Authors: Nardez Taina Maiza Bilinski , Guijo Laura Mochiatti , Lucas Priscila de Araújo , Cardoso Ana Cláudia Vieira 
Published: March 2021

Abstract
Introduction Central auditory processing disorder (CAPD) has been diagnosed through behavioral tests. Moreover, screening tools as validated questionnaires may contribute to identify individuals at risk for this disorder, including adolescents.
Objective (1) to characterize and compare adolescents' self-perception regarding their auditory behavior with their parents' perception; (2) to verify their agreement with behavioral evaluation of central auditory processing (CAP).
Methods Cross-sectional, prospective, and descriptive study, in which 40 adolescents and 40 parents of both genders participated. All participants answered the scale of auditory behaviors questionnaire, and the behavioral evaluation of CAP was conducted with the adolescents. Findings were analyzed descriptively and inferentially, with a significance level of 5% (p ≤ 0.05) and application of the following tests: Test for equality of two proportions, Chi-squared, and Kappa concordance index.
Results Most adolescents rated their auditory behavior as “low risk” for CAPD while their parents rated it as “typical.” When comparing adolescents' self-perception and parents' perception about the auditory behavior with the behavioral evaluation outcome, a statistically significant difference was observed only in adolescents' self-perception. The results of the behavioral evaluation indicated that 42.5% of the adolescents showed alterations. The concordance index between adolescents' self-perception and parents' perception of auditory behavior showed a significant (minimal) difference.
Conclusion Most adolescents were able to perceive difficulties regarding their auditory behavior and characterized it as “low risk” for CAPD, but the same did not occur regarding their parents. There was agreement only between the adolescents' self-perception and their performance in the behavioral evaluation of CAP.

Published: March 2021

Abstract
Introduction Tinnitus is the perception of sound in the absence of external sound stimulation. There is a general agreement that it is a direct consequence of irreversible and permanent cochlear damage.
Objectives The present work is designed to study the distortion product otoacoustic emissions (DPOAEs) in tinnitus patients with normal hearing in comparison with normal hearing control and to study any possible correlation between DPOAEs recording and patients' complaints.
Methods The present study included 80 subjects divided into 2 groups: Control group: consisted of 30 normal-hearing adults not complaining of tinnitus and Study group: consisted of 50 normal-hearing adults complaining of tinnitus. The methodology includes full audiological history, otoscopic examination, basic audiological evaluation, DPOAEs including both DP-gram and DPOAEs input/output functions.
Results Basic audiological evaluation showed within normal hearing sensitivity in both groups, however, with significant higher hearing thresholds in tinnitus patients at all frequency ranges. The Tinnitus Handicap Inventory Questionnaire showed mean scores of 35.2 ± 16.9 in the study group. The DP-gram showed higher amplitudes in the control group when compared with tinnitus patients. The DPOAEs input-output functions at different frequencies (1, 2, 4 and 6kHz) also showed higher amplitudes at all frequencies and different input levels. The slope of the I/O function tends to be steeper in tinnitus cases.
Conclusion Patients with tinnitus might have neural dysfunction at either the level of the cochlea, as shown in reduced DPOAE levels, and changes in the normal DP-I/O function recorded in the present work.
Anastomosis Patterns between the Median and Ulnar Nerves in the Upper Limbs
Authors: Felippe Marcelo Medeiros , Rodrigues Renan Salomão , Santana Thais Baccarini 
Published: March 2021

AbstractThere are four types of anastomoses between the median and ulnar nerves in the upper limbs. It consists of crossings of axons that produce changes in the innervation of the upper limbs, mainly in the intrinsic muscles of the hand. The forearm has two anatomical changes – Martin-Gruber: branch originating close to the median nerve joining distally to the ulnar nerve; and Marinacci: branch originating close to the ulnar nerve and distally joining the median nerve. The hand also has two types of anastomoses, which are more common, and sometimes considered a normal anatomical pattern – Berrettini: Connection between the common digital nerves of the ulnar and median nerves; and Riche-Cannieu: anastomosis between the recurrent branch of the median nerve and the deep branch of the ulnar nerve. Due to these connection patterns, musculoskeletal disorders and neuropathies can be misinterpreted, and nerve injuries during surgery may occur, without the knowledge of these anastomoses. Therefore, knowledge of them is essential for the clinical practice. The purpose of the present review is to provide important information about each type of anastomosis of the median and ulnar nerves in the forearm and hand.

