Published: July 2024

As bacias hidrográficas são unidades territoriais que promovem o desenvolvimento sustentável. Para isso é necessário o profundo conhecimento do seu relevo e da sua drenagem o que é possível pelo uso da morfometria associada a informações geoespaciais. Nesta perspectiva, o objetivo do presente estudo é avaliar a dinâmica geoespacial, morfométrica e de cobertura da terra visando a compreensão da dinâmica hidrológica da paisagem da Bacia Hidrográfica do Rio Pericumã (BHRP). A caracterização morfométrica foi feita a partir do Modelo Digital de Elevação (MDE) do projeto TOPODATA, a drenagem foi vetorizada e ordenada manualmente com base nas cartas topográficas da Diretoria de Serviço Geográfico do Exército e o MDE. Para a geração dos mapas de uso e cobertura da terra da BHRP, utilizou-se a plataforma do Google Earth Engine para obtenção dos dados do Projeto de Mapeamento Anual de Cobertura e Uso do Solo. A BHRP apresenta drenagem de 6ª ordem, possui formato alongado e padrão dendrítico, que reflete a interação entre clima e geologia. Verificou-se que os usos e cobertura da terra auxiliaram na correlação dos impactos ambientais e as ações antrópicas; a classe de formação florestal foi mais observada em todos os anos analisados, a que mais cresceu foi pastagem, causando alterações extremas no regime hidrológico, associada à maior declividade, pode conduzir à maior velocidade de escoamento. Logo, a crescente expansão de pastagens exerce pressão sobre a vegetação e os recursos hídricos, é importante ter dados para auxiliar na gestão de controle e recuperação dos locais suscetíveis à degradação.
Emergency repairs downstream of earth and rockfill dams with water spring with indication of internal erosion
Authors: Barreto Marcelo , Helder Cardoso Teixeira Sidnei
Published: July 2024

During periodic dam safety assessments, various anomalies are identified through field inspections, project documentation analysis, and structural behavior monitoring. These assessments aim to detect non-conformities, and engineering design firms propose technical solutions to address these issues. The primary goal of these reviews is to evaluate the overall state of conservation and structural safety, ensuring compliance with updated design criteria, revised standards, changing weather conditions, and technological advances. Dam renovations are crucial for enhancing operational capacity and preventive care. Implementing filtering materials within the dam's body establishes a drainage system to relieve internal pressures on the embankments and foundations. This prevents the washing away of soil particles due to internal erosion, known as "piping," a major cause of dam failures. Piping occurs when soil particles are displaced towards the outside of the embankment through the percolation process, particularly in the upstream area near the dam's base, where high hydraulic gradients and flows make it susceptible. This article presents a set of emergency or long-term solutions to address anomalies related to the onset of internal erosion in dams, with a focus on preventing piping. These solutions are vital for safeguarding the structural integrity and safety of these critical infrastructure components.

Use of Slag from Steelworks (BSSF and BOF) in the Manufacture of Concrete as a Possible Environmental Solution: Case Study with Tailings from the CSP of the Port of Pecém in Ceará
Authors: Silva Emerson Mariano , Freitas Francisco Ademir Eduardo , Campos Daniel Baracuy da Cunha
Published: July 2024

The increased demand for raw materials by the construction and processing industries, in particular steel produced from iron ore, has caused negative environmental impacts on the communities located around the steel industries. Therefore, this study validated the hypothesis that it is possible to use the waste produced and disposed of in steel mills (steel mill slag) in the construction industry. In this context, concrete manufacturing experiments were carried out by replacing the aggregate material (sand and cement) with steel mill slag (BSFF and BOF) and technical tests (particle size analysis, magnetic field testing, expansivity and axial strength) to prove the quality of the material produced. The results obtained show that the use of iron ore tailings produced at the Companhia Siderúrgica do Pecém (CSP) in the state of Ceará has potential to produce concrete that can be used in small and large constructions (low-income housing, asphalt sheets, buildings, and viaducts) and that this can help mitigate the negative effects of environmental pollution in the communities surrounding this region, helping to reduce environmental impacts.
Estado frente às Desigualdades Socioespaciais
Authors: Gomes de Lima Janaina Aparecida , De Almeida Souza Maria Angela , De Melo Rocha Danielle
Published: July 2024

