ABSTRACT

ABSTRACT This study aimed to verify the use of photobiomodulation in swallowing difficulties in individuals who had a severe form of COVID-19. This case report was based on a quasi-experimental, quantitative study, with primary data collected from a non-probabilistic sample of 13 adults (aged ≥ 19 to < 60 years) of both sexes, who had the severe form of COVID-19. Swallowing was assessed with the Dysphagia Risk Assessment Protocol, and the intervention used photobiomodulation. Descriptive statistics were used. It was found that all research participants' risk for dysphagia in water and pudding swallowing tests improved from before to after the intervention. It can be concluded that photobiomodulation had positive results in speech-language-hearing practice to treat swallowing difficulties in adults who were affected by the severe form of COVID-19, intubated, tracheostomized, and needed an alternative feeding route, as the swallowing difficulties improved.


RESUMO O objetivo foi verificar o uso da fotobiomodulação na dificuldade de deglutição em indivíduos que desenvolveram a forma grave da COVID-19. Trata-se de um relato de casos, a partir de um estudo quase experimental, quantitativo, com coleta de dados primários e com amostra não probabilística, realizado com 13 indivíduos adultos (idade ≥ 19 a < 60 anos) de ambos os sexos, que tiveram a forma grave da COVID-19. Foi realizada a avaliação da deglutição pelo Protocolo de Avaliação para o Risco de Disfagia (PARD) e a intervenção com fotobiomodulação. Foi utilizada a estatística descritiva. Verificou-se que todos os participantes da pesquisa apresentaram melhora no risco para disfagia no teste de deglutição de água e de alimento pastoso do momento pré para o pós-intervenção. Pode-se concluir que a utilização da fotobiomodulação na prática fonoaudiológica para tratar a dificuldade de deglutição dos adultos que foram acometidos pela forma grave da COVID-19, intubados, traqueostomizados e necessitaram fazer uso de via alternativa de alimentação, trouxe resultados positivos, com melhora da dificuldade de deglutição.

ABSTRACT

In this work, the deoxygenation of organic liquid products (OLP) obtained through the thermal catalytic cracking of palm oil at 450 °C, 1.0 atmosphere, with 10% (wt.) Na2CO3 as a catalyst, in multistage countercurrent absorber columns using supercritical carbon dioxide (SC-CO2) as a solvent, with an Aspen-HYSYS process simulator, was systematically investigated. In a previous study, the thermodynamic data basis and EOS modeling necessary to simulate the deoxygenation of OLP was presented. This work addresses a new flowsheet, consisting of 03 absorber columns, 10 expansions valves, 10 flash drums, 08 heat exchanges, 01 pressure pump, and 02 make-ups of CO2, aiming to improve the deacidification of OLP. The simulation was performed at 333 K, 140 bar, and (S/F) = 17; 350 K, 140 bar, and (S/F) = 38; 333 K, 140 bar, and (S/F) = 25. The simulation shows that 81.49% of OLP could be recovered and that the concentrations of hydrocarbons in the extracts of absorber-01 and absorber-02 were 96.95 and 92.78% (wt.) on a solvent-free basis, while the bottom stream of absorber-03 was enriched in oxygenated compounds with concentrations of up to 32.66% (wt.) on a solvent-free basis, showing that the organic liquid products (OLP) were deacidified and SC-CO2 was able to deacidify the OLP and obtain fractions with lower olefin contents. The best deacidifying condition was obtained at 333 K, 140 bar, and (S/F) = 17.

ABSTRACT

In December 2019, a pandemic emerged due to a new coronavirus that imposed various uncertainties and discoveries. It has been reported that diabetes is a risk factor for worst outcomes of COVID-19 and also that SARS-CoV-2 infection was correlated with the occurrence of diabetic ketoacidosis (DKA) in patients. The aim of this work is to discuss this correlation emphasizing the main case reports from 2020 while exploring the management of DKA during the course of COVID-19. Web of Science, PubMed, and Scopus databases were searched using two sets of Medical Subject Heading (MeSH) search terms or Title/Abstract words: Coronavirus Infections (Coronavirus Infections, Middle East Respiratory Syndrome, COVID-19) and Diabetic Ketoacidosis (Diabetic Ketoacidosis, Diabetic Acidosis, Diabetic Ketosis). There is a clear correlation between COVID-19 and DKA. The SARS-Cov-2 infection may precipitate both a hyperglycemic state and ketoacidosis occurrence in patients with diabetes and nondiabetic patients, which may lead to fatal outcomes. DKA in patients with COVID-19 may increase risk and worse outcomes. Hence, the SARS-Cov-2 infection presents a new perspective toward the management of glycemia and acidosis in patients with diabetes and nondiabetic patients, highlighting the need for rapid interventions to minimize the complications from COVID-19 while reducing its spreading.

