EFFECT OF EMOTIONAL INTELLIGENCE COMPETENCIES ON ACADEMIC PERFORMANCE AMID COLLEGE STUDENTS: A STRATEGIC APPROACH
Authors: S. Ramesh  , Dr H. Samuel Thavaraj  , Dr Well Haorei  , Dr D. Ramkumar
Published: February 2021

Cognitive ability alone is no longer the highest standard by which companies assess college graduates. Non-cognitive ability, such as emotional intelligence (EI), is an essential skill that distinguishes the potential high-performance students. It is hypothesized that high academic performing students will also display more EI levels than students with more modest academic achievement. The present study aims to review the studies conducted across the globe to explore the impact of EI's fundamental components, namely personal and social competencies on academic performance among the college students. The current literature reviews found a growing area of research into EI's necessary competencies and its relationship with academic performance among the students. The study reveals that a high level of personal and social competencies results in increased academic performance and vice versa. Research work done by various researchers shows a positive and significant relationship exists between the EI competencies (personal and social competencies) with the academic performance of the college students.

Honour and Fighting Social Advancement in the Early Modern Age
Authors: Gassmann Jürg
Published: February 2021

The article considers the importance of military service in social advancement, here understood as filling the role of “prince” in feudal law and thus participating in the government of an estate, in the transition from the Late Middle Ages to the Renaissance or Early Modern Age. In the context of a city burgher or a petty noble or knight advancing into a government role, did honour require that the individual have experience in fighting – in war, military organisation and leadership? How did mercenaries figure? What role, if any, did Fechtmeister, Fechtbücher, Fechtschulen or Kriegsbücher play?
On the convergence of solutions of variational problems with pointwise functional constraints in variable domains
Authors: Kovalevsky Alexander
Published: February 2021

We consider a sequence of convex integral functionals $F_s:W^{1,p}(\Omega_s)\to\mathbb R$
and a sequence of weakly lower semicontinuous and, in general, nonintegral functionals
$G_s:W^{1,p}(\Omega_s)\to\mathbb R$, where $\{\Omega_s\}$
is a sequence of domains in $\mathbb R^n$ contained in a bounded domain
$\Omega\subset\mathbb R^n$ ($n\geqslant 2$) and $p>1$.
Along with this, we consider a sequence of closed convex sets
$V_s=\{v\in W^{1,p}(\Omega_s): M_s(v)\leqslant 0\,\,\text{a.e.\ in}\,\,\Omega_s\}$,
where $M_s$ is a mapping from $W^{1,p}(\Omega_s)$ to the set
of all functions defined on $\Omega_s$.
We establish conditions under which minimizers and minimum values
of the functionals $F_s+G_s$ on the sets $V_s$ converge
to a minimizer and the minimum value of a functional on the set
$V=\{v\in W^{1,p}(\Omega): M(v)\leqslant 0\,\,\text{a.e.\ in}\,\,\Omega\}$,
where $M$ is a mapping from $W^{1,p}(\Omega)$ to the set
of all functions defined on $\Omega$.
Distribution of random motion at renewal instants in three-dimensional space
Authors: Pogorui Anatoliy , Rodrĭguez-Dagnino Ramón
Published: February 2021

In physics, chemistry, and mathematics, the process of Brownian motion is often identified with the Wiener process that has infinitesimal increments. Recently, many models of Brownian motion with finite velocity have been intensively studied. We consider one of such models,
namely, a generalization of the Goldstein--Kac process to the three-dimensional case with the Erlang-2 and Maxwell--Boltzmann distributions of velocities alternations. Despite the importance of having a three-dimensional isotropic random model for the motion of Brownian particles, numerous research efforts did not lead to an expression for the probability of the distribution of the particle position, the motion of which is described by the three-dimensional telegraph process. The case where a particle carries out its movement along the directions determined by the vertices of a regular $n+1$-hedron in the $n$-dimensional space was studied in \cite{Samoilenko}, and closed-form results for the distribution of the particle position were obtained. Here, we obtain expressions for the distribution function of the norm of the vector that defines particle's position at renewal instants in semi-Markov cases of the Erlang-2 and Maxwell--Boltzmann distributions and study its properties. By knowing this distribution, we can determine the distribution of particle positions, since the motion of a particle is isotropic, i.e., the direction of its movement is uniformly distributed on the unit sphere in ${\mathbb R}^3$. Our results may be useful in studying the properties of an ideal gas.

