A partir delas, foi possível observar que as categorias de Impostos e de Obras Públicas foram as que apresentaram resultados mais expressivos para este estudo. Os resultados encontrados contribuíram para a identificação e a valoração de exemplares que integram o patrimônio cultural da cidade, repercutindo nas tomadas de decisão que visam orientar as políticas públicas voltadas à salvaguarda do patrimônio cultural hervalense.
Determining the Training Needs Regarding the “Structuring Dimension” in the Individual Counselling Process
Authors: Bek Hafız , Gülveren Hakan
Published: July 2022

The psychological counselling process is commenced with structuring. Since the clients do not know what to do or what is expected of them in psychological counselling sessions, counsellors are required to provide information about the process in this dimension. 20 students (12 female, 8 male) who took Individual Counselling Course in the spring term of 2019 - 2020 academic year constitute the study group. Phenomenology method, one of qualitative research methods, was employed in the current study. Audio recordings of counsellor candidates from eight sessions were classified according to categories based on the sub-divisions of the structuring dimension. In light of the data obtained, the training needs and qualification levels of counsellor candidates were attempted to be revealed. When the results of the sub-division of information about the counselling, the first stage of the structuring dimension, were examined, it was observed that counsellor candidates did not have a significant problem in terms of this skill. In the sub-division of explaining the processes and principles of structuring dimension, counsellor candidates were observed to have difficulty in the skill to provide accurate information about the process. On the contrary, at the end of the supervision during the second and third sessions, it was indicated that, in terms of the related skill, their qualification levels increased and there were no problems in the subsequent sessions. Concerning the data regarding the sub-division of the objective of structuring dimension, it was determined that the counsellor candidates had difficulty in the skill to clarify the boundaries of the counselling process. Therefore, certain training regarding this skill is required.

Organizing Management of Early Childhood Education Institution: A Case Study at One Raudhatul Athfal in Palembang
Authors: Marlina Leny
Published: July 2022

This study aimed to analyze the organizing management of early childhood education at one Raudhatul Athfal in Palembang, especially the input component as an effort to improve and develop the management of the institution. This study used qualitative case study research with inductive logic of thinking to analyze about the situation or meaning of the characteristics of the object under study. The main informant was the principal of Raudhatul Athfal and the supporting informants were teachers, parents and the school committee. Data collection techniques were conducted by doing observation, interviews, and documentation. Meanwhile, the data analysis technique followed the flow model (data reduction, data display, and data verification). The results showed that the organizing management at the Raudhatul Athfal especially on the input components (school vision and mission, goals, human resources (students and teachers)), curriculum, facilities, infrastructure (equipment, and equipment) and financing had been carried out, although there were still things that needed to be addressed, such as the recruitment system of teacher which was not yet systematic. In this study, the researcher saw that in addition to the management of organizing inputs, other factors that influenced the development and progress of this institution were the management system that was less clear from the foundation, where management of some school activities or programs were already independent, but for the procurement of needs or costs of activities they were still not independent because they had to coordinate first so that the school was less flexible. In other words, the school needed a common vision of all members starting from foundation managers, school principals, as well as teachers and students.

Authors: Putra Heldy Ramadhan , Retnaningsih Woro , Nugroho Arif
Published: July 2022

This study aims to shed some light on the use of Project Based Learning (PBL) in teaching translation at an Islamic university. Involving 35 students of English department, a Classroom Action Research (CAR) in two cycles and semi-structured interview were adopted to examine the effectiveness of PBL and to explore the students’ perspectives toward strengths and weaknesses of the method. The results revealed that PBL was proven effective to enhance students’ translation performances (p-Value 0.000 < 0.05). The results further demonstrated that PBL was an effective method to develop students’ soft-skills such as communicative competence, critical thinking, problem solving ability, and creativity. However, the students also pointed out that doing translation project using PBL method required sufficient time allocation since it based on contexts and experiences as in real working environments. The results contribute to providing fruitful insights for teachers and college authorities to incorporate PBL as an alternative method for teaching translation. Last but not least, it is a worth saying that project based learning is a promising method for teaching translation at university level.

