On two-loop effective action of 2d sigma model
Authors: Akacevich P. V. , Ivanov A. V. 
Published: July 2023

AbstractIn this paper, we study two-loop contribution to the effective action of a two-dimensional non-linear sigma model. We derive a new formula, which can be applicable to a regularization of general type. As examples, we obtain known results for the dimensional regularization and investigate new types of a cutoff one. Also, we discuss non-local contributions and restrictions on the regularization.
Examination of gecko-inspired dry adhesives for heritage conservation as an example of iterative design and testing process for new adhesives
Authors: Olender Jacek , Young Christina 
Published: July 2023

AbstractRarely within the conservation of cultural heritage have conservation professionals been lucky enough to have materials custom-designed to meet their requirements. Most of the time the field must adapt solutions developed for other applications. The research presented here was initiated as part of a long-term aim to develop new adhesives for heritage conservation. Gecko-inspired dry adhesives (GDAs) are polymer tapes with micropatterns that are based on the adhesive properties of the pads of gecko lizard feet: they have strong normal and shear adhesion with low peel adhesion. They present potentially versatile and reversible adhesives for heritage conservation applications; which do not require solvents for activation or for removal, and do not migrate or off-gas. In nature, geckos can adhere with their feet to any surface they walk on. This is possible because of micro- and nanostructures on their feet that attach to surface via van der Waals forces. Practical studies aimed at comprehensively assessing their properties, and biomimetic solutions in heritage conservation are still sparse at present. This research has the objective of assessing GDAs properties by mechanical testing of adhesive joints, as well as physical and chemical characterisation of the materials used. The research has also included a museum case study and a two-year natural ageing test. The testing has shown that the GDAs can perform very well as an adhesive patch on the reverse of gelatine-based photographs, achieving shear forces between 0.80 N and 48.10 N on 8 cm2lap joints (depending on the type of the GDA) and peel forces between 0.20 N and 0.47 N over 2 cm of peel front. This is lower than forces exceeding 1 N recorded in widely available pressure-sensitive tapes. This shows that GDAs may have the potential of a sufficiently strong, yet easily removable adhesive that works well on materials widely present in museum collections.

Мета роботи: розпрацювання системного підходу в діагностиці рецидиву варикозної хвороби нижніх кінцівок після склерохірургічного та хірургічного лікування у віддаленому післяопераційному періоді.
Матеріали і методи. Проведено аналіз результатів обстеження і лікування 228 хворих на варикозну хворобу нижніх кінцівок, які проходили лікування в хірургічній клініці КНП “ЗОКЛ ім. А. Новака” ЗОР з 2012 до 2015 р. Критеріями включення в дослідження були хворі на варикозну хворобу (С2-С6 за CEAP). 1-шу групу хворих склали 153 хворі (оперовані 189 кінцівок), яким виконували склерохірургічне втручання. У 2-гу групу хворих увійшли 75 пацієнтів (96 кінцівок), яким виконувалось хірургічне лікування в основному флебектомія за Бебкоку – Нарату.
Результати досліджень та їх обговорення. При порівняльній оцінці результатів лікування хворих із варикозною хворобою нижніх кінцівок встановлено, що у 96 (100 %) хворих другої групи виявлено неспроможні пронизні вени гомілки, а в першій групі ці показники становили 183 (96,83 %) пацієнтів. Неспроможні пронизні вени стегна виявляли у 60 (31,75 %) хворих 1-ї групи та 30 (31,25 %) 2-ї групи.
Найчастіше ультразвуковою знахідкою в обстежених пацієнтів була неспроможність клапанного апарату пронизних вен у 96,83 % хворих 1-ї групи та 100 % випадків хворих 2-ї групи. Виявлення рецидуального стовбура магістральної ВПВ або його фрагментів є свідченням тактичних і/або технічних помилок допущених під час операційного лікування. Варикозна трансформація раніше інтактної МПВ та її притоків після представлених методів лікування є свідченням прогресуючого характеру перебігу захворювання. Аналіз дуплексного ангіосканування показав, що за 7 ультразвуковими критеріями порівняння статистично значимих відмінностей після склерохірургічного та хірургічного (венектомія) лікування варикозного розширення вен нижніх кінцівок не спостерігається.
Česká i-kmenová feminina na -n a jejich vývoj ve starší češtině (od r. 1300 do r. 1900)