ABSTRACT

INTRODUCTION: Ivermectin is a drug with antiviral properties and has been proposed as an alternative treatment for patients with COVID-19, in some countries; however, there is limited evidence to support its clinical use. Accordingly, the aim of this review and meta-analysis is to obtain superior evidence on the effectiveness and safety of ivermectin in treatment of COVID-19. METHODS AND ANALYSIS: We will search in the medical databases and International Clinical Trials Registry Platform databases for randomised clinical trials and quasi-randomised trials published from December 2019. The criteria for inclusion are that infection needs to be confirmed by a real-time PCR or serology test, and the effect of ivermectin has been compared with placebo, symptomatic treatment or no treatment. We will exclude observational studies and clinical trials that involved patients with symptoms suggestive of COVID-19, but without a laboratorial diagnosis. Outcomes of interest include mortality, time to symptom resolution, time of hospitalisation, frequency of invasive mechanical ventilation and extracorporeal membrane oxygenation, incidence of severe acute respiratory syndrome, admission to intensive care unit, viral load, PCR-negative status, percentage of infection after prophylactic use, and total incidence of adverse and side effects. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Two reviewers will independently select the studies and assess their eligibility. Two other reviewers will independently extract data from each study. Meta-analysis will then be carried out using fixed-effects or random-effects model, using the mean difference for continuous outcomes and the relative risk for dichotomous outcomes. Bias risk will be assessed using the Cochrane risk-of-bias tool. The quality of evidence for each outcome will be assessed using GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology. Review Manager V.5.3.5 will be used for synthesis and subgroup analysis. ETHICS AND DISSEMINATION: Owing to the nature of the review, ethical approval is not required. The results will be disseminated through peer-reviewed publications. PROSPERO REGISTRATION NUMBER: CRD42020197395.

ABSTRACT

Quinones are plant-derived secondary metabolites that present diverse pharmacological properties, including antibacterial, antifungal, antiviral, anti-inflammatory, antipyretic and anticancer activities. In the present study, we evaluated the cytotoxic effect of a new naphthoquinone 6b,7-dihydro-5H-cyclopenta [b]naphtho [2,1-d]furan-5,6 (9aH)-dione) (CNFD) in different tumor cell lines. CNFD displayed cytotoxic activity against different tumor cell lines, especially in MCF-7 human breast adenocarcinoma cells, which showed IC50 values of 3.06 and 0.98 µM for 24 and 48 h incubation, respectively. In wound-healing migration assays, CNFD promoted inhibition of cell migration. We have found typical hallmarks of apoptosis, such as cell shrinkage, chromatin condensation, phosphatidylserine exposure, increase of caspases-9 and-3 activation, increase of internucleosomal DNA fragmentation without affecting the cell membrane permeabilization, increase of ROS production, and loss of mitochondrial membrane potential induced by CNFD. Moreover, gene expression experiments indicated that CNFD increased the expression of the genes CDKN1A, FOS, MAX, and RAC1 and decreased the levels of mRNA transcripts of several genes, including CCND1, CDK2, SOS1, RHOA, GRB2, EGFR and KRAS. The CNFD treatment of MCF-7 cells induced the phosphorylation of c-jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinases (MAPKs) and inactivation of extracellular signal-regulated protein kinase 1/2 (ERK1/2). In a study using melanoma cells in a murine model in vivo, CNFD induced a potent anti-tumor activity. Herein, we describe, for the first time, the cytotoxicity and anti-tumor activity of CNFD and sequential mechanisms of apoptosis in MCF-7 cells. CNFD seems to be a promising candidate for anti-tumor therapy.

