Published: April 2023

ABSTRACT Objective: To identify and summarize the possible associations between screen time and low back pain in children and adolescents. Data source: Systematic searches were performed in five electronic databases (Lilacs, Scielo, Scopus, PubMed and Web of Science) on 01/25/2021, complemented by manual searches in reference lists and on Google Scholar, looking for original scientific articles that included Brazilian observational studies; whose samples had children and/or adolescents aged between 6 and 19 years, without specific clinical conditions, and that presented analyses of associations between indicators of screen time and nonspecific low back pain, based on regression models. Data synthesis: Nine cross-sectional studies whose samples had adolescents were included. Of the 18 analyses identified, nine reported risk relationships between the variables of interest. More specifically, risk associations were found in two studies that evaluated adolescents exposed to at least three hours using cell phone or tablet, and watching television per day. Also, instruments, cut-off points adopted, and screen equipment evaluated were diverse. Conclusions: Even though most of the risk associations were borderline from the statistical point of view, we found a higher frequency of risk associations between screen time and non-specific low back pain in adolescents exposed to screen time for at least three hours a day. In addition, further longitudinal studies with samples composed of children should be conducted across the country.

Abstract Objective: The aim of this study was to characterize child sexual abuse and investigate the factors related to its repetition in the state of Santa Catarina, Brazil. Methods: This is a descriptive and analytical study, with data from 2009-2019 SINAN. Sociodemographic variables related to the circumstances of violence were analyzed. Multivariate logistic regression was used to test factors related to repetitive violence. Results: A total of 3489 cases of child sexual abuse were reported: 73.3% were girls, the most prevalent age ranged from 6 to 10 years, and 51% reported repetitive violence. The majority was perpetrated by one (85.6%) person, and in cases in which two or more perpetrators were involved, the proportion of occurrence was higher for boys (17%) versus girls (13%). Among the risk factors for the repetition of sexual violence are the place of occurrence being the residence, the perpetrator (the stepfather, the brother, and the father) being under the influence of alcohol, and the age of the child between 6 and 10 years. Conclusion: The profile and factors that help in the identification of repetitive child sexual abuse were presented, such as the authorship being related to stepfathers, parents, and siblings, the perpetrator being under the influence of alcohol, and the victim’s age between 6 and 10 years.

Published: April 2023

ABSTRACT Barbados gooseberry (BGB) is a non-conventional vegetable highlighted for its nutritional value, particularly its protein content. However, there is a lack of scientific information for improving the plantation system of this plant. This research proposed to evaluate high-density systems to cultivate BGB plants for sprout production. The experiment was carried out in the Horticulture Sector of the Canguiri Experimental Station Farm from UFPR, located in the county of Pinhais, Paraná State, Brazil. BGB was planted in open field beds using distinctive plantation systems according to plant stands and pruning and thinning management. The experimental design was randomized blocks with three repetitions per treatment. Five high-density plantation systems (treatments) were tested: 10 (10?10): 10 × 10 cm; 2) (20?20): 20 × 20 cm; and 3) (30?30): 30 × 30 cm spacing with thinning to keep one sprout growing per primary branch per plant; 4) (30?30TS) was represented by 30 × 30 cm spacing with thinning to keep one sprout growing from each of two secondary branches grown from the primary branch to give two sprouts (TS) per plant; 5) (30?30FS) consisted of plants with 30 × 30 cm spacing with no thinning (FS = free growing sprouts). The first three treatments were thinned to one sprout per plant. Protein content of BGB sprouts was also determined to verify its real protein content. A high-density plantation system promoted BGB sprouts productivity with high protein content (28.8% from leaves of sprout). Treatment 5 produced the highest yield (21.7 t/ha per month).

