Study objective
We investigated seasonal prevalence of hyponatremia in the emergency department (ED).Design
A cross-sectional study using clinical chart review.Setting
University Hospital ED, with approximately 28 000 patient visits a year.Type of participants
We reviewed 15 049 patients, subdivided in 2 groups: the adult group consisting of 9822 patients aged between 18 and 64 years old and the elderly group consisting of 5227 patients aged over 65 years presenting to the ED between January 1st, 2014 and December 31st, 2015.Intervention
Emergency patients were evaluated for the presence of hyponatremia by clinical chart review.Measurements and main results
Hyponatremia was defined as a serum sodium level < 135 mmol/l. Mean monthly prevalence of hyponatremia was of 3.74 ± 0.5% in the adult group and it was significantly increased to 10.3 ± 0.7% in the elderly group (p < 0.05 vs adults). During the summer, hyponatremia prevalence was of 4.14 ± 0.2% in adult and markedly increased to 12.52 ± 0.7% (zenith) in elderly patients (p < 0.01 vs adult group; p < 0.05 vs other seasons in elderly group). In the elderly group, we reported a significant correlation between weather temperature and hyponatremia prevalence (r: 0.491; p < 0.05).Conclusion
We observed a major influence of climate on the prevalence of hyponatremia in the elderly in the ED. Decline in renal function, salt loss, reduced salt intake and increased water ingestion could all contribute to developing hyponatremia in elderly patients during the summer. These data could be useful for emergency physicians to prevent hot weather-induced hyponatremia in the elderly. 相似文献2.

Background
Hypoxemia increases the risk of intubation markedly. Such concerns are multiplied in the emergency department (ED) and during retrieval where patients may be unstable, preparation or preoxygenation time limited and the environment uncontrolled. Apneic oxygenation is a promising means of preventing hypoxemia in this setting.Aim
To test the hypothesis that apnoeic oxygenation reduces the incidence of hypoxemia during endotracheal intubation in the ED and during retrieval.Methods
We undertook a systematic review of six databases for all relevant studies published up to November 2016. Included studies evaluated apneic oxygenation during intubation in the ED and during retrieval. There were no exemptions based on study design. All studies were assessed for level of evidence and risk of bias. The Review Manager 5.3 software was used to perform meta-analysis of the pooled data.Results
Six trials and a total 1822 cases were included for analysis. The study found a significant reduction in the incidence of desaturation (RR = 0.76, p = 0.002) and critical desaturation (RR = 0.51, p = 0.01) when apneic oxygenation was implemented. There was also a significant improvement in first pass intubation success rate (RR = 1.09, p = 0.004).Conclusion
Apneic oxygenation may reduce patient hypoxemia during intubation performed in the ED and during retrieval. It also improves intubation first-pass success rate in this setting. 相似文献3.

Introduction
There is a lack of information regarding intraosseous (IO) administration of tranexamic acid (TXA). Our hypothesis was that a single bolus IO injection of TXA will have a similar pharmacokinetic profile to TXA administered at the same dose IV.Methods
Sixteen male Landrace cross swine (mean body weight 27.6 ± 2.6 kg) were divided into an IV group (n = 8) and an IO group (n = 8). Each animal received 30 mg/kg TXA via an IV or IO catheter, respectively. Jugular blood samples were collected for pharmacokinetic analysis over a 3 h period. The maximum TXA plasma concentration (Cmax) and corresponding time as well as distribution half-life, elimination half-life, area under the curve, plasma clearance and volume of distribution were calculated. One- and two-way analysis of variance for repeated measures (time, group) with Tukey's and Bonferonni post hoc tests were used to compare TXA plasma concentrations within and between groups, respectively.Results
Plasma concentrations of TXA were significantly higher (p < 0.0001) in the IV group during the TXA infusion. Cmax occurred at 4 min after initiation of the bolus in the IV group (9.36 ± 3.20 ng/μl) and at 5 min after initiation of the bolus in the IO group (4.46 ± 0.49 ng/μl). Plasma concentrations were very similar from the completion of injection onwards. There were no significant differences between the two administration routes for any other pharmacokinetic variables measured.Conclusion
The results of this study support pharmacokinetic bioequivalence of IO and IV administration of TXA. 相似文献4.

