RESUMO

OBJECTIVE: The contribution of somatic variants to epilepsy has recently been demonstrated, particularly in the etiology of malformations of cortical development. The aim of this study was to determine the diagnostic yield of somatic variants in genes that have been previously associated with a somatic or germline epilepsy model, ascertained from resected brain tissue from patients with multidrug-resistant focal epilepsy. METHODS: Forty-two patients were recruited across three categories: (1) malformations of cortical development, (2) mesial temporal lobe epilepsy with hippocampal sclerosis, and (3) nonlesional focal epilepsy. Participants were subdivided based on histopathology of the resected brain. Paired blood- and brain-derived DNA samples were sequenced using high-coverage targeted next generation sequencing to high depth (585× and 1360×, respectively). Variants were identified using Genome Analysis ToolKit (GATK4) MuTect-2 and confirmed using high-coverage Amplicon-EZ sequencing. RESULTS: Sequence data on 41 patients passed quality control. Four somatic variants were validated following amplicon sequencing: within CBL, ALG13, MTOR, and FLNA. The diagnostic yield across 41 patients was 10%, 9% in mesial temporal lobe epilepsy with hippocampal sclerosis and 20% in malformations of cortical development. SIGNIFICANCE: This study provides novel insights into the etiology of mesial temporal lobe epilepsy with hippocampal sclerosis, highlighting a potential pathogenic role of somatic variants in CBL and ALG13. We also report candidate diagnostic somatic variants in FLNA in focal cortical dysplasia, while providing further insight into the importance of MTOR and related genes in focal cortical dysplasia. This work demonstrates the potential molecular diagnostic value of variants in both germline and somatic epilepsy genes.

RESUMO

The mechanisms underlying the complications of mild traumatic brain injury, including post-concussion syndrome, post-impact catastrophic death, and delayed neurodegeneration remain poorly understood. This limited pathophysiological understanding has hindered the development of diagnostic and prognostic biomarkers and has prevented the advancement of treatments for the sequelae of mild traumatic brain injury. We aimed to characterize the early electrophysiological and neurovascular alterations following repetitive mild traumatic brain injury and sought to identify new targets for the diagnosis and treatment of individuals at risk of severe post-impact complications. We combined behavioural, electrophysiological, molecular, and neuroimaging techniques in a rodent model of repetitive mild traumatic brain injury. In humans, we used dynamic contrast-enhanced MRI to quantify blood-brain barrier dysfunction after exposure to sport-related concussive mild traumatic brain injury. Rats could clearly be classified based on their susceptibility to neurological complications, including life-threatening outcomes, following repetitive injury. Susceptible animals showed greater neurological complications and had higher levels of blood-brain barrier dysfunction, transforming growth factor ß (TGFß) signalling, and neuroinflammation compared to resilient animals. Cortical spreading depolarizations were the most common electrophysiological events immediately following mild traumatic brain injury and were associated with longer recovery from impact. Triggering cortical spreading depolarizations in mild traumatic brain injured rats (but not in controls) induced blood-brain barrier dysfunction. Treatment with a selective TGFß receptor inhibitor prevented blood-brain barrier opening and reduced injury complications. Consistent with the rodent model, blood-brain barrier dysfunction was found in a subset of human athletes following concussive mild traumatic brain injury. We provide evidence that cortical spreading depolarization, blood-brain barrier dysfunction, and pro-inflammatory TGFß signalling are associated with severe, potentially life-threatening outcomes following repetitive mild traumatic brain injury. Diagnostic-coupled targeting of TGFß signalling may be a novel strategy in treating mild traumatic brain injury.

