The predictive value of early response in patients with depressive disorders

Objective: Several randomized controlled trials have identified early response to psychotherapy as a predictor for later treatment outcome among patients with depressive disorders. However, supporting evidence under routine conditions is rare. This study evaluated the predictive value of early improvement for final outcomes in psychotherapy among depressive patients in the naturalistic setting of a German university outpatient clinic. Method: We used the method of percent symptom reduction to classify 639 patients with major depression or dysthymic disorder who underwent an average of 40.0 sessions (SD?=?16.3) of naturalistic cognitive–behavioral therapy (CBT) as having either an early response or an early nonresponse. Results: Early response was a good predictor for final response and remission regarding depressive symptoms (OR?=?8.75 and OR?=?5.32, respectively), as well as overall psychological distress (OR?=?3.95 and OR?=?3.16, respectively). Early nonresponse was distinctly associated with later deterioration of both depressive (OR?=?9.56) and general psychological symptomatology (OR?=?4.92). Conclusions: Early response to psychotherapy has high predictive qualities for positive later treatment outcome in depressive patients under routine CBT. Therefore, early treatment effects should be considered in clinical decision-making and treatment planning in everyday clinical practice.     

Subarachnoid hemorrhage rebleeding in the first 24 h is associated with external ventricular drain placement and higher grade on presentation: Cohort study

BackgroundRebleeding after aneurysmal subarachnoid hemorrhage (aSAH) confers a poor prognosis; however, risk factors and differential outcomes associated with early rebleeding in the first 24 h after symptom presentation are incompletely understood.MethodsA retrospective cohort study of all aSAH presenting to our institution between 2001 and 2016 was performed. Early rebleeding events were defined as clinical neurologic decline with radiographically confirmed acute intracranial hemorrhage within 24 h after symptom presentation. Univariate and multivariate logistic regression analyses were used to assess clinical associations, with a specific focus on baseline Glasgow Coma Score (GCS), World Federation of Neurosurgical Societies (WFNS), and modified Fisher scores.ResultsOf 471 aSAH cases, 33 (7%) experienced early rebleeding. Multivariate regression identified extraventricular drain (EVD) placement (OR = 2.16, P = 0.04) and WFNS 3–5 (OR = 2.69, P = 0.02) as significant predictors of early rebleeding. Good functional outcomes were observed in 8 patients with early rebleeding (24%), all of whom underwent aneurysm treatment. Higher SAH grade prior to rebleeding (WFNS 3–5) was significantly associated with increased odds of an unfavorable functional outcome (OR = 8.09, P < 0.01). Anticoagulation, aneurysm size and location were not significantly associated with either early rebleeding incidence or functional outcome.ConclusionsEarly rebleeding in aSAH is associated with unfavorable functional outcomes. EVD placement and higher SAH grade on presentation appear to be significantly and independently associated with increased risk of rebleeding within first 24 h, as well as unfavorable long-term functional outcome; however, the clinical benefit of hyper-acute aneurysm treatment requires further investigation.     

The concurrent and predictive validity of symptomatic remission criteria in first-episode schizophrenia

BackgroundSince the introduction of consensus criteria for symptomatic remission in 2005, most first-episode studies focused on cross-sectional relationship between remission status and functional outcome. Predictive validity of the proposed remission definition was under-studied. Relationship of remission with subjective quality of life (QoL) was inadequately addressed with inconsistent findings being observed.MethodOne hundred and four Hong Kong Chinese aged 18 to 55 years presenting with first-episode schizophrenia-spectrum disorder were studied. Socio-demographics, baseline clinical and functioning profiles were obtained. Psychopathological and functional reassessments were conducted at 6, 12 and 24 months. Subjective QoL was measured at 12 and 24 months. Symptomatic remission was operationally defined according to the consensus criteria developed by the Remission in Schizophrenia Working Group (RSWG), comprising both symptom-severity and 6-month duration components.ResultsAt 12 months, 59.6% of patients achieved symptomatic remission. Remitted patients had significantly lower symptom severity, more favorable psychosocial functioning and better subjective QoL at 12 months than non-remitted counterparts. Attainment of remission at 12 months was significantly associated with fewer positive, negative, depressive and disorganization symptoms, higher levels of functioning and subjective QoL at 24 months. Linear regression analysis indicated that remission status independently predicted functional outcome even when the effects of educational level, baseline functioning and negative symptom scores were controlled for.ConclusionThe operationally defined symptomatic remission formulated by the RSWG represented a clinically valid construct that was found to be closely related to both concurrent and longitudinal outcomes on psychopathology, functioning and subjective QoL in the early stage of schizophrenia.     