Background and purpose
Accurate diagnosis of acute aortic dissection (AAD) is sometimes difficult because of accompanying central nervous system (CNS) symptoms. The purpose of this study was to investigate the clinical characteristics of Type A AAD (TAAAD) with CNS symptoms.Methods
We retrospectively reviewed the medical records of 8403 patients ambulanced to our emergency and critical care center between April 2009 and May 2014.Results
We identified 59 TAAAD patients for the analysis (mean age, 67.3 ± 10.5 years; 37 (62.0%) male). Eleven patients (18.6%) presented CNS symptoms at the onset of TAAAD, and these patients complained less frequently of typical chest and back pain than those without CNS symptoms (p < 0.0001). Initial systolic and diastolic blood pressure were lower (p = 0.003, and p = 0.049, respectively) and involvement of the supra-aortic artery was more frequent in patients with CNS symptoms (p < 0.0001).Conclusion
Because CNS symptom can mask chest and back pain caused by TAAAD, physicians should always consider the possibility of TAAAD in patients with CNS symptoms in emergency medicine settings. 相似文献5.

Study objective
We investigated the serum sodium correction rate on length of hospitalization and survival rate, in severe chronic hyponatremic patients at the Emergency Department (ED).Design
An observational study using clinical chart review.Setting
The ED of the University Hospital of Marcianise, Caserta, Italy with approximately 30,000 patients visits a year.Type of participants
We reviewed sixty-seven patients with severe hyponatremia subdivided in 2 subgroups: group A consisting of 35 patients with serum sodium correction rate < 0.3 mmol/h and group B consisting of 32 patients with serum sodium correction rate between < 0.5 and ≥ 0.3 mmol/h.Intervention
Emergency patients were evaluated for serum sodium correction rate for hyponatremia by clinical chart review.Measurements and main results
Severe hyponatremia was defined as a serum sodium level < 120 mmol/l. Mean serum sodium correction rate of hyponatremia was of 0.17 ± 0.09% in group A and 0.41 ± 0.05% in group B (p < 0.001 vs group A). The length of hospital stay was 10.7 ± 3.7 days for group A, and it was significantly decreased to 3.8 ± 0.4 days for group B (p < 0.005 vs group A). In addition we observed that correction rate of hyponatremia in group A was associated with a significantly lower survival rate (25%) in comparison to group B (60%) (p < 0.001 vs group A).Conclusion: We observed that serum sodium correction rate ≥ 0.3 and < 0.5 mmol/h was associated with a shorter length of hospital stay and a major survival rate. 相似文献6.

Background
Motor vehicle–related injuries (including off-road) are the leading cause of traumatic brain injury (TBI) and acute traumatic spinal cord injury in the United States.Objectives
To describe motocross-related head and spine injuries of adult patients presenting to an academic emergency department (ED).Methods
We performed an observational cohort study of adult ED patients evaluated for motocross-related injuries from 2010 through 2015. Electronic health records were reviewed and data extracted using a standardized review process.Results
A total of 145 motocross-related ED visits (143 unique patients) were included. Overall, 95.2% of patients were men with a median age of 25 years. Sixty-seven visits (46.2%) were associated with head or spine injuries. Forty-three visits (29.7%) were associated with head injuries, and 46 (31.7%) were associated with spine injuries. Among the 43 head injuries, 36 (83.7%) were concussions. Seven visits (16.3%) were associated with at least 1 head abnormality identified by computed tomography, including skull fracture (n = 2), subdural hematoma (n = 1), subarachnoid hemorrhage (n = 4), intraparenchymal hemorrhage (n = 3), and diffuse axonal injury (n = 3). Among the 46 spine injuries, 32 (69.6%) were acute spinal fractures. Seven patients (4.9%) had clinically significant and persistent neurologic injuries. One patient (0.7%) died, and 3 patients had severe TBIs.Conclusion
Adult patients evaluated in the ED after motocross trauma had high rates of head and spine injuries with considerable morbidity and mortality. Almost half had head or spine injuries (or both), with permanent impairment for nearly 5% and death for 0.7%. 相似文献7.

