Finding the right price: supply chain contracts as a tool to guarantee sustainable economic viability of organic farms
Authors: Viganò Elena , Maccaroni Martina , Righi Selene
Published: January 2022

The aim of this study is to analyse the volatility of agricultural commodity prices and assess the effectiveness of supply chain contracts as possible tools to prevent it. The study refers to the cereal sector, which is of vital importance for the agri-food system of the Mediterranean area. Since Italy is the world’s largest producer of durum wheat semolina, the proper functioning of the Italian durum wheat supply chain is central to this investigation. The study was conducted following two different paths of analysis: (1) the calculation of volatility indices using annual and monthly data of durum wheat prices, both organic and industrial, observed in the Bologna Commodity Exchange (AGER); (2) the analysis of two organic durum wheat supply chain contracts, defined by a cooperative involving hundreds of Italian farms mainly from the Marche region and by an agricultural consortium operating in the Adriatic regions. Despite the limited number of cases examined, the present study shows how supply chain contracts can be valid tools for building stable relationships between the various players, from production to processing and distribution, guaranteeing farms fairer and more remunerative raw material purchase prices and higher quality standards.
The horizons of “the beautiful clarity”. Acmeism, the Petersburg school in the 1920–1930s.
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Chagin Alexey I.
Published: January 2022

The monograph is devoted to the destiny of an acmeistic line of development of Russian poetry in the 1920–1930s. It is shown in the work that acmeism which stopped its existence in 1914 already as an organized literary phenomenon, was preserved as a literary position, dissolved in a wide field of a post-symbolic poetry of a Petersburg school. Post-revolutionary creative activity by N. Gumilyov, A. Akhmatova, O. Mandelstam; the poetry by the representatives of the young generation of the 1920s K. Vaginov, A.Radlova, N. Tikhonov, I. Odoevtzeva are being examined in the work. Creative activity by the poets of Russia Abroad — V. Khodasevich, G.Ivanov, V. Smolensky, the poets of the “Paris note” — L. Chervinskaya, A.Shteiger — becomes to be an object of a steady analysis in the work.
“Why Do I Need a Heart, If There Is No One to Love...” Sentimental Correspondence of Tolstoy’s Teachers A.I. Osten-Saken and T.A. Ergolskaya
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Gladkova (Kalyuzhnaya) Lyudmila V.
Published: January 2022

The article is devoted to the study of Leo Tolstoy’s family archive and the establishment of the sources used by the writer when creating the novel “War and Peace”. A tribute to the sentimental tradition Tolstoy gave in his correspondence with T.A. Ergolskaya is pointed out. The sentimental correspondence of Tolstoy’s aunts A.I. Osten-Sacken and T.A. Ergolskaya is considered as a supposed source of correspondence between Princess Mary Bolkonskaya and Julie Karagina in the novel, and the family circle of reading in Yasnaya Polyana and its influence on Tolstoy is also studied.
Artistic Detail as an Element of Psychological Characteristics in the  and in the Novel “Anna Karenina” by Leo Tolstoy
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Kovaleva Galina N.
Published: January 2022

The article for the first time compares the techniques of depicting the inner world of the characters of the unfinished novel from the times of Peter I with the techniques of psychological characterization of the novel “Anna Karenina”. A comparative analysis of the elements of poetics of the two novels is undertaken in order to identify similarities or, conversely, to underline the differences between artistic means of historical novel and the novel “Anna Karenina”. Both works were created after Tolstoy had experienced a radical revision of the existing aesthetic views in the early 1870s, which led to the renewal of the system of artistic principles familiar to him. Based on the results of comparison, a conclusion is made about the thematic points of convergence between two novels, about the proximity of the elements of plot construction, the use of a single form of psychological analysis, the similarity of artistic techniques in describing psychological state of characters in the state of acute mental crisis. The undertaken research shows that in the novel devoted to Peter I and in the novel “Anna Karenina” Tolstoy recreated the mental perturbance of the characters, their thoughts, feelings, experiences reflected in their body language almost exclusively with the help of artistic detail, contrasting lexical pairs (“friend–foe”, “light–dark”, “clear–dim”), as well as a specific creative technique — semantic selection: repetition of one or two words, phrases, exclamations, that express psychological state of characters.
Character System in Leo Tolstoy’s Novel “Anna Karenina”: the Role of Secondary, Tertiary and Episodic Characters in the Creation of the Work’s Artistic Integrity
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Andreeva Valeria G.
Published: January 2022

