RESUMO
Cellular therapy is a promising investigational modality to enhance poststroke recovery. We conducted a single-arm, phase I clinical trial to determine the safety and feasibility of intravenous (IV) administration of autologous bone marrow mononuclear cells (MNCs) after acute ischemic stroke (AIS). Patients with moderate severity of AIS underwent bone marrow harvest followed by IV reinfusion of MNCs within 24-72 hours of onset. A target dose of 10 million cells per kilogram was chosen based on preclinical data. Patients were followed up daily during hospitalization and at 1, 3, 6, 12, and 24 months for incidence of adverse events using laboratory, clinical (12 months), and radiological (24 months) parameters. The trial was powered to detect severe adverse events (SAEs) with incidences of at least 10% and planned to enroll 30 patients. Primary outcomes were study-related SAEs and the proportion of patients successfully completing study intervention. A propensity score-based matched control group was used for the estimation of effect size (ES) for day-90 modified Rankin score (mRS). There were no study-related SAEs and, based on a futility analysis, enrolment was stopped after 25 patients. All patients successfully completed study intervention and most received the target dose. Secondary analysis estimated the ES to be a reduction of 1 point (95% confidence interval: 0.33-1.67) in median day-90 mRS for treated patients as compared with the matched control group. Bone marrow harvest and infusion of MNCs is safe and feasible in patients with AIS. The estimated ES is helpful in designing future randomized controlled trials. Stem Cells 2019;37:1481-1491.

BACKGROUND: Pneumonia is the leading cause of sepsis. In 2016, the 3rd International Consensus Conference for Sepsis released the Quick Sepsis-Related Organ Failure Assessment (qSOFA) to identify risk for poor outcomes in sepsis. OBJECTIVE: We sought to externally validate qSOFA in emergency department (ED) patients with pneumonia and compare the accuracy of qSOFA to systemic inflammatory response syndrome score (SIRS), Confusion, Respiratory Rate and Blood Pressure (CRB), Confusion, Respiratory Rate, Blood Pressure and Age (CRB-65), and DS CRB-65, which is based on the CRB-65 score and includes two additional items-presence of underlying comorbid disease and blood oxygen saturation. METHODS: A subgroup analysis of U.S. Critical Illness and Injury Trials Group (USCIITG-Lung Injury Prevention Study [LIPS]; ClinicalTrials.gov ID: NCT00889772) prospective cohort. The primary outcome was in-hospital mortality. Secondary outcomes were measures of intensive care unit (ICU) utilization. Sensitivity, specificity, and area under the curve (AUC) were reported. RESULTS: From March to August 2009, 5584 patients were enrolled; 713 met inclusion criteria. Median age was 61 years (interquartile range 49-75 years). SIRS criteria had the highest sensitivity for death (89%) and lowest specificity (25%), while CRB had the highest specificity (88%) and lowest sensitivity (31%), followed by qSOFA (80% and 53%, respectively). This trend was maintained for the secondary outcomes. There was no significant difference in the AUC for death using qSOFA (AUC 0.75; 95% confidence interval [CI] 0.66-0.84), SIRS (AUC 0.70; 95% CI 0.61-0.78), CRB (AUC 0.71; 95% CI 0.62-0.80), CRB-65 (AUC 0.71; 95% CI 0.63-0.80), and DS CRB-65 (AUC 0.73; 95% CI 0.64-0.82). CONCLUSIONS: In this multicenter observational study of ED patients hospitalized with pneumonia, we found no significant differences between qSOFA and SIRS for predicting in-hospital death. In addition, several popular pneumonia-specific severity scores performed nearly identically to qSOFA score in predicting death and ICU utilization. Validation is needed in a larger sample.

