Authors: Lebedev D. I. , Evtushenko A. V. , Khorlampenko A. A.
Published: September 2021

Aim. To identify the factors influencing the development of postoperative atrial fibrillation (POAF).

Methods. The study included 100 patients with indications for cardiac surgery, aged 53 to 82 years (mean age 67.2±17 years). The group included patients who had no history of AF before surgery. Cardiac surgery in the group was presented in 63 patients by coronary artery bypass grafting, and in 37 – by intervention on the heart valves. All respondents were divided into 2 groups: the first included 39 people (39%) who had AF paroxysms lasting more than 30 seconds in the early postoperative period, with a peak at 1–2 days, in 13 (33.3%) cases of AF relapsed. The second group of patients was represented by 61 patients (61%) without cardiac arrhythmias after surgery.

Results. The dependence of the development of POAF on age, the concentration of C-reactive protein in the peripheral blood taken on the day of cardiac surgery, the longitudinal size of the left atrium before surgery was revealed.

Conclusion. It was found out that a number of factors such as age, preoperative left atrium size, C-reactive protein level in the first days after surgery suggest the development of POAF. The use of the predictors obtained can make it possible to develop an effective strategy for the prevention of POAF.

Published: September 2021

Aim. To cоmpare the results оf infra-spinal reconstructions of the lower extremities with the formatiоn of a distal anastomоsis below the knee joint fissure with the use of a bioprosthesis and autovein in critical limb ischemia (CLI).

Methods. The hospital results of revascularization were retrospectively analyzed in 53 patients with CLI who underwent primary prosthetics of the femoral-popliteal segment with the fоrmation of a distal anastomоsis belоw the knee joint gap. All patients, depending on the prоsthetic material used, were divided into two groups: 1) autovein was used as a prosthesis (39.6%, n = 21)) and 2) a bioprosthesis was used (“KemAngioprosthesis” closed joint-stock company “NeoCor” Kemerovo, Russia) (60.4%, n = 32).

Results. In the early postoperative period, thrombosis developed in group 1 in 7 cases (33.3%): in 5 patients – on the first day after the surgery; 2 out of 5 patients were with chronic arterial insufficiency (CAI) of the fourth degree, 1 was with acute arterial insufficiency of the first degree, and 2 patients with the third degree of CAI. In group 2, there were 6 prosthetic thrombosis (18.7%), 4 cases of which developed thrombosis on the first day, 3 patients with CAI of the fourth degree and 1 case with acute arterial insufficiency of the second degree.

Conclusion. The application of infra-lingual reconstructions using bioprostheses is quite effective and safe in patients with CLI, in particular with purulent-necrotic trophic processes when a suitable autovein to be used as a prosthetic material is absent.

Authors: Lyapin A. A. , Halivopulo I. K. , Tarasov R. S.
Published: September 2021

Aim. To evaluate the hospital results of one-stage radical correction (RC) of Fallot's tetrad (TF) and stage-by-stage correction of the defect using stenting of the right ventricular outflow tract (RVOT).

Methods. The group of step-by-step correction included 24 patients with the classic cyanotic form of TF: 1st stage – stenting of the RVOT (Me age 73.5 days, weight 3.8 kg), 2nd stage – RC of TF Me age 187 days. The group of one-stage RC TF included 30 newborns with Me aged 121.5 days and weight 5.5 kg.

Results. After performing stenting of RVOT, there was a significant increase in SpO2 from 80 to 94%, end diastolic volume of left ventricle index from 24 to 33.3 ml/m2 , a decrease in the severity of hypoplasia of the pulmonary artery trunk (PA) compared with the stage before stenting of RVOT (p˂ 0.05). Patients of the two groups had equal values of weight, SpO2, the severity of PA hypoplasia, and a gradient in the RVOT at the time of RC. After the RC in stenting group there was an increase in SpO2 up to 98%, a decrease in the RVOT gradient from 75 to 16.5 mm Hg, an increase in the end diastolic volume left ventricle index to 56.5 ml/m2 (p˂ 0.05). The dynamics of the status of patients in Group 1 with the use of palliative intervention did not significantly differ from the dynamics in Group 2 (one-stage RC TF).

