Percutaneous Closure of a Coronary Artery-to-Vein Graft Anastomotic Pseudoaneurysm Presenting as Acute Coronary Syndrome after Recent Coronary Artery Bypass Grafting
Authors: Maybrook Ryan J. , Sharma Suresh , Gupta Kamal , Wiley Mark , Parashara Deepak
Published: June 2015

Pseudoaneurysm formation has been reported in degenerated coronary artery saphenous vein bypass grafts, as well as in native coronary arteries after interventional procedures or blunt trauma. In contrast, pseudoaneurysm formation arising from the anastomotic site of native coronary vessels soon after coronary artery bypass grafting is rare, and neither the clinical presentation of this phenomenon nor its treatment is well described.

We present the case of a 63-year-old man, a recent coronary artery bypass grafting patient, who presented with acute coronary syndrome due to a large and expanding pseudoaneurysm of the saphenous vein-to-ramus intermedius artery graft anastomosis. After several attempts, we successfully treated the pseudoaneurysm by means of percutaneous coil embolization. To our knowledge, this is the first report of acute coronary syndrome secondary to a pseudoaneurysm at the coronary artery–saphenous vein graft anastomosis. In addition, this appears to be the first report of the percutaneous treatment of such a pseudoaneurysm by means of coil embolization.
Sinus Pause in Association with Lyme Carditis
Authors: Oktay A. Afsin , Dibs Samer R. , Friedman Harvey
Published: June 2015

Lyme disease is the most prevalent tick-borne disease in the United States. It is caused by the spirochete Borrelia burgdorferi. Cardiac involvement is seen in 4% to 10% of patients with Lyme disease. The principal manifestation of Lyme carditis is self-limited conduction system disease, with predominant involvement of the atrioventricular node. On rare occasions, Lyme carditis patients present with other conduction system disorders such as bundle branch block, intraventricular conduction delay, and supraventricular or ventricular tachycardia. We report the unusual case of a 59-year-old man who presented with new-onset symptomatic sinus pauses one month after hiking in upstate New York. To our knowledge, this is the first case report from North America that describes the relationship between symptomatic sinus pause and Lyme carditis.
Possible Role for Cryoballoon Ablation of Right Atrial Appendage Tachycardia when Conventional Ablation Fails
Authors: Amasyali Basri , Kilic Ayhan
Published: June 2015

Focal atrial tachycardia arising from the right atrial appendage usually responds well to radiofrequency ablation; however, successful ablation in this anatomic region can be challenging. Surgical excision of the right atrial appendage has sometimes been necessary to eliminate the tachycardia and prevent or reverse the resultant cardiomyopathy. We report the case of a 48-year-old man who had right atrial appendage tachycardia resistant to multiple attempts at ablation with use of conventional radiofrequency energy guided by means of a 3-dimensional mapping system. The condition led to cardiomyopathy in 3 months. The arrhythmia was successfully ablated with use of a 28-mm cryoballoon catheter that had originally been developed for catheter ablation of paroxysmal atrial fibrillation. To our knowledge, this is the first report of cryoballoon ablation without isolation of the right atrial appendage. It might also be an alternative to epicardial ablation or surgery when refractory atrial tachycardia originates from the right atrial appendage.
Motion Verbs in Old Saxon with the Oblique Subject Construction: A Semantic Analysis
Authors: Dewey Tonya Kim , Arnett Carlee
Published: June 2015

An interesting fact about Old Saxon is that certain verbs of motion can occur with a dative pronoun which shows certain properties often considered to be indicative of subject status, making these verbs part of the dative subject construction. The dative marked argument is always animate and usually human. Punctuality and telicity are also often overtly marked in the clause. The dative occurs with verbs of motion in Old Saxon when the participant is salient in the discourse. In some instances, a nominative subject earlier in the discourse can trigger verb agreement, but very often a nominative simply is not present. Additionally, the dative pronoun is in subject position next to the finite verb. Thus the dative with verbs of motion exhibits the subject properties of linear subject position, topicality, animacy, definiteness and discourse salience. Semantic subject properties include volitionality, initiation of action, telicity and punctuality. Our analysis concludes that the dative argument with verbs of motion is related, but not identical, to other non-nominative subjects attested in Old Saxon.
Economical Activity Of The Polish Population
Authors: Bieszk-Stolorz Beata , Markowicz Iwona
Published: June 2015

