RESUMEN

Humoral response to SARS-CoV-2 has been studied, predominantly the classical IgG and its subclasses. Although IgE antibodies are typically specific to allergens or parasites, a few reports describe their production in response to SARS-CoV-2 and other viruses. Here, we investigated IgE specific to receptor binding domain (RBD) of SARS-CoV-2 in a Brazilian cohort following natural infection and vaccination. Samples from 59 volunteers were assessed after infection (COVID-19), primary immunization with vectored (ChAdOx1) or inactivated (CoronaVac) vaccines, and booster immunization with mRNA (BNT162b2) vaccine. Natural COVID-19 induced IgE, but vaccination increased its levels. Subjects vaccinated with two doses of ChAdOx1 exhibited a more robust response than those immunized with two doses of CoronaVac; however, after boosting with BNT162b2, all groups presented similar IgE levels. IgE showed intermediate-to-high avidity, especially after the booster vaccine. We also found IgG4 antibodies, mainly after the booster, and they moderately correlated with IgE. ELISA results were confirmed by control assays, using IgG depletion by protein G and lack of reactivity with heterologous antigen. In our cohort, no clinical data could be associated with the IgE response. We advocate for further research on IgE and its role in viral immunity, extending beyond allergies and parasitic infections.

RESUMEN

The study evoluated an in-house Spike Receptor Binding Domain Enzyme-Linked Immunosorbent Assay (RBD-IgG-ELISA) for detecting SARS-CoV-2 IgG antibodies in infected and vaccinated individuals. The assay demonstrated a sensitivity of 91%, specificity of 99.25%, and accuracy of 95.13%. Precision and reproducibility were highly consistent. The RBD-IgG-ELISA was able to detect 96.25% of Polymerase chain reaction (PCR) confirmed cases for SARS-CoV-2 infection, demonstrating positive and negative predictive values of 99,18% and 91,69%, respectively. In an epidemiological survey, ELISA, lateral flow immunochromatographic assay (LFIA), and electrochemiluminescence immunoassay (ECLIA) exhibited diagnostic sensitivities of 68.29%, 63.41%, and 70.73%, respectively, along with specificities of 82.93%, 80.49%, and 80.49%, respectively. Agreement between RBD-IgG-ELISA/PCR was moderate (k index 0.512). However, good agreement between different assays (RBD-IgG-ELISA/LFIA k index 0.875, RBD-IgG-ELISA/ECLIA k index 0.901). Test performance on individuals' samples were inferior due to seroconversion time and chronicity. The IgG-RBD-ELISA assay demonstrated its effectiveness in monitoring antibody levels among healthcare professionals, revealing significant differences both before and after the administration of the third vaccine dose, with heightened protection levels observed following the third dose in five Coronavirus disease (COVID-19) vaccine regimens. In conclusion, the RBD-IgG-ELISA exhibits high reproducibility, specificity, and sensitivity, making it a suitable assay validated for serosurveillance and for obtaining information about COVID-19 infections or vaccinations.

RESUMEN

Sarcopenia, a clinical syndrome primarily associated with reduced muscle mass in the elderly, has a negative impact on quality of life and survival. It can occur secondarily to other diseases such as heart failure (HF), a complex clinical syndrome with high morbidity and mortality. The simultaneous occurrence of these two conditions can worsen the prognosis of their carriers, especially in the most severe cases of HF, as in patients with reduced left ventricular ejection fraction (LVEF). However, due to the heterogeneous diagnostic criteria for sarcopenia, estimates of its prevalence present a wide variation, leading to new criteria having been recently proposed for its diagnosis, emphasizing muscle strength and function rather than skeletal muscle mass. The primary objective of this study is to evaluate the prevalence of sarcopenia and/or dynapenia in individuals with HF with reduced LVEF according to the most recent criteria, and compare the gene and protein expression of those patients with and without sarcopenia. The secondary objectives are to evaluate the association of sarcopenia and/or dynapenia with the risk of clinical events and death, quality of life, cardiorespiratory capacity, ventilatory efficiency, and respiratory muscle strength. The participants will answer questionnaires to evaluate sarcopenia and quality of life, and will undergo the following tests: handgrip strength, gait speed, dual-energy X-ray absorptiometry, respiratory muscle strength, cardiopulmonary exercise, as well as genomic and proteomic analysis, and dosage of N-terminal pro-B-type natriuretic peptide and growth differentiation factor-15. An association between sarcopenia and/or dynapenia with unfavorable clinical evolution is expected to be found, in addition to reduced quality of life, cardiorespiratory capacity, ventilatory efficiency, and respiratory muscle strength.

