Er,Cr:YSGG and 980nm diode lasers influence dentin surface volume after cariogenic challenge: in vitro study.

This study aimed to evaluate the influence of the Er,Cr:YSGG irradiation and 980-nm diode lasers on the surface roughness (SR) and volume loss (VL) of dentin subjected to cariogenic challenge. Subsequently, 130 specimens of bovine dentin were divided into the following 13 groups: NT: no treatment; FG: fluoride gel; FV: fluoride varnish; Di: 980-nm diode; Di + FG; Di + FV; FG + D; FV + Di; Er: Er,Cr:YSGG; Er + FG; Er + FV; FG + Er and FV + Er. Er,Cr:YSGG laser parameters were as follows: 0.25 W; 5.0 Hz; 4.46 J/cm2 without water and 55% air. Furthermore, the 980-nm diode laser parameters were 2.0 W; 2.0 Hz; 21.41 J/cm2. The samples from each group were subjected to pH cycling. A confocal laser scanning microscope was used to evaluate SR and VL. Difference between the volume of the reference and treated areas + DES/RE was used to determine SR and VL. The mean values of the different groups were subjected to analysis of variance and Tukey's post-hoc test. The VL values were analyzed using the Kruskal-Wallis and Dunn post-hoc test (p < 0.05). The SR of the reference area did not show a statistically significant 1807-3107-bor-38-e025treatment and cariogenic challenge (p > 0.05). Moreover, VL in the FV + Di and FV + Er groups showed a statistically significant difference compared with areas submitted to different types of treatment and cariogenic challenge (p > 0.05). Er,Cr:YSGG and 980-nm diode lasers associated with fluoride varnishes decreased dentin VL in bovine teeth submitted to cariogenic challenge.

Women with disabilities and their motherhood: scoping review. / Mulheres com deficiência e a experiência da maternidade: revisão de escopo.

This review aims to disclose the gaps and needs for acknowledging the rights to experience motherhood of women with disabilities. To do so, we map how much is known about these women's experience with motherhood, shedding light on their sexual and reproductive rights. The present work followed the scoping review by the Joanna Briggs Institute (JBI). This research is structured by elaborating the question, identifying the relevant studies, selecting the studies, extracting the data, sorting, summarizing, and creating reports based on the results. Results: we found 1050 articles, of which 53 were selected for the analysis. considering the different themes, we generated three axes: (1) infantilization, dehumanization, and discredit in the experience of motherhood; (2) obstetric ableism - an expression of violence in obstetrics; (3) reproductive justice - politicize motherhood and care. The study showed the urgent need to regard women with disabilities as people having the right to make sexual and reproductive health choices. Health professionals need permanent education to acknowledge and guarantee such a need as interweaving relationships to reach decision-making and autonomy.

Analysis of ankle muscle activity: A study on static balance with eyes closed and high-heeled shoes.

BACKGROUND: Changes in sensory afferent interfere with the control of postural stability by the central nervous system. Wearing high-heeled shoes is an example of an external disturbance that changes sensory inputs and results in several postural adjustments to control stability. Thus, our purpose is to investigate the influence of high-heeled shoes and visual absence on maintenance of static balance and on ankle muscle activity among young women. Our hypothesis is that the combination of high-heeled shoes with visual absence lead to an increase of postural sway and of levels of activation of the stabilizing ankle muscles. METHODS: Nine volunteers remained in an unrestrained erect posture on a force platform for collecting of stabilometric and electromyographic parameters in four bipodal conditions: barefoot with open eyes, barefoot with closed eyes, with high heels and open eyes and with high heels and closed eyes. RESULTS: When comparing the experimental condition open and closed eyes with high heels, there were significant differences for all stabilometric variables, except for the confidence ellipse area. Statistical differences were found for the medial gastrocnemius muscle in all comparison pairs with high heels. CONCLUSION: The wearing high-heeled shoes showed to be the most influencing disturbance on static balance. Our findings suggest ankle muscle activity is adapted according to changes of the center of pressure sway and the wearing of high heels changes the muscle activation and postural sway.

Cultivable Fungi from Amazon River Dolphins Engaged in Wildlife Ecotourism in the Anavilhanas National Park, Brazil.