ABSTRACT

Classically, the endocannabinoid system (ECS) consists of endogenous lipids, of which the best known are anandamide (AEA) and 2 arachidonoylglycerol (2-AG), their enzyme machinery for synthesis and degradation and their specific receptors, cannabinoid receptor one (CB1) and cannabinoid receptor two (CB2). However, endocannabinoids also bind to other groups of receptors. Furthermore, another group of lipids are considered to be endocannabinoids, such as the fatty acid ethanolamides, the fatty acid primary amides and the monoacylglycerol related molecules. Recently, it has been shown that the hemopressin peptide family, derived from α and ß chains of hemoglobins, is a new family of cannabinoids. Some studies indicate that hemopressin peptides are expressed in the central nervous system and peripheral tissues and act as ligands of these receptors, thus suggesting that they play a physiological role. In this review, we examine new evidence on lipid endocannabinoids, cannabinoid receptors and the modulation of their signaling pathways. We focus our discussion on the current knowledge of the pharmacological effects, the biosynthesis of the peptide cannabinoids and the new insights on the activation and modulation of cannabinoid receptors by these peptides. The novel peptide compounds derived from hemoglobin chains and their non-classical activation of cannabinoid receptors are only starting to be uncovered. It will be exciting to follow the ensuing discoveries, not only in reference to what is already known of the classical lipid endocannabinoids revealing more complex aspects of endocannabinoid system, but also as to its possibilities as a future therapeutic tool.

ABSTRACT

Coronavirus disease 2019 (COVID-19) caused by the highly pathogenic SARS-Cov-2 virus, was declared as a pandemic by the World Health Organization (WHO) in March 2020. Its main clinical manifestations are related to airway involvement; however, there is extrapulmonary impairment in some cases. Given this context, this literature review aims to identify the ophthalmological conditions caused by infection with the novel coronavirus. Although ocular findings do not include the standard clinical presentation of the disease, there are reports of some ophthalmological changes in COVID-19 patients, and conjunctivitis is the most common among these.

ABSTRACT

In this study, continuous casting is proposed as a suitable approach to scale up the production of gelatin-cellulose nanocrystals (CNCs) bionanocomposites. The processing conditions and bionanocomposite properties were established based on the ζ-potential and gelatin content, and CNCs concentration, respectively. Gelatin film-forming solution at 20 wt% was required for proper continuous casting processing, leading to a productivity of 0.20 m2 film/min, which was at least 1000-fold higher than that of the classical bench casting. The gelatin-CNCs bionanocomposites displayed transparency, flexibility, and improved UV-barrier and thermal properties. Adding only 0.5 wt% of CNCs resulted in an increase of 77 % and 48 % in the tensile strength and Young's modulus of gelatin, respectively. Comparison with previous nanocellulose-based nanocomposites pointed out the relatively superior performance of the gelatin-CNCs bionanocomposites obtained by continuous casting for various applications, including flexible food packaging.

ABSTRACT

Summary Hemoglobinopathies are a group of hereditary diseases that cause quantitative or qualitative changes in the shape, function or synthesis of hemoglobin. One of the most common is sickle cell anemia, which, due to sickling of erythrocytes, causes vaso-occlusive phenomena. Among the possible ocular manifestations, the most representative is retinopathy, which can lead to blindness if left untreated. Therefore, periodic ophthalmologic monitoring of these patients is important for early diagnosis and adequate therapeutic management, which can be done localy by treating the lesions in the eyes, or systemically.


Resumo As hemoglobinopatias são um grupo de doenças hereditárias que causam alterações quantitativas ou qualitativas no formato, na função ou na síntese de hemoglobinas. Uma das mais comuns é a anemia falciforme, cuja patogenia é a foicização das hemácias, causando fenômenos vaso-oclusivos. Dentre as manifestações oculares possíveis, a mais representativa é a retinopatia, que pode levar à cegueira caso não seja tratada. Por isso, é importante que haja o acompanhamento oftalmológico periódico desses pacientes, a fim de obter diagnóstico precoce e abordagem terapêutica adequada. Esta última pode ser de maneira direta, com tratamento das lesões oculares, ou de forma sistêmica.