RESUMEN

ETHNOPHARMACOLOGY RELEVANCE: Commiphora leptophloeos (Mart.) J.B. Gillet (Burseraceae) is a medicinal plant native to Brazil, popularly known as "imburana". Homemade leaf decoction and maceration were used to treat general inflammatory problems in the Brazilian Northeast population. Our previous research confirmed the anti-inflammatory activity of the C. leptophloeos hydroalcoholic leaf extract. AIM OF THE STUDY: Inflammatory bowel disease (IBD) is a chronic and relapsing inflammatory disorder of the gut with no ideal treatment to maintain the remissive status. This work aimed to characterize the phytochemical composition and physicochemical properties of the C. leptophloeos hydroalcoholic leaf extract and its efficacy in chemopreventive and immunomodulatory responses in inflammatory bowel disease in non-clinical models. MATERIALS AND METHODS: Mass spectrometry and physicochemical tests determined the phytochemical profile and physicochemical characteristics of the Commiphora leptophloeos (CL) extract. The chemopreventive and immunomodulatory effects of CL extract (50 and 125 µg/mL) were evaluated in vitro in the RAW 264.7 lipopolysaccharide (LPS) induced cell assay and in vivo in the model of intestinal inflammation induced by 2,4-Dinitrobenzenesulfonic acid (DNBS) in mice when they were treated with CL extract by intragastric gavage (i.g.) at doses of 300, 400 and 500 mg/kg. RESULTS: Phytochemical annotation of CL extract showed a complex phenolic composition, characterized as phenolic acids and flavonoids, and satisfactory physicochemical characteristics. In addition, CL extract maintained the viability of RAW macrophages, reduced ROS and NO production, and negatively regulated COX-2, iNOS, TNF-α, IL-1ß, IL-6, and IL-17 (p < 0.05). In the intestinal inflammation model, CL extract was able to downregulate NF-κB p65/COX-2, mTOR, iNOS, IL-17, decrease levels of malondialdehyde and myeloperoxidase and cytokines TNF-α, IL-1ß and IL-6 (p < 0.05). CONCLUSION: Based on these findings, CL extract reduced inflammatory responses by down-regulating pro-inflammatory markers in macrophages induced by LPS and DNBS-induced colitis in mice through NF-κB p65/COX-2 signaling. CL leaf extract requires further investigation as a candidate for treating inflammatory bowel disease.

RESUMEN

Resumo Objetivo refletir sobre a possibilidade de utilização dos pressupostos de Imogene King como fundamentação teórica para os cuidados de enfermagem a parceiros sexuais sorodiferentes ao HIV. Método estudo descritivo de caráter reflexivo, com o aporte teórico da Teoria do Alcance de Metas de Imogene King. Resultados as reflexões deram origem a dois eixos de análise: no primeiro, cumpre-se detalhar os pressupostos conceituais de Imogene King e o alcance de metas, e no segundo, explora-se a convergência da teoria de King no cuidado às relações sorodiferentes no que concerne aos seus limites, possibilidades e desdobramentos nos sistemas pessoal, interpessoal e social. Conceitos como percepção, interação e organização formam os eixos centrais dos sistemas e possibilitam a compreensão ampliada das demandas dos parceiros sorodiferentes com vistas ao equilíbrio dos fatores estressores à manutenção da saúde. Considerações finais e implicações para a prática o entendimento dos sistemas abertos aplicados à pessoa que vive com HIV individualmente e na díade com seu parceiro, ambos inseridos em grupos na sociedade, resulta em uma melhor compreensão de suas necessidades e, assim, contribuem com o planejamento de metas direcionadas.

