CHARACTERISTICS AND DYNAMICS OF NEUROLOGICAL DISORDERS AFTER COVID-19 INFECTION
Authors: Pedachenko Evgeny , Lisyany Mykola
Published: December 2022

In the review, literature presents data on neurological disorders and complications after a sustained COVID-19 infection. In the initial stages of the pandemic, headache, weakness, impaired sense of smell, cognitive dysfunction were mainly recorded, then cases of ischemic strokes, thromboembolism, dementia, acute inflammation, which indicated a specific viral damage to the vessels of the brain and hemocoagulation systems, encephalopathy were registered later, demyelinating injuries, mental disorders. Many factors and mechanisms may underlie neurological manifestations, including possibly immune reactions, when the virus damages nerve and microvascular cells and induces the formation of new neuron-specific autoantigens to which autoimmune reactions develop, and inflammatory reactions that determine the clinical course of neurological disorders.
Neurological and mental disorders with different manifestations occur both in patients in the acute phase of the disease, which requires inpatient treatment, as well as in a significant part of infected persons who did not require hospitalization for pneumonia and were treated on an outpatient basis, in patients who had a mild course of the disease, various complications also developed after clinical recovery, which received the name «prolonged covid syndrome» or «consequences after acute covid», «Long Covid».
Dynamic follow-up of patients over 6-8 and 18 months showed that the resulting nervous disorders may partially or completely disappear, while others persist for a long time. Almost all symptoms after 18 months were detected in a smaller number of observations, but the frequency of smell and taste disorders probably only decreased, almost by 2-2.5 times, which indicates, as some that is, the gradual restoration of the functions of the nervous system and reducing neuro covid symptoms. The review analyzes in detail some of the causes and mechanisms of the development of Long Covid, special attention is paid to autoimmune reactions that are activated during Covid-19, namely antigenic mimicry, the similarity of the virus and human proteins, the cytotoxic effect of anti-covid immunoglobulins, inhibition of autoimmunity reactions. The review notes that many issues of the development of neurological disorders require further study and improvement of treatment and rehabilitation methods.
Keywords: Covid 19, Long Covid, neurological manifestations and complications.

Published: December 2022

In recent times, attention has been focused on girl-child education globally and particularly in developing countries. Female-child education is very crucial for the development of any society such that any deliberate neglect of their education could cause danger for the entire society. This is so because female education has been found to have a more significant impact on poverty reduction, reduction of HIV/AIDs and provision of sustainable development. Unfortunately, many factors have been impeding girl-child education in Nigeria. The paper, therefore examined poverty as an impediment to girl-child education in Akoko, Ondo State.The paper was qualitative research. Data were obtained from 200 respondents who are mostly parents using a structured questionnaire developed by the researcher. The questionnaire was duly validated and inferential method was used to analyze the data collected. Results from the study revealed indices of poverty such as low earning of some parents, poor parental educational attainment, some parents being poor and having too many children as issues impeding girl-child education in Akoko, Ondo State that need to be addressed. It was concluded that children, respective of their gender be given equal access and opportunities of qualitative education to enable them reach their full potentials and contribute meaningfully to the development of their communities. Based on the findings of the study, it was recommended that government should make education compulsory, free and affordable to all children especially the girl-child, provision of employment opportunities to citizens to empower them to be financially stable to cater for their family need, sensitization of members of public on the number of children they could have and provision of interest free student loans especially to the girl children.

Published: December 2022

Our survey aimed to investigate how online parental behavior affects their parenting practices and how such practices may affect their family relations, their children’s social competencies, school achievements, and self–esteem. We examined a sample of 357 Greek-speaking parents (77.3% mothers and 22.7% fathers). We applied Young's (1998) Internet Addiction Questionnaire, the Alabama Parenting Questionnaire (APQ), and Kontopoulou's (2008) questionnaire to assess children's school performance and social competencies, their self-esteem, and family relationships. Our findings indicated that almost half of the participants are moderately addicted to the internet. Parental pathological internet use affects parental style and consequently impacts family relations and children's behavior. Gaining knowledge from the research data helps design and implement intervention programs to prevent and raise public awareness through psychoeducational information programs towards preventing internet addiction. Keywords: compulsive behavior, covid-19, internet addiction, online risks, parenting practices, pathological internet use.