Impact of medications,mood state,and electrode placement on ECT outcomes in treatment-refractory psychosis

BackgroundTreatment-refractory psychosis (TRP) is a significant clinical challenge. While clozapine is frequently effective, alternate or augmentation strategies are often necessary. Evidence supports effectiveness of electroconvulsive therapy (ECT), but questions remain about optimal treatment parameters and impacts of concomitant pharmacotherapy.Objective/Hypothesis: To analyze the impact of clozapine, anticonvulsant medication, mood state, and ECT electrode placement on outcomes in TRP. We hypothesized that ECT would lead to greater reduction in positive symptoms, particularly in patients receiving clozapine.MethodsRetrospective study in a tertiary TRP program. The Positive and Negative Syndrome Scale (PANSS) was used for clinical outcomes, with positive subscore as primary outcome. Clinical and ECT data were analyzed using a linear modelling approach, controlling for relevant covariates.ResultsA total of 309 patients were included. ECT plus clozapine associated with greater improvement in positive, general, and total symptoms than ECT alone. ECT associated with greater improvement in negative symptoms in depressed patients. Bifrontal placement was mostly equivalent to bitemporal, with greater reduction of positive symptoms in patients receiving clozapine, and associated with lower electrical dose in patients on anticonvulsants. Clozapine increased seizure duration, while anticonvulsants decreased it. Anticonvulsant use in ECT patients associated with equivalent to slightly improved symptom reduction.ConclusionsECT's benefit in TRP may be greatest in patients receiving clozapine. ECT can improve negative symptoms in depressed TRP patients. Bifrontal placement is effective in TRP. Clozapine and anticonvulsants have opposite effects on seizure duration, but anticonvulsants may not adversely affect clinical outcomes of ECT for TRP.     

Cauda equina syndrome due to disk herniation: Long-term functional prognosis

ObjectiveCauda equina syndrome (CES) caused by lumbar disk extrusion is classically considered an indication of urgent surgery. CES can be subdivided into CESI (incomplete CES) and CESR (complete CES with urinary retention and incontinence). This paper evaluates the long-term functional outcome of a CES cohort operated on due to disk herniation.MethodsSingle-center retrospective observational study. CES patients due to disk herniation that underwent surgery between 2000 and 2016 were included in the study. Demographic data, time intervals to diagnosis and surgery, preoperative neurologic status and outcome at the end of follow up were recorded.ResultsTwenty-two patients were included (median age 44 years). Eight patients were CESR and 14 CESI. Median time from symptom onset to diagnosis was 78 h (range, 12–720 h), and from diagnosis to surgery 24 h (range, 5–120 h). Median follow up was 75 months (range, 20–195 months). At the end of follow up, in the CESR group (median time from diagnosis to surgery, 23 h) only pain significantly improved after surgery (p = 0.007). In the CESI group (median time from diagnosis to surgery 23 h) low back pain, sciatica and urinary sphincter function significantly improved (p < 0.001). There were no significant differences between early (<48 h) operation (n = 4) and late (n = 18) in terms of sphincter recovery (Fisher's Exact Test, p = 0.076).ConclusionPain associated to CES improved both in the CESI and CESR groups. However, urinary sphincter impairment significantly improved only in the CESI group. No significant differences were found regarding long-term functional outcome between early and late surgery.     

