Taxonomy of Hylotribus Jekel (Coleoptera: Anthribidae, Anthribinae): new synonymies, combinations and type designations
Authors: QUEIROZ FERNANDO ÁVILA , ELGUETA MARIO , MERMUDES JOSÉ RICARDO M.
Published: February 2017

The type material of six species of Anthribidae from Chile and one from Peru, originally described as Stenocerus Schoenherr and Stenorrhynchus Philippi & Philippi and later transferred to Hylotribus Jekel, was reexamined. These species are Stenocerus asperatus Blanchard, 1851, Stenocerus aspis Erichson, 1847, Stenocerus posticalis Philippi & Philippi, 1864, Stenocerus quadratipennis Germain, 1854, Stenorrhynchus quadrinotatus Philippi & Philippi, 1864, and Stenocerus tuberculosus Blanchard, 1851. Lectotype designations were made for Hylotribus asperatus, Hylotribus quadratipennis, and Hylotribus tuberculosus. New synonyms were established as follows: Hylotribus signatipes (Blanchard, 1851) = H. quadratipennis (Germain, 1854) syn. n., = H. quadrinotatus (Philippi & Philippi, 1864) syn. n., Hylotribus asperatus (Blanchard, 1851) = H. posticalis (Philippi & Philippi, 1864) syn. n.. While, Hylotribus aspis (Erichson, 1847) from Peru was transferred to Piesocorynus Dejean, 1834 and a new combination and synonymy proposed, Piesocorynus aspis (Erichson, 1847) n. comb. = Piesocorynus gracilicornis (Jekel, 1855) syn. n. The genus Hylotribus is defined with five species from Chile and six from Brazil, and the Chilean species are redescribed with illustrations. A new key to all species is included.

Hind wing morphology facilitates discrimination between two sibling species: Leiopus nebulosus and L. linnei (Coleoptera: Cerambycidae)
Authors: ROSSA ROBERT , GOCZAŁ JAKUB , TOFILSKI ADAM
Published: February 2017

The study focused on two sibling beetle species: Leiopus nebulosus (Linnaeus, 1758) and L. linnei Wallin, Nylander & Kvamme, 2009. These species are very similar morphologically and their identification is difficult and possible only by experienced taxonomists. A supporting method for identification of L. nebulosus and L. linnei based on hind wings measurements was developed. The study was based on 115 specimens of L. linnei and 45 specimens of L. nebulosus. The correctness of identification of L. nebulosus amounted to 95.56%, and of L. linnei – 97.39%. The obtained model facilitates reliable identification of L. nebulosus and L. linnei also by less experienced entomologists. Geographical distributions of both species were summarized based on faunistic data from 39 scientific papers. The results show that both species have a Western-Palearctic distribution. Their distribution ranges are markedly overlapping. However, L. linnei is the species reported from larger number of localities, and observed more often.
Geography, Race/Ethnicity, and Physical Activity Among Men in the United States
Authors: Sohn Elizabeth Kelley , Porch Tichelle , Hill Sarah , Thorpe Roland J.
Published: February 2017

Engaging in regular physical activity reduces one’s risk of chronic disease, stroke, cardiovascular disease, and some forms of cancer. These preventive benefits associated with physical activity are of particular importance for men, who have shorter life expectancy and experience higher rates of chronic diseases as compared to women. Studies at the community and national levels have found that social and environmental factors are important determinants of men’s physical activity, but little is known about how regional influences affect physical activity behaviors among men. The objective of this study is to examine the association between geographic region and physical activity among men in the United States, and to determine if there are racial/ethnic differences in physical activity within these geographic regions. Cross-sectional data from men who participated the 2000 to 2010 National Health Interview Survey ( N = 327,556) was used. The primary outcome in this study was whether or not men had engaged in sufficient physical activity to receive health benefits, defined as meeting the 2008 Physical Activity Guidelines for Americans. Race/ethnicity and geographic region were the primary independent variables. Within every region, Hispanic and Asian men had lower odds of engaging in sufficient physical activity compared to white men. Within the Northeast, South, and West, black men had lower odds of engaging in sufficient physical activity compared to white men. The key findings indicate that the odds of engaging in sufficient physical activity among men differ significantly between geographic regions and within regions by race/ethnicity.