Preclinical studies using bone marrow derived cells to treat traumatic brain injury have demonstrated efficacy in terms of blood-brain barrier preservation, neurogenesis, and functional outcomes. Phase 1 clinical trials using bone marrow mononuclear cells infused intravenously in children with severe traumatic brain injury demonstrated safety and potentially a central nervous system structural preservation treatment effect. This study sought to confirm the safety, logistic feasibility, and potential treatment effect size of structural preservation/inflammatory biomarker mitigation in adults to guide Phase 2 clinical trial design. Adults with severe traumatic brain injury (Glasgow Coma Scale 5-8) and without signs of irreversible brain injury were evaluated for entry into the trial. A dose escalation format was performed in 25 patients: 5 controls, followed 5 patients in each dosing cohort (6, 9, 12 ×106 cells/kg body weight), then 5 more controls. Bone marrow harvest, cell processing to isolate the mononuclear fraction, and re-infusion occurred within 48 hours after injury. Patients were monitored for harvest-related hemodynamic changes, infusional toxicity, and adverse events. Outcome measures included magnetic resonance imaging-based measurements of supratentorial and corpus callosal volumes as well as diffusion tensor imaging-based measurements of fractional anisotropy and mean diffusivity of the corpus callosum and the corticospinal tract at the level of the brainstem at 1 month and 6 months postinjury. Functional and neurocognitive outcomes were measured and correlated with imaging data. Inflammatory cytokine arrays were measured in the plasma pretreatment, posttreatment, and at 1 and 6 month follow-up. There were no serious adverse events. There was a mild pulmonary toxicity of the highest dose that was not clinically significant. Despite the treatment group having greater injury severity, there was structural preservation of critical regions of interest that correlated with functional outcomes. Key inflammatory cytokines were downregulated. Treatment of severe, adult traumatic brain injury using an intravenously delivered autologous bone marrow mononuclear cell infusion is safe and logistically feasible. There appears to be a treatment signal as evidenced by central nervous system structural preservation, consistent with previous pediatric trial data. Inflammatory biomarkers are downregulated after cell infusion. Stem Cells 2016 Video Highlight: https://youtu.be/UiCCPIe-IaQ Stem Cells 2017;35:1065-1079.

IMPORTANCE: There is limited information about the effect of erythropoietin or a high hemoglobin transfusion threshold after a traumatic brain injury. OBJECTIVE: To compare the effects of erythropoietin and 2 hemoglobin transfusion thresholds (7 and 10 g/dL) on neurological recovery after traumatic brain injury. DESIGN, SETTING, AND PARTICIPANTS: Randomized clinical trial of 200 patients (erythropoietin, n = 102; placebo, n = 98) with closed head injury who were unable to follow commands and were enrolled within 6 hours of injury at neurosurgical intensive care units in 2 US level I trauma centers between May 2006 and August 2012. The study used a factorial design to test whether erythropoietin would fail to improve favorable outcomes by 20% and whether a hemoglobin transfusion threshold of greater than 10 g/dL would increase favorable outcomes without increasing complications. Erythropoietin or placebo was initially dosed daily for 3 days and then weekly for 2 more weeks (n = 74) and then the 24- and 48-hour doses were stopped for the remainder of the patients (n = 126). There were 99 patients assigned to a hemoglobin transfusion threshold of 7 g/dL and 101 patients assigned to 10 g/dL. INTERVENTIONS: Intravenous erythropoietin (500 IU/kg per dose) or saline. Transfusion threshold maintained with packed red blood cells. MAIN OUTCOMES AND MEASURES: Glasgow Outcome Scale score dichotomized as favorable (good recovery and moderate disability) or unfavorable (severe disability, vegetative, or dead) at 6 months postinjury. RESULTS: There was no interaction between erythropoietin and hemoglobin transfusion threshold. Compared with placebo (favorable outcome rate: 34/89 [38.2%; 95% CI, 28.1% to 49.1%]), both erythropoietin groups were futile (first dosing regimen: 17/35 [48.6%; 95% CI, 31.4% to 66.0%], P = .13; second dosing regimen: 17/57 [29.8%; 95% CI, 18.4% to 43.4%], P < .001). Favorable outcome rates were 37/87 (42.5%) for the hemoglobin transfusion threshold of 7 g/dL and 31/94 (33.0%) for 10 g/dL (95% CI for the difference, -0.06 to 0.25, P = .28). There was a higher incidence of thromboembolic events for the transfusion threshold of 10 g/dL (22/101 [21.8%] vs 8/99 [8.1%] for the threshold of 7 g/dL, odds ratio, 0.32 [95% CI, 0.12 to 0.79], P = .009). CONCLUSIONS AND RELEVANCE: In patients with closed head injury, neither the administration of erythropoietin nor maintaining hemoglobin concentration of greater than 10 g/dL resulted in improved neurological outcome at 6 months. The transfusion threshold of 10 g/dL was associated with a higher incidence of adverse events. These findings do not support either approach in this setting. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00313716.

