Psychosocial Adjustment of Children With Migraine and Tension‐Type Headache – A Nationwide Study
Authors: Arruda Marco A. , Arruda Renato , Guidetti Vincenzo , Bigal Marcelo E. 
Published: February 2015

ObjectiveTo describe patterns of psychosocial adjustment and psychological attributes in preadolescent children as a function of headache status in univariate and adjusted analyses.MethodsTarget sample of children (n = 8599) was representative of Brazil by demographics. Parents were interviewed using validated headache questionnaires and the “Strengths and Difficulties Questionnaire,” which measures behavior in 5 domains. One‐year prevalence estimates of headaches were derived by demographics. Relative risk of abnormal Strengths and Difficulties Questionnaire scores were separately modeled in children with episodic migraine and episodic tension‐type headache using logistic regression.ResultsSample consisted of 5671 children (65.9% of the target sample), from 5 to 12 years old (49.3% girls). Prevalence estimates in children were 20.6% for “no headache,” 9% for episodic migraine, and 12.8% for episodic tension‐type headache. Abnormal scores in psychosocial adjustment were significantly more likely in children with episodic migraine, relative to children without headaches and children with episodic tension‐type headache, and was significantly influenced by frequency of headache attacks, nausea, school performance, prenatal exposure to tobacco, as well as by phonophobia and photophobia.ConclusionsChildren with migraine are at an increased risk of having impairment in psychosocial adjustment, and the factors associated with this impairment have been mapped. Future studies should address the directionality of the association and putative mechanisms to explain it.

AbstractAimThis study examined Latin American evaluation needs regarding the development of a collaborative mental health care (CMHC) evaluation framework as seen by local key health‐care leaders and professionals. Potential implementation challenges and opportunities were also identified.MethodsThis multisite research study used an embedded mixed methods approach in three public health networks in Mexico, Nicaragua and Chile. Local stakeholders participated: decision‐makers in key informant interviews, front‐line clinicians in focus groups and other stakeholders through a survey. The analysis was conducted within site and then across sites.ResultsA total of 22 semi‐structured interviews, three focus groups and 27 questionnaires (52% response rate) were conducted. Participants recognized a strong need to evaluate different areas of CMHC in Latin America, including access, types and quality of services, human resources and outcomes related to mental disorders, including addiction. A priority was to evaluate collaboration within the health system, including the referral system. Issues of feasibility, including the weaknesses of information systems, were also identified.ConclusionLocal stakeholders strongly supported the development of a comprehensive evaluation framework for CMHC in Latin America and cited several dimensions and contextual factors critical for inclusion. Implementation must allow flexibility and adaptation to the local context.
Dawkins is Dead: Long Live Evolution!
Authors: Cunningham Conor 
Published: February 2015

Abstract
What the late Stephen J Gould baptized ultra-Darwinism is
anti-evolutionary. In so being, it leads to the undermining of science,
rationality, and, lastly, to ethical nihilism, wherein any notion of
humanism is impossible, and this for one simple reason – there is now no
such thing as a human. In addition, we argue that ultra-Darwinism is a
progeny of crass philosophical dualism, and this leads it to despise matter
and the material world, even though, paradoxically, it espouses materialism.
We conclude that the theory of evolution invalidates
ultra-Darwinism.

Published: February 2015

The inception of phosphors provoked the need of highly efficient lighting sources for the conceivable next generation applications. In this regards, a striking characteristic material namely the mesoporous silica (MPS) and their series that are quite distinct to each other in their physical properties have been synthesized by adopting a cooperative self‐assemble strategy. Utilizing it, the development of high‐performance Sr1−xCa1−yEux+ySiO4 phosphor was traversed using a simple wet‐solid phase process. Systematic investigations on morphological, structural, and few other physical properties were carried out. The derived results are intriguing with a crystal clear alteration in the phosphor morphology when MPS has been used as a silicate source. Subsequent luminescence studies displayed its efficient yellow‐emitting property covering the red spectral components, along with good thermal luminescence stability. Perhaps, the designed prototype LEDs yielded a color correlation temperature (CCT) < 5000 K and color rendering index (CRI) > 80. Therefore, it directs the way for the fabrication of potential warm white LEDs with a long‐lived emission efficacy and high thermal luminescence stability.