The aim of the article is to examine the impact of a job seeker’s gender, education, age on their employment odds in Poland in 2011. The research includes Polish population which was economically active and aged 15 and more in 2011 (17,951 thousand people). The research tool was a logit model. The starting point for the analysis was the construction of a model that related employment to gender only. Then other models with many explanatory variables were constructed. Since the gender related odds ratios that have been determined for the sake of those models are interpreted under the assumption that the other variables are constant, it indicates that the women’s and men’s odds ratio remains the same in urban and rural areas, on every education level and in every age group. But in reality it is not true. This is why we estimated the models that contained only one explanatory variable (gender) for individual subgroups and models with the interactions.

Authors: Dębski Wiesław , Feder-Sempach Ewa , Świderski Bartosz
Published: June 2015

In the modern portfolio theory investment risk plays a crucial role. It is the subject of numerous studies and publications, in particular in relation to the management of investment portfolios. Commonly used measure of investment management in equities is a beta parameter, which is used to estimate individual stock risk and portfolio risk. In particular, numerous studies the subject of which are the beta parameter properties such as stability in the context of the stock market cycle phases, intervalling effect, length estimation sample etc. The main objective of this paper is to investigate the intervalling effect on the beta parameter. The empirical analysis is carried out for the 33 largest companies of the Warsaw Stock Exchange (WSE) on a sample from the years 2005 to 2012 on the basis of daily, weekly and monthly rates of return. Statistical verification of the hypothesis of the importance of the frequency measuring the return of shares will be based on the single-index Sharpe’s model.
Finasteride, not tamsulosin, increases severity of erectile dysfunction and decreases testosterone levels in men with benign prostatic hyperplasia
Authors: Traish Abdulmaged M. , Haider Karim Sultan , Doros Gheorghe , Haider Ahmad
Published: June 2015

Background:5α-reductase inhibitors (5α-RIs) (finasteride and dutasteride) have been proven useful in treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH). However, these inhibitors exert undesirable sexual side effects and, in some cases, these effects are persistent. There is considerable disagreement with regard to whether the adverse side effects resolve with continuous treatment.

Aim:To investigate the long-term adverse effects of finasteride treatment in men with BPH on erectile function and to compare these adverse effects in men treated with the α1-adrenergic receptor blocker, tamsolusin.

Methods:In this retrospective registry study, a cohort of 470 men aged between 47 and 68 years (mean 57.78±4.81) were treated with finasteride (5 mg/day). A second cohort of 230 men aged between 52 and 72 years (mean 62.62±4.65) were treated with tamsulosin (0.4 mg). All men were followed up for 45 months. At intervals of 3 months and at each visit, plasma testosterone (T) levels and the international index of erectile function (IIEF-EF) questionnaire scores were determined.

Results:Long-term treatment with finasteride therapy is associated with worsening of erectile dysfunction (ED) as shown by the significant decrease in the IIEF-EF scores in men treated with finasteride. No worsening of ED was observed in men treated with tamsulosin. The increase in ED due to finasteride did not resolve with continued treatment with finasteride. Most importantly, long-term finasteride therapy resulted in reduction in total T levels, contributing to a state of hypogonadism. On the contrary, no changes in T levels were noted in men treated with tamsolusin.

Conclusion:Our findings suggest that in men with BPH, long-term finasteride therapy but not tamsulosin results in worsening of ED and reduces total T concentrations. Clinicians are urged to discuss the impact of 5α-RIs therapy on sexual function with their patients before commencing this therapy.
The assembly and disassembly of the AcrAB-TolC three-component multidrug efflux pump
Authors: Müller Reinke Tobias , Pos Klaas Martinus
Published: June 2015

In Gram-negative bacteria, tripartite efflux pumps, like AcrAB-TolC from Escherichia coli, play a prominent role in the resistance against multiple antibiotics. Transport of the drugs across the outer membrane and its coupling to the electrochemical gradient is dependent on the presence of all three components. As the activity of the E. coli AcrAB-TolC efflux pump is dependent on both the concentration of substrates and the extent of the electrochemical gradient across the inner membrane, the dynamics of tripartite pump assembly and disassembly might be crucial for effective net transport of drugs towards the outside of the cell.
Merging Interactive Information Filtering and Recommender Algorithms – Model and Concept Demonstrator
Authors: Loepp Benedikt , Herrmanny Katja , Ziegler Jürgen
Published: June 2015

