Objectives: to develop, validate, and evaluate an educational video on the prevention and management of antineoplastic agent extravasation, aimed at nursing professionals., Methods: this methodological study was developed according to Falkembach's theoretical framework, which outlines five phases in the production of educational video materials: analysis and planning, modeling, implementation, evaluation, and distribution., Results: content validation demonstrated agreement above the minimum threshold stipulated. The overall Content Validity Index was 90.8%, and it was 94.2% among the content and technical evaluation judges, respectively. The target audience evaluated the video positively, highlighting the importance of the content, the clarity of the language used, and the understanding of the information pertinent to the topic., Conclusions: the video proved to be an appropriate strategy for instructing interventions on the prevention and management of extravasation, with the potential to improve educational practices among nursing professionals.

Pain represents one of the leading causes of suffering and disability worldwide. Currently available drugs cannot treat all types of pain and may have adverse effects. Hence, the use of pharmacological combinations is an alternative treatment strategy. Therefore, this study aimed to evaluate the combination of resveratrol and ketorolac through isobolographic analysis. CD1 mice were used to study the antinociceptive effect of this combination using the formalin test and the study was divided into two phases. In the first phase, four individual doses of each drug were evaluated, totaling eight testing groups. From these data, the median effective doses (ED 50 ) of each drug were calculated. In the second phase, four testing groups were used to evaluate the combination of sub-doses of both drugs and obtain the experimental ED 50 . To evaluate gastric damage, five groups were employed, including indomethacin, vehicle, resveratrol, ketorolac, and combined resveratrol and ketorolac groups. Stomach samples from the mice were taken after 5 h of treatment, and the area of the ulcers was determined. Resveratrol plus ketorolac elicited a reduction in nociceptive behavior during both phases of the formalin test, and isobologram analysis revealed that the theoretical and experimental ED 50 values of resveratrol and ketorolac did not differ significantly, implying an additive interaction between the drugs. Additionally, the drug combination did not generate gastric ulcers, thus enhancing the desired effects without increasing the adverse effects. Consequently, these findings substantiate the efficacy of the resveratrol and ketorolac combination in the formalin test, thereby highlighting its potential as a viable alternative for alleviating pain.

Findings on the effects of iron on heart failure (HF) hospitalizations and mortality among patients with iron deficiency (ID) and HF remain conflicting across different studies. We performed a meta-analysis of clinical trials assessing the clinical, hematic and cardiovascular benefits of treating ID in HF patients. We completed a systematic search for studies comparing IV iron to placebo in HF patients with ID. The primary outcomes were rates of HF hospitalization and all-cause mortality. Secondary outcomes included change in hematic values, New York Heart Association (NYHA) class and ejection fraction. We applied a random-effects model with planned sensitivity analyses of studies with skewed effect sizes. Nine studies were included with a total of 2,261 patients. Analysis revealed that treatment of HF patients with IV iron replacement significantly reduced the odds of HF hospitalization (odds ratio (OR): 0.44; 95% confidence interval (CI): 0.24 to 0.78; p=0.005, I 2 =67%),) but did not significantly impact all-cause mortality compared to placebo (OR: 0.89; 95%, CI: 0.67 to 1.19; p=0.44, I 2 : 0%). Analysis showed that IV iron treatment group had significantly higher serum ferritin, transferrin saturation and hemoglobin (Hb) levels. They also had lower NYHA class -1.90 (95% CI (-2.91 to -0.89); p<0.001, I 2 :89%) with higher ejection fraction 0.50 (95% CI (0.09 to 0.90) p=0.016, I 2 :86%). Treatment with IV iron in HF patients with ID is associated with a significant reduction of HF hospitalization but no effects on all-cause mortality. There were also significant increases in hematic values and ejection fraction with a reduction in NYHA class., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Ogugua et al.)

