Novel Fe3O4 Nanoparticles with Bioactive Glass-Naproxen Coating: Synthesis, Characterization, and In Vitro Evaluation of Bioactivity.

Immune response to biomaterials, which is intimately related to their surface properties, can produce chronic inflammation and fibrosis, leading to implant failure. This study investigated the development of magnetic nanoparticles coated with silica and incorporating the anti-inflammatory drug naproxen, aimed at multifunctional biomedical applications. The synthesized nanoparticles were characterized using various techniques that confirmed the presence of magnetite and the formation of a silica-rich bioactive glass (BG) layer. In vitro studies demonstrated that the nanoparticles exhibited bioactive properties, forming an apatite surface layer when immersed in simulated body fluid, and biocompatibility with bone cells, with good viability and alkaline phosphatase activity. Naproxen, either free or encapsulated, reduced nitric oxide production, an inflammatory marker, while the BG coating alone did not show anti-inflammatory effects in this study. Overall, the magnetic nanoparticles coated with BG and naproxen showed promise for biomedical applications, especially anti-inflammatory activity in macrophages and in the bone field, due to their biocompatibility, bioactivity, and osteogenic potential.

Roles of the Red List of Ecosystems in the Kunming-Montreal Global Biodiversity Framework.

The Kunming-Montreal Global Biodiversity Framework (GBF) of the UN Convention on Biological Diversity set the agenda for global aspirations and action to reverse biodiversity loss. The GBF includes an explicit goal for maintaining and restoring biodiversity, encompassing ecosystems, species and genetic diversity (goal A), targets for ecosystem protection and restoration and headline indicators to track progress and guide action1. One of the headline indicators is the Red List of Ecosystems2, the global standard for ecosystem risk assessment. The Red List of Ecosystems provides a systematic framework for collating, analysing and synthesizing data on ecosystems, including their distribution, integrity and risk of collapse3. Here, we examine how it can contribute to implementing the GBF, as well as monitoring progress. We find that the Red List of Ecosystems provides common theory and practical data, while fostering collaboration, cross-sector cooperation and knowledge sharing, with important roles in 16 of the 23 targets. In particular, ecosystem maps, descriptions and risk categories are key to spatial planning for halting loss, restoration and protection (targets 1, 2 and 3). The Red List of Ecosystems is therefore well-placed to aid Parties to the GBF as they assess, plan and act to achieve the targets and goals. We outline future work to further strengthen this potential and improve biodiversity outcomes, including expanding spatial coverage of Red List of Ecosystems assessments and partnerships between practitioners, policy-makers and scientists.

Anti-Trypanosoma cruzi Potential of Vestitol Isolated from Lyophilized Red Propolis.

Chagas disease (CD) is a worldwide public health problem, and the drugs available for its treatment have severe limitations. Red propolis is a natural extract known for its high content of phenolic compounds and for having activity against T. cruzi. The aim of this study was to investigate the trypanocidal potential of red propolis to isolate, identify, and indicate the mode of action of the bioactive compounds. The results revealed that the total phenolic content was 15.4 mg GAE/g, and flavonoids were 7.2 mg QE/g. The extract was fractionated through liquid-liquid partitioning, and the trypanocidal potential of the samples was evaluated using the epimastigote forms of the Y strain of T. cruzi. In this process, one compound was characterized by MS, 1H, and 13C NMR and identified as vestitol. Cytotoxicity was evaluated employing MRC-5 fibroblasts and H9C2 cardiomyocytes, showing cytotoxic concentrations above 15.62 µg/mL and 31.25 µg/mL, respectively. In silico analyses were applied, and the data suggested that the substance had a membrane-permeation-enhancing effect, which was confirmed through an in vitro assay. Finally, a molecular docking analysis revealed a higher affinity of vestitol with farnesyl diphosphate synthase (FPPS). The identified isoflavan appears to be a promising lead compound for further development to treat Chagas disease.

Psychological Status of the Participants in Alzheimer's Prevention Initiative Autosomal Dominant Alzheimer's Disease Colombia.