Importance: Access to COVID-19 testing is critical to reducing transmission and supporting early treatment decisions; when made accessible, the timeliness of testing may also be an important metric in mitigating community spread of the infection. While disparities in transmission and outcomes of COVID-19 have been well documented, the extent of timeliness of testing and the association with demographic factors is unclear. Objectives: To evaluate demographic factors associated with delayed COVID-19 testing among health care personnel (HCP) during the COVID-19 pandemic. Design, Setting, and Participants: This cross-sectional study used data from the Preventing Emerging Infections Through Vaccine Effectiveness Testing study, a multicenter, test-negative, case-control vaccine effectiveness study that enrolled HCP who had COVID-19 symptoms and testing between December 2020 and April 2022. Data analysis was conducted from March 2022 to Junne 2023. Exposure: Displaying COVID-19-like symptoms and polymerase chain reaction testing occurring from the first day symptoms occurred up to 14 days after symptoms occurred. Main Outcomes and Measures: Variables of interest included patient demographics (sex, age, and clinical comorbidities) and COVID-19 characteristics (vaccination status and COVID-19 wave). The primary outcome was time from symptom onset to COVID-19 testing, which was defined as early testing (≤2 days) or delayed testing (≥3 days). Associations of demographic characteristics with delayed testing were measured while adjusting for clinical comorbidities, COVID-19 characteristics, and test site using multivariable modeling to estimate relative risks and 95% CIs. Results: A total of 5551 HCP (4859 female [82.9%]; 1954 aged 25-34 years [35.2%]; 4233 non-Hispanic White [76.3%], 370 non-Hispanic Black [6.7%], and 324 non-Hispanic Asian [5.8%]) were included in the final analysis. Overall, 2060 participants (37.1%) reported delayed testing and 3491 (62.9%) reported early testing. Compared with non-Hispanic White HCP, delayed testing was higher among non-Hispanic Black HCP (adjusted risk ratio, 1.18; 95%CI, 1.10-1.27) and for non-Hispanic HCP of other races (adjusted risk ratio, 1.17; 95% CI, 1.03-1.33). Sex and age were not associated with delayed testing. Compared with clinical HCP with graduate degrees, all other professional and educational groups had significantly delayed testing. Conclusions and Relevance: In this cross-sectional study of HCP, compared with non-Hispanic White HCP and clinical HCP with graduate degrees, non-Hispanic Black HCP, non-Hispanic HCP of other races, and HCP all other professional and education backgrounds were more likely to have delayed COVID-19 testing. These findings suggest that time to testing may serve as a valuable metric in evaluating sociodemographic disparities in the response to COVID-19 and future health mitigation strategies.

This study describes the prevalence of blood transfusion protocols in ICUs caring for neurologically vs. non-neurologically injured patients across a sample of US ICUs. This prospective, observational multi-center cohort study is a subgroup analysis of the USCIITG-CIOS, comprising 69 ICUs across the US (25 medical, 24 surgical, 20 mixed ICUs). Sixty-four ICUs were in teaching hospitals. A total of 6179 patients were enrolled, with 1266 (20.4%) having central nervous system (CNS) primary diagnoses. We evaluated whether CNS versus non-CNS diagnosis was associated with care in ICUs with restrictive transfusion protocols (RTPs) or massive transfusion protocols (MTPs) and whether CNS versus non-CNS diagnosis was associated with receiving blood products or colloids during the initial 24 h of care. Protocol utilization in CNS vs. non-CNS patients was as follows: RTPs-36.9% vs. 42.9% (p < 0.001); MTPs-48.3% vs. 47.4% (p = 0.57). Blood product transfusions in the first 24 h of ICU care (comparing CNS vs. non-CNS patients) were as follows: packed red blood cells-4.3% vs. 14.6% (p < 0.001); fresh frozen plasma-2.9% vs. 5.1% (p < 0.001); colloid blood products-3.2% vs. 9.2% (p < 0.001). In this cohort, we found differences in ICU utilization of RTPs, but not MTPs, when comparing where critically ill patients with neurologic versus non-neurologic primary diagnoses received ICU care.
RESUMO
BACKGROUND: An early acute marker of long-term neurological outcome would be useful to help guide clinical decision making and therapeutic effectiveness after severe traumatic brain injury (TBI). We investigated the utility of the Disability Rating Scale (DRS) as early as 1 wk after TBI as a predictor of favorable 6-mo Glasgow Outcome Scale extended (GOS-E). OBJECTIVE: To determine the predictability of a favorable 6-mo GOS-E using the DRS measured during weeks 1 to 4 of injury. METHODS: The study is a sub analysis of patients enrolled in the Epo Severe TBI Trial (n = 200) to train and validate L1-regularized logistic regression models. DRS was collected at weeks 1 to 4 and GOS-E at 6 mo. RESULTS: The average area under the receiver operating characteristic curve was 0.82 for the model with baseline demographic and injury severity variables and week 1 DRS and increased to 0.88 when including weekly DRS until week 4. CONCLUSION: This study suggests that week 1 to 4 DRS may be predictors of favorable 6-mo outcome in severe TBI patients and thus useful both for clinical prognostication as well as surrogate endpoints for adaptive clinical trials.