RESUMO

Temporal lobe epilepsy, a common drug-resistant epilepsy in adults, is primarily a limbic network disorder associated with predominant unilateral hippocampal pathology. Structural MRI has provided an in vivo window into whole-brain grey matter structural alterations in temporal lobe epilepsy relative to controls, by either mapping (i) atypical inter-hemispheric asymmetry; or (ii) regional atrophy. However, similarities and differences of both atypical asymmetry and regional atrophy measures have not been systematically investigated. Here, we addressed this gap using the multisite ENIGMA-Epilepsy dataset comprising MRI brain morphological measures in 732 temporal lobe epilepsy patients and 1418 healthy controls. We compared spatial distributions of grey matter asymmetry and atrophy in temporal lobe epilepsy, contextualized their topographies relative to spatial gradients in cortical microstructure and functional connectivity calculated using 207 healthy controls obtained from Human Connectome Project and an independent dataset containing 23 temporal lobe epilepsy patients and 53 healthy controls and examined clinical associations using machine learning. We identified a marked divergence in the spatial distribution of atypical inter-hemispheric asymmetry and regional atrophy mapping. The former revealed a temporo-limbic disease signature while the latter showed diffuse and bilateral patterns. Our findings were robust across individual sites and patients. Cortical atrophy was significantly correlated with disease duration and age at seizure onset, while degrees of asymmetry did not show a significant relationship to these clinical variables. Our findings highlight that the mapping of atypical inter-hemispheric asymmetry and regional atrophy tap into two complementary aspects of temporal lobe epilepsy-related pathology, with the former revealing primary substrates in ipsilateral limbic circuits and the latter capturing bilateral disease effects. These findings refine our notion of the neuropathology of temporal lobe epilepsy and may inform future discovery and validation of complementary MRI biomarkers in temporal lobe epilepsy.

RESUMO

The purpose of our study was to explore how people with epilepsy fared during two of the most stringent 4-month society-wide COVID-19-related pandemic restrictions in Ireland, in 2020 and one year later in 2021. This was in the context of their seizure control, lifestyle factors, and access to epilepsy-related healthcare services. A 14-part questionnaire was administered to adults with epilepsy during virtual specialist epilepsy clinics in a University Hospital in Dublin, Ireland at the end of the two lockdowns. People with epilepsy were questioned on their epilepsy control, lifestyle factors, and quality of epilepsy-related medical care, compared to pre-COVID times. The study sample consisted of two separate cohorts of those diagnosed with epilepsy (100 (51.8%) in 2020, and 93 (48.2%) in 2021, with similar baseline characteristics. There was no significant change in seizure control or lifestyle factors from 2020 to 2021, except for deterioration in anti-seizure medication (ASM) adherence in 2021 compared to 2020 (p = 0.028). There was no correlation between ASM adherence and other lifestyle factors. Over the two years, poor seizure control was significantly associated with poor sleep (p < 0.001) and average seizure frequency in a month (p = 0.007). We concluded that there was no significant difference between seizure control or lifestyle factors between the two most stringent lockdowns in Ireland, in 2020 and 2021. Furthermore, people with epilepsy reported that throughout the lockdowns access to services was well maintained, and they felt well supported by their services. Contrary to the popular opinion that COVID lockdowns greatly affected patients with chronic diseases, we found that those with epilepsy attending our service remained largely stable, optimistic, and healthy during this time.

RESUMO

Traumatic brain injury (TBI) is a leading cause of morbidity and mortality worldwide. TBI ranges from mild to severe and is a recognized risk factor for later neurodegenerative conditions including chronic traumatic encephalopathy (CTE), Alzheimer disease (AD) and Parkinson disease (PD). The development of CTE is typically associated with repetitive exposure to mild TBI (mTBI), while a single moderate-to-severe TBI is considered a risk factor for AD and PD. Polypathology is common, and the lines between these conditions post TBI can be somewhat blurred. The mechanisms through which TBI leads to future neurodegeneration are not well understood. Heterogeneity and distance from the injury or injuries and individual genetic and environmental factors make clinical studies difficult. We present the case of an 82-year-old man who died 4 years after developing a phenotypically mixed dementia with neuropsychiatric features and parkinsonism. He had a remote history of a severe TBI 40 years prior, following a road traffic accident which caused a large right frontal injury, requiring neurosurgical intervention. Post-mortem neuropathological examination demonstrated abnormal phosphorylated-Tau (p-Tau), beta-amyloid plaques (Aß) and α-synuclein deposition. Spatial immunohistochemical analysis demonstrated increased perivascular accumulation of p-Tau with blood-brain barrier (BBB) disruption at the site of injury, which decreased with distance from the injury site. The appearances are suggestive of initial vascular disruption with persisting BBB disruption as a driver of the pathology.

