RESUMEN

We aim to compare the outcomes in patients with atrial fibrillation detected after stroke (AFDAS) and their counterparts with known AF (KAF) presenting with large vessel occlusion (LVO) treated with mechanical thrombectomy (MT). This observational, prospective study included consecutive patients with acute LVO ischemic stroke of the anterior circulation with AFDAS, KAF and without AF. The primary study outcome was functional independence at 90 days after stroke. The secondary study outcomes were variation of the NIHSS score at 24 h, rate of successful reperfusion, death at 90 days and rate of immediate complications post-procedure. Overall, our cohort included 518 patients with acute ischemic stroke and LVO treated with MT, with 289 (56.8%) without a diagnosis of AF; 107 (21%) with AFDAS; 122 (22.2%) with KAF. There was no significant difference in terms of functional independence at 90 days after stroke between the three groups. Regarding the secondary study outcome, the rate of symptomatic intracranial haemorrhage (sICH) and/or parenchymal hematoma (PH) were significantly higher in the group of patients without AF (respectively, P = 0.030 and < 0.010). Logistic regression analysis showed that the subtypes of AF were not statistically significantly associated with functional independence at 90 days after stroke and with the likelihood of any ICH. Our results suggest that the subtypes of AF are not associated with clinical and safety outcomes of MT in patients with acute stroke and LVO. Further studies are needed to confirm our findings.

RESUMEN

During a bacterial infection, individuals may present with behavioral changes referred to as sickness behavior, which has been suggested is induced by the inflammatory markers that are released because of the infective immunological challenge. However, few studies have explored this multidimensional phenomenon in naturally occurring conditions. A longitudinal observational study was conducted to explore the role of inflammatory cytokines in mediating the sickness behavior during a bacterial infection. There were 13, 11 and 37 participants in the infection, hospital control and healthy groups, respectively. They were all followed up for 6 weeks and their inflammatory markers were quantified throughout those weeks. Cognitive function and depressive state were assessed by means of the Mini-Mental State Examination (MMSE) and Cornell Scale for Depression in Dementia (CSDD). Reductions in proinflammatory markers C-Reactive protein (CRP), interleukin - 6 (IL6) and tumor necrosis factor-α (TNFα) and increments in anti-inflammatory markers (interleukin - 4 (IL4)) were associated with an improvement in CSDD and MSEE in patients recovering from a bacterial infection. The correlation between inflammatory makers and CSDD was statistically significant for the CRP (r = 0.535, p = 0.001), the IL6 (r = 0.499, p < 0.001), the TNFα (r = 0.235, p = 0.007) and the IL4 (r = -0.321, p = 0.018). Inflammatory cytokines may mediate sickness behavior during acute illness. These results may enhance the understanding of the pathophysiology and potential treatment strategies to palliate this sickness behavior.

RESUMEN

Notwithstanding the oldest-old cohort being the fastest-growing population in most ageing societies, characterizing successful ageing in adults of advanced age, such as nonagenarians and centenarians, remains challenging. This study investigated the successful ageing subphenotypes using the data from Hong Kong Centenarian Study 2. Between April 2021 and September 2022, 146 family caregivers of community-dwelling older adults aged 95 or above were interviewed by phone. Latent class analysis identified three classes-Overall Frail (46.6%) with poor mobility, cognitive and functional health, Nonambulant (37.0%) but good functional health, and Robust (16.4%) with overall good health-from 11 indicators based on caregivers' reports. Although we found a low prevalence of fulfillment of all indicators of successful ageing, our findings will help care professionals appreciate the heterogeneity underlying partial successful ageing in this vulnerable cohort for segmented and targeted healthy longevity interventions.

