RESUMO
BACKGROUND: It is unknown which factors are associated with chest radiograph (CXR) and antibiotic use for suspected community-acquired pneumonia (CAP) in children. We evaluated factors associated with CXR and antibiotic preferences among clinicians for children with suspected CAP using case scenarios generated through artificial intelligence (AI). METHODS: We performed a survey of general pediatric, pediatric emergency medicine, and emergency medicine attending physicians employed by a private physician contractor. Respondents were given 5 unique, AI-generated case scenarios. We used generalized estimating equations to identify factors associated with CXR and antibiotic use. We evaluated the cluster-weighted correlation between clinician suspicion and clinical prediction model risk estimates for CAP using 2 predictive models. RESULTS: A total of 172 respondents provided responses to 839 scenarios. Factors associated with CXR acquisition (OR, [95% CI]) included presence of crackles (4.17 [2.19, 7.95]), prior pneumonia (2.38 [1.32, 4.20]), chest pain (1.90 [1.18, 3.05]) and fever (1.82 [1.32, 2.52]). The decision to use antibiotics before knowledge of CXR results included past hospitalization for pneumonia (4.24 [1.88, 9.57]), focal decreased breath sounds (3.86 [1.98, 7.52]), and crackles (3.45 [2.15, 5.53]). After revealing CXR results to clinicians, these results were the sole predictor associated with antibiotic decision-making. Suspicion for CAP correlated with one of 2 prediction models for CAP (Spearman's rho = 0.25). Factors associated with a greater suspicion of pneumonia included prior pneumonia, duration of illness, worsening course of illness, shortness of breath, vomiting, decreased oral intake or urinary output, respiratory distress, head nodding, focal decreased breath sounds, focal rhonchi, fever, and crackles, and lower pulse oximetry. CONCLUSIONS: Ordering preferences for CXRs demonstrated similarities and differences with evidence-based risk models for CAP. Clinicians relied heavily on CXR findings to guide antibiotic ordering. These findings can be used within decision support systems to promote evidence-based management practices for pediatric CAP.
RESUMO
BACKGROUND: Constipation is a common diagnosis in adults and children. Emergency department (ED) visits for constipation increased from 1980 to 2010. Since then, efforts have aimed to reduce resource utilization for constipation in the ED setting. Our objective is to examine contemporary ED practice patterns in the context of updated care guidelines. METHODS: We conducted a cross-sectional study using the National Hospital Ambulatory Medical Care Survey from 2006 to 2017. Encounters with a constipation diagnosis were included. We examined rates of ED visits, diagnostic testing, and medication use. We also compared general and pediatric ED practice patterns for children. RESULTS: Approximately 1.3 million ED visits with a diagnosis of constipation occurred annually, with pediatric encounters comprising one-third of all visits. There was a 114% increase in ED visits for constipation over the study period. Urinalysis and imaging increased by 17% and 15%, respectively. Older patients were more likely to undergo diagnostic testing. No significant changes in laboratory testing, radiographs, or osmotic laxative prescriptions were observed among children. Compared to pediatric EDs, general EDs were more likely to perform CBC (29% vs. 15%) and urinalysis testing (42% vs 31%). General EDs were less likely to prescribe osmotic laxatives for children compared to pediatric EDs (26% vs. 37%). CONCLUSION: ED visits for constipation have increased significantly since 2006. Rates of diagnostic tests and prescriptions have not changed despite published evidence and guidelines that the diagnosis of constipation does not require imaging, and that the management of constipation requires consistent outpatient treatment. Opportunities exist to reduce ED resource utilization through knowledge dissemination and implementation.