Therapeutic efficacy of retroviral replicating vector (RRV)-mediated prodrug activator gene therapy has been demonstrated in a variety of tumor models, but clinical investigation of this approach has so far been restricted to glioma and gastrointestinal malignancies. In the present study, we evaluated replication kinetics, transduction efficiency, and therapeutic efficacy of RRV in experimental models of lung cancer. RRV delivering GFP as a reporter gene showed rapid viral replication in a panel of lung cancer cells in vitro, as well as robust intratumoral replication and high levels of tumor transduction in subcutaneous and orthotopic pleural dissemination models of lung cancer in vivo. Toca 511 (vocimagene amiretrorepvec), a clinical-stage RRV encoding optimized yeast cytosine deaminase (yCD) which converts the prodrug 5-fluorocytosine (5-FC) to the active drug 5-fluorouracil (5-FU), showed potent cytotoxicity in lung cancer cells upon exposure to 5-FC prodrug. In vivo, Toca 511 achieved significant tumor growth inhibition following 5-FC treatment in subcutaneous and orthotopic pleural dissemination models of lung cancer in both immunodeficient and immunocompetent hosts, resulting in significantly increased overall survival. This study demonstrates that RRV can serve as highly efficient vehicles for gene delivery to lung cancer, and indicates the translational potential of RRV-mediated prodrug activator gene therapy with Toca 511/5-FC as a novel therapeutic strategy for pulmonary malignancies.

Published: July 2022

Orbital fractures are a common finding in facial trauma and serious complications may arise when orbital reconstruction is not done properly. The virtual planning can be used to manufacture patient-specific titanium orbital implants (PSI) through the process of selective laser melting. This method is currently considered the most accurate technique for orbital reconstruction. Even with the most accurate tehniques of bone reconstruction, there are still situations where enophthalmos is present after reconstruction which may be produced by intraorbital soft tissue atrophy. The aim of this paper was to evaluate the orbital soft tissue after postraumatic reconstruction of the orbital walls fractures. 10 patients diagnosed with unilateral orbital fractures were included in this study. A CT scan of the head region with thin slices (0.6mm) and soft and bone tissue windows was done. After data processing, the STL files were exported and the intraorbital fat tissue volume and the muscular tissue volume were masured. The volumes of affected orbit tissues were compared with the volumes of the healthy orbit tissues for each patient. Our findings conclude that a higher or a lower grade of fat and muscular tissue loss is present in all cases of reconstructed orbital fractures.

Mutations within the hepatitis B virus (HBV) genome have been associated with rapid progres-sion to hepatocellular carcinoma (HCC); however, there is limited information regarding the prevalence and impact of these mutations in most of sub-Saharan Africa, including Botswana. We aimed to determine the prevalence of HBV mutations known to be associated with progression to HCC using a retrospective, cross-sectional analysis of 48 previously generated HBV sequences from adults with concomitant HBV/HIV initiating HIV antiretroviral therapy in Botswana. The sequences were aligned with reference sequences, and HCC-associated mutations were manually identified using BioEdit. Sixteen (33.3 %) of 48 participant samples had 20 HCC-associated mu-tations. Seven HCC mutations were present in the core region, 4 in the preCore region, 7 in the X region, and one mutation in the surface region, as well as deletions within the preSurface 1 region. Seven of the 16 participants (43.8%) had multiple HCC-associated mutations. There were also previously uncharacterized mutations at positions with known HCC-associated mutations. HCC-associated mutations were common in this cohort; hence, some participants may require close clinical monitoring as they might be more prone to rapid disease progression. Other functionally uncharacterized polymorphisms were also detected and require characterization in future studies.

Published: July 2022

The freshwater snail genus Bulinus plays a vital role in transmitting parasites of the Schistosoma haematobium group. A hybrid schistosome between S. haematobium and S. mattheei has been recently detected using DNA-based identification methods in school children along the Lake Malawi shoreline in Mangochi District. This finding raised the need for contemporary revaluation of local interactions between schistosomes and snails, with a particular focus on snail species within the Bulinus africanus group. In 2017 and 2018, malacological surveys sampled several freshwater sites in Mangochi District. Collected snails (n= 250) were characterised using cytochrome oxidase subunit 1 gene (cox1), with DNA barcoding of the ‘Folmer’ region and a rapid PCR-RFLP typing assay with double digestion with HaeIII and SacI restriction enzymes. DNA cox1 sequence analysis, with phylogenetic tree construction, suggested the presence of at least three Bu. africanus group taxa in Lake Malawi, Bu. globosus, alongside first reports of Bu. africanus and Bu. angolensis, which can be differentiated by PCR-RFLP methods. In addition, A total of 30 of the 106 Bu. africanus group snails (28.30%) were positive to the Schistosoma-specific screen using real-time PCR methods. This study provides new insight into the recent changes in the epidemiology of urogenital schistosomiasis as likely driven by a new diversity of Bu. africanus group snails within the lake

