When presented with decisions that require simultaneously weighing self-benefit and other harm, adolescents with callous-unemotional traits compared with controls engage in less Costly Helping (i.e., giving up a benefit to protect a beneficent other). Young adults completed questionnaires, played an online-administered game of Costly Helping, and viewed an Elevation stimulus video (when witnessing another’s act of virtue, individuals may experience a positive or elevating response). Subjects were assigned to one of four study arms, which varied the order of presentation. Higher levels of Factor 1 (callousness) psychopathic trait scale scores (assessed using the Levenson Self-Report Psychopathy Scale) were associated with significantly less Costly Helping. Elevation associated positively with Costly Helping behaviors and negatively with psychopathic traits. Introducing Elevation as an independent variable in regression analyses attenuated the relationship between psychopathic traits and Costly Helping, suggesting mediation. Those viewing the Elevation stimulus video prior to playing the game, as opposed to after, trended toward more Costly Helping by taking less money for themselves ($3.28 vs. $3.72). Results support that this simple game provides meaningful behavioral data associated with psychopathic traits. Differences in Elevation may, in part, explain the observed differences in prosocial behavior in those with high psychopathic traits.

BACKGROUND AND AIMS: Adolescents with conduct and substance use problems are at increased risk for premature mortality, but the extent to which these risk factors reflect family- or individual-level differences and account for shared or unique variance is unknown. This study examined common and independent contributions to mortality hazard in adolescents ascertained for conduct disorder (CD) and substance use disorder (SUD), their siblings and community controls, hypothesizing that individual differences in CD and SUD severity would explain unique variation in mortality risk beyond that due to clinical/control status and demographic factors. DESIGN: Mortality analysis in a prospective study (Genetics of Antisocial Drug Dependence Study) that began in 1993. Multi-site sample recruited in San Diego, California and Denver, Colorado, USA. PARTICIPANTS: A total of 1463 clinical probands were recruited through the juvenile correctional system, court-mandated substance abuse treatment programs and correctional schools, along with 1399 of their siblings, and 904 controls. MEASUREMENTS: Mortality and cause-of-death were assessed via National Death Index search (released October, 2017). FINDINGS: There were 104 deaths documented among 3766 (1168 female) adolescents and young adults (average age 16.79 years at assessment, 32.69 years at death/censoring). Mortality hazard for clinical probands and their siblings was 4.99 times greater than that of controls (95% confidence interval = 2.40-10.40; P

To evaluate marijuana use by adolescents and young adults with inflammatory bowel disease (IBD).This descriptive cross-sectional study of patients seen between December 2015 through June 2017 at Children's Hospital Colorado for IBD enrolled patients 13-23 years of age, independent of marijuana use status. Information obtained consisted of chart review, electronic and interview self-report, and serum cannabinoid levels. Marijuana ever-users were compared with never-users for clinical characteristics and perceptions of risk with use; users provided information on routes, patterns, motivations, and perceived benefits and problems with use.Of 99 participants, ever-use was endorsed by 32% (32 of 99) and daily or almost daily use by 9% (9 of 99). Older age was the only characteristic related to endorsing marijuana use. Twenty-nine ever-users completed all questionnaires. After adjusting for age, users were 10.7 times more likely to perceive low risk of harm with regular use (P .001). At least 1 medical reason for use was endorsed by 57% (17 of 30), most commonly for relief of physical pain (53%, 16 of 30) (2 did not complete all questionnaires). Problems from use were identified by 37% (11 of 30), most commonly craving/strong urge to use. Most common route of use was smoking (83%) followed by edibles (50%), dabbing (40%), and vaping (30%).Marijuana use by adolescents and young adults with IBD is common and perceived as beneficial. Guidelines for screening, testing, and counseling of marijuana use should be developed for patients with IBD.

PURPOSE: Although cesarean delivery is the most common surgical procedure in the United States, postoperative opioid prescribing varies greatly. We hypothesized that patient characteristics, procedural characteristics, or both would be associated with high vs low opioid use after discharge. This information could help individualize prescriptions. METHODS: In this prospective cohort study, we quantified opioid use for 4 weeks following hospital discharge after cesarean delivery. Predischarge characteristics were obtained from health records, and patients self-reported total opioid use postdischarge on weekly questionnaires. Opioid use was quantified in milligram morphine equivalents (MMEs). Binomial and Poisson regression analyses were performed to assess predictors of opioid use after discharge. RESULTS: Of the 233 patients starting the study, 203 (87.1%) completed at least 1 questionnaire and were included in analyses (86.3% completed all 4 questionnaires). A total of 113 patients were high users (>75 MMEs) and 90 patients were low users (≤75 MMEs) of opioids postdischarge. The group reporting low opioid use received on average 44% fewer opioids in the 24 hours before discharge compared with the group reporting high opioid use (mean = 33.0 vs 59.3 MMEs, P

