RESUMO

BACKGROUND: The world prevalence of people with dementia is increasing. Most of the care received by people with dementia is provided by family caregivers, and this prolonged activity has a significant impact on caregivers' levels of depression. Stressors and frequency of leisure are known predictors of caregivers' depressive levels. The longitudinal impact of caregivers' ambivalent and guilt feelings is unknown. METHODS: Participants were 177 family caregivers of relatives with dementia who were assessed three times during a 2-year period. In addition to demographic variables, psychological symptoms of the dementias, and frequency of leisure activities, caregivers' ambivalent feelings, guilt, and depressive symptoms were measured. The longitudinal association of changes in these variables with changes in caregivers' depressive symptoms over time was assessed using mixed linear models. RESULTS: Changes over time in the assessed variables predicted 48.05% of variance of changes over time in depressive symptoms. Even when variables strongly associated with increased depressive symptoms were controlled (lower caregivers' age and educational level, higher reaction to BPSD, and lower leisure activities), increases in ambivalence and guilt contributed to an increase of 9.22% of the variance of changes depressive symptoms over a 2-year period. The effects of ambivalent feelings on depression are indirect, mediated by guilt feelings. Cessation of caregiving do not seem to alter these findings. CONCLUSIONS: Caregivers' ambivalent and guilt feelings are significant predictors of caregivers' mental health. Caregivers may significantly benefit from early detection of ambivalent and guilt feelings and preventive strategies targeting triggers associated with ambivalent and guilt symptoms.

RESUMO

The textile industry generates highly contaminated wastewater. It severely threatens local ecosystems without proper treatment, significantly diminishing biodiversity near the discharge point. With rapid growth rates, microalgae offer an effective solution to mitigate the environmental impact of textile wastewater, and the generated biomass can be valorised. This study sets out to achieve two primary objectives: (i) to assess the removal of pollutants by Chlorella vulgaris from two distinct real textile wastewaters (without dilution) and (ii) to evaluate microalgal biomass composition for further valorisation (in a circular economy approach). Microalgae grew successfully with growth rates ranging from 0.234 ± 0.005 to 0.290 ± 0.003 d-1 and average productivities ranging from 78 ± 3 to 112.39 ± 0.07 mgDW L-1 d-1. All cultures demonstrated a significant reduction in nutrient concentrations for values below the legal limits for discharge, except for COD in effluent 2. Furthermore, the pigment concentration in the culture increased during textile effluent treatment, presenting a distinct advantage over conventional ones due to the economic value of produced biomass and pigments. This study underscores the promise of microalgae in textile wastewater treatment and provides valuable insights into their role in addressing the environmental challenges the textile industry poses.

RESUMO

OBJECTIVES: Perceived control is a relevant variable for understanding middle and older adults' mental health. The Perceived Control Scale has two dimensions, Perceived Constraints on Personal Control and Perceived Mastery, and is a widely used instrument for assessing perceived control in adults. The aim of this study was to analyze the psychometric properties of the Spanish version of the Perceived Control Scale with data from two different studies. METHOD: In Study 1, 348 older adults between 60 and 92 years old were assessed through face-to-face assessments. In Study 2, 334 adults between 40 and 90 years completed an online survey. Perceived control, self-perceptions of aging, and anxiety and depressive symptomatology were assessed. An exploratory (Study 1) and confirmatory (Study 2) factor analysis of the Perceived Control Scale were performed, and reliability and its relationship with the other assessed variables were evaluated. RESULTS: Results from parallel, exploratory, and confirmatory factor analyses suggested that the Spanish version of the Perceived Control Scale has a bidimensional structure: Perceived Constraints on Personal Control and Perceived Mastery. Good internal consistency was found for the scale in both samples. The results revealed negative and significant associations with negative self-perceptions of aging, and anxiety and depressive symptomatology. CONCLUSION: The Spanish version of the Perceived Control Scale shows good psychometric properties which endorse its use with middle-aged and older adults assessed either face-to-face or through online surveys.

