    Cognitive-behavior therapy for Japanese patients with panic disorder: Acute phase and one-year follow-up results

    PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 3 2008
    Yumi Nakano md
    Aim:, The aim of this paper is to report the outcomes and follow-up data of our cognitive behavioral therapy program for Japanese patients with panic disorder and to examine the baseline predictors of their outcomes. Methods:, Seventy outpatients with panic disorder with or without agoraphobia were treated with manualized group cognitive behavioral therapy. Results:, Fourteen patients (20%) did not complete the program. Among the completers, the average Panic Disorder Severity Scale score fell from 12.8 at baseline to 7.1 post-therapy (44.7% reduction). This effectiveness was sustained for 1 year. While controlling for the baseline severity, the duration of illness and the baseline social dysfunction emerged as significant predictors of the outcome. Conclusions:, Our data suggest that group cognitive behavioral therapy for panic disorder can bring about as much symptom reduction among Japanese patients with panic disorder as among Western patients.

    Usefulness of Serial Assessment of Natriuretic Peptides in the Emergency Department for Patients With Acute Decompensated Heart Failure

    CONGESTIVE HEART FAILURE, Issue 4 2008
    Salvatore DiSomma MD
    The value of natriuretic peptides, both B-type natriuretic peptide (BNP) and N-terminal prohormone brain natriuretic peptide (NTproBNP), for determining diagnosis, severity, and prognosis of emergency department (ED) patients with acute decompensated heart failure (ADHF) has been well documented. Emerging data support the hypothesis that repeated natriuretic peptide determinations in the acute phase of ADHF may assist in confirming the diagnosis, monitoring drug therapy, and evaluating the adequacy of patient stabilization. Data from the authors' group demonstrate that in patients admitted to the ED for acute dyspnea, serial NTproBNP measurement at admission and 4, 12, and 24 hours later was useful in confirming the diagnosis of ADHF compared with patients with chronic obstructive pulmonary disease. Moreover, in the same patients receiving intensive intravenous diuretic therapy, there was a progressive reduction of NTproBNP blood levels from hospitalization to discharge (P<.001), accompanied by clinical improvement and stabilization of heart failure. More recently, the authors also demonstrated that in ADHF patients improving with diuretics, a progressive reduction in BNP levels was observed, starting 24 hours after ED admission and continuing until discharge. Comparing BNP and NTproBNP, there was a significant correlation between NTproBNP and BNP levels but not between NTproBNP's and BNP's percent variation compared with baseline. In ADHF, serial ED measurements of BNP are useful for monitoring the effects of treatment. A reduction in BNP from admission to discharge is indicative of clinical improvement. [source]


    Folic acid efficacy as an alternative drug added to sodium valproate in the treatment of acute phase of mania in bipolar disorder: a double-blind randomized controlled trial

    ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2009
    A. H. Behzadi
    Objective:, The purpose of this study was to evaluate the efficacy of adding folic acid to sodium valproate in the acute phase of mania. Method:, Following a double-blind randomized controlled trial, 88 clinically manic patients with diagnosis of type I bipolar disorder (BID) were divided randomly into two groups (case and control). The case group was treated with folic acid and sodium valproate and the control group with sodium valproate and placebo. The severity of mania was assessed using the Young Mania Rating Scale (YMRS) at the beginning and end of the first, second and third weeks of the study. Results:, The case group's mean manic YMRS measurements (SD) before the initiation of therapy and in the first, second and third weeks of treatment were 34.0 ± 7.7, 26.7 ± 2.1, 18.1 ± 2.1 and 7.1 ± 0.9 respectively. The control group's measurements were 34.7 ± 3.8, 27.3 ± 2.3, 20.7 ± 2.5 and 10.1 ± 1.1. There was a statistically significant difference in YMRS scaling results between the case and control groups after 3 weeks of treatment (7.1 ± 0.9 vs. 10.1 ± 1.1, P = 0.005). Conclusion:, Based on our findings, folic acid seems to be an effective adjuvant to sodium valproate in the treatment of the acute phase of mania in patients with bipolar disorder. [source]


    Treatment of varicella-zoster virus and postherpetic neuralgia

    DERMATOLOGIC THERAPY, Issue 3 2000
    Daniel A. Carrasco
    ABSTRACT: Chickenpox is mostly a disease of childhood; shingles usually affects the elderly, but any age group may be afflicted. Although several proved pharmacologic agents are known to be efficacious in the acute phase of varicella-zoster infections, only three are FDA approved for use in immunocompetent zoster patients and one for the use in primary varicella infections. Ongoing studies with immunocompromised patients are determining whether higher doses of newer oral antivirals will be effective. While a cure for postherpetic neuralgia has not been found, effective treatment to reduce its duration and severity means early implementation of newer antiviral agents. While corticosteroids do not prevent postherpetic neuralgia, they do improve the quality of life when used in combination with acyclovir. Often, symptomatic relief with narcotics, topical anesthetics, and tricyclic antidepressants are necessary. [source]