Fibonacci Tavşan Problemi önemli bir sayı dizisi olan Fibonacci dizisini vermektedir. Bu dizi incelendiğinde karşılaşılan indirgeme bağıntısının karakteristik denklemi 2. dereceden bir polinom denklem olduğu görülür. Bu dizinin ardışık terimlerinin oranının limiti ise bu 2. derece polinom denklemin köklerinden biri olan Fi sayısına yakınsar. Peki neden Fi sayısına yakınsar? Sadece pozitif kök olduğu için mi? Bu çalışmada tavşan problemindeki bazı veriler değiştirilmiştir. Değiştirilen veriler “Canlının yetişkinliğe ulaşma süresi” ve “Canlının yetişkinliğe ulaştıktan sonra hangi aralıklarla doğum yaptığı”dır. Bu değişkenlerin aldıkları değerlere göre ortaya, farklı indirgeme bağıntıları çıkmıştır. Bu indirgeme bağıntılarının karakteristik denklemlerinin 2. dereceden daha yüksek mertebelerde polinomlar oldukları görülmüştür. Bu dizilerin karakteristik denklemi olan Polinom denklemlerin köklerinden birinin Fibonacci dizisinde uygulanan algoritmada olduğu gibi “Dizinin ardışık terimlerin oranlarının limiti” ile bulunabileceği gösterilmiştir. “Bu durumda oluşan dizinin ardışık terimlerin oranının limit değeri her zaman bir köke yakınsar mı? Hangi köke yakınsar? Bu metot hangi koşullar altında sağlanır?” sorularına cevap verilmiştir. Bu çalışmada yüksek mertebeden polinom denklemlerin köklerinden mutlak değerce en büyük kök reel ise bu reel kökün bulunması için bir metot ortaya koyulmuştur. Bu metot aynı zamanda polinom denklemlerin reel kökleri için üst veya alt sınır bulunmasına da katkı sağlamaktadır.

Published: February 2021

BPR memiliki peranan yang besar untuk mendorong perekonomian daerah, namun kontribusi BPR dewasa ini relatif masih kecil. Dari segi perkembangan ROA dan ROE, BPR di DKI Jakarta dan Banten relatif tidak lebih unggul dibandingkan provinsi lainnya di Pulau Jawa, sementara kedua daerah berada dekat dengan pusat ekonomi nasional.  Hal itu menunjukkan bahwa kinerja BPR di kedua provinsi tersebut belum dapat dikatakan superior. Hal itu diduga berkaitan dengan adanya permasalahan dalam strategi bersaing dan kreasi nilai. Sehingga penelitian ini bertujuan untuk menguji pengaruh kreasi nilai dan strategi bersaing terhadap kinerja BPR di DKI Jakarta dan Banten. Data dikumpulkan melalui kuesioner terhadap 50 responden dan dianalisis dengan menggunakan PLS. Hasil penelitian menunjukkan bahwa kreasi nilai memiliki pengaruh yang lebih tinggi dibandingkan strategi bersaing dalam mempengaruhi kinerja BPR di DKI Jakarta dan Banten. Temuan ini diharapkan menjadi model alternatif solusi bagi manajemen BPR di DKI Jakarta dan Banten, bahwa peningkatan kinerja BPR bertumpu pada pengembangan kreasi nilai terutama dalam penciptaan business partner, yang ditunjang dengan pengembangan strategi bersaing.

Numerical Analysis of the Improving Thermal Energy Efficiency of Taylor-couette Flow
Authors: Abdelmlek Khaoula Ben , Nejma Fayçal Ben
Published: February 2021

This paper deals with adimensionnal analysis of natural convection in a horizontal cylindrical annulus. The inner cylinder is isothermally heated and rotates with an angular velocity Ω, however the outer one is kept cold and motionless. The gap between cylinders is defined by an adimensional radius ratio f. The numerical study was carried out using COMSOL Multiphysics. The effects of Rayleigh number ranging from 102 to 106, radius ratio and rotation velocity on the flow pattern and the thermal behavior in the annulus are then elaborated. Particular attention is paid to the effect of different parameters on the local Nusselt numbers on the inner and outer cylinders, the mean Nusselt number and the energy efficiency of the process. Results show that the mean Nusselt number increases with the increase of Rayleigh number. However, it decreases with the increase of the radius ratio f because of the narrowing of the annulus. The results prove also that the heat transfer rate drops with the rise of rotation velocity. Finally, it was found that the energy efficiency achieved its maximum for lower Rayleigh numbers Ra=103, and lower rotation velocities.