To increase controllability and transparency in recommender systems, recent research has been putting more focus on integrating interactive techniques with recommender algorithms. In this paper, we propose a model of interactive recommending that structures the different interactions users can have with recommender systems. Furthermore, as a novel approach to interactive recommending, we describe a technique that combines faceted information filtering with different algorithmic recommender techniques. We refer to this approach as blended recommending. We also present an interactive movie recommender based on this approach and report on its user-centered design process, in particular an evaluation study in which we compared our system with a standard faceted filtering system. The results indicate a higher level of perceived user control, more detailed preference settings, and better suitability when the search goal is vague.

Ambiguity Resolution In Precise Point Positioning Technique: A Case Study
Authors: Nistor S. , Buda A. S.
Published: June 2015

Because of the dynamics of the GPS technique used in different domains like geodesy, near real-time GPS meteorology, geodynamics, the precise point positioning (PPP) becomes more than a powerful method for determining the position, or the delay caused by the atmosphere. The main idea of this method is that we need only one receiver – preferably that have dual frequencies pseudorange and carrier-phase capabilities – to obtain the position. Because we are using only one receiver the majority of the residuals that are eliminated in double differencing method, we have to estimate them in PPP. The development of the PPP method allows us, to use precise satellite clock estimates, and precise orbits, resulting in a much more efficient way to deal with the disadvantages of this technique, like slow convergence time, or ambiguity resolution. Because this two problem are correlated, to achieve fast convergence we need to resolve the problem of ambiguity resolution. But the accuracy of the PPP results are directly influenced by presence of the uncalibrated phase delays (UPD) originating in the receivers and satellites. In this article we present the GPS errors and biases, the zenith wet delay and the necessary time for obtaining the convergence. The necessary correction are downloaded by using the IGS service.
Scheduling And Simulation Of VLBI Measurements For The Determination Of Earth Orientation Parameters
Authors: Nistor S. , Buda A. S.
Published: June 2015

The article aims to present the results obtain from the scheduling and simulation of VLBI measurements in October 2010 for a period of three days for 24 hour continuous observations. To be sure that we will obtain good VLBI observation we have to do an optimization of the network. This can be done quite accurately by using the new modules that are part of the VLBI processing software’s, the modules scheduling and simulation. This can be considered the first step in preparation of the VLBI experiment. Very Long Baseline Interferometry (VLBI) it is a primary space-geodetic technique that it is able to determine precise coordinates on the Earth, by monitoring the variable of Earth orientation parameters (EOP) with high precision. Also Very Long Baseline Interferometry plays an important role for determination of celestial and terrestrial reference frame. It is also a technique that each year is more developed form a software and hardware point of view. To obtain the scans we used a set of eight different VLBI antennas and as a source we used different quasars. In the scheduling we used the source based strategy contrary to the station based approach and the radio sources where from updated catalogues according to the requirements of the VLBI2010 system, which means that we are able to obtain a best coverage of the celestial sphere. The results show that scheduling and simulation are very good tools in preparing real VLBI experiments.

Published: June 2015

Purpose of the research is to examine coordination in disaster response by computer simulation using Petri net. We addressed issues on coordination in disaster response by focusing on interorganizational processes. Defining the processes according to disaster exercise, we developed the model based on Stochastic Petri Net. Index items, including average delay time and busyness probability, were introduced to facilitate discussion. Simulation demonstrated utilization of process analysis in performance assessment of collaborative disaster response. Since fragmentation is critical factor hindering efficient response, its remedy or elimination should be focused for system optimization.
Multigene phylogeny reveals three new records of Colletotrichum spp. and several new host records for the mycobiota of Iran
Authors: Arzanlou Mahdi , Bakhshi Mounes , Karimi Keivan , Torbati Mohsen
Published: June 2015