Key Points

Apotransferrin decreases TfR1 expression and alters TfR1 trafficking to normalize enucleation in β-thalassemic erythroid precursors. Decreased TfR1 upregulates hepcidin in an iron- and ERFE-independent manner, resulting in iron-restricted β-thalassemic erythropoiesis.
Distinct functions of CXCR4, CCR2, and CX3CR1 direct dendritic cell precursors from the bone marrow to the lung
Authors: Nakano Hideki , Lyons-Cohen Miranda R , Whitehead Gregory S , Nakano Keiko , Cook Donald N
Published: February 2017

Precursors of dendritic cells (pre-DCs) arise in the bone marrow (BM), egress to the blood, and finally migrate to peripheral tissue, where they differentiate to conventional dendritic cells (cDCs). Upon their activation, antigen-bearing cDCs migrate from peripheral tissue to regional lymph nodes (LNs) in a manner dependent on the chemokine receptor, CCR7. To maintain immune homeostasis, these departing cDCs must be replenished by new cDCs that develop from pre-DCs, but the molecular signals that direct pre-DC trafficking from the BM to the blood and peripheral tissues remain poorly understood. In the present study, we found that pre-DCs express the chemokine receptors CXCR4, CCR2, and CX3CR1, and that each of these receptors has a distinct role in pre-DC trafficking. Flow cytometric analysis of pre-DCs lacking CXCR4 revealed that this receptor is required for the retention of pre-DCs in the BM. Analyses of mice lacking CCR2 or CX3CR1, or both, revealed that they promote pre-DC migration to the lung at steady state. CCR2, but not CX3CR1, was required for pre-DC migration to the inflamed lung. Thus, these multiple chemokine receptors cooperate in a step-wise fashion to coordinate the trafficking of pre-DCs from the BM to the circulation and peripheral tissues.
Matricellular proteins tune myeloid-derived suppressor cell recruitment and function in breast cancer
Authors: Chiodoni Claudia , Sangaletti Sabina , Colombo Mario P
Published: February 2017

Solid tumor progression is often associated with the expansion of myeloid-derived suppressor cells (MDSCs), a heterogeneous population of immature myeloid cells that actively foster tumor growth and metastatic dissemination through a plethora of mechanisms, including, but not limited to, their major suppressive activity on the immune response. Indeed, MDSCs may sustain tumor progression by dynamically remodeling the tumor microenvironment through the production of angiogenic factors and metalloproteases, by helping the establishment of a premetastatic niche, and by promoting stemness and epithelial-to-mesenchymal transition (EMT) features in tumor cells. MDSCs are also regulated by a growing list of factors that mainly comprise 2 sets of signals: those responsible for their expansion and recruitment, such as GM-, M-, and G-CSF and other growth factors, and those relevant for the induction of their suppressive activity, which include proinflammatory cytokines and transcription factors. We review here a new class of MDSC regulators—matricellular proteins—with a particular focus on osteopontin (OPN) and secreted acidic cysteine-rich glycoprotein (SPARC), which seem to affect the expansion/recruitment and the immune-suppressive activity of MDSCs. Matricellular proteins function indirectly on MDSCs through the induction of other mediators when produced by tumor cells and cell autonomously when expressed—likely in an intracellular form—directly by MDSCs.
Peer Effects in the Workplace
Authors: Cornelissen Thomas , Dustmann Christian , Schönberg Uta
Published: February 2017

Existing evidence on peer effects in the productivity of coworkers stems from either laboratory experiments or real-world studies referring to a specific firm or occupation. In this paper, we aim at providing more generalizable results by investigating a large local labor market, with a focus on peer effects in wages rather than productivity. Our estimation strategy—which links the average permanent productivity of workers' peers to their wages—circumvents the reflection problem and accounts for endogenous sorting of workers into peer groups and firms. On average over all occupations, and in the type of high-skilled occupations investigated in studies on knowledge spillover, we find only small peer effects in wages. In the type of low-skilled occupations analyzed in extant studies on social pressure, in contrast, we find larger peer effects, about one-half the size of those identified in similar studies on productivity.

The Impact of Family Income on Child Achievement: Evidence from the Earned Income Tax Credit: Reply
Authors: Dahl Gordon B. , Lochner Lance
Published: February 2017

Dahl and Lochner (2012) provides some of the first causal evidence of the effects of family income on child achievement using changes in the Earned Income Tax Credit. Unfortunately, a coding error in the creation of total family income affects the first stage estimates and inflates the instrumental variable (IV) estimates. Importantly, it does not affect the reduced-form estimates or alter statistical significance of the IV estimates. This response shows that correcting this error does not alter the core findings or main message of the paper. (JEL H24, H31, I21, I38, J13)
‘Where do you want to have your baby?’ Women's narratives of how they chose their birthplace
Authors: Woog Chantal Louise
Published: February 2017

Background

National guidelines endorse the provision of birthplace choice for women with low-risk pregnancies. Despite the availability of different options (birth centre, home and hospital) and substantial evidence highlighting the benefits of birth outside a hospital setting, the majority of women choose to give birth in a hospital.