Objective
To evaluate occurrence of cerebellar stroke in Emergency Department (ED) presentations of isolated dizziness (dizziness with a normal exam and negative neurological review of systems).Methods
A 5-year retrospective study of ED patients presenting with a chief complaint of “dizziness or vertigo”, without other symptoms or signs in narrative history or on exam to suggest a central nervous system lesion, and work-up included a brain MRI within 48 h. Patients with symptoms commonly peripheral in etiology (nystagmus, tinnitus, gait instability, etc.) were included in the study. Patient demographics, stroke risk factors, and gait assessments were recorded.Results
One hundred and thirty-six patients, who had a brain MRI for isolated dizziness, were included. There was a low correlation of gait assessment between ED physician and Neurologist (49 patients, Spearman's correlation r2 = 0.17). Based on MRI DWI sequence, 3.7% (5/136 patients) had acute cerebellar strokes, limited to or including, the medial posterior inferior cerebellar artery vascular territory. In the 5 cerebellar stroke patients, mean age, body mass index (BMI), hemoglobin A1c, gender distribution, and prevalence of hypertension were similar to the non-cerebellar stroke patient group. Mean LDL/HDL ratio was 3.63 ± 0.80 and smoking prevalence was 80% in the cerebellar stroke group compared to 2.43 ± 0.79 and 22% (respectively, p values < 0.01) in the non-cerebellar stroke group.Conclusions
Though there was preselection bias for stroke risk factors, our study suggests an important proportion of cerebellar stroke among ED patients with isolated dizziness, considering how common this complaint is. 相似文献8.

Objective
Routine CT for patients with acute flank pain has not been shown to improve patient outcomes, and it may unnecessarily expose patients to radiation and increased costs. As preliminary steps toward the development of a guideline for selective CT, we sought to determine the prevalence of clinically important outcomes in patients with acute flank pain and derive preliminary decision rules.Methods
We analyzed data from a randomized trial of CT vs. ultrasonography for patients with acute flank pain from 15 EDs between October 2011 and February 2013. Clinically important outcomes were defined as inpatient admission for ureteral stones and alternative diagnoses. Clinically important stones were defined as stones requiring urologic intervention. We sought to derive highly sensitive decision rules for both outcomes.Results
Of 2759 participants, 236 (8.6%) had a clinically important outcome and 143 (5.2%) had a clinically important stone. A CDR including anemia (hemoglobin < 13.2 g/dl), WBC count > 11 000/μl, age > 42 years, and the absence of CVAT had a sensitivity of 97.9% (95% CI 94.8–99.2%) and specificity of 18.7% (95% 17.2–20.2%) for clinically important outcome. A CDR including hydronephrosis, prior history of stone, and WBC count < 8300/μl had a sensitivity of 98.6% (95% CI 94.5–99.7%) and specificity of 26.0% (95% 24.2–27.7%) for clinically important stone.Conclusions
We determined the prevalence of clinically important outcomes in patients with acute flank pain, and derived preliminary high sensitivity CDRs that predict them. Validation of CDRs with similar test characteristics would require prospective enrollment of 2100 patients. 相似文献9.

