RESUMO

To assess clinical impact and perform cost-consequence analysis of the broadest multiplex PCR panels available for the rapid diagnosis of bloodstream infections (BSI). Single-center, randomized controlled trial conducted from June 2019 to February 2021 at a French University hospital with an institutional antimicrobial stewardship program. Primary endpoint was the percentage of patients with optimized antimicrobial treatment 12 h after transmission of positivity and Gram stain results from the first positive BC. This percentage was significantly higher in the multiplex PCR (mPCR) group (90/105 = 85.7% %, CI95% [77.5 ; 91.8] vs. 68/107 = 63.6%, CI95% [53.7 ; 72.6]; p < 10- 3) at interim analysis, resulting in the early termination of the study after the inclusion of 309 patients. For patients not optimized at baseline, the median time to obtain an optimized therapy was much shorter in the mPCR group than in the control group (6.9 h, IQR [2.9; 17.8] vs. 26.4 h, IQR [3.4; 47.5]; p = 0.001). Early optimization of antibiotic therapy resulted in a non-statistically significant decrease in mortality from 12.4 to 8.8% (p = 0.306), with a trend towards a shorter median length of stay (18 vs. 20 days; p = 0.064) and a non-significant reduction in the average cost per patient of €3,065 (p = 0.15). mPCR identified all the bacteria present in 88% of the samples. Despite its higher laboratory cost, the use of multiplex PCR for BSI diagnosis leads to early-optimised therapy, seems cost-effective and could reduce mortality and length of stay. Their impact could probably be improved if implemented 24/7.

RESUMO

AIM: To analyse the diagnostic performance of bone and leukocyte scintigraphy for periprosthetic joint infection before excluding the test from routine practice, and to analyse the possible benefit of bone marrow scintigraphy in inconclusive cases. MATERIALS AND METHODS: From 2012 to 2018, all patients with a total hip or knee arthroplasty who had a bone and leukocyte scintigraphy performed and underwent revision surgery were included. Bone marrow scintigraphy was indicated only in cases in which bone and leukocyte scintigraphy were inconclusive. Diagnosis of periprosthetic joint infection was confirmed by positive intraoperative cultures after revision surgery. RESULTS: A total of 105 patients were included. Eighteen patients had total hip arthroplasties (18.1%) and 86 had total knee arthroplasties (81.9%). Mean age was 74 years. Nineteen cases were diagnosed with a periprosthetic joint infection. Bone and leukocyte scintigraphy had 64% sensitivity and 97% specificity. Bone marrow scintigraphy increased sensitivity and specificity to 88% and 100%, respectively. CONCLUSION: Bone and leukocyte scintigraphy possesses high sensitivity and specificity for the diagnosis of chronic periprosthetic joint infection. The additional use of bone marrow scintigraphy significantly increases diagnostic performance. For these reasons, bone scintigraphy is reserved for inconclusive cases of chronic periprosthetic joint infection.

RESUMO

The last few years have seen a significant increase in the number of large-scale sequencing projects generating whole genome databases. These sequence databases can be surveyed (genome sequence survey) for tandem repeats as an alternative means to develop microsatellites for monitoring and selecting natural populations and cultivars of Jatropha curcas. A total of 100 tandem repeats were revealed from mining 368 genomic surveyed sequences available in the Kazusa DNA Research Institute database. Twenty microsatellite sequences were successfully amplified, resulting in repeatable and scorable polymerase chain reaction products. Genotyping of J. curcas accessions from the Guatemalan population revealed 18 polymorphic loci. The average number of alleles per locus was 6.9, and allelic sizes ranged from 94 to 299 bp. Expected and observed heterozygosities ranged from 0.118 to 0.906 and from 0.082 to 0.794, respectively. Polymorphic information content values ranged from 0.114 (JcSSR-34) to 0.886 (JcSSR-33) with an average of 0.627. Analysis with Micro-Checker indicated few null alleles for locus JcSSR-37 in Guatemalan populations, which may be a possible cause of its deviation from Hardy-Weinberg equilibrium, even after Bonferroni's correction. No loci showed significant linkage disequilibrium. These microsatellite loci are expected to be valuable molecular markers in J. curcas because they show high levels of polymorphism and heterozygosity.