Objectives The aim of the study was to describe use of oral or sublingual cannabis oil (CO) by adolescent and young adult patients with inflammatory bowel disease (IBD). Methods A descriptive study of IBD patients 13 to 23 years of age seen between January 2015 through December 2017 at Children's Hospital Colorado. Information obtained included chart abstraction, electronic and interview self-report, and serum cannabinoid levels. We compared CO users and cannabis non-users for clinical characteristics and perceptions of risk. Users of CO provided information on routes, patterns, motivations, and perceived benefits and problems with use. Results The 15 users and 67 non-users were similar for clinical characteristics and pain and appetite scores. 9 of 15 (60%) CO users had used in the past 30 days, an average of 22 ± 9 times; and 4 used daily. A variety of strengths and CBD:THC ratios were reported. Most common perceived effect of use was on sleep quality, nausea, and increase in appetite. Of the 15 users, 6 used only CO and no additional forms of cannabis. Of these 6 CO only users, 5 reported a medical reason for use, most commonly to relieve pain. Conclusions Adolescent and young adults with IBD used oral CO and many used other cannabis products as well. Users perceived some medical benefit. Care teams should strive for open communication about use until further information on safety and efficacy becomes available.

To our knowledge, this is the first study to examine the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5-defined conduct disorder (CD) with limited prosocial emotions (LPE) among adolescents in substance use disorder (SUD) treatment, despite the high rates of CD in this population. We tested previously published methods of LPE categorization in a sample of male conduct-disordered patients in SUD treatment (N = 196). CD with LPE patients did not demonstrate a distinct pattern in terms of demographics or comorbidity regardless of the categorization method utilized. In conclusion, LPE, as operationalized here, does not identify a distinct subgroup of patients based on psychiatric comorbidity, SUD diagnoses, or demographics.

Objective: The purpose of this article is to discuss how telemental healthcare and the patient-centered medical home (PCMH) can be integrated to improve the quality of mental healthcare available. Methods: This article outlines the components of a PCMH, and how the needs of this type of system of care can benefit from telemental healthcare. Results: The princples of PCMHs are being increasingly promoted in a variety of settings. In order to fulfill these principles, mental heathcare must be a integral part of the care provided to patients within the PCMH. The mental healthcare workforce is inadequate to provide care for patients, particularly in rural and high-poverty areas. Telemental healthcare provides a means to extend mental health services to the PCMHs using a variety of models. Conclusions: Telemental healthcare offers unique opportunities to bridge the need for mental healthcare integration in the PCMH for all patients.

BACKGROUND: Knowledge of incidence and risk factors for long-term opioid prescribing is critical for surgical patients. In this retrospective cohort study, we linked information available at the time of surgery with prescription data to ascertain characteristics associated with prolonged opioid therapy. METHODS: Patients (n=6,003) with claims in the Colorado All Payer Claims Database (APCD) were matched with 20,501 encounters in a clinical database. Rates of prescription filling were defined by at least one monthly opioid claim relative to the date of surgery. Associations of variables with claims during months 2-6 post-operatively (“long-term prescription filling”) were evaluated, and significant variables were jointly modeled using binomial regression. RESULTS: Rates of patients filling opioid prescriptions preoperatively [month (M) relative to date of surgery] were 22%(-3M), 24%(-2M), and 27%(-1M); after surgery, opioid fill rates were 62%(1M), 28%(2M), 24%(3), 24%(4M), 23%(5M), and 22%(6M). The majority, 71-76%, of patients filling prescriptions in months 2-6 after surgery had also filled before surgery. In the binomial regression model, long-term opioid use was associated with prior opioid use (p

Adolescents with conduct and substance use problems are at increased risk for premature mortality, but the extent to which these risk factors reflect family- or individual-level differences and account for shared or unique variance is unknown.

Mortality hazard for clinical probands and their siblings was 4.99 times greater than that of controls (95% confidence interval = 2.40-10.40; P 0.001). After accounting for demographic characteristics, site, clinical status, familial dependence and shared contributions of CD and SUD, CD independently predicted mortality hazard, whereas SUD severity did not.In the United States, youth with conduct and substance use disorders and their siblings face far greater risk of premature death than demographically similar community controls. In contrast to substance use disorder severity, conduct disorder is a robust predictor of unique variance in all-cause mortality hazard beyond other risk factors.

Perspectives of adolescent research participants regarding conflicts of interest (COIs) and their impact on trust in researchers have not been studied. This study evaluates views of adolescent patients in treatment for substance and conduct problems compared to controls enrolled in genomic addiction research.Participants included 273 (190 patients, 83 controls) adolescents. Participants consented or assented (with parental consent) to have their genomic information deposited in a NIH biobank that shares information globally with qualified investigators. As part of that study, participants completed a COI survey. Endorsement of each COI item was analyzed with multiple logistic regressions, evaluating group, age, sex, ethnicity, and highest grade completed.Patients and controls differed in gender, ethnicity and highest grade completed. In response to the survey, 38.4% of patients and 25.3% of controls "want to know" and 35.3% of patients and 37.3% of controls "might want to know" about COIs. Males were less likely to want/might want disclosure about COIs. Older patients were more likely to want disclosure about financial interests; patients were more likely to want disclosure about possible treatments; males were more likely to want information about monetary gains. Both groups requested between 1 paragraph and 1 page of information. Disclosure of COIs did not impact trust for most participants.Adolescent patients and controls in this study want comparable information for disclosure of COIs including monetary gains, salary, publications, grants, and professional awards. Notably, the majority of patients and controls report that disclosure will not undermine trust in researchers.