Czech i-Stem Feminine Nouns Ending in -n and Their Development in Older Czech (from 1300 to 1900)
In this paper we follow both the functional and formal development of word-formative formants *-snь, *-znь, *-nь during the Old and Middle Czech periods and during the period of the National Revival and afterwards, and the word-formative and formal development of Czech i-stem feminines with the component -n- during the same period. These nouns are formed by derivation using the suffixes mentioned above or by conversion using the grammatical formant *-ь, and, after the disappearance of the softness correlation, they identically end in the form of direct singular cases on the -n nasal. In order to eliminate alternations of the morphological base, they change their ending in these forms from -(e)n to -(e)ň during their development. As a result, in the later developmental stages of the language, they converge formally to the Old Czech ja-stem feminines originally ending in -ně or -ně/-eň, which also changed their forms nom./acc. sg. in favour of the ending -eň during the development. At the same time, the no longer productive suffixes -n, -ně (in Proto-Slavic *-nьja) and partly also -sn, -zn (Modern Czech -seň, -zeň) merge into a new, self-applying suffix -(e)ň.

Czeskie rzeczowniki żeńskie z tematem -i zakończone na -n i ich rozwój w starszych okresach rozwoju języka czeskiego (1300–1900)
Niniejszy artykuł pokazuje zarówno funkcjonalny i formalny rozwój formantów słowotwórczych *-snь, *-znь, *-nь w okresie staro- i średnioczeskim oraz w okresie odrodzenia narodowego i poodrodzeniowym, jak również słowotwórczy i formalny rozwój czeskich rzeczowników żeńskich z tematem -i z komponentem -n- w tym czasie. Analizowane rzeczowniki są tworzone przez derywację za pomocą wymienionych sufiksów lub przez konwersję za pomocą formantu gramatycznego *-ь, a po zaniku miękkości w przypadkach niewymagających przyimka kończą się w liczbie pojedynczej spółgłoską nosową -n. W toku dalszego rozwoju, w celu wyeliminowania zmienności podstawy morfologicznej zmieniają swoje zakończenie w tych formach z -(e)n na -(e)ň. W rezultacie na późniejszych etapach rozwoju języka zbiegają się one formalnie ze staroczeskim tematem -ja rzeczowników żeńskich zakończonych pierwotnie na -ně lub -ně/-eň, które również zmieniły formy w mianowniku/bierniku liczby pojedynczej na końcówkę -eň. Jednocześnie nieproduktywne już sufiksy -n, -ně (prasłowiańskie *-nьja) i częściowo także -sn, -zn (współczesne czeskie -seň, -zeň) łączą się w nowy sufiks -(e)ň.
Surrealism, Socialist Realism, Dialogue?
Authors: Kozłowski Michał 
Published: July 2023

The text offers a critical and comprehensive review of Dorota Jarecka’s book Surrealizm, realizm, marksizm. Sztuka i lewica komunistyczna w Polsce w latach 1944–1948 [Surrealism, Realism, Marxism: Art and the Communist Left in Poland between 1944 and 1948]. The reviewer appreciates the main methodological premise of the book, namely that the tensions and conflicts generated within the triangle “avant-garde – realism – emancipatory role of art” cannot be reduced to a binary opposition between totalitarian ideology and the legitimate art world. In fact, it reflects the contradictory dynamics of politically engaged art in general and thecontext of post-war Poland in particular. Despite the book’s formidable factual support, the result of extensive and comprehensive query, the reviewer still regrets that the author remains primarily an art historian rather than social historian of art. This note of regret however does not diminish this noble contribution to understanding the logics of Polish visual arts in the aftermath of World War II. This area is much less known generally than the literature of this very period.

Published: July 2023

Contrast-induced nephropathy (CIN) is a prominent complication of ST-elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (pPCI). The systemic immune inflammation response index (SIIRI) is a novel inflammatory marker developed by multiplying the monocyte count by the systemic immune inflammation index (SII) and is associated with coronary artery disease severity. We investigated the predictive ability of SIIRI for detecting CIN in STEMI patients (n = 2289) following pPCI and developed a nomogram based on SIIRI for risk stratifying. CIN was diagnosed based on an elevation in baseline creatinine levels >.5 mg/dL or 25% within 72 h after pPCI; 219 CIN (+) and 2070 CIN (−) patients were included. CIN (+) patients had higher SIIRI than CIN (−) patients and SIIRI was an independent predictor of CIN. A nomogram based on SIIRI had good calibration and discrimination abilities for predicting CIN development. SIIRI was superior to SII in discriminating CIN (+) patients. Adding SIIRI to the baseline model, which consists of age, hypertension, hemoglobin, estimated glomerular filtration rate, albumin, ejection fraction, lesion length, and pain-to-balloon time, had a higher discriminative ability and benefit in detecting CIN (+) patients than baseline model as assessed by decision curve analysis.

