Illness Severity (illness + severity)
Selected AbstractsObsessive-compulsive disorder among African Americans and blacks of Caribbean descent: results from the national survey of American life,DEPRESSION AND ANXIETY, Issue 12 2008Joseph A. Himle Ph.D. Abstract Background: There is limited research regarding the nature and prevalence of obsessive-compulsive disorder (OCD) among various racial and ethnic subpopulations within the United States, including African Americans and blacks of Caribbean descent. Although heterogeneity within the black population in the United States has largely been ignored, notable differences exist between blacks of Caribbean descent and African Americans with respect to ethnicity, national heritage, and living circumstances. This is the first comprehensive examination of OCD among African Americans and blacks of Caribbean descent. Methods: Data from the National Survey of American Life, a national household probability sample of African Americans and Caribbean blacks in the United States, were used to examine rates of OCD among these groups. Results: Lifetime and 12-month OCD prevalence estimates were very similar for African Americans and Caribbean blacks. Persistence of OCD and rates of co-occurring psychiatric disorders were very high and also similar between African American and Caribbean black respondents. Both groups had high levels of overall mental illness severity and functional impairment. Use of services was low for both groups, particularly in specialty mental health settings. Use of anti-obsessional medications was also rare, especially among the Caribbean black OCD population. Conclusions: OCD among African Americans and Caribbean blacks is very persistent, often accompanied by other psychiatric disorders, and is associated with high overall mental illness severity and functional impairment. It is also likely that very few blacks in the United States with OCD are receiving evidence-based treatment and thus considerable effort is needed to bring treatment to these groups.

[source] A register study of the impact of stopping third trimester selective serotonin reuptake inhibitor exposure on neonatal healthACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2010W. Warburton Warburton W, Hertzman C, Oberlander TF. A register study of the impact of stopping third trimester selective serotonin reuptake inhibitor exposure on neonatal health. Objective:, To determine whether risk for adverse neonatal outcomes are reduced by stopping SSRI use before the end of pregnancy. Method:, Using population health data, maternal health and prenatal SSRI prescriptions were linked to neonatal birth records (N = 119 547) (1998,2001). Neonates SSRI-exposed in the last 14 days (L14) of gestation were compared with infants who had gestational exposure, but not during the last 14 days (NL14). Propensity score matching was used to control for potential confounders (total exposure, maternal health characteristics). Results:, Increased risk for neonatal respiratory distress was present where L14 exposure occurred compared with risk where exposure stopped before L14. However, controlling for potential maternal and neonatal confounders, differences disappeared. Conclusion:, Controlling for maternal illness severity, reducing exposure to SSRI's at the end of pregnancy had no significant clinical effect on improving neonatal health. These findings raise the possibility that some adverse neonatal outcomes may not be an acute pharmacological condition such as toxicity or withdrawal. [source] Staging anorexia nervosa: conceptualizing illness severityEARLY INTERVENTION IN PSYCHIATRY, Issue 1 2008Sarah Maguire Abstract In recent years, there has been increasing attention to the conceptualization of anorexia nervosa (AN) and its diagnostic criteria. While varying levels of severity within the illness category of AN have long been appreciated, neither a precise definition of severity nor an empirical examination of severity in AN has been undertaken. The aim of this article is to review the current state of knowledge on illness severity and to propose a theoretical model for the definition and conceptualization of severity in AN. AN is associated with significant medical morbidity which is related to the ,severity' of presentation on such markers as body mass index, eating and purging behaviours. The development of a functional staging system, based on symptom severity, is indicated for reasons similar to those cited by the cancer lobby. Improving case management and making appropriate treatment recommendations have been the primary purpose of staging in other fields, and might also apply to AN. Such a standardized staging system could potentially ease communication between treatment settings, and increase the specificity and comparability of research findings in the field of AN. [source] Impact of Critical Bed Status on Emergency Department Patient Flow and OvercrowdingACADEMIC EMERGENCY MEDICINE, Issue 4 2003Stephen Liu MD Objective: To compare measurements of emergency department (ED) patient flow during periods of acute ED overcrowding and times of normal patient volume (NPV). Methods: Retrospective ED chart review comparing ED flow for patients treated in a tertiary care teaching hospital during periods of ED overcrowding, defined as critical bed status (CBS), and NPV. All periods of CBS during July 2001 were identified. CBS time intervals were matched with NPV times by month, day of the week, time of day, and number of care providers. All patients registered during these matched time intervals were reviewed. Times were collected for each of the following activities: check-in, bed placement, physician assessment, first intervention, and disposition. Corresponding intervals were calculated in minutes. Triage category was used as a marker of