BACKGROUND: The SARS-CoV2 global pandemic impacted participants in the Alzheimer's Prevention Initiative (API) Autosomal Dominant Alzheimer's Disease (ADAD) clinical trial, who faced three stressors: 1) fear of developing dementia; 2) concerns about missing treatment; and 3) risk of SARS-CoV2 infection. OBJECTIVE: To describe the frequency of psychological disorders among the participants of the API ADAD Colombia clinical study, treated by a holistic mental health team during the COVID-19 pandemic. The extent of use of mental health team services was explored considering different risk factors, and users and non-users of these services were compared. METHODS: Participants had free and optional access to psychology and psychiatry services, outside of the study protocol. Descriptive statistics was used to analyze the frequency of the mental health difficulties. A multivariable logistic regression model has been used to assess associations with using this program. RESULTS: 66 participants were treated by the Mental Health Team from March 1, 2020, to December 31, 2020. Before and after the start of the pandemic, the most common psychological problems were anxiety (36.4% before, 63.6% after) and depression (34.8% before, 37.9% after). 70% of users assisted by psychology and 81.6% of those assisted by psychiatry felt that the services were useful for them. Female sex, depression, and anxiety before the pandemic were positively associated with being assisted by either psychology or psychiatry, while the association with hyperlipidemia was negative. CONCLUSIONS: A holistic mental health program, carried out in the context of a study, could mitigate psychopathology during pandemics such as COVID-19.

Controlled Release and Cell Viability of Ketoconazole Incorporated in PEG 4000 Derivatives.

In recent years, polymeric materials have been gaining prominence in studies of controlled release systems to obtain improvements in drug administration. These systems present several advantages compared with conventional release systems, such as constant maintenance in the blood concentration of a given drug, greater bioavailability, reduction of adverse effects, and fewer dosages required, thus providing a higher patient compliance to treatment. Given the above, the present work aimed to synthesize polymeric matrices derived from polyethylene glycol (PEG) capable of promoting the controlled release of the drug ketoconazole in order to minimize its adverse effects. PEG 4000 is a widely used polymer due to its excellent properties such as hydrophilicity, biocompatibility, and non-toxic effects. In this work, PEG 4000 and derivatives were incorporated with ketoconazole. The morphology of polymeric films was observed by AFM and showed changes on the film organization after drug incorporation. In SEM, it was possible to notice spheres that formed in some incorporated polymers. The zeta potential of PEG 4000 and its derivatives was determined and suggested that the microparticle surfaces showed a low electrostatic charge. Regarding the controlled release, all the incorporated polymers obtained a controlled release profile at pH 7.3. The release kinetics of ketoconazole in the samples of PEG 4000 and its derivatives followed first order for PEG 4000 HYDR INCORP and Higuchi for the other samples. Cytotoxicity was determined and PEG 4000 and its derivatives were not cytotoxic.

Reproductive health syndemics impact retention in care among women living with HIV in Rio de Janeiro, Brazil.

Syndemic psychosocial and reproductive factors affecting women's retention in HIV care remain understudied. We analyzed correlates of non-retention in a cohort of women with HIV in Brazil from 2000‒2015. Participants self-reported exposure to physical/sexual violence, illicit drug use, adolescent pregnancy, or induced abortion. Lifetime history of these psychosocial stressors were used to create a syndemic score based on the presence or absence of these conditions. All dichotomous variables were summed (range 0 to 4), with greater scores indicating more syndemic factors experienced. Logistic regression models identified predictors of non-retention, defined as < 2 HIV viral load or CD4 results within the first year of enrollment. Of 915 women, non-retention was observed for 18%. Prevalence of syndemic factors was adolescent pregnancy (53.2%), physical/sexual violence (38.3%), induced abortion (27.3%), and illicit drug use (17.2%); 41.2% experienced ≥ 2 syndemic conditions. Syndemic scores of 2 and 3 were associated with non-retention, as well as low education, years with HIV and seroprevalent syphilis. Psychosocial and reproductive syndemics can limit women's retention in HIV care. Syphilis infection predicted non-retention and could be explored as a syndemic factor in future studies.

