Анотація. В останні роки все більше уваги приділяється плівчастим пшеницям, які вирізняються підвищеним вмістом поживних речовин у порівнянні з традиційними видами пшениці і є перспективною сировиною для розширення асортименту продукції здорового харчування. До таких пшениць відноситься спельта, три сорти якої нині вирощують в Україні. Післязбиральна обробка зерна, транспортування та зберігання у зерносховищах різного типу базуються на його фізико-механічних властивостях і їх врахування дозволить підприємствам зменшити втрати зерна під час обробки та зберегти його якість.
Стаття присвячена дослідженню фізико-механічних властивостей зерна плівчастої пшениці – спельти. Предметом досліджень було не обрушене (з квітковими плівками) та обрушене (зі знятими плівками) зерно спельти сорту «Зоря України» 2017 року врожаю. Залежно від вологості не обрушеної та обрушеної спельти визначено низку фізико-механічних властивостей зерна — натуру, масу та істинний об’єм 1000 зерен, кути природного укосу та коефіцієнти зовнішнього тертя у спокої (по сталі, гумі, пластмасі) і в русі. Встановлено закономірності зміни досліджених властивостей спельти від вологості зерна та запропоновано емпіричні рівняння, що описують ці зміни.
Результати проведених експериментальних досліджень показали, що натура не обрушеного зерна спельти залежно від вологості в межах 11,6…23,7 % складає відповідно 364…342 г/л, що практично у 2 рази менше, ніж обрушеного зерна, яке за вологості 12,3…23,5 % має натуру відповідно 706…644 г/л. З підвищенням вологості зерна натура та співвідношення між її значеннями для обох форм спельти зменшуються.
Маса 1000 зерен не обрушеного зерна спельти знаходиться у межах 41,5…57,5 г, а у обрушеного 102…117 г, тобто зростає у 2,5…2,0 рази відповідно до вказаних вище діапазонів зміни вологості не обрушеного та обрушеного зерна. Пропорційно у стільки ж разів змінюється істинний об’єм 1000 зерен обох форм спельти, який складає у тих же діапазонах вологості відповідно 102…117 см3 та 41,5…57,5 см3. Порівняльні відмінності досліджених властивостей спельти обумовлюються наявністю квіткових плівок у не обрушеного зерна.
Кут природного укосу спельти, який характеризує її сипкість, для не обрушеного зерна в межах дослідженої вологості дорівнює 29…40°, а для обрушеної спельти знаходиться на рівні 28…39°, що пояснюється різним станом поверхні квіткових плівок та обрушеного зерна спельти. У досліджених межах вологості визначені також коефіцієнти зовнішнього тертя спокою не обрушеної та обрушеної спельти по поверхнях різних матеріалів (сталь, гума, пластмаса), а також коефіцієнти зовнішнього тертя в русі.

Aim. Coronary artery calcification is a characteristic of coronary atherosclerosis, which is often detected by chest computed tomography (CT). The aim of this study is to assess the efficiency of low-dose chest CT in calcium score (CS) determining and to compare it with conventional method and results of CT and selective coronary angiography.Material and methods. A total of 251 patients underwent a low-dose chest CT and a CS determining. Coincidence between the two methods was evaluated by the absolute CS values and by stratification of patients into five risk categories (“zero” CS values were excluded from the analysis). Eighty patients underwent CT or selective coronary angiography and the results were divided into two groups according to the degree of coronary stenosis — ˂50% and ≥50%. The CS values determined by chest CT are compared with the results of coronary angiography. Results. In 79 patients (31%), the CS was 0 and they were excluded from further analysis. The absolute CS values comparability between the two scanning methods in other 172 patients was very high (r=0,978, p<0,05). The coincidence in stratification of patients by risk groups was also high (contingency coefficient k=0,846). The CS specificity compared with coronary angiography was 97,5%, but with a low sensitivity of 43,6%, if the CS value is set to 400, above which coronary stenosis will considered significant. In comparing CS values with results of CT, the relationship of high CS values with coronary stenosis, were statistically proved: in 17 patients from 18 with CS >400 significant coronary stenosis was detected, in comparison with 22 patients from 52 patients with a CS more than 400 (p<0,05). Conclusion. The research showed that low-dose chest CT can be used to determine CS. Studied values correlate with the results of coronary angiography.