illness severity (1 = most severe, 5 = least severe). Descriptive statistics were performed. Results: One hundred eighteen patient charts were reviewed: 61 CBS and 57 NPV. There was no statistical difference in illness severity between the two groups. In the cumulative analysis, patients waited significantly longer for an ED bed (30.4 min, p = 0.01) but did not experience significant delays in other intervals. Triage category analysis revealed no significant difference in triage 2 patients. Intermediate-severity patients (triage 3) waited longer in every interval and significantly longer for physician assessment (30.8 min longer, p < 0.05). Low-severity patients (triage 4) waited longer for an ED bed (40 min, p = 0.02) but did not experience other significant delays. Conclusions: During times of acute overcrowding, the most significant delay occurs awaiting placement in the ED bed. [source] Heart Rate Variability in Emergency Department Patients with SepsisACADEMIC EMERGENCY MEDICINE, Issue 7 2002Douglas Barnaby MD Abstract Objective: To test the hypothesis that heart rate variability (HRV) can provide an early indication of illness severity among patients presenting to the emergency department (ED) with sepsis. Methods: The authors enrolled a convenience sample of 15 ED patients meeting the American College of Chest Physicians/Society of Critical Care Medicine criteria for sepsis. Each patient had continuous Holter monitoring performed in the ED. Acute Physiology and Chronic Health II (APACHE II) and Sequential Organ Failure (SOFA) scores were calculated for the day of presentation. Holter tapes obtained in the ED were analyzed off-line to calculate HRV variables for the 5-minute segment with the least artifact and non-sinus beats. These variables were correlated with APACHE II and SOFA scores. Results: LFnu (normalized low-frequency power), an assessment of the relative sympathetic contribution to overall HRV, was correlated with increased illness severity as calculated using APACHE II (r = -0.67, r2= 0.43) and SOFA (r = -0.80, r2= 0.64) scores. LF/HF ratio (low-frequency/high-frequency ratio), a measure of sympathovagal balance, was correlated with the SOFA score [r = -0.54 (95% CI = -0.83 to -0.01), r2= 0.29]. All five patients who required critical care monitoring or ventilatory support or who died during the first 5 days of their hospitalization had LFnu values below 0.5 and LF/HF ratios less than 1.0. None of the patients with measurements greater than these threshold values died or required these interventions during the five days following admission. Conclusions: A single variable, LFnu, which reflects sympathetic modulation of heart rate, accounted for 40-60% of the variance in illness severity scores among patients presenting to the ED with sepsis. HRV, as reflected in LFnu and the LF/HF ratio and measured with a single brief (5-minute) period of monitoring while in the ED, may provide the emergency physician with a readily available, noninvasive, early marker of illness severity. The threshold effect of LFnu and LF/HF in the prediction of early clinical deterioration was an unexpected finding and should be regarded as hypothesis-generating, pending further study. [source] A Dyadic Examination of Daily Health Symptoms and Emotional Well-Being in Late-Life Couples,FAMILY RELATIONS, Issue 5 2006Jeremy B. Yorgason Abstract: This study investigated the link between daily health symptoms and spousal emotional well-being in a sample of 96 older dyads. Higher negative mood and lower positive mood were associated with spousal symptoms in couples wherein husbands or wives reported higher average levels of symptoms. For wives, partner effects were moderated by husbands' marital satisfaction and illness severity. Specifically, higher husband marital satisfaction and illness severity were associated with higher negative mood and lower positive mood for wives on days where husbands reported higher symptom levels. In their work with later-life families, practitioners and educators should address long-term and daily health-related relationship stressors. [source] Complement Activation in Emergency Department Patients With Severe SepsisACADEMIC EMERGENCY MEDICINE, Issue 4 2010John G. Younger Abstract Objectives:, This study assessed the extent and mechanism of complement activation in community-acquired sepsis at presentation to the emergency department (ED) and following 24 hours of quantitative resuscitation. Methods:, A prospective pilot study of patients with severe sepsis and healthy controls was conducted among individuals presenting to a tertiary care ED. Resuscitation, including antibiotics and therapies to normalize central venous and mean arterial pressure (MAP) and central venous oxygenation, was performed on all patients. Serum levels of Factor Bb (alternative pathway), C4d (classical and mannose-binding lectin [MBL] pathway), C3, C3a, and C5a were determined at presentation and 24 hours later among patients. Results:, Twenty patients and 10 healthy volunteer controls were enrolled. Compared to volunteers, all proteins measured were abnormally higher among septic patients (C4d 3.5-fold; Factor Bb 6.1-fold; C3 0.8-fold; C3a 11.6-fold; C5a 1.8-fold). Elevations in C5a were most strongly correlated with alternative pathway activation. Surprisingly, a slight but significant inverse relationship between illness severity (by sequential organ failure assessment [SOFA] score) and C5a levels at presentation was noted. Twenty-four hours of structured resuscitation did not, on average, affect any of the mediators studied. Conclusions:, Patients with community-acquired sepsis have extensive complement activation, particularly of the alternative pathway, at the time of presentation that was not significantly reversed by 24 hours of aggressive resuscitation.

