Project description:Little is known about the contribution of aphasia to the cost of care for patients who experience stroke.We retrospectively examined a cohort of South Carolina Medicare beneficiaries who experienced ischemic stroke in 2004 to determine the attributable cost of aphasia. Univariate analyses were used to compare demographic, comorbidity, and severity differences between individuals with poststroke aphasia and those without aphasia. Differences in payments by Medicare because of stroke were examined using a gamma-distributed generalized linear multivariate model.Three thousand, two hundred Medicare beneficiaries experienced ischemic stroke in South Carolina in 2004, and 398 beneficiaries had poststroke aphasia. Patients with aphasia experienced longer length of stays, greater morbidity, and greater mortality than did those without aphasia. In adjusted models that controlled for relevant covariates, the attributable 1-year cost of aphasia was estimated at $1703.Aphasia adds to the cost of stroke-related care, above the cost of stroke alone.

Project description:This article reviews the treatment of functional neurological symptoms during World War I by Lewis Yealland at the National Hospital for the Paralysed and Epileptic in London. Yealland was among the first doctors in Britain to incorporate electricity in the systematic treatment of shell shock. Our analysis is based on the original case records of his treatment of 196 soldiers with functional motor and sensory symptoms, functional seizures and somatoform disorders. Yealland's treatment approach integrated peripheral and central electrical stimulation with a variety of other--psychological and physical--interventions. A combination of electrical stimulation of affected muscles with suggestion of imminent improvement was the hallmark of his approach. Although his reported success rates were high, Yealland conducted no formal follow-up. Many of the principles of his treatment, including the emphasis on suggestion, demonstration of preserved function and the communication of a physiological illness model, are encountered in current therapeutic approaches to functional motor and sensory symptoms. Yealland has been attacked for his use of electrical stimulation and harsh disciplinary procedures in popular and scientific literature during and after World War I. This criticism reflects changing views on patient autonomy and the social role of doctors and directly impacts on current debates on ethical justification of suggestive therapies. We argue that knowledge of the historical approaches to diagnosis and management of functional neurological syndromes can inform both aetiological models and treatment concepts for these challenging conditions.

Project description:Poststroke aphasia (PSA) results from direct effect of focal lesions and dysfunction of distributed language networks. However, how flexible the activity at specific nodes control global dynamics is currently unknown. In this study, we demonstrate that alterations in the regional activity may cause imbalances between segregation and integration in temporo-spatial pattern, and the transient dynamics are disrupted in PSA patients. Specifically, we applied dynamic framework to eyes-closed resting-state functional MRI data from PSA patients (n =?17), and age-, gender-, and education-matched healthy controls (HCs, n =?20). Subsequently, we calculated two basis brain organizational principles: "dynamic segregation," obtained from dynamic amplitude of low-frequency fluctuations (dALFF), which represent the specialized processing within interconnected brain regions; and "dynamic integration," obtained from dynamic functional connectivity, which measures the efficient communication between interconnected brain regions. We found that both measures were decreased in the PSA patients within the left frontal and temporal subregions compared to the HCs. PSA patients displayed increased flexibility of interaction between left temporo-frontal subregions and right temporo-parieto-frontal subnetworks. Furthermore, we found that dALFF in the pars triangularis of left inferior frontal gyrus was associated with aphasia quotient. These findings suggest that the reduced temporal flexibility of regional activity in language-relevant cortical regions in PSA is related to the disrupted organization of intrahemispheric networks, leading to a loss of the corresponding functions. By using dynamic framework, our results offer valuable information about the alterations in segregation and integration of spatiotemporal information across networks and illuminate how dysfunction in flexible activity may underlie language deficits in PSA.

Project description:OBJECTIVE:To determine if pretreatment nonlinguistic cognition predicted language treatment outcomes and if so, which specific nonlinguistic cognitive subskills predicted naming therapy outcomes. DESIGN:Retrospective. SETTING:Research clinic. PARTICIPANTS:Study 1 included data from 67 persons with aphasia who underwent language treatment and a pretreatment cognitive-linguistic assessment battery (N=67). Study 2 included data from 27 study 1 participants who completed additional pretreatment nonlinguistic cognitive assessments. INTERVENTIONS:120-minute sessions of sentence comprehension (n=26) or naming treatment (n=41) 2 times per week for up to 10-12 weeks. MAIN OUTCOME MEASURES:Proportion of potential maximal gain (PMG) (assessed immediately after treatment [10-12wk]; formula=mean posttreatment score-mean pretreatment score/total number of trained items-mean pretreatment score) and proportion of potential maximal gain maintained (PMGM) (assessed 12wk after posttreatment [22-24wk]; formula=mean maintenance score-mean pretreatment score/total number of trained items-mean pretreatment score) as outcome variables; and pretreatment assessment scores as predictor variables. RESULTS:In study 1, 37% of participants demonstrated nonlinguistic cognitive deficits. Principal component analyses reduced assessment data to 2 components: linguistic and nonlinguistic cognition. Backward elimination regression revealed that higher linguistic and nonlinguistic cognitive function significantly predicted higher PMG after language therapy. In study 2, principal component analysis of only the nonlinguistic cognitive measures identified 3 components: executive function, verbal short-term memory, and visual short-term memory. Controlling for pretreatment apraxia of speech and auditory comprehension deficits, regression analyses revealed that higher executive function and visual short-term memory significantly predicted higher PMG and PMGM after naming therapy. CONCLUSIONS:Pretreatment nonlinguistic cognitive function significantly influenced language treatment outcomes and maintenance of therapy gains.

