Authors: Rafiei Ehsan , Safari Elnaz , Ghaffari Roshanak 
Published: April 2021

Introduction: Radiography is a valuable adjunct to the diagnosis of periodontal disease. This study aimed to compare the accuracy of two periapical radiographic and digital biting techniques in assessing bone resorption in posterior teeth of patients with chronic periodontitis.
Materials and Methods: This descriptive-analytical study was performed on 36 samples of interproximal surfaces of posterior teeth in patients with chronic periodontitis, candidate of flap surgery referring to the department of periodontitis, faculty of dentistry, Islamic Azad University of Isfahan (Khorasgan) in 2015. First two methods of imaging include periapical and digital bitewing were performed and the necessary distances were measured by a radiologist. Then, during surgery, and before the bone contour correction, the distance from the reference point to the alveolar bone shaft (gold standard) was measured by a Williams probe. Data were analyzed using Paired t-test. (α = 0.05).
Result: Out of 36 specimens, respectively in bitewing and periapical radiographs 2 and 1 cases were equal with clinical and in 16 (44.4%) and 20 (55.6%) distances were more. The average difference of amount of bone resorption in bitewing was 0.2 ± 0.12 mm and there was no significant difference between estimated mean value (p value = 0.01). Average difference of amount of bone resorption in periapical to clinical method was 0.87 ± 0.26 it was significant difference (p value = 0.001).
Conclusion: According to result, the use of bitewing radiography to determine the rate of bone resorption in posterior teeth is preferable to periapical radiography.

Case:
A 43-year-old man who underwent intramedullary nailing for a closed tibial fracture developed saphenous nerve entrapment neuropathy. He developed severe medial leg pain, which was worse on walking or standing, 2 years postoperatively. Surgical neurolysis resulted in complete pain relief and functional recovery of the limb without recurrence of symptoms.

Conclusion:
Clinicians should consider several etiologies in the diagnostic evaluation of a patient with chronic pain after limb trauma. If a patient complains of lower extremity pain after intramedullary fixation of closed fractures of the tibial shaft, the possibility of saphenous nerve entrapment neuropathy should be considered.

Published: April 2021

Introduction: COVID-19, a respiratory disease caused by the SARS-CoV-2 virus, was declared a pandemic by the World Health Organization (WHO) on March 11, 2020. It has affected millions of people and represents an unprecedented threat not only to health, but also to the economy and educational processes. In the confinement, one of the vulnerable groups is that of students of various academic degrees. The objective was to describe the manifestations of psychological discomfort and health derived from the confinement measures in students of a private university in the state of Guanajuato, Mexico. A secondary objective, due to the inclusion criteria, was to evaluate the differences between undergraduate and graduate students, as well as the associated factors in social coexistence, vulnerable groups and health measures.

Method: The participants were 641 students who were administered an online survey with a response rate of 77.6%. The participants were 63.1% women and 36.9% men. A total of 60.8% were undergraduate students and 39.2% graduate students. The mean age was 25.3 years. The instrument of measurement consists of 24 items, integrating Kessler's K-6 scale, with 6 specific questions on psychological distress referring to symptoms of anxiety and depression in the last month. Four questions on health aspects regarding COVID-19, 8 on healthy distance measures, and 6 on coexistence and habits at home were included. An odds ratio analysis was performed to identify the associated risk of health and coexistence with respect to psychological distress. At each stage, the ethical principles for the research were complied with and the dignity of the participants was respected, as well as the lawful treatment of personal information based on the principles of the current regulatory framework.

Results: The 92.6% lived in confinement with family, and the remainder alone or with friends. The 96.2% indicated not having symptoms of COVID. The 44.7% did not have a daily routine, 27.4% went out daily in confinement and 48.3% presented moderate to high and very high levels of psychological distress. A higher risk of presenting psychological distress was identified in women, postgraduate students, belonging to the health and humanities areas, presenting obesity and concern about being infected, not following sanitary measures and presenting any physical discomfort (ORs ranging from 2.05 to 7.02).