RESUMO

The comprehensive evaluation and validation of mathematical models for microalgal growth dynamics are essential for improving cultivation efficiency and optimising photobioreactor design. A considerable gap in comprehending the relation between microalgal growth, light intensity and biomass concentration arises since many studies focus solely on associating one of these factors. This paper compares microalgal growth kinetic models, specifically focusing on the combined impact of light intensity and biomass concentration. Considering a dataset (experimental results and literature values) concerning Chlorella vulgaris, nine kinetic models were assessed. Bannister and Grima models presented the best fitting performance to experimental data (RMSE ≤ 0.050 d-1; R2≥0.804; d2≥0.943). Cultivation conditions conducting photoinhibition were identified in some kinetic models. After testing these models on independent datasets, Bannister and Grima models presented superior predictive performance (RMSE = 0.022-0.023 d-1; R2 = 0.878-0.884; d2: 0.976-0.975). The models provide valuable tools for predicting microalgal growth and optimising operational parameters, reducing the need for time-consuming and costly experiments.

RESUMO

Mastitis is an inflammatory disease in dairy cows, causing economic losses and reducing animal welfare. In order to contribute for the discovery of early and noninvasive indicators, our objective was to determine the effects of a lipopolysaccharide (LPS) challenge on the microRNA profile (miRNome) of milk fat, using microarray analyses in cows. Cows were fed a lactation diet at ad libitum intake (n = 6). At 27 ± 3 days in milk, cows were injected with 50 µg of LPS Escherichia coli in one healthy rear mammary quarter. Milk samples were collected just before LPS challenge (LPS-) and 6.5 h after LPS challenge (LPS +) from the same cows. Microarray analysis was performed using customized 8 × 60 K ruminant miRNA microarrays to compare LPS- to LPS + miRNome. In silico functional analyses were performed using OmicsNet and Mienturnet software. MiRNome comparison between LPS- and LPS + identified 37 differentially abundant miRNAs (q-value ≤ 0.05). The predicted target genes of the 37 differentially abundant miRNAs are mostly involved in cell life including apoptosis, cell cycle, proliferation and differentiation and in gene expression processes. MiRNome analyses suggest that miRNAs profile is related to the inflammation response of the mammary gland. In conclusion, we demonstrated that milk fat might be an easy and rapid source of miRNAs that are potential indicators of early mastitis in cows.

RESUMO

BACKGROUND: Chronic low back pain (LBP) is defined as pain lasting longer than 3 months and is one of the conditions with the most significant social impact. Treatment is complex and includes proliferative agents used in prolotherapy. The mechanism is not known, but osmotic agents (hypertonic solutions of dextrose or glucose) cause cellular rupture and an inflammatory response that releases cytokines and growth factors that lead to scarring and reinnervation. METHODS: Patients with chronic LBP (>12 weeks) who were non-traumatic and unresponsive to at least 1 month of physical therapy were selected. All patients were followed up at a return visit at 1, 3, and 6 months for pain assessment using validated pain questionnaires and scales. RESULTS: Nineteen patients were included in the conservative group and 19 in the glucose group, with the majority being women (57.9%). The patients were between 47 and 59 years of age (39.5%), mixed race (76.33%), married or in a committed relationship (73.7%), and had completed the study for 5.2 years. Overall mean body mass index was 27.3 ± 4.4 kg/m 2 and was higher in the conservative group (28.0 ± 4.7 kg/m 2 ). The groups showed differences in Visual Analog Scale scores, with median and amplitude values close to each other between the time points evaluated and increasing values in the glucose group, which had significantly higher values for this scale at the third evaluation ( P = .031). When comparing the Rolland-Morris scale scores between the groups, there was a significant difference only in the 3-m assessment ( P = .021). In the follow-up assessment, both groups showed significant improvement between T0 and the other assessment time points ( P < .05) in all evaluations. CONCLUSION: Both groups significantly improved on the evaluated scales during follow-up. Overall, no effects were attributable to the glucose components or the prolotherapy protocol.

RESUMO

Objectives: To examine the cross-national associations between familism and self-efficacy dimensions, and levels of burden and depression. Methods: Sociodemographic, familism, self-efficacy, depressive symptoms, and burden variables were measured in 349 dementia family caregivers from the US and Spain. Results: US sample: greater support from family was positively related to self-efficacy for obtaining respite and self-efficacy for controlling upsetting thoughts and behaviors. Both self-efficacy constructs were negatively related to depression. Similar findings were obtained for burden. Spanish sample: higher scores on family as referents were associated with lower scores on self-efficacy for obtaining respite; lower scores on self-efficacy for obtaining respite were associated with higher depressive symptomatology. Discussion: Study findings suggest that a significant interplay exists between the various facets of familism and self-efficacy, leading to differential caregiving outcomes. Unique cultural contexts and values derived from each country may exert distinct influences on how the caregiving role is perceived and appraised.

