Federal transfers to municipalities through parliamentary amendments: implications for SUS funding. / Transferências federais por emendas parlamentares aos municípios: implicações para o financiamento do SUS.

The present article analyzes the transfers from parliamentary amendments by the Ministry of Health to municipalities to finance public health actions and services from 2015 to 2021. A descriptive and exploratory study was carried out with secondary data, including all Brazilian cities. Resources from amendments showed an increase, particularly from 2018 onwards, indicating the expansion of their relevance for financing SUS. From 2016 to 2021, over 80% was allocated to municipalities, representing 9.5% of all federal transfers, with 91.2% for operational expenses. Transfers from amendments differ from regular transfers due to greater instability and per capita variation among the amounts collected by municipalities and due to the fact that they allocate most resources to the Northeast and primary care to the detriment of the Southeast and medium and high complexity care. These transfers represent a differentiated modality of resource allocation in SUS that produces new distortions and asymmetries, with implications for intergovernmental relations, as well as between the executive and legislative powers, increasing the risk of the discontinuity of actions and services and imposing challenges for the municipal management.

O artigo tem como objetivo analisar as transferências por emendas parlamentares do Ministério da Saúde aos municípios para o financiamento de ações e serviços públicos de saúde, de 2015 a 2021. Foi realizado estudo descritivo e exploratório com dados secundários, abrangendo a totalidade de municípios brasileiros. Os recursos provenientes de emendas apresentaram aumento, em especial a partir de 2018, indicando a expansão de sua relevância para o financiamento do SUS. No período de 2016 a 2021, mais de 80% foram alocados aos municípios, representando 9,5% dos repasses federais, com 91,2% de natureza de custeio. As transferências por emendas diferem dos repasses regulares por possuir maior instabilidade e variação per capita entre os montantes captados pelos municípios, e por destinar a maior parte dos recursos ao Nordeste e à atenção primária, em detrimento do Sudeste e da média e alta complexidade. Configura-se uma modalidade diferenciada de alocação de recursos no SUS que produz novas distorções e assimetrias, com implicações para as relações intergovernamentais e entre os poderes executivo e legislativo, ampliando o risco de descontinuidade de ações e serviços e impondo desafios para as gestões municipais.

Diagnostic accuracy of interleukin-6, interleukin-10 and tumor necrosis factor alpha cytokine levels in patients with mild cognitive impairment: systematic review and meta-analysis.

There is growing evidence suggesting an association between neurodegeneration and inflammation playing a role in the pathogenesis of age-associated diseases, including Alzheimer's disease (AD) and Mild Cognitive Impairment (MCI). Objective: A systematic review and meta-analysis were performed to verify evidence on the diagnostic accuracy parameters of the inflammatory cytokines interleukin-6 (IL-6), interleukin-10 (IL-10) and tumor necrosis factor alpha (TNF-α). Methods: A search of Medical Literature Analysis and Retrieval System Online (Medline), Scientific Electronic Library Online (SciELO), Web of Science and Science Direct databases was performed and nine observational studies associated with peripheral inflammatory biomarkers in MCI were identified. Mean (±standard deviation - SD) concentrations of these biomarkers and values of true positives, true negatives, false positives and false negatives for MCI and healthy controls (HC) were extracted from these studies. Results: Significantly higher levels of IL-10 were observed in subjects in the MCI group and Mini-Mental State Examination (MMSE) scores were lower compared to HC. For the other investigations, no differences were found between the groups. Our meta-analysis for the TNF-α biomarker revealed high heterogeneity between studies in terms of sensitivity and specificity. Conclusion: These findings do not support the involvement of inflammatory biomarkers for detection of MCI, although significant heterogeneity was observed. More studies are needed to evaluate the role of these cytokines in MCI, as well as in other stages of cognitive decline and all-cause dementias.