Background: The immune system has a central role in controlling cancer, and factors that influence protective antitumour immunity could therefore have a significant impact on the course of malignant disease. Opioids are essential for the management of cancer pain, and preclinical studies indicate that opioids have the potential to influence these tumour immune surveillance mechanisms. The aim of this systematic literature review is to evaluate the clinical effects of opioids on the immune system of patients with cancer. Methods: A systematic search of Ovid MEDLINE (PubMed) and Embase, Cochrane database and Web of Knowledge for clinical studies, which evaluated the effects of opioids on the immune system in patients with cancer, was performed. Results: Five human studies, which have assessed the effects of opioids on the immune system in patients with cancer, were identified. Although all of these evaluated the effect of morphine on immunologic end points in patients with cancer, none measured the clinical effects. Conclusions: Evidence from preclinical, healthy volunteer and surgical models suggests that different opioids variably influence protective anti-tumour immunity; however, actual data derived from cancer populations are inconclusive and definitive recommendations cannot be made. Appropriately designed and powered studies assessing clinical outcomes of opioid use in people with cancer are therefore required to inform oncologists and others involved in cancer care about the rational use of opioids in this patient group.

Objective To describe in vitro development of human embryos derived from an individual with a homozygous pathogenic variant in NLRP7 (19q13.42) and recurrent hydatidiform mole (HM), an autosomal recessive condition thought to occur secondary to an oocyte defect. Methods A patient with five consecutive HM pregnancies was genomically evaluated via next generation sequencing followed by controlled ovarian hyperstimulation, in vitro fertilization (IVF) with intracytoplasmic sperm injection, embryo culture, and preimplantation genetic screening. Findings in NLRP7 were recorded and embryo culture and biopsy data were tabulated as a function of parental origin for any identified ploidy error. Results The patient was found to have a pathogenic variant in NLRP7 (c.2810+2T>G) in a homozygous state. Fifteen oocytes were retrieved and 10 embryos were available after fertilization via intracytoplasmic sperm injection. Developmental arrest was noted for all 10 embryos after 144 hours in culture, thus no transfer was possible. These non-viable embryos were evaluated by karyomapping and all were diploid biparental; two were euploid and eight had various aneuploidies all of maternal origin. Conclusion This is the first report of early human embryo development from a patient with any NLRP7 mutation. The pathogenic variant identified here resulted in global developmental arrest at or before blastocyst stage. Standard IVF should therefore be discouraged for such patients, who instead need to consider oocyte (or embryo) donation with IVF as preferred clinical methods to treat infertility.

We sought to identify brain activation differences in conduct-problem youth with limited prosocial emotions (LPE) compared to conduct-problem youth without LPE and community adolescents, and to test associations between brain activation and severity of callous-unemotional traits. We utilized a novel task, which asks subjects to repeatedly decide whether to accept offers where they will benefit but a beneficent other will be harmed. Behavior on this task has been previously associated with levels of prosocial emotions and severity of callous-unemotional traits, and is related to empathic concern. During fMRI acquisition, 66 male adolescents (21 conduct-problem patients with LPE, 21 without, and 24 typically-developing controls) played this novel game. Within typically-developing controls, we identified a network engaged during decision involving bilateral insula, and inferior parietal and medial frontal cortices, among other regions. Group comparisons using non-parametric (distribution-free) permutation tests demonstrated LPE patients had lower activation estimates than typically-developing adolescents in right anterior insula. Additional significant group differences emerged with our a priori parametric cluster-wise inference threshold. These results suggest measurable functional brain activation differences in conduct-problem adolescents with LPE compared to typically-developing adolescents. Such differences may underscore differential treatment needs for conduct-problem males with and without LPE.

BACKGROUND: Some conduct-disordered youths have high levels of callous unemotional traits and meet the DSM-5's "with limited prosocial emotions" (LPE) specifier. These youths often do aggressive, self-benefitting acts that cost others. We previously developed a task, the AlAn's game, which asks participants to repeatedly decide whether to accept or reject offers in which they will receive money but a planned charity donation will be reduced. In our prior work, more "costly helping" (i.e., rejecting the offered money and protecting the donation) was associated with lower callous unemotional traits. Here we extend that prior work in a larger sample of adolescent male patients with serious conduct problems and controls, and test whether this association is mediated specifically by a Moral Elevation response (i.e., a positive emotional response to another's act of virtue). METHODS: The adolescent male participants were: 45 patients (23 with LPE) and 26 controls, who underwent an extensive phenotypic assessment including a measure of Moral Elevation. About 1 week later participants played the AlAn's game. RESULTS: All AlAn's game outcomes demonstrated significant group effects: (1) money taken for self (p = 0.02); (2) money left in the charitable donation (p = 0.03); and, (3) costly helping (p = 0.047). Controls took the least money and did the most costly helping, while patients with LPE took the most money and did the least costly helping. Groups also significantly differed in post-stimulus Moral Elevation scores (p = 0.005). Exploratory analyses supported that the relationship between callous unemotional traits and costly helping on the AlAn's game may be mediated in part by differences in Moral Elevation. CONCLUSIONS: The AlAn's game provides a standardized behavioral measure associated with callous unemotional traits. Adolescents with high levels of callous unemotional traits engage in fewer costly helping behaviors, and those differences may be related to blunting of positive emotional responses. Language: en

