Fat graft migration causing recurrent cervical cord compression.

AIM Fat graft migration following spinal cord surgery is an uncommon problem. Only few cases of fat graft migration causing cauda equine syndrome, recurrent sciatica, and root compression following lumbar spine surgery have been reported. We report a case of fat graft migration causing symptomatic cervical cord compression. MATERIAL AND METHODS A 45-years-old male with cervical spondylosis underwent anterior C4-5 discectomy and excision of hypertrophied ligament. A dural tear that occurred during the procedure was repaired with fat graft harvested from thigh. Significant improvement in stiffness was noted postoperatively. After 15 days, the patient presented again with worsening lower limbs stiffness. Magnetic resonance imaging of spine was done which revealed displacement of the fat graft causing cervical cord compression. RESULTS Re-exploration was done and the migrated fat graft was removed. Post operatively patient noticed significant improvement in stiffness in both lower limbs. CONCLUSION Autologous fat graft is one of the best materials used in sealing the dural cerebrospinal fluid leak during spinal surgery. However sometimes it may migrate and cause compression of cord and roots with relative symptoms. This complication should be kept in mind as removal of migrated fat graft will relieve these symptoms.
Early contrast-enhanced MRI predicts late functional recovery after reperfused myocardial infarction.

BACKGROUND We have observed 3 abnormal patterns on contrast-enhanced MRI early after reperfused myocardial infarction (MI): (1) absence of normal first-pass signal enhancement (HYPO), (2) normal first pass signal followed by hyperenhanced signal on delayed images (HYPER), or (3) both absence of normal first-pass enhancement and delayed hyperenhancement (COMB). This study examines the association between these patterns in the first week after MI and late recovery of myocardial contractile function by use of magnetic resonance myocardial tissue tagging. METHODS AND RESULTS Seventeen patients (14 men) with a mean age of 53+/-12 years were studied after a reperfused first MI. Contrast-enhanced images were acquired immediately after bolus administration of gadolinium and 7+/-2 minutes later. Tagged images were acquired at weeks 1 and 7. Circumferential segment shortening (%S) was measured in regions displaying HYPER, COMB, or HYPO contrast patterns and in remote regions (REMOTE) at weeks 1 and 7. At week 1, %S was depressed in HYPER, COMB, and HYPO (9+/-8%, 7+/-6%, and 5+/-4%, respectively) and were less than REMOTE (18+/-6%, P<0.003). However, in HYPER, %S improved at week 7 from 9+/-8% to 18+/-5% (P<0.001 versus week 1). In contrast, HYPO did not improve significantly (5+/-4% to 6+/-3%, P=NS) and COMB tended to improve 7+/-6% to 11+/-6% (P=0.06). CONCLUSIONS HYPER has partially reversible dysfunction and represents predominantly viable myocardium. COMB shows borderline improvement and likely contains an admixture of viable and necrotic myocardium. HYPO shows little functional improvement at 7 weeks, presumably because of irreversible myocardial damage.
INTERPRETAÇÃO DAS EXIGÊNCIAS DE PRÊMIO POR ALUNOS DE ECONOMIA: UM EXPERIMENTO DE FINANÇAS COMPORTAMENTAIS NA UFPB

Resumo RESUMO O trabalho teve como objetivo analisar, por meio de uma pesquisa descritiva e quantitativa, as exigencias de premio por parte dos alunos do curso de Economia da UFPB. A populacao foi classificada em quatro grupos de acordo com o suposto nivel de conhecimento sobre Financas e Mercado Financeiro, e a amostra, por conveniencia, teve tamanho igual a 20 alunos em cada grupo. Os principais resultados foram os indicios de que, em media, os alunos que, teoricamente, detem menos informacoes ou conhecimento sobre o mercado financeiro, apresentam um comportamento menos aversivo ao risco e de que os grupos interpretam distintamente as diferentes medidas de riscos. Alem disso, constatou-se que as grandes diferencas quanto as exigencias de premios entre os alunos podem ser justificadas pelas diferentes interpretacoes sobre os riscos e que, quanto maior o nivel de conhecimento, menor a dispersao nessas exigencias. Palavras-chave : Financas Comportamentais; Medidas de Riscos; Exigencias de Premio. ABSTRACT The work had as objective to analyze, through a descriptive and quantitative research, the prize expectation by the students of Economics at UFPB. The research population was classified into four major groups, concerning to the knowledge of Finance and Financial Market and each group sample counted of 20 students. The main results pointed out that in average the students who have less knowledge about the financial market are those who also have lower risk behavior and that the groups have different perception of risk measurement. Also, it can be pointed out that the different perception of the risk makes the difference of prize exigencies by the pupils and that the dispersion of the exigencies is smaller as the knowledge of the risk is stronger. Keywords : Behavioral Finance; Risk Measurements; Prize Expectation.
Modulation of Signal Strength Switches Notch from an Inducer of T Cells to an Inducer of ILC2