Aims

This study aimed to: explore how low-risk, first-time mothers chose where to give birth to their babies; and gain an in-depth understanding of what factors influenced women's experiences of decision-making.

Methods

A qualitative study with a narrative approach was used. Data were collected using an online questionnaire. Participants were recruited from a social networking site. A purposive sample of nine low-risk, first-time mothers, all of whom were given a choice of birthplace (at least two options), was used.

Findings

Two core themes emerged that were considered to influence women's decisions on birthplace: women's expectations of birth, perception of safety and protecting the birthing process; and the influence of the midwife, antenatal education and the partner.

Conclusion

The study reveals that women make choices based on a variety of reasons. However, the findings presented suggest that most women give birth in a hospital as it is still widely considered to be the safest place for women and babies—both by couples themselves and by many health professionals. The challenge is to address this generation of women who believe that hospital is the most appropriate place to give birth, despite evidence to the contrary, and ultimately promote the normality of pregnancy and childbirth.
Cuban Internationalism and Contemporary Humanitarianism: History, Comparison and Perspectives
Authors: Marie Michèle Grenon
Published: February 2017

The end of the Cold War has introduced important transformations including the practice of humanitarian aid that adjusted to the new world order. The general tendencies of the ‘contemporary humanitarianism’ are well discussed in the scientific literature. Since 1959, Cuba has developed its internationalism policy and has created a post-disaster brigade relief in the late 1990s. However, the subject has been little studied. The objective of this article is to analyze the Cuban humanitarian practices, values and framework in comparison with the contemporary tendency that appears since the end of the Cold War. Based on interviews led with Cubancooperantesand a review of scientific literature, the study proposes that the Cuban post-relief internationalism is profoundly linked with the particular context in which it was created, but it is also functioning in a specific way in practice.

On the Astron UV Space Mission Data
Authors: Kilpio E. Yu. , Mironov A. V. , Malkov O. Yu.
Published: February 2017

The Soviet UV space mission Astron, launched in 1983, had been operational for eight years as the largest ultraviolet space telescope during its lifetime. Astron provided a lot of observational material for various types of astrophysical objects, but unfortunately these data were not widely available and, as a result, unduly forgotten. Here we present some results of our comparison of the Astron data to the modern UV stellar data, such as the NGSL spectral library, discuss the precision and accuracy achieved with Astron, and make some conclusions on potential application areas of these data.
A New Revision of the HDEC (Henry Draper Extension Charts) Catalog
Authors: Ashimbaeva N. , Sementsov V.
Published: February 2017

A new version of the HDEC (Henry Draper Extension Charts) catalog is presented. The catalog includes 88,548 entries, more than 3500 of which (components of binary systems) were earlier corrupted by an algorithmic error (1579 multiple systems were revealed). Spectral classification of these objects has been corrected manually using the CDS data. We also corrected some mistakes of the catalog detected by the measurement model and cross-matching with other CDS catalogs, and, in some cases, by the authors of the catalog and through collaboration of the HDEC users.
Half a Century after the Outburst of the Symbiotic Nova V1016 Cyg
Authors: Arkhipova V. P. , Taranova O. G. , Ikonnikova N. P. , Esipov V. F. , Komissarova G. V. , Shenavrin V. I.
Published: February 2017

We present the results of our long-term UBV JHKLM photometry and spectroscopic monitoring of the symbiotic nova V1016 Cyg. After its outburst in 1964, the star showed fading in the U, B, V bands at a rate of about 0.03 mag per year. The behavior of the B − V and U − B color indices reflects variations of the emission lines, fading of the erupted component, weakening and reddening of the cool giant. Also, monotonic color and brightness variations in the infrared (IR) were observed at a scale of several thousand days. After 2004, the yearly mean IR brightness showed a decline and IR colors, reddening, due to the increase of the optical depth of the dust. The parameters of the cool star and of the dust envelope were estimated. The pulsation period of the Mira-type variable was refined, P = 465±5 days. The Mira’s photospheric temperature varied from 2100 to 2700 K in the pulsation cycle. The mass of the dust shell has grown twice during the recent decade, at a dust penetration rate of ∆M
dust ~ 10−7
M
⊙/yr. Our spectroscopic monitoring of V1016 Cyg over 1995−2013 showed variations in the emission line strengths. The absolute fluxes of most lines decreased after 2000, whereas the relative intensities of [O III], [Ar III], [Fe VII], [Ca VII] lines with respect to Hβ are increasing after the possible minimum that could happen in the 1990s. An essential flux decline (approximately ten-fold between 1995 and 2013) in the Raman scattered O VI line at λ6825 shows the change of conditions in its formation zone, due to absorption of O VI 1032 Å quanta in the new dust shell of the cool component.
Stäackel-type Dynamic Model of the Galaxy Based on Maser Kinematic Data
Authors: Gromov A. O. , Nikiforov I. I. , Ossipkov L. P.
Published: February 2017