RESUMEN

BACKGROUND: The evidence for mechanical thrombectomy in acute basilar artery occlusion has until now remained inconclusive with basilar artery strokes associated with high rates of death and disability. This systematic review and meta-analysis will summarize the available evidence for the effectiveness of mechanical thrombectomy in acute basilar artery occlusion compared to best medical therapy. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials using Embase, Medline and the Cochrane Central Register of Controlled Trials (CENTRAL). We calculated risk ratios (RRs) and 95% confidence intervals (CIs) to summarize the effect estimates for each outcome. RESULTS: We performed a random effects (Mantel-Haenszel) meta-analysis of the four included randomized controlled trials comprising a total of 988 participants. We found a statistically significant improvement in the rates of those with a good functional outcome (mRS 0-3, RR 1.54, 1.16-2.06, p = 0.003) and functional independence (mRS 0-2, RR 1.69, 1.05-2.71, p = 0.03) in those who were treated with thrombectomy when compared to best medical therapy alone. Thrombectomy was associated with a higher level of sICH (RR 7.12, 2.16-23.54, p = 0.001) but this was not reflected in a higher mortality rate, conversely the mortality rate was significantly lower in the intervention group (RR 0.76, 0.65-0.89, p = 0.0004). CONCLUSIONS: Our meta-analysis of the recently presented randomized controlled studies is the first to confirm the disability and mortality benefit of mechanical thrombectomy in basilar artery stroke.

RESUMEN

BACKGROUND: Seizures after stroke are an important clinical problem and may result in poor outcomes. The indications of antiepileptic drugs (AEDs) for seizure prophylaxis after stroke remain unclear. This is an updated version of the Cochrane Review previously published in 2014. OBJECTIVES: To assess the effects of AEDs for the primary and secondary prevention of seizures after stroke. For primary prevention, we aimed to assess whether AEDs reduce the likelihood of seizures in people who have a stroke but do not have a seizure. For secondary prevention, we aimed to assess whether AEDs reduce the likelihood of further seizures in people who have a stroke and at least one post-stroke seizure. SEARCH METHODS: We searched the following databases on 9 March 2021: Cochrane Register of Studies (CRS Web), MEDLINE (Ovid, 1946 to March 08, 2021). CRS Web includes randomised or quasi-randomised controlled trials from PubMed, Embase, ClinicalTrials.gov, the World Health Organisation International Clinical Trials Registry Platform (ICTRP), the Cochrane Central Register of Controlled Trials (CENTRAL), and the Specialised Registers of Cochrane Review Groups including Epilepsy and Stroke. We also checked the reference lists of articles retrieved from these searches. SELECTION CRITERIA: We selected randomised and quasi-randomised controlled studies that recruited participants with a clinical diagnosis of stroke, either ischaemic or haemorrhagic. We excluded studies that only recruited participants with subarachnoid haemorrhage, subdural haemorrhage, extradural haemorrhage, or other non-stroke diagnoses such as tumour- or infection-related infarction or haemorrhage. We also excluded studies that recruited only participants who had undergone neurosurgery. We included participants of all ages suffering any seizure type who were assigned to AEDs or placebo groups. DATA COLLECTION AND ANALYSIS: In accordance with standard methodological procedures expected by The Cochrane Collaboration, two review authors independently assessed trials for inclusion before evaluating trial risk of bias and extracting relevant data. The primary outcome assessed was the proportion of participants who experienced seizures in the follow-up period. We presented results as summary risk ratios (RRs) with 95% confidence intervals (CIs) for dichotomous outcomes and mean differences (MDs) with 95% CIs for continuous outcomes. Where we had sufficient data, we calculated random-effects (Mantel-Haenszel) meta-analyses for dichotomous outcomes; otherwise, we reported results narratively. We used the I2 statistic to analyse statistical heterogeneity. We planned to use funnel plots to assess publication bias in meta-analyses with at least 10 included studies. We used the GRADE approach to assess the certainty of the evidence. MAIN RESULTS: Two studies with a total of 856 subjects were included. AEDs were not shown to be effective in primary prophylaxis of post-stroke seizure (RR 0.65, 95% CI 0.34 to 1.26; 2 studies, 856 participants; moderate-certainty evidence). The first study was a randomised double-blind study comparing valproic acid with placebo for primary seizure prevention up to one year after stroke. The study included 72 adults with intracerebral haemorrhage. There was no difference in the risk of post-stroke seizures (RR 0.88, 95% CI 0.35 to 2.16) or of death (RR 1.20, 95% CI 0.40 to 3.58). The second study was a substudy on the use of diazepam in acute stroke. It was a randomised double-blind study, comparing a three-day diazepam treatment versus placebo for primary seizure prevention up to three months after stroke in 784 adults with acute stroke. There was no evidence of a difference in the risk of post-stroke seizures for all stroke or subgroups of haemorrhagic or ischaemic stroke (RR for all stroke 0.47, 95% CI 0.18 to 1.22). In a subgroup analysis of anterior circulation cortical infarcts, primary prophylaxis with diazepam was associated with a reduced risk of post-stroke seizures (RR 0.21, 95% CI 0.05 to 0.95). Risks of mortality did not differ between the diazepam and the placebo group at two weeks (RR 0.84, 95% CI 0.56 to 1.26) and three months follow-up (RR 0.95, 95% CI 0.72 to 1.26). We assessed both studies to be at a low overall risk of bias. Using the GRADE approach, we assessed the overall certainty of the evidence as low to moderate. AUTHORS' CONCLUSIONS: There is insufficient evidence to support the routine use of AEDs on the primary and secondary prevention of seizures after stroke. Further well-conducted studies are warranted for this important clinical problem.