Amazon River dolphins are an important flagship species in the Anavilhanas National Park, Brazil, where they interact with visitors. This study aimed to quantify and identify fungi isolated from dolphin skin and oral samples and their surrounding environment in this unique ecosystem. Samples were collected from three dolphins and water samples from Flutuante dos Botos and the Novo Airão city harbor. Fungi were isolated using culture media and identified through micromorphology assays and ITS region sequencing. Oral swab samples resulted in culture of Trichosporon montevideense and Exophiala dermatitidis. Skin samples from one dolphin revealed Toxicocladosporium irritans and Diaporthe lithocarpus. Water samples exhibited higher fungal counts and diversity, with Rhodotorula mucilaginosa, Exophiala dermatitidis, Penicillium citrinum, Fomitopsis meliae, and Nectria pseudotrichia identified at the collection site and Candida spencermartinsiae and Penicillium chermesinum at the city harbor. This study provides important insights into the fungal diversity associated with Amazon River dolphins and their environment, enhancing our understanding of the public health and ecological dynamics in the Anavilhanas National Park.

Dynamics of Carbon and Soil Enzyme Activities under Arabica Coffee Intercropped with Brachiaria decumbens in the Brazilian Cerrado.

The change in land use in the Brazilian Cerrado modifies the dynamics of soil organic matter (SOM) and, consequently, carbon (C) stocks and their fractions and soil enzyme activities. This study evaluated the effect of brachiaria (Brachiaria decumbens Stapf.) intercropped with Arabica coffee (Coffea arabica L.) on the stock and fractions of soil carbon and enzyme activities. The experiment was arranged in a completely randomized block design with three replications and treatments in a factorial design. The first factor consisted of coffee with or without intercropped brachiaria, the second of Arabica coffee cultivars ('I.P.R.103' and 'I.P.R.99') and the third factor of the point of soil sampling (under the canopy (UC) and in inter-rows (I)). Soil was sampled in layers of 0-10, 10-20, 20-30, 30-40, 40-60 and 60-80 cm. Soil from the 0-10 cm layer was also used to analyze enzymatic activity. Significant effects of coffee intercropped with brachiaria were confirmed for particulate organic carbon (POC), with highest contents in the 0-10 and 20-30 cm layers (9.62 and 6.48 g kg-1, respectively), and for soil enzymes (280.83 and 180.3 µg p-nitrophenol g-1 for arylsulfatase and ß-glucosidase, respectively).

Toxicity Assessment of New Ag-ZnO/AgO Nanocomposites: An In Vitro and In Vivo Approach.

Zinc oxide nanoparticles (ZnO NPs) are metal oxide nanomaterials, which are important for several applications: antibacterial, anthelmintic, antiprotozoal and antitumoral, among others. These applications are mainly related to the ability to spontaneously produce and induce the production of reactive oxygen species that are important components for the destruction of pathogens and tumor cells. While trying to potentiate ZnO NPs, studies have associated these NPs with silver oxide (AgO) or silver (Ag) NPs. It has already been reported that this combination (Ag-ZnO/AgO NPs) is able to enhance the microbicidal potential. Although possessing much potential for several purposes, it is important to evaluate whether this association also poses the risk of toxicity to cells and experimental models. Therefore, this work aimed to evaluate the toxicity of various Ag-ZnO/AgO NP nanocomposites, in vitro and in vivo. Accordingly, ZnO nanocrystals and nanocomposites with various concentrations of AgO (ZnO:5Ag, ZnO:9Ag or ZnO:11Ag) were used in different cytotoxicity models: Galleria mellonella (G. mellonella), cell lines (VERO and RAW 264.7) and C57BL/6 mice. In the G. mellonella model, four concentrations were used in a single dose, with subsequent evaluation of mortality. In the case of cells, serial concentrations starting at 125 µg/mL were used, with subsequent cytotoxicity assessment. Based on the safe doses obtained in G. mellonella and cell models, the best doses were used in mice, with subsequent evaluations of weight, biochemistry as also renal and liver histopathology. It was observed that the toxicity, although low, of the nanocomposites was dependent upon the concentration of AgO used in association with ZnO NPs, both in vitro and in vivo.

7.1',8.3'- and 7.3',8.5'-Connected Bicyclo[3.2.1]octanoids and Oxabicyclo[3.2.2]nonane-Type Neolignans from Ocotea aciphylla: Structures and Absolute Configurations.