BACKGROUND: Procedural sedation (PS) is commonly performed in emergency departments (EDs) by nonanesthesiologists. Although adverse events (AEs) are rare, providers must possess the clinical skills to react in a timely manner. We previously described residents' experience and confidence in PS as part of a needs assessment. We found that their ability to perform important clinical tasks as a result of the usual training experience demonstrates educational needs. We developed an educational intervention to address the deficiencies uncovered during our needs assessment. OBJECTIVE: To evaluate the effectiveness of an educational intervention on pediatric residents' clinical performance and confidence when faced with an AE during a simulated PS. METHODS: This was a prospective observational cohort study of residents at a tertiary care children's hospital. All ED attending physicians and fellows were trained in uniform delivery of the educational intervention, which was delivered extemporaneously at the bedside ("Just-in-Time" [JIT]) to all residents performing PS on actual patients in the pediatric ED, over the course of 1 year. Subjects completed the following both before and after the educational intervention: a survey pertaining to confidence in PS, followed by a standardized, video-recorded simulated PS complicated by apnea and desaturation. Clinical performance was evaluated and assessed both in real time and by a video-rater blinded to participants' year of training. We summarized baseline resident characteristics, confidence questionnaire item rankings and success in both the preparation and AE tasks. We compared successful task completion and time to task completion before and after intervention. RESULTS: Forty residents completed both the PRE and POST phases of the study. There was significant improvement in the proportion of residents who completed both preparation and AE tasks after the JIT training. Specifically, there was a significant improvement in the proportion of residents who performed positive-pressure ventilation to treat an apneic event associated with desaturation during the PS (P = 0.007). Residents' confidence scores also significantly improved after the training. CONCLUSION: A brief JIT training in the pediatric ED improves resident clinical performance and confidence when faced with an AE during a simulated PS. Future direction includes correlating this improved performance with patient outcomes in PS.

BACKGROUND: Although community-acquired pneumonia (CAP) is one of the most common infections in children, no tools exist to risk stratify children with suspected CAP. We developed and validated a prediction model to risk stratify and inform hospitalization decisions in children with suspected CAP. METHODS: We performed a prospective cohort study of children aged 3 months to 18 years with suspected CAP in a pediatric emergency department. Primary outcome was disease severity, defined as mild (discharge home or hospitalization for <24 hours with no oxygen or intravenous [IV] fluids), moderate (hospitalization <24 hours with oxygen or IV fluids, or hospitalization >24 hours), or severe (intensive care unit stay for >24 hours, septic shock, vasoactive agents, positive-pressure ventilation, chest drainage, extracorporeal membrane oxygenation, or death). Ordinal logistic regression and bootstrapped backwards selection were used to derive and internally validate our model. RESULTS: Of 1128 children, 371 (32.9%) developed moderate disease and 48 (4.3%) severe disease. Severity models demonstrated excellent discrimination (optimism-corrected c-indices of 0.81) and outstanding calibration. Severity predictors in the final model included respiratory rate, systolic blood pressure, oxygenation, retractions, capillary refill, atelectasis or pneumonia on chest radiograph, and pleural effusion. CONCLUSIONS: We derived and internally validated a score that accurately predicts disease severity in children with suspected CAP. Once externally validated, this score has potential to facilitate management decisions by providing individualized risk estimates that can be used in conjunction with clinical judgment to improve the care of children with suspected CAP.

OBJECTIVES: Sexual trauma poses a significant concern and is associated with heightened stress, negative health repercussions, and adverse economic effects. A history of abuse may increase a woman's risk of developing cancer, in particular cervical cancer. We analyzed the impact of screening for sexual abuse in a gynecologic oncology population. METHODS: Patients were screened for sexual trauma in a gynecologic oncology clinic over 5 and a half years (April 1, 2011, to September 30, 2016) in this cohort study. The screening questions were selected by behavioral oncology physicians and integrated into the gynecologic history component of the new patient assessment. Patients who screened positive for a history of sexual abuse or intimate partner violence were offered a behavioral oncology referral. Providers were also questioned about the effect of screening on their practice. RESULTS: Of the 1,423 consecutive patients screened for sexual trauma, a total of 164 patients (12%) disclosed a history of sexual abuse. Of the 133 patients who specified their age at the sexual trauma, the majority (107 [80%]) responded that they were a young child or early teen. Most patients (92%) declined counseling. Among individuals presenting with cancer, the distribution of cancer type was statistically different between those patients with and without a sexual trauma history (p = 0.0001). CONCLUSION: Screening for sexual trauma in a gynecologic oncologic population serves as a valuable opportunity to uncover a history of abuse that may increase a woman's susceptibility to cancer. This study demonstrates that screening for sexual abuse in a gynecologic oncology setting may be integrated into new patient interviews with minimal disruption. Identification of an undisclosed sexual trauma history allows for an opportunity to offer counseling and minimize the emotional distress that may be precipitated by treatment and exams.

