RESUMO

Objetivo: estimar a prevalência de nascimento prematuro em gestantes infectadas pela Covid-19, comparar índices de prematuridade entre infectadas e não infectadas e elucidar fatores associados à prematuridade. Métodos: coorte retrospectiva, com coleta de dados por inquérito online, de abril a dezembro de 2022, com mulheres que estiveram gestantes durante a pandemia, com acesso à internet, idade superior a 18 anos e que preencheram o primeiro inquérito online. Protocolo de pesquisa aprovado pelo Comitê de Ética. Resultados: primeiro inquérito respondido por 304 gestantes/puérperas, e o segundo por 82 (27%), compondo a amostra final. O índice de prematuridade no primeiro inquérito foi de 7,2% (n=14), já no segundo, 8,5% (n=7). A infecção pela Covid-19 não foi associada à prematuridade. A prematuridade associou-se a baixo peso, à necessidade de internação em centros de terapia intensiva neonatal e internações após o nascimento. Conclusão: a infecção pela Covid-19 não influenciou no aumento de nascimentos prematuros.


Objective: to estimate the prevalence of preterm birth in pregnant women infected with Covid-19, compare prematurity rates between infected and non-infected, and elucidate factors associated with prematurity. Methods: a retrospective cohort study was conducted using online survey data collected from April to December 2022, involving women who were pregnant during the pandemic, had internet access, were over 18 years old, and completed the initial online survey. The research protocol was approved by the Ethics Committee. Results: the initial survey was completed by 304 pregnant/postpartum women, and the follow-up survey by 82 (27%), comprising the final sample. The preterm birth rate in the initial survey was 7.2% (n=14), and in the follow-up survey, it was 8.5% (n=7). Covid-19 infection was not associated with prematurity. Prematurity was associated with low birth weight, the need for neonatal intensive care unit admission, and postnatal hospitalizations. Conclusion: Covid-19 infection did not influence an increase in preterm births.


Objetivo: estimar la prevalencia de partos prematuros en gestantes infectadas por Covid-19, comparar las tasas de prematuridad entre gestantes infectadas y no infectadas y determinar los factores asociados a la prematuridad. Métodos: estudio de cohorte retrospectivo, con recolección de datos mediante encuesta online, de abril a diciembre de 2022, con mujeres que estuvieron embarazadas durante la pandemia, con acceso a internet, mayores de 18 años y que completaron la primera encuesta online. El protocolo de investigación fue aprobado por el Comité de Ética. Resultados: la primera encuesta fue respondida por 304 gestantes/puérperas, y la segunda por 82 (27%), que conformaron la muestra final. La tasa de prematuridad en la primera encuesta fue del 7,2% (n=14), en la segunda, del 8,5% (n=7). La infección por Covid-19 no se asoció con la prematuridad. La prematuridad se asoció con bajo peso, necesidad de internación en centros de cuidados intensivos neonatales e internaciones después del nacimiento. Conclusión: La infección por Covid-19 no influyó en el aumento de nacimientos prematuros.

RESUMO

Despite increasing knowledge about small extracellular vesicle (sEV) composition and functions in cell-cell communication, the mechanism behind their biogenesis remains unclear. Here, we reveal for the first time that sEV biogenesis and release into the microenvironment are tightly connected with another important organelle, Lipid Droplets (LDs). The correlation was observed in several human cancer cell lines as well as patient-derived colorectal cancer stem cells (CR-CSCs). Our results demonstrated that external stimuli such as radiation, pH, hypoxia or lipid-interfering drugs, known to affect the number of LDs/cell, similarly influenced sEV secretion. Importantly, through multiple omics data, at both mRNA and protein levels, we revealed RAB5C as a potential important molecular player behind this organelle connection. Altogether, the potential to fine-tune sEV biogenesis by targeting LDs could significantly impact the amount, cargos and properties of these sEVs, opening new clinical perspectives.

