BACKGROUND: While intravenous fluid (IVF) therapy in patients with sickle cell disease (SCD) admitted for a vaso-occlusive episode (VOE) can help reduce red blood cell sickling, clinical practice varies across institutions. We examined the relationship between IVF therapy and hospital length of stay (HLOS), as well as adverse events, such as acute chest syndrome (ACS), pediatric intensive care unit (PICU) transfer, and 28-day re-admission. METHODS: This is a single-center retrospective analysis of SCD VOE hospitalizations between January 2015 and April 2020. Patients with SCD, age 0-30, with consecutive hospitalizations for VOE were included. For the first 3 days of each admission, an "IVF ratio" was calculated by dividing actual IVF rate administered by weight-based maintenance IVF (mIVF) rate. RESULTS: A total of 617 hospitalizations for 161 patients were included. Mean HLOS was 5.7 days, (SD 3.9), and mean IVF volume over the first 3 days of admission was 139.6 mL/kg/day (SD 57.8). Multivariate analysis showed that for each additional 0.5 times the mIVF rate, HLOS increased by 0.53 day (p < .001; 95% confidence interval [CI]: 0.609-0.989), but there was no significant association between IVF therapy and adverse events. History of chronic pain was associated with increased odds of re-admission (OR 6.4; 95% CI: 3.93-10.52). CONCLUSIONS: Despite the theoretical potential for IVF therapy to slow down the sickling process, our findings suggest that increased IVF therapy was associated with prolonged HLOS, which places a burden on patients, families, and the health system.

Introduction: West Nile Virus (WNV) is a zoonotic flavivirus transmitted by mosquitoes. Especially in the elderly or in immunocompromised individuals an infection with WNV can lead to severe neurological symptoms. To date, no human vaccine against WNV is available. The Envelope (E) protein, located at the surface of flaviviruses, is involved in the invasion into host cells and is the major target for neutralizing antibodies and therefore central to vaccine development. Due to their close genetic and structural relationship, flaviviruses share highly conserved epitopes, such as the fusion loop domain (FL) in the E protein, that are recognized by cross-reactive antibodies. These antibodies can lead to enhancement of infection with heterologous flaviviruses, which is a major concern for potential vaccines in areas with co-circulation of different flaviviruses, e.g. Dengue or Zika viruses. Material: To reduce the potential of inducing cross-reactive antibodies, we performed an immunization study in mice using WNV E proteins with either wild type sequence or a mutated FL, and WNV E domain III which does not contain the FL at all. Results and discussion: Our data show that all antigens induce high levels of WNV-binding antibodies. However, the level of protection against WNV varied, with the wildtype E protein inducing full, the other antigens only partial protection. On the other hand, serological cross-reactivity to heterologous flaviviruses was significantly reduced after immunization with the mutated E protein or domain III as compared to the wild type version. These results have indications for choosing antigens with the optimal specificity and efficacy in WNV vaccine development.

Hypoxic ischemic encephalopathy (HIE) is a brain injury that occurs in 1 ~ 5/1000 term neonates. Accurate identification and segmentation of HIE-related lesions in neonatal brain magnetic resonance images (MRIs) is the first step toward predicting prognosis, identifying high-risk patients, and evaluating treatment effects. It will lead to a more accurate estimation of prognosis, a better understanding of neurological symptoms, and a timely prediction of response to therapy. We release the first public dataset containing neonatal brain diffusion MRI and expert annotation of lesions from 133 patients diagnosed with HIE. HIE-related lesions in brain MRI are often diffuse (i.e., multi-focal), and small (over half the patients in our data having lesions occupying <1% of brain volume). Segmentation for HIE MRI data is remarkably different from, and arguably more challenging than, other segmentation tasks such as brain tumors with focal and relatively large lesions. We hope that this dataset can help fuel the development of MRI lesion segmentation methods for HIE and small diffuse lesions in general.
RESUMEN
The objective of this study was to determine the attitudes and impressions of breastfeeding mothers and healthcare practitioners towards a device concept integrating breastfeeding with infant drug and nutrient administration. This was an exploratory qualitative study involving 20 breastfeeding mothers and 6 healthcare practitioners from the Suffolk and Middlesex County areas of Massachusetts, USA each individually interviewed. Interview transcription of the semi-structured interviews by an independent service began during data collection, and data coding into major themes continued until and after data saturation was reached. Repeated medication delivery with a reusable product was highlighted as a potential use case for the device concept; ease of use and cleaning as well as cost, familiarity with the method, and infant response were identified as critical considerations. Participants questioned device suitability with liquid formulations (as opposed to non-liquid), while potential advantages over alternative medication delivery technology like oral syringes were identified, including a more "natural" feeling. Most participants had prior knowledge of, or personal experience with, devices like commercially available nipple shields. Attitudes towards the NSDS were not determined by experience with nipple shields, however. The participants' prior exposure to nipple shields is in contrast to related studies in Kenya and South Africa where commercial nipple shields were not widely known and where specific concerns surrounding potential community stigma to an unknown device were raised by participants.