The genus Colletotrichum comprises a number of plant pathogens of major importance which cause anthracnose diseases on a wide range of woody and herbaceous plants worldwide. With the advent of molecular studies, it has been shown that most of the previously known species e.g. C. boninense, C. acutatum, and C. gloeosporioides have been split into several species. In the present study, the identity of Colletotrichum isolates from the northern and northwestern zone of Iran were determined based on multi-gene phylogenetic analyses. Phylogenetic analysis based on a combination of internal transcribed spacer (ITS), beta tubulin (TUB), histone H3 (HIS), calmodulin (CAL), and actin (ACT) loci, clustered our isolates into three clades, including C. salicis on Salix sp., Colletotrichum sp. (C. fuscum sensu lato) within the C. destructivum species complex on Viola sp., and C. fructicola on Citrus sinensis, Malus domestica, Gleditsia caspica, and Sambucus ebulus. These three species are new for mycobiota of Iran. According to these results, Viola sp. from West Azerbaijan (Khoy-Firouragh) is a new host for Colletotrichum sp. in the C. destructivum species complex. Furthermore, C. sinensis from Mazandaran (Behshahr), and G. caspica, and S. ebulus from Guilan (Talesh), are new host records for C. fructicola.

“They Say One Thing and Mean Another” How Differences in In-Group Understandings of Key Goals Shape Political Knowledge
Authors: Vähämaa Miika , West Mark D.
Published: June 2015

Journalists and politicians play different roles in the functional structure of the Habermasian public sphere; as such, they might be expected to have different understandings of what knowledge production and transmission might mean. This difference of understanding is more than a conflict over definitions; it is an epistemic divergence à la Fuller (2002:220), where already defined groups hold divergent understandings of what constitutes understanding. While a substantial body of work has been based on the idea of epistemic communities in the context of science and expert organizations in general, little empirical research exists to demonstrate the validity and adaptability of the concept of epistemic communities in comparative political communication research. Here, we show the cross-national validity of the concept of epistemic communities in the context of professional groups of politicians and political journalists in Austria, Finland, France, Denmark, Germany, Slovenia, Spain, Sweden and Switzerland.
Aggressive or Peaceful Rise? An Empirical Assessment of China’s Militarized Conflict, 1979–2010
Authors: Xiang Jun , Primiano Christopher B. , Huang Wei-hao
Published: June 2015

The recent years have witnessed a heated debate on China’s rise. Using various theoretical arguments, existing research has generated quite divergent conclusions on whether China rises peacefully. Liberals argue that China has significantly benefited from the existing international economic system and therefore China is rising peacefully. On the other hand, realists such as John Mearsheimer argue that because China is likely to challenge the status quo, a rising China poses a threat to international security. Surprisingly, despite the ample scholarship on this topic and the existing divergent conclusions, a large-N empirical evaluation of China’s rise is missing in the existing research. This study fills this important gap by providing a large-N empirical investigation of militarized interstate disputes between China and other states from 1979 to 2010. We find that although China’s GDP, military spending, and CINC score have increased remarkably since the start of its economic reform, no empirical evidence points to more conflicts between China and other states. Furthermore, trade exerts only a weak effect on China’s conflict, a surprising yet interesting finding that revises the conventional wisdom in the literature.

Authors: Wojcieszak Damian , Mazur Michał , Kaczmarek Danuta , Morgiel Jerzy , Poniedziałek Agata , Domaradzki Jarosław , Czeczot Aleksandra
Published: June 2015

Titanium dioxide thin films doped with the same amount of neodymium were prepared using two different magnetron sputtering methods. Thin films of anatase structure were deposited with the aid of Low Pressure Hot Target Magnetron Sputtering, while rutile coatings were manufactured using High Energy Reactive Magnetron Sputtering process. The thin films composition was determined by energy dispersive spectroscopy and the amount of the dopant was equal to 1 at. %. Structural properties were evaluated using transmission electron microscopy and revealed that anatase films had fibrous structure, while rutile had densely packed columnar structure. Atomic force microscopy investigations showed that the surface of both films was homogenous and consisted of nanocrystalline grains. Photocatalytic activity was assessed based on the phenol decomposition. Results showed that both thin films were photocatalytically active, however coating with anatase phase decomposed higher amount of phenol. The transparency of both thin films was high and equal to ca. 80% in the visible wavelength range. The photoluminescence intensity was much higher in case of the coating with rutile structure.