Authors: Pasti André
Published: December 2022

La concentración de propiedad y la concentración geográfica en la comunicación son características comunes en gran parte de los países latinoamericanos, incluido el territorio argentino. El combate a la desigualdad regional en las capacidades de producir y hacer circular información e ideas, ha sido tema del programa Polos Audiovisuales Tecnológicos, política generada en el marco de la Ley de Servicios de Comunicación Audiovisual del 2009, conocida como Ley de Medios. El Programa destacaba nueve regiones del país –los Polos– y una red federal con 42 Nodos Audiovisuales para la ampliación de las condiciones para la comunicación audiovisual en las localidades, por medio de la articulación participativa de diversos agentes de dichas regiones. Este artículo analiza el Programa Polos, desde su diseño institucional hasta su implementación en el territorio argentino, buscando contribuir para la comprensión de las posibilidades de ampliación de la densidad comunicacional de los lugares con base en las políticas de comunicación.
Imaginarios geográficos y desigualdad urbana en el Área Metropolitana de Buenos Aires (Argentina)
Authors: Cravino María Cristina
Published: December 2022

El presente artículo aborda las representaciones geográficas (también denominados imaginarios urbanos) de los habitantes del Área Metropolitana de Buenos Aires sobre la región urbana. Para esto se realizaron entrevistas a vecinos de diferentes tipologías habitacionales (asentamientos populares, conjuntos de vivienda de interés social en altura y unifamiliares, barrios de clase media de casas bajas y de edificios en altura y urbanizaciones cerradas), las que fueron analizadas y dieron como resultado la predominancia de imaginarios urbanos que naturalizan las desigualdades metropolitanas. Por otra parte, observamos que se incorpora a la experiencia urbana de sus habitantes un sistema de jerarquías sociales entre barrios (u orden socio-espacial) y representaciones geográficas diferenciadas dentro de los espacios barriales.

Authors: Kelly Kelly , Susanto Androni
Published: December 2022

The purpose of this study is to determine the effect of tax aggressiveness on the financial reporting aggressiveness in Indonesia because both practices are closely related to the profits presented in the financial statements where these financial statements are the center of attention for investors and the general public. In addition, there is a Book-Tax Confirmatory variable as a moderator of the relationship between the two which is allegedly able to create a trade-off and there is also a variable operating cash flow and company size. This study uses a sample of companies on the IDX during 2017-2021 with a purposive sampling method, with the results of tax aggressiveness and book-tax confirmatory having no effect on the financial reporting aggressiveness. However, another result obtained is that operating cash flow has a significant positive effect and company size has a significant negative effect on financial reporting aggressiveness.

Authors: Teles Amanda Soares , Machado Layza De Souza , Neves Roberpaulo Anacleto
Published: December 2022

Este estudo observacional associou a idade e possíveis alterações em espermocitograma de pacientes do Laboratório Clínico da PUC Goiás (LAC). Verificou-se a existência de alterações no espermocitograma e os impactos interligados com as idades dos pacientes, e a partir disso realizou-se um levantamento bibliográfico para ponderar a frequências destas alterações também em outros estudos. Para realizar este estudo foram utilizados dados disponíveis do LAC de janeiro de 2018 à agosto de 2021. Os dados coletados foram idade, resultados gerais do espermocitograma (volume, características gerais, exame microscópico, motilidade, vitalidade, morfologia, aspecto microbiológico e exames químicos) e observações inseridas nos laudos. Em seguida, estes dados foram anexados em uma planilha no editor Microsoft Office Excel e catalogados em tabelas de resultados. A média das idades foi de 37,8 ± 8,4 anos com mínima de 18 e máxima de 59 anos. As amostras com azoospermia e oligospermia representavam cerca de 45,8% da amostragem. Os resultados deste trabalho indicaram que houve correlação entre as idades dos pacientes e alterações nos parâmetros seminais, onde foram observadas principais alterações na concentração, morfologia e motilidade predominantemente a partir dos 40 anos. Apesar de o espermograma ser capaz de fornecer diversas informações relevantes sobre a saúde dos órgãos reprodutores masculinos, este exame não é apto para ser um indicador de diagnóstico de fertilidade. Pois para realizar esta avaliação é preciso ser feita uma investigação mais detalhada com dados de anamnese, análise endócrina e genéticas, exames clínicos, entre outros.