Discussion and conclusion: As in other populations, the monitoring of confinement measures is not uniform and there is a high proportion of psychological distress in undergraduate and graduate students. It is suggested to serve the population with higher risk with a comprehensive care model that incorporates the educational process, social coexistence and emotional management.

Published: April 2021

Objective: Gene expression profiling by microarrays or RT PCR had been studied in certain western centers to enhance the diagnostic accuracy of allograft biopsy, however, such sophisticated tests are difficult to apply in developing countries. This study was conducted to evaluate the expression of von Willebrand factor (VWF) and Interferon-gamma (IFNÎ³) as an end PCR product in renal allograft biopsy with different pathological categories.
Methods: Forty-nine indicated renal allograft biopsies were analyzed histologically by the Banff 2017 classification, inflammatory cell infiltration was analyzed by immunohistochemistry study for CD4, CD8, CD16, and CD68 markers, and a fresh tissue used for molecular study.
Results: The biopsy findings were acute T-cell mediated rejection (A- TCMR) 30.6%, interstitial fibrosis and tubular atrophy (IF/TA) 22.4%, C4d-Transplant glomerulopathy (TG) 12.2%, calcineurin inhibitor toxicity (CNI) 10.2%, C4d+antibody mediated rejection (AMR) 10.2% and normal histology 14.3%. The only significant difference in VWF expression was between acute TCMR and normal, P=0.01, Spearman's correlation also showed a significant relationship between VWF and acute TCMR (r=0.53, P=0.01), and VWF was found to correlate with the numbers of interstitial CD4+ (r=0.29, P=0.03) and CD68+ (r=0.37, P=0.007) cells. IFNÎ³ expression was significant in acute TCMR versus normal, P=0.009. Spearman's pair-wise testing showed that INFÎ³ correlated with CD8 in both the glomerular (r=0.38, P=0.006) and interstitial (r=0.30, P=0.04) compartments and with CD16+ interstitial cells (r=0.36, P=0.01).
Conclusion: our molecular and IHC data distinguish acute TCMR from other forms of transplant pathology and mildly dysfunctional kidneys with normal histology.

Published: April 2021

Abstract
This study empirically investigates the drivers of agricultural productivity in transforming economy. The study used a 35-year period (1980–2014) panel data sourced from World Development Indicators, Penn World Table, United States Department of Agriculture and Statistics on Public Expenditure for Economic Development. Data used for the study include Agricultural Productivity (AP), Real Gross Domestic Product (GDP), Government Agricultural Expenditure (EXP), Agricultural Trade Barrier (ATB), Consumer Price Index (CPI), Farm Machinery (MACH), Fertiliser (FERT), Human Capital (HCAP) and Irrigation (IRRG). Data were analysed using Impulse Response Function, Levin-Lin-Chu unit root test, Johansen-Fisher Panel Cointegration test and Panel Least Squares regression technique. Impulse Response Function revealed that ln (GDP)reacted negatively to a shock from ln (Agricultural Productivity). Levin-Lin-Chu unit root test revealed that the variables were stationary either at level or at first difference. The result of the Johansen-Fisher panel cointegration test showed that for every case at 5 percent level of significance, we reject null hypothesis of no cointegration. Panel Least Squares revealed that Agricultural Trade Barrier (α = 0.0531, p < 0.05), Human Capital (α = 1.2409, p < 0.01) and Irrigation (α = 0.0771, p < 0.01) increased Agricultural Productivity. However, Fertilizer (α = −0.0730, p < 0.01) decreased Agricultural Productivity. This study therefore concluded that Agricultural Productivity will grow in transforming economy with trade restriction on imported agricultural tradable commodities, increased investment in human capital and expansion in irrigation application. The study therefore recommends measures that will protect domestic agriculture, capacity building of the farmers and improved irrigation infrastructure that will enhance small scale farmers for all-season cropping.
Intervention Strategies in Foreign Exchange Market
Authors: Martin Vesna 
Published: April 2021

