22Q11 deletion syndrome , *EMOTIONS , *NEUROBEHAVIORAL disorders , *SYNDROMES , *PHENOTYPES , *APATHY , *SELF-reliance - Abstract
The presentation of neurogenetic disorders such as 22q11.2 Deletion Syndrome (22q11.2DS) includes broad neuropsychiatric phenotypes that impact functioning and require assessment and treatment. Like in non-syndromal neuropsychiatric disorders, there is heterogeneity in symptom severity and illness course. The study of risk and resilience in the general population has benefited from measurement tools that parse heterogeneity and guide treatment. Suitability of such tools in neurogenetic disorders has not been examined and is essential to establish as prerequisite for examining whether similar processes modulate psychopathology in these populations. We applied the Risk & Resilience Battery assessing intrapersonal, interpersonal, and environmental domains, to 80 patients with 22q11.2DS, 30 from Philadelphia, USA and 50 from Tel-Aviv, Israel. We also evaluated global functioning and obtained self-reports of anxiety and depression. We examined the Risk & Resilience Battery reliability for each factor and used partial correlations to examine relations between the Risk & Resilience Battery factors and clinical measures. Across samples, items within each risk and resilience factor showed good to excellent internal consistency. Higher scores on peer victimization, emotion dysregulation, and hostile close relationships were related to reports of anxiety and depression. Higher levels of self-reliance related to lower anxiety while greater security in close relationships related to lower depression. The Risk & Resilience Battery can be applied to 22q11.2DS samples and advance Gene X Environment research and interventions. • Risk and Resilience factors in the general population are similarly prominent in a neurogenetic syndrome. • These Risk and Resilience factors modulate symptom severity and functioning in a neurogenetic syndrome. • The Risk and Resilience measures can be reliably applied across international sites.

Predator–prey interactions present heightened opportunities for pathogen spillover, as predators are at risk of exposure to infectious agents harbored by prey. Epizootics with high morbidity and mortality have been recorded following prey-to-predator spillover events, which have had significant conservation implications for sensitive species. Using felids as a detailed case study, we have documented both virulent and clinically silent infections in apex predators following transfer of microbes from prey. We draw on these examples and others to examine the mechanisms that determine frequency and outcome of predator exposure to prey-based pathogens. We propose that predator–prey dynamics should be more thoroughly considered in empirical research and disease dynamic modeling approaches in order to reveal answers to outstanding questions relating to pathogen bioaccumulation. Advances in pathogen detection technologies have allowed more thorough characterization of infections in free-ranging wildlife. In well-studied predators like Puma concolor , multiple occurrences of spillover following consumption of reservoir hosts as prey have been observed. Outcomes of predator exposures to infectious agents harbored by prey vary, but rarely result in widespread disease. Models of disease transmission have largely considered predator behavior in the context of effects in the prey species, versus consequences to the predator. However, certain prey-transmitted infections can result in high mortality rates, sometimes with significant negative impacts on conservation of vulnerable/threatened species. [ABSTRACT FROM AUTHOR]

ECOSYSTEM services , *ECOSYSTEMS , *PATHOGENIC microorganisms , *ENVIRONMENTAL policy , *AUTOTROPHS , *ALGAE - Abstract
Despite the ubiquity of pathogens in ecological systems, their roles in influencing ecosystem services are often overlooked. Pathogens that infect primary producers (i.e., plants, algae, cyanobacteria) can have particularly strong effects because autotrophs are responsible for a wide range of provisioning, regulating, and cultural services. We review the roles of pathogens in mediating ecosystem services provided by autotrophs and outline scenarios in which infection may lead to unexpected outcomes in response to global change. Our synthesis highlights a deficit of information on this topic, and we outline a vision for future research that includes integrative theory and cross-system empirical studies. Ultimately, knowledge about the mediating roles of pathogens on ecosystem services should inform environmental policy and practice. Pathogens are ubiquitous in nature, and they can play crucial roles in ecosystem processes. Pathogens mediate many ecosystem services on which humans rely. Pathogens that infect autotrophs (e.g., plants, algae, and cyanobacteria) may be especially important to human well-being because these hosts are fundamental to ecosystem function. While infectious disease is inherently negative from the perspective of infected hosts, pathogens infecting autotrophs can have positive or negative effects on ecosystem services. Global change induces shifts in pathogen prevalence and disease severity, which may lead to unexpected outcomes for ecosystem services. Understanding how pathogens impact ecosystem services can fundamentally improve our ability to make environmental decisions for a sustainable future. [ABSTRACT FROM AUTHOR]