Accessibility as the determinant of attending educational opportunities in rural India
Authors: Singh Shivendu Shekhar , Sarkar Basudatta
Published: April 2023

Physical access to education is a major issue of deliberation among governments, transport planners and policymakers. The status of physical access to educational institutes in the region is determined by the collective characteristics of the area, such as proximity and the level of services available. Transport accessibility in rural areas is challenging and affects the physical access to education in developing countries. Subsequently, a research enquiry is posed: does transport accessibility in the region affects access to educational opportunities in the rural context? If yes, what transport-related determinants influence access to educational opportunities? Census data is used for analysis, employing a multivariate regression approach using ordinary least squares estimation. The key revelations of the research are (a) proximity to the educational institute and transit are the critical determinants of attending the educational institute in rural India, (b) bicycle ownership improves attendance at educational institutes in the study region and (c) a considerable gender differential and the rural–urban gap in attending the higher educational institutes exist, signifying the accessibility poverty in the region. This study contributes a framework for analysing the transport accessibility determinants of attending educational opportunities in data-scarce conditions in the global south.

Published: April 2023

This study was carried out to determine the effects of different growing media (peat + perlite, cocopeat, hazelnut husk, rock wool) and different humic acid doses (2, 4, and 8 ml L-1) on tomato plant growth. The performance of the seedlings from planting to fruit set was evaluated to determine the growth of the tomato plant. For this purpose; stem diameter (mm), plant height (cm), leaf number, first flowering, first fruit set, total plant dry weight (g), root volume (m3), and relative growth rate (g cm-2 days-1) parameters were examined. According to the results, the highest stem diameter of 15 mm was obtained in the hazelnut husk media at a dose of 4 ml L-1 of humic acid. As a result, while the best root growth was obtained at 2 ml L-1 humic acid doses in peat-perlite media, the fastest growth and N (3.33%), P (0.58%) and K (3.91%) content were obtained at 8 ml L-1 humic acid doses in cocopeat media. The best leafing, flowering and fruit set were obtained in hazelnut husk media with 2 ml L-1 humic acid doses. As a result, the highest relative growth rate (0.064 g cm-2 days-1) was determined at 8 ml L-1 doses of humic acid applied in the cocopeat media.

Authors:   Department of Health Science, Faculty of Medicine, Lund University, Margaretavägen1B, 22240,  Lund, Sweden., Yasmeen. Naba
Published: April 2023

Background: Neck pain is a public health issue and the world's fourth-biggest cause of disability. Office workers are more affected by poor posture and different weight loads on the neck leading to the development of neck pain. FixaSpine is a wearable device allowing proper sitting or standing posture when using the computer. McKenzie exercises are inter alia used for decreasing neck pain, there are no studies on the combination of FixaSpine and McKenzie exercises. Objective: to evaluate the change in perceived neck pain before and after the combination of training with FixaSpine and performing McKenzie exercises among office workers in comparison to postural text reminders. Materials and methodology: a pre-post-interventional pilot study was carried out in Southern Sweden with 39 participants. The intervention group received training with FixaSpine and McKenzie exercises and the control group received postural text reminders for the duration of four weeks. The participants performed five days a week during working hours. The data was collected by Neck Pain and Disability Scale. Paired samples t-test and independent t-test were used for analysis. Results: a total of 39 participants (intervention group (n = 25) and control group (n = 14)) were included in the study. The intervention group showed a statistically significant difference in neck pain (p = 0.000) and in the control group, there was no significant difference in neck pain (p = 0.57). There was a significant difference in post-total NPDS scores across the groups (p = 0.002). The magnitude of the mean differences was very large (mean difference = -26.21, 95 % confidence interval: -42.12 to -10.3; Glass’delta = 1.23). Conclusion: There was a significant decrease in perceived neck pain measured before and after an intervention by a combination of training with FixaSpine and performing McKenzie exercises among office workers in comparison to postural text reminders. Further research is needed involving control groups (FixaSpine /McKenzie exercises). KEYWORDS: FixaSpine, McKenzie exercises, Neck load, Neck pain, Office workers, Posture.
Une chaine de violences par temps de Covid : du travail au mal-être, du soin à l’enfermement.