(5) Educational videos are essential in the training of Nursing professionals. to evaluate the diverse scientific evidence on the methodologies used by Nursing professionals in the production of educational videos., Method: an integrative review. The search for primary studies was carried out in the CINAHL, LILACS and MEDLINE/PubMed databases. The sample consisted of 19 research studies. The methodological quality of the studies included was assessed using a tool proposed by the Johns Hopkins Nursing Evidence-Based Practice and the results were analyzed in a descriptive form., Results: the methodological stages used for the process to elaborate and make the videos include pre-production, production and post-production. The studies reveal that, for the most part, the stages were properly applied and/or described by the authors, in addition to contemplating the method adopted. However, in 14 studies there was no use of a methodological framework to ensure rigor in their conduction and in 11 presented validation by the target audience., Conclusion: the synthesis of knowledge showed that there is still a need for attention for the construction of educational videos regarding the methodological framework and validation by the target population. The rigorous execution of the methodological procedures necessary for the development of educational videos, aiming to encourage the acquisition of essential skills for the creation of high-quality teaching materials.

Objective: To identify and map the available evidence on the implementation of public health policies directed at individuals with rare diseases, and to compare the implementation of these health policies between Brazil and other countries., Method: A scoping review guided by the PRISMA-ScR and JBI checklists. The search for articles was conducted in eight electronic databases, MEDLINE/Pubmed, Embase, Cochrane Library, Web of Science, Scopus, CINAHL, PsycINFO, and LILACS, using controlled descriptors, synonyms, and keywords combined with Boolean operators. All steps of this review were independently conducted by two researchers. The selected studies were classified by evidence hierarchy, and a generic quantitative tool was used for the assessment of the studies., Results: A total of 473 studies were identified, of which 13 which met all the inclusion criteria were selected and analyzed. Of these studies, 61.5% (n = 8) had final scores equal to or greater than 70%, i.e., they were classified by this tool as being well-reported. The comparative analysis of international rare diseases demonstrates that public authorities' priorities and recommendations regarding this topic also permeate and apply to the Brazilian context., Conclusions: The evaluation and monitoring of public policies directed at rare disease patients are urgent and necessary to improve and implement such policies with less bureaucracy and more determination for this unique population that requires timely and high-quality care.

In this present article the draft sequence data for Clostridium perfringens FA, which was isolated from the faecal material of a critically endangered African Wild dog, is reported. The bacterium is widely distributed in the environment and in the normal intestinal flora of humans and animals. The genome of strain C. perfringens FA was assembled into 21 contigs with a total length of 3, 044, 349 bp and a GC content of 28.20%. There are 2742 CDS, 70 tRNAs and 5 rRNAs. Five putative virulence genes were detected. There were no plasmid replicons found. The genome of few environmental isolates has been sequenced. The draft genome of strain FA can be compared to disease causing isolates cultured from humans to aid in a better understanding of the pathogenesis of the bacterium., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Author(s).)

Introduction: Outpatient care for children and adolescents with chronic conditions needs to be continuous and programmed, encompassing comprehensive care, with periodically scheduled consultations, exams, and procedures, to promote quality of life and reduce mortality. In the context of the new coronavirus pandemic, however, outpatient care for children and adolescents with chronic conditions, in person, was hampered in favor of social isolation, a necessary sanitary measure to reduce and prevent the spread of Coronavirus Disease 2019. In response to this need, studies suggest telehealth in pediatrics as a fertile and expanding field especially in times of pandemics. Here, we aimed to map the evidence related to telehealth in outpatient care for children and adolescents with chronic conditions during the COVID-19 pandemic, to identify which strategies were implemented and their impacts on the continuity of care., Methods: A scoping review protocol is reported and guided by the Scoping Reviews Manual of the Joanna Briggs Institute. The search for evidence will cover the following databases: MEDLINE/PubMed, Cochrane Libary; Embase; Web of Science; Scopus; Cinahl and PsycINFO, plus additional sources, such as The British Library, Google Scholar, and Preprints [medRXiv]. No date or language restrictions will be employed in this scoping review. Two independent researchers will conduct the search strategy, study selection, data charting, and data synthesis., Results: The findings will be presented through tables, charts, narrative summaries, and assessed based on the type of data charted as well as outcomes. Additionally, the meaning of these findings will be considered as they relate to the guiding question, the characterization and measurement of the impact of different telehealth modalities used in outpatient care for children and adolescents with chronic conditions during the COVID-19 pandemic, and the implications for practice and further research., Discussion: To the best of our knowledge, this will be the first scoping review to look specifically at the telehealth modalities to be used in outpatient care for children and adolescents with chronic conditions during the COVID-19 pandemic. We expect that our results will be of interest to practitioners as well as researchers concerned with this particular emerging issue in the pandemic context. Also, the plans for the dissemination of this study comprise peer-reviewed publication and conference presentations., Trial Registration: Open Science Framework Registration: osf.io/5pqgu., Competing Interests: The authors have declared that no competing interests exist.