FUNCTIONAL magnetic resonance imaging , *ANXIETY treatment - Abstract
Objective: Although behaviorally inhibited (BI) temperament predicts risk for anxiety, anxiety in BI may involve distinct neural responses to errors. The current study examines the relations between anxiety and neural correlates of error processing both in youths identified as BI in early childhood and in youths seeking treatment for an anxiety disorder.Method: All participants underwent functional magnetic resonance imaging using a flanker task to assess responses to errors. A study in healthy subjects assessed test-retest reliability to inform analyses in two other samples. For one sample, a cohort of BI youths (Low BI, n = 28; High BI, n = 27) was followed into adolescence. For the other, participants were recruited based on the presence or absence of an anxiety disorder. Using identical methods in medication-free subjects, analyses compared relations between anxiety and error processing across the two samples.Results: Error-processing exhibited acceptable reliability. Within a ventromedial-prefrontal-cortex (vmPFC) cluster, anxiety related to error processing only in youths whose early-life BI status was known. In the high BI group, anxiety related to reduced neural response to errors. No such associations manifested in treatment-seeking youths. Other analyses mapped relations between error-processing and anxiety in each sample on its own. However, only the vmPFC cluster statistically differentiated the neural correlates of anxiety in BI.Conclusion: BI temperament may define a unique pathway into anxiety involving perturbed neural responding to errors. Although BI is a risk factor for later anxiety, the neural and associated features of anxiety in BI youths may differ from those in treatment-seeking youths. [ABSTRACT FROM AUTHOR]- Published

• Carrot Rewards is a free, incentive-based, smartphone health app available in participating Canadian provinces. • An in-app quiz educated users about the importance of the influenza vaccine and promoted pharmacy influenza clinics. • The app used novel "push" notifications when the user was within 200 m of the sponsored pharmacy. • The quiz completion rate was high although only a small number visited the pharmacy. • Loyalty point incentives did not appear to influence pharmacy visits. Carrot Rewards is a free, incentive-based, smartphone health app available in participating provinces in Canada. One feature of Carrot was designed to incentivize influenza vaccine education messages and encourage vaccine uptake for users in the province of British Columbia. This study aimed to evaluate the uptake of the Carrot Flu Campaign educational quiz and to determine if mobile "push" notifications, plus loyalty point incentives, resulted in users visiting a sponsored pharmacy to discuss and receive the influenza vaccine. The Carrot Flu Campaign delivered an in-app quiz, educating users on the importance of the influenza vaccine. Push notifications were then sent to users when they came within 200 m of a sponsored pharmacy. Those who visited the pharmacy collected bonus points and completed a follow up quiz tracking influenza vaccine behaviour. A sub-sample of users completed the Flu Campaign between their baseline and follow up Health Risk Assessment (HRA), a survey which asked about influenza vaccine uptake behaviour. Descriptive statistics were summarized. A total of 38.1% (30,538/80,228) registered Carrot users completed the Flu Campaign quiz. Of those in participating cities (n = 21,469), 41% clicked on the map to show the nearest sponsored pharmacy and 78% enabled their smartphone's "locations" feature, allowing them to receive the push notifications. A small number of users spoke to a pharmacist (n = 96) and less than half reported receiving the influenza vaccine (38/96; 39.6%). From the HRA sub-sample (n = 3693), approximately 5% more users reported receiving the influenza vaccine during the 2017 influenza season compared to the previous year. Carrot Rewards used a novel delivery method to educate the general population and showed geolocation could be used to facilitate influenza vaccine uptake. Future iterations could tailor content to target those most at risk and should consider more robust evaluation methods to determine the app's effectiveness. [ABSTRACT FROM AUTHOR]