The article examines the role of secondary and tertiary characters in the novel “Anna Karenina” by Leo Tolstoy in creating an artistic whole work, in illustrating the typicality and uniqueness of life situations, in revealing the depths of the human psyche. The study of a complex roll call of images, consideration of parallels between characters, analysis of the similarities of characters in the final text and versions, as well as some episodes that were not included in the novel, allows you to show the movement of the writer’s thought and his attitude to the characters, to understand the author’s system of values. As in his earlier works, in Anna Karenina, Tolstoy depicts the spiritual world of a person and illuminates in detail the inner struggle of the individual. But when creating Anna Karenina, the writer turned not to particular oppositions of heroes, but tried to create a hierarchy containing all human qualities and traits, basing it on the only possible divine idea that embraces everything. The author of the work compares the images and behavioral characteristics of the secondary characters in the final text and draft materials, noting several significant figures and situations not included by the writer in the novel.
L.N. Tolstoy’s Novel “Anna Karenina” in Russian Criticism: Typology of Positive Reviews (1875)
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Gorodilova Natalia I.
Published: January 2022

The article is devoted to the interpretation of the novel “Anna Karenina” in periodicals contemporary for the author. The appeal to critical articles of 1875, in which Tolstoy’s novel received a positive assessment, is motivated by the poor degree of their study. For the first time, materials from such publications as “Novosti”, “Remeslennaya Gazeta”, “Astrakhansky Spravochny Listok” and others are introduced into scientific circulation. The originality of the critical position of each reviewer is revealed, contradictions are noted in their judgments concerning the author’s intention, composition, system of images, narrative drawing. In the scientific tradition, there is a strong opinion that positive reviews are not of interest, since they contain only compliments to the writer without a serious analytical beginning. However, on one hand, among the reviewers who rated the novel positively, there was no consensus regarding the author’s intention. On the other hand, positive critical articles are a part of numerous judgments on the novel, expressed both in print on pages of periodicals and in personal documents (letters, diaries), therefore, they fit into the context of journal and newspaper polemics and are considered in the light of the reflection of typical judgments on the novel. In positive reviews, there are often direct or indirect references to the statements of critics who expressed a different point of view on the novel. The noticeable commonality of perception between ideological opponents convincingly proves that a positive reading of the novel did not yet testify to an understanding of the artistic idea of “Anna Karenina”.
Metaphysics in the “Code of Thoughts of Leo Tolstoy”
Authors:   State Museum of L.N. Tolstoy, Prokopchuk Yuri V.
Published: January 2022

The work is devoted to the study of the writer’s metaphysical views, which are reflected in the “Code of Thoughts of Leo Tolstoy”. The author deals with issues related to the history of the creation of the Code — a unique source, which was worked on by the Tolstovians V.G. Chertkov, F.A. Strakhov and others from the late 1880s to the early 1920s. It was supposed to reflect all aspects of Tolstoy’s worldview, including the main provisions of Tolstoy’s metaphysical concept: ideas about the divine principle, the soul, spiritual life, mind and consciousness, and the peculiarities of Tolstoy’s perception of the categories of material world. The author reconstructs Tolstoy’s metaphysics as it is presented in the Code, draws attention to the peculiarities of the compilers’ perception of certain issues of Tolstoy’s philosophy, and compares them with the interpretations of these issues available in the research literature. The article substantiates the relevance of studying and introducing into scientific circulation a source that gives a complete picture of Tolstoy’s personality, work and worldview.

Mente Digital vs Cultura Digital en la Educación Superior Colombiana
Authors: Afanador Cubillo Nicolás
Published: January 2022

La pandemia mundial vinculada a COVID-19 ha marcado el comienzo de una nueva normalidad en la que la tecnología digital y los enlaces de acceso remoto se han convertido en algo común, alterando la idea de lo presencial. Este estudio ofrece un análisis explicativo sobre los impactos de la cibercultura y la cultura digital en la intensión de uso de TI en la Educación Superior colombiana, con base en los hallazgos de una encuesta a nivel nacional realizada a principios de junio de 2020 con 376 respuestas.

