Acute stroke unit care and early neurological deterioration in ischemic stroke

OBJECTIVE: To evaluate the impact that monitored acute stroke unit care may have on the risk of early neurological deterioration (END), and 90-day mortality and mortality-disability. METHODS: Non-randomized prospective study with consecutive patients with acute ischemic stroke (AIS) admitted to a conventional care stroke unit (CCSU), from May 2003 to April 2005, or to a monitored acute stroke unit (ASU) from May 2005 to April 2006. END was defined as an increase in the NIHSS score >or= 4 points in the first 72 hours after admission. RESULTS: END was detected in 19.6% of patients (11.2% of patients admitted to the ASU and 23.8% to the CCSU; p<0.0001). Patients admitted to the ASU received more treatment with intravenous rtPa (13.5% versus 4.2%; p<0.0001), had a shorter length of stay (9.1 [11.0] d versus 13.1 [10.4] d; p<0.0001), lower 90-day mortality (10.2% versus 17.3%; p=0.02), and lower mortality-disability at 90-days (28.4% versus 40.2%; p=0.004) than those admitted to the CCSU. Multivariable analysis showed that ASU admission was a protector for END (OR: 0.37; 95% CI: 0.23-0.62). On admission, higher NIHSS (OR: 1.06; 95% CI: 1.03-1.10), higher glycaemia (OR: 1.003; 95% CI: 1.001-1.006), and higher systolic pressure (OR: 1.01; 95% CI: 1.002-1.017) were independent predictors of END. CONCLUSIONS: END prevention by ASU care might be a key factor contributing to better outcome and decrease of length of stay in patients admitted to monitored stroke units.     

Cooperation and networking in early prevention and intervention and child protection: the importance of evidence-based methods

Prevention, intervention and child protection in early childhood essentially need well-established interdisciplinary systematic networking. Individual, heterogeneous and complex needs of families cannot be met by one profession alone. Successful cooperation of various institutions and professions is based on fixed arrangements and cooperation pathways. Networking has to be systematically established in everyday routine to be able to work in difficult emergency cases of child protection. Only well established cooperation is experienced as a support for the participants of the network and not as an additional complication. Prerequisite for such a development of favorable conditions is an evidence-based knowledge of the impact of different structures of cooperation, relations and conditions. This requires data collection with the aim of further empirically based development of local network structures. Three tools for such surveys have been developed and tested in the field.     

An outcomes approach to stroke care: the importance of teamwork and evidence-based nursing care

The Quality in Acute Stroke Care (QASC) was a cluster randomised control trial (CRCT) which evaluated the effectiveness of evidence-based clinical treatment protocols for the management of fever, hyperglycaemia and swallowing, in conjunction with multidisciplinary team building workshops, and a standardised interactive staff education program (collectively known as the Fever, Sugar, Swallowing (FeSS) intervention) to improve patient outcomes 90-days. We found that patients cared for in stroke units who received our intervention were 15·7% more likely to be alive and independent 90 days following their stroke. They also had significantly: fewer episodes of fever, lower mean temperatures, lower mean blood glucose levels, and better screening for swallowing difficulties.     

Acute stroke care in France: Survey in the 138 stroke units

BackgroundAccording to the French regulation, stroke units (SU) include both an intensive (I-SU) and a non-intensive (NI-SU) component. Their standard operating procedures have been detailed in governmental directives in 2003 and 2007.ObjectivesTo evaluate (i) resources available in French SU, (ii) differences between regions, and between France and the 2 close European countries of similar size, and (iii) to identify avenues for improvement.MethodsWe performed a survey of all French SU, with an online questionnaire, to evaluate available resources and activity. We compared the 17 French regions, and France, with Germany and Italy. We used 2019 as year of reference.ResultsThe 138 French SU, shared 911 I-SU beds; 123 SU (89.1%) answered the questionnaire. The number of I-SU beds per million inhabitants was 13.6 for the whole country, with important differences between regions, ranging from 7.0 (Reunion Island) to 20.9 (Occitanie region). Per million inhabitants, France had fewer I-SU beds than Germany and Italy (13.5 vs. 29.9 and 23.2 respectively), and fewer thrombectomy centres (0.6 vs. 1.8 and 1.0). Per million inhabitants, France had also lower thrombolysis (203 vs. 402) and thrombectomy (104 vs. 194) rates than Germany, but, compared with Italy, similar thrombolysis rates (203 vs. 202) and higher thrombectomy rates (104 vs. 81).ConclusionThere are still avenues for improvement in acute stroke care in France, especially concerning the number and regional repartition of I-SU beds, and access to reperfusion therapies.     

Acute disseminated encephalomyelitis: the importance of early magnetic resonance imaging

The diagnosis of acute disseminated encephalomyelitis (ADEM) is frequently missed or delayed with consequent delay in instituting therapy in the crucial phase of the illness. The role of MRI in the diagnosis of ADEM is well established, however, the value of its early utilization of treatment on the outcome of patients has not been adequately stressed. Three patients with ADEM are described. Delay in the diagnosis of the first was associated with severe sequelae, while in the other two early diagnosis and institution of corticosteroid therapy which was facilitated by MRI, was associated with a better outcome. MRI should be carried out early once the diagosis of ADEM is entertained.     

The polish experience in early stroke care

Stroke units are being organised in Poland since 1997. To ensure easy access to stroke care, 120 specialised units need to be created. There were 23 stroke units in Poland in the year 2000. Only 12 of them fulfilled the criteria of a standard stroke unit. Significant differences in stroke fatality were noted between well- and as yet insufficiently organised units. These results indicate a need for monitoring the implementation of the basic standards in stroke units.     