Project description:The effects of noninvasive neurostimulation on brain structure and function in chronic poststroke aphasia are poorly understood. We investigated the effects of intermittent theta burst stimulation (iTBS) applied to residual language-responsive cortex in chronic patients using functional and anatomical MRI data acquired before and after iTBS. Lateralization index (LI) analyses, along with comparisons of inferior frontal gyrus (IFG) activation and connectivity during covert verb generation, were used to assess changes in cortical language function. Voxel-based morphometry (VBM) was used to assess effects on regional grey matter (GM). LI analyses revealed a leftward shift in IFG activity after treatment. While left IFG activation increased, right IFG activation decreased. Changes in right to left IFG connectivity during covert verb generation also decreased after iTBS. Behavioral correlations revealed a negative relationship between changes in right IFG activation and improvements in fluency. While anatomical analyses did not reveal statistically significant changes in grey matter volume, the fMRI results provide evidence for changes in right and left IFG function after iTBS. The negative relationship between post-iTBS changes in right IFG activity during covert verb generation and improvements in fluency suggests that iTBS applied to residual left-hemispheric language areas may reduce contralateral responses related to language production and facilitate recruitment of residual language areas after stroke.

Project description:BackgroundWhite matter hyperintensities (WMH) are a radiological marker of brain health that has been associated with language status in poststroke aphasia; however, its association with language treatment outcomes remains unknown.ObjectiveTo determine whether WMH in the right hemisphere (RH) predict response to language therapy independently from demographics and stroke lesion-related factors in poststroke aphasia.MethodsWe used the Fazekas scale to rate WMH in the RH in 30 patients with poststroke aphasia who received language treatment. We developed ordinal regression models to examine language treatment effects as a function of WMH severity after controlling for aphasia severity, stroke lesion volume, time post onset, age, and education level. We also evaluated associations between WMH severity and both pre-treatment naming ability and executive function.ResultsThe severity of WMH in the RH predicted treatment response independently from demographic and stroke-related factors such that patients with less severe WMH exhibited better treatment outcome. WMH scores were not significantly correlated with pretreatment language scores, but they were significantly correlated with pretreatment scores of executive function.ConclusionWe suggest that the severity of WMH in the RH is a clinically relevant predictor of treatment response in this population.

Project description:Background and purposeThe factors associated with recovery of language domains after stroke remain uncertain. We described recovery of overall-language-ability, auditory comprehension, naming, and functional-communication across participants' age, sex, and aphasia chronicity in a large, multilingual, international aphasia dataset.MethodsIndividual participant data meta-analysis of systematically sourced aphasia datasets described overall-language ability using the Western Aphasia Battery Aphasia-Quotient; auditory comprehension by Aachen Aphasia Test (AAT) Token Test; naming by Boston Naming Test and functional-communication by AAT Spontaneous-Speech Communication subscale. Multivariable analyses regressed absolute score-changes from baseline across language domains onto covariates identified a priori in randomized controlled trials and all study types. Change-from-baseline scores were presented as estimates of means and 95% CIs. Heterogeneity was described using relative variance. Risk of bias was considered at dataset and meta-analysis level.ResultsAssessments at baseline (median=43.6 weeks poststroke; interquartile range [4-165.1]) and first-follow-up (median=10 weeks from baseline; interquartile range [3-26]) were available for n=943 on overall-language ability, n=1056 on auditory comprehension, n=791 on naming and n=974 on functional-communication. Younger age (<55 years, +15.4 Western Aphasia Battery Aphasia-Quotient points [CI, 10.0-20.9], +6.1 correct on AAT Token Test [CI, 3.2-8.9]; +9.3 Boston Naming Test points [CI, 4.7-13.9]; +0.8 AAT Spontaneous-Speech Communication subscale points [CI, 0.5-1.0]) and enrollment <1 month post-onset (+19.1 Western Aphasia Battery Aphasia-Quotient points [CI, 13.9-24.4]; +5.3 correct on AAT Token Test [CI, 1.7-8.8]; +11.1 Boston Naming Test points [CI, 5.7-16.5]; and +1.1 AAT Spontaneous-Speech Communication subscale point [CI, 0.7-1.4]) conferred the greatest absolute change-from-baseline across each language domain. Improvements in language scores from baseline diminished with increasing age and aphasia chronicity. Data exhibited no significant statistical heterogeneity. Risk-of-bias was low to moderate-low.ConclusionsEarlier intervention for poststroke aphasia was crucial to maximize language recovery across a range of language domains, although recovery continued to be observed to a lesser extent beyond 6 months poststroke.