    A cardiologist view of vascular disease in diabetes

    DIABETES OBESITY & METABOLISM, Issue 4 2008
    Christopher J. Lockhart
    Diabetes mellitus is a potent risk factor for the development of a wide spectrum of cardiovascular (CV) complications. The complex metabolic milieu accompanying diabetes alters blood rheology, the structure of arteries and disrupts the homeostatic functions of the endothelium. These changes act as the substrate for end-organ damage and the occurrence of CV events. In those who develop acute coronary syndromes, patients with diabetes are more likely to die, both in the acute phase and during follow-up. Patients with diabetes are also more likely to suffer from chronic cardiac failure, independently of the presence of large vessel disease, and also more likely to develop stroke, renal failure and peripheral vascular disease. Preventing vascular events is the primary goal of therapy. Optimal cardiac care for the patient with diabetes should focus on aggressive management of traditional CV risk factors to optimize blood glucose, lipid and blood pressure control. Targeting medical therapy to improve plaque stability and diminish platelet hyper-responsiveness reduces the frequency of events associated with atherosclerotic plaque burden. In patients with critical lesions, revascularization strategies, either percutaneous or surgical, will often be necessary to improve symptoms and prevent vascular events. Improved understanding of the vascular biology will be crucial for the development of new therapeutic agents to prevent CV events and improve outcomes in patients with diabetes. [source]


    Salient virulence factors in anaerobic bacteria, with emphasis on their importance in endodontic infections

    ENDODONTIC TOPICS, Issue 1 2004
    Ingar Olsen
    Endodontic infections by microbial invasion of the necrotic pulp lead to apical periodontitis of both acute and chronic forms. Acute lesions often develop from multiplication of bacteria in primary infections. Such lesions may also occur as exacerbations of chronic forms provoked for example in conjunction with endodontic treatment measures. The clinical course appears related to the character of the microflora. While primary infections are predominated by a mixed flora of anaerobic bacteria and resembles that of aggressive marginal periodontitis, chronic forms of apical periodontitis emerge following regression of the acute infection, whereupon prevailing bacteria have assumed low activity. The significance of virulence factors is easy to understand as far as acute inflammatory conditions are concerned. The role of virulence factors for sustaining chronic inflammation is more unclear and complex. This review is about salient virulence factors in some selected bacterial genera such as Peptostreptococcus, Porphyromonas, Prevotella and Fusobacterium, which often predominate the root canal microbiota in the acute phase of endodontic infections.

    Elevated sweat sodium associated with pulmonary oedema in meningococcal sepsis

    EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 8 2004
    M. Eisenhut
    Abstract Background, We observed a temporary positive sweat test with sodium and chloride levels greater than 60 mmol L,1 following meningococcal septicaemia. Objective was to investigate whether this finding is reproducible and whether this disturbance in epithelial sodium transport is related to sepsis-induced pulmonary oedema. Materials and methods, Twenty-four children with a diagnosis of meningococcal septicaemia and 10 controls with noninfectious critical illness admitted to the Royal Liverpool Children's Hospital were included. Sweat collection was by pilocarpine iontophoresis in the acute phase of the illness (days 1,5) and on follow up. Sodium and chloride concentrations were determined by flame photometry. Results, In patients with meningococcal septicaemia, sweat sodium and chloride concentrations were significantly higher in the acute compared with the recovery phase, with a mean (SD) of 31·0 (14·6) mmol L,1 in the acute vs. 19·6 (10·2) mmol L,1 on recovery for sodium and 21·0 (12·1) mmol L,1 in the acute vs. 11·8 (4·9) mmol L,1 on recovery for chloride (P < 0·01, t -test, for sodium and chloride). Sweat sodium and chloride were significantly higher in patients with meningococcal disease compared with controls and in the acute phase in patients with septicaemia-related pulmonary oedema [mean (SD) sodium: 41·0 (15·4) mmol L,1 and chloride: 28·8 (14·3) mmol L,1] compared with septic patients without [mean (SD) sodium: 24·5 (10·1) mmol L,1 and chloride: 15·3 (7·9) mmol L,1] (P < 0·01 for sodium and chloride). Conclusions, This is the first study to provide in vivo evidence of reduced epithelial sodium transport in children with septicaemia and of its association with pulmonary oedema. [source]


    Changes of gallbladder and gastric dynamics in patients with acute hepatitis A

    EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 7 2001
    P. Portincasa
    Transient alterations of gallbladder morphology and dynamics have been reported in patients with during acute hepatitis A. The presence of dyspepsia also suggests involvement of gastric motility. During a 60-day follow-up, we investigated gallbladder and gastric motility in relation to dyspepsia in acute viral hepatitis A patients. Twenty patients were assessed at referral (day 0) and at days 7, 21, 42 and 60 and compared with 20 healthy volunteers. Gallbladder morphology and motility and gastric motility were assessed in the fasting and postprandial period by functional ultrasonography using a liquid test meal. Dyspeptic symptoms were scored. At day 0, fasting gallbladder volume was 5·9 ± 1·3 mL, 32·6 ± 4·6 mL, and 21·5 ± 1·9 mL (mean ±,SE) in patients with gallbladder sludge (n = 7), without sludge (n = 13) and controls, respectively (P < 0·05 in sludge vs. no sludge and controls; P < 0·05 in no sludge vs. controls, anova). Small fasting gallbladder volume in patients with sludge increased and sludge disappeared within 7 days. At day 0, patients with sludge also had increased thickness of fasting gallbladder wall and increased serum transaminase levels compared with patients without sludge and controls. Gallbladder contraction was similar in patients and controls. However, patients had delayed gastric emptying, which positively correlated with dyspepsia score. Gallbladder morphological changes observed in the acute phase of hepatitis A are transient and are associated with hepatocellular damage. Gastric emptying is delayed during the first week of disease and is associated with dyspeptic symptoms. [source]


    Trypanosoma cruzi infection modulates intrathymic contents of extracellular matrix ligands and receptors and alters thymocyte migration