Patient characteristics and the therapist as predictors of depressed patients’ outcome expectation over time: A multilevel analysis

Objective: Although there is an established link between patients’ early positive outcome expectation for and their actual improvement from therapy, there is little research on patients’ change in outcome expectation across therapy and both patient and therapist correlates of early outcome expectation level and change. The present study examined: (i) the overall trajectory of change in patients’ outcome expectation through cognitive-behavioral therapy (CBT) for depression; (ii) patient characteristics as predictors of both initial outcome expectation and change in outcome expectation; and (iii) between-therapist effects in outcome expectation change. Method: Depressed patients (N?=?143) received a brief course of CBT. Outcome expectation was measured at screening, pretreatment, session 7, and session 14. Results: Outcome expectation linearly increased from screening to session 14. When controlling for other patient characteristics at intake, having previous depressive episodes was negatively associated with initial outcome expectation and higher well-being was positively associated with initial outcome expectation. When controlling for early alliance and early symptom change, outcome expectation change was predicted by previous depressive episodes. Finally, therapist effects emerged in outcome expectation over time. Conclusions: Various depressed patients’ characteristics predict initial outcome expectation level and change, with significant between-therapists’ differences related to outcome expectation change.     

Early Trauma Is Associated with Poor Pharmacological Treatment Response in Patients with Panic Disorder

Objective Pharmacotherapy is established as an effective method for reducing symptoms of panic disorder (PD). However, about 20–40% of PD patients are treatment-resistant. Predictors of pharmacotherapy outcomes for PD patients are needed. Methods This study included 152 PD patients to measure the clinical severities of PD symptoms and used the Early Trauma Inventory (ETI) to measure early trauma. Treatment response was defined as a 40% reduction in the total Panic Disorder Severity Scale score from baseline. We measured the treatment responses at 8 weeks and 6 months. Binary logistic regression was used to predict treatment response after controlling for confounding variables. Results Early sexual trauma alone was associated with poor treatment response at 8 weeks. However, at 6 months, the total ETI score was associated with an unfavorable treatment response. Conclusion Therefore, our study suggests that clinicians need to be aware of a history of early trauma to optimize treatment outcomes for PD patients.     

Meta-analysis of brain structural changes after electroconvulsive therapy in depression

BackgroundIncreases in the volume of the amygdala and hippocampus after electroconvulsive therapy (ECT) are among the most robust effects known to the brain-imaging field. Recent advances in the segmentation of substructures of these regions allow for novel insights on the relationship between brain structure and clinical outcomes of ECT.ObjectiveWe aimed to provide a comprehensive synthesis of evidence available on changes in brain structure after ECT, including recently published data on hippocampal subfields.MethodsA meta-analysis of published studies was carried out using random-effects models of standardized mean change of regional brain volumes measured with longitudinal magnetic resonance imaging of depressive patients before and after a series of ECT.ResultsData from 21 studies (543 depressed patients) were analysed, including 6 studies (118 patients) on hippocampal subfields. Meta-analyses could be carried out for seven brain regions for which data from at least three published studies was available. We observed increases in left and right hippocampi, amygdalae, cornua ammonis (CA) 1, CA 2/3, dentate gyri (DG) and subicula with standardized mean change scores ranging between 0.34 and 1.15. The model did not reveal significant volume increases in the caudate. Meta-regression indicated a negative relationship between the reported increases in the DG and relative symptom improvement (−0.27 (SE: 0.09) per 10%).ConclusionsECT is accompanied by significant volume increases in the bilateral hippocampus and amygdala that are not associated with treatment outcome. Among hippocampal subfields, the most robust volume increases after ECT were measured in the dentate gyrus. The indicated negative correlation of this effect with antidepressant efficacy warrants replication in data of individual patients.     

Clinical Characteristics and Treatment Outcomes of De Novo Nonconvulsive Status Epilepticus: A Retrospective Study