Abstract Objective to reflect on the possibility of using Imogene King's assumptions as a theoretical basis for nursing care in HIV-serodifferent partnerships. Method a descriptive study of a reflective nature, with the theoretical contribution of Imogene King's Goal Attainment Theory. Results the reflections gave rise to two axes of analysis: in the first, it is necessary to detail Imogene King's conceptual assumptions and goal attainment, and in the second, the convergence of King's theory in caring for serodifferent relationships is explored with regard to their limits, possibilities and developments in the personal, interpersonal and social systems. Concepts such as perception, interaction and organization form the central axes of the systems and enable a broader understanding of serodifferent partners' demands with a view to balancing stress factors for maintaining health. Final considerations and implications for practice the understanding of open systems applied to people living with HIV individually and in a dyad with their partner, both inserted in groups in society, results in a better understanding of their needs and thus contributes to planning targeted goals.

RESUMEN

BACKGROUND: Discarding pharmaceuticals in the garbage or into the sewage system are still the most common methods in many countries. This study aims to investigate the guidance provided by pharmacists to customers on the disposal of unused and expired household medications in São Paulo State, Brazil. METHOD: The study population consisted of 630 pharmacists from the State of São Paulo, who work in community pharmacies. They answered an online questionnaire with questions composed in three blocks: demographic, work, and academic information on the pharmacist; guidance about the disposal of household medications; and knowledge regarding the reverse logistics of these medications. An invitation to participate in the questionnaire was made via WhatsApp, individually and collectively. Inferential statistics were performed using the chi-square test and were considered significant when p < 0.05%. RESULTS: Among the participating pharmacists, the majority were women under 60 years old,56 (8.89%) stated that they never orient the customer regarding the disposal of unused and expired household medications, while 574 (91,12%) indicated that they almost provide guidance. The frequency with which they provided guidance was influenced by the number of years since graduation (p = 0.0047), the time they had worked in pharmacies and drugstores (p = 0.0007), and whether or not they had a graduate degree (p = 0.0181). Regarding the disposal of medications, among the 643 responses provided by the pharmacists,516 (80.25%) indicated that they oriented customers to return them to a pharmacy. CONCLUSION: A small number of pharmacists always orient customers on the proper disposal that should be followed for unused and expired household medications, prioritizing their return to a pharmacy. In general, these pharmacists have longer periods of work experience and higher academic qualifications. Thus, it is important to increase knowledge through professional training and further education programs.

RESUMEN

Lentinula edodes, commonly known as shiitake mushroom, is renowned for its potential health advantages. This research delves into the often-overlooked by-product of shiitake cultivation, namely spent mushroom substrate (SMS), to explore its nutraceutical properties. The SMS samples were collected and subjected to different extraction methods, namely short or long agitation, and ultrasound-assisted extractions using different temperatures and distilled water or a 50% (v/v) ethanol as solvents. The extracts were tested for phenolic content (total phenols, ortho-diphenols, and flavonoids), antioxidant capacity (DPPH, 2,2-diphenyl-1 picrylhydrazyl; ABTS, 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid; and FRAP, ferric reducing antioxidant power), and antibacterial activity. The different extraction methods revealed substantial variations (p < 0.05) in phenolic composition and antioxidant capacity. The highest phenolic content and antioxidant capacity were achieved using 24 h extraction, agitation, 50 °C, and ethanol as the solvent. Furthermore, the extracted compounds displayed antibacterial activity in specific tested bacterial strains. This study highlights the nutraceutical potential of L. edodes' SMS, positioning it as a valuable dietary supplement for animal nutrition, with emphasis on its prebiotic properties. Hence, this research unveils the promising health benefits of SMS in both human and animal nutrition.

