RESUMO

PURPOSE: To assess hospitalized children's satisfaction with nursing care. DESIGN AND METHODS: Cross-sectional study using the "Children Care Quality at Hospital" questionnaire. 61 children admitted to the Pediatrics Department of a hospital in the Northern Region of Portugal were enrolled. RESULTS: The ranged age of the participants was 6 to 15 (10,61 ± 2,66 years), and most were male (52.46%; n = 32). The mean score in the three domains was 128 (77.11%), reflecting children's high satisfaction with the nursing care provided during hospitalization. The domain most valued was Nurse Characteristics, while the least valued was Nursing Environment. CONCLUSION: Results provide essential input for the dimensions to be considered when planning nursing care for children, managing care, and the physical environment in the wards. IMPLICATIONS FOR PRACTICE: These results highlight the need to hear children's voices. This must encourage nurses to reflect on how children evaluate nursing care and, by doing so, to increase the quality of nursing care provided in Pediatrics settings.

RESUMO

The contents of essential (Ca, Fe, K, Na, P, and Zn) and potentially toxic inorganic elements (As, Al, Cd, Cr, Cu, Mn, and Pb) in enteral and parenteral nutrition formulas were evaluated by inductively coupled plasma optical emission spectrometry (ICP OES) and graphite furnace atomic absorption spectrometry (GFAAS). A total of 30 enteral formulas, 23 parenteral solution components, and 3 parenteral solutions were analyzed. The elements Ca and K presented the higher contents (72-2918 mg L-1 and 235-2760 mg L-1) while the lowest concentration levels were found for As and Cd (<0.68 µg L-1 and <0.01-0.62 µg L-1) in the studied samples. The validated analytical methods presented an accuracy of 75-116% and RSD values lower than 9.8%. Calcium gluconate and magnesium sulfate, which are used as raw materials in parenteral solution, are potential sources of Al and Mn contamination. A Hazard Quotient (HQ) >1 was obtained for Al (27 ± 1 µg L-1) in one of the parenteral samples, whereas the established limit is 25 µg L-1. Enteral samples were considered safe for consumption regarding the Al, As, and Cd levels. One healing-specific and pediatric formula contained Pb at levels above 0.25 µg kg-day-1, too high for safe consumption. The enteral formulas (pediatric, diabetes-specific, renal-specific, healing-specific, and standard formula with addition of fiber) presented risks in relation to the consumption of Cr and Mn (>250 µg day-1 and >11 mg day-1). The results indicate the need for strict monitoring, considering that these formulations are often the single patient's food source.

RESUMO

INTRODUCTION: Clinical trials on tyrosine kinase inhibitors (TKI) treatment have shown an improvement in overall and progression-free survival in patients with advanced differentiated thyroid cancer. However, it is necessary to evaluate these studies to assess methodological biases and inconsistencies that may impact the effects. OBJECTIVE: To map and assess the methodological quality of randomized clinical trials (RCTs) regarding randomization, allocation concealment, blinding, and selective reporting bias. METHODS: RCTs assessing the efficacy and safety of TKI for the treatment of advanced differentiated thyroid cancer were included. The search was performed in the MEDLINE database. The included RCTs were assessed for the adequacy of the methodological steps, as recommended by the Cochrane Risk of Bias tool. RESULTS: Nine studies were analyzed, of which 77.7% were classified as low risk of bias regarding selective reporting and 33.3% as high risk of reporting bias. The mean time between protocol registration and study publication was approximately 5.11 years. Moreover, 66.7% were classified as low risk of bias for randomization and allocation concealment, and 33.3% did not specify the randomization process and allocation concealment in a way that would allow the identification of occurrences of bias. Concerning blinding of participants and outcome assessors, 77.8% of the RCTs reported adequate blinding and were classified as having a low risk of bias, 11.1% had a high risk of bias, and 11.1% had insufficient information and were classified as having unclear risk of bias. Regarding the blinding of the outcome assessors, 33.3% did the blinding correctly, 11.1% did not blind, and 55.6% did not provide enough information. CONCLUSION: Overall, the assessed RCTs were predominantly at low risk of bias. The critical evaluation of these studies is essential to have confidence in the treatment estimated effect that will support clinical decision-making and provide information to preclude future clinical study flaws.