RESUMEN

BACKGROUND: Cerebral small vessel disease is a progressive disease of the brain's deep perforating blood vessels. It is usually diagnosed based on lesions seen on brain imaging. Cerebral small vessel disease is a common cause of stroke but can also cause a progressive cognitive decline. As antithrombotic therapy is an established treatment for stroke prevention, we sought to determine whether antithrombotic therapy might also be effective in preventing cognitive decline in people with small vessel disease. OBJECTIVES: To assess the effects of antithrombotic therapy for prevention of cognitive decline in people with small vessel disease on neuroimaging but without dementia. SEARCH METHODS: We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Review Group's Specialised Register, and the Cochrane Stroke Group's Specialised Register; the most recent search was on 21 July 2021. We also searched MEDLINE, Embase, four other databases and two trials registries. We searched the reference lists of the articles retrieved from these searches. As trials with a stroke focus may include relevant subgroup data, we complemented these searches with a focussed search of all antithrombotic titles in the Cochrane Stroke Group database.  SELECTION CRITERIA: We included randomised controlled trials (RCT) of people with neuroimaging evidence of at least mild cerebral small vessel disease (defined here as white matter hyperintensities, lacunes of presumed vascular origin and subcortical infarcts) but with no evidence of dementia. The trials had to compare antithrombotic therapy of minimum 24 weeks' duration to no antithrombotic therapy (either placebo or treatment as usual), or compare different antithrombotic treatment regimens. Antithrombotic therapy could include antiplatelet agents (as monotherapy or combination therapy), anticoagulants or a combination. DATA COLLECTION AND ANALYSIS: Two review authors independently screened all the titles identified by the searches. We assessed full texts for eligibility for inclusion according to our prespecified selection criteria, extracted data to a proforma and assessed risk of bias using the Cochrane tool for RCTs. We evaluated the certainty of evidence using GRADE. Due to heterogeneity across included participants, interventions and outcomes of eligible trials, it was not possible to perform meta-analyses. MAIN RESULTS: We included three RCTs (3384 participants). One study investigated the effect of antithrombotic therapy in participants not yet on antithrombotic therapy; two studies investigated the effect of additional antithrombotic therapy, one in a population already taking a single antithrombotic agent and one in a mixed population (participants on an antithrombotic drug and antithrombotic-naive participants). Intervention and follow-up durations varied from 24 weeks to four years. Jia 2016 was a placebo-controlled trial assessing 24 weeks of treatment with DL-3-n-butylphthalide (a compound with multimodal actions, including a putative antiplatelet effect) in 280 Chinese participants with vascular cognitive impairment caused by subcortical ischaemic small vessel disease, but without dementia. There was very low-certainty evidence for a small difference in cognitive test scores favouring treatment with DL-3-n-butylphthalide, as measured by the 12-item Alzheimer's Disease Assessment Scale-Cognitive subscale (adjusted mean difference -1.07, 95% confidence interval (CI) -2.02 to -0.12), but this difference may not be clinically relevant. There was also very low-certainty evidence for greater proportional improvement measured with the Clinician Interview-Based Impression of Change-Plus Caregiver Input (57% with DL-3-n-butylphthalide versus 42% with placebo; P = 0.01), but there was no difference in other measures of cognition (Mini-Mental State Examination and Clinical Dementia Rating) or function. There was no evidence of a difference in adverse events between treatment groups. The SILENCE RCT compared antithrombotic therapy (aspirin) and placebo during four years of treatment in 83 participants with 'silent brain infarcts' who were on no prior antithrombotic therapy. There was very low-certainty evidence for no difference between groups across various measures of cognition and function, rates of stroke or adverse events. The Secondary Prevention of Subcortical Stroke Study (SPS3) compared dual antiplatelet therapy (clopidogrel plus aspirin) to aspirin alone in 3020 participants with recent lacunar stroke. There was low-certainty evidence of no effect on cognitive outcomes as measured by the Cognitive Abilities Screening Instruments (CASI) assessed annually over five years. There was also low-certainty evidence of no difference in the annual incidence of mild cognitive decline between the two treatment groups (9.7% with dual antiplatelet therapy versus 9.9% with aspirin), or the annual stroke recurrence rate (2.5% with dual antiplatelet therapy versus 2.7% with aspirin). Bleeding risk may be higher with dual antiplatelet therapy (hazard ratio (HR) 2.15, 95% CI 1.49 to 3.11; low certainty evidence), but there may be no significant increase in intracerebral bleeding risk (HR 1.52, 95% CI 0.79 to 2.93; low-certainty evidence). None of the included trials assessed the incidence of new dementia. AUTHORS' CONCLUSIONS: We found no convincing evidence to suggest any clinically relevant cognitive benefit of using antithrombotic therapy in addition to standard treatment in people with cerebral small vessel disease but without dementia, but there may be an increased bleeding risk with this approach. There was marked heterogeneity across the trials and the certainty of the evidence was generally poor.