Organization of medical care in acute stroke: importance of a good network

Stroke is a medical emergency which requires hospital care. Therapeutic and effective organizative measures, such as thrombolysis and stroke units, are available, but early attention is required, as the benefits are time dependent (therapeutic window). To achieve this objective, a high level of organization and coordination is required between the various steps of care. The chain of attention in acute stroke (from symptom onset till stroke unit admission) is a complex process. The main points are reviewed: delay in attention, knowledge and attitude towards stroke, emergency transportation, neurological attention, educational campaigns, clinical protocols and pathways, stroke codes, and existing resources for care. The organization must be modified to have the resources for care necessary for attending acute stroke available, if we want to achieve the real objective of maximum benefit for our patients as set out in the Declaration of Helsingborg.     

Acute neurological stroke care in Europe: results of the European Stroke Care Inventory

Following the 1997 Recommendations of the EFNS Task Force on Acute Neurological Stroke Care (European Journal of Neurology, 1997: 4 :435–441) a European Inventory was undertaken to assess the development of acute stroke care in the EFNS member countries and to give an estimate of the needs based on 1997 data. All 30 members of the EFNS Stroke Scientist Panel were asked to complete a questionnaire on acute stroke epidemiology as well as acute stroke care in their country. Data were based either on national surveys, hospital statistics, or estimates given on the basis of extrapolation of regional studies, or other defined sources. Specialist estimates were also taken into account where no other data source was available. Data from 22 countries were received and referred to almost one million strokes occurring per year in a population of over 500 million. Most epidemiological data confirmed an east–west gap known from previous studies. These included rates that, in eastern countries, were higher for incidence, stroke as a leading cause of death, and 30-day case-fatality, and rates that were lower for overall hospitalization or availability of CT scanning. East–west differences were not seen for the total number of acute stroke units or the number of acute stroke units set up within neurological hospital departments, nor for most other quality indicators of acute stroke care with the exception of technological standards in some countries. The higher rates for 30-day case-fatality in eastern Europe (mostly above 20%) compared with western Europe (mostly below 20%) are probably caused by a case mix with more severe ischemic strokes and a higher percentage of cerebral haemorrhages admitted for acute care in eastern Europe. This is probably due to the higher prevalence of the most common risk factors for stroke in these countries which tend to result in more severe strokes. This, therefore, underlines the need for stroke prevention programmes especially in eastern Europe. This epidemiological east–west gap is not reflected by most quality indicators for acute stroke care, e.g. total number of acute stroke units available within each country. Most eastern European countries have a well-developed neurological care system for acute stroke but still have urgent technological and socioeconomical needs. The leading role of clinical neurology in acute stroke care is visible in most but not all European countries.     

Mental health care for young people: early intervention in psychosis

During the last 15 years, much progress in early interventions (Els) focusing on psychosis in the young people has been made, and new revelations about psychotic disorder including schizophrenia have come out. Furthermore, findings from clinical epidemiology in the general population and clinical genetics of psychiatric diseases have revealed the "trajectories" before the onset of psychosis. Current state and challenge of Els in the first-episode psychosis (FEP) and high risk state (HRS) (putatively prodromal state) for psychosis will be selectively overviewed in this article. Although Els in FEP shorten the duration of untreated psychosis and improve the short-term outcome, it would be required to sustain the EL effects for a long time. Els in HRS also prove fruitful, but predictor of transition to psychosis must be established for the clinical practice. Furthermore, Els in the earlier HRS targeting at the cognitive dysfunction and negative rather than positive symptoms under ethical consideration will improve psychosocial impairments. Clinical staging concept using in general medicine for the serious physical diseases might enable an individualized medicine in psychiatric EIs.     

Citrobacter brain abscesses in neonates: early surgical intervention and review of the literature

Purpose

Citrobacter koseri, a facultatively anaerobic, lactose-fermenting, gram-negative bacilli, has a strong propensity to form cerebral abscesses. C. koseri brain abscesses can be a devastating disease of infancy and childhood with more than 30?% succumbing to the disease and more than 50?% suffering severe neurological deficits.

Methods

This study represents a retrospective review of two cases of C. koseri brain abscesses along with a review of the literature regarding diagnosis and treatment.

Results

Early aggressive surgical and medical treatment resulted in favorable outcomes for two children with C. koseri brain abscesses, one diagnosed at 6?weeks of age and the other at 2?months of age.

Conclusion

C. koseri brain abscesses can be devastating and have been associated historically with significant morbidity and mortality. However, favorable outcomes are possible, and aggressive surgical and medical management should be considered for patients with C. koseri abscesses.     

Acute subcortical stroke and early serotonergic modification: a IDAP study

The intensity dependence of the auditory-evoked potentials (IDAP) is inversely related to serotonergic tone. Depression is frequently observed after stroke, associated with cognitive impairment and increased mortality. Aim of this study was to investigate the serotonergic tone in acute stroke patients by IDAP. Consecutive patients with an acute stroke admitted in our stroke unit were evaluated using clinical and instrumental examinations and compared with healthy controls. The IDAP was calculated as the linear amplitude/stimulus intensity function (ASF) slope, by measuring the peak-to-peak amplitude of Nl-P2 on four blocks of different stimulus intensities. Twenty patients were enrolled; 11 had a right brain infarction; nine had depressive symptoms (DS). The ASF slope of the auditory-evoked potentials was markedly increased in stroke patients compared with controls ( P  = 0.021). Stroke patients with DS had a significant steeper ASF slope than controls ( P  = 0.017). There was no statistical difference in ASF slope between stroke patients without DS and controls. Post-stroke depression pathophysiology is still debated. Our study suggests that in acute stroke patients with DS, there is a direct involvement of the serotonergic system, regardless the degree of disability and the site of the lesion.
