Preliminary Effectiveness of a Remotely Monitored Blood Alcohol Concentration Device as Treatment Modality: Protocol for a Randomized Controlled Trial
Authors: Buono Frank D , Gleed Colette , Boldin Martin , Aviles Allison , Wheeler Natalie
Published: December 2021

Background

Alcohol use disorder is a chronic disorder with a high likelihood of relapse. The consistent monitoring of blood alcohol concentration through breathalyzers is critical to identifying relapse or misuse. Smartphone apps as a replacement of or in conjunction with breathalyzers have shown limited effectiveness. Yet, there has been little research that has effectively utilized wireless or Wi-Fi–enabled breathalyzers that can accurately, securely, and reliably measure blood alcohol concentration.

Objective

The purpose of this study is to evaluate the impact of a wireless blood alcohol concentration device in collaboration with long-term treatment on dropout rates, psychological distress, treatment motivation, quality of life, and need for higher levels of follow-up care for patients with alcohol use disorder.

Methods

The randomized clinical trial will include two arms, access to the wireless breathalyzer versus no access to the breathalyzer, while both groups have access to treatment. Evaluation will last 3 months with a 6-week follow-up, during which each participant will be interviewed at admission, 1 month in, 2 months in, 3 months in, and follow-up. Individuals will be recruited online through a secure telehealth meeting invitation. Outcomes will focus on the impact of the wireless breathalyzer within the alcohol use disorder population, and the combined effect on psychological distress, treatment motivation, and quality of life. In addition, we intend to investigate the impact of the breathalyzer on dropout rates and participants’ need for higher levels of follow-up care and treatment.

Results

The recruitment of this study started in July 2020 and will run until 2022.

Conclusions

This information will be important to develop cost-effective treatments for alcohol dependence. Ongoing monitoring allows treatment providers to take an individualized disease management approach and facilitates timely intervention by the treatment provider.

Kebijakan Omnibus Law dalam Perspektif Kebijakan Buruh di Indonesia
Authors: Hakim Yusril Rahman
Published: December 2021

Dalam penyelenggaraan pemerintahan di suatu negara diperlukan adanya aturan atau regulasi untuk mengatur masyarakatnya agar menjadi lebih teratur dan tertib. Regulasi atau aturan yang dimaksud adalah bagaimna kebijakan yang dibuat oleh pemerintah, baik itu undang-undang, PP dan sebagainya mampu menyelesaikan permasalahan yang ada di masyarakat. Dalam pengimplemntasiannya kebijakan publik melewati beberapa tahapan sebelum benar benar di realisasikan salah satunya tahap formulasi. Permasalahannya adalah ketika suatu kebijakan yang di formulasikan  masih pada tahap formulasi hanya berpihak pada beberapa oknum, tanpa melihat impact dari kebijakan itu yang berdampak pada masyarakat kecil seperti buruh atau pekerja contohnya Omnibus Law RUU Cipta Lapangan Kerja. Yang mana seharusnya kebijakan yang dibuat ditujukan untuk menyelesaikan masalah malah sebaliknya, hadirnya omnibuslaw malah menjadi momok buruk bagi para buruh dan pekerja lainya. Metode yang digunakan pada penulisan ini adalah metode literatur review dengan menggunakan analisis kebijakan Van Horn & Van Metter. Hasil serta temuan penelitian ini menemukan titik terang yaitu dimana omnibuslaw secara spesifik hanya menguntungkan pihak investor atau corporation dan melupakan pemenuhan hak hak terhadap buruh salah satunya penurunan UMK serta Pemutusan kerja tanpa tuntutan dsb.
Popular Uprisings in Sudan: Revolutionary Processes Intercepted
Authors: Musa Abdu Mukhtar
Published: December 2021