BACKGROUND: Research regarding disparities in physical restraint use in the emergency department (ED) is limited. We evaluated the role of race, ethnicity, and preferred language on the application of physical restraint among ED patients held under a Massachusetts section 12(a) order for mandatory psychiatric evaluation. METHODS: We identified all ED patient encounters with a section 12(a) order across a large integrated 11-hospital health system from January 2018 through December 2019. Information on age, race, ethnicity, preferred language, insurance, mental illness, substance use, history of homelessness, and in-network primary care provider was obtained from the electronic health record. We evaluated for differences in physical restraint use between subgroups via a mixed-effect logistic regression with random-intercept model. RESULTS: We identified 32,054 encounters involving a section 12(a) order. Physical restraints were used in 2,458 (7.7%) encounters. Factors associated with physical restraint included male sex (adjusted odds ratio [aOR] = 1.44, 95% confidence interval [CI] = 1.28 to 1.63), Black/African American race (aOR = 1.22, 95% CI = 1.01 to 1.48), Hispanic ethnicity (aOR = 1.45, 95% CI = 1.22 to 1.73), Medicaid insurance (aOR = 1.21, 95% CI = 1.05 to 1.39), and a diagnosis of bipolar disorder or psychotic disorder (aOR = 1.51, 95% CI = 1.31 to 1.74). Across all age groups, patients who were 25 to 34 years of age were at highest risk of restraint (aOR = 2.01, 95% CI = 1.69 to 2.39). Patients with a primary care provider within our network (aOR = 0.81, 95% CI = 0.72 to 0.92) were at lower risk of restraint. No associations were found between restraint use and language, history of alcohol or substance use, or homelessness. CONCLUSION: Black/African American and Hispanic patients under an involuntary mandatory emergency psychiatric evaluation hold order experience higher rates of physical restraint in the ED. Factors contributing to racial disparities in the use of physical restraint, including the potential role of structural racism and other forms of bias, merits further investigation.

STUDY OBJECTIVE: Patients with sickle cell disease often receive a substantial amount of their health care in the emergency department (ED) and some come to the ED frequently, seeking treatment for pain. As a result, patients with sickle cell disease are often stigmatized as opioid-seeking ED overutilizers. We describe the proportion of sickle cell disease patients who are high utilizers of the ED and compare them with other sickle cell disease patients on demographics, pain characteristics, health data, psychosocial characteristics, and quality of life. METHODS: Two hundred thirty-two patients completed baseline data and at least 30 days of daily diary data. Baseline data included demographics, health data, and quality of life (Medical Outcome Study 36 Item Short Form). Daily diary data included ED utilization for sickle cell pain and descriptors of pain and distress. RESULTS: Eighty-two (35.5%) patients were found to be high ED utilizers. Clinically important and statistically significant differences were found between high ED utilizers and all other sickle cell disease patients: lower hematocrit level, more transfusions, more pain days, more pain crises, higher mean pain and distress, and worse quality of life on Medical Outcome Study 36 Item Short Form physical function summary scales. After controlling for severity and frequency of pain, high ED utilizers did not use opioids more frequently than other sickle cell disease patients. CONCLUSION: A substantial minority of sickle cell disease patients are high ED utilizers. However, high ED utilizers with sickle cell disease are more severely ill as measured by laboratory variables, have more pain, more distress, and have a lower quality of life.