OBJECTIVE: To compare caregiver features and caregiving arrangements of children with physical abuse vs accidental injuries. STUDY DESIGN: Data came from a prospective, observational, multicenter study investigating bruising and psychosocial characteristics of children younger than 4 years of age. Using logistic regression, we examined how abuse vs accidental injury and severity of injury were associated with caregiver sex, relation to the child, whether caregiving arrangements were different than usual at the time of injury, and length of the main caregiver's relationship with his/her partner. RESULTS: Of 1615 patients, 24% were determined to have been physically abused. Abuse was more likely when a male caregiver was present (OR 3.31, 95% CI 2.38-4.62). When the male was the boyfriend of the mother (or another female caregiver), the odds of abuse were very high (OR 169.2, 95% CI 61.3-614.0). Severe or fatal injuries also were more likely when a male caregiver was present. In contrast, abuse was substantially less likely when a female caregiver was present (OR 0.25, 95% CI 0.17-0.37) with the exception of a female babysitter (OR 3.87, 95% CI 2.15-7.01). Caregiving arrangements that were different than usual and caregiver relationships <1 year were also associated with an increased risk of abuse. CONCLUSIONS: We identified caregiver features associated with physical abuse. In clinical practice, questions regarding caregiver features may improve recognition of the abused child. This information may also inform future abuse prevention strategies.

BACKGROUND: While warfarin is the most commonly prescribed medication to prevent thromboembolic disorders, the risk of adverse drug reactions (ADR) poses a serious concern. This prospective study evaluated how primary care providers (PCP) and cardiologists at our Institution managed patients treated with warfarin with the goal of decreasing the number of warfarin ADRs. METHODS: A multidisciplinary anticoagulation task force was established at our Institution in 2014 to standardize warfarin monitoring and management. Between 2013 and 2017, we analyzed patients who were prescribed warfarin by their PCP or cardiologist upon hospital discharge and in the ambulatory setting to determine the international normalized ratio (INR) within 5, 10, and 30 days after discharge, time in therapeutic range (TTR), number of severe warfarin ADRs, and total and average cost reduction of all severe warfarin ADRs to determine whether there was an organizational cost savings following the implementation of standardized warfarin care. RESULTS: The warfarin ADR rate significantly decreased over the 5-year period, from 3.8 to 0.98% (p < 0.0001). The proportion of warfarin prescriptions out of all anticoagulants significantly decreased, from 72.2 to 42.1% (p < 0.001). The proportion of individuals who received an INR at 5, 10, and 30 days after hospital discharge compared to the total number of patients prescribed warfarin significantly increased (p < 0.001). The total cost of severe warfarin ADRs decreased by 57.6% between 2013 and 2017. CONCLUSIONS: This study serves as a model to reduce the number of severe warfarin ADRs by the following tactics: (1) educating PCPs and cardiologists about evidence-based guidelines for warfarin management, (2) increasing the use of our Institution's electronic warfarin module, and (3) enhancing patient compliance with obtaining INR.

