Published: September 2022

(1) Background: Spontaneous intracerebral haemorrhage (ICH) accounts for approximately 15% of all strokes and is a leading cause of disability, with a one-month mortality rate of 40%. Whereas factors predicting short-term mortality are well known, data regarding long-term outcome are scarce and imprecise. Only a few studies revealed association of serum calcium level with outcome of stroke particularly ischaemic stroke but data regarding intracerebral hemorrhage is very limited. Therefore, to reveal the short-term hospital outcome of intracerebral hemorrhage patient on the basis of admission serum calcium level is the objective of the study. Methods: This study was a hospital based observational study and conducted at the Department of Neurology, Neurosurgery and Medicine in Dhaka Medical College Hospital. People who were suffering from intracerebral haemorrhage and were admitted in the department of Neurology, Neurosurgery and Medicine were approached for inclusion in the study according to inclusion and exclusion criteria. Ethical issues were ensured properly. After written informed consent history and physical examination were done. Diagnosis was confirmed by researcher with the aid of CT scan. Total 365 consecutive samples were collected and incompletion of data was considered exclusion of the study.

In Sub-Saharan Africa, the amount of household waste is expected to increase due to population growth and rapid urbanization. In addition to their impact on human and animal health, it has been proven that these wastes strongly contribute to global warming. Their management is nowadays a major concern in cities and countryside. The study was carried out to evaluate the prospects for the valorization of green kitchen waste in animal feed. A system for separating green kitchen waste from other household waste was set up in about thirty households in the commune V of Bamako. After the installation of the trash cans, weekly visits were made to the households to characterize the contents of the trash cans before weighing them. The results show a strong variability in the production of green kitchen waste according to the socio-professional category of the household head. The weekly production of this waste is between 0.46 and 1.90 kg for households of 2 to 16 people. The bromatological analysis carried out on a mixed sample shows that they constitute a potential feed resource for urban and peri-urban livestock with feed values that are between those of forage and oilcake. The valorization of these sub-products in livestock feed could contribute to the sanitation of our neighborhoods but also to the reduction of methane emissions in municipal dump sites.
How to determine the prognosis of renal function in CKD?
Authors: Gozhenko A. I. , Ivanov D. D.
Published: September 2022

The presented material raises the most important question in practical nephrology – how to correctly assess kidney function to understand the prognosis and duration of the predialysis period in a particular patient with chronic kidney disease (CKD)? From the standpoint of onto- and phylogenesis, the hierarchy of kidney functions was assessed. It is noted that the existing approaches to such an assessment are convenient for practice, but do not sufficiently take into account individual characteristics and are devoid of a load component that can show kidney reserves. The authors focused on the functional renal reserve (FRR) and the possibility of its detection. The above technique with 0.45 % saline allows revealing the true functional capabilities of the kidneys and understanding the patient's capabilities in the pre-dialysis period. Conclusions are drawn about the convenient use of the KDIGO scale, a more individual approach when using the QxMD calculator, and the possibility of a personalized approach when assessing the FRR.

Introdução: A imunossupressão pode ser um risco para o aparecimento de lesões por pressão pois o iminente emagrecimento desses pacientes deixa bem evidentes as proeminências ósseas facilitando a constante pressão nestes locais. Objetivos: Descrever as condutas assistenciais e preventivas de enfermagem frente a pacientes com doenças infectocontagiosas e parasitárias portadores de lesões por pressão. Metodologia: Trata-se de uma pesquisa retrospectiva de caráter descritivo com abordagem quantitativa onde as variáveis utilizadas foram obtidas a partir de informações secundárias existentes no banco de dados da comissão de curativos de um hospital referência em infectologia. Resultados: Foram analisados registros de 25 pacientes com lesões por pressão, destes, 96% eram pacientes acamados e a maioria apresentavam lesões por pressão infectadas. Quanto ao perfil epidemiológico observou-se que o gênero masculino foi o mais acometido (84%), tendo como patologia de base aquela causada pelo Vírus da Imunodeficiência Humana (92%). Das condições socioeconômicas observou-se que 48% deles não tinham nenhuma renda. Quanto aos aspectos nutricionais, 76% eram emagrecidos e com baixo peso. Quanto à classificação das lesões, 42,9% eram três. As condutas terapêuticas de enfermagem mais evidentes nos registros foram: a limpeza dos ferimentos com soros fisiológicos a 0,9% e glicosado a 0,5% mornos (para limpar, hidratar e facilitar o crescimento de células neófitas), também o emprego de desbridantes autolíticos. Quanto às ações para profilaxia, a utilização das determinações existentes nas variáveis da escala de Braden foram as mais utilizadas. Conclusão: Ainda há a necessidade de sensibilização do corpo de enfermagem quanto ao compromisso em aplicar todas as determinações já existentes nas normativas do Ministério da Saúde-MS para benefícios destes pacientes acamados no que diz respeito à prevenção de lesões preveníveis, principalmente os que têm perda de tecido adiposo em grandes proporções em virtude da imunossupressão.