Innate lymphoid cells (ILCs) are emerging key players of the immune system with close lineage relationship to T cells. ILC2 play an important role in protective immunity against multicellular parasites, but are also involved in the pathogenesis of type 2 immune diseases. Here, we have studied the developmental requirements for human ILC2. We report that ILC2 are present in the thymus of young human donors, possibly reflecting local differentiation. Furthermore, we show that uncommitted lineage−CD34+CD1a−human thymic progenitors have the capacity to develop into ILC2 in vitro under the influence of Notch signaling, either by stimulation with the Notch ligand Delta like 1 (Dll1) or by expression of the active intracellular domain of NOTCH1 (NICD1). The capacity of NICD1 to mobilize the ILC2 differentiation program was sufficiently potent to override commitment to the T cell lineage in CD34+CD1a+ progenitors and force them into the ILC2 lineage. As Notch is an important factor also for T cell development, these results raise the question how one and the same signaling pathway can elicit such distinct developmental outcomes from the same precursors. We provide evidence that Notch signal strength is a critical determinant in this decision: by tuning signal amplitude, Notch can be converted from a T cell inducer (low signal strength) to an ILC2 inducer (high signal strength). Thus, this study enhances our understanding of human ILC2 development and identifies a mechanism determining specificity of Notch signal output during T cell and ILC2 differentiation.
Intermittent Preventive Treatment with Sulfadoxine–Pyrimethamine: More than Just an Antimalarial?

Malaria in pregnancy is associated with increased risk for both maternal and neonatal adverse outcomes, notably low birthweight and neonatal mortality. 1 Since 2004, following studies that showed that intermittent preventive treatment with sulfadoxine – pyrimethamine (IPTp-SP) reduced the risk of these adverse events, 2 the World Health Organization (WHO) recommended IPTp-SP for all areas in Africa with moderate-to-high malaria transmission. 3 IPTp-SP is associated with significant reductions in low birthweight, with a protective efficacy of approximately 26% in an analysis of national survey data from 32 countries. 4 This impact has been presumed to be a result of the antimalarial effects of SP. Because resistance to SP has increased, particularly in eastern and southern Africa, SP is no longer recommended for treatment of acute malaria illness, even in combination with artemisinins. Despite this, even in areas where the efficacy of SP to clear parasitemia has clearly decreased, IPTp-SP has continued to show benefit for preventing low birthweight. 5 Moreover, no other antimalarials have yet been shown to be an ideal replacement for SP for IPTp. Studies evaluating potential alternative IPTp regimens have had mixed outcomes on birthweight, 6,7 leading to the hypothesis that SP may exert some of its effect through antibacterial or anti-inflammatory actions. 6 In Lusaka, Zambia, where malaria parasite prevalence is < 1%, Stoner and others show that among human immunodeficiency virus (HIV) – positive women, receipt of IPTp-SP was associated with a dose-dependent reduction
Self-efficacy in Anger Management and Dating Aggression in Italian Young Adults

An examination of the influence of self-efficacy regarding anger management on psychological and physical dating aggression using an agentic perspective of individual functioning. The investigation applied both the individual perspective (Study 1) and the interactional perspective (Study 2). The sample comprised 470 Italian young adults (223 females) (mean age across genders = 19.10; ds = 1.30) in study 1, and 62 couples in study 2 (mean age for males = 22.34; ds = 2.59; mean age for females = 19.58; ds = 1.50). The first study found that individuals’ efficacy regarding anger management affect dysfunctional behaviors toward the partner via couple conflict. The second study found that one partner’s efficacy regarding anger management affected couple conflict, which in turn affected the other partner’s psychological aggression. Results are discussed within an agentic framework of human development, where young adult partners are proactive agents of their own and their partners' behaviors, contributing actively to their intimate relationship adjustment rather than just re-acting to their partners’ behaviors.