Project description:BackgroundIn 2015, the drive-through pharmacy was first introduced in Queen Elizabeth Hospital (QEH), Malaysia as one of the pharmacy value-added services. Therefore, it is imperative to review the service for further amelioration to fulfil patients' needs and expectations.ObjectiveThe aim of this study is to evaluate the drive-through pharmacy service in Queen Elizabeth Hospital, Malaysia.MethodsA cross-sectional observational study was conducted from July to December 2018. The questionnaire was developed and underwent thorough validation process which yielded a Cronbach's alpha reliability score of 0.9130. Satisfaction was calculated by mean percentage score (0% (dissatisfied) to 100% (satisfied). All data were analysed descriptively and thematic analysis was used in analysing open-ended question.ResultsCompliance in obtaining medication was at 96.3% with a given two-week grace collection period. Insufficient quantity of medications (33.3%) was the highest near-missed medication errors occurred at the drive-through pharmacy. The mean satisfaction percentage score for all patients were 76.6%?±?8.1. A total of 69.2% (n?=?83) were "very satisfied" while 30.8% (n?=?37) were "satisfied" with the service. Among the reasons for satisfaction are convenience in getting medication refills (n?=?74, 62%), short waiting time (n?=?75, 63%) and knowledgeable dispensers (n?=?87, 73%). A handful of patients were "dissatisfied" with the opening hours (n?=?14, 11.7%) and the location of the drive-through pharmacy service (n?=?19, 15.8%).ConclusionCompliance in medication collection is acceptable within stipulated grace period. Despite low occurrence, identification of near-missed medication errors provides useful insights for future improvement of the service. Generally, our patients are satisfied with the service. However, we need to re-evaluate on the opening hours and location of the service.

Project description:Background: All children, whether healthy or ill, should have access to equal educational opportunities. Healthcare institutions and hospitals have been approved to work with schools to establish learning centers to provide education to sick children. This study has been conducted to develop a practical model for learning centers in hospitals across Thailand to create equality and ensure valuable human resources for the future. The main goal of this study was to evaluate the effectiveness of a hospital learning center for continuing education of child patients and to determine the factors that are most appropriate study plans, the parents' attitude about their child's illness, and the children's satisfaction with the learning center. Methods: The total sample population was 400, consisting of 200 parents and 200 child patients aged 4 to 18 years. The respondents were given a questionnaire to obtain their feedback using a Likert scale. Results: The most common child patients were those with chronic illness followed by those with common illnesses, and lastly children with developmental problems. All 200 children received continuing education; 20 child patients (10%) who had been evaluated received a modified education plan. After analyzing the results of satisfaction with the learning center, the scores ranged from 4.21 to 5.00 (mean = 4.28, SD = 0.62). Conclusions: Sick children can continue their education at the hospital learning center in Queen Sirikit National Institute of Child Health. Study plans can be modified to suit children with chronic illnesses and developmental problems, children in primary and secondary school, and those requiring prolonged hospitalization. Parents in the study had appropriate attitudes about the disease and education of their children. Sick children gave the highest ratings showing extremely high satisfaction with the hospital learning center.

Project description:The study of language network plasticity following left hemisphere stroke is foundational to the understanding of aphasia recovery and neural plasticity in general. Damage in different language nodes may influence whether local plasticity is possible and whether right hemisphere recruitment is beneficial. However, the relationships of both lesion size and location to patterns of remapping are poorly understood. In the context of a picture naming fMRI task, we tested whether lesion size and location relate to activity in surviving left hemisphere language nodes, as well as homotopic activity in the right hemisphere during covert name retrieval and overt name production. We found that lesion size was positively associated with greater right hemisphere activity during both phases of naming, a pattern that has frequently been suggested but has not previously been clearly demonstrated. During overt naming, lesions in the inferior frontal gyrus led to deactivation of contralateral frontal areas, while lesions in motor cortex led to increased right motor cortex activity. Furthermore, increased right motor activity related to better naming performance only when left motor cortex was lesioned, suggesting compensatory takeover of speech or language function by the homotopic node. These findings demonstrate that reorganization of language function, and the degree to which reorganization facilitates aphasia recovery, is dependent on the size and site of the lesion.