RESUMO

INTRODUCTION: When mental disorders go undetected until later stages, they can result in poorer health outcomes for patients. Primary healthcare (PHC) stands as a strategic setting for the early identification and management of these mental disorders, given its role as the primary care environment for health service users. This scoping review has the objective of mapping and assessing screening instruments validated for mental disorders that are applicable in PHC, particularly regarding their measurement properties. METHODS AND ANALYSIS: This scoping review will include studies that have developed and validated screening instruments for mental disorders in the PHC context, irrespective of the age group. Searches will be conducted in MEDLINE, EMBASE, LILACS, CINAHL and PsycInfo without imposing restrictions on publication status, publication year or language. Additionally, we will scrutinise the references cited in the selected studies. Our inclusion criteria encompass studies examining any measurement property recommended by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) taxonomy. The selection process, data extraction and quality assessment of studies will be performed independently by pairs of reviewers. To evaluate the risk of bias within the selected studies, we will employ the COSMIN Risk of Bias 2 tools. The collected data will undergo analysis using descriptive statistics and will be presented in an evidence gap map format for each specific mental disorder. ETHICS AND DISSEMINATION: The findings from this review will be discussed through deliberative dialogue with stakeholders and disseminated through peer-reviewed publications and conference presentations. The project was approved by the Ethics Committee for Research at the University of Sorocaba (number: 66993323.9.0000.5500). TRIAL REGISTRATION NUMBER: Open Science Framework - 10.17605/OSF.IO/Z6T5M.

RESUMO

Neonatal stress affects psychological and physiological development and may be associated with affective disorders. The aim was to examine the effects of double neonatal stress (DNS) - a combination of limited bedding and nesting (LBN) and repeated maternal separation (MS) - on the oestrous cycle and sexual behaviour of adult female rats. LBN was achieved by removing part of the wood shavings from the boxes. In the control group, each box was lined with 100 g of wood shavings, while in the experimental group there were only 10 g of wood shavings. MS was performed from P1 (P0 = day of birth) to P15. At P90, the sexual response of females in oestrus was evaluated. Statistical analysis was performed using two-way analysis of variance followed by Tukey's test. The size and profile of the oestrous cycle and the sexual behaviour of female rats submitted to the DNS were considered, as well as the influence of female behaviour on the sexual response of male rats. Female rats submitted to DNS showed a reduction in the lordosis quotient, suggesting a reduction in female receptivity. These rats also showed a reduction in the number of hops and darts, the number of ear wiggles, and the genital exploration time rate, suggesting a reduction in proceptivity. The males that interacted with the females of the DNS group showed a reduction in intromission ratio. Experimental model that mimics neonatal factors that affect adult female sexual response will allow more effective interventions to prevent and treat such changes. In addition, analysis of the female sexual response makes it possible to assess the general state of health and quality of life. In female rats, DNS exerted inhibitory effects on sexual behaviour. LBN was probably the most important factor. In conclusion, combating childhood poverty can be a key measure to prevent problems in the sex life of adults and improve overall health.

RESUMO

Many expectant mothers use CBD to alleviate symptoms like nausea, insomnia, anxiety, and pain, despite limited research on its long-term effects. However, CBD passes through the placenta, affecting fetal development and impacting offspring behavior. We investigated how prenatal CBD exposure affects the insular cortex (IC), a brain region involved in emotional processing and linked to psychiatric disorders. The IC is divided into two territories: the anterior IC (aIC), processing socioemotional signals, and the posterior IC (pIC), specializing in interoception and pain perception. Pyramidal neurons in the aIC and pIC exhibit sex-specific electrophysiological properties, including variations in excitability and the excitatory/inhibitory balance. We investigated IC's cellular properties and synaptic strength in the offspring of both sexes from mice exposed to low-dose CBD during gestation (E5-E18; 3 mg/kg, s.c.). Prenatal CBD exposure induced sex-specific and territory-specific changes in the active and passive membrane properties, as well as intrinsic excitability and the excitatory/inhibitory balance, in the IC of adult offspring. The data indicate that in utero CBD exposure disrupts IC neuronal development, leading to a loss of functional distinction between IC territories. These findings may have significant implications for understanding the effects of CBD on emotional behaviors in offspring.