RESUMO

AIMS: The causes of distinct patterns of reduced cortical thickness in the common human epilepsies, detectable on neuroimaging and with important clinical consequences, are unknown. We investigated the underlying mechanisms of cortical thinning using a systems-level analysis. METHODS: Imaging-based cortical structural maps from a large-scale epilepsy neuroimaging study were overlaid with highly spatially resolved human brain gene expression data from the Allen Human Brain Atlas. Cell-type deconvolution, differential expression analysis and cell-type enrichment analyses were used to identify differences in cell-type distribution. These differences were followed up in post-mortem brain tissue from humans with epilepsy using Iba1 immunolabelling. Furthermore, to investigate a causal effect in cortical thinning, cell-type-specific depletion was used in a murine model of acquired epilepsy. RESULTS: We identified elevated fractions of microglia and endothelial cells in regions of reduced cortical thickness. Differentially expressed genes showed enrichment for microglial markers and, in particular, activated microglial states. Analysis of post-mortem brain tissue from humans with epilepsy confirmed excess activated microglia. In the murine model, transient depletion of activated microglia during the early phase of the disease development prevented cortical thinning and neuronal cell loss in the temporal cortex. Although the development of chronic seizures was unaffected, the epileptic mice with early depletion of activated microglia did not develop deficits in a non-spatial memory test seen in epileptic mice not depleted of microglia. CONCLUSIONS: These convergent data strongly implicate activated microglia in cortical thinning, representing a new dimension for concern and disease modification in the epilepsies, potentially distinct from seizure control.

RESUMO

OBJECTIVE: Levetiracetam (LEV) is an effective antiseizure medicine, but 10%-20% of people treated with LEV report psychiatric side-effects, and up to 1% may have psychotic episodes. Pharmacogenomic predictors of these adverse drug reactions (ADRs) have yet to be identified. We sought to determine the contribution of both common and rare genetic variation to psychiatric and behavioral ADRs associated with LEV. METHODS: This case-control study compared cases of LEV-associated behavioral disorder (n = 149) or psychotic reaction (n = 37) to LEV-exposed people with no history of psychiatric ADRs (n = 920). All samples were of European ancestry. We performed genome-wide association study (GWAS) analysis comparing those with LEV ADRs to controls. We estimated the polygenic risk scores (PRS) for schizophrenia and compared cases with LEV-associated psychotic reaction to controls. Rare variant burden analysis was performed using exome sequence data of cases with psychotic reactions (n = 18) and controls (n = 122). RESULTS: Univariate GWAS found no significant associations with either LEV-associated behavioural disorder or LEV-psychotic reaction. PRS analysis showed that cases of LEV-associated psychotic reaction had an increased PRS for schizophrenia relative to contr ols (p = .0097, estimate = .4886). The rare-variant analysis found no evidence of an increased burden of rare genetic variants in people who had experienced LEV-associated psychotic reaction relative to controls. SIGNIFICANCE: The polygenic burden for schizophrenia is a risk factor for LEV-associated psychotic reaction. To assess the clinical utility of PRS as a predictor, it should be tested in an independent and ideally prospective cohort. Larger sample sizes are required for the identification of significant univariate common genetic signals or rare genetic signals associated with psychiatric LEV ADRs.

RESUMO

The epilepsies are commonly accompanied by widespread abnormalities in cerebral white matter. ENIGMA-Epilepsy is a large quantitative brain imaging consortium, aggregating data to investigate patterns of neuroimaging abnormalities in common epilepsy syndromes, including temporal lobe epilepsy, extratemporal epilepsy, and genetic generalized epilepsy. Our goal was to rank the most robust white matter microstructural differences across and within syndromes in a multicentre sample of adult epilepsy patients. Diffusion-weighted MRI data were analysed from 1069 healthy controls and 1249 patients: temporal lobe epilepsy with hippocampal sclerosis (n = 599), temporal lobe epilepsy with normal MRI (n = 275), genetic generalized epilepsy (n = 182) and non-lesional extratemporal epilepsy (n = 193). A harmonized protocol using tract-based spatial statistics was used to derive skeletonized maps of fractional anisotropy and mean diffusivity for each participant, and fibre tracts were segmented using a diffusion MRI atlas. Data were harmonized to correct for scanner-specific variations in diffusion measures using a batch-effect correction tool (ComBat). Analyses of covariance, adjusting for age and sex, examined differences between each epilepsy syndrome and controls for each white matter tract (Bonferroni corrected at P < 0.001). Across 'all epilepsies' lower fractional anisotropy was observed in most fibre tracts with small to medium effect sizes, especially in the corpus callosum, cingulum and external capsule. There were also less robust increases in mean diffusivity. Syndrome-specific fractional anisotropy and mean diffusivity differences were most pronounced in patients with hippocampal sclerosis in the ipsilateral parahippocampal cingulum and external capsule, with smaller effects across most other tracts. Individuals with temporal lobe epilepsy and normal MRI showed a similar pattern of greater ipsilateral than contralateral abnormalities, but less marked than those in patients with hippocampal sclerosis. Patients with generalized and extratemporal epilepsies had pronounced reductions in fractional anisotropy in the corpus callosum, corona radiata and external capsule, and increased mean diffusivity of the anterior corona radiata. Earlier age of seizure onset and longer disease duration were associated with a greater extent of diffusion abnormalities in patients with hippocampal sclerosis. We demonstrate microstructural abnormalities across major association, commissural, and projection fibres in a large multicentre study of epilepsy. Overall, patients with epilepsy showed white matter abnormalities in the corpus callosum, cingulum and external capsule, with differing severity across epilepsy syndromes. These data further define the spectrum of white matter abnormalities in common epilepsy syndromes, yielding more detailed insights into pathological substrates that may explain cognitive and psychiatric co-morbidities and be used to guide biomarker studies of treatment outcomes and/or genetic research.