A dynamic model of the Galaxy is constructed based on kinematic data for masers with trigonometric parallaxes. Maser data is used to compute the model potential in the Galactic plane. The potential is then generalized to three dimensions assuming the existence of a third quadratic integral of motion. The resulting Galactic model potential is of Stäckel’s type. The corresponding space density function is determined from Poisson’s equation.

A project for astrometric and photometric observations of asteroids with the VATT telescope on Mt. Graham is described. One of the most important results is the discovery of the Transneptunian object (420356) Praamžius. We computed its orbit applying 198 optical observations from 2003 February 1 to 2016 January 30. We also followed its orbit searching for minimal distances to Neptune between the years 17 000 and −13 000. Combined with the apparent brightness, the orbit gives the absolute magnitude
Phase-Space Model of a Collisionless Stellar Cylinder Embedded in a Rotating Halo
Authors: Kondratyev B. P. , Kireeva E. N.
Published: February 2017

The phase-space model of a stellar cylindrical bar embedded in a rotating triaxial halo is constructed. The equations of motion of an individual star in the bar are derived and solved. The model has three integrals of motion and the condition of the cylinder boundary conservation is derived. The model is found to represent a four-dimensional ellipsoid in six-dimensional phase space. The phase-space distribution function of stars is derived, which depends on isolating integrals of motion. The centroid velocity field describes longitudinal shear averaged flows in the cylinder. Two non-zero components of the velocity dispersion tensor depend quadratically on coordinates and vanish at the surface of the cylindrical bar.
Kernel Density Estimation in the Study of Star Clusters
Authors: Seleznev Anton F.
Published: February 2017

The kernel estimator method is used to evaluate the surface and spatial star number density in star clusters. Both density maps and radial density profiles are plotted. These estimates are used to derive the cluster size, the number of cluster stars and the cluster mass, and to study the cluster structure. The kernel estimator is also used to plot the luminosity function, mass function, the velocity distribution, and Hess diagrams for star clusters. The advantages of the kernel estimator method and technical details of its use are illustrated by modern results for the open cluster NGC 4337.
Swing Amplification and Global Modes Reciprocity in Models with Cusps
Authors: Polyachenko E. V.
Published: February 2017

We use 3D N-body simulations to analyze the onset of the bar in cuspy models, and argue that the role of swing amplification is twofold. Amplified shot noise due to disk discreteness hampers the bar formation, while induced resonance perturbations allow the bar amplitude to overcome shots. The bar pattern speed and the growth rate obtained in N-body simulations agree well with the global mode analysis.

Critical comments to a recent EFLM recommendation for the review of reference intervals
Authors: Haeckel Rainer , Wosniok Werner , Arzideh Farhad , Zierk Jakob , Gurr Eberhard , Streichert Thomas
Published: February 2017

In a recent EFLM recommendation on reference intervals by Henny et al., the direct approach for determining reference intervals was proposed as the only presently accepted “gold” standard. Some essential drawbacks of the direct approach were not sufficiently emphasized, such as unacceptably wide confidence limits due to the limited number of observations claimed and the practical usability for only a limited age range. Indirect procedures avoid these disadvantages of the direct approach. Furthermore, indirect approaches are well suited for reference limits with large variations during lifetime and for common reference limits.
Erudite, Insightful and Immensely Important: A Commentary on V. P. Glăveanu’s Critical Article The Psychology of Creativity – a Critical Reading
Authors: Persson Roland S.
Published: February 2017

Glăveanu’s target article is indeed timely and thought provoking. This commentary argues that Glăveanu needs not to be criticised in regard to stances taken, but rather be encouraged to expand his scope further. I suggest that this should be done by addressing the need for inter-disciplinary knowledge synthesis and also by recognising and exploring the social dynamics (and politics) of the academic world. Researchers need to be knowledgeable with regard to both in order to further an understanding of creativity and also to apply research findings responsibly.
The Big Question in Creativity Research: The Transcendental Source of Creativity
Authors: Kharkhurin Anatoliy V.
Published: February 2017