Authors: Varganov M. V. , Miklichev A. A. , Bogdanov K. D.
Published: February 2021

The influence of various schemes of preoperative preparation for autodermoplasty on the rates of skin graft survival and the duration of hospitalization in patients with burns and wounds of various etiologies was analyzed. Patients were divided into groups and subgroups depending on the preparation scheme. Group I (22 patients) received negative pressure wound therapy (NPWT) during the preoperative period for 5 days in combination with reamberin — intravenous drip at a rate of 40-60 drops/min, 500 ml, once a day for 5 days. Those patients were divided into subgroups: subgroup 1A (17 people) received complex treatment without antibiotic therapy, subgroup 1B (5 people) received antibiotic therapy. Group II consisted of 30 patients, who received vacuum therapy during the preparatory period. Group II patients were also divided into subgroups: 2A (16 people) received NPWT without antibiotics, 2B (14 people) — vacuum therapy together with antibiotic therapy. Group III (comparison, n=52) included patients who were treated using traditional methods, including antibiotic therapy and topical use of various dressings and ointments. Follow-up morphohistological study of wound biopsies was carried out in order to determine the area of fibroblasts, the area of fibroblast nucleus, and the number of vessels. After skin autografting, skin flap survival rate was determined, taking the time of hospitalization into account. Upon comparison of preoperative preparation schemes used for patients with burns and chronic ulcers of various etiologies with a surface area of 1–5% appropriate for skin autografting, the scheme that included NPWT and reamberin for 5 days proved to be the most effective: an improvement in fibroblastogenesis and blood flow to the wound was noted in this group of patients, which was accompanied by an improvement in the skin flap survival rate up to 90.0±9.9%, which, in turn, reduced the duration of patient’s hospital stay — the average duration of the preoperative period was 2.5 times shorter, postoperative — 1.9 times shorter than in the comparison group (p<0.05). The results obtained make it possible to recommend the use of this scheme in the preoperative preparation for skin autografting for patients with burns and chronic ulcers of various etiologies with the surface area of 1–5%.

Roberto Gerhard y el ballet Don Quixote
Ampliando el mito
Authors: Walshaw Trevor
Published: February 2021

Roberto Gerhard consideró siempre la novela de Cervantes, Don Quijote de la Mancha, «como su Biblia», según narra su amigo David Drew; resulta, además, muy significativo que cuando Gerhard marchara al exilio, al final de la Guerra Civil, una de las primeras obras que compusiera estuviera basada precisamente en esta novela. Gerhard recreó la obra de Cervantes de tal forma que sugiere que su línea de pensamiento estaba en sintonía con las de filósofos como Miguel de Unamuno, Ortega y Gasset y Salvador de Madariaga, los cuales usaban la novela como medio para interpretar los problemas de España en época de crisis. Unamuno fue el primero que creó su propio quijotismo en 1905; le siguieron Ortega y Gasset en 1914 y Madariaga en 1926. La novela de Cervantes (o Benengeli) fue reinterpretada en la obra de estos y otros pensadores hasta adquirir los atributos de un mito antiguo. La evidencia de la relación de Gerhard con los escritores seleccionados está basada en que el hecho de que poseía sus libros y en que las ideas de sus trabajos aparecen y desaparecen del argumento del ballet, a través de lo que, junto a la música, articula su propio quijotismo mediante un sistema serial creado para el propio ballet. La expresión del catolicismo se evoca a través de la aparición de Dulcinea en el paso de Semana Santa y en el uso del cantus firmus. En la creación del ballet, por lo tanto, Gerhard añadió más conceptos mitológicos (y filosóficos) a los héroes de Cervantes de los ya acumulados, incluyendo la posibilidad de que Sancho, junto con Rocinante, adquieran un papel de mayor protagonismo.
«Los animales de las Cantigas de Santa María. Una lectura en clave simbólica»
Authors: Fidalgo Francisco Elvira
Published: February 2021

En un buen número de cantigas de Santa María aparece mencionado algún animal. Su presencia puede justificarse por la necesidad de adornar la escena o por cuestiones de rima. Sin embargo, si al nombre de esos animales se le añade la simbología que portaban en la Edad Media, el texto de la cantiga cambia completamente, se enriquece y comprendemos mejor el mensaje que, con toda seguridad, era interpretado por el público medieval. En este trabajo se expondrán algunas muestras de cómo un texto que relata una anécdota se transforma en un verdadero exemplum al descodificar de manera correcta el significado simbólico que acompañan a ciertos animales en la Edad Media.
Enhancing Creativity in the Arts Field through Developing Students’ Innovative Capabilities
Authors: Mahgoub Yassir
Published: February 2021