OBJECTIVE: To assess interrater reliability and accuracy of an expert panel in classifying injuries of patients as abusive or accidental based on comprehensive case information. STUDY DESIGN: Data came from a prospective, observational, multicenter study investigating bruising characteristics of children younger than 4 years. We enrolled 2166 patients with broad ranges of illnesses and injuries presenting to one of 5 pediatric emergency departments in whom bruises were identified during examination. We collected comprehensive data regarding current and past injuries and illnesses, and provided deidentified, standardized case information to a 9-member multidisciplinary panel of experts with extensive experience in pediatric injury. Each panelist classified cases using a 5-level ordinal scale ranging from definite abuse to definite accident. Panelists also assessed whether report to child protective services (CPS) was warranted. We calculated reliability coefficients for likelihood of abuse and decision to report to CPS. RESULTS: The interrater reliability of the panelists was high. The Kendall coefficient (95% CI) for the likelihood of abuse was 0.89 (0.87, 0.91) and the kappa coefficient for the decision to report to CPS was 0.91 (0.87, 0.94). Reliability of pairs and subgroups of panelists were similarly high. A panel composite classification was nearly perfectly accurate in a subset of cases having definitive, corroborated injury status. CONCLUSIONS: A panel of experts with different backgrounds but common expertise in pediatric injury is a reliable and accurate criterion standard for classifying pediatric injuries as abusive or accidental in a sample of children presenting to a pediatric emergency department.

OBJECTIVE: To determine the impact of long-term, body weight-supported locomotor training after chronic, incomplete spinal cord injury (SCI), and to estimate the health care costs related to lost recovery potential and preventable secondary complications that may have occurred because of visit limits imposed by insurers. DESIGN: Prospective observational cohort with longitudinal follow-up. SETTING: Eight outpatient rehabilitation centers that participate in the Christopher & Dana Reeve Foundation NeuroRecovery Network (NRN). PARTICIPANTS: Individuals with motor incomplete chronic SCI (American Spinal Injury Association Impairment Scale C or D; N=69; 0.1-45y after SCI) who completed at least 120 NRN physical therapy sessions. INTERVENTIONS: Manually assisted locomotor training (LT) in a body weight-supported treadmill environment, overground standing and stepping activities, and community integration tasks. MAIN OUTCOME MEASURES: International Standards for Neurological Classification of Spinal Cord Injury motor and sensory scores, orthostatic hypotension, bowel/bladder/sexual function, Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI), Berg Balance Scale, Modified Functional Reach, 10-m walk test, and 6-minute walk test. Longitudinal outcome measure collection occurred every 20 treatments and at 6- to 12-month follow-up after discharge from therapy. RESULTS: Significant improvement occurred for upper and lower motor strength, functional activities, psychological arousal, sensation of bowel movement, and SCI-FAI community ambulation. Extended training enabled minimal detectable changes at 60, 80, 100, and 120 sessions. After detectable change occurred, it was sustained through 120 sessions and continued 6 to 12 months after treatment. CONCLUSIONS: Delivering at least 120 sessions of LT improves recovery from incomplete chronic SCI. Because walking reduces rehospitalization, LT delivered beyond the average 20-session insurance limit can reduce rehospitalizations and long-term health costs.

Patients with hepatocellular carcinoma (HCC) have been advantaged on the liver transplant waiting list within the United States, and a 6-month delay and exception point cap have recently been implemented to address this disparity. An alternative approach to prioritization is an HCC-specific scoring model such as the MELD Equivalent (MELDEQ ) and the mixed new deMELD. Using data on adult patients added to the UNOS waitlist between 30 September 2009 and 30 June 2014, we compared projected dropout and transplant probabilities for patients with HCC under these two models. Both scores matched actual non-HCC dropout in groups with scores <22 and improved equity with non-HCC transplant probabilities overall. However, neither score matched non-HCC dropout accurately for scores of 25-40 and projected dropout increased beyond non-HCC probabilities for scores <16. The main differences between the two scores were as follows: (i) the MELDEQ assigns 6.85 more points after 6 months on the waitlist and (ii) the deMELD gives greater weight to tumor size and laboratory MELD. Post-transplant survival was lower for patients with scores in the 22-30 range compared with those with scores <16 (P = 0.007, MELDEQ ; P = 0.015, deMELD). While both scores result in better equity of waitlist outcomes compared with scheduled progression, continued development and calibration is recommended.