RESUMEN

BACKGROUND: Atrial fibrillation (AF) is associated with an increased risk of dementia. Little is known about the relationship of antithrombotic therapy and the risk of dementia in patients with AF without clinical stroke. METHOD: This was an observational study based on a hospital AF registry. Patients aged 65-85 years at the time of AF diagnosis were identified via the computerised database of the clinical management system. Patients with prior stroke or known cognitive dysfunction were excluded. The primary outcome was newly diagnosed dementia during the follow-up period. RESULTS: 3284 patients (mean age 76.4±5.3 years, 51.6% male) were included for analysis. The mean CHA2DS2-VASc score was 3.94±1.44. 18.5% patients were prescribed warfarin, 39.8% were prescribed aspirin and 41.7% were prescribed no antithrombotic therapy. After a mean follow-up of 3.6 years, 71 patients (2.2%) developed dementia, giving rise to an incidence of 0.61%/year. The incidence of dementia were 1.04%/year, 0.69%/year and 0.14%/year for patients on no therapy, aspirin and warfarin, respectively. Both univariate and multivariate analyses showed that age ≥75 years, female gender and high CHA2DS2-VASc score were associated with significantly higher risk of dementia; warfarin use was associated with significantly lower risk of dementia (HR: 0.14%, 95% CI 0.05 to 0.36, p<0.001). Patients on warfarin with time in therapeutic range (TTR) ≥65% had a non-significant trend towards a lower risk of dementia compared with those with TTR <65%. CONCLUSION: In elderly AF patients, warfarin therapy was associated with a significantly lower risk of new-onset dementia compared those with no therapy or aspirin.

RESUMEN

BACKGROUND AND PURPOSE: The global COVID-19 pandemic led many stroke centres worldwide to shift from in-person to telemedicine consultations to assess patients with transient ischaemic attacks (TIAs). We aimed to investigate the impact of telemedicine during the COVID-19 pandemic on the management and outcome of the patients with TIA. METHODS: We retrospectively analysed data from a registry of consecutive TIA patients assessed at the Stroke Department, Imperial College Health Care Trust, London, during the national lockdown period (between March 23 2020 and 30 June 2020). As controls, we evaluated the clinical reports and stroke quality metrics of patients presenting to the TIA clinic in the same period of 2019. RESULTS: Between 23 March 2020 and 30 June 2020, 136 patients were assessed using the telemedicine TIA clinic, compared to 180 patients evaluated with face-to-face consultation in the same period in 2019. Patients' characteristics were similar in both groups. At 3 months after the TIA, there were no significant differences in the proportion of patients admitted to the hospital for recurrent TIA/stroke or any other cardiovascular cause from the 2020 period compared to the same period in 2019. CONCLUSIONS: Our analysis showed that during the pandemic, our telemedicine consultations of TIA patients were not associated with an increased 3-month rate of recurrent TIA/stroke or cardiovascular hospital admissions. More robust studies looking at this model of care will be needed to assess its long-term effects on patients and health care systems.