RESUMO

INTRODUCTION: Morbidity remains high among patients who undergo successful mechanical thrombectomy (MT) for anterior circulation large vessel occlusion (LVO). Stress hyperglycemia worsens the prognosis after acute ischemic stroke (AIS), but aggressively treating hyperglycemia does not improve the outcome. There is no consensus on how to best manage glycemia after AIS. Glycemic variability (GV) reflects glycemic fluctuations over time and could be the culprit. We aimed to elucidate how GV impacts outcome of AIS patients treated with MT. PATIENTS AND METHODS: This was a single-center retrospective study. We consecutively included AIS patients who received MT for anterior circulation LVO. We recorded discrete blood glucose measurements within the first 24 hours post thrombectomy, from which we calculated two measures of GV: standard deviation (SD) and coefficient of variation. Univariate and multivariate analyses were conducted to identify predictors of poor functional outcome (modified Ranking scale score 3-6) and mortality at 3-month follow-up. RESULTS: We included 657 patients. Patients with poor functional outcome (42.5%) and patients that died (14.8%) had significantly higher GV as measured by SD. In a multivariable model adjusted for confounders, higher SD was associated with mortality -adjusted odds ratio: 1.020 (95% CI 1.001-1.040)- but not with functional outcome -adjusted odds ratio for modified Ranking scale score 3-6: 1.007 (95% CI 0.990-1.025)-. CONCLUSIONS: Our results suggest that higher GV after MT for anterior circulation AIS is an independent risk factor for 3-month mortality. Future trials should evaluate the benefit of reducing GV in this setting.


TITLE: Variabilidad glucémica tras trombectomía mecánica en el ictus isquémico agudo de la circulación anterior.Introducción. La morbilidad de los pacientes con ictus isquémico agudo (IIA) sometidos a trombectomía mecánica (TM) exitosa permanece alta. La hiperglucemia empeora el pronóstico tras un IIA, pero tratarla agresivamente no mejora los resultados. No existe consenso sobre el tratamiento óptimo de la glucemia después de un IIA. La variabilidad glucémica (VG), que refleja las fluctuaciones glucémicas a lo largo del tiempo, puede ser un factor importante. Nuestro objetivo fue investigar cómo la VG afecta el resultado de pacientes con IIA tratados con TM. Pacientes y métodos. Realizamos un estudio retrospectivo unicéntrico que incluyó a pacientes con IIA que recibieron TM para la oclusión de un gran vaso de la circulación anterior. Se registraron mediciones discretas de glucemia en las primeras 24 horas postrombectomía, a partir de las cuales se calcularon dos medidas de VG: desviación estándar y coeficiente de variación. Se realizó un análisis univariado y multivariado para identificar predictores de resultado funcional desfavorable (escala de Rankin modificada: 3-6) y mortalidad a los tres meses. Resultados. Se incluyó a 657 pacientes. Los que tenían una puntuación en la escala de Rankin modificada = 3 (42,5%) y los fallecidos (14,8%) tuvieron una VG significativamente mayor medida por desviación estándar. En un modelo multivariado, una mayor desviación estándar se asoció de forma independiente con la mortalidad ­odds ratio ajustada: 1,02 (intervalo de confianza al 95%: 1,001-1,04)­ pero no con el resultado funcional ­odds ratio ajustada de la escala de Rankin modificada = 3: 1,007 (intervalo de confianza al 95%: 0,99-1,025)­. Conclusiones. Nuestros resultados sugieren que una mayor VG tras la TM para el IIA de la circulación anterior es un factor de riesgo independiente de mortalidad a los tres meses. Los futuros ensayos deben evaluar el beneficio de reducir la VG en este contexto.