Conclusion. Application of the approach of step-by-step correction of TF with stenting of RVOT in low weight infants with severe hypoxemia demonstrated an equal effect on the dynamics of SpO2, reverse cardiac remodeling compared with patients who underwent simultaneous RC of classical TF.

Published: September 2021

Aim. To evaluate the connection of calcium antagonist (amlodipine) therapy with the dynamics of the intima-media complex thickness in patients with arterial hypertension (AH), depending on genetic polymorphism.

Methods. The study included representatives of the indigenous nationality (the Shors) – 901 people, of which a group of 367 people with hypertension was identified. The prospective stage of observation included 234 people who did not receive antihypertensive therapy. Based on the prescription of calcium antagonists, patients with hypertension were divided into two groups. Gene polymorphism was tested by polymerase chain reaction.

Results. In the Shor cohort, the regression of the intima-media complex thickness of the carotid arteries was observed more often in hypertensive patients who received calcium antagonists if to compare them with those who did not take the drug [OR = 2.30]. In addition, the decrease in the atherosclerotic process is associated with the genotype carriage: I/I of the ACE gene [OR = 9.42], T/C of the AGT gene [OR = 3.52], 4b/4b and 4b/4a of the eNOS gene [OR = 2.26 and OR = 3.75], C/C of the MTHFR gene [OR = 2.62].

Conclusion. Pharmacogenetic aspects are valuable from the point of view of an individual approach and obtaining the most pronounced pharmacological response in order to slow down the processes of vascular wall remodeling in patients with hypertension.

Authors: Nishonov A. B. , Tarasov R. S.
Published: September 2021

Aim. To analyze the results of various revascularization techniques in high-risk non – STsegment elevation in acute coronary syndromes performed during the first 24 hours.

Methods. As a part of a single-center retrospective study, 45 cases of coronary artery bypass grafting (CABG) were examined in high-risk non – ST-segment elevation in acute coronary syndromes patients during the first 24 hours since their hospitalization for the period from 2017 to 2020. 45 cases of percutaneous coronary intervention (PCI) were selected from a similar group of patients with the help of the copy-pair method.

Results. The groups were comparable according to such significant factors as age, gender, postinfarction cardiosclerosis, diabetes mellitus, and multifocal atherosclerosis. However, the severity of coronary atherosclerosis according to the Syntax score was significantly higher in the CABG group (p = 0.0004). The groups were comparable in achieving complete revascularization (p = 0.2). In 8.9% (n = 4) of patients in the PCI group, unscheduled repeated revascularization was required, and in 15.6% (n = 7) of cases stent restenosis/thrombosis was detected during the hospital period and between PCI stages, while in the CABG group, congenital malformations and dysfunction were not found. Mortality in the groups did not differ significantly (4 (8.8%) versus 2 (4.4%), p = 0.4).

Conclusion. CABG provides freedom from repeated revascularizations, despite the initially more severe coronary lesion.

Authors: Onishchenko P. S. , Klyshnikov K. Yu. , Rezvova M. A. , Ovcharenko E. A.
Published: September 2021

Aim. To develop an algorithm for the automated functional design of the heart valve leaflet apparatus.

Methods. The geometry of the aortic valve leaflet was designed in the Matlab programming environment (MathWorks, Massachusetts, USA). Numerical modeling of the opening process was performed using Abaqus/CAE (Dassault Systemes, France).

Results. We developed an algorithm, with the help of which a set of models of the leaflet apparatus was designed. 8 models were subjected to numerical modeling of the stress-strain state. The locking pressure simulation has shown that the smallest von Mises stress value was recorded for a sample with a larger surface area of the leaflet belly and it equals 0.422 MPa. The results obtained show that the value of the radius of curvature significantly affects the behavior of the entire valve, which leads to the conclusion that it is necessary to carefully select the design of the valve apparatus for its correct functioning.