The African wild dog (AWD) (Lycaon pictus) is a critically endangered species. These animals are hypercarnivores, hunting mostly medium-sized antelope. In this study, using bacterial tag-encoded FLX-Titanium amplicon pyrosequencing (bTEFAP ® ), the microbiota in the fecal material of AWDs living in the Great Plains Zoo & Delbridge Museum of Natural History was investigated. In both samples, the most predominant bacterial phylum was the Firmicutes with members of the genus Blautia spp. being the most dominant bacteria., (© 2021.

Purpose: This study aimed to uncover the fertility-related concerns and uncertainties in adolescent and young adult (AYA) childhood cancer survivors. Methods: In this qualitative study, participants were recruited from an oncohematology outpatient clinic at a university hospital in Brazil. Twenty-four AYA cancer survivors, aged 18- 24 years (13 men and 11 women), participated in individual semistructured interviews focusing on two parts-sociodemographic and clinical variables and guiding questions that enabled understanding of the concerns and uncertainties regarding the risks of infertility and their impact on relationships and the need for guidance. Data were analyzed using inductive thematic analysis. Results: Four themes were identified from the data-(1) knowledge about fertility, (2) emotional impact and fertility-related uncertainty, (3) sharing the possible risk of infertility with partners, and (4) need for information on possible loss of fertility. Conclusion: The meanings attributed to the loss of fertility after cancer treatment uncovered the need for health professionals to organize survivor services in line with the survivors' needs, and include reproductive concerns and uncertainties in this planning. The study results provide insights for the development of health care services that meet the real needs of this particular population that has long-term follow-up demands.

Tessaria dodoneifolia [Asteraceae] is traditionally employed in Northwestern Argentina for fungal infections treatment. We report the antifungal activity guided isolation and identification of substances from aerial parts of this species, both individually and in combination with fluconazole (FLU), against Candida albicans strains. Two antifungal flavanones were identified as naringenin (NAR) and pinocembrin (PIN). These compounds could individually inhibit the growth of C. albicans strains. Combinations of NAR and PIN with FLU were synergistic against the FLU resistant and sensitive C. albicans strains. Genotoxic and cytotoxic evaluations were also performed. NAR, PIN and their combinations with FLU did not have a genotoxic effect on Bacillus subtilis rec strains. Finally, these compounds did not show cytotoxicity at concentrations below 80 μg/mL., (© 2020 Published by Elsevier Ltd.)

By early-2016, the international community began to pressure Brazil for a stronger policy response to Zika. In contrast to what was seen in the past, however, these international pressures did not elicit such a response. In this article, we explore why this was the case, reviewing the government's policy response and the broader political and economic context shaping this response. The authors used single case study analysis and qualitative sources, such as books, journal articles, and government policy reports to support their empirical claims. We found that despite increased international pressures from the WHO, domestic political factors and economic recession hampered the government's ability to strengthen its health systems response to Zika. Consequently, those states most afflicted by Zika have seen policy initiatives that lack sufficient funding, administrative and human resource capacity. This study revealed that despite a government's deep foreign policy history of positively responding to international pressures through a stronger policy response to health epidemics, a sudden change in government, rising political instability, and economic recession can motivate governments to abandon this foreign policy tradition and undermine its response to new public health threats., Competing Interests: Competing interests: None declared.