Anti-Inflammatory, Antimicrobial, Antioxidant and Photoprotective Investigation of Red Propolis Extract as Sunscreen Formulation in Polawax Cream.

Many activities have been described for propolis, including, antiviral, antibacterial, antifungal, anti-inflammatory, immunoregulatory, antioxidant and wound healing properties. Recently, propolis has been highlighted due to its potential application in the pharmaceutical and cosmetic industries, motivating a better understanding of its antioxidant and anti-inflammatory activities. Propolis and its main polyphenolic compounds presented high antioxidant activity, and effectiveness as broad spectrum UVB and UVA photoprotection sunscreens. Through a qualitative phytochemical screening, the ethanolic red propolis extracts (EEPV) (70% at room temperature and 70% at a hot temperature) presented a positive result for flavonoids and terpenoids. It presented an antioxidant activity for reducing 50% of DPPH of 17 and 12 µg/mL for extraction at room temperature and at a hot temperature, respectively. The UPLC-QTOF-MS/MS analysis allowed the annotation of 40 substances for EEPV-Heated and 42 substances for EEPV-Room Temperature. The IC50 results of the ABTS scavenging activity was 4.7 µg/mL for both extractions, at room temperature and at a hot temperature. Additionally, we also evaluated the cytotoxic profile of propolis extracts against macrophage (RAW 264.7 cells) and keratinocytes (HaCaT cells), which showed non-cytotoxic doses in cell viability assays even after a long period of exposure. In addition, propolis extracts showed antibacterial activity for Gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis), demonstrating potential biological activity for the creation of formulations aimed at disease control and prevention.

Heating Capacity and Biocompatibility of Hybrid Nanoparticles for Magnetic Hyperthermia Treatment.

Cancer is one of the deadliest diseases worldwide and has been responsible for millions of deaths. However, developing a satisfactory smart multifunctional material combining different strategies to kill cancer cells poses a challenge. This work aims at filling this gap by developing a composite material for cancer treatment through hyperthermia and drug release. With this purpose, magnetic nanoparticles were coated with a polymer matrix consisting of poly (L-co-D,L lactic acid-co-trimethylene carbonate) and a poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) triblock copolymer. High-resolution transmission electron microscopy and selected area electron diffraction confirmed magnetite to be the only iron oxide in the sample. Cytotoxicity and heat release assays on the hybrid nanoparticles were performed here for the first time. The heat induction results indicate that these new magnetic hybrid nanoparticles are capable of increasing the temperature by more than 5 °C, the minimal temperature rise required for being effectively used in hyperthermia treatments. The biocompatibility assays conducted under different concentrations, in the presence and in the absence of an external alternating current magnetic field, did not reveal any cytotoxicity. Therefore, the overall results indicate that the investigated hybrid nanoparticles have a great potential to be used as carrier systems for cancer treatment by hyperthermia.

As(os) residentes parecem ter contribuído para a resiliência dos serviços de saúde na Atenção Básica durante a pandemia apesar das suas atividades não terem sido desenvolvidas integralmente, haja vista as limitações estruturais, financeiras, políticas e teórico-práticas.

ABSTRACT Family health residencies show advances for work, especially in Primary Care, which in the context of the COVID-19 pandemic remains as a gateway to the health network. The resilience of a health system refers to its ability to absorb, adapt, transform, and remain functional when subjected to a crisis. The objective was to analyze the role of health residents for the resilience of Primary Care in the context of COVID-19. The study, of a qualitative and quantitative nature, through a self-administered online questionnaire, included health residents who worked in Primary Care during the pandemic as subjects. The data observed the profile of the participants and aspects related to their resilience. The Epi Info program and thematic content analysis were used for data analysis. 289 residents participated, mostly women, cisgender, white. The analytical categories were identified: Contribution to the continuity of actions in Primary Care; Responsiveness to the needs of the pandemic; and Assistance and educational innovations. The residents seem to have contributed to the resilience of health services in Primary Care during the pandemic, despite their activities not being fully developed, given the structural, financial, political, and theoretical-practical limitations.

A function-based typology for Earth's ecosystems.