    EUROPEAN JOURNAL OF IMMUNOLOGY, Issue 9 2003
    Vinícius Cotta-de-Almeida
    Abstract Several T cell abnormalities have been described in the course of acute Trypanosoma cruzi infection in mice, including severe effects on the thymus. In the present study, looking at the expression of extracellular matrix ligands in the thymus, we observed that deposits of fibronectin and laminin increased progressively during the course of infection, reaching a maximum at the peak of parasitemia and thymic atrophy. Concomitantly, membrane expression of fibronectin and laminin receptors (VLA-4, VLA-5 and VLA-6) was also enhanced on thymocyte subsets of infected mice. These results correlated with changes in intrathymic thymocyte migration ability during the acute phase of infection, when a higher fibronectin-dependent transmigratory activity of CD4+CD8+ thymocytes was observed. Strikingly, we detected higher frequency of immature and high VLA-expressing CD4+CD8+ T cells in the peripheral lymphoid organs of infected mice at thepeak of parasitemia. These cells seemed to be thymus dependent, since significantly lower amounts of them were found in thymectomized mice, and some of them carry "prohibited" V, segments of the TCR. Our data suggest an imbalance in the intrathymic cell trafficking following acute T. cruzi infection, likely due to dysregulated extracellular matrix-dependent interactions. [source]


    EFNS guideline on the treatment of cerebral venous and sinus thrombosis

    EUROPEAN JOURNAL OF NEUROLOGY, Issue 6 2006
    K. Einhäupl
    Cerebral venous and sinus thrombosis (CVST) is a rather rare disease which accounts for <1% of all strokes. Diagnosis is still frequently overlooked or delayed due to the wide spectrum of clinical symptoms and the often subacute or lingering onset. Current therapeutic measures which are used in clinical practice include the use of anticoagulants such as dose-adjusted intravenous heparin or body weight-adjusted subcutaneous low-molecular-weight heparin (LMWH), the use of thrombolysis, and symptomatic therapy including control of seizures and elevated intracranial pressure. We searched MEDLINE (National Library of Medicine), the Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Library to review the strength of evidence to support these interventions and the preparation of recommendations on the therapy of CVST based on the best available evidence. Review articles and book chapters were also included. Recommendations were reached by consensus. Where there was a lack of evidence, but consensus was clear we stated our opinion as good practice points. Patients with CVST without contraindications for anticoagulation should be treated either with body weight-adjusted subcutaneous LMWH or dose-adjusted intravenous heparin (good practice point). Concomitant intracranial haemorrhage related to CVST is not a contraindication for heparin therapy. The optimal duration of oral anticoagulation after the acute phase is unclear. Oral anticoagulation may be given for 3 months if CVST was secondary to a transient risk factor, for 6,12 months in patients with idiopathic CVST and in those with ,mild' hereditary thrombophilia. Indefinite anticoagulation (AC) should be considered in patients with two or more episodes of CVST and in those with one episode of CVST and ,severe' hereditary thrombophilia (good practice point). There is insufficient evidence to support the use of either systemic or local thrombolysis in patients with CVST. If patients deteriorate despite adequate anticoagulation and other causes of deterioration have been ruled out, thrombolysis may be a therapeutic option in selected cases, possibly in those without intracranial haemorrhage (good practice point). There are no controlled data about the risks and benefits of certain therapeutic measures to reduce an elevated intracranial pressure (with brain displacement) in patients with severe CVST. Antioedema treatment (including hyperventilation, osmotic diuretics and craniectomy) should be used as life saving interventions (good practice point). [source]


    The study of cell-mediated immune response in recurrent vulvovaginal candidiasis

    FEMS IMMUNOLOGY & MEDICAL MICROBIOLOGY, Issue 2 2000
    U. Nawrot
    Abstract The aim of this work was to examine in vitro the ability of cells from patients with recurrent vulvovaginal candidiasis (RVVC) to cell-mediated immune response. Peripheral blood mononuclear cells (PBMC) and whole blood cells (WBC) of 37 RVVC patients in acute infection and 14 in remission were examined for the ability to proliferation and cytokines production (IFN, TNF, IL-6). As a control, a group of 25 healthy women were examined. The cells were stimulated with Candida antigen (HKCA), LPS and PHA. To indicate the level of cytokines, the following cell-lines were used: A549 for IFN, WEHI 164 for TNF and 7TD1 for IL-6. The proliferation/death of cells was determined by colorimetric test using MTT. Distinct suppression of cell-mediated immune response (CMI) was shown in all patients comparing to the control. Greatest suppression was found in the acute phase of the disease. The ability of cells to proliferate and produce IFN increases only in remission. The data seem to suggest that in this phase of disease, the ability of cell-mediated immune response is restored. It was also indicated that IFN may take part in protection against Candida infection.

    Increased serum anandamide level at ruptured plaque site in patients with acute myocardial infarction

    FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 3 2009
    Naotaka Maeda
    Abstract Inflammation caused by activated macrophages and T lymphocytes may trigger plaque rapture in acute coronary syndrome (ACS). Anandamide and 2-arachidonylglycerol (2-AG) are macrophage-derived signal lipids and may be involved in the pathogenesis of ACS, but no clinical relevant data have been reported. In 43 acute myocardial infarction (AMI) patients (66 ± 2 years), blood samples were obtained from the aortic root and the infarct-related coronary artery (IRA) using a PercuSurge system during primary percutaneous coronary intervention (PCI). In six patients with stable effort angina (SEA) (56 ± 6 years), blood samples were obtained from the site of stenosis during elective PCI. In 25 of the 43 AMI patients, anandamide was detected in the serum. Serum anandamide level was 35 ± 20 pmol/mL in the aorta and was significantly increased to 401 ± 134 pmol/mL in the IRA (P < 0.01). 2-AG was undetectable in most of the patients. In patients with SEA, neither anandamide nor 2-AG was detected in the serum at the plaque site. In AMI patients with anandamide detected, left ventricular ejection fraction at 2 weeks after PCI was increased by 3.7 ± 2.1% compared with that at the acute phase, while it was decreased by 3.0 ± 1.8% in those without anandamide detected (P < 0.05). The serum anandamide level at the culprit lesion was elevated compared with the systemic level in a significant number of AMI patients, indicating the synthesis of anandamide at the IRA. Anandamide was suggested to be derived from ruptured plaque and may exert beneficial effects in humans. [source]