Published: April 2023

Durant la crise sanitaire de 2020, les bouleversements liés aux mesures de confinement, à la reprogrammation des activités et aux mesures d’hygiène et de sécurité ont bouleversé les routines de travail des établissements sanitaires et médico-sociaux en France. Le souci de la santé mentale des professionnels travaillant dans ces structures, dans ce contexte, a rapidement attiré l’attention aussi bien des institutions de soin et des professionnels de santé mental que celle des autorités. Le cas des Établissements d’Hébergement pour Personnes Âgées Dépendantes (EHPAD), peu étudié, constitue un objet privilégié pour saisir les enjeux rencontrés durant cette période et leurs éventuels retentissements en termes de santé psychologique. Au sein de ces établissements, en effet, où le spectre de l’institution totale constitue un enjeu propre pour les professionnels, une chaine de violences aussi bien organisationnelles et institutionnelles que physiques est susceptible de s’être organisée. Il y a là un moment de tensions d’abord structurées par le genre, autant en ce qui concerne celles qui effectuent le travail dans ces établissements – et qui doivent arbitrer entre des valeurs, des normes et des pratiques particulièrement difficiles en temps de crise — qu’en ce qui concerne les personnes qui reçoivent ces prestations. Fondés sur une enquête qualitative par entretien de recherche, les résultats que nous présentons ici proposent précisément de discuter comment la ségrégation professionnelle dans le secteur médico-sociale implique des formes de souffrance structurées par des normes professionnelles affectant d’abord les femmes de milieu populaire, et susceptibles de retentir également sur des populations prises en soin également fortement féminisées.

Body contouring surgery enhances physical appearance by means of surgical subcutaneous fat removal (SSFR). However, it remains unclear how SSFR may affect glucose metabolism and its broader effects on the endocrine system, especially in individuals who have undergone obesity (bariatric) surgery. This study aimed to evaluate the impact of SSFR on glucose excursion and insulin resistance in such patients, by examining them over three visits (within 1 week before surgery, 1 week after surgery and 6 weeks after surgery). The independent impact of SSFR and history of obesity surgery on glucose homeostasis was evaluated in twenty-nine participants, of whom ten patients (34%) had a history of obesity surgery. Indices of glucose metabolism were evaluated using cluster robust-error logistic regression. Results indicated that SSFR led to a gross improvement in insulin resistance at 6-weeks after the surgery in all patient’s irrespective of BMI, type 2 diabetes mellitus (T2D) status or history of obesity surgery (OR 0.22; P=0.042). However, no effect was observed on glucose excursion except for a transient increase at visit 2 (1 week after surgery) in those without prior obesity surgery. Interestingly, participants with a history of obesity surgery had approximately half the odds being in the upper tertile for HOMA-IR (OR 0.44; p=0.142) and ten-folds lower odds of having severely abnormal glucose excursion (OR 0.09; p=0.031), irrespective of their BMI, T2D status, or time post SSFR. In conclusion, this study showed that body contouring surgery through SSFR resulted in (at least) short-term improvement in insulin resistance (independent of the participant’s BMI, T2D status or history of obesity surgery) without affecting glucose excursion under the GTT. On the contrary, obesity surgery may have a long-term effect on glucose excursion, possibly due to sustained improvement of pancreatic β-cell function.
REPRESENTATIVE BUREAUCRACY AND INCLUSION: CITIZEN PARTICIPATION OF ETHNIC MINORITIES IN VIETNAM
Authors:   Vietnam National University, Hue Trinh Hoang Hong
Published: April 2023

In the context of Vietnam, with fifty-four ethnic minority groups and sixty-three provinces/municipalities, this study aims to fill a gap in the literature by looking at ethnic representation and its influence on citizen participation at the local level based on Representative Bureaucracy and Inclusion theory. We use the combination of three datasets the Public Administration Performance Index (PAPI), the Committee for Ethnic Minorities Affair, and the General Statistics Office of 63 provinces in Vietnam from 2012 to 2017. We run a panel data analysis random-effects model (REM) with White-Huber standard errors to correct heteroskedasticity in current years to estimate the effects. Findings support the research hypothesis that ethnic minority groups in Vietnam are negatively associated with citizen participation in the local government, particularly in civic knowledge. Additionally, the level of citizen participation is also negatively related to the urbanization, unemployment, and poverty rates of each province. However, it is positively associated with the education level of each province's population. With these findings, this study also proposes some policy implications to ensure the development rights of ethnic minorities in Vietnam.

