- Abstract
Beneficial microorganisms are used to stimulate the germination of seeds; however, their growth-promoting mechanisms remain largely unexplored. Bacillus subtilis is commonly found in association with different plant organs, providing protection against pathogens or stimulating plant growth. We report that application of B. subtilis to melon seeds results in genetic and physiological responses in seeds that alter the metabolic and developmental status in 5-d and 1-month-old plants upon germination. We analysed mutants in different components of the extracellular matrix of B. subtilis biofilms in interaction with seeds and found cooperation in bacterial colonization of seed storage tissues and growth promotion. Combining confocal microscopy with fluorogenic probes, we found that two specific components of the extracellular matrix, amyloid protein TasA and fengycin, differentially increased the concentrations of reactive oxygen species inside seeds. Further, using electron and fluorescence microscopy and metabolomics, we showed that both TasA and fengycin targeted the oil bodies in the seed endosperm, resulting in specific changes in lipid metabolism and accumulation of glutathione-related molecules. In turn, this results in two different plant growth developmental programmes: TasA and fengycin stimulate the development of radicles, and fengycin alone stimulate the growth of adult plants and resistance in the phylloplane to the fungus Botrytis cinerea. Understanding mechanisms of bacterial growth promotion will enable the design of bespoke growth promotion strains.

BACKGROUND/OBJECTIVE: To evaluate the relation between docosahexaenoic acid (DHA) status and neurodevelopment in the offsprings of gestational diabetic mothers (ODMs). SUBJECTS/METHODS: A prospective cohort study was performed. The offspring of 63 pregnant women (23 controls, 21 diet-controlled gestational diabetes mellitus (GDM) and 19 insulin-treated GDM) were recruited. Maternal and venous cord plasma DHA percentages were analyzed. Skin temperature and activity in children were recorded for 72 h at 3 and 6 months of life. Neurodevelopment was assessed using the Bayley Scale of Infant Development II (BSID II) at 6 and 12 months of age. RESULTS: Cord plasma DHA percentage was significantly lower in the ODMs compared with that in the controls (Control 6.43 [[5.04-7.82].sup.a]; GDM+diet 5.65 [[4.44-6.86].sup.ab]; GDM+insulin 5.53 [[4.45-6.61].sup.b]). Both mental (Control 102.71 [[97.61-107.81].sup.a]; GDM+diet 100.39 [[91.43-109.35].sup.a]; GDM+insulin 93.94 [[88.31-99.57].sup.b]) and psychomotor (Control 91.52 [[81.82-101.22].sup.a]; GDM+diet 81.67 [[73.95-89.39].sup.b]; GDM+insulin 81.89 [[71.96-91.85].sup.b]) scores evaluated by the BSID II were significantly lower at 6 months in ODMs, even after adjusting for confounding factors such as breastfeeding, maternal educational level and gender. Cord plasma DHA percentage correlated with the psychomotor score from BSID II (r = 0.27;P = 0.049) and with the intra-daily variability in activity (r = -0.24; P = 0.043) at 6 months. Maternal DHA was correlated with several sleep rhythm maturation parameters at 6 months. CONCLUSIONS: Lower DHA levels in cord plasma of ODMs could affect their neurodevelopment. Maternal DHA status was also associated with higher values in the sleep rhythm maturation parameters of children.

Concordance between gram-negative enteric and other toxin-producing bacteria in blood and stool culture, endotoxin (lipopolysaccharide), and interleukin-6 (IL-6) was measured in 60 preterm infants (600-1600 g) as a clinical index in neonatal necrotizing enterocolitis (NEC). E. coli, Klebsiella, Enterobacter, and Clostridium spp., identified by routine bacteriology, were each strongly associated with elevated concentrations of endotoxin (P < 0.01) in stool filtrates, with Clostridium spp. most strongly associated with NEC disease. Stool filtrate endotoxin (EU/g) measured by a Limulus amebocyte lysate assay was age dependent. Samples from stage I NEC (61%) and infants with advanced disease (67%) had notably elevated levels of stool endotoxin (> 10 ln EU/g) compared to NEC-negative (47%) samples tested. Plasma and stool IL-6 generally tested at the low, nonmeasurable limit of the ELISA for NEC-negative (88%) and stage I NEC (93%), although a small proportion of samples (25%) from infants with stage II or III NEC had elevated stool concentrations of IL-6. We conclude that identification of toxin-producing organisms and endotoxin elevations in stool filtrates are more useful than circulating levels of endotoxin in plasma in predicting mucosally limited disease in the gastrointestinal tract. The prognostic value of monitoring stool endotoxin in infants with overgrowth of gram-negative bacteria has implications for therapeutic strategies in patients with early and advanced stages of disease. Monitoring inflammatory cytokines (IL-6) in relation to endotoxin values in stool appears of limited clinical value in controlling this devastating disease in preterm neonates. [ABSTRACT FROM AUTHOR]