As the United Nations develops a post-2020 global biodiversity framework for the Convention on Biological Diversity, attention is focusing on how new goals and targets for ecosystem conservation might serve its vision of 'living in harmony with nature'1,2. Advancing dual imperatives to conserve biodiversity and sustain ecosystem services requires reliable and resilient generalizations and predictions about ecosystem responses to environmental change and management3. Ecosystems vary in their biota4, service provision5 and relative exposure to risks6, yet there is no globally consistent classification of ecosystems that reflects functional responses to change and management. This hampers progress on developing conservation targets and sustainability goals. Here we present the International Union for Conservation of Nature (IUCN) Global Ecosystem Typology, a conceptually robust, scalable, spatially explicit approach for generalizations and predictions about functions, biota, risks and management remedies across the entire biosphere. The outcome of a major cross-disciplinary collaboration, this novel framework places all of Earth's ecosystems into a unifying theoretical context to guide the transformation of ecosystem policy and management from global to local scales. This new information infrastructure will support knowledge transfer for ecosystem-specific management and restoration, globally standardized ecosystem risk assessments, natural capital accounting and progress on the post-2020 global biodiversity framework.

Enhanced mechanical properties, anti-biofilm activity, and cytocompatibility of a methacrylate-based polymer loaded with native multiwalled carbon nanotubes.

OBJECTIVES: We aimed to optimize the mechanical and biological properties of a conventional methacrylate-based dental polymer by loading it with double- and triple-walled carbon nanotubes as growth (DTWCNTG). METHODS: A formulation of bisphenol A-glycidyl methacrylate and triethylene glycol dimethacrylate (mass ratio = 2:1) was mixed with DTWCNTG at concentrations of 0.0% (control), 0.001%, 0.005%, and 0.010%. The concentrations were physicochemical and morphologically evaluated, and antibacterial activity was assessed by seeding a Streptococcus mutans strain (ATCC 25175) on the experimental polymeric surfaces. Cellular survival and osteodifferentiation were evaluated in epithelial (HaCat) and preosteoblast cells (MC3T3-E1). RESULTS: The 0.001% DTWCNTG concentration yielded higher compressive strength, elastic modulus, flexural strength, flexural modulus, water sorption, and solubility than the control. The degree of conversion and color did not significantly change with a low amount of DTWCNTG incorporated into the polymer. Antibacterial activity significantly improved when tested on the 0.001% DTWCNTG discs. No groups showed cytotoxicity in a short-term analysis and adding DTWCNTG favored MC3T3-E1 mineralization over the control, particularly in the 0.001% formulation. SIGNIFICANCE: The micro-addition of 0.001% DTWCNTG confers mechanical resistance, antimicrobial properties, and bioactivity to methacrylate-based polymers without significantly compromising color. Incorporating DTWCNTG improved dental composite properties and could be a biomodified material for minimally invasive procedures.

Equisetum hyemale-derived unprecedented bioactive composite for hard and soft tissues engineering.

Although Bioactive Glasses (BGs) have been progressively optimized, their preparation often still involves the use of toxic reagents and high calcination temperatures to remove organic solvents. In the present work, these synthesis related drawbacks were overcome by treating the ashes from the Equisetum hyemale plant in an ethanol/water solution to develop a bioactive composite [glass/carbon (BG-Carb)]. The BG-Carb was characterized by scanning electron microscopy, and transmission electron microscopy; and its chemical composition was assessed by inductively coupled plasma-optical emission spectroscopy. Brunauer-Emmett-Teller gas adsorption analysis showed a specific surface area of 121 m2 g-1. The formation of hydroxyapatite (HA) surface layer in vitro was confirmed by Fourier-transform infrared spectroscopy analysis before and after immersion in simulated body fluid (SBF) solution. The Rietveld refinement of the XRD patterns and selected area electron diffraction analyses confirmed HA in the sample even before immersing it in SBF solution. However, stronger evidences of the presence of HA were observed after immersion in SBF solution due to the surface mineralization. The BG-Carb samples showed no cytotoxicity on MC3T3-E1 cells and osteo-differentiation capacity similar to the positive control. Altogether, the BG-Carb material data reveals a promising plant waste-based candidate for hard and soft tissue engineering.