RESUMEN

INTRODUCTION: We examined the impact of the coronavirus disease 2019 (COVID-19) pandemic on our regional stroke thrombectomy service in the UK. METHODS: This was a single-center health service evaluation. We began testing for COVID-19 on 3 March and introduced a modified "COVID Stroke Thrombectomy Pathway" on 18 March. We analyzed the clinical, procedural and outcome data for 61 consecutive stroke thrombectomy patients between 1 January and 30 April. We compared the data for January and February ("pre-COVID," n = 33) versus March and April ("during COVID," n = 28). RESULTS: Patient demographics were similar between the 2 groups (mean age 71 ± 12.8 years, 39% female). During the COVID-19 pandemic, (a) total stroke admissions fell by 17% but the thrombectomy rate was maintained at 20% of ischemic strokes; (b) successful recanalization rate was maintained at 81%; (c) early neurological outcomes (neurological improvement following thrombectomy and inpatient mortality) were not significantly different; (d) use of general anesthesia fell significantly from 85 to 32% as intended; and (e) time intervals from onset to arrival, groin puncture, and recanalization were not significantly different, whereas internal delays for external referrals significantly improved for door-to-groin puncture (48 [interquartile range (IQR) 39-57] vs. 33 [IQR 27-44] minutes, p = 0.013) and door-to-recanalization (82.5 [IQR 61-110] vs. 60 [IQR 55-70] minutes, p = 0.018). CONCLUSION: The COVID-19 pandemic has had a negative impact on the stroke admission numbers but not stroke thrombectomy rate, successful recanalization rate, or early neurological outcome. Internal delays actually improved during the COVID-19 pandemic. Further studies should examine the effects of the COVID-19 pandemic on longer term outcome.

RESUMEN

OBJECTIVES: Mild cognitive impairment (MCI) refers to an early but abnormal state of cognitive impairment with minimal functional impairment. The present study aimed to evaluate the validity of Fuld Object Memory Evaluation (FOME) as a measure of episodic memory function. METHOD: The study sample included 204 Chinese older adults with cognitive impairments. The participants completed five recall trials and a delayed trial in FOME, neurocognitive measures on digit spans and trail making, and daily functioning. Discriminative power of FOME to differentiate between MCI and dementia was inspected via receiver operating characteristic curve analysis. RESULTS: FOME showed good test-retest reliability and convergent validity with digit spans and trail making. Controlling for gender, age, and education, lower levels of FOME total retrieval, verbal fluency, and daily functioning significantly predicted a higher likelihood of dementia compared to MCI. The optimal cut-off scores for total retrieval, verbal fluency, and daily functioning to differentiate dementia were 37/38 (77% sensitivity and 83% specificity), 28/29 (85% sensitivity and 72% specificity), and 14/15 (92% sensitivity and 78% specificity), respectively, in the younger subgroup. The corresponding figures were 34/35 (69% sensitivity and 76% specificity) and 27/28 (92% sensitivity and 62% specificity), and 11/12 (74% sensitivity and 80% specificity), respectively, in the older subgroup. CONCLUSION: The findings support the FOME as a valid assessment tool of episodic memory function in older Chinese adults. The combined use of FOME and daily functioning is recommended to distinguish persons with dementia from MCI.

RESUMEN

AIM: To examine the effect of a video-supported nurse-led advance care planning to frail geriatric patients on end-of-life decision-making outcomes in patients and their carers. DESIGN: This is a double-blinded randomized controlled trial with parallel arms. METHODS: The protocol was approved by the Institutional Review Board of the participating hospital on 1 August 2018. Frail elders and their carer if any are enrolled during hospitalization, and undergo randomization after discharged. The intervention group receives a 2-week video-supported nurse-led advance care planning programme (N = 149) while the control group receives a 2-week health education program at home (N = 149). Follow-up surveys via telephone at 1 and 6 months measure outcomes regarding end-of-life decision-making from both the patients and the carers. CONCLUSION: Advance care planning discussion is to understand patient's values, preferences and treatment for care on their anticipation of future deterioration. Treatment options for end-of-life care may not be well-received especially elders because in the discussion process, technical medical terms are presented in an abstract, hypothetical way that are hard to understand. The present study aims to evaluate the effect of a nurse-led advance care planning supplementing with a video showing end-of-life treatment options to promote end-of-life care decision-making among frail geriatric patients. IMPACT: The results will help identify effective elements of advance care planning and inform the development of an evidence?based structured advance care planning intervention in response to the need for quality end-of-life care. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR-IOR-17012341.