Glickman MD Abstract Background:, Aggressive diagnosis and treatment of patients presenting to the emergency department (ED) with septic shock has been shown to reduce mortality. To enhance the ability to intervene in patients with lesser illness severity, a better understanding of the natural history of the early progression from simple infection to more severe illness is needed. Objectives:, The objectives were to 1) describe the clinical presentation of ED sepsis, including types of infection and causative microorganisms, and 2) determine the incidence, patient characteristics, and mortality associated with early progression to septic shock among ED patients with infection. Methods:, This was a multicenter study of adult ED patients with sepsis but no evidence of shock. Multivariable logistic regression was used to identify patient factors for early progression to shock and its association with 30-day mortality. Results:, Of 472 patients not in shock at ED presentation (systolic blood pressure > 90 mm Hg and lactate < 4 mmol/L), 84 (17.8%) progressed to shock within 72 hours. Independent factors associated with early progression to shock included older age, female sex, hyperthermia, anemia, comorbid lung disease, and vascular access device infection. Early progression to shock (vs. no progression) was associated with higher 30-day mortality (13.1% vs. 3.1%, odds ratio [OR] = 4.72, 95% confidence interval [CI] = 2.01 to 11.1; p , 0.001). Among 379 patients with uncomplicated sepsis (i.e., no evidence of shock or any end-organ dysfunction), 86 (22.7%) progressed to severe sepsis or shock within 72 hours of hospital admission. Conclusions:, A significant portion of ED patients with less severe sepsis progress to severe sepsis or shock within 72 hours. Additional diagnostic approaches are needed to risk stratify and more effectively treat ED patients with sepsis.

Five UK case studies of ,whole systems' of IC were used, with data collected on a sample of consecutive IC episodes between January 2003 and January 2004. Statistical differences in costs and outcomes associated with different IC services and patient groups were explored. Factors associated with variation in IC episode outcomes (EuroQol EQ-5D and Barthel Index) were explored using an econometric framework. Data were available for 2253 episodes of IC. In terms of Department of Health criteria, a large proportion of patients (up to 47% of those for whom data were available) in this study were inappropriately admitted to IC services. As regards service function, compared to supported discharge, admission avoidance services were associated with both lower costs and greater health and functional gains. These gains appear to be driven, in part, by illness severity (more dependent patients tended to gain most benefit). In addition, these gains appear to be larger where the admission was appropriate. Our work suggests a need for the development and application of robust and reliable clinical criteria for admission to IC, and close co-operation between hospital and community service providers over selection of patients and targeting of IC and acute care services to meet defined clinical need. [source] Valuing avoided morbidity using meta-regression analysis: what can health status measures and QALYs tell us about WTP?HEALTH ECONOMICS, Issue 8 2006George Van Houtven Abstract Many economists argue that willingness-to-pay (WTP) measures are most appropriate for assessing the welfare effects of health changes. Nevertheless, the health evaluation literature is still dominated by studies estimating nonmonetary health status measures (HSMs), which are often used to assess changes in quality-adjusted life years (QALYs). Using meta-regression analysis, this paper combines results from both WTP and HSM studies applied to acute morbidity, and it tests whether a systematic relationship exists between HSM and WTP estimates. We analyze over 230 WTP estimates from 17 different studies and find evidence that QALY-based estimates of illness severity , as measured by the Quality of Well-Being (QWB) Scale , are significant factors in explaining variation in WTP, as are changes in the duration of illness and the average income and age of the study populations. In addition, we test and reject the assumption of a constant WTP per QALY gain. We also demonstrate how the estimated meta-regression equations can serve as benefit transfer functions for policy analysis. By specifying the change in duration and severity of the acute illness and the characteristics of the affected population, we apply the regression functions to predict average WTP per case avoided.

[source] Should amenorrhea be a diagnostic criterion for anorexia nervosa?INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 7 2009Evelyn Attia MD Abstract Objective: The removal of the amenorrhea criterion for anorexia nervosa (AN) is being considered for the fifth edition of The Diagnostic and Statistical Manual (DSM-V). This article presents and discusses the arguments for maintaining as well as those for removing the criterion. Method: The psychological and biological literatures on the utility of amenorrhea as a distinguishing diagnostic criterion for AN and as an indicator of illness severity are reviewed. Results: The findings suggest that the majority of differences among patients with AN who do and do not meet the amenorrhea criterion appear largely to reflect nutritional status. Overall, the two groups have few psychological differences. There are mixed findings regarding biological differences between those with AN who do and do not menstruate and the relationship between amenorrhea and bone health among patients with AN. Discussion: Based on these findings, one option is to describe amenorrhea in DSM-V as a frequent occurrence among individuals with AN that may provide important information about clinical severity, but should not be maintained as a core diagnostic feature. The possibilities of retaining the criterion or eliminating it altogether are discussed. © 2009 American Psychiatric Association.