Entre los hallazgos pertinentes, se descubrió que no existe un vínculo entre la exposición de los individuos a la cultura digital y su intención de utilizar los recursos técnicos, pero en el caso de la cibercultura ocurre lo contrario. Debido a que la cibercultura se define como hábitos y tradiciones vinculados con un sentimiento de colectividad, este hallazgo podría ser un primer indicador de por qué las organizaciones no adoptan una cultura digital efectiva.
Investigating new forms of content creation, storytelling and audience engagement to reveal the Genius Loci of heritage sites (The Workhouse, Southwell)
Authors: Andrea Moneta
Published: January 2022

Heritage Project at The Workhouse, Southwell, is a 5-year long collaboration partly funded by National Trust with Nottingham Trent University; it was enabled by National Trust’s Research Strategy aimed at ‘fulfilling the role of heritage in the modern world, realising experiences that move, teach and inspire’. The project was focused on The Workhouse, Southwell to reveal its Genius Loci (distinct character), to unearth its forgotten, denied and unexpressed stories; and to unveil them through Scenarchitecture, Moneta’s performative methodology that utilises architecture and performance to provoke visitors to think differently about history, identity and today’s world.
Scenarchitecture blends Imagination with Memory using a given architectural site; it works with the complex overlay of historical and contemporary fragments embedded in the host building, and it combines them with the stories, memories and meanings of the people that lived there. The aim of this process is to unveil feelings, to reveal invisible links between places and people, using perception and sensibility.
Moneta’s project was developed through research-led teaching: since 2015, a number of Theatre Design students had been involved as active researcher for content creation; they had been paired with Workhouse’s volunteers to engage with the building and its archive material; together, they devised different 'stories' inspired by The Workhouse’s archive; in the first two years of development the project inspired students’ installations; from 2017, after gaining interest from National Trust, the ‘stories’ evolved into a collective, costumed promenade performance open to public around The Workhouse, with the volunteers as storytellers and Moneta as project manager and director.
The project is now a regular and popular feature of The Workhouse’s Public Programme inspired by a specific year’s theme. Outputs included photos and video, website and blog, newspaper article, exhibition; in 2019, a documentary captured the development of the project and final performance.
Discovering the Altera Forma Urbis of Rome through a site-specific project and performance at Garbatella district, Rome
Authors: Andrea Moneta
Published: January 2022

The aim of the research enquiry was to uncover old and recent past history of Rome through a urban scenography design project that produced an exhibition (output 1: Segni Percorsi) and a sited performance (output 2: Tramandala), in the Garbatella district of Rome. Specifically, the research-led project was initially inspired by the ‘invisible’ structural urban form of Rome, the ‘Altera Forma Urbis’ in the shape of a ‘Star’. The aim was to explore connections with its contemporary structure focusing on the Garbatella district, area of study of the research. The final output (exhibition and a performance) was based on the findings of both historical and experiential analysis of the territory of the Garbatella district. The process in fact, revealed stories and characters that became the content of the storytelling of a site-specific performance for Teatri di Vetro 3, a site-specific theatre festival based in the courtyards of Garbatella’s building lots. Methods used to explore these enquiries involved recent studies by Italian archaeologist Giuseppe Lugli and his son Pier Maria Lugli (2006) on the ‘Altera Forma Urbis’ of Rome; the use of location-based digital technologies (Geo-Blog) for mapping, and Scenarchitecture, a trans-disciplinary methodology developed by Moneta (2012) for reading and interpreting the Genius Loci. The project involved 12 students of Module of Scenography of MA Architecture course at University of Rome La Sapienza, that exhibited their works at Urban Centre of Municipality XI of Rome, and then devised and performed during Festival Teatri di Vetro 3. Output 1 was funded in kind by Roma Europa-Palladium Foundation and output 2 by the Municipality XI of Rome. Feedback collected during the exhibition and after the performance evidenced the engagement of the audience with the ancient and recent past of Garbatella. The dissemination of the work includes two published articles.