Aim Non-operative treatment approach is another method used in the treatment of uncomplicated appendicitis, in which the infection in the appendix is suppressed and treated with antibiotics. Our study aims to investigate the clinical outcomes and the risk factors for recurrence in our pediatric patients with suspected uncomplicated appendicitis, who underwent non-operative treatment. Methods The medical data of the patients who underwent non-operative treatment with the diagnosis of suspected uncomplicated appendicitis between January 2016 and January 2021 in a tertiary pediatric surgery center were analyzed. Demographic data, treatment process, and clinical results of the patients were recorded. Statistical evaluation was made by comparing the two groups with and without recurrence after non-operative treatment. Results The median age of 41 patients whose data were evaluated was 13 (6-17) years. Eight patients (19.5%) had appendicolith. The median duration of IV antibiotic treatment was 4 (3-7) days, and the patients' abdominal tenderness disappeared in a median of 2 (1-4) days. Recurrence developed in 8 (19.5%) patients after a median of 7 (1-14) months after non-operative treatment. It was found that the time to the disappearance of abdominal tenderness was statistically longer in the group that developed recurrence than that in the group that did not (p=0.01). Conclusion Our study revealed that appendicolith was not a risk factor for the development of recurrence. The time to the disappearance of abdominal tenderness may be useful for detecting patients at a higher risk of recurrence.

Authors: Ray Biplob Kumar , Majumdar Angshuman , Gangopadhyay Sankar
Published: September 2022

An Erbium-Doped Fiber Amplifier (EDFA) is an in-line component in modern all –optical telecommunication infrastructure. Different parametric characteristics of an EDFA express the suitability and excellency of performance in its real field application. Intensities of pump and signal vary with distance from the core-axis along the radius of the fiber which is one of the significant characteristics of an EDFA. Change of behavior of pump and signal intensities along the radius of the fiber in an erbium-doped dual-mode trapezoidal index fiber made amplifier due to Kerr nonlinearity phenomenon originating from launching and transmission of intense light from LASER beam inside the amplifier for the LP_11 mode has been exercised in this case. In the present case, some trapezoidal-index fibers of different normalised frequencies have been opted. This exercise is an implementation of the reliable and easy mathematical instrument, the Chebyshev technique. Results derived in this exercise exhibit a fantastic similarity with those derived by the rigorous finite element method. This study with implementation of such a reliable and easy technique may help the interested optical engineers.

Published: September 2022

The aim: To map and compare mental health interventions during the Covid-19 pandemic in China and Western-Europe. The focus was specifically on the availability, duration, target group, content, setting, and outcomes of the interventions.
Materials and methods: A scoping review was conducted by utilising several scientific databases. A total of 479 articles were found after removing the duplicate records. After screening, 36 articles were included in the study. Relevant intervention characteristics were systematically mapped, and compared within and among countries.
Conclusions: All interventions had shared aims to improve the psychological resilience and to reduce psychological distress. In particular, anxiety- and depression-related symptoms were commonly addressed. On average, interventions in China were larger scaled, had longer durations, and often used combinations of strategies such as therapies and exercises both in-person and remotely. Interventions in Western-Europe tend to be locally implemented on a smaller scale, and often used a single strategy. Most Chinese interventions targeted adolescents, while all interventions in Western-Europe were meant for adults. Most interventions were assessed using quantitative methods using various mental health scales, showing statistically significant effects in improving mental health.

The aim: To analyze the levels of competence formation in parents of senior preschoolers with moderate ID and to substantiate the obtained indicators for practical use.
Materials and methods: The sample of the study was 162 persons: experimental group (EG) – parents (or persons substituting them) of 53 preschoolers with moderate ID – 96 persons (out of the total number, 12 children are brought up by mothers without fathers); control group (CG) – parents (or persons substituting them) of 41 preschoolers with MID – 66 persons (out of the total number, 16 children are brought up by mothers without fathers).
Results: The use of Fisher’s φ-criterion allowed to draw the following conclusions: first, at the ascertaining stage of the experiment the characteristics of the EG and CG according to certain indicators of parental competence were homogeneous (α=0.05). At the control stage – significantly different indicators of the experimental group (α=0.01). Secondly, positive changes in the identified characteristics in the EG and absence of such changes in the CG, gives grounds to argue about the effectiveness of implementation of the developed and presented in the experimental model forms, methods and conditions for the development of parental competence.
Conclusions: Thus, despite almost identical indicators of competence levels in parents of the EG and CG at the ascertaining stage of the experiment, the molding stage testified to the specific advantage of representatives of the experimental group over representatives of the control group on levels of development of motivational-personal, gnostic, communicative-activity criteria of competence of parents of children with moderate ID.