Authors: Kondinski Aleksandar , Banerjee Abhishek , Mal Sib Sankar
Published: July 2022

Lacunary polyoxometalates (POMs) are negatively charged metal−oxo clusters, formally obtained from plenary topologies via fragment removal. Owing to the fragment removal, the lacunary POMs archetypes are rich in nucleophilic terminal oxo ligands, making them suitable for post-synthetic coordination with various heterometals. Trilacunary heteropolytungstates (het-ero-POTs) based on bowl-shaped {W9O30} framework incorporating a central lone-pair containing {XO3} hetergroup (X = AsIII, SbIII, and BiIII) function as all-inorganic scaffolds that in the presence of d-block metal cations typically construct sandwich-like dimers of Hervé and/or Krebs. Herein we review the preparative approaches, compositional and magnetic versatility of the constructing Hervé and Krebs type dimers and discuss prospective use as POMtronics.

Published: July 2022

Rett syndrome (RTT) is a rare disease and one of the most abundant causes for intellectual disa-bilities in females. Single mutations in the gene coding for methyl-CpG-binding protein 2 (MECP2), are responsible for the disease. MeCP2 regulates gene expression as a transcriptional regulator as well as through epigenetic imprinting and chromatin condensation. Consequently, numerous biological pathways on multiple levels are influenced however, the exact molecular pathways from genotype to phenotype are currently not fully elucidated. Treatment of RTT is purely symptomatic where no curative options for RTT have yet to reach the clinic. The paucity of this is mainly due to an incomplete understanding of the underlying pathophysiology of the dis-order with no clinically useful common disease drivers, biomarkers or therapeutic targets being identified. With the premise of identifying universal and robust disease drivers and therapeutic targets, here we interrogated a range of RTT transcriptomic studies spanning different species, models and MECP2 mutations. A meta-analysis using RNA sequencing data from brains of RTT mouse models human post-mortem brain tissue and patient-derived induced pluripotent stem cells (iPSC) neurons was performed using Weighted Gene Correlation Network Analysis (WGC-NA). This study identified a module of genes common to all datasets with the following ten hub genes driving the expression ATRX, ADCY7, ADCY9, SOD1, CACNA1A, PLCG1, CCT5, RPS9, BDNF and MECP2. Here we discuss the potential benefits of these genes as therapeutic targets.
Multi-fidelity Model Calibration in Structural Dynamics using Stochastic Variational Inference on Manifolds

Published: July 2022

Bayesian techniques for engineering problems, that rely on Gaussian process (GP) regression, are known for their ability to quantify epistemic and aleatory uncertainties and for being data efficient. The mathematical elegance of applying these methods usually comes at a high computational cost when compared to deterministic and empirical Bayesian methods. Furthermore, using these methods becomes practically infeasible in scenarios characterized by a large number of inputs and thousands of training data. The focus of this work is on enhancing Gaussian Process-based metamodeling and model calibration tasks, when the size of the training datasets is significantly large. To achieve this goal, we employ a stochastic variational inference algorithm that enables rapid statistical learning of the calibration parameters and hyperparameter tuning, while retaining the rigor of Bayesian inference. The numerical performance of the algorithm is demonstrated on multiple metamodeling and model calibration problems with thousands of training data.
A Review of the Pharmacognostical and Pharmacological Properties of The Kalanchoe Plant as Treatment for Dermatological-Related Conditions
Authors: dela Cruz Fawzijamil
Published: July 2022

The Kalanchoe genus is composed of more than 100 species that usually thrive in tropical environments, which have been used in folkloric medicine to treat various illnesses, including dermatological conditions. With this, the present study assesses the pharmacognostical and pharmacological properties of different species of the Kalanchoe genus as elements for a potential treatment for dermatological-related conditions, from findings of existing literature and studies. It was analyzed that the Kalanchoe pinnata plant, or one of the most common species of Kalanchoe, have been observed to have distinct morphological and microscopic characteristics. Further, it was discovered that different species of Kalanchoe have anti-inflammatory, antioxidant, antibacterial, and wound healing properties, which enable the plant to be used for dermatological products that are available to the market. With this, it is recommended that further studies be conducted in other understudied species of Kalanchoe regarding their pharmacological properties, as well as the use of other structures of the Kalanchoe plant for treatment of various dermatological conditions.