Nitrogen addition mediates the effect of soil microbial diversity on microbial carbon use efficiency under long-term tillage practices
Authors: Zhang Mengni , Li Shengping , Wu Xueping , Zheng Fengjun , Song Xiaojun , Lu Jinjing , Liu Xiaotong , Wang Bisheng , Abdelrhman Ahmed , Degree Aurore
Published: January 2022

Tillage practices can influence soil microbial carbon use efficiency
(CUE), which is critical for carbon cycling in terrestrial ecosystems.
The effect of tillage practices could also be regulated by nitrogen (N)
addition. However, the soil microbial mechanism about N fertilizer
effect on microbial CUE under no-tillage is still unclear. We
investigated how N fertilizer regulates the effect of tillage management
on microbial CUE through changing microbial properties and further
assessed the impact of microbial CUE on particulate (POC) and
mineral-associated organic matter carbon (MAOC) using a 16-yr field
experiment with no-tillage (NT) and conventional tillage (CT), both of
which combined with 105 (N1), 180 (N2), and 210 kg N
ha (N3) N application. We found that microbial CUE
increased with increasing N application rate. NT increased microbial CUE
compared with CT under N1. The bacterial and fungal diversities of NT
was higher than CT and N application decreased their diversities in the
0-10 cm layer. The partial least squares path model showed that bacteria
diversity, fungal diversity, and fungal community structure played more
critical roles in increasing microbial CUE. Furthermore, POC and MAOC
under NT were higher than CT and they also increased with increasing N
application rate. This could be explained by the finding that increasing
microbial CUE induced by N application had the potential to increase POC
and MAOC. Overall, N addition is an important pathway to influence
microbial CUE, which is mainly regulated by bacterial and fungal
diversities rather than their biomass under no-tillage.

Density-habitat relationships of white-tailed deer (Odocoileus virginianus) in Finland
Authors: Poutanen Jenni , Fuller Angela , Pusenius Jyrki , Royle J , Wikström Mikael , Brommer Jon
Published: January 2022

In heterogeneous landscapes, habitat preference constitutes a crucial
link between landscape and population-level processes such as density
and sex ratios. We conducted a non-invasive genetic study of
white-tailed deer in southern Finland using fecal samples. We estimated
deer density as a function of landcover type using a Spatial
Capture-Recapture (SCR) model. Second-order habitat selection of
white-tailed deer revealed particularly high densities in fields and
mixed forest, and third-order selection was related to distance to
fields and transitional woodlands (clearcuts). Including landscape
heterogeneity improved model fit compared with assuming a homogenous
landscape. Our findings underline the importance of including habitat
covariates when estimating density.
Mid- and long-term outcomes of thoracic endovascular aortic repair in acute and subacute uncomplicated type B aortic dissection
Authors: Jubouri Matti , Al-Tawil Mohammed , Yip Ho Cheung Anthony , Bashir Ali , Tan Sven Zhen Cian Patrick , Bashir Mohamad , Anderson Richard , Bailey Damian , Nienaber Christoph , Coselli Joseph , Williams Ian
Published: January 2022

Background: Uncomplicated type B aortic dissection (un-TBAD) has been
managed conservatively with medical therapy in order to control the
heart rate and blood pressure to limit disease progression, in addition
to radiological follow-up. However, several trials and observational
studies have investigated the use of thoracic endovascular aortic repair
(TEVAR) in un-TBAD and suggested that TEVAR provides a survival benefit
over medical therapy. Outcomes of TEVAR have also been linked with the
timing of intervention. Aims: The scope of this review is to collate and
summarise all the evidence in the literature on the mid- and long-term
outcomes of TEVAR in un-TBAD, confirming its superiority. We also aimed
to investigate the relationship between timing of TEVAR intervention and
results. Methods: We carried out a comprehensive literature search on
multiple electronic databases including PubMed, Scopus and EMBASE in
order to collate and summarise all research evidence on the mid- and
long-term outcomes of TEVAR in un-TBAD, as well as its relationship with
intervention timing. Results: TEVAR has proven to be a safe and
effective tool in un-TBAD, offering superior mid- and long-term outcomes
including all-cause and aorta-related mortality, aortic-specific adverse
events, aortic remodelling, and need for reintervention. Additionally,
performing TEVAR during the subacute phase of dissection seems to yield
optimal results. Conclusion: The evidence demonstrating a survival
advantage in favour TEVAR over medical therapy in un-TBAD means that
with further research, particular trials and observational studies,
TEVAR could become the gold-standard treatment option for un-TBAD
patients.

Tetralogy of Fallot (TOF) is a common cyanotic congenital heart disease.
Its surgical correction requires ventricular septal defect (VSD) closure
and right ventricular outflow tract obstruction (RVOTO) relief, with
transannular patch enlargement (TAPE) of the pulmonary valve. The first
successful repair of TOF was reported in 1954 and consisted of closure
of the VSD through a large right ventriculotomy, and RVOTO relief with
TAPE of the pulmonary valve. To predict the intra-operative requirements
and post-operative course of patients with this condition, various
evaluation indices are available that can provide a good indication of
patient prognosis. In this case report, we describe a novel pulmonary
vein index (PVI) indicator that offers prognostic indications for
pediatric cardiac patients who have undergone surgical correction of
TOF.