BACKGROUND: Ketamine is commonly used in the emergency department for short, painful procedures. We describe changes in blood pressure (BP) and heart rate (HR) during procedural sedation with ketamine, as these changes have not been well described in children. METHODS: We performed a secondary analysis of a prospective, observational study involving children aged 8 to 18 years who received procedural sedation with ketamine in a pediatric emergency department. Serial vital signs and sedation scores were recorded from baseline until recovery from ketamine procedural sedation. Time of orthopedic manipulation was also recorded. Linear mixed-effect models were used to evaluate changes in systolic BP (SBP), diastolic BP (DBP), and HR using 3 sedation strata: presedation (baseline), sedated (ketamine administered and patient deeply sedated), and recovery (ketamine administered with patient minimally sedated), controlling for age and weight. RESULTS: Sixty children were enrolled; 10 were excluded due to missing manipulation time. A total of 394 observations were recorded. Mean sedated SBP, DBP, and HR were 8 mm Hg, 4 mm Hg, and 13 beats/min higher than presedation SBP (P<.001), DBP (P<.01), and HR (P<.001), respectively. Mean sedated SBP and DBP were 3 and 4 mm Hg higher than SBP (P=.006) and DBP (P<.01) during recovery. Manipulation increased mean SBP by 5 mm Hg (P<.001), mean DBP by 7 mm Hg (P<.001), and mean HR by 1 beat/min (P=.35). CONCLUSIONS: Ketamine administered during procedural sedation for painful procedures causes a statistically significant but modest increase in SBP, DBP, and HR. Orthopedic manipulation further increases BP.

The United Network for Organ Sharing (UNOS) recently implemented a 6-month delay before granting exception points to liver transplantation candidates with hepatocellular carcinoma (HCC) to address disparity in transplantation access between HCC and non-HCC patients. An HCC-specific scoring scheme, the Model for End-Stage Liver Disease equivalent (MELDEQ ), has also been developed. We compared projected dropout and transplant probabilities and posttransplant survival for HCC and non-HCC patients under the 6-month delay and the MELDEQ using UNOS data from October 1, 2009, to June 30, 2014, and multistate modeling. Overall (combined HCC and non-HCC) wait-list dropout was similar under both schemes and slightly improved (though not statistically significant) compared to actual data. Projected HCC wait-list dropout was similar between the MELDEQ and 6-month delay at 6 months but thereafter started to differ, with the 6-month delay eventually favoring HCC patients (3-year dropout 10.0% [9.0%-11.0%] for HCC versus 14.1% [13.6%-14.6%]) for non-HCC) and the MELDEQ favoring non-HCC patients (3-year dropout 16.0% [13.2%-18.8%] for HCC versus 12.3% [11.9%-12.7%] for non-HCC). Projected transplant probabilities for HCC patients were substantially lower under the MELDEQ compared to the 6-month delay (26.6% versus 83.8% by 3 years, respectively). Projected HCC posttransplant survival under the 6-month delay was similar to actual, but slightly worse under the MELDEQ (2-year survival 82.9% [81.7%-84.2%] versus actual of 85.5% [84.3%-86.7%]). In conclusion, although the 6-month delay improves equity in transplant and dropout between HCC and non-HCC candidates, disparity between the 2 groups may still exist after 6 months of wait-list time. Projections under the MELDEQ , however, appear to disadvantage HCC patients. Therefore, modification to the exception point progression or refinement of an HCC prioritization score may be warranted.