Background
Respiratory syncytial virus (RSV) and influenza have varying degree of seasonal overlap.Objective
To determine the prevalence of co-infection of RSV and influenza compared to the prevalence of those infections independently when both are in season.Methods
This was a retrospective cross-sectional study of children evaluated between July 2010 and June 2013 for viral respiratory infection using multiplex PCR. Seasonality was defined retrospectively as weeks when > 2% of the total annual positive tests were obtained and was calculated for influenza A, influenza B, and RSV independently. Periods of overlapping seasonality of RSV and influenza A and RSV and influenza B were identified. The expected incidences of co-infection were modeled as the product of the incidences of the individual viruses.Results
13,664 specimens were sent for PCR during the study period. Over all 3 seasons, RSV overlapped with influenza A and B for 22 and 18 weeks, respectively; in 2011–12, RSV overlapped with neither influenza A nor B. Based on modeling, there were 6–7 fold fewer cases of RSV/influenza co-infection observed than expected: RSV/influenza A 77 vs. 12, (p ≤ 0.001; RSV/influenza B 76 vs. 11 (p ≤ 0.001).Conclusions
The observed incidence of co-infectivity of RSV and influenza was significantly less than the expected incidence even when both were co-circulating. In light of these data, it may be reasonable to forgo rapid influenza testing or empiric antiviral treatment for children whom rapid RSV testing is positive and who are at low risk of influenza-related complications, especially in times of antiviral therapy shortages. 相似文献10.

Objective
This research is to study if quick administration of adrenaline on OHCA prior to hospitalization has an effect on improving CPC1-2 at one month.Methodology
A total 13,326 cases were extracted from 2011 to 2014 Utstein data for this retrospective cohort study, also, EMT reached the patients within 16 min after 119 called and adrenaline was then administered within 22 min of after contact.Patients divided into two groups
Patients were contacted within 8 min of the 119 call (n = 6956), and were contacted between 8 and 16 min after the call (n = 6370). Further divided into groups in which the adrenaline was administered within/without 10 min after contact. Primary outcome was the rate of a good prognosis for cerebral performance (CPC1-2) at 1 month and secondary outcome was the return of spontaneous circulation (ROSC) rate.Results
The odds ratio of the CPC1-2 at 1 month by the EMS reached within 8 min after 119 call and then adrenaline administered within 10 min was 2.12 (1.54–2.92).Those reached between 8 and 16 min was 2.66 (1.97–3.59). However, the ROSC rate was 2.00 (1.79–2.25) for those reached within 8 min and also 2.00 (1.79–2.25) for those reached between 8 min and 16 min.Considerations
In cases of OHCA, it appears that the CPC1-2 rate after 1 month can be improved even in cases where the victim is reached > 8 min after the 119 call, as long as the victim is reached within 16 min and emergency responders administer the adrenaline as quickly as possible. 相似文献11.

Background
Though hospitals' operational continuity is crucial, full institutional evacuation may at times be unavoidable. The study's objective was to establish criteria for discharge of patients during complete emergency evacuation and compare scope of patients suitable for discharge pre/post implementation of criteria.Basic procedures
Standards for patient discharge during an evacuation were developed based on literature and disaster managers. The standards were reviewed in a two-round Delphi process. All hospitals in Israel were requested to identify inpatients' that could be released home during institutional evacuation. Potential discharges were compared in 2013–2014, before and after formulation of discharge criteria.Main findings
Consensus exceeding 80% was obtained for four out of five criteria after two Delphi cycles. Average projected discharge rate before and after formulation of criteria was 34.2% and 42.9%, respectively (p < 0.001). Variance in potential dischargeable patients was 31-fold less in 2014 than in 2013 (MST = 8,452 versus MST = 264,366, respectively; p < 0.001). Differences were found between small, medium and large hospitals in mean rate of dischargeable patients: 52.1%, 41.5% and 42.2%, respectively (p = 0.001).Principle conclusions
The study's findings enable to forecast the extent of patients that may be released home during full emergency evacuation of a hospital; thereby facilitating preparedness of contingency plans. 相似文献12.