Published: July 2022

It is no news that the COVID–19 pandemic has affected many persons in different ways. As the number of reported cases rises across the globe, efforts are geared towards production and administration of effective vaccines for the disease. However, many developing countries are faced with the dilemma of how to slow the spread and flatten the curves of the disease as the available vaccines are not enough. Interestingly, the dynamics of the disease can be analysed to get useful insights to enhance the making of suitable preventive policies that will slow the spread, ultimately flatten the curves of the disease and also help in managing any future occurrence. In this work, the aim is to analyse the dynamics, and estimate the basic reproduction number of the second wave of the pandemic in Nigeria using a Susceptible-Infected-Recovered-Deceased (SIRD) compartmental–based model. The dynamics of the disease is described by a system of nonlinear ordinary differential equations. The model takes into consideration the current control policies in place - social distancing, mask usage, personal hygiene and quarantine. Available data provided by Nigeria Centre for Disease Control (NCDC), World Health Organization (WHO) and Wolfram Data Repository were used for the computations. The Quasi–Newton algorithm was implemented in fitting the proposed model to the available data and a sensitivity analysis was presented. Major parameters - effective contact rate, average recovery time, average mortality rate, and overall effectiveness of the control policies - influencing the dynamics of the disease, and the basic reproduction numbers were estimated. The turning points of the disease during the second wave were also obtained. The proposed model gave estimated values for the parameters influencing the spread of the disease. Also, the measure of the overall effectiveness of the current control policies gave insight into how effective the measures are.
New Control Parametrization Strategy for Flexible Feed Drives

This paper presents a novel parametrization strategy for optimal contouring control of flexible feed drives. The aim of the new strategy is to maximize the structural damping of the drive and counteract the deformations of the structure. Using a simplified flexible multibody model, the analytical relationships for the design of velocity and position control gains were derived. This results in a controller bandwidth increase of up to 20% compared to the previous state-of-the-art in parametrization of standard cascaded controllers. Through analytical and numerical calculations, it was demonstrated that such an increase is feasible without a decrease in structural damping if the position and velocity controller gains are both considered. Furthermore, it is shown that the ratio between the position and velocity loop gains influences the quasistatic deformation between the encoder and tool center point (TCP). A formula for the optimal choice of the ratio was derived to compensate for the error. This leads to a new straightforward step-by-step approach for axis controller setting, which is then applied to a test bench and its simulation model. It can be shown that the new parametrization strategy leads to a significant reduction in path error at the TCP. Importantly, the analytical approach should simplify the task of setting up a standard cascaded controller significantly by avoiding time-consuming iterations.
Pneumatically-Controlled Linear Actuator Using Pressure-Resistant, Thin-Walled Metal Bellows and its Application
Authors: Sato Yasukazu ,   Yokohama National University  79-5 Tokiwadai, Hodogaya-ku, Yokohama, Kanagawa 240-8501, Japan, Shimbori Takeyoshi
Published: July 2022

The use of pneumatics has led to the development of a linear actuator that incorporates pressure-resistant metal bellows. This pressure-resistant bellows device is airtight and capable of considerable expansion. Conventional bellows devices are susceptible to bending stresses at the folds because high air pressure tends to crush the curvature of the bellows there. Therefore, their application only uses a 0.1 MPa difference in inner/outer pressure. The pressure-resistance of the bellows device is improved by the installation of viscoelastic rings in its folds, rings which reduce the bending stress caused by the high air pressure at the thin-walled inner folds. As a result, the pressure resistance is increased by 0.7 MPa. This paper uses a theoretical formulation and a finite element analysis approach in reporting the improvement in pressure resistance made by the installation of the viscoelastic rings. Furthermore, the actuator with pressure-resistant, thin-walled metal bellows is used to control the posture and damping force of a vehicle’s active suspension.

Published: July 2022

The tap-water-driven McKibben artificial muscle has many advantages and is expected to be applied in mechanical systems that require a high degree of cleanliness. However, the muscle has strong asymmetric hysteresis characteristics that depend on the load, and these problems prevent its widespread use. In this study, a novel control method, model predictive control with a servomechanism based on inverse optimization with adaptive model matching, was developed. This control method was applied to the muscle by using a high-precision mathematical model employing an asymmetric Bouc-Wen model. The experimental results show that the proposed approach achieved a high tracking performance for a given reference frequency, with a mean absolute error of 0.13 mm in the steady-state response and with easier controller tuning. Furthermore, the contributions of the controller elements of the proposed method were evaluated. The results show that the contribution of the adaptive system was higher than that of the servo system. Furthermore, the effectiveness of adaptive model matching was verified.