a b s t r a c t Boys with serious conduct and substance problems (Antisocial Substance Dependence (ASD)) repeat- edly make impulsive and risky decisions in spite of possible negative consequences. Because prefrontal cortex (PFC) is involved in planning behavior in accord with prior rewards and punishments, structural abnormalities in PFC could contribute to a person's propensity to make risky decisions. Methods: We acquired high-resolution structural images of 25 male ASD patients (ages 14-18 years) and 19 controls of similar ages using a 3 T MR system. We conducted whole-brain voxel-based morphome- tric analysis (p < 0.05, corrected for multiple comparisons at whole-brain cluster-level) using Statistical Parametric Mapping version-5 and tested group differences in regional gray matter (GM) volume with analyses of covariance, adjusting for total GM volume, age, and IQ; we further adjusted between-group analyses for ADHD and depression. As secondary analyses, we tested for negative associations between GM volume and impulsivity within groups and separately, GM volume and symptom severity within patients using whole-brain regression analyses. Results: ASD boys had significantly lower GM volume than controls in left dorsolateral PFC (DLPFC), right lingual gyrus and bilateral cerebellum, and significantly higher GM volume in right precuneus. Left DLPFC GM volume showed negative association with impulsivity within controls and negative association with substance dependence severity within patients. Conclusions: ASD boys show reduced GM volumes in several regions including DLPFC, a region highly rele- vant to impulsivity, disinhibition, and decision-making, and cerebellum, a region important for behavioral regulation, while they showed increased GM in precuneus, a region associated with self-referential and self-centered thinking. © 2011 Elsevier Ireland Ltd.

U-Pb SHRIMP ages of detrital zircons from metasedimentary rocks of the Connecticut Valley-Gaspe trough in Vermont corroborate a Silurian-Devonian age of deposition for these strata and constrain their provenances. Ages of randomly selected detrital zircons obtained from quartzites within the Waits River and Gile Mountain Formations range from Archean to Devonian with Mesoproterozoic, Neopro- terozoic, Ordovician, and Silurian age populations suggesting both eastern and western sources of the sediments. The two youngest single-grain detrital zircon ages from samples collected in the Waits River Formation are 418 ± 7 and 415 ± 2 Ma. The youngest single-grain detrital zircon age from the eastern part of the Gile Mountain Formation is 411 ± 8. The youngest detrital zircons from the western portion of the Gile Mountain Formation comprise an age population with a weighted average of 409 ± 5 Ma. These ∼409 Ma zircons are likely of volcanic origin, perhaps derived from the Piscataquis magmatic belt to the east. The absence of younger volcanic zircons in the coarser-grained eastern facies of the Gile Mountain Formation suggests the eastern sediments are older and were buried during Piscataquis volcanism and deposition in the west. The shift in protoliths from calcareous silts and muds of the Waits River Formation to quartzo-feldspathic sands of the Gile Mountain Formation implies a change from a continental slope-like depositional environment to a near-shore or terrestrial environment of deposition. This change supports a transition in the nature of the basin from an intercontinental back-arc extensional setting to a foreland basin setting. Maximum depositional ages of sediments above and below this facies bound- ary constrain the timing of transition in basin style between about 415 and 411 Ma. Given the timing of the approaching Acadian wedge, this shift in basin style likely reflects westward migration of thrust sheets during the Acadian orogeny. The fine-grained nature of the youngest silts, muds and turbidites suggests that sedimentation occurred in increasingly deeper water. The implied basin subsidence was likely caused by lithospheric flexure as the Acadian wedge approached from the east. The timing of this subsidence is constrained to be younger than the youngest zircons at about 409 Ma.

Objective This study assessed whether a customized disclosure form increases understanding for adolescents with substance use disorder (SUD) when compared to a standard disclosure for genomic addiction research. Method We gathered empirical data from adolescents with SUD, family members, former patients followed since adolescence, and community counterparts. The study was conducted in four stages. Stage 1: national experts ( n = 32) identified current, future, speculative risks of broadly shared biobanks. Stage 2 assessed participants’ ( n = 181) understanding of current risks as a prerequisite for rating saliency of risks via a Visual Analog Scale. Salient risks were incorporated into a customized disclosure form. Stage 3 compared the understanding of customized disclosure by participants ( n = 165) at baseline; all groups scored comparably. Stage 4 conducted a direct comparison of the standard disclosure to standard disclosure plus customized disclosure ( n = 195). Independent t -tests compared understanding in those receiving the standard disclosure to standard disclosure plus customized disclosure within 6 groups. Results The customized disclosure significantly improved understanding in adolescent patients ( p = 0.002) and parents of patients ( p = 0.006) to the level of their counterparts. The customized disclosure also significantly improved understanding in siblings of former patients ( p = 0.034). Understanding of standard disclosure in patients versus controls was significantly different ( p = 0.005). The groups receiving the customized disclosure scored significantly higher. Understanding of the standard disclosure plus customized disclosure in patients versus controls was not significantly different. Conclusion Adolescents with addictions understand the risks of participating in genomic addiction research as well as their community counterparts when information provided is salient to them.