Authors: Otten Kathrin A. , Littmann Klaus , Fege Ragna L. , Oremek Xenia
Published: June 2015

This study evaluates the suitability of electrical resistance-based moisture content measurements, which are known to guarantee reliable values for moisture contents of wood, when applied to selected mineral building materials with and without water-repellent treatment. For the testing specimens of cement – mortar and solid brick were produced – the water-repellent treatment for the mortar specimens was carried out both by internal hydrophobization and surface treatment, while the bricks were hydrophobized by surface treatment only. For the measurements of electrical resistance electrodes were inserted into the specimens. For this purpose a borehole was drilled and the measuring point at the tip of the electrodes was glued conductively into the material. The remaining outer part of the electrodes was sealed with electrically isolating glue in order to establish a conductive connection in the middle of the specimens only. After storage at different relative humidity, the electrical resistance of the specimens was recorded using data logging devices. Based on gravimetrically measured moisture contents resistance characteristics for each material were established. A satisfying accuracy resulting from the comparison between gravimetrically measured and mathematically calculated material moisture contents confirmed the suitability of electrical resistance based moisture content measurements for selected treated and untreated mineral materials.
Capillary Absorption and Chloride Penetration into High-Performance Fiber-Reinforced Cement-Based Composites (HPFRCC) as Influenced by Tensile Stress and Self-Healing
Authors: Wittmann Folker H. , Wang Penggang , Zhang Peng , Zhao Tiejun
Published: June 2015

High-performance fiber-reinforced cement-based composites (HPFRCC) can be characterized by low porosity and fine pores as compared to normal concrete and therefore this interesting material absorbs little water or aqueous salt solutions if exposed to aggressive environment. These properties are indications for excellent durability and long service life of structural members or structures made with this high-performance material. In practice, however, most structures and structural elements are designed to be load bearing. The influence of an applied tensile stress on capillary absorption was investigated and results are presented in this contribution. It was found that the coefficient of capillary absorption increases rapidly if a tensile stress exceeding half of the tensile strength is applied. This observation has to be taken into consideration if HPFRCC is to be applied in aggressive environment. The maximum admissible stress must be reduced accordingly.
Mathematical modelling of the within-host HIV quasispecies dynamics in response to antiviral treatment
Authors: Bocharov Gennady A. , Telatnikov Ilya S. , Chereshnev Valery A. , Martinez Javier , Meyerhans Andreas
Published: June 2015

The aim of this work is the construction, calibration, and comparative analysis of mathematical models of the evolution of the human immunodeficiency virus (HIV) in the course of infection when the models are based on deterministic principles of the quasispecies theory (Eigen-Schuster) and on stochastic approaches of genetic algorithms (Holland). The models take into account the replication of viral genomes and selection of descendants according to their fitness, point mutations, multi-infection of target cells and recombination of genomes at the stage of formation of proviral DNA. The processes of diversification of the virus population under the action of the antiviral drug azidothymidine (AZT) that blocks reverse transcription of the virus are simulated. A four-letter alphabet is used in the stochasticmodel for description of nucleotide sequences. The parameters of the model are estimated using original data on the degree of adaptation of the HIV mutants that are partly or completely resistant to this drug. The influence of parameters of infection on the characteristics of viral mutants population diversity is studied
Once again, Erich Przywara and the Jews: A response to John Betz with a brief look into the Nazi correspondences on Przywara and Stimmen der Zeit
Authors: Peterson Paul Silas
Published: June 2015

In this article, I respond to John Betz (University of Notre Dame, USA) who has recently rejected claims that I have made about Erich Przywara’s anti- Semitism and his relationship to Nazi era ideology. Although I admire much of Przywara’s theology and have great sympathy for the teaching about the analogy of being, in this article I address some of the problems of Przywara’s work. I address literature from Przywara on the Jews where he talks about the essence of “the Jew” as “restless” and “revolutionary,” and where he brings up the “wandering Jew” theme or claims Judaism is an “insolent disturber” of the (German) “folkdom.” Przywara’s rejection of “Jewish messianism” and his claims about the “basic tension of the Jew” are also addressed. I analyze his conception of the essence of “the Jew” as, among other things, a “rising will of destruction” and his claim that “Christianity” ultimately becomes the “enemy” of Judaism. Beyond these things, Przywara’s desire to “overcome” Judaism with the right “weapons” is addressed. I also draw attention to his rejection of “Jewish capitalism” and his justification of “the hatred towards the Jews in world history.” In addition to this, his use of ideologically charged Nazi terminology, such as “host-peoples,” and his support of Catholic integralism in Nazi Germany are addressed. Furthermore, Przywara’s remarks (to a leading Nazi representative and ideologue, Hanns Johst) on “the positive sense” of the German “movements” (i. e. National Socialism) in the 1930s are presented. I also show that Przywara”s work was praised by a leading representative and ideologue of National Socialism (Otto Dietrich). With this, I address the internal Nazi correspondences on the very influential German Catholic Jesuit journal titled Stimmen der Zeit
Power Corrupts: Karl Barth’s Use of Jacob Burckhardt’s Philosophy of History
Authors: Jimenez Michael
Published: June 2015