Este artigo analisa como a questão das desigualdades socioespaciais vem sendo tratada por parte do Estado, elegendo como espaço analítico a cidade do Recife, núcleo de uma metrópole apontada como uma das mais desiguais do país. Parte do entendimento de que essas desigualdades se estruturam em três esferas de relações sociais – Estado, mercado e sociedade, adotando como foco as políticas públicas de intervenção e de regulação urbana, na sua relação com o setor imobiliário privado e com as comunidades residentes nos espaços de pobreza. Destaca que, no Recife, a desigualdade socioespacial se expressa pela proximidade e o contraste entre a produção imobiliária relacionada à atuação do setor privado e os numerosos assentamentos precários no território da cidade. Quanto aos métodos utilizados, em complemento à revisão bibliográfica sobre o papel central do Estado para o enfrentamento dessas desigualdades, procedeu-se à análise empírica pautada em referências teóricas, históricas e documentais, com foco na legislação urbanística incidente no Recife ao longo do tempo. Também se produziram mapas, retratando a dimensão espacial da dinâmica investigada. Os resultados destacam a identificação de três momentos emblemáticos, nos quais se demonstra que a postura estatal frente às desigualdades socioespaciais na cidade do Recife guarda proximidade com a produção imobiliária formal e informal. Conclui-se que os avanços mais significativos no enfrentamento das desigualdades socioespaciais nessa cidade foram obtidos quando as comunidades mais pobres apresentaram maior grau de organização e de articulação para incidir na gestão urbana.

Therapeutic drug monitoring is the practice of measuring the concentration of a drug in patient’s biological fluids to assess the effectiveness and safety of drug therapy. The results of determining the drug level in biological fluids can also indicate noncompliance of therapy regimen and low adherence to therapy.The aim. To compare the concentrations of some antiretroviral drugs (lopinavir, ritonavir, lamivudine, abacavir, zidovudine) in children living with HIV infection of different age groups.Methods. We examined 184 children with perinatal HIV infection who underwent therapeutic drug monitoring of nucleoside reverse transcriptase inhibitors (lamivudine, abacavir, zidovudine) and protease inhibitors (lopinavir, ritonavir). Children were divided into four age groups. Group 1 included children 1–2 years old (n = 7); group 2 – children 3–5 years old (n = 14); group 3 – children 6–11 years old (n = 78); group 4 – children 12–17 years old (n = 85). The concentration of antiretroviral drugs in blood plasma was determined using high-performance liquid chromatography with mass selective detection.Results. The lowest lopinavir concentration was found in children 12–17 years old (3782 [2117–5046] ng/ml), which was statistically significantly different from the similar values in children 6–11 years old (5614 [3521–7264] ng/ml; p = 0.011). For other antiretroviral drugs, no statistically significant differences in blood plasma concentrations were found in children of different age groups.Conclusion. The lowest lopinavir concentrations are detected in children older than 11 years. For the other studied antiretroviral drugs, this pattern was not revealed