This study surveyed all adolescents who were enrolled in behavioral genomic research and provided DNA to a biobank, including 320 patients undergoing treatment for substance and conduct problems (SCPs) and 109 non-SCP controls. Participants selected from three options on the return of individual genomic results (RIR) and rated eight methods of re-contact. Most individuals with SCPs (77.8%) and non-SCP controls (72.5%) wanted RIR involving health or behavioral implications. The majority of individuals with SCPs (67.2%) and non-SCP controls (69.7%) indicated that phone re-contact was 'best', with e-mail (22.5% SCPs, 33.9% non-SCPs) and social networking websites (21.3% SCPs, 20.2% non-SCPs) being viable options. These results suggest a layered approach for RIR: phone calls, followed by e-mails and a secure message to a social networking account. Data from this special and vulnerable population, which includes youth involved in the criminal justice system and substantial minority participation, bring an essential and missing perspective to the discussion of RIR.

Objective Structural neuroimaging studies have demonstrated lower regional gray matter volume in adolescents with severe substance and conduct problems. These research studies, including ours, have generally focused on male-only or mixed-sex samples of adolescents with conduct and/or substance problems. Here we compare gray matter volume between female adolescents with severe substance and conduct problems and female healthy controls of similar ages. Hypotheses: Female adolescents with severe substance and conduct problems will show significantly less gray matter volume in frontal regions critical to inhibition (i.e. dorsolateral prefrontal cortex and ventrolateral prefrontal cortex), conflict processing (i.e., anterior cingulate), valuation of expected outcomes (i.e., medial orbitofrontal cortex) and the dopamine reward system (i.e. striatum). Methods We conducted whole-brain voxel-based morphometric comparison of structural MR images of 22 patients (14-18 years) with severe substance and conduct problems and 21 controls of similar age using statistical parametric mapping (SPM) and voxel-based morphometric (VBM8) toolbox. We tested group differences in regional gray matter volume with analyses of covariance, adjusting for age and IQ at p

BackgroundAccidental injury and homicide, relatively common among adolescents, often follow risky behaviors; those are done more by boys and by adolescents with greater behavioral disinhibition (BD).HypothesisNeural processing during adolescents' risky decision-making will differ in youths with greater BD severity, and in males vs. females, both before cautious behaviors and before risky behaviors.Methodology/principal findings81 adolescents (PATIENTS with substance and conduct problems, and comparison youths (Comparisons)), assessed in a 2 x 2 design (PatientsComparisons x Male:Female) repeatedly decided between doing a cautious behavior that earned 1 cent, or a risky one that either won 5 or lost 10 cents. Odds of winning after risky responses gradually decreased. Functional magnetic resonance imaging captured brain activity during 4-sec deliberation periods preceding responses. Most neural activation appeared in known decision-making structures. PATIENTS, who had more severe BD scores and clinical problems than Comparisons, also had extensive neural hypoactivity. Comparisons' greater activation before cautious responses included frontal pole, medial prefrontal cortex, striatum, and other regions; and before risky responses, insula, temporal, and parietal regions. Males made more risky and fewer cautious responses than females, but before cautious responses males activated numerous regions more than females. Before risky behaviors female-greater activation was more posterior, and male-greater more anterior.Conclusions/significanceNeural processing differences during risky-cautious decision-making may underlie group differences in adolescents' substance-related and antisocial risk-taking. Patients reported harmful real-life decisions and showed extensive neural hypoactivity during risky-or-cautious decision-making. Males made more risky responses than females; apparently biased toward risky decisions, males (compared with females) utilized many more neural resources to make and maintain cautious decisions, indicating an important risk-related brain sexual dimorphism. The results suggest new possibilities for prevention and management of excessive, dangerous adolescent risk-taking.