19. Effect of methylene blue on refractory neonatal hypotension

Driscoll, W., Thurin, S., Carrion, V., Steinhorn, R.H., and Morin, F.C.
- Abstract
Excess nitric oxide is a mediator of the hypotension in septic shock. Nitric oxide dilates vascular smooth muscle through activation of soluble guanylate cyclase. We report the increase in blood pressure caused by methylene blue (MB), a soluble guanylate cyclase inhibitor, in five neonates with presumed septic shock unresponsive to colloids, inotropic agents, and corticosteroids. MB was given intravenously at a dose of 1 mg/kg during a 1-hour period. MB increased blood pressure in each patient (average, 33% +/- 20%). Blood pressure subsequently decreased to near baseline values in three patients, who then received a second infusion of MB. Blood pressure again increased in these patients. Three of five patients were weaned from inotropic support within 72 hours. Three of five patients survived and were discharged home. We suggest that MB increased blood pressure in these neonates with refractory hypotension. (J Pediatr 1996;129:904-8)

- Abstract
OBJECTIVE: To compare the efficacy and safety of two surfactant preparations in the treatment of respiratory distress syndrome (RDS). METHODS: We conducted a randomized, masked comparison trial at 21 centers. Infants with RDS who were undergoing mechanical ventilation were eligible for treatment with two doses of either a synthetic (Exosurf) or natural (Infasurf) surfactant if the ratio of arterial to alveolar partial pressure of oxygen was less than or equal to 0.22. Crossover treatment was allowed within 96 hours of age if severe respiratory failure (defined as two consecutive arterial/alveolar oxygen tension ratios @?0.10) persisted after two doses of the randomly assigned surfactant. Four primary outcome measures of efficacy (the incidence of pulmonary air leak [@?7 days]; the severity of RDS; the incidence of death from RDS; and the incidence of survival without bronchopulmonary dysplasia [BPD] at 28 days after birth) were compared by means of linear regression techniques. RESULTS: The primary analysis of efficacy was performed in 1033 eligible infants and an analysis of safety outcomes in the 1126 infants who received study surfactant. Preentry demographic characteristics and respiratory status were similar for the two treatment groups, except for a small but significant difference in mean gestational age (0.5 week) that favored the Infasurf treatment group. Pulmonary air leak (@?7 days) occurred in 21% of Exosurf- and 11% of Infasurf-treated infants (adjusted relative risk, 0.53; 95% confidence interval, 0.40 to 0.71; p @?0.0001). During the 72 hours after the initial surfactant treatment, the average fraction of inspired oxygen (+/-SEM) was 0.47 +/- 0.01 for Exosurf- and 0.39 +/- 0.01 for Infasurf-treated infants (difference, 0.08; 95% confidence interval, 0.06 to 0.10; p <0.0001); the average mean airway pressure (+/-SEM) was 8.6 +/- 0.1 cm H"2O for Exosurf- and 7.2 +/- 0.1 cm H"2O for Infasurf-treated infants (difference, 1.4 cm H"2O; 95% confidence interval, 1.0 to 1.8 cm H"2O; p <0.0001). The incidences of RDS-related death, total respiratory death, death to discharge, and survival without bronchopulmonary dysplasia at 28 days after birth did not differ. The number of days of more than 30% inspired oxygen and of assisted ventilation, but not the duration of hospitalization, were significantly lower in Infasurf-treated infants. CONCLUSION: Compared with Exosurf, Infasurf provided more effective therapy for RDS as assessed by significant reductions in the severity of respiratory disease and in the incidence of air leak complications.

Abstract Background Mangotoxin is an antimetabolite toxin that is produced by strains of Pseudomonas syringae pv. syringae; mangotoxin-producing strains are primarily isolated from mango tissues with symptoms of bacterial apical necrosis. The toxin is an oligopeptide that inhibits ornithine N-acetyl transferase (OAT), a key enzyme in the biosynthetic pathway of the essential amino acids ornithine and arginine. The involvement of a putative nonribosomal peptide synthetase gene (mgoA) in mangotoxin production and virulence has been reported. Results In the present study, we performed a RT-PCR analysis, insertional inactivation mutagenesis, a promoter expression analysis and terminator localisation to study the gene cluster containing the mgoA gene. Additionally, we evaluated the importance of mgoC, mgoA and mgoD in mangotoxin production. A sequence analysis revealed an operon-like organisation. A promoter sequence was located upstream of the mgoB gene and was found to drive lacZ transcription. Two terminators were located downstream of the mgoD gene. RT-PCR experiments indicated that the four genes (mgoBCAD) constitute a transcriptional unit. This operon is similar in genetic organisation to those in the three other P. syringae pathovars for which complete genomes are available (P. syringae pv. syringae B728a, P. syringae pv. tomato DC3000 and P. syringae pv. phaseolicola 1448A). Interestingly, none of these three reference strains is capable of producing mangotoxin. Additionally, extract complementation resulted in a recovery of mangotoxin production when the defective mutant was complemented with wild-type extracts. Conclusions The results of this study confirm that mgoB, mgoC, mgoA and mgoD function as a transcriptional unit and operon. While this operon is composed of four genes, only the last three are directly involved in mangotoxin production.