Background. In recent years, special attention has been paid to the studying the consortia of probiotic bacteria. In these associations, the properties of individual microorganisms can be enhanced, in particular, their antagonistic activity which is an effective indicator for screening of probiotic potential. The development of probiotics based on such consortia with antibacterial properties is critical in the light of the growing problem of drug resistance in microorganisms.The aim of the work. To study the antagonistic activity of monocultures and consortia of lactobacilli against multidrug-resistant isolates of opportunistic bacteria. Materials and methods. The antagonistic activity of lactobacilli monocultures and their consortia was assessed simultaneously by two methods: the cross streak method and the well diffusion method.Results. All strains of lactobacilli and their consortia, depending on the research method, had varying degrees of antagonistic activity. Five consortia had stronger antagonism to test cultures as compared to monocultures, while in one consortium, the effect of antagonistic activity was reduced compared to monocultures. The results of studying the antagonistic activity of two consortia (Limosilactobacillus fermentum 44/1 and Lacticaseibacillus rhamnosus 12L, Latilactobacillus curvatus LCR-111-1 and Lactiplantibacillus plantarum 8PAZ) contradict data on the biocompatibility of strains in these consortia. Differences in the degree of antagonistic effects of lactobacilli on gram-positive and gram-negative species of opportunistic bacteria were revealed.Conclusion. The study showed that both the biocompatibility of the probiotic strains and the antagonistic activity of the consortium are the important requirements for creating a probiotic consortium with effective probiotic potential. To study the antagonistic properties of lactobacilli, the number of isolates of target gram-positive and gram-negative bacteria and normobiota should be increased. This will allow us to determine effective strategies for using probiotics in conditions of the spread of drug resistance of microorganisms.

Background. Setting of norms for the parameters of P300 cognitive auditory evoked potentials (EP) in elderly people with intact cognitive functions considering their residence in certain climatic and geographical regions is an urgent problem.The aim of the study. To determine age-related parameters of P300 cognitive auditory evoked potentials in elderly people aged 60–69 and 70–74 years, living in the European North of Russia (using the example of Arkhangelsk).Methods. The parameters of P300 auditory EP were determined in randomly selected urban residents in the age groups of 60–69 years (n = 284) and 70–74 years (n = 115) with normal scores on the Montreal Cognitive Assessment Scale (MoCA), without depression (according to Beck Depression Inventory), with preserved ability to work and/or social functions. We calculated the 5th–95th percentile values (P5– P95) of the P300 EP parameters and assessed the relationships of these parameters with socio-demographic characteristics, lifestyle and the results on the MoCA scale and Beck Depression Inventory.Results. Statistically significant differences in latency indicators of P300 EP were determined between groups of 60–69 and 70–74 years (P25–P90) in all studied brain regions (frontal, central). In the group of 60–69 years, the range of P25–P75 values of P300 EP latencies was 342.5–401 ms, in the group of 70–74 years – 358.5–443 ms. Age differences in P300 EP amplitudes were minimal with an interquartile range of 4–13 μV in the total sample. Participants who smoked had higher latency scores and lower amplitude scores; former smokers had higher latency scores compared to never-smokers.Conclusion. Latency above 400 ms at the age of 60–65 years and above 443 ms at 70–74 years can be considered as a criterion for reduced cognitive reserve and an increased risk of developing cognitive disorders in elderly people living in the European North of Russia.

The problem of the structural and functional effectiveness of episcleral and endovitreal treatment methods of rhegmatogenous retinal detachment remains open to this day.The aim of the study. To assess the clinical effectiveness of surgical treatment of rhegmatogenous retinal detachment using episcleral and endovitreal methods.Material and methods. An analysis of the electronic database and a detailed assessment of the treatment of 285 patients with rhegmatogenous retinal detachment for 2005–2022 were carried out. A comparative analysis was made in two groups: group 1 – patients after episcleral surgery (n = 155); group 2 – patients after endovitreal surgery (n = 130). The initial condition and the extent of surgery were comparable. Results. From 2005 to 2009 in 65.9 % of cases, episcleral buckling predominated; from 2009 to 2021 – posterior closed vitrectomy (in 64.8–88.7 % of cases). The incidence of primary retinal reattachment was 74.2 % and 71.5 %. The number of relapses after vitreoretinal surgery slightly exceeded the values in the group 1 – 28.4 % versus 25.7 %, and in 20% of cases the first relapse occurred before silicone aspiration as a result of subsilicone proliferation. The total number of surgical interventions per person, taking into account mandatory silicone aspiration, in the group 1 was 1.3, in the group 2 – 2.25 for the entire observation period. The visual acuity of patients in group 1 was 2 times higher than that of the comparison group – 0.21 ± 0.02 and 0.1 ± 0.03, respectively (p < 0.05).Conclusion. Episcleral treatment methods of rhegmatogenous retinal detachment are characterized by better anatomical, reconstructive and functional effects with fewer re-operations