Graphene sand composite (GSC), sand media coated with graphene, possess higher adsorption capacity for wastewater treatment compared to conventional activated carbon (AC). However, large-scale synthesis of GSC due to costly carbonaceous source appears as a great challenge towards commercial application. Palm oil mill effluent (POME), which abundantly discharged from the palm oil industry, appears to be a potentially low cost carbonaceous source for the synthesis of GSC. This study presented a green chemistry approach by utilizing the POME as carbonaceous source coated on the different particle size of river sand in synthesizing POME-based GSC (P-GSC). Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-ray (EDX), and X-ray Diffraction (XRD) analysis indicated the successful graphinization of POME coated onto the river sand surface. Adsorption studies - batch column study and batch equilibrium study showed that small size P-GSC (0.30 – 0.60 mm) had the best performance in removing chemical oxygen demand (COD), colour, turbidity, and total dissolved solids (TDS) from diluted aerobic POME up to 94.7 %, 92.3 %, 83.3 %, and 51.5 %, respectively. This could be attributed to its larger surface area that provides more active sites for adsorption. Equilibrium sorption data of small size P-GSC was well-fitted to the Freundlich model and its associated adsorption kinetic could be described by Pseudo First Order model. The concept of sustainable waste-to-treat-waste has been proven throughout this study, where POME can be utilized to produce high performance P-GSC that can be used to treat aerobic POME.

At present, the development of semiconductor sensor elements that detect hazardous oxides (CO, CO2) is an urgent scientific and technical task. As a rule, wide-gap metal oxides, such as ZnO, CuO, are used as a sensor matrix. Today, there are a large number of approaches to the synthesis and modification of gas-sensitive semiconductors with the possibility of sensitivity to carbon monoxide and carbon dioxide. The state of the environment and the forms of morbidity that occur in this area. The ultimate goal of the study is to find the optimal conditions for the mechanical grinding of zinc oxide in order to achieve the maximum value of the chemoresistive response. In this paper, we studied the patterns of evolution of defects and chemical features of the surface under the action of mechanoactivation in the attritor. Using the X-ray photoelectron spectroscopy (XPS) method, we studied samples ground for 1, 3, and 5 hours using an attritor in an isopropyl alcohol without additional chemical treatment. Deconvolution was carried out by subtracting the Shirley background and then fitting the peak to the Voigt functions, which have a mixed character of Gauss and Lorentz. As a result, it was found that the ratios between the elements and their phases correlate with the stoichiometry of the sample.

Silicon is the main raw material for micro- and nanoelectronics. Achievements in these areas are based to a sufficient extent on knowledge of the processes occurring on the surface. Therefore, the study of these processes on a silicon surface is topical today. In this work, the dependences of the angles of water runoff from the silicon surface on the modes of their preparation are experimentally studied. The objects of study were Si single-crystal silicon wafers with (111) surface orientation. An aqueous solution of hydrofluoric acid was used to clean the surface from contamination and natural oxide. To assess the efficiency of cleaning and the state of the studied solid surfaces, the dynamic wetting angle was measured. Distilled water was used as a wetting liquid. It has been found that plates for which ethanol is used in the preparation procedure are better wetted with water. The obtained experimental data are confirmed by the Auger analysis — the plates treated with ethanol contain a smaller amount of carbon-containing impurities. The obtained surface topograms also indicate the effect of surface chemical treatment on its roughness.
Is it Possible to Realize Consciousness Artificially?
Authors:   Belarusian State University of Informatics and Radioelectronics, Minsk, 220013, Belarus, Abramov I.I.
Published: April 2023