BACKGROUND: Pediatric abusive head trauma (AHT) refers to head injury from intentional blunt force or violent shaking in children aged five years or less. We sought to evaluate the epidemiology of ocular injuries in AHT. METHODS: This retrospective analysis of the National Trauma Data Bank (2008 to 2014) identified children aged five years or less with AHT and ocular injuries using ICD-9-CM codes. Demographic data, types of ocular and nonocular/head injuries, geographic location, length of hospital admission, injury severity, and Glasgow Coma scores were tabulated and analyzed. RESULTS: A total of 10,545 children were admitted with AHT, and 2550 (24.2%) had associated ocular injuries; 58.7% were female. The mean age was 0.5 (±1.0) years. Most (85.7%) were aged one year or less. Common ocular injuries included contusion of eye/adnexa (73.7%) and retinal edema (59.3%), and common head injuries were subdural hemorrhage (SDH) (72.8%) and subarachnoid hemorrhage (22.9%). Retinal hemorrhages occurred in 5.3%. About 42.8% of children had injury severity scores greater than 24 (very severe), and the mortality rate was 19.2%. Children aged one year or less had the greatest odds of retinal hemorrhages (odds ratio [OR] = 2.44; P = 0.008) and SDH (OR = 1.55; P < 0.001), and the two- to three-year-old group had the greatest odds of contusions (OR = 1.68; P = 0.001), intracerebral hemorrhages (OR = 1.55; P = 0.002), and mortality (OR = 1.78; P < 0.001). For all ages, SDH occurred most frequently with retinal edema compared with other ocular injuries (OR = 2.25; P < 0.001). CONCLUSIONS AND RELEVANCE: Ocular injuries varied with age and were variably associated with nonocular injury. The youngest group was most frequently affected; however, the two- to three-year-old group was most likely to succumb to injuries.

OBJECTIVE: The study aimed to evaluate perinatal outcomes associated with introduction of and adherence to early diabetes screening guidelines. STUDY DESIGN: Retrospective cohort study of all women who received prenatal care at a single, high-volume tertiary care center before ("preguidelines") and after ("postguidelines") American College of Obstetrics and Gynecology guidelines for early pregnancy diabetes screening for women at high risk for diabetes. Women with known pregestational diabetes, late entry to prenatal care, a fetus with a known anomaly, or multiple gestation were excluded. Multivariable linear and logistic regression models were constructed to compare maternal and neonatal outcomes between women in the preguidelines cohort to those in the postguidelines cohort. Similarly, adherence to screening guidelines was assessed, and among all women who were eligible for early diabetes screening, multivariable linear, and logistic models were created to compare outcomes between those women who were screened early to those who were not. RESULTS: Of the 2,069 women eligible for analysis, 64.6% (n = 1,337) were in the postguideline cohort. Women in the postguideline cohort were older, less likely to have a history of smoking, and more likely to be non-Hispanic white. On multivariable analysis, women in the postguideline cohort had significantly less gestational weight gain (aß = -2.3; 95% confidence interval [CI]: -3.4 to -1.1), but a higher odds of 5-minute Apgar's score of <7 (adjusted odds ratio: 2.51; 95% CI: 1.11-5.66). Of 461 women who met ACOG early diabetes screening criteria, 58.7% (n = 270) were screened appropriately. Adherence to screening was associated with parity, race, insurance, and BMI. On multivariable analysis, there were no significant differences in neonatal outcomes between women meeting early screening criteria who were screened early and those who were not. CONCLUSION: Introduction of early diabetes screening guidelines was associated with a significant decrease in gestational weight gain, but did not improve neonatal outcomes. KEY POINTS: · Introduction of early diabetes screening guideline did not improve rate of early screening.. · Detection and treatment of gestational diabetes may not improve perinatal outcomes.. · Early screening guidelines was associated with decreased gestational weight..

More nurses without critical care experience are being hired by intensive care units. Eleven newly hired nurses participated in a phased program designed to improve the efficiency of intensive care unit orientation. A pre-post implementation design demonstrated that although there was a 14% reduction in orientation time, there were no statistically significant changes in new hire or preceptor satisfaction nor in first-year registered nurse turnover rates. Expansion of the program is needed to demonstrate its impact.

