STUDY OF THE LIV VERTEBRAL BODY LOAD DURING DYNAMIC SIMULATION OF MOVEMENTS IN THE LUMBAR SPINE USING MUSCULOSKELETAL MODELS AFTER POSTERIOR BISEGMENTAL SPINE FUSION PERFORMANCE
Authors: Barkov Oleksandr , Malyk Roman , Karpinska Olena
Published: October 2023

One of the risk factors for complications in the spinal motion segments of the thoracic and lumbar regions, as well as in the adjacent segments with spinal fusion ones, is changes in the sagittal vertebral-pelvic balance. Purpose. To determine the effect of muscle changes that occur during the performance of two-segment LIV–SI spinal fusion on the load of adjacent motion segments. Material and methods. The spinal fusion of two spinal motion segments of the lumbar spine was simulated at the LIV–LV and LV–SI levels at different angles of segment fixation in the OpenSim programme. Five models were analysed: 1 (basic) — without changes; 2 — changes in the points of attachment and muscle strength; 3 — normo-lordotic fixation; 4 — hypolordotic; 5 —hyperlordotic. The load on the zone of interest was measured as the magnitude of the projection of the force vector depending on the angle of inclination of the torso as a percentage of the body weight. Results. Simulation of the above configurations of the instrumental spinal fusion (intact, normo-lordotic, hyperlordotic, hypolordotic positions due to a change in the angle of the LIV–SI spinal fusion) showed that the load force of the adjacent segments when bent forward depended on the angle of the instrumental spinal fusion performed. Conclusions. As a result of study of the kinematic model of the lumbar spine using bisegmental spinal fusion of LIV–SI, it was proved that the load force of the adjacent segments when bent forward depended on the angle of the instrumental spinal fusion performed. It was determined that the upper adjacent vertebra of the fixation zone had a relatively insignificant increase in load in the case of fixation in the hyperlordotic position; in the hypolordotic position, the load on the upper segment led to an increase in loads on the upper adjacent segment, and in the hypolordic position, it led to a slight decrease compared to the normo-lordotic fixation. According to the results of the study, minimal muscle damage is expected during the surgical intervention, so the reliability of the model is closer to minimally invasive surgery. The developed kinematic models can be useful in the planning of the transpedicular fixation surgery to prevent complications.

Objective. To conduct a finite element analysis of the stress-strain state (STS) of the elements of the shoulder joint after implantation reverse shoulder endoprostheses. Material and methods. After 3Dscanning of the composite model of the scapula and humerus, geometric models of the shoulder joint were built in the SolidWorks 2019 SP 1.0 program, followed by mathematical modeling and FEA. For the comparative analysis of the STS of the «bone – reverse endoprosthesis» s ystem, t hree-dimensional m odels o f two types of reverse shoulder endoprostheses were created, which were then transformed into a finite-element model and implanted into the developed three-dimensional mathematical model of the shoulder joint without cement. The STS calculations of the elements of endoprostheses were carried out for two positions: abduction 90° and flexion 90° with a load of 5 kg. Results. Compared to the healthy shoulder joint, models with reverse shoulder endoprosthesis have significantly different contact stresses and contact areas. It was established that the maximum stress in the details of the contact parts of the endoprosthesis when retracted at an angle of 90° did not exceed +1.78 MPa, when bending +5.8 MPa. The maximum stresses on the liner during shoulder abduction are +8.6 MPa, the minimum –7.38 MPa, during flexion +2.3 MPa and –2.45 MPa, respectively. It has been proven that the contact areas of the hemisphere and inserts of both reverse endoprostheses during abduction and flexion of the limb by 90° are significantly larger (573 mm2 vs. 1809–2081 mm2) when compared with a healthy shoulder joint, while changes in the area between the endoprostheses are insignificant and equal to 2...3 %. Conclusions. Analysis of the STS load of elements of reverse shoulder endoprosthesis showed that the greatest stresses occur in the contact zones. It has been proven that the maximum stresses on the contact structures of endoprostheses are less than on the head of a healthy joint, but the contact area during implantation of a reversible endoprosthesis of the shoulder joint increases significantly (more than 3 times).