DP 0271 - A Century of regional inequalities in Brazil
Authors: Carlos Ramos Magalhães João , Jorge Holanda Alves Pedro
Published: December 2022

This work calculates coefficients of spatial inequalities of wealth amongst Brazilian municipalities, for each year for the period from 1920 to 2016, states of the federation, from 1939 to 2017, and amongst municipalities from each of the five Brazilians’ macro-regions, from 1920 to 2016. The use of non-parametric statistics reveals rough short-term paths of inequalities, and the occurrence of U-shaped relationships between spatial inequalities and the level of per capita GDP, known as the Williamson’s Curve (1965). Decomposition of the changes in the Gini coefficients show intense rank turbulence and leapfrogging over richer municipalities, from 1920 to 1970. Although the coefficients confirmed a long-term convergence trend in spatial inequalities, since 1970, there have been significant differences between macro-regional spatial inequalities dynamics, and a worrying switch to divergence in the Southeast, since in 1996.
Conditions for Proton Temperature Anisotropy to Drive Instabilities in the Solar Wind
Authors: Opie Simon , Verscharen Daniel , Chen Christopher H. K. , Owen Christopher J. , Isenberg Philip A.
Published: December 2022

Using high-resolution data from Solar Orbiter, we investigate the plasma conditions necessary for the proton temperature-anisotropy-driven mirror-mode and oblique firehose instabilities to occur in the solar wind. We find that the unstable plasma exhibits dependencies on the angle between the direction of the magnetic field and the bulk solar wind velocity which cannot be explained by the double-adiabatic expansion of the solar wind alone. The angle dependencies suggest that perpendicular heating in Alfvénic wind may be responsible. We quantify the occurrence rate of the two instabilities as a function of the length of unstable intervals as they are convected over the spacecraft. This analysis indicates that mirror-mode and oblique firehose instabilities require a spatial interval of length greater than 2–3 unstable wavelengths in order to relax the plasma into a marginally stable state and thus closer to thermodynamic equilibrium in the solar wind. Our analysis suggests that the conditions for these instabilities to act effectively vary locally on scales much shorter than the correlation length of solar wind turbulence.

Published: December 2022

Three new species of Helminthosporium, H. nabanhensis, H. sinensis and H. yunnanensis collected on dead branches of unidentified plants in Xishuangbanna, China, were proposed by morphological and molecular phylogenetic analysis. Phylogenetic analysis of the combined data of ITS-SSU-LSU-TEF1-RPB2 sequences was performed using Maximum-Likelihood and Bayesian Inference, although H. nabanhensis and H. sinensis lack the RPB2 sequences. Both molecular analyses and morphological data supported H. nabanhensis, H. sinensis and H. yunnanensis as three independent taxa within the Massarinaceae.

Ohlson's Model as a Tool to Predict Performance: A Comparative Study between Commercial Bank of Ceylon PLC and Banking Industry
Authors: Niresh J.A. , Balaputhiran S.
Published: December 2022

The Banking Industry provides a substantial contribution to the Sri Lankan economy. This research aims to compare the forecast performance indicators of the Commercial Bank of Ceylon PLC with the Banking industry. The researcher has selected the Commercial Bank of Ceylon PLC as a sample since it is ranked 1st in the Banking Sector on Colombo Stock Exchange and the only Sri Lankan bank to be ranked for the 10th consecutive year by "The Banker". In this study, the researcher has used statistical software named R to analyze the data considering Profitability, Liquidity, and Capital Adequacy indicators. Data has been gathered over ten years from 2009 to 2018, and the predictions were made adopting Ohlson's Forecasting Model for the subsequent years 2019 and 2020. The Commercial Bank PLC is on track with the industry norms except in areas, especially Net Interest Margin, Liquidity, and Core Capital Ratio, where significant improvements are needed to bring their performance on track, the findings reveal. The Ohlson model's robustness was tested using Mean Absolute Percentage Error (MAPE). It confirms that the model best fits the two variables used in the study named Core Capital Ratio and Total Capital Ratio.
Petrography of bedrock and ice-rafted granules: Flemish Cap, offshore Newfoundland and Labrador
Authors: Pe-Piper G , Piper D J