Bhatt, Sudhir, Mehta, Poonam, Chen, Chen, Schneider, Christina L., White, Lauren N., Chen, Hai-Lan, and Kong, Michael G.
- Abstract
Background and Aims It has been increasingly recognized that the safety of GI endoscopes needs to be improved by addressing the small margin of safety of high-level disinfectants (HLDs) and the failure of HLDs to clear multidrug-resistant organisms and biofilms. There is also an unmet need for effective low-temperature sterilization techniques that have a clear pathway for U.S. Food and Drug Administration clearance. Here, we report the results of our investigation of a novel argon plasma-activated gas (PAG) for disinfection and potentially sterilization of biofilm-contaminated endoscopic channels. Methods Test polytetrafluoroethylene channel segments were contaminated with 4-, 24- and 48-hour luminal biofilms of methicillin-resistant Staphylococcus aureus , Pseudomonas aeruginosa, or Escherichia coli and were treated by PAG flowing for up to 9 minutes. After PAG treatment, inactivation and dispersal of luminal bacterial biofilms and their regrowth in 48 hours were evaluated. Reactive species induced by PAG were measured with colorimetric probes and electron spin resonance spectrometry. Surface morphology and elemental composition of PAG-treated channel material were analyzed with scanning electron microscopy. Results PAG treatment for 9 minutes led to more than 8 log reduction of viable cells and dispersal of 24- and 48-hour luminal biofilms of all 3 bacteria and to suppression of their regrowth, whereas it resulted in little morphologic abnormalities in channel material. Ozone concentration of PAG fell to below.01 ppm within 30 seconds of switching off the plasma. PAG-treated deionized water was acidified with numerous types of reactive species, each with a concentration some 3 orders of magnitude or more below its bacterial inhibition concentration. Conclusions PAG is capable of effectively and rapidly disinfecting luminal bacterial biofilms and offers an alternative to the step of HLDs and/or ethylene oxide in the endoscope reprocessing procedure with safety to personnel and environment.

- Abstract
Face emotion imaging paradigms are widely used in both healthy and psychiatric populations. Here, in children and adolescents, we evaluate the test-retest reliability of blood oxygenation-level dependent (BOLD) activation and task-based functional connectivity on a widely used implicit face emotion processing task (i.e., gender labeling). Twenty-five healthy youth ( M age = 13.97 year s; 60% female) completed two functional magnetic resonance imaging (fMRI) scan sessions approximately two months apart. Participants identified the gender of faces displaying angry, fearful, happy, and neutral emotions. A Bayesian adaptation of the intraclass correlation (ICC) assessed reliability of evoked BOLD activation and amygdala seed-based functional connectivity on task events vs. baseline as well as contrasts between face emotions. For each face emotion vs. baseline, good reliability of activation was demonstrated across key emotion processing regions including middle, medial, and inferior frontal gyri. However, contrasts between face emotions yielded variable results. Contrasts of angry to neutral or happy faces exhibited good reliability of amygdala connectivity to prefrontal regions. Contrasts of fearful to happy faces exhibited good reliability of activation in the anterior cingulate. Findings inform the reproducibility literature and emphasize the need for continued evaluation of task reliability. [ABSTRACT FROM AUTHOR]

Reintroduction programs aim to restore self-sustaining populations of threatened species to their historic range. However, demographic restoration may not reflect genetic restoration, which is necessary for the long-term persistence of populations. Four threatened Australian mammals, the greater stick-nest rat ( Leporillus conditor ), greater bilby ( Macrotis lagotis ), burrowing bettong ( Bettongia lesueur ) and western barred bandicoot ( Perameles bougainville ), were reintroduced at Arid Recovery Reserve in northern South Australia over the last 18 years. These reintroductions have been deemed successful based on population growth and persistence, however the genetic consequences of the reintroductions are not known. We generated large single nucleotide polymorphism (SNP) datasets for each species currently at Arid Recovery and compared them to samples collected from founders. We found that average genetic diversity in all populations at the Arid Recovery Reserve are close to, or exceeding, the levels measured in the founders. Increased genetic diversity in two species was achieved by admixing slightly diverged and inbred source populations. Our results suggest that genetic diversity in translocated populations can be improved or maintained over relatively long time frames, even in small conservation reserves, and highlight the power of admixture as a tool for conservation management.

Anxiety disorders are the most common mental health disorder. Therefore, elucidating brain mechanisms implicated in anxiety disorders is important avenue for developing novel treatments and improving care. The dorsolateral prefrontal cortex (dlPFC) is thought to be critically involved in working memory processes (i.e. maintenance, manipulation, suppression, etc.). In addition, there is evidence that this region is involved in anxiety regulation. However, it is unclear how working memory related dlPFC processes contribute to anxiety regulation. Furthermore, we know that laterality plays an important role in working memory related dlPFC processing, however there is no current model of dlPFC mediated anxiety regulation that accounts for potential laterality effects. To address this gap, we propose a potential framework where the dlPFC contributes to emotion regulation via working memory processing. According to this framework, working memory is a fundamental process executed by the dlPFC. However, the domain of content differs across the left and right dlPFC, with the left dlPFC sensitive to primarily verbal content, and the right dlPFC sensitive to primarily non-verbal (affective content). Critically, working memory processes allow for both the retention and suppression of affective information in working memory and the overall net effect of processing on mood will depend on the balance of retention and suppression, the valence of the information being processed (positive vs. negative), and the domain of the information (verbal vs. non-verbal). If accurate, the proposed framework predicts that effects of neuromodulation targeting the dlPFC may be dependent upon the context during which the stimulation is presented. This article is part of the Special Issue on 'Fear, Anxiety and PTSD'. • We propose a model relating dlPFC-mediated emotion regulation to working memory. • We argue that working memory is the fundamental process executed by the dlPFC. • We argue that only the content domain differs across the left and right dlPFC. • Left dlPFC can maintain or suppress verbal content in working memory. • Right dlPFC can maintain or suppress non-verbal content in working memory.