Three identified possible directions for the artificial realization of consciousness are considered: 1) materialistic; 2) idealistic; 3) hybrid. In principle, this is the most difficult task of artificial intelligence. The most promising approaches to the artificial realization of consciousness are distinguished in the directions. As a result of the analysis, a hypothesis was formulated about the possibility of such an implementation. Moreover, this can be, in principle, carried out within the framework of the three directions noted, but approximately. At the same time, if we consider the consciousness of a particular person, then in an artificial analogue, in essence, everything that is stored in the brain of this person should be reproduced, and this is a task offantastic complexity. The author sees a possible solution of the problem by copying information from the corresponding brain. The question of the dynamic change of consciousness as a result of human interaction with the external environment will also be very difficult.
Traditional House of Unprivileged Stratum of Korean Society at the Turn of the XIX–XX Centuries (According to Foreigners)
Authors:   Taras Shevchenko national University of Kyiv, Petrushko Vitalii
Published: April 2023

Until the middle of the 19th century, the world of the Far East was almost unknown to Westerners. Travelers, missionaries, diplomats and writers from Europe and America, exploring the world of the Far East, inevitably came across buildings radically different from European views about architecture. Curved tiled and straw roofs, paper walls and high fences forming a labyrinth of city streets – all this greeted foreigners who visited Korea at the turn of the XIX–XX centuries. On the eve of the annexation of Korea in 1910, states from different parts of the world fought for hegemony over the territory of the peninsula, primarily the Japanese and Russian empires. When the world monarchies fought for influence on the Korean peninsula, elements of Western architecture, such as brick temples, high buildings, asphalt streets, etc., came to Korea. However, the effects of Westernization remained too weak to change the traditional landscape of the Korean city fundamentally in the late Victorian era. Traditional Korean «hanoks» were widespread on the territory of the Korean peninsula from the rise of the Joseon dynasty (end of the XIV century) to the post-war modernization of Korea in the second half of the XX century. We find many descriptions of this type of housing in the works of Western authors of the late XIX and early XX centuries, such as the American writer Louise Jordan Miln, the British researcher Isabella Bird, the American missionary Homer Hulbert, and the Russian Orientalist Dmitriy Pozdneev. In this article, we investigated the hetero image of traditional Korean architecture of the underprivileged part of the Korean population in the works of Western authors at the turn of the XIX–XX centuries. Also, we analyzed the image of traditional Korean architecture through the point of view of travelers from Europe and the USA.

Published: April 2023

Background: Angiotensin converting enzyme (ACE) is the key enzyme, regulates the blood pressure which is encoded by 21kb gene that consists of 26 exons and is located on chromosome 17, contains a polymorphism in the form of either Insertion (I) or Deletion (D). The aim was to study the effect of antihypertensive drugs in patients of essential hypertension associated with ACE gene polymorphism. Methods: Hypertensive patients were recruited followed by genetic test was done for detecting ACE gene polymorphism, then patients were divided as Group-A & B. Group –A and B patients were treated with atenolol (25mg) and azilsartan (40 mg) for three months respectively. Results: Systolic and diastolic blood pressure was recorded in both the groups before and after commencement of treatment. Among 88 patients of newly diagnosed hypertension, majority of study population belongs to genotype D/D (38.63%) followed by I/D (31.81%) and II (29.54%) genotype. Significant difference was found in systolic blood pressure (p<0.05) of both groups but not diastolic blood pressure (p>0.05). Conclusion: The rate of control of blood pressure was high in I/I genotype followed by D/D genotype irrespective of treatment group. Overall better prognosis was observed with azilsartan 40mg compared to atenolol 25mg treatment in patients with ACE gene polymorphisms.

Material and methods: Hospital-based observational study conducted on children between 6 months to 5 years of age, admitted to Government General Hospital, Srikakulam and having anemia according to WHO classification. Results: Of the 157 children diagnosed with anemia over 18 months period, iron deficiency anemia is the commonest cause of anemia, seen in 107 children followed by sickle cell anemia seen in 21 children. Out of the sampled children, 154 children recovered, and 3 children succumbed to death. Conclusion: Nutritional anemia, particularly iron deficiency anemia is the most common type of anemia in 6 months to 5 years-old children. Co-morbidities like malnutrition, parasitic infestations, diarrheal diseases, and recurrent respiratory tract infections form a vicious cycle and result in nutritional anemia. Identifying the factors that are leading to iron deficiency anemia and implementing the control measures like early iron supplementation results in reducing morbidity and mortality.
Theoretical Analysis of Socialism: Mises vs. Brutskus (to the Centenary of thе Publications of Books)
Authors:   Belarusian National Technical University, Kavaliou Aliaksandr V.
Published: April 2023