A multi-degree-of-freedom, spherical ultrasonic motor (MDOF-SUSM) has been proposed to reduce the size and weight of actuator systems capable of MDOF motion. The MDOF-SUSM is expected to be used in manipulators and spacecraft because of its noiseless, self-holding, and non-magnetic properties. Previous studies have shown the feasibility of the MDOF-SUSM using a spherical stator, but the weight of the device was problematic. This paper describes a hemispherical shell stator devised to reduce the weight of the MDOF-SUSM. For the prototype stator, a suitable vibration mode search and an excitation method were investigated using finite element analysis (FEA). A combination of l2m1-mode and l1m0-mode was selected and found to be excitable by an arched piezoelectric ceramic plate bonded to the opening. A stator support mechanism using four tuning forks was also devised. The vibration characteristics of the prototype stator were experimentally investigated. The results of FEA and displacement measurement confirmed the formation of multiple natural vibration modes that can be used for rotation. Rotation with three degrees of freedom was confirmed to be possible by combining the vibration modes. In short, a hemispherical shell stator for the MDOF-SUSM was created, and it is lighter in weight than the MDOF-SUSM that used a spherical stator.

Gold-bearing polymetallic ores of the Novo-Shirokinsky deposit (further NShD) are complex, containing other valuable components besides gold and silver, which include lead, zinc, copper, iron, etc. According to the content of sulfides in the ores, they belong to the moderate sulfide type. The main feature of the material composition of ores NShD: expressed multicomponent content of valuable minerals; proximity of flotation properties of shared minerals; especially valuable mineral in ores, in addition to gold and silver, is copper, which is mainly concentrated in lead concentrate. The highest technological indicators of ore beneficiation are achieved when they are enriched according to a collective technological scheme. The technological scheme of ore beneficiation at the plant is shown in fig. 1. A lead-copper concentrate is obtained, which, as a rule, is subsequently sent for subsequent selective flotation. The factory produces two main concentrates - lead and zinc (corresponding to TU 07.29.15-002-24722376-2018, TU 1725-001-24722376-2011). This work is aimed at increasing the complexity of the use of NShD polymetallic ores in order to justify the possibility of additional production of copper concentrate at the plant. The object of the study – gold-bearing polymetallic ores of the Novo-Shirokinsky deposit. The subject of the study – flotation process of ore beneficiation as the basis for obtaining copper concentrate by constructing effective technological schemes for the polymetallic ores’ processing. The main idea of the work – sequential extraction of copper from lead concentrates using retreatments and optimal operating parameters of the flotation process

The purpose of this study is to examine the changes in preschool teachers' perceptions of communication disorders after an educational program called the Early Screening for Communication Disorders Program(ESC), which was developed in this study to provide a better understanding of the communication disorders and to help the screening process of it. A total of 58 preschool teachers working at national and public daycare centers in Busan participated in this study. The results of this study are summarized as follows. The preschool teachers' overall understandings and perceptions of communication disorders were statistically higher after the ESC program. Also, all questions related to the satisfaction of preschool teachers with the ESC education program were rated 4.50 or higher on a 5-point scale. This study suggests that more educational programs related to communication disorders should be available for preschool teachers and it also provides supporting data to help the screening process of communication disorders in young children.
Comparing riskiness of exchange rate volatility using the Value at Risk and Expected Shortfall methods
Authors: Ndlovu Thabani , Chikobvu Delson
Published: July 2022

This paper uses theValue at Risk (VaR) and the Expected Shortfall (ES) to compare the riskiness of the two currency exchange rate volatility, namely BitCoin against the US dollar (BTC/USD) and the South African Rand against the US dollar (ZAR/USD). The risks calculated are tail-related measures, so the Extreme Value Theory is used to capture extreme risk more accurately. The Generalized Pareto distribution (GPD) is assumed under Extreme Value Theory (EVT). The family of Generalized Autoregressive Conditional Heteroscedasticity (GARCH) models was used to model the volatility-clustering feature. The Maximum Likelihood Estimation (MLE) method was used in parameter estimation. Results obtained from the GPD are compared using two underlying distributions for the errors, namely: the Normal and the Student-t distributions. The findings show that the tail VaR on the BitCoin averaging 1.6 and 2.8 is riskier than on South Africa’s Rand that averages 1.5 and 2.3 at 95% and 99%, respectively. The same conclusion is made about tail ES, the BitCoin average of 2.3 and 3.6 is higher (riskier) than the South African Rand averages at 2.1 and 2.9 at 95% and 99%, respectively. The backtesting results confirm the model adequacy of the GARCH-GPD in the estimation of VaR and ES, since all p-values are above 0.05.
Determinants of sustainability reporting: Empirical evidence from East African Countries
Authors: Maama Haruna , Gani Shenaaz
Published: July 2022