This study aimed to enhance creativity in the field of arts through improving its participants’ innovative capabilities (i.e., the self-development of creative and critical thinking). The study was conducted on a sample of students and used descriptive analytics and an experimental approach. The students were required to approach the problem on three levels: the first level was to analyze the concept of innovative capabilities, the second level was to solve the problem of influences to enhance creativity, and the third level was the development of innovative capabilities. The results showed that there were statistically significant differences between the performance of the experimental and control groups before and after developing innovative capabilities, which confirms that the development of innovative capabilities led to enhanced creativity in students. In light of the results, the researcher recommends developing students' ability of independent thinking so that they can plan their tasks and develop creative strategies in the arts.
Biochemistry of fluoroprolines: the prospect of making fluorine a bioelement
Authors: Kubyshkin Vladimir , Davis Rebecca , Budisa Nediljko
Published: February 2021

Due to the heterocyclic structure and distinct conformational profile, proline is unique in the repertoire of the 20 amino acids coded into proteins. Here, we summarize the biochemical work on the replacement of proline with (4R)- and (4S)-fluoroproline as well as 4,4-difluoroproline in proteins done mainly in the last two decades. We first recapitulate the complex position and biochemical fate of proline in the biochemistry of a cell, discuss the physicochemical properties of fluoroprolines, and overview the attempts to use these amino acids as proline replacements in studies of protein production and folding. Fluorinated proline replacements are able to elevate the protein expression speed and yields and improve the thermodynamic and kinetic folding profiles of individual proteins. In this context, fluoroprolines can be viewed as useful tools in the biotechnological toolbox. As a prospect, we envision that proteome-wide proline-to-fluoroproline substitutions could be possible. We suggest a hypothetical scenario for the use of laboratory evolutionary methods with fluoroprolines as a suitable vehicle to introduce fluorine into living cells. This approach may enable creation of synthetic cells endowed with artificial biodiversity, containing fluorine as a bioelement.
BIOCHEMICAL COMPOSITION OF THE LIVER AND MUSCLES OF CYPRINID FISH
Authors: Guliyev Ruslan , Burlakov Ivan , Volkova Irina , Melyakina Elvira , Kryuchkov Viktor
Published: February 2021

Disorders in the liver are often accompanied by changes in its lipid composition. And since the liver performs many functions in the body, indicators of liver metabolic processes can reflect the living conditions and General condition of the fish body. The article provides information about some biochemical parameters of the liver and muscles of bream caught in the waters of the Volga Delta in different years. It seems that the causes of changes in the accumulation of lipids in the liver and muscles may be different factors (fish species, season, physiological state). Ultimately, the lipid content is determined by a number of processes. The complex of physiological and biochemical parameters proposed by the authors can be used to assess the degree of environmental stress on cyprinid fish.

Changing the Climate: Staff Development Activities that Address the Real Issues, Communication in the Workplace
Authors: Eads Denelle
Published: February 2021

When large libraries are fortunate enough to have multiple departments where staff are assigned to carry out specific tasks within their unit, broader communication lines within the entire organization are often disconnected. This, in turn, creates a one-dimensional level of communication that often hampers the ability to have a collaborative and engaged work environment within the organization. These environments often result in work relationships that are compartmentalized, providing very little interaction across organizational departments. Transforming the workplace environment to a healthier climate that involves employee engagement and cross departmental communication, can be accomplished through the efforts of a staff development committee. This article examines the effect that an organized staff development committee has on changing the climate in a workplace where the lack of communication among employees is a barrier to creativity and productivity and is often the source of low morale. In addition, this article will provide sample activities and programs that can be used to address communication issues that occur due to compartmentalized environments within workplace organizations.