Background and PurposeNonconvulsive status epilepticus (NCSE) is challenging to diagnose. This study aimed to describe and classify the clinical features and electroencephalography (EEG) findings of patients with de novo NCSE and to correlate them with clinical outcomes.MethodsWe retrospectively reviewed the medical and EEG records of patients admitted to our institution with altered mentation and EEG abnormalities from January 1, 2013 to December 31, 2018. We evaluated premorbid modified Rankin Scale (mRS) scores, underlying disorders, precipitating factors, clinical manifestations, laboratory tests, and outcomes after a 3-month follow-up. Patients who met the Salzburg Consensus Criteria for NCSE were categorized into good-outcome and poor-outcome groups. A good outcome was defined as 1) clinical and electrographic seizures ceasing after treatment, and 2) an mRS score of ≤2 or remaining unchanged during the 3-month follow-up. A poor outcome was defined as 1) death, 2) seizures continuing despite treatment, or 3) a follow-up mRS score of ≥3 in a patient with a premorbid mRS score of ≤2, or a follow-up mRS score that increased in a patient with a premorbid mRS score of ≥3.ResultsThe 48 included patients comprised 37 categorized into the good-outcome group and 11 into the poor-outcome group. The presence of acute metabolic disturbances was significantly correlated with poor outcome (p=0.036), while the other analyzed variables were not significantly correlated with outcomes.ConclusionsAcute metabolic disturbances in NCSE are associated with poor outcomes. Adequate treatment of underlying reversible disorders alongside controlling seizures is critical for patients with NCSE.     

Early Neurological Changes and Interpretation of Clinical Grades in Aneurysmal Subarachnoid Hemorrhage

ObjectivesHunt and Hess (HH) and World Federation of Neurological Surgeons (WFNS) grades are commonly used to report clinical severity of aneurysmal subarachnoid hemorrhage (aSAH). We sought to determine the impact of early neurological changes and the timing of clinical grade assignment on the prognostication accuracy.MethodsWe retrospectively reviewed a cohort of consecutive patients with aSAH who were admitted to an academic center. Patients with confirmed aneurysmal cause were included. Relevant clinical data including daily clinical grades, imaging data and functional outcome were analyzed. Favorable outcome was defined as mRS 0 to 3. Early neurological improvement (ENI) and early neurological deterioration (END) were respectively defined as any improvement or deterioration of HH grades from hospital day 1 to the earliest time from hospital day 2 to 5.ResultsOf 310 patients, 24% experienced early neurological changes from hospital day 1 to 3. For each point increase in HH grades from day 1 to day 3, the odds ratio for worse outcome was 2.57 (95% CI [1.74-3.79]) and for each point decrease in HH grades from day 1 to day 3, the odds ratio for worse outcome was 0.28 (95% CI [0.17-0.47]). Receiver Operating Characteristic curve analysis revealed that clinical grades on day 3 had higher accuracy in predicting worse outcome than clinical grades on day 1.ConclusionEarly changes in neurological status can alter trajectory of hospital course and functional outcome. The prognostic accuracy of the clinical grades from hospital day 3 is significantly greater than those on admission.     

Psychotherapy credibility ratings: Patient predictors of credibility and the relation of credibility to therapy outcome

Abstract

Objective: The current investigation examined the relation between credibility ratings for adult psychotherapies and a variety of patient factors as well as the relation between credibility ratings and subsequent symptom change. Method: A pooled study database that included studies evaluating the efficacy of cognitive and psychodynamic therapies for a variety of disorders was used. For all studies, a three-item credibility scale was administered at session 2. Patient variables at baseline were used to predict early treatment credibility. Results: Early symptom improvement, age, education, and expectation of improvement were all significantly predictive of credibility scores at session 2. In one combined multiple regression model controlling for treatment, study, and early symptom change, age, education, and expectation of improvement remained significantly predictive of credibility scores. Credibility was predictive of subsequent symptom change even when controlling for age, education, expectation of improvement, and early symptom improvement. Conclusions: These findings suggest that age and education, in addition to expectations of improvement and the amount of early symptom improvement, may influence the patient's perceptions of the credibility of a treatment rationale early in the treatment process and that credibility ratings predict subsequent symptom change.     