This essay traces the influence of the nineteenth century Swiss historical school led by the historian Jacob Burckhardt upon the thought of the theologian Karl Barth. Barth utilizes the unseasonable thoughts of Burckhardt and Nietzsche to critique the optimistic philosophy of history based in Berlin. Burckhardt’s suspicion of power is especially important for Barth as they both disagree with Nietzsche’s fascination with power and Hegel’s optimistic historical reason. However, Barth’s mature ideas about history are almost exclusively focused on God’s revelation in Christ, distancing himself from Burckhardt’s overtly pessimistic reading of history. The paper closes asking if Barth ever successfully navigates away from Hegelian historical reason
Transfer Annealing in Chromic-Doped Potassium Chromate
Authors: Apers D. J. , Collins K. E. , Collins C. H. , Ghoos Y. F. , Capron P. C.
Published: June 2015

Thermal treatment on chromic (51Cr)-doped potassium Chromate results in the incorporation of 51Cr activity into the Chromate form. Measurements of the isothermal kinetics of this incorporation give "annealing" curves similar to those obtained in Szilard-Chalmers studies on potassium Chromate. It is concluded that transfer annealing may play an important role in Szilard-Chalmers annealing processes in potassium Chromate.
The Mechanism of Molecule-Formation by Nuclear Fission and Subsequent Processes in Solid Mixtures
Authors: Baumgärtner F. , Schön A.
Published: June 2015

Experiments at temperatures from 4° K up to 500° K show that, at least in the case of -formation from uranium fission products and a suitable target Compound in the solid phase, i. e.

neither impact substitution by primary fission recoil

nor unstable intermediate products

nor normal chemical reactions

nor thermal radical reaction

nor radiation induced reactions

play any part.

The only origin of molecule formation is the β-decayof the fission product atoms and the role of primary fission recoil is only to transport the atoms inside the admixed target-compound. Furthermore it is shown by using target-compounds with different central atoms for substitution, i.e. Fe(C5H5)2, Ru(C5H5)2, Os(C5H5)2, that the molecule formation process is not a high energy recoil process but occurs in an energy range where chemical bond-strengths of the target material are significant.

La influencia de las noticias periodísticas en las actitudes morales de las audiencias: el análisis lingüístico de Ch. L. Stevenson y J. Searle

La influencia de los mensajes periodísticos en la (trans)formación de las actitudes morales se considera más que probable, pero su estudio empírico conseguirá unas conclusiones válidas sólo si se apoya en una sólida base filosófica. Ella es imprescindible para elaborar una definición de lo moral que permita desarrollar hipótesis y variables para la investigación de campo. El marco más adecuado parece ofrecer el emotivismo de Ch. L. Stevenson combinado con la teoría de la intencionalidad de J. Searle, porque establece un puente conceptual entre el análisis teórico del fenómeno moral y las regularidades de la formación de las actitudes, recogidas en las teorías de rango medio de la Cognición Social (teorías de persuasión) y de la Psicología Moral (teorías de la moral universal). Sólo con una síntesis teórica que abarque el proceso en su totalidad puede plantearse la pregunta sobre la influencia de las noticias periodísticas en él.DOI  http://dx.doi.org/10.15304/ag.34.2.2141

Animal movement constraints improve resource selection inference in the presence of telemetry error
Authors: Brost Brian M. , Hooten Mevin B. , Hanks Ephraim M. , Small Robert J.
Published: June 2015