RESUMO

BACKGROUND: Several ablation confirmation software methods for minimum ablative margin assessment have recently been developed to improve local outcomes for patients undergoing thermal ablation of colorectal liver metastases. Previous assessments were limited to single institutions mostly at the place of development. The aim of this study was to validate the previously identified 5 mm minimum ablative margin (A0) using autosegmentation and biomechanical deformable image registration in a multi-institutional setting. METHODS: This was a multicentre, retrospective study including patients with colorectal liver metastases undergoing CT- or ultrasound-guided microwave or radiofrequency ablation during 2009-2022, reporting 3-year local disease progression (residual unablated tumour or local tumour progression) rates by minimum ablative margin across all institutions and identifying an intraprocedural contrast-enhanced CT-based minimum ablative margin associated with a 3-year local disease progression rate of less than 1%. RESULTS: A total of 400 ablated colorectal liver metastases (median diameter of 1.5 cm) in 243 patients (145 men; median age of 62 [interquartile range 54-70] years) were evaluated, with a median follow-up of 26 (interquartile range 17-40) months. A total of 119 (48.9%) patients with 186 (46.5%) colorectal liver metastases were from international institutions B, C, and D that were not involved in the software development. Three-year local disease progression rates for 0 mm, >0 and <5 mm, and 5 mm or larger minimum ablative margins were 79%, 15%, and 0% respectively for institution A (where the software was developed) and 34%, 19%, and 2% respectively for institutions B, C, and D combined. Local disease progression risk decreased to less than 1% with an intraprocedurally confirmed minimum ablative margin greater than 4.6 mm. CONCLUSION: A minimum ablative margin of 5 mm or larger demonstrates optimal local oncological outcomes. It is proposed that an intraprocedural minimum ablative margin of 5 mm or larger, confirmed using biomechanical deformable image registration, serves as the A0 for colorectal liver metastasis thermal ablation.

RESUMO

OBJECTIVE: To map evidence on nursing care for women with HELLP syndrome. METHOD: A scoping review with searches carried out in May 2023, independently, in the PubMed/MEDLINE, LILACS, Scopus, EMBASE, Web of Science, CINAHL, CAPES Theses and Dissertations Catalog and Cochrane Library databases, correlating the descriptors HELLP Syndrome, Nursing Care and Obstetric Nursing and its synonyms, without delimitation of time and language. Selection was carried out by three researchers independently and resolved by consensus. RESULTS: Of the 129 studies, ten were selected, which made up the final sample. The studies date from 2004 to 2022, with a predominance of English language and clinical case studies. A greater occurrence of the syndrome was observed in second-time pregnant women in the second decade of life, with a gestational age from 32 weeks, which resulted in an emergency cesarean section, and all newborns were discharged accompanied by their mothers. Studies that described nursing diagnoses and focused on nursing care were retrieved. From the review, 39 nursing care were identified. CONCLUSION: This review pointed out the magnitude of the syndrome, however with a lack of studies.

RESUMO

OBJECTIVE: To evaluate efficacy, safety, and adherence to using adjustable compression wraps (ACWs) for upper limb volume control in women with breast cancer-related lymphedema. DESIGN AND SETTING: Randomized controlled trial at a reference hospital for breast cancer treatment in Brazil. PARTICIPANTS: Women in control phase of the breast cancer-related lymphedema. INTERVENTIONS: Compared use of ACWs versus compressive mesh. MAIN MEASURES: Evaluated before treatment, at 30 days, and 6 months after initiating therapy. The primary outcome was the change in excess limb volume. Secondary outcomes included adherence, incidence of adverse events, functionality, quality of life, and hand grip. Statistical analysis involved calculating the effect size (ES) with a 95% confidence interval. RESULTS: Were included 71 women with mean excess limb volume of 321.79 mL (±194.98). In the 30-day analysis (Time 1), a reduction of 37.6 mL in volume was observed only in the ACW group (p = .041, ES 0.20), with improved functionality (p = .013, ES 0.22). In the six months analysis (Time 2), the compressive mesh group increased by 2.48% in volume (p = .023, ES 0.26) and demonstrated improvement functionality (p = .036, ES 0.27). Mild adverse events and satisfactory adherence were observed. However, in the intergroup comparison, no statistically significant difference was observed for any evaluated outcome-excess volume, incidence of adverse events, adherence, hand grip, quality of life, and functionality between the groups (p > .05) at both times. CONCLUSIONS: Both compression therapies achieved satisfactory adherence, were safe, effective and equivalent for controlling limb volume in breast cancer-related lymphedema.

RESUMO

This paper involves the analysis of the quality of anthropometric data on children under five years of age in two information systems in the State of São Paulo. The sample included 2,117,108 children from the Food and Nutrition Surveillance System (SISVAN), and 748,551 from the State Milk Project (VIVALEITE). Initially, we evaluated the frequency of missing values and others outside the equipment spectrum and calculated the digit-to-weight preference index. After calculating height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ), we flagged the biologically implausible values (BIV) and calculated the standard deviation (SD). For each municipality, we calculated the mean and the SD of HAZ, WAZ, and BAZ; and plotted the SD values as a function of the mean. The digit-to-weight preference index was greater among children aged between 24 and 59 months in SISVAN. The frequency of BIV for HAZ (SISVAN 2.56%; VIVALEITE 0.98%) was higher than for WAZ (SISVAN 2.10%; VIVALEITE 0.18%). For HAZ, variations among municipalities were more pronounced in VIVALEITE than in SISVAN. The height variable presents low reliability in both systems. The weight variable reveals satisfactory quality in VIVALEITE and unsatisfactory quality in SISVAN.