Abstract: Objective: To determine incidence and etiologies of craniofacial injuries in the pediatric population through comparison of injuries caused by all-terrain vehicles and golf cart trauma. Study design: Case series with chart review. Setting: Level 1 trauma center. Subjects and methods: Retrospective review of pediatric traumas at a tertiary academic medical center from 2003 to 2012 identified 196 patients whose injuries resulted from accidents involving either all-terrain vehicles or golf carts. Data was collected and variables such as age, gender, driver vs. passenger, location of accident, Glasgow coma scale, Injury severity scale, Abbreviated injury scale, and presence or absence of helmet use were examined. Results: 196 pediatric patients were identified: 68 patients had injuries resulting from golf cart accidents, and 128 patients from ATV accidents. 66.4% of ATV-related traumas were male, compared to 52.9% of golf cart-related traumas. Ages of injured patients were similar between the two modalities with average age of ATV traumas 10.8 (±4.0) years and golf cart traumas 10.0 (±4.6) years. Caucasians were most commonly involved in both ATV (79.7%) and golf cart traumas (85.3%). 58.6% of all ATV related trauma and 69.1% of all golf cart trauma resulted in craniofacial injuries. The most common craniofacial injury was a closed head injury with brief loss of consciousness, occurring in 46.1% of the ATV traumas and 54.4% of the golf cart traumas. Temporal bone fractures were the second most common type of craniofacial injury, occurring in 5.5% of ATV accidents and 7.4% of the golf cart traumas. Length of hospital stay and, cases requiring surgery and severity scores were similar between both populations. Intensive care admissions and injury severity scores approached but not reach statistical significance (0.096 and 0.083, respectively). The only statistically significant differences between the two modalities were helmet use (P =0.00018%) and days requiring ventilator assistance (P =0.025). Conclusions: ATVs and golf carts are often exempt from the safety features and regulations required of motor vehicles, and ATV and golf cart accidents represent a significant portion of pediatric traumas. This study found that ATV and golf cart accidents contribute significantly to craniofacial trauma requiring hospitalization, with resultant morbidity and mortality. Further investigation of these injuries and their prevention in the pediatric population is needed before efforts to promote effective safety regulations for such vehicles in the future can be addressed.

Abstract: Both attention bias to threat and negative interpretive bias have been implicated in the emergence and maintenance of anxiety disorders. However, relations between attention and interpretive biases remain poorly understood. The current study experimentally manipulated attention bias to threat and examined the effects of attention training on the way ambiguous information was interpreted. Results suggest that the preferential allocation of attention towards threat affects the manner in which ambiguous information is interpreted. Individuals trained to attend to threat were more likely than individuals in a placebo training group to interpret ambiguous information in a threat-related manner. These data suggest that perturbations in the initial stages of information processing associated with anxiety may lead to a cascade of subsequent processing biases. [Copyright &y& Elsevier]

• Food advertising regulation a contentious policy issue. • Framing strategies used by policy actors important to capture for policy analysis. • Policy actors use different moral frameworks to support or oppose policies. • Tension between children's rights and industry rights moral frameworks identified. Exposure to advertising of food and beverages high in fat sugar and salt (HFSS) is considered a factor in the development of childhood obesity. This paper uses framing analysis to examine the strategic discursive practices employed by non-industry and industry responders to the Committee of Advertising Practice's consultation responses (n = 86) on UK regulation of non-broadcast advertising of foods and soft drinks to children. Our analysis demonstrates non-industry and industry responders engaged in a moral framing battle centred on whose rights were deemed as being of greatest importance to protect: children or industry. Both industry and non-industry responders acknowledged that childhood obesity and non-broadcast advertising were complex issues but diverged on how they morally framed their arguments. Non-industry responders employed a moral framework that aligned with the values represented in social justice approaches to public health policy, where children were identified as vulnerable, in need of protection from harmful HFSS product advertising and childhood obesity was a societal problem to solve. In contrast, industry responders emphasised industry rights, portraying themselves as a responsible industry that is victim to perceived disproportionate policymaking, and values more closely aligned with a market justice approach to public health policy. Our analysis provides detailed insights into the framing strategies used in the policy debate surrounding the non-broadcast advertising of HFSS foods to children. This has relevance as to how advocacy organisations can develop counter-framing to industry frames which seek to limit effective regulation. [ABSTRACT FROM AUTHOR]