Published: March 2021

Abstract
Introduction Malignant mesonephric tumors are uncommon in the female genital tract, and they are usually located where embryonic remnants of Wolffian ducts are detected, such as the uterine cervix. The information about these tumors, their treatment protocol, and prognosis are scarce.
Case report A 60-year-old woman with postmenopausal vaginal bleeding was initially diagnosed with endometrial carcinoma. After suspicion co-testing, the patient underwent a loop electrosurgical excision of the cervix and was eventually diagnosed with mesonephric adenocarcinoma. She was subjected to a radical hysterectomy, which revealed International Federation of Gynecology and Obstetrics (FIGO) IB1 stage, and adjuvant radiotherapy. The follow-up showed no evidence of recurrence after 60 months.
Conclusion We present the case of a woman with cervical mesonephric adenocarcinoma. When compared with the literature, this case had the longest clinical follow-up without evidence of recurrence, which reinforces the concept that these tumors are associated with a favorable prognosis if managed according to the guidelines defined for the treatment of patients with cervical adenocarcinomas. Though a rare entity, it should be kept in mind as a differential diagnosis for other cervical cancers.

Abstract
Objective To investigate the effect of closure types of the anterior abdominal wall layers in cesarean section (CS) surgery on early postoperative findings.
Methods The present study was designed as a prospective cross-sectional study and was conducted at a university hospital between October 2018 and February 2019. A total of 180 patients who underwent CS for various reasons were enrolled in the study. Each patient was randomly assigned to one of three groups: Both parietal peritoneum and rectus abdominis muscle left open (group 1), parietal peritoneum closure only (group 2), and closure of the parietal peritoneum and reapproximation of rectus muscle (group 3). All patients were compared in terms of postoperative pain scores (while lying down and during mobilization), analgesia requirement, and return of bowel motility.
Results The postoperative pain scores were similar at the 2nd, 6th, 12th, and 18th hours while lying down. During mobilization, the postoperative pain scores at 6 and 12 hours were significantly higher in group 2 than in group 3. Diclofenac use was significantly higher in patients in group 1 than in those in group 2. Meperidine requirements were similar among the groups. There was no difference between the groups' first flatus and stool passage times.
Conclusion In the group with only parietal peritoneum closure, the pain scores at the 6th and 12th hours were higher. Rectus abdominis muscle reapproximations were found not to increase the pain score. The closure of the anterior abdominal wall had no effect on the return of bowel motility.

Abstract

Objective. Electrical vagus nerve stimulation (VNS) has the potential to treat a wide variety of diseases by modulating afferent and efferent communication to the heart, lungs, esophagus, stomach, and intestines. Although distal vagal nerve branches, close to end organs, could provide a selective therapeutic approach, these locations are often surgically inaccessible. In contrast, the cervical vagus nerve has been targeted for decades using surgically implantable helix electrodes to treat epileptic seizures and depression; however, to date, clinical implementation of VNS has relied on an electrode with contacts that fully wrap around the nerve, producing non-selective activation of the entire nerve. Here we demonstrate selective cervical VNS using cuff electrodes with multiple contacts around the nerve circumference to target different functional pathways. Approach. These flexible probes were adjusted to the diameter of the nerve using an adhesive hydrogel wrap to create a robust electrode interface. Our approach was verified in a rat model by demonstrating that cervical VNS produces neural activity in the abdominal vagus nerve while limiting effects on the cardiovascular system (i.e. changes in heart rate or blood pressure). Main results. This study demonstrates the potential for selective cervical VNS as a therapeutic approach for modulating distal nerve branches while reducing off target effects. Significance. This methodology could potentially be refined to treat gastrointestinal, metabolic, inflammatory, cardiovascular, and respiratory diseases amenable to vagal neuromodulatory control.
Effect of force accuracy on hemodynamic response: an fNIRS study using fine visuomotor task

Published: March 2021

Abstract

Objective. Despite converging neuroimaging studies investigating how neural activity is modulated by various motor related factors, such as movement velocity and force magnitude, little has been devoted to identifying the effect of force accuracy. This study thus aimed to investigate the effect of task difficulty on cortical neural responses when participants performed a visuomotor task with varying demands on force accuracy. Approach. Fourteen healthy adults performed a set of force generation operations with six levels of force accuracy. The participants held a pen-shaped tool and moved the tool along a planar ring path, meanwhile producing a constant force against the plane under visual guidance. The required force accuracy was modulated by allowable tolerance of the force during the task execution. We employed functional near-infrared spectroscopy to record signals from bilateral prefrontal, sensorimotor and occipital areas, used the hemoglobin concentration as indicators of cortical activation, then calculated the effective connectivity across these regions by Granger causality. Main results. We observed overall stronger activation (oxy-hemoglobin concentration, p = 0.015) and connectivity (p < 0.05) associated with the initial increase in force accuracy, and the diminished trend in activation and connectivity when participants were exposed to excessive demands on accurate force generation. These findings suggested that the increasing task difficulty would be only beneficial for the mental investment up to a certain point, and above that point neural responses would show patterns of lower activation and connections, revealing mental overload at excessive task demands. Significance. Our results provide the first evidence for the inverted U-shaped effect of force accuracy on hemodynamic responses during fine visuomotor tasks. The insights obtained through this study also highlight the essential role of inter-region connectivity alterations for coping with task difficulty, enhance our understanding of the underlying motor neural processes, and provide the groundwork for developing adaptive neurorehabilitation strategies.