In this commentary, I raise an etiological question, which has been virtually excluded from the horizon of contemporary scholarship. In spite of a long history of philosophical, mystical, and religious approaches considering the transcendent and/or spiritual sources of human creativity, mainstream creativity researchers have become gradually reluctant to acknowledge the supernatural influences in this human endeavour. This account is either disregarded altogether or re-interpreted in a way that substitutes supernatural connections with observable and measurable processes. On the one hand, the latter approach appears to fall within the premises of modern science and thereby earns substantial attention the scientific community. On the other, this could be one of the reasons why creativity research has reached its epistemological cul-de-sac. I argue that by retaining the source of creativity within an individual, one annihilates the whole constellation of personality traits and processes, which have transcendent characteristics. It is important to integrate the study of transcendent experience into the study of cognitive, personality, and environmental underpinnings of creative faculties. A possible direction for this change is offered by transpersonal psychology, which makes an attempt to resurrect an investigation of spiritual reality and integrate it in the study of modern psychology. At the end of the commentary, I sketch a transcendental model of creativity developed along the lines of a transpersonal paradigm.
Cognitive Poetry: Theoretical Framework for the Application of Cognitive Psychology Techniques to Poetic Text
Authors: Kharkhurin Anatoliy V.
Published: February 2017

This article presents a theoretical framework for the author’s experimental work in contemporary poetry, which has received the term cognitive poetry. In contrast to cognitive poetics, which applies the principles of cognitive psychology to interpret poetic texts, cognitive poetry applies these principles to produce poetic texts. The theoretical considerations of cognitive poetry are based on the assumption that one of the major purposes of creative work is to elicit an aesthetical reaction in the beholder. The aesthetical reaction to poetic texts could be achieved via their satiation with multiple meanings presented through multiple sensory modalities. Cognitive poetry employs techniques developed in cognitive psychology to explicitly address cognitive processes underlying the construction of multiple conceptual planes. The following techniques are discussed: priming, the Stroop effect, multimodal and multilingual presentations. The applications of these techniques are illustrated with examples of poetic texts produced by the author.
Slumps and Jumps: Another Look at Developmental Changes in Creative Abilities
Authors: Gralewski Jacek , Lebuda Izabela , Gajda Aleksandra , Jankowska Dorota M. , Wiśniewska Ewa
Published: February 2017

The aim of this study is the analysis of creativity changes across life, particularly the widely discussed crisis periods in the development of creative abilities. A large and diversified sample of Poles (N = 4898 aged from 4 to 21 years), at each educational stage of the Polish education system, from pre-schoolers, through primary school students, middle-school students, secondary-school students and finally university students completed the Test for Creative Thinking – Drawing Production. The observed changes showed a nonlinear pattern in the development of creativity with diverse declines and increases in creative abilities. These trends are different for each of the assessment criteria of the TCT-DP and at least three different trajectories were identified. The adolescent slump was confirmed for three of the 14 assessment criteria as well as the total TCT-DP score. What was not noted however was: a slump caused by entry into formal schooling, (age 6 vs 7), 4th grade slump, (age 9 vs 10) and 6th grade slump (age 11 vs 12). We discuss possible reasons for and consequences of the findings.
Teachers’ Beliefs About Creativity and Possibilities for its Development in Polish High Schools: A Qualitative Study
Authors: Gralewski Jacek
Published: February 2017

The aim of the present study was to research teachers’ beliefs about creativity and possibilities for its development in Polish high schools. The study consisted of in-depth interviews. It was conducted with a group of 15 high school teachers, all of whom taught the key subjects (math, Polish and foreign languages) for the final school-leaving examination. The qualitative thematic analysis applied to the collected data revealed eight themes. Each of them concerned the teachers’ understanding of what creativity really is, their attitude towards students’ creative activity at school, aims that they formulated to stimulate their creativity, as well as the role and place of students’ creative activity at school. In addition, the themes referred to actions that had been taken by the teachers to stimulate their students’ creativity and factors that inhibited or stimulated the development of students’ creativity at school. The teachers, who were the subject of the analysis, understood creativity as creative potential, that is, the ability to think independently, to give new and original solutions to all sorts of tasks and problems, as well as creative activity oriented towards everyday innovation. Additionally, the study revealed that there exists a creativity gap between verbal support for developing students’ creativity at school and classroom practice.
Love for Frequent and Low Flow Activities in the United States and India
Authors: Montijo Monica N. , Mouton Angela R.
Published: February 2017