BACKGROUND: Researchers of sickle cell disease have traditionally used health care utilization as a proxy for pain and underlying vaso-occlusion. However, utilization may not completely reflect the amount of self-reported pain or acute, painful episodes (crises). OBJECTIVE: To examine the prevalence of self-reported pain and the relationship among pain, crises, and utilization in adults with sickle cell disease. DESIGN: Prospective cohort study. SETTING: Academic and community practices in Virginia. PATIENTS: 232 patients age 16 years or older with sickle cell disease. MEASUREMENTS: Patients completed a daily diary for up to 6 months, recording their maximum pain (on a scale of 0 to 9); whether they were in a crisis (crisis day); and whether they used hospital, emergency, or unscheduled ambulatory care for pain on the previous day (utilization day). Summary measures included both simple proportions and adjusted probabilities (for repeated measures within patients) of pain days, crisis days, and utilization days, as well as mean pain intensity. RESULTS: Pain (with or without crisis or utilization of care) was reported on 54.5% of 31 017 analyzed patient-days (adjusted probability, 56%). Crises without utilization were reported on 12.7% of days and utilization on only 3.5% (unadjusted). In total, 29.3% of patients reported pain in greater than 95% of diary days, whereas only 14.2% reported pain in 5% or fewer diary days (adjusted). The frequency of home opiate use varied and independently predicted pain, crises, and utilization. Mean pain intensity on crisis days, noncrisis pain days, and total pain days increased as the percentage of pain days increased (P < 0.001). Intensity was significantly higher on utilization days (P < 0.001). However, utilization was not an independent predictor of crisis, after controlling for pain intensity. LIMITATIONS: The study was done in a single state. Patients did not always send in their diaries. CONCLUSION: Pain in adults with sickle cell disease is the rule rather than the exception and is far more prevalent and severe than previous large-scale studies have portrayed. It is mostly managed at home; therefore, its prevalence is probably underestimated by health care providers, resulting in misclassification, distorted communication, and undertreatment.

The original unstructured Glasgow Outcome Scale (uGOS) and the newer structured interviews GOS and the Extended GOS (GOS-E) have been used widely as outcomes in severe traumatic brain injury (TBI) trials. We compared outcome categories (ranging from dead [D] to good recovery [GR]) for each measure in a randomized trial of transfusion threshold and the implications of measure choice and analysis methods for the results of the trial. We planned to explore patient symptomology possibly driving any discrepancies between the patient's uGOS and GOS scores. Category correspondence between uGOS and GOS scores occurred in 160 (88.4%) of the 181 analyzed cases. The GOS-E and GOS instruments incorporated more behavioral/cognitive/social and other components, leading to a worse outcome in some cases than for the uGOS. Choice of outcome measure and analysis led to incongruous conclusions. Dichotomizing uGOS into favorable outcome (GR and moderate disability [MD] categories) versus unfavorable (severe disability [SD], vegetative state [VS], and D categories), we observed a significant effect of transfusion threshold (odds ratio [OR] = 0.51, p = 0.03; adjusted OR = 0.40, p = 0.02). For the same dichotomization of GOS and GOS-E, the effect was not statistically significant but the ORs were similar (ORs between 0.57 and 0.68, p > 0.15 for all). An effect was not detected using ordinal logistic regression or sliding dichotomy method for all three measures. Differences in categorizations of subjects between moderate and severe disability among the scales impacted conclusions of the trial. In future studies, particular attention should be given to implementing GOS measures and describing the methodology for how outcomes were ascertained.