Published: December 2022

This Open File report provides petrographic information from a scanning electron microscope study of granules and small pebbles in four selected trawl samples from Flemish Cap. The mineral composition of the granules was determined by energy dispersive
spectroscopy (EDS) and textures are shown in backscattered electron images (BSE). It complements Open File 8359 on the heavy mineral assemblage on Flemish Cap. Granules on the central shoals appear to be derived from outcropping Avalonian basement; those to the east and west are predominantly
ice-rafted in origin. These data improve our understanding of the source of the voluminous sands on Flemish Cap and the characteristics of the Avalonian basement rocks on southern Flemish Cap.
Comparative pXRF and Lab ICP-ES/MS methods for mineral resource assessment, Northwest Territories
Authors: Knight R D , Kjarsgaard B A
Published: December 2022

The Geological Survey of Canada undertook a mineral resource assessment for a proposed national park in northern Canada (~ 33,500 km2) spanning the transition from boreal forest to barren lands tundra. Bedrock geology of this region is complex and includes
the Archean Slave Craton, the Archean and Paleoproterozoic Rae domain of the Churchill Province, the Paleoproterozoic Thelon and Taltson magmatic-tectonic zones, and the Paleoproterozoic East Arm sedimentary basin. The area has variable mineral potential for lode gold, kimberlite-hosted diamonds,
VMS, vein uranium and copper, SEDEX, as well as other deposit types. A comparison of analytical methods was carried out after processing the field collected samples to acquire both the < 2 mm and for the < 0.063 mm size fractions for 241 surficial sediment (till) samples,
collected using a 10 x 10 km grid. Analytical methods comprised: 1) aqua regia followed by ICP-MS analysis, 2) 4-acid hot dissolution followed by ICP-ES/MS analysis, 3) lithium metaborate/tetraborate fusion methods followed by ICP-ES for major elements and ICP-MS for trace elements and, 4) portable
XRF on dried, non-sieved sediment samples subjected to a granular segregation processing technique (to produce a clay-silt proxy) for seventeen elements (Ba, Ca, Cr, Cu, Fe, K, Mn, Ni, Pb, Rb, Sr, Th, Ti, U, V, Zn, and Zr) Results indicate that pXRF data do not replicate exactly the laboratory
4-acid and fusion data (in terms of precision and accuracy), but the relationship between the datasets is systematic as displayed in x-y scattergrams. Interpolated single element plots indicate that till samples with anomalies of high and low pXRF concentration levels are synonymous with high and
low laboratory-based analytical concentration levels, respectively. The pXRF interpolations thus illustrate the regional geochemical trends, and most importantly, the significant geochemical anomalies in the surficial samples. These results indicate that pXRF spectrometry for a subset of elements is
comparable to traditional laboratory methods. pXRF spectrometry also provides the benefit of rapid analysis and data acquisition that has a direct influence on real time sampling designs. This information facilitates efficient and cost-effective field projects (i.e. where used to identify regions of
interest for high density sampling), and to prioritize samples to be analyzed using traditional geochemical methods. These tactics should increase the efficiency and success of a mineral exploration and/or environmental sampling programs.

Authors: Mowafi Marwa M. , Elbeialy Marwa A. K. , Abusinna Rasha Gamal
Published: December 2022

Background: Respiratory mechanics are often significantly altered in morbidly obese patients and magnesium sulfate (MgSO4) is a promising agent for managing several respiratory disorders. This study aimed to examine the effects of MgSO4 infusions on arterial oxygenation and lung mechanics in patients with morbid obesity undergoing laparoscopic bariatric surgery. Methods: Forty patients with morbid obesity aged 21–60 years scheduled for laparoscopic bariatric surgery under general anesthesia were randomly allocated to either the control (normal saline infusion) or MgSO4 group (30 mg/kg lean body weight [LBW] of 10% MgSO4 in 100 ml normal saline intravenously over 30 min as a loading dose, followed by 10 mg/kg LBW/h for 90 min). The primary outcome was intraoperative arterial oxygenation (ΔPaO2/FiO2). Secondary outcomes included intraoperative static and dynamic compliance, dead space, and hemodynamic parameters. Results: At 90 min intraoperatively, the Δ PaO2/FiO2 ratio and the Δ dynamic lung compliance were statistically significantly higher in the MgSO4 group (mean ± SE: 16.1 ± 1.0, 95% CI [14.1, 18.1] and 8.4 ± 0.5 ml/cmH2O, 95% CI [7.4, 9.4]), respectively), and the Δ dead space (%) was statistically significantly lower in the MgSO4 group (mean ± SE: −8.0 ± 0.3%, 95% CI [−8.6, −7.4]) (P < 0.001). No significant differences in static compliance were observed.Conclusions: Although MgSO4 significantly preserved arterial oxygenation and maintained dynamic lung compliance and dead space in patients with morbid obesity, the clinical relevance is minimal. This study failed to adequately reflect the clinical importance of these results.