- Abstract
Background: Previous studies suggest that improvement in symptoms of posttraumatic stress disorder (PTSD) is accompanied by changes in neural connectivity, however, few studies have investigated directional (effective) connectivity. The current study assesses treatment-related changes in effective connectivity in youth with PTSD undergoing Trauma-Focused Cognitive Behavioral Therapy (TF-CBT)., Methods: Functional MRI scans before and after 16 weeks of TF-CBT for 20 youth with PTSD, or the same time interval for 20 healthy controls (HC) were included in the analysis. Structural equation modeling was used to model group differences in directional connectivity at baseline, and changes in connectivity from pre- to post-treatment., Results: At baseline, the PTSD group, relative to the HC group, had significantly greater connectivity in the path from dorsal cingulate to anterior cingulate and from dorsal cingulate to posterior cingulate corticies. From pre- to post-treatment, connectivity in these paths decreased significantly in the PTSD group, as did connectivity from right hippocampus to left superior temporal gyrus. Connectivity from the left amygdala to the lateral orbital frontal cortex was significantly lower in PTSD vs HC at baseline, but did not change from pre- to post-treatment., Conclusion: Although based on a small sample, these results converge with previous studies in suggesting a central role for the dorsal cingulate cortex in PTSD symptoms. The direction of this connectivity suggests that the dorsal cingulate is the source of modulation of anterior and posterior cingulate cortex during trauma-focused cognitive behavioral therapy., Competing Interests: Declaration of competing interest None of the authors have conflicts of interest to report., (Published by Elsevier B.V.)

- Abstract
Study Objectives: Poor sleep impedes children's cognitive, emotional, and psychosocial development. Pediatric sleep dysregulation is common, and children who live in communities of low socioeconomic status experience additional risk factors for short sleep duration and poor sleep quality. School-based training in mindfulness and yoga-informed practices can improve children's behavior and well-being, but effects on objectively measured sleep are unknown., Methods: Effects of a school-based health and mindfulness curriculum, which taught practices such as paced breathing, on sleep and stress were examined in 115 children (49 girls, ages 8 to 11 at baseline). Fifty-eight children in a community of low socioeconomic status received the curriculum twice weekly for 2 years. Fifty-seven children in a socioeconomic status-matched community engaged in their usual physical education class instead. In-home ambulatory polysomnography and perceived social stress were measured in all children at 3 time points: at baseline (ie, prior to curriculum exposure) and at 2 yearly follow-ups., Results: Children receiving the curriculum gained an average of 74 minutes of total sleep time, and 24 minutes of rapid eye movement sleep, per night over the 2-year study period. Children not receiving the curriculum experienced a decrease in total sleep time averaging 64 minutes per night, with no changes in rapid eye movement sleep. Sleep improved within the first 3 months of curriculum exposure, in a dose-dependent fashion. Higher curriculum engagement (eg, using the breathing exercises outside of class) was associated with larger gains in total and rapid eye movement sleep duration. Aggregate within-group changes in social stress were not significant. However, among children receiving the curriculum, those who experienced larger gains in total and rapid eye movement sleep duration also experienced larger increases in perceived social stress., Conclusions: A school-based health and mindfulness curriculum improved children's objectively measured sleep over 2 years. Social stress did not mediate these effects; instead, mindfulness training may have increased awareness of environmental stressors, while developing tools to reduce stress vulnerability., Citation: Chick CF, Singh A, Anker LA, et al.

- Abstract
This study investigated group differences and longitudinal changes in brain volume before and after trauma-focused cognitive behavioral therapy (TF-CBT) in 20 unmedicated youth with maltreatment-related posttraumatic stress disorder (PTSD) and 20 non-trauma-exposed healthy control (HC) participants. We collected MRI scans of brain anatomy before and after 5 months of TF-CBT or the same time interval for the HC group. FreeSurfer software was used to segment brain images into 95 cortical and subcortical volumes, which were submitted to optimal scaling regression with lasso variable selection. The resulting model of group differences at baseline included larger right medial orbital frontal and left posterior cingulate corticies and smaller right midcingulate and right precuneus corticies in the PTSD relative to the HC group, R
2 = .67. The model of group differences in pre- to posttreatment change included greater longitudinal changes in right rostral middle frontal, left pars triangularis, right entorhinal, and left cuneus corticies in the PTSD relative to the HC group, R2 = .69. Within the PTSD group, pre- to posttreatment symptom improvement was modeled by longitudinal decreases in the left posterior cingulate cortex, R2 = .45, and predicted by baseline measures of a smaller right isthmus (retrosplenial) cingulate and larger left caudate, R2 = .77. In sum, treatment was associated with longitudinal changes in brain regions that support executive functioning but not those that discriminated PTSD from HC participants at baseline. Additionally, results confirm a role for the posterior/retrosplenial cingulate as a correlate of PTSD symptom improvement and predictor of treatment outcome., (© 2021 International Society for Traumatic Stress Studies.)- Published