Aim
Bacteremia is an uncommon complication of urinary tract infection (UTI). The aim of this study was to identify risk factors for bacteremic UTI in pediatric patients.Methods
The medical records of all pediatric patients with UTI between 2013 and 2014 were retrospectively reviewed. Pediatric patients with accompanying bacteremia were compared with pediatric patients with no bacteremia.Results
Five hundred twenty-seven cases of UTI were identified. Blood cultures were taken in 464, 26 (5.6%) of which also were bacteremic. Pediatric patients with bacteremia were more likely to be male (58% vs 28%, P < .01), to be younger than 3 months (54% vs 31%, P = .02), and to have higher creatinine (average 0.77 ± 0.97 vs 0.34 ± 0.24, P < .01). Pediatric patients with bacteremia had higher rate of underlying urologic conditions. The following variables were included in multivariate analysis: age < 3 months, sex, ethnicity, method of urine collection, creatinine, and underlying urologic conditions. Only creatinine (odds ratio, 3.67; 95% confidence interval, 1.69-8.11) was found as an independent risk factor for bacteremia.Conclusions
High creatinine at presentation is a risk factor that might aid in early identification of pediatric patients with high risk for bacteremia and its complications. 相似文献13.

Background
Patients with traumatic intracranial hemorrhage and mild traumatic brain injury (mTIH) receive broadly variable care which often includes transfer to a trauma center, neurosurgery consultation and ICU admission. However, there may be a low risk cohort of patients who can be managed without utilizing such significant resources.Objective
Describe mTIH patients who are at low risk of clinical or radiographic decompensation and can be safely managed in an ED observation unit (EDOU).Methods
Retrospective evaluation of patients age ≥ 16, GCS ≥ 13 with ICH on CT. Primary outcomes included clinical/neurologic deterioration, CT worsening or need for neurosurgery.Results
1185 consecutive patients were studied. 814 were admitted and 371 observed patients (OP) were monitored in the EDOU or discharged from the ED after a period of observation. None of the OP deteriorated clinically. 299 OP (81%) had a single lesion on CT; 72 had mixed lesions. 120 patients had isolated subarachnoid hemorrhage (iSAH) and they did uniformly well. Of the 119 OP who had subdural hematoma (SDH), 6 had worsening CT scans and 3 underwent burr hole drainage procedures as inpatients due to persistent SDH without new deficit. Of the 39 OP who had cerebral contusions, 3 had worsening CT scans and one required NSG admission. No patient returned to the ED with a complication. Follow-up was obtained on 81% of OP. 2 patients with SDH required burr hole procedure > 2 weeks after discharge.Conclusions
Patients with mTIH, particularly those with iSAH, have very low rates of clinical or radiographic deterioration and may be safe for monitoring in an emergency department observation unit. 相似文献14.

Background
Acute dyspnea affects a large heterogeneous patient group with high mortality and readmission rates.Purpose
To investigate if cardiometabolic biomarkers and clinical characteristics predict readmission and death in patients hospitalized for acute dyspnea.Methods
65 dyspnea patients at a general internal medicine ward were followed for six months. The combined endpoint was readmission or death.Measurements and results
Cardiometabolic biomarkers at admission were related to the endpoint in Cox proportional hazard models (adjusted for sex, age, oxygen saturation, respiratory rate and C-reactive protein (CRP)). The biomarkers tissue-type plasminogen activator (tPA), prolactin (PRL), tumor necrosis factor receptor superfamily member 6 (FAS) and C-C motif chemokine 3 (CCL3) were independently and significantly related to the endpoint and combined into a biomarker risk score (BRS). Each SD increment of the BRS conferred a hazard ratio (HR) of 2.13 (1.39–3.27) P = 0.001. The top vs bottom tertile of the BRS conferred a HR of 4.75 (1.93–11.68) P = 0.001. Dyspnea severity was also associated with worse outcome, HR = 3.43 (1.28–9.20) P = 0.014. However, when mutually adjusted the BRS remained significant (P = 0.004) whereas dyspnea severity was not. The BRS was related to the endpoint among patients with mild to moderate dyspnea (P = 0.016) but not among those with severe dyspnea.Conclusion
A score of tPA, PRL, FAS and CCL3 predicts 6-month death and readmission in patients hospitalized for acute dyspnea and may prove useful to optimize length of stay and follow-up. Although the BRS outweighs dyspnea severity in prediction of the endpoint, its prognostic role is strongest in mild-moderate dyspnea. 相似文献15.