On solvability of Riemann problems in Banach hardy classes
Authors: Bilalov B.T. , Sadigova S.R. , Alili V.G.
Published: January 2022

This work deals with the rearrangement invariant Banach function space X and
Banach Hardy classes generated by this space, which consist of analytic
functions inside and outside the unit circle. In these Hardy classes we
consider homogeneous and nonhomogeneous Riemann problems with piecewise
continuous coefficient. We define new characteristic of the space X related to
the power functions in X. Canonical solution is defined depending on the
jumps of the argument of the coefficient of the problem. In terms of the above
characteristic, we find a condition on the jumps of the argument depending
on the Boyd indices of space X, which is sufficient for the solvability of
these problems, and, in case of solvability, we construct a general
solution. We also give an orthogonality condition for the solvability of
nonhomogeneous problem. As X, considering specific spaces, we obtain
previously known results.

On the algebraic structure of polycyclic codes
Authors: Ou-Azzou Hassan , Najmeddine Mustapha
Published: January 2022

In this paper, we are interested in the study of the right polycyclic codes
as invariant subspaces of Fnq by a fixed operator TR. This approach has
helped in one hand to connect them to the ideals of the polynomials ring Fq [x]/?f)X)?, where f (x) is the minimal polynomial of TR. On the other
hand, it allows to prove that the dual of a right polycyclic code is
invariant by the adjoint operator of TR. Hence, when TR is normal we prove
that the dual code of a right polycyclic code is also a right polycyclic
code. However, when TR isn?t normal the dual code is equivalent to a right
polycyclic code. Finally, as in the cyclic case, the BCH-like and
Hartmann-Tzeng-like bounds for the right polycyclic codes on Hamming
distance are derived.

A new integral equality for the function whose higher order derivatives are
absolutely continuous are first improved by using the quadratic kernel
mapping with five sections. After that, refined inequalities of perturbed
Ostrowski type for bounded functions and mappings of bounded variation are
developed. What?s more, new effective composite quadrature rules are derived
to find closer estimates of the integral of a mapping. Some applications for
exponential and logarithmic functions are also obtained by using
inequalities presented in this study. Finally, new results involving
Cumulative Distribution, the reliability function and expectation value of
random variable are given.
Calmness of the solution mapping of parametric variational relation problems
Authors: Inoana Daniela

We consider a class of variational relation problems, depending on two
parameters from metric spaces. The issue under investigation is the

establishing some sufficient condition for calmness in a general framework, we
particularize the result for a variational inclusion and for an equilibrium
problem.
Accounting for Blood Donation: An Instructional Case
Authors: Burke Qing L. , Gujarathi Mahendra R.
Published: January 2022

Each year, millions of people donate blood at blood centers run by not-for-profit organizations such as the American Red Cross, which supply blood products to hospitals. Many people can also give blood plasma and receive cash compensation from for-profit pharmaceutical companies, which use plasma to develop and manufacture medical products. Blood donations raise interesting accounting issues. How should the blood and plasma donations be accounted for by a not-for-profit organization and a for-profit company, respectively? How are these similar transactions manifested differently in their financial statements? Is the accounting treatment consistent with the objectives of the entities? What are the ethical and social issues in paying for plasma donation? The case leverages students' familiarity with accounting standards for business enterprises to deepen their understanding of not-for-profit accounting. The case also challenges students to think critically about accounting concepts and improve their Codification research skills.
Political Connections and Accounting Conservatism
Authors: Baloria Vishal P.
Published: January 2022