Objective To evaluate the preliminary effectiveness of a goal-directed movement intervention using a movement sensor on physical activity of hospitalized patients. Design Prospective, pre-post study. Setting A university medical center. Participants Patients admitted to the pulmonology and nephrology/gastro-enterology wards. Intervention The movement intervention consisted of (1) self-monitoring of patients’ physical activity, (2) setting daily movement goals and (3) posters with exercises and walking routes. Physical activity was measured with a movement sensor (PAM AM400) which measures active minutes per day. Main measures Primary outcome was the mean difference in active minutes per day pre- and post-implementation. Secondary outcomes were length of stay, discharge destination, immobility-related complications, physical functioning, perceived difficulty to move, 30-day readmission, 30-day mortality and the adoption of the intervention. Results A total of 61 patients was included pre-implementation, and a total of 56 patients was included post-implementation. Pre-implementation, patients were active 38 ± 21 minutes (mean ± SD) per day, and post-implementation 50 ± 31 minutes per day (Δ12, P = 0.031). Perceived difficulty to move decreased from 3.4 to 1.7 (0–10) (Δ1.7, P = 0.008). No significant differences were found in other secondary outcomes. Conclusions The goal-directed movement intervention seems to increase physical activity levels during hospitalization. Therefore, this intervention might be useful for other hospitals to stimulate inpatient physical activity.

Objective The study aim was to investigate the prevalence of behavioral symptoms and burnout in healthcare workers in an intensive neurological rehabilitation unit in Messina, Italy, during the first COVID-19 lockdown in Italy. Methods Forty-seven healthcare workers (including neurologists, physiatrists, nurses and rehabilitation therapists) were enrolled in this cross-sectional study from February 2020 to June 2020. Participants were administered the following psychometric tests to investigate burnout and related symptoms: the Maslach Burnout Inventory, which measures emotional exhaustion, depersonalization and reduced personal accomplishment; the Zung Self-Rating Depression Scale (SDS); the Pre-Sleep Arousal Scale (PSAS); the Dyadic Adjustment Scale; and the Buss–Perry Aggression Questionnaire (BPAQ). Results We found several correlations between test scores and burnout subdimensions. Emotional exhaustion was correlated with SDS (r = 0.67), PSAS-Cognitive (r = 0.67) and PSAS-Somatic (r = 0.70) scores, and moderately correlated with all BPAQ dimensions (r = 0.42). Depersonalization was moderately correlated with SDS (r = 0.54), PSAS-Cognitive (r = 0.53) and PSAS-Somatic (r = 0.50) scores. Conclusion During the first COVID-19 lockdown in Italy, healthcare workers were more exposed to physical and mental exhaustion and burnout. Research evaluating organizational and system-level interventions to promote psychological well-being at work for healthcare workers are needed.

Published: July 2023

Background: Teriflunomide is a first-line oral immunomodulatory agent approved in China for the treatment of relapsing multiple sclerosis. Objective: To compare the treatment outcomes of teriflunomide and no disease-modifying therapy (DMT) treatment (in first year) in multi-center real-world Chinese multiple sclerosis patients. Design: Retrospective study. Methods: This study was conducted in five tertiary hospitals in different geographical regions of China. We collected clinical data of patients treated with teriflunomide and no DMT treatment (in first year) between 1 January 2017 and 31 August 2021. The effectiveness of teriflunomide was described. Potential factors influencing the effectiveness of teriflunomide were investigated. Results: A total of 372 patients treated with teriflunomide and 148 no DMT treatment patients were included. A total of 292 patients were treated with teriflunomide for at least 6 months, described as a stable teriflunomide cohort. The annualized relapse rate was significantly lower in the stable teriflunomide cohort than in the no DMT treatment cohort (0.23 ± 0.47 versus 0.87 ± 0.67, p < 0.001). The mean Expanded Disability Status Scale (EDSS) score of the stable teriflunomide cohort (1.77 ± 1.62) was slightly different from that of the no DMT treatment cohort (2.09 ± 2.00). A previous annualized relapse rate of ⩾1, a previous EDSS score of ⩾2, and a long disease duration of ⩾5 years were associated with better clinical effectiveness. Conclusion: Teriflunomide is associated with a lower relapse rate and less disability accumulation in Chinese patients with multiple sclerosis.