RESUMO

Microalgae are a promising feedstock for bioethanol production, essentially due to their high growth rates and absence of lignin. Hydrolysis-where the monosaccharides are released for further fermentation-is considered a critical step, and its optimization is advised for each raw material. The present study focuses on the thermal acid hydrolysis (with sulfuric acid) of Aurantiochytrium sp. through a response surface methodology (RSM), studying the effect of acid concentration, hydrolysis time and biomass/acid ratio on both sugar concentration of the hydrolysate and biomass conversion yield. Preliminary studies allowed to establish the range of the variables to be optimized. The obtained models predicted a maximum sugar concentration (18.05 g/L; R2 = 0.990) after 90 min of hydrolysis, using 15% (w/v) biomass/acid ratio and sulfuric acid at 3.5% (v/v), whereas the maximum conversion yield (12.86 g/100 g; R2 = 0.876) was obtained using 9.3% (w/v) biomass/acid ratio, maintaining the other parameters. Model outputs indicate that the biomass/acid ratio and time are the most influential parameters on the sugar concentration and yield models, respectively. The study allowed to obtain a predictive model that is very well adjusted to the experimental data to find the best saccharification conditions for the Aurantiochytrium sp. microalgae.

RESUMO

Alterations of the glycosylation machinery are common events in cancer, leading to the synthesis of aberrant glycan structures by tumor cells. Extracellular vesicles (EVs) play a modulatory role in cancer communication and progression, and interestingly, several tumor-associated glycans have already been identified in cancer EVs. Nevertheless, the impact of 3D tumor architecture in the selective packaging of cellular glycans into EVs has never been addressed. In this work, the capacity of gastric cancer cell lines with differential glycosylation is evaluated in producing and releasing EVs when cultured under conventional 2D monolayer or in 3D culture conditions. Furthermore, the proteomic content is identified and specific glycans are studied in the EVs produced by these cells, upon differential spatial organization. Here, it is observed that although the proteome of the analyzed EVs is mostly conserved, an EV differential packaging of specific proteins and glycans is found. In addition, protein-protein interaction and pathway analysis reveal individual signatures on the EVs released by 2D- and 3D-cultured cells, suggesting distinct biological functions. These protein signatures also show a correlation with clinical data. Overall, this data highlight the importance of tumor cellular architecture when assessing the cancer-EV cargo and its biological role.

RESUMO

Being married has been associated with a better attitude to aging and a buffer against stressful situations, factors that influence mental health. The study analyzes the role of self-perceptions of aging and stress related to the COVID–19 pandemic in the association between marital satisfaction and participants’ mental health. 246 people older than 40 years in a marital/partner relationship were assessed. A path analysis was tested, where self-perceptions of aging and stress from the COVID–19 situation were proposed as mechanisms of action in the association between marital satisfaction and anxious and depressive symptoms. Marital satisfaction, self-perceptions of aging, and stress associated with the COVID–19 pandemic significantly contributed to the model and explained 31% of the variance in participants´ anxious symptomatology, and 42% of the variance in depressive symptomatology. The indirect path of self-perceptions of aging and stress associated with the COVID–19 pandemic in the link between marital satisfaction and anxious and depressive symptoms was statistically significant for both outcome variables. The findings of this study suggest that lower perceived marital satisfaction is associated with higher levels of negative self-perceptions of aging and with higher anxiety and depressive symptoms. Public significance statements: This study suggests that higher marital satisfaction may be a buffer for negative self-perception of aging, and both factors are related with experiencing less stress from COVID–19. These links are associated with less anxious and depressive symptoms. (AU)