Methods We interviewed 224 people with Alzheimer's disease (AD) and their carers, recruited to be representative in terms of their severity, sex and living situation as part of the LASER-AD study; and determined whether they entered 24-h care in the subsequent 4.5,years. We tested a comprehensive range of characteristics derived from a systematic review, and used Cox proportional hazard regression to determine whether they independently predicted entering 24-h care. Results The main independent predictors of shorter time to enter 24-h care were the patient being: more cognitively or functionally impaired (hazard ratio (HR),=,1.09; 95% CI,=,1.06,1.12) and (HR,=,1.04 95% CI,=,1.03,1.05), having a paid versus a family carer (HR,=,2.22; 95% CI,=,1.39,3.57), the carer being less educated (HR,=,1.43; 95% CI,=,1.12,1.83) and spending less hours caring (HR,=,1.01; 95% CI,=,1.00,1.01). Conclusion As having a family carer who spent more time caring (taking into account illness severity) delayed entry to 24-h care, future research should investigate how to enable carers to provide this. Other interventions to improve patients' impairment may not only have benefits for patients' health but also allow them to remain longer at home. This financial benefit could more than offset the treatment cost. Copyright © 2009 John Wiley & Sons, Ltd. [source] Long-term effect of the ICU-diary concept on quality of life after critical illnessACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010C. G. BÄCKMAN Background: Critically ill patients often spend time in the intensive care unit (ICU) either unconscious or sedated. On recovery, they are often in a state of confusion with memory loss that may be associated with a longstanding reduction in health-related quality of life (QoL). We hypothesised that the ICU-diary concept could improve their QoL by filling in their memory gaps. Methods: A non-randomised, prospective study in a non-academic eight-bedded general ICU. A group of patients (n=38) were selected to receive the ICU-diary concept (keeping a diary with photos while on the ICU plus a follow-up meeting) when a long and complicated course was expected. Health-related QoL at 6, 12, 24 and 36 months was compared with a group that did not receive the ICU-diary (n=224). The Medical Outcomes Study 36-Item Short-Form (SF-36) was used to measure health-related QoL. Multiple regression models adjusted for age, sex, illness severity, pre-existing disease and diagnostic category was used to analyse the effects of the ICU-diary concept at 6 months, and changes over time were analysed using repeated measures MANOVA. Results: Crude and adjusted scores for two dimensions of SF-36 (general health and vitality) and the physical component summary score were significantly higher at 6 months in the ICU-diary group (P<0.05) and some of the effects remained during the 3-year follow-up period (P<0.05). Conclusion: The ICU-diary concept was associated with improved health-related QoL during the 3-year follow-up period after a critical illness. The effect of this intervention needs to be confirmed in a larger randomised study. [source] Cardiovascular Exercise Training Extends Influenza Vaccine Seroprotection in Sedentary Older Adults: The Immune Function Intervention TrialJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 12 2009Jeffrey A. Woods PhD OBJECTIVES: To determine whether cardiovascular exercise training resulted in improved antibody responses to influenza vaccination in sedentary elderly people who exhibited poor vaccine responses. DESIGN: Single-site randomized parallel-arm 10-month controlled trial. SETTING: University of Illinois at Urbana-Champaign. PARTICIPANTS: One hundred forty-four sedentary, healthy older (69.9 ± 0.4) adults. INTERVENTIONS: Moderate (60,70% maximal oxygen uptake) cardiovascular exercise was compared with flexibility and balance training. MEASUREMENTS: The primary outcome was influenza vaccine response, as measured according to hemagglutination inhibition (HI) anti-influenza antibody titer and seroprotective responses (HI titer ,40). Secondary measures included cardiovascular fitness and body composition. RESULTS: Of the 160 participants enrolled, 144 (90%) completed the 10-month intervention with excellent compliance (,83%). Cardiovascular, but not flexibility, exercise intervention resulted in improvements in indices of cardiovascular fitness, including maximal oxygen uptake. Although not affecting peak (e.g., 3 and 6 weeks) postvaccine anti-influenza HI titers, cardiovascular exercise resulted in a significant increase in seroprotection 24 weeks after vaccination (30,100% dependent on vaccine variant), whereas flexibility training did not. CONCLUSION: Participants randomized to cardiovascular exercise experienced improvements in influenza seroprotection throughout the entire influenza season, whereas those in the balance and flexibility intervention did not. Although there were no differences in reported respiratory tract infections, the exercise group exhibited reduced overall illness severity and sleep disturbance. These data support the hypothesis that regular endurance exercise improves influenza vaccine responses. [source] Geriatric Patients Improve as Much as Younger Patients from Hospitalization on General Psychiatric UnitsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 10 2004Mark B. Snowden MD Objectives: To determine whether geriatric patients aged 65 and older on general adult psychiatric units improve as much as younger patients, over what duration their improvement occurs, and their risk of readmission. Design: Cohort study. Setting: Inpatient psychiatric unit of an urban, university-affiliated, county hospital from January 1993 through August 1999. Participants: A total of 5,929 inpatients. Measurements: Standardized, routine assessments by attending psychiatrists included the Psychiatric Symptom Assessment Scale (PSAS) on admission and discharge. Discharge scores, length of stay (LOS), and risk of readmission within 1 year were modeled for the groups using multiple regression analyses. Results: Geriatric patients constituted 5% (n=299) of the 5,929 admissions. In multivariate analysis, geriatric status was not associated with discharge PSAS scores. Median LOS was longer for geriatric patients (16 days) than younger patients (10 days, P<.001), especially in older women (14 days) and geriatric patients with mild medical illness severity (13 days vs 11 days in those with moderate-to-severe medical illness). Geriatric patients were as likely to be readmitted within 1 year of discharge as younger patients. Conclusion: Geriatric patients on general inpatient psychiatry units improved as much as younger patients. Their longer LOS was associated with milder medical illness severity. There may be a role for more specialized care of elderly women or geriatric patients with mild to moderate medical illness to improve the efficiency of their care. [source] Role of gender in depressive disorder outcome for individual and group cognitive,behavioral treatment,JOURNAL OF CLINICAL PSYCHOLOGY, Issue 12 2008Hunna J. Watson Abstract Gender in cognitive,behavioral therapy (CBT) for outcome for depression has been inadequately examined in previous research. Thirty-five men and 55 women diagnosed with a depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV; American Psychiatric Association, 1994) completed individual CBT at an outpatient community mental health clinic and 56 men and 105 women completed group CBT. Depression severity was measured before treatment and at endpoint using the Beck Depression Inventory-II (Beck, Steer, & Brown, 1996) along with secondary outcomes of anxiety (Beck Anxiety Inventory; Beck, Epstein, Brown, & Steer, 1988) and quality of life (Quality of Life Enjoyment and Satisfaction Questionnaire; Endicott, Nee, Harrison, & Blumenthal, 1993). Men and women demonstrated equivalent pretreatment and posttreatment illness severity, a comparable gradient of improvement on outcomes, and attainment of clinically meaningful benchmarks. © 2008 Wiley Periodicals, Inc.