We aimed to detect DNA of Borrelia burgdorferi in whole blood and serum samples of patients with clinical symptoms and epidemiology compatible with Brazilian Lyme-like disease. Four patients with positive epidemiological histories were recruited for the study. Blood samples were collected, screened by serologic testing by ELISA and Western blotting and molecular identification of B. burgdorferi by amplifying a fragment of the conserved gene that synthesizes the hook flagellar flgE. The results showed positive serology and for the first time, the presence of B. burgdorferi sensu lato in humans in the Midwest region of Brazil. The resulting sequences were similar to GenBank corresponding sequences of B. burgdorferi flgE gene. By neighbor-joining the phylogenetic analysis, the flgE sequence of the Brazilian strain clustered in a monophyletic group with the sequence of B. burgdorferi sensu lato under 100% bootstrap support. This study opens up promising perspectives and reinforces the need for additional studies to determine the epidemiological characteristics of the disease, as well as the impact of the prevalence of Brazilian borreliosis in Mato Grosso do Sul State, Brazil., (Copyright © 2017 Elsevier Editora Ltda.

Epidermolysis bullosa is a genetic disease characterized by an alteration in the proteins involved in the binding of the dermis to the epidermis. It can also affect the mucous, causing inner injuries. It is classified into three main types: simple, junctional and dystrophic, and, depending on its inheritance, can be dominant and recessive. There is no specific treatment and its evolution is chronic, significantly affecting the quality of life of patients. The caretaking required by people with this disease is a real challenge for the nursing professional and it is very important to have the support of his family. In our case we explain how we got to modify the healthcare that this patient received for years, who was averse to changes, both himself and his family. Counseled by DEBRA nurses, the association of those affected by this disease and their families, and also by a cures-specialist nurse that DEBRA introduced to us, they helped us convincing thepatient and his family of the need of changing the hydrophilic cotton gauze dipped in antibiotic ointment with different concentrations depending on the zone, to more advanced cures, with dressings for wound healing in a moist environment, gaining time and comfort, given that previous cures were slow and painful. The pain, odor and time needed for healing has decreased. The patient has gained comfort by reducing the time spent on cures. Nursing has achieved its goal to improve the quality of the patient's life.

An interferometric method is implemented in order to accurately assess the thermal fluctuations of a micro-cantilever sensor in liquid environments. The power spectrum density (PSD) of thermal fluctuations together with Sader's model of the cantilever allow for the indirect measurement of the liquid viscosity with good accuracy. The good quality of the deflection signal and the characteristic low noise of the instrument allow for the detection and corrections of drawbacks due to both the cantilever shape irregularities and the uncertainties on the position of the laser spot at the fluctuating end of the cantilever. Variation of viscosity below 0:03mPa·s was detected with the alternative to achieve measurements with a volume as low as 50 µL.

The aim of this study was to obtain pharmacokinetic data for the anxiolytic compound galphimine-A (G-A) from Galphimia glauca. G-A is the most abundant anxiolytic compound in this plant, while Galphimine-E (G-E) is the most abundant galphimine, but inactive. G-E was transformed chemically into G-A. The pharmacokinetic study was carried out in ICR mice, which were orally administered a single 200 mg/kg dose of G-A. Samples of blood and brain were taken at different times after administration of G-A. Previously, we established the validation of methods for determining the concentration of G-A. The G-A was detected in plasma 5 min after oral administration, and its concentration reached 2.47 μg/mL. Data from concentration-time curves allowed us to establish the main pharmacokinetic parameters in two models: one- and/or two-compartment. C(max) values were 3.33 and 3.42 μg/mL respectively, likewise AUC(0→1440 min) were 1,951.58 and 1,824.95 μg/mL·min. The G-A in brain tissue was noted to cross the blood-brain barrier, reaching C(max) 2.74 μg/mL, T(max) 81.6 min, and then drop gradually to 0.32 μg/mL detected at 24 h. The presence of G-A in brain tissue, confirmed that this anxiolytic compound can access the target organ and acts directly on the CNS.