Authors: Baburkina Olena , Ovchynnikov Oleg , Bludova Maryna , Zhygun Anatoliy
Published: October 2023

In the modern world, despite the increased availability of hightech orthopedic care, the number of patients with gonarthrosis does not decrease, and thanks to public awareness, more and more people turn to orthopedists for surgical help. Due to its high efficiency, the leading role in the treatment of terminal gonarthrosis has been firmly occupied by total knee arthroplasty for more than four decades. Unicondylar knee arthroplasty in patients with unilateral arthrosis allows to largely preserve physiological kinematics, to achieve minimal bone and soft tissue traumatization during surgery and, as a result, to obtain a higher functional result. The objective of the work is to analyze the data of the world literature regarding unicondylar knee arthroplasty, its advantages and disadvantages. Material and methods. The authors analyzed the publications devoted to single-condylar knee arthroplasty from the Google search engine, scientific and metric electronic databases PubMed, Medline and other relevant sources of scientific and medical information. Correct patient selection is vital to ensure a successful outcome with OEKS. The main indication for OEKS is deforming arthrosis of the II–III century. with a predominant lesion of the internal part of the knee joint and varus deformation of the lower limb or with a more pronounced pathology of the external part of the knee joint and valgus deformation of the lower limb. Results. The authors analyzed the literature sources on single-condylar endoprosthesis of the knee joint. Indications, contraindications, biomechanical features, type of endoprosthesis fixation, type of endoprosthesis platform, features of lateral gonarthrosis, and complications of single-condylar knee arthroplasty are determined. Conclusions. The analysis of selected literary sources showed that single-condylar arthroplasty of the knee joint is an effective means of preserving the bone. However, careful patient selection and precision of surgical technique remain the key to a successful outcome.

Crosstalk between ESKAPE bacteria and NK cells: mutual regulation and role in developing reproductive tract pathologies
Authors: Grebenkina Polina V. , Selkov Sergey A. , Kraeva Lyudmila А. , Sokolov Dmitriy I.
Published: October 2023

Natural killer (NK) cells represent one of the innate lymphoid cell subsets, which are often studied in the context of antitumor and antiviral immunity, as well as due to their localization in the zone of the mother-fetus contact (in the uterus), therefore underlying their extensive investigation in developing pregnancy. At the same time, their role in antibacterial immune response has been poorly examined. Because NK cells can produce cytokines, one of putative options for their participation in eliminating prokaryotic pathogens may be coupled to regulation of immune system cells such as dendritic cells, macrophages, etc. However, there have been also described variants of contact cytolysis of cells infected with intracellular bacteria enabled due to cytotoxic proteins perforin, granzymes, granulisin found in NK cells. In recent years, it has become known that NK cells take part in development of immune response against extracellular bacteria including the ESKAPE group bacteria, which includes opportunistic prokaryotes that most actively develop antibiotic resistance and cause nosocomial infections. Here, we attempted to review the data on the role NK cells play in antibacterial immunity. Assessing a crosstalk between ESKAPE group bacteria and NK cells also attracts researchers due to the ability of prokaryotes to alter functions of immune cells, but very little is known about the effects they exert on NK cells. At the same time, such data could be applied to seek out for new ways to treat oncological diseases as well as pave the basis for new approaches to regulating NK cell characteristics in reproductive pathologies. As mentioned earlier, the latter occur in the decidual membrane, where they can interact with fetal cells including trophoblast cells. It is believed that cells can mutually regulate each others properties necessary for the course of physiological pregnancy. Probably, imbalance in this system can lead to development of reproductive pathologies. The review summarizes the currently available data on the effects of ESKAPE group bacteria on NK cells, and also considers putative mechanisms for emergence of impaired interaction between NK cells and trophoblasts exposed to ESKAPE group bacteria. Owing to few publications available on this phenomenon, the experimental study assessing an impact of ESKAPE group bacteria on NK cell properties is envisioned as a necessary stage in development of contemporary biology.