Efficient construction of relational features

Devising algorithms for learning from multi-relational data is currently considered an important challenge. The wealth of traditional single-relational machine learning tools, on the other hand, calls for methods of 'propositionalization', i.e. conversion of multi-relational data into single-relational representations. A major stream of propositionalization algorithms is based on the construction of truth-valued features (first-order logic atom conjunctions), which capture relational properties of data and play the role of binary attributes in the resulting single-table representation. Such algorithms typically use backtrack depth first search for the syntactic construction of features complying to user's mode/type declarations. As such they incur a complexity factor exponential in the maximum allowed feature size. Here we present a polynomial-runtime alternative based on an efficient reduction between the feature construction problems on the propositional satisfiability (SAT) problem, such that the latter involves only Horn clauses and is therefore efficiently solvable.
The Construction, Negotiation, and Transformation of Racial Identity in American Football: A Study of Native and African Americans

L'A. considere la construction, la negociation et la transformation de l'identite raciale chez les Amerindiens et les Afro-Americains des Etats-Unis a travers la pratique du football, dans une etude qui va de 1890 aux annees 1960. Il part du principe que l'identite des individus est multiple : en tant qu'hommes, joueurs de football, membres de groupes raciaux et socioeconomiques differents, Americains, etc. Il analyse certains de ces roles qui sont en relation avec l'experience sportive des individus et les significations et interpretations qui en ont emerge dans la construction problematique de l'identite raciale, integrant des representations sur les differences physiques. La pratique de la culture blanche dominante fixait les cadres de l'interaction raciale et tendait a imposer les significations d'une identite raciale collective. Les Amerindiens et les Afro-Americains ont ainsi vecu des experiences similaires par l'exclusion, puis par une integration limitee dans la societe dominante. Ils ont aussi ete confrontes aux modeles des identites alternatives imposes par la societe blanche.
Integration of microstrip LP and BP filters to multilayer structure based on various LTCC

The aim of this paper lies in a design, simulation and integration of microstrip Band-Pass (BP) and Low-Pass (LP) filters into one multilayer package based on LTCC. In this article, we introduce five-section microstrip hairpin BP filter with a centre frequency of 7 GHz and a bandwidth of approx. 2 GHz and microstrip stepped-impedance LP filter with a cut-off frequency of 2.5 GHz. The paper presents simulated and measured results of mentioned filters' scattering parameters (S parameters) based on two different LTCC substrates (GreenTape 9K7X as well as GreenTape 951PX). Accent of this article was to investigate the impact of interlayer vias on microstrip LP filters' performances in the high frequency (HF) area. This paper shows a possibility of how to integrated two different types of filters in one multilayer module without mutual interference in HF area. The developed multilayer structure with integrated microstrip filters should be used as a part of I - Q (In-phase Quadrature) demodulator presented in [1].
Pancreatic fluid collections and necrosectomy with plastic stents versus lumen-apposing stents

The incidence of hospitalizations for acute pancreatitis is rising, with 5%–15% of patients with pancreatitis developing pancreatic fluid collections (PFCs). [1,2] In addition to acute pancreatitis, other causes of PFCs include chronic injury, trauma, surgical resection, and/or injury to the pancreas during abdominal surgery. [3,4] Management paradigms for these collections, particularly if they are complicated by infected necrosis, have changed over the past decade. Advances in endoscopic tools have driven a new era of minimally invasive techniques to manage both pancreatic pseudocysts (PPs) and walled-off necrosis (WON). This step-up approach with initial interventions using less invasive procedures rather than surgical necrosectomy was described by van Santvoort et al. and has been associated with an overall decreased mortality, fewer number of complications, and lower healthcare costs. [2,5] The primarily liquid content of PP can be drained in a single endoscopic session with a transmural drain to allow for collapse and resolution. However, the solid, necrotic tissue contained within WON often does not drain as easily and has the potential of developing infection, requiring larger caliber transmural drains. Therefore, successful management of PFCs must be tailored based on the characteristics of the collection.
Fusion rules and the Patera-Sharp generating-function method*