ABSTRACT

BACKGROUND: Recent studies have shown that myocardial perfusion imaging (MPI) in cadmium-zinc-telluride (CZT) cameras allow faster exams with less radiation dose but there are little data comparing its prognosis information with that of dedicated cardiac Na-I SPECT cameras OBJECTIVE: The objective of this study is to compare the prognostic value of MPI using an ultrafast protocol with low radiation dose in a CZT-SPECT and a traditional one. METHODS: Group 1 was submitted to a two-day MIBI protocol in a conventional camera, and group 2 was submitted to a 1-day MIBI protocol in CZT camera. MPI were classified as normal or abnormal, and perfusion scores were calculated. Propensity score matching methods were performed RESULTS: 3554 patients were followed during 33±8 months. Groups 1 and 2 had similar distribution of age, gender, body mass index, risk factors, previous revascularization, and use of pharmacological stress. Group 1 had more abnormal scans, higher scores than group 2. Annualized hard events rate was higher in group 1 with normal scans but frequency of revascularization was similar to normal group 2. Patients with abnormal scans had similar event rates in both groups CONCLUSION: New protocol of MPI in CZT-SPECT showed similar prognostic results to those obtained in dedicated cardiac Na-I SPECT camera, with lower prevalence of hard events in patients with normal scan.

ABSTRACT

RESUMO Objetivo: Determinar a adesão aos colírios antiglaucomatosos em pacientes do Projeto Glaucoma (Ministério da Saúde) por meio da escala de Morisky de 8 itens. Métodos: Foi realizado um estudo transversal por meio de questionário aplicado a 237 pacientes diagnosticados com glaucoma inscritos regularmente no Projeto Glaucoma do Instituto de Olhos de Maceió, adaptando a escala de Morisky já validada em português para colírios. As variáveis foram a adesão aos colírios antiglaucomatosos, idade, sexo, raça, tempo de diagnóstico do glaucoma, número de colírios utilizados, doenças sistêmicas, escolaridade, perfil de visão (ruim, razoável ou boa) e os fatores correlacionados com a adesão. A análise estatística entre as variáveis foi realizada com os testes estatísticos do Quiquadrado para as variáveis categóricas e Teste U de Mann-Whitney para as contínuas, considerando um nível de significância de 5%. Resultados: A adesão aos colírios foi de 54%. A idade e o número de colírios (p=0,02 e 0,03 respectivamente) foram estatisticamente relevantes, assim como a qualidade de visão também foi (p<0,001) para o não uso adequado do tratamento. O motivo mais comum tanto no grupo de aderentes como no de não aderentes foi o esquecimento (23% e 76,15% respectivamente). Conclusão: Utilizando a escala de Morisky adaptada para colírios antiglaucomatosos a adesão aos colírios foi de 54% .


ABSTRACT Objective: To determine adherence to glaucoma eye drops in patients from Glaucoma Project (Ministry of Health) by Morisky scale of 8 items. Methods: We conducted a cross-sectional study through a questionnaire applied to 237 patients diagnosed with glaucoma regularly enrolled in the Glaucoma Project at Institutode Olhos de Maceio, adapting the Morisky scale, already validated in Portuguese, for eyedrops. The variables were adherence to antiglaucoma eyedrops, age, sex, race, glaucoma diagnosis time, eyedrops number used, systemic diseases, education, subjective vision (categorized in bad, reasonable or good) and the factors correlated with poor adherence. Statistical analysis between variables was performed with the statistical test Chi-square test for categorical variables and test Mann-Whitney test for continuous outcomes, considering a 5% significance level. Results: The rate of adherence to the glaucoma drops was 54%. The age and number of drops (p = 0.02 and 0,03 respectively), and quality of vision (p<0,001) were statistically significant for the inappropriate use of the therapy and the most common reason both adherent group as the non-adherent was forgetfulness (23% and 76,15% respectively). Conclusion: Using the Morisky scale adapted to antiglaucoma eyedrops the adherence was 54%.