RESUMO

AIM: To measure carotid intima-media thickness (cIMT) in obese, overweight and normal-weight Portuguese adolescents, to evaluate the association between body weight early signs of atherosclerosis. METHODS: Cross-sectional study, enrolling 150 adolescents (50 normal weight, 50 overweight and 50 obese) with mean age of 12.9 years. All underwent clinical, analytical and carotid common artery ultrasonographic evaluation. RESULTS: After adjusting for systolic blood pressure and plasma High-density lipoprotein, Low-density lipoprotein and Triglycerides levels, higher mean cIMT values were observed in both overweight and obese patients, when compared to normal-weight group. Moreover, adolescents with metabolic syndrome (MS) had greater cIMT [normal-weight: cIMT mean 0.418 mm (95% confidence intervals (95% CI) 0.399-0.437); overweight: 0.461 mm (95% CI: 0.444-0.477); obese: 0.472 mm (95% CI: 0.455-0.488); MS: 0.482 mm (95% CI: 0.444-0.520) p = 0.001]. When normal-weight and overweight adolescents were exclusively compared, differences in cIMT remained significant (p < 0.001). cIMT was positively correlated with body mass index (BMI) (r = 0.439, p < 0.001), waist circumference (r = 0.301, p = 0.018) and diastolic blood pressure (r = 0.266, p = 0.001). CONCLUSIONS: We have shown that cIMT is positively associated with BMI increase in adolescents, even in moderate overweight ranges, independent of age, gender, systolic blood pressure and plasma lipid concentrations.

RESUMO

BACKGROUND: Apical hypertrophic cardiomyopathy (AHCM) is a rare cardiomyopathy, in which hypertrophy occurs predominantly in the ventricular apex, and in some cases with a high risk of sudden cardiac death. OBJECTIVE: The aim of this paper is to present a case series of patients with AHCM and describe their main clinical, echocardiographic and electrocardiographic characteristics, the recommendation for an implantable cardioverter-defibrillator (ICD) and the frequency of sudden cardiac death (SCD). METHODS: A retrospective case series was conducted at the referral center of a federal teaching hospital, between the years 2005 to 2020, involving patients with an echocardiographic diagnosis of AHCM. The parameters of the American College of Cardiology and the European Society of Cardiology were used to assess the risk of SCD. RESULTS: A total of 11 individuals were assessed with a mean age of 55.3 years, mean follow-up of 41.2 months, most of whom were symptomatic at diagnosis (72.7%). The most frequent symptom was dyspnea (27.3%). A family history of SCD was described in 45.5% of cases. Due to a high risk of SCD, four patients received ICDs. One patient presented sudden cardiac death after having refused the ICD. CONCLUSIONS: Symptoms and alterations in the imaging exams are significant factors in the clinical and prognostic assessment of patients with AHCM.

RESUMO

OBJECTIVE: To assess the impact of corticosteroids on inflammatory and respiratory parameters of patients with COVID-19 and acute respiratory distress syndrome (ARDS). METHODS: Longitudinal, retrospective, observational study conducted in an ICU of a second level hospital. Adult patients with COVID-19 were included. Baseline characteristics, data on SARS-CoV-2 infection, treatment received, evolution of respiratory and inflammatory parameters, and ICU and hospital stay and mortality were analyzed. RESULTS: A total of 27 patients were included, 63% men, median age: 68.4 (51.8, 72.2) years. All patients met ARDS criteria and received MV and corticosteroids. After corticosteroids treatment we observed a reduction in the O2 A-a gradient [day 0: 322 (249, 425); day 3: 169 (129.5, 239.5) p<0.001; day 5: 144 (127.5, 228.0) p<0.001; day 7: 192 (120, 261) p=0.002] and an increase in the pO2/FiO2 ratio on days 3 and 5, but not on day 7 [day 0: 129 (100, 168); day 3: 193 (140, 236) p=0.002; day 5: 183 (141, 255) p=0.004; day 7: 170 (116, 251) p=0.057]. CRP also decreased on days 3 and 5 and increased again on day 7 [day 0: 16 (8.6, 24); day 3: 3.4 (1.7, 10.2) p<0.001; day 5: 4.1 (1.4, 10.2) p<0.001; day 7: 13.5 (6.8, 17.3) p=0.063]. Persistence of moderate ARDS on day 7 was related to a greater risk of poor outcome (OR 6.417 [1.091-37.735], p=0.040). CONCLUSIONS: Corticosteroids appears to reduce the inflammation and temporarily improve the oxygenation in COVID-19 and ARDS patients. Persistence of ARDS after 7 days treatment is a predictor of poor outcome.

