Children's Oncology Group's 2013 blueprint for research: Non‐Hodgkin lymphoma

Non‐Hodgkin lymphomas account for approximately 7% of cancers diagnosed in patients less than 20 years of age, with approximately 800 cases diagnosed annually at COG institutions. With current therapies, cure rates range from 70% to over 90%, even for children with disseminated disease. However, two major challenges need to be overcome: (i) to optimize upfront treatment to prevent relapse since prognosis for patients with relapsed disease remains poor and (ii) minimize long‐term side effects in survivors. Hence, the future initiatives for the treatment of pediatric NHL are to utilize novel targeted therapies to not only improve outcomes but to decrease bystander organ toxicities and late effects.

Structural cut elimination

Presents new proofs of cut elimination for intuitionistic, classical and linear sequent calculi. In all cases, the proofs proceed by three nested structural inductions, avoiding the explicit use of multi-sets and termination measures on sequent derivations. This makes them amenable to elegant and concise implementations in Elf, a constraint logic programming language based on the LF logical framework.

On length spectrum metrics and weak metrics on Teichmueller spaces of surfaces with boundary

We define and study metrics and weak metrics on the Teichmueller space of a surface of topologically finite type with boundary. These metrics and weak metrics are associated to the hyperbolic length spectrum of simple closed curves and of properly embedded arcs in the surface. We give a comparison between the defined metrics on regions of Teichmueller space which we call $\varepsilon_0$-relative $\epsilon$-thick parts} for $\epsilon >0$ and $\varepsilon_0\geq \epsilon>0$.
Poverty and Brain Development During Childhood: An Approach from Cognitive Psychology and Neuroscience. Human Brain Development Series.

Poverty remains an urgent crisis worldwide. In the United States, 28.6 million children live in low-income families and 12.7 million children live in poor families. In nations belonging to the Organization for Economic Co-operation and Development (OECD), 47 million children live below national poverty lines. These figures pertain to industrialized countries; rates of child poverty in some developing nations exceed 60 per cent. "Poverty and Brain Development During Childhood" examines how a range of early social and material deprivations affect structural and functional brain organization and cognitive and socioemotional development postnatally and throughout childhood. Do conceptual and operational definitions of poverty capture the true nature and complexity of the multidimensional problem and properly guide research? How does poverty affect physical and mental health? What do contemporary neuroimaging and behavioral studies reveal? Studying these and other equally compelling questions, the authors apply a suite of neuroscientific and cognitive frameworks to examine the cognitive performance of children living in poverty in different countries. Looking to the future and to the development of effective policy, the authors analyze the potential contributions of the neuroscientific disciplines to the design of early interventions aimed at optimizing the cognitive performance of socioeconomically disadvantaged children. This book is suitable for researchers, policymakers, neuroscientists, developmental psychologists, and students.
Flavonoid-Rich Dark Chocolate Improves Endothelial Function and Increases Plasma Epicatechin Concentrations in Healthy Adults

Background: Dark chocolate derived from the plant (Theobroma cacao) is a rich source of flavonoids. Cardioprotective effects including antioxidant properties, inhibition of platelet activity, and activation of endothelial nitric oxide synthase have been ascribed to the cocoa flavonoids. Objective: To investigate the effects of flavonoid-rich dark chocolate on endothelial function, measures of oxidative stress, blood lipids, and blood pressure in healthy adult subjects. Design: The study was a randomized, double-blind, placebo-controlled design conducted over a 2 week period in 21 healthy adult subjects. Subjects were randomly assigned to daily intake of high-flavonoid (213 mg procyanidins, 46 mg epicatechin) or low-flavonoid dark chocolate bars (46 g, 1.6 oz). Results: High-flavonoid chocolate consumption improved endothelium-dependent flow-mediated dilation (FMD) of the brachial artery (mean change = 1.3 ± 0.7%) as compared to low-flavonoid chocolate consumption (mean change = −0.96 ± 0.5%) (p = 0.024). No significant differences were noted in the resistance to LDL oxidation, total antioxidant capacity, 8-isoprostanes, blood pressure, lipid parameters, body weight or body mass index (BMI) between the two groups. Plasma epicatechin concentrations were markedly increased at 2 weeks in the high-flavonoid group (204.4 ± 18.5 nmol/L, p ≤ 0.001) but not in the low-flavonoid group (17.5 ± 9 nmol/L, p = 0.99). Conclusion: Flavonoid-rich dark chocolate improves endothelial function and is associated with an increase in plasma epicatechin concentrations in healthy adults. No changes in oxidative stress measures, lipid profiles, blood pressure, body weight or BMI were seen.
Safety of cold-adapted live attenuated influenza vaccine in a large cohort of children and adolescents