STUDY OBJECTIVE: Bruising can indicate abuse for infants. Bruise prevalence among infants in the pediatric emergency department (ED) setting is unknown. Our objective is to determine prevalence of bruising, associated chief complaints, and frequency of abuse evaluations in previously healthy infants presenting to pediatric EDs. METHODS: We conducted a prospective, observational, multicenter study of infants aged 12 months or younger presenting to pediatric EDs. Structured sampling was used. Pediatric emergency medicine clinicians performed complete skin examinations to screen for bruising. Study investigators documented skin findings, date of visit, patient's age, chief complaint, and abuse evaluation. The primary outcome was prevalence of bruising. Secondary outcomes were prevalence of bruising based on chief complaint and frequency of abuse evaluation. Point estimates of bruise prevalence and differences in bruise prevalence between patient subgroups were calculated with 95% confidence intervals (CIs). RESULTS: Bruising was identified in 88 of 2,488 infants (3.5%; 95% CI 2.9% to 4.4%). Rates of bruising for infants 5 months and younger and older than 5 months were 1.3% and 6.4%, respectively (difference 5.1%; 95% CI 3.6% to 6.8%). For infants 5 months and younger, 83% of bruising was associated with a trauma chief complaint and only 0.2% of infants presenting with a medical chief complaint had bruising. Pediatric emergency medicine clinicians obtained abuse evaluations on 23% of infants with bruising, and that rate increased to 50% for infants 5 months and younger. CONCLUSION: Bruising prevalence in children 12 months and younger who were evaluated in pediatric EDs was low, increased within age strata, and was most often associated with a trauma chief complaint. Most bruised infants did not undergo an abuse evaluation.

STUDY OBJECTIVE: We determine the increase in intraocular pressure during pediatric procedural sedation with ketamine, and the proportion of children whose increase might be clinically important (at least 5 mm Hg). METHODS: We prospectively enrolled children aged 8 to 18 years, chosen to receive ketamine sedation in a pediatric emergency department. We measured intraocular pressure before sedation, immediately after ketamine administration, 2 minutes post-drug administration, and every 5 minutes thereafter until recovery or 30 minutes after the final dose. We descriptively report our observations. RESULTS: For the 60 children enrolled, the median intraocular pressure increase was 3 mm Hg (range 0 to 8 mm Hg). Fifteen children had a brief greater than or equal to 5 mm Hg increase in intraocular pressure from baseline. CONCLUSION: In this study of ketamine sedation in children with healthy eyes, we observed mild increases in intraocular pressure that at times transiently exceeded our bounds for potential clinical importance (5 mm Hg).

OBJECTIVE: To externally validate two prediction models for pediatric radiographic pneumonia. METHODS: We prospectively evaluated the performance of two prediction models (Pneumonia Risk Score [PRS] and CARPE DIEM models) from a prospective convenience sample of children 90 days - 18 years of age from a pediatric emergency department undergoing chest radiography for suspected pneumonia between January 1, 2022, to December 31st, 2023. We evaluated model performance using the original intercepts and coefficients and evaluated for performance changes when performing recalibration and re-estimation procedures. RESULTS: We included 202 patients (median age 3 years, IQR 1-6 years), of whom radiographic pneumonia was found in 92 (41.0%). The PRS model had an area under the receiver operator characteristic curve of 0.72 (95% confidence interval [CI] 0.64-0.79), which was higher than the CARPE DIEM (0.59; 95% CI 0.51-0.67) (P<0.01). Using optimal cutpoints, the PRS model showed higher sensitivity (65.2%, 95% CI 54.6-74.9) and specificity (72.7%, 95% CI 63.4-80.8) compared to the CARPE DIEM model (sensitivity 56.5 [95% CI 45.8-66.8]; specificity 60.9 [95% CI 50.2-69.2]). Recalibration and re-estimation of models improved performance, particularly for the CARPE DIEM model, with gains in sensitivity and specificity, and improved calibration. CONCLUSION: The PRS model demonstrated better performance than the CARPE DIEM model in predicting radiographic pneumonia. Among children with a high rate of pneumonia, these models did not reach a level of performance sufficient to be used independently of clinical judgement. These findings highlight the need for further validation and improvement of models to enhance their utility.
RESUMO
BACKGROUND AND OBJECTIVES: Time to clinical stability (TCS) is a commonly used outcome in adults with community-acquired pneumonia (CAP), yet few studies have evaluated TCS in children. Our objective was to determine the association between TCS and disease severity in children with suspected CAP, as well as factors associated with reaching early stability. METHODS: This is a prospective cohort study of children (aged 3 months to 18 years) hospitalized with suspected CAP. TCS parameters included temperature, heart rate, respiratory rate, and hypoxemia with the use of supplemental oxygen. TCS was defined as time from admission to parameter normalization. The association of TCS with severity and clinical factors associated with earlier TCS were evaluated. RESULTS: Of 571 children, 187 (32.7%) had at least 1 abnormal parameter at discharge, and none had ≥3 abnormal discharge parameters. A greater proportion of infants (90 [93%]) had all 4 parameters stable at discharge compared with 12- to 18-year-old youths (21 [49%]). The median TCS for each parameter was <24 hours. Younger age, absence of vomiting, diffusely decreased breath sounds, and normal capillary refill were associated with earlier TCS. Children who did not reach stability were not more likely to revisit after discharge. CONCLUSIONS: A TCS outcome consisting of physiologic variables may be useful for objectively assessing disease recovery and clinical readiness for discharge among children hospitalized with CAP. TCS may decrease length of stay if implemented to guide discharge decisions. Clinicians can consider factors associated with earlier TCS for management decisions.