    Diabetes hyperglycemia and recovery from stroke

    GERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 1-2 2001
    Christopher S Gray
    Strokeis a major cause of death and severe disability in older people. Despite the burden of disease, there is still no safe, simple and proven medical therapy for the treatment of acute stroke. Advances in acute stroke treatment have been either consistently disappointing (neuroprotective therapy) or fraught with controversy regarding risk/benefit (thrombolysis), and attention is once again being directed towards physiological variables that may influence outcome. Both insulin-dependent and non-insulin-dependent diabetes mellitus are major risk factors for stroke. Diabetes mellitus has also been shown to be associated with increased mortality and reduced functional outcome after stroke. Hyperglycemia is a frequent finding following stroke and may reflect the metabolic stress of the acute event, so-called stress hyperglycemia, and/or underlying impaired glucose metabolism. Several large clinical studies have now demonstrated a positive association between a raised blood glucose and poor outcome from stroke; greater mortality and reduced functional recovery. What is not clear is to what extent hyperglycemia is a ,normal' physiological response to stroke or whether hyperglycemia per se increases cerebral damage in the acute phase. There are many potential mechanisms by which hyperglycemia can exert a harmful effect upon cerebral tissue and it is probable that an important relationship exists, not only between glucose and stroke outcome, but also between insulin and neuroprotection. It remains to be determined whether lowering and maintaining ,normal' glucose levels in the immediate aftermath of stroke, combined with the administration of insulin as an acute treatment, can modify this outcome.

    Therapy of acute hepatitis C

    HEPATOLOGY, Issue S1 2002
    Professor Alfredo Alberti M.D.
    Acute hepatitis C has a high propensity to become chronic, which provides the rationale for treating patients with acute disease attempting to prevent chronicity. Almost all published studies on therapy of acute hepatitis C have been small in size, uncontrolled, and highly heterogeneous as to patient features, dose and duration of treatment, follow-up evaluation, and criteria used to define efficacy and safety. The published studies on treatment of acute hepatitis C have used standard alfa or beta interferon monotherapy: none have evaluated combination therapy of interferon and ribavirin or peginterferon. Several meta-analyses of published studies have concluded that initiation of interferon monotherapy during the acute phase of hepatitis C virus (HCV) infection significantly reduces (by 30% to 40%) evolution to chronic hepatitis. The tolerability of interferon in acute hepatitis C has been excellent, even in symptomatic and icteric patients; the side effects and adverse events being similar in type and frequency to those seen when treating chronic cases. Thus, currently available data support treatment of patients with acute hepatitis C, but data are insufficient to draw firm conclusions about which patients to treat, when therapy should be started, or what regimen is optimal. Future studies of adequate size and design should focus on efficacy and tolerability of peginterferons and whether therapy should be started immediately after diagnosis or delayed for 2 to 4 months to avoid treatment of patients who spontaneously recover.

    An open study of risperidone liquid in the acute phase of schizophrenia

    HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 4 2005
    Reiji Yoshimura
    Abstract An open-label study was performed to investigate the clinical efficacy and mechanisms of risperidone liquid in ameliorating positive symptoms in the acute phase of schizophrenia. Eighty-eight patients (M/F: 50/38; age: 18,74 years;, mean±SD =32±16 years) meeting DSM-IV criteria for schizophrenia and treated with risperidone liquid (14 patients also used lorazepam) were evaluated with regard to their clinical improvement and extrapyramidal side effects using the positive and negative syndrome scale (PANSS) and the Simpson and Angus scale (SAS), while plasma concentrations of HVA and MHPG were analysed by HPLC-ECD before and 4 weeks after risperidone liquid administration. Patients showing a 50% or greater improvement in PANSS scores were defined as responders. An improvement in the PANSS scores related to excitement, hostility and poor impulse control was seen within 7 days after administration of risperidone liquid, and an improvement with regard to hallucinatory behaviour and uncooperativeness was seen within 14 days after its administration. Finally, 68% of patients were classified as responders 4 weeks after risperidone liquid administration. The scores of SAS were not changed after risperidone liquid administration. Pretreatment plasma homovanillic acid (HVA) levels in the responders (8.1±2.9,ng/ml) were higher than those in nonresponders (5.9±1.9,ng/ml). In addition, a negative correlation was seen between the changes in plasma HVA levels and the percentage of improvement in PANSS scores. On the other hand, there were no differences between pretreatment plasma 3-methoxy-4-hydroxyphenylglycol (MHPG) levels and those of nonresponders. These results suggest that risperidone liquid is effective and well tolerated for the treatment of acute phase schizophrenic patients, and that efficacy is related to its affects on dopaminergic activity, not noradrenergic activity.