Objective. To determine the safety of cold-adapted trivalent intranasal influenza virus vaccine (CAIV) in children and adolescents. Study design. A randomized, double blind, placebo-controlled safety trial in healthy children age 12 months to 17 years given CAIV (FluMist; MedImmune Vaccines, Inc.) or placebo (randomization, 2:1). Children <9 years of age received a second dose of CAIV or placebo 28 to 42 days after the first dose. Enrolled children were then followed for 42 days after each vaccination for all medically attended events. Prespecified outcomes included 4 prespecified diagnostic groups and 170 observed individual diagnostic categories. The relative risk and the 2-sided 90% confidence interval were calculated for each diagnostic group and individual category by clinical setting, dose and age. More than 1500 relative risk analyses were performed. Results. A total of 9689 evaluable children were enrolled in the study. Of the 4 prespecified diagnostic categories (acute respiratory tract events, systemic bacterial infection, acute gastrointestinal tract events and rare events potentially associated with wild-type influenza), none was associated with vaccine. Of the biologically plausible individual diagnostic categories, 3, acute gastrointestinal events, acute respiratory events and abdominal pain, had different analyses that demonstrated increased and decreased relative risks, making their association with the vaccine unlikely. For reactive airway disease a significant increased relative risk was observed in children 18 to 35 months of age with a relative risk of 4.06 (90% confidence interval, 1.29 to 17.86) in this age group. The individual diagnostic categories of upper respiratory infection, musculoskeletal pain, otitis media with effusion and adenitis/adenopathy had at least one analysis that achieved a significant increased risk ratio. All of these events were infrequent. Conclusion. CAIV was generally safe in children and adolescents. The observation of an increased risk of asthma/reactive airway disease in children <36 months of age is of potential concern. Further studies are planned to evaluate the risk of asthma/reactive airway disease after vaccine.
Cronobacter gen. nov., a new genus to accommodate the biogroups of Enterobacter sakazakii, and proposal of Cronobacter sakazakii gen. nov., comb. nov., Cronobacter malonaticus sp. nov., Cronobacter turicensis sp. nov., Cronobacter muytjensii sp. nov., Cronobacter dublinensis sp. nov., Cronobacter ge

[Enterobacter] sakazakii is an opportunistic pathogen that can cause infections in neonates. This study further clarifies the taxonomy of isolates described as [E. ] sakazakii and completes the formal description of the proposed reclassification of these organisms as novel species and subspecies within a proposed novel genus, Cronobacter gen. nov. [E. ] sakazakii was first defined in 1980, however recent polyphasic taxonomic analysis has determined that this group of organisms consists of several genomospecies. In this study, the phenotypic descriptions of the proposed novel species are expanded using Biotype 100 and Biolog Phenotype MicroArray data. Further DNA-DNA hybridization experiments showed that malonate-positive strains within the [E. ] sakazakii genomospecies represent a distinct species, not a subspecies. DNA-DNA hybridizations also determined that phenotypically different strains within the proposed species, Cronobacter dublinensis sp. nov., belong to the same species and can be considered as novel subspecies. Based on these analyses, the following alternative classifications are proposed: Cronobacter sakazakii gen. nov., comb. nov. [type strain ATCC 29544(T) (=NCTC 11467(T))]; Cronobacter malonaticus sp. nov. [type strain CDC 1058-77(T) (=LMG 23826(T)=DSM 18702(T))]; Cronobacter turicensis sp. nov. [type strain z3032(T) (=LMG 23827(T)=DSM 18703(T))]; Cronobacter muytjensii sp. nov. [type strain ATCC 51329(T) (=CIP 103581(T))]; Cronobacter dublinensis sp. nov. [type strain DES187(T) (=LMG 23823(T)=DSM 18705(T))]; Cronobacter dublinensis subsp. dublinensis subsp. nov. [type strain DES187(T) (=LMG 23823(T)=DSM 18705(T))]; Cronobacter dublinensis subsp. lausannensis subsp. nov. [type strain E515(T) (=LMG 23824=DSM 18706(T))], and Cronobacter dublinensis subsp. lactaridi subsp. nov. [type strain E464(T) (=LMG 23825(T)=DSM 18707(T))].
A 5-year Review of Darning Technique of Inguinal Hernia Repair