BACKGROUND: There is insufficient evidence to guide the initial evaluation of hypothermic infants. We aimed to evaluate risk factors for serious bacterial infections (SBI) among hypothermic infants presenting to the emergency department (ED). METHODS: We conducted a multicenter case-control study among hypothermic (rectal temperature <36.5°C) infants ≤90 days presenting to the ED who had a blood culture collected. Our outcome was SBI (bacteremia, bacterial meningitis, and/or urinary tract infection). We performed 1:2 matching. Historical, physical examination and laboratory covariables were determined based on the literature review from febrile and hypothermic infants and used logistic regression to identify candidate risk factors. RESULTS: Among 934 included infants, 57 (6.1%) had an SBI. In univariable analyses, the following were associated with SBI: age > 21 days, fever at home or in the ED, leukocytosis, elevated absolute neutrophil count, thrombocytosis, and abnormal urinalysis. Prematurity, respiratory distress, and hypothermia at home were negatively associated with SBI. The full multivariable model exhibited a c-index of 0.91 (95% confidence interval: 0.88-0.94). One variable (abnormal urinalysis) was selected for a reduced model, which had a c-index of 0.82 (95% confidence interval: 0.75-0.89). In a sensitivity analysis among hypothermic infants without fever (n = 22 with SBI among 116 infants), leukocytosis, absolute neutrophil count, and abnormal urinalysis were associated with SBI. CONCLUSIONS: Historical, examination, and laboratory data show potential as variables for risk stratification of hypothermic infants with concern for SBI. Larger studies are needed to definitively risk stratify this cohort, particularly for invasive bacterial infections.