Published: February 2015

The ceramics with the composition of SrxBi7−xFe1.5Co1.5Ti3O21−δ (0 ≤ x ≤ 1, SBFCT) were prepared by a citrate–nitrate combustion method, and the phase evolution with an increasing Sr content was investigated. Pure Aurivillius phase SBFCT with a layer number of n = 6 was obtained when x ≤ 0.25, and then the structure collapsed to 5 layers for x = 0.50, then alternating 4 and 5 layers for x = 0.75, and finally 4 layers for x = 1.00. Meanwhile, secondary phase Sr1−mBimFe1−iCoiO3−γ appeared when x > 0.25, which is antiferromagnetic (AFM) and with low resistivity. Enhanced ferromagnetic and ferroelectric properties were observed from single phase SBFCTs at the room temperature, and the ferromagnetic transition temperature (Tc) increases with the Sr doping level x in the single phase range. The remnant magnetization (2Mr) is 2.27 emu/g and the remnant polarization (2Pr) is 2.89 μC/cm2 at an applied electric field of 100 kV/cm for the x = 0.25 sample.
Understanding the reasons why Chinese older people do not wish to tell their life stories
Authors: Chan Engle A. , Lai Claudia K.Y. 
Published: February 2015

AbstractAimTo explore the reasons why older Chinese people decline to tell their life stories.BackgroundPromoting the telling of life stories by older people, as part of healthy ageing, may develop their sense of unity and meaning in life. However, not all older adults seem to review their past and tell others about it. Understanding is lacking about how ‘healthy’ older adults experience the meanings of not telling.DesignA descriptive phenomenology with Giorgi's analysis.MethodsData were collected from June 2010–August 2011 through unstructured individual interviews. A potential sample of 36 older people were identified through convenience sampling from 17 daycare and senior centres, of whom 19 participated in this study.ResultsOur findings suggest that the reasons why these older people declined to tell their life stories relate to an understanding of the self and to the perception that the older people had of their audience's response and their family's support. Older people seemed to be naturally inclined to reminiscence, but their accumulated personal and interpersonal experiences might have caused them to feel disinclined to talk about what they no longer considered to be important.ConclusionAn understanding about the tension existing in cultural/generational narratives of the older people may help health professionals to provide them with a supportive environment for their continuous construction of social identities. This may contribute to their better social health. Equally important is to provide an opportunity for them to share their stories and engage in family and cross‐generational dialogues.

Published: February 2015

BackgroundThis study examined whether relocating from a high‐poverty neighborhood to a lower poverty neighborhood as part of a federal housing relocation program (HOPE VI; Housing Opportunities for People Everywhere) had effects on adolescent mental and behavioral health compared to adolescents consistently living in lower poverty neighborhoods.MethodsSociodemographic, risk behavior, and neighborhood data were collected from 592 low‐income, primarily African‐American adolescents and their primary caregivers. Structured psychiatric interviews were conducted with adolescents. Prerelocation neighborhood, demographic, and risk behavior data were also included. Hierarchical Linear Modeling (HLM) was used to test associations between neighborhood variables and risk outcomes. HLM was used to test whether the effect of neighborhood relocation and neighborhood characteristics might explain differences in sexual risk taking, substance use, and mental health outcomes.ResultsAdolescents who relocated of HOPE VI neighborhoods (n = 158) fared worse than control group participants (n = 429) on most self‐reported mental health outcomes. The addition of subjective neighborhood measures generally did not substantively change these results.ConclusionsOur findings suggest that moving from a high‐poverty neighborhood to a somewhat lower poverty neighborhood is not associated with better mental health and risk behavior outcomes in adolescents. The continued effects of having grown up in a high‐poverty neighborhood, the small improvements in their new neighborhoods, the comparatively short length of time they lived in their new neighborhood, and/or the stress of moving appears to worsen most of the mental health outcomes of HOPE VI compared to control group participants who consistently lived in the lower poverty neighborhoods.
TCInvestigator: automated calculation of mineral mode and composition contours for thermocalc pseudosections

Published: February 2015

AbstractForward thermodynamic modelling is a commonly used tool for examining the thermobarometric history of a rock. Such models are being applied to a widening range of rock types using increasingly complex model systems. A useful aspect of phase equilibria modelling using pseudosections is the ability to calculate the modal abundance and compositions of phases, in addition to overall phase relations. However, calculating and plotting such data with thermocalc, a popular modelling program, is time consuming. In this article, we provide the methods and a description of a Matlab® computer program, TCInvestigator, which uses thermocalc 3.40 to automatically contour pre‐calculated pressure–temperature pseudosections with modal abundance and mineral composition parameters. The ability to calculate, plot and visualize these parameters automatically and rapidly, allows for a more in‐depth investigation into the metamorphic evolution of a rock. Data can be contoured for all minerals that are present in all fields on the pseudosection, rather than a selection of fields or phases that are a priori considered relevant. Examples of contoured pseudosections for pelitic and greywacke bulk compositions are presented, along with accompanying data sets, to illustrate the applications of this program.