Abstract: Anxious individuals show an attention bias towards threatening information. However, under conditions of sustained environmental threat this otherwise-present attention bias disappears. It remains unclear whether this suppression of attention bias can be caused by a transient activation of the fear system. In the present experiment, high socially anxious and low socially anxious individuals (HSA group, n=12; LSA group, n=12) performed a modified dot-probe task in which they were shown either a neutral or socially threatening prime word prior to each trial. EEG was collected and ERP components to the prime and faces displays were computed. HSA individuals showed an attention bias to threat after a neutral prime, but no attention bias after a threatening prime, demonstrating that suppression of attention bias can occur after a transient activation of the fear system. LSA individuals showed an opposite pattern: no evidence of a bias to threat with neutral primes but induction of an attention bias to threat following threatening primes. ERP results suggested differential processing of the prime and faces displays by HSA and LSA individuals. However, no group by prime interaction was found for any of ERP components.

- Abstract
The field of thyroid surgery has evolved to the point where multiple access options are now available. These include conventional approaches, minimally invasive endoscopic and non-endoscopic methods, and even remote access techniques with or without robotic assistance. Remote access surgery is reserved for those individuals who are committed to completely eliminating a neck scar. The procedures require more extensive dissection and robotic technology facilitates their performance. While an axillary approach has been the most commonly pursued, we have developed an easier technique that puts fewer structures at risk and involves a reduced area of dissection. It uses as its access portal a modified facelift incision. [Copyright &y& Elsevier]

OCEAN acidification ,FOOD preferences ,OCEAN energy resources ,EXCRETION - Abstract
In this study, we assessed the Atlantic surfclam (Spisula solidissima) energy budget under different ocean acidification conditions (OA). During 12 weeks, 126 individuals were maintained at three different ρCO 2 concentrations. Every two weeks, individuals were sampled for physiological measurements and scope for growth (SFG). In the high ρCO 2 treatment, clearance rate decreased and excretion rate increased relative to the low ρCO 2 treatment, resulting in reduced SFG. Moreover, oxygen:nitrogen (O:N) excretion ratio dropped, suggesting that a switch in metabolic strategy occurred. The medium ρCO 2 treatment had no significant effects upon SFG; however, metabolic loss increased, suggesting a rise in energy expenditure. In addition, a significant increase in food selection efficiency was observed in the medium treatment, which could be a compensatory reaction to the metabolic over-costs. Results showed that surfclams are particularly sensitive to OA; however, the different compensatory mechanisms observed indicate that they are capable of some temporary resilience. • Surfclam energy budget is decreased by high ρCO2 concentration. • High ρCO 2 concentration affects negatively surfclam clearance rate. • Surfclams adopt different metabolic strategies facing ocean acidification. • Metabolic loss rises after a moderate ρCO2 concentration increase.

Objective: Deficits in executive function (EF) are common in neuropsychiatric disorders, but the specificity of these deficits remains unclear. The aim of the present study was to elucidate the pattern of EF impairment across psychopathologies in children and adolescents. Associations among components of EF with dimensions of psychopathology, including an overall psychopathology factor, were assessed.Method: Participants (8-21 years) were from the Philadelphia Neurodevelopmental Cohort (N = 9,498). Data from a structured clinical screening interview were reduced to 5 dimensional domains using factor analyses: overall psychopathology, anxious-misery, fear, externalizing, and psychosis. EF components of attentional vigilance, response inhibition, conceptual flexibility, and working memory were assessed. Associations of clinical dimensions with general EF ability and with specific EF components were examined.Results: EF ability showed common and domain-specific associations with clinical symptoms. General EF was directly associated with the general psychopathology, anxious-misery, and psychosis domains but not with the fear or externalizing domains. For the EF subcomponents, differences emerged in the magnitude and direction of the association between components and clinical domains. Poorer EF was typically associated with increased symptoms across clinical domains; however, in some instances, better EF ability was associated with greater symptom burden, particularly in the fear domain.Conclusion: EF has widespread associations with psychopathology in youth. Findings showed some overlap in the type of EF impairment across clinical phenotypes, as indicated by similar patterns of associations between some clinical symptoms and EF. However, findings also showed domain-specific associations with EF that differed across EF components and clinical domains. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Objective: To determine the epidemiology of bleeding in critically ill children.Study Design: We conducted a cohort study of children <18 years old admitted to the pediatric intensive care unit for >24 hours and without clinically relevant bleed (CRB) on admission. CRB was defined as resulting in severe physiologic derangements, occurring at a critical site or requiring major therapeutic interventions. Using a novel bleeding assessment tool that we developed, characteristics of the CRB were abstracted from the medical records independently and in duplicate. From the cohort, we matched each child with CRB to 4 children without CRB based on onset of CRB. Risk factors and complications of CRB were identified from this matched group of children.Results: We analyzed 405 children with a median age of 35 months (IQR 7-130 months). A total of 37 (9.1%) children developed CRB. The median number of days with CRB was 1 day (IQR 1-2 days). Invasive ventilation (OR 61.35; 95% CI 6.27-600.24), stress ulcer prophylaxis (OR 2.70; 95% CI 1.08-6.74), surgical admission (OR 0.29; 95% CI 0.10-0.84), and aspirin (OR 0.04; 95% CI 0.002-0.58) were associated with CRB. CRB was associated with longer time to discharge from the unit (hazard ratio 0.20; 95% CI 0.13-0.33) and the hospital (hazard ratio 0.49; 95% CI 0.33-0.73). Children with CRB were on vasopressor longer and transfused more red blood cells after the CRB than those without CRB.Conclusions: Our findings suggest that bleeding complicates critical illness in children.