Conclusion. The study provides the primary confirmation that the concept of the algorithm is efficient for the automated functional design of the aortic heart valve leaflet apparatus.

Authors: Sedykh D. Yu. , Hryachkova O. N. , Kashtalap V. V. , Barbarash O. L.
Published: September 2021

Aim. To study the features of clinical and anamnestic characteristics and treatment of patients with hypertriglyceridemia (HTG) using the data of the lipid control center of Kemerovo.

Methods. The single-center retrospective study is based on the data of patients dynamic observation (n = 100) in the Dyslipidemia Registry of Kuzbass in 2019. A comparative analysis of clinical and anamnestic characteristics, lipidogram parameters and therapy was performed at the time when the patients were included in the study and after 6–12 months in patients with HTG (the criterion was the level of triglycerides (TG) above 1.69 mmol/L) and in patients without it. Indications for consulting a lipidologist were high cholesterol (levels of total cholesterol (TC) ˃7.5 mmol/L or low-density lipoprotein cholesterol ˃4.9 mmol/L or TG˃5 mmol/L), requirement of the high dose and/or combination therapy of lipid-lowering drugs; medical history of cardiovascular diseases and/or revascularization of vascular bed in patients under 55 years of age; suspected intolerance to lipid-lowering therapy due to the developed side effects; the issue of lipid-lowering therapy in complex clinical situations.

Results. Among the patients who visited a lipidologist in 2019, mixed hypertriglyceridemia was noted in 56 (56%) of cases, while 44 (44%) patients had other lipid metabolism disorders without increased levels of TG. A distinctive feature of patients with mixed hypertriglyceridemia is the lower incidence of myocardial infarctions (p = 0.029) and lower number of coronary stents (p = 0.018) in the medical history, despite the initially higher levels of TC (p = 0.005) and TG (p = 0.000). According to the results of 6–12 months observation, a significant decrease in TC (p = 0.001) and TG (p = 0.044) levels during the lipid-lowering therapy was revealed due to the addition of fenofibrate (p = 0.000) to all groups of patients who were monitored by a lipidologist.

Conclusion. The patients with dyslipidemia and HTG are a complex category of patients who require combined lipid-lowering therapy, which can only be prescribed by a lipidologist.

Published: September 2021

Aim. To analyze and scientifically substantiate the need for the creation of a program for the outpatient observation with COZANC using remote patronage.

Methods. The study prospectively included 150 patients with atherosclerosis of the arteries of the lower extremities. The average age of the patients was 68.3 ± 9.7 years. Clinical and anamnestic data were studied, and patients were interviewed using questionnaires and scales. Two observation groups were formed: the main one consisted of 70 patients, who were included in the program of remote patronage clinical examination, and 80 patients were under the standard model of outpatient observation with COZANC.

Results. For a 3-month period of outpatient observation, an audio communication session was carried out for 70 patients, once a month. During the reporting period, no acute cardiovascular events were recorded in the main group, while in the comparison group there were 3 (3.75%) myocardial infarctions. The development of CLI occurred in the main group in 1 case, while in the comparison group there were 4 (5%) patients, in one case the lower limb was amputated. In the comparison group, there were 3 ischemic events that resulted in a lethal outcome.

Conclusion. For the first time, a personalized remote patronage program was created and introduced into clinical practice at the level of primary health care, as a tool for optimizing the clinical examination program for patients with COZANC. The effectiveness of the remote patronage program for patients with atherosclerosis of the arteries of the lower extremities is described in relation to the prevention of acute cardiovascular events and the progression of COZANC.

Published: September 2021

Aim. To study “the portrait” of patients with acquired mitral valve (MV) heart disease of various origins and pulmonary hypertension hospitalized for surgical correction of the defect.

Methods. The study included 97 patients with acquired diseases of mitral valve and pulmonary hypertension. The assessment of demographic, clinical and anamnestic data, indicators of transthoracic echocardiography, quality of life before the correction of MV defect was carried out.