OBJECTIVE: In 2012, recommendations for universal tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccination during pregnancy were released. Our objective was to determine if Tdap, influenza, and pneumococcal vaccine uptake during pregnancy changed after the release of the guidelines, and identify factors associated with receiving the Tdap and influenza vaccine after 2012. METHODS: We conducted a retrospective cohort study on pregnant individuals who initiated prenatal care before 20 weeks' gestation between 11/2011-11/2012 ("pre-guideline") and 12/2012-12/2015 ("post-guideline"). Vaccine uptake dates were abstracted from medical records. The pre and post-guideline cohorts were compared to determine if Tdap vaccine uptake and timing improved after the new Tdap guidelines. We additionally examined influenza and pneumococcal vaccine uptake before and after guidelines. Factors associated with receipt of the Tdap and influenza vaccine during pregnancy in the post-guideline cohort were evaluated using multivariable logistic regression models. RESULTS: Of 2,294 eligible individuals, 1,610 (70.2%) received care in the post-guideline cohort. Among the pre-guideline cohort, 47.4% received Tdap, whereas Tdap uptake increased to 86.1% after the guidelines (p<0.001). Similarly, receiving the Tdap vaccine between the recommended time of 27-36 weeks gestational age improved from 52.5% to 91.8% after the guidelines (p<0.001). Vaccine frequency for influenza improved significantly from 61.2% to 72.0% (p<0.001), while frequency for pneumococcus were low and unchanged. An increased number of prenatal visits was associated with receiving the Tdap and influenza vaccines during pregnancy (respective, aOR 1.09 95% CI 1.05-1.13; aOR 1.50 95% CI 1.17-1.94). Non-Hispanic Black individuals were less likely to receive both the Tdap and influenza vaccines during pregnancy compared to non-Hispanic White individuals (respective, aOR 0.51 95% CI 0.33-0.80; aOR 0.68 95% CI 0.48-0.97). CONCLUSIONS: Receipt and timing of Tdap vaccine improved after implementation of the 2012 ACIP guidelines. Receipt of influenza vaccine uptake also improved during the study period, while uptake of the pneumococcal vaccine remained low. Significant racial disparities exist in receipt of Tdap and influenza vaccine during pregnancy.

Background A framework for understanding rapid diffusion changes from 0 to 6 years of age is important in the detection of neurodevelopmental disorders. Purpose To quantify patterns of normal apparent diffusion coefficient (ADC) development from 0 to 6 years of age. Materials and Methods Previously constructed age-specific ADC atlases from 201 healthy full-term children (108 male; age range, 0-6 years) with MRI scans acquired from 2006 to 2013 at one large academic hospital were analyzed to quantify four patterns: ADC trajectory, rate of ADC change, age of ADC maturation, and hemispheric asymmetries of maturation ages. Patterns were quantified in whole-brain, segmented regional, and voxelwise levels by fitting a two-term exponential model. Hemispheric asymmetries in ADC maturation ages were assessed using t tests with Bonferroni correction. Results The posterior limb of the internal capsule (mean ADC: left hemisphere, 1.18 ×103µm2/sec; right hemisphere, 1.17 ×103µm2/sec), anterior limb of the internal capsule (left, 1.11 ×103µm2/sec; right, 1.09 ×103µm2/sec), vermis (1.26 ×103µm2/sec), thalami (left, 1.17 ×103µm2/sec; right, 1.15 ×103µm2/sec), and basal ganglia (left, 1.26 ×103µm2/sec; right, 1.23 ×103µm2/sec) demonstrate low initial ADC values, indicating an earlier prenatal time course of development. ADC maturation was completed between 1.3 and 2.4 years of age, depending on the region. The vermis and left thalamus matured earliest (1.3 years). The frontolateral gray matter matured latest (right, 2.3 years; left, 2.4 years). ADC maturation occurred earlier in the left hemisphere (P < .001) in several regions, including the frontal (mean ± standard deviation) (left, 2.16 years ± 0.29; right, 2.19 years ± 0.31), temporal (left, 1.93 years ± 0.22; right, 1.99 years ± 0.22), and parietal (left, 1.92 years ± 0.30; right, 2.03 years ± 0.28) white matter. Maturation occurred earlier in the right hemisphere (P < .001) in several regions, including the thalami (left, 1.63 years ± 0.32; right, 1.45 years ± 0.33), basal ganglia (left, 1.79 years ± 0.31; right, 1.70 years ± 0.37), and hippocampi (left, 1.93 years ± 0.34; right, 1.78 years ± 0.33). Conclusion Normative apparent diffusion coefficient developmental patterns on diffusion-weighted MRI scans were quantified in children aged 0 to 6 years. This work provides knowledge about early brain development and may guide the detection of abnormal patterns of maturation. © RSNA, 2020 Online supplemental material is available for this article.