RESUMEN

The present study investigated the effect of gelatin-based nanoparticles (EPG) loaded with a carotenoid-rich crude extract (CE) on systemic and adipose tissue inflammatory response in a model with inflammation induced by a high glycemic index and high glycemic load diet (HGLI). Nanoparticles synthesized were characterized by different physical and chemical methods. The in vivo investigation evaluated Wistar rats (n = 20, 11 days, adult male with 21 weeks) subdivided into untreated (HGLI diet), conventional treatment (nutritionally adequate diet), treatment 1 (HGLI + crude extract (12.5 mg/kg)), and treatment 2 (HGLI + EPG (50 mg/kg)) groups. Dietary intake, caloric intake and efficiency, weight, inflammatory cytokines tissue concentration, visceral adipose tissue (VAT) weight, histopathological analysis, and antioxidant activity in plasma and VAT were investigated. EPG showed the same physical and chemical characteristics as previous batches (95.2 nm, smooth surface, and chemical interactions between materials). The EPG-treated group was the only group promoting negative ∆dietary intake, ∆caloric efficiency, and ∆weight. In addition, it presented a significant reduction (p < 0.05) in IL-6 and leptin levels and a greater presence of multilocular adipocytes. The results suggest that EPG can act as a nutraceutical in adjuvant therapy for treating inflammatory diseases associated with adipose tissue accumulation.

RESUMEN

Obesity in adolescents has reached epidemic proportions and is associated with the inflammatory response and viral infections. The aim of this study was to understand the profile of inflammatory cytokines and chemokines associated with the inflammatory response and metabolic syndrome (MetS) in obese adolescents with positive serology for adenovirus 36 (ADV36). Thirty-six overweight, 36 obese, and 25 severe obesity adolescents aged 10 to 16 years were included in the study. The following variables were analyzed: sex, age, body mass index (BMI), blood pressure, total cholesterol and fractions, triglycerides, glucose, serum cytokine concentrations, and ADV36 antibodies. Cytokines and chemokines were quantified by cytometry and ADV36 serology was determined by enzyme-linked immunosorbent assay (ELISA). The results showed higher levels of the cytokines interleukin-1beta (IL-1ß), IL-6, IL-10 and of the chemokine interferon-gamma-inducible protein 10 (IP-10) in severe obesity adolescents compared to the obese and overweight groups, as well as in the group with MetS compared to the group without this syndrome. The frequency of ADV36-positive individuals did not differ between groups. The findings revealed differences in BMI between the obese and severe obesity groups versus the overweight group in the presence of positivity for ADV36, suggesting an association with weight gain and possibly MetS installation.

RESUMEN

Donkey milk (DM) is a source of bioactive compounds that can benefit neural functioning. In the present study, we investigated the effects of DM consumption on anxiolytic-related, despair-like, locomotion and coordination behaviors, as well as the provision of protection from oxidative damage to lipids and proteins in brain tissues and melatonin plasma levels. To achieve this, male mice orally received DM (4 g.kg-1) or vehicle for 18 days. Their behavior was assessed in the following tests: elevated plus maze (EPM), open field and rotarod tests (OF, RR) and forced swimming test (FST). Acute treatments with diazepam (DZP, 1.5 mg.kg-1, v.o.), fluoxetine (FLX, 20 mg.kg-1, i.p.) and nortriptyline (NTP, 20 mg.kg-1, i.p.) were used as positive controls. On the eighteenth day, the animals were euthanized and brain tissue and blood were collected to measure oxidative damage, and melatonin plasma levels. Similar to DZP, repeated DM consumption reduced exploration to open areas in the EPM test. Under our experimental conditions, conventional antidepressants reduced immobility time in the FST, and the benzodiazepine treatment impaired motor coordination in mice. No significant differences in locomotion, motor coordination and despair-related behaviors were observed in the mice treated with DM when assessed in the EPM, OF, RR and FST, respectively. Biochemical assays showed that repeated DM exposition protected against oxidative damage to lipids and increased plasma levels of melatonin. These findings suggest consumption of DM may be a promising food for the treatment of anxiety-related disorders, without depressant effects on the central nervous system.