Authors: GOCGUN Nurdan , İKİZCELİ Türkan
Published: February 2021

Objective: We aimed to present the relationship between ischemic stroke and COVID-19, stroke types, and imaging findings in COVID-19 with stroke.
Material Method: From March to November 2020, COVID-19 diagnosed in patients with stroke (n=10) was included in the study retrospectively. To eliminate intracranial hemorrhage, a non-contrast computed tomography (CT) was performed for all patients. Then, magnetic resonance imaging (MRI) and Diffusion-Weighted MRI (DWI) (n=10) were obtained. Magnetic resonance angiography was performed in patients whose CT angiography was contraindicated. Clinical information, stroke risk factors, and case imaging results were recorded. Stroke time, size, location (cortical, deep lacunar, and white matter), and vascular territory area were evaluated.
Results: The mean age of the 10 patients included in the study was 62±15.10 years. All patients had an ischemic stroke. In total, 4 cases (40%) did not have any risk factors for cerebral vascular disease. Based on DWI results, seven cases were assessed as acute strokes (70%) and three cases as sub-acute strokes (30%). The size of the stroke was 21.80±15.83mm. In 4 cases, the size was extended cortical areas. 3 cases were cortical, 5 cases had a lacunar infarction, 2 cases had cortical and lacunar infarctions. 6 cases were in the posterior cerebral artery territory and 4 cases were in the anterior territory.
Conclusion: The presentation of patients with stroke during COVID-19 therapy or after therapy might be considered the hypothesis that the virus led to a stroke, especially in cases accompanied by risk factors.
TECHNICAL EFFICIENCY OF VIETNAMESE MANUFACTURING FIRMS: DO FDI SPILLOVERS MATTER?

This paper investigates the spillover effect (backward, forward, and horizontal linkage) of foreign direct investment (FDI) firms on the technical efficiency of local firms. This research extends the literature by employing meta-frontier framework analysis which is superior to single stochastic analysis because each industry has a different combination of inputs (or dissimilar production technology). Using a large data set (178,700 firm-year observations), this paper finds evidence on the negative impact of the horizontal and forward linkages on the meta-technical inefficiency for the data set as a whole as well as in three economic regions, in private owned firms, and capital and labor-intensive sectors in Vietnam.

The multi-messenger discovery of gravitational waves (GWs) and light from the binary neutron star (NS) merger GW170817, associated with gamma-ray burst (GRB) 170817A and kilonova AT2017gfo, has marked the start of a new era in astrophysics. GW170817 has confirmed that binary NS mergers are progenitors of at least some short GRBs. The peculiar properties of the GRB 170817A radio afterglow, characterized by a delayed onset related to the off-axis geometry, have also demonstrated how some nearby short GRBs may not be identified as such with standard short-timescale electromagnetic follow-up observations. Building upon this new information, we performed late-time radio observations of a sample of four short GRBs with unknown redshift and no previously detected afterglow in the Swift/BAT sample in order to identify nearby (

Mpc) off-axis GRB candidates via their potential late-time radio signatures. We find a previously uncatalogued radio source within the error region of GRB 130626 with a

flux density consistent with an NS radio flare at a distance of ∼100 Mpc. An origin related to a persistent radio source unrelated to the GRB cannot be excluded nor confirmed given the high chance of false positives in error regions as large as those considered here, and the limited time baseline of our observations. Further radio (and X-ray) follow-up observations are needed to better understand the origin of this source.

We present the first spectroscopically resolved Hα emission map of the Large Magellanic Cloud’s (LMC) galactic wind. By combining new Wisconsin H-alpha Mapper observations (I
Hα
≳ 10 mR) with existing H i 21 cm emission observations, we (1) mapped the LMC’s nearside galactic wind over a local standard of rest (LSR) velocity range of +50 ≤ v
LSR ≤ +250 km s−1, (2) determined its morphology and extent, and (3) estimated its mass, outflow rate, and mass-loading factor. We observe Hα emission from this wind to typically 1° off the LMC’s H i disk. Kinematically, we find that the diffuse gas in the warm-ionized phase of this wind persists at both low (≲100 km s−1) and high (≳100 km s−1) velocities, relative to the LMC’s H i disk. Furthermore, we find that the high-velocity component spatially aligns with the most intense star-forming region, 30 Doradus. We, therefore, conclude that this high-velocity material traces an active outflow. We estimate the mass of the warm (T

e
≈ 104 K) ionized phase of the nearside LMC outflow to be

for the combined low and high-velocity components. Assuming an ionization fraction of 75% and that the wind is symmetrical about the LMC disk, we estimate that its total (neutral and ionized) mass is