Published: July 2023

Objectives Numerous stress management interventions have been implemented in the workplace, but few are adapted to the healthcare setting. Due to the nature of their jobs, healthcare workers (HCWs) may find it difficult to adopt recommended stress management strategies. We present the protocol for a 12-week personalized stress management intervention among HCWs to change their behavior as well as improve physiological/psychological outcomes. Methods It is a pragmatic quasi-experimental study involving stressed HCWs from two general hospitals in Wuhan, China. The intervention group will receive a complex interactive multimodal intervention, including advanced education via mobile connection, participation in a web-based social network, tailored feedback, and the support of a nurse coach, while the control group will engage in self-guided stress management. Results The primary outcome is centered on behavioral measures, namely improvements in stress management practice frequency after a 12-week intervention. The secondary outcomes are the changes in stress-related physiological indices (i.e. high frequency variability and normalized unit assessed by Holter) and psychological indicators (scores on the Perceived Stress Scale and Depression, Anxiety, Stress Scale) following 12 weeks of treatment. Conclusion The knowledge translation intervention builds on a body of work defining the role of individualized instruction and feedback intervention, as well as group intervention through WeChat social network and personalized coaching. We believe this novel intervention will help HCWs promote their stress management awareness and skills, and ultimately benefit their long-term health.

Abstract
Background
Patients with a mental illness are more likely to develop, and die from, cardiovascular diseases (CVD), necessitating optimal CVD-risk (CVR)-assessment to enable early detection and treatment. Whereas psychiatrists use the metabolic syndrome (MetS)-concept to estimate CVR, GPs use absolute risk-models. Additionally, two PRIMROSE-models have been specifically designed for patients with severe mental illness. We aimed to assess the agreement in risk-outcomes between these CVR-methods.

Methods
To compare risk-outcomes across the various CVR-methods, we used somatic information of psychiatric outpatients from the PHAMOUS-, and MOPHAR-database, aged 40–70 years, free of past or current CVD and diabetes. We investigated: (1) the degree-of-agreement between categorical assessments (i.e. MetS-status vs. binary risk-categories); (2) non-parametric correlations between the number of MetS-criteria and absolute risks; and (3) strength-of-agreement between absolute risks.

Results
Seven thousand twenty-nine measurements of 3509 PHAMOUS-patients, and 748 measurements of 748 MOPHAR-patients, were included. There was systematic disagreement between the categorical CVR-assessments (all p < 0.036). Only MetS-status versus binary Framingham-assessment had a fair strength-of-agreement (κ = 0.23–0.28). The number of MetS-criteria and Framingham-scores, as well as MetS-criteria and PRIMROSE lipid-scores, showed a moderate-strong correlation (τ = 0.25–0.34). Finally, only the continuous PRIMROSE desk and lipid-outcomes showed moderate strength-of-agreement (ρ = 0.91).

Conclusions
The varying methods for CVR-assessment yield unequal risk predictions, and, consequently, carry the risk of significant disparities regarding treatment initiation in psychiatric patients. Considering the significantly increased health-risks in psychiatric patients, CVR-models should be recalibrated to the psychiatric population from adolescence onwards, and uniformly implemented by health care providers.

Trial registration
The MOPHAR research has been prospectively registered with the Netherlands Trial Register on 19th of November 2014 (NL4779).

Published: July 2023

AbstractBackgroundThe aim of the current study is to assess the surface roughness of several recent nickel-titanium (Ni-Ti) rotary endodontic instruments, namely: Protaper next (PTN); Hyflex CM (CM); Hyflex EDM (EDM); WaveOne gold (WOG); and trunatomy (TN), before and after application of 5.25% sodium hypochlorite (NaOCl) irrigant solution.MethodsIn this in vitro study, five recently introduced rotary endodontic instruments of different metallurgical properties and designs were subjected to Atomic Force Microscopy (AFM) analysis, and then each file was rotated in 5.25% NaOCl for 15 min., with speed and torque according to manufacturer’s instructions. The instruments were then subjected to AFM analysis again. The surface roughness average (Sa) parameter was calculated. Data were analyzed by Paired T test, One-way ANOVA and Tukey tests.ResultsThere was a statistically significant decrease in the surface roughness of all rotary endodontic instruments after immersion in irrigants (P ≤ 0.05).ConclusionThe new TN and PTN instruments showed the least surface roughness. All tested Ni-Ti rotary endodontic instruments after irrigants exposure showed a varying increase in surface roughness.