Results. The studied cohort is mostly represented by female patients (n = 70; 72.2%). The most common cause of mitral valve disease was rheumatic heart disease (n = 40; 41.2%). Overweight, hypertension (n = 76; 78.4%) and atrial fibrillation (n = 62; 63.9%) were the most common comorbidities. The mean pressure level in the pulmonary artery according to echocardiography was 35.5 (29.0; 40.0) mm Hg, with no significant difference among the patients, regardless the mitral defect etiology. Less pronounced remodeling of the left ventricle was noted in patients with rheumatic heart disease, which is caused by a lesion of the MV by the type of stenosis in contrast to patients with connective tissue dysplasia syndrome or against the background of detachment of MV chords with MV damage in the form of its insufficiency. There were no significant differences in the systolic function of the right ventricle depending on the etiology of MV defect.

Conclusion. The “portrait” of a patient with pulmonary hypertension associated with an acquired mitral valve defect before its correction is the predominance of female, overweight, with II or III functional class of chronic heart failure, more frequent rheumatic genesis of MV defect, the presence of concomitant pathology in the form of hypertension and persistent atrial fibrillation, and increased size of the left atrium and left ventricle, reduced systolic function of the right ventricle according to the data of Echocardiography.

Published: September 2021

Aim. To create a personalized cell-populated small-diameter vascular prosthesis in a pulsating bioreactor.

Methods. Tubular grafts were made by electrospinning from mixtures of biodegradable polymers, poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(εcaprolactone) (PCL). The inner surface is modified with fibrin. Tubular scaffolds were colonized with cultured colony-forming endothelial cells and grown under static conditions for 2 days. Then, the cell-populated prostheses continued to be cultivated for 5 days in a pulsating bioreactor system with a final shear stress of 2.85 dynes/cm².

Results. The advantages of the cultivation of cell-populated vascular prostheses in a pulsating bioreactor have been revealed. The selected mode of cultivation of cellpopulated vascular prostheses under conditions of a pulsating flow with a shear stress of 2.85 dynes/cm² did not have a damaging effect on the integrity of the endothelial monolayer. Moving unidirectional mechanical stimuli of chaotic orientation fibers of F-actin changed to a predominant orientation in the direction of flow, and also increased the expression of F-actin, Talin focal adhesion protein, and specific endothelial markers CD309, CD31, vWF.

Conclusion. The creation of a personalized cell-populated small-diameter vascular prosthesis with a functional endothelial monolayer is possible due to the use of autologous endothelial cells, autologous fibrin, and cultivation under conditions of a pulsating flow.

Conclusion. The 14-days program of early rehabilitation with aerobic training after surgical repair of valvular heart disease has demonstrated its safety and influenced the increase in exercise tolerance, peak oxygen consumption.
VOLUNTARY PENSION FUNDS IN CROATIA: INVESTMENT PERFORMANCE AND INCENTIVES
Authors:   University of Rijeka, Rijeka, Croatia Faculty of Economics and Business, Olgić Draženović Bojana
Published: September 2021

Saving for the third age is extremely important in the conditions of an uncertainty in the global economy, unfavorable demographic trends and the related problem of fiscal imbalances. In order to improve the sustainability of the Croatian three-pillar pension system, there have been recent attempts to significantly increase the role of voluntary pension insurance and other forms of saving for the third age. The aim of such measures is to reduce the increasing dependence of pension beneficiaries on payments from the state budget and to achieve a more sustainable pension system. Measures to encourage voluntary saving in Croatia are the state incentives for the insured and the tax benefits for employers. Despite the numerous investment advantages and government incentives for this form of saving, voluntary pension funds in Croatia are still among the least developed institutional investors, considering the amount of assets and the number of members. The question arises as to the reasons for the relative disregard of these financial institutions and the low interest of the working population in Croatia. The aim of this paper is to analyze the performance of voluntary pension funds and identify the reasons for the insufficient capitalised savings in the third pension pillar in Croatia. Keywords: Croatian pension system, voluntary pension funds, financial literacy, governement incentives
THE CHALLENGE FOR ECONOMICS FROM THE NEW “DIGITAL” ECONOMY: SHARING AND COLLABORATIVE ECONOMY THROUGH THE “PLATFORMS NEOCAPITALISM” OF THE 21ST CENTURY
Authors:   University of Valencia, Spain Faculty of Economics Department of Applied Economics, Hernandez-Carrion Jose Rodolfo
Published: September 2021