BACKGROUND: Secondary and retrospective use of hospital-hosted clinical data provides a time- and cost-efficient alternative to prospective clinical trials for biomarker development. This study aims to create a retrospective clinical dataset of Magnetic Resonance Images (MRI) and clinical records of neonatal hypoxic ischemic encephalopathy (HIE), from which clinically-relevant analytic algorithms can be developed for MRI-based HIE lesion detection and outcome prediction. METHODS: This retrospective study will use clinical registries and big data informatics tools to build a multi-site dataset that contains structural and diffusion MRI, clinical information including hospital course, short-term outcomes (during infancy), and long-term outcomes (~ 2 years of age) for at least 300 patients from multiple hospitals. DISCUSSION: Within machine learning frameworks, we will test whether the quantified deviation from our recently-developed normative brain atlases can detect abnormal regions and predict outcomes for individual patients as accurately as, or even more accurately, than human experts. Trial Registration Not applicable. This study protocol mines existing clinical data thus does not meet the ICMJE definition of a clinical trial that requires registration.

Importance: Gun violence represents a substantial public health issue, and firearm-related injuries rank second among the causes of injury-related deaths in children aged 0 to 17 years in the United States. Ocular trauma from firearm-related injuries can lead to devastating vision loss, but little is known to date about the specific demographics and characteristics of such injuries in children. Objective: To evaluate the epidemiologic pattern of pediatric firearm-related ocular injuries. Design, Setting, and Participants: This retrospective analysis used deidentified data from the National Trauma Data Bank, the largest national registry of hospitalized trauma cases in the United States. The firearm-related ocular injuries (n = 1972) of pediatric patients (defined as those younger than 21 years) hospitalized between January 1, 2008, and December 31, 2014, were analyzed. Statistical analyses were conducted from July 15, 2017, to June 15, 2019. Exposure: Firearm-related ocular trauma. Main Outcomes and Measures: Pediatric patients with firearm-related ocular injuries were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes and external causes of injury codes. Patient demographics (age, sex, and race/ethnicity), type of ocular injury, injury intent, geographic location, length of hospital admission, health insurance status, disposition at discharge, Injury Severity Score (ISS), and Glasgow Coma Scale (GCS) score were collected. Results: A total of 8715 firearm-related ocular injuries were identified. Of these injuries, 1972 (22.6%) occurred in pediatric patients, most of whom were male (1678 [85.1%]) and adolescents (1037 [52.6%]), with a mean (SD) age of 15.2 (5) years. Common locations of injury were home (761 [38.6%]) and street (490 [24.8%]). Mean (SD) hospital length of stay was 7.6 (12) days, ISS was 16 (13.1), and GCS score was 11 (5.1). The most common types of firearm-related ocular injuries were open wound of the eyeball (820 [41.6%]) and ocular adnexa (502 [25.5%]), orbital injuries or fractures (591 [30.0%]), and contusion of the eye or adnexa (417 [21.1%]). Patients aged 0 to 3 years had greater odds of unintentional injuries (odds ratio [OR], 4.41; 95% CI, 2.51-7.75; P < .001) and injuries occurring at home (OR, 5.39; 95% CI, 2.81-10.38; P < .001), and those aged 19 to 21 years had greater odds of assault injuries (OR, 2.17; 95% CI, 1.77-2.66; P < .001) and injuries occurring on the street (OR, 1.61; 95% CI, 1.3-1.98; P < .001). Black patients had the greatest odds of having injuries with assault intention (OR, 4.53; 95% CI, 3.68-5.59; P < .001), and white patients had the greatest likelihood for self-inflicted injury (OR, 7.1; 95% CI, 5.92-9.51; P < .001). Traumatic brain injury resulted mostly from self-inflicted trauma (OR, 5.99; 95% CI, 4.16-8.63; P < .001), as did visual pathway injuries (OR, 2.86; 95% CI, 1.95-4.20; P < .001). The inpatient mortality rate was 12.2%. Conclusions and Relevance: This study found that pediatric firearm-related ocular injuries from 2008 through 2014 were predominantly sight-threatening and associated with traumatic brain injury. If the possible risk factors, including sex, age, race/ethnicity, and injury intention, can be confirmed for 2015 through 2019, these findings may be useful in developing strategies to prevent pediatric firearm-related ocular injuries.