RESUMEN

BACKGROUND: The Montreal Cognitive Assessment (MoCA) is psychometrically superior over the Mini-mental State Examination (MMSE) for cognitive screening in stroke or transient ischemic attack (TIA). It is free for clinical and research use. The objective of this study is to convert scores from the MMSE to MoCA and MoCA-5-minute protocol (MoCA-5 min) and to examine the ability of the converted scores in detecting cognitive impairment after stroke or TIA. METHODS: A total of 904 patients were randomly divided into training (n = 623) and validation (n = 281) samples matched for demography and cognition. MMSE scores were converted to MoCA and MoCA-5 min using (1) equipercentile method with log-linear smoothing and (2) Poisson regression adjusting for age and education. Receiver operating characteristics curve analysis was used to examine the ability of the converted scores in differentiating patients with cognitive impairment. RESULTS: The mean education was 5.8 (SD = 4.6; ranged 0-20) years. The entire spectrum of MMSE scores was converted to MoCA and MoCA-5 min using equipercentile method. Relationship between MMSE and MoCA scores was confounded by age and education, and a conversion equation with adjustment for age and education was derived. In the validation sample, the converted scores differentiated cognitively impaired patients with area under receiver operating characteristics curve 0.826 to 0.859. CONCLUSION: We provided 2 methods to convert scores from the MMSE to MoCA and MoCA-5 min based on a large sample of patients with stroke or TIA having a wide range of education and cognitive levels. The converted scores differentiated patients with cognitive impairment after stroke or TIA with high accuracy.

RESUMEN

OBJECTIVE: Very old adults may be physically frail, but they do not necessarily experience poor subjective health. The authors hypothesized that the relationship between frailty and subjective health is moderated by depression for very old people. METHODS: In a cross-sectional study, a survey administered was by a face-to-face interview to 129 community-dwelling older adults aged 95-108. Measurements included the five-item FRAIL scale, the Geriatric Depression Scale Short-Form (GDS), and a subjective health rating. Hierarchical multiple regressions were conducted to test the moderation effects, adjusting for age, gender, living arrangement, perceived socioeconomic status, and cognition. RESULTS: The interaction effect between frailty and depression was significant. Inspection of the simple slopes revealed that those who were more depressed had a more negative frailty-subjective health relationship. There was no significant moderation effect for a withdrawal-apathy-vigor dimension of the GDS. CONCLUSION: Our findings suggest a protective psychological mechanism may enable very old adults to maintain an optimistic view of their health despite their increasing physical and functional limitations.

RESUMEN

BACKGROUND: Intracranial venous thrombosis (ICVT) commonly presents with seizures in the acute period, and some people may develop recurrent seizures in the long term. The prophylactic use of antiepileptic drugs (AEDs) for the management of post-ICVT seizures is controversial, and there is currently no consensus on the optimal management of post-ICVT seizures. This is an updated version of the Cochrane review first published in theCochrane Database of Systematic Reviews 2006, Issue 3. OBJECTIVES: To assess the effects of AEDs for the primary and secondary prevention of seizures related to ICVT.(1) For the question of primary prevention, we aimed to examine whether AEDs reduce the likelihood of seizures in people who have had an ICVT but have not had a seizure.(2) For the question of secondary prevention, we aimed to examine whether AEDs reduce the likelihood of further seizures in people who have had an ICVT and at least one seizure. SEARCH METHODS: For the latest update, we searched the Cochrane Epilepsy Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online (CRSO), and MEDLINE (Ovid 1946 onwards) to 20 April 2015, and we checked the reference lists of articles retrieved from the searches. SELECTION CRITERIA: We planned to include all randomised and quasi-randomised controlled trials in which participants with a diagnosis of ICVT were assigned to a treatment group (that is, receiving at least one AED) or control group (receiving placebo or no drug). DATA COLLECTION AND ANALYSIS: Both review authors independently screened and assessed the methodological quality of the studies. If studies had been included in the review, one review author would have extracted the data and another would have checked the extracted data. MAIN RESULTS: No relevant studies were found. AUTHORS' CONCLUSIONS: There is no evidence to support or refute the use of antiepileptic drugs for the primary or secondary prevention of seizures related to intracranial venous thrombosis. Well-designed randomised controlled trials are urgently needed to inform practice. Since the last version of this review no new studies have been found.