RESUMO

Microalgae have remarkable potential for wastewater bioremediation since they can efficiently uptake nitrogen and phosphorus in a sustainable and environmentally friendly treatment system. However, wastewater composition greatly depends on its source and has a significant seasonal variability. This study aimed to evaluate the impact of different N:P molar ratios on the growth of Chlorella vulgaris and nutrient removal from synthetic wastewater. Furthermore, artificial neural network (ANN) threshold models, optimised by genetic algorithms (GAs), were used to model biomass productivity (BP) and nitrogen/phosphorus removal rates (RRN/RRP). The impact of various inputs culture variables on these parameters was evaluated. Microalgal growth was not nutrient limited since the average biomass productivities and specific growth rates were similar between the experiments. Nutrient removal efficiencies/rates reached 92.0 ± 0.6%/6.15 ± 0.01 mgN L-1 d-1 for nitrogen and 98.2 ± 0.2%/0.92 ± 0.03 mgP L-1 d-1 for phosphorus. Low nitrogen concentration limited phosphorus uptake for low N:P ratios (e.g., 2 and 3, yielding 36 ± 2 mgDW mgP-1 and 39 ± 3 mgDW mgP-1, respectively), while low phosphorus concentration limited nitrogen uptake with high ratios (e.g., 66 and 67, yielding 9.0 ± 0.4 mgDW mgN-1 and 8.8 ± 0.3 mgDW mgN-1, respectively). ANN models showed a high fitting performance, with coefficients of determination of 0.951, 0.800, and 0.793 for BP, RRN, and RRP, respectively. In summary, this study demonstrated that microalgae could successfully grow and adapt to N:P molar ratios between 2 and 67, but the nutrient uptake was impacted by these variations, especially for the lowest and highest N:P molar ratios. Furthermore, GA-ANN models demonstrated to be relevant tools for microalgal growth modelling and control. Their high fitting performance in characterising this biological system can contribute to reducing the experimental effort for culture monitoring (human resources and consumables), thus decreasing the costs of microalgae production.

RESUMO

Water is the most valuable resource on the planet. However, massive anthropogenic activities generate threatening levels of biological, organic, and inorganic pollutants that are not efficiently removed in conventional wastewater treatment systems. High levels of conventional pollutants (carbon, nitrogen, and phosphorus), emerging chemical contaminants such as antibiotics, and pathogens (namely antibiotic-resistant ones and related genes) jeopardize ecosystems and human health. Conventional wastewater treatment systems entail several environmental issues: (i) high energy consumption; (ii) high CO2 emissions; and (iii) the use of chemicals or the generation of harmful by-products. Hence, the use of microalgal systems (entailing one or several microalgae species, and in consortium with bacteria) as environmental agents towards wastewater treatment has been seen as an environmentally friendly solution to remove conventional pollutants, antibiotics, coliforms and antibiotic resistance genes. In recent years, several authors have evaluated the use of microalgal systems for the treatment of different types of wastewater, such as agricultural, municipal, and industrial. Generally, microalgal systems can provide high removal efficiencies of: (i) conventional pollutants, up to 99%, 99%, and 90% of total nitrogen, total phosphorus, and/or organic carbon, respectively, through uptake mechanisms, and (ii) antibiotics frequently found in wastewaters, such as sulfamethoxazole, ciprofloxacin, trimethoprim and azithromycin at 86%, 65%, 42% and 93%, respectively, through the most desirable microalgal mechanism, biodegradation. Although pathogens removal by microalgal species is complex and very strain-specific, it is also possible to attain total coliform and Escherichia coli removal of 99.4% and 98.6%, respectively. However, microalgal systems' effectiveness strongly relies on biotic and abiotic conditions, thus the selection of operational conditions is critical. While the combination of selected species (microalgae and bacteria), ratios and inoculum concentration allow the efficient removal of conventional pollutants and generation of high amounts of biomass (that can be further converted into valuable products such as biofuels and biofertilisers), abiotic factors such as pH, hydraulic retention time, light intensity and CO2/O2 supply also have a crucial role in conventional pollutants and antibiotics removal, and wastewater disinfection. However, some rationale must be considered according to the purpose. While alkaline pH induces the hydrolysis of some antibiotics and the removal of faecal coliforms, it also decreases phosphates solubility and induces the formation of ammonium from ammonia. Also, while CO2 supply increases the removal of E. coli and Pseudomonas aeruginosa, as well as the microalgal growth (and thus the conventional pollutants uptake), it decreases Enterococcus faecalis removal. Therefore, this review aims to provide a critical review of recent studies towards the application of microalgal systems for the efficient removal of conventional pollutants, antibiotics, and pathogens; discussing the feasibility, highlighting the advantages and challenges of the implementation of such process, and presenting current case-studies of different applications of microalgal systems.

RESUMO

The study assessed gender differences in the associations between familism dimensions, dysfunctional thoughts, and resource and outcome variables in 190 Spanish dementia family caregivers. A theoretical model was tested through path analysis, obtaining an excellent fit of the model to the data. Higher scores in the familial obligations dimension were associated with lower self-efficacy for self-care and obtaining respite and leisure frequency, and higher anxious and depressive feelings, in female caregivers only. Significant between-gender differences were obtained, suggesting that female caregivers holding strong familistic values are more vulnerable to the negative consequences of caregiving compared to male caregivers.