OBJECTIVE: Traumatic brain injury (TBI) is a major cause of morbidity and mortality. Multiple organ dysfunction syndrome (MODS) occurs frequently after TBI and independently worsens outcome. The present study aimed to identify potential admission characteristics associated with post-TBI MODS. METHODS: The authors performed a secondary analysis of a recent randomized clinical trial studying the effects of erythropoietin and blood transfusion threshold on neurological recovery after TBI. Admission clinical, demographic, laboratory, and imaging parameters were used in a multivariable Cox regression analysis to identify independent risk factors for MODS following TBI, defined as maximum total Sequential Organ Failure Assessment (SOFA) score > 7 within 10 days of TBI. RESULTS: Two hundred patients were initially recruited and 166 were included in the final analysis. Respiratory dysfunction was the most common nonneurological organ system dysfunction, occurring in 62% of the patients. International Mission for Prognosis and Analysis of Clinical Trials (IMPACT) probability of poor outcome at admission was significantly associated with MODS following TBI (odds ratio [OR] 8.88, 95% confidence interval [CI] 1.94-42.68, p < 0.05). However, more commonly used measures of TBI severity, such as the Glasgow Coma Scale, Injury Severity Scale, and Marshall classification, were not associated with post-TBI MODS. In addition, initial plasma concentrations of interleukin (IL)-6, IL-8, and IL-10 were significantly associated with the development of MODS (OR 1.47, 95% CI 1.20-1.80, p < 0.001 for IL-6; OR 1.26, 95% CI 1.01-1.58, p = 0.042 for IL-8; OR 1.77, 95% CI 1.24-2.53, p = 0.002 for IL-10) as well as individual organ dysfunction (SOFA component score ≥ 1). Finally, MODS following TBI was significantly associated with mortality (OR 5.95, 95% CI 2.18-19.14, p = 0.001), and SOFA score was significantly associated with poor outcome at 6 months (Glasgow Outcome Scale score < 4) when analyzed as a continuous variable (OR 1.21, 95% CI 1.06-1.40, p = 0.006). CONCLUSIONS: Admission IMPACT probability of poor outcome and initial plasma concentrations of IL-6, IL-8, and IL-10 were associated with MODS following TBI.

OBJECTIVE: Depression and anxiety are common in sickle cell disease (SCD) but relatively little is known about their impact on SCD adults. This study measured prevalence of depression and anxiety in SCD adults, and their effects on crisis and noncrisis pain, quality-of-life, opioid usage, and healthcare utilization. METHODS: The Pain in Sickle Cell Epidemiology Study is a prospective cohort study in 308 SCD adults. Baseline variables included demographics, genotype, laboratory data, health-related quality-of-life, depression, and anxiety. Subjects completed daily diaries for up to 6 months, reporting sickle cell pain intensity, distress, interference, whether they were in a sickle cell crisis, as well as health care and opioid utilization. RESULTS: Two hundred thirty-two subjects who completed at least 1 month of diaries were studied; 27.6% were depressed and 6.5% had any anxiety disorder. Depressed subjects had pain on significantly more days than nondepressed subjects (mean pain days 71.1% versus 49.6%, p < .001). When in pain on noncrisis days, depressed subjects had higher mean pain, distress from pain, and interference from pain. Both depressed and anxious subjects had poorer functioning on all eight SF-36 subscales, even after controlling for demographics, hemoglobin type, and pain. The anxious subjects had more pain, distress from pain, and interference from pain, both on noncrisis pain days and on crisis days, and used opioids more often. CONCLUSIONS: Depression and anxiety predicted more daily pain and poorer physical and mental quality-of-life in adults with SCD, and accounted for more of the variance in all domains of quality-of-life than hemoglobin type.

BACKGROUND: This retrospective study evaluated the use of a smartphone application to facilitate communication between the emergency physician (EP) and the interventional cardiologist in order to minimize the time to cardiac catheterization laboratory (CCL) activation and time to percutaneous coronary intervention (PCI). METHODS: We retrospectively collected pertinent time-points in the management of patients diagnosed with STEMI in the emergency department and their outcome. The primary outcome was the reduction in the time from ECG interpretation to CCL activation after the implementation of a smartphone application. A total of 84 patients were enrolled. Patients' electrocardiography (ECG) were described by traditional verbal communication via telephone (group 1, n = 40) and by additional smartphone transmission of ECG images to an interventional cardiologist (group 2, n = 44). Relevant time-points were recorded for analysis. RESULTS: The time from ECG interpretation to CCL activation was reduced from 28.3 ± 4.1 in group 1 to 17.6 ± 2.3 min in group 2 (p = 0.03). Similarly, the time from ECG interpretation to balloon inflation time (D2B) decreased from 93.1 to 73.4 min (p = 0.025). Comparing group 2 with group 1, the door to balloon (D2B) time improved to 90.4 ± 9.8 from 119.3 ± 16.3 min (p = 0.23), the proportion of patients with a D2B time less than 90 min increased to 70.5% from 52.5% (p = 0.09), and the mortality rate decreased to 2.2% from 12.5% (p = 0.07). CONCLUSION: The additional use of a smartphone application to transmit ECG information to interventional cardiologists by EPs facilitated communication and reduced the decision time to CCL activation and percutaneous intervention.