This article tries to go beyond the general features of the Sudanese three popular Uprisings of 1964, 1985 and 2018/19, to explore their root causes. It argues that the revolutionary processes in the Sudan have been impeded by such factors as: (1) lack of visionary leaders; (2) inter-elites dissensions; (3) intra-party schisms and inter-party conflicts (over interests); and (4) absence of coherent programmatic and mass political parties. Since independence in 1956, the Sudan has been trapped in a vicious circle—oscillating between democratic and military rules. So: “why does democracy fail in Sudan? It compares the different settings that differentiate the Uprising (of 2018/19) from the previous two, with especial emphasis on the latest one—one of the most successful non-violent civil resistances. The article explains that those uprisings could have escalated into full-fledged revolution but were let down by the civil elites who disappointed any prospects for revolutionary achievement”. Hence, the article rests on the hypothesis that “the political elite are responsible for the failure of the popular uprisings in Sudan”. The article provides empirical explanations for this hypothesis and suggests adoption of consociationalism which is more likely to suit the highly diversified Sudanese society with deep ethno-political polarization.

Experimental Study on Strength of Pervious Concrete by Using Fine Aggregate
Authors: Jawed Atif
Published: December 2021

Abstract: Pervious concrete is a special type of concrete, which consists of cement, coarse aggregates, water and if required and other cementations materials. As there are no fine aggregates used in the concrete matrix, the void content is more which allows the water to flow through its bodyThe main aim of this project was to improve the compressive strength characteristics of pervious concrete. But it can be noted that with increase in compressive strength the void ratio decreases. Hence, the improvement of strength should not affect the porosity property because it is the property which serves its purpose. In this investigation work the compressive strength of pervious concrete is increased by a maximum of 18.26% for 28 days when 8% fine aggregates were added to standard pervious concrete Keywords: W/C ratio, pervious Concrete, sugarcane bagasse’s ash, rice husk ash compressive strength, fine aggregates
UN ESTUDIO EXPLORATORIO SOBRE LA RELACIÓN ENTRE LA LEGITIMIDAD INSTITUCIONAL Y LA TRANSGRESIÓN NORMATIVA EN ARGENTINA
Authors: Beramendi Maite Regina , Zubieta Elena Mercedes
Published: December 2021

El presente trabajo busca conocer cómo un grupo de estudiantes universitarios caracteriza el sistema normativo en Argentina. Para tal fin, se analizaron las percepciones acerca de la transgresión normativa, la legitimidad del sistema y la vinculación de ambos aspectos. Los resultados muestran que los participantes desconfían del funcionamiento del sistema normativo, pues éste se maneja mediante prácticas corruptas, a través de instituciones ineficaces y con un sistema de dobles normas, piensan, a su vez, que el sistema está pensado para la conveniencia de los políticos y de los ciudadanos con poder. Básicamente, creen que el sistema es injusto e ilegítimo. Los estudiantes dan respuestas cínicas en relación a un posible cambio, piensan que la forma de conducirse en el sistema es mediante una moralidad individual, con un sistema propio de normas que contempla la transgresión y que, al mismo tiempo, procura no perjudicar a alguien en concreto.

EL PENSAMIENTO PRECIENTIFICO SOBRE LA SALUD Y LA ENFERMEDAD
Authors: García José E.
Published: December 2021

Los conceptos relacionados a la salud y la enfermedad están en el interés humano desde épocas muy antiguas en nuestro desarrollo como especie. Durante la prehistoria, las evidencias de trepanación indican concepciones tempranas de prácticas relacionadas a la salud. En las culturas antiguas, como los asirios, babilonios, egipcios y griegos, estos procesos se asociaron a creencias sobre infl uencias de entes espirituales externos y demonios sobre la mente y el cuerpo. Los griegos y romanos agregaron nuevos conceptos a la práctica médica, aunque varios de los antiguos preceptos subsistieron. El cambio en los marcos de referencia condujo finalmente hacia el más novel campo de la psicología de la salud. El principal objetivo de esta comunicación se concentra en repasar la evolución de las nociones de salud y enfermedad, a partir de sus variantes principales con énfasis en las antiguas formulaciones. El enfoque adoptado es descriptivo y se fundamenta en el estudio de fuentes primarias y secundarias, predominando estas últimas, en un intento por diferenciar las características propias de la etapa precientífi ca de la psicología de las concepciones actuales.