Aim. To assess the role of global and selected scintigraphic scores of myocardial perfusion, blood flow and reserve in the anatomical and functional significance of coronary artery (CA) stenosis.Material and methods. The double-blind comparative study included 23 patients (mean age 61,2±6,8 years, 12 (52%) women, 11 (48%) men). All patients underwent stress dynamic single-photon emission computed tomography (SPECT) with adenosine triphosphate (ATP) (140 µg/kg/min in 6 minutes). Myocardial perfusion disorders were assessed by a semi-quantitative method, the total Summed Stress Score (SSS), the Summed Rest Score (SRS), and the Summed Difference Score (SDS) were determined. Global (g) and regional (r) myocardial perfusion (MP) were evaluated; myocardial perfusion reserve (MPR) was calculated as the ratio of MP at stress and at rest. Coronary angiography (CAG) was performed within 1 week after SPECT, the amount of CA narrowing was evaluated by diameter. Stenoses >50% were considered anatomically significant. The assessment of the fractional flow reserve (FFR) was performed by the ratio of the mean intracoronary pressure at the CA ostia to the pressure distal to the stenosis at the ATP infusion peak. FFR ≤0,80 was considered a sign of hemodynamically significant stenosis. Results. Neither regional nor global scintigraphic scores reflecting myocardial perfusion showed statistical significance as markers of CA stenosis >50%. Among perfusion markers, only SSSg (>4) showed good sensitivity and specificity in the diagnosis of hemodynamically significant (FFR ≤0,80) stenoses (AUC 0,76; p=0,002; sensitivity 81,8%, specificity 83,3%). The following regional flow scores allowed identification of hemodynamically significant CA: stress MPr ≤0,54 ml/min/g (AUC 0,8; p=0,0003; sensitivity 57%, specificity 92%) and MPR ≤1,5 (AUC 0,86; p< 0,0001; sensitivity 71,4%, specificity 92,8%).Conclusion. It is proved that global and regional scintigraphic scores of MP and MPR are sensitive and specific markers of hemodynamically significant (FFR ≤0,80) coronary stenosis. It can be more useful for localization diagnosis of the lesion than standard SPECT.

Aim. To modernize the computed tomography angiography (CTA) protocol with advanced data processing for the diagnosis of ascending aortic (AA) aneurysms, determining the aortic distensibility and compliance. Material and methods. We examined 24 patients (14 men) aged 43 to 72 years old with aneurysm or dilatation of ascending aorta (AA). CTA was performed on Siemens Somatom Definition AS and Philips Ingenuity Elite 128-slice scanners with electrocardiographic (ECG) synchronization after a bolus injection of contrast agents (100-120 ml). End-systolic and end-diastolic frames, maximum aortic diameter and cross-sectional area were determined; aortic distensibility and compliance were calculated.Results. According to AA diameter in end-diastolic frame, patients were divided into 3 groups. Group 1 — 6 patients, d< 45 mm (39 [39; 40] mm), group 2 — 7 patients, d =45-50 mm (48 [46; 49] mm) and group 3 — 11 patients, d >50 mm (51 [51; 54] mm). A correlation between aortic distensibility and compliance and such parameters as age, systolic blood pressure, systolic and was found. Correlation between the aortic compliance and diastolic diameter can be used for predicting of diameter increase rate.Conclusion. The designed CTA protocol with advanced data processing allows evaluating the AA distensibility and compliance by the diameter and cross-sectional area in patients with AA dilatation. These criteria provide additional information about the aortic elastic properties and can be used for determining the management strategy.