Multiple factors complicate the analysis of animal telemetry location data. Recent advancements address issues such as temporal autocorrelation and telemetry measurement error, but additional challenges remain. Difficulties introduced by complicated error structures or barriers to animal movement can weaken inference. We propose an approach for obtaining resource selection inference from animal location data that accounts for complicated error structures, movement constraints, and temporally autocorrelated observations. We specify a model for telemetry data observed with error conditional on unobserved true locations that reflects prior knowledge about constraints in the animal movement process. The observed telemetry data are modeled using a flexible distribution that accommodates extreme errors and complicated error structures. Although constraints to movement are often viewed as a nuisance, we use constraints to simultaneously estimate and account for telemetry error. We apply the model to simulated data, showing that it outperforms common ad hoc approaches used when confronted with measurement error and movement constraints. We then apply our framework to an Argos satellite telemetry data set on harbor seals (Phoca vitulina) in the Gulf of Alaska, a species that is constrained to move within the marine environment and adjacent coastlines.

Background: This study assesses the effects of topical sodium alendronate (SA) as an adjuvant to the mechanical treatment of ligature‐induced periodontitis in rats.

Methods: Ninety animals were subjected to the induction of periodontitis via the installation of a ligature around the mandibular left first molar. After 7 days, the ligature was removed, and the animals were distributed into the following groups: 1) NT group (n = 30), no treatment; 2) SRP group (n = 30), scaling and root planing (SRP) and local irrigation with physiologic saline solution; and 3) SRP/SA group (n = 30), SRP and local irrigation with SA (10−5 M). Ten animals from each group were euthanized at 7, 15, and 30 days after treatment. Histologic and histometric analyses were performed in the furcation region. The percentage of bone in the furcation (PBF) was measured. Immunohistochemical analyses for detecting the receptor activator of nuclear factor‐κB ligand (RANKL), osteoprotegerin (OPG), tartrate‐resistant acid phosphatase (TRAP), and activated caspase‐3 were performed at the furcation region.

Results: Compared with the other groups, the SRP/SA group showed less local inflammation and better tissue reparation during the entire experiment. There was more PBF in the SRP/SA group than in the other groups at days 7 and 15. Stronger OPG immunolabeling and weaker RANKL immunolabeling were observed in the SRP/SA group at 15 and 30 days. There were fewer TRAP‐positive cells in the SRP/SA group than in the NT group at all of the time points. There was no difference in the number of activated caspase‐3‐positive osteocytes among groups and time points.

Conclusion: It can be concluded that topical use of SA as an adjuvant to SRP is effective in the treatment of experimental periodontitis.

Objectives. We examined the association between the size and growth of Latino populations and hospitals’ uncompensated care in California.

Methods. Our sample consisted of general acute care hospitals in California operating during 2000 and 2010 (n = 251). We merged California hospital data with US Census data for each hospital service area. We used spatial analysis, multivariate regression, and fixed-effect models.

Results. We found a significant association between the growth of California’s Latino population and hospitals’ uncompensated care in the unadjusted regression. This association was still significant after we controlled for hospital and community population characteristics. After we added market characteristics into the final model, this relationship became nonsignificant.

Conclusions. Our findings suggest that systematic support is needed in areas with rapid Latino population growth to control hospitals’ uncompensated care, especially if Latinos are excluded from or do not respond to the insurance options made available through the Affordable Care Act. Improving availability of resources for hospitals and providers in areas with high Latino population growth could help alleviate financial pressures.
Effects of Participation and Collaboration on Perceived Effectiveness of Core Public Health Functions
Authors: Sinclair Amber , Whitford Andrew
Published: June 2015

Objectives. We measured the perceived effectiveness of core public health services at the community level, and we assessed whether certain system factors were associated with perceived effectiveness.

Methods. We used data from the National Longitudinal Survey of Local Public Health Systems, conducted in 1998 and 2006, to examine the effects of the contributions of health departments and the participation of other agencies to core functions on the perceived effectiveness of community delivery of core assessment, policy development, and assurance functions.

Results. Perceived effectiveness increased over time for all 3 core function areas (range = 41%–53% in 2006). Multivariable results showed that local health department contribution to effort was positively associated with perceived effectiveness of public health core functions. The significance of participation of individual types of agencies or organizations varied by core function areas, except for local government agencies and hospitals, which were significantly positively associated with all 3 core function areas.