    Establishment and recall of CD8+ T-cell memory in a model of localized transient infection

    IMMUNOLOGICAL REVIEWS, Issue 1 2006
    Katherine Kedzierska
    Summary:, The influenza A virus model of localized, transient respiratory infection provides a well-defined experimental system for dissecting the induction and maintenance of CD8+ T-cell memory. This review focuses on quantitative and qualitative aspects of the prominent DbNP366 - and DbPA224 -specific CD8+ T-cell responses in virus-infected B6 mice. The different virus-specific effector and memory sets are compared by phenotypic [CD62L, interleukin-7 receptor-, (IL-7R,), and IL-15R, expression] and functional [interferon-, (IFN-,), tumor necrosis factor-, (TNF-,), and IL-2 production] analyses. Most clonotypes [defined by T-cell receptor (TCR) CDR3, sequence] generated during the acute phase of infection survive into memory, with those expressing the more consensus ,canonical' TCRs being the major contributors to the recall response. The extent of clonal expansion and the size of memory CD8+ T-cell populations has been characterized for mice challenged with either wildtype or mutant viruses, where broadly equivalent DbNP366 and DbPA224 expression was achieved by disabling the peptides in their native configuration, then expressing them in the viral neuraminidase protein. Combining the clonotypic and antigen dose analyses led to a somewhat mechanistic conclusion that the magnitude of any virus-specific CD8+ T-cell response will be a direct function of antigen dose and the size of the naïve or memory CD8+ T-cell precursor pool.

    The Virtual International Stroke Trials Archive (VISTA): results and impact on future stroke trials and management of stroke patients

    INTERNATIONAL JOURNAL OF STROKE, Issue 2 2010
    C. Weimar
    Background The Virtual International Stroke Trials Archive was established to improve stroke care and trial design through the collation, categorization and potential access to data sets from clinical trials for the treatment of stroke. Methods Virtual International Stroke Trials Archive currently provides access to a combined data set of 29 anonymised acute stroke trials and one acute stroke registry with data on >27 500 patients aged between 18 and 103 (mean 71) years. Results Virtual International Stroke Trials Archive has facilitated research across a broad canvas. The prognosis was poor in patients with very high blood pressure at the time of admission or with a wide variability of systolic blood pressure during the acute phase. The late occurrence of hyperthermia following an ischaemic stroke worsens the prognosis. Stroke lateralisation is not an important predictor of cardiac adverse events or 90-day mortality. Haemorrhagic transformation is seen frequently in patients with cardio-embolic strokes and is associated with a poor prognosis when occurring after the acute phase. Virtual International Stroke Trials Archive has allowed various prognostic models for patients with ischaemic or haemorrhagic stroke to be established and validated. More direct outcomes such as lesion volume can be useful in phase II clinical trials for determining whether a phase III trial should be undertaken. New outcome measures such as ,home time' may also strengthen future trials. On a worldwide level, the prognosis of stroke patients differs considerably between various countries. Conclusion Virtual International Stroke Trials Archive provides an excellent opportunity for analysis of natural history data and prognosis. It has the potential to influence clinical trial design and implementation through exploratory data analyses. [source]


    Physiological monitoring in acute stroke: a literature review

    JOURNAL OF ADVANCED NURSING, Issue 6 2007
    Stephanie P. Jones
    Abstract Title.,Physiological monitoring in acute stroke: a literature review Aim., This paper is a report of a review of the literature that considers how physiological parameters may affect outcome after stroke and the implications of this evidence for monitoring. Background., Throughout the world, the incidence of first-ever stroke is approximately 200 per 100,000 people per year [Sudlow et al. (1997)Stroke28, 491]. Stroke is the third most common cause of mortality [Sarti et al. (2000) Stroke31, 1588] and causes 5·54 million deaths worldwide [Murray & Lopez (1997) Lancet349, 268]. Physiological monitoring is considered a fundamental component of acute stroke care. Currently, the strength of evidence to support its use and identify its components is unclear. Nurse-led physiological assessment and subsequent interventions in acute stroke may have the potential to improve survival and reduce disability. Data sources., Online bibliographic databases from 1966 to 2007, including MEDLINE, EMBASE, CINAHL, AMED, Cochrane and ZETOC, were searched systematically. We identified 475 published papers relating to blood pressure, oxygen saturation and positioning, blood glucose and body temperature. Review methods., Titles and abstracts were reviewed independently by two reviewers and 61 relevant studies were read in full. The quality of included studies was assessed and proformas were used to record detailed data. A narrative synthesis described how the evidence from the papers could inform our understanding of physiological parameters and their association with outcome. Results., Current evidence suggests that patient outcome is worse when physiological parameters deviate from ,normal' in the acute phase of stroke. Conclusions., The evidence supports the need for monitoring and recording of blood pressure, oxygen saturation (including consideration of positioning), blood glucose and body temperature in the acute phase of stroke. This review has reinforced the importance of monitoring physiological parameters in the acute phase of stroke and adds support to the recommendation that monitoring should play a key role within nursing care.

    The Poor Outcome of Ischemic Stroke in Very Old People: A Cohort Study of Its Determinants

    JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 1 2010
    Licia Denti MD
    OBJECTIVES: To assess how much of the excess risk of poor outcome from stroke in people aged 80 and older aging per se explains, independent of other prognostic determinants. DESIGN: Cohort, observational. SETTING: University hospital. PARTICIPANTS: One thousand five hundred fifty-five patients with first-ever ischemic stroke consecutively referred to an in-hospital Clinical Pathway program were studied. MEASUREMENTS: The relationship between age and 1-month outcome (death, disability (modified Rankin Scale 3,5), and poor outcome (modified Rankin Scale 3,6)) was assessed, with adjustment for several prognostic factors. RESULTS: Six hundred twelve patients aged 80 and older showed worse outcome after 1 month than those who were younger, in terms of mortality (19% vs 5%, hazard ratio (HR)=3.85, 95% confidence interval (CI)=2.8,5.4) and disability (51% vs 33%, odds ratio (OR)=3.16, 95% CI=2.5,4.0), although in multivariate models, the adjusted HR for mortality decreased to 1.47 (95% CI=1.0,2.16) and the ORs for disability and poor outcome decreased to 1.76 (95% CI=1.32,2.3.) and 1.83 (95% CI=137,2.43), respectively. Stroke severity, the occurrence of at least one medical complication, and premorbid disability explained most of the risk excess in the oldest-old. CONCLUSION: Stroke outcome is definitely worse in very old people, and most of the excess risk of death and disability is attributable to the higher occurrences of the most-severe clinical stroke syndromes and of medical complications in the acute phase. These represent potential targets for preventive and therapeutical strategies specifically for elderly people. [source]