BACKGROUND: Invasive cervical carcinoma is preceded by a precancerous phase, cervical intra-epithelial neoplasia (CIN), which can be detected on cervical smears and confirmed by colposcopy and biopsy. Moderate and severe cases of intra-epithelial neoplasia (CIN2 and CIN3) are treated mainly with surgery to prevent progression to invasive carcinoma. Medical methods of preventing the progression or inducing the regression of CIN are needed. Retinoids are potent modulators of epithelial cell growth and differentiation that may have potential for the treatment of CIN. OBJECTIVES: To ascertain whether retinoids can cause regression or prevent progression of CIN. SEARCH METHODS: We searched the Cochrane Gynaecological Cancer Review Group's Specialised Register and Non-Trials Database, the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 3, 2010), and MEDLINE and EMBASE (July 2010).For the 2013 update, the searches were re-run as follows: CENTRAL, Issue 3, 2013; MEDLINE, April, Week 2, 2013; and EMBASE, Week 16, 2013. SELECTION CRITERIA: Randomized controlled trials (RCTs) and non-RCTs of retinoids for treating CIN in women. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data from the trials. Adverse effects information was also collected from the trials. MAIN RESULTS: Five RCTs comparing the efficacy of four different retinoids were identified. Two studies examined the effects on CIN2 and CIN3 of the retinoids N-(4-hydroxyphenyl)retinamide (fenretinide) and 9-cis-retinoic acid (aliretinoin) given orally. Two examined the effect of all-trans-retinoic acid administered topically to the cervix. The fifth study investigated the use of 13-cis-retinoic acid (isotretinoin) given orally to human immunodeficiency virus (HIV)-positive participants with CIN1 and condyloma.Four studies reported no significant effect of retinoids on the progression to higher grades of CIN, and the fifth did not report data on progression. In all studies retinoids had no significant effect on regression of CIN3. Two studies reported that retinoids were associated with regression of CIN2. One reported a greater complete regression of CIN2 over that seen with placebo, which was of borderline statistical significance (odds ratio (OR) 0.5, 95% confidence interval (CI) 0.25 to 1.02). The other study reported a nonsignificant dose-related trend toward increased rates of complete and partial regression compared with placebo. One study reported significantly worse outcomes in women receiving retinoid (OR for regression 6.00, 95% CI 1.00 to 35.91). In general, the retinoid medications were well tolerated.In the 2010 review and in this update, no new studies were identified for inclusion. AUTHORS' CONCLUSIONS: The retinoids studied are not effective in causing regression of CIN3 but may have some effect on CIN2. The data on CIN1 are inadequate. Retinoids are not effective in preventing progression of CIN of any grade. At the doses given for the duration of treatment studied, the retinoids were reasonably well tolerated.

OBJECTIVES: Abusive head trauma is a leading cause of traumatic death and disability during infancy and early childhood. Evidence-based screening tools for abusive head trauma do not exist. Our research objectives were 1) to measure the predictive relationships between abusive head trauma and isolated, discriminating, and reliable clinical variables and 2) to derive a reliable, sensitive, abusive head trauma clinical prediction rule that-if validated-can inform pediatric intensivists' early decisions to launch (or forego) an evaluation for abuse. DESIGN: Prospective, multicenter, cross-sectional, observational. SETTING: Fourteen PICUs. PATIENTS: Acutely head-injured children less than 3 years old admitted for intensive care. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Applying a priori definitional criteria for abusive head trauma, we identified clinical variables that were discriminating and reliable, calculated likelihood ratios and post-test probabilities of abuse, and applied recursive partitioning to derive an abusive head trauma clinical prediction rule with maximum sensitivity-to help rule out abusive head trauma, if negative. Pretest probability (prevalence) of abusive head trauma in our study population was 0.45 (95 of 209). Post-test probabilities of abusive head trauma for isolated, discriminating, and reliable clinical variables ranged from 0.1 to 0.86. Some of these variables, when positive, shifted probability of abuse upward greatly but changed it little when negative. Other variables, when negative, largely excluded abusive head trauma but increased probability of abuse only slightly when positive. Some discriminating variables demonstrated poor inter-rater reliability. A cluster of five discriminating and reliable variables available at or near the time of hospital admission identified 97% of study patients meeting a priori definitional criteria for abusive head trauma. Negative predictive value was 91%. CONCLUSIONS: A more completeunderstanding of the specific predictive qualities of isolated, discriminating, and reliable variables could improve screening accuracy. If validated, a reliable, sensitive, abusive head trauma clinical prediction rule could be used by pediatric intensivists to calculate an evidence-based, patient-specific estimate of abuse probability that can inform-not dictate-their early decisions to launch (or forego) an evaluation for abuse.