The phytochemical investigation of the leaves and trunk bark of a specimen of Ocotea aciphylla collected in the southern portion of the Amazon forest led to the isolation of an oxabicyclo[3.2.2]nonane-type neolignan and 15 bicyclo[3.2.1]octanoid neolignans, 14 of which are unreported compounds (2-15), including one with an unusual oxidation pattern of the side chain at C-1' and two rare 7.1',8.3'-connected bicyclo[3.2.1]octanoid derivatives. Their structures and relative configurations were determined by extensive spectrometric analysis based on 1D- and 2D-NMR spectroscopy and HRESIMS data, while their absolute configurations were unambiguously assigned using electronic and vibrational circular dichroism data assisted by density functional theory calculations. Additionally, known sesquiterpenes, phenylpropanoids, and phytosterols were also isolated.

The Influence of IL-11 on Cardiac Fibrosis in Experimental Models: A Systematic Review.

Fibrosis is one of the main factors that impair the function of many organs. In the heart, fibrosis leads to contractile dysfunction and arrhythmias, which are important in the development of heart failure. Interleukin (IL)-11 is regulated in various heart diseases and has recently been reported to be an important cytokine in fibrosis in this organ. However, this topic has been little explored, and many questions persist. Thus, this systematic review aimed to report on possible IL-11 therapies evaluated in rodent model-induced cardiac fibrosis. Inclusion criteria were experimental in vivo studies that used different rodent models for cardiac fibrosis associated with IL-11 interventions, without year and language restrictions. The search in PubMed, Web of Science, and Embase databases was performed in October 2022. The risk of bias assessment of the studies was based on the guidelines of the SYRCLE tool, and data from the selected articles were also presented in a table as a narrative description. This review was based on eight studies in which five different interventions were used: recombinant human IL-11 (rhIL-11), anti-IL11 (X203), recombinant mouse IL-11 (rmIL-11), lentivirus (LV)-IL-11 + lutein, and anti-IL11RA (X209). Based on the included studies, the results were variable, with IL-11 overexpression inducing cardiac fibrosis, while inhibition protected against this process, preserving the function of this organ. Therefore, IL-11 stands out as a promising therapeutic target for cardiac fibrosis. However, further studies are needed to understand the mechanisms triggered by each treatment, as well as its safety and immunogenicity.

Effects of a lifestyle intervention on cardiovascular risk factors in systemic lupus erythematosus patients: The study "Living well with lupus".

OBJECTIVE: The aim of the present study was to investigate the effects of a lifestyle intervention on cardiometabolic risk factors in patients with systemic lupus erythematosus with a high cardiovascular risk profile. METHODS: This trial was conducted in Sao Paulo, Brazil between August 2020 and March 2023. The patients were randomly assigned to lifestyle intervention or control. The intervention was a 6-month multifaced program focused on behavioral changes through personalized recommendations for increasing physical activity (structured and non-structured) and improving eating aspects. Cardiometabolic risk score (primary outcome), anthropometry and visceral fat, aerobic capacity, blood pressure, inflammatory and oxidative stress markers, and blood flow and endothelial function were assessed before and after the intervention. RESULTS: A total of 80 patients were randomized. Twelve and 6 patients dropped out due to personal reasons in the intervention and control groups, respectively. Average adherence rate for the intervention was 56.9%. Intention-to-treat analysis showed no significant difference between groups in the cardiometabolic risk score (intervention group - Pre: 1.7 ± 3.6; Post: -1.6 ± 4.0; control group - Pre: -1.9 ± 3.6; Post: -2.0 ± 3.8; estimated mean difference between groups at post: -0.4; 95% confidence intervals: -2.7; 1.9; p = 0.96). This finding was confirmed by exploratory, per-protocol analysis. No significant differences were observed between adherents vs. non-adherent participants. Secondary outcomes did not change between groups. CONCLUSION: This 6-month, individualized, lifestyle intervention did not improve cardiovascular risk factors in SLE patients with a high cardiovascular risk profile.

A single session of aerobic exercise reduces systolic blood pressure at rest and in response to stress in women with rheumatoid arthritis and hypertension.