Scientific foundations for an ecosystem goal, milestones and indicators for the post-2020 global biodiversity framework.

Despite substantial conservation efforts, the loss of ecosystems continues globally, along with related declines in species and nature's contributions to people. An effective ecosystem goal, supported by clear milestones, targets and indicators, is urgently needed for the post-2020 global biodiversity framework and beyond to support biodiversity conservation, the UN Sustainable Development Goals and efforts to abate climate change. Here, we describe the scientific foundations for an ecosystem goal and milestones, founded on a theory of change, and review available indicators to measure progress. An ecosystem goal should include three core components: area, integrity and risk of collapse. Targets-the actions that are necessary for the goals to be met-should address the pathways to ecosystem loss and recovery, including safeguarding remnants of threatened ecosystems, restoring their area and integrity to reduce risk of collapse and retaining intact areas. Multiple indicators are needed to capture the different dimensions of ecosystem area, integrity and risk of collapse across all ecosystem types, and should be selected for their fitness for purpose and relevance to goal components. Science-based goals, supported by well-formulated action targets and fit-for-purpose indicators, will provide the best foundation for reversing biodiversity loss and sustaining human well-being.

MOF-derived Co/Cu-embedded N-doped carbon for trifunctional ORR/OER/HER catalysis in alkaline media.

In this report, we demonstrate a bimetallic Co/Cu-embedded N-doped carbon structure for trifunctional catalysis of oxygen reduction, oxygen evolution and hydrogen evolution reactions in alkaline media. A hybrid catalyst synthesized through a metal-organic framework-based process (M-NC-CoCu) enables an active trifunctional catalysis due to its multi-faceted favorable characteristics. It is believed that a range of catalytically active sites are formed through the approach including well-dispersed tiny CuCo2O4 phases, a high concentration of pyridinic and graphitic N, and Cu-Ox, Cu-Nx and Co-Nx moieties. In addition, a high-surface-area morphology with a high concentration of sp2 bonding, which is beneficial for facilitated electron conduction, further contributes to the performance as an electrocatalyst.

Guiding principles for rewilding.

There has been much recent interest in the concept of rewilding as a tool for nature conservation, but also confusion over the idea, which has limited its utility. We developed a unifying definition and 10 guiding principles for rewilding through a survey of 59 rewilding experts, a summary of key organizations' rewilding visions, and workshops involving over 100 participants from around the world. The guiding principles convey that rewilding exits on a continuum of scale, connectivity, and level of human influence and aims to restore ecosystem structure and functions to achieve a self-sustaining autonomous nature. These principles clarify the concept of rewilding and improve its effectiveness as a tool to achieve global conservation targets, including those of the UN Decade on Ecosystem Restoration and post-2020 Global Biodiversity Framework. Finally, we suggest differences in rewilding perspectives lie largely in the extent to which it is seen as achievable and in specific interventions. An understanding of the context of rewilding projects is the key to success, and careful site-specific interpretations will help achieve the aims of rewilding.

Recientemente ha habido mucho interés por el concepto de retorno a la vida silvestre como herramienta para la conservación de la naturaleza, pero también ha habido confusión por la idea que ha limitado su utilidad. Desarrollamos una definición unificadora y diez principios básicos para el retorno a la vida silvestre por medio de encuestas a 59 expertos en retorno a la vida silvestre, un resumen de las visiones de las organizaciones más importantes para el retorno a la vida silvestre y talleres que involucraron a más de 100 participantes de todo el mundo. Los principios básicos transmiten que el retorno a la vida silvestre existe en un continuo de escala, conectividad y nivel de influencia humana y que su objetivo es restaurar la estructura y las funciones del ecosistema para lograr una naturaleza autónoma autosustentable. Estos principios aclaran el concepto del retorno a la vida silvestre e incrementan su efectividad como herramienta para lograr los objetivos mundiales de conservación, incluyendo aquellos de la Década de la ONU para la Restauración de Ecosistemas y el Marco de Trabajo de la Biodiversidad Global post 2020. Finalmente, sugerimos que las diferencias en las perspectivas del retorno a la vida silvestre yacen principalmente en el grado al que es visto como factible y en intervenciones específicas. Un entendimiento del contexto de los proyectos de retorno a la vida silvestre es importante para el éxito, y las interpretaciones específicas de sitio ayudarán a lograr las metas del retorno a la vida silvestre. Principios Básicos para el Retorno a la Vida Silvestre.