    Malingering, Perceptions of Illness, and Compensation Seeking in Whiplash Injury: A Comparison of Illness Beliefs Between Individuals in Simulated Compensation Scenarios and Litigation Claimants,

    JOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 11 2006
    Maggie Linnell
    This paper compares beliefs about whiplash injury between individuals in simulated compensation/no compensation scenarios and actual litigant claimants. Comparisons between simulators and the clinical sample revealed that chronic patients reported significantly more symptoms than all simulator groups. The beliefs of the real compensation claimants in the acute phase of the condition were similar to those in the ,injury only' simulator group. The analyses identified a trend towards beliefs in the expected timeline of the illness becoming more negative with time, whilst feelings of control over the symptoms improve. The paper discusses indicators of malingering behavior and the possible involvement of litigation and treatment processes in the transition to a chronic state of ill health. [source]


    High-dose intravenous paraoxon exposure does not cause organophosphate-induced delayed neuropathy (OPIDN) in mini pigs

    JOURNAL OF APPLIED TOXICOLOGY, Issue 4 2001
    G. Petroianu
    Abstract Organophosphorus compounds are inhibitors of serine hydrolases. Some of these compounds produce, in addition to their high acute toxicity, a more persistent effect: organophosphate-induced delayed neuropathy (OPIDN). The putative molecular entity whose inhibition is thought to be responsible for OPIDN is the neuropathy target esterase (NTE). Although in vitro NTE is resistant to paraoxon (PX), occasional case reports have associated PX with OPIDN. To assess clinically whether or not high-dose i.v. PX causes OPIDN in mini pigs, 14 mini pigs were anaesthesized, intubated and mechanically ventilated. In a first set of experiments eight pigs received 1 mg PX kg,1 body weight (BW) dissolved in alcohol. Two control animals received alcohol in a corresponding amount. After infusion of PX, survival of the animals during the acute phase of intoxication was achieved by intensive-care support, using appropriate drugs and fluids according to a pre-established protocol. The mini pigs were extubated 1036 ± 363 min later (mean ± SD). The pigs were observed prior to PX application and for 6 weeks thereafter for any abnormalities and/or signs of OPIDN, such as leg weakness, ataxia and paralysis. Observations were graded on a scale for three categories (position, motor deficiency, reaction), with a maximal cumulative score of 9. In a second set of experiments (four additional pigs) larger PX doses were used (3, 9, 27 and 81 mg kg,1 BW). After recovering from general anaesthesia/surgery, within 2 weeks all animals reached the initial score on the scale. It can be concluded that high-dose i.v. PX exposure does not induce OPIDN in mini pigs during the 6-week observation period. Copyright © 2001 John Wiley & Sons, Ltd. [source]


    Osteopontin as two-sided mediator of intestinal inflammation

    JOURNAL OF CELLULAR AND MOLECULAR MEDICINE, Issue 6 2009
    Katja Heilmann
    Abstract Osteopontin (OPN) is characterized as a major amplifier of Th1-immune responses. However, its role in intestinal inflammation is currently unknown. We found considerably raised OPN levels in blood of wild-type (WT) mice with dextran sodium sulfate (DSS)-induced colitis. To identify the role of this mediator in intestinal inflammation, we analysed experimental colitis in OPN-deficient (OPN,/,) mice. In the acute phase of colitis these mice showed more extensive colonic ulcerations and mucosal destruction than WT mice, which was abrogated by application of soluble OPN. Within the OPN,/, mice, infiltrating macrophages were not activated and showed impaired phagocytosis. Reduced mRNA expression of interleukin (IL)-1 , and matrix metalloproteinases was found in acute colitis of OPN,/, mice. This was associated with decreased blood levels of IL-22, a Th17 cytokine that may mediate epithelial regeneration. However, OPN,/, mice showed increased serum levels of tumour necrosis factor (TNF)-,, which could be due to systemically present lipopolysaccharide translocated to the gut. In contrast to acute colitis, during chronic DSS-colitis, which is driven by a Th1 response of the lamina propria infiltrates, OPN,/, mice were protected from mucosal inflammation and demonstrated lower serum levels of IL-12 than WT mice. Furthermore, neutralization of OPN in WT mice abrogated colitis. Lastly, we demonstrate that in patients with active Crohn's disease OPN serum concentration correlated significantly with disease activity. Taken together, we postulate a dual function of OPN in intestinal inflammation: During acute inflammation OPN seems to activate innate immunity, reduces tissue damage and initiates mucosal repair whereas during chronic inflammation it promotes the Th1 response and strengthens inflammation.