- Abstract
Purpose: Few of the existing evidence-based interventions for child trauma exposure were specifically designed to address experiences and outcomes of complex developmental trauma. Stanford's cue-centered therapy (CCT) was designed to address this gap by offering a flexible, integrative, and insight-oriented treatment approach that is grounded in principles of neuroscience, developmental trauma, client empowerment, and allostasis. This article reviews the CCT rationale, treatment components, evidence base, and training approach., Recent Findings: Studies demonstrate promising outcomes indicating CCT effectiveness in reducing child and caregiver posttraumatic stress, and in improving child functioning. Further research, however, is needed to identify which clients are best-suited for CCT (versus other available child trauma treatments) and to identify which components of CCT are most critical for addressing complex developmental trauma., Summary: CCT advances the field of child trauma treatment by offering an intervention approach focused on addressing complex developmental trauma. Positive treatment and training outcomes indicate utility of CCT for clients and clinicians. Innovations in research and training approaches are needed to further dissemination and implementation of CCT and other related child trauma interventions for complex developmental trauma., (© The Author(s), under exclusive licence to Springer Nature Switzerland AG 2021.)

- Abstract
Inhibitory control is fundamental to children's self-regulation and cognitive development. Here we investigate cortical-basal ganglia pathways underlying inhibitory control in children and their adult-like maturity. We first conduct a comprehensive meta-analysis of extant neurodevelopmental studies of inhibitory control and highlight important gaps in the literature. Second, we examine cortical-basal ganglia activation during inhibitory control in children ages 9-12 and demonstrate the formation of an adult-like inhibitory control network by late childhood. Third, we develop a neural maturation index (NMI), which assesses the similarity of brain activation patterns between children and adults, and demonstrate that higher NMI in children predicts better inhibitory control. Fourth, we show that activity in the subthalamic nucleus and its effective connectivity with the right anterior insula predicts children's inhibitory control. Fifth, we replicate our findings across multiple cohorts. Our findings provide insights into cortical-basal ganglia circuits and global brain organization underlying the development of inhibitory control.

- Abstract
Background: Previous studies indicate that youth with posttraumatic stress disorder (PTSD) have abnormal activation in brain regions important for emotion processing. It is unknown whether symptom improvement is accompanied by normative changes in these regions. This study identified neural changes associated with symptom improvement with the long-term goal of identifying malleable targets for interventions., Methods: A total of 80 functional magnetic resonance imaging (fMRI) scans were collected, including 20 adolescents with PTSD (ages 9-17) and 20 age- and sex-matched healthy control subjects, each scanned before and after a 5-month period. Trauma-focused cognitive behavioral therapy was provided to the PTSD group to ensure improvement in symptoms. Whole brain voxel-wise activation and region of interest analyses of facial expression task data were conducted to identify abnormalities in the PTSD group versus HC at baseline (BL), and neural changes correlated with symptom improvement from BL to EOS of study (EOS)., Results: At BL, the PTSD group had abnormally elevated activation in the cingulate cortex, hippocampus, amygdala, and medial frontal cortex compared to HC. From BL to EOS, PTSD symptoms improved an average of 39%. Longitudinal improvement in symptoms of PTSD was associated with decreasing activation in posterior cingulate, mid-cingulate, and hippocampus, while improvement in dissociative symptoms was correlated with decreasing activation in the amygdala., Conclusions: Abnormalities in emotion-processing brain networks in youth with PTSD normalize when symptoms improve, demonstrating neural plasticity of these regions in young patients and the importance of early intervention., (Copyright © 2019.