Aim. To develop and test a risk-stratification model for patients with coronary artery disease (CAD) and non-ischemic pathologies based on a computer analysis of electrical instability ECG markers.Material and methods. In the period from 2011 to 2018, the study included 1014 patients with CAD and non-ischemic pathologies. Depending on ventricular arrhythmia status, the analyzed cohort was divided into 3 groups: 1) 644 patients without lifethreatening ventricular tachyarrhythmias (-VTA), mean age 51,7±16,1 years; 2) 280 patients with clinically significant ventricular arrhythmias (+csVA): ventricular extrasystoles (VES) >1500/24 h, coupled VES >50/24 h or unstable ventricular tachycardia (uVT), mean age 46,7±14,0 years; 3) 90 patients with life-threatening ventricular tachyarrhythmias (+VTA): persistent VT (pVT), successful cardiopulmonary resuscitation (CPR), appropriate discharges by implanted cardioverter defibrillator (CVD), sudden cardiac death (SCD), mean age 46,8±12,7 years.Using the Intekard 7.3 software, ECG markers of myocardial electrical instability were analyzed: T wave alternation, QT interval and dispersion, fragmented QRS, spatial QRS-T angle, turbulence onset and slope, and heart rate deceleration/acceleration.Results. Statistically significant differences were found between the values of T wave alternation, QT interval, fragmented QRS and QRS-T angle in groups 1 and 3 (-VTA) and (+VTA), p<0,005.Personalized model was formed for predicting the risk of life-threatening VTA (primary endpoints: pVT, appropriate CVD discharges, CPR, SCD) in patients with CAD and non-ischemic pathologies (cardiomyopathy, channelopathy) in 5 years follow-up. Integral score of myocardial electrical instability is proposed as new quantitative parameter for risk stratification (sensitivity 75%, specificity 78%, accuracy 77%).Conclusion. The myocardial electrical instability score provides the individual assessment of the dynamic SCD risk. The Intekard 7.3 software is a simple, economic and accessible ECG tool for arrhythmia monitoring.

Aim. To assess the ultrasonography role for diagnosis of atherosclerotic lesions of the extracranial carotid arteries.Material and methods. The study was conducted on the basis of the St. Petersburg Mariinsky Hospital. A total of 855 patients who were admitted to the regional vascular center due to ischemic stroke or transient ischemic attack were examined. The mean age of the patients was 68 years (min 18, max 107). All patients underwent ultrasound of the carotid arteries.Results. In 570 (66,6%) patients with neurological symptoms (according to clinical and neurological examination), hemodynamically insignificant carotid artery lumen stenosis up to 70-75% was revealed. Ultrasound imaging in all patients revealed signs of atherosclerotic plaque (ASP) instability in various combinations, except for hemorrhage. It was not possible to clearly visualize the finished hemorrhage in the ASP structure.Conclusion. Despite the high informative value of ultrasound, it is not possible to answer all clinical questions with its single use. At the moment, there is no classification of instability signs, reflecting the ASP embolism risk. It needs for paternal change the management of asymptomatic patients. More detailed study of ASP destabilization using various visualization methods is necessary.

Aim. Comparative assessment of the economic results of rivaroxaban/acetylsalicylic acid (ASA) combination and ASA monotherapy use in patients with coronary artery disease (CAD) and/or peripheral artery disease (PAD). Material and methods. Based on the results of a large international multicenter, placebo-controlled, randomized clinical trial COMPASS, a model that evaluated the clinical outcomes of rivaroxaban/ASA combination and ASA monotherapy was formed. The economic results using cost and cost-effectiveness analyses, and budget impact analysis for two years were also calculated. The analysis took into account both direct medical costs (expenses for treatment, hospitalization due to complications, rehabilitation) financed under the compulsory health insurance, as well as indirect costs (loss of GDP due to disability or death). The calculation was made by accounting 100,000 patients with CAD and/or PAD.Results. Modeling of clinical outcomes per 100,000 patients based on COMPASS results showed a decrease of stroke prevalence by 649 cases, myocardial infarction — 301 cases, amputations — 478 cases, cardiovascular mortality — 476 cases when using rivaroxaban/ASA combination compared with ASA monotherapy. The cost-effectiveness analysis showed that rivaroxaban/ASA combination has greater clinical efficacy and lower costs in comparison with ASA monotherapy. Budget impact analysis showed that the switching of 100,000 patients with CAD and/or PAD from ASA monotherapy to rivaroxaban/ASA combination leads to budget savings of 1,026 million rubles in two years. This is due to a decrease in the incidence of cardiovascular events.Conclusion. It was found that the use of a rivaroxaban/ASA combination in comparison with ASA monotherapy in patients with CAD and/or PAD can both decrease a number of complications and lead to cost savings, despite the initially higher cost pharmacotherapy.