[source] Women, serious mental illness and recidivism: A gender-based analysis of recidivism risk for women with SMI released from prisonJOURNAL OF FORENSIC NURSING, Issue 1 2010Kristin G. Cloyes PhD Abstract Two groups now constitute the fastest growing segment of the U.S. prison population: women and persons with mental illness. Few large-scale studies have explored associations among serious mental illness (SMI), gender, and recidivism, or compared factors such as illness severity and clinical history as these construct notably different situations for incarcerated women and men. We report on our recent study comparing prison recidivism rates, severity of mental illness, and clinical history for women and men released from Utah State Prison 1998,2002. Implications: While women generally have better recidivism outcomes than men, we find that SMI related factors have a greater negative effect on the trajectories of women in this sample as compared with the men. This suggests that programs and policies focused on the SMI-specific risks and needs of women could significantly reduce prison recidivism and increase community tenure for this group, with far-reaching effects for families and communities. [source] Slow-responders to IV ,2 -adrenergic agonist therapy: Defining a novel phenotype in pediatric asthma,PEDIATRIC PULMONOLOGY, Issue 7 2008Christopher L. Carroll MD Abstract Objectives While aerosolized administration of ,2 -adrenergic receptor (,2 -AR) agonists is the mainstay of treatment for pediatric asthma exacerbations, the efficacy of intravenous (IV) delivery is controversial. Failure to demonstrate improved outcomes with IV ,2 -AR agonists may be due to phenotypic differences within this patient population. Our hypothesis is that children who respond more slowly to IV ,2 -AR agonist therapy comprise a distinct phenotype. Methods Retrospective chart review of all children admitted to the ICU for status asthmaticus who were treated with IV terbutaline between December 2002 and September 2006. Results Seventy-eight children were treated with IV terbutaline according to guidelines that adjusted the dose by clinical asthma score. After examining the histogram of duration of terbutaline infusions, a 48-hr cutoff was chosen to define responsiveness. Thirty-eight (49%) children were slow-responders by this definition. There were no significant differences in baseline asthma severity or severity on admission between the slow-responders and responders. Slow-responders required significantly higher total doses of IV terbutaline, higher maximum administration rates, and had longer ICU and hospital length of stay. Conclusion There were significant differences in outcomes between the responders and slow-responders without differences in acute or chronic illness severity. Other factors may have lead to slower response to IV ,2 -agonist therapy. Pediatr Pulmonol. 2008; 43:627,633. © 2008 Wiley-Liss, Inc. [source] Circulating levels of KL-6 in acute respiratory distress syndrome sepsis or traumatic brain injury in critically ill childrenPEDIATRIC PULMONOLOGY, Issue 8 2006George Briassoulis MD Abstract KL-6 is a high molecular weight glycoprotein that is expressed on the apical borders of normal secretary alveolar epithelial cells. The aim of our study was to elucidate the potential role of circulating levels of KL-6, related to C-reacting protein (CRP), disease severity (PRISM, TISS), length of stay (LOS) or mechanical ventilation (LOMV), and outcome, in children with acute respiratory distress syndrome (ARDS), sepsis, or traumatic brain injury (TBI). KL-6 concentrations were monitored using solid phase sandwich enzyme-linked immunosorbent assay in plasma of nine patients with ARDS and compared to nine patients with TBI, nine with sepsis, and nine ventilated patients with cancer of matched illness severity on days 1, 3, 5, 7, and 10. Initial respiratory/ventilatory parameters (oxygenation index, plateau pressures) were recorded for ARDS patients. Patients with ARDS had higher early plasma levels of KL-6 (956,±,400 U/ml), as compared to patients with TBI (169,±,9 U/ml), sepsis (282,±,81 U/ml), and ventilated controls (255,±,40 U/ml). Significant correlations were demonstrated between plasma KL-6 concentration and oxygenation index, PaO2: FiO2 ratio, LOS and LOMV, but not with CRP or PRISM. Only in patients with ARDS, plasma KL-6 levels were higher in non-survivors than survivors (P,<,0.03). Plasma KL-6 levels have possible prognostic significance and may provide a useful marker for ARDS in critically ill children. Pediatr Pulmonol. 