RESUMO

OBJECTIVES: Behavioral and psychological symptoms of dementia (BPSD) are considered to cause ambivalent feelings in caregivers that may contribute to understanding their depressive symptoms. Transnational research is needed in order to increase our knowledge about the cross-cultural equivalence of theoretical models to understand caregivers' mental health. The aim of this study was to cross-culturally analyze the association between BPSD, ambivalent feelings and depressive symptoms in two samples of family caregivers of people with dementia from Spain and the UK. METHODS: Participants in this study were 432 caregivers who completed measures of BPSD, ambivalent feelings and depressive symptoms. The association between the assessed variables was tested through path-analysis, with differences between countries tested through multigroup analysis. RESULTS: The results suggest that the influence of BPSD on caregivers' depressive symptoms is indirect, through ambivalent feelings. The observed associations were equivalent between countries and explained a significant percentage of the variance of depressive symptoms. CONCLUSION: The findings of this study provide, for the first time, evidence of equivalent cross-cultural paths analyzing the role of ambivalent feelings for understanding caregivers' depressive symptoms. The practical implications of these results are discussed.

RESUMO

Introdução: As síndromes coronarianas agudas decorrem de ruptura de placa coronariana com formação de trombos, embolização e obstrução, dependendo do nível de obstrução, podemos ter infartos e anginas e a nível eletrocardiográfico podemos ter ou não o supra desnivelamento do segmento ST. Para o correto diagnóstico e melhor prognóstico é importante acompanhar suas manifestações clínicas e avaliar as alterações eletrocardiográficas. Objetivo: Estudar uso do eletrocardiograma padrão de 12 derivações, para diagnóstico da oclusão coronariana aguda: uma nova abordagem eletrocardiográfica das síndromes coronarianas. Método: Estudo de revisão integrativa, com dados secundários da Biblioteca Virtual em Saúde (BVS), base eletrônica de dados da Literatura Latino ­ Americana e do Caribe em Ciências da Saúde (Lilacs) e da biblioteca digital Scientific Electronic Library Online (Scielo). Resultados: Descreveu-se 7 achados eletrocardiográficos sugestivos de oclusão coronariana aguda: padrões como os De Winter, Wellens, IAM posterior, distorção final do QRS, Critérios de Sgarbossa- Smith para IAM associado a BRE ou ritmo de marca-passo ventricular, ondas T's hiperagudas e fórmulas matemáticas para diagnóstico da oclusão da descendente anterior. Conclusão: Embora a abordagem que se vale de tais achados no ECG seja mais acurada na detecção da oclusão coronariana aguda do que os critérios milimétricos do segmento ST, essa nova abordagem precisa de mais estudos para avaliação de seu real poder diagnóstico.


Introduction: As acute coronary syndromes due to coronary plaque rupture, with thrombus formation, embolization and obstruction, depending on the degree of obstruction, we may have infarction and angina at the electrocardiographic level, we may have an unevenness or overdevelopment of the ST interval. For a correct diagnosis and prognosis, it is important to monitor its clinical manifestations and assess electrocardiographic changes. Objective: To study the use of a standard 12- lead electrocardiogram for the diagnosis of acute coronary occlusion: a new electrocardiographic approach to coronary syndromes. Method: Integrative review study, secondary data from the Virtual Health Library (VHL), electronic database of the Latin American and Caribbean Literature on Health Sciences (Lilacs) and the Scientific Electronic Library Online (Scielo) digital library. Results: Seven electrocardiographic findings suggestive of acute coronary occlusion were described: patterns such as De Winter, Wellen, posterior AMI, terminal QRS distortion, Sgarbossa-Smith criteria for AMI associated with LBBB or ventricular paced rhythm, hyperacute T waves, and mathematical formulas for diagnosing anterior descending occlusion. Conclusion: Although the approach that makes use of such ECG findings is more accurate in detecting acute coronary occlusion than the millimeter ST-segment criteria, this new approach needs further studies to assess its real diagnostic power.