RESUMO

Bioaccumulation studies in fish mark the initial phase of assessing the risk of chemical exposure to biota and human populations. The Iguaçu River boasting a diverse endemic ichthyofauna, is grappling with the repercussions of human activities. This study delved into the bioaccumulation of micropollutants, the early-warning effects on Rhamdia quelen and Oreochomis niloticus in the Segredo Reservoir (HRS) and the potential risk of human exposure. Two groups of caged fish in three sites of the reservoir were exposed during the autumn-winter and spring-summer, while a third group (O. niloticus) underwent a twelve-month exposure, and inorganic and organic chemicals analysis in water, sediment, and biota. Additionally, metallothionein expression and genotoxicity were employed as biomarkers. PAHs, PCBs, Al, Cu, Fe, and As in water and DDTs, Cu, Zn, and As in sediment surpassed the thresholds set by Brazilian regulations, where DDT exhibited bioaccumulation in muscle, alongside metals in liver, kidney, gills, and muscle tissues. R. quelen showed metallothionein expression whereas DNA damage and NMA frequencies were elevated in target organs and in brain and erythrocytes of O. niloticus during summer. In this species the DNA damage in liver was remarkable after twelve months. Target Hazard Quotients and Cancer Risk values shedding light on the vulnerability of both children and adults. The reservoir's conditions led to heightened sensitivity to micropollutants for R. quelen species. The data presented herein provides decision-makers with pertinent insights to facilitate effective management and conservation initiatives within the Iguaçu Basin.

RESUMO

OBJECTIVE: This study aims to describe and compare the prevalence of perceived barriers to physical activity (PBPA) in pre- and post-metabolic and bariatric surgery (MBS) patients and assess the association of these barriers with their physical activity levels. METHODS: A cross-sectional study included pre-operative (n = 63) and post-operative (n = 119) groups. Sociodemographic characteristics, leisure-time physical activity levels, and PBPA data were collected. Descriptive statistics, chi-square, and Fisher's exact tests, and binomial logistic regression analyses were used for comparisons and associations. RESULTS: Compared to the pre-operative group, the post-operative group had a lower prevalence of barriers in the physical domain (p = 0.036) and the behavioral domain (p = 0.004). However, there were no significant differences in the environmental (p = 0.531) or social (p = 0.597) domains. Pre-MBS patients were more likely to be physically inactive when perceiving barriers in the environmental (p = 0.048) and behavioral (p = 0.048) domains. In contrast, post-surgical patients were more likely to be physically inactive when perceiving barriers in the environmental (p = 0.027), social (p = 0.020), and behavioral (p = 0.037) domains. CONCLUSION: The results show that individuals who underwent metabolic and bariatric surgery have a lower prevalence of behavioral and physical PBPA compared to those awaiting the procedure. The perception of barriers to physical activity in the environmental and behavioral domains increases the likelihood of physical inactivity in both pre- and post-MBS patients, while in the social domain, it was only associated with physical activity in post-MBS patients.