Há evidências crescentes que sugerem uma associação entre a neurodegeneração e a inflamação, desempenhando um papel na patogênese de doenças associadas à idade, incluindo a doença de Alzheimer (DA) e o comprometimento cognitivo leve (CCL). Objetivo: Uma revisão sistemática e metanálise foram realizadas para verificar evidências relativas aos parâmetros de acurácia diagnóstica das citocinas inflamatórias interleucina-6 (IL-6), interleucina-10 (IL-10) e fator de necrose tumoral (TNF-α). Métodos: Foi realizada uma busca nas bases de dados Medical Literature Analysis and Retrieval System Online (Medline), Scientific Electronic Library Online (SciELO), Web of Science e Science Direct, e foram identificados nove estudos observacionais associados a biomarcadores inflamatórios periféricos no CCL. As concentrações médias (desvio padrão ­ ±DP) desses biomarcadores e valores de verdadeiros positivos, verdadeiros negativos, falsos positivos e falsos negativos para CCL e controles saudáveis (CS) foram extraídos desses estudos. Resultados: Níveis significativamente mais elevados de IL-10 foram observados em indivíduos do grupo CCL e os escores do Miniexame do Estado Mental foram mais baixos em comparação com o CS. Para as demais investigações não foram encontradas diferenças entre os grupos. Nossa metanálise para o biomarcador TNF-α revelou alta heterogeneidade entre os estudos em termos de sensibilidade e especificidade. Conclusão: Esses achados não apoiam o envolvimento de biomarcadores inflamatórios na detecção do CCL, embora tenha sido observada heterogeneidade significativa. Mais estudos são necessários para avaliar o papel dessas citocinas no CCL, bem como em outros estágios de declínio cognitivo e demências de todas as causas.

Overview of the Metabolite Composition and Antioxidant Capacity of Seven Major and Minor Cereal Crops and Their Milling Fractions.

Cereal grains play an important role in human health as a source of macro- and micronutrients, besides phytochemicals. The metabolite diversity was investigated in cereal crops and their milling fractions by untargeted metabolomics ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) of 69 samples: 7 species (barley, oat, pearl millet, rye, sorghum, triticale, and wheat), 23 genotypes, and 4 milling fractions (husk, bran, flour, and wholegrain). Samples were also analyzed by in vitro antioxidant activity. UHPLC-MS/MS signals were processed using XCMS, and metabolite annotation was based on SIRIUS and GNPS libraries. Bran and husk showed the highest antioxidant capacity and phenolic content/diversity. The major metabolite classes were phenolic acids, flavonoids, fatty acyls, and organic acids. Sorghum, millet, barley, and oats showed distinct metabolite profiles, especially related to the bran fraction. Molecular networking and chemometrics provided a comprehensive insight into the metabolic profiling of cereal crops, unveiling the potential of coproducts and super cereals such as sorghum and millet as sources of polyphenols.

Contributions to a More Realistic Characterization of Corrosion Processes on Cut Edges of Coated Metals Using Scanning Microelectrochemical Techniques, Illustrated by the Case of ZnAlMg-Galvanized Steel with Different Coating Densities.

Corrosion processes at cut edges of galvanized steels proceed as highly localized electrochemical reactions between the exposed bulk steel matrix and the protective thin metallic coating of a more electrochemically active material. Scanning microelectrochemical techniques can thus provide the spatially resolved information needed to assess the corrosion initiation and propagation phenomena, yet most methods scan cut edge sections as embedded in insulating resin to achieve a flat surface for scanning purposes. In this work, the galvanized coatings on both sides of the material were concomitantly exposed to simulated acid rain while characterizing the cut edge response using SECM and SVET techniques, thereby maintaining the coupled effects through the exposure of the whole system as rather realistic operation conditions. The cut edges were shown to strongly promote oxygen consumption and subsequent alkalization to pH 10-11 over the iron, while diffusion phenomena eventually yielded the complete depletion of oxygen and pH neutralization of the nearby electrolyte. In addition, the cathodic activation of the exposed iron was intensified with a thinner coating despite the lower presence of sacrificial anode, and preferential sites of the attack in the corners revealed highly localized acidification below pH 4, which sustained hydrogen evolution at spots of the steel-coating interface.

Nanoremediation and Antioxidant Potential of Biogenic Silver Nanoparticles Synthesized Using Leucena's Leaves, Stem, and Fruits.

Synthetic dyes are persistent organic environmental pollutants that can cause extensive damage to living beings and to the ecosystem as a whole. Cost-effective, sustainable, and efficient strategies to deal with this type of pollution are necessary as it commonly resists conventional water treatment methods. Silver nanoparticles (AgNPs) synthesized using the aqueous extract from the leaves, stem, and fruits of Leucaena leucocephala (Leucena) were produced and characterized through UV-vis, TEM, EDS, SDL, XPS, XRD, and zeta potential, and they proved to be able to promote adsorption to remediate methylene blue and tartrazine pollution in water. The nanoremediation was performed and did not require direct exposure to sunlight or any special lamp or a specific reduction agent. The AgNPs produced using the extract from the leaves exhibited the best performance in nanoremediation and also presented antioxidant activity that surpassed the one from butylated hydroxytoluene (BHT). Consequently, it is an interesting nanotool to use in dye nanoremediation and/or as an antioxidant nanostructure.

