Introduction and objectivesSubstance use is disproportionately high in burn patients and associated with adverse outcomes. Screening methods for substance use disorders may help predict or avoid adverse outcomes.The University of Utah Burn Center records self-reported Alcohol Use Disorders Identification Tests (AUDIT) and Drug Abuse Screening Tests (DAST-10) for all adult burn admissions. This study assessed for association between AUDIT/DAST-10 scores and burn patient outcomes.MethodsA retrospective chart review of adult burn patients admitted to the University of Utah from 05/01/2014–06/30/2017. Patient demographics, injury data, and substance use data were collected and analyzed.Results322 patients underwent AUDIT/DAST-10 screening (n = 322). 56 (17.4%) had positive AUDIT screens (score ≥ 8). 15/50 with alcohol use at time of injury (TOI) had negative AUDIT screens. Median AUDIT score with TOI alcohol use was 12, without TOI alcohol use was 1. 30/55 patients offered alcohol counseling accepted.14 patients (4.3%) had positive DAST-10 screens (score ≥3). 9/25 with drug use at TOI had negative DAST-10 screens. No patients without TOI drug use had DAST-10 scores >2. 9/11 patients offered drug counseling accepted.Mean standardized length of stay (LOS) per TBSA burn injury was 1.7 days for positive AUDIT, 1.6 days for negative AUDIT. Median standardized LOS was 1.4 days for positive DAST-10, 1.7 days for negative DAST-10.ConclusionsAUDIT and DAST-10 screens can identify burn patients with problematic substance use, allowing early intervention. Positive screening scores do not independently predict longer hospital stays, increased wound severity, or treatment noncompliance. 相似文献

PurposeMortality in burn intensive care unit (ICU) has been decreasing and treatment appears to be changing. The aims of this study: (1) examine outcome in burn patients, (2) examine changes in ICU indication and (3) explore the influence of a changing case-mix.MethodsRetrospective study in patients admitted to ICU (1987–2016). Four groups were specified: major burns (≥15% TBSA), inhalation injury with small injury (<15% TBSA, inhalation injury), watchful waiting (<15% TBSA, without inhalation injury), tender loving care (patients withheld from treatment). Logistic regression was performed to evaluate the relation between case-mix and outcome.ResultsOverall mortality decreased to 7%. Mortality of major burns decreased by 15%. The major burn group decreased by 36%. The inhalation injury and watchful waiting group increased by 9% and 21%. The percentage of ventilated patients increased by 14% in the major burn group. 40% of patients were ventilated in the watchful waiting group.ConclusionsAfter correction for case-mix, survival improved, mainly in the major burn group. Case-mix shifted towards inhalation injury and watchful waiting. Growth of the watchful waiting group is not necessarily harmful. However, the increase of mechanical ventilation could be. We suggest raising awareness for risks and consequences of mechanical ventilation. 相似文献

Objectives: Severe grey and white matter volume reductions were found in patients with anorexia nervosa (AN) that were linked to neuropsychological deficits while their underlying pathophysiology remains unclear. For the first time, we analysed the cellular basis of brain volume changes in an animal model (activity-based anorexia, ABA).Methods: Female rats had 24?h/day running wheel access and received reduced food intake until a 25% weight reduction was reached and maintained for 2 weeks.Results: In ABA rats, the volumes of the cerebral cortex and corpus callosum were significantly reduced compared to controls by 6% and 9%, respectively. The number of GFAP-positive astrocytes in these regions decreased by 39% and 23%, total astrocyte-covered area by 83% and 63%. In neurons no changes were observed. The findings were complemented by a 60% and 49% reduction in astrocyte (GFAP) mRNA expression.Conclusions: Volumetric brain changes in ABA animals mirror those in human AN patients. These alterations are associated with a reduction of GFAP-positive astrocytes as well as GFAP expression. Reduced astrocyte functioning could help explain neuronal dysfunctions leading to symptoms of rigidity and impaired learning. Astrocyte loss could constitute a new research target for understanding and treating semi-starvation and AN. 相似文献

The Promoting the Emergence of Advanced Knowledge (PEAK) Relational Training System is an assessment and curriculum tool developed for basic and advanced skills using behavior analytic approaches. The current study evaluated the relationship between intelligence (as measured by IQ scores) and performance on the PEAK assessment with children with autism or other developmental and intellectual disabilities. Each child was administered the PEAK assessment from the Direct Training Module. Scores from this assessment were compared to IQ scores for all participants to assess the relationship between the two measures. Results indicated a strong, significant correlation between scores on standardized IQ tests and scores on the PEAK assessment (r = .759, p < .01). The results demonstrated strong convergent validity and indicate that the PEAK may be a useful assessment and curriculum guide for training language and learning skills to individuals with autism and other developmental disabilities. 相似文献

The HPLC–MS/MS method was developed to profile the dynamics of abscisic acid (ABA) and ABA-glucose ester (ABA-GE) after cloning glycosyltransferase enzyme family gene AtUGT71C5 into Arabidopsis thaliana. By constructing over-expression lines (OE) and down-expression lines (DN), we acquired mutant strains to analyze the function of AtUGT71C5. The multiple-reaction monitoring (MRM) was used for quantitative determination in negative mode. The transition was m/z 263.1→153.0 for ABA ([M–H]+), m/z 425.1→263.0 for ABA-GE ([M–H]+), and m/z 321.0→152.0 for chloramphenicol. The linear range was 0.8684–217.1 ng/mL for ABA and 0.3920–196.0 ng/mL for ABA-GE. The accuracy was 88.0–109.0% for ABA and 86.6–113.0% for ABA-GE; the inter-day and intra-day precisions were less than 5.4% for ABA and 8.9% for ABA-GE, respectively. This method is simple and sensitive enough for determination of ABA and ABA-GE in A. thaliana leaves. All the evidence confirmed the speculation that AtUGT71C5 can mediate abscisic acid homeostasis. 相似文献

In response to drought stress the phytohormone ABA (abscisic acid) induces stomatal closure and, therein, activates guard cell anion channels in a calcium-dependent as well as-independent manner. Two key components of the ABA signaling pathway are the protein kinase OST1 (open stomata 1) and the protein phosphatase ABI1 (ABA insensitive 1). The recently identified guard cell anion channel SLAC1 appeared to be the key ion channel in this signaling pathway but remained electrically silent when expressed heterologously. Using split YFP assays, we identified OST1 as an interaction partner of SLAC1 and ABI1. Upon coexpression of SLAC1 with OST1 in Xenopus oocytes, SLAC1-related anion currents appeared similar to those observed in guard cells. Integration of ABI1 into the SLAC1/OST1 complex, however, prevented SLAC1 activation. Our studies demonstrate that SLAC1 represents the slow, deactivating, weak voltage-dependent anion channel of guard cells controlled by phosphorylation/dephosphorylation. 相似文献