Introducción: Como síndromes coronarios agudos debidos a rotura de placa coronaria, con formación de trombo, embolización y obstrucción, dependiendo del grado de obstrucción, podemos tener infarto y angina a nivel electrocardiográfico, podemos tener un desnivel o sobredesarrollo del intervalo ST. Para un correcto diagnóstico y pronóstico es importante monitorizar sus manifestaciones clínicas y valorar los cambios electrocardiográficos. Objetivo: Estudiar el uso de un electrocardiograma estándar de 12 derivaciones para el diagnóstico de la oclusión coronaria aguda: una nueva aproximación electrocardiográfica a los síndromes coronarios. Método: Estudio de revisión integradora, datos secundarios de la Biblioteca Virtual en Salud (BVS), base de datos electrónica de la Literatura Latinoamericana y del Caribe en Ciencias de la Salud (Lilacs) y de la biblioteca digital Scientific Electronic Library Online (Scielo). Resultados: Se describieron siete hallazgos electrocardiográficos sugestivos de oclusión coronaria aguda: patrones como De Winter, Wellen, IAM posterior, distorsión terminal del QRS, criterios de Sgarbossa-Smith para IAM asociado a BRIHH o ritmo ventricular estimulado, ondas T hiperagudas y fórmulas matemáticas para el diagnóstico de oclusión de la descendente anterior. Conclusiones: Aunque el enfoque que hace uso de dichos hallazgos ECG es más preciso en la detección de la oclusión coronaria aguda que los criterios milimétricos del segmento ST, este nuevo enfoque necesita más estudios para evaluar su poder diagnóstico real.

RESUMO

Introdução: Entre o início da epidemia do HIV na década de 1980 até 2018, houve cerca de 32 milhões de óbitos e no mundo existem aproximadamente 37,9 milhões de pessoas viviam com HIV e AIDS. Assim, mesmo com advento da TARV, as pessoas vivendo com HIV/AIDS permanecem sujeitas a redução na qualidade de vida, sendo que dentre esses fatores a coinfecção por Tuberculose se demonstra a principal responsável pela alteração de prognóstico. Desta forma o presente estudo busca estabelecer um panorama epidemiológico das pessoas vivendo com HIV/ AIDS e a sua principal coinfecção no Estado do Maranhão. Metodologia: Trata-se de um estudo epidemiológico descritivo retrospectivo, de abordagem quantitativa que apresenta o perfil das pessoas que vivem com HIV/AIDS, bem como, a principal coinfecção, no período de 2009 a 2018 no Maranhão. Resultados: No período de 2009 a 2018 foram notificados 7691 casos de AIDS no Maranhão, sendo a maioria composta por indivíduos de 20 a 49 anos, do sexo masculino, cor parda e com escolaridade entre a 1ª serie e o ensino fundamental completo, via de transmissão heterossexual e com maior tendência a coinfecção por Tuberculose nos últimos anos da amostra e nos casos de uso de TARV. Conclusão: O Panorama obtido propõe uma maior necessidade de intervenção e conscientização da necessidade de códons, além de maior rastreio de indivíduos no uso da TARV. Embora observada forte redução nas notificações em 2018, há a necessidade de cautela, principalmente pelo retrato da epidemia em regiões com similaridade sócio demográfica.


Introduction: Between the beginning of the HIV epidemic in the 1980s until 2018, there were about 32 million deaths and in the world there are approximately 37.9 million people living with HIV and AIDS. Thus, even with the advent of ART, people living with HIV/AIDS remain subject to reduced quality of life, and among these factors, co-infection with tuberculosis proves to be the main responsible for the change in prognosis. Thus, the present study seeks to establish an epidemiological panorama of people living with HIV/AIDS and their main co-infection in the state of Maranhão. Methodology: This is a retrospective descriptive epidemiological study, of quantitative approach that presents the profile of people living with HIV/AIDS, as well as, the main coinfection, in the period from 2009 to 2018 in Maranhão. Results: In the period from 2009 to 2018, 7691 cases of AIDS were notified in Maranhão, being the majority composed of individuals aged 20 to 49 years, male, brown color and with education between 1st grade and complete elementary school, heterosexual transmission route and with a greater tendency to coinfection by Tuberculosis in the last years of the sample and in cases of ART use. Conclusion: The Panorama obtained proposes a greater need for intervention and awareness of the need for codons, in addition to greater screening of individuals on ART use. Although observed a strong reduction in notifications in 2018, there is a need for caution, mainly because of the epidemic's portrayal in regions with socio demographic similarity.