TIPOS PSICOLÓGICOS Y TRASTORNOS DEPRESIVOS
Authors: Amezaga Pilar , Saiz Mario
Published: December 2021

Este trabajo tiene como objetivo general investigar la tipología Junguiana, (Jung, 1921);  a partir de los resultados del Inventario Tipológico Forma G (MBTI, 1995) de Briggs-Myers, en una muestra de pacientes con Trastorno Depresivo, analizando a su vez, las relaciones con la Personalidad Depresiva y con los diferentes Patrones Clínicos de la Personalidad en una muestra de 82 pacientes con diagnóstico clínico de Trastorno Depresivo. Se estudia en primer lugar la relación entre el patrón tipológico y la depresión. En segundo lugar, la relación entre tipología y los diferentes patrones clínicos de personalidad, y en tercer lugar, comparamos la tipología en pacientes con y sin personalidad depresiva. Los resultados obtenidos muestran una clara preferencia por la Introversión sobre la Extroversión y de la Sensación sobre la Intuición en los Trastornos Depresivos (BDI-I, 1979) y en casi todos los Patrones Clínicos de la Personalidad (MCMI-III, 2007). A medida que aumenta la sintomatología depresiva se observa un mayor predominio de la introversión.

Legítima defesa, vingança privada e providência: as faces da justiça em Os irmãos Dagobé, de Guimarães Rosa
Authors: De Mello Sá Carvalho Ribeiro Gustavo
Published: December 2021

Dos principais temas presentes na obra de Guimarães Rosa, o da justiça foi elaborado de maneira muito peculiar e permanece atual ainda hoje. No espaço sertanejo da maioria das histórias escritas por ele, não há a presença do Estado e a justiça é realizada pelas próprias personagens ou pela providência divina. O cerne deste trabalho é verificar a construção de tal tema no conto "Os irmão Dagobé" de Primeiras estórias, livro de narrativas curtas publicado em 1962. Interessa averiguar também se o tratamento dessa matéria coaduna-se com o ambiente sócio-histórico representado na composição. Para tanto, partimos da análise de elementos narrativos, como a história, o narrador, as personagens e o espaço social, com base nos postulados de Genette em O discurso da narrativa para observar como essas categorias constroem o tema em pauta. Finalmente, conclui-se que a ausência do Estado no espaço rural de Minas Gerais, onde acontece a história, leva as personagens a fazer justiça pelas próprias mãos em busca de vingança em legítima defesa e que, nesse percurso, temos uma ação providencial que leva a paz ao espaço representado através da inversão da lei do mais forte. O embasamento teórico do trabalho, além da obra estruturalista já citada, consiste na crítica sobre nosso corpus como, por exemplo, Lugar do mito de Ana Paula Pacheco. Além disso, lançamos mão de teorias filosóficas e jurídicas da justiça, como Filosofia do direito, de Paulo Nader.

Published: December 2021

Realiza-se neste trabalho uma comparação das posições de Hannah Arendt e Gilles Deleuze em relação à importância da narratividade como meio para resistir e dar sentido à vida humana. Tanto Hannah Arendt quanto Gilles Deleuze sustentariam que o exercício da escrita é um meio para resistir ao totalitarismo e à banalidade do mal, nos termos da filósofa judia e alemã; ou uma maneira de clinicar em uma sociedade doente que procura asfixiar qualquer tipo de vitalismo individual, nas palavras de Gilles Deleuze.

Textual Criticism of Ostrovsky’s Translations from Latin. Part 1: Terence’s Hecyra and the French Intermediary Translation
Authors: Markov Alexander V.
Published: December 2021

Ostrovsky’s translations of the works of Plautus, Terence, and Seneca, preserved in incomplete drafts, attend to the textual criticism related both to the principles of the work and to its aims. The example of the translation of Terence’s Hecyra in comparison with the earlier translation of Plautus’ Asinaria proves the evolution of Ostrovsky’s translation principles. While Plautus was translated without recourse to an intermediary translation, Terence was translated from the popular bilingual edition, and the translator turned to a French translation in difficult cases. The article explains how Ostrovsky worked further with passages translated from the French or with reference to the French text, in which cases, on the contrary, he translated from the Latin without reference to the French translation, and this course of initial work determined the order of further editing of the rough translation. The self-editing went in the direction of both greater accuracy and expressiveness, which in the case of using an intermediary translation proved to be a clearly contradictory task. Reconstructing the history of the text in light of the identified source of the translation allows us to clarify a number of manuscript readings, to identify the pencil edits as belonging highly likely to Ostrovsky himself, contrary to the opinion of the first publisher of the translation, and to raise the issue of the stage intention of the translation.
Review of the Main Book Publications about Abkhazia by Russian Authors of the 19th Century
Authors: Avidzba Vasiliy Sh.
Published: December 2021