The article is devoted to the centenary of the publication of books by L. von Mises and B.D. Brutskus dedicated to the criticism of the socialist system. The similarity of the theoretical arguments used by the authors in the analysis of the economic aspects of socialist society makes it possible to call the theorem on the impossibility of socialism the double name of Mises-Bruckus. The authors consider the abolition of the institutions of private property on the means of production, as well as the market as a mechanism for coordination, and entrepreneurship to be the main factor of the rational impossibility of the economic system of socialism. Without these institutions, it is impossible to form a price system as a signaling mechanism about the most efficient directions for the distribution of resources. Without this information, the planning body will not be able to determine the goods that should be produced. Mises' analysis does not focus exclusively on the form of socialism that was realized in Soviet Russia, however it can be applied to any pseudo-socialist system or form of interventionism. Brutskus confirms the theoretical arguments with examples from Soviet practice.

Published: April 2023

Gaining the technological sovereignty is one of the main goals that the Russian Government is pursuing today. Under these conditions, the importance of professionals, who are “specialists of the highest qualification level” as defined by the Federal State Statistics Service of the Russian Federation, is growing. The information about dynamics, composition and specific features of the group of professionals in Russia is becoming more significant as well. However, professionals as a group are now poorly identified. Among the data on professionals available for a researcher, only two credible sources of information can be named – the employment statistics published by the Federal State Statistics Service of the Russian Federation and scientific publications devoted to them, and the date from The Russia Longitudinal Monitoring Survey – Higher School of Economics (RLMS-HSE). Only abovementioned sources provide data in which structure professionals are separately identified. Therefore, we assume that currently available information about professionals is insufficient, contradictory, and partly quite controversial. This is mainly due to methodological and methodical challenges of the definition of the term “professional”. This article analyzes how the term “professional” is defined in Russian science and statistics. The author offers ways to overcome the vagueness associated with the use of the term “professional” by analyzing features of Russian institutional environment. In this article, the main approaches to the interpretation of the concept "professional" in social sciences are determined. The specific features of the classification of the term in the ISCO-08 and All-Russian Classification of Occupations are considered in the article. The solution proposed involves correcting the basic version of ISCO-08 in RLMS-HSE databases. The advantages of an adjusted version of ISCO-08 that can be used in research on socio-professional structure in general and with the focus on professionals are demonstrated in the article. The article also discusses how the share, composition, and characteristic features of the group of professionals change when the approach offered by the author is applied. The multidirectional dynamics in the share of professionals when different versions of ISCO-08 are used is demonstrated on the RLMS-HSE data from 2001–2021, and the conclusion is made about the specifics of the institutional environment in Russia which strongly affects the situation of this professional group.
Implementação da Alfabetização Midiática e Informacional pelo bibliotecário no âmbito das bibliotecas escolares
Authors: Valladares de Oliveira Soares Laura , Fortes Luce Bruno , Brasil Estabel Lizandra
Published: April 2023