, its mass-flow rate is

, and its mass-loading factor is η ≈ 4.54. Our average mass-loading factor results are roughly a factor of 2.5 larger than previous Hα imaging and UV absorption line studies, suggesting that those studies are missing nearly half the gas in the outflows.
Revisiting the Integrated Star Formation Law. II. Starbursts and the Combined Global Schmidt Law
Authors: Kennicutt Robert C. , De Los Reyes Mithi A. C.
Published: February 2021

We compile observations of molecular gas contents and infrared-based star formation rates (SFRs) for 112 circumnuclear star-forming regions, in order to reinvestigate the form of the disk-averaged Schmidt surface density star-formation law in starbursts. We then combine these results with total gas and SFR surface densities for 153 nearby nonstarbursting disk galaxies from de los Reyes & Kennicutt (2019), to investigate the properties of the combined star formation law, following Kennicutt (1998). We confirm that the combined Schmidt law can be fitted with a single power law with slope n = 1.5 ± 0.05 (including fitting method uncertainties), somewhat steeper than the value n = 1.4 ± 0.15 found by Kennicutt. Fitting separate power laws to the nonstarbursting and starburst galaxies, however, produces very different slopes (n = 1.34 ± 0.07 and 0.98 ± 0.07, respectively), with a pronounced offset in the zero-point (∼0.6 dex) of the starburst relation to higher SFR surface densities. This offset is seen even when a common conversion factor between CO intensity and molecular hydrogen surface density is applied, and it is confirmed when disk surface densities of interstellar dust are used as proxies for gas measurements. Tests for possible systematic biases in the starburst data fail to uncover any spurious sources for such a large offset. We tentatively conclude that the global Schmidt law in galaxies, at least as it is conventionally measured, is bimodal or possibly multimodal. Possible causes may include changes in the small-scale structure of the molecular interstellar medium or the stellar initial mass function. A single n ∼ 1.5 power law still remains as a credible approximation or “recipe” for analytical or numerical models of galaxy formation and evolution.
Unresolved Multiple Stars and Galactic Clusters’ Mass Estimates
Authors: Borodina Olga I. , Carraro Giovanni , Seleznev Anton F. , Danilov Vladimir M.
Published: February 2021

If not properly accounted for, unresolved binary stars can induce a bias in the photometric determination of star cluster masses inferred from star counts and the luminosity function. A correction factor close to 1.15 (for a binary fraction of 0.35) was found in Borodina et al., which needs to be applied to blind photometric mass estimates. This value for the correction factor was found to be smaller than literature values. In an attempt to lift this discrepancy, in this work the focus is on higher order multiple stars with the goal of investigating the effect of triple and quadruple systems adopting the same methodology and data set as in the quoted work. The result is that when triple and quadruple, together with binary, systems are properly accounted for, the actual cluster mass (computed as all stars were single) should be incremented by a factor of 1.18−1.27, depending on the cluster and when the binary fraction α is 0.35. Fitting formulae are provided to derive the increment factor for different binary star percentages.

Published: February 2021

Objective

To assess trends in incidence of cardiovascular disease (CVD) and mortality following incident CVD events in patients with rheumatoid arthritis (RA) onset in 1980–2009 vs non-RA subjects.

Methods

We studied Olmsted County, Minnesota residents with incident RA (aged > 18 yrs, 1987 American College of Rheumatology criteria met in 1980–2009) and non-RA subjects from the same source population with similar age, sex, and calendar year of index. All subjects were followed until death, migration, or December 31, 2016. Incident CVD events included myocardial infarction and stroke. Patients with CVD before RA incidence/index date were excluded. Cox models were used to compare incident CVD events by decade, adjusting for age, sex, and CVD risk factors.

Results

The study included 905 patients with RA and 904 non-RA subjects. Cumulative incidence of any CVD event was lower in patients with incident RA in the 2000s vs the 1980s. The HR for any incident CVD in the 2000s vs 1980s was 0.53 (95% CI 0.31–0.93). The strength of association attenuated after adjustment for anti-rheumatic medication use (HR 0.64, 95% CI 0.34–1.22). Patients with RA in the 2000s had no excess in CVD over non-RA subjects (HR 0.71, 95% CI 0.42–1.19). Risk of death after a CVD event was somewhat lower in patients with RA after the 1980s with an HR of 0.54 (95% CI 0.33–0.90) in the 1990s vs 1980s and 0.68 (95% CI 0.33–1.41) in the 2000s vs 1980s.

Conclusion

The incidence of major CVD events in RA has declined in recent decades. The gap in CVD occurrence between patients with RA and the general population is closing. Mortality after CVD events in RA may be improving.