The article provides an analytical overview of the books by Russian authors of the 19th century, containing information about Abkhazia. Among the studied editions are well-known books that have widespread use in science, as well as rare ones, which have not been given due attention. The reviewed publications contain information about Abkhazia of a physical-geographical, military-topographic, military-statistical, historical-ethnographic, linguistic and archaeological nature. The article attempts to establish the differences in the authors’ cognitive interest in Abkhazia. The materials of the analyzed texts differ in terms of their volume, some of them represent a section or chapter of a book, and there are also generalizing publications entirely devoted to Abkhazia. Despite the discrepancies encountered between the editions in the description of the ethnic appearance of the Abkhaz people, they all contributed to the accumulation of knowledge about it, and played an important role in the formation of scientific Abkhaz studies. Biased assessments and condemnatory characteristics given by individual authors to historical circumstances have been critically analyzed.
“The Pugachevites” by E. A. Salias in the Reception of F. M. Dostoevsky: on the Epic Character of the Russian Novel
Authors: Mikhnovets Nadezhda G.
Published: December 2021

The article analyzes the nature of the interaction between first-line literature and fiction in the 1860–1870s as dynamic, versatile and dialogical. It is argued that the historical novel by E. A. Salias “The Pugachevites” (1874), based on the discoveries of the epic novel “War and Peace” by L. N. Tolstoy, testified to the process of strengthening the epic tendency in Russian literature of the 19th century. The novel by E. A. Salias was not exclusively secondary, the portrayal of the “predatory type” hero became innovative, but not deeply understood by the fiction writer. It is noted that further development was undertaken by F. M. Dostoevsky at the first stage of the creation of the novel “The Adolescent”. Its distinctive feature was the consideration of the “predatory type” in the context of the Russian history of spiritual quests of the 17th–19th centuries. The description of the stages of development of the type by F. M. Dostoevsky made it possible to come to the conclusion that the process of cognition of the Russian character, the identification of the laws of the historical development of Russia presupposed a versatile comprehension of the national foundations of life, which predetermined the epic character as the leading feature of the Russian novel of the second half of the 19th century.
The social disintegration from a mixed approach of quantitative and qualitative analysis
Authors: Gomes Mafalda , Martinho Ana Luisa
Published: December 2021

This paper aims to analyze, through a quantitative and qualitative approach, social categories related to vulnerability. This reflection is based on the analysis of concepts that are part of the sociology of poverty, exclusion, and social vulnerability, with contributions from the theory of intersectionality and the concept of social disintegration. Through this approach, vulnerability is a plural concept that results from the intersection of social positions, life experiences, and skills. In addition to the analysis of secondary data, the characteristics of social groups in situations of vulnerability will be examined through interviews with professionals who carry out their daily monitoring. The results indicate that social vulnerability results from the intersection of socio-demographic and economic factors that weaken the educational and professional trajectory of people in situations of vulnerability, particularly about their social and emotional competencies.

Authors: Colombi Cristiano , Kostyuk Olha , Mancini Flavio
Published: December 2021

The study extends a research already presented at the VII CIRIEC Conference and aims to elaborate, test and disseminate a scale for assessing the socio-economic impact of migrant female enterprises on their communities and their resilience capacity to the COVID-19 crisis. The research analyses four different areas: employment, economic growth and innovation, economic relations with the country of origin and local communities. The study consists of three different stages:1) Mapping of migrant female entrepreneurs (from Ukraine, Moldavia, Peru and Ecuador) in the City of Rome; 2) structured questionnaires; 3) in-depth interviews. Finally, a qualitative analysis is developed on a selection of 4 paradigmatic case studies. Thus, the research assesses the socio-economic impacts of migrant enterprises on the well-being of local communities and defines resilience strategies deployed by migrant enterprises in the fight against COVID-19, as well as the emerging needs of migrants’ enterprises induced by the crisis.