Context: The Darning technique of inguinal hernia repair is a tissue-based technique with documented low recurrence rate in some parts of the world. Though practiced in our setting, little is documented on its outcome. Aims: The aim was to review the outcome of Darning technique of inguinal hernia repair in our setting. Study Design: A descriptive retrospective study. Patients and Methods: Clinical records of all patients who had inguinal hernia repair using the Darning technique between January 2007 and December 2011 in our institution were obtained. Details of sociodemographic data, intraoperative findings and postoperative complications were reviewed. Statistical Analysis Used: simple frequencies, proportions and cross-tabulations. Results: A total of 132 patients whose ages ranged from 15 to 84 years (mean = 49.4 years) with a male: female ratio of 12:1 were studied. Majority of the hernias were right sided (68.9%), mostly indirect (81.8%). The procedures were for emergencies in 17 (12.9%) cases whereas the rest (87.1%) were done electively. Most procedures, 110 (83.3%) were performed under local anesthesia. Surgical site infection was the most common complication occurring in six patients (4.5%), while four patients (3%) had chronic groin pain. At a mean follow-up period of 15 months there were two recurrences (1.5%) both occurring in patients with bilateral hernias (P = 0.001). Conclusions: The Darning technique of inguinal hernia repair is a safe and effective method for inguinal hernia repair in our setting.
Empowerment Cognitions and Empowerment Acts

By distinguishing between empowerment cognitions and empowerment acts, the effect of gender is tested on (a) the impact of empowerment and disempowerment acts on subordinates’ empowerment cognitions, and (b) the direct impact of these acts on subsequent job satisfaction and performance. A total of 135 master of business administration students participated in a three-session simulation of the empowerment process. Findings indicate that although empowerment cognitions are affected by empowerment and disempowerment acts for both men and women, the impact of empowerment acts on job satisfaction and performance varies by gender.
Psychosocial risk in adolescence: Individual differences, problem behaviour and victimisation in a young adolescent cohort

Early findings relating to individual difference, crime and health are presented from a major new longitudinal study of adolescent development in Edinburgh. 4300 boys and girls (aged 12-13) completed self-report questionnaires containing two abbreviated measures of personality (assessing dimensions of social alienation and impulsivity) and one of self-esteem, together with measures of offending, victimisation and experience of adverse health behaviours. Results suggest that, even in early adolescence, substantial numbers of young people have lifetime experience of both problem behaviour and victimisation and that the various measures tended to co-occur to a moderate extent. Subjects reporting the most problems tended to possess a personality configuration characterised by high levels of impulsivity and social alienation, and lower levels of selfesteem. Whilst important gender differences emerged in terms of global personality scores and behavioural measures (males reporting more ? extreme? values for both), the degree of problem co-occurrence and its association with personality is virtually identical across gender. Findings can be interpreted to an extent with reference to recent theories relating low self-control to generalised risk behaviour. The strong association of risk and personality with victimisation however, forces a re-consideration of the mutual (and perhaps gendered) interaction between individual differences and environment as regards adolescent psychosocial risk
CAMA Centre for Applied Macroeconomic Analysis The New Stylized Facts About Income and Subjective Well-Being CAMA Working Paper 03 / 2013 Jan 2013

In recent decades economists have turned their attention to data that asks people how happy or satisfied they are with their lives. Much of the early research concluded that the role of income in determining well-being was limited, and that only income relative to others was related to well-being. In this paper, we review the evidence to assess the importance of absolute and relative income in determining well-being. Our research suggests that absolute income plays a major role in determining well-being and that national comparisons offer little evidence to support theories of relative income. We find that well-being rises with income, whether we compare people in a single country and year, whether we look across countries, or whether we look at economic growth for a given country. Through these comparisons we show that richer people report higher well-being than poorer people; that people in richer countries, on average, experience greater well-being than people in poorer countries; and that economic growth and growth in well-being are clearly related. Moreover, the data show no evidence for a satiation point above which income and well-being are no longer related. This draft: August 2, 2012
Cryptogenic Stroke in Relation to Genetic Variation in Clotting Factors and Other Genetic Polymorphisms Among Young Men and Women