[Effects of parliamentary amendments on municipal financing of primary health care in the Brazilian Unified National Health System]. / Efeitos das emendas parlamentares no financiamento municipal da atenção primária à saúde do Sistema Único de Saúde.

This study aims to analyze the effects of the expansion of the federal transfer of parliamentary amendments for municipal financing of primary health care (PHC) in the Brazilian Unified National Health System (SUS), from 2015 to 2020. A longitudinal study was conducted using secondary data on transfers of parliamentary amendments from the Brazilian Ministry of Health and expenditure of municipalities' own resources on public health actions and services and PHC. The effect of the transfer of parliamentary amendments on municipal financing was verified in a stratified way by population size of the municipalities, using generalized estimating equation models. The transfer of parliamentary amendments for PHC showed a large discrepancy in per capita values among municipalities of different population sizes. No correlation with municipal spending on public health actions and services was observed in municipalities with more than 10,000 inhabitants, and the association with spending on PHC (p < 0.050) was inverse in all municipalities. Therefore, the increase in the transfer of parliamentary amendments by the Brazilian Ministry of Health favored a reduction in the allocation of municipal revenues to PHC, which may have been directed to other spending purposes in the SUS. These changes seem to represent priorities established for municipal budget expenditure, which have repercussions on local conditions for guaranteeing stable funding for PHC in Brazil.

O objetivo deste artigo é analisar os efeitos da ampliação do repasse federal de emendas parlamentares no financiamento municipal da atenção primária à saúde (APS) do Sistema Único de Saúde (SUS), no período de 2015 a 2020. Foi realizado estudo longitudinal com dados secundários de transferências por emendas parlamentares do Ministério da Saúde e de despesas com recursos próprios dos municípios, aplicadas em ações e serviços públicos de saúde e na APS. O efeito do repasse de emendas parlamentares no financiamento municipal foi verificado de forma estratificada por porte populacional dos municípios, por meio de modelos de equações de estimativas generalizadas. O repasse de emendas parlamentares para a APS apresentou grande discrepância de valores per capita entre os municípios de diferentes portes populacionais. Observou-se inexistência de correlação com a despesa municipal em ações e serviços públicos de saúde nos municípios com mais de 10 mil habitantes e associação inversa com a despesa em APS (p < 0,050) em todos os grupos. Conclui-se que o aumento do repasse de emendas parlamentares pelo Ministério da Saúde favoreceu a redução da alocação de receitas municipais com APS, que podem ter sido direcionados para outras finalidades de gasto no SUS. Tais mudanças parecem refletir prioridades estabelecidas para a despesa orçamentária dos municípios, que repercutem sobre as condições locais para a garantia da estabilidade do financiamento da APS no Brasil.

Se concluye que el aumento en la transferencia de recursos de enmiendas parlamentarias por parte del Ministerio de Salud favoreció la reducción de la asignación de ingresos municipales a la APS, que pueden haber sido dirigidos a otros fines de gasto en el SUS. Tales cambios parecen reflejar prioridades establecidas para el gasto presupuestario municipal, que repercuten en las condiciones locales para garantizar la estabilidad del financiamiento de la APS en Brasil.

Characterisation of bioactive compounds from leaves of Smilax fluminensis Steud. by gc-MS and LC-DAD-MS, and analysis of its antioxidant and ecotoxicological activities.

Smilax fluminensis Steud. is distributed in Central and South America, commonly named as 'salsaparilha' or 'japicanga'. In the present work, the chemical composition was determined, antioxidant and cytotoxic effects were evaluated for the ethanol extract (EE) and fractions from leaves. Fatty acid esters and phytol were characterised in the hexane (HEX) fraction. O-glycosylated flavonols and flavones, caffeic acid derivatives, and steroidal saponins were annotated for EE, and dichloromethane (DCM), ethyl acetate (AC), and hydroethanol (HE) fractions. The samples contain flavonoids and phenolic compounds, and the AC fraction displayed the biggest concentration of these substances. Antioxidant potential was observed in all samples, being especially pronounced in the AC fraction by DPPH and FRAP assays, with IC50 values of 8.18 and 2.35 µg/mL, respectively. AC and HEX fractions showed 35% and 5% lethality at 1000 µg/mL, in the Artemia salina assay, and the other samples did not show a toxic effect.