Predictors of general and health-related quality of life in Parkinson's disease and related disorders including caregiver perspectives

IntroductionOur understanding of the determinants of quality of life (QOL) in people living with Parkinson's disease and related disorders (PDRD) has grown remarkably in the past decade. However, several areas remain understudied including determinants of general vs. health-related QOL, determinants in high-need patients, drivers of perceptions of caregivers vs. patients, and exploration of potential determinants outside of the traditional medical model.MethodsThis was a cross-sectional study of 210 PDRD patients and 175 caregivers who completed a battery of measures regarding general QOL (QOL-Alzheimer's disease; QOL-AD), health-related QOL (Parkinson's disease Questionnaire; PDQ-39), cognitive function, mood, grief, spiritual wellbeing, symptom burden, disease severity, disease stage, overall function, socioeconomic status, and healthcare utilization. Elastic net regularization modeling of variables significantly associated with our outcomes of interest were performed to determine predictors of general QOL, compare predictors of general vs. health-related QOL, and compare predictors of patient and caregiver perspectives on patient general QOL.ResultsGeneral QOL was associated with spiritual wellbeing, depression, cognitive function, presence of a caregiver, and recent emergency department visits. In contrast, health-related QOL was associated with grief, symptom burden, income, disease stage, and utilization of counseling services. Caregiver ratings of patient general QOL were associated with patient symptom burden, patient grief, patient global function, caregiver burden, and caregiver spiritual wellbeing.ConclusionsThere are notable differences in the predictors of general QOL, health-related QOL and caregiver perspectives on patient general QOL. These differences have important implications for clinical research and models of clinical care.     

Good-enough level and dose-effect models: Variation among outcomes and therapists

Objective: The current study examined the good-enough level (GEL) and dose-effect model on three outcome variables: well-being, symptom distress, and life functioning, while accounting for therapist effects. The dose-effect model assumes the rate of change is consistent across clients, and the GEL model assumes that the rate of change will vary according to the total length of treatment. Method: The sample included 13,664 clients who completed 2–100 sessions of therapy. Results: The GEL model was a better fit to the data compared to the dose-effect model for all outcomes. There were fewer changes in life functioning compared to well-being and symptom distress for clients. There were significant therapist effects for changes in symptom distress and life functioning, but not for the rates of change in well-being. Conclusion: Therapists should consider the rates of change for their own clients as well as by outcome.     

A longitudinal view of factors that influence the emotional well-being of family caregivers to individuals with heart failure

Objectives: Caring for community-residing patients with heart failure can affect caregivers’ emotional wellbeing. However, few studies have examined caregivers’ well-being longitudinally, or identified factors associated with positive and negative outcomes. The objective of this longitudinal cohort study was to examine changes in caregivers’ well-being over time, and to identify patient and caregiver factors associated with positive and negative outcomes.

Method: Fifty caregiver/heart failure patient dyads were recruited from an acute care facility and followed in the community. All participants completed surveys at hospital admission and 3, 6 and 12 months later. Caregivers completed assessments of depression symptoms and positive affect and standardized measures to capture assistance provided, mastery, personal gain, social support, participation restriction, and patients’ behavioral and psychological symptoms. From patients, we collected demographic characteristics and health-related quality of life. Individual Growth Curve modelling was used to analyze the data.

Results: Caregivers’ negative and positive emotions remained stable over time. Depression symptoms were associated with higher participation restriction in caregivers. Positive affect was associated with more personal gain and more social support. Patients’ health-related quality of life and their behavioral and psychological symptoms were not significantly associated with caregivers’ emotional outcomes.

Conclusion: Interventions should be offered based on caregivers’ needs rather than patients’ health outcomes, and should focus on fostering caregivers’ feelings of personal gain, assisting them with securing social support, and engaging in valued activities.     

Determinants and impact of alexithymia on quality of life in Parkinson's disease

IntroductionAlexithymia is a neuropsychiatric symptom conceptualized as difficulty identifying and describing feelings. Although associated with other non-motor symptoms, mainly neuropsychiatric, alexithymia may present as an isolated symptom in persons with Parkinson's Disease (PwP). The objective of the study is to identify determinants of alexithymia and its association with quality of life (QoL) in Parkinson's disease.MethodsSubjects with Parkinson's disease were recruited. The following instruments were applied: Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Non-Motor Symptoms Scale (NMSS), Montreal Cognitive Assessment (MoCA), Toronto alexithymia scale (TAS-20) and Parkinson's Disease Questionnaire (PDQ-8). Matched healthy controls were screened using TAS-20. Clinical and demographical variables were compared between alexithymic and non-alexithymic. Regression models were used to find determinants of alexithymia. Impact of alexithymia on QoL was estimated with a linear regression model.Results98 patients were included. 56.1% PwP and 28.8% controls were alexithymic (p < 0.001). Education level (OR 0.86) and NMSS urinary score (OR 1.09) determined alexithymia as well as TAS-20 score. Alexithymia was an independent determinant of QoL.ConclusionsAlexithymia is a prevalent independent non-motor symptom in PwP with impact on QoL. Low education level and urinary symptoms are important determinants of alexithymia.     