Adolescents with substance use disorder (SUD) and conduct problems exhibit high levels of impulsivity and poor self-control. Limited work to date tests for brain cortical thickness differences in these youths.To investigate differences in cortical thickness between adolescents with substance use and conduct problems and controls.We recruited 25 male adolescents with SUD, and 19 male adolescent controls, and completed structural 3T magnetic resonance brain imaging. Using the surface-based morphometry software FreeSurfer, we completed region-of-interest (ROI) analyses for group cortical thickness differences in left, and separately right, inferior frontal gyrus (IFG), orbitofrontal cortex (OFC) and insula. Using FreeSurfer, we completed whole-cerebrum analyses of group differences in cortical thickness.Versus controls, the SUD group showed no cortical thickness differences in ROI analyses. Controlling for age and IQ, no regions with cortical thickness differences were found using whole-cerebrum analyses (though secondary analyses co-varying IQ and whole-cerebrum cortical thickness yielded a between-group cortical thickness difference in the left posterior cingulate/precuneus). Secondary findings showed that the SUD group, relative to controls, demonstrated significantly less rightleft asymmetry in IFG, had weaker insular-to-whole-cerebrum cortical thickness correlations, and showed a positive association between conduct disorder symptom count and cortical thickness in a superior temporal gyrus cluster.Functional group differences may reflect a more nuanced cortical morphometric difference than ROI cortical thickness. Further investigation of morphometric differences is needed. If replicable findings can be established, they may aid in developing improved diagnostic or more targeted treatment approaches.

Holographic polymerization (H-P) has been used to fabricate polymer-dispersed liquid crystals and pattern inert nanoparticles. In this article, one-dimensional grating structures of Norland resin and polyethylene glycol (PEG) were achieved using the H-P technique. Both reflection and transmission grating structures were fabricated. The optical properties of the reflection grating structures (also known as Bragg reflectors, BRs) are thermosensitive, which is attributed to the formation and crystallization of PEG crystals. The thermal switching temperature of the BR can be tuned by using different molecular weight PEG samples. The hierarchical structure and morphology of the BR were studied using synchrotron X-ray, polarized light microscopy and transmission electron microscopy. PEG crystals were found to be confined in w60 nm thick layers in the BR. Upon crystallization, the PEG lamellae were parallel to the BR surfaces and PEG chains were parallel to the BR normal, resembling the confinedcrystallizationbehaviorofpolyethylene oxide(PEO)inPEO-block-polystyrene (PEO-b-PS)blockcopolymers.Thisobservation suggests that the tethering effect in the block copolymer systems does not play a major role in PEG chain orientation in the confined nanoenvironment. 2006 Elsevier Ltd.

The Levi Jordan plantation house is one of the few antebellum plantation structures to have survived in Brazoria County. It is the only standing structure associated with the plantation, which began operating in 1848 and was occupied continually up through the 1990s. The original house, built in the early 1850s using slave labor, was a 20x60-ft two-story wooden frame structure. It was altered many times during its long occupation, often due to hurricane damage. A portion of the Levi Jordan Plantation was acquired by the State of Texas in 2002 and managed by the Texas Parks and Wildlife Department until 2008, when the Texas Historical Commission took over its management. By then, the 160-year-old plantation house had suffered greatly and was in bad condition. The Texas Historical Commission began plans to stabilize and restore the historic house. Prewitt and Associates archeologists were contracted to conduct the archeological investigations associated with this work. The stabilization project included the permanent removal of the twentieth-century additions, hydraulic lifting of the antebellum house, removal of the original foundation piers, and installation of a new concrete perimeter foundation. The two original brick chimneys were removed and reconstructed. The investigations, conducted in 2010 and 2011, documented the following features: 2 cisterns, 2 chimney footings and 39 foundation piers associated with the plantation house; a chimney footing associated with an east wing behind the house; a chimney foundation associated with a former detached kitchen behind the main house; a brick patio and walkway associated with the original house; two large brick rubble concentrations and a small brick cluster; and a possible rain barrel brick pad. Other features examined were 15 possible piers that may be associated with the original house, the original east wing, a possible west wing, a south porch, a west porch, and an east porch. The archeological investigations revealed many details about the architecture of the original plantation house and subsequent additions. The evidence provides a better understanding of the building construction sequence and insights into the complex evolution of the Levi Jordan plantation house over its ca. 160-year existence. The most significant find is an 1853 gold coin found in the brick pad at the bottom of the southeast corner pier. This is almost certainly a date coin that was placed in this location by Levi Jordan or a master builder in a cornerstone foundation rite, and it provides an accurate date for the beginning of the house construction.

Aims:Alcohol, druguse, andweaponcarryingare apublichealth concern especially among students because they can have deleterious effects on physical and mental health. This study determined the prevalence of and gender specific factors associated with these behaviors among Thai adolescent students. Methods: A cross-sectional study in high school and vocational school in Bangkok, Thailand was conducted in 2014. Self-administrated questionnaires assessed past 30 day behaviors among students between 11 and 18 years of age (2561 students from 26 schools). Results:Overall, one fourth (24.4%) of students reported past 30 day alcohol use, 2.5% reported drug use, and 7.8% reported weapon carrying. Older youth were more likely to report drinking than those younger (p< .0001). Multivariate logistic regression analyses showed that alcohol use was almost four times higher among drug users than nondrug users (OR 3.93). Students who carried a weapon had nearly three times the risk of drinking than their counterparts (OR 2.74). Overall, females who used drugs or who carried a weapon were 7.94 and 3.15 times respectively to report drinking compared to males. All other factors adjusted for were also more strongly associated with drinking among females than males; factors include number of friends who smoke (OR 2.66 vs OR 1.77), weight issues (OR 2.10), smoking (OR 5.36 vs OR 4.59), and energy drink use (OR 3.41 vs OR 2.04). Conclusions: An increased association of drug use and weapon carrying with alcohol use was found for adolescent females in Thailand. Findings indicate gender specific interventions are needed for adolescents for these behaviors.