- Abstract
Background: The 2010 neonatal resuscitation program (NRP) guidelines incorporate ventilation corrective steps (using the mnemonic--MRSOPA) into the resuscitation algorithm. The perception of neonatal providers, time taken to perform these maneuvers or the effectiveness of these additional steps has not been evaluated., Methods: Using two simulated clinical scenarios of varying degrees of cardiovascular compromise--perinatal asphyxia with (i) bradycardia (heart rate--40 min(-1)) and (ii) cardiac arrest, 35 NRP certified providers were evaluated for preference to performing these corrective measures, the time taken for performing these steps and time to onset of chest compressions., Results: The average time taken to perform ventilation corrective steps (MRSOPA) was 48.9 ± 21.4s. Providers were less likely to perform corrective steps and proceed directly to endotracheal intubation in the scenario of cardiac arrest as compared to a state of bradycardia. Cardiac compressions were initiated significantly sooner in the scenario of cardiac arrest 89 ± 24 s as compared to severe bradycardia 122 ± 23 s, p < 0.0001. There were no differences in the time taken to initiation of chest compressions between physicians or mid-level care providers or with the level of experience of the provider., Conclusions: Effective ventilation of the lungs with corrective steps using a mask is important in most cases of neonatal resuscitation. Neonatal resuscitators prefer early endotracheal intubation and initiation of chest compressions in the presence of asystolic cardiac arrest. Corrective ventilation steps can potentially postpone initiation of chest compressions and may delay return of spontaneous circulation in the presence of severe cardiovascular compromise., (Copyright © 2015 Elsevier Ireland Ltd.

- Abstract
Importance: Full-term neonates born between 37 and 41 weeks' gestational age have been considered a homogeneous, low-risk group. However, recent evidence from studies based on mode of delivery has pointed toward increased morbidity associated with early-term cesarean section births (37-38 weeks) compared with term neonates (39-41 weeks)., Objective: To compare the short-term morbidity of early-term vs term neonates in a county-based birth cohort using the primary objective of admission to a neonatal intensive care unit (NICU) or neonatology service., Design, Setting, and Participants: Retrospective population-based 3-year birth cohort study (January 1, 2006-December 31, 2008) at all major birth hospitals in Erie County, New York. All full-term live births comprised the birth cohort; this information was obtained from the hospitals' perinatal databases, and data pertaining to NICU or neonatology service admissions were extracted from individual medical records., Exposure: Gestational age of early term (37(0/7)-38(6/7) weeks) vs term (39(0/7)-41(0/7) weeks)., Main Outcomes and Measures: Admission to the NICU or neonatology service., Results: There were 33,488 live births during the 3-year period, of which 29,741 had a gestational age between 37 and 41 weeks. Of all live births, 9031 (27.0%) were early term. Compared with term infants, early-term neonates had significantly higher risks for the following: hypoglycemia (4.9% vs 2.5%; adjusted odds ratio [OR], 1.92), NICU or neonatology service admission (8.8% vs 5.3%; adjusted OR, 1.64), need for respiratory support (2.0% vs 1.1%; adjusted OR, 1.93), requirement for intravenous fluids (7.5% vs 4.4%; adjusted OR, 1.68), treatment with intravenous antibiotics (2.6% vs 1.6%; adjusted OR, 1.62), and mechanical ventilation or intubation (0.6% vs 0.1%; adjusted OR, 4.57). Delivery by cesarean section was common among early-term births (38.4%) and increased the risk for NICU or neonatology service admission (12.2%) and morbidity (7.5%) compared with term births. Among vaginal deliveries, early-term neonates (6.8%) had a significantly higher rate of NICU or neonatology service admission compared with term neonates (4.4%)., Conclusions and Relevance: Early-term births are associated with high neonatal morbidity and with NICU or neonatology service admission. Evaluation of local prevalence data will assist in implementation of specific preventive measures and plans, as well as prioritize limited health care resources.

- Abstract
Many studies have provided strong evidence of a fundamental and complex role for sleep disturbances in adult posttraumatic stress disorder (PTSD). Investigations of adult PTSD using subjective and objective measures document sleep architecture abnormalities and high prevalence of sleep disordered breathing, periodic limb movement disorder, nightmares, and insomnia. PTSD treatment methods do appear to significantly improve sleep disturbance, and also studies suggest that treatments for sleep disorders often result in improvements in PTSD symptoms. Further, the most recent evidence suggests sleep abnormalities may precede the development of PTSD. Given the importance of sleep disorders to the onset, course, and treatment of adult PTSD, examination of sleep disturbances far earlier in the life course is imperative. Here we review the literature on what we know about sleep disturbances and disorders in pediatric PTSD. Our review indicates that the extant, empirical data examining sleep disturbance and disorders in pediatric PTSD is limited. Yet, this literature suggests there are significantly higher reports of sleep disturbances and nightmares in children and adolescents exposed to trauma and/or diagnosed with PTSD than in non-trauma-exposed samples. Sleep questionnaires are predominantly employed to assess sleep disorders in pediatric PTSD, with few studies utilizing objective measures. Given the important, complex relationship being uncovered between adult PTSD and sleep, this review calls for further research of sleep in children with PTSD using more specific subjective measures and also objective measures, such as polysomnography and eventually treatment trial studies.