RESUMO

PURPOSE: To describe the epidemiology of critical disease in HIV-infected patients during the current highly active antiretroviral therapy (HAART) era and to identify hospital mortality predictors. METHODS: A longitudinal, retrospective observational study was made of HIV-infected adults admitted to the ICU in two Spanish hospitals between 1 January 2000 and 31 December 2014. Demographic and HIV-related variables were analyzed, together with comorbidities, severity scores, reasons for admission and need for organ support. The chi-squared test was used to compare categorical variables, while continuous variables were contrasted with the Student's t-test, Mann-Whitney U-test or Kruskal-Wallis test, assuming an alpha level=0.05. Multivariate logistic regression analysis was used to calculate odds ratios for assessing correlations to mortality during hospital stay. Joinpoint regression analysis was used to study mortality trends over time. RESULTS: A total of 283 episodes were included for analyses. Hospital mortality was 32.9% (95%CI: 21.2-38.5). Only admission from a site other than the Emergency Care Department (OR 3.64, 95%CI: 1.30-10.20; p=0.01), moderate-severe liver disease (OR 5.65, 95%CI: 1.11-28.87; p=0.04) and the APACHE II score (OR 1.14, 95%CI: 1.04-1.26; p<0.01) and SOFA score at 72h (OR 1.19, 95%CI: 1.02-1.40; p=0.03) maintained a statistically significant relationship with hospital mortality. CONCLUSIONS: Delayed ICU admission, comorbidities and the severity of critical illness determine the prognosis of HIV-infected patients admitted to the ICU. Based on these data, HIV-infected patients should receive the same level of care as non-HIV-infected patients, regardless of their immunological or nutritional condition.

RESUMO

INTRODUCTION: Rapidly destructive osteoarthritis (RDO) of the hip is characterized by rapid joint destruction with no specific underlying diagnosis. Diagnostic protocols and algorithms to rule out other possible causes of the rapid destruction of the hip have not been described. Furthermore, microbiological diagnostic procedures in the medical field have dramatically changed since RDO was first described. CASE REPORT: We report the case of bilateral RDO in a Caucasian 84-year-old female treated with a bilateral total hip replacement and propose an etiology for this condition. This is the first case that specifically mentions obtaining cultures intraoperatively as a definitive diagnostic method. It is also a rare case as it describes a patient with the bilateral rapid destruction of the hip joints. CONCLUSION: Total hip arthroplasty remains as the gold-standard for treatment of RDO due to clinical severity and radiographic findings. All current clinical guidelines do not recommend using a one stage total hip replacement in an active infected site due to high risk of early prosthetic joint infection. The evidence of an infectious etiology in all or some cases of RDO would have large-scale implications regarding diagnosis and treatment of this condition.

RESUMO

Widespread gas venting along the Cascadia margin is investigated from acoustic water column data and reveals a nonuniform regional distribution of over 1100 mapped acoustic flares. The highest number of flares occurs on the shelf, and the highest flare density is seen around the nutrition-rich outflow of the Juan de Fuca Strait. We determine ∼430 flow-rates at ∼340 individual flare locations along the margin with instantaneous in situ values ranging from ∼6 mL min-1 to ∼18 L min-1. Applying a tidal-modulation model, a depth-dependent methane density, and extrapolating these results across the margin using two normalization techniques yields a combined average in situ flow-rate of ∼88 × 106 kg y-1. The average methane flux-rate for the Cascadia margin is thus estimated to ∼0.9 g y-1m-2. Combined uncertainties result in a range of these values between 4.5 and 1800% of the estimated mean values.

RESUMO

INTRODUCTION: Neurovascular ultrasound is a non-invasive, portable and fast imaging method that, when performed by an experienced neurosonologist, offers reliable and reproducible information on the morphological and hemodynamic status of cervical and intracranial vessels. AIM: To review the available evidence regarding the use of this tool in the approach to acute stroke. DEVELOPMENT: Neurovascular ultrasound can be used in one of two ways: diagnostic and therapeutic. Considering the low recanalization rates of internal carotid artery and proximal medial cerebral artery occlusions with intravenous recombinant tissue plasminogen activator (r-tPA), neurovascular ultrasound used shortly in Emergency Department may help to select patients that could benefit from endovascular therapy. Moreover, ultrasound monitorization during intravenous r-tPA treatment allows the analysis of the pattern of arterial recanalization. Cervical ultrasound allows the assessment of the stenosis degree and the composition/surface of an arterial plaque that could, for instance, reveal earlier a candidate for carotid intervention. Finally, the therapeutic potential of ultrasound is also being investigated. Sonothrombolysis and sonolysis, that combine ultrasound technology with r-tPA and use exclusively the ultrasound to lyse the clot, respectively, showed promising results. CONCLUSION: Neurovascular ultrasound has greatly expanded to assume an important role in the study of cerebrovascular disorders.