Published: October 2023

Background. Numerous hemodialysis patients (HD) suffer from severe, life-threatening inflammation that must be treated to prevent further complications. Early diagnosis of inflammation in HD is highly needed. The present study used matrix metalloproteinase-1 (MMP3) and tissue inhibitor of metalloproteinases-1 (TIMP1) to differentiate between patients with/without inflammation using the neural network analysis (NN).
Methods. The positive results of C-reactive protein were used as a criterion for the presence of inflammation in the patients (HD+CRP) versus the negative group (HD-CRP). The NN analysis was used to discriminate between groups using the measured biomarkers.
Results. HD+CRP patients have a higher duration of disease, MMP3 and lower calcium than the HD-CRP level is significantly higher, while vitamin D is significantly lower in the HD+CRP group compared with both other groups (all p0.05). TIMP1 is significantly correlated with inorganic phosphate and CRP. In NN#1, the model for the prediction of HD+CRP from HD-CRP has an area under the curve (AUC) of the receiver operating characteristic (ROC) of 0.907 with a sensitivity and specificity 89.2% and a specificity of 100.0%. The top predicting variable for the prediction of HD+CRP is MMP3 (100%), followed by creatinine (87.1%). MMP3 is linked to the pathophysiology of HD, at least through their correlation with the inflammation in HD. In NN#2, the AUC of the ROC for predicting the kidney disease and subsequent HD was 98.9%, with a sensitivity of 100.0% and a specificity of 97.1%. The top four predicting variables for the prediction of high risk of inflammation in HD patients are urea (100%), creatinine (100%), MMP3 (59.7%), and vitamin D (57.1%).
Conclusion. The NN analysis may differentiate between HD patients with inflammation from the HD without inflammation. Also, the measured parameters, especially MMP3, TIMP1, and vitamin D are useful as a diagnostic tools for the kidney diseases and inflammation linked with the disease.
Entre erros férteis e verdades anódinas: sobre “Foucault, a arqueologia e as palavras e as coisas: cinquenta anos depois”, de Ivan Domingues
Authors: Candiotto Cesar
Published: October 2023

Resumo: O objetivo deste artigo consiste em tecer uma apreciação da recepção de As palavras e as coisas, de Michel Foucault, a partir do último livro de Ivan Domingues, intitulado “Foucault, a arqueologia e As palavras e as coisas: cinquenta anos depois” (Ed. UFMG, 2023). Um dos escopos do livro é examinar o alcance de As palavras e as coisas e sua estratégia arqueológica, para dar conta da apresentação do nascimento das ciências humanas, bem como de sua fragilidade e instabilidade, diante de uma possível mudança na disposição do saber, cujos sinais podem ser observados por ocasião do advento, no século XX, da psicanálise lacaniana, da etnologia e da linguística estrutural. Ao privilegiar suas repercussões, expansões e retificações, cinquenta anos depois, não se tem a pretensão de “corrigir” Foucault, em função de um olhar de epistemólogo, todavia, apontar a fertilidade e a potência de seu pensamento para a posteridade. Trata-se de trafegar entre “[...] erros férteis e verdades anódinas.” (DOMINGUES, 2020, p. 386). A aposta é que possíveis hiatos, erros ou confusões identificáveis pelo próprio Foucault e por seus críticos, à época, jamais invalidam a fertilidade de uma discussão acerca das ciências humanas, as quais nunca mais foram as mesmas depois dele.

Abstract: The study aimed to estimate the prevalence of minimum dietary diversity (MDD) and consumption of ultra-processed foods in children 6-23 months of age according to sociodemographic variables. Three indicators of complementary feeding of 4,354 children from the Brazilian National Survey on Child Nutrition (ENANI-2019) were built based on a questionnaire about food consumption on the day before the interview: MDD, consumption of ultra-processed foods, and MDD without the consumption of ultra-processed foods. The prevalence and 95%CI were calculated, stratified by macroregion; race/skin color, education and work status of the mother or caregiver; enrollment in the Brazilian Income Transfer Program; household food security; sanitation; and child enrollment in daycare/school. The overall prevalence of MDD was 63.4%, with lower prevalences among children who lived in the North Region (54.8%), whose mothers or caregivers had 0-7 years of education (50.6%), and lived under moderate or severe food insecurity (52.6%). Ultra-processed foods were consumed by 80.5% of the children, with the highest prevalence in the North Region (84.5%). The prevalence of MDD without ultra-processed foods was 8.4% and less prevalent among children with black mothers or caregivers (3.6%) and among those whose mother or caregiver had 8-10 years of education (3.6%). The most frequently consumed food groups from the MDD indicator were grains, roots and tubers (90.2%), dairy products (81%) and those from ultra-processed food were sweet or salty cookies/crackers (51.3%) and instant flours (41.4%). The ubiquitous presence of ultra-processed foods in the diets of Brazilian children and the low frequency of diversified foods, especially among the most vulnerable populations, indicate the need to strengthen policies and programs to ensure adequate and healthy infant nutrition.