An evolutionarily nonconserved region of approximately 250 amino acids can be deleted from the amino-terminal part of the beta subunit of Escherichia coli RNA polymerase without effect on the enzyme's basic function. The non-essential segment is located between two highly conserved motifs and is flanked by sequences participating in the rifampicin-binding site. The results define the second non-essential domain in the beta subunit, in addition to the more distal dispensable segment identified previously. The Alc protein of bacteriophage T4 participates in the host transcription shutoff after infection by causing premature termination of transcription on E. coli DNA. Point mutations which prevent Alc action in vivo change amino acids in the non-essential NH2-terminal domain of the beta subunit. These point mutations as well as deletions which remove the non-essential region also prevent Alc action. Thus, in the RNA polymerase molecule, the proximal non-essential domain of beta may function as an acceptor of Alc or other regulatory factors.

This preliminary report describes historical research and an intensive archeological survey conducted for a 4.9-mile-long stretch of FM 2092 in Menard County by Prewitt and Associates, Inc. The work was performed for the Texas Department of Transportation in conjunction with a road improvement project beginning at the eastern Menard city limit and extending eastward to just beyond Fivemile Crossing. Crossing over Pleistocene and Holocene alluvial terraces of the San Saba River, the project area is located in a high-probability area for buried prehistoric sites and has a dynamic history of intensive use since Spanish colonial times. Investigations included geoarcheological mapping, historic research and evaluation, pedestrian survey, backhoe and gradall trenching, mechanical auger testing, and shovel testing. Archeological remains of 10 previously recorded sites and 9 newly discovered sites were documented within the FM 2092 right of way. Of these 19 sites, 6 have prehistoric components, 4 have historic components, and 9 have both prehistoric and historic components. At 14 of the 15 sites with prehistoric components, either no prehistoric remains were found within the right of way or the prehistoric remains are very low density and extensively disturbed. No prehistoric features were encountered at any of these 14 sites. The prehistoric components at these 14 sites (41MN5, 41MN9, 41MN11, 41MN12, 41MN15, 41MN23, 41MN53, 41MN54, and 41MN56–61) were recommended as not eligible for listing in the National Register, while the portion of 41MN55 inside the right of way was recommended as eligible. Site 41MN55 was subsequently tested, and the results of this work are reported separately. At 11 of the 13 sites with historic components, either no historic remains were found within the right of way or historic remains were limited to nondiagnostic artifacts (i.e., that could date to the late nineteenth or early twentieth centuries) in disturbed contexts. Although intact deposits and historic features associated with these sites may be present outside the right of way, none were observed in the right of way. It was recommended that these 11 sites (41MN5, 41MN9, 41MN10, 41MN12, 41MN13, 41MN15, 41MN20, 41MN53, 41MN54, 41MN60, and 41MN61) are not eligible for listing in the National Register. During this survey, hand and mechanical excavations were conducted at 41MN23, the site of the historic Mission San Sabá. The portion of the site within the FM 2092 right of way was recommended as eligible for listing in the National Register. Intensive data recovery excavations were subsequently conducted, but these investigations are reported separately. Site 41MN21 is the Menard Irrigation Company canal and associated smaller lateral ditches that comprise the entire irrigation system. Historical research documents that construction of this canal system started in 1874 and expanded in the late 1800s. The system is still used for agricultural irrigation today. Portions of the irrigation system crossing the FM 2092 right of way were documented. The system is probably eligible for listing in the National Register, but the irrigation system will not be impacted by this road project, and no further work is recommended.

Aims: Abused drugs activate dopaminergic (DA) “reward” regions (dorsal and ventral striatum, midbrain), promoting further drug-taking. While adverse effects lead most adolescents to limit risky drug use, some with genetic vulnerabilities to substance use disorders (SUD) and conduct problems, undeterred by risks, press on, developing SUD. We asked: (1) is the enhanced vulnerability of those youths mediated by excess reward-system activity, or by deficient inhibition of risky behaviors; (2) do those mechanisms differ by gender? Methods: Our fMRI analyses of 41 adolescent patients with severe SUD and conduct problems (20 males) and 40 comparison youths (20 males) continue. In each of 90 risky-decision trials youths decided between pressing a cautious button to earn 1 cent, or a risky one that either won 5 or lost 10 cents. Riskypress “win” odds gradually fell from 0.78 to 0.22. We analyzed brain activity during 4-sec pre-response deliberations with voxel-level and cluster-level FWE correction before risky, and separately before cautious, presses. Results: Making cautious responses required inhibiting the more-rewarded risky ones; to do so, bothmale and female comparison youths significantly activated frontopolar, temporal, parietal, or cerebellar regions, or DLPFC, more than patients; the regions differed by gender. No group activated DA regions before cautious responses. Before risky responses all four groups showed reward anticipation, activating DA regions. Comparison boys activatedmanymore, andcomparisongirlsmany fewer,DAvoxels than patients, but those differences were not statistically significant. Conclusions: Patients’ DA regions did not differ significantly from comparison youths’ at the power available here. Before cautious responses comparison youths more than patients activated other regions that may sustain cautious decisions despite temptations (e.g., drug availability, peer pressure). Those control-related regions may underlie patients’ and healthy youths’ differing vulnerabilities to SUD. Financial support: NIDA DA 011015; Kane Family Foundation.