The so-called collaborative or sharing economy constitutes a multifaceted concept of increasing relevance and evolving in definition that will constitute the focus of our study. This article is presented methodologically as a macro-synthesis of the main trends of the economy, from its local and global spheres, in the convergence that can be glimpsed from the new phenomenon that we are dealing with of neo-capitalism based essentially on digital platforms and media. Some have already advanced it as turbo-capitalism or capitalism 3.0, in increasing expansion from the analysis of massive data from digital platforms. The resulting greater efficiency of decentralization and heterogeneity can be exploited by communities. We claim the need to support the constitution of public support that can constitute the response of the government to the multiple new challenges posed by what we are calling as “platform neocapitalism”, which dilutes countries in a planetary and accelerated scale, unimaginable at the beginning of the present 21st century. Keywords: sharing economy, digital platforms, collaborative economy

ENGLISH LANGUAGE AND ECONOMY IN THE DIGITAL WORLD
Authors:   University of Dubrovnik, Croatia Maritime Department, Vidak Nives , Golemac Zrinka
Published: September 2021

In the modern, globalised world English language has an important role as a means of communication. The use of language in business environment facilitates communication and economic efficiency. Global language survey, carried out in 2013 in 60 countries worldwide, links English language proficiency to economic and social development (ICEF Monitor, 2014). Results of the survey indicate that the countries with higher levels of English language proficiency have stronger economies and higher per capita income levels, and thus a better quality of life. Nevertheless, due to globalisation process and the Internet, the role of English has changed in so far as English proficiency is not only an economic advantage but also a basic skill needed for the entire workforce (ICEF Monitor, 2014). The aim of this paper is to give an insight into attitudes of students of economics and business economics on the significance of English in the business environment. The paper analyses differences in students’ attitudes in relation to the gender and the year of study. For that purpose, the research was carried out among the students enrolled in undergraduate study programmes at the Department of Economics and Business Economics. As the research instrument, the Questionnaire “English in Business Environment” has been applied. The research results indicate that the participants consider English language to be an important factor in economy and their future business environment. There were no statistically significant differences relating to gender while some statistically significant differences for the year of study have been found. This paper suggests further research based on a context-specific approach, to be carried out in other educational contexts, encompassing different study programmes and levels of study.

USTClitho2.0: Updated Unified Seismic Tomography Models for Continental China Lithosphere from Joint Inversion of Body-Wave Arrival Times and Surface-Wave Dispersion Data
Authors: Han Shoucheng , Zhang Haijiang , Xin Hailiang , Shen Weisen , Yao Huajian
Published: September 2021

Xin et al. (2019) presented 3D seismic velocity models (VP and VS) of crust and uppermost mantle of continental China using seismic body-wave travel-time tomography, which are referred to as Unified Seismic Tomography Models for Continental China Lithosphere 1.0 (USTClitho1.0). Compared with previous models of continental China, the VP and VS models of USTClitho1.0 have the highest spatial resolution of 0.5°–1.0° in the horizontal direction and are useful for better understanding the complex tectonics of continental China. Although USTClitho1.0 is implicitly constrained by surface-wave data by using the VS model from surface-wave tomography and the converted VP model as initial models for body-wave travel-time tomography, the predicted surface-wave dispersion curves from USTClitho1.0 do not fit the observed data well. Here, we present updated 3D VP and VS models of the continental China lithosphere (USTClitho2.0) by joint inversion of body-wave arrival times and surface-wave dispersion data. Compared with the previous joint inversion scheme of Zhang et al. (2014), similar to Fang et al. (2016), it is further improved by including the sensitivity of surface-wave dispersion data to VP in the new joint inversion system. As a result, the shallow VP structure is also better imaged. In addition, the new joint inversion scheme considers the large topography variations between the eastern and western parts of China. Thus, USTClitho2.0 better resolves the upper-crustal structure of the Tibetan plateau. Compared with USTClitho1.0, USTClitho2.0 fits both body-wave arrival times and surface-wave dispersion data. Thus, the new velocity models are more accurate and can serve as a better reference model for regional-scale tomography and geodynamic studies in continental China.