Abstract
The goal of the paper is to present the intervention strategies used by central banks in order to influence the value of the domestic currency, transparency versus discretion when it comes to publishing data about FX intervention and the cost and effectiveness of intervention. It is rarely that nowadays countries allow for an exchange rate to be formed on the market basis through the effects of supply and demand for foreign exchange on the foreign exchange market. The central bank buys or sells a foreign currency in the foreign exchange market in order to increase or decrease the value of its national currency in comparison to the foreign currency. The reasons for the intervention are the reduction of short-term oscillations of the exchange rate, the impact at the level of foreign exchange reserves, as well as the maintaining the price and financial stability as the ultimate goal of most central banks. The paper will present intervention strategies on foreign exchange market, which involves the implementation of interventions in the market of options, forward, foreign currency repo and foreign currency swaps. Then, on the spot market, interventions using an auction, as well as the application of foreign currency indexed certificates.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown etiology, presenting with variable clinical picture. Having a high heterogeneity and lacking pathognomonic features, very often the diagnosis poses a great challenge for the clinician. Several unusual clinical manifestations such as nasal septal perforation and digital gangrene can occur in LES patients.

Case report. We report the case of a 42-year-old woman, known with SLE, hospitalized in our department for a clinical presentation consisting of a recent major epistaxis, physical asthenia and acral necrosis of the upper limbs. Physical examination revealed an afebrile patient, with a cushingoid facies, facial telangiectasias, and necrotic scars localized on the distal phalanges, bilaterally.
A diagnostic nasal endoscopy showed a large septal perforation with the absence of the cartilaginous nasal septum. CT highlighted an extended defect at the level of the cartilaginous part of the nasal septum.

Conclusion. Nasal septal perforation remains an underdiagnosed invalidating complication of lupus and treated and discovered early could have an important impact on the general health of an already burdened by disease patient.
Prosthetic Heart Valves Thrombosis with Infectious Endocarditis - A Practical Review

Published: April 2021

Abstract
Simultaneous or sequential combination of prosthetic valve (PV) thrombosis and infectious endocarditis is a rare clinical finding. The management of these patients involves a complex multidisciplinary strategy using clinical judgment and imaging techniques. Transesophageal echocardiography (TEE) and especially 3D transesophageal echocardiography is essential. Moreover, positron emission tomography with fluorodeoxyglucose (F18-FDG PET/CT) can be a valuable tool to diagnose and manage these complicated clinical scenarios.
We present the case of a 65-year-old patient who was admitted in our clinic for paroxysmal nocturnal dyspnea and chills for one week. He had multiple surgical interventions for rheumatic mitral valve disease (percutaneous mitral valvuloplasty in 2008, and mitral valve replacement and tricuspid annuloplasty in October 2019).
At admission, the diagnosis of prosthetic valve thrombosis was established taking into account the clinical context (low INR values for the last two months), the patient symptoms and the echocardiographic findings. IV unfractionated heparin was administered. One week after admission the patient’s clinical status further deteriorated. TEE reevaluation showed partial thrombus regression with elements suggestive for concomitant infectious endocarditis. The diagnosis key is the clinical evolution and repeated TEE evaluations. In our case, they enabled the probable diagnosis of a sequential association of thrombosis and infectious endocarditis on mechanical PV. The therapeutic approach requires a high clinical suspicion and a prompt management, emergent surgery being the only lifesaving strategy in unstable patients with obstructive mechanical pathology.
Potential of End-User Electricity Peak Load Shift in Latvia

Published: April 2021

Abstract
One of the main challenges in the world as well as in Latvia is the reduction of the fossil fuel consumption. Electricity generation, which is still mainly produced by fossil fuel or nuclear power, is one of the largest shares. Nowadays end-users can efficiently control their electricity consumption by shifting electrical loads and taking into account fluctuating electricity price at Nord Pool. The smart metering systems have been expanding, but for the time being, end-users do not use this possibility efficiently.
This study provides an analysis of Latvian electricity consumption specifics and evaluates a potential to shift electricity peak loads. The study includes households, industry and commercial/public sector. Based on the questionnaire distributed among end-users, the initial data on equipment and usage profile were collected. The most essential equipment was reviewed to estimate the potential for load shift. The obtained results show that that there is a positive effect of the load shift. In the household sector, the average electrical load shift can be 6 % (95 GWh/ year) during a period at a cheaper price; in the industry sector on average 37 % (36.58 GWh/ year) and in the commercial/public sector there is no potential due to its specifics (working hours, constant use of refrigerators, etc.).
En rapport från danspedagogens perspektiv