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease characterized by increased risk of cardiovascular disease and hypertension (HT). A single session of aerobic exercise may reduce blood pressure (BP) in different clinical groups; however, little is known about the acute effects of exercise on BP in RA patients. This is a randomized controlled crossover study that assessed the effects of a single session of aerobic exercise on resting BP, on BP responses to stressful stimuli, and on 24-h BP in women with RA and HT. Twenty women with RA and HT (53 ± 10 years) undertook sessions of 30-min treadmill exercise (50% VO2max) or control (no exercise) in a crossover fashion. Before and after the sessions, BP was measured at rest, and in response to the Stroop-Color Word Test (SCWT), the Cold Pressor Test (CPT), and an isometric handgrip test. After the sessions, participants were also fitted with an ambulatory BP monitor for the assessment of 24-h BP. A single session of exercise reduced resting systolic BP (SBP) (-5 ± 9 mmHg; p < 0.05), and reduced SBP response to the SCWT (-7 ± 14 mmHg; p < 0.05), and to the CPT (-5 ± 11 mmHg; p < 0.05). Exercise did not reduce resting diastolic BP (DBP), BP responses to the isometric handgrip test or 24-h BP. In conclusion, a single session of aerobic exercise reduced SBP at rest and in response to stressful stimuli in hypertensive women with RA. These results support the use of exercise as a strategy for controlling HT and, hence, reducing cardiovascular risk in women with RA.Clinical Trial Registration: This study registered at the Brazilian Clinical Trials ( https://ensaiosclinicos.gov.br/rg/RBR-867k9g ) at 12/13/2019.

Viability and oxidative stress of dental pulp cells after indirect application of chemomechanical agents: An in vitro study.

AIM: This study evaluated the transdentinal cytotoxic effects of enzymatic agents (EA) for chemomechanical carious tissue removal on human dental pulp cells. METHODOLOGY: The groups were based on the performed dentine treatments (n = 8): G1: Positive Control (PC - no treatment); G2: Negative Control (NC - 35% H2 O2 for 2 min); G3: Brix 3000™ (BX) for 30 s; G4: BX for 2 min; G5: Papacarie Duo™ (PD) for 30 s; G6: PD for 2 min. The cells were evaluated for viability (VB; MTT assay) and production of reactive oxygen species (ROS; DCFH-DA assay) and nitric oxide (NO; Griess reagent). A scanning electron microscope provided morphological chemical analyses and energy-dispersive X-ray spectroscopy. The data were submitted to the one-way anova statistical test complemented by Tukey (p < .05). RESULTS: Cell viability decreased by 21.1% and 58.4% in G5 and G6, respectively. ROS production in G3 and G4 maintained basal levels but increased by 171.2% and 75.1% in G5 and G6, respectively. CONCLUSIONS: The Brix3000™ enzymatic agent did not cause indirect cytotoxic effects on pulp cells, regardless of the application time. Conversely, Papacarie Duo™ reduced viability and increased ROS production by pulp cells.

Performance of severity indices for admission and mortality of trauma patients in the intensive care unit: a retrospective cohort study.

BACKGROUND: Little is known about the performance of severity indices for indicating intensive care and predicting mortality in the Intensive Care Unit (ICU) of trauma patients. This study aimed to compare the performance of severity indices to predict trauma patients' ICU admission and mortality. METHODS: A retrospective cohort study which analyzed the electronic medical records of trauma patients aged ≥ 18 years, treated at a hospital in Brazil, between 2014 and 2017. Physiological [Revised Trauma Score (RTS), New Trauma Score (NTS) and modified Rapid Emergency Medicine Score (mREMS)], anatomical [Injury Severity Score (ISS) and New Injury Severity Score (NISS)] and mixed indices [Trauma and Injury Severity Score (TRISS), New Trauma and Injury Severity Score (NTRISS), Base-deficit Injury Severity Score (BISS) and Base-deficit and New Injury Severity Score (BNISS)] were compared in analyzing the outcomes (ICU admission and mortality) using the Area Under the Receiver Operating Characteristics Curves (AUC-ROC). RESULTS: From the 747 trauma patients analyzed (52.5% female; mean age 51.5 years; 36.1% falls), 106 (14.2%) were admitted to the ICU and 6 (0.8%) died in the unit. The ISS (AUC 0.919) and NISS (AUC 0.916) had better predictive capacity for ICU admission of trauma patients. The NISS (AUC 0.949), TRISS (AUC 0.909), NTRISS (AUC 0.967), BISS (AUC 0.902) and BNISS (AUC 0.976) showed excellent performance in predicting ICU mortality. CONCLUSIONS: Anatomical indices showed excellent predictive ability for admission of trauma patients to the ICU. The NISS and the mixed indices had the best performances regarding mortality in the ICU.

Medicinal plant Miconia albicans synergizes with ampicillin and ciprofloxacin against multi-drug resistant Acinetobacter baumannii and Staphylococcus aureus.