- Abstract
Objective: To compare the efficacy of vinyl bags and thermal warming mattresses in preventing hypothermia during delivery room resuscitation and stabilization of extremely low-gestational-age neonates (ELGANs)., Study Design: Preterm infants 23 to 28 weeks' gestational age were randomly allocated to either vinyl bag or thermal mattress group at delivery to prevent hypothermia. The primary outcome of the study was the axillary temperature on admission to the neonatal intensive care unit., Results: A total of 41 infants were enrolled in the study. The mean admission temperature in the vinyl bag group was 36.1°C ± 0.7°C as compared with 35.8°C ± 1.3°C in the thermal mattress group. The subgroup of these infants with lower birth weight (<750 g) had significantly higher admission temperature with vinyl bags (36°C ± 0.4°C) compared with thermal mattress (35°C ± 1.3°C)., Conclusion: Vinyl bags and warming mattress are equally effective in improving admission temperature in ELGANs. Improvements in other areas such as delivery room temperature may be needed to achieve the goal of preventing hypothermia in this vulnerable population., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

- Abstract
Objective: This study examined activation to facial expressions in youth with a history of interpersonal trauma and current posttraumatic stress symptoms (PTSS) compared to healthy controls (HC)., Design and Analysis: Twenty-three medication-naive youth with PTSS and 23 age- and gender-matched HC underwent functional magnetic resonance imaging (fMRI) while viewing fearful, angry, sad, happy, and neutral faces. Data were analyzed for group differences in location of activation, as well as timing of activation during the early versus late phase of the block. Using SPM5, significant activation (P < .05 FWE [Family-Wise Error] corrected, extent = 10 voxels) associated with the main effect of group was identified. Activation from selected clusters was extracted to SPSS software for further analysis of specific facial expressions and temporal patterns of activation., Results: The PTSS group showed significantly greater activation than controls in several regions, including the amygdala/hippocampus, medial prefrontal cortex, insula, and ventrolateral prefrontal cortex, and less activation than controls in the dorsolateral prefrontal cortex (DLPFC). These group differences in activation were greatest during angry, happy, and neutral faces, and predominantly during the early phase of the block. Post hoc analyses showed significant Group × Phase interactions in the right amygdala and left hippocampus., Conclusions: Traumatic stress may impact development of brain regions important for emotion processing. Timing of activation may be altered in youth with PTSS., (© 2012 Wiley Periodicals, Inc.)

- Abstract
Invasive alien mammals are the major driver of biodiversity loss and ecosystem degradation on islands. Over the past three decades, invasive mammal eradication from islands has become one of society's most powerful tools for preventing extinction of insular endemics and restoring insular ecosystems. As practitioners tackle larger islands for restoration, three factors will heavily influence success and outcomes: the degree of local support, the ability to mitigate for non-target impacts, and the ability to eradicate non-native species more cost-effectively. Investments in removing invasive species, however, must be weighed against the risk of reintroduction. One way to reduce reintroduction risks is to eradicate the target invasive species from an entire archipelago, and thus eliminate readily available sources. We illustrate the costs and benefits of this approach with the efforts to remove invasive goats from the Galápagos Islands. Project Isabela, the world's largest island restoration effort to date, removed >140,000 goats from >500,000 ha for a cost of US$10.5 million. Leveraging the capacity built during Project Isabela, and given that goat reintroductions have been common over the past decade, we implemented an archipelago-wide goat eradication strategy. Feral goats remain on three islands in the archipelago, and removal efforts are underway. Efforts on the Galápagos Islands demonstrate that for some species, island size is no longer the limiting factor with respect to eradication. Rather, bureaucratic processes, financing, political will, and stakeholder approval appear to be the new challenges. Eradication efforts have delivered a suite of biodiversity benefits that are in the process of revealing themselves. The costs of rectifying intentional reintroductions are high in terms of financial and human resources. Reducing the archipelago-wide goat density to low levels is a technical approach to reducing reintroduction risk in the short-term, and is being complemented with a longer-term social approach focused on education and governance.

- Abstract
We examined the efficacy of divalproex sodium (DVP) for the treatment of PTSD in conduct disorder, utilizing a previous study in which 71 youth were enrolled in a randomized controlled clinical trial. Twelve had PTSD. Subjects (all males, mean age 16, SD 1.0) were randomized into high and low dose conditions. Clinical Global Impression (CGI) ratings for core PTSD symptoms (Intrusion, avoidance and hyper arousal) were primary outcome measures, weekly slopes of impulsivity secondary ones. Intent-to-treat analyses showed significant positive associations between receiving high dose of DVP CGI's. Parallel analyses comparing outcome by drug level achieved strengthened the results.