Authors: Kar Manoranjan , Singhal Somu , Mondal Bismoy , Roy Arijit
Published: September 2021

Background: Gastrointestinal anastomosis has been excited interest in our day to day surgical practice. We have compared efficacy, advantages, disadvantages, and complications following intestinal resection-anastomosis using extra-mucosal interrupted single layer suturing or continuous all layer suturing.Methods: This comparative study included 50 cases (either in emergency or elective undergoing bowel resection and anastomosis), comprising of 2 Groups (25 cases in each Group) between January 2019 to June 2021 at Midnapore Medical College and Hospital. Patients data, operative findings, duration of anastomosis and length of hospital stay, post-operative complications of all patients were followed till discharge.Results: Our comparative study have shown that- the mean duration for intestinal anastomosis in Group A (extra-mucosal interrupted single layer) and Group B (continuous all layers) were 21.43 minutes and 14.35 respectively. Considering duration of the anastomosis continuous all layers intestinal anastomosis appears to represent in shorter duration, anastomotic leak was noted in 3 patients (6%). Anastomotic leak was observed in 1 patient extra-mucosal interrupted single layer bowel anastomosis whereas two patients in the Group of continuous all layered bowel anastomosis had leak (p value 0.5-not significant) and the mean duration of hospital stay in the Group A and Group B were 7.32 days and 7.92 days respectively. (p value -insignificant).Conclusions: Duration required to perform a continuous all layer bowl anastomosis is lesser when compared to an extra-mucosal interrupted single layer intestinal anastomosis. There is no significant difference in complications, final outcome and duration of hospital stay between two Groups.

Authors: Tawab Abdul , George Madhu , Joseph Jino , Zacharias Ann Mary
Published: September 2021

Congenital protein C deficiency presenting as purpura fulminans is a rare condition in neonates. It is a disorder with autosomal recessive inheritance and is caused by homozygous or compound heterozygous mutations in PROC gene. The authors report a case of autosomal homozygous PROC gene transversion mutation in a newborn baby born to third degree consanguineous parents who presented as purpura fulminans at birth. She had almost undetectable protein C levels. As protein C concentrate was not readily available, she was managed with low molecular weight heparin along with fresh frozen plasma. Despite our best efforts, baby succumbed to her illness on day 21 of life.  Autosomal recessive protein C deficiency should always be sought as an explanation for thrombotic disorders in the newborn with manifestations of disseminated intravascular coagulation.

Сельскохозяйственные животные и птица не способны продуцировать эндогенную фитазу, такие минеральные вещества, как фосфор, кальций, а также белки и другие связанные с фитиновой кислотой питательные вещества, становятся менее доступны. В связи с этим, для более полного использования питательных веществ кормов, целесообразным является использование микробной фитазы. Согласно полученным данным по содержанию макро-, микроэлементов в костной ткани опытной птицы, отмечается, что как введение в корма цыплят-бройлеров минеральных веществ в виде премиксов, так и добавление в рацион фитазы в количестве 1 млн.ед. на тонну корма без минеральных добавок отмечается интенсификация образования костной ткани.