Current status and future prospects of multi-antigen tick vaccine
Authors: Parthasarathi B C , Kumar Binod , Ghosh Srikant
Published: December 2022

Ticks are blood sucking ectoparasite that transmit several pathogens to humans and animals. Tick management focusing on use of chemicals has several drawbacks including development of multi-acaricide resistant tick populations. To minimize the use of chemicals on animals and on the environment, immunization of natural hosts is considered a viable component of Integrated Tick Management System. Most of the tick vaccine trials are focused on single antigen immunization directed against homologous challenge. From commercial point of view, vaccination against one given tick species is not a feasible option. In this context, multi-antigen vaccines comprising of candidate antigens of multiple tick species or both ticks and tick-borne pathogens have commercial potential. Different strategies are considered for the development of multi-antigen tick and/or tick-borne pathogen vaccines. Further, the efficacy of vaccine can be improved by adopting the ‘omics’ tools and techniques in selection of novel antigens and efficient delivery like Lipid Nano Particle (LNP)-mRNA vaccines, viral vector vaccine, live vector vaccine etc. into the host. The subject has been reviewed to address the current status of multi antigen tick vaccines and formulations of the future strategies for the control of TTBDs of human and animals.
A review of public health important fleas (Insecta, Siphonaptera) and flea-borne diseases in India
Authors: Rajamannar V , Govindarajan R , Kumar Ashwani , Samuel Philip P
Published: December 2022

Fleas (Insecta, Siphonaptera) are important vectors of plague and murine typhus in many parts of the world. Currently, about 2700 flea species were described in the world. The most common vector flea Xenopsylla cheopis is found throughout India, but X. astia, and X. brasiliensis are found less and limited in distribution associated with the domestic rats such as Rattus rattus, R. norvegicus, Mus musculus, and Bandicota bengalensis. Bubonic plague is a major flea-borne disease caused by the bacterial pathogen Yersinia pestis, transmitted from rats to humans via the rodent flea, X. cheopis. A major outbreak of plague and high mortality occurred in India. After 1966 with the 3 decadal intervals, plague cases occurred only during the year 1994 reported in 5 different states (Gujarat, Maharashtra, Karnataka, Uttar Pradesh, Madhya Pradesh and New Delhi and subsequently plague cases occurred during 2002 and 2004 after the one-decade interval in Himachal Pradesh (2002). Another outbreak of bubonic plague was reported in Dangud village, Barkhot tehsil, Uttarkashi district, Uttarakhand during October 2004. Ctenocephalides fleas are common in cats and dogs, which are the main vectors of bacteria rickettsiae, such as Rickettsia typhi, R. felis, R. conorii, and Bartonella henselae. Molecular and serological evidence also confirms the presence of R. typhi, R. conorii R. felis and B. henselae pathogens in cats and other fleas in India. Flea bites and flea-borne dermatitis are common in men and pet animals. Because of the re-emergence of the plague, updated information on fleas and flea-borne diseases are essential to control the flea vectors and flea-borne diseases in India. Hence, this comprehensive review updates the available information on fleas and fleas transmitted diseases in India.