O objetivo foi analisar a qualidade dos dados antropométricos de crianças menores de cinco anos em dois sistemas de informação no estado de São Paulo. A amostra compreendeu 2.117.108 crianças do Sistema de Vigilância Alimentar e Nutricional (Sisvan) e 748.551 do Projeto Estadual do Leite (Vivaleite). Inicialmente, avaliamos a frequência de valores faltantes e fora do espectro do equipamento, e calculamos o índice de preferência de dígito para peso. Após calcular os índices de altura para idade (A-I), peso para idade (P-I) e índice de massa corporal para idade (IMC-I), identificamos os valores biologicamente implausíveis (VBI) e calculamos o desvio-padrão (DP). Para cada município, calculamos a média e o DP de A-I, P-I e IMC-I; e plotamos os valores de DP em função da média. A preferência de dígito no peso foi maior em crianças de 24 a 59 meses no Sisvan. A frequência de VBI para A-I (SISVAN 2,56%; Vivaleite 0,98%) foi maior do que para P-I (Sisvan 2,10%; Vivaleite 0,18%). Para o índice A-I as variações entre os municípios foram mais acentuadas no Vivaleite do que no Sisvan. A variável altura apresentou baixa confiabilidade nos dois sistemas. A variável peso apresentou qualidade satisfatória no Vivaleite e insatisfatória no Sisvan.

RESUMO

BACKGROUND: Viral respiratory infections may precipitate type 1 diabetes (T1D). A possible association between the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19, and the incidence of T1D is being determined. This study was carried out using Portuguese registries, aiming at examining temporal trends between COVID-19 and T1D. METHODS: Hospital data, comparing the incidence before and during the COVID-19 pandemic, from children and young adults diagnosed with new-onset T1D, was acquired beginning in 2017 and until the end of 2022. Data was obtained from nine different Portuguese hospital units. The impact of the COVID-19 pandemic, beginning in March 2020, was assessed comparing the annual numbers of new-onset T1D cases. The annual median levels of glucose, glycated hemoglobin (HbA1c) and fasting C-peptide at T1D diagnosis were compared. The annual number of diabetic ketoacidosis (DKA) episodes among new T1D cases was also assessed at two centers. RESULTS: In total, data from 574 newly diagnosed T1D patients was analyzed, including 530 (92.3%) children. The mean ages for child and adult patients were 9.1 (SD 4.4) and 32.8 (SD 13.6) years, respectively. 57.8% (331/573) were male, one patient had unknown sex. The overall median (25-75 percentiles) levels of glucose, HbA1c and fasting C-peptide at diagnosis were 454 mg/dL (356-568), 11.8% (10.1-13.4) and 0.50 µg/L (0.30-0.79), respectively. DKA at T1D diagnosis was present in 48.4% (76/157). For eight centers with complete 2018 to 2021 data (all calendar months), no overall significant increase in T1D cases was observed during the COVID-19 pandemic, i.e. 90 cases in 2018, 90 cases in 2019, 112 in 2020 and 100 in 2021 (P for trend = 0.36). Two of the centers, Faro (CHUA) and Dona Estefânia (CHULC) hospitals, did however see an increase in T1D from 2019 to 2020. No significant changes in glucose (P = 0.32), HbA1c (P = 0.68), fasting C-peptide (P = 0.20) or DKA frequency (P = 0.68) at the time of T1D diagnosis were observed over the entire study period. CONCLUSION: The T1D incidence did not increase significantly, when comparing the years before and during the COVID-19 pandemic, nor did key metabolic parameters or number of DKA episodes change.

RESUMO

Many expectant mothers use CBD to alleviate symptoms like nausea, insomnia, anxiety, and pain, despite limited research on its long-term effects. However, CBD passes through the placenta, affecting fetal development and impacting offspring behavior. We investigated how prenatal CBD exposure affects the insular cortex (IC), a brain region involved in emotional processing and linked to psychiatric disorders. The IC is divided into two territories: the anterior IC (aIC), processing socioemotional signals, and the posterior IC (pIC), specializing in interoception and pain perception. Pyramidal neurons in the aIC and pIC exhibit sex-specific electrophysiological properties, including variations in excitability and the excitatory/inhibitory balance. We investigated IC's cellular properties and synaptic strength in the offspring of both sexes from mice exposed to low-dose CBD during gestation (E5-E18; 3mg/kg, s.c.). Prenatal CBD exposure induced sex-specific and territory-specific changes in the active and passive membrane properties, as well as intrinsic excitability and the excitatory/inhibitory balance, in the IC of adult offspring. The data indicate that in-utero CBD exposure disrupts IC neuronal development, leading to a loss of functional distinction between IC territories. These findings may have significant implications for understanding the effects of CBD on emotional behaviors in offspring.