The increased frequency and dissemination of enterobacteria resistant to various antimicrobials is currently worldwide concern. In January 2010, a 94-year-old patient with chronic lymphocytic leukemia was admitted to the University Hospital. This patient died 21 days after hospitalization due to the clinical worsening. Klebsiella pneumoniae producing of extended-spectrum β-lactamases (ESBLs) was isolated of urine culture. This bacterium demonstrated resistance to ceftazidime, ciprofloxacin, levofloxacin, ertapenem and imipenem. Susceptibility to cefoxitin, cefepime, meropenem, colistin and tigecycline. This study reports the first case of infection by Klebsiella pneumoniae carrying the bla(kpc) gene in the State of Mato Grosso do Sul, Brazil.

Ethnopharmacological Relevance: Hibiscus sabdariffa L. (Malvaceae) populary known in Mexico as "Jamaica", "flor de Jamaica", has widely used in Mexican Traditional Medicine as antihypertensive and diuretic, although the latter activity has been reported the present work show evidence about the diuretic, natriuretic and potassium-sparing effects., Aim of the Study: To evaluate the diuretic activity of Hibiscus sabdariffa aqueous extract on in vivo and in situ models., Materials and Methods: The Hibiscus sabdariffa aqueous extract was administrated in increasing doses and evaluated the diuresis produced and disposal of electrolytes. Moreover, in isolated kidney was determined the renal filtration rate with plant extract, furosemide and amiloride., Results: The yield of Hibiscus sabdariffa aqueous extraction was 28.3% and the chemical standardization from 1 g of extract was: 56.5 mg delphinidin-3-O-sambubioside, 20.8 mg/g cyanidin-3-O-sambubioside, 3.2 mg/g quercetin, 2.1 mg/g rutin and 2.7 mg/g chlorogenic acid. The diuretic and natriuretic effect of Hibiscus sabdariffa aqueous extract showed a dose-dependent behavior. The pharmacological constants of natriuretic effect was ED50=86 mg/kg and Emax=0.9 mEq/100 g/5 h. In the model of kidney in situ was observed that renal filtration increased 48% with the aqueous extract of Hibiscus sabdariffa and an additive effect when was perfuse with furosemide., Conclusion: The compound presents in Hibiscus sabdariffa as quercetin had effect on the vascular endothelium causing oxide nitric release, increasing renal vasorelaxation by increasing kidney filtration. Therefore, the diuretic effect of Hibiscus sabdariffa may be mediated by nitric oxide release., (Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.)

Von Hippel-Lindau disease is a dominant autosomal genetic condition with variable penetrance and expressivity. It is characterized by hemangioblastomas in multiple organs but mainly in the retina and cerebellum. There is a predisposition to carcinoma. We report a cesarean section in a 28-year-old woman with von Hippel-Lindau disease. She had no neurologic symptoms at the time of the operation but a history of ocular and cerebellar involvement and several procedures to remove cerebellar hemangioblastomas. Epidural anesthesia was chosen given that there was no nervous system involvement at the time of surgery.

The main objective of this study was to analyze emotional response to a set of everyday emotional visual stimuli unrelated to drug use. Two groups of prescribed opiate drug abusers (heroin+methadone vs. methadone-only groups) currently participating in the Andalusian Experimental Prescribed Drug Program (Programa Experimental de Prescripcion de Estupefacientes de Andalucia, PEPSA) were studied, and comparisons made between them, within them for different phases, and between them and a normative group of nonusers. For this purpose we used the I.C.E.R.E., an instrument based on the I.A.P.S. (International Affective Picture System) and on Peter Lang's S.A.M. (Self-Assessment Manikin). The results showed patterns of emotional response in the opiate users, compared to the non-users, characterized by a lower rating of the everyday natural stimuli of a pleasant nature and a greater sensitivity to the stimuli of a neutral and negative nature. These patterns were quite stable even in different clinical situations and stages of development of the P.E.P.S.A.