Remission as perceived by people with schizophrenia,family members and psychiatrists

IntroductionStudies indicate that patient-rated outcomes and symptomatic remission as defined by the remission in schizophrenia working group rely on different assumptions. The aim of this observational study was to assess symptomatic remission by patients with schizophrenia, family members and psychiatrists and to compare their assessments with standardized criteria and clinical measures.MethodsOne hundred and thirty-one patients with schizophrenia (DSM-IV), family members and psychiatrists assessed remission within the European Group on Functional Outcomes and Remission in Schizophrenia (EGOFORS) project. Symptoms (Positive and Negative Syndrome Scale [PANSS]), functional outcome (Functional Recovery Scale in Schizophrenia [FROGS]), subjective well-being (SWN-K) and demographic characteristics were investigated.ResultsRemission assessed by psychiatrists showed the best accordance with standardized remission (80%), followed by remission assessed by family members (52%) and patients (43%). Only in 18%, patients, relatives and psychiatrists agreed in their assessments. Good subjective well-being was most important for remission estimated by patients, good subjective well-being and symptom reduction by family members, and finally better symptom scores, well-being and functioning by psychiatrists.DiscussionSelf- and expert-rated clinical outcomes differ markedly, with a preference on the patients’ side for subjective outcome. Symptomatic remission as assessed by the standardized criteria plays a secondary role for patients and relatives in daily clinical practice. A more thorough consideration of patients’ and caregivers’ perspectives should supplement the experts’ assessment.     

Predicting depression outcome in mental health treatment: A recursive partitioning analysis

Abstract

Objective: Recursive partitioning was applied to a longitudinal dataset of outpatient mental health clinic patients to identify empirically factors and interactions among factors that best predicted clinical improvement and deterioration in symptoms of depression across treatment. Method: Sixty-two variables drawn from an initial patient survey and from chart review were included as covariates in the analysis, representing nearly all of the demographic, treatment, symptom, diagnostic, and social history information obtained from patients at their initial evaluations. Trees estimated the probability of participants' having depression at their last assessment, improving to a clinically significant degree during treatment, or developing a new onset of significant depressive symptoms during treatment. Results: Initial pain, the presence of anxiety, and a history of multiple types of abuse were risk factors for poorer outcome, even among patients who did not initially have significant depressive symptoms. Conclusions: By examining multiple-related outcomes, we were able to create a series of overlapping models that revealed important predictors across trees. Limitations of the study included the lack of cross-validation of the trees and the exploratory nature of the analysis     

Use of outcome measurements in clinical practice: How specific should one be?

Objective: Progress feedback is often measured with generic instruments that measure common symptoms and generic aspects of functioning. The current study aims to explore the relative usefulness of disorder-specific measures. We hypothesized that disorder-specific instruments reveal more improvement than generic instruments and that the addition of disorder-specific instruments results in better treatment outcomes. Method: We used a cohort of 3419 patients with a depression. As generic measures, we used the BSI or the symptoms distress subscale of the OQ-45. In 946 patients, a specific instrument, the IDS-SR, was added. We compared mean change scores and percentages of clinical significant change. In a matched case control design, we analyzed whether the additional use of the IDS-SR resulted in better treatment outcomes. Results: Mean change scores of both types of instruments were comparable. When comparing clinical significant change, agreement was moderate. We found better outcomes on the generic instruments when both a generic and a disorder-specific instrument were used. Conclusion: In individual treatment of depression, generic and disorder-specific instruments are not interchangeable. The additional use of disorder-specific instruments provides a more complete picture of the patient’s progress than the use of a generic instrument alone.