ABSTRACT: Pineapple is a tropical fruit with high demand by the fruit market in Brazil. Fruits of the cultivar ´Turiaçu` stans out in local consumer markets due to its excellent quality. The objective of this work was to evaluate ecophysiological responses of ´Turiaçu` pineapple plants at the vegetative and reproductive stages to soil fertilization and crop location, and their effects in fruit yield. The study was conducted in the cities of São Luís and Turiaçu, MA, Brazil. Plants under mineral and organic fertilization in two locations, São Luís and Turiaçu, and in two seasons, dry and rainy season, were evaluated during dry and rainy seasons. Chlorophyll index, photochemical efficiency, gas exchange, and fruit yield were evaluated. The pineapple plants presented decrease in the photosynthetic activity, at both developmental stages and in both seasons, when grown in São Luís. The CO2 photosynthetic assimilation decreased. The PSI and PSII activity, according with photosynthetic index, was more sensitive at the reproductive than at the vegetative stage. The organic fertilization was not appropriate for the ´Turiaçu` pineapple crops, regardless of the crop location. The fruit yields were 54.4% and 57.9% lower in São Luís, under mineral and organic fertilization, respectively. Thus, the ecophysiology of ´Turiaçu` pineapple was more affected by water availability than by soil fertility in the municipality of Turiaçu.

Published: October 2023

ABSTRACT: Acute liver injury (ALI) is an important medical problem that requires effective therapy. Astaxanthin (AST) is a carotenoid, and the beneficial effects of astaxanthin, including anti-oxidative, anti-inflammatory and anti-tumour activities, have been identified. The present study was designed to elucidate the protective effects of astaxanthin against ALI and their underlying mechanisms. RAW264.7 macrophages were treated with dimethyl sulfoxide combined with different doses of astaxanthin for 12 h. Mice were fed with or without astaxanthin for up to 7 days. LPS was administered to induce inflammation. We assessed histopathology, oxidative stress, inflammation and apoptosis .The results indicated that astaxanthin attenuated LPS-induced oxidative stress, inflammation and cell apoptosis both in vivo and in vitro. In vivo and in vitro experiments showed that astaxanthin down regulated the nuclear factor-kappa beta (NF-κB), nuclear factor erythroid 2-related factor 2 (Nrf2) and NLR family pyrin domain containing 3 (NLRP3) signalling pathways, inhibiting the LPS-induced inflammatory response, oxidative stress and cell apoptosis, and alleviating LPS-induced ALI in mice.

Published: October 2023

Abstract The first list of Aetalionidae and Membracidae species for western Acre is presented, including the Alto do Juruá regions of Serra do Divisor National Park and the Campus Floresta of the Federal University of Acre. In total, 94 species of treehoppers were collected, of which Centrotinae (Membracidae) is recorded for the first time for Brazil (Abelus maculatus Schimidt), another 16 species are new Brazilian records, and 69 species (Aetalionidae and Membracidae) are new records for Acre. Data on type locality, geographic distribution and images of all species are presented. The males of Lophyraspis fenestrata Sakakibara & Creão-Duarte and Erechtia sanguinolenta (Fairmaire) are known for the first time. The species diversity was compared to four other treehopper surveys in the Amazon region, with similarity indices of about 43.6% for Colombian Amazon (at least 650 km away), 27.6% for Panguana Biological Research Station, Peru (250 km), 20.2% for Adolpho Ducke Forest Reserve, Brazil (1,600 km) and 8.5% for Villa Carmen Biological Station/Los Amigos Biological Station, Peru (600/700 km). The estimated richness of Serra do Divisor National Park was just over 70%, suggesting that local diversity could be significantly higher than that presented in this study.
O discurso acadêmico do professor de inglês em perspectiva dialógica
Authors: Lima Samuel de Carvalho
Published: October 2023