Preparation of glass-ionomer cement containing ethanolic Brazilian pepper extract (Schinus terebinthifolius Raddi) fruits: chemical and biological assays.

Plants may contain beneficial or potentially dangerous substances to humans. This study aimed to prepare and evaluate a new drug delivery system based on a glass-ionomer-Brazilian pepper extract composite, to check for its activity against pathogenic microorganisms of the oral cavity, along with its in vitro biocompatibility. The ethanolic Brazilian pepper extract (BPE), the glass-ionomer cement (GIC) and the composite GIC-BPE were characterized by scanning electron microscopy, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), and thermal analysis. The BPE compounds were identified by UPLC-QTOF-MS/MS. The release profile of flavonoids and the mechanical properties of the GIC-BPE composite were assessed. The flavonoids were released through a linear mechanism governing the diffusion for the first 48 h, as evidenced by the Mt/M∞ relatively to [Formula: see text], at a diffusion coefficient of 1.406 × 10-6 cm2 s-1. The ATR-FTIR analysis indicated that a chemical bond between the GIC and BPE components may have occurred, but the compressive strength of GIC-BPE does not differ significantly from that of this glass-ionomer. The GIC-BPE sample revealed an ample bacterial activity at non-cytotoxic concentrations for the human fibroblast MRC-5 cells. These results suggest that the prepared composite may represent an alternative agent for endodontic treatment.

Assessment instruments for lower urinary tract dysfunction in children: Symptoms, characteristics and psychometric properties.

INTRODUCTION: The use of instruments to assess symptoms of the lower urinary tract has increased mainly when it comes to pediatric urology. The search for a validated and reliable one for use in clinical practice should be a concern of the professionals involved in the care of these children. OBJECTIVE: The aim of this study was to analyze the assessment instruments for lower urinary tract dysfunction in children regarding: symptoms, characteristics and psychometric properties. STUDY DESIGN: PubMed and Latin American and Caribbean Literature in Health Sciences databases were searched. The PICO strategy was used to construct the research question and bibliographic search. Keywords included voiding disorders, LUTS, Child, Surveys and Questionnaires. RESULTS: Nine articles were identified. The construct observed by all instruments was bladder dysfunction and seven instruments also assessed bowel dysfunction. Thirty different events were addressed. In eight instruments the respondents are the parents. The age of the target population ranged from three to eighteen years and regarding the number of items, an average of 21.8 items was observed. Six instruments showed good results of reliability and four presented good results of accuracy. CONCLUSIONS: The instruments included a wide range of symptoms related to dysfunction. Only two reported all validation and reliability tests, however six instruments showed good reliability results, making them eligible for the cross-cultural adaptation and validation process for use in countries other than those of the instrument's origin.

Prevalence of induced abortion and associated factors in a cohort of women living with HIV/AIDS, Rio de Janeiro, Brazil, 1996-2016. / Prevalência e fatores associados ao aborto induzido no ingresso em uma coorte de mulheres vivendo com HIV/aids, Rio de Janeiro, Brasil, 1996-2016.

The aim of this study was to verify the prevalence of induced abortion and associated factors at the time of inclusion in a cohort of women living with HIV/AIDS in the city of Rio de Janeiro, Brazil, from 1996 to 2016. Eligibility criteria for inclusion in the cohort were female sex at birth, age 18 years and older, and confirmed HIV infection. At the baseline visit, data on sexual, reproductive, and behavioral aspects and HIV infection were obtained through a face-to-face interview with the attending physician. Lifetime prevalence of induced abortion was calculated, and factors associated with induced abortion were verified by multiple logistic regression for all the women and for those with previous pregnancy. In the entire cohort of women, 30.4% reported a history of induced abortion, compared to 33.5% in women with previous pregnancy. Frequency of reported induced abortion showed a significant reduction during the period (41.7% in 1996-2000 versus 22.5% in 2011-2016, p < 0.001). Factors associated with induced abortion, both for the entire cohort and for the women with previous pregnancy, were age, schooling, ≥ 5 lifetime sexual partners, teenage pregnancy, lifetime use of any illicit drug, and inclusion in the cohort after the year 2005. Changes in the socioeconomic, sexual, reproductive, and HIV infection profile are possible explanations for the reduction in abortions during the period. Studies that use direct methods to measure abortion should be conducted in other populations to confirm the downward trend in induced abortion and its determinants in Brazil.