TITLE: Ecografia neurovascular en urgencias: aspectos diagnosticos y terapeuticos.Introduccion. La ecografia neurovascular es una tecnica de diagnostico por imagenes rapida, portatil e incruenta que en manos de un ecografista experimentado aporta informacion reproducible y fiable acerca del estado hemodinamico y morfologico de los vasos craneales y cervicales. Objetivo. Revisar los datos disponibles sobre el uso de esta herramienta en el abordaje del ictus isquemico agudo. Desarrollo. La ecografia neurovascular se divide en dos modalidades de uso: diagnostica y terapeutica. A la luz de los bajos porcentajes de recanalizacion de las oclusiones de la arteria carotida interna y del segmento proximal de la arteria cerebral media logradas por el activador del plasminogeno tisular recombinante (r-tPA) por via intravenosa, el uso diligente de la ecografia neurovascular en el servicio de urgencias ayuda a dirimir que pacientes son susceptibles de beneficiarse del tratamiento endovascular. Asimismo, la vigilancia ecografica durante el curso del tratamiento con el r-tPA permite analizar la evolucion de la recanalizacion arterial. La ecografia cervical permite valorar el grado de estenosis y la composicion o la superficie de la placa arterial, extremos que, por ejemplo, pueden indicar la idoneidad de una intervencion carotidea. Por ultimo, tambien se esta investigando el potencial terapeutico de la ecografia. La sonotrombolisis y la sonolisis, la primera combinando el r-tPA con las ondas ultrasonicas y la segunda sirviendose unicamente de ellas como medio para lisar el trombo, han evidenciado hasta el momento resultados alentadores. Conclusion. La ecografia neurovascular ha progresado enormemente hasta adquirir un protagonismo destacado en el estudio de los trastornos cerebrovasculares.

RESUMO

INTRODUCTION: Pain treatment for patients with hip fracture has been based on the use of nonsteroidal anti-inflammatories and opioid derived drugs. These medications have been associated with multiple adverse effects. Fascia iliaca block is a recent pain management alternative for these patients. The objective of this study was to evaluate the effectiveness of fascia iliaca block performed in the emergency room (ER) for patients over 65years of age with hip fracture. MATERIALS AND METHODS: A cohort of 216 patients, from January to December 2016, was studied prospectively. Analyzed variables were: pain upon arrival at ER, pain after fascia iliaca block, need for rescue medication, protocol compliance, delay in analgesia administration and delay for surgery. RESULTS: Differences between visual analogue scale (VAS), before and after the fascia iliaca block, were statistically significant (P<.001). Pre-block VAS recorded was 6.16 (SD=2.82). The mean VAS reduction after the block was 2.99 (95%CI: 2.45-3.53%). Twenty-six percent of patients required morphine as rescue medication in the first 8hours after diagnosis. Compliance with protocol administration was of 84%. Fascia iliaca block was performed in a mean time of 16minutes (SD=10.33) after diagnosis. The median delay for surgery was 1 day (RIQ 25-75%: 1-2). CONCLUSION: Fascia iliaca block is a reproducible, safe and effective technique for pain management. It is a keystone in pain treatment for patients with a proximal femur fracture at our institution. Other objectives in our pain management protocol include early analgesia administration and reduction of time to surgery.

RESUMO

Prostaglandin-H synthase exists in two isoforms, PGHS-1 and PGHS-2. PGHS-1 is present and is constitutively expressed in most cells and tissues, whereas PGHS-2 is mainly thought to mediate inflammation. Selective prostaglandin-H synthase-2 (or cyclooxygenase-2) inhibitors have been shown to be potent antiinflammatory agents with fewer side effects than currently marketed nonsteroidal antiinflammatory drugs (NSAIDs). This review addresses the main classes of the selective PGHS-2 inhibitors whose selectivity is documented by supporting PGHS-1 and PGHS-2 enzyme data. In addition, we also describe our experience in design, synthesis and pharmacological in vivo evaluation of new 1,2-benzodioxole derivatives as candidate of the selective PGHS-2 inhibitors, with special attention to molecular dynamics simulations of these derivatives attached to the active site of PGHS-2.