RESUMO

As part of our ongoing interest in patient- and family-centered care in epilepsy, we began, before the onset of the CoVID-19 pandemic, to evaluate the concerns and preferences of those delivering and receiving care via telemedicine. CoVID-19 arrived and acted as an unexpected experiment in nature, catalyzing telemedicine's widespread implementation across many disciplines of medicine. The arrival of CoVID-19 in Ireland gave us the opportunity to record these perceptions pre- and post-CoVID. Data were extracted from the National Epilepsy Electronic Patient Record (EEPR). Power BI Analytics collated data from two epilepsy centers in Dublin. Analysis of data on reasons for using the telephone support line was conducted. A subset of patients and clinicians who attended virtual encounters over both periods were asked for their perception of telemedicine care through a mixed methods survey. Between 23rd December 2019 and 23rd March 2020 (pre-CoVID era), a total of 1180 patients were seen in 1653 clinical encounters. As part of a telemedicine pilot study, 50 of these encounters were scheduled virtual telephone appointments. Twenty eight surveys were completed by clinicians and 18 by patients during that period. From 24th March 2020 to 24th June 2020, 1164 patients were seen in 1693 encounters of which 729 (63%) patients were seen in 748 scheduled virtual encounters. 118 clinician impressions were captured through an online survey and 75 patients or carers completed a telephone survey during the post-CoVID era. There was no backlog of appointments or loss of care continuity forced by the pandemic. Clinicians expressed strong levels of satisfaction, but some doubted the suitability of new patients to the service or candidates for surgery receiving care via telemedicine. Patients reported positive experiences surrounding telephone appointments comparing them favorably to face-to-face encounters. The availability of a shared EEPR demonstrated no loss of care contact for patients with epilepsy. The survey showed that telemedicine is seen as an effective and satisfactory method of delivering chronic outpatient care.

RESUMO

OBJECTIVES: Electronic patient portals (ePortals) can facilitate greater healthcare democratization by providing patients and/or their authorized care partners with secure access to their medical records when and where needed. Such democratization can promote effective healthcare provider-patient partnerships, shared decision-making, and greater patient engagement in managing their health condition. This study examined the usefulness of providing individualized services and care in epilepsy (PiSCES), an epilepsy ePortal, as an enabler of more democratized epilepsy care. METHODS: Seventy-two individuals with epilepsy and 18 care partners were invited to report on their experience of interacting via PiSCES with clinical documents (epilepsy care summary record; epilepsy clinic letters) authored about them by healthcare providers. The OpenNotes reporting tool was adapted to capture participant experience. RESULTS: Twenty-five percent of invited patients and 44% of invited care partners reported on interacting with their epilepsy care summary; 14% of patients and 67% of care partners invited reported on their epilepsy clinic letters. Participant testimonials illustrate the value of PiSCES in: promoting autonomy, aiding memory, developing the knowledgeable patient, and enhancing healthcare partnerships. Ninety-six percent and 100% of respondents, respectively, reported understanding their epilepsy care summary and epilepsy clinic letter; 77% said the summary described their epilepsy history to date; 96% indicated that the letter provided an accurate description of their clinical encounter; 92% and 96%, respectively, valued access to their summary record and clinic letters; 77% of summary record and 73% clinic letter respondents reported learning something about their epilepsy or the healthcare service via PiSCES. Illustrating their potential patient and care partner safety role, 42% respondents identified inaccuracies in their clinical documents which were subsequently resolved by a clinician. SIGNIFICANCE: In the post-digital world highly customized on-demand products and services have come to be expected. Similarly, in epilepsy care, technologies such as PiSCES can enable more personalized, transparent, and engaging services.