A RATIONAL SYNTHESIS OF MAGNETIC NANOPARTICLES INCORPORATED HORSERADISH PEROXIDASE NANOFLOWER AND ITS USE FOR THE REMOVAL OF PHENOL THROUGH OXIDATIVE COUPLING REACTION WITH GREAT REUSABILITY
Authors: ALTINKAYNAK Cevahir , ÖZDEMİR Nalan , ÖÇSOY İsmail
Published: December 2021

Herein, we report preparation of magnetic hybrid nanoflower (MhNF) formed of horseradish peroxidase (HRP), copper ions (Cu2+) and iron oxide nanoparticles (Fe3O4 NPs) with greatly enhanced activity, stability, reusability and applicability for use in removal of phenol from aqueous solution. In this study, pre-synthesized small sized Fe3O4 NPs were immobilized to synthesized HRP-Cu2+ hybrid nanoflower (hNFs). The synthesized MhNFs were characterized using SEM, EDX and XRD analysis. We also characterized the chemical structures of free HRP and MhNF using FTIR. The protein encapsulation yields of synthesized MhNFs were determined spectrophotometrically and calculated as ~98% for all synthesis conditions. The activities of free HRP, HRP-based non-magnetic hybrid nanoflower (hNF) and MhNF were calculated as 5847.6, 16738.2, and 18830.5 EU/mg, respectively. The optimum pH of the synthesized MhNFs for phenol removal was determined as pH 7. MhNF was easily and rapidly separated from reaction medium by an external magnetic field to be re-used. Even after seven cycles, MhNFs maintained more than 75% of their initial activity. We believe that the repeated use can reduce the capital and operation costs. The results are very promising in terms of increasing efficiency and applicability of HRP in industrial application especially for wastewater treatment.
A case report of an extremely rare type of cardiac tumor: Primary Cardiac Angiofibroma
Authors: Talebi Aisa , Davani Sam Zeraatian Nejad , Shahrbabaki Ali Saberi , Mesgarha Milad Gholizadeh , Mohammad Arash Pour , Zare-Mirzaie Ali
Published: December 2021

Cardiac angiofibroma is a very rare diagnosis when a patient develops an
intracardiac mass. It is a primary benign cardiac tumor with a scarcity
of information in the literature.  This case report illustrates a
26-year-old man with a complaint of chronic chest tightness who was
firstly diagnosed with right ventricle tumor by echocardiography then
underwent cardiac MRI which confirmed the presence of a highly-vascular
tumor with radiologically benign behavior. Then his tumor was excised,
his postoperative course was uncomplicated and he was well within almost
2 months after discharge. Ultimately the histopathologic findings
demonstrated vascular and stromal tissue in favor of angiofibroma and
excluded the other diagnoses with IHC and trichrome staining. 
Angiofibroma is a benign, highly vascular tumor, mostly discovered in
the nasopharynx. When it is found in the heart, CMR and pathology are
pivotal to rule in its diagnosis. It is isointense in T1 weighted and
hyperintense in T2 weighted sequences with intense enhancement following
contrast injection. Its pathology contains an admixture of vasculatures
with CD31 positive immunoreactivity for endothelial cells and fibrotic
tissue with bluish coloration in trichrome staining. Eventually, its
treatment includes merely surgical excision given its benign nature.
Photoconductivity on K-Feldspar
Authors: Uzorka Afam
Published: December 2021

In this paper the details of photoconductivity experiments on K crystal
are presented. Photoconductivity measurements were inconclusive as to
whether or not there was a current flowing during the 850 nm excitation
of a feldspar sample. However there was a clear current when exciting
the same sample with 515 nm light, but there was a complex relationship
between the magnitude of the current and the number of emission photons
counted. A model was developed to explain the photoconductivity results
where electrons migrate through the conduction band aided by thermal
excitation and tunneling.
Does dexmedetomidine reduce the risk of acute kidney injury after cardiac surgery: a meta-analysis of randomized controlled trials
Authors: Zhao Chunxiao , Liu Shuo , Zhang Huiquan , Gao Mengqi
Published: December 2021