RESUMO O objetivo deste artigo é discutir a constituição do discurso acadêmico do professor de inglês sobre experiências exitosas no ensino da língua. Para isso, filio-me à Linguística Aplicada e adoto a perspectiva dialógica da linguagem para explorar 12 resumos de comunicações publicados no caderno de resumos do III Seminário Internacional da Associação Brasileira de Professores de Língua Inglesa na Rede Federal de Ensino Básico, Técnico e Tecnológico (ABRALITEC) em 2020. Os resumos são tomados como enunciados imbuídos do discurso oficial sobre o ensino de inglês no Brasil e do discurso teórico mobilizado para a realização da investigação no campo da atividade científica. A análise dialógica do corpus elucidou que o discurso acadêmico do professor de inglês se bivocaliza com o discurso teórico por meio da nomenclatura de conceitos e da citação a autores para fundamentar teorias pedagógica, metodológica e de linguagem, ao passo que se bivocaliza com o discurso oficial por meio da inserção de léxico específico ou da menção à política de educação linguística para complementá-la ou transgredi-la.

Published: October 2023

RESUMEN La escritura académica cumple una función central en la producción y difusión del conocimiento, propósito fundamental en la formación posgraduada. El artículo da cuenta de uno de los casos estudiados, como parte de una investigación más amplia, cuyo objetivo fue comprender las transformaciones en la escritura académica de estudiantes de posgrado de tres regiones colombianas. Este caso tuvo el propósito de comprender las transformaciones en la escritura de un contexto intercultural, conformado por 18 estudiantes, siete de los cuales pertenecen a un pueblo indígena colombiano. Se tomaron las producciones escritas elaboradas al iniciar y finalizar el posgrado, para ser analizadas desde las categorías: Locutor/Enunciador, Interlocutor/Enunciatario, Tema/ Lo Enunciado, Superestructura y Macro/Microestructura, fundamentadas en la perspectiva discursiva interactiva de Martínez et al. (2004). Los resultados ponen en evidencia que, pese a las transformaciones positivas de todos los escritos, aún persisten dificultades, especialmente en los estudiantes indígenas, asunto que puede ser factor de exclusión dentro de las comunidades académicas y que invita a reflexionar sobre nuevas formas de asumir la alfabetización académica en contextos interculturales.
“Anhedonia”: um conto cubano em perspectiva multirrede-discursiva na formação de professores de espanhol

Published: October 2023

RESUMO Partindo da compreensão da relação constitutiva entre língua e literatura e do poderoso papel da literatura na formação do sujeito, este trabalho pretende inserir-se nas discussões travadas por linguistas aplicados a respeito da inclusão da literatura em planejamentos curriculares na área de formação de professores de espanhol. Mobilizando a Proposta Multirrede-Discursiva (Serrani, 2010, 2020), este artigo apresenta o conto “Anhedonia”, da cubana Mylene Fernández Pintado (2013), a partir de critérios multirrede-discursivos, e discute uma proposta de práticas de linguagens que permitam enfocar, de forma articulada, o tema sociocultural: a mulher (cubana) e sua representação em sociedade, e a heterogeneidade discursiva como tema de língua-discurso, materializada no discurso relatado, sempre visando à formação intercultural de professores de espanhol. Nas oficinas apresentadas estabeleceu-se uma rede semântica a partir de textos em gêneros discursivos diversos com posições diferentes sobre o tema sociocultural em debate, o que pode possibilitar uma melhor compreensão deste e contribuir com uma formação compromissada com a cidadania.
As construções [que x o que] e [que x que nada] no português brasileiro
Authors: Batista Hadinei Ribeiro
Published: October 2023