    Use of the eie-recombinant-chagas-biomanguinhos kit to monitor cure of human chagas' disease

    JOURNAL OF CLINICAL LABORATORY ANALYSIS, Issue 3 2002
    Edimilson D. Silva
    Abstract We used the EIE-Recombinant-Chagas-Biomanguinhos kit (EIE-Rec kit) developed by the Oswaldo Cruz Foundation, Brazil, to monitor cure of chagasic patients who were treated during the acute phase of T. cruzi infection. Treated patients were previously studied by parasitological and serological tests and classified as cured patients (CP) (n = 10), dissociated patients (DP) (n = 6), and noncured patients (NCP) (n = 6). When sera of these patients were assayed by EIE-Rec kit all sera from NCP and all sera from CP showed positive and negative reactions, respectively. These results were in full agreement with those obtained previously by the classical tests. Two DP showed a positive reaction; the remaining four displayed a negative reaction, similar to that observed in sera from nonchagasic (NCh) individuals, and could therefore be considered CP. Our results suggest that the EIE-Rec kit could be used to monitor the efficacy of Chagas' disease treatment. J. Clin. Lab. Anal. 16:132,136, 2002. © 2002 Wiley-Liss, Inc. [source]


    Quality of life in chronic disease: a comparison between patients with heart failure and patients with aphasia after stroke

    JOURNAL OF CLINICAL NURSING, Issue 13-14 2010

    Objectives., This study aimed to describe the impact of heart failure and of stroke with aphasia on quality of life (QoL) and to compare the different domains of QoL in these groups. Background., The prevalence of chronic conditions has increased during the last decades, and chronic diseases such as stroke and heart failure may have a great impact on QoL. Design., Comparative study of patients from two randomised controlled studies. Method., Seventy-nine patients with heart failure and 70 patients with aphasia after stroke were evaluated concerning the severity of their disease and by QoL, as measured with the Nottingham Health Profile, in the acute phase and after six months. Results., The severity of the disease improved between baseline and six month for both groups. Correlations between New York Heart Association (NYHA) class and all QoL domains were seen in patients with heart failure after six months. The degree of aphasia correlated to mobility, social, emotional and total score after six month. QoL in patients with heart failure was more affected in the domains of sleep and energy in the acute phase and in the energy domain at six months. Conclusion., Although low energy is more frequent among patients with heart failure, both groups report poor QoL. Improvement in severity of the disease is not necessarily accompanied by improvement in QoL. Relevance to clinical practice., Nottingham Health Profile can easily be used as a screening instrument, aiming to identify patients at risk for adverse effects on QoL. A better understanding of the subjective QoL of patients with chronic disease is fundamental for health care professionals to be able to identify and support vulnerable patients. [source]


    A modified Mini Nutritional Assessment without BMI can effectively assess the nutritional status of neuropsychiatric patients

    Aim and objectives., To determine whether a modified version of the Mini Nutritional Assessment (MNA) without body mass index (BMI) can effectively identify individuals at risk of malnutrition among patients with neuropsychiatric disorders. Background., Neuropsychiatric patients have an additional risk of nutritional disorder due to functional impairments and drug effects. However, their nutritional status is generally neglected. It is important to find a tool that is simple, easy to use and non-invasive. Design., The study involved 105 patients in the acute phase of confirmed neuropsychiatric disorders in an area hospital. All subjects were cognitively able to have effective verbal communication. Method., The study included serum biochemical and anthropometric measurements and an on-site, in-person interview using a structured questionnaire to elicit personal data, health condition and answers to questions in the MNA. Subjects' nutritional statuses were graded with a MNA that adopted population-specific anthropometric cut-off points or one further with the BMI question removed and its assigned score redistributed to other anthropometric questions. Results., Both versions of the modified MNA effectively graded the nutritional status of neuropsychiatric patients and showed good correlations with the major nutritional indicators such as BMI, calf circumference and the length of hospital stay. Conclusions., The MNA can effectively assess the nutritional status of neuropsychiatric patients and enhance timely detection and intervention of their nutritional disorders. A modified MNA without the BMI question can maintain the full functionality of the tool. The version does not require weight and height measurements and thus will enhance the usefulness of the instrument. Relevance to clinical practice., Neuropsychiatric patients are a high-risk group of nutritional disorders. The MNA, especially the one without BMI, has the potential to improve professional efficiency of the primary care workers. [source]


    Rapid assessment of a helpdesk service supporting severe acute respiratory syndrome patients and their relatives

    JOURNAL OF CLINICAL NURSING, Issue 6 2004
    Joanne WY Chung PhD
    Background., To contain severe acute respiratory syndrome, the Hong Kong Hospital Authority set a policy that stipulated there should be no visitors to hospital wards. A helpdesk service was established with the goal of providing immediate emotional and communication support to relatives while severe acute respiratory syndrome patients were isolated during the acute phase of the illness. Aim., This study describes the results of a rapid assessment of the effectiveness of a helpdesk service designed to meet the immediate needs of relatives of severe acute respiratory syndrome patients in Hong Kong. Design., Survey. Method., Eighty-three respondents, representing about 46.3% of relatives (179), attending the helpdesk on the day of the study were recruited. Service evaluation data was collected using a self-administered questionnaire completed by respondents. Results., Nearly 100% of respondents who used the service found the delivery service with on-site counselling useful for alleviating their anxiety. However, about half of these relatives complained of insufficient information regarding the patient's condition and progress. The majority of respondents were satisfied with the service. In describing the most important traits of the service providers, caring and enthusiasm were mentioned most frequently by respondents who stated that they were very satisfied with the service. Conclusion., The results support the value of the service, and demonstrate that the service is effective in meeting relatives' immediate needs. These needs include information, aid in fulfilling their role as caretaker for the patient (delivering prepared soup) and psychological support. The results suggest that facilitation of visitation of patients by relatives via video conferencing and education of the public on the nature and course of severe acute respiratory syndrome to reduce the social stigma of having a potentially life-threatening disease should be introduced in Hong Kong. Relevance to clinical practice., The results highlight important attributes that helpers (nurses) should have in order to alleviate the suffering of severe acute respiratory syndrome patients and their relatives.