RESUMO

BACKGROUND: This manuscript presents a framework to guide the identification and assessment of ethical opportunities and challenges associated with electronic patient records (EPR). The framework is intended to support designers, software engineers, health service managers, and end-users to realise a responsible, robust and reliable EPR-enabled healthcare system that delivers safe, quality assured, value conscious care. METHODS: Development of the EPR applied ethics framework was preceded by a scoping review which mapped the literature related to the ethics of EPR technology. The underlying assumption behind the framework presented in this manuscript is that ethical values can inform all stages of the EPR-lifecycle from design, through development, implementation, and practical application. RESULTS: The framework is divided into two parts: context and core functions. The first part 'context' entails clarifying: the purpose(s) within which the EPR exists or will exist; the interested parties and their relationships; and the regulatory, codes of professional conduct and organisational policy frame of reference. Understanding the context is required before addressing the second part of the framework which focuses on EPR 'core functions' of data collection, data access, and digitally-enabled healthcare. CONCLUSIONS: The primary objective of the EPR Applied Ethics Framework is to help identify and create value and benefits rather than to merely prevent risks. It should therefore be used to steer an EPR project to success rather than be seen as a set of inhibitory rules. The framework is adaptable to a wide range of EPR categories and can cater for new and evolving EPR-enabled healthcare priorities. It is therefore an iterative tool that should be revisited as new EPR-related state-of-affairs, capabilities or activities emerge.

RESUMO

Although 70% of people with epilepsy (PWE) achieve seizure freedom following an appropriate antiepileptic drug (AED) regime, evidence suggests that adherence to AEDs by PWE is suboptimal. Nonadherence to AEDs is associated with increased morbidity, mortality, emergency department visits, and hospitalizations, with reduced adherence also correlating to a lower quality of life, decreased productivity, and loss of employment. Furthermore, research indicates that medication errors which are widespread in chronic disease are less well studied in epilepsy but are likely also to contribute to avoidable disease morbidity and mortality. The goals of this project were to determine rates of medication adherence by self-reported questionnaire and its links to perceived medication error in a cohort of PWE attending a general epilepsy outpatient clinic. Following a plan-do-study-act cycle, it was found that the most appropriate methodology for conducting was in the form of a bespoke 9-item self-administered questionnaire. One hundred eighty-six PWE completed a nine-question questionnaire asking patients about their own medication adherence habits and their perception that they were previously exposed to medication error. This study found that 41% of respondents reported suboptimal adherence to AED therapy, while 28.5% of respondents self-reported that they unintentionally do not take their AED medication on an occasional, regular, or frequent basis. A 5.9% of respondents self-reported that they intentionally do not take their medication as prescribed. A 6% of respondents self-reported that they are both unintentionally and intentionally nonadherent to their AED therapy. No significant associations were demonstrated between age, sex, perceived effectiveness of medication, feelings of stigma/embarrassment, adverse effects or additional neurological comorbidities, and unintentional or intentional nonadherence. A 28.5% of respondents to the questionnaire reported that they perceived themselves to have been subjected to medication error. Prescribing errors were the most common form of perceived medication error, followed by dispensing errors, then administration errors. Significant associations were found between ineffective medication and feelings of stigma or embarrassment about epilepsy with perceived prescribing errors. Intentional nonadherence to medication was significantly associated with perceived dispensing errors.

RESUMO

The National Clinical Programme for Epilepsy (NCPE) in Ireland aims to deliver a holistic model of integrated person-centered care (PCC) that addresses the full spectrum of biomedical and psychosocial needs of people with epilepsy (PwE). However, like all strategic plans, the model encompasses an inherent set of assumptions about the readiness of the environment to implement and sustain the actions required to realize its goals. In this study, through the lens of PwE, the Irish epilepsy care setting was explored to understand its capacity to adopt a new paradigm of integrated PCC. Focus groups and semi-structured one-to-one interviews were employed to capture the qualitative experiences of a sample of Irish PwE (n = 27) in the context of the care that they receive. Participants were from different regions of the country and were aged between 18 and 55 years with 1 to 42 years since diagnosis (YSD). Highlighting a gap between policy intent and action on the ground, findings suggest that patient readiness to adopt a new model of care cannot be assumed. Expectations, preferences, behaviors, and values of PwE may sustain the more traditional constructions of healthcare delivery rather than the integrated PCC goals of reform. These culturally constituted perceptions illustrate that PwE do not instinctively appreciate the goals of healthcare reform nor the different behavior expected from them within a reformed healthcare system. Recalibrating deep-rooted patient views is necessary to accomplish the aspirations of integrated PCC. Patient engagement emphasizing the meaningful role that they can play in shaping their healthcare services is vital.