Conclusions. We furthered our understanding of the significance of the contributions and participations of local health departments and of other individual agencies or organizations in the perceived effectiveness of delivery of core functions.
Association Between Connecticut’s Permit-to-Purchase Handgun Law and Homicides

Published: June 2015

Objectives. We sought to estimate the effect of Connecticut’s implementation of a handgun permit-to-purchase law in October 1995 on subsequent homicides.

Methods. Using the synthetic control method, we compared Connecticut’s homicide rates after the law’s implementation to rates we would have expected had the law not been implemented. To estimate the counterfactual, we used longitudinal data from a weighted combination of comparison states identified based on the ability of their prelaw homicide trends and covariates to predict prelaw homicide trends in Connecticut.

Results. We estimated that the law was associated with a 40% reduction in Connecticut’s firearm homicide rates during the first 10 years that the law was in place. By contrast, there was no evidence for a reduction in nonfirearm homicides.

Conclusions. Consistent with prior research, this study demonstrated that Connecticut’s handgun permit-to-purchase law was associated with a subsequent reduction in homicide rates. As would be expected if the law drove the reduction, the policy’s effects were only evident for homicides committed with firearms.
Black Lives Matter: A Commentary on Racism and Public Health
Authors: Jee-Lyn García Jennifer , Sharif Mienah Zulfacar
Published: June 2015

The recent nonindictments of police officers who killed unarmed Black men have incited popular and scholarly discussions on racial injustices in our legal system, racialized police violence, and police (mis)conduct. What is glaringly absent is a public health perspective in response to these events.

We aim to fill this gap and expand the current dialogue beyond these isolated incidents to a broader discussion of racism in America and how it affects the health and well-being of people of color.

Our goal is not only to reiterate how salient structural racism is in our society, but how critical antiracist work is to the core goals and values of public health.

Published: June 2015

Objectives. We assessed the impact of trying electronic cigarettes (e-cigarettes) on future cigarette smoking in a sample of smokers enrolled in college.

Methods. In this longitudinal study, first-semester college students at 7 colleges in North Carolina and 4 in Virginia completed a baseline survey and 5 follow-up surveys between fall 2010 and fall 2013. Current cigarette smoking at wave 6 was the primary outcome. Participants (n = 271) reported current cigarette smoking at baseline and no history of e-cigarette use. We measured trying e-cigarettes at each wave, defined as use in the past 6 months.

Results. By wave 5, 43.5% had tried e-cigarettes. Even after controlling for other variables associated with cigarette smoking, trying e-cigarettes was a significant predictor of cigarette smoking at wave 6 (adjusted odds ratio [AOR] = 2.48; 95% confidence interval [CI] = 1.32, 4.66), as were friends’ cigarette smoking (AOR = 4.20; 95% CI = 2.22, 7.96) and lifetime use of other tobacco products (AOR = 1.63; 95% CI = 1.22, 2.17).

Conclusions. Trying e-cigarettes during college did not deter cigarette smoking and may have contributed to continued smoking.

Authors: Yamazaki Hiroshi , Akaoka Yusuke , Komatsu Masatoshi
Published: June 2015

Case:

Injury of the axillary artery after shoulder-joint fracture or dislocation is uncommon. We describe the clinical outcome of an elderly patient with a dissecting aneurysm of the axillary artery following open reduction of a fracture-dislocation of the shoulder. The arterial dissection was successfully managed with percutaneous transluminal balloon angioplasty.

Conclusion:

This case report highlights the need for careful vascular examination of all elderly patients with a fracture or dislocation of the shoulder and the possible use of percutaneous transluminal angioplasty for the management of arterial dissection prior to proceeding with surgical exploration.
The Use of Telephone Help-lines by Lonely Children and Adolescents
Authors: Campbell Marilyn
Published: June 2015

Loneliness is a subjective distressing feeling of being disconnected from a desired group or intimate relationship. Most children and adolescents experience loneliness at some time but for 10-20% of young people it can be severe and chronic. While there are many avenues for help for distressed young people, such as friends and family as well as the professional help of counselors and psychologists, lonely young people often do not seek help. Telephone help-lines are one way to assist young people in difficulty which is cost effective, accessible and anonymous. Many countries provide this free or low cost help with specific services for youth either by telephone or online. From the call records of help-lines however, it would seem that lonely young people do not often utilize these services. The reasons for this apparent reluctance are discussed.