RESUMO

Introduction: Vagus nerve stimulation (VNS) therapy is an established treatment for patients with drug-resistant epilepsy that reduces seizure frequency by at least 50% in approximately half of patients; however, the characteristics of the patients with the best response have not yet been identified. Thus, it is important to identify the profile of patients who would have the best response to guide early indications and better patient selection. Methods: This retrospective study evaluated vagus nerve stimulation (VNS) as an adjuvant therapy for patients with drug-resistant epilepsy from six epilepsy centers in Brazil. Data from 192 patients aged 2-66 years were analyzed, and all patients received at least 6 months of therapy to be included. Results: Included patients were aged 2-66 years (25.6 ± 14.3), 105 (54.7%) males and 87 (45.8%) females. Median follow-up interval was 5 years (range, 2005-2018). Overall, the response rate (≥50% seizure reduction) after VNS implantation was 65.6% (126/192 patients). Most patients had 50-90% seizure reduction (60.9%) and nine patients became seizure-free. There were no serious complications associated with VNS implantation. The rate of a ≥ 50% seizure reduction response was significantly higher in patients with no history of neurosurgery. The presence of focal without generalized seizures and focal discharges on interictal EEG was associated with better response. Overall, etiological predictors of a better VNS response profile were tumors while a worse response to VNS was related to the presence of vascular malformations and Lennox-Gastaut Syndrome. Discussion: We observed an association between a better response to VNS therapy no history of neurosurgery, focal interictal epileptiform activity, and focal seizure pattern. Additionally, it is important to highlight that age was not a determinant factor of the response, as children and adults had similar response rates. Thus, VNS therapy should be considered in both adults and children with DRE.

RESUMO

Although the boll weevil (BW), Anthonomus grandis grandis (Coleoptera: Curculionidae) has been attributed to the significant losses caused to cotton yield in the Americas, the categorization as a quarentenary pest in places where it is still not occurring has increased its relevance worldwide. In areas where it is widespread, pest suppression relies on many broad-spectrum insecticide applications. However, other control tactics are sought. Considering that early-flowering cultivars escape from boll weevil infestation, we investigated if three different planting dates (November, December, and January) could alter the plant life cycle, allowing the plants to escape from boll weevil infestation. Field trials were run in two seasons (2014/2015 and 2017/2018), and variables (days required to reach each flowering stage, fruiting plant structures-undamaged and damaged by the BW, and totals-number of boll weevils on plants and that had emerged from fallen structures on the ground) were assessed over 29 and 33 weeks, respectively. Based on the number of days required to initiate and terminate the flowering stage, the time to reach the economic threshold (ET), the number of undamaged, damaged, and the total reproductive structures, we concluded that planting dates in December for the Central Cerrado of Brazil should be preferred over the other two tested dates. Cultivations run at this planting date, anticipating the flowering period initiation and termination, reduced infested flowering structures, and delayed the decision making to control the pest, when compared to the other two planting dates.

RESUMO

Common marmosets (Callithrix jacchus) are widely distributed in Northeast Brazil and often inhabit urban and peri-urban forest areas close to human settlements. Given its wide territorial distribution, its proximity to human populations, and its exposure to environmental degradations originating from urbanization, common marmosets have a high potential for environmental biomonitoring. The concentrations of iron (Fe) and chromium (Cr) were quantified in the liver, hair, and bone of 22 free-ranging common marmosets' bodies from nine cities from Pernambuco State, Brazil, using inductively coupled plasma optical emission spectrometry (ICP OES). The liver showed the highest concentrations of Fe and Cr (3773.2 ± 3715.8 mg/kg and 19.4 ± 41.6 mg/kg, respectively); the lowest concentration of Fe was detected in the bone (111.6 ± 97.6 mg/kg) and of Cr in the hair (3.3 ± 1.5 mg/kg). There was a moderate positive correlation between Fe and Cr in the liver (r = 0.64) and a high negative correlation for Cr between bone and hair (r = -0.65). This study demonstrated the bioaccumulation of Fe and Cr in hair, liver, and bone in common marmosets. The highest average concentration of Fe and Cr occurred in animals from Recife, Jaboatão dos Guararapes, and Paulista, respectively, the 1st, the 2nd, and the 5th most populated cities in the state of Pernambuco. The presence of high concentrations of metals in animals from Recife and nearby cities can indicate alarming levels of environmental pollution in these locations.