Химическая связь и «элементарные субстанции»
Authors: Утелбаева A.Б. , Жанабай Н. , Сулейменов Э.Н. , Утелбаев Б.T.
Published: September 2021

Согласно теории строения веществ, общепринятым положением является то, что связь между их составляющими частями осуществляется посредством химических элементов и элементарных частиц, состоящих из ядерно-электронных комбинаций, формирующих соответствующие молекулы или элементарные звенья макроскопического образования. Считается также известным фактом то, что в зависимости от природы химической связи вещества подразделяются на ионные, металлические, ковалентные, координационные и супрамолекулярные соединения. И в химических взаимодействиях при активации реагирующих веществ происходит разрыв и образование новых химических связей, где после завершения процесса количество нуклонов и электронов остаѐтся постоянным, и только изменяется структурноэнергетическое состояние системы. При этом происходит перераспределение элементарных структурных составляющих с образованием новых связей из исходных веществ, которое согласно структурно-энергетическому соответствию сопровождается с энергетическими проявлениями в виде тепла, света или других форм передач энергии. Однако в научных теориях при образовании связи предпочтение отдается взаимодействию валентных электронов с ядрами, а природа элементарных материй, осуществляющих энергетическую связь между электрон-электронными и ядерноэлектронными структурами, и их участие в химической связи не учитываются. В свою очередь кардинальные изменения индивидуальных свойств атомов и молекул при их химических превращениях означают то, что за изменение их структурноэнергетического состояния отвечают эти элементарные материи, названные «элементарными субстанциями». При стационарных условиях потенциальная энергия взаимодействия зарядов ядерно-электронных составляющих переходит в кинетическую энергию «элементарных субстанций» в виде пульсаций, и устанавливается энергетическое и электрическое равновесие характеризующееся электрической нейтральностью системы. И в настоящей статье рассматривается роль и физическая природа «элементарных субстанций», имеющихся в атомарной структуре веществ. Основываясь на ядерно-электронном строении веществ полагается, что, несмотря на всю сложность взаимодействия материй, их электрические свойства являются основой создания микро- макроскопических образований.

Literary Philosophy and the Use of Uselessness
Authors: Jarvie Scott A , Frattura Addyson
Published: September 2021

We build this work from the memory of the time we stumbled into tulips at city hall. As guard sirens fled off into the night, we wondered, “Maybe we can borrow some.” We ripped handfuls from the ground and ran. “Don’t worry,” we said, “they are too busy to catch us stealing tulips.” Likewise, we get away with this useless project because others are busy doing useful work: exigent, coherent, important work. We support much of that busyness, and at the same time wonder what is lost with all that attention towards usefulness. What we offer here, through a hybrid of reflective, poetic, essayistic and scholarly forms, may be an attempted escape from the obligations of scholarship. It may be indulgent. It may tell the reader nothing, or only what the reader already knows. Yet it is oriented towards an enduring promise. This is the promise of a literary experience, understood as a kind of resonance, ineffable primarily, but nevertheless one that matters. Such a promise is found in the power and possibility of story, through poetic lines that must be broken and conceptual tethers left incommensurable. We enter this space of breaking and unfurling through an inquiry into use.
 
The question of use and uselessness is one way of holding human contradictions in both hands. By this we mean that we make and leave space for literary and philosophical inquiries considered useless—in that they do not resolve anything—but nevertheless matterful. We suggest that readers meander these curated pages as they \ meander through an art exhibition or a museum. Within a literary exhibition one can wander through pages, spaces, and ideas. Pause. Dwell. Think. We curate a literary home beyond the demands of making something of use and we invite the reader to sit with us. As with an exhibition, possibility cannot be controlled for and so we exist in potentiality acknowledging both its positive and negative potential. Through our use, misuse, and abuse of literature and philosophy, we make ourselves a home in a possibility that can only be offered, not demanded. We manifest this literary home through fragments of philosophy evoked through a series of microfictions.
 
As scholars, learners, teachers, and writers we are often asked to defend what our writing does. And it is implicitly suggested that knowledge creation is the result. What is the use of a work that cannot promise new knowledge? Literary knowledge may only be one gorgeous possible ordering. It is a practice which produces a kind of knowledge which is no knowledge, which is useless.  If we must answer what it is that our writing does we suppose that—if anything—it offers up fictions for philosophizing. We explore a home for this work in scholarly contexts which too often find it useless, which is to say we position uselessness as a concept of value for our work as scholars, writers, and teachers. In the end we name no new uses but fiction; we steal tulips.
New Vox in Poetic Inquiry
Authors: Borhani Maya T.
Published: September 2021