Chemical characterization, antioxidant activity, and cytotoxicity of fatty acids methyl esters from Handroanthus impetiginosus (Mart. ex DC.) Mattos (Bignoniaceae) seeds.

Handroanthus impetiginosus, popularly known as "ipê-roxo", is used in folk medicine to treat skin inflammations, infections, stomach diseases, and cancer. Fatty acid methyl esters (FAMEs) obtained from the esterification reaction of fatty acids (FA) found in the hexane extract (HE) of seeds of H. impetiginosus were identified by gas chromatography-mass spectrometry (GC-MS). The antioxidant and cytotoxic activities of the HE and FAMEs were evaluated. Methyl palmitate, methyl linoleate, methyl oleate, and methyl stearate were the major FAMEs obtained from the HE. The samples, especially the HE, exhibited a significant antioxidant potential analyzed by ferric reducing ability power (FRAP) assay. In the A. salina larvae bioassay, the HE showed no cytotoxic effects, but the FAMEs exhibited a high toxicity. This study reported, for the first time, the antioxidant and cytotoxic activities of the HE and FAMEs obtained from H. impetiginosus seeds.

Abusive Consumption of Alcoholic Beverages and Associated Factors in Brazilian University Students.

The university is considered an environment that favors the initiation and use of substances, especially those that are legal, such as alcohol. This consumption can be differentiated in university students, which makes it necessary to better understand this behavior. Taking into account these aspects, we analyzed the abusive consumption of alcoholic beverages in university students and its association with socioeconomic and behavioral factors. We conducted a cross-sectional study with regularly enrolled students. We assessed the abusive consumption of alcoholic beverages using the binge drinking pattern. We collected socioeconomic and behavioral data using a questionnaire. The association between the variables was verified using logistic regression. Abusive consumption of alcoholic beverages was high, with a high weekly frequency. The association with sociodemographic and behavioral factors can increase the health risk. Education campaigns within institutions with students in the classroom and with all those who can influence these students are important. As there are few studies that consider other health risk factors that have not been analyzed yet, such as those treated in our study, with the abusive consumption of alcoholic beverages, this study seeks to contribute to the knowledge of the relationships between these variables and in the elaboration of actions aimed at improving the lifestyle and health of university students.

Vomiting after intrathecal chemotherapy under anesthesia in pediatric patients with hematologic cancers: A cohort study.

INTRODUCTION: Despite preventive strategies, vomiting is an adverse event affecting patients with cancer. However, literature on the incidence and risk factors for vomiting in pediatric patients with cancer are scarce. AIM: To assess the incidence and risk factors for vomiting within 24 h and goodness of fit for the Eberhart score in pediatric patients with hematologic cancers after receiving intrathecal chemotherapy under deep sedation. METHODS: This prospective cohort study included patients under 20 years of age with hematologic cancers who were scheduled to undergo intrathecal chemotherapy under anesthesia. The primary outcome was the occurrence of vomiting within 24 h after the end of anesthesia. Sociodemographic and procedure data and underlying diseases were collected. Patients were monitored during the procedure, in the postanesthesia care unit, and the day after (by phone call). RESULTS: A total of 139 patients were included, and the incidence of vomiting was 30.9% within 24 h after intrathecal chemotherapy under anesthesia, with 90.7% of vomiting prior to 6 h. Prophylactic ondansetron was administered prior to the procedure to 45.3% of patients. Risk factors for vomiting were female gender (hazard ratio: 2.47, 95% confidence interval: 1.35-4.53, p: .003), consolidation phase of treatment (hazard ratio: 2.16, 95% confidence interval: 1.10-4.24, p: .025), and history of kinetosis (hazard ratio: 2.49, 95% confidence interval: 1.31-4.70, p: .005). Incidence of vomit was higher than estimated by the Eberhart score distribution (observed incidence in patients with a score of zero: 33.3%; with a score of one: 28.8%; with a score of two: 60%). CONCLUSION: A high incidence of vomiting was observed within 24 h after intrathecal chemotherapy under propofol deep sedation. Risk factors for this outcome were established (being female, consolidation phase of treatment, and previous kinetosis), and evidence suggested that the Eberhart score was not suitable for the studied population.

Antinociceptive and anti-inflammatory potential, and chemical characterization of the dichloromethane fraction of Solanum lycocarpum (Solanaceae) ripe fruits by LC-DAD-MS.