RESUMO

Telemedicine has been widely implemented during the COVID-19 global pandemic to enable continuity of care of chronic illnesses. We modified our general neurology clinic to be conducted using remote audio-only telephone consultations. We included all patients over a 10-week period who agreed to both a telephone consultation and a questionnaire afterwards in order to ascertain the patient's perspective of the experience. There were 212 participants consisting of men (43.8%) and women (56.2%). The mean ± standard deviation of age was 47.8 ± 17.0 (range 17-93) years. For the most part, patients found remote consultations either "just as good" (67.1%) or "better" (9.0%) than face-to-face consultations. Those who deemed it to be "not as good" were significantly older (52.3 ± 17.9 years vs. 46.6 ± 16.6 years, p =0.045) or were more likely to have a neurological disorder that required clinical examination, namely, a neuromuscular condition (66.7%, p = 0.002) or an undiagnosed condition (46.7%, p = 0.031). At the height of the COVID-19 global pandemic, most patients were satisfied with remote consultations. The positive feedback for remote consultations needs to be verified outside of this unique scenario because the results were likely influenced by the patients' apprehension to attend the hospital amongst other factors.

RESUMO

BACKGROUND: Electronic patient record (EPR) technology is a key enabler for improvements to healthcare service and management. To ensure these improvements and the means to achieve them are socially and ethically desirable, careful consideration of the ethical implications of EPRs is indicated. The purpose of this scoping review was to map the literature related to the ethics of EPR technology. The literature review was conducted to catalogue the prevalent ethical terms, to describe the associated ethical challenges and opportunities, and to identify the actors involved. By doing so, it aimed to support the future development of ethics guidance in the EPR domain. METHODS: To identify journal articles debating the ethics of EPRs, Scopus, Web of Science, and PubMed academic databases were queried and yielded 123 eligible articles. The following inclusion criteria were applied: articles need to be in the English language; present normative arguments and not solely empirical research; include an abstract for software analysis; and discuss EPR technology. RESULTS: The medical specialty, type of information captured and stored in EPRs, their use and functionality varied widely across the included articles. Ethical terms extracted were categorised into clusters 'privacy', 'autonomy', 'risk/benefit', 'human relationships', and 'responsibility'. The literature shows that EPR-related ethical concerns can have both positive and negative implications, and that a wide variety of actors with rights and/or responsibilities regarding the safe and ethical adoption of the technology are involved. CONCLUSIONS: While there is considerable consensus in the literature regarding EPR-related ethical principles, some of the associated challenges and opportunities remain underdiscussed. For example, much of the debate is presented in a manner more in keeping with a traditional model of healthcare and fails to take account of the multidimensional ensemble of factors at play in the EPR era and the consequent need to redefine/modify ethical norms to align with a digitally-enabled health service. Similarly, the academic discussion focuses predominantly on bioethical values. However, approaches from digital ethics may also be helpful to identify and deliberate about current and emerging EPR-related ethical concerns.

RESUMO

In line with healthcare reform across the world, the National Clinical Programme for Epilepsy (NCPE) in Ireland describes a model that aims to achieve holistic integrated person (patient)-centered care (PCC). While generally welcomed by stakeholders, the steps required to realize the NCPE ambition and the preparedness of those involved to make the journey are not clear. This study explored the perceptions of healthcare providers in the Irish epilepsy care ecosystem to understand their level of readiness to realize the benefits of an integrated PCC model. Ethnographic fieldwork including observations of different clinical settings across three regions in Ireland and one-to-one interviews with consultant epileptologists (n = 3), epilepsy specialist nurses (n = 5), general practitioners (n = 4), and senior healthcare managers (n = 3) were conducted. While there is a person-centered ambiance and a disposition toward advancing integrated PCC, there are limits to the readiness of the epilepsy care environment to fully meet the aspirations of healthcare reform. These are the following: underdeveloped healthcare partnerships;, poor care coordination;, unintended consequences of innovation;, and tension between pace and productivity. In the journey from policy to practice, the following multiple tensions collide: policy aims to improve services for all patients while simultaneously individualizing care; demands for productivity limit the time and space required to engage in incremental and iterative improvement initiatives. Understanding these tensions is an essential first step on the pathway to integrated PCC implementation.