BACKGROUND: Given the rising occurrence of antibiotic resistance due to the existence and ongoing development of resistant bacteria and phenotypes, the identification of new treatments and sources of antimicrobial agents is of utmost urgency. An important strategy for tackling bacterial resistance involves the utilization of drug combinations, and natural products derived from plants hold significant potential as a rich source of bioactive compounds that can act as effective adjuvants. This study, therefore, aimed to assess the antibacterial potential and the chemical composition of Miconia albicans, a Brazilian medicinal plant used to treat various diseases. METHODS: Ethanolic extracts from leaves and stems of M. albicans were obtained and subsequently partitioned to give the corresponding hexane, chloroform, ethyl acetate, and hydromethanolic phases. All extracts and phases had their chemical constitution investigated by HPLC-DAD-MS/MS and GC-MS and were assessed for their antibiofilm and antimicrobial efficacy against Staphylococcus aureus. Furthermore, their individual effects and synergistic potential in combination with antibiotics were examined against clinical strains of both S. aureus and Acinetobacter baumannii. In addition, 10 isolated compounds were obtained from the leaves phases and used for confirmation of the chemical profiles and for antibacterial assays. RESULTS: Based on the chemical profile analysis, 32 compounds were successfully or tentatively identified, including gallic and ellagic acid derivatives, flavonol glycosides, triterpenes and pheophorbides. Extracts and phases obtained from the medicinal plant M. albicans demonstrated synergistic effects when combined with the commercial antibiotics ampicillin and ciprofloxacin, against multi-drug resistant bacteria S. aureus and A. baumannii, restoring their antibacterial efficacy. Extracts and phases also exhibited antibiofilm property against S. aureus. Three key compounds commonly found in the samples, namely gallic acid, quercitrin, and corosolic acid, did not exhibit significant antibacterial activity when assessed individually or in combination with antibiotics against clinical bacterial strains. CONCLUSIONS: Our findings reveal that M. albicans exhibits remarkable adjuvant potential for enhancing the effectiveness of antimicrobial drugs against resistant bacteria.

Association of physical performance and sarcopenia with use of health services in elderly people living in rural riverside areas in the Amazon: a cross-sectional study.

INTRODUCTION: Access is considered one of the necessary conditions for achieving effectiveness and quality in health services. However, it represents a complex construct, with several interpretations, and can be understood as the ease or degree of difficulty with which people obtain effective and timely care. Barriers to access can be related to individual characteristics and those of health systems and services. Regarding elderly people living in rural riverine localities, these limitations are exacerbated due to the territorial dispersion of households and the difficulty of obtaining the necessary care near their homes. The aim of this study was to describe and test the association of sarcopenia and physical performance with primary healthcare attributes and the use of health services by elderly people living in rural riverside areas in the Amazon, Brazil. METHODS: This cross-sectional observational study was carried out in households with individuals aged 60 years or older living in nine communities located on the left bank of the Negro River, in the rural riverside area of the municipality of Manaus, Amazonas, Brazil. The study evaluated socioeconomic and demographic conditions, health services utilization and the primary care attributes related to the use of and access to services, assessed by components of the Primary Care Assessment Tool instrument (PCATool-Brazil), a reduced version validated for Brazilian adult users. Physical performance was assessed using the Short Physical Performance Battery scale, and handgrip strength was also assessed, according to a dynamometer. The Sarcopenia Formulary (SARC-F) and calf circumference (CC) were used to assess sarcopenia (SARC-CalF). The association of sarcopenia and physical performance with the study outcomes was evaluated using hierarchical logistic regression for health services utilization (having had a medical consultation in the last year), and hierarchical linear regression for the continuous outcomes of the PCATool-Brazil (total score and each of the domains). The sociodemographic variables were inserted in model 1 and the clinical variables in model 2. Variables with p<0.20 were kept in the models. RESULTS: A total of 98 elderly people (55.1% men; mean age 70±7.4 years) were included in the study. Low physical performance and suggestive signs of sarcopenia were observed in 52.5% and 28.9% of the study participants, respectively. Elderly with better physical performance reported more health services utilization (odds ratio (OR)=1.37; 95% confidence interval (CI)=1.03-1.81) and higher scores in the affiliation (β=1.67; 95%CI=0.37-2.98), utilization (β=1.19; 95%CI=0.06-2.33) and longitudinality (β=0.99; 95%CI=0.09-1.90) domains of the PCATool-Brazil. CONCLUSION: The study findings showed high prevalence of impairment in physical performance and suggestive signs of sarcopenia in elderly people living in the studied rural riverside localities. Better physical performance was associated with use of health services in the previous year and with better evaluation of some primary care attributes.