Published: April 2021

Abstract
This article is about the first part of the artistic development research project called “Hoppsa Universum”. It was carried out in collaboration with the choreographer Anna Källblad 2006-2008. Ninety children from preprimary schools participated by taking part in dance- and movement sessions at the University College of Dance in Stockholm. After the sessions they were interviewed and the results were:

The children enjoyed dancing and thought it was fun and felt good about dancing

The children preferred running and other loco motor movements

The observations were videotaped and analyzed and the result gave new movements ideas as the children performed their own ideas without any instructions. The importance of exploration and improvisation within the class and within the learning process proved to be essential.
DANCEballad
Authors: Clausen Vicky 
Published: April 2021

Abstract
This article features the DANCEballad project which is in its seventh season of providing high quality dance for children and youngsters (aged 9-15) during their summer holiday.
Everyone with an interest in dance can join the project since no previous dance experience is required. The purpose of the project is to offer an opportunity for the participants to compose, perform and appreciate dance through their own uniqueness in cooperation with others. Another purpose of the project is to make dance become more visible throughout the regions by creating a base for development, continuity and interest for dance in the community in general.
The DANCEballad has been a great success with more than 600 student-dancers involved each summer.
Within only one week, the summer school dancers from each region have to create their own dance performance and present the choreography on a professional stage. The benefits for the participants from joining the project naturally vary from child to child. Previous evaluations show that personal and aesthetic development is part of the main benefits which e.g. become visible through enhanced self-confidence. In an aesthetic manner they broaden their horizons, interests and understandings of what dance can be and do. Through an interview with Sara Sejrskild, a DANCEballad participant, we get an example of what the summer dancers can achieve from the project.
Corridor – Käytävä Kulttuuriseen Mosaiikkiin
Authors: Turpeinen Isto 
Published: April 2021

Abstract
This article discusses a youth dance project called Corridor and its pedagogic and choreographic process. It introduces the author’s approach to coordinating and choreographing the project and argues for the benefits of working with youngsters cross-culturally.

Corridor took place at Kuopio Dance Festival in June 2009, bringing nearly 50 young dancers from six different countries onto the Music Centre stage. The title of the event, corridor, was turned into the theme of the concrete artistic work. It expresses a kind of space and mobility between people and ideas. Spectators, as well as choreographers and dancers opened doors to different cultures – here culture refers to the live, social environment which touches us, and in which the public and the private, the collective and the individual meet.
The author’s choreographic and pedagogical approach proceeds from a general to a detailed one. The work evolves in a spiral form starting from action which opens channels for relating to the present moment through dancing. Then this experienced action is shared and reflected on, either physically or verbally. The author aims at shared power and genuine dialogue. Similarly, instead of taking difference and complex dynamics as a threat, they are considered as resources and possibilities.

Corridor was a part of Keðja Kuopio a project which focused on children and young people. Furthermore, Keðja Kuopio belongs to Keðja project (Dance Encounters 2008 – 2010), the vastest platform so far aimed at dance artists as well as educators, producers and scholars to meet and address important issues within the contemporary dance field in the Nordic/Baltic region.
”To allow oneself to dance….”
Authors: Engelsrud Gunn 
Published: April 2021

Abstract
The purpose of the article is to illuminate the experiences of young dancers working with their own individual training in a context of contemporary dance education. Through a three-year programme, the students have kept logbooks and developed material based on the question: What were the essential experiences of individual training today? From having a focus on training strength, mobility, resilience, stamina and balance in the beginning, they often reoriented their training so as to give themselves the space to relate to and create confidence that their own subjective and relational experiences have validity in a professional dance context. As young, prospective professionals they learn gradually that what they experience is “not wrong”, but an expression of “where they are”. Their experiences contribute to the questioning of “narrow” definitions which a number of dance researchers also do today.