RESUMO

INTRODUCTION: Asthma symptoms are dyspnea, chronic cough, wheezing, chest tightness, or chest discomfort, which can directly limit the activities of daily living (ADL), which is frequently reported by adults with asthma. Evaluating ADL with a reliable protocol at the usual speed is necessary. OBJECTIVES: To investigate the validity, reliability, minimal detectable change (MDC), and standard error of measurement (SEM) of the Londrina ADL Protocol (LAP) for adults with asthma. METHODS: Adults with asthma were evaluated with the LAP test. Spearman's correlation coefficient was used to verify validity with the 6-min walk test (6MWT), Glittre-ADL test, and London Chest Activity of Daily Living (LCADL). To test the reliability, the test was reapplied in at least 30 min; the Wilcoxon test and Intraclass Correlation Coefficient (ICC), SEM, MDC, and learning effect were performed. RESULTS: Fifty-three individuals were included (26% men, 43 ± 15 years, BMI 28 ± 8 kg/m2, FEV1 70 ± 24%predicted). For convergent validity, the LAP test was correlated with the 6MWT, Glittre-ADL, and LCADL scale (r = -0.49, 0.71, and 0.30, respectively; p < 0.03). There was a difference in test-retest (p < 0.0001) and reliability analysis shows ICC3 of 0.94, SEM of 14.88 s (22%), and MDC of 41.23 s (15%). Furthermore, the individuals performed the second test with -23 ± 19 (7.9%) s. CONCLUSION: The LAP test is valid and reliable for assessing limitations during ADL in adults with asthma. Considerable learning effect was observed, therefore, the best of two measures may avoid underestimation.

RESUMO

Amphibians represent a diverse group of tetrapods, marked by deep divergence times between their three systematic orders and families. Studying amphibian biology through the genomics lens increases our understanding of the features of this animal class and that of other terrestrial vertebrates. The need for amphibian genomics resources is more urgent than ever due to the increasing threats to this group. Amphibians are one of the most imperiled taxonomic groups, with approximately 41% of species threatened with extinction due to habitat loss, changes in land use patterns, disease, climate change, and their synergistic effects. Amphibian genomics resources have provided a better understanding of ontogenetic diversity, tissue regeneration, diverse life history and reproductive modes, antipredator strategies, and resilience and adaptive responses. They also serve as critical models for understanding widespread genomic characteristics, including evolutionary genome expansions and contractions given they have the largest range in genome sizes of any animal taxon and multiple mechanisms of genetic sex determination. Despite these features, genome sequencing of amphibians has significantly lagged behind that of other vertebrates, primarily due to the challenges of assembling their large, repeat-rich genomes and the relative lack of societal support. The advent of long-read sequencing technologies, along with computational techniques that enhance scaffolding capabilities and streamline computational workload is now enabling the ability to overcome some of these challenges. To promote and accelerate the production and use of amphibian genomics research through international coordination and collaboration, we launched the Amphibian Genomics Consortium (AGC) in early 2023. This burgeoning community already has more than 282 members from 41 countries (6 in Africa, 131 in the Americas, 27 in Asia, 29 in Australasia, and 89 in Europe). The AGC aims to leverage the diverse capabilities of its members to advance genomic resources for amphibians and bridge the implementation gap between biologists, bioinformaticians, and conservation practitioners. Here we evaluate the state of the field of amphibian genomics, highlight previous studies, present challenges to overcome, and outline how the AGC can enable amphibian genomics research to "leap" to the next level.

RESUMO

The safety of exercise practice by individuals with cardiovascular disease is due to a good clinical evaluation to identify patients with a higher risk of adverse events, thus the study of simple variables capable of predicting the rate of events during exercise is relevant and may provide better screening tools to be applied in the clinical practice. The study aimed to evaluate if clinical and physical parameters can predict the rate of adverse events during exercise-based cardiac rehabilitation. This was a cohort study that followed 73 patients during 24 sessions of exercise. Were registered 217 simple adverse events, at a rate of 2.5 events per hour of exercise. We found that higher adiposity, worse pulmonary function, lower functional capacity, and reduced heart rate variability were significant and acceptable predictors of adverse events during exercise, according to the ROC curve analysis. We state that these simple physical parameters may be useful for cardiac risk stratification in cardiac rehabilitation programs with low resources, contributing to its safety.