RESUMO

OBJECTIVE: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016. METHODS: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy. RESULTS: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others. CONCLUSION: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.

RESUMO

Urinary tract infections (UTIs) are common human infections that compromise women's health around the world, even though they can affect men and women of all ages. Bacterial species are the primary causative agents of UTIs, while Staphylococcus saprophyticus, a gram-positive bacterium, is especially important for uncomplicated infections in young women. Despite the number of antigenic proteins identified in Staphylococcus aureus and other bacteria of the genus, there is no immunoproteomic study in S. saprophyticus. In this context, since pathogenic microorganisms secrete important proteins that interact with hosts during infection, the present work aims to identify the exoantigens from S. saprophyticus ATCC 15305 by immunoproteomic and immunoinformatic approaches. We identified 32 antigens on the exoproteome of S. saprophyticus ATCC 15305 by immunoinformatic tools. By using 2D-IB immunoproteomic analysis, it was possible to identify 3 antigenic proteins: transglycosylase IsaA, enolase and the secretory antigen Q49ZL8. In addition, 5 antigenic proteins were detected by immunoprecipitation (IP) approach, where the most abundant were bifunctional autolysin and transglycosylase IsaA proteins. The transglycosylase IsaA was the only protein detected by all the tools approaches used in this study. In this work it was possible to describe a total of 36 S. saprophyticus exoantigens. Immunoinformatic analysis allowed the identification of 5 exclusive linear B cell epitopes from S. saprophyticus and 5 epitopes presenting homology with other bacteria that cause UTIs. This work describes, for the first time, the profile of exoantigens secreted by S. saprophyticus and can contribute to the identification of new diagnostic targets of UTIs, as well as to develop vaccines and immunotherapies against bacterial urinary infections.

RESUMO

BACKGROUND: The COVID-19 pandemic put healthcare professionals, including residents (postgraduate trainees of health professions), under intense physical and psychological stress, hence at risk for mental disorders. We evaluated the prevalence of mental disorders among healthcare residents during the pandemic. METHODS: From July to September 2020, residents in medicine and other healthcare specialties in Brazil were recruited. The participants completed electronic forms with validated questionnaires (DASS-21, PHQ-9, BRCS) to screen for depression, anxiety, and stress, and to evaluate resilience. Data on potential predisposing factors for mental disorders were also collected. Descriptive statistics, chi-squared, students t, correlation and logistic regression models were applied. The study received ethical approval, and all participants provided informed consent. RESULTS: We included 1313 participants (51.3% medical; 48.7% nonmedical) from 135 Brazilian hospitals; mean (SD) age: 27.8 (4.4) years; 78.2% females; 59.3% white race. Of all participants, 51.3%, 53.4% and 52.6% presented symptoms consistent with depression, anxiety, and stress, respectively; 61.9% showed low resilience. Nonmedical residents exhibited higher anxiety compared to medical residents (DASS-21 anxiety score, mean difference: 2.26; 95% CI: 1.15-3.37; p < 0.001). In multivariate analyses, having any pre-existent, nonpsychiatric chronic disease was associated with higher prevalence of symptoms indicative of depression (odds ratio, OR: 2.05; 95% CI: 1.47-2.85, on DASS-21 | OR: 2.26; 95% CI: 1.59-3.20, on PHQ-9), anxiety (OR: 2.07; 95% CI: 1.51-2.83, on DASS-21), and stress (OR: 1.53; 95% CI: 1.12-2.09, on DASS-21); other predisposing factors were identified; by contrast, high resilience (BRCS score) was protective against symptoms of depression (OR 0.82; 95% CI: 0.79-0.85, on DASS-21 | OR 0.85; 95% CI: 0.82-0.88, on PHQ-9), anxiety (OR 0.90; 95% CI: 0.87-0.93, on DASS-21), and stress (OR 0.88; 95% CI: 0.85-0.91, on DASS-21); p < 0.05 for all outcomes. CONCLUSIONS: We found a high prevalence of mental disorder symptoms among healthcare residents during COVID-19 pandemic in Brazil. Nonmedical residents exhibited higher levels of anxiety than medical ones. Some predisposing factors for depression, anxiety and stress among residents were identified.