Published: February 2015

AbstractBackgroundThe studies on ophthalmic diseases and disorders in a population of rhesus macaques, in particular with free‐ranging macaques, are limited mainly by the difficulty in capturing animals and obtaining samples.MethodsFrom October 2011 to 2013, prevalence of various ophthalmic affections was recorded and analyzed on the basis of sex, age‐group, and disease condition both in urban and peri‐urban free‐ranging rhesus macaques (Macaca mulatta) from various locations in Shivalik hill areas of Himachal Pradesh in northern India, as a part of clinical health examination.Results and conclusionOphthalmic diseases were more prevalent in macaques captured from urban settings than those from peri‐urban, and difference between two groups was statistically significant (P < 0.01). Further classification of ophthalmic diseases revealed that traumatic injuries, corneal opacity, and cataract were significantly higher in urban than those in peri‐urban macaque (P < 0.01). Similarly, the ophthalmic disorders among different age‐groups were also found statistically significant (P < 0.01). The effect of sex on ophthalmic disorders was not found significant. Overviewing these results, disturbances in environment, close proximity to humans, and increasing age may lead to ophthalmic occurrences in these free‐range macaques.
Is a VC Partnership Greater Than the Sum of Its Partners?
Authors: EWENS MICHAEL , RHODES‐KROPF MATTHEW 
Published: February 2015

ABSTRACTThis paper investigates whether individual venture capitalists have repeatable investment skill and the extent to which their skill is impacted by the venture capital (VC) firm where they work. We examine a unique data set that tracks the performance of individual venture capitalists' investments over time and as they move between firms. We find evidence of skill and exit style differences even among venture partners investing at the same VC firm at the same time. Furthermore, our estimates suggest the partners' human capital is two to five times more important than the VC firm's organizational capital in explaining performance.

AbstractAimSeveral predictive tools of non‐sentinel lymph nodes neoplastic involvement when a positive sentinel lymph node is found have been described. However, molecular factors have been rarely evaluated to build these tools. The aim of this study was to establish which factors predicted non‐sentinel lymph nodes infiltration in our setting, including some molecular factors.Material and MethodsWe carried out a retrospective review of 161 patients with breast cancer and a positive sentinel lymph node who had undergone axillary lymph node dissection, none of whom had received neoadjuvant treatment. Features evaluated as predictive factors for non‐sentinel node positivity were: menopausal status, tumor size, histological subtype, histological grade, lymphovascular invasion, extracapsular invasion, Ki67 index, hormonal receptors, CerbB2 and p53 expression, size of sentinel lymph node metastases and number of sentinel lymph nodes affected.ResultsTumor size (P = 0.001), size of sentinel lymph node metastases (P = 0.001), lobular invasive carcinoma (P = 0.05) and lymphovascular invasion (P = 0.006) were significantly associated with non‐sentinel lymph node positivity. Tumor p53 positive expression was strongly associated with non‐sentinel lymph node negativity (P = 0.000). In multivariate analysis, all these factors but tumor size maintained their significance. The discrimination power of the model calculated by the area under the receiver–operator curve was 0.811 (95% confidence interval, 0.741–0.880).Conclusionp53 expression in breast cancer was highly predictive of non‐sentinel lymph node negativity in our study. New studies should evaluate if it would be useful to add p53 expression to other existing predictive tools.
Simplified Technique for Incorporating a Metal Mesh into Record Bases for Mandibular Implant Overdentures
Authors: Godoy Antonio , Siegel Sharon C. 
Published: February 2015

AbstractMandibular implant‐retained overdentures have become the standard of care for patients with mandibular complete edentulism. As part of the treatment, the mandibular implant‐retained overdenture may require a metal mesh framework to be incorporated to strengthen the denture and avoid fracture of the prosthesis. Integrating the metal mesh framework as part of the acrylic record base and wax occlusion rim before the jaw relation procedure will avoid the distortion of the record base and will minimize the chances of processing errors. A simplified method to incorporate the mesh into the record base and occlusion rim is presented in this technique article.