Assessing the impact of prophylactic anidulafungin during remission induction of acute myeloid leukemia - A propensity-score matching analysis.

INTRODUCTION: Invasive fungal infection (IFI) accounts for substantial morbidity during the treatment of acute myeloid leukemia (AML) in adults. Antifungal prophylaxis (AP) is needed during intensive chemotherapy, and posaconazole is not widely available. In this study, we aimed to examine the impact of prophylactic anidulafungin during intensive AML remission induction. METHODS: This is a retrospective cohort encompassing newly diagnosed AML adult patients. All subjects received intensive chemotherapy and were divided into three groups: patients who did not receive any AP and patients who received fluconazole (150-400 mg/day) or anidulafungin (100 mg/day). RESULTS: During AML induction, 82 patients did not receive AP, 108 and 14 patients received anidulafungin and fluconazole, respectively. IFI incidence was 27%, classified as possible, probable, and proven in 65, 2 and 33%, respectively. Multivariable analysis showed that lower neutrophil counts are associated with IFI (OR = 2.8), whereas age, genetic classification, and lymphocyte counts were not. To examine the impact of anidulafungin in comparison with 'no AP', a propensity score matching analysis was performed. Use of anidulafungin was not related to less IFI during induction, while neutrophil counts remained significant. Patients under prophylactic anidulafungin received less amphotericin B (p < 0.001) but not voriconazole (p = 0.49). DISCUSSION: To our knowledge, this is the first study addressing the role of anidulafungin during AML induction. Here, the incidence of mold infections did not decrease with AP, suggesting that in a setting with a high incidence of IFI, broad spectrum AP might be more suitable.

Dengue Fever Surveillance in Mato Grosso do Sul: Insights from Genomic Analysis and Implications for Public Health Strategies.

Since its discovery in early 1916, dengue fever, a common vector-borne illness in Brazil, has resulted in extensive urban outbreaks and poses a serious threat to the public's health. Understanding the dynamics of Dengue Virus (DENV) serotypes circulating in different regions of Brazil is essential for implementing effective disease control and prevention measures. In response to this urgent need, we conducted an on-site training program in genomic surveillance in collaboration with the Central Laboratory of Health and the Secretary of Health of the Mato Grosso do Sul state. This initiative resulted in the generation of 177 DENV genome sequences collected between May 2021 and May 2022, a period during which over 11,391 dengue fever cases were reported in the state. Through this approach, we were able to identify the co-circulation of two different dengue serotypes (DENV1 and DENV2) as well as the existence of diverse viral lineages within each genotype, suggesting that multiple introduction events of different viral strains occurred in the region. By integrating epidemiological data, our findings unveiled temporal fluctuations in the relative abundance of different serotypes throughout various epidemic seasons, highlighting the complex and changing dynamics of DENV transmission throughout time. These findings demonstrate the value of ongoing surveillance activities in tracking viral transmission patterns, monitoring viral evolution, and informing public health actions.

Administrative professionals' quality of life in educational institutions: a systematic review protocol.

INTRODUCTION: Indicators of administrative professionals' quality of life (QoL) in educational institutions are essential for planning improvements in their daily lives. QoL is a recurring topic in academic research, particularly in the healthcare sector. Therefore, this study aims to evaluate the perceptions of administrative professionals in educational institutions regarding their QoL and the implications of remote and in-person work. Additionally, we aim to compare the QoL before, during and after the COVID-19 pandemic. METHODS AND ANALYSIS: Five electronic databases will be searched for this systematic review: CINAHL, LILACS, PubMed, Scopus and Web of Science. Original, peer-reviewed articles published in any language, without time limitations, will be included in this study. Two researchers will screen the articles and extract the data. The included articles will be evaluated for the quality of their evidence using Grading of Recommendations, Assessment, Development and Evaluations. The risk of bias will be assessed using the Critical Appraisal Skills Programme checklist and the Downs and Black scale. A third reviewer will resolve any discrepancies. ETHICS AND DISSEMINATION: The systematic review results will be published in a peer-reviewed journal and presented at a relevant conference. The data will not include individual patient data; therefore, ethical approval is not required. PROSPERO REGISTRATION NUMBER: CRD42022365862.