PURPOSE OF REVIEW: Myopia refers to a refractive state of the eye that can predispose to visually significant ocular disease. The prevalence of myopia is increasing worldwide. Researchers internationally have been investigating methods to slow down its progression to prevent sight-threatening complications. In this article, we perform a review of the current literature discussing interventions for preventing pediatric myopic progression. RECENT FINDINGS: Various interventions, including lifestyle modification, optical methods, and pharmacologic approaches, have been proposed to help control myopic progression. Increasing time spent outdoors can help prevent myopia onset, but has a clinically questionable effect on progression of myopia. Contact lenses that reduce peripheral retinal hyperopic defocus represent a new area of research and may hold promise as an effective intervention in myopia control. Orthokeratology shows moderate reduction rates in myopic progression whereas atropine drops, even at low doses, show the most impressive effect on slowing myopia. SUMMARY: Atropine eye drops, followed by orthokeratology lenses, are the most effective in slowing down axial elongation and myopic progression. Guidelines for use and the target populations for such interventions have not been well established and more research is warranted in these areas. Treatment should be tailored to each patient.

In the United States, competency to stand trial (CST) evaluations ensure that criminal defendants are capable of participating in their defenses, thus ensuring an important legal right. However, some research has suggested that the CST process may be impacted by legally irrelevant factors such as a defendant's race and cultural background. However, the majority of researchers examined factors that are predictive of CST recommendations and decisions. Few studies have focused on potential racial discrepancies in attorney referrals for CST evaluations and whether they are exacerbated by professional experience. The current study examined potential racial disparities in referrals for CST evaluations among 322 law students and 102 attorneys. Participants were randomly assigned to read vignettes describing either African American or Caucasian defendants who varied in their fitness to stand trial. The participants were asked to indicate whether they would refer the client for a CST evaluation and to describe their reasoning. The results indicated that both law students and attorneys were generally more likely to refer unfit rather than fit defendants, indicating an understanding of the legal criteria. Law students displayed a racial bias, only when referring the defendants who were unfit due to the lack of a rational understanding of the relevant legal case, χ2(1)â¯=â¯4.90, pâ¯=â¯0.03, Φâ¯=â¯0.13. Fitness condition was the only significant predictor of attorney referrals. The generally encouraging results indicated that professional experience did not increase racial biases.

RESUMEN
Germline RB1 mutations strongly predispose humans to cone precursor-derived retinoblastomas and strongly predispose mice to pituitary tumors, yet shared cell type-specific circuitry that sensitizes these different cell types to the loss of RB1 has not been defined. Here we show that the cell type-restricted thyroid hormone receptor isoform TRß2 sensitizes to RB1 loss in both settings by antagonizing the widely expressed and tumor-suppressive TRß1. TRß2 promoted expression of the E3 ubiquitin ligase SKP2, a critical factor for RB1-mutant tumors, by enabling EMI1/FBXO5-dependent inhibition of SKP2 degradation. In RB1 wild-type neuroblastoma cells, endogenous Rb or ectopic TRß2 was required to sustain SKP2 expression as well as cell viability and proliferation. These results suggest that in certain contexts, Rb loss enables TRß1-dependent suppression of SKP2 as a safeguard against RB1-deficient tumorigenesis. TRß2 counteracts TRß1, thus disrupting this safeguard and promoting development of RB1-deficient malignancies. Cancer Res; 77(24); 6838-50. ©2017 AACR.

As the populations of Western countries become more diverse, the risk of inaccurately generalizing knowledge from majority ethnic groups to minority groups is increasing. However, few of the measures used in forensic assessment are based on normative samples that represent the considerable diversity present in forensic settings. This study examined 4 commonly used measures of feigning: the Dot Counting Test (DCT; Boone, Lu, & Herzberg, 2002); the Miller Forensic Assessment of Symptoms (M-FAST; Miller, 2001); the Test of Memory Malingering (TOMM; Tombaugh, 1996); and a validity scale (atypical responding; ATR) on the Trauma Symptom Inventory-2 (Briere, 2011). The study compared performance on these measures of feigning among 3 groups of African immigrants: honest participants with and without posttraumatic stress disorder, and participants asked to feign distress-related symptoms. The data were used to assess the classification accuracy of each measure and the effect of demographic and cultural variables. Three of the 4 measures (M-FAST, TOMM, and ATR) significantly differentiated between participants asked to respond honestly and those asked to feign, although no measure produced higher than moderate classification accuracy. The M-FAST and DCT produced high false positive rates in the honest groups, ranging from 33% to 63%. Surprisingly, demographic and cultural variables were not significantly associated with test scores. The results emphasize the need for future related research. (PsycINFO Database Record