Published: February 2015

Accessible summaryThis paper adds a phenomenological hermeneutic perspective on meanings of caring for adult people who self‐harm as disclosed in narratives of dialectical behaviour therapy (DBT)‐trained professionals.This paper shows that providing DBT care for people who self‐harm means embarking an unpredictable journey, sometimes lonely, but also often together with the person who self‐harm and with the DBT team.This paper emphasizes professionals' benefits of the tools and structure offered by DBT; however, the text points to the importance of the genuine meeting, including confirmation, as a prerequisite to recovery.This paper suggests that further research might focus on the meanings of genuine meetings and their organizational prerequisites.AbstractIn this paper, we aim to explore meanings of caring for adult people who self‐harm as described in the narratives of professionals trained in dialectical behaviour therapy (DBT). We conducted narrative interviews with nine professionals working in aDBTteam and used a phenomenological hermeneutical method to analyse their narratives. Our comprehensive understanding cast the caring relationship as an unpredictable journey, in which the professionals were guides or companions who aimed to walk side‐by‐side with the person who self‐harms, prove to be trustworthy, and keep on track. They sometimes saw the journey as lonely and sometimes as a joint endeavour. Our analysis was informed byMartinBuber's writings on the ‘genuine meeting’ and confirmation. The professionals emphasized the importance of the tools and structure offered byDBT; however, the text points to the importance of the genuine meeting, including confirmation, as a prerequisite to recovery. Mental health nurses need opportunities for continuous training and counselling.
Dynamic Spectral Analysis of Jagged Mechanical Signatures of a Brittle Puffed Snack
Authors: Sanahuja Solange , Briesen Heiko 
Published: February 2015

AbstractThe instrumental evaluation of crispiness and crunchiness of dry and wet cellular foods is challenging. Available texture analysis methods do not always reliably predict sensory analysis results. Temporal sensory integration is suspected to be a key factor in the perception of crispiness and crunchiness. Thus, short‐time Fourier transform, continuous wavelet transform and Hilbert–Huang transform are proposed and applied as dynamic alternatives for analyzing multifracture events. The resulting time–frequency–magnitude spectra graphically show the degree of similarity between the samples. These representations contribute to an understanding of the dynamics of airy foods' jagged mechanical signatures, as demonstrated on corn starch extrudates. In most cases, they finally permit the recognition or discrimination of similarities and differences in the degree of brittleness, corresponding to a specific production process and water content. The analytical techniques should help to determine relevant and objective characteristics that correlate with sensory studies.Practical ApplicationsShort‐time Fourier transform, continuous wavelet transform and Hilbert–Huang transform help to understand the physical processes and the temporal evolution of the breakage behavior of foods. They are powerful tools for analyzing jagged mechanical and acoustic food signatures. Each method offers a different perspective, thereby enabling the exploration of unforeseen characteristics that could lead to better predictions of sensory‐felt crispiness and crunchiness. A food's dynamic fingerprint helps in recognition of similar products that belong to the same family, despite natural individuality, and aids the discrimination between different products. After relating classified food samples to their structure and consumer preferences, food structure design and quality control can be improved. The methods can be applied to multidisciplinary food texture studies that examine air‐conducted crushing sounds, bone‐conducted vibrations, dampening effects of muscles and fatty tissues, or chewing muscle and neural activities. This manuscript intends to make modern techniques of signal analysis more accessible to food scientists.
A high‐throughput screen for ligand binding reveals the specificities of three amino acid chemoreceptors from Pseudomonas syringae pv. actinidiae

Published: February 2015

SummaryChemoreceptors play a central role in chemotaxis, allowing bacteria to detect chemical gradients and bias their swimming behavior in order to navigate toward favorable environments. The genome of the kiwifruit pathogen, Pseudomonas syringae pv. actinidiae (Psa) strain NZ‐V13 encodes 43 predicted chemoreceptors, none of which has been characterized. We developed a high‐throughput fluorescence‐based thermal shift assay for identifying the signal molecules that are recognized by a given chemoreceptor ligand binding domain (LBD). Using this assay, we characterized the ligand binding profiles of three Psa homologs of the P. aeruginosa PAO1 amino acid chemoreceptors PctA, PctB and PctC. Each recombinant LBD was screened against 95 potential ligands. The three Psa homologs, named pscA, pscB and pscC (Psa chemoreceptors A, B and C) bound 3, 10 and 3 amino acids respectively. In each case, their binding profiles were distinct from their P. aeruginosa PAO1 homologs. Notably, Psa PscA‐LBD only bound the acidic amino acids l‐aspartate, d‐aspartate and l‐glutamate, whereas P. aeruginosa PctA‐LBD binds all of the l‐proteinogenic amino acids except for l‐aspartate and l‐glutamate. A combination of homology modeling, site‐directed mutagenesis and functional screening identified a single amino acid residue in the Psa PscA‐LBD (Ala146) that is critically important for determining its narrow specificity.