BACKGROUND: We sought to determine the outcome of suicidal hanging and the impact of targeted temperature management (TTM) on hanging-induced cardiac arrest (CA) through an Eastern Association for the Surgery of Trauma (EAST) multicenter retrospective study. METHODS: We analyzed hanging patient data and TTM variables from January 1992 to December 2015. Cerebral performance category score of 1 or 2 was considered good neurologic outcome, while cerebral performance category score of 3 or 4 was considered poor outcome. Classification and Regression Trees recursive partitioning was used to develop multivariate predictive models for survival and neurologic outcome. RESULTS: A total of 692 hanging patients from 17 centers were analyzed for this study. Their overall survival rate was 77%, and the CA survival rate was 28.6%. The CA patients had significantly higher severity of illness and worse outcome than the non-CA patients. Of the 175 CA patients who survived to hospital admission, 81 patients (46.3%) received post-CA TTM. The unadjusted survival of TTM CA patients (24.7% vs 39.4%, p < 0.05) and good neurologic outcome (19.8% vs 37.2%, p < 0.05) were worse than non-TTM CA patients. However, when subgroup analyses were performed between those with an admission Glasgow Coma Scale score of 3 to 8, the differences between TTM and non-TTM CA survival (23.8% vs 30.0%, p = 0.37) and good neurologic outcome (18.8% vs 28.7%, p = 0.14) were not significant. Targeted temperature management implementation and post-CA management varied between the participating centers. Classification and Regression Trees models identified variables predictive of favorable and poor outcome for hanging and TTM patients with excellent accuracy. CONCLUSION: Cardiac arrest hanging patients had worse outcome than non-CA patients. Targeted temperature management CA patients had worse unadjusted survival and neurologic outcome than non-TTM patients. These findings may be explained by their higher severity of illness, variable TTM implementation, and differences in post-CA management. Future prospective studies are necessary to ascertain the effect of TTM on hanging outcome and to validate our Classification and Regression Trees models. LEVEL OF EVIDENCE: Therapeutic study, level IV; prognostic study, level III.

BACKGROUND: Sickle cell disease (SCD) patients can receive their ambulatory care from either SCD specialists (caregivers with sickle cell-only clinics) or nonspecialized care centers. Patient satisfaction, an important factor that may influence compliance and outcome, can differ between the two groups because of the perceived quality of care, outcomes or practice style. METHODS: We administered a patient satisfaction survey to 308 participants in an SCD prospective cohort study. Of the 308 patients, 133 (43.2%) received the majority of their SCD care at specialized centers, 152 (49.3%) received their care from nonspecialized centers and 26 (7.5) did not provide information. The satisfaction surveys measured general satisfaction (GS), technical quality (TQ), interpersonal manner (IM), communication (CM), financial aspects (FA), time spent with doctor (TA), and accessibility and convenience (AC). Patients reported their levels of satisfaction using a five-point Likert scale. We compared unadjusted group means, as well as means adjusted for potential confounders such as marital status, on patient satisfaction between specialized and nonspecialized centers. RESULTS: SCD patients who received their care from specialized centers had significantly higher mean satisfaction scores, compared to those who received their care from nonspecialized centers: GS 4.00(+/-0.93) vs. 3.66 (+/- 01.16, p=0.0326), TQ 3.98 (+/- 0.77) vs. 3.65 (+/- 0.91, p=0.0058), AC 3.83 (+/-0.79) vs. 3.51 (+/- 1.02, p=0.0142) , FA 3.88 (+/-0.96) vs. 3.49 (+/-1.25, p=0.0120). There were no statistically significant group differences in IM, TA and CM. CONCLUSION: SCD patients who received most of their SCD care from specialized centers had somewhat higher satisfaction scores in some areas when compared with patients who received their care from nonspecialized centers.