O presente estudo aborda a relação entre a Alfabetização Midiática e Informacional (AMI) e sua implementação por meio da atuação dos bibliotecários no âmbito das bibliotecas escolares. No contexto atual, no qual os indivíduos necessitam compreender o universo informacional e desenvolver a capacidade de identificar e reconhecer suas necessidades informacionais para a seleção e uso das diversas fontes de informação e para a qualidade na realização da pesquisa e nos resultados alcançados, a biblioteca escolar torna-se protagonista para que ocorram os processos de aprendizagem e de construção de conhecimento. Diante disto, esta pesquisa tem como objetivo verificar se existem estudos em âmbito nacional que relacionem a AMI e a atuação do bibliotecário que trabalha nas bibliotecas escolares.  Para tal, realizou-se um levantamento bibliográfico das publicações nacionais que abordam esta temática, em bases de dados abertas, até o final de novembro de 2021. Foi realizada a análise de sete publicações recuperadas nesta busca. A partir do resultado da análise dos dados coletados, foi possível perceber que apesar da necessidade de urgência na sua implantação, o tema AMI ainda é pouco explorado pelos pesquisadores brasileiros e a sua relação com bibliotecários e bibliotecas escolares é ainda menor. Além disso, os estudos ressaltaram que ainda há muito para ser feito em relação ao desenvolvimento de competências informacionais, mas evidenciaram a necessidade da presença e da atuação do bibliotecário, ressaltando o quão imprescindível é o protagonismo deste profissional no contexto educacional e informacional na escola, nos diferentes tipos de bibliotecas e na sociedade.
Perspective study of disorders of thought, language and communication in schizophrenic patients of Maharashtra
Authors: Ambekar Prakash
Published: April 2023

Schizophrenia is a mental disorder characterised by paranoid, hallucination and delirium. The person with such disorder cannot lead a normal life in the society due to his abnormal communication and thought disorder. Hence such disorders are helpful to diagnose the type and severity of disease.

Out of 1000 (one thousand) patients 500 were acute schizophrenia and 500 were chronic schizophrenics. Among 1000, 330 were paranoid and 670 were non-paranoid. The disorder of FTD, language, communication disorders in acute, chronic non-paranoid and paranoid schizophrenia were noted.

In the comparison of acute and chronic schizophrenic patients – Negative FTD scores positive negative FTD scores, language disorders score was highly significant (p<0.001). In the schizophrenic negative FTD score Negative positive FTD scores, thought disorder score, language disorder scores were highly significant (p<0.001).

This study will be helpful to psychiatrist to differentiate acute and chronic schizophrenic patients and treat them efficiently with proper medication so that such patients can lead normal social and family life.

: Iron deficiency anaemia (IDA) is often associated with congenital heart defect (CHD) in children, especially in developing world. Often it remains undiagnosed due to the unaffordability to do costly tests like serum ferritin. We have done this study to know whether simple test like complete hemogram is sufficient to diagnose IDA in a child with CHD.

This hospital based observational study was done for a period of one and half year in paediatric ward of a district medical college of eastern India in children up to the age of 12 years with echocardiography confirmed CHD. Blood sample were tested for serum ferritin, mean corpuscular volume (MCV), mean corpuscular hemoglobin and hemoglobin concentration (MCH,MCHC) and red cell distribution width (RDW) to diagnose IDA.

: We found IDA in 46 children out of total 100 CHD cases based on serum ferritin level. Out of 46 IDA children, 40 children (87%) had low MCV, 39 children(84.8%) had low MCH, 33 children (71.7%) had low MCHC, 41 children (89.1%) had high RDW and 37children(80.4%) having microcytic hypochromic picture. In logistic regression analysis we found RDW as the independent predictor of IDA.

: IDA is fairly common among children with CHD. Simple blood tests of complete hemogram including MCV, MCH, MCHC and RDW can diagnose it effectively where RDW shows the most predictive value in our study. So in resource limited developing countries we may not depend on costly gold standard tests like serum ferritin to diagnose IDA.

Lev Karsavin on the Religious Meaning of Bolshevism and Russian Revolution
Authors: Kara-Murza Alexey
Published: April 2023

The article examines the unique role of the Russian émigré intellectual Lev Platonovich Karsavin (1882–1952) in understanding “Russian communism” as a phenomenon of a deep religious nature. It is noted that the young Karsavin was formed as a historian, a specialist in the history of European religiosity, medieval sects and heresies, various forms of interweaving between religion and politics. This experience of specific historical and cultural research helped Karsavin, who became an active figure in Russian Orthodoxy during the First World War, in analyzing the origins of the Russian revolution and Bolshevism. Having found himself in exile in 1922, Karsavin continued to actively develop the theme of the “religious” nature of Russian Bolshevism, believing that only along this path would it be possible in the future to overcome it from the standpoint of Orthodox Christianity.