RESUMO

S. scabra is an important forage and extremophilic plant native to the Brazilian Caatinga semiarid region. It has only recently been subjected to omics-based investigations, and the generated datasets offer insights into biotechnologically significant candidates yet to be thoroughly examined. INSs (inositol and its derivatives) and RFO (raffinose oligosaccharide family) pathways emerge as pivotal candidates, given their critical roles in plant physiology. The mentioned compounds have also been linked to negative impacts on the absorption of nutrients in mammals, affecting overall nutritional intake and metabolism. Therefore, studying these metabolic pathways is important not just for plants but also for animals who depend on them as part of their diet. INS and RFO pathways in S. scabra stood out for their abundance of identified loci and enzymes. The enzymes exhibited genomic redundancy, being encoded by multiple loci and various gene families. The phylogenomic analysis unveiled an expansion of the PIP5K and GolS gene families relative to the immediate S. scabra ancestor. These enzymes are crucial for synthesizing key secondary messengers and the RFO precursor, respectively. Transcriptional control of the studied pathways was associated with DOF-type, C2H2, and BCP1 transcription factors. Identification of biological processes related to INS and RFO metabolic routes in S. scabra highlighted their significance in responding to stressful conditions prevalent in the Caatinga environment. Finally, RNA-Seq and qPCR data revealed the relevant influence of genes of the INS and RFO pathways in the S. scabra response to water deprivation. Our study deciphers the genetics and transcriptomics of the INS and RFO in S. scabra, shedding light on their importance for a Caatinga-native plant and paving the way for future biotechnological applications in this species and beyond.

RESUMO

Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed, two of which focus on processes contributing to genetic diversity conservation: maintaining genetically distinct populations and ensuring populations are large enough to maintain genetic diversity. The major advantage of these indicators is that they can be estimated with or without DNA-based data. However, demonstrating their feasibility requires addressing the methodological challenges of using data gathered from diverse sources, across diverse taxonomic groups, and for countries of varying socio-economic status and biodiversity levels. Here, we assess the genetic indicators for 919 taxa, representing 5271 populations across nine countries, including megadiverse countries and developing economies. Eighty-three percent of the taxa assessed had data available to calculate at least one indicator. Our results show that although the majority of species maintain most populations, 58% of species have populations too small to maintain genetic diversity. Moreover, genetic indicator values suggest that IUCN Red List status and other initiatives fail to assess genetic status, highlighting the critical importance of genetic indicators.

RESUMO

Contexto - A alimentação inadequada nos primeiros anos de vida está associada à morbimortalidade de crianças, representada por doenças infecciosas, afecções respiratórias, cárie dental, desnutrição, excesso de peso e carências específicas de micronutrientes como de ferro, zinco e vitamina A. O Estudo Nacional de Alimentação e Nutrição Infantil (ENANI), realizado em 2019 com crianças brasileiras de até 5 anos, mostrou uma redução na prevalência de anemia de 20,9%, em 2006, para 10,1%, em 2019, com diferenças entre as regiões brasileiras. Evidências indicam que o fornecimento de alimentos complementares fortificados a crianças dos 6 aos 23 meses podem reduzir a anemia em 43% e aumentar as concentrações de hemoglobina de forma significativa. Pergunta - Qual é a efetividade das estratégias de fortificação de micronutrientes em pó (MNP) implementadas na alimentação de crianças de 6 meses até 59 meses? Métodos - As buscas por revisões sistemáticas (RS) foram realizadas em abril de 2024 nas bases de dados Lilacs - Literatura Latino-Americana e do Caribe em Ciências da Saúde, Pubmed, Embase e Epistemonikos. Nesta revisão rápida, apenas a seleção de estudos foi realizada em duplicidade e de modo independente. Resultados - As buscas resultaram em 109 registros recuperados. Após seleção por leitura de títulos e resumos, 17 RS elegíveis foram lidas na íntegra, das quais quatro foram incluídas. Os achados foram organizados de acordo com grupos de desfechos avaliados nos estudos: anemia e seus indicadores, estado nutricional, níveis séricos de micronutrientes, eventos adversos.