2006; 41: 790,795. © 2006 Wiley-Liss, Inc. [source] Clinical scoring systems in cystic fibrosisPEDIATRIC PULMONOLOGY, Issue 7 2006Gaudenz M. Hafen MD Abstract The first cystic fibrosis (CF) scoring system was published in 1958. Since then, many other scoring systems were developed. Clinical parameters, details about statistical evaluations, and recent strategic uses of scores were identified. Several similar scores aiming to assess chronic illness severity (Shwachman-Kulczycki score and a modification, Cooperman, Berneze-score and the NIH score) have not been evaluated and are out of date, given the changing natural history of CF. Of the current scoring systems, the modified Shwachman score by Doershuk is perhaps most reliable for describing follow-up studies. Scores designed for acute changes and short-term evaluation were also developed. The modified Huang score may be useful in the prognostic evaluation of patients with end-stage disease. It could also be used for discrimination of adult patients with differing disease severity and for longitudinal evaluation. Scores assessing pulmonary exacerbations could help provide consensus among clinicians regarding the need for intervention. Most of these scores require further evaluation. Although scores could provide an objective measure of disease severity, progression, need for and response to interventions, including value in selecting patients for lung transplantation and as an outcome measure for research studdies, no scoring system can fulfill all these objectives. Nevertheless, there is a need for the development of a modern day longitudinal score that is sensitive, valid and reproducible, to reflect the milder disease status of patients.

[source] Improvement of cognitive functioning in mood disorder patients with depressive symptomatic recovery during treatment: An exploratory analysisPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 5 2006LAURA MANDELLI Psy. Abstract, Depressive symptoms have a large impact on cognitive test performance of mood disorder patients. After remission, some improvement of cognitive functioning has been observed, but also stable deficits have been reported both during depression and remission. In the present study, the authors aimed to investigate the cognitive functioning of mood disorder patients in relation to early symptomatic recovery, by comparing performances at the Wechsler Adult Intelligence Scale-Revised (WAIS-R) of responders and non-responders to the antidepressant treatment. The sample was composed of 51 hospitalized patients for a major depressive episode (major depressives/bipolars = 37/14). All patients were treated with fluvoxamine and evaluated at baseline and after 4 weeks using the 21-item Hamilton Rating Scale for Depression. All subjects were once assessed for their cognitive functioning with the WAIS-R, at the end of the fourth week of treatment. In the current sample, patients who showed a significant symptomatic remission after 4 weeks of treatment showed higher total WAIS-R scores and a lower incidence of cognitive impairment, compared to non-responders to treatment. No major differences could be observed on any particular subtest, but rather a global improving of scores in responders compared to non-responders to pharmacotherapy. Pre-treatment illness severity, that was significantly higher among non-responders, was significantly associated with patients' intelligence quotient scores. Despite a number of limitations, present data support a strong effect of depressive symptoms on patients WAIS-R performances and an early global improvement of cognitive functioning concurrent with symptomathology recovery during pharmacological treatment. [source] Effects of antenatal magnesium sulfate and corticosteroid therapy on sleep states of preterm infants,RESEARCH IN NURSING & HEALTH, Issue 4 2006Beth Black Abstract This exploratory longitudinal study was designed to compare the neonatal illness severity, sleep,wake, and respiratory sleep behaviors of preterm infants whose mothers received prenatal corticosteroids and/or magnesium sulfate (MgSO4) with those of infants whose mothers did not receive these medications. The 134 infants were divided into four groups: those whose mothers received MgSO4 only, those who received steroids only, those who received both MgSO4 and steroids, and those who received neither. The groups did not differ on infant characteristics or illness severity. Infants exposed to MgSO4 had more active sleep without rapid eye movement, indicating poorly organized active sleep. The MgSO4 -only group had higher quiet sleep regularity scores and fewer state changes. These findings suggest that fetal exposure to MgSO4 may subtly affect the central nervous system. © 2006 Wiley Periodicals, Inc. Res Nurs Health 29: 269,280, 2006 [source] Current practices in depression careTHE JOURNAL OF CONTINUING EDUCATION IN THE HEALTH PROFESSIONS, Issue S1 2007Albert Yeung MD Abstract Despite improved awareness among the medical community concerning common mental health disorders, the high prevalence of depression in the United States remains unchanged1 and has been compounded by increasing evidence of gaps in mental health care for ethnic and racial minorities.1,2 Thus, there is a strong need for the timely creation of comprehensive educational initiatives aimed at improving the quality of care provided by mental health professionals and primary care physicians. Fundamental to this process is the examination of current treatment standards, as well as identification of practices that require improved physician education. Consistent use of appropriate screening tools, diagnostic accuracy and timeliness, continual assessment of illness severity, adherence to practice guidelines, and individualized patient care need heightened attention to improve outcomes. This article describes the most prevalent types of depression and summarizes current practices in depression care, with an emphasis on treatment standards and opportunities for improved performance. [source] Ambulance Diversion as a Proxy for Emergency Department Crowding: The Effect on Pediatric Mortality