OBJECTIVE: Acute kidney injury (AKI) is a common complication
after cardiac surgery, and there is no pharmacologic prophylaxis of AKI.
Some animal and clinical studies showed the renoprotection effect of
dexmedetomidine (DEX) on AKI, but data from other trials came to the
opposite conclusion following cardiac surgery. METHODS: We
searched databases including EMBASE, PubMed, and Cochrane CENTRAL for
randomized controlled trials (RCTs) focused on DEX for AKI in adult
patients after cardiac surgery. The primary outcome was incidence of
AKI. Secondary outcomes were mechanical ventilation (MV) duration,
intensive care unit (ICU) length of stay (LOS), hospital LOS and
mortality. RESULTS: Fifteen trials enrolling 2907 study
patients were collected in the meta-analyses. Compared with controls,
DEX reduced the incidence of postoperative AKI [odds ratio (OR), 0.66;
95%confidence interval (CI), 0.48-0.91; P=0.01], and there was no
significant difference between groups in postoperative mortality (OR,
0.63; 95%CI, 0.32-1.26; P=0.19), MV duration [weighted mean
difference(WMD), -0.44; 95%CI, -1.50-0.63; P=0.42], ICU LOS (WMD,
-1.19; 95%CI, -2.89-0.51; P=0.17) and hospital LOS (WMD, -0.31; 95%CI,
-0.76-0.15; P=0.19). CONCLUSIONS: Perioperative DEX use reduced
the incidence of postoperative AKI in adult patients undergoing cardiac
surgery. No significant decrease existed in mortality, MV duration, ICU
LOS and hospital LOS owing to the DEX administration.

reoperation, death within 24 hours postoperatively, and operative
mortality or missing data. 941 patients were included in the analysis
using the statistical software  SPSS, version 15.0.
Results 28.68% in the adult group and 20.07% in the pediatric
group developed CSA-AKI. Adult risk factors included age group of 60-69
years, cardiopulmonary bypass (CPB), number of grafts and hypertension.
In the pediatric group, CPB, aortic cross-clamping (ACX) and the lower
preoperative SCr are the main risk factors Conclusion
Conventional conservative management and preoperative Identification of
predictor risk factors are essential for prevention of CSA-AKI which
constitute the main strategy for optimal management.

Authors: Souka Athena , Maritsa Vasiliki Areti , Eleftheriades Makarios
Published: December 2021

Introduction: To compare the effect of a policy of screening for
spontaneous preterm delivery (SPD) by transvaginal cervical length (CL)
measurement versus a no screening policy in the prevention of severe
prematurity. Methods: Retrospective study on low risk singleton
pregnancies examined at 20-24 weeks. Two cohorts one with SPD screening
and the other without screening were matched using propensity analysis
to create the study groups. Women with short CL were treated with
vaginal progesterone and/or cervical cerclage/pessary. The outcomes
examined were SPD<32 weeks (SPD 32) and SPD between 20 and 32
weeks (SPD 20-32). Results: Screening for SPD was associated with a
significant reduction in the rate of SPD at less than 32 weeks (0.3% vs
0.8%, p=0.001 in the screened and no screened pregnancies respectively)
and in the rate of SPD 20-32 (0.3% vs 0.9%, p=0.005 in the screened
and no screened pregnancies respectively). After adjusting for maternal
age, parity, body mass index, smoking and mode of conception, the
screening group had significantly lower hazard for SPD 20-32 (HR=0.36,
95% CI: 0.18-0.75, p=0.006) and SPD32 (HR=0.39, 95% CI: 0.19-0.82,
p=0.013). Conclusion: Screening for SPD by transvaginal CL measurement
in mid pregnancy may reduce the incidence of severe prematurity in low
risk singleton pregnancies.
Wages, Work, and the Catholic Social Teaching
Authors: Hunnes John
Published: December 2021