    Histopathology of a granulomatous lobular panniculitis in acute Q fever: a case report

    JOURNAL OF CUTANEOUS PATHOLOGY, Issue 8 2010
    R Soulard
    Q fever is a zoonotic infection caused by Coxiella burnetii. Two forms of the disease have been described: an acute form with pneumonia, hepatitis or a flu-like syndrome; and a chronic form in which endocarditis is the most frequent clinical expression. We report a 77 year old male with fever and an erythematous nodule on the right leg. Biopsy revealed a granulomatous lobular panniculitis with some granulomas rimmed by an eosinophilic material, giving a "doughnut" or "fibrin-ring" appearance. Q fever serological studies were positive. Cutaneous signs, among them panniculitis, are probably underestimated during the acute phase of the disease, and recognizing different granulomatous patterns may contribute to the diagnosis.

    A multidisciplinary guideline for the acute phase of stroke: barriers perceived by Dutch neurologists

    JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 2 2004
    Trudy Van Der Weijden PhD MD
    Abstract Rationale, aims and objectives, Guidelines for stroke management should improve quality of care. Dissemination of guidelines, however, does not guarantee guideline adherence. The aim of this paper is to investigate barriers for guideline adherence to bring about suggestions for possible implementation strategies. Method, Questionnaire survey among all Dutch neurologists working on neurology wards in general hospitals during the year 2000 in The Netherlands. Results, The neurologists expressed a high degree of agreement with the diagnostic and preventive recommendations, but expressed doubts with regard to the therapeutic recommendations, especially for the recombinant tissue plasminogen activator therapy. In general, barriers at the organizational and the multidisciplinary team level were most prominent. Conclusions, Active implementation of the guidelines seems necessary. Implementation strategies should be focused on the different sources of barriers: the caregiver, the patient and the organization of care. [source]


    An Enhanced Device for Transluminal Retrieval of Vascular Stents Without Surgical Procedures: Experimental Studies

    JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 3 2010
    MASAYUKI TSUCHIDA M.D.
    Background: Although efforts have been focused on developing endovascular procedures by which intravascular devices such as stents could be effectively deployed, few data exist regarding devices for the nonsurgical retrieval of deployed stents. Therefore, we designed to enable retrieval of deployed stents without a surgical procedure. Methods: The device consisted of four components: ultra-low profile forceps with 2.0 mm in diameter, conducting shaft with 1.8 mm in diameter, control handle by which the forceps is opened or closed, and a covering sheath. This device was designed to advance into the vessel lumen along a 0.014-inch guidewire by over the wire fashion. Results: The forceps could firmly catch nonexpanded as well as expanded tubular-type stents with open cells in an in vitro model that was 4.0 mm in diameter. Then, we used this device in porcine renal arteries with 2.5,5.0 mm in diameter. At first, a fragmented 0.014-inch guidewire could be safely removed without vessel damage that was confirmed by intravascular ultrasound. This device could successfully remove four of five inappropriately and 11 of 14 appropriately deployed stents. Under these conditions, intravascular ultrasound demonstrated minor vessel wall dissection in two-third of cases. Conclusions: These results demonstrate that the present device can be used for transluminal removal of foreign bodies such as nonexpanded as well as expanded stents in acute phase. Further miniaturization may enable using this type of device in the renal as well as coronary arteries. (J Interven Cardiol 2010;23:264,270) [source]


    Timing of Death and Myocardial Infarction in Patients with Non-ST Elevation Acute Coronary Syndromes: Insights From Randomized Clinical Trials

    JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 5 2007
    M.S., RAJENDRA H. MEHTA M.D.
    Background: Adverse events occur following non-ST elevation acute coronary syndromes (NSTE ACS). However, the timing of these events in relation to index event is less clear. Methods: Accordingly, we evaluated 26,466 NSTE ACS patients from the Global Use of Strategies to Open Occluded Arteries in Acute Coronary Syndromes (GUSTO-IIb), Platelet Glycoprotein IIb/IIIa in Unstable Angina: Receptor Suppression Using Integrilin Therapy (PURSUIT), and Platelet IIb/IIIa Antagonism for the Reduction of Acute Coronary Syndrome Events in a Global Organization Network (PARAGON) A and B trials to ascertain the timing of adverse events. Outcomes of interest were death, myocardial infarction (MI), and death or MI at 180 days. Logistic regression modeling for death was used to categorize patients into low-, medium-, and high-risk groups. Results: At 6 months, 6.2% of patients died, 12.1% had MI, and 15.7% suffered death or MI. From 15% to 40% of these events occurred beyond 30 days. At 6 months, 3%, 4%, and 13% of patients died in low-, medium-, and high-risk groups, respectively. However, the proportion of patients dying beyond 30 days was similar in the three groups (44%, 43%, and 41% of death, respectively). Similarly, whereas death or MI increased with higher risk (11%, 14%, and 23%, respectively), the proportion of patients with this event beyond 30 days did not differ in the three strata (22%, 20%, and 25%, respectively). Conclusions: Our study provides important insights into the timing of adverse events and suggests that the substantial proportion of patients suffer subsequent adverse events after their index NSTE ACS. Thus, these data call for continuous surveillance for these events and efforts beyond the acute phase at increasing adherence to evidence-based therapies to improve the outcomes of these patients.