Published: March 2021

Abstract
The article is devoted to the application of convolutional neural networks and cascade classifiers for tracking smoking facts in relation to video surveillance systems. Two methods of smoking detection are proposed. The first method involves detecting a cigarette against the background of a human face. The second method involves detecting a hand with a cigarette in it. On the basis of the proposed methods, software for a video surveillance system is being developed, which makes it possible to determine the facts of smoking in real time, and thereby prematurely prevent possible undesirable consequences.

This algorithm is a weighted voting algorithm that is configured using a genetic algorithm. The operation of the algorithm was tested separately on the results of modeling the temperature fields of the mammary glands, as w’cll as on real data. In addition, it was crosschecked against real data and simulation results. In these cases, the localization algorithm can achieve accuracy from 55 to 65% on test samples.
Supporting small enterprises in the context of new financial crisis of 2020: international experience
Authors: Binyaminov B A 
Published: March 2021

Abstract
Dramatic changes in the world economy since the beginning of 2020 have affected virtually all entrepreneurship industries and segments, the small enterprise segment in particular. Temporary "frozen" operation, as well as the number of small enterprises being reduced due to the coronavirus outbreak and related restrictions, may in general lead to liquidation of a significant sector share. To avoid the trend, governments of different countries seek to introduce truly unprecedented measures to support, or rather to preserve small enterprises. Despite the fact that the targets of small enterprise assistance remained the same, scopes, conditions and scales of its provision have changed. Current crisis response measures can be treated as experimental - they are not always effective, not always accessible, and do not always have a target audience and a corresponding financial and economic focus. Governments are assumed to succeed in finding the optimal program target by trial and error, the program that would be effective and actually would support small enterprises against the background of the new financial crisis of 2020. In this context, the international exchange of the best, most successful, practices is extremely important.

Authors: Zazykina L A , Bukova A A 
Published: March 2021

Abstract
The experience of implementing approaches of the green economy as an interaction and mutual influence between urban civilization and the biosphere is discussed. Sustainable urban development, based on the principles of a green economy, leads to an increase in human well-being in the long term, while not exposing future generations to significant environmental risks. The issue of sustainable development is being actively studied since currently the welfare of mankind is more and more determined by the quality of life in cities. In the future, the gap in numbers between urban and rural populations will only grow, and an increasing part of the world population will be represented by residents of urban areas. Sustainable urban development is understood as the ability of the urban environment to change, satisfying subsequent generations of residents in terms of security, convenience of living and activities, communications, logistics, infrastructure, architecture and design, with minimal costs for multiple transformations. European countries such as Sweden, Denmark and others show an increase in public investment in infrastructure consistent with the principles of sustainable development (including public transport, renewable energy, construction of energy-efficient buildings) and natural capital; Existing models for implementing the principles of the green economy and the practice of their implementation in Europe have shown that Russia needs social strategies designed to ensure alignment between social goals and existing or proposed economic strategies.

Published: March 2021

Abstract
As fishery activities is a significant producer of vital food products (17% of the world‘s protein consumption), the problem of including illegal and adulterated products in the supply chain, which can be solved with the help of innovative technology – blockchain, is of significant importance. Conducting this review, it is important to understand how the blockchain can act as a unifying structure for various international stakeholders to solve the problem of the fish products market. Based on the conducted economic analysis of various information technologies using methods of analysis and synthesis, experimentation, graphic images, as well as the use of official reports of the FAO (Food Organization of the United Nations), Rospotrebnadzor, Rosrybolovstvo, scientific and expert assessments and calculations of the implementation of information technologies in fishery activities of Russian and foreign scientists, it was proposed to introduce a technology of an effective mechanism for limiting the blockchain for fishery activities, where the result is the exclusion of “falsified information”, “illegal” and “low-quality” fish products from the moment they are caught to the moment they are put on sale.