The Catholic Social Teaching is a rich and relevant source for studying contemporary problems in society. In this paper, I investigate the question about equal pay in light of the social teaching. During the last decade, there has been an increasing interest in equal pay and related concepts like universal basic income. By equal pay we mean that everyone in society receives the same remuneration regardless of the type of work, level of effort, or unemployed or not. From an economic point of view, there are large negative incentive effects with such an arrangement. The reason is that the principle of ‘equal pay for all’ breaks the relationship between the workers’ effort and the payment associated with the effort. Furthermore, neo-classical economics would argue that there is no incentive to work if there is no financial payoff compared to not working. Also from a Catholic social teaching viewpoint, there is no support for an ‘equal pay for all’ arrangement. However, the social teaching sheds important light on the meaning of work and the right to a living wage.
The Foreign Direct Investment Job Multiplier During a Resource Boom: Evidence from Mongolia
Authors: Sayour Nagham , Schröder Marcel
Published: December 2021

This paper explores a particular job creation channel during a resource boom, using Mongolia as a case study. Resource booms can lead to impressive growth rates in resource-rich developing countries. The paper examines the link between resource booms triggered by new resource projects and FDI inflows into the non-resource sector on one hand, and FDI and job creation on the other. Its analysis focuses explicitly on the non-resource sector, where the positive economic effects of FDI are more pronounced than in the extractive sector.

Published: December 2021

Introduction. Anosmia and ageusia are one of the most common and characteristic symptoms of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection, with a frequency of almost 50% in patients in Western countries. Hypotheses proposing that the virus potentially affects the central nervous system (CNS) are on the rise. One hypothesis suggests that the virus enters via nasal mucosa and then enters the olfactory bulb via cribriform plate, with further dissemination to the CNS. Case report. A 34-year-old female patient experienced the loss of the sense of smell and taste about two months before testing positive for SARS-Cov-2. Coronavirus disease 2019 (COVID-19) presented with minor pneumonia and worsening anosmia and ageusia. After treatment, the patient recovered well, but anosmia and ageusia appeared again, varying in intensity, and since February 2021, they have become persistent. The case was evaluated by an otorhino-laryngologist, pulmonologist, and finally, a neurologist. In the meantime, the patient tested negative for SARS-Cov-2 and received two doses of the Sputnik V vaccine. Brain magnetic resonance imaging (MRI) was performed, and it clearly showed severe bilateral olfactory bulb atrophy. The patient has had anosmia and ageusia up to this day, and future MRI follow-up is planned. Conclusion. Loss of sense of smell and taste may be a predictor of further CNS dis-semination of the virus and possible neurological complications (which is still a subject of consideration). The olfactory bulb could be a gateway to COVID-19 intrusion into the CNS, and its atrophy could be an indicator of the process. Further investigation on this topic is required, including a wide application of MRI, in order to come to definite conclusions.
The impact of late liver allograft dysfunction on physical activity of liver transplant recipients

Introduction. Liver transplantation restores patients' physical and social life, and its quality. The prevalence of low physical activity in liver recipients is unknown as well as the impact of late liver allograft dysfunction on it. Liver transplantation enhances patient's return to the usual physical and social activity and improves the quality of life. However, the prevalence of low physical activity among liver recipients and the impact of the late allograft dysfunction on it, which is a risk factor for obesity and cardiovascular diseases, require studying.

The aim of the study was to identify whether the late liver allograft dysfunction influences the physical activity of recipients.

Material and methods. The study included 87 liver recipients. We measured anthropometric parameters, physical performance (SPPB, LFI, 6-min walk test), mean step count per day. Late liver allograft dysfunction was determined if elevated transaminases and/or cholestatic enzymes or hepatic failure have been diagnosed later than 3 months posttransplant. Activity trackers were provided to assess physical activity.

Results. Median age was 54 years [45;61], 33% were men. The median follow-up period was 36 months [16;64]. The median of the average steps count was 5.9 [4.1;8.7] thousand per day. 60.5% of recipients were sedentary and low active, 24.4% were somewhat active, 15.1% were active. In cases of liver allograft dysfunction, the mean step count was significantly lower than in patients with normal liver function: 4.1 thousand [2.6;5.3] versus 6.8 thousand [4.2;9.4], p=0.003, despite no differences in the physical activity test results.