ABSTRACT

Knowledge on chemical components of the post -hatching eggshell of reptiles may provide indicators of the quality of the diet offered to females kept in captivity. Therefore, the objective of this study was to investigate the chemical characteristics of the calcareous layer, as well as the thickness of Podocnemis expansa post-hatching eggshells. Eggshell thickness was 183±1.405 µm. This value is similar to that of the eggs of other Testudines with flexible eggshells. As for the chemical composition, the following percentages were observed: nitrogen 7.983 ± 0.054; crude protein 49.91 ± 0.324; crude fat 0.068 ± 0.002; mineral matter 20.302 ± 0.807; calcium 13.374 ± 0.647; and phosphorus 0.176 ± 0.003. Knowledge on chemical composition of the eggshell may aid the nutrition of P. expansa raised in commercial facilities, once this species is an alternative and promising source of exotic meat.

Assim, este trabalho visa investigar os aspectos químicos que compõem a camada calcária, bem como a espessura da casca do ovo de Podocnemis expansa no período pós-eclosão. A espessura média da casca dos ovos foi de 183 ± 1,405 µm. Esta espessura é condizente com ovos de outros Testudines com casca flexível. Para os constituintes químicos, foram encontrados os seguintes valores médios percentuais: nitrogênio 7,983 ± 0,054, proteína bruta 49,91 ± 0,324, gordura bruta 0,068 ± 0,002, matéria mineral 20,302 ± 0,807, cálcio 13,374 ± 0,647 e fósforo 0,176 ± 0,003. Este conhecimento sobre a composição química da casca poderá auxiliar na criação em escala comercial dessa espécie, uma vez que a P. expansa tem se apresentado como fonte alternativa e promissora de carne exótica.

ABSTRACT

Introdução: O conhecimento dos fatores de risco relacionados às complicações do acesso vascular em pacientes submetidos à estratégia invasiva precoce permite adotar estratégias capazes de minimizá-las. Métodos: Realizamos subanálise do estudo ARISE, com o objetivo de identificar preditores de complicações vasculares em pacientes randomizados para as técnicas radial ou femoral com emprego de dispositivo de oclusão vascular (DOV). Resultados: Foram incluídos 240 pacientes, com média de idade de 63,0 ± 10,7 anos, sendo 30,8% diabéticos e, exceto pela maior prevalência de mulheres no grupo radial, não foram observadas diferenças clínicas entre os grupos. Intervenção coronária percutânea foi realizada em 86,7% dos casos. A taxa de complicações vasculares aos 30 dias foi de 13,3% no grupo radial, à custa de hematomas > 5 cm (6,7%) e oclusão arterial assintomática (5,8%), e de 12,5% no grupo femoral, à custa de hematomas > 5 cm, sem diferença significativa. Foram identificados como fatores de risco para complicações do acesso vascular o índice de massa corporal (IMC), o acidente vascular encefálico prévio, a maior duração do procedimento e o insucesso do DOV. Pela análise estratificada, o sexo feminino e o escore CRUSADE de alto ou muito alto risco foram variáveis preditoras de complicações apenas para o grupo femoral. No modelo multivariado, os fatores que permaneceram significantes foram o IMC e o insucesso do DOV. Conclusões: As técnicas radial e femoral, com o emprego de DOV, compartilharam variáveis preditoras de complicações. Fatores de risco, como sexo feminino e escore CRUSADE de alto risco, foram atenuados pela utilização da técnica radial


Background: The knowledge of risk factors related to vascular access complications in patients undergoing early invasive strategy allows the adoption of methods to minimize them. Methods: We performed a subanalysis of the ARISE study, aiming to identify predictors of vascular complications in patients randomized to the radial or femoral techniques with the use of vascular closure device (VCD). Results: A total of 240 patients with a mean age of 63.0 ± 10.7 years were included, with 30.8% of diabetics. Except for a higher prevalence of women in the radial group, there were no clinical differences between the groups. Percutaneous coronary intervention was performed in 86.7% of the cases. The rate of vascular complications after 30 days was 13.3% in the radial group, due to hematoma > 5 cm (6.7%) and asymptomatic artery occlusion (5.8%), and 12.5% in femoral group, due to hematoma > 5 cm, without significant difference. The following were identified as risk factors for vascular access complications: body mass index (BMI), previous stroke, longer duration of the procedure, and VCD failure. At the stratified analysis, female gender and high or very high-risk CRUSADE score were predictors of complications only for the femoral group. In the multivariate model, the factors that remained significant were BMI and VCD failure. Conclusions: The radial and femoral techniques, with the use of VCD, shared variables that were predictors of complications. Risk factors, such as female gender and high-risk CRUSADE score, were attenuated by the use of the radial technique