RESUMEN

PURPOSE: This systematic review aimed to evaluate the benefits and harms of fibrate therapy, alone or in combination with statins, in adult patients with type 2 diabetes (T2D). METHODS: A comprehensive search was conducted in six databases, from inception to January 27, 2022. Clinical trials that compared fibrate therapy with other lipid-lowering interventions or placebo were included. Outcomes of interest comprised cardiovascular (CV) events, complications of T2D, metabolic profile, and adverse events. Random-effects meta-analyses were performed to estimate mean differences (MD) and risk ratios (RR), alongside 95% confidence intervals (CI). RESULTS: A total of 25 studies were included, six comparing fibrates against statins, 11 against placebo, and eight evaluating the combination of fibrates with statins. Overall risk of bias was rated as moderate, and most outcomes rendered low confidence per GRADE approach. Fibrates showed reduction of serum triglycerides (TGs) (MD -17.81, CI -33.92 to -1.69) and a marginal increase of high-density lipoprotein cholesterol (HDL-c) (MD: 1.60, CI 0.29 to 2.90) in adults with T2D, but no differences were found in CV events when compared to statin therapy (RR 0.99, CI 0.76 to 1.09). When used in combination with statins, no major differences were exhibited regarding lipid profile and CV outcomes. Adverse events were comparable between fibrate and statin monotherapies (e.g., RR of 1.03 for rhabdomyolysis, and 0.90 for gastrointestinal events). CONCLUSIONS: Fibrate therapy in patients with T2D results in a marginal improvement of TGs and HDL-c but without reducing the risk of CV events and mortality. Their use should be reserved for very specific scenarios after a deliberative dialogue between patients and clinicians regarding their benefits and harms.

RESUMEN

The subgenus Edessa, the largest and to date the most confusing taxon of Edessa is diagnosed here, comprising 79 species listed in this work. The subgenus is characterized by the humeral angles conical, somewhat developed, and projected, with apex rounded or somewhat acuminated, but never acute, shyny and impunctate or with a few punctures. The E. sexdens group, composed of 22 species, is proposed here to the subgenus Edessa. This group can be characterized by the anterior arms of the metasternal process with excavated apex; connexival segments with a pair of dark spots; ventral side of the abdomen raised medially; rounded shallow excavation near each spiracle; area between dorsal rim of the pygophore and posterolateral angles grooved; superior process of the genital cup laminar and continued ventrally by a carina, oblique to the parameres; parameres with three lobes; area between dorsal rim of the pygophore and posterolateral angles grooved. The species of the E. sexdens group are distributed in the Neotropical region, from Mexico to Argentina. Descriptions, measurements, and illustrations are provided. An identification key and distributional map are presented. The species Edessa suturata Dallas, 1851 is considered junior synonym of E. alces Erichson, 1848; E. inclyta Walker, 1868, E. fuscidorsata Distant, 1881, and E. gnu Breddin, 1905 are considered junior synonyms of E. electa Walker, 1868; E. olivacea Stål, 1862 and E. ventralis Walker, 1868 are considered junior synonym of E. phoenicopus Dallas, 1851; E. nigromarginata Distant, 1881 is considered junior synonym of E. sexdens Fabricius, 1803; E. subandina Breddin, 1994 is considered a valid species; Edessa dentata (Dallas, 1851) and Edessa excellens (Walker, 1868) are considered junior synonym of E. (E.) urus Erichson, 1848.