- Abstract
Background: We sought to establish a metric for easily estimating bleeding and transfusion risks for cardiac surgery patients after antiplatelet agent use. Methods: Deidentified records of patients who underwent coronary artery bypass grafting (CABG) at our institution (January 2010-June 2011) were searched for patients without identified risk factors for excessive bleeding who underwent documented P2Y
12 testing after clopidogrel administration (n = 276). Clinical outcomes were analyzed according to whether preoperative platelet function was higher (platelet reactivity units [PRUs], ≥237) or lower (PRU, <237) and according to preoperative PRU cutoffs: high (>290, or no clopidogrel), intermediate (200-290), or low (<200). Results: Eighty-five patients (57%) received allogeneic blood products at 24 hours or less postoperatively: 33 (22%) received fresh frozen plasma, and 57 (38%) received platelets. The median 12-hour chest tube output (CTO) was 350 mL (interquartile range, 260-490 mL); CTO was “high” (>437 mL) in 62 (42%) of the clopidogrel-treated patients. Lower-PRU patients were more likely to receive coagulation factors (odds ratio [OR], 2.82; P = .0004) and to have high CTO or coagulation factor transfusion (OR, 2.35; P = .02) than higher-PRU patients. Likewise, intermediate- and low-PRU patients had incrementally greater incidences of high CTO (OR, 1.72; P = .002) and coagulation factor transfusion (OR, 2.08; P < .0001) than high-PRU/no clopidogrel patients. High CTO or coagulation factor transfusion was more frequent in intermediate-PRU (OR, 2.67; P = .02) and low-PRU (OR, 5.08; P = .0002) patients than in high-PRU/no clopidogrel patients. Conclusions: Among clopidogrel-treated CABG patients, preoperative platelet function testing can identify those at increased risk for postoperative bleeding and transfusion.

A method for rapid fabrication of polymer cross-linked silica aerogel through laser induced photogelation and the effect of pre-heating, irradiation conditions, and gelation solvent on the structural and mechanical properties of the resulting aerogel material is presented here. An ethanolic solution of an alkoxysilane (tetraorthosilicate, TEOS), a monomer (hexanedioldiacrylate, HDDA), a visible-light free-radical photoinitiator (Eosin Y) and a tertiary amine (as co-initiator and pH modifier), was prepared. The solution was irradiated with a laser beam, and the energy liberated by the polymerization reactions induced gelation in a matter of seconds. The alcogel was then dried into aerogel using the ethanol-water (or acetone-water) azeotrope mixture as a drying fluid. It was observed that pre-heated solutions gelled instantly and the resulting aerogels showed density, Young's modulus and surface area values comparable to those of aerogels produced through conventional methods. The solutions without pre-heating gelled relatively slowly and yielded composites with Young's modulus values about 3 times and surface areas about 1.5 times smaller than the pre-heated samples. The replacement of ethanol with acetone as a gelation solvent accelerated gelation; however, the composites shrank about 2 times more than samples prepared using ethanol and, consequently, had higher densities and moduli and decreased surface areas. The potential exists for mold-free and rapid fabrication of bulk or thin film aerogel structures using this method to open new avenues for their application in areas such as 3D printing.