This document constitutes the final report of work done by Prewitt and Associates, Inc. (PAI), under a contract from the Texas Department of Transportation (TxDOT) to provide archeological services in four TxDOT districts—Abilene, Brownwood, Fort Worth, and Waco. Under this contract, PAI completed Impact Evaluations and Surveys to assist TxDOT in meeting the requirements of their Memorandum of Understanding with the Texas Historical Commission and a Programmatic Agreement between the Advisory Council on Historic Preservation, the Federal Highway Administration, the Texas Historical Commission, and TxDOT. The contract began on 26 September 2003. A total of 77 projects were conducted. The 77 projects consisted of 25 Impact Evaluations and 52 Surveys. Combined, these entailed efforts at 52 bridge replacements, 14 road realignment or widening projects (many also involving bridge replacements), 1 new road construction project, 1 hike-and-bike trail construction project, 5 projects involving upgrading or replacing existing culverts, 1 project involving construction of drainage improvements, 2 unspecified road maintenance or improvement projects, and 1 project involving replacement of an interstate highway interchange. Of the 25 Impact Evaluations done, 8 led to recommendations that survey could be needed before construction. In 4 cases, the need for survey depended on whether new right of way would be acquired, which was unknown when the Impact Evaluations were done. The other 17 Impact Evaluations resulted in recommendations that no survey be required before construction based on the limited potential for sites with good integrity. Of the 52 Surveys done under this contract, 9 investigated six newly recorded and four previously recorded sites; eight of the sites are prehistoric, and two are of historic age. Four prehistoric sites were recommended for testing to assess eligibility for listing in the National Register of Historic Places and designation as State Archeological Landmarks, and one historic site was recommended for archival and oral history research. The other 43 Surveys did not find any archeological sites. All artifacts collected and records generated by projects done under this contract are curated at the Texas Archeological Research Laboratory (TARL), The University of Texas at Austin. Artifacts were collected from five sites (41BQ285, 41CV1636, 41HM53, 41LT307, and 41SV4). Those from 41HM53 and 41SV4 are from State-owned lands and thus are curated in a held-in-trust status at TARL. The artifacts from 41BQ285, 41CV1636, and 41LT307 are from private lands and are curated in a non-held-in-trust status.

During May-July 1999, personnel from Prewitt and Associates, Inc., conducted a re-location survey of 44 previously recorded sites at Waco Lake in McLennan County, Texas. The U.S. Army Corps of Engineers, Fort Worth District, sponsored the project as a result of proposed plans to raise the conservation pool level of the lake by 7 ft. The purposes of the study were to re-locate the 44 sites and assess their current conditions, to rerecord them, and to reassess the eligibility of each site for listing in the National Register of Historic Places. Two sites with prehistoric components are recommended as being eligible for listing in the National Register, while 14 are considered ineligible: The remaining 14 sites with prehistoric components are of unknown eligibility, with additional testing required before a determination can be made. Seven of these sites appear to be the best candidates for further work based on their elevations and the impacts anticipated as a result of raising the lake level. Four sites with historic components are of unknown eligibility, pending additional field investigations and/or archival research; 2 of these appear to be the best candidates for further work based on their elevations and the anticipated impacts. The remaining 12 sites with historic components are considered ineligible for the National Register.

Channelized receivers are useful in communications systems that use frequency division multiplexing, and in wideband radar and electronic warfare receivers. In present wideband communications equipment, the channelization function is done typically with discrete elements such as mixers and surface acoustic wave (SAW) bandpass filters on a single channel basis. Recently much activity has been directed to using digital techniques and devices to make smaller, cheaper receivers. Following this trend, this paper exploits the 'Timeline' 0.18 micron CMOS technology recently announced by Texas Instruments and show the bandwidths, levels of system integration, and package sizes that become possible with the Timeline technology. The design example shown is a digital channelizer for a system with 150 MHz total bandwidth including 60 channels on 2.5 MHz channel centers. A polyphase filter bank algorithm with 6x oversampling compared to the channel spacing is used. The design is suitable for a burst communication receiver. With the Timeline technology, an ASIC that implements two maximally decimated filter banks at the above bandwidths is shown. The ASIC fits onto a 20 mm by 20 mm die and consumes about 7 watts. Three such ASICs are then needed to implement the complete 6x oversampled filter bank, which will output 60 complex channels at 15 MSPS for about 20 watts.