Our study examined the relation between neuropsychological impairment of executive functions and explanatory styles, according to the Abramson model of learned helplessness in humans, in a sample of substance abusers. Thirty-eight polysubstance abusers were assessed during an abstinence period using a selective neuropsychological battery for the evaluation of the executive functions, as well as the Attributional Style Questionnaire (ASQ) for the assessment of the three dimensions of explanatory style: Internality-Externality, Stability-Instability and Globality-Specificity. Multiple regression analyses showed significant relationships among performance on different neuropsychological tasks sensitive to executive functions and characteristic cognitive styles. The results showed the performance on cognitive flexibility and response inhibition tasks is directly related to making more internal attributions for positive situations, and inversely related to the appearance of more stable attributions for negative events. Likewise, adequate performance on working memory tasks was related to development of more global attributions for failures. These results are partially congruent with the learned helplessness model and particularly relevant for the clinical management of substance abusers and the success on the treatment and rehabilitation of these subjects.

The usual agent of visceral leishmaniasis in the Old World is Leishmania donovani, which typically produces systemic diseases in humans and mice. L. donovani has developed efficient strategies to infect and persist in macrophages from spleen and liver. Dendritic cells (DC) are sentinels of the immune system. Following recognition of evolutionary conserved microbial products, DC undergo a maturation process and activate antigen-specific naïve T cells. In the present report we provide new insights into how DC detect Leishmania in vivo. We demonstrate that in both C57BL/6 and BALB/c mice, systemic injection of L. donovani induced the migration of splenic DC from marginal zones to T-cell areas. During migration, DC upregulated the expression of major histocompatibility complex II and costimulatory receptors (such as CD40, CD80, and CD86). Leishmania-induced maturation requires live parasites and is not restricted to L. donovani, as L. braziliensis, L. major, and L. mexicana induced a similar process. Using a green fluorescent protein-expressing parasite, we demonstrate that DC undergoing maturation in vivo display no parasite internalization. We also show that L. donovani-induced DC maturation was partially abolished in MyD88-deficient mice. Taken together, our data suggest that Leishmania-induced DC maturation results from direct recognition of Leishmania by DC, and not from DC infection, and that MyD88-dependent receptors are implicated in this process.

Cells of the dendritic cell (DC) lineage, by their unique ability to stimulate naive T cells, may be of crucial importance in the development of protective immune responses to Leishmania parasites. The aim of this study was to compare the impact of L. major infection on DCs in BALB/c (susceptible, developing Th2 responses), C57BL/6 (resistant, developing Th1 responses), and tumor necrosis factor (TNF)(-/-) C57BL/6 mice (susceptible, developing delayed and reduced Th1 responses). We analyzed by immunohistochemistry the phenotype of infected cells in vivo. Granulocytes (GR1(+)) and macrophages (CD11b(+)) appear as the mainly infected cells in primary lesions. In contrast, cells expressing CD11c, a DC specific marker, are the most frequently infected cells in draining lymph nodes of all mice tested. These infected CD11c(+) cells harbored a particular morphology and cell surface phenotype in infected C57BL/6 and BALB/c mice. CD11c(+) infected cells from C57BL/6 and TNF(-/-) C57BL/6 mice displayed a weak parasitic load and a dendritic morphology and frequently expressed CD11b or F4/80 myeloid differentiation markers. In contrast, some CD11c(+) infected cells from BALB/c mice were multinucleated giant cells. Giant cells presented a dramatic accumulation of parasites and differentiation markers were not detectable at their surface. In all mice, lymph node CD11c(+) infected cells expressed a low major histocompatibility complex II level and no detectable CD86 expression. Our results suggest that infected CD11c(+) DC-like cells might constitute a reservoir of parasites in lymph nodes.