RESUMO

The global burden of disease estimated that approximately 7.1 million deaths worldwide were related to air pollution in 2016. However, only a limited number of small- and middle-sized cities have air quality monitoring networks. To date, air quality in terms of particulate matter is still mainly focused on mass concentration, with limited compositional monitoring even in mega cities, despite evidence indicating differential toxicity of particulate matter. As this evidence is far from conclusive, we conducted PM2.5 bioaccessibility studies of potentially harmful elements in a medium-sized city, Londrina, Brazil. The data was interpreted in terms of source apportionment, the health risk evaluation and the bioaccessibility of inorganic contents in an artificial lysosomal fluid. The daily average concentration of PM2.5 was below the WHO guideline, however, the chemical health assessment indicated a considerable health risk. The in vitro evaluation showed different potential mobility when compared to previous studies in large-sized cities, those with 1 million inhabitants or more (Curitiba and Manaus). The new WHO guideline for PM2.5 mass concentration puts additional pressure on cities where air pollution monitoring is limited and/or neglected, because decision making is mainly revenue-driven and not socioeconomic-driven. Given the further emerging evidence that PM chemical composition is as, or even more, important than mass concentration levels, the research reported in the paper could pave the way for the necessary inter- and intra-city collaborations that are needed to address this global health challenge.

RESUMO

BACKGROUND: Since the beginning of the COVID-19 pandemic, health professionals have been working under extreme conditions, increasing the risk of physical and mental illness. We evaluated the prevalence of burnout and its associated factors among postgraduate student residents in health professions during the global health crisis. METHODS: Healthcare residents were recruited from all across Brazil between July and September 2020 through digital forms containing instruments for assessing burnout (Oldenburg Burnout Inventory (OLBI)), resilience (brief resilient coping scale (BRCS)) and anxiety, stress and depression (depression, anxiety and stress scale (DASS-21) and Patient Health Questionnaire (PHQ-9)). Additionally, the relationships between burnout and chronic diseases, autonomy and educational adequacy in the residency programme, personal protective equipment (PPE), workload and care for patients with COVID-19 were evaluated. The chi-square test, Student's t test, Pearson's correlation test and logistic regression were performed. RESULTS: A total of 1,313 participants were included: mean (standard deviation) age, 27.8 (4.4) years; female gender, 78.1%; white race, 59.3%; and physicians, 51.3%. The overall prevalence of burnout was 33.4%. The odds (odds ratio [95% confidence interval]) of burnout were higher in the presence of pre-existing diseases (1.76 [1.26-2.47]) and weekly work > 60 h (1.36 [1.03-1.79]) and were lower in the presence of high resilience (0.84 [0.81-0.88]), autonomy (0.87 [0.81-0.93]), and educational structure (0.77 [0.73-0.82]), adequate availability of PPE (0.72 [0.63-0.83]) and non-white race (0.63 [0.47-0.83]). Burnout was correlated with anxiety (r = 0.47; p < 0.05), stress (r: 0.58; p < 0.05) and depression (r: 0.65; p < 0.05). CONCLUSIONS: We observed a high prevalence of burnout among residents during the COVID-19 pandemic. Individual characteristics and conditions related to the work environment were associated with a higher or lower occurrence of the syndrome.