RESUMEN

OBJECTIVE: To understand the meaning attributed by women to the use of their own voice in labor. METHOD: Descriptive qualitative study based on the theoretical-philosophical-methodological framework of Heidegger. Phenomenological interviews were carried out with 20 women who experienced vaginal delivery without interventions in the second quarter of 2020 in the city of Rio de Janeiro - Brazil. RESULTS: The comprehensive analysis revealed that the voice can provoke a reaction from the environment that makes them suffer. The expression of the voice encompasses fear and despair. It is from what they hear that women fear being left in suffering for havingbothered the professionals. CONCLUSION: The meaning of using one's own voice in childbirth was understood as a request for help or an expression of freedom. Based on this understanding, the professionals can be opened to sensitive and individualized care, which goes beyond technology.

RESUMEN

Nopalea cochenillifera (Cactaceae), popularly known as "palma" or "palma doce", is from Mexico, but it was widely introduced in Brazil through crops. It has been used as food and in traditional medicine and is a good source of phenolic compounds. In this study the phytochemical profile and gastroprotective activity of phenolic-rich extract of N. cochenillifera in acute gastric lesion models induced by ethanol and indomethacin were evaluated. High-performance liquid chromatography coupled with mass spectrometry (HPLC/ESI/MSn) allowed the characterization of 12 compounds such as sugars, phenolics and flavonoids. Among polyphenols, the main peak was assigned to isorhamnetin-3-O-(2'',3''-O-di-rhamnose)-glucoside. The TPC and TFC in the dry extract were 67.85 mg of gallic acid equivalent per g/extract and 46.16 mg quercetin equivalent per g/extract, respectively. In the in vitro MTT assay, the extract showed no cytotoxicity and suppressed ROS levels in LPS-treated RAW 264.7 cells. Preclinical models in rats showed that a dose of 100 mg kg-1 (p < 0.0001) in the ethanol model and doses of 100 mg kg-1 (p < 0.5) and 200 mg kg-1 (p < 0.01) in the indomethacin model reduced the gastric lesions. Also, the extract reduced the MPO, MDA, TNF-α and IL-1ß levels and increased the GSH and IL-10 levels. The pre-treatment with the extract led to the upregulation of SOD and the downregulation of COX-2 by immunohistochemical analysis. It also showed a cytoprotective effect in the histopathological analysis and stimulated the restoration of the mucus content as observed in the periodic acid-Schiff analysis without modifying the pH, volume or total acidity of the gastric juice. Taken together, N. cochenillifera extract can be applied as a novel gastroprotective ingredient for food or pharmaceutical products.

RESUMEN

Phenolic compounds have been scientifically recognized as beneficial to intestinal health. The cactus Nopalea cochenillifera, used as anti-inflammatory in traditional medicine, is a rich source of these bioactive compounds. The present study aimed to investigate the phytochemical profile of N. cochenillifera extract and evaluate its acute toxicity and anti-inflammatory effect on 2,4-dinitrobenzenesulfonic acid (DNBS)-induced colitis in rats. The total phenolic content per gram of dry extract was 67.85 mg. Through HPLC-IES-MSn, a total of 25 compounds such as saccharides, organic acids, phenolic acids and flavonoids were characterized. The dose of 2000 mg/kg of extract by an oral route showed no signs of toxicity, mortality or significant changes in biochemical and hematological parameters. Regarding intestinal anti-inflammatory effects, animals were treated with three different doses of extract or sulfasalazine. Macroscopic analysis of the colon indicated that the extract decreased the disease activity index. Levels of IL-1ß and TNF-α decreased, IL-10 increased and MDA and MPO enzyme levels decreased when compared with the control group. In addition, a down-regulation of MAPK1/ERK2 and NF-κB p65 pathway markers in colon tissue was observed. The epithelial integrity was improved according to histopathological and immunohistological analysis. Thus, the extract provided strong preclinical evidence of being effective in maintaining the remission of colitis.