Background and Purpose— The purpose of the present study was to compare the prevalences of genetic polymorphisms in persons with cryptogenic stroke with those among stroke patients with evidence of large-artery occlusive disease or an unequivocal cardioembolic source (noncryptogenic stroke). Methods— We compared the prevalences of genetic polymorphisms thought to be related to thrombi formation in young stroke patients with evidence of large-artery occlusive disease or an unequivocal cardioembolic source (noncryptogenic stroke; controls; n=79) with those in young stroke patients without such sources (cryptogenic stroke; cases; n=67). Common variations in the genes encoding factor V, prothrombin, angiotensin I–converting enzyme, 5,10-methylenetetrahydrofolate reductase, endothelial cell nitric oxide synthase, tissue plasminogen activator, plasminogen activator inhibitor–1, and fibrinogen were evaluated. We also compared the allele prevalence of these genes among all stroke patients with those among a large pool of historical controls assayed for these genes. Results— None of these genetic polymorphisms was statistically significantly related to cryptogenic stroke. With respect to a comparison of all ischemic stroke with historical controls, only the prevalence of tissue plasminogen activator D allele among stroke subjects was statistically significantly higher than that of the historical controls (P =0.0014). Conclusions— These findings generally do not support the hypothesis that genes associated with a prothrombotic state are risk factors among a subgroup of young people with stroke of undetermined cause. Except for the D tissue plasminogen activator allele, the findings also indicated that these genetic factors are unrelated, or only weakly related, to all ischemic stroke.
Winter Fidelity and Apparent Survival of Lesser Snow Goose Populations in the Pacific Flyway

Abstract The Beringia region of the Arctic contains 2 colonies of lesser snow geese (Chen caerulescens caerulescens) breeding on Wrangel Island, Russia, and Banks Island, Canada, and wintering in North America. The Wrangel Island population is composed of 2 subpopulations from a sympatric breeding colony but separate wintering areas, whereas the Banks Island population shares a sympatric wintering area in California, USA, with one of the Wrangel Island subpopulations. The Wrangel Island colony represents the last major snow goose population in Russia and has fluctuated considerably since 1970, whereas the Banks Island population has more than doubled. The reasons for these changes are unclear, but hypotheses include independent population demographics (survival and recruitment) and immigration and emigration among breeding or wintering populations. These demographic and movement patterns have important ecological and management implications for understanding goose population structure, harvest of admixed populations, and gene flow among populations with separate breeding or wintering areas. From 1993 to 1996, we neckbanded molting birds at their breeding colonies and resighted birds on the wintering grounds. We used multistate mark–recapture models to evaluate apparent survival rates, resighting rates, winter fidelity, and potential exchange among these populations. We also compared the utility of face stain in Wrangel Island breeding geese as a predictor of their wintering area. Our results showed similar apparent survival rates between subpopulations of Wrangel Island snow geese and lower apparent survival, but higher emigration, for the Banks Island birds. Males had lower apparent survival than females, most likely due to differences in neckband loss. Transition between wintering areas was low (<3%), with equal movement between northern and southern wintering areas for Wrangel Island birds and little evidence of exchange between the Banks and northern Wrangel Island populations. Face staining was an unreliable indicator of wintering area. Our findings suggest that northern and southern Wrangel Island subpopulations should be considered a metapopulation in better understanding and managing Pacific Flyway lesser snow geese. Yet the absence of a strong population connection between Banks Island and Wrangel Island geese suggests that these breeding colonies can be managed as separate but overlapping populations. Additionally, winter population fidelity may be more important in lesser snow geese than in other species, and both breeding and wintering areas are important components of population management for sympatric wintering populations.

Explaining Spatial Variation in the Recording Effort of Citizen Science Data across Multiple Taxa

The collation of citizen science data in open-access biodiversity databases makes temporally and spatially extensive species’ observation data available to a wide range of users. Such data are an invaluable resource but contain inherent limitations, such as sampling bias in favour of recorder distribution, lack of survey effort assessment, and lack of coverage of the distribution of all organisms. Any technical assessment, monitoring program or scientific research applying citizen science data should therefore include an evaluation of the uncertainty of its results. We use ‘ignorance’ scores, i.e. spatially explicit indices of sampling bias across a study region, to further understand spatial patterns of observation behaviour for 13 reference taxonomic groups. The data is based on voluntary observations made in Sweden between 2000 and 2014. We compared the effect of six geographical variables (elevation, steepness, population density, log population density, road density and footpath density) on the ignorance scores of each group. We found substantial variation among taxonomic groups in the relative importance of different geographic variables for explaining ignorance scores. In general, road access and logged population density were consistently important variables explaining bias in sampling effort, indicating that access at a landscape-scale facilitates voluntary reporting by citizen scientists. Also, small increases in population density can produce a substantial reduction in ignorance score. However the between-taxa variation in the importance of geographic variables for explaining ignorance scores demonstrated that different taxa suffer from different spatial biases. We suggest that conservationists and researchers should use ignorance scores to acknowledge uncertainty in their analyses and conclusions, because they may simultaneously include many correlated variables that are difficult to disentangle.