Conclusion. In case of a late liver allograft dysfunction, the physical activity can decrease; 60.5% of liver recipients, in the absence of pathological restriction of movement, have a sedentary and low active lifestyle. Activity trackers may allow identifying patients who need additional check-up or physical training.

Introduction. Liver transplantation is considered the most effective treatment for patients with end-stage liver disease. X-ray endovascular interventions show good results in the treatment of vascular complications after transplantation. The timing, indications and choice of treatment methods require clarification.

Objective. To evaluate the safety and efficacy of emergency X-ray endovascular interventions for arterial complications in the early period after liver transplantation.

Material and methods. In the period from October 2016 by July 2021, 88 liver transplants were performed. The graft was obtained from a posthumous donor in 75 cases, and from a living donor (right lobe of the liver) in 13 cases. Arterial complications were registered in 10 cases: thrombosis of the hepatic artery in 7 (8.0%), constriction in 3 (3.4%); 4 patients underwent retransplantation due to thrombosis. This analysis included 6 patients aged 27 to 51 years, including 4 men and 2 women. In the early postoperative period (0–14 days), according to laboratory parameters, ultrasound Doppler, and computed tomography with a contrast agent, an impairment of the arterial blood supply of the graft was revealed, for which the patients underwent emergency X-ray image-guided surgical endovascular interventions.

Results. Restoration of adequate arterial blood supply to the liver graft was achieved in all six patients. At the time of this writing, the graft function and patency of the hepatic artery were preserved at follow-up periods of 6, 11, 12, 22 (in two patients), and 26 months with a median of 17 months. Four patients developed biliary complications that required surgical correction.

Conclusion. X-ray image-guided endovascular interventions can be considered effective and relatively safe in the treatment of patients with arterial complications after liver transplantation. The period of graft arterial ischemia should be minimized as much as possible in order to prevent biliary complications.
Phenomenon of Demikhov. At N.V. Sklifosovsky Institute (1960–1986). V.P. Demikhov and world transplantology in 1968-1969
Authors: Glyantsev S. P.
Published: December 2021

The article has reviewed the advances of Soviet and world Transplantology in the field of heart and other organ transplantation achieved by the end of the 1960s. It is shown that there were several groups of doctors and scientists who worked in the USSR dealing with the problem of experimental organ transplantation and trying to bring this experience into clinic. The group of surgeons and urologists (B.V. Petrovsky, Y.M. Lopukhin, etc.) from the Research Institute of Clinical and Experimental Surgery and the 2nd MOLGMI named after N.I. Pirogov, which had the greatest administrative resources and technical capabilities, was successfully implementing kidney transplantation into clinic. The staff of the Faculty Surgery Department (V.S. Savelyev and others) of the 2nd MOLGMI named after N.I. Pirogov developed experimental approaches to heart and liver transplantation. Surgeons from the Tuberculosis Research Institute (N.I. Gerasimenko and others) were dealing with in lung auto- and homotransplats in experiment. All those studies were conducted in close contact with the Department of Operative Surgery and Topographic Anatomy of the 2nd MOLGMI named after N.I. Pirogov (G.E. Ostroverkhov) and the Research Laboratory for Organ Transplantation established at that Department (Y.M. Lopukhin). The leading position in heart transplantation in the country belonged to the Vishnevsky Institute of Surgery (A.A. Vishnevsky, etc.). Surgeons of the MMA named after S.M. Kirov (I.S. Kolesnikov, etc.) rendered a great assistance to the Institute. Apart from these institutions, the Organ Transplantation Laboratory (headed by V.P. Demikhov) worked at N.V. Sklifosovsky Research Institute for Emergency Medicine; it had gained a huge experimental experience, but had very modest opportunities to purchase equipment and pharmaceuticals, to conduct laboratory and morphological studies, having practically no prospects for introducing the results of its research into clinic. Meanwhile, the world clinical Transplantation continued to develop successfully, which was reflected in the materials of the 2nd International Symposium on Heart Transplantation held in 1969 in Montreal (Canada).