in a Metropolitan AreaACADEMIC EMERGENCY MEDICINE, Issue 2 2009Rohit P. Shenoi MD Abstract Objectives:, The objective was to determine the prevalence of emergency department (ED) ambulance diversion among Houston pediatric hospitals and its association with mortality of pediatric patients. Methods:, Hospital diversion and patient data between August 2002 and December 2004 were used to examine the impact of diversion on mortality of children under age 18 years. Patients were assumed to be exposed to ED crowding if diversion and admission or ED arrival times overlapped. Univariate and logistic regression were performed to determine if diversion was associated with mortality while controlling for age, illness severity, injury, and transfer status. Results:, Mean hospital diversion hours as a percentage of operating hours were 10.58 (standard deviation [SD] ± 9). Overall, of 63,780 admissions, there were 4,095 (6.4%) children admitted during diversion. Fewer severely ill patients were admitted during diversion than nondiversion times (odds ratio [OR] = 0.72; 95% confidence interval [CI] = 0.66 to 0.78). The presence of diversion was protective for mortality (OR = 0.51; 95% CI = 0.34 to 0.77) in bivariate analysis. Mortality was associated with presence of major or extreme illness (OR = 60.7; 95% CI = 45.2 to 81.5), injury (OR=1.7; 95% CI = 1.4 to 2.1), and transfer status (OR = 6.3; 95% CI = 5.4 to 7.3). Using conditional logistic regression, major or extreme illness (OR = 50.7; 95% CI = 37.7 to 68.3), injury (OR 3.7; 95% CI = 2.9 to 4.7), and transfer (OR = 2.7; 95% CI = 2.2, 3.2) were associated with mortality, but diversion did not show any association with mortality. After combining ED and inpatient deaths, no association between diversion and mortality was observed. Conclusions:, Hospital diversion due to ED crowding is common in pediatrics. The authors found no evidence of an association between diversion and ED and inpatient pediatric mortality. [source] Battery for assessment of neuropsychological status (RBANS) in schizophrenia: a pilot study in the Spanish population,ACTA NEUROPSYCHIATRICA, Issue 1 2009Juan C. Sanz Objectives:, The aims of this study were to research the following issues in a Spanish population of patients with schizophrenia. (a) The sensitivity and reliability of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) to detect cognitive impairment in schizophrenia. (b) The convergent validity of RBANS on a larger battery of neuropsychological tests sensitive to the cognition disorders typically observed in schizophrenia. (c) The correlates of poor performance in RBANS with clinical features and illness severity. Method:, Thirty schizophrenia patients, 30 non-psychotic patients and 30 healthy participants were assessed using RBANS (form A). We administered a battery of neuropsychological tests and four scales to evaluate patient's clinical status. Results:, Schizophrenia patients and non-psychotic patients performed significantly worse than healthy controls on RBANS, and schizophrenia patients performed slightly worse than non-psychiatric controls, but this difference was not significant. Good inter-test reliability and concurrent validity were found. Only a moderate correlation between RBANS performance and illness severity was observed. Conclusions:, RBANS revealed coherence in identifying cognitive impairment in schizophrenia patients of a different cultural background, and it is shown to be a sensitive, valid and easy-to-perform tool for the neuropsychological assessment of Spanish patients with schizophrenia. [source] Factors Related to Missed Diagnosis of Incidental Scabies Infestations in Patients Admitted Through the Emergency Department to Inpatient ServicesACADEMIC EMERGENCY MEDICINE, Issue 9 2010Ming-Yuan Hong MD ACADEMIC EMERGENCY MEDICINE 2010; 17:958,964 © 2010 by the Society for Academic Emergency Medicine Abstract Objectives:, Scabies is highly contagious and requires prompt diagnosis and implementation of infection control measures to prevent transmission and outbreaks. This study investigated the clinical and administrative correlates associated with missed diagnosis of scabies in an emergency department (ED). Methods:, This was a retrospective study of patients with incidental scabies infestations who were admitted to a university hospital via the ED during a 4-year period. Results:, A total of 135 inpatients were identified as having scabies; among them, 111 patients (82%) had visited the ED. Scabies were diagnosed during the ED stay in 39 of 111 patients (35%), while the diagnosis was missed in the ED in 72 patients (65%). Although no geographic clusters suggestive of nosocomial scabies transmission were registered, 160 medical workers and one hospitalized patient received prophylactic treatment due to direct skin-to-skin contact with inpatient scabies cases during the study period. Overcrowding (odds ratio [OR] = 8.4; 95% confidence interval [CI] = 1.9 to 38.0) and time constraints (OR = 8.2; 95% CI = 1.9 to 34.7) in the ED were associated with a missed diagnosis of scabies during ED stay. Patients with lower illness severity scores were at higher risk for failure to diagnose and to treat scabies prior to hospital admission (OR = 5.7; 95% CI = 1.6 to 20.9). Conclusions:, Missed diagnoses of scabies during ED stay may result in nosocomial spread