RESUMEN

Landscape dynamics are widely thought to govern the tempo and mode of continental radiations, yet the effects of river network rearrangements on dispersal and lineage diversification remain poorly understood. We integrated an unprecedented occurrence dataset of 4,967 species with a newly compiled, time-calibrated phylogeny of South American freshwater fishes-the most species-rich continental vertebrate fauna on Earth-to track the evolutionary processes associated with hydrogeographic events over 100 Ma. Net lineage diversification was heterogeneous through time, across space, and among clades. Five abrupt shifts in net diversification rates occurred during the Paleogene and Miocene (between 30 and 7 Ma) in association with major landscape evolution events. Net diversification accelerated from the Miocene to the Recent (c. 20 to 0 Ma), with Western Amazonia having the highest rates of in situ diversification, which led to it being an important source of species dispersing to other regions. All regional biotic interchanges were associated with documented hydrogeographic events and the formation of biogeographic corridors, including the Early Miocene (c. 23 to 16 Ma) uplift of the Serra do Mar and Serra da Mantiqueira and the Late Miocene (c. 10 Ma) uplift of the Northern Andes and associated formation of the modern transcontinental Amazon River. The combination of high diversification rates and extensive biotic interchange associated with Western Amazonia yielded its extraordinary contemporary richness and phylogenetic endemism. Our results support the hypothesis that landscape dynamics, which shaped the history of drainage basin connections, strongly affected the assembly and diversification of basin-wide fish faunas.

RESUMEN

RESUMO Objetivo comparar as características populacionais e assistenciais de adesão ao contato imediato entre mãe e recém-nascido na primeira hora de vida em duas maternidades públicas de risco habitual. Métodos trata-se de um estudo transversal, do qual participaram 105 mães que tiveram parto normal e seus respectivos recém-nascidos na primeira hora de vida em duas maternidades com unidades de Pré-parto, Parto e Puerpério. Para a pesquisa, utilizou-se um instrumento com 36 questões baseadas nas Diretrizes Nacionais de Assistência ao Parto Normal. A análise foi baseada no teste Qui-quadrado de homogeneidade e teste Exato de Fisher, para comparar a assistência prestada nas maternidades. Resultados ambas as maternidades atenderam aos binômios de risco habitual. Quanto à assistência prestada, apenas a maternidade federal promoveu o incentivo ao contato imediato entre mãe e recém-nascido na primeira hora de vida, além de favorecer 7,1% (n=3) dos binômios com a hora dourada de forma correta e significativa (p=0,037). Conclusão apesar da similaridade do perfil da assistência, apenas uma maternidade realizou a hora dourada, sendo necessária a inserção das boas práticas nas maternidades. Contribuições para a prática por meio da observação direta da assistência prestada ao binômio, identificaram-se lacunas no formato e durabilidade do contato imediato nas maternidades.


ABSTRACT Objective to compare population and care characteristics of adherence to immediate contact between mother and newborn in the first hour of life in two public maternity hospitals at usual risk. Methods cross-sectional study with 105 mothers after normal delivery and their respective newborns in the first hour of life in two maternity hospitals with Prepartum, Labor, and Puerperium units. We used an instrument with 36 questions based on the National Guidelines of Assistance to Normal Birth. Analysis was based on the chi-square test for homogeneity and Fisher's exact test to compare the assistance provided in maternity hospitals. Results both maternity hospitals attended the usual risk binomials. Regarding the assistance provided, only the federal maternity promoted encouragement of immediate contact between mother and newborn in the first hour of life, besides favoring 7.1% (n=3) of the binomials with the golden hour in a correct and significant way (p=0.037). Conclusion despite the similarity of the assistance profile, only one maternity hospital performed the golden hour, being necessary the insertion of good practices in maternity hospitals. Contributions to practice direct observation of the assistance provided to binomial identified gaps in the format and durability of the immediate contact in maternity hospitals.