This study explored how much participants in the United States (US) and India loved activities that are inherently flow producing (Frequent Flow Activities) versus those that are not (Low Flow Activities). Frequent Flow Activities (FFA) typically possess the three antecedents of flow, namely clear and proximate goals, immediate feedback and a perceived balance of challenge and skill. By contrast, Low Flow Activities (LFA) are typically relaxing or enjoyable but not underpinned by these antecedents. In addition, this study explored whether love for FFA/LFA differed by age, gender and nationality, and whether love for FFA/LFA was positively related to various measures of wellbeing. Results indicate that neither age nor gender affected love for FFA/LFA. However, nationality did make a difference, in that Indian but not US participants loved FFA more than LFA. Finally, both FFA/LFA were significantly and positively related to a number of wellbeing measures. Implications and applications are discussed.
Placing and Preserving Labor History
Authors: Donaldson Rachel
Published: February 2017

This article focuses on the significance of sites and landscapes of labor history in public history, particularly in the fields of preservation and interpretation. Through the preservation of labor history sites, public historians can educate various audiences about the diversity of the working-class experience in the United States. Although sites of work have long been identified as historically significant, all too often the workers have been excluded from these narratives. By understanding which sites are important in working-class history and by bringing workers’ voices into the act of protecting, commemorating, and interpreting sites of labor, we can achieve a more inclusive view of labor history—one that connects these stories to the national narrative and illustrates the centrality of labor and labor activism to American history.
An unusual case of adult-onset multi-systemic Langerhans cell histiocytosis with perianal and incident thyroid involvement

Published: February 2017

Langerhans cell histiocytosis (LCH) is a rare sporadic disease characterized by histiocytic neoplastic infiltration of various organ systems and a wide spectrum of clinical manifestations, ranging from benign and self-limiting to lethal. Herein, we report a rare case of adult-onset multi-systemic LCH in a 36-year-old male patient with an initial perianal presentation and incidental finding of subsequent thyroid gland involvement in the follow-up period. The patient with a history of perianal LCH treated with surgical excision and local radiotherapy was referred to our Endocrinology Department upon detection of hypermetabolic nodular lesions in the left lateral lobe of thyroid gland on positron emission tomography–computed tomography (PET/CT) scan in the nineth month of follow-up. Current evaluation revealed euthyroid status, a hypoechoic solid lesion of 13 × 9 mm in size with irregular borders in the left thyroid lobe on thyroid USG and cytologic assessment of thyroid nodule. The patient was diagnosed with suspected, oncocytic lesion, Hashimoto thyroiditis or LCH. The patient underwent total thyroidectomy and pathological assessment confirmed the diagnosis of Langerhans cell histiocytosis. Assessments in the sixth month of postoperative follow-up revealed euthyroid status with no thyroid tissue remnants or pathological lymph node on thyroid USG. In view of the multifocal lesions indicating multi-system disease, a systemic chemotherapy protocol with combination of prednisone (PRED) and vinblastine (VBL) has been planned by the hematology department.

Learning points:

Langerhans cell histiocytosis (LCH) shows a wide clinical spectrum and prognosis that ranges from benign and self-limiting single-system disease (with single or multifocal lesions) to a potentially lethal multi-system disease with severe organ dysfunction and death in some cases.

It has been stated that the diagnosis is often delayed in perianal LCH unless LCH is specifically considered in the etiology, despite the fact that mucosal involvement may precede systemic involvement.

Our findings support the statement that most of patients with LCH were PET positive at the time of initial diagnosis, while also emphasize the inclusion of this imaging modality as a part of the diagnostic workflow as well as in the setting of treatment response evaluation among adult LCH patients.
Silencing the roadblocks to effective triple-negative breast cancer treatments by siRNA nanoparticles
Authors: Parvani Jenny G , Jackson Mark W
Published: February 2017