Introducción: Entre el inicio de la epidemia del VIH en la década de 1980 hasta 2018, hubo cerca de 32 millones de muertes y en el mundo hay aproximadamente 37,9 millones de personas que viven con el VIH y el SIDA. Así, incluso con el advenimiento de la terapia antirretroviral, las personas que viven con VIH/SIDA siguen estando sujetas a la reducción de la calidad de vida, y entre estos factores, la coinfección con tuberculosis resulta ser el principal responsable del cambio en el pronóstico. Así, el presente estudio busca establecer un panorama epidemiológico de las personas que viven con VIH/SIDA y sus principales coinfecciones en el estado de Maranhão. Metodología: Se trata de un estudio epidemiológico descriptivo retrospectivo, de abordaje cuantitativo que presenta el perfil de las personas que viven con VIH/SIDA, así como, la principal coinfección, en el período de 2009 a 2018 en Maranhão. Resultados: En el período de 2009 a 2018, fueron notificados 7691 casos de SIDA en Maranhão, siendo la mayoría compuesta por individuos de 20 a 49 años, de sexo masculino, color castaño y con escolaridad entre 1º grado y primaria completa, vía de transmisión heterosexual y con mayor tendencia a la coinfección por Tuberculosis en los últimos años de la muestra y en los casos de uso de TAR. Conclusiones: El Panorama obtenido propone una mayor necesidad de intervención y concienciación de la necesidad de codones, además de un mayor cribado de los individuos en uso de TAR. A pesar de observarse una fuerte reducción de notificaciones en 2018, es necesario ser cautelosos, principalmente por el retrato de la epidemia en regiones con similitud socio demográfica.

RESUMO

Com grande impacto social por alta mortalidade e morbidade no Brasil e no Mundo, o AVC continua em destaque dentre as Doenças Crônicas Não transmissíveis. Visando oferecer subsídios técnico-científicos sobre o perfil epidemiológico desta patologia no Nordeste, este artigo consiste em um estudo de corte transversal, quantitativo, epidemiológico, de série temporal, entre os anos de 2015 a 2019, tendo por base os dados disponibilizados na plataforma DATASUS. Evidenciou-se que o ano de 2019 foi o ano com maior número de internações por esta patologia, predominando em homens. No entanto, as mulheres tiveram mais óbitos. A raça mais acometida foi a parda, com mais de 82% das internações e mais de 83% dos óbitos. Os óbitos ocorreram em todas as faixas etárias, predominando nos mais idosos. O Estado com maior quantitativo de óbitos foi a Bahia, também o mais populoso do estudo. O perfil epidemiológico geral, do paciente acometido por AVC na região Nordeste do Brasil no período avaliado, foi, homem, com idade mais avançada (a partir de 60 anos), pardo, permanecendo cerca de 7,8 dias internados. O custo total desse período, com internações por AVC, foi de R$278.874.426.3, certamente, um custo bastante oneroso ao nosso sistema de saúde. As unidades federativas com maior acometimento são também as mais populosas. Percebendo-se que, por se tratar de uma doença prevenível, com graves sequelas e que causam grandes prejuízos pessoais, sociais e econômicos, torna-se relevante que o sistema público de saúde adote rigorosas medidas para sua prevenção.


With a great social impact due to high mortality and morbidity in Brazil and the world, stroke continues to be highlighted among Chronic Non-communicable Diseases. Aiming to offer technical-scientific support on the epidemiological profile of this pathology in the Northeast, this article consists of a cross-sectional, quantitative, epidemiological, time series study, between the years 2015 and 2019, based on data available on the DATASUS platform . It was evident that 2019 was the year with the highest number of hospitalizations for this pathology, predominantly in men. However, women had more deaths. The most affected race was the mixed race, with more than 82% of hospitalizations and more than 83% of deaths. Deaths occurred in all age groups, predominantly among the elderly. The State with the highest number of deaths was Bahia, also the most populous in the study. The general epidemiological profile of the patient affected by stroke in the Northeast region of Brazil during the period evaluated was male, older (60 years and older), mixed race, and remained hospitalized for approximately 7.8 days. The total cost of this period, with hospitalizations for stroke, was R$278,874,426.3, certainly a very costly cost to our health system. The federative units most affected are also the most populous. Realizing that, as it is a preventable disease, with serious consequences and causing great personal, social and economic losses, it is important that the public health system adopts strict measures for its prevention.