- Abstract
Objective: To examine the structure of emotions and affective dysregulation in juvenile delinquents., Method: Fifty-six juvenile delinquents from a local juvenile hall and 169 subjects from a local high school were recruited for this study. All participants completed psychometric testing for trait emotions followed by measurements of state emotions under two conditions (free association and stress condition). Finally, delinquent participants completed a detailed assessment of past trauma using the Childhood Trauma Interview (CTI)., Results: Delinquents exhibit significantly higher levels of negative state and trait emotions when compared to a high school sample. In the delinquent sample chronicity of physical trauma affects the longstanding variable of trait emotionality and severity of trauma, specifically emotional abuse and witnessing violence, shapes negative emotional outcomes in state emotionality. In addition, delinquents appear to experience a wider range of emotions than the comparison sample and were more likely to experience a confluence of state emotions of sadness and anger under stressed conditions., Conclusion: Adolescent delinquents appear to have a different experience of negative emotions than comparison adolescents. The experience of emotions appears to differ in state and trait conditions. These emotions may be related to childhood experiences of trauma.

- Abstract
Objective: To compare the effect of standard care vs. the use of vinyl bags (Vi-Drape (R) isolation bag) on admission temperature in extremely premature infants < or = 28 weeks gestational age at birth., Methods: Twenty seven premature infants with similar baseline characteristics were assigned and placed in vinyl bags (n=14) immediately following delivery without drying or received standard care (controls, n=13), including drying and placement under a radiant warmer. Axillary temperature was recorded on admission to the neonatal unit., Results: The average temperature in the vinyl bag group was significantly higher (35.9 +/- 0.13 vs 34.9 +/- 0.24 degrees C, p=0.002). Although the cord blood pH was similar between the two groups (7.33+0.02 in the vinyl bag group and 7.33 +/- 0.01 in the control group), the worst pH in the first 6 hours of life was significantly lower in the control group (7.32 +/- 0.02 vs 7.22 +/- 0.04, p=0.03). There was a significant increase in maximal oxygen requirement during the first 24 h in the control group (82.9 vs 43.3% in the vinyl bag group, p=0.0004)., Conclusion: Vinyl bags prevent heat loss and are a simple and effective intervention in preventing hypothermia in the delivery room and early acidosis in premature infants.

- Abstract
Background: Reported rubella cases in the United States are at the lowest numbers since the introduction of vaccine, suggesting that endemic transmission may have been interrupted. It is necessary to validate that the observed absence of rubella is due to the disappearance of disease rather than a failure of rubella surveillance., Methods: Adequate rubella surveillance to detect ongoing transmission is characterized by evidence that rubella investigations are being conducted, detection of importations, and lack of spread from confirmed cases. We reviewed rubella surveillance data and activities from 5 sources: (1) data reported to the national surveillance system; (2) a survey of health departments and public health laboratories, including questions regarding any links between measles and rubella surveillance; (3) enhanced rubella surveillance activities in California and in New York City; (4) sentinel surveillance along the US-Mexico border; and (5) case detection in 8 large health maintenance organizations (HMOs)., Results: During 2002-2004, 35 cases of rubella were reported to the national system, including 12 (34%) imported cases. The 39 programs that responded to our survey reported conducting 1482 investigations for rubella; according to another national survey, 1921 investigations were conducted for measles. Forty-one laboratories responded to our survey and reported conducting 6428 tests for acute rubella. No previously undetected (or unreported) cases of rubella or congenital rubella syndrome were identified by our survey or reviews of surveillance in California, New York, and along the US-Mexico border, and no additional cases were detected in the HMO database., Conclusions: No previously unrecognized spread cases or outbreaks of rubella were detected. Surveillance in the United States is sufficiently sensitive to identify indigenous cases of rubella, if they were occurring, supporting the contention that rubella has been eliminated from the United States.

- Abstract
This study examined the relationship of dissociative symptoms, abuse and neglect, and gender to mean heart rate (HR) in two types of interviews. Participants were 25 female and 16 male delinquent adolescents. Dissociative symptoms and abuse and neglect were assessed by structured interviews. Participants were randomized to one of two conditions, to describe either their most stressful life experience or their free association thoughts. Greater dissociative symptoms were associated with lower mean HR, whereas abuse and neglect, being a girl, and participating in the free association task were associated with higher mean HR. The finding that high levels of dissociative symptoms may be related to a suppression of autonomic physiological responses to stress support Bremner's conceptualization (J. D. Bremner, 1999) that dissociative symptoms comprise one of two subtypes of the acute stress response, differing physiologically as well as subjectively from a predominantly hyperarousal or intrusive symptom response.