and increase the unnecessary use of prophylactic treatments. ED overcrowding, time constraints, and less severe illness compromise ED recognition of scabies. Health care workers should be especially alert for signs of scabies infestations under these conditions. [source] Severity of perinatal illness and cerebral cortical growth in preterm infantsACTA PAEDIATRICA, Issue 6 2009Tuula Kaukola Abstract Aim: We have shown previously that the degree of prematurity affects cortical surface area growth. We now addressed the question whether cortical surface area growth after preterm birth is predicted by the severity of peri- and postnatal illness. Methods: Cortical surface area was measured in 269 images from 111 infants born between 23 and 29 weeks and imaged at 23 to 48 weeks gestational age (GA). The severity of perinatal illness was assessed using the clinical risk index for babies score (CRIB I) and the severity of ongoing illness by the presence of chronic lung disease (CLD). The effects on cortical growth were modelled using generalized least-square regression for random effects with Bonferroni correction. To explore the results further we examined CRIB II, C-reactive protein (CRP) on the second day after birth, and time taken to achieve full enteral feeding. Results: Cortical surface area grew by 12.4% per week. Reduced cortical growth was predicted by adverse CRIB I (,0.15% per week per unit) and development of CLD (,1.18% per week). Secondary analysis showed that growth was related to adverse CRIB II (,0.36% per week per unit) and increasing CRP (,0.03% per week per mMol), but not by the time taken to achieve full enteral feeding. Conclusion: After very premature birth illness severity predicts reduced cortical growth. [source] ORIGINAL ARTICLE: Characteristics of plasma NOx levels in severe sepsis: high interindividual variability and correlation with illness severity, but lack of correlation with cortisol levelsCLINICAL ENDOCRINOLOGY, Issue 3 2010J. T. Ho Summary Objectives, Nitric oxide (NO) concentrations are elevated in sepsis and their vasodilatory action may contribute to the development of hyperdynamic circulatory failure. Hydrocortisone infusion has been reported to reduce nitric oxide metabolite (NOx) concentrations and facilitate vasopressor withdrawal in septic shock. Our aim was to determine whether NOx concentrations relate to (i) protocol-driven vasopressor initiation and withdrawal and (ii) plasma cortisol concentrations, from endogenous and exogenous sources. Demonstration of a relation between NOx, cortisol and vasopressor requirement may provide an impetus towards the study of hydrocortisone-mediated NOx suppression as a tool in sepsis management. Design, A prospective study of 62 patients with severe sepsis admitted to the intensive care unit. Measurements, Plasma NOx, total and free cortisol, and corticosteroid-binding globulin (CBG) concentrations were measured and related to protocol-driven vasopressor use for 7 days following admission. Results, Patients who developed septic shock (n = 35) had higher plasma NOx, total and free cortisol, and lower CBG concentrations than the nonseptic shock group (n = 27). Cortisol, CBG and NOx concentrations correlated with illness severity. Free cortisol, and to a lesser extent total cortisol, but not NOx concentrations, predicted septic shock. NOx concentrations were higher in nonsurvivors, and the concentrations were characteristically stable within individuals but marked interindividual differences were only partly accounted for by illness severity or renal dysfunction. NOx concentrations did not correlate with cortisol, did not relate to vasopressor requirement and did not fall after standard dose hydrocortisone, given for clinical indications. Conclusions, Nitric oxide production increased with sepsis severity but did not correlate with plasma cortisol or vasopressor requirement. NOx levels were not suppressed reproducibly by hydrocortisone. High interindividual variability of NOx levels suggests that absolute NOx levels may not be a suitable target for individualized hydrocortisone therapy. [source] Do multiple blood transfusions predispose for a higher rate of non-blood-related infection complications?CLINICAL MICROBIOLOGY AND INFECTION, Issue 7 2002S. R. Leal Noval Allogeneic transfusions of red blood cell (RBC) concentrates have been related to an increase in postoperative infections. Leukocytes present in RBC units might have deleterious effects on the receptor immune system, provoking a state of immunosuppression that favors the development of postoperative infections (TRIM effect). The bioactive substances released by leukocytes in a time-dependent form, accumulating in blood components during storage, might be responsible for the TRIM effect. Multiple observational studies with logistic regression have demonstrated a direct relationship between transfusion and infection. However, several factors related to surgical difficulty and patient illness severity might act as strong confounding variables on the relationship studied. Randomized controlled trials designed to establish a causal relationship between transfusion and infection have yielded contradictory results. While we await new studies, allogeneic transfusions should be considered as a possible risk factor for postoperative infection. [source] | |||||||||||||