BACKGROUND: Sepsis is a major risk factor for acute respiratory distress syndrome (ARDS). However, there remains a paucity of literature examining risk factors for ARDS in septic patients early in their course. This study examined the role of early fluid administration and identified other risk factors within the first 6 h of hospital presentation associated with developing ARDS in septic patients. METHODS: This was a secondary analysis of septic adult patients presenting to the Emergency Department or being admitted for high-risk elective surgery from the multicenter observational cohort study, US Critical Injury and Illness trial Group-Lung Injury Prevention Study 1 (USCIITG-LIPS 1, NCT00889772). Multivariable logistic regression was performed to identify potential early risk factors for ARDS. Stratified analysis by shock status was performed to examine the association between early fluid administration and ARDS. RESULTS: Of the 5584 patients in the original study cohort, 2534 (45.4%) met our criteria for sepsis. One hundred and fifty-six (6.2%) of these patients developed ARDS during the hospital stay. In multivariable analyses, Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR 1.10, 95% CI 1.07-1.13), age (OR 0.97, 95% CI 0.96-0.98), total fluid infused in the first 6 h (in liters) (OR 1.15, 95% CI 1.03-1.29), shock (OR 2.57, 95% CI 1.62-4.08), pneumonia as a site of infection (OR 2.31, 95% CI 1.59-3.36), pancreatitis (OR 3.86, 95% CI 1.33-11.24), and acute abdomen (OR 3.77, 95% CI 1.37-10.41) were associated with developing ARDS. In the stratified analysis, total fluid infused in the first 6 h (in liters) (OR 1.05, 95% CI 0.87-1.28) was not associated with the development of ARDS in the shock group, while there was an association in the non-shock group (OR 1.21, 95% CI 1.05-1.38). CONCLUSIONS: In septic patients, the following risk factors identified within the first 6 h of hospital presentation were associated with ARDS: APACHE II score, presence of shock, pulmonary source of infection, pancreatitis, and presence of an acute abdomen. In septic patients without shock, the amount of fluid infused during the first 6 h of hospital presentation was associated with developing ARDS.
RESUMO
Background. Patients with SCD now usually live well into adulthood. Whereas transitions into adulthood are now often studied, little is published about aging beyond the transition period. We therefore studied age-associated SCD differences in utilization, pain, and psychosocial variables. Methods. Subjects were 232 adults in the Pain in Sickle Cell Epidemiology Study (PiSCES). Data included demographics, comorbidity, and psychosocial measures. SCD-related pain and health care utilization were recorded in diaries. We compared 3 age groups: 16-25 (transition), 26-36 (younger adults), and 37-64 (older adults) years. Results. Compared to the 2 adult groups, the transition group reported fewer physical challenges via comorbidities, somatic complaints, and pain frequency, though pain intensity did not differ on crisis or noncrisis pain days. The transition group utilized opioids less often, made fewer ambulatory visits, and had better quality of life, but these differences disappeared after adjusting for pain and comorbidities. However, the transition group reported more use of behavioral coping strategies. Conclusion. We found fewer biological challenges, visits, and better quality of life, in transition-aged versus older adults with SCD, but more behavioral coping. Further study is required to determine whether age-appropriate health care, behavioral, or other interventions could improve age-specific life challenges of patients with SCD.

BACKGROUND: Although theophylline has been shown to have anti-inflammatory effects, the therapeutic use of theophylline before sepsis is unknown. The aim of our study was to determine the effect of theophylline on COPD patients presenting with sepsis. METHODS: This nationwide, population-based, propensity score-matched analysis used data from the linked administrative databases of Taiwan's National Health Insurance program. Patients with COPD who were hospitalized for sepsis between 2000 and 2011 were divided into theophylline users and non-users. The primary outcome was 30-day mortality. The secondary outcome was in-hospital death, intensive care unit admission, and need for mechanical ventilation. Cox proportional hazard model and conditional logistic regression were used to calculate the risk between groups. RESULTS: A propensity score-matched cohort of 51,801 theophylline users and 51,801 non-users was included. Compared with non-users, the 30-day (HR 0.931, 95% CI 0.910-0.953), 180-day (HR 0.930, 95% CI 0.914-0.946), 365-day (HR 0.944, 95% CI 0.929-0.960) and overall mortality (HR 0.965, 95% CI 0.952-0.979) were all significantly lower in theophylline users. Additionally, the theophylline users also had lower risk of in-hospital death (OR 0.895, 95% CI 0.873-0.918) and need for mechanical ventilation (OR 0.972, 95% CI 0.949-0.997). CONCLUSIONS: Theophylline use is associated with a lower risk of sepsis-related mortality in COPD patients. Pre-hospital theophylline use may be protective to COPD patients with sepsis.