Aim. To study the effects of fixed-dose indapamide/perindopril combination on endothelial function and arterial stiffness in patients with uncontrolled stage 1-2 hypertension (HTN) and chronic kidney disease (CKD).Material and methods. Total of 100 patients with uncured or uncontrolled with ≥3 months antihypertensive therapy HTN and CKD G3 (67% females, mean age 59,1±12,5 years) were included in the study. Each patient took indapamide/perindop combination in accordance with 1 of 3 existing regimes (depending on doses) for 3 months. Primary aim was to assess the effects of indapamide/perindopril combination on endothelial function and parameters of arterial stiffness after 12 weeks of treatment (assessment by AngioScan diagnostic complex). Secondary aims were achievement of target blood pressure (BP) after 4 and 12 weeks of therapy and assessment of glomerular filtration rate (GFR) and the albumin-tocreatinine ratio (ACR) changes after 12 weeks.Results. Initially, there was an increase in arterial stiffness parameters in all patients, and during treatment decrease was observed: central systolic BP (SBP) from 120±10,1 to 112,9±6,3 mm Hg, median augmentation index from 10,9% to 4,6%, stiffness index from 8,1±2,4 to 7,1±0,9, vascular age decreased by 9,6% (р< 0,001 for trend). Significant improvement of endothelial function was observed regardless of diabetes presence: occlusion index increased from 1,5±0,3 to 1,7±0,5, median phase shift — from -4,6 to -2,4 ms (p< 0,01). After 4 weeks, 27% of patients reached target BP, by the end of the study — 90%. A decrease in the median ACR from 16,3 to 15,0 mg/g, GFR increase from 50,2±7,6 to 53,6±8,7 ml/min/1,73 m2 were observed (p< 0,01 for trend).Conclusion. Therapy with a fixed-dose indapamide/perindopril combination in patients with uncontrolled stage 1-2 HTN and G3 CKD leads to a significant improvement in arterial stiffness, endothelial and renal function, and achievement of target BP in 90% of patients.

Existing in Liminal Space: The Trajectory of a “Non-traditional” Anthropologist in a Clinical Research World
Authors: Vest Bonnie M. 
Published: January 2020

Abstract
Always interested in liminality, identity, and transitions, I reflect on how I came to embrace these tensions in my own academic career. In this paper, I discuss my experiences as a “liminal” anthropologist and illuminate the challenges and opportunities that arise from working between and across traditional disciplinary categories. I highlight lessons learned from “studying up,” focusing on identity negotiation and transition among National Guard soldiers during my doctoral work, to integrating qualitative, holistic perspectives into clinical and translational research in a medical school setting. Finally, I discuss implications for anthropological training and practice that highlight how we might better prepare students to translate anthropology to applied settings.

Abstract
Learning practical skills is key to becoming an applied anthropologist. For my MS degree, I chose a program at Boston University School of Medicine that incorporates skills development into the curriculum through its Service-Learning Internship Program (SLIP). The SLIP facilitates students' familiarity with their field site throughout the first year, before they start summer fieldwork. My SLIP and thesis fieldwork took place in a VA hospital's pain clinic—a placement ideal for my interest in researching pain management during an opioid epidemic. This paper describes my training, developing a research question, meeting theoretical and logistical requirements, handling the unpredictable nature of research, data collection, analysis, and writing. I use getting Institutional Review Board (IRB) approval for my thesis project as an example of how these skills came together. Guided by my mentors, this experience afforded me hands-on training. I can now bring my anthropological approach into the work force.

Abstract
How am I thinking anthropologically? This question was persistent and perplexing for me as I hammered out what it means to be an anthropologist working in public health. In this paper, I describe some challenges and opportunities that advanced my anthropological practice while working in public health settings. The lessons I gathered from my personal and professional journey formed the basis of a strategy I call “my cognitive anthropological toolkit.” I close this paper with suggestions for how a cognitive toolkit model can advance educational activities for present and future applied anthropologists.