Firms supply accounting conservatism in response to debt/equity contracting, litigation, political costs, and taxation demand from stakeholders. I examine whether political connections between U.S. firms and politicians moderate and/or intensify the impact of these demands on the supply of conditional and unconditional conservatism. I measure political connections based on the association between firms' campaign contributions and equity ownership in firms by U.S. House and Senate representatives. I measure conditional conservatism using an earnings-return model and unconditional conservatism using a persistent negative accruals proxy. I find that political connections moderate the effect of the debt contracting (litigation) demand for conditional (unconditional) conservatism. My results demonstrate whether and how political connections of U.S. firms can affect the four demands for and the supply of the two forms of conservatism. The collective evidence suggests that political connections serve as an alternative channel to reduce stakeholders' debt contracting and litigation demand for accounting conservatism.
Cross-Sectional Study Concerning the Knowledge, Attitude, and Practice of People With Diabetes Regarding the Prevention of Foot Ulcers in a Community
Authors: Awwad Khalaf Abdelfattah , Abu-khader Imad Rasheed
Published: January 2022

Foot ulceration is a serious problem among people with diabetes. This study assessed the knowledge, attitude, and practice of 483 people with diabetes with regard to the prevention of diabetic foot ulcers (DFUs). Data were collected using a valid and reliable questionnaire, and logistic regression was carried out to predict the effect of statistically significant independent variables on the scores of dependent variables. A significant association was found between knowledge and attitude about DFU prevention. Individuals who were unmarried were more likely to have higher knowledge scores than those who were married, and those who had university and secondary education were more likely to have higher attitude and practice scores than other groups. Overall, however, only a small percentage of study participants achieved high scores for knowledge, practice, and attitude in this study.

miRNAs are small noncoding RNAs that may contribute to common diseases through epigenetic regulation of gene expression. Little is known regarding the role of miRNAs in type 2 diabetes (T2D). We performed miRNA sequencing and transcriptomic profiling of peripheral monocytes from the longitudinal Multi-Ethnic Study of Atherosclerosis (MESA) (N = 1,154). We examined associations between miRNAs and prevalent impaired fasting glucose and T2D and evaluated the T2D-associated miRNA effect on incident T2D. Of 774 detected miRNAs, 6 (miR-22-3p, miR-33a-5p, miR-181c-5p, miR-92b-3p, miR-222–3p, and miR-944) were associated with prevalent T2D. For five of the six miRNAs (all but miR-222-3p), our findings suggest a dose-response relationship with impaired fasting glucose and T2D. Two of the six miRNAs were associated with incident T2D (miR-92b-3p: hazard ratio [HR] 1.64, P = 1.30E-03; miR-222-3p: HR 1.97, P = 9.10E-03) in the highest versus lowest tertile of expression. Most of the T2D-associated miRNAs were also associated with HDL cholesterol concentrations. The genes targeted by these miRNAs belong to key nodes of a cholesterol metabolism transcriptomic network. Higher levels of miRNA expression expected to increase intracellular cholesterol accumulation in monocytes are linked to an increase in T2D risk.

Background: Recent several reports have demonstrated that periodontitis is prevalent and adversely affects the survival in patients with chronic kidney disease (CKD) or end-stage kidney disease. However, its impact on transplant outcomes remains uncertain.Methods: This retrospective cohort study included 136 and 167 patients, respectively, who underwent living donor kidney transplantation (KT) at Seoul National University Hospital from July 2012 to August 2016 and Korea University Hospital from April 2008 to October 2018. We divided patients into three groups according to stages of periodontitis based on a new classification system. Results: Patients with severe periodontitis were older, had a higher prevalence of diabetes, a higher body mass index and C-reactive protein level, a lower cardiac output, and were more likely to be smokers, indicating its association with chronic systemic inflammation. After KT, stage IV periodontitis was independently associated with a lower incidence of acute T cell-mediated rejection, suggesting the possible effect of periodontitis on immune function. However, 1-year and 3-year estimated glomerular filtration rates were not different. Among the KT recipients followed up more than 3 years, new-onset cardiovascular disease occurred in nine patients, and coronary artery disease occurred more frequently in patients with stage IV periodontitis. However, diabetes was the independent predictor of new-onset coronary artery disease in multivariate logistic regression analysis.Conclusion: Our findings showed that periodontitis might be an important player in determining posttransplant outcomes in recipients. Further interventional trials to test whether treating periodontitis could modify transplant outcome are needed.