Sustainability reporting is gaining attention among industry professionals and academics. However, it has been criticized since it fails to represent the proper reporting practices of firms, with this being described as symbolic in form. Regardless of this criticism, management of firms in East Africa is increasingly adopting sustainability reporting, despite being voluntary. Therefore, the paper analyzed the determinants of sustainability reporting of East African firms. Eight years of annual reports of 74 listed firms in Kenya, Tanzania, and Uganda were used. Random and fixed effect regression techniques were employed for the estimates. The study found that firms’ specific characteristics such as size, Tobin’s Q, industry affiliation, and ownership structure have a positive and significant influence on firms’ management to adopt sustainability reporting practices. In addition, it was suggested that firms with a more considerable asset and Tobin’s Q provide more sustainability reporting than those with smaller assets and Tobin’s Q. The results further showed that firms’ age and return on assets do not influence sustainability reporting. The evidence further demonstrated that firms with foreign parent companies significantly disclosed more sustainability information than local firms. The paper concludes that the firm-specific characteristics influence their sustainability reporting practice. The study provides policy implications because it can assist the governments and regulators in these countries in guiding the firms’ reporting practices.
El orden del amor en la Divina Comedia
Authors: Abbate Stefano
Published: July 2022

A través de algunas intuiciones de Max Scheler acerca del ordo amoris, se aborda esta cuestión en el pensamiento de Dante Alighieri, especialmente en la Divina Comedia. La obra del poeta florentino se vertebra sobre la ordenación del intelecto y de la voluntad al bien del hombre, así como en la búsqueda del primer amor que mueve esta inclinación del hombre. A través de varios ejemplos tomados de la Divina Comedia se pretende presentar esta cuestión fundamental en la obra mayor de Dante.

Objective: to study the features of the course of the wound process both with the isolated use of hexethidine and photoditazine, and in combination with ultrasound therapy. Materials and Methods. The in vivo experiment was performed on 144 animals (male Wistar rats) divided into 4 equal groups. A purulent wound model (S=150mm2) was formed in all rats, which was treated with the studied combinations with and without ultrasound therapy. The percentage of area reduction, healing rate, microbial contamination, and morphological picture of wounds were evaluated. Results. In the groups treated with the combination we developed, complete wound healing had occurred by 15 days. The greatest activity was in phase I of the wound process, which is confirmed by the maximum wound healing rate (1-5 days from the start of treatment), as well as by the morphological picture. At the same time, in the group with the use of ultrasound therapy the indices of microbial siltation and percentage of area reduction were reliably better in comparison with the isolated use of the combination. Conclusion. The developed combinations have a positive effect in the treatment of purulent wounds, speeding up the healing process and reducing microbial contamination.

Published: July 2022

Background and Objective:

Severe acute respiratory syndrome coronavirus
2 (SARS-CoV-2) infection commonly leads to neurologic manifestations. In the present
review, we aimed to investigate potential neuroimaging markers of early diagnosis and
prognosis of neurologic manifestations in COVID-19.

Methods:

Our study was registered in the Prospective Register of Systematic Reviews
(PROSPERO) under the protocol CDR42021265443. Based on the Preferred Reporting
Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we selected 51
studies for whole-manuscript analysis.

Results:

Magnetic resonance imaging (MRI) was the most common imaging method.
The pattern, sites of lesion, signs, and symptoms of neurologic injury varied. Such manifestations
possibly resulted from a direct viral infection or, most likely, from indirect
mechanisms including coagulation disturbances, hypoxemia, and immunological responses.

Conclusion:

The heterogeneity of the studies precludes any generalization of the findings.
Brain MRI is the most informative imaging exam. Population studies, including the
entire spectrum of COVID-19 are missing. There is still a need for future population
studies evaluating neurologic manifestations of all COVID-19 severities acutely and
chronically.