Background: COVID-19 pandemic has major ramifications for global health and economy, with growing concerns about economic recession and implications for mental health. Here we investigated the associations between pandemic-related income loss with financial strain and mental health trajectories over a 1-month course, in two independent cohorts.Methods: Two independent studies were conducted in the U.S and in Israel at the beginning of the outbreak (March-April 2020, T1; study I: N = 2904, study II: N = 1267) and at a 1-month follow-up (T2; study I: N = 1318, study II: N = 241). Mixed-effects models were applied to assess associations among COVID-19-related income loss, financial strain, and pandemic-related worries about health, with anxiety and depression, controlling for multiple covariates including pre-COVID-19 income.Results: In both studies, income loss and financial strain were associated with greater depressive symptoms at T1, above and beyond T1 anxiety, worries about health, and pre-COVID-19 income. Worsening of income loss was associated with exacerbation of depression at T2 in both studies. Worsening of subjective financial strain was associated with exacerbation of depression at T2 in one study (US).Conclusions: Income loss and financial strain were uniquely associated with depressive symptoms and their exacerbation over time, above and beyond pandemic-related anxiety. In times when a myriad of stressors are affecting mental health worldwide, our findings reveal specific links between the economic impact of COVID-19 and psychiatric outcomes.

POROUS silica , *SILICA gel , *SORBENTS , *AZEOTROPES , *CALCINATION (Heat treatment) - Abstract
Hierarchically porous silica monoliths are obtained in the two-step Nakanishi process, where formation of a macro–microporous silica gel is followed by widening micropores to mesopores through surface etching. The latter step is carried out through hydrothermal treatment of the gel in alkaline solution and necessitates a lengthy solvent exchange of the aqueous pore fluid before the ripened gel can be dried and calcined into a mechanically stable macro–mesoporous monolith. We show that using an ethanol–water (95.6/4.4, v/v) azeotrope as supercritical fluid for mesopore etching eliminates the solvent exchange, ripening, and drying steps of the classic route and delivers silica monoliths that can withstand fast heating rates for calcination. The proposed shortcut decreases the overall preparation time from ca. one week to ca. one day. Porosity data show that the alkaline conditions for mesopore etching are crucial to obtain crack-free samples with a narrow mesopore size distribution. Physical reconstruction of selected samples by confocal laser scanning microscopy and subsequent morphological analysis confirms that monoliths prepared via the proposed shortcut possess the high homogeneity of silica skeleton and macropore space that is desirable in adsorbents for flow-through applications.

Context: Treatment guidelines recommend the use of combination therapies for smoking cessation, particularly behavioral therapy (BT) as an adjunct to pharmacotherapy. However, these guidelines rely on previous reviews with important limitations. This study's objective was to evaluate the efficacy of combination therapies compared with monotherapies, using the most rigorous data available.Evidence Acquisition: A systematic review and meta-analysis of RCTs of pharmacotherapies, BTs, or both were conducted. The Cochrane Library, Embase, PsycINFO, and PubMed databases were systematically searched from inception to July 2015. Inclusion was restricted to RCTs reporting biochemically validated abstinence at 12 months. Direct and indirect comparisons were made in 2015 between therapies using hierarchical Bayesian models.Evidence Synthesis: The search identified 123 RCTs meeting inclusion criteria (60,774 participants), and data from 115 (57,851 participants) were meta-analyzed. Varenicline with BT increased abstinence more than other combinations of a pharmacotherapy with BT (varenicline versus bupropion: OR=1.56, 95% credible interval [CrI]=1.07, 2.34; varenicline versus nicotine patch: OR=1.65, 95% CrI=1.10, 2.51; varenicline versus short-acting nicotine-replacement therapies: OR=1.68, 95% CrI=1.15, 2.53). Adding BT to any pharmacotherapy compared with pharmacotherapy alone was inconclusive, owing to wide CrIs (OR=1.17, CrI=0.60, 2.12). Nicotine patch with short-acting nicotine-replacement therapy appears safe and increases abstinence versus nicotine-replacement monotherapy (OR=1.63, CrI=1.06, 3.03). Data are limited concerning other pharmacotherapy combinations and their safety and tolerability.Conclusions: Evidence suggests that combination therapy benefits may be less than previously thought. Combined with BT, varenicline increases abstinence more than other pharmacotherapy with BT combinations. [ABSTRACT FROM AUTHOR]- Published