- Abstract
Concordance between gram-negative enteric and other toxin-producing bacteria in blood and stool culture, endotoxin (lipopolysaccharide), and interleukin 6 (IL-6) was measured in 60 preterm infants (600-1600 g) as a clinical index in neonatal necrotizing enterocolitis (NEC). Escherichia coli, Klebsiella, Enterobacter, and Clostridium spp, identified by routine bacteriology, were each strongly associated with elevated concentrations of endotoxin (P < 0.01) in stool filtrates with Clostridium spp most strongly associated with NEC disease. Stool filtrate endotoxin (endotoxin units [EU] per gram) measured by a Limulus amebocyte lysate assay was age-dependent. Samples from stage I NEC (61%) and infants with advanced disease (67%) had notably elevated levels of stool endotoxin (>10 ln EU/g) compared with NEC-negative (47%) samples tested. Plasma and stool IL-6 generally tested at the low, nonmeasurable limit of the enzyme-linked immunosorbent assay (ELISA) for NEC-negative (88%) and stage I NEC (93%), although a small proportion of samples (25%) from infants with stage II or II NEC had elevated stool concentrations of IL-6. We conclude that identification of toxin-producing organisms and endotoxin elevations in stool filtrates are more useful than circulating levels of endotoxin in plasma in predicting mucosally limited disease in the gastrointestinal tract. The prognostic value of monitoring stool endotoxin in infants with overgrowth of gram-negative bacteria has implications for therapeutic strategies for patients with early and advanced stages of disease. Monitoring inflammatory cytokines (IL-6) in relation to endotoxin values in stool appears of limited clinical value in controlling this devastating disease in preterm neonates.

- Abstract
Objectives: To assess history of trauma and dissociation in a group of juvenile delinquents and to assess how adolescents would respond to a structured interview for dissociative symptoms., Method: Sixty-four adolescents in juvenile probation hall participated in 2 investigational sessions in 1996-1997. For session 1 they answered the Childhood Trauma Questionnaire (CTQ), the Response Evaluation Measure for Youth-71 (REMY-71), and the Weinberger Adjustment Inventory. For session 2 they were given the Childhood Trauma Interview (CTI) and the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D)., Results: In this sample 28.3% met criteria for a dissociative disorder and 96.8% endorsed a history of traumatic events. There were significant positive correlations between CTI and CTQ trauma scores and SCID-D and REMY-71 dissociative symptoms. All dissociative symptoms were endorsed, but depersonalization was the most common experience. There was a lack of congruence between the different methods of assessing dissociation., Conclusions: This study provides support for an early link between history of trauma and dissociation. Adolescents were able to answer questions from a structured interview assessing dissociation.

- Abstract
Bacterial translocation and enteral feeding are factors implicated in neonatal necrotizing enterocolitis (NEC) in the preterm infant. A cohort of 60 preterm low birth-weight (LBW) infants (600-1,600 g at birth) consecutively admitted to the neonatal intensive care unit (NICU; N = 183) were prospectively followed to evaluate the role of bacterial endotoxins (lipopolysaccharides) and enteral feeding in the development of NEC. Stage I NEC was identified in 14/60 (23%) infants. In all, 15% (9/60) of infants followed, which represented roughly 5% of higher risk, LBW infants admitted to the NICU, progressed to Stage II or III NEC disease. Infants not enterally fed (nothing by mouth [NPO]) were at greatest risk of developing NEC. No infant who was breast milk fed progressed to Stage II or III NEC. The protective effect of breast milk was most evident when compared with the combined group of NPO or formula-feeding infants per person-week at risk (RR = .15, P < .04). Toxin-producing bacteria and endotoxin levels in stool filtrates predicted early and advanced stages of NEC disease. Cytokine concentrations (interleukin-6 [IL-6]) in stool appeared of limited value in reflecting mucosally limited disease in the gastrointestinal tract. Overgrowth of toxin-producing bacteria and their toxin products may adversely affect gut barrier function; monitoring endotoxin concentrations in stool filtrates may be most clinically useful in NPO and formula-fed infants identified at risk of developing NEC.

- Abstract
Background: Cardiopulmonary resuscitation, a potentially lifesaving procedure, is initiated on hospitalized patients who have an arrest in the absence of a written do-not-resuscitate (DNR) order. New York State Law specifies that attending physicians may write a DNR order on an adult patient either with his/her consent or that of a surrogate. Under specified circumstances, concurring physician and witness signatures are also required. This study examines potential obstacles physicians may encounter when implementing a DNR order for a hospitalized patient., Methods: Sixty house staff officers and 45 attending physicians at two New York City medical centers responded to a questionnaire listing 18 potential problems in obtaining a DNR order. Using a Likert scale, respondents rated the prevalence of each problem., Results: Analysis of the data indicates that attending physician's failure to discuss DNR issues with patients and situations involving surrogate decision making are considered major obstacles to obtaining a DNR order. Procedural regulations, including abundant paperwork and witnessed signatures, are not identified as major obstacles., Conclusions: This study suggests a need for improved communication among physicians, patients, and surrogates about advance directives, when feasible, either prior to hospitalization or early in its course, in an effort to comply with DNR legislation in a manner that reflects the patient's wishes and best interests.