RESUMEN

OBJECTIVES: To evaluate rehabilitation outcomes in patients with moderate to severe cognitive impairment. DESIGN: Prospective observational cohort study. SETTING: Rehabilitation unit for older people. SUBJECTS: A total of 116 patients (70F) mean age (SD) 86.3 (6.4). Group 1: 89 patients with moderate cognitive impairment (Mini-Mental State Examination 11-20); and Group 2: 27 patients with severe cognitive impairment (Mini-Mental State Examination 0-10). INTERVENTION: A personalised rehabilitation plan. MAIN MEASURES: Barthel Activity of Daily Living score on admission and discharge, length of stay and discharge destination. RESULTS: Of 116 patients, 64 (55.2%) showed an improvement in Barthel score. Mini-Mental State Examination was significantly higher in those who improved, 15.4 (SD 3.7) vs.13.2 (SD 5.1): p = 0.01. The mean Barthel score improved in both groups; Group 1 - 14.7 (SD 19.1) vs. Group 2 - 9.3 (SD 16.3): p = 0.17. Of 84 home admissions in Group 1, more patients returning home showed improvements of at least 5 points in the Barthel score compared with nursing/residential home discharges (32/37 - 86.5% vs. 10/28 - 35.7%: p = 0.0001). In Group 2 of 17 home admissions, 6/6 (100%) home discharges showed improvement compared with 3/7 (42.8%) discharges to nursing/residential home (p = 0.07). In Group 1, a discharge home was associated with significantly greater improvement in number of Barthel items than a nursing/residential home discharge (3.27 (SD 2.07) vs. 1.86 (SD 2.32): p = 0.007). A similar non-significant pattern was noted for severe cognitive impairment patients (3.5 (3.06) vs. 1.14 (1.06); p = 0.1). CONCLUSION: Patients with moderate to severe cognitive impairment demonstrated significant improvements in Barthel score and Barthel items showing that such patients can and do improve with rehabilitation.

RESUMEN

BACKGROUND: This is an updated version of the original Cochrane review published in 2010, Issue 1. Seizures after stroke are an important clinical problem, and they may be associated with poor outcome. The effects of antiepileptic drugs for the primary and secondary prevention of seizures after stroke remain unclear. OBJECTIVES: We aimed to assess the effects of antiepileptic drugs for the primary and secondary prevention of seizures after stroke. SEARCH METHODS: We searched the Specialised Registers of the Cochrane Epilepsy Group (12 August 2013) and the Cochrane Stroke Group (12 August 2013), the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2013, Issue 7), and MEDLINE (OVID, 1946 to 12 August 2013). We also checked the reference lists of articles retrieved from these searches. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials in which participants were assigned to treatment or control group (placebo or no drug). DATA COLLECTION AND ANALYSIS: Two review authors independently screened all the titles, abstracts, and keywords of publications identified by the searches to assess their eligibility, and both review authors assessed their suitability for inclusion according to prespecified selection criteria. We included only one study for data collection and analysis. MAIN RESULTS: We found only one trial that fulfilled the study inclusion criteria of comparison of the effects of an antiepileptic drug with placebo (or no drug) for the primary or secondary prevention of seizures after stroke. This was a prospective randomised, double-blind, placebo-controlled trial comparing valproic acid with placebo for primary prevention of seizures in 72 adults (over 18 years of age) with spontaneous non-aneurysmal, non-traumatic intracerebral haemorrhage; no statistically significant difference in outcome (seizure occurrence at one year) was demonstrated between groups. AUTHORS' CONCLUSIONS: Currently, there is insufficient evidence to support the routine use of antiepileptic drugs for the primary or secondary prevention of seizures after stroke. Further well-conducted research is needed for this important clinical problem.