Published: January 2022

Objectives: The bicipital aponeurosis is a fascial expansion which arises from the distal tendon of biceps brachii muscle. It is an important structure for protecting the median nerve and brachial artery. The aim of this study was to analyze the morphometry and shape of the bicipital aponeurosis and its implications for the protection of the median nerve and brachial artery. Methods: Upper extremities of two fresh frozen and seven embalmed cadavers (five right, four left sides) were dissected. The ages of the cadavers varied between 60–86 years. The central length, superior width, central width, inferior width and the shape of bicipital aponeurosis were evaluated. All measurements were performed by using digital caliper. Results: The central length of the bicipital aponeurosis was measured 3.6±1.2 cm. The superior, central and inferior width of the bicipital aponeurosis were found 1.5±0.7 cm, 1.5±0.6 cm and 1.8±0.8 cm, respectively. Through the examination of upper extremities; two different shapes of bicipital aponeurosis were observed. In type I; the bicipital aponeurosis was fusiform in shape and observed in four upper extremities. In five extremities, it was found as quadrangular in shape and classified as type II. Conclusion: The morphometry and shape of bicipital aponeurosis have a clinical importance to protect the median nerve and brachial artery or to reduce compression of these neurovascular structures. A better understanding of bicipital aponeurosis morphometry is important in assessment of biomechanical properties of biceps brachii.

Objectives: Short leg casts are routine applications in orthopaedic practice. The aim of the study was to investigate the course of the common fibular nerve and its branches (deep and superficial fibular nerves) around the fibular neck in order to describe a convenient method for applying the lower extremity casts with low risk of fibular nerve entrapment. Methods: Fifty lower extremities of 26 cadavers were examined. The point where common fibular nerve itself or its branches (deep and superficial fibular nerves) crossed over the fibular neck were dissected. The points where the nerve or its branches have risk of compression between the fibula and the cast were investigated in relation to fibular length. Results: The average fibular length was 356.9±26.4 mm. The common fibular nerve did not pass over the fibular neck in any specimen, instead, its branches crossed over it. The average distance from the tip of the fibular head to deep fibular nerve and superficial fibular nerve were 42.9±6.5 mm and 52±6.3 mm, respectively. The mean ratio of fibular length to these distances were 8.5±1.2 and 7.0±0.8, respectively. Conclusion: As short knee casts is a frequent application in clinical practice, it is important to determine a safe upper border for the casts to protect common fibular nerve or its branches. We recommend that the upper border of short leg casts should not exceed the upper 1/7th of the fibular length of the patient in order to avoid fibular nerve palsy.

Published: January 2022

The anatomical variations of renal artery related with number, branching pattern and origin level have been well described. The variations regarding the course of the artery are limited and mainly related with its relation of vena cava inferior. However, diaphragmatic crus is also on the pathway of renal artery and this relationship might also have variations. Different from its usual precrural position, there are a few cadaveric dissections reported as retrocrural or transcrural renal artery. This is the report of a rare variant of renal artery course, where it was crossing between the fibers of diaphragmatic crus detected on CT angiography.

Mental health awareness is a condition when individuals are aware of the importance of mental health in maintaining their positive psychological well-being. Awareness involves prevention of mental problems, identifying mental problems, and self-managing in any possibilities of mental distuption. A way to maintain mental health awareness is to obtain knowledge or information related to disorders, management, and prevention of mental health problems through literacy. Meanwhile, Lack of mental health literacy have been identified as major obstacles for the promotion of mental health and early intervention during this pandemic era. This study aims to develop a measuring instrument by testing the validity and reliability of mental health awareness through literacy during the COVID-19 pandemic towards college students using the Rasch Model approach. The subjects of this study were male and female, college students aged 18 – 25 years and Indonesian citizens. This research was conducted on 307 subjects. The results of the research showed that the mental health awareness scale using Mental Health Literacy Questionnaire is a reliable and valid measuring instrument (α = 0.844) during the COVID-19 pandemic by using the Rasch Model approach and compared to the classical theory of mental health awareness. There are 21 valid items and 8removed items with no any dimensions are eliminated.

When entering college, first-year students faced new challenges. College adjustment is necessary in the early period of college because it can predict college success. Covid-19 pandemic hinders college adjustment due to distance learning. Meanwhile, a previous study conceptually mentioned that self-compassion supported college adjustment. This study examined the correlation between self-compassion and college adjustment among first-year college students in distance learning during Covid-19 pandemic. Undergraduate students batch 2020 (N = 381) were surveyed using Self-Compassion Scale and Student Adaptation to College Questionnaire. Pearson’s correlation test showed a positive significant correlation between self-compassion and college adjustment. The strongest correlation was found between isolation and personal-emotional adjustment. These findings indicated that self-compassion tends to help a better college adjustment in a distance learning context.