Background. Cataract is one of the main causes of decreased visual acuity in the world, and therefore scientists are continuing researches on the mechanisms of development of this ophthalmic pathology.The aim. To study metabolic changes in a cloudy lens using an experimental model.Materials and methods. The study was carried out on adult male Wistar rats (n = 60), which were divided into control (n = 30) and experimental (n = 30) groups. Experimental cataract were simulated by daily ultraviolet irradiation (λ = 300–350 nm) during 6 months for 20 minutes. At the months 2, 4 and 6 of the study, we carried out a biomicroscopic examination of the anterior eye of animals using a slit lamp to monitor the development of cataract. Lenses were collected to determine the content of stearoyl-coenzyme-A desaturases and melatonin using enzyme immunoassay.Results. At the stage of initial cataract, the content of the stearoyl-coenzyme A desaturase was statistically significantly lower than the control values by 38 %; at the stage of immature cataract – by 30 %; at the stage of mature cataract – by 15.4 %. It was revealed that at the month 6 of the study, the concentration of melatonin in lens homogenates was 17 % lower when compared with the control. A statistically significant correlation was established between stearoyl-coenzyme A desaturase and melatonin (r = 0.32).Conclusion. Melatonin and stearoyl-coenzyme A desaturase play an important role in a number of biochemical processes that ensure the proper functioning of the visual analyzer. Changes in the concentration of these biological molecules can play a key role in the pathogenesis of cataract and a number of other ophthalmic diseases

The aim. To study the predisposing factors for the development and timing of development of intraventricular hemorrhage (IVH) in extremely premature newborns.Materials and methods. We carried out retrospective analysis of 32 case histories of children born at a gestational age of less than 32 weeks. The children were divided into three groups: group 1 (n = 13) – children death was caused by non-traumatic IVH; group 2 (n = 12) – surviving infants with IVH; group 3 (comparison group; n = 7) – premature infants without IVH. We assessed risk factors for the development of IVH, their severity, and main indicators predisposing to death in newborns of these groups.Results. Children of the group 1 had statistically significantly low values of body weight – 670 [640–860] g (р1–2 = 0.007; р1–3 = 0.012), head circumference – 23 [22–24] cm (р1–2 = 0.008; р1–3 = 0.049), gestational age – 24.5 [23.5–25.5] weeks (р1–2 = 0.002; р1–3 = 0.007). Gender differences were revealed: in the group 1, there were 92.3 % of boys, in the group 2 – 33.3 % (p1–2 = 0.008). Maternal smoking increased the risk of fatal IVH by 3.5 ± 0.15 times, polyhydramnios – by 3.3 ± 0.37 times, chorioamnionitis – by 12.8 ± 0.47 times, placenta previa – by 3.2 ± 0.15 times. In newborns of the group 1, seizures developed on the day 1 of life in 84.6 % (more often than in group 2; p = 0.00001), and shock in the first 3 hours of life was recorded in 46.1 % of cases (р1–2 = 0.034), which increased the risk of death by 4.3 ± 0.47 times. In newborns of group 1, compared with newborns of groups 2 and 3, pulmonary hypertension was more often detected (60.8 [50.1–69.2] mm Hg; p1–2 = 0.028; p1–3 = 0.047).Conclusion. Confirmed infectious diseases in the mother, clinical manifestation of convulsions, pulmonary hypertension, development of multiple organ failure and shock in extremely premature newborns increase the risk of intraventricular hemorrhage and the frequency of deaths.
Quality assessment of the screening test for predictors of coronary heart disease