ETHNOPHARMACOLOGICAL RELEVANCE: Solanum lycocarpum A. St. Hil. (Solanaceae) is a species from the Brazilian Cerrado, exhibiting several medicinal properties, being used by the population in the treatment of ulcers, bronchitis, asthma and hepatitis, which involve inflammatory processes. AIM OF THIS STUDY: This study aimed to chemically characterize the dichloromethane fraction (DCM), as well as verify its antinociceptive, anti-inflammatory and antioxidant potential. MATERIALS AND METHODS: The DCM fraction was obtained by partitioning the ethanol extract. The chemical constituents of the DCM fraction were characterized by LC-DAD-MS. The DPPH and FRAP assays were used to evaluate the antioxidant potential. The carrageenan-induced paw edema model was used to assess the anti-inflammatory effects, and the inflammatory infiltrate was evaluated by qualitative and quantitative histological analyses. The antinociceptive action of the DCM fraction was evaluated by acetic acid-induced abdominal writhing test, formalin-induced nociception and hot-plate test. RESULTS: Steroidal alkaloids solasonine, solasodine and solamargine, as well as the alkaloid peiminine/imperialine and caffeoylquinic acids, were annotated in DCM fraction by LC-DAD-MS. The DCM fraction showed antioxidative action in the in vitro DPPH and FRAP tests, as well as an anti-inflammatory effect for the three evaluated doses of 30, 100 and 300 mg/kg in the fourth and sixth hours after the administration of carrageenan. The histological analyses evidenced considerably reduction in leukocyte migration and the number of polymorphonuclear leukocytes. The study also demonstrated antinociceptive activity for the DCM fraction, which reduced abdominal writhing at three concentrations evaluated, as well as a decrease in paw licking in the formalin-induced nociception test both in the neurogenic phase and the inflammatory phase, with greater effectiveness compared to the anti-inflammatory indomethacin. The DCM fraction also increased the latency time of the animals in the hot plate test 60 min after treatment, although it did not seem to involve the opioidergic system. CONCLUSION: This work evidenced that the dichloromethane fraction of S. lycocarpum fruit possesses antinociceptive and anti-inflammatory potential, which supports its use in folk medicine for management inflammatory conditions.

Ocean-atmosphere turbulent CO2 fluxes at Drake Passage and Bransfield Strait.

The oceans play an important role in mitigating climate change by acting as large carbon sinks, especially at high latitude regions. The Southern Ocean plays a major role in the global carbon dioxide (CO2) budget. This work aims to investigate the behavior of turbulent CO2 fluxes and quantify it under different atmospheric and oceanic conditions in the Drake Passage and Bransfield Strait regions on high spatiotemporal resolutions when compared with traditional CO2 fluxes estimations. The atmospheric stability condition was used to corroborate the description of CO2 fluxes. In situ, satellite, and reanalysis data from 08 to 22 November 2018, were used in this work. The Bransfield Strait uptaked 38.59% more CO2 than the Drake Passage due to the cold and fresh waters, allied to the influence of glacial meltwater dilution. Which increased the CO2 solubility, directing the CO2 fluxes to the ocean. The Bransfield Strait had predominantly stable atmospheric conditions, which contributed to this region acting as a CO2 sink. The Drake Passage, on average, behaved as a CO2 sink, mainly due to physical characteristics. This research contributes to a better understanding of the Southern Ocean's role in the global carbon balance on scales that are very difficult to monitor.

Role of short germination and milling on physical properties, amino acid and metabolomic profiles of high amylose rice fractions.

Short germination is a process that can improve bioactive compounds in rice. This work aimed investigate the physical properties, phenolic compounds (PC), antioxidant activity and amino acids composition of husk + bran, brown and milled rice with high amylose content after short germination (16 h). α-amylase activity (Falling Number, FN) and enthalpy (ΔH) were unchanged (p < 0.05). RVA curve profiles were similar, even though after short germination and milling. Globally, metabolomics analysis identified 117 PC, in which 111 (bound), 104 (free) and 21 revealed in both extracts. p-Coumaric, trans-ferulic and ferulic acids were the most abundant PC revealed in all fractions. The portion husk + bran showed the highest level of total antioxidant activity (709.90 µmol TE) in both free and bound fractions. In terms of total amino acids, there was no statistical difference (p < 0.05) among non-germinated and germinated samples, contrary to free amino acids content. Glutamic acid (Glu) presented the highest values combining short germination and milling (1725-1900 mg/100 g) consequently, leads to higher value of GABA (12.21 mg/100 g). The combination of short germination and milling demonstrated a good strategy to improve the nutritional quality of rice, unless the thermal and pasting properties have been altered, contribute to potential health benefits on human nutrition.