Introduction
Blunt trauma is a leading cause of pediatric morbidity. We compared injuries, interventions and outcomes of acute pediatric blunt torso trauma based on intent.Methods
We analyzed de-identified data from a prospective, multi-center emergency department (ED)-based observational cohort of children under age eighteen. Injuries were classified based on intent (unintentional/inflicted). We compared demographic, physical and laboratory findings, ED disposition, hospitalization, need for surgery, 30-day mortality, and cause of death between groups using Chi-squared or Fisher's test for categorical variables, and Mann-Whitney test for non-normal continuous factors comparing median values and interquartile ranges (IQR).Results
There were 12,044 children who sustained blunt torso trauma: Inflicted = 720 (6%); Unintentional = 9563 (79.4%); Indeterminate = 148 (1.2%); Missing = 1613 (13.4%). Patients with unintentional torso injuries significantly differed from those with inflicted injuries in median age in years (IQR) [10 (5, 15) vs. 14 (8, 16); p-value < 0.001], race, presence of pelvic fractures, hospitalization and need for non-abdominal surgery. Mortality rates did not differ based on intent. Further adjustment using binary, logistic regression revealed that the risk of pelvic fractures in the inflicted group was 96% less than the unintentional group (OR: 0.04; 95%CI: 0.01–0.26; p-value = 0.001).Conclusions
Children who sustain acute blunt torso trauma due to unintentional causes have a significantly higher risk of pelvic fractures and are more likely to be hospitalized compared to those with inflicted injuries. 相似文献16.

Objectives
The depressed heart function is the main complication to cause death of septic patients in clinic. It is urgent to find effective interventions for this intractable disease. In this study, we investigated whether butyrate could be protective for heart against sepsis and the underlying mechanism.Methods
Mice were randomly divided into three groups. Model group challenged with LPS (30 mg/kg, i.p.) only. Butyrate group received butyrate (200 mg/kg·d) for 3 days prior to LPS administration (30 mg/kg). Normal group received saline only. 6 h and 12 h after LPS administration were chosen for detection the parameters to estimate the effects or mechanism of butyrate pretreatment on heart of sepsis.Results
The data showed that septic heart depression was attenuated by butyrate pretreatment through improvement of heart function depression (P < 0.01) and reduction of morphological changes of myocardium. The overexpression of proinflammatory factors, TNF-α, IL-6 and LTB4, in heart tissues induced by sepsis was significantly alleviated by butyrate pretreatment (P < 0.01). As oxidative stress indicators, SOD and CAT activity, and MDA content in heart were deteriorated by LPS challenge, which was noticeably ameliorated by butyrate pretreatment (P < 0.01 or P < 0.05).Conclusions
In conclusion, pretreatment with butyrate attenuated septic heart depression via anti-inflammation and anti-oxidation. 相似文献17.

Purpose
The objective of this study was to assess the efficacy of paracetamol (acetaminophen) on body temperature in acute stroke.Methods
Medline, Cochrane Central Register of Controlled Trials, EMBASE, Chinese BioMedical Literature Database, China National Knowledge Infrastructure, and the World Health Organization (WHO) International Clinical Trials Registry Platform were searched electronically. Relevant journals and references of studies included were hand-searched for randomized controlled trials (RCT) and controlled clinical trials (CCT) regarding the efficacy of paracetamol (acetaminophen) on body temperature in acute stroke. Two reviewers independently performed data extraction and quality assessment. Data were analyzed using RevMan 5.3 software by the Cochrane Collaboration.Results
Five studies were included. To compare the efficacy of paracetamol (acetaminophen) in acute stroke, the pooled RR (Risk Ratio) and its 95% CI of body temperature reduction at 24 h from the start of treatment were ? 0.3 (95% CI: ? 0.52 to ? 0.08), with statistical significance (P = 0.007). Consistently, the pooled RR (Risk Ratio) and its 95% CI of body temperature at 24 h from the start of treatment were ? 0.22 (? 0.29, ? 0.15), with statistical significance (P < 0.00001). When analyzing the body temperature reduction after 5 days from the start of treatment, the pooled RR (Risk Ratio) and its 95% CI were 0.04 (95% CI: ? 0.20 to 0.29), with no statistical significance (P = 0.73). For functional outcome (mRS ≤ 2) analysis, the pooled RR and its 95% CI were 1.08 (0.88, 1.32), with no statistical significance (P = 0.45). In addition, the difference of serious adverse events between acetaminophen and placebo was 0.86 (95% CI: 0.62 to 1.2), with no statistical significance (P = 0.27).Conclusion
Acetaminophen was revealed to have some favorable influence in body temperature reduction in acute stroke, but showed no important effect on improving functional outcome and reducing adverse events of patients.What this paper adds
What is already known on this subject?Paracetamol (acetaminophen) is one of the most commonly used antipyretic drugs and has some capability to reduce body temperature through acting on central nervous system.What this study adds
Acetaminophen showed some capability to decrease body temperature for acute stroke.Acetaminophen could not improve functional outcome and reduce adverse events of patients with acute stroke. 相似文献18.