Over the past decade, RNA interference (RNAi) has been ubiquitously utilized to study biological functionin vitro; however, limitations were associated with its utilityin vivo. More recently, small interfering RNA (siRNA) nanoparticles with improved biocompatibility have gained prevalence as a potential therapeutic option for the treatment of various diseases. The adaptability of siRNA nanoparticles enables the delivery of virtually any siRNA, which is especially advantageous for therapeutic applications in heterogeneous diseases that lack unifying molecular features, such as triple-negative breast cancer (TNBC). TNBC is an aggressive subtype of breast cancer that is stratified by the lack of estrogen receptor/progesterone receptor expression andHER2amplification. There are currently no FDA-approved targeted therapies for the treatment of TNBCs, making cytotoxic chemotherapy the only treatment option available to these patients. In this review, we outline the current status of siRNA nanoparticles in clinical trials for cancer treatment and discuss the promising preclinical approaches that have utilized siRNA nanoparticles for TNBC treatment. Next, we address TNBC subtype-specific therapeutic interventions and highlight where and how siRNA nanoparticles fit into these strategies. Lastly, we point out ongoing challenges in the field of siRNA nanoparticle research that, if addressed, would significantly improve the efficacy of siRNA nanoparticles as a therapeutic option for cancer treatment.

Comorbidities and Complications of Spinal Fusion for Scoliosis
Authors: Berry Jay G. , Glotzbecker Michael , Rodean Jonathan , Leahy Izabela , Hall Matt , Ferrari Lynne
Published: February 2017

BACKGROUND AND OBJECTIVES:

General pediatricians and hospitalists are increasingly summoned to optimize the comorbid conditions of children with medical complexity (CMC) undergoing major surgery. We assessed the relationship between specific chronic conditions of CMC and hospital resource use with spinal fusion for scoliosis, an operation with high cost and morbidity.

METHODS:

Retrospective analysis of 7252 children age ≥5 years with an underlying complex chronic condition undergoing spinal fusion between January 1, 2010 through December 31, 2014 in 41 children’s hospitals. Hospital length of stay (LOS), cost, and 30-day readmission rate were compared across comorbid conditions by using linear and logistic regression accounting for demographic characteristics and clustering of patients by hospital.

RESULTS:

Fifty-nine percent of children had ≥4 comorbid conditions. As the number of chronic conditions increased from 1–3 to ≥10, median LOS increased 60% (5 [interquartile range (IQR), 4–7] to 8 [IQR, 5–13] days); median hospital cost increased 53% ($52 319 [IQR, $37 937–71 513] to $80 429 [IQR, $58 602–$111 965]); and readmission rates increased 293% (5.4% to 15.8%) (P < .001 for all). In multivariable analysis, conditions strongly associated with LOS and cost were chronic respiratory insufficiency (LOS: +2.1 days; cost: +$12 070; and bladder dysfunction (LOS: +0.8 days; cost: +$4014) (P < .001 for all). Readmission likelihood was highest with bladder dysfunction (odds ratio, 1.5; 95% confidence interval, 1.1–2.0) and epilepsy (odds ratio, 1.2; 95% confidence interval, 1.0–1.5).

CONCLUSIONS:

Chronic respiratory insufficiency, bladder dysfunction, and epilepsy had significant associations with hospital resource use for CMC undergoing spinal fusion. Pediatricians, patients, and families may find it useful to consider these conditions when striving to benefit the children’s perioperative health and outcomes.

Malaria menyebabkan sekitar 350-500 juta infeksi pada manusia dengan sekitar satu hingga tiga jutaÂ kematian per tahun di seluruh dunia. Malaria pada pelancong tejadi sekitar 30.000 kasus impor setiap tahun diÂ negara-negara industri non-endemis. Salah satu upaya pencegahan terbaik yang dapat dilakukan pada infeksiÂ ini adalah dengan cara vaksinasi. Vaksinasi pra-eritrositer RTS,S dari permukaan sporozoit PlasmodiumÂ falciparum terus dikembangkan untuk mencapai efikasi yang memuaskan. RTS,S diharapkan dapat diberikanbagi orang yang bertempat tinggal di daerah endemis maupun bagi pelancong yang hendak berpergian keÂ daerah endemis malaria. RTS,S dikombinasikan dengan sistem adjuvan untuk meningkatkan respon imun. HasilÂ uji klinis fase 2b RTS,S/AS02 menunjukkan hasil yang menjanjikan. Fase 3 uji klinis RTS,S/AS01 yang mulaiÂ dilakukan pada tahun 2009 telah melaporkan hasil pertama uji klinis pada akhir tahun 2011. Efikasi yangÂ dicapai oleh RTS,S/AS02 dalam mengurangi risiko malaria pada anak menunjukkan angka 62%. EfikasiRTS,S/AS01 sebesar 55,8% terhadap kasus infeksi malaria baru pada kelompok anak usia 5-17 bulan. PadaÂ kelompok yang menggabungkan kedua kelompok usia yaitu, 5-17 bulan dan 6-12 minggu, Efikasi vaksinÂ RTS,S/AS01 terhadap malaria berat pada kelompok usia yang digabungkan ini adalah 34,8%. Efikasi RTS,S/AS01Â dinilai menjanjikan dan akan dikembangkan untuk di masa mendatang sebagau imunoprofilaksis padaÂ pelancong.