As a doctoral candidate ever-deepening my understandings of arts-based research methods, in general, and performative and poetic methods of inquiry in particular, this paper advances several new theories of Vox in poetic inquiry (Prendergast, 2009, 2015, 2020), playing with the generative possibilities found with/in such poeticizing as writing method, performative gesture, and reflexive praxis, while addressing intersections between the personal/public and poetry as political currency. Woven as a métissage of poetic offerings within theoretical exposition, this essay links theory, research methods, and personal explorations with/in poetic inquiry. Found poems and original compositions punctuate the proposal of several new Vox to help elucidate our myriad voices within a growing chorus of poetic inquirers singing to a variety of purposes. A journey through methodological praxis unfolds, poses further questions, and encourages ongoing exploration and practice of poetic research methodologies in diverse, rhizomatically fruiting tendrils and directions.
“Institutionalized States of Information Abstinence”
Authors: Hare Kathleen (Kaye) A.
Published: September 2021

In this study, I provide applied examples of using cut-up poetic inquiry as an arts-based research method for analyzing erasure poetry. The erasure poetry was composed by five poet-participants and me during a sensory ethnography that explored embodied experiences of a sexual educator training program. I first overview erasure poetics in the context of sexuality education. I explain how erasure poetry as method can interrupt authoritative proclamations of truth, while also providing a technique to grapple with complex, corporeal data – central topics in sex education research. I then theorize cut-up poetic inquiry as an additional form of erasure, asking and illustrating how the processes of cut-up can distill information to enable emergent analytic insights in the context of my research. Throughout, I meditate on how erasure poetry as an arts- based research method can contribute to discussions of language, discourse, and embodiment in sex education research.
Thom Roberts Reads Crowns
Authors: Watfern Chloe
Published: September 2021

At Studio A, a supported studio for neurodiverse artists, the prolific painter, performer, photocopier, and installation artist Thom Roberts frequently reaches out to connect with friends and fellow artists by running his hands across the backs of their heads; “reading” their crowns. It’s a blessing I have been lucky enough to receive countless times over the course of my ethnographic engagement with Studio A, and as my relationship with Thom has developed. During my research, I have witnessed Thom read crowns in all kinds of contexts, from pubs to art galleries, in a performance artwork that could also be understood as an experimental artist talk. Here, I trace the narrative of this facet of Thom’s practice. I consider how such embodied encounters have the potential to open avenues of communication and connection between people who might experience the world in very different ways.
Re-touche
Authors: Vandecasteele Marieke , De Schauwer Elisabeth , Blockmans Inge , Van Hove Geert
Published: September 2021

Creativity and affect in families with a family member, who is labelled as disabled, is central in this article. These families are often pinned down to individual, closed categories where everything revolves around the label “disability.” Our research goes beyond binary thinking in terms of abled/disabled and other linear explanations by using artistic processes as ethnography. We start from encounters between two people who both created something about their “non-ordinary” brothers. One (first author) made a shortfilm/documentary about her own family, the other (research participant) wrote a TV series about a man who takes care of his brother after their mother’s death, which was not autobiographical yet inspired by his own experiences. The first author distilled etchings from their encounters, which piece together different layers: the scenarist’s biographical story, the story of creating the series, the series’ script and the first author’s thoughts and readings. The concept of re-touche—of touching and being touched, and in this way returning to family fissures and creating something new from them—runs through this art-based project.
How Can My Poem Be True?
Authors: Hoben John L.
Published: September 2021

How can a poem be true? This autoethnographic study uses poetic inquiry to explore the boundaries between fiction and reality within poetic experience. A series of poems composed during, and about, the current COVID-19 pandemic, provides a means of understanding the experience of having one’s everyday reality overturned by crisis. A central theme of the author’s poems and accompanying reflections is how art can be used to explore psychological experiences, such as melancholia and depression, and, in turn how the experience of suffering can be used to facilitate artistic expression. Using poetic inquiry, the author examines the complex interplay between speaker and authorial intention, fiction and truth, text and the performance of writing, reading, and poetic interpretation.