RESUMO Este artigo tem como meta investigar o uso e emergência das construções [que x o que] e [que x que nada] com base no aparato teórico da abordagem construcionista (Goldberg, 1995; Croft & Cruise, 2004; Traugott & Trousdale, 2013). Tais construções, recorrentes na modalidade oral do português brasileiro em situações de diálogo, funcionam como mecanismo de discordância, incorporando a informação linguística a ser refutada (explícita ou não no evento comunicativo), operando no mesmo nível de expressões cristalizadas como as idiomáticas. Os dados analisados foram extraídos do corpus C-Oral Brasil, pesquisa na plataforma Google e Corpus do Português. Neste estudo, o foco reside em compreender as motivações de natureza formal e funcional do emprego dessas construções nas situações reais de uso da língua. Os resultados apontam complexidade na interpretação dessas expressões quanto ao pareamento forma-função, haja vista que a gradiência desse pareamento é relativamente abruta e resulta de processos polissêmicos.
Traços da história do gênero discursivo infográfico no jornalismo impresso do Sul e Sudeste brasileiro: entre conservação e evolução

Published: October 2023

RESUMO O infográfico é um gênero do discurso que, gradualmente, ganha espaço e capilaridade no jornalismo impresso brasileiro, embora a sua história seja pouco explorada. Em razão disso, o objetivo deste artigo é analisar os traços de permanência e mudança na história do infográfico em jornais diários das regiões Sul e Sudeste do país a partir de um corpus de 30 textos divididos igualmente entre os períodos de 1990-1995 e 2015-2020. Trata-se de um estudo diacrônico e de uma pesquisa de natureza qualitativa, que emprega métodos quantitativos para fins específicos. Ancoramo-nos, teoricamente, na perspectiva de Tradições Discursivas (TD), mobilizando também a teoria de gênero do discurso. Como resultados, concluímos que, a título de conservação, as TD de conteúdo jornalístico, linguagem objetiva, título, corpo do infográfico, elementos de detalhamento, fonte, autoria e fotomontagem permaneceram sem expressivas alterações entre os períodos, enquanto as TD de valoração proeminente, lead, acabamento complementar e independente, ainda que mantidas, sofreram bastante alterações entre os recortes temporais. Em caráter de evolução, apareceram as TD de desenho digital, conteúdo complementar e linguagem informal. Por fim, as TD de desenho à mão e protoinfográfico desaparecem do recorte sócio-histórico analisado.

ABSTRACT: Ionophores are antibiotics frequently used in animals of production. The most common are monensin, salinomycin, narasin, and lasalocid. The equine species is highly susceptible to ionophores poisoning. The present study aimed to analyze the serum use of cardiac troponin I (cTnI) and the anti-troponin C immunohistochemistry (IHC) technique (anti-cTnC) as a diagnostic tool for cardiac injuries in horses spontaneously poisoned by salinomycin. Seven horses were affected by a disease lasting for 6-72 hours. Three horses recovered. The primary morphological lesions reported in the four necropsied horses that died spontaneously were necrosis of the myocardium and skeletal muscle. Immunohistochemistry for anti-cTnC was performed in selected sections of the cardiac muscle from the equine submitted for necropsy. A decrease in cTnC expression in the cytoplasm of cardiomyocytes was noticed in all four necropsied horses. Samples of serum from six horses tested for cardiac troponin I levels; the most expressive values were mainly in horses with more severe cardiac histological lesions. The serum detection of cTnI can be considered a good marker to determine cardiac damage in horses intoxicated with salinomycin with a clinical evolution of 48 hours or more. The anti-cTnC IHC aided in the detection of cardiac injury in horses independent of clinical evolution.

ABSTRACT Phenology is defined as the study of the timing of biological events and the biotic and abiotic factors that trigger them. This study reports a description of the phenology of Byrsonima pachyphylla and B. verbascifolia in an ecotonal area between the Cerrado and Amazonia biomes in the Brazilian state of Tocantins, to contribute to a better understanding of their autoecology in this region. Two populations of 15 adult individuals of each species, randomly selected in a Cerrado area in Porto Nacional, Tocantins, were surveyed for 12 months. Percentages were estimated of leaf flush, young, mature, and senescent leaves (vegetative phenology), flower buds, open flowers, green and ripe fruits (reproductive phenology) present in the canopy, as well as the synchrony of the reproductive phenophases. The vegetative and reproductive phenological events were seasonal and occurred mainly at the end of the dry season and during the transition from the dry to the rainy season. Considering the vegetative and reproductive phenology, B. pachyphylla was classified as “evergreen with continuous growth” and as a late-flowering species, whereas B. verbascifolia was classified as “evergreen with seasonal growth” and as an early-flowering species. The reproductive phenological activity of the species exhibited high synchrony. The results suggest that the vegetative and reproductive events are peculiar to each species and represent effective strategies for their survival in the Cerrado, which is markedly seasonal.