O objetivo deste estudo é verificar a prevalência e os fatores associados ao aborto induzido no ingresso em uma coorte de mulheres vivendo com HIV/aids, no Município do Rio de Janeiro, Brasil, no período 1996-2016. O critério de elegibilidade para o ingresso na coorte era ser do sexo feminino ao nascimento, ter mais de 18 anos de idade e ter infecção comprovada pelo HIV. Na visita inicial, dados sobre aspectos sexuais, reprodutivos, comportamentais e da infecção pelo HIV foram obtidos durante entrevista face a face com o médico assistente. Foi calculada a prevalência de aborto induzido na vida e verificados os fatores associados ao aborto induzido por meio de regressão logística múltipla, para o total de mulheres e entre aquelas com gestação prévia. Do total de mulheres, 30,4% referiram algum aborto induzido na vida, sendo este valor de 33,5% em mulheres com gestação prévia. A frequência de aborto induzido relatado apresentou queda significativa no período analisado (41,7% de 1996-2000 vs. 22,5% de 2011-2016, p < 0,001). Os fatores associados ao aborto induzido, tanto para o total de mulheres quanto para aquelas com gestação prévia, foram o aumento da idade, escolaridade mais elevada, número de parceiros sexuais na vida ≥ 5, gestação na adolescência, uso de qualquer droga ilícita na vida e período de ingresso na coorte após 2005. Mudanças no perfil socioeconômico, sexual, reprodutivo e da infecção pelo HIV são explicações possíveis para a redução da prática do aborto no período. Estudos que utilizem métodos de aferição direta do aborto devem ser conduzidos em outras populações, para confirmar a tendência de queda do aborto induzido no país e seus determinantes.

El objetivo de este estudio es verificar la prevalencia y los factores asociados al aborto inducido en el ingreso en una cohorte de mujeres, que viven con VIH/sida, en el municipio de Rio de Janeiro, durante el período 1996-2016. El criterio de elegibilidad para el ingreso en la cohorte era ser del sexo femenino al nacer, tener más de 18 años de edad y sufrir una infección comprobada por VIH. En la visita inicial, datos sobre aspectos sexuales, reproductivos, comportamentales y de infección por el VIH se obtuvieron durante la entrevista cara a cara con el médico asistente. Se calculó la prevalencia del aborto inducido en la vida y se verificaron los factores asociados al aborto inducido mediante regresión logística múltiple, para el total de mujeres y entre aquellas con gestación previa. Del total de mujeres, un 30,4% refería algún aborto inducido en la vida, siendo ese valor de un 33,5% en mujeres con gestación previa. La frecuencia de aborto inducido relatado presentó una caída significativa durante el período analizado (un 41,7% en el período 1996-2000 vs. 22,5% en el período 2011-2016, p < 0,001). Los factores asociados al aborto inducido, tanto para el total de mujeres, como para aquellas con gestación previa, fueron el aumento de la edad de la mujer, escolaridad más elevada, número de parejas sexuales en la vida ≥ 5, gestación en la adolescencia, consumo de cualquier droga ilícita en la vida y período de ingreso en la cohorte tras 2005. Cambios en el perfil socioeconómico, sexual, reproductivo y de infección por VIH son explicaciones posibles para la reducción de la realización de abortos durante el período. Se deben llevar a cabo estudios que utilicen métodos de medición directa del aborto en otras poblaciones para confirmar la tendencia de caída del aborto inducido en el país y sus determinantes.