Abstract: Cells use three main ways of generating energy currency to drive metabolism: (i) conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP) by the proton motive force through the rotor-stator ATP synthase; (ii) the synthesis of inorganic phosphate∼phosphate bonds via proton (or sodium) pyrophosphate synthase; or (iii) substrate-level phosphorylation through the direct donation from an active phosphoryl donor. A mechanism to produce a pyrophosphate bond as “energy currency” in prebiotic systems is one of the most important considerations for origin of life research. Baltscheffsky (1996) suggests that inorganic pyrophosphate ( ; PPi) may have preceded ATP/ADP as an energy storage molecule in earliest life, produced by an H+ pyrophosphatase. Here we test the hypothesis that PPi could be synthesized in inorganic precipitates simulating hydrothermal chimney structures transected by thermal and/or ionic gradients. Appreciable yields of PPi were obtained via substrate phosphorylation by acetyl phosphate within the iron sulfide/silicate precipitates at temperatures expected for an alkaline hydrothermal system.

GENDER , *PSYCHOPATHY , *AGGRESSION (Psychology) , *GENDER differences (Psychology) - Abstract
Previous research has established relationships between the triarchic model of psychopathy, defined by the TriPM, and aggression. However, recent research has suggested that the TriPM may be better conceptualised as having seven factors (the septarchic model). In a community sample (N = 404), we analysed measures of aggression and rule-breaking against the TriPM at the three-factor and seven-factor levels, differentiating by gender. Consistent with the septarchic conceptualisation, some factors under each of the three TriPM domains showed different relationships to aggression. For instance, the septarchic subscale of 'Enjoy Hurting' associated with all measures of aggression while 'Callous' had no or weak relationships. The 'Antisocial' scale was associated with proactive aggression (but not reactive aggression) while the 'Impulsive' scale showed the opposite pattern. Few gender differences emerged in the relationships between psychopathy and gender. Overall, the septarchic model revealed relationships between psychopathy and aggression that are not apparent from the triarchic model and thus, may allow a more refined picture of aggression and psychopathy. • Unique relationships emerged between 7-factor psychopathy subscales and aggression. • Enjoy hurting associated with all types of aggression • No or weak associations were found between callous and aggression. • There were few gender differences related to psychopathy.

Abstract: This study investigates early executive attention in infancy by studying the relations between infant sequential looking and other behaviors predictive of later self-regulation. One early marker of executive attention development is anticipatory looking, the act of looking to the location of a target prior to its appearance in that location, a process that involves endogenous control of visual orienting. Previous studies have shown that anticipatory looking is positively related to executive attention as assessed by the ability to resolve spatial conflict in 3–4-year-old children. In the current study, anticipatory looking was positively related to cautious behavioral approach in response to non-threatening novel objects in 6- and 7-month-old infants. This finding and previous findings showing the presence of error detection in infancy are consistent with the hypothesis that there is some degree of executive attention in the first year of life. Anticipatory looking was also related to the frequency of distress, to looking away from disturbing stimuli, and to some self-regulatory behaviors. These results may indicate either early attentional regulation of emotion or close relations between early developing fear and later self-regulation. Overall, the results suggest the presence of rudimentary systems of executive attention in infants and support further studies using anticipatory looking as a measure of individual differences in attention in infancy.

Objective: Behavioral inhibition (BI) during early childhood predicts risk for anxiety disorders and altered cognitive control in adolescence. Although BI has been linked to variation in brain function through adulthood, few studies have examined relations between early childhood BI and adult brain structure.Method: The relation between early childhood BI and cortical thickness in adulthood was examined in a cohort of individuals followed since early childhood (N = 53, mean age 20.5 years). Analyses tested whether anxiety and/or cognitive control during adolescence moderated relations between BI and cortical thickness. Cognitive control was measured with the Eriksen Flanker Task. Initial analyses examined cortical thickness in regions of interest previously implicated in BI, anxiety disorders, and cognitive control: dorsal anterior cingulate (dACC), anterior insula (aI), and subgenual anterior cingulate (sgACC); and volumes of the amygdala and hippocampus. Exploratory analyses examined relations across the prefrontal cortex.Results: BI during early childhood related to thinner dACC in adulthood. Neither anxiety nor cognitive control moderated this relation. A stronger congruency effect on the Eriksen Flanker Task during adolescence independently related to thinner dACC in adulthood. Higher anxiety during adolescence related to thicker cortex in the right ventrolateral prefrontal cortex (VLPFC) in adulthood among those with low BI as children.Conclusion: Temperament in early childhood and the interaction between temperament and later anxiety relate to adult brain structure. These results are consistent with prior work associating BI and anxiety with functional brain variability in the dACC and VLPFC. [ABSTRACT FROM AUTHOR]- Published