ABSTRACT Astrocaryum aculeatum Mart. Moreover, Astrocaryum acaule Mart. are palm trees with ecological and extractive importance in the Amazon. These are hearty species that have been associated with archaeological sites and thrive in the presence of humans in certain areas. This work aimed to verify the effect of global climate change on the potential geographic distribution of A. acaule and A. aculeatum in the current period and future climate scenarios using ecological niche modeling in Brazilian phytogeographic domains. The modeling was based on 19 bioclimatic variables obtained from the Worldclim website and four algorithms (Climate space model, Envelope Score, Niche Mosaic, and Environmental Distance). Additionally, the Environmental Distance algorithm showed greater similarity regarding species distribution with potential occurrence in the five Brazilian domains (Amazon, Pantanal, Caatinga, Cerrado, and Atlantic Forest). The dispersion patterns were very similar between the two Astrocaryum palms though A. aculeatum was more sensitive to climatic variations. A. acaule may be more resilient to changes, as demonstrated by being able to recolonize in the southern portion of the Amazon in future scenarios in the year 2070. The modeling helped to delimit potential areas for A. aculeatum and A. acaule, indicating the need for the conservation of the species in more sensitive regions.

Resumo Objetivos: analisar a tendência temporal e a distribuição espacial da mortalidade infantil em Pernambuco no período de 2001 a 2019. Métodos: estudo ecológico envolvendo todos os óbitos em crianças menores de um ano residentes no estado. Os dados foram coletados no Sistema de Informações sobre Mortalidade e no Sistema de Informação sobre Nascidos Vivos. Foram calculados quatro coeficientes de mortalidade e a análise temporal foi realizada aplicando o modelo de regressão por pontos de inflexão dos coeficientes em diferentes níveis espaciais. Resultados: foram registrados 47.949 óbitos, dos quais 51,0% (n=24.447) ocorreram nos seis primeiros dias de vida. Foi observada tendência de declínio estatisticamente significativo em todos os coeficientes analisados (-4,5%/ano na mortalidade geral, -3,6%/ano na neonatal precoce, -1,9%/ano no componente neonatal tardio e de -6,3%/ano no componente pós-neonatal). Adicionalmente, 64,3% dos municípios (n=119) apresentaram tendência de declínio no coeficiente de mortalidade infantil geral. Menos de 50% dos municípios apresentaram tendência de redução na mortalidade neonatal precoce e neonatal tardia (41,08%; n=76 e 43,2%; n=80, respectivamente). Na mortalidade pós-neonatal, 57,3% (n=106) apresentaram tendências decrescentes. Conclusões: houve tendência temporal de declínio da mortalidade infantil geral, embora haja importante parcela de municípios com tendência estacionária, justificando a necessidade de reduzir desigualdades sociais e assimetrias geográficas.

Abstract Objectives: to evaluate coverage and identify factors associated with adequate prenatal care for adolescent mothers in Rio Grande, Southern Brazil, in a period of 13 years. Methods: over the years 2007, 2010, 2013, 2016 and 2019, a single standardized questionnaire was applied to all mothers at hospital level in this municipality. The outcome consisted of the proportion of puerperae women who started prenatal care in the first trimester and performed 6+ medical visits, completed 2+ HIV, syphilis, and urine tests. Chi-square test was used for proportions, Poisson regression in the multivariate analysis and the prevalence ratio (PR) as measure of effect. Results: among the 12,645 identified mothers, 2,184 (17.3%) were adolescents. Of this total, 35.2% (CI95%= 33.2%-37.2%) had received adequate prenatal care, ranging from 13.8% (10.8%-16.7%) in 2007 to 52,5% (46.8%-58.1%) in 2019. The adjusted analysis showed a higher PR for adequate prenatal care among those of older age and better schooling level, white/brown skin color, with a partner, never had an abortion, were primiparous and non-smokers. Conclusion: there was substantial improvement in coverage of adequate prenatal care over the period studied, but there is still a long way to go. The increase in this coverage depends on reaching adolescents who are younger, less educated, black skin color, living without a partner, multiparous and smokers.