Introduction
The incidence of heart failure (HF) has reached epidemic levels in western populations, and the majority of these patients are admitted to hospitals through the emergency department (ED). We aimed to aid clinicians assessing natriuretic peptide (NP) levels in cases with suspected HF. In this study, we investigated the effect of anemia on amino-terminal pro-BNP (NT-proBNP) and on B-type natriuretic peptide (BNP) levels.Methods
This retrospective study examined patients who were admitted to the ED with suspected HF. After admission, the treating physician requested complete blood count and creatinine tests with NT-proBNP (n = 2.637) or BNP (n = 11.159). The exclusion criteria were used to minimize the factors that could affect the NT-proBNP and BNP results. We examined the data using the Mann-Whitney U test, Chi-square test, Spearman correlation test, and multivariate linear regression analyses.Results
The NT-proBNP and BNP levels were statistically higher in the groups with anemia (p = 0.016 and p = 0.009, respectively). There was a statistically significant negative correlation between hemoglobin and NP levels (r = ? 0.272, p < 0.001 for NT-proBNP and r = ? 0.179, p < 0.001 for BNP). The results indicated that advanced age and low hemoglobin levels were significantly associated with the increase in NT-proBNP (p = 0.024 and p = 0.004, respectively). Advanced age, low hemoglobin and low GFR-MDRD levels were significantly associated with the increase in BNP (p < 0.001, p = 0.002 and p = 0.013, respectively).Discussion
The data suggest that clinicians examining patients admitted to the ED with suspected HF should consider that anemia could lead to increases in NT-proBNP and BNP levels. 相似文献19.

Background
Accurate temperature readings, often obtained rectally, are an important part of the initial evaluation of pediatric patients in the Emergency Department. Temporal artery thermometry (TAT) is one way to noninvasively measure temperature. We sought to compare the accuracy of axillary and temporal artery temperatures compared to rectal.Methods
This prospective study included children age 0–36 months presenting to the Emergency Department of a large military treatment facility. Rectal, axillary, and temporal artery temperatures were obtained. Test characteristics (sensitivity, specificity, NPV, PPV) were reported. The effect of cutoff values 99.9 °F, 100.4 °F, and 102.2 °F on test characteristics were also evaluated.Results
The sensitivities of axillary and temporal artery thermometry to detect rectal fever is 11.5% and 61.5% respectively. Cutoff values did not significantly alter test characteristics. In this study, temporal artery thermometry was 0.2 °C lower than rectal temperature, axillary measurement was 0.9 °C below the reference standard. Mean temperature difference in the febrile group between TAT and rectal thermometry was > 0.5 °C compared with a mean temperature difference 0.05 °C in afebrile patients.Conclusion
The findings of our study do not support using axillary thermometry to screen pediatric patients for fever in the emergency department. TAT cannot be recommended as a rectal thermometry replacement where height and duration of fever are used in pediatric disease prediction models. TAT may have a role in screening for fever in the appropriate pediatric patient population like primary orthopedic or trauma presentations where the balance between device precision, data capture and patient comfort may favor use of TAT. 相似文献20.
