Data Sources: A 3-step literature search of the MEDLINE, EMBASE, CINAHL, and PubMed databases was conducted between March and May 2019. The key terms used were obesity, pharmacological therapy, antiobesity agent, antiobesity medication, weight loss, and systematic review. Study Selection and Data Extraction: Systematic reviews that evaluated the effectiveness of pharmacological therapies for the management of obesity in patients with a body mass index of or greater than 25 kg/m². Data Synthesis: Nine systematic reviews involving three pharmacotherapies, liraglutide, orlistat, and naltrexone-bupropion were identified. The results indicate that the pharmacotherapies reduced weight when compared with placebo. Orlistat was effective in significantly reducing fasting blood glucose, HbA1c, total cholesterol, triglycerides, and systolic and diastolic blood pressure. All reviews discussed the presence or risk of gastrointestinal adverse effects including diarrhea, vomiting, and nausea related to orlistat and liraglutide. Relevance to Patient Care and Clinical Practice: This umbrella review compares the efficacy and safety of antiobesity medications for reducing weight and a discussion on their weight loss and metabolic control to guide clinicians when prescribing medications for obesity. Conclusions: All pharmacological therapies included in this review are superior to placebo in reducing weight. Clinicians should consider patient comorbidities and risk of adverse events when recommending medications for weight loss.

Adverse drug reactions in primary care: a scoping review

BACKGROUND

Medication-related adverse events, or adverse drug reactions (ADRs) are harmful events caused by medication. ADRs could have profound effects on the patients' quality of life, as well as creating an increased burden on the healthcare system. ADRs are one of the rising causes of morbidity and mortality internationally, and will continue to be a significant public health issue with the increased complexity in medication, to treat various diseases in an aging society. This scoping review aims to provide a detailed map of the most common adverse drug reactions experienced in primary healthcare setting, the drug classes that are most commonly associated with different levels/types of adverse drug reactions, causes of ADRs, their prevalence and consequences of experiencing ADRs.

METHODS

We systematically reviewed electronic databases Ovid MEDLINE, Embase, CINAHL Plus, Cochrane Central Register of Controlled Trials, PsycINFO and Scopus. In addition, the National Patient Safety Foundation Bibliography and the Agency for Health Care Research and Quality and Patient Safety Net Bibliography were searched. Studies published from 1990 onwards until December 7, 2018 were included as the incidence of reporting drug reactions were not prevalent before 1990. We only include studies published in English.

RESULTS

The final search yielded a total of 19 citations for inclusion published over a 15-year period that primarily focused on investigating the different types of adverse drug reactions in primary healthcare. The most causes of adverse events were related to drug related and allergies. Idiosyncratic adverse reactions were not very commonly reported. The most common adverse drug reactions reported in the studies included in this review were those that are associated with the central nervous system, gastrointestinal system and cardiovascular system. Several classes of medications were reported to be associated with adverse events.

CONCLUSION

This scoping review identified that the most causes of ADRs were drug related and due to allergies. Idiosyncratic adverse reactions were not very commonly reported in the literature. This is mainly because it is hard to predict and these reactions are not associated with drug doses or routes of administration. The most common ADRs reported in the studies included in this review were those that are associated with the central nervous system, gastrointestinal system and cardiovascular system. Several classes of medications were reported to be associated with ADRs.

Parkinson's Disease in the Middle East, North Africa, and South Asia: Consensus from the International Parkinson and Movement Disorder Society Task Force for the Middle East

BACKGROUND

Understanding the regional needs and available healthcare resources to treat Parkinson's disease (PD) is essential to plan appropriate future priorities. The International Parkinson and Movement Disorder Society (MDS) Task Force for the Middle East was established to raise awareness and promote education across the region on PD and other movement disorders. Broadly, the task force encompasses the countries of the Middle East but has included North Africa and South Asia as well (MENASA).

OBJECTIVE

To create a list of needs and priorities in the advancement of PD in MENASA countries based on consensuses generated by the MDS task force for the Middle East.

METHODS

A Strengths Weaknesses-Opportunities-Threats (SWOT) analysis was conducted by the task force members to generate consensus about PD care this region.

RESULTS

Eight overarching principles emerged for the consensus statement on current needs: more movement disorders specialists, multidisciplinary care, accurate epidemiologic data, educational programs, availability of drugs, and availability of more advanced therapy, enhanced health care resources and infrastructure, and greater levels of awareness within the general population and among health care professionals.

CONCLUSION

This pilot study sheds light on unmet needs for providing care to people with PD in the MENASA region. These data offer directions on priorities to increase awareness of PD, to develop better infrastructure for research and management of PD, to foster healthcare policy discussions for PD and to provide educational opportunities within these countries.

The effects of aerobic exercise on sleep quality measures and sleep-related biomarkers in individuals with Multiple Sclerosis: A pilot randomised controlled trial

BACKGROUND

Sleep disturbances are highly prevalent in people with multiple sclerosis(MS), and are associated with pain, fatigue, depression, and reduced quality of life (QoL). Importantly, sleep has been considered a critical brain state for motor learning and memory consolidation. Therefore, interventions that target sleep managementin people with MS are needed.

OBJECTIVES

To explore the effects of a six weeks moderate-intensity aerobic exercise intervention on sleep characteristics and sleep-related biomarkers specifically serotonin, melatoninand cortisol in people with MS using a pilot randomized controlled trial.

METHODS

Participants were randomly allocated to either a moderate-intensity aerobic exercise program (MAE, n = 20) or a home exercise program (HEP, n = 20). Participants were assessed at baseline and follow-up. Subjective and objective measures were used to assess sleep quality. The Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) were used to subjectively assess sleep. While Actigraphy was used to objectivelyassess sleep. Blood samples were collected for measurement of cortisol, melatonin and serotonin from MS participants in both groups at 8:00 am±1 hour.

RESULTS

Seventeen participants in the MAE and 13 in the HEP group completed the study. Compared to the HEP group, people with MS who participated in a moderate-intensity aerobic exercise experienced significant improvements (P < 0.05) on the PSQI, ISI, and several objective sleep parameters measured using actigraphy. Only the serotonin levels increased significantly over the six-week period in the MAE group compared to the HEP group. The change score in serotonin (from baseline to follow up assessment) was significantly correlatedwith the change score in PSQI (r = -0.97, p < 001) and the change score in ISI (r = -0. 56, p = 0.015) only in the MAE group but not the HEP group.

CONCLUSIONS

Exercise may be a non-pharmacological, inexpensive, safe method to improve sleep quality in people with MS. The improvement in the serotonin level due to aerobic exercisemight explain one of the physiologic mechanisms driving these improvements.