The prevalence of dental caries in those with age more than 12 years old in Indonesia reaches 46, 5%. From the prevalence we could see that the majority of students in Indonesia have dental caries. According to RISKESDAS 2007 data, it is said that 91, 1% of Indonesian citizen with age more than 10 years old does brush their teeth every day, but only 7, 3% of them that brush their teeth 2 times a day at the right time which is in the morning after breakfast and at night before bedtime. At Rendang Public Health, dental caries is one of the top 10 diseases of the year 2013. Because of that, this study is done to know the description of tooth brushing habit towards incidence of dental caries because tooth brushing is an important habit for dental caries prevention.
Obraz świata zakładany w pytaniach filozoficznych – na przykładzie fenomenologii (Ingarden) i tomizmu egzystencjalnego (Krąpiec)
Authors: Duchliński Piotr
Published: February 2017

W artykule przedstawiono, w jaki sposób za pomocą analizy pytań oraz udzielanych na nie odpowiedzi można dokonać eksplikacji zakładanego przez filozofów obrazów świata. Problem ten przedyskutowano na przykładzie tomistów i fenomenologów. Analiza pytań oraz udzielanych odpowiedzi pokazała, że za każdym sformułowanym pytaniem kryje się inny obraz świata, który decyduje o tym, jakie pytania się stawia w punkcie wyjścia teorii oraz jakich udziela się odpowiedzi. Wszystkie pytania i odpowiedzi są zawsze zrelatywizowane do określonego obrazu świata, który filozof przyjmuje, kierując się różnymi racjami: metodologicznymi, aksjologicznymi czy też społecznopsychologicznymi. W przypadku fenomenologów mamy do czynienia z platońskim obrazem świata, zaś w przypadku tomistów z obrazem arystotelesowskim.
’Aκρασία and desire
Authors: Hynes Timothy
Published: February 2017

Although he does not use the phrase, in Book VII of the Nicomachean ethics, Aristotle contends with the philosophical problem of socratic intellectualism, attempting to unwind the apparent paradox of the ἀκρατής, the man who knows what he ought to do and who fails to do it. As part of this project, he examines the mechanism of the practical syllogism, knowledge in terms of potency and act, as well as ignorance and knowledge. In this essay, I will briefly review Aristotles’ endeavor, emphasizing the role of desire in the practical syllogism. By taking apart the example syllogism he uses, I will argue that desire plays a fundamental role in the deliberative process and functions as a kind of implicit universal premise. In doing so, I will show the interaction between reason and desire and the way in which the latter plays a pivotal part in the conclusion of the practical syllogism. Finally, insofar as desire can be understood as one of the premises of the syllogism and thus a kind of ‘knowledge,’ I will conclude by arguing that moral development consists in reason determining the proper mean for each of the virtues, and that it has an important role in cultivating the emotions, ordering them to the principles of practical wisdom.

This paper investigates the organizational climate from the perspective of the psychological needs of workers; in the absence of studies tend to find processes for improving the mental health of workers in organizations. This work allowed delving into the psychological implications of workers within organizations that do not prioritize generating a motivating organizational climate. In a stratified sample of 350 two Ecuadorian workers, public and private organizations, the measurement scale of organizational climate adapted by Chiang (2011), authors Koys & DeCotiis, (1991) is applied, and the psychological implications workers through an instrument based on questionnaires (MBIGS), (BMS II) and (CAT 21). Organizational factors that affect and relations the quality of life of workers in organizations and labor relation context with being at work are discussed.Este trabajo investiga el clima organizacional desde la perspectiva de las necesidades psicológicas de los trabajadores, ante la carencia de estudios que tiendan a buscar procesos de mejoramiento de la salud psicológica de los trabajadores en las organizaciones, permitiendo profundizar en las implicaciones psicológicas de los trabajadores dentro de organizaciones que no dan prioridad a la generación de un clima organizacional motivador, con muestra de 350 trabajadores de dos organizaciones ecuatorianas: una pública y una privada, se aplica la escala de medición del clima organizacional adaptada por Chiang (2011), de los autores Koys & DeCotiis (1991), y las implicaciones psicológicas en los trabajadores a través de un instrumento, basado en los cuestionarios (MBIGS), (BMS II) y (CAT 21).