RESUMO

A history of brain trauma has long been acknowledged as increasing an individual's risk of developing dementia in later life. The underlying mechanisms that belie this pre-disposition are, however, very poorly understood. Here, we report a clinical-neuropathological correlation of a man who presented at the age of 66 with a progressive complex atypical dementia with early and prominent neurobehavioral symptoms. His neurological condition continued to decline up to his death at the age of 74. During the compilation of his clinical history, it was established that the subject had experienced a single severe traumatic brain injury (TBI) aged 12 years in 1954 resulting in loss of consciousness, hospitalization, and coma for a number of days after which he was deemed to have recovered. Following post-mortem neuropathological analysis, numerous distinct neuropathologies were observed in various brain regions and these included i) widespread Braak stage VI neurofibrillary tangle formation, ii) widespread α-synuclein positive Lewy bodies and Lewy neurites and iii) diffuse amyloid plaques and severe cerebral amyloid angiopathy (CAA). Added to this, a comprehensive analysis of blood-brain barrier (BBB) integrity, known to be disrupted during and after TBI, showed iv) distinct BBB breakdown with extravasated IgG and activated microglia present. This report represents an interesting documented case of neuropolypathology that may be associated with prior history of severe TBI. We propose one testable theory that a history of brain trauma may be a potential trigger for late onset dementia due to damage and unresolved functioning of the cerebral microvasculature.

RESUMO

Robust prognostic indicators of neurological recovery are urgently needed for acutely comatose patients. Functional neuroimaging is a highly sensitive tool for uncovering covert cognition and awareness in behaviorally nonresponsive patients with prolonged disorders of consciousness, and may be applicable to acutely comatose patients. Establishing a link between early detection of covert awareness in acutely comatose patients and eventual recovery of function could have significant implications for patient prognosis, treatment, and end-of-life decisions. Because functional neuroimaging of acutely comatose patients is currently limited to the research context, ethical guidelines for disseminating a patient's individual research results to clinical teams and surrogate decision makers are needed. We propose an ethical framework composed of four conditions that can guide ethical disclosure of individual results of neuroimaging research in the acute care context.

RESUMO

Care for seizures in an emergency department setting can be variable, and there are disparities in access to onward specialist referral. The purpose of this study was to evaluate the utilization and implementation of an evidence-based seizure care pathway in a busy urban tertiary referral center. A total of 644 seizure presentations over two time points were examined. Initial pathway utilization rates were low at 26.2% but increased to 61.6% after environmental barriers had been addressed. We found that patients placed on the care pathway had higher rates of neurological examination, documentation of safety and legal guidelines as regards driving, and lower rates of seizure readmission. Twelve patients not placed on the pathway had passed away at follow-up (1.86%); the cause of death were related to significant comorbidities rather than the seizures themselves though in five, seizures could potentially have been a contributing factor. For the first time we have demonstrated that an evidence-based guideline for seizure management can be implemented in Ireland and used to standardize care for seizures in the emergency department improving documentation rates and clinical evaluation.

RESUMO

The aim of this study was to determine whether there were differences in experiences of care, satisfaction with care and quality of life between those who were in receipt of care from a service with an epilepsy specialist nurse (ESN) and those who were receiving care from a service that did not include an ESN. A comparative design was used, which involved the completion of a confidential, self-completed survey. The survey was administered to a nonprobability convenience sample of patients with epilepsy who were attending services with an ESN (n = 244) and services where the treatment team did not include an ESN (n = 261) from each of the four health areas in Ireland. This study found that, in comparison to people with epilepsy (PWE) who attended a service without an ESN, PWE who attended a service with an ESN reported receiving greater amount of information, were more involved in their care, perceived care to be better coordinated, and had greater confidence in the information provided and greater comfort in discussing issues with an ESN. They also reported higher rates of satisfaction with the emotional and practical support offered. Thus, it may be concluded that models of care involving the input of ESNs enhance the quality of epilepsy care and care processes. The findings also emphasize the need to have an ESN as part of the multidisciplinary team.