Background. Coronary heart disease (CHD) ranks first among the causes of death, morbidity, and disablement. The development of innovative methods for predicting CHD will reduce these losses.The aim of the work. To assess the quality of the screening test for predictors of coronary heart disease using statistical quality control of a verifiable diagnostic test (with binary outcomes).Materials and methods. In 2008–2013, 70 cases of CHD were registered in a groupof 7959 initially healthy men 18–66 years old who were the members of locomotive crews. Statistical analysis identified CHD predictors: arterial hypertension; psychosocial stress; hyperglycemia; dyslipidemia; excessive alcohol consumption; obesity of degree I–III; age 34–66 years; microalbuminuria; thickening of the intima- media complex/atherosclerotic plaque (IMC/ASP); pulse wave velocity (PWV) > 12 m/s; left ventricular hypertrophy; grade I–II retinopathy; atherosclerosis of aorta. DiagStat (Russian Federation) software determined their predictive ability when used in screening tests to predict CHD. We demonstrated the use of this method to assess the predictive ability of risk factors for any disease.Results. CHD predictors have high to moderate specificity for the absence of CHD in individuals who test negative for the above-listed factors. IMC/ASP, microalbuminuria, PWV > 12 m/s, grade III obesity moderately increase the posterior odds of developing CHD versus its absence in comparison with the prior odds after receiving a positive result of the verifiable diagnostic test for these factors. Age 34–66 years moderately increases the posterior odds in favor of the absence of CHD versus its occurrence compared with the prior odds after receiving a negative result of the verifiable diagnostic test.Conclusion. When assessing the result of the verifiable diagnostic test, we should focus on both the probability of occurrence and the absence of CHD in the presence or absence of a predictor in the patient. Since the determination of PWV > 12 m/s, atherosclerosis of aorta, microalbuminuria, stress, and excessive alcohol consumption among workers of locomotive crews is not mandatory, it is necessary to conduct a targeted search for them

Background. The etiological structure of implant-associated infection and antibiotic resistance of pathogens are important when choosing empirical antibiotic therapy. COVID-19 pandemic and increased consumption of antibiotics by the population could provoke an increase in antibiotic resistance.The aim of the work. To compare the spectrum of leading pathogens of implantassociated infection in the pre- and post-Covid period and to assess antibiotic resistance.Materials and methods. A continuous retrospective study of biomaterial samples from traumatology and orthopedic patients with implant-associated infection was carried out for 2018–2019 and 2021–2022. The sample consisted of 548 microorganism strains (n = 237 and n = 317, respectively) in 442 cases of infectious complications. The antibiotic resistance of all isolated microorganisms, including those from microbial associations, was assessed.Results. The leading pathogen of monomicrobial implant-associated infection in both study periods was Staphylococcus epidermidis (33–37 %). In 2021–2022, the proportion of microbial associations increased (from 12.5 to 17.5 %; p = 0.147) with the appearance of fungi in the microbial landscape. In the post-Covid period, the increase in Staphylococcus aureus resistance to tetracycline and doxycycline was revealed; the isolation of methicillin-resistant strains among Staphylococcus aureus decreased from 4 cases (out of 187) to 3 (out of 232); 100 % sensitivity to rifampicin and co-trimoxazole was maintained. An increase in Staphylococcus epidermidis resistance to all tested antibiotics was detected (statistically significant increase in resistance to fluoroquinolones; p = 0.002–0.003) with the isolation of methicillin-resistant strains in 80.5% and 80.9% of cases, respectively. All staphylococcal isolates were susceptible to vancomycin and linezolid. Enterobacteriaceae representatives showed a decrease in resistance to carbapenems and an increase in resistance to co-trimoxazole; in Pseudomonas aeruginosa and Acinetobacter baumannii, there is an increase in resistance to carbapenems and fluoroquinolones. All gram-negative microorganisms were sensitive to colistin.Conclusion. The high frequency of isolation of methicillin-resistant staphylococci determines the choice of vancomycin for empirical therapy. Increasing resistance of staphylococci to fluoroquinolones may limit their use. Increasing resistance of gram-negative bacteria and a narrow spectrum of antibiotics acting on carbapenemase producers may reduce the effectiveness of therapy.