RESUMO

BACKGROUND: Immune tolerance induction (ITI) is the treatment of choice for eradication of anti-factor VIII (FVIII) neutralizing alloantibodies (inhibitors) in people with inherited hemophilia A and high-responding inhibitor (PwHA-HRi). The association between ITI outcome and time elapsed between inhibitor detection and start of ITI (∆tinhi-ITI ) is debatable. OBJECTIVE: The aim of this study was to evaluate this association among a large cohort of severe PwHA-HRi. METHODS: Severe (factor VIII activity level <1%) PwHA-HRi on ITI (n = 142) were enrolled in 15 hemophilia treatment centers. PwHA-HRi were treated according to the Brazilian ITI Protocol. ITI outcomes were defined as success (i.e., recovered responsiveness to exogenous FVIII) and failure (i.e., no responsiveness to exogenous FVIII and requirement of bypassing agents to control bleeding). RESULTS: Median ages at inhibitor detection and at ITI start were 3.2 years (interquartile range [IQR], 1.6-8.1) and 6.9 years [IQR, 2.6-20.1), respectively. PwHA-HRi were stratified according to ∆tinhi-ITI quartiles: first (0.0-0.6 year), second (>0.6-1.7 year), third (>1.7-9.2 years), and fourth quartile (>9.2-24.5 years). The overall success rate was 65.5% (93/142), with no difference among first, second, third, and fourth quartiles (62.9%, 69.4%, 58.3%, and 71.4%, respectively) even after adjusting the analyses for potential confounders. CONCLUSION: In conclusion, delayed ITI start is not associated with failure of ITI in PwHA-HRi. Therefore, ITI should be offered for these patients, regardless of the time elapsed between the detection of inhibitor and the ITI start.

RESUMO

Despite the intramuscular route being the most used vaccination strategy against SARS-CoV-2, the intradermal route has been studied around the globe as a strong candidate for immunization against SARS-CoV-2. Adjuvants have shown to be essential vaccine components that are capable of driving robust immune responses and increasing the vaccination efficacy. In this work, our group aimed to develop a vaccination strategy for SARS-CoV-2 using a trimeric spike protein, by testing the best route with formulations containing the adjuvants AddaS03, CpG, MPL, Alum, or a combination of two of them. Our results showed that formulations that were made with AddaS03 or CpG alone or AddaS03 combined with CpG were able to induce high levels of IgG, IgG1, and IgG2a; high titers of neutralizing antibodies against SARS-CoV-2 original strain; and also induced high hypersensitivity during the challenge with Spike protein and a high level of IFN-γ producing CD4+ T-cells in mice. Altogether, those data indicate that AddaS03, CpG, or both combined may be used as adjuvants in vaccines for COVID-19.

RESUMO

This study aimed to evaluate Toxoplasma gondii infection in pregnant goats. The goats were divided into two groups: group one (G1) comprised of 31 pregnant goats naturally infected with T. gondii, and group two (G2) comprised of seven uninfected pregnant goats from a flock with a history of abortion due to toxoplasmosis. Serological investigation, ultrasonography, and clinical testing were performed on all goats during gestation. Serum samples from goats and their offspring (precolostral) were collected to evaluate the vertical transmission of T. gondii. Samples from placentas and aborted fetuses were also collected for molecular and histopathological analysis. Results showed that in G1, estrus recurrence occurred in 22.6% (7/31) of the goats, embryonic death in 3.3% (1/31), and abortion in 19.4% (6/31). An increase in anti-T. gondii antibodies was observed in G1 goats at day 150 of pregnancy. T. gondii DNA was detected in 42.8% (3/7) of aborted fetuses and was associated with histopathological lesions caused by this parasite. Moreover, toxoplasmosis in field conditions caused by genotype ToxoDB #1 in pregnant goats resulted in severe reproductive loss in the flock.