We review some contributions on fusion rules that were inspired by the work of Sharp, in particular, the generating-function method for tensor-product coefficients that he developed with Patera. We also review the Kac-Walton formula, the concepts of threshold level, fusion elementary couplings, fusion generating functions and fusion bases. We try to keep the presentation elementary and exemplify each concept with the simple c(2)k case.
The Changing Principalship: Its Current Status, Variability, and Impact

This article reports a study of the changing role of the principal in Washington State. Utilizing survey research, the findings reinforce role change and that the impact of changes vary between school levels and geographic location. In addition, the findings suggest that several aspects of role change for principals have resulted in principals reporting more hours worked, increasing managerial responsibilities supplanting leadership, and increased levels of frustration. In the midst of an environment of policy and social change, the role of the principal continues to be both important and under increasing strain. The article concludes with recommendations for policy makers and principal preparation and support.

Auxiliary Particle Filtering-Based Estimation of Remaining Useful Life of IGBT

Insulated gate bipolar transistor (IGBT) has been widely used in diverse power electronics systems. As IGBT is one of the most vulnerable components in power electronics converter, remaining useful life (RUL) estimation of this switch has become highlight of the research in recent years. This RUL estimation helps in schedule maintenance based on health status of IGBT to avoid the unexpected failure of converters. However, there has been commonly a large variance in RUL estimation due to presence of random noise, which leads to erroneous result in IGBT prognosis. To reduce this variance in RUL estimation, particle filter methods including sequential importance sampling and sequential importance resampling have been employed recently. Still, these methods lead to nonnegligible estimation variance due to degeneracy and impoverishment of samples. In this paper, RUL estimation approach based on auxiliary particle filter (APF) is proposed. The proposed method will sufficiently reduce estimation variance by increasing dimensionality of samples as well as by sustaining diversity in samples. In addition, a simple slope-based method is proposed to identify the region when the degradation is evident in IGBT. An APF method is applied when the IGBTs under test enter this region. This step is able to reduce variation in RUL estimation and computation cost. The performance of the proposed RUL estimation method is theoretically and experimentally verified.
Health and Quality of Life Outcomes

Background: To evaluate the psychometric properties of the Child-OIDP for use among children in the UK and report on the prevalence of oral impacts in a sample of schoolchildren in Westminster. Methods: Children aged 10–11 years in the final year of primary school (year 6) were selected from seven schools where annual screenings are carried out. A total of 228 children participated (99% response rate). A clinical examination was conducted followed by a questionnaire designed to measure oral health-related quality of life in children, namely the Child-OIDP. The psychometric properties of the Child-OIDP were evaluated in terms of face, content and concurrent validity in addition to internal and test-retest reliability. Results: The Child-OIDP revealed excellent validity and good reliability. Weighted Kappa was 0.82. Cronbach's alpha coefficient was 0.58. The index showed significant associations with perceived oral treatment needs and perceived satisfaction with mouth and oral health status (p < 0.001). Conclusion: This study has demonstrated that the Child-OIDP is a valid and reliable index to be used among 10–11 year old schoolchildren in the UK. Background The concept of need is central to planning, provision and evaluation of health care services. Traditionally, need has been estimated by using professionally based measures, known as normative need. Although normative need is important, it mainly reflects the clinical aspects of illness. However, subjective measures of health are important too, because they provide insights into how people feel and how satisfied they are with their quality of life [1]. Health-related quality of life instruments should therefore be used in conjunction with clinical measures. A child's oral health can impact on eating, smiling, speaking and socialising. Oral conditions, such as dental caries may result in pain, which in turn may lead to consequences on a child's daily life such as taking time off from school or difficulty eating.

Deploying a voice capture sensor network system for a secure ubiquitous home environment

In this paper we present a novel voice capture sensor network architecture proposal, we detail the implementation procedure that we followed to build a working prototype. The prototype is oriented toward a secure ubiquitous home environment but can be extended to other similar scenarios. Our approach is based on reducing data redundancy while maintaining node redundancy for reliability and providing at the same time basic security services without sacrificing a considerable amount of resources. We further show that our approach is energy‐efficient compared with the capture–send approach used traditionally. More importantly, through our experiences in the real‐world deployment of the system we also provide a roadmap for the development of efficient voice‐based smart home applications.