The recently described Triatoma huehuetenanguensis, has been reported in Mexico, Guatemala, Belize and Honduras. In Mexico, the species has been collected primarily in rural areas; it has the potential to colonize human dwellings, however, its contribution to Chagas outbreaks remains unclear. In 2021, T. huehuetenanguensis was first observed at Tuxtla Gutierrez city, Chiapas; then a collection for the species was performed. A total of 308 houses were inspected in the intra and peridomestic structures. Only 3 houses (0.97%) were infested. Triatoma huehuetenangensis was the only triatomine specie recorded and four males were collected. None of the bugs tested positive for Trypanosoma infection. We do not have evidence to suggest that urban human-vector contact still limited, and a possible domestication process is possible. The presence of reservoirs, the vector species and the parasite demonstrate that Tuxtla Gutierrez could be at risk of a Chagas disease outbreak.

Published: December 2022

Malaria and typhoid co-infections can be a serious public health issue in tropical countries leading to incorrect diagnosis due to overlapping clinical presentations of malaria and typhoid and hence, causing a delay in implementing the appropriate treatment regimen for these concurrent infections. This study reports a case of six-year-old female child co-infected with severe malaria (Plasmodium falciparum) and typhoid (Salmonella typhi) diagnosed by rapid malaria antigen test (RMAT) and blood culture respectively. Further, analysis of the chloroquine resistance gene Pfcrt for the falciparum demonstrated the presence of K76T mutant allele in pfcrt gene with high IC50 (150nM) for chloroquine (CQ) drug. The present case highlights the significance of timely identification and treatment of co-infections and also provides information about the circulating P. falciparum clinical strains.
Specular microscopic changes of corneal endothelial cells after phacoemulsification in patients with pseudoexfoliation
Authors: Yousef Hassan S. , Amer Ibrahim , Thabet Shymaa A.A.
Published: December 2022

Background and aim

Pseudoexfoliation (PEX) syndrome is an age-related ocular disorder that is known to be linked with early development of cataract. Phacoemulsification, a cataract surgery, is thought to carry higher risk of complication in patients with PEX. This study aimed to evaluate the corneal endothelial cell changes before and after phacoemulsification in pseudoexfoliative patients relative to healthy adults.

Patients and methods

In total, 100 eyes of 100 patients were enrolled in this prospective nonrandomized study who were divided into two groups (PEX and non-PEX patients). All participants were subjected to ocular examination with specular microscopy before and after phacoemulsification. Data for corneal endothelial cell density (ECD), coefficient of variation (CV), and hexagonal cells were recorded before operation and at 1 week, 1 month, and 6 months postoperative.

Results

No significant difference was detected between the two studied groups regarding ECD, CV, and hexagonality either preoperatively or postoperatively at 1 week, 1 month, and 6 months. However, a significant difference between preoperative and postoperative data of ECD, CV, and hexagonality was detected in each group.

Conclusion

Despite the previous conviction that phacoemulsification surgery carries more risks in eyes with PEX, the results of this study prove that phacoemulsification is a safe choice in these eyes without a higher rate of postoperative complications.

Optical coherence tomography changes in Egyptian patients with major depressive disorder
Authors: ElShaarawi Mostafa S. , Gaafar Ayman A. , Shalaby Hisham S. , Abdelgawad Randa H.A.
Published: December 2022

Background

Brain imaging of patients with major depressive disorder (MDD) shows evidence of neurodegeneration and inflammation. The retina is believed to be a prolongation of the central nervous system, and therefore optical coherence tomography readings may give an insight into the pathogenesis of MDD.

Patients and methods

An observational controlled cross-sectional study was performed at Ain Shams University Hospitals from September 2018 to December 2019. Optical coherence tomography was used to compare a group of 30 patients with MDD with a control group of 28 healthy individuals. Measurements recorded were macular thickness, peripapillary retinal nerve fiber layer (RNFL) thickness, and ganglion cell-inner plexiform layer complex (GC-IP) thickness.

Results

Patients with MDD demonstrated significant macular thinning in all zones of the ETDRS map except the central zone bilaterally, and the inner nasal and inner lower zones in right eye. The peripapillary RNFL thickness of patients with MDD revealed significant thinning in the superior quadrant of both eyes. The GC-IP complex of patients with MDD showed significant thinning in the whole temporal and inner lower nasal subzones of the right eye and the upper nasal and lower temporal subfields of the left eye.

Conclusion

Patients with MDD showed reduced thickness of the macula, RNFL, and GC-IP. This may indicate that MDD involves an element of neurodegeneration, such as evidenced in gray matter changes.