RESUMO

ABSTRACT The COVID-19 pandemic has led to a great number of hospitalizations. A considerable number of cases progress to the severe form of the infection and death. Prone positioning is a therapeutic strategy with strong evidence of reduced mortality in patients with acute respiratory distress syndrome (ARDS). This study aims to assess if the prone positioning strategy is used by health professionals in hospitals to treat patients with COVID-19 on invasive mechanical ventilation and the professionals' perception of its effect on the mortality rate. This is a cross-sectional study, with a convenience sample composed of health professionals of both sexes working in hospitals throughout Brazil. Participants answered an online questionnaire composed of 16 questions using Google Forms, from July 2020 to September 2020. A total of 455 questionnaires were answered. Prone positioning is routinely performed in hospitals where 386 (95%) of the responding professionals work. Among them, 374 (96.9%) consider that the prone position strategy reduces hypoxemia and 289 (74.9%) consider that it reduces mortality in patients with COVID-19 and ARDS on invasive mechanical ventilation. Finally, most health professionals working in Brazilian hospitals perform and believe that prone positioning reduces hypoxemia and mortality in patients with COVID-19 on invasive mechanical ventilation.


RESUMO A pandemia de covid-19 gerou um grande número de internações hospitalares e uma quantidade considerável de casos evolui para a forma grave da doença e óbito. A manobra de posição prona é uma estratégia terapêutica com forte evidência de redução da mortalidade em pacientes com síndrome do desconforto respiratório agudo (SDRA). Este estudo teve como objetivo verificar se a manobra de decúbito ventral é realizada como estratégia de tratamento de pacientes com covid-19 em ventilação mecânica invasiva por profissionais de saúde que atuam em ambiente hospitalar e a percepção sobre seu impacto na mortalidade. Trata-se de um estudo transversal, com amostra de conveniência composta por profissionais de saúde que atuam em hospitais de todo o Brasil, de ambos os sexos. Os participantes responderam a um questionário online, composto por 16 questões, elaborado no Google Forms, de julho a setembro de 2020. Quatrocentos e cinquenta e cinco questionários foram respondidos. A manobra da posição prona é realizada rotineiramente em hospitais onde atuam 386 profissionais (95%). Desses, 374 (96,9%) têm a percepção de que a manobra de decúbito ventral reduz a hipoxemia e 289 (74,9%) percebe que ela reduz a mortalidade de pacientes com covid-19 e SDRA em ventilação mecânica invasiva. Em conclusão, a maioria dos profissionais de saúde que atuam em hospitais brasileiros realiza e acredita que a manobra de decúbito ventral reduz a hipoxemia e a mortalidade em pacientes com covid-19 em ventilação mecânica invasiva.


RESUMEN La pandemia del Covid-19 ha generado un incremento de las hospitalizaciones y un gran número de casos de esta enfermedad ha evolucionado a su forma grave y la muerte. El manejo de la posición de decúbito prono es una estrategia terapéutica con sólida evidencia de reducción de la mortalidad en pacientes con síndrome de dificultad respiratoria aguda (SDRA). Este estudio tuvo como objetivo comprobar si la posición de decúbito prono es realizada por los profesionales de la salud que trabajan en un hospital como estrategia para el tratamiento de pacientes con el Covid-19 en ventilación mecánica invasiva y la percepción de estos profesionales sobre el impacto de tal práctica en la mortalidad. Se trata de un estudio transversal, con una muestra de conveniencia compuesta por profesionales de la salud que actúan en hospitales de todo Brasil, de ambos sexos. Los participantes respondieron un cuestionario en línea, con 16 preguntas en Google Forms, en el periodo de julio a septiembre de 2020. Se respondieron 455 cuestionarios. El manejo de la posición de decúbito prono se realiza de forma rutinaria en los hospitales donde trabajan 386 profesionales (95%). De estos, 374 (96,9%) tienen la percepción de que el manejo de la posición de decúbito prono reduce la hipoxemia y 289 (74,9%) perciben que esta práctica reduce la mortalidad de los pacientes con Covid-19 y SDRA en ventilación mecánica invasiva. Se concluye que la mayoría de los profesionales de la salud que actúan en los hospitales brasileños realizan y creen que la posición de decúbito prono reduce la hipoxemia y la mortalidad en pacientes con Covid-19 en ventilación mecánica invasiva.