ABSTRACT

Eggshell evaluation may serve as an indicator of the effect of substances released in the environment, which may change eggshell shape, size, structure, and/or chemical composition. Additionally, exposure may interfere with hatching rates in contaminated eggs. The objective of this study was to better understand how exposure to the insecticide methyl parathion interferes with chemical changes in eggshells of Podocnemis expansa throughout their artificial incubation, as well as with egg hatchability. A total of 343 P. expansa eggs were collected in a natural reproduction area for the species. These eggs were transferred to and artificially incubated in the Wild Animal Teaching and Research Laboratory at Universidade Federal de Uberlândia. On the first day of artificial incubation, 0, 35, 350, and 3500 ppb of methyl parathion were incorporated to the substrate. Eggs were collected every three days for chemical analysis of eggshells. Hatchability was evaluated as the number of hatchlings in each treatment, for the eggs that were not used in the chemical analysis. Student's T-test was used for data on eggshell chemical composition, and the Binomial Test for Two Proportions was used in the hatchability analysis, at a 5% significance level. It was observed that the incorporation of methyl parathion to the substrate on the first day of artificial incubation of P. expansa eggs reduced the levels of total fat in the shells throughout their incubation, besides reducing egg hatchability.

ABSTRACT

Procedimentos coronários invasivos são comuns em pacientes com revascularizaçãomiocárdica cirúrgica prévia. Dados acerca do real papel e das possíveis limitações do acesso radial nesse subgrupo de pacientes são infrequentes. O objetivo deste estudo foi avaliar a factibilidade e a segurança do acesso radial em pacientes revascularizados cirurgicamente e que foram submetidos a procedimentos coronários invasivos diagnósticos ou terapêuticos subsequentes, comparando-o ao acesso femoral. Métodos: Entre maio de 2008 e novembro de 2014, foram analisados 959 procedimentos, sendo 539 realizados pelo acesso radial e 420 pelo femoral. Todos os operadores estavam familiarizados com ambos os acessos vasculares, cabendo a eles a decisão final sobre a via a ser utilizada. Resultados: A prevalência de insucesso foi de 6,1% vs. 0,5% (p < 0,0001), favorecendo a técnica femoral. As taxas de eventos cardíacos adversos graves (0,4% vs. 0,7%) e de complicações vasculares (1,5% vs. 1,9%)foram baixas, sem diferença entre os grupos. A opção pela técnica radial implicou em maior tempo de fluoroscopia e necessidade de cruzamento entre vias de acesso, principalmente em procedimentos diagnósticos. Conclusões: O acesso radial representou uma opção segura e eficaz para a realização de procedimentos coronários invasivos em pacientes cirurgicamente revascularizados, notadamente para os procedimentos terapêuticos...


Invasive coronary procedures are common in patients with previous coronary artery by-pass graft surgery. Data on the actual role and possible limitations of the radial approach in this subgroup of patients are sparse. The objective of this study was to evaluate the feasibility and safety of radial accessin patients surgically revascularized and who under went subsequent invasive diagnostic or therapeutic coronary procedures, comparing it to the femoral access. Methods: Between May 2008 and November 2014, 959 procedures were included; 539 performed by radial access and 420 by femoral access. All operators were familiar with both vascular accesses, and the final decision on the route to be used was left to the operators discretion. Results: The failure rate was 6.1% vs. 0.5% (p < 0.0001), favoring the femoral approach. Major adverse cardiac events (0.4% vs. 0.7%) and vascular complications (1.5% vs. 1.9%) rates were low, with no difference between groups. The choice of the radial approach resulted in greater fluoroscopy time and crossover rate between access routes, especially in diagnostic procedures. Conclusions: The radial approach was a safe and effective option for invasive coronary procedures in post coronary artery bypass graft patients, especially for therapeutic procedures...