RESUMO

Abrogation of the normal p53 pathway is the most common molecular alteration in human cancer. p53 Gene status can be potentially assessed through the expression of proteins known to be activated by the wild-type p53 (wt p53) system, such as mdm2 and p21Waf1/Cip1. In this study, the frequency of mdm2, p21Waf1/Cip1, and p53 protein expression was investigated using immunohistochemistry (IHC) in 88 colorectal carcinomas (CRCs). The relationship between these expressions and p53 status was examined. p53 status and the immunophenotypes characterizing these tumors were correlated with standard prognostic variables. Mutation of p53 was detected using single-strand conformational polymorphism (SSCP) analysis and sequencing. Concordance between p53 gene status and p53 immunoreactivity was seen in 62 of 88 (70.45%) carcinomas. Mdm2 expression was found in 22 of 45 (48.88%) and 5 of 43 (11.62%) of the tumors with wt p53 and mutated p53 (P<0.0001), respectively. Predominantly, higher p21Waf1/Cip1 expression was associated with wt p53 (P<0.001). All wt p53 cases that expressed mdm2 also expressed p21Waf1/Cip1. These results suggest that there is a subgroup of CRCs in which p53 is functionally active, inducing transcription of mdm2 and Waf1/Cip1. Their combined evaluation may provide important clues for planning adjuvant systemic therapy and gene therapy based on the restitution of p53 function. However, no significant association was found between the immunophenotypes and the standard prognostic variables investigated.

RESUMO

PURPOSE: The effect of contact transscleral diode cyclophotocoagulation (TDC) on intraocular pressure (IOP) and its safety was determined in eyes with intractable glaucoma. METHODS: The charts of 41 consecutive patients (43 eyes) who underwent the laser procedure were reviewed. After surgery, data were collected from chart entries at I hour, 1 day, 4 to 6 weeks, 4 to 6 months, and at the final visit (6-24 months). Mean differences in IOP before and after treatment were compared using the paired Student t test. Associated complications also were assessed. RESULTS: The mean +/- standard deviation follow-up period was 11.9+/-5.3 months (range, 6-24 months). One patient who died after 1 month of follow-up and another patient with neovascular glaucoma who underwent an anterior chamber washout 1 week after laser to treat an uncontrolled IOP spike were excluded from the study. Repeat treatment was done in 12 (28%) eyes. At each follow-up visit postoperatively, a significant reduction from preoperative IOP was obtained (mean reduction of 50% at the final visit). At the final visit, 64% of patients achieved an IOP of <22 mmHg and a reduction of > or =20%. An IOP spike occurred in three (7%) eyes. Long-term complications included loss of vision (> or =2 lines) in eight (22%) patients, corneal decompensation in one (2%), phthisis bulbi in one (2%), and corneal graft rejection in one (2%). CONCLUSION: Although effective IOP reduction was demonstrated in eyes with intractable glaucoma after TDC, a significant proportion (26%) of eyes had severe long-term complications.

RESUMO

BACKGROUND: Recent studies in acute stroke patients have shown an association between body temperature and prognosis. OBJECTIVES: Our objective was to assess the effects of cooling when applied to patients with acute ischaemic stroke or primary intracerebral haemorrhage. SEARCH STRATEGY: We searched the Cochrane Stroke Group's trial register (last searched in March 1999), plus MEDLINE searched up to November 1998 and EMBASE searched from January 1980 to November 1998. We contacted investigators, pharmaceutical companies and manufacturers of cooling equipment in this field. SELECTION CRITERIA: All completed randomised controlled trials or controlled clinical trials, published or unpublished, where cooling therapy (therapy given by physical devices or antipyretic drugs primarily to lower body temperature independently of basal temperature at the beginning of treatment) was applied up to two weeks of an acute ischaemic stroke or primary intracerebral haemorrhage. DATA COLLECTION AND ANALYSIS: Two reviewers independently searched for relevant trials. MAIN RESULTS: No randomised trials or controlled trials were identified; one placebo-controlled trial of metamizol is currently underway. REVIEWER'S CONCLUSIONS: There is currently no evidence from randomised trials to support the routine use of physical or chemical cooling therapy in acute stroke. Since experimental studies showed a neuroprotective effect of hypothermia in cerebral ischaemia, and hypothermia appears to improve the outcome in patients with severe closed head injury, trials with cooling therapy in acute stroke are warranted.