The article represents data on adaptation and development of method for chlorophos analysis (active substance of agent «Antiovod») in organs and tissues of calves and cow milk by gas-liquid chromatography method. The method is based on extraction of chlorophos from samples of animal organs, tissues, organs and milk by acetone with addition of 1% acetic acid solution, evaporation of acetone-aqueous extract followed by reextraction into chloroform, chloroform evaporation, dissolution of residue in acetone and analysis of samples using gasliquid chromatography. The sensitivity of the method is 0.005 mg/kg (or mg/l). Residues of chlorophos in tissues and organs of calves were determined on days 5; 10; 15 and 21 post topical treatment with agent «Antiovod». The highest agent concentration was found in the first period of studies, i.e. at day 5. At day 21 post topical application of agent «Antiovod» chlorophos was not detected in any organ of calves. It was found that there was no release of chlorophos with milk in dairy cows treated with agent «Antiovod» at all tested time points, i.e. at days 1; 3; 5 and 10 post application. Based on the obtained data it is recommended to slaughter cattle for meat at day 21 post treatment with «Antiovod». It is recommended to use milk from cows treated with agent «Antiovod» without restrictions.

Há uma permanente ferida na sociedade brasileira que reverbera sua herança colonial e afrodiaspórica. Nas artes visuais e nos seus discursos é possível encontrar e justapor de forma anacrônica diferentes fragmentos que apontam para uma contínua reiteração de elementos que partem de uma pretensa essência do sujeito negro e seu uso como categoria para situar aprodução artística de homens e mulheres racializados. Ao longo dos séculos 19 e 20, ganhavam espaço abordagens que apontavam uma relação entre olhares essencializados e sujeitos racializados, criando a perversa correspondência entre a pertença à raça negra e os critérios de leitura e classificação de objetos que passaram também a ser racializados e, assim, hierarquizados de maneiras análogas àquelas que subalternizaram os corpos negros de homens e mulheres desde a escravização até os dias atuais. Reunindo imagens, trechos de textos referenciais acerca da arte e da cultura brasileira nos séculos 19, 20 e 21 que tomam como tema a produção de negros e negras,este artigo/ensaio apresenta evidências da permanência do  racismo estrutural e aponta para a urgência de pensamentos pautados pelo enfrentamento desses temas nas artes visuais brasileiras.Palavras-chave:Artes visuais brasileiras.

Todos os demônios estão aqui: como a história visual da Revolução Haitiana falseia o sofrimento negro e sua morte / All the devils are here: how the visual history of the Haitian Revolution misrepresents Black suffering and death

Published: September 2022

O ensaio investiga as representações da Revolução Haitiana, sobretudo imagens publicadas em livros e periódicos, que construíram um imaginário colonial da morte e do sofrimento negro, invertendo os termos da dominação racial − como se as maiores vítimas tivessem sido as pessoas brancas. Ao analisar gravuras de ampla circulação, Marlene L. Daut demonstra como  essa construção estética bestializou e deturpou os significados da luta negra por sua própria liberdade. Aponta, por fim, para a importância de artistas contemporâneos que têm buscado retratar o heroísmo e a dor da população negra em contexto no qual permanecem as brutais violações de direitos humanos. Marlene L. Daut é professora de Estudos da Diáspora Africana no Carter G. Woodson Institute e no Programa de Estudos Americanos na Universidade da Virginia. É autora de Baron de Vastey and the origins of black Atlantic humanism (Palgrave, 2017) e Tropics of Haiti: race and the literary history of the Haitian Revolution in the Atlantic world, 1789-1865 (Liverpool, 2015).

Imaginário colonial. AbstractThe essay investigates how representations of the Haitian Revolution, mostly images published in books and magazines, informed a colonial perception of Black death and suffering, by reversing the terms of racial domination − as if the great victims had been White people. By analyzing widespread illustrations, Dr. Marlene L. Daut demonstrates how this aesthetic construction bestialized and misrepresented the Black struggle for their own freedom. Finally, it points out the importance of contemporary artists who have sought to portray the heroism and pain of the Black population in a context in which brutal human rights violations remain.