Resumo Objetivos: caracterizar o estado nutricional de crianças indígenas menores de cinco anos, de comunidades rurais na região do Alto Solimões, habitada por sete etnias, com base em dados de dezembro de 2013. Métodos: foram extraídos dos formulários do SISVAN Indígena dados de peso e estatura, coletados em 2013, de 7.520 crianças (86,0% das crianças estimadas nesta faixa etária). Foram calculados os índices estatura-para-idade (E/I), peso-para-idade (P/I), peso-para-estatura (P/E) e índice de massa corporal para idade (IMC/I). Curvas de referência para crescimento propostas pela Organização Mundial da Saúde foram utilizadas para calcular escores z. Resultados: o índice estatura-para-idade (E/I) apresentou os menores valores médios de escore z, chegando a -1,95 nas crianças entre 36 e 60 meses. Os valores médios do escore z do índice peso-para-idade (P/I) também permaneceram abaixo de zero. Os valores médios do escore z para os índices P/E e índice de massa corporal para idade (IMC/I) mantiveram-se ligeiramente acima de zero, atingindo valor máximo de 0,5. Do total de crianças, 45,7% apresentaram baixa E/I, 9,6%, baixo P/I, 4,5% baixo P/E e 10,7% de excesso de peso de acordo com o IMC/I. Conclusão: em 2013 a desnutrição persistia como um importante agravo à saúde nessas crianças.

ABSTRACT Objective: To estimate the prevalence of adult smokers in the 26 capitals and the Federal District according to the Brazilian Deprivation Index (Índice Brasileiro de Privação – IBP). Methods: Dataset on smoking were obtained from the Surveillance of Risk and Protective Factors for Noncommunicable Diseases by Survey (Vigitel) system for the 26 capitals and the Federal District, in the period from 2010 to 2013. The IBP classifies the census sectors according to indicators such as: income less than ½ minimum wage, illiterate population and without sanitary sewage. In the North and Northeast regions, the census sectors were grouped into four categories (low, medium, high and very high deprivation) and in the South, Southeast and Midwest regions into three (low, medium and high deprivation). Prevalence estimates of adult smokers were obtained using the indirect estimation method in small areas. To calculate the prevalence ratios, Poisson models are used. Results: The positive association between prevalence and deprivation of census sector categories was found in 16 (59.3%) of the 27 cities. In nine (33.3%) cities, the sectors with the greatest deprivation had a higher prevalence of smokers when compared to those with the least deprivation, and in two (7.4%) there were no differences. In Aracaju, Belém, Fortaleza, João Pessoa, Macapá and Salvador, the prevalence of adult smokers was three times higher in the group of sectors with greater deprivation compared to those with less deprivation. Conclusion: Sectors with greater social deprivation had a higher prevalence of smoking, compared with less deprivation, pointing to social inequalities.

ABSTRACT Objective: To analyze the coverage of MMR and polio vaccines, the temporal trend and spatial dependence, in children up to one year of age in Brazil, between 2011 and 2021. Methods: Ecological study with secondary data on vaccination coverage rates, made available by the National Immunization Program Information System. Trend analysis was carried out using the joinpoint method, according to geographic regions, estimating the annual percentage change (APC) and its respective confidence interval (95%CI). Choropleth maps of distribution by health region were constructed and, subsequently, the spatial dependence was verified using Moran's statistics. Results: Between 2011 and 2021, vaccination coverage declined in Brazil, both for MMR (APC: −6.4%; 95%CI −9.0; −3.8) and for poliomyelitis (APC: −4. 5%; 95%CI −5.5; −3.6). There was a decline in coverage of both vaccines in all geographic regions over the years of the study, except in the South and Midwest for the MMR vaccine. Since 2015, few health regions in the country have achieved adequate vaccination coverage (≥95.0% to <120.0%). The North and Northeast health regions showed low-low clusters in the univariate analysis for both immunobiological. Conclusions: It is urgent to consider studies like this one for the planning of more effective strategies for immunizing children, especially in areas with higher falls. In this way, barriers to access to immunization can be broken, given Brazil's heterogeneity, and access to reliable information that increases confidence in vaccine efficacy can be expanded.