Clinical or methodological significance of this article: In outcome management often rather generic instruments are used, that do not address the specific symptoms of the primary diagnosis of patients. In daily practice clinicians do not always use the feedback on treatment progress, when they perceive the feedback as not specific or relevant enough. The current study aims to explore the relative usefulness of measures that focus on symptoms that characterize the primary diagnosis of patients with a depression compared to the generic measures. We used a large cohort of existing data of patients of several mental health care organizations that share an application for outcome measurement. First, we compared outcomes of generic instruments and a disorder-specific instrument of a subsample of patients with a depressive disorder that completed both kinds of instruments. Next, we applied a matched case control design to control for differences between patients and analyzed whether the additional use of disorder-specific instruments predicted better outcomes. With this methodology, we tried to optimize both the methodological quality as well as the clinical significance of our research.     

Long term outcome of functional hemispherectomy for refractory epilepsy: Experience from a single center

BackgroundHemispherectomy has an established role as a treatment of last resort in patients with unilateral hemispheric lesions suffering from refractory epilepsy.MethodsSeven patients were evaluated at our Epilepsy Unit. We compared the seizure outcome at 6 months, 1, 2, 5 years post-surgery, as well as at end follow-up (mean 7.1 years) using Engel classification. Reduction of antiepileptic drugs (AEDs) was also assessed utilizing equal time frames.ResultsThe mean age of seizure onset was 5.4 years. Engel I was achieved in 5 patients at 6 months (71.4%). Engel at 1 year was predicted by the Engel at 6 months (p = 0.013) with a similar number of patients being classified as Engel I outcome. Engel at 2 years was also predicted by Engel at 6 months and at 1 year (p = 0.030). At end follow-up only 3 patients (42.9%) remained categorized as Engel I outcome. There was a trend toward a stability in Engel classification. All patients with developmental causes for their epilepsy experienced some deterioration of the surgical outcomes. Conversely, all patients with acquired causes were stable throughout follow-up. Seizure outcome at 6 months was worse in the patients who had post-op complications (p = 0.044). Adult and pediatric populations did not differ significantly in any tested variable.ConclusionsHemispherectomy is a valuable resource for seizure control in properly selected patients. Engel patient's evolution could be predicted at 6 months interval. Hemispherectomy could be considered a useful attitude in difficult cases.     

Pharmacotherapy prior to and in acute haemorrhagic stroke. The use of pharmacotherapy and drugs-associated outcomes in real-world practice – findings from the Polish Hospital Stroke Registry

Background and purposeHaemorrhagic stroke is associated with substantial mortality and disability, thus prevention and appropriate treatment of acute intracerebral haemorrhage is crucial. We aimed to evaluate the use and the early and late outcomes impact of drugs administered before and in acute haemorrhagic stroke in a real-world practice.Material and methodsHaemorrhagic stroke patients hospitalized between 1^st March 2007 and 29^th February 2008 and reported in Polish Hospital Stroke Registry were analysed. Fully anonymous data were collected with standardized, authorized access, web-based questionnaire. Multivariate regression models were used to adjust for case-mix and evaluate the impact of drugs used prior to or in acute haemorrhagic stroke on outcomes. The early outcomes were defined as in-hospital mortality or poor outcome (death or dependency – modified Rankin Scale ≥ 3) at hospital discharge, while late outcomes covered one-year survival.ResultsA total of 3111 haemorrhagic stroke patients (mean age: 68.9 years; females: 46.7%) was reported. The analysis of pharmacotherapy showed low preventive use of hypotensive agents in hypertensive patients, high consumption of antibiotics and still overuse of vasoactive or neuroprotective compounds in acute haemorrhagic stroke. Regression models confirmed expected negative impact on stroke outcomes associated with oral anticoagulants but not antiplatelets and inconsistent impact of statins used prior to or in acute haemorrhagic stroke.ConclusionsPreventive underuse of hypotensive compounds contribute substantially to haemorrhagic stroke risk. The high consumption of antibiotics and neuroprotective or vasoactive compounds in haemorrhagic acute stroke reflect the need to improved quality and evidence-based clinical